Dear Shareholders,

I am pleased to announce that we have entered into a definitive agreement to merge with Hut 8, a leading player in the bitcoin mining industry. Upon completion of the merger, the shareholders of Hut 8 and stockholders of USBTC are expected to each own, on a fully-diluted in the money basis, approximately 50% of the combined entity which will be named Hut 8 Corp. This marks a significant milestone for our company and underscores our commitment to growth and innovation.

Pre Hut 8’s 5-to-1 split, every share of USBTC would convert to about 3.3 shares of Hut 8.

For more details, please refer to the official press release and the transaction deck.

Thank you for your support and confidence in our company. We look forward to keeping you updated on our progress.

Best regards,

Asher Genoot
