The two companies announced their planned merger in August, giving Tevva access to U.S. production and targeting revenue of up to $1.5 billion in 2028, but Mesa, Arizona-based ElectraMeccanica terminated the agreement citing "failures by Tevva to disclose ... material information."

Tevva, which has so far raised about $140 million from investors, said it had provided "full and open access" to ElectraMeccanica and "will be seeking recourse through due legal process."

Tevva said it has "re-engaged with a number of investors and public companies looking for a merger," adding it was "confident that from these various opportunities it will secure both medium- and long-term financing to complete its business plan."

In a statement it also said it had a number of fully electric 7.5 tonne trucks in production to hand over to customers.

After attracting billions from investors just a few years ago, many EV startups have struggled as rising inflation and interest rates have shut off access to funding.

A few have begun bankruptcy proceedings, including Swedish-based electric truck maker Volta Trucks which filed for bankruptcy last week.
