Tesla Is Running Out of Excuses for Its Prolonged Sales Slump

Tesla Inc. is expected to report another quarter of weaker sales, and it’s running out of alibis.

Analysts are estimating the carmaker will report on Tuesday that it handed over 441,019 electric vehicles in the second quarter, a 5.4% drop from a year ago. This would be a second consecutive quarterly decline, which Tesla last posted when it was phasing out its first model, the Roadster, in 2012.

Tesla has turned the page on several of the issues that contributed to its struggles early this year, including a suspected arson attack at its factory near Berlin and shipping diversions related to conflict in the Red Sea. That leaves the company with few excuses for its sales slowdown aside from a relatively straightforward problem: Tesla’s older lineup of vehicles is having a harder time keeping up with fresher offerings from rival EV manufacturers.

“It’s tougher to grow when you have increased competition and the current model lineup is a little stale,” said Tom Narayan, a global autos analyst at RBC Capital Markets, who has the equivalent of a buy rating on Tesla’s stock.
