The world’s biggest luxury goods company is buying US-based jeweller Tiffany & Co for more than $16bn (£12.5bn).
The deal gives LVMH’s billionaire owner Bernard Arnault a bigger slice of one of the fastest growing luxury sectors.
He said Tiffany had an “unparalleled heritage” and fitted with its other brands, Louis Vuitton and Bulgari.
Tiffany has suffered falling jewellery sales, hit by lower spending by tourists and a strong US dollar.
Tiffany is something of a New York institution and its flagship store is next to Trump Tower on 5th Avenue. The company hit global fame after being featured in the 1961 Audrey Hepburn film Breakfast at Tiffany’s.
Founded in 1837, it employs more than 14,000 people and operates about 300 stores.
Mr Arnault has coveted the business since buying the Bulgari brand in 2011 for $5.2bn. The Tiffany acquisition is LVMH’s biggest deal.
“We have an immense respect and admiration for Tiffany and intend to develop this jewel with the same dedication and commitment that we have applied to each and every one of our Maisons [brand houses],” he said.
LVMH has 75 brands, 156,000 employees and a network of more than 4,590 stores. Other brands include Kenzo, Tag Heuer, Dom Pérignon, Moet & Chandon, and Christian Dior.
“We will be proud to have Tiffany sit alongside our iconic brands and look forward to ensuring that Tiffany continues to thrive for centuries to come,” Mr Arnault said.
Known for its signature robin’s-egg blue packaging, Tiffany rebuffed LVMH’s initial advance made just five weeks ago, arguing it significantly undervalued the company.
The deal values each Tiffany share at $135 in cash and is higher than the initial offer of $120 a share – which valued the business at $14.5bn.
Roger Farah, chairman of Tiffany, said the board had concluded this deal “provides an exciting path forward with a group that appreciates and will invest in Tiffany’s unique assets and strong human capital”.
The brand is associated with diamond rings but it has lost its appeal in recent years, according to Fiona Cincotta, market analyst at City Index,
She told the BBC’s Today programme that there had been a “changing of the times”.
“It’s not quite keeping up with millennials so it just needs a re-boost and a re-brand,” she said.
LVMH has experience of revitalising businesses. She mentioned jeweller Bulgari, which when LVMH took it over in 2011 had operating margins of 8%. These have now widened 25% on double the sales.
“This something that LVMH appears to do very well… this is a real turnaround story,” she said.
Jewellery was one of the strongest performing areas of the luxury industry in 2018, according to consultancy Bain & Co, which forecast that comparable sales in the $20bn global market were expected to rise by 7% this year.
This has encouraged firms to expand in the sector. Luxury goods firm Kering has launched high-end jewellery lines for its fashion brand Gucci, while Switzerland’s Richemont – a sector leader with labels such as Cartier – recently bought Italy’s Buccellati.
As part of its push for a bigger share of the US market, LVMH has opened a factory in south Texas. The plant was officially inaugurated last month in a ceremony attended by Mr Arnault and US President Donald Trump and his daughter Ivanka.
