Insights

Governance and ownership structure analyst

Filing updates a large, coordinated shareholder group holding 18.1% of Tredegar.

This amendment details how the Gottwald family members and a related charitable lead annuity trust collectively beneficially own 6,349,496 Tredegar shares, or 18.1% of the company’s common stock. It clarifies individual and shared voting and dispositive powers.

The filing follows an event dated May 15, 2026 and notes that Exhibit 99.2 lists recent CLAT share sales on the New York Stock Exchange. Actual market impact depends on the scale and pace of those sales, which are not quantified here.

Future ownership disclosures in Schedule 13D/A updates or other company filings may show whether this group’s overall percentage interest or control profile changes from the current level based on 35,016,819 shares outstanding as of March 31, 2026.

Schedule 13D regulatory

"Amendment No. 18 amends and supplements Amendment Nos. 1 through 17 to the statement on initially filed on August 15, 1989"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

beneficially owned financial

"11Aggregate amount beneficially owned by each reporting person 5,997,453.00"

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.

Sole Voting Power financial

"Number of Shares Beneficially Owned by Each Reporting Person With: | 7 | Sole Voting Power 1,917,639.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

Shared Voting Power financial

"8 | Shared Voting Power 4,079,814.00"

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.

dispositive power financial

"9 | Sole Dispositive Power 1,917,639.00 10 | Shared Dispositive Power 4,079,814.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
