Maplebear Inc.

Item 3.02 Unregistered Sales of Equity Securities. On September 21, 2026, Maplebear Inc. (the “Company”) received notice from the holder (the “Holder”) of the Company’s Series A Convertible Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”), to convert all 5,833,333 shares of such holder’s Series A Preferred Stock into shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock,” and such transaction, the “Conversion”). In accordance with the Certificate of Designation of Series A Convertible Preferred Stock (the “Certificate of Designation”) to the Company’s Amended and Restated Certificate of Incorporation (the “Restated Certificate”), the Company issued 5,833,333 shares of Common Stock to the Holder upon the Conversion, which shares of Common Stock may not be transferred or otherwise disposed of for a period of 35 days after issuance. The issuance of the Common Stock is exempt from registration under Section 3(a)(9) under the Securities Act of 1933, as amended, as the Series A Preferred Stock was exchanged for Common Stock by an existing security holder and no commission or other remuneration was paid. Following the Conversion, no shares of Series A Preferred Stock remain outstanding.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year. On September 24, 2026, the Company filed a Certificate of Elimination (the “Certificate of Elimination”) with the Secretary of State of the State of Delaware eliminating from the Restated Certificate all provisions of the Certificate of Designation. Such shares previously designated Series A Preferred Stock have been returned to the authorized but undesignated shares of the Company’s preferred stock. The foregoing summary of the Certificate of Elimination is qualified in its entirety by reference to the full text of the Certificate of Elimination, a copy of which is attached hereto as Exhibit 3.1 and incorporated herein by reference.
