Overview	NOTE 1. OVERVIEW Overview Allison Transmission Holdings, Inc. and its subsidiaries (“Allison” or the “Company”) design and manufacture vehicle propulsion solutions, including commercial-duty on-highway, off-highway and defense fully automatic transmissions and electric hybrid and fully electric systems. The business was founded in 1915 and has been headquartered in Indianapolis, Indiana since inception. Allison trades on the New York Stock Exchange under the symbol “ALSN”. The Company has approximately 3,500 employees. Although approximately 74% of revenues were generated in North America in 2022, the Company has a global presence by serving customers in Asia, Europe, South America and Africa. The Company serves customers through an independent network of approximately 1,600 independent distributor and dealer locations worldwide. Global markets continue to experience supply chain, labor, energy and raw material constraints as a result of global economic volatility, the war in Ukraine and the COVID-19 pandemic, that impacted the Company's business in 2022 and continue to impact its business performance. As a result, during 2022 the Company experienced raw material and component part price inflation, increased freight and logistics costs, increased labor costs, production constraints due to labor shortages and increased foreign exchange volatility. In addition, the Company's net sales for 2022 were negatively impacted as a result of its customers’ inability to secure components from the broader commercial vehicle supply base which resulted in reduced commercial vehicle build schedules and the inability of the commercial vehicle market to produce sufficient quantities to meet demand. The Company expects that commercial vehicle build schedules will continue to be negatively impacted by the availability of components in 2023.
