Here are the 424B prospectus supplements from John Marshall Bancorp, Inc. (JMSB) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow JMSB and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full JMSB filings page.
John Marshall Bancorp (JMSB) currently expects to issue approximately 10,823,230 shares of common stock in its proposed merger with Eagle Financial Services (EFSI), based on EFSI shares and restricted stock awards as of September 7, 2026, and assuming all unvested EFSI awards elect JMSB shares; the actual issuance may change with EFSI’s outstanding share count before completion. If completed, each eligible EFSI share converts into 2.00 JMSB shares, with cash paid for fractional shares. The implied value was $46.02 per EFSI share on October 13, 2026.
The transaction also combines EFSI’s Bank of Clarke with John Marshall Bank, with John Marshall Bank surviving. Completion requires JMSB shareholders to approve the share issuance and EFSI shareholders to approve the merger; EFSI approval requires at least two-thirds of outstanding shares entitled to vote. Both virtual meetings are scheduled for November 19, 2026. The companies expect completion in the first quarter of 2027, subject to shareholder and regulatory approvals and other closing conditions. The fixed exchange ratio means the consideration’s market value will fluctuate with JMSB’s share price.
