The $16 billion deal, which was announced in April, came after the companies partnered in 2019 to automate healthcare administrative work, such as documentation.

Nuance said in a filing to the U.S. Securities and Exchange Commission on Friday that the deadline for the U.S. government to object to the deal had expired on June 1.

That expiration "satisfies one of the conditions to the closing of the merger," the company said in the filing.

A spokesperson for Microsoft said in a statement that the deal was undergoing regulatory reviews in other jurisdictions and was intended to close at the end of 2021.
