What Is HEI’s Growth Forecast?
HEI operates primarily in Hawaii, serving regulated utility customers across the islands and providing banking services concentrated in Hawaii's tourism- and real-estate-driven economy.
Regulated utility capex runway
Management targets roughly $1.5–2.0 billion of utility capital expenditures through 2028 focused on grid hardening, interconnection, storage, and wildfire mitigation, subject to regulatory approval and sequencing.
Revenue and rate-base trajectory
Revenue growth is expected to track prudent rate-base expansion under decoupling and cost-recovery mechanisms, with regulatory proceedings in 2024–2026 aimed at timely recovery of resiliency and risk-mitigation investments.
Legal overhang and liquidity actions
Legal and insurance developments from the 2023 Maui wildfires remain the primary overhang; the company suspended its common dividend in late 2023, tightened operating costs, and prioritized credit access to preserve liquidity while contesting causation and pursuing insurance recovery.
Banking subsidiary strength
American Savings Bank, with approximately $10–11 billion in assets, double-digit CET1, and a net interest margin around the low-3% area, provides earnings diversification and stable deposit funding in Hawaii's economy.
Financial outlook scenarios hinge on litigation outcomes, regulatory rate decisions, and the pace of capital deployment; analysts model paths where constructive cost recovery and contained legal exposure enable re-acceleration of regulated investment later in the decade.
Capital sources and leverage management
External funding may include project-level financing or tax equity for renewables and storage to moderate parent-level leverage and preserve credit metrics during the capex buildout.
Expense and litigation trajectory
Investors should expect elevated legal expenses and potentially staged resolutions across 2025–2026, with guidance likely conservative or withdrawn until material clarity emerges.
Utility ROE normalization drivers
Normalization of utility returns depends on rate case outcomes, wildfire cost treatment, and the timing of capital deployment; constructive regulatory treatment would restore ROE toward pre-2023 levels over time.
Consolidated liquidity and earnings
ASB's consistent earnings and deposit franchise support consolidated liquidity and can provide capital flexibility while the utility navigates regulatory and legal uncertainty.
Analysts' scenario framing
Scenarios generally bracket outcomes: constrained litigation exposure plus constructive cost recovery leads to re-accelerated regulated investment post-2025; adverse outcomes could defer capex and prolong conservative guidance.
Key financial metrics to monitor
Watch regulatory rate-case rulings, insurance recoveries, legal expense trends, ASB CET1 and net interest margin, and consolidated leverage and liquidity metrics for signs of directional change.
Practical implications for investors
Assess investment case using scenario-based valuation that incorporates litigation timing, regulatory recovery assumptions, and potential external financing to fund the $1.5–2.0 billion utility capex program through 2028. Review banking subsidiary metrics for downside support and liquidity.
- Monitor regulatory decisions in 2024–2026 affecting rate-base recovery
- Track legal developments and insurance recoveries tied to the 2023 wildfires
- Evaluate ASB capital ratios and net interest margin as earnings backstop
- Consider project financing and tax equity as mitigants to parent leverage

What Risks Could Slow HEI’s Growth?
Potential Risks and Obstacles for HEI center on wildfire liability and litigation outcomes, insurance recoveries, and evolving regulatory frameworks for catastrophic events; secondary risks span fuel-price exposure, supply-chain and interconnection delays for renewables, permitting hurdles, and grid resilience on islanded systems.
Wildfire liability and litigation risk
Litigation outcomes and settlement size can materially affect cash flow, credit metrics, and strategic flexibility; insurers and courts may limit recoveries, increasing direct utility exposure.
Regulatory and legislative uncertainty
Timing of cost recovery for resiliency and wildfire mitigation, changes to performance-based ratemaking, and updated interconnection standards could alter economics and project timelines.
Fuel-price and generation transition risk
Residual dependence on oil-fired generation exposes HEI to fuel-price volatility until firm renewables and storage scale; fuel costs can swing operating margins.
Supply-chain and interconnection delays
Delays for turbines, solar modules, batteries, and grid interconnection approvals can push out Stage 3 procurements and storage deployments, raising capital and schedule risk.
Permitting and community acceptance
Firm renewable projects require local permits and stakeholder buy-in; opposition can force redesigns, higher costs, or cancellations, affecting HEI market expansion plans.
Extreme-weather and islanded-grid resilience
Hawaii's island grids face concentrated climate risks; inadequate resilience increases outage costs and can trigger accelerated capital programs or regulatory penalties.
Financial and credit risks
Constrained external capital and higher borrowing costs could slow growth; suspended dividends change investor composition and may pressure stock valuation — HEI reported net debt/EBITDA trends to watch in 2024–25.
ASB-specific exposure
At ASB, credit and interest-rate risks could rise if Hawaii tourism or real estate soften, though capitalization remained relatively strong through 2024 based on public filings.
Technology and cyber risk
Grid digitization and advanced DER management increase cyberattack surfaces; a material outage or breach could trigger regulatory scrutiny and remediation costs.
Operational integration risk
Integrating high volumes of distributed energy resources and storage raises execution complexity; schedule slippage or underperformance on projects can impair HEI strategic plan delivery.
Key mitigations include multi-layer wildfire programs — grid hardening, vegetation management, protection-device settings — diversification into firm renewables and storage to lower fuel exposure, expanded demand response to manage peaks, and legal scenario planning; recent execution (coal retirement in 2022, commissioning 185 MW of grid-scale storage in 2023, expanded DER programs, and Stage 3 procurements) supports execution capability but schedule discipline, stakeholder engagement, and regulatory alignment will determine conversion of HEI Company growth strategy into durable growth.
