The details

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. Defendants allegedly used the Proxy to intentionally mischaracterize Smartsheet's financial success and performance during and in the context of Smartsheet's sales process, casting the company's quarterly earnings in a negative light and emphasizing a financial metric apparently made up just for the purposes of soliciting approval for the buyout.

  • The buyout of Smartsheet by Blackstone, Vista Equity Partners, and Platinum Falcon occurred in January 2025.
  • The deadline for Smartsheet investors to join the securities class action lawsuit as lead plaintiff is February 24, 2026.

What they’re saying

“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.”

— Laurence Rosen, Founding Partner, Rosen Law Firm (Rosen Law Firm)

What’s next

To join the Smartsheet class action, investors must move the Court no later than February 24, 2026 to serve as lead plaintiff.

The takeaway

This case highlights the importance for investors to carefully select qualified legal counsel with a proven track record when participating in securities class action lawsuits, as opposed to firms that may simply be referring clients or partnering with other law firms.
