Activist hedge fund Jana Partners has quietly acquired a new stake in technology company Everpure and is expected to soon disclose that position through a regulatory filing, according to two sources familiar with the matter and documents reviewed by Reuters.
The New York-based hedge fund began accumulating shares during the first quarter of 2026. However, it did not include the holding in its standard 13-F quarterly disclosure form because it had obtained what is known as “confidential treatment” — a temporary delay in reporting the position to U.S. regulators.
By the close of the first quarter, Jana Partners held more than 1 million shares in Everpure, which is headquartered in Santa Clara, California. The sources, who are not authorized to speak publicly about the fund’s holdings, could not confirm the current size of the stake.
It also remains unknown what specific changes the hedge fund — led by managing partner Scott Ostfeld — may be pushing for at the company.
Everpure, which was previously named Pure Storage, rebranded in early 2026 to reflect its evolution from a data storage provider into an artificial intelligence-focused data management and intelligence platform. The company has benefited from surging demand tied to AI infrastructure growth and increased appetite for data services.
The company carries a market value of $23 billion, and its stock has risen 2.35% so far this year. Everpure also surpassed Wall Street earnings expectations for its fiscal first quarter, which wrapped up in May.
Activist investment firms sometimes seek confidential treatment to give themselves more time to build a position without tipping off competitors who might otherwise jump ahead of their trades. Berkshire Hathaway is a well-known example of a firm that regularly requests such treatment from the U.S. Securities and Exchange Commission while still accumulating shares.
A spokesperson for Jana Partners did not respond to a request for comment. A representative for Everpure offered this statement: “We maintain an open dialogue with all shareholders and we remain focused on executing our strategic plan and delivering for our customers and investors.”
Jana Partners is widely regarded as one of the more successful activist investment firms on Wall Street, and its investment decisions are closely watched by bankers and investors alike. Among its past campaigns, the firm pushed telecom company Frontier Communications to pursue a sale, which eventually led to its acquisition by Verizon Communications.
Jana is also currently pressing fintech payments company Fiserv to divest non-core businesses and bring fresh faces onto its board of directors.
