FORTIS INC. RELEASES FIRST QUARTER 2022 RESULTS

AND ANNOUNCES NET-ZERO TARGET

Fortis Inc. ("Fortis" or the "Corporation") (TSX/NYSE: FTS), a well-diversified leader in the North American regulated electric and gas utility industry, released its first quarter results1 and announced a 2050 net-zero target.

Highlights

•First quarter net earnings of $350 million, or $0.74 per common share

•    Adjusted net earnings2 of $0.78 per common share, up from $0.77 in the first quarter of 2021

•Capital expenditures2 of $1.0 billion in the first quarter; $4.0 billion annual capital plan on track

•2050 net-zero direct GHG emissions target announced, building on Fortis' commitment to a clean energy future

•First TCFD and Climate Assessment Report issued during the quarter

•Notice of intent submitted with respect to Tucson Electric Power's next general rate application to be filed in June 2022

"Our first quarter results reflect the stability of our transmission and distribution business," said David Hutchens, President and Chief Executive Officer, Fortis. "With capital investments on track for 2022 and recent progress made on incremental growth opportunities at ITC, we remain confident in our growth outlook."

"We are pleased to take the next step on our ESG journey by committing to a 2050 net-zero direct GHG emissions target, which builds on our mid-term target to reduce GHG emissions 75% by 2035," said Mr. Hutchens. "The net-zero target and TCFD and climate assessment report issued in March align with our focus on operational excellence, sustainable growth and a clean energy future."

Net Earnings

The Corporation reported net earnings attributable to common equity shareholders ("Net Earnings") of $350 million for the first quarter, or $0.74 per common share, compared to $355 million, or $0.76 per common share in the first quarter of 2021. Results for the quarter reflected higher unrealized losses of $14 million on the mark-to-market accounting of natural gas derivatives at Aitken Creek. Excluding this impact, the Corporation delivered earnings growth driven by rate base growth at ITC and the western Canadian utilities, and higher sales in the Caribbean. Growth was partially offset by lower hydroelectric production in Belize, and lower earnings at Central Hudson mainly due to the costs of implementing a new customer information system.

Earnings in Arizona were broadly consistent with the first quarter of 2021. The impact of higher electricity sales and lower planned generation maintenance costs was offset by the timing of earnings related to the Oso Grande wind generating facility, as expected. Losses on retirement investments also unfavourably impacted earnings at UNS Energy in the quarter.

Net earnings per common share also reflected an increase in the weighted average number of common shares outstanding largely associated with the Corporation's dividend reinvestment plan.

Adjusted Net Earnings2

Adjusted net earnings attributable to common equity shareholders ("Adjusted Net Earnings") excludes the impact of mark-to-market accounting of natural gas derivatives at Aitken Creek. Adjusted Net Earnings of $369 million for the first quarter, or $0.78 per common share, were $9 million, or $0.01 per common share higher than the same period in 2021. The increase reflected growth as described for Net Earnings.

Sustainability

In March 2022, the Corporation made significant progress on its commitment as a Task Force for Climate-Related Financial Disclosures ("TCFD") supporter, with the release of its first TCFD and Climate Assessment Report.

Today Fortis further demonstrated its commitment to build a clean energy future by announcing a 2050 net-zero direct greenhouse gas ("GHG") emissions target. With a clear path to achieve the Corporation’s mid-term target of reducing GHG emissions 75% by 2035 compared to 2019 levels without the use of carbon offsets, the Corporation has established this additional target to reinforce its commitment to decarbonize over the long-term, while preserving customer reliability and affordability.

Capital Expenditures

Fortis' $4.0 billion annual capital plan remains on track with approximately $1.0 billion invested during the first quarter.

In April 2022, Woodfibre LNG Limited ("Woodfibre LNG") issued a Notice to Proceed to its prime contractor for the proposed liquefied natural gas site in Squamish, British Columbia. This announcement brings FortisBC’s Eagle Mountain Woodfibre Gas Line project one step closer to construction, though the project remains contingent on Woodfibre LNG making a final investment decision.

During the quarter, progress continued on incremental opportunities not included in the Corporation's $20.0 billion 2022-2026 capital plan. In March 2022, the Province of Ontario issued an Order in Council and Ministerial Directive from the Minister of Energy, instructing the Independent Electricity System Operator ("IESO") to negotiate and, if certain conditions are met, enter into a procurement contract on or before August 15, 2022, for the transmission capabilities of the Lake Erie Connector project. The proposed 1,000 megawatt, bi-directional, high-voltage direct current underwater transmission line will provide the first direct interconnection between the wholesale electricity markets operated by the IESO in Ontario and the PJM Interconnection in the United States.

Also during the quarter, the Midwest Independent System Operator ("MISO”) advanced its long-range transmission plan ("LRTP"), announcing the first tranche of projects across the MISO Midwest subregion comprised of 18 transmission projects with total associated costs estimated at US$10 billion. These projects require MISO board approval which is currently anticipated in July 2022. Six of these projects run through ITC’s MISO operating companies’ service territories, including Michigan and Iowa, where right of first refusal provisions exist for incumbent transmission owners. Other projects within this portfolio may be subject to competitive bidding, depending on the state in which they are located. Based on this preliminary information, ITC estimates transmission investments of US$1 billion to US$1.5 billion through 2030 associated with these projects. Given the preliminary analysis around the transmission investment, at this time Fortis cannot state with certainty the impact of the estimated capital expenditures in connection with the LRTP on the Corporation's five-year capital plan.

Credit Ratings

In March 2022, Standard & Poor's Financial Services confirmed the Corporation's 'A-' issuer and 'BBB+' senior unsecured debt credit ratings and stable outlook.

Regulatory Updates

In March 2022, the Alberta Utilities Commission issued a decision extending the existing allowed rate of return on common equity ("ROE") of 8.5% using a 37% equity component of capital structure through 2023.

In March 2022, the Federal Energy Regulatory Commission approved the settlement agreement for formula transmission rates at Tucson Electric Power ("TEP"), including an ROE of 9.79%.

On May 2, 2022, TEP submitted a notice of intent with the Arizona Corporation Commission to file a general rate application in June 2022. TEP will request that new rates become effective no later than September 1, 2023. TEP's proposed rates will be based on a 2021 test year and will include infrastructure investments made since the last rate case, as well as changes in fuel and non-fuel operating expenses. The filing will also include proposals to eliminate certain adjustor mechanisms, as well as modify an existing adjustor to provide more timely recovery of clean energy investments.

Outlook

The Corporation's long-term outlook remains unchanged. Fortis continues to enhance shareholder value through the execution of its capital plan, the balance and strength of its diversified portfolio of utility businesses, and growth opportunities within and proximate to its service territories. While energy price volatility, global supply chain constraints and rising inflation are issues of potential concern that continue to evolve, including from the effects of the COVID-19 pandemic, war in Eastern Europe, economic sanctions and geopolitical tensions, the Corporation does not currently expect there to be a material impact on operations or financial results in 2022.

Fortis is executing on the transition to a clean energy future and is on track to achieve its corporate-wide target to reduce GHG emissions by 75% by 2035. Upon achieving this target, 99% of the Corporation's assets will be focused on energy delivery and renewable, carbon-free generation. The Corporation's additional 2050 net-zero direct GHG emissions target reinforces Fortis' commitment to decarbonize over the long-term, while preserving customer reliability and affordability.

The Corporation's $20 billion five-year capital plan is expected to increase midyear rate base from $31.1 billion in 2021 to $41.6 billion by 2026, translating into a five-year compound annual growth rate of approximately 6%. Above and beyond the five-year capital plan, Fortis continues to pursue additional energy infrastructure opportunities.

Additional opportunities to expand and extend growth include: further expansion of the electric transmission grid in the United States to facilitate the interconnection of cleaner energy including infrastructure investments associated with MISO's LRTP; natural gas resiliency investments in pipelines and liquefied natural gas infrastructure in British Columbia; the fully permitted, cross-border, Lake Erie Connector electric transmission project in Ontario; and the acceleration of cleaner energy infrastructure investments across our jurisdictions.

Fortis expects long-term growth in rate base will support earnings and dividend growth. Fortis is targeting average annual dividend growth of approximately 6% through 2025. This dividend growth guidance is premised on the assumptions listed under "Forward-Looking Information".
