Delaware Court of Chancery Issues First Decision Addressing Public Benefit Corporations
On July 29, 2026, Vice Chancellor Nathan Cook of the Delaware Court of Chancery issued a decision addressing, for the first time, the fiduciary duties of directors of a public benefit corporation (PBC)—including in a sale of control.1 Under the PBC form, the purpose of corporate decision-making is not merely to advance stockholder value—as is the ultimate purpose of decision-making for a traditional Delaware corporation—but instead to balance three sets of interests: a specific public benefit purpose chosen by the PBC, the best interests of those materially affected by the corporation’s conduct, and stockholders’ pecuniary interests.2 Delaware law first authorized the PBC form in 2013, and since that time, the form has grown in prominence, with many significant public and private companies operating as PBCs. Until this decision, however, there had not yet been direct case law guidance addressing PBCs. The decision, accordingly, is noteworthy for PBCs and companies considering adopting the PBC form.

DOJ Revives Targeted Second Requests for Merger Review
On July 23, 2026, the Department of Justice (DOJ) Antitrust Division announced a return to “targeted” Second Request investigations and published a revised model timing agreement. The agreement offers an optional “Expedited Consideration” process potentially allowing investigations to be resolved without a full Second Request production. Under the expedited procedures, parties produce a limited set of documents, data, and information relevant to particular issues and concerns raised by the Antitrust Division. If the targeted production is sufficient to resolve the DOJ’s concerns, the investigation may be terminated without full Second Request compliance. In addition, the targeted production may provide a context for potential settlement negotiations. If concerns remain, the DOJ may require further productions, either of the full Second Request specifications or on modified terms.

Back-to-Back Executive Orders Shape the U.S. Quantum Agenda: What Founders and Investors Need to Know
On June 22, 2026, the administration issued two Executive Orders: Executive Order 14413, Ushering in the Next Frontier of Quantum Innovation (Quantum Innovation Executive Order) and Executive Order 14412, Securing the Nation Against Advanced Cryptographic Attacks (Post-Quantum Cryptography Executive Order). Together, the Executive Orders reinforce the federal government’s long-term commitment to quantum information science and technology (QIST) while continuing to frame quantum as both an economic and national security priority. Although they impose relatively few immediate legal obligations on most companies, the Executive Orders provide important signals about where federal investment, procurement, and strategic partnerships are likely to emerge over the coming years.
