In its just-released Q4 earnings reports, Tesla again shows a profit, though it's not as high as in Q3. Regardless, a profit is a profit and Tesla has proven to the world that it can indeed make money.

The main financial details from the report are as follows:

Tesla said it earned $139 million, or 78 cents a share, in the quarter, impacted by a $54 million non-cash charge, versus a loss of $4.01 a share in the year-ago quarter.

Adjusted for one-time items, Tesla earned $1.93 a share, versus a $3.04 loss a year ago. Revenue rose to $7.23 billion, compared with $3.29 billion a year ago. 

That profit of 78 cents per share is a solid figure, though the big Q3 profit was way higher at $2.90 per share. However, Q3 was always expected to be a bigger profit quarter for Tesla, so there's no miss here.
