EXPLANATORY NOTE/DEREGISTRATION OF SECURITIES

This Post-Effective Amendment (the "Amendment No. 1"), filed by Glen Burnie Bancorp, a Maryland corporation (the "Company") relates to the Registration Statement on Form S-3 (File No. 333-181328), (the "Registration Statement") registering 150,000 shares of the Company's common stock, par value $1.00 per share (the "Shares") which were offered to the Company's shareholders who elected to reinvest Company dividends under the Company's Dividend Reinvestment and Stock Purchase Plan (the "Plan"). The Registration Statement was filed with the Securities and Exchange Commission (the "Commission") on May 11, 2012, as amended by Pre-effective Amendment No. 1 ("the Pre-effective Amendment" and, together with the Registration Statement, the "Existing Registration Statement").

On December 12, 2025, the Company announced that it notified The Nasdaq Capital Market LLC ("Nasdaq") of its intention to delist the Shares from Nasdaq and that it intended to thereafter deregister the Shares under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). On December 22, 2025, the Company filed a Form 25 to delist the Shares from Nasdaq, and intends to file a Form 15 with the Commission on January 2, 2026, which will suspend the Company's obligations to continue to file periodic and current reports with the Commission pursuant to Section 13 of the Exchange Act. The de-registration will become effective ninety (90) days after the Form 15 is filed with the Commission.

In connection with the Company's voluntary decision to delist and deregister, it has terminated any and all offerings pursuant to the Existing Registration Statement. Accordingly, pursuant to an undertaking made by the Company in Part II of the Existing Registration Statement, the Company is filing this Amendment No. 1 to remove from registration any securities that had been registered for issuance but remain unsold at the termination of the offering. The Company, by filing this Amendment No. 1, hereby removes from registration any and all securities registered but unsold under the Existing Registration Statement as of the date hereof. The Existing Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.

Pursuant to Rule 464(a) promulgated under the Securities Act of 1933, as amended (the "Securities Act"), this Amendment No. 1 shall become effective upon it being filed with the Commission.
