Better Biotech Buy: Biogen Idec Inc. (BIIB) vs. Celgene Corporation (CELG)

Buying big pharma stocks isn’t the only way you can invest in today’s best-selling drugs without taking a gamble on a small, risky biotech. Some of yesterday’s fledgling biotech companies have become today’s powerhouses, boasting substantial pipelines and strong sales. Biogen Idec Inc. (NASDAQ:BIIB) and Celgene Corporation (NASDAQ:CELG) have emerged as two of the top companies in the “big biotech” industry, and both stocks have rewarded shareholders handsomely recently: Celgene’s stock has rocketed up 50% over the past year, while Biogen’s has impressed by rising 46%.

There’s no doubting these stocks’ place at the top of the biotech arena, but the question is: Which one is the better buy?

Looking at the basics
Biogen Idec Inc. (NASDAQ:BIIB)Biogen Idec Inc. (NASDAQ:BIIB) hasn’t had much trouble on the financial side of things lately. The company’s driven revenue higher consistently in the last couple years, posting 9.2% growth in 2012 after 2011’s revenue rose 7% year-over-year. Those are appealing numbers for growth investors, and with Biogen following up by growing its diluted earnings per share in both 2011 and 2012, this company’s having no trouble showing shareholders the money.

Not that Celgene Corporation (NASDAQ:CELG)’s having much trouble, either. It actually outperformed  Biogen on a purely financial basis over the last couple years, raking in revenue growth of 13.7% in 2012 after a phenomenal 2011 brought in year-over-year growth of nearly 34%. Like Biogen, Celgene’s also done well in growing EPS over the past two years.

With success comes a cost, however: You’ll be paying a hefty premium for either of these hot stocks. Biogen trades at a price-to-earnings ratio of 30.7, with Celgene at an even stiffer 34.6 after its recent run-up. That’s in line with some of the other top biotech and pharmaceutical stocks, but these two companies will have to keep producing top-notch growth in order to keep up with investors’ optimism.

Can they do that? Fortunately, Celgene and Biogen both sport a number of drugs on the market and solid pipelines.

Celgene’s Revlimid advantage
Five drugs currently make up most of Celgene’s sales, but multiple myeloma drug Revlimid is the engine that makes the company go. The company’s top seller sold more than $3.7 billion last year, growing an outstanding 17.4% year-over-year. Revlimid’s patent won’t expire until 2027 in the U.S. and 2024 in Europe, offering Celgene Corporation (NASDAQ:CELG) plenty of time to take advantage of the exploding multiple myeloma market.

Research and advisory firm Decision Resources expects the market to climb to $7.2 billion by 2021 from $4.4 billion in 2011, and forecasts Revlimid to capture 64% of that market. That forecasts sales of more than $4.6 billion for Celgene’s leading drug, and while it still faces competition from Johnson & Johnson (NYSE:JNJ)‘s Velcade — which has become one of J&J’s fastest growing blockbusters — Decision Resources predicts Velcade to remain in second place in this lucrative and growing market.

Celgene’s other drugs pale in comparison to Revlimid, unfortunately. The company’s nearly $3 billion acquisition of Abraxis BioScience in 2010 brought cancer drug Abraxane into the fold, but it currently only brings in about 11% of what Revlimid does. Its 10.6% growth in 2012 underperformed Celgene’s total revenue growth, and it’s looking like the Abraxis purchase might not have been the best decision. Abraxane still has a long time to prove itself — the drug doesn’t lose patent exclusivity until 2026 in the U.S. and 2022 in Europe — but so far, its effect has been limited.

MDS drug Vidaza ranks as Celgene’s second-best seller and has posted strong growth, but with its U.S. patent protection having expired in 2011, any generic competitor that successfully rises will strain sales. Don’t put your faith going forward in this drug.

This all makes Celgene excessively dependent on Revlimid’s success, but the company’s pipeline isn’t bare. Its new multiple myeloma drug Pomalyst won FDA approval in February and is expected to hit peak sales of $1 billion or more. Celgene’s oral psoriasis candidate Apremalist hit a road bump recently in phase 3 trials, reporting data that failed to match up with mid-stage efficiency results. Apremalist is likely to land FDA approval, but Celgene’s rosy peak sales estimates of $1.1 billion or more look like they’ll be tough to match — particularly as Apremalist will have to battle AbbVie Inc (NYSE:ABBV)‘s leading drug, Humira, the blockbuster behemoth that made more than $9.2 billion last year. Gulp.

Biogen’s growing portfolio
Celgene has its perks, but Biogen has plenty to keep investors happy as well.

Biogen Idec Inc. (NASDAQ:BIIB)’s success begins and ends with the multiple scleroris market, and its tried-and-true drug Avonex leads the way. Avonex pulled in more than $2.9 billion in 2012, posting year-over-year growth of 8.4%. Fellow MS drug Tysabri also pulls its weight at Biogen, racking up more than $1.1 billion in revenue last year with smaller growth. Both drugs remain key players in an MS market that’s expected to grow by more than $4 billion between 2011 and 2016.

To keep up with that trend, Biogen bought out Tysabri co-marketer Elan Corporation, plc (ADR) (NYSE:ELN)‘s stake in the drug to capitalize fully on its growth. Biogen paid Elan a hefty $3.2 billion for the stake, but Tysabri’s expected to remain a critical cog in MS treatment that analysts expect could hit sales of $1.9 billion by 2018. Elan will still receive a percentage of global sales of Tysabri in the future, but the move gives Biogen full control over its blockbuster drug. Combined with the company’s victory in gaining extended patent protection for Avonex until 2026, Biogen’s looking good in this growing market for the future.

But is the company too focused on multiple sclerosis? Rituxan — which Biogen co-markets with Roche and is cleared to treat non-Hodgkin’s lymphoma, rheumatoid arthritis, and more — also brought in more than $1 billion in 2012, providing necessary diversity.

However, it’s Biogen’s future that truly looks promising. Oral MS drug BG-12 still is waiting for an FDA approval, but expectations are through the roof. Peak sales estimates average around $3 billion, a mark that would eclipse any of Biogen’s current drugs. With late-stage drugs in the pipeline for lymphomas, hemophilia, and more, Biogen’s future looks safe — especially with BG-12 in hand.

Which stock has the edge?
So, which one of these top biotech stars should you pick?

Celgene Corporation (NASDAQ:CELG) has plenty going for investors: With Revlimid’s dominant position in the growing multiple myeloma market and years of patent protection ahead, shareholders don’t have to worry about sales dropping off any time soon. The company should continue to see strong growth from Revlimid, even as Vidaza continues with the shadow of potential generic competition looming over it and Abraxane continues to chug along underwhelmingly. However, with Apremalist’s disappointing recent results, only Pomalyst looks to provide serious growth after Revlimid.

Biogen Idec Inc. (NASDAQ:BIIB), on the other hand, offers diversity and growth above and beyond what Celgene does. Its MS-centric portfolio is worrying, but continued revenue from Rituxan and its diverse pipeline — particularly with the sky-high expectations for BG-12 — paint a picture of growing sales ahead. BG-12 could strip some of Avonex and Tysabri’s sales, and the MS market is a competitive one, but Biogen’s positioning itself well for a bright future.

In this battle between two big biotech stars, the edge just goes to Biogen. It’s hard to criticize any investor for picking up either of these stocks, however: Celgene and Biogen are positioned well in growing, lucrative markets, and their recent gains look to be the start of something special going forward.
