Murphy USA Inc. (NYSE: MUSA) saw its shares spike 10.04% on Wednesday, closing at $612.16, as investors drew optimism from Casey's General Stores' stronger-than-expected quarterly results, which highlighted robust fuel margins across the convenience store and gas station sector.
The stock hit an intraday high of $614.24, with trading volume surging to 542,124 shares from 289,138 in the prior session. The move came without any company-specific earnings release, instead fueled by peer performance.
Casey's Results Spark Sector Rally
Casey's General Stores (NASDAQ: CASY) rallied 20.29% to close at $915.60 after reporting fiscal fourth-quarter results that exceeded expectations. The company posted a 1.5% increase in same-store fuel gallons and a fuel margin of 46.9 cents per gallon. Fuel gross profit jumped 29.1% to $397.4 million, underscoring the profitability potential in pump operations.
The fuel margin metric, measured in cents per gallon (cpg), is a key indicator for convenience store operators, as it directly impacts earnings. Casey's strong performance served as a catalyst for the sector, with Murphy USA benefiting from the positive sentiment.
Murphy's Own Margin Story
Murphy USA's own first-quarter results, reported in April, already showed similar trends. The company's total fuel contribution reached 35.0 cpg, up from 25.4 cpg in the same period last year. Net income soared to $136.3 million, or $7.28 per diluted share, compared to $53.2 million, or $2.63 per diluted share, a year earlier.
CEO Mindy West noted in April that the refined-product market had behaved favorably, with retail margins holding up and higher prices benefiting the fuel supply business. The first-quarter total fuel contribution dollars rose 40.6% to $403.9 million, while retail fuel volumes edged up 2.1%.
Market Context and Risks
While the sector rally reflects optimism that high margins will persist, fuel prices remain volatile. Murphy's annual filing highlights that gasoline margins fluctuate with refined-product prices, geopolitical events, supply dynamics, competition, and inflation. Rising fuel prices could dampen consumer spending and reduce miles driven, potentially weighing on volumes.
Murphy USA operates approximately 1,800 stores across 27 states, many located near Walmart, catering to value-conscious customers with a low-price, high-volume fuel model. This setup makes the company particularly sensitive to changes in fuel margins.
Investors are now looking ahead to Murphy's second-quarter report. The company guided in its Q1 release that April volumes were roughly flat and fuel margins would remain in the 35-to-40 cpg range. If summer driving trends or wholesale price movements erode those margins, the stock's recent gains may not be sustainable without confirmation from Murphy's own results.
