AlphaTON Capital Advances Strategic Roadmap with Revenue Generation from Confidential Compute AI Infrastructure

AlphaTON Raised Net $44 Million in Capital and is Generating Revenue with AI Infrastructure from Telegram's Cocoon AI

New York, NY, Jan. 28, 2026 (GLOBE NEWSWIRE) -- AlphaTON Capital Corp. (Nasdaq: ATON) ("AlphaTON" or the "Company"), the world's leading public technology company scaling the Telegram super-app with an addressable market of one billion monthly active users, today provided a comprehensive update on strategic initiatives. The Company has raised net $44 million in capital, expanded its AI infrastructure deployment, and is establishing additional revenue-generating partnerships that position AlphaTON as a foundational infrastructure provider for privacy-preserving artificial intelligence.

Balance Sheet Update & Capital Markets Activity

AlphaTON has executed a disciplined capital strategy to fund infrastructure expansion while maintaining financial flexibility:

• Recent Capital Raise: Closed $15 million registered direct offering at $1.00 per share. Majority of net proceeds are allocated to GPU AI infrastructure scaling for Cocoon AI and working capital for the Company.
• Infrastructure Investment: Initiated a $46 million investment in AI infrastructure expansion on January 5, 2026, for a total of 576 NVIDIA B300 chips. This deployment, scheduled for delivery in March 2026, is projected to deliver a 27% IRR, 282% ROI, and a Net Present Value of $11 million.
• SEC Compliance Milestone: Exited SEC "baby-shelf" restrictions on December 3, 2025, filing a $420.69 million shelf registration statement, declared effective December 11, 2025. This provides enhanced financing flexibility for strategic acquisitions and infrastructure deployment.

AI Infrastructure Deployment & Revenue Generation

AlphaTON has rapidly deployed GPU infrastructure to capture the emerging opportunity in privacy-preserving AI compute:

• Cocoon AI Network Launch: Successfully deployed initial B200 GPU fleet on November 30, 2025, coinciding with Telegram's official Cocoon AI network launch. The Company began generating revenue in December from AI inference processing.
• Advanced GPU Deployments: Deployed H200 GPUs on December 8, 2025, and secured first NVIDIA B300 chips with Supermicro HGX systems via Atlantic AI partnership on December 15, 2025. Launched #OwnYourNode program enabling retail and institutional access to fractionalized GPU ownership. Signed purchase order for first half cluster of 576 x B300s for delivery in March 2026.
• Data Center Infrastructure: Executed five-year enterprise colocation agreement with atNorth AB on December 11, 2025, securing 2.2 MW of high-performance computing capacity in Sweden powered by 100% renewable power.

Strategic Partnerships & Technology Integration

AlphaTON has established partnerships that are expected to create additional revenue streams and vertically integrate into the Company's Confidential Compute AI Infrastructure:

• Midnight Foundation Partnership: Signed definitive agreement effective December 2025 establishing AlphaTON as a Founding Federated Node Architecture Provider for privacy-preserving AI. Agreement generates immediate monthly revenue and includes reimbursement for documented network growth costs.
• Claude Connector Launch: Launched AlphaTON Claude Connector on January 21, 2026, an open-source platform combining Anthropic's Claude AI with TON blockchain technology via Telegram. The solution enables mainstream users to manage digital assets through natural-language conversations.
• Alpha Liquid Terminal: Developing Agentic trading and monitoring application that will utilize agents to seek best execution across multiple asset classes including tokenized securities, cryptocurrencies, equities, private shares and real world assets.

Management Commentary

"Since our November 2025 update, AlphaTON has systematically executed our strategy to transform from a passive digital asset holder into an active infrastructure operator generating recurring revenue," said Brittany Kaiser, Chief Executive Officer of AlphaTON Capital. "The net $44 million in capital deployed has positioned us at the forefront of the privacy-preserving AI infrastructure market. Our GPU deployments are generating revenue today, our partnerships with Midnight Foundation and others create scalable revenue models, and we've secured institutional-grade data center capacity to support continued growth. We are building tangible, revenue-generating assets that we believe will drive significant long-term value for the company."

"Since taking over this Nasdaq listed company as management, over the past two months this team has demonstrated our ability to move decisively and deploy capital efficiently," commented Enzo Villani, Executive Chairman and Chief Investment Officer. "We are much more than a digital asset treasury company, we have taken the mantle to develop a vertically integrated Telegram ecosystem company that combines AI and decentralized blockchain infrastructure on Telegram's exclusive blockchain, develop, partner and acquire applications successfully deployed on Telegram, and integrate them to provide additional value to the over 1 billion users on Telegram."

Brittany Kaiser, CEO commented, "Our strategy is simple, build a company that supports Telegram because our mission is focused on the future of privacy-protection and digital identity sovereignty. In our world, owning your ideas and concepts developed with AI is protected, and our goal is to deliver an alternative to centralized technology companies that exploit the user and their information, come join us!"
