What HPE Actually Agreed To

The Department of Justice sued in January 2025 to block HPE's 14 billion dollar acquisition of Juniper Networks, arguing the deal would concentrate the US enterprise wireless LAN market in too few hands. Days before the case was set for trial, the two sides reached a settlement: HPE would license the source code behind Juniper's Mist AI Ops platform to rival WLAN vendors and would divest its own smaller Instant On networking business to an approved buyer, a hybrid of a licensing remedy and a structural divestiture rather than blocking the merger outright.

That settlement is what Judge Pitts made final this week, closing a legal fight that outlasted the merger's own closing by more than a year. But the path from the original January 2025 complaint to this week's ruling ran through a hearing where the presiding judge himself was not sure the remedy matched the harm the government had originally alleged.

The Judge Who Doubted His Own Settlement

At a November 2025 hearing, Judge Pitts pressed both the government and HPE on why Instant On, a smaller SMB-focused wireless line, was the business being divested when the DOJ's original complaint had centered on Mist AI Ops and enterprise-grade WLAN management. Court reporting from that hearing, carried by PYMNTS and the Capitol Forum, quotes him telling the parties plainly that he did not recall reading about Instant On in the complaint at all. A December 31, 2025 order then laid out a discovery framework letting the intervening states probe how the settlement had actually been negotiated.

That skepticism did not evaporate by August 2026; it was resolved, not reversed. The Tunney Act, the 1974 law governing judicial review of DOJ antitrust settlements, does not ask a judge whether he personally finds a remedy elegant. It asks whether the states proved the remedy fails the public interest, a standard that leaves room for a judge to think a settlement is imperfect and still approve it.

A Process the Judge Called 'Machinations' -- and Approved Anyway

The states' intervention, described in filings publicized by the advocacy coalition Economic Liberties, did not attack the remedy's substance. It alleged HPE had retained lobbyists with close ties to the administration to help push the settlement through, and that two Justice Department officials were dismissed after objecting to how HPE pursued the deal internally. The allegation was serious enough that four US senators, including Elizabeth Warren and Cory Booker, publicly demanded a federal investigation into the settlement and the resignation of DOJ Chief of Staff Chad Mizelle.

Judge Pitts' own language, reported by both Bloomberg and MLex, split the two questions apart cleanly: he wrote that the states had performed an invaluable public service in bringing to light additional details about the machinations at the DOJ that led to the settlement, and then, in the very same ruling, found that they had not shown the amended proposed final judgment would fail the public interest. Under Tunney Act precedent, a court's job is to test whether the remedy is so inadequate that approving it would harm competition, not to referee how cleanly the government negotiated it.

The Decision Lesson: Winning Ugly Still Costs a Calendar Year

For any company, European or American, weighing how hard to negotiate a merger remedy against a skeptical antitrust enforcer, this ruling narrows the real legal exposure: a court applying the Tunney Act standard is testing the remedy's adequacy, not auditing the politics behind it. A rough, lobbyist-assisted process is not, by itself, the kind of defect that unwinds a settlement once a judge has to rule.

But the case also prices the other side of that same decision. HPE's settlement closed the underlying merger over a year earlier, yet the company spent 19 months, from the original January 2025 complaint to this week's final judgment, under discovery orders, contested hearings, and a public record that now permanently contains a federal judge's own word for how the deal was reached: machinations. A calmer negotiation, even one that produced the identical Mist AI Ops license and Instant On divestiture, would ordinarily have cleared the Tunney Act's standard public-comment window in under 90 days instead of 19 months. The lesson for a deal team is not that process is free to ignore; it is that the price of ignoring it is measured in legal spend and calendar time, not in the outcome itself.
