Current report

Our stress tests may not accurately predict our financial condition.

Current report

We perform credit and capital stress testing on an quarterly basis using stress test assumptions we believe are reasonable. Within our stress test, we estimate our credit losses, resources available to absorb those losses, and any necessary additions to capital. The results of these stress tests involve many assumptions about the future economy, credit losses and default rates and may not accurately reflect our financial condition. Any deterioration in the economy could result in significantly higher credit losses and negative impacts on our financial condition and capital than projected by our internal stress tests.

Current report

Our adoption and use of artificial intelligence, including generative artificial intelligence, machine learning, and similar tools and technologies that collect, aggregate, analyze or generate data or other materials or content (collectively, "AI"), for internal use has increased our efficiency, and we expect to continue to adopt such tools as appropriate, in line with our AI Strategy. In addition, we expect our third-party vendors and service providers to increasingly develop and incorporate AI into their product offerings faster than we are able to do so independently. The adoption and incorporation of such AI tools can lead to concerns around safety and soundness, fair access to financial services, fair treatment of consumers, and compliance with applicable laws and regulations. We have implemented an AI governance function and risk management framework that includes a risk assessment of internal and vendor AI solutions, due diligence, and controls.

Current report

In addition, regulation of AI is rapidly evolving as legislatures and regulators are increasingly focused on these powerful emerging technologies. The technologies underlying AI and its uses are subject to a variety of laws and regulations, including intellectual property, data privacy and cybersecurity, consumer protection, competition, equal opportunity, and fair lending laws, and are expected to be subject to increased regulation and new laws or new applications of existing laws and regulations. AI is the subject of ongoing review by various U.S. governmental and regulatory agencies, and various U.S. states are applying, or are considering applying, existing laws and regulations to AI or are considering general legal frameworks for AI. We may not be able to anticipate how to respond to these rapidly evolving frameworks, and we may need to expend resources to adjust our operations or offerings in certain jurisdictions if the legal frameworks are inconsistent across jurisdictions. Furthermore, because AI technology itself is highly complex and rapidly developing, it is not possible to predict all the legal, operational or technological risks that may arise relating to the use of AI. Our use of AI may require additional resources, including the incurrence of additional costs, to develop and maintain our products and services to minimize potentially harmful or unintended consequences, to comply with applicable and emerging laws and regulations, to maintain or extend our competitive position, and to address any ethical, reputational, technical, operational, legal, competitive or regulatory issues which may arise as a result of any of the foregoing.

Previous report

Payments Services. In 2016, we added a new funding source by way of facilitating payment services. We are continuing to identify and solicit new customers in need of these specialized services. The primary reasons for expanding into payment services are to secure an additional source of low-cost deposits and to capture additional fee income. A bank’s risks when dealing with a processor account are similar to risks from other activities in which customers conduct transactions through the bank on behalf of the customers’ clients. It is necessary for a bank to implement an adequate processor approval, monitoring and auditing program that extends beyond credit risk management and is conducted on an ongoing basis. When a bank is not able to identify and understand the nature and source of transactions processed through accounts, the bank’s risks and the likelihood of suspicious activity can increase. Without these precautions, a bank could be vulnerable to processing illicit or sanctioned transactions.

Previous report

BAAS Software Solutions. Developing and deploying a software program has added, and may contain to add, additional risk, including financial, cybersecurity, compliance and reputational concerns.

Previous report

In 2021, the Company began development of a proprietary BAAS solution, Avenu, to provide an embedded banking solution that connects our partners (fintech, application developers, money movers, and entrepreneurs) directly and seamlessly to our Software as a Service (SAAS). At the end of 2024, management reviewed the Avenu platform’s performance. Delays in bringing Avenu to market and subsequent changes in revenue generation potential necessitated a review for impairment and a resulting charge to earnings of the full value of its capitalized intangible software. For additional information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Previous report

COVID-19 and its variants have not been completely eliminated.

Previous report

The Company has resumed pre-COVID-19 pandemic business activities, and our employees have returned to the office. The Bank’s branch offices are open and operating during normal business hours. To protect the health of its customers and employees, the Company continues to take precautions. Those actions have not impaired our ability to conduct business and fully serve our customers. While the adverse impacts of the COVID-19 pandemic have dissipated, COVID-19 and its variants have not been completely eliminated. New variants could adversely disrupt our future operations.

Previous report

Prior to 2022, it had been the policy of the Federal Reserve to maintain interest rates at historically low levels through its targeted federal funds rate and the purchase of mortgage-backed securities. As a result, market rates on the loans we originated and the yields on securities we purchased during that period have been at historically low levels. As discussed above, rates are fluctuating, and due to a number of factors including changes in monetary policies of the Federal Reserve, will likely continue to fluctuate.

Previous wording

A substantial portion of our loan portfolio consists of commercial and residential real estate-related loans, including construction and residential and commercial mortgage loans. As of December 31, 2024, we had approximately $357.7 million of owner-occupied and $560.1 million of investment commercial real estate loans outstanding, which represented approximately 19.5% and 30.5%, respectively, of our loan portfolio as of December 31, 2024. As of that same date, we had approximately $393.4 million of construction real estate loans and $439.5 million of residential real estate loans, which represented 21.4% and 23.9% respectively.

Current wording

A substantial portion of our loan portfolio consists of commercial and residential real estate-related loans, including construction and residential and commercial mortgage loans. As of December 31, 2025, we had approximately $448.5 million of owner-occupied and $566.4 million of investment commercial real estate loans outstanding, which represented approximately 24.0% and 30.4%, respectively, of our loan portfolio as of December 31, 2025. As of that same date, we had approximately $300.7 million of construction real estate loans and $441.6 million of residential real estate loans, which represented 16.1% and 23.7% respectively.

Previous wording

In recent years commercial real estate markets both nationally and locally have been adversely affected by the COVID-19 pandemic. Remote employee work opportunities during the pandemic have impacted, and may continue to impact, the occupancy of commercial properties. Weakness in our commercial real estate market could result in an increased delinquency rate and losses from these loans. We believe that the resilience of our market and borrowers provides an ability to adjust to and withstand such risks. However, increased losses from this portfolio could have an adverse effect on our business, financial condition and results of operations.

Weakness in our commercial real estate market could result in increased delinquency rate and losses from these loans. We believe that the resilience of our market and borrowers provides an ability to adjust to and withstand such risks. However, increased losses from this portfolio could have an adverse effect on our business, financial condition and results of operations.

Previous wording

A commitment to extend credit is a formal agreement to lend funds to a customer as long as there is no violation of any condition established under the agreement. The actual borrowing needs of our customers under these credit commitments have historically been lower than the contractual amount of the commitments. A significant portion of these commitments expire without being drawn upon. Because of the credit profile of our customers, we typically have a substantial amount of total unfunded credit commitments, which is not reflected on our balance sheet. As of December 31, 2024, we had $232.6 million in unfunded credit commitments to our customers. Actual borrowing needs of our customers may exceed our expectations, especially during a challenging economic environment when our customers may be more dependent on our credit commitments due to the lack of available credit elsewhere, the increasing costs of credit, or the limited availability of financings from venture firms. This could adversely affect our liquidity, which could impair our ability to fund operations and meet obligations as they become due and could have a material adverse effect on our business, financial condition and results of operations.

Previous wording

We may be required to increase our provisions for credit losses and to charge off loans in the future, which increases in provision and charges could materially adversely affect us.

Current wording

We may be required to increase our provisions for credit losses and to charge off loans in the future; increases in provision and charge offs could materially adversely affect us.

Previous wording

There is no precise method of predicting the timing of loan losses. We can give no assurance that our allowance for credit losses is or will be sufficient to absorb actual loan losses. We maintain an allowance for credit losses on loans, which is a reserve established through a provision for credit losses charged to expense, that represents management’s estimable and observable losses within the existing portfolio of loans. The level of the allowance reflects management’s evaluation of, among other factors, the status of specific individually evaluated loans, trends in historical loss experience, delinquency trends, credit concentrations and economic conditions within our market area. The determination of the appropriate level of the allowance for credit losses inherently involves a high degree of subjectivity and judgment and requires us to make significant estimates of current and expected future credit risks and future trends, any or all of which may undergo subsequent material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may require us to increase our allowance for credit losses. Increases in nonperforming loans have a significant impact on our allowance for credit losses.

Previous wording

Among other sources of funds, we rely heavily on deposits for funds to make loans and provide for our other liquidity needs. However, our loan demand has historically exceeded the rate at which we have been able to build core deposits for which there is substantial competition from a variety of different competitors, so we have relied on interest-sensitive deposits, including wholesale deposits, as sources of funds. Those deposits may not be as stable as other types of deposits and, in the future, depositors may not renew those deposits when they mature, or we may have to pay a higher rate of interest to attract or retain them or to replace them with other deposits or with funds from other sources. Not being able to attract deposits, or to retain or replace them as they mature, would adversely affect our liquidity. Paying higher deposit rates to attract, retain or replace those deposits could have a negative effect on our interest margin and operating results. A failure to maintain adequate liquidity could have a material adverse effect on our business, financial condition and results of operation.

Previous wording

We cannot be certain as to our ability to manage increased levels of assets and liabilities without increased expenses and higher levels of nonperforming assets. We may be required to make additional investments in equipment and personnel to manage higher asset levels and loan balances, which may adversely affect earnings, shareholder returns, and our efficiency ratio. Increases in operating expenses or nonperforming assets may decrease our earnings and the value of the Company’s capital stock.

Previous wording

Our success depends, to a certain extent, upon general business economic and political conditions, local and national, as well as governmental monetary policies. Conditions such as inflation, recession, unemployment, changes in interest rates, money supply and other factors beyond our control may adversely affect our asset quality, deposit levels and loan demand and, therefore our growth and earnings. In addition, there are continuing concerns related to, among other things, the level of U.S. government debt and fiscal actions that may be taken to address that debt, a potential resurgence of economic and political tensions with or between other countries may have a destabilizing effect on financial markets and economic activity. Economic pressure on consumers, businesses and overall economic uncertainty may result in changes in spending, borrowing, and saving habits. These economic conditions and other negative developments in the domestic or international credit markets and economies may significantly affect the markets in which we do business. Adverse changes in the economy may also have a negative effect on the ability of our borrowers to make timely repayments of their loans, which would have an adverse impact on our earnings.

Previous wording

Inflation began to rise sharply at the beginning of 2022 and remained at an elevated level through the present time. Small to medium-sized businesses may be impacted more during periods of high inflation as they are not able to leverage economies of scale to mitigate cost pressures compared to larger businesses. Consequently, the ability of our business customers to repay their loans may deteriorate, and in some cases this deterioration may occur quickly, which would adversely impact our results of operations and financial condition. Furthermore, a prolonged period of inflation could cause wages and other costs to the Company to increase, which could adversely affect our results of operations and financial condition.

Previous wording

We are subject to extensive regulation, supervision and examination by the Federal Reserve, our primary federal regulator, the Virginia Bureau of Financial Institutions, our chartering authority and the FDIC, as insurer of our deposits. Such regulation and supervision govern the activities in which we may engage, and are intended primarily for the protection of the insurance fund and the depositors and borrowers of the Bank rather than for holders of our capital stock. Various consumers and compliance laws also affect our operations.
