Pfizer considers bolstering its oncology standing through $30B Seagen acquisition

Big Pharma giant Pfizer (NYSE:PFE) is reportedly in talks to acquire Seagen (Nasdaq:SGEN).

Founded in 1998, Seagen — formerly known as Seattle Genetics — helped pioneer a cancer therapy known as antibody drug conjugates that work like a guided missile attacking tumors with toxic agents.

Last year, Segan installed David Epstein as its CEO after its co-founder and former leader Clay Siegall resigned after an arrest.

In 2022, Seagen raked in almost $2 billion in revenue, which equated to an almost a quarter increase over the prior year.

Seagen has a market value of some $30 billion. An acquisition would likely command a premium over that figure, according to The Wall Street Journal.

Pfizer isn’t the first company with recent plans to acquire Seagen. In 2022, executives at Seagen were considering talks with Merck & Co. (NYSE:MRK) over a proposed $40 billion acquisition deal. Those talks, however, fell apart.

Merck moves forward with Seagen acquisition plans 

Executives from Merck & Co. (NYSE:MRK) and Seagen (Nasdaq:SGEN) are reportedly considering a $40 billion acquisition deal.

Readington, New Jersey–based Merck has offered to spend about $200 per share for Seagen, according to The Wall Street Journal.

Executives from the company aim to finalize the deal before Merck announces its Q2 earnings on July 28, according to WSJ.

Seagen shares were up about 2%, trading at $178.56 in afternoon trading.

Merck shares held steady, hovering around $92.90.

In a Q1 earnings call, Merck CEO Robert M. Davis said the company is working to diversify its business as it plans to lose exclusivity for its megablockbuster immunotherapy drug Keytruda. “In oncology, we remain committed to building on the foundational position that we have achieved with Keytruda, and we aim to expand our presence in this key therapeutic area and to establish an enduring leadership position,” Davis said.

Merck reportedly mulling Seagen acquisition

Approximately one month after Seagen (Nasdaq:SGEN) CEO Clay Siegall resigned following a domestic abuse arrest, Merck & Co. (NYSE:MRK) is considering purchasing the company, according to WSJ.

One potential hurdle is the possibility of increased antitrust enforcement from the DOJ and FTC focused on the pharmaceutical sector.

To sidestep such risks, the two companies could enter a joint marketing arrangement instead, according to the WSJ article, which cited anonymous sources. The two companies have already had strategic collaborations in oncology.

Investors reacted to the news by sending SGEN shares up almost 13% to $165.45.

Merck shares were mostly flat, closing at $84.62.

Last year, Merck generated $48.7 billion in revenue. More than one-third of it, however, came from the immunotherapy drug Keytruda (pembrolizumab). Keytruda patent protections are set to expire in 2028.

Seagen had $1.6 billion in revenue in 2021.

Tivdak from Genmab and Seagen wins accelerated approval for metastatic cervical cancer indication

The FDA has granted accelerated approval to the first-in-class antibody-drug conjugate Tivdak (tisotumab vedotin-tftv) from Genmab and Seagen to treat adults with recurrent or metastatic cervical cancer. Specifically, the approval covers cancer with disease progression on or after chemotherapy.
