The transaction is anticipated to be completed in the first half of 2022, assuming no regulatory or stockholder objections. Goldman Sachs and Qatalyst Partners are serving as financial advisors.

In 2018, Anaplan, which raised over $240 million in funding from Baillie Gifford, BlackRock, and other investors, listed on the New York Stock Exchange with the ticker “PLAN” and relocated its headquarters to San Francisco, California.

In the past 20 years, Thoma Bravo has made over 375 acquisitions or investments.

Holden Spaht, a managing partner at Thoma Bravo, stated that his firm has been following Anaplan, a leader in "connected planning," for several years.

Last week it emerged that activist investors had taken a stake in Anaplan.

Anaplan is the target of changes being pursued by a partnership between Keith Meister’s Corvex Management and Scott Ferguson’s Sachem Head Capital Management.

According to regulatory filings released on Thursday, Corvex and Sachem Head bought Anaplan shares because they saw them as undervalued and an attractive investment opportunity. Additionally, Jonathan Soros, a son of investor George Soros, joined in the buying spree through JS Capital Management.

Anaplan's outstanding shares are owned by about 9% by three firms, according to filings.

In February 2021, Anaplan's stock reached its peak, but it has since decreased by approximately 40% compared to its previous highs.

On Monday, the company's share price experienced a significant increase of over 25% to approximately $65 per share during pre-market trading.
