MainStreet Bancshares, Inc. Reports Third Quarter 2026 Results

Relationship banking drives growth in net interest income

Fairfax, VA., October 26, 2026 – MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the financial holding company for MainStreet Bank, reported net income of $3.6 million for the quarter-ended September 30, 2026, resulting in earnings per common share of $0.43. The net interest margin was 3.55% for the quarter, up two basis points from the previous quarter. Net interest income increased to $18.8 million for the quarter, marking the fourth consecutive quarterly increase.

During the quarter the Bank exercised targeted credit remediation by adding a $1.9 million provision for credit losses, an impact on earnings per common share of ($0.21). The Company and Bank remain well-capitalized with strong liquidity.

"No sector is entirely immune to broader economic realignments, and we are managing through commercial real estate adjustments with eyes wide open," said Jeff W. Dick, Chairman and CEO of MainStreet Bancshares, Inc. and MainStreet Bank.

Chris Johnston, Chief Credit Officer of MainStreet Bank added, "resolving credit challenges in a transitioning commercial real estate environment requires active engagement and patience. We are methodically working through nonperforming assets and prioritizing long-term portfolio quality over short-term expediency. Management continues to actively stress-test the credit portfolio, engage with borrowers, and enforce strong recourse structures."

"A stabilizing D.C. market reinforces the value of our core relationship banking model," added Abdul Hersiburane, President of MainStreet Bank. "As local economic conditions improve, we remain focused on deploying capital prudently, working with well-capitalized borrowers, supporting sound commercial developments, and converting market transition into long-term shareholder value."
