HAWAIIAN ELECTRIC INDUSTRIES INC 8-K

What Happened

• Hawaiian Electric Industries, Inc. (HE) filed a Current Report on Form 8-K on March 2, 2026 to provide updated descriptions of "Certain Material U.S. Federal Income Tax Considerations" related to its previously announced at-the-market (ATM) equity offering.
• The ATM Offering, established under an equity distribution agreement dated September 19, 2024, allows HE to offer and sell up to $250,000,000 of its common stock through sales agents. The updated tax descriptions are filed as Exhibit 99.1 and replace the equivalent section in the Prospectus Supplement filed September 19, 2024 (Registration Statement No. 333-282206).

Key Details

• Filing date: March 2, 2026 (Current Report on Form 8-K).
• ATM offering amount: up to $250,000,000 of common stock.
• Original ATM documentation: Prospectus Supplement and Registration Statement filed September 19, 2024 (File No. 333-282206).
• The updated tax discussion (Exhibit 99.1) supersedes the prior "Certain Material U.S. Federal Income Tax Considerations" text in the Prospectus Supplement.

Why It Matters

• Updated federal tax guidance can affect the after-tax treatment of transactions for investors and potential sellers of the common stock under the ATM program; anyone relying on the Prospectus Supplement should review the revised tax descriptions.
• This filing is a disclosure update—it does not itself issue shares but clarifies tax considerations for future sales under the ATM facility, and the 8-K constitutes an offer or solicitation relating to those securities.
