Texas Court Dismisses Coinbase Shareholder Suit Over Missing Board Demand

Texas Business Court tosses derivative claim against Coinbase

On October 2, 2026, a Texas Business Court dismissed a shareholder lawsuit against Coinbase because the plaintiff had not submitted a required written demand to the company's board before filing the case. The dismissal was without prejudice, meaning the plaintiff can refile if they comply with Texas procedure. The court did not rule on whether any misconduct occurred.

The suit was a derivative action, which allows a shareholder to bring a claim on behalf of a corporation rather than for themselves. The claim belongs to the company, and the shareholder asks the court to exercise authority normally held by the board. In this case, the first legal hurdle was whether the shareholder had permission to pursue the claim at all, not whether the alleged wrongdoing happened.

Key numbers and timeline

• The shareholder, Gary Guillaume, filed his suit on April 16, 2026.
• The alleged misconduct dates from April 14, 2021, to June 5, 2023.
• Coinbase was incorporated in Delaware during that earlier period.
• Coinbase's move to Texas became effective on December 15, 2025, several months before the suit was filed.
• The conversion was approved by shareholders linked to the company's founders who held 78.40% of voting power at the October 2025 record date.
• Judge Andrea K. Bouressa signed the October 2 order.
• On October 9, Coinbase CEO Brian Armstrong publicly praised the ruling and thanked Texas Governor Greg Abbott.

Two states' laws applied to the same case

The court used Delaware law to assess the underlying claims because they arose while Coinbase was a Delaware company. The court assumed, without formally deciding, that Delaware law governed those claims.

For the separate question of whether the shareholder had the right to bring the suit in the first place, the court applied Texas law. The opinion reasoned that a shareholder does not automatically gain a permanent personal right to sue on the company's behalf just because a corporate claim arises under one state's law. When the shareholder later exercises that authority, the rules of the state where the company is currently incorporated govern.

Why the written demand mattered

Under the Delaware framework described in the opinion, a shareholder bringing a derivative claim can either make a demand to the board or argue that demanding action would be futile. Futility requires specific allegations about individual directors, including whether they received a material personal benefit, face a substantial likelihood of legal liability, or lack independence from someone who benefited or faces liability. At least half of the relevant board members must meet this test.

Guillaume did not make a pre-suit demand and instead relied on futility allegations.

For a public company in Texas, the rules require a particularized written demand that identifies the disputed conduct and requests suitable corporate action. The opinion described a standard 90-day waiting period after demand, with derivative proceedings allowed from the 91st day. A corporate rejection of the demand or a showing of irreparable harm to the corporation can shorten the wait, but both exceptions leave the written demand requirement in place.

The court found that Guillaume's futility allegations could not substitute for the written request Texas required. The missing demand was enough to end the action before the court reached the merits of the case.

What the conversion disclosures did and did not promise

Guillaume argued that Coinbase's own conversion disclosures preserved eligible shareholders' ability to bring derivative claims about earlier conduct, subject to continued ownership.

The court took a narrower view. It said those disclosures did not promise that Delaware law would continue to govern shareholder authority after the conversion.

Why this matters for other shareholders

The ruling shows that when a company moves its incorporation from one state to another, the legal rules governing shareholders' ability to challenge past board decisions can change. In this case, Coinbase's December 2025 conversion affected the route for challenging alleged conduct dating back to 2021.

The opinion also has implications beyond this single case. By emphasizing that reincorporation can alter the procedural path for derivative suits, the ruling gives companies another consideration when deciding where to incorporate. Coinbase's CEO has framed the outcome as encouraging for more companies to incorporate in Texas.

What happens next

Because the dismissal was without prejudice, the shareholder can refile the suit if they comply with Texas's written demand requirement. No further steps were announced in the source material.
