NEW YORK, Jan. 12, 2026 /PRNewswire/ --

Why: Rosen Law Firm, a global investor rights law firm, reminds all former stockholders of Smartsheet Inc. (NYSE:SMAR) in connection with the January 2025 sale (the "Merger" or "Buyout") of Smartsheet to affiliates of investment funds managed by affiliates of Blackstone Inc. (collectively "Blackstone"), investment funds managed by Vista Equity Partners Management, LLC ("Vista Equity Partners" or "Vista"), and Platinum Falcon B 2018 RSC Limited, an indirect wholly owned subsidiary of the Abu Dhabi Investment Authority, which participated as an indirect minority investor in Smartsheet ("Platinum Falcon," and together with Blackstone and Vista, the "Consortium"), of the important February 24, 2026 lead plaintiff deadline.

So What: If you are a former Smartsheet stockholder, you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

What to do next: To join the Smartsheet class action, go to https://rosenlegal.com/submit-form/?case_id=49166 or call Phillip Kim, Esq. toll-free at 866-767-3653 or email case@rosenlegal.com for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than February 24, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

Why Rosen Law: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually litigate securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved, at that time, the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.

Details of the case: The complaint alleges that in connection with Smartsheet's solicitation of stockholder approval of the Buyout, defendants issued and filed with the SEC a false and misleading Schedule 14A Proxy statement, as amended (the "Proxy"). Defendants used the Proxy to intentionally mischaracterize Smartsheet's financial success and performance during and in the context of Smartsheet's sales process. Specifically, defendants deliberately cast Smartsheet's quarterly earnings in a negative light in the Proxy, and emphasized a financial metric that it apparently made up just for the purposes of soliciting approval for the Buyout. Additionally, it was alleged that defendant Mark P. Mader failed to use reasonable care in the fulfillment of his disclosure duties.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
