Cathedra Bitcoin Inc. announce the following updates on its bitcoin mining operations. In September, the Company responded to worsening mining conditions by underclocking approximately 1,600 of its S19J Pro machines hosted in various data centers in Tennessee and Kentucky through the use of after-market firmware. In doing so, the Company was able to achieve approximately 80 TH/s per machine at an efficiency level of 26.3 J/TH, thereby increasing operating profits and reducing breakeven hash price to a weighted average of $48/PH/s/day across these machines.

This has reduced the Company's expected fleetwide hash rate to 355 PH/s, while also reducing fleetwide breakeven hash price to $43/PH/s/day (vs. US$45/PH/s/day previously). Additionally, in September, the Company also completed the initial deployment of its off-grid mining partnership with 360 Mining in Texas.

With the deployment of its first Rover, the Company becomes the only publicly traded bitcoin miner using both on- and off-grid energy sources to power its operations. Finally, the Company streamlined its operations by relocating machines from its third-party data center in Kentucky to one of its existing third-party data centers in Tennessee. The relocation did not affect the terms of the existing hosting agreement.
