(January 27, 2026 / GLOBE NEWSWIRE) — Central Bancompany, Inc. (Nasdaq: CBC) (“Central Bancompany”, “the Company”, or “CBC”), the bank holding company for The Central Trust Bank (the “Bank”), today announced preliminary financial results for the fourth quarter and full year 2025. John “JR” Ross, President and Chief Executive Officer of Central Bancompany, commented "We are pleased to announce record profitability in 2025, as our employees continued to deliver for our customers, our communities and our shareholders. Our retail net promoter score rose to 74 and our wealth net promoter score to 83, reflecting the quality of the service we deliver to our customers. Our employees spent over 28 thousand hours volunteering in the communities we serve. The drivers of our financial performance were broad-based, reflecting efforts across our organizations and in all our markets. I want to thank our teammates for their outstanding efforts in delivering these outcomes.” “We have a lot to accomplish in 2026, including delivering on the expectations set by our shareholders on the heels of a successful 2025,” Ross continued. “As we look to 2026, we remain focused on prudently growing the business, continuing our technology build out, and thoughtfully deploying our excess capital. We feel ready to meet those challenges and will continue to dedicate ourselves to our customers, communities and shareholders.” Net Interest Income and Net Interest Margin 1 The Company reported net interest income of $206.5 million in the fourth quarter of 2025, reflecting a GAAP net interest margin of 4.38% (4.41% on an FTE basis 1, 2). Earning assets averaged $18.7 billion during the quarter. The increase of $7.6 million in net interest income from the third quarter 2025 reflected the investment of $403.1 million of net IPO proceeds and a 2 basis point increase in net interest margin from last quarter. Average earning assets for the quarter totaled $18.7 billion, an increase of $0.6 billion, or 3.4% from the prior quarter’s average earning assets, driven by $0.5 billion of higher short-term earning assets primarily resulting from the net IPO proceeds. Earning assets ended the quarter at $19.7 billion, $1.0 billion higher than the average during the quarter as we saw seasonally driven deposit growth the end of the year and loan growth across several loan categories. The increase in FTE net interest margin to 4.41% from 4.39% reflects an FTE loan yield of 6.27% this quarter, relatively flat from the prior quarter despite a full quarter of the September rate cut and two further rate cuts during the quarter. The cost of deposits fell 5 basis points to 1.14% for the fourth quarter 2025. Exhibit 99.1 1- 1 All references to net interest income and net interest margin are presented on a fully-tax equivalent basis unless otherwise noted. 2 This is a non-GAAP financial measure management believes is helpful to understanding trends in our business that may not be fully apparent based only on the most comparable GAAP financial measure. Further information on this financial measure and a reconciliation to the most comparable GAAP financial measure is provided at the end of this release.

For the full year of 2025, net interest income was $789.7 million, an increase of $102.3 million from the prior year. Earning assets averaged $18.4 billion in 2025, an increase of $0.5 billion from 2024, driven by higher investment securities. Average deposits grew $0.2 billion, or 1.2%, while average loans declined slightly by $0.1 billion, or 1.1%. Full year net interest margin was 4.30% for 2025, up 46 basis points from the 3.84% net interest margin in 2024. Total loans held for investment were $11.4 billion at December 31, 2025, an increase of $0.1 billion or 1.0% from September 30, 2025. Loan growth in the quarter was driven by increases in construction and development, commercial, financial & agricultural, residential mortgage and home equity lines of credit partially offset by declines in commercial real estate and other consumer loans. Total deposits were $15.9 billion at December 31, 2025, an increase of approximately $1.1 billion or 7.3% from September 30, 2025. The increase from the prior quarter was largely due to seasonality, as our public funds customers typically see significant inflows at the end of the year. Average non-public fund deposits increased by 1.7%. On a year-over-year basis, total deposits were up approximately $0.9 billion, or 5.9%. Noninterest-bearing demand deposits increased by $0.4 billion and savings and interest-bearing demand deposits grew by $0.6 billion, $0.3 billion of which are increases in public funds. Time deposits decreased slightly. Seven of our eleven primary markets grew deposits in 2025. Provision for credit losses The provision for credit losses was $3.0 million for the fourth quarter 2025, relatively flat to the prior quarter. The allowance for credit losses at the end of the quarter was $149.7 million, which was 1.31% of loans held for investment. The allowance for credit losses was $149.5 million (1.32% of loans held for investment) at the end of the prior quarter. For the full year 2025, the provision for credit losses was $9.3 million, down $5.3 million from the prior year. The provision for 2025 included a $5.0 million release of allowance associated with the decision in Q2 of 2025 to sell the consumer leasing portfolio. Noninterest income Noninterest income was $65.8 million for the fourth quarter of 2025, higher by $8.7 million from the prior quarter. The prior quarter included $6.9 million of losses from the sales of investment securities, as we accelerated the reinvestment of nearer-term maturities in the securities portfolio to reduce our asset sensitivity to rates in the 2 to 5-year section of the yield curve. Excluding these losses in the prior quarter, current quarter noninterest income was $1.8 million higher than the prior quarter’s adjusted noninterest income2. The increase was driven by our Wealth Management segment where both brokerage services and fees for fiduciary services increased by $0.4 million and $1.2 million, respectively. Fees for fiduciary services benefited from strong investment inflows and investment performance. Assets under advice grew approximately 3.5% from the prior quarter to $16.0 billion as of December 31, 2025. The fee income ratio for the quarter was 24.2%, relatively flat to the adjusted fee income ratio 2 in the prior quarter, despite the higher levels of net interest income, reflecting that fee income continued to keep pace with growth in net interest income. For the year, noninterest income was $231.7 million, up $21.3 million from the prior year. Net losses from the sales of investment securities in both years and the loss from the expected sale of the consumer leasing portfolio in Q2 of 2025 affected comparability between both periods. Adjusting for both items, adjusted noninterest income 2 was $252.1 million in 2025, an increase of $5.1 million from the prior year. The higher level of noninterest income in 2025 reflects an increase in fees for fiduciary services of $6.1 million and an increase of $3.0 million in brokerage services, offset partially by a decline in mortgage banking revenues of $2.5 million and a gain on the sale of equipment totaling $3.6 million, included in the prior year’s other noninterest income which did not recur. The adjusted fee income ratio2 for 2025 was 24.2%, down from the adjusted fee income ratio2 for 2024 of 26.4%. Noninterest expense Noninterest expense for the fourth quarter 2025 was $129.5 million, a $2.6 million increase from the third quarter 2025. Salaries and benefits expense increased $1.5 million from the prior quarter due to higher incentives as a result of year-end performance and other expenses were higher by $1.9 million, spread across a number of categories. Our efficiency ratio (FTE) 2 of 47.0% improved from the 47.7% efficiency ratio (FTE) of the prior quarter. For the full year 2025, noninterest expense was $505.5 million, an increase of $16.1 million, or 3.3%. Higher salaries and benefits of $17.0 million drove this change. A decrease in legal and professional fees of $3.9 million partially offset this increase, due to anticipated progression in our core modernization project. Our efficiency ratio (FTE)2 of 47.9% for 2025 improved from the 51.7% efficiency ratio (FTE) of the prior year. 2-

Provision for income taxes The fourth quarter 2025 provision for income taxes was $32.1 million, $3.6 million higher than the prior quarter. The effective tax rate for the fourth quarter 2025 was 23.0% compared to 22.7% in the prior quarter. The current quarter reflected a 40 bps impact of certain costs that are no longer deductible as a result of being a public company. For the full year 2025, the provision for income taxes was $115.7 million, up $27.8 million from the prior year, driven by higher levels of pre-tax income. The effective tax rate for the current year was 22.8%, which was up from 22.3% in the prior year due primarily to a reduction year over year in the amount of state tax credits received from tax credit partnerships. Asset quality Asset quality remained strong. Nonperforming loans at December 31, 2025 were $46.0 million, or 40 bps of loans held for investment, down from 45 bps at the end of the prior quarter. Net charge-offs were $2.8 million for the quarter, 10 bps (annualized) of average total loans. Our allowance for credit losses of $149.7 million represented 131 bps of loans held for investment. Compared to the prior year end, nonperforming loans at December 31, 2025 were up $6.5 million and the allowance was down 2 basis points as a percent of loans held for investment from the prior year. Delinquent loans at December 31, 2025 were $36.4 million, or 32 bps of loans held for investment, as compared to 21 bps at the end of the prior quarter and 55 bps at the end of the prior year. Delinquency levels at December 31, 2025 remain aligned with historical, pre-COVID seasonal patterns. Delinquency increased on a linked quarter basis at the end of the fourth quarter, driven by increases in consumer installment and consumer credit card delinquency. Capital Capital levels at December 31, 2025 remained very strong. Our CET1 ratio was 28.1% and represented $1.8 billion of excess capital when compared to our long-term CET1 target of 13.5%. The Bank’s CET1 ratio was 12.9% at December 31, 2025. The difference in the consolidated capital ratio and the capital ratio at the Bank represents earnings that have already been upstreamed to the holding company. Compared to the prior year end, our CET1 increased 443 bps, the result of the net IPO proceeds and earnings retention. Our book value per share at December 31, 2025 was $15.69 per share, whereas our tangible book value was $14.24 per share.
