Healthcare is the fourth-best performing sector for global M&A during 2013, according to a Fortune report citing preliminary Thomson Reuters data.

Many other sectors are not faring as well, as global M&A activity appears to have hit a three-year low in Q2 2013. The Thomson Reuters data also indicates that Q2 2013 was the slowest quarter for global PE since Q3 2010.

M&A activity in the U.S. declined in Q2 2013, down 16 percent, but for the year it remains up 34 percent.

Here are just a few of the larger healthcare M&A deals in 2013:

  • Valeant Pharmaceuticals to acquire Bausch + Lomb Holdings for $8.7 billion
  • Actavis to acquire Warner Chilcott for approximately $8.5 billion
  • McKesson acquires PSS World Medical for approximately $2.1 billion
  • Catholic Health Initiatives acquires St. Luke’s Episcopal Health System for approximately $2.0 billion
  • Tenet Healthcare to acquire Vanguard Health Systems for $1.73 billion
  • Roper Industries acquires Managed Health Care Associates for approximately $1.0 billion

The top three performing global M&A sectors for 2013 are energy and power, real estate and financials.
