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

Restoration costs and recoveries. The Utilities are continuing restoration work to rebuild portions of the electric system in Lahaina to ensure safe and reliable power to all West Maui customers. Restoration efforts include the rebuilding of transmission and distribution lines along former routes in the Lahaina area with the installation of new interim steel poles and electrical equipment. To date, power has been restored to all customers that were able to have power restored in Lahaina and the rest of West Maui.

On December 27, 2023, the Public Utilities Commission of the State of Hawaii (PUC) issued an order authorizing deferred accounting treatment for the Utilities’ incremental non-labor expenses related to the Maui windstorm and wildfires. The deferred accounting treatment applies to certain non-labor expenses incurred from August 8, 2023 through December 31, 2024 that are not already a part of the base rates. The approval pertains only to deferred cost treatment; any cost recovery of deferred costs will be the subject of a separate application(s). As of June 30, 2024, the Utilities have deferred $30.2 million of certain incremental costs related to the Maui windstorm and wildfires to a regulatory asset.

While the Utilities plan to seek recovery of damage to covered electrical infrastructure under their property insurance programs, the timing and amount of any insurance recoveries are not determinable at this time and as such, an insurance receivable has not been recorded as of the date of this filing. The Company’s property insurance has a total policy limit of $500 million with a $1 million retention for damages related to Utility-owned non-generating assets, including overhead transmission and distribution assets within 1,000 feet of such assets. The Utilities believe capital expenditures related to restoration that are not covered by insurance will be managed under their current regulatory mechanisms, the recovery of which would be subject to PUC approval.

Tort-related legal claims. As of August 8, 2024, HEI and the Utilities have each been named in approximately 700 lawsuits related to the Maui windstorm and wildfires. These civil and class action lawsuits have been filed in the Maui and Oahu Circuit Courts against HEI, the Utilities, and other defendants, including the County of Maui, the State of Hawaii and related state entities, private landowners and developers, and telecommunications companies (collectively, tort-related legal claims). Two class actions are also pending in federal court. Most of these lawsuits allege that the defendants were responsible for, and/or negligent in failing to prevent or respond to the wildfires that led to the property destruction and loss of life. Other claims include, among other things, personal injury, wrongful death, emotional distress and inverse condemnation. One lawsuit asserting similar theories and claims was filed by the County of Maui against HEI and the Utilities, one lawsuit was filed by Spectrum Oceanic, LLC against HEI and the Utilities and other defendants, and other lawsuits were filed by approximately 160 subrogation insurers against HEI, the Utilities, a private landowner, and telecommunications companies. Additional lawsuits may be filed against the Company and other defendants in the future. The plaintiffs seek to recover damages and other costs, including punitive damages. Defendants have asserted cross-claims against one another for indemnification, contribution, and subrogation.

Various unaffiliated third parties have published estimates of the total economic damage generally ranging from $3.8 billion to $6 billion. These estimates have not been validated by the Company, and they represent gross numbers that do not take into account causation or liability and do not attempt to allocate responsibility among the various defendants. As such, these estimates are not intended to provide a range of a reasonably possible loss in excess of the recorded amount under ASC Topic 450-20, “Loss Contingencies” attributable to the Company arising from the Maui windstorm and wildfires. In addition, on November 6, 2023, the Hawaii Insurance Division of the State of Hawaii Department of Commerce and Consumer Affairs released preliminary data on Maui windstorm and wildfires claims, and the Hawaii Insurance Division has subsequently provided updated data to include estimated losses for commercial property and business interruption. Through June 30, 2024, the data collected from over 200 insurers indicated estimated total insured losses of $3.3 billion for residential, commercial, personal, and other property, and business interruption. The estimated total losses for insured claims related to residential property includes homeowners insurance, dwelling-fire landlord, condominium unit owner, renters insurance, and other residential property. The estimated total losses do not account for uninsured or underinsured property losses, interest, attorneys’ fees, fire suppression and clean-up costs, evacuation costs, personal injury or wrongful death damages, medical expenses or other costs, such as potential punitive damages, fines or penalties. It is uncertain whether the insured claims reported to the Hawaii Insurance Division are complete, and together with property damage claims unaccounted for, as mentioned above, the total amount of property damage claims could be materially higher than the amount reported by the Hawaii Insurance Division. The Hawaii Insurance Division did not state whether it intends to provide updated information in the future.

The Company is actively working with the State of Hawaii and others in the community on solutions for Maui’s recovery, including the compensation of those who suffered losses in the Maui windstorm and wildfires and who are currently named as plaintiffs in the various cases. On November 8, 2023, Hawaii Governor Josh Green announced the One ‘Ohana Initiative (the One ‘Ohana Initiative) as a collective path forward to recovery from the Maui windstorm and wildfires. The One ‘Ohana Initiative is a new humanitarian aid fund of $175 million, with the objective to compensate, in an expedited manner, those who have lost loved ones and those who have suffered severe injuries in the Maui windstorm and wildfires. The One ‘Ohana Initiative provides an alternative to a lengthy and expensive legal process. Beneficiaries who have lost loved ones are anticipated to receive payments of $1.5 million per decedent, and those who suffered severe injuries are expected to share in a specially allocated pool of compensation. In exchange for receiving such a payment, beneficiaries will be required to waive their ability to pursue legal claims for wrongful death and severe injuries. Hawaiian Electric fully supports this humanitarian initiative and has contributed $75 million. The Governor announced that other parties, including the State of Hawaii, the County of Maui, and Kamehameha Schools have all agreed to contribute to the fund. Hawaiian Electric’s contribution to the Initiative was less than half of the total, and Hawaiian Electric's insurance carriers funded its share of the contributions to the fund. Hawaiian Electric’s contribution is reflective of its commitment to join with community partners to provide solutions to promote Maui’s recovery. Hawaiian Electric’s commitment to contribute to the One ‘Ohana Initiative is not an admission of guilt or reflection of fault or liability related to the wildfires. Under the One ‘Ohana Initiative, all claimants (except families of missing persons) were required to submit a completed registration form and registrants who meet the Fund’s eligibility requirements then were required to complete and submit a claim form. As of the claim-submission deadline of July 15, 2024, 35 claim forms were received that relate to death claims and 12 claim forms were received that relate to physical injury claims.

On August 2, 2024, attorneys representing the individual and class plaintiffs reached an agreement in principle with all defendants to settle all of their tort-related legal claims in the litigation arising out of the Maui windstorm and wildfires. The agreement in principle was the product of a mediation process that lasted several months and remains subject to final documentation and court approval. Under the agreement in principle, HEI and Hawaiian Electric, the State of Hawaii, the County of Maui, Kamehameha Schools, West Maui Land Co., Hawaiian Telcom and Spectrum/Charter Communications have agreed to contribute a total of approximately $4.04 billion to one or more funds that would pay the claims of those who filed

The agreement in principle does not resolve claims with insurers who have asserted subrogation claims in separate lawsuits, and such insurers are not parties to the agreement in principle. However, the agreement in principle provides that the definitive settlement agreement must provide for resolution of all subrogation claims by insurers that have been or could be brought against defendants arising out of the Maui windstorm and wildfires for no additional consideration. The agreement in principle includes a condition to the defendants’ obligations providing that within 90 days from its execution, either (a) insurers that have brought claims arising out of the Maui windstorm and wildfires enter into a written agreement that provides for releases of all claims against the defendants, or (b) that a trial court enters an order providing that if the final definitive agreement between the plaintiffs and the defendants becomes effective, then those same insurers’ exclusive remedy for any claims against the defendants would be limited to asserting liens against the settlement amounts obtained by the individual plaintiffs (so long as the order becomes final and unappealable within nine months from its date of issuance or, in that time period, those same insurers agree to provide the requisite releases).

Of the total settlement amount, HEI and Hawaiian Electric would contribute a total of $1.99 billion, which includes as a credit towards that amount the $75 million previously contributed for the One ‘Ohana Initiative, to be paid in four equal annual installments, with the first installment expected to be made no earlier than mid-2025. While the agreement in principle remains subject to final documentation and court approval, the Utilities have accrued their best estimate of the loss of approximately $1.71 billion, which represents the best estimate of the lump sum amount to settle claims with the plaintiffs as of June 30, 2024. The agreement in principle contains no admission of any liability by HEI or the Utilities and reflects the collective efforts of the State, HEI and the Utilities, and other defendants to seek a comprehensive resolution of the litigation arising out of the Maui windstorm and wildfires. The Utilities will seek insurance recovery to partially mitigate the potential financial impact; however, the timing and amount of any insurance recoveries are not determinable at this time.

As part of the agreement in principle, the parties agreed to vacate all trial dates and stay the litigation, except for litigation activities between the individual plaintiffs and the subrogation insurers and actions taken to further settlement. On August 2, 2024, the Second Circuit court overseeing the Special Proceeding in which most of the individual plaintiff actions have been coordinated vacated the trial dates that previously had been set. Accordingly, no trial dates are currently set in any action. No stay of litigation has been agreed to in the subrogation actions, but no trial dates have been set in those actions.

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

Securities class action and shareholder lawsuits. On August 24, 2023, a putative securities class action captioned Bhangal v. Hawaiian Electric Industries, Inc., et al., No.: 3:23-cv-04332-JSC (the Securities Action) was filed in the United States District Court for the Northern District of California. The lawsuit alleges violations of the Securities Exchange Act of 1934 (the Exchange Act) and Rule 10b-5 promulgated thereunder against HEI and certain of its current and former officers (collectively, Defendants), and Section 20(a) of the Exchange Act against certain of HEI’s current and former officers. Plaintiff broadly alleges that Defendants made materially false and misleading statements or omissions regarding HEI’s wildfire prevention and safety protocols and related matters. Plaintiff seeks unspecified monetary damages. On December 7, 2023, the court appointed Daniel Warren as lead plaintiff and Pomerantz LLP as lead plaintiff’s counsel. On March 8, 2024, the lead plaintiff filed an amended complaint. The Company has filed a motion to dismiss that complaint and intends to vigorously defend against this action. There is no assurance that the Company will be successful in the defense of the litigation or that insurance will be available or adequate to fund any potential settlement or judgment or the litigation costs of the action. The Company does not believe that a loss is probable and any possible loss or range of loss is not reasonably estimable.

On September 11, 2023, a putative shareholder derivative action captioned Rice v. Connors, et al., No. 1CCV-23-0001181 was filed in the Circuit Court of the First Circuit, State of Hawaii. On December 6, 2023, the case was removed to the United States District Court for the District of Hawaii and captioned Rice v. Connors, et al., No. 1:23-cv-00577-JAO-BMK. On March 14, 2024, the United States District Court remanded the case to the Circuit Court of the First Circuit, State of Hawaii. This action is purportedly brought by a shareholder on behalf of nominal defendants HEI and Hawaiian Electric against certain current and former officers and directors of HEI and Hawaiian Electric. Plaintiff asserts Hawaii state law breach of fiduciary duty, abuse of control, corporate waste, unjust enrichment, and aiding and abetting breach of fiduciary duty claims allegedly arising in connection with the Maui windstorm and wildfires that occurred in August 2023 and certain of the Company’s prior

public disclosures. Plaintiff seeks, on behalf of HEI and Hawaiian Electric, compensatory and punitive damages, restitution, disgorgement, and equitable relief in the form of changes to corporate governance, policies and culture. HEI has moved to stay the proceeding pending resolution of the tort-related legal claims and the Securities Action. While the Company has obligations to indemnify and/or advance the defendants’ legal fees and costs in connection with this lawsuit, any monetary recovery in the derivative litigation should accrue to the Company. The Company is unable to predict the ultimate outcome and is unable to make a reasonable estimate of the amount or range of loss, if any, that could result from any unfavorable outcome.

Kallaus v. Johns, et al., No. 3:23-cv-06627 (the Kallaus Action), Cole v. Johns, et al., No. 3:24-cv-00598 (the Cole Action), and Tai v. Seu, et al., No. 3:24-cv-01198 (the Tai Action). On March 19, 2024, upon stipulation by the parties, the court consolidated the Kallaus Action, the Cole Action, and the Tai Action under the caption In Re Hawaiian Electric Industries, Inc. and Hawaiian Electric Company, Inc. Derivative Litigation, No. 3:23-cv-06627 (the Consolidated Derivative Actions). On June 19, 2024, Plaintiffs filed a consolidated amended complaint. The Consolidated Derivative Actions are purportedly brought by shareholders of HEI on behalf of nominal defendants HEI and Hawaiian Electric against certain current and former officers and directors of HEI and Hawaiian Electric. Plaintiffs purport to assert both Hawaii state law and federal securities law claims. Plaintiffs assert state law breach of fiduciary duty, corporate waste, unjust enrichment, gross mismanagement, and abuse of control claims purportedly arising in connection with the Maui windstorm and wildfires that occurred in August 2023 and certain public disclosures. Plaintiffs also assert claims under Section 10(b) of the Exchange Act, and Rule 10b-5 promulgated thereunder, and generally allege that the Company and certain of its current and former officers made materially false and misleading statements or omissions regarding the Company’s wildfire prevention and safety protocols and related matters. Plaintiffs seek, on behalf of HEI and Hawaiian Electric, unspecified monetary and punitive damages, disgorgement, and other relief. HEI moved to stay the Consolidated Derivative Actions pending resolution of the tort-related legal claims and the Securities Action, and also moved to dismiss the consolidated amended complaint for failing to adequately allege that the Board’s refusal of the plaintiffs’ demands was wrongful. While the Company has certain obligations to indemnify and/or advance the defendants’ legal fees and costs in connection with this lawsuit, any monetary recovery in the Consolidated Derivative Actions should accrue to the Company. The Company is unable to predict the ultimate outcome and is unable to make a reasonable estimate of the amount or range of loss, if any, that could result from any unfavorable outcome.

Assad v. Seu, et al., No. 1:24-cv-00164 (the Assad Action), and Faris v. Seu, et al., No. 1:24-cv-00247 (the Faris Action). On July 3, 2024, upon stipulation by the parties, the court consolidated the Assad Action and Faris Action under the caption In Re Hawaiian Electric Industries, Inc., Stockholder Derivative Litigation, No. 1:24-cv-00164 (the Hawaii Federal Derivative Actions). Both actions are purportedly brought by shareholders on behalf of nominal defendant HEI and against certain current and former officers and directors of HEI and Hawaiian Electric. Plaintiffs purport to assert Hawaii state law claims for breach of fiduciary duty, corporate waste, and unjust enrichment allegedly arising in connection with the Maui windstorm and wildfires that occurred in August 2023 and certain public disclosures. Plaintiffs generally allege that the Company and certain of its current and former officers made materially false and misleading statements or omissions regarding the Company’s wildfire prevention and safety protocols and related matters. Plaintiffs seek, on behalf of HEI, compensatory damages, restitution, disgorgement, injunctive relief, and equitable relief, including in the form of changes to HEI’s corporate governance policies and procedures. On July 30, 2024, upon HEI’s motion, the court stayed the Hawaii Federal Derivative Actions pending resolution of the motion to dismiss the Securities Action and the motions to stay and dismiss the Consolidated Derivative Actions. While the Company has obligations to indemnify and/or advance the defendants’ legal fees and costs in connection with this lawsuit, any monetary recovery in the derivative litigation should accrue to the Company. The Company is unable to predict the ultimate outcome and is unable to make a reasonable estimate of the amount or range of loss, if any, that could result from any unfavorable outcome.

Maui windstorm and wildfires costs. Legal costs in connection with the litigation and loss contingencies are expensed as incurred. The Company has $165 million of excess liability insurance and $25 million of miscellaneous professional liability insurance for third party claims, including claims related to wildfires, with a retention of $0.3 million and $1.0 million, respectively, and $145 million directors and officers liability insurance to cover claims related to the shareholder and derivative lawsuits, with a retention of $1.0 million. As of June 30, 2024, the Company’s and Utilities’ insurance receivable totaled $34.8 million and $29.6 million, respectively, under the policies. As of June 30, 2024, HEI and its subsidiaries have approximately $41 million, $25 million and $133 million of insurance coverage remaining under the excess liability, miscellaneous professional liability and directors and officers liability policies, respectively.

On May 4, 2024, HEI and the Utilities reached an agreement to settle indemnification claims asserted by the State of Hawaii without any admission of fault or responsibility. Under the terms of the agreement, HEI and the Utilities agreed to contribute up to $18.4 million through the end of 2024 related to the costs of the professional advisors engaged by the State of Hawaii to advise on a variety of matters related to the Maui windstorm and wildfires. Under certain circumstances, HEI and the Utilities have the unilateral right to terminate the agreement and stop paying the costs for future periods. As of June 30, 2024, a total of $10.6 million of such costs were accrued and reflected in Maui windstorm and wildfires related expenses-Other expense in the table above. HEI and the Utilities are seeking insurance recoveries for such costs; however, the timing and amount of any insurance recoveries are not determinable at this time.
