[SCHEDULE 13G/A] Energy Recovery, Inc. Amended Passive Investment Disclosure
Ameriprise reports 1.3% stake in Energy Recovery
Ameriprise Financial, Inc. and related Ameriprise entities report beneficial ownership of Energy Recovery, Inc. common stock on a Schedule 13G/A (Amendment No. 5).
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Ameriprise Financial, Inc. and related Ameriprise entities report beneficial ownership of Energy Recovery, Inc. common stock on a Schedule 13G/A (Amendment No. 5). Ameriprise Financial, Inc. has shared voting power over 678,251 shares and shared dispositive power over 679,236 shares, representing 1.3% of the common stock.
The filing states that Ameriprise, as parent of the other Ameriprise entities, may be deemed to beneficially own the shares reported by those entities, while each Ameriprise entity disclaims beneficial ownership. The group reports ownership of 5 percent or less of the class.
"AFI, as the parent company of the other Ameriprise Entities, may be deemed to beneficially own the shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
shared voting powerfinancial
"6 | Shared Voting Power 678,251.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

Schedule 13Gregulatory
"Each of the Ameriprise Entities disclaims beneficial ownership of any shares reported on this Schedule."
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.
