FAQ

What insider transactions did Sphere 3D (ANY) report for its Chief Accounting Officer?

Sphere 3D’s Chief Accounting Officer reported RSU vesting into 16,250 common shares, followed by the sale of 6,250 shares at $1.61 each. The sale was specifically to cover the issuer’s tax withholding obligations tied to the RSU release on March 11, 2026.

Was the Sphere 3D (ANY) insider share sale a discretionary open-market transaction?

The 6,250-share sale at $1.61 was not a discretionary open-market trade. A footnote explains it was executed to satisfy the company’s tax withholding obligations stemming from vested RSUs, which makes it a mechanistic tax-related disposition rather than a signal-driven transaction.

How many Sphere 3D (ANY) shares does the insider hold after these transactions?

Following the reported transactions, the Chief Accounting Officer directly holds 12,384 shares of Sphere 3D common stock. This post-transaction balance already reflects the company’s 1-for-10 reverse stock split that became effective on February 9, 2026, as noted in the footnotes.

What RSU position does the Sphere 3D (ANY) officer retain after the Form 4 filing?

After the RSU conversion, the officer still holds 90,000 restricted stock units. Footnotes detail three grants: 5,000, 35,000, and 50,000 underlying shares, with quarterly vesting beginning June 1, 2026, and final vesting dates running through March 4, 2027.

How are the remaining Sphere 3D (ANY) RSUs scheduled to vest for the insider?

The RSUs vest in stages: 1,250 shares quarterly from June 1, 2026 to March 1, 2027 on a 5,000-share award, 5,000 shares quarterly from June 1, 2026 to December 1, 2027 on a 35,000-share award, and 50,000 shares vest fully on March 4, 2027.

Did Sphere 3D’s reverse stock split affect the insider share counts reported?

Yes. A footnote clarifies the common share balance has been adjusted for Sphere 3D’s 1-for-10 reverse stock split effective February 9, 2026. This means all common share amounts in the Form 4 are presented on a post-split basis for consistency.
