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

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

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.
