Exhibit 99.1

XCF Global Provides Update on

Ongoing Capital Raise and Merger Discussions

Houston, TX – March 10, 2026 - XCF Global, Inc. (“XCF”) (Nasdaq: SAFX) a leading innovator in decarbonizing the aviation industry through Sustainable Aviation Fuel (“SAF”) today announced that, at a Special Meeting of its Stockholders held on March 6, 2026, its stockholders approved the issuance of 19.99% or more of the Company’s issued and outstanding Common Stock as of January 26, 2026 pursuant to a private placement offering of shares of Common Stock to a single investor in accordance with Nasdaq Listing Rules 5635(d) and 5635(b).

As XCF previously reported, on January 26, 2026, XCF entered into a binding term sheet with Southern Energy Renewables, Inc., a Louisiana corporation (“Southern”), DevvStream Corp., an Alberta corporation (“DEVS”), and EEME Energy SPV I LLC (“EEME”), which sets forth the principal terms and conditions of a proposed business combination among such parties. The Term Sheet also contemplates that XCF will invest $10 million to convert and build out its New Rise Renewables Reno facility for SAF production and blending and related corporate purposes (the “Plant Conversion”), to be funded through the sale by XCF to EEME of $10 million of Common Stock; provided that in no event would XCF issue to EEME, nor would EEME (i) acquire more than 41,639,170 shares of XCF’s common stock pursuant to the Term Sheet or (ii) acquire or to otherwise become, directly or indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended and the rules and regulations promulgated thereunder) of a number of shares of Common Stock in excess of 19.99% of the issued and outstanding shares of Common Stock as of the date hereof until such time as XCF has obtain stockholder approval for such issuance (the “Share Cap”).

As part of the planned Plant Conversion, XCF has initiated upgrades to the New Rise Renewables Reno facility, including the procurement of a new hydrotreating catalyst. This technology will enable the facility to convert a broad range of renewable feedstocks into high-quality neat sustainable aviation fuel, SAF, that meets ASTM D7566 specifications. The upgraded hydrotreating system will utilize Axens’ Vegan ® technology, a proven platform designed for flexible high -performance renewable fuel production. XCF’s stockholder approval obtained at the March 6, 2026 Special Meeting of Stockholders removes the Share Cap and allows EEME to acquire the balance of the shares it committed to purchase pursuant to the Term Sheet. Prior to today, EEME had acquired 38,000,000 shares of XCF Common Stock pursuant to the Term Sheet for a total of $3,800,000. XCF anticipates that EEME will acquire remaining 62,000,000 shares under the Term Sheet, for a total of $6,200,000, in two equal tranches, with half being funded during the week of March 7, 2026, and the other half being funded during the week of March 31, 2026.

“We are pleased to have achieved this milestone,” stated Chris Cooper, XCF’s Chief Executive Officer. “With work on the Plant Conversion already underway and our hydrotreating catalyst now in production with Axens, we believe we are well positioned to advance the upgrade of our New Rise Renewables Reno facility, even as the parties to the contemplated business combination continue to undertake due diligence and negotiate the definitive agreements related to the proposed business combination.”

The proposed business combination remains subject to negotiation of definitive agreements and required approvals. EEME’s obligation to acquire such shares is independent of the remainder of the proposed Transaction contemplated by the Term Sheet.

The proposed business combination, upon completion, is expected to provide a meaningful advancement in XCF’s ability to help airlines and their customers reduce emissions associated with air travel. By combining multiple SAF production pathways with integrated environmental attribute monetization, it is anticipated that the combined entity will be in an enhanced position to access lower-carbon non-fossil-based solutions, meet regulatory requirements, and accelerate the availability of SAF options for the aviation sector.

If the proposed transaction is completed, it is anticipated that XCF would become the parent entity of the combined platform, creating the first publicly traded SAF company in the United States capable of providing multiple non-fossil-based SAF production pathways alongside high integrity environmental attributes. In addition to HEFA and biomass-to-SAF pathways, the combined platform is expected to incorporate an emerging eSAF pathway through e-methanol-to-jet technology enabled by Southern. This structure is expected to position XCF to serve a broader range of customers by matching regional feedstock availability, market incentives, and emissions reduction requirements with the most efficient SAF pathway and associated high - integrity environmental attributes.

“As demand for sustainable aviation fuel accelerates globally, the ability to deploy multiple technology pathways under one company creates meaningful flexibility and commercial optionality,” said Chris Cooper, XCF’s Chief Executive Officer. “Airlines and corporate customers increasingly require both physical SAF and verified environmental attributes or SAF certificates to meet their decarbonization and reporting obligations. The combined platform is designed to make SAF more accessible, scalable, and better aligned with the diverse needs of customers across regions and feedstock markets.”

There can be no assurance that any definitive agreements will be entered into or that the proposed transaction will be consummated on the terms described herein or at all.
