USCB Financial Holdings, Inc. Reports Fourth Quarter 2021 Results and Announces Share Repurchase Program

MIAMI – January 27, 2022 – USCB Financial Holdings, Inc. (the “Company”) (NASDAQ: USCB), reported net income of $5.7 million or $0.30 per diluted share for the three months ended December 31, 2021, compared with net income of $4.2 million or $0.67 and $0.14 per diluted share for Class A and Class B common stock, respectively, for the same period in 2020. Net income for the year ended December 31, 2021, was $21.1 million or $(6.72) per diluted common share compared with net income of $10.8 million or $1.50 and $0.30 per diluted share for Class A and Class B common stock, respectively, for the same period in 2020.

Operating net income per diluted share (non-GAAP) for the year ended December 31, 2021 was $1.81 compared to operating net income per diluted share (non-GAAP) for the same period in 2020 of $1.50 and $0.30 for Class A and Class B common stock, respectively. Operating net income per diluted share (non-GAAP) for the year ended December 31, 2021 excludes the $89.6 million one-time accounting impact of the exchange and redemption of the preferred shares. A reconciliation of non-GAAP measures to GAAP measures appears at the end of this press release.

On December 21, 2021, the Company entered into agreements with the Class B shareholders to exchange all outstanding Class B non-voting common stock for Class A voting common stock at a ratio of 5 to 1. On the same day, a total of 6,121,052 shares of Class B common stock was exchanged for 1,224,212 shares of Class A common stock. As of December 31, 2021, the Company’s only class of shares issued and outstanding were Class A common stock.

Effective December 30, 2021, the Company became the parent bank holding company of U.S. Century Bank (the “Bank”). Each share of the Bank was exchanged for one share of the Company, making the Bank a wholly owned subsidiary of the Company. Shares of the Company continue to trade under ticker symbol “USCB” on the Nasdaq Global Market. Due to the reorganization, the Company is subject to periodic filings with the Securities Exchange Commission (“SEC”) instead of the Federal Deposit Insurance Corporation (“FDIC”). As of December 31, 2021, all the business of the Company is conducted by the Bank.

On January 24, 2022, the Board of Directors approved a share repurchase program of up to 750,000 shares of Class A common stock. Under the repurchase program, the Company may purchase shares of Class A common stock on a discretionary basis from time to time through open market repurchases, privately negotiated transactions, or other means. The repurchase program has no expiration date and may be modified, suspended, or terminated at any time. Repurchases under this program will be funded from the Company’s existing cash and cash equivalents or future cash flow.

“Over the course of 2021, we achieved many notable milestones thanks to the unwavering commitment and support from our employees, customers, and partners. Together, we were able to complete an IPO, simplify our capital structure, and form a bank holding company. We continue to grow and remain very optimistic about our future.” said Luis de la Aguilera, President and Chief Executive Officer. “The formation of the holding company provides more efficient access to capital while allowing flexibility for growth and acquisition strategies. We believe that forming a holding company places us in the best position to respond to evolving market conditions and enables us to take advantage of future opportunities.”

(1) The Company believes these non-GAAP measurements are a key indicator of the ongoing earnings power of the Company.
(2) For the quarter ended September 30, 2021, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive.
(3) During the quarter ended December 31, 2021, the Company entered into agreements with the Class B shareholders to exchange all outstanding Class B non-voting stock for Class A voting common stock at a ratio of 5 to 1. In calculating net income (loss) per diluted share for the prior quarters presented, the allocation of operating net income available to common stockholders was based on the weighted average shares outstanding per common share class to the total weighted average shares outstanding during each period. The operating net income allocation was calculated using the weighted average shares outstanding of Class B common stock on a as-converted basis.
