CHARLESTON, W.Va. — Mylan and Pfizer Inc. will not close on combining Mylan and Pfizer-subsidiary Upjohn until the second half of this year.

The companies are changing the closing date because of the coronavirus pandemic.

“The primary focus of both companies remains the health and safety of their dedicated and valued employees who are working tirelessly towards completion of this transaction while also maintaining their responsibility to meet patient needs during this extraordinary time,” Mylan and Pfizer said in a press release.

Mylan and Pfizer announced last July the agreement to form the new company, to be named Viatris.

Mylan also decided to delay its extraordinary general meeting of shareholders related to the transaction from April 27 to June 30, which is also when the annual general meeting of shareholders is scheduled to take place.
