Cove Kaz and Skyline Mutually Terminate Previously Announced Business Combination Agreement New Equity Funding Commitment of $32 Million at Valuation of Approximately $2 Billion NEW YORK & ASTANA, Kazakhstan--( BUSINESS WIRE )--Cove Kaz Capital Group LLC (“Cove Kaz” or “the Company”), a U.S.-based company engaged in the development of tungsten and other critical mineral resources in Kazakhstan, today announced that it and Skyline Builders Group Holding Limited (Nasdaq: KAZR) (“Skyline”) have mutually agreed to terminate their previously announced business combination agreement, originally announced on April 30, 2026, under which Skyline and Cove Kaz had proposed to combine. Under the terms of the termination agreement, Skyline has agreed to change its ticker symbol and release the “KAZR” symbol within fifteen days. The Company has also secured a new capital commitment from American Ventures, LLC of $32.0 million for four million shares, at $8.00 per share, implying an equity value for the Company of $1.97 billion and representing approximately 1.62% of the Company’s shares outstanding post-transaction. The closing of this equity funding commitment is subject to customary closing conditions, and there can be no assurance that it will be completed on the anticipated terms or at all. Following this round of funding, approximately 70% of the Company’s shares will be held by the Company’s existing members and Kaz Resources, LLC, and approximately 26% will be held by Skyline. Commenting on these developments, Executive Chairman of Cove Kaz Pini Althaus said: “We appreciate the collaborative work with the Skyline team throughout this process. We believe terminating the business combination agreement was in the best interests of both companies. The new capital commitment represents a 76% uplift in our valuation compared with the prior agreement with Skyline, demonstrating investor recognition of the progress we are making towards developing this generational tungsten project in Kazakhstan and the structural need for new primary tungsten production to the global economy. The additional capital will fund engineering and construction-related work to shorten our time to production.” Mr. Althaus continued, “Increasing demand from defense, technology, and advanced manufacturing, coupled with Chinese export controls and constrained Ex-China supply, drove benchmark tungsten (APT) prices to record highs earlier this year. According to AsiaMetals, the APT price in warehouse in Rotterdam remains around $280,000 per metric tonne, compared with $33,500/t in 2024 and $50,000/mt in 2025.” “The tungsten market commands the development of Northern Katpar and Upper Kairakty, a tier-one generational tungsten project with an anticipated mine life exceeding fifty years. In the last decade, the United States has no domestic tungsten mine production and new Pentagon procurement restrictions on Chinese-origin tungsten take effect in January 2027,” Mr. Althaus noted. The Company also plans to convert to a Delaware corporation, combine with certain other Cove Capital LLC-affiliate assets in Kazakhstan subject to Kazakhstan government and other regulatory approvals, and change its name to Kaz Resources, Inc.
