Signing Day Sports Highlights BlockchAIn's Modular AI Data Center Strategy and Strategic Electrical Infrastructure Collaboration with PDM

Designed to Reduce Build Times, Lower Capital Costs, and Accelerate Revenue Generation

Scottsdale, AZ, March 09, 2026 (GLOBE NEWSWIRE) -- Signing Day Sports, Inc. (“Signing Day Sports” or the “Company”) (NYSE American: SGN), in connection with the Company’s previously announced proposed business combination with One Blockchain LLC (“BlockchAIn LLC”), BlockchAIn Digital Infrastructure, Inc. (“BlockchAIn Inc.” and together with BlockchAIn LLC, “BlockchAIn”), and certain affiliates of BlockchAIn, today provided additional detail regarding BlockchAIn’s infrastructure development strategy as it prepares to scale a U.S.-based platform designed to support the rapidly expanding demand for artificial intelligence (“AI”) and high-performance computing (“HPC”) infrastructure.

The proposed business combination is expected to close on March 2026, subject to certain closing conditions, including stockholder approval and applicable regulatory and listing approvals. Upon consummation of the transaction, the shares of BlockchAIn Inc. are expected to trade on the NYSE American under the ticker symbol “AIB.”

BlockchAIn’s development strategy focuses on converting strategically located power resources into AI and high‑performance computing infrastructure through a modular deployment architecture. By combining access to low‑cost, reliable power with standardized prefabricated data center modules and secured electrical infrastructure supply, the platform is designed to rapidly convert power capacity into revenue‑generating digital infrastructure assets

BlockchAIn’s management believes this power‑to‑AI infrastructure model allows BlockchAIn to accelerate development timelines, reduce capital intensity, and scale capacity across multiple sites in response to growing enterprise and cloud demand for AI compute.

To support the long‑term scale of its platform, on March 5, 2026, BlockchAIn entered into a strategic collaboration with Power and Data Management LLC (“PDM”), a manufacturer of heavy electrical infrastructure equipment serving data centers, utilities, and other mission‑critical industries.

PDM designs and manufactures utility‑grade electrical infrastructure including pad mount, dry‑type, and substation transformers, as well as high‑voltage circuit breakers and gas‑insulated switchgear, which form the backbone of power distribution systems for large‑scale digital infrastructure.  Through this collaboration, BlockchAIn expects PDM to support its infrastructure rollout by providing electrical systems—including transformers, switchgear, and power distribution equipment—which BlockchAIn believes will support a potential development pipeline of approximately 5–6 gigawatts (GWs) of planned data center capacity across multiple sites.

PDM’s design and manufacturing capabilities allow the company to deliver built‑to‑spec transformers with significantly shorter lead times than typical industry supply chains, helping developers accelerate project timelines and mitigate supply‑chain constraints that have slowed large data center deployments globally.  Their exclusive global partnerships with manufacturers enable them to deliver built-to-spec transformers in as little as 9 weeks, power substations in 5-10 months, circuit breakers in 5-8 months and gas-insulated switchgear in 8 months. PDM leverages long-term relationships and leadership experience from careers at GE and Emerson Electric to deliver efficient, reliable power distribution solutions.  In addition, BlockchAIn’s management believes that PDM’s U.S.-based operations in Salt Lake City strengthen BlockchAIn’s ability to meet requirements for “Made in USA with imported and domestic parts” which enhance supply-chain reliability and economic impact at home.  

A core component of the BlockchAIn platform is its access to low‑cost, reliable power in U.S. jurisdictions that support digital infrastructure development through favorable regulatory frameworks, energy markets, and business environments.

By combining strategic power access with modular infrastructure deployment and reliable electrical equipment supply, BlockchAIn aims to convert power and land into revenue‑generating AI infrastructure with greater speed and capital efficiency than traditional data center development models.

BlockchAIn’s management believes this integrated approach positions the platform to support the accelerating demand for AI compute capacity while maintaining capital discipline and operational flexibility as the company scales.

“Modular deployment materially improves both the economics and execution profile of data center development,” said Jerry Tang, Chief Executive Officer of BlockchAIn LLC. “This approach is particularly well suited for high‑density AI and HPC workloads, where speed of deployment, power efficiency, and scalability are increasingly critical. Our access to low‑cost, reliable power in strategic U.S. markets, combined with our collaboration with PDM to provide critical electrical infrastructure that we believe will support a development pipeline of approximately 5–6 GWs of power capacity, positions our platform to scale efficiently and respond to accelerating demand for AI infrastructure.”

“Access to critical electrical infrastructure is one of the most important factors in scaling large‑scale data center capacity today,” said Eyal Rozen, Chief Operating Officer of BlockchAIn LLC. “We anticipate that our collaboration with PDM will strengthen our supply chain for transformers and other key electrical equipment, helping us reduce development risk and accelerate deployment across multiple sites. Combined with our modular architecture strategy, this collaboration may enable us to bring capacity online faster and convert power and land into revenue‑generating infrastructure as demand for AI compute continues to grow.”

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 (and as may be amended from time to time, the “Business Combination Agreement”).  Pursuant to the Business Combination Agreement, Signing Day Sports and BlockchAIn LLC will become wholly-owned subsidiaries of BlockchAIn Inc. The Company expects the closing of the transaction will take place in March 2026, subject to certain closing conditions, including stockholder approval and NYSE American listing approval. BlockchAIn Inc. filed the Registration Statement in connection with the proposed transaction on December 1, 2025, as amended on December 23, 2025, January 21, 2026, January 22, 2026, and January 30, 2026 (as amended from time to time, the “Registration Statement”), which was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on January 30, 2026.

BlockchAIn LLC is a developer and operator of digital infrastructure focused on HPC and AI hosting. BlockchAIn LLC has planned AI data center expansions with favorable economics for activation in 2026 and 2027. BlockchAIn LLC operations are currently centered around its existing 40 MW data center facility in South Carolina. In 2024, this facility generated approximately $22.9 million in revenue and approximately $5.7 million in net income. BlockchAIn LLC’s mission is to become a leader in creating and operating scalable sustainable power and data infrastructure purpose-built for AI hosting, AI workloads, HPC, and accelerated compute applications.
