Tesla issued $13.8 million in stock to pay for trucks and trailers to transport its electric vehicles from the factory floor to customers, according to a new securities filing.

Instead of cash, the electric car maker used 49,967 shares at a maximum price of $277.05 a share as of Feb. 12 to buy the trailers from Central Valley Auto Transport, a California company that specializes in car carriers, Tesla said Monday in a filing with the Securities and Exchange Commission.

Central Valley Auto Transport hung up the phone during two attempts by CNBC to get comment. An email to the CEO wasn't immediately returned outside of normal business hours. Tesla declined to comment on the filing.
