Insights

Equity ownership & governance analyst

Large disclosed stake (45.1%) with conditional warrant; neutral impact.

The reporting group lists beneficial ownership of 56,806,080 NovaBay common shares, or 45.1%, with shared voting and dispositive power and no sole power. The stake is driven by convertible preferred holdings: Series D (up to 35,306,080 shares) and Series E (up to 21,500,000 shares). The baseline common shares outstanding were 6,010,749 as of October 1, 2025.

Item 6 adds a pre-funded warrant for 2,702,703 shares, which is not exercisable until January 1, 2026 and not exercisable in its entirety until stockholder approval of the share issuance. These conditions gate any additional voting or economic exposure from the warrant until satisfied.

Ownership disclosures can influence control dynamics, but actual impact depends on conversion and exercise decisions under the stated limits and approvals. Subsequent filings may provide updates if conversions or approvals occur.
