Highlights of the Partnership:

• Digital Currency Treasury Program: PowerBank will accumulate Bitcoin and Intellistake will accumulate digital currencies that support decentralized AI. .
• Bitcoin Treasury Management: Intellistake will help manage digital asset operations for PowerBank and serve as PowerBank’s supporting partner for security, custody, and treasury management.

VANCOUVER, BRITISH COLUMBIA July 31, 2025 – POWERBANK CORPORATION (NASDAQ: SUUN; Cboe CA: SUNN, FSE: 103) (“PowerBank” or the “Company“) – announces a transaction with Intellistake Technologies Corp. (“Intellistake”) that involves the intersection of digital assets, energy, and tokenized finance. Intellistake (CSE: ISTK) is a technology company bridging traditional capital markets with decentralized AI and blockchain infrastructure, and PowerBank (formerly SolarBank), is a leader in clean energy infrastructure.

Together, these two high-growth companies will pursue three seminal initiatives:

• A Digital Asset Treasury Program: Leveraging Bitcoin as a long-term treasury reserve asset, PowerBank, with Intellistake’s support, intends to accumulate and hold Bitcoin on its balance sheet and Intellistake intends to accumulate digital assets that support decentralized AI, such as FET Token — aligning with the global shift toward decentralized financial reserves.
• Bitcoin Treasury Management: Under the partnership framework, Intellistake will help manage digital asset operations for PowerBank and serve as PowerBank’s supporting partner for security, custody, and treasury management of Bitcoin.
• The Tokenization of Real-World Assets (RWA): Intellistake and PowerBank are evaluating the potential tokenization of PowerBank’s clean energy assets or shares — providing an investment and financing alternative.

“Tokenization is no longer a concept—it’s an inevitability,” said Jason Dussault, CEO of Intellistake. “By combining our expertise in capital markets and digital asset custody with PowerBank’s scalable, real-world energy platform, we’re unlocking a new opportunity..”

As institutions and sovereign funds increasingly embrace tokenized securities and decentralized asset strategies, the Intellistake–PowerBank partnership centres on transforming legacy energy systems into a tokenized product.

According to a recent report by CryptoSlate, analysts forecast that the market cap for tokenized real-world assets (RWAs) could reach $30 trillion by 2034(1)—driven by advances in blockchain, AI, and investor demand for transparent, real-time asset ownership and settlement.

“This partnership is about more than collaboration—it’s about setting the pace for a shift in how companies manage capital and assets,” said Dr. Richard Lu, CEO of PowerBank. “As the world accelerates toward AI, automation, and clean energy, Bitcoin and tokenization are presenting new opportunities. PowerBank and Intellistake are here to take part in that transformation, to bridge traditional energy infrastructure with the demand of the digital economy.”

Intellistake and PowerBank are presently evaluating the regulatory framework for tokenization. Any tokenization will be subject to it being completed in compliance with applicable law, regulatory requirements and terms of any underlying agreements associated with PowerBank assets. The actual structure of such tokenization, the assets that would be subject to tokenization, and the associated timeline, have not yet been determined. Intellistake and PowerBank will provide further updates as material developments related to this tokenization strategy occur.

The actual timing and value of Bitcoin purchases, under the allocation strategy will be determined by management. Purchases will also depend on several factors, including, among others, general market and business conditions, the trading price of Bitcoin and the anticipated cash needs of Intellistake or PowerBank. The allocation strategy may be suspended, discontinued or modified at any time for any reason. Intellistake will support PowerBank’s establishment of custody for its digital currency purchases and PowerBank no longer intends to utilize Coinbase for this service. As of the date of this press release, no Bitcoin purchases have been made.
