EXPLANATORY NOTE

This Registration Statement on Form S-8 (this “Registration Statement”) is being filed by Sphere 3D Corp. (the “Company” or the “Registrant”), to register for issuance 500,000 Common Shares reserved for issuance pursuant to a restricted stock unit award granted to Joel Block on June 7, 2026, effective upon the filing of this Registration Statement, to induce him to accept employment as the Chief Executive Officer of the Company (the “Inducement Grant”).

The Inducement Grant is generally subject to the terms and conditions of the Company’s 2025 Performance Incentive Plan, as amended (the “2025 Plan”), but is not charged to the 2025 Plan’s share reserve.

The Inducement Grant was granted as an inducement material to Mr. Block entering into employment with the Company in accordance with the “inducement” grant exception under Nasdaq Listing Rule 5635(c)(4). The Inducement Grant is unvested and unsettled as of the date of this Registration Statement.
