Context

• This is an institutional disposition by a >10% shareholder (Advent), not an individual executive buy/sell. Transaction code "U" indicates the sale was in connection with a change in control event — see Exhibit 99.1 and related filings for details on that change in control. Institutional block sales tied to M&A or control transactions are different from routine insider sales and may reflect deal-structure mechanics rather than trading sentiment.
