Atlantic Union Bankshares Corp 8-K

What Happened

• On July 27, 2026, Atlantic Union Bankshares Corporation filed a preliminary prospectus supplement to its August 6, 2024 prospectus (Form S-3ASR, File No. 333-281290) announcing a proposed offering of a newly issued series of fixed-to-floating rate subordinated notes due 2036 (the “Notes”).
• The company made an investor presentation available to management for meetings with potential purchasers; that presentation is filed as Exhibit 99.1 to the Form 8-K.

Key Details

• Filing date: July 27, 2026; underlying prospectus date: August 6, 2024 (Form S-3ASR).
• Security: Fixed-to-Floating Rate Subordinated Notes due 2036.
• Document included: Investor Presentation filed as Exhibit 99.1.
• The filing is a preliminary prospectus supplement — specific offering terms (size, interest rate, pricing, and closing date) are not disclosed in the 8-K.

Why It Matters

• This 8-K signals Atlantic Union’s intent to raise capital through subordinated debt, which could affect the company’s capital structure and interest obligations once terms are finalized.
• For investors, the filing is a material corporate financing update but not a completed transaction; watch for subsequent filings that disclose the offering’s size, pricing and final terms.
