TNL Mediagene (NASDAQ: TNMG) to Establish Digital Asset Treasury

-The Company announces a major strategic initiative to integrate digital assets into its business model and to establish a digital asset treasury (“DAT”), with digital assets limited to BTC, ETH and SOL — the three most established digital assets — designated as part of the Company’s treasury assets.

TNL Mediagene (Nasdaq: TNMG) (the “Company”), a Tokyo-based next-generation digital media and data group in Asia, today announced a major strategic initiative to integrate digital assets into its business model and to implement a digital asset treasury strategy (“DAT Strategy”) pursuant to which digital assets limited to BTC, ETH and SOL will become part of the Company’s treasury assets. The Company emphasizes that its DAT Strategy will exclude other digital assets that do not meet standards of scale, liquidity, institutional adoption and regulatory transparency.

The Company has also formed a DAT advisory group (“DAT Advisory Group”) to guide oversight, evaluation and development of the DAT Strategy. The DAT Advisory Group comprises experts in the fields of digital assets, blockchain and Web3 which will advise the management and the board of directors to ensure industry best practices and compliance with legal and regulatory requirements. These experts bring prior and concurrent experience from leading digital asset and Web3 companies, such as CoinDesk and Matter Labs. Their backgrounds span trading, asset management, product development and regulatory engagement, providing the Company with a broad base of industry expertise.

The DAT Strategy is designed to deliver both financial and strategic benefits. Financially, it can enhance the Company’s flexibility and strengthen its position for future growth initiatives including acquisitions. Strategically, it opens new business opportunities in the digital asset space where the Company can leverage its scale, media reach and data analytics expertise. Unlike companies that position themselves primarily as digital asset treasury vehicles, the Company’s strategy is intended to complement — not replace — its core Media, Technology and Digital Studio businesses. The Company also recognizes that digital assets can be volatile and subject to regulatory or technological risks. Accordingly, its DAT Strategy is limited to BTC, ETH and SOL, which it views as the most established and widely adopted digital assets, and will be implemented in a gradual and disciplined manner to balance potential benefits with prudent risk management.

The Company has identified BTC, ETH and SOL as the digital assets most suitable for its treasury, given their relative scale, liquidity, institutional adoption and track records across multiple market cycles. Each of these assets provides distinct benefits — BTC as a widely recognized store of value, ETH as the leading smart-contract platform and SOL as a high-performance blockchain with one of the fastest-growing developer communities. Collectively, these three digital assets represent the pillars of today’s DAT ecosystem.

With guidance from the DAT Advisory Group, the Company is engaged in a comprehensive process, speaking with financing partners, refining potential investment and management policies, and considering different execution paths. The Company is also engaging with leading institutional custodians and asset managers to ensure best-in-class security, governance and compliance. The Company expects to finalize key details of its DAT Strategy, including the allocation of treasury assets, the timing of financing of digital assets and the potential selection of service providers in the coming months.

“We see tremendous potential in digital assets and the multitude of ways a DAT Strategy can benefit and create synergies with our existing high-growth, high-visibility media business of 45 million monthly unique users^*1, as well as our and data and technology business lines. Over the years, we have scaled our company through a disciplined M&A roll-up strategy, acquiring and integrating media and technology properties across Asia. The DAT Strategy builds on that foundation — not only by potentially enhancing our financial flexibility and liquidity to pursue future acquisitions, but also by positioning us to expand our media and data analytics platforms into the digital asset space anchored by these leading blockchains. We believe this dual benefit — financial and strategic — can support the next phase of our roll-up strategy and create significant new avenues of growth and shareholder value,” Co-Founder & CEO Joey Chung commented.

“Over the past several years, Japan’s crypto market has developed into one of the more robust and regulated markets globally, and in recent months this maturation has accelerated, with growing investor interest and pending tax reforms — including a proposal to move from progressive rates up to 55% toward a flat 20% rate by FY2026 — suggesting space for broader participation under clearer policy frameworks. Our M&A roll-up approach has always been about extending our reach, diversifying our portfolio and identifying where market shifts open new opportunities. Our DAT Strategy is a natural evolution of that playbook, focused only on BTC, ETH and SOL, and excluding other digital assets that do not meet standards of scale, liquidity, institutional adoption and regulatory transparency. Our DAT Strategy not only has the potential to strengthen our treasury and acquisition capacity but also opens a pathway for us to build and partner with businesses native to the digital asset economy. In doing so, we can leverage our media scale and audience reach to capture revenue opportunities in a sector that is rapidly converging with mainstream technology and consumer behavior. We see this as a powerful extension of our roll-up strategy and are excited to move forward,” Co-Founder & President Motoko Imada added.
