As previously disclosed, on February 14, 2024, Masimo Corporation (?Masimo?) initiated a voluntary recall of select Rad-G products in connection with an issue that can result in an unintentional change in the power state of the device. Masimo previously reported that in the first quarter of 2024, it received a subpoena from the Department of Justice (?DOJ?) seeking documents and information related to Masimo?s Rad-G and Rad-97 products, including information relating to complaints surrounding the products and Masimo?s decision to recall the Rad-G, and a civil investigative demand from the DOJ seeking documents and information related to customer returns of its Rad-G and Rad-97 products, including returns related to its recall of select Rad-G products in 2024. At an investor conference on June 5, 2024, in response to a panelist?s question, a representative of Masimo made certain statements about the product recall.

Masimo is hereby correcting the statements by clarifying that approximately 7,350 Rad-G units sold in the U.S. are subject to the recall, and approximately 20,250 Rad-G units sold outside the U.S. are subject to the recall. Masimo will continue to cooperate with the government in connection with responding to the subpoena and the civil investigative demand and any related investigation or any other future requests for information, but makes no statement about the resolution of the government?s review or the timing thereof.
