DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (the “Post-Effective Amendments”) (i) relate to the following Registration Statements on Form S-1 (each, a “Registration Statement”, and collectively, the “Registration Statements”) of DevvStream Legacy Corp., a Delaware corporation (the “Registrant”), which were previously filed by the Registrant with the U.S. Securities and Exchange Commission (the “Commission”) and (ii) are being filed to deregister all shares of the Registrant’s common shares, no par value (the “Shares”) that remain unsold or otherwise unissued as of the date hereof under each such Registration Statement.

  1.
Registration Statement No. 333-285728, registering the resale of up to 114,968,270 common shares (pre-split) held by the selling stockholder, which was filed with the Securities and Exchange Commission (“SEC”) on March 12, 2025 and amended on November 10, 2025.

 
2.
Registration Statement No. 333-286070, registering the resale of up to 27,133,026 common shares (pre-split) held by the selling stockholders, which was filed with the SEC on March 25, 2025 and amended on June 13, 2025, June 27, 2025, July 1, 2025, July 2, 2025 and November 10, 2025.
 
On April 13, 2026, the Registrant (f/k/a DevvStream Corp.) entered into a Business Combination Agreement with XCF Global, Inc., a Delaware corporation (“XCF”), Southern Energy Renewables Inc., Southern Merger Sub Inc. and DevvStream Merger Sub, which was amended on September 14, 2026 (as amended, the “BCA”). On October 16, 2026, under the BCA, DevvStream Merger Sub merged with and into the Registrant, and the Registrant survived as a wholly owned subsidiary of XCF (the “Merger”). In the Merger, each Share was converted into the right to receive 1.1919 shares of XCF common stock (“XCF Common Stock”).
 
As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statements. In accordance with an undertaking made by the Registrant in each of the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for resale that remain unsold at the termination of the offerings, the Registrant hereby removes from registration all such securities registered under the Registration Statements that remain unsold as of the date hereof and terminates the effectiveness of the Registration Statements. As a result of this deregistration and upon the effectiveness of these Post-Effective Amendments, no Shares will remain registered pursuant to the Registration Statements.
