SCHEDULE 13D/A

Rhea-AI Filing Summary

Granite Ridge Resources, Inc. common stock is the subject of an amended Schedule 13D filed by a group of Grey Rock–affiliated funds and individuals. The Filing Parties were originally issued 118,740,242 shares of common stock and, after a series of distributions and sales, now report holding an aggregate of 65,869,219 shares. This amount represents 49.9% of the 131,895,990 shares outstanding as of June 15, 2026.

These shares are largely coordinated under a Stockholder Voting Agreement among the Grey Rock fund GPs and key individuals, giving the Voting Agreement Parties control over 65,869,219 shares, or 50.3% of the shares entitled to vote. Fund III intends to begin pro rata distributions of Granite Ridge shares to its limited partners in the third quarter of 2026. Fund II entities have fully distributed their positions and now report 0 shares. Individual participants report direct holdings including Matthew Miller with 1,349,735 shares, Thaddeus Darden with 403,145 shares, Griffin Perry with 1,147,877 shares, and Kirk Lazarine with 1,051,997 shares, alongside 6,650,497 shares held by Grey Rock Energy Fund II-C, LLC.

Filing Explained

Fund III’s distributions are prospective, while the voting proxy and transfer limits remain operative under the current agreement.

The amendment states that the Stockholder Voting Agreement continues indefinitely, while allowing termination on 30 days' notice from parties holding a majority of the covered shares. Under that agreement, covered holders have irrevocably and unconditionally agreed to vote their shares, and they generally cannot transfer them without GREP GP III's consent during the agreement's term.

The filing describes the planned Fund III distributions as transfers of existing shares to limited partners, rather than as a company issuance. The next named milestone is Fund III's stated start of distributions in the third quarter of 2026.

Stockholder Voting Agreement regulatory

"entered into a Stockholder Voting Agreement (the "Voting Agreement")."

beneficial ownership financial

"As a result of the Voting Agreement described in Item 4, GREP GP III has beneficial ownership"

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.

pro rata financial

"distributed 5,246,604 shares of Common Stock pro rata to the partners of Fund II-A"

Pro rata means dividing or distributing something proportionally based on a specific factor, such as ownership or contribution. For example, if an investor owns 10% of a company, they would receive 10% of any dividends or benefits allocated. This approach ensures everyone gets their fair share relative to their stake or input, helping investors understand how benefits, costs, or responsibilities are fairly shared.

restricted stock financial

"pursuant to an award of restricted stock granted to each of the Company's director"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

Registration Rights and Lock-Up Agreement regulatory

"Registration Rights and Lock-Up Agreement, dated October 24, 2022, among the Company"

Underwriting Agreement financial

"Underwriting Agreement, dated September 12, 2023, among the Company, the selling stockholders"

An underwriting agreement is a contract where a company selling new stocks or bonds hires financial firms to buy those securities and resell them to investors. It matters because the agreement sets the offering price, number of securities, fees and which party bears the risk if sales fall short—think of it as a promise that the sale will happen and a roadmap investors can use to understand how the new securities reach the market.
