Health care is perhaps the most talked about industry today. Between the implementation of the Affordable Care Act (ACA) and the push for lower health care costs with better outcomes, companies in the industry are constantly changing. Innovation and volatility often translate into plentiful M&A opportunities, as organizations remake themselves or grow to meet shifting demands. However, it's important to note that while opportunities were plentiful in 2013, dealmakers were cautious. This was widely blamed on dealmakers taking a wait-and-see approach to the rollout of ACA. However, with the ACA now taking full effect, the hesitancy toward investing in the sector is expected to dissipate in 2014.
