Ford Motor ave a fourth-quarter earnings forecast on Wednesday that was below analysts' expectations, sending shares down more than 2 percent in premarket trading.

The No. 2 U.S. automaker said it could see improvement in 2019 earnings and revenue as global industry sales remained flat, but did not provide any figures.

"For 2019, we see the potential for year-over-year improvement in company revenue, EBIT and adjusted operating cash flow," Chief Financial Officer Bob Shanks said in a statement.

He added that the company expected to fully fund its business needs in the coming year "while maintaining cash and liquidity levels at or above our target levels."

Still, Ford saw headwinds for the year ahead, citing tariffs and high commodity costs, both of which also impacted its 2018 earnings. The details on the outlook were contained in slides just ahead of a presentation by Ford early on Wednesday at a Deutsche Bank conference in conjunction with the 2019 North American International Auto Show in Detroit.

Helping the company will be new product rollouts, including the Ford Ranger pickup truck and Explorer sport utility vehicle, its restructuring initiatives, a recovery in China, and the redesign of its money-losing European operations.

Last week, Ford's larger U.S. rival, General Motors Co said it expected higher profits in 2019, offering an estimated range that was far stronger than Wall Street analysts had forecast.

RBC Capital Markets analyst Joseph Spak said the fact that Ford did not provide a formal earnings range for 2019 may be interpreted negatively as the company having less visibility.

"In our minds, the lack of a formal range is likely to lead to more dispersion of estimates and expectations, making it more challenging to 'hit' investor expectations," he said in a research note. "That could add difficulty to Ford's effort to build market confidence in their turnaround plan."

Ford said it expects 2018 adjusted earnings of $1.30 a share on revenue of $160.3 billion. In October, the Detroit area automaker said it expected to earn in the range of $1.30 to $1.50 per share while analysts were expecting $1.33 per share, Refinitiv IBES data showed.

For the fourth quarter, Ford expects adjusted earnings of 30 cents a share, below the 32 cents analysts were expecting.

On Tuesday, Ford and Germany's Volkswagen AG said they would join forces on commercial vans and pickups and were exploring joint development of electric and self-driving technology in a bid to save the automakers billions of dollars.

Shares of Ford fell 2.4 percent to $8.62 in premarket trading.
