Chain Bridge Bancorp, Inc. (NYSE: CBNA) (the “Company”), the holding company for Chain Bridge Bank, N.A. (the “Bank”), today announced financial results for the third quarter of 2025 and the nine months ended September 30, 2025.

Peter G. Fitzgerald, Chairman of Chain Bridge Bancorp, Inc., commented:

•Consolidated Net Income: $4.7 million

•Earnings Per Share: $0.72 per basic and diluted common share outstanding

•Return on Average Equity: 11.67% (on an annualized basis)

•Return on Average Assets: 1.27% (on an annualized basis)

•Book Value Per Share: $24.86

•Consolidated Net Income: $14.9 million

•Earnings Per Share: $2.27 per basic and diluted common share outstanding

•Return on Average Equity: 12.93% (on an annualized basis)

•Return on Average Assets: 1.33% (on an annualized basis)

For the quarter ended September 30, 2025, the Company reported net income of $4.7 million, compared to $4.6 million for the quarter ended June 30, 2025 and $7.5 million for the quarter ended September 30, 2024. Earnings per share (“EPS”) was $0.72, compared to $0.70 for the quarter ended June 30, 2025 and $1.64 for the quarter ended September 30, 2024.

The quarter-over-quarter increase in earnings primarily reflected higher net interest income, resulting from growth in interest earned on deposits at the Federal Reserve and taxable securities income. These factors were partially offset by a $220 thousand reduction in the recapture of credit losses and higher noninterest expense, primarily associated with salaries and employee benefits.

Total consolidated deposits were $1.4 billion as of September 30, 2025, compared to $1.3 billion at June 30, 2025. IntraFi Cash Service® (ICS®) One-Way Sell® deposits totaled $146.4 million, up from $121.2 million in the prior quarter.

Net income for the quarter declined by $2.8 million from the third quarter of 2024, primarily due to lower deposit placement services income and a decline in net interest income. The reduction in deposit placement services income reflected a shift of One-Way Sell® deposits onto the balance sheet and lower overall deposit activity compared to the elevated levels observed during the 2024 federal election cycle.

Net income for the nine months ended September 30, 2025 was $14.9 million, compared to $17.2 million for the same period in 2024. The decrease was attributable to a $5.0 million reduction in noninterest income, driven by changes in One-Way Sell® deposit activity and greater use of reciprocal ICS® deposits, and a $2.9 million increase in noninterest expenses principally related to costs associated with operational growth and functioning as a public company. These effects were partially offset by a $4.9 million increase in net interest income, reflecting growth in the investment securities portfolio.

Earnings per share for the first nine months of 2025 was $2.27, compared to $3.77 for the same period in 2024. The decline in EPS resulted from the decrease in net income and the increase in shares outstanding following the Company’s initial public offering (“IPO”) in October 2024, through which it issued 1,992,897 shares of Class A common stock.

As of September 30, 2025, book value per share (“BVPS”) was $24.86, compared to $21.98 at December 31, 2024 and $22.95 at September 30, 2024.

During the first nine months of 2025, stockholders’ equity increased by $18.9 million, primarily reflecting earnings of $14.9 million during the period. The increase also included a $4.0 million reduction in accumulated other comprehensive loss, resulting from an increase in the fair value of the available-for-sale investment securities portfolio, net of tax. The increase in fair value primarily reflected lower U.S. Treasury interest rates at September 30, 2025 compared to December 31, 2024 increasing the market value of fixed-rate securities, as well as the pull-to-par effect as certain securities moved closer to maturity and their prices converged toward their par values.

The year-over-year increase in stockholders’ equity of $58.3 million was driven by $18.6 million in earnings retained during the period, $36.5 million in net proceeds from the Company’s IPO in October 2024 and the related over-allotment exercise in November 2024, and a $3.1 million reduction in accumulated other comprehensive loss attributable to an increase in the fair value of available-for-sale investment securities, net of tax. These additions, which supported the Company’s BVPS, were partially offset by the issuance of 1,992,897 shares of Class A common stock in connection with the IPO and related over-allotment exercise, and resulted in a net increase to BVPS from $22.95 as of September 30, 2024 to $24.86 as of September 30, 2025.

Net interest income for the third quarter of 2025 was $12.3 million, compared to $11.8 million for the second quarter of 2025 and $13.6 million for the third quarter of 2024. The net interest margin was 3.35% in the third quarter of 2025, compared to 3.39% in the second quarter of 2025 and 3.73% in the third quarter of 2024.

The increase in net interest income from the prior quarter primarily reflected higher average balances held in interest-bearing deposits at the Federal Reserve, and higher average balances and yields on taxable securities. These factors were partially offset by a $187 thousand increase in interest expense on deposits. Although net interest income increased from the prior quarter, the larger volume of average interest-earning assets resulted in an overall decline in net interest margin.

Net interest income and margin were lower in the third quarter of 2025 than in the third quarter of 2024. Lower average balances held in interest-bearing deposits at other banks, particularly at the Federal Reserve, together with declining short-term rates, drove the decline in net interest income and net interest margin compared to the third quarter of 2024. These balances were elevated in the prior year as a result of inflows from political organization deposit accounts leading up to the 2024 federal elections. The subsequent outflows of those deposits during the fourth quarter of 2024 and of post-election fundraising deposits in the second quarter of 2025 resulted in a decline in balances held at the Federal Reserve. In addition, interest on deposits was $1.2 million during the third quarter of 2025, an increase of $345 thousand compared to the third quarter of 2024 despite a decline in the cost of interest-bearing deposits. Average interest-bearing deposits increased in the third quarter of 2025, reflecting a greater proportion of interest-bearing balances, as the Company’s post-IPO capital position provided additional balance sheet capacity to hold reciprocal ICS® deposits that had previously been placed off-balance sheet as One-Way Sell® deposits. Higher average balances and yields in the taxable investment securities portfolio increased interest income from that segment, partially offsetting the decline in income from interest-bearing deposits in other banks and the increase in interest expense on deposits.

For the nine months ended September 30, 2025, the Company reported higher net interest income but a lower net interest margin compared to the same period in 2024. Net interest income was $37.9 million with a net interest margin of 3.44%, compared to $33.0 million and 3.47%, respectively, for the nine months ended September 30, 2024. The increase in interest income was primarily driven by higher average balances in, and yields on, taxable investment securities. Although the average balance of interest-bearing deposits at the Federal Reserve was higher during the nine months ended September 30, 2025 than in the same period in 2024, lower yields on those balances drove a $1.2 million net reduction in this segment’s interest income. Overall, growth in interest-earning assets outpaced the increase in net interest income, resulting in a decline in the net interest margin from 3.47% to 3.44%.

Noninterest income for the third quarter of 2025 was $847 thousand, compared to $828 thousand in the second quarter of 2025 and $3.1 million for the third quarter of 2024.

Compared with the third quarter of 2024, noninterest income declined due to lower deposit placement services income from ICS® One-Way Sell® deposits placed through the ICS® network. In the prior year period, a larger portion of political organization deposits was placed off-balance sheet as One-Way Sell® deposits. Following the Company’s IPO, higher capital levels provided additional balance sheet capacity, allowing a greater proportion of deposits to be retained as reciprocal ICS® deposits. Reciprocal ICS® deposits that remain on our balance sheet support our net interest margin; however, unlike off-balance sheet One-Way Sell® deposits, they do not generate income from deposit placement service fees.

For the nine months ended September 30, 2025, noninterest income was $2.4 million, compared to $7.4 million during the same period in 2024, reflecting these same factors and the typical decrease in political deposit activity during a non-election year.

Total noninterest expense for the third quarter of 2025 was $7.3 million, compared to $7.2 million in the second quarter of 2025 and $7.4 million in the third quarter of 2024.

For the nine months ended September 30, 2025, noninterest expense was $22.1 million, compared to $19.2 million for the same period in 2024. The year-to-date increase reflected a broader expense structure associated with the Company’s growth, increased operational complexity, and expanded operations as a public company. The largest contributor was a $1.5 million increase in salaries and employee benefits compared to the prior-year period, driven by a larger workforce to support the Company’s general growth and public company operations, as well as periodic salary adjustments.

As of September 30, 2025:

•Total assets were $1.5 billion, compared to $1.4 billion as of December 31, 2024 and $1.6 billion as of September 30, 2024.

•Total deposits were $1.4 billion, compared to $1.2 billion as of December 31, 2024, and $1.4 billion as of September 30, 2024.

•Total ICS® One-Way Sell® deposits were $146.4 million, compared to $63.3 million as of December 31, 2024, and $432.3 million as of September 30, 2024.

•Interest-bearing reserves held at the Federal Reserve were $388.2 million, compared to $406.7 million as of December 31, 2024 and $627.0 million as of September 30, 2024.

•Total investment securities were $831.5 million, compared to $658.8 million as of December 31, 2024 and $597.1 million as of September 30, 2024.

•Total loans held for investment, net of the allowance for credit losses, were $280.0 million, compared to $308.8 million as of December 31, 2024, and $295.8 million as of September 30, 2024.

•The loan-to-deposit ratio was 20.82% compared to 25.09% as of December 31, 2024, and 20.92% as of September 30, 2024.

•The ratio of non-performing assets to total assets remained at 0.00%, unchanged from December 31, 2024 and September 30, 2024.

As of September 30, 2025, the Company’s liquidity ratio was 89.54%, compared to 88.21% at June 30, 2025 and 85.31% at September 30, 2024. The liquidity ratio is calculated as the sum of cash and cash equivalents plus unpledged investment-grade securities, divided by total liabilities. Cash, cash equivalents, and unpledged securities totaled $1.2 billion at September 30, 2025, $1.1 billion at June 30, 2025, and $1.2 billion at September 30, 2024.

As of September 30, 2025, the Company’s tangible common equity to tangible total assets ratio was 10.63%, compared to 10.86% at June 30, 2025 and 6.74% at September 30, 2024. This ratio, which is calculated in accordance with GAAP, represents common equity divided by total assets. The Company did not have any goodwill or other intangible assets for the periods presented.

The quarter-over-quarter change in this ratio reflected higher total equity from retained earnings and a reduction in accumulated other comprehensive loss, offset by an increase in assets. The year-over-year increase reflected retained earnings and the capital raised through the Company’s IPO and subsequent partial exercise of the underwriters’ over-allotment option.

As of September 30, 2025, the Company reported a Tier 1 leverage ratio of 11.34%, a Tier 1 risk-based capital ratio of 44.43%, and a total risk-based capital ratio of 45.56%. As of June 30, 2025, the Company reported a Tier 1 leverage ratio of 11.45%, a Tier 1 risk-based capital ratio of 43.48% and a total risk-based capital ratio of 44.64%. As of September 30, 2024, the Company’s Tier 1 leverage ratio stood at 7.59%, the Tier 1 risk-based capital ratio at 28.17% and the total risk-based capital ratio at 29.29%. The year-over-year increase in all capital ratios reflect retained earnings growth and the capital raised through the IPO and related over-allotment exercise.

As of September 30, 2025, the Trust & Wealth Department oversaw total assets under administration (“AUA”) of $552.4 million, which included $196.1 million in assets under management (“AUM”) and $356.3 million in assets under custody (“AUC”). This compares to $445.4 million in AUA as of June 30, 2025, which included $158.1 million in AUM and $287.3 million in AUC. As of September 30, 2024, AUA stood at $384.0 million, including $111.2 million in AUM and $272.8 million in AUC. The increases in AUA from both the prior quarter and prior year primarily reflect account growth, asset inflows, and the impact of market performance. AUA are not captured on the consolidated balance sheets.

Trust and wealth management income, which has increased commensurately with changes in AUA, was $355 thousand in the third quarter of 2025, compared to $305 thousand in the second quarter of 2025 and $243 thousand in the third quarter of 2024.

As of September 30, 2025, total consolidated deposits were $1.4 billion, compared to $1.3 billion as of June 30, 2025 and $1.6 billion as of March 31, 2025.

Historically, deposits from political organizations have typically increased in the periods leading up to federal elections, declined in the quarters around federal elections, and tended to rebuild gradually in the quarters following federal elections. Deposit balances during early 2025 were affected by sizable political organization account movements, beginning with first-quarter inflows that were more concentrated and differently timed than in prior election cycles. These inflows were the result of a post-election surge in deposits following the November 2024 federal elections. This was followed by a significant outflow from certain political organization accounts early in the second quarter, which began to rebuild by June 30. In the third quarter, political deposit inflows contributed to a $114.6 million quarter-over-quarter increase in total consolidated deposits.

15 On October 3, 2024, the Company filed an Amended and Restated Certification of Incorporation with the Secretary of State of the State of Delaware, which reclassified and converted each outstanding share of the Company's existing common stock, par value $1.00 per share into 170 shares of Class B Common Stock (the "Reclassification"). Historical share information is presented on an as adjusted basis giving effect to the Reclassification. The number of basic and diluted weighted average shares used in computing earnings per share are the same because there are no potentially dilutive instruments.

16 Derived from audited financial statements.

17 On October 3, 2024, the Company filed an Amended and Restated Certification of Incorporation with the Secretary of State of the State of Delaware, which reclassified and converted each outstanding share of the Company's existing common stock, into 170 shares of Class B Common Stock (the “Reclassification”). The Reclassification also authorized 20,000,000 shares of Class A Common Stock, and 10,000,000 shares of Preferred Stock. Historical share information is presented on an as adjusted basis giving effect to the Reclassification. All shares and balances from previously held common stock are reflected in Class B Common Stock.

18 Share information presented prior to the Reclassification date of October 3, 2024 gives effect to the Reclassification and attributes all earnings to Class B shares because no Class A shares were outstanding prior to the Reclassification. The number of basic and diluted shares are the same because there are no potentially dilutive instruments. Except in regard to voting and conversion rights, the rights of Class A Common Stock and Class B Common Stock are identical, and the classes rank equally and share ratably with regard to all other matters. Each share of Class B Common Stock is convertible at any time into one share of Class A Common Stock.

The following tables show the average outstanding balance of each principal category of our assets, liabilities and stockholders’ equity, together with the average yields on our interest-earning assets and the average costs of our interest-bearing liabilities for the periods indicated. Such yields and costs are calculated by dividing the annualized income or expense by the average daily balances of the corresponding assets or liabilities for the same period.

19 Average balances for securities transferred from AFS to HTM at fair value are shown at carrying value. Average balances for AFS are shown at fair value, and all other HTM bonds are shown at amortized cost.

20 The yield for short term borrowings reflects interest expense incurred during the period. When the amount of interest expense was less than our rounding threshold, it is displayed as $0.
