Spire Global, Inc.

Item 1.01. Entry into a Material Definitive Agreement. On April 8, 2026, Spire Global, Inc. (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with the purchasers named therein (the “Purchasers”), for the private placement (the “Private Placement”) of 5,000,000 shares (the “Shares”) of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), at a purchase price of $14.00 per Share. The aggregate gross proceeds for the Private Placement were $70.0 million, before deducting offering expenses, and the Private Placement closed on April 10, 2026. The Company intends to use the net proceeds from the proposed financing for working capital and general corporate purposes. Pursuant to the Purchase Agreement, the Company agreed that until the date that is 90 days from the effective date (the “Effective Date”) of the registration statement (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “SEC”) for purposes of registering the resale of the Shares, neither the Company nor any subsidiary will issue, enter into any agreement to issue or announce the issuance of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or file a registration statement other than the Registration Statement, subject to certain exceptions. The Company has further agreed not to enter into an agreement involving a Variable Rate Transaction (as defined in the Purchase Agreement) until six months from the Effective Date. In addition, pursuant to lock-up agreements, the Company’s executive officers and directors agreed that until the date that is 90 days from the closing date of the Private Placement, they will not sell or transfer any Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, subject to certain exceptions. The Purchase Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Purchasers, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and other obligations of the parties. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such Purchase Agreement and are made as of specific dates; are solely for the benefit of the parties (except as specifically set forth therein); may be subject to qualifications and limitations agreed upon by the parties in connection with negotiating the terms of the Purchase Agreement, instead of establishing matters as facts; and may be subject to standards of materiality and knowledge applicable to the contracting parties that differ from those applicable to the investors generally. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company. In addition, on April 8, 2026, the Company and the Purchasers entered into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which the Company agreed to file the Registration Statement with the SEC on or before April 23, 2026 for purposes of registering the resale of the Shares, to use its reasonable best efforts to have such Registration Statement declared effective no later than May 8, 2026, and to keep the Registration Statement effective until the date that all registrable securities covered by the Registration Statement (i) have been sold, thereunder or pursuant to Rule 144, or (ii) may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information requirement under Rule 144. The Private Placement is exempt from the registration requirements of the Securities Act pursuant to the exemption for transactions by an issuer not involving any public offering under Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D of the Securities Act and in reliance on similar exemptions under applicable state laws. The Purchasers represented that they were accredited investors within the meaning of Rule 501(a) of Regulation D and were acquiring the Shares as principal for their own accounts and not with a view to or for distributing or reselling the Shares. The Shares were offered without any general solicitation by the Company or its representatives. The Shares sold and issued in the Private Placement will not be registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration with the SEC or an applicable exemption from the registration requirements. The foregoing descriptions of the Purchase Agreement and the Registration Rights Agreement do not purport to be complete and are qualified in their entirety by reference to the Purchase Agreement and the Registration Rights Agreement filed as Exhibits 10.1 and 10.2, respectively, to this Current Report on Form 8-K and incorporated herein by reference.
