First Guaranty Bancshares, Inc. (“FGBI” or the “Corporation”) (NASDAQ: FGBI), the parent company of First Guaranty Bank, announced today the pricing of its underwritten public offering (the “Offering”) of 1,200,000 depositary shares, each of which represents a 1/40th interest in a share of its 6.75% Series A Fixed-Rate Non-Cumulative Perpetual Preferred Stock, $1,000 liquidation preference per share (equivalent to $25.00 per depositary share). The Corporation has granted the underwriter an option, exercisable in whole or in part for 30 days, to purchase up to an additional 180,000 depositary shares at the public offering price, less the underwriting discount. The Corporation expects to close the Offering, subject to customary conditions, on or about April 27, 2021.

The Corporation has filed an application to list the depositary shares on the Nasdaq Global Market (“Nasdaq”) under the symbol “FGBIP”. If the application is approved, trading of the depositary shares on Nasdaq is expected to begin within 30 days after the closing date.

FGBI expects the gross proceeds from the Offering to be $30,000,000 million (or $34,500,000 million if the underwriter exercises its option to purchase additional depositary shares in full). Net proceeds to the Corporation, after deducting the underwriting discount but before deducting estimated offering expenses and fees payable by the Corporation, are expected to be $28,950,000 million (or $33,292,500 million if the underwriters exercise their option to purchase additional depositary shares in full). The Corporation intends to use the net proceeds from the Offering for general corporate purposes, which may include working capital and the funding of organic growth or potential acquisitions.

Janney Montgomery Scott LLC is serving as sole book-running manager for the Offering.

The depositary shares are being offered pursuant to an effective shelf registration statement on Form S-3 (File No. 333-249169) the Corporation filed with the Securities and Exchange Commission (the “SEC”), which was declared effective by the SEC on October 26, 2020, and only by means of a prospectus supplement and accompanying prospectus.
