Facing a severe cash crunch, Bitcoin miner Sphere 3D quietly prepares to dilute its shareholders by a staggering 50%

Bitcoin miner Sphere 3D has up to $10.3 million of amended at-the-market stock-sale capacity for working capital, while its standing policy also permits mined Bitcoin sales for working capital or growth.

At the assumed $2.35 share price in its July 31 prospectus supplement, full use of the facility would add 4,382,978 common shares and expand the company’s basic share count by 50.9%.

That sale would lift basic shares outstanding from 8,619,150 to 13,002,128. The amended facility replaced Sphere 3D’s prior ATM prospectus. It is authorization, not a completed issuance: A.G.P. and Maxim are not required to sell a minimum amount, and the number of shares issued will depend on actual market prices.

The 4,382,978 new shares would represent about 33.7% of the resulting basic total, leaving shares already outstanding at about 66.3%. However, the filing’s base excludes stock options, restricted stock units and restricted stock awards, preferred-share conversion shares, warrants and shares reserved for future equity awards.

Sphere 3D estimates approximately $9.9 million of net proceeds if the full assumed offering is sold, after the 3% sales-agent commission and estimated offering expenses. Its prior program shows the equity channel has already been used: a companion Form 8-K says the company sold 2,172,789 shares under the superseded prospectus through July 30 for $5.13 million of gross proceeds. Those sales do not represent use of the amended facility.

Bitcoin remains a working-capital fallback

The latest available combined baseline predates the ATM amendment. Pro forma accounts as of March 31 showed $3.38 million of cash and $2.06 million of digital currencies for Sphere 3D and Cathedra combined. The figures model the merger as if it had occurred on that date and are not current post-closing balances.

Sphere 3D’s standalone quarterly accounts reported $3.15 million of cash and 26.2 BTC with a balance-sheet fair value of $1.79 million at March 31. The company generated $2.79 million of Bitcoin-sale proceeds during the quarter and said all dispositions funded operations.

Its July prospectus says management may continue selling mined Bitcoin when needed for working capital or growth; it describes a policy option and identifies no specific Bitcoin sale order.

That flexibility sits against documented liquidity pressure. Sphere 3D’s 2025 audit contained a going-concern explanatory paragraph, while Cathedra’s audit included a separate going-concern matter. Cathedra’s March 31 interim accounts also reported a C$4.35 million working-capital deficiency and C$1.17 million of net cash used in operating activities during the quarter.

As of an Aug. 3 check of Sphere 3D’s SEC submissions feed, no subsequent company filing had disclosed sales under the amended facility. That does not rule out trades that could be reported later.

Until a later disclosure, the measurable exposure is the filed capacity: up to 50.9% more basic shares, alongside a standing policy that treats Bitcoin as operating liquidity.
