Portfolio Reorganization

The purpose of this Supplement is to notify of a portfolio reorganization. At its meeting held from March 23-26, 2026, the Board of Trustees for the John Hancock Variable Insurance Trust (“JHVIT”) approved a plan of reorganization for vote by affected policyowners. If the plan for reorganization is approved by policyowners, the reorganization will occur at the close of business on or about October 30, 2026 (“Reorganization Date”). On the Reorganization Date, the following “Acquired Portfolios” will be reorganized into the “Acquiring Portfolios”:

Accordingly, after October 30, 2026, the Lifestyle Balanced Portfolio – Series NAV, Lifestyle Growth Portfolio – Series NAV, and Lifestyle Moderate Portfolio – Series NAV will replace the Managed Volatility Balanced Portfolio – Series NAV, Managed Volatility Growth Portfolio – Series NAV, and Managed Volatility Moderate Portfolio – Series NAV, respectively. After that date, you will no longer be able to allocate policy value or premiums to the Managed Volatility – Series NAV Portfolios. Any policy value or premium allocated to a Managed Volatility – Series NAV Portfolio will be allocated to the corresponding Lifestyle – Series NAV Portfolio.

Please note the following information regarding the Reorganization:

You should read this supplement together with the prospectus for the Policy you purchased and retain both documents for future reference.
