We are dependent upon outside suppliers for our raw material needs, other purchased component parts, and chassis. Prices, availability and the timing of delivery of these raw materials, purchased component parts, and chassis are subject to substantial fluctuations that are beyond our control due to factors such as changing economic conditions, the level of tariffs that the U.S. impose on imported steel, aluminum, and other commodities or component parts and any resulting trade wars or trade restrictions, inflation, governmental regulations (including CARB's Advanced Clean Trucks regulation), currency and commodity price fluctuations, resource availability, transportation costs, weather conditions and natural disasters, political unrest and instability, war (such as the ongoing military conflicts in Ukraine and the Middle East) and other factors impacting supply and demand pressures. Sporadic deliveries, significantly elevated delivery quantities, and delays in shipments of our raw materials, purchased component parts, including chassis, and government actions related to tariffs on imports and trade policies have previously adversely impacted, and have the potential to further impact our revenues, results of operations and financial condition.
As a result of our supply chain challenges, it has become more difficult to accurately forecast, purchase, warehouse, and transport to our manufacturing facilities and to our distribution partners purchased materials, component parts, and chassis at optimal volumes. If we are unable to accurately match the timing and quantities of component purchases, including chassis, to our actual needs or successfully manage our inventory or our workforce to adapt to the increased complexity in our supply chain, we may incur unexpected inventory buildup in our distribution channel. A mismatch in the timing and quantities of component purchases, including with respect to chassis, that results in a significant inventory buildup in our distribution channel has resulted, and could continue to result, in reduced sales, as our distribution partners work through any such inventory buildup in the field. In addition, if we experience shortages or delays in receiving raw materials, component parts, and chassis, we may also incur unexpected production disruption, as well as storage, transportation, and labor costs, which could have a material adverse effect on our financial condition and results of operations. In addition, we may not be able to meet our customers' delivery schedules and could face the loss of orders or customers as a result of any resulting production disruptions.
Our third-party suppliers' ability to supply us with component parts and chassis is limited by their available capacity to manufacture the component parts and chassis we require, and to secure adequate freight capacity to deliver them to our facilities. Various supply chain disruptions in 2024 continued to impact our ability to obtain certain raw materials, purchased component parts and chassis from third party suppliers resulted in substantial price increases. In addition, in the fourth quarter of 2023 and during 2024, we and, in turn, our distribution partners, also experienced significantly elevated levels of chassis shipments earlier than expected that resulted in a buildup of inventory in our distribution channel during the first half of 2024. While we slowed chassis deliveries in the second half of 2024 to allow our distributor network to work through the inventory already in the distribution channel, we continued to experience such difficulties throughout 2024 and in early 2025. These supply chain difficulties have had, and are anticipated to continue to have, a material adverse impact on our profitability and results of operations.
Delays in deliveries of our finished products due to delays of purchased component parts and chassis used in our products could also adversely affect future demand for our products if our customers reduce their purchase levels with us and/or seek alternative solutions to meet their demand. If these delays, limitations on availability and price increases for raw materials, purchased component parts, and chassis continue, recur or worsen, they will continue to have a material adverse effect on production at our facilities.
Recently, the U.S. announced the implementation of new or increased tariffs, including tariffs on steel and aluminum products imported from various countries. The ultimate impact of these tariffs is unknown at this time. Additionally, ongoing changes in U.S. and foreign government trade policies, including potential modifications to existing trade agreements and further restrictions on free trade, could introduce additional uncertainty. Any escalation of trade tensions, additional tariffs, retaliatory measures by foreign governments, or shifts in U.S. or international trade policies could adversely impact our supply chain and increase costs of component parts, chassis and raw materials, such as steel, aluminum, and petroleum-related products. A trade war or other significant changes in trade regulations could have an adverse effect on our business and results of operations. We also continue to monitor the impact of the conflict in Ukraine and the Middle East on our fuel costs and supply chain for materials and component parts, particularly with respect to steel and items with substantial steel content.
Shortages and price increases and/or delays or unexpected cadence or quantities in the deliveries of, our raw materials and purchased component parts, including chassis, have had and should be anticipated to continue to have a material adverse effect on our profitability, financial performance, competitive position and reputation.
