DIVERSIFIED HEALTHCARE TRUST 8-K

What Happened

• Diversified Healthcare Trust (DHC) announced on June 1, 2026 that it posted an investor presentation to its website. A copy of the presentation is attached to the Form 8-K as Exhibit 99.1 and was furnished under Item 7.01 (Regulation FD Disclosure).

Key Details

• Date of disclosure: June 1, 2026.
• Exhibit included: 99.1 — Investor Presentation (furnished, not filed).
• SEC filing items: Item 7.01 (Regulation FD Disclosure) and Item 9.01 (exhibits); Exhibit 104 (Cover Page Interactive Data File) embedded in the Inline XBRL.

Why It Matters

• The presentation is public and available on DHC’s investor website, so investors can review any updated corporate, operational, or strategic information the company chose to share. Because the material was furnished under Reg FD, it reflects a public disclosure intended for all investors simultaneously. Note that furnished exhibits are generally not “filed” for purposes of liability or incorporation by reference in other SEC filings.
