As construction progresses on Nikola's manufacturing facility in Arizona, its first two batches of trucks were produced at a partner's plant in Germany. Those Tre battery-electric trucks were shipped to the U.S. for testing and commissioning activities. The company said in its first-quarter financial update that it expected technicians in Germany to shift to Arizona by the end of June to begin building battery-electric as well as hydrogen fuel cell electric trucks there. Investors should get a new update during Nikola's second-quarter financial report planned for Aug. 3.
