PBR Supports Stable, Predictable Revenues Driven by 3 Main Sources 7 Incremental earnings opportunities under PBR Illustrative Total • ARA spending below inflationary adjustment Annual Revenue Adjustment (ARA) • Annual inflationary adjustment Total Earnings Separate RecoveryIncremental ARA Earnings PIMs Earnings ARA Spend • Baseline O&M & baseline capex • Exceptional Project Recovery Mechanism (EPRM) • Innovative pilot projects • Renewable Energy Infrastructure Program (REIP) • Performance incentive mechanisms Incremental Earnings Under PBR 1 2 3
Formulaic Annual Revenue Adjustments Provide Visibility, With Mechanism to Recover Costs from Unpredictable Exogenous Events Annual revenue adjustment formula: i-factor x-factor z-factor customer dividend Accounts for annual inflation • Measured by Gross Domestic Product Price Index (GDPPI) from Blue Chip Economic Indicators forecast as of October of each year • October 2025 forecast for 2026: 2.8% Productivity factor • Initially set at 0% (where it currently remains) Ex post opportunity to recover costs for exogenous events • Review and approval determined on case-by- case basis • Example: COVID-19- related costs recovered through Z-Factor • Potential mechanism for storm cost recovery (e.g., Hurricane Lala) Three components: (i) 0.22% adjustment ~Compounds over time. The 2026 amount is $14.6M. (ii) Management audit savings commitment made in Hawaiian Electric 2020 rate case, approved by PUC at $6.6M annually (iii) ERP benefits returned to Hawai‘i Electric Light and Maui Electric customers. 2026 amount in effect is $3.3M 8 • Annual target revenues set with ARA during each 5-year Multi-year Rate Period (MRP) • PUC to examine modifications to the ARA in Phase 6 of the PBR Proceeding for implementation in MRP2
Hawaiian Electric Crews Responded Rapidly Despite Hurricane Lala’s Severity 9 • Hawaiian Electric crews responded rapidly • Although outages, at their peak, impacted over 40% of customer accounts across the utility’s service territories, utility crews made rapid progress restoring service, with more than 95% of affected customers restored by August 19 • Hawaiian Electric is strengthening the grid while repairing damage • As storm-damaged power lines are replaced, the utility is strengthening the electric system where possible • In high wildfire risk areas, copper wire is being replaced with aluminum wire during restoration and repair work • O&M impact from Hurricane Lala estimated at $15 – $20 million1. Lala O&M, along with O&M from the Kona Low storms earlier in the year, totals $25 – $30 million1 and is being assessed for recovery • Approximately 20% – 25%1 of the total storm O&M estimated may be deemed non-incremental and ineligible for recovery • In addition to O&M storm costs for Lala and Kona Lows, capex spend related to the storms is currently estimated at $30 – $40 million1 • The Company is planning to file a cost deferral application in 2026, followed by an application for recovery once all costs are finalized 41.6% 24.7% 7.8% 4.1% 2.8% 1.4% 0 20 40 60 80 100 120 140 1.0 2.0 3.0 4.0 5.0 6.0 HECO - Oahu HELCO - Hawaii Island MECO - Maui County % of statewide customers affected 16-Aug 17-Aug 18-Aug 19-Aug 20-Aug 23-Aug Efforts of Hawaiian Electric crews resulted in accelerated restoration despite severe damage C u s to m e rs i m p a c te d • Hurricane Lala caused extensive statewide damage as it passed through the southern portion of the island chain August 14 – 16 • Severity of damage resulted in Presidential emergency declaration signed August 25 1. Restoration and damage assessment activities are ongoing, and the amounts presented reflect management's estimates as of September 4, 2026 based on information currently available. Actual total costs may differ materially from these estimates and such estimates do not factor in potential insurance coverage. Whether, and to what extent, the Company defers storm costs as a regulatory asset and ultimately recovers from customers depends on a review and approval by the PUC. The Company can give no assurance that recovery will be authorized, or that it will be authorized in the amounts, on the timeline, or on the terms requested. A disallowance or delay could have a material adverse effect on the Company's financial condition, results of operations, and cash flows.
10 Alternative Rate Rebasing Advancing, With Tentative Schedule Released PHASED INCREASE PROVIDES FOR GRADUAL BILL IMPACT TENTATIVE SCHEDULE, WITH COMPANY- PROPOSED INTERIM DECISION IN DECEMBER $83.2 $125.0 $169.8 $46.9 $5.1 $44.8 GDPPI adjustment Insurance expenses O&M reductions Total 2027 increase 2028 Depreciation adjustment Total increase requested 2027+2026 July 17 Rebasing application re- submitted in new docket (2026-0162) December 18 Company’s proposed date for an interim decision (allowing new rates to go into effect on January 1, 2027) September Public hearings commence, followed by intervention deadline Mid to late April Commission- proposed final Track 11 D&O based on preliminary procedural schedule Following D&O Commission Order initiating Track 21 1. The PUC has bifurcated the re-basing proceeding into two tracks: Track 1 is focused on determining the revenue requirement that will form the basis for target revenues at the start of MRP2. Track 2 will focus on updating revenue allocation and rate design in accordance with updated class load information and cost-of-service analysis (see PUC Order No. 41575).
Modifying forecasted GDPPI inflation adjustment • Base the inflation adjustment on actual rather than forecasted inflation, and better reflect actual inflationary pressures in our unique island operating environment • Use a blended index that incorporates the utility labor cost index Revising PIM Portfolio • Ensure target performance is within the company's control to achieve, and limit number of PIMs to avoid dilution of effort and focus while ensuring PIMs cover core objectives • Expand reward potential to fulfill PUC's original intent3 that they provide a meaningful opportunity. Proposing up to 200 bps at risk (downside of 50 bps / upside of 150 bps) Terminate Subtractive ARA Components • Eliminate the Management Audit Savings Commitment, 22 bps customer dividend, and return of ERP Benefits through Customer Dividend Additional • Expand scope of EPRM to allow recovery for large “business-as-usual” costs; Revise approved cost of capital in future EPRM projects to reflect higher risk; Pension and OPEB tracker modifications4 11 Additional Revenue-Enhancing Opportunities to be Pursued in Phase 6 PUC’s Guidance on PBR Phase 6 • Proceeding to examine specific PBR mechanisms to determine what modifications should be adopted heading into MPR2 • Stated focus is on Performance Incentive Mechanism (PIM) portfolio, Customer Dividend and collective revenue opportunities offered by the X-Factor and EPRM1 • Phase 6 will resume following resolution of alternative rate rebasing proposal2 1. As stated in PUC Decision and Order No. 41876. 2. As stated in PUC Decision and Order No. 42351. 3. Proposed 200 bps structure directly implements PUC staff’s original recommendation for “between three and six PIMs that, in total, would provide the HECO Companies with incentives that would increase or decrease earnings by 150 - 200 basis points.” (Staff Proposal for Updated Performance-Based Regulations, filed on February 7, 2019 in Docket No. 2018-0088). 4. Modifications contemplated include adding 401(k) costs to the tracker, and eliminating unamortized balances at the end of each calendar year to avoid the need to reset tracker balances for amortization purposes at the end of MRP2. Our Phase 6 Objectives Include:
12 Our Affordability Strategies Target Total Energy Burden 3.24% of monthly household income • Total household energy burden considers Hawaiʻi’s unique energy landscape and its broader statewide goals, including: • Second most electrified state in the U.S. • Highest penetration of rooftop solar • Second highest EV adoption per capita • Second highest number of persons per household • In 2025, Hawaiʻi’s total household energy burden ranked 4th lowest among all U.S. states • Hawaiʻi is one of four states whose electricity costs decreased from 2024 to 2025 HAWAI’I HOUSEHOLD ENERGY BURDEN IS LOWER THAN THE NATIONAL AVERAGE 2.54% of monthly household income 2025 Hawai’i total household energy burden1 89% 77% 9%22% 2% 2% 1. Household energy burden is calculated as household energy spending (retail electricity sales + retail natural gas sales + levelized cost of residential solar) divided by the number of total households, as a percentage of median household income.

Includes installations from 1/1/24 through 7/31/26.
Multiple Stakeholders Have Taken “Whole-of-Society” Approach to Wildfire Risk Reduction 16 • Act 303: Allows State Fire Council to amend Fire Code to require owners / occupants of property located in hazardous fire areas to maintain effective fire breaks and practice other fire prevention activities • Act 302: Addresses priorities from Fire Safety Research Institute Phase 3 report (Jan 14, 2025) • Established formal Office of the State Fire Marshal (appointed June 2025) • Statewide risk assessment, oversight of fire code development & enforcement • Develops training standards for prevention, inspection & suppression • Develops wildfire hazard map identifying risk zones • Requires biennial statistical reports L E G IS L AT IO N GOVERNOR STATEW ID E E F F O R T S • Approved 40 Remote Automatic Weather Stations • Began installations with federal partners, of a total of 80 fire-detection sensors with 24-hour altering capabilities • Continued collaborations with federal partners, nonprofit organizations and local communities • Revamped siren protocols in conjunction with counties • Reestablished a state Fire Marshal (Act 302) • 2025 Budget: $450M+ for statewide wildfire mitigation response • 20 full-time employee brushfire positions for Hawaii Emergency Management Agency • $24.7M in other federal funds and $7M in general funds for hazard mitigation and emergency operations center • Department of the Hawaiian Homelands added $20M for wildfire response, recovery, and prevention measures • $7.4 million in general funds for fire response and rehabilitation and fuels reduction contracts for DLNR’s Division of Forestry and Wildlife (DOFAW) • $10M in general funds for fire and emergency response equipment for DOFAW • $2.4M for Maui for fire prevention, erosion control and fire suppression dip tanks Whole-of- society efforts reduce statewide wildfire risk
17 Wildfire Mitigation Plan (WMP) Costs Approved Securitization Ensures Critical Work Done at Least Cost to Customers $270 $80 $350 Total WMP Costs Approved O&M Capital $18.5 $240.5 $82.7 $8.6 • EPRM approval ensures cost recovery, with securitization planned to minimize bill impact • Approved cost covers capital and O&M • Additional approval received for recovery of up to $11.5 million of 2025 WMP O&M2, and $3.9 million of annual ongoing WMP O&M in 2028+ • Affordability remains our focus, and planned securitization ensures customer affordability while allowing critical investments to continue Grid Hardening Operational Practices Situational Awareness Other1 $350M 1. Includes costs for wildfire risk analytics, strengthening stakeholder and community partnerships, and wildfire management and governance. 2. $11.5 million of estimated incremental 2025 O&M was approved by the PUC for deferral and subsequent recovery. The utility’s incremental 2025 O&M incurred was $9.6 million, which was recorded to a regulatory asset as of December 31, 2025. The utility will therefore recover the actual expenses incurred of $9.6 million.
18 Safety is a Core Value at the Forefront of All We Do 1. Total Case Incident Rate measures how many work-related injuries and illnesses occur per 100 employees. TCIR is calculated as follows: The number of Occupational Safety and Health Administration (OSHA) recordable cases multiplied by 200,000 productive hours (i.e. 2,000 work-hours per year per employee multiplied by 100 employees) divided by the total number of productive hours for the year. 2. Lost Time Rate measures any occupational injury or illness which results in an employee being unable to work a full assigned work shift after an incident per 100 employees. LTR is calculated according to OSHA guidelines as follows: the number of Lost Time cases (injury or illness which an employee is unable to work a full assigned work shift as a result of a work-related injury or illness) multiplied by 200,000 productive hours (i.e. 2,000 work- hours per year per employee multiplied by 100 employees) divided by the total number of productive hours for the year. 3.

Cap and methodology to be determined by the PUC • Authorizes securitization to finance $500 million of infrastructure resilience costs, including wildfire safety improvements, supporting customer affordability of critical investments • Directs PUC to conduct a study examining establishment and implementation of a wildfire recovery fund (completed 12/31/25) LIMITING CUSTOMER BILL IMPACTS OF WILDFIRE INVESTMENTS Act 258 PROTECTING UTILITY’S ABILITY TO PROCURE AFFORDABLE CLEAN ENERGY Act 191 • Supports contracted renewable projects by allowing the state to provide a financial backstop for renewables developers ‒ “Step-in” agreements ensure project owners receive payment, improving project economics and supporting customer affordability • Supports developers’ access to reasonably-priced capital, protecting ability to reach State’s clean energy targets HELPING MAUI WILDFIRE TORT LITIGATION SETTLEMENT MOVE FORWARD Act 301 • Appropriates money to fund the State of Hawaii’s settlement of claims related to the Maui wildfire tort litigation settlement ‒ Critical step in ensuring the settlement can move forward, and that the State’s $807 million obligation is fully funded
How Do Separate Recovery Mechanisms Work? • EPRM: Provide specific revenue requirements for each project. Revenues are accrued with minimal lag, starting the first day of the month following project completion ‒ Total revenue requirement (RR) for each project consists of a capital revenue requirement and an expense revenue requirement ‒ RR = O+T+D+r(RB); Operating expenses + taxes + depreciation + return on rate base • Pilot Projects: Intended to foster innovation by establishing an expedited implementation process for pilots that test new technologies, programs and business models. The utility can submit specific proposals and the PUC will target issuing a decision within 45 days, otherwise the proposal is considered approved as submitted ‒ Allows utility to defer and recover total annual expenditures, subject to an annual cap of $10M, over twelve months 36

Status of Key Open Dockets 39 Subject and Description Docket # Latest Developments Next Milestone Performance-based regulation Proceeding to evolve regulatory framework to better align with customer interests and state clean energy policy 2018-0088 Beginning in 2024, this docket has focused on (a) whether - and if so, by what process - the utility’s rates should be rebased before the beginning of the next PBR multiyear rate period to commence in 2027 (“MRP2”), and (b) whether modifications to the PBR Framework were warranted for MRP2. On 2/27/2025, the PUC issued an order establishing that the utility may rebase rates with a 2026 test year consolidated rate case type proceeding. On 8/13/2025, the PUC issued an order providing process guidance for development of proposed PBR Framework modifications (PBR proceeding “Phase 6”), including potential party-proposed changes to the Annual Revenue Adjustment (“ARA” mechanism, EPRM mechanism and the PIMs portfolio). On 8/28/2025, the utility filed a request to extend the time to file a rate case to allow collaboration among the PBR Working Group parties on an alternative rate rebasing proposal that could eliminate the need for a general rate case application and process. The PUC approved the request on 9/29/25 and noted that if the parties were unsuccessful in developing an alternative rebasing proposal, or if such a proposal were submitted and rejected by the PUC, the utility can file a 2027 test year rate case type proceeding in the second half of 2026. The PUC also noted that, depending on outcome of the alternative rate rebasing process, the PUC may defer the start of MRP2 beyond January 2027. On 3/6/2026, the utility filed an alternative rebasing proposal jointly with PBR Working Group party Ulupono Initiative. The rebasing request proposed an increase in revenues of $170 million, which represents a consolidated increase of 5.3% compared to total operating revenues at current effective rates. In an order issued on 6/15/2026, the PUC directed the utility to re-submit its request for an increase in its revenue requirement, with supporting materials, in the form of a new application, and established a tentative procedural schedule for the new proceeding. On 6/25/2026, the utility’s filed a motion for reconsideration of the PUC’s 6/15/2026 order regarding the rejection of the utility’s reservation of rights provision and the procedural schedule established in the order. Phase 6 of the PBR proceeding will commence to vet and fully develop modifications to the PBR Framework for MRP2, followed by, as necessary, statements of position, workshops, discovery, briefing, and an evidentiary hearing. Further guidance from the PUC on Phase 6 is expected. Order from the PUC addressing the utility’s motion for reconsideration of the PUC’s 6/15/2026 order. Alternative re-basing 2026-0162 In accordance with the PUC’s order in Docket No. 2018-0088, the utility filed its application for approval of its rebasing proposal on 7/17/2026. Awaiting a procedural schedule from the PUC for review of the utility’s application for approval of its rebasing proposal (as the PUC’s 6/15/2026 tentative procedural schedule was issued prior to the utility’s 7/17/2026 submittal.

On 4/13/2026, the utility filed the 2026-2027 WMP Update. On 6/15/2026, the PUC issued an order regarding the updated Procedural Schedules that shall govern the review of utility’s: (1) Compliance with year 2025 of its WMP; and (2) 2026-2027 WMP Update. TBD 2025-2027 Wildfire Safety Strategy (referred to as the “2025-2027 WMP”) Exceptional Project Recovery Mechanism (EPRM) 2025-0263 On 5/30/2025, the utility submitted an application requesting PUC approval to commit approximately $350 million from 2025-2027 for capital investment ($270 million) and O&M ($80 million) for its 2025-2027 WMP and to recover these costs through the EPRM. On 1/14/2026, the PUC issued an order authorizing deferred accounting treatment for the utility’s 2025 O&M expenses (incurred between June and December 2025) to implement the utility’s 2025-2027 WMP. On 6/25/2026, the PUC issued a decision and order approving the utility’s application, including: (1) the commitment of up to $350 million in funds for its 2025-2027 WMP Project; (2) approval of cost recovery through the EPRM of: (a) up to $350 million in 2025-2027 Project costs; and (b) up to $3.9 million per year (plus 3% escalation) in post-2027 implementation O&M. The EPRM cost recovery approval includes WMP costs of $350 million, and includes recovery of the $9.6 million in O&M expenses deferred from 2025 (as the PUC’s Order approved recovery of up to $11.5 million in such expenses). The utility is prohibited from effectuating cost recovery for any of the approved Project costs through the EPRM until the PUC has issued an Order addressing the utility’s forthcoming securitization application for a financing order pursuant to HRS §269G-2. All Project costs that are approved for cost recovery through securitization shall not be recoverable through the EPRM. Any approved Project costs that may be deemed ineligible for recovery through securitization may be recovered through the EPRM. Given language in the decision and order that the utility is prohibited from effectuating cost recovery through the EPRM until the PUC has issued an order addressing the utility’s forthcoming securitization application, the utility is focusing its efforts on updating its securitization application for filing targeted in third quarter of 2026.

(Hawaiian Electric) and their subsidiaries contain “forward-looking statements,” which include statements that are predictive in nature, depend upon or refer to future events or conditions and usually include words such as “will,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “predicts,” “estimates” or similar expressions. In addition, any statements concerning future financial performance, ongoing business strategies or prospects or possible future actions are also forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties and the accuracy of assumptions concerning HEI and its subsidiaries (collectively, the Company), the performance of the industries in which they do business and economic, political and market factors, among other things. These forward-looking statements are not guarantees of future performance and actual results and financial condition may differ materially from those indicated in the forward-looking statements. • Risks, uncertainties and other important factors that could cause actual results to differ materially from those described in forward-looking statements and from historical results include, but are not limited to, the following: • the potential for further trade policy changes under the current administration could disrupt our supply chains and increase costs, e.g., the Utilities’ capital goods and equipment purchases and those of its independent power producers (IPPs) that contain components, sub-components, or raw materials sources from outside the U.S. could experience increases in costs, which could threaten the viability of projects and impact our ability to meet customer demand and the Utilities’ ability to achieve renewable portfolio standards (RPS) goals; • the impact of the Maui windstorm and wildfires, including potential liabilities in excess of settlement amounts and potential regulatory penalties, which may result in significant costs that may be unrecoverable (or not reimbursed on a timely basis) through insurance and/or rates; • an increase in insurance premiums and the inability to fully recover premiums through rates or the potential inability to obtain wildfire and general liability insurance coverage at reasonable rates, if available at all; • the ability to raise the amount of capital necessary on reasonable terms, if at all, for the Company’s and the Utilities’ contribution to the Maui wildfire tort litigation settlement in order to alleviate future conditions that may cause substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern; • potential further dilution to existing shareholders if the Company raises funds by issuing additional equity or equity-linked securities; • the inability to execute financing plans to alleviate future conditions that may cause substantial doubt about HEI’s and the Utilities’ ability to continue as a going concern prior to the issuance of their respective annual financial statements, which could result in an event of default and an acceleration of the Company’s and the Utilities’ debt and lead to filing for bankruptcy protection if waivers from lenders are not received; • extreme weather events, including windstorms and other natural disasters, particularly those driven or exacerbated by evolving climate dynamics, which could increase the risk of the Utilities’ equipment being damaged, becoming inoperable or contributing to a wildfire; • future suspension, material reduction or extended delay in dividends or other distributions from operating subsidiaries to HEI; • further downgrades by credit rating agencies in their ratings of the securities of HEI and Hawaiian Electric and their impact on results of financing efforts; • the risks of suffering losses and incurring liabilities that are uninsured (e.g., damages to the Utilities’ transmission and distribution system and losses from business interruption) or underinsured (e.g., losses not covered as a result of insurance deductibles or other exclusions or exceeding policy limits), and the risks associated with the operation of transmission and distribution assets and power generation facilities, including public and employee safety issues, and assets causing or contributing to wildfires; • international, national and local economic and political conditions—including the state of the Hawaii tourism, defense and construction industries; the strength or weakness of the Hawaii and continental U.S. real estate markets; decisions concerning the extent of the presence of the federal government and military in Hawaii; the implications and potential impacts of federal government shutdowns, including the impact to the Utilities’ customers’ ability to pay their electric bills and the impact on the State of Hawaii economy; the implications and potential impacts of U.S. and foreign capital and credit market conditions and federal, state and international responses to those conditions; the potential impacts of global and local developments (including global economic conditions and uncertainties, unrest, terrorist acts, wars, conflicts, political protests, deadly virus epidemic or other crisis); the effects of changes that have or may occur in U.S. policy, such as with respect to immigration and trade; and pandemics; • the ability to adequately address risks and capitalize on opportunities related to the Company’s and the Utilities’ sustainab ility priority areas, which include safety, reliability and resilience, including relating to wildfires and other extreme weather events, decarbonization, economic health and affordability, secure digitalization, human capital management, employee engagement, and climate-related risks and opportunities; • citizen activism, including civil unrest, especially in times of severe economic depression and heightened social and political divisions, which could negatively impact customers and employees, impair the ability of the Company and the Utilities to operate and maintain their facilities in an effective and safe manner, and citizen or stakeholder activism that could delay the construction, increase project costs or preclude the completion of third-party or Utility projects that are required to meet electricity demand, resilience and reliability objectives and RPS and other climate-related goals; • the effects of actions or inaction of the U.S. government or related agencies, including those related to the U.S. debt ceiling or budget funding, monetary policy, trade policy, energy and environmental policy, and other policy and regulatory changes advanced or proposed by the current administration;

• the potential delay by the Public Utilities Commission of the State of Hawaii (PUC) in considering (and potential disapproval of actual or proposed) proposals related to rate rebasing, performance-based regulation (PBR), wildfire safety, renewable energy or grid resiliency, among others, and related costs; reliance by the Util ities on outside parties such as the State, IPPs and developers; supply-chain challenges; and uncertainties surrounding technologies, solar power, wind power, biofuels, liquefied natural gas, environmental assessments required to meet RPS and other climate-related goals; the impacts of implementation of the wildfire mitigation, renewable energy and resilience proposals on future costs of electricity and potential penalties imposed by the PUC for delays in the commercial operations of renewable energy projects; • the ability of the Utilities to develop, execute and recover the implementation costs of the Utilities’ action plans included in their Integrated Grid Plan, which was accepted by the PUC in 2024, due to the recent issuance of the PUC’s 2024 Inclinations on the Future of Energy in Hawaii, Governor Josh Green’s Executive Order No. 25-01, Accelerating Hawaii’s Transition Toward 100 Percent Renewable Energy, and the Hawaii State Energy Office’s Alternative Fuel, Repowering and Energy Transition Study on the aforementioned plans of the Util ities; • the ability of the Utilities to recover undepreciated cost of fossil fuel generating units, if they are required to be retired before the end of their expected useful life; • capacity and supply constraints or difficulties, especially if generating units (utility-owned or IPP-owned) fail or measures such as demand-side management, distributed generation, combined heat and power or other firm capacity supply-side resources fall short of achieving their forecasted benefits or are otherwise insufficient to reduce or meet peak demand; • high and/or volatile fuel prices, which increases working capital requirements and customer bills, or delivery of adequate fuel by suppliers (including as a result of the Iran war, Russia-Ukraine war and conflicts in the Middle East), which could affect the reliability of utility operations, and the continued availability to the Utilities of their Energy Cost Recovery Clauses (ECRCs); • the continued availability to the Utilities or modifications of other cost recovery mechanisms, including the Purchased Power Adjustment Clauses (PPACs), annual revenue adjustment (ARA) and pension and postretirement benefits other than pensions (OPEB) tracking mechanisms, and the continued decoupling of revenues from sales to mitigate the effects of declining kilowatt-hour sales; • the ability of the Utilities to recover increasing or additional costs (e.g., due to trade policies imposed by the current administration, tariffs, inflation, or other factors impacting prices) and earn a reasonable return on capital investments not covered by the ARA, while providing the customer dividend required by PBR; • the impact from the PUC’s modification of the PBR for the Utilities pursuant to Act 005, Session Laws 2018, including the potential changes to existing and/or addition of new Performance Incentive Mechanisms (PIMs), third-party proposals adopted by the PUC, and the implications of not achieving performance incentive goals; • the impact of fuel price levels and volatility on customer satisfaction and political and regulatory support for the Utilities; • unfavorable changes in economic conditions, such as sustained inflation, higher interest rates or recession, that negatively impact the ability of the Company’s customers to pay their utility bills and increase operating costs of the Utilities that cannot be passed on to, or recovered, from customers; • the risks associated with increasing reliance on renewable energy, including the availability and cost of non-fossil fuel supplies for renewable energy generation and the operational impacts and related cost impacts of adding intermittent sources of renewable energy to the electric grid; • the growing risk that energy production from renewable generating resources may be curtailed and the interconnection of additional resources will be constrained as more generating resources are added to the Utilities’ electric systems and as customers reduce their energy usage; • the ability of IPPs to deliver the firm capacity anticipated in their power purchase agreements (PPAs); • the potential that, as IPP contracts near the end of their terms, there may be less economic incentive for the IPPs to make investments in their units to ensure the availability of their units; • the ability of the Utilities to negotiate, periodically, favorable agreements for significant resources such as fuel supply contracts and collective bargaining agreements and avoid or mitigate labor disputes and work stoppages;

45 Explanation of HEI’s Use of Certain Unaudited Non-GAAP Measures HEI management uses certain non-GAAP measures to evaluate the performance of HEI. Management believes these non-GAAP measures provide useful information and are a better indicator of the companies’ core operating activities. Core earnings per share (EPS), core net income and other financial measures as presented here may not be comparable to similarly titled measures used by other companies. The accompanying tables provide a reconciliation of reported GAAP earnings to non-GAAP Core earnings. The reconciling adjustments from GAAP earnings to Core earnings are limited to the costs related to the Maui wildfires and costs related to the ongoing review of strategic options for Pacific Current. Management does not consider these items to be representative of the company’s fundamental Core earnings.
