Having already postponed its promised North Carolina factory once, the Vietnamese electric carmaker VinFast is reportedly considering an additional delay to a planned $4 billion auto plant in Chatham County. On Wednesday, Reuters cited an unnamed source familiar with the company’s efforts in North Carolina who said the facility may not open until after 2025.

It’s been more than two years since state leaders announced VinFast would build its first foreign plant about 30 miles southwest of Raleigh near the unincorporated town of Moncure. The news was celebrated by officials, as North Carolina had spent several decades trying to attract a major automotive assembly plant. At the time, VinFast said the facility would open in 2024. A year later, the company acknowledged production wouldn’t start until sometime in 2025.

Now, even this timeline appears overly ambitious. Though the carmaker held an official groundbreaking ceremony at the Moncure site last July, no significant vertical construction has yet taken place. In April, The News & Observer reported construction had paused as VinFast revised its site building plans, which Chatham County is currently reviewing.

This is a developing story and will be updated.
