CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report and other presentations made by Hawaiian Electric Industries, Inc. (HEI) and Hawaiian Electric Company, Inc. (Hawaiian Electric) and their subsidiaries contain “forward-looking statements,” which include statements that are predictive in nature, depend upon or refer to future events or conditions and usually include words such as “will,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “predicts,” “estimates” or similar expressions. In addition, any statements concerning future financial performance, ongoing business strategies or prospects or possible future actions are also forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties and the accuracy of assumptions concerning HEI and its subsidiaries (collectively, the Company), the performance of the industries in which they do business and economic, political and market factors, among other things. These forward-looking statements are not guarantees of future performance and actual results and financial condition may differ materially from those indicated in the forward-looking statements.

Risks, uncertainties and other important factors that could cause actual results to differ materially from those described in forward-looking statements and from historical results include, but are not limited to, the following:

•the potential for further trade policy changes under the current administration could disrupt our supply chains and increase costs, e.g., the Utilities’ capital goods and equipment purchases and those of its independent power producers (IPPs) that contain components, sub-components, or raw materials sources from outside the U.S. could experience increases in costs, which could threaten the viability of projects and impact our ability to meet customer demand and the Utilities’ ability to achieve renewable portfolio standards (RPS) goals;

•the impact of the Maui windstorm and wildfires, including liabilities in excess of settlement amounts and potential regulatory penalties, which may result in significant costs that may be unrecoverable (or not reimbursed on a timely basis) through insurance and/or rates;

•an increase in insurance premiums and the inability to fully recover premiums through rates or the potential inability to obtain wildfire and general liability insurance coverage at reasonable rates, if available at all;

•the ability to raise the amount of capital necessary on reasonable terms, if at all, for the Company’s and the Utilities’ contribution to the Maui wildfire tort litigation settlement in order to alleviate future conditions that may cause substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern;

•potential further dilution to existing shareholders if the Company raises funds by issuing additional equity or equity-linked securities;

•the inability to execute financing plans to alleviate future conditions that may cause substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern prior to the issuance of their respective annual financial statements, which could result in an event of default and an acceleration of the Company’s and the Utilities’ debt and lead to filing for bankruptcy protection if waivers from lenders are not received;

•extreme weather events, including windstorms and other natural disasters, particularly those driven or exacerbated by evolving climate dynamics, which could increase the risk of the Utilities’ equipment being damaged, becoming inoperable or contributing to a wildfire;

•future suspension, material reduction or extended delay in dividends or other distributions from operating subsidiaries to HEI;

•further downgrades by securities rating agencies in their ratings of the securities of HEI and Hawaiian Electric and their impact on results of financing efforts;

•the risks of suffering losses and incurring liabilities that are uninsured (e.g., damages to the Utilities’ transmission and distribution system and losses from business interruption) or underinsured (e.g., losses not covered as a result of insurance deductibles or other exclusions or exceeding policy limits), and the risks associated with the operation of transmission and distribution assets and power generation facilities, including public and employee safety issues, and assets causing or contributing to wildfires;

•international, national and local economic and political conditions—including the state of the Hawaii tourism, defense and construction industries; the strength or weakness of the Hawaii and continental U.S. real estate markets; decisions concerning the extent of the presence of the federal government and military in Hawaii; the implications and potential impacts of federal government shutdowns, including the impact to the Utilities’ customers’ ability to pay their electric bills and the impact on the State of Hawaii economy; the implications and potential impacts of U.S. and foreign capital and credit market conditions and federal, state and international responses to those conditions; the potential impacts of global and local developments (including global economic conditions and uncertainties, unrest, terrorist acts, wars, conflicts, political protests, deadly virus epidemic or other crisis); the effects of changes that have or may occur in U.S. policy, such as with respect to immigration and trade; and pandemics;

•the ability to adequately address risks and capitalize on opportunities related to the Company’s and the Utilities’ sustainability priority areas, which include safety, reliability and resilience, including relating to wildfires and other extreme weather events, decarbonization, economic health and affordability, secure digitalization, human capital management, employee engagement, and climate-related risks and opportunities;

•citizen activism, including civil unrest, especially in times of severe economic depression and heightened social and political divisions, which could negatively impact customers and employees, impair the ability of the Company and the Utilities to operate and maintain their facilities in an effective and safe manner, and citizen or stakeholder activism that could delay the construction, increase project costs or preclude the completion of third-party or Utility projects that are required to meet electricity demand, resilience and reliability objectives and RPS and other climate-related goals;

•the effects of actions or inaction of the U.S. government or related agencies, including those related to the U.S. debt ceiling or budget funding, monetary policy, trade policy, energy and environmental policy, and other policy and regulatory changes advanced or proposed by the current administration;

•weather, natural disasters (e.g., hurricanes, earthquakes, tsunamis, lightning strikes, lava flows and the effects of evolving climate dynamics, such as more severe storms, flooding, droughts, heat waves, and rising sea levels) and wildfires, including their impact on the resilience and reliability and cost of the Company’s and Utilities’ operations, and the economy;

•the timing, speed and extent of changes in interest rates and the shape of the yield curve, which could result in higher borrowing costs and changes in market liquidity;

•the continued ability of the Company and the Utilities to access the credit and capital markets to fund necessary investments and expenditures (e.g., to obtain short-term and long-term debt financing, including lines of credit, and, in the case of HEI, to issue common stock) under volatile and challenging market conditions, and the potential higher cost of such financings, if available, and due to the uncertainties associated with the costs related to the Maui windstorm and wildfires;

•the risks inherent in changes in the value of the Company’s pension and other retirement plan assets, and the risks inherent in changes in the value of the Company’s pension liabilities, including changes driven by stock market values, interest rates and mortality improvements;

•changes in laws, regulations (including tax regulations), market conditions, interest rates and other factors that result in changes in assumptions used to calculate retirement benefits costs and funding requirements;

•the potential delay by the Public Utilities Commission of the State of Hawaii (PUC) in considering (and potential disapproval of actual or proposed) proposals related to wildfire safety, renewable energy or grid resiliency, among others, and related costs; reliance by the Utilities on outside parties such as the State, IPPs and developers; supply-chain challenges; and uncertainties surrounding technologies, solar power, wind power, biofuels, liquefied natural gas, environmental assessments required to meet RPS and other climate-related goals; the impacts of implementation of the wildfire mitigation, renewable energy and resilience proposals on future costs of electricity and potential penalties imposed by the PUC for delays in the commercial operations of renewable energy projects;

•the ability of the Utilities to develop, execute and recover the implementation costs of the Utilities’ action plans included in their Integrated Grid Plan, which was accepted by the PUC in 2024, due to the recent issuance of the PUC’s 2024 Inclinations on the Future of Energy in Hawaii, Governor Josh Green’s Executive Order No. 25-01, Accelerating Hawaii’s Transition Toward 100 Percent Renewable Energy, and the Hawaii State Energy Office’s Alternative Fuel, Repowering and Energy Transition Study on the aforementioned plans of the Utilities;

•the ability of the Utilities to recover undepreciated cost of fossil fuel generating units, if they are required to be retired before the end of their expected useful life;

•capacity and supply constraints or difficulties, especially if generating units (utility-owned or IPP-owned) fail or measures such as demand-side management, distributed generation, combined heat and power or other firm capacity supply-side resources fall short of achieving their forecasted benefits or are otherwise insufficient to reduce or meet peak demand;

•high and/or volatile fuel prices, which increases working capital requirements and customer bills, or delivery of adequate fuel by suppliers (including as a result of the Iran war, Russia-Ukraine war and conflicts in the Middle East), which could affect the reliability of utility operations, and the continued availability to the Utilities of their Energy Cost Recovery Clauses (ECRCs);

•the continued availability to the Utilities or modifications of other cost recovery mechanisms, including the Purchased Power Adjustment Clauses (PPACs), annual revenue adjustment (ARA) and pension and postretirement benefits other than pensions (OPEB) tracking mechanisms, and the continued decoupling of revenues from sales to mitigate the effects of declining kilowatt-hour sales;

•the ability of the Utilities to recover increasing or additional costs (e.g., due to trade policies imposed by the current administration or other factors impacting prices) and earn a reasonable return on capital investments not covered by the ARA, while providing the customer dividend required by performance-based regulation (PBR);

•the impact from the PUC’s modification of the PBR for the Utilities pursuant to Act 005, Session Laws 2018, including the potential changes to existing and/or addition of new Performance Incentive Mechanisms (PIMs), third-party proposals adopted by the PUC, and the implications of not achieving performance incentive goals;

•the impact of fuel price levels and volatility on customer satisfaction and political and regulatory support for the Utilities;

•unfavorable changes in economic conditions, such as sustained inflation, higher interest rates or recession, that negatively impact the ability of the Company’s customers to pay their utility bills and increase operating costs of the Utilities that cannot be passed on to, or recovered, from customers;

•the risks associated with increasing reliance on renewable energy, including the availability and cost of non-fossil fuel supplies for renewable energy generation and the operational impacts and related cost impacts of adding intermittent sources of renewable energy to the electric grid;

•the growing risk that energy production from renewable generating resources may be curtailed and the interconnection of additional resources will be constrained as more generating resources are added to the Utilities’ electric systems and as customers reduce their energy usage;

•the ability of IPPs to deliver the firm capacity anticipated in their power purchase agreements (PPAs);

•the potential that, as IPP contracts near the end of their terms, there may be less economic incentive for the IPPs to make investments in their units to ensure the availability of their units;

•the ability of the Utilities to negotiate, periodically, favorable agreements for significant resources such as fuel supply contracts and collective bargaining agreements and avoid or mitigate labor disputes and work stoppages;

•new technological developments that could affect the operations and prospects of the Utilities or their competitors such as the commercial development of energy storage and microgrids;

•the potential that cyber or physical security incidents, including potential incidents at HEI, its subsidiaries (including at electric utility plants), third-party service providers, contractors and customers with whom they have shared data (IPPs, distributed energy resources aggregators and customers enrolled under distributed energy resources programs) and incidents at data processing centers used, to the extent not prevented by physical and cybersecurity protections, could result in operational disruption; the misappropriation or loss of confidential or proprietary assets, information or data, including customer, employee, financial, or operating system information, or intellectual property; corruption of data; or potential costs, lost revenues, litigation, or reputational harm;

•failure to achieve remaining cost savings commitment related to the management audit recommendations of $6.6 million per year during the multi-year rate period (MRP) from June 2021 to May 2026, and continuing until the second MRP begins;

•federal, state, county and international governmental and regulatory actions, such as existing, new and changes in laws, rules and regulations applicable to HEI and the Utilities (including changes in taxation and tax rates, increases in capital requirements, regulatory policy changes, environmental laws and regulations (including resulting compliance costs and risks of fines and penalties and/or liabilities), the regulation of greenhouse gas emissions, governmental fees and assessments, and potential carbon pricing or “cap and trade” legislation that may fundamentally alter costs to produce electricity and accelerate the move to renewable generation);

•the impact from the PUC’s implementation of wheeling for the Utilities, including cost shifting and customer equity considerations, the potential increased competition, and other legal and technical implications, pursuant to Act 266, which authorizes wheeling of renewable energy and requires the PUC to establish associated policies and procedures;

•developments in laws, regulations and policies governing protections for historic, archaeological and cultural sites, and plant and animal species and habitats, as well as developments in the implementation and enforcement of such laws, regulations and policies;

•discovery of conditions that may be attributable to historical chemical releases, including any necessary investigation and remediation, and any associated enforcement, litigation or regulatory oversight;

•decisions by the PUC in rate cases and other proceedings (including the risks of delays in the timing of decisions, adverse changes in final decisions from interim decisions and the disallowance of project costs as a result of adverse regulatory audit reports or otherwise);

•decisions by the PUC and by other agencies and courts on land use, environmental and other permitting issues (such as required corrective actions, restrictions and penalties that may arise, such as with respect to environmental conditions or RPS);

•the risks associated with the geographic concentration of HEI’s businesses;

•changes in accounting principles applicable to HEI and its subsidiaries, including the adoption of new U.S. accounting standards, the potential discontinuance of regulatory accounting related to PBR or other regulatory changes, the effects of potentially required consolidation of variable interest entities (VIEs), or required finance lease or on-balance-sheet operating lease accounting for PPAs with IPPs;

•the final outcome of tax positions taken by HEI and its subsidiaries;

•the ability to effectively utilize federal and state net operating loss carryforwards;

•the ability to service the non-recourse debt of Mahipapa, LLC, the last remaining operating subsidiary of Pacific Current, LLC, a non-regulated subsidiary of the Company, if the Company is unable to complete the sale of Mahipapa, LLC;

•the Company’s reliance on third parties and the risk of their non-performance; and

•other risks or uncertainties described elsewhere in this report (e.g., Item 1A. Risk Factors) and in other reports previously and subsequently filed by HEI and/or Hawaiian Electric with the Securities and Exchange Commission (SEC).

Forward-looking statements speak only as of the date of the report, presentation or filing in which they are made. Except to the extent required by the federal securities laws, HEI, Hawaiian Electric, Pacific Current and their subsidiaries undertake no obligation to publicly update or revise any forward-looking statements, whether written or oral and whether as a result of new information, future events or otherwise.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1 · Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial information, the instructions to SEC Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In preparing the unaudited condensed consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited condensed consolidated financial statements and the following notes should be read in conjunction with the audited consolidated financial statements and the notes thereto in HEI’s and Hawaiian Electric’s Form 10-K for the year ended December 31, 2025.

In the opinion of HEI’s and Hawaiian Electric’s management, the accompanying unaudited condensed consolidated financial statements contain all material adjustments required by GAAP to fairly state consolidated HEI’s and Hawaiian Electric’s financial positions as of March 31, 2026 and December 31, 2025 and the results of their operations and cash flows for the three months ended March 31, 2026 and 2025. All such adjustments are of a normal recurring nature, unless otherwise disclosed below or in other referenced material. Results of operations for interim periods are not necessarily indicative of results for the full year.

Recent accounting pronouncements.

Income statement disclosures. In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). The guidance requires more detailed information about specified categories of expenses included in certain captions presented on the face of the income statement. ASU No. 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this amendment on the Company’s consolidated financial statements.

Accounting for Internal-use software. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software: Targeted Improvements to the Accounting for Internal-Use Software. The guidance removes all references to project stages in software development and requires capitalization of internal-use software costs to begin when management has authorized and committed to funding the project and it is probable the project will be completed and used to perform the intended function. ASU No. 2025-06 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of this amendment on the Company’s consolidated financial statements.

Accounting for government grants. In December 2025, the FASB issued ASU No. 2025-10, Accounting for Government Grants Received by Business Entities. The ASU adds guidance on the recognition, measurement and presentation of government grants received by business entities. ASU No. 2025-10 is effective for annual reporting periods beginning after December 15, 2028, and for interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of this amendment on the Company’s consolidated financial statements.

Note 2 · Maui windstorm and wildfires

On August 8, 2023, a number of brush fires in the West Maui (Lahaina) and Upcountry Maui areas caused widespread property damage, including damage to property of the Utilities, and 102 confirmed fatalities in Lahaina (the Maui windstorm and wildfires). The Maui windstorm and wildfires were fueled by extreme winds and drought-like conditions in those parts of Maui.

Restoration costs and recoveries. The Utilities are continuing restoration work to rebuild portions of the electric system in Lahaina to ensure safe and reliable power to customers. Restoration efforts include the rebuilding of electrical lines along former routes in the Lahaina area with the installation of new interim steel and wood poles and electrical equipment. Ongoing work is focused on reestablishing electrical service to homes as they are being built.

The Public Utilities Commission of the State of Hawaii (PUC) has issued orders authorizing deferred accounting treatment for certain incremental non-labor expenses related to the Maui windstorm and wildfires incurred from August 8, 2023 through December 31, 2025. The approval pertains only to deferred cost treatment for expenses that are not already part of base rates; any actual recovery of deferred costs will be the subject of a separate application(s). As of March 31, 2026, the Utilities have deferred $80.5 million of these incremental costs to a regulatory asset.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

The Utilities are actively seeking recovery of damages to rebuild the covered electrical infrastructure from their insurers and have received insurance reimbursements of $10 million to date; however, the timing and amount of any future insurance recoveries remain indeterminable at this time and as such, any additional insurance receivable has not been recorded. As of March 31, 2026, the Utilities have $490 million of property insurance coverage remaining, net of insurance recoveries.

Tort-related legal claims. HEI and the Utilities each were named in several thousand lawsuits related to the Maui windstorm and wildfires. Nearly all of these civil lawsuits, including one putative class action, were pending in the Maui Circuit Court. Two putative class actions and one individual action are pending in federal court. These state and federal lawsuits (collectively, tort-related legal claims) named as defendants HEI, the Utilities, and others, including the County of Maui, the State of Hawaii and related state entities, private landowners and developers, and telecommunications companies. Most of these lawsuits alleged that the defendants were responsible for, and/or negligent in failing to prevent or respond to the wildfires that led to property destruction and loss of life. The plaintiffs sought to recover damages and other costs, including punitive damages for, among other things, personal injury, wrongful death, emotional distress, property damage, and inverse condemnation. One lawsuit asserting similar theories and claims was filed by the County of Maui against HEI and the Utilities. A separate lawsuit was filed by Spectrum Oceanic, LLC against HEI and the Utilities and other defendants, and other lawsuits were filed by approximately 200 subrogation insurers against HEI, the Utilities, a private landowner, and telecommunications companies. Defendants asserted cross-claims against one another for indemnification, contribution, and subrogation.

One ‘Ohana Initiative. The One ‘Ohana Initiative is a $175 million humanitarian aid fund with the objective to compensate, in an expedited manner and as an alternative to litigation, those who lost loved ones and those who suffered severe injuries in the Maui windstorm and wildfires. The One ‘Ohana Initiative was funded with contributions from the State of Hawaii, the County of Maui, Kamehameha Schools, Hawaiian Electric, and other parties. Hawaiian Electric’s contribution of $75 million was fully funded by its insurance carriers, and no additional outlay is required.

Class Settlement Agreement and Individual Settlement Agreement. Effective November 1, 2024, HEI and Hawaiian Electric entered into two definitive settlement agreements (collectively, the Settlement Agreements) to settle the tort-related legal claims in the litigation arising out of the Maui windstorm and wildfires (expressly excluding securities and derivative actions) on a global basis without any admission of liability. Under the Settlement Agreements, subject to certain conditions (including those described below), HEI and Hawaiian Electric, along with other defendants (the State of Hawaii, the County of Maui, Kamehameha Schools, entities affiliated with the West Maui Land Co., Hawaiian Telcom, and Spectrum/Charter Communications) agreed to settle the claims of those who filed lawsuits in state and federal courts, or who may have claims but have not yet filed lawsuits, in connection with the Maui windstorm and wildfires. One Settlement Agreement is between the defendants, class counsel, and class plaintiffs (the Class Settlement Agreement), and the other is between the defendants and over 30 lawyers representing thousands of individual plaintiffs who brought their own lawsuits or who hired attorneys but did not file lawsuits (the Individual Settlement Agreement).

Under the Settlement Agreements, HEI and Hawaiian Electric are obligated to contribute a total of $1.99 billion (out of a total defendant contribution of approximately $4.04 billion), which includes the $75 million previously contributed to the One ‘Ohana Initiative. The total settlement amount is to be divided between two settlement funds, one for the benefit of individual plaintiffs, and the other for the benefit of the class plaintiffs. HEI and Hawaiian Electric must pay such remaining amounts in four equal annual installments of approximately $479 million. HEI and Hawaiian Electric have the option to accelerate the payments, in whole or in part, with such accelerated payments to be discounted at a rate of 5.5% per annum. Additionally, under the Settlement Agreements, HEI and Hawaiian Electric are obligated to contribute a share to the settlement administration fees only if certain other sources are exhausted when those fees are due, for which, $3.5 million was accrued as of March 31, 2026, based on the best estimate at that time.

HEI and Hawaiian Electric determined that making payments under the terms of the Settlement Agreements in four equal annual installments is the most viable option and, as of March 31, 2026, it classified the first $479 million installment as a current liability and the remaining $1.44 billion as a noncurrent liability on HEI’s and the Utilities’ Condensed Consolidated Balance Sheets. The Utilities have recorded an additional $40 million in “Accounts receivable and unbilled revenues, net” and “Other accounts receivable, net” on HEI’s and the Utilities’ Condensed Consolidated Balance Sheets, respectively, as of March 31, 2026, based on the amounts expected to be remaining under the applicable insurance policies at the time of settlement payment.

The Settlement Agreements are intended to resolve all of the pending and potential tort-related legal claims related to the Maui windstorm and wildfires. The Class Settlement Agreement provides releases by class plaintiffs to the defendants, and among defendants, for acts and omissions relating to the Maui windstorm and wildfires. The Individual Settlement Agreement requires individual plaintiffs who elect to accept the settlement to sign individual releases. The Settlement Agreements also provide that $500 million of the total settlement payments will be reserved and made available to defendants to defray the cost to resolve any claims brought by plaintiffs who do not release claims as part of either Settlement Agreement. The Settlement

Agreements contain multiple conditions that were met in order for any payment from HEI and Hawaiian Electric to the settlement funds to become due.

Insurer litigation. Two primary subrogation actions were brought by various insurers covering almost all of the direct subrogation claims. On December 30, 2025, the court in both actions entered judgment in favor of the defendants, but certain of the plaintiff insurers appealed those rulings. All insurers have now dismissed with prejudice those appeals, concluding the subrogation litigation.

Litigation with opt outs. As of March 31, 2026, approximately 80 individual plaintiffs who had initially “opted out” of the Class Settlement Agreement have not signed individual agreements and releases to join the global settlement. The defendants are continuing in their efforts to resolve these claims through the $500 million holdback fund that is part of the global settlement.

The Company intends to vigorously defend itself in the litigation if a definitive settlement of all open litigation is ultimately not achieved. There is no assurance that the Company will be successful in the defense of the litigation. If additional liabilities were to be incurred, the loss could be material to the Company’s results of operations, financial position and cash flows and could result in violations of the financial covenants in the Company’s debt agreements. If any such losses were to be sufficiently high, the Company may not have liquidity or the ability to access liquidity at levels necessary to satisfy such losses. However, any possible loss in excess of the amount recorded cannot reasonably be estimated at this time.

Securities class action. On August 24, 2023, a putative securities class action was filed in the United States District Court for the Northern District of California claiming violations of the Securities Exchange Act of 1934 (the Exchange Act) and Rule 10b-5 promulgated thereunder against HEI and Hawaiian Electric and certain of HEI’s and Hawaiian Electric’s current and former officers, and Section 20(a) of the Exchange Act against certain current and former officers (the Securities Action). The lawsuit broadly alleged that the defendants made materially false and misleading statements or omissions regarding our wildfire prevention and safety protocols and related matters.

On November 5, 2025, the parties signed a binding term sheet to settle the Securities Action (the Securities Action Term Sheet) following negotiations facilitated by a mediator. On January 5, 2026, the parties executed a definitive stipulation of settlement (the Securities Action Stipulation of Settlement) that will provide for the complete resolution of the Securities Action in exchange for a payment by the Company of $47.8 million as part of the overall settlement described below. The settlement of the Securities Action is subject to the following remaining conditions: final court approval of the Securities Action settlement and dismissal of the case pursuant to a final order, and final court approval of the Derivative Actions settlement and dismissal of those actions. In connection with the settlement of the Securities Action, there will be no admission of liability by the Company or any defendants and the Company, the defendants, and related persons will receive a customary full release of all claims. On March 3, 2026, the United States District Court for the Northern District of California preliminarily approved the Securities Action Stipulation of Settlement. The court set a hearing date for August 13, 2026 for the final approval of the settlement.

In connection with the execution of the Securities Action Term Sheet, HEI accrued $47.8 million in the third quarter of 2025, and, recorded an insurance reimbursement receivable of an equivalent amount as the recovery of the agreed settlement payment under its directors and officers liability insurance policy is deemed probable. In the third quarter of 2025, HEI charged the accrued settlement to “Expenses-Other” in HEI and Subsidiaries’ Condensed Consolidated Statements of Income, which was offset by the probable insurance recovery. The accrued settlement and insurance receivable is included in “Wildfire related claims” and “Accounts receivable and unbilled revenues, net,” under current liabilities and current assets, respectively, in HEI and subsidiaries’ Condensed Consolidated Balance Sheets.

Shareholder derivative lawsuits. Two putative shareholder derivative actions were filed in the Circuit Court of the First Circuit, State of Hawaii on September 11, 2023 and on November 6, 2024. In addition, three putative shareholder derivative actions were filed in the United States District Court for the Northern District of California between December 26, 2023 and February 8, 2024, and two putative shareholder derivative actions were filed in the United States District Court for the District of Hawaii between April 8, 2024 and June 8, 2024. All of the lawsuits were purportedly brought by shareholders on behalf of nominal defendants HEI and Hawaiian Electric against certain current and former officers and directors of HEI and Hawaiian Electric. In all of the cases, the plaintiffs generally alleged state law breaches of fiduciary duty, abuse of control, corporate waste, unjust enrichment, gross mismanagement and aiding and abetting breaches of fiduciary duty claims in connection with the Maui windstorm and wildfires and certain of the Company’s prior public disclosures, and some of them added claims based on purported violations of federal securities laws. Depending on the case, the plaintiffs were seeking, on behalf of HEI, damages, restitution, disgorgement, injunctive relief, and equitable relief, including in the form of changes to HEI’s corporate governance policies and procedures.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

On November 5, 2025, the parties signed a binding term sheet (the Derivative Litigation Term Sheet) to settle all of the outstanding derivative actions described above (the Derivative Actions). The Derivative Litigation Term Sheet was signed following negotiations facilitated by a mediator. On December 31, 2025, the parties executed a definitive settlement agreement (the Derivative Litigation Settlement Agreement) that provides for a complete resolution of the claims asserted in the Derivative Actions in exchange for a payment on behalf of the individual defendants by the Company’s insurers in the amount of $100 million, which will be used in part to pay the $47.8 million for the Securities Action Stipulation of Settlement and fees and expenses for plaintiffs’ counsel. The settlement of the Derivative Actions is subject to two remaining conditions: final court approval of the Derivative Litigation Settlement Agreement and final orders of dismissal of the Derivative Actions. The plaintiffs’ counsel intends to request court approval for attorneys’ fees of 25% of the settlement proceeds, plus expenses not to exceed $475,000. In connection with the settlement of the Derivative Actions, there will be no admissions of liability, and the defendants and related persons will receive a customary full release of all claims. The Securities Action Stipulation of Settlement and Derivative Litigation Settlement Agreement were promptly submitted to the courts for preliminary approval subsequent to execution. On March 9, 2026, the United States District Court for the District of Hawaii preliminarily approved the Derivative Litigation Settlement Agreement. The court set a hearing date for May 28, 2026 for the final approval of the Derivative Litigation Settlement Agreement.

The Derivative Litigation Settlement Agreement calls for the settlement to be fully funded by the Company’s directors and officers liability insurance policies. As noted above, $47.8 million of the $100 million total will be used to fund the settlement of the Securities Action. The remaining amount, any award in the Derivative Actions for the plaintiffs’ attorneys’ fees and expenses, and payment of other settlement-related expenses provided for in the term sheet, is accounted for as a contingent gain which will be recognized when realized or realizable.

Maui windstorm and wildfires costs. Legal costs in connection with the litigation and loss contingencies are expensed as incurred. The Company has $165 million of excess liability insurance and $25 million of professional liability insurance for third party claims, including claims related to wildfires, with a retention of $0.3 million and $1.0 million, respectively, and $145 million directors and officers liability insurance to cover claims related to the shareholder and derivative lawsuits, with a retention of $1.0 million. As of March 31, 2026, the Company’s and Utilities’ insurance receivable totaled $93 million and $45 million, respectively, under the policies. As of March 31, 2026, HEI and its subsidiaries have approximately $9 million, nil and $70 million of insurance coverage remaining under the excess liability, professional liability, and directors and officers liability policies, respectively, after deducting applicable retention amounts, amounts that have been recovered under insurance policies (including the One ‘Ohana Initiative contribution), and amounts expected to be recovered for incurred costs and recognized as a receivable as of March 31, 2026.

Subsequent event. On April 10, 2026, the final condition to payment occurred under the Settlement Agreements. The final condition was that the judgment that HEI and Hawaiian Electric obtained on December 30, 2025, on the subrogation claims brought by over 200 insurers, became final and unappealable after all insurers stipulated to dismiss with prejudice their appeals of that judgment. Accordingly, pursuant to the Settlement Agreements, on April 10, 2026, HEI and Hawaiian Electric paid the first of four equal annual $479 million installments. The funds for this first $479 million payment were previously raised by HEI’s September 2024 equity offering and had been held in a special purpose vehicle formed specifically to hold this first payment, pending the resolution of all conditions to payment, which have now been met. With all conditions to payment met,

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

the releases in the Settlement Agreements and those signed by individual claimants are now effective. HEI and Hawaiian Electric will seek insurance recovery based on the remaining coverage on the excess liability insurance to partially mitigate the financial impact.

The future installments are due in April 2027, April 2028 and April 2029. With the releases now effective, the parties to the litigation are now in the process of dismissing the thousands of lawsuits.

Note 3 · Segment financial information

Reportable segments are strategic business units of the Company that offer different products and services and operate in different regulatory environments.

Sales from Hamakua Energy, LLC (Hamakua Energy) to Hawaii Electric Light (a regulated affiliate), up until the close of its sale on March 10, 2025, are eliminated in consolidation.

ASB Hawaii. ASB Hawaii was formed in 1988 and served as the holding company for ASB prior to its sale on December 31, 2024. ASB Hawaii still retains a 9.9% noncontrolling investment in ASB.

GLST1. GLST1 was formed in November 2024 for the purpose of holding the first installment payment pursuant to the settlement of the Maui windstorm and wildfire tort-related legal claims. HEI transferred the amount of the first settlement payment, $479 million, into GLST1, which is restricted from disbursing such funds except in connection with the initial payment to the settlement funds and is classified as “Restricted cash” on the Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025. Effective March 31, 2025, HEI assigned 60% of the membership interests of GLST1 to Hawaiian Electric. As of March 31, 2026, the assigned equity interests total $287.3 million, which is reported on “Investment in unconsolidated affiliate” on the Utilities’ Condensed Consolidated Balance Sheets. See “Subsequent event” in Note 2.

Pacific Current. Pacific Current was formed in 2017 to focus on investing in non-regulated renewable energy and sustainable infrastructure in the State of Hawaii to help achieve the state’s sustainability goals. As part of HEI’s comprehensive review of strategic options for Pacific Current, significant investments of Pacific Current that were made through its subsidiaries,

Hamakua Energy, Mauo and Kaʻieʻie Waho were sold in 2025. Mahipapa is Pacific Current’s remaining operating subsidiary, which owns a 7.5-MW renewable, firm dispatchable closed-loop biomass-to-energy facility on Kauai that provides electricity to Kauai Island Utility Cooperative under a PPA that expires in January 2036.

Assets held for sale-Mahipapa. In addition, in connection with the Solar Asset Disposition and as part of the membership interest purchase agreement pursuant to which the Solar Asset Disposition was conducted (MIPA), but as a separate transaction, Pacific Current agreed to sell all of the membership interest in its biomass subsidiary, Mahipapa, LLC, to the same unaffiliated third party that is party to the MIPA (the Mahipapa Sale), with each of the parties’ obligations to complete the Mahipapa Sale subject to the conditions set forth in the MIPA. The net assets and liabilities of Mahipapa are classified as held for sale in the Company’s Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025.

Note 4 · Electric utility segment

Consolidated variable interest entities. The HE AR INTER LLC and its direct subsidiary, HE AR BRWR LLC, (collectively, the Special Purpose Entities or SPEs) are bankruptcy remote, direct and indirect wholly owned subsidiaries of the Utilities. Pursuant to the asset-based lending facility (ABL Facility) credit agreement, the Utilities sell certain accounts receivable to the SPEs as collateral, which in turn, obtain financing from financial institutions. As of March 31, 2026, the ABL Facility remains undrawn and the SPEs have $317.0 million of net accounts receivable, included in “Customer accounts receivable, net,” and “Accrued unbilled revenues, net” on the Utilities’ Condensed Consolidated Balance Sheets and “Accounts receivable and unbilled revenues, net” on the Company’s Condensed Consolidated Balance Sheets.

The SPEs are considered VIEs due to insufficient equity investment at risk. The most significant activities that impact the economic performance of the SPEs are cash and financing management. The Utilities are considered the primary beneficiary as the Utilities direct the activities related to cash and financing management and therefore, are required to consolidate the SPEs. Although the SPEs are direct and indirect wholly owned consolidated subsidiaries of the Utilities, the SPEs are legally separate from the Utilities. The assets of the SPEs (which are primarily accounts receivables) are not available to creditors of the Utilities.

Unconsolidated variable interest entities.

Power purchase agreements. The Utilities have power purchase agreements (PPAs) with independent power producers (IPPs) and Schedule Q providers (i.e., customers with cogeneration and/or power production facilities who buy power from or sell power to the Utilities). As of March 31, 2026, the Utilities evaluated and concluded none of the IPPs or Schedule Q providers are currently required to be consolidated by reasons that i) no variable interests exist in the PPAs; ii) where variable interests are present, the Utilities are not deemed the primary beneficiary due to lack of power to direct the activities that most significantly impact the IPPs’ economic performance; or iii) the PPAs qualify for scope exceptions under current accounting standards for consolidation.

The carrying amounts of assets and liabilities related to the Utilities’ PPAs, where variable interests are present but the Utilities are not deemed the primary beneficiary, are limited to the purchased power and energy payments. As the Utilities recover such payments through the PUC-approved Purchased Power Adjustment Clause (PPAC) or the Energy Cost Recovery Clause (ECRC) mechanism, there is no significant potential exposure to loss to the Utilities as of March 31, 2026.

GLST1. GLST1 was formed in November 2024 for the purpose of holding the first installment payment pursuant to the settlement of the Maui windstorm and wildfire tort-related legal claims. Effective March 31, 2025, HEI assigned 60% of the membership interests of GLST1 to Hawaiian Electric. The Utilities are deemed to have a variable interest in GLST1 but concluded that the Utilities are not the primary beneficiary of GLST1. As the Utilities have the ability to exercise significant influence over GLST1, the Utilities accounted for the membership interests under the equity method of accounting. As of March 31, 2026, the assigned equity interests total $287.3 million, which is reported on “Investment in unconsolidated affiliate” on the Utilities’ Condensed Consolidated Balance Sheets. See “Subsequent event” in Note 2.

Commitments and contingencies.

Contingencies. The Utilities are subject in the normal course of business to legal, regulatory and environmental proceedings. Excluding the liabilities from the Maui windstorm and wildfires, management does not anticipate that the aggregate ultimate liability arising out of these pending or threatened legal proceedings will be material to its financial position. However, the Utilities cannot rule out the possibility that such outcomes could have a material effect on the results of operations or liquidity for a particular reporting period in the future.

August 2023 Maui windstorm and wildfires. See Note 2.

Property insurer litigation. On February 13, 2026, Hawaiian Electric Industries, Inc., Hawaiian Electric Company, Inc., and Maui Electric Company, Limited (collectively, the Hawaiian Electric Plaintiffs) filed suit against five of their insurers: Defendants XL Insurance Company of America, Inc., Allianz Global Risks US Insurance Company, the Princeton Excess and Surplus Lines Insurance Company, and General Security Indemnity Company of Arizona (collectively, the HEI Insurers). The HEI Insurers are commercial property insurers that insured the Hawaiian Electric Plaintiffs at the time of the August 2023 Maui windstorm and wildfires. The Hawaiian Electric Plaintiffs also had commercial property insurance under policies issued by Associated Electric & Gas Insurance Services (AEGIS), Ascot Syndicate 1414, IQUW Syndicate 1856, Energy Insurance Mutual, QBE International Markets, and Certain Underwriters at Lloyd’s London and Insurers (collectively, the AEGIS Insurers). Under the policies with the AEGIS Insurers, the Hawaiian Electric Plaintiffs and the AEGIS Insurers are required to engage in negotiations meetings, and if negotiation is unsuccessful, mediation. Accordingly, the Hawaiian Electric Plaintiffs did not name the AEGIS Insurers as defendants in the complaint filed on February 13, 2026.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

The HEI Insurers and AEGIS Insurers (jointly, the Property Insurers) have acknowledged coverage under the policies at issue for loss or damage to the Hawaiian Electric Plaintiffs’ property and have paid a portion of the Hawaiian Electric Plaintiffs’ losses. However, the parties dispute the extent of the damage, the nature of coverage, and apportionment under the policies. Therefore, the Hawaiian Electric Plaintiffs seek declaratory relief regarding the extent of the Property Insurers’ obligations under the policies, as well as a determination that the Property Insurers have breached the policies. In April 2026, the Hawaiian Electric Plaintiffs and the Property Insurers engaged in negotiations and expect to finalize a settlement in the second quarter of 2026. The settlement would resolve all disputes with the AEGIS Insurers with respect to coverage, and a portion of the disputes between the Hawaiian Electric Plaintiffs and the HEI Insurers. Litigation will proceed in federal district court with respect to the remaining disputed insurance claims against the HEI Insurers not covered by the settlement. Mediation between the Hawaiian Electric Plaintiffs and the HEI Insurers is scheduled for July 8, 2026.

Hu Honua Bioenergy, LLC (Hu Honua). In 2013, Hu Honua filed a lawsuit in the U.S. District Court for the District of Hawaii based on Hawaii Electric Light’s termination of a PPA between the parties. The lawsuit asserted breach of contract and antitrust claims. On April 17, 2025, the U.S. District Court granted Hawaii Electric Light’s Motion to Dismiss in part, dismissing the Federal Antitrust claims, but declining to exercise jurisdiction over the State antitrust claim. The remaining State claims, including the contract claims and the State antitrust claim, were dismissed without prejudice.

On May 14, 2025, Hu Honua filed its notice of appeal in federal Ninth Circuit court. Due to ongoing negotiations between Hu Honua and Hawaii Electric Light on a new PPA, the appellate briefing schedule has been vacated, and the court issued an administrative closure until May 15, 2026, by which time Hu Honua must provide a status report to the court. The court noted that at any time before that date, any party may request that the appeal be reopened.

On May 16, 2025, Hu Honua filed its complaint in state court for the remaining State claims. Hu Honua has granted Hawaii Electric Light an open-ended extension to answer or otherwise respond to the State complaint while PPA negotiations are ongoing. The State court ordered a scheduling conference for August 12, 2025, which was subsequently postponed to July 7, 2026, to allow the parties to continue ongoing settlement discussions.

Molokai New Energy Partners (MNEP). In July 2018, the PUC approved Maui Electric’s PPA with MNEP to purchase solar energy from a photovoltaic (PV) plus battery storage project. The 4.88-MW PV and 3-MW Battery Energy Storage System (BESS) project was to deliver no more than 2.64 MW at any time to the Molokai system. On March 25, 2020, MNEP filed a complaint in the U.S. District Court for the District of Hawaii against Maui Electric claiming breach of contract. On June 3, 2020, Maui Electric provided a Notice of Default and Termination of the PPA to MNEP terminating the PPA with an effective date of July 10, 2020. Thereafter, MNEP filed an amended complaint to include claims relating to the termination and Hawaiian Electric filed its answer to the amended complaint on September 11, 2020, disputing the facts presented by MNEP and all claims within the original and amended complaint. Currently, the discovery phase is ongoing. Trial which was previously set to commence on September 16, 2025 was continued to February 18, 2026 and is now set to begin November 13, 2026.

Environmental regulation. The Utilities are subject to environmental laws and regulations that regulate the operation of existing facilities, the construction and operation of new facilities and the proper cleanup and disposal of hazardous waste and toxic substances.

Hawaiian Electric, Hawaii Electric Light and Maui Electric, like other utilities, periodically encounter petroleum or other chemical releases associated with current or previous operations. The Utilities report and take action on these releases when and as required by applicable law and regulations. The Utilities believe the costs of responding to such releases identified to date will not have a material effect, individually or in the aggregate, on Hawaiian Electric’s consolidated results of operations, financial condition or liquidity.

Former Molokai Electric Company generation site. In 1989, Maui Electric acquired Molokai Electric Company. Molokai Electric Company had sold its former generation site (Site) in 1983 but continued to operate at the Site under a lease until 1985 and left the property in 1987. The Environmental Protection Agency (EPA) has since identified environmental impacts in the subsurface soil at the Site. In cooperation with the State of Hawaii Department of Health and EPA, Maui Electric further investigated the Site and the adjacent parcel to determine the extent of impacts of polychlorinated biphenyls (PCBs), residual fuel oils and other subsurface contaminants. Maui Electric has a reserve balance of $2.4 million as of March 31, 2026, representing the probable and reasonably estimable undiscounted cost for remediation of the Site and the adjacent parcel based on presently available information; however, final costs of remediation will depend on the cleanup approach implemented.

Pearl Harbor sediment study. In July 2014, the U.S. Navy notified Hawaiian Electric of the Navy’s determination that Hawaiian Electric is a Potentially Responsible Party under CERCLA responsible for the costs of investigation and cleanup of PCB contamination in sediment in the area offshore of the Waiau power plant as part of the Pearl Harbor Superfund Site.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

Hawaiian Electric was also required by the EPA to assess potential sources and extent of PCB contamination onshore at Waiau power plant.

As of March 31, 2026, the reserve account balance recorded by Hawaiian Electric to address the PCB contamination was $9.5 million. The reserve balance represents the probable and reasonably estimable undiscounted cost for the onshore and offshore investigation and remediation. The final remediation costs will depend on the actual onshore and offshore cleanup costs.

Endangered Species Act. The Utilities received a notice under the federal Endangered Species Act, from Earthjustice on behalf of the American Bird Conservancy and Conservation Council for Hawaii (Conservation Groups) in January 2024. The notice is the pre-cursor to a citizen’s suit under the Endangered Species Act. The notice alleges that the Utilities are out of compliance with the Act due to alleged impacts on endangered seabirds caused by the Utilities’ powerlines, street lights and facility lights on Maui and Lanai. At the time the notice was served, the Utilities were already in the process of drafting a Habitat Conservation Plan (HCP) with respect to the powerlines and will be applying for associated state and federal take/license permits. Notwithstanding, the notice asserts that the scope of the HCP should be broader and additional interim measures are necessary while the HCP and related permits are pending.

After negotiations among the parties a complaint was filed on November 12, 2024 regarding the powerlines and on December 11, 2024, the court approved a settlement agreement. Pursuant to that agreement, the Utilities will continue the HCP process and take specific actions to minimize and mitigate the potential impact of the Utilities’ powerlines while the document is being prepared. The agreement also contains additional requirements that include coordination with the Conservation Groups with various aspects of the HCP and powerline operations, and continuing the Utilities’ commitment to a species mitigation project with University of Hawaii Foundation to monitor, protect and increase the population of Hawaiian Petrels.

The street and facility lights aspect of the notice was not resolved and a second complaint was filed on November 19, 2024, that includes the County of Maui as a party. Hawaiian Electric and Maui Electric answered the complaint on December 12, 2024 and at this time, the parties have completed discovery. Summary judgment motions are pending, and a trial date is expected later in 2026. The parties may engage in additional settlement discussions in an effort to resolve the matter. However, the Utilities are unable to determine the ultimate outcome or the amount of any possible loss.

Commitments.

Purchase commitments. As of December 31, 2025, the Utilities’ estimated future minimum payments pursuant to purchase obligations related to material contracts of $2.63 billion. See Note 4 of the Notes to the Consolidated Financial Statements in Item 8 of the 2025 Form 10-K.

As of March 31, 2026, a total of nine Stage 1 and Stage 2 renewable projects provide the Utilities a capacity of 301.5 MW, with 1,771-MWh batteries.

Utility projects. Many public utility projects require PUC approval and various permits from other governmental agencies. Difficulties in obtaining, or the inability to obtain, the necessary approvals or permits or community support can result in significantly increased project costs or even cancellation of projects. In the event a project does not proceed, or if it becomes probable the PUC will disallow cost recovery for all or part of a project, or if PUC-imposed caps on project costs are expected to be exceeded, project costs may need to be written off in amounts that could result in significant reductions in Hawaiian Electric’s consolidated net income.

Waena battery energy storage system project. In September 2020, Maui Electric filed a PUC application to purchase and install a 40-MW BESS at its Waena Site in Central Maui. In December 2023, the PUC approved Maui Electric’s request to commit funds estimated at $82.1 million, for the purchase and installation of the project, and to recover costs for the project under Exceptional Project Recovery Mechanism (EPRM). In July 2025, the PUC approved the Utilities’ request to authorize recovery of costs in addition to the amounts approved in December 2023 due to the uncertainty of changes in law, limited to the lesser of either the actual costs or 20% over the approved estimated capital costs. Project costs incurred as of March 31, 2026, amount to $23.6 million.

Climate adaptation transmission and distribution resilience program. The Utilities maintain that improving resiliency of the electric grid is an urgent matter and recognizes that evolving climate dynamics are making Hawaii increasingly vulnerable to severe weather events. On January 31, 2024, the PUC approved the Utilities’ request to commit an estimated $189.7 million in funds for the climate adaptation transmission and distribution resilience program, over a project period of five years. The project will focus on, among other things, system hardening in wildfire risk areas including installing video camera and weather monitors in wildfire risk areas and strengthening transmission lines to help prevent ignition, enable quicker response and add situational awareness.

The project costs to be recovered through EPRM is subject to a cap of $95 million and any amount in excess will be subject to the PUC’s further review. On August 7, 2024, the Utilities received a notification from the U.S. Department of Energy that their application for $95 million in federal funds under the Infrastructure Investment and Jobs Act was officially awarded. On August 20, 2024, the Utilities submitted a copy of their executed agreement with the Department of Energy to the PUC. On November 18, 2024, the Utilities filed their August 2024 - August 2025 Forward Looking Annual Report. Project costs incurred as of March 31, 2026, amount to $41.7 million.

In 2025, President Trump issued multiple executive orders that impact federal funding. The Utilities are not impacted at this time but will continue to monitor for any new executive orders and any changes that are passed down through the federal contracting officer for the resilience program.

Waiau repower project. On March 28, 2025, the Utilities filed an application to the PUC for their self-build project - Waiau repower project. The project, selected as part of a competitive bid process, was estimated at $847 million and involves replacing six existing turbines with six fuel-flexible combustion turbines that provide 253 MW of renewable firm generation, expected to be placed in service in stages from 2029 to 2033. The Utilities requested, among other things, approvals of 1) the commitment of funds for such project, and 2) recovery of project costs through the EPRM. On October 17, 2025, the Utilities filed an updated application reflecting revised costs of $1.16 billion, citing unavoidable and changed market conditions outside the Utilities’ control. On March 23, 2026, the PUC approved the commitment of funds and EPRM recovery for the Waiau repower project at the initial estimated cost of $847 million plus the lesser of a 10% increase or the difference in the Gross Domestic Product Price Index (GDPPI) between the date of the best and final offer submission and the date of the PUC’s decision and order (Inflationary Adjustment). On April 2, 2026, the Utilities filed a motion for reconsideration of the PUC’s decision and order. On April 17, 2026, the PUC issued an order addressing the Utilities’ motion for reconsideration which, among other things, affirmed that the project costs up to $847 million plus the Inflationary Adjustment can be recovered through EPRM and clarified that the Utilities may, after the project is in-service, seek recovery for project cost amounts greater than the approved amount in a general rate case or rate re-basing proceeding. Based on the estimated GDPPI for the first quarter of 2026 released by the Bureau of Economic Analysis on April 30, 2026, the project costs plus the Inflationary Adjustment are currently estimated at $908 million.

On April 28, 2026, in connection with the Waiau repower project, Hawaiian Electric entered into three contracts to acquire a total of six gas turbine units from GE Vernova Operations, LLC to secure the manufacturing and staggered delivery of gas turbine units in pairs between 2029 and 2030. These contracts mitigate the risk of delayed turbine unit deliveries, remove the exposure to non-tariff price increases, and support the achievement of on-time commercial operations of the Waiau repower project.

In December 2025, Federal Emergency Management Agency issued a Letter of Final Determination on the preliminary updates to Oahu’s Flood Insurance Rate Maps. As a result of the updates, portions of the Waiau power plant will transition to a newly designated flood zone A, which is estimated to have a 1% chance of annual flooding. The new flood maps will become effective on June 10, 2026. The Utilities are currently assessing the impact the change may have on the Waiau repower project.

Regulatory proceedings.

Performance-based regulation framework (PBR Framework). The PUC issued a decision and order (PBR D&O) establishing the PBR Framework to govern the Utilities. The PBR Framework implemented a five-year multi-year rate period (MRP), during which there will be no general rate case applications. The current MRP will end on May 31, 2026, and the next MRP (MRP2) is currently scheduled to commence on January 1, 2027. The period in between the end of the current MRP and

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

the beginning of MRP2 is intended to be a transition period (see Phase 7 discussed below). PBR working group meetings were held in 2024, 2025, and early 2026 to consider potential PBR changes for MRP2. The PBR Framework Review will continue with the following: (i) Phase 6: consideration and development of proposals for modifications to the PBR Framework, which focuses on inflation factor, customer dividend, Earnings Sharing Mechanism (ESM), revenue opportunities afforded by the X-Factor and the EPRM guidelines, and Performance Incentive Mechanisms (PIMs) portfolio, and (ii) Phase 7: the finalization and documentation of approved PBR Framework modifications prior to MRP2 commencement.

Alternative re-basing. In its order issued on February 27, 2025, the PUC concluded that the Utilities’ target revenues should be re-based for MRP2 and allowed the Utilities to file a single, consolidated application that presents their requested adjustment to target revenues. The proceeding to re-base the Utilities’ target revenues for MRP2 shall be bifurcated into two tracks, with the first track focused on reaching a decision on the Utilities’ revenue requirements prior to the commencement of MRP2, and the second track focused on making a final determination on the revenue requirement and addressing the rate design component. On March 6, 2026, the Utilities filed a joint alternative re-basing proposal with Ulupono Initiative, requesting an increase of $170 million over annual target revenues at current effective rates, with $125 million phased into revenues in the first year of MRP2 and the remaining $45 million implemented in the second year of MRP2. The Utilities are awaiting PUC guidance on the procedural process to review the joint alternative re-basing proposal.

Earnings Sharing Mechanism. The PBR Framework established a symmetrical ESM for achieved rate-making return on average common equity (ROACE) outside of a 300 basis points deadband above or below the current authorized ROACE of 9.5% for each of the Utilities (i.e., above 12.5% or below 6.5%). There is a 50/50 sharing between customers and Utilities for the achieved rate-making ROACE falling within 150 basis points outside of the deadband in either direction, and a 90/10 sharing for any further difference. A reopening or review of the PBR terms may be triggered if the Utilities’ credit rating outlook indicates a potential credit downgrade below investment grade status, or if its achieved rate-making ROACE enters the outer most tier of the ESM.

On August 31, 2023, the PUC issued an order temporarily suspending the ESM until further notice. The intent of the order is to address the unintended consequence of customers potentially bearing the costs associated with the Maui windstorm and wildfires through the operation of the ESM without prior PUC review.

Exceptional Project Recovery Mechanism. The established EPRM Guidelines, formerly known as Major Project Interim Recovery (MPIR), permit the Utilities to include the full amount of approved costs in the EPRM for recovery in the first year the project goes into service, pro-rated for the portion of the year the project is in service. Deferred and other operation and maintenance (O&M) expense projects are also eligible for EPRM recovery under the EPRM Guidelines. EPRM recoverable costs are limited to the lesser of actual incurred project costs or the PUC‑approved amounts, net of savings. The recovery of the project costs previously approved under the MPIR continues within the PBR Framework.

As of March 31, 2026, the Utilities’ annualized MPIR and EPRM revenue amounts totaled $39.3 million, including revenue taxes. The annualized MPIR and EPRM revenues are subject to PUC approval and recovery would be effective June 1, 2026 through the Revenue Balancing Account (RBA) rate adjustment.

As of March 31, 2026, the PUC approved the recovery of five EPRM projects with an estimated amount of $1.14 billion in capital costs to the extent the project costs are not included in rates. Currently, the Utilities are seeking EPRM recovery for two additional projects subject to PUC approval.

Performance Incentive Mechanisms. On December 18, 2024, and clarified on January 15, 2025, the PUC issued orders granting the Utilities’ request to suspend the Transmission and Distribution (T&D) System Average Interruption Duration Index (SAIDI) and T&D System Average Interruption Frequency Index (SAIFI) PIMs for wildfire risk circuits from January 1, 2024 to December 31, 2025. Separately, the Utilities submitted a request on December 16, 2025 to expand the suspension of T&D SAIDI and T&D SAIFI PIMs (T&D PIMs) to all circuits and extend the suspension to December 31, 2026, to consider modifications to the T&D PIMs. On April 21, 2026, the PUC issued an order denying the Utilities’ request to expand suspension of T&D PIMs to all circuits, but, on its own motion, extended the current suspension of the T&D PIMs for wildfire risk circuits through December 31, 2026. Consistent with the current suspension, this shall include continued exclusion of all Public Safety Power Shutoff program events from PIM performance metrics and targets. The suspension may be further extended beyond 2026 based on the Utilities request and proposal justifying the same, required to be submitted no later than October 1, 2026. Absent PUC approval of any further extension, the T&D PIMs suspension will expire and no exclusions on any circuits will be valid after December 31, 2026.

For the 2025 evaluation period, the Utilities accrued $7.5 million (nil for Hawaiian Electric, $5.4 million for Hawaii Electric Light and $2.1 million for Maui Electric) in rewards net of penalties. The net rewards related to 2025 were reflected in the 2026 PIMs annual report and 2026 spring revenue report filings with the exception of the Phase 1 RFP PIM, which was reflected in the 2025 fall revenue report filing.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

Annual review cycle. Under the PBR Framework, target revenues are adjusted according to an index-driven annual revenue adjustment (ARA) based on: (i) an inflation factor, (ii) a predetermined X-factor to encompass productivity, which is set at zero, (iii) a Z-factor to account for exceptional circumstances not in the Utilities’ control and (iv) a customer dividend consisting of a negative adjustment of 0.22% of adjusted revenue requirements compounded annually and a flow through of the “pre-PBR” savings commitment from the management audit recommendations developed in a prior docket at a rate of $6.6 million per year from 2021 until the rate resets.

PBR D&O also established an annual review cycle for revenue adjustments under the PBR Framework, including the biannual submission of the revenue reports. The Utilities filed the 2026 spring revenue report on March 31, 2026, which is subject to PUC approval. The filing reflected ARA revenues for the third year recovery of the COVID-19 related deferred costs through the Z-factor and the accelerated return of the Enterprise Resource Planning system benefits savings to Hawaii Electric Light and Maui Electric customers as part of the customer dividend, as follows:

Regulatory assets and liabilities.

Regulatory assets for Maui windstorm and wildfires related costs. The PUC has issued orders authorizing deferred accounting treatment for certain incremental non-labor expenses related to the Maui windstorm and wildfires incurred from August 8, 2023 through December 31, 2025. The approval pertains only to deferred cost treatment for expenses that are not already part of base rates; any actual recovery of deferred costs will be the subject of a separate application(s).

As of March 31, 2026, the Utilities have recorded $80.5 million in regulatory assets for the incremental costs incurred during the aforementioned period related to the Maui windstorm and wildfires event.

Requests for cost recovery of deferred costs will be the subject of a separate application at which time the PUC will evaluate whether such costs were prudently incurred and reasonable and determine the extent to which such costs will be eligible for recovery, and the period over which recovery will occur. If the PUC denies recovery of any deferred costs, such costs would be charged to expense in the period that those costs are no longer considered probable of recovery.

Regulatory assets for Wildfire Mitigation Plan (WMP). On December 31, 2025, the PUC approved the Utilities’ 2025-2027 WMP (also referred to as Wildfire Safety Strategy or WSS). The Utilities’ 2025-2027 WMP is a three-year action plan that targets a material reduction in wildfire risk associated with utility infrastructure. The PUC also directed the Utilities to provide a WMP update bi-annually. The approval of the 2025-2027 WMP, however, does not constitute approval of cost recovery for any WMP-related costs. The Utilities’ request for cost recovery is currently under review by the PUC in a separate proceeding. As of March 31, 2026, the Utilities have recorded a regulatory asset of $12.6 million. Recovery of the Utilities’ O&M expenses are currently under PUC review in the EPRM cost recovery proceeding.

Regulatory assets for suspension of disconnections related costs. Based on circumstances related to the Maui windstorm and wildfires, on August 31, 2023 and subsequently on October 13, 2023, the PUC issued orders directing all regulated utilities

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

located on, or providing utility service on Maui, among other things, (i) to suspend disconnections of services and associated disconnection fees beginning from August 8, 2023, through the end of the emergency relief period established by the Governor’s Emergency Proclamations related to the Maui windstorm and wildfires, which currently continues through July 4, 2026 (Suspension Period); (ii) to suspend any and all rules and provisions of individual utility tariffs that prevent or condition re-connection of disconnected customers during the Suspension Period; (iii) not to charge customers interest on past due payments or impose any late payment fees through the Suspension Period; (iv) to establish regulatory assets to record costs directly related to the suspension of disconnections, and to record receipt of governmental aid and donation-based aid, loans or grants, and/or all other assistance measures, and any cost savings realized; and (v) to file a notice with the PUC regarding any upcoming application or other request pursuant to Hawaii Revised Statues Sections 269-16.3, -17, -17.5, -18, -19, or -19.5 and/or regarding any significant financial change to the Maui utility, at least 60 days prior to filing such application or other request with the PUC. The orders also discourage the filing of emergency or general rate increases in response to the emergency situation. On December 23, 2025, the PUC revised the notice of financial change reporting requirement (item v above) to apply only to the Utilities.

In future proceedings, the PUC will assess the utility’s request for recovery of these regulatory assets including whether it is reasonable and necessary, the appropriate period of recovery for the approved amount of regulatory assets, any amount of carrying costs thereon, any savings directly attributable to suspension of disconnects, and other related matters. As of March 31, 2026, the Utilities have recorded $6.2 million in regulatory assets for the incremental costs incurred due to the suspension of disconnections.

Syndicated credit agreements. On September 5, 2025, HEI and Hawaiian Electric each entered into a fourth amended and restated senior unsecured revolving credit facility (the HEI Facility and the Hawaiian Electric Facility, respectively) with a syndicate of eight financial institutions. The aggregate amount of revolving commitments under the HEI Facility was increased to $300 million from $175 million and includes a $25 million letter of credit sub-facility and a $30 million swingline sub-facility. The HEI Facility’s commitment termination date was extended to September 5, 2030 from May 14, 2027. The aggregate amount of revolving commitments available under the Hawaiian Electric Facility was increased to $300 million from $200 million and includes a $40 million letter of credit sub-facility and a $30 million swingline sub-facility. The Hawaiian Electric Facility’s term was extended to September 4, 2026, subject to an automatic extension to the earlier of (i) such date specified in a final order or approval of the PUC and (ii) if such order or approval is obtained, September 5, 2030. The Hawaiian Electric Facility also allows for commitment increases of up to an additional $75 million, subject to customary conditions. None of the facilities are collateralized. As of March 31, 2026, HEI and Hawaiian Electric had $15 million and nil drawn on their revolving facilities, respectively.

Intercompany borrowing agreement. Under the HEI and Hawaiian Electric Intercompany Borrowing and Investment Policy effective January 1, 2020 (the Intercompany Borrowing Policy), HEI has committed to make revolving short-term loans to Hawaiian Electric pursuant to the terms set forth in the standing commitment letter dated December 5, 2025 (the 2025 Commitment Letter). For loans that mature on or before December 4, 2026, the 2025 Commitment Letter provides a borrowing limit of $75 million outstanding at any time and the applicable interest rate. Hawaiian Electric currently has no borrowings under the Intercompany Borrowing Policy and the 2025 Commitment Letter.

Asset-based lending facility credit agreement. On May 17, 2024, Hawaiian Electric, through a special-purpose subsidiary, entered into an ABL Facility credit agreement (ABL Credit Facility Agreement) with several banks, which, subject to the limitations and conditions set forth in such agreement, allows borrowings of up to $250 million on a revolving basis using certain accounts receivable as collateral. The ABL Facility was approved by the PUC, became effective on July 24, 2024 and will expire on July 24, 2027. As of March 31, 2026, total available capacity under the ABL Facility was $218 million and remains undrawn.

HEI consolidated recorded retirement benefits expense of $11 million ($11 million by the Utilities) in each of the first three months of 2026 and 2025, and charged the remaining net periodic benefit cost primarily to electric utility plant.

The Utilities have implemented pension and OPEB tracking mechanisms under which all of their retirement benefit expenses (except for executive life and nonqualified pension plan expenses) determined in accordance with GAAP are recovered over time. Under the tracking mechanisms, any actual costs determined in accordance with GAAP that are over/under amounts allowed in rates are charged/credited to a regulatory asset/liability. The regulatory asset/liability for each utility will then be amortized over five years beginning with the respective utility’s next rate case.

Defined contribution plans information. For the first three months of 2026 and 2025, the Company’s expenses and cash contributions for its defined contribution plans under the Hawaiian Electric Industries Retirement Savings Plan were $2.4 million and $1.8 million, respectively. For the first three months of 2026 and 2025, the Utilities’ expenses and cash contributions for its defined contribution plan under the Hawaiian Electric Industries Retirement Savings Plan were $2.3 million and $1.7 million, respectively.

Note 9 · Share-based compensation

Under the 2010 Equity and Incentive Plan, as amended and restated effective February 9, 2024 (EIP), HEI can issue shares of common stock as incentive compensation to nonemployee directors and selected employees and consultants in the form of stock options, stock appreciation rights, restricted shares, restricted stock units, performance shares and other share-based and cash-based awards.

As of March 31, 2026, approximately 2.5 million shares remained available for future issuance under the terms of the EIP, assuming recycling of shares withheld to satisfy statutory tax liabilities relating to EIP awards, including an estimated 1.6 million shares that could be issued upon the vesting of outstanding restricted stock units and the achievement of performance goals for awards outstanding under long-term incentive plans (assuming that such performance goals are achieved at maximum levels).

Under the 2011 Nonemployee Director Stock Plan (2011 Director Plan), HEI can issue shares of common stock as compensation to nonemployee directors of HEI and its principal subsidiaries. As of March 31, 2026, there were 41,964 shares remaining available for future issuance under the 2011 Director Plan. After all of the shares remaining under the 2011 Director Plan have been issued or reserved for issuance, nonemployee director grants of common stock will be made under the EIP, which was amended in 2024 to provide for nonemployee director grants.

Share-based compensation expense and the related income tax benefit were as follows:

For the three months ended March 31, 2026 and 2025, total restricted stock units and related dividends that vested had a fair value of $0.4 million and $0.5 million, respectively, and the related tax benefits were nil and $0.1 million, respectively.

As of March 31, 2026, there was no unrecognized compensation cost related to restricted stock units.

Long-term incentive plan payable in stock. The 2024-26, 2025-27 and 2026-28 long-term incentive plans (LTIP) provide for performance awards under the EIP of shares of HEI common stock based on the satisfaction of performance goals. The number of shares of HEI common stock that may be awarded is fixed on the date the grants are made, subject to the achievement of specified performance levels and calculated dividend equivalents. The potential payout varies from 0% to 220% of the number of target shares, depending on the achievement of the goals. The 2024-26 LTIP performance goals include a market condition goal. The market condition goal is based on HEI’s total shareholder return (TSR) compared to the Peer Group (the Company’s compensation peer group consisting of companies in the EEI Index and approved by the Company’s Compensation & Human Capital Management Committee), in each case over the relevant three-year period. The

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Unaudited) continued

other performance condition goals relate to Hawaiian Electric’s credit rating, public safety, funds from operations to total adjusted debt ratio and customer experience. The 2025-27 and 2026-28 LTIPs include other performance goals (described above) and a relative TSR payout modifier, which may adjust the payout shares based on the relative TSR result. The relative TSR modifier is based on HEI’s TSR compared to the Peer Group.

LTIP linked to TSR. Information about HEI’s LTIP grants linked to TSR was as follows:


	Three months ended March 31
		2026	2025
			Shares		(1)		Shares		(1)

Total weighted-average grant-date fair value of shares granted (in millions)			$	5.4			$	5.2

(1) Weighted-average grant-date fair value per share determined using a Monte Carlo simulation model.

The grant date fair values of the LTIP awards linked to TSR were determined using a Monte Carlo simulation model utilizing actual information for the common shares of HEI and the Peer Group for the period from the beginning of the performance period to the grant date and estimated future stock volatility of HEI and the Peer Group over the remaining three-year performance period. The expected stock volatility assumptions for HEI and the Peer Group were based on the three-year historic stock volatility. A dividend assumption is not required for the Monte Carlo simulation because the grant payout includes dividend equivalents and projected returns include the value of reinvested dividends.

The following table summarizes the assumptions used to determine the fair value of the LTIP awards linked to TSR and the resulting fair value of LTIP awards granted:


	2026			2025
Risk-free interest rate	3.49		%	4.37		%
Expected life in years	3			3
Expected volatility	65.3		%	64.7		%

Grant-date fair value (per share) (HEI)	$	17.04		$	11.39
Grant-date fair value (per share) (Hawaiian Electric)	$	17.04		$	11.12

There were no share-based LTIP awards linked to TSR with a vesting date in 2026 and 2025.

As of March 31, 2026, there was $8.2 million of total unrecognized compensation cost related to the nonvested performance awards payable in shares linked to TSR. The cost is expected to be recognized over a weighted-average period of 2.1 years.

LTIP awards linked to other performance conditions. Information about HEI’s LTIP awards payable in shares linked to other performance conditions was as follows:

There were no share-based LTIP awards linked to other performance conditions with a vesting date in 2026 and 2025.

As of March 31, 2026, there was $1.1 million of total unrecognized compensation cost related to the nonvested shares linked to performance conditions other than TSR. The cost is expected to be recognized over a weighted-average period of 0.8 years.

Note 10 · Income taxes

The Company’s and Utilities’ effective tax rates (combined federal and state income tax rates) for the three months ended March 31, 2026 were 21% and 22%, respectively. This rate differs from the combined statutory rates, primarily due to the Utilities’ amortization of excess deferred income taxes related to the 2017 Tax Cuts and Jobs Act reduction in tax rate from 35% to 21%, partially offset by higher executive compensation limitations. The Company’s and Utilities’ effective tax rates were 19% and 21%, respectively, for the three months ended March 31, 2025.

On July 4, 2025, federal tax legislation, commonly referred to as the One Big Beautiful Bill Act (OBBBA), which includes a broad range of tax reform provisions, was signed into law in the United States. The Company recognized the impacts of OBBBA. The Company will continue to assess the legislation’s impact on future reporting periods; however, the legislation is not anticipated to have a material impact on the Company’s financial statements.

Currently, there are no active Internal Revenue Service income tax examinations. In January 2026, the Company was notified that the State of Hawaii will audit the Company’s income tax returns for the 2022 through 2024 tax years. The audit is ongoing, however, the Company has not received any audit adjustments at this time.

Note 12 · Fair value measurements

Fair value measurement and disclosure valuation methodology. The following are descriptions of the valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for financial instruments not carried at fair value:

Money market mutual funds. The Company considers all liquid investments purchased with an initial maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments.

Long-term debt. Fair value of fixed-rate long-term debt was obtained from third-party financial services providers based on the current rates offered for debt of the same or similar remaining maturities and from discounting the future cash flows using the current rates offered for debt of the same or similar risks, terms, and remaining maturities. The carrying amount of floating rate long-term debt approximated fair value because of the short-term interest reset periods. Long-term debt is classified in Level 2 of the valuation hierarchy.

The following table presents the carrying or notional amount, fair value and placement in the fair value hierarchy of the Company’s financial instruments.

Recent developments. For discussion of the impacts of inflation and other macro-economic factors impacting the Utilities, see also “Recent developments” in Hawaiian Electric’s MD&A. See also “Economic conditions” below for further discussion of the economic impact of recent events, and Note 2 of the Condensed Consolidated Financial Statements for recent updates and disclosures relating to the Maui windstorm and wildfires.

In June 2025, the Utilities submitted a request with the PUC to terminate or suspend the Affiliate Transaction Requirements (ATRs). Beginning in 2024 and continuing into 2026, HEI has embarked on a strategy to divest all of its affiliated companies other than the Utilities, intending for the Utilities to be HEI’s sole operating companies. Termination of the ATRs would allow implementation of a corporate integration, under which all HEI employees would move to Hawaiian Electric. A few officer positions would manage and operate both HEI and Hawaiian Electric (dual-hatted executives) and the HEI and Hawaiian Electric boards of directors would be composed of a single set of individuals. On October 31, 2025, HEI and Hawaiian Electric filed a revised request, after a September 2025 PUC order that provided guidance on the topics to be addressed in such a request. On March 23, 2026, the PUC issued an order approving the application of HEI and Hawaiian Electric to suspend the ATRs. The PUC’s approval is subject to specified commitments, including HEI’s divestment of all remaining Pacific Current and affiliated assets, a prohibition on pursuing new diversification activities, continued compliance with Hawaii Revised Statutes Section 269-19.5 governing affiliated interests, and ongoing cooperation with the PUC, including reporting obligations. HEI is required to file a report establishing a divestment timeline and to provide monthly progress reports thereafter. The order also requires advance notice to the PUC and Consumer Advocate prior to seeking any change in recovery of HEI-related expenses in future re-basing or rate proceedings. The PUC subsequently issued an order confirming that all ATR compliance filings and reporting are likewise suspended and closed the docket.

	Three months ended March 31				%
(in thousands)	2026		2025		change	Primary reason(s)1
Revenues	$	746,447	$	744,070	—	Increase in the electric utility, partly offset by a decrease in the all other segment.
Operating income	53,377		62,420		(14)	Lower operating income for the electric utility, partly offset by lower operating loss for the all other segment.
Net income for common stock	30,450		26,671		14	Lower net loss for the all other segment primarily due to the sale of Hamakua Holdings at Pacific Current in March 2025, partly offset by lower net income for the electric utility.

1 Also, see the all other segment discussion below.

The Company’s effective tax rates for the three months ended March 31, 2026 and 2025 were 21% and 19%, respectively. The increase in the effective tax rate was primarily due to the non-recurrence of a discrete tax benefit recognized in the prior-year period related to the sale of Hamakua Holdings. Excluding this discrete item, the effective tax rates for both periods were comparable.

Maui windstorm and wildfires related expenses, net. For the three months ended March 31, 2026 and 2025, the Company’s incremental expenses related to the Maui windstorm and wildfires as discussed in Note 2 of the Condensed Consolidated Financial Statements, were as follows:

1 Pursuant to the PUC order received on February 12, 2025, deferral accounting treatment limited to insurance premiums and outside services and legal costs associated with the asset-based lending facility credit agreement incurred in 2025 was granted. Applicable amounts were deferred to a regulatory asset. See “Risk Factors” in Item 1A. for further discussion of regulatory risks. See Note 2 of the Condensed Consolidated Financial Statements.

Note: The all other segment Maui windstorm and wildfires related expenses (legal, outside services and other) and insurance recoveries are included in “Expenses-Other” and interest expense is included in “Interest expense, net” on the HEI and subsidiaries Condensed Consolidated Statements of Income. See Electric utility section below for more detail.

From August 8, 2023 through March 31, 2026, HEI and its subsidiaries have incurred approximately $2.27 billion of Maui windstorm and wildfires related expenses, including the Utilities’ estimate of the losses related to a settlement of all wildfire tort-related legal claims and cross claims, the One ‘Ohana Initiative contribution and $47.8 million related to the securities class action settlement. Certain of these costs are reimbursable under excess liability insurance, professional liability insurance and directors and officers liability insurance policies. As of March 31, 2026, HEI and its subsidiaries have approximately $9 million, nil and $70 million of insurance coverage remaining under the excess liability, professional liability and directors and officers liability policies, respectively, after deducting applicable retention amounts, amounts that have been recovered under insurance policies (including the One ‘Ohana Initiative contribution), and amounts expected to be recovered for incurred costs, including the securities class action settlement, and recognized as a receivable as of the quarter end.

On April 10, 2026, the last condition to the finalization of the tort settlement agreements and first installment payment was satisfied when the last insurer agreed to a stipulation withdrawing with prejudice the appeal of the December 30, 2025 summary judgment entered in favor of HEI, Hawaiian Electric and other defendants. As a result, the Company paid the first of its four equal annual $479 million installments pursuant to the settlement agreements and has initiated efforts to recover the remaining unpaid insurance coverage under its excess liability policy.

Note: The statistical data in this section is from public third-party sources that management believes to be reliable (e.g., Board of Governors of the Federal Reserve System, Department of Business, Economic Development and Tourism, University of Hawaii Economic Research Organization (UHERO), U.S. Bureau of Labor Statistics, Honolulu Board of REALTORS®, and U.S. Energy Information Administration).

In the first quarter of 2026, the average daily passenger count was 2.7% lower than the comparable period in the prior year. The recovery in total passenger counts from the low levels in 2020, which occurred under COVID-19 restrictions, thus far has been driven by domestic travelers, with international travelers, including Japanese travelers, remaining at lower levels. In the first quarter, international visitor arrivals (excluding Japan) remained 20.1% below 2019 levels. Due to the weak yen, Japanese visitors are 38.6% below 2019 levels.

Hawaii’s preliminary seasonally adjusted unemployment rate in February 2026 was 2.3%, which was a decrease from the February 2025 rate of 2.6%. The national unemployment rate in March 2026 was 4.3%, slightly higher than the March 2025 rate of 4.2%. According to a recent forecast by UHERO, issued on February 27, 2026, jobs in the State will increase by 0.2% in 2026.

Hawaii real estate activity through March 2026, as indicated by Oahu’s home resale market, resulted in no change in the median sales price for condominiums and an increase of 2.6% for single-family homes compared to the same period in 2025. The median single-family home price was $1,205,000 in February 2026 and $1,199,500 in March 2026, both exceeding the previous all-time high of $1,185,000, set in February 2025. The number of closed sales through March 2026 saw a 3.6% decrease for condominiums and a 10.9% increase for single-family residential homes compared to the same period in 2025.

Hawaii’s petroleum product prices are correlated to the crude oil price in international markets. The price of crude oil has increased 5.8% over the same quarter in the prior year.

At its March 18, 2026 meeting, the Federal Open Market Committee (FOMC) decided to maintain the federal funds rate target range at 3.5% to 3.75%. The FOMC noted that uncertainty around the economic outlook remains elevated, and that the implications of developments in the Middle East for the U.S. economy are uncertain.

UHERO forecasts full year 2026 real GDP to increase 1.6%, real personal income to increase 0.9%, a decrease in total visitor arrivals of 0.6%, and an unemployment rate of 2.3% for the State. According to UHERO, Hawaii’s economy is gradually moving beyond a mild jobs recession in 2025 as payrolls have begun to edge upward, supported by a resilient U.S. economy and the local construction industry.

All other segment. The all other business segment loss includes results of the stand-alone corporate operations of HEI, ASB Hawaii, GLST1 and Pacific Current, including the results of Hamakua Energy and the solar and battery energy storage system facilities up until the close of their respective sales in 2025.


	Three months ended March 31
(in thousands)		2026		2025		Change		Primary reason(s)
Revenues		$	2,407	$	5,704	$	(3,297)	The revenues for the first three months of 2026 were lower than the comparable period in 2025 primarily due to lower revenues at Mahipapa and the sale of Hamakua Holdings in March 2025 and the solar and BESS facilities at Pacific Current1 in August 2025.
Operating loss		(9,156)		(13,517)		4,361		The first three months of 2026 and 2025 include $2.4 million and $5.2 million of operating loss, respectively, from Pacific Current1. The lower operating loss at Pacific Current is primarily due to the operating loss at Hamakua Holdings which was sold in March 2025. Corporate expenses for the first three months of 2026 were $1.7 million lower than the same period in 2025, primarily due to lower wildfire legal and other expenses.
Net loss		(4,893)		(21,145)		16,252		Lower operating losses due to the same factors cited for the change in operating loss above, lower interest expense (due to $384 million paydown in April 2025) and a loss on sale of Hamakua Holdings in March 2025, partly offset by lower interest and dividend income. Also see effective tax rate explanations above.

1 As a subsidiary of Hamakua Holdings, Hamakua Energy’s sales to Hawaii Electric Light (a regulated affiliate) up until the close of its sale on March 10, 2025, are eliminated in consolidation.

The all other business segment loss includes results of the stand-alone corporate operations of HEI (including eliminations of intercompany transactions) and the results of HEI’s subsidiaries, GLST1, ASB Hawaii and Pacific Current. Significant investments of Pacific Current made through its subsidiaries include: Pacific Current’s indirect subsidiary up until the close of its sale on March 10, 2025, Hamakua Energy, which owned a 60-MW combined cycle power plant on Hawaii Island that provides electricity to Hawaii Electric Light; Pacific Current’s solar project subsidiaries up until the close of the Solar Asset Disposition effective August 1, 2025, which includes Mauo, which owned solar-plus-storage projects totaling 8.6 MW on five University of Hawaii campuses, Alenuihaha Developments, LLC, which owned a collection of renewable energy assets on Oahu and Kauai, and Ka‘ie‘ie Waho Company, LLC, which owned a 6-MW solar photovoltaic system that provides renewable energy to Kauai Island Utility Cooperative; Pacific Current’s remaining operating subsidiary, Mahipapa, which owns a 7.5-MW nameplate biomass facility on Kauai; as well as eliminations of intercompany transactions.

In late February 2024, Hamakua Energy’s combustion turbine and its leased combustion turbine unexpectedly sustained damages from contaminated fuel resulting in a plant shut down through June 2024. In addition, in March 2024, a fire, which was ignited from a vendor’s welding activities during scheduled maintenance, destroyed the cooling tower at the Mahipapa facility on Kauai resulting in a plant shutdown through December 2024. The Company is currently working with its legal counsel on seeking recovery of its losses related to damages sustained to its plant facilities.

As part of HEI’s comprehensive review of strategic options for certain assets of Pacific Current, in March 2025, Pacific Current closed on the sale of Hamakua Holdings, a then wholly owned subsidiary of Pacific Current and parent company of Hamakua Energy, to an unaffiliated third party. In addition, in August 2025, Pacific Current, through an indirect subsidiary, sold all of its membership interests in Mauo, LLC, Alenuihaha Developments, LLC, Kaʻieʻie Waho Company, LLC and Upena, LLC, and agreed to sell all of its membership interest in Mahipapa to an unaffiliated third party. See Note 3 of the Condensed Consolidated Financial Statements for more information.

FINANCIAL CONDITION

Liquidity and capital resources. See “Credit and Capital Market Risk” in Item 1A. Risk Factors in HEI’s and Hawaiian Electric’s 2025 Form 10-K and in Item 1A. Risk Factors below.

The Company’s objective continues to be to operate a strong, financially healthy enterprise to empower a thriving future for Hawaii. In September 2025, HEI and Hawaiian Electric each entered into a fourth amended and restated credit agreement with a syndicate of eight financial institutions, increasing each of their committed capacities to $300 million (see Note 5 of the Condensed Consolidated Financial Statements). As of March 31, 2026, HEI and Hawaiian Electric had $15 million and nil, respectively, drawn on their revolving credit facilities and no commercial paper outstanding.

The Company has taken additional prudent measures to strengthen its financial position while continuing to provide reliable service to its customers and reinforcing HEI’s commitment to serving the community for the long term, including the Utilities entering into an asset-based credit facility in May 2024 that allows the Utilities to borrow up to $250 million (see Note 5 of the Condensed Consolidated Financial Statements), and HEI registering with the SEC in September 2024 an at-the-market offering program under which HEI may offer and sell, from time to time at its sole discretion, its common stock, without par value, having an aggregate offering price of up to $250 million. To date, HEI has not sold any common stock under this program. Additional proactive measures included suspending the quarterly cash dividend on HEI’s common stock after payment of the second quarter dividend in September 2023, repaying its revolving credit facilities and reducing or eliminating discretionary costs.

As of March 31, 2026, HEI consolidated had $2.4 billion of long-term debt, of which $125 million is due or expected to be repaid within 12 months. In addition, as of March 31, 2026, the Utilities accrued estimated wildfire liabilities of approximately $1.92 billion (pre-tax), related to the settlement of the Maui windstorm and wildfire tort-related legal claims (see Note 2 of the Condensed Consolidated Financial Statements). HEI and Hawaiian Electric determined that making payments under the terms of the Settlement Agreements in four equal annual installments is the most viable option and have classified the first $479 million installment as a current liability based on expected timing of the payment and the remaining $1.44 billion as a noncurrent liability on the Company’s and the Utilities’ Condensed Consolidated Balance Sheets. To finance the first installment payment, in September 2024, HEI completed the sale of 62.2 million shares of common stock. The shares were issued under a registration statement registering up to $575 million of common stock. The net proceeds from the sale of common stock amounted to approximately $557.7 million. In November 2024, HEI transferred the first installment payment to GLST1, a wholly owned subsidiary created for the specific purpose of holding the first installment payment pursuant to the

settlement of the Maui windstorm and wildfire tort-related legal claims (see Note 2 of the Condensed Consolidated Financial Statements). The cash for the first installment payment is classified as restricted cash on the Condensed Consolidated Balance Sheet as of March 31, 2026. On April 10, 2026, the final condition to payment occurred under settlement agreements and the first installment payment of $479 million was made.

The following table provides the components of available liquidity as of March 31, 2026. See “Liquidity and capital resources” in Hawaiian Electric’s MD&A below for components of its available liquidity under existing credit facilities as of March 31, 2026.

1 Pursuant to an HEI and Hawaiian Electric Intercompany Borrowing and Investment Policy which provides Hawaiian Electric a borrowing commitment of $75 million. Hawaiian Electric currently has no borrowings under this policy. See Note 5 of the Condensed Consolidated Financial Statements for a description of the HEI and Hawaiian Electric Intercompany Borrowing and Investment Policy.

Management believes with the Company’s cash and cash equivalents amount of $453 million and GLST1’s restricted cash amount of $479 million, both as of March 31, 2026, the available capacity on Hawaiian Electric’s ABL Facility, HEI’s and Hawaiian Electric’s increased borrowing capacities of their unsecured lines of credit, and additional liquidity under HEI’s registered at-the-market offering program, the Company has adequate cash to meet its financial obligations and sustain operations in the short term.

The Company expects that liquidity will continue to be impacted in the long term primarily due to the remaining liability payments to settle wildfire claims; the August 2023 downgrades of the Company’s credit ratings to below investment grade, which may limit the Company from readily accessing low-cost unsecured, short-term borrowings and other sources of debt and equity financing on favorable terms; and higher working capital requirements resulting from inflation and elevated fuel prices. Although the Company has raised sufficient cash to pay the first installment of the settlement of wildfire tort claims, the Company is currently working with its financial advisors on a financing plan to raise the additional capital necessary to fund the remaining settlement payments for the wildfire tort claims. While management believes the Company will be able to raise the necessary capital, there is no assurance that management’s plans will be successful. If the financing plans are unsuccessful, the Company may need to consider other strategic alternatives. See further discussion in “Risk Factors” in Item 1A. If further liquidity is deemed necessary in the short term, Hawaiian Electric could also reduce the pace of capital spending related to non-essential projects, manage O&M expenses, seek borrowings on a secured basis, and explore asset sales.

Credit ratings. On March 17, 2026, S&P revised HEI’s outlook to “Positive” from “Credit Watch Positive” and reaffirmed the “B+” issuer credit rating. On April 21, 2026, Moody’s upgraded HEI’s long-term issuer rating to “Ba2” from “Ba3,” and changed its outlook to “Stable” from “Positive.”

HEI consolidated material cash requirements. Material cash requirements of HEI consolidated include: payments related to settlement of tort-related legal claims and cross claims; Utility-related capital expenditures (including capital expenditures related to wildfires and wildfire mitigations), labor and benefits costs, O&M expenses, fuel and purchase power costs, and debt and interest payments; HEI-related labor and benefits costs, debt and interest payments and legal and consulting costs related to the Maui windstorm and wildfires; and HEI equity contributions to support Pacific Current’s remaining operating subsidiary.

The consolidated capital structure of HEI was as follows:


(dollars in millions)	March 31, 2026				December 31, 2025

Long-term debt, net, including current portion of long-term debt, net	$	2,405	59	%	$	2,410	60	%

Common stock equity	1,637		41		1,606		40
	$	4,042	100	%	$	4,016	100	%

HEI also periodically makes short-term loans to Hawaiian Electric to meet Hawaiian Electric’s cash requirements, including the funding of loans by Hawaiian Electric to Hawaii Electric Light and Maui Electric, but no such short-term loans to Hawaiian Electric were outstanding as of March 31, 2026.

See Note 5 of the Condensed Consolidated Financial Statements for a brief description of the Company’s loans.

There were no new issuances of common stock through the DRIP or the HEIRSP for the three months ended March 31, 2026 and 2025.

For the first three months of 2026, net cash provided by operating activities of HEI consolidated was $61 million. Net cash used in investing activities for the same period was $102 million, primarily due to capital expenditures. Net cash used in financing activities for the same period was $8 million, primarily due to repayment of long-term debt.

Dividends. The payout ratios for the first three months of 2026 and full year 2025 were nil. Each quarter, the HEI Board of Directors evaluates whether to declare a dividend and considers many factors in the evaluation including, but not limited to, the Company’s results of operations, liquidity, the long-term prospects for the Company, current and expected future economic conditions, and capital investment alternatives. In August 2023, in consideration of the potential impact from the Maui windstorm and wildfires, the HEI Board of Directors voted to suspend the quarterly cash dividend, starting after the second quarter 2023 dividend, and has not declared a cash dividend since that time. This action was intended to allow the Company to provide additional liquidity and allocate resources to reducing wildfire risk and rebuilding and restoring power and help ensure a strong future for the Utilities. In May 2025, after a temporary suspension of Hawaiian Electric’s quarterly cash dividend to HEI that began with the second quarter 2024 dividend, the Hawaiian Electric Board of Directors approved a $10 million dividend for each quarter of 2025 and an $11 million dividend for the first quarter of 2026. This decision was made after considering several factors, including the continued progress of the Maui windstorm and wildfire settlement, the Utilities’ results of operations and the Utilities’ liquidity position.

MATERIAL ESTIMATES AND CRITICAL ACCOUNTING POLICIES

In preparing financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results could differ significantly from those estimates.

In accordance with SEC Release No. 33-8040, “Cautionary Advice Regarding Disclosure About Critical Accounting Policies,” management has identified the accounting policies it believes to be the most critical to the Company’s financial statements—that is, management believes that these policies are both the most important to the portrayal of the Company’s results of operations and financial condition, and currently require management’s most difficult, subjective or complex judgments.

For information about these material estimates and critical accounting policies, in addition to the critical policy discussed below, see pages 42, 43, 61 and 62 of the MD&A included in Part II, Item 7 of HEI’s and Hawaiian Electric’s 2025 Form 10-K.

Following are discussions of the results of operations, liquidity and capital resources of the electric utility segment.

Electric utility

Recent developments. See also “Recent developments” in HEI’s MD&A and Note 2 of the Condensed Consolidated Financial Statements, which includes disclosures relating to Maui windstorm and wildfires.

For the first quarter of 2026, the Utilities generated net income of approximately $35.3 million compared to $47.8 million for the same quarter of 2025. See “Results of operations” below for variance explanations.

In the first quarter of 2026, kWh sales volume increased 0.4% compared to the same period in 2025. The increase is driven by cloudier weather conditions, reducing production from rooftop solar and solar water heaters.

The price of crude oil has increased 5.8% over the same quarter in the prior year. The Utilities are able to pass through fuel costs to customers and have limited fuel cost exposure through a 2% fuel cost-risk sharing mechanism (approximately $3.7 million maximum penalty/reward exposure annually).

In March 2026, the Consumer Price Index (CPI) increased 3.3% over the last 12 months. In Hawaii, the March 2026 Urban Hawaii (Honolulu) CPI increased 3.7% over the last 12 months. Under the PBR Framework, inflation risk for the Utilities is partially mitigated by an Annual Revenue Adjustment (ARA), which is based on a formula that includes a compounded and non-compounded portion.

•The compounded portion of the ARA includes an adjustment for the annual change in inflation based on the estimated change in Gross Domestic Product Price Index (GDPPI) for the upcoming year, less a predetermined annual productivity factor (currently set at zero), less a 0.22% customer dividend, applied to a basis equal to test year target revenues plus the Rate Adjustment Mechanism revenue in effect prior to the implementation of PBR, plus the prior adjustment year’s compounded portion of the ARA. The inflation factor percentage is the consensus projection of annual percentage change in GDPPI for the following calendar year published by Blue Chip Economic Indicators each October. For the 2025 calendar year, the forecasted 2025 GDPPI was 1.98% (net of the 0.22% customer dividend), measured in October 2024, and became effective in rates on January 1, 2025. For the 2026 calendar year, the forecasted 2026 GDPPI was 2.58% (net of the 0.22% customer dividend), measured in October 2025, and became effective in rates on January 1, 2026.

•The non-compounded portion of the ARA includes a subtractive component, representing the management audit savings commitment, or refund to customers, which was approved by the PUC to supplement the 0.22% customer dividend discussed above to make up the total customer dividend that will be applied to the ARA formula during the multi-year rate period (MRP).

Recent regulatory and legislative developments.

Alternative re-basing. In its order issued on February 27, 2025, the PUC concluded that Utilities’ target revenues should be re-based for the next MRP (MRP2) and allowed the Utilities to file a single, consolidated application that presents their requested adjustment to target revenues. The proceeding to re-base the Utilities’ target revenues for MRP2 shall be bifurcated into two tracks, with the first track focused on reaching a decision on the Utilities’ revenue requirements prior to the commencement of MRP2 and the second track focused on making a final determination on the revenue requirement and addressing the rate design component. On March 6, 2026, the Utilities filed a joint alternative re-basing proposal with Ulupono Initiative, requesting an increase of $170 million over annual target revenues at current effective rates, with $125 million phased into revenues in the first year of MRP2 and the remaining $45 million implemented in the second year of MRP2. The Utilities are awaiting PUC guidance on the procedural process to review the joint alternative re-basing proposal.

See “Regulatory proceedings” in Note 4 of the Condensed Consolidated Financial Statements.

Affiliate transactions. In June 2025, the Utilities submitted a request with the PUC to terminate or indefinitely suspend all or specific provisions of the Affiliate Transaction Requirements (ATRs). On October 31, 2025, HEI and Hawaiian Electric filed a revised request, after a September 2025 PUC order that provided guidance on topics to be addressed in such a request. Beginning in 2024 and continuing into 2026, HEI has embarked on a strategy to divest all of its affiliated companies other than the Utilities, intending for the Utilities to be HEI’s sole operating companies. In their filing, HEI and Hawaiian Electric described how termination or suspension of the ATRs would allow implementation of a corporate integration, under which all HEI employees would move to Hawaiian Electric, a few officer positions would manage and operate both HEI and Hawaiian Electric (dual-hatted executives), and the HEI and Hawaiian Electric boards of directors would be composed of a single set of individuals. On March 23, 2026, the PUC issued an order approving the indefinite suspension of ATR provisions requested by HEI and Hawaiian Electric. The PUC’s approval is subject to specified commitments, including HEI’s divestment of all remaining Pacific Current and affiliated assets, a prohibition on pursuing new diversification activities, continued compliance with Hawaii Revised Statutes Section 269-19.5 governing affiliated interests, and ongoing cooperation with the PUC, including reporting obligations. HEI is required to file a report establishing a divestment timeline for remaining affiliate assets and to provide monthly progress reports thereafter. The order also requires advance notice to the PUC and Consumer Advocate prior to seeking any change in recovery of HEI-related expenses in future re-basing or rate proceedings. The PUC subsequently issued an order confirming that all ATR compliance filings and reporting are likewise suspended and closed the docket.

System reliability. Since the August 2023 Maui windstorm and wildfires, the Utilities have developed a set of interim wildfire safety measures to mitigate the risk of wildfires in areas identified as having higher risk of wildfire in all service territories (Oahu, Maui County, and Hawaii Island). These interim measures represent actions the Utilities performed in 2024. On January 10, 2025, the Utilities filed their 2025-2027 Wildfire Safety Strategy (WSS, also referred to as Wildfire Mitigation Plan or WMP) with the PUC, which outlines their plans to reduce wildfire risk throughout their service territories over the next three years, and was approved by the PUC on December 31, 2025. The PUC also directed the Utilities to provide a WMP update bi-annually. On April 13, 2026, the Utilities submitted their 2026-2027 WMP update to the PUC. The WMP update primarily reflects 1) maturation of the wildfire mitigation framework following the 2025-2027 WSS, 2) direct responses to the PUC’s areas of continuous improvement identified in a decision and order, and 3) other non-substantive revisions for clarity. These measures result in disruptions to service and negatively impact Transmission and Distribution (T&D) System Average

Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI). While the Utilities work to refine these measures over time to mitigate customer impacts, the Utilities are currently focused on taking immediate steps to keep island communities safe during extreme weather events. For a discussion regarding the launch of the Public Safety Power Shutoff program, see discussion below under “Wildfire safety measures.”

Hawaii Island has two generators out of service for extended maintenance, one of which is expected to return to service in the second quarter of 2026. While these units are unavailable for maintenance, during certain periods there may be reductions in generation reserve margins and failure of other generators, which could risk generation shortfalls.

For a discussion regarding the impact of the Maui windstorm and wildfires on the Utilities’ liquidity and capital resources, see discussion below under “Financial Condition–Liquidity and capital resources.”

1The rate schedules of the Utilities currently contain Purchased Power Adjustment Clauses (PPACs) through which changes in purchased power expenses (except purchased energy costs) are passed on to customers.

2The rate schedules of the Utilities currently contain Energy Cost Recovery Clauses (ECRCs) through which changes in fuel oil prices and certain components of purchased energy costs are passed on to customers.

3 Starting in the fourth quarter of 2025, certain Wildfire Safety Strategy costs were deferred and continued to be deferred in 2026.

4 kWh sales were slightly higher compared to the same quarter in prior year. The increase in sales can be attributed to cloudier weather conditions, reducing production from rooftop solar and solar water heaters.

The Utilities’ effective tax rates for the first three months of 2026 and 2025 were relatively comparable at 22% and 21%, respectively.

Hawaiian Electric’s consolidated return on average common equity (ROACE) was 10% and not meaningful for the twelve months ended March 31, 2026 and 2025, respectively.

For more information of the Utilities’ incremental expenses related to the Maui windstorm and wildfires for the three months ended March 31, 2026 and 2025, see “Results of operations—Maui windstorm and wildfires related expenses” in HEI’s MD&A.

See “Economic conditions” in the “HEI consolidated” section above.

Executive overview and strategy. The Utilities provide electricity on all the principal islands in the State of Hawaii, other than Kauai, to approximately 95% of the State’s population, and operate five separate grids. The Utilities’ mission is to empower their communities and customers with safe, reliable, resilient, affordable, and clean energy. The goal is to create a safe, modern, resilient, flexible, and dynamic electric grid that protects Hawaii from impacts of climate dynamics, position the Utilities to achieve the expectations of their customers and communities and earn their trust, and achieve Hawaii’s decarbonization goals that are aligned with the statutory goal of 100% renewable portfolio standard and net-negative carbon emissions by 2045.

Wildfire safety measures. In January 2025, the Utilities developed and filed with the PUC a 2025-2027 Wildfire Safety Strategy (WSS), which identifies risk mitigation strategies to perform over the next three years across their service territories. The measures, including wildfire risk analysis, implementation of the Public Safety Power Shutoff (PSPS) program, grid design changes, and system hardening, have been integrated into the 2025-2026 WSS. The strategies and actions include additional operational changes, grid hardening work, enhanced inspections and vegetation management, and risk modeling to inform and prioritize hardening work and operational actions. On May 30, 2025, the Utilities submitted an application to the PUC for Exceptional Project Recovery Mechanism (EPRM) cost recovery estimated at $350 million, net of costs funded through other existing programs. On December 31, 2025, the PUC approved the Utilities’ 2025-2027 WSS. The PUC also directed the Utilities to provide a WMP update bi-annually. On April 13, 2026, the Utilities submitted their 2026-2027 WMP update to the PUC.

The PSPS program calls for the Utilities to preventatively de-energize circuits in areas identified as high fire risk during certain weather conditions. The PSPS program launched on July 1, 2024 has been used when it is needed, to protect customers, communities and employees. Since the July 2024 implementation, the Utilities have continued to mature the PSPS program as it has gained experience executing the program along with public safety partners, communities, and residents. For example, the Utilities now have an in-house meteorologist and additional strategically placed weather stations to enhance their forecasting capability and situational awareness of localized hazardous conditions. The PSPS protocols will evolve over time as more analytical, forecast, and situational awareness capabilities and wildfire mitigations are deployed. De-energizing circuits in high wildfire risk areas will lead to extended interruptions for many customers, even if not in a high wildfire risk area. The Utilities will continue to work with key stakeholders in balancing the risk of utility-related wildfires with the risk to the public arising from not having electricity.

Transition to a decarbonized and sustainable energy future. The Utilities are fully committed to leading and enabling pathways to a decarbonized and sustainable energy future for Hawaii. A sustainable energy future is one that focuses on delivering electricity safely, reliably and affordably, strengthening resilience and shifting away from fossil-fueled resources. The Utilities believe that a holistic approach to evolving climate dynamics is needed, working on both climate mitigation efforts along with climate adaptation efforts. Climate mitigation requires achieving the Utilities’ decarbonization and renewable energy commitments, facilitating and promoting beneficial electrification, and deploying carbon removal and offsets among other levers to reduce statewide emissions.

Climate action plan. In the fourth quarter of 2021, the Utilities outlined their Climate Action Plan to cut carbon emissions from power generation 70% by 2030, compared to a 2005 baseline. The emissions covered by this goal include stack emissions from generation owned by Hawaiian Electric and IPPs who sell electricity to the Utilities. Since that time, delays and cancellations in the commercial operation of new renewable third-party generation resources and higher costs as a result of supply chain disruptions and inflationary pressures, as well as federal policies have slowed the pace of progress toward reducing greenhouse gas emissions. Also, see the “Developments in renewable energy efforts—New renewable PPAs” section below. The One Big Beautiful Act signed into law on July 4, 2025 may impact the ability of recently selected and new wind and solar projects to qualify for federal tax credits. Any loss in renewable energy tax credits could lead to project risk for new wind and solar projects in development and will likely result in higher prices for new renewable projects, which rely on such incentives to provide clean, affordable energy. Further, new tariffs imposed on equipment and materials used in the construction of renewable facilities will have an impact on pricing of new renewable projects. As a result of these challenges and the

downgrade of Hawaiian Electric’s credit ratings after the Maui windstorm and wildfires, the Utilities expect the planned 70% reduction in carbon emissions to be achieved later than the original 2030 target date. However, the Utilities will continue to replace significant amounts of fossil fuel generation with renewable energy between now and 2030 RPS goals and expect to meet or exceed the State of Hawaii’s 2030 RPS goals. The Utilities estimate a reduction of carbon emissions of approximately 25% for 2025. This represented an increase in emissions compared to the 27% reduction in 2024 due to higher customer electric usage. As renewable energy replaces fossil fuel generation, carbon emissions are expected to continue to decline over time.

Hawaiian Electric has also committed to achieving net zero carbon emissions from power generation by 2045 or sooner. While the timing of the Utilities’ carbon reduction goals will be impacted by federal policies, key elements of the 2030 plan have already been completed or remain on track to be completed by 2030, including the closure of AES Hawaii, Inc., the State’s last coal-fired IPP plant, increasing rooftop solar by more than 50% over 2021 levels, retiring six fossil fuel generating units, increasing grid-scale and customer-owned storage, expanding geothermal resources, and creating customer incentives for using clean, lower-cost energy at certain times of the day and using less fossil-fueled energy at night. The retirement of fossil-fueled generating units is consistent with state policy and supported by Hawaii state law.

State of Hawaii laws and policies. In January 2025, the State of Hawaii issued two key policy documents and an alternative fuel study. The PUC issued its 2024 Inclinations on the Future of Energy in Hawaii (2024 PUC Inclinations). The 2024 PUC Inclinations are intended to provide a guide for the completion of energy infrastructure upgrades for public safety, reliability and resiliency. This includes among other items, strategic hardening, diversification and enhancements of transmission and distribution systems, expedited replacement of older fossil fired generation, streamlined interconnection for renewable utility scale and distributed energy resources, including a specific goal to limit fossil fuel generation to no more than 40% on each island by 2030, software and hardware improvement to prevent cybersecurity threats, creation of resilience hubs, and integration of electric, gas, and renewable resources to support continuity of energy, telecommunications, water and wastewater services. The 2024 PUC Inclinations specifically state that “Strategic ownership of new generation (by the Utilities) may be beneficial, especially when such ownership stabilizes utility finances, benefits from low-interest federal loans or advances other objectives such as operational accountability, resilience and public safety.”

Governor Josh Green issued Executive Order No. 25-01, Accelerating Hawaii’s Transition Toward 100 Percent Renewable Energy (EO 25-01). EO 25-01 sets forth collective actions to accelerate the State’s decarbonization, stabilize and reduce energy costs, lower the State’s carbon footprint, strengthen energy security, and gain access to capital for the energy transition. Among other actions, EO 25-01 calls for 100% renewable electricity production in the counties of Hawaii and Maui by 2035 and achieving a 70% reduction of Oahu’s greenhouse gas emissions reductions from the electricity sector by 2035, using 2005 as a baseline, calls for the maximization of distributed solar energy paired with energy storage, including the installation of 50,000 new distributed energy resources by 2030, accelerating permitting tied to renewable energy, approving interconnection, and addressing energy burdens on low- and moderate-income residents.

The Hawaii State Energy Office’s Alternative Fuel, Repowering and Energy Transition Study (Alternative Fuel Study) expresses concern about the speed of the transition to renewable energy and cites to the continued reliance on imported oil as a driver of high bills and intense carbon emissions. The report makes a case for the use of liquefied natural gas on Oahu to replace low sulfur fuel oil during the transition to 100% renewable energy, and names several entities as potential investors that could help speed the transition. On October 6, 2025, the Office of the Governor of the State of Hawaii and JERA Co., Inc. (JERA), Japan’s largest power producer, signed a non-binding Strategic Partnering Agreement that establishes a framework for long-term collaboration to support Hawaii’s decarbonization goals and energy transition. The Strategic Partnering Agreement supports the implementation of the Hawaii State Energy Office’s Alternative Fuel Study to pursue fuel diversification, including liquified natural gas, to reduce near-term reliance on oil. On March 17, 2026, JERA provided a proposal to the State of Hawaii to modernize Oahu’s energy system to accelerate the replacement of oil-fired generation with new energy assets, including an approximately 500-MW hybrid combined-cycle and simple-cycle power facility supported by offshore liquefied natural gas import infrastructure. JERA is exploring opportunities to participate in the equity investment needed, and if the project is approved, JERA estimates the new infrastructure would be developed over the next several years, with a target commercial operation date in 2030.

The Utilities are engaged in planning activities designed to support the State’s energy policy objectives, including the transition to a more affordable, reliable, and sustainable energy system. These planning efforts evaluate a range of resource, fuel, and technology options and are informed by state energy policy guidance and stakeholder input. Importantly, all three documents recognize that to achieve the State’s ambitious goals is a collective effort that will require government agencies, electric utilities, and private stakeholders to work together, acknowledging that each of these groups has an important role to play. The 2024 PUC Inclinations for example state: “Energy utilities, government agencies and private stakeholders must embrace an ethos of collective responsibility to confront and effectively mitigate the vulnerabilities revealed by Lahaina’s heartbreaking tragedy, the COVID pandemic, ongoing global unrest, cybersecurity threats and the overarching climate crisis.” The PUC later states: “The Commission does not expect energy utilities to accelerate their transformation without regulatory assistance and third-party resources.” All three documents also recognize the progress made to date towards the State’s

renewable energy goals. The Utilities remain committed to working with all stakeholders to support the State’s energy policy objectives and reach Hawaii’s ambitious renewable energy goals.

Hawaii’s renewable portfolio standard law requires electric utilities to meet an RPS of 30%, 40%, 70% and 100% by December 31, 2020, 2030, 2040 and 2045, respectively. Hawaii law has also established a target of sequestering more atmospheric carbon and greenhouse gases than emitted within the State by 2045. The Utilities’ strategies and plans are fully aligned in meeting these targets (see also “Integrated Grid Planning” below).

The Utilities have made significant progress on the path to clean energy and have been successful in achieving RPS goals. To date the Utilities have met all of the statutory RPS goals, including exceeding the latest milestone RPS target of 30% for 2020, where it achieved an RPS of 34.5%. The Utilities expect to continue to meet the RPS milestones under the amended RPS law. See “Developments in renewable energy efforts” below.

If the Utilities are not successful in meeting the RPS targets as mandated by law, the PUC could assess a penalty of $20 for every megawatt-hour (MWh) that an electric utility is deficient. Based on the level of total generation in 2025, a 1% shortfall in meeting the 2030 RPS requirement of 40% would translate into a penalty of approximately $2.1 million. The PUC has the discretion to reduce the penalty due to events or circumstances that are outside an electric utility’s reasonable control, to the extent the event or circumstance could not be reasonably foreseen and ameliorated. In addition to penalties under the RPS law, failure to meet the mandated RPS targets would be expected to result in a higher proportion of fossil fuel-based generation than if the RPS target had been achieved, which in turn would be expected to subject the Utilities to limited commodity fossil fuel price exposure under a fuel cost risk-sharing mechanism. The fuel cost risk-sharing mechanism apportions 2% of the fuel cost risk to the Utilities (and 98% to ratepayers) and has a maximum exposure (or benefit) of $3.7 million. Conversely, the Utilities have incentives under PIMs that provide a financial reward for accelerating the achievement of renewable generation as a percentage of total generation, including customer supplied generation. In 2025, the Utilities achieved a 36.8% RPS accruing a reward of $1.9 million based on $10/MWh in exceedance of 35.0% RPS. In 2026, the Utilities are eligible for a reward of $10/MWh in exceedance of 36.0% RPS.

The Utilities are fully aligned with, and supportive of, state policy to achieve a decarbonized future and have made significant progress in reducing emissions through renewable energy and electrification. This alignment with state policy is reflected in management compensation programs and the Utilities’ long-range plans, which include aspirational targets in order to catalyze action and accelerate the transition away from fossil fuels throughout their operations at a pace more rapid than dictated by current law. The long-range plans, including aspirational targets, serve as guiding principles in the Utilities’ continued transformation, and are updated regularly to adapt to changing technology, costs, and other factors. While there is no financial penalty for failure to achieve the Utilities’ long-range aspirational objectives, the Utilities recognize that there are environmental and social costs from the continued use of fossil fuels.

The State of Hawaii’s policy is supported by the regulatory framework and includes a number of mechanisms designed to maintain the Utilities’ financial stability during the transition toward the State’s decarbonized future. Under the sales decoupling mechanism, the Utilities are allowed to recover from customers, target test year revenues, independent of the level of kWh sales, which have generally trended lower over time as privately-owned distributed energy resources have been added to the grid and energy efficiency measures have been put into place. Other regulatory mechanisms under the PBR Framework reduce some of the regulatory lag during the multi-year rate plan, such as the annual revenue adjustment to provide annual changes in utility revenues, including inflationary adjustments, and the EPRM, which allows the Utilities to recover and earn on certain approved eligible projects placed into service. See “Regulatory proceedings” in Note 4 of the Condensed Consolidated Financial Statements.

Integrated grid planning. Achieving high levels of renewable energy and a carbon free electric system will require modernizing the grid through coordinated energy system planning in partnership with local communities and stakeholders. To accomplish this, the Utilities are implementing an innovative systems approach to energy planning intended to yield the most cost-effective renewable energy and decarbonization pathways that incorporates customer and stakeholder input.

The Integrated Grid Planning (IGP) process utilizes an inclusive and transparent stakeholder engagement model to provide an avenue for interested parties to engage with the Utilities and contribute meaningful input throughout the IGP process. The first cycle of the IGP was accepted by the PUC on March 7, 2024, and is the culmination of more than five years of partnership with stakeholders and community members across the islands. Together, they forecasted future energy needs and identified strategies to meet Hawaii’s growing energy demand with 100% renewable resources. The Integrated Grid Plan proposes actionable steps to decarbonize the electric grid on the State of Hawaii’s timeline, with a flexible framework that can adapt to future technologies. On January 2, 2026, the PUC opened the Second Cycle of the Integrated Grid Plan to continue to plan for future resources needed on the Utilities’ systems.

Demand response programs. Pursuant to PUC orders, the Utilities are developing an integrated Demand Response Portfolio Plan that will enhance system operations and reduce costs to customers. The reduction in cost for the customer will

take the form of either rates or incentive-based programs that will compensate customers for their participation individually, or by way of engagements with turnkey service providers that contract with the Utilities to aggregate and deliver various grid services on behalf of participating customers and their distributed assets.

In 2022, the Utilities were approved to expand the Energy Demand Response Program (EDRP) on the island of Maui and Oahu, which provides approximately 8 MW and 43 MW on Maui and Oahu, respectively. The PUC approved the cost recovery of the additional incentives for both Oahu and Maui through the Demand Side Management Surcharge.

During the time that EDRP was available, Bring Your Own Device Level 1 was launched on April 1, 2025, to succeed EDRP, which closed on July 1, 2024, on Oahu. The Bring Your Own Device Level 1 later evolved into Bring Your Own Device Plus, which began on May 15, 2025. Enrollment for the Bring Your Own Device Plus program will be available until total enrolled program capacity reaches 50 MW statewide.

Grid modernization. The overall goal of the Grid Modernization Strategy (GMS) is to deploy modern grid investments at an appropriate priority, sequence and pace to cost-effectively maximize flexibility, minimize the risk of redundancy and obsolescence, deliver customer benefits and enable greater resiliency, reliability, distributed energy resources and renewable energy integration.

The Utilities filed their initial application with the PUC on September 30, 2019 for an Advanced Distribution Management System as part of Phase 2 of their GMS implementation. However, as the Utilities were unsuccessful in securing Infrastructure Investment and Jobs Act federal funding in 2024, the Utilities are currently re-scoping GMS Phase 2 and plan to file another updated and supplemented PUC application for updated project costs in the second quarter of 2026.

Investigation on the establishment of wheeling. On July 1, 2024, the PUC issued an order to institute a proceeding to investigate the establishment of electricity wheeling policies and procedures for the electric utilities for the State of Hawaii. The PUC stated that it intended to address matters using lessons learned in the initial three docket phases to explore implementation of an intragovernmental wheeling policy and an evaluation of retail wheeling in subsequent phases, as appropriate.

On August 29, 2025, the PUC issued an order dividing the proceeding into two tracks, Track A, focused on retail wheeling, and Track B, focused on an intragovernmental credit share program that was the subject of the prior procedural schedule in the docket.

On October 22, 2025, the Utilities filed feedback on the PUC’s proposed Track B, Intragovernmental Shared Credit Program. The Utilities support the program but emphasize that careful program design is necessary to ensure technical feasibility, administrative efficiency, and fairness for all customers. The Utilities agree that the program could support the development of renewable energy zones by unlocking government lands for renewable projects and enabling proactive transmission planning.

On November 10, 2025, the Utilities filed their Track A Retail Wheeling Straw Proposal. The Utilities’ Straw Proposal provides an overview for the application process, a discussion of technical standards for grid interconnection and monitoring, provisions for metering and monitoring and a discussion of pricing mechanisms in the tariff structure and how to appropriately allocate wheeling costs. The Consumer Advocate and stakeholders provided comments on the Utilities’ Straw Proposal by January 20, 2026. The Utilities filed responses to the comments of the Consumer Advocate and stakeholders on March 6, 2026. On April 7, 2026, the PUC held a technical conference and stakeholder workshop where the Utilities provided a presentation on the Track A Retail Wheeling Straw Proposal and addressed the various comments and questions raised by the PUC, Consumer Advocate, and stakeholders in the proceeding. At the end of the conference, the PUC stated it would be issuing further guidance on the docket and a procedural schedule for the remainder of the proceeding.

Regulatory proceedings. On December 23, 2020, the PBR D&O was issued, establishing the PBR Framework. The PBR Framework implemented a five-year multi-year rate period (MRP), during which there will be no general rate case applications. The Utilities are currently exploring a collaborative non-rate case re-basing proposal under the PBR Framework as an alternative to a rate case process. See “Regulatory proceedings” in Note 4 of the Condensed Consolidated Financial Statements for a discussion of re-basing, PBR Framework and decoupling.

Regulated returns. As part of the PBR Framework’s annual review cycle, the Utilities track their rate-making ROACEs as calculated under the earnings sharing mechanism, which includes only items considered in establishing rates. At year-end, each utility’s rate-making ROACE is compared against its ROACE allowed by the PUC to determine whether earnings sharing has been triggered. The D&O in the PBR proceeding modified the earnings sharing mechanism to a symmetric arrangement. Effective with annual earnings for 2021, the earnings sharing will be triggered for achieved rate-making ROACE outside of a 300 basis points dead band above and below the current authorized rate-making ROACE of 9.5% for each of the Utilities (i.e., above 12.5% or below 6.5%). Earnings sharing credits or recoveries will be included in the biannual report (formally known as annual decoupling filing) to be filed with the PUC in the spring of the following year.

On August 31, 2023, the PUC issued an order temporarily suspending the Earnings Sharing Mechanism (ESM) until further notice. The intent of the order is to address the unintended consequence of customers potentially bearing the costs associated with the Maui windstorm and wildfires through the operation of the ESM without prior PUC review. In accordance with the order, the ESM remains suspended and there is no earnings sharing adjustment for 2026 as of March 31, 2026.

Actual and PUC-allowed returns, as of March 31, 2026, were as follows:


Ratio (%)	Rate-making Return on rate base (RORB)1			Book ROACE2			Rate-making ROACE3
Twelve months ended March 31, 2026	Hawaiian Electric	Hawaii Electric Light	Maui Electric	Hawaiian Electric	Hawaii Electric Light	Maui Electric	Hawaiian Electric	Hawaii Electric Light	Maui Electric
Utility returns	7.36	6.64	4.13	14.11	9.36	2.66	9.02	8.04	3.60
PUC-allowed returns	7.37	7.52	7.43	9.50	9.50	9.50	9.50	9.50	9.50
Difference	(0.01)	(0.88)	(3.30)	4.61	(0.14)	(6.84)	(0.48)	(1.46)	(5.90)

1 Based on recorded operating income and average rate base, both adjusted for items not included in determining electric rates.

2 Based on recorded net income divided by average common equity.

3 Based on recorded net income adjusted to remove items not included in determining electric rates, divided by rate making equity.

Rate-making calculations remove the impacts of the Settlement Agreements and eliminate the balances for the asset-based lending facility (ABL Facility) on a stand-alone company basis. The Utilities have stated that customers will not be impacted by payments related to the Settlement Agreements for the Maui windstorm and wildfires, which totals $1.9 billion (see Note 2 of the Condensed Consolidated Financial Statements). The ABL Facility contains certain intercompany costs related to the ABL Facility that are eliminated on a consolidated basis, and these transactions are eliminated on a stand-alone company basis for rate-making. Therefore, the rate-making returns were adjusted to exclude these impacts.

The gap between PUC-allowed ROACEs and the ROACEs achieved is generally due to the exclusion of certain expenses from rates (for example, incentive compensation and charitable contributions), and depreciation, other operation and maintenance (O&M) expense and return on rate base that are in excess of what is currently being recovered through rates (the last rate case plus authorized Rate Adjustment Mechanism revenue and ARA revenues). In 2025, Maui Electric's returns are lower than allowed levels due to higher sustained maintenance and investments than what is recovered in current rates.

Developments in renewable energy efforts. The Utilities continue to procure renewable energy ambitiously. The Utilities’ renewable energy goals depend, in large part, on the success of renewable projects developed and operated by independent power producers. Significant project delays or failures of these projects increase the risk of the Utilities not meeting the renewable portfolio standards or other climate related goals, eligibility for Performance Incentive Mechanisms associated with the speed of increasing renewable generation, and the ability to retire fossil fuel units. Developments in the Utilities’ efforts to further their renewable energy strategy include renewable energy projects discussed in Note 4 of the Condensed Consolidated Financial Statements and the following:

New renewable PPAs.

•Under a request for proposal process governed by the PUC and monitored by independent observers, the Utilities issued Stage 2 Renewable RFPs for Oahu, Maui and Hawaii Island and Grid Services RFP on August 22, 2019. Of the 11 PPAs filed by the Utilities, six PPAs were declared null and void by the independent power producers and one PPA was mutually terminated. The four remaining projects have received PUC approval. The Utilities filed three requests with the PUC for approval of amendments related to previously-approved PPAs for changes in pricing and/or guaranteed commercial operations dates to support completion of the projects while maintaining system reliability. The PUC approved all three amendments. To date, two Stage 2 projects have reached commercial operations. See also “Purchase commitments” in Note 4 of the Condensed Consolidated Financial Statements. Separately, the PUC approved the Utilities’ Waena Battery Energy Storage System project under Stage 2. See “Utility projects” in Note 4 of the Condensed Consolidated Financial Statements.

A summary of the remaining four approved Stage 2 PPAs and the self-build project is as follows:


Utilities	Number of contracts	Total photovoltaic size (MW)	BESS Size (MW/MWh)			Guaranteed commercial operation dates	Contract term (years)	Total projected annual lump sum payment (in millions)
PPAs
Hawaiian Electric	3	79	79	/	443	5/17/241, 6/7/24 & 9/1/241	20 & 25	$	31.4
Hawaiian Electric	1	N/A	185	/	565	12/19/23	20	24
Self-build
Maui Electric	1		40	/	160	11/30/26		—
Total	5	79	304	/	1,168			$	55.4

1 Project delays have resulted in guaranteed commercial operations date being missed.

The total projected annual payment of $55.4 million for these PPAs will be recovered through the PPAC to the extent such costs are not included in base rates.

Tariffed renewable resources.

•As of March 31, 2026, there were approximately 736 MW, 157 MW and 162 MW of installed distributed renewable solar energy technologies at Hawaiian Electric, Hawaii Electric Light and Maui Electric, respectively, for tariff-based private customer generation programs, namely Standard Interconnection Agreement, Net Energy Metering, Net Energy Metering Plus, Customer Grid Supply, Customer Self Supply, Customer Grid Supply Plus, Interim Smart Export, Smart Distributed Energy Resources — Export, Smart Distributed Energy Resources — Non-Export, and Community-Based Renewable Energy. As of March 31, 2026, an estimated 44% of single-family homes on the islands of Oahu, Hawaii and Maui have installed private rooftop solar systems, and approximately 24% of the Utilities’ total customers have solar systems.

•The Utilities’ feed-in tariff program is designed to encourage the addition of more renewable energy projects in Hawaii. As of March 31, 2026, there were 44 MW, 2 MW and 6 MW of installed feed-in tariff capacity from renewable energy technologies at Hawaiian Electric, Hawaii Electric Light and Maui Electric, respectively.

Biofuel sources.

•On August 23, 2024, the Utilities issued an RFP for biodiesel fuel supply commencing February 1, 2026. Proposals were due on September 30, 2024, and the Utilities have completed negotiations with two suppliers and submitted an application to the PUC on April 3, 2025. On June 2, 2025, the Utilities and Pacific Biodiesel Technologies, LLC (PBT) signed an agreement for supply of biodiesel commencing February 1, 2026, which was approved by the PUC on January 14, 2026.

•On June 30, 2021, the Utilities issued an RFP for all fuels, including biodiesel, for supply commencing January 1, 2023. On December 13, 2021, the Utilities and PBT signed an agreement for supply of biodiesel on all islands commencing January 1, 2023, which was approved by the PUC on December 1, 2022. Hawaiian Electric also has a spot buy contract with PBT to purchase additional quantities of biodiesel at or below the price of diesel. Some purchases of “at parity” biodiesel have been made under the spot purchase contract, which was extended through June 2026.

•Hawaiian Electric has a contingency supply contract with REG Marketing & Logistics Group, LLC to also supply biodiesel to any generating unit on Oahu in the event PBT is not able to supply necessary quantities. This contingency contract has been extended to November 2026 and will continue with no volume purchase requirements.

Requests for renewable proposals, expressions of interest, and information.

•The Hawaii Island Stage 3 RFP, seeking 325 gigawatt-hours (GWh) per year of energy and 65 MW of renewable firm capacity, was issued on November 21, 2022. Proposals were received on April 20, 2023. The Stage 3 RFPs for Oahu and Maui opened for bids on January 20, 2023. For Oahu, the Utilities sought 500 to 700 MW of renewable firm capacity, and at least 965 GWh of renewable dispatchable energy annually. For Maui, the Utilities sought at least 40 MW of renewable firm capacity, and at least 425 GWh of renewable dispatchable energy annually. Proposals for the firm generation portion of the Maui Stage 3 RFP were received on August 17, 2023, and Priority List selections were announced on October 9, 2023. Contracts for three paired PV with storage projects have been executed and filed with the PUC for approval. On April 21, 2025, the PUC dismissed the three applications without prejudice and directed that new applications be filed upon completion of the respective Interconnection Requirement Study. A contract for a firm generation project on Maui was executed and filed with the PUC for approval on September 26, 2025. On November 12, 2025, the PUC suspended the firm generation project’s docket to address the applicability of Hawaii Revised

Statutes Chapter 343 (Hawaii Environmental Policy Act) to the project. The Utilities filed an amended and restated contract on March 11, 2026, and the PUC unsuspended the docket on March 25, 2026. In addition, in 2025, two solar-plus storage projects on Oahu, and one solar-plus project on Maui were filed with the PUC for approval. Negotiations for the remaining projects are ongoing.

On March 28, 2025, the Utilities filed an application to the PUC for their self-build project - Waiau repower project. The Utilities requested, among other things, approvals of 1) the commitment of funds for such project, and 2) recovery of project costs through the EPRM. On October 17, 2025, the Utilities filed an updated application reflecting revised costs of $1.16 billion, citing unavoidable and changed market conditions outside the Utilities’ control. On March 23, 2026, the PUC approved the commitment of funds and EPRM recovery for the Waiau repower project at the initial estimated cost of $847 million plus the lesser of a 10% increase or the difference in the GDPPI between the date of the best and final offer submission and the date of the PUC’s decision and order (Inflationary Adjustment). On April 2, 2026, the Utilities filed a motion for reconsideration of the PUC’s decision and order. On April 17, 2026, the PUC issued an order addressing the Utilities’ motion for reconsideration which, among other things, affirmed that the project costs up to $847 million plus the Inflationary Adjustment can be recovered through EPRM and clarified that the Utilities may, after the project is in-service, seek recovery for project cost amounts greater than the approved amount in a general rate case or rate re-basing proceeding. Based on the estimated GDPPI for the first quarter of 2026 released by the Bureau of Economic Analysis on April 30, 2026, the project costs plus the Inflationary Adjustment are currently estimated at $908 million. See also “Utility projects” in Note 4 of the Condensed Consolidated Financial Statements.

A summary of the Stage 3 PPAs and self-build project is as follows:


Utilities	Number of contracts	Total photovoltaic size (MW)	BESS Size (MW/MWh)	Firm Generation (MW)
PPAs
Hawaiian Electric	4	126	510	307
Hawaii Electric Light	3	86	374	60
Maui Electric	4	90	240	40

Hawaiian Electric	1	—	—	253
Total	12	302	1,124	660

•On August 19, 2024, the PUC opened a docket for the Utilities’ Integrated Grid Planning RFP (IGP RFP). On August 26, 2024, the Utilities filed their draft IGP RFP for Oahu and Hawaii Island. The Oahu portion of the IGP RFP seeks 750 GWh per year of energy and 350 MW of grid forming resources by November 1, 2030, and 81 MW of renewable firm capacity by December 2033. The Hawaii Island portion of the IGP RFP seeks 435 GWh per year of energy and 115 MW of grid forming resources by November 1, 2030, and 30 MW of renewable firm capacity by December 2032. On August 18, 2025, the Utilities filed a request with the PUC for approval to not offer utility-owned sites to other potential bidders. On September 9, 2025, the Consumer Advocate filed a response indicating it did not object to the Utilities’ request and a party to the docket filed a response requesting that the PUC consider the broader market impacts that limiting available sites would have on the available interconnection capacity and market competitiveness. On December 12, 2025, and on February 6, 2026, the Utilities filed their responses to additional PUC information requests.

Legislation and regulation. Congress and the Hawaii legislature periodically consider legislation that could have positive or negative effects on the Utilities and their customers. Also see “Environmental regulation” in Note 4 of the Condensed Consolidated Financial Statements.

Legislation. On June 6, 2025, Act 191 was signed into law, which allows the State to “step-in” for the Utilities in the case of utility financial distress, ensuring project owners receive payment, addressing concerns of some independent power producers’ ability to procure low-cost financing for new renewable energy and storage projects due to the Utilities’ credit ratings. On July 1, 2025, Act 258 was signed into law, which directs the PUC to study the viability of a wildfire relief fund, establish an aggregate liability cap on economic damages from future wildfires and authorizes securitization to finance wildfire safety and resilience infrastructure improvements. On July 8, 2025, Act 301 was signed into law, which appropriates funds to address the State of Hawaii’s share in the settlement of claims related to the Maui wildfire and windstorm tort litigation settlement. Act 258 is expected to help support the Utilities’ financial stability to move forward, while Act 301 provides a resolution to those affected by the Maui windstorm and wildfires and provides assurance for a global settlement to move

forward. Act 191 supports the Utilities’ ability to procure energy and gives IPP’s assurance to bid on projects in order to provide customers and communities with safe, reliable and affordable clean energy.

As noted above, on July 2, 2025, Act 266 was signed into law. Among other things, Act 266 authorizes wheeling of renewable energy and requires the PUC to establish policies and procedures to implement wheeling of renewable electricity for a capacity of not more than two megawatts, as well as microgrid service tariffs, by January 1, 2027. Act 266 also requires the PUC to establish an installation goal for new customer-sited distributed energy resources and establish tariffs to achieve the installation goal and for grid service programs, microgrids, and community-based renewable energy. The Utilities are currently assessing the potential impact related to wheeling as the PUC works to establish the provisions and terms for the implementation of wheeling in compliance with Act 266. For more information on wheeling, see discussion in “Investigation on the establishment of wheeling” above.

The One Big Beautiful Act signed into law on July 4, 2025 may impact the ability of the Utilities’ recently selected and new wind and solar projects to qualify for federal tax credits. Regulations continue to be developed, so the complete scope of potential impacts remains unknown at this time. Any loss in renewable energy tax credits could lead to project risk for new wind and solar projects in development and will likely result in higher prices for such projects, developers of which rely extensively on federal tax credits to finance such projects. It is also possible that the sunsetting of these tax credits will impact the supply chain for projects throughout the U.S. as developers rush to meet the four-year safe harbor timeline. The legislature is expected to consider legislation to provide a state tax credit to fill the void left by the expiration of the federal solar tax credit. However, due to budget shortfalls, the likelihood of its passage is limited.

Trade policies. Impacts to the Utilities from trade policies imposed by the U.S. or its trading partners are uncertain at this time. The Utilities estimated that in 2024, more than 90% of the Utilities’ capital goods were domestically sourced. However, the Utilities and their independent power producers procure capital goods that flow through global supply chains and may include raw materials, sub-components, or components sourced or assembled outside the U.S. Utility capital costs and the cost of power procured from independent power producers may increase due to new trade policies and changes in trade policy from the U.S. and its trading partners, based on the amount of foreign content of capital goods. It is also possible that trade policies could impact commodities and raw materials costs, leading to inflation of utility capital costs indirectly through the broader supply chain. Utility-scale battery projects planned by both Hawaiian Electric and independent power producers may see significant cost increases or supply chain challenges, as the majority of battery components are currently manufactured in, or have significant supply chain exposure to, the People’s Republic of China. The Utilities are still assessing the potential impact of current trade policies.

Federal grant. On August 7, 2024, the Utilities received a notification from the U.S. Department of Energy that their Climate Adaption Transmission and Distribution Resilience Program (Resilience Program) application for $95 million in federal funds was officially awarded. In 2025, President Trump issued multiple executive orders that impact federal funding. The Utilities are not impacted at this time but will continue to monitor for any new executive orders and any changes that are passed down through the federal contracting officer for the Resilience Program. See “Utility projects” in Note 4 of the Condensed Consolidated Financial Statements for additional discussions. There is no assurance that the federal government will reimburse in a timely manner or may dispute reimbursement.

Fuel contracts. On June 30, 2021, the Utilities issued two RFPs for all fuels for supply commencing January 1, 2023. On February 1, 2022, the Utilities and PAR Hawaii Refining, LLC (PAR Hawaii) entered into a fuel supply contract (Supply Agreement) commencing January 1, 2023. On December 1, 2022, the PUC issued a D&O approving the PAR Hawaii fuels contract and recovery of associated costs through ECRC. On August 14, 2024, the Utilities entered into a second amendment of the Supply Agreement. The second amendment extends the term of the Supply Agreement by additional three years and creates savings in fuel costs. The second amendment became effective on June 18, 2025, upon the issuance of the final D&O by the PUC.

On March 3, 2022, as part of economic sanctions amid the Russia-Ukraine war, PAR Hawaii announced that it was suspending all purchases of Russian crude oil, which accounts for at least 25% of Hawaii’s supply. The Utilities are taking additional measures to ensure adequate supply of fuel by entering into a backup fuel supply contract with Vitol Inc. (Vitol) commencing on December 1, 2022 through June 30, 2023, with annual extensions if mutually agreed by both parties. The fuel supply contract was extended to June 30, 2026. The PUC issued the final D&O approving the Vitol backup fuels supply contract on December 1, 2022, and the costs incurred under the contract with Vitol are recovered in the Utilities’ respective ECRCs.

FINANCIAL CONDITION

Liquidity and capital resources. As discussed in Note 2 of the Condensed Consolidated Financial Statements,

HEI’s and the Utilities’ future results of operations involve significant risks and uncertainties. Factors that could affect HEI’s and the Utilities’ future operating results and could cause actual results to vary materially from expectations include, but are not limited to, access to capital, ability to attract and retain key personnel, and pending or threatened litigation (including recent litigation noted below). HEI and Hawaiian Electric expects the payments under the Settlement Agreement will be made in four equal annual installments as allowed by the Settlement Agreements. See “Liquidity and capital resources” in HEI’s MD&A for additional information.

HEI’s and the Utilities’ future results of operations involve significant risks and uncertainties. Factors that could affect HEI’s and the Utilities’ future operating results and could cause actual results to vary materially from expectations include, but are not limited to, access to capital, ability to attract and retain key personnel, and pending or threatened litigation. Although the Utilities have a fuel pass-through mechanism with limited fuel cost-risk sharing, the Utilities expect cash flow impacts from the timing of the disbursements for fuel inventories and delayed collection of accounts receivable, resulting in higher working capital requirements.

Hawaiian Electric’s objective continues to be to operate a strong, financially healthy enterprise to empower a thriving future for Hawaii. While the fundamentals of their business remain strong, the Utilities took prudent and measured actions to strengthen their financial position while continuing to provide reliable service to their customers and reinforcing their commitment to serving the community for the long term. On September 5, 2025, HEI and Hawaiian Electric each entered into a fourth amended and restated credit agreement with a syndicate of eight financial institutions, increasing each of their committed capacities to $300 million (see Note 5 of the Condensed Consolidated Financial Statements). Longer term, the Utilities entered into an asset-based credit facility that allows borrowing up to $250 million (see Note 5 of the Condensed Consolidated Financial Statements) and are also evaluating other sources of liquidity that could include securitization, re-prioritizing capital spending and reducing O&M, issuing unsecured debt, and conducting asset sales, among others.

The following table provides the components of available liquidity under existing facilities.


	As of March 31, 2026
(in millions)	Capacity		Outstanding		Undrawn
Unsecured revolving line of credit	$	300	$	—	$	300
ABL Facility	218		—		218
Borrowing from HEI - standing commitment letter	75		—		75

Total credit	$	593	$	—	$	593



Cash and cash equivalents					437
Total available liquidity from cash and under existing facilities					$	1,030

As of March 31, 2026, Hawaii Electric Light and Maui Electric had short-term borrowings from Hawaiian Electric in the amount of nil and $10 million, respectively, and had long-term intercompany loans from Hawaiian Electric in the amount of $25 million and $90 million, respectively.

See Note 5 of the Condensed Consolidated Financial Statements for a brief description of Hawaiian Electric’s loans.

Management believes that HEI’s and the Utilities’ current cash and cash equivalents balances, as of March 31, 2026, amounting to $9.6 million and $436.8 million, respectively, the available capacity on Hawaiian Electric’s ABL Facility and revolving line of credit (see Note 5 of the Condensed Consolidated Financial Statements), and the additional liquidity from HEI’s at-the-market offering program, provide sufficient liquidity to fund operations and satisfy their other obligations for the short term.

As of March 31, 2026, the Utilities are in compliance with all applicable financial covenants and expect to continue to be in compliance with all the financial covenants in the next 12 months. The Utilities’ liquidity has improved, but continues to be impacted from the downgrades of their credit ratings, which result in higher credit spreads compared to investment grade credit spreads. However, the Utilities cannot predict the future effects on the Utilities’ ability to access additional capital or the future impacts on the Utilities’ financial position, results of operations, and cash flows.

The rebuilding of Lahaina will be a community-led effort and will occur over an extended period of time. The cost of rebuilding Maui Electric’s infrastructure is not yet known, but could be significant because the infrastructure that may be required is expected to be different than what previously existed. For example, to mitigate wildfire risk, grid hardening

strategies, such as undergrounding of lines in high-risk locations will be significantly more expensive than using overhead lines and will thus result in increased costs.

Hawaiian Electric utilizes cash on hand to support normal operations and will draw on its revolving line of credit or ABL Facility, as needed, to supplement any operational needs. Hawaiian Electric may also borrow short-term from HEI for itself and on behalf of Hawaii Electric Light and Maui Electric, and Hawaiian Electric may borrow from or loan to Hawaii Electric Light and Maui Electric on a short-term basis. The intercompany borrowings among the Utilities, but not the borrowings from HEI, are eliminated in the consolidation of Hawaiian Electric’s financial statements. The Utilities also utilize long-term debt, borrowings of the proceeds of special purpose revenue bonds issued by the State of Hawaii Department of Budget and Finance, the issuance of privately placed unsecured senior notes bearing taxable interest, and high yield capital markets, to finance the Utilities’ capital improvement projects, or to repay short-term borrowings used to finance such projects. The downgrades of Hawaiian Electric’s credit ratings will continue to adversely impact the Utilities’ ability to access lower cost sources of capital.

Credit ratings. On March 17, 2026, S&P revised Hawaiian Electric’s outlook to “Positive” from “CreditWatch Positive” and reaffirmed the “B+” issuer credit rating. On April 21, 2026, Moody’s upgraded Hawaiian Electric’s long-term issuer and senior unsecured rating to “Ba1” from “Ba2,” and changed its outlook to “Stable” from “Positive.”

Taxable debt. On July 24, 2025, the Utilities received PUC approval to issue during the three-year period of 2025 through 2027, unsecured obligations bearing taxable interest (Hawaiian Electric up to $900 million, Hawaii Electric Light up to $115 million and Maui Electric up to $150 million), to finance capital expenditures, repay long-term and/or short-term debt used to finance or refinance capital expenditures, and/or to reimburse funds used for payment of capital expenditures. Pursuant to the approval, on September 18, 2025, Hawaiian Electric issued $500 million in unsecured senior notes with an interest rate of 6.00%. A portion of the proceeds was used to repay the outstanding balance of the Utilities’ revolving and term loan facilities and the remaining proceeds are intended to be used to 1) finance capital expenditures, 2) repay long-term debt and short-term debt used to finance or refinance capital expenditures, and 3) reimburse funds used for the payment of capital expenditures. The 2025 Notes will mature on October 1, 2033.

On November 3, 2025, Hawaiian Electric made long-term intercompany loans to Hawaii Electric Light and Maui Electric in the amount of $25 million and $90 million, respectively. The interest rate and term of the loans are the same as Hawaiian Electric’s 2025 Notes. The long-term intercompany loans are eliminated in the total consolidated Hawaiian Electric amounts. See summary table below for remaining authorized amounts as of March 31, 2026 for each respective utility.


(in millions)	Hawaiian Electric		Hawaii Electric Light		Maui Electric
Total “up to” amounts of taxable debt authorized from 2025 through 2027	$	900	$	115	$	150
Less: taxable debt executed on September 18, 2025/ long-term intercompany loans	500		25		90
Remaining authorized amounts	$	400	$	90	$	60

As of March 31, 2026, the Utilities have $2.18 billion of long-term debt, of which $125 million is due or expected to be repaid within 12 months.

Equity. On October 28, 2025, the Utilities received PUC approval to issue and sell each utility’s common stock over a three-year period from January 1, 2025 through December 31, 2027 (Hawaiian Electric sale/s to HEI of up to $210 million, Hawaii Electric Light sale/s to Hawaiian Electric of up to $70 million, and Maui Electric sale/s to Hawaiian Electric of up to $145 million) and the purchase of Hawaii Electric Light and Maui Electric common stock by Hawaiian Electric. As of March 31, 2026, no common stock has been issued under this authorization.

Cash flows. The following table reflects the changes in cash flows for the three months ended March 31, 2026 compared to the three months ended March 31, 2025:


	Three months ended March 31
(in thousands)	2026		2025		Change
Net cash provided by operating activities	$	64,923	$	79,014	$	(14,091)
Net cash used in investing activities	(101,543)		(84,146)		(17,397)
Net cash used in financing activities	(12,791)		(48,590)		35,799

Net cash provided by operating activities. The decrease in net cash provided by operating activities was primarily driven by higher cash paid for maintenance and storm response costs and higher cash paid for fuel oil stock due to higher volume purchased.

Net cash used in investing activities. The increase in net cash used in investing activities was primarily driven by an increase in capital expenditures related to construction activities.

Net cash used in financing activities. The decrease in net cash used in financing activities was largely driven by repayment of the revolving credit facility in 2025.

Material cash requirements. Material cash requirements of the Utilities include payments related to settlement of tort-related legal claims and cross claims to the extent HEI does not make such payments, O&M expenses, labor and benefits costs, fuel and purchase power costs, debt and interest payments, operating and finance lease obligations, their forecasted capital expenditures (including capital expenditures related to wildfires and wildfire mitigations) and investments, their expected retirement benefit plan contributions and other short-term and long-term material cash requirements. The cash requirements for O&M, fuel and purchase power costs, debt and interest payments, and operating and finance lease obligations are generally funded through the collection of the Utilities’ revenue requirement established in the last rate case and other mechanisms established under the regulatory framework. The cash requirements for capital expenditures are generally funded through operating cash flows, the issuance of debt, and contributions of equity from HEI and generally recovered through the Utilities’ revenue requirement or other capital recovery mechanisms over time.

Hawaiian Electric’s consolidated capital structure was as follows:


(dollars in millions)	March 31, 2026			December 31, 2025

Long-term debt, net, including current portion of long-term debt, net	$	2,183	58%	$	2,183	58	%

Common stock equity	1,609		42	1,583		42
	$	3,792	100%	$	3,766	100	%

The Utilities’ credit rating downgrades related to the Maui windstorm and wildfires will continue to limit their ability to readily access low-cost sources of capital. Through the sale of common stock in September 2024, HEI has raised sufficient cash to pay the first installment of the settlement of wildfire tort claims and paid the first installment on April 10, 2026. HEI is currently working with its financial advisors on a financing plan to raise the additional capital required to fund the remaining settlement payments for the wildfire tort claims. While management believes that HEI will be able to raise the necessary capital, there is no assurance that management’s plans will be successful. The damages and losses related to the Maui windstorm and wildfires and related lawsuits (see further information in Note 2 of the Condensed Consolidated Financial Statements), the economic impact of higher fuel prices, inflation, higher interest rates, tightening of monetary policy, and geopolitical situations, create significant uncertainty, and the Utilities cannot predict the extent or duration of these conditions, the future effects that these conditions will have on the Utilities’ financing plan, cost of capital and their ability to access additional capital, or the future impacts on the Utilities’ financial position, results of operations, and cash flows.
