Item 8.01. Other Events.
In anticipation of its filing one or more registration statements on Form S-3, MFA Financial, Inc. (the “Company”) is filing this Current Report on Form 8-K to incorporate by reference the recast presentation of certain financial information and related disclosures included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2022 (the “2021 Form 10-K”), to reflect (i) the effects of the Company’s 1-for-4 reverse stock split of the Company's common stock effected on April 4, 2022, and (ii) the Company’s change in reportable segments, which was reported in its Quarterly Report on Form 10-Q for the quarter ended June 30, 2022, filed with the SEC on August 4, 2022. This recast financial information is filed herewith to incorporate such information by reference into the Company’s future filings under the Securities Act of 1933, as amended.
In the second quarter of 2022, the Company changed its financial reporting to two reportable segments comprised of (i) mortgage-related assets and (ii) Lima One, as described in Exhibit 99.1 (Note 16 to the consolidated financial statements). This new alignment replaced the Company’s historical reporting of a single reportable segment.
The exhibit included as Exhibit 99.1 hereto revises the information in the following Items of the 2021 Form 10-K as initially filed in order to reflect, as appropriate, the matters described above: Part II, Item5 (Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities); Part II, Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations); Part II, Item 8 (Financial Statements and Supplementary Data); and Part III, Item 12 (Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters).
