ARR ARMOUR Residential REIT Inc New

ARMOUR Residential REIT, Inc. (NYSE: ARR and ARR-PRC) (“ARMOUR” or the “Company”) today announced that its Board of Directors has approved a reverse stock split of ARMOUR's outstanding shares of common stock at a ratio of one-for-five and the September 2023 dividend for the Company's Common Stock. The Company today also announced guidance on common stock dividends for the fourth quarter of 2023.

One-for-Five Reverse Stock Split

The reverse stock split is scheduled to take effect at about 5:00 p.m. Eastern Time on September 29, 2023 (the "Effective Time"). At the Effective Time, every five issued and outstanding shares of common stock of the Company will be converted into one share of common stock of the Company. In addition, at the Effective Time, the number of authorized shares of common stock will also be reduced on a one-for-five basis. The par value of each share of common stock will remain unchanged. Trading in ARMOUR's common stock on a split adjusted basis is expected to begin at the market open on October 2, 2023. ARMOUR's common stock will continue trading on the NYSE under the symbol "ARR" but will be assigned a new CUSIP number. The Company believes that existing stockholders will benefit from the ability to attract a broader range of investors as a result of the reverse stock split and a higher per share stock price.

As a result of the reverse stock split, the number of outstanding shares of ARMOUR's common stock as of August 29, 2023, will be reduced from approximately 237,356,720 to approximately 47,471,344. As discussed further below, the monthly common dividend rate is expected to remain stable at an adjusted rate of $0.40 per share. Concurrently, the authorized number of shares of common stock will be reduced from 450,000,000 to 90,000,000. The number of shares of ARMOUR’s Series C Preferred Stock outstanding, their preference amount and dividend rate are not affected by this reverse stock split.

No fractional shares will be issued in connection with the reverse stock split. Instead, each stockholder holding fractional shares will be entitled to receive, in lieu of such fractional shares, cash in an amount determined on the basis of the average closing price of ARMOUR's common stock on the NYSE for the three consecutive trading days ending on September 29, 2023. The reverse stock split will apply to all of ARMOUR's authorized and outstanding shares of common stock as of the Effective Time. Stockholders of record will be receiving information from Continental Stock Transfer & Trust Company, ARMOUR's transfer agent, regarding their stock ownership following the reverse stock split and cash in lieu of fractional share payments, if applicable. Stockholders who hold their shares in brokerage accounts or "street name" are not required to take any action in connection with the reverse stock split.
