SERA PROGNOSTICS, INC. 8-K

What Happened
Sera Prognostics, Inc. announced its financial results for the fourth quarter and fiscal year ended December 31, 2025 via a press release dated March 18, 2026. The company filed a Current Report on Form 8-K (Item 2.02) to furnish that press release and provide business highlights; the full press release is included as Exhibit 99.1 to the filing.

Key Details

• Date of filing and press release: March 18, 2026.
• Reporting period: fourth quarter and fiscal year ended December 31, 2025.
• Press release furnished as Exhibit 99.1 to the Form 8-K.
• Form 8-K signed by CFO Austin Aerts; the filing states the furnished press release is not “filed” for purposes of Section 18 of the Exchange Act and is not incorporated by reference except as required by law.

Why It Matters
This 8-K signals Sera’s timely disclosure of its quarterly and annual earnings and business highlights—investors should read the attached press release (Exhibit 99.1) for specific financial metrics such as revenue, earnings, and operating results. Because the press release is furnished (not “filed”), it has limited incorporation-by-reference consequences under securities law; nevertheless, the content is the company’s official public earnings disclosure for Q4 and FY2025.
