Item 8.01

Other Events

Effective November 10, 2025, changes will be made to the DBIQ Optimum Yield Diversified Commodity Index Excess Return^TM (the “Index”), the index the Invesco DB Commodity Index Tracking Fund seeks to track. The changes to the Index are being implemented by Deutsche Bank AG, the Index provider. A summary of the changes are as follows:


1. Expanded Commodity Universe		• Eligible commodities will be determined annually based on their liquidity and economic importance. • Under the new methodology, the number of commodities included in the Index universe is expected to expand.

2. Modified Optimum Yield Methodology		• The current Optimum Yield methodology will be modified to eliminate contracts with limited liquidity.

3. Annual Review of Base Weights and Commodities		• The current static allocations to commodities will be changed by implementing a rules-based annual review to better reflect current global production and market liquidity.

4. Weight Limits (Annually at Rebalance)		• Implementation of sector and single commodity caps and floors to reduce concentration risk.

5. Intra-year Rebalancing Events		• An intra-year rebalance event will be triggered should a large deviation occur on a monthly observation date to help prevent significant deviations from annual rebalance target weights.

The changes described herein will not effect the Fund’s Investment Objective.
