The Delaware bankruptcy filing sent shares tumbling nearly 60% in pre-market trading.
Lordstown, an electric vehicle startup founded in 2018, went public via SPAC in October 2020 and peaked at $435 per share amid the pandemic EV boom. At one point, Lordstown had a market value of more than $5 billion.
Former President Donald Trump played a role in the stock's rise, as shares soared on the day Trump viewed a 2021 Lordstown Motors 2021 endurance truck.
"We've been working on this very long and very hard," President Trump said on September 28, according to Fox News. "They went in and they have an incredible vehicle."
Shares had precipitously declined as investor focus shifted to profitability. In the most recent quarter, Lordstown posted net sales of $189,000.
Lordstown still has parts that might interest a buyer including a plant in Lordstown, Ohio. Lordstown also recently resumed the production and deliveries of its Endurance pickup truck in April. The company paused those processes in February to address quality issues.
The company noted in a press release that the Endurance is a certified, production-launched vehicle and could "serve as a springboard" for an original equipment manufacturer.
In its lawsuit, Lordstown argued Foxconn didn't fulfill the terms of an agreement that included a stalled $47 million investment.
"As one of the early entrants to the EV industry, we have delivered the Endurance, an innovative and highly-capable EV with significant commercial and retail potential — and had subsequently engaged with Foxconn in a purposeful, strategic partnership to leverage this expertise into a broader EV development platform," Lordstown CEO and President Edward Hightower said in a statement. "Despite our best efforts and earnest commitment to the partnership, Foxconn willfully and repeatedly failed to execute on the agreed-upon strategy, leaving us with Chapter 11 as the only viable option to maximize the value of Lordstown's assets for the benefit of our stakeholders. We will vigorously pursue our litigation claims against Foxconn accordingly."
