FOR IMMEDIATE RELEASE

**COASTALSOUTH BANCSHARES, INC. REPORTS EARNINGS FOR FIRST QUARTER 2026**

ATLANTA, GA (April 20, 2026) – CoastalSouth Bancshares, Inc. ("CoastalSouth" or the "Company") (NYSE: COSO), the holding company for Coastal States Bank (the "Bank" or "CSB"), today reported net income of $6.3 million, or $0.51 per diluted share, for the first quarter of 2026, compared to approximately $7.1 million, or $0.58 per diluted share, for the fourth quarter of 2025, and $5.1 million, or $0.47 per diluted share, for the first quarter of 2025.

Additionally, on April 17, 2026 the Board of Directors of CoastalSouth Bancshares, Inc. declared a per share quarterly dividend of $0.05. The dividend will be paid in cash to all shareholders with outstanding shares as of the close of business on May 14, 2026, the record date. The dividend shall be paid on May 28, 2026.

Commenting on the Company's results, President and Chief Executive Officer, Stephen R. Stone stated, "We started strong in 2026 by growing $117.9 million in core deposits<sup>1</sup> during the first quarter. Our core deposit growth has allowed us to reduce alternative funding sources and will provide liquidity for continued loan growth. We were pleased to see core deposit growth across all of our markets. We also produced $166.7 million in loans held for investment in the first quarter and our loan pipeline continued to grow, particularly with the addition of new commercial bankers across the franchise."

**First Quarter 2026 Performance Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net income of $6.3 million or $0.51 per diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Return on average assets ("ROAA") of 1.10%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Return on average equity ("ROAE") of 9.71%; Return on average tangible common equity<sup>1</sup> ("ROATCE") of 9.90%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net interest margin of 3.59%, a decrease of 1 basis point from the fourth quarter of 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total deposits increased $69.5 million, driven by growth of $117.9 million in core deposits<sup>1</sup> and a decrease in brokered certificates of deposits of $48.4 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Loans held for investment ("LHFI") production<sup>2</sup> of $166.7 million during the first quarter of 2026 led to LHFI growth of $9.9 million, up 2.5% annualized from the fourth quarter of 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Book value per share growth of $0.28, or 5.24% annualized, to $21.94 at March 31, 2026; Tangible book value<sup>1</sup>per share growth of $0.27, or 5.15% annualized, to $21.52 at March 31, 2026 from the fourth quarter of 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total shareholders' equity to total assets of 11.20%, compared to 11.25% as of the fourth quarter of 2025; Tangible common equity<sup>1</sup> to tangible assets<sup>1</sup> of 11.01%, compared to 11.06% at December 31, 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net charge-offs to average loans held for investment of 0.01%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nonperforming assets to total assets of 0.77%; adjusted nonperforming assets to total assets<sup>1</sup> of 0.62%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Allowance for credit losses ("ACL") on LHFI to total LHFI of 1.16%; ACL on LHFI to nonperforming loans of 103.54%

**Operating Highlights**

Net interest income totaled $19.7 million for the first quarter of 2026, a decrease of approximately $119 thousand, or 0.6%, from $19.9 million for the fourth quarter of 2025, and an increase of approximately $3.0 million, or 17.8% from the first quarter of 2025. The Company's net interest margin decreased by 1 basis point to 3.59% for the first quarter of 2026, compared to 3.60% for the fourth quarter of 2025, and increased 21 basis points from the first quarter of 2025.

The yield on average interest-earning assets for the first quarter of 2026 decreased to 5.92% from 5.98% for the fourth quarter of 2025. This decrease was primarily related to an overall yield decrease in interest-earning assets, primarily federal funds sold, loans held for sale, and investment securities due to recent interest rate cuts, notwithstanding significant growth in average total earning assets. Compared to the first quarter of 2025, yields on earning assets decreased 13 basis points to 5.92% from 6.05%. The decrease was primarily attributable to the aforementioned interest rate cuts during 2025.

**1**

------

The Company's total cost of funds was 2.55% for the first quarter of 2026, a decrease of 5 basis points and 30 basis points compared with the fourth and first quarters of 2025, respectively. Deposit costs decreased 5 and 26 basis points during the first quarter of 2026 to 2.54%, compared to 2.59% and 2.80% in the fourth and first quarters of 2025, respectively. The cost of interest-bearing deposits decreased 8 basis points during the first quarter of 2026 to 3.01%, compared with 3.09% in the fourth quarter of 2025, reflecting continued repricing of certificates of deposits in the first quarter of 2026.

Noninterest income totaled $2.0 million for the first quarter of 2026, a decrease of $328 thousand, or 14.3%, from the fourth quarter of 2025, primarily attributable to a decrease in gain on sale of government guaranteed loans ("GGL"), net of other categories within noninterest income. Noninterest expense totaled $13.0 million for the first quarter of 2026, an increase of $782 thousand, or 6.4%, from the fourth quarter of 2025. This increase was primarily due to higher salaries and employee benefits, other professional services, and other noninterest expense. The Company continues to focus on organic growth and expansion through banker recruiting across the franchise.

The Company's effective tax rate for the first quarter of 2026 was 23.6%, compared to 18.3% for the fourth quarter of 2025, and 23.4% for the first quarter of 2025. The increase in effective tax rate from the fourth quarter of 2025 was primarily due to a lower recognition of benefits from tax credits in the first quarter of 2026.

**Balance Sheet Trends**

Total assets were $2.35 billion at March 31, 2026, an increase of approximately $42.0 million, or 1.8%, from $2.31 billion at December 31, 2025. Loans held for sale ("LHFS") were $202.6 million at March 31, 2026, an increase of $31.7 million, or 18.5%, from $170.9 million at December 31, 2025. Gross LHFI were $1.63 billion at March 31, 2026, an increase of approximately $9.9 million, or 0.6%, from $1.62 billion at December 31, 2025.

Total deposits were $2.06 billion at March 31, 2026, an increase of $69.5 million, or 3.5%, from $1.99 billion at December 31, 2025. Noninterest-bearing deposits were $311.1 million at March 31, 2026, or 15.1% of total deposits, compared to $312.3 million, or 15.7% of total deposits, at December 31, 2025. Brokered certificates of deposit, a component of time deposits, were $258.6 million at March 31, 2026, as compared to $307.0 million at December 31, 2025, a decrease of $48.4 million, or 15.8%.

**Credit Quality**

During the first quarter of 2026, the Company recorded a provision for credit losses of $382 thousand, compared to $1.2 million and $629 thousand during the fourth and first quarters of 2025, respectively. The provision expense recorded during the first quarter of 2026 was due to loan production and mix and economic factors, offset with other changes in loss rates. The Company's annualized net charge-offs to average LHFI ratio was 0.01% for the first quarter of 2026 as compared to 0.00% and 0.00% during the fourth and first quarters of 2025, respectively.

Nonperforming assets totaled $18.2 million, or 0.77% of total assets, at March 31, 2026 compared to $18.3 million, or 0.79% of total assets at December 31, 2025. The $123 thousand decrease in nonperforming assets at March 31, 2026 from December 31, 2025 was primarily due to payments on nonaccrual assets, offset with additions to nonaccrual assets. Adjusted nonperforming assets<sup>3</sup>, which excludes the guaranteed portions of nonaccrual loans, was $14.5 million, or 0.62% of total assets, at March 31, 2026 compared to $14.2 million, or 0.62% of total assets, at December 31, 2025.

*Statements in this press release regarding future events and our expectations and beliefs about our future financial performance and financial condition, as well as trends in our business and markets, constitute "forward-looking statements" within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are not historical in nature and may be identified by references to a future period or periods by the use of the words "believe," "expect," "anticipate," "intend," "plan," "estimate," "project," "outlook," or words of similar meaning, or future or conditional verbs such as "will," "would," "should," "could," or "may." The forward-looking statements in this press release should not be relied on because they are based on current information and on assumptions that we make about future events and circumstances that are subject to a number of known and unknown risks and uncertainties that are often difficult to predict and beyond our control. As a result of those risks and uncertainties, and other factors, our actual financial results in the future could differ, possibly materially, from those expressed in or implied by the forward-looking statements contained in this press release and could cause us to make changes to our future plans.*

*Factors that might cause such differences include, but are not limited to: the impact of current and future economic conditions, particularly those affecting the financial services industry, including the effects of declines in the real estate market, high unemployment rates, inflationary pressures, elevated interest rates and slowdowns in economic growth, as well as the financial stress on borrowers as a result of the foregoing; potential impacts of any adverse developments in the banking industry, including any impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; changes in the interest rate environment, including changes to the federal funds rate; changes in prices, values and sales volumes of residential and commercial real estate; competition in our markets that may result in increased funding costs or reduced earning assets yields, thus reducing margins and net interest income; interest rate fluctuations, which could have an adverse effect on the Company's profitability; a breach in security of our information systems, including the occurrence of a cyber-attack incidents or a deficiencies in cyber security; risks related to potential acquisitions; government actions or inactions, including a prolonged shutdown of the federal government, tariffs, or trade wars (including reduced consumer spending, lower economic growth or recession, reduced demand for U.S. exports, disruptions to supply chains, and decreased demand for other banking products and services), legislation or regulatory changes which could adversely affect the ability of the consolidated Company to conduct business combinations or new operations; changes in tax laws; significant turbulence or a disruption in the capital or financial markets and the effect of a fall in stock market prices on our investment securities; the effects of war or other conflicts, domestic civil unrest and tyranny, and changes in the overall geopolitical landscape; and adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of the Company's participation in and execution of government programs. Therefore, the Company can give no assurance that the results contemplated in the forward-looking statements will be realized.*

*Additional information regarding these and other risks and uncertainties to which our business and future financial performance are subject is contained in the section titled "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors" in the Company's 2025 Annual Report on Form 10-K under the Securities Act of 1933, as amended, filed with the Securities and Exchange Commission (the "SEC") on March 12, 2026, and in other documents that we file with the SEC from time to time, which are available on the SEC's website, http://www.sec.gov.*

*In addition, our actual financial results in the future may differ from those currently expected due to additional risks and uncertainties of which we are not currently aware or which we do not currently view as, but in the future may become, material to our business or operating results. Due to these and other possible uncertainties and risks, readers are cautioned not to place undue reliance on the forward-looking statements contained in this press release or to make predictions based solely on historical financial performance.*

*Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. All forward-looking statements, express or implied, included in this press release are qualified in their entirety by this cautionary statement.*

**Non-GAAP Financial Measures**

The measures entitled return on average tangible common shareholders' equity, tangible book value per common share, tangible common equity, tangible assets, adjusted nonperforming assets to total assets, adjusted nonperforming assets, pre-tax, pre-provision net revenue ("PPNR"), tangible common equity to tangible assets and core deposits are not measures recognized under accounting principles generally accepted in the United States of America ("GAAP") and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are return on average shareholders' equity, book value per share, total shareholders' equity, total assets, total nonperforming assets to total assets, total nonperforming assets, net income, total common equity to total assets, and total deposits, respectively.

Management believes that these non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view the Company's performance using the same tools that management uses to evaluate the Company's past performance and prospects for future performance. While management believes that these non-GAAP financial measures are useful in evaluating our performance, this information should be considered as supplemental and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures should be considered as additional views of the way the Company's financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies.

Disclosures Forward Looking Statements Statements in this Investor Presentation regarding future events and our expectations and beliefs about our future financial performance and financial condition, as well as trends in our business and markets, constitute "forward-looking statements" within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are not historical in nature and may be identified by references to a future period or periods by the use of the words "believe," "expect," "anticipate," "intend," "plan," "estimate," "project," "outlook," or words of similar meaning, or future or conditional verbs such as "will," "would," "should," "could," or "may." The forward-looking statements in this Investor Presentation should not be relied on because they are based on current information and on assumptions that we make about future events and circumstances that are subject to a number of known and unknown risks and uncertainties that are often difficult to predict and beyond our control. As a result of those risks and uncertainties, and other factors, our actual financial results in the future could differ, possibly materially, from those expressed in or implied by the forward-looking statements contained in this Investor Presentation and could cause us to make changes to our future plans. Factors that might cause such differences include, but are not limited to: the impact of current and future economic conditions, particularly those affecting the financial services industry, including the effects of declines in the real estate market, high unemployment rates, inflationary pressures, elevated interest rates and slowdowns in economic growth, as well as the financial stress on borrowers as a result of the foregoing; potential impacts of any adverse developments in the banking industry, including any impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; changes in the interest rate environment, including changes to the federal funds rate; changes in prices, values and sales volumes of residential and commercial real estate; competition in our markets that may result in increased funding costs or reduced earning assets yields, thus reducing margins and net interest income; interest rate fluctuations, which could have an adverse effect on the Company's profitability; a breach in security of our information systems, including the occurrence of a cyber-attack incidents or deficiencies in cyber security; risks related to potential acquisitions; government actions or inactions, including a prolonged shutdown of the federal government, tariffs, or trade wars (including reduced consumer spending, lower economic growth or recession, reduced demand for U.S. exports, disruptions to supply chains, and decreased demand for other banking products and services), legislation or regulatory changes which could adversely affect the ability of the consolidated Company to conduct business combinations or new operations; changes in tax laws; significant turbulence or a disruption in the capital or financial markets and the effect of a fall in stock market prices on our investment securities; the effects of war or other conflicts, domestic civil unrest and tyranny, and changes in the overall geopolitical landscape; and adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of the Company's participation in and execution of government programs. Therefore, the Company can give no assurance that the results contemplated in the forward-looking statements will be realized. Additional information regarding these and other risks and uncertainties to which our business and future financial performance are subject is contained in the sections titled "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors" in the Company's 2025 Annual Report on Form 10-K under the Securities Act of 1933, as amended, filed with the Securities and Exchange Commission (the "SEC") on March 12, 2026 and in other documents that we file with the SEC from time to time, which are available on the SEC's website, http://www.sec.gov. In addition, our actual financial results in the future may differ from those currently expected due to additional risks and uncertainties of which we are not currently aware or which we do not currently view as, but in the future may become, material to our business or operating results. Due to these and other possible uncertainties and risks, readers are cautioned not to place undue reliance on the forward-looking statements contained in this Investor Presentation or to make predictions based solely on historical financial performance. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. All forward-looking statements, express or implied, included in this Investor Presentation are qualified in their entirety by this cautionary statement.

Disclosures Non-GAAP Financial Measures In addition to results presented in accordance with U.S. generally accepted accounting principles ("GAAP"), this Investor Presentation contains certain non-GAAP financial measures. The Company believes that providing certain non-GAAP financial measures provides investors with information useful in understanding our financial performance, performance trends and financial position. Our management uses these measures for internal planning and forecasting purposes and we believe that our presentation and discussion, together with the accompanying reconciliations, allows investors, security analysts and other interested parties to view our performance and the factors and trends affecting our business in a manner similar to management. These non-GAAP measures should not be considered a substitute for GAAP measures and we strongly encourage investors to review our consolidated financial statements in their entirety and not to rely on any single financial measure to evaluate the Company. Non-GAAP financial measures have inherent limitations, are not uniformly applied and are not audited. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names. The measures entitled return on average tangible common shareholders' equity, tangible book value per common share, tangible common equity, tangible assets, adjusted nonperforming assets to total assets, adjusted nonperforming assets, pre-tax, pre-provision net revenue ("PPNR"), tangible common equity to tangible assets and core deposits are not measures recognized under accounting principles generally accepted in the United States of America ("GAAP") and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are return on average shareholders' equity, book value per share, total shareholders' equity, total assets, total nonperforming assets to total assets, total nonperforming assets, net income, total common equity to total assets, and total deposits, respectively. The delivery of this Investor Presentation will not, under any circumstances, create an implication that there has been no change in the affairs of the Company since the date of this Investor Presentation. The Company is not making any implied or express representation or warranty as to the accuracy or completeness of the information summarized herein or made available in connection with any further investigation of the Company. The Company expressly disclaims any and all liability which may be based on such information, errors therein or omission therefrom.

Noninterest Expense Salaries and benefits increased during the first quarter due to payroll tax and 401k contribution increases associated with incentive payouts and restart of payroll taxes for those who had phased out in 2025. The Company continues to focus on organic growth and expansion through banker recruitment across the franchise. Professional fees increased during the quarter due to recruiting costs, increased legal expenses, primarily due to review of SEC deliverables for the Company's first public annual reporting cycle and proxy and other corporate matters, and loan workout costs.
