What Blue Bird Corp. told the SEC could break it.

Blue Bird's component supply chain is exposed to U.S. import tariffs: it states that tariffs increase the cost of components it and its suppliers purchase from Canada, China and Mexico, and that tariffs imposed during the second half of fiscal 2025 increased procurement costs for certain imported inventory (it raised bus prices partly to mitigate this). It cannot assure it can pass along all increased costs, particularly under fixed-price bus contracts, and notes the policies could expand to other countries. A quantified-geography, already-realized trade-policy/tariff exposure.

“the cost of components we and/or our suppliers purchase from Canada, China and Mexico, which have increased and/or could increase our cost to produce buses and purchase parts for resale. These enacted and/or proposed trade policies and tariffs could expand to other foreign countries in future periods.”

A large share of Blue Bird's electric and low-emission school-bus demand is underwritten by the EPA's Clean School Bus Program (CSBP). Successive rounds awarded roughly $865M, ~$1B, $800M and $965M to school districts to buy clean buses (mostly electric), and Blue Bird booked hundreds of orders from each round (over 500, 440+, 490+). Reductions in these governmental grants, subsidies or incentives would decrease the funds school districts and fleet customers use to offset bus prices, directly cutting EV/propane bus orders. A distinctive, quantified federal-subsidy demand dependence — a genuine policy-shock channel for the EV bus transition.

Blue Bird's bus cost structure is heavily exposed to raw-material prices. It generally purchases steel up to four quarters in advance at fixed prices but does not otherwise hedge steel or its other primary commodities — rubber, aluminum and copper — so price moves in these inputs can significantly impact operating margins. Management attributes recent cost-of-goods-per-unit increases partly to higher raw-materials costs from inflation. A specific, named multi-commodity dependence on a metals-intensive hardware manufacturer.

“We generally purchase steel up to four quarters in advance at fixed prices, but because we generally do not otherwise hedge steel or the other primary commodities we purchase (rubber, aluminum and copper), changes in prices of raw materials can significantly impact future operating margins.”

Blue Bird manufactures essentially all of its school buses at one campus in Fort Valley, Georgia (~1.5 million sq ft, including its integrated chassis and body plants and fabrication) and distributes parts from a single center in Delaware, Ohio. A disruption at the Fort Valley site — severe weather/natural disaster, fire, equipment failure, or labor action — would halt production and have a material adverse effect, with no alternative bus plant. This single-site manufacturing concentration is compounded by the company's sector/geographic concentration in the U.S. and Canada school-bus market. A real single-point manufacturing concentration.

“We manufacture school buses at facilities in Fort Valley, Georgia and distribute parts from a distribution center located in Delaware, Ohio.”
