CoreAI Holdings Reports Record 59% Revenue Growth and Strategic AI Expansion

MIAMI, FL — May 18, 2026 — Core AI Holdings, Inc. (Nasdaq: CHAI) (“Core AI” or the “Company”), a global AI infrastructure and technology platform today announced financial results for the fiscal year ended December 31, 2025, highlighting a transformational year marked by significant revenue growth, divestment of underperforming legacy business, and the launch of the Company’s next phase as an AI infrastructure-focused enterprise.

Revenue from continuing operations increased 58.6% year-over-year to $55.2 million in 2025, compared to $34.8 million in 2024, reflecting expanded operational scale and contributions from the Company’s evolving AI and digital platform initiatives.

Gross profit from continuing operations was a loss of approximately $(302,662), reflecting restructuring activities, transition-related costs, operational realignment, and the Company’s sharper focus on AI infrastructure and next-generation technology opportunities

Key2025 Financial Highlights

During 2025, the Company undertook substantial strategic and operational restructuring initiatives designed to reposition the business toward higher-growth AI opportunities. These transformation activities impacted short-term profitability metrics, including gross profit, as management prioritized long-term platform development and operational streamlining.

“Our 2025 fiscal year represented a foundational transition for Core AI,” said Aitan Zacharin, Chief Executive Officer of Core AI Holdings. “We significantly expanded revenue, streamlined our strategic focus, and positioned the Company to pursue opportunities at the intersection of AI infrastructure and next-generation digital platforms. While we incurred substantial one-time restructuring and transaction-related charges associated with this transformation, we believe these actions establish the framework for long-term shareholder value creation.”

Management noted that 2025 results included substantial non-cash and non-recurring items associated with discontinued Siyata PTT operations, transaction expenses, restructuring activities, financing costs, and strategic repositioning efforts undertaken during the year. Excluding these transformational items, management believes the Company is increasingly aligned with long-term opportunities in AI infrastructure, compute capacity, and digital ecosystem enablement. We executed a major strategic repositioning of the business, expanded revenue significantly, and established the foundation for our long-term AI infrastructure strategy.

“AI infrastructure is rapidly becoming one of the defining investment themes of this decade,” Zacharin added. “We believe Core AI is strategically positioned to capitalize on this market evolution through disciplined execution, differentiated technology, strategic partnerships, and targeted growth initiatives.”

The Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2025 was filed with the U.S. Securities and Exchange Commission on May 15, 2026 and is available on the SEC’s website.
