Investment reflects 10.5% equity interest in Operating Aerospace-Spec LNG Producer Positioned for the U.S. Space Launch Buildout Eagle LNG produces high-methane, aerospace-specification LNG required by the next generation of American reusable launch vehicles Investment is being made concurrently with, and at the same value per unit as, a $10 million commitment by an affiliate of The Energy & Minerals Group (“EMG”). Funds managed by EMG are Eagle LNG’s controlling sponsor and an existing investor in the business SALT LAKE CITY, Aug. 31, 2026 (GLOBE NEWSWIRE) -- Datacentrex, Inc. (“Datacentrex” or the “Company”) (Nasdaq: DTCX) today announced that it has entered into a Common Unit Purchase Agreement and invested $30 million in ELNG Equity LLC (“ELNG”), the equity holding company of Eagle LNG Partners LLC (“Eagle LNG”), acquiring $30 million of Class A Common Units. Eagle LNG is a vertically integrated producer of liquefied natural gas and a qualified supplier of the aerospace-specification liquid methane used to fuel next-generation American launch vehicles. An Operating Business, Not a Development Project Eagle LNG has been producing and delivering LNG since 2017 and serves a contracted customer base across space propulsion, marine bunkering, island utility and industrial end-markets under long-term take-or-pay supply agreements with a weighted average tenor of approximately 15 years. Since 2018 it has completed more than 700 LNG bunkering operations, both ship-to-shore and ship-to-ship, without incident. “We are focused on companies producing real revenue in ultra-high-growth sectors, and we intend to be at the forefront of them,” said Parker Scott, Chief Executive Officer of Datacentrex. “Eagle LNG is not a concept. It has been producing and delivering LNG since 2017 and it is already under contract with a leading space propulsion customer. The United States is setting out to multiply its launch cadence several times over this decade, and every one of those vehicles has to be fueled. We would rather own a position in the supply chain underneath that growth than try to pick which vehicle wins.” About Datacentrex, Inc.

Shares of Combined Company, to Be Renamed XTEND AI Robotics, Expected to Begin Trading on the NYSE Under the Ticker Symbol “XTND” on September 4, 2026 TAMPA, Fla., Aug. 31, 2026 (GLOBE NEWSWIRE) -- JFB Construction Holdings (Nasdaq: JFB) and XTEND, a leader in software systems and artificial intelligence-powered robotics, announced today that the previously announced business combination between JFB and XTEND Reality Expansion Ltd. remains on track to close on September 3, 2026. Upon closing, the combined company will be renamed XTEND AI Robotics, Inc., and its common stock is expected to begin trading on the New York Stock Exchange (“NYSE”) under the ticker symbol “XTND” on September 4, 2026. JFB’s Class A common stock is expected to cease trading on the Nasdaq Stock Market after the close of trading hours on September 3, 2026. The anticipated closing follows the U.S. Securities and Exchange Commission’s (“SEC”) declaration of effectiveness, on August 11, 2026, of the Form S-4 registration statement filed in connection with the proposed business combination, clearing a key regulatory milestone ahead of closing. The final information statement/prospectus was mailed to JFB stockholders of record as of August 11, 2026. The business combination will be completed through a series of mergers pursuant to the Agreement and Plan of Merger, dated as of February 13, 2026, as amended on March 21, 2026 and as further amended on July 16, 2026 (the “merger agreement”), by and among JFB, XTEND, XTEND AI Robotics, and the applicable merger subsidiaries. Under the terms of the merger agreement, XTEND Reality Expansion Ltd. will become a direct, wholly owned subsidiary of XTEND AI Robotics, and JFB will become a direct, wholly owned subsidiary of XTEND AI Robotics. In the all-stock transaction, each outstanding share of JFB common stock is, subject to the following sentence, expected to be converted into the right to receive one share of XTEND AI Robotics common stock, and each outstanding XTEND ordinary share will be converted into the right to receive approximately 1.36 shares of XTEND AI Robotics common stock, in each case subject to the terms of the merger agreement. To satisfy the minimum listing price required by the NYSE initial listing standards, in the event that the closing stock price of JFB’s Class A common stock is less than $4.00 on September 3, 2026, the last day on which JFB’s Class A common stock is expected to trade on Nasdaq, XTEND and JFB have agreed to amend the merger agreement to modify the exchange ratio such that each outstanding share of JFB common stock will instead receive one-half of a share of XTEND AI Robotics common stock, and each outstanding XTEND ordinary share will be converted into the right to receive approximately .68 shares of XTEND AI Robotics common stock. Under either exchange ratio, former JFB and former XTEND shareholders will beneficially own the same proportion of XTEND AI Robotics. “As we work through the final steps toward closing our merger with JFB, we remain on track to close on September 3, 2026,” said Aviv Shapira, Co-Founder and CEO of XTEND. “With our shares expected to begin trading on the NYSE under the ticker ‘XTND’ shortly after, we are entering the next chapter of XTEND’s growth ready to scale our AI-powered robotics platform for defense, law enforcement, and security customers around the world.” XTEND’s software-enabled robotic systems are designed to extend the reach and effectiveness of defense and security operators while reducing human exposure in high-risk environments. The company’s platform combines advanced robotic hardware with intuitive control, mission management, and autonomous capabilities designed to support rapid deployment across diverse operational scenarios.
