Insights

Securities Analyst

TL;DR: Private placement issues non-expiring pre-funded warrants for 5.23M shares at $16.249, with registration rights and typical risk disclosures.

The transaction supplies immediate financing via sale of pre-funded warrants, which are often used to enable investors to avoid ownership limits while allowing near-immediate conversion into common stock for a nominal exercise price. The company committed to timely registration for resale, which reduces secondary-market liquidity restrictions for investors once effective. The filing highlights programs MZE829 and MZE782 in forward-looking language, indicating ongoing development activities tied to financing needs. Materiality is signaled by an 8-K disclosure and the inclusion of transaction documents as exhibits.

Corporate Governance Expert

TL;DR: The company followed standard disclosure and investor protections: accredited-investor limitations, registration rights, and forward-looking disclaimers.

The document shows customary investor representations (accredited status and investment intent) and a Registration Rights Agreement requiring prompt filing and efforts to obtain effectiveness. Exhibited transaction documents and press releases provide transparency. The non-expiring nature of the pre-funded warrants and the extremely low exercise price shift dilution timing risk to the company once warrants convert, so governance should ensure shareholder communication about potential capitalization changes following registration effectiveness.

Item 1.01. Entry into a Material Definitive Agreement.

Securities Purchase Agreement

On September 10, 2025, Maze Therapeutics, Inc., a Delaware corporation (the “Company”), entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain institutional and accredited investors (the “Investors”), pursuant to which the Company agreed to sell and issue to the Investors in a private placement (the “Private Placement”) an aggregate of (i) 4,000,002 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at a purchase price of $16.25 per share and (ii) in lieu of shares of Common Stock for certain Investors, pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to an aggregate of 5,231,090 shares of Common Stock (the “Warrant Shares” and, together with the Shares and the Pre-Funded Warrants, the “Securities”) at a purchase price of $16.249 per Pre-Funded Warrant. Each Pre-Funded Warrant has an exercise price of $0.001 per Warrant Share. The Pre-Funded Warrants are exercisable at any time after their original issuance and will not expire.

The Private Placement is anticipated to close on or about September 12, 2025, subject to the satisfaction of customary closing conditions. The Company anticipates receiving gross proceeds from the Private Placement of approximately $150.0 million, before deducting placement agent fees and other expenses. The Company intends to use the proceeds from the private placement, together with its existing cash, cash equivalents and short-term investments, to advance the development of MZE829 in patients with APOL1-mediated kidney disease, initiate Phase 2 clinical trials of MZE782 in both phenylketonuria and chronic kidney disease, continue progress on research and discovery programs, further the development of its Compass platform, and for working capital and other general corporate purposes.

The Pre-Funded Warrants to be issued in the Private Placement will provide that the holder of the Pre-Funded Warrants will not have the right to exercise any portion of its Pre-Funded Warrants if such holder, together with its affiliates, would beneficially own in excess of 4.99% or 9.99%, at the holder’s election, of the number of shares of the Company’s Common Stock outstanding immediately after giving effect to such exercise.

The foregoing descriptions of the Securities Purchase Agreement and Pre-Funded Warrants do not purport to be complete and are qualified in their entirety by reference to the full text of the Securities Purchase Agreement and the Pre-Funded Warrants, which are filed as Exhibits 10.1 and 4.1, respectively, to this Current Report on Form 8-K and are incorporated by reference herein.

Registration Rights Agreement

In connection with the Private Placement, the Company and the Investors also entered into a Registration Rights Agreement, dated as of September 10, 2025 (the “Registration Rights Agreement”), providing for the registration for resale of the Shares and the Warrant Shares. The Company has agreed to prepare and file a registration statement (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) promptly, and in any event within 60 days of the closing of the Private Placement, and to use its reasonable best efforts to have the Registration Statement declared effective within 75 days following the initial filing date of the Registration Statement.

The Company has granted the Investors customary indemnification rights in connection with the Registration Rights Agreement. The Investors have also granted the Company customary indemnification rights in connection with the Registration Statement.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement, which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated by reference herein.

The Securities have not been 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 Investors represented that they are accredited investors, as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and that they are acquiring the Securities for investment purposes only and not with a view to any resale, distribution or other disposition of the Securities in violation of the U.S. federal securities laws.
