PART I

Organization

PowerShares DB Energy Fund (the “Fund”), a separate series of PowerShares DB Multi-Sector Commodity Trust (the “Trust”), a Delaware statutory trust organized in seven separate series, was formed on August 3, 2006. DB Commodity Services LLC, a Delaware limited liability company (“DBCS” or the “Managing Owner”), seeded the Fund with a capital contribution of $1,000 in exchange for 40 General Shares of the Fund. The fiscal year end of the Fund is December 31^st. The term of the Fund is perpetual (unless terminated earlier in certain circumstances) as provided for in the Fourth Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”).

The Fund offers common units of beneficial interest (the “Shares”) only to certain eligible financial institutions (the “Authorized Participants”) in one or more blocks of 200,000 Shares, called a Basket. The proceeds from the offering of Shares are invested in the Fund. The Fund commenced investment operations on January 3, 2007. The Fund commenced trading on the American Stock Exchange (which became the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007 and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

As of the date of this Report, each of Deutsche Bank Securities Inc., Merrill Lynch Professional Clearing Corp., Newedge USA LLC, Virtu Financial Capital Markets LLC, Citigroup Global Markets Inc., J.P. Morgan Securities Inc., Credit Suisse Securities (USA) LLC, Virtu Financial BD LLC, Knight Capital Americas LLC, Timber Hill LLC, Morgan Stanley & Co. LLC, Jefferies LLC, Nomura Securities International Inc., RBC Capital Markets, LLC, UBS Securities LLC, Cantor Fitzgerald & Co., BNP Paribas Securities Corp., Goldman, Sachs & Co. and Goldman Sachs Execution & Clearing, L.P. has executed a Participant Agreement and are the only Authorized Participants.

Fund Investment Overview

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Energy Index Excess Return™ (the “DBIQ-OY Energy ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the energy sector. The commodities comprising the Index are light sweet crude oil, heating oil, brent crude oil, RBOB gasoline and natural gas (each an “Index Commodity”, and collectively, the “Index Commodities”).

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities included in the Index. The Index is comprised of futures contracts on each of the Index Commodities that expire in a specific month and trade on a specific exchange (the “Index Contracts”). If the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to any Index Commodity by investing in a specific Index Contract, the Fund may invest in (i) a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in (ii) other futures contracts not based on the particular Index Commodity ((i) and (ii) collectively, the “Alternative Futures Contracts”) if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with such Index Commodity. Please see http://www.dbxus.com with respect to the most recently available weighted composition of the Fund and the composition of the Index on the Base Date.

The Fund does not borrow money to increase leverage. As of December 31, 2013 and 2012, the Fund had $299,455,287 (or 100%) and $140,016,073 (or 100%), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker. Of this, $9,318,925 (or 3.1%) and $7,066,290 (or 5.05%), respectively, of the Fund’s holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund’s long futures positions. For additional information, please see the audited Schedule of Investments as of December 31, 2013 and 2012 for details of the Fund’s portfolio holdings.

Index Composition

The Index is composed of notional amounts of each of the underlying Index Commodities. The notional amount of each Index Commodity included in the Index is intended to reflect the changes in market value of each such Index Commodity within the Index. The closing level of the Index is calculated on each business day by the Index Sponsor based on the closing price of the futures contracts for each of the underlying Index Commodities and the notional amounts of such Index Commodities.

1

Table of Contents

The Index is rebalanced annually in November to ensure that each of the Index Commodities is weighted in the same proportion that such Index Commodities were weighted on June 4, 1990 (the “Base Date”). The Index has been calculated back to the Base Date. On the Base Date, the closing level was 100. The following table reflects the index base weights (the “Index Base Weights”) of each Index Commodity on the Base Date:

The composition of the Index may be adjusted in the event that the Index Sponsor is not able to calculate the closing prices of the Index Commodities.

The following table reflects the Fund weights of each Index Commodity or related futures contracts, as applicable, as of December 31, 2013:

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to each Index Commodity, the Fund employs a rule-based approach when it “rolls” from one futures contract to another. The Index replaces the underlying futures contracts on an “optimum yield” basis.

Rather than select a new futures contract based on a predetermined schedule (e.g., monthly), each Index Commodity rolls to the futures contract which generates the best possible “implied roll yield.” The futures contract with a delivery month within the next thirteen months which generates the best possible implied roll yield will be included in the Index. As a result, the Fund is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets for each Index Commodity, respectively.

In general, as a futures contract approaches its expiration date, its price will move towards the spot price in a contangoed market. Assuming the spot price does not change, this would result in the futures contract price decreasing and a negative implied roll yield. The opposite is true in a backwardated market. Rolling in a contangoed market will tend to cause a drag on an Index Commodity’s contribution to the Fund’s return, while rolling in a backwardated market will tend to cause a push on an Index Commodity’s contribution to the Fund’s return.

If the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to any Index Commodity by investing in a specific Index Futures Contract, the Fund may invest in Alternative Futures Contracts if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with an Index Contract. Please see http://www.dbxus.com with respect to the most recently available weighted composition of the Fund and the Fund’s Index on the Base Date.

The DBIQ Optimum Yield Energy Index is calculated in USD on both an excess return (unfunded) and total return (funded) basis.

The futures contract price for each Index Commodity will be the exchange closing price for such Index Commodity on each weekday when banks in New York, New York are open (the “Index Business Days”). If a weekday is not an Exchange Business Day (as defined in the following sentence) but is an Index Business Day, the exchange closing price from the previous Index Business Day will be used for each Index Commodity. “Exchange Business Day” means, in respect of an Index Commodity, a day that is a trading day for such Index Commodity on the relevant exchange (unless either an Index disruption event or force majeure event has occurred).

Table of Contents

On the first New York business day (the “Verification Date”) of each month, each Index Commodity futures contract will be tested in order to determine whether to continue including it in the Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month, known as the Delivery Month, a new Index Commodity futures contract will be selected for inclusion in the Index. For example, if the first New York business day is May 1, 2014, and the Delivery Month of the Index Commodity futures contract currently in such Index is June 2014, a new Index Commodity futures contract with a later Delivery Month will be selected.

For each underlying Index Commodity of the Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a Delivery Month (i) no sooner than the month after the Delivery Month of the Index Commodity futures contract currently in such Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is May 1, 2014 and the Delivery Month of an Index Commodity futures contract currently in the Index is June 2014, the Delivery Month of an eligible new Index Commodity futures contract must be between July 2014 and May 2015. The implied roll yield is then calculated and the futures contract on the Index Commodity with the best possible implied roll yield is then selected. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months prior to the Delivery Month is selected.

After the selection of the replacement futures contract, the monthly roll for each Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2^nd and 6^th Index Business Day of the month.

On each day during the roll period, new notional holdings are calculated. The calculations for the futures contracts on the old Index Commodities that are leaving the Index and the futures contracts on the new Index Commodities are then calculated.

On all days that are not monthly index roll days, the notional holdings of each Index Commodity future remains constant.

The Index is re-weighted on an annual basis on the 6^th Index Business Day of each November.

The calculation of the Index is expressed as the weighted average return of the Index Commodities.

Tax Reporting

The Fund has retained the services of PricewaterhouseCoopers LLP to assist with certain tax reporting requirements of the Fund and its Shareholders.

Regulation

Futures exchanges in the United States are subject to regulation under the CEAct by the CFTC, the governmental agency having responsibility for regulation of futures exchanges and trading on those exchanges. No U.S. governmental agency regulates the over-the-counter (the “OTC”) foreign exchange markets.

The CEAct and the CFTC also regulate the activities of “commodity trading advisors” and “commodity pool operators” and the CFTC has adopted regulations with respect to certain of such persons’ activities. Pursuant to its authority, the CFTC requires a commodity pool operator (such as the Managing Owner) to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend the registration of a commodity pool operator if the CFTC finds that the operator has violated the CEAct or regulations thereunder and in certain other circumstances. Suspension, restriction or termination of the Managing Owner’s registration as a commodity pool operator would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and might result in the termination of, the Fund. The CEAct gives the CFTC similar authority with respect to the activities of commodity trading advisors, such as the Managing Owner. If the registration of a managing owner as a commodity trading advisor were to be terminated, restricted or suspended, the managing owner would be unable, until such time (if any) as such registration were to be reinstated, to render trading advice to the Fund. The Fund is not registered with the CFTC in any capacity.

The CEAct requires all “futures commission merchants,” such as the Commodity Broker, to meet and maintain specified fitness and financial requirements, segregate customer funds from proprietary funds and account separately for all customers’ funds and positions, and to maintain specified books and records open to inspection by the staff of the CFTC.

The CEAct also gives the states certain powers to enforce its provisions and the regulations of the CFTC.

Shareholders are afforded certain rights for reparations under the CEAct. Shareholders may also be able to maintain a private right of action for certain violations of the CEAct. The CFTC has adopted rules implementing the reparation provisions of the CEAct which provide that any person may file a complaint for a reparations award with the CFTC for violation of the CEAct against a floor broker, futures commission merchant, introducing broker, commodity trading advisor, commodity pool operator, and their respective associated persons.

Pursuant to authority in the CEAct, the NFA was formed and registered with the CFTC as a “registered futures association.” At the present time, the NFA is the only non-exchange self-regulatory organization for commodities professionals. NFA members are subject to NFA standards relating to fair trade practices, financial condition, and consumer protection. As the self-regulatory body of the commodities industry, the NFA promulgates rules governing the conduct of commodity professionals and disciplines those professionals who do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity trading advisors, commodity pool operators, futures commission merchants, introducing brokers and their respective associated persons and floor brokers. The Commodity Broker and the Managing Owner are members of the NFA (the Fund itself is not required to become a member of the NFA).

The CFTC has no authority to regulate trading on foreign commodity exchanges and markets.

Employees

The Fund has no employees.

An investment in the securities of the Fund involves a high degree of risk. Investors should consider carefully all of the risks described below, together with the other information contained in this report and the Prospectus, before making a decision to invest in the securities of the Fund. If any of the following risks occur, the business, financial condition and results of operations of the Fund may be adversely affected.

Investment and Trading Related Risks

The Value of the Shares Relates Directly to the Value of the Futures Contracts and Other Assets Held by The Fund and Fluctuations in the Price of These Assets Could Materially Adversely Affect an Investment in The Fund’s Shares.

The Shares are designed to reflect as closely as possible the changes, positive or negative, in the level of the Index, over time, through its portfolio of exchange traded futures contracts on the Index Commodities. The value of the Shares relates directly to the value of its portfolio, less the liabilities (including estimated accrued but unpaid expenses) of the Fund. The price of the various Index Commodities may fluctuate widely. Several factors may affect the prices of the Index Commodities, including, but not limited to:

Net Asset Value May Not Always Correspond to Market Price and, as a Result, Baskets May be Created or Redeemed at a Value that Differs from the Market Price of the Shares.

The net asset value per Share will change as fluctuations occur in the market value of its portfolio. Investors should be aware that the public trading price of a Basket may be different from the net asset value of a Basket (i.e., 200,000 Shares may trade at a premium over, or a discount to, net asset value of a Basket) and similarly the public trading price per Share may be different from its net asset value per Share. Consequently, an Authorized Participant may be able to create or redeem a Basket at a discount or a premium to the public trading price per Share. This price difference may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares are closely related, but not identical to, the same forces influencing the prices of the Index Commodities, trading individually or in the aggregate at any point in time. Investors also should note that the size of the Fund in terms of total assets held may change substantially over time and from time-to-time as Baskets are created and redeemed.

Authorized Participants or their clients or customers may have an opportunity to realize a riskless profit if they can purchase a Basket at a discount to the public trading price of the Shares or can redeem a Basket at a premium over the public trading price of the Shares. The Managing Owner expects that the exploitation of such arbitrage opportunities by Authorized Participants and their clients and customers will tend to cause the public trading price to track net asset value per Share closely over time.

The value of a Share may be influenced by non-concurrent trading hours between the NYSE Arca and the various futures exchanges on which the Index Commodities are traded. While the Shares trade on the NYSE Arca from 9:30 a.m. to 4:00 p.m. Eastern Standard Time, the trading hours for the futures exchanges on which each of the Index Commodities trade may not necessarily

7

Table of Contents

coincide during all of this time. For example, while the Shares trade on the NYSE Arca until 4:00 p.m. Eastern Standard Time, liquidity in the global Light Sweet Crude Oil market will be reduced after the close of the NYMEX at 2:30 p.m. Eastern Standard Time. As a result, during periods when the NYSE Arca is open and the futures exchanges on which the Index Commodities are traded are closed, trading spreads and the resulting premium or discount on the Shares may widen and, therefore, increase the difference between the price of the Shares and the net asset value of the Shares.

Regulatory and Exchange Position Limits and Other Rules May Restrict the Creation of Baskets and the Operation of the Fund.

CFTC and commodity exchange rules impose speculative position limits on market participants, including the Fund, trading in certain commodities. These position limits prohibit any person from holding a position of more than a specific number of such futures contracts.

In the aggregate, the Index is composed of 5 Index Commodities, of which 4 Index Commodities are subject to speculative position limits imposed by either the CFTC or the rules of the futures exchanges on which the futures contracts for the applicable Index Commodities are traded. The purposes of speculative position limits are to diminish, eliminate or prevent sudden or unreasonable fluctuations or unwarranted changes in the prices of futures contracts. As of the date of this Report, the CFTC and commodity exchange rules impose speculative position limits on market participants trading in four of the five commodities included in the Index (Light Sweet Crude Oil, Heating Oil, RBOB Gasoline and Natural Gas, or the “Affected Index Commodities”). Currently, speculative position limits (i) for corn, oats, wheat, soybean, soybean oil and cotton are determined by the CFTC and (ii) for all other commodities are determined by the futures exchanges. Pursuant to the statutory mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, which was signed into law on July 21, 2010, the CFTC adopted final regulations on October 18, 2011, or the Regulations, which, in pertinent part, impose new federal position limits on futures and options on a subset of energy, metal, and agricultural commodities, or the Referenced Contracts, and economically equivalent swaps. The Regulations were to go into effect 60 days after the term “swap” is further defined pursuant to Section 721 of the Dodd-Frank Act. However, on September 28, 2012, a federal court issued an order vacating the Regulations. On November 5, 2013, the CFTC re-proposed for public comment new position limits and an aggregation rule both of which are currently pending and have not yet been adopted.

Generally, speculative position limits in the physical delivery markets are set at a stricter level during the spot month, the month when the futures contract matures and becomes deliverable, versus the limits set for all other months. If the Managing Owner determines that the Fund’s trading may be approaching any of these speculative position limits, the Fund may reduce its trading in that commodity or trade in other commodities or instruments that the Index Sponsor determines comply with the rules and goals of the Index. Below is a chart that sets forth certain relevant information, including current speculative position limits for each Affected Index Commodity that any person may hold, separately or in combination, net long or net short, for the purchase or sale of any commodity futures contract or, on a futures-equivalent basis, options thereon. Speculative position limit levels remain subject to change by the CFTC or the relevant exchanges.

Exchanges may also establish accountability levels applicable to futures contracts. An exchange may order a person who holds or controls aggregate positions in excess of specified position accountability levels not to further increase the positions, to comply with any prospective limit which exceeds the size of the position owned or controlled, or to reduce any open position which exceeds position accountability levels if the exchange determines that such action is necessary to maintain an orderly market.

Under current regulations, subject to any relevant exemptions, traders, such as the Fund, may not exceed speculative position limits, either individually or in the aggregate with other persons with whom they are under common control or ownership. Under the vacated Regulations, the CFTC would have required certain persons to aggregate exchange listed futures and economically equivalent swap positions owned or controlled by such persons.

Legend:

Because the Fund may be subject to position limits and, consequently, the Fund’s ability to issue new Baskets, or the Fund’s ability to reinvest income in additional futures contracts corresponding to the Affected Index Commodities, may be limited to the extent these activities would cause the Fund to exceed its applicable position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Shares. That is, the inability to create additional Baskets could result in Shares trading at a premium or discount to net asset value of the Shares.

Under the vacated Regulations, the CFTC, among other things, established speculative position limits on exchange listed futures and options on physical commodities (including certain energy, metals and agricultural products) and economically equivalent over-the-counter derivatives. Under the vacated Regulations, the CFTC also established aggregate position limits for certain other contracts based on the same underlying commodity, including certain contracts traded on non-U.S. exchanges. Depending on the outcome of any future CFTC or futures exchange rulemaking, as applicable, the rules concerning position limits may be amended in a manner that is detrimental to the Fund. For example, if the amended rules are detrimental to the Fund, its ability to issue new Baskets, or reinvest income in additional futures contracts corresponding to the Affected Index Commodities, may be limited to the extent these activities would cause the Fund to exceed the applicable position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Shares. That is, the inability to create additional Baskets could result in Shares in the Fund trading at a premium or discount to net asset value of the Shares.

The Fund’s Performance May Not Always Replicate Exactly the Changes in the Level of the Index.

It is possible that the Fund’s performance may not fully replicate the changes in the level of the Index due to disruptions in the markets for the Index Commodities, the imposition of speculative position limits or due to other extraordinary circumstances. As the Fund approaches or reaches position limits with respect to certain Index Contracts, the Fund may commence investing in other Alternative Futures Contracts if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with futures contracts that comprise the Index. In addition, the Fund is not able to replicate exactly the changes in the level of the Index because the total return generated by the Fund is reduced by expenses and transaction costs, including those incurred in connection with the Fund’s trading activities, and increased by interest income from the Fund’s holdings of short-term high credit quality fixed income securities. Tracking the Index requires trading of the Fund’s portfolio with a view to tracking the Index over time and is dependent upon the skills of the Managing Owner and its trading principals, among other factors.

The Fund Is Not Actively Managed and Tracks the Index During Periods in which the Index Is Flat or Declining as well as when the Index Is Rising.

The Fund is not actively managed by traditional methods. Therefore, if positions in any one or more of the Index Commodities are declining in value, the Fund will not close out such positions, except in connection with a change in the composition or weighting of the Index. The Managing Owner will seek to cause the net asset value of the Fund to track the Index during periods in which the Index is flat or declining as well as when the Index is rising.

The NYSE Arca May Halt Trading in the Shares Which Would Adversely Impact Your Ability to Sell Shares.

The Shares are listed for trading on the NYSE Arca under the market symbol “DBE.” Trading in the Shares may be halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of the NYSE Arca, make trading in the Shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules that require trading to be halted for a specified period based on a specified market decline. There can be no assurance that the requirements necessary to maintain the listing of the Shares will continue to be met or will remain unchanged. The Fund will be terminated if its Shares are delisted.

The Lack of an Active Trading Market for the Shares May Result in Losses on Your Investment in the Fund at the Time of Disposition of Your Shares.

Although the Shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the Shares will be maintained. If you need to sell your Shares at a time when no active market for them exists, the price you receive for your Shares, assuming that you are able to sell them, likely will be lower than that you would receive if an active market did exist.

The Shares Could Decrease in Value if Unanticipated Operational or Trading Problems Arise.

The mechanisms and procedures governing the creation, redemption and offering of the Shares have been developed specifically for this securities product. Consequently, there may be unanticipated problems or issues with respect to the mechanics of the operations of the Fund and the trading of the Shares that could have a material adverse effect on an investment in the Shares. In addition, although the Fund is not actively “managed” by traditional methods, to the extent that unanticipated operational or trading problems or issues arise, the Managing Owner’s past experience and qualifications may not be suitable for solving these problems or issues.

As the Managing Owner and its Principals have Been Operating Investment Vehicles like the Fund Since January 2006, their Experience may be Relatively Inadequate or Unsuitable to Manage the Fund.

The Managing Owner was formed to be the managing owner of investment vehicles such as the Fund and has been managing such investment vehicles since January 2006. The past performances of the Managing Owner’s management of other commodity pools are no indication of its ability to manage investment vehicles such as the Fund. If the experience of the Managing Owner and its principals is not relatively adequate or suitable to manage investment vehicles such as the Fund, the operations of the Fund may be adversely affected.

You May Not Rely on Past Performance or Index Results in Deciding Whether to Buy Shares.

Although past performance is not necessarily indicative of future results, the Fund’s performance history might (or might not) provide you with more information on which to evaluate an investment in the Fund. Likewise, the Index has a history which might (or might not) be indicative of the future Index results, or of the future performance of the Fund. Therefore, you will have to make your decision to invest in the Fund without relying on the Fund’s past performance history or the Index’s closing level history.

Fewer Representative Commodities May Result In Greater Index Volatility.

The Index is concentrated in terms of the number of commodities represented. The Fund is concentrated in 5 or fewer commodities. You should be aware that other commodities indexes are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities may result in a greater degree of volatility in an Index and the net asset value of the Fund which tracks the Index under specific market conditions and over time.

Price Volatility May Possibly Cause the Total Loss of Your Investment.

Futures contracts have a high degree of price variability and are subject to occasional rapid and substantial changes. Consequently, you could lose all or substantially all of your investment in the Fund.

The following table* reflects various measures of volatility** of the Index as calculated on an excess return basis:

Table of Contents

The following table reflects the daily volatility on an annual basis of the Index:

Daily Volatility: The relative rate at which the price of the Index moves up and down, found by calculating the annualized standard deviation of the daily change in price.

Monthly Return Volatility: The relative rate at which the price of the Index moves up and down, found by calculating the annualized standard deviation of the monthly change in price.

Average Annual Volatility: The average of yearly volatilities for a given sample period. The yearly volatility is the relative rate at which the price of the Index moves up and down, found by calculating the annualized standard deviation of the daily change in price for each business day in the given year.

Unusually Long Peak-to-Valley Drawdown Periods With Respect To the Index May Be Reflected in Equally Long Peak-to-Valley Drawdown Periods with Respect to the Performance of the Shares.

Although past Index levels are not necessarily indicative of future Index levels, the peak-to-valley drawdown periods that the Index has experienced have been unusually long and have lasted for multi-year drawdown periods.

Because it is expected that the Fund’s performance will track the change of its underlying Index, the Fund would suffer a continuous drawdown during the period that the Index suffers such a drawdown period, and in turn, the value of your Shares will also suffer.

Fees and Commissions are Charged Regardless of Profitability and May Result in Depletion of Assets.

The Fund is directly subject to the fees and expenses described herein which are payable irrespective of profitability. Such fees and expenses include asset-based fees of 0.75% per annum. Additional charges include brokerage fees of approximately 0.03% per annum in the aggregate and selling commissions. For the avoidance of doubt, selling commissions are not included in the Fund’s breakeven calculation. The Fund is expected to earn interest income at an annual rate of 0.05% per annum, based upon the yield on 3-month U.S. Treasury bills as of January 17, 2014. Because the Fund’s current interest income does not exceed its fees and expenses, the Fund will need to have a positive performance that exceeds the difference between the Fund’s interest income and its fees and expenses in order to break even. If the aggregate of the Fund’s performance and interest income do not exceed the Fund’s fees and expenses described herein, then the expenses of the Fund could, over time, result in losses to your investment therein. You may never achieve profits, significant or otherwise.

You Cannot Be Assured of the Managing Owner’s Continued Services, Which Discontinuance May Be Detrimental to the Fund.

You cannot be assured that the Managing Owner will be willing or able to continue to service the Fund for any length of time. If the Managing Owner discontinues its activities on behalf of the Fund, the Fund may be adversely affected.

Possible Illiquid Markets May Exacerbate Losses.

Futures positions cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as when foreign governments may take or be subject to political actions which disrupt the markets in their currency or major exports, can also make it difficult to liquidate a position.

There can be no assurance that market illiquidity will not cause losses for the Fund. The large size of the positions which the Fund may acquire increases the risk of illiquidity by both making its positions more difficult to liquidate and increasing the losses incurred while trying to do so.

You May Be Adversely Affected by Redemption Orders that Are Subject To Postponement, Suspension or Rejection Under Certain Circumstances.

The Fund may, in its discretion, suspend the right of redemption or postpone the redemption settlement date, (1) for any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) for such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. In addition, the Fund will reject a redemption order if the order is not in proper form as described in the participant agreement among the Authorized Participant, the Managing Owner and the Managing Owner in its capacity as managing owner of the Fund or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect a redeeming Authorized Participant. For example, the resulting delay may adversely affect the value of the Authorized Participant’s redemption proceeds if the net asset value of the Fund declines during the period of delay. The Fund disclaims any liability for any loss or damage that may result from any such suspension or postponement.

Because the Futures Contracts Have No Intrinsic Value, the Positive Performance of Your Investment Is Wholly Dependent Upon an Equal and Offsetting Loss.

Futures trading is a risk transfer economic activity. For every gain there is an equal and offsetting loss rather than an opportunity to participate over time in general economic growth. Unlike most alternative investments, an investment in Shares does not involve acquiring any asset with intrinsic value. Overall stock and bond prices could rise significantly and the economy as a whole prosper while Shares trade unprofitably.

Failure of Commodity Futures Markets to Exhibit Low to Negative Correlation to General Financial Markets Will Reduce Benefits of Diversification and May Exacerbate Losses to Your Portfolio.

Historically, commodity futures’ returns have tended to exhibit low to negative correlation with the returns of other assets such as stocks and bonds. Although commodity futures trading can provide a diversification benefit to investor portfolios because of its low to negative correlation with other financial assets, the fact that the Index is not 100% negatively correlated with financial assets such as stocks and bonds means that the Fund cannot be expected to be automatically profitable during unfavorable periods for the stock or bond market, or vice-versa. If the Shares perform in a manner that correlates with the general financial markets or do not perform successfully, you will obtain no diversification benefits by investing in the Shares and the Shares may produce no gains to offset your losses from other investments.

Shareholders Will Not Have the Protections Associated With Ownership of Shares in an Investment Company Registered Under the Investment Company Act of 1940.

The Fund is not registered as an investment company under the Investment Company Act of 1940, and is not required to register under such Act. Consequently, Shareholders do not have the regulatory protections provided to the investors in registered and regulated investment companies.

Trading on Commodity Exchanges Outside the United States is Not Subject to U.S. Regulation.

If speculative position limits with respect to a futures contract underlying the Index Commodities has been reached, a portion of the Fund’s trades may take place on markets or exchanges outside the United States. Trading on commodity exchanges outside the United States is not regulated by any United States governmental agency and may involve certain risks not applicable to trading on United States exchanges, including different or diminished investor protections. In trading contracts denominated in currencies other than U.S. dollars, Shares are subject to the risk of adverse exchange-rate movements between the dollar and the functional currencies of such contracts. Investors could incur substantial losses from trading on foreign exchanges which such Investors would not have otherwise been subject had the Fund’s trading been limited to U.S. markets.

Various Actual and Potential Conflicts of Interest May Be Detrimental to Shareholders.

The Fund is subject to actual and potential conflicts of interest involving the Managing Owner, various commodity futures brokers and Authorized Participants. The Managing Owner and its principals, all of whom are engaged in other investment activities, are not required to devote substantially all of their time to the business of the Fund, which also presents the potential for numerous conflicts of interest with the Fund. As a result of these and other relationships, parties involved with the Fund have a financial incentive to act in a manner other than in the best interests of the Fund and the Shareholders. The Managing Owner has not established any formal procedure to resolve conflicts of interest. Consequently, investors are dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the Managing Owner attempts to monitor these conflicts, it is extremely difficult, if not impossible, for the Managing Owner to ensure that these conflicts do not, in fact, result in adverse consequences to the Shareholders.

The Fund may be subject to certain conflicts with respect to the Commodity Broker, including, but not limited to, conflicts that result from receiving greater amounts of compensation from other clients, or purchasing opposite or competing positions on behalf of third party accounts traded through the Commodity Broker.

Tax Related Risks

Shareholders Will Be Subject to Taxation on Their Allocable Share of the Fund’s Taxable Income, Whether or Not They Receive Cash Distributions.

Shareholders will be subject to U.S. federal income taxation and, in some cases, state, local, or foreign income taxation on their allocable share of the Fund’s taxable income, whether or not they receive cash distributions from the Fund. Shareholders may not receive cash distributions equal to their share of the Fund’s taxable income or even the tax liability that results from such income.

Items of Income, Gain, Loss and Deduction With Respect to Shares Could Be Reallocated if the IRS Does Not Accept the Assumptions or Conventions Used by the Fund in Allocating Such Items.

U.S. federal income tax rules applicable to partnerships are complex and often difficult to apply to publicly traded partnerships. The Fund will apply certain assumptions and conventions in an attempt to comply with applicable rules and to report items of income, gain, loss and deduction to the Fund’s Shareholders in a manner that reflects the Shareholders’ beneficial interest in such tax items, but these assumptions and conventions may not be in compliance with all aspects of the applicable tax requirements. It is possible that the IRS will successfully assert that the conventions and assumptions used by the Fund do not satisfy the technical requirements of the Code and/or Treasury Regulations and could require that items of income, gain, loss and deduction be adjusted or reallocated in a manner that adversely affects one or more Shareholders.

The Current Treatment of Long Term Capital Gains Under Current U.S. Federal Income Tax Law May Be Adversely Affected, Changed or Repealed in the Future.

Under current law, long term capital gains are taxed to non-corporate investors at reduced U.S. federal income tax rates. This tax treatment may be adversely affected, changed or repealed by future changes in, or the expiration of, tax laws at any time.

PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISERS AND COUNSEL WITH RESPECT TO THE POSSIBLE TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN THE SHARES; SUCH TAX CONSEQUENCES MAY DIFFER WITH RESPECT TO DIFFERENT INVESTORS.

Other Risks

Failure of Futures Commission Merchants or Commodity Brokers to Segregate Assets May Increase Losses; Despite Segregation of Assets, The Fund Remains at Risk of Significant Losses Because The Fund May Only Receive a Pro-Rata Share of the Assets, or No Assets at All.

The CEAct requires a clearing broker to segregate all funds received from customers from such broker’s proprietary assets. If the Commodity Broker fails to do so, the assets of the Fund might not be fully protected in the event of the Commodity Broker’s bankruptcy. Furthermore, in the event of the Commodity Broker’s bankruptcy, the Fund could be limited to recovering either a pro rata share of all available funds segregated on behalf of the Commodity Broker’s combined customer accounts or the Fund may not recover any assets at all, even though certain property specifically traceable to the Fund was held by the Commodity Broker. The Commodity Broker may, from time-to-time, have been the subject of certain regulatory and private causes of action.

In the event of a bankruptcy or insolvency of any exchange or a clearing house, the Fund could experience a loss of the funds deposited through its Commodity Broker as margin with the exchange or clearing house, a loss of any unrealized profits on its open positions on the exchange, and the loss of profits on its closed positions on the exchange.

The Effect of Market Disruptions and Government Intervention Are Unpredictable and May Have an Adverse Effect on the Value of Your Shares.

The global financial markets have in the past few years gone through pervasive and fundamental disruptions that have led to extensive and unprecedented governmental intervention. Such intervention has in certain cases been implemented on an “emergency” basis, suddenly and substantially eliminating market participants’ ability to continue to implement certain strategies or manage the risk of their outstanding positions. In addition—as one would expect given the complexities of the financial markets and the limited time frame within which governments have felt compelled to take action—these interventions have typically been unclear in scope and application, resulting in confusion and uncertainty which in itself has been materially detrimental to the efficient functioning of the markets as well as previously successful investment strategies.

The Fund may incur major losses in the event of disrupted markets and other extraordinary events in which historical pricing relationships become materially distorted. The risk of loss from pricing distortions is compounded by the fact that in disrupted markets many positions become illiquid, making it difficult or impossible to close out positions against which the markets are moving. The financing available to market participants from their banks, dealers and other counterparties is typically reduced in disrupted markets. Such a reduction may result in substantial losses to the affected market participants. Market disruptions may from time to time cause dramatic losses, and such events can result in otherwise historically low-risk strategies performing with unprecedented volatility and risk.

Regulatory Changes or Actions, Including the Implementation of the Dodd-Frank Act, May Alter the Operations and Profitability of the Fund.

The regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. Considerable regulatory attention has been focused on non-traditional investment pools that are publicly distributed in the United States. The Dodd-Frank Act seeks to regulate markets, market participants and financial instruments that previously have been unregulated and substantially alters the regulation of many other markets, market participants and financial instruments. Because many provisions of the Dodd-Frank Act require rulemaking by the applicable regulators before becoming fully effective and the Dodd-Frank Act mandates multiple agency reports and studies (which could result in additional legislative or regulatory action), it is difficult to predict the impact of the Dodd-Frank Act on the Fund, the Managing Owner, and the markets in which the Fund may invest, the Net Asset Value of the Fund or the market price of the Shares. The Dodd-Frank Act could result in the Fund’s investment strategy becoming non-viable or non-economic to implement. Therefore, the Dodd-Frank Act and regulations adopted pursuant to the Dodd-Frank Act could have a material adverse impact on the profit potential of the Fund and in turn the value of your Shares.

Lack of Independent Advisers Representing Investors.

The Managing Owner has consulted with counsel, accountants and other advisers regarding the formation and operation of the Fund. No counsel has been appointed to represent you in connection with the offering of the Shares. Accordingly, you should consult your own legal, tax and financial advisers regarding the desirability of an investment in the Shares.

Table of Contents

Possibility of Termination of the Fund May Adversely Affect Your Portfolio.

The Managing Owner may withdraw from the Fund upon 120 days’ notice, which would cause the Fund to terminate unless a substitute managing owner was obtained. Owners of 50% of the Shares have the power to terminate the Fund. If it is so exercised, investors who may wish to continue to invest in a vehicle that tracks the Fund’s Index will have to find another vehicle, and may not be able to find another vehicle that offers the same features as the Fund. Such detrimental developments could cause you to liquidate your investments and upset the overall maturity and timing of your investment portfolio. If the registrations with the CFTC or memberships in the NFA of the Managing Owner or the Commodity Broker were revoked or suspended, such entity would no longer be able to provide services to the Fund.

Shareholders Do Not Have the Rights Enjoyed by Investors in Certain Other Vehicles.

As interests in separate series of a Delaware statutory trust, the Shares have none of the statutory rights normally associated with the ownership of shares of a corporation (including, for example, the right to bring “oppression” or “derivative” actions). In addition, the Shares have limited voting and distribution rights (for example, Shareholders do not have the right to elect directors and the Fund is not required to pay regular distributions, although the Fund may pay distributions at the discretion of the Managing Owner).

An Investment in the Shares May Be Adversely Affected by Competition From Other Methods of Investing in Commodities.

The Fund is a relatively new type of investment vehicle. The Fund competes with other financial vehicles, including other commodity pools, hedge funds, traditional debt and equity securities issued by companies in the commodities industry, other securities backed by or linked to such commodities, and direct investments in the underlying commodities or commodity futures contracts. Market and financial conditions, and other conditions beyond the Managing Owner’s control, may make it more attractive to invest in other financial vehicles or to invest in such commodities directly, which could limit the market for the Shares and reduce the liquidity of the Shares.

Competing Claims Over Ownership of Intellectual Property Rights Related to the Fund Could Adversely Affect the Fund and an Investment in the Shares.

While the Managing Owner believes that all intellectual property rights needed to operate the Fund are either owned by or licensed to the Managing Owner or have been obtained, third parties may allege or assert ownership of intellectual property rights which may be related to the design, structure and operations of the Fund. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the negotiation, litigation or settlement of such claims, or the ultimate disposition of such claims in a court of law if a suit is brought, may adversely affect the Fund and an investment in the Shares, for example, resulting in expenses or damages or the termination of the Fund.

The Value of the Shares Will be Adversely Affected if the Fund is Required to Indemnify the Trustee or the Managing Owner.

Under the Trust Agreement, the Trustee and the Managing Owner have the right to be indemnified for any liability or expense either incurs without negligence or misconduct. That means the Managing Owner may require the assets of the Fund to be sold in order to cover losses or liability suffered by it or by the Trustee. Any sale of that kind would reduce the net asset value of the Fund and, consequently, the value of the Shares.

The Net Asset Value Calculation of the Fund May Be Overstated or Understated Due to the Valuation Method Employed When a Settlement Price is not Available on the Date of Net Asset Value Calculation.

Calculating the net asset value of the Fund includes, in part, any unrealized profits or losses on open commodity futures contracts. Under normal circumstances, the net asset value of the Fund reflects the settlement price of open commodity futures contracts on the date when the net asset value is being calculated. However, if a commodity futures contract traded on an exchange (both U.S. and, to the extent it becomes applicable, non-U.S. exchanges) could not be liquidated on such day (due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise), the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. In such a situation, there is a risk that the calculation of the net asset value of the Fund on such day will not accurately reflect the realizable market value of such commodity futures contract. For example, daily limits are generally triggered in the event of a significant change in market price of a commodity futures contract. Therefore, as a result of the daily limit, the current settlement price is unavailable. Because the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards, there is a risk that the resulting calculation of the net asset value of the Fund could be under or overstated, perhaps to a significant degree.

Although the Shares are Limited Liability Investments, Certain Circumstances such as Bankruptcy of the Fund or Indemnification of the Fund by the Shareholders will Increase the Shareholders’ Liability.

The Shares are limited liability investments; investors may not lose more than the amount that they invest plus any profits recognized on their investment. However, Shareholders could be required, as a matter of bankruptcy law, to return to the estate of the Fund any distribution they received at a time when the Fund was in fact insolvent or in violation of its Trust Agreement. In addition, although the Managing Owner is not aware of this provision ever having been invoked in the case of any public futures fund, Shareholders agree in the Trust Agreement that they will indemnify the Fund for any harm suffered by it as a result of:

An Insolvency Resulting From Another Series in the Trust or the Trust Itself May Have a Material Adverse Effect On the Fund.

The Fund is a series or a part of a Delaware statutory trust. Pursuant to Delaware law, the organization of the Trust provides that the assets and liabilities of the Fund are separate from the assets and liabilities of all other series of the Trust, as well as the larger Trust itself. Though such organization may, under state law, protect the assets of the Fund in an insolvency action brought by the creditors of another series of the Trust, this may be insufficient to protect the assets of the Fund from such creditors in an insolvency action in Federal court, or in a court in a foreign jurisdiction. Accordingly, an insolvency resulting from another series in the Trust or the Trust itself may have a material adverse effect on the Fund. The material risks associated with the other series have not been included in this Report.

None.

The Fund does not own or use physical properties in the conduct of its business. Its assets consist of futures contracts, cash, United States Treasury Obligations and may consist of other high credit quality short-term fixed income securities. The Managing Owner’s headquarters are located at 60 Wall Street, New York, New York 10005.

Overview/Introduction

Prior to the close of business on December 31, 2011, the Fund invested substantially all of its assets in the DB Energy Master Fund (the “Master Fund”), a series of the DB Multi-Sector Commodity Trust (the “Master Trust”). After the determination of the net asset value of the Master Fund on December 31, 2011, the Master Fund transferred and distributed all of its assets and liabilities to the Fund and terminated. Effective January 1, 2012, the reorganized Fund has performed all of the necessary functions in order to continue normal Fund operations. The collapse of the master-feeder structure had no effect on the operations or processes of the Fund. All reference to historical results of the Fund include results of the Master Fund where the context requires.

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Energy Index Excess Return™ (the “DBIQ-OY Energy ER™”, or the “Index”), over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the energy sector. The commodities comprising the Index are light sweet crude oil, heating oil, brent crude oil, RBOB gasoline and natural gas (each an “Index Commodity”, and collectively, the “Index Commodities”). The Shares are designed for investors who want a cost-effective and convenient way to invest in a group of commodity futures on U.S. and non-U.S. markets.

As of the date of this Report, each of Deutsche Bank Securities Inc., Merrill Lynch Professional Clearing Corp., Newedge USA LLC, Virtu Financial Capital Markets LLC, Citigroup Global Markets Inc., J.P. Morgan Securities Inc., Credit Suisse Securities (USA) LLC, Virtu Financial BD LLC, Knight Capital Americas LLC, Timber Hill LLC, Morgan Stanley & Co. LLC, Jefferies LLC, Nomura Securities International Inc., RBC Capital Markets, LLC, UBS Securities LLC, Cantor Fitzgerald & Co., BNP Paribas Securities Corp., Goldman, Sachs & Co. and Goldman Sachs Execution & Clearing, L.P. has executed a Participant Agreement and are the only Authorized Participants.

The Fund pursues its investment objective by investing in a portfolio of exchange traded futures contracts that expire in a specific month and trade on a specific exchange (the “Index Contracts”) in the Index Commodities comprising the Index. The Index Commodities are light sweet crude oil, heating oil, brent crude oil, RBOB gasoline and natural gas. The Index is composed of notional amounts of each of the Index Commodities. The Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Fund’s Commodity Broker as margin.

The CFTC and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities included in the Index. As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to any Index Commodity by investing in a specific Index Contract, the Fund may invest in a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with such Index Commodity. Please see http://www.dbxus.com with respect to the most recently available weighted composition of the Fund and the composition of the Index on the Base Date.

Under the Fourth Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”), Wilmington Trust Company, the Trustee of the Trust, has delegated to the Managing Owner the exclusive management and control of all aspects of the business of the Trust and the Fund. The Trustee will have no duty or liability to supervise or monitor the performance of the Managing Owner, nor will the Trustee have any liability for the acts or omissions of the Managing Owner.

The Index Sponsor obtains information for inclusion in, or for use in the calculation of, the Index from sources the Index Sponsor considers reliable. None of the Index Sponsor, the Managing Owner, the Trust, the Fund or any of their respective affiliates accepts responsibility for or guarantees the accuracy and/or completeness of the Index or any data included in the Index.

The Shares are intended to provide investment results that generally correspond to the changes, positive or negative, in the levels of the Index over time. The value of the Shares is expected to fluctuate in relation to changes in the value of the Fund’s portfolio. The market price of the Shares may not be identical to the net asset value per Share, but these two valuations are expected to be very close.

Margin Calls

Like other futures and derivatives traders, the Fund will be subject to margin calls from time-to-time. The term “margin” has a different meaning in the context of futures contracts and other derivatives than it does in the context of securities. In particular, “margin” on a futures position does not constitute a borrowing of money or the collateralization of a loan. The Fund does not borrow money.

To establish a position in an exchange-traded futures contract, the Fund makes a deposit of “initial margin.” The amount of initial margin required to be deposited in order to establish a position in an exchange-traded futures contract varies from instrument to instrument depending, generally, on the historical volatility of the futures contract in question. Determination of the amount of the required initial margin deposit in respect of a particular contract is made by the exchange on which the contract is listed. To establish a long position in an over-the-counter instrument, the counterparty may require an analogous deposit of collateral, depending upon the anticipated volatility of the instrument and the creditworthiness of the person seeking to establish the position. The deposit of initial margin provides assurance to futures commission merchants and clearing brokers involved in the settlement process that sufficient resources are likely to be on deposit to enable a client’s position to be closed by recourse to the initial margin deposit should the client fail to meet a demand for variation margin, even if changes in the value of the contract in question, which are marked to market from day to day, continue to reflect the contract’s historical volatility. Collateral deposited in support of an over-the-counter instrument serves a similar purpose.

Once a position has been established on a futures exchange, “variation margin” generally is credited or assessed at least daily to reflect changes in the value of the position, except in certain instances where midday variation margin calls are made. In contrast to “initial margin,” “variation margin” represents a system of marking to market the futures contract’s value. Thus, traders in exchange-traded futures contracts are assessed daily in an amount equal to that day’s accumulated losses in respect of any open position (or are credited daily with accumulated gains in respect of such position). Collateral may move between the parties to an over-the-counter instrument in a similar manner as gains or losses accumulate in the instrument. As with initial margin, variation margin serves to secure the obligations of the investor under the contract and to protect those involved in the settlement process against the possibility that a client will have insufficient resources to meet its contractual obligations. Collateral deposited in support of an over-the-counter instrument serves a similar purpose. Like initial margin (or an equivalent deposit of collateral), variation margin (or an equivalent deposit of collateral) does not constitute a borrowing of money, is not considered to be part of the contract purchase price and is returned upon the contract’s termination unless it is used to cover a loss in the contract position. United States Treasury Obligations are used routinely to collateralize OTC derivative positions, and are deposited routinely as margin to collateralize futures positions. The Fund may liquidate United States Treasury Obligations to meet an initial or variation margin requirement.

Performance Summary

This report covers the three months ended December 31, 2013, 2012 and 2011 (herein referred to as the “Three Months Ended December 31, 2013”, the “Three Months Ended December 31, 2012” and the “Three Months Ended December 31, 2011,” respectively), the years ended December 31, 2013, 2012 and 2011 (herein referred to as the “Year Ended December 31, 2013”, the “Year Ended December 31, 2012” and the “Year Ended December 31, 2011,” respectively). The Fund commenced trading on the American Stock Exchange (which became the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007, and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

Performance of the Fund and the exchange traded Shares are detailed below in “Results of Operations”. Past performance of the Fund and the exchange traded Shares are not necessarily indicative of future performance.

The Index is intended to reflect the change in market value of the Index Commodities. In turn, the Index is intended to reflect the energy sector. The DBIQ Optimum Yield Energy Index Total Return™ (the “DBIQ-OY Energy TR™”) consists of the Index plus 3 month United States Treasury Obligations returns. Past Index results are not necessarily indicative of future changes, positive or negative, in the Index closing levels.

The section “Summary of the DBIQ-OY Energy TR™ and Underlying Index Commodity Returns for the Three Months Ended December 31, 2013, 2012 and 2011 and the Years Ended December 31, 2013, 2012 and 2011” below provides an overview of the changes in the closing levels of the DBIQ-OY Energy TR™ by disclosing the change in market value of each underlying component Index Commodity through a “surrogate” (and analogous) index plus 3 month United States Treasury Obligations returns. Please note also that the Fund’s objective is to track the Index (not the DBIQ-OY Energy TR™) and the Fund does not attempt to outperform or underperform the Index. The Index employs the optimum yield roll method with the objective of mitigating the negative effects of contango, the condition in which distant delivery prices for futures exceed spot prices, and maximizing the positive effects of backwardation, a condition opposite of contango.

Summary of the DBIQ-OY Energy TR™ and Underlying Index Commodity Returns for the Three Months Ended December 31, 2013, 2012 and 2011 and the Years Ended December 31, 2013, 2012 and 2011.

If the Fund’s interest income from its holdings of fixed income securities were to exceed the Fund’s fees and expenses, the aggregate return on an investment in the Fund is expected to outperform the Index and underperform the DBIQ-OY Energy TR™. The only difference between (i) the Index and (ii) the DBIQ-OY Energy TR™ is that the Index does not include interest income from a hypothetical basket of fixed income securities while the DBIQ-OY Energy TR™ does include such a component. Thus, the difference between the Index and the DBIQ-OY Energy TR ™is attributable entirely to the hypothetical interest income from this hypothetical basket of fixed income securities. If the Fund’s interest income from its holdings of fixed income securities exceeds the Fund’s fees and expenses, then the amount of such excess is expected to be distributed periodically. The market price of the Shares is expected to closely track the Index. The aggregate return on an investment in the Fund over any period is the sum of the capital appreciation or depreciation of the Shares over the period, plus the amount of any distributions during the period. Consequently, the Fund’s aggregate return is expected to outperform the Index by the amount of the excess, if any, of its interest income over its fees and expenses but, as a result of the Fund’s fees and expenses, the aggregate return on the Fund is expected to underperform the DBIQ-OY Energy TR™. If the Fund’s fees and expenses were to exceed the Fund’s interest income from its holdings of fixed income securities, the aggregate return on an investment in the Fund is expected to underperform the Index.

Net Asset Value

Net asset value means the total assets of the Fund, including, but not limited to, all futures, cash and investments less total liabilities of the Fund, each determined on the basis of U.S. generally accepted accounting principles, consistently applied under the accrual method of accounting. In particular, net asset value includes any unrealized appreciation or depreciation on open commodity futures contracts, and any other credit or debit accruing to the Fund but unpaid or not received by the Fund. All open commodity futures contracts will be calculated at their then current market value, which will be based upon the settlement price for that particular commodity futures contract traded on the applicable exchange on the date with respect to which net asset value is being determined; provided, that if a commodity futures contract could not be liquidated on such day, due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise, the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. The Managing Owner may in its discretion (and under circumstances, including, but not limited to, periods during which a settlement price of a futures contract is not available due to exchange limit orders or force majeure type events such as systems failure, natural or man-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance) value any asset of the Fund pursuant to such other principles as the Managing Owner deems fair and equitable so long as such principles are consistent with normal industry standards. Interest earned on the Fund’s brokerage account is accrued monthly. The amount of any distribution is a liability of the Fund from the day when the distribution is declared until it is paid.

Net asset value per share is the net asset value of the Fund divided by the number of outstanding shares.

Critical Accounting Policies

The Fund’s critical accounting policies are as follows:

Preparation of the financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires the application of appropriate accounting rules and guidance, as well as the use of estimates, and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expense and related disclosure of contingent assets and liabilities during the reporting period of the financial statements and accompanying notes. The Fund’s application of these policies involves judgments and actual results may differ from the estimates used.

The Fund holds a significant portion of its assets in futures contracts and United States Treasury Obligations, both of which are recorded on a trade date basis and at fair value in the financial statements, with changes in fair value reported in the statement of income and expenses.

The use of fair value to measure financial instruments, with related unrealized gains or losses recognized in earnings in each period is fundamental to the Fund’s financial statements. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

In determining fair value of United States Treasury Obligations and commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. Financial Accounting Standards Board (FASB) Accounting Standards Codification for fair value measurement and disclosure guidance requires a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The objective of a fair value measurement is to determine the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The hierarchy gives the highest priority to unadjusted quoted prices for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. See Note 4(c) within the financial statements in Item 8 for further information.

When market closing prices are not available, the Managing Owner may value an asset of the Fund pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards.

Realized gains (losses) and changes in unrealized gain (loss) on open positions are determined on a specific identification basis and recognized in the statement of income and expenses in the period in which the contract is closed or the changes occur, respectively.

Interest income on United States Treasury Obligations is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the United States Treasury Obligations.

Market Risk

Trading in futures contracts involves the Fund entering into contractual commitments to purchase a particular commodity at a specified date and price. The market risk associated with the Fund’s commitments to purchase commodities is limited to the gross or face amount of the contracts held.

The Fund’s exposure to market risk is also influenced by a number of factors including the volatility of interest rates and foreign currency exchange rates, the liquidity of the markets in which the contracts are traded and the relationships among the contracts held. The inherent uncertainty of the Fund’s trading as well as the development of drastic market occurrences could ultimately lead to a loss of all or substantially all of the investors’ capital.

Credit Risk

When the Fund enters into futures contracts, the Fund is exposed to credit risk that the counterparty to the contract will not meet its obligations. The counterparty for futures contracts traded on United States and on most foreign futures exchanges is the clearing house associated with the particular exchange. In general, clearing houses are backed by their corporate members who may be required to share in the financial burden resulting from the nonperformance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearing house is not backed by the clearing members (i.e., some foreign exchanges), it may be backed by a consortium of banks or other financial institutions. There can be no assurance that any counterparty, clearing member or clearinghouse will meet its obligations to the Fund.

The Commodity Broker, when acting as the Fund’s futures commission merchant in accepting orders for the purchase or sale of domestic futures contracts, is required by CFTC regulations to separately account for and segregate as belonging to the Fund all assets of the Fund relating to domestic futures trading and the Commodity Broker is not allowed to commingle such assets with other assets of the Commodity Broker. In addition, CFTC regulations also require the Commodity Broker to hold in a secure account assets of the Fund related to foreign futures trading. Also, see Item 1A.—Risk Factors—“Failure of Futures Commission Merchants or Commodity Brokers to Segregate Assets May Increase Losses; Despite Segregation of Assets, The Fund Remains at Risk of Significant Losses Because The Fund May Only Receive a Pro-Rata Share of the Assets, or No Assets at All.” In addition, CFTC regulations also require the Commodity Broker to hold in a secure account assets of the Fund related to foreign futures trading.

Liquidity

The Fund’s entire source of capital is derived from the Fund’s offering of Shares to Authorized Participants. The Fund in turn allocates its net assets to commodities trading. A significant portion of the net asset value is held in United States Treasury Obligations and cash, which is used as margin for the Fund’s trading in commodities. The percentage that United States Treasury Obligations bear to the total net assets will vary from period to period as the market values of the Fund’s commodity interests change. The balance of the net assets is held in the Fund’s commodity trading account. Interest earned on the Fund’s interest-bearing funds is paid to the Fund.

The Fund’s commodity contracts may be subject to periods of illiquidity because of market conditions, regulatory considerations or for other reasons. For example, commodity exchanges generally have the ability to limit fluctuations in certain commodity futures contract prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a particular futures contract for a particular commodity has increased or decreased by an amount equal to the daily limit, positions in the commodity futures contract can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Commodity futures prices have occasionally moved the daily limit for several consecutive days with little or no trading. Such market conditions could prevent the Fund from promptly liquidating its commodity futures positions.

Because the Fund trades futures contracts, its capital is at risk due to changes in the value of futures contracts (market risk) or the inability of counterparties (including the Commodity Broker and/or exchange clearinghouses) to perform under the terms of the contracts (credit risk).

On any business day, an Authorized Participant may place an order with the Transfer Agent to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m., Eastern Time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. The day on which a redemption order is settled is the redemption order settlement date. As provided below, the redemption order settlement date may occur up to 3 business days after the redemption order date. Redemption orders are irrevocable. The redemption procedures allow only Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from the Fund. Instead, individual Shareholders may only redeem Shares in integral multiples of 200,000 and only through an Authorized Participant.

Table of Contents

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, by placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the applicable Fund not later than the redemption order settlement date as of 2:45 p.m., Eastern time, on the business day immediately following the redemption order date. Upon submission of a redemption order, the Authorized Participant may request the Managing Owner to agree to a redemption order settlement date up to 3 business days after the redemption order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participant’s DTC account is charged the non-refundable transaction fee due for the redemption order.

Redemption orders may be placed either (i) through the Continuous Net Settlement (“CNS”) clearing processes of the National Securities Clearing Corporation (the “NSCC”) or (ii) if outside the CNS Clearing Process, only through the facilities of The Depository Trust Company (“DTC” or the “Depository”) (the “DTC Process”), or a successor depository, and only in exchange for cash. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participant’s DTC account is charged the non-refundable transaction fee due for the redemption order and such fee is not borne by the Fund.

Cash Flows

The primary cash flow activity of the Fund is to raise capital from Authorized Participants through the issuance of Shares. This cash is used to invest in United States Treasury Obligations and to meet margin requirements as a result of the positions taken in futures contracts to match the fluctuations of the Index the Fund is tracking.

Operating Activities

Net cash flow provided by and (used for) operating activities was $(140.6) million, $17.6 million and $8.5 million for the Years Ended December 31, 2013, 2012 and 2011, respectively. This amount primarily includes net purchases and sales of United States Treasury Obligations which are held at fair value on the statement of financial condition.

During the Year Ended December 31, 2013, $958.9 million was paid to purchase United States Treasury Obligations and $820.9 million was received from sales and maturing contracts. During the Year Ended December 31, 2012, $592.5 million was paid to purchase United States Treasury Obligations and $624.6 million was received from sales and maturing contracts. During the Year Ended December 31, 2011, $722.5 million was paid to purchase United States Treasury Obligations and $706.6 million was received from sales and maturing contracts. Unrealized appreciation on United States Treasury Obligations and futures increased by $9.3 million, increased by $11.4 million and decreased by $20.5 million during the Years Ended December 31, 2013, 2012 and 2011, respectively.

Financing Activities

The Fund’s net cash flow provided by and (used for) financing activities was $121.7 million, $(6.1) million and $(16.3) million during the Years Ended December 31, 2013, 2012 and 2011, respectively. This included $228.9 million, $112.2 million and $113.8 million from the sale of Shares to Authorized Participants during the Years Ended December 31, 2013, 2012 and 2011, respectively.

FOR THE THREE MONTHS ENDED DECEMBER 31, 2013, 2012 AND 2011 AND FOR THE YEARS ENDED DECEMBER 31, 2013, 2012 AND 2011

The Fund was launched on January 3, 2007 at $25.00 per Share. The Shares traded on the NYSE Alternext from January 5, 2007 to November 25, 2008 and have been trading on the NYSE Arca since November 25, 2008.

The Fund seeks to track changes in the closing levels of the DBIQ Optimum Yield Energy Index Excess Return™ (the “DBIQ-OY Energy ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The following graphs illustrate changes in (i) the price of the Shares (as reflected by the graph “DBE”), (ii) the Fund’s NAV (as reflected by the graph “DBENV”), and (iii) the closing levels of the Index (as reflected by the graph “DBENIX”). Whenever the interest income earned by the Fund exceeds Fund expenses, the price of the Shares generally has exceeded the levels of the Index primarily because the Share price reflects interest income from the Fund’s collateral holdings whereas the Index does not consider such interest income. There can be no assurances that the price of the Shares will exceed the Index levels.

The Index is a set of rules applied to a body of data and does not represent the results of actual investment or trading. The Index is frictionless, in that it does not take into account fees or expenses associated with investing in the Fund. Also, because it does not represent actual futures positions, the Index is not subject to, and does not take into account the impact of, speculative position limits or certain other similar limitations on the ability of the Fund to trade the Index Commodities. The “TR” version of the Index includes an assumed amount of interest income based on prevailing rates that is adjusted from time to time. The Fund, by contrast, invests actual money and trades actual futures contracts. As a result, the performance of the Fund involves friction, in that fees and expenses impose a drag on performance. The Fund may be subject to speculative position limits and certain other limitations on its ability to trade the Index Commodities, which may compel the Fund to trade futures or other instruments that are not Index Commodities as proxies for the Index Commodities. The interest rate actually earned by the Fund over any period may differ from the assumed amount of interest income factored into the “TR” version of the Index over the same period. All of these factors can contribute to discrepancies between changes in net asset value per Share and changes in the level of the Index over any period of time. Fees and expenses always will tend to cause changes in the net asset value per Share to underperform changes in the value of the Index over any given period, all other things being equal. Actual interest income could be higher or lower than the assumed interest income factored into the “TR” version of the Index, and therefore could cause changes in the net asset value per Share to outperform or underperform changes in the value of the “TR” version of the Index over any given period, all other things being equal. Similarly, trading futures or other instruments that are not Index Commodities as proxies for the Index Commodities could cause changes in the net asset value per Share to outperform or underperform changes in the value of the Index over any given period, all other things being equal.

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Energy Index Excess Return™ (the “DBIQ-OY Energy ER™”, or the “Index”), over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the energy sector. The commodities comprising the Index are light sweet crude oil, heating oil, brent crude oil, RBOB gasoline and natural gas (each an “Index Commodity”, and collectively, the “Index Commodities”). The Shares are designed for investors who want a cost-effective and convenient way to invest in a group of commodity futures on U.S. and non-U.S. markets.

DBIQ Optimum Yield Energy Index Excess Return™ is an index and does not reflect (i) actual trading and (ii) any fees or expenses.

WHILE THE FUND’S OBJECTIVE IS NOT TO GENERATE PROFIT THROUGH ACTIVE PORTFOLIO MANAGEMENT, BUT IS TO TRACK THE INDEX, BECAUSE THE INDEX WAS ESTABLISHED IN JULY 2006 (RENAMED IN OCTOBER 2010), CERTAIN INFORMATION RELATING TO THE INDEX CLOSING LEVELS MAY BE CONSIDERED TO BE “HYPOTHETICAL.” HYPOTHETICAL INFORMATION MAY HAVE CERTAIN INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW.

WITH RESPECT TO INDEX DATA, NO REPRESENTATION IS BEING MADE THAT THE INDEX WILL OR IS LIKELY TO ACHIEVE ANNUAL OR CUMULATIVE CLOSING LEVELS CONSISTENT WITH OR SIMILAR TO THOSE SET FORTH HEREIN. SIMILARLY, NO REPRESENTATION IS BEING MADE THAT THE FUND WILL GENERATE PROFITS OR LOSSES SIMILAR TO THE FUND’S PAST PERFORMANCE OR THE HISTORICAL ANNUAL OR CUMULATIVE CHANGES IN THE INDEX CLOSING LEVELS. IN FACT, THERE ARE FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL RESULTS AND THE ACTUAL RESULTS SUBSEQUENTLY ACHIEVED BY INVESTMENT METHODOLOGIES, WHETHER ACTIVE OR PASSIVE.

WITH RESPECT TO INDEX DATA, ONE OF THE LIMITATIONS OF HYPOTHETICAL INFORMATION IS THAT IT IS GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT.

Off-Balance Sheet Arrangements and Contractual Obligations

In the normal course of its business, the Fund is a party to financial instruments with off-balance sheet risk. The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in a future obligation or loss. The financial instruments used by the Fund are commodity futures, whose values are based upon an underlying asset and generally represent future commitments which have a reasonable possibility to be settled in cash or through physical delivery. The financial instruments are traded on an exchange and are standardized contracts.

The Fund has not utilized, nor does it expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and has no loan guarantee arrangements or off-balance sheet arrangements of any kind, other than agreements entered into in the normal course of business noted above, which may include indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund. While the Fund’s exposure under such indemnification provisions cannot be estimated, these general business indemnifications are not expected to have a material impact on the Fund’s financial position.

The Fund’s contractual obligations are with the Managing Owner and the Commodity Broker. Management Fee payments made to the Managing Owner are calculated as a fixed percentage of the Fund’s net asset value. Commission payments to the Commodity Broker are on a contract-by-contract, or round-turn, basis. As such, the Managing Owner cannot anticipate the amount of payments that will be required under these arrangements for future periods as net asset values are not known until a future date. These agreements are effective for one year terms, renewable automatically for additional one year terms unless terminated. Additionally, these agreements may be terminated by either party for various reasons.

INTRODUCTION

The Fund is designed to replicate positions in a commodity index. The market sensitive instruments held by it are subject to the risk of trading loss. Unlike an operating company, the risk of market sensitive instruments is integral, not incidental, to the Fund’s main line of business.

Market movements can produce frequent changes in the fair market value of the Fund’s open positions and, consequently, in its earnings and cash flow. The Fund’s market risk is primarily influenced by changes in the price of commodities.

Standard of Materiality

Materiality as used in this section, “Quantitative and Qualitative Disclosures About Market Risk,” is based on an assessment of reasonably possible market movements and the potential losses caused by such movements, taking into account the effects of margin, and any other multiplier features, as applicable, of the Fund’s market sensitive instruments.

QUANTIFYING THE FUND’S TRADING VALUE AT RISK

Quantitative Forward-Looking Statements

The following quantitative disclosures regarding the Fund’s market risk exposures contain “forward-looking statements” within the meaning of the safe harbor from civil liability provided for such statements by the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934). All quantitative disclosures in this section are deemed to be forward-looking statements for purposes of the safe harbor, except for statements of historical fact (such as the dollar amount of maintenance margin required for market risk sensitive instruments held at the end of the reporting period).

Value at risk, or VaR, is a statistical measure of the value of losses that would not be expected to be exceeded over a given time horizon and at a given probability level arising from movement of underlying risk factors. Loss is measured as a decline in the fair value of the portfolio as a result of changes in any of the material variables by which fair values are determined. VaR is measured over a specified holding period (1 day) and to a specified level of statistical confidence (99th percentile). However, the inherent uncertainty in the markets in which the Fund trades and the recurrence in the markets traded by the Fund of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated VaR or the Fund’s experience to date (i.e., “risk of ruin”). In light of this, as well as the risks and uncertainties intrinsic to all future projections, the inclusion of the quantification included in this section should not be considered to constitute any assurance or representation that the Fund’s losses in any market sector will be limited to VaR or by the Fund’s attempts to manage its market risk.

THE FUND’S TRADING VALUE AT RISK

The Fund calculates VaR using the actual historical market movements of the Fund’s total assets.

The following table indicates the trading VaR associated with the Fund’s total assets as of December 31, 2013.

NON-TRADING RISK

The Fund has non-trading market risk as a result of investing in short-term United States Treasury Obligations. The market risk represented by these investments is expected to be immaterial.

QUALITATIVE DISCLOSURES REGARDING PRIMARY TRADING RISK EXPOSURES

The following qualitative disclosures regarding the Fund’s market risk exposures—except for those disclosures that are statements of historical fact—constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. The Fund’s primary market risk exposures are subject to numerous uncertainties, contingencies and risks. Government interventions, defaults and expropriations, illiquid markets, the emergence of dominant fundamental factors, political upheavals, changes in historical price relationships, an influx of new market participants, increased regulation and many other factors could result in material losses as well as in material changes to the risk exposures of the Fund. There can be no assurance that the Fund’s current market exposure will not change materially. Investors may lose all or substantially all of their investment in the Fund.

The following were the primary trading risk exposures of the Fund as of December 31, 2013 by Index Commodity:

Light Sweet Crude Oil

The price of light sweet crude oil is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for light sweet crude oil. In addition, various other factors can affect the demand for light sweet crude oil, such as weather, political events and labor activity. The supply of light sweet crude oil can be affected by many events, in particular, the meetings of the Organization of Petroleum Exporting Countries. Market expectations about events that will influence either demand or supply can cause prices for light sweet crude oil to fluctuate greatly. A significant amount of the world oil production capacity is controlled by a relatively small number of producers. Any large change in production by one of these producers could have a substantial effect on the price of light sweet crude oil.

Heating Oil

The price of heating oil is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for heating oil. In addition, the seasonal temperatures in countries throughout the world can also heavily influence the demand for heating oil. Heating oil is derived from crude oil and as such, any factors that influence the supply of crude oil may also influence the supply of heating oil.

Brent Crude Oil

The price of Brent crude oil is volatile and is affected by numerous factors. The price of Brent crude oil is influenced by many factors, including, but not limited to, the amount of output by oil producing nations, worldwide supply/stockpiles, weather, various geopolitical factors that cause supply disruptions (e.g., war, terrorism), global demand (particularly from emerging nations), currency fluctuations, and activities of market participants such as hedgers and speculators.

RBOB Gasoline

The price of RBOB Gasoline is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for RBOB Gasoline. In addition, the demand has seasonal variations, which occur during “driving seasons” usually considered the summer months in North America and Europe. RBOB Gasoline is derived from crude oil and as such, any factors that influence the supply of crude oil may also influence the supply of RBOB Gasoline.

Natural Gas

The price of natural gas is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for natural gas. In addition to the seasonal temperatures in countries throughout the world, any fluctuations in temperature may also heavily influence the demand for natural gas.

QUALITATIVE DISCLOSURES REGARDING NON-TRADING RISK EXPOSURE

General

The Fund is unaware of any (i) anticipated known demands, commitments or capital expenditures; (ii) material trends, favorable or unfavorable, in its capital resources; or (iii) trends or uncertainties that will have a material effect on operations.

QUALITATIVE DISCLOSURES REGARDING MEANS OF MANAGING RISK EXPOSURE

Under ordinary circumstances, the Managing Owner’s discretionary power is limited to determining whether the Fund will make a distribution. Under emergency or extraordinary circumstances, the Managing Owner’s discretionary powers increase, but remain circumscribed. These special circumstances, for example, include the unavailability of the Index or certain natural or man-made disasters. The Managing Owner does not apply risk management techniques. The Fund initiates positions only on the “long” side of the market and does not employ “stop-loss” techniques.

Report of Management on Internal Control

over Financial Reporting

Management of DB Commodity Services LLC, as managing owner (the “Managing Owner”) of PowerShares DB Energy Fund (the “Fund”), is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Fund; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Fund’s receipts and expenditures are being made only in accordance with appropriate authorizations of management; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Fund’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, errors or fraud. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We, Martin Kremenstein, Chief Executive Officer, and Michael Gilligan, Chief Financial Officer, of the Managing Owner, assessed the effectiveness of the Fund’s internal control over financial reporting as of December 31, 2013. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (1992). The assessment included an evaluation of the design of the Fund’s internal control over financial reporting and testing of the operational effectiveness of its internal control over financial reporting. Based on our assessment and those criteria, we have concluded that the Fund maintained effective internal control over financial reporting as of December 31, 2013.

The Fund’s independent registered public accounting firm, PricewaterhouseCoopers LLP, has audited the Fund’s internal control over financial reporting as of December 31, 2013, as stated in their report on page 37 of the Fund’s Annual Report on Form 10-K.

The Board of Managers of DB Commodity Services LLC and

The Shareholders of PowerShares DB Energy Fund:

In our opinion, the accompanying statement of financial condition, including the schedule of investments, and the related statements of income and expenses, changes in shareholders’ equity and of cash flows, present fairly, in all material respects, the financial position of PowerShares DB Energy Fund (the “Fund”), a series of the PowerShares DB Multi-Sector Commodity Trust, at December 31, 2013, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Fund maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Fund’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Fund’s internal control over financial reporting based on our integrated audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audit of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A fund’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A fund’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the fund; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the fund are being made only in accordance with authorizations of management of the fund; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the fund’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
