States Expand Premerger Filings Family by Adopting “Baby-HSR” Laws to Review More Transactions
In a growing trend, states are requiring more premerger filings by enacting “baby-HSR” laws modeled after the federal Hart-Scott-Rodino (HSR) Act. These state-level statutes require parties to certain mergers and acquisitions to make an informational filing and, in certain cases, observe a waiting period before a transaction can be completed. While most state-specific laws have been limited to transactions involving the health care sector, Washington state is now the first state to expand their health care provider-focused statute to also capture transactions across all industries where one of the parties has its principal place of business located in the state or has significant annual sales in the state. The law goes into effect on July 27, 2025.1 Other states may follow suit to require filings in connection with transactions across all industries based on a similar “nexus” with the state.

Wilson Sonsini Helps Secure EC Clearance of Run:ai’s Acquisition by NVIDIA
On December 20, 2024, the European Commission (EC) unconditionally approved the proposed acquisition of Run:ai Labs by NVIDIA Corporation under the EU Merger Regulation. The EC concluded that the transaction would raise no competition concerns in the European Economic Area (EEA). Wilson Sonsini Goodrich & Rosati represented Run:ai in securing the unconditional clearance.
U.S.-based NVIDIA designs and supplies graphic processing units (GPUs), a type of semiconductor for data center applications. Israel-based Run:ai supplies GPU orchestration software allowing corporate customers to schedule, manage, and optimize their AI compute infrastructure. NVIDIA’s proposed acquisition of Run:ai was notified to the EC on November 15 following a referral request from the Italian national competition authority. The EC investigated the impact of the transaction on the markets for the supply of discrete GPUs for use in data centers and GPU orchestration software. It assessed whether, post-transaction, NVIDIA would be able to hamper the compatibility between its GPUs and the GPU orchestration software of Run:ai’s competitors, and the compatibility between Run:ai’s software and the GPUs of NVIDIA’s competitors. The EC concluded that the proposed acquisition would not raise competition concerns in any of the markets examined in the EEA or Italy, and therefore cleared the transaction unconditionally.
The Wilson Sonsini antitrust team that secured the clearance for Run:ai included Jamillia Ferris, Deirdre Carroll, Michelle Hale, Matthew McDonald, Ben Labow, Kimberley Biagioli, Rachel Burke, Lindsey Edwards, Rose Reinacher, John Sack, Laurine Daïnesi Signoret, Dillon Ostlund, Jacob Lozano, Michelle Zang, Sabin Chung, and Rohena Rajbhandari.

Shot, Chaser: FTC Sues Alcohol Supplier Under Controversial Pricing Law, Dissenting Commissioner Offers Detailed Defense
On December 12, 2024, the Federal Trade Commission (FTC) sued Southern Glazer’s Wine and Spirits, LLC (Southern) in the Central District of California for alleged price discrimination, initiating the first federal government enforcement action under the Robinson-Patman Act (RPA) in nearly 25 years.1 Much ink was spilled across statements issued by FTC Commissioners Alvaro Bedoya, Andrew Ferguson, and Melissa Holyoak about the history of the enactment and enforcement of the RPA and various statutory interpretation arguments. That commentary is certainly interesting reading to better understand dueling views on the origin and purpose of the RPA, but the key takeaways for suppliers and retailers assessing legal risk under the RPA are: the RPA remains good law, the FTC has delivered on its promise to revive enforcement, and the incoming Chair for the Trump Administration—Commissioner Ferguson—is open to future RPA enforcement, particularly when the favored buyer has market power.

Spoiled Goods: FTC Denied Adverse Inference Request for Missing Texts in Kroger-Albertsons Merger Trial
On August 16, 2024, the Federal Trade Commission (FTC) filed a motion in limine in its challenge to Kroger’s $24.6 billion acquisition of Albertsons alleging that Albertsons executives intentionally deleted text communications about the merger.1 The FTC’s motion asked the court to infer that the executives’ allegedly deleted communications would have been harmful to the companies’ defense of the merger. In addition to seeking an adverse inference about the content of the responsive text messages, the FTC requested that the court “treat with skepticism” any trial testimony from certain Albertsons executives, including CEO Vivek Sankaran, about the effects of the proposed merger or the parties’ planned divestitures.2

FTC Pioneers Novel Remedies in the Exxon/Pioneer Merger
On May 2, 2024, the Federal Trade Commission (FTC) announced a consent order in the matter of Exxon Mobil Corporation’s (Exxon) acquisition of Pioneer Natural Resources (Pioneer). The consent order is unusual in that the sole remedy obtained by the FTC is a prohibition on certain appointments to Exxon’s Board of Directors (Board) post-merger.1 The FTC alleges that the bans instituted by the consent decree “limit[] the likelihood of coordination in crude oil markets.”2 FTC Commissioners Melissa Holyoak and Andrew Ferguson voted against the consent order and authored a joint dissenting statement expressing concern that the FTC is “leveraging its merger enforcement authority to extract a consent from Exxon” without articulating how the transaction violates Section 7 of the Clayton Act.3 FTC Chair Lina Khan and Commissioners Alvaro Bedoya and Rebecca Slaughter voted in favor of the consent order and each issued statements defending the FTC’s decision to impose a remedy.
