Sphere 3D Corp.
ANYBusiness Summary
Sphere 3D Corp. operates in the blockchain and cryptocurrency industry, specifically focusing on Bitcoin mining. The company commenced its Bitcoin mining operations in January 2022 and aims to be a leader in this sector. Its business model revolves around acquiring specialized computer servers, known as ASIC miners, and deploying them at scale through hosting agreements and self-owned facilities to perform hash calculations for mining pool operators. The company generates revenue by earning newly minted Bitcoin and transaction fees as rewards for its mining efforts 1. In December 2023, Sphere 3D Corp. divested its service and product segment, which previously focused on containerization, virtualization technologies, and data management products, to concentrate solely on growing its Bitcoin mining operation 2.
The company's core business model involves providing hash calculation services to Bitcoin mining pool operators. This is its sole performance obligation, and it receives non-cash consideration in the form of Bitcoin based on the Full Pay Per Share (FPPS) payout method 3. This method entitles the company to a fractional share of the fixed Bitcoin award and transaction fees, regardless of whether the mining pool operator successfully records a block to the blockchain 4. The contracts for these services are short-term, less than 24 hours, and continuously renew, with compensation based on current market rates 5. The company employs a hybrid treasury strategy, holding Bitcoin when possible and selling it to fund working capital requirements 6.
As of December 31, 2025, Sphere 3D Corp. owned approximately 12,600 miners, with about 4,200 in service, contributing a total hashrate capacity of 0.73 exahash per second (EH/s) 7. The company has been actively refreshing its miner fleet with newer-generation machines to enhance efficiency 8. This strategic shift included the sale of approximately 7,700 older generation miners in February 2026 in exchange for 437 newer generation miners, substantially completing the refresh 9. The company also began operating a self-owned 8-megawatt (MW) facility in Iowa in March 2025, which is part of its vertical integration strategy to reduce reliance on third-party hosting and lower mining costs 10. The average efficiency of miners owned as of December 31, 2025, was 22.0 J/th, an improvement from 27.1 J/th in 2024 11.
For the fiscal year ended December 31, 2025, Sphere 3D Corp. reported total revenue of $11.2 million 12, a decrease from $16.6 million in 2024 13. The cost of revenue (exclusive of depreciation and amortization) was $8.6 million in 2025, down from $13.4 million in 2024 14. General and administrative expenses decreased to $8.3 million in 2025 from $12.4 million in 2024 15. Depreciation and amortization expense was $6.9 million in 2025, compared to $7.1 million in 2024 16. The company recorded an impairment of property and equipment of $7.2 million in 2025, significantly higher than $1.1 million in 2024 17. Loss on disposal of property and equipment was $1.7 million in 2025, down from $3.5 million in 2024 18. The change in fair value of Bitcoin resulted in a loss of $0.3 million in 2025, contrasting with a gain of $0.7 million in 2024 19. Impairment of other assets was $0.3 million in 2025, compared to $1.1 million in 2024 20. The net loss for 2025 was $21.5 million, compared to $9.5 million in 2024 21. Basic and diluted EPS for 2025 was $(7.37) 22, versus $(4.78) in 2024 23. Cash and cash equivalents stood at $3.7 million as of December 31, 2025, a decrease from $5.4 million at December 31, 2024 24. The company had working capital of $6.9 million at December 31, 2025 25.
Year-over-year, revenue decreased by $5.4 million 26, or 32.5%, primarily due to the April 2024 halving event and the transition to newer mining equipment 27. Cost of revenue decreased by $4.8 million 28, or 35.8%, driven by lower hosting fees and the transition to the Iowa Site 29. General and administrative expenses saw a $4.1 million reduction 30, or 32.9%, mainly from decreased share-based compensation, legal fees, and employee expenses, partially offset by increased strategic business growth costs 31. The impairment of property and equipment increased substantially by $6.1 million 32, or 554.5%, reflecting the decline in Bitcoin price 33. Bitcoin mined decreased by 61.0% from 286.3 Bitcoin in 2024 to 111.6 Bitcoin in 2025 34.
During the reported period, Sphere 3D Corp. made several significant operational developments. On March 5, 2026, the company entered into a definitive agreement to acquire Cathedra Bitcoin Inc. in an all-stock transaction, aiming to create a high-density computing power infrastructure company focused on high-performance compute, digital assets, energy optimization, and power and infrastructure development 35. This combination is expected to enable near-term vertical integration and accelerate scalable, high-efficiency deployment across North America 36. In February 2026, the company sold approximately 7,700 older generation miners for 437 newer generation miners with a value of $1.1 million, substantially completing its miner fleet refresh 37. The company also completed the infrastructure for its self-owned 8 MW Iowa Site in March 2025 38 and entered into a management services agreement with Simple Mining LLC to manage this site 39. Additionally, in January 2025, the Rebel Hosting Agreement was terminated, resulting in a settlement amount of $2.4 million payable to the company, though $0.3 million of this was impaired due to default 40.
Business Outlook
Sphere 3D Corp. anticipates continuing to increase its exahash throughout 2026, based on existing operations and expected deployment of purchased miners 41. The company expects its miner efficiency to improve to approximately 19.0 J/th in 2026, down from 22.0 J/th in 2025 42. This improvement in efficiency is a key part of its strategy to minimize the cost of running miners and earning Bitcoin 43.
A major growth area for the company is the strategic combination with Cathedra Bitcoin Inc., announced on March 5, 2026 44. This all-stock transaction aims to create a high-density computing power infrastructure company with a focus on high-performance compute, digital assets, energy optimization, and development of power and infrastructure 45. The strategic combination is expected to enable near-term vertical integration, positioning the new entity to accelerate scalable, high-efficiency deployment across North America by leveraging low-cost power and operational efficiency 46. If the Arrangement Agreement is terminated under certain circumstances, either party would be required to pay a termination fee of $0.5 million 47.
Operationally, the company is focused on transitioning to lower-cost hosting sites, vertically integrating to own its own sites, and refreshing its fleet with newer-generation machines 48. These strategic changes have led to a decrease in mining production during the latter part of 2024 and ongoing, as the company prioritizes long-term goals 49. The company expects to continue taking steps to lower its cost of mining and refresh its mining fleet to increase mining efficiency 50.
Regarding capital allocation, Sphere 3D Corp. has an At-the-Market (ATM) offering program with A.G.P./Alliance Global Partners, allowing it to sell common shares with an aggregate offering price of up to $8.0 million 51. For the year ended December 31, 2025, 112,791 common shares were issued through this program for net proceeds of $0.7 million 52. The company expects to use any proceeds from this facility primarily for working capital, general corporate purposes, and to accelerate efficiency, purchase/upgrade its mining fleet, and for vertical integration of infrastructure 53. In October 2025, the company completed a warrant inducement agreement, resulting in gross cash proceeds of $4.1 million from the exercise of warrants at a reduced price of $9.40 per share, before deducting $0.4 million in financial advisor fees and other transaction expenses 54. The net proceeds from this transaction were used for the purchase or upgrade of its Bitcoin mining fleet and other general corporate purposes 55. The company has not declared or paid any dividends to date and intends to retain future earnings to support business development, not anticipating cash dividends in the foreseeable future 56.
Management has projected that based on recurring losses, negative cash flows from operating activities, and its hashing rate at December 31, 2025, cash on hand may not be sufficient to allow operations to continue, raising substantial doubt about its ability to continue as a going concern within 12 months from the date of issuance of its financial statements if additional funding is not secured 57. The company's ability to raise additional funds depends on its financial success, strategic initiatives, and market conditions, some of which are beyond its control 58. Significant changes from current forecasts, such as shortfalls from projected mining earnings, increases in operating costs, decreases in cryptocurrency value, or non-compliance with Nasdaq listing requirements, could materially impact its ability to access necessary funding 59.
Risk Factors
Sphere 3D Corp. faces substantial risks, primarily driven by the highly volatile nature of Bitcoin prices and transaction volumes, which directly impact its revenue, operating results, and financial condition 60. The company is exposed to significant competition in the Bitcoin mining industry, with increasing pressure for access to mining rewards, power, and high-quality industrial-scale mining infrastructure, which is in limited supply 61. Regulatory changes, particularly concerning energy consumption and environmental policies, could impose significant costs, restrict operations, or even lead to bans on Bitcoin mining in certain jurisdictions, such as the two-year moratorium on proof-of-work mining permits at fossil fuel plants in New York 62. Operational risks include reliance on hosting arrangements, which are uncertain and competitive, and the potential for downtime at hosting sites due to weather or heat 63. The company is also dependent on a small number of Bitcoin mining equipment suppliers, making it vulnerable to supply chain disruptions, price fluctuations, and shortages of critical components like ASIC chips 64. There is a risk of technological obsolescence, requiring continuous investment in newer, more efficient miners to remain competitive 65. Cybersecurity threats, including hacks and malicious attacks, pose a risk to the company's Bitcoin holdings and operational systems, potentially leading to losses or disruptions 66. Furthermore, there is substantial doubt about the company's ability to continue as a going concern within 12 months due to recurring losses and negative cash flows, necessitating additional funding 67. The classification of cryptocurrency as investment securities by regulatory bodies could subject the company to the Investment Company Act of 1940, incurring significant expenses or requiring operational restructuring 68.
Management Priorities
Management's message emphasizes a strategic pivot towards becoming a leader in the blockchain and cryptocurrency industry, specifically through Bitcoin mining, following the sale of its legacy service and product segment in December 2023 69. A key strategic priority is the ongoing refresh of its miner fleet with newer-generation machines to bolster efficiency, aiming for an improved average efficiency of approximately 19.0 J/th in 2026 70. Another core strategic focus is vertical integration, exemplified by the establishment of a self-owned 8 MW facility in Iowa in March 2025, intended to reduce reliance on third-party hosting and decrease the overall cost to mine Bitcoin 71. Management also highlights the recently announced definitive agreement to combine with Cathedra Bitcoin Inc. on March 5, 2026, as a move to create a high-density computing power infrastructure company, anticipating near-term vertical integration and accelerated scalable, high-efficiency deployment across North America 72. Despite these growth initiatives, management explicitly acknowledges the substantial doubt about the company's ability to continue as a going concern within 12 months, citing recurring losses and negative cash flows, and stresses the need to raise additional funding for operations 73.
