Solothurn, Switzerland Manufacturing Facility In order to support our future growth and drug development pipeline, we are building a large-scale biologics manufacturing facility in Solothurn, Switzerland. Upon completion, this facility will include 393,000 square feet related to a large-scale biologics manufacturing facility, 290,000 square feet of warehouse, utilities and support space and 51,000 square feet of administrative space. As of March 31, 2023 and December 31, 2022, we had approximately $721.2 million and $711.1 million, respectively, capitalized as construction in progress related to this facility. Solothurn has been approved for the manufacture of ADUHELM and LEQEMBI by the FDA. In the second quarter of 2021 a portion of the Solothurn manufacturing facility was placed into service and we estimate the second manufacturing suite will be operational by the end of 2023.
