[424B3] FIRST COMMUNITY BANKSHARES INC /VA/ Prospectus Filed Pursuant to Rule 424(b)(3)

Rhea-AI Filing Summary

First Community Bankshares filed a prospectus supplement to its S-4 merger materials and reported a key regulatory step for its acquisition of Hometown Bancshares. On November 6, 2025, the Federal Reserve Bank of Richmond approved the merger of Hometown’s Union Bank, Inc. into First Community Bank, and granted a waiver from filing an additional Bank Holding Company Act application.

The filing notes prior “no objection” from the West Virginia Division of Financial Institutions. The merger still requires approval from the Virginia State Corporation Commission Bureau of Financial Institutions, a vote of Hometown’s shareholders, and other customary conditions. The supplement also corrects the proxy disclosure to state that “Institution A” proposed a 100% cash transaction at a lower valuation than First Community’s indication of interest. First Community’s shares closed at $33.29 on November 11, 2025.

Insights

Bank M&A analyst

Regulatory progress for FCBC–Hometown merger; terms clarification.

First Community Bankshares (FCBC) reported Federal Reserve approval for merging Hometown’s Union Bank into First Community Bank, alongside a waiver from filing an additional BHC application. This removes a major federal gating item in a bank merger sequence.

The transaction still depends on the Virginia banking regulator, Hometown shareholder approval, and standard closing conditions. The company also corrected its proxy to clarify that a rival, Institution A, offered a 100% cash deal at a lower valuation than FCBC’s indication of interest.

Actual closing and integration timing will depend on the remaining approval and the shareholder vote; the excerpt lists no further dates. Subsequent company disclosures may provide closing specifics.

Receipt of Regulatory Approval from the Federal Reserve Bank of Richmond

On November 6, 2025, First Community Bankshares, Inc. (“First Community”) received regulatory approval from the Federal Reserve Bank of Richmond, acting on delegated authority from the Board of Governors of the Federal Reserve System, to merge Union Bank, Inc., a wholly-owned subsidiary of Hometown Bancshares, Inc. (“Hometown”), with and into First Community Bank, a wholly-owned subsidiary of First Community (the “Bank Merger”) in connection with the previously announced merger (the “Merger”) of Hometown with and into First Community pursuant to the Agreement and Plan of Merger dated July 19, 2025 (the “Merger Agreement”), by and between First Community and Hometown. In addition, the Federal Reserve Bank of Richmond approved First Community’s request for a waiver from the requirement to file an application under the Bank Holding Company Act of 1956 to acquire Hometown pursuant to the Merger Agreement. The West Virginia Division of Financial Institutions previously issued a no objection to the Merger and the Bank Merger. The Merger and the Bank Merger remain subject to the approval from the Virginia State Corporation Commission Bureau of Financial Institutions, Hometown’s shareholders and other customary closing conditions.

Amendment and Supplement of the Proxy Statement/Prospectus

In connection with the Merger, First Community filed a proxy statement/prospectus on Form S-4 (File No. 333-290201) (the “Proxy Statement/Prospectus”), which automatically became effective on October 27, 2025, and was first mailed or otherwise delivered to the shareholders of Hometown on or about October 28, 2025. Defined terms used but not defined herein have the meanings set forth in the Proxy Statement/Prospectus and all page references are to pages in the Proxy Statement/Prospectus.

First Community is filing this Current Report on Form 8-K to amend and supplement the Proxy Statement/Prospectus in order to correct an error in the Proxy Statement/Prospectus concerning the indication of interest received by Hometown from Institution A. The correction to the existing disclosure in the Proxy Statement/Prospectus is set forth below. Other than this correction, the Proxy Statement/Prospectus remains unchanged, and this supplement does not otherwise amend, supplement, or affect the Proxy Statement/Prospectus. From and after the date of this supplement, any references to the “Proxy Statement/Prospectus” are to the Proxy Statement/Prospectus as amended and supplemented by this supplement. This supplement should be read in conjunction with the Proxy Statement/Prospectus and the other proxy materials previously made available to shareholders in connection with the Hometown special meeting. If you have already voted your shares, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal.

Error Correction (Page 34 Proxy Statement/Prospectus). The second sentence of the second paragraph on page 34 of the Proxy Statement/Prospectus is hereby amended and restated in its entirety to read:

“Institution A proposed a 100% cash transaction and valued Hometown at a lower valuation than the terms of First Community’s indication of interest, discussed below.”

On November 12, 2025, Hometown sent a letter to its shareholders addressing the aforementioned correction. A copy of the letter is attached hereto as Exhibit 99.1.
