The big acquisition news coming out of Q1 2009 is really no news—activity remains slow. M&A activity began cooling down during Q3 2008 and has remained fairly stagnant since then. Last year at this time we saw 22 disclosed acquisitions with a total dollar value of $4.75 billion. Q1 2009, however, saw only six disclosed acquisitions totaling $1.5 billion.

Though only six of this quarter’s acquisitions were disclosed, there were actually 21 total companies bought and sold, 15 of which were undisclosed. When acquisitions are undisclosed, this typically means they are much smaller and immaterial in terms of dollar value.

There were six more acquisitions this quarter compared to Q4 2008; however, two of this quarter’s six disclosed acquisitions (Cisco’s acquisition of PureDigital and Autonomy’s acquisition of Interwoven) made up $1.37 billion of the $1.5 billion total. So although the actual number of acquisitions rose, the actual dollar values are likely much lower than past quarters.

We’d like to say thanks to all of the great blogs out there (TechCrunch, GigaOM, Mashable, VentureBeat, ReadWriteWeb 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.
