Corvex told Pandora to sell itself; SiriusXM first invested $480M, then bought it

In May 2016 Corvex Management, Keith Meister's activist fund, disclosed a 9.95% stake in Pandora Media, the internet-radio pioneer whose stock had fallen after 12 of its last 14 earnings releases. In an open letter Meister questioned founder-CEO Tim Westergren's on-demand streaming ambitions and demanded Pandora 'immediately engage an independent investment bank... including a thorough sales process.'

Pandora did not sell at once, but the pressure set the agenda. In June 2017 SiriusXM agreed to invest $480 million in Pandora preferred stock, taking three board seats in a recapitalization that replaced much of the old board. Westergren stepped down weeks later, and new CEO Roger Lynch sold the Ticketfly ticketing unit and refocused the company on its core ad-supported radio business.

The strategic courtship Corvex demanded ended where he wanted: in September 2018 SiriusXM agreed to acquire all of Pandora in an all-stock deal valued at about $3.5 billion, completed in February 2019. Pandora shareholders got a premium exit instead of a lonely war against Spotify and Apple Music.

Pandora got a $480M SiriusXM lifeline and three board seats in 2017, then a full $3.5B all-stock acquisition by SiriusXM, completed February 2019.

Pandora's stock declined after nearly every earnings report, making Meister's 'vote of no confidence' line stick.

The founder's return as CEO read as retreat from a sale, which galvanized the activist case.

SiriusXM's preferred investment gave Pandora cash and credibility while it fixed the core business.

Once the portfolio was cleaned up, a full sale to SiriusXM was the logical endgame.

When a founder's vision no longer commands investor confidence, an activist ultimatum can convert a slow fade into a strategic exit on decent terms.

Pandora became a SiriusXM subsidiary in February 2019. The ad-supported service kept operating under its brand, and the deal gave SiriusXM the streaming footprint it lacked. Corvex's campaign, opened with a demand for a sale, closed with one roughly 33 months later.
