TuSimple Holdings said Thursday it will cut 30% of its workforce in the United States under a restructuring as the autonomous driving technology company looks to preserve its balance sheet amid a funding crunch in the sector.

The shares of the San Diego-based company fell more than 8% in premarket trading.

TuSimple also said it is no longer seeking strategic alternatives for its Asia Pacific business, backtracking on plans it announced in March last year for the unit.

Industry executives and investors have been worried about the funding poured into the self-driving technology sector at a time when access to capital has been tight.

The restructuring is expected to cost the company between $12 million and $13 million, it said in a statement, adding that the layoffs will only impact its employees in the U.S.

The move comes days after the firm received a delisting notice from Nasdaq for not filing its quarterly report on time.

TuSimple said following restructuring it would continue to retain its level 4 technology development capabilities and focus on autonomous freight transportation technology.

It follows a restructuring the company announced in December and cut about 350 jobs.
