Shares of self-driving vehicle company Aurora Innovation Inc. plummeted over 15% in pre-market trading on Wednesday after the company reported disappointing third-quarter financial results. Aurora posted a wider-than-expected quarterly loss of $0.13 per share, missing analysts' consensus estimate of a $0.11 loss per share.

The company's disappointing performance highlights its ongoing struggles to control costs and achieve profitability amid fierce competition in the autonomous driving space. The steep stock sell-off underscores investors' concerns over Aurora's path to profitability and its ability to successfully commercialize its self-driving technology.

The company's challenges in meeting profitability expectations have weighed heavily on investor sentiment, raising doubts about its long-term prospects in the highly competitive autonomous driving market.
