ATLANTA--(BUSINESS WIRE)-- 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 $8.8 million, or $0.71 per diluted share, for the third quarter of 2026, compared to approximately $7.3 million, or $0.59 per diluted share, for the second quarter of 2026, and $6.7 million, or $0.54 per diluted share, for the third quarter of 2025. For the nine months ended September 30, 2026, the Company reported net income of $22.4 million, or $1.81 per diluted share, compared with $17.8 million, or $1.58 per diluted share, for the same period in 2025. Additionally, on October 19, 2026, the Board of Directors of CoastalSouth Bancshares, Inc. declared a per share quarterly dividend of $0.06. The dividend will be paid to shareholders of record as of the close of business on November 10, 2026, the record date. The dividend shall be paid on November 24, 2026. Commenting on the Company’s third quarter performance, President and Chief Executive Officer Stephen R. Stone stated, "We delivered record earnings of $0.71 per share in the third quarter, driven by strong loan production and robust gain-on-sale revenue from our government-guaranteed lending business. We saw outstanding loan production 2 of $248.2 million during the third quarter, driving an $81.6 million increase in loans held-for-investment, or 19.0% annualized. The majority of production in the third quarter continued to come from the community bank, although our specialty lines of business also had a strong production quarter. As we head into the fourth quarter, we remain focused on building deep client relationships, maintaining disciplined underwriting, and investing in talented bankers across our footprint." Third Quarter 2026 Performance Highlights: Net income of $8.8 million or $0.71 per diluted share Return on average assets ("ROAA") of 1.45% Return on average equity ("ROAE") of 12.88%; Return on average tangible common equity 1 ("ROATCE") of 13.12% Net interest margin of 3.70%, an increase of 4 basis points from the second quarter of 2026 Total deposits increased $53.1 million, although core deposits 1 were down quarter over quarter approximately $20.0 million which is primarily attributable to seasonal outflows associated with our property management clients Loans held-for-investment ("LHFI") production 2 of $248.2 million during the third quarter of 2026 led to LHFI growth of $81.6 million, up 19.0% annualized from the second quarter of 2026 Accumulated other comprehensive loss ("AOCL") increased by $8.3 million from prior quarter due to increased unrealized losses in our available-for-sale securities portfolio Book value per share decreased $0.15, or 2.65% annualized, to $22.32 at September 30, 2026; Tangible book value 1 per common share decreased $0.16, or 2.88% annualized, to $21.90 at September 30, 2026 from the second quarter of 2026 Share repurchase program launched May 1, 2026; 285,715 shares repurchased during the third quarter of 2026 with a weighted-average price of $27.10 Total shareholders' equity to total assets of 10.81%, compared to 11.14% as of the second quarter of 2026; Tangible common equity 1 to tangible assets 1 of 10.63%, compared to 10.96% as of June 30, 2026 Net charge-offs to average loans held for investment of 0.01% Nonperforming assets to total assets of 0.62%; adjusted nonperforming assets to total assets 1 of 0.45% Allowance for credit losses ("ACL") on LHFI to total LHFI of 1.10%; total ACL on LHFI to nonperforming loans of 130.13% ______________________________ 1 Considered non-GAAP financial measure - See "Non-GAAP Financial Measures" and reconciliation of GAAP to non-GAAP financial measures in tables 10A - 10E. 2 The Company defines production as original loan commitment amount, which includes both funded and unfunded balances at the time of origination. As of September 30, 2026, these loans had funded balances of $148.9 million and unfunded commitments of $74.1 million. Operating Highlights Net interest income totaled $21.5 million for the third quarter of 2026, an increase of $862 thousand, or 4.2%, from $20.7 million for the second quarter of 2026, and an increase of $2.3 million, or 12.2% from the third quarter of 2025. The Company’s net interest margin increased by 4 basis points to 3.70% for the third quarter of 2026, compared to 3.66% for the second quarter of 2026, and increased 12 basis points from the third quarter of 2025. The yield on average interest-earning assets for the third quarter of 2026 increased to 5.99% from 5.94% for the second quarter of 2026. This increase was primarily related to an overall yield increase in average interest-earning assets across the board, principally investment securities, LHFI and loans held-for-sale ("LHFS"). Compared to the third quarter of 2025, yields on earning assets decreased 15 basis points to 5.99% from 6.14%. The decrease was primarily attributable to interest rate cuts during 2025, notwithstanding $186.0 million of growth in average total earning assets. The Company’s total cost of funds was 2.51% for the third quarter of 2026, an increase of 1 basis point compared to the second quarter of 2026, and a decrease of 28 basis points compared to the third quarter of 2025. Deposit costs were 2.48% for the third quarter of 2026, similar to 2.48% for the second quarter of 2026, and compared to 2.72% for the third quarter of 2025, a decrease of 24 basis points from the third quarter of 2025. The cost of interest-bearing deposits increased 2 basis points during the third quarter of 2026 to 2.97%, compared with 2.95% in the second quarter of 2026, reflecting continued repricing of our interest-bearing deposits to align with competitive rate pressure associated with the markets expectation of the Federal Reserve hiking rates during the third quarter of 2026. Noninterest income totaled $3.3 million for the third quarter of 2026, an increase of $1.1 million, or 51.2%, from the second quarter of 2026, primarily attributable to an increase in gain on sale of government guaranteed loans by $1.3 million; offset by a net decrease in other categories within noninterest income. Noninterest expense totaled $13.7 million for the third quarter of 2026, an increase of $336 thousand, or 2.5%, from the second quarter of 2026. This increase was primarily due to higher salaries and employee benefits of $299 thousand, coupled with a net increase in other noninterest expense categories. The Company continues to focus on organic growth and expansion through banker recruiting across the franchise. The Company’s effective tax rate for the third quarter of 2026 was 24.2%, compared to 17.0% for the second quarter of 2026, and 23.2% for the third quarter of 2025. The increase in effective tax rate from the second quarter of 2026 was primarily due to a reduction in the deferred tax asset related to state taxes during the third quarter of 2026 of approximately $641 thousand. Excluding discrete items related to this write-down and stock based compensation activity, the Company's effective tax rate at the end of the third quarter of 2026 was 20.05%. Balance Sheet Trends Total assets were $2.42 billion at September 30, 2026, an increase of approximately $117.2 million, or 5.1%, from $2.31 billion at December 31, 2025. LHFS were $142.4 million at September 30, 2026, a decrease of $28.5 million, or 16.7%, from $170.9 million at December 31, 2025. Gross LHFI were $1.79 billion at September 30, 2026, an increase of approximately $169.6 million, or 10.5%, from $1.62 billion at December 31, 2025. Total deposits were $2.10 billion at September 30, 2026, an increase of $113.1 million, or 5.7%, from $1.99 billion at December 31, 2025. Noninterest-bearing deposits were $340.4 million at September 30, 2026, or 16.2% 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 $257.0 million at September 30, 2026, as compared to $307.0 million at December 31, 2025, a decrease of $50.0 million, or 16.3%. Credit Quality During the third quarter of 2026, the Company recorded a recovery for credit losses of $429 thousand, compared to a provision for credit losses of $658 thousand and $653 thousand during the second quarter of 2026 and the third quarter of 2025, respectively. The recovery for credit losses recorded during the third quarter of 2026 was due to changes in the economic forecast and loan mix, offset by new loan production. The Company's annualized net charge-offs to average LHFI ratio was 0.01% for the third quarter of 2026 as compared to 0.01% and 0.03% during the second quarter of 2026 and the third quarter of 2025, respectively. Nonperforming assets totaled $15.1 million, or 0.62% of total assets, at September 30, 2026 compared to $18.3 million, or 0.79% of total assets at December 31, 2025. The decrease in nonperforming loans was primarily due to a $4.2 million paydown of one nonaccrual senior housing loan, offset by modest additions to nonaccrual loans. Adjusted nonperforming assets 3 , which excludes the guaranteed portions of nonaccrual loans, was $10.9 million, or 0.45% of total assets, at September 30, 2026 compared to $14.2 million, or 0.62% of total assets, at December 31, 2025. ______________________________ 3 Considered non-GAAP financial measure - See "Non-GAAP Financial Measures" and reconciliation of GAAP to non-GAAP financial measures in tables 10A - 10E.

Non-GAAP Financial Measures The measures entitled return on average tangible common 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.
