TL;DR: PowerCompute mined 8.1 BTC in September, up 37% from a year earlier. Its month-end Bitcoin holdings fell to 63.7 BTC after the company used 267.4 BTC to help retire a $22.45 million Bitcoin-backed credit facility, leaving most of its secured debt eliminated.

PowerCompute’s latest mining update is a useful reminder that a corporate Bitcoin treasury can serve more than one purpose.

The Nasdaq-listed miner produced 8.1 BTC in September, a 37% increase from the 5.9 BTC it mined in the same month last year and slightly above August production.

At the same time, its Bitcoin holdings fell sharply.

PowerCompute ended September with 63.7 BTC, down from 323.02 BTC at the end of August.

The reason was debt.

The company used 267.4 BTC to help settle principal and accrued interest on a Bitcoin-backed credit facility with Arch, eliminating approximately $22.45 million of obligations and releasing the collateral attached to the loan.

That reduced secured debt from roughly $23.7 million to $1.25 million.

The remaining borrowing is not secured by Bitcoin.

For public miners, that trade-off is significant.

Bitcoin holdings are often presented as a measure of financial strength, particularly when a company’s market value is compared with the BTC sitting on its balance sheet.

But debt changes the picture.

A large treasury that is pledged against borrowings is not as flexible as unencumbered Bitcoin, and leverage can become particularly painful when BTC prices or mining economics turn against the company.

PowerCompute chose to shrink the treasury substantially in exchange for removing most of that leverage.

Management has framed the decision as using Bitcoin to retire debt rather than carrying the financing cost.

The operational side of the update was more positive.

September production of 8.1 BTC was also up from 7.9 BTC in August.

The company operates 26 megawatts of interconnected power infrastructure across facilities in Oklahoma and Mississippi, while also exploring a broader shift toward high-performance computing and AI-related infrastructure.

PowerCompute also generated about $89,000 from selling electricity back to the grid during periods when seasonal heat made curtailment more attractive than mining.

That illustrates another part of modern mining economics.

A miner with access to flexible power is not always maximizing revenue by running machines continuously. At certain times, the electricity itself can be worth more than the Bitcoin the same power would produce.

PowerCompute said energy sales totaled roughly $312,000 across the three months ended September.

The company’s strategy therefore now sits across several moving pieces: Bitcoin production, power-market economics, debt reduction and potential data-center expansion.

None of them is as eye-catching as simply announcing another BTC purchase.

But the September figures show why balance-sheet quality matters.

PowerCompute owns far less Bitcoin than it did a month earlier.

It also owns that Bitcoin with dramatically less secured debt hanging over it.
