1ST SOURCE CORP 8-K

What Happened
1st Source Corporation (SRCE) filed a Form 8-K on January 30, 2026 under Item 7.01 (Regulation FD Disclosure) stating that its executive officers intend to use an investor presentation in one or more meetings with investors and analysts. The presentation is included as Exhibit 99.1 to the filing.

Key Details

• Filing date: January 30, 2026; Form 8-K signed by Brett A. Bauer, Treasurer and Chief Financial Officer (Principal Accounting Officer).
• Item disclosed: 7.01 — Regulation FD Disclosure (executives will use the attached investor presentation in meetings).
• Exhibit included: Exhibit 99.1 — 1st Source Corporation Investor Presentation.
• Administrative note: Exhibit 99.1 and related Inline XBRL cover page (Exhibit 104) are furnished and explicitly “not deemed filed” under the Securities Exchange Act.

Why It Matters
This is a routine Reg FD disclosure indicating 1st Source is sharing an investor presentation with market participants. For investors, the attached presentation is the primary source to review for management commentary, strategy updates, or summarized financial highlights the company intends to present. Because the exhibit is furnished (not “filed”), investors should review the presentation itself for details rather than relying solely on the 8-K cover notice.
