I. Basics

Summer Road LLC is an activist investment firm that focuses on shareholder‑engagement campaigns and corporate‑governance initiatives, typically targeting companies where it sees underperformance, misaligned incentives, or governance weaknesses. 

David Sackler is the president and head of Summer Road LLC, a New York–based single‑family office that manages part of the Sackler family’s wealth, derived from the former Purdue Pharma fortune. He is the grandson of Raymond Sackler, co‑founder of Purdue Pharma, and served on Purdue’s board from 2012 to 2018 before shifting his focus to finance and private investing. With a background in hedge‑fund–style investing—having worked at firms such as Perry Capital and OSS Capital and later leading Moab Partners—Sackler now oversees Summer Road’s portfolio, which spans private equity, hedge‑fund partnerships (such as the Balter Long/Short Equity Fund), and various alternative‑asset strategies for the Richard Sackler family.
