**FILING FORMAT**

This combined Quarterly Report on Form 10-Q is separately filed by Puget Energy, Inc. (Puget Energy) and Puget Sound Energy, Inc. (PSE). Information in this filing relating to PSE is filed by PSE on its own behalf. PSE makes no representation as to information relating to Puget Energy (except as it may relate to PSE) or any other affiliate or subsidiary of Puget Energy. Any references in this report to "the Company" are to Puget Energy and PSE collectively.

------

**FORWARD-LOOKING STATEMENTS**

Puget Energy and PSE include the following cautionary statements in this Form 10-Q to make applicable and to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any forward-looking statements made by or on behalf of Puget Energy or PSE. This report includes forward-looking statements, which are statements of expectations, beliefs, plans, objectives and assumptions of future events or performance. Words or phrases such as "anticipates," "believes," "continues," "could," "estimates," "expects," "future," "intends," "may," "might," "plans," "potential," "predicts," "projects," "should," "will likely result," "will continue" or similar expressions are intended to identify certain of these forward-looking statements and may be included in discussion of, among other things, our anticipated operating or financial performance, business plans and prospects, planned capital expenditures and other future expectations. In particular, these include statements relating to future actions, business plans and prospects, future performance expenses, the outcome of contingencies, such as legal proceedings, government regulation and financial results.

Forward-looking statements reflect current expectations and involve risks and uncertainties that could cause actual results or outcomes to differ materially from those expressed. There can be no assurance that Puget Energy's and PSE's expectations, beliefs or projections will be achieved or accomplished.

In addition to other factors and matters discussed elsewhere in this report, some important risks that could cause actual results or outcomes for Puget Energy and PSE to differ materially from past results and those discussed in the forward-looking statements include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

●  Governmental policies and regulatory actions, including those of the Federal Energy Regulatory Commission and the Washington Commission, that may affect our ability to recover costs and earn a reasonable return, including but not limited to disallowance or delays in the recovery of capital investments and operating costs and discretion over allowed return on investment;

●  Changes in, adoption of and compliance with laws, regulations, executive orders, tariffs, trade restrictions, or other governmental policies or actions, including those relating to federal grant programs, and incentives, funding, budgeting or efficiency measures (including any actual or potential reduction in the federal workforce), national security, environmental protection, climate change, greenhouse gas or other emissions, discharges/releases or by-products of electric generation (including coal ash or other substances) or natural gas distribution and sales, natural resources, and fish and wildlife (including the Endangered Species Act and Migratory Bird Treaty Act) as well as the risk of litigation arising from such matters, whether involving public or private claimants or regulatory investigative or enforcement measures;

●  Changes in tax law, related regulations or differing interpretation, or enforcement of applicable law by the Internal Revenue Service (IRS) or other taxing jurisdiction (including the eligibility and availability of tax credits, and its effects on construction timelines of certain projects); and PSE's ability to recover costs in a timely manner arising from such changes;

●  Inability to realize deferred tax assets and use tax credits due to insufficient future taxable income;

●  Accidents or natural disasters, such as hurricanes, windstorms, earthquakes, floods, landslides, fires and wildfires (either affecting or caused by PSE's facilities or infrastructure), extreme weather conditions and other acts of God, terrorism, asset-based or cyber-based attacks, pandemics or similar significant events can delay projects, interrupt service and lead to lost revenue, cause temporary supply disruptions and/or price spikes in the cost of fuel and raw materials, impose extraordinary costs, and subject the Company to liability;

●  Commodity price risks associated with procuring natural gas and power in wholesale markets from creditworthy counterparties;

●  Wholesale market disruption, which may result in a deterioration of market liquidity, increase the risk of counterparty default, affect the regulatory and legislative process in unpredictable ways, negatively affect wholesale energy prices and/or impede PSE's ability to manage its energy portfolio risks and procure energy supply, affect the availability and access to capital and credit markets and/or impact delivery of energy to PSE from its suppliers;

●  Financial, legal or other difficulties of other energy companies or suppliers and related events, which may affect the regulatory and legislative process in unpredictable ways, adversely affect the availability of and access to capital and credit markets and/or impact delivery of energy to PSE from its suppliers;

●  The effect of wholesale market structures (including, but not limited to, regional market designs or transmission organizations) or other related federal initiatives;

●  PSE electric or natural gas distribution systems failure, blackouts or large curtailments of transmission or distribution systems (whether PSE's or others'), or failure of the interstate natural gas pipeline delivering to PSE's system, all of which can affect PSE's ability to deliver power or natural gas to its customers and generating facilities;

●  Electric plant generation and transmission system outages, which can have an adverse impact on PSE's expenses with respect to repair costs, added costs to replace energy or higher costs associated with dispatching a more expensive generation resource;

●  The ability to restart generation following a regional transmission disruption;

●  The ability of a natural gas or electric plant to operate as intended;

●  PSE's resource adequacy needs to meet the Washington CETA and the Washington CCA requirements, through a combination of owned or contracted resources, may significantly increase purchased power and gas costs if pricing pressures and supply constraints on resource acquisitions increase;

●  Changes in climate, weather conditions, or sustained extreme weather events in PSE's operational territory, which could have effects on customer usage and PSE's revenue and expenses;

●  Regional or national weather conditions (including conditions and events associated with climate change), wildfires, droughts, earthquakes, and other natural disasters, which could impact PSE's ability to procure adequate supplies of natural gas, fuel or purchased power to serve its customers and the cost of procuring such supplies;

●  Variable hydrological and wind conditions, which can impact PSE's ability to generate electricity from hydroelectric facilities and wind facilities, respectively;

●  The ability to renew contracts for electric and natural gas supply and the price and terms of renewal;

●  Industrial, commercial and residential growth and demographic patterns in the service territories of PSE;

●  General economic conditions in the Pacific Northwest, such as inflation, which may impact customer consumption or affect PSE's accounts receivable;

●  The loss of significant customers, changes in the business of significant customers or the condemnation of PSE's facilities as a result of municipalization or other government action or negotiated settlement, which may result in changes in demand for PSE's services;

●  The failure of information systems or the failure to secure information system data, which may impact the operations and cost of PSE's customer service, generation, distribution and transmission;

●  Opposition and social activism that may hinder PSE's ability to perform work or construct infrastructure;

●  Capital market conditions, including changes in the availability of capital and interest rate fluctuations;

●  General economic and political conditions, such as the effects of geopolitical tensions related to the ongoing Russia-Ukraine, Middle East and other international conflicts, recessions, tariffs and trade restrictions, fuel prices, international currency fluctuations, sanctions, corruption, political instability, acts of war and local and national elections;

●  Employee workforce factors including strikes; work stoppages; retirements; absences due to pandemics, accidents, natural disasters or other significant, unforeseeable events; and availability of qualified employees or the loss of a key executive;

●  PSE's ability to attract, retain, and compensate employees while operating within a region of high demand for skilled workers resulting in significant competition and wage pressure;

●  The ability to obtain insurance coverage, the availability of insurance for certain specific losses, including those arising from catastrophic events such as wildfires and the cost of such insurance;

●  Changes in Puget Energy's or PSE's credit ratings, which may have an adverse impact on the availability and cost of capital for Puget Energy or PSE generally and the ability to pay dividends;

●  Deteriorating values of the equity, fixed income and other markets which could significantly impact the value of investments of PSE's retirement plan, post-retirement medical benefit plan trusts and the funding of obligations thereunder; and

●  Recent laws enacted, amended or proposed in Washington and other municipalities in PSE's service territory, which may impact PSE's operations by, among others: changing system planning; changing existing statutory targets; instituting electrification requirements; or establishing Washington Commission requirements.

Any forward-looking statement speaks only as of the date on which such statement is made, and, except as required by law, the Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. For further information, see Part I, Item 1A, "Risk Factors" in the Company's most recent Annual Report on Form 10-K for the year ended December 31, 2025.

COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

**(1)Summary of Significant Accounting Policies**

**Basis of Presentation** 

Puget Energy is an energy services holding company that owns PSE, which is a public utility incorporated in the state of Washington that furnishes electric and natural gas services in a territory covering approximately 6,000 square miles, primarily in the Puget Sound region. Puget Energy also has a wholly owned non-regulated subsidiary, Puget LNG, which has the sole purpose of owning and operating the non-regulated activity of the Tacoma LNG facility. PSE and Puget LNG are considered related parties with similar ownership by Puget Energy. Therefore, capital and operating costs that are incurred by PSE and allocated to Puget LNG are related party transactions by nature.

In 2009, Puget Holdings, owned by a consortium of long-term infrastructure investors, completed its merger with Puget Energy (the merger). As a result of the merger, all of Puget Energy's common stock is indirectly owned by Puget Holdings. The acquisition of Puget Energy was accounted for in accordance with FASB ASC 805, "Business Combinations" (ASC 805), as of the date of the merger. ASC 805 requires the acquirer to recognize and measure identifiable assets acquired and liabilities assumed at fair value as of the merger date.

The consolidated financial statements of Puget Energy reflect the accounts of Puget Energy and its subsidiaries. PSE's consolidated financial statements include the accounts of PSE and its subsidiary. Puget Energy and PSE are collectively referred to herein as "the Company." The consolidated financial statements are presented after elimination of all significant intercompany items and transactions. PSE's consolidated financial statements continue to be accounted for on a historical basis and do not include any ASC 805 purchase accounting adjustments. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

**Allowance for Credit Losses**

The Company measures expected credit losses on trade receivables on a collective basis by receivable type, which includes electric retail receivables, natural gas retail receivables, and electric wholesale receivables. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts.

The following table presents the activity in the allowance for credit losses for accounts receivable for the three months ended March 31, 2026 and 2025:

| Total ending allowance balance | $28870 | $43299 |

*_____________*

<sup>1</sup> *$4.7 million and $9.3 million of provision related to balances of deferred costs specific to COVID-19 as of March 31, 2026 and 2025, respectively.*

**Tacoma LNG Facility**

Operational since February 2022, the Tacoma LNG facility at the Port of Tacoma provides peak-shaving services to PSE's natural gas customers and provides LNG as fuel to transportation customers, particularly in the marine market. In December 2019, the Puget Sound Clean Air Agency (PSCAA) issued the air quality permit for the facility, and the Pollution Hearings Control Board of Washington State upheld the approval following extended litigation.

Based on an order by the Washington Commission, approximately 43.0% of common capital and operating costs are allocated to PSE, the regulated portion of the Tacoma LNG facility. The remaining 57.0% of common capital and operating costs of the Tacoma LNG facility is allocated to Puget LNG, the unregulated portion of the Tacoma LNG facility. Per this

------

allocation of costs, $228.2 million and $228.9 million of net non-utility plant related to Puget LNG's portion of the Tacoma LNG facility is reported in the Puget Energy "Other property and investments" line item as of March 31, 2026 and December 31, 2025, respectively. Additionally, $6.4 million and $7.1 million of operating costs are reported in the Puget Energy "Non-utility expense and other" financial statement line item for the three months ended March 31, 2026, and March 31, 2025, respectively. Further, $222.5 million and $223.2 million of natural gas plant related to PSE's portion of the Tacoma LNG facility is reported in the PSE "Utility plant - Natural gas plant" financial statement line item as of March 31, 2026 and December 31, 2025, respectively, as PSE is a regulated entity.

**Variable Interest Entities**

PSE has certain PPAs in which PSE has variable interests mainly including fixed price contracts for renewable energy. The most significant economic activity for these variable interest entities (VIEs) is typically the operation and maintenance of the facility, which is performed by the seller. Therefore, the Company is not the primary beneficiary of any of these VIEs as it does not control the commercial and operating activities that most significantly impact the economic performance of the entities.

The carrying amount of any assets and liabilities related to these VIEs in the Company's balance sheets represent amounts due from the PPAs. The Company can recover these costs through the PCA mechanism. The Company has no residual interest in the entities and has not provided or guaranteed any debt or equity support, liquidity arrangements, performance guarantees, or other commitments associated with these contracts. The aggregate contracted capacity from these VIE projects were 813.8 MW and 723.8 MW at March 31, 2026 and 2025, respectively. Purchased energy of $25.8 million and $25.0 million was recognized in purchased electricity on the Company's consolidated statements of income for the three months ended March 31, 2026 and 2025, respectively. Additionally, $9.8 million and $14.5 million was included in accounts payable on the Company's balance sheets as of March 31, 2026 and December 31, 2025, respectively.

For further information on the Company's accounting policies, see Part II, Item 8, Note 1, "Summary of Significant Accounting Policies" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**(2) New Accounting Pronouncements**

**Recently Adopted Accounting Guidance**

**Interim Reporting**

In December 2025, the FASB issued ASU No. 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements)". ASU 2025-11 is intended to clarify what disclosures should be provided and clarify when the guidance is applicable. The amendments of ASU 2025-11 should be applied prospectively and are effective for annual and interim periods beginning after December 15, 2027, with early adoption permitted. As of March 31, 2026, the Company's disclosures are consistent with the amendment.

**Measurement of Credit Losses Disclosures**

In July 2025, the FASB issued ASU No. 2025-05, "*Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses for Accounts Receivable and Contract Assets*". ASU 2025-05 provides a practical expedient that allows entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. The amendments of ASU 2025-05 should be applied prospectively and are effective for annual and interim periods beginning after December 15, 2025, with early adoption permitted. As of March 31, 2026, the Company's disclosures are consistent with the amendment.

**Accounting Standards Issued but Not Yet Adopted**

**Government Grants**

In December 2025, the FASB issued ASU No. 2025-10, "Government Grants (Topic 832)". ASU 2025-10 establishes authoritative guidance regarding recognition, measurement and presentation for government grants received by business entities. The amendments of ASU 2025-10 should be applied prospectively and are effective for annual and interim periods beginning after December 15, 2028, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-10 on its consolidated financial statements and related disclosures.

------

**Derivatives and Hedging and Revenue with Contracts with Customers**

In September 2025, the FASB issued ASU No. 2025-07, "*Derivatives and Hedging (Topic 815) and Revenue from Contract with Customers (Topic 606)*". ASU 2025-07 addresses stakeholders concerns about i) the application of derivative accounting to contracts with features based on activities or operations of a party to the contract and ii) the diversity of accounting for share -based non-cash consideration. The amendments of ASU 2025-07 should be applied prospectively and are effective for annual and interim periods beginning after December 15, 2026, with early adoption permitted. The Company has evaluated the impact of adopting ASU 2025-07 and has concluded that this will not have a substantial impact on the Company's consolidated financial statements or related disclosures.

**Intangibles - Goodwill and Other - Internal-Use Software**

In September 2025, the FASB issued ASU No. 2025-06, "*Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)*". ASU 2025-06 modernizes the accounting for software costs that are accounted for under Subtopic 350-40. The amendments of ASU 2025-06 should be applied prospectively and are effective for annual and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-06 on its consolidated financial statements and related disclosures.

**Income Statement Reporting Comprehensive Income Disclosures**

In November 2024, the FASB issued ASU 2024-03, "*Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures*". ASU 2024-03 will require disclosure of specific cost and expense information in the notes to the financial statements. Disclosure shall include inventory purchases, employee compensation, depreciation and intangible asset amortization presented in the face of the income statement for continuing operations. It shall also include certain amounts already disclosed under GAAP in the same disclosure as other disaggregation requirements as well as disclose a qualitative description and the amount of selling expenses. ASU 2024-03 will be effective for the Company in annual periods beginning after December 15, 2026. The amendment contemplates changes in disclosures only and the Company continues to assess the impacts of the amendment.

**Transaction Price Allocated to Remaining Performance Obligations**

In December 2020, Puget LNG entered into a contract with one customer where Puget LNG is selling LNG over a 10-year delivery period which began April 1, 2024. The contract requires the customer to purchase a minimum annual quantity even if the customer does not take delivery. The price of the LNG includes a fixed charge, a fuel charge that includes both a market index and fixed margin component and other variable considerations. The fixed transaction price is allocated to the remaining performance obligations which is determined by the fixed charge components multiplied by the outstanding minimum annual quantity.

The Company expects to recognize revenue over the following time periods:

---

| | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|
| **Puget Energy** | | | | | | | |
| *(Dollars in Thousands)* | 2026 | 2027 | 2028 | 2029 | 2030 | Thereafter | Total |
| Remaining performance obligations | $14591 | $19454 | $19454 | $19454 | $19454 | $63227 | $155634 |

---

The Company has elected the optional exemption in ASC 606, "Revenues from Contracts with Customers", under which the Company does not disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. The primary sources of variability are (a) fluctuations in market index prices of natural gas used to determine aspects of variable pricing and (b) variation in volumes that may be delivered to the customer. Both sources of variability are expected to be resolved at or shortly before delivery of each unit of LNG or natural gas. As each unit of LNG or natural gas represents a separate performance obligation, future volumes are wholly unsatisfied.

**(4) Accounting for Derivative Instruments and Hedging Activities**

PSE employs various energy portfolio optimization strategies but is not in the business of assuming risk for the purpose of realizing speculative trading revenue. The nature of serving regulated electric customers with its portfolio of owned and contracted electric generation resources exposes PSE and its customers to some volumetric and commodity price risks within the sharing mechanism of the Power Cost Adjustment. Therefore, wholesale market transactions and PSE's related hedging strategies are focused on reducing costs and risks where feasible, thus reducing volatility in costs in the portfolio. In order to

------

manage its exposure to the variability in future cash flows for forecasted energy transactions, PSE utilizes a programmatic hedging strategy, which extends out three years. PSE's hedging strategy includes a risk-responsive component for the core natural gas portfolio, which utilizes quantitative risk-based measures with defined objectives to balance both portfolio risk and hedge costs.

PSE's energy risk portfolio management function monitors and manages these risks using analytical models and tools. In order to manage risks effectively, PSE enters into forward physical electric and natural gas purchase and sale agreements, fixed-for-floating swap contracts, and commodity call/put options. Currently, the Company does not apply cash flow hedge accounting and therefore records all mark-to-market gains or losses through earnings.

The Company manages its interest rate risk through the issuance of mostly fixed-rate debt with varied maturities. The Company utilizes internal cash from operations, borrowings under its commercial paper program and its credit facilities to meet short-term funding needs. The Company may enter into swap instruments or other financial hedge instruments to manage the interest rate risk associated with these debts.

The following table presents the volumes, fair values and classification of the Company's derivative instruments recorded on the balance sheets:

<sup>2</sup> *Balance sheet classification: Current and Long-term Unrealized loss on derivative instruments.*

<sup>3</sup> *All fair value adjustments on derivatives have been deferred in accordance with ASC 980, "Regulated Operations." The net derivative asset or liability and offsetting regulatory liability or asset are related to contracts used to economically hedge the cost of electricity and physical gas purchased to serve customers.*

<sup>\*</sup> *Electric portfolio derivatives consist of electric generation fuel of 243.3 million MMBtu and purchased electricity of 28.4 million MWhs at March 31, 2026, and 252.9 million MMBtus and 33.8 million MWhs at December 31, 2025.*

It is the Company's policy to record all derivative transactions on a gross basis at the contract level without offsetting assets or liabilities. The Company generally enters into transactions using the following master agreements: WSPP agreements, which standardize physical power contracts; ISDA agreements, which standardize financial natural gas and electric contracts; and NAESB agreements, which standardize physical natural gas contracts. The Company believes that such agreements reduce credit risk exposure because such agreements provide for the netting and offsetting of monthly payments as well as the right of set-off in the event of counterparty default. The set-off provision can be used as a final settlement of accounts which extinguishes the mutual debts owed between the parties in exchange for a new net amount. For further details regarding the fair value of derivative instruments, see <u>[Note 5](#i6847fb33bd864ee7a054df0113aceaeb_76)</u>, "Fair Value Measurements," in the Combined Notes to Consolidated Financial Statements included in Part I, Item 1 of this report.

The electric and natural gas derivative contracts above will be included in power costs during the period they are delivered and will be included in the applicable recovery mechanism.

_______________

<sup>1</sup> *All derivative contract deals are executed under ISDA, NAESB, and WSPP master agreements with right of set-off.&nbsp;&nbsp;&nbsp;&nbsp;*

The Company is exposed to credit risk primarily through buying and selling electricity and natural gas to serve its customers. Credit risk is the potential loss resulting from a counterparty's non-performance under an agreement. The Company manages credit risk with policies and procedures for, among other things, counterparty credit analysis, exposure measurement, and exposure monitoring and mitigation.

The Company monitors counterparties for significant swings in credit default swap rates, credit rating changes by external rating agencies, ownership changes or financial distress. Where deemed appropriate, the Company may request collateral or other security from its counterparties to mitigate potential credit default losses. Criteria employed in this decision include, among other things, the perceived creditworthiness of the counterparty and the expected credit exposure.

It is possible that volatility in energy commodity prices could cause the Company to have material credit risk exposure with one or more counterparties. If such counterparties fail to perform their obligations under one or more agreements, the Company could suffer a material financial loss. However, as of March 31, 2026, approximately 99.3% of the Company's energy portfolio exposure, is with counterparties that are rated investment grade by rating agencies and 0.7% is either rated below investment grade or not rated by rating agencies. The Company assesses credit risk internally for counterparties that are not rated by the major rating agencies.

The Company computes credit reserves at a master agreement level by counterparty. The Company considers external credit ratings and market factors in the determination of reserves, such as credit default swaps and bond spreads. The Company recognizes that external ratings may not always reflect how a market participant perceives a counterparty's risk of default. The Company uses both default factors published by Standard & Poor's and factors derived through analysis of market risk, which reflect the application of an industry standard recovery rate. The Company selects a default factor by counterparty at an aggregate master agreement level based on a weighted average default tenor for that counterparty's deals. The default tenor is determined by weighting the fair value and contract tenors for all deals for each counterparty to derive an average value. The

------

default factor used is dependent upon whether the counterparty is in a net asset or a net liability position after applying the master agreement levels.

The Company applies the counterparty's default factor to compute credit reserves for counterparties that are in a net asset position. The Company calculates a non-performance risk on its derivative liabilities by using its estimated incremental borrowing rate over the risk-free rate. Credit reserves are netted against the unrealized gain (loss) positions. The majority of the Company's derivative contracts are with financial institutions and other utilities operating within the Western Electricity Coordinating Council. PSE also transacts power futures contracts on the Intercontinental Exchange (ICE), and natural gas contracts on the ICE natural gas exchange (NGX) platform. Execution of contracts on ICE requires the daily posting of margin calls as collateral through a futures and clearing agent. As of March 31, 2026, PSE had cash posted as collateral of $64.5 million related to contracts executed on the ICE platform. As a condition of transacting on the ICE NGX platform as well as participating in the Washington state carbon allowance auctions, PSE maintains a standby letter of credit agreement with TD Bank. As of March 31, 2026, PSE had no cash posted with ICE NGX, and $8.0 million was issued under the standby letter of credit agreement in support of natural gas and carbon allowance purchases. PSE did not trigger any collateral requirements with any of its counterparties nor were any of PSE's counterparties required to post collateral resulting from credit rating downgrades during the three months ended March 31, 2026.

The following table presents the aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a liability position and the amount of additional collateral the Company could be required to post:

**(5) Fair Value Measurements**

ASC 820 established a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy categorizes the inputs into three levels with the highest priority given to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority given to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:

Level 1 - Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Level 1 primarily consists of financial instruments such as exchange-traded derivatives and listed equities. Equity securities that are also classified as cash equivalents are considered Level 1 if there are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. Instruments in this category include non-exchange-traded derivatives such as over-the-counter forwards and options.

Level 3 - Pricing inputs include significant inputs that have little or no observability as of the reporting date. These inputs may be used with internally developed methodologies that result in management's best estimate of fair value.

------

Financial assets and liabilities measured at fair value are classified in their entirety in the appropriate fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy. The Company primarily determines fair value measurements classified as Level 2 or Level 3 using a combination of the income and market valuation approaches. Inputs used to estimate the fair value of forwards, swaps and options include market-price curves, contract terms and prices, credit-risk adjustments, and discount factors. Additionally, for options, the Black-Scholes option valuation model and implied market volatility curves are used. Inputs used to estimate fair value in industry-standard models are categorized as Level 2 inputs as substantially all assumptions and inputs are observable in active markets throughout the full term of the instruments. On a daily basis, the Company obtains quoted forward prices for the electric and natural gas markets from an independent external pricing service.

The Company considers its electric and natural gas contracts as Level 2 derivative instruments as such contracts are commonly traded as over-the-counter forwards with indirectly observable price quotes. However, certain energy derivative instruments with maturity dates falling outside the range of observable price quotes or that are transacted at illiquid delivery locations are classified as Level 3 in the fair value hierarchy. Management's assessment is based on the trading activity in real-time and forward electric and natural gas markets. Each quarter, the Company confirms the validity of pricing-service quoted prices used to value Level 2 commodity contracts with the actual prices of commodity contracts entered into during the most recent quarter. The Company's environmental compliance obligation is categorized in Level 2 of the fair value hierarchy and is measured at fair value using a market approach based on quoted prices from an independent pricing service.

**Assets and Liabilities with Estimated Fair Value**

The carrying values of cash and cash equivalents, restricted cash, and short-term debt as reported on the balance sheet are reasonable estimates of their fair value due to the short-term nature of these instruments and are classified as Level 1 in the fair value hierarchy. Investments in life insurance contracts of $44.9 million and $44.8 million at March 31, 2026 and December 31, 2025, respectively, are included in "Other property and investments" on the balance sheet. These investments are carried at cash surrender values, which represent the amount of cash that could be realized under the contracts.

The fair value of the long-term notes was estimated using the discounted cash flow method with the U.S. Treasury yields and the Company's credit spreads as inputs, interpolating to the maturity date of each issue. The carrying values and estimated fair values were as follows:

Realized gains and losses on energy derivatives for Level 3 recurring items are included in energy costs in the Company's consolidated statements of income under purchased electricity, electric generation fuel or purchased natural gas when settled. Unrealized gains and losses on energy derivatives for Level 3 recurring items are deferred as regulatory assets or liabilities on the Company's consolidated balance sheet.

The Company does not use internally developed models to make adjustments to significant unobservable pricing inputs. The only significant unobservable input into the fair value measurement of the Company's Level 3 assets and liabilities is the forward price for electric and natural gas contracts. The weighted average price is calculated as the total market value divided by the total volume of the Company's Level 3 electric and natural gas commodity contracts, respectively, as of the reporting date.

------

The following table presents the forward price ranges for the Company's Level 3 commodity contracts as of March 31, 2026:

The significant unobservable inputs listed above would have a direct impact on the fair values of the above instruments if they were adjusted. Consequently, significant increases or decreases in the forward prices of electricity or natural gas in isolation would result in a significantly higher or lower fair value for Level 3 assets and liabilities. Generally, interrelationships exist between market prices of natural gas and power. As such, an increase in natural gas pricing would potentially have a similar impact on forward power markets. As of March 31, 2026 and December 31, 2025, a hypothetical 10% increase or decrease in market prices of natural gas and electricity would change the fair value of the Company's derivative portfolio, classified as Level 3 within the fair value hierarchy, by $41.5 million and $48.1 million, respectively.

**(7) Regulation and Rates**

**General Rate Case** 

On February 27, 2026, PSE filed a GRC with the Washington Commission in Docket No. UE-260005 and Docket No. UG-260006. The filing included a three-year MYRP requesting an overall increase in electric and natural gas rates of 15.2% and 14.2% respectively in rate year one (expected to approximate calendar year 2027), 3.7% and 3.2%, respectively in rate year two (expected to approximate calendar year 2028) and 8.7% and 3.6% in rate year three (expected to approximate calendar year 2029). PSE requested a return on equity of 10.8% for all three rate years beginning in 2027 and requested an overall rate of return of 8.1% in rate year one and 8.2% in both rate years two and three.

PSE filed a GRC which includes a two-year MYRP with the Washington Commission on February 15, 2024. On January 15, 2025, the Washington Commission issued an order on PSE's 2024 GRC, in Docket Nos. UE-240004 and UG-240005, that approved a weighted cost of capital of 7.52% in 2025 and 7.64% in 2026, a capital structure of 49.0% in common equity in 2025 and 50.0% in 2026, and a return on equity of 9.8% in 2025 and 9.9% in 2026. On January 28, 2025, the Washington Commission approved PSE's electric and natural gas rates in its compliance filing with an overall net revenue change for electric of $378.2 million or 13.3% in 2025 and $191.0 million or 5.9% in 2026 and an overall net revenue change for natural gas of $110.0 million or 10.6% in 2025 and $20.0 million or 1.8% in 2026, with an effective date of January 29, 2025.

**Liquefied Natural Gas Rate Adjustment**

On April 24, 2024, the Washington Commission issued Final Order 07 in Docket No. UG-230393, which determined that PSE acted prudently in developing and constructing the Tacoma LNG Facility and included two primary outcomes. First, the Washington Commission did not authorize recovery of the portion of the Company's deferred return on its investment in the Tacoma LNG Facility that was recorded between February 1, 2022, the date the facility was placed into service, and January 11, 2023, the date PSE's 2022 GRC rates went into effect. Second, the Washington Commission directed PSE to increase the allocation of distribution pipeline investment to Puget LNG. On May 24, 2024, Public Counsel and the Puyallup Tribe of Indians each filed a petition for judicial review of the Washington Commission's Final Order 07. The petitions were filed in Thurston County Superior Court and were consolidated. The parties agreed to seek direct review of the case by the Washington State Court of Appeals. The case was transferred to Division III of the Court of Appeals in March 2025. Petitioners, Public Counsel and the Puyallup Tribe of Indians filed opening briefs on July 11, 2025. Respondents, PSE and the Washington Commission filed briefs on September 10, 2025. Petitioners' reply briefs were filed on October 10, 2025. A hearing date has not yet been set.

**Colstrip Adjustment Rider**

On September 30, 2024, PSE filed proposed revisions to rates under the Colstrip Adjustment Rider Schedule 141COL with the Washington Commission, seeking to recover actual and forecasted costs for Colstrip Units 3 and 4 for calendar year 2025. The proposed revisions would increase PSE's annual revenues by $4.1 million, or 0.1%. On December 19, 2024, the Washington Commission issued Order 01, requiring PSE to file revised tariff pages, with rates effective January 1, 2025, subject to refund pending final determination. The Washington Commission set the matter for adjudication, with a hearing held on September 3, 2025. On December 19, 2025, the Washington Commission concluded that an adjustment to the provisionally approved rate was necessary, decreasing annual revenues by $6.9 million or 0.2% effective January 1, 2026.

On September 30, 2025, PSE filed proposed revisions to rates under the Colstrip Adjustment Rider Schedule 141COL with the Washington Commission in Docket No. 250733 for Colstrip Units 3 and 4 for calendar year 2026. The proposed revisions would decrease PSE's annual revenues by $82.5 million, or 2.3%, including the $6.9 million mentioned above, due to an expected decrease from the removal of Colstrip plant and reduction of operating costs. The revised tariff filed went into effect on January 1, 2026 by operation of law.

**Climate Commitment Act Deferral**

**Electric**

On May 2, 2025, PSE filed a revision to its electric tariff in Docket No. UE-250321, which proposed the establishment of Schedule 111 for electric to allow PSE to recover the costs associated with its electric compliance obligation. PSE's proposal covered the recovery of its electric compliance costs incurred from January 2023 through December 2025 with a recovery period set for the period of August 1, 2025 through December 2026. On July 24, 2025, the Washington Commission approved the recovery of PSE's estimated 2023 and 2024 compliance costs and a pro-rata portion of the 2025 estimated compliance costs in Schedule 111 for electric. In Docket UE-250901, the Washington Commission approved the recovery of the remaining forecasted 2025 allowance obligation and a true-up to known compliance costs for 2023 and 2024, effective January 1, 2026.

Order 01 within Docket No. UE-250321 also required PSE to file a proposal for recovery of 2026 CCA costs, which was made in that same docket on October 1, 2025. On December 24, 2025, the Washington Commission issued Order 01 in Docket No. UE-250747, which approved the total cost of electric CCA compliance will be recovered through PSE's power cost mechanism. Additionally, to the extent PSE uses no cost allowances granted by the WDOE for compliance, the benefit of this will be passed back to customers through the electric Schedule 111 as approved in Docket No. UE-250901. When combined with the adjustment to Schedule 111, noted above, for the recovery of compliance costs, the annual net rate decrease beginning January 1, 2026, is $259.0 million or 7.2%.

As of March 31, 2026, PSE recorded a regulatory asset of $52.5 million, which represents the expense incurred for the purchase of allowances for the GHG emissions associated with the Company's electric business activities for 2023 through 2025, net of amounts to date collected in customer electric rates for CCA obligation costs. Further, PSE recorded a regulatory asset of $61.2 million, which represents the value of no cost allowances passed back to customers that exceeded PSE's actual usage of no cost allowances in 2026.

**Natural Gas**

The ongoing recovery of allowance costs and pass back of proceeds from the sale of consigned no-cost allowances associated with PSE's natural gas business activities is consistent with the approved accounting petitions in Docket Nos. UG-220975 and UG-230471. As of March 31, 2026, PSE recorded a regulatory liability of $15.1 million, which represents the amounts to date over-collected in customer natural gas rates for CCA obligation costs, net of the expense incurred for the purchase of allowances for GHG emissions associated with the Company's natural gas business activities. Additionally, PSE will continue to consign for auction at least the minimum amount of no-cost emission allowances allocated for natural gas business activities in compliance with the CCA, the proceeds of which will continue to be used for the benefit of natural gas customers, as determined by the Washington Commission. PSE does not record a regulatory liability to defer the proceeds until consigned allowances are sold at auction. As of March 31, 2026, PSE recorded a regulatory liability of $49.0 million, which represents the proceeds received from the sale of consigned allowances sold at auction net of proceeds from the sale of consigned natural gas GHG emission allowances passed back through customer rates or used on approved decarbonization projects.

**Power Cost Adjustment Mechanism**

PSE currently has a PCA mechanism that provides for the deferral of power costs that vary from the "power cost baseline" level of power costs. The "power cost baseline" levels are set, in part, based on normalized assumptions about weather and hydroelectric conditions. Excess power costs or savings are apportioned between PSE and its customers pursuant to the

------

graduated scale set forth in the PCA mechanism and will trigger a surcharge or refund when the cumulative deferral trigger is reached.

The following graduated scale used in the PCA mechanism resulted in the following Company and customer shares:

On April 30, 2026, PSE filed the 2025 PCA compliance report in Docket No. UE-260337. The actual 2025 PCA imbalance including interest was $155.6 million. In the 2024 PCA Compliance Docket No. UE-250318, PSE was allowed to collect on an estimated 2025 imbalance of $97.7 million, which was set in rates from October 1, 2025, to December 31, 2026. PSE has collected $42.0 million and forecasts to collect an additional $56.1 million from April 2026 through December 31, 2026. Accordingly, PSE requested to recover the revised remaining 2025 imbalance of $59.5 million over 12 months starting on January 1, 2027.

PSE filed a tariff requesting an update to the PCA mechanism in 2026 within Docket No. UE-250747, which was filed concurrently with the proposed tariff revision for Schedule 111, in Docket No. UE-250901, discussed above. The former revision requested an increase of $748.4 million or 20.8% and incorporated updated market prices for natural gas and CCA emissions allowances, along with corrected forced outage rates for PSE's natural gas-fired generators. The Washington Commission approved PSE's tariff revisions filed, effective January 1, 2026, subject to condition that these tariff revisions will be subject to review and revision in PSE's next GRC and will not be effective until the conclusion of that case or February 28, 2027, whichever occurs first.

On July 8, 2025, PSE filed a tariff revision in Docket No. UE-250537 requesting that the Washington Commission eliminate the deadband and sharing bands in the PCA mechanism. On February 23, 2026, the Washington Commission dismissed PSE's filing and determined that PSE's request would contradict the power cost review process of the two-year rate plan approved in 2025. On February 27, 2026, PSE integrated its request into its GRC filing in Docket No. UE-260005 for the three-year rate plan beginning in 2027.

**Purchased Gas Adjustment Mechanism**

On October 23, 2025, the Washington Commission approved PSE's request for PGA rates in Docket No. UG-250704, effective November 1, 2025. As part of that filing, PSE requested an annual overall revenue decrease of $55.1 million, where PGA rates, under Schedule 101, decrease annual revenue by $7.9 million and the tracker rates, under Schedule 106, decrease annual revenue by $47.2 million.

**(8) Commitments and Contingencies**

**Legal Matters**

**Washington Climate Commitment Act**

In 2021, the Washington Legislature adopted the CCA, which establishes a GHG emissions cap-and-invest program that requires covered entities, including electric and natural gas utilities, to purchase allowances to cover their GHG emissions with a cap on available allowances beginning on January 1, 2023 that declines annually through 2050.

The WDOE has provided an initial allocation of no-cost allowances to electric utilities, including PSE, for operations through 2026. However, qualifying electric utilities have been allowed to submit revised emissions forecasts approved by the Washington Commission to WDOE. PSE has filed revised forecasts for emissions associated with its 2023, 2025 and 2026 operations, all of which were approved by the Washington Commission. The WDOE approved the revised 2023 forecast and made modest adjustments to the 2026 revised forecast. PSE understands that WDOE will consider changes or adjustments to the 2025 forecast in October 2026, after WDOE has received verified actual emissions for electric operations for calendar year 2025 actual emissions. To the extent WDOE were to determine that an adjustment to the allocation of no-cost allowances for PSE electric operations for calendar year 2025 were appropriate or necessary, PSE understands that such adjustment would occur in the form of an increase or decrease to the allocation of no-cost allowances for PSE electric operations for calendar year 2027.

Given the potential for future rulemakings and the WDOE's ability to adjust no-cost allowances for electric operations during the compliance period or make changes to rules governing the program, there is estimation uncertainty surrounding the Company's ability to estimate its compliance obligation for electric operations both on an annual basis and a four-year compliance period, prior to a final WDOE determination. The WDOE has indicated there will be future rulemakings impacting the compliance obligation, including the true-up mechanism, which could impact periods within the first compliance period; thus, PSE has recorded its compliance obligation based on its best estimate and is unable to determine a range of possible outcomes at this time.

As uncertainties are resolved in future periods, the Company does not anticipate material impacts to its reported earnings due to the cost-recovery mechanisms that exist. For further information, see Part II, Item 8, Note 4, "Regulation and Rates" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Other Commitments and Contingencies**

In addition to the contractual obligations and consolidated commercial commitments disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, during the three months ended March 31, 2026, the Company entered into new Electric Portfolio contracts with estimated payment obligations totaling $94.2 million through 2027. On May 7, 2026, the Company entered into a PPA, which increases the Company's total estimated payment obligation by approximately $165.9 million through 2028.

On July 22, 2025, the Company executed two agreements with the same counterparty that would provide the Company with the output of a 400 MW solar PV energy project and the capacity of a 200 MW battery energy storage system, both over a 25-year term. The total estimated payment obligation during the term of the agreements is approximately $2.1 billion. The

------

agreements contain certain provisions that would allow the counterparty to terminate the agreements before August 31, 2026 for a nominal fee.

For further information regarding the Company's commitments and contingencies, see Part II, Item 8, Note 15, "Commitments and Contingencies" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**(9) Leases**

PSE has operating leases for buildings, real estate for operating facilities and the Puget LNG facility, land, and vehicles. Finance leases primarily represent buildings and equipment. PSE also has certain power purchase agreements that qualify as leases. The leases have remaining lease terms of less than a year to 43 years. PSE's ROU assets and lease liabilities include options to extend leases when it is reasonably certain that PSE will exercise that option.

Supplemental balance sheet information related to leases was as follows:

**(10) Other**

**Long-Term Debt**

On March 27, 2026, Puget Energy issued $450.0 million aggregate principal amount of 7.000% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056, Series A (the "Series A Notes") and $450.0 million aggregate principal amount of 7.250% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056, Series B (the "Series B Notes" and together with the Series A Notes, the "Notes") pursuant to a Junior Subordinated Indenture, dated as of March 27, 2026 (the "Base Indenture"), as supplemented by the First Supplemental Indenture dated as of March 27, 2026 (together with the Base Indenture, the "Junior Subordinated Indenture"). Interest on the Notes accrues from March 27, 2026 and is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2026. The Notes mature on September 15, 2056. The Series A Notes bear interest (i) from and including March 27, 2026 to, but excluding, September 15, 2031 at an annual rate of 7.000% and (ii) from and including September 15, 2031, during each Series A Interest Reset Period (as defined in the Junior Subordinated Indenture) at an annual rate equal to the average of the yields on actively traded United States Treasury securities adjusted to constant maturity, for five-year maturities, for the most recent five business days as of the most recent determination

------

date (the "Five-Year Treasury Rate"), plus 2.961%; provided, that the interest rate during any Series A Interest Reset Period will not reset below 7.000% (which equals the initial interest rate on the Series A Notes). The Series B Notes bear interest (i) from and including March 27, 2026 to, but excluding, September 15, 2036 at an annual rate of 7.250% and (ii) from and including September 15, 2036, during each Series B Interest Reset Period (as defined in the Junior Subordinated Indenture) at an annual rate equal to the Five-Year Treasury Rate as of the most recent determination date, plus 2.848%; provided, that the interest rate during any Series B Interest Reset Period will not reset below 7.250% (which equals the initial interest rate on the Series B Notes). So long as no Event of Default (as defined in the Junior Subordinated Indenture) with respect to the Notes has occurred and is continuing, Puget Energy may, at its option, defer interest payments on the Notes on one or more occasions for up to 10 consecutive years. In the event that Puget Energy were to exercise such right to defer interest on the Notes, Puget Energy would not be able to pay cash dividends during the periods in which such payments were deferred. Proceeds from the issuance of the Notes were used to pay down the outstanding balance on the Puget Energy senior secured credit facility and for general corporate purposes.

The Notes are Puget Energy's unsecured junior subordinated obligations and rank junior in right of payment to all of Puget Energy's Senior Indebtedness (as defined in the Junior Subordinated Indenture). The Notes rank equally in right of payment with all of Puget Energy's existing and future junior indebtedness.

**Liquidity Facilities and Other Financing Arrangements**

As of March 31, 2026, no amount was drawn and outstanding under Puget Energy's credit facility.

As of March 31, 2026, there was $140.0 million outstanding under the commercial paper program at PSE and no amount was drawn under PSE's credit facility. Outside of the credit facility, PSE maintains a standby letter of credit with TD Bank allowing for standby letter of credit postings of up to $300.0 million as a condition of transacting on the ICE NGX platform as well as participating in the Washington state carbon allowance auctions. As of March 31, 2026, $8.0 million was issued under the standby letter of credit with TD Bank in support of natural gas purchases and carbon allowance purchases. Additionally, PSE posted cash collateral of $64.5 million to Intercontinental Exchange for purchased power trading. Additionally, PSE secured rights to $70.4 million of GHG emission allowances under the CCA, which did not clear until April 1, 2026 and thus was included in restricted cash. In support of purchase power contracts, PSE posted no cash collateral and maintained two standby letters of credit in the amounts of $60.0 million and $11.9 million. In support of a funding participant contract, PSE has a $13.4 million standby letter of credit.

For further information on the Company's long-term and short-term debt, credit facilities and other financing arrangements, see Part II, Item 8, Note 7, "Long-Term Debt" and Note 8, "Liquidity Facilities and Other Financing Arrangements" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Utility Plant**

**Beaver Creek 2**

On March 30, 2026, PSE entered into a turbine supply agreement with GE Renewables North America, LLC to purchase 21 wind turbine generators for a total of $80.1 million. The wind turbine generators are expected to be delivered in 2028.

**Battle Butte Solar Project**

On November 14, 2025, PSE executed a membership interest purchase agreement to acquire development rights for a utility-scale solar project located in Stillwater County, Montana. On February 20, 2026, PSE entered into a purchase agreement for photovoltaic modules with an aggregate capacity of 178 MW direct current for this project. The total commitment under the module purchase agreement is approximately $60.0 million. As of March 31, 2026, an immaterial amount was recorded in Utility plant - Electric plant, including CWIP, related to this project.

**Beaver Creek Wind Project**

Beaver Creek is a utility-scale wind project located in Stillwater County, Montana, with nameplate capacity of 248 MW that commenced commercial operations in August 2025. As of March 31, 2026, a $183.5 million net ITC was recorded with a corresponding accumulated deferred ITC to the "Unamortized investment tax credit" financial statement line item, which will be passed back to customers over the life of the project.

On April 15, 2026 and April 16, 2026, PSE transferred the remaining portion of its ITC from the Beaver Creek wind project for net proceeds of $51.7 million and $46.3 million, respectively. PSE does not anticipate any additional tax credit transfers in 2026.

------

**Appaloosa Solar Project**

Appaloosa Solar Project is a utility-scale solar project located in Garfield County, Washington with an expected nameplate capacity of 142 MW that is expected to commence commercial operations in 2027. On December 22, 2023, PSE executed and closed a membership interest purchase agreement with HQC Solar Holdings 1, LLC for a 100% ownership interest in Appaloosa Solar Project LLC. Total consideration is expected to be $20.3 million, of which $18.6 million was paid as of March 31, 2026 and the remaining balance is expected to be paid during the remainder of 2026. On August 30, 2024, PSE entered into an Engineering, Procurement, and Construction agreement to complete the design and construction of the project. Total consideration is expected to be approximately $266.8 million. As of March 31, 2026, $110.4 million was recorded in Utility plant - Electric plant, including CWIP, related to this project.

**Colstrip**

Effective January 1, 2026, PSE transferred its 25% interest in Colstrip Units 3 and 4 to NorthWestern Energy. Consistent with the 2019 GRC, PSE accelerated the depreciation of Colstrip Units 3 and 4 to December 31, 2025. Additional costs not covered through repurposed PTCs and hydro-related treasury grants as directed in the 2017 GRC are being recovered through a separate Colstrip tariff as part of the 2022 GRC. On January 1, 2026, PSE applied abandonment accounting specific to Colstrip Units 3 and 4 assets that existed as of December 31, 2025, which were not material.

Separately, PSE maintains a 50% ownership interest in the retired Colstrip Units 1 and 2, which have been shut down and out of service since December 31, 2019.

For further information on the Company's utility plant, including resource acquisition projects, see Part II, Item 8, Note 6, "Utility Plant" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**(11) Segment Information**

Puget Energy operates one reportable segment, PSE, referred to as the regulated utility segment. PSE does not contain any additional reportable segments. The regulated utility operation generates, purchases and sells electricity and purchases, transports and sells natural gas. The service territory of PSE covers approximately 6,000 square miles in the state of Washington. Operations in addition to the regulated utility reportable segment, described as Other below, include the activities conducted at the holding company level and at Puget LNG, a non-regulated liquefied natural gas facility. The accounting policies of the regulated utility operating segment are the same as those described in <u>[Note 1](#i6847fb33bd864ee7a054df0113aceaeb_61)</u>, "Summary of Significant Accounting Policies" to the Combined Notes to Consolidated Financial Statements included in Part I, Item 1 of this report. The chief operating decision maker for both Puget Energy and PSE is the president and chief executive officer.

The chief operating decision maker assesses performance and decides resource allocation using net income for the regulated utility reportable segment. Net income is used by the chief operating decision maker to allocate resources, determine the Company's availability to fund capital expenditures, and assess overall performance. The chief operating decision maker uses net income by comparing actual results to budget to assess Company performance.

The following tables present financial information about the regulated utility segment and reconciliation to Puget Energy consolidated financial statements:

**Overview**

Puget Energy is an energy services holding company and substantially all of its operations are conducted through its wholly owned subsidiary PSE, a regulated electric and natural gas utility company. PSE is the largest electric and natural gas utility in the state of Washington, primarily engaged in the business of electric transmission, distribution and generation and natural gas distribution. Puget Energy's business strategy is to generate stable cash flows by offering reliable electric and natural gas service in a cost-effective manner through PSE. Puget Energy also has a wholly owned non-regulated subsidiary, Puget LNG, which has the sole purpose of owning and operating the non-regulated activity of the Tacoma liquefied natural gas (LNG) facility. Puget Holdings indirectly owns all of Puget Energy's common stock. Puget Holdings is owned by a consortium of long-term infrastructure investors including the British Columbia Investment Management Corporation

------

(BCIMC), the Alberta Investment Management Corporation (AIMCo), the Ontario Municipal Employees Retirement System (OMERS), PGGM Vermogensbeheer B.V., Macquarie Washington Clean Energy Investment, L.P., and the Ontario Teachers' Pension Plan Board. Puget Energy and PSE are collectively referred to herein as "the Company."

PSE generates revenue and cash flow primarily from the sale of electric and natural gas services to residential and commercial customers within a service territory covering approximately 6,000 square miles, principally in the Puget Sound region of the state of Washington. PSE continually balances its load requirements, generation resources, purchase power agreements and market purchases to meet customer demand. The Company's external financing requirements principally reflect the cash needs of its construction program, its schedule of maturing debt and certain operational needs. PSE requires access to bank and capital markets to meet its financing needs.

**Factors and Trends Affecting PSE's Performance** 

PSE's ongoing regulatory requirements and operational needs necessitate the investment of substantial capital in 2026 and will continue to do so in future years. Because PSE intends to seek recovery of such investments through the regulatory process, its financial results depend heavily upon favorable outcomes from that process. The principal business, economic and other factors that affect PSE's operations and financial performance include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The rates PSE is allowed to charge for its services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• PSE's ability to recover power costs that are subject to the Company's power cost adjustment mechanism that are included in rates, which are based on volume;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Weather conditions, including the impact of temperature on customer load; the impact of extreme weather events on budgeted maintenance costs; meteorological conditions such as snow-pack, stream-flow and wind-speed which affect power generation, supply and price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effects of climate change, including changes in the environment that may affect energy costs or consumption, increase the Company's costs, or adversely affect its operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory decisions allowing PSE to recover purchased power and fuel costs, on a timely basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• PSE's ability to supply electricity and natural gas, through company-owned generation, purchase power contracts or by procuring natural gas or electricity in wholesale markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Deferral of excess revenues if earnings exceed PSE's authorized rate of return (ROR) by more than 0.5%;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Availability and access to capital and the cost of capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory compliance costs, including those related to new and developing federal regulations of electric system reliability, state regulations of natural gas pipelines and federal, state and local environmental laws and regulations, such as the CCA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Wholesale commodity prices of electricity and natural gas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increasing capital expenditures with additional depreciation and amortization;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure to complete capital projects on schedule and within budget or the abandonment of capital projects, either of which could result in the Company's inability to recover project costs or refund previously collected revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in customer growth and customer usage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tax reform, the effect of lower tax rates, and regulatory treatment of excess deferred tax balances on rate base and customer rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• General economic conditions, such as inflation, in PSE's operational territory and its effects on customer growth and use-per-customer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Federal, state, and local taxes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Employee workforce factors, including potential strikes, work stoppages, transitions in senior management, and loss or retirement of key personnel and availability of qualified personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The effectiveness of PSE's risk management policies and procedures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cybersecurity incidents, cybersecurity attacks, data security breaches or other malicious acts that cause damage to the Company's generation and transmission facilities or information technology systems, or result in the release of confidential customer, employee, or Company information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Acts of war or terrorism locally or abroad, or the impact of civil unrest to infrastructure or preventing access to infrastructure and its impact on the supply chain and prices of goods and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Natural disasters such as wildfires, earthquakes, hurricanes, floods, landslides and windstorms or the rise in frequency and magnitude of extreme temperature events; possible accidents, explosions, fires or mechanical breakdowns affecting or caused by PSE's facilities or infrastructure; changes in legislation, regulation and government policies

------

including federal grant programs, trade restrictions and tariffs, and government permitting, authorizations or determinations and government staff reductions may increase the Company's costs, delay projects, interrupt service, impact PSE's generation, transmission and distribution systems, subject the Company to increased liability, and/or adversely affect its operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Risks due to health crises, such as epidemics and pandemics, including supply shortages, rising costs, disruption to vendor or customer relationships, the potential for reputational harm, the impact of government, business and company closure of facilities, customer or contract defaults, concerns of safety to employees and customers, potential costs due to quarantining of employees and work-from-home policies, and the Company's and vendor staffing levels resulting from vaccination mandates; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Legislative, regulatory, code, and/or ordinance changes, including executive orders, administrative orders, tariffs and trade restrictions and budget and efficiency measures, including any actual or potential reduction in the federal workforce, that impact operations, electric and natural gas availability, sales, transmission, costs and/or delivery.

**Regulation of PSE Rates and Recovery of PSE Costs** 

PSE's regulatory requirements, environmental compliance and operational needs require the investment of substantial capital in 2026 and future years. As PSE intends to seek recovery of these investments through the regulatory process, its financial results depend heavily upon outcomes from that process. The rates PSE is allowed to charge for its services influence its financial condition, results of operations and liquidity. PSE is highly regulated and the rates that it charges its retail customers are approved by the Washington Commission.

PSE's mandate to pursue electric conservation initiatives may have a negative impact on the electric business financial performance due to lost margins from lower sales volumes as variable power costs are not part of the decoupling mechanism. Washington law and the Washington Commission also set natural gas conservation achievement standards for PSE. The effects of achieving these standards will, however, have only a minor negative impact on the natural gas business's financial performance due to the natural gas business being mostly decoupled.

IOUs are required to file a forward-looking MYRP for two, three, or four years as part of a GRC filed with the Washington Commission. For the initial rate year, the Washington Commission is required to ascertain and determine the fair value for rate-making purposes of the property in service, as of the date that rates go into effect. While utilities are required to file a MYRP (at least two years in length), the Washington Commission is not required to approve them. To the extent the Washington Commission approves a MYRP, utilities are bound to the first and second year of the MYRP but may file for a new rate plan in years three or four. If a company earns greater than a half percent above its authorized rate of return on a regulated basis, revenues above that level must be deferred for refunds to customers or another determination by the Washington Commission in a subsequent adjudicative proceeding. The Washington Commission must also set performance measurements to assess a natural gas or electric company operating under a MYRP.

**General Rate Case Filing**

On February 27, 2026, PSE filed a GRC with the Washington Commission in Docket No. UE-260005 and Docket No. UG-260006. The filing included a three-year MYRP requesting an overall increase in electric and natural gas rates of 15.2% and 14.2% respectively in rate year one (expected to approximate calendar year 2027), 3.7% and 3.2%, respectively in rate year two (expected to approximate calendar year 2028) and 8.7% and 3.6% in rate year three (expected to approximate calendar year 2029). PSE requested a return on equity of 10.8% for all three rate years beginning in 2027 and requested an overall rate of return of 8.1% in rate year one and 8.2% in both rate years two and three.

**Access to Debt Capital** 

PSE relies on access to bank borrowings and short-term money markets as sources of liquidity and longer-term capital markets to fund its utility construction program, to meet maturing debt obligations and other capital expenditure requirements not satisfied by cash flow from its operations or equity investment from its parent, Puget Energy. Neither Puget Energy nor PSE have any outstanding debt whose maturity would accelerate upon a credit rating downgrade. However, a ratings downgrade could adversely affect the Company's ability to refinance existing or issue new long-term debt or obtain access to new or renew existing credit facilities, could increase the cost of issuing long-term debt and maintaining credit facilities and could impact the Company's ability to pay dividends. For example, under Puget Energy's and PSE's credit facilities, the borrowing costs increase as their respective credit ratings decline due to increases in credit spreads and commitment fees. If PSE is unable to access debt capital on reasonable terms, its ability to pursue improvements or generating capacity acquisitions, which may be relied on for future growth and to otherwise implement its strategy, could be adversely affected. PSE monitors the credit environment and expects to continue to be able to access the capital markets to meet its short-term and long-term borrowing needs. For additional information, see "Financing Program" included in this Item 2 of this report.

------

**Regulatory Compliance Costs and Expenditures** 

PSE's operations are subject to extensive federal, state and local laws and regulations, which impact electric system reliability, natural gas pipeline system safety and energy market transparency, among other areas. The Company's operations are also impacted by environmental laws and regulations related to air and water quality, climate change, avian and endangered species protection, waste handling, waste disposal, remediation of contaminated sites and the environmental impacts or other regulated impacts of new facilities. PSE must spend significant resources to fulfill requirements set by regulatory agencies, many of which have greatly expanded mandates on measures including resource planning, remediation, monitoring, pollution control equipment and emissions-related abatement.

In 2021, the Washington Legislature adopted the CCA, which establishes a greenhouse gases (GHG) emissions cap-and-invest program that requires covered entities to purchase allowances to cover their GHG emissions with a cap on available allowances beginning on January 1, 2023 that declines annually through 2050. The WDOE published final regulations to implement the program on September 29, 2022, which became effective on October 30, 2022. The WDOE also indicated that it will have subsequent rulemakings building off initial rulemaking while program implementation is underway. While the Washington Commission has approved the recovery of electric and natural gas CCA-related costs, which led to increased costs to customers, the Washington Commission also indicated these revenues are subject-to-refund, which introduces the risk that PSE may not be able to recover all costs. PSE faces continued risks associated with the program, including the evolving nature of the CCA rulemaking, related interpretation of the rules, credit volatility and unresolved recovery methodology for the CCA's impact on energy costs, company costs and customer rates.

Compliance with these or other future regulations, such as those pertaining to climate change, could require significant capital expenditures by PSE, which may adversely affect PSE's financial position, results of operations, cash flows and liquidity.

**Other Challenges and Strategies**

**Competition** 

PSE's electric and natural gas utility retail customers generally do not have the ability to choose their electric or natural gas supplier; therefore, PSE's business has historically been recognized as a natural and regulated monopoly. However, PSE faces competition from public utility districts and municipalities or efforts by citizens organizing to form such entities that want to establish their own government-owned utility, as a result of which PSE may lose a number of customers. PSE's natural gas customers may also elect to use heating oil, propane or other fuels instead of purchasing and using natural gas. PSE also faces increasing competition for sales to its retail customers through alternative methods of electric energy generation, including solar and other self-generation methods.

Additionally, PSE faces increasing competition from other entities, primarily in the technology sector, where several large companies have entered into power purchase agreements and/or acquired generation resources to meet their growing energy needs. This capacity will largely be used to fulfill commitments for additional cloud computing, artificial intelligence data centers, reduced carbon emissions and increase reliance on renewable energy sources. The increasing competitive pressure may impact the Company's ability to acquire generation and transmission resources and/or increase the cost to acquire such resources.

**Results of Operations**

**Puget Sound Energy**

The following discussion should be read in conjunction with the unaudited consolidated financial statements and the related notes included elsewhere in this document and provides significant items that impacted PSE's results of operations for the three months ended March 31, 2026 and March 31, 2025.

**Non-GAAP Financial Measures - Electric and Natural Gas Margins**

Financial information is prepared in accordance with GAAP, as well as two other financial measures, electric margin and natural gas margin, 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 includes adjustments that result in a presentation that is not defined by GAAP. The presentation of electric margin and natural gas margin is intended to supplement an understanding of PSE's operating performance. Electric margin and natural gas margin are used by PSE to determine whether PSE is collecting the appropriate amount of revenue from its customers in order to provide adequate recovery of operating costs, including interest and equity returns. PSE's electric margin and natural gas margin measures may not be comparable to other companies' electric margin and natural gas margin measures. Furthermore, these measures are not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance.

**Electric Margin** 

Electric margin represents electric sales to retail and transportation customers less the cost of generating and purchasing electric energy sold to customers, including transmission costs, to bring electric energy to PSE's service territory.

The following charts display the details of PSE's electric margin changes for the three months ended March 31, 2026 and 2025:

![360](psd-20260331_g3.jpg)

______________

<sup>\*</sup><sup>&nbsp;&nbsp;&nbsp;&nbsp;</sup>*Includes decoupling cash collections, ROR excess earnings, and decoupling 24-month revenue reserve.* 

**<u>Three Months Ended March 31, 2026 compared to 2025</u>**

**Electric Operating Revenue**

**Electric operating revenues** increased $233.6 million from the prior year primarily due to changes in the following key drivers: electric retail sales, sales to other utilities, decoupling revenue and transportation and other revenue. These items are discussed in detail below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Electric retail sales** increased $219.3 million primarily from rate increases resulting in an additional $265.5 million in sales compared to the prior year, partially offset by a decrease in retail electricity usage of 4.7% or $46.2 million. The increase in rates is primarily due to the power cost tariff filing effective January 1, 2026; this rate increase was partially offset by lower Schedule 111 rates due to the pass-back of CCA no-cost allowance values. See Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The decrease in retail usage was primarily due to a decrease in residential, commercial and industrial usage of 5.4%, 3.3% and 3.9%, respectively, due to a decrease in heating degree days of 10.0% in 2026 as compared to 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Sales to other utilities** decreased $43.2 million primarily due to a 20.7% decrease in wholesale sales volume driven by a 52.8% decrease in the average price of electric wholesale sales. Decreased wholesale sales volume was related to decreased supply, resulting from lower volumes of economic generation from PSE's energy supply assets in 2026 compared to 2025 which was influenced by lower wholesale power prices and Washington carbon prices that were

------

34.3% higher in 2026 as compared to 2025. Lower wholesale power prices were largely the result of higher regional energy supply driven by higher Mid-Columbia hydro production.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Decoupling revenue** increased $9.1 million which was attributable to $4.8 million and $4.3 million increases in delivery and fixed production cost deferral revenues, respectively. The increased revenue was driven primarily by decreased usage in the three months ended March 31, 2026 compared to the same period in 2025. This resulted in actual decoupling revenues being higher than allowed revenues by a less significant margin in 2026 as compared to 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Transportation and other revenue** increased $47.5 million primarily due to the start of a regulatory offset of CCA electric no-cost values of $71.4 million, which were passed back to customers as credits on billed revenue and included within electric retail revenues above, and an increase in transmission revenue of $3.3 million. The increases were partially offset by a decrease of non-core gas sales of $24.7 million driven by an increase in natural gas financial hedging costs plus average costs of non-core gas sold in 2026 that were higher than average non-core gas sales in the same period in 2025, and a decrease of $4.1 million related to deferrals under Schedule 129D. See "Regulation of PSE Rates and Recovery of PSE Costs" included in this Item 2 of this report.

**Electric Power Costs**

**Electric power costs** increased $111.5 million primarily due to changes in the following key drivers: purchased electricity, electric generation fuel and residential exchange credits. These items are discussed in detail below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Purchased electricity** increased $174.0 million primarily due to a 34.0% increase in wholesale electricity volumes and capacity purchases in 2026 compared to 2025, driven by lower-cost open market purchases as market conditions became more favorable relative to firm contract pricing and internal generation dispatch from PSE energy supply assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Electric generation fuel** decreased $67.0 million primarily driven by a $52.2 million decrease in natural gas fuel costs resulting from lower natural gas prices and a 95.1% decrease in gas-fired combustion turbine (CT) generation. The decrease in gas-fired CT generation was driven by reduced economic dispatch of PSE's gas-fired energy supply assets in 2026 compared to 2025, influenced by lower wholesale power prices and Washington carbon prices that were 34.3% higher as discussed above. Additionally, Colstrip fuel expense decreased $15.6 million due to the transfer of PSE's interest in Colstrip Units 3 and 4 to NorthWestern Energy on January 1, 2026, and thus Colstrip no longer served PSE customers in the three months ended March 31, 2026 compared to the same period in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Residential exchange credits** decreased by $4.5 million due to a 0.5% change in the amount of credits to be passed back to customers effective October 1, 2025 and a decrease in residential usage of 5.4%; see Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

------

**Natural Gas Margin**

Natural gas margin is natural gas sales to retail and transportation customers less the cost of natural gas purchased, including transportation costs to bring natural gas to PSE's service territory. The PGA mechanism passes through increases or decreases in the natural gas supply portion of the natural gas service rates to customers based upon changes in the price of natural gas purchased from producers and wholesale marketers or changes in natural gas pipeline transportation costs. PSE's margin or net income is not affected by changes under the PGA mechanism because over- and under-recoveries of natural gas costs included in baseline PGA rates are deferred and either refunded to or collected from customers in future periods.

The following charts display the details of PSE's natural gas margin changes for the three months ended March 31, 2026 and 2025:

**<u>Three Months Ended March 31, 2026 compared to 2025</u>**

**Natural Gas Operating Revenue**

**Natural gas operating revenue** increased $13.8 million primarily due to changes in the following key drivers: retail sales, decoupling revenue, and transportation and other revenue. These items are discussed in detail below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Natural gas retail sales revenue** increased $0.9 million primarily due to an increase in rates of $56.9 million partially offset by a decrease in natural gas load of 10.4%, or $56.0 million. The increase in rates is primarily driven by Schedule 111 that includes a charge for CCA natural gas allowance costs and a pass back of CCA auction proceeds, Schedule 129D Bill discount rate rider, Schedule 129 Low income program, Schedule 120 Conservation service rider, Schedule 140 Property tax tracker and a marginal increase in base rates from the 2024 GRC. See Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 for natural gas rate changes. The

------

decrease in natural gas load was driven by a decrease in heating degree days of 10.0% in the three months ended March 31, 2026 as compared to 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Decoupling revenue** increased $10.9 million primarily due to decreased natural gas usage, as mentioned above. This resulted in actual decoupling revenues being higher than the allowed revenues by a less significant margin in 2026 as compared to 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Transportation and other revenue** increased $5.2 million due to an increase of $9.0 million related to the regulatory offset of CCA auction proceeds, which were passed through to customers as credits on billed revenue included within natural gas retail revenues above. The increase was partially offset by a decrease of $3.9 million related to deferrals under Schedule 129D; for additional information see Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Natural Gas Energy Costs**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Purchased natural gas** expense decreased $14.5 million primarily due to a decrease in the PGA rates in November 2025 and a decrease in natural gas usage of 10.4%. For natural gas rate changes and details on the PGA, see Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The decrease was partially offset by an increase of $25.3 million in amortization of deferred CCA emission allowance costs, which were passed through to customers as billed revenue included within natural gas retail revenues above.

**Other Operating Expenses and Other Income (Deductions)**

The following chart displays the details of PSE's operating expenses and other income (deductions) for the three months ended March 31, 2026 and 2025:

![177](psd-20260331_g5.jpg)

**<u>Three Months Ended March 31, 2026 compared to 2025</u>&nbsp;&nbsp;&nbsp;&nbsp;**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Utility operations and maintenance** expense increased $42.4 million primarily due to increases in the following: (i) $22.1 million related to customer service expense, driven by an increase in Schedule 129 Low income program in electric and natural gas rates, (ii) $9.0 million of increased amortization of bad debt deferral recovery, (iii) $4.5 million related to increased outside service expenses driven by contractor spend across multiple business units and (iv) $3.8 million in general and administrative salaries. The increases were partially offset by a $3.6 million decrease in maintenance expenses specific to steam generation, which was primarily driven by the transfer of PSE's ownership interest in Colstrip Units 3 and 4 to NorthWestern Energy on January 1, 2026. For regulatory schedule information and rate changes, see Part II, Item 7, Management's Discussion and Analysis, "Regulation of PSE Rates and Recovery of PSE Costs" included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Depreciation and amortization expense** increased $11.3 million primarily due to a $9.3 million increase in conservation amortization from an increase in conservation rates effective May 1, 2025, see "Regulation of PSE Rates and Recovery of PSE Costs" included in this Item 2 of this report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Taxes other than income taxes** increased $20.8 million primarily due to an increase of $9.9 million and $8.9 million in municipal and state excise taxes, respectively, in 2026 compared to 2025.

 **Other Income, Interest Expense and Income Tax Expense** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Interest expense** increased $9.2 million primarily due to an increase of $7.0 million in interest expense due to the September 2025 PSE bond issuance and $3.5 million of AFUDC - debt.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Income tax expense** increased $10.0 million primarily driven by an increase in pre-tax book income in 2026 as compared to 2025.

------

**Puget Energy**

Primarily, all operations of Puget Energy are conducted through PSE. Puget Energy's net income (loss) for the three months ended March 31, 2026 and 2025 is as follows:

![153](psd-20260331_g6.jpg)

**<u>Three Months Ended March 31, 2026 compared to 2025</u>**

**Summary Results of Operation**

Puget Energy's net income increased by $55.2 million. This is primarily due to: (i) an increase in PSE's net income of $60.4 million and (ii) increased tax benefit of $4.3 million. The increases were partially offset by an increase in interest expense of $5.0 million, which was driven by interest expense accrued for Puget Energy's $600.0 million bond issuance in March 2025.

**Capital Requirements**

**Contractual Obligations and Commercial Commitments**

In addition to the contractual obligations and consolidated commercial commitments disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, during the three months ended March 31, 2026, the Company entered into new Electric Portfolio and Electric Wholesale Market Transaction contracts with estimated payment obligations totaling $94.2 million through 2027. For further information, see Part II, Item 8, Note 15, "Commitments and Contingencies" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Off-Balance Sheet Arrangements**

As of March 31, 2026, the Company had no off-balance sheet arrangements that have had or are reasonably likely to have a material effect on the Company's financial condition. The Company does have standby letter of credit arrangements. For more information, see <u>[Note 10](#i6847fb33bd864ee7a054df0113aceaeb_97)</u>, "Other" in the Combined Notes to Consolidated Financial Statements included in Part I, Item 1 of this report.

**Utility Construction Program**

The Company's construction programs for generating facilities, the electric transmission system, the natural gas and electric distribution systems and the Tacoma LNG facility are designed to meet regulatory requirements, support customer growth and improve energy system reliability. Construction expenditures, excluding equity AFUDC, totaled $412.2 million for the three months ended March 31, 2026. Presently planned utility construction expenditures, excluding equity AFUDC, are as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| **Capital Expenditure Projections** | | | | | |
| (Dollars in Millions) | 2026 | 2027 | 2028 | 2029 | 2030 |
| Total energy delivery, technology and facilities expenditures | $2079.0 | $2812.0 | $3182.0 | $3308.0 | $3112.0 |

---

The program is subject to change based upon general business, economic and regulatory conditions. Utility construction expenditures and any new generation resource expenditures may be funded from a combination of sources, which may include cash from operations, short-term debt, long-term debt and/or equity. PSE's planned capital expenditures may result in a level of spending that will exceed its cash flow from operations. As a result, execution of PSE's strategy is dependent in part on continued access to capital markets.

**<u>Three Months Ended March 31, 2026 compared to 2025</u>**

**Cash generated from operations** for the three months ended March 31, 2026 increased by $24.7 million, which includes a net income increase of $60.4 million. The following are significant factors that impacted PSE's cash flows from operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Cash flows resulting from non-cash items** increased $31.1 million primarily due to: (i) a $10.2 million increase due to lower usage of CCA no cost emission allowances compared to values passed back in Schedule 111 for electric, (ii) an increase of $9.3 million in conservation amortization, (iii) a change in equity AFUDC of $6.1 million, (iv) an increase of $5.6 million related to amortization of deferred return on PSE's share of the Tacoma LNG investment, (v) an increase in deferred taxes of $4.9 million and (vi) an increase in depreciation and amortization of $2.0 million. The increases were partially offset by: (i) a decrease of $5.5 million related to the deferral of energy exchange costs and (ii) $2.4 million of ITC amortization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash flows resulting from changes in working capital** decreased $36.7 million primarily due to: (i) an increase in cash outflow of $26.0 million due to the timing of accounts receivable and unbilled revenue collections, as the balance of accounts receivable and unbilled revenue increased $81.2 million in 2026 compared to an increase of $55.2 million in 2025, (ii) accounts payable decreased faster in 2026 compared to 2025, which led to increased cash outflow of $15.7 million, (iii) higher incentive payment and timing of accrued salaries and wages led to an increased cash outflow

------

of $8.1 million, (iv) change in natural gas and fuel inventory led to decreased cash inflow of $7.8 million, (v) timing of payments and accrued interest led to a $7.0 million cash outflow and (vi) increased cash outflow of $5.0 million due to higher inventory of plant material and supplies. The decreases were partially offset by: (i) cash inflow of $24.1 million due to the change in taxes payable, (ii) cash inflow of $3.7 million due to the change in prepayment of insurance and employee benefits and (iii) cash inflow of $2.4 million due to the change in prepayment of purchased electricity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Cash flows resulting from regulatory assets and liabilities** increased $27.9 million primarily due to the recovery of prior year PCA imbalances totaling $42.0 million. The increase was partially offset by $18.1 million cash outflow related to revenue decoupling mechanism, which had cash inflows of $34.2 million in 2026 compared to $52.3 million in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Cash flows resulting from purchased gas adjustment** decreased $32.9 million, primarily due to a $39.5 million decrease in allowed PGA recovery in 2026 compared to 2025 which was partially offset by a $6.6 million decrease in actual natural gas cost.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Cash flow resulting from GHG emission allowances** decreased $16.8 million due to purchases made to obtain the Washington emission allowances for GHG emissions associated with the Company's electric and natural gas business activities in compliance with the CCA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Other non-current assets and liabilities** decreased $8.4 million, which is primarily due to $13.2 million increased cash outflow driven by higher long-term incentive payments in 2026 compared to 2025 and partially offset by $3.2 million cash inflow due to an increase in network upgrade refund liability.

**<u>Three Months Ended March 31, 2026 compared to 2025</u>**

**Cash generated from operations** for the three months ended March 31, 2026, in addition to the changes discussed at PSE above, decreased by $23.4 million compared to the same period in 2025, which includes a net income decrease of $5.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Changes in cash flow resulting from non-cash items** decreased $2.9 million primarily due to a $2.9 million change in deferred taxes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Changes in cash flow resulting from working capital** decreased $15.8 million, largely driven by a $17.2 million interest payment in March 2026. This outflow was partially offset by a $3.3 million cash inflow from changes in interest accruals.

**Financing Program**

The Company's external financing requirements principally reflect the cash needs of its construction program, its schedule of maturing debt and certain operational needs. The Company anticipates refinancing the redemption of bonds or other long-term borrowings with its credit facilities and/or the issuance of new long-term debt. Access to funds depends upon factors such as Puget Energy's and PSE's credit ratings, prevailing interest rates and investor receptivity to investing in the utility industry, Puget Energy and PSE. The Company believes it has sufficient liquidity through its credit facilities and access to capital markets to fund its needs over the next twelve months.

Proceeds from PSE's short-term borrowings and sales of commercial paper are used to provide working capital and the interim funding of utility construction programs. Puget Energy and PSE continue to have reasonable access to the capital and credit markets.

------

In the second quarter of 2025, Moody's, S&P and Fitch issued annual rating agency reports and affirmed both Puget Energy (Baa3/BBB-/BBB-) and PSE (Baa1/BBB/BBB+) credit ratings and retained stable outlooks from all three agencies. Thus, as of March 31, 2026, both Puget Energy and PSE have stable outlooks from Moody's, S&P and Fitch. Although neither Puget Energy nor PSE have any outstanding debt whose maturity would be accelerated upon a ratings downgrade, Management continually monitors the credit rating environment for both Puget Energy and PSE as a credit rating downgrade may increase the cost of borrowing for Puget Energy and PSE in future long-term financings or under their existing credit facilities. Any increase in the cost of borrowing could negatively impact Puget Energy and PSE's future results of operations as well as future liquidity, access to debt capital resources and financial condition. Additionally, a ratings downgrade could impact the Company's ability to issue dividends. A downgrade to Puget Energy and PSE's credit ratings would not impact debt covenants under our existing credit facilities nor would it impact other contracts, as neither include credit rating triggering event clauses. A credit rating decrease for PSE could result in increased cash collateral required for commodity contracts, which would adversely affect PSE's liquidity. Management cannot predict with certainty the actions credit agencies may take, if any, in response to weaker near-term credit metrics, regulatory and rate recovery uncertainties, and management's efforts to contain the growth of capital and operating expenditures. Containing the growth of capital and operating expenditures will be limited, over the near term, due to continuing strategic and risk mitigation imperatives and the necessity of providing safe, reliable and resilient service levels to customers.

**Puget Sound Energy** 

**Debt Restrictive Covenants**

PSE's future long-term financings and ability to issue additional secured debt may be limited by certain restrictions contained in its electric and natural gas mortgage indentures. Under the most restrictive tests, at March 31, 2026, PSE could issue:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Approximately $4.0 billion of additional first mortgage bonds under PSE's electric mortgage indenture based on approximately $5.8 billion of electric bondable property available for issuance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Approximately $3.1 billion of additional first mortgage bonds under PSE's natural gas mortgage indenture based on approximately $4.5 billion of natural gas bondable property available for issuance.

**Dividend Payment Restrictions**

Pursuant to the terms of the Washington Commission merger order, PSE may not declare or pay dividends if PSE's common equity ratio, calculated on a regulatory basis, is 44.0% or below except to the extent a lower equity ratio is ordered by the Washington Commission. Also, pursuant to the merger order, PSE may not declare or make any distribution unless on the date of distribution PSE's corporate credit/issuer rating is investment grade, or, if its credit ratings are below investment grade, PSE's ratio of EBITDA to interest expense for the most recently ended four fiscal quarter periods prior to such date is equal to or greater than 3.0 to 1.0. The common equity ratio, calculated on a regulatory basis, was 49.0% at March 31, 2026, and the EBITDA to interest expense ratio was 5.4 to 1.0 for the twelve months ended March 31, 2026.

PSE's ability to pay dividends is also limited by the terms of its credit facilities, pursuant to which PSE is not permitted to pay dividends during any Event of Default (as defined in the facilities), or if the payment of dividends would result in an Event of Default, such as failure to comply with certain financial covenants.

At March 31, 2026, the Company was in compliance with all applicable covenants, including those pertaining to the payment of dividends.

For more information on PSE's credit facilities, long-term debt, demand promissory note, and shelf registrations see <u>[Note 10](#i6847fb33bd864ee7a054df0113aceaeb_97)</u>, "Other" included in Part I, Item 1 of this report and Part II, Item 8, Note 7, "Long-Term Debt" and Note 8, "Liquidity Facilities and Other Financing Arrangements" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Puget Energy**

**Dividend Payment Restrictions**

Puget Energy's ability to pay dividends is also limited by the merger order issued by the Washington Commission in 2009. Pursuant to the merger order, Puget Energy may not declare or make a distribution unless on such date Puget Energy's ratio of consolidated EBITDA to consolidated interest expense for the four most recently ended fiscal quarters prior to such date is equal to or greater than 2.0 to 1.0. Puget Energy's EBITDA to interest expense was 3.9 to 1.0 for the twelve months ended March 31, 2026.

Puget Energy's ability to pay dividends is also limited by the terms of its Junior Subordinated Notes, which Puget Energy may, at its option, defer interest payments on the Junior Subordinated Notes on one or more occasions for up to 10 consecutive years, so long as no Event of Default (as defined in the Junior Subordinated Indenture) has occurred and is continuing. In the

------

event that Puget Energy were to exercise such right to defer interest payments on the Junior Subordinated Notes, Puget Energy would not be able to pay cash dividends during the periods in which such payments were deferred.

At March 31, 2026, the Company was in compliance with all applicable covenants, including those pertaining to the payment of dividends.

For further information on Puget Energy's credit facilities, shelf registrations, and long-term debt, see <u>[Note 10](#i6847fb33bd864ee7a054df0113aceaeb_97)</u>, "Other" included in Part I, Item 1 of this report and Part II, Item 8, Note 7, "Long-Term Debt" and Note 8, "Liquidity Facilities and Other Financing Arrangements" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

For critical accounting estimates, see Part II, Item 7, Management's Discussion and Analysis, "Critical Accounting Estimates" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Item 3. &nbsp;&nbsp;&nbsp;&nbsp;**<u>Quantitative and Qualitative Disclosure about Market Risk</u>**

The Company is exposed to various forms of market risk, consisting primarily of adverse changes in commodity prices, counterparty credit risk, as well as interest rate risk. PSE actively manages market risk and maintains risk policies and procedures designed to discourage unauthorized risk-taking, reduce commodity price volatility, and manage the various risks inherent to the energy portfolio. There have been no material changes to market risks affecting the Company from those set forth in Part II, Item 7A - "Quantitative and Qualitative Disclosures about Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Commodity Price Risk**

The nature of serving regulated electric and natural gas customers with its portfolio of owned and contracted electric generation resources exposes PSE and its customers to some volumetric and commodity price risks. PSE's Energy Risk Management Committee establishes energy risk management policies and procedures to manage commodity and volatility risks and the related effects on credit, tax, accounting, financing and liquidity.&nbsp;&nbsp;&nbsp;&nbsp;

PSE's objective is to minimize commodity price exposure and risks associated with volumetric variability in the natural gas and electric portfolios. It is not engaged in the business of assuming risk for the purpose of speculative trading. PSE hedges open natural gas and electric positions to reduce both the portfolio risk and the volatility risk in prices.

**Counterparty Credit Risk**

PSE is exposed to credit risk primarily through buying and selling electricity and natural gas to serve customers. Credit risk is the potential loss resulting from a counterparty's non-performance under an agreement. PSE manages credit risk with policies and procedures for counterparty analysis and measurement, monitoring and mitigation of exposure. Additionally, PSE has entered into commodity master arrangements (i.e., WSPP, ISDA or NAESB) with its counterparties to mitigate credit exposure.

**Interest Rate Risk**

The Company believes its interest rate risk primarily relates to the use of short-term debt instruments, variable-rate leases, and anticipated long-term debt financing needed to fund capital requirements. The Company manages its interest rate risk through the issuance of mostly fixed-rate debt with varied maturities. The Company utilizes internal cash from operations and borrowings under its commercial paper program and its credit facilities to meet short-term funding needs. During periods of financial market or interest rate volatility, the Company may utilize its credit facilities for short term funding needs instead of the commercial paper program. Credit facility borrowings are based on a more stable base rate and the credit spread is fixed. Short-term obligations are commonly refinanced with fixed-rate bonds or notes when needed and when interest rates are considered favorable. The Company may also enter into swaps or other financial hedge instruments to manage the interest rate risk associated with the debt.
