AltaGas Reports Strong Fourth Quarter and Full Year 2025 Results

Mar 06 2026 11:00 GMT

Continued Execution Delivers 2025 Normalized EBITDA at High End of Guidance Range

CALGARY, AB , March 6, 2026 /CNW/ - AltaGas Ltd. ("AltaGas" or the "Company") (TSX: ALA) reported fourth quarter and full year 2025 results, reaffirmed 2026 guidance, and provided an update on its operations, projects and other corporate developments.

Fourth Quarter and 2025 Highlights

(all financial figures are unaudited and in Canadian dollars unless otherwise noted)

Financial Results

Normalized EBITDA¹ was $564 million in the fourth quarter and $1,863 million for the full year of 2025, while income before income taxes was $310 million in the fourth quarter and $1,029 million for the full year of 2025. 2025 normalized EBITDA increased five percent year-over-year and was at the upper-end of AltaGas' guidance range. Midstream growth was driven by strong liquified petroleum gas ("LPG") export volumes and margins. Stronger Utilities performance came from higher rate base, asset optimization and favorable weather.
Normalized EPS¹ was $0.77 in the fourth quarter and $2.23 for the full year of 2025 while GAAP EPS²was $0.67 in the fourth quarter and $2.48 for the full year of 2025. Full year normalized EPS was above the mid-point of AltaGas' guidance range, driven by strong performance across the enterprise, partially offset by higher depreciation and amortization and increased tax expense.

(2) GAAP EPS is equivalent to Net income applicable to common shares divided by shares outstanding.

Operational and Business Highlights

AltaGas exported 124,593 Bbl/d of LPG to Asia in the fourth quarter, with 21 Very Large Gas Carriers ("VLGCs") loaded across the Ridley Island Propane Export Terminal ("RIPET") and the Ferndale Terminal ("Ferndale"). Full‑year exports were a record 126,572 Bbl/d, up four percent year‑over‑year, with 83 ships delivered to Asia.
Midstream throughput increased in 2025, with fourth quarter fractionation and liquids handling volumes up seven percent year‑over‑year, led by the Montney. North Pine throughput reached record volumes and operated near its 25,000 Bbl/d capacity.
Utilities delivered its best safety results on record, with total recordable injury frequency ("TRIF") down meaningfully from historical levels. This improvement reflects strong operational discipline and places SEMCO in the top quartile for safety performance amongst the peer group.

Growth Project Updates

Pipestone II was placed in service in December 2025 and is operating at over 90 percent utilization under long‑term take‑or‑pay contracts.
The Ridley Island Energy Export Facility ("REEF") remains on budget and on schedule for 2026 completion as over 85 percent of capital has been committed or incurred and more than 70 percent of equipment has been delivered and installed. REEF Optimization I construction is underway and will add an additional 30,000 Bbl/d of propane export capacity in the second half of 2027.
Dimsdale Phase I and II expansions will add 6 Bcf of storage capacity by 2026 year-end and another 30 Bcf by mid-2027. The expansions are backed by long-term take-or-pay storage contracts. The facility will help balance LNG demand draws associated with Western Canada's growing production and natural gas exports.
AltaGas' decision to retain its ownership interest in the Mountain Valley Pipeline ("MVP") was further reinforced by strong operational performance and improving outlooks for the MVP Boost and MVP Southgate expansion projects. Recent milestones include unanimous approval of the revised route by the U.S. Federal Energy Regulatory Commission ("FERC") and issuance of key North Carolina water permits for MVP Southgate.
Construction of the 30-mile Keweenaw Connector Pipeline is advancing, with long lead‑time materials procured and all land rights secured. Construction is expected to begin in the second quarter of 2026, with an anticipated in‑service date of early 2027.
AltaGas' Utilities continue to advance data center development opportunities, with engineering and design studies completed in Virginia, Michigan, and Maryland. In late 2025, the Company executed an agreement for the first phase of a 24‑MW data center in Maryland, with Phase I expected to be completed by year‑end 2026.

Regulatory Highlights

In November 2025, the Public Service Commission of the District of Columbia ("PSC of D.C.") approved a US$33 million rate base increase, including a US$12 million roll‑in from the PROJECTpipes 2 Accelerated Replacement Program ("ARP"). Rates became effective January 2026 with an allowed return on equity ("ROE") of 9.65 percent.
Washington Gas filed a US$82 million rate case in Maryland, requesting an ROE of 10.85 percent. Excluding the US$15 million STRIDE modernization program transfer, the net rate increase requested totals US$67 million.
The Virginia State Corporation Commission ("SCC of VA") approved Washington Gas' full US$700 million amendment to the Virginia Steps to Advance Virginia Energy ("SAVE") ARP, extending the program through the end of 2028.
Washington Gas received authorization from the PSC of D.C. to extend the PROJECTpipes 2 modernization program through June 30, 2026, with an additional US$25 million. On March 4, 2026, the PSC of D.C. approved the District Strategic Accelerated Facility Enhancement ("SAFE") modernization program with US$150 million of authorized spending from July 1, 2026 to June 30, 2029.
On February 26, 2026, SEMCO filed a US$61 million rate case in Michigan requesting a 10.75 percent ROE. Proposed rates include capital investments since January 2020 and the pre-approved capital associated with construction of the Keweenaw Connector Pipeline. SEMCO proposed approval of a weather normalization adjustment mechanism and anticipates new rates to be in place by early 2027.

Board Chair Appointment

As part of a planned transition, Derek Evans has been appointed as the incoming Board Chair, effective May 1, 2026. Pentti Karkkainen will continue to serve as Chair until the transition date and will remain on the Board as an active Director thereafter to support continuity and ongoing Board leadership.

2026 Guidance and Financial Updates

AltaGas has had a strong start to 2026 and is reiterating the Company's 2026 full year guidance, including normalized EBITDA of $1.925 billion to $2.025 billion and normalized net income per share of $2.20 to $2.45.
AltaGas' adjusted net debt to normalized EBITDA¹ exited 2025 at 4.7x on a trailing twelve-month basis, including 50 percent debt treatment for its subordinated hybrid notes and preferred shares. This is in line with the Company's targeted leverage range of 4.5 - 5.0x and compares to 5.1x at 2024 year-end.
On December 1, 2025, AltaGas' Board of Directors approved a six percent increase to its 2026 common share dividends to $1.34 per common share annually ($0.334 per common share quarterly). AltaGas also extended its five to seven percent dividend compounded annual growth rate ("CAGR") guidance to 2030.

CEO Message

"2025 was a year of strong execution and disciplined delivery for AltaGas," said Vern Yu, President and Chief Executive Officer of AltaGas. "We achieved the top end of our EBITDA guidance range and delivered earnings per share in the upper half of guidance, reflecting strong performance across our Utilities and Midstream businesses.

"We made meaningful progress against our strategic priorities, where we maximized returns from our existing asset base by achieving record global export volumes, increasing midstream asset utilization, advancing rate cases across multiple jurisdictions, and continuing to drive strong cost management across the organization.

"We further de‑risked the business by securing more than 100,000 barrels per day under long-term contracts for our export business and increasing take-or‑pay commitments at our Dimsdale storage facility. We strengthened our balance sheet and achieved our target credit metrics. The removal of negative outlooks by Fitch and S&P reflects the resilience and durability of our cash flows.

"We executed on our growth projects by bringing Pipestone II into service on-time and on-budget, and we significantly advanced REEF, while adding more than $400 million of new modernization capital in our Utilities business. We were pleased to reach key final investment decisions on our RIPET methanol removal project, REEF Optimization I, and Dimsdale Phase I and II. We also progressed critical infrastructure expansions, including accelerated pipeline replacement project approvals and extensions in Virginia, and the MVP expansion projects.

"Through 2025, we maintained disciplined capital allocation, as demonstrated by our fourth quarter equity issuance and MVP retention, a 6 percent dividend increase for 2026, and meaningful debt reduction, while positioning AltaGas to continue investing in a slate of strong, risk-adjusted returning organic growth opportunities in 2026. These actions underscore the strength of our strategy, the quality of our assets, and our continued focus on long‑term value creation for shareholders."

Business Performance

Utilities

The Utilities segment reported normalized EBITDA of $383 million in the fourth quarter of 2025 compared to $336 million in the fourth quarter of 2024, while income before income taxes was $301 million in the fourth quarter of 2025 compared to $186 million in the fourth quarter in 2024. Fourth quarter 2025 delivered 14 percent year‑over‑year normalized EBITDA growth, driven primarily by continued investment through its modernization programs, the positive impact of asset optimization activities, the partial settlement of Washington Gas' post‑retirement benefit pension plan and favorable weather within its weather exposed jurisdictions. These factors were partially offset by lower contributions from the Retail business and higher operating and maintenance ("O&M") costs, mainly driven by higher employee incentive expenses due to AltaGas' rising share price.

Washington Gas has an active rate case before the PSC of MD, requesting rates designed to generate approximately US$67 million of incremental annual revenue, net of a US$15 million ARP surcharge. New rates are expected to take effect by the fourth quarter of 2026. In Virginia, Washington Gas currently has interim rates in place related to its August 2025 filing, which seeks approximately US$65 million of incremental annual revenue, net of the US$39 million SAVE surcharge, with a final decision anticipated in the second half of 2026.

On February 26, 2026, SEMCO filed a new rate case with the Michigan Public Service Commission ("MPSC") requesting an additional US$61 million of revenue at a requested ROE of 10.75 percent. Requested rates include impacts of inflation and account for capital investments made since January 2020. Proposed rates also capture the pre-approved capital associated with construction of the Keweenaw Connector Pipeline, which is expected to be in service by early 2027. SEMCO proposed approval of a weather normalization adjustment mechanism and anticipates new rates to be in place by early 2027.

The Company continues to de‑risk long‑term revenue through the establishment of pre‑approved system modernization programs that enhance network safety and reliability. Washington Gas received approval for an amendment to the Virginia SAVE modernization program, enabling approximately US$700 million of investment between 2026 and 2028. The approved amendment includes replacement of additional vintage pipe and the deployment of advanced leak‑detection technologies to further improve long‑term safety and reliability. The Company also received approval to extend PROJECTpipes 2 from December 31, 2025 to June 30, 2026, with incremental modernization spending of US$25 million. On March 4, 2026 the Company received approval for the District SAFE modernization program with US$150 million of authorized spending from July 1, 2026 to June 30, 2029. The continuation of the program ensures further modernization spending to increase safety and reliability of the system.

Beyond system betterment and modernization, AltaGas expects to further grow rate base through larger strategic investments, including the Keweenaw Connector Pipeline project in Michigan. Construction of the 30‑mile pipeline is scheduled to commence in the second quarter of 2026, with an estimated capital cost of approximately US$135 million and an anticipated in‑service date of early 2027.

The Company continues to advance several data center development opportunities and has executed an agreement to provide infrastructure supporting the first phase of a 24‑MW data center in Maryland, with Phase I expected to be completed by year‑end 2026. In addition, AltaGas recently completed five data center engineering and design studies across Virginia, Michigan, and Maryland. Data center investment will continue to be pursued on a de‑risked basis, utilizing accelerated rate structures and rate‑regulated investments to support long‑term growth.

During the fourth quarter of 2025, AltaGas invested $255 million across its Utilities business, allocating $115 million to asset modernization programs and $111 million to system betterment. These targeted investments are focused on improving system safety and reliability, while ensuring customers have access to the essential energy needed for daily life.

Midstream

The Midstream segment reported normalized EBITDA of $202 million in the fourth quarter of 2025, compared to $182 million in the fourth quarter of 2024, while income before taxes was $162 million in the fourth quarter of 2025 compared to $181 million in the fourth quarter of 2024. The 11 percent year‑over‑year increase in fourth‑quarter normalized EBITDA was driven primarily by higher export volumes and margins and strong performance at Pipestone I. These results were partially offset by lower margins at Harmattan, higher tolled export volumes, and increased G&A costs, including higher incentive compensation due to AltaGas' rising stock price.

The Midstream business continued to benefit from strong operational execution, delivering record annual export volumes and achieving multiple months of five‑ship loadings per month at RIPET. During 2025, the Company successfully completed three major facility turnarounds, taking place at RIPET, facilities within Northeastern B.C. ("NEBC"), and Pipestone I, all of which were executed on time and on budget with minimal impact to throughput volumes. Across the Midstream value chain, AltaGas achieved record quarterly fractionation volumes at North Pine and record processing volumes at Harmattan and Pipestone I.

AltaGas exported 124,593 Bbl/d of LPGs to Asia in the fourth quarter of 2025, which was spread across 21 VLGCs, including 14 VLGCs at RIPET and approximately seven VLGCs at Ferndale. Global LPG export volumes for the full year of 2025 averaged 126,572 Bbls/d across 83 ships, representing a 4 percent year-over-year volume increase. This growth was complemented by continued diversification of the customer base, with 45 percent of total export volumes shipped to China, increasing AltaGas' market share to approximately six percent of total Chinese propane imports for the year.

AltaGas also delivered strong execution across its Midstream growth project portfolio in 2025. Pipestone II entered service on budget and on schedule, while REEF Phase I advanced through key construction milestones, remains on budget and positioned for mechanical completion by year‑end 2026. Positive final investment decisions for REEF Optimization I and the Dimsdale I and II expansion projects further strengthen the Company's competitive position and expand its backlog of high‑return, capital‑efficient growth opportunities.

AltaGas' realized frac spread averaged $19.85/Bbl, after transportation costs, as most of AltaGas' frac exposed volumes were hedged at approximately $37.27/Bbl in the fourth quarter of 2025, prior to transportation costs. AltaGas is well hedged for 2026 with approximately 68 percent of expected frac exposed volumes hedged at approximately US$21.06/Bbl, prior to transportation costs.

In addition, approximately 80 percent of AltaGas' 2026 expected global export volumes are either tolled or financially hedged with an average Far East Index ("FEI") to North American financial hedge price of approximately US$19.13/Bbl for non-tolled propane and butane volumes. AltaGas continues to actively manage commodity exposure through contracting and hedging and will provide updates on its hedging activities on a quarterly basis.

Corporate/Other

The Corporate/Other segment reported a normalized EBITDA loss for the fourth quarter of 2025 of $21 million, compared to a gain of $2 million in the same quarter of 2024. The decrease was due to lower contributions from Blythe where the facility continues to face congestion issues on the California Independent System Operator ("CAISO") transmission grid, impacting the ability to benefit from merchant energy generation. The segment also faced increased G&A costs related to higher employee incentive expenses due to AltaGas' rising stock price. Loss before income taxes in the Corporate/Other segment was $153 million in the fourth quarter of 2025, compared to $136 million in the same quarter of 2024.

Normalized EBITDA for the fourth quarter of 2025 was $564 million, compared to $520 million for the same quarter of 2024. The largest factors contributing to the year-over-year increase are described in the Business Performance sections above.

Normalized net income was $236 million or $0.77 per share for the fourth quarter of 2025, compared to $227 million or $0.76 per share reported for the same quarter of 2024. The increase was mainly due to the same previously referenced factors impacting normalized EBITDA, lower interest expense, and favourable variances in foreign exchange losses after foreign exchange related normalizations, partially offset by higher normalized income tax expense and higher depreciation and amortization expense. Please refer to the Non-GAAP Financial Measures section of the Press Release and MD&A for further details on normalization adjustments.

Income before income taxes was $310 million for the fourth quarter of 2025 compared to $231 million for the same quarter of 2024. The increase was mainly due to the same previously referenced factors impacting normalized EBITDA, lower transition and restructuring costs, unrealized gains on risk management contracts compared to unrealized losses on risk management contracts in the same quarter of 2024, lower provisions on assets, and lower interest expense, partially offset by higher depreciation and amortization expense, foreign exchange losses compared to foreign exchange gains in the same quarter of 2024, and higher transaction costs related to acquisitions and dispositions.

Net income applicable to common shares was $205 million or $0.67 per share for the fourth quarter of 2025, compared to $203 million or $0.68 per share for the same quarter of 2024.

Normalized funds from operations for the fourth quarter of 2025 was $404 million ($1.32 per share), compared to $397 million ($1.33 per share) for the same quarter of 2024. The increase was mainly due to the same previously referenced factors impacting normalized EBITDA, lower normalized current income tax expense, and lower interest expense, partially offset by higher non-cash items included in normalized EBITDA and foreign exchange losses compared to foreign exchange gains in the same quarter of 2024.

Cash from operations for the fourth quarter of 2025 was $209 million or $0.68 per share, compared to $508 million or $1.70 per share for the same quarter of 2024. Please refer to the three months ended December 31 section of the MD&A for further details on the variance in cash from operations.

Depreciation and amortization expense for the fourth quarter of 2025 was $138 million, compared to $123 million for the same quarter of 2024.

Interest expense for the fourth quarter of 2025 was $120 million, compared to $128 million for the same quarter of 2024. The decrease was mainly due to a decrease in average debt balances, exclusive of hybrid debt, as well as higher capitalized interest, partially offset by interest on taxes and the issuance of additional subordinated hybrid notes in the third quarter of 2025. Interest expense recorded on subordinated hybrid notes for the fourth quarter of 2025 was $37 million, compared to $34 million for the same quarter of 2024.

Income tax expense for the fourth quarter of 2025 was $99 million, compared to $22 million in the same quarter of 2024. The increase was mainly due to higher income before income taxes and tax expense related to legal entity restructuring.

Forward Focus, Guidance and Funding

AltaGas continues to focus on executing its corporate strategy of building a diversified platform that operates long-life energy infrastructure assets that connect customers and markets and are positioned to provide resilient and growing value for the Company's stakeholders.

AltaGas expects to achieve guidance ranges that were previously disclosed in December 2025, including:

2026 Normalized EPS guidance of $2.20 - $2.45 per share, compared to actual normalized EPS of $2.23 and GAAP EPS of $2.48 in 2025; and
2026 Normalized EBITDA guidance of $1.925 billion - $2.025 billion, compared to actual normalized EBITDA of $1.863 billion and income before taxes of $1.029 billion in 2025.

AltaGas is focused on delivering resilient and growing normalized EBITDA and normalized EPS while maintaining financial leverage within its targeted leverage ratio range. This strategy is designed to support steady dividend growth and provide the opportunity for ongoing capital appreciation for long-term shareholders.

AltaGas is maintaining a disciplined 2026 capital program of approximately $1.6 billion, excluding asset retirement obligations ("ARO"). The Company is allocating approximately 69 percent of AltaGas' consolidated 2026 capital to its Utilities business, approximately 27 percent to the Midstream business and the balance to the Corporate/Other segment. The Company will fund the 2026 capital requirements through a combination of internally generated cash flows and an increased debt capacity provided by higher normalized EBITDA.
