Investors in health-care stocks get rich as M&A booms

Deal premiums rise as takeover battles become common


Health-care M&A is on fire, with 23 of 36 takeout deals totaling more than $100 million each since the beginning of 2014.

Valeant Pharmaceuticals’ winning takeout bid for Salix Pharmaceuticals sheds light on other potential windfalls for investors as health-care companies feel the urge to merge.

Valeant VRX, -0.02% raised its cash offer for Salix SLXP, -0.16% to $173 from $158 a share, trumping a rival cash-and-stock bid of $172.50 a share from Endo International ENDP, +1.26%

ENDP, +1.26% Valeant’s original bid for Salix, which makes medications to treat digestive problems, was accepted by Salix on Feb. 20, and the original $158 offer represented a 27% premium over its closing share price 30 days earlier and a 54% premium over the closing price 90 days earlier.

It’s useful to look that far back when considering M&A premiums, because takeout rumors tend to drive stock prices up during the days leading up to deal announcements.

There have been 36 health-care M&A deals with values exceeding $100 million since the beginning of 2014, according to FactSet.
