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.
