Insights

Corporate Governance Expert

TL;DR: Insider's ownership in Star was reduced to zero through a merger exchange; RSUs were assumed and converted with original vesting preserved.

The Form 4 discloses that Jeff Eberwein, a named executive and director, disposed of his entire direct holdings in both Star common stock and Star Series A preferred stock as a direct result of the Merger Agreement with Hudson Global, Inc. The filing is procedural and reflects corporate control change mechanics rather than open-market selling. The conversion of restricted stock units into Hudson instruments preserves vesting schedules, indicating continuity of compensation treatment post-closing.

M&A Specialist

TL;DR: Material ownership transfer tied to merger: significant share exchanges (820,374 common; 1,182,414 preferred) occurred under the defined exchange ratios.

The transaction arises from the Merger Agreement dated May 21, 2025, under which Star shareholders received .23 shares of Hudson common for each Star common and one Hudson Series A Preferred for each Star preferred. The reported disposals reflect conversion mechanics, not open-market dispositions, and show the scale of insider equity moved into Hudson securities. This is a material corporate event affecting shareholder registers and ownership percentages.
