REC Silicon Update on Moses Lake Production Facility Ramp Up

Moses Lake, Washington USA -- May 2, 2024: REC Silicon ASA ("REC Silicon" or

the "Company") provides an operational update for the recently restarted

silane-based high-purity granular production facility in Moses Lake,

Washington.

The Company continues its ramp-up activities by improving, optimizing, and

increasing the production capacity at the Moses Lake facility. As stated in

prior communications, the Company's restart of production capacity is

progressing in line with the expectation of achieving full capacity

utilization by the end of 2024.

Currently, most of the key quality measures for the product have been met.

Process clean-up, tuning and internal/external testing continue, and the focus

remains on achieving all key parameters necessary for the Company to make the

first commercial shipment of its high-purity granular polysilicon. The first

shipment of product was previously anticipated to occur in early Q2 2024, the

Company now expects that the first shipment will occur during Q2

2024. Additional details will be provided during the Q1 2024 financial

release.

As a leading producer of silane gases and silicon metals, 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.
