Immatics Biotechnologies GmbH, of Tuebingen, Germany, and Arya Sciences Acquisition Corp. plan to merge as Immatics NV. Immatics will receive gross proceeds of up to $252 million at closing, which is expected in the second quarter of 2020.

Calling the tie "magic," Pfizer Inc. CEO Albert Bourla defended his firm's decision to spin off its Upjohn unit and merge in an all-stock deal with Mylan N.V., creating a new entity to be named later with pro forma revenues as high as $20 billion. "We have a commercial footprint that is very much focused on China, on emerging markets," he said, which will help Mylan.

Keeping with the trend of high-value biopharma deals, the second quarter of 2019 logged another eight partnerships worth $1 billion or more, with Gilead Sciences Inc. a party to three of them.
