CriticalPoint Advises PLX, Inc. on its Sale to Luxium Solutions, a portfolio company of SK Capital Partners and Edgewater Capital Partners

May 14th, 2024 – CriticalPoint is pleased to announce that it represented PLX, Inc. and PLX UK, Ltd. (collectively, “PLX” or the “Company”), a leading designer and manufacturer of high-precision optical assemblies and products, on its sale to Luxium Solutions, LLC (“Luxium”), a portfolio company of SK Capital Partners, LP (“SK Capital”) and Edgewater Capital Partners, LP (“Edgewater”).

Headquartered in Deer Park, NY, PLX designs and manufactures high-precision optical assemblies and products for the defense and aerospace sectors, as well as other industries. PLX’s solutions are deployed in a range of harsh environments and high-end applications where structural integrity and accuracy over time are critical, such as Military Fire Control Systems, Bore Sighting, Beam Alignment and Delivery Systems, Laser Tracking, Environmental Monitoring, Metrology, and Satellite Ranging. PLX’s proprietary and patented Monolithic Optical Structure Technology (M.O.S.T.TM) integrates complex optical elements into compact monolithic structures, achieving exceptional accuracy and stability under severe environmental conditions. PLX has been majority-owned since 2019 by an investor group led by Tinicum L.P., a private investment firm based in New York that manages a diversified group of manufacturing, distribution, and industrial technology companies.

Luxium is a worldwide technology leader and provider of high-performance crystals used in photonics and radiation detection applications. The partnership with PLX broadens Luxium’s offering of Detection Enabling Technologies by enhancing its suite of photonics assembly solutions which are complemented with high-end optical engineering and design services. PLX is Luxium’s first acquisition since its 2022 investment by SK Capital and Edgewater, both private investment firms focused on the specialty materials and chemicals sectors.

“We believe Luxium is the right partner for PLX in its next phase of growth. Luxium and PLX share a strong alignment in their go-to-market strategies emphasizing collaboration with customers to develop customized solutions. Furthermore, it’s clear that both companies share common values grounded in scientific excellence, quality, and customer satisfaction,” said Itai Vishnia, CEO of PLX, who will continue to lead the PLX group within the Luxium portfolio.

“I want to thank CriticalPoint for their incredible job advising PLX on its sale to Luxium,” said Mr. Vishnia. “Their deep experience and thoughtful advice throughout the M&A process were invaluable. We are excited for the next phase of PLX’s future as part of Luxium.”

CriticalPoint served as the exclusive financial advisor to PLX in connection with the deal. The transaction, led by Matt Young and Chris Kim on behalf of CriticalPoint, demonstrates the firm’s expertise in middle market transactions and commitment to act as a trusted advisor with proven abilities to deliver for its clients.
