The North American Class 8 truck market endured month-over-month declines in August but enjoyed strong year-over-year gains, according to preliminary net order data from ACT Research and FTR Intel.
Both firms reported the sequential pullback is not a sign of weakening demand. Instead, they attributed the drop to typical summer seasonality, the conclusion of the 2026 order season, and completely full 2026 build slots restricting further order intake before 2027 order boards officially open.
Demand meets ‘oversubscribed’ backlogs
ACT reported August Class 8 orders of 16,800 units (19,600 seasonally adjusted), representing a 31% year-over-year increase despite a 35% month-over-month decline.
The firm attributed the sequential drop to full build slots rather than weak demand, noting that July data showed second-half 2026 backlogs exceeded capacity by roughly 35,000 units, leaving virtually no room for new orders. Additionally, preliminary medium-duty orders (Classes 5-7) climbed 37% year-over-year to 20,000 units, ACT said.
“Demand for new equipment remains strong, supported by meaningfully improved freight rates,” Carter Vieth, ACT research analyst, said in a news release. “While largely driven by severe contractions in the driver supply earlier this year, the Montgomery SCOTUS decision, stricter ELD/HOS rule enforcement, and new carrier registration rules have also added to supply constraints and rate improvement through 2026.”
Vieth also observed that carrier financials are improving, adding, “Q2 earnings from the publicly traded group of TL carriers highlight the fleets’ profitability recovery, with aggregate net profit margins hitting a nearly-three-year high in Q2.”
Pre-buy concludes as industry eyes 2027
FTR reported Class 8 net orders at 18,200 units for August, marking a 19% drop from July but a 42% increase compared to August of the previous year.
The firm stated that over the past 12 months, orders have totaled 350,677 units, with the 2026 order season tracking 39% higher than the prior-year period. FTR also said most surcharge-free model year 2026 engine build slots are now likely filled, indicating the EPA 2027 NOx pre-buy is essentially complete.
“The main issue now is incremental cost,” said Dan Moyer, FTR senior analyst for commercial vehicles. “OEM strategies are diverging as some have decided to offer both EPA 2027-compliant engines and current-technology engines with NCPs while at least one manufacturer plans to offer only a fully compliant option.”
Moyer summarized the current market transition by saying, “Overall, August marks the close of the 2026 order season and the effective end of the EPA 2027 NOx pre-buy. September begins a new phase with MY 2027 ordering opening and fleet decisions increasingly shaped by engine choice, pricing, build timing, and the yet-to-be-finalized EPA 2027 NOx compliance framework.”
