HE US Equity☆

ITEM 1A. RISK FACTORS

The businesses of HEI and its subsidiaries involve numerous risks which, if realized, could have a material and adverse effect on the Company’s financial statements. For additional information for certain risk factors enumerated below and other risks of the Company and its operations, see “Cautionary Note Regarding Forward-Looking Statements” above and HEI’s MD&A, HEI’s “Quantitative and Qualitative Disclosures about Market Risk,” the Notes to the Consolidated Financial Statements, Hawaiian Electric’s MD&A and Hawaiian Electric’s “Quantitative and Qualitative Disclosures About Market Risk.”

Holding company and company-wide risks.

Losses resulting from the Maui windstorm and wildfires did and may continue to have a material adverse effect on HEI’s and Hawaiian Electric’s financial condition, liquidity, cash flows and results of operations. 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 Department of Fire and Public Safety and Bureau of Alcohol, Tobacco, Firearms and Explosives reports classified the cause of the fire as “accidental.”

Effective November 1, 2024, HEI and Hawaiian Electric entered into the Settlement Agreements (as defined herein) to settle the tort-related legal claims in the litigation arising out of the Maui windstorm and wildfires. One of the Settlement Agreements, the Class Settlement Agreement (as defined herein) remains subject to final court approval.

HEI and Hawaiian Electric have agreed to make substantial payments to settle all Maui windstorm and wildfire tort-related legal claims if all conditions of the Settlement Agreements are satisfied. 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 for the One ‘Ohana Initiative (a humanitarian aid fund to provide payments outside of litigation to the beneficiaries of those who died, as well as compensation for personal injury damages). 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, with the first installment expected to be made once the conditions to funding are satisfied, which will occur no sooner than early 2026. 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 the settlements.

If all conditions of the Settlement Agreements are satisfied, HEI expects to finance the settlement payments through a mix of debt, common equity, equity-linked securities or other potential options. While HEI management believes it will be able to raise the capital necessary to finance the settlement payments, there is no assurance that future financing will be available in sufficient amounts, on a timely basis or on reasonable terms acceptable to HEI, if at all.

If HEI’s financing plans are unsuccessful, HEI and Hawaiian Electric may need to consider other strategic alternatives, including delaying strategic initiatives, selling assets, or other strategic measures including, without limitation, obtaining relief under the U.S. Bankruptcy Code. Such alternatives could adversely affect our financial results or other factors impacting our finances, operations or HEI’s stock valuation.

The Settlement Agreements do not resolve claims with insurers who have asserted subrogation claims in separate lawsuits, and such insurers are not parties to the Settlement Agreements, but resolution of their claims through an agreement or a final unappealable court order is a condition to the defendants’ payment obligations under the Settlement Agreements. Two primary subrogation actions have been 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 have now appealed those rulings. No briefing schedules in these appeals have been set.

If the conditions of the Settlement Agreements are not satisfied or the agreements are otherwise terminated, HEI and Hawaiian Electric intend to vigorously defend against the litigation. There is no assurance that HEI and Hawaiian Electric will be successful in the defense of the litigation or that insurance proceeds will be available to fund any potential settlements, judgments, or costs associated with the litigation.

There can be no assurance that HEI and Hawaiian Electric will have the liquidity to make the payments required under the Settlement Agreements. The amount of any liability arising from the Maui windstorm and wildfires could have a material adverse impact on our financial condition, liquidity, cash flows and results of operations.

HEI’s and Hawaiian Electric’s access to lower cost sources of capital will continue to be negatively impacted as a result of the downgrades in their debt credit ratings to below investment grade. In August 2023, HEI and Hawaiian Electric received

15

multiple downgrades to their debt, including to ratings below investment grade, by Fitch, Moody’s and S&P. As of February 17, 2026, the Fitch, Moody’s and S&P ratings of HEI and Hawaiian Electric were as follows:

Fitch Moody’s S&P

HEI:

Outlook Positive Positive Watch Positive

Hawaiian Electric:

Long-term issuer default, long-term and issuer credit, respectively BB- Ba2 B+

Senior unsecured debt/special purpose revenue bonds BB Ba2 *

Cumulative preferred stock (selected series) * WR1 *

Outlook Positive Positive Watch Positive

1 Rating withdrawn due to preferred stock redemption in the fourth quarter of 2025.

* Not rated.

NP - Not Prime

WR - Withdrawn rating

Note: The above ratings reflect only the view, at the time the ratings are issued or affirmed, of the applicable rating agency, from whom an explanation of the significance of such ratings may be obtained. Such ratings are not recommendations to buy, sell or hold any securities; such ratings may be subject to revision or withdrawal at any time by the rating agencies; and each rating should be evaluated independently of any other rating.

Unless and until these debt ratings are upgraded to investment grade, the Company will continue to have restricted access to lower cost sources of capital. Recent projects, such as, wildfire mitigation plan, grid modernization, reliability and resilience all require significant capital expenditures to implement. The Company may not be able to obtain the necessary financing to achieve its business objectives as a result of the downgrades. Accordingly, the Company’s financial condition, liquidity, cash flows and results of operations may be adversely impacted if debt credit ratings are maintained at below investment grade for an extended period of time.

HEI’s and Hawaiian Electric’s credit ratings only reflect the view, at the time the ratings are issued, of the applicable rating agency. There is no assurance that any such credit rating will remain in effect for any given period of time or that such rating will not be lowered, suspended or withdrawn entirely by the applicable rating agency if, in such rating agency’s judgment, circumstances, such as current, past or future effects or events so warrant. Any such lowering, suspension or withdrawal of any rating may have an adverse effect on the availability of capital to the Company or the market price or marketability of HEI’s and/or Hawaiian Electric’s securities, which could increase the cost of capital of HEI and Hawaiian Electric, and such increased costs, including interest charges, under HEI’s and/or Hawaiian Electric’s debt securities and credit facilities, would result in reductions in HEI’s consolidated net income in future periods. Because HEI’s and Hawaiian Electric’s credit ratings were downgraded, HEI and Hawaiian Electric are unable to sell commercial paper and were required to draw on more expensive bank lines of credit and prioritize capital and other expenditures. Neither HEI nor Hawaiian Electric management can predict the duration of the downgrades and future rating agency actions or their effects on the future cost of capital of HEI or Hawaiian Electric. Such ratings are not recommendations to buy, sell or hold any securities; such ratings may be subject to revision or withdrawal at any time by the rating agencies; and each rating should be evaluated independently of any other rating.

Extreme weather events and other natural disasters, particularly those exacerbated by evolving climate dynamics such as the Maui windstorm and wildfires, could materially affect Hawaiian Electric’s assets and infrastructure, particularly if such infrastructure is damaged or is found to have contributed to other catastrophic events such as a wildfire. Extreme weather-related incidents and other natural disasters, including volcanic eruptions, mudslides, hurricanes, tsunamis and other storms, can interfere with the generation and transmission of electricity, and can seriously damage the infrastructure necessary to deliver electricity to customers. Damage to Hawaiian Electric’s infrastructure can also cause or contribute to additional loss through events such as wildfires. These risks are increasing, as evolving climate dynamics have exacerbated some of the conditions that lead to these extreme weather events and natural disasters. Such an event can result in lost revenue and increased expenses for the Utilities, but it also can result in regulatory penalties and disallowances if Hawaiian Electric is unable to restore power on a timely basis. Also, an extreme event can lead to significant claims for damages, including for loss of life and property, and has been the case with the Maui windstorm and wildfires. Therefore, these events could have a material adverse effect on the Company’s business, reputation, financial condition and results of operations.

16

Holding Company Risk—HEI is a holding company that derives its income from its principal operating subsidiary, Hawaiian Electric, and depends on the ability of Hawaiian Electric to pay dividends or make other distributions to HEI and on its own ability to raise capital. HEI is a legal entity separate and distinct from its subsidiaries. As a holding company, HEI’s cash flows and consequent ability to service its obligations and pay dividends on its common stock is dependent upon its receipt of dividends or other distributions from Hawaiian Electric and its ability to issue common stock or other equity securities and to incur additional debt. A material reduction or delay in dividends or other distributions by Hawaiian Electric for an extended period of time, such as a continuation or expansion of the reduction in dividends that HEI currently is experiencing due to the Maui windstorm and wildfires, could have a material adverse effect on the Company’s business, financial condition and results of operations. The ability of Hawaiian Electric to pay dividends or make other distributions to HEI, in turn, is subject to the risks associated with their operations and to contractual and regulatory restrictions, including:

•the provisions of an HEI agreement with the PUC (PUC Agreement), which could limit the ability of HEI’s principal electric public utility subsidiary, Hawaiian Electric, to pay dividends to HEI in the event that the consolidated common stock equity of the Utilities falls below 35% of total capitalization of the Utilities. As of December 31, 2025, the consolidated common stock equity of HEI’s electric utility subsidiaries was 42% of their total capitalization based on the current definition under the PUC Agreement and, as a result, the Utilities are restricted in cash payment of their dividend to HEI at this time (see Note 15 of the Consolidated Financial Statements.); and

•the provisions of debt instruments of HEI and its subsidiaries.

Credit and Capital Market Risk—The Company, and its lowered credit rating, is subject to risks associated with the Hawaii economy, including catastrophic events such as the Maui windstorm and wildfires (in the aggregate and on an individual island basis), volatile U.S. capital markets and changes in the interest rate and credit market environment that have or could result in higher retirement benefit plan funding requirements and restrictions on the ability of HEI or its subsidiaries to borrow money or issue securities. The two largest components of Hawaii’s economy are tourism and the federal government (including the military). Because the core businesses of HEI’s subsidiaries are providing local public electric utility services (through Hawaiian Electric and its subsidiaries), the Company’s operating results are significantly influenced by: Hawaii’s economy, which in turn is influenced by economic conditions in the mainland U.S. (particularly California) and Asia (particularly Japan) as a result of the impact of those conditions on tourism; by the impact of interest rates on the construction and real estate industries and by the impact of federal government spending in Hawaii, which can be affected by world conditions; and, from time to time, the expiration of federal government appropriations bills. In addition, the Hawaii economy could be directly or indirectly affected by implications and potential impacts of U.S. and foreign capital and credit market conditions and federal, state and international responses to those conditions and the potential impacts of global and local developments (including economic conditions and uncertainties; unrest, terrorist acts, wars (such as the Russia-Ukraine war), conflicts, political protests, deadly virus epidemic, pandemics, or other crisis; the effects of changes that have or may occur in U.S. policy, such as with respect to immigration and trade).

Changes in the U.S. capital markets can also have significant effects on the Company. For example, pension funding requirements are affected by the market performance of the assets in the master pension trust maintained for pension plans, and by the discount rate used to estimate the service and interest cost components of net periodic pension cost and value obligations. The Utilities’ pension tracking mechanisms help moderate pension expense; however, a significant reduction in the discount rate or in the value of the Company’s defined benefit pension plan assets could result in a substantial increase in the gap between the projected benefit obligations under the plans and the value of plan assets, resulting in increases in funding requirements.

HEI and the Utilities are also exposed to interest rate risk primarily due to their periodic borrowing requirements, the discount rate used to determine pension funding requirements and the possible effect of interest rates on the Utilities’ rates of return. Interest rates are sensitive to many factors, including general economic conditions and the policies of government and regulatory authorities. HEI cannot predict future changes in interest rates, nor be certain that interest rate risk management strategies it or its subsidiaries have implemented will be successful in managing interest rate risk.

There may be future conditions or events that raise substantial doubt about our ability to continue as a going concern, and it is possible that any plan developed to alleviate such doubt may be unsuccessful. In addition, any capital raised may result in dilution to our current shareholders. For the year ended December 31, 2024, the Company incurred losses from continuing operations of approximately $1.32 billion. For the year ended December 31, 2024, the Utilities incurred net losses of approximately $1.23 billion. The net losses for the year ended December 31, 2024, were primarily due to the accruals of estimated wildfire liabilities in the second and third quarters of 2024, totaling approximately $1.92 billion related to the Maui windstorm and wildfire tort-related legal claims. The Company previously disclosed in its Quarterly Report on Form 10-Q for the quarter ending June 30, 2024, that based on its financial and liquidity condition, and because it had not yet implemented a capital financing plan to address proposed wildfire settlement payments, there was substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern. In the third quarter of 2024, the Company was able to alleviate the conditions that caused the substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern.

17

Management believes the Company’s cash and cash equivalents amount of $502 million and GLST1’s restricted cash amount of $479 million, both as of December 31, 2025, the available capacity on Hawaiian Electric’s asset-based lending facility (ABL Facility) (see Note 6 of the Consolidated Financial Statements included herein), additional liquidity under HEI’s registered at-the-market offering program as well as expenditure reduction efforts effectively alleviate any conditions that may cause substantial doubt regarding HEI’s and Utilities’ ability to continue as a going concern. The Company has adequate cash to meet its financial obligations and sustain operations in the short term, including available sufficient liquidity to fund the first installment of the settlement of wildfire tort claims (expected to be made no sooner than early 2026) and its other cash obligations for the next 12 months following the issuance of its financial statements. The plans that have been implemented have mitigated the conditions that previously caused the substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern as of the date of filing their 2024 second quarter financial statements. 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 of 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.

The recurrence of any substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern may affect the price of our common stock, may impact our relationship with third parties with whom the Company does business, including our vendors, lenders and employees, may impact our ability to raise additional capital or refinance existing debt and may impact our ability to comply, going forward, with certain covenants in our debt agreements and/or satisfy conditions to draw thereunder, which could significantly and materially restrict our operations.

If a court-approved definitive settlement agreement to resolve Maui windstorm and wildfire tort-related legal claims is not obtained, or if financing for settlement payments is not available, the Company may need to consider other alternatives for addressing the outstanding legal claims or settlement payments, and such alternatives could adversely affect our financial results or other factors impacting our finances, operations or stock valuation. As described more fully in Note 2 of the Consolidated Financial Statements included herein, the Company entered into Settlement Agreements effective November 1, 2024, to resolve all Maui windstorm and wildfire tort-related legal claims, including all claims among the defendants. Such Settlement Agreements are subject to court approval, and other conditions including resolution of the claims of the insurance companies that have paid claims for property loss and other damages. If all conditions of the Settlement Agreements are satisfied, the Company has agreed to make substantial payments to settle all Maui windstorm and wildfire tort-related legal claims. As described more fully in Note 2 of the Consolidated Financial Statements included herein, if the conditions of the Settlement Agreements are not satisfied or the agreements are otherwise terminated, the Company intends to vigorously defend against the litigation. There is no assurance that the Company will be successful in the defense of the litigation or that insurance proceeds will be available to fund any potential settlements, judgments, or costs associated with the litigation.

If all conditions of the Settlement Agreements are satisfied, the Company expects to finance the settlement payments through a mix of debt, common equity, equity-linked securities or other potential options. While management believes the Company will be able to raise the capital necessary to finance the settlement payments, there is no assurance that future financing will be available in sufficient amounts, on a timely basis or on reasonable terms acceptable to us, if at all.

If the Company’s financing plans are unsuccessful, the Company may need to consider other strategic alternatives, including delaying strategic initiatives, selling assets, or other strategic measures including, without limitation, obtaining relief under the U.S. Bankruptcy Code. Such alternatives could adversely affect our financial results or other factors impacting our finances, operations or stock valuation.

Shareholders of HEI’s common stock may experience future dilution as a result of future equity offerings. In order to raise additional capital, including capital necessary to fund litigation settlement expenses, the Company may in the future offer additional shares of HEI’s Common Stock or other securities convertible into or exchangeable for HEI Common Stock at prices that may not be the same as the current market price per share, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which the Company may sell additional shares of HEI Common Stock, or securities convertible or exchangeable into HEI Common Stock, in future transactions may be higher or lower than the current market price per share of HEI Common Stock.

In addition, any future sales of a substantial number of shares of HEI Common Stock in the public market, or the perception that such sales may occur, could adversely affect the price of HEI Common Stock. The Company cannot predict the effect, if any, that market sales of those shares of Common Stock, or the perception that those shares may be sold, will have on the market price of HEI Common Stock. Further, the Company may not have the ability to raise the amount of capital necessary on reasonable terms, or at all, to fund our contribution to the Maui wildfire tort litigation settlement, and uncertainties about the Company’s access to capital could have a material adverse effect on the market price of HEI Common Stock.

18

The Company does not expect to pay any dividends on HEI Common Stock in the foreseeable future. The Company does not currently intend to pay dividends on HEI Common Stock and currently intends to retain future earnings, if any, to fund the development and growth of the Company’s business and to fund future settlement payments of the tort-related legal claims in the litigation arising out of the Maui windstorm and wildfires. In addition, the terms of certain existing and any future debt agreements may preclude the Company from paying dividends on HEI Common Stock. As a result, capital appreciation, if any, of HEI Common Stock may be your sole source of gain for the foreseeable future.

Tax Legislation Risk—Adverse tax rulings or developments or changes in tax legislation could result in significant increases in tax payments and/or expense. Governmental taxing authorities could challenge a tax return position taken by HEI or its subsidiaries and if the taxing authorities prevail, HEI’s consolidated tax payments and/or expense, including applicable penalties and interest, could increase significantly. Additionally, changes in tax legislation or IRS interpretations could increase the Company’s tax burden and adversely affect the Company’s financial position, results of operations, and cash flows.

Geographic Concentration Risk—The Company is subject to the risks associated with the geographic concentration of its businesses and current lack of interconnections that could result in service interruptions at the Utilities. The business of the Utilities is concentrated on the individual islands they serve in the State of Hawaii. Their operations are more vulnerable to service interruptions than that of many U.S. mainland utilities because none of the systems of the Utilities are interconnected with the systems on the other islands they serve. Because of this lack of interconnections, it is necessary to maintain higher generation reserve margins than are typical for U.S. mainland utilities to help ensure reliable service. Service interruptions, including, in particular, extended interruptions that could result from a natural disaster or terrorist activity, could adversely impact the revenues and costs of some or all of the Utilities.

Competitive and Technological Risk—Increasing competition and technological advances could cause HEI’s businesses to lose customers or render their operations obsolete. Certain aspects of the electric utility industry are competitive. The success of HEI’s subsidiaries in meeting competition and responding to technological advances will continue to have a direct impact on HEI’s consolidated financial performance. For example:

•The Utilities face competition from customer self-generation, with or without cogeneration; customer energy storage; wheeling of renewable energy under Senate Bill 589, now known as Act 266, and the potential formation of community-based, cooperative ownership or municipality structures for electrical service on all islands it serves. With the exception of certain identified projects, the Utilities are required to use competitive bidding to acquire a future generation resource unless the PUC finds competitive bidding to be unsuitable. This means that unless exempt, proposed company-owned generation projects must be bid into a request for proposals which is open to IPPs, and be selected under a competitive bidding process. The PUC sets policies for distributed generation interconnection agreements and standby rates. The results of competitive bidding, customer self-generation, wheeling, and potential cooperative ownership or municipality structures for electric utility service, and the rate at which technological developments facilitating nonutility generation of electricity, combined heat and power technology, off-grid microgrids, and customer energy storage may render the operations of the Utilities less competitive or outdated and adversely affect the Utilities and the results of their operations.

Cybersecurity and Physical Security Risk—The Company’s information technology systems and operations could be impacted by a cyber incident, cybersecurity breach, or physical attack that could materially and adversely affect its businesses and reputation. The Company and its subsidiaries rely on information technology systems, some of which are managed or hosted by third party service providers, to manage its business data, communications, and other business processes. Such information technology systems are vulnerable to cyberattacks or other security incidents, which could result in unauthorized access to confidential data, ransomware demands or disruptions to operations. In addition, there is increasing cybersecurity risk associated with the broad adoption of a remote working environment. If the Company is unable to prevent or adequately respond to and resolve an incident, it may have a material impact on the Company’s business, financial condition, results of operations and reputation.

Utilities. The Utilities rely on evolving and complex operational systems and infrastructure and information systems, networks and other technologies, including artificial intelligence and machine learning, which are interconnected with the systems and network infrastructure owned by third parties to support a variety of business processes and activities, including procurement and supply chain, invoicing and collection of payments, customer relationship management, human resource management, the acquisition, generation and delivery of electrical service to customers, and to process financial information and results of operations for internal reporting purposes and to comply with regulatory financial reporting and legal and tax requirements. The Utilities use their systems and infrastructure to create, collect, store, and process sensitive information, including personal information regarding customers, employees and their dependents, retirees, and other individuals. Their systems are vulnerable to disability, failures or unauthorized access caused by natural disasters, physical attacks, cybersecurity incidents, security breaches, user error, unintentional defects created by system changes, military or terrorist actions, nation-

19

state threat actors, criminal organizations, power or communication failures or similar events. Any such failure could have a material adverse impact on the Utilities’ ability to process transactions and provide service, as well the Utilities’ financial condition and results of operations. Physical attacks targeting physical assets or personnel could cause damage, disrupt operations, or cause injuries. Any failure, interruption, or decrease in the functionality of the Utility’s operational networks could cause harm to the public or employees, significantly disrupt operations, negatively impact the Utility’s ability to operate in a safe and efficient manner, and damage the Utility’s assets or operations or those of third parties. Further, a data breach involving theft, improper disclosure, or other unauthorized access to or acquisition of confidential information could subject the Utilities to penalties for violation of applicable privacy laws, claims by third parties, and enforcement actions by government agencies. A data breach could also reduce the value of proprietary information, and harm the reputation of the Utilities.

Private and public entities, such as the North American Electric Reliability Corporation, and the U.S. federal government, including the Departments of Defense, Homeland Security and Energy, and the White House, have noted that cyberattacks targeting utility systems are increasing in sophistication, magnitude, and frequency. The Utilities’ systems have been, and will likely continue to be, a target of attacks. Further, the Utilities’ operational networks may be subject to unforeseen operational/cybersecurity risks due to the reliance on legacy operational components or modernizing and interconnecting existing infrastructure with new technologies and control systems, including those owned by third parties, such as independent power producers, distributed energy resource aggregators and customers. Although the Utilities have not experienced a material cybersecurity or physical security breach to date, such incidents may occur and may have a material adverse effect on the Utilities and the Company in the future. The Utilities continue to make investments in their cybersecurity and physical security programs, including personnel, technologies, cyber insurance and training of Utilities personnel; however, there can be no assurance that these systems or their expected functionality will be implemented, maintained, or expanded effectively; nor can security measures completely eliminate the possibility of a cybersecurity breach or physical attack. The Utilities maintain cyber liability insurance that covers certain damages caused by cyber incidents. However, there is no guarantee that adequate insurance will continue to be available at rates the Utilities believe are reasonable or that the costs of responding to, and recovering from, a cyber incident will be covered by insurance or recoverable in rates. If the Utilities’ operational technologies or networks were to malfunction or fail or cybersecurity or other security measures were to be breached, the Utilities could suffer financial loss, business disruptions, liability to customers, regulatory intervention or damage to their reputations.

Due to the size, scope and complexity of the Utilities’ business, the development and maintenance of information technology systems to process and track information is critical and challenging. The Utilities often rely on third-party vendors to host, maintain, modify, and update its systems and these third-party vendors could cease to exist, fail to establish adequate processes to protect the Utilities systems and information, experience supply chain compromises or other internal or external security incidents. In addition, the Utilities are pursuing complex business transformation initiatives, which include the implementation of new systems and the upgrade or replacement of existing systems. Significant system changes increase the risk of system interruptions, which may occur. Further, delay or failure to complete the integration of information systems and processes may result in delays in regulatory cost recovery, or the failure to realize the benefits anticipated to be derived from these initiatives.

The Utilities’ disaster recovery plans may not be successful in preventing the loss of customer data, service interruptions and disruptions to operations or damage to important facilities. If any of these systems fail to operate properly or become disabled and the Utilities’ disaster recovery plans do not effectively resolve the issues in a timely manner, the Utilities could suffer financial loss, business disruptions, liability to customers, regulatory intervention or damage to their reputations, any of which could have a material adverse effect on the Utilities’ and the Company’s financial condition and results of operations.

Uninsured Losses—HEI’s businesses could suffer losses that are uninsured due to a lack of affordable insurance coverage, unavailability of insurance coverage or limitations on the insurance coverage the Company does have. In the ordinary course of business, HEI and its subsidiaries purchase insurance coverages (e.g., property and liability coverages) to protect against loss of, or damage to, their properties and against claims made by third parties and employees for property damage or personal injuries. However, the protection provided by such insurance is limited in significant respects and, in some instances, there is no coverage. Some of the insurance coverages have substantial deductibles or have limits on the maximum amounts that may be recovered. In common with other companies in its line of business, the Utilities’ overhead and underground transmission and distribution systems (with the exception of substation buildings and contents), which have a replacement value roughly estimated at $14 billion, are largely not insured against loss or damage because the amount of transmission and distribution system insurance capacity is limited and the premiums are cost prohibitive. Similarly, the Utilities have no business interruption insurance as the premiums for such insurance would be cost prohibitive, particularly since the Utilities are not interconnected to other systems. If a hurricane or other uninsured catastrophic natural disaster were to occur, and if the PUC did not allow the affected Utilities to recover from ratepayers restoration costs and revenues lost from business interruption, the lost revenues and repair expenses could result in a significant decrease in HEI’s consolidated net income or in significant net losses for the affected periods.

20

Related to damages and costs incurred as a result of the Maui windstorm and wildfires, the Company has property insurance with a total policy limit of $500 million, subject to a $1 million retention, for wildfire damages related to Utility-owned non-generating assets, including overhead transmission and distribution assets within 1,000 feet of such assets. The Company also 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 $0.1 million, respectively, and $145 million directors and officers liability insurance to cover claims related to shareholder and derivative lawsuits, with a retention of $1.0 million. The aggregate damages and costs associated with the Maui windstorm and wildfires could significantly exceed the Company’s policy limits.

Environmental Regulation—Increased federal and state environmental regulation will require an increasing commitment of resources and funds and could result in construction delays or penalties and fines for non-compliance. HEI and its subsidiaries are subject to federal, state and local environmental laws and regulations relating to air quality, water quality, hazardous substances, waste management, natural resources and health and safety, which regulate, among other matters, the operation of existing facilities, the construction and operation of new facilities and the proper cleanup and disposal of hazardous and toxic wastes and substances. These laws and regulations could result in increased capital, operating, and other costs. HEI or its subsidiaries are currently involved in investigatory or remedial actions at current, former or third-party sites and there is no assurance that the Company will not incur material costs relating to these sites. In addition, compliance with these legal requirements requires the Utilities to commit significant resources and funds toward, among other things, environmental monitoring, installation of pollution control equipment, payment of emission fees and natural resource minimization and mitigation costs. These laws and regulations, among other things, require that certain environmental permits be obtained in order to construct or operate certain facilities, and obtaining such permits can entail significant expense and cause substantial construction delays. Also, these laws and regulations may be amended from time to time, including amendments that increase the burden and cost of compliance. For example, emission and/or discharge limits may be tightened, more extensive permitting requirements may be imposed and additional substances may become regulated. In addition, significant regulatory uncertainty exists regarding the impact of federal or state greenhouse gas emission limits and reductions.

If HEI or its subsidiaries fail to comply with environmental laws and regulations, even if caused by factors beyond their control, that failure may result in civil or criminal penalties and fines or the cessation of operations that could have a material adverse on the Company’s financial condition or results of operations.

Electric utility risks.

The following risks are generally specific to Hawaiian Electric, but could have a material adverse effect on the Company’s consolidated results of operations, financial condition and liquidity.

Regulatory Risk—Actions of the PUC are outside the control of the Utilities and could result in inadequate or untimely rate increases, rate reductions or refunds or unanticipated delays, expenses or writedowns in connection with the construction of new projects. The rates the Utilities are allowed to charge for their services and the timeliness of permitted rate increases are among the most important items influencing the Utilities’ results of operations, financial condition and liquidity. The PUC has broad discretion over the rates that the Utilities charge their customers. On December 23, 2020, as part of the D&O establishing the PBR Framework, the PUC established a five-year Multi-year Rate Period (MRP) during which there will be no general rate cases. In the fourth year of the MRP, the PUC began its comprehensive review of the PBR Framework to determine if any modifications or revisions are appropriate. 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. This alternative could be implemented by January 2027. If a satisfactory non-rate case re-basing alternative cannot be achieved, the Utilities would file a rate case in the second half of 2026, utilizing a 2027 test year.

Any adverse decision by the PUC concerning the level or method of determining electric utility rates at the end of the MRP, including the items and amounts that may be included in rate base, the returns on equity or rate base found to be reasonable, the potential consequences of exceeding or not meeting such returns, the denial of exceptional project recovery applications during the MRP, adverse impact of adjustments made to the PBR Framework, decisions on recovery of exogenous items under the PBR Framework, or any prolonged delay in rendering a decision in a rate or other proceeding could have a material adverse effect on Hawaiian Electric’s consolidated results of operations, financial condition and liquidity.

To improve the timing and certainty of cost recovery, the Utilities have received approval of various recovery mechanisms, including an ECRC (which includes a PUC-ordered 98%/2% risk-sharing split between customers and the Utilities for fossil fuel price variations from baseline prices, with a current annual aggregate exposure cap of +/- $3.7 million), a PPAC, and pension and OPEB tracking mechanisms, as well as a decoupling mechanism, an exceptional project recovery mechanism (EPRM) (formerly Major Project Interim Recovery (MPIR) adjustment mechanism), and a Renewable Energy Infrastructure Program surcharge. Any modification or elimination of these cost recovery mechanisms could have a material adverse effect on the Utilities. See “Regulatory mechanisms” in Electric utility’s Business.

Under the PBR Framework, the Utilities’ annual revenue adjustment (ARA) includes a customer dividend consisting of a negative adjustment of 0.22% compounded annually and a flow through of the “pre-PBR” savings commitment from the management audit recommendations developed in the 2020 test year rate case. The ability of the Utilities to recover increasing costs and earn a reasonable return on capital investments not covered by the ARA or not achieving the customer dividend and cost savings commitment could have a material adverse effect on the Utilities. In addition, several existing Performance Incentive Mechanisms (PIMs) remain in effect. The PUC has indicated that in the next phase of PBR review, it will examine modifications to the I-factor and the customer dividend provisions of the ARA, the earnings sharing mechanism, revenue opportunities from the X-factor and the EPRM guidelines, and the PIM portfolio. The assessment of penalties for not achieving performance goals or the failure to achieve PIMs rewards could affect the Utilities’ ability to achieve their allowed ROACEs and also have a material adverse effect on the Utilities.

Related to the Maui windstorm and wildfires, the Utilities obtained PUC approval to defer certain non-labor expenses incurred from August 8, 2023 through December 31, 2025 that are not already a part of base rates. 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. Additionally, 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. See “Performance-based regulation framework” and “Regulatory assets for Maui windstorm and wildfires related costs” in Note 4 of the Consolidated Financial Statements.

Based on the current operations of the Utilities and regulatory framework, including the impact of the approved PBR Framework, the Utilities continue to follow regulatory accounting under Accounting Standards Codification (ASC) 980. Continued accounting in this manner requires that certain criteria relating to the recoverability of such costs through rates be met, including achieved financial results that support the recovery of costs. If events or circumstances change, such that the criteria are no longer satisfied, the Utilities expect that their regulatory assets (amounting to $308 million as of December 31, 2025), net of regulatory liabilities (amounting to $1,444 million as of December 31, 2025), would be charged to the statement of income in the period of discontinuance. See “Performance-based regulation framework” in Note 4 of the Consolidated Financial Statements.

The Utilities could be required to refund, with interest, any revenues collected from customers under interim rate orders in their rate case proceedings and other proceedings that exceed the amounts approved in final orders.

Many public utility projects require PUC approval and various permits (e.g., environmental and land use permits) from other governmental agencies. Difficulties in obtaining, or the inability to obtain, the necessary approvals or permits, or any adverse decision or policy made or adopted, or any prolonged delay in rendering a decision, by an agency with respect to such approvals and permits, can significantly increase project costs or lead to project cancellation. In the event a project does not proceed, or if the PUC disallows cost recovery for all or part of a project, or if project costs exceed caps imposed by the PUC in its approval of the project, project costs may need to be written off in amounts that could result in significant reductions in Hawaiian Electric’s consolidated net income. In addition, as the Utilities may retire fossil fuel generating units before fully recovering of its investment and the PUC disallows recovery of undepreciated costs, the resulting write-offs could have an adverse impact on the Utilities’ results of operations.

Weather Conditions Risk—Electric utility operations are significantly influenced by weather conditions and natural disasters. The Utilities’ results of operations can be affected by the weather and natural disasters. Weather conditions, particularly temperature and humidity, directly impact the demand for electricity. Additionally, severe weather and natural disasters may become more intense and/or frequent because of evolving global climate dynamics. Recent natural disasters such as the Kilauea eruption in 2018, Mauna Loa eruption in 2022, and the Maui windstorm and wildfires in 2023, have disrupted electric utility operations. These types of events can cause outages, property damage and result in significant additional expenses that may not always be recoverable.

Evolving Climate Dynamics Risk—Electric utility operations may be significantly influenced by evolving climate dynamics. While the timing, extent and ultimate effects of evolving climate dynamics cannot be determined with any certainty, such dynamics are predicted to cause sea level rise, which could impact coastal and low-lying areas where much of the Utilities’ electric infrastructure is located. Potential consequences include erosion of beaches, saltwater intrusion into aquifers and surface ecosystems, higher water tables and increased flooding and storm damage due to heavy rainfall. Evolving climate dynamics may also intensify extreme weather conditions including floods, hurricanes, heat waves, and droughts which could increase wildfire risk. These factors along with changes in sea levels, water availability and water quality have the potential to materially and adversely affect the Utilities’ results of operations, financial condition, and liquidity. For example, severe weather and its related impacts could cause significant harm to the Utilities’ physical facilities.

22

Third Party Performance Risk—Electric utility operations depend heavily on third-party suppliers of fuel and purchased power. The Utilities rely on fuel suppliers and shippers, and IPPs to deliver fuel and power, respectively, in accordance with contractual agreements. Approximately 75% of the net energy generated or purchased by the Utilities in 2025 was generated from the burning of fossil fuel oil, and purchases of power by the Utilities provided about 41% of their total net energy generated and purchased for the same period. Failure or delay by fuel suppliers and shippers to provide fuel pursuant to existing contracts, or failure by a major IPP to deliver as anticipated in its PPA, could disrupt the ability of the Utilities to deliver electricity, affect the Utilities’ maintenance schedules that could affect future reliability and require the Utilities to incur additional expenses to meet the needs of their customers that may not be recoverable. In addition, as the 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. Also, as these contractual agreements end, the Utilities may not be able to purchase fuel and power on terms equivalent to the current contractual agreements.

Capacity Risk—The capacity provided by the Utilities’ generating resources and third-party purchased power may not be sufficient to meet customers’ energy requirements. The Utilities rely upon their generating resources and purchased power from third parties to meet their customers’ energy requirements. The Utilities update their generation capacity evaluation each year to determine the Utilities’ ability to meet reasonably expected demands for service and provide reasonable reserves for emergencies and other unplanned events. These evaluations are impacted by a variety of factors, including customer energy demand, energy conservation and efficiency initiatives, economic conditions, and weather patterns. If the capacity provided by the Utilities’ generating resources and third-party purchased power is not adequate relative to customer demand, the Utilities may have to contract to buy more power from third parties, invest in additional generating facilities over the long-term, or extend the operating life of existing utility units. Any failure to meet customer energy requirements could negatively impact the satisfaction of the Utilities’ customers, which could have an adverse impact on the Utilities’ business, reputation and results of operations.

The Energy Reserve Margin, the planning criteria used to determine generation adequacy, is the percentage which the system generation capacity must exceed the system load in each hour. The Utilities’ Energy Reserve Margin is satisfied from 2026 through 2030 with the addition of planned generation and storage resource additions for all islands except for Hawaii Island and Lanai, which forecasts are near or slightly below target levels. The One Big Beautiful Act signed into law by President Trump on July 4, 2025, impacts the ability of recently selected and new wind and solar projects to qualify for federal tax credits. Any loss in renewable energy tax credits will likely result in higher prices for new renewable projects, which rely on such incentives to provide clean, affordable energy. The Utilities have plans to address these issues through managing maintenance schedules of existing generations, and if necessary, may request for voluntary customer conservation during periods of high power demands. The environment for resource planning has increased in complexity and uncertainty and the Utilities will continue using a portfolio approach to meet its obligation to serve. This includes increased renewable energy, energy storage, and other potential options, both supply side and customer programs. If the Utilities are unable to meet customer energy requirements, it could negatively impact the satisfaction of the Utilities’ customers, which could have an adverse impact on the Utilities’ business, reputation and results of operations.

Stakeholder Activism Risk—Electric utility and third-party purchased power projects may be significantly impacted by stakeholder activism. The potential impact of stakeholder activism could increase total utility project costs, and delay the permitting, construction and overall timing 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. If a utility project cannot be completed, the project costs may need to be written off in amounts that could result in significant reductions in Hawaiian Electric’s consolidated net income and negatively impact its financial condition and liquidity.

Operational Risk—Electric utility generating facilities are subject to operational risks that could result in unscheduled plant outages, unanticipated and/or increased operation and maintenance expenses, increased power purchase costs, and decreased reliability. Operation of electric generating facilities involves certain risks which can adversely affect energy output, efficiency levels, and reliability. Included among these risks are facility shutdowns or power interruptions due to insufficient generation or a breakdown or failure of equipment or processes. In addition, operations could be negatively impacted by interruptions in fuel supply, inability to negotiate satisfactory collective bargaining agreements when existing agreements expire or other labor disputes, inability to comply with regulatory or permit requirements, disruptions in delivery of electricity, operator error, adverse weather or environmental conditions and catastrophic events such as earthquakes, tsunamis, hurricanes, fires, explosions, lava flows, floods or other similar occurrences affecting the Utilities’ generating facilities or transmission and distribution systems.

Workforce Retention Risk—The Utilities may be adversely affected by not being able to attract and retain qualified personnel. The Utilities’ workforce, particularly key executives, are critical to their ability to achieve their business strategies. If the Utilities are unable to successfully attract or retain a skilled workforce, the Utilities may face the risk of disruptions, which could have an adverse impact on the Utilities’ business and results of operations. For example, Act 258 sets forth a condition on the securitization that may prohibit the Utilities from providing any increase in compensation, including any

23

bonuses, to their officers for a period of time determined by the PUC. The inability to provide reasonable compensation could negatively impact the Utilities’ ability to attract and retain qualified executives.

Legislative Risk—The Utilities may be adversely affected by new legislation, executive orders or administrative actions. The Utilities operations are subject to regulations under a wide variety of federal and state regulations and policies. Changes to federal and state laws, rules, regulations and policies are continuous and ongoing and the federal administration, the U.S. Congress, state legislatures and state administrations may enact and implement new laws, regulations and policies that could adversely and materially affect us. The new federal administration has indicated its intent to implement material changes to the federal government’s structure and operations and to advocate material changes to federal laws, regulations and policies. The Utilities cannot predict future changes in laws, regulations and policies, how they will be implemented and interpreted, or the ultimate effect that this changing environment will have on us. There can be no assurance that laws, regulations and policies will not be changed in ways that have a material adverse effect on the Utilities’ operations, financial condition, results of operations, and cash flows. The federal and state executive branches, Congress, the Hawaii legislature and governmental agencies have adopted, or are considering adopting, a number of measures that will significantly affect the Utilities, as described below.

Renewable Portfolio Standards law. The 2001 Hawaii Legislature adopted a law requiring the Utilities to meet a renewable portfolio standard, which has been amended over the years. The most recent amendment to Hawaii’s RPS law occurred in July 2022, which former Governor Ige signed as Act 240 (H.B.2089), that amended the RPS calculation from renewable energy as a percentage of sales to renewable energy as a percentage of total generation. The amended RPS calculation results in a lower calculated percentage than the amount calculated under the previous methodology. The change in the definition is to be applied prospectively to future milestone measurements and will require that the Utilities acquire more renewable energy than under the previous RPS calculation to comply with the RPS milestones. The Utilities are committed to achieving these milestones and met the 2015 and 2020 RPS; however, risks such as potential delays in IPPs being able to deliver contracted renewable energy, it is possible the Utilities may not attain the required renewable percentages in the future, and management cannot predict the future consequences of failure to do so (including potential penalties to be assessed by the PUC). On December 19, 2008, the PUC approved a penalty of $20 for every megawatt-hour (MWh) that an electric utility is deficient under Hawaii’s RPS law. The PUC noted, however, that this penalty may be reduced, in the PUC’s discretion, 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, as described in the RPS law and in an RPS framework adopted by the PUC. In addition, the PUC ordered that the Utilities will be prohibited from recovering any RPS penalty costs through rates.

Renewable energy. In 2007, a measure was passed by the Hawaii legislature stating that the PUC may consider the need for increased renewable energy in rendering decisions on utility matters. Due to this measure, it is possible that, if energy from a renewable source is more expensive than energy from fossil fuel, the PUC may still approve the purchase of energy from the renewable source, resulting in higher costs.

Executive orders. In 2025, President Trump has issued multiple executive orders that impact federal funding. The Utilities continue to monitor for any new executive orders and any changes that are passed down through the federal contracting officer for the Resilience Program.

Evolving climate dynamics and greenhouse gas emissions reduction. National and international concern about evolving climate dynamics and the contribution of greenhouse gas (GHG) emissions (including carbon dioxide emissions from the combustion of fossil fuels) to such dynamics have led to federal legislative and regulatory proposals and action by the State of Hawaii to reduce GHG emissions.

Hawaii Revised Statutes (HRS) § 269-6(b) requires that “in making determinations of the reasonableness of the costs pertaining to electric or gas utility system capital improvements and operations, the PUC shall explicitly consider, quantitatively or qualitatively, the effect of the state’s reliance on fossil fuels on price volatility, export of funds for fuel imports, fuel supply reliability risk, and greenhouse gas emissions.” Based on HRS § 269-6(b) and recent case law discussing the scope of this section, the Utilities are performing GHG analyses to quantitatively or qualitatively describe the GHG emissions of proposed projects involving system capital improvements and operations that are submitted to the PUC for approval. On June 20, 2024, House Bill 2390 was signed into law as Act 54 and took effect on July 1, 2024. Act 54 authorizes the PUC to waive a lifecycle GHG analysis for energy projects that do not involve combustion. On September 18, 2024, the PUC approved the Utilities’ waiver requests for the Stage 3 solar plus storage and wind projects.

In June 2018, House Bill 2182 was signed into law as Act 15 and took effect on July 1, 2018. Among its provisions, Act 15 aligned the state’s clean energy and carbon sequestration efforts with climate initiative goals and established a statewide carbon neutral goal by 2045. Under this Act, efforts would be made to “sequester more atmospheric carbon and greenhouse gases than emitted within the state as quickly as practicable, but no later than 2045.” The Hawaii Climate Change Mitigation and Adaptation Commission, administratively placed under the State Department of Land and Natural Resources, was charged with endeavoring to achieve the target, and giving consideration to the impact of its plans, decisions and strategies on the state’s

24

ability to attain the goal. The general functions, duties and powers of the Hawaii Climate Change Mitigation and Adaptation Commission are set forth in HRS § 225P-3. To achieve its mandates, the Hawaii Climate Change Mitigation and Adaptation Commission may recommend plans, decisions and strategies that could have an impact on various entities including the Utilities. In July 2022, House Bill 1800 was signed into law as Act 238 and took effect on July 1, 2022. The Act established a goal for the statewide greenhouse gas emissions limit to be at least 50% below 2005 levels by 2030.

The Utilities have taken, and continue to identify opportunities to take, direct action to reduce GHG emissions from their operations while focusing on reliability and managing cost impacts, including, but not limited to, supporting demand-side management programs that foster energy efficiency, using renewable resources for energy production and purchasing power from IPPs generated by renewable resources, and burning renewable biodiesel at selected Hawaiian Electric and Maui Electric generating units. 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 in Hawaiian Electric’s MD&A. The One Big Beautiful Act signed into law by President Trump 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 and expect to meet or exceed the State of Hawaii’s 2030 RPS goals.

Alternative business models. The Utilities are regulated operations engaged in the production, purchase, transmission, distribution and sale of electricity as a vertically integrated electric company. Any changes through the enactment of law to their current business model to alternative models, such as co-ops or a municipal, or to unbundle generation from transmission and distribution could potentially cause the Utilities to lose their competitive advantages and negatively impact the Utilities’ results of operations.

The foregoing legislation or legislation that now is, or may in the future be, proposed, such as potential carbon “cap and trade” legislation that, if applicable, may fundamentally alter costs to produce electricity and accelerate the move to renewable generation, present risks and uncertainties for the Utilities.

Renewable Transition Risk—The Utilities may be subject to increased operational challenges and their results of operations, financial condition and liquidity may be adversely impacted in meeting the commitments and objectives of clean energy initiatives, Renewable Portfolio Standards (RPS) and other climate-related goals. The far-reaching nature of the Utilities’ renewable energy commitments and the RPS and other climate related goals present risks to the Company. Among such risks are: (1) the potential delay by the Public Utilities Commission of the State of Hawaii (PUC) in considering (and potential disapproval of actual or proposed) renewable energy proposals and related costs; (2) the dependence on outside parties, such as the state, developers and third-party suppliers of renewable energy, which if the Utilities are unsuccessful in negotiating purchased power agreements with such IPPs or if a major IPP delays or fails to deliver the anticipated capacity and/or energy in its purchased power agreement, could impact the Utilities’ achievement of their commitments to RPS and other climate-related goals, eligibility for performance incentive mechanisms associated with the speed of increasing renewable generation, the ability to retire fossil fuel units, and/or the Utilities’ ability to deliver reliable service; (3) delays in acquiring or unavailability of non-fossil fuel supplies for renewable generation; (4) the impact of intermittent power to the electrical grid and reliability of service if appropriate supporting infrastructure is not installed or does not operate effectively; (5) the inability to recover the undepreciated cost of fossil fuel generating units if they are required to be retired before the end of their expected useful life; (6) uncertainties surrounding current and future renewable technologies, such as solar power, wind power, biofuels, battery storage, hydro, hydrogen, as well as related environmental assessments required to meet RPS and other climate-related goals; (7) uncertainty with regard to federal policy, including tax credit availability for both IPPs and Utility projects; (8) the impacts of implementation of the renewable energy proposals on future costs of electricity and potential penalties imposed by the PUC for delays in the commercial operations of renewable energy projects; (9) the likelihood that the Utilities may need to make substantial investments in related infrastructure, which could result in increased borrowings and, therefore, materially impact the financial condition and liquidity of the Utilities; (10) the imputed debt related to the executed renewable power purchase agreements could result in a credit rating downgrade for the Utilities and the Company; and (11) the commitment to support a variety of initiatives, which, if approved by the PUC, may have a material impact on the results of operations and financial condition of the Utilities depending on their design and implementation. These initiatives include, but are not limited

25

to, programs to enable more customer-sited generation. The implementation of these or other programs may adversely impact the results of operations, financial condition and liquidity of the Utilities.

ITEM 1B. UNRESOLVED STAFF COMMENTS

HEI: None.

Hawaiian Electric: Not applicable.

ITEM 1C. CYBERSECURITY

Cybersecurity risk oversight and management is a critical component of the Company’s overall enterprise risk management and top priority for the Company and its Board of Directors. The Company’s Board of Directors has delegated oversight of Enterprise Risk Management, which includes cybersecurity, to the HEI and Hawaiian Electric Audit and Risk Committees (collectively, the ARCs). The ARCs exercise their oversight responsibility of cybersecurity through quarterly (or more frequently if necessary) cybersecurity risk updates and reports of incidents, if any, by management (primarily the Utilities’ Chief Information Officer and Chief Information Security Officer (CISO)). In early 2023, in recognition of the heightened cybersecurity risks facing the Company, the ARCs formed the non-fiduciary Cybersecurity Working Group (CWG) to assist the ARCs with their oversight of such risks, including through: conducting periodic meetings with management to discuss cyber risk, risk treatment, and operational activities relative to cyber risk treatment; evaluating cybersecurity areas highlighted by the ARCs, including areas the CWG deems higher risk or topical; reporting to the ARCs on a quarterly basis, or more frequently as needed; and coordinating with the Company’s management on regular trainings and tabletop exercises for the Board of Directors. In early 2026, the ARCs broadened the oversight of the CWG to include physical security risk, given the potential interconnectedness of cybersecurity and physical security risks. The updated working group, now named the Cyber and Physical Security Working Group (CPWG), continues to perform the cybersecurity-related oversight described above with respect to the CWG in addition to added oversight relating to physical security risk.

Electric utility

System overview. The Utilities rely on evolving and increasingly complex operational systems and infrastructure and information systems, networks and other technologies, which are interconnected with the systems and network infrastructure owned by third parties, to support a variety of business processes and activities, including procurement and supply chain, invoicing and collection of payments, customer relationship management, human resource management, the acquisition, generation and delivery of electrical service to customers, and to process financial information and results of operations for internal and external reporting and compliance with regulatory, financial reporting, legal and tax requirements. The Utilities use their systems and infrastructure to create, collect, store, and process sensitive information, including personal information regarding customers, employees and their dependents, retirees, and other individuals.

Risk management and strategy. The Utilities have a cybersecurity program in place, which is integrated into the overall risk management program and includes a risk management strategy and risk assessment policy, which are disseminated and maintained by the CISO, revisited annually and govern the enterprise cybersecurity risk and maturity assessment process. The program is aligned with the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF), and leverages a risk-based approach to optimize security investment and advance the security program’s maturity and security posture over time.

The Utilities’ cybersecurity program adopts security measures designed to protect the confidentiality, integrity, and availability of information technology systems, network infrastructure and other assets. The Utilities’ security measures, such as awareness and training, monitoring, etc. are designed to prevent, detect, and minimize the effects of a cybersecurity incident. These measures are periodically evaluated and audited against the NIST CSF by internal audit and independent third-party cybersecurity specialists.

The CISO actively monitors developments in the area of cybersecurity and is involved in various related government and industry groups and briefs the Company’s Board quarterly or as needed, including through the CPWG, on relevant cybersecurity issues. The Utilities continue to make investments in their cybersecurity program, including personnel, technologies, cyber insurance and training of Utilities personnel.

The Utilities have disaster recovery and incident response plans in place to protect their businesses from information technology service interruptions. The disaster recovery plans are established to help prevent the loss of customer data, service interruptions and disruptions to operations or damage to important facilities. In addition, the Utilities also maintain cyber liability insurance that covers certain damages caused by cyber incidents.

Despite the Utilities’ security measures, all of their systems are vulnerable to disability, failures or unauthorized access caused by natural disasters, physical attacks, cybersecurity incidents, security breaches, user error, unintentional defects created by system changes, military or terrorist actions, power or communication failures or similar events.

26

To date, the Utilities are not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Utilities, including their business strategy, results of operations or financial condition. For further information, see “The Company’s information technology and operations could be impacted by a cyber incident, cybersecurity breach, or physical attack that could materially and adversely affect its businesses and reputation” in Item 1A. Risk Factors.

Governance. Cybersecurity governance is a critically important part of managing security and risk, and helps ensure that the Utilities’ cybersecurity program aligns with its business objectives, complies with government and industry regulations, and achieves the goals that leadership has set out for managing security and risk.

The Company’s Board of Directors oversees risks from cybersecurity threats. Oversight includes quarterly or as needed reporting from the CISO on the overall cybersecurity risk reduction program maturity, emerging and current cybersecurity risks, and the cybersecurity threat landscape.

The CISO has over 30 years of experience in assessing and managing cyber risks, is responsible for day-to-day management of cybersecurity risks and regularly reports to the Board of Directors through the CPWG.

All Other segment

HEI does not have an information technology (IT) or cybersecurity risk management (CRM) department, including the resources or expertise, to manage IT/CRM-related matters and processes. HEI relies on Hawaiian Electric to provide most of its IT/CRM-related services pursuant to a Service Level Agreement (SLA), amended, as of November 30, 2023, between HEI and Hawaiian Electric. HEI also employs third party cybersecurity consultants as needed to assist in managing CRM-related matters. The SLA outlines specific services that Hawaiian Electric provides to HEI, which includes support on all IT/CRM-related matters, IT service desk support, electronic file storage and backup, hardware and software installation, inventory and maintenance, standard networking and telecommunication support, and other various IT/CRM matters, including periodic reporting to HEI’s Board of Directors and CPWG. Refer to Hawaiian Electric’s cybersecurity discussion for more information.

The SLA services provided by Hawaiian Electric are mainly for applications and systems on Hawaiian Electric’s infrastructure, networks and servers. The SLA does not cover support for certain software applications that were procured outside of Hawaiian Electric’s procurement and IT policies and procedures. These include HEI’s general ledger application itself, excluding the infrastructure that the general ledger application is installed on, and certain cloud-based software. Although these applications are not supported by Hawaiian Electric, security measures and internal control procedures related to user access and periodic security reviews have been implemented on these applications and are performed on an on-going basis in accordance with Hawaiian Electric’s IT policies and procedures. These controls are required to protect HEI’s financial and other sensitive information, as well as to prevent cybersecurity breaches on Hawaiian Electric’s infrastructure, networks and servers. In the event of a cybersecurity breach on these applications not supported by Hawaiian Electric, HEI employs third party cybersecurity consultants to assess and resolve issues resulting from a breach, depending on its severity. Hawaiian Electric may also provide guidance and support to assist HEI in assessing and resolving cybersecurity breaches. HEI has also formulated disaster recovery plans, which are updated on an annual basis, involving all of its critical applications.

HEI’s cybersecurity governance is primarily integrated within Hawaiian Electric’s cybersecurity governance plan and processes. HEI’s Board of Directors and CPWG are tasked with overseeing risks from cybersecurity threats through routine quarterly, or as needed, updates and periodic deep-dive sessions. These updates cover cybersecurity incidents, as well as overall cybersecurity risk reduction program maturity, emerging and current cybersecurity risks, and the cybersecurity threat landscape.

The HEI CFO oversees all IT and cybersecurity matters at HEI, including having oversight responsibility for the services delivered under the SLA. Since the HEI CFO does not have expertise in cybersecurity, the HEI CFO works with the Hawaiian Electric CISO and, if necessary, with third-party cybersecurity consultants on assessing, identifying, and managing material cybersecurity matters impacting HEI. There were no cybersecurity incidents that have materially affected or that we believe are reasonably likely to materially affect HEI, including its business strategy, results of operations or financial condition.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

HEI:

Certain of the information required by this item is disclosed in Note 15 of the Consolidated Financial Statements and “Equity compensation plan information” under “Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters” of this Form 10-K.

HEI’s common stock is traded on the New York Stock Exchange under the ticker symbol “HE.” As of February 17, 2026, HEI had 2,663 registered shareholders (i.e., holders of record of HEI common stock), 17,477 DRIP participants and total record shareholders of 20,140. The HEI Board of Directors evaluates the dividend quarterly and considers many factors in the evaluation including, but not limited to, the Company’s results of operations, the long-term prospects for the Company, and the current and expected future economic conditions. In August 2023, due to 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 of 2023 dividend.

Purchases of HEI common shares were made on the open market during the fourth quarter to satisfy the requirements of certain plans as follows:

ISSUER PURCHASES OF EQUITY SECURITIES

NA Not applicable.

* Trades (total number of shares purchased) are reflected in the month in which the order is placed.

** The purchases were made to satisfy the requirements of the HEI Dividend Reinvestment and Stock Purchase Plan (DRIP) and the Hawaiian Electric Industries Retirement Savings Plan (HEIRSP), for shares purchased for cash or by the reinvestment of dividends by participants under those plans and none of the purchases were made under publicly announced repurchase plans or programs. Average prices per share are calculated exclusive of any commissions payable to the brokers making the purchases for the DRIP and the HEIRSP. Of the “Total number of shares purchased,” 6,547 of the 16,006 shares, 4,952 of the 13,920 shares and 10,107 of the 22,278 shares were purchased for the DRIP; the remaining shares were purchased for the HEIRS. The repurchased shares were issued for the accounts of the participants under registration statements registering the shares issued under these plans.

Hawaiian Electric:

Since a corporate restructuring on July 1, 1983, all the common stock of Hawaiian Electric has been held solely by its parent, HEI. Although Hawaiian Electric’s common stock is registered under Section 12(g) of the Exchange Act, all such outstanding common stock is owned by HEI and there is no established public trading market for Hawaiian Electric’s common stock. Accordingly, information required with respect to “Market information” and “holders” is not applicable to Hawaiian Electric.

The dividends declared and paid to HEI on Hawaiian Electric’s common stock for the quarters of 2025 and 2024 were as follows:

HEI and Hawaiian Electric (in the case of Hawaiian Electric, only the information related to Hawaiian Electric and its subsidiaries):

The following discussion should be read in conjunction with the Consolidated Financial Statements and the related Notes that appear in Item 8 of this report. For information on factors that may cause HEI’s and Hawaiian Electric’s actual future results to differ from those currently contemplated by the relevant forward-looking statements, see “Cautionary Note Regarding Forward-Looking Statements” at the front of this report and “Risk Factors” in Item 1A. The general discussion of HEI’s consolidated results should be read in conjunction with the Electric utility discussion that follows.

HEI Consolidated

Executive overview and strategy. HEI is a holding company with operations primarily focused on Hawaii’s electric utility sector after selling its bank operations on December 31, 2024. In 2017, HEI formed Pacific Current to make investments in non-regulated renewable energy and sustainable infrastructure projects. On December 30, 2024, HEI, ASB, and ASB Hawaii, a wholly owned subsidiary of HEI and ASB’s parent holding company, entered into investment agreements to sell 90.1% of the common stock of ASB to various investors, including certain ASB officers and directors of ASB. The sale transaction closed on December 31, 2024 and no investor acquired more than 9.9% of the common stock of ASB. The proceeds from the sale were used to repay a ratable portion of each of HEI’s senior notes in April 2025. Subsequent to the sale, HEI has one reportable segment: Electric utility. HEI and its other subsidiaries which are not reportable segments are grouped and reported as an “All Other” non-reportable segment.

Electric utility. Hawaiian Electric, Hawaii Electric Light and Maui Electric (Utilities) are regulated operating electric public utilities engaged in the production, purchase, transmission, distribution and sale of electricity on the islands of Oahu; Hawaii; and Maui, Lanai and Molokai, respectively.

All Other. The All Other segment primarily comprises the results of Pacific Current, which invested in non-regulated clean energy and sustainable infrastructure in the State of Hawaii to help reach the state’s sustainability goals, and HEI’s corporate-level operating, general and administrative expenses. Subsequent to the Maui windstorm and wildfires, HEI and Pacific Current have suspended new investments and undertook a comprehensive review of strategic options for the assets of Pacific Current. As part of HEI’s comprehensive review of strategic options for Pacific Current, all investments of Pacific Current that were made through its subsidiaries were sold in 2025, except for Mahipapa, its remaining operating subsidiary which is in the process of being sold. The All Other segment also includes ASB Hawaii, which previously owned ASB, and a 40% interest in GLST1, an entity created for the specific purpose of holding HEI’s and Hawaiian Electric’s first liability installment payment pursuant to the settlement agreements to settle the tort-related claims in the litigation arising out of the Maui windstorm and wildfires.

A major focus of HEI’s financial strategy is to grow core earnings/profitability at the Utilities in a controlled risk manner and optimize operating, capital and tax efficiencies in order to support its dividend and deliver shareholder value. HEI also continues to work on strategic financing plans to raise capital necessary to fund the settlement of wildfire tort claims.

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

On September 5, 2025, HEI and Hawaiian Electric each amended their senior unsecured revolving credit facility (the HEI Revolving Facility and the Hawaiian Electric Revolving Facility, respectively) resulting in increased borrowing capacities and available liquidity. HEI increased its revolving commitments available under the HEI Revolving Facility to $300 million from $175 million and extended the termination date to September 5, 2030 from May 14, 2027. Hawaiian Electric increased its revolving commitments available under the Hawaiian Electric Revolving Facility to $300 million from $200 million and extended the termination date 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 Revolving Facility also allows for commitment increases of up to an additional $75 million, subject to customary conditions. Refer to Note 6 of the Consolidated Financial Statements for additional terms of the amended credit facilities.

In addition, on September 18, 2025, Hawaiian Electric issued $500 million in unsecured senior notes with an interest rate of 6.00% and maturing on October 1, 2033 (refer to Note 7 of the Consolidated Financial Statements for additional terms of the unsecured senior notes). 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.

In June 2025, the Utilities submitted a request with the PUC to terminate or suspend the 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. In September 2025, the PUC dismissed the request without prejudice. In its order, the PUC provided guidance on the topics to be addressed in any future request. On October 31, 2025 HEI and Hawaiian Electric filed a revised request with the PUC to terminate or suspend the ATRs. After responding to information requests from the Consumer Advocate, the Consumer Advocate issued its statement of position on February 4, 2026. The Consumer Advocate supported the approval of the request with the condition that before any recovery of expenses related to HEI, the Utilities should give the Consumer Advocate and the PUC advance notice of likely changes to recovery. HEI and Hawaiian Electric informed the PUC that the docket was ready for decision making on February 5, 2026.

Following a hearing on December 17, 2025, at which the court orally granted final approval of the Class Settlement Agreement and no class member objected, the Maui Circuit Court entered a written order granting such final approval on January 26, 2026. The deadline to file appeals from that order was February 25, 2026, and as of February 26, 2026, no appeal appeared on the docket. As it appears no party appealed the final approval of the Class Settlement Agreement, it appears that such final approval order is now final and unappealable.

The tort Settlement Agreements do not resolve claims with insurers who have asserted or could assert subrogation claims in separate lawsuits, and such insurers are not parties to the Settlement Agreements, but resolving such claims in the manner set forth in the Settlement Agreements (summarized below) is a condition that must be satisfied before any payment is due from the defendants. On December 30, 2025, the court entered judgment in favor of the defendants in the two principal direct subrogation actions brought by various insurers as to all direct subrogation claims except for 16 such claims associated with insureds who had opted out of the class settlement and had not yet settled. On January 21, 2026, certain plaintiff insurers appealed the grant of summary judgment in these two actions. No briefing schedules in these appeals have been set. 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 conditioned on, among other things, approval by the boards of the Company and Hawaiian Electric; the finalization and court approval of the Securities Actions stipulation of settlement; the finalization by February 26, 2026 and subsequent court approval of the stipulation of settlement in the Derivative Actions (defined and discussed below); and entry of a judgment of dismissal following final court approval. 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 February 26, 2026, the United States District Court for the Northern District of California held a hearing to determine whether to preliminarily approve the Securities Action Stipulation of Settlement. Following the hearing, the court indicated that it will issue an order and set a hearing date for the final approval of the settlement.

In connection with the execution of the Securities Action Term Sheet, HEI accrued, as of December 31, 2025, $47.8 million, and concurrently 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 addition, 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 conditioned on, among other things, the approval by the boards of HEI and Hawaiian Electric (including their independent directors) of the Derivative Litigation Settlement Agreement; final court approval of the Derivative Litigation Settlement Agreement; and entry of final judgment and orders of dismissal in 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. On March 9, 2026, the United States District Court for the District of Hawaii is scheduled to hold a hearing to determine whether to preliminarily approve 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

31

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.

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 (the Insurers). The Insurers are commercial property insurers that insured the Hawaiian Electric Plaintiffs at the time of the August 2023 Maui windstorm and wildfires. The Insurers have acknowledged coverage under the policies at issue for loss or damage to the Hawaiian Electric Defendants’ property and have paid a portion of the companies’ 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 Insurers’ obligations under the policies, as well as a determination that the Insurers have breached the policies.

Sustainability. At HEI, sustainability principles have long been embedded as applicable within the Company’s activities and are integral to the Company’s efforts to create value for all of its stakeholders. With all of its operations isolated in the middle of the Pacific Ocean, the Company’s long-term health and financial performance are inextricably linked with the strength of the Hawaii economy, its communities, and the environment. That is why long-term shareholder and broader stakeholder value are both served by the Company’s efforts to serve as a catalyst for a better Hawaii.

In 2021, the Company identified a number of priorities that reflect the essential connection between the health of Hawaii’s environment, economy and communities and HEI’s long-term success. Those sustainability priorities included:

•decarbonizing the Company’s operations and the broader Hawaii economy;

•promoting Hawaii’s economic health and improving affordability for all residents;

•ensuring resilience, including safety, as the Company adapts to evolving climate dynamics, which are exacerbating conditions that can lead to increasing risk of droughts, severe storms, flooding, wildfires and other extreme weather events and natural disasters;

•maintaining resilience as the Company navigates the clean energy transition;

•advancing digitalization of the Company’s operations to better serve customers and increase efficiency while protecting against cyber-security challenges;

•promoting inclusion both within the Company and in the ways the Company interacts with and impacts external stakeholders;

•increasing employee engagement; and

•identifying and integrating climate-related risks and opportunities throughout the Company’s planning and decision-making.

The Company has integrated sustainability considerations as appropriate into governance structures, strategies and risk management. This includes:

•full HEI Board review of sustainability-related strategies, Audit & Risk Committee oversight of sustainability-related risks, Compensation & Human Capital Management Committee responsibility for sustainability-related compensation matters and human capital management and Nominating and Corporate Governance Committee responsibility for ensuring an appropriate board governance framework is in place with respect to sustainability.

•robust sustainability and risk management expertise among board members, including directors with direct experience in renewable energy, policy and strategy in the context of evolving climate dynamics, and risk and environmental management.

•sustainability goals incorporated as part of HEI and Utility executive incentive compensation as appropriate.

•sustainability considerations explicitly woven into strategic planning efforts and enterprise risk management processes.

The Company is committed to transparency and providing information to allow customers, community leaders, investors and other stakeholders to understand how the Company’s strategies and operations advance sustainability and long-term stakeholder value creation.

The Company issued its first consolidated sustainability report in September 2020. The report was aligned with Sustainability Accounting Standards Board guidance. The Company has since further developed its sustainability reporting to include disclosures regarding risks and opportunities related to evolving climate dynamics, as well as associated risk management and governance processes, based on recommendations from the Task Force on Climate-related Financial Disclosures. It has also outlined key impacts for the Company under two climate scenarios, including a scenario targeted to limit global temperature rise to two degrees Celsius or lower. The Company’s most recent reports include HEI’s enterprise-

32

wide GHG emissions inventory. Net enterprise-wide GHG emissions in measured categories have decreased over time, driven largely by reductions in the utility’s generation-related emissions intensity. The Company’s sustainability reports can be found at www.hei.com/sustainability.

Note: Totals may not foot due to rounding.

In 2025, income (loss) from continuing operations for HEI common stock increased to $123 million compared to $(1,323) million in 2024, due to $1,395 million lower net income in 2024 at the Utilities as a result of recording $1,875 million of provision, net, for wildfire tort-related claims in 2024. In 2024, income (loss) from continuing operations for HEI common stock decreased to $(1,323) million compared to $146 million in 2023, due to $(1,420) million lower net income at the Utilities as a result of recording $1,875 million of provision, net, for wildfire tort-related claims in 2024. See “Electric utility” and “HEI Consolidated—All Other segment” sections below for additional information on year-to-year fluctuations.

The Company’s effective tax rate (combined federal and state income tax rates) was 24% (tax expense) in 2025, compared to 26% (tax benefit) in 2024. The Company’s effective tax rate was lower than 2024 primarily due to the substantial pre-tax loss in 2024 resulting from the Utilities’ accrual of the loss contingencies related to the wildfire tort-related claims and because the impact of permanent items had a smaller impact on the effective tax rate in 2024, partially offset by recapture of investment tax credits and lower research and development tax credit claims in 2025.

Also includes $3.5 million accrual related to the Utilities’ share of settlement administration fees for 2024. See Note 2 of the Consolidated Financial Statements.

5 Excludes expenses related to discontinued operations amounting to $1.3 million and $11.3 million for 2024 and 2023, respectively.

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

From August 8, 2023 through December 31, 2025, HEI and its subsidiaries have incurred approximately $2.3 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 December 31, 2025, HEI and its subsidiaries have approximately $10 million, nil and $71 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 year-end.

With the Company accruing its losses related to a settlement of all wildfire tort-related legal claims and cross claims as of December 31, 2025, the Company expects the Electric utility and HEI to use the remaining $10 million of insurance coverage under its excess liability policy primarily for legal expenditures, in excess of amounts deferred, in connection with the Maui windstorm and wildfires.

Economic conditions.

Note: The statistical data in this section is from public third-party sources that management believes to be reliable (e.g., Department of Business, Economic Development and Tourism (DBEDT), University of Hawaii Economic Research Organization (UHERO), U.S. Bureau of Labor Statistics, Department of Labor and Industrial Relations (DLIR), Hawaii Tourism Authority (HTA), Honolulu Board of REALTORS® and national and local news media).

In the fourth quarter of 2025, the average daily passenger count was 2.0% 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 fourth quarter, international visitor arrivals (excluding Japan) remained 18.0% below 2019 levels. Due to the weak yen, Japanese visitors are 36.6% below 2019 levels.

Hawaii’s seasonally adjusted unemployment rate in December 2025 was 2.2%, lower than the December 2024 rate of 3.0%. The national unemployment rate in December 2025 was 4.4%, slightly higher than the December 2024 rate of 4.1%. According to a recent forecast by UHERO, issued on December 12, 2025, jobs in the State will increase by 0.5% in 2025 before decreasing by 0.3% in 2026.

Hawaii real estate activity through December 2025, as indicated by Oahu’s home resale market, resulted in a 1.5% decrease in the median sales price for condominiums and an increase of 3.5% for single-family homes compared to the same period in 2024. The median single-family home price was $1,100,000 in December 2025, slightly lower than the all-time high of $1,185,000, set earlier this year in February 2025. The number of closed sales through December 2025 saw a 1.1% decrease for condominiums and a 3.5% increase for single-family residential homes compared to the same period in 2024.

Hawaii’s petroleum product prices relate to the crude oil in international markets. The price of crude oil has decreased 14.7% over the same quarter in the prior year.

At its December 10, 2025 meeting, the Federal Open Market Committee (FOMC) decided to lower the federal funds rate target range to 3.5% to 3.75%. The FOMC noted that economic growth has moderated, with job gains slowing and unemployment edging up. They further noted that uncertainty around the economic outlook remains elevated, and that they remain attentive to risks on both sides of its dual mandate of achieving maximum employment and 2 percent inflation over the longer run.

UHERO forecasts full year 2026 real GDP and real personal income to be flat, a decrease in total visitor arrivals of 1.3%, and an unemployment rate of 3.0% for the State. According to UHERO, Hawaii’s economy is edging into a mild recession, with tourism in a downturn, likely to result in job losses in 2026.Inflation is also expected to increase as the impacts of tariffs

35

are reflected in consumer prices. Construction continues to be the only major source of economic strength in Hawaii, supported by large federal contracts and ongoing housing and infrastructure needs.

See also “Recent Developments” in the “Electric utility” section below for further discussion of the economic impact of recent events.

All Other segment. The “All Other” business segment (loss)/income 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.

Note: Totals may not foot due to rounding.

In late February 2024, Hamakua Energy’s combustion turbine (CT) and its leased combustion turbine (leased CT) unexpectedly sustained damages resulting in a plant shut down on Hawaii Island. As a result, in April 2024, Hamakua Energy purchased a new CT which was placed into service in June 2024. The leased CT was returned to the lessor and a new leased CT had been delivered and placed into service in September 2024 bringing Hamakua Energy back to full capacity. After conducting an investigation into the root cause of the damages, it was determined that contaminated fuel led to the turbine damages. Pacific Current 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, on February 7, 2025, Pacific Current entered into a Securities Purchase Agreement to sell all the membership interests in Hamakua Holdings, a then wholly owned subsidiary of Pacific Current and parent company of Hamakua Energy, to an unaffiliated third party. The sale transaction closed on March 10, 2025. As a result of the sale transaction, the Company recorded a pre-tax loss on the sale amounting to $13.2 million as of March 31, 2025. The sale of Hamakua Holdings and its subsidiary, Hamakua Energy, does not preclude Pacific Current from seeking recovery of its losses related to the aforementioned damages to its plant facilities from the fuel supplier.

In March 2024, a fire destroyed the cooling tower at the Mahipapa facility on Kauai. The fire was ignited from a vendor’s welding activities being performed on the cooling tower during its scheduled maintenance. As a result, the plant was shut down while repairs were being performed. Mahipapa completed repairs to its facility and commenced operations in early December 2024 and returned to full capacity in the first quarter of 2025. In the first quarter of 2025, Mahipapa received insurance proceeds of $1.4 million under its business interruption policy. In addition to working with its insurance company, Mahipapa is

36

currently working with its legal counsel on seeking reimbursement of its losses related to damages sustained to its plant facilities.

In September 2024, Pacific Current recorded a pretax long-lived asset impairment charge of $35.2 million after determining it was more-likely-than-not that the long-lived assets of Pacific Current will be sold significantly before the end of their previously estimated useful life and that the fair value of certain long-lived assets of Pacific Current were less than its carrying value. In addition, HEI forgave its intercompany loan receivable from Mahipapa, including accrued interest, amounting to $9.6 million. Concurrently, Mahipapa classified its intercompany loan payable to HEI, including accrued interest, of an equivalent amount as an equity contribution. These transactions were accounted for as equity transactions and offset in the Company’s Consolidated Balance Sheets. The impairment charge and intercompany loan transactions were non-cash in nature and did not affect the Company’s current liquidity, cash flows or any debt covenants under the Company’s existing credit agreements.

As part of HEI’s comprehensive review of strategic options for certain assets of Pacific Current, on August 1, 2025, Pacific Current, through an indirect subsidiary, sold all of the membership interests in Mauo, LLC, Alenuihaha Developments, LLC, Kaʻieʻie Waho Company, LLC and Upena, LLC. See Note 3 of the Consolidated Financial Statements for more information.

Liquidity and capital resources. 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 wildfire related litigation noted above).

The Company’s objective continues to be to operate a strong, financially healthy enterprise to empower a thriving future for Hawaii. While the fundamentals of its businesses remain strong, the Company took prudent and measured actions to reinforce its commitment to serving the community for the long term. Subsequent to the Maui windstorm and wildfires, in August 2023, HEI and Hawaiian Electric fully drew down $175 million and $200 million, respectively, on their previously existing revolving credit facilities. 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 6 of the Consolidated Financial Statements for additional information). As of December 31, 2025, HEI and Hawaiian Electric had $20 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 6 of the 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. In addition, HEI paid down a ratable portion of each of HEI’s senior notes in April 2025 amounting to $384 million, using the proceeds from the December 2024 sale of ASB. 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 December 31, 2025, 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 December 31, 2025, 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 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’ 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 Consolidated Financial Statements). The cash for the first installment payment is classified as restricted cash on the Consolidated Balance Sheet as of December 31, 2025.

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 6 of the Consolidated Financial Statements for a description of the HEI and Hawaiian Electric Intercompany Borrowing and Investment Policy.

2 As of December 31, 2025, the Utilities had no commercial paper outstanding. Hawaii Electric Light and Maui Electric had no short-term borrowings from Hawaiian Electric but had long-term intercompany loans from Hawaiian Electric in the amount of $25 million and $90 million, respectively, as of December 31, 2025.

Management believes with the Company’s cash and cash equivalents amount of $502 million and GLST1’s restricted cash amount of $479 million, both as of December 31, 2025, 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, including available sufficient liquidity to fund the first installment of the settlement of wildfire tort claims (expected to be made no sooner than early 2026) and its other cash obligations for the next 12 months following the issuance of its financial statements.

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 result of the August 2023 downgrades of their credit ratings to below investment grade which limits the Company from accessing unsecured, short-term borrowings and continues to restrict access to the capital markets 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 of 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.

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, legal and consulting costs related to the Maui windstorm and wildfires, 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.

Forecasted HEI consolidated “net cash used in investing activities” consists primarily of the net capital expenditures of the Utilities principally related to maintaining and modernizing the grid to allow for the integration of more renewable energy,

38

improved customer reliability, greater system efficiency and enhanced resilience. The Utilities’ capital expenditures are forecasted to be funded primarily through a combination of retained earnings and proceeds from other sources of debt financings (see also discussion regarding other material cash requirements under “Financial Condition–Liquidity and capital resources,” contained in the “Electric utility” section below). In the future, if the Company is unable to refinance scheduled maturing debt, then debt maturities are expected to be repaid with the proceeds from existing cash on hand, other medium- or long-term debt, and/or dividends from subsidiaries. The ability of Hawaiian Electric to pay dividends or make other distributions to HEI are subject to contractual and regulatory restrictions (see Note 15 of the Consolidated Financial Statements). Additional debt and/or equity financing, if available, may be utilized to invest in the Utilities; to pay down commercial paper or other short-term borrowings, if any; to pay interest costs; or to fund unanticipated expenditures, such as increases in the costs of, or an acceleration of, the construction of capital projects of the Utilities or unanticipated utility capital expenditures. In addition, existing debt may be refinanced prior to maturity with additional debt or equity financing (or both).

Certain Maui windstorm and wildfires legal-related costs of HEI and the Utilities are recoverable under $165 million of excess liability insurance, $25 million of professional liability insurance, and $145 million of directors and officers liability insurance policies (see further information in Note 2 of the Consolidated Financial Statements). As of December 31, 2025, HEI and the Utilities have approximately $10 million, nil and $71 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 year-end.

Selected short-term and long-term contractual obligations and commitments. Information about payments under the specified contractual obligations and commitments of HEI and its subsidiaries was as follows:

1Amounts do not include $54 million related to Mahipapa debt which are included in liabilities held for sale as of December 31, 2025. See Note 3 of the Consolidated Financial Statements.

2Amounts do not include $4 million of interest on Mahipapa debt which is included in liabilities held for sale as of December 31, 2025. See Note 3 of the Consolidated Financial Statements.

3As of December 31, 2025, HEI and Hawaiian Electric recorded $48 million and $40 million, respectively, of insurance reimbursement receivable related to the securities class action settlement and tort settlement, respectively. See Note 2 of the Consolidated Financial Statements.

4Amounts do not include $6 million related to Mahipapa leases which are included in liabilities held for sale as of December 31, 2025. See Note 3 of the Consolidated Financial Statements.

5Includes contractual obligations and commitments for capital expenditures and expense amounts.

The table above does not include other categories of obligations and commitments, such as deferred taxes, certain trade payables, amounts that will become payable in future periods under collective bargaining and other employment agreements and employee benefit plans and potential refunds of amounts collected from ratepayers (e.g., under the earnings sharing mechanism). As of December 31, 2025, the fair value of the assets held in trusts to satisfy the obligations of the Company’s retirement benefit plans exceeded the retirement benefit plans’ benefit obligation. Minimum funding requirements for retirement benefit plans have not been included in the table above. See Note 11 of the Consolidated Financial Statements for 2026 estimated retirement benefit plan obligations and contributions.

See “Developments in renewable energy efforts—Biofuel sources” in Hawaiian Electric’s MD&A for additional information on fuel oil purchase obligations. See Notes 4 and 9 of the Consolidated Financial Statements for a discussion of power purchase commitments and operating leases obligations, respectively.

Operating activities provided net cash of $391 million in 2025, $487 million in 2024 and $551 million in 2023, of which operating activities from continuing operations provided net cash of $391 million in 2025, $428 million in 2024 and $443 million in 2023. Investing activities used net cash of $322 million in 2025 and $257 million in 2023 and provided net cash of $258 million in 2024, of which investing activities from continuing operations used net cash of $322 million in 2025, $334 million in 2024 and $436 million in 2023. In 2025, 2024 and 2023, net cash used in investing activities from continuing activities was primarily due to capital expenditures.

Financing activities used net cash of $331 million in 2025 and provided net cash of $155 million in 2024 and $196 million in 2023, of which financing activities from continuing operations used net cash of $331 million in 2025 and provided net cash of $498 million in 2024 and $203 million in 2023. In 2025, net cash used in financing activities included repayment of long-term debt, revolving credit facilities and short-term debt and redemption of preferred stock, partly offset by issuance of long-term debt. In 2024, net cash provided by financing activities from continuing operations included issuance of common stock (common stock offering) and increase in short-term debt, partly offset by repayment of long-term debt and revolving credit facilities. In 2023, net cash provided by financing activities from continuing operations included proceeds from revolving credit facilities, long-term debt and short-term debt, partly offset by repayment of long-term and short-term debt, net decreases in short-term borrowings and payment of common and preferred stock dividends.

Other than capital contributions from their parent company, intercompany services (and related intercompany payables and receivables), Hawaiian Electric’s periodic short-term borrowings from HEI (and related interest), if any, and the payment of dividends to HEI, the electric utility is largely autonomous in its operating, investing and financing activities. (See the electric utility segment’s discussion of its cash flows in its “Liquidity and capital resources” section below.) During 2025, Hawaiian Electric paid cash dividends to HEI of $30 million.

In August 2023, due to 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 cash to 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 quarterly dividend for each of the first, second and third quarters of 2025. 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.

A portion of the net assets of Hawaiian Electric is not available for transfer to HEI in the form of dividends, loans or advances without regulatory approval. In the absence of an unexpected material adverse change in the financial condition of the Utilities, such restrictions are not expected to significantly affect the operations of HEI or its ability to meet its debt or other cash obligations. See Note 15 of the Consolidated Financial Statements.

The consolidated capital structure of HEI was as follows:

(dollars in millions)

Short-term borrowings, net $ — — % $ 49 1 %

Preferred stock of subsidiaries — — 34 1

Prior to the Maui windstorm and wildfires, HEI utilized short-term debt, typically commercial paper, to support normal operations, to refinance commercial paper, to retire long-term debt, to pay dividends and for other temporary requirements, including short-term financing needs of its subsidiaries. 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 December 31, 2025. Historically, HEI also periodically utilized unsecured long-term debt, to fund investments in and loans to its subsidiaries to support their capital improvement or other requirements, to repay long-term and short-term indebtedness and for other corporate purposes. The downgrades of HEI’s and Hawaiian Electric’s credit ratings have negatively impacted each of HEI’s and Hawaiian Electric’s ability to access lower cost sources of capital.

See Notes 6 and 7 of the Consolidated Financial Statements for a brief description of the Company’s loans.

Credit ratings. On May 28, 2025, June 4, 2025 and June 27, 2025, Moody’s, Fitch and S&P, respectively, upgraded HEI’s credit ratings. As of February 17, 2026, the Fitch, Moody’s and S&P ratings of HEI were as follows:

Fitch Moody’s S&P

From1 To From1 To From1 To

Outlook Stable Positive Stable Positive Negative Watch Positive

1 As of December 31, 2024. In March 2025, S&P revised HEI’s outlook to “Positive” from “Negative” and affirmed the “B-” issuer credit rating.

Note: The above ratings reflect only the view, at the time the ratings are issued or affirmed, of the applicable rating agency, from whom an explanation of the significance of such ratings may be obtained. Such ratings are not recommendations to buy, sell or hold any securities; such ratings may be subject to revision or withdrawal at any time by the rating agencies; and each rating should be evaluated independently of any other rating.

The Company’s credit rating downgrades related to the Maui windstorm and wildfires will continue to adversely impact its ability to access lower cost sources of capital. Through the sale of common stock in September 2024, the Company has raised sufficient cash to pay the first installment of the settlement of wildfire tort claims expected to be made no sooner than early 2026. The Company is currently working with its financial advisors on a financing plan to raise the additional capital required to fund its remaining 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. The potential damages and losses related to the Maui windstorm and wildfires and related lawsuits (see further information in Note 2 of the Consolidated Financial Statements), the suspension of dividends from Hawaiian Electric, the economic impact of higher fuel prices, inflation, higher interest rates, tightening of monetary policy and geopolitical situations, create significant uncertainty, and the Company cannot predict the extent or duration of these conditions, the future effects that these conditions will have on the Company’s financing plan, cost of capital and its ability to access additional capital, or the future impacts on the Company’s financial position, results of operations, and cash flows.

See Item 1A. Risk Factors for further discussion of risks and uncertainties. See “Credit ratings” in Hawaiian Electric’s MD&A for Hawaiian Electric’s credit ratings. The downgrades of HEI’s and Hawaiian Electric’s credit ratings impacted the Company’s ability to access lower cost sources of capital.

On September 25, 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 and will be used to fund the Company’s contribution to the expected Maui wildfire tort litigation settlement and for general corporate purposes.

On September 19, 2024, HEI filed a shelf registration statement with the SEC for 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.

There were no new issuances of common stock through the HEIRSP 401(k) Plan in 2025, 2024 or 2023 and HEI satisfied the share purchase requirements of the HEIRSP 401(k) Plan through open market purchases of its common stock. There were no new issuances of common stock through the Dividend Reinvestment Program (DRIP) from January 1, 2023 through September 4, 2023, December 6 through December 31, 2023, in 2025 or in 2024 and HEI satisfied the share purchase requirements of the DRIP through open market purchases of its common stock. From September 5 through December 5, 2023, HEI satisfied the share purchase requirements of the DRIP through new issuances of approximately 0.5 million shares of common stock, amounting to $6.6 million, primarily for participants receiving the September 2023 dividend payment.

Off-balance sheet arrangements. Although the Company and the Utilities have certain off-balance sheet arrangements, management has determined that it has no off-balance sheet arrangements that either have, or are reasonably likely to have, a current or future effect on the Company’s and the Utilities’ financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors, including the following types of off-balance sheet arrangements:

1.obligations under guarantee contracts,

2.retained or contingent interests in assets transferred to an unconsolidated entity or similar arrangements that serve as credit, liquidity or market risk support to that entity for such assets,

3.obligations under derivative instruments, and

41

4.obligations under a material variable interest held by the Company or the Utilities in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company or the Utilities, or engages in leasing, hedging or research and development services with the Company or the Utilities.

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.

Material estimates that are particularly susceptible to significant change include the amounts reported for pension and other postretirement benefit obligations; contingencies and litigation; income taxes; regulatory assets and liabilities; and asset retirement obligations (AROs). Management considers an accounting estimate to be material if it requires assumptions to be made that were uncertain at the time the estimate was made and changes in the assumptions selected could have a material impact on the estimate and on the Company’s results of operations or financial condition.

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 the policies discussed below 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. The policies affecting both of the Company’s two principal segments are discussed below and the policies affecting just one segment are discussed in the respective segment’s section of “Material estimates and critical accounting policies.” Management has reviewed the material estimates and critical accounting policies with the HEI Audit & Risk Committee and, as applicable, the Hawaiian Electric Audit & Risk Committee.

For additional discussion of the Company’s accounting policies, see Note 1 of the Consolidated Financial Statements and for additional discussion of material estimates and critical accounting policies, see the electric utility discussion below under the same heading.

Pension and other postretirement benefits obligations. The Company’s benefit obligations and reported costs of providing retirement benefits are dependent upon numerous factors resulting from actual plan experience and assumptions about future experience. For example, retirement benefits costs are impacted by actual employee demographics (including age and compensation levels), the level of contributions to the plans, earnings and realized and unrealized gains and losses on plan assets, and changes made to the provisions of the plans. Costs may also be significantly affected by changes in key actuarial assumptions, including the expected return on plan assets, the discount rate and mortality. The Company’s accounting for retirement benefits under the plans in which the employees of the Utilities participate is also adjusted to account for the impact of decisions by the PUC. Changes in obligations associated with the factors noted above may not be immediately recognized as costs on the income statement, but generally are recognized in future years over the remaining average service period of plan participants.

The discount rate used to calculate the Company’s benefit obligations is a significant assumption that affects the Company’s benefit obligations. As of December 31, 2025, the discount rates for HEI and the Utilities’ pension and other benefits plans were 5.78% and 5.67%, respectively. Based on various assumptions in Note 11 of the Consolidated Financial Statements, sensitivities of the projected benefit obligation (PBO) and accumulated postretirement benefit obligation (APBO) as of December 31, 2025, associated with a change in the discount rate, were as follows and constitute “forward-looking statements”:

(dollars in millions)

Pension benefits

Other benefits

Discount rate +/-50 $(6)/$7 $(6)/$7

Also, see Notes 1 and 11 of the Consolidated Financial Statements.

Contingencies and litigation. The Company is subject to proceedings (including PUC proceedings), lawsuits and other claims. Management assesses the likelihood of any adverse judgments in or outcomes of these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is based on an analysis of each individual case or proceeding, often with the assistance of outside counsel. The required reserves may change

42

in the future due to new developments in each matter or changes in approach in dealing with these matters, such as a change in settlement strategy.

In general, environmental contamination treatment costs are charged to expense, unless it is probable that the PUC would allow such costs to be recovered through future rates, in which case such costs would be capitalized as regulatory assets. Also, environmental costs are capitalized if the costs extend the life, increase the capacity, or improve the safety or efficiency of property; the costs mitigate or prevent future environmental contamination; or the costs are incurred in preparing the property for sale.

As a result of the Maui windstorm and wildfires, HEI and Hawaiian Electric evaluated various financing plans to pay the amounts included in the tort-related Settlement Agreements and determined that paying in four equal annual installments is the most viable option and aligns with the Companies’ expectations of how the settlement amount will be paid. As of December 31, 2025, the Utilities have recorded a settlement accrual of $1.92 billion which reflects their best estimate of the loss contingency. In addition, as a result of executing final settlement agreements in its securities class action and shareholder derivative lawsuits, as of December 31, 2025, HEI recorded a settlement accrual of $47.8 million, and concurrently, 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. Refer to “Recent Developments” and Note 2 of the Consolidated Financial Statements for more information.

See Notes 1, 2 and 4 of the Consolidated Financial Statements.

Income taxes. Deferred income tax assets and liabilities are established for the temporary differences between the financial reporting bases and the tax bases of the Company’s assets and liabilities using tax rates expected to be in effect when such deferred tax assets or liabilities are realized or settled. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.

In 2024, the Company generated a $287.1 million capital loss from the sale of ASB. For federal tax purposes, any excess capital loss is first carried back three years and then carried forward for up to five years to offset future capital gains. For Hawaii state tax purposes, unused capital losses can only be carried forward for up to five years, with no carryback option available. Since capital losses can only be offset against capital gains, the Company believes it is more likely than not that the tax benefit of the capital loss on the sale of ASB will not be realized, because there is no expectation of generating capital gains and no tax strategies in place to produce capital gains before the loss expires. As of December 31, 2025, the Company’s federal and Hawaii capital loss carryforward is $273.1 million and $289.4 million, respectively, with a valuation allowance totaling $66.1 million for federal and state, related to the capital loss.

In 2024, the Company agreed to settle the Maui windstorm and wildfires tort-related legal claims on a global basis. This nonrecurring settlement will create a net operating loss (NOL) of approximately $1.878 billion, resulting in a total deferred tax asset (DTA) of $483.7 million. The Company analyzed the positive and negative evidence of each source of taxable income that will allow the DTA to be realized as enumerated in ASC 740. Other than the capital loss carryforward discussed above, the Company expects to fully utilize current DTAs that will be generated over the next 17-year period for HEI consolidated and 13-year period for Hawaiian Electric consolidated, based on estimated income projections (exclusive of future reversals of taxable temporary differences). The Company believes that the DTA generated from the nonrecurring settlement, along with historical DTAs, will be fully utilized, with the exception of the capital loss carryforward. The Company has generated consistent earnings over the past three years exclusive of the nonrecurring settlement. The Company believes that it is more likely than not that the Company will realize the benefits of its gross DTAs, other than the capital loss carryforward, including the $483.7 million DTA recognized as a result of the settlement. If estimated future income projections turn out to be lower, it should be noted that the DTA related to the NOL carryforward does not expire.

Management evaluates its potential exposures from tax positions taken that have or could be challenged by taxing authorities. These potential exposures result because taxing authorities may take positions that differ from those taken by management in the interpretation and application of statutes, regulations and rules. Management considers the possibility of alternative outcomes based upon past experience, previous actions by taxing authorities (e.g., actions taken in other jurisdictions) and advice from its tax advisors. Management believes that the Company’s provision for tax contingencies is reasonable. However, the ultimate resolution of tax treatments disputed by governmental authorities may adversely affect the Company’s current and deferred income tax amounts.
