What were the deal terms?
Pfizer’s announced offer was $229 in cash for each Seagen share, subject to exceptions in the merger agreement, and approximately $43 billion in enterprise value. At the merger’s effective time, each outstanding Seagen common share was converted into the right to receive the cash consideration, subject to the agreement’s terms. Merger agreement
These figures describe different measures. Pfizer’s 2024 Form 10-K, reporting fiscal year 2023, listed $43.4 billion as cash paid for the Seagen acquisition, net of cash acquired. That accounting cash-flow figure is not the same as the approximately $43 billion announced enterprise value. Pfizer 2023 Annual Review

What did the acquisition mean for Seagen and Pfizer?
Seagen did not remain an independent public company after the closing: it became a wholly owned Pfizer subsidiary. Pfizer presented the acquisition as a way to strengthen its position in oncology. That was the company’s strategic rationale, not evidence by itself of later commercial performance or improved clinical outcomes.
In its December release, Pfizer quoted chairman and CEO Dr. Albert Bourla saying the completion of regulatory reviews “supports our belief that this transaction is good for patients in the battle against cancer.” This is Pfizer’s stated view, not an independently established outcome.
