Rhea-AI Filing Summary

Mercer International Inc.’s largest disclosed shareholder group, led by Peter and Charles Kellogg and affiliated entities, filed Amendment No. 12 updating their ownership of common stock. The group may be deemed to beneficially own 26,950,672 Shares, or 40.25% of the 66,982,506 Shares outstanding.

Goose Creek Capital, Inc. is attributed 18,220,000 Shares, IAT Reinsurance Company Ltd. 11,920,000 Shares, and Harco National Insurance Company 6,217,000 Shares, all reported with shared voting and dispositive power. Peter Kellogg has sole voting and dispositive power over 8,730,672 Shares and shared power over the 18,220,000 Shares attributed to Goose Creek.

The amendment reflects Peter Kellogg’s sale of 100,005 Class A Voting Preferred shares of Goose Creek to Charles Kellogg, which closed on January 19, 2021, giving Charles indirect voting control over Goose Creek’s holdings. However, an oral family agreement grants Peter Kellogg exclusive authority over voting, holding, acquiring, and disposing of all family-controlled Shares. On June 1, 2026, Peter Kellogg also purchased 419,743 Shares in open market transactions at prices between $0.8984 and $0.91 per Share.

Filing Explained

Future buying, selling, or discussions remain conditional possibilities; this amendment mainly clarifies the ownership reporting chain.

Signed on July 31, 2026, this completed amendment adds IAT Reinsurance Company Ltd., IAT Insurance Group, Inc., and Harco National Insurance Company as named reporting persons and clarifies the entities in the group's beneficial-ownership reporting chain.

Schedules 13D disclose ownership above 5%, while amendments track changes in stake or intent. Here, the filing says the added entities' shares were already included in prior aggregate ownership figures, so the disclosed change is to reporting attribution rather than a newly created ownership position.

The reporting persons say they may later buy or sell shares or discuss the issuer's business with management or the board, depending on stated factors, but describe those actions as possible future steps rather than current commitments.

beneficially own financial
"may be deemed to beneficially own in the aggregate 26,950,672 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.
sole voting power financial
"Number of Shares Beneficially Owned... Sole Voting Power 8,730,672.00"
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.
dispositive power financial
"Sole Dispositive Power 8,730,672.00 10 | Shared Dispositive Power 18,220,000.00"
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.
Joint Filing Agreement regulatory
"entered into a Joint Filing Agreement in connection with the filing"
pecuniary interest financial
"disclaims beneficial ownership of such Shares except to the extent of his pecuniary interest"
Schedule 13G regulatory
"previously filed a statement on Schedule 13G to report the acquisition"
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.
