UPDATE: A spokesperson for Mars Petcare US says its main office will remain in Nashville. "Upon closure of the transaction, we will seek to understand further the acquired brands, technology and markets. No changes are occurring at this time."
Mars Petcare, which runs its U.S. business from Williamson County, has signed a $2.9 billion agreement with Procter & Gamble to buy the majority of the latter's global pet foods division.
The two companies plan to complete their deal later this year. Mars Petcare employs more than 2,400 people in the United States, where it runs 15 manufacturing facilities, and a total of more than 35,000 people in 50 countries. Buying most of P&G pet foods business — the companies' agreement excludes many European Union countries — will add P&G's Iams, Eukanuba and Natura brands to a Mars lineup that includes Pedigree, Whiskas and Royal Canin.
"This acquisition is a perfect fit with our Mars Petcare vision," said Todd Lachman, Mars Petcare's global president. "The deal reinforces our leadership in pet nutrition and veterinary science, attracts world class talent and grows our world leading portfolio."
It's not yet clear how Mars Petcare's local operations will be affected by the planned transaction. The company is putting the finishing touches  on a Thompson's Station-based $88 million campus that includes both its headquarters — now in Cool Springs — and a research and development center. A Mars official did not immediately return a message Wednesday.
Sales figures for P&G's petcare business aren't readily available. But it appears Mars executives will have their hands full once they take over: In its recent quarterly report with the Securities and Exchange Commission, P&G said "Pet Care volume decreased high single digits primarily due to the continuing impact of product recalls in the previous fiscal year for Natura. Global market share of the pet care category was down more than half a point."
