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.
