NORTH AMERICAN TRUCK MARKET VOLUMES

** Morgan Stanley says fears of a slowdown in CMI's power systems were overdone; notes two months of strong orders suggest the North American Class 8 truck market has bottomed and could recover this year

** Jefferies says CMI's power systems should drive 2026 growth; sees potential for truck volumes to inflect in second half of the year with long-term growth boosted by a secular power-gen cycle

** Truist says the North American truck cycle is early in recovery with better orders and expects CMI to beat and raise guidance through the year
