On January 13, 2022, Zendesk Inc. reiterated the benefits of its proposed acquisition of Momentive Global Inc. and asked shareholders to vote in its favor, right after 2 activist investors, Janus Henderson Investors and Jana Partners, opposed the deal. In a letter to shareholders, the Company restated mostly only synergies that were disclosed earlier about the all-stock deal to buy Momentive. The Company stated that it has increased conviction in the upside and the expected synergies of the deal which is expected to close in the first half of this year.

The Company also recommended its stockholders to vote for the proposal to approve the issuance of shares of the Company's common stock to Momentive stockholders in connection with the transaction at upcoming special meeting of stockholders scheduled to be held on February 25, 2022.
