McKesson: Why The Best Is Yet To Come For This Drug Distributor

 | Jan 23, 2022 05:14AM ET

We have owned McKesson (NYSE:MCK) and its competitor Cardinal Health (NYSE:CAH) a few times over the last twenty years. This time around, we bought McKesson in November 2016 when the stock almost halved from a previous high.

Going into 2015, MCK’s business was overearning; it was benefiting from patent expirations of branded drugs. As a patent expires, a generic drug company that challenges the branded patent and drug distributors makes temporarily high profits for six months. In 2014–2015 there was a tsunami of branded drugs going generic.

In 2015 MCK was owned by growth investors that were looking for a continuation of double-digit earnings growth and price-to-earnings expansion. In 2016, earnings did not expand but contracted, and growth investors ran for the exits. The stock collapsed. This is when we made our first purchase (in this most recent ownership period). Our rationale was simple: We normalized (lowered) MCK’s margins to pre-branded expiration levels, and the stock looked attractive.

There was a lot to like—three drug distributors (McKesson is the largest) control over 90% of the drug distribution market. All three distributors are at scale and none has a competitive advantage against the others, thus none has a reason to start a price war.

Our thesis started to play out. Earnings stopped declining and were about to start growing, and then… Amazon (NASDAQ:AMZN) announced that it was entering the retail pharmacy space. MCK stock dropped, and we added to our position.
