Performance Overview

WHAT IS THE FUND’S INVESTMENT STRATEGY?

The RiverNorth/DoubleLine Strategic Opportunity Fund (“the Fund”) seeks to achieve its investment objective by allocating its Managed Assets among the three principal investment strategies described below:

Tactical Closed-End Fund Income Strategy: This strategy seeks to (i) generate returns through investments in closed-end funds, special purpose acquisition companies ("SPACs"), exchange-traded funds and business development companies (collectively, the “Underlying Funds”) that invest primarily in income-producing securities, and (ii) derive value from the discount and premium spreads associated with closed-end funds.

Opportunistic Income Strategy: This strategy seeks to generate attractive risk-adjusted returns through investments in fixed income instruments and other investments, including agency and non-agency residential mortgage-backed and other asset-backed securities, corporate bonds, municipal bonds, and real estate investment trusts. At least 50% of the Managed Assets allocated to this strategy is invested in mortgage-backed securities.

Alternative Credit Strategy: This strategy seeks to achieve a high level of income by investing in alternative credit instruments. The Fund's alternative credit investments may be made through a combination of: (i) investing in loans to small and mid-sized companies (“SMEs”); (ii) investing in notes or other pass-through obligations issued by an alternative credit platform (or an affiliate) representing the right to receive the principal and interest payments on an alternative credit investment (or fractional portions thereof) originated through the platform (“Pass-Through Notes”); (iii) purchasing asset-backed securities representing ownership in a pool of alternative credit; (iv) investing in private investment funds that purchase Alternative Credit; (v) acquiring an equity interest in an alternative credit platform (or an affiliate); and (vi) providing loans, credit lines or other extensions of credit to an alternative credit platform (or an affiliate). The Fund may invest in income-producing securities of any maturity and credit quality, including unrated or below investment grade.

RiverNorth Capital Management, LLC (“RiverNorth” or the "Adviser") allocates the Fund’s Managed Assets among three principal strategies. RiverNorth manages the Tactical CEF Income Strategy and the Alternative Credit Strategy, DoubleLine Capital, LP ("DoubleLine") manages the Opportunistic Income Strategy.

RiverNorth determines which portion of the Fund’s assets is allocated to each strategy based on market conditions.

Performance returns are net of management fees and other Fund expenses.

⁽⁴⁾

⁽⁵⁾

The Bloomberg U.S. Aggregate Bond Index is an unmanaged index of investment grade fixed-rate debt issues with maturities of at least one year. The index cannot be invested in directly and does not reflect fees and expenses.

The total annual expense ratio as a percentage of net assets attributable to common shares as of December 31, 2024 is 2.06% (excluding interest on facility loan payable). Including interest on facility loan payable, the expense ratio is 2.65%.

Performance data quoted represents past performance, which is not a guarantee of future results. Current performance may be lower or higher than the performance quoted. The principal value and investment return of an investment will fluctuate so that your shares may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling (844) 569-4750. Total return measures net investment income and capital gain or loss from portfolio investments. All performance shown assumes reinvestment of dividends and capital gains distributions but does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares.

Semi-Annual Report | December 31, 2024

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc.

Financial Highlights

For a common share outstanding throughout the periods presented

^(a)

Based on average shares outstanding during the period.

^(b)

Recognition of net investment income by the Fund is affected by the timing of the declarations of dividends by the underlying closed-end funds in which the Fund invests. The ratio does not include net investment income of the closed-end funds in which the Fund invests.

^(c)

Calculated using the average shares method.

^(d)

Represents the impact of the Fund's rights offering of 838,412 shares in November 2024, 3,508,633 shares in September 2022, 2,926,441 shares in October 2021, 472,995 shares in October 2020, and 2,371,081 shares in December 2019 at a subscription price per share based on a formula. For more details please refer to Note 10 of the Notes to Financial Statements.

^(e)

Less than $0.005 per share.

^(f)

Total investment return is calculated assuming a purchase of common shares at the opening on the first day and a sale at closing on the last day of each period reported. For purposes of this calculation, dividends and distributions, if any, are assumed to be reinvested at prices obtained under the Fund’s dividend reinvestment plan. Total investment returns do not reflect brokerage commissions, if any. Total return on Market Price does not reflect any sales load paid by investors. Periods less than one year are not annualized.

^(g)

Not annualized.

^(h)

Ratio includes leverage expenses and loan service fees of 0.59%, 0.00%, 0.05%, 0.21% and 0.91%, respectively, that are outside the expense limit.

⁽ⁱ⁾

Does not include expenses of the closed-end funds in which the Fund invests.

^(j)

Annualized.

^(k)

Calculated by subtracting the Fund's total liabilities (excluding the debt balance and accumulated unpaid interest) from the Fund's total assets and dividing by the outstanding debt balance.

^(l)

The asset coverage ratio for a class of senior securities representing stock is calculated as the Fund's total assets, less all liabilities and indebtedness not represented by the Fund's senior securities, divided by secured senior securities representing indebtedness plus the aggregate of the involuntary liquidation preference of secured senior securities which are stock. The involuntary liquidation preference of a class of senior security, which is a stock, is the amount to which such class of senior security would be entitled on involuntary liquidation of the issuer in preference to a security junior to it. Series B Perpetual Preferred Stock and Series C Term Preferred Stock have the same priority with respect to payment of dividends and distributions and liquidation preference as the issued and outstanding Series A Preferred Stock and any other shares of preferred stock that the Fund may issue. With respect to the Series A Perpetual Preferred Stock, Series B Perpetual Preferred Stock and Series C Term Preferred Stock, the asset coverage per unit figure is expressed in terms of dollar amounts per share of outstanding Preferred Stock (based on a liquidation preference of $25 for Series A and Series B Preferred Stock, and a liquidation of $10 for Series C Preferred Stock) and is equivalent to the Asset Coverage of Preferred Stock presented given Series A, Series B and Series C Preferred Stock have a pari-passu liquidation preference.

1. ORGANIZATION

RiverNorth/DoubleLine Strategic Opportunity Fund, Inc. (the “Fund”) is a closed-end management investment company that was organized as a Maryland corporation on June 22, 2016, and commenced investment operations on September 28, 2016. The investment adviser to the Fund is RiverNorth Capital Management, LLC (the “Adviser”). The Fund’s sub-adviser is DoubleLine Capital, LP (“Sub-Adviser”). The Fund is a diversified investment company with an investment objective to seek current income and overall total return.

The Fund seeks to achieve its investment objective by allocating its Managed Assets among three principal strategies: Tactical Closed End Fund Income Strategy, Alternative Credit Strategy and Opportunistic Income Strategy. The Adviser will determine the portion of the Fund’s Managed Assets to allocate to each strategy and may, from time to time, adjust the allocations.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Fund. These policies are in conformity with generally accepted accounting principles in the United States of America (“GAAP”). The financial statements are prepared in accordance with GAAP, which requires management to make estimates and assumptions that affect the reported amounts and disclosures, including the disclosure of contingent assets and liabilities, in the financial statements during the reporting period. Management believes the estimates and security valuations are appropriate; however, actual results may differ from those estimates, and the security valuations reflected in the financial statements may differ from the value the Fund ultimately realizes upon sale of the securities. The Fund is considered an investment company for financial reporting purposes under GAAP and follows the accounting and reporting guidance applicable to investment companies as codified in Accounting Standards Codification (“ASC”) Topic 946 – Financial Services – Investment Companies. The financial statements have been prepared as of the close of the New York Stock Exchange (“NYSE”) on December 31, 2024.

Security Valuation: The Fund’s investments are generally valued at their fair value using market quotations. If a market value quotation is unavailable a security may be valued at its estimated fair value as described in Note 3.

Security Transactions and Related Income: The Fund follows industry practice and records security transactions on the trade date basis. The specific identification method is used for determining gains or losses for financial statements and income tax purposes. Dividend income is recorded on the ex-dividend date or for certain foreign securities, when the information becomes available to the Fund and interest income and expenses are recorded on an accrual basis. Discounts and premiums on securities purchased are amortized or accreted using the effective interest method. Paydown gains and losses on mortgage-related and other asset-backed securities are recorded as components of interest income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. The ability of issuers of debt securities held by the Fund to meet their obligations may be affected by economic and political developments in a specific country or region. Settlement on bank loans transactions may be in excess of seven business days. Interest only stripped mortgage backed securities (“IO Strips”) are securities that receive only interest payments from a pool of mortgage loans. Little to no principal will be received by the Fund upon maturity of an IO Strip. Periodic adjustments are recorded to reduce the cost of the security until maturity, which are included in interest income.

Notes to Financial Statements

December 31, 2024 (Unaudited)

Foreign Currency Translation: The books and records of the Fund are maintained in U.S. dollars. Investment valuations and other assets and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Prevailing foreign exchange rates may generally be obtained at the close of the NYSE (normally, 4:00 p.m. Eastern Time). The portion of realized and unrealized gains or losses on investments due to fluctuations in foreign currency exchange rates is not separately disclosed and is included in realized and unrealized gains or losses on investments, when applicable.

Cash Balance: The Fund places its cash on deposit with financial institutions in the United States, which are insured by the Federal Deposit Insurance Corporation ("FDIC") up to $250,000. The Fund's credit risk in the event of failure of these financial institutions is represented by the difference between the FDIC limit and the total amounts on deposit. Management monitors the financial institutions' creditworthiness in conjunction with balances on deposit to minimize risk. The Fund from time to time may have amounts on deposit in excess of the insured limits.

Preferred Stock: In accordance with ASC 480-10-25, the Fund's Series A and Series B Cumulative Perpetual Preferred Stock have been classified as equity on the Statement of Assets and Liabilities. Refer to "Note 9. Preferred Stock" for further details.

Other: The Fund holds certain investments which pay dividends to their shareholders based upon available funds from operations. It is possible for these dividends to exceed the underlying investments’ taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. Distributions received from investments in securities that represent a return of capital or long-term capital gains are recorded as a reduction of the cost of investments or as a realized gain, respectively.

The Fund invests in closed-end funds, each of which has its own investment risks. Those risks can affect the value of the Fund's investments and therefore the value of the Fund's shares. To the extent that the Fund invests more of its assets in one closed end fund than in another, the Fund will have greater exposure to the risks of that closed end fund.

Common Share Valuation: The NAV is generally calculated as of the close of trading on the NYSE (normally 4:00 p.m. Eastern Time) every day the NYSE is open. The NAV is calculated by dividing the value of all of the securities and other assets of the Fund, less the liabilities (including accrued expenses and indebtedness), by the total number of common shares outstanding.

Federal Income Taxes: The Fund has been treated as, and intends to qualify each year for special tax treatment afforded to, a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“IRC”). In order to qualify as a RIC, the Fund must, among other things, satisfy income, asset diversification and distribution requirements. As long as it so qualifies, the Fund will not be subject to U.S. federal income tax to the extent that it distributes annually its investment company taxable income and its “net capital gain”. If the Fund retains any investment company taxable income or net capital gain, it will be subject to U.S. federal income tax on the retained amount at regular corporate tax rates. In addition, if the Fund fails to qualify as a RIC for any taxable year, it will be subject to U.S. federal income tax on all of its income and gains at regular corporate tax rates.

Notes to Financial Statements

December 31, 2024 (Unaudited)

As of and during the six months ended December 31, 2024, the Fund did not have a liability for any unrecognized tax benefits. The Fund files U.S. federal, state, and local tax returns as required. The Fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return for federal purposes and four years for most state returns. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expenses on the Statement of Operations. During the six months ended December 31, 2024, the Fund did not incur any interest or penalties.

Distributions to Shareholders: Distributions to shareholders, which are determined in accordance with income tax regulations, are recorded on the ex-dividend date. The treatment for financial reporting purposes of distributions made to common shareholders during the year from net investment income or net realized capital gains may differ from their ultimate treatment for federal income tax purposes. These differences are caused primarily by differences in the timing of recognition of certain components of income, expense, or realized capital gain for federal income tax purposes. Where such differences are permanent in nature, they are reclassified in the components of the net assets based on their ultimate characterization for federal income tax purposes. Any such reclassification will have no effect on net assets, results of operations, or net asset values (“NAV”) per common share of the Fund.

The Fund maintains a level distribution policy. The Fund distributes to common shareholders regular monthly cash distributions of its net investment income. In addition, the Fund distributes its net realized capital gains, if any, at least annually. At times, to maintain a stable level of distributions, the Fund may pay out less than all of its net investment income or pay out accumulated undistributed income, or return of capital, in addition to current net investment income. Any distribution that is treated as a return of capital generally will reduce a common shareholder’s basis in his or her shares, which may increase the capital gain or reduce the capital loss realized upon the sale of such shares. Any amounts received in excess of a common shareholder’s basis are generally treated as capital gain, assuming the shares are held as capital assets. The Board approved the implementation of the level distribution policy to make monthly cash distributions to common shareholders, stated in terms of a rate equal to 12.5% of the average of the Fund’s NAV per common share for the final five trading days of the previous calendar year. The Fund made monthly distributions to common shareholders set at a level monthly rate of $0.1003 per common share for the six months ended December 31, 2024.

Previously, the Board approved the adoption of a managed distribution plan in accordance with a Section 19(b) exemptive order whereby the Fund made monthly distributions to common shareholders set at a fixed monthly rate.

Distributions to holders of preferred stock are accrued on a daily basis as described in Note 9.

Return of Capital Distributions: At times, to maintain a stable level of distributions, the Fund may pay out less than all of its net investment income or pay out accumulated undistributed income, or return of capital, in addition to current net investment income. Any distribution that is treated as a return of capital generally will reduce a common shareholder’s basis in his or her shares, which may increase the capital gain or reduce the capital loss realized upon the sale of such shares.

3. SECURITIES VALUATION AND FAIR VALUE MEASUREMENTS

Fair value is defined as the price that the Fund might reasonably expect to receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. GAAP establishes a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes.

Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value including using such a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in the three broad levels listed below.

Level 1 –

Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Fund has the ability to access at the measurement date;

Level 2 –

Quoted prices which are not active, quoted prices for similar assets or liabilities in active markets or inputs other than quoted prices that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and

Level 3 –

Significant unobservable prices or inputs (including the Fund’s own assumptions in determining the fair value of investments) where there is little or no market activity for the asset or liability at the measurement date.

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Equity securities, including closed-end funds and business development company notes, are generally valued by using market quotations, but may be valued on the basis of prices furnished by a pricing service when the Adviser believes such prices more accurately reflect the fair market value of such securities. Securities that are traded on any stock exchange are generally valued by the pricing service at the last quoted sale price. Lacking a last sale price, an exchange traded security is generally valued by the pricing service at its last bid price. Securities traded in the NASDAQ over-the-counter market are generally valued by the pricing service at the NASDAQ Official Closing Price. When using the market quotations or close prices provided by the pricing service and when the market is considered active, the security will be classified as a Level 1 security. Sometimes, an equity security owned by the Fund will be valued by the pricing service with factors other than market quotations or when the market is considered inactive. When this happens, the security will be classified as a Level 2 security. When market quotations are not readily available, when the Adviser determines that the market quotation or the price provided by the pricing service does not accurately reflect the current fair value, or when restricted or illiquid securities are being valued, such securities are valued as determined in good faith by the Adviser, as the Fund's valuation designee, in conformity with guidelines adopted by and subject to review by the Board. These securities will be categorized as Level 3 securities.

Investments in mutual funds, including short term investments, are generally priced at the ending NAV provided by the service agent of the funds. These securities will be classified as Level 1 if the securities are determined to have a readily determinable fair value. For an investment that does not have a readily determinable fair value, the investment will be valued using the NAV reported by the investment fund as a practical expedient, without further adjustment, unless it is probable that the investment will be sold at a value significantly different than the reported NAV.

Domestic and foreign fixed income securities, including foreign and U.S. corporate bonds, foreign and U.S. government bonds, non-agency collateralized mortgage obligations, U.S. Government/ Agency mortgage backed securities, bank loans, and collateralized loan obligations are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Foreign currency positions, including forward foreign currency contracts, are priced at the mean between the closing bid and asked prices at 4:00 p.m. Eastern Time. Prices obtained from independent pricing services typically use information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Data used to establish quotes includes analysis of cash flows, pre-payment speeds, default rates, delinquency assumptions and assumptions regarding collateral and loss assumptions. These securities will be classified as Level 2 securities.

Small business loans, as an asset class, are not presently traded on a developed secondary market. Therefore, market quotations are not available. Accordingly, all small business loans are fair valued as determined in good faith by the Adviser pursuant to policies and procedures approved by the Board and subject to the Board’s oversight. The Fund's holdings in small business loans are fair valued daily by the Adviser using a discounted cash flow methodology, as an income approach. Discounted cash flow is a valuation technique that provides an estimation of the fair value of an asset based on expectations about cash flows that a small business loan would generate over time. In general, the primary inputs of fair value in the small business loan valuation model are projected loss rate and adjusted discount rate. A discounted cash flow model begins with an estimation of periodic cash flows expected to be generated over a discrete period of time (generally the time remaining until maturity of the loan). The estimated cash flows for each interval period (generally monthly) are then converted to their present value equivalent using a rate of return appropriate for the risk of achieving projected cash flows. Although not exhaustive, discounted cash flow models factor in borrower level data. Loans made to small businesses may incorporate different factors.

December 31, 2024 (Unaudited)

Short-term investments in fixed income securities, excluding money market funds, with maturities of less than 60 days when acquired, or which subsequently are within 60 days of maturity, and of sufficient credit quality, are valued by using the amortized cost method of valuation. These securities will be classified as Level 2 securities.

Effective September 8, 2022, and pursuant to the requirements of Rule 2a-5 under the 1940 Act, the Board approved updated valuation procedures for the Fund and designated the Adviser as the Fund's valuation designee to make all fair valuation determinations with respect to the Fund's portfolio investments, subject to the Board's oversight.

In accordance with the Fund’s good faith pricing guidelines, the Adviser is required to consider all appropriate factors relevant to the value of securities for which it has determined other pricing sources are not available or reliable as described above. No single standard exists for determining fair value, because fair value depends upon the circumstances of each individual case. As a general principle, the current fair value of an issue of securities being valued by the Adviser would appear to be the amount which the owner might reasonably expect to receive for them upon their current sale. Methods which are in accordance with this principle may, for example, be based on (i) a multiple of earnings; (ii) discounted cash flow models; (iii) weighted average cost or weighted average price; (iv) a discount from market of a similar freely traded security (including a derivative security or a basket of securities traded on other markets, exchanges or among dealers); or (v) yield to maturity with respect to debt issues, or a combination of these and other methods. Good faith pricing is permitted if, in the Adviser’s opinion, the validity of market quotations appears to be questionable based on factors such as evidence of a thin market in the security based on a small number of quotations, a significant event occurs after the close of a market but before the Fund’s NAV calculation that may affect a security’s value, or the Adviser is aware of any other data that calls into question the reliability of market quotations.

Good faith pricing may also be used in instances when the bonds in which the Fund invests default or otherwise cease to have market quotations readily available.

Futures

The Fund may invest in futures contracts in accordance with its investment objectives. The Fund does so for a variety of reasons including for cash management, hedging or non-hedging purposes in an attempt to achieve the Fund’s investment objective. A futures contract provides for the future sale by one party and purchase by another party of a specified quantity of the security or other financial instrument at a specified price and time. A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract was originally written. Futures transactions may result in losses in excess of the amount invested in the futures contract. There can be no guarantee that there will be a correlation between price movements in the hedging vehicle and in the portfolio securities being hedged. An incorrect correlation could result in a loss on both the hedged securities in a fund and the hedging vehicle so that the portfolio return might have been greater had hedging not been attempted. There can be no assurance that a liquid market will exist at a time when a fund seeks to close out a futures contract or a futures option position. Lack of a liquid market for any reason may prevent a fund from liquidating an unfavorable position, and the fund would remain obligated to meet margin requirements until the position is closed. In addition, a fund could be exposed to risk if the counterparties to the contracts are unable to meet the terms of their contracts. With exchange-traded futures, there is minimal counterparty credit risk to the Fund since futures are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. The Fund is party to certain enforceable master netting arrangements, which provide for the right of offset under certain circumstances, such as the event of default.

December 31, 2024 (Unaudited)

When a purchase or sale of a futures contract is made by a fund, the fund is required to deposit with its custodian (or broker, if legally permitted) a specified amount of liquid assets (“initial margin”). The margin required for a futures contract is set by the exchange on which the contract is traded and may be modified during the term of the contract. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract that is returned to the Fund upon termination of the contract, assuming all contractual obligations have been satisfied. These amounts are included in Deposit with broker for futures contracts on the Statement of Assets and Liabilities. Each day the Fund may pay or receive cash, called “variation margin,” equal to the daily change in value of the futures contract. Such payments or receipts are recorded for financial statement purposes as unrealized gains or losses by the Fund. Variation margin does not represent a borrowing or loan by the Fund but instead is a settlement between the Fund and the broker of the amount one would owe the other if the futures contract expired. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

Derivative Instruments: The following tables disclose the amounts related to the Fund’s use of derivative instruments.

5. NEW ACCOUNTING PRONOUNCEMENTS AND RULE ISSUANCES

In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (“ASU 2023-07”). Adoption of the new standard impacted disclosures only and did not affect the Fund’s financial position nor the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by a public entity’s chief operating decision maker (the “CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Fund’s Principal Financial Officer, acting together as the Fund’s CODM, has determined that the Fund has operated as a single segment since inception. The CODM monitors the operating results of the Fund, as a whole, and the Fund’s long-term strategic asset allocation is pre-determined in accordance with the terms of the related Prospectus, based on the defined investment objectives and strategies that are executed by the Fund’s portfolio management team. The financial information, in the form of the Fund’s holdings, total returns, expense ratios, and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions) are used by the CODM to assess the Fund’s performance versus the Fund’s benchmark and to make resource allocation decisions for the Fund’s segment, which is consistent with that presented within the Fund’s financial statements. Segment assets are reflected on the Fund’s Statement of Assets and Liabilities as “Total Assets” and significant segment expenses are listed on the Statement of Operations.

The Fund did not utilize the BNP Credit Agreement for the six months ended December 31, 2024. There was no outstanding balance on the BNP Credit Agreement as of December 31, 2024.

7. TAX BASIS INFORMATION

It is the Fund’s policy to meet the requirements of the IRC applicable to regulated investment companies, and to distribute all of its taxable net income to its shareholders. In addition, the Fund intends to pay distributions as required to avoid imposition of excise tax. Therefore, no federal income tax provision is required.

Tax Basis of Distributions to Shareholders: The character of distributions made during the year from net investment income or net realized gains may differ from its ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the fiscal year in which the income or realized gains were recorded by the Fund.

The amounts and characteristics of tax basis distributions and composition of distributable earnings/(accumulated losses) are finalized at fiscal year-end and are not available for the six months ended December 31, 2024.

The tax character of the distributions paid by the Fund during the fiscal year ended June 30, 2024, was as follows:

	For the Year Ended
	June 30, 2024
Ordinary Income	$	20,314,841
Ordinary Income Preferred		4,790,698
Return of Capital		7,581,377
Total	$	32,686,916

Notes to Financial Statements

December 31, 2024 (Unaudited)

Unrealized Appreciation and Depreciation on Investments: As of December 31, 2024, net unrealized appreciation/(depreciation) of investments based on federal tax costs was as follows:

Cost of investments for income tax purposes	$	401,726,788
Gross appreciation on investments (excess of value over tax cost)		7,080,884
Gross depreciation on investments (excess of tax cost over value)		(50,468,033	)
Net unrealized depreciation on investments	$	(43,387,149	)

The difference between book and tax basis unrealized appreciation/(depreciation) for the Fund is primarily attributable to wash sales, income adjustments on income-only securities and grantor trusts.

The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Management has analyzed the Fund’s tax positions, and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on U.S. tax returns and state tax returns filed since inception of the Fund. No income tax returns are currently under examination. The tax years since 2018 remain subject to examination by the tax authorities in the United States. The Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

8. INVESTMENT TRANSACTIONS

Investment transactions for the six months ended December 31, 2024, excluding long term U.S. Government Obligations and short-term investments, were as follows:

Dividend Reinvestment Plan

December 31, 2024 (Unaudited)

The Fund has an automatic dividend reinvestment plan commonly referred to as an “opt-out” plan. Unless the registered owner of common shares elects to receive cash by contacting DST (the “Plan Administrator”), all dividends and distributions declared on common shares will be automatically reinvested by the Plan Administrator for shareholders in the Fund’s Automatic Dividend Reinvestment Plan (the “Plan”), in additional common shares. Common shareholders who elect not to participate in the Plan will receive all dividends and other distributions in cash paid by check mailed directly to the shareholder of record (or, if the common shares are held in street or other nominee name, then to such nominee) by the Plan Administrator as dividend disbursing agent. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Plan Administrator prior to the dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Such notice will be effective with respect to a particular dividend or other distribution (together, a “Dividend”). Some brokers may automatically elect to receive cash on behalf of common shareholders and may re-invest that cash in additional common shares. Reinvested Dividends will increase the Fund’s Managed Assets on which the management fee is payable to the Adviser (and by the Adviser to the Sub-Adviser).

Whenever the Fund declares a Dividend payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in common shares. The common shares will be acquired by the Plan Administrator for the participants’ accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund (“Newly Issued Common Shares”) or (ii) by purchase of outstanding common shares on the open market (“Open-Market Purchases”) on the NYSE or elsewhere. If, on the payment date for any Dividend, the closing market price plus estimated brokerage commissions per common share is equal to or greater than the NAV per common share, the Plan Administrator will invest the Dividend amount in Newly Issued common shares on behalf of the participants. The number of Newly Issued common shares to be credited to each participant’s account will be determined by dividing the dollar amount of the Dividend by the Fund’s NAV per common share on the payment date. If, on the payment date for any Dividend, the NAV per common share is greater than the closing market value plus estimated brokerage commissions (i.e., the Fund’s common shares are trading at a discount), the Plan Administrator will invest the Dividend amount in common shares acquired on behalf of the participants in Open-Market Purchases.

In the event of a market discount on the payment date for any Dividend, the Plan Administrator will have until the last business day before the next date on which the common shares trade on an “ex-dividend” basis or 30 days after the payment date for such Dividend, whichever is sooner (the “Last Purchase Date”), to invest the Dividend amount in common shares acquired in Open-Market Purchases. It is contemplated that the Fund will pay monthly income Dividends. If, before the Plan Administrator has completed its Open-Market Purchases, the market price per common share exceeds the NAV per common share, the average per common share purchase price paid by the Plan Administrator may exceed the NAV of the common shares, resulting in the acquisition of fewer common shares than if the Dividend had been paid in Newly Issued common shares on the Dividend payment date. Because of the foregoing difficulty with respect to Open-Market Purchases, the Plan provides that if the Plan Administrator is unable to invest the full Dividend amount in Open-Market Purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Administrator may cease making Open-Market Purchases and may invest the uninvested portion of the Dividend amount in Newly Issued common shares at the NAV per common share at the close of business on the Last Purchase Date.

Dividend Reinvestment Plan

December 31, 2024 (Unaudited)

The Plan Administrator maintains all shareholders’ accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common shares in the account of each Plan participant will be held by the Plan Administrator on behalf of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for shares held under the Plan in accordance with the instructions of the participants.

Beneficial owners of common shares who hold their common shares in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan. In the case of common shareholders such as banks, brokers or nominees which hold shares for others who are the beneficial owners, the Plan Administrator will administer the Plan on the basis of the number of common shares certified from time to time by the record shareholder’s name and held for the account of beneficial owners who participate in the Plan.

There will be no brokerage charges with respect to common shares issued directly by the Fund. However, each participant will pay a pro rata share of brokerage commissions incurred in connection with Open-Market Purchases. The automatic reinvestment of Dividends will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such Dividends, even though such participants have not received any cash with which to pay the resulting tax. Participants that request a sale of common shares through the Plan Administrator are subject to brokerage commissions.

The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. All correspondence or questions concerning the Plan should be directed to the Plan Administrator at (844) 569-4750.

Consideration and Approval of
Advisory and Sub-Advisory Agreements

December 31, 2024 (Unaudited)

Consideration of the Advisory Agreement

At a meeting (the “Meeting”) of the Board of Directors (the “Board” or the “Directors”) of the RiverNorth/DoubleLine Strategic Opportunity Fund, Inc. (the “Fund”) held on November 12-13, 2024 and called expressly for that purpose, the Board, including a majority of the Directors who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended) (the “Independent Directors”), considered the renewal of the advisory agreement between RiverNorth Capital Management, LLC (the “Adviser”) and the Fund (the “Advisory Agreement”). In its consideration of the Advisory Agreement, the Board considered information and materials furnished by the Adviser in advance of and at the Meeting and was afforded the opportunity to request additional information and to ask questions of the Adviser to obtain information that it believed to be reasonably necessary to evaluate the terms of the Advisory Agreement. The Board received materials compiled by the Adviser and the Fund’s administrator, including a copy of the Advisory Agreement, the Adviser’s response to a questionnaire regarding the Adviser’s profitability, organization, management and operations, a copy of the Adviser’s Form ADV, the Adviser’s audited financial statements, information regarding the Adviser’s assets under management, an overview of the Fund’s cumulative and annualized returns as compared to the Fund’s benchmark, the Fund’s fact sheet for the quarter ended September 30, 2024, a performance comparison of the Fund to other funds managed by the Adviser, information regarding the Adviser’s compliance programs and a third-party comparison report regarding the Fund’s performance and fees compared to benchmark indices and peer funds provided by FUSE Research Network, LLC (“FUSE”). The Board considered the following factors, among others, in reaching its determination to renew the Advisory Agreement: (i) the investment performance of the Fund and the investment performance of the Adviser, (ii) the nature, extent and quality of the services provided by the Adviser to the Fund, (iii) the experience and qualifications of the personnel providing such services, (iv) the costs of the services provided and the profits to be realized by the Adviser and any of its affiliates from the relationship with the Fund, (v) the extent to which economies of scale will be realized by the Fund as it grows, and (vi) whether the Fund’s fee levels reflected the economies of scale to the benefit of the Fund’s shareholders.

The Directors relied upon the advice of independent legal counsel and their own business judgment in determining the material factors to be considered in evaluating the Advisory Agreement and the weight to be given to each such factor. The Directors’ conclusions were based on an evaluation of all of the information provided and were not the result of any one factor. Moreover, each Director may have afforded different weight to the various factors in reaching conclusions with respect to the Advisory Agreement. Although not meant to be all-inclusive, the following discussion summarizes the factors considered and conclusions reached by the Directors in determining to renew the Advisory Agreement at the Meeting and at the November 4, 2024 special meeting of the Board that was held to review and discuss the materials and information the Board requested from the Adviser related to the Advisory Agreement, including during executive sessions with their independent legal counsel.

Performance, Fees and Expenses

The Board reviewed the performance of the Fund for the three-month, one-year, three-year, five-year and since inception periods ended September 30, 2024. These returns were compared to the returns of Tactical-Flexible Allocation funds identified by FUSE (the “Performance Group”). The Board considered the Fund’s net asset value (“NAV”) and market price returns relative to the returns for funds in the Performance Group, noting that on a NAV basis, the Fund had outperformed the median of the Performance Group for the three-month period ended September 30, 2024 and underperformed the median of its Performance Group for the one-year, three-year, five-year and since inception periods ended September 30, 2024. Using market price returns, the Board observed that the Fund had outperformed the median of its Performance Group for the three-month period ended September 30, 2024 and underperformed the median of its Performance Group for the one-year, three-year, five-year and since inception periods ended September 30, 2024. The Directors also noted that on a NAV basis, the Fund had outperformed its benchmark for the three-month, one-year, three-year, five-year and since inception periods ended September 30, 2024. The Directors also reviewed the Fund’s performance relative to other funds managed by the Adviser. It was noted that the Adviser had indicated that the Performance Group is not entirely reflective of the Fund due to its unique investment strategy.

Consideration and Approval of
Advisory and Sub-Advisory Agreements

December 31, 2024 (Unaudited)

As to the comparative fees and expenses, the Directors considered the management and other fees paid by the Fund and compared those to the management and other fees paid by funds in FUSE’s Tactical-Flexible Allocation fund peer group (the “Expense Group”). The Directors also noted the fact that the fee payable to DoubleLine Capital, LP (the “Sub-Adviser”) is paid by the Adviser and not the Fund. The Board noted that the Fund’s annual net expense ratio was higher than the Expense Group median. The Directors also reviewed total net and gross expense rankings against its peers calculated on the basis of each fund’s average managed assets to mitigate the distortions caused by differing levels of leverage.

The Board noted that the annual management fee for the Fund was above the median paid by the Expense Group but within the range of the fees paid by the funds in the Expense Group. The Directors also reviewed the Fund’s fees relative to other funds managed by the Adviser. The Board, including the Independent Directors, determined that the fees were reasonable given the nature of the Fund’s unique investment strategy, the capabilities of the Adviser and the Sub-Adviser and the nature of the services provided to the Fund.

Nature, Extent and Quality of Services

As to the nature, extent and quality of the services provided by the Adviser to the Fund, the Board considered that under the terms of the Advisory Agreement, the Adviser, subject to the supervision of the Board, provides or arranges to be provided to the Fund such investment advice as the Adviser, in its discretion, deems advisable and furnishes or arranges to be furnished a continuous investment program for the Fund consistent with the Fund’s investment objective and policies. The Board reviewed the Adviser’s Form ADV, which was previously provided to the Board and that provided details regarding the experience of each of the Adviser’s personnel. The Adviser also provided additional information regarding its experience managing other investment accounts. Based on the foregoing information, the Board, including the Independent Directors, concluded that the Adviser had provided quality services and would continue to do so for the Fund.

Profitability and Other Benefits

As to the cost of the services provided and the profits to be realized by the Adviser, the Board reviewed the Adviser’s estimates of its profitability and its financial condition. The Board reviewed the Adviser’s financial statements and noted the Adviser’s financial condition is stable as income from its asset management operations have contributed to higher revenues for the Adviser. The Board acknowledged the Adviser’s management fees were comparable to those charged to other funds to which the Adviser provides advisory or sub-advisory services. It was noted that, when launching a closed-end fund, such as the Fund, the Adviser covers the underwriting costs, which is a significant investment. The Board, including the Independent Directors, determined that the Advisory Agreement, with respect to the Fund was not overly profitable to the Adviser and the financial condition of the Adviser was adequate.

Consideration and Approval of
Advisory and Sub-Advisory Agreements

December 31, 2024 (Unaudited)

The Board noted that the Adviser has no affiliations with the Fund’s transfer agent, fund accountant, custodian, or distribution-related service providers utilized by the Fund and therefore does not derive any benefits from the relationships these parties may have with the Fund.

Conclusion

Having requested and received such information from the Adviser as the Board believed to be reasonably necessary to evaluate the terms of the Advisory Agreement, and as assisted by the advice of independent counsel, the Board, including the Independent Directors, concluded that renewal of the Advisory Agreement was in the best interests of the Fund and its shareholders.

Consideration of the Sub-Advisory Agreement

At the Meeting, the Board, including the Independent Directors, also considered the renewal of the sub-advisory agreement (the “Sub-Advisory Agreement”) between the Adviser and Sub-Adviser. In its consideration of the Sub-Advisory Agreement, the Board considered information and materials furnished by the Adviser and the Sub-Adviser in advance of and at the Meeting and was afforded the opportunity to request additional information and to ask questions of the Adviser and Sub-Adviser to obtain information that it believed to be reasonably necessary to evaluate the terms of the Sub-Advisory Agreement. The Board received materials compiled by the Sub-Adviser and the Adviser, including a copy of the Sub-Advisory Agreement, the Sub-Adviser’s response to a questionnaire regarding its profitability, management and operations, a copy of the Sub-Adviser’s Form ADV, information regarding the Sub-Adviser’s compliance programs and information regarding the performance of the Fund’s benchmark indices and peer funds. The Board considered the following factors, among others, in reaching its determination to renew the Sub-Advisory Agreement: (i) the investment performance of the Fund and the investment performance of the Sub-Adviser, (ii) the nature, extent and quality of the services provided by the Sub-Adviser to the Fund, (iii) the experience and qualifications of the personnel providing such services, (iv) the costs of the services provided and the profits to be realized by the Sub-Adviser and any of its affiliates from the relationship with the Fund, (v) the extent to which economies of scale will be realized by the Fund as it grows, and (vi) whether the fee level of the Fund reflected the economies of scale to the benefit of the Fund’s shareholders.

The Directors relied upon the advice of independent legal counsel and their own business judgment in determining the material factors to be considered in evaluating the Sub-Advisory Agreement and the weight to be given to each such factor. The Directors’ conclusions were based on an evaluation of all of the information provided and were not the result of any one factor. Moreover, each Director may have afforded different weight to the various factors in reaching conclusions with respect to the Sub-Advisory Agreement. Although not meant to be all-inclusive, the following discussion summarizes the factors considered and conclusions reached by the Directors in determining to renew the Sub-Advisory Agreement at the Meeting and at the November 4, 2024 special meeting of the Board that had been called to review and discuss the materials and information the Board had requested from the Sub-Adviser related to the Sub-Advisory Agreement.

Performance, Fees and Expenses

The Board reviewed the performance of the portion of the Fund managed by the Sub-Adviser. The Board recalled its deliberations regarding the Fund’s performance while considering the renewal of the Advisory Agreement.

As to the comparative fees and expenses, the Board considered the management fee paid by the Fund to the Adviser and noted that the Adviser pays the Sub-Adviser from its fee, which the Board had previously determined was reasonable. The Board also compared the sub-advisory fee paid by the Adviser to the Sub-Adviser against the fees the Sub-Adviser charges other clients to manage similar strategies.

Nature, Extent and Quality of Services

As to the nature, extent and quality of the services provided by the Sub-Adviser, the Board considered that under the terms of the Sub-Advisory Agreement, the Sub-Adviser, subject to the supervision of the Board, provides to the Fund such investment advice as the Sub-Adviser, in its discretion, deems advisable and furnishes or arranges to be furnished a continuous investment program for the Fund consistent with the Fund’s investment objective and policies. The Board reviewed the Form ADV of the Sub-Adviser, which provided details regarding the experience of the Sub-Adviser’s investment personnel. The Sub-Adviser also provided additional information regarding its operations and experience managing other investment accounts. Based on the foregoing information, the Board, including the Independent Directors, concluded that the Sub-Adviser had provided quality services and would continue to do so for the Fund.

Profitability and Other Benefits

As to the cost of the services provided and the profits to be realized by the Sub-Adviser, the Board reviewed the Sub-Adviser’s financial condition. The Board noted that the financial condition of the Sub-Adviser was stable. The Board, including the Independent Directors determined that the Sub-Advisory Agreement and the compensation to the Sub-Adviser was reasonable and the financial condition of the Sub-Adviser was adequate. The Board noted that the Sub-Adviser had no affiliations with the Fund’s transfer agent, fund accountant, custodian, or distribution-related service providers and therefore does not derive any benefits from the relationships these parties may have with the Fund.

Conclusion

Having requested and received such information from the Adviser and Sub-Adviser as the Board believed to be reasonably necessary to evaluate the terms of the Sub-Advisory Agreement, and as assisted by the advice of independent counsel, the Board, including the Independent Directors, concluded that renewal of the Sub-Advisory Agreement was in the best interests of the Fund and its shareholders.
