Highlights

How we pick these

Strengths

  • Strong cash generation. 34.4% of revenue turned into free cash flow.
  • Shrinking share count. Diluted shares fell 2.0% in a year, so each share owns more of the business.
  • Net cash. Cash exceeds long-term debt by $0.1bn.

Things to watch

  • Revenue shrinking. Revenue fell 51.7% over the last 12 months.
  • Growth slowing. The growth rate is 25.5 points lower than a quarter earlier.
  • Below peers: stock pay as % of revenue. Stock pay as % of revenue of 3.8% ranks 199 of 206 regional banks companies we cover (median 1.3%).
  • Missing expectations. Earnings per share fell short of the consensus estimate in 2 of the last four quarters.
  • Estimates being cut. Analysts' consensus for next year's earnings per share has fallen 12.4% over 90 days.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

We value Mainstreet Bancshares, Inc. as a bank or lender, with every model that fits that kind of business. Cost of equity 8.3%: the 10-year Treasury yield (4.9%) plus a beta of 0.74 times a 4.5% equity risk premium.

Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$24 ~$16–$38 Primary model, counts double
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$24 ~$20–$29 Included

Dividend discount (two-stage) Dividends for five years at the growth the business can fund, then a steady payout and growth. ~$25 ~$20–$31 Included
Combined value Weighted average of the models that apply: the primary model (residual income) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$24 ~$21–$32 6 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Mainstreet Bancshares, Inc. with banks and lenders in our coverage, using third-party market data. Model values are estimates under stated assumptions, updated as new filings arrive; not price targets or investment advice. How each model works.

Moat

57 /100

Moderate moat

How hard Mainstreet Bancshares's competitive advantage looks for rivals to wear away, judged from 8 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 11 / 20

    Net income has been a median 1.0% of total assets over 8 years.

  • Durability 9 / 20

    Net margin has been a median 28.5%; its worst year was -6.3%.

  • Discipline 17 / 20

    The diluted share count fell 3.6% over five years; stock-based pay has been a median 2.8% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (62 before it).

A rules-based reading of reported figures, not a forecast and not investment advice. How the score is built: methodology.
