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.

Refiner margins scaled back from the peaks achieved after

Russia's invasion of Ukraine in 2022, amid a rise in global

refining capacity.

The company said its realized margins fell to $10.91 per

barrel in the first quarter from $20.72 per barrel a year

earlier.

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.
