The acquisition was blocked on Nov. 1 by a federal judge on antitrust grounds. 

Penguin was unable to convince Simon & Schuster to launch an appeal and extend their deal contract before it expires on Monday, the sources said.

Penguin will owe Simon & Schuster a $200 million break-up fee as a result of the transaction falling apart.

The sources requested anonymity ahead of official announcements this week.

Bertelsmann and Paramount did not respond to requests for comment.

The U.S. Justice Department had sued to stop the tie-up of the two publishers, which combined would have accounted for more than 25% of all print books sold in the United States this year.

Following the deal's collapse, Simon & Schuster's owner, Paramount Global, will be free to explore a sale of the publisher anew.

HarperCollins, which is controlled by News Corp, and Lagardere SCA's Hachette Book Group have previously expressed interest publicly in buying Simon & Schuster.

HarperCollins also unsuccessfully bid for Simon & Schuster when it was put up for sale by Paramount in early 2020.
