Sphere 3D Corp. reported full-year 2025 results showing weaker financial performance while highlighting operational upgrades and a planned merger with Cathedra Bitcoin. Bitcoin mining revenue was $11.2 million, down from $16.6 million in 2024, reflecting the April 2024 halving and fleet transitions.
Total operating costs and expenses fell to $33.2 million from $38.0 million, driven in part by a roughly 33% reduction in general and administrative expenses to $8.3 million. Even so, the company recorded a larger net loss of $21.5 million, compared with a $9.5 million loss in 2024, as investment gains and other income declined sharply.
The company mined 111.6 Bitcoin during 2025 and held 37.3 Bitcoin as of December 31, 2025. Sphere 3D upgraded its fleet to about 2,300 newer-generation miners, improving average efficiency from 27.1 J/th to below 19.0 J/th, and fully energized a new 8MW Iowa facility to lower operating costs.
