The inside stories of messy marriage breakups have been an entertainment staple since even before Tolstoy observed that “every unhappy family is unhappy in its own way.” So let’s thank the supermarket giants Kroger and Albertsons, whose $24.6-billion merger has collapsed amid mutual recriminations, for their outstanding contribution to the genre.

The proximate cause of the breakup was the granting of a preliminary injunction against the deal by U.S. Judge Adrienne Nelson of Oregon. Nelson’s ruling, issued Tuesday, was a response to a motion by the Federal Trade Commission, the District of Columbia and eight states including California. (A state judge in Washington also ruled against the merger the same day.)

Although the two companies had fought the challenges to the merger seemingly hand in hand, their accord dissolved within 24 hours of Nelson’s ruling. Boise, Idaho-based Albertsons sued Kroger on Wednesday, citing the latter’s alleged “failure to exercise ‘best efforts’ and to take ‘any and all actions’ to secure regulatory approval” of the deal.

Kroger called Albertsons’ claims “baseless” and cited its would-be spouse’s “repeated intentional material breaches and interference throughout the merger process, which we will prove in court.”

Those of us who have followed the deal from its inception in 2022 can add this: “Good riddance.”

The collapse of the supermarket merger may stand as the final antitrust success of the Biden-era FTC, which has taken a hard line toward industry consolidations under Chair Lina Khan. Donald Trump is planning to nominate Andrew Ferguson, an FTC commissioner and conservative lawyer, as the agency’s chairman. Khan will be stepping down.

The two grocery chains maintained that they needed to merge in order to successfully compete with megastore chains such as Walmart and Costco, which have grown their grocery operations to the point that their sales approach those of Albertsons and Kroger or even exceed them.

The truth is, however, that the squalid nature of this transaction was always self-evident. As I wrote after the original announcement, the merger partners pitched it to the public as a boon to consumers. Merger partners always say this, but the consumer savings and service improvements generally prove elusive.

“We will take the learnings from each company to bring greater value and a better experience to more customers, more associates and more communities,” Kroger Chief Executive Rodney McMullen said then.

McMullen didn’t explicitly say that the deal would mean lower prices, but it would be a rare shopper who didn’t think that “greater value and a better experience” meant anything other than paying less at the checkout counter. Economists and antitrust experts predicted that the creation of a monopolistic supermarket giant would almost surely add inflationary pressure to food prices.

At the heart of the merger, as I further reported, was a $4-billion dividend to be paid to Albertsons stockholders. Six of the largest stockholders were corporate insiders, defined as holders of more than 5% of Albertsons shares each.

The biggest shareholder was the private equity firm Cerberus Capital Management, which owns more than 26% of the shares and has four nominees on the company’s board of directors. The other five are investment and real estate funds that hold a total of an additional three board seats.

The six investors control about 75% of Albertsons shares. In other words, they voted themselves a multibillion-dollar handout.

Albertsons had claimed that the dividend wasn’t connected to the merger but was “part of Albertsons’ long-term strategy for growth,” which was “determined well before Albertsons’ discussions with Kroger began.”

Yet the companies’ own merger announcement had stated explicitly that the $4-billion dividend was “part of the transaction.” They counted the dividend as part of the merger price, accounting for $6.85 per share of the $34.10 per share payable to Albertsons shareholders. The dividend was approved by the Albertsons board at the very same meeting at which it approved the merger deal itself.

It should go without saying that funneling $4 billion to insiders off the top wasn’t going to make it any easier to bring consumers lower prices at the checkout counter.

Then there was the issue of Albertsons’ corporate conduct. In October, Albertsons reached a $3.9-million settlement with the attorneys general of Los Angeles County and six other California counties as well as the FTC over accusations that the chain ripped off customers at hundreds of its Vons, Safeway and Albertsons stores in California. The company didn’t admit to liability in settling the case, but the terms of the final judgment suggest that the counties and the FTC had the goods — or at least had enough evidence that Albertsons thought it wise to make the case go away.

Albertsons says it has now implemented policies and employee training to ensure that its prices are accurate.

The principal issues raised by the FTC and the states concerned the prospects that the merger of America’s two biggest supermarket chains would allow them to dominate their markets as a monopoly or near-monopoly. That pointed to higher prices for customers and lower wages for workers, which are legitimate concerns for antitrust regulators.

Kroger, the largest chain, operates about 2,700 stores in 35 states and the District of Columbia, under brand names including Ralphs. Albertsons’ footprint encompasses about 2,300 stores under names such as Vons, Pavilions and Safeway. As Judge Nelson observed, the two chains have assiduously competed with each other for years, tracking each other’s prices in an effort to seize market share.

To meet the FTC’s objections, the merger partners proposed selling 579 stores to C&S Wholesale Grocers, a privately held supermarket supplier headquartered in New Hampshire that is a tiny fraction of the merger partners’ size — among other metrics, it has about 14,000 employees, compared with 430,000 employees at Kroger and 285,000 at Albertsons. The sale price was to be $2.9 billion.

Such divestitures are common features of merger deals that face regulatory challenge. But they don’t always meet their goal of preserving competition. A good example is the outcome of a divestiture scheme the FTC ordered in 2014, to mitigate the anticompetitive effects of Albertsons’ takeover of Safeway.

The FTC ordered the divestiture of 168 stores. More than 140 were acquired by Haggen Holdings, an 18-store chain in the Pacific Northwest. As it happened, Haggen was utterly ill-equipped to grow nearly tenfold overnight. Within months it was laying off workers, and before the year was out it had filed for bankruptcy.

Haggen put 100 of the stores back on the block, and 54 of them were reacquired by Albertsons as part of a deal to purchase Haggen outright. Even with the repurchases, the merger resulted in the elimination all competition in some communities.

That history gave Nelson pause when she assessed the new divestiture plan. C&S, she noted, didn’t have very happy experiences when it “dipped its toes into the grocery retail industry before.” The wholesaler bought 220 retail stores between 2001 and 2003, but had sold 190 of them by 2005. The company operates about 25 retail stores under the Piggly Wiggly and Grand Union brands; unlike Kroger and Albertsons, which incorporate pharmacies and gasoline stations into many of their locations, C&S operates only one pharmacy and no gas stations.

In short, Nelson observed, “there are serious concerns about C&S’ ability to run a large-scale retail grocery business that can successfully compete” with a merged Albertsons/Kroger. Among other issues, she wrote, C&S would have to re-brand about half the stores, a process that is “effectively the same as opening a new, unfamiliar grocery store in the eyes of consumers.” C&S didn’t respond to my request for a comment on Nelson’s take, though a spokeswoman told me by email that the firm is still committed to a “transformation strategy, which includes expansion into retail.”

As for the merger partners’ assertion that their deal was a defensive move against competitors such as Walmart and Costco, Nelson was unmoved. “The overarching goals of antitrust law are not met,” she wrote, “by permitting an otherwise unlawful merger in order to permit firms to compete with an industry giant.”

With the merger dead, the squabbling between the former partners is just beginning. Under their original deal, Albertsons is entitled to a $600-million breakup fee. But it says it will be seeking billions of dollars in costs, due in part to “the extended period of unnecessary limbo Albertsons endured as a result of Kroger’s actions.” Among other things, Albertsons’ asserted that Kroger dithered on divestiture deals that might have met the FTC’s objections.

In response, Kroger said it “went to extraordinary lengths to uphold the merger agreement throughout the entirety of the regulatory process and the facts will make that abundantly clear.”
