Item 1. Business

Overview

Sphere 3D was incorporated under the Business Corporations Act (Ontario) on May 2, 2007 as T.B. Mining Ventures Inc. On March 24, 2015, we completed a short-form amalgamation with a wholly-owned subsidiary. In connection with the short-form amalgamation, we changed our name to “Sphere 3D Corp.” Any reference to the “Company”, “Sphere 3D”, “we”, “our”, “us”, or similar terms refers to Sphere 3D Corp. and its subsidiaries. In January 2022, we commenced operations of our Bitcoin mining business and are dedicated to becoming a leader in the blockchain and cryptocurrency industry. We have established and continue to grow an enterprise-scale mining operation through the procurement of mining equipment and partnering with experienced service providers. In December 2023, we sold our service and product segment which focused on containerization and virtualization technologies along with data management products that enabled workload-optimized solutions. We plan to continue to focus on growing our Bitcoin mining operation.

On February 9, 2026, we filed an Articles of Amendment to effect a share consolidation (also known as a reverse stock split) of our issued and outstanding common shares in the ratio of 1-for-10. The share consolidation was effective on February 9, 2026. Our common shares began trading on an adjusted basis on the Nasdaq Capital Market at the opening of trading on February 10, 2026. All share and per share amounts have been restated for all periods presented to reflect the share consolidation.

Business Combination

On March 5, 2026, we and Cathedra Bitcoin Inc. (“Cathedra”), entered into a definitive agreement to combine the two companies, in an all-stock transaction, to create a high density computing power infrastructure company focused on high-performance compute, digital assets, energy optimization, and development of power and infrastructure. The strategic combination is anticipated to enable near-term vertical integration, positioning the new entity to accelerate scalable, high-efficiency deployment across North America by leveraging a focus on low-cost power, and operational efficiency. Under the terms of the definitive arrangement agreement, entered into on March 5, 2026 (the “Arrangement Agreement”), we have agreed to acquire all of the issued and outstanding shares of Cathedra (the “Transaction”), subject to customary closing conditions, including regulatory, court, and shareholder approvals, such that upon consummation of the Transaction, Cathedra will be a wholly-owned subsidiary of the Company. If the Arrangement Agreement is terminated in certain specified circumstances, we or Cathedra would be required to pay the other party a termination fee of $0.5 million.

Bitcoin and Blockchain

Bitcoin is a decentralized digital currency that operates on a peer-to-peer network, allowing users to send and receive payments without relying on banks or central authorities. It runs on a public blockchain, a distributed ledger where all transactions are recorded and secured through cryptographic verification. Within the Bitcoin ecosystem, there are three key participants: users, miners, and nodes. Users are individuals or businesses that send, receive, or store Bitcoin, typically using wallets. Miners are participants who use computational power to solve complex mathematical puzzles, validating transactions and adding them to the blockchain in exchange for newly minted Bitcoin and transaction fees as a reward for their work. Nodes are computers that maintain a full copy of the blockchain and help verify transactions, ensuring the network remains secure and decentralized. Together, these participants enable Bitcoin to function as a trustless, borderless, and censorship-resistant financial system.

In the Bitcoin network, transactions must be validated before they are added to the blockchain. When a user initiates a transaction, it is broadcast to the network and enters the mempool, where it awaits confirmation. Full nodes verify the transaction by checking the sender’s balance and digital signature against the blockchain’s history. Once verified, miners compete to include the transaction in a new block through a process called Proof of Work, where they solve a complex cryptographic puzzle to find a valid hash that meets the network’s difficulty requirements. The first miner to solve the puzzle broadcasts the new block to the network, and if other nodes verify its validity, it is permanently added to the blockchain. As a reward for securing the network, the winning miner receives a block reward, which consists of newly minted Bitcoin, currently 3.125 BTC, along with transaction fees paid by users. Over time, as the block reward continues to halve approximately every four years, transaction fees will become an increasingly important incentive for miners to continue securing the network. This system ensures Bitcoin remains decentralized, secure, and resistant to inflation.

Bitcoin Mining

We obtain Bitcoin as a result of our mining operations, and when necessary, we sell Bitcoin to support our operations and strategic growth. We mine Bitcoin in states which do not have any material state-specific regulatory restrictions on the mining of Bitcoin. However, it is possible that these states or other states in which we may seek to operate may create laws that would impede Bitcoin mining. We do not currently plan to engage in regular trading of Bitcoin other than sales to convert our Bitcoin into U.S. dollars. Decisions to hold or sell our Bitcoin is currently determined by management by analyzing forecasts and monitoring the market in real time. We have a hybrid treasury strategy to hold Bitcoin when possible and sell to fund working capital requirements.

A key component of the Bitcoin mining business segment is to acquire highly specialized computer servers (known in the industry as “miners”), which operate application-specific integrated circuit (“ASIC”) chips designed specifically to mine Bitcoin, and deploy such miners at-scale utilizing our hosting agreements. ASIC miners are the most effective and energy-efficient machines available today, and we believe deploying them at-scale, will enable us to continue growing our hashrate and optimize the output and longevity of our miners as they are deployed.

Our Bitcoin mining operation is focused on maximizing our ability to successfully mine Bitcoin by growing our hashrate (the amount of computer power we devote to supporting the Bitcoin blockchain), to increase our chances of successfully creating new blocks on the Bitcoin blockchain (a process known as “proof of work”). Generally, the greater share of the Bitcoin blockchain’s total network hashrate (the aggregate hashrate deployed to solving a block on the Bitcoin blockchain) a miner’s hashrate represents, the greater that miner’s chances of solving a block and, therefore, earning the block reward. As the proliferation of Bitcoin continues and the market price for Bitcoin increases, we expect additional miner operators to enter the market in response to an increased demand for Bitcoin which we anticipate to follow increased Bitcoin prices. As these new miner operators enter the market and as increasingly powerful miners are deployed in an attempt to solve a block, the Bitcoin blockchain’s network hashrate grows, meaning an existing miner must increase its hashrate at pace commensurate with the growth of network hashrate to maintain its relative chance of solving a block and earning a block reward. As we expect this trend to continue, we will need to continue growing our hashrate to compete in our dynamic and highly competitive industry.

As of December 31, 2025, we owned approximately 12,600 miners, of which approximately 4,200 were in service and have a total hashrate capacity of 0.73 exahash per second (“EH/s”). We are strategizing for our future growth by refreshing a significant portion of our fleet with newer-generation machines to bolster efficiency. Beginning March 2025, we have a self-owned 8 megawatt (‘MW”) facility in Iowa (“Iowa Site”). As of February 2026, with the sale of approximately 7,700 older generation miners not in service for 437 newer generation miners, we have approximately 5,300 miners and our refresh of our miner fleet is substantially complete. Vertically integrating with self-owned facilities, such as our Iowa Site, allows us to reduce our reliance on third-party hosting sites and decrease our overall cost to mine a Bitcoin. As a result of our strategic changes, during the latter part of 2024 and ongoing, mining production has decreased as we focused on our long-term strategic goals of transitioning to lower-cost hosting sites, vertically integrating to own our own site, and refreshing our fleet with newer-generation machines.

In 2025, we mined 111.6 Bitcoin, which represented a decrease of 61.0% over the 286.3 Bitcoin we mined in 2024. The decrease was primarily due to the April 2024 halving event, our transition to lower-cost hosting sites, and refreshing our fleet with newer-generation machines. Based on our existing operations and expected deployment of miners we have purchased, we anticipate continuing to increase exahash throughout 2026. We do not have scheduled downtime for our miners. We periodically perform both scheduled and unscheduled maintenance on our miners. Depending on the type of repair, the miner may run at a reduced speed or be taken offline. We use software programs to monitor the performance of our machines. The miners owned as of December 31, 2025 have an average efficiency (joules per terahash – “J/th”) of 22.0 J/th compared to an average efficiency of 27.1 J/th in 2024. We expect efficiency to improve in 2026 to approximately 19.0 J/th. The miner efficiency is an indication of how efficiently we can earn Bitcoin and minimize cost to run the miner. Currently, we intend only to mine Bitcoin and we hold no other cryptocurrency other than Bitcoin. We do not have any power purchase agreements for the supply of power.

As of December 31, 2025, we held approximately 37.3 Bitcoin with a fair value of approximately $3.3 million included on our consolidated balance sheet.

Mining Pools

A mining pool is a service operated by a mining pool operator that pools the resources of individual miners to share their processing power over a network. Mining pools emerged in response to the growing difficulty and network hash rate competing for Bitcoin rewards on the Bitcoin blockchain as a way of lowering costs and reducing the risk of an individual miner’s mining activities. The mining pool operator coordinates the computing power of the independent mining enterprises participating in the mining pool. Mining pools are subject to various risks such as disruption and down time. In the event that a pool we utilize experiences down time or is not yielding returns, our results may be impacted.

We are engaged with a Bitcoin mining pool operator as our customer, to provide a service to perform hash calculations for the mining pool operator, which is our only performance obligation. Providing hash calculation services is an output of our ordinary activities. We have a service agreement with Foundry Digital LLC, a mining pool operator, to provide a service to perform hash calculations. In exchange for providing the service, we are entitled to Full Pay Per Share (“FPPS”), which is a fractional share of the fixed Bitcoin award the mining pool operator receives, plus a fractional share of the transaction fees attached to that blockchain less net Bitcoin fees due to the mining pool operator over the measurement period, as applicable. The pay-outs received are based on the expected value from the block reward plus the transaction fee reward, regardless of whether the mining pool operator successfully records a block to the blockchain. In 2024 we also had a service agreement with an additional mining pool operator, Luxor Technology Corporation.

Our fractional share is based on a contractual formula, which primarily calculates the hashrate provided to the mining pool as a percentage of total network hashrate and other inputs. The contracts, which are less than 24 hours and continuously renew throughout the day, are terminable at any time by either party without compensation and our enforceable right to compensation only begins when we start providing the service to the mining pool operator, which begins daily at midnight Universal Time Coordinated (“UTC”). The terms, conditions, and compensation are at the current market rates, and accordingly the renewal option is not a material right. The contract arises at the point that we provide hash calculation services to the mining pool operator, which is the beginning of the contract day at midnight UTC time (contract inception), as customer consumption is in tandem with daily earnings of delivery of the service. According to the customer contract, daily earnings are calculated from midnight-to-23:59:59 UTC time, and the payout is made one hour later at 1:00 AM UTC time.

Hosting Agreements

On November 1, 2025, we entered into a Hosting Agreement with North Campbell HostCo LLC (the “Campbell Hosting Agreement”), for rack space, network services, electrical connections, routine facility maintenance, and technical support of certain of our mining equipment. The Campbell Hosting Agreement has an initial term of 12 months and can be terminated based on certain defaults defined in such agreements.

On April 19, 2024, we entered into a Master Hosting Agreement with Simple Mining LLC (“Simple Mining”) for rack space, network services, electrical connections, routine facility maintenance, and technical support of certain of our mining equipment. On September 25, 2024, we entered into Amendment No. 2 to the Master Hosting Agreement (“Simple Mining Hosting”) for certain of our mining machines to be hosted at Simple Mining’s facility in Iowa. The Simple Mining Hosting agreement has a term of two years and can be terminated by us with 30 days advance notice. On September 25, 2024, we entered into Amendment No. 3 to the Master Hosting Agreement (“Simple Mining XP Hosting”) for certain mining machines to be racked at Simple Mining’s facility in Iowa until our Iowa Site was completed. The Simple Mining XP Hosting agreement can be terminated by us with 30 days advance notice. In November 2025, the Simple Mining Hosting and Simple Mining XP Hosting agreements were mutually terminated.

On October 18, 2023, we entered into a Hosting Agreement with Joshi Petroleum, LLC (the “Joshi Hosting Agreement”) for rack space, network services, electrical connections, routine facility maintenance, and technical support of certain of our mining equipment. The Joshi Hosting Agreement has an initial term of three years with subsequent one year renewal periods until either party provides written notice to the other party of its desire to avoid and given renewal term at least 30 days in advance of the conclusion of the prior initial term or renewal period. Effective January 2, 2026, the Joshi Hosting Agreement was assigned to Evolution Technology LLC.

On April 4, 2023, we entered into a Master Hosting Services Agreement with Rebel Mining Company, LLC (the “Rebel Hosting Agreement”) for rack space, network services, electrical connections, routine facility maintenance, and technical support of certain of our mining equipment. The Rebel Hosting Agreement had a term of three years with subsequent one year renewal periods. During the year ended December 31, 2024, we recorded a $0.9 million impairment to prepaid service fees held by Rebel Mining Company and is included in impairment of other assets on the consolidated statement of operations. On January 16, 2025, we terminated the Rebel Hosting Agreement and agreed to a settlement amount of $2.4 million payable to us in satisfaction of all obligations of the Rebel Hosting Agreement and it constitutes a final settlement of all amounts owed by either party of the Rebel Hosting Agreement. For the year ended December 31, 2025, we recorded a $0.3 million impairment for the portion of the settlement that was not received by us and is in default.

Management Agreement

In March 2025, we entered into a management services agreement with Simple Mining LLC (“Simple Mining”) to manage our Iowa Site for a term of 12 months, with automatic renewals for subsequent terms of 12 months unless terminated by either party with written notice 30 days prior to the expiration of the then current term.

At-the-Market Offering Program

On January 3, 2025, we entered into a sales agreement (the “AGP Agreement”) with A.G.P./Alliance Global Partners (the “Sales Agent”). In accordance with the terms of the AGP Agreement, the Company may offer and sell from time to time through or to the Sales Agent, as agent or principal, the Company's common shares having an aggregate offering price of up to $8.0 million (the “Placement Shares”). The AGP Agreement can be terminated by either party by giving two days written notice.

Neither us nor the Sales Agent are obligated to sell any Placement Shares pursuant to the AGP Agreement. Subject to the terms and conditions of the AGP Agreement, the Sales Agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of The Nasdaq Capital Market (“Nasdaq”), to sell the Placement Shares from time to time based upon our instructions, including any price, time or size limits or other customary parameters or conditions we may impose. Sales of the Placement Shares, if any, will be made on Nasdaq at market prices by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 of the Securities Act of 1933, as amended.

Environmental Issues

At our Iowa Site, we purchase electricity from the electrical grid. No significant pollution or other types of hazardous emissions result from our direct operations, and it is not anticipated that our operations will be materially affected by federal, state or local provisions concerning environmental controls. Our costs of complying with environmental, health and safety requirements have not historically been material.

Some local, state and federal policymakers have expressed concerns over the energy consumption of data centers, including those supporting bitcoin mining, HPC, AI workloads, and the ancillary effects on the environment from that energy consumption. These concerns generally relate to grid reliability. We carefully monitor existing and pending climate change legislation, regulation and international treaties or accords for any material effect on our business or markets that we serve, our operational results, our capital expenditures or our financial position.

Intellectual Property

We actively use specific hardware and software for our Bitcoin mining operations. We do not currently own, and do not have any current plans to seek, any patents in connection with our Bitcoin mining operations.

Competitive Conditions

Our business is highly competitive and operates 24 hours a day, seven days a week. The primary drivers of competition are demand for Bitcoin and the ability to execute miner deployments to generate the highest returns while incurring the lowest costs to mine, thereby achieving maximum efficiency.

Our competition in the Bitcoin mining space fluctuates due to a number of factors, including, but not limited to, the value of Bitcoin rewards for mining, the amount of network hashrate, and the price of Bitcoin. We anticipate that over the long-term there will be a significant increase in the number of Bitcoin miners attempting to enter into, and expand, their Bitcoin mining activities. Our main competitors generally include other Bitcoin mining companies, both publicly listed and private. As more Bitcoin miners enter the mining industry, we expect additional pressure on the industry, with greater competition for access to mining rewards, competition for power and high-quality industrial scale mining infrastructure which is in limited supply.

5

We rely on both owned mining facilities and hosting arrangements to conduct our business, and the availability and stability of these arrangements remain uncertain and highly competitive. Hosting arrangements, in particular, may be affected by changes in regulations across different countries, while owned facilities present additional risks, including operational challenges, infrastructure maintenance, and energy costs. Significant competition for suitable mining data centers is expected to persist, and government regulations—such as local permitting requirements—could further restrict the ability of both hosted and owned mining operations to begin or continue operating in certain locations. These factors could impact our ability to secure adequate infrastructure to support some of our hashrate and maintain profitable mining operations.
