10-KFY2023

Pursuant to authoritative accounting guidance, Cercacor is consolidated within our financial statements for all periods presented.

Through the second and third quarters of 2023, we expanded these actions by streamlining operations, including the consolidation and rationalization of business activities and facilities, workforce reductions, suspension of incentive bonus compensation and annual salary adjustments, transfers of product lines between manufacturing facilities, and the transfer of other business activities between facilities.
