July 22 - U.S. truckmaker PACCAR ( PCAR ) beat

second-quarter profit and revenue estimates on Tuesday, helped

by strong demand in its aftermarket parts segment as more

truckers opted to maintain their existing fleet.

Shares of the Bellevue, Washington-based company rose 5%

in the early hours following the results.

Cautious U.S. truck operators have been deferring new

purchases due to high interest rates and market uncertainty,

fueling demand for aftermarket parts and services.

"The North American truck market is being affected by

economic conditions, the uncertain impact of tariffs and a soft

truckload market," CEO Preston Feight said.

However, this rise in demand for parts and services has

benefitted manufacturers such as PACCAR ( PCAR ), which have been leaning

on aftermarket revenue to counter slower sales of new vehicles.

PACCAR's ( PCAR ) revenue from the parts segment rose 3.4% to $1.72

billion during the second quarter from a year ago.

The company, which designs and manufactures trucks under

brand names Kenworth, Peterbilt and DAF, also relied on

cost-saving measures to combat earlier headwinds from import

duties.

PACCAR ( PCAR ) reported quarterly adjusted profit of $1.37 per

share, surpassing analysts' average estimate of $1.29, according

to data compiled by LSEG.

Its second-quarter revenue of $7.51 billion beat market

expectations of $7.03 billion.
