Key Details

• Filing date: May 6, 2026 (Form 8-K, Item 7.01 - Regulation FD disclosure).
• Presentation exhibit: Exhibit 99.1 furnished with the 8-K and to be posted on www.twindisc.com.

Why It Matters

• Furnishing an investor presentation under Regulation FD informs the market about what management will present to investors and analysts; the slide deck may contain supplemental metrics and performance context not in formal earnings filings. Investors should review the presentation on the company website and be aware the deck may include non-GAAP measures and is not a replacement for the company’s SEC filings or audited GAAP results.
