Star Group Q3: 17% Revenue Growth, but 9.4% Volume Slide Fails the Smell Test

Star's revenue growth obscured a weaker core delivery business

Read this quarter through volume, not revenue. Star's total revenue rose 17.2% to $358.1 million, which looks strong on the surface. But the underlying demand signal was weaker: home heating oil and propane volume fell 9.4% to 32.8 million gallons. For a Main Street energy distributor, that is the more important signal. Revenue can rise with prices; gallons sold show whether the delivery business is holding up.

Revenue rose, but it was still a cost-flow story

Bulls will note that revenue growth came from higher average selling prices. Bears will note that those higher prices mostly reflected higher wholesale product costs. That is an important distinction. If customers are paying more mainly because input costs are higher, the business is moving product through a pricier pipe rather than showing stronger demand, pricing power, or tighter supply.

There were mitigating factors. This was a non-heating period, and softer volume in the shoulder months of April and May weighed on results. Still, Star said net customer attrition contributed to the decline, so the quarter was not only a temperature story.

The takeaway is simple: revenue grew, but the core engine looked weaker. A 17% revenue increase means much less when it came alongside a 9.4% drop in gallons sold and higher wholesale costs.

Insurance costs and derivatives drove the weaker earnings outcome

The softer demand backdrop helps explain the quarter, but the earnings damage was more mechanical than mysterious.

Star's net loss rose by $28.0 million, primarily due to operating pressure and mark-to-market volatility. Operating expenses rose $8.7 million, including $6.2 million in higher insurance costs. At the same time, Star recorded an unfavorable change in the fair value of derivative instruments of $8.6 million. One pressure point reflects a costlier business to run; the other reflects earnings volatility tied to hedging.

Insurance was the clearest operating drag

The $6.2 million insurance hit matters because it points to a real operating cost pressure rather than a pricing quirk. Management tied it to adverse developments in specific claims. When overhead rises while core volume slips, earnings do not improve on their own.

That also helps explain why Adjusted EBITDA loss widened by $7.1 million to $17.7 million, even with some positives in the service business.

Derivatives explain part of the miss, but not all of it

Bulls will argue that part of the derivative result belongs in context, not in the base-business readthrough. That is fair. Weather hedges can work against earnings when conditions differ from expectations.

Still, the $8.6 million quarterly derivative hit is large enough that investors should not dismiss it as routine hedge noise. It likely explains part of the earnings pressure, but not the whole quarter.

Service and installation is the operating line worth watching

There was at least one constructive signal: service and installation gross profit rose $1.4 million. That matters because it reflects existing customers buying more value-added work, not just more gallons moving through the system. Management also said it is expanding HVAC offerings in select markets to reach customers beyond the traditional heating oil and propane base.

The operating questions from here are straightforward:

• Do insurance and other overhead pressures stabilize?
• Does service and installation continue to add profit, not just revenue?
• Does the HVAC push begin to show meaningful traction?

If those answers improve, this quarter may be remembered as a bad mix of weather, insurance, and mark-to-market noise. If not, the market will get less forgiving of the operating slippage.

The next quarter will matter more than the revenue headline

What would confirm the bear case

If Star keeps growing revenue from higher average selling prices while the core delivery business keeps weakening, the market's skepticism will remain reasonable. Another quarter of lower home heating oil and propane volume, combined with renewed customer attrition, would suggest the revenue growth is still not coming from a healthier base business.

What would improve the outlook

The more constructive path starts this fall, because higher market prices are expected to influence customer behavior regarding price-protected plans, with a likely decision point for consumers in October. If Star's next results show volume holding up through that shopping period, investors will have a better reason to trust the business again.

The key test is simple: price-led revenue growth with soft volume and customer attrition keeps the bear case alive. A steadier demand picture, calmer operating costs, and service growth that adds real profit are what would support a more optimistic view.
