FAIRFAX, Va., April 20, 2026 (GLOBE NEWSWIRE) -- MainStreet Bancshares, Inc. (NASDAQ:MNSB, MNSBP)), the financial holding company for MainStreet Bank, reported a net income of $4.1 million for the quarter-ended March 31, 2026, resulting in earnings per common share of $0.48. The net interest margin expanded 9 basis points during the quarter to 3.47%, resulting from consistent loan pricing and lower funding costs.

During the quarter the Company executed a buyback of 273,448 shares, and the book value per common share ended the quarter at $25.63. The Company and Bank remain strongly capitalized.

"Our team's disciplined execution continues to drive value for our shareholders. With robust liquidity and a growing book value, we leveraged our share buyback program to take advantage of accretive opportunities in the market. At the same time, we remain focused on delivering strong and sustainable earnings growth," said Jeff W. Dick, Chairman and CEO of MainStreet Bancshares, Inc. and MainStreet Bank.

"We continue to replace higher cost funds with lower cost deposits which is a key driver of our expanding net interest margin," said Alex Vari, CFO of MainStreet Bancshares, Inc. and MainStreet Bank. "We've seen our eighth straight quarter with improvement in our total cost of deposits. This is a testament to our diligence in structuring noncore deposits while our business bankers maintain and grow valuable relationships within our community. Total core funding is $1.4 billion and total deposits grew to over $1.9 billion."

"Net loans increased for the quarter to $1.85 billion resulting in a well-managed 98% loan-to-deposit ratio. We're pleased to have grown our owner-occupied commercial real estate book by $79 million year-over-year. Our owner-occupied relationships also bring good deposit balances, which helps to maximize the value of our customer relationships," said Tom Floyd, Chief Lending Officer of MainStreet Bank.

Nonperforming assets as a percentage of total assets settled at 2.47% while loans 30-89 days past due and accruing improved to 0.95%. In response, Chris Johnston, Chief Credit Officer of MainStreet Bank, added, "We have a strong credit culture and a comprehensive underwriting process. The loans we are currently working to resolve are secured by properly leveraged real estate with personal guarantees. Our primary objective is to work with borrowers to resolve loans that have elevated risk without exposing the Bank to a loss of principal. Our team's track record on resolutions is strong – with a total accumulated principal loss of less-than $10 million over the entire 22-year history for the commercial loan portfolio."
