PACCAR builds Kenworth, Peterbilt and DAF trucks for businesses hauling goods on roads and off highway. Truck sales provide most of its revenue. Independent dealers buy substantially all its trucks, generally ordering them to customer specifications, and sell them to transport businesses. Demand depends on freight volumes and customers’ ability to fund new trucks.
PACCAR Parts is the next-largest revenue source. It sells replacement parts through Kenworth, Peterbilt and DAF dealers and TRP stores, earning from the margin on those sales. Demand depends on how many PACCAR trucks remain in service, their age and the mileage they cover.
A smaller business, PACCAR Financial Services, helps dealers fund truck inventories and helps trucking companies and owner-operators buy or lease vehicles. It earns interest and leasing revenue through PACCAR Financial and PacLease. Its earnings depend on customer payments, borrowing costs and used-truck values; collections from existing loans and leases and capital-market borrowing fund the business.
Truck production relies on outside suppliers, including Cummins for engines, Eaton and ZF for transmissions, and Magna for North American cab stampings. Losing these supplies could interrupt production. Emissions rules also shape what PACCAR can sell: European Union requirements call for lower carbon emissions and a significant share of zero- or near-zero-emission vehicles, with fines for missing the targets.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
PACCAR’s results hinge on commercial-truck demand and competition with Daimler Truck, Traton and Volvo/Mack—key rivals missing from this list.
PACCAR buys all the truck engines it does not make itself from Cummins, so engine supply and orders closely connect the two businesses. Cummins also sells engines to rival truck makers, making its heavy-duty engine orders a useful gauge of PACCAR’s production cycle, rather than PACCAR demand alone.
Rush Enterprises buys Peterbilt trucks and PACCAR parts to sell through its commercial-vehicle dealerships, giving PACCAR investors a direct view of dealer demand. Those truck and parts sales generated most of Rush’s 2025 revenue; watch them for demand for both new Peterbilt trucks and maintenance parts.
Allison sells fully automatic commercial-vehicle transmissions to PACCAR, so PACCAR’s purchases feed directly into Allison’s sales. PACCAR accounted for approximately 11% of Allison’s 2025 net sales, making purchases for trucks fitted with Allison transmissions the relevant signal.
Atmus supplies filters to PACCAR, and both earn materially from maintaining vehicles already in service; PACCAR accounted for 16.3% of Atmus’s 2025 net sales. Watch Atmus’s replacement-filter business for maintenance demand, which matters to PACCAR’s parts sales as its trucks age and accumulate mileage.
Dana supplies PACCAR with parts that transmit power through vehicles, linking its commercial-vehicle orders to PACCAR’s truck production; PACCAR was its fifth-largest customer in 2025. Watch Dana’s commercial-vehicle sales rather than total sales, since light vehicles generated 70% of its 2025 external sales.
PACCAR relies on Eaton for a significant share of its transmissions under long-term supply agreements, so a supply interruption could materially disrupt truck production. Eaton’s transmission supply to PACCAR is the news to watch for this tie.
PACCAR buys a significant portion of its North American cab stampings—the formed parts used to build truck cabs—from Magna International. Despite long-term supply agreements, losing that supply could materially interrupt PACCAR’s truck production, making continuity of cab-part deliveries the key issue to watch.
Old Dominion Freight Line’s shipment demand reflects the freight and industrial activity that supports PACCAR truck sales and fleet customers’ ability to pay. It earns primarily by carrying customers’ shipments too small to fill a truck, so watch that less-than-truckload demand for a read on U.S. industrial freight conditions.
Werner Enterprises’ freight business reveals conditions that affect PACCAR customers’ truck purchases and ability to repay truck financing. Werner earns from carrying truckload shipments for customers, including retail distribution centers and manufacturers; watch its truckload volumes and rates for the freight conditions behind those spending and repayment decisions.
Stoneridge supplies vehicle electronics and systems to PACCAR, one of its largest customers, so its commercial-vehicle business is directly tied to PACCAR production. Watch orders for its vehicle displays and control systems for a signal of truck makers’ production needs.
Core Molding Technologies sells molded structural parts to PACCAR, tying those orders directly to truck production. PACCAR generated 11% of its 2025 sales, making orders for molded truck parts the relevant business to watch.
Mayville Engineering Company makes components for PACCAR, its largest customer at 13.6% of 2025 net sales, so PACCAR’s production requirements matter directly to its results. Watch reductions or delays in PACCAR component orders, which can lower MEC’s sales and leave fixed costs spread over less revenue.
ArcBest’s customer freight demand tracks conditions that influence PACCAR truck orders and customers’ ability to repay financing. ArcBest earns from transporting and arranging shipments; watch demand for ABF Freight’s less-than-truckload service and MoLo’s truckload brokerage for a view of that freight market.
Aurora Innovation is helping PACCAR develop driverless-capable trucks by integrating its autonomous-driving technology into the Peterbilt 579 and Kenworth T680. Aurora sells a driverless trucking subscription service; watch progress integrating that technology into these two PACCAR models.
Paccar Inc earningsThis company
PACCAR’s report will show whether parts and financing can keep cushioning its business as fewer new trucks are delivered.
Read Truck revenue and pre-tax margin alongside Parts revenue and pre-tax margin, then check Financial Services revenue and pre-tax income. Steady parts sales and margins with continued finance income would show that aftermarket demand from trucks in service and financing are cushioning fewer new-truck deliveries; falling parts revenue or margins and weaker finance income would mean that cushion is thinning and the truck downturn is weighing more heavily on PACCAR.
Rush Enterprises Inc earningsRUSHA
Rush Enterprises’ report will show whether its dealerships are selling Peterbilt trucks and parts steadily, a direct read on demand for PACCAR’s new trucks and aftermarket business.
Read Rush Enterprises’ new-truck sales alongside its parts sales. Strength in both would show that dealer demand for Peterbilt trucks and for maintaining vehicles already in service is supporting PACCAR; weak truck sales with steady parts sales would point to deferred replacement but continuing maintenance demand; weakness in both would signal pressure on PACCAR’s new-truck and aftermarket businesses.
Fed Interest Rate Decision
The Fed’s policy rate sets a key benchmark for borrowing costs; it can change what PACCAR Financial Services pays to fund truck loans and leases and what it earns from customers.
Expected4.0%Last release4.0%
If it comes in above expectations
Higher rates can raise the cost of PACCAR Financial Services’ commercial-paper, note and bank-debt funding, squeezing the spread between funding costs and customer loan and lease income; pricier customer borrowing may also curb financing demand.
If it comes in below expectations
Lower rates can ease PACCAR Financial Services’ funding costs and widen the spread on loans and leases if customer income adjusts more slowly; cheaper borrowing may also support dealers’ and customers’ financing demand.
Magna International earningsMGA
Magna International’s report will show whether its North American cab stampings are reaching PACCAR, since a supply disruption could interrupt truck production.
Look for Magna’s comments on commercial-vehicle supply, especially whether deliveries of North American cab stampings to PACCAR remain continuous. Steady deliveries mean PACCAR has a key input to keep building trucks; a disruption or delay could force PACCAR to slow production despite long-term supply agreements, making continuity the key test of truck output.
Cummins Inc. earningsCMI
Cummins’ report will show heavy-duty engine demand across truck makers and supply to PACCAR, which buys from Cummins the truck engines it does not make itself.
Read Cummins’ heavy-duty engine orders together with its supply and delivery commentary. Steady orders and deliveries would indicate ongoing truck-production demand and available engines for PACCAR; weaker orders, especially across other truck makers, would point to pressure on the broader production cycle rather than PACCAR alone; supply disruption could constrain PACCAR even if demand is there.
Industrial Production MoM (Oct)
Industrial production measures output from factories, mines and utilities, while capacity use shows how much available production capability is being used; stronger activity can tighten component supply and constrain PACCAR’s ability to build trucks for its independent dealers.
If output and capacity use are strong, read it as a sign that component demand may strain suppliers serving PACCAR and automakers, potentially limiting truck production and dealer deliveries; if they are weak, supply pressure may ease, though demand for PACCAR trucks may also soften.
