Tesla posted its first full year of net income in 2020 – but not because of sales to its customers, CNN Business reports.

Eleven US states require automakers sell a certain percentage of zero-emissions vehicles by 2025. If they can't, the automakers have to buy regulatory credits from another automaker that meets those requirements – such as Tesla, which exclusively sells electric cars.
It's a lucrative business for Tesla – bringing in US$3.3 billion over the course of the last five years, nearly half of that in 2020 alone. The US$1.6 billion in regulatory credits it received last year far outweighed Tesla's net income of US$721 million -- meaning Tesla would have otherwise posted a net loss in 2020.
"These guys are losing money selling cars. They're making money selling credits. And the credits are going away," said Gordon Johnson of GLJ Research and one of the biggest bears on Tesla (TSLA) shares.
Tesla top executives concede the company can't count on that source of cash continuing.
"This is always an area that's extremely difficult for us to forecast," said Tesla's Chief Financial Officer Zachary Kirkhorn. "In the long term, regulatory credit sales will not be a material part of the business, and we don't plan the business around that. It's possible that for a handful of additional quarters, it remains strong. It's also possible that it's not."

The 11 states which will require a certain percentage of cars to be zero emission vehicles, or the automakers to purchase credits from a company like Tesla which has exceeded the target, are California, Colorado, Connecticut, Maine, Maryland, Massachusetts, New York, New Jersey, Oregon, Rhode Island and Vermont.
Tesla also reports other measures of profitability, as do many other companies. And by those measures, the profits are great enough that they do not depend on the sales of credits to be in the black.
The company reported 2020 adjusted net income, excluding items such as US$1.7 billion stock-based compensation, of US$2.5 billion. Its automotive gross profit, which compares total revenue from its car business to expenses directly associated with the building the cars, was US$5.4 billion, even excluding the regulatory credits sales revenue. And its free cash flow of US$2.8 billion was up 158% from a year earlier, a dramatic turnaround from 2018 when Tesla was burning through cash and in danger of running out of money.
Its supporters say those measures show Tesla is making money at last after years of losses in most of those measures. That profitability is one of the reasons the stock performed so well for more than a year.
But the debate between skeptics and devotees of the company whether Tesla is truly profitable has become a "Holy War," according to Gene Munster, managing partner of Loup Ventures and a leading tech analyst.
"They're debating two different things. They'll never come to a resolution," he said. Munster believes critics focus too much on how the credits still exceed net income. He contends that automotive gross profit margin, excluding those sales of regulatory credits, is the best barometer for the company's financial success.
"It's a leading indicator," of that measure of Tesla's profit, he said. "There's no chance that GM and VW are making money on that basis on their EVs."
