#### Letter from the Chair of the Board & President
Dear Shareholder,

2022 was a challenging year in the financial markets. We continue to work tirelessly to navigate global markets and manage the assets that you have entrusted with us. Following this letter is the PIMCO Energy and Tactical Credit Opportunities Fund's Semiannual Report, which covers the six-month reporting period ended December 31, 2022 (the "reporting period"). On the subsequent pages, you will find details regarding investment results and a discussion of the factors that most affected performance during the reporting period.

For the six-month reporting period ended December 31, 2022

The global economy faced significant headwinds in 2022, including those related to higher inflation, the COVID-19 pandemic, and the Russia-Ukraine conflict. In the U.S., second quarter 2022, prior to the beginning of the reporting period, annualized gross domestic product ("GDP") was -0.6%. The economy then strengthened, as third quarter annualized GDP was +3.2%. The Commerce Department's initial estimate for fourth quarter 2022 annualized GDP — released after the reporting period ended — was 2.9%.

The Federal Reserve Board (the "Fed" or "U.S. central bank") took actions to combat elevated inflation. In March 2022, the Fed raised the federal funds rate 0.25% to a range between 0.25% and 0.50%, its first rate hike since 2018. The U.S. central bank then raised rates at its next six meetings, for a total increase of 4.25% in 2022. At the end of the year, the federal funds rate was in a range between 4.25% and 4.50%.

Economies outside the U.S. also faced several headwinds. In its October 2022 World Economic Outlook Update, the International Monetary Fund (the "IMF") downgraded its expectation for 2022 GDP citing "turbulent challenges" including high inflation, tightening financial conditions, as well as the ongoing Russia-Ukraine conflict and COVID-19 pandemic. For 2022, the IMF included in its projections that GDP would grow 1.6% in the U.S. (from 5.7% in 2021), 3.1% in the eurozone (from 5.2% in 2021), 3.6% in the U.K. (from 7.4% in 2021), and 1.7% in Japan (the same as in 2021).

Several central banks tightened their respective monetary policies in recent years. For example, in December 2021, prior to the beginning of the reporting period, the Bank of England (the "BoE") raised rates for the first time since COVID-19 began. The BoE again raised rates at its next eight meetings, for a total of 3.50% in rate hikes since its first increase. The European Central Bank raised rates four times in 2022, for a total increase of 2.50%. In contrast, the Bank of Japan (the "BoJ") maintained its loose monetary policy for most of 2022. However, in December 2022 the BoJ announced that it would allow its 10-year government bond yield to rise to 0.5% (previously limited to 0.25%). The news sent the 10-year bond yield and Japanese yen higher, as

market participants interpreted the announcement to mean that the BoJ may pivot from its previous monetary stance.

During the reporting period, short- and long-term U.S. Treasury yields moved higher. The yield on the benchmark 10-year U.S. Treasury note was 3.88% on December 31, 2022, versus 2.98% on June 30, 2022. The Bloomberg Global Treasury Index (USD Hedged), which tracks fixed-rate, local currency government debt of investment grade countries, including developed and emerging markets, returned -2.97%. Meanwhile, the Bloomberg Global Aggregate Credit Index (USD Hedged), a widely used index of global investment grade credit bonds, returned -1.59%. In contrast, riskier fixed income asset classes, including high yield corporate bonds and emerging market debt, generated positive returns. The ICE BofAML Developed Markets High Yield Constrained Index (USD Hedged), a widely used index of below-investment-grade bonds, returned 3.82%, whereas emerging market external debt, as represented by the JPMorgan Emerging Markets Bond Index (EMBI) Global (USD Hedged), returned 2.93%. Emerging market local bonds, as represented by the JPMorgan Government Bond Index-Emerging Markets Global Diversified Index (Unhedged), returned 3.33%.

Amid periods of volatility, global equities generally posted mixed results during the reporting period as economic and geopolitical concerns impacted investor sentiment. U.S. equities, as represented by the S&P 500 Index, returned 2.31%. Global equities, as represented by the MSCI World Index, returned 2.97%, while emerging market equities, as measured by the MSCI Emerging Markets Index, returned -2.99%. Meanwhile, Japanese equities, as represented by the Nikkei 225 Index (in Japanese yen), returned -0.06% and European equities, as represented by the MSCI Europe Index (in euro), returned 5.05%.

Commodity prices were volatile and generated mixed returns during the reporting period. Brent crude oil, which was approximately $119.78 a barrel at the start of the reporting period, fell to roughly $82.82 a barrel at the end of December 2022. In contrast, prices of other commodities, such as copper and gold, edged higher during the period.

Finally, there were also periods of volatility in the foreign exchange markets. We believe this was driven by several factors, including economic growth expectations and changing central bank monetary policies, as well as rising inflation, COVID-19 variants, and geopolitical events. The U.S. dollar was mixed against several major currencies. For example, during the reporting period, the U.S. dollar returned -2.11%, +0.78%, and -3.51% versus the euro, the British pound and the Japanese yen, respectively.

Thank you for the assets you have placed with us. We deeply value your trust, and we will continue to work diligently to meet your broad investment needs. For any questions regarding your PIMCO Energy and Tactical Credit Opportunities Fund

#### I mportant Information About the PIMCO Energy and Tactical Credit Opportunities Fund
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in investments linked to the energy sector and in investments linked to the credit sectors.

Investments linked to the energy sector may include investments in equity and debt securities, warrants, rights issues, and restricted securities of energy companies, including, but not limited to, publicly traded corporations; publicly traded partnerships (including master limited partnerships and limited liability companies that are treated as partnerships for U.S. federal income tax purposes ("MLPs")); certain affiliates of MLPs; publicly traded limited liability companies that are treated as corporations for U.S. federal income tax purposes; private partnerships and limited liability companies; royalty trusts; and special purpose entities used to gain access to these types of investments. The Fund may also invest in derivative instruments that provide economic exposure to these types of investments.

MLPs that concentrate in the energy sector are subject to risks associated with the energy sector. MLP units may trade infrequently and in limited volume, and they may be subject to abrupt or erratic price movements. MLP common units and other equity securities issued by MLPs are subject to the risks associated with all equity investments, including the risk that the value of such equity securities will decline due to general market or economic conditions, perceptions regarding MLPs or the energy sector, changes in interest rates, changes in a particular issuer's financial condition, or unfavorable or unanticipated poor performance of a particular issuer. Debt securities issued by MLPs are subject to the risks associated with all debt investments, including interest rate risk, prepayment risk, credit risk, and, as applicable, high yield securities risk and distressed and defaulted securities risk. Many MLPs and other companies in which the Fund may invest operate natural gas, natural gas liquids, crude oil, refined products, coal or other facilities within the energy sector. Investments in MLPs are also generally subject to many of the risks that apply to partnerships. For example, holders of the units of MLPs may have limited control and limited voting rights on matters affecting the partnership. Also, investments in MLPs or other entities that hold a general partner or managing member interest in MLPs can lead to liability in certain circumstances for amounts greater than the amount of investment in such interests. There may be fewer corporate protections afforded investors in an MLP than investors in a corporation. Conflicts of interest may exist among unit holders, subordinated unit holders and the general partner of an MLP, including those arising from incentive distribution payments.

The Fund has a fundamental policy to invest at least 25% of its total assets in the energy industry. As a result, the Fund will be susceptible to adverse economic, environmental or regulatory occurrences affecting that sector. The energy sector is highly regulated. MLPs and other entities operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by federal, state and local governmental agencies. MLPs and other entities operating in the energy sector are subject to many dangers inherent in the production, exploration, management, transportation, processing, and distribution of natural gas, natural gas liquids (including propane), crude oil, refined petroleum and petroleum products and other hydrocarbons. A downturn in the energy sector could have a larger impact on the Fund than on funds that are broadly diversified across many sectors and industries. At times, the performance of securities of companies in the energy sector may lag behind the performance of other sectors or industries or the broader market as a whole.

#### Important Information About the PIMCO Energy and Tactical Credit Opportunities Fund (Cont.)
The Fund may also invest in a wide range of credit sectors, including, without limit, corporate debt, including fixed-, variable-, and floating rate bonds, loans and debt securities issued by U.S. and foreign corporations, including emerging market issuers.

The use of derivatives may subject the Fund to greater volatility than investments in traditional securities. The Fund may use derivative instruments for hedging purposes or as part of an investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk (which may be heightened for highly-customized derivatives), interest rate risk, market risk, credit risk and management risk, as well as risks arising from changes in applicable requirements. They also involve the risk of improper valuation and the risk that changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, rate or index.

Changes in regulation relating to the Fund's use of derivatives and related instruments could potentially limit or impact the Fund's ability to invest in derivatives, limit the Fund's ability to employ certain strategies that use derivatives and/or adversely affect the value or performance of derivatives and the Fund. Certain derivative transactions may have a leveraging effect on the Fund. For example, a small investment in a derivative instrument may have a significant impact on the Fund's exposure to interest rates, currency exchange rates or other investments. As a result, a relatively small price movement in a derivative instrument may cause an immediate and substantial loss or gain. The Fund may engage in such transactions regardless of whether the Fund owns the asset, instrument or components of the index underlying the derivative instrument. The Fund may invest a significant portion of its assets in these types of instruments. If it does, the Fund's investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own.

Strategies involving interest rate derivatives (including swaps that are paired) may attempt to capitalize on differences between short term and long-term interest rates as part of the Fund's duration and yield curve active management strategies. For instance, in the event that long-term interest rates are higher than short-term interest rates, the Fund may elect to pay a floating short-term interest rate and to receive a long-term fixed interest rate for a stipulated period of time, thereby generating payments as a function of the difference between current short-term interest rates and long-term interest rates, so long as the floating short-term interest rate (which may rise) is lower than the fixed long-term interest rate.

The Fund may enter into opposite sides of multiple interest rate swaps or other derivatives with respect to the same underlying reference instrument (e.g., a 10-year U.S. treasury) that have different effective dates with respect to interest accrual time periods also for the principal purpose of generating distributable gains (characterized as ordinary income for tax purposes) that are not part of the Fund's duration or yield curve management strategies. In such a "paired swap transaction," the Fund would generally enter into one or more interest rate swap agreements whereby the Fund agrees to make regular payments starting at the time the Fund enters into the agreements equal to a floating interest rate in return for payments equal to a fixed interest rate (the "initial leg"). The Fund would also enter into one or more interest rate swap agreements on the same underlying instrument, but take the opposite position (i.e., in this example, the Fund would make regular payments equal to a fixed interest rate in return for receiving payments equal to a floating interest rate) with respect to a contract whereby the payment obligations do not commence until a date following the commencement of the initial leg (the "forward leg").

The Fund may engage in investment strategies, including those that employ the use of paired swaps transactions, the use of interest rate swaps to seek to capitalize on differences between short-term and long-term interest rates and other derivatives transactions, to, among other things, seek to generate current, distributable income, even if such strategies could potentially result in declines in the Fund's net asset value ("NAV"). The Fund's income and gain-generating strategies, including certain derivatives strategies, may generate current income and gains taxable as ordinary income sufficient to support quarterly distributions even in situations when the Fund has experienced a decline in net assets due to, for example, adverse changes in the broad U.S. or non-U.S. equity markets or the Fund's debt investments, or arising from its use of derivatives. For instance, a portion of the Fund's quarterly distributions may be sourced from paired swap transactions utilized to produce current distributable ordinary income for tax purposes on the initial leg, with a substantial possibility that the Fund will later realize a corresponding capital loss and potential decline in its NAV with respect to the forward leg (to the extent there are not corresponding offsetting capital gains being generated from other sources). For instance, a portion of the Fund's monthly distributions may be sourced from paired swap transactions utilized to produce current distributable ordinary income for tax purposes on the initial leg, with a substantial possibility that the Fund will later realize a corresponding capital loss and potential decline in its NAV with respect to the forward leg (to the extent there are not corresponding offsetting capital gains being generated from other sources). Because some or all of these transactions may generate capital losses without corresponding offsetting capital gains, portions of the Fund's distributions recognized as ordinary income for tax purposes (such as from paired swap transactions) may be economically similar to a taxable return of capital when considered together with such capital losses.

The notional exposure of the Fund's interest rate derivatives may represent a multiple of the Fund's total assets. There can be no assurance that the Fund's strategies involving interest rate derivatives will work as intended and such strategies are subject to the risks related to the use of derivatives generally, as discussed above (see also Note 6, Financial Derivative Instruments and Note 7, Principal and Other Risks, in the Notes to Financial Statements for further discussion on the use of derivative instruments and certain of the risks associated therewith). The Fund's use of leverage creates the opportunity for increased net income, but also creates special risks for shareholders, including the likelihood of greater volatility of NAV and market price, and of the investment return to shareholders, rather than a comparable portfolio without leverage. To the extent used, there is no assurance that the Fund's leveraging strategies will be successful. Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. Interest expense payable by the Fund with respect to derivatives and other forms of leverage will generally be based on shorter-term interest rates that would be periodically reset. If shorter-term interest rates rise relative to the rate of return on the Fund's portfolio, the interest and other costs to the Fund of leverage could exceed the rate of return on the debt obligations and other investments held by the Fund, thereby reducing return to shareholders. In addition, fees and expenses of any form of leverage used by the Fund will be borne entirely by shareholders and will reduce the investment return of the Fund's shares.

The Fund currently expects, under normal circumstances, to obtain significant exposure to MLPs through the use of total return swaps ("MLP swaps"), and to hold cash and cash equivalents and/or high quality debt instruments in an amount equal to the full notional value of such MLP swaps. To the extent the Fund seeks additional leverage, rather than obtaining additional leverage through

|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022<sub>7</sub> |

---

------

other means, such as the MLP swaps, the Fund expects to utilize reverse repurchase agreements, the net proceeds of which will be invested in accordance with the Fund's investment objectives and policies, including with respect to the Fund's exposure to MLPs. The Fund expects that the additional assets resulting from the use of reverse repurchase agreements will provide the Fund with greater flexibility to invest directly in MLP securities than if the Fund were to obtain leverage through the MLP swaps. Because the fees received by PIMCO are based on the average daily total managed assets of the Fund (including assets attributable to, among other forms of leverage, any reverse repurchase agreements, but not attributable to total return swaps or other derivatives), PIMCO has a financial incentive for the Fund to use certain forms of leverage, such as reverse repurchase agreements, which may create a conflict of interest between PIMCO, on the one hand, and common shareholders, on the other hand. Fees and expenses borne by the Fund with respect to the use of reverse repurchase agreements (including management fees) may be greater than expenses associated with the use of MLP swaps, and may result in a reduction of the NAV of the common shares, and may negatively impact the Fund's performance and/or distribution rate.

There can be no assurance that the Fund's use of leverage will result in a higher yield on its common shares, and it may result in losses. Leverage creates several major types of risks for the Fund's common shareholders, including (1) the likelihood of greater volatility of the NAV and market price of the Fund's common shares, and of the investment return to the Fund's common shareholders, than a comparable portfolio without leverage; (2) the possibility either that the Fund's common share dividends will fall if the interest and other costs of leverage rise, or that dividends paid on the Fund's common shares will fluctuate because such costs vary over time; and (3) the effects of leverage in a declining market or a rising interest rate environment, as leverage is likely to cause a greater decline in the NAV of the Fund's common shares than if the Fund were not leveraged and may result in a greater decline in market value of the Fund's common shares.

The Fund may hold common stocks and other equity securities from time to time, including without limit those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security.

Unless the limited term provision of the Fund's Declaration of Trust is amended by shareholders in accordance with the Declaration of Trust, or unless the Fund completes an Eligible Tender Offer and converts to perpetual existence, the Fund will terminate on or about the Dissolution Date (each as defined in Note 1, Organization, in the Notes to Financial Statements). The Fund is not a so called "target date" or "life cycle" fund whose asset allocation becomes more conservative over time as its target date, often associated with retirement, approaches. In addition, the Fund is not a "target term" fund whose investment objective is to return its original NAV on the Dissolution Date or in an Eligible Tender Offer. Because the assets of the Fund will be liquidated in connection with the dissolution, the Fund will incur transaction costs in connection with dispositions of portfolio securities. The Fund does not limit its investments to securities having a maturity date prior to the Dissolution Date and may be required to sell portfolio securities when it otherwise would not, including at times when market conditions are not favorable, which may cause the Fund to lose money. In particular, the Fund's portfolio may still have large exposures to illiquid securities as the Dissolution Date approaches, and losses due to portfolio liquidation may be significant. Beginning one year before the Dissolution Date (the "Wind-Down Period") the Fund may begin liquidating all or a portion of the Fund's portfolio, and the Fund may deviate from its investment strategy and may not achieve its investment objectives. As a result, during the Wind-Down Period, the Fund's

distributions may decrease, and such distributions may include a return of capital. It is expected that common shareholders will receive cash in any liquidating distribution from the Fund, regardless of their participation in the Fund's automatic dividend reinvestment plan. However, if on the Dissolution Date the Fund owns securities for which no market exists or securities that are trading at depressed prices, such securities may be placed in a liquidating trust. The Fund cannot predict the amount, if any, of securities that will be required to be placed in a liquidating trust. The Fund's investment objectives and policies are not designed to seek to return investors' original investment upon termination of the Fund, and investors may receive more or less than their original investment upon termination of the Fund. As the assets of the Fund will be liquidated in connection with its termination, the Fund may be required to sell portfolio securities when it otherwise would not, including at times when market conditions are not favorable, which may cause the Fund to lose money. If the Fund conducts an Eligible Tender Offer, the Fund anticipates that funds to pay the aggregate price of shares accepted for purchase pursuant to the tender offer will be first derived from any cash on hand and then from the proceeds from the sale of portfolio investments held by the Fund. In addition, the Fund may be required to dispose of portfolio investments in connection with any reduction in the Fund's outstanding leverage necessary in order to maintain the Fund's desired leverage ratios following a tender offer. The risks related to the disposition of securities in connection with the Fund's dissolution also would be present in connection with the disposition of securities in connection with an Eligible Tender Offer. The tax effect of any such dispositions of portfolio investments will depend on the difference between the price at which the investments are sold and the tax basis of the Fund in the investments. If the Fund's tax basis for the investments sold is less than the sale proceeds, the Fund will recognize capital gains, which the Fund will be required to distribute to common shareholders. In addition, the Fund's purchase of tendered Common Shares pursuant to a tender offer will have tax consequences for tendering common shareholders and may have tax consequences for non-tendering common shareholders. See Note 15, Federal Income Tax Matters, in the Notes to Financial Statements for further discussion on tax matters. A tender offer will have the effect of increasing the proportionate interest in the Fund of non-tendering shareholders. All shareholders remaining after a tender offer will be subject to proportionately higher expenses due to the reduction in the Fund's total assets resulting from payment for the tendered shares. Such reduction in the Fund's total assets may also result in less investment flexibility, reduced diversification and greater volatility for the Fund, and may have an adverse effect on the Fund's investment performance. The Fund is not required to conduct an Eligible Tender Offer. If the Fund conducts an Eligible Tender Offer, there can be no assurance that the number of tendered shares would not result in the Fund having aggregate net assets below $200 million (the "the Dissolution Threshold"), in which case the Eligible Tender Offer will be canceled, no shares will be repurchased pursuant to the Eligible Tender Offer and the Fund will dissolve on the Dissolution Date (subject to possible extensions). Following the completion of an Eligible Tender Offer in which the number of tendered shares would result in the Fund having aggregate net assets greater than or equal to the Dissolution Threshold, the Board may eliminate the Dissolution Date without shareholder approval. Thereafter, the Fund will have a perpetual existence. Pacific Investment Management Company LLC ("PIMCO" or the "Manager") may have a conflict of interest in recommending to the Board that the Dissolution Date be eliminated and the Fund have a perpetual existence. The Fund is not required to conduct additional tender offers following an Eligible Tender Offer and conversion to perpetual existence. Therefore, remaining shareholders may not have another opportunity to participate in a tender offer. Shares of closed-end management investment companies frequently trade at a discount

from their NAV, and as a result remaining shareholders may only be able to sell their shares at a discount to NAV. The Fund's exposure to commodities may subject the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. The commodities markets have experienced periods of extreme volatility. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant reductions in values of a variety of commodities and natural resources. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund's holdings.

The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity and natural resources investment prices are outside of the Fund's control and may not be anticipated by the Manager. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; travel restrictions; disease and political turmoil; changing market and economic conditions; market liquidity; weather and climate conditions; changing supply and demand relationships and levels of domestic production and imported commodities; the availability of local, intrastate and interstate transportation systems; energy conservation; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted.

Prices of various commodities and natural resources may also be affected by factors such as drought, floods, weather, livestock disease, changes in storage costs, embargoes, tariffs and other regulatory developments. Many of these factors are very unpredictable. The prices of commodities and natural resources can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Certain commodities or natural resources may be produced in a limited number of countries and may be controlled by a small number of producers or groups of producers. As a result, political, economic and supply related events in such countries could have a disproportionate impact on the prices of such commodities and natural resources.

Fluctuations in energy commodity prices can result from changes in general economic conditions or political circumstances (especially of key energy producing and consuming countries); market conditions; weather patterns; domestic production levels; volume of imports; energy conservation; domestic and foreign governmental regulation; international politics; policies of the Organization of the Petroleum Exporting Countries; taxation; tariffs; and the availability and costs of local, intrastate and interstate transportation methods. The energy sector as a whole may also be impacted by the perception that the performance of energy sector companies is directly linked to commodity prices. High commodity prices may drive further energy conservation efforts, and a slowing economy may adversely impact energy consumption, which may adversely affect the performance of MLPs and other companies operating in the energy sector. Recent economic and market events have fueled concerns regarding potential liquidations of commodity futures and options positions.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures

contract prices which may occur in a single business day (generally referred to as "daily price fluctuation limits"). The maximum or minimum price of a contract as a result of these limits is referred to as a "limit price." If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

The Fund invests in covenant-lite obligations, which contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Covenant-lite loans may carry more risk than traditional loans as they allow individuals and corporations to engage in activities that would otherwise be difficult or impossible under a covenant-heavy loan agreement. In the event of default, covenant-lite loans may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default. The Fund's investments in and exposure to foreign securities involve special risks. For example, the value of these investments may decline in response to unfavorable political and legal developments, unreliable or untimely information or economic and financial instability. Foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. The securities markets of certain foreign countries are relatively small, with a limited number of companies representing a small number of industries. Issuers of foreign securities are usually not subject to the same degree of regulation as U.S. issuers. Reporting, accounting, auditing and custody standards of foreign countries differ, in some cases significantly, from U.S. standards. Also, nationalization, expropriation or other confiscation, currency blockage, political changes or diplomatic developments could adversely affect the Fund's investments in foreign securities. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment in foreign securities. Investing in foreign (non-U.S.) securities may entail risk due to foreign (non-U.S.) economic and political developments; this risk may be increased when investing in emerging markets. For example, if the Fund invests in emerging market debt, it may face increased exposure to interest rate, liquidity, volatility, and redemption risk due to the specific economic, political, geographical, or legal background of the foreign (non-U.S.) issuer.

Classifications of Fund portfolio holdings in this report are made according to financial reporting standards. The classification of a particular portfolio holding as shown in the Allocation Breakdown and Schedule of Investments sections of this report may differ from the classification used for the Fund's compliance calculations, including those used in the Fund's prospectus, investment objectives, regulatory, and other investment limitations and policies, which may be based on different asset class, sector or geographical classifications. The Fund is separately monitored for compliance with respect to prospectus and regulatory requirements.

The geographical classification of foreign (non-U.S.) securities in this report, if any, are classified by the country of incorporation of a holding. In certain instances, a security's country of incorporation may be different from its country of economic exposure.

Beginning in January 2020, global financial markets have experienced and may continue to experience significant volatility resulting from the spread of a novel coronavirus known as COVID-19.

The outbreak of COVID-19 has resulted in travel and border restrictions, quarantines, supply chain disruptions, lower consumer demand and general market uncertainty. In 2022, many countries lifted some or all restrictions related to COVID-19. However, the effects of COVID-19 have and may continue to adversely affect the global economy, the economies of certain nations and individual issuers, all of which may negatively impact the Fund's performance. In addition, COVID-19 and governmental responses to COVID-19 may negatively impact the capabilities of the Fund's service providers and disrupt the Fund's operations.

The United States' enforcement of restrictions on U.S. investments in certain issuers and tariffs on goods from certain other countries has contributed to and may continue to contribute to international trade tensions and may impact portfolio securities. The United States' enforcement of sanctions or other similar measures on various Russian entities and persons, and the Russian government's response, may also negatively impact securities and instruments that are economically tied to Russia.

The United Kingdom's withdrawal from the European Union may impact Fund returns. The withdrawal may cause substantial volatility in foreign exchange markets, lead to weakness in the exchange rate of the British pound, result in a sustained period of market uncertainty, and destabilize some or all of the other European Union member countries and/or the Eurozone.

The Fund may invest in certain instruments that rely in some fashion upon the London Interbank Offered Rate ("LIBOR"). LIBOR is an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. The United Kingdom's Financial Conduct Authority, which regulates LIBOR, has announced plans to ultimately phase out the use of LIBOR. The transition may result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. There remains uncertainty regarding future utilization of LIBOR and the nature of any replacement rate (e.g., the Secured Overnight Financing Rate, which is intended to replace U.S. dollar LIBOR and measures the cost of overnight borrowings through repurchase agreement transactions collateralized with U.S. Treasury securities). Any potential effects of the transition away from LIBOR on the Fund or on certain instruments in which the Fund invests can be difficult to ascertain, and they may vary depending on a variety of factors. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

Investments in loans through a purchase of a loan or a direct assignment of a financial institution's interests with respect to a loan are generally subject to risks similar to those of investments in other types of debt obligations, including, among others, credit risk, interest rate risk, variable and floating rate securities risk, and, as applicable, risks associated with mortgage-related securities. In addition, in many cases loans are subject to the risks associated with below-investment grade securities. In the case of a loan participation or assignment, the Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. As a result, the Fund may be subject to the credit risk of both the borrower and the lender that is selling the loan agreement. In the event of the insolvency of the lender selling a loan participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. The Fund may be subject to heightened or additional risks and potential liabilities and costs by investing in mezzanine and other subordinated loans, including those arising under bankruptcy, fraudulent

conveyance, equitable subordination, lender liability, environmental and other laws and regulations, and risks and costs associated with debt servicing and taking foreclosure actions associated with the loans.

Mortgage-related and other asset-backed instruments represent interests in "pools" of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related assets, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money.

The Fund's investments in other asset-backed instruments are subject to risks similar to those associated with mortgage-related assets, as well as additional risks associated with the nature of the assets and the servicing of those assets. Payment of principal and interest on asset-backed securities may be largely dependent upon the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets. Additionally, investments in subordinate mortgage-backed and other asset-backed instruments will be subject to risks arising from delinquencies and foreclosures, thereby exposing the Fund's investment portfolio to potential losses. Subordinate securities of mortgage-backed and other asset-backed instruments are also subject to greater credit risk than those mortgage-backed or other asset-backed securities that are more highly rated.

The Fund may also invest in the residual or equity tranches of mortgage-related and other asset-backed instruments, which may be referred to as subordinate mortgage-backed or asset-backed instruments and interest-only mortgage-backed or asset-backed instruments. Because an investment in the residual or equity tranche of a mortgage-related or other asset-backed instrument will be the first to bear losses incurred by such instrument, these investments may involve a significantly greater degree of risk than investments in other tranches of a mortgage-related or other asset-backed instruments.

High-yield bonds (commonly referred to as "junk bonds") typically have a lower credit rating than other bonds. Lower-rated bonds generally involve a greater risk to principal than higher-rated bonds. Further, markets for lower-rated bonds are typically less liquid than for higher-rated bonds, and public information is usually less abundant in markets for lower-rated bonds. Thus, high yield investments increase the chance that the Fund will lose money. PIMCO does not rely solely on credit ratings, and develops its own analysis of issuer credit quality. The Fund may purchase unrated securities (which are not rated by a rating agency) if PIMCO determines that the security is of comparable quality to a rated security that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that PIMCO may not accurately evaluate the security's comparative credit quality, which could result in the Fund's portfolio having a higher level of credit and/or high yield risk than PIMCO has estimated or desires for the Fund, and could negatively impact the Fund's performance and/or returns. The Fund may invest a substantial portion of its assets in unrated securities and therefore may be particularly subject to the associated risks. To the extent that the Fund invests in high yield and/or unrated securities, the Fund's success in achieving its investment objectives may depend more heavily on the portfolio manager's

creditworthiness analysis than if the Fund invested exclusively in higher-quality and rated securities. The Fund may hold defaulted securities that may involve special considerations including bankruptcy proceedings, other regulatory and legal restrictions affecting the Fund's ability to trade, and the availability of prices from independent pricing services or dealer quotations. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments.

Defaulted securities are often illiquid and may not be actively traded. Sales of securities in bankrupt companies at an acceptable price may be difficult and differences compared to the value of the securities used by the Fund could be material. The credit quality of a particular security or group of securities does not ensure the stability or safety of the overall portfolio.

Contingent convertible securities ("CoCos") are a form of hybrid debt security issued primarily by non-U.S. issuers, which have loss absorption mechanisms built into their terms. The risks of investing in CoCos include, without limitation, the risk that interest payments will be cancelled by the issuer or a regulatory authority, the risk of ranking junior to other creditors in the event of a liquidation or other bankruptcy-related event as a result of holding subordinated debt, the risk of the Fund's investment becoming further subordinated as a result of conversion from debt to equity, the risk that the principal amount due can be written down to a lesser amount, and the general risks applicable to fixed income investments, including interest rate risk, credit risk, market risk and liquidity risk, any of which could result in losses to the Fund. CoCos may experience a loss absorption mechanism trigger event, which would likely be the result of, or related to, the deterioration of the issuer's financial condition (e.g., a decrease in the issuer's capital ratio) and status as a going concern. In such a case, with respect to CoCos that provide for conversion into common stock upon the occurrence of the trigger event, the market price of the issuer's common stock received by the Fund will have likely declined, perhaps substantially, and may continue to decline, which may adversely affect the Fund's NAV.

Variable and floating rate securities may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. Inverse floating rate securities may decrease in value if interest rates increase. Inverse floating rate securities may also exhibit greater price volatility than a fixed rate obligation with similar credit quality. When the Fund holds variable or floating rate securities, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the NAV of the Fund's shares.

The Fund may make investments in debt instruments and other securities or instruments directly or through one or more direct or indirect fully-owned subsidiaries formed by the Fund (each, a "Subsidiary"). A Subsidiary may invest, for example, in whole loans or in shares, certificates, notes or other securities representing the right to receive principal and interest payments due on fractions of whole loans or pools of whole loans, or any other security or other instrument that the parent Fund may hold directly.

The Fund may seek to gain exposure to commodities through investments in swap agreements, futures and options, and through investments in PIMCO Cayman Commodity Fund IX, Ltd., a Subsidiary organized under the laws of the Cayman Islands (the "Cayman Subsidiary"). The Fund may invest up to 25% of its total assets in the Cayman Subsidiary. The Cayman Subsidiary is advised by PIMCO and has the same investment objectives as the Fund. The Cayman Subsidiary (unlike the Fund) may invest without limit in commodity-linked swap agreements and other commodity-linked derivative instruments.

References herein to the Fund include references to a Subsidiary in respect of the Fund's investment exposure. The allocation of the Fund's assets to a Subsidiary will vary over time and the Fund's portfolio may not always include all of the different types of investments described herein. By investing through its Subsidiaries, the Fund is exposed to the risks associated with the Subsidiaries' investments. The Subsidiaries are not registered as investment companies under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder (the "Act"), and are not subject to all of the investor protections of the Act, although each Subsidiary is managed pursuant to the compliance policies and procedures of the Fund applicable to it. Changes in the laws of the United States and/or the jurisdiction in which a Subsidiary is organized could result in the inability of the Fund and/or the Subsidiary to operate as described in this report and could adversely affect the Fund. There is no guarantee that the investment objectives of the Subsidiaries will be achieved.

As the use of technology has become more prevalent in the course of business, the Fund has become potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events that may, among other things, cause the Fund to lose proprietary information, suffer data corruption and/or destruction or lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations.

Cyber security failures or breaches may result in financial losses to the Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with the Fund's ability to calculate its NAV, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

The common shares of the Fund trade on the New York Stock Exchange. As with any stock, the price of the Fund's common shares will fluctuate with market conditions and other factors. If you sell your common shares of the Fund, the price received may be more or less than your original investment. Shares of closed-end management investment companies, such as the Fund, frequently trade at a discount from their NAV and may trade at a price that is less than the initial offering price and/or the NAV of such shares. Further, if the Fund's shares trade at a price that is more than the initial offering price and/or the NAV of such shares, including at a substantial premium and/or for an extended period of time, there is no assurance that any such premium will be sustained for any period of time and will not decrease, or that the shares will not trade at a discount to NAV thereafter.

The Fund may be subject to various risks. *A description of certain of these risks is available in the Notes to Financial Statements of this report.*

On the Fund Summary page in this Shareholder Report, the Average Annual Total Return table and Cumulative Returns chart measure performance assuming that any dividend and capital gain distributions were reinvested. Total return is calculated by determining the percentage change in NAV or market price (as applicable) in the specific period. Returns do not reflect the deduction of taxes that a shareholder would pay on (i) Fund distributions or (ii) the sale of Fund shares. Total

return for a period of more than one year represents the average annual total return. Performance at market price will differ from results at NAV. Although market price returns tend to reflect investment results over time, during shorter periods returns at market price can also be influenced by factors such as changing views about the Fund, market conditions, supply and demand for the Fund's shares, or changes in the Fund's dividends. Performance shown is net of fees and expenses. Historical NAV performance for the Fund may have been positively impacted by fee waivers or expense limitations in place during some or all of the periods shown, if applicable. Future performance (including total return or yield) and distributions may be negatively impacted by the expiration or reduction of any such fee waivers or expense limitations.

The Fund's quarterly distributions may include, among other possible sources, interest income from its debt portfolio and payments and premiums (characterized as capital for financial accounting purposes and as ordinary income for tax purposes) generated by certain types of interest rate derivatives.

The dividend rate that the Fund pays on its common shares may vary as portfolio and market conditions change, and will depend on a number of factors, including without limit the amount of the Fund's undistributed net investment income and net short- and long-term capital gains, as well as the costs of any leverage obtained by the Fund. As portfolio and market conditions change, the rate of distributions on the common shares and the Fund's dividend policy could change. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund's distribution rate or that the rate will be sustainable in the future.

An investment in the Fund is not a bank deposit and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money on investments in the Fund.

The Trustees are responsible generally for overseeing the management of the Fund. The Trustees authorize the Fund to enter into service agreements with the Manager and other service providers in order to provide, and in some cases authorize service providers to procure through other parties, necessary or desirable services on behalf of the Fund. Shareholders are not parties to or third-party beneficiaries of such service agreements. Neither the Fund's original or any subsequent prospectus or Statement of Additional Information ("SAI"), any press release or shareholder report, any contracts filed as exhibits to the Fund's registration statement, nor any other communications, disclosure documents or regulatory filings (including this report) from or on behalf of the Fund creates a contract between or among any shareholders of the Fund, on the one hand, and the Fund, a service provider to the Fund, and/or the Trustees or officers of the Fund, on the other hand.

The Trustees (or the Fund and its officers, service providers or other delegates acting under authority of the Trustees) may amend its most recent prospectus or use a new prospectus or SAI with respect to the Fund, adopt and disclose new or amended policies and other changes in press releases and shareholder reports and/or amend, file and/or issue any other communications, disclosure documents or regulatory filings, and may amend or enter into any contracts to which the Fund is a party, and interpret the investment objective(s), policies, restrictions and contractual provisions applicable to the

Fund, without shareholder input or approval, except in circumstances in which shareholder approval is specifically required by law (such as changes to fundamental investment policies) or where a shareholder approval requirement was specifically disclosed in the Fund's prospectus, SAI or shareholder report and is otherwise still in effect.

PIMCO has adopted written proxy voting policies and procedures ("Proxy Policy") as required by Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended. The Proxy Policy has been adopted by the Fund as the policies and procedures that PIMCO will use when voting proxies on behalf of the Fund.

A description of the policies and procedures that PIMCO uses to vote proxies relating to portfolio securities of the Fund, and information about how the Fund voted proxies relating to portfolio securities held during the most recent twelve-month period ended June 30th, are available without charge, upon request, by calling the Fund at (844) 33-PIMCO, on the Fund's website at www.pimco.com, and on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

The Fund files portfolio holdings information with the SEC on Form N-PORT within 60 days of the end of each fiscal quarter. The Fund's complete schedule of securities holdings as of the end of each fiscal quarter will be made available to the public on the SEC's website at www.sec.gov and on PIMCO's website at www.pimco.com, and will be made available, upon request, by calling PIMCO at (844) 33-PIMCO.

SEC rules allow the Fund to deliver shareholder reports to be delivered to investors by providing access to such reports online free of charge and by mailing a notice that the report is electronically available. Investors may elect to receive all reports in paper free of charge by contacting their financial intermediary or, if invested directly with the Fund, investors can inform the Fund by calling (844) 33-PIMCO. Any election to receive reports in paper will apply to all funds held with the fund complex if invested directly with the Fund or to all funds held in the investor's account if invested through a financial intermediary.

In April 2020, the SEC adopted amended rules modifying the registration, communications, and offering processes for registered closed-end funds and interval funds. Among other things, the amendments: (1) permit qualifying closed-end funds to use a short-form registration statement to offer securities in eligible transactions and certain funds to qualify as Well Known Seasoned Issuers; (2) permit interval funds to pay registration fees based on net issuance of shares in a manner similar to mutual funds; (3) require closed-end funds and interval funds to include additional disclosures in their annual reports; and (4) require certain information to be filed in interactive data format. The new rules have phased compliance, with some requirements having already taken effect and others requiring compliance as late as February 1, 2023.

In October 2020, the SEC adopted a rule related to the use of derivatives, short sales, reverse repurchase agreements and certain other transactions by registered investment companies that rescinds and withdraws prior guidance of the SEC and its staff regarding asset segregation and cover transactions. Subject to certain exceptions, the rule requires funds that trade derivatives and other transactions that create future payment or delivery obligations to comply with a value-at-risk leverage limit and certain derivatives risk management program and reporting requirements. These requirements may limit the ability of the Fund to use derivatives and reverse repurchase agreements and similar financing transactions as part of their investment strategies and may increase the cost of

the Fund's investments and cost of doing business, which could adversely affect investors. The rule went into effect on February 19, 2021. The compliance date for the new rule and related reporting requirements was August 19, 2022.

In October 2020, the SEC adopted a rule regarding the ability of a fund to invest in other funds. The rule allows a fund to acquire shares of another fund in excess of certain limitations currently imposed by the Investment Company Act of 1940 (the "Act") without obtaining individual exemptive relief from the SEC, subject to certain conditions. The rule also includes the rescission of certain exemptive relief from the SEC and guidance from the SEC staff for funds to invest in other funds. The effective date for the rule was January 19, 2021, and the compliance date for the rule was January 19, 2022.

In December 2020, the SEC adopted a rule addressing fair valuation of fund investments. The new rule sets forth requirements for good faith determinations of fair value as well as for the performance of fair value determinations, including related oversight and reporting obligations. The new rule also defines "readily available market quotations" for purposes of the definition of "value" under the Act, and the SEC noted that this definition will apply in all contexts under the Act. The effective date for the rule was March 8, 2021. The compliance date for the new rule and the related reporting requirements was September 8, 2022.

In May 2022, the SEC proposed amendments to a current rule governing fund naming conventions. In general, the current rule requires funds with certain types of names to adopt a policy to invest at least 80% of their assets in the type of investment suggested by the name. The proposed amendments would expand the scope of the current rule in a number of ways that would result in an expansion of the types of fund names that would require the fund to adopt an 80% investment policy under the rule. Additionally, the proposed amendments would modify the circumstances under which a fund may deviate from its 80% investment policy and address the use and valuation of derivatives instruments for purposes of the rule. The proposal's impact on the Fund will not be known unless and until any final rulemaking is adopted.

In May 2022, the SEC proposed a framework that would require certain registered funds (such as the Fund) to disclose their environmental, social, and governance ("ESG") investing practices. Among other things, the proposed requirements would mandate that funds meeting three pre-defined classifications (i.e., integrated, ESG focused and/or impact funds) provide prospectus and shareholder report disclosure related to the ESG factors, criteria and processes used in managing the fund. The proposal's impact on the Fund will not be known unless and until any final rulemaking is adopted.

In October 2022, the SEC adopted changes to the mutual fund and exchange-traded fund ("ETF") shareholder report and registration statement disclosure requirements and the registered fund advertising rules, which will impact the disclosures provided to shareholders. The rule amendments are effective as of January 24, 2023, but the SEC is providing an 18-month compliance period following the effective date for such amendments other than those addressing fee and expense information in advertisements that might be materially misleading.

In November 2022, the SEC adopted amendments to Form N-PX under the Act to improve the utility to investors of proxy voting information reported by mutual funds, ETFs and certain other funds. The rule amendments will expand the scope of funds' Form N-PX reporting obligations, subject managers to Form N-PX reporting obligations for "Say on Pay" votes, enhance Form N-PX disclosures, permit joint reporting by funds, managers and affiliated managers on Form N-PX; and require website availability of fund proxy voting records. The amendments will become effective on July 1, 2024. Funds and managers will be required to file their first reports covering the period from July 1, 2023 to June 30, 2024 on amended Form N-PX by August 31, 2024.

\* Cumulative return.

<sup>(1)</sup> Performance quoted represents past performance. Past performance is not a guarantee or a reliable indicator of future results. Current performance may be lower or higher than performance shown. Investment return and the principal value of an investment will fluctuate. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares. Total return, market price, NAV, market price distribution rate, and NAV distribution rate will fluctuate with changes in market conditions. Performance current to the most recent month-end is available at www.pimco.com or via (844) 33-PIMCO. Performance is calculated assuming all dividends and distributions are reinvested at prices obtained under the Fund's dividend reinvestment plan. Performance does not reflect any brokerage commissions in connection with the purchase or sale of Fund shares.

<sup>(2)</sup> Distribution rates are not performance and are calculated by annualizing the most recent distribution per share and dividing by the NAV or Market Price, as applicable, as of the reported date. Distributions may be comprised of ordinary income, net capital gains, and/or a return of capital (ROC) of your investment in the Fund. Because the distribution rate may include a ROC, it should not be confused with yield or income. If the Fund estimates that a portion of its distribution may be comprised of amounts from sources other than net investment income in accordance with its policies and good accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Please visit www.pimco.com for most recent Section 19 Notice, if applicable. Final determination of a distribution's tax character will be provided to shareholders when such information is available.

Total effective leverage consists of preferred shares, reverse repurchase agreements and other borrowings, credit default swap notional and floating rate notes issued in tender option bond transactions, as applicable (collectively "Total Effective Leverage"). The Fund may engage in other transactions not included in Total Effective Leverage disclosed above that may give rise to a form of leverage, including certain derivative transactions. For the

Each common shareholder would be paid a pro rata portion of the Fund's net assets upon termination of the Fund. The Board may, by a Board Action Vote, cause the Fund to conduct a tender offer, as of a date within twelve months preceding the Dissolution Date (as may be extended as described above), to all common shareholders to purchase 100% of the then outstanding common shares of the Fund at a price equal to the net asset value ("NAV") per common share on the expiration date of the tender offer (an "Eligible Tender Offer"). The Board has established that the Fund must have at least $200 million of net assets immediately following the completion of an Eligible Tender Offer to ensure the continued viability of the Fund.

Hereinafter, the Board of Trustees of the Fund shall be collectively referred to as the "Board."

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The Fund is treated as an investment company under the reporting requirements of U.S. GAAP. The functional and reporting currency for the Fund is the U.S. dollar. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

(a) Securities Transactions and Investment Income Securities transactions are recorded as of the trade date for financial reporting purposes. Securities purchased or sold on a when-issued or delayed-delivery basis may be settled beyond a standard settlement period for the security after the trade date. Realized gains (losses) from securities sold are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date, except certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Interest income, adjusted for the accretion of discounts and amortization of

#### Notes to Financial Statements (Cont.)
premiums, is recorded on the accrual basis from settlement date, with the exception of securities with a forward starting effective date, where interest income is recorded on the accrual basis from effective date. For convertible securities, premiums attributable to the conversion feature are not amortized. Estimated tax liabilities on certain foreign securities are recorded on an accrual basis and are reflected as components of interest income or net change in unrealized appreciation (depreciation) on investments on the Consolidated Statement of Operations, as appropriate. Tax liabilities realized as a result of such security sales are reflected as a component of net realized gain (loss) on investments on the Consolidated Statement of Operations. Paydown gains (losses) on mortgage-related and other asset-backed securities, if any, are recorded as components of interest income on the Consolidated Statement of Operations. Income or short-term capital gain distributions received from registered investment companies, if any, are recorded as dividend income. Long-term capital gain distributions received from registered investment companies, if any, are recorded as realized gains.

(b) Foreign Currency Translation The market values of foreign securities, currency holdings and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the current exchange rates each business day. Purchases and sales of securities and income and expense items denominated in foreign currencies, if any, are translated into U.S. dollars at the exchange rate in effect on the transaction date. The Fund does not separately report the effects of changes in foreign exchange rates from changes in market prices on securities held. Such changes are included in net realized gain (loss) and net change in unrealized appreciation (depreciation) from investments on the Consolidated Statement of Operations. The Fund may invest in foreign currency-denominated securities and may engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time or through a forward foreign currency contract. Realized foreign exchange gains (losses) arising from sales of spot foreign currencies, currency gains (losses) realized between the trade and settlement dates on securities transactions and the difference between the recorded amounts of dividends, interest, and foreign withholding taxes and the U.S. dollar equivalent of the amounts actually received or paid are included in net realized gain (loss) on foreign currency transactions on the Consolidated Statement of Operations. Net unrealized foreign exchange gains (losses) arising from changes in foreign exchange rates on foreign denominated assets and liabilities other than investments in securities held at the end of the reporting period are included in net change in unrealized appreciation (depreciation) on foreign currency assets and liabilities on the Consolidated Statement of Operations.

(c) Distributions — Common Shares Distributions from net investment income, if any, are declared and distributed to shareholders quarterly. The Fund generally distributes each year all of its net investment income and net short-term capital gains. In addition, at least annually, the Fund generally distributes net realized long-term capital gains not previously distributed, if any. The Fund may revise its distribution policy or postpone the payment of distributions at any time.

The Funds may invest in one or more wholly-owned subsidiaries (each a "Subsidiary" and collectively the "Subsidiaries") that are treated as disregarded entities for U.S. federal income tax purposes. In the case of a Subsidiary that is so treated, for U.S. federal income tax purposes, (i) the Fund is treated as owning the Subsidiary's assets directly; (ii) any income, gain, loss, deduction or other tax items arising in respect of the Subsidiary's assets will be treated as if they are realized or incurred, as applicable, directly by the Fund; and (iii) distributions, if any, the Fund receives from the Subsidiary will have no effect on the Fund's U.S. federal income tax liability.

PIMCO Cayman Commodity Fund IX, Ltd., a Subsidiary organized under the laws of the Cayman Islands (the "Cayman Subsidiary"), will be treated as a controlled foreign corporation. As a result,

(Unaudited)

December 31, 2022

the Fund will be required to include in gross income for U.S. federal income tax purposes all of its Cayman Subsidiary's "subpart F income," whether or not such income is distributed by such Cayman Subsidiary. It is expected that all of the Cayman Subsidiary's income and realized gains and mark-to-market gains will be "subpart F income." The Fund's recognition of its Cayman Subsidiary's "subpart F income" will increase such Fund's tax basis in its Cayman Subsidiary. Distributions by the Cayman Subsidiary to its Fund will be tax-free, to the extent of its previously undistributed "subpart F income," and will correspondingly reduce the Fund's tax basis in its Cayman Subsidiary. "Subpart F income" is generally treated by the Fund as ordinary income, regardless of the character of the Cayman Subsidiary's underlying income or gains. If a net loss is realized by the Cayman Subsidiary, such loss is not generally available to offset the income earned by the Cayman Subsidiary's parent Fund, and such loss cannot be carried forward to offset taxable income of the parent Fund or the Cayman Subsidiary in future periods.

The Fund may engage in investment strategies, including those that employ the use of derivatives, to, among other things, seek to generate current, distributable income without regard to possible declines in the Fund's NAV. The Fund's income and gain generating strategies, including certain derivatives strategies, may generate current, distributable income, even if such strategies could potentially result in declines in the Fund's NAV. The Fund's income and gain- generating strategies, including certain derivatives strategies, may generate current taxable income and gains sufficient to support quarterly distributions even in situations when the Fund has experienced a decline in net assets due to, for example, adverse changes in the broad U.S. or non-U.S. equity markets or the Fund's debt investments, or arising from its use of derivatives. The Fund may enter into opposite sides of interest rate swaps and other derivatives for the principal purpose of generating distributable gains on the one side (characterized as ordinary income for tax purposes) that are not part of the Fund's duration or yield curve management strategies, and with a substantial possibility that the Fund will experience a corresponding capital loss and decline in NAV with respect to the opposite side transaction (to the extent it does not have corresponding offsetting capital gains). Consequently, common shareholders may receive distributions and owe tax on amounts that are effectively a taxable return of the shareholder's investment in the Fund at a time when their investment in the Fund has declined in value, which may be taxed at ordinary income rates. The tax treatment of certain derivatives in which the Fund invests may be unclear and thus subject to recharacterization. Any recharacterization of payments made or received by the Fund pursuant to derivatives potentially could affect the amount, timing or character of Fund distributions. In addition, the tax treatment of such investment strategies may be changed by regulation or otherwise.

Income distributions and capital gain distributions are determined in accordance with income tax regulations which may differ from U.S. GAAP. Differences between tax regulations and U.S. GAAP may cause timing differences between income and capital gain recognition. Further, the character of investment income and capital gains may be different for certain transactions under the two methods of accounting. As a result, income distributions and capital gain distributions declared during a fiscal period may differ significantly from the net investment income (loss) and realized gains (losses) reported on the Fund's annual financial statements presented under U.S. GAAP.

Separately, if the Fund determines or estimates, as applicable, that a portion of a distribution may be comprised of amounts from sources other than net investment income in accordance with its policies, accounting records (if applicable), and accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. For these purposes, the Fund determines or estimates, as applicable, the source or sources from which a distribution is paid,

---

| | | |
|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **43** |

---

------

to the close of the period as of which it is paid, in reference to its internal accounting records and related accounting practices. If, based on such accounting records and practices, it is determined or estimated, as applicable, that a particular distribution does not include capital gains or paid-in surplus or other capital sources, a Section 19 Notice generally would not be issued. It is important to note that differences exist between the Fund's daily internal accounting records and practices, the Fund's financial statements presented in accordance with U.S. GAAP, and recordkeeping practices under income tax regulations. For instance, the Fund's internal accounting records and practices may take into account, among other factors, tax-related characteristics of certain sources of distributions that differ from treatment under U.S. GAAP. Examples of such differences may include, but are not limited to, for certain funds, the treatment of periodic payments under interest rate swap contracts. Accordingly, among other consequences, it is possible that the Fund may not issue a Section 19 Notice in situations where the Fund's financial statements prepared later and in accordance with U.S. GAAP and/or the final tax character of those distributions might later report that the sources of those distributions included capital gains and/or a return of capital. Please visit www.pimco.com for the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Final determination of a distribution's tax character will be provided to shareholders when such information is available.

Distributions classified as a tax basis return of capital at the Fund's fiscal year end, if any, are reflected on the Consolidated Statements of Changes in Net Assets and have been recorded to paid in capital on the Consolidated Statement of Assets and Liabilities. In addition, other amounts have been reclassified between distributable earnings (accumulated loss) and paid in capital on the Consolidated Statement of Assets and Liabilities to more appropriately conform U.S. GAAP to tax characterizations of distributions.

(d) New Accounting Pronouncements and Regulatory Updates In March 2020, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update ("ASU"), ASU 2020-04, which provides optional guidance to ease the potential accounting burden associated with transitioning away from the London Interbank Offered Rate and other reference rates that are expected to be discontinued. ASU 2020-04 is effective for certain reference rate-related contract modifications that occurred during the period March 12, 2020 through December 31, 2022. In March 2021, the administrator for LIBOR announced the extension of the publication of a majority of the USD LIBOR settings to June 30, 2023. In December 2022, FASB issued ASU 2022-06, which includes amendments to extend the duration of the LIBOR transition relief to December 31, 2024, after which entities will no longer be permitted to apply the reference rate reform relief. Management is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Fund's investments and has determined that it is unlikely the ASU's adoption will have a material impact on the Fund's financial statements.

In October 2020, the U.S. Securities and Exchange Commission ("SEC") adopted a rule related to the use of derivatives, short sales, reverse repurchase agreements and certain other transactions by registered investment companies that rescinds and withdraws the guidance of the SEC and its staff regarding asset segregation and cover transactions. Subject to certain exceptions, the rule requires funds that trade derivatives and other transactions that create future payment or delivery obligations to comply with a value-at-risk leverage limit and certain derivatives risk management program and reporting requirements. The effective date for the rule was February 19, 2021. The compliance date for the new rule and the related reporting requirements was August 19, 2022. Management has implemented changes in connection with the rule and has determined that there is no material impact to the Fund's financial statements.

In December 2020, the SEC adopted a rule addressing fair valuation of fund investments. The new rule sets forth requirements for good faith determinations of fair value as well as for the performance of fair value determinations, including related oversight and reporting obligations. The new rule also defines "readily available market quotations" for purposes of the definition of "value" under the Act, and the SEC noted that this definition would apply in all contexts under the Act. The effective date for the rule was March 8, 2021. The compliance date for the new rule and the related reporting requirements was September 8, 2022. Management has implemented changes in connection with the rule and has determined that there is no material impact to the Fund's financial statements.

In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820), which affects all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring the fair value. The amendments also require additional disclosures for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The effective date for the amendments in ASU 2022-03 is for fiscal years beginning after December 15, 2023 and interim periods within those fiscal years. At this time, management is evaluating the implications of these changes on the financial statements.

In October 2022, the SEC adopted changes to the mutual fund and ETF shareholder report and registration statement disclosure requirements and the registered fund advertising rules, which will change the disclosures provided to shareholders. The rule is effective as of January 24, 2023, but the SEC is providing an 18-month compliance period after the effective date other than for rule amendments addressing fee and expense information in advertisements that might be materially misleading. At this time, management is evaluating the implications of these changes on the financial statements.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

(a) Investment Valuation Policies The NAV of a Fund's shares, or each of its share classes as applicable, is determined by dividing the total value of portfolio investments and other assets attributable to the Fund or class, less any liabilities, as applicable, by the total number of shares outstanding.

On each day that the New York Stock Exchange ("NYSE") is open, the Fund's shares are ordinarily valued as of the close of regular trading (normally 4:00 p.m., Eastern time) ("NYSE Close"). Information that becomes known to the Fund or its agents after the time as of which NAV has been calculated on a particular day will not generally be used to retroactively adjust the price of a security or the NAV determined earlier that day. If regular trading on the NYSE closes earlier than scheduled, the Fund may calculate its NAV as of the earlier closing time or calculate its NAV as of the NYSE Close for that day. The Fund generally does not calculate its NAV on days on which the NYSE is not open for business. If the NYSE is closed on a day it would normally be open for business, the Fund may calculate its NAV as of the NYSE Close for such day or such other time that the Fund may determine.

For purposes of calculating NAV, portfolio securities and other assets for which market quotations are readily available are valued at market value. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that the

| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **45** |

---

------

Fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. Market value is generally determined on the basis of official closing prices or the last reported sales prices. The Fund will normally use pricing data for domestic equity securities received shortly after the NYSE Close and does not normally take into account trading, clearances or settlements that take place after the NYSE Close. A foreign (non-U.S.) equity security traded on a foreign exchange or on more than one exchange is typically valued using pricing information from the exchange considered by PIMCO to be the primary exchange. If market value pricing is used, a foreign (non-U.S.) equity security will be valued as of the close of trading on the foreign exchange, or the NYSE Close, if the NYSE Close occurs before the end of trading on the foreign exchange.

Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the Act. As a general principle, the fair value of a security or other asset is 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. Pursuant to Rule 2a-5, the Board has designated PIMCO as the valuation designee ("Valuation Designee") for the Fund to perform the fair value determination relating to all Fund investments. PIMCO may carry out its designated responsibilities as Valuation Designee through various teams and committees. The Valuation Designee's policies and procedures govern the Valuation Designee's selection and application of methodologies for determining and calculating the fair value of Fund investments. The Valuation Designee may value Fund portfolio securities for which market quotations are not readily available and other Fund assets utilizing inputs from pricing services, quotation reporting systems, valuation agents and other third-party sources (together, "Pricing Sources").

Domestic and foreign (non-U.S.) fixed income securities, non-exchange traded derivatives, and equity options are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources using data reflecting the earlier closing of the principal markets for those securities. Prices obtained from Pricing Sources may be based on, among other things, information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Certain fixed income securities purchased on a delayed-delivery basis are marked to market daily until settlement at the forward settlement date. Exchange-traded options, except equity options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Swap agreements are valued on the basis of bid quotes obtained from brokers and dealers or market-based prices supplied by Pricing Sources. With respect to any portion of the Fund's assets that are invested in one or more open-end management investment companies (other than ETFs), the Fund's NAV will be calculated based on the NAVs of such investments.

If a foreign (non-U.S.) equity security's value has materially changed after the close of the security's primary exchange or principal market but before the NYSE Close, the security may be valued at fair value. Foreign (non-U.S.) equity securities that do not trade when the NYSE is open are also valued at fair value. With respect to foreign (non-U.S.) equity securities, the Fund may determine the fair value of investments based on information provided by Pricing Sources, which may recommend fair value or adjustments with reference to other securities, indexes or assets. In considering whether fair valuation is required and in determining fair values, the Valuation Designee may, among other things, consider significant events (which may be considered to include changes in the value of U.S. securities or securities indexes) that occur after the close of the relevant market and before the NYSE Close. The Fund may utilize modeling tools provided by third-party vendors to determine fair

December 31, 2022

values of foreign (non-U.S.) securities. For these purposes, unless otherwise determined by the Valuation Designee, any movement in the applicable reference index or instrument ("zero trigger") between the earlier close of the applicable foreign market and the NYSE Close may be deemed to be a significant event, prompting the application of the pricing model (effectively resulting in daily fair valuations). Foreign exchanges may permit trading in foreign (non-U.S.) equity securities on days when the Fund is not open for business, which may result in the Fund's portfolio investments being affected when shareholders are unable to buy or sell shares.

Whole loans may be fair valued using inputs that take into account borrower- or loan-level data (e.g., credit risk of the borrower) that is updated periodically throughout the life of each individual loan; any new borrower- or loan-level data received in written reports periodically by the Fund normally will be taken into account in calculating the NAV. The Fund's whole loan investments, including those originated by the Fund, generally are fair valued in accordance with procedures approved by the Board.

Investments valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from Pricing Sources. As a result, the value of such investments and, in turn, the NAV of the Fund's shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of investments traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the Fund is not open for business. As a result, to the extent that the Fund holds foreign (non-U.S.) investments, the value of those investments may change at times when shareholders are unable to buy or sell shares and the value of such investments will be reflected in the Fund's next calculated NAV.

Fair valuation may require subjective determinations about the value of a security. While the Fund's and Valuation Designee's policies and procedures are intended to result in a calculation of the Fund's NAV that fairly reflects security values as of the time of pricing, the Fund cannot ensure that fair values accurately reflect the price that the Fund could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by the Fund may differ from the value that would be realized if the securities were sold.

(b) Fair Value Hierarchy U.S. GAAP describes fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes a fair value hierarchy that prioritizes inputs to valuation methods and requires disclosure of the fair value hierarchy, separately for each major category of assets and liabilities, that segregates fair value measurements into levels (Level 1, 2, or 3). The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Levels 1, 2, and 3 of the fair value hierarchy are defined as follows:

<sup>∎</sup> Level 1 — Quoted prices (unadjusted) in active markets or exchanges for identical assets and liabilities.

---

| | |
|:---|:---|
| <sup>∎</sup> | Level 2 — Significant other observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs.  |

---

---

| | | |
|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **47** |

---

------

<sup>∎</sup> Level 3 — Significant unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, which may include assumptions made by the Valuation Designee that are used in determining the fair value of investments.

In accordance with the requirements of U.S. GAAP, the amounts of transfers into and out of Level 3, if material, are disclosed in the Notes to Consolidated Schedule of Investments for the Fund.

For fair valuations using significant unobservable inputs, U.S. GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to realized gain (loss), unrealized appreciation (depreciation), purchases and sales, accrued discounts (premiums), and transfers into and out of the Level 3 category during the period. The end of period value is used for the transfers between Levels of the Fund's assets and liabilities. Additionally, U.S. GAAP requires quantitative information regarding the significant unobservable inputs used in the determination of fair value of assets or liabilities categorized as Level 3 in the fair value hierarchy. In accordance with the requirements of U.S. GAAP, a fair value hierarchy, and if material, a Level 3 reconciliation and details of significant unobservable inputs, have been included in the Notes to Consolidated Schedule of Investments for the Fund.

(c) Valuation Techniques and the Fair Value Hierarchy

Level 1, Level 2 and Level 3 trading assets and trading liabilities, at fair value The valuation methods (or "techniques") and significant inputs used in determining the fair values of portfolio securities or other assets and liabilities categorized as Level 1, Level 2 and Level 3 of the fair value hierarchy are as follows:

Common stocks, ETFs, exchange-traded notes and financial derivative instruments, such as futures contracts, rights and warrants, or options on futures that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy.

Investments in registered open-end investment companies (other than ETFs) will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in unregistered open-end investment companies will be calculated based upon the NAVs of such investments and are considered Level 1 provided that the NAVs are observable, calculated daily and are the value at which both purchases and sales will be conducted.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities and non-U.S. bonds are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The Pricing Sources' internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis or as a repurchase commitment in a sale-buyback transaction are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the NYSE Close. These securities are valued using Pricing Sources that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain exchange traded futures and options to account for market movement between the exchange settlement and the NYSE close. These securities are valued using quotes obtained from a quotation reporting system, established market makers or Pricing Sources. Financial derivatives using these valuation adjustments are categorized as Level 2 of the fair value hierarchy.

Equity exchange-traded options and over the counter financial derivative instruments, such as forward foreign currency contracts and options contracts derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of quotes obtained from a quotation reporting system, established market makers or Pricing Sources (normally determined as of the NYSE Close). Depending on the product and the terms of the transaction, financial derivative instruments can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as quoted prices, issuer details, indices, bid/ask spreads, interest rates, implied volatilities, yield curves, dividends and exchange rates. Financial derivative instruments that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Centrally cleared swaps and over the counter swaps derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. They are valued using a broker-dealer bid quotation or on market-based prices provided by Pricing Sources (normally determined as of the NYSE Close). Centrally cleared swaps and over the counter swaps can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models may use inputs that are observed from actively quoted markets such as the overnight index swap rate, LIBOR forward rate, interest rates, yield curves and credit spreads. These securities are categorized as Level 2 of the fair value hierarchy.

If third-party evaluated vendor pricing is not available or not deemed to be indicative of fair value, the Manager may elect to obtain Broker Quotes directly from the broker-dealer or passed through from a third-party vendor. In the event that fair value is based upon a single sourced Broker Quote, these securities are categorized as Level 3 of the fair value hierarchy. Broker Quotes are typically received from established market participants. Although independently received, the Manager does not have the transparency to view the underlying inputs which support the market quotation. Significant changes in the Broker Quote would have direct and proportional changes in the fair value of the security.

The Discounted Cash Flow model is based on future cash flows generated by the investment and may be normalized based on expected investment performance. Future cash flows are discounted to present value using an appropriate rate of return, typically calibrated to the initial transaction date and adjusted based on Capital Asset Pricing Model and/or other market-based inputs. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

The Comparable Companies model is based on application of valuation multiples from publicly traded comparable companies to the financials of the subject company. Adjustments may be made to the market-derived valuation multiples based on differences between the comparable companies and the subject company. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Short-term debt instruments (such as commercial paper) having a remaining maturity of 60 days or less may be valued at amortized cost, so long as the amortized cost value of such short-term debt instruments is approximately the same as the fair value of the instrument as determined without the use of amortized cost valuation. These securities are categorized as Level 2 or Level 3 of the fair value hierarchy depending on the source of the base price.

When a fair valuation method is applied by PIMCO that uses significant unobservable inputs, investments will be priced by a method that the Valuation Designee believes reflects fair value and are categorized as Level 3 of the fair value hierarchy.

The Fund may utilize the investments and strategies described below to the extent permitted by the Fund's investment policies.

Exchange-Traded Funds typically are index-based investment companies that hold substantially all of their assets in securities representing their specific index, but may also be actively-managed investment companies. Shares of ETFs trade throughout the day on an exchange and represent an investment in a portfolio of securities and other assets. As a shareholder of another investment company, the Fund (and Underlying PIMCO Funds) would bear their pro rata portion of the other investment company's expenses, including advisory fees, in addition to the expenses the Fund (and Underlying PIMCO Funds) bears directly in connection with their own operations. Investments in ETFs

entail certain risks; in particular, investments in index ETFs involve the risk that the ETF's performance may not track the performance of the index the ETF is designed to track.

Loans and Other Indebtedness, Loan Participations and Assignments are direct debt instruments which are interests in amounts owed to lenders or lending syndicates by corporate, governmental, or other borrowers. The Fund's investments in loans may be in the form of direct investments, participations in loans or assignments of all or a portion of loans from third parties or exposure to investments in loans through investments in a mutual fund or other pooled investment vehicle. A loan is often administered by a bank or other financial institution (the "agent") that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. The Fund may invest in multiple series or tranches of a loan, which may have varying terms and carry different associated risks. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. As a result, the Fund may be subject to the credit risk of both the borrower and the agent that is selling the loan agreement.

In the event of the insolvency of the agent selling a participation, the Fund may be treated as a general creditor of the agent and may not benefit from any set-off between the agent and the borrower. When the Fund purchases assignments from agents it acquires direct rights against the borrowers of the loans. These loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans are generally subject to risks similar to those of investments in other types of debt obligations, including, among others, credit risk, interest rate risk, variable and floating rate securities risk, and risks associated with mortgage-related securities. In addition, in many cases loans are subject to the risks associated with below-investment grade securities. The Fund may be subject to heightened or additional risks and potential liabilities and costs by investing in mezzanine and other subordinated loans, including those arising under bankruptcy, fraudulent conveyance, equitable subordination, environmental and other laws and regulations, and risks and costs associated with debt servicing and taking foreclosure actions associated with the loans.

Additionally, because loans are not ordinarily registered with the SEC or any state securities commission or listed on any securities exchange, there is usually less publicly available information about such instruments. In addition, loans may not be considered "securities" for purposes of the anti-fraud provisions under the federal securities laws and, as a result, as a purchaser of these instruments, the Fund may not be entitled to the anti-fraud protections of the federal securities laws. In the course of investing in such instruments, the Fund may come into possession of material nonpublic information and, because of prohibitions on trading in securities of issuers while in possession of such information, the Fund may be unable to enter into a transaction in a publicly-traded security of that issuer when it would otherwise be advantageous for the Fund to do so. Alternatively, the Fund may choose not to receive material nonpublic information about an issuer of such loans, with the result that the Fund may have less information about such issuers than other investors who transact in such assets.

The types of loans and related investments in which the Fund may invest include, among others, senior loans, subordinated loans (including second lien loans, B-Notes and mezzanine loans), whole loans, commercial real estate and other commercial loans and structured loans. The Fund may acquire direct interests in loans through primary loan distributions and/or in private transactions. In the case of subordinated loans, there may be significant indebtedness ranking ahead of the borrower's obligation to the holder of such a loan, including in the event of the borrower's insolvency. Mezzanine loans are typically secured by a pledge of an equity interest in the mortgage borrower that owns the real estate rather than an interest in a mortgage.

Investments in loans may include unfunded loan commitments, which are contractual obligations for future funding. Unfunded loan commitments may include revolving credit facilities, which may obligate the Fund to supply additional cash to the borrower on demand. Unfunded loan commitments represent a future obligation in full, even though a percentage of the committed amount may not be utilized by the borrower. When investing in a loan participation, the Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the agent selling the loan agreement and only upon receipt of payments by the agent from the borrower. Because investing in unfunded loan commitments creates a future obligation for the Fund to provide funding to a borrower upon demand in exchange for a fee, the Fund will segregate or earmark liquid assets with the Fund's custodian in amounts sufficient to satisfy any such future obligations. The Fund may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a loan. In certain circumstances, the Fund may receive a penalty fee upon the prepayment of a loan by a borrower. Fees earned or paid are recorded as a component of interest income or interest expense, respectively, on the Consolidated Statement of Operations. Unfunded loan commitments, if any, are reflected as a liability on the Consolidated Statement of Assets and Liabilities.

Master Limited Partnerships ("MLPs") are generally publicly traded entities that are organized as limited partnerships or limited liability companies and are treated as partnerships under the Internal Revenue Code. Currently, most MLPs operate in the energy and/or natural resources sectors. The only asset of an MLP is most commonly the ownership of the limited liability company or limited partnership known as the operating entity, which in turn owns subsidiaries and operating assets. The ownership of an MLP is split between the public and a sponsor. Interests in MLPs ("units") are often traded on securities exchanges like shares of corporate stock. An MLP consists of a general partner and limited partners (or in the case of MLPs organized as limited liability companies, a managing member and members). The general partner or managing member typically controls the operations and management of the MLP and has an ownership stake in the MLP. The limited partners or members, through their ownership of limited partner or member interests, provide capital to the entity, and are intended to receive cash distributions and to have no role in the operation and management of the entity. MLP cash distributions are not guaranteed and depend on each partnership's or limited liability company's ability to generate adequate cash flow. The partnership or operating agreements of MLPs determine how cash distributions will be made to general partners and limited partners or to managing members and members, as applicable.

Perpetual Bonds are fixed income securities with no maturity date but pay a coupon in perpetuity (with no specified ending or maturity date). Unlike typical fixed income securities, there is no obligation for perpetual bonds to repay principal. The coupon payments, however, are mandatory. While perpetual bonds have no maturity date, they may have a callable date in which the perpetuity

December 31, 2022

is eliminated and the issuer may return the principal received on the specified call date. Additionally, a perpetual bond may have additional features, such as interest rate increases at periodic dates or an increase as of a predetermined point in the future.

Real Estate Investment Trusts ("REITs") are pooled investment vehicles that own, and typically operate, income-producing real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not taxed on the income distributed to shareholders. Distributions received from REITs may be characterized as income, capital gain or a return of capital. A return of capital is recorded by the Fund as a reduction to the cost basis of its investment in the REIT. REITs are subject to management fees and other expenses, and so the Fund that invests in REITs will bear its proportionate share of the costs of the REITs' operations.

Restricted Investments are subject to legal or contractual restrictions on resale and may generally be sold privately, but may be required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted investments may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Restricted investments held by the Fund as of December 31, 2022, as applicable, are disclosed in the Notes to Consolidated Schedule of Investments.

Securities Issued by U.S. Government Agencies or Government-Sponsored Enterprises are obligations of and, in certain cases, guaranteed by, the U.S. Government, its agencies or instrumentalities. Some U.S. Government securities, such as Treasury bills, notes and bonds, and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Government; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Department of the Treasury (the "U.S. Treasury"); and others, such as those of the Federal National Mortgage Association ("FNMA" or "Fannie Mae"), are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations. U.S. Government securities may include zero coupon securities which do not distribute interest on a current basis and tend to be subject to a greater risk than interest-paying securities of similar maturities.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include FNMA and the Federal Home Loan Mortgage Corporation ("FHLMC" or "Freddie Mac"). FNMA is a government-sponsored corporation. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government. FHLMC issues Participation Certificates ("PCs"), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government. Instead, they are supported only by the discretionary authority of the U.S. Government to purchase the agency's obligations.

Warrants are securities that are usually issued together with a debt security or preferred security and that give the holder the right to buy a proportionate amount of common stock at a specified price. Warrants normally have a life that is measured in years and entitle the holder to buy common stock of a company at a price that is usually higher than the market price at the time the warrant is issued. Warrants may entail greater risks than certain other types of investments. Generally, warrants do not carry the right to receive dividends or exercise voting rights with respect to the underlying securities, and they do not represent any rights in the assets of the issuer. In addition, their value does not necessarily change with the value of the underlying securities, and they cease to have value if they are not exercised on or before their expiration date. If the market price of the underlying stock does not exceed the exercise price during the life of the warrant, the warrant will expire worthless. Warrants may increase the potential profit or loss to be realized from the investment as compared with investing the same amount in the underlying securities. Similarly, the percentage increase or decrease in the value of an equity security warrant may be greater than the percentage increase or decrease in the value of the underlying common stock. Warrants may relate to the purchase of equity or debt securities. Debt obligations with warrants attached to purchase equity securities have many characteristics of convertible securities and their prices may, to some degree, reflect the performance of the underlying stock. Debt obligations also may be issued with warrants attached to purchase additional debt securities at the same coupon rate. A decline in interest rates would permit the Fund to sell such warrants at a profit. If interest rates rise, these warrants would generally expire with no value.

5. BORROWINGS AND OTHER FINANCING TRANSACTIONS

The Fund may enter into the borrowings and other financing transactions described below to the extent permitted by the Fund's investment policies.

The following disclosures contain information on the Fund's ability to lend or borrow cash or securities to the extent permitted under the Act, which may be viewed as borrowing or financing transactions by the Fund. The location of these instruments in the Fund's financial statements is described below.

(a) Repurchase Agreements Under the terms of a typical repurchase agreement, the Fund purchases an underlying debt obligation (collateral) subject to an obligation of the seller to repurchase, and the Fund to resell, the obligation at an agreed-upon price and time. In an open maturity repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by the Fund or counterparty at any time. The underlying securities for all repurchase agreements are held by the Fund's custodian or designated subcustodians under tri-party repurchase agreements and in certain instances will remain in custody with the counterparty. The market value of the collateral must be equal to or exceed the total amount of the repurchase obligations, including interest. Repurchase agreements, if any, including accrued interest, are included on the Consolidated Statement of Assets and Liabilities. Interest earned is recorded as a component of interest income on the Consolidated Statement of Operations. In periods of increased demand for collateral, the Fund may pay a fee for the receipt of collateral, which may result in interest expense to the Fund.

(b) Reverse Repurchase Agreements In a reverse repurchase agreement, the Fund delivers a security in exchange for cash to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed upon price and

date. In an open maturity reverse repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by the Fund or counterparty at any time. The Fund is entitled to receive principal and interest payments, if any, made on the security delivered to the counterparty during the term of the agreement. Cash received in exchange for securities delivered plus accrued interest payments to be made by the Fund to counterparties are reflected as a liability on the Consolidated Statement of Assets and Liabilities. Interest payments made by the Fund to counterparties are recorded as a component of interest expense on the Consolidated Statement of Operations. In periods of increased demand for the security, the Fund may receive a fee for use of the security by the counterparty, which may result in interest income to the Fund. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities to be repurchased may decline below the repurchase price.

(c) Sale-Buybacks A sale-buyback financing transaction consists of a sale of a security by the Fund to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed-upon price and date. The Fund is not entitled to receive principal and interest payments, if any, made on the security sold to the counterparty during the term of the agreement. The agreed-upon proceeds for securities to be repurchased by the Fund are reflected as a liability on the Consolidated Statement of Assets and Liabilities. The Fund will recognize net income represented by the price differential between the price received for the transferred security and the agreed-upon repurchase price. This is commonly referred to as the 'price drop'. A price drop consists of (i) the foregone interest and inflationary income adjustments, if any, the Fund would have otherwise received had the security not been sold and (ii) the negotiated financing terms between the Fund and counterparty. Foregone interest and inflationary income adjustments, if any, are recorded as components of interest income on the Consolidated Statement of Operations. Interest payments based upon negotiated financing terms made by the Fund to counterparties are recorded as a component of interest expense on the Consolidated Statement of Operations. In periods of increased demand for the security, the Fund may receive a fee for use of the security by the counterparty, which may result in interest income to the Fund. Sale-buybacks involve leverage risk and also the risk that the market value of the securities to be repurchased may decline below the repurchase price.

6. FINANCIAL DERIVATIVE INSTRUMENTS

The Fund may enter into the financial derivative instruments described below to the extent permitted by the Fund's investment policies.

The following disclosures contain information on how and why the Fund uses financial derivative instruments, and how financial derivative instruments affect the Fund's financial position, results of operations and cash flows. The location and fair value amounts of these instruments on the Consolidated Statement of Assets and Liabilities and the net realized gain (loss) and net change in unrealized appreciation (depreciation) on the Consolidated Statement of Operations, each categorized by type of financial derivative contract and related risk exposure, are included in a table in the Notes to Consolidated Schedule of Investments. The financial derivative instruments outstanding as of period end and the amounts of net realized gain (loss) and net change in

---

| | | |
|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **55** |

---

------

unrealized appreciation (depreciation) on financial derivative instruments during the period, as disclosed in the Notes to Consolidated Schedule of Investments, serve as indicators of the volume of financial derivative activity for the Fund.

The Fund is subject to regulation as a commodity pool under the Commodity Exchange Act by the Commodity Futures Trading Commission (the "CFTC"). The Manager has registered with the CFTC as a Commodity Pool Operator and a Commodity Trading Adviser with respect to the Fund, and is a member of the National Futures Association. As a result, additional CFTC mandated disclosure, reporting and recordkeeping obligations apply to the Fund.

(a) Forward Foreign Currency Contracts may be engaged, in connection with settling planned purchases or sales of securities, to hedge the currency exposure associated with some or all of the Fund's securities or as part of an investment strategy. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date. The market value of a forward foreign currency contract fluctuates with changes in foreign currency exchange rates. Forward foreign currency contracts are marked to market daily, and the change in value is recorded by the Fund as an unrealized gain (loss). Realized gains (losses) are equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed and are recorded upon delivery or receipt of the currency. These contracts may involve market risk in excess of the unrealized gain (loss) reflected on the Consolidated Statement of Assets and Liabilities. In addition, the Fund could be exposed to risk if the counterparties are unable to meet the terms of the contracts or if the value of the currency changes unfavorably to the U.S. dollar. To mitigate such risk, cash or securities may be exchanged as collateral pursuant to the terms of the underlying contracts.

(b) Futures Contracts are agreements to buy or sell a security or other asset for a set price on a future date and are traded on an exchange. The Fund may use futures contracts to manage its exposure to the securities markets or to movements in interest rates and currency values. The primary risks associated with the use of futures contracts are the imperfect correlation between the change in market value of the securities held by the Fund and the prices of futures contracts and the possibility of an illiquid market. Futures contracts are valued based upon their quoted daily settlement prices. Upon entering into a futures contract, the Fund is required to deposit with its futures broker an amount of cash, U.S. Government and Agency Obligations, or select sovereign debt, in accordance with the initial margin requirements of the broker or exchange. Futures contracts are marked to market daily and based on such movements in the price of the contracts, an appropriate payable or receivable for the change in value may be posted or collected by the Fund ("Futures Variation Margin"). Futures Variation Margins, if any, are disclosed within centrally cleared financial derivative instruments on the Consolidated Statement of Assets and Liabilities. Gains (losses) are recognized but not considered realized until the contracts expire or close. Futures contracts involve, to varying degrees, risk of loss in excess of the Futures Variation Margin included within exchange traded or centrally cleared financial derivative instruments on the Consolidated Statement of Assets and Liabilities.

(c) Options Contracts may be written or purchased to enhance returns or to hedge an existing position or future investment. The Fund may write call and put options on securities and financial derivative instruments it owns or in which it may invest. Writing call options tends to decrease the Fund's exposure to underlying instrument. When the Fund writes a call or put, an amount equal to

---

(Unaudited)

December 31, 2022

the premium received is recorded and subsequently marked to market to reflect the current value of the option written. These amounts are included on the Consolidated Statement of Assets and Liabilities. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying futures, swap, security or currency transaction to determine the realized gain (loss). Certain options may be written with premiums to be determined on a future date. The premiums for these options are based upon implied volatility parameters at specified terms. The Fund as a writer of an option has no control over whether the underlying instrument may be sold ("call") or purchased ("put") and as a result bears the market risk of an unfavorable change in the price of the instrument underlying the written option. There is the risk the Fund may not be able to enter into a closing transaction because of an illiquid market.

Purchasing call options tends to increase the Fund's exposure to the underlying instrument. Purchasing put options tends to decrease the Fund's exposure to the underlying instrument. The Fund pays a premium which is included as an asset on the Consolidated Statement of Assets and Liabilities and subsequently marked to market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. Certain options may be purchased with premiums to be determined on a future date. The premiums for these options are based upon implied volatility parameters at specified terms. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain (loss) when the underlying transaction is executed.

Commodity Options are options on commodity futures contracts ("Commodity Option"). The underlying instrument for the Commodity Option is not the commodity itself, but rather a futures contract for that commodity. The exercise of a Commodity Option will not include physical delivery of the underlying commodity but will result in a cash transfer for the amount of the difference between the current market value of the underlying futures contract and the strike price. For an option that is in-the-money, the Fund will normally offset its position rather than exercise the option to retain any remaining time value.

Options on Indices ("Index Option") use a specified index as the underlying instrument for the option contract. The exercise for an Index Option will not include physical delivery of the underlying index but will result in a cash transfer of the amount of the difference between the settlement price of the underlying index and the strike price.

(d) Swap Agreements are bilaterally negotiated agreements between the Fund and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. Swap agreements may be privately negotiated in the over the counter market ("OTC swaps") or may be cleared through a third party, known as a central counterparty or derivatives clearing organization ("Centrally Cleared Swaps"). The Fund may enter into asset, credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements to manage its exposure to credit, currency, interest rate, commodity, equity and inflation risk. In connection with these agreements, securities or cash may be identified as collateral or margin in

---

| | | |
|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **57** |

---

------

accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Centrally Cleared Swaps are marked to market daily based upon valuations as determined from the underlying contract or in accordance with the requirements of the central counterparty or derivatives clearing organization. Changes in market value, if any, are reflected as a component of net change in unrealized appreciation (depreciation) on the Consolidated Statement of Operations. Daily changes in valuation of centrally cleared swaps, if any, are disclosed within centrally cleared financial derivative instruments on the Consolidated Statement of Assets and Liabilities. Centrally Cleared and OTC swap payments received or paid at the beginning of the measurement period are included on the Consolidated Statement of Assets and Liabilities and represent premiums paid or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). Upfront premiums received (paid) are initially recorded as liabilities (assets) and subsequently marked to market to reflect the current value of the swap. These upfront premiums are recorded as realized gain (loss) on the Consolidated Statement of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain (loss) on the Consolidated Statement of Operations. Net periodic payments received or paid by the Fund are included as part of realized gain (loss) on the Consolidated Statement of Operations.

For purposes of the Fund's investment policy adopted pursuant to Rule 35d-1 under the Act, the Fund will account for derivative instruments at market value. For purposes of applying the Fund's other investment policies and restrictions, swap agreements, like other derivative instruments, may be valued by the Fund at market value, notional value or full exposure value. In the case of a credit default swap, in applying certain of the Fund's investment policies and restrictions, the Fund will value the credit default swap at its notional value or its full exposure value (i.e., the sum of the notional amount for the contract plus the market value), but may value the credit default swap at market value for purposes of applying certain of the Fund's other investment policies and restrictions. For example, the Fund may value credit default swaps at full exposure value for purposes of the Fund's credit quality guidelines (if any) because such value in general better reflects the Fund's actual economic exposure during the term of the credit default swap agreement. As a result, the Fund may, at times, have notional exposure to an asset class (before netting) that is greater or lesser than the stated limit or restriction noted in the Fund's prospectus. In this context, both the notional amount and the market value may be positive or negative depending on whether the Fund is selling or buying protection through the credit default swap. The manner in which certain securities or other instruments are valued by the Fund for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

Entering into swap agreements involves, to varying degrees, elements of interest, credit, market and documentation risk in excess of the amounts recognized on the Consolidated Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates or the values of the asset upon which the swap is based.

The Fund's maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract's remaining life, to the extent that amount is positive. The risk may be mitigated by having a master netting arrangement between the Fund and the counterparty and by the posting of collateral to the Fund to cover the Fund's exposure to the counterparty.

To the extent the Fund has a policy to limit the net amount owed to or to be received from a single counterparty under existing swap agreements, such limitation only applies to counterparties to OTC swaps and does not apply to centrally cleared swaps where the counterparty is a central counterparty or derivatives clearing organization.

Interest Rate Swap Agreements may be entered into to help hedge against interest rate risk exposure and to maintain the Fund's ability to generate income at prevailing market rates. The value of the fixed rate bonds that the Fund holds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swap agreements. Interest rate swap agreements involve the exchange by the Fund with another party for their respective commitment to pay or receive interest on the notional amount of principal. Certain forms of interest rate swap agreements may include: (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or "cap," (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or "floor," (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels, (iv) callable interest rate swaps, under which the buyer pays an upfront fee in consideration for the right to early terminate the swap transaction in whole, at zero cost and at a predetermined date and time prior to the maturity date, (v) spreadlocks, which allow the interest rate swap users to lock in the forward differential (or spread) between the interest rate swap rate and a specified benchmark, or (vi) basis swaps, under which two parties can exchange variable interest rates based on different segments of money markets.

Total Return Swap Agreements are entered into to gain or mitigate exposure to the underlying reference asset. Total return swap agreements involve commitments where single or multiple cash flows are exchanged based on the price of an underlying reference asset and on a fixed or variable interest rate. Total return swap agreements may involve commitments to pay interest in exchange for a market-linked return. One counterparty pays out the total return of a specific underlying reference asset, which may include a single security, a basket of securities, or an index, and in return receives a fixed or variable rate. At the maturity date, a net cash flow is exchanged where the total return is equivalent to the return of the underlying reference asset less a financing rate, if any. As a receiver, the Fund would receive payments based on any net positive total return and would owe payments in the event of a net negative total return. As the payer, the Fund would owe payments on any net positive total return, and would receive payments in the event of a net negative total return.

7. PRINCIPAL AND OTHER RISKS

(a) Principal Risk

In the normal course of business, the Fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to such things as changes in the market (market

---

|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **59** |

risk) or failure or inability of the other party to a transaction to perform (credit and counterparty risk). See below for a detailed description of select principal risks. For further information regarding the principal risks the Fund may be subject to, please see the Principal Risks of the Fund section of the Fund's annual report dated June 30, 2022.

Asset Allocation Risk is the risk that the Fund could lose money as a result of less than optimal or poor asset allocation decisions. The Fund could miss attractive investment opportunities by underweighting markets that subsequently experience significant returns and could lose value by overweighting markets that subsequently experience significant declines.

Call Risk is the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer's credit quality). If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk is the risk that an investment in a CLO, CBO or other CDO depends largely on the type of the collateral securities and the class/tranche of the instrument in which the Fund invests. In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs, CBOs and CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the risk that the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

Confidential Information Access Risk is the risk that, in managing the Fund (and other PIMCO clients), PIMCO may from time to time have the opportunity to receive material, non-public information ("Confidential Information") about the issuers of certain investments, including, without limitation, senior floating rate loans, other loans and related investments being considered for acquisition by the Fund or held in the Fund's portfolio. If PIMCO intentionally or unintentionally comes into possession of Confidential Information, it may be unable, potentially for a substantial period of time, to purchase or sell investments to which such Confidential Information relates.

Contingent Convertible Securities Risk is the risk of investing in contingent convertible securities, including the risk that interest payments will be cancelled by the issuer or a regulatory authority, the risk of ranking junior to other creditors in the event of a liquidation or other bankruptcy-related event as a result of holding subordinated debt, the risk of the Fund's investment becoming further subordinated as a result of conversion from debt to equity, the risk that the principal amount due can be written down to a lesser amount, and the general risks applicable to fixed income investments, including interest rate risk, credit risk, market risk and liquidity risk, any of which could result in losses to the Fund.

Convertible Securities Risk is the risk that the market values of convertible securities may decline as interest rates increase and, conversely, may increase as interest rates decline. A convertible security's

market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security's "conversion price." The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities may be paid before the company's common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer's convertible securities generally entail less risk than its common stock but more risk than its debt obligations. Convertible securities are often rated below investment grade or not rated.

Corporate Debt Securities Risk is the risk that the market value of a corporate debt security may be affected by factors directly relating to the issuer and that the issuers of corporate debt securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. The market value of corporate debt securities generally may be expected to rise and fall inversely with interest rates. In addition, certain corporate debt securities may be highly customized and as a result may be subject to, among others, liquidity and valuation/pricing transparency risks.

Counterparty Risk is the risk that the Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund or held by special purpose or structured vehicles in which the Fund invests. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy, or other analogous proceeding.

Credit Default Swaps Risk is the risk of investing in credit default swaps, including illiquidity risk, counterparty risk, leverage risk and credit risk. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein since if an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation. In addition, selling credit default swaps may not be profitable for the Fund if no secondary market exists or the Fund is otherwise unable to close out these transactions at advantageous times.

Credit Risk is the risk that the Fund could lose money if the issuer or guarantor of a fixed-income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations. Measures such as average credit quality may not accurately reflect the true credit risk of the Fund. This is especially the case if the Fund consists of securities with widely varying credit ratings.

Currency Risk is the risk that investments denominated in foreign (non-U.S.) currencies or that trade in and receive revenues in, foreign (non-U.S.) currencies, or derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies may decline in value, due to the risk that those

| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **61** |

---

------

currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Cyber Security Risk is the risk that, as the use of technology has become more prevalent in the course of business, the Fund has become potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events that may, among other things, cause the Fund to lose proprietary information, suffer data corruption and/or destruction or lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security failures or breaches may result in financial losses to the Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with the Fund's ability to calculate its net asset value, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

Debt Securities Risk is the risk that prices of bonds and other fixed income securities will generally increase as interest rates fall and decrease as interest rates rise. Income from the Fund's portfolio may decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio's current earnings rate. The value of most bond funds and fixed income securities are impacted by changes in interest rates. Bonds and bond funds with longer durations tend to be more sensitive and more volatile than securities with shorter durations; bond prices generally fall as interest rates rise.

Derivatives Risk is the risk of investing in derivative instruments (such as futures, swaps and structured securities), including leverage, liquidity, interest rate, market, credit, management, counterparty, operational and legal risks and valuation complexity. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. The Fund's use of derivatives may result in losses to the Fund, a reduction in the Fund's returns and/or increased volatility. Over-the-counter ("OTC") derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for OTC derivatives. The primary credit risk on derivatives that are exchange-traded or traded through a central clearing counterparty resides with the Fund's clearing broker, or the clearinghouse itself.

Distressed and Defaulted Securities Risk is the risk of investing in the securities of financially distressed issuers, including the risk of default. These securities may fluctuate more in price and are typically less liquid. The Fund also will be subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially distressed issuers will eventually be satisfied.

Distribution Rate Risk is the risk that, to the extent the Fund seeks to maintain a level distribution rate, the Fund's distribution rate may be affected by numerous factors, including but not limited to

---

| | |
|:---|:---|
| **62** | **PIMCO CLOSED-END FUNDS** |

---

(Unaudited)

December 31, 2022

changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. For instance, during periods of low or declining interest rates, the Fund's distributable income and dividend levels may decline for many reasons. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund's distribution rate or that the rate will be sustainable in the future.

Emerging Markets Risk is the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk.

Energy Sector Risk is the risk that applies to the Fund's investments in MLPs and other companies which operate natural gas, natural gas liquids, crude oil, refined products, coal or other facilities within the energy sector. The Fund's performance will be susceptible to fluctuations in commodity prices, changes in the supply of or demand for energy commodities, an inability to acquire additional energy deposits sufficient to replace the natural depletion of existing reserves, environmental and safety regulations, seasonal and extreme weather, catastrophic events or accidents, acquisition costs and erroneous assumptions regarding new acquisitions and the cyclical fluctuation and intense price competition inherent to the energy industry. Additionally, MLPs and other entities operating in the energy sector are subject to industry-specific risks related to infrastructure, which includes transportation via pipeline, the gathering, processing and midstream storage of resources, variations in upstream and downstream demand, and the effects of land, weather and unforeseen events on oil, oilfields, coal stockpiles, power infrastructure and marine transportation.

Equity Securities and Related Market Risk is the risk that the value of equity securities, such as common stocks and preferred securities, may decline due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity securities generally have greater price volatility than fixed income securities.

Focused Investment Risk is the risk that, to the extent that the Fund focuses its investments in a particular industry, country or geographic region, the NAV of its common shares will be more susceptible to events or factors affecting companies in that industry, country or geographic region.

Foreign (Non-U.S.) Government Securities Risk is the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion.

Foreign (Non-U.S.) Investment Risk is the risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to smaller markets, differing reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, political changes, diplomatic developments or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers.

High Yield Securities Risk is the risk that high yield securities and unrated securities of similar credit quality (commonly known as "junk bonds") are subject to greater levels of credit, call and liquidity

---

|:---|:---|:---|
| **SEMIANNUAL REPORT** | DECEMBER 31, 2022 | **63** |

---

------

risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments and may be more volatile than higher-rated securities of similar maturity.

Industry Specific Risks are the risks that MLPs and other entities operating in a specific sector that are specific to the industry within that sector they serve.

Inflation/Deflation Risk is the risk that the value of assets or income from the Fund's investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund's portfolio could decline. Deflation Risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund's portfolio and common shares.

Inflation-Indexed Security Risk is the risk that inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including TIPS, tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity.

Interest Rate Risk is the risk that fixed income securities and other instruments in the Fund's portfolio will decline in value because of an increase in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a short average portfolio duration.

Issuer Risk is the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services.

Leverage Risk is the risk that certain transactions of the Fund, such as reverse repurchase agreements, dollar rolls and/or borrowings (as well as from any future issuance of preferred shares), delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss.

Limited Term Risk is the risk that unless, the limited term provision of the Fund's Declaration of Trust is amended by shareholders in accordance with the Declaration of Trust, or unless the Fund completes an Eligible Tender Offer and converts to perpetual existence, the Fund will terminate on or about a date specified in the Fund's Prospectus.

Liquidity Risk is the risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell illiquid investments at an advantageous time or price or possibly require

the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations, which could prevent the Fund from taking advantage of other investment opportunities. Additionally, the market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer.

Loans and Other Indebtedness; Loan Participations and Assignments Risk is the risk that scheduled interest or principal payments will not be made in a timely manner or at all, either of which may adversely affect the values of a loan. Additionally, there is a risk that the collateral underlying a loan may be unavailable or insufficient to satisfy a borrower's obligation, and the Fund could become part owner of any collateral if a loan is foreclosed, subjecting the Fund to costs associated with owning and disposing of the collateral.

In the event of the insolvency of the lender selling a participation, there is a risk that the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

There is the risk that the Fund may have difficulty disposing of loans and loan participations due to the lack of a liquid secondary market for loans and loan participations.

To the extent the Fund acquires loans, including bank loans, the Fund may be subject to greater levels of credit risk, call risk, settlement risk and liquidity risk than funds that do not acquire such instruments.

Management Risk is the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio manager in connection with managing the Fund and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Fund will be achieved.

Market Discount Risk is the risk that the price of the Fund's common shares of beneficial interest will fluctuate with market conditions and other factors. Shares of closed-end management investment companies frequently trade at a discount from their net asset value.

Market Disruptions Risk is the risk of investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets and cause the Fund to lose value. These events can also impair the technology and other operational systems upon which the Fund's service providers, including PIMCO as the Fund's investment adviser, rely, and could otherwise disrupt the Fund's service providers' ability to fulfill their obligations to the Fund.

Market Risk is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably due to factors affecting securities markets generally or particular industries.

Mortgage-Related and Other Asset-Backed Securities Risk is the risk of investing in mortgage- related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk.

Municipal Bond Risk is the risk that the Fund may be affected significantly by the economic, regulatory or political developments affecting the ability of issuers of debt securities whose interest is, in the opinion of bond counsel for the issuer at the time of issuance, exempt from federal income tax to pay interest or repay principal.

Non-Diversification Risk is the risk of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. Funds that are "non-diversified" may invest a greater percentage of their assets in the securities of a single issuer (such as bonds issued by a particular state) than funds that are "diversified."

Operational Risk is the risk arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Other Investment Companies Risk is the risk that Common Shareholders may be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, these other investment companies may utilize leverage, in which case an investment would subject the Fund to additional risks associated with leverage.

Portfolio Turnover Risk is the risk that a high portfolio turnover will result in greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. Such sales may result in realization of taxable capital gains (including short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates when distributed net of short-term capital losses and net long-term capital losses) and may adversely affect the Fund's after-tax returns.

Potential Conflicts of Interest Risk — Allocation of Investment Opportunities is the risk that PIMCO's interests or the interests of its clients may conflict with those of the Funds and the results of the Fund's investment activities may differ from those of the Fund's affiliates, or another account managed by the Fund's affiliates, and it is possible that the Fund could sustain losses during periods in which one or more of the Fund's affiliates and/or other accounts managed by PIMCO or its affiliates, including proprietary accounts, achieve profits on their trading.

Preferred Securities Risk is the risk that certain preferred securities contain provisions that allow an issuer under certain conditions to skip or defer distributions which may require the Fund to include the amount of the deferred distribution in its taxable income for tax purposes although it does not currently receive such amount in cash. Additionally, preferred securities are subordinated to bonds

December 31, 2022

and other debt securities in an issuer's capital structure in terms of priority for corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt securities. Preferred securities may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities, such as common stocks, corporate debt securities and U.S. Government securities.

Private Placements Risk is the risk that securities received in a private placement may be subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so, or at the most favorable time or price. Private placements may also raise valuation risks.

Regulatory Changes Risk is the risk that is associated with the fact that financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/or intervention may change the way the Fund is regulated, affect the expenses incurred directly by the Fund and the value of its investments, and limit and /or preclude the Fund's ability to achieve its investment objectives. Government regulation may change frequently and may have significant adverse consequences. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and the Investment Manager will continue to be eligible for such exemptions.

Regulatory Risk — Commodity Pool Operator is the risk associated with the CFTC's adopted regulations that subject registered investment companies and their investment advisers to regulation by the CFTC if the registered investment company invests more than a prescribed level of its liquidation value in futures, options on futures or commodities, swaps, or other financial instruments regulated under the Commodity Exchange Act ("CEA") and the rules thereunder ("commodity interests"), or if the Fund markets itself as providing investment exposure to such instruments. The Investment Manager is registered with the CFTC as a Commodity Pool Operator.

Regulatory Risk — LIBOR is the risk related to the anticipated discontinuation of the London Interbank Offered Rate ("LIBOR"). Certain instruments held by the Fund rely in some fashion upon LIBOR. Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation date, there remains uncertainty regarding the nature of any replacement rate, and any potential effects of the transition away from LIBOR on the Fund or on certain instruments in which the Fund invests can be difficult to ascertain. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR and may result in a reduction in the value of certain instruments held by the Fund.

Reinvestment Risk is the risk that income from the Fund's portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio's current earnings rate. The Fund also may choose to sell higher yielding

|:---|:---|:---|

---

------

portfolio securities and to purchase lower yielding securities to achieve greater portfolio diversification, because the portfolio managers believe the current holdings are overvalued or for other investment-related reasons.

Repurchase Agreements Risk is the risk that, if the party agreeing to repurchase a security should default, the Fund will seek to sell the securities which it holds, which could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price.

Restricted Securities Risk is the risk that the Fund's investment in securities that have not been registered for public sale, but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act, may be relatively less liquid than registered securities traded on established securities markets.

Risks of Equity Securities of MLPS, Risks of Debt Securities of MLPS, and Risks of MLP General Partner and Managing Member Interests is the risk that investments in equity and debt securities of MLPs and/or their affiliates are subject to risks in addition to those risks associated with investments in all equity and debt securities. Holders of MLP units have more limited rights for voting and control than shareholders of common stock in a corporation, additional tax risks and additional potential conflicts of interest among unit holders and partners. MLP subordinated units generally entail greater risk than MLP common units as a result of more limited distribution rights. Additionally, distributions by certain MLPs may be affected by the failure of an affiliated party to satisfy its obligations to an MLP or by an MLP's loss of customers or suppliers. The Fund's investment in MLPs or other entities that hold a general partner or managing member interest and IDRs in MLPs may be subject to additional liability greater than the investment amount and may have higher distribution prospects which would decline at a greater rate than the decline rate in and MLP's distributions or be eliminated if the MLP unit holders choose to remove the general partner or managing member.

Risks of ETNs is the risk that the value of exchange-traded notes ("ETNs") may be influenced by time to maturity, level of supply and demand for the ETN, volatility, and lack of liquidity in underlying markets, changes in the applicable interest rates and underlying reference asset values, changes in the issuer's credit rating, and economic, legal, political, or geographic events that may affect the referenced index.

Securities Lending Risk is the risk that, when the Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned and lose rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund may pay lending fees to a party, which may be an affiliate of the Fund, arranging the loan.

Senior Debt Risk is the risk that the Fund may be subject to greater levels of credit risk than funds that do not invest in below investment grade senior debt. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior debt. Restrictions on transfers in loan agreements, a lack of publicly available information and other factors may, in certain instances, make senior debt more difficult to sell at an advantageous time or price than other types of securities or instruments.

Short Exposure Risk is the risk of entering into short sales, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale will not fulfill its contractual obligations, causing a loss to the Fund.

Sovereign Debt Risk is the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion.

Structured Investments Risk is the risk that the Fund's investment in structured products, including, structured notes, credit-linked notes and other types of structured products bear the risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. Structured products generally entail risks associated with derivative instruments.

Subprime Risk is the risk that loans, and debt instruments collateralized by loans (including Alt Lending ABS), acquired by the Fund may be subprime in quality, or may become subprime in quality. Although there is no specific legal or market definition of "subprime," subprime loans are generally understood to refer to loans made to borrowers that display poor credit histories and other characteristics that correlate with a higher default risk. Accordingly, subprime loans, and debt instruments secured by such loans, have speculative characteristics and are subject to heightened risks, including the risk of nonpayment of interest or repayment of principal, and the risks associated with investments in high yield securities. In addition, these instruments could be subject to increased regulatory scrutiny. The Fund is not restricted by any particular borrower credit criteria when acquiring loans or debt instruments collateralized by loans.

Subsidiary Risk is the risk that, by investing in the Fund's subsidiaries, the Fund would be exposed to the risks associated with the subsidiary's investments. Fund subsidiaries are not registered under the Act and may not be subject to all the investor protections of the Act. There is no guarantee that the investment objective of a subsidiary will be achieved.

Synthetic Convertible Securities Risk is the risk that the values of synthetic convertible securities will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, (such as a debt security and a warrant or option to purchase another security), each with its own market value. Synthetic convertible securities are also subject to the risks associated with derivatives. In addition, if the value of the underlying common stock or the level of the index involved in the convertible element falls below the strike price of the warrant or option, the warrant or option may lose all value.

Tax Risk is the risk that if, in any year, the Fund were to fail to qualify for treatment as a regulated investment company under the Tax Code, and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at corporate rates and, when such income is distributed, shareholders would be subject to a further tax to the extent of the Fund's current or accumulated earnings and profits.

Total Return Swap Risk is the risk that total return swaps could result in losses if the underlying asset or reference does not perform as anticipated, that they add leverage to the Fund's portfolio and the risk that the counterparty might default on the contract. Total return swaps can have the potential for unlimited losses. Total return swaps are also subject to certain other risks applicable to derivatives transactions generally.

U.S. Government Securities Risk is the risk that the obligations supported by (i) the full faith and credit of the United States, (ii) the right of the issuer to borrow from the U.S. Treasury, (iii) the discretionary authority of the U.S. Government to purchase the agency's obligations (iv) or only by the credit of the agency, instrumentality or corporation will not be satisfied in full, or that such obligations will decrease in value or default.

Valuation Risk is the risk that fair value pricing used when market quotations are not readily available may not result in adjustments to the prices of securities or other assets, or that fair value pricing may not reflect actual market value. It is possible that the fair value determined in good faith for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Zero-Coupon Bond, Step-Ups and Payment-in-Kind Securities Risk is the risk presented by the market prices of zero-coupon, step ups and payment-in-kind securities generally being more volatile than the prices of securities that pay interest periodically and in cash and being likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. In addition, as these securities may not pay cash interest, the Fund's investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund's portfolio.

(b) Other Risks

In general, the Fund may be subject to additional risks, including, but not limited to, risks related to government regulation and intervention in financial markets, operational risks, risks associated with financial, economic and global market disruptions, and cyber security risks. Please see the Important Information section of this report for additional discussion of certain regulatory and market developments that may impact the Fund's performance.

8. MASTER NETTING ARRANGEMENTS

The Fund may be subject to various netting arrangements ("Master Agreements") with select counterparties. Master Agreements govern the terms of certain transactions, and are intended to reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that is intended to improve legal certainty. Each type of Master Agreement governs certain types of transactions. Different types of transactions may be traded out of different legal entities or affiliates of a particular organization, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow the Fund to close out and net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single Master Agreement with a counterparty. For financial reporting purposes the Consolidated Statement

---

|:---|:---|
| **70** | **PIMCO CLOSED-END FUNDS** |

---

(Unaudited)

December 31, 2022

of Assets and Liabilities generally present derivative assets and liabilities on a gross basis, which reflects the full risks and exposures prior to netting.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under most Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury Bills and U.S. dollar cash are generally the preferred forms of collateral, although other securities may be used depending on the terms outlined in the applicable Master Agreement. Securities and cash pledged as collateral are reflected as assets on the Consolidated Statement of Assets and Liabilities as either a component of Investments at value (securities) or Deposits with counterparty. Cash collateral received is not typically held in a segregated account and as such is reflected as a liability on the Consolidated Statement of Assets and Liabilities as Deposits from counterparty. The market value of any securities received as collateral is not reflected as a component of NAV. The Fund's overall exposure to counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement.

Master Repurchase Agreements and Global Master Repurchase Agreements (individually and collectively "Master Repo Agreements") govern repurchase, reverse repurchase, and certain sale-buyback transactions between the Fund and select counterparties. Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral. The market value of transactions under the Master Repo Agreement, collateral pledged or received, and the net exposure by counterparty as of period end are disclosed in the Notes to Consolidated Schedule of Investments.

Master Securities Forward Transaction Agreements ("Master Forward Agreements") govern certain forward settling transactions, such as TBA securities, delayed-delivery or certain sale-buyback transactions by and between the Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, transaction initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral. The market value of forward settling transactions, collateral pledged or received, and the net exposure by counterparty as of period end is disclosed in the Notes to Consolidated Schedule of Investments.

Customer Account Agreements and related addenda govern cleared derivatives transactions such as futures, options on futures, and cleared OTC derivatives. Such transactions require posting of initial margin as determined by each relevant clearing agency which is segregated in an account at a futures commission merchant ("FCM") registered with the CFTC. In the United States, counterparty risk may be reduced as creditors of an FCM cannot have a claim to Fund assets in the segregated account. Portability of exposure reduces risk to the Fund. Variation margin, which reflects changes in market value, is generally exchanged daily, but may not be netted between futures and cleared OTC derivatives unless the parties have agreed to a separate arrangement in respect of portfolio margining. The market value or accumulated unrealized appreciation (depreciation), initial margin posted, and any unsettled variation margin as of period end are disclosed in the Notes to Consolidated Schedule of Investments.

Prime Broker Arrangements may be entered into to facilitate execution and/or clearing of listed equity option transactions or short sales of equity securities between the Fund and selected counterparties. The arrangements provide guidelines surrounding the rights, obligations, and other events, including, but not limited to, margin, execution, and settlement. These agreements maintain provisions for, among other things, payments, maintenance of collateral, events of default, and termination. Margin and other assets delivered as collateral are typically in the possession of the prime broker and would offset any obligations due to the prime broker. The market values of listed options and securities sold short and related collateral are disclosed in the Notes to Consolidated Schedule of Investments.

International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes ("ISDA Master Agreements") govern bilateral OTC derivative transactions entered into by the Fund with select counterparties. ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral posting and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to terminate early could be material to the financial statements. The ISDA Master Agreement may contain additional provisions that add counterparty protection beyond coverage of existing daily exposure if the counterparty has a decline in credit quality below a predefined level or as required by regulation. Similarly, if required by regulation, the Fund may be required to post additional collateral beyond coverage of daily exposure. These amounts, if any, may (or if required by law, will) be segregated with a third-party custodian. To the extent the Fund is required by regulation to post additional collateral beyond coverage of daily exposure, it could potentially incur costs, including in procuring eligible assets to meet collateral requirements, associated with such posting. The market value of OTC financial derivative instruments, collateral received or pledged, and net exposure by counterparty as of period end are disclosed in the Notes to Consolidated Schedule of Investments.

9. FEES AND EXPENSES

(a) Management Fee Pursuant to the Investment Management Agreement with PIMCO (the "Agreement"), and subject to the supervision of the Board, PIMCO is responsible for providing the Fund investment guidance and policy direction in connection with the management of the Fund, including oral and written research, analysis, advice, and statistical and economic data and information. In addition, pursuant to the Agreement and subject to the general supervision of the Board, PIMCO, at its expense, provides or causes to be furnished most other supervisory and administrative services the Fund requires, including but not limited to, expenses of most third-party service providers (e.g., audit, custodial, legal, transfer agency, printing) and other expenses, such as those associated with insurance, proxy solicitations and mailings for shareholder meetings, NYSE listing and related fees, tax services, valuation services and other services the Fund requires for its daily operations.

Pursuant to the Agreement, PIMCO receives an annual management fee, payable monthly, at the annual rate of 1.35% of the Fund's average daily total managed assets (including assets attributable to any reverse repurchase agreements, dollar rolls, borrowings and preferred shares outstanding) minus accrued liabilities (other than liabilities representing reverse repurchase agreements, dollar rolls and borrowings).

(b) Fund Expenses The Fund bears other expenses, which may vary and affect the total level of expenses paid by shareholders, such as (i) salaries and other compensation or expenses, including travel expenses, of any of the Fund's executive officers and employees, if any, who are not officers, directors, shareholders, members, partners or employees of PIMCO or its subsidiaries or affiliates; (ii) taxes and governmental fees, if any, levied against the Fund; (iii) brokerage fees and commissions and other portfolio transaction expenses incurred by or for the Fund (including, without limitation, fees and expenses of outside legal counsel or third-party consultants retained in connection with reviewing, negotiating and structuring specialized loans and other investments made by the Fund, and any costs associated with originating loans, asset securitizations, alternative lending-related strategies and so-called "broken-deal costs" (e.g., fees, costs, expenses and liabilities, including, for example, due diligence-related fees, costs, expenses and liabilities, with respect to unconsummated investments)); (iv) expenses of the Fund's securities lending (if any), including any securities lending agent fees, as governed by a separate securities lending agreement; (v) costs, including interest expenses, of borrowing money or engaging in other types of leverage financing, including, without limitation, through the use by the Fund of reverse repurchase agreements, dollar rolls, bank borrowings, credit facilities and tender option bonds and; (vi) costs, including dividend and/or interest expenses and other costs (including, without limitation, offering and related legal costs, fees to brokers, fees to auction agents, fees to transfer agents, fees to ratings agencies and fees to auditors associated with satisfying ratings agency requirements for preferred shares or other securities issued by the Fund and other related requirements in the Fund's organizational documents) associated with the Fund's issuance, offering, redemption and maintenance of preferred shares, commercial paper or other instruments (such as the use of reverse repurchase agreements, dollar rolls, bank borrowings, credit facilities and tender option bonds) for the purpose of incurring leverage; (vii) fees and expenses of any underlying funds or other pooled vehicles in which the Fund invests; (viii) dividend and interest expenses on short positions taken by the Fund; (ix) fees and expenses, including travel expenses, and fees and expenses of legal counsel retained for their benefit, of Trustees who are not officers, employees, partners, shareholders or members of PIMCO or its subsidiaries or affiliates; (x) extraordinary expenses, including extraordinary legal expenses, as may arise, including, without limitation expenses incurred in connection with litigation, proceedings, other claims, and the legal obligations of the Fund to indemnify its Trustees, officers, employees, shareholders, distributors, and agents with respect thereto; (xi) fees and expenses, including legal, printing and mailing, solicitation and other fees and expenses associated with and incident to shareholder meetings and proxy solicitations involving contested elections of trustees, shareholder proposals or other non-routine matters that are not initiated or proposed by Fund management; (xii) organizational and offering expenses of the Fund; (xiii) expenses associated with tender offers and other share repurchases and redemptions; (xiv) fees and expenses associated with seeking, applying for and obtaining formal exemptive, no-action and/or other relief from the SEC in connection with the operation of a managed distribution plan; and (xv) expenses of the Fund that are capitalized in accordance with U.S. GAAP. Without limiting the generality or scope of the foregoing, it is understood that the Fund may bear such expenses either directly or indirectly through contracts or arrangements with PIMCO or an affiliated or unaffiliated third party.

Each of the Trustees of the Fund who is not an "interested person" under Section 2(a)(19) of the Act, (the "Independent Trustees") also serves as a trustee of a number of other closed-end funds for which PIMCO serves as investment manager (together with the Fund, the "PIMCO Closed-End

Funds"), as well as PIMCO California Flexible Municipal Income Fund, PIMCO Flexible Emerging Markets Income Fund, PIMCO Flexible Credit Income Fund and PIMCO Flexible Municipal Income Fund, each a closed end management investment company managed by PIMCO that is operated as an "interval fund", and PIMCO Managed Accounts Trust, an open-end management investment company with multiple series for which PIMCO serves as investment adviser and administrator.

The Fund pays no compensation directly to any Trustee or any other officer who is affiliated with the Manager, all of whom receive remuneration for their services to the Fund from the Manager or its affiliates.

(c) Acquired Fund Fees and Expenses The Cayman Subsidiary has entered into a separate contract with PIMCO for the management of the Cayman Subsidiary's portfolio pursuant to which the Cayman Subsidiary pays PIMCO a management fee at the annual rate of 0.69% of its average daily net assets. PIMCO has contractually agreed to waive the Fund's management fee in an amount equal to the management fee paid by the Cayman Subsidiary to PIMCO. This waiver may not be terminated by PIMCO and will remain in effect for as long as PIMCO's contract with the Subsidiary is in place. PIMCO may not seek reimbursement from the Fund with respect to the management fees waived. The waiver is reflected on the Consolidated Statement of Operations as a component of Waiver and/or Reimbursement by PIMCO. For the period ended December 31, 2022, the amount was $93,626. See Note 13, Basis for Consolidation in the Notes to Financial Statements for more information regarding the Cayman Subsidiary.

10. RELATED PARTY TRANSACTIONS

The Manager is a related party. Fees payable to this party are disclosed in Note 9, Fees and Expenses, and the accrued related party fee amounts are disclosed on the Consolidated Statement of Assets and Liabilities.

The Fund is permitted to purchase or sell securities from or to certain related affiliated funds under specified conditions outlined in procedures adopted by the Board. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that are, or could be, considered an affiliate, or an affiliate of an affiliate, by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with applicable SEC rules and interpretations under the Act. Further, as defined under the procedures, each transaction is effected at the current market price. Purchases and sales of securities pursuant to applicable SEC rules and interpretations under the Act for the period ended December 31, 2022, were as follows (amounts in thousands<sup>†</sup>):

|:---|:---|:---|
| **Purchases** | **Sales** | **Realized<br>Gain/(Loss)** |

11. GUARANTEES AND INDEMNIFICATIONS

Under the Fund's organizational documents, each Trustee and officer is indemnified, to the extent permitted by the Act, against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts that contain

(Unaudited)

December 31, 2022

a variety of indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts.

12. PURCHASES AND SALES OF SECURITIES

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as "portfolio turnover." The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objective(s), particularly during periods of volatile market movements. High portfolio turnover may involve correspondingly greater transaction costs, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities, which are borne by the Fund. Such sales may also result in realization of taxable capital gains, including short-term capital gains (which are generally taxed at ordinary income tax rates when distributed to shareholders). The transaction costs and tax effects associated with portfolio turnover may adversely affect the Fund's performance. The portfolio turnover rates are reported in the Financial Highlights.

Purchases and sales of securities (excluding short-term investments) for the period ended December 31, 2022, were as follows (amounts in thousands<sup>†</sup>):

13. BASIS FOR CONSOLIDATION

The Cayman Subsidiary, and NRGX SPV I LLC, a Delaware limited liability company, were formed as Subsidiaries acting as investment vehicles for the Fund in order to effect certain investments for the Fund consistent with the Fund's investment objectives and policies in effect from time to time. The Fund's investment portfolio has been consolidated and includes the portfolio holdings of the Fund and the Subsidiaries. Accordingly, the consolidated financial statements include the accounts of the Fund and the Subsidiaries. All inter-company transactions and balances have been eliminated. These structures were established so that certain investments could be held by separate legal entities from the Fund. See the table below for details regarding the structure, incorporation and relationship as of period end of the Subsidiaries.

14. REGULATORY AND LITIGATION MATTERS

The Fund is not named as a defendant in any material litigation or arbitration proceedings and is not aware of any material litigation or claim pending or threatened against it.

On May 17, 2022, Allianz Global Investors U.S. LLC ("AGI U.S.") pleaded guilty in connection with the proceeding United States of America v. Allianz Global Investors U.S. LLC. AGI U.S. is an indirect subsidiary of Allianz SE. The conduct resulting in the matter described above occurred entirely within AGI U.S. and did not involve PIMCO or the Distributor, or any personnel of PIMCO or the Distributor. Nevertheless, because of the disqualifying conduct of AGI U.S., their affiliate, PIMCO would have been disqualified from serving as the investment adviser, and the Distributor would have been disqualified from serving as the principal underwriter, to the Fund in the absence of SEC exemptive relief. PIMCO and the Distributor have received exemptive relief from the SEC to permit them to continue serving as investment adviser and principal underwriter for U.S.- registered investment companies, including the Fund.

The foregoing speaks only as of the date of this report.

15. FEDERAL INCOME TAX MATTERS

The Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code (the "Code") and distribute all of its taxable income and net realized gains, if applicable, to shareholders. Accordingly, no provision for Federal income taxes has been made. Due to the timing of when distributions are made by a Fund, the Fund may be subject to an excise tax of 4% of the amount by which 98% of the Fund's annual taxable income and 98.2% of net realized gains exceed the distributions from such taxable income and realized gains for the calendar year.

The Fund may be subject to local withholding taxes, including those imposed on realized capital gains. Any applicable foreign capital gains tax is accrued daily based upon net unrealized gains, and may be payable following the sale of any applicable investments.

In accordance with U.S. GAAP, the Manager has reviewed the Fund's tax positions for all open tax years. As of December 31, 2022, the Fund has recorded no liability for net unrecognized tax benefits relating to uncertain income tax positions it has taken or expects to take in future tax returns.

The Fund files U.S. federal, state, and local tax returns as required. The Fund's tax returns are subject to examination by relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

The Fund may gain exposure to the commodities markets through investments in swap agreements, futures, and options.

The Fund may also gain exposure indirectly to commodity markets by investing in the Subsidiary, which may invest without limit in commodity-linked swap agreements and other commodity-linked derivative instruments.

One of the requirements for favorable tax treatment as a regulated investment company under the Code is that the Fund must derive at least 90% of its gross income from certain qualifying sources of income. The Internal Revenue Service ("IRS") has issued a revenue ruling which holds that income derived from commodity index-linked derivatives, if earned directly by the "Fund", is not qualifying income under Subchapter M of the Code. The IRS has issued private letter rulings in which the IRS specifically concluded that income derived from an investment in a subsidiary that provides commodity-linked exposure through its investments will be qualifying income. Based on the reasoning in such rulings, the Fund will continue to seek to gain exposure to the commodity markets primarily through investments in the Subsidiary and perhaps through commodity-linked notes.

It should be noted, however, that the IRS currently has ceased the issuance of such rulings. In addition, the IRS also issued a revenue procedure, which states that the IRS will not in the future issue private letter rulings that would require a determination of whether an asset (such as a commodity index-linked note) is a "security" under the Act.

The IRS issued in September 2016 proposed regulations that would have generally treated the Fund's income inclusion (under Subpart F of the Code) with respect to the Subsidiary as qualifying income only if there were a distribution during the same taxable year out of the earnings and profits of the Subsidiary attributable to such income inclusion. In March 2019, the IRS issued final regulations (so modifying the proposed regulations) providing that (i) it will not rule on the determination of whether a financial instrument or position is a security under the Act; (ii) any earnings and profits paid out in the same taxable year as earned by a controlled foreign corporation to the Fund is treated as qualifying dividends; and (iii) that income inclusion by the Fund of its Subsidiary's earnings would be treated as other qualifying income if derived with respect to the Fund's business of investing in stock, securities, or currencies.

There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. Furthermore, the tax treatment of commodity-linked notes, other commodity-linked derivatives, and the Fund's investments in the Subsidiary may otherwise be adversely affected by future legislation, court decisions, Treasury Regulations and/or guidance issued by the IRS. Such developments could affect the character, timing and/or amount of the Fund's taxable income or any distributions made by the Fund or result in the inability of the Fund to operate as described in its prospectus.

If, during a taxable year, the Subsidiary's taxable losses (and other deductible items) exceed its income and gains, the net loss will not pass through to the Fund as a deductible amount for income tax purposes. In the event the Subsidiary's taxable gains exceed its losses and other deductible items during a taxable year, the net gain will pass through to the Fund as ordinary income for Federal income tax purposes.

The Fund's investment strategy will potentially be limited by its intention to qualify and be eligible for treatment as a regulated investment company, and can limit the Fund's ability to qualify and be treated as such. The tax treatment of certain of the Fund's investments under one or more of the qualification or distribution tests applicable to regulated investment companies is uncertain. An adverse determination or future guidance by the IRS or a change in law might affect the Fund's ability to qualify or be eligible for treatment as a regulated investment company, which could, among other things, negatively affect the Fund's share price, before- and after-tax performance, distribution rate (including a reduction in dividends) and/or its ability to achieve its investment objectives and could cause losses to the Fund (including, but not limited to, circumstances where the Fund is required to pay a Fund level tax, back taxes and/or tax penalties), as described more fully in the paragraph below.

The Fund invests in total return swaps linked to the securities of MLPs. Such strategy is relatively novel and the treatment of the Fund's investments in such total return swaps under one or more of the tests the Fund must meet to qualify as a regulated investment company is unclear. It is possible that the IRS or a court could regard the Fund's investments in such total return swaps as preventing the Fund from qualifying as a regulated investment company. Based on consultation with legal counsel, the Fund believes that, as implemented, its investment strategy should be consistent with the Fund's qualification and eligibility for treatment as a regulated investment company. If the IRS were to challenge successfully the Fund's position, the Fund could be required to pay a Fund-level tax, back taxes and/or tax penalties in order to maintain its qualification as a regulated investment company, or could fail to qualify as a regulated investment company (in which case the Fund would be subject to tax on its taxable income at corporate rates and could be subject to back taxes and/or tax penalties). In such event, the Fund may be required to change its investment strategies, pay a Fund level tax, back taxes and/or tax penalties and sell securities or other instruments at a time or in a manner unfavorable to the Fund.

Any such sales may cause the Fund to sell securities or instruments that otherwise may be favorable for the Fund, bear other adverse consequences (such as incurring short term capital gain on sales or unwinding of positions that were intended to be held for longer periods) and/or incur transaction costs. As such, such a failure to qualify for regulated investment company status could, among other things, negatively affect the Fund's share price, before- and after-tax performance, distribution rate (including a reduction in dividends) and/or its ability to achieve its investment objectives and could cause losses to the Fund (including, but not limited to, circumstances where the Fund is required to pay a Fund level tax, back taxes and/or tax penalties).

Distributions received from the Fund's investments in MLPs generally are treated as partnership return of capital under the Code, and as such, it is Management's current determination that the distributions received from its MLP investments will be comprised entirely of return of capital based on historical and present information available from such MLP partnerships.

Under the Regulated Investment Company Modernization Act of 2010, a fund is permitted to carry forward any new capital losses for an unlimited period. Additionally, such capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term under previous law.

#### Distribution Information
(Unaudited)

For purposes of Section 19 of the Investment Company Act of 1940 (the "Act"), the Fund estimated the periodic sources of any dividends paid during the period covered by this report in accordance with good accounting practice. Pursuant to Rule 19a-1(e) under the Act, the table below sets forth the actual source information for dividends paid during the six month period ended December 31, 2022 calculated as of each distribution period pursuant to Section 19 of the Act. The information below is not provided for U.S. federal income tax reporting purposes. The tax character of all dividends and distributions is reported on Form 1099-DIV (for shareholders who receive U.S. federal tax reporting) at the end of each calendar year. See the Financial Highlights section of this report for the tax characterization of distributions determined in accordance with federal income tax regulations for the fiscal year.
