HONOLULU - Hawaiian Electric Industries, Inc. (NYSE - HE) (HEI) today reported net income for the first quarter of 2026 of $30 million, or $0.18 per share, compared to net income of $27 million, or $0.15 per share in the first quarter of 2025. Excluding Maui wildfire-related expenses and expenses taken in connection with the review of strategic options for Pacific Current, Core1 net income was $31 million, or $0.18 per share, compared to $40 million, or $0.23 per share in 2025.

our first of four $479 million annual settlement payments. This marks a critical milestone for those who were impacted by the Maui wildfires, and our hearts continue to be with them as they continue on their path of collective healing,” said Scott Seu, HEI president and CEO.

“Utility core operations performed well despite elevated expenses related to multiple severe storms and historic flooding impacting the state in the first quarter. As we pivot from finalization of the settlement and navigate a transitional year ahead of our rate rebasing in 2027, we are expecting higher operations and maintenance expenses for the full year 2026. Our rate rebasing request is intended to address many of these higher costs, such as the increased insurance premiums we experienced over the last few years.

“Our utility continues to focus on reducing wildfire risk to our communities, and last month we submitted our updated Wildfire Mitigation Plan (WMP) covering 2026 and 2027. Moving forward, we’ll continue to focus on making the investments outlined in our WMP, while operating efficiently and maintaining financial strength. We’ll also continue to offer our customers support given affordability impacts from higher fuel prices due to geopolitical conflict,” said Seu.

Hawaiian Electric’s net income for the first quarter of 2026 was $35 million compared to net income of $48 million in the first quarter of 2025, with the decrease primarily driven by the following pre-tax items (among others):

•$19 million in higher O&M, driven by $7 million in higher storm response expenses, $6 million in higher insurance costs, $4 million in higher power supply costs and $3 million in higher transmission and distribution related expenses;

•$5 million in higher interest expense; and

•$2 million in higher depreciation expense.

These items were partially offset by (among others):

•$10 million in higher revenues, primarily from the annual revenue adjustment mechanism; and

•$2 million in higher interest income.

Hawaiian Electric’s Core net income for the first quarter was $36 million compared to $50 million in 2025.

Hawaiian Electric is expecting 2026 O&M expense, excluding pension, to significantly outpace inflation as we progress through a transitional year ahead of a 2027 rate rebasing. This is due to the following factors: higher insurance premiums, primarily reflecting the deferral treatment of wildfire insurance premiums prior to 2026; storm response expenses related to severe weather in February and March; higher vegetation management expenses as the utility prioritizes safety following record rainfall in the first quarter; higher overhauls and station maintenance expenses as the utility prioritizes reliability; higher IT related costs to improve cyber defenses; and higher labor and benefits costs. In addition, the maximum penalty is expected under the Fuel Cost Risk Sharing mechanism, which is recorded as a reduction of fuel revenue. Hawaiian Electric’s proposed rate rebasing is intended to address many of the higher O&M costs, such as increased insurance premiums.

The holding and other companies’ net loss was $5 million in the first quarter of 2026 compared to $21 million in the first quarter of 2025. The lower net loss for the quarter was primarily due to higher expenses in 2025 related to the strategic review of Pacific Current, and lower net interest expense following the retirement of holding company debt with ASB sale proceeds in April of 2025. Core net loss for the quarter was $5 million compared to $10 million in the same quarter of 2025, primarily due to lower net interest expense.

HEI announced leadership structure changes to reflect its pure-play utility focus following divestment of substantially all of its non-utility businesses. Effective June 1, Scott Seu, who has served as HEI President and CEO since 2022, will be CEO of both HEI and Hawaiian Electric. Shelee Kimura, who has served as Hawaiian Electric President and CEO since 2022, will be President of both companies. A recent decision by the Hawaii Public Utilities Commission enabled the simplified leadership structure.

“For 135 years, Hawaiian Electric has delivered electricity and innovations to improve daily life for families and communities throughout the islands we serve,” Seu said. “Now, with our unified enterprise dedicated to that mission, we’ll be more efficient as we continue our focus on empowering our customers, communities and state with safe, reliable, resilient and affordable power for generations to come.”

Results of operations for interim periods are not necessarily indicative of results to be expected for future interim periods or the full year 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 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 GAAP1 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 HEI’s ongoing review of strategic options for Pacific Current. Management does not consider these items to be representative of the company’s fundamental Core earnings.
