Ford Motor lost $2 billion during the first quarter and warned investors that losses during the second quarter will widen as the company grapples with the fallout from the coronavirus pandemic that's shuttered factories and devastated sales.

Before taxes, and after adjusting for one-time items, Ford lost $632 million, and that number is expected to top $5 billion during the second quarter, the automaker said Tuesday.

Ford shares were down about 6% during extended-hours trading Tuesday to $5.10, erasing the automaker's gains for the day. Shares of the automaker are down about 42% this year.

The automaker's total revenue, which includes auto sales and financing, slid 14.9% to $34.3 billion. The coronavirus had a "negative effect" of at least $2 billion on the company's earnings during the first three months of the year, Ford said.

The outbreak significantly hobbled Ford's performance, "as protecting people and helping society respond to the crisis became primary measures of current success alongside balance-sheet management and operational excellence," the company said.
