Stephen Mandel's Lone Pine Capital disclosed a new $512.07 million position in TTM Technologies, a major manufacturer of advanced printed circuit boards (PCBs) and radio frequency (RF) components. The stake, consisting of 2.74 million shares, now accounts for 3.13% of the hedge fund's reported portfolio. TTM Technologies is a key supplier for the aerospace, defense, data center, and automotive industries.
This investment was revealed in a quarterly 13F filing, which reflects holdings as of June 30, 2026, and does not indicate a current-day trade. The disclosure comes after a period of strategic activity for TTM, which in mid-August announced a definitive agreement to acquire Epiq Solutions, a provider of software-defined radios and RF products for mission-critical applications, for approximately $1.1 billion.
