Capstone Green Energy Files 8‑K, Designates Series A Convertible Preferred Stock

What Happened
Capstone Green Energy Holdings, Inc. filed a Certificate of Designation with the Delaware Secretary of State on March 31, 2026, establishing a new class called Series A Convertible Preferred Stock (the “Preferred Stock”), effective upon filing. The company also issued a press release on March 31, 2026 announcing the closing of a previously announced strategic investment; that release is furnished as Exhibit 99.1 to the 8‑K.

Key Details

• Certificate of Designation for Series A Convertible Preferred Stock was filed with the Delaware Secretary of State on March 31, 2026 and became effective upon filing.
• Terms and conditions of the Preferred Stock were described in the company’s Form 8‑K filed March 31, 2026 and are incorporated by reference; the Certificate of Designation is attached as Exhibit 3.1.
• The company issued a press release dated March 31, 2026 announcing the closing of a strategic investment (Exhibit 99.1).
• The press release is furnished, not “filed,” and therefore is not subject to Section 18 liability or automatically incorporated by reference into future SEC filings unless expressly stated.

Why It Matters
The filing creates a new class of convertible preferred shares that changes the company’s capital structure framework; investors should review the Certificate of Designation and the referenced 8‑K for the specific conversion, voting, and liquidation terms. The announced closing of a strategic investment indicates new financing or a strategic partner relationship—details are in the furnished press release (Exhibit 99.1). Retail investors should read the attached documents to assess impacts on dilution, rights, and governance.
