Arxada AG on Thursday, Dec. 23, announced the completed acquisition of U.S. antimicrobial products specialist Enviro Tech Chemical Services Inc., in a deal the Swiss specialty chemicals producer said will give it direct access to the $6 billion U.S. food and beverage hygiene market.

No financial terms were disclosed. However, The Deal’s Tom Terrarosa wrote in November that, based on a likely multiple of between 15 and 20 times Ebitda of $35 milion to $40 million, a buyout could value Enviro Tech at anywhere between $525 million and $800 million.

Four bidders — Arxada, Danaher Corp. (DHR), Arsenal Capital Partners LP and Arcline Investment Management LP — made it to the final stages of a Capstone Partners LLC-run process for the family-owned disinfectants maker, sources familiar with the process previously told The Deal.

The acquisition represents the second strategic deal by Arxada, formerly known as Lonza Specialty Ingredients, in its first six months as an independent company.

Arxada was carved out of Basel, Switzerland-based chemicals company Lonza Group AG by private equity firms Bain Capital LLC and Cinven Partners LLP, in a deal that closed in July. On Nov. 3, Arxada announced the purchase of U.S. coatings and additives specialist Troy Corp. for 4.2 billion Swiss francs ($4.6 billion).

Arxada said the acquisition of Modesto, Calif.-based Enviro Tech will create a new, complementary business line in its existing microbial control solutions business and will be led by Enviro Tech president Brent Bankosky. Mike Harvey, Enviro Tech founder and CEO, will join Arxada as senior fellow in its technology and regulatory unit.

Kirkland & Ellis LLP and Baker & McKenzie LLP are legal advisers to Arxada, Bain and Cinven, while Deutsche Bank is providing financial advice.

A Capstone Partners LLC team of Samrat Karnik and Doug Usifer acted as strategic adviser to family-owned Enviro Tech.

Weintraub Tobin Chediak Coleman Grodin Law Corp. is legal adviser to Enviro Tech.
