PowerCompute Announces August 2026 Production and Operational Update

Bitcoin holdings of 323 BTC valued at approximately $25.2 million as of August 31, 2026

Captured approximately $132,000 in energy sales from curtailment during the month

TAMPA, FL, September 9, 2026 — PowerCompute, Inc. (Nasdaq: PWCM) (“PowerCompute” or the “Company”), a Bitcoin treasury and mining company expanding into high-performance computing (“HPC”) and artificial intelligence (“AI”) infrastructure, today announced its preliminary, unaudited Bitcoin mining and operational update for the month ended August 31, 2026.

“August production of 7.9 Bitcoin was consistent with July, reflecting continued seasonal heat-related curtailment at our Oklahoma and Mississippi sites, which is typical for this time of year,” said Bruce M. Rodgers, Chairman, Chief Executive Officer and President of PowerCompute. “That curtailment generated approximately $132,000 in energy sales during the month, equivalent to approximately 1.7 Bitcoins at the August 31 Bitcoin price. This brought our total energy sales to approximately $223,000 over the past two months. Our ability to monetize our power when it is most valuable to the grid is precisely the flexibility that owning our infrastructure gives us.”

The Company estimates that the value of its 323 Bitcoin holdings on August 31, 2026 was approximately $25.2 million, based on a Bitcoin price of approximately $78,000 as of that date. Of these holdings, 307 Bitcoin are pledged as collateral under the Company's Arch credit facility, against which approximately $21.9 million was outstanding as of August 31, 2026. The remaining 16 Bitcoin are unencumbered.The Company had 2,421,472 shares of common stock outstanding as of August 31, 2026.

“We are continuing our Bitcoin miner refresh, ordering approximately 1,000 miners to replace older S19j Pro units rated at 100 TH/s or below,” said Richard Russell, Chief Financial Officer of PowerCompute. “The new machines are expected to be energized by September 30, 2026. Once online, we estimate our active hash rate will increase by approximately 7%, to a forecasted 825 PH/s from 771 PH/s as of June 30, 2026, on newer and more efficient hardware.”
