Insights
Stake disclosure signals a sizeable passive ownership position but includes standard disclaimers.
The schedule shows 3,900,656 shares (9.1%) reported for RPD Fund Management LLC and Mr. Ahmet H. Okumus, and 3,225,956 shares (7.5%) for two RPD entities.
Filing language includes a disclaimer of beneficial ownership except for pecuniary interest and an Exhibit B for control‑person identification; governance implications depend on whether these holdings are passive or seek active influence.
This Schedule 13G documents substantial ownership percentages that may affect float and potential shareholder voting blocks.
The reported positions reach 9.1% and 7.5% interrelatedly, with shared voting and dispositive power listed rather than sole powers. The report is dated 02/24/2026.
Practical impact depends on whether the holdings remain passive; subsequent filings could clarify intent or changes in voting/disposition authority.
