Performance Information

The Portfolio has not commenced operations as of the date of this Prospectus. The returns presented for the Portfolio reflect the performance of the Predecessor fund. It is anticipated that on or about December 4, 2026, the Portfolio will acquire all of the assets and liabilities of the Guardian Large Cap Disciplined Growth VIP Fund, a series of Guardian Variable Products Trust (the “Predecessor fund”) through a reorganization (the “Reorganization”). As a result of the Reorganization, the Portfolio will adopt the performance and financial history of the Predecessor fund. The Portfolio has a different investment goal, strategies, portfolio management team and contractual fees and expenses than the Predecessor fund. The performance figures have not been adjusted to reflect the Portfolio’s expenses. If the Predecessor fund’s performance information had been adjusted to reflect the Portfolio’s expenses, the performance may have been higher or lower for a given period depending on the expenses incurred by the Predecessor fund for that period.

The following bar chart illustrates the risks of investing in the Portfolio by showing changes in the Predecessor fund’s performance from calendar year to calendar year, and the table compares the Predecessor fund’s average annual returns to those of the Russell 1000^® Index (a broad-based securities market index) and Russell 1000^® Growth Index, which is relevant to the Portfolio because it has characteristics similar to the Portfolio’s investment strategies. Fees and expenses incurred at the contract level are not reflected in the bar chart or table. If these amounts were reflected, returns would be less than those shown. Of course, past performance is not necessarily an indication of how the Portfolio will perform in the future.
