Politan Capital Management Exits Masimo Corp Position Following Merger Consummation

Politan Capital Management LP, along with its affiliates and Managing Member Quentin Koffey, filed Amendment No. 17 to their Schedule 13D on June 11, 2026, reporting the full exit of their position in Masimo Corporation (MASI). The liquidation of their holdings resulted from the consummation of a merger on June 10, 2026, in which Masimo Corporation became a wholly owned subsidiary of a parent entity. At the effective time of the merger, each share of common stock was cancelled and converted into the right to receive $180.00 in cash per share. Consequently, the 4,590,873 shares previously held by the reporting persons were converted into cash consideration. Additionally, 1,119 restricted share units held by Mr. Koffey in his capacity as a non-employee director were also cancelled and converted into the right to receive the same per-share merger consideration. Following these transactions, the reporting persons no longer beneficially own any shares of Masimo Corporation common stock, representing a 0.0% ownership stake.
