"Our core net interest margin is a healthy 3.54% for the third quarter of 2025. Our balance sheet is well-structured for current and anticipated rate changes to continue producing good results," said Alex Vari, Chief Financial Officer of MainStreet Bank. "The outlook for the Bank remains strong, as our team continues to focus on core revenue generation and expense control." "We continue to see quality opportunities to lend in the government contracting, commercial real estate, construction and owner-occupied space," said Tom Floyd, Chief Lending Officer of MainStreet Bank. "We've worked with a few of our borrowers to improve their credit relationship, and as a result I'm happy to report that we continue to show strong asset quality. Finally, we've been talking with our customers regularly about the shutdown, and they know we stand ready to help them with their financial needs."

This new stock repurchase program will replace and supersede the Company's existing stock repurchase program which was originally announced on May 19, 2022.
