Bank CFO to Assume Company CFO Title and Responsibilities

FAIRFAX, Va., Nov. 26, 2025 /PRNewswire/ -- MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the Financial Holding Company for MainStreet Bank, announced that Thomas J. Chmelik will retire as the Chief Financial Officer of MainStreet Bancshares, Inc. on December 31, 2025. He will continue to serve as the Senior Executive Vice President and Secretary of the Bank and Company through December 31, 2027.

Mr. Chmelik is a co-founder of MainStreet Bank, which opened in May 2004. Chmelik is a career banker having served as the CFO of four successful community banks in the Washington, DC market as well as working on a World Bank initiative to restructure the National Bank of Commerce – the largest commercial bank in Tanzania, Africa.

"Co-founding and building MainStreet Bank has been the highlight of my banking career," said Tom Chmelik. "There were 7,767 bank charters in the beginning of 2004 and that number declined by almost 43% over the past 21 years. There is still a strong need for community banks in this country – as we provide the majority of financing for small businesses. I plan to remain on both the Company and Bank Boards and will stay engaged with the leadership team in a reduced capacity."

"I feel very fortunate to have worked side-by-side with Tom to establish and build MainStreet Bank," said Jeff W. Dick, Chairman & CEO of MainStreet Bancshares, Inc. and MainStreet Bank. "Tom is an unconventional CFO - he's as comfortable behind the desk as he is out in the community sourcing new loan and deposit opportunities for the team. I'm especially proud of the job Tom did in preparing our Bank CFO Alex Vari to assume the role as Company CFO upon his planned retirement."

"I'm excited for the opportunity to step into the Company CFO position," said Alex Vari, CPA, CFO and Executive Vice President of MainStreet Bank. "Tom has given me the opportunity to lead our financial preparation and public disclosures, as well as interact with our investor community over the past several years. I'm confident that the team will continue to maintain the high standards that Tom established."
