Acquisition activity during the first half of the year (Q1 2009, Q2 2009) was excruciatingly slow.  Economic turmoil forced many companies to keep a close watch on their wallets. As a result Q1 and Q2 combined saw a mere 45 total acquisitions for a measly $7.3 billion.

Q3 2009, however, has shown a complete turnaround. With a total of 47 acquisitions amounting to approximately $18.2 billion (only 20 were disclosed), activity for this past quarter has already surpassed that of the entire first half of the year. In fact, Q3 2009 shows more than double the number of acquisitions than any of the previous four quarters, while the combined total amount still doesn’t exceed that of Q3 2009 alone. Here’s the breakdown:

  • Quarter 3 2008: 18 acquisitions ($5.0 billion)
  • Quarter 4 2008: 15 acquisitions ($3.0 billion)
  • Quarter 1 2009: 21 acquisitions ($1.5 billion)
  • Quarter 2 2009: 24 acquisitions ($5.8 billion)
  • Quarter 3 2009: 47 acquisitions ($18.2 billion)

We’d like to say thanks to all of the great blogs out there (TechCrunch, GigaOM, Mashable, VentureBeat and more) whose frequent tracking of acquisitions makes this list possible.

If you know of any acquisitions that we’ve missed, please leave a comment on this post and we’ll update it.
