Star Group, L.P. Reports Fiscal 2023 Second Quarter Results

STAMFORD, Conn., May 03, 2023 (GLOBE NEWSWIRE) -- Star Group, L.P. (the "Company" or "Star") (NYSE:SGU), a home energy distributor and services provider, today announced financial results for its fiscal 2023 second quarter ended March 31, 2023.

Three Months Ended March 31, 2023 Compared to the Three Months Ended March 31, 2022
For the fiscal 2023 second quarter, Star reported a 5.7 percent decline in revenue to $737.6 million compared with $782.5 million in the prior-year period, reflecting a decrease in total volume sold, partially offset by the impact of acquisitions and other factors.

The volume of home heating oil and propane sold during the fiscal 2023 second quarter decreased by 27.8 million gallons, or 18.7 percent, to 121.1 million gallons as the additional volume provided from acquisitions and other factors was more than offset by the impact of extremely warm weather and net customer attrition. Temperatures in Star's geographic areas of operation for the fiscal 2023 second quarter were 18.7 percent warmer than during the fiscal 2022 second quarter and 21.6 percent warmer than normal, as reported by the National Oceanic and Atmospheric Administration. The second quarter of fiscal 2023 was also the warmest such period in over 100 years within the New York City metropolitan area.

Star’s net income declined by $19.3 million in the quarter, to $62.0 million, primarily due to an unfavorable change in the fair value of derivative instruments of $20.6 million, a $2.3 million increase in interest expense, and lower Adjusted EBITDA of $5.5 million, partially offset by an $8.6 million decrease in income tax expense.

Second quarter Adjusted EBITDA decreased by $5.5 million, to $102.2 million, compared to the three months ended March 31, 2022, as the decline in home heating oil and propane volume more than offset an increase in per gallon margins and a $14.0 million higher benefit recorded under the Company’s weather hedge program. For the three months ended March 31, 2023, the Company recorded a benefit of $12.9 million under its weather hedge – reflecting warmer temperatures – versus a charge of $1.1 million for the three months ended March 31, 2022.

“As the largest provider of home heating oil in the nation, our business is highly dependent on weather – which negatively impacted us this quarter,” said Jeff Woosnam, Star Group’s President and Chief Executive Officer. “To put this in perspective, not only were temperatures 21.6 percent warmer than normal, but the period was also the warmest in New York City in 123 years; year-to-date, it was the fourth warmest period on record in this key market. While there is nothing we can do to influence mother nature, we are adept at mitigating, to the extent possible, unusual weather swings like this – managing costs and working capital and adjusting short-term investment decisions. At the same time, our weather hedge program has provided an important buffer under such conditions, as has our disciplined approach to controlling operating expenses even in the face of certain inflationary pressures. As we navigate through the remainder of fiscal 2023 I remain confident in our ability to provide the best possible customer experience and bottom line results.”

Six Months Ended March 31, 2023 Compared to the Six Months Ended March 31, 2022
For the six months ended March 31, 2023, Star reported a 9.0 percent increase in total revenue to $1.4 billion compared with $1.3 billion in the prior-year period, reflecting an increase in selling prices in response to higher wholesale product costs, partially offset by a decrease in total volume sold.

The volume of home heating oil and propane sold during the first six months of fiscal 2023 decreased by 25.6 million gallons, or 10.8 percent, to 210.3 million gallons as the additional volume provided from acquisitions was more than offset by warmer temperatures, net customer attrition and other factors. Temperatures in Star’s geographic areas of operation fiscal year-to-date were 6.9 percent warmer than during the prior-year period and 15.7 percent warmer than normal, as reported by the National Oceanic and Atmospheric Administration.

Star’s net income declined by $20.3 million for the first six months of fiscal 2023, to $75.6 million, primarily due to an unfavorable change in the fair value of derivative instruments of $24.9 million, a $4.4 million increase in interest expense, and lower Adjusted EBITDA of $0.9 million, partially offset by an $9.0 million decrease in income tax expense. 

Year-to-date Adjusted EBITDA decreased by $0.9 million, to $151.2 million, compared to the prior-year period as a decline in home heating oil and propane volume more than offset an increase in per gallon margins and an $11.4 million higher benefit recorded under the Company’s weather hedge. As of March 31, 2023, the Company had recorded a benefit of $12.5 million under its weather hedge program versus a benefit of $1.1 million for the first six months of fiscal 2022.

EBITDA and Adjusted EBITDA (Non-GAAP Financial Measures)
EBITDA (Earnings from continuing operations before net interest expense, income taxes, depreciation and amortization) and Adjusted EBITDA (Earnings from continuing operations before net interest expense, income taxes, depreciation and amortization, (increase) decrease in the fair value of derivatives, other income (loss), net, multiemployer pension plan withdrawal charge, gain or loss on debt redemption, goodwill impairment, and other non-cash and non-operating charges) are non-GAAP financial measures that are used as supplemental financial measures by management and external users of the Company’s financial statements, such as investors, commercial banks and research analysts, to assess Star’s position with regard to the following:

• compliance with certain financial covenants included in our debt agreements;
• financial performance without regard to financing methods, capital structure, income taxes or historical cost basis;
• operating performance and return on invested capital compared to those of other companies in the retail distribution of refined petroleum products, without regard to financing methods and capital structure;
• ability to generate cash sufficient to pay interest on our indebtedness and to make distributions to our partners; and
• the viability of acquisitions and capital expenditure projects and the overall rates of return of alternative investment opportunities.
  

The method of calculating Adjusted EBITDA may not be consistent with that of other companies, and EBITDA and Adjusted EBITDA both have limitations as analytical tools and so should not be viewed in isolation but in conjunction with measurements that are computed in accordance with GAAP. Some of the limitations of EBITDA and Adjusted EBITDA are as follows:

• EBITDA and Adjusted EBITDA do not reflect cash used for capital expenditures;
• although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will have to be replaced and EBITDA and Adjusted EBITDA do not reflect the cash requirements for such replacements;
• EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, working capital;
• EBITDA and Adjusted EBITDA do not reflect the cash necessary to make payments of interest or principal on indebtedness; and
• EBITDA and Adjusted EBITDA do not reflect the cash required to pay taxes.
  

REMINDER:
Members of Star's management team will host a webcast and conference call at 11:00 a.m. Eastern Time tomorrow, May 4, 2023. The webcast will be accessible on the company’s website, at www.stargrouplp.com, and the telephone number for the conference call is 888-346-3470 (or 412-317-5169 for international callers).
