Star Group, L.P. Reports Fiscal 2026 Third Quarter Results

STAMFORD, Conn., Aug. 05, 2026 (GLOBE NEWSWIRE) -- Star Group, L.P. (the "Company" or "Star") (NYSE:SGU), a home energy distributor and services provider, today filed its quarterly report on Form 10-Q with the SEC and announced financial results for the fiscal 2026 third quarter, the three months ended June 30, 2026.

Three Months Ended June 30, 2026 Compared to the Three Months Ended June 30, 2025 For the fiscal 2026 third quarter, Star reported a 17.2 percent increase in total revenue to $358.1 million compared with $305.6 million in the prior-year period, reflecting an increase in average selling prices, driven by higher wholesale product cost. The amount of home heating oil and propane sold during the fiscal 2026 third quarter declined by 3.4 million gallons, or 9.4 percent, to 32.8 million gallons, as the additional volume provided from acquisitions and colder temperatures was more than offset by the impact of net customer attrition and other factors. Temperatures in Star's geographic areas of operation for the three months ended June 30, 2026 were 15.9 percent colder than the three months ended June 30, 2025 but 5.9 percent warmer than normal, as reported by the National Oceanic and Atmospheric Administration.

Star’s net loss rose by $11.4 million in the quarter, to $28.0 million, primarily due to an unfavorable change in the fair value of derivative instruments of $8.6 million and a $7.1 million increase in Adjusted EBITDA loss, partially offset by a $3.4 million increase in the Company’s income tax benefit and a $0.9 million decrease in depreciation and amortization expenses.

The Company reported a third quarter Adjusted EBITDA loss (a non-GAAP measure defined below) of $17.7 million, up $7.1 million year-over-year, as higher home heating oil and propane per gallon margins, an improvement in service and installation profitability and the additional gross profit from other petroleum products were more than offset by higher operating expenses, including $6.2 million in higher insurance-related expenses, and the lower volume of home heating oil and propane sold.

“Our results this quarter, a non-heating period, largely reflected seasonal factors and net attrition, which was in line with prior-year periods” said Jeff Woosnam, Star Group’s President and Chief Executive Officer. “While temperatures were moderately colder than last year, the volume of home heating oil and propane sold was lower given the more muted impact of additional degree days in the shoulder months of April and May. We did not complete any acquisitions this quarter but are actively assessing a number of possible attractive opportunities. We are taking steps this summer, as in years past, to improve our operations, streamline where appropriate, and prepare for the coming winter months. At the same time, we continue to invest in our service and installation business – where we see further room for growth – and believe Star remains in great shape for the quarters to come.”

Nine Months Ended June 30, 2026 Compared to the Nine Months Ended June 30, 2025 For the nine months ended June 30, 2026, Star reported an 8.3 percent increase in total revenue to $1.7 billion, reflecting higher product volumes sold and an increase in selling prices in response to higher wholesale product costs. The volume of home heating oil and propane sold during the first nine months of fiscal 2026 increased by 8.6 million gallons, or 3.3 percent, to 271.2 million gallons, reflecting colder temperatures and the additional volume provided from acquisitions, more than offsetting net customer attrition and other factors. Temperatures in Star’s geographic areas of operation fiscal year-to-date were 11.5 percent colder than during the prior-year period and 2.9 percent colder than normal, as reported by the National Oceanic and Atmospheric Administration.

For the nine months ended June 30, 2026, Star’s net income increased $13.9 million, to $116.1 million, compared to the prior-year period, primarily due to a $19.9 million increase in Adjusted EBITDA, a favorable change in the fair value of derivative instruments of $1.4 million, and a $0.6 million decrease in depreciation and amortization expenses, partially offset by a $7.6 million increase in income taxes and $0.4 million higher net interest expense.

Year-to-date Adjusted EBITDA increased $19.9 million, to $189.3 million, compared to the nine months ended June 30, 2025, primarily due to an increase in home heating oil and propane per gallon margins and volume sold in the base business, and an increase in Adjusted EBITDA from acquisitions, which more than offset higher operating expenses, of which $1.9 million was attributable to the Company's weather hedge contracts due to colder weather. The temperatures experienced during the weather hedge period ending March 31, 2026 were colder than in th

Star Group, L.P. Reports Fiscal 2026 Second Quarter Results

STAMFORD, Conn., May 06, 2026 (GLOBE NEWSWIRE) -- Star Group, L.P. (the "Company" or "Star") (NYSE:SGU), a home energy distributor and services provider, today filed its quarterly report on Form 10-Q with the SEC and announced financial results for the fiscal 2026 second quarter, the three months ended March 31, 2026.

Three Months Ended March 31, 2026 Compared to the Three Months Ended March 31, 2025 For the fiscal 2026 second quarter, Star reported a 3.2 percent increase in total revenue to $766.7 million compared with $743.0 million in the prior-year period, reflecting higher heating oil and propane volumes sold. The amount of home heating oil and propane sold during the fiscal 2026 second quarter rose by 0.6 million gallons, or 0.4 percent, to 144.5 million gallons, as the additional volume provided from acquisitions and colder temperatures, more than offset the impact of net customer attrition and other factors. Temperatures in Star's geographic areas of operation for the three months ended March 31, 2026 were 6.4 percent colder than the three months ended March 31, 2025 and 2.8 percent colder than normal, as reported by the National Oceanic and Atmospheric Administration.

Star’s net income rose by $22.4 million in the quarter, to $108.3 million, primarily due to a favorable change in the fair value of derivative instruments of $20.7 million, a $10.5 million increase in Adjusted EBITDA, a $0.6 million decrease in depreciation and amortization expense, and $0.4 million lower net interest expense, partially offset by a $9.7 million increase in income tax expense.

The Company reported second quarter Adjusted EBITDA (a non-GAAP measure defined below) of $138.7 million, up $10.5 million year-over-year, primarily due to a $5.3 million increase in Adjusted EBITDA in the base business, $2.1 million higher Adjusted EBITDA from recent acquisitions, and a $3.1 million decrease in expense related to the Company's weather hedge contracts. The increase in Adjusted EBITDA in the base business was driven by the higher home heating oil and propane volume, due to colder weather, an increase in home heating oil and propane per gallon margins, and higher installation profitability, partially offset by an increase in operating expenses. While home heating oil and propane volume grew by just 0.4 percent during this period, the extreme weather conditions significantly impacted direct operating costs, which rose by $4.0 million, or 5.9 percent; insurance expense also increased by $4.0 million largely due to higher claims expense attributable to the weather. At the same time, the Company did not recognize any expense or benefit under its weather hedge contracts in the second quarter of fiscal 2026 (versus a $3.1 million expense recorded for the three months ended March 31, 2025) due to the fact that Star already recognized the cap of $5.0 million expense under its weather hedge contracts during the first quarter.

“The second quarter was, in many ways, a continuation of conditions experienced in the first. Colder temperatures were the norm across much of our operating footprint, resulting in slightly higher heating oil and propane volumes sold, but the severe weather – including storms and high snowfall – also raised operating expenses,” said Jeff Woosnam, Star Group’s President and Chief Executive Officer. “That said, we were still able to post Adjusted EBITDA of nearly $139 million and kept net customer attrition under 1 percent -- both important accomplishments for the Company. We also closed on one small heating oil acquisition during the quarter. Given the challenges of this past winter, we’re very pleased with how the team performed and are working on continued improvement to our underlying operations in the second half.”

Six Months Ended March 31, 2026 Compared to the Six Months Ended March 31, 2025 For the six months ended March 31, 2026, Star reported a 6.1 percent increase in total revenue to $1.3 billion, reflecting higher product volumes sold and an increase in selling prices in response to higher wholesale product costs. The volume of home heating oil and propane sold during the first six months of fiscal 2026 increased by 12.1 million gallons, or 5.3 percent, to 238.4 million gallons, reflecting colder temperatures and the additional volume provided from acquisitions, more than offsetting net customer attrition and other factors. Temperatures in Star’s geographic areas of operation fiscal year-to-date were 11.0 percent colder than during the prior-year period and 4.1 percent colder than normal, as reported by the National Oceanic and Atmospheric Administration.

For the six months ended March 31, 2026, Star’s net income increased $25.3 million, to $144.1 million, compared to the prior-year period, primarily due to a $27.0 million increase in Adjusted EBITDA and a favorable change in the
