MainStreet Bancshares Inc. Reports a Profitable Second Quarter

Rise in Core Deposits Fueled an Uptick in Loan Growth

FAIRFAX, Va., July 29, 2024 /PRNewswire/ -- MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the holding company for MainStreet Bank, reported net income of $2.6 million for the second quarter of 2024.

Total deposits reached $1.8 billion in the second quarter, an increase of 10.2% from the second quarter of 2023. Loan growth is up 8.6% over the same period, also reaching $1.8 billion.

"We are now nine full quarters into the current interest rate cycle, and the entire industry has felt the effect of higher deposit costs. I'm happy to report that we experienced the softest impact this quarter, with our net interest margin settling in at a healthy 3.15%," said Jeff W. Dick, Chairman and CEO of MainStreet Bancshares, Inc. and MainStreet Bank. "We see signs of an improving net interest margin going forward, but FOMC actions or other unforeseen externalities could affect momentum. Externalities aside, as our strategic initiatives start to bear fruit, we are confident and optimistic that the trail we have blazed to offer Banking as a Service (BaaS) will positively affect our net interest margin and our bottom line."

"We remain focused on caring for our customers and meeting their continuing banking and borrowing needs while judiciously adding promising new relationships," said Abdul Hersiburane, President of MainStreet Bank. "We've built our core customer funding sources up to 78% of total deposits."

Loan growth in the second quarter was driven by a healthy rise in demand for commercial and industrial borrowing and in high-quality owner-occupied commercial real estate lending, a traditional area of strength for MainStreet Bank.

The Bank maintains a strong portfolio of earning assets, with very nominal AOCI exposure. The loan portfolio remains solid with net charge offs representing a mere eight basis points of average gross loans. Nonperforming assets account for 0.99% of total assets.

"We continue to carefully underwrite each loan opportunity and the lending team remains engaged with each borrower throughout their project lifecycle. If a borrower experiences a challenge, we work with them to face that challenge promptly and transparently," said Tom Floyd, EVP and Chief Lending Officer at MainStreet Bank. "We have a meticulous understanding of our loan book and a rigorous risk management mindset."
