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.

Following the U.S. Supreme Court’s decision invalidating tariffs imposed under the International Emergency Economic Powers Act (IEEPA), litigation risk has entered a new phase. As previously noted on The D&O Diary, early lawsuits seeking recovery focused on companies that passed tariff costs on to consumers. A newly filed class action against Sony Interactive Entertainment suggests a second wave may now be emerging; one targeting companies for allegedly pursuing a “double recovery” by retaining both higher consumer prices and government tariff refunds.

In recent months, securities class action litigation patterns involving AI-related disclosures have emerged and developed, as has been documented on this site (most recently, for example, here). There has of course been a great deal of other kinds of AI-related litigation, including lawsuits involving intellectual property issues, privacy and data-collection concerns, discrimination and bias claims, and a variety of different kinds of tort allegations.

In a shareholder derivative lawsuit recently filed against the board of software firm Adobe, these two lines of AI-related litigation crossed; the plaintiff shareholder alleges that the defendants violated their board duties by knowingly permitting the company to train its artificial intelligence tools using material copyrighted by others and in a way that subjected the company to IP-related litigation. As discussed below, the new lawsuit illustrates how the broader range of AI-related litigation can translate into follow-on D&O claims, representing yet another area of AI-related D&O risk.

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.

One of the interesting features of the rise of AI has been the advent of “AI-and” businesses – that is, businesses whose strategy is to apply AI tools to traditional business models. When “AI-and” business results fall short, securities litigation has sometimes followed. In the latest example of this kind of litigation, earlier this week a plaintiff shareholder filed a securities suit against Upstart Holdings, a company whose business model involves applying AI tools to traditional credit rating and lending services, after the results from the company’s AI-updated credit rating tool disappointed investors. A copy of the new Upstart Holdings complaint can be found here.

One of the more interesting recent developments in the world of directors’ and officers’ liability and insurance has been the rise of collective actions and mass actions outside the U.S. Class actions are of course a well-established part of the litigation scene in the U.S., but at least traditionally class, mass, or collective actions have been rare outside the U.S. However, as discussed in a December 29, 2025, memo from the Labaton Keller Sucharow law firm entitled “Global Class Action Litigation: Causes, Effects and What’s Next” (here) a variety of changes in a number of jurisdictions has led to an increase in collective litigation outside the U.S., a development that could have important future implications for potential D&O liability.

In the months since the current Trump administration first announced the so-called “Liberation Day” tariffs, some companies have struggled to deal with the tariffs’ economic impacts, and in at least some cases, companies’ tariff-related problems have led to securities class action litigation (as discussed, most recently, for example, here). In the latest example of this phenomenon, earlier this week the social media company Pinterest was hit with a securities suit after the company announced that tariff-related headwinds had caused its business partners to cut back on advertising on the company’s site. A copy of the March 30, 2026, Pinterest complaint can be found here.

The rise of Artificial Intelligence (AI)-based tools and applications has also meant the rise in AI-related infrastructure, such as data centers and power generation support. And just as we have seen the rise of securities litigation relating to companies’ adoption of AI tools and processes, we have also seen securities suits relating to AI infrastructure development.

In the latest example of this kind of AI infrastructure-related litigation, on March 20, 2026, a plaintiff shareholder filed a securities class action lawsuit against the engine and power systems company Power Solutions International, alleging that the company’s new strategy of providing power generation solutions for AI data centers had fallen short of the company’s representations. A copy of the new complaint against Power Solutions can be found here.

In the wake of the February 20, 2026, U.S. Supreme Court decision to invalidate tariffs imposed under the current Administration’s use of the International Economic Emergency Powers Act (IEEPA), litigation has been filed by companies seeking tariff refunds and by shareholders alleging securities violations against a company whose operations and financial results were impaired by “tariff headwinds.”   A new category of litigation is also beginning to appear: consumer class actions alleging that companies improperly passed tariff costs on to customers.

As detailed in prior posts on this site (here and here), turbulence in the private credit markets has roiled the financial marketplace. Collapses (and related scandals) involving high profile private credit borrowers – including Tricolor and First Brands– have led to bankruptcies, civil lawsuits, and criminal indictments. The disruption in the private credit markets has also recently led to securities class action lawsuits involving private credit lenders. In the most recent example of this phenomenon, late last week a plaintiff shareholder filed a securities class action lawsuit against private credit lender Hercules Capital, after a short seller published a report suggesting that the company had misrepresented its borrower due diligence processes. A copy of the March 20, 2026, lawsuit can be found here.
