SCOTTSDALE, AZ, Jan. 20, 2026 (GLOBE NEWSWIRE) -- Signing Day Sports, Inc. ("Signing Day Sports" or the "Company") (NYSE:SGN), today announced its continued focus on progressing toward completion of its previously announced business combination with BlockchAIn Digital Infrastructure, Inc. ("BlockchAIn Inc."), One Blockchain LLC ("BlockchAIn LLC"), and certain affiliates (collectively, "BlockchAIn"), a U.S.-based digital infrastructure platform purpose-built to support artificial intelligence ("AI"), high-performance computing ("HPC"), and data-intensive workloads.

Upon completion of the transaction, the combined company is expected to operate as an AI-focused, power-advantaged digital infrastructure platform, anchored by operating data center assets, demonstrated operating cash flow, and a scalable infrastructure footprint located in business-friendly U.S. jurisdictions.

AI-Ready Data Centers with Operating Scale and Expansion Optionality

Building on its existing operating footprint, BlockchAIn's infrastructure roadmap reflects a scalable, modular data center platform designed to support AI, machine learning, and HPC workloads, with significant expansion potential over time:

40 megawatt (MW) operating data center facility in South Carolina, with planned expansion capacity to 50 MW;
Infrastructure expansion expected to support an up to five-fold increase in total data center capacity over time, scaling from the current 40 MW footprint to up to approximately 200 MW, subject to customary approvals, agreements, and execution;
Modular, AI-ready infrastructure architecture designed for high-density compute requirements across AI, machine learning, and HPC workloads; and
AI and HPC data hosting facilities strategy focused on securing low-cost, reliable power, with an increasing emphasis on sustainable and carbon-neutral sources, with minimal consumption requirements.

Low-Cost Power in Strategic, Business-Friendly U.S. Markets

A core differentiator of the BlockchAIn platform is its access to low-cost, reliable power in U.S. states that support digital infrastructure development through favorable regulatory, energy, and business environments. Coupled with the ability to modularly scale projects, BlockchAIn's platform is ideally positioned to monetize transformational growth within the AI market.

As AI workloads become increasingly power-intensive, management believes power economics, reliability, and location will remain critical factors in the deployment of next-generation computing infrastructure.

Established Operating Platform with Demonstrated Cash Flow Generation

In 2024, BlockchAIn LLC generated approximately $22.9 million in revenue and approximately $5.7 million in net income, demonstrating the strength of its operating digital infrastructure platform. Through the first nine months of 2025, the company continued to generate meaningful operating cash flow, supporting day-to-day operations while advancing its AI-ready data center infrastructure.

Management believes these results demonstrate the durability and operating discipline of the platform as demand for AI and HPC infrastructure continues to expand.

Transformational Transaction with a Clear Operating Focus

Following completion of the business combination, Signing Day Sports is expected to become a wholly owned subsidiary of the combined company, while BlockchAIn's digital infrastructure platform is expected to serve as the primary operating foundation going forward.

The Company believes that BlockchAIn's public listing will enable and accelerate future growth, enhance its currency for future acquisitions, and improve access to capital markets. This will support the Company's platform, which is primed for growth through a scalable business model facilitated by existing cash flow, potential leverage, and current development projects.

Jerry Tang, Chief Executive Officer of BlockchAIn, noted, "As we continue to work toward the merger with Signing Day Sports, we are eagerly waiting to enter the public markets to leverage the rapid growth that is occurring in the AI market, specifically infrastructure. AI infrastructure success depends on execution, power access, and operational discipline. Our platform operates in power-advantaged U.S. markets, has generated very strong operating cash flow, and is designed to support high-density computing workloads. We are encouraged by the strong customer interest we are seeing across AI and HPC infrastructure and are confident in the long-term opportunity ahead as our data center capacity is positioned to scale over time. We believe these fundamentals differentiate our infrastructure platform as demand for AI and HPC continues to grow."

"This proposed transaction represents a fundamental evolution for Signing Day Sports," added Daniel Nelson, Chief Executive Officer of Signing Day Sports. "We are confident that we will be combining with a platform that generates real revenue, produces operating cash flow, and owns critical digital infrastructure designed for the next wave of AI-driven demand. These are operating assets located in power-advantaged U.S. markets, built with discipline and execution in mind. We believe these fundamentals will position the combined company to pursue its strategy responsibly and create long-term value for shareholders."

Positioned to Support Long-Term AI Infrastructure Demand

The Company believes the proposed business combination positions the combined platform to support long-term demand for AI-driven computing infrastructure, leveraging operating data centers, disciplined operations, and a scalable development roadmap across strategic U.S. markets.

As previously disclosed, Signing Day Sports entered into a Business Combination Agreement with BlockchAIn and certain affiliates of BlockchAIn on May 27, 2025, as amended on November 10, 2025 and December 21, 2025.
