ALTAGAS REPORTS STRONG FIRST QUARTER 2022 RESULTS

Operating Performance Reflects AltaGas' Continued Focus on Optimizing the Platform, Execution of its Strategic Plan and Drive to Deliver Positive Outcomes for all Stakeholders

CALGARY, AB, April 28, 2022AltaGas Ltd. ("AltaGas" or the "Company") (TSX: ALA) today reported first quarter 2022 financial results and provided an update on the Company's operations.

HIGHLIGHTS

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

• The Midstream segment delivered a strong first quarter of 2022, exporting a first quarter record of 87,967 Bbls/d of liquified petroleum gases (LPGs) to Asia.
  
  
• The Utilities segment continues to focus on delivering clean and affordable energy for its customers, providing reliable and secure energy.
  
  
• The Utilities segment achieved normalized EBITDA growth of approximately 10 percent on a year-over-year basis in the first quarter of 2022, driven by continued investment in the platform. This included Utilities rate base increasing by approximately 10 percent on a year-over-year basis in the first quarter of 2022.
  
  
• Normalized EPS[1] of $1.02 and GAAP EPS2 of $1.27 in the first quarter of 2022 compared to $1.29 and $1.21 in the first quarter of 2021, respectively. First quarter results were reflective of strong operating results across the platform offset by $114 million of lost normalized EBITDA from the U.S. Transportation and Storage business, which had delivered outsized performance in the first quarter of 2021 and was subsequently sold in April 2021.
  
  
• Normalized FFO per share1 of $1.65 and GAAP FFO3 per share of $2.44 in the first quarter of 2022 compared to $2.08 and $2.16 in the first quarter of 2021, respectively. Continued strong cash generation is providing the foundation to fund ongoing operations, organic growth and increase returns of capital to shareholders at a projected five to seven percent compounded annual growth rate through 2026.
  
  
• Normalized EBITDA1 of $574 million and income before income taxes of $504 million in the first quarter of 2022 compared to $674 million and $473 million in the first quarter of 2021, respectively. Results reflect strong execution within Midstream and Utilities operations and leaves AltaGas well-positioned to deliver on its 2022 financial guidance.
  
  
• The Midstream segment reported normalized EBITDA of $174 million and income before income taxes of $159 million in the first quarter of 2022 compared to $304 million and $237 million in the first quarter of 2021, respectively. Operating performance was in line with AltaGas' expectations, reflected increasing Global Exports volumes as the quarter progressed, and the $114 million of lost normalized EBITDA contribution from the U.S. Transportation and Storage business that was divested in April 2021.
  
  
• The Utilities segment reported normalized EBITDA of $408 million and income before income taxes of $426 million in the first quarter of 2022 compared to $371 million and $308 million in the first quarter of 2021, respectively. Results reflected the positive impact of continued investments across the Utilities networks, strong performance from the Retail business and asset optimization during the quarter.
  
  
• Subsequent to the quarter-end, Washington Gas filed an application to increase rates in the District of Columbia (D.C.) by US$53 million. The requested rates include a revenue increase of US$5 million for costs currently collected through the PROJECTpipes surcharge and an incremental revenue request of approximately US$48 million driven primarily by infrastructure investments to continue to provide safe, reliable service to our customers.

CEO MESSAGE

"AltaGas delivered solid results and continued to execute on our strategic plan during the first quarter of 2022, which positions the platform well to achieve the Company's 2022 and longer-term growth plans," said Randy Crawford, President and Chief Executive Officer. "Our diversified business model continues to provide the stable and predictable results that we expect while delivering long-term benefits to all of our stakeholders. We also continued to fulfill our mission of improving quality of life by safely and reliably connecting our customers to affordable sources of energy during the quarter; the importance of which is reiterated in the period of energy scarcity that we are currently living in.

"Our regulated Utilities performed well in the quarter, delivering strong customer service throughout the quarter while delivering the stable and predictable financial results that we expect from the platform, including growing normalized Utilities EBITDA by approximately 10 percent on a year-over-year basis. We continued to make ongoing investments into our network during the quarter that are focused on improving safety and reliability, reducing long-term operating costs, and delivering improved environmental outcomes; all of which drive better outcomes for our customers. This investment strategy is working as our incoming leak rates were down more than 25 percent on a year-over-year basis in the first quarter of 2022 and we have achieved annual operating and maintenance costs reductions of approximately $20 million since 2019. Our large storage position also partially sheltered our customers from some of the extreme winter gas pricing seen during the peak demand season as we seamlessly delivered our customers with the energy they needed.

"Our Midstream business continued to deliver reliable energy to end customers during the quarter through our integrated value chain, while providing AltaGas with strong financial results that were in line with our expectations. During the quarter we increased Global Exports volumes to approximately 88,000 Bbls/d of LPGs to Asia, spread across 14 Very Large Gas Carriers (VLGCs). Our solid first quarter performance, coupled with the upcoming seasonal availability of direct butane supply from the refineries in Washington State, leave AltaGas well-position to achieve the Company's 2022 export target of approximately 97,000 Bbls/d.

"We remain focused on our de-leveraging strategy and maintaining our investment-grade credit rating, which was reaffirmed by Fitch at BBB with a Stable Rating Outlook, subsequent to quarter-end. Our 2022 capital plan of approximately $995 million remains intact as we continue to execute on our Utilities growth while advancing various growth initiatives within our Midstream platform. Given the strong first quarter, we are well-positioned to meet our 2022 guidance ranges, including normalized EPS guidance of $1.80 - $1.95 and normalized EBITDA guidance of $1.50 billion - $1.55 billion."

RESULTS BY SEGMENT

BUSINESS PERFORMANCE

Utilities

The Utilities segment reported normalized EBITDA of $408 million in the first quarter of 2022 compared to $371 million in the first quarter of 2021, while income before taxes was $426 million in the first quarter of 2022 compared to $308 million in the first quarter of 2021. AltaGas continued to upgrade critical infrastructure with the deployment of $128 million of invested capital1 during the first quarter of 2022, including $62 million deployed on the Company's various Accelerated Replacement Programs (ARPs) with a focus on improving the safety and reliability of the system, which also brings long-term operating costs and environmental benefits. This level of capital deployment was in line with scope and budget for the first quarter of 2022 and leaves AltaGas well-positioned to deliver on planned network upgrades with rate base increasing by approximately 10 percent over the same quarter last year.

On April 4, 2022, Washington Gas filed an application to increase rates in D.C. by US$53 million. The requested rates include a revenue increase of US$5 million for costs currently collected through the PROJECTpipes surcharge and an incremental revenue request of approximately US$48 million driven primarily by infrastructure investments to continue to provide safe, reliable service to our customers. Washington Gas has requested that new rates be implemented by February 2023.

The Retail business generated $21 million of normalized EBITDA in the first quarter of 2022 due to higher gas prices, favourable margins and the timing impact of swap gains between the first and second quarters of 2022. The latter has the effect of pulling profits into the first quarter of 2022 rather than the second quarter of 2022 and, as such, AltaGas expects some of these benefits to be reduced in the coming quarters as the year progresses within the Retail business.

Midstream

The Midstream segment reported normalized EBITDA of $174 million in the first quarter of 2022 compared to $304 million in the first quarter of 2021, while income before taxes was $159 million in the first quarter of 2022 compared to $237 million in the first quarter of 2021. Results were reflective of strong operating performance across the platform offset by the $114 million of lost normalized EBITDA contribution from the U.S. Transportation and Storage business, which had outsized performance in the first quarter of 2021 and was subsequently divested in April 2021.

Global Exports contributed $81 million of normalized EBITDA to the Midstream segment in the first quarter of 2022 compared to $70 million in the first quarter of 2021. AltaGas exported a first quarter record of 87,967 Bbls/d of cleaner burning LPGs to Asia, which was spread across 14 VLGCs in the first quarter of 2022 and included an average of 52,766 Bbls/d of propane being exported at RIPET across eight ships and an average of 35,201 Bbls/d of combined butane and propane being exported at Ferndale across six ships. Global Exports volumes were modestly impacted by the carry over effects associated with the extreme weather and flooding experienced on the west coast during the fourth quarter of 2021 that continued into the early part of the first quarter of 2022 with export volumes rising as the first quarter progressed. Export volumes were a record for the first quarter, despite these logistical challenges.

AltaGas' realized frac spread averaged $23.92/Bbl, after transportation costs, with most of AltaGas' frac exposed volumes financially hedged during the quarter. AltaGas is well hedged for 2022 with approximately 77 percent of the remaining 2022 expected frac exposed volumes hedged at approximately $34.58/Bbl, prior to transportation costs. In addition, approximately 41 percent of AltaGas' remaining 2022 expected global export volumes are either tolled or financially hedged with an average FEI to North American financial hedge price of US$10.10/Bbl for non-tolled propane and butane volumes.

Corporate/Other

The Corporate/Other segment reported a normalized EBITDA loss of $8 million in the first quarter of 2022 compared to a $1 million loss in the same quarter of 2021 while income loss before taxes was an $81 million in the first quarter of 2022 compared to a $72 million in the first quarter of 2021. The $7 million year-over-year decrease in normalized EBITDA was driven by the combination of: 1) higher corporate expenses, which were primarily related to employee incentive plans because of AltaGas' strong corporate performance and rising share price; and 2) costs related to a planned spring outage at the Blythe Energy Center in California during the quarter.

CONSOLIDATED FINANCIAL RESULTS

Normalized EBITDA for the first quarter of 2022 was $574 million compared to $674 million for the same quarter in 2021. The largest factors leading to the variance are described in the Business Performance sections above.

Income before income taxes was $504 million for the first quarter of 2022 compared to $473 million for the same quarter in 2021. Net income applicable to common shares was $357 million or $1.27 per share for the first quarter of 2022, compared to $337 million or $1.21 per share for the same quarter in 2021. Please refer to the Three Months Ended Section of the MD&A for further details on the variance in income before income taxes and net income applicable to common shareholders.

Normalized net income was $285 million or $1.02 per share for the first quarter of 2022, compared to normalized net income of $361 million or $1.29 per share reported for the same quarter of 2021. The decrease was mainly due to the same factors impacting normalized EBITDA, including the $114 million of lost normalized EBITDA associated with the larger than expected contribution from the U.S. Transportation and Storage business in the first quarter 2021 that was subsequently sold in April 2021, and higher depreciation and amortization expense, partially offset by lower normalized income tax expense and lower net income applicable to non-controlling interests.

Normalized FFO was $462 million or $1.65 per share for the first quarter of 2022, compared to $583 million or $2.08 per share for the same quarter in 2021. The decrease was mainly due to the same previously referenced factors impacting normalized EBITDA.

Cash from operations in the first quarter of 2022 was $682 million or $2.44 per share, compared to $605 million or $2.16 per share for the same quarter in 2021. Please refer to the Liquidity Section of the MD&A for further details on the variance in cash used by operations.

Depreciation and amortization expense was $112 million for the first quarter of 2022, compared to $99 million for the same quarter in 2021. The increase was mainly due to the absence of depreciation and amortization adjustments made in the first quarter of 2021 related to the Petrogas purchase price allocation and the U.S. Transportation and Storage business, and the impact of new assets placed in-service.

Interest expense for the first quarter of 2022 was $71 million, compared to $70 million for the same quarter in 2021. The slight increase in interest expense was mainly due to higher average debt balances, partially offset by lower average interest rates.

FORWARD FOCUS, GUIDANCE AND FUNDING

Looking ahead, AltaGas continues to be focused on executing its long-term corporate strategy of building a diversified platform that operates long-life energy infrastructure assets that are positioned to provide resilient and durable value for the Company's stakeholders.

AltaGas expects to achieve guidance ranges that were previously disclosed in December 2021, including:

• 2022 Normalized EPS guidance of $1.80 - $1.95, compared to actual normalized EPS of $1.78 and GAAP EPS of $0.82 in 2021.
• 2022 Normalized EBITDA guidance of $1.50 billion - $1.55 billion, compared to actual normalized EBITDA of $1.49 billion and income before taxes of $446 million in 2021.

AltaGas continues to focus on delivering durable and growing EPS and FFO per share while targeting lowering leverage ratios within the business over time. This strategy should support steady dividend growth and provide the opportunity for ongoing capital appreciation for its long-term shareholders. AltaGas has announced forward plans to deliver regular, sustainable and annual dividend increases that compound in the years ahead with an anticipated five to seven percent compounded annual growth rate through 2026. Annual dividend increases will be a function of financial performance and determined by the Board on an annual basis.

AltaGas' 2022 invested capital plan is approximately $995 million, excluding asset retirement obligations, compared to $798 million deployed in 2021. The 2022 invested capital plan is heavily weighted towards the Utilities business and is comprised primarily of ARP and system betterment projects that are anticipated to deliver stable and transparent rate base growth and positive risk-adjusted returns. The Company is allocating approximately 31 percent of AltaGas' consolidated 2022 capital to ARPs in its Utilities business, representing approximately 40 percent of the total 2022 Utilities capital program.
