The DTL agreement is a concrete commercial milestone, but the per-mile economics and revenue impact are undisclosed, while the Stoneridge announcement is exploratory, making the move larger than the disclosed fundamentals support.

KDK opened at $1.29, briefly fell to $1.20, then climbed to $1.36 before ending the regular session at $1.30, up 16.5% from the previous close. TapeRank found no filings or headlines within 24 hours to explain the early move, while the later news covered a 75-truck driverless deployment agreement with DTL Transport and a collaboration with Stoneridge; TapeRank tied that catalyst to the move but read the advance as stretched because the deal’s economics were undisclosed and the partnership was exploratory. After the close, the stock reached $1.55, its largest recorded move at 38.4% on the day.
