April 26 (Reuters) - Refiner Phillips 66 missed

quarterly profit estimates on Friday, hurt by a slump in

refining margins following a decline in fuel prices.

The Houston-based company reported adjusted earnings of

$1.90 per share for the three months ended March 31, compared

with analysts' estimates of $2.17 per share, according to LSEG

data.
