Jan 29 (Reuters) - Tesla fell short of

analysts' estimates for gross profit margin in the fourth

quarter on Wednesday, as the electric-vehicle maker rolled out

financing offers and discounts to spur flagging demand for its

aging lineup.

The company's gross profit margin stood at 16.3% in the

October-December period, lower than estimates of 19.03%,

according to 20 analysts polled by LSEG. Tesla posted a profit

margin of 19.8% in the third quarter.
