Casey's General Stores: A High-Margin Retail Play in a Resilient Convenience Sector

The convenience retail sector has long been a barometer for consumer spending, but 2025 has tested its mettle. Volatile fuel markets, inflationary pressures, and rising operational costs have created a challenging backdrop. Yet, Casey's General Stores (CASY) has emerged as a standout performer, leveraging strategic margin management and fuel volume gains to outpace peers. For investors seeking a high-margin retail play, Casey's offers a compelling case study in operational resilience and sector-specific advantages.

Margin Expansion: A Dual-Engine Strategy

Casey's Q2 and Q3 2025 results underscore its ability to drive profitability through two key levers: inside margin expansion and fuel margin optimization. In Q2, the company reported an inside margin of 41.9%, contributing to a 14.8% year-over-year increase in total inside gross profit to $705.5 millionCasey's Announces First Quarter Results^[1]. By Q3, despite a slight dip to 40.9%, the inside margin remained robust, supported by strong performance in high-margin categories like prepared food and dispensed beveragesCasey's Announces First Quarter Results^[1].

Fuel margins, meanwhile, have been a cornerstone of Casey's strategy. In Q2, the company achieved a fuel margin of 41.0 cents per gallon, translating to a 18.8% year-over-year rise in total fuel gross profit to $373.6 millionCasey's Announces First Quarter Results^[1]. While Q3 saw a marginal decline to 36.4 cents per gallonCasey's Announces First Quarter Results^[1], this still outperformed industry benchmarks.

Fuel Volume Gains: Sustaining Growth Amid Sector Headwinds

Fuel volume growth has been another critical driver. Casey's reported a 1.7% year-over-year increase in same-store fuel gallons in Q2 and a 1.8% rise in Q3Casey's Announces First Quarter Results^[1]. These gains are particularly notable given the broader industry's struggles. In 2024, convenience retail fuel volume grew by just 0.7%, with sales declining due to lower gas prices rather than increased demandConvenience Store News Industry Report 2025: Under Pressure^[3]. Casey's ability to grow fuel volume—while peers stagnate—reflects its strategic focus on customer retention and loyalty programs, which drive repeat visits and incremental sales.

The company's operational efficiencies further amplify these gains. By reducing same-store labor hoursCasey's Announces First Quarter Results^[1], Casey's has offset rising labor costs without compromising service quality. This lean approach, combined with a focus on high-margin merchandise, has allowed it to maintain profitability even as industry-wide fuel margins face downward pressure.

Strategic Expansion: Fueling Long-Term Resilience

Casey's has also prioritized geographic expansion to solidify its market position. Since the start of fiscal 2025, the company has acquired 228 stores and built 21 new locationsCasey's Announces First Quarter Results^[1]. This expansion strategy not only increases its footprint but also diversifies revenue streams, reducing reliance on any single market. In contrast, global peers like Alimentation Couche-Tard (ACT) have faced integration challenges from recent acquisitions, with net earnings dipping to $0.47 per share in Q4 2024Sluggish Start, Strong Finish^[2]. Casey's disciplined approach—focusing on organic growth and strategic acquisitions—positions it to capitalize on regional demand trends.

Industry Context: A Sector Under Pressure, but Casey's Stands Out

Investment Thesis: A High-Margin Play with Structural Advantages

Casey's General Stores exemplifies how strategic execution can turn sector-wide challenges into opportunities. Its dual focus on margin expansion and fuel volume growth has delivered consistent profitability, even as rivals grapple with integration costs and margin erosion. For investors, the company's disciplined cost controls, operational agility, and expansion pipeline make it a rare high-margin play in a sector often characterized by thin margins and cyclical volatility.
