The company files an amendment to a prior current report related to its merger with Legacy Republic. It adds unaudited condensed consolidated financial statements for Legacy Republic, unaudited pro forma condensed combined financial information reflecting the merger, and files its certificate of incorporation, which had been inadvertently omitted from the earlier report.

No. The amendment states that it is being filed solely to amend and supplement the financial information section and to add the certificate of incorporation as an exhibit. It makes no other amendments to the earlier report and does not provide an update on developments at the company or its subsidiaries after that earlier filing.

The amendment incorporates unaudited condensed consolidated financial statements of Legacy Republic as of September 30, 2025 and December 31, 2024 and for the nine months ended September 30, 2025 and 2024. These are presented as Exhibit 99.1 and are referenced as part of the company’s disclosure.

Exhibit 99.3 contains unaudited pro forma condensed combined financial information and notes as of and for the nine months ended September 30, 2025 and for the year ended December 31, 2024. This information gives effect to the merger and related transactions and is described as being for informational purposes only, not as indicative of future results or exact historical outcomes.

The company explains that it is filing its certificate of incorporation as Exhibit 3.1 because it was inadvertently omitted from a prior exhibit in the original report. The amendment is intended to correct that omission so that the company’s governing document is properly included in the exhibit list.
