Magnachip Semiconductor reports an amendment to a Schedule 13G disclosing that Toro 18 Holdings LLC beneficially owned 1,500,135 shares of common stock as of the close of business on March 20, 2026. That stake represented approximately 4.1% of the class based on 36,440,854 shares outstanding as of March 13, 2026.
The filing states that Immersion Corporation (the sole member of Toro 18), William C. Martin (Chief Strategy Officer of Toro 18) and Eric Singer (President and CEO of Toro 18) may be deemed to beneficially own the same 1,500,135 shares through shared voting and dispositive power. Each of the Reporting Persons disclaims beneficial ownership of shares held by another Reporting Person.

Insights
Toro 18 holds a ~4.1% stake reported via a Schedule 13G amendment.
The filing lists 1,500,135 shares beneficially owned by Toro 18 with shared voting and dispositive power attributed to Immersion, William C. Martin, and Eric Singer. The percentage is calculated from 36,440,854 shares outstanding as of March 13, 2026.
Beneficial‑ownership disclaimers are included; this preserves separate legal attribution. Subsequent filings could clarify whether the position is passive or part of coordinated group activity.
The position represents a meaningful minority stake without sole control.
The Schedule 13G/A shows shared voting and shared dispositive power of 1,500,135 shares, implying coordinated visibility but not sole voting authority. The filing references prior exhibits filed on January 2, 2025.
Market impact depends on whether Reporting Persons maintain passive investor status or later file a Schedule 13D; future amendments would change the public disclosure and governance implications.
