About HLD Europe SCA de droit luxembourgeois

HLD Europe SCA, governed by Luxembourg law, is an investment vehicle within the HLD group and a reference shareholder of Exosens. In Exosens’ governance structure, HLD Europe is represented by Salim Helou, who participates in the company’s oversight and monitoring bodies. Its role reflects the broader support provided by the HLD group to Exosens since 2021, a period during which the company accelerated its strategic transformation and international development. Exosens, formerly the Photonis group, has grown into a leading player in amplification, detection and imaging technologies, with operations across Europe and North America. Salim Helou holds degrees from École Polytechnique and Columbia University. He began his career at McKinsey & Company in 2011 before joining Murex in 2013 as a senior consultant and project manager. He then joined HLD in 2016 as a Managing Director, where he has been responsible for overseeing several portfolio companies, including Exosens, Aresia, CBG Acciai and MVG. This background gives him a combination of strategic, operational and investment-management expertise, particularly in industrial businesses with complex growth trajectories. At Exosens, HLD Europe acts as a long-term shareholder and governance partner. HLD supported the company’s transition into a larger technological platform focused on high-barrier markets, notably defense and industrial applications. Exosens states that it has been backed by HLD since 2021 and has continued expanding through both organic growth and acquisitions, while strengthening its manufacturing and R&D footprint. The company also went through major capital events, with HLD Europe remaining Exosens’ principal shareholder in 2025, holding a reference stake in the company’s capital. Overall, this profile reflects a governance approach centered on strategic support, financial discipline and long-term value creation.
