Better Buy: GlaxoSmithKline plc vs. Eli Lilly

Choosing between investing in GlaxoSmithKline (NYSE: GSK) and Eli Lilly (NYSE: LLY) has been pretty much a no-brainer over the past few years. Lilly has trounced Glaxo in stock performance for the most part.

But looking only at the past isn't a smart move when trying to pick between GlaxoSmithKline and Lilly now. It's much more important to evaluate how each company is positioned for the future. Which drugmaker has the better prospects for the coming years? Here's how Glaxo and Lilly compare.

The case for GlaxoSmithKline

Before we get to GlaxoSmithKline's positives, let's look at the challenges facing the company. The biggest issue is that sales are falling for Glaxo's current top-selling product, Seretide/Advair, and that's not likely to change. Older drugs that have lost patent exclusivity, including Avodart and Seroxat/Paxil, are losing steam as well. Glaxo is also spending considerably more funding its dividend program than it's earning, spurring questions as to whether a dividend cut could be on the way.

On the other hand, the drugmaker has a solid lineup of newer products that are rising stars. Glaxo's newer respiratory drugs, including Anoro Ellipta, Relvar/Breo Ellipta, and Nucala, are enjoying strong sales growth. Momentum for these and other new drugs has been more than enough to offset sales declines for Seretide/Advair.

The drugmaker also has won a nice chunk of the market share in treating HIV. Sales for blockbuster HIV drugs Tivicay and Triumeq continue to grow rapidly. Several of Glaxo's vaccines are performing well, too, especially meningitis B vaccine Bexsero. Market research firm EvaluatePharma projects that sales for Bexsero will double by 2022 to around $1.17 billion.

Glaxo could soon add another blockbuster to its ranks. The FDA approved shingles vaccine Shingrix in October 2017. Shingrix demonstrated greater than 90% efficacy across all age groups in late-stage studies. The vaccine should pass the $1 billion sales level within the next few years.

As for the company's dividend, the yield currently stands at a hefty 5.31%. And while Glaxo's payout ratio is certainly higher than you'd like, the drugmaker is still generating enough free cash flow to more than cover its dividend payments. With the prospects for stronger growth over the next several years than the company has had in recent years, Glaxo's dividend should be on firmer ground in the not-too-distant future. Even if the company does cut its dividend, the likelihood is that the yield would still be attractive.
