Schedule 13G/Aregulatory
"filed an amendment to a Schedule 13G reporting beneficial ownership"
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
"Amount beneficially owned: 1,632,763"
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.
Investment Company Actregulatory
"investment companies registered under the Investment Company Act of 1940"
The Investment Company Act is a law that sets rules for businesses whose main activity is managing and selling pooled money, such as mutual funds and other investment funds. It matters to investors because it requires clear reporting, limits managers from putting their own interests ahead of clients, and mandates safekeeping and oversight of assets—similar to safety inspections and traffic rules that help keep shared vehicles reliable and trustworthy.
What stake does Dimensional Fund Advisors report in AMPY?
Dimensional reports beneficial ownership of 1,632,763 shares of AMPY, representing 4.0% of the class. The filing attributes the shares to funds managed or advised by Dimensional rather than to Dimensional as a direct owner.
Does Dimensional have voting power over the AMPY shares?
Yes. The filing shows sole voting power for 1,590,320 shares. Shared voting power is reported as zero. The shares are held by client Funds for which Dimensional acts as adviser or sub‑adviser.
Is Dimensional claiming beneficial ownership of the AMPY shares?
No. The filing states the shares are owned by the Funds and that Dimensional "disclaims beneficial ownership" of such securities, while acknowledging it may be deemed to possess voting or investment power in its advisory role.
When was the Schedule 13G/A for AMPY signed?
The Schedule 13G amendment is signed by the Global Chief Compliance Officer on 04/09/2026. The document also lists 03/31/2026 near the CUSIP, consistent with a quarter‑end reporting reference in the excerpt.
