INVESCO DB BASE METALS FUND Annual Guide to Performance and Strategy

For investors seeking exposure to the essential building blocks of global industry, the INVESCO DB BASE METALS FUND (DBB) offers an accessible solution. This annual review delves into DBB's performance and strategy for the fiscal year ending December 31, 2025, explaining how this Exchange Traded Fund (ETF) provides a liquid way to invest in industrial base metals without direct physical ownership.

Business Overview

DBB tracks the price movements of the "DBIQ Optimum Yield Industrial Metals Index Excess Return™." This index uses an "Optimum Yield" strategy, a method designed to improve returns or reduce losses when the fund replaces expiring futures contracts with new ones – a process known as "rolling." Instead of simply buying the nearest-term contract, the strategy selects the futures contract with the most favorable implied "roll yield" from a range of eligible options. This aims to capture potential gains or minimize losses that can occur when futures prices differ across various expiration dates.

To gain this exposure, the fund primarily invests in futures contracts for a diversified group of base metals. DBB also holds U.S. Treasury bonds and high-quality money market instruments. These holdings serve two key purposes: they act as essential collateral for the futures contracts and generate additional income for the fund through interest.

Portfolio Holdings and Composition

As of November 10, 2025, the underlying index included futures contracts for:

• Aluminum
• Zinc
• Lead
• Nickel
• COMEX Copper
• Copper—Grade A

This mix directly exposes the fund to the global supply and demand forces affecting these crucial industrial commodities. Beyond these metal futures, the fund's portfolio also holds a significant portion of U.S. Treasury bonds and money market funds, which provide liquidity and collateral for its futures positions.

Financial Performance

For the fiscal year ended December 31, 2025, the fund reports its financial performance through several key metrics:

• Net Asset Value (NAV) Total Return: The percentage change in the fund's NAV, reflecting the performance of its underlying investments after expenses.
• Market Price Total Return: The percentage change in the fund's market price, which can differ from NAV due to the supply and demand for ETF shares.
• Benchmark Performance: A comparison of the fund's returns against its underlying index, the DBIQ Optimum Yield Industrial Metals Index Excess Return™, to assess how accurately it tracks the index.
• Net Investment Income (Loss): Income generated from interest on collateral holdings, minus operating expenses. For example, the Invesco Government & Agency Portfolio, part of its cash holdings, yielded approximately 3.68% in 2025, a decrease from 4.43% in 2024.
• Net Realized and Unrealized Gain (Loss) on Futures Contracts: The profit or loss from the fund's main investment activity.
• Net Increase (Decrease) in Net Assets from Operations: The overall change in the fund's net assets resulting from its investment activities and operations.

Costs and Expenses

Managing the fund incurs several costs that affect investor returns. Invesco Capital Management LLC, as the Managing Owner, oversees these operations. Key expenses include:

• Management Fee: The fund charges an annual management fee, typically a specific percentage of its average daily net assets. This fee covers administrative services and costs associated with the index provider (Deutsche Bank Securities, Inc.).
• Total Expense Ratio (TER): Investors should also consider the fund's Total Expense Ratio (TER), which represents the comprehensive annual cost of operating the fund, expressed as a percentage of its assets. This figure is critical for evaluating the fund's long-term performance.

The fund deducts these precise fee percentages from its assets. You can find them detailed in the fund's official prospectus and financial statements.

Financial Health and Liquidity

As of December 31, 2025, the fund reported approximately $117 million in assets under management (AUM). The fund's financial health primarily stems from its substantial asset base, which includes futures contracts and highly liquid U.S. Treasury bonds and money market instruments. These holdings provide the necessary collateral for its futures positions and ensure ample liquidity. The fund does not typically incur traditional corporate debt. Its financial stability directly links to the value of its underlying assets and its ability to manage its futures positions effectively. The strategy of holding U.S. Treasury bonds and money market funds is crucial for maintaining liquidity and generating interest income, which contributes to its overall financial resilience.

Competitive Position

The INVESCO DB BASE METALS FUND operates within a competitive landscape of commodity-focused exchange-traded products. Its competitive position is primarily defined by:

• Unique "Optimum Yield" Strategy: This strategy sets DBB apart from funds using a simple front-month futures approach, potentially offering a more favorable roll yield profile.
• Diversified Base Metal Exposure: The fund offers broad exposure to key industrial metals (Aluminum, Zinc, Lead, Nickel, Copper), providing a comprehensive solution for investors targeting this specific commodity segment.
• Liquidity and Accessibility: As an ETF, DBB provides easy trading on major exchanges, offering liquidity for investors.
• Expense Ratio: Its Total Expense Ratio (TER) relative to other base metal or broad commodity ETFs also influences its competitiveness.
• Assets Under Management (AUM): With approximately $117 million in AUM as of December 31, 2025, and 11.6 million shares outstanding as of January 31, 2026, DBB maintains a notable market presence, though it competes with larger, more broadly diversified commodity funds.

Key Risks for Investors

Investing in DBB involves specific risks that investors should carefully consider:

• Commodity Price Volatility: The fund's value is highly sensitive to fluctuations in global base metal prices, influenced by economic growth, industrial demand, supply disruptions, and geopolitical events.
• Futures Contract Risks:
  • Roll Yield (Contango/Backwardation): While the "Optimum Yield" strategy aims to mitigate this, futures markets can experience "contango" (where future prices are higher than spot prices), which can negatively impact returns as contracts are rolled. Conversely, "backwardation" (future prices lower than spot) can enhance returns.
  • Liquidity Risk: Futures markets can become illiquid, making it difficult to execute trades at desired prices without significantly affecting the market.
  • Counterparty Risk: The risk that a futures contract counterparty may default on its obligations, potentially leading to fund losses.
• Tracking Error Risk: The fund may not perfectly replicate the performance of its underlying index due to expenses, market inefficiencies, or operational factors.
• Concentration Risk: The fund's performance concentrates in a limited number of industrial base metals, making it susceptible to sector-specific downturns or events affecting these particular commodities.
• Regulatory and Tax Risks: Changes in regulations or tax laws related to commodities or ETFs could adversely affect the fund's operations or investor returns.
• Operational Flexibility: The fund has the flexibility to invest in other related metals or contracts if position limits are reached for specific metals. While this helps maintain market exposure, it introduces additional management discretion and potential for divergence from the primary index components.

Conclusion

The INVESCO DB BASE METALS FUND offers a targeted investment vehicle for those seeking exposure to the industrial base metals market. Its "Optimum Yield" strategy and diversified metal exposure aim to efficiently track commodity prices. However, investors must be aware of the inherent volatility of commodity markets, the complexities of futures investing, and the impact of fees on overall returns. For a comprehensive understanding before making investment decisions, a thorough review of the fund's complete 10-K filing, especially the detailed "Risk Factors" section (Item 1A), is essential.
