Sleeping on Your Stock: A $25 Million Lesson

Alon Kapen Farrell Fritz, P.C. + Follow Contact LinkedIn Facebook X ;) Embed A recent March 20, 2026 letter decision from the Delaware Court of Chancery in Gary T. Turner v. Lam Research Corporation is a stark illustration of how unforgiving Delaware courts can be when stockholders sit on their rights. For venture-backed companies and their stockholders, the case underscores a simple but critical point: stock ownership rights are only as durable as the diligence used to monitor and enforce them.

Background: Forgotten Shares, Extraordinary Value

Gary Turner, an early employee of Lam Research Corporation, a Nasdaq listed company, alleged that he received 2,375 shares of common stock as a bonus in 1988. After stock splits, those shares would have grown to over 100,000 shares and worth approximately $25 million at recent trading prices.

There was just one problem: When Turner attempted to sell the shares decades later, the company’s transfer agent had no record of his ownership. Historical records indicated that the shares had been marked “lost” around the time of a 1989 merger.

Turner sued in the Court of Chancery seeking, among other things, a declaration of stock ownership under Section 168 of the Delaware General Corporation Law, as well as claims for conversion and breach of contract.

The Holding: Time Bar Trumps Merit

Chancellor McCormick granted the company’s motion to dismiss in full, holding that all claims were barred by laches.

The analytical structure is familiar but applied here with unusual force. Each claim was subject to a three-year statute of limitations; claims filed outside that period are presumptively untimely in equity; and absent a viable tolling doctrine, laches will bar the claims, even at the pleading stage.

The court found that the claims accrued, at the latest, when the company treated the shares as “lost” in 1989, more than three decades before suit was filed.

Inquiry Notice Does the Work

The key doctrinal move was the court’s reliance on “ inquiry notice” to defeat tolling.

Delaware recognizes limited tolling doctrines – fraudulent concealment, inherently unknowable injury, and equitable tolling – but all of them end once a plaintiff is on “inquiry notice” of a potential claim. The standard is objective: whether a person of ordinary intelligence and prudence would have been prompted to investigate.

Here, two facts were dispositive.  First, Turner never received stockholder communications from a public company that regularly distributed proxy materials.  Second, Turner never received dividends, despite the company paying them for years.

Either fact alone, the court held, would have put a reasonable stockholder on inquiry notice that something was amiss. Together, they made the case straightforward. As the court emphasized, confirming ownership status was “at most, a phone call or mouse click away.”

No Sympathy for Passive Holders

The equities here were not subtle. The plaintiff stood to lose roughly $25 million in claimed value. The court acknowledged the harshness of the outcome but leaned into the policy rationale underlying laches: evidentiary decay. After decades, key witnesses may be unavailable.  Records may be incomplete or ambiguous. And corporate actions (like the “lost securities” designation) are difficult to reconstruct with confidence.

In those circumstances, Delaware courts will not stretch equitable doctrines to revive stale claims. The opinion closes with a pointed observation: if laches does not bar claims on these facts, it is difficult to imagine when it would.

Why This Matters for Venture-Backed Companies

While Turner arises in the public-company context, the implications translate directly to private and venture-backed companies and their stockholders.

The first implication is that good cap table hygiene is not optional.  Early-stage equity grants can become economically significant over time. Companies should ensure that historical issuances, cancellations and corporate actions are well-documented and reconciled, particularly around mergers or re-domicile transactions.

Second, stockholders must act like stockholders. **** Investors and employees cannot treat equity as a “set it and forget it” asset. Failure to receive basic indicia of ownership – annual meeting notices, cap table updates, written consents and other communications – should trigger immediate inquiry.

Third,  transfer agent and recordkeeping practices matter. **** This case turned in part on a “lost securities” designation dating back to a corporate transaction. For later-stage companies, especially those approaching liquidity, coordination with transfer agents and maintenance of accurate ownership records are critical risk mitigants.

And fourth, laches is a real defense. **** Delaware courts are increasingly willing to dispose of stale equity claims early, particularly where the complaint itself establishes inquiry notice. This has implications for litigation strategy on both sides: plaintiffs must anticipate timeliness challenges, and defendants should scrutinize delay-based defenses aggressively.

Bottom Line

Turner v. Lam Research is a cautionary tale about the intersection of stock ownership and equitable doctrine. Delaware will enforce stockholder rights, but only for those who exercise them with reasonable diligence. In a venture context, where early equity can become extraordinarily valuable, the cost of inattention can be measured not just in legal defeat, but in life-changing economic loss.
