MainStreet Bancshares, Inc. Reports Strong Net Income as Interest Rates Rise

Fairfax, Virginia – July 25, 2022 - MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the holding company for MainStreet Bank, said its net interest margin widened as rates climbed in recent months, driving strong net income for the second quarter and six months ended June 30, 2022.

The Bank’s loan portfolio is well positioned for increasing interest rates. “The FOMC’s next announcement is due to be released on July 27 and based upon Street consensus we anticipate continued net interest margin expansion,” said Jeff W. Dick, Chairman & CEO of MainStreet Bancshares, Inc. and MainStreet Bank.

“We have been anticipating this trend for some time and we strategically aligned our portfolio to flex as the economy shifts,” Dick said. “Even as we focus on maintaining a rigorous credit culture, we are constantly looking to the future, sharpening our understanding of what clients demand in an evolving financial services market, and choosing to innovate.”

A focal point of MainStreet Bank’s innovation is its Avenu™ Software as a Service (SaaS) and Banking as a Service (BaaS) platform. Dick and other MainStreet Bank executives will discuss quarterly and half-year earnings and preview business developments at Avenu™ during a virtual webcast and quarterly earnings call at 2 p.m. Eastern time today.

Net income totaled $5.9 million for three months ended June 30, and $11.4 million for the six months ended June 30. Net interest income totaled $16.1 million in the second quarter, 6% higher than the immediately preceding quarter and 24.1% higher than the comparable period in 2021.

Rising interest rates propelled the net interest margin higher by 75 basis points to 3.95% for the quarter ended June 30, versus 3.20% a year earlier, on a tax equivalent basis. The Company’s efficiency ratio remains solid at 55%. Total assets reached $1.8 billion in the second quarter, a 5.0% increase from a year earlier.

Quarterly results represent:

	•	12.59% return on average equity
	•	1.39% return on average assets
	•	$0.71 earnings per share of common stock (basic and diluted)
	•	$21.41 per common share book value

The level of Accumulated Other Comprehensive Income (AOCI) for the Company is low at -$6.56 million. The level is consistent with the size and quality of the investment portfolio, as the Bank enjoys consistent strong in-market loan demand.

The average loans outstanding rose just over 4% since the first quarter of 2022, as the bank was able to capitalize on continued demand in a higher interest rate environment. Asset quality remains pristine, as the Company had zero non-performing assets as of quarter ended June 30. Noninterest-bearing deposits represent 36% of the $1.5 billion in total deposits, and 70% of total deposits are core deposits.

“We operate in a robust market in Northern Virginia and the Washington Metropolitan area, and loan demand remains steady,” said Abdul Hersiburane, president of MainStreet Bank. “The surge in loan volume that occurred for banks nationwide during the height of the COVID crisis has normalized, and what we are seeing now is solid, steady, organic loan growth that reflects the confidence of businesses in this marketplace that they have opportunities to grow.” He noted that federal Paycheck Protection Program loans now represent a negligible 0.3% of the bank’s loan portfolio.

Avenu™

Avenu™, a division of MainStreet Bank, which provides Software as a Service (SaaS) and Banking as a Service (BaaS), continued to generate significant customer interest as additional fintechs joined the queue for our proprietary software solution. We are currently onboarding our initial beta customer with an anticipated go-live date in the fourth quarter of 2022.

“Fintechs have a strong need for knowledgeable, credible partners who can help them manage risk and compliance obligations,” said Todd Youngren, President of Avenu™. “Preparing them to become fully compliant is a critical, intensive element of this process, and we are focusing our energy on getting that right. Following the beta stage, we anticipate that onboarding will be streamlined into a 60-day process.”

Youngren noted that at the end of the first quarter, Avenu™ had 10 fintechs queued up at various stages of progress, including four that have indicated they intend to move forward as soon as the beta process is complete. These prospects include entities that serve the domestic needs of foreign nationals and entities that serve the education and nonprofit industries. Avenu has another 36 fintechs that have signed up to be “in the queue,” and 128 fintechs that have signed up to receive updates and are actively monitoring our progress.

In addition to serving fintechs, the Avenu™ team has a robust array of existing customers that include payment processors and money service businesses. These relationships have been integral in identifying the needs and services that fintechs need banks to provide in order to have successful partnerships. These relationships provide the Bank with additional noninterest income and a strong source of low-cost deposits that can be integrated into the Bank’s traditional source of income generation, net interest margin. As a benchmark, Youngren noted, Avenu™ is favorably impacting profitability, with its customers providing $70 million in noninterest bearing deposits and $488,000 in noninterest income in the six months ended June 30, 2022.
