Craig-Hallum analyst Eric Stine notes that Westport has finalized an HPDI agreement with Weichai in China. The analyst views this as a "very significant event" for Westport as it opens up a "massive growth opportunity" in a market that is by far the largest in the world, LNG for trucking is well-established and accelerating, and LNG fueling infrastructure is well-built out. With the addition of Weichai, Westport has gained further validation of its proprietary HPDI technology and now counts two leading OEMs as customers, he contends. Stine reiterates a Buy rating and $5 price target on the shares.
