Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • Global stock indexes and fixed income markets were broadly positive for the 12 months ended May 31, 2025. Many major central banks began easing interest rates early in the period as inflation slowed. Early optimism over the U.S. election of President Donald Trump brought, first, a boost to U.S. equities, followed by heightened volatility in global equity markets amid concerns over Trump’s fluctuating tariff policies.

  • Compared with the style-specific S&P Target Date 2040 Index, glide path effect contributed to results for the trailing one-year period. Despite volatility later in the period, global equity and fixed income markets advanced for the year amid optimism surrounding central bank interest rate cuts and solid corporate earnings, and the fund’s greater total equity exposure versus the benchmark was beneficial. Additionally, our diversified U.S. mid-cap equity structure added value, as our dedicated allocations to growth and value outpaced the benchmark’s core-oriented mid-cap equity allocation.

  • On the negative side, a leading detractor from relative results was security selection within the US Mid-cap Growth Equity Strategy, which trailed its benchmark. The fund’s structural exposure to real assets equities also detracted.

  • The fund seeks the highest total return over time consistent with an emphasis on both capital growth and income. The fund invests in a diversified portfolio of other T. Rowe Price stock and bond mutual funds that represent various asset classes and sectors. Its allocation among T. Rowe Price funds will change over time in relation to its target retirement date.

Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • Global stock indexes and fixed income markets were broadly positive for the 12 months ended May 31, 2025. Many major central banks began easing interest rates early in the period as inflation slowed. Early optimism over the U.S. election of President Donald Trump brought, first, a boost to U.S. equities, followed by heightened volatility in global equity markets amid concerns over Trump’s fluctuating tariff policies.

  • Compared with the style-specific S&P Target Date 2040 Index, glide path effect contributed to results for the trailing one-year period. Despite volatility later in the period, global equity and fixed income markets advanced for the year amid optimism surrounding central bank interest rate cuts and solid corporate earnings, and the fund’s greater total equity exposure versus the benchmark was beneficial. Additionally, our diversified U.S. mid-cap equity structure added value, as our dedicated allocations to growth and value outpaced the benchmark’s core-oriented mid-cap equity allocation.

  • On the negative side, a leading detractor from relative results was security selection within the US Mid-cap Growth Equity Strategy, which trailed its benchmark. The fund’s structural exposure to real assets equities also detracted.

  • The fund seeks the highest total return over time consistent with an emphasis on both capital growth and income. The fund invests in a diversified portfolio of other T. Rowe Price stock and bond mutual funds that represent various asset classes and sectors. Its allocation among T. Rowe Price funds will change over time in relation to its target retirement date.
