MainStreet Bancshares Inc. Reports Third Quarter Results

Increase in Core Deposits, a High Quality Loan Portfolio and Strong Capital

Fairfax, VA., October 28, 2024 — MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the financial holding company for MainStreet Bank, reported a loss of -$0.04 per common share for the third quarter of 2024 as it dealt decisively with a small number of nonperforming real estate loans. Year-to-date 2024 earnings per common share are $0.60. The Company remains strongly capitalized.

“Our third quarter annualized net interest margin was impacted by $984,000 in accrued interest income that was reversed in relation to loans placed on nonaccrual status,” said Alex Vari, Chief Accountant for MainStreet Bank. “This resulted in a quarterly net interest margin of 3.05% and a year-to-date net interest margin of 3.19%.”

The Company charged off $1.9 million of nonperforming loans during the quarter and allocated $1 million to provision expense to augment loan growth and ensure the Allowance for Credit Losses remains directionally consistent for the purposes of growth and quality.

In response to the bank’s credit quality, Chris Johnston, Chief Credit Officer for MainStreet Bank, expanded, “this quarter showed the underlying strength of a portfolio shaped by a rigorous credit culture. The total principal losses incurred year-to-date 2024 approximates just 0.1% of total loans. Our lending team has demonstrated great resolve in addressing troubled loans, both by working with borrowers and by finding acceptable solutions minimizing the impact on shareholder value. With that, we expect the level of problem loans to improve from this point.”

Total deposits expanded to $1.9 billion. The Bank continues to attract healthy amounts of core deposits, reaching $1.47 billion, or 78% of total deposits.

“The DC Metropolitan area is a vibrant market. Our Business Bankers continue to perform, growing noninterest bearing core deposits by $33 million during the quarter,” noted Abdul Hersiburane, President of MainStreet Bank. “In an exercise of foresight, we structured noncore deposits with immediate rate repricing or callable options. We have now $233 million of our $423 million noncore deposits available to reprice as rates fall.”

In 2021, the Board and management decided to make an investment in technology that would best serve clients requiring Banking-as-a-Service (BaaS). The Avenu BaaS solution officially launched just prior to the end of the third quarter of 2024. The ability to digitally offer banking services in a safe and compliant manner allows the Company to reach new customer deposit segments, diversify revenue streams and generate additional income. The BaaS market is currently underserved, and the opportunities for a well-developed solution are robust. The Avenu business model is in-line with the Company’s physical branch-lite strategy.

“Avenu provides a full-stack embedded banking solution that connects our partners and their apps directly and seamlessly to our purpose-built Avenu core,” said Jeff W. Dick, Chairman & CEO of MainStreet Bancshares, Inc. and MainStreet Bank. “With Version 1 of Avenu placed in-service, the team is focused on getting the first fintech to general release in early November, and another four fintechs to follow soon thereafter. Just as with any business expansion opportunity, the expenses associated with launching Avenu will impact profitability until we reach break-even. However, after that point Avenu’s ability to digitally scale can far surpass bricks and mortar growth and profitability.”

Avenu’s clients are fintechs, social media solutions, application developers, money movers, and entrepreneurs. They all have one thing in common: They are in search of a reliable partner to help innovate how money moves - solving real-world issues and helping communities thrive. MainStreet Bank is that reliable partner dedicated to providing a best-in-class solution to sustain long-term business relationships.
