Astrana Health Files Regulation FD Update; New Investor Presentation

What Happened

• Astrana Health, Inc. filed a Form 8-K on September 15, 2026 to disclose an updated corporate presentation the company will use at conferences and investor meetings. The slides are attached as Exhibit 99.1 to the filing and are being furnished under Regulation FD.

Key Details

• Date of disclosure: September 15, 2026.
• Exhibit provided: Investor Presentation (Exhibit 99.1).
• The presentation materials are furnished (not “filed”) and the company does not undertake to update them.
• The filing includes the standard cover page interactive XBRL file (Exhibit 104) and reiterates that statements may be forward-looking and subject to risks described in Astrana’s SEC filings.

Why It Matters

• For investors, the update provides Astrana’s current public messaging, strategy highlights, and investor materials used in outreach. Because the slides are furnished rather than filed, they are not subject to Section 18 liability and are not automatically incorporated into future SEC filings. Investors should review the presentation along with Astrana’s filings (Form 10-K/10-Q) for full context and note that any forward-looking statements in the materials are subject to the risks outlined in those filings.
