Cancer-drug maker Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX) recently rejected an $8.7 billion unsolicited acquisition offer from Amgen, Inc. (NASDAQ:AMGN). Onyx also said that it is looking for potential suitors. The move has triggered speculations of a bidding war, sending the stock up 51.27% on Monday to $131.33.
Amgen, Inc. (NASDAQ:AMGN) had offered to pay $120 per share in cash, a 38.2% premium to Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX)’s closing price of $86.82 on Friday, June 28. However, Onyx CEO Dr. Tony Coles felt that Amgen’s bid significantly undervalued his firm.
Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX) makes cancer drugs that generate high margins. It has liver- and kidney-cancer drug Nexavar, colon-cancer drug Stivarga and the newly launched Kyprolis. Analysts believe annual sales of Kyprolis could reach $3 billion. The peak sales of Nexavar and Stivarga could reach $1.4 billion and $1 billion, respectively. While Nexavar is established in the market, the other two drugs are yet to reach their sales peak. Onyx also has several promising drugs in the pipeline.
Large pharmaceutical companies have been eyeing cancer drugs because they require small sales forces and are usually covered by medical insurers. The potential acquirer has to take a bullish view on the future sales of Nexavar and Kyprolis. Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX)’s breast cancer molecule palbociclib has also showed promising results. The company has licensed palbociclib to Pfizer, for which it would get an 8% global royalty when the product hits the market.
Amgen, Inc. (NASDAQ:AMGN) plans to expand its business overseas and add new products to its portfolio as sales of its blockbuster drugs Aranesp and Epogen continue to decline. These two anemia drugs generated about $4 billion in sales in 2012. Moreover, some of Amgen’s major drugs will witness patent expiry starting 2015.
Amgen, Inc. (NASDAQ:AMGN) is planning to launch as many as six biosimilars by 2017. Kyprolis could complement Amgen’s product portfolio of cancer drugs and benefit from Amgen’s sales and marketing infrastructure. However, equity research firm ISI Group says that the $120-per-share share offer could work for Amgen only if it can attain 75% cost savings in sales and administration and 25% in R&D. That kind of cost savings looks impossible, given Amgen’s lack of experience in the hematological cancer market. And Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX) has already rejected the $120 offer, so raising the bid would put further pressure on Amgen. If you are an Onyx shareholder, you shouldn’t pin much hope on Amgen.
After the rejection of Amgen, Inc. (NASDAQ:AMGN)’s unsolicited offer, there have been reports that large pharmaceutical companies are gearing up to enter the bidding war. Large firms are trying to boost their product portfolio and add new drugs to their pipeline as their major drugs go off patent. But I believe Bayer to be the best suitor for Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX).
Of Onyx’s $362 million revenues in 2012, 80% came from two drugs, Nexavar and Stivarga, sold in partnership with Bayer AG. Onyx Pharmaceuticals, Inc. (NASDAQ:ONXX) gets 20% royalty on the sales of Stivarga, and 50-50 profit split on Nexavar.
