THE JUNE 10 SPECIAL MEETING IS JUST A FEW DAYS AWAY Ensure Significant Value for Your HEI Shares – Vote “FOR” Approval of the Merger Agreement with NextEra Energy A Transaction This Important Cannot Happen Without Your Support! DEAR FELLOW HEI SHAREHOLDER: Your vote “FOR” the proposed merger with NextEra Energy is extremely important. Combining with NextEra Energy provides substantial value for all HEI shareholders and will accelerate our goal of achieving a more affordable clean energy future for Hawai’i. However, these benefits can only be realized if the merger is approved. Your vote could be the difference. PLEASE VOTE ON-LINE OR BY PHONE – TODAY! Please take a moment to vote “FOR” the merger proposal today. You may vote quickly online or by phone by following the easy instructions provided in the email sent by your bank or broker. VOTE FOR SIGNIFICANT SHAREHOLDER VALUE! Upon the completion of the merger and the spinoff of ASB Hawaii, for each HEI share you own you will be entitled to receive 0.2413 shares of NextEra Energy common stock; 0.3333 shares of ASB Hawaii, the parent company of American Savings Bank; and a special cash dividend of $0.50 per share. Assuming 100 HEI shares owned and transaction completion in 2015, HEI shareholders would receive an estimated dividend of $150 in 2016 ($50 from the special dividend, $80 from NextEra Energy and $20 from ASB Hawaii) and a total dividend of $100 annually thereafter — and that’s before potential dividend growth. Over the past 10 years, NextEra Energy has consistently grown its dividends and adjusted earnings per share by an average of 8% per year and has achieved a 10-year total shareholder return of 300% — better than HEI. And while ASB Hawaii has contributed to your HEI dividends indirectly for years, after the merger and spinoff ASB Hawaii will pay dividends to you directly and expects those dividends to grow over time.
