Sphere 3D Corp. is a Bitcoin mining company that operates in the blockchain and cryptocurrency industry, focusing on acquiring and deploying application specific integrated circuit (ASIC) miners to validate transactions on the Bitcoin blockchain.

The company generates revenue primarily from its mining operations, where it earns block rewards and transaction fees by contributing computational power to the network, and from providing hash calculation services to mining pool operators under full pay per share contracts. Additionally, revenue is realized when the company sells mined Bitcoin on the open market to convert holdings into U. S. dollars for working capital and strategic initiatives. The company also holds a portion of its mined Bitcoin on its balance sheet as a digital asset, which can be liquidated based on market conditions and treasury policy.

Following the divestiture of its service and product segment in December 2023, Sphere 3D Corp. operates through a single business segment dedicated to Bitcoin mining, which is treated as its only reportable operating segment for financial disclosure purposes.

• Bitcoin mining: This segment involves the purchase of ASIC miners, their deployment at the company's owned eight megawatt facility in Iowa and through various hosting agreements, and the ongoing management of the fleet to maximize hashrate and operational efficiency. As of December 31, 2025, the company owned approximately 12,600 miners, of which about 4,200 were in service delivering a total hashrate capacity of 0.73 exahash per second. After selling roughly 7,700 older generation miners and acquiring 437 newer generation units in early 2026, the active fleet consisted of approximately 5,300 miners. The mining operation produced 111.6 Bitcoin in 2025, representing a decline of 61.0% compared with 286.3 Bitcoin mined in 2024, primarily due to the April 2024 halving event, fleet transition and site relocation activities. The average energy efficiency of the owned miners improved to 22.0 joules per terahash in 2025 from 27.1 joules per terahash in 2024, with an expected further improvement to approximately 19.0 joules per terahash in 2026. The company continues to refresh its hardware to maintain competitiveness and lower the cost per Bitcoin mined.

Sphere 3D Corp. competes in a highly fragmented Bitcoin mining industry that includes numerous public and private operators seeking to earn block rewards and transaction fees. Competitive dynamics are influenced by Bitcoin market prices, the overall network hashrate, and the availability of low cost power sources. The company's competitive advantages stem from its owned eight megawatt facility in Iowa, which provides direct control over power costs and infrastructure, and its continuous fleet refresh with newer generation ASIC hardware that improves energy efficiency. Additionally, the pursuit of vertical integration through self owned sites and strategic hosting arrangements reduces reliance on third party providers and lowers the overall cost to mine each Bitcoin.

The company's customer base consists primarily of mining pool operators to which it supplies hash calculation services under contractual agreements; notable partners include Foundry Digital LLC and Luxor Technology Corporation. In addition, Sphere 3D Corp. sells the Bitcoin it mines to exchanges and institutional buyers, thereby completing the revenue cycle from mining to monetization. The firm also maintains a treasury policy that determines when to hold or sell Bitcoin based on market forecasts and liquidity requirements, further shaping its interactions with the broader digital asset market.
