Hawaiian Electric Industries (HE) shares fell 4.9% in afternoon trading Monday after the company revealed late Friday, along with its Q1 results, that it expects operations and maintenance costs to outpace inflation in 2026.

The company reported Q1 non-GAAP net income late Friday of $0.18 per diluted share, up from $0.15 a year earlier.

Revenue in the three months ended March 31 rose to $746.4 million from $744.1 million a year earlier.

Hawaiian Electric Industries expects 2026 operations and maintenance expenses, excluding pension, to outpace inflation as it navigates a transitional year ahead of a 2027 rate rebasing amid higher insurance premiums, storm response expenses, vegetation management expenses, and information technology-related and labor costs, it said.

The company also expects maximum penalty under the Fuel Cost Risk Sharing mechanism, it added.
