The D&O Diary has been chronicling how securities plaintiffs continue to expand litigation theories beyond traditional “AI-washing” claims. The recent securities class action against data protection company Commvault Systems, Inc. demonstrates how AI hype and strategy can become entangled with traditional securities claims, even when actual AI integration is not the central issue of the lawsuit.

For several years, cybersecurity has been a perennial D&O liability issue. Although there has never quite been the volume of cybersecurity-related D&O litigation that some anticipated, cybersecurity-related D&O claims do continue to arise. In the latest example, last week a plaintiff shareholder filed a securities suit against cloud data storage company Snowflake, alleging, among many other things, that the company failed to disclose shortcomings in its customer data security arrangements that allegedly allowed key customers to experience a data breach. There are a number of noteworthy aspects of this new complaint and its cybersecurity-related allegations, as discussed below. A copy of the plaintiff’s complaint can be found here.

It is a well-established fact that securities class action lawsuits rarely go to trial. In most cases, the lawsuits are either dismissed or settled. However, there has been an interesting recent uptick in the number of securities suits going all the way to a jury verdict. In the latest example of this development, on May 14, 2026, a federal court jury entered a defense verdict following trial in the long-running ExxonMobil securities class action lawsuit. As discussed below, this verdict is the latest of several post-trial verdicts entered in securities suits this year. A May 14, 2026, Law360 article about the verdict can be found here.

The recent securities and derivative litigation involving e.l.f. Beauty reflects a familiar D&O liability pattern: a high-growth narrative challenged by operational headwinds, followed by securities litigation and a derivative action. While e.l.f. and its D&Os achieved meaningful success at the motion to dismiss stage, the survival of certain securities claims and a recently filed a derivative complaint in Delaware highlights the potential of prolonged D&O exposure.

According to industry reports, education technology companies experienced unprecedented demand during COVID‑19, fueled by remote learning mandates and significant public investment in digital infrastructure. School districts rapidly deployed laptops, software platforms, and immersive learning tools while students were learning remotely. However, now that classrooms have largely returned to in‑person instruction, a growing backlash against ed‑tech has begun to emerge.  In the last month, both the New York Times and Wall Street Journal have reported on the backlash from educators and parents, as well as study results showing the deteriorating effect of technology use in classrooms.

This recent reporting has coincided with certain ed‑tech companies confronting tightening capital markets, operational challenges, and increasing scrutiny from investors and regulators. A complaint filed against zSpace, Inc (zSpace) and its directors and officers on April 23, 2026  (zSpace SCA), may demonstrate how these converging dynamics are now beginning to manifest in securities litigation.  The following will discuss the zSpace SCA allegations, the company’s purported financial pressures, and potential D&O exposure for companies in the ed‑tech industry.

In a rare trial in a securities class action lawsuit, a federal jury has ruled that hedge fund Armistice Capital and certain of its executives had not, as the plaintiffs alleged, committed insider trading or engaged in a pump-and-dump scheme in selling over $200 million in vaccine company Vaxart stock during the COVID-19 pandemic. The jury specifically held that the plaintiffs had not proven that the defendants had engaged in a scheme to defraud and had not proven their insider trading allegations.

Peloton Interactive, Inc. (Peloton) has faced well-publicized operational and reputational challenges over the past several years. The company’s trajectory, from pandemic-era growth darling to post-pandemic recalibration and product safety scrutiny, has resulted in securities litigation. As previously discussed on the D&O Diary, Peloton successfully defeated a COVID-19-related securities suit at the pleading stage. More recently, the company faced a second securities class action tied to alleged product defects in its flagship bike (Peloton SCA). In a March 31, 2026, decision, the United States District Court for the Eastern District of New York granted Peloton’s motion to dismiss, rejecting plaintiff shareholders’ attempt to convert operational challenges into actionable securities fraud.

In February, I noted an emerging securities litigation trend involving pump-and-dump schemes characterized by thin public float, retail investor participation, and the amplifying effects of social media. Three subsequent pump-and-dump securities filings in February and March 2026, along with a recent federal court ruling involving social media platform liability, provide further evidence that these risks may be accelerating. Taken together, these developments have important implications for D&O liability exposure and for underwriters evaluating risks associated with low-float issuers and companies whose securities trading activity may be influenced by online promotional activity.
