Rhea-AI Filing Summary

Western Asset High Yield Opportunity Fund Inc. reports for the year ended May 31, 2026, as a diversified closed‑end fund investing primarily in below‑investment‑grade corporate bonds and senior loans. The fund was converted from a term structure to a perpetual vehicle after stockholder approval and a large issuer tender offer.

Net asset value (NAV) total return was 7.65%, while the New York Stock Exchange market price total return was -0.80%, reflecting a wider discount. The fund paid $1.14 per share in distributions, including $0.23 per share classified as return of capital. NAV ended at $11.62 with net assets of $148.9 million over 12,814,003 shares.

High‑yield corporate bonds comprised about 87% of net assets, with largest sector weights in communication services (18.1% of net assets), consumer discretionary (17.8%), energy (11.1%), industrials (10.5%) and financials (9.4%). Net investment income was $13.8 million, supporting an NII yield above 8% on average net assets. The manager implemented a 20 bps management‑fee waiver through June 6, 2026, and executed a tender offer repurchasing 9.85 million shares at $12.09, significantly shrinking the fund’s asset base.

6 terms

closed-end management investment company regulatory

"is registered as a diversified, closed-end management investment company under the Investment Company Act"

A closed-end management investment company is a pooled investment fund that raises a fixed amount of capital by issuing a set number of shares and then lists those shares for trading on an exchange; investors buy and sell shares on the market rather than redeeming them back to the fund. Think of it like a store with a fixed number of bottles on the shelf: the market price can be higher or lower than the underlying value of the assets, which matters to investors because it affects returns, liquidity and income characteristics independent of the fund’s actual holdings.

high-yield corporate fixed income securities financial

"at least 80% of its net assets in a portfolio of high-yield corporate fixed income securities"

return of capital financial

"distributions to shareholders totaling $1.14 per share of which $0.23 will be treated as return of capital"

Return of capital is when an investor receives money from their investment that is not considered profit or earnings but rather a portion of the original amount they invested. It’s similar to getting back part of your initial savings rather than gains from it. This matters because it can affect how much money an investor still has in the investment and may have tax implications.

Rule 144A regulatory

"Security is exempt from registration under Rule 144A of the Securities Act of 1933"

Rule 144A is a regulation that makes it easier for companies to sell private bonds to large investors without going through all the usual rules that apply to public sales. It matters because it helps companies raise money more quickly and privately, often attracting big investors looking for special deals.

payment-in-kind security financial

"Payment-in-kind security for which the issuer has the option of making interest payments in cash or additional securities"

senior loans financial

"Senior loans may be considered restricted in that the Fund is contractually obligated to receive approval"

Senior loans are debt that must be repaid before other debts if a borrower runs into trouble, giving lenders first claim on the company’s cash and assets — think of them as people first in line to be paid at a crowded cafeteria. They often carry lower risk and priority for recovery in defaults, so investors consider them when balancing steady interest income against credit risk and potential loss in a downturn.

Western Asset High Yield Opportunity Fund Inc.

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund’s primary investment objective is to provide high income. As a secondary investment objective, the Fund will seek capital appreciation. We believe the extensive credit research and security selection expertise of Western Asset Management Company, LLC (Western Asset), the Fund’s subadviser, will be key factors in driving Fund performance.

The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in a portfolio of high-yield corporate fixed income securities with varying maturities. Currently, the Fund focuses on lower-quality and higher-yielding opportunities in the below investment grade corporate debt markets. Under normal market conditions, the Fund may also invest up to 20% of its net assets in fixed income securities issued by U.S. or foreign governments, agencies and instrumentalities and/or fixed income securities that are of investment grade quality.

In purchasing securities and other investments for the Fund, Western Asset may take full advantage of the entire range of maturities offered by fixed income securities and may adjust the average maturity or duration of the Fund’s portfolio from time to time, depending on its assessment of the relative yields available on securities of different durations and its expectations of future changes in interest rates. The Fund is also permitted purchases of equity securities (including but not limited to common stock, preferred stock, convertible securities, warrants of U.S. and non-U.S. issuers). The Fund may utilize a variety of derivative instruments primarily for hedging and risk management purposes, although the Fund may also use derivative instruments for investment purposes.

At Western Asset, we utilize a fixed income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio management personnel, research analysts and an in-house economist. Under this team approach, management of client fixed income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization. The individuals responsible for development of investment strategy, day-to-day portfolio management, oversight and coordination of the Fund are Michael C. Buchanan, Walter Kilcullen, Christopher F. Kilpatrick, John Hwang and Ryan Kohan.

Q. What were the overall market conditions during the Fund’s reporting period?

A. The overall U.S. fixed income market experienced periods of elevated volatility but generated a positive return over the twelve-months ended May 31, 2026. The market was driven by several factors, including overall resilient U.S. economic growth, inflation pressures, U.S. Federal Reserve (“Fed”) monetary policy, global trade tensions, a 43-day government shutdown, the war in Iran, and several other geopolitical issues.

Looking back, the Fed lowered interest rates in September 2024 (the first reduction since 2020) and again in November and December 2024. The December reduction put the federal funds target rate at 4.25%-4.50%, the lowest level since December 2022. The Fed then remained on hold at its first five meetings in 2025, as it weighed the impact of U.S.

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

Fund overview (cont’d)

President’s tariffs on the economy and inflation. The central bank then lowered rates at its September, October and December 2025 meetings, citing concerns over the labor market. However, thus far in 2026 the Fed has remained on hold.

The two-year Treasury yield began the reporting period at 3.89% and ended at 3.98%, whereas the ten-year Treasury yield began the reporting period at 4.41% and ended at 4.45%. All told, the Bloomberg U.S. Aggregate Indexi returned 5.13% for the twelve months ended May 31, 2026. For comparison purposes, riskier fixed income securities, including high-yield bond and emerging market debt, produced stronger results. Over the fiscal year, the Bloomberg U.S. Corporate High Yield — 2% Issuer Cap Indexii and the JPMorgan Emerging Markets Bond Index Global (“EMBI Global”)iii returned 7.57% and 12.42%, respectively.

Q. How did we respond to these changing market conditions?

A. A number of changes were made to the portfolio during the reporting period. We trimmed our allocations to emerging markets debt (mainly U.S. dollar-denominated corporates), investment-grade corporate bonds and bank loans. From a sector perspective, within high-yield corporates we reduced exposures to capital goods and airlines (within transportation), while adding to information technology, energy (mainly exploration and production [E&P]), communication services and basic industry1 issuers. Within consumer cyclicals2, we reduced cruise line and gaming exposures while adding to retailers.

Currency forwards, which were used to help manage the Fund’s currency exposures, detracted from performance. Single-name and index credit default swaps (HY.CDX and ITRX EUR XOVER), which were used to help manage the Fund’s credit exposures, were in aggregate a detractor from returns.

Performance review

For the twelve months ended May 31, 2026, Western Asset High Yield Opportunity Fund Inc. returned 7.65% based on its net asset value (NAV)iv and -0.80% based on its New York Stock Exchange (NYSE) market price per share. The Fund’s unmanaged benchmarks, the Bloomberg U.S. High Yield — 2% Issuer Cap B Component Indexv, the Bloomberg U.S. High Yield — 2% Issuer Cap Caa Component Indexvi and the Composite Indexvii, returned 7.90%, 8.90% and 8.31% respectively, for the same period.

The Fund has a practice of seeking to maintain a relatively stable level of distributions to shareholders. This practice has no impact on the Fund’s investment strategy and may reduce the Fund’s NAV. The Fund’s manager believes the practice helps maintain the Fund’s competitiveness and may benefit the Fund’s market price and premium/discount to the Fund’s NAV.

‡ Total return assumes the reinvestment of all distributions, including returns of capital, in additional shares in accordance with the Fund’s Dividend Reinvestment Plan.

Q. What were the leading contributors to performance?

A. The largest contributor to the Fund’s relative performance was our sector allocation, specifically the Fund’s overweights to communication services and energy, sectors which outperformed relative to the overall benchmark. Within our developed market high-yield allocation, several positions were rewarded. Examples of overweight positions that outperformed within the communication services space were EchoStar, Dish DBS and Altice France. Issuers in the energy space also contributed to returns; examples of overweight positions that outperformed were midstream companies Venture Global LNG, and Crescent Energy, while avoiding New Fortress Energy, which defaulted during the period. In addition, issuers in the consumer cyclicals space contributed and examples of overweight positions that outperformed were PM General Purchaser (which does business as AM General, a U.S. military and commercial automotive manufacturer) and ZF NA Capital (the dedicated financing and corporate debt-issuing subsidiary of global automotive parts and technology supplier ZA Friedrichshafen AG).

Our allocation to emerging markets was also beneficial overall. Overweights to Colombian energy company Ecopetrol SA, Israeli-domiciled Teva Pharmaceuticals and U.A.E.-domiciled oil field services company Shelf Drilling Holdings were rewarded, as was an overweight to Republic of Angola sovereign debt.

Investment-grade rated debt in general underperformed lower quality, higher levered, and shorter duration spread product during the period. That said, a handful of overweights were

materially additive to performance. Examples of overweights that outperformed were subordinated exposure to several large global money center banks such as Lloyds Banking Group, BNP Paribas SA and UBS Group AG. In addition, exposures to energy companies such as Western Midstream Operating, The Williams, and Occidental Petroleum were beneficial.

Q. What were the leading detractors from performance?

A. While the Fund outperformed its benchmark there were a handful of positions that were not rewarded. Specifically, Spirit Airlines was one of the largest detractors from performance as it filed for Chapter 11 bankruptcy for a second time and ultimately ceased operations during the reporting period.

Although communications performed well overall, overweight allocations to CSC Holdings (which operates as a subsidiary providing cable and telecommunications services in the U.S.), iHeartCommunications (the primary subsidiary and holding company for global media and entertainment company iHeartMedia) and Clear Channel Outdoor Holdings (a multinational corporation focused on outdoor advertising) detracted.

In addition, the fact that the Fund did not hold benchmark exposure to certain communication service issuers such as Transocean and Staples, which performed well, detracted from performance. An overweight allocation to Ardagh Packaging Finance/Holdings USA was also a significant detractor.

Our overweight to bank loans underperformed. Examples are First Brands Group and Arctic Canadian Diamond Company, both companies undergoing restructuring which traded at distressed levels and detracted materially from performance during the reporting period.

RISKS: The Fund is a diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. The Fund’s common stock is traded on the New York Stock Exchange. Similar to stocks, the Fund’s share price will fluctuate with market conditions and, at the time of sale, may be worth more or less than the original investment. Shares of closed-end funds often trade at a discount to their net asset value. Diversification does not assure against market loss. The Fund’s investments are subject to a number of risks, including credit risk, inflation risk and interest rate risk. As interest rates rise, bond prices fall, reducing the value of the Fund’s share price. The Fund may invest in lower-rated high yield bonds, commonly known as “junk bonds,” which are subject to greater liquidity and credit risk (risk of default) than higher-rated obligations. The Fund is also permitted purchases of equity securities. Equity securities generally have greater price volatility than fixed income securities. Investments in foreign securities involve risks, including the possibility of losses due to changes in currency exchange rates and negative developments in the political, economic, or regulatory structure of specific countries or regions. These risks are greater in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less developed and are less stable than those of more developed countries. The Fund may make significant investments in derivative instruments. Derivative instruments can be illiquid, may disproportionately increase losses, and may have a potentially large impact on Fund performance. The Fund may invest in securities or engage in transactions that have the economic effects of leverage which can increase the risk and volatility of the Fund. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. The Fund may also invest in money market funds, including funds affiliated with the Fund’s manager and subadvisers. For more information on Fund risks, see Summary of information regarding the Fund - Principal Risk Factors in this report.

In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower.

Financial highlights (cont’d)

1	Per share amounts have been calculated using the average shares method.
2	Not covered by the current report of the independent registered public accounting firm.
3	For the period September 1, 2016 through May 31, 2017.
4	For the year ended August 31.
5	Calculation of the net loss per share (both realized and unrealized) does not correlate to the aggregate realized and unrealized gain presented in the Statement of Operations due to the timing of the sales and repurchases of Fund shares in relation to fluctuating market values of the investments of the Fund.
6	Amount represents less than $0.005 or greater than $(0.005) per share.
7	The repurchase plan was completed at an average repurchase price of $11.07 for 98,024 shares and $1,040,253 for the year ended May 31, 2020 and $13.14 for 33,902 shares and $445,351 for the year ended May 31, 2019.
8	The tender offer was completed at a price of $12.09 for 9,852,972 shares and $119,122,431 for the year ended May 31, 2026.
9	Performance figures may reflect compensating balance arrangements, fee waivers and/or expense reimbursements. In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower. Past performance is no guarantee of future results. Total returns for periods of less than one year are not annualized.
10	The total return calculation assumes that distributions are reinvested at NAV. Past performance is no guarantee of future results. Total returns for periods of less than one year are not annualized.
11	Ratios and total return for the year ended May 31, 2026, include certain non-recurring fees incurred by the Fund during the year. Without these fees, the gross and net expense ratios and the net investment income ratio would have been 1.18%, 0.98% and 8.25%, respectively, and total return based on NAV would have been 7.74%.
12	The total return calculation assumes that distributions are reinvested in accordance with the Fund’s dividend reinvestment plan. Past performance is no guarantee of future results. Total returns for periods of less than one year are not annualized.
13	Annualized.
14	The manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund.

The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in a portfolio of high-yield corporate fixed income securities with varying maturities. Corporate securities include those securities that are issued or originated by U.S. or foreign public or private corporations and other business entities.

At the Fund’s Special Meeting held on June 6, 2025, stockholders approved the proposal to convert the Fund to a perpetual fund by eliminating the Fund’s term, which was scheduled to end at the close of business on September 30, 2025, and eliminating the Fund’s fundamental policy to liquidate on or about September 30, 2025. Since the Fund maintained at least $75 million of net assets following a tender offer (See Note 5, “Tender Offer”), the Fund changed its name from “Western Asset High Yield Defined Opportunity Fund Inc.” to “Western Asset High Yield Opportunity Fund Inc.” and the conversion became effective on August 1, 2025.

The Fund follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (“ASC 946”). The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”), including, but not limited to, ASC 946. Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services typically 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 securities. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund will normally use the currency exchange rates as of 4:00 p.m. (Eastern Time). If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no

Notes to financial statements (cont’d)

value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Directors (the “Board”).  

Pursuant to policies adopted by the Board, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’s manager is assisted by the Global Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Fund’s manager and the Board. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

38

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

•

 Level 1 — unadjusted quoted prices in active markets for identical investments

•

 Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•

 Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets carried at fair value:

Change in unrealized appreciation (depreciation) includes net unrealized appreciation (depreciation) resulting from changes in investment values during the reporting period and the reversal of previously recorded unrealized appreciation (depreciation) when gains or losses are realized.

(b) Forward foreign currency contracts. The Fund enters into a forward foreign currency contract to hedge against foreign currency exchange rate risk on its non-U.S. dollar denominated securities or to facilitate settlement of a foreign currency denominated portfolio transaction. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price with delivery and settlement at a future date. The contract is marked-to-market daily and the change in value is recorded by the Fund as an unrealized gain or loss. When a forward foreign currency contract is closed, through either delivery or offset by entering into another forward foreign currency contract, the Fund recognizes a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it is closed.

Forward foreign currency contracts involve elements of market risk in excess of the amounts reflected on the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the foreign exchange rate underlying the forward foreign currency contract. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

(c) Swap agreements. The Fund invests in swaps for the purpose of managing its exposure to interest rate, credit or market risk, or for other purposes. The use of swaps

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

41

Notes to financial statements (cont’d)

involves risks that are different from those associated with other portfolio transactions. Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract (“OTC Swaps”) or centrally cleared (“Centrally Cleared Swaps”). Unlike Centrally Cleared Swaps, the Fund has credit exposure to the counterparties of OTC Swaps.

In a Centrally Cleared Swap, immediately following execution of the swap, the swap agreement is submitted to a clearinghouse or central counterparty (the “CCP”) and the CCP becomes the ultimate counterparty of the swap agreement. The Fund is required to interface with the CCP through a broker, acting in an agency capacity. All payments are settled with the CCP through the broker. Upon entering into a Centrally Cleared Swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities.

Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of Centrally Cleared Swaps, if any, is recorded as a net receivable or payable for variation margin on the Statement of Assets and Liabilities. Gains or losses are realized upon termination of the swap agreement. Collateral, in the form of restricted cash or securities, may be required to be held in segregated accounts with the Fund’s custodian in compliance with the terms of the swap contracts. Securities posted as collateral for swap contracts are identified in the Schedule of Investments and restricted cash, if any, is identified on the Statement of Assets and Liabilities. Risks may exceed amounts recorded in the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts’ terms, and the possible lack of liquidity with respect to the swap agreements.

OTC Swap payments received or made at the beginning of the measurement period are reflected as a premium or deposit, respectively, on the Statement of Assets and Liabilities. These upfront payments are amortized over the life of the swap and are recognized as realized gain or loss in the Statement of Operations. Net periodic payments received or paid by the Fund are recognized as a realized gain or loss in the Statement of Operations.

The Fund’s maximum exposure in the event of a defined credit event on a credit default swap to sell protection is the notional amount. As of May 31, 2026, the Fund did not hold any credit default swaps to sell protection.

For average notional amounts of swaps held during the year ended May 31, 2026, see Note 4.

Credit default swaps

The Fund enters into credit default swap (“CDS”) contracts for investment purposes, to manage its credit risk or to add leverage. CDS agreements involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party, typically corporate or sovereign issuers, on a specified obligation, or in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising a credit index. The Fund may use a CDS to provide protection against defaults of the issuers (i.e., to reduce risk where the Fund has exposure to an issuer) or to take an active long or short position with respect to the likelihood of a particular issuer’s default. As a seller of protection, the Fund generally receives an upfront payment or a stream of payments throughout the term of the swap,

42

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

provided that there is no credit event. If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the maximum potential amount of future payments (undiscounted) that the Fund could be required to make under a CDS agreement would be an amount equal to the notional amount of the agreement. These amounts of potential payments will be partially offset by any recovery of values from the respective referenced obligations. As a seller of protection, the Fund effectively adds leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. As a buyer of protection, the Fund generally receives an amount up to the notional value of the swap if a credit event occurs.

Implied spreads are the theoretical prices a lender receives for credit default protection. When spreads rise, market perceived credit risk rises and when spreads fall, market perceived credit risk falls. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to enter into the agreement. Wider credit spreads and decreasing market values, when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. Credit spreads utilized in determining the period end market value of CDS agreements on corporate or sovereign issues are disclosed in the Schedule of Investments and serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for credit derivatives. For CDS agreements on asset-backed securities and credit indices, the quoted market prices and resulting values, particularly in relation to the notional amount of the contract as well as the annual payment rate, serve as an indication of the current status of the payment/performance risk.

The Fund’s maximum risk of loss from counterparty risk, as the protection buyer, is the fair value of the contract (this risk is mitigated by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty). As the protection seller, the Fund’s maximum risk is the notional amount of the contract. CDS are considered to have credit risk-related contingent features since they require payment by the protection seller to the protection buyer upon the occurrence of a defined credit event.

Entering into a CDS agreement involves, to varying degrees, elements of credit, market and documentation risk in excess of the related amounts recognized on the 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 agreement may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreement, and that there will be unfavorable changes in net interest rates.

(d) Loan participations. The Fund may invest in loans arranged through private negotiation between one or more financial institutions. The Fund’s investment in any such loan may be in the form of a participation in or an assignment of the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement related to the loan, or any rights of offset against the borrower and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the participation.

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

43

Notes to financial statements (cont’d)

The Fund assumes the credit risk of the borrower, the lender that is selling the participation and any other persons interpositioned between the Fund and the borrower. In the event of the insolvency of the lender selling the participation, the Fund may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower.

(e) Securities traded on a when-issued and delayed delivery basis. The Fund may trade securities on a when-issued or delayed delivery basis. In when-issued and delayed delivery transactions, the securities are purchased or sold by the Fund with payment and delivery taking place in the future in order to secure what is considered to be an advantageous price and yield to the Fund at the time of entering into the transaction.

Purchasing such securities involves risk of loss if the value of the securities declines prior to settlement. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.

(f) Foreign currency translation. Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the respective dates of such transactions.

The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, including gains and losses on forward foreign currency contracts, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the values of assets and liabilities, other than investments in securities, on the date of valuation, resulting from changes in exchange rates.

Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of, among other factors, the possibility of lower levels of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability.

(g) Credit and market risk. The Fund invests in high-yield and emerging market instruments that are subject to certain credit and market risks. The yields of high-yield and emerging market debt obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading. The consequences of political, social, economic or diplomatic changes may have disruptive effects on the market prices of

44

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

investments held by the Fund. The Fund’s investments in non-U.S. dollar denominated securities may also result in foreign currency losses caused by devaluations and exchange rate fluctuations.

Investments in securities that are collateralized by real estate mortgages are subject to certain credit and liquidity risks. When market conditions result in an increase in default rates of the underlying mortgages and the foreclosure values of underlying real estate properties are materially below the outstanding amount of these underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. Such market conditions may significantly impair the value and liquidity of these investments and may result in a lack of correlation between their credit ratings and values.

(h) Foreign investment risks. The Fund’s investments in foreign securities may involve risks not present in domestic investments. Since securities may be denominated in foreign currencies, may require settlement in foreign currencies or may pay interest or dividends in foreign currencies, changes in the relationship of these foreign currencies to the U.S. dollar can significantly affect the value of the investments and earnings of the Fund. Foreign investments may also subject the Fund to foreign government exchange restrictions, expropriation, taxation or other political, social or economic developments, all of which affect the market and/or credit risk of the investments.

(i) Counterparty risk and credit-risk-related contingent features of derivative instruments. The Fund may invest in certain securities or engage in other transactions where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s subadviser attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse. 

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter (“OTC”) derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or net asset value per share over

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

45

Notes to financial statements (cont’d)

a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific for OTC traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

As of May 31, 2026, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(j) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities, which are amortized to the earliest call date. Paydown gains and losses on mortgage- and asset-backed securities are recorded as adjustments to interest income. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(k) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared quarterly and paid on a monthly basis. Distributions of net realized gains, if any, are declared at least annually. The actual source of the Fund’s fiscal year distributions may be from net investment income, realized capital gains, return of capital or a combination of such amounts. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(l) Federal and other taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986, as amended (the “Code”), applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing

46

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of May 31, 2026, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for the prior three fiscal years are subject to examination by the Internal Revenue Service and state departments of revenue.

Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates. In some cases, the Fund may be entitled to reclaim all or a portion of such taxes, and such reclaim amounts, if any, are reflected as a dividend receivable in the Statement of Assets and Liabilities and dividend income in the Statement of Operations. In many cases, however, the Fund may not receive such amounts for an extended period of time, depending on the country of investment.

(m) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. During the current year, the Fund had no reclassifications.

2. Investment management agreement and other transactions with affiliates

Franklin Templeton Fund Adviser, LLC (“FTFA”) is the Fund’s investment manager. Western Asset Management Company, LLC (“Western Asset”) is the Fund’s subadviser. Western Asset Management Company Pte. Ltd. (“Western Asset Singapore”), Western Asset Management Company Ltd (“Western Asset Japan”) and Western Asset Management Company Limited (“Western Asset London”) serve as additional subadvisers to the Fund, under additional subadvisory agreements with Western Asset. FTFA, Western Asset, Western Asset Singapore, Western Asset Japan and Western Asset London are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

FTFA provides administrative and certain oversight services to the Fund. The Fund pays FTFA an investment management fee, calculated daily and paid monthly, at an annual rate of 0.80% of the Fund’s average daily net assets.

FTFA delegates to Western Asset the day-to-day portfolio management of the Fund. Western Asset Singapore, Western Asset Japan and Western Asset London provide certain subadvisory services to the Fund relating to currency transactions and investments in non-U.S. dollar denominated debt securities. For its services, FTFA pays Western Asset a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund. In turn, Western Asset pays Western Asset Singapore, Western Asset Japan and Western Asset London a monthly subadvisory fee in an amount equal to 100% of the management fee paid to Western Asset on the assets that Western Asset allocates to each such non-U.S. subadviser to manage.

Effective June 30, 2026, Western Asset Japan will cease to serve as a subadviser to the Fund.

The manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund (the “affiliated money market fund waiver”).

Western Asset High Yield Opportunity Fund Inc. 2026 Annual Report

Board approval of management and subadvisory agreements (unaudited)

Background

The Investment Company Act of 1940, as amended (the “1940 Act”), requires that the Board of Directors (the “Board”) of Western Asset High Yield Opportunity Fund Inc. (the “Fund”), including a majority of its members who are not considered to be “interested persons” under the 1940 Act (the “Independent Directors”) voting separately, approve on an annual basis the continuation of the investment management agreement (the “Management Agreement”) between the Fund and the Fund’s manager, Franklin Templeton Fund Adviser, LLC (the “Manager”), and the sub-advisory agreements (individually, a “Sub-Advisory Agreement,” and collectively, the “Sub-Advisory Agreements”) with the Manager’s affiliates, Western Asset Management Company, LLC (“Western Asset”), Western Asset Management Company Limited (“Western Asset London”) and Western Asset Management Company Pte. Ltd. (“Western Asset Singapore,” and together with Western Asset and Western Asset London, the “Sub-Advisers”), with respect to the Fund.

At an in-person meeting (the “Contract Renewal Meeting”) held on May 12-13, 2026, the Board, including the Independent Directors, considered and approved the continuation of each of the Management Agreement and the Sub-Advisory Agreements for an additional one-year period. To assist in its consideration of the renewal of each of the Management Agreement and the Sub-Advisory Agreements, the Board received and considered extensive information (together with the information provided at the Contract Renewal Meeting, the “Contract Renewal Information”) about the Manager and the Sub-Advisers, as well as the management and sub-advisory arrangements for the Fund and the other closed-end funds in the same complex under the Board’s purview (the “Franklin Templeton Closed-end Funds”), certain portions of which are discussed below.

A presentation made by the Manager and the Sub-Advisers to the Board at the Contract Renewal Meeting in connection with the Board’s evaluation of each of the Management Agreement and the Sub-Advisory Agreements encompassed the Fund and other Franklin Templeton Closed-end Funds. In addition to the Contract Renewal Information, the Board received performance and other information throughout the year related to the respective services rendered by the Manager and the Sub-Advisers to the Fund. The Board’s evaluation took into account the information received throughout the year and also reflected the knowledge and experience gained as members of the Boards of the Fund and other Franklin Templeton Closed-end Funds with respect to the services provided to the Fund by the Manager and the Sub-Advisers. The information received and considered by the Board (including its various committees) in conjunction with both the Contract Renewal Meeting and throughout the year was both written and oral. The contractual arrangements discussed below are the product of multiple years of review and negotiation and information received and considered by the Board during each of those years.

Board approval of management and subadvisory agreements (unaudited) (cont’d)

At an in-person meeting held on April 24, 2026, the Independent Directors, in preparation for the Contract Renewal Meeting, met in a private session with their independent legal counsel to review the Contract Renewal Information regarding the Franklin Templeton Closed-end Funds, including the Fund, received to date. No representatives of the Manager or the Sub-Advisers participated in this meeting. Following the April 24, 2026 meeting, the Independent Directors submitted certain questions and requests for additional information to Fund management. The Independent Directors also met in private sessions with their independent legal counsel to consider the Contract Renewal Information and Fund management’s responses to the Independent Directors’ questions and requests for additional information in advance of and during the Contract Renewal Meeting. The discussion below reflects all of these reviews.

The Manager provides the Fund with investment advisory and administrative services pursuant to the Management Agreement and the Sub-Advisers together provide the Fund with investment sub-advisory services pursuant to the Sub-Advisory Agreements. The discussion below covers both the advisory and administrative functions being rendered by the Manager, each such function being encompassed by the Management Agreement, and the investment sub-advisory functions being rendered by the Sub-Advisers pursuant to the Sub-Advisory Agreements.

Board Approval of Management Agreement and Sub-Advisory Agreements

The Independent Directors were advised by separate independent legal counsel throughout the process. Prior to voting, the Independent Directors received a memorandum discussing the legal standards for their consideration of the proposed continuation of the Management Agreement and the Sub-Advisory Agreements. The Independent Directors considered the Management Agreement and each Sub-Advisory Agreement separately during the course of their review. In doing so, they noted the respective roles of the Manager and the Sub-Advisers in providing services to the Fund.

In approving the continuation of the Management Agreement and Sub-Advisory Agreements, the Board, including the Independent Directors, considered a variety of factors, including those factors discussed below. No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the continuation of the Management Agreement and the Sub-Advisory Agreements. Each Director may have attributed different weight to the various factors in evaluating the Management Agreement and the Sub-Advisory Agreements.

After considering all relevant factors and information, the Board, exercising its reasonable business judgment, determined that the continuation of the Management Agreement and Sub-Advisory Agreements was in the best interests of the Fund’s stockholders and approved the continuation of each such agreement for an additional one-year period.

56

Western Asset High Yield Opportunity Fund Inc.

Nature, Extent and Quality of the Services under the Management Agreement and Sub-Advisory Agreements

The Board received and considered Contract Renewal Information regarding the nature, extent, and quality of services provided to the Fund by the Manager and the Sub-Advisers under the Management Agreement and the Sub-Advisory Agreements, respectively, during the past year. The Board noted information received at regular meetings throughout the year related to the services provided by the Manager in its management of the Fund’s affairs and the Manager’s role in coordinating the activities of the Sub-Advisers and the Fund’s other service providers. The Board observed that the scope of services provided by the Manager and the Sub-Advisers, and of the undertakings required of the Manager and Sub-Advisers in connection with those services, including maintaining and monitoring their respective compliance programs as well as the Fund’s compliance programs, had expanded over time as a result of regulatory, market and other developments. The Board also noted that on a regular basis it received and reviewed information from the Manager and the Sub-Advisers regarding the Fund’s compliance policies and procedures established pursuant to Rule 38a-1 under the 1940 Act. The Board also considered the risks borne by the Manager, the Sub-Advisers and their respective affiliates on behalf of the Fund, including entrepreneurial, operational, reputational, litigation and regulatory risks, as well as the Manager’s and the Sub-Advisers’ risk management processes.

The Board reviewed the qualifications, backgrounds, and responsibilities of the Manager’s senior personnel and the Sub-Advisers’ portfolio management teams primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered, based on its knowledge of the Manager and its affiliates, the financial resources of Franklin Resources, Inc., the parent organization of the Manager and the Sub-Advisers. The Board recognized the importance of having a fund manager with significant resources.

The Board considered the division of responsibilities between the Manager and the Sub-Advisers under the Management Agreement and the Sub-Advisory Agreements, respectively, including the Manager’s coordination and oversight of the services provided to the Fund by the Sub-Advisers and other fund service providers and Western Asset’s coordination and oversight of the services provided to the Fund by Western Asset London and Western Asset Singapore. The Management Agreement permits the Manager to delegate certain of its responsibilities, including its investment advisory duties thereunder, provided that the Manager, in each case, will supervise the activities of the delegee.

In reaching its determinations regarding continuation of the Management Agreement and the Sub-Advisory Agreements, the Board took into account that Fund stockholders, in pursuing their investment goals and objectives, may have purchased their shares of the

Western Asset High Yield Opportunity Fund Inc.

57

Board approval of management and subadvisory agreements (unaudited) (cont’d)

Fund based upon the reputation and the investment style, philosophy and strategy of the Manager and the Sub-Advisers, as well as the resources available to the Manager and the Sub-Advisers.

The Board concluded that, overall, the nature, extent, and quality of the management and other services provided (and expected to be provided) to the Fund under the Management Agreement and the Sub-Advisory Agreements were satisfactory.

Fund Performance

The Board received and considered information regarding Fund performance, including information and analyses (the “Broadridge Performance Information”) for the Fund, as well as for a group of comparable funds (the “Performance Universe”) selected by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent third-party provider of investment company data. The Board was provided with a description of the methodology Broadridge used to determine the similarity of the Fund with the funds included in the Performance Universe. It was noted that while the Board found the Broadridge Performance Information generally useful, they recognized its limitations, including that the data may vary depending on the end date selected, and that the results of the performance comparisons may vary depending on the selection of the peer group and its composition over time. The Board also noted that Board members had received and discussed with the Manager and the Sub-Advisers information throughout the year at periodic intervals comparing the Fund’s performance against its benchmark and against the Fund’s peers. In addition, the Board considered the Fund’s performance in view of overall financial market conditions.

The Broadridge Performance Information comparing the Fund’s performance to that of its Performance Universe, consisting of the Fund and all closed-end non-leveraged high yield funds, regardless of asset size, showed, among other data, that based on net asset value per share, the Fund’s performance was below the median for the 1- and 3-year periods ended December 31, 2025, was above the median for the 5-year period ended December 31, 2025, and was equal to the median for the 10-year period ended December 31, 2025. The Board noted the explanations from the Manager and the Sub-Advisers regarding the Fund’s relative performance versus the Performance Universe for the various periods. The Board also took into account the limited size of the Performance Universe.

Based on the reviews and discussions of Fund performance and considering other relevant factors, including those noted above, the Board concluded, under the circumstances, that continuation of the Management Agreement and the Sub-Advisory Agreements for an additional one-year period would be consistent with the interests of the Fund and its stockholders.

58

Western Asset High Yield Opportunity Fund Inc.

Management and Sub-Advisory Fees and Expense Ratios

The Board reviewed and considered the contractual management fee (the “Contractual Management Fee”) and the actual management fee (the “Actual Management Fee”) payable by the Fund to the Manager under the Management Agreement and the sub-advisory fees (the “Sub-Advisory Fees”) payable by the Manager to the Sub-Advisers under the Sub-Advisory Agreements in view of the nature, extent and overall quality of the management, investment advisory and other services provided by the Manager and the Sub-Advisers, respectively. The Board noted that the Sub-Advisory Fee payable to Western Asset under its Sub-Advisory Agreement with the Manager is paid by the Manager, not the Fund, and, accordingly, that the retention of Western Asset does not increase the fees or expenses otherwise incurred by the Fund’s stockholders. Similarly, the Board noted that the Sub-Advisory Fees payable to Western Asset London and Western Asset Singapore under their respective Sub-Advisory Agreements with Western Asset are paid by Western Asset, not the Fund, and, accordingly, that the retention of Western Asset London and Western Asset Singapore does not increase the fees or expenses otherwise incurred by the Fund’s stockholders.

In addition, the Board received and considered information and analyses prepared by Broadridge (the “Broadridge Expense Information”) comparing the Contractual Management Fee and the Actual Management Fee and the Fund’s actual total expenses with those of funds in an expense group, as well as a broader group of funds (the “Expense Universe”), each selected and provided by Broadridge. The comparison was based upon the constituent funds’ latest fiscal years. It was noted that while the Board found the Broadridge Expense Information generally useful, they recognized its limitations, including that the data may vary depending on the selection of the peer group.

The Broadridge Expense Information showed that the Fund’s Contractual Management Fee was equal to the Expense Universe median. The Broadridge Expense Information also showed that the Fund’s Actual Management Fee was below the Expense Universe median. The Broadridge Expense Information also showed that the Fund’s actual total expenses were above the Expense Universe median. The Board took into account management’s discussion of the Fund’s expenses and noted the limited size of the Expense Universe.

The Board also reviewed Contract Renewal Information regarding fees charged by the Manager and/or the Sub-Advisers to other U.S. clients investing primarily in an asset class similar to that of the Fund, including, where applicable, institutional and separate accounts. The Manager reviewed with the Board the differences in services provided to these different types of accounts, noting that the Fund is provided with certain administrative services, office facilities, and Fund officers, and that the Fund is subject not only to heightened regulatory requirements relative to institutional clients but also to requirements for listing on the New York Stock Exchange, and that the Manager coordinates and

Western Asset High Yield Opportunity Fund Inc.

59

Board approval of management and subadvisory agreements (unaudited) (cont’d)

oversees the provision of services to the Fund by other fund service providers. The Board considered the fee comparisons in view of the different services provided in managing these other types of clients and funds.

The Board considered the overall management fee, the fees of the Sub-Advisers and the amount of the management fee retained by the Manager after payment of the Sub-Advisory Fees in each case in view of the services rendered for those amounts. The Board also received an analysis of complex-wide management fees provided by the Manager, which, among other things, set out a framework of fees based on asset classes.

Taking all of the above into consideration, as well as the factors identified below, the Board determined that the management fee and the Sub-Advisory Fees were reasonable in view of the nature, extent and overall quality of the management, investment advisory and other services provided by the Manager and the Sub-Advisers to the Fund under the Management Agreement and the Sub-Advisory Agreements, respectively.

Manager Profitability

The Board, as part of the Contract Renewal Information, received an analysis of the profitability to the Manager and its affiliates in providing services to the Fund for the Manager’s fiscal years ended September 30, 2025 and September 30, 2024. The Board also received profitability information with respect to the Franklin Templeton fund complex as a whole. In addition, the Board received Contract Renewal Information with respect to the Manager’s revenue and cost allocation methodologies used in preparing such profitability data. It was noted that the allocation methodologies had been reviewed by an outside consultant. In response to the Board’s request, the Manager provided, and the Board reviewed, information comparing the profitability of Franklin Resources, Inc. with that of publicly traded peer fund management companies. The profitability to each of the Sub-Advisers was not considered to be a material factor in the Board’s considerations since the Sub-Advisory Fee is paid by the Manager in the case of Western Asset and by Western Asset in the case of Western Asset London and Western Asset Singapore, not the Fund, although the Board noted the affiliation of the Manager with the Sub-Advisers. The profitability of the Manager and its affiliates was considered by the Board to be reasonable in view of the nature, extent and quality of services provided to the Fund.

Economies of Scale

The Board received and discussed Contract Renewal Information concerning whether the Manager realizes economies of scale if the Fund’s assets grow. The Board noted that because the Fund is a closed-end fund, it has limited ability to increase its assets. The Board determined that the management fee structure was appropriate under the circumstances. For similar reasons as stated above with respect to the Sub-Advisers’ profitability and the costs of the Sub-Advisers’ provision of services, the Board did not

60

Western Asset High Yield Opportunity Fund Inc.

consider the potential for economies of scale in the Sub-Advisers’ management of the Fund to be a material factor in the Board’s consideration of the Sub-Advisory Agreements.

Other Benefits to the Manager and the Sub-Advisers

The Board considered other benefits received by the Manager, the Sub-Advisers and their affiliates as a result of their relationship with the Fund, including the opportunity to offer additional products and services to the Fund’s stockholders. In view of the costs of providing investment management and other services to the Fund and the ongoing commitment of the Manager and the Sub-Advisers to the Fund, the Board considered that the ancillary benefits received by the Manager and its affiliates, including the Sub-Advisers, were reasonable.

UPDATED DISCLOSURES FOR THE FUND

The following additional information is provided for the Fund as of the fiscal year ended May 31, 2026.

Summary of Fund Expenses

Sales Load (as a percentage of offering price)(1)	1.00 %
Offering Expense (as a percentage of offering price)(2)	0.06 %
Dividend Reinvestment Plan Fees(3)	$5.00

Annual Operating Expenses 

	Percentage of Net Assets Attributable to Common Shares
Management Fees(4)	0.80%
Other Expenses(5)	0.47%
Total Annual Fund Operating Expenses	1.27%

(1) Represents the estimated commission with respect to the Common Stock being sold in at-the-market offerings. UBS Securities LLC will be entitled to compensation of up to 1.00% of the gross proceeds of the sale of any Common Stock under the Sales Agreement, with the exact amount of such compensation to be mutually agreed upon in writing by the Fund and UBS Securities LLC from time to time.

(2) Costs incurred by the Fund in connection with the shelf offering are recorded as a prepaid expense. These costs are amortized on a pro-rata basis as shares are sold and are presented as a reduction to the net proceeds from the sale of shares. Any deferred charges remaining at the end of the life of the shelf offering period will be expensed.

(3) Common Stockholders will pay brokerage charges if they direct the Plan Agent to sell shares of Common Stock held in a dividend reinvestment account. There are no fees charged to stockholders for participating in the Fund’s dividend reinvestment plan. However, stockholders participating in the Plan that elect to sell their shares obtained pursuant to the plan would pay $5.00 per transaction to sell shares.

(4) The Investment Manager receives an annual fee, payable monthly, in an amount equal to 0.80% of the Fund’s average daily net assets.

(5) “Other Expenses” are based on amounts incurred in the fiscal year ended May 31, 2026.

Examples

An investor would pay the following expenses on a $1,000 investment in the Fund, assuming a 5% annual return:

One Year	Three Years	Five Years	Ten Years
$24	$51	$80	$163

The above table and example are intended to assist investors in understanding the various costs and expenses directly or indirectly associated with investing in Shares of the Fund.

Western Asset High Yield Opportunity Fund Inc.

The “Example” assumes that all dividends and other distributions are reinvested at net asset value and that the percentage amounts listed in the table above under Total Annual Operating Expenses remain the same in the years shown. The above table and example and the assumption in the example of a 5% annual return are required by regulations of the SEC that are applicable to all investment companies; the assumed 5% annual return is not a prediction of, and does not represent, the projected or actual performance of the Fund’s Common Shares.

The example should not be considered a representation of past or future expenses, and the Fund’s actual expenses may be greater than or less than those shown. The Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

since the commencement of the Fund’s operations. The Fund cannot determine the reasons why the Fund’s Common Stock trades at a premium to or discount from NAV, nor can the Fund predict whether its Stock will trade in the future at a premium to or discount from NAV, or the level of any premium or discount. The Board regularly monitors the relationship between the market price and NAV of the Common Stock. If the Common Stock were to trade at a substantial discount to NAV for an extended period of time, the Board may consider the repurchase of the Fund’s Common Stock on the open market, the making of a tender offer for such shares or other programs intended to reduce the discount. The Fund cannot assure you that its Board will decide to take or propose any of these actions, or that

share repurchases or tender offers will actually reduce market discount.

Summary of information regarding the Fund (unaudited)

Investment Objectives

The Fund’s primary investment objective is to provide high income. As a secondary investment objective, the Fund will seek capital appreciation. There can be no assurance the Fund will achieve its investment objectives.

Principal Investment Policies and Strategies

The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in a portfolio of high-yield corporate fixed income securities with varying maturities. “High-yield” refers to below investment grade quality (also commonly referred to as “junk bonds”). High-yield fixed income securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. “Fixed income securities” include bonds, debentures, notes, commercial paper and other similar types of debt instruments, as well as preferred stock, convertible securities, Senior Loans, Second Lien Loans, loan participations, payment-in-kind securities, zero-coupon bonds, mortgage-backed securities, asset-backed securities, bank certificates of deposit, fixed time deposits and bankers’ acceptances. Corporate securities are those securities that are issued or originated by U.S. or foreign public or private corporations and other business entities, and do not include securities issued by governments, agencies or supranational entities. Certain fixed income instruments, such as convertible securities, may also include the right to participate in equity appreciation, and Western Asset will generally evaluate those instruments based primarily on their debt characteristics.

The Fund may invest in derivative instruments primarily for hedging and risk management purposes, although the Fund may also use derivative instruments for investment purposes. Investing in derivative instruments is not a principal investment strategy of the Fund. Derivative instruments include options contracts, futures contracts, options on futures contracts, indexed securities, currency forwards, credit linked notes, credit default swaps and other swap agreements. The Fund may use derivative instruments to gain exposure to or hedge its exposure to high-yield securities primarily through the use of credit default swaps, but may also use other derivative instruments, provided that the Fund’s exposure to credit derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its net assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. Notwithstanding the foregoing limitation, the Fund may invest without limit in derivative instruments related to currencies and interest rates, subject to the requirements of the 1940 Act provided that such currency and interest rate derivatives are used for hedging purposes only. To the extent that the security or index underlying the derivative or synthetic instrument is or is composed of corporate high-yield fixed income securities, the Fund will include such derivative and synthetic instruments for the purposes of the Fund’s policy to invest at least 80% of its net assets in a portfolio of high-yield corporate fixed income

Western Asset High Yield Opportunity Fund Inc.

73

Summary of information regarding the Fund (unaudited) (cont’d)

securities. Credit derivatives, by their design, have a high correlation to the underlying securities. The Fund may not change its policy to invest, under normal market conditions, at least 80% of its net assets in a portfolio of high-yield corporate fixed income securities with varying maturities unless it provides shareholders with at least 60 days’ written notice of such change.

Below investment grade fixed income securities are rated below “BBB-” by S&P or Fitch, below “Baa3” by Moody’s or comparably rated by another NRSRO or, if unrated, determined by Western Asset to be of comparable quality. Below investment grade fixed income securities are commonly referred to as “high-yield” or “junk” bonds and are regarded as having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. In the event that a security receives different ratings from different NRSROs, the Fund will treat the security as being rated in the lowest rating category received from an NRSRO.

Under normal market conditions, the Fund may also invest up to 20% of its net assets in fixed income securities issued by U.S. or foreign governments, agencies and instrumentalities and/or fixed income securities that are investment grade quality.

The Fund may invest up to 20% of its net assets in securities that, at the time of investment, are considered Illiquid Securities.

The Fund may invest up to 20% of its net assets in government debt securities, including those of emerging market issuers or of other non-US issuers.

No more than 10% of the Fund’s net assets may be invested in any issuer, except securities issued by the U.S. government and its agencies.

The Fund may purchase equity securities (including but not limited to common stock, preferred stock, convertible securities, and warrants of U.S. and non-U.S. issuers) directly. The Fund may sell certain equities or fixed income securities short including, but not limited to, U.S. Treasuries, for investment and/or hedging purposes.

The Fund may lend portfolio securities so long as the terms and the structure of such loans are not inconsistent with the requirements of the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund does not currently intend to make loans of portfolio securities with a value in excess of 33 1/3% of the value of its net assets (including such loans).

Temporary Defensive Strategies. At times Western Asset may judge that conditions in the markets for fixed income securities make pursuing the Fund’s primary investment strategy inconsistent with the best interests of its shareholders. At such times Western Asset may, temporarily, use alternative strategies, primarily designed to reduce fluctuations in the value of the Fund’s assets. If the Fund takes a temporary defensive position, it may be

74

Western Asset High Yield Opportunity Fund Inc.

unable to achieve its investment objectives. In implementing these “defensive” strategies, the Fund may invest all or a portion of its assets in obligations of the U.S. government, its agencies or instrumentalities; other investment grade debt securities; investment grade commercial paper; certificates of deposit and bankers’ acceptances; repurchase agreements with respect to any of the foregoing investments; or any other fixed income securities that Western Asset considers consistent with this strategy. It is impossible to predict if, when or for how long the Fund will use these alternative strategies. There can be no assurance that such strategies will be successful.

Other Investment Companies. The Fund may invest in securities of other closed-end or open-end investment companies, including exchange traded funds (“ETFs”), that invest primarily in bonds or other securities and instruments of the types in which the Fund may invest directly to the extent permitted by the 1940 Act. The Fund will not consider an investment in securities of other closed-end or open-end investment companies toward meeting its policy of investing at least 80% of its net assets in high-yield securities unless such closed-end or open-end investment company has a policy of investing at least 80% of its net assets in high-yield securities.

The Fund may invest in other investment companies during periods when it has large amounts of uninvested cash, such as during periods when there is a shortage of attractive bonds available in the market, or when Western Asset believes share prices of other investment companies offer attractive values. The Fund may invest in investment companies, including money market funds, that are advised by Western Asset or its affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. As a shareholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. Western Asset will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available bond investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. The net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares. Other investment companies may have investment policies that differ from those of the Fund. In addition, to the extent the Fund invests in other investment companies, the Fund will be dependent upon the investment and research abilities of persons other than Western Asset.

Principal Risk Factors

There is no assurance that the Fund will meet its investment objectives. You may lose money on your investment in the Fund. The value of the Fund’s shares may go up or down, sometimes rapidly and unpredictably. Market conditions, financial conditions of issuers represented in the Fund’s portfolio, investment strategies, portfolio management, and other factors affect the volatility of the Fund’s shares. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

The following section includes a summary of the principal risks of investing in the Fund.

Investment and Market Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire amount that you invest. Your investment in Common Stock represents an indirect investment in the fixed income securities and other assets owned by the Fund, most of which could be purchased directly. The value of the Fund’s portfolio securities may move up or down, sometimes rapidly and unpredictably. The Fund intends to take advantage of that Western Assets believes to be current market dislocations by buying debt and other securities at depressed prices, but if such dislocations do not persist during the period when the Fund is investing the net proceeds of this offering, the Fund’s returns may be adversely affected. In addition, if the current global economic downturn continues or deteriorates further, the ability of issuers to service their obligations could be materially and adversely affected. At any point in time, your Common Stock may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Below Investment Grade (High-Yield or Junk Bond) Securities Risk. High yield bonds, often called “junk” bonds, have a higher risk of issuer default or may be in default and are considered speculative. Changes in economic conditions or developments regarding the individual issuer are more likely to cause price volatility and weaken the capacity of such securities to make principal and interest payments than is the case for higher grade debt securities. The value of lower-quality debt securities often fluctuates in response to company, political, or economic developments and can decline significantly over short as well as long periods of time or during periods of general or regional economic difficulty. High yield bonds may also have lower liquidity as compared to higher-rated securities, which means the Fund may have difficulty selling them at times, and it may have to apply a greater degree of judgment in establishing a price for purposes of valuing Fund shares. High yield bonds generally are issued by less creditworthy issuers. Issuers of high yield bonds may have a larger amount of outstanding debt relative to their assets than issuers of investment grade bonds. In the event of an issuer’s bankruptcy, claims of other creditors may have priority over the claims of high yield bond holders, leaving few or no assets available to repay high yield bond holders. The Fund may incur expenses to the extent

76

Western Asset High Yield Opportunity Fund Inc.

necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer. High yield bonds frequently have redemption features that permit an issuer to repurchase the security from the Fund before it matures. If the issuer redeems high yield bonds, the Fund may have to invest the proceeds in bonds with lower yields and may lose income.

Fixed Income Securities Risk. In addition to the risks described elsewhere in this section with respect to valuations and liquidity, fixed income securities, including high-yield securities, are also subject to certain risks, including:

Issuer Risk. The value of fixed income securities may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Interest Rate Risk. The market price of the Fund’s investments will change in response to changes in interest rates and other factors. During periods of declining interest rates, the market price of fixed income securities generally rises. Conversely, during periods of rising interest rates, the market price of such securities generally declines. The magnitude of these fluctuations in the market price of fixed income securities is generally greater for securities with longer maturities. Fluctuations in the market price of the Fund’s securities will not affect interest income derived from securities already owned by the Fund, but will be reflected in the Fund’s net asset value. The Fund may utilize certain strategies, including investments in structured notes or interest rate swap or cap transactions, for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Fund’s exposure to interest rate risk, although there is no assurance that it will do so or that such strategies will be successful.

Prepayment Risk. During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest the proceeds from such prepayment in lower yielding securities, which may result in a decline in the Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. Debt securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”). An issuer may choose to redeem a debt security if, for example, the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. Senior Loans and Second Lien Loans typically do not have call protection. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.

Reinvestment Risk. 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 fixed

Western Asset High Yield Opportunity Fund Inc.

77

Summary of information regarding the Fund (unaudited) (cont’d)

income securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Fund’s Common Stock price or its overall return.

Credit Risk. Credit risk is the risk that one or more fixed income securities in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. If the recent adverse conditions in the credit markets continue to adversely affect the broader global economy, the credit quality of issuers of fixed income securities in which the Fund may invest would be more likely to decline, all other things being equal. Changes by an NRSRO in its rating of securities and in the ability of an issuer to make scheduled payments may also affect the value of the Fund’s investments. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which invests solely in investment grade securities. The prices of lower grade securities are generally more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Fixed income securities of below investment grade quality are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default.

Foreign Securities and Emerging Markets Risk. A fund that invests in foreign (non-U.S.) securities may experience more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Investments in foreign securities (including those denominated in U.S. dollars) are subject to economic and political developments in the countries and regions where the issuers operate or are domiciled, or where the securities are traded, such as changes in economic or monetary policies. Values may also be affected by restrictions on receiving the investment proceeds from a foreign country. Less information may be publicly available about foreign companies than about U.S. companies. Foreign companies are generally not subject to the same accounting, auditing and financial reporting standards as are U.S. companies. In addition, the Fund’s investments in foreign securities may be subject to the risk of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of foreign currency, confiscatory taxation, political or financial instability and adverse diplomatic developments. In addition, there may be difficulty in obtaining or enforcing a court judgment abroad. Dividends or interest on, or proceeds from the sale of, foreign securities may be subject to non-U.S. withholding taxes, and special U.S. tax considerations may apply.

The risks of foreign investment are greater for investments in emerging markets. “Emerging market country” is defined as any country which is, at the time of investment, it is (i) represented in the J.P. Morgan Emerging Markets Bond Index Global Diversified or the J.P.

78

Western Asset High Yield Opportunity Fund Inc.

Morgan Corporate Emerging Market Bond Index Broad or (ii) categorized by the World Bank in its annual categorization as middle- or low-income. Emerging market countries typically have economic and political systems that are less fully developed, and that can be expected to be less stable, than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in price volatility. Emerging market countries may have policies that restrict investment by foreigners, that require governmental approval prior to investments by foreign persons, or that prevent foreign investors from withdrawing their money at will. An investment in emerging market securities should be considered speculative.

Foreign Currency Risk. The value of investments denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The fund may be unable or may choose not to hedge its foreign currency exposure.

Repurchase Agreements Risk. Subject to its investment objective and policies, the Fund may invest in repurchase agreements for leverage or investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including (1) possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; (2) possible lack of access to income on the underlying security during this period; and (3) expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in debt securities, the Fund follows procedures approved by the Fund’s Board of Directors that are designed to minimize such risks. These procedures include effecting repurchase transactions only with large, well-capitalized and well-established financial institutions whose financial condition will be continually monitored by Western Asset. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

Derivatives Risk. The Fund may utilize a variety of derivative instruments, primarily for hedging and risk management purposes although the Fund may also use derivative instruments for investment purposes. Derivative instruments include options contracts, derivative instruments related to currencies, forward contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements. A derivative is a financial contract whose value depends on changes in the value of one or more underlying assets or reference rates. Derivatives are subject to a number of risks described elsewhere in this prospectus, such as liquidity risk, interest rate risk, credit risk and management risk. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to its derivative transactions will affect the value of those instruments. By using derivatives that expose the Fund to counterparties, the Fund assumes the risk that its counterparties could experience financial hardships that could call into question their continued ability to perform their obligations. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying security. As a result, concentrations of such derivatives in any one counterparty would subject the Fund to an additional degree of risk with respect to defaults by such counterparty. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of a derivative may not correlate perfectly with an underlying asset, interest rate or index. Suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. If the Fund invests in a derivative instrument, it could lose more than the principal amount invested. Derivative instruments can be illiquid, may disproportionately increase losses, and may have a potentially large impact on Fund performance.

The Fund operates under Rule 18f-4 under the 1940 Act which, among other things, governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 requires funds that invest in derivative instruments beyond a specified limited amount to apply a value at risk (VaR) based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. A fund that uses derivative instruments in a limited amount is not subject to the full requirements of Rule 18f-4. Compliance with Rule 18f-4 by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. Rule 18f-4 may limit the Fund’s ability to use

80

Western Asset High Yield Opportunity Fund Inc.

derivatives as part of its investment strategy and may not work as intended to limit losses from derivatives.

Leverage Risk. As a fundamental policy, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary or emergency purposes as permitted by the 1940 Act. The Fund may take on leveraging risk by, among other things, purchasing securities on a when-issued or delayed delivery basis, entering into credit default swaps or futures contracts, engaging in short sales or writing options on portfolio securities. When the Fund engages in transactions that have a leveraging effect on the Fund’s portfolio, the value of the Fund will be more volatile and all other risks will tend to be compounded. This is because leverage generally magnifies the effect of any increase or decrease in the value of the Fund’s underlying asset or creates investment risk with respect to a larger pool of assets than the Fund would otherwise have. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments in order to segregate assets or for other cash needs, the Fund may suffer a loss.

Management Risk. The Fund is subject to management risk because it is an actively managed investment portfolio. Western Asset, the Non-U.S. Subadvisers and each individual portfolio manager may not be successful in selecting the best performing securities or investment techniques, and the Fund’s performance may lag behind that of similar funds.

Government Intervention in Financial Markets Risk. U.S. federal and state governments and foreign governments, their regulatory agencies or self-regulatory organizations may take additional actions that affect the regulation of the securities in which the Fund invests, or the issuers of such securities, in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. Western Asset will monitor developments and seek to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so.

Asset-Backed, Mortgage-Backed or Mortgage-Related Securities Risk. To the extent the Fund invests in asset-backed, mortgage-backed or mortgage-related securities, its exposure to prepayment and extension risks may be greater than other investments in fixed income

Western Asset High Yield Opportunity Fund Inc.

81

Summary of information regarding the Fund (unaudited) (cont’d)

securities. Mortgage derivatives held by the Fund may have especially volatile prices and may have a disproportionate effect on the Fund’s share price. Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. In addition, mortgage-related securities are subject to prepayment risk—the risk that borrowers may pay off their mortgages sooner than expected, particularly when interest rates decline. This can reduce the Fund’s returns because the Fund may have to reinvest that money at lower prevailing interest rates. The Fund’s investments in other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities.

Market Price Discount from Net Asset Value Risk. Shares of closed-end investment companies frequently trade at a discount from their net asset value. This risk is separate and distinct from the risk that the Fund’s net asset value could decrease as a result of its investment activities and may be a greater risk to investors expecting to sell their Common Stock in a relatively short period following completion of this offering. Whether investors will realize gains or losses upon the sale of the Common Stock will depend not upon the Fund’s net asset value but upon whether the market price of the Common Stock at the time of sale is above or below the investor’s purchase price for the Common Stock. Because the market price of the Common Stock will be determined by factors such as relative supply of and demand for the Common Stock in the market, general market and economic conditions and other factors beyond the control of the Fund, the Fund cannot predict whether the Common Stock will trade at, above or below net asset value or at, above or below the initial public offering price. The Fund’s Common Stock is designed primarily for long-term investors and you should not view the Fund as a vehicle for trading purposes.

Anti-Takeover Provisions Risk. The Fund’s Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of seeking to maximize current income. The Bylaws provide that the Fund shall be subject to the provisions of the MCSAA (as defined below). There can be no assurance, however, that the provisions of the MCSAA will be sufficient to deter professional arbitrageurs that seek to cause the Fund to take actions that may not be consistent with its investment objective or aligned with the interests of long-term stockholders, such as liquidating debt investments prior to maturity, triggering taxable events for stockholders and decreasing the size of the Fund. See “Certain Provisions in the Charter and Bylaws” and “Certain Provisions in the Charter and Bylaws—Maryland Control Share Acquisition Act” (“MCSAA”). Such provisions may limit the ability of stockholders to sell their shares at a premium over prevailing market prices by discouraging an investor from seeking to obtain control of the Fund.

Western Asset High Yield Opportunity Fund Inc.

U.S. Government Debt Securities Risk. U.S. government debt securities generally do not involve the credit risks associated with investments in other types of debt securities, although, as a result, the yields available from U.S. government debt securities are generally lower than the yields available from other securities. Like other debt securities, however, the values of U.S. government securities change as interest rates fluctuate. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s net asset value. Since the magnitude of these fluctuations will generally be greater at times when the Fund’s average maturity is longer, under certain market conditions the Fund may, for temporary defensive purposes, accept lower current income from short-term investments rather than investing in higher yielding long-term securities.

Non-U.S. Government Debt Securities Risk. The Fund intends to invest in non-U.S. government debt securities. The ability of a government issuer, especially in an emerging market country, to make timely and complete payments on its debt obligations will be strongly influenced by the government issuer’s balance of payments, including export performance, its access to international credits and investments, fluctuations of interest rates and the extent of its foreign reserves. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. To the extent that a country receives payment for its exports in currencies other than U.S. dollars, its ability to make debt payments denominated in U.S. dollars could be adversely affected. If a government issuer cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks, and multinational organizations. There are no bankruptcy proceedings similar to those in the United States by which defaulted non-U.S. government debt may be collected. Additional factors that may influence a government issuer’s ability or willingness to service debt include, but are not limited to, a country’s cash flow situation, the availability of sufficient foreign exchange on the date a payment is due, the relative size of its debt service burden to the economy as a whole, and the issuer’s policy towards the International Monetary Fund, the International Bank for Reconstruction and Development and other international agencies to which a government debtor may be subject.

Senior Loans Risk. The Fund may invest in Senior Loans issued by banks, other financial institutions, and other investors to corporations, partnerships, limited liability companies and other entities to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, debt refinancings and, to a lesser extent, for general operating and other purposes. An investment in Senior Loans involves risk that the borrowers under Senior Loans may default on their obligations to pay principal or interest when due. In the event a borrower fails to pay scheduled interest or principal payments on a Senior Loan held by the Fund, the Fund will experience a reduction in its income and a decline in the market value of

Western Asset High Yield Opportunity Fund Inc.

83

Summary of information regarding the Fund (unaudited) (cont’d)

the Senior Loan, which will likely reduce dividends and lead to a decline in the net asset value of the Fund. If the Fund acquires a Senior Loan from another lender, for example, by acquiring a participation, the Fund may also be subject to credit risks with respect to that lender.

The Fund will generally invest in Senior Loans that are secured with specific collateral. However, there can be no assurance that liquidation of collateral would satisfy the borrower’s obligation in the event of non-payment or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund could experience delays and limitations on its ability to realize the benefits of the collateral securing the Senior Loan. Senior Loans are typically structured as floating rate instruments in which the interest rate payable on the obligation fluctuates with interest rate changes. As a result, the yield on Senior Loans will generally decline in a falling interest rate environment causing the Fund to experience a reduction in the income it receives from a Senior Loan. Senior Loans are generally of below investment grade quality and may be unrated at the time of investment; are generally not registered with the SEC or state securities commissions; and are generally not listed on any securities exchange. In addition, the amount of public information available on Senior Loans is generally less extensive than that available for other types of assets.

Second Lien Loans Risk. Second Lien Loans generally are subject to similar risks as those associated with investments in Senior Loans. Because Second Lien Loans are subordinated or unsecured and thus lower in priority of payment to Senior Loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second Lien Loans generally have greater price volatility than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in Second Lien Loans, which would create greater credit risk exposure for the holders of such loans. Second Lien Loans share the same risks as other below investment grade securities.

Loan Participations and Assignments Risk. The Fund may invest in participations in loans or assignments of all or a portion of loans from third parties. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund may be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a 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

84

Western Asset High Yield Opportunity Fund Inc.

borrower. Certain participations may be structured in a manner designed to avoid purchasers of participations being subject to the credit risk of the lender with respect to the participation, but even under such a structure, in the event of the lender’s insolvency, the lender’s servicing of the participation may be delayed and the assignability of the participation impaired. The Fund will acquire participations only if the lender interpositioned between the Fund and the borrower is determined by Western Asset to be creditworthy.

Common Stock Risk. The Fund may purchase equity securities (including but not limited to common stock, preferred stock, convertible securities, and warrants of U.S. and non-U.S. issuers) directly. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. In addition, the prices of common stocks are sensitive to general movements in the stock market, and a drop in the stock market may depress the prices of common stocks to which the Fund has exposure. Common stock prices fluctuate for several reasons including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting an issuer occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. The value of the common stocks in which the Fund may invest will be affected by changes in the stock markets generally, which may be the result of domestic or international political or economic news, changes in interest rates or changing investor sentiment. At times, stock markets can be volatile and stock prices can change substantially. The common stocks of smaller companies are more sensitive to these changes than those of larger companies. Common stock risk will affect the Fund’s net asset value per share, which will fluctuate as the value of the securities held by the Fund change.

Preferred Stock Risk. The Fund may invest in preferred stock. Preferred stocks are unique securities that combine some of the characteristics of both common stocks and bonds. Preferred stocks generally pay a fixed rate of return and are sold on the basis of current yield, like bonds. However, because they are equity securities, preferred stock provides equity ownership of a company, and the income is paid in the form of dividends. Preferred stocks typically have a yield advantage over common stocks as well as comparably-rated fixed income investments. Preferred stocks are typically subordinated to bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater credit risk than those debt instruments. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stocks also may be subject to optional or mandatory redemption provisions. Certain of the preferred stocks in which the Fund may invest may be convertible preferred stocks, which have risks similar to convertible securities as described below in “—Convertible Securities Risk.”

Western Asset High Yield Opportunity Fund Inc.

Convertible Securities Risk. The Fund may invest in convertible securities. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. Similar to traditional fixed income securities, the market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, when the market price of the common stock underlying a convertible security exceeds the conversion price, the convertible security tends to reflect the market price of the underlying common stock. As the market price of the underlying common stock declines, the convertible security tends to trade increasingly on a yield basis and thus may not decline in price to the same extent as the underlying common stock. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value. Convertible securities rank senior to common stock in a corporation’s capital structure but are usually subordinated to comparable nonconvertible securities. Convertible securities may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument.

Short Sales Risk. To the extent the Fund makes use of short sales for investment and/or risk management purposes, the Fund may be subject to risks associated with selling short. Short sales are transactions in which the Fund sells securities or other instruments that the Fund does not own. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund may engage in short sales where it does not own or have the right to acquire the security sold short at no additional cost. The Fund’s loss on a short sale theoretically could be unlimited in a case where the Fund is unable, for whatever reason, to close out its short position. In addition, the Fund’s short selling strategies may limit its ability to benefit from increases in the markets. If the Fund engages in short sales, it will segregate liquid assets, enter into offsetting transactions, own positions covering its obligations or otherwise cover such obligations; however, such segregation and cover requirements will not limit or offset losses on related positions. Short selling also involves a form of financial leverage that may exaggerate any losses realized by the Fund. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund.

Risk of Short Economic Exposure Through Derivatives. The use by the Fund of derivatives such as options, forwards or futures contracts for investment and/or risk management purposes may subject the Fund to risks associated with short economic exposure through

86

Western Asset High Yield Opportunity Fund Inc.

such derivatives. Taking a short economic position through derivatives exposes the Fund to the risk that it will be obligated to make payments to its counterparty if the underlying asset appreciates in value, thus resulting in a loss to the Fund. The Fund’s loss on a short position using derivatives theoretically could be unlimited.

Counterparty Risk. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant financial hardships including bankruptcy and losses as a result of exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. 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 under the derivative contract in a bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Credit Default Swap Risk. The Fund may invest in credit default swap transactions for hedging or investment purposes. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risk. The “buyer” in a credit default contract is obligated to pay the “seller” a periodic stream of payments over the term of the contract, provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or “par value,” of the reference obligation through either physical settlement or cash settlement. The Fund may be either the buyer or seller in a credit default swap transaction. If the Fund is a buyer and no event of default occurs, the Fund will have made a series of periodic payments and recover nothing of monetary value. However, if an event of default occurs, the Fund (if the buyer) will receive the full notional value of the reference obligation either through a cash payment in exchange for the asset or a cash payment in addition to owning the reference assets. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and five years, provided that there is no event of default. The sale of a credit default swap is a form of leverage.

Structured Notes and Related Instruments Risk. The Fund may invest in “structured” notes and other related instruments, which are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets, such as indexes reflecting bonds. Structured instruments may be issued by

Western Asset High Yield Opportunity Fund Inc.

87

Summary of information regarding the Fund (unaudited) (cont’d)

corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Inflation/Deflation Risk. Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Stock and distributions on the Common Stock can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to shareholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.

Risks of Futures and Options on Futures. The use by the Fund of futures contracts and options on futures contracts to hedge interest rate risks involves special considerations and risks, as described below.

• Successful use of hedging transactions depends upon Western Asset’s ability to correctly predict the direction of changes in interest rates. There can be no assurance that any particular hedging strategy will succeed.

• There might be imperfect correlation, or even no correlation, between the price movements of a futures or option contract and the movements of the interest rates being hedged. Such a lack of correlation might occur due to factors unrelated to the interest rates being hedged, such as market liquidity and speculative or other pressures on the markets in which the hedging instrument is traded.

• Hedging strategies, if successful, can reduce risk of loss by wholly or partially offsetting the negative effect of unfavorable movements in the interest rates being hedged. However, hedging strategies can also reduce opportunity for gain by offsetting the positive effect of favorable movements in the hedged interest rates.

• There is no assurance that a liquid secondary market will exist for any particular futures contract or option thereon at any particular time. If the Fund were unable to liquidate a futures contract or an option on a futures contract position due to the absence of a liquid secondary market or the imposition of price limits, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position.

• There is no assurance that the Fund will use hedging transactions. For example, if the Fund determines that the cost of hedging will exceed the potential benefit to the Fund, the Fund will not enter into such transactions.

When-Issued and Delayed-Delivery Transactions Risk. The Fund may purchase fixed income securities on a when-issued basis, and may purchase or sell those securities for delayed delivery. When-issued and delayed-delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed-delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed-delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed-delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

Portfolio Turnover Risk. Changes to the investments of the Fund may be made regardless of the length of time particular investments have been held. A high portfolio turnover rate may result in increased transaction costs for the Fund in the form of increased dealer spreads and other transactional costs, which may have an adverse impact on the Fund’s performance. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. A high portfolio turnover may increase the Fund’s current and accumulated earnings and profits, resulting in a greater portion of the Fund’s distributions being treated as a dividend to the Fund’s shareholders. The portfolio turnover rate of the Fund will vary from year to year, as well as within a given year.

Temporary Defensive Strategies Risk. When Western Asset anticipates unusual market or other conditions, the Fund may temporarily depart from its principal investment strategies as a defensive measure and invest all or a portion of its assets in obligations of the U.S. government, its agencies or instrumentalities; other investment grade debt securities; investment grade commercial paper; certificates of deposit and bankers’ acceptances; repurchase agreements with respect to any of the foregoing investments or any other fixed income securities that Western Asset considers consistent with this strategy. To the extent that the Fund invests defensively, it may not achieve its investment objectives.

Rating Agency Risk. Credit ratings are issued by rating agencies which are private services that provide ratings of the credit quality of debt obligations, including convertible securities. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risks or the liquidity of securities. Rating agencies may fail to make timely changes in credit ratings and an issuer’s current financial condition may be better or worse than a rating indicates. In addition, in recent years there have been instances in which the initial rating assigned by a rating agency to a security failed to take account of adverse economic developments which subsequently occurred, leading to losses that were not anticipated based on the initial rating. To the extent that the issuer of a security pays a rating agency for the analysis of its security, an inherent conflict of interest may exist that could affect the reliability of the rating. The ratings of a debt security may change over time. As a result, debt instruments held by the Fund could receive a higher rating or a lower rating during the period in which they are held. The Fund will not necessarily sell a security when its rating is reduced below its rating at the time of purchase.

Market Events Risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to factors such as economic events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes, labor strikes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected, the value and liquidity of the fund’s investments may be negatively affected. Ongoing armed conflicts in Europe and the Middle East have caused and could continue to cause significant market disruptions and volatility. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain fund investments as well as fund performance and liquidity. For example, following Russia’s invasion of Ukraine in 2022, Russian stocks lost all, or nearly all, of their market value. Further, recent escalations of conflict in the Middle East could lead to disruptions in local, regional, national and global markets and economies for an unknown period of time. The United States and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the United States has recently enacted and proposed to enact significant new tariffs and President Trump has directed various federal

90

Western Asset High Yield Opportunity Fund Inc.

agencies to further evaluate key aspects of U.S. trade policy, which could potentially lead to significant changes to current policies, treaties and tariffs. There continues to exist significant uncertainty about the future relationship between the U.S. and other countries with respect to such trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between the impacted nations and the U.S. For example, the United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund’s assets may go down.

Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Recently, inflation and interest rates have increased and may rise further. These circumstances could adversely affect the value and liquidity of the fund’s investments, impair the fund’s ability to satisfy redemption requests, and negatively impact the fund’s performance.

Operational Risk. The valuation of the Fund’s investments may be negatively impacted because of the operational risks arising from factors such as processing errors and 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 or trading counterparties. It is not possible to identify all of the operational risks that may affect the Fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. The Fund and its shareholders could be negatively impacted as a result.

Valuation Risk. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade

Western Asset High Yield Opportunity Fund Inc.

91

Summary of information regarding the Fund (unaudited) (cont’d)

in thin or volatile markets or that are valued using a fair value methodology. These differences may increase significantly and affect Fund investments more broadly during periods of market volatility. The Fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the Fund’s investments involves subjective judgment.

Tax Risks. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, the Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy certain distribution and asset diversification requirements. If for any taxable year the Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to stockholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current or accumulated earnings and profits.

Cybersecurity Risk. Like other funds and business enterprises, the Fund, the Manager, Western Asset, the relevant listing exchange and their service providers are subject to the risk of cybersecurity incidents occurring from time to time. Cybersecurity incidents, whether intentionally caused by third parties or otherwise, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private stockholder information) or proprietary information, cause the Fund, the Manager, Western Asset, the relevant listing exchange and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. The Fund, Western Asset, and the subadvisers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the Manager. Cybersecurity incidents may result in financial losses to the Fund and its stockholders, and substantial costs may be incurred in order to prevent any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

New ways to carry out cyber attacks continue to develop. There is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund’s ability to plan for or respond to a cyber attack.

Dividend reinvestment plan (unaudited)

Unless you elect to receive distributions in cash (i.e., opt-out), all dividends, including any capital gain dividends and return of capital distributions, on your Common Stock will be automatically reinvested by Computershare Trust Company, N.A., as agent for the stock- holders (the “Plan Agent”), in additional shares of Common Stock under the Fund’s Dividend Reinvestment Plan (the “Plan”). You may elect not to participate in the Plan by contacting the Plan Agent. If you do not participate, you will receive all cash distributions paid by check mailed directly to you by Computershare Trust Company, N.A., as dividend paying agent.

If you participate in the Plan, the number of shares of Common Stock you will receive will be determined as follows:

(1) If the market price of the Common Stock (plus $0.03 per share commission) on the payment date (or, if the payment date is not a NYSE trading day, the immediately preceding trading day) is equal to or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date, the Fund will issue new Common Stock at a price equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the payment date or (b) 95% of the market price per share of the Common Stock on the payment date.

(2) If the net asset value per share of the Common Stock exceeds the market price of the Common Stock (plus $0.03 per share commission) at the close of trading on the NYSE on the payment date, the Plan Agent will receive the dividend or distribution in cash and will buy Common Stock in the open market, on the NYSE or elsewhere, for your account as soon as practicable commencing on the trading day following the payment date and terminating no later than the earlier of (a) 30 days after the dividend or distribution payment date, or (b) the payment date for the next succeeding dividend or distribution to be made to the stockholders; except when necessary to comply with applicable provisions of the federal securities laws. If during this period: (i) the market price (plus $0.03 per share commission) rises so that it equals or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date before the Plan Agent has completed the open market purchases or (ii) if the Plan Agent is unable to invest the full amount eligible to be reinvested in open market purchases, the Plan Agent will cease purchasing Common Stock in the open market and the Fund shall issue the remaining Common Stock at a price per share equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the day prior to the issuance of shares for reinvestment or (b) 95% of the then current market price per share.

Common Stock in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all shares of Common Stock you have received under the Plan. You may withdraw from the Plan (i.e., opt-out) by notifying the Plan Agent in writing at P.O. Box 43006, Providence, RI 02940-3078 or by calling the Plan Agent at 1-888-888-0151. Such withdrawal will be effective immediately if notice is received by the Plan Agent not less than ten business days prior to any dividend or distribution record date; otherwise such

94

Western Asset High Yield Opportunity Fund Inc.

withdrawal will be effective as soon as practicable after the Plan Agent’s investment of the most recently declared dividend or distribution on the Common Stock.

Plan participants who sell their shares will be charged a service charge (currently $5.00 per transaction) and the Plan Agent is authorized to deduct brokerage charges actually incurred from the proceeds (currently $0.05 per share commission). There is no service charge for reinvestment of your dividends or distributions in Common Stock. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. Because all dividends and distributions will be automatically reinvested in additional shares of Common Stock, this allows you to add to your investment through dollar cost averaging, which may lower the average cost of your Common Stock over time. Dollar cost averaging is a technique for lowering the average cost per share over time if the Fund’s net asset value declines. While dollar cost averaging has definite advantages, it cannot assure profit or protect against loss in declining markets.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Investors will be subject to income tax on amounts reinvested under the Plan.

The Fund reserves the right to amend or terminate the Plan if, in the judgment of the Board of Directors, the change is warranted. The Plan may be terminated, amended or supplemented by the Fund upon notice in writing mailed to stockholders at least 30 days prior to the record date for the payment of any dividend or distribution by the Fund for which the termination or amendment is to be effective. Upon any termination, you will be sent cash for any fractional share of Common Stock in your account. You may elect to notify the Plan Agent in advance of such termination to have the Plan Agent sell part or all of your Common Stock on your behalf. Additional information about the Plan and your account may be obtained from the Plan Agent at P.O. Box 43006, Providence, RI 02940-3078 or by calling the Plan Agent at 1-888-888-0151.

(a) Audit Fees. The aggregate fees billed in the last two fiscal years ending May 31, 2025 and May 31, 2026 (the “Reporting Periods”) for professional services rendered by the Registrant’s principal accountant (the “Auditor”) for the audit of the Registrant’s annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $50,038 in May 31, 2025 and $50,538 in May 31, 2026.

(b) Audit-Related Fees. The aggregate fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant’s financial statements were $0 in May 31, 2025 and $0 in May 31, 2026.

(c) Tax Fees. The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning (“Tax Services”) were $10,000 in May 31, 2025 and $10,000 in May 31, 2026. These services consisted of (i) review or preparation of U.S. federal, state, local and excise tax returns; (ii) U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments, and (iii) tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

There were no fees billed for tax services by the Auditors to the Registrant’s investment manager and any entity controlling, controlled by, or under common control with the investment manager that provides ongoing services to the Registrant (“Service Affiliates”) during the Reporting Periods that required pre-approval by the Audit Committee.

d) All Other Fees. The aggregate fees billed in the Reporting Periods for products and services provided by the Auditor to the Registrant, other than the services reported in paragraphs (a) through (c) of this item, were $0 in May 31, 2025 and $0 in May 31, 2026.

There were no other non-audit services rendered by the Auditor to the Service Affiliates requiring pre-approval by the Audit Committee in the Reporting Periods.

(e) Audit Committee’s pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by the Registrant’s investment manager or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“Covered Service Providers”) if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and the Covered Service Providers constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) Non-audit fees billed by the Auditor for services rendered to the Registrant and the Service Affiliates during the reporting period were $334,889 in May 31, 2025 and $344,935 in May 31, 2026.

(h) Yes. The Registrant’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Auditor’s independence. All services provided by the Auditor to the Registrant or to the Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

(j) Not applicable.

Western Asset Management Company, LLC

Proxy Voting Policies and Procedures

NOTE

The policy below relating to proxy voting and corporate actions is a global policy for Western Asset Management Company, LLC (“Western Asset” or the “Firm”) and all Western Asset affiliates, including Western Asset Management Company Limited (“Western Asset Limited”), and Western Asset Management Company Pte. Ltd. (“Western Asset Singapore”), as applicable. As compliance with the policy is monitored by Western Asset, the policy has been adopted from the US Compliance Manual and all defined terms are those defined in the US Compliance Manual rather than the compliance manual of any other Western Asset affiliate.

BACKGROUND

An investment adviser is required to adopt and implement policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with fiduciary duties and Rule 206(4)-6 under the Investment Advisers Act of 1940 (“Advisers Act”). The authority to vote the proxies of our clients is established through investment management agreements or comparable documents. In addition to SEC requirements governing advisers, long-standing fiduciary standards and responsibilities have been established for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the investment manager.

POLICY

As a fixed income only manager, the occasion to vote proxies is very rare, for instance, when fixed income securities are converted into equity by their terms or in connection with a bankruptcy or corporate workout. However, the Firm has adopted and implemented policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with our fiduciary duties and Rule 206(4)-6 under the Advisers Act. In addition to SEC requirements governing advisers, our proxy voting policies reflect the long-standing fiduciary standards and responsibilities for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the investment manager.

While the guidelines included in the procedures are intended to provide a benchmark for voting standards, each vote is ultimately cast on a case-by-case basis, taking into consideration the Firm’s contractual obligations to our clients and all other relevant facts and circumstances at the time of the vote (such that these guidelines may be overridden to the extent the Firm deems appropriate).

In exercising its voting authority, Western Asset will not consult or enter into agreements with officers, directors or employees of Franklin Resources (Franklin Resources includes Franklin Resources, Inc. and organizations operating as Franklin Resources) or any of its affiliates (other than Western Asset affiliated companies) regarding the voting of any securities owned by its clients.

PROCEDURES

Responsibility and Oversight

The Legal & Compliance Group is responsible for administering and overseeing the proxy voting process. The gathering of proxies is coordinated through the Corporate Actions team of the Investment Operations Group (“Corporate Actions”). Research analysts and portfolio managers are responsible for determining appropriate voting positions on each proxy utilizing any applicable guidelines contained in these procedures.

Client Authority

The Investment Management Agreement for each client is reviewed at account start-up for proxy voting instructions. If an agreement is silent on proxy voting, but contains an overall delegation of discretionary authority or if the account represents assets of an ERISA plan, Western Asset will assume responsibility for proxy voting. The Portfolio Compliance Group maintains a matrix of proxy voting authority.

Proxy Gathering

Registered owners of record, client custodians, client banks and trustees (“Proxy Recipients”) that receive proxy materials on behalf of clients should forward them to Corporate Actions. Proxy Recipients for new clients (or, if Western Asset becomes aware that the applicable Proxy Recipient for an existing client has changed, the Proxy Recipient for the existing client) are notified at start-up of appropriate routing to Corporate Actions of proxy materials received and reminded of their responsibility to forward all proxy materials on a timely basis. If Western Asset personnel other than Corporate Actions receive proxy materials, they should promptly forward the materials to Corporate Actions.

Proxy Voting

Once proxy materials are received by Corporate Actions, they are forwarded to the Portfolio Compliance Group for coordination and the following actions:

Proxies are reviewed to determine accounts impacted.

Impacted accounts are checked to confirm Western Asset voting authority.

Where appropriate, the Regulatory Affairs Group reviews the issues presented to determine any material conflicts of interest. (See Conflicts of Interest section of these procedures for further information on determining material conflicts of interest.)

If a material conflict of interest exists, (i) to the extent reasonably practicable and permitted by applicable law, the client is promptly notified, the conflict is disclosed and Western Asset obtains the client’s proxy voting instructions, and (ii) to the extent that it is not reasonably practicable or permitted by applicable law to notify the client and obtain such instructions (e.g., the client is a mutual fund or other commingled vehicle or is an ERISA plan client), Western Asset seeks voting instructions from an independent third party.

The Portfolio Compliance Group provides proxy material to the appropriate research analyst or portfolio manager to obtain their recommended vote. Research analysts and portfolio managers determine votes on a case-by-case basis taking into account the voting guidelines contained in these procedures. For avoidance of doubt, depending on the best interest of each individual client, Western Asset may vote the same proxy differently for different clients. The analyst’s or portfolio manager’s basis for their decision is documented and maintained by the Portfolio Compliance Group.

Portfolio Compliance Group votes the proxy pursuant to the instructions received in (d) or (e) and returns the voted proxy as indicated in the proxy materials.

Timing

Western Asset’s Legal and Compliance Department personnel act in such a manner to ensure that, absent special circumstances, the proxy gathering and proxy voting steps noted above can be completed before the applicable deadline for returning proxy votes.

Recordkeeping

Western Asset maintains records of proxies voted pursuant to Rule 204-2 of the Advisers Act and ERISA DOL Bulletin 94-2. These records include:

• A copy of Western Asset’s proxy voting policies and procedures.

• Copies of proxy statements received with respect to securities in client accounts.

• A copy of any document created by Western Asset that was material to making a decision how to vote proxies.

• Each written client request for proxy voting records and Western Asset’s written response to both verbal and written client requests.

A proxy log including:

1. Issuer name;

2. Exchange ticker symbol of the issuer’s shares to be voted;

3. Committee on Uniform Securities Identification Procedures (“CUSIP”) number for the shares to be voted;

4. A brief identification of the matter voted on;

5. Whether the matter was proposed by the issuer or by a shareholder of the issuer;

6. Whether a vote was cast on the matter;

7. A record of how the vote was cast;

8. Whether the vote was cast for or against the recommendation of the issuer’s management team;

9. Funds are required to categorize their votes so that investors can focus on the topics they find important. Categories include, for example, votes related to director elections, extraordinary transactions, say-on-pay, shareholder rights and defenses, and the environment or climate, among others; and

10. Funds are required to disclose the number of shares voted or instructed to be cast, as well as the number of shares loaned but not recalled and, therefore, not voted by the fund.

Records are maintained in an easily accessible place for a period of not less than five (5) years with the first two (2) years in Western Asset’s offices.

Disclosure

Western Asset’s proxy policies and procedures are described in the Firm’s Form ADV Part 2A. Clients are provided with a copy of these policies and procedures upon request. In addition, clients may receive reports on how their proxies have been voted, upon request.

Conflicts of Interest

All proxies that potentially present conflicts of interest are reviewed by the Regulatory Affairs Group for a materiality assessment. Issues to be reviewed include, but are not limited to:

1. Whether Western Asset (or, to the extent required to be considered by applicable law, its affiliates) manages assets for the company or an employee group of the company or otherwise has an interest in the company;

2. Whether Western Asset or an officer or director of Western Asset or the applicable portfolio manager or analyst responsible for recommending the proxy vote (together, “Voting Persons”) is a close relative of or has a personal or business relationship with an executive, director or person who is a candidate for director of the company or is a participant in a proxy contest; and

3. Whether there is any other business or personal relationship where a Voting Person has a personal interest in the outcome of the matter before shareholders.

Voting Guidelines

Western Asset’s substantive voting decisions are based on the particular facts and circumstances of each proxy vote and are evaluated by the designated research analyst or portfolio manager. The examples outlined below are meant as guidelines to aid in the decision making process.

Situations can arise in which more than one Western Asset client invests in instruments of the same issuer or in which a single client may invest in instruments of the same issuer but in multiple accounts or strategies. Multiple clients or the same client in multiple accounts or strategies may have different investment objectives, investment styles, or investment professionals involved in making decisions. While there may be differences, votes are always cast in the best interests of the client and the investment objectives agreed with Western Asset. As a result, there may be circumstances where Western Asset casts different votes on behalf of different clients or on behalf of the same client with multiple accounts or strategies.

Guidelines are grouped according to the types of proposals generally presented to shareholders. Part I deals with proposals which have been approved and are recommended by a company’s board of directors; Part II deals with proposals submitted by shareholders for inclusion in proxy statements; Part III addresses issues relating to voting shares of investment companies; and Part IV addresses unique considerations pertaining to foreign issuers.

I. Board Approved Proposals

The vast majority of matters presented to shareholders for a vote involve proposals made by a company itself that have been approved and recommended by its board of directors. In view of the enhanced corporate governance practices currently being implemented in public companies, Western Asset generally votes in support of decisions reached by independent boards of directors. More specific guidelines related to certain board-approved proposals are as follows:

1. Matters relating to the Board of Directors

Western Asset votes proxies for the election of the company’s nominees for directors and for board-approved proposals on other matters relating to the board of directors with the following exceptions:

a. Votes are withheld for the entire board of directors if the board does not have a majority of independent directors or the board does not have nominating, audit and compensation committees composed solely of independent directors.

b. Votes are withheld for any nominee for director who is considered an independent director by the company and who has received compensation from the company other than for service as a director.

c. Votes are withheld for any nominee for director who attends less than 75% of board and committee meetings without valid reasons for absences.

d. Votes are cast on a case-by-case basis in contested elections of directors.

2. Matters relating to Executive Compensation

Western Asset generally favors compensation programs that relate executive compensation to a company’s long-term performance. Votes are cast on a case-by-case basis on board-approved proposals relating to executive compensation, except as follows:

a. Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for stock option plans that will result in a minimal annual dilution.

b. Western Asset votes against stock option plans or proposals that permit replacing or repricing of underwater options.

c. Western Asset votes against stock option plans that permit issuance of options with an exercise price below the stock’s current market price.

d. Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for employee stock purchase plans that limit the discount for shares purchased under the plan to no more than 15% of their market value, have an offering period of 27 months or less and result in dilution of 10% or less.

3. Matters relating to Capitalization

The Management of a company’s capital structure involves a number of important issues, including cash flows, financing needs and market conditions that are unique to the circumstances of each company. As a result, Western Asset votes on a case-by-case basis on board-approved proposals involving changes to a company’s capitalization except where Western Asset is otherwise withholding votes for the entire board of directors.

a. Western Asset votes for proposals relating to the authorization of additional common stock.

b. Western Asset votes for proposals to effect stock splits (excluding reverse stock splits).

c. Western Asset votes for proposals authorizing share repurchase programs.

4. Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions

Western Asset votes these issues on a case-by-case basis on board-approved transactions.

5. Matters relating to Anti-Takeover Measures

Western Asset votes against board-approved proposals to adopt anti-takeover measures except as follows:

a. Western Asset votes on a case-by-case basis on proposals to ratify or approve shareholder rights plans.

b. Western Asset votes on a case-by-case basis on proposals to adopt fair price provisions.

6. Other Business Matters

Western Asset votes for board-approved proposals approving such routine business matters such as changing the company’s name, ratifying the appointment of auditors and procedural matters relating to the shareholder meeting.

a. Western Asset votes on a case-by-case basis on proposals to amend a company’s charter or bylaws.

b. Western Asset votes against authorization to transact other unidentified, substantive business at the meeting.

7. Reporting of Financially Material Information

Western Asset generally believes issuers should disclose information that is material to their business.

What qualifies as “material” can vary, so votes are cast on a case-by-case basis but consistent with the overarching principle.

II. Shareholder Proposals

SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy statement. These proposals generally seek to change some aspect of a company’s corporate governance structure or to change some aspect of its business operations. Western Asset votes in accordance with the recommendation of the company’s board of directors on all shareholder proposals, except as follows:

1. Western Asset votes for shareholder proposals to require shareholder approval of shareholder rights plans.

2. Western Asset votes for shareholder proposals that are consistent with Western Asset’s proxy voting guidelines for board-approved proposals.

3. Western Asset votes on a case-by-case basis on other shareholder proposals where the firm is otherwise withholding votes for the entire board of directors.

Environmental or social issues that are the subject of a proxy vote will be considered on a case-by-case basis. Constructive proposals that seek to advance the health of the issuer and the prospect for risk-adjusted returns to Western Assets clients are viewed more favorably than proposals that advance a single issue or limit the ability of management to meet its operating objectives.

III. Voting Shares of Investment Companies

Western Asset may utilize shares of open or closed-end investment companies to implement its investment strategies. Shareholder votes for investment companies that fall within the categories listed in Parts I and II above are voted in accordance with those guidelines.

1. Western Asset votes on a case-by-case basis on proposals relating to changes in the investment objectives of an investment company taking into account the original intent of the fund and the role the fund plays in the clients’ portfolios.

2. Western Asset votes on a case-by-case basis all proposals that would result in increases in expenses (e.g., proposals to adopt 12b-1 plans, alter investment advisory arrangements or approve fund mergers) taking into account comparable expenses for similar funds and the services to be provided.

IV. Voting Shares of Foreign Issuers

In the event Western Asset is required to vote on securities held in non-U.S. issuers – i.e. issuers that are incorporated under the laws of a foreign jurisdiction and that are not listed on a U.S. securities exchange or the NASDAQ stock market, the following guidelines are used, which are premised on the existence of a sound corporate governance and disclosure framework. These guidelines, however, may not be appropriate under some circumstances for foreign issuers and therefore apply only where applicable.

1. Western Asset votes for shareholder proposals calling for a majority of the directors to be independent of management.

2. Western Asset votes for shareholder proposals seeking to increase the independence of board nominating, audit and compensation committees.

3. Western Asset votes for shareholder proposals that implement corporate governance standards similar to those established under U.S. federal law and the listing requirements of U.S. stock exchanges, and that do not otherwise violate the laws of the jurisdiction under which the company is incorporated.

4. Western Asset votes on a case-by-case basis on proposals relating to (1) the issuance of common stock in excess of 20% of a company’s outstanding common stock where shareholders do not have preemptive rights, or (2) the issuance of common stock in excess of 100% of a company’s outstanding common stock where shareholders have preemptive rights.

V. Environmental, Social and Governance (“ESG”) Matters

Western Asset incorporates ESG considerations, among other relevant risks, as part of the overall process where appropriate. The Firm seeks to identify and consider material risks to the investment thesis, including material risks presented by ESG factors. While Western Asset is primarily a fixed income manager, opportunities to vote proxies are considered on the investment merits of the instruments and strategies involved.

As a general proposition, Western Asset votes to encourage disclosure of information material to their business. This principle extends to ESG matters. What qualifies as “material” can vary, so votes are cast on a case-by-case basis but consistent with the overarching principle. Western Asset recognizes that objective standards and criteria may not be available or universally agreed and that there may be different views and subjective analysis regarding factors and their significance.

Targeted environmental or social issues that are the subject of a proxy vote will be considered on a case-by-case basis. Constructive proposals that seek to advance the health of the issuer and the prospect for risk-adjusted returns to Western Assets clients are viewed more favorably than proposals that advance a single issue or limit the ability of management to meet its operating objectives.

Retirement Accounts

For accounts subject to ERISA, as well as other retirement accounts, Western Asset is presumed to have the responsibility to vote proxies for the client. The Department of Labor has issued a bulletin that states that investment managers have the responsibility to vote proxies on behalf of Retirement Accounts unless the authority to vote proxies has been specifically reserved to another named fiduciary. Furthermore, unless Western Asset is expressly precluded from voting the proxies, the Department of Labor has determined that the responsibility remains with the investment manager.

In order to comply with the Department of Labor’s position, Western Asset will be presumed to have the obligation to vote proxies for its retirement accounts unless Western Asset has obtained a specific written instruction indicating that: (a) the right to vote proxies has been reserved to a named fiduciary of the client, and (b) Western Asset is precluded from voting proxies on behalf of the client. If Western Asset does not receive such an instruction, Western Asset will be responsible for voting proxies in the best interests of the retirement account client and in accordance with any proxy voting guidelines provided by the client.

(a)(3): Portfolio Manager Compensation (As of May 31, 2026):

Investment Professional Compensation

Conflicts of Interest

The Subadviser has adopted compliance policies and procedures to address a wide range of potential conflicts of interest that could directly impact client portfolios. For example, potential conflicts of interest may arise in connection with the management of multiple portfolios (including portfolios managed in a personal capacity). These could include potential conflicts of interest related to the knowledge and timing of a portfolio’s trades, investment opportunities and broker selection. Portfolio managers are privy to the size, timing, and possible market impact of a portfolio’s trades.

It is possible that an investment opportunity may be suitable for both a portfolio and other accounts managed by a portfolio manager, but may not be available in sufficient quantities for both the portfolio and the other accounts to participate fully. Similarly, there may be limited opportunity to sell an investment held by a portfolio and another account. A conflict may arise where the portfolio manager may have an incentive to treat an account preferentially as compared to a portfolio because the account pays a performance-based fee or the portfolio manager, the Subadviser or an affiliate has an interest in the account. The Subadviser has adopted procedures for allocation of portfolio transactions and investment opportunities across multiple client accounts on a fair and equitable basis over time. Eligible accounts that can participate in a trade generally share the same price on a pro-rata allocation basis, taking into account differences based on factors such as cash availability, investment restrictions and guidelines, and portfolio composition versus strategy.

With respect to securities transactions, the Subadviser determines which broker or dealer to use to execute each order, consistent with their duty to seek best execution of the transaction. However, with respect to certain other accounts (such as pooled investment vehicles that are not registered investment companies and other accounts managed for organizations and individuals), the Subadviser may be limited by the client with respect to the selection of brokers or dealers or may be instructed to direct trades through a particular broker or dealer. In these cases, trades for a portfolio in a particular security may be placed separately from, rather than aggregated with, such other accounts. Having separate transactions with respect to a security may temporarily affect the market price of the security or the execution of the transaction, or both, to the possible detriment of a portfolio or the other account(s) involved. Additionally, the management of multiple portfolios and/or other accounts may result in a portfolio manager devoting unequal time and attention to the management of each portfolio and/or other account. The Subadviser’s team approach to portfolio management and block trading approach seeks to limit this potential risk.

The Subadviser also maintains a gift and entertainment policy to address the potential for a business contact to give gifts or host entertainment events that may influence the business judgment of an employee. Employees are permitted to retain gifts of only a nominal value and are required to make reimbursement for entertainment events above a certain value. All gifts (except those of a de minimis value) and entertainment events that are given or sponsored by a business contact are required to be reported in a gift and entertainment log which is reviewed on a regular basis for possible issues.

Employees of the Subadviser have access to transactions and holdings information regarding client accounts and the Subadviser’s overall trading activities. This information represents a potential conflict of interest because employees may take advantage of this information as they trade in their personal accounts. Accordingly, the Subadviser maintains a Code of Ethics that is compliant with Rule 17j-1 under the 1940 Act and Rule 204A-1 under the Advisers Act to address personal trading. In addition, the Code of Ethics seeks to establish broader principles of good conduct and fiduciary responsibility in all aspects of the Subadviser’s business. The Code of Ethics is administered by the Legal and Compliance Department and monitored through the Subadviser’s compliance monitoring program.

The Subadviser may also face other potential conflicts of interest with respect to managing client assets, and the description above is not a complete description of every conflict of interest that could be deemed to exist. The Subadviser also maintains a compliance monitoring program and engages independent auditors to conduct a SOC1/ISAE 3402 audit on an annual basis. These steps help to ensure that potential conflicts of interest have been addressed.

Investment Professional Compensation

With respect to the compensation of the Fund’s investment professionals, the Subadviser’s compensation system assigns each employee a total compensation range, which is derived from annual market surveys that benchmark each role with its job function and peer universe. This method is designed to reward employees with total compensation reflective of the external market value of their skills, experience and ability to produce desired results. Standard compensation includes competitive base salaries, generous employee benefits and a retirement plan.

In addition, the Subadviser’s employees are eligible for bonuses. These are structured to closely align the interests of employees with those of the Subadviser, and are determined by the professional’s job function and pre-tax performance as measured by a formal review process. All bonuses are completely discretionary. The principal factor considered is an investment professional’s investment performance versus appropriate peer groups and benchmarks (e.g., a securities index and with respect to the Fund, the benchmark set forth in the Fund’s Prospectus to which the Fund’s average annual total returns are compared or, if none, the benchmark set forth in the Fund’s annual report). Performance is reviewed on a 1, 3 and 5 year basis for compensation—with 3 and 5 years having a larger emphasis. The Subadviser may also measure an investment professional’s pre-tax investment performance against other benchmarks, as it determines appropriate. Because investment professionals are generally responsible for multiple accounts (including the Fund) with similar investment strategies, they are generally compensated on the performance of the aggregate group of similar accounts, rather than a specific account. Other factors that may be considered when making bonus decisions include client service, business development, length of service to the Subadviser, management or supervisory responsibilities, contributions to developing business strategy and overall contributions to the Subadviser’s business.

Finally, in order to attract and retain top talent, all investment professionals are eligible for additional incentives in recognition of outstanding performance. These are determined based upon the factors described above and include long-term incentives that vest over a set period of time past the award date.
