PART I

ITEM 1.    BUSINESS

        Unless we state otherwise or the context otherwise requires, references in this Annual Report on Form 10-K to "we," "our," "us" or "the Company" refer to Sterling Bancorp, Inc., a Michigan corporation, and its subsidiaries, including Sterling Bank & Trust, F.S.B., which we sometimes refer to as "Sterling Bank," "the Bank" or "our Bank."

        We are a unitary thrift holding company headquartered in Southfield, Michigan with our primary branch operations in San Francisco and Los Angeles, California. Through our wholly owned bank subsidiary, Sterling Bank and Trust, F.S.B., we offer a broad range of loan products to the residential and commercial markets, as well as retail banking services.

        In November 2017, we consummated a public offering of 15 million shares of our common stock and listed our common stock on the NASDAQ Capital Market under the symbol "SBT." The Company sold 7,692,308 shares of common stock and certain selling shareholders sold 7,307,692 shares of common stock. We received net proceeds of $85.5 million from the offering.

        We have a large and growing portfolio of adjustable rate residential mortgage loans. In our key residential loan program, we manage residential credit risks through a financial documentation process and programs with low loan to value ratios. Our risk management includes disciplined documentation of ability to repay, liquidity analysis and face-to-face customer interaction.

        We also operate substantial and growing commercial and construction lending businesses, utilizing a traditional community banking relationship-focused culture to identify strong borrowers with projects and operations in our branch network areas. We manage credit risks in our commercial and construction business through financial and relationship diligence with our customers and by financing projects within our branch footprint almost exclusively backed by personal guarantees.

        We believe growth should not come at the expense of asset quality. We have historically been able to focus on long-term returns and remain committed to responsible growth. We also believe our strong sales team, disciplined underwriting and culture of cost management have driven consistent earnings and exemplary net interest margins, efficiency metrics and shareholder returns.

Our History

        Sterling Bank was founded as a federally chartered thrift institution in 1984 in Southfield, Michigan by members of the Seligman family. By 2004 we had 10 branches in the Detroit metropolitan area. However, in the early 1990s, our owners and management recognized an opportunity to shift the Bank's focus to a rapidly growing market less dependent, as Detroit was, on a single industry. In 1994, the Bank established its first branch in San Francisco, California. In 2004, we made a strategic decision to sell all but one of our Detroit-area branches and focus nearly exclusively on the California market. In 2004, we divested 10 Michigan branches and by 2006, substantially reduced new lending in Michigan.

        Between 2004 and 2008, we expanded our San Francisco presence by opening an additional 7 branches. Our NPA/Total Assets ratio peaked at 5.7% in 2008, as we worked our way through credit issues related primarily to our legacy Michigan portfolios, which now represent a de minimis 1.1% of our loan portfolio. Since such time, our credit quality has improved significantly, with NPA/Total Assets as of December 31, 2017 of 0.13%.

        Since 2013, we have grown our branch network from 16 branches to our current total of 26 branches, including 20 in the San Francisco area, 4 in greater Los Angeles, one branch in New York City and our headquarters' branch in Michigan. During the first half of 2018, we plan to open a new branch in the Seattle market, where we currently have a loan production office, two additional branches in Southern California, and a loan production office in New York City, with the intent to eventually convert such office into a branch.

Lending Activities

        General.    Our lending strategy is to offer a broad range of loan products to the residential and commercial markets, tailored to our customers' needs. The majority of our loan portfolio consists of residential real estate mortgages, which accounted for 81.6% of our loan portfolio as of December 31, 2017. The balance of our loan portfolio consists of commercial real estate, construction, business loans, and commercial lines of credit.

        One- to Four-Family Residential Loans.    The origination of mortgage loans to enable borrowers to purchase or refinance existing homes comprises the largest portion of our loan portfolio. We offer fixed-rate and adjustable-rate mortgage loans with terms of up to 30 years. Among our significant products is our Advantage Loan program, which consists of one, three, five, or seven-year adjustable rate mortgages with a minimum 35% down payment requirement. We offer this product to underserved home buyers who have good credit, but may have limited credit history. Our Advantage Loan program constituted 77% of our residential loan portfolio as of December 31, 2017. Another significant product is our tenant-in-common, or TIC, loan program, which is similar to traditional co-op loans. Our primary market areas of San Francisco and Los Angeles contain a substantial number of two to six-unit residential buildings and a large amount of condominium conversions. Through our TIC program, we lend to owners of individual units within the building based on their relative ownership share. Our TIC loans generally consist of three, five and seven-year adjustable rate mortgages, with an average balance of approximately $0.5 million, and total outstanding loans of $434 million as of December 31, 2017. We also offer conventional conforming fixed-rate loans with terms of either 15, 20, or 30 years for mortgages of less than $0.6 million. The bulk of our conforming mortgage portfolio is held for sale, after which we typically retain servicing rights. In addition, we have a jumbo loan program for residential loans of between $0.6 million and $2.5 million, for which we offer both fixed and adjustable rates, which are also held for sale. Across our portfolio, our adjustable-rate mortgage loans are based on a 30-year amortization schedule and generally interest rates and payments adjust annually after a one, three, five, or seven-year initial fixed period. Interest rates on our adjustable-rate loans generally are adjusted to a rate typically equal to 350 to 395 basis points above the one-year LIBOR. Across our residential portfolio, our loan-to-value ratio was 62% as of December 31, 2017.

        We have a loan approval process through which we require not only financial and other information from our borrowers, but our loan officers are required to meet face-to-face with each of our borrowers in our Advantage program and produce a narrative documentation recommending the loan.

        Our single-family residential real estate portfolio is secured by real estate. Adverse developments affecting real estate values in our market areas could therefore increase the credit risk associated with these loans, impair the value of property pledged as collateral on loans, and affect our ability to sell the collateral upon foreclosure without a loss or additional losses. Loans held for sale consist primarily of first trust deed mortgages on single-family residential properties.

        Commercial Loans.    We offer a variety of commercial loan products, consisting primarily of commercial real estate loans, construction loans, business loans and business lines of credit. Our commercial loans are almost exclusively recourse loans, as we endeavor to secure personal guaranties on each loan we underwrite.

        Commercial Real Estate.    Our commercial real estate portfolio includes single room occupancy hotels, office, industrial, retail, multifamily and mixed-use properties. We focus almost exclusively on projects within or contiguous to our branch footprint, focusing on what we believe to be high quality credits with income-producing properties, strong cash flow characteristics and strong collateral profiles. At December 31, 2017, approximately 91% of the commercial real estate loan portfolio consisted of adjustable rate loans with an average reset of 36 months. Our loan-to-value policy limits are 75% for commercial real estate loans and 80% for multifamily.

Table of Contents

        The total commercial real estate portfolio totaled $247.1 million and $200.8 million at December 31, 2017 and 2016, of which $8.5 million and $11.9 million, respectively, were secured by owner occupied properties.

        A primary repayment risk for commercial real estate loans is the interruption or discontinuance of operating cash flows from the properties or businesses involved, which may be influenced by economic events, changes in governmental regulations or other events not under the control of the borrower. Additionally, adverse developments affecting commercial real estate values in our market areas could increase the credit risk associated with these loans, impair the value of property pledged as collateral for these loans, and affect our ability to sell the collateral upon foreclosure without a loss or additional losses.

        Construction loans.    Our construction loans are comprised primarily of residential construction, commercial construction and mixed-use development. We focus primarily on renovation projects, as opposed to ground-up developments. We believe that opportunities for construction lending will continue to increase, particularly in our San Francisco market, where historic preservation ordinances and other regulations limit the number of ground-up projects. Interest reserves are generally established on real estate construction loans. These loans are typically Prime based and typically have maturities of less than 18 months. Our loan-to-value policy limits are 80% for construction and 65% for land loans. The total construction portfolio totaled $192.3 million and $146.0 million at December 31, 2017 and 2016, respectively.

        The risks inherent in construction lending may affect adversely our results of operations. Such risks include, among other things, the possibility that contractors may fail to complete, or complete on a timely basis, construction of the relevant properties, substantial cost overruns in excess of original estimates and financing, market deterioration during construction, and lack of permanent take-out financing or presold properties. Loans secured by such properties also involve additional risk because they have no operating history. In these loans, loan funds are advanced upon the security of the project under construction (which is of uncertain value prior to completion of construction) and the estimated operating cash flow/sale proceeds to be generated by the completed project.

        Commercial Lines of Credit and Consumer Loans.    We also offer commercial lines of credit to businesses and individuals for business purposes. We seek to streamline the application process and provide quick decision-making to allow our customers to access credit quickly. These lines of credit are typically secured by real estate, inventory, equipment, accounts receivable and all assets. The total commercial line of credit and consumer loan portfolio totaled $40.8 million and $36.7 million at December 31, 2017 and 2016, respectively.

Investment Portfolio

        As of December 31, 2017, the fair value of our investment portfolio totaled $127 million, with an average effective yield of 1.42%. The estimated duration on the fixed income portion of our investment portfolio (fair value of $123 million) is 0.68 years. The primary objectives of the investment portfolio are to provide liquidity, generate economic value, and to be responsive to cash needs and assist in managing interest rate risk. The majority of our investment portfolio, or 95%, consists of U.S. treasuries, with 5% in other collateralized mortgage and debt obligations, equity or other securities. We regularly evaluate the composition of our investment portfolio as the interest rate yield curve changes and may sell investment securities from time to time to adjust our exposure to interest rates or to provide liquidity to meet loan demand.

        Our investment policy is reviewed at least annually by our board of directors. Overall investment goals are established by our board, CEO, CFO and members of our Asset and Liability Committee ("ALCO"). Our board of directors has delegated the responsibility of monitoring our investment activities to our management ALCO. Day-to-day activities pertaining to the securities portfolio are

4

Table of Contents

conducted under the supervision of our COO and CFO. We actively monitor our investments on an ongoing basis to identify any material changes in the securities. We also review our securities for potential other-than-temporary impairment at least quarterly.

Deposits

        The quality of our deposit franchise and access to stable funding are key components of our business. We offer traditional depository products, including checking, savings, money market, IRAs and certificates of deposits, to individuals and businesses through our branch network throughout our market areas. Deposits at the Bank are insured by the FDIC up to statutory limits. We offer customers traditional retail deposit products through our branch network and the ability to access their accounts through online and mobile banking platforms. We seek to grow our deposits through cross-selling to our loan customers, use of competitive rates, a focused marketing campaign, and multi-product clubs in which we offer varying benefits depending on the overall relationship with the customer. Our bankers are incentivized to acquire and maintain quality, core deposits as we depend on deposits to fund the majority of our loans. We believe that our long-standing and high quality relationships with our depositors who provide us with long-term funding are due to the convenience, rates and dedicated service we offer. We leverage our branch locations and deep network of customer relationships in our market areas to provide low-cost funding sources for our lending business.

Distribution Channels

        The primary markets in which we operate are San Francisco and greater Los Angeles, and our 24 branch network in these areas is our core distribution channel. We strive to take advantage of our focused footprint and deep-rooted relationships to target local customers with a diversified product offering.

        Our expansive local branch network enables us to gather deposits, promote the Sterling brand and customer loyalty, originate loans and other products and maintain relationships with our customers through regular community involvement. Our branch network is fundamental to our ability to achieve successful customer outreach in line with our culture, which promotes high-touch engagement with our customers and proactive solutions.

Risk Management

        We believe that effective risk management is of primary importance to our organization. Risk management refers generally to the activities by which we identify, measure, monitor, evaluate and manage the risks we face in the course of our banking activities. These include liquidity, interest rate, credit, operational, cyber/technological, legal, compliance, regulatory, strategic, financial and reputational risk exposures. Our board of directors and management team have created a risk-conscious culture that is focused on quality growth, which includes infrastructure capable of addressing the evolving risks we face, as well as the changing regulatory and compliance landscape. Our risk management approach employs comprehensive policies and processes to establish robust governance and emphasizes personal ownership and accountability for risk with our employees. We believe a disciplined and conservative underwriting approach has been the key to our strong asset quality.

        Our management of interest rate risk is overseen by our Board ALCO, and implemented by our Management ALCO based on a risk management infrastructure approved by our board of directors that outlines reporting and measurement requirements. In particular, this infrastructure sets limits, calculated quarterly, for various interest rate-related metrics, our economic value of equity and net interest income simulations involving parallel shifts in interest rate curves. Steepening and flattening yield curves and various prepayment and deposit duration assumptions are prepared at least annually. Our interest rate management policies also require periodic review and documentation of all key

5

assumptions used, such as identifying appropriate interest rate scenarios, setting loan prepayment rates and deposit durations based on historical analysis.

Competition

        The financial services industry is highly competitive as we compete for loans, deposits and customer relationships in our market. Competition involves efforts to retain current clients, make new loans and obtain new deposits, increase the scope and sophistication of services offered and offer competitive interest rates paid on deposits and charged on loans. Within our branch footprint, we primarily face competition from national, regional and other local financial institutions that have established branch networks throughout the San Francisco and Los Angeles areas as well as new markets, giving them visible retail presence to customers.

        In mortgage banking, we face competition from a wide range of national financial institutions, regional and local community banks, as well as credit unions and national mortgage underwriters. In commercial banking, we face competition to underwrite loans to sound, stable businesses and real estate projects at competitive price levels that make sense for our business and risk profile. Our major commercial bank competitors include larger national, regional and local financial institutions that may have the ability to make loans on larger projects than we can or provide a larger mix of product offerings. We also compete with smaller local financial institutions that may have aggressive pricing and unique terms on various types of loans and, increasingly, financial technology platforms that offer their products exclusively through web-based portals.

        In retail banking, we primarily compete with national and local banks that have visible retail presence and personnel in our market areas. The primary factors driving competition in consumer banking are customer service, interest rates, fees charged, branch location and hours of operation and the range of products offered. We compete for deposits by advertising, offering competitive interest rates and seeking to provide a higher level of personal service. We also face competition from non-traditional alternatives to banks such as credit unions, internet based banks, money centers, money market mutual funds and cash management accounts.

        We believe our ability to provide a flexible, sophisticated product offering and an efficient process to our customers allows us to stay competitive in the financial services environment. Our local presence and hands-on approach enables us to provide a high level of service that our customers value.

Other Subsidiaries

        Quantum Capital Management.    In April 2017 we acquired Quantum, an investment management platform that historically focused on hedged equity and mid-cap, small-cap and micro-cap portfolio strategies. As of December 31, 2017, Quantum had $453 million in assets held under management.

        Sterling Wealth Management.    Sterling Wealth Management, a subsidiary of the Bank, provides wealth management services to certain of our customers. We have a customer service representative program through which we intend to establish a traditional fee-based, wealth management platform that will deliver a revenue stream for the Bank while providing clients with an enhanced level of investment advisory services.

Information Technology Systems

        We devote significant resources to maintain stable, reliable, efficient and scalable information technology systems. We utilize our own single, highly integrated core processing system that improves cost efficiency and protects us against escalating rates and termination fees from third party providers and positions us to be in control of new product development and time to market. We work with our third-party vendors to monitor and maximize the efficiency of our use of their applications. We use

6

Table of Contents

integrated systems to originate and process loans and deposit accounts, which reduces processing time, improves customer experience and reduces costs.

        We have an Information Security Officer who reports to the General Counsel, whom we charge with the review and implementation of strategies, policies, managed services, technology, and any other resource that could aid in the effort against cybercrime. Our Information Systems ("IS") Department proactively identifies and monitors systems to analyze risk to the organization and implement mitigating controls where appropriate. Formal business continuity and disaster recovery exercises are conducted annually. Additionally, we involve independent firms to perform an audit and internal and external penetration tests on our IS systems on at least an annual basis.

SUPERVISION AND REGULATION

General

        As a federal savings bank, Sterling Bank is subject to primary examination and regulation by the OCC and, as an insured depository institution, the FDIC. The federal system of regulation and supervision establishes a comprehensive framework of activities in which Sterling Bank may engage and is intended primarily for the protection of depositors and the FDIC's Deposit Insurance Fund rather than our shareholders. Sterling Bank also is a member of, and owns stock in, the Federal Home Loan Bank of Indianapolis, which is one of the 11 regional banks in the Federal Home Loan Bank System.

        As a unitary thrift holding company, Sterling Bancorp is required to comply with the rules and regulations of the Federal Reserve Board. It is required to file certain reports with the Federal Reserve Board and is subject to examination by and the enforcement authority of the Federal Reserve Board. Sterling Bancorp is also subject to the rules and regulations of the Securities and Exchange Commission under the federal securities laws.

        Under this system of regulation, the regulatory authorities have extensive discretion in connection with their supervisory, enforcement, rulemaking and examination activities and policies, including rules or policies that: establish minimum capital levels; restrict the timing and amount of dividend payments; govern the classification of assets; determine the adequacy of loan loss reserves for regulatory purposes; and establish the timing and amounts of assessments and fees. Moreover, as part of their examination authority, the banking regulators assign numerical ratings to banks and savings institutions relating to capital, asset quality, management, liquidity, earnings and other factors. These ratings are inherently subjective and the receipt of a less than satisfactory rating in one or more category may result in enforcement action by the banking regulators against a financial institution. A less than satisfactory rating may also prevent a financial institution, such as Sterling Bank or Sterling Bancorp, from obtaining necessary regulatory approvals to access the capital markets, pay dividends, acquire other financial institutions or establish new branches.

        In addition, we must comply with anti-money laundering and anti-terrorism laws and regulations, Community Reinvestment Act laws and regulations, and fair lending laws and regulations. Government agencies have the authority to impose monetary penalties and other sanctions on institutions that fail to comply with these laws and regulations, which could significantly affect our business activities, including our ability to expand our branch network or acquire other financial institutions.

        Any change in applicable laws or regulations, whether by the OCC, the FDIC, the Federal Reserve Board or Congress, could have a material adverse impact on the operations and financial performance of Sterling Bancorp and Sterling Bank.

        Set forth below is a brief description of material regulatory requirements that are or will be applicable to Sterling Bank and Sterling Bancorp. The description is limited to certain material aspects of the statutes and regulations addressed, and is not intended to be a complete description of such statutes and regulations and their effects on Sterling Bank and Sterling Bancorp.

Federal Banking Regulation

        Business Activities.    A federal savings bank derives its lending and investment powers from the Home Owners' Loan Act, as amended, and applicable federal regulations. Under these laws and regulations, Sterling Bank may invest in mortgage loans secured by residential and commercial real estate, commercial business and consumer loans, certain types of debt securities and certain other assets, subject to applicable limits. Sterling Bank may also establish subsidiaries that may engage in certain activities not otherwise permissible for Sterling Bank, including wealth and investment management.

        Capital Requirements.    Federal regulations require Sterling Bancorp and Sterling Bank to meet several minimum capital standards. In the case of Sterling Bank, minimum capital standards include a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-based assets ratio of 6.0%, a total capital to risk-based assets ratio of 8.0%, and a 4.0% Tier 1 capital to total assets leverage ratio. These capital requirements were effective January 1, 2015 and are the result of a final rule implementing recommendations of the Basel Committee on Banking Supervision and certain requirements of the Dodd-Frank Act.

        In determining the amount of risk-weighted assets for purposes of calculating risk-based capital ratios, all assets, including certain off-balance sheet assets (e.g., recourse obligations, direct credit substitutes, residual interests) are multiplied by a risk weight factor assigned by the regulations based on the risks believed inherent in the type of asset. Higher levels of capital are required for asset categories believed to present greater risk. Common equity Tier 1 capital is generally defined as common shareholders' equity and retained earnings. Tier 1 capital is generally defined as common equity Tier 1 and additional Tier 1 capital. Additional Tier 1 capital includes certain noncumulative perpetual preferred stock and related surplus and minority interests in equity accounts of consolidated subsidiaries. Total capital includes Tier 1 capital (common equity Tier 1 capital plus additional Tier 1 capital) and Tier 2 capital. Tier 2 capital is comprised of capital instruments and related surplus, meeting specified requirements, and may include cumulative preferred stock and long-term perpetual preferred stock, mandatory convertible securities, intermediate preferred stock and subordinated debt. Also included in Tier 2 capital is the allowance for loan and lease losses limited to a maximum of 1.25% of risk-weighted assets and, for institutions that have exercised an opt-out election regarding the treatment of Accumulated Other Comprehensive Income, up to 45% of net unrealized gains on available-for-sale equity securities with readily determinable fair market values. Calculation of all types of regulatory capital is subject to deductions and adjustments specified in the regulations. In assessing an institution's capital adequacy, the OCC takes into consideration not only these numeric factors, but qualitative factors as well, and has the authority to establish higher capital requirements for individual institutions where deemed necessary.

        In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a "capital conservation buffer" consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The capital conservation buffer requirement is being phased in, a process which began January 1, 2016 at 0.625% of risk-weighted assets and increases by such amount each year until fully implemented at 2.5% of risk-weighted assets on January 1, 2019.

        At December 31, 2017, the Company and the Bank met all regulatory capital requirements to which they are subject.

        Loans-to-One Borrower.    Generally, a federal savings bank may not make a loan or extend credit to a single or related group of borrowers in excess of 15% of unimpaired capital and surplus. An additional amount may be loaned, equal to 10% of unimpaired capital and surplus, if the loan is secured by readily marketable collateral, which generally does not include real estate. As of December 31, 2017, Sterling Bank was in compliance with the loans-to-one borrower limitations.

Table of Contents

        Qualified Thrift Lender Test.    As a federal savings bank, Sterling Bank must satisfy the qualified thrift lender, or "QTL," test. Under the QTL test, Sterling Bank must maintain at least 65% of its "portfolio assets" in "qualified thrift investments" (primarily residential mortgages and related investments, including mortgage-backed securities) in at least nine months of the most recent 12-month period. "Portfolio assets" generally means total assets of a savings bank, less the sum of specified liquid assets up to 20% of total assets, goodwill and other intangible assets, and the value of property used in the conduct of the savings bank's business.

        Sterling Bank also may satisfy the QTL test by qualifying as a "domestic building and loan association" as defined in the Internal Revenue Code of 1986, as amended. This test generally requires a savings bank to have at least 75% of its deposits held by the public and earn at least 25% of its income from loans and U.S. government obligations. Alternatively, a savings bank can satisfy this test by maintaining at least 60% of its assets in cash, real estate loans and U.S. Government or state obligations.

        A savings bank that fails the qualified thrift lender test must operate under specified restrictions set forth in the Home Owners' Loan Act. The Dodd-Frank Act made noncompliance with the QTL test subject to agency enforcement action. At December 31, 2017, Sterling Bank satisfied the QTL test.

        Capital Distributions.    Federal regulations govern capital distributions by a federal savings bank, which include cash dividends, stock repurchases and other transactions charged to the savings bank's capital account. A federal savings bank must file an application with the OCC for approval of a capital distribution if:

•

the total capital distributions for the applicable calendar year exceed the sum of the savings bank's net income for that year to date plus the savings bank's retained net income for the preceding two years;



•

the savings bank would not be at least adequately capitalized following the distribution;



•

the distribution would violate any applicable statute, regulation, agreement or regulatory condition; or



•

the savings bank is not eligible for expedited treatment of its filings, generally due to an unsatisfactory CAMELS rating or being subject to a cease and desist order or formal written agreement that requires action to improve the institution's financial condition.

        Even if an application is not otherwise required, every savings bank that is a subsidiary of a unitary thrift holding company, such as Sterling Bank, must still file a notice with the Federal Reserve Board at least 30 days before the board of directors declares a dividend or approves a capital distribution.

        A notice or application related to a capital distribution may be disapproved if:

•

the federal savings bank would be undercapitalized following the distribution;



•

the proposed capital distribution raises safety and soundness concerns; or



•

the capital distribution would violate a prohibition contained in any statute, regulation or agreement.

        In addition, the Federal Deposit Insurance Act provides that an insured depository institution may not make any capital distribution if, after making such distribution, the institution would fail to meet any applicable regulatory capital requirement.

        Community Reinvestment Act and Fair Lending Laws.    All federal savings banks have a responsibility under the Community Reinvestment Act and related regulations to help meet the credit needs of their communities, including low and moderate-income borrowers. In connection with its examination of a federal savings bank, the OCC is required to assess the federal savings bank's record of compliance with the Community Reinvestment Act. A savings bank's failure to comply with the provisions of the

9

---

Table of Contents

Community Reinvestment Act could, at a minimum, result in denial of certain corporate applications such as branch expansion or mergers, or in restrictions on its activities. In addition, the Equal Credit Opportunity Act and the Fair Housing Act prohibit lenders from discriminating in their lending practices on the basis of characteristics specified in those statutes. The failure to comply with the Equal Credit Opportunity Act and the Fair Housing Act could result in enforcement actions by the OCC, as well as other federal regulatory agencies and the Department of Justice.

        The Community Reinvestment Act requires all institutions insured by the Federal Deposit Insurance Corporation to publicly disclose their rating. Sterling Bank received a "satisfactory" Community Reinvestment Act rating in its most recent federal examination.

        Transactions with Related Parties.    A federal savings bank's authority to engage in transactions with its affiliates is limited by Sections 23A and 23B of the Federal Reserve Act and federal regulation. An affiliate is generally a company that controls, or is under common control with, an insured depository institution such as Sterling Bank. Sterling Bancorp is an affiliate of Sterling Bank because of its control of Sterling Bank. A subsidiary of a bank that is not also a depository institution or a "financial subsidiary" under federal law is not treated as an affiliate of the bank for the purposes of Sections 23A and 23B; however, the OCC has the discretion to treat subsidiaries of a bank as affiliates on a case-by-case basis. Section 23A limits the extent to which a bank or its subsidiaries may engage in "covered transactions" with any one affiliate to 10% of the bank's capital stock and surplus. There is an aggregate limit of 20% of the bank's capital stock and surplus for such transactions with all affiliates. The term "covered transaction" includes, among other things, the making of a loan to an affiliate, a purchase of assets from an affiliate, the issuance of a guarantee on behalf of an affiliate and the acceptance of securities of an affiliate as collateral for a loan. All such transactions are required to be on terms and conditions that are consistent with safe and sound banking practices and no transaction may involve the acquisition of any "low quality asset" from an affiliate. Certain covered transactions, such as loans to or guarantees on behalf of an affiliate, must be secured by collateral in amounts ranging from 100 to 130 percent of the loan amount, depending upon the type of collateral. In addition, Section 23B requires that any covered transaction (and specified other transactions) between a bank and an affiliate must be on terms and conditions that are substantially the same, or at least as favorable, to the bank, as those that would be provided to a non-affiliate.

        A bank's loans to its executive officers, directors, any owner of more than 10% of its stock (each, an "insider") and certain entities affiliated with any such person (an insider's "related interest") are subject to the conditions and limitations imposed by Section 22(h) of the Federal Reserve Act and the FRB's Regulation O. The aggregate amount of a bank's loans to any insider and the insider's related interests may not exceed the loans-to-one-borrower limit applicable to national banks. Aggregate loans by a bank to its insiders and insiders' related interests may not exceed the bank's unimpaired capital and unimpaired surplus. With certain exceptions, such as education loans and certain residential mortgages, a bank's loans to its executive officers, may not exceed the greater of $25,000 or 2.5% of the bank's unimpaired capital and unimpaired surplus, but in no event more than $100,000. Regulation O also requires that any loan to an insider or a related interest of an insider be approved in advance by a majority of the board of directors of the bank, with any interested director not participating in the voting, if the loan, when aggregated with any existing loans to that insider or the insider's related interests, would exceed the lesser or $500,000 or 5% of the bank's unimpaired capital and surplus. Generally, such loans must be made on substantially the same terms and follow credit underwriting procedures that are no less stringent than, those that are prevailing at the time for comparable transactions with other persons and must not present more than a normal risk of collectability. An exception is made for extensions of credit made pursuant to a benefit or compensation plan of a bank that is widely available to employees of the bank and that does not give any preference to insiders of the bank over other employees of the bank. As of December 31, 2017, none of our insiders had any outstanding loans with the Bank.

        Enforcement.    The OCC has primary enforcement responsibility over federal savings banks and has authority to bring enforcement action against all "institution-affiliated parties," including directors, officers, shareholders, attorneys, appraisers and accountants who knowingly or recklessly participate in wrongful action likely to have an adverse effect on a federal savings bank. Formal enforcement action by the OCC may range from the issuance of a capital directive, formal agreement or cease and desist order to removal of officers and/or directors of the institution and the appointment of a receiver or conservator. Civil penalties cover a wide range of violations and actions, and range up to $25,000 per day, unless a finding of reckless disregard is made, in which case penalties may be as high as $1 million per day. The FDIC also has the authority to terminate deposit insurance or recommend to the OCC that enforcement action be taken with respect to a particular savings bank. If such action is not taken, the FDIC has authority to take the action under specified circumstances.

        Standards for Safety and Soundness.    Federal law requires each federal banking agency to prescribe certain standards for all insured depository institutions. These standards relate to, among other things, internal controls, information systems and audit systems, loan documentation, credit underwriting, interest rate risk exposure, asset growth, compensation and other operational and managerial standards as the agency deems appropriate. Interagency guidelines set forth the safety and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions before capital becomes impaired. If the appropriate federal banking agency determines that an institution fails to meet any standard prescribed by the guidelines, the agency may require the institution to submit to the agency an acceptable plan to achieve compliance with the standard. If an institution fails to meet these standards, the appropriate federal banking agency may require the institution to implement an acceptable compliance plan. Failure to implement such a plan can result in further enforcement action, including the issuance of a cease and desist order or the imposition of civil money penalties.

        Interstate Banking and Branching.    Federal law permits well capitalized and well managed holding companies to acquire banks in any state, subject to Federal Reserve Board approval, certain concentration limits and other specified conditions. Interstate mergers of banks are also authorized, subject to regulatory approval and other specified conditions. In addition, among other things, certain amendments made by the Dodd-Frank Act permit banks to establish de novo branches on an interstate basis provided that branching is authorized by the law of the host state for the banks chartered by that state.

        Prompt Corrective Action.    Federal law requires, among other things, that federal bank regulators take "prompt corrective action" with respect to institutions that do not meet minimum capital requirements. For this purpose, the law establishes five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. The applicable OCC regulations were amended to incorporate the previously mentioned increased regulatory capital standards that were effective January 1, 2015. Under the amended regulations, an institution is deemed to be "well capitalized" if it has a total risk-based capital ratio of 10.0% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, a leverage ratio of 5.0% or greater and a common equity Tier 1 ratio of 6.5% or greater. An institution is "adequately capitalized" if it has a total risk-based capital ratio of 8.0% or greater, a Tier 1 risk-based capital ratio of 6.0% or greater, a leverage ratio of 4.0% or greater and a common equity Tier 1 ratio of 4.5% or greater. An institution is "undercapitalized" if it has a total risk-based capital ratio of less than 8.0%, a Tier 1 risk-based capital ratio of less than 6.0%, a leverage ratio of less than 4.0% or a common equity Tier 1 ratio of less than 4.5%. An institution is deemed to be "significantly undercapitalized" if it has a total risk-based capital ratio of less than 6.0%, a Tier 1 risk-based capital ratio of less than 4.0%, a leverage ratio of less than 3.0% or a common equity Tier 1 ratio of less than 3.0%. An institution is considered to be "critically undercapitalized" if it has a ratio of tangible equity (as defined in the regulations) to total assets that is equal to or less than 2.0%.

Table of Contents

        At each successive lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, restrictions or prohibitions on payment of dividends, and restrictions on the acceptance of brokered deposits. Furthermore, if an insured depository institution is classified in one of the undercapitalized categories, it is required to submit a capital restoration plan to the appropriate federal banking agency, and the holding company must guarantee the performance of that plan. Based upon its capital levels, a bank that is classified as well-capitalized, adequately capitalized, or undercapitalized may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition, or an unsafe or unsound practice, warrants such treatment. An undercapitalized bank's compliance with a capital restoration plan is required to be guaranteed by any company that controls the undercapitalized institution in an amount equal to the lesser of 5.0% of the institution's total assets when deemed undercapitalized or the amount necessary to achieve the status of adequately capitalized. If an "undercapitalized" bank fails to submit an acceptable plan, it is treated as if it is "significantly undercapitalized." "Significantly undercapitalized" banks must comply with one or more of a number of additional restrictions, including but not limited to an order by the Federal Reserve Board to sell sufficient voting stock to become adequately capitalized, requirements to reduce total assets, cease receipt of deposits from correspondent banks or dismiss directors or officers, and restrictions on interest rates paid on deposits, compensation of executive officers and capital distributions by the parent holding company. "Critically undercapitalized" institutions are subject to additional measures including, subject to a narrow exception, the appointment of a receiver or conservator within 270 days after it obtains such status.

        At December 31, 2017, Sterling Bank met the criteria for being considered "well capitalized."

        Insurance of Deposit Accounts.    The Deposit Insurance Fund of the FDIC insures deposits at FDIC-insured financial institutions such as Sterling Bank. Deposit accounts in Sterling Bank are insured by the FDIC generally up to a maximum of $250,000 per separately insured depositor. The FDIC charges insured depository institutions premiums to maintain the Deposit Insurance Fund.

        Under the FDIC's risk-based assessment system, insured institutions are assigned to one of four risk categories based on supervisory evaluations, regulatory capital levels and certain other risk factors. Rates are based on each institution's risk category and certain specified risk adjustments. Institutions deemed to be less risky pay lower rates while institutions deemed riskier pay higher rates. Assessment rates (inclusive of possible adjustments) currently range from 2¹/2 to 45 basis points of each institution's total assets less tangible capital. The FDIC may increase or decrease the scale uniformly, except that no adjustment can deviate more than two basis points from the base scale without notice and comment rulemaking. The FDIC's current system represents a change, required by the Dodd-Frank Act, from its prior practice of basing the assessment on an institution's deposits.

        The Dodd-Frank Act increased the minimum target Deposit Insurance Fund ratio from 1.15% of estimated insured deposits to 1.35% of estimated insured deposits. The FDIC must seek to achieve the 1.35% ratio by September 30, 2020. Insured institutions with assets of $10 billion or more are supposed to fund the increase. The Dodd-Frank Act eliminated the 1.5% maximum fund ratio, instead leaving it to the discretion of the FDIC, which has exercised that discretion by establishing a long range fund ratio of 2%.

        The FDIC has authority to increase insurance assessments. Any significant increases could have an adverse effect on the operating expenses and results of operations of Sterling Bank. We cannot predict what assessment rates will be in the future.

        Insurance of deposits may be terminated by the FDIC upon a finding that an institution has engaged in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations,

Table of Contents

or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. We do not know of any practice, condition or violation that may lead to termination of our deposit insurance.

        In addition to the FDIC assessments, the Financing Corporation ("FICO") is authorized to impose and collect, with the approval of the FDIC, assessments for anticipated payments, issuance costs and custodial fees on bonds issued by the FICO in the 1980s to recapitalize the former Federal Savings and Loan Insurance Corporation. The bonds issued by the FICO are due to mature in 2017 through 2019. For the 3rd quarter expense paid in the quarter ended December 31, 2017, the annualized FDIC assessment was equal to 5.53 basis points of total assets less tangible capital, and the annualized FICO assessment was equal to 0.46 basis points of total assets less total tangible capital.

        Supervisory Assessments.    OCC-chartered banks are required to pay supervisory assessments to the OCC to fund its operations. The amount of the assessment paid by a federally-chartered bank to the OCC is calculated on the basis of the institution's total assets, including consolidated subsidiaries, as reported to the OCC. During the year ended December 31, 2017 and 2016, the Bank paid supervisory assessments to the OCC totaling $470,000 and $390,000, respectively.

        Privacy Regulations.    Federal regulations generally require that Sterling Bank disclose its privacy policy, including identifying with whom it shares a customer's "non-public personal information," to customers at the time of establishing the customer relationship and annually thereafter. In addition, Sterling Bank is required to provide its customers with the ability to "opt-out" of having their personal information shared with unaffiliated third parties and not to disclose account numbers or access codes to non-affiliated third parties for marketing purposes. Sterling Bank currently has a privacy protection policy in place and believes that such policy is in compliance with the regulations.

        USA Patriot Act.    Sterling Bank is subject to the USA PATRIOT Act, which gives federal agencies additional powers to address terrorist threats through enhanced domestic security measures, expanded surveillance powers, increased information sharing, and broadened anti-money laundering requirements. The USA PATRIOT Act contains provisions intended to encourage information sharing among bank regulatory agencies and law enforcement bodies and imposes affirmative obligations on financial institutions, such as enhanced recordkeeping and customer identification requirements.

        Prohibitions Against Tying Arrangements.    Federal savings banks are prohibited, subject to some exceptions, from extending credit to or offering any other service, or fixing or varying the consideration for such extension of credit or service, on the condition that the customer obtain some additional service from the institution or its affiliates or not obtain services of a competitor of the institution.

Other Regulations

        Interest and other charges collected or contracted for by Sterling Bank are subject to state usury laws and federal laws concerning interest rates. Loan operations are also subject to state and federal laws applicable to credit transactions, such as the:

•

Truth-In-Lending Act, governing disclosures of credit terms to consumer borrowers;



•

Home Mortgage Disclosure Act of 1975, requiring financial institutions to provide information to enable the public and public officials to determine whether a financial institution is fulfilling its obligation to help meet the housing needs of the community it serves;



•

Equal Credit Opportunity Act, prohibiting discrimination on the basis of race, creed or other prohibited factors in extending credit;



•

Fair Debt Collection Act, governing the manner in which consumer debts may be collected by collection agencies;



•

Truth in Savings Act; governing disclosure of information about deposit accounts to customers;

•

Fair Credit Reporting Act of 1978, governing the use and provision of information to credit reporting agencies; and



•

Rules and regulations of the various federal and state agencies charged with the responsibility of implementing such federal and state laws.

        The deposit operations of Sterling Bank also are subject to, among others, the:

•

Right to Financial Privacy Act, which imposes a duty to maintain confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records;



•

Check Clearing for the 21st Century Act (also known as "Check 21"), which gives "substitute checks," such as digital check images and copies made from that image, the same legal standing as the original paper check; and



•

Electronic Funds Transfer Act and Regulation E promulgated thereunder, which govern automatic deposits to and withdrawals from deposit accounts and customers' rights and liabilities arising from the use of automated teller machines and other electronic banking services.

Federal Reserve System

        Under FRB regulations, Sterling Bank is required to maintain reserves at the Federal Reserve Bank against its transaction accounts, including checking and NOW accounts. The regulations currently require that reserves of 3% be maintained against aggregate transaction accounts over $16.0 million and 10% against that portion of total transaction accounts in excess of $122.3 million. The first $16.0 million of otherwise reservable balances are exempted from the reserve requirements. The Bank is in compliance with these requirements. The requirements are adjusted annually by the FRB. The FRB began paying interest on reserves in 2008, currently 1.50%.

Federal Home Loan Bank System

        Sterling Bank is a member of the Federal Home Loan Bank System, which consists of 11 regional Federal Home Loan Banks. The Federal Home Loan Bank provides a central credit facility primarily for member institutions. Members of the Federal Home Loan Bank are required to acquire and hold shares of capital stock in the Federal Home Loan Bank. Sterling Bank was in compliance with this requirement at December 31, 2017. Based on redemption provisions of the Federal Home Loan Bank of Indianapolis, the stock has no quoted market value and is carried at cost. Sterling Bank reviews for impairment, based on the ultimate recoverability, the cost basis of the Federal Home Loan Bank of Indianapolis stock. As of December 31, 2017, no impairment has been recognized.

Holding Company Regulation

        Sterling Bancorp is a unitary thrift holding company subject to regulation and supervision by the Federal Reserve Board. The Federal Reserve Board has enforcement authority over Sterling Bancorp and its non-savings institution subsidiaries. Among other things, this authority permits the Federal Reserve Board to restrict or prohibit activities that are determined to be a risk to Sterling Bank.

        As a unitary thrift holding company, Sterling Bancorp's activities will be limited to those activities permissible by law for financial holding companies. A financial holding company may engage in activities that are financial in nature, incidental to financial activities or complementary to a financial activity. Such activities include lending and other activities permitted for bank holding companies under Section 4(c)(8) of the Bank Holding Company Act, insurance and underwriting equity securities.

        Federal law prohibits a unitary thrift holding company, directly or indirectly, or through one or more subsidiaries, from acquiring more than 5% of another savings institution or unitary thrift holding company without prior written approval of the Federal Reserve Board, and from acquiring or retaining

14

---

Table of Contents

control of any depository institution. In evaluating applications by holding companies to acquire savings institutions, the Federal Reserve Board must consider such things as the financial and managerial resources and future prospects of the company and institution involved, the effect of the acquisition on and the risk to the federal deposit insurance fund, the convenience and needs of the community and competitive factors. A unitary thrift holding company may not acquire a savings institution in another state and hold the target institution as a separate subsidiary unless it is a supervisory acquisition under Section 13(k) of the Federal Deposit Insurance Act or the law of the state in which the target is located authorizes such acquisitions by out-of-state companies.

        Capital Requirements.    As a unitary thrift holding company, Sterling Bancorp is subject to consolidated regulatory capital requirements that are similar to those that apply to Sterling Bank. See "Regulation and Supervision—Federal Banking Regulation—Capital Requirements."

        The Dodd-Frank Act extended the "source of strength" doctrine to unitary thrift holding companies. The Federal Reserve Board has promulgated regulations implementing the "source of strength" policy that require holding companies to act as a source of strength to their subsidiary depository institutions by providing capital, liquidity and other support in times of financial stress.

        The Federal Reserve Board has issued a policy statement regarding the payment of dividends and the repurchase of shares of common stock by bank holding companies and unitary thrift holding companies. In general, the policy provides that dividends should be paid only out of current earnings and only if the prospective rate of earnings retention by the holding company appears consistent with the organization's capital needs, asset quality and overall financial condition. Regulatory guidance provides for prior regulatory consultation with respect to capital distributions in certain circumstances such as where the company's net income for the past four quarters, net of dividends previously paid over that period, is insufficient to fully fund the dividend or the company's overall rate of earnings retention is inconsistent with the company's capital needs and overall financial condition. The ability of a holding company to pay dividends may be restricted if a subsidiary bank becomes undercapitalized. The policy statement also states that a holding company should inform the Federal Reserve Board supervisory staff prior to redeeming or repurchasing common stock or perpetual preferred stock if the holding company is experiencing financial weaknesses or if the repurchase or redemption would result in a net reduction, as of the end of a quarter, in the amount of such equity instruments outstanding compared with the beginning of the quarter in which the redemption or repurchase occurred. These regulatory policies may affect the ability of Sterling Bancorp to pay dividends, repurchase shares of common stock or otherwise engage in capital distributions.

        In order for Sterling Bancorp to be regulated as a unitary thrift holding company by the Federal Reserve Board, rather than as a bank holding company, Sterling Bank must qualify as a "qualified thrift lender" under federal regulations or satisfy the "domestic building and loan association" test under the Internal Revenue Code. Under the qualified thrift lender test, a savings institution is required to maintain at least 65% of its "portfolio assets" (total assets less: (i) specified liquid assets up to 20% of total assets; (ii) intangible assets, including goodwill; and (iii) the value of property used to conduct business) in certain "qualified thrift investments" (primarily residential mortgages and related investments, including certain mortgage-backed and related securities) in at least nine out of each 12 month period. At December 31, 2017, Sterling Bank maintained 86.7% of its portfolio assets in qualified thrift investments and was in compliance with the qualified thrift lender requirement.

Sarbanes-Oxley Act of 2002

        The Sarbanes-Oxley Act of 2002 is intended to improve corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities laws. We have policies, procedures and systems designed to comply with these regulations,

15

---

Table of Contents

and we review and document such policies, procedures and systems to ensure continued compliance with these regulations.

Change in Control Regulations

        Under the Change in Bank Control Act, no person may acquire control of a unitary thrift holding company such as Sterling Bancorp unless the Federal Reserve Board has been given 60 days prior written notice and has not issued a notice disapproving the proposed acquisition, taking into consideration certain factors, including the financial and managerial resources of the acquirer and the competitive effects of the acquisition. Control, as defined under federal law, means ownership, control of or holding irrevocable proxies representing more than 25% of any class of voting stock, control in any manner of the election of a majority of the institution's directors, or a determination by the regulator that the acquiror has the power, directly or indirectly, to exercise a controlling influence over the management or policies of the institution. Acquisition of more than 10% of any class of a unitary thrift holding company's voting stock constitutes a rebuttable determination of control under the regulations under certain circumstances including where, as in our case, the company has registered securities under Section 12 of the Securities Exchange Act of 1934.

        In addition, federal regulations provide that no company may acquire control of a unitary thrift holding company without the prior approval of the Federal Reserve Board. Any company that acquires such control becomes subject to registration, examination and regulation by the Federal Reserve Board.

Emerging Growth Company Status

        The JOBS Act, which was enacted in April 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.07 billion during its most recently completed fiscal year qualifies as an "emerging growth company." Sterling Bancorp, Inc. qualifies as an emerging growth company under the JOBS Act.

        An "emerging growth company" may choose not to hold shareholder votes to approve annual executive compensation (more frequently referred to as "say-on-pay" votes) or executive compensation payable in connection with a merger (more frequently referred to as "say-on-golden parachute" votes). An emerging growth company also is not subject to the requirement that its auditors attest to the effectiveness of the company's internal control over financial reporting, and can provide scaled disclosure regarding executive compensation. Finally, an emerging growth company may elect to comply with new or amended accounting pronouncements in the same manner as a private company, but must make such election when the company is first required to file a registration statement. Such an election is irrevocable during the period a company is an emerging growth company. Sterling Bancorp, Inc. has elected to comply with new or amended accounting pronouncements in the same manner as a non-emerging growth public company.

        A company loses emerging growth company status on the earlier of: (i) the last day of the fiscal year of the company during which it had total annual gross revenues of $1.07 billion or more; (ii) the last day of the fiscal year of the issuer following the fifth anniversary of the date of the first sale of common equity securities of the company pursuant to an effective registration statement under the Securities Act of 1933; (iii) the date on which such company has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; or (iv) the date on which such company is deemed to be a "large accelerated filer" under Securities and Exchange Commission regulations (generally, at least $700 million of voting and non-voting equity held by non-affiliates).

ITEM 1A.    RISK FACTORS

        We face a number of significant risks and uncertainties in connection with our operations. Our business and the results of our operations could be materially adversely affected by the factors described below. The risks described below are not the only risks facing our operations. Risks and uncertainties not currently known to us or that we currently deem to be immaterial also could have a material adverse impact on our business and results of operations.

Risks Related to Our Business

Our concentration in residential mortgage loans exposes us to risks.

        At December 31, 2017 and 2016, one-to-four family residential real estate loans amounted to $2.13 billion and $1.61 billion, or 82% and 81%, respectively, of our total loan portfolio, and we intend to continue this type of lending in the foreseeable future. Residential mortgage lending is generally sensitive to regional and local economic conditions that significantly impact the ability of borrowers to meet their loan payment obligations, making loss levels difficult to predict. If borrowers are unable to meet their loan repayment obligations, our results of operations would be materially and adversely affected. In addition, a decline in residential real estate values as a result of a downturn in the markets we serve would reduce the value of the real estate collateral securing these types of loans. Declines in real estate values could cause some of our residential mortgages to be inadequately collateralized, which would expose us to a great risk of loss if we seek to recover on defaulted loans by selling the real estate collateral.

Strong competition within our market areas or with respect to our products may limit our growth and profitability.

        Competition in the banking and financial services industry is intense. In our market area, we compete with commercial banks, savings institutions, mortgage brokerage firms, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking firms and unregulated or less regulated non-banking entities, operating locally and elsewhere. Many of these competitors have substantially greater resources and higher lending limits than we have and offer certain services that we do not or cannot provide. In addition, some of our competitors offer loans with lower interest rates on more attractive terms than loans we offer. Competition also makes it increasingly difficult and costly to attract and retain qualified employees. Our profitability depends upon our continued ability to successfully compete in our market areas. If we must raise interest rates paid on deposits or lower interest rates charged on our loans, our net interest margin and profitability could be adversely affected. As we expand into new market areas, we expect that competition for customers and relationships will be intense. As a result, our ability to successfully deploy our business strategy in these market areas may be difficult.

18

Table of Contents

        In addition, we believe that we have historically faced less competition for customers of our Advantage Loan program as compared to the competition we face in the market for qualified mortgages. To the extent that our competitors begin to offer similar products and compete in this area more frequently or intensely, we may face significant pricing pressure. Many of our competitors are much larger and may be able to achieve economies of scale and, as a result, may offer better pricing for the type of products and services we provide. Should competition over the type of loans we underwrite increase, our profitability could be materially and adversely affected. See "Business—Competition."

A lack of liquidity could adversely affect our financial condition and results of operations and result in regulatory limits being placed on the Company.

        Liquidity is essential to our business. We rely on our ability to generate deposits and effectively manage the repayment and maturity schedules of our loans to ensure that we have adequate liquidity to fund our operations. An inability to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect on our liquidity. Our most important source of funds is deposits. Deposit balances can decrease when customers perceive alternative investments as providing a better risk/return tradeoff. If customers move money out of deposits such as money market funds, we would lose a relatively low-cost source of funds, increasing our funding costs and reducing our net interest income and net income. While we strive to appropriately balance our loan to deposit ratio, the growth in our loan portfolio challenges our ability to achieve the optimal ratio.

        Other primary sources of funds consist of cash flows from operations and sales of investment securities, and proceeds from the issuance and sale of our equity securities, including, most recently, net proceeds of approximately $85.5 million from our recent initial public offering. Additional liquidity is provided by our ability to borrow from the Federal Home Loan Bank of Indianapolis (the "FHLB") or our ability to sell portions of our loan portfolio. We also may borrow funds from third-party lenders, such as other financial institutions. Our access to funding sources in amounts adequate to finance or capitalize our activities, or on terms that are acceptable to us, could be impaired by factors that affect us directly or the financial services industry or economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry. Our access to funding sources could also be affected by a decrease in the ability to sell mortgage portfolios as a result of a downturn in our markets or by one or more adverse regulatory actions against us. A lack of liquidity could also attract increased regulatory scrutiny and potential restraints imposed on us by regulators.

        Any decline in available funding could adversely impact our ability to originate loans, invest in securities, meet our expenses, or to fulfill obligations such as repaying our borrowings or meeting deposit withdrawal demands, any of which could have a material adverse impact on our liquidity, business, financial condition and results of operations.

We face significant operational risks because the financial services business involves a high volume of transactions and increased reliance on technology, including risk of loss related to cybersecurity breaches.

        We operate in diverse markets and rely on the ability of our employees and systems to process a high number of transactions and to collect, process, transmit and store significant amounts of confidential information regarding our customers, employees and others, as well as our own business, operations, plans and strategies. Operational risk is the risk of loss resulting from our operations, including but not limited to, the risk of fraud by employees or persons outside our company, the execution of unauthorized transactions, errors relating to transaction processing and technology, systems failures or interruptions, breaches of our internal control systems and compliance requirements, and business continuation and disaster recovery. We face an increasing number of regulations and regulatory scrutiny related to our information technology systems, and security or privacy breaches with respect to our data could result in regulatory fines, reputational harm and customer losses, any of

which would significantly impact our financial condition. Insurance coverage may not be available for such losses, or where available, such losses may exceed insurance limits. In addition, because we perform our own core processing and other technological functions, we cannot rely on indemnification or another source of third-party recovery in the event of a breach of such functions.

        This risk of loss also includes the potential legal actions that could arise as a result of operational deficiencies or as a result of non-compliance with applicable regulatory standards or customer attrition due to potential negative publicity. In addition, we outsource some of our data processing to certain third-party providers. If these third-party providers encounter difficulties, including as a result of cyber-attacks or information security breaches, or if we have difficulty communicating with them, our ability to adequately process and account for transactions could be affected, and our business operations could be materially and adversely affected.

        In the event of a breakdown in our internal control systems, improper operation of systems or improper employee actions, or a breach of our security systems, including if confidential or proprietary information were to be mishandled, misused or lost, we could suffer financial loss, face regulatory action, fines, civil litigation and/or suffer damage to our reputation.

We rely on external financing to fund our operations and the failure to obtain such financing on favorable terms, or at all, in the future could materially and adversely impact our growth strategy and prospects.

        We rely in part on advances from the FHLB to fund our operations. Although we consider such sources of funds adequate for our current needs, we may need to seek additional debt or equity capital in the future to implement our growth strategy in the event that our borrowing availability with the FHLB is decreased. The sale of equity or equity-related securities in the future may be dilutive to our shareholders, and debt financing arrangements may require us to pledge some of our assets and enter into various affirmative and negative covenants, including limitations on operational activities and financing alternatives. Future financing sources, if sought, might be unavailable to us or, if available, could be on terms unfavorable to us and may require regulatory approval. If financing sources are unavailable or are not available on favorable terms or we are unable to obtain regulatory approval, our growth strategy and future prospects could be materially and adversely impacted.

Our ability to originate loans could be restricted by federal regulations and we could be subject to statutory claims for violations of the ability to repay standard.

        The Consumer Financial Protection Bureau has issued a rule intended to clarify how lenders can avoid legal liability under the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act"), which holds lenders accountable for ensuring a borrower's ability to repay a mortgage loan. Under the rule, loans that meet the "qualified mortgage" definition will be presumed to have complied with the new ability-to-repay standard. Under the rule, a "qualified mortgage" loan must not contain certain specified features, including:

•

excessive upfront points and fees (those generally exceeding 3% of the total loan amount, less "bona fide discount points" for prime loans);



•

interest-only payments;



•

negative amortization; and



•

terms of longer than 30 years.

Also, to qualify as a "qualified mortgage," a loan must be made to a borrower whose total monthly debt-to-income ratio does not exceed 43%. Lenders must also verify and document the income and financial resources relied upon to qualify a borrower for the loan and underwrite the loan based on a fully amortizing payment schedule and maximum interest rate during the first five years, taking into account all applicable taxes, insurance and assessments. Lenders of mortgages that meet the "qualified mortgage" standards have a safe harbor or a presumption of compliance with these requirements. A

majority of our residential mortgage loans are not "qualified mortgages," as our underwriting process does not strictly follow applicable regulatory guidance required for such qualification and the rates offered exceed qualifying guidelines. In the event that these mortgages begin to experience a significant rate of default, we could be subject to statutory claims for violations of the ability to repay standard. Any such claims could materially and adversely affect our ability to underwrite these loans, our business, and results of operations or financial condition.

As a business operating in the financial services industry, our business and operations may be adversely affected in numerous and complex ways by weak economic conditions.

        Our business and operations, which primarily consist of lending money to customers in the form of loans, borrowing money from customers in the form of deposits and investing in securities, are sensitive to general business and economic conditions in the United States. If the U.S. economy weakens, our growth and profitability from our lending, deposit and investment operations could be constrained. Uncertainty about the federal fiscal policymaking process, the medium and long-term fiscal outlook of the federal government, and future tax rates is a concern for businesses, consumers and investors in the United States. In addition, economic conditions in foreign countries, including uncertainty over the stability of the euro currency, could affect the stability of global financial markets, which could hinder U.S. economic growth. Weak economic conditions are characterized by deflation, fluctuations in debt and equity capital markets, a lack of liquidity and/or depressed prices in the secondary market for mortgage loans, increased delinquencies on mortgage, consumer and commercial loans, residential and commercial real estate price declines and lower home sales and commercial activity. The current economic environment is also characterized by interest rates at historically low levels, which impacts our ability to attract deposits and to generate attractive earnings through our investment portfolio. All of these factors are detrimental to our business, and the interplay between these factors can be complex and unpredictable. Our business is also significantly affected by monetary and related policies of the U.S. federal government and its agencies. Changes in any of these policies are influenced by macroeconomic conditions and other factors that are beyond our control. Adverse economic conditions and government policy responses to such conditions could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our business is affected by changes in the state of the general economy and the financial markets, and a slowdown or downturn in the general economy or the financial markets could adversely affect our results of operations.

        Our customer activity is intrinsically linked to the health of the economy generally and of the financial markets specifically. In addition to the economic factors discussed above, a downturn in the real estate or commercial markets generally could cause our customers and potential customers to exit the market for real estate or commercial loans. As a result, we believe that fluctuations, disruptions, instability or downturns in the general economy and the financial markets could disproportionately affect demand for our residential and commercial loan services. If such conditions occur and persist, our business and financial results, including our liquidity and our ability to fulfill our debt obligations, could be materially adversely affected.

If the allowance for loan losses is not sufficient to cover actual loan losses, earnings could decrease.

        Loan customers may not repay their loans according to the terms of their loans, and the collateral securing the payment of their loans may be insufficient to assure repayment. We may experience significant credit losses, which could have a material adverse effect on our operating results. Various assumptions and judgments about the collectability of the loan portfolio are made, including the creditworthiness of borrowers and the value of the real estate and other assets serving as collateral for the repayment of many loans. In determining the amount of the allowance for loan losses, management reviews the loans and the loss and delinquency experience and evaluates economic conditions.

21

Table of Contents

        At December 31, 2017, our allowance for loan losses as a percentage of total loans, net of unearned income, was 0.71%. The determination of the appropriate level of allowance is subject to judgment and requires us to make significant estimates of current credit risks and future trends, all of which are subject to material changes. If assumptions prove to be incorrect, the allowance for loan losses may not cover incurred losses in the loan portfolio at the date of the financial statements. Significant additions to the allowance would materially decrease net income. Nonperforming loans may increase and nonperforming or delinquent loans may adversely affect future performance. In addition, federal regulators periodically review the allowance for loan losses and may require an increase in the allowance for loan losses or the recognition of further loan charge offs. Any significant increase in our allowance for loan losses or loan charge offs as required by these regulatory agencies could have a material adverse effect on our results of operations and financial condition.

Changes in economic conditions could cause an increase in delinquencies and nonperforming assets, including loan charge offs, which could depress our net income and growth.

        Our loan portfolio includes primarily real estate secured loans, demand for which may decrease during economic downturns as a result of, among other things, an increase in unemployment, a decrease in real estate values and a slowdown in housing. If we see negative economic conditions develop in the United States as a whole or in the markets that we serve, we could experience higher delinquencies and loan charge offs, which would reduce our net income and adversely affect our financial condition. Furthermore, to the extent that real estate collateral is obtained through foreclosure, the costs of holding and marketing the real estate collateral, as well as the ultimate values obtained from disposition, could reduce our earnings and adversely affect our financial condition.

Because we intend to continue to increase our commercial loans, our credit risk may increase in our commercial loan portfolios.

        At December 31, 2017, our commercial loans totaled $480.1 million, or 18% of our total loans. We intend to increase our originations of commercial loans, within permissible limits for a federal savings bank, which primarily consists of commercial real estate, construction and development, business loans, and commercial lines of credit. These loans generally have more risk than residential mortgage loans.

        Because we plan to continue to increase our originations of these loans, commercial loans generally have a larger average size as compared with other loans such as residential loans. The collateral for commercial loans is generally less readily-marketable and losses incurred on a small number of commercial loans could have a disproportionate and material adverse impact on our financial condition and results of operations.

Interest rate shifts may reduce net interest income and otherwise negatively impact our financial condition and results of operations.

        The majority of our banking assets are monetary in nature and subject to risk from changes in interest rates. Like most financial institutions, our earnings and cash flows depend to a great extent upon the level of our net interest income, or the difference between the interest income we earn on loans, investments and other interest earning assets, and the interest we pay on interest-bearing liabilities, such as deposits and borrowings. Changes in interest rates can increase or decrease our net interest income, because different types of assets and liabilities may react differently, and at different times, to market interest rate changes.

        When interest-bearing liabilities mature or reprice more quickly, or to a greater degree than interest earning assets in a period, an increase in interest rates could reduce net interest income. Similarly, when interest earning assets mature or reprice more quickly, or to a greater degree than interest-bearing liabilities, falling interest rates could reduce net interest income. Additionally, an increase in interest rates may, among other things, reduce the demand for loans and our ability to

22

Table of Contents

originate loans and decrease loan repayment rates. A decrease in the general level of interest rates may affect us through, among other things, increased prepayments on our loan portfolio. Accordingly, changes in the level of market interest rates affect our net yield on interest earning assets, loan origination volume and our overall results. Although our asset-liability management strategy is designed to control and mitigate exposure to the risks related to changes in market interest rates, those rates are affected by many factors outside of our control, including governmental monetary policies, inflation, deflation, recession, changes in unemployment, the money supply, international disorder and instability in domestic and foreign financial markets.

Future changes in interest rates could reduce our profits and asset values.

        Net interest income makes up a majority of our income and is based on the difference between:

•

the interest income we earn on interest earning assets, such as loans and securities; and



•

the interest expense we pay on interest-bearing liabilities, such as deposits and borrowings.

        The rates we earn on our assets and the rates we pay on our liabilities are generally fixed for a contractual period of time. Like many savings institutions, our liabilities generally have shorter contractual maturities than our assets. This imbalance can create significant earnings volatility because market interest rates change over time. In a period of rising interest rates, the demand for our residential lending products may decline and the interest income we earn on our assets may not increase as rapidly as the interest we pay on our liabilities. In a period of declining interest rates, the interest income we earn on our assets may decrease more rapidly than the interest we pay on our liabilities, as borrowers prepay mortgage loans, and mortgage-backed securities and callable investment securities are called, requiring us to reinvest those cash flows at lower interest rates. Such changes in interest rates could materially and adversely affect our results of operations and overall profitability.

        In addition, changes in interest rates can affect the average life of loans and mortgage-backed and related securities. A decline in interest rates results in increased prepayments of loans and mortgage-backed and related securities as borrowers refinance their debt to reduce their borrowing costs. This creates reinvestment risk, which is the risk that we may not be able to reinvest prepayments at rates that are comparable to the rates we earned on the prepaid loans or securities. Furthermore, an inverted interest rate yield curve, where short-term interest rates (which are usually the rates at which financial institutions borrow funds) are higher than long-term interest rates (which are usually the rates at which financial institutions lend funds for fixed-rate loans) can reduce our net interest margin and create financial risk for financial institutions like ours.

A continuation of the historically low interest rate environment and the possibility that we may access higher-cost funds to support our loan growth and operations may adversely affect our net interest income and profitability.

        In recent years the Federal Reserve Board's policy has been to maintain interest rates at historically low levels through its targeted federal funds rate and the purchase of mortgage-backed securities. Recently, the Federal Reserve Board has indicated that it believes a gradual increase in the targeted federal funds rate is appropriate. To this end, the Federal Reserve Board raised the targeted federal funds rate in December 2016 and March, June and December 2017. We cannot make any representation as to whether, or how many times, the Federal Reserve will increase the targeted federal funds rate in the future. Notwithstanding the Federal Reserve Board's expressed intentions, our ability to reduce our interest expense may be limited at current interest rate levels while the average yield on our interest-earning assets may continue to decrease, and our interest expense may increase as we access non-core funding sources or increase deposit rates to fund our operations. A continuation of a low, or relatively low, interest rate environment or increasing our cost of funds may adversely affect our net interest income, which would have a material adverse effect on our profitability.

A substantial majority of our loans and operations are in San Francisco, and therefore our business is particularly vulnerable to a downturn in the San Francisco economy.

        Unlike larger financial institutions that are more geographically diversified, a large portion of our business is concentrated primarily in the state of California, specifically in the San Francisco Bay Area. As of December 31, 2017, 96% of our loan portfolio was based in California and our loan portfolio had concentrations of 67% in the San Francisco Bay Area. While there is not a single employer or industry in our market area on which a significant number of our customers are dependent, if the local economy, and particularly the real estate market, declines, the rates of delinquencies, defaults, foreclosures, bankruptcies and losses in our loan portfolio would likely increase. Similarly, catastrophic natural events such as earthquakes could have a disproportionate effect on our financial condition. As a result of this lack of diversification in our loan portfolio, a downturn in the local economy generally and real estate market specifically could significantly reduce our profitability and growth and have a material adverse effect on our financial condition.

We may not be able to grow, and, if we do grow, we may have difficulty managing that growth.

        Our business strategy is to continue to grow our assets and expand our operations, including through geographic expansion. Our ability to grow depends, in part, upon our ability to expand our market share, successfully attract core deposits, and to identify loan and investment opportunities as well as opportunities to generate fee-based income. We can provide no assurance that we will be successful in increasing the volume of our loans and deposits at acceptable levels and upon terms acceptable to us. We also can provide no assurance that we will be successful in expanding our operations organically or geographically while managing the costs and implementation risks associated with this growth strategy.

We face strong competition in the banking industry, and we may not be able to successfully grow or retain market share in our existing markets.

        We face intense competition in the banking industry from many competitors who compete with us on an international, regional or local level. Our strategy for future growth relies in part on growth in the communities we serve and our ability to develop relationships in particular locations, and we expect to continue to face strong competition from competitors in all of our markets. If we fail to compete effectively against our competitors, we may be unable to expand our market share in our existing markets, and we may be unable to retain our existing market share in key growth markets or in those markets in which we have traditionally had a strong presence. Failure to protect our market share on a regional level or to grow our market share in key growth markets and product categories could have a material adverse effect on our overall market share and on our profitability.

Our business strategy includes growth, and our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively. Growing our operations could also cause our expenses to increase faster than our revenues.

        Our business strategy includes growth in assets, deposits, the scale of our operations and entry into new markets. Achieving such growth will require us to attract customers that currently bank at other financial institutions in our market area and obtain new customers in new market areas where we will have to establish brand recognition and operations. Our ability to successfully grow will depend on a variety of factors, including our ability to attract and retain experienced bankers and loan officers, the continued availability of desirable business opportunities, competition from other financial institutions in our market areas and our ability to manage our growth. Growth opportunities may not be available, may be prohibitively expensive, or we may not be able to manage our growth successfully. If we do not manage our growth effectively, our financial condition and operating results could be negatively affected. Furthermore, there can be considerable costs involved in expanding deposit and lending capacity that generally require a period of time to generate the necessary revenues to offset their costs,

especially in areas in which we do not have an established presence and require alternative delivery methods. Accordingly, any such business expansion can be expected to negatively impact our earnings for some period of time until certain economies of scale are reached. Our expenses could be further increased if we encounter delays in opening new branches.

We may have difficulty identifying additional regional and local markets for expansion of our business, and we may misjudge the potential of new markets.

        In order to successfully expand our business, we must identify new regional and local markets in which we will be successful. To execute this strategy, we must devote substantial financial resources and managerial time to the analysis of demographics, results of competing banks, potential operating costs, real estate costs and availability, construction costs and discretionary spending patterns in different regions of the United States and specific local areas within those selected regions. We may be unfamiliar with many of these areas, and, despite our research, we may choose markets that may prove to be less accepting of our banking concepts than customers in our existing markets. As a result, we may invest substantial time, energy and money in new markets that may not generate satisfactory returns. In addition, new branches, including those located in new markets, will take at least several months to reach planned operating levels due to inefficiencies typically associated with opening a new location, and the financial results of new branches over at least the first year of operation are expected to be below our historical results.

The value of our mortgage servicing rights can be volatile.

        We sell in the secondary market residential mortgage loans that we originate, which provides a meaningful portion of our non-interest income in the form of gains on the sale of mortgage loans. We also earn revenue from fees we receive for servicing mortgage loans. As a result of our mortgage servicing business, we have a growing portfolio of mortgage servicing rights. A mortgage servicing right is the right to service a mortgage loan—collect principal, interest, and escrow amounts—for a fee. We acquire mortgage servicing rights when we keep the servicing rights in connection with the sale of loans we have originated.

        Changes in interest rates may impact our mortgage servicing revenues, which could negatively impact our non-interest income. When rates rise, net revenue from our mortgage servicing activities can increase due to slower prepayments, which reduces our amortization expense for mortgage servicing rights. When rates fall, the value of our mortgage servicing rights usually tends to decline as a result of a higher volume of prepayments, resulting in a decline in our net revenue. It is possible that, because of economic conditions and/or a weak or deteriorating housing market, even if interest rates were to fall or remain low, mortgage originations may also fall or any increase in mortgage originations may not be enough to offset the decrease in the mortgage servicing rights value caused by the lower rates. Because the value of our mortgage servicing rights is capitalized on our balance sheet and evaluated on a quarterly basis, any significant decline in value could adversely affect our income, our capital ratios or require us to raise additional capital, which may not be available on favorable terms.

One of our historical markets, minority and immigrant individuals, may be threatened by gentrification or adverse political developments, which could decrease our growth and profitability.

        We believe that a significant part of our historical strength has been our focus on the minority and immigrant markets. The continuing displacement of minorities due to gentrification of our communities may adversely affect us unless we are able to adapt and increase the acceptance of our products and services by non-minority customers. We may also be unfavorably impacted by political developments adverse to the United States and specifically adverse to markets that are dependent on immigrant populations.

We rely heavily on our management team and our business could be adversely affected by the unexpected loss of one or more of our officers or directors.

        We are led by a management team with substantial experience in the markets that we serve and the financial products that we offer. Our operating strategy focuses on providing products and services through long-term relationship managers. Accordingly, our success depends in large part on the performance of our key officers and directors, as well as on our ability to attract, motivate and retain highly qualified senior and middle management. Competition for employees is intense, and the process of identifying key personnel with the combination of skills and attributes required to execute our business plan may be lengthy. We may not be successful in retaining our key employees or directors and the unexpected loss of services of one or more of our officers or directors could have a material adverse effect on our business because of their skills, knowledge of our market and financial products, years of industry experience, long-term business and customer relationships and the difficulty of finding qualified replacement personnel. If the services of any of our key personnel should become unavailable for any reason, we may not be able to identify and hire qualified persons on terms acceptable to us, which could have a material adverse effect on our business, financial condition and results of operations.

We may be at risk for future restrictions on compensation paid to our executives.

        As a private closely held company, we have historically not been subject to compensation restrictions. Under certain circumstances, our primary regulators could impose restrictions on compensation to our management team. In addition, as a public company, we are required to disclose the compensation of our named executive officers and may face pressure from investors to the extent such compensation is deemed excessive. If we experience future limitations in our executive compensation program, these limitations may make it more difficult to attract and retain executive officers.

Our future success depends on our ability to retain key executives and to identify, attract, retain and motivate qualified personnel.

        We are highly dependent on the experience and strong relationships we have developed in the communities that we serve. We also recognize that the banking industry is competitive and should we lose several of our front office personnel, it would take time for new employees to develop the experience and cultural values that we believe our long-term employees have developed. Additionally, our hiring processes are unique to us, meaning that we prefer to hire employees with experience in our industry and who have an interest in working with the Bank for many years. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully manage, develop and grow in the banking industry. If we fail to identify and develop or recruit successors, we are at risk of being harmed by the departures of key employees.

The success of our growth strategy depends on our ability to identify and retain individuals with experience and relationships in the markets in which we intend to expand.

        We may expand our banking network over the next several years, not just in our existing and planned market areas, but also in other communities. To expand into new markets successfully, we must identify and retain experienced key management members with local expertise and relationships in these markets. We expect that competition for qualified management in the markets in which we may expand will be intense and that there will be a limited number of qualified persons with knowledge of and experience in the community banking industry in these markets. Even if we identify individuals that we believe could assist us in establishing a presence in a new market, we may be unable to recruit these individuals away from competitors or more established banks. In addition, the process of identifying and recruiting individuals with the combination of skills and attributes required to carry out our

26

Table of Contents

strategy is often lengthy. Our inability to identify, recruit, and retain talented personnel to manage new banking offices effectively would limit our growth and could materially and adversely affect our business, financial condition, and results of operations.

We are subject to certain operational risks, including, but not limited to, customer, third party, or employee fraud and data processing system failures and errors.

        Employee errors and employee and customer misconduct could subject us to financial losses or regulatory sanctions and seriously harm our reputation. Misconduct by our employees could include hiding unauthorized activities from us, improper or unauthorized activities on behalf of our customers or improper use of confidential information. It is not always possible to prevent employee errors and misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. Employee errors could also subject us to financial claims for negligence and increased regulatory scrutiny.

        We maintain a system of internal controls and insurance coverage to mitigate against operational risks, including data processing system failures and errors and customer or employee fraud. If our internal controls fail to prevent or detect an occurrence, or if any resulting loss is not insured or exceeds applicable insurance limits, it could have a material adverse effect on our business, financial condition and results of operations.

We depend on the accuracy and completeness of information provided by customers and counterparties.

        In deciding whether to extend credit or enter into other transactions with customers and counterparties, we may rely on information furnished to us by, or on behalf of, customers and counterparties, including financial statements and other financial information. We also may rely on representations of customers and counterparties as to the accuracy and completeness of that information. In deciding whether to extend credit, we may rely upon our customers' representations that their financial statements are accurate. We also may rely on customer representations and certifications, or other audit or accountants' reports, with respect to the business and financial condition of our commercial clients. Our financial condition, results of operations, financial reporting and reputation could be materially adversely affected if we rely on materially misleading, false, inaccurate or fraudulent information.

We may incur future losses in connection with certain representations and warranties we've made with respect to mortgages that we have sold into the secondary market.

        From time to time, we package residential mortgages for sale into the secondary market. In connection with such sales, we make representations and warranties, which, if breached, may require us to repurchase such loans, substitute other loans or indemnify the purchasers of such loans for actual losses incurred in respect of such loans. A substantial decline in residential real estate values in the markets in which we originated such loans could increase the risk of such consequences. While we have not to date received any repurchase requests and we currently believe our repurchase risk remains low based upon our careful loan underwriting and documentation standards, it is possible that requests to repurchase loans could occur in the future and such requests may have a negative financial impact on us.

We are a community bank and our ability to maintain our reputation is critical to the success of our business and the failure to do so may materially adversely affect our performance.

        We are a community bank, and our reputation is one of the most valuable components of our business. A key component of our business strategy is to rely on our reputation for customer service and knowledge of local markets to expand our presence by capturing new business opportunities from existing and prospective customers in our market area and new market areas. As such, we strive to

27

---

Table of Contents

conduct our business in a manner that enhances our reputation. This is done, in part, by recruiting, hiring and retaining employees who share our core values of being an integral part of the communities we serve, delivering superior service to our customers and caring about our customers and associates. If our reputation is negatively affected by the actions of our employees, by our inability to conduct our operations in a manner that is appealing to current or prospective customers, or otherwise, our business and, therefore, our operating results may be materially adversely affected.

If our enterprise risk management framework is not effective at mitigating risk and loss to us, we could suffer unexpected losses and our results of operations could be materially adversely affected.

        Our enterprise risk management framework seeks to achieve an appropriate balance between risk and return, which is critical to optimizing shareholder value. We have established processes and procedures intended to identify, measure, monitor, report and analyze the types of risk to which we are subject, including credit, liquidity, operational, regulatory compliance and reputational. However, as with any risk management framework, there are inherent limitations to our risk management strategies as there may exist, or develop in the future, risks that we have not appropriately anticipated or identified. If our risk management framework proves ineffective, we could suffer unexpected losses and our business and results of operations could be materially adversely affected.

Our modest size makes it more difficult for us to compete.

        Our modest size makes it more difficult to compete with other financial institutions which are generally larger and can more easily afford to invest in the marketing and technologies needed to attract and retain customers. Because our principal source of income is the net interest income we earn on our loans and investments after deducting interest paid on deposits and other sources of funds, our ability to generate the revenues needed to cover our expenses and finance such investments is limited by the size of our loan and investment portfolios. Accordingly, we are not always able to offer new products and services as quickly as our competitors. As a smaller institution, we are also disproportionately affected by the continually increasing costs of compliance with new banking and other regulations.

We face risks related to our operational, technological and organizational infrastructure.

        Our ability to grow and compete is dependent on our ability to build or acquire the necessary operational and technological infrastructure and to manage the cost of that infrastructure as we expand. Similar to other corporations, operational risk can manifest itself in many ways, such as errors related to failed or inadequate processes, faulty or disabled computer systems, fraud by employees or outside persons and exposure to external events. As discussed below, we are dependent on our operational infrastructure to help manage these risks. In addition, we are heavily dependent on the strength and capability of our technology systems which we use both to interface with our customers and to manage our internal financial records and other systems. Our ability to develop and deliver new products that meet the needs of our existing customers and attract new ones depends on the functionality of our technology systems. Additionally, our ability to run our business in compliance with applicable laws and regulations is dependent on these infrastructures.

        We monitor our operational and technological capabilities and make modifications and improvements when we believe it will be cost effective to do so. In some instances, we may build and maintain these capabilities ourselves. Specifically, we provide our own core systems processing and essential web hosting. We also outsource some of these functions to third parties. If we experience difficulties, fail to comply with banking regulations or keep up with increasingly sophisticated technologies, our operations could be interrupted. If an interruption were to continue for a significant period of time, our business, financial condition and results of operations could be adversely affected, perhaps materially. Even if we are able to replace them, it may be at a higher cost to us, which could materially adversely affect our business, financial condition and results of operations.

Adherence to our internal policies and procedures by our employees is critical to our performance and how we are perceived by our regulators.

        Our internal policies and procedures are a critical component of our corporate governance and, in some cases, compliance with applicable regulations. We adopt internal policies and procedures to guide management and employees regarding the operation and conduct of our business. Any deviation or non-adherence to these internal policies and procedures, whether intentional or unintentional, could have a detrimental effect on our management, operations or financial condition.

We must keep pace with technological change to remain competitive and introduce new products and services.

        Financial products and services have become increasingly technologically driven. Our ability to meet the needs of our customers competitively and introduce new products in a cost-efficient manner is dependent on the ability to keep pace with technological advances, to invest in new technology as it becomes available, and to obtain and maintain related essential personnel. Many of our competitors have already implemented critical technologies and have greater resources to invest in technology than we do and may be better equipped to market new technologically driven products and services. In addition, we may not have the same ability to rapidly respond to technological innovations as our competitors do. Furthermore, the introduction of new technologies and products by financial technology companies and "fintech" platforms may adversely affect our ability to obtain new customers and successfully grow our business. The ability to keep pace with technological change is important, and the failure to do so, due to cost, proficiency or otherwise, could have a material adverse impact on our business and therefore on our financial condition and results of operations.

Changes in accounting standards could materially impact our financial statements.

        From time to time, the Financial Accounting Standards Board or the SEC may change the financial accounting and reporting standards that govern the preparation of our financial statements. Such changes may result in us being subject to new or changing accounting and reporting standards. In addition, the bodies that interpret the accounting standards (such as banking regulators, outside auditors or management) may change their interpretations or positions on how these standards should be applied. These changes may be beyond our control, can be hard to predict, and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retrospectively, or apply an existing standard differently, also retrospectively, in each case resulting in our needing to revise or restate prior period financial statements.

Adverse conditions internationally could adversely affect our business.

        Many of our customers are recent immigrants or foreign nationals. U.S. and global economic policies, military tensions, and unfavorable global economic conditions may adversely impact the economies in which our customers have family or business ties. A significant deterioration of economic conditions internationally, and in Asia in particular, could expose us to, among other things, economic and transfer risk, and we could experience an outflow of deposits by those of our customers with connections to Asia. In addition, foreign currency restrictions, particularly on the movement of cash from abroad, could adversely affect many of our customers, including with respect to their ability to make down payments or repay loans. Adverse economic conditions abroad, and in China or Taiwan in particular, may also negatively impact asset values and the profitability and liquidity of our customers with ties to these regions.

Changes in the valuation of our securities portfolio could hurt our profits and reduce our shareholders' equity.

        Our securities portfolio may be impacted by fluctuations in market value, potentially reducing accumulated other comprehensive income and/or earnings. Fluctuations in market value may be caused

by changes in market interest rates, lower market prices for securities and limited investor demand. Management evaluates securities for other-than-temporary impairment on a quarterly basis, with more frequent evaluation for selected issues. In analyzing a debt issuer's financial condition, management may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred and industry analysts' reports. In analyzing an equity issuer's financial condition, management may consider industry analysts' reports, financial performance and projected target prices of investment analysts. If this evaluation shows impairment to the actual or projected cash flows associated with one or more securities, a potential loss to earnings may occur. Changes in interest rates can also have an adverse effect on our financial condition, as our available-for-sale securities are reported at their estimated fair value, and therefore are impacted by fluctuations in interest rates. We increase or decrease our shareholders' equity by the amount of change in the estimated fair value of the available-for-sale securities, net of taxes. Declines in market value could result in other-than-temporary impairments of these assets, which would lead to accounting charges that could have a material adverse effect on our net income and capital levels. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Securities Portfolio."

Legal and regulatory proceedings and related matters could adversely affect us.

        We have been, and may in the future become, involved in legal and regulatory proceedings. We consider most of the proceedings to be in the normal course of our business or typical for the industry; however, it is inherently difficult to assess the outcome of these matters, and we may not prevail in any proceedings or litigation. There could be substantial cost and management diversion in such litigation and proceedings, and any adverse determination could have a material adverse effect on our business, brand or image, or our financial condition and results of our operations.

As part of our asset/liability management strategy, we sell portions of our residential loan portfolio from time to time, while retaining servicing rights. If the market for our mortgage loans to the secondary market were to significantly contract, our earnings profile would be negatively affected and our ability to manage our balance sheet would be materially and adversely affected.

        From time to time, we manage our liquidity and balance sheet risk by selling loans in our mortgage portfolio into the secondary market. If the market for our mortgages were to contract or our counterparties were to lose confidence in our asset quality, we would lose a key piece of our liquidity strategy and would need to find alternative means to manage our liquidity that may be less effective. If the market for our residential portfolio were to contract, our liquidity, capital ratios and financial condition would be materially and adversely affected.

Any debt service obligations will reduce the funds available for other business purposes, and the terms and covenants relating to our current and future indebtedness could adversely impact our financial performance and liquidity.

        We have sold $65 million in aggregate principal amount of our 7.0% Fixed to Floating Subordinated Notes due April 15, 2026. As a result, we are currently, and to the extent we incur significant debt in the future, we will be, subject to risks typically associated with debt financing, such as insufficient cash flow to meet required debt service payment obligations and the inability to refinance existing indebtedness. In addition, our subordinated notes and the related subordinated note purchase agreements contain customary covenants, which under certain circumstances place restrictions on our ability to pay dividends or make other distributions and enter into certain transactions, including acquisition activity. If we fail to satisfy one or more of the covenants under our subordinated notes, we would be in default under such notes, and may be required to repay such debt with capital from other sources. Under such circumstances, other sources of capital may not be available to us on reasonable terms or at all.

We and our borrowers in our California communities may be adversely affected by earthquakes or other natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

        The majority of our branches are located in the San Francisco and Los Angeles, California areas, which in the past have experienced both severe earthquakes and wildfires. We do not carry earthquake insurance on our properties. Earthquakes, wildfires or other natural disasters could severely disrupt our operations, and have a material adverse effect on our business, results of operations, financial condition and prospects. In addition, our customers and loan collateral may be severely impacted by such events, resulting in losses.

        If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our branches, that damaged critical infrastructure or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time in the San Francisco and/or Los Angeles, California areas. The disaster recovery and business continuity plans we have in place currently are limited and are unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

Risks Related to Our Industry and Regulation

Our business, financial condition, results of operations and future prospects could be adversely affected by the highly regulated environment and the laws and regulations that govern our operations, corporate governance, executive compensation and accounting principles, or changes in any of them.

        As a unitary thrift holding company, we are subject to extensive examination, supervision and comprehensive regulation by various federal agencies that govern almost all aspects of our operations. These laws and regulations are not intended to protect our shareholders. Rather, these laws and regulations are intended to protect customers, depositors, the Deposit Insurance Fund (the "DIF") and the overall financial stability of the United States. These laws and regulations, among other matters, prescribe minimum capital requirements, impose limitations on the business activities in which we can engage, limit the dividend or distributions that Sterling Bank can pay to us, restrict the ability of institutions to guarantee our debt, and impose certain specific accounting requirements on us that may be more restrictive and may result in greater or earlier charges to earnings or reductions in our capital than generally accepted accounting principles would require. Compliance with these laws and regulations is difficult and costly, and changes to these laws and regulations often impose additional compliance costs. Our failure to comply with these laws and regulations, even if the failure follows good faith effort or reflects a difference in interpretation, could subject us to restrictions on our business activities, fines and other penalties, any of which could materially adversely affect our results of operations, capital base and the price of our securities. Further, any new laws, rules and regulations could make compliance more difficult or expensive.

        Likewise, the Company operates in an environment that imposes income taxes on its operations at both the federal and state levels to varying degrees. Changes in tax laws could significantly affect our financial position and results of operations. In addition, we are subject to regular review and audit by U.S. federal and certain state authorities. Tax authorities may disagree with certain positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial position and results of operations.

Legislative and regulatory actions taken now or in the future may increase our costs and impact our business, governance structure, financial condition or results of operations.

        The Dodd-Frank Act, among other things, imposed new capital requirements on thrift holding companies; changed the base for FDIC insurance assessments to a bank's average consolidated total assets minus average tangible equity, rather than upon its deposit base; permanently raised the current standard deposit insurance limit to $250,000; and expanded the FDIC's authority to raise insurance premiums. The Dodd-Frank Act also established the Consumer Financial Protection Bureau as an independent entity within the FRB, which has broad rulemaking, supervisory and enforcement authority over consumer financial products and services, including deposit products, residential mortgages, home-equity loans and credit cards and contains provisions on mortgage-related matters, such as steering incentives, determinations as to a borrower's ability to repay and prepayment penalties. Although the applicability of certain elements of the Dodd-Frank Act is limited to institutions with more than $10 billion in assets, there can be no guarantee that such applicability will not be extended in the future or that regulators or other third parties will not seek to impose such requirements on institutions with less than $10 billion in assets, such as the Company. The Dodd-Frank Act has had and may continue to have a material impact on our operations, particularly through increased regulatory burden and compliance costs. Because the FRB has only been a primary regulator for thrift holding companies since 2012, it is unclear whether we will be exposed to additional regulatory burdens. Any future legislative changes could have a material impact on our profitability, the value of assets held for investment or the value of collateral for loans. Future legislative changes could also require changes to business practices and potentially expose us to additional costs, liabilities, enforcement action and reputational risk.

        Compliance with the Dodd-Frank Act and its implementing regulations has and will continue to result in additional operating and compliance costs that could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

        In addition, new proposals for legislation continue to be introduced in the U.S. Congress that could further substantially increase regulation of the bank and non-bank financial services industries and impose restrictions on the operations and general ability of firms within the industry to conduct business consistent with historical practices. Federal regulatory agencies also frequently adopt changes to their regulations or change the manner in which existing regulations are applied. Certain aspects of current or proposed regulatory or legislative changes to laws applicable to the financial industry, if enacted or adopted, may impact the profitability of our business activities, require more oversight or change certain of our business practices, including the ability to offer products, obtain financing, attract deposits, make loans and achieve satisfactory interest spreads and could expose us to additional costs, including increased compliance costs. These changes also may require us to invest significant management attention and resources to make any necessary changes to operations to comply and could have a material adverse effect on our business, financial condition and results of operations.

We face a risk of noncompliance and enforcement action with the Bank Secrecy Act and other anti-money laundering statutes and regulations.

        The Bank Secrecy Act, the USA Patriot Act and other laws and regulations require financial institutions, among other duties, to institute and maintain an effective anti-money laundering program and to file timely reports such as suspicious activity reports and currency transaction reports. We are required to comply with these and other anti-money laundering requirements. The federal banking agencies and Financial Crimes Enforcement Network are authorized to impose significant civil money penalties for violations of those requirements and have recently engaged in coordinated enforcement efforts against banks and other financial services providers with the U.S. Department of Justice, Drug Enforcement Administration and Internal Revenue Service. We are also subject to increased scrutiny of compliance with the rules enforced by the Office of Foreign Assets Control. Because a significant

32

portion of our customer base consists of foreign nationals and recent immigrants, these laws and regulations pose disproportionate challenges to us relative to our peers. If our policies, procedures and systems are deemed deficient, we would be subject to liability, including fines and regulatory actions, which may include restrictions on our ability to pay dividends and the necessity to obtain regulatory approvals to proceed with certain aspects of our business plan.

        Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for us. Any of these results could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We are subject to the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to material penalties.

        The Community Reinvestment Act ("CRA"), the Equal Credit Opportunity Act, the Fair Housing Act and other fair lending laws and regulations impose nondiscriminatory lending requirements on financial institutions. The Consumer Financial Protection Bureau, the United States Department of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful challenge to an institution's performance under the CRA or fair lending laws and regulations could result in a wide variety of sanctions, including the required payment of damages and civil money penalties, injunctive relief, imposition of restrictions on mergers and acquisitions activity and restrictions on expansion activity. Private parties may also have the ability to challenge an institution's performance under fair lending laws in private class action litigation.

Federal regulators periodically examine our business, and we may be required to remediate adverse examination findings.

        The Federal Reserve Board ("FRB") and the Office of the Comptroller of the Currency ("OCC") periodically examine our business, including our compliance with laws and regulations. If, as a result of an examination, a federal banking agency were to determine that our financial condition, capital resources, asset quality, earnings prospects, management, interest rate risk and liquidity or other aspects of any of our operations had become unsatisfactory, or that we were in violation of any law or regulation, it may take a number of different remedial actions as it deems appropriate. These actions include the power to enjoin "unsafe or unsound" practices, to require affirmative action to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in our capital, to restrict our growth, to assess civil monetary penalties against our officers or directors, to remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is an imminent risk of loss to depositors, to terminate our deposit insurance and place us into receivership or conservatorship. If we become subject to any regulatory actions, it could have a material adverse effect on our business, results of operations, financial condition and growth prospects.

As a result of the Dodd-Frank Act and recent rulemaking, we are subject to more stringent capital requirements.

        In July 2013, the U.S. federal banking authorities approved new regulatory capital rules implementing the Basel III regulatory capital reforms effecting certain changes required by the Dodd-Frank Act. The new regulatory capital requirements are generally applicable to all U.S. banks as well as to unitary thrift holding companies with assets over $1 billion, such as the Company. The new regulatory capital rules not only increase most of the required minimum regulatory capital ratios, but also introduce a new common equity Tier 1 capital ratio and the concept of a capital conservation buffer. The new regulatory capital rules also expand the current definition of capital by establishing additional criteria that capital instruments must meet to be considered additional Tier 1 and Tier 2 capital. In order to be a "well-capitalized" depository institution under the new regime, an institution

33

---

Table of Contents

must maintain a common equity Tier 1 capital ratio of 6.5% or more; a Tier 1 capital ratio of 8% or more; a total capital ratio of 10% or more; and a leverage ratio of 5% or more. Institutions must also maintain a capital conservation buffer consisting of common equity Tier 1 capital. The new regulatory capital rules became effective as applied to Sterling Bank on January 1, 2015 with a phase-in period that generally extends through January 1, 2019 for many of the changes. The mechanisms the FRB will utilize to enforce, and the manner in which the FRB will interpret, these standards with respect to unitary thrifts such as the Company remain uncertain.

        The failure to meet applicable regulatory capital requirements could result in one or more of our regulators placing limitations or conditions on our activities, including our growth initiatives, or restricting the commencement of new activities, and could materially adversely affect customer and investor confidence, our costs of funds and FDIC insurance costs, our ability to pay dividends on our common stock, our ability to make acquisitions, and our business, results of operations and financial conditions, generally.

The FRB or OCC may require us to commit capital resources to support Sterling Bank.

        As a matter of policy, the FRB expects a unitary thrift holding company to act as a source of financial and managerial strength for a subsidiary bank and to commit resources to support such subsidiary bank. The Dodd-Frank Act codified the FRB's policy on serving as a source of financial strength. Under the "source of strength" doctrine, the FRB may require a unitary thrift holding company to make capital injections into a troubled subsidiary bank and may charge the unitary thrift holding company with engaging in unsafe and unsound practices for failure to commit resources to a subsidiary bank. A capital injection may be required at times when the holding company may not have the resources to provide it and therefore may be required to borrow the funds or raise capital. Any loans by a holding company to its subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of the subsidiary bank. In the event of a unitary thrift's bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the institution's general unsecured creditors, including the holders of its note obligations. Thus, any borrowing that must be done by the Company to make a required capital injection becomes more difficult and expensive and could have an adverse effect on our business, financial condition and results of operations. The requirement that we serve as a source of strength to our Bank may be exacerbated by OCC requirements to maintain certain capital requirements at the bank level and we may not be able to access the necessary funds to do so, which would further materially adversely affect our business, financial condition and results of operations.

The FASB has recently issued an accounting standard update that will result in a significant change in how we provide for credit losses and may have a material impact on our financial condition or results of operations.

        In June 2016, the Financial Accounting Standards Board issued an accounting standard update, "Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," which replaces the current "incurred loss" model for recognizing credit losses with an "expected loss" model referred to as the Current Expected Credit Loss ("CECL") model. Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the

34

Table of Contents

"incurred loss" model required under U.S. GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. Moreover, the CECL model may create more volatility in the level of our allowance for loan losses. If we are required to materially increase our level of allowance for loan losses for any reason, such increase could adversely affect our business, financial condition and results of operations.

        The new CECL standard will become effective for us for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. We are currently evaluating the impact the CECL model will have on our accounting, but we expect to recognize a one-time cumulative-effect adjustment to our allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, consistent with regulatory expectations set forth in interagency guidance issued at the end of 2016. We cannot yet determine the magnitude of any such one-time cumulative adjustment or of the overall impact of the new standard on our financial condition or results of operations.

FDIC deposit insurance assessments may materially increase in the future, which would have an adverse effect on earnings.

        As a member institution of the FDIC, our subsidiary, Sterling Bank, is assessed a quarterly deposit insurance premium. Failed banks nationwide significantly depleted the insurance fund and reduced the ratio of reserves to insured deposits. The FDIC has adopted a Deposit Insurance Fund Restoration Plan, which requires the FDIC's DIF to attain a 1.35% reserve ratio by September 30, 2020. As a result of this requirement, Sterling Bank could be required to pay significantly higher premiums or additional special assessments that would adversely affect its earnings, thereby reducing the availability of funds to pay dividends to us.

Monetary policies and regulations of the FRB could adversely affect our business, financial condition and results of operations.

        In addition to being affected by general economic conditions, our earnings and growth are affected by the policies of the FRB. An important function of the FRB is to regulate the money supply and credit conditions. Among the instruments used by the FRB to implement these objectives are open market purchases and sales of U.S. government securities, adjustments of the discount rate and changes in banks' reserve requirements against bank deposits. These instruments are used in varying combinations to influence overall economic growth and the distribution of credit, bank loans, investments and deposits. Their use also affects interest rates charged on loans or paid on deposits.

        The monetary policies and regulations of the FRB have had a significant effect on the operating results of banks in the past and are expected to continue to do so in the future. The effects of such policies upon our business, financial condition and results of operations cannot be predicted.

Our accounting estimates and risk management processes and controls rely on analytical and forecasting techniques and models and assumptions, which may not accurately predict future events.

        Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Our management must exercise judgment in selecting and applying many of these accounting policies and methods so they comply with GAAP and reflect management's judgment of the most appropriate manner in which to report our financial condition and results. In some cases, management must select the accounting policy or method to apply from two or more alternatives, any of which may be reasonable under the circumstances, yet which may result in our reporting materially different results than would have been reported under a different alternative.

35

Table of Contents

        Certain accounting policies are critical to presenting our financial condition and results of operations. They require management to make difficult, subjective or complex judgments about matters that are uncertain. Materially different amounts could be reported under different conditions or using different assumptions or estimates. These critical accounting policies include the allowance for loan losses and the fair value of securities. Because of the uncertainty of estimates involved in these matters, we may be required to significantly increase the allowance for loan losses or sustain loan losses that are significantly higher than the reserve provided or reduce the carrying value of an asset measured at fair value. Any of these could have a material adverse effect on our business, financial condition or results of operations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

        Our internal controls, disclosure controls, processes and procedures, and corporate governance policies and procedures are based in part on certain assumptions and can provide only reasonable (not absolute) assurances that the objectives of the system are met. Any failure or circumvention of our controls, processes and procedures or failure to comply with regulations related to controls, processes and procedures could necessitate changes in those controls, processes and procedures, which may increase our compliance costs, divert management attention from our business or subject us to regulatory actions and increased regulatory scrutiny. Any of these could have a material adverse effect on our business, financial condition or results of operations.

We could be adversely affected by the soundness of other financial institutions and other third parties we rely on.

        Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to many different industries and counterparties, and routinely execute transactions with counterparties in the financial services industry, including banks, brokers and dealers, investment banks and other institutional entities. Many of these transactions expose us to credit risk in the event of a default by a counterparty or client. In addition, our credit risk may be exacerbated when our collateral cannot be foreclosed upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure due.

Tax matters, including the changes in corporate tax rates, disagreements with taxing authorities and imposition of new taxes could impact our results of operations and financial condition.

        We are subject to income and other taxes in the U.S. and our operations, plans and results are affected by tax and other initiatives. On December 22, 2017, the Tax Cuts and Jobs Act (H.R. 1) (the "Tax Act") was signed into law by President Trump. The Tax Act contains significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of earnings (except for certain small businesses), limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one-time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the new federal tax law is uncertain and our business and financial condition could be adversely affected. It is also unknown if and to what extent various states will conform to the newly enacted federal tax law. The decrease in the corporate tax rate has resulted in changes in the valuation of our deferred tax assets and liabilities, and may result in future changes. Any such change in valuation could have a material impact on our income tax expense and deferred tax balances.

        We are also subject to regular reviews, examinations, and audits by the Internal Revenue Service and other taxing authorities with respect to our taxes. Although we believe our tax estimates are

36

---

Table of Contents

reasonable, if a taxing authority disagrees with the positions we have taken, we could face additional tax liability, including interest and penalties. There can be no assurance that payment of such additional amounts upon final adjudication of any disputes will not have a material impact on our results of operations and financial position.

Risks Related to Governance Matters

We are a "controlled company" under the corporate governance rules for NASDAQ-listed companies, and we may eventually elect to take advantage of the "controlled company" exception, which would make our common stock less attractive to some investors or otherwise harm our stock price.

        Because we qualify as a "controlled company" under the corporate governance rules for NASDAQ-listed companies, we are not required to have a majority of our board of directors be independent, nor are we required to have a compensation committee or an independent nominating function. In light of our status as a controlled company, our board of directors could determine not to have an independent nominating function and may choose to have the full board of directors be directly responsible for nominating members of our board, and in the future we could elect not to have a majority of our board of directors be independent or not to have a compensation committee. Accordingly, should the interests of our controlling shareholder differ from those of other shareholders, the other shareholders may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance rules for NASDAQ-listed companies. We may take advantage of some or all the "controlled company" exceptions and to the extent we do not, this determination could change in the future. Our status as a controlled company could make our common stock less attractive to some investors or otherwise harm our stock price.

The Seligman family, through the family's trustee and the Bank's founder and the Company's Vice President, Mr. Scott Seligman, have the ability to influence Company operations and control the outcome of matters submitted for shareholder approval and may have interests that differ from those of our other shareholders.

        Certain trusts for the benefit of members of the Seligman family and administered by their trustee or other Seligman family members or their designees beneficially own approximately 67.1% of our common stock. In addition, Scott Seligman, the founder of the Bank, Vice President of the Company and consultant to the Bank's board of directors, represents the interests of the family and continues to serve in an advisory capacity to the Company and the Bank, including through attendance at board meetings and frequent consultation with senior management. Therefore, Mr. Seligman has access and influence with respect to Company operations and the Seligman family trustee have effective control over the outcome of votes on all matters requiring approval by shareholders, including the election of directors, the adoption of amendments to our articles of incorporation and bylaws and approval of a sale of the Company and other significant corporate transactions, regardless of how other shareholders vote on these matters. Furthermore, the interests of the Seligman family may be different than the interests of other shareholders. This concentration of voting power could also have the effect of delaying, deterring or preventing a change in control or other business combination that might otherwise be beneficial to our shareholders.

Certain provisions of our corporate governance documents and Michigan law could discourage, delay or prevent a merger or acquisition at a premium price.

        Our second amended and restated articles of incorporation and amended and restated contain provisions that may make the acquisition of our Company more difficult without the approval of our board of directors. These include provisions that, among other things:

•

permit the board to issue up to 10 million shares of preferred stock, with any rights, preferences and privileges as they may determine (including the right to approve an acquisition or other change in control);

37

---

Table of Contents

•

provide that the authorized number of directors may be fixed only by the board in accordance with our amended and restated bylaws;



•

do not provide for cumulative voting rights (therefore allowing the holders of a majority of the shares entitled to vote in any election of directors to elect all of the directors standing for election);



•

divide our board into three staggered classes;



•

provide that all vacancies and newly created directorships may be filled by the affirmative vote of at least 80% of directors then in office, even if less than a quorum;



•

prohibit removal of directors without cause;



•

prohibit shareholders from calling special meetings of shareholders;



•

require unanimous consent for stockholders to take action by written consent without approval of the action by our board;



•

provide that shareholders seeking to present proposals before a meeting of shareholders or to nominate candidates for election as directors at a meeting of shareholders must provide advance notice in writing and also comply with specified requirements related to the form and content of a shareholder's notice;



•

require at least 80% supermajority shareholder approval to alter, amend or repeal certain provisions of our second amended and restated articles of incorporation; and



•

require at least 80% supermajority shareholder approval in order for shareholders to adopt, amend or repeal our amended and restated bylaws.

        These provisions may frustrate or prevent any attempts by our shareholders to replace or remove our current management by making it more difficult for shareholders to replace members of the board of directors, which is responsible for appointing members of our management. Any matters requiring the approval of our shareholders will require the approval of the Seligman family and their trustee, which may have interests that differ from those of our other shareholders.

        In addition, the 2017 Omnibus Equity Incentive Plan permits the board of directors or a committee thereof to accelerate, vest or cause the restrictions to lapse with respect to outstanding equity awards, in the event of, or immediately prior to, a change in control. Such vesting or acceleration could discourage the acquisition of our Company.

        We could also become subject to certain anti-takeover provisions under Michigan law which may discourage, delay or prevent someone from acquiring us or merging with us, whether or not an acquisition or merger is desired by or beneficial to our shareholders. If a corporation's board of directors chooses to "opt-in" to certain provisions of Michigan Law, such corporation may not, in general, engage in a business combination with any beneficial owner, directly or indirectly, of 10% of the corporation's outstanding voting shares unless the holder has held the shares for five years or more or, among other things, the board of directors has approved the business combination. Our board of directors has not elected to be subject to this provision, but could do so in the future. Any provision of our second amended and restated articles of incorporation or amended and restated bylaws or Michigan law that has the effect of delaying or deterring a change in control could limit the opportunity for our shareholders to receive a premium for their shares, and could also affect the price that some investors are willing to pay for our common stock otherwise.

Our second amended and restated articles of incorporation designates the courts of the State of Michigan located in Oakland County and the United States District for the Eastern District of Michigan as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

        Our second amended and restated articles of incorporation provides that the courts of the State of Michigan located in Oakland County and the United States District for the Eastern District of Michigan shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or employees to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Michigan Business Corporation Act (as it may be amended from time to time, the "MBCA"), or (iv) any action asserting a claim against us governed by the State of Michigan's internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our common stock shall be deemed to have notice of and consented to the provisions of our second amended and restated articles of incorporation described above. This choice of forum provision may limit a shareholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find these provisions of our second amended and restated articles of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

Our ability to pay dividends is restricted by applicable law and the terms of our subordinated notes.

on average tangible common equity and tangible common equity to tangible assets ratio. Our management uses these non-GAAP financial measures in its analysis of our performance.

Return on Average Tangible Common Equity

        Management measures return on average tangible common equity to assess the Company's capital strength and business performance. Average tangible equity excludes the effect of intangible assets. This non-GAAP financial measure should not be considered a substitute for those comparable measures that are similarly titled that are determined in accordance with U.S. GAAP that may be used by other companies. The following table reconciles average shareholders' equity on a U.S. GAAP basis to average tangible common equity to arrive at our return on average tangible common equity:

Tangible Common Equity to Tangible Assets Ratio

        The tangible common equity to tangible assets ratio is a non-GAAP measure that is generally used by financial analysts and investment bankers to evaluate capital adequacy. We calculate (i) tangible common equity as total shareholders' equity less intangible assets and (ii) tangible assets as total assets less intangible assets. This non-GAAP financial measure should not be considered a substitute for those comparable measures that are similarly titled that are determined in accordance with U.S. GAAP that may be used by other companies.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cautionary Note Regarding Forward-Looking Statements

        This Annual Report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as "may," "might," "should," "could," "predict," "potential," "believe," "expect," "attribute," "continue," "will," "anticipate," "seek," "estimate," "intend," "plan," "projection," "goal," "target," "outlook," "aim," "would," "annualized" and "outlook," or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management's beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

        The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements:

•

Our concentration in residential mortgage loans exposes us to risks from certain conditions in our market;



•

Strong competition within our market areas with respect to our products and pricing may limit our growth and profitability;



•

A lack of liquidity could adversely affect our financial condition and results of operations resulting in regulatory limitations on the Company;



•

The value of our mortgage servicing rights can be volatile;



•

Operational risks resulting from a high volume of financial transactions and increased reliance on technology;



•

Failure to obtain external financing on favorable terms, or at all, in the future could materially and adversely impact our growth strategy and prospects;



•

Our ability to originate loans could be restricted by regulations;



•

Changes in the state of the general economy and the financial markets could adversely affect our results of operations;



•

Our credit risk may increase in our commercial, construction and residential loan portfolios;



•

Interest rate shifts may reduce net interest income, our profits and asset values, and otherwise negatively impact our financial condition and results of operations;



•

If the allowance for loan losses is not sufficient to cover actual loan losses, earnings could decrease;



•

If the secondary market for our mortgage loans were to contract significantly, our earnings profile would be negatively affected and our ability to manage our balance sheet could be materially and adversely affected; and

•

The highly regulated environment of the financial services industry and the laws and regulations that govern our operations, corporate governance, executive compensation and accounting principles, or changes in any of them.

        The foregoing factors should not be construed as an exhaustive list and should be read in conjunction with other cautionary statements that are included in this Annual Report on Form 10-K as well as the items set forth under the heading "Risk Factors". If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise except as required by law. New risks and uncertainties arise from time to time, and it is not possible for us to predict those events or how they may affect us. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Overview

        We are a unitary thrift holding company headquartered in Southfield, Michigan with our primary branch operations in San Francisco and Los Angeles, California. Through our wholly owned bank subsidiary, Sterling Bank and Trust, F.S.B., a qualified thrift lender, we offer a broad range of loan products to the residential and commercial markets, as well as retail and business banking services.

        Since 2013, we have grown organically at a compound annual growth rate of 30% while maintaining stable margins and solid asset quality. We have made significant investments over the last several years in staffing and upgrading technology and system security. In 2017, we opened a loan production office near Seattle, Washington and a branch in New York City. During the first half of 2018, we plan to open two additional branches in Southern California and one branch in Seattle and a loan production office in New York City, with the intent to eventually convert such office to a branch. As of December 31, 2017, the Company had total consolidated assets of $2.96 billion, total consolidated deposits of $2.25 billion and total consolidated shareholders' equity of $273 million.

        Total assets increased $798 million, or 36.9%, to $2.96 billion at December 31, 2017 from $2.16 billion at December 31, 2016, primarily as a result of loan growth. We continue to focus on the residential mortgage market, construction, and commercial real estate lending. Net loans increased $612 million, or 30.9%, to $2.59 billion at December 31, 2017 from $1.98 billion at December 31, 2016.

        Our net income increased $4.7 million, or 14.3%, to $38.0 million for the year ended December 31, 2017, primarily as a result of income from loan growth outpacing corresponding increases in expenses.

Critical Accounting Policies and Estimates

        Our consolidated financial statements are prepared in accordance with U.S. GAAP and with general practices within the financial services industry. Application of these principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under current circumstances. These assumptions form the basis for our judgments about the carrying values of assets and liabilities that are not readily available from independent, objective sources. We evaluate our estimates on an ongoing basis. Use of alternative assumptions may have resulted in significantly different estimates. Actual results may differ from these estimates.

46

---

Table of Contents

        We have identified the following accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates, and the potential sensitivity of our financial statements to those judgments and assumptions, are critical to an understanding of our financial condition and results of operations. We believe that the judgments, estimates and assumptions used in the preparation of our financial statements are appropriate.

Allowance for Loan Losses

        The allowance for loan losses is a valuation allowance for probable incurred credit losses, increased or decreased by the provision for loan losses and decreased by charge offs less recoveries. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, should be charged off.

        The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers all other loans and is based on historical loss experience adjusted for general economic conditions and other qualitative factors by loan segment.

        Commercial lines of credit, construction loans, and commercial real estate loans are individually evaluated for impairment based upon a quarterly systematic review utilizing among other components our internal risk rating system, similar to those employed by banking regulators. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan's existing rate or at the fair value of collateral if repayment is expected solely from the collateral or operations of collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, are not separately identified for impairment disclosures.

        Loans which have been modified resulting in a concession, and with respect to which the borrower is experiencing financial difficulties, are considered troubled debt restructurings. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses on loans individually identified as impaired.

        The general reserve component covers all non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent three years. This actual loss experience is supplemented with economic and other factors based on the risks present for each portfolio segment. These economic and other risk factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; seasoning of loans where the borrower had limited credit history at origination; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations.

        The degree of risk in residential real estate lending depends primarily on the loan amount in relation to collateral value, the interest rate and the borrower's ability to repay in an orderly fashion.

Table of Contents

Economic trends determined by unemployment rates and other key economic indicators are closely correlated to the credit quality of these loans. Weak economic trends indicate that the borrowers' capacity to repay their obligations may be deteriorating. The classes identified by the Company in the residential real estate portfolio segment consist of residential first mortgages and residential second mortgages. Our residential first mortgages are further stratified by product and borrower characteristics.

        Adverse economic developments or an overbuilt market impact commercial real estate projects and may result in troubled loans. Trends in vacancy rates of commercial properties impact the credit quality of these loans. High vacancy rates reduce operating revenues and the ability for the properties to produce sufficient cash flow to service debt obligations. The classes identified by the Company in the commercial real estate portfolio segment consist of retail, multifamily, offices, hotels, industrial, gas stations, and other.

        The commercial lines of credit portfolio is comprised of loans to businesses such as sole proprietorships, partnerships, limited liability companies and corporations for the daily operating needs of the business. The risk characteristics of these loans vary based on the borrowers' business and industry as repayment is typically dependent on cash flows generated from the underlying business. These loans may be secured or unsecured. The classes identified by the Company in the commercial lines of credit portfolio segment consist of private banking loans and commercial & industrial ("C&I") lending.

        The construction loan portfolio is comprised of loans to builders and developers primarily for residential, commercial and mixed-use development. In addition to general commercial real estate risks, construction loans have additional risk of cost overruns, market deterioration during construction, lack of permanent financing and no operating history.

Securities

        Securities generally must be classified as held to maturity, available for sale or trading. Held-to-maturity securities are principally debt securities that we have both the positive intent and ability to hold to maturity. Other securities, such as required investments in Federal Home Loan Bank stock are carried at cost. Trading securities are held primarily for sale in the near term to generate income. Securities that do not meet the definition of trading or held to maturity are classified as available for sale.

        The classification of investment securities is significant since it directly impacts the accounting for unrealized gains and losses on these securities. Unrealized gains and losses on trading securities flow directly through earnings during the periods in which they arise. Trading and available-for-sale securities are measured at fair value each reporting period. Unrealized gains and losses on available-for-sale securities are recorded as a separate component of shareholders' equity (accumulated other comprehensive income or loss) and do not affect earnings until realized or deemed to be other-than-temporary impairment, or OTTI. Investment securities that are classified as held to maturity are recorded at amortized cost, unless deemed to be OTTI.

        The fair value of securities is a critical accounting estimate. Changes in the fair value estimates that are likely to occur from period to period, or the use of different estimates that we could have reasonably used in the current period, could have a material impact on our financial position, results of operations or liquidity.

        Delinquent Loans.    The following tables set forth our loan delinquencies, including nonaccrual loans, by type and amount at the dates indicated.

 

Nonperforming Assets.

        Nonperforming assets include loans that are 90 or more days past due or on nonaccrual status, including troubled debt restructurings and real estate and other loan collateral acquired through foreclosure and repossession. Troubled debt restructurings include loans for economic or legal reasons related to the borrower's financial difficulties, for which we grant a concession to the borrower that we would not consider otherwise. At December 31, 2017 and 2016, we had one troubled debt restructuring in nonaccrual with a balance of $79,000 and $99,000, respectively. Loans 90 days or greater past due may remain on an accrual basis if adequately collateralized and in the process of collection. At December 31, 2017 and 2016, we had $131,000 and $155,000, respectively, of accruing loans past due 90 days, which consisted primarily of government guaranteed loans. For nonaccrual loans, interest previously accrued but not collected is reversed and charged against income at the time a loan is placed on nonaccrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

        Real estate that we acquire as a result of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned until it is sold. When property is acquired, it is initially recorded at the fair value less costs to sell at the date of foreclosure, establishing a new cost basis. Holding costs and declines in fair value after acquisition of the property result in charges against income.

Allowance for Loan Losses.

        Please see "—Critical Accounting Policies and Estimates—Allowance for Loan Losses" for additional discussion of our allowance policy.

        The allowance for loan losses is maintained at levels considered adequate by management to provide for probable loan losses inherent in the loan portfolio as of the consolidated balance sheet reporting dates. The allowance for loan losses is based on management's assessment of various factors affecting the loan portfolio, including portfolio composition, delinquent and nonaccrual loans, national and local business conditions and loss experience and an overall evaluation of the quality of the underlying collateral.

Table of Contents

        The following table sets forth activity in our allowance for loan losses for the periods indicated.

        Allocation of Allowance for Loan Losses.    The following tables set forth the allowance for loan losses allocated by loan category. The allowance for loan losses allocated to each category is not

53

---

Table of Contents

necessarily indicative of future losses in any particular category and does not restrict the use of the allowance to absorb losses in other categories.

 

        The allowance for loan losses as a percentage of loans was 0.71%, 0.74% and 0.69% as of December 31, 2017, 2016 and 2015, respectively. The decrease in the allowance percentage from December 31, 2016 to December 31, 2017 was primarily due to change in risk profile associated with the seasoning of loans originated in the greater Los Angeles market. Increases in both commercial real estate and construction allowance for loan losses in 2017 were warranted due to overall portfolio growth, property type concentrations, and trends in the risk rating of loans in these segments.

        The allowance for loan losses consists of general and allocated components. The general component relates to pools of non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The allocated component relates to loans that are classified as impaired, whereby an allowance is established when the discounted cash flows, collateral value or observable market price of the impaired loan is lower than the carrying value of that loan.

        A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by us in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment

54

---

Table of Contents

shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The measurement of an impaired loan is based on (i) the present value of expected future cash flows discounted at the loan's effective interest rate, (ii) the loan's observable market price or (iii) the fair value of the collateral if the loan is collateral dependent.

        At December 31, 2017, 2016 and 2015, we had impaired loans of $3.3 million, $3.4 million and $7.5 million, respectively.

        Commercial real estate and construction loans, and commercial lines of credit are individually evaluated for impairment. Larger groups of smaller balance homogeneous loans, such as residential real estate and consumer, are collectively evaluated for impairment.

        Troubled debt restructurings are included in the impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, we determine the amount of reserve in accordance with the accounting policy for the allowance for loan losses.

        Interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. A loan is moved to nonaccrual status in accordance with our loan policy, typically after 90 days of non-payment.

        All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

        Although we believe that we use the best information available to establish the allowance for loan losses, future adjustments to the allowance for loan losses may be necessary and our results of operations could be adversely affected if circumstances differ substantially from the assumptions used in making the determinations. Furthermore, while we believe we have established our allowance for loan losses in conformity with generally accepted accounting principles in the United States of America, there can be no assurance that regulators, in reviewing our loan portfolio, will not require us to increase our allowance for loan losses. In addition, because future events affecting borrowers and collateral cannot be predicted with certainty, there can be no assurance that the existing allowance for loan losses is adequate or that increases will not be necessary should the quality of any loans deteriorate as a result of the factors discussed above. Any material increase in the allowance for loan losses may adversely affect our financial condition and results of operations.

Investment Securities Portfolio

        The following table sets forth the amortized cost and estimated fair value of our available-for-sale investment securities portfolio at the dates indicated. Our investment securities portfolio has increased in recent years in conjunction with overall asset growth.

        At December 31, 2017 and 2016, we had no investments in a single company or entity, other than government and government agency securities, with an aggregate book value in excess of 10% of our shareholders' equity.

        We review the investment securities portfolio on a quarterly basis to determine the cause, magnitude and duration of declines in the fair value of each security. In estimating other-than-temporary impairment (OTTI), we consider many factors including: (1) the length of time and extent that fair value has been less than cost, (2) the financial condition and near term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether we have the intent to sell the security or more likely than not will be required to sell the security before its anticipated recovery. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. The assessment of whether any other than temporary decline exists may involve a high degree of subjectivity and judgment and is based on the information available to management at a point in time. We evaluate securities for OTTI at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation.

        At December 31, 2017 and 2016, securities in unrealized loss positions included U.S. Treasury securities, a Trust Preferred CDO, and a mutual fund. Because (i) the decline in fair value is attributable to changes in interest rates and illiquidity, not credit quality, (ii) we do not have the intent to sell the investment securities and (iii) it is likely that we will not be required to sell the investment securities before their anticipated recovery, we do not consider the securities to be other-than-temporarily impaired at December 31, 2017 and 2016.

        No investment securities related impairment charges were recorded for the years ended December 31, 2017, 2016 and 2015.
