Star Group (SGU) Q2 2026 earnings review
Weather Drives Earnings Beat, But Organic Volume Stalls
Star Group delivered a highly profitable second quarter, driven by a 6.4% colder YoY weather pattern and earlier exhaustion of its weather hedge caps. Net Income accelerated sharply, rising 26% YoY to $108.3M, aided by a $20.7M favorable swing in derivative instruments. Adjusted EBITDA grew to $138.7M (+8% YoY). However, beneath the strong bottom line, top-line fundamentals show signs of decelerating momentum. Despite significantly colder weather and ongoing M&A contributions, heating oil and propane volume was essentially flat (+0.4%). The business continues to combat underlying customer attrition, and severe winter storms sparked an $8.0M combined surge in operating and insurance expenses.
🐂 Bull Case
Base business Adjusted EBITDA grew by $5.3M. Management successfully capitalized on the colder weather to drive higher per-gallon margins on home heating oil and propane, demonstrating pricing power during peak demand periods.
Because the company absorbed the maximum $5.0M weather hedge expense in Q1, it booked zero expense for Q2 (compared to a $3.1M expense in the prior year). This structurally de-risked Q2 margins.
🐻 Bear Case
After a strong 14.0% YoY volume increase in Q1, Q2 volume growth decelerated sharply to just 0.4%. With weather 6.4% colder than last year, flat volume highlights that net customer attrition is acting as a heavy drag on organic growth.
While cold weather boosts demand, severe storms hurt operations. Direct operating costs rose by $4.0M (5.9%), and insurance claims spiked by an additional $4.0M, eating into gross profit gains.
⚖️ Verdict: ⚪
Neutral. The company successfully translated a cold winter into excellent cash generation and EBITDA growth. However, flat organic volumes in an ideal macro environment (colder weather) suggests that long-term customer attrition is structurally limiting Star's top-line potential without constant M&A.
Key Themes
Contradiction in Installation Segment Profitability
Management's narrative cited 'higher installation profitability' as a driver for the base business. However, reversing the prior year's positive gross margin, GAAP figures for Q2 show Installation and Services generated $76.9M in revenue against $78.4M in costs. This translates to a $1.5M gross loss, down from a $1.7M gross profit in 25Q2. Investors must monitor whether higher branch/overhead costs have permanently impaired this segment's margin profile.
Colder Weather Amplifies Margin
Temperatures were 6.4% colder than prior year and 2.8% colder than normal. While volume grew by barely a fraction, the extreme weather allowed the company to significantly boost per-gallon margins. Colder temperatures force usage, lowering price sensitivity and driving the $5.3M base business EBITDA expansion.
M&A Strategy Keeps Growth Afloat
Acquisitions contributed an incremental $2.1M to Adjusted EBITDA for the quarter ($6.8M year-to-date). With base volume struggling against attrition, Star Group closed another small heating oil acquisition during the quarter, continuing its reliable playbook of buying regional competitors to offset organic churn.
Underlying Customer Attrition
Management noted that customer attrition was 'kept under 1 percent.' While framed positively, the fact that volume only grew 0.4% in a quarter where temperatures were 6.4% colder and inorganic volume was added from acquisitions indicates that this sub-1% attrition is entirely wiping out any organic volume expansion.
Other KPIs
Operating cash flow is reversing. YTD operating cash generation dropped from -$16.0M in 25Q2 to -$61.1M in 26Q2. This was heavily driven by a massive $162.9M build-up in accounts receivable (compared to a $124.7M build last year), tying up working capital as customers defer payments amidst higher winter bills.
The massive acceleration in Net Income (up 26% YoY) was structurally padded by non-cash derivative valuations. Star recorded a $26.8M positive swing in derivative fair value, compared to just $6.1M in the prior year, making the GAAP Net Income look temporarily stronger than core operational cash generation.
Accelerating. Up 3.9% from $124.9M in 25Q2. The harsh weather conditions increased overtime, snow removal, and direct vehicle operating costs. Coupled with a $4.0M spike in weather-related insurance claims, this highlights the double-edged sword of extreme winters for fuel delivery logistics.
Key Questions
Installation Margins Discrepancy
The press release cites 'higher installation profitability', yet the income statement shows cost of installations ($78.4M) exceeded installation sales ($76.9M). Can you reconcile the narrative with the GAAP gross loss?
Receivables Build-up
Accounts receivable increased by nearly $163 million YTD, significantly higher than last year's build. Are you seeing delayed payments or rising bad debt risks as inflation and winter heating costs squeeze consumers?
M&A Pipeline vs Base Erosion
With volume practically flat despite a 6.4% colder winter and recent acquisitions, is the company's M&A pacing sufficient to outrun customer attrition going into the non-heating season?
Insurance Cost Normalization
Insurance expenses spiked by $4.0 million due to severe winter weather claims. Do you expect a portion of these premiums and claim costs to remain structurally elevated in future quarters?
