- 1 - 2025 performance driven by production systems and the rollout of ROSIE Revenues of €40.3 million in line with guidance Order book at December 31, 2025: €26.9 million (+24%) Bezons (France), February 2 , 202 6 – 8:00 am (CET) – RIBER, a global market leader in MBE equipment for the semiconductor industry, is reporting its full-year revenues for 2025. Change in revenues €m 2025 2024 Change First half 10.7 13.7 -22% Second half 29.5 27.4 +7% Full year 40.3 41.2 -2% €m 2025 2024 Change Systems 30.9 31.0 - Services and accessories 9.4 10.2 -8% Full year 40.3 41.2 -2% 2025 full-year revenues amounted to €40.3 million, in line with the Company’s guidance. This performance reflects both the continued strong activity in production systems and the gradual ramp-up of ROSIE, the new MBE platform dedicated to silicon photonics. The first two ROSIE systems were ordered in 2025, confirming growing industrial intere st in MBE solutions compatible with 300 mm production lines. MBE systems revenues reached €30.9 million, stable compared with 2024. This corresponds to the invoicing of 12 machines, including 9 production systems, as well as the delivery of the first ROSIE platform. Revenue from services and accessories amounted to €9.4 million, slightly down year-on-year, due in particular to budgetary restrictions in the United States, but showed a recovery in the second half of the year (+8.5%). In 2025, the geographical breakdown of annual revenue evolved as follows: Europe, up year - on-year, accounted for 45.1% (vs. 35.7% in 2024), Asia for 39.7% (vs. 57.3%), and North America, also up year-on-year, for 15.2% (vs. 7.1%). These changes reflect increased diversification of the markets served.

- 2 - The MBE systems order book, up 22%, amounted to €20.3 million, corresponding to 6 systems, including 4 production machines and 1 ROSIE platform. It does not include the order announced on January 19, 2026 for a production system in Japan, scheduled for delivery in 2026. The services and accessories order book reached €6.6 million, up 31% compared with a favorable prior-year comparison base. Certain commercial opportunities, representing a cumulative amount of €4 million, were subject to export license refusals during the year. Outlook Against a backdrop of large -scale investment programs in artificial intelligence, data infrastructure and quantum technologies, RIBER benefits from a pioneering technological positioning at the core of the semiconductor value chain. For 2026, RIBER expects: • a continued strong demand driven by the need for MBE production systems for quantum dot lasers used in data centers; • the industrialization and gradual ramp -up of the ROSIE platform, a breakthrough technology in silicon-based integrated photonics, addressing high-potential markets. In 2026, the manufacturing of ROSIE 2, the dual-chamber version, as well as the availability - within the framework of the partnership with NQCP 1 - of the first samples of BTO/STO 2 thin films on silicon wafers for the scientific and industrial community, will represent a key milestone in RIBER’s technological roadmap. Given the visibility provided by its order book, and subject to obtaining the export licenses required to materialize the identified opportunities in its systems and services businesses, RIBER aims to achieve revenues growth compared with 2025. Next date : RIBER will announce its 202 5 full-year earnings on April 8, 202 6 (before start of trading).
