Schedule 13Gregulatory
"Schedule 13G reporting beneficial ownership positions in Common Stock"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
Sole Dispositive Powerregulatory
"Sole Dispositive Power 3,159,710.00 shown on cover responses"
Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
Beneficially ownedfinancial
"Amount beneficially owned: See the response(s) to Item 9 on the attached cover page"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
Investment adviserfinancial
"ACIM serves as investment adviser and acts for advised clients"
An investment adviser is a person or firm that professionally manages money and gives recommendations about buying, selling, or holding investments. Like a financial coach or guide, they have a legal duty to act in a client's best financial interest, so their advice, fees and potential conflicts can directly affect returns and risk — making their role important for investors who want informed, accountable help with portfolios.
American Century reports holdings of 3,335,013 shares (5.5%). The filing shows ACIM, ACC and Stowers Institute each report 3,335,013 shares representing 5.5% of United Natural Foods, Inc. common stock in a joint Schedule 13G.
How many UNFI shares does American Century ETF Trust hold?

Are these holdings held on behalf of clients or the firms themselves?
The filing states some holdings are on behalf of clients advised by ACIM. Item 6 explains ACIM serves investment advisory clients who may have the right to dividends or proceeds; the schedule is a joint filing by related entities.
When were these ownership disclosures signed?
The joint Schedule 13G signatures are dated May 1, 2026. The filing is executed by authorized signers including John Pak for American Century entities and Joselyn Verschelden for Stowers Institute on 05/01/2026.
