Who is off the ST50 list this year?

Deals

Three companies from last year's list didn't make it this year because acquisitions closed just as the new year started. Financial results were not disclosed for the latest quarters.

St. Jude Medical, which ranked 16th last year, was the largest to be acquired. Abbott Laboratories closed on the $25 billion deal on Jan. 4.

Datalink, 36th last year, was acquired by Insight Enterprises Inc. on Jan. 6 for $11.25 per share, or about $258 million.

Vascular Solutions was 64th last year. One of the faster-growing companies on last year's list, revenue grew 16.7 percent in 2015. Vascular Solutions would have ranked higher this year but was acquired by Teleflex Inc. on Feb. 17 for $1 billion.

G&K Services and Cintas Group announced their $2.2 billion deal in August, but since the deal did not close until March 21, thus allowing for updated financial information, G&K was listed for one more year. The company will exit at No. 32.

More confirmation to shrink our list came when additional Minnesota-based public companies announced deals this year.

OneBeacon Insurance Group (30th this year) announced May 3 that it would be acquired by Canada's Intact Financial Corp. The $1.7 billion deal should close in the fourth quarter.

Arctic Cat, the Plymouth-based maker of snowmobiles and all-terrain vehicles ranked 40th, announced on Jan. 25 a $247 million deal with Textron Inc. and closed on it March 6.

Silver Bay Realty Trust (51st) will not make future lists. It announced a $1.4 billion offer by Toronto-based Tricon Capital Group on Feb. 27 and closed the deal May 9. Also outside the top 50 and soon ineligible, Mocon Inc. (64th) announced it would be acquired by Ametek Inc. for $182 million.
