GRAHAM CORP 8-K

What Happened

• On June 18, 2026, Graham Corporation (GHM) posted the slide deck that will accompany its presentation at the company’s 2026 Investor Day to the investor relations section of its website. The company furnished the slide presentation as Exhibit 99.1 to a Form 8-K under Item 7.01 (Regulation FD Disclosure) filed the same day.

Key Details

• Date of posting and filing: June 18, 2026.
• Disclosure type: Item 7.01 — Regulation FD Disclosure (slides made broadly available).
• Exhibit furnished: Slide Presentation (Exhibit 99.1) accompanying the Investor Day presentation.
• The Form 8-K also includes the Inline XBRL cover page (Exhibit 104).

Why It Matters

• The filing makes the Investor Day presentation widely available to all investors at the same time, which helps ensure fair disclosure of any material information presented.
• Investors should review the posted slides for management’s updates, strategy, or any new operational or financial information; the 8-K itself does not report earnings or new financial statements.
