NEW YORK (TheStreet) -- Thermo Fisher Scientific (TMO) - Get Report stock closed up by 0.57% to $141.59 on Thursday, after the company completed its $1.3 billion acquisition of Affymetrix (AFFX), which was threatened after OriginTechnologies made a competing takeover bid earlier this year. 

The scientific equipment provider's acquisition was completed after Affymetrix shareholders approved the merger agreement at a meeting on Thursday, Thermo Scientific said in a statement. Affymetrix is a provider of life science products and molecular diagnostic products.

Thermo Fisher's management was patient and didn't "take the bait to raise their own bid," TheStreet's Jim Cramer, Portfolio Manager of Action Alerts PLUS,wrote in an article today

"TMO is very shrewd when making capital allocation decisions," Cramer and Research Director Jack Mohr said. "CEO Marc Casper and his team recognized that while AFFX certainly would be a positive addition to the company, the deal wasn't worth overextending TMO's funds with a higher bid as the money would have been better used in other ways to benefit shareholders."

"While AFFX is not material to the long-term TMO thesis, it should prove to be a nice asset and we are happy to move past the noise," Cramer and Mohr added. 

(Thermo Fisher is held in Jim Cramer's charitable trust Action Alerts PLUS. See all of his holding with a free trial.)
