The filing states Wellington has no sole voting or dispositive power over these shares.

What ownership stake does Wellington report in Apogee Therapeutics (APGE)?
Wellington reports beneficial ownership of 4,746,585 Apogee shares, or 8.66 % of the common stock. These shares are held for Wellington investment-advisory clients, giving Wellington group entities shared voting and dispositive power rather than direct, sole control over the position.
Which Wellington entities are reporting beneficial ownership in Apogee Therapeutics (APGE)?
The reporting entities are Wellington Management Group LLP, Wellington Group Holdings LLP, Wellington Investment Advisors Holdings LLP, and Wellington Management Company LLP. These related entities sit within Wellington’s ownership structure and oversee or control the investment advisers whose clients hold Apogee shares.
How much voting power does Wellington have over Apogee Therapeutics (APGE) shares?
The Wellington entities report no sole voting power and shared voting power over up to 4,341,936 Apogee shares. Voting authority arises through their role with investment-advisory clients that own the stock, rather than from direct ownership by Wellington itself.
Do Wellington entities directly own Apogee Therapeutics (APGE) shares or hold them for clients?
The securities are owned of record by clients of Wellington investment advisers, not directly by Wellington. Wellington Management Group LLP and its subsidiaries report beneficial ownership because they control advisers whose clients have rights to dividends and sale proceeds from the Apogee shares.
Is Wellington’s Apogee Therapeutics (APGE) stake intended to influence control of the company?
The certification states the shares were acquired and are held in the ordinary course of business, not to change or influence control. The position relates to investment-advisory activity for clients rather than participation in any control-seeking transaction.

No individual client is known to hold more than five percent of Apogee’s common stock. The filing explains that Apogee shares are held for multiple advisory clients, and none is identified as exceeding the five-percent ownership threshold in the class.
