The Board would also like to provide a brief update on QBT's attendance at Bitcoin 2025, held last week in Las Vegas. The QBT team held a number of one-on-one meetings where they presented to a number of key companies in the sector, including ASIC chip designers, mining rig manufacturers and pool miners. The meetings included demonstrations of the Company's three disruptive Methods, including a live demonstration of Method A, which was mining in the Company's lab in Milan. A high level of interest was shown by the attending parties. The Company intends to follow up on these meetings over the coming weeks, with the hope that a number of new third-party tests will be requested.

Francesco Gardin, QBT's Executive Chairman and CEO, commented, "Overall, the response to the live demonstrations of QBT's Methods was impressive. Bitcoin 2025 is the largest industry conference in the US, which is the largest market for Bitcoin mining and it gave us the chance to meet with the key players in the Bitcoin mining industry. On the back of this new interest we are committed to driving forward with our products to reach a commercial agreement. As usual, we will keep shareholders updated as and when we have further news to report."
