Key developments

In 2024, RIBER achieved its revenues targets, driven by solid growth in MBE system sales. This momentum reflects
the strengthening of its positions in the MBE market, for both research and industrial production, as evidenced
by the strong order intake during the year, with 13 new MBE systems. In this context, the company's earnings
show a clear improvement compared with the previous year.

Alongside this, RIBER moved forward with its innovation efforts with the development of ROSIE (RIBER Oxide on
SIlicon Epitaxy), a new system dedicated to the silicon photonics sector. Designed to meet the growing
demands of optical transmission and reception applications, its commercial launch, scheduled for 2026,
opens up new prospects in a fast-growing market. This dynamism is supported by the demand for advanced
semiconductor materials dedicated to data transmission and Artificial Intelligence. The techn ology
developed by RIBER will help reduce energy consumption, particularly in data centers.

Revenues

Full-year revenues for 2024 increased to €41.2m, up +5% from 2023. Revenues for MBE systems were up +7% to
€31.0m for 12 machines delivered, compared with 13 in 2023. Revenues for services and accessori es
amounted to 10.2 million euros, representing 24.8% of 2024 revenues, and were broadly stable year-on-year.

Earnings

The gross margin was €14.8m, up +12.1%, driven by growth in system business.

Income from ordinary operations was €4.5m, up +14.4% compared with the previous year, thanks to effecti v e
control of operating costs. It represents 11% of revenues, compared with 10% in 2023.

Net income totaled €4.1m, compared with €3.4m in 2023, an increase of +21.4%.

Cash flow and balance sheet

The cash position at end-2023 was positive at €8.6m, compared to €9.7m at end-2023.

Shareholders’ equity totaled €23.6m, up +€2.3m compared with end-2023. This change is driven by the
earnings for the year 2024 and the distribution of amounts drawn against the issue premium for 2023 to
shareholders.

Order book

The order book at December 31, 2024 represented €21.7m, down 17% year-on-year, including 7 MBE systems
(€16.7m), of which 5 for production, as well as orders for services and accessories (€5.0m).

The order book is up after factoring the two new orders announced in January 2025 for a production system
in Europe and a research system in the United States, both scheduled for delivery in 2025.

Outlook

In view of the uncertainties linked to the application of US customs duties and the economic environment,
RIBER is reserving its position on issuing guidance for fiscal year 2025.

RIBER remains committed to its medium-term objectives. In this context, RIBER is moving forward with its growth
strategy by strengthening its technological leadership and expanding its solutions into new high value-added
markets, particularly silicon photonics and materials for quantum technologies. These developments will be
presented at the next Annual General Meeting on June 18, 2025.

Distribution of amounts drawn against the “issue premium” account

The Board of Directors will propose to the June 18, 2025 General Meeting a cash distribution of €0.08 per share,
through a partial reimbursement of the issue premium. It will be released for payment on June 25, 2025.

Next dates

• April 18, 2025 - 6:00pm: 2024 annual financial report
• June 18, 2025 - 10:00am: General Meeting in Paris

The annual financial statements were approved by the Board of Directors on April 8, 2025. The statutory
auditors have completed the audit procedures on the corporate and consolidated accounts. The
certification report will be issued once the necessary procedures have been finalized for publishing the full -
year financial report.

In compliance with AMF regulations and the operating rules of Euronext Growth Paris, RIBER will henceforth
publish its sales figures on a half-yearly basis, except in the event of significant developments.
