NorthWestern Reports First Quarter 2024 Financial Results

BUTTE, Mont. and SIOUX FALLS, S.D., April 25, 2024 (GLOBE NEWSWIRE) — NorthWestern Energy Group, Inc. d/b/a NorthWestern Energy (Nasdaq: NWE) reported financial results for the three months ended March 31, 2024. Net income for the period was $65.1 million, or $1.06 per diluted share, as compared with net income of $62.5 million, or $1.05 per diluted share, for the same period in 2023.

“Solid regulatory execution provided for quarter-over-earnings growth. New rates in Montana and South Dakota helped offset mild weather and a few one-time headwinds in the first quarter,” said Brian Bird, President and CEO. “We are affirming 2024 earnings guidance and remain on track to complete our $500 million capital plan, including the in-service of our 175 megawatt Yellowstone County Generating Station in Montana. Additionally, we expect to release our updated Wildfire Mitigation Plan soon which includes our new Public Safety Power Shutoff process. The plan recognizes and addresses the unique needs of our customers, communities and first responders.”

FIRST QUARTER 2024 COMPARED TO FIRST QUARTER 2023

The increase in net income was primarily due to new base rates resulting from the Montana and South Dakota rate reviews, higher transmission revenues, and higher Montana property tax tracker collection, partly offset by lower electric and natural gas retail volumes, higher non-recoverable Montana electric supply costs, higher depreciation and depletion expense, higher operating, maintenance, and administrative expenses, and higher interest expense. Diluted earnings per share also increased as a result of higher net income but was partially offset by increased average shares outstanding due to equity issuances during 2023.

Adjusted non-GAAP diluted earnings per share for the quarter ended March 31, 2024 was $1.09 as compared to $1.05 for the same period in 2023. See “Adjusted Non-GAAP Earnings” and “Non-GAAP Financial Measures” sections below for more information on these measures.

COMPANY UPDATES

Affirming 2024 Earnings Guidance, Capital Plan and Long-Term EPS Growth

We are affirming 2024 diluted earnings guidance of $3.42 – $3.62 per diluted share and our $500 million capital plan. This guidance is based upon, but not limited to, the following major assumptions:

• Normal weather in our service territories;
• An effective income tax rate of approximately 12%-14%; and
• Diluted average shares outstanding of approximately 61.3 million.

We are also affirming our long-term (5 year) diluted earnings per share growth guidance of 4% to 6% from a 2022 base year of $3.18 diluted earnings per share on a non-GAAP basis. We expect rate base growth of 4% to 6%. Our current capital investment program is sized to provide for no equity issuances. Future generation capacity additions or other strategic opportunities may require equity financing.

Dividend Declared

NorthWestern Energy Group’s Board of Directors declared a quarterly common stock dividend of $0.65 per share payable June 28, 2024 to common shareholders of record as of June 14, 2024. Over the longer-term, we expect to maintain a dividend payout ratio within a targeted 60-70% range.

SIGNIFICANT TRENDS AND REGULATION

Refer to the NorthWestern Energy Group Annual Report on the Form 10-K for the year ended December 31, 2023 for disclosure of the significant trends and regulations that could have a significant impact on our business. These significant trends and regulations have not changed materially since such disclosure, except as follows:

Yellowstone County 175 MW plant

Construction of the new generation facility continues to progress and we expect the plant to be operational by the end of the third quarter 2024. The lawsuit challenging the Yellowstone County Generating Station air quality permit, which required us to suspend construction activities for a period of time, as well as additional related legal and construction challenges, delayed the project timing and have increased costs. As of March 31, 2024, total costs of approximately $267.5 million have been incurred, with expected total costs of approximately $310.0 million to $320.0 million.

Montana Rate Review

We anticipate filing a Montana electric and natural gas rate review with the Montana Public Service Commission (MPSC) in the third quarter of 2024 based on a 2023 test year. Within this rate review filing we also anticipate a prudence review of the Yellowstone County Generating Station.

Power Costs and Credits Adjustment Mechanism (PCCAM)

As of March 31, 2024, we have under-collected our total Montana electric supply costs for the July 2023 through June 2024 PCCAM year by approximately $24.0 million. The significant increase to our under-collected costs during the three months ended March 31, 2024 was driven by a January cold weather event in our service territory. We also remained under-collected for the July 2022 through June 2023 PCCAM year by approximately $8.5 million, which we expect to recover within rates by June 2024. We submit quarterly and annual PCCAM filings with the MPSC to recover, or refund, under- or over-collected Montana electric supply costs. PCCAM rates are being adjusted through the quarterly filings to provide a more timely recovery of deferred balances instead of annual recovery.

Under the PCCAM, net costs higher or lower than the PCCAM Base (excluding qualifying facility costs) are allocated 90 percent to Montana customers and 10 percent to shareholders. For the three months ended March 31, 2024, we under-collected supply costs of $27.1 million resulting in an increase in our under-collection of costs, and recorded a decrease in pre-tax earnings of $3.0 million (10 percent of the PCCAM Base cost variance). For the three months ended March 31, 2023, we over-collected costs of $4.3 million resulting in a decrease to the under-collection of costs, and recorded an increase in pre-tax earnings of $0.5 million.

Our electric supply from owned and long-term contracted resources is not adequate to meet our peak-demand needs. Because of this, the volatility of market prices for energy on peak-demand days, even if only for a few days in duration, exposes us to potentially significant market purchases that could negatively impact our results of operations and cash flows. The construction of the Yellowstone County Generating Station and acquisition of Avista’s Colstrip Units 3 and 4 interests are expected to reduce our exposure to market purchases.

Environmental Protection Agency (EPA) Rules

Draft GHG emission standards for existing coal-fired facilities and new coal and gas-fired facilities, including enhanced MATS rules, were released by the EPA in the second quarter of 2023. Our review of these draft rules indicated they would require potentially expensive upgrades at Colstrip Units 3 and 4 to comply, with proposed compliance dates that may not be achievable and / or require technology that is unproven, resulting in significant impacts to costs of the facilities. On April 25, 2024, the EPA released final rules related to GHG emission standards for existing coal-fired facilities and new coal and natural gas-fired facilities as well as final rules strengthening the MATS requirements. The final MATS and GHG Rules will require compliance as early as 2028 and 2032, respectively. We are evaluating how the final GHG and MATS Rules may impact our coal-fired generation facilities and operations.

EXPLANATION OF CONSOLIDATED RESULTS

Three Months Ended March 31, 2024 Compared with the Three Months Ended March 31, 2023

Consolidated gross margin for the three months ended March 31, 2024 was $142.5 million as compared with $130.7 million in 2023, an increase of $11.8 million, or 9.0 percent. This increase was primarily due to new base rates resulting from the Montana and South Dakota rate reviews, higher transmission revenues, and higher Montana property tax tracker collections, partly offset by lower electric and natural gas retail volumes, higher non-recoverable Montana electric supply costs, and higher depreciation and depletion expense.

Consolidated utility margin for the three months ended March 31, 2024 was $300.6 million as compared with $289.0 million for the same period in 2023, an increase of $11.6 million, or 4.0 percent.

Primary components of the change in utility margin include the following (in millions):

Lower electric retail volumes were driven by unfavorable weather in Montana and South Dakota impacting residential demand and lower commercial demand, partly offset by customer growth. Lower natural gas retail volumes were driven by unfavorable weather in Montana and South Dakota impacting residential and commercial demand.

Consolidated operating expenses, excluding fuel, purchased supply and direct transmission expense, were $198.5 million for the three months ended March 31, 2024, as compared with $193.0 million for the three months ended March 31, 2023. Primary components of the change include the following (in millions):

We estimate property taxes throughout each year, and update those estimates based on valuation reports received from the Montana Department of Revenue. Under Montana law, we are allowed to track the increases and decreases in the actual level of state and local taxes and fees and adjust our rates to recover the increase or decrease between rate cases less the amount allocated to Federal Energy Regulatory Commission-jurisdictional customers and net of the associated income tax benefit.

Consolidated operating income for the three months ended March 31, 2024 was $102.1 million as compared with $96.0 million in the same period of 2023. This increase was primarily driven by new base rates resulting from the Montana and South Dakota rate reviews, higher transmission revenues, and higher Montana property tax tracker collections, partly offset by lower electric and natural gas retail volumes, higher non-recoverable Montana electric supply costs, higher depreciation and depletion expense, and higher operating, administrative and general expenses.

Consolidated interest expense was $31.0 million for the three months ended March 31, 2024 as compared with $28.0 million for the same period of 2023. This increase was due to higher interest on long term debt partly offset by lower interest on our revolving credit facilities and higher capitalization of Allowance for Funds Used During Construction (AFUDC).

Consolidated other income was $4.3 million for the three months ended March 31, 2024 as compared with $4.7 million for the same period of 2023. This decrease was primarily due to a $2.5 million non-cash impairment of an alternative energy storage equity investment and an increase in the non-service component of pension expense, partly offset by a $2.3 million reversal of a previously expensed Community Renewable Energy Project penalty due to a favorable legal ruling and higher capitalization of AFUDC.

Consolidated income tax expense was $10.3 million for the three months ended March 31, 2024 as compared to an income tax benefit of $10.2 million for the same period of 2023. Our effective tax rate for the three months ended March 31, 2024 was 13.7% as compared with 14.1% for the same period in 2023.

The following table summarizes the differences between our effective tax rate and the federal statutory rate ($ in millions):

We compute income tax expense for each quarter based on the estimated annual effective tax rate for the year, adjusted for certain discrete items. Our effective tax rate typically differs from the federal statutory tax rate primarily due to the regulatory impact of flowing through federal and state tax benefits of repairs deductions, state tax benefit of accelerated tax depreciation deductions (including bonus depreciation when applicable) and production tax credits.

Consolidated net income for the three months ended March 31, 2024 was $65.1 million as compared with $62.5 million for the same period in 2023. This increase was primarily due to new base rates resulting from the Montana and South Dakota rate reviews, higher transmission revenues, and higher Montana property tax tracker collection, partly offset by lower electric and natural gas retail volumes, higher non-recoverable Montana electric supply costs, higher depreciation and depletion expense, higher operating, maintenance, and administrative expenses, and higher interest expense.

LIQUIDITY AND OTHER CONSIDERATIONS

Liquidity and Capital Resources

As of March 31, 2024, our total net liquidity was approximately $418.2 million, including $4.2 million of cash and $414.0 million of revolving credit facility availability with no letters of credit outstanding. This compares to total net liquidity one year ago at March 31, 2023 of $363.7 million.

Earnings Per Share

Basic earnings per share are computed by dividing earnings applicable to common stock by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of common stock equivalent shares that could occur if unvested shares were to vest. Common stock equivalent shares are calculated using the treasury stock method, as applicable. The dilutive effect is computed by dividing earnings applicable to common stock by the weighted average number of common shares outstanding plus the effect of the outstanding unvested restricted stock and performance share awards. Average shares used in computing the basic and diluted earnings per share are as follows:

(1) Performance share awards are included in diluted weighted average number of shares outstanding based upon what would be issued if the end of the most recent reporting period was the end of the term of the award.

As of March 31, 2024, there were 54,182 shares from performance and restricted share awards which were antidilutive and excluded from the earnings per share calculations, compared to 69,853 shares as of March 31, 2023.

Adjusted Non-GAAP Earnings

We reported GAAP earnings of $1.06 per diluted share for the three months-ended March 31, 2024 and $1.05 per diluted share for the same period in 2023. Adjusted Non-GAAP earnings per diluted share for the same periods are $1.09 and $1.05, respectively. A reconciliation of items factored into our Adjusted Non-GAAP diluted earnings are summarized below. The amount below represents a non-GAAP measure that may provide users of this data with additional meaningful information regarding the impact of certain items on our expected earnings. More information on this measure can be found in the “Non-GAAP Financial Measures” section below.

Non-GAAP Financial Measures

This press release includes financial information prepared in accordance with GAAP, as well as other financial measures, such as Utility Margin, Adjusted Non-GAAP pretax income, Adjusted Non-GAAP net income and Adjusted Non-GAAP Diluted EPS that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.

We define Utility Margin as Operating Revenues less fuel, purchased supply and direct transmission expense (exclusive of depreciation and depletion) as presented in our Consolidated Statements of Income. This measure differs from the GAAP definition of Gross Margin due to the exclusion of Operating and maintenance, Property and other taxes, and Depreciation and depletion expenses, which are presented separately in our Consolidated Statements of Income. A reconciliation of Utility Margin to Gross Margin, the most directly comparable GAAP measure, is included in the press release above.

Management believes that Utility Margin provides a useful measure for investors and other financial statement users to analyze our financial performance in that it excludes the effect on total revenues caused by volatility in energy costs and associated regulatory mechanisms. This information is intended to enhance an investor’s overall understanding of results. Under our various state regulatory mechanisms, as detailed below, our supply costs are generally collected from customers. In addition, Utility Margin is used by us to determine whether we are collecting the appropriate amount of energy costs from customers to allow for recovery of operating costs, as well as to analyze how changes in loads (due to weather, economic or other conditions), rates and other factors impact our results of operations. Our Utility Margin measure may not be comparable to that of other companies’ presentations or more useful than the GAAP information provided elsewhere in this report.

Management also believes the presentation of Adjusted Non-GAAP pre-tax income, Adjusted Non-GAAP net income and Adjusted Non-GAAP Diluted EPS is more representative of normal earnings than GAAP pre-tax income, net income and EPS due to the exclusion (or inclusion) of certain impacts that are not reflective of ongoing earnings. The presentation of these non-GAAP measures is intended to supplement investors’ understanding of our financial performance and not to replace other GAAP measures as an indicator of actual operating performance. Our measures may not be comparable to other companies’ similarly titled measures.

• the impact of extraordinary external events and natural disasters, such as a wide-spread or global pandemic, geopolitical events, earthquake, flood, drought, lightning, weather, wind, and fire, could have a material effect on our liquidity, results of operations and financial condition;
• acts of terrorism, cybersecurity attacks, data security breaches, or other malicious acts that cause damage to our generation, transmission, or distribution facilities, information technology systems, or result in the release of confidential customer, employee, or company information;
• supply chain constraints, recent high levels of inflation for product, services and labor costs, and their impact on capital expenditures, operating activities, and/or our ability to safely and reliably serve our customers;
• changes in availability of trade credit, creditworthiness of counterparties, usage, commodity prices, fuel supply costs or availability due to higher demand, shortages, weather conditions, transportation problems or other developments, may reduce revenues or may increase operating costs, each of which could adversely affect our liquidity and results of operations;
• unscheduled generation outages or forced reductions in output, maintenance or repairs, which may reduce revenues and increase operating costs or may require additional capital expenditures or other increased operating costs; and
• adverse changes in general economic and competitive conditions in the U.S. financial markets and in our service territories.

Our 2023 Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, reports on Form 8-K and other Securities and Exchange Commission filings discuss some of the important risk factors that may affect our business, results of operations and financial condition.
