Item 8.01 Other Events.

On May 6th, 2025, Mainstreet Bancshares Inc, issued a statement regarding recent inquiries received.

We received a few inquiries regarding Director nominee Ali Reza Manouchehri, the CEO of MetroStar Systems, LLC (MetroStar), and the work MetroStar performed on the Avenu platform. We thought it would be beneficial for shareholders to know the answers.

MetroStar is a successful award-winning mid-sized company that has been a leading provider of digital IT services and solutions for the public sector since 1999. MetroStar partnered with Object Computing, Inc. (OCI) to design and build the Avenu platform, starting in May 2021.

The Avenu team planned to expand in size and bring the solution in-house, with a transition date set for June 30, 2023. We contracted with MetroStar and OCI to retain a few key resources to assist with the transition through the end of 2023. It's important to note that MainStreet Bank has not engaged MetroStar or OCI for any work since December 31, 2023.

Mr. Manouchehri joined our Bank Board of Directors on February 21, 2024. Since his appointment, the only reportable compensation he has received is his standard Board compensation. MetroStar did not earn any compensation from MainStreet Bank in 2024 or in the year-to-date period of 2025.

Mr. Manouchehri brings a wealth of knowledge and experience to our Board in technology and innovation, government and commercial contracting, application development, business development, and venture capital funding. Furthermore, Mr. Manouchehri has been a valued customer of MainStreet Bank since the very early days and has provided many leads to our lenders and business bankers over the years.

The information furnished under Item 8.01 of this Current Report on Form 8-K, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, and it shall not be deemed incorporated by reference in any filing under the Exchange Act, or the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such filing to this Form 8-K.
