REC Silicon Qualification Material of Ultra-High Purity Polysilicon Clears Customs

15 Nov 2024 18:20 CET

Moses Lake, Washington USA - November 15, 2024: REC Silicon ASA ("REC Silicon"
or the "Company") provides an update concerning the qualification process for
its ultra-high purity polysilicon from the recently restarted silane-based
high-purity granular production facility in Moses Lake, Washington.

As reported on October 21, 2024, qualification material of ultra-high purity
polysilicon was delayed with unexpected procedures by customs in the country
where the qualification testing will be performed. The qualification material
cleared customs and is now available for the third party to test.

Although the testing is expected to commence soon, the exact schedule is
contingent upon the third party's own production schedule. The Company
continues to work with the customer to determine the new schedule and where
possible expedite the qualification test. The Company does not expect to
receive the results of the qualification test for a minimum of four weeks but
will provide further information as it becomes available.

The qualification process must be completed successfully before the Company is
able to make its first shipment of product with a modified specification. As
with any qualification process of this sort, the outcome of the testing and
hence our ability to deliver product within a certain timeframe, remains a
risk.

As a leading producer of silane gases and silicon materials, REC Silicon is
well positioned to capitalize on the global megatrends of digitalization,
energy transition and energy storage. The Company has developed a strong
market position in the Semiconductor industry based on its operations in
Butte, Montana. The successful restart of Moses Lake operations will enable
REC Silicon to provide ultra-high purity polysilicon to the US solar value
chain currently under construction while the Company also expects to supply
silane gas in significant volumes for anode materials to a fast-growing
battery industry.
