What does Star Group, L.P. do?
Star Group, L.P. is a New York Stock Exchange-listed home-energy distributor and services provider under ticker SGU. Through Petro Holdings and local brands, it delivers heating oil and propane, sells diesel and gasoline, and installs and repairs HVAC equipment. The company operates mainly in the Northeast and Mid-Atlantic. Star describes itself as the nation’s largest retail distributor of home heating oil by sales volume in its latest Form 10-Q.
Why does this business matter?
Star is a last-mile distribution and home-comfort business, not an upstream producer. Route density, purchasing, technicians, customer relationships, and emergency response create its operating value.
How does Star Group make money?
Star earns most revenue by buying refined products wholesale and reselling them to residential and commercial customers. Because wholesale prices move rapidly, the key measure is product gross profit per gallon rather than retail price alone. Installation, service-contract, and billable-call revenue diversify the model, but profitability depends on technician productivity, pricing, and scheduling.
Which revenue stream matters most?
sales mix
| Revenue engine | Pricing logic | Primary margin driver | Strategic role |
|---|---|---|---|
| Heating oil and propane | Per-gallon retail pricing, including variable and price-protected plans | Gross profit per gallon, volume, route efficiency, and supply management | Core cash-generation engine during the heating season |
| Other petroleum products | Delivered diesel, gasoline, and heating oil | Commercial volumes and spread discipline | Adds route and customer diversification |
| Equipment installation | Project-based equipment and labor charges | Labor utilization, equipment cost, job mix, and pricing | Captures replacement-cycle spending and supports retention |
| Maintenance and repair | Annual contracts plus billable calls | Contract pricing, call frequency, technician productivity | Creates recurring contact and extends beyond fuel delivery |
What does Star Group’s latest quarter show?
The fiscal 2026 second quarter ended March 31, 2026 and covered the peak heating season. Sales were $766.7 million, up 3.2%. Heating oil and propane volume increased only 0.4% to 144.5 million gallons, while product gross profit rose 7.4% to $277.4 million. Net income reached $108.3 million and Adjusted EBITDA rose 8.2% to $138.7 million. The official second-quarter release cites base-business improvement, acquisitions, and lower weather-hedge expense.
What drove volume and margin?
Temperatures were 6.4% colder than the prior-year quarter and 2.8% colder than normal. Weather added 9.0 million gallons and acquisitions added 2.2 million, nearly offset by 7.0 million gallons lost to attrition and 3.6 million from other factors. Base-business net attrition was 4.2% for the twelve months ended March 31, 2026.
| Q2 FY2026 metric | Reported result | Q2 FY2025 | Interpretation |
|---|---|---|---|
| Heating oil and propane volume | 144.5M gallons | 143.9M gallons | Cold weather and acquisitions barely exceeded attrition and mix effects. |
| Heating oil and propane gross profit | $266.6M; $1.8446 per gallon | $247.5M; $1.7195 per gallon | Per-gallon margin expansion was more important than volume growth. |
| Installations and services sales | $76.9M | $77.9M | Revenue was slightly lower, but installation profitability improved. |
| Limited-partner earnings per unit | $2.66 | $2.01 | Improved income plus a lower unit count supported per-unit results. |
| Net cash from operations | $(5.9)M | $48.6M | Seasonal receivables and inventory absorbed cash despite strong earnings. |
Seasonality, weather, and working capital define Star’s financial profile
Star’s fiscal year ends September 30 and is highly seasonal. About 30% of heating oil and propane volume is sold in the first fiscal quarter and 50% in the second. Star generally earns income in the December and March quarters and records losses in June and September, so annualizing one winter quarter is misleading.
Why can reported earnings and cash flow diverge?
For the six months ended March 31, 2026, Star earned $144.1 million of net income but used $61.1 million of operating cash. Receivables rose $162.9 million, inventory rose $33.8 million, and customer credit balances fell $57.3 million. Full-cycle cash flow is therefore more useful than first-half cash flow.
How does the weather hedge change the economics?
Star uses weather derivatives to soften warm-winter cash risk. Fiscal 2026 contracts could pay up to $15.0 million in a warm outcome but required up to $5.0 million in a cold outcome; the full $5.0 million was triggered. Fiscal 2027 contracts provide up to $12.5 million with no cold-weather payment obligation.
How strong was fiscal 2025?
Fiscal 2025 is the best full-cycle baseline. Star’s full-year release reported $1.784 billion of sales, 282.6 million heating oil and propane gallons, $73.5 million of net income, $114.5 million of operating income, and $136.4 million of Adjusted EBITDA. Weather was 8.2% colder than fiscal 2024 but 8.3% warmer than normal.
| Fiscal-year metric | FY2025 | FY2024 | What changed |
|---|---|---|---|
| Total sales | $1.784B | $1.766B | Volume and service growth offset lower selling prices. |
| Product sales | $1.438B | $1.449B | Lower wholesale-linked prices masked higher gallons. |
| Installations and services sales | $346.8M | $317.3M | The diversification strategy produced 9.3% growth. |
| Operating income | $114.5M | $61.1M | Better product margin, volume, derivatives, and service economics lifted profit. |
| Net income | $73.5M | $35.2M | The year included a favorable derivative-value change and a real-estate gain. |
| Operating cash flow | $71.0M | $111.0M | Cash conversion weakened despite stronger accounting earnings. |

Which strategic turning points shaped Star Group?
Star’s structure reflects consolidation, portfolio reshaping, recapitalization, and bolt-on acquisitions. That history explains the mature heating-oil franchise, renewed propane expansion, partnership governance, and service diversification.
-
1995The predecessor partnership was formed around an initial public offering, establishing the listed limited-partnership structure that still shapes control and distributions.
-
2001The Meenan acquisition expanded the heating-oil platform and contributed a major local brand and customer base.
-
2004The former propane segment was sold, concentrating the company more heavily on heating oil before propane again became an acquisition priority.
-
2006Kestrel Heat became the general partner through a recapitalization, creating the current governance framework in which unitholders do not elect the general partner’s board.
-
2012The board adopted the continuing unit-repurchase plan, adding per-unit capital allocation to the cash-distribution model.
-
2019Jeffrey Woosnam became president and chief executive officer, leading the current emphasis on retention, service profitability, and acquisition integration.
-
2024Star refinanced with a $210M term loan and a $400M seasonal revolving facility, extending liquidity to September 2029.
-
2025–26Four fiscal 2025 acquisitions cost about $80.5M, followed by one small heating-oil acquisition in fiscal 2026, reinforcing the roll-up strategy.
What is management trying to change now?
Management aims to acquire heating-oil and propane businesses, reduce attrition, and improve service profitability. Acquired accounts can offset organic losses and improve route density, while propane can be less seasonal. The risk is paying heavily merely to replace lost customers.
What gives Star Group a competitive advantage?
Star’s moat is operational: customer density, local brands, delivery infrastructure, purchasing, hedging, credit capacity, and technicians. Smaller dealers may have loyalty, but usually lack Star’s scale, seasonal liquidity, acquisition capacity, and ability to spread technology, insurance, compliance, and marketing costs.
Who are the main competitors?
The market is fragmented. Star competes with local dealers, propane marketers such as AmeriGas and Suburban Propane, HVAC contractors, and alternative heating sources. Natural gas and heat pumps can permanently remove fuel accounts, which is why Star identifies conversions and electrification as attrition factors.
| Competitive force | Star’s position | Pressure point |
|---|---|---|
| Local heating-oil dealers | Scale, procurement, credit, and service breadth | Local relationships can support aggressive price competition. |
| National and regional propane marketers | Growing acquired footprint and cross-selling potential | Propane asset prices can rise when consolidators compete. |
| Independent HVAC contractors | Existing customer access and recurring service relationships | Skilled-labor availability and project execution determine margin. |
| Natural gas and electrification | Service capability can follow some customers beyond oil | Conversions permanently shrink fuel volume and route density. |
How financially strong is Star Group?
At March 31, 2026, Star had $12.2 million of cash, $265.2 million of debt, and $241.8 million of borrowing availability. Debt included $87.4 million of seasonal revolver borrowings and $177.8 million of term-loan carrying value. The revolver expands from $400 million to $475 million during December through April, and Star was covenant-compliant.
How does Star allocate capital?
During the six months ended March 31, 2026, Star spent $7.7 million on capex, repaid $10.5 million of term debt, paid $13.0 million of distributions, and repurchased $5.2 million of units at $11.93 each. It spent about $1.0 million on an acquisition. The quarterly distribution rose to $0.1975, or $0.79 annualized, the fourteenth consecutive annual increase, according to the April 2026 announcement.
| Capital use | Six months ended March 31, 2026 | Investor interpretation |
|---|---|---|
| Capital expenditures | $7.7M | Relatively modest asset intensity, but fleet, plants, software, and propane infrastructure still require reinvestment. |
| Term-loan repayment | $10.5M | Scheduled amortization gradually lowers secured debt. |
| Distributions | $13.0M | Supports the income profile but competes with acquisitions and deleveraging for cash. |
| Unit repurchases | $5.2M | Reduces units outstanding and can improve per-unit economics. |
| Acquisitions | $1.0M | Activity was light after approximately $80.5M spent in fiscal 2025. |
Current availability appears sufficient for an ordinary winter. The harder question is how much debt and acquisition spending are needed to offset attrition while maintaining distributions and repurchases.
Who controls Star Group, and why does governance matter?
Star is a limited partnership with corporate tax treatment, so distributions are treated as taxable dividends. At March 31, 2026, 32.8 million common units represented a 99.0% limited-partner interest and about 0.3 million general-partner units represented 1.0%. Kestrel Heat is the general partner; Kestrel Energy Partners appoints its board. Public unitholders do not elect that board.
| Governance element | Current fact | Why it matters |
|---|---|---|
| Limited-partner interest | 99.0%; 32.8M common units at March 31, 2026 | Public investors hold the economic majority but not conventional board-election rights. |
| General-partner interest | 1.0%; approximately 0.3M units | The general partner controls management and key capital decisions. |
| Board appointment | Kestrel Energy Partners appoints Kestrel Heat’s board | Control is structurally different from one-share, one-vote corporations. |
| Board independence policy | At least three independent directors under governance guidelines | Provides oversight within the general-partner framework. |
| Holders of record | Approximately 176 at November 30, 2025 | Record-holder count understates beneficial ownership held through brokers. |
What decisions are concentrated at the general partner?
The general partner controls acquisitions, capital spending, distributions, and repurchases. This can support continuity but reduces common-unitholder influence. Investors should examine incentives, related-party arrangements, payout priorities, and oversight. Star posts governance documents on its investor-relations site.
What opportunities and risks could change Star Group’s outlook?
The upside case requires better retention, higher gross profit per gallon, profitable service growth, and disciplined acquisitions. The downside is customer erosion combined with warm winters, high acquisition prices, labor pressure, or tighter environmental policy. Star’s quarterly-results archive helps separate structural progress from weather.
Which risks are most material?
| Risk | Financial transmission | What to monitor |
|---|---|---|
| Warm weather | Lower gallons, weaker route utilization, and lower product gross profit | Degree days versus normal, volume bridge, and weather-hedge settlements |
| Customer attrition | Lost volume and lower branch density; acquisitions may be needed to replace accounts | Base-business attrition and gallons lost to attrition |
| Electrification and gas conversion | Permanent reduction in the oil-heated addressable market | Policy changes, conversion rates, and growth in non-oil service contracts |
| Wholesale-price volatility | Working-capital stress, renewal resistance, credit losses, and hedging complexity | NYMEX prices, price-protected renewal acceptance, receivables, and derivative positions |
| Acquisition execution | Goodwill, debt, integration cost, and disappointing retained volume | Acquired EBITDA, customer retention, and leverage after transactions |
| Labor and operations | Higher delivery, branch, and service expenses during peak weather | Technician availability, overtime, union agreements, and service-call performance |
Why does Star Group’s business model matter for valuation?
A DCF that extrapolates the latest winter quarter will misstate Star’s value. A better model uses normalized annual gallons, weather-adjusted customer trends, gross profit per gallon, service gross profit, branch expenses, and acquisition contribution, then models full-year working capital, maintenance capex, debt amortization, distributions, and repurchases.
Which assumptions deserve the most sensitivity analysis?
- Normalized weather: use multi-year degree-day and volume relationships rather than the latest winter alone.
- Organic attrition: separate base-business customer losses from acquisition-added accounts.
- Product margin: test gross profit per gallon under competitive and wholesale-price scenarios.
- Service economics: distinguish service revenue growth from actual gross-profit improvement.
- Acquisition reinvestment: treat purchases needed to replace declining accounts as a recurring use of capital, not automatically as optional growth.
- Capital structure: model seasonal revolver balances, interest rates, scheduled term repayments, and covenant headroom.
Enterprise value to normalized Adjusted EBITDA can help, but weather, derivatives, acquisition timing, leases, and pension obligations require adjustment. Distribution yield alone is incomplete if organic customers decline or acquisition debt rises.
What is the key takeaway from Star Group analysis?
Star is a scaled last-mile energy distributor with local operating advantages and a long record of cash returns. Fiscal 2025 and the first half of fiscal 2026 showed that per-gallon margin, weather, acquisitions, and installation economics can create substantial earnings leverage. Seasonal liquidity is ample and capex is modest relative to revenue.
Durability is less certain. Attrition is material, heating oil faces gas and electrification substitution, and acquisitions may become recurring maintenance capital. Governance also differs from a conventional corporation because Kestrel controls the general partner’s board. The core research metrics are retention, normalized gallons, gross profit per gallon, cash conversion, service profitability, acquisition returns, and leverage.
