Background & Opportunity
THEON sells night-vision, thermal-imaging, and electro-optical systems to governments, armed forces, and defense prime contractors. Its revenue model extends beyond individual system sales to include long-term framework contracts, localized international production, and after-sales support. In this model, winning an order is only the first step. The ability to obtain critical components on time and complete delivery determines how quickly an order can be converted into revenue. Image intensifier tubes are among the most important and expensive components in night-vision equipment. As demand to modernize night-vision capabilities increased across Europe and the United States, THEON’s market opportunity expanded. Yet limited spare capacity across the global supply base meant that component availability could also become a constraint on growth. THEON generated revenue of €218.72m in 2023, giving it a solid commercial base for its subsequent expansion. Before 2024, however, THEON purchased image intensifier tubes more frequently through ad hoc orders. That approach could support ordinary procurement requirements, but it made it harder to coordinate upstream production with THEON’s delivery schedule when demand accelerated. If critical components failed to arrive on time, the company could win more system orders while still being unable to expand output at the required pace. Delivery lead times could then lengthen even as the order book grew. Defense customers can also place unexpected orders that require rapid delivery. Reliance on ad hoc purchasing made it more difficult to align component arrival dates with these customer requirements. THEON was therefore confronting more than a conventional procurement-cost problem. It faced a structural mismatch among order growth, constrained component capacity, and its ability to deliver finished systems. The company needed to answer three related questions. First, how could it obtain multiyear capacity commitments from external suppliers? Second, how could inventory be used to prepare for orders requiring rapid delivery? Third, should THEON bring part of image intensifier tube manufacturing under group control? In February 2024, THEON’s IPO generated net proceeds of €93.9m, providing the financial foundation for acquisitions and growth investment. This capital allowed management to elevate supply security from a routine purchasing matter to a capital-allocation decision. THEON could now combine external long-term procurement with investment in upstream manufacturing. Each lever addressed a different part of the constraint. An external agreement could coordinate future production volumes and delivery schedules directly with a major supplier. Building inventory of critical components could improve readiness for unexpected large orders. Taking control of an upstream manufacturer could create partial in-house supply, although doing so would require investment in equipment upgrades and production-line expansion. THEON ultimately treated these approaches as complementary rather than mutually exclusive. The strategic objective was not to eliminate external suppliers entirely. It was to reduce the uncertainty created by depending on a single ad hoc purchasing model during a period of rapidly rising demand. Long-term external supply, inventory readiness, and partial control of production capacity together created a broader delivery safeguard. The limits of the conclusion are equally important. Rising European defense demand, a major OCCAR contract, new products, and geographic expansion also contributed to THEON’s performance. The supply chain strategy cannot be treated as the sole cause of all revenue growth. Its more precise role was to provide a critical operating condition that helped the company maintain rapid delivery and expand its business as demand increased.
Original Problem / Model
Before 2024, THEON purchased image intensifier tubes more frequently through ad hoc orders. With limited spare global capacity, a concentration of modernization demand and unexpected large orders could create shortages, lengthen delivery times, and disconnect growth in orders from the company’s ability to expand actual production.
Turning Point
In 2024, THEON made supply security a core strategy. It first secured a multiyear arrangement with Exosens, then acquired a 60% interest in Harder Digital, while using critical-component inventory to support orders requiring rapid delivery.
Core Decision
THEON decided to use IPO proceeds and its own cash for two layers of protection: reserving future capacity from an external supplier while investing in and controlling upstream manufacturing capacity.
Execution / Model / Acquisition Changes
The Exosens agreement covered 2025—2026 and included a 2027 option. On November 14, 2024, THEON acquired a 60% interest in Harder Digital for total purchase consideration of €32.308m. It also invested in equipment upgrades and expanded production lines in Germany and Latvia.
Measurable Results
Revenue increased from €218.72m in 2023 to €352.36m in 2024 and reached €443.5m in 2025. After investment, Harder Digital’s annual capacity rose from approximately 6,000 tubes to approximately 15,000 tubes. THEON absorbed approximately 66% of output, while Harder Digital also secured a €25m third-party order.
Lessons
The supply chain decision was not the sole cause of THEON’s growth. However, the case shows that when a critical component can restrict delivery, long-term agreements, appropriate inventory, and upstream control can work together as a stronger safeguard than continued reliance on ad hoc purchasing alone.
