14 Near-Term Outlook nLoan pipelines are currently in line with 3Q25 and we are expecting loan growth in the low single digits on an annualized basis in 4Q25. nConsistent with 3Q25, we expect net interest income and net interest margin to be relatively stable in 4Q25. nWe expect deposit balances to be up slightly in 4Q25. nWe intend to be opportunistic around debt securities purchases based on interest rates but expect investment balances to be generally stable in 4Q25. nNoninterest income is expected to be flat in 4Q25. nExcluding acquisition expenses, noninterest expense is expected to be between $31 million and $33 million in 4Q25. nAsset quality expected to remain solid, although a return to more normalized asset quality metrics and charge-offs may continue should the economy soften. Additionally, large changes in the outlook for unemployment and GDP may drive more volatility in the CECL calculation.
