Publicly disclosed merger and acquisition activity for private tech companies reached $46.8 billion last year across 2,277 transactions, according to a new report from CB Insights.
The $46.8 billion figure comes from just 331 deals where the valuations were disclosed, as only 15% of transactions made the financial terms public.
Google and Facebook were the most active acquirers with 12 private acquisitions each. Five of Facebook’s deals were talent acquisitions, or “acqui-hires”.
Interestingly, the bulk of acquired companies had not raised investment. 76% of private tech companies that were bought up last year had bootstrapped instead of turning to VCs.
As expected, California saw the most private tech M&A deals last year, more than the next five states combined. North Dakota was the only US state that didn’t host a private tech acquisition in 2012. Internationally, the UK was the top acquirer, followed by Canada. India emerged as an up-and-comer at the third top international market.
Web and mobile commerce were the most popular types of companies to acquire, comprising 173 of overall deals.
An earlier report on the venture capital market found that $28.3 billion in investments had been made last year, down from $30.6 billion in 2011.
