Common Stock

This is the initial public offering of shares of common stock of Luther Burbank Corporation, the bank holding company for Luther Burbank Savings, our principal subsidiary and a California chartered bank.

We are offering 11,350,000 shares of our common stock. Prior to this offering, there has been no public market for our common stock. We currently expect the initial public offering price per share of our common stock to be between $10.50 and $12.50. We have appliedreceived approval to list the common stock on the NASDAQ Global Select Market under the symbol "LBC."

In connection with the termination of our status as an S Corporation, we intend to use a portion of the net proceeds to us from the offering to fund a cash distribution to our existing shareholders, immediately after the closing of this offering, in the amount of $40.0 million. The distribution is intended to be non-taxable to our existing shareholders and represents a substantial portion of our S Corporation earnings that have been, or will be, taxed to our existing shareholders, but not previously distributed to them. See "Use of Proceeds."

S CORPORATION STATUS

Since 2002, we have elected to be taxed for U.S. federal income tax purposes as an "S Corporation" under the provisions of Sections 1361 through 1379 of the Internal Revenue Code of 1986, as amended (the "Code").

INDUSTRY AND MARKET DATA

This prospectus includes statistical and other industry and market data that we obtained from government reports and other third party sources. Our internal data, estimates and forecasts are based on information obtained from government reports, trade and business organizations and other contacts in the markets in which we operate and our management's understanding of industry conditions. Although we believe that this information (including the industry publications and third party research, surveys and studies) is accurate and reliable, we have not independently verified such information. In addition, estimates, forecasts and assumptions are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the "Risk Factors" section and elsewhere in this prospectus. Finally, forward-looking information obtained from these sources is subject to the same qualifications and the additional uncertainties regarding the other forward-looking statements in this prospectus.

IMPLICATIONS OF BEING AN EMERGING GROWTH COMPANY

As a company with less than $1.07 billion in revenue during our last fiscal year, we qualify as an "emerging growth company" under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting requirements and is relieved of other significant requirements that are otherwise generally applicable to other public companies. Among other factors, as an emerging growth company:

•

we may present only two years of audited financial statements, discuss only our results of operations for two years in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and provide less than five years of selected financial data in this registration statement;

•

we are exempt from the requirement to provide an opinion from our auditors on the design and operating effectiveness of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;

•

we may choose not to comply with any new requirements adopted by the Public Company Accounting Oversight Board, or PCAOB, requiring mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and our audited financial statements;

•

we are permitted to provide less extensive disclosure regarding our executive compensation arrangements pursuant to the rules applicable to smaller reporting companies, which means we do not have to include a compensation discussion and analysis and other disclosure regarding our executive compensation in this prospectus; and

•

we are not required to hold nonbinding advisory votes on executive compensation or golden parachute arrangements.

We may take advantage of these provisions for up to five years unless we earlier cease to qualify as an emerging growth company. We will cease to qualify as an emerging growth company if we have more than $1.07 billion in annual gross revenues, as that amount may be periodically adjusted by the Securities and Exchange Commission, or SEC, we become a "large accelerated filer," including having more than $700.0 million in market value of our common stock held by non-affiliates, or we issue more than $1.0 billion of non-convertible debt in a three-year period. We have elected to adopt the reduced disclosure requirements described above regarding the number of periods for which we are providing audited financial statements and selected financial data, and our executive compensation arrangements for purposes of the registration statement of which this prospectus is a part. In addition, we expect to take advantage of the reduced reporting and other requirements of the JOBS Act with respect to the periodic reports we will file with the SEC and proxy statements that we use to solicit proxies from our shareholders.

Table of Contents

Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

The JOBS Act exempts emerging growth companies from compliance with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act of 1933, or Securities Act, registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, or Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of this extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make our financial statements not comparable with those of a public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period because of the potential differences in accounting standards used. We cannot predict if investors will find our common stock less attractive as a result of our election to rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

RISK FACTORS

An investment in our common stock involves a significant degree of risk. The material risks and uncertainties that management believes affect us are described below. Before you decide to invest in our common stock, you should carefully read and consider the risk factors described below as well as the other information included in this prospectus. Any of these risks, if they are realized, could materially adversely affect our business, financial condition, and results of operations, and consequently, the value of our common stock. Additional risks and uncertainties not currently known to us or that we currently believe to be immaterial may also materially and adversely affect us. This prospectus also contains forward-looking statements that involve risks and uncertainties. If any of the matters included in the following information about risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially and adversely affected. In any such case, you could lose all or a portion of your original investment.

Risks Related to Our Business

Our business and operations may be materially adversely affected by weak economic conditions.

Our business and operations, which primarily consist of banking activities, including lending money to customers in the form of real estate secured loans and borrowing money from customers in the form of deposits, are sensitive to general business and economic conditions in the U.S. generally, and on the West Coast in particular. The economic conditions in our local markets may be different from the economic conditions in the U.S. as a whole. If economic conditions in the U.S. or any of our markets weaken, our growth and profitability from our operations could be constrained. In addition, foreign economic and political conditions could affect the stability of global financial markets, which could hinder economic growth. The current economic environment is characterized by interest rates near historically low levels, which impact our ability to attract deposits and to generate attractive earnings through our loan and investment portfolios. All these factors can individually or in the aggregate be detrimental to our business, and the interplay between these factors can be complex and unpredictable. Unfavorable market conditions can result in a deterioration in the credit quality of our borrowers and the demand for our products and services, an increase in the number of delinquencies, defaults and charge-offs, additional provisions for loan losses, a decline in the value of our collateral, and an overall material adverse effect on the quality of our loan portfolio.

Our business is also significantly affected by monetary and related policies of the U.S. federal government and its agencies. Uncertainty about the federal fiscal policymaking process, the medium and long-term fiscal outlook of the federal government, and future tax rates are concerns for businesses, consumers and investors in the U.S. 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 conditions and results of operations.

We are subject to interest rate risk, which could adversely affect our profitability.

Our profitability, like that of most financial institutions, depends to a large extent on our net interest income, which is the difference between our interest income on interest-earning assets, such as loans and investment securities, and our interest expense on interest-bearing liabilities, such as deposits and borrowings.

Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Board of

Table of Contents

Governors of the Federal Reserve System, or the Federal Reserve. Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and securities and the interest we pay on deposits and borrowings, but such changes could affect our ability to originate loans and obtain deposits, the fair value of our financial assets and liabilities, and the average duration of our assets. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings. Any substantial, unexpected or prolonged change in market interest rates could have a material adverse impact on our business, financial condition and results of operations.

Our interest sensitivity profile was liability sensitive as of September 30, 2017. When short-term interest rates rise, the rate of interest we pay on our interest-bearing liabilities, such as deposits, may rise more quickly than the rate of interest that we receive on our interest-earning assets, such as loans, which may cause our net interest income to decrease. Additionally, a shrinking yield premium between short-term and long-term market interest rates, a pattern typically indicative of investors' waning expectations of future growth and inflation, commonly referred to as a flattening of the yield curve, typically reduces our profit margin as we borrow at shorter terms than the terms at which we lend and invest.

In addition, an increase in interest rates could also have a negative impact on our results of operations by reducing the ability of borrowers to repay their current loan obligations. These circumstances could not only result in increased loan defaults, foreclosures and charge-offs, but also reduce collateral values and necessitate further increases to the allowance for loan losses, which could have a material adverse effect on our business, financial condition and results of operations.

We are subject to credit risk, which could adversely affect our profitability.

Our business depends on our ability to successfully measure and manage credit risk. As a lender, we are exposed to the risk that the principal of, or interest on, a loan will not be paid timely or at all or that the value of any collateral supporting a loan will be insufficient to cover our outstanding exposure. In addition, we are exposed to risks with respect to the period of time over which the loan may be repaid, risks relating to loan underwriting, risks resulting from changes in economic and industry conditions, and risks inherent in dealing with individual loans and borrowers. The creditworthiness of a borrower is affected by many factors including local market conditions and general economic conditions. If the overall economic climate in the U.S., generally, or in our market areas specifically, experiences material disruption, our borrowers may experience difficulties in repaying their loans, the collateral we hold may decrease in value or become illiquid, and the level of nonperforming loans, charge-offs and delinquencies could rise and require significant additional provisions for loan losses. Additional factors related to the credit quality of multifamily residential and other commercial real estate loans include the quality of management of the business and tenant vacancy rates.

Our risk management practices, such as monitoring the concentration of our loans within specific markets and our credit approval, review and administrative practices, may not adequately reduce credit risk, and our credit administration personnel, policies and procedures may not adequately adapt to changes in economic or any other conditions affecting customers and the quality of the loan portfolio. Many of our loans are made to small businesses that are less able to withstand competitive, economic and financial pressures than larger borrowers. Consequently, we may have significant exposure if any of these borrowers becomes unable to pay their loan obligations as a result of economic or market conditions, or personal circumstances, such as divorce, unemployment or death. A failure to effectively measure and limit the credit risk associated with our loan portfolio may result in loan defaults, foreclosures and additional charge-offs, and may necessitate that we significantly increase our allowance for loan losses, each of which

Table of Contents

could adversely affect our net income. As a result, our inability to successfully manage credit risk could have a material adverse effect on our business, financial condition and results of operations.

Our multifamily residential and commercial real estate loan portfolios generally carry greater credit risk than loans secured by our other mortgage loans.

Our loan portfolio consists primarily of multifamily residential and, to a lesser extent, other commercial real estate loans, which are secured by industrial, office and retail properties. As of September 30, 2017, our multifamily residential loans totaled $2.6 billion, or 56.8% of our loan portfolio, and our other commercial real estate loans totaled $95.7 million, or 2.1% of our loan portfolio. Nonperforming multifamily residential loans were $2.3 million and nonperforming other commercial real estate loans were $682 thousand at September 30, 2017. Multifamily residential and commercial real estate loans may carry more risk as compared to single family residential lending, because they typically involve larger loan balances concentrated with a single borrower or groups of related borrowers. In addition, these loans expose a lender to greater credit risk than those secured by residential real estate. The payment on these loans that are secured by income producing properties are typically dependent on the successful operation of the related real estate property and may subject us to risks from adverse conditions in the real estate market or the general economy. Investment in these properties by our customers is influenced by prices and return on investment, as well as changes to applicable laws regarding, among other things, rent control, personal and corporate tax reform, pass-through rules, immigration and fiscal and economic policy. The collateral securing these loans typically cannot be liquidated as easily as single family residential real estate, which may lead to longer holding periods as compared to single family residential properties.

If these properties become less attractive investments, demand for our loans would decrease. In addition, unexpected deterioration in the credit quality of our multifamily residential or commercial real estate loan portfolios could require us to increase our provision for loan losses, which would reduce our profitability and could materially adversely affect our business, financial condition and results of operations.

Our business and operations are concentrated in California and Washington, and we are more sensitive than our more geographically diversified competitors to adverse changes in the local economy.

Unlike many of our larger competitors that maintain significant operations located outside our market areas, substantially all of our customers are individuals and businesses located and doing business in the state of California. As of September 30, 2017, approximately 88% of the loans in our portfolio measured by dollar amount were secured by collateral located in California and 12% of the loans in our portfolio measured by dollar amount were secured by collateral located in Washington. In addition, 50.0% of our real estate loans measured by dollar amount, were secured by collateral located in Los Angeles County and Orange County. Therefore, our success will depend upon the general economic conditions in these areas, which we cannot predict with certainty. As a result, our operations and profitability may be more adversely affected by a local economic downturn than those of large, more geographically diverse competitors. A downturn in the local economy could make it more difficult for our borrowers to repay their loans and may lead to loan losses that are not offset by operations in other markets; it may also reduce the ability of depositors to make or maintain deposits with us. For these reasons, any regional or local economic downturn could have a material adverse effect on our business, financial condition and results of operations.

Our ability to conduct our business could be disrupted by natural or man-made disasters.

A significant number of our offices, and a significant portion of the real estate securing loans we make, and our borrowers' business operations in general, are located in California. California has had and will continue to have major earthquakes in areas where a significant portion of the collateral and assets of our

Table of Contents

borrowers are concentrated. California is also prone to fires, mudslides, floods and other natural disasters, such as the recent fires that impacted Napa, Sonoma and surrounding counties, including Santa Rosa, the location of our corporate headquarters and our main banking office. Additionally, acts of terrorism, war, civil unrest, violence, or other man-made disasters could also cause disruptions to our business or to the economy as a whole. The occurrence of natural or man-made disasters could destroy, or cause a decline in the value of, mortgaged properties or other assets that serve as our collateral and increase the risk of delinquencies, defaults, foreclosures and losses on our loans, damage our banking facilities and offices, negatively impact regional economic conditions, result in a decline in loan demand and loan originations, result in drawdowns of deposits by customers impacted by disasters and negatively impact the implementation of our growth strategy. We have implemented a disaster recovery and business continuity plan that allows us to move critical functions to a backup data center in the event of a catastrophe. Although this program has been tested, we cannot guarantee its effectiveness in any disaster scenarios. Regardless of the effectiveness of our disaster recovery and business continuity plan, the occurrence of any natural or man-made disaster could have a material adverse effect on our business, financial condition and results of operations.

We operate in a highly competitive market and face increasing competition from a variety of traditional and new financial services providers, which could adversely impact our profitability.

We have many competitors. Our principal competitors are commercial and community banks, credit unions, savings and loan associations, mortgage banking firms and online mortgage lenders, including large national financial institutions that operate in our market area. Many of these competitors are larger than us, have significantly more resources and greater brand recognition than we do, and may be able to attract customers more effectively than we can. We compete with these other financial institutions both in attracting deposits and making loans. We expect competition to continue to increase as a result of legislative, regulatory and technological changes and the continuing trend of consolidation in the financial services industry. Our profitability depends upon our continued ability to successfully compete with traditional and new financial services providers, some of which maintain a physical presence in our market areas and others of which maintain only a virtual presence. Increased competition could require us to increase the rates we pay on deposits or lower the rates that we offer on loans, which could reduce our profitability. Our failure to compete effectively in our market could restrain our growth or cause us to lose market share, which could have a material adverse effect on our business, financial condition and results of operations.

We may not be able to retain or grow our core deposit base, which could adversely impact our funding costs.

Like many financial institutions, we rely on customer deposits as our primary source of funding for our lending activities, and we continue to seek customer deposits to maintain this funding base. Our future growth will largely depend on our ability to retain and grow our deposit base. As of September 30, 2017, we had $3.9 billion in deposits and a loan to deposit ratio of 120.9%, which is higher than the level maintained by many other banks. As of the same date, using deposit account related information such as tax identification numbers, account vesting and account size, we estimated that $830 million of our deposits exceeded the insurance limits established by the Federal Deposit Insurance Corporation, or FDIC. None of our deposits are governmental deposits secured by collateral. Although we have historically maintained a high deposit customer retention rate, these deposits are subject to potentially dramatic fluctuations in availability or price due to certain factors outside of our control, such as increasing competitive pressures for deposits, changes in interest rates and returns on other investment classes, customer perceptions of our financial health and general reputation, or a loss of confidence by customers in us or the banking sector generally, which could result in significant outflows of deposits within short periods of time or significant changes in pricing necessary to maintain current customer deposits or attract

Table of Contents

additional deposits. Additionally, any such loss of funds could result in lower loan originations, which could have a material adverse effect on our business, financial condition and results of operations.

Proposed changes in tax laws could have an adverse affect on us, our industry, our customers, the value of collateral securing our loans and demand for our loans.

Changes in tax laws contained in proposed legislation under discussion contain a number of provisions which could have an impact on the banking industry, borrowers and the market for single family residential and multifamily residential real estate. Among the proposed changes are: lower limits on the deductibility of mortgage interest on single family residential mortgages; the elimination of deductibility of mortgage interest for second homes; limitations on deductibility of business interest expense; limitations on the deductibility of property taxes; and the elimination of the deductibility of state and local income taxes. We cannot predict whether any specific legislation will be enacted or the terms of any such legislation. However, if such proposals were to be enacted, such changes may have an adverse affect on the market for and valuation of single family residential properties and multifamily residential properties, and on the demand for such loans in the future. If home ownership or multifamily residential property ownership become less attractive, demand for our loans would decrease. The value of the properties securing loans in our portfolio may be adversely impacted as a result of the changing economics of home ownership and multifamily residential ownership, which could require an increase in our provision for loan losses, which would reduce our profitability and could materially adversely affect our business, financial condition and results of operations. Additionally, certain borrowers could become less able to service their debts if these changes become effective. These changes could adversely affect our business, financial condition and results of operations.

Our reputation is critical to our business, and damage to it could have a material adverse effect on us.

A key differentiating factor for our business is the strong reputation we are building in our markets. Maintaining a positive reputation is critical to attracting and retaining customers and employees. Adverse perceptions of us could make it more difficult for us to execute on our strategy. Harm to our reputation can arise from many sources, including actual or perceived employee misconduct, errors or misconduct by our third party vendors or other counterparties, litigation or regulatory actions, our failure to meet our high customer service and quality standards and compliance failures. Negative publicity about us, whether or not accurate, may damage our reputation, which could have a material adverse effect on our business, financial condition and results of operations.

Our allowance for loan losses may be inadequate to absorb losses inherent in the loan portfolio, which could have a material adverse effect on our business, financial condition and results of operations.

Experience in the banking industry indicates that a portion of our loans will become delinquent, and that some may only be partially repaid or may never be repaid at all. We may experience losses for reasons beyond our control, such as the impact of general economic conditions on customers and their businesses. In determining the size of our allowance for loan losses, we rely on an analysis of our loan portfolio considering historical loss experience, volume and types of loans, trends in classification, volume and trends in delinquencies and non-accruals, economic conditions and other pertinent information. The determination of the appropriate level of the allowance for loan losses is inherently highly subjective and requires us to make significant estimates of and assumptions regarding current credit risk and future trends, all of which may change materially. Although we endeavor to maintain our allowance for loan losses at a level adequate to absorb any inherent losses in the loan portfolio, these estimates of loan losses are necessarily subjective and their accuracy depends on the outcome of future events. As of September 30, 2017, the allowance for loan losses was $29.0 million. Non-accruing loans totaled $5.8 million and loans 30-89 days past due were $5.0 million as of September 30, 2017.

Table of Contents

Over the last three years, we have enjoyed a relatively low level of nonperforming assets and net charge-offs, both in absolute dollars, and as a percentage of loans. As a result of this historical performance, we have experienced periodic recaptures of our prior provisions for loan losses (income), which positively impacted our earnings in 2015, 2016 and 2017. However, should a higher portion of our loans become delinquent, or if some of our loans are only partially repaid, we may experience losses for reasons beyond our control. Despite our underwriting criteria and historical experience, we may be particularly susceptible to losses due to: (i) the geographic concentration of our loans; (ii) the concentration of higher risk loans, such as commercial real estate loans; and (iii) the relative lack of seasoning of some of our loans. As a result, we may not be able to maintain our relatively low levels of nonperforming assets and charge-offs.

Deterioration of economic conditions affecting borrowers, new information regarding existing loans, inaccurate management assumptions, identification of additional problem loans and other factors, both within and outside of our control, may result in our experiencing higher levels of nonperforming assets and charge-offs, and incurring loan losses in excess of our current allowance for loan losses, requiring us to make material additions to our allowance for loan losses, which could have a material adverse effect on our business, financial condition and results of operations.

Additionally, federal and state banking regulators, as an integral part of their supervisory function, periodically review the allowance for loan losses. These regulatory agencies may require us to increase our provision for loan losses or to recognize further loan charge-offs based upon their judgments, which may be different from ours. If we need to make significant and unanticipated increases in the loss allowance in the future, or to take additional charge-offs for which we have not established adequate reserves, our results of operations and financial condition could be materially adversely affected at that time.

We are dependent on our management team and key employees, and if we are not able to retain them, our business operations could be materially adversely affected.

Our success depends, in large part, on our management team and key employees. Our management team has significant industry experience, although a number of members of our senior management team have only been with us for a few years. In addition, our loan origination activities are conducted by a small number of individuals.

Our future success also depends on our continuing ability to attract, develop, motivate and retain key employees. Qualified individuals are in high demand, and we may incur significant costs to attract and retain them. Because the market for qualified individuals is highly competitive, we may not be able to attract and retain qualified officers or candidates. The loss of any of our management team or our key employees could materially adversely affect our ability to execute our business strategy, and we may not be able to find adequate replacements on a timely basis, or at all. We cannot ensure that we will be able to retain the services of any members of our management team or other key employees. Though we have employment agreements in place with certain members of our management team they may still elect to leave at any time. Failure to attract and retain a qualified management team and qualified key employees could have a material adverse effect on our business, financial condition and results of operations.

We may not be able to maintain consistent growth, earnings or profitability.

There can be no assurance that we will be able to continue to grow and to remain profitable in future periods, or, if profitable, that our overall earnings will remain consistent with our prior results of operations, or increase in the future. Our growth in recent years has been driven primarily by a strong multifamily housing market in our geographic footprint. A downturn in economic conditions in our markets, particularly in the real estate market, heightened competition from other financial services providers, an

Table of Contents

inability to retain or grow our core deposit base, regulatory and legislative considerations, and failure to attract and retain high-performing talent, among other factors, could limit our ability to grow assets, or increase profitability, as rapidly as we have in the past. Sustainable growth requires that we manage our risks by following prudent loan underwriting standards, balancing loan and deposit growth without materially increasing interest rate risk or compressing our net interest margin, maintaining more than adequate capital at all times, hiring and retaining qualified employees and successfully implementing our strategic initiatives. We have also recently entered, or expect to enter, new markets, including Portland, Oregon. We may not have, or may not be able to develop, the knowledge or relationships necessary to be successful in these new markets. Our failure to sustain our historical rate of growth, adequately manage the factors that have contributed to our growth or successfully enter new markets could have a material adverse effect on our earnings and profitability and, therefore on our business, financial condition and results of operations.

We may not be able to manage our growth effectively, which could adversely affect our business.

We may face a variety of risks and difficulties in pursuing our organic growth strategy and maintaining our growth, including:

•

maintaining asset quality;

•

finding suitable markets for expansion;

•

attracting funding to support additional growth;

•

managing execution risks;

•

attracting and retaining qualified management personnel and bankers;

•

maintaining adequate capital;

•

managing a growing number of customer relationships;

•

scaling technology platforms;

•

exceeding $10.0 billion or more in assets, which will subject us to additional regulatory burdens and expenses; and

•

achieving expected additional performance and production from our bankers.

To manage our growth and maintain adequate information and reporting systems within our organization, we must identify, hire and retain qualified employees, particularly in the accounting and operational areas of our business. We must also successfully implement improvements to, or integrate, our management information and control systems, procedures and processes in an efficient and timely manner and identify deficiencies in existing systems and controls. In particular, our controls and procedures must be able to accommodate an increase in loan volume in various markets and the infrastructure that comes with expanding operations, including new branches. Our growth strategy may divert management from our existing franchises and may require us to incur additional expenditures to expand our administrative and operational infrastructure. If we are unable to effectively manage and grow our banking franchise, we may experience compliance and operational problems, have to slow the pace of growth, or have to incur additional expenditures beyond current projections to support such growth, any one of which could materially and adversely affect our business, financial condition and results of operations.

Regulatory requirements affecting our loans secured by commercial real estate could limit our ability to leverage our capital and adversely affect our growth and profitability.

The federal banking agencies have issued guidance for institutions that are deemed to have concentrations in commercial real estate lending. Pursuant to the supervisory criteria contained in the guidance for identifying institutions with a potential commercial real estate concentration risk, institutions which have (i) total reported loans for construction, land development, and other land which represent 100% or more of an institution's total risk-based capital; or (ii) total commercial real estate loans representing 300% or

Table of Contents

more of the institution's total risk-based capital and the outstanding balance of the institution's commercial real estate loan portfolio has increased 50% or more during the prior 36 months are identified as having potential commercial real estate concentration risk. Institutions which are deemed to have concentrations in commercial real estate lending are expected to employ heightened levels of risk management with respect to their commercial real estate portfolios, and may be required to hold higher levels of capital. We have a concentration in commercial real estate loans, and multifamily residential real estate loans in particular, and we have experienced significant growth in our commercial real estate portfolio in recent years. From December 31, 2014 through December 31, 2016, our commercial real estate loan balances have increased by $454.2 million. As of September 30, 2017, commercial real estate loans represent 525% of the Company's total risk-based capital, of which multifamily residential real estate loans, the vast majority of which are 50% risk weighted for regulatory capital purposes, were 498% of the Company's total risk-based capital. Management has extensive experience in commercial real estate lending, and has implemented and continues to maintain heightened portfolio monitoring and reporting, and strong underwriting criteria with respect to its commercial real estate portfolio. Nevertheless, we could be required to maintain higher levels of capital as a result of our commercial real estate concentration, which could limit our growth, require us to obtain additional capital, and have a material adverse effect on our business, financial condition and results of operations.

Lack of seasoning of our loan portfolio could increase risk of credit defaults in the future.

As a result of our organic growth over the past several years, as of September 30, 2017, approximately $3.9 billion, or 85%, of the loans in our loan portfolio were first originated since January 1, 2014. In general, loans do not begin to show signs of credit deterioration or default until they have been outstanding for some period of time, a process referred to as "seasoning." As a result, a portfolio of older loans will usually behave more predictably than a newer portfolio. Although a significant portion of our multifamily portfolio are refinancings of prior loans on the same property, a large portion of our loan portfolio is relatively new, and therefore the current level of delinquencies and defaults may not represent the level that may prevail as the portfolio becomes more seasoned and may not serve as a reliable basis for predicting the health and nature of our loan portfolio, including net charge-offs and the ratio of nonperforming assets in the future. Our limited experience with these loans does not provide us with a significant history pattern with which to judge future collectability or performance. However, we believe that our stringent credit underwriting process, our ongoing credit review processes, and our history of successful management of our loan portfolio, mitigate these risks. Nevertheless, if delinquencies and defaults increase, we may be required to increase our provision for loan losses, which could have a material adverse effect on our business, financial condition and results of operations.

Liquidity risk could impair our ability to fund operations and meet our obligations as they become due and failure to maintain sufficient liquidity could materially adversely affect our growth, business, profitability and financial condition.

Liquidity is essential to our business. Liquidity risk is the potential that we will be unable to meet our obligations as they become due because of an inability to liquidate assets or obtain adequate funding at a reasonable cost, in a timely manner and without adverse conditions or consequences. We require sufficient liquidity to fund asset growth, meet customer loan requests, customer deposit maturities and withdrawals, payments on our debt obligations as they come due and other cash commitments under both normal operating conditions and other unpredictable circumstances, including events causing industry or general financial market stress. Liquidity risk can increase due to a number of factors, including an over-reliance on a particular source of funding or market-wide phenomena such as market dislocation and major disasters. Factors that could detrimentally impact access to liquidity sources include, but are not limited to, a decrease in the level of our business activity as a result of a downturn in the markets in which our loans are concentrated, adverse regulatory actions against us, or changes in the liquidity needs of our depositors.

Table of Contents

Market conditions or other events could also negatively affect the level or cost of funding, affecting our ongoing ability to accommodate liability maturities and deposit withdrawals, meet contractual obligations, and fund asset growth and new business transactions at a reasonable cost, in a timely manner, and without adverse consequences. Our inability to raise funds through deposits, borrowings, the sale of loans, and other sources could have a substantial negative effect on our business, and could result in the closure of the Bank. Our access to funding sources in amounts adequate to finance our activities or on acceptable terms could be impaired by factors that affect our organization specifically or the financial services industry or economy in general. Any substantial, unexpected, and/or prolonged change in the level or cost of liquidity could impair our ability to fund operations and meet our obligations as they become due and could have a material adverse effect on our business, financial condition and results of operations.

We rely on customer deposits, advances from the Federal Home Loan Bank of San Francisco, or FHLB, and brokered deposits to fund our operations. Although we have historically been able to replace maturing deposits and advances if desired, including throughout the recent recession, we may not be able to replace such funds in the future if our financial condition, the financial condition of the FHLB or market conditions change. FHLB borrowings and other current sources of liquidity may not be available or, if available, sufficient to provide adequate funding for operations.

Limits on our ability to use brokered deposits as part of our funding strategy may adversely affect our ability to grow.

A "brokered deposit" is any deposit that is obtained from or through the mediation or assistance of a deposit broker. These deposit brokers attract deposits from individuals and companies throughout the country and internationally whose deposit decisions are based almost exclusively on obtaining the highest interest rates. We have used brokered deposits in the past, and we intend to continue to use brokered deposits as one of our funding sources to support future growth. As of September 30, 2017, brokered deposits represented approximately 9.4% of our total deposits and equaled $363 million. Currently, our brokered deposits have a comparable cost to our non-brokered, consumer and business deposits. There are risks associated with using brokered deposits. In order to continue to maintain our level of brokered deposits, we may be forced to pay higher interest rates than those contemplated by our asset-liability pricing strategy. In addition, banks that become less than "well-capitalized" under applicable regulatory capital requirements may be restricted in their ability to accept or renew, or prohibited from accepting or renewing, brokered deposits. If this funding source becomes more difficult to access, we will have to seek alternative funding sources in order to continue to fund our growth. This may include increasing our reliance on FHLB borrowing, attempting to attract additional non-brokered deposits, and selling loans. There can be no assurance that brokered deposits will be available, or if available, sufficient to support our continued growth. The unavailability of a sufficient volume of brokered deposits could have a material adverse effect on our business, financial condition and results of operations.

New lines of business, products, product enhancements or services may subject us to additional risk.

From time to time, we may implement new lines of business or offer new products and product enhancements as well as new services within our existing lines of business. We recently expanded our offerings of business and consumer deposit accounts and cash management services for businesses. There are substantial risks and uncertainties associated with these efforts. In developing, implementing or marketing new lines of business, products, product enhancements or services, we may invest significant time and resources. We may underestimate the appropriate level of resources or expertise necessary to make new lines of business or products successful or to realize their expected benefits. We may not achieve the milestones set in initial timetables for the development and introduction of new lines of business, products, product enhancements or services, and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives and shifting market

Table of Contents

preferences, may also impact the ultimate implementation of a new line of business or offerings of new products, product enhancements or services. Any new line of business, product, product enhancement or service could have a significant impact on the effectiveness of our system of internal controls. We may also decide to discontinue businesses or products, due to lack of customer acceptance or unprofitability. Failure to successfully manage these risks in the development and implementation of new lines of business or offerings of new products, product enhancements or services 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 by or on behalf of customers and counterparties, including financial information. We may also 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 customers' representations that their financial statements conform to GAAP and present fairly, in all material respects, the financial condition, results of operations and cash flows of the customer. 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 customers. Our financial condition, results of operations, financial reporting and reputation could be negatively affected if we rely on materially misleading, false, inaccurate or fraudulent information.

We depend on information technology and telecommunications systems of third parties, and any systems failures or interruptions could adversely affect our operations and financial condition.

Our business depends on the successful and uninterrupted functioning of our information technology and telecommunications systems. We outsource many of our major systems, such as data processing, deposit processing, loan origination, email and anti-money laundering monitoring systems. Of particular significance is our long term contract for core data processing services with Fiserv. The failure of these systems, or the termination of a third party software license or service agreement on which any of these systems is based, could interrupt our operations, and we could experience difficulty in implementing replacement solutions. In many cases our operations rely heavily on secured processing, storage and transmission of information and the monitoring of a large number of transactions on a minute-by-minute basis, and even a short interruption in service could have significant consequences. Because our information technology and telecommunications systems interface with and depend on third party systems, we could experience service denials if demand for such services exceeds capacity or such third party systems fail or experience interruptions. If significant, sustained or repeated, a system failure or service denial could compromise our ability to operate effectively, damage our reputation, result in a loss of customer business, and subject us to additional regulatory scrutiny and possible financial liability, any of which could have a material adverse effect on our business, financial condition and results of operations. In addition, failure of third parties to comply with applicable laws and regulations, or fraud or misconduct on the part of employees of any of these third parties could disrupt our operations or adversely affect our reputation.

We are subject to cybersecurity risks and security breaches and may incur increasing costs in an effort to minimize those risks and to respond to cyber incidents, and we may experience harm to our reputation and liability exposure from security breaches.

Our business involves the storage and transmission of consumers' proprietary information, and security breaches could expose us to a risk of loss or misuse of this information, litigation and potential liability. While we have incurred no material cyber-attacks or security breaches to date, a number of other financial services and other companies have disclosed cyber-attacks and security breaches, some of which have involved intentional attacks. Attacks may be targeted at us, our customers, or both. Although we devote significant resources to maintain, regularly update and backup our systems and processes that are designed to protect the security of our computer systems, software, networks and other technology assets and the confidentiality, integrity and availability of information belonging to us or our customers, our security measures may not be effective against all potential cyber-attacks or security breaches. Despite our efforts to ensure the integrity of our systems, it is possible that we may not be able to anticipate or to implement effective preventive measures against all security breaches of these types, especially because the techniques used change frequently or are not recognized until launched, and because cyber-attacks can originate from a wide variety of sources, including persons who are involved with organized crime or associated with external service providers or who may be linked to terrorist organizations or hostile foreign governments. These risks may increase in the future as we continue to increase our internet-based product offerings and expand our internal usage of web-based products and applications. If an actual or perceived security breach occurs, customer perception of the effectiveness of our security measures could be harmed and could result in the loss of customers.

A successful penetration or circumvention of the security of our systems, including those of third party providers or other financial institutions, or the failure to meet regulatory requirements for security of our systems, could cause serious negative consequences, including significant disruption of our operations, misappropriation of our confidential information or that of our customers, or damage to our computers or systems or those of our customers or counterparties, significant increases in compliance costs (such as repairing systems or adding new personnel or protection technologies), and could result in violations of applicable privacy and other laws, financial loss to us or to our customers, loss of confidence in our security measures, customer dissatisfaction, significant litigation and regulatory exposure, and harm to our reputation, all of which could have a material adverse effect on our business, financial condition and results of operations.

Failure to keep up with the rapid technological changes in the financial services industry could have a material adverse effect on our competitive position and profitability.

The financial services industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and reduce costs. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements than we have. We may not be able to implement new technology-driven products and services effectively or be successful in marketing these products and services to our customers. Failure to successfully keep pace with technological change affecting the financial services industry could harm our ability to compete effectively and could have a material adverse effect on our business, financial condition or results of operations. As these technologies are improved in the future, we may be required to make significant capital expenditures in order to remain competitive, which may increase our overall expenses and have a material adverse effect on our business, financial condition and results of operations.

Our risk management framework may not be effective in mitigating risks and/or losses to us.

Our risk management framework is comprised of various processes, systems and strategies, and is designed to manage the types of risk to which we are subject, including, among others, credit, market, liquidity, interest rate and compliance. Our framework also includes financial or other modeling methodologies that involve management assumptions and judgment. Our risk management framework may not be effective under all circumstances. Our risk management framework may not adequately mitigate any risk or loss to us. If our risk management framework is not effective, we could suffer unexpected losses and our business, financial condition, results of operations or growth prospects could be materially and adversely affected. We may also be subject to potentially adverse regulatory consequences.

We may be adversely affected by the soundness of other financial institutions.

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services companies are interrelated as a result of trading, clearing, counterparty, and other relationships. As a result, defaults by, or even rumors or questions about, one or more financial services companies, or the financial services industry generally, could lead to market-wide liquidity problems and losses or defaults by us or other institutions. These losses could have a material adverse effect on our business, financial condition and results of operations.

The requirements of being a public company may strain our resources and divert management's attention.

As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and applicable securities rules and regulations. These laws and regulations increase the scope, complexity and cost of corporate governance, reporting and disclosure practices over those of non-public or non-reporting companies. Despite our conducting business in a highly regulated environment, these laws and regulations have different requirements for compliance than we have experienced prior to becoming a public company. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and operating results and maintain effective disclosure controls and procedures and internal control over financial reporting. As a NASDAQ listed company, we will be required to prepare and file proxy materials which meet the requirements of the Exchange Act and the SEC's proxy rules. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly, and increase demand on our systems and resources, particularly after we are no longer an "emerging growth company" as defined in the JOBS Act. In order to maintain, appropriately document and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet the standards required by the Sarbanes-Oxley Act, significant resources and management oversight may be required. As a result, management's attention may be diverted from other business concerns, which could harm our business and operating results. Additionally, any failure by us to file our periodic reports with the SEC in a timely manner could harm our reputation and cause our investors and potential investors to lose confidence in us, and restrict trading in, and reduce the market price of, our common stock, and potentially availability to access the capital markets.

We are dependent on the use of data and modeling in both our management's decision making generally and in meeting regulatory expectations in particular.

The use of statistical and quantitative models and other quantitatively-based analyses is endemic to bank decision making and regulatory compliance processes, and the employment of such analyses is becoming increasingly widespread in our operations. Liquidity stress testing, interest rate sensitivity analysis, allowance for loan loss measurement, portfolio stress testing and the identification of possible violations of

Table of Contents

anti-money laundering regulations are examples of areas in which we are dependent on models and the data that underlies them. We anticipate that model-derived insights will be used more widely in our decision making in the future. While these quantitative techniques and approaches improve our decision making, they also create the possibility that faulty data or flawed quantitative approaches could yield adverse outcomes or regulatory scrutiny. Secondarily, because of the complexity inherent in these approaches, misunderstanding or misuse of their outputs could similarly result in suboptimal decision making, which could have a material adverse effect on our business, financial condition and results of operations.

If we fail to design, implement and maintain effective internal control over financial reporting or remediate any future material weakness in our internal control over financial reporting, we may be unable to accurately report our financial results or prevent fraud, which could have a material adverse effect on us.

Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of the financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Effective internal control over financial reporting is necessary for us to provide reliable reports and prevent fraud.

We believe that a control system, no matter how well designed and managed, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. We may not be able to identify all significant deficiencies and/or material weaknesses in our internal control in the future, and our failure to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business, financial condition and results of operations.

We may need to raise additional capital in the future, and we may not be able to do so.

Access to sufficient capital is critical in order to enable us to implement our business plan, support our business, expand our operations, and meet applicable capital requirements. The inability to have sufficient capital, whether internally generated through earnings or raised in the capital markets, could adversely impact our ability to support and to grow our operations. If we grow our operations faster than we generate capital internally, we will need to access the capital markets. We may not be able to raise additional capital in the form of additional debt or equity. Our ability to raise additional capital, if needed, will depend on, among other things, conditions in the capital markets at that time, our financial condition and our results of operations. Economic conditions and a loss of confidence in financial institutions may increase our cost of capital and limit access to some sources of capital. Such capital may not be available on acceptable terms, or at all. Any occurrence that may limit our access to the capital markets, or disruption in capital markets, may adversely affect our capital costs and our ability to raise capital. Further, if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and would then have to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when needed could have a material adverse impact on our business, financial condition and results of operations.

We could be subject to environmental risks and associated costs on our foreclosed real estate assets.

Our loan portfolio is secured by real property. During the ordinary course of business, we may foreclose on and take title to properties securing loans. There is a risk that hazardous or toxic substances could be found on these properties and that we could be liable for remediation costs, as well as personal injury and

Table of Contents

property damage. Environmental laws may require us to incur substantial expenses and may materially reduce the affected property's value or limit our ability to sell the affected property. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on our business, financial condition and results of operations.

Litigation and regulatory actions, including possible enforcement actions, could subject us to significant fines, penalties, judgments or other requirements resulting in increased expenses or restrictions on our business activities.

In the normal course of business, from time to time, we have in the past and may in the future be named as a defendant in various legal actions, arising in connection with our current and/or prior business activities. Legal actions could include claims for substantial compensatory or punitive damages or claims for indeterminate amounts of damages. Further we may in the future be subject to consent orders with our regulators. We may also, from time to time, be the subject of subpoenas, requests for information, reviews, investigations and proceedings (both formal and informal) by governmental agencies regarding our current and/or prior business activities. Any such legal or regulatory actions may subject us to substantial compensatory or punitive damages, significant fines, penalties, obligations to change our business practices or other requirements resulting in increased expenses, diminished income and damage to our reputation. Our involvement in any such matters, whether tangential or otherwise and even if the matters are ultimately determined in our favor, could also cause significant harm to our reputation and divert management attention from the operation of our business. Further, any settlement, consent order or adverse judgment in connection with any formal or informal proceeding or investigation by government agencies may result in litigation, investigations or proceedings as other litigants and government agencies begin independent reviews of the same activities. As a result, the outcome of legal and regulatory actions could have a material adverse effect on our business, results of operations and results of operations.

The appraisals and other valuation techniques we use in evaluating and monitoring loans secured by real property and other real estate owned may not accurately reflect the net value of the asset.

In considering whether to make a loan secured by real property, we generally require an appraisal of the property. However, an appraisal is only an estimate of the value of the property at the time the appraisal is made, and, as real estate values may change significantly in value in relatively short periods of time (especially in periods of heightened economic uncertainty), this estimate may not accurately reflect the net value of the collateral after the loan is made. As a result, we may not be able to realize the full amount of any remaining indebtedness when we foreclose on and sell the relevant property. In addition, we rely on appraisals and other valuation techniques to establish the value of REO, that we acquire through foreclosure proceedings and to determine loan impairments. If any of these valuations are inaccurate, our financial statements may not reflect the correct value of our REO, if any, and our allowance for loan losses may not reflect accurate loan impairments. Inaccurate valuation of REO or inaccurate provisioning for loan losses could have a material adverse effect on our business, financial condition and results of operations.

We are subject to an extensive body of accounting rules and best practices. Periodic changes to such rules may change the treatment and recognition of critical financial line items and affect our profitability.

The nature of our business makes us sensitive to the large body of accounting rules in the U.S. From time to time, the governing bodies that oversee changes to accounting rules and reporting requirements may release new guidance for the preparation of our financial statements. These changes can materially impact how we record and report our financial condition and results of operations. In some instances, we could be required to apply a new or revised standard retroactively, resulting in the restatement of prior period financial statements. Changes which have been approved for future implementation, or which are currently proposed or expected to be proposed or adopted include requirements that we: (i) calculate the allowance

Table of Contents

for loan losses on the basis of the current expected loan losses over the lifetime of our loans, which is expected to be applicable to us beginning in 2021, and may result in increases in our allowance for loan losses and future provisions for loan losses; and (ii) record the value of and liabilities relating to operating leases on our balance sheet, which is expected to be applicable beginning in 2019. These changes could adversely affect our capital, regulatory capital ratios, ability to make larger loans, earnings and performance metrics. Any such changes could have a material adverse effect on our business, financial condition and results of operations.

The fair value of our investment securities can fluctuate due to factors outside of our control.

As of September 30, 2017, the fair value of our investment securities portfolio was approximately $483 million. As of the same date, 97% of our investments were U.S. government or U.S. government agency securities. Factors beyond our control can significantly influence the fair value of securities in our portfolio and can cause potential adverse changes to the fair value of these securities. These factors include, but are not limited to, rating agency actions in respect of the securities, defaults by the issuer or with respect to the underlying securities, and changes in market interest rates and instability in the capital markets. Any of these factors, among others, could cause other-than-temporary impairments, or OTTI, and realized and/or unrealized losses in future periods and declines in other comprehensive income, which could materially and adversely affect our business, financial condition or results of operations. The process for determining whether impairment of a security is OTTI usually requires complex, subjective judgments about the future financial performance and liquidity of the issuer, any collateral underlying the security and our intent and ability to hold the security for a sufficient period of time to allow for any anticipated recovery in fair value, in order to assess the probability of receiving all contractual principal and interest payments on the security. Our failure to correctly and timely assess any impairments or losses with respect to our securities could have a material adverse effect on our business, financial condition or results of operations.

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR may adversely affect our results of operations.

Regulators and law enforcement agencies in a number of countries are conducting civil and criminal investigations into whether the banks that contribute to the British Bankers' Association (the "BBA") in connection with the calculation of LIBOR may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR. Actions by the BBA, regulators or law enforcement agencies may result in changes to the manner in which LIBOR is determined or the establishment of alternative reference rates. At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the value of LIBOR-based loans and securities in our portfolio, and may impact the availability and cost of hedging instruments and borrowings. If LIBOR rates are no longer available, and we are required to implement substitute indices for the calculation of interest rates under our loan agreements with our borrowers, we may incur significant expenses in effecting the transition, and may be subject to disputes or litigation with customers over the appropriateness or comparability to LIBOR of the substitute indices, which could have an adverse affect on our results of operations.

We may pursue strategic acquisitions in the future, and we may not be able to overcome risks associated with such transactions.

Although we plan to continue to grow our business organically, we may explore opportunities to invest in, or to acquire, other financial institutions and businesses that we believe would complement our existing business. Our investment or acquisition activities could be material to our business and involve a number of risks including the following:

•

investing time and incurring expense associated with identifying and evaluating potential investments or acquisitions and negotiating potential transactions, resulting in our attention being diverted from the operation of our existing business;

•

the lack of history among our management team in working together on acquisitions and related integration activities;

•

the time, expense and difficulty of integrating the operations and personnel of the combined businesses;

•

unexpected asset quality problems with acquired companies;

•

inaccurate estimates and judgments used to evaluate credit, operations, management and market risks with respect to the target institution or assets;

•

risks of impairment to goodwill or other-than-temporary impairment of investment securities;

•

potential exposure to unknown or contingent liabilities of banks and businesses we acquire;

•

an inability to realize expected synergies or returns on investment;

•

potential disruption of our ongoing banking business; and

•

loss of key employees or key customers following our investment or acquisition.

We may not be successful in overcoming these risks or other problems encountered in connection with potential investments or acquisitions. Our inability to overcome these risks could have an adverse effect on our ability to implement our business strategy and enhance shareholder value, which, in turn, could have a material adverse effect on our business, financial condition or results of operations. Additionally, if we record goodwill in connection with any acquisition, our financial condition and results of operation may be adversely affected if that goodwill is determined to be impaired, which would require us to take an impairment charge.

Risks Related to Our Industry

Our industry is highly regulated, and the regulatory framework, together with any future legislative or regulatory changes, may have a materially adverse effect on our operations.

The banking industry is highly regulated and supervised under both federal and state laws and regulations that are intended primarily for the protection of depositors, customers, the public, the banking system as a whole or the FDIC Deposit Insurance Fund, not for the protection of our shareholders and creditors. We are subject to regulation and supervision by the Federal Reserve, and our Bank is subject to regulation and supervision by the FDIC and the California Department of Business Oversight Division of Financial Institutions, or DBO. Compliance with these laws and regulations can be difficult and costly, and changes to laws and regulations can impose additional compliance costs. The Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, which imposes significant regulatory and compliance changes on financial institutions, is an example of this type of federal regulation. The laws and regulations applicable to us govern a variety of matters, including permissible types, amounts and terms of loans and investments we may make, the maximum interest rate that may be charged, the amount of reserves we must hold against deposits we take, the types of deposits we may accept and the rates we may pay on

Table of Contents

such deposits, maintenance of adequate capital and liquidity, changes in control of us and our Bank, transactions between us and our Bank, handling of nonpublic information, restrictions on dividends and establishment of new offices. We must obtain approval from our regulators before engaging in certain activities, and there is risk that such approvals may not be granted, either in a timely manner or at all. These requirements may constrain our operations, and the adoption of new laws and changes to or repeal of existing laws may have a further impact on our business, financial condition and results of operations. Also, the burden imposed by those federal and state regulations may place banks in general, including our Bank in particular, at a competitive disadvantage compared to their non-bank competitors. Our failure to comply with any applicable laws or regulations, or regulatory policies and interpretations of such laws and regulations, could result in sanctions by regulatory agencies, civil money penalties or damage to our reputation, all of which could have a material adverse effect on our business, financial condition and results of operations.

Bank holding companies and financial institutions are extensively regulated and currently face an uncertain regulatory environment. Applicable laws, regulations, interpretations, enforcement policies and accounting principles have been subject to significant changes in recent years, and may be subject to significant future changes. Future changes may have a material adverse effect on our business, financial condition and results of operations.

Federal and state regulatory agencies may adopt changes to their regulations or change the manner in which existing regulations are applied. We cannot predict the substance or effect of pending or future legislation or regulation or the application of laws and regulations to us. Compliance with current and potential regulation, as well as regulatory scrutiny, may significantly increase our costs, impede the efficiency of our internal business processes, require us to increase our regulatory capital, and limit our ability to pursue business opportunities in an efficient manner by requiring us to expend significant time, effort and resources to ensure compliance and respond to any regulatory inquiries or investigations.

In addition, given the current economic and financial environment, regulators may elect to alter standards or the interpretation of the standards used to measure regulatory compliance or to determine the adequacy of liquidity, risk management or other operational practices for financial service companies in a manner that impacts our ability to implement our strategy and could affect us in substantial and unpredictable ways, and could have a material adverse effect on our business, financial condition and results of operations. Furthermore, the regulatory agencies have extremely broad discretion in their interpretation of laws and regulations and their assessment of the quality of our loan portfolio, securities portfolio and other assets. If any regulatory agency's assessment of the quality of our assets, operations, lending practices, investment practices, capital structure or other aspects of our business differs from our assessment, we may be required to take additional charges or undertake, or refrain from taking, actions that could have a material adverse effect on our business, financial condition and results of operations.

Federal and state regulators periodically examine our business and may require us to remediate adverse examination findings or may take enforcement action against us.

The Federal Reserve, the FDIC and the DBO periodically examine our business, including our compliance with laws and regulations. If, as a result of an examination, the Federal Reserve, the FDIC, or the DBO were to determine that our financial condition, capital resources, asset quality, earnings prospects, management, liquidity or other aspects of any of our operations had become unsatisfactory, or that we were in violation of any law or regulation, they may take a number of different remedial actions as they deem appropriate. These actions include the power to require us to remediate any such adverse examination findings.

In addition, these agencies have the power to take enforcement action against us to enjoin "unsafe or unsound" practices, to require affirmative action to correct any conditions resulting from any violation of

Table of Contents

law or regulation or unsafe or unsound practice, to issue an administrative order that can be judicially enforced, to direct an increase in our capital, to direct the sale of subsidiaries or other assets, to limit dividends and distributions, to restrict our growth, to assess civil money penalties against us or our officers or directors, to remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is imminent risk of loss to depositors, to terminate our deposit insurance and place our Bank into receivership or conservatorship. Any regulatory enforcement action against us could have a material adverse effect on our business, financial condition and results of operations.

We may be required to act as a source of financial and managerial strength for our Bank in times of stress.

Under federal law and long-standing Federal Reserve policy, we, as a bank holding company, are required to act as a source of financial and managerial strength to our Bank and to commit resources to support our Bank if necessary. We may be required to commit additional resources to our Bank at times when we may not be in a financial position to provide such resources or when it may not be in our, or our shareholders' or creditors', best interests to do so. A requirement to provide such support is more likely during times of financial stress for us and our Bank, which may make any capital we are required to raise to provide such support more expensive than it might otherwise be. In addition, any capital loans we make to our Bank are subordinate in right of repayment to deposit liabilities of our Bank.

Regulatory initiatives regarding bank capital requirements may require heightened capital.

Regulatory capital rules, adopted in July 2013, implement higher minimum capital requirements for bank holding companies and banks. These rules, which implement the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision, include a common equity Tier 1 capital requirement and establish criteria that instruments must meet to be considered common equity Tier 1 capital, additional Tier 1 capital or Tier 2 capital. These enhancements were intended to both improve the quality and increase the quantity of capital required to be held by banking organizations, and to better equip the U.S. banking system to deal with adverse economic conditions. The capital rules require bank holding companies and banks to maintain a common equity Tier 1 capital ratio of 4.5%, a minimum total Tier 1 risk based capital ratio of 6%, a minimum total risk based capital ratio of 8%, and a minimum leverage ratio of 4%. Bank holding companies and banks are also required to hold a capital conservation buffer of common equity Tier 1 capital of 2.5% (when fully phased in) to avoid limitations on capital distributions and discretionary executive compensation payments. At September 30, 2017, the capital conservation buffer was 1.25%. The revised capital rules will also require banks to maintain a common equity Tier 1 capital ratio of 6.5% or greater, a Tier 1 capital ratio of 8% or greater, a total capital ratio of 10% or greater and a leverage ratio of 5% or greater to be deemed "well-capitalized" for purposes of certain rules and prompt corrective action requirements.

The Federal Reserve may also set higher capital requirements for holding companies whose circumstances warrant it. For example, holding companies experiencing significant internal growth or making acquisitions are expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. Our regulatory capital ratios currently are in excess of the levels established for "well-capitalized" institutions. Future regulatory change could impose higher capital standards.

Any new or revised standards adopted in the future may require us to maintain materially more capital, with common equity as a more predominant component, or manage the configuration of our assets and liabilities to comply with formulaic liquidity requirements. We may not be able to raise additional capital at all, or on terms acceptable to us. Failure to maintain capital to meet current or future regulatory

Table of Contents

requirements could have a significant 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 of 1970, the Uniting and Strengthening America by Providing Appropriate Tools to Intercept and Obstruct Terrorism Act of 2001, or the USA Patriot Act or 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 reports such as suspicious activity reports and currency transaction reports. We are required to comply with these and other anti-money laundering requirements. Our federal and state banking regulators, the Financial Crimes Enforcement Network, or FinCEN, and other government agencies are authorized to impose significant civil money penalties for violations of anti-money laundering requirements. We are also subject to increased scrutiny of compliance with the regulations issued and enforced by the Office of Foreign Assets Control, or OFAC. If our program is deemed deficient, we could be subject to liability, including fines, civil money penalties and other regulatory actions, which may include restrictions on our business operations and our ability to pay dividends, restrictions on mergers and acquisitions activity, restrictions on expansion, and restrictions on entering new business lines. Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have significant reputational consequences for us. Any of these circumstances could have a material adverse effect on our business, financial condition or results of operations.

We are subject to numerous "fair and responsible banking" laws designed to protect consumers, and failure to comply with these laws could lead to a wide variety of sanctions.

The Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act and other fair lending laws and regulations, including state laws and regulations, prohibit discriminatory lending practices by financial institutions. The Federal Trade Commission Act and the Dodd-Frank Act prohibit unfair, deceptive, or abusive acts or practices by financial institutions. The U.S. Department of Justice, or DOJ, federal banking agencies, and other federal and state agencies are responsible for enforcing these fair and responsible banking laws and regulations. In 2012, our Bank, without admitting any wrongdoing, settled a lawsuit by the DOJ alleging violations of fair lending laws in connection with our single family mortgage lending program. The settlement required a number of remedial actions, with which we fully complied within the prescribed three year time frame. A challenge to an institution's compliance with fair and responsible banking laws and regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions activity, restrictions on expansion, and restrictions on entering new business lines. Private parties may also have the ability to challenge an institution's performance under fair lending laws in private class action litigation. Such actions could have a material adverse effect on our reputation, business, financial condition and results of operations.

We are subject to laws regarding the privacy, information security and protection of personal information and any violation of these laws or another incident involving personal, confidential, or proprietary information of individuals could damage our reputation and otherwise adversely affect our business.

Our business requires the collection and retention of large volumes of customer data, including personally identifiable information, or PII, in various information systems that we maintain and in those maintained by third party service providers. We also maintain important internal company data such as PII about our employees and information relating to our operations. We are subject to complex and evolving laws and regulations governing the privacy and protection of PII of individuals (including customers, employees, and other third parties). For example, our business is subject to the Gramm-Leach-Bliley Act, or the GLB Act,

Table of Contents

which, among other things: (i) imposes certain limitations on our ability to share nonpublic PII about our customers with nonaffiliated third parties; (ii) requests that we provide certain disclosures to customers about our information collection, sharing and security practices and afford customers the right to "opt out" of any information sharing by us with nonaffiliated third parties (with certain exceptions); and (iii) requires that we develop, implement and maintain a written comprehensive information security program containing appropriate safeguards based on our size and complexity, the nature and scope of our activities, and the sensitivity of customer information we process, as well as plans for responding to data security breaches. Various federal and state banking regulators and states have also enacted data breach notification requirements with varying levels of individual, consumer, regulatory or law enforcement notification in the event of a security breach. Ensuring that our collection, use, transfer and storage of PII complies with all applicable laws and regulations can increase our costs. Furthermore, we may not be able to ensure that customers and other third parties have appropriate controls in place to protect the confidentiality of the information that they exchange with us, particularly where such information is transmitted by electronic means. If personal, confidential or proprietary information of customers or others were to be mishandled or misused (in situations where, for example, such information was erroneously provided to parties who are not permitted to have the information, or where such information was intercepted or otherwise compromised by third parties), we could be exposed to litigation or regulatory sanctions under privacy and data protection laws and regulations. Concerns regarding the effectiveness of our measures to safeguard PII, or even the perception that such measures are inadequate, could cause us to lose customers or potential customers and thereby reduce our revenues. Accordingly, any failure, or perceived failure to comply with applicable privacy or data protection laws and regulations may subject us to inquiries, examinations and investigations that could result in requirements to modify or cease certain operations or practices or in significant liabilities, fines or penalties, and could damage our reputation and otherwise adversely affect our operations, financial condition and results of operations.

Our use of third party vendors and our other ongoing third party business relationships are subject to increasing regulatory requirements and attention.

We regularly use third party vendors in our business and we rely on some of these vendors for critical functions including, but not limited to, our core processing function and mortgage broker relationships. Third party relationships are subject to increasingly demanding regulatory requirements and attention by bank regulators. We expect our regulators to hold us responsible for deficiencies in our oversight or control of our third party vendor relationships and in the performance of the parties with which we have these relationships. As a result, if our regulators conclude that we have not exercised adequate oversight and control over our third party vendors or that such vendors have not performed adequately, we could be subject to administrative penalties or fines as well as requirements for consumer remediation, any of which could have a material adverse effect on our business, financial condition and results of operations. Additionally, our use of loan brokers to originate a portion of our multifamily residential loans and all of our single family residential loans, exposes us to risk of loss or liability in the event that such brokers misrepresent the borrower's financial condition or other information included in the loan package, or if the broker engages in violations of law in connection with the loan.

Rulemaking changes implemented by the Consumer Financial Protection Bureau will result in higher regulatory and compliance costs that may adversely affect our business.

The Dodd-Frank Act created a new, independent federal agency, the Consumer Financial Protection Bureau, or CFPB, which was granted broad rulemaking, supervisory and enforcement powers under various federal consumer financial protection laws. The CFPB also has examination and primary enforcement authority with respect to depository institutions with assets over $10.0 billion, their third party service providers and non-depository entities such as debt collectors and consumer reporting agencies. The consumer protection provisions of the Dodd-Frank Act and the examination, supervision and enforcement of those laws and

Table of Contents

implementing regulations by the CFPB have created a more intense and complex environment for consumer finance regulation. The ultimate impact of this heightened scrutiny is uncertain but could result in changes to pricing, practices, products and procedures. It could also result in increased costs related to regulatory oversight, supervision and examination. These changes could have a material adverse effect on our business, financial condition and results of operations, even if we remain under the threshold of over $10.0 billion for CFPB supervision.

Potential limitations on incentive compensation contained in proposed federal agency rulemaking may adversely affect our ability to attract and retain our highest performing employees.

In April 2011 and May 2016, the Federal Reserve, other federal banking agencies and the SEC jointly published proposed rules designed to implement provisions of the Dodd-Frank Act prohibiting incentive compensation arrangements that would encourage inappropriate risk taking at covered financial institutions, which includes a bank or bank holding company with $1 billion or more in consolidated assets, such as our Bank. It cannot be determined at this time whether or when a final rule will be adopted and whether compliance with such a final rule will substantially affect the manner in which we structure compensation for our executives and other employees. Depending on the nature and application of the final rules, we may not be able to successfully compete with financial institutions and other companies that are not subject to some or all of the rules to retain and attract executives and other high performing employees.

Our Bank's FDIC deposit insurance premiums and assessments may increase.

Our Bank's deposits are insured by the FDIC up to legal limits and, accordingly, our Bank is subject to insurance assessments based on our Bank's average consolidated total assets less its average tangible equity. Our Bank's regular assessments are determined by its risk classification, which is based on its regulatory capital levels and the level of supervisory concern that it poses. Numerous bank failures during the financial crisis and increases in the statutory deposit insurance limits increased resolution costs to the FDIC and put significant pressure on the Deposit Insurance Fund. In order to maintain a strong funding position and the reserve ratios of the Deposit Insurance Fund required by statute and FDIC estimates of projected requirements, the FDIC has the power to increase deposit insurance assessment rates and impose special assessments on all FDIC-insured financial institutions. Any future increases or special assessments could reduce our profitability and could have a material adverse effect on our business, financial condition, and results of operations.

Risks Related to an Investment in Our Common Stock and the Offering

No prior public market exists for our common stock, and one may not develop.

Prior to this offering there has been no public market for our common stock. An active trading market for shares of our common stock may never develop or may not be sustained following this offering. If an active trading market does not develop, you may have difficulty selling your shares of common stock. The initial public offering price for our common stock will be determined by negotiations between us and the representatives of the underwriters. This price may not be indicative of the price at which our common stock will trade after the offering. The market price of our common stock may decline below the initial offering price, and you may not be able to sell your common stock at or above the price you paid in this offering, or at all. An inactive market may also impair our ability to raise capital by selling our common stock and may impair our ability to expand our business through acquisitions, by using our common stock as consideration, should we elect to do so.

Table of Contents

Our stock price may be volatile, and you could lose part or all of your investment as a result.

Stock price volatility may negatively impact the price at which our common stock may be sold, and may also negatively impact the timing of any sale. Our stock price may fluctuate widely in response to a variety of factors including the risk factors described herein and, among other things:

•

actual or anticipated variations in quarterly operating results, financial conditions or credit quality;

•

changes in business or economic conditions;

•

recommendations or research reports about us or the financial services industry in general published by securities analysts;

•

the failure of securities analysts to cover, or to continue cover, us after this offering;

•

changes in financial estimates or publication of research reports and recommendations by financial analysts or actions taken by rating agencies with respect to us or other financial institutions;

•

news reports relating to trends, concerns and other issues in the financial services industry;

•

reports related to the impact of natural or man made disasters in our markets;

•

perceptions in the marketplace regarding us and or our competitors;

•

significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or involving us or our competitors;

•

additional investments from third parties;

•

additions or departures of key personnel;

•

future sales or issuance of additional shares of stock;

•

fluctuations in the stock price and operating results of our competitors;

•

changes or proposed changes in laws or regulations, or differing interpretations thereof affecting our business, or enforcement of these laws or regulations;

•

new technology used, or services offered, by competitors;

•

additional investments from third parties; or

•

geopolitical conditions such as acts or threats of terrorism, pandemics or military conflicts.

The market price of our stock could be negatively affected by sales of substantial amounts of our common stock in the public markets.

Sales of a substantial number of shares of our common stock in the public market following this offering, or the perception that large sales could occur, could cause the market price of our common stock to decline or limit our future ability to raise capital through an offering of equity securities.

After this offering, there will be 53,350,000 shares of our common stock outstanding (or 55,052,500 shares outstanding if the underwriters exercise their option to purchase additional shares in full). Of our issued and outstanding shares of common stock, all the shares sold in this offering will be freely transferable, except for any shares held by our "affiliates," as that term is defined in Rule 144 under the Securities Act, in respect of which the applicable holding period has not yet passed. Following completion of this offering, approximately 74.98% of our outstanding common stock (or 72.66% if the underwriters exercise their option to purchase additional shares in full) will be held by the Trione Family Trusts and can be resold into the public markets in the future in accordance with the requirements of Rule 144. An additional 3.75% of the shares of common stock outstanding after completion of the offering (3.63% if the underwriters exercise their option to purchase additional shares in full) held by other shareholders will be eligible for resale into the public markets in accordance with Rule 144.

Table of Contents

We, our executive officers and directors, and shareholders owning in excess of 95% of the currently outstanding shares of common stock have agreed with the underwriters that, subject to exceptions, we and they will not directly or indirectly sell or otherwise transfer their shares for a period of 180 days after the date of this prospectus.

The market price for our common stock may decline significantly when the restrictions on resale by our existing shareholders lapse. A decline in the price of our common stock might impede our ability to raise capital through the issuance of additional common stock or other equity securities.

Investors in this offering will experience immediate and substantial dilution.

The initial public offering price of our stock is substantially higher than the net tangible book value per share of our common stock immediately following the offering. Therefore, if you purchase shares in this offering, you will experience immediate and substantial dilution in net tangible book value per share in relation to the price that you paid for your shares. Based on the initial public offering price of $11.50 per share and our net tangible book value as of September 30, 2017, if you purchase our common stock in this offering, you will suffer immediate dilution of approximately $2.01$1.98 per share in net tangible book value. As a result of this dilution, investors purchasing stock in this offering may receive significantly less than the full purchase price that they paid for the shares purchased in this offering in the event of a liquidation.

We are an "emerging growth company," as defined in the JOBS Act and will be able to avail ourselves of reduced disclosure requirements applicable to emerging growth companies, which could make our common stock less attractive to investors and adversely affect the market price of our common stock.

We are an "emerging growth company," as defined in the JOBS Act. For as long as we continue to be an emerging growth company we may take advantage of certain exemptions from various requirements generally applicable to public companies. These include, without limitation, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, reduced financial reporting requirements, reduced disclosure obligations regarding executive compensation, and exemption from requirements of holding non-binding advisory votes on executive compensation and golden parachute payments. The JOBS Act also permits an emerging growth company such as us to take advantage of an extended transition period to comply with the new or revised accounting standards applicable to public companies. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. The election not to opt out of the extended transition period may cause our financial condition and results of operations to be less comparable to those of other companies.

We may take advantage of these exemptions until we are no longer an emerging growth company. We would cease to be an emerging growth company upon the earliest of: (i) the first fiscal year following the fifth anniversary of this offering; (ii) the first fiscal year after our annual gross revenues are $1.07 billion or more; (iii) the date on which we have during the previous three-year period, issued more than $1 billion in non-convertible debt securities; or (iv) as of the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeds $700 million as of the end of the second quarter of that fiscal year.

We cannot predict whether investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may a less active trading market for our common stock, and our stock price may be more volatile or decline.

Table of Contents

Securities analysts may not initiate or continue coverage on our common stock, which could adversely affect the market for our common stock.

The trading market for our common stock will depend in part on the research and reports that securities analysts publish about us and our business. We do not have any control over these securities analysts, and they may not cover our common stock. If securities analysts do not cover our common stock, the lack of research coverage may adversely affect its market price. If we are covered by securities analysts, and our common stock is the subject of an unfavorable report, the price of our common stock may decline. If one or more of these analysts ceases to cover us or fails to publish regular reports on us, the price or trading volume of our common stock could decline as a result.

We have broad discretion in allocating the net proceeds of the offering. Our failure to effectively utilize such net proceeds may have an adverse effect on our financial performance and the value of our common stock.

We intend to use the net proceeds of this offering after the distributions to our existing shareholders to increase the capital of the Bank in order to support our organic growth and implement our strategic initiatives, for working capital and for other general corporate purposes, and to strengthen our regulatory capital. We have not designated the amount of net proceeds that we will contribute to the Bank or that we will use for any particular purpose. Accordingly, our management will have broad discretion in the application of the net proceeds from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. You will not have the opportunity, as part of your investment decision, to assess whether we are using the proceeds appropriately. Our management might not apply our net proceeds in ways that ultimately increase the value of your investment. If we do not invest or apply the net proceeds from this offering in ways that enhance shareholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

There are substantial regulatory limitations on changes of control of bank holding companies that may discourage investors from purchasing shares of our common stock.

With limited exceptions, federal regulations prohibit a person or company or a group of persons deemed to be "acting in concert" from, directly or indirectly, acquiring more than 10% (5% if the acquirer is a bank holding company) of any class of our voting stock or obtaining the ability to control in any manner the election of a majority of the directors or otherwise direct the management or policies of our company without prior notice or application to, and the approval of, the Federal Reserve. Companies investing in banks and bank holding companies receive additional review and may be required to become bank holding companies, subject to regulatory supervision. Accordingly, prospective investors must be aware of and comply with these requirements, if applicable, in connection with any purchase of shares of our common stock. These provisions could discourage third parties from seeking to acquire significant interests in us or in attempting to acquire control of us, which, in turn, could adversely affect the market price of our common stock.

As a public company, we will incur significant legal, accounting, insurance, compliance and other expenses. Any deficiencies in our financial reporting or internal controls could materially and adversely affect our business and the market price of our common stock.

As a public company, we will incur significant legal, accounting, insurance and other expenses. These costs and compliance with the rules of the SEC and the rules of NASDAQ will increase our legal and financial compliance costs and make some activities more time consuming and costly. Beginning with our Annual Report on Form 10-K for our 2018 fiscal year, SEC rules will require that our Chief Executive Officer and Chief Financial Officer periodically certify the existence and effectiveness of our internal control over

Table of Contents

financial reporting. Beginning with the time we are no longer an "emerging growth company" as defined in the JOBS Act, but no later than December 31, 2022, we will be required to engage our independent registered public accounting firm to audit and opine on the design and operating effectiveness of our internal control over financial reporting. This process will require significant documentation of policies, procedures and systems, and review of that documentation and testing of our internal control over financial reporting by our internal auditing and accounting staff and our independent registered public accounting firm. This process will require considerable time and attention from management, which could prevent us from successfully implementing our business initiatives and improving our business, financial condition and results of operations, any strain our internal resources, and will increase our operating costs. We may experience higher than anticipated operating expenses and outside auditor fees during the implementation of these changes and thereafter.

During the course of our testing we may identify deficiencies that would have to be remediated to satisfy the SEC rules for certification of our internal control over financial reporting. A material weakness is defined by the standards issued by the PCAOB as a deficiency, or combination of deficiencies, in internal control over financial reporting that results in a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a consequence, we would have to disclose in periodic reports we file with the SEC any material weakness in our internal control over financial reporting. The existence of a material weakness would preclude management from concluding that our internal control over financial reporting is effective and would preclude our independent auditors from expressing an unqualified opinion on the effectiveness of our internal control over financial reporting. In addition, disclosures of deficiencies of this type in our SEC reports could cause investors to lose confidence in our financial reporting, and may negatively affect the market price of our common stock, and could result in the delisting of our securities from the securities exchanges on which they trade. Moreover, effective internal controls are necessary to produce reliable financial reports and to prevent fraud. If we have deficiencies in our disclosure controls and procedures or internal control over financial reporting, it may materially and adversely affect us.

We may not pay dividends on our common stock in the future.

Holders of our common stock are entitled to receive only such dividends as our board of directors may declare out of funds legally available for such payments. Our board of directors may, in its sole discretion, change the amount or frequency of dividends or discontinue the payment of dividends entirely. In addition, we are a bank holding company, and our ability to declare and pay dividends is dependent on federal regulatory considerations, including the guidelines of the Federal Reserve regarding capital adequacy and dividends. It is the policy of the Federal Reserve that bank holding companies should generally pay dividends on common stock only out of earnings, and only if prospective earnings retention is consistent with the organization's expected future needs, asset quality and financial condition.

We are controlled by trusts established for the benefit of members of the Trione family, whose interests in our business may be different from yours.

Trusts established for the benefit of the Chairman of our board of directors, Victor S. Trione, our former director and Secretary, Mark Trione and his wife, and each of the adult children of Messrs. Trione, collectively referred to as the Trione Family Trusts, currently control 95.2% of our common stock and if they vote in the same manner, are able to control our affairs in all circumstances. The Trione Family Trusts established for the benefit of the adult children hold an aggregate of 59.0% of the common stock outstanding before this offering, and each has the same third party trustees, one of whom is an employee of a company owned by Messrs. Trione. Following this offering, the Trione Family Trusts will continue to own approximately 74.97% of our common stock (or 72.66% if the underwriters exercise their option to purchase additional shares in full). As a result, the Trione Family Trusts will continue, if they vote in the

Table of Contents

same manner, to have the ability to determine the outcome of all matters put to a shareholder vote, including the election of directors, the approval of mergers, material acquisitions and dispositions and other extraordinary transactions, and amendments to our articles of incorporation, bylaws and other corporate governance documents. So long as the Trione Family Trusts continue to own a majority of our common stock, they will have the ability, if they vote in the same manner, to prevent any transaction that requires shareholder approval regardless of whether others believe the transaction is in our best interests. In any of these matters, the interests of the Trione Family Trusts may differ from or conflict with the interests of our other shareholders. Moreover, this concentration of stock ownership may also adversely affect the trading price of our common stock, if investors perceive disadvantages in owning stock of a company with a controlling family.

We are a "controlled company" within the meaning of the rules of NASDAQ and, as a result, qualify for, and may rely on, exemptions from certain corporate governance requirements. As a result, you will not have the same protections afforded to shareholders of companies that are subject to such requirements.

Following the consummation of this offering, The Trione Family Trusts will continue to control a majority of the voting power of our outstanding common stock. As a result, we will be a "controlled company" within the meaning of the corporate governance standards of NASDAQ. Under these rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements, including the requirements that a majority of the board of directors consist of independent directors and to have board-level compensation and nominating and corporate governance committees consisting entirely of independent directors.

Following this offering, we do not intend to rely on these exemptions, but we may, in the future, take advantage of some of these exemptions for as long as we continue to qualify as a "controlled company." Accordingly, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of NASDAQ.

We may issue additional equity securities, or engage in other transactions, which could affect the priority of our common stock, which may adversely affect the market price of our common stock.

Our board of directors may determine from time to time that we need to raise additional capital by issuing additional shares of our common stock or other securities. We are not restricted from issuing additional shares of common stock, including securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future offerings, or the prices at which such offerings may be effected. Such offerings could be dilutive to common shareholders. We may also issue shares of preferred stock that will provide new investors with rights, preferences and privileges that are senior to, and that adversely affect, our then current common shareholders. Additionally, if we raise additional capital by making additional offerings of debt or preferred equity securities, upon liquidation, holders of our debt securities and shares of preferred stock, and lenders with respect to other borrowings, will receive distributions of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing shareholders or reduce the market price of our common stock, or both. Holders of our common stock are not entitled to preemptive rights or other protections against dilution.

We intend to enter into a tax sharing agreement with our existing shareholders and could become obligated to make payments to our existing shareholders for any additional federal, state or local income taxes assessed against them for tax periods prior to the completion of this offering.

We historically have been treated as an S Corporation for U.S. federal income tax purposes. Because we have been an S Corporation our existing shareholders have been taxed on our income as individuals. Therefore our existing shareholders have received distributions, referred to as tax distributions, from us that were generally intended to equal the amount of tax the existing shareholders were required to pay with respect to our income. In connection with this offering, our S Corporation status will terminate and we will thereafter be subject to federal and increased state income taxes. In the event of an adjustment to our reported taxable income for periods prior to the termination of our S Corporation status, it is possible that our existing shareholders would be liable for additional income taxes for those prior periods. Therefore, we intend to enter into an agreement with our existing shareholders prior to completion of this offering. Pursuant to this agreement, upon our filing of any tax return (amended or otherwise), in the event of any restatement of our taxable income pursuant to a determination by, or a settlement with, a taxing authority, for any period during which we were an S Corporation, depending on the nature of the adjustment we may be required to make a payment to our existing shareholders in an amount equal to our existing shareholders' incremental tax liability, which amount may be material. In addition, we will indemnify our existing shareholders with respect to unpaid income tax liabilities to the extent that such unpaid income tax liabilities are attributable to an adjustment to our taxable income for any period after our S Corporation status terminates. In both cases the amount of the payment will be based on the assumption that our existing shareholders are taxed at the highest rate application to married individuals filing jointly for the relevant periods. We will also indemnify our existing shareholders for any interest, penalties, losses, costs or expenses arising out of any claim under the agreement. However, our existing shareholders will indemnify us with respect to our unpaid tax liabilities (including interest and penalties) to the extent that such unpaid tax liabilities are attributable to a decrease in our existing shareholders' taxable income for any tax period and a corresponding increase in our taxable income for any period.

Prior to this offering, we were treated as an S Corporation, and claims of taxing authorities related to our prior status as an S Corporation could adversely affect us.

Upon consummation of this offering, our status as an S Corporation will terminate and we will be treated as a "C Corporation" under the provisions of Sections 301 through 385 of the Code, which treat the corporation as an entity that is subject to U.S. federal income tax. If the unaudited, open tax years in which we were an S Corporation are audited by the Internal Revenue Service, or IRS, and we are determined not to have qualified for, or to have violated any requirement for maintaining, our S Corporation status, we will be obligated to pay back taxes, interest and penalties. The amounts that we would be obligated to pay could include taxes on all our taxable income while we were an S Corporation. Any such claims could result in additional costs to us and could have a material adverse effect on our business, financial condition or results of operations. For information regarding our pro forma tax liabilities if we had been taxed as a C Corporation, see "Selected Historical and Pro Forma Financial Data".

Future equity issuances could result in dilution, which could cause our common stock price to decline and future sales of our common stock could depress the market price of our common stock.

Following the completion of this offering, we will have 53,350,000 issued and outstanding shares of our common stock (55,052,500 shares if the underwriters elect to their option to purchase additional shares of common stock in full). Although we do not currently have any plans, arrangements or understandings to issue any shares of our common stock during the twelve month period following the date of this registration statement other than pursuant to the equity compensation arrangements described in this registration statement, actual or anticipated issuances or sales of substantial amounts of our common stock
