Stone Ridge Trust - LifeX 2030 Income Bucket ETF is a U.S.-domiciled, actively managed exchange-traded fund that seeks to provide fixed monthly distributions composed of Treasury interest income and return of principal through 2030. The fund invests primarily in debt securities issued by the U.S. Treasury; money market funds investing exclusively in U.S. Government Bonds; and repurchase agreements collateralized by U.S. Government Bonds. It is designed for investors seeking to address near-term spending needs through scheduled monthly cash flow, while retaining the ability to buy or sell shares in the secondary market. The fund expects to distribute substantially all of its assets by its 2030 end year, causing net asset value to decline over time as principal is returned. Shares trade under the ticker BCKT, with CUSIP 86172B585, and are issued by Stone Ridge Trust, a registered management investment company; investment management is provided by Stone Ridge Asset Management LLC. The fund operates in the United States fixed-income and U.S. government securities markets and is part of the LifeX Income Bucket ETF family, alongside the LifeX 2028 Income Bucket ETF and LifeX 2035 Income Bucket ETF. LifeX 2030 Income Bucket ETF was launched on September 24, 2025. Recent strategic developments include its September 2025 launch as part of Stone Ridge’s LifeX Income Bucket ETF platform, expanding the platform’s maturity-dated Treasury-based offerings for investors seeking predictable income-and-principal distributions through specified end years.
