Amendment Description As previously disclosed, on April 1, 2021, Finance of America Equity Capital LLC (“FoA”) and Replay Acquisition Corp. (“Replay”), a publicly traded special purpose acquisition company (“SPAC”), completed their previously announced business combination whereby Replay combined with FoA in a series of transactions (collectively, the “Business Combination”) that resulted in Finance of America Companies Inc.
