Management Commentary

In December, in addition to operating its first three data centers, Cipher continued its buildout at Odessa at maximum velocity. Cipher started the month with the potential to mine up to ~3.6 bitcoin in a day at Odessa and finished with the potential to mine ~6.6 bitcoin in a day at the site¹ — an ~84% increase in a single month.

"This rapid progress demonstrates the expertise of our amazing deployment and operations teams," said Tyler Page, CEO of Cipher. "As is always the case at Cipher, we maintained a relentless focus on cost discipline, and announced during the month that we had purchased 7,200 new rigs at very attractive prices, bringing our total purchased fleet for self-mining to over 59,000 rigs. As we turn the calendar to look toward 2023, we remain focused on completing Odessa as quickly as we can. With an additional ~31,000 fully-paid-for rigs on site or in transit to Odessa, we anticipate expanding our self-mining capacity to ~6 EH/s in the first quarter of the year."
