| Amendment Description | On May 3, 2022, Primis Financial Corp. (the “Company”) filed with the Securities and Exchange Commission (the “SEC”) a Current Report on Form 8-K (the “Original Report”), which disclosed the entry by the Company’s wholly-owned subsidiary, Primis Bank, into a Stock Purchase Agreement (the “Purchase Agreement”) with Community First Bank, Inc. (“Seller”) and SeaTrust Mortgage Company (“SeaTrust”), pursuant to which the Bank will purchase 100% of the outstanding capital stock of SeaTrust from Seller (the “Acquisition”). The Original Report included a copy of the Purchase Agreement as an exhibit, but inadvertently listed the Purchase Agreement as Exhibit 1.01, rather than Exhibit 10.01. The Company is filing this Amendment No.1 on Form 8-K/A (this “Amendment”) solely to assign the correct reference number to the copy of the Purchase Agreement that was filed with the Original Report. This Amendment does not amend or update any other information contained in the Original Report. This Amendment No. 1 should be read in conjunction with the Original Report. |
