Meta is the parent company of Facebook, Instagram and WhatsApp. It is one of the largest companies to be targeted by an activist investor, with a market cap of nearly $1.5 trillion.

Meta was previously targeted by Brad Gerstner's Altimeter Capital in 2022. Gerstner pushed the company to trim down its head count in a letter titled "Time to Get Fit."

ValueAct has taken stakes in a number of other mega-cap companies, including Salesforce, Disney and Microsoft. Morfit has also pushed for change at other, smaller technology companies, including Spotify.
