April 1 (Reuters) - Kimmeridge Energy Management said on Monday that it remained ready to engage with SilverBow Resources over its takeover offer for the U.S. oil and gas producer.

SilverBow last week rejected the offer from Kimmeridge, its top shareholder, that valued the company at $2.1 billion.

Kimmeridge in an open letter said SilverBow did not contact the firm before rejecting the March 13 proposal. (Reporting by Vallari Srivastava in Bengaluru; Editing by Sriraj Kalluvila)
