QuidelOrtho Corporation provided earnings guidance for First Quarter ended March 29, 2026. For the quarter, the Company currently expects preliminary unaudited revenue, as reported, of $615 million to $620 million. This preliminary unaudited revenue was primarily driven by a weaker respiratory season, with U.S. Influenza-like Illness visits down by approximately 30% compared to the first quarter of 20251, along with slower China distributor sales that the Company believes is related to the proposed China National Health Security Administration ("NHSA") reimbursement rate reductions.

Additionally, certain EMEA orders were delayed by the Middle East conflict, negatively impacting first quarter revenue.
