Regulatory compliance imposes substantial costs on companies considering acquisitions or mergers. At the federal level, transactions that meet certain thresholds are prohibited from closing until they have been evaluated by the antitrust regulators to determine whether competition is threatened. The process can be lengthy and expensive, but in instances where the parties are ultimately cleared or have agreed to conditions that address agency concerns, they can move forward with the transaction as far as the federal antitrust regulators are concerned.
Increasingly, however, the path to closing is delayed by state regulators that wait until after federal review is complete before initiating separate investigations at the state level. For example, this year a group of eight state attorneys general brought a lawsuit attempting to block the purchase of Tegna by Nexstar Media Group during the same week that the Department of Justice and Federal Communications Commission approved the transaction. It has also been reported that several states are considering launching a challenge to Paramount Global’s planned acquisition of Warner Bros. Discovery despite the Justice Department’s decision to clear the deal following an extensive investigation.
The timing of these state challenges is problematic. Even if the lawsuits are unsuccessful, they will have added months of delay, if not years, to the parties’ ability to integrate their firms and proceed with their business plans. Moreover, until the litigation is completed, the parties must incur still more legal expenses, all the while facing uncertainty about the outcome, which can mean forgoing strategic opportunities that otherwise would have been seized by the combined firm.
In addition to their own lawsuits under state law, some state attorneys general have also taken to challenging federally negotiated agreements during Tunney Act proceedings. As a former Justice Department Attorney and FTC Policy Planning Director explains, under the Tunney Act, courts review DOJ antitrust settlements to assure the public that “the Justice Department followed proper procedures, disclosed sufficient information, and explained the rationale behind its decision.” Significantly, “[t]he courts have been unambiguous that the law prohibits them from substituting their judgment for the judgment of the Justice Department.”
In an ongoing Tunney Act matter, the attorneys general of nineteen states and the District of Columbia are challenging the adequacy of DOJ’s settlement agreement with Hewlett Packard Enterprise respecting its proposed acquisition of Juniper Networks. In their letter to the court, the state attorneys general allege that the “terms of the Settlement are themselves bizarre and raise suspicion,” and that the settlement may be a consequence of “lobbying pressure and secret side arrangements [that] substituted for antitrust legal analysis.” If so, “the DOJ breached the public trust.”
In principle, these allegations, if true, may be proper Tunney Act concerns. The state attorneys general, however, do not stop there. They also challenge the substance of the settlement, which they claim fails to “address the harms alleged by the DOJ.” Here they claim that the DOJ abandoned its own factual record in arriving at the settlement. In making this claim, the state attorneys general ask the court to substitute their analysis of the record for that of the DOJ’s, effectively asking the court to re-examine the substantive issues in the case.
In point of fact, the settlement is hardly a give-away to the parties. Among other things, the settlement requires that the parties undertake certain divestitures and enter into mandatory licensing agreements. After months of investigation and negotiation, the DOJ concluded that these terms will be effective in disposing of the acquisition’s potential harm to competition. One need not agree with this conclusion, but a Tunney Act proceeding is not the place to ask a court to reach an alternative conclusion.
In sum, when state objections to a transaction under state law do not emerge until after (or only shortly before) the federal antitrust review process is completed or when states challenge the adequacy of federal settlements, the result is a regulatory review system of sequential proceedings rather than a coordinated regulatory review process among federal and state actors. This situation begs for reform. On both fairness grounds and cost mitigation grounds, parties subject to merger review should be able to identify a reasonable time frame for ending the process.
In this regard, federal and state enforcers should work to better coordinate reviews of specific transactions such that their respective reviews reach conclusions reasonably close in time, if not simultaneous. Some options might include sharing information and data, identifying common competitive concerns, and agreeing on parameters that when present result in state deference to federal clearances or settlements. State attorneys general could also commit to inform the parties of their additional competitive concerns during the federal review process whenever possible. None of these reforms would prevent states from bringing suits under state laws. They would, however, help to establish a clearer and more predictable enforcement framework.
The absence of a predictable time frame for governmental merger review neither serves the parties nor enhances in any meaningful way competition enforcement. To the contrary, when federal and state reviews take place in sequential time periods, business uncertainty, legal expenses, and the costs of complying with information and data demands are significantly elevated. These consequences occur even if state attorneys general do not ultimately bring charges or prevail in court. Better federal and state coordination in the timing of their respective reviews is needed, and the federal agencies and state authorities should work toward that end.
