In Sneed v. Talphera, Inc., 2025 WL 2406424 (9th Cir. Aug. 20, 2025), the United States Court of Appeals for the Ninth Circuit affirmed the dismissal of a securities fraud suit against Talphera, Inc. (formerly AcelRx Pharmaceuticals; the “Company”) and two top executives, holding that a company slogan used in investor presentations — “Tongue and Done” — was not misleading to reasonable investors, especially in light of accompanying disclosures. This opinion clarifies the interplay between marketing materials, context and the reasonable investor standard for reliance and materiality in claims under Section 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”), 15 U.S.C. § 78j(b), and Securities and Exchange Commission Rule 10b-5, 17 C.F.R. § 240.10b-5.Continue Reading Ninth Circuit Affirms Dismissal of Securities Fraud Suit: Marketing Slogan Alone Not Actionable Under Section 10(b) and Rule 10b-5

The United States Court of Appeals for the Fourth Circuit recently joined a growing consensus among federal appellate courts: short-seller reports, without more, rarely suffice to plead loss causation under the federal securities laws. In Defeo v. IonQ, Inc., 2025 U.S. App. LEXIS 8216, ___ F.4th ___ (4th Cir. Apr. 8, 2025), the Court held that a report by activist short-seller Scorpion Capital — which coincided with a significant stock price drop — did not constitute a corrective disclosure revealing previously concealed fraud to the market. The opinion aligns the Fourth Circuit with decisions from the Ninth Circuit, which have similarly found that loss causation cannot rest on short-seller publications that are speculative, anonymously sourced and heavily disclaimed.Continue Reading Fourth Circuit Rejects the Use of Short-Seller Report as a Basis for Satisfying Loss Causation Element in Securities Fraud Action

In Max Royal LLC v. Atieva, Inc., No. 23-16049, 2024 U.S. App. LEXIS 19910 (9th Cir. Aug. 8, 2024), the United States Court of Appeals for the Ninth Circuit affirmed the dismissal of a securities class action brought by investors who purchased shares of the special purpose acquisition company Churchill Capital Corporation IV (“CCIV”) in early 2021 before it merged with Atieva, Inc. d/b/a Lucid Motors (“Lucid”) in July 2021. The three-judge panel held that purchasers of a security of an acquiring company do not have standing under Section 10(b) of the Securities Exchange Act of 1934, 15 U.S.C. § 78j(b), to sue the target company for alleged misstatements by the target company made prior to the merger between the two companies. The Court’s decision provides protection to target company executives speaking to the press about their company’s forecasts and capabilities prior to acquisition by tightening the standing requirements for pre-acquisition SPAC investor plaintiffs.Continue Reading Ninth Circuit Applies Birnbaum Rule to Affirm Dismissal of Claims by SPAC Investors Asserted Against Target Company Executives for Pre-Merger Statements

In Securities and Exchange Commission v. Jarkesy, No. 22-859, 2024 WL 3187811 (U.S. June 27, 2024), the United Stated Supreme Court (Roberts, C.J.) held that when the Securities and Exchange Commission (“SEC”) seeks civil penalties against a defendant for securities fraud, the Seventh Amendment of the United States Constitution entitles the defendant to a trial by jury. This decision was based upon the Court’s interpretation that the SEC’s antifraud provisions replicate common law fraud, and thus actions for violations of these provisions implicate the Seventh Amendment right. The Court determined that the “public rights” exception, which allows certain matters to be resolved outside of Article III courts without a jury, does not apply in this context because the action does not fall within the distinctive areas involving governmental prerogatives traditionally resolved without Article III adjudication. This ruling curtails the SEC’s authority to impose penalties for fraud, and could potentially affect the enforcement capabilities of agencies enforcing federal law.Continue Reading Supreme Court Limits SEC’s Enforcement Power to Penalize Fraud

In Macquarie Infrastructure Corp. v. Moab Partners, No. 22-1165, 2024 WL 1588706 (U.S. Apr. 12, 2024) (“MIC”), the United States Supreme Court (Sotomayor, J.) held unanimously that “pure omissions” in a Securities and Exchange Commission (“SEC”) filing do not support liability under SEC Rule 10b-5(b). The Court ruled that the failure to make a required disclosure can give rise to a Rule 10b-5(b) claim only if the non-disclosure renders affirmative “statements made” misleading. Put differently, if a company elects to speak, it must tell the whole truth (or at least “information necessary to ensure that the [affirmative] statements made are clear and complete”); but a company’s silence on an issue is not securities fraud under Rule 10b-5(b), even if the company is otherwise duty-bound to disclose.Continue Reading Supreme Court Holds “Pure Omissions” Are Not Actionable Under Rule 10b-5(b)

In Roth v. Foris Ventures, LLC, Nos. 22-16632, 22-16633, 2023 U.S. App. LEXIS 30081 (9th Cir. Nov. 13, 2023), the United States Court of Appeals for the Ninth Circuit partially reversed the dismissal of a shareholder derivative suit seeking to recover disgorgement of short-swing profits under Section 16(b) of the Securities Exchange Act of 1934, 15 U.S.C. § 78p(b). The three-judge panel held that the district court erred in holding that the company’s board was required to approve the stock sale transactions for the specific purpose of exempting it from Section 16(b) liability pursuant to Securities and Exchange Commission (“SEC”) Rule 16b-3(d)(1). The Court’s decision provides a board of directors with more latitude to approve securities transactions by Section 16 reporting persons without risk of liability under the short-swing profits rule.Continue Reading Ninth Circuit Provides Guidance on SEC Rule 16b-3 Short-Swing Profit Liability Exemption

In Anderson v. Magellan Health, Inc., No. 2021-0202, — A.3d —-, 2023 WL 4364524 (Del. Ch. July 6, 2023) (McCormick, C.), the Delaware Court of Chancery addressed the circumstances under which the Court will award a shareholder plaintiff attorneys’ fees in disclosure-based deal litigation. In particular, Anderson analyzed the history of disclosure-based deal litigation in Delaware and the Court’s evolving standard for awarding fees where shareholder action has caused a company to issue additional pre-merger disclosures “mooting” pending deal litigation. Prior to the decision in Anderson, the state of the law was unsettled. The first line of cases would award fees as long as the shareholder plaintiff secured additional disclosures that were “helpful” such that they provided “some benefit” to shareholders. The second line of cases, however, adopted a stricter standard requiring that the supplemental disclosures be “plainly material.” In an effort to combat the so-called “deal tax” associated with disclosure-based merger litigation, Anderson comes out in favor of the stricter standard. Going forward, the Court will only award disclosure-based mootness fees when the complaining shareholder obtains additional disclosures that are “plainly material” to the shareholders. Companies, boards and advisors engaging in M&A transactions should pay attention to this decision as it will weigh on the proper strategy for approaching a shareholder challenge to an M&A transaction. Continue Reading Delaware Court of Chancery Clarifies Heightened Standard for Recovery of Attorneys’ Fees in Disclosure-Based Deal Litigation

In Lee v. Fisher, No. 21-15923, 2023 U.S. App. LEXIS 13521 (9th Cir. June 1, 2023), the United States Court of Appeals for the Ninth Circuit, sitting en banc, affirmed the dismissal of a shareholder derivative complaint alleging, among other things, violations of Section 14(a) of the Securities and Exchange Act of 1934 (the “Exchange Act”), 15 U.S.C. § 78n(a), and SEC Rule 14a-9, 17 C.F.R. § 240.14a-9 (collectively, the “Proxy Claims”), enforcing a forum-selection clause in the defendant company’s bylaws designating the Delaware Court of Chancery as the exclusive jurisdiction for adjudicating any derivative claims involving the company. By affirming the dismissal, the Ninth Circuit called into question whether the Proxy Claims were properly classified as derivative claims, noting that the Exchange Act’s antiwaiver provision was not triggered when the shareholder plaintiff could pursue the Proxy Claims directly in federal court. The Ninth Circuit’s decision creates a circuit split with the Seventh Circuit’s decision in Seafarers Pension Plan ex rel. Boeing Co. v. Bradway, 23 F.4th 714 (7th Cir. 2022), raising the specter that the United States Supreme Court eventually will weigh in on the issue.Continue Reading Ninth Circuit Enforces Delaware Forum Selection Clause to Affirm Dismissal of Derivative Claim for Alleged Violation of Section 14(a) of the Securities Exchange Act of 1934

In Slack Technologies, LLC v. Pirani, No. 22-200, 2023 U.S. LEXIS 2301 (U.S. June 1, 2023), the Supreme Court of the United States (Gorsuch, J.) held that Section 11 of the Securities Act of 1933 (the “Securities Act”), 15 U.S.C. § 77k, requires plaintiffs to show that they purchased securities registered under the registration statement they seek to challenge, a requirement the Supreme Court referred to as “tracing.” In Slack, the public offering occurred under circumstances that did not allow the plaintiff or other purchasers to trace any security to the challenged registration statement. As a result, the Court vacated the decision of a panel of the United States Court of Appeals for the Ninth Circuit that had relieved plaintiff of a tracing obligation. The Supreme Court’s unanimous opinion confirms that courts must strictly enforce Section 11’s tracing requirement even when doing so precludes all purchasers in an offering from accessing Section 11’s liability provisions.Continue Reading United States Supreme Court Holds That Section 11 Plaintiffs Must Purchase Securities Issued Under the Registration Statement They Seek to Challenge

In Pino v. Cardone Capital, LLC, 2022 U.S. App. LEXIS 35278 (9th Cir. Dec. 21, 2022), the United States Court of Appeals for the Ninth Circuit (Lynn, J.) joined with the Eleventh Circuit in holding that a person may qualify as a statutory “seller” within the meaning of Section 12(a)(2) of the Securities Act of 1933 (the “Act”), 15 U.S.C. § 77l(a)(2), by promoting the sale of a security in mass communications made on social media. Online videos and social media posts may trigger liability because Section 12(a)(2) does not require that a solicitation be directed or targeted to a particular investor. The Ninth Circuit’s holding highlights the risk that investment companies and their advisers face if they promote or otherwise discuss the merits of securities offerings online.Continue Reading Ninth Circuit Holds that Social Media Posts May Give Rise to “Seller” Liability Under Section 12(a)(2) of the Securities Act of 1933

In ZF Micro Solutions, Inc. v. TAT Capital Partners, Ltd., 2022 WL 4090879 (Cal. App. Aug. 8, 2022), the Fourth Appellate District of the California Court of Appeal decided, as a matter of first impression, that a non-derivative breach of fiduciary duty cause of action seeking compensatory damages was legal rather than equitable, and therefore required a jury trial as a matter of law. The Court arrived at its conclusion by evaluating the right and relief requested. In so doing, the Court concluded that because the claim at hand exhibited all the characteristics of a cause of action at law, it was legal, rather than equitable, and should have been tried to a jury.Continue Reading California Court of Appeal Holds that a Corporation’s Direct Cause of Action for Breach of Fiduciary Duty is Legal Rather than Equitable, Requiring a Trial by Jury
