Year-End and Fourth Quarter Results Underscore Steady Progress in Challenging Environment

FAIRFAX, Va., Jan. 22, 2024 /PRNewswire/ -- MainStreet Bancshares, Inc. (Nasdaq: MNSB & MNSBP), the holding company for MainStreet Bank, reported net income of $26.6 million for the year ended December 31, 2023, consistent with expectations. Earnings per share for the year totaled $3.25.

Annualized returns for 2023 included:

Return on Average Equity (ROAE):	12.66 %
Return on Average Assets (ROAA):	1.38 %
Net Interest Margin (NIM) (tax equivalent):	4.08 %
Efficiency Ratio:	56.7 %
Liquidity Coverage Ratio:	133 %
Core Deposit Ratio:	74 %
FDIC Insured Deposits / Total Deposits:	77 %
Allowance for Credit Losses (ACL):	1.01 %
Tangible Book Value per Common Share:	$23.86

"We've maintained a steady course, meeting customer credit needs and delivering healthy shareholder value at a time when community banks across our region and the nation face intense headwinds," said Jeff W. Dick, Chairman and CEO of MainStreet Bancshares Inc. and MainStreet Bank.

"It's worth reflecting on what an extraordinarily challenging year this was," he continued. "In the first quarter of 2023, we witnessed the second, third, and fourth largest bank failures in U.S. history. The fallout increased the impact of historically steep interest rate hikes. Yet MainStreet Bancshares has not just persevered but prospered. We see a bright future for all facets of our business, and we continue to invest in innovation as our Avenu embedded banking solution comes to fruition."

Strong Fundamentals"Our core banking business is thriving," added Abdul Hersiburane, MainStreet Bank's President. "Core deposits rose to 74% in the fourth quarter, up from 68% in the third quarter, and in the same period our wholesale deposits declined from 31% to 24%. Net loans, meanwhile, were up 8% for the year."

The Company's loan book totaled $1.73 billion at the end of 2023, and concentrations are well managed, with commercial real estate standing at 373% of total capital, below the board-set limit of 375%. The quality of the loan portfolio remained pristine, with negligible net chargeoffs and past-due loans.

The cumulative net interest margin rested at 4.08% for the year, as funding costs began to stabilize. While this measure has trended down quarter over quarter, the Company's levels have consistently remained higher than most of its peers due to strong balance sheet management.

Fortifying Avenu for GrowthSince it went live in the third quarter, Avenu has continued to make progress in attracting and onboarding customers. Its inaugural client, Safari Pay, has now entered the beta stage and is gradually adding customers and conducting transactions. As Avenu ramps up and begins compliance reviews and onboarding with additional customers, the team will continue to harden and test systems and fortify the operation to scale up.

"We set out to build from scratch a compliance-centric system that can connect our partners and their apps directly and seamlessly to MainStreet Bank's banking core," Dick noted. "This was never a modest task because we weren't interested in jumping onboard the middleware bandwagon. We wanted to build our embedded banking solution with meticulous care, bringing our deep understanding of regulatory and business challenges to bear. We are confident that our embedded banking solution will prove innovative and enhance MainStreet Bank's deposit growth and support expanded lending."

ABOUT AVENUAvenu, MainStreet Bank's fully integrated Software as a Service (SaaS) solution, identified its first client on October 18. SafariPay, via its global money transmittance service PaySii, expects its customers to maintain average balances of $4 million on the platform.

Avenu — Banking Delivered Avenu is the only embedded banking solution that connects our partners and their apps directly and seamlessly to a banking core — MainStreet Bank's banking core. We are not a sponsor bank without our own technology, and we are not a middleware software company (aggregator) without our own bank.

They all have one thing in common: They are innovating how money moves to solve real-world issues and help communities thrive.
