Tesla shares leaped higher after chief executive Elon Musk said the electric car maker beat Wall Street's revenue expectations, apologized for prior bad manners toward analysts and reiterated a promise for future profitability.

Tesla's stock jumped 9 percent in trading Thursday.

Oppenheimer, which upgraded Tesla shares to outperform following the earnings report, told clients the company may finally be on track with Model 3 production.

"With higher volumes and slower spending, we believe Tesla has reached a critical inflection point in its development," the Oppenheimer analysts wrote. "While we have been cautious on Model 3 ramp, we believe gross margin performance on Model 3 will carry the stock over the next 12 months or more."

Even Goldman Sachs — which has consistently advised clients sell Tesla stock (and continued to do so Thursday) — conceded that the quarter was "solid" for the Palo Alto, California-based company.

"This was a positive quarter. Automotive gross margins, cash burn, and ending cash balance were better than expected. In addition, the company may have turned the corner on its historical operational mis-execution," the Goldman note read. "We see the second quarter as a positive step for Tesla as a manufacturing organization, but a step that requires continued forward momentum in cost control, operating efficiency, and ultimately positive cash flow."
