C000262086 Investment Objective and Strategy

Putnam Sustainable Retirement 2070 Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Putnam Target Date Funds.

Investment objective

The fund seeks capital appreciation and current income consistent with a decreasing emphasis on capital appreciation and an increasing emphasis on current income as it approaches its target date.

Principal investment strategy

The funds asset allocation strategy may be attractive to investors who plan to retire or otherwise intend to begin making periodic withdrawals of their investments in or about 2070 (the target date). The fund is designed to provide diversification among different asset classes by investing its assets in other mutual funds and closed-end funds managed by the Investment Manager, or affiliates of the Investment Manager, which are referred to as underlying funds. The funds target allocations among asset classes and underlying funds will increasingly emphasize capital preservation and income over time and will change gradually based on the number of remaining years until the funds target date, as shown in the predetermined glide path in the chart under What are the funds and each underlying funds main investment strategies and related risks?.

The Investment Manager adjusts these allocations at the end of each calendar quarter based on the glide path. The following table presents your funds approximate allocations to each asset class and underlying fund as of February 27, 2026 and its projected approximate allocations to these asset classes and underlying funds as of February 26, 2027. By comparing the percentage allocations of your fund in the table, you can see how its allocations are expected to change during the one-year period beginning on February 27, 2026. The table also shows the approximate allocations of other Putnam Retirement Advantage Plus Funds, which are designed for investors with different target retirement dates. Over a five-year period, each funds allocations will gradually change to resemble the allocations of the fund with the next earliest target date.

The table illustrates how a funds allocations are expected to change over time to increasingly emphasize capital preservation and income.

In addition, because of rounding in the calculation of allocations among underlying funds and market fluctuations, actual allocations might be more or less than these percentages.

** Equity, fixed-income and alternatives allocations are hypothetical estimates based on an assumption that each Putnam Dynamic Asset Allocation Funds and Putnam Multi-Asset Income Funds allocation to equity and fixed income investments reflects its strategic allocations, an assumption that Putnam Dynamic Asset Allocation Equity Fund is equivalent to an equity investment, an assumption that Putnam Short Term Investment Fund is equivalent to a fixed income investment, and an assumption that each of Clarion Partners Real Estate Income Fund Inc. and Franklin BSP Lending Fund is equivalent to an alternatives investment. Actual allocations will vary. The funds target allocations may differ from the allocations shown in the table. The Investment Manager may change the glide path, the funds target allocations, and the underlying funds in which it invests at any time, although the Investment Manager expects these changes to be infrequent and generally in response to longer-term structural changes (i.e., in the average retirement age or life expectancy) that lead the funds portfolio managers to determine that a change is advisable.

It is assumed that investors will begin gradual withdrawals from the fund at or around the target date. As the target date year of the fund approaches, the funds target allocations will increasingly correspond closely to those of Putnam Retirement Advantage Plus Maturity Fund (Maturity Fund), a fund that seeks as high a rate of current income as the Investment Manager believes is consistent with preservation of capital, and the fund will be merged into Maturity Fund prior to the end of the target year as determined by the Investment Manager in its discretion. More information about Maturity Fund is available in this prospectus beginning on page 117 , and more information about the underlying funds (which are not offered by this prospectus) is included below and under What are the funds and each underlying funds main investment strategies and related risks ?
