TSLA shares could face pressure after first-quarter deliveries fell short of expectations, while Rivian (RIVN) may see a modest boost from its beat, according to a note from Stifel.
The firm said Tesla delivered 358,023 vehicles in the first three months of 2026, missing the consensus forecast by about 2%. Energy storage deployments came in at 8.8 gigawatt-hours, well below the 14.4 GWh that analysts had expected.
Rivian, by contrast, reported deliveries of 10,365 vehicles, exceeding Stifel’s estimate by roughly 4%. The company also reaffirmed its full-year delivery guidance of 62,000 to 67,000 units.
Stifel views Tesla’s results as likely negative for the stock, while Rivian’s performance appears modestly positive. The firm also noted that if gasoline prices remain elevated during and possibly after the Iran conflict, that could support higher EV sales.
Tesla’s storage miss may draw particular attention from investors, as the energy business has been a growing part of the company’s strategy. Rivian’s ability to hold its annual outlook despite a competitive market could be seen as a stabilizing signal.
