The Top 10 Device and Diagnostics Deals of 2012

The corridors of power are a tad quieter when Johnson & Johnson ($JNJ) isn't around to wield its outsize checkbook. Last year, J&J topped our deals list with a $21.3 billion handshake to soak in Synthes, so 2012 was relatively tame in comparison, as the titans of devices and diagnostics largely held back on banner acquisitions or opted instead to dink and dunk as needed--the Boston Scientific ($BSX) method.

But what 2012 has so far lacked in big dollar figures it has made up for in number of transactions. According to Irving Levin Associates, we're on pace to hit about 180 deals for the year, matching the average of the past three years. Furthermore, analysts have said CEO shakeups and political uncertainty put a strain on M&A in 2012, and we're likely to see a jump in acquisitions come next year, once U.S. healthcare reform is all sussed out and the device tax has softened the margins of would-be targets.

However, a closer look at the numbers reveals what could be an alarming trend in the device world: All of the billion-plus exits went to diagnostics outfits. It's easy--and accurate--to point to the hand-over-fist growth we've seen in the diagnostics industry of late, as most of the big-time Dx firms have met or exceeded their 2011 revenues in just 9 months of 2012. As the demand for molecular and companion diagnostics continues to climb, more consolidation is likely.

On the device side, the two most noteworthy deals focused on the future. Medtronic's ($MDT) $816 million acquisition of China Kanghui Holdings is in lockstep with the company's vow to get more and more of its annual revenue from emerging markets. Boston Sci's $425 million bet on Vessix Vascular was an entry fee to join the race to cash in on the soon-to-explode renal denervation market. Otherwise, slumping sales for device mainstays like implantable defibrillators and stents kept bold-print deals to a minimum.

That could change in a hurry, however. Baxter ($BAX) is rumored to be on the verge of a $4 billion buy of Gambro AB, a maker of dialysis machines. And, if analysts and unnamed sources are to be believed, we could be in for large-scale bids on the likes of Edwards Lifesciences ($EW), Illumina ($ILMN) and Volcano ($VOLC). -- Damian Garde (Twitter | email)
