MedAssets Inc. (NASD: MDAS) announced its stockholders approved an agreement to merge with Pamplona Capital Management LLP at its special meeting of stockholders held Jan. 14. MedAssets provides services to hospitals, and its business lines include a vendor management system that operates under the name MedAssets Workforce Solutions.

MedAssets announced the transaction in November, with plans calling for Pamplona to acquire MedAssets but after the sales is finalized, carve out a portion of MedAssets, including the VMS, and sell that portion to the VHA-UHC Alliance. VHA, a national healthcare network of nonprofit hospitals, and UHC, an alliance of academic medical centers, were combined into a single organization in April 2015.

The terms of the merger agreement call for Pamplona to acquire MedAssets for $31.35 per share in cash, a total enterprise value of approximately $2.7 billion.

The proposed acquisition is expected to close by the end of January and remains subject to certain other customary closing conditions.
