Yet LVMH is being penalized by shareholders for its disparate collection of businesses. Breaking up the behemoth could release significant value for investors. It might, incidentally, help solve the looming succession issue as founder and Chief Executive Officer Arnault comes closer to handing over the reins to the next generation.LVMH suffers from a conglomerate discount, because not only does it include its two biggest brands, Louis Vuitton and Dior, but it also has watches and jewelry, cosmetics, wines and spirits, duty-free retailing and hospitality. Shares in LVMH trade on about 16 times this year’s estimated earnings before interest and tax, less than half of Hermes International SCA’s 34 times.

Some discount to Hermes is warranted. The Birkin bag maker can, in effect, control demand for its iconic products. Meanwhile, LVMH’s valuation could also reflect concerns that its scale means there’s less room to grow and that Dior is decelerating after a remarkable run.Nevertheless, the markdown looks harsh. After all, Louis Vuitton is expected to generate €12.3 billion ($13.4 billion) of operating profit this year, an impressive 51.8% of sales, according to HSBC Holdings Plc estimates.Even on the simplest breakup valuation, the rationale for a split is compelling. For example, by putting Louis Vuitton and Dior on a multiple closer to that of Hermes than the rest of the fashion and leather-goods sector, these brands could be worth as much as the whole group, which currently has an enterprise value of about €360 billion.Luxury goods groups don’t do “buy one, get one free” deals. But in effect that’s what LVMH investors are getting. The other fashion and leather-goods houses within the LVMH stable, such as Loewe, Fendi and Celine, are being thrown in for nothing, as well as beauty retailer Sephora, jewelers Tiffany and Bulgari, and wines and spirits. That looks like a good reason to explore a separation.

Questions around LVMH’s structure need to be driven primarily by valuation. But dismantling the group might also help avoid potential pitfalls on succession. Arnault turns 75 in March, and all of his five children have senior roles within the business. Eventually, he will have to decide whether to pick one to be CEO or divide the responsibilities between them. Handing the reins over to an outsider looks unlikely, though he could appoint a non-family member as CEO until one of the next generation is ready to take over, emulating the arrangement at Prada SpA.Of course, no way of cleaving apart LVMH would be perfect. It could be split into four or five separate businesses, depending on whether Sephora continues to sit within a retail division or this unit is combined into an enlarged cosmetics and fragrance company, including brands such as Parfums Christian Dior, Guerlain and Fenty Beauty.There would also be some additional costs from each arm having to support its own central functions and head office. The individual businesses might have less clout than the behemoth when it comes to buying advertising, securing the best store locations, digital marketing and recruiting top talent. But synergies between luxury brands are relatively few. And an independent fashion and leather-goods business would still dwarf rivals.The biggest question is whether Arnault senior would really take an ax to the empire he has spent 40 years building. In fact, he has been taking steps to keep it together. In 2022, he orchestrated raising the age limit for his roles by five years to 80. He has also tightened the family’s grip, restructuring its holding company, Agache SE, into a limited partnership, with the patriarch as managing partner and the share capital held equally between the five children.But the debate will only intensify if the conglomerate discount remains — right now, luxury valuations are also depressed by slowing demand after the extraordinary boom of the past three years — and as we move closer to a decision on succession.Alternatively, a strategic shift could force it onto the agenda. A merger with Chanel might necessitate the separation of the enlarged fashion and leather-goods unit. Meanwhile, Diageo Plc owns 34% of LVMH’s wines and spirts division. The British company acquiring the remainder has long been seen as a possibility.Whether LVMH is more valuable together or split into its constituent parts is more of a PowerPoint idea for now. The company’s scale and the family’s control make an activist intervention unlikely. But for investors, it’s a conversation that needs to be had.
