NEW YORK (AP) — Tesla's finances rather than its cars were once again in focus Monday following a report that the company asked suppliers for refunds to help it turn a profit.

A memo provided to The Wall Street Journal showed the electric car maker asked one supplier to return what it calls a meaningful amount of money on its payments since 2016. The memo came from a global supply manager and said the request was essential to Tesla's continued operations, the Journal said.

The report also said it's not clear how many suppliers received the request.

When asked whether the company has requested refunds from suppliers, a Tesla spokesman referred to a company statement, which said Tesla had asked fewer than 10 suppliers for a reduction in total spending on projects that started in 2016 and are not complete.

The company said it is also talking to suppliers about changes to future prices and design that will help it reduce costs.

Tesla stock fell 3.3 percent to $303.20 Monday in heavier than normal trading. The stock is down from a peak of $385 in September, with many investors growing concerned about Tesla's spending and its ability to meet its production goals.

Tesla is spending about $1 billion a quarter as it ramps up manufacturing of the Model 3 sedan, a lower-priced car that is key to Tesla's plans of becoming a major mass-market automaker. The 15-year-old company has reported only two quarterly profits in its history and has never made a profit for a full year.

Efraim Levy, a senior equity analyst for CFRA, said he found Tesla's request unusual.

"I haven't heard of this being done before and I've been following the industry for 20 years," he said. "It sounds like something that happens when you're struggling."

Itay Michaeli, an analyst for Citi Investment Research, said automakers sometimes ask for discounts from suppliers, but those are relatively minor matters. He said it's more serious if the company needs more cash to continue operating, noting that investors are likely to be concerned if Tesla has to take unusual steps to shore up its finances.

Tesla had $2.7 billion in cash on hand at the end of the first quarter and many experts think it will need to raise money soon. One way to do that is by selling stock, which could send its share price lower still.

CEO and top shareholder Elon Musk has said that Tesla intends to become profitable in the second half of 2018, and analysts said Monday that the memo is an attempt to meet that goal. But they said if Tesla has to try this hard to meet its target, it might be a self-defeating effort.

"If there are any one-time windfalls that aid in Tesla achieving its profit goals, we expect the market would view that as unsustainable," said Jamie Albertine, senior automotive analyst for Consumer Edge.

In June the company said it was eliminating 3,600 jobs, or 9 percent of its staff, as part of a restructuring effort. At the beginning of July the company said it met a long-time target of building 5,000 Model 3s in a week, but industry analysts have questioned whether Tesla can sustain that pace.
