Insights

Securities Analyst

TL;DR Large insider dispositions were reported on 08/26/2025, including a 22.5 million-share indirect disposal, which is material to share supply.

The filing documents material share disposals by Thomas H. Lee Advisors, LLC and multiple directors. The 22,525,103-share indirect disposal is significant in absolute terms and is reported as reducing beneficial ownership to zero for that position. The submission lacks price information and detailed footnote text, which limits valuation impact analysis. Because the transactions are sizable, they could be relevant to market liquidity and investor perception, but price and proceeds data are needed to assess realized value and tax/timing considerations.

Corporate Governance Expert

TL;DR Multiple directors and an adviser filed dispositions; exhibits referenced for footnotes and joint-filer details are required for full context.

The Form 4 is filed by a group of reporting persons including directors and Thomas H. Lee Advisors, LLC and is split into multiple filings due to the number of filers. The report references Exhibit 99.1 for footnotes and Exhibit 99.2 for joint filer information, indicating further disclosure outside this document. Without those exhibits, it is unclear whether dispositions follow pre-arranged plans or other governance-approved mechanisms. Additional exhibit details would clarify compliance and intent.
