Insights
Wellington discloses a >7% passive stake in CarGurus.
Wellington-affiliated entities report 7.34% beneficial ownership through client accounts, with 5,945,970 shares listing as shared dispositive power and 3,420,310 as shared voting power. The filing is a passive ownership disclosure under Schedule 13G/A.
The economic exposure derives from client accounts managed by the named Wellington advisers; cash-flow treatment and which specific clients hold >5% are not identified in the excerpt. Subsequent filings would name any clients exceeding 5% if known.
Filing aligns with Schedule 13G/A reporting conventions and parent/subsidiary disclosure.
The cover responses list parent and subsidiary relationships among Wellington entities and identify the investment advisers that manage the record holders. The filing notes that no client is known to hold more than 5% of the class.
Signatures dated 05/15/2026 complete the amendment. The disclosure preserves qualifiers about record ownership by clients and classifies several entities as holding companies or investment advisers per the schedule.

"Responses identify the filing as a Schedule 13G/A ownership disclosure"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
Beneficial ownershipfinancial
"Item 4 states the amount 'beneficially owned' and the 'percent of class'"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Shared dispositive powerregulatory
"Cover pages list 'Shared Dispositive Power 5,945,970.00' for Wellington entities"
Investment adviser (IA)financial
"The filing lists Wellington Management Company LLP and other firms as the 'Wellington Investment Advisers'"
An investment adviser (IA) is a person or firm that provides personalized guidance on buying, selling, or holding investments and often manages client portfolios for a fee. Investors should care because an IA has a legal duty to act in the client's best interest—think of them as a navigator who plans and steers your financial journey—so their advice, fee structure and potential conflicts can directly affect returns and financial risk.
