Archie Brown, President and CEO, commented on third quarter results, "Third quarter financial results reflect our ongoing commitment to industry leading performance. Adjusted(1) earnings per share were $0.67, which resulted in an adjusted(1) return on assets of 1.42% and an adjusted(1) return on tangible common equity of 19.77%. We are particularly pleased with our 4.08% net interest margin. With only a 2 bp decline from the second quarter, the margin has proven to be more durable than expected due to high asset yields from Agile, investment portfolio restructuring and moderating funding costs. Average deposit balances grew 4.9% on an annualized basis, as declines in our low cost products moderated. Consistent with our expectations, loan growth slowed during the third quarter as softer pipelines in the second quarter led to fewer fundings in the current period. Loan growth was also impacted by higher payoffs in our commercial banking and investment commercial real estate portfolios. Loan pipelines strengthened during the third quarter, and we expect higher growth rates as we close out the year." Mr. Brown continued, "Third quarter noninterest income was $45.7 million, or $58.8 million on an adjusted(1) basis, with strong earnings from foreign exchange, wealth management and the leasing business. There were several large non-recurring items that impacted noninterest income, including $17.5 million of losses on securities, which included a $9.7 million impairment charge on two bonds secured by skilled nursing homes. While third quarter noninterest income was noisy, noninterest expenses were relatively flat compared to the prior quarter. We remain diligent in managing our expenses, and our workforce efficiency initiative has resulted in the elimination of 120 positions to date, with additional savings expected into 2025." Mr. Brown commented on asset quality and capital, "Asset quality was stable for the quarter and our ACL increased to 1.37% of total loans. Additionally, third quarter net charge-offs were 25 bps on an annualized basis and nonperforming assets as a percent of assets increased 1 bp to 36 bps. We are optimistic about asset quality and are confident in our ability to manage the portfolio through the expected interest rate reductions and economic uncertainty in the near-term. With regard to capital, strong earnings and the decline in interest rates led to significant improvement in tangible book value per share and tangible common equity. Tangible book value per share increased 10% from the linked quarter and over 30% from the same quarter last year to $14.26, while tangible common equity increased 75 basis points from June 30 to 7.98% as of the end of September." Mr. Brown concluded, "We are very proud of our financial results in the first nine months of 2024. Overall, the economy remains healthy, and the general easing of interest rates should extend economic growth in the coming periods. We believe we are in a strong position to finish the year on a high note and head into 2025 with continued momentum."
