For the fiscal year ended December 31, 2025, the Fund returned 7.27%, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 6.46%, reflecting performance at the net asset value (NAV) of Class C shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.42%, reflecting performance at the net asset value (NAV) of Class F shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.60%, reflecting performance at the net asset value (NAV) of Class F3 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

For additional information about the Fund, including its Prospectus, Statement of Additional Information, financial statements, holdings and proxy information, please visit lordabbett.com/FundDocuments.
The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.54%, reflecting performance at the net asset value (NAV) of Class I shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

For additional information about the Fund, including its Prospectus, Statement of Additional Information, financial statements, holdings and proxy information, please visit lordabbett.com/FundDocuments.
The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.05%, reflecting performance at the net asset value (NAV) of Class P shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 6.91%, reflecting performance at the net asset value (NAV) of Class R2 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.03%, reflecting performance at the net asset value (NAV) of Class R3 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.28%, reflecting performance at the net asset value (NAV) of Class R4 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.51%, reflecting performance at the net asset value (NAV) of Class R5 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

For additional information about the Fund, including its Prospectus, Statement of Additional Information, financial statements, holdings and proxy information, please visit lordabbett.com/FundDocuments.
The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

For the fiscal year ended December 31, 2025, the Fund returned 7.61%, reflecting performance at the net asset value (NAV) of Class R6 shares, with all distributions reinvested, compared to the 11.05% return of a securities market index with investment characteristics similar to those of the Fund, the Russell Midcap Value Index. The Fund's broad-based securities market index, the S&P 500 Index, returned 17.88% over the same period.
Positive factors for the markets included the Federal Reserve's (Fed) shift towards dovish monetary policy, with rate cuts delivered in September, October, and December, better-than-expected corporate earnings results and forward earnings guidance, continued generative artificial intelligence growth tailwinds, and economic data resilience, with consumer spending remaining firm. During the period, the market had mixed expectations for additional Fed rate cuts due to uncertainty around the effects of tariffs, persistent inflation, headwinds from trade talks, and mixed employment data.
Top contributors to performance: Security selection within the Real Estate sector contributed to relative performance, led by an overweight allocation to CBRE Group, Inc. Security selection within the Materials sector also contributed to relative performance, led by an overweight allocation to Steel Dynamics, Inc.
Top detractors from performance: Security selection within the Financials sector detracted from relative performance, led by an overweight allocation to Kemper Corporation. Security selection within the Industrials sector also detracted from relative performance, led by an overweight allocation to Saia, Inc.

As of February 10, 2025, the Fund may invest up to 20% of its net assets in securities of foreign companies, including emerging market companies, American Depositary Receipts, Global Depositary Receipts, and other similar depositary receipts.
For additional information about the Fund, including its Prospectus, Statement of Additional Information, financial statements, holdings and proxy information, please visit lordabbett.com/FundDocuments.
The Fund has adopted a policy that allows it to send only one copy of the Fund's prospectus, proxy material, annual report and semiannual report (or related notice of internet availability of annual report and semiannual report) to certain shareholders residing at the same "household." This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be "householded," please call Lord Abbett at 888-522-2388.

Lord Abbett Mid Cap Stock Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end management investment company and was incorporated under Maryland law on March 14, 1983.
The Fund's investment objective is to seek capital appreciation through investments, primarily in equity securities, which are believed to be undervalued in the marketplace. The Fund has eleven active classes of shares: Class A, C, F, F3, I, P, R2, R3, R4, R5 and R6, each with different expenses and dividends. A front-end sales charge is normally added to the net asset value ("NAV") for Class A shares. There is no front-end sales charge in the case of Class C, F, F3, I, P, R2, R3, R4, R5 and R6 shares, although there may be a contingent deferred sales charge ("CDSC") in certain cases as follows: Class A shares purchased without a sales charge and redeemed before the first day of the month in which the one-year anniversary of the purchase falls (subject to certain exceptions as set forth in the Fund's prospectus); and Class C shares redeemed before the first anniversary of purchase. Class C shares automatically convert to Class A shares on the 25th day of the month (or, if the 25th day is not a business day, the next business day thereafter) following the eighth anniversary of the month on which the purchase order was accepted, provided that the Fund or financial intermediary through which a shareholder purchased Class C shares has records verifying that the Class C shares have been held at least eight years. The Fund's Class P shares are closed to substantially all new investors, with certain exceptions as set forth in the Fund's prospectus.
Basis of Preparation
The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946 Financial Services - Investment Companies. The preparation of the financial statements in conformity with generally accepted accounting principles in the United States of America ("U.S. GAAP") requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.
Segment Reporting
An operating segment is defined in FASB Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures ("ASU 2023-07") 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 the public entity's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available.
The CODM for the Fund is Lord, Abbett & Co. LLC ("Lord Abbett") through its Management, Investment and Operating Committees, which are responsible for assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment based on the fact that the CODM monitors the operating results of the Fund as a whole and that the Fund's long-term strategic asset allocation is pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund's portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with that presented within the Fund's Schedule of Investments, Statement of Assets and Liabilities, Statement of Operations, Statements of Changes in Net Assets and Financial Highlights.

Notes to Financial Statements (continued)
| 2. | SIGNIFICANT ACCOUNTING POLICIES |
| (a) | Investment Valuation-Under procedures approved by the Fund's Board of Directors (the "Board"), the Board has designated the determination of fair value of the Fund's portfolio investments to Lord Abbett as its valuation designee. Accordingly, Lord Abbett is responsible for, among other things, assessing and managing valuation risks, establishing, applying and testing fair value methodologies, and evaluating pricing services. Lord Abbett has formed a pricing committee (the "Pricing Committee") that performs these responsibilities on behalf of Lord Abbett, administers the pricing and valuation of portfolio investments and ensures that prices utilized reasonably reflect fair value. Among other things, these procedures allow Lord Abbett, subject to Board oversight, to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value. |
| Securities actively traded on any recognized U.S. or non-U.S. exchange or on the NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Pricing Committee uses a third-party fair valuation service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that correlate to the fair-valued securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and ask prices. | |
| Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values, and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof periodically reviews reports that may include fair value determinations made by the Pricing Committee, related market activity, inputs and assumptions, and retrospective comparison of prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee. | |
| Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value. Investments in open-end money market mutual funds are valued at their NAV as of the close of each business day. | |
| Fair Value Measurements-Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used 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 (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. |
13
Notes to Financial Statements (continued)
| Unobservable inputs reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is 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.); and | |
| • | Level 3 - | significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). |
| A summary of inputs used in valuing the Fund's investments as of December 31, 2025 and, if applicable, Level 3 rollforwards for the fiscal year then ended is included in the Fund's Schedule of Investments. | |
| Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. | |
| (b) | Expenses-Expenses, excluding class-specific expenses, are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. In addition, Class F3 and R6 shares bear only their class-specific shareholder servicing expenses. Class A, C, F, P, R2, R3, and R4 shares bear their class-specific share of all expenses and fees relating to the Fund's 12b-1 Distribution Plan. |
| (c) | Foreign Transactions-The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund's records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain/(loss), if applicable, is included in Net change in unrealized appreciation/(depreciation) on translation of assets and liabilities denominated in foreign currencies in the Fund's Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions, if applicable, are included in Net realized gain/(loss) on foreign currency related transactions in the Fund's Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities. |
| The Fund uses foreign currency exchange contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms. | |
| (d) | Income Taxes-It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required. |
| Management has reviewed the Fund's tax positions for all open tax years and has determined that as of December 31, 2025, no liability for Federal Income tax is required in the Fund's financial statements for net unrecognized tax benefits. However, management's conclusions may be subject to future review based on changes in, or the interpretation of, the accounting |
14
Notes to Financial Statements (continued)
| standards or tax laws and regulations. The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The Fund's Federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service. The statutes of limitations on the Fund's state and local tax returns may remain open for an additional year depending upon the Fund's jurisdiction. | |
| (e) | Investment Income-Dividend income, if any, is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other, if applicable, in the Statement of Operations. Withholding taxes on foreign dividends, if applicable, have been provided for in accordance with the applicable country's tax rules and rates. Investment income is allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. |
| (f) | Repurchase Agreements-The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities. |
| Due to the absence of a master netting agreement related to the Fund's participation in repurchase agreements, no offsetting disclosures have been made on behalf of the Fund. | |
| (g) | Security Transactions-Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method. Realized and unrealized gains/(losses) are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. |
| 3. | MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES |
Management Fee
The Fund has a management agreement with Lord Abbett, pursuant to which Lord Abbett provides the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund's investment portfolio. The management fee is accrued daily and payable monthly.
The management fee is based on the Fund's average daily net assets at the following annual rates:
| First $200 million | .75% |
| Next $300 million | .65% |
| Over $500 million | .50% |
For the fiscal year ended December 31, 2025, the effective management fee, net of any applicable waiver, was at an annualized rate of .59% of the Fund's average daily net assets.
15
Notes to Financial Statements (continued)
In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund's average daily net assets. The fund administration fee is accrued daily and payable monthly.
Lord Abbett voluntarily waived $23,099 of certain fees and expenses during the fiscal year ended December 31, 2025.
12b-1 Distribution Plan
The Fund has adopted a distribution plan with respect to Class A, C, F, P, R2, R3 and R4 shares pursuant to Rule 12b-1 under the 1940 Act, which provides for the payment of ongoing distribution and service fees to Lord Abbett Distributor LLC (the "Distributor"), an affiliate of Lord Abbett. The distribution and service fees are accrued daily and payable monthly. The following annual rates have been authorized by the Board pursuant to the plan:
| Fees* | Class A | Class C | Class F(1) | Class P | Class R2 | Class R3 | Class R4 | ||||||||
| Service | .25% | (2) | .25% | - | .25% | .25% | .25% | .25% | |||||||
| Distribution | - | .75% | .10% | .20% | .35% | .25% | - |
| * | The Fund may designate a portion of the aggregate fees attributable to service activities for purposes of calculating Financial Industry Regulatory Authority, Inc. sales charge limitations. |
| (1) | The Class F shares Rule 12b-1 fee may be designated as a service fee in limited circumstances as described in the Fund's prospectus. |
| (2) | Annual Service fee on shares sold prior to June 1, 1990 was .15% of the average daily net assets attributable to Class A shares. |
Class F3, Class I, Class R5 and Class R6 shares do not have a distribution plan.
Commissions
The Distributor received the following commissions on sales of shares of the Fund, after concessions were paid to authorized dealers, during the fiscal year ended December 31, 2025:
|
Distributor Commissions |
Dealers' Concessions |
|
| $ 18,483 | $ 115,803 |
The Distributor received CDSCs of $752 for Class C shares for the fiscal year ended December 31, 2025.
One Director and certain of the Fund's officers have an interest in Lord Abbett.
| 4. | DISTRIBUTIONS AND TAX INFORMATION |
Dividends are paid from net investment income, if any. Capital gain distributions are paid from taxable net realized gains from investments transactions, reduced by allowable capital loss carryforwards, if any. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions, which exceed earnings and profits for tax purposes, are reported as a tax return of capital.

Notes to Financial Statements (continued)
The Fund is permitted to purchase and sell securities ("cross-trade") from and to other Lord Abbett funds or client accounts pursuant to procedures approved by the Board in compliance with Rule 17a-7 under the 1940 Act (the "Rule"). Each cross-trade is executed at a fair market price in compliance with provisions of the Rule. For the fiscal year ended December 31, 2025, the Fund did not engage in cross-trade purchases or sales.
| 6. | DIRECTORS' REMUNERATION |
The Fund's officers and one Director, who are associated with Lord Abbett, do not receive any compensation from the Fund for serving in such capacities. Independent Directors' fees are allocated among all Lord Abbett-sponsored funds primarily based on the relative net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors may elect to defer receipt of a portion of Directors' fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the Fund. Such amounts and earnings accrued thereon are included in Directors' fees in the Statement of Operations and in Directors' fees payable in the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.
| 7. | LINE OF CREDIT |
For the period ended June 5, 2025, the Fund and certain other funds managed by Lord Abbett (collectively, the "Participating Funds") were party to a syndicated line of credit facility with various lenders for $1.6 billion (the "Syndicated Facility") under which State Street Bank and Trust Company ("SSB") participated as a lender and as agent for the lenders. The Participating Funds were subject to graduated borrowing limits of the lesser of either one-third or one-fifth of unencumbered fund net assets and $250 million, $700 million or $1 billion, in each case based on past borrowings and likelihood of future borrowings, among other factors.
Effective June 6, 2025, the Participating Funds renewed the Syndicated Facility for $1.675 billion. The Participating Funds are subject to graduated borrowing limits of the lesser of either one-third or one-fifth of unencumbered fund net assets and $250 million, $300 million, $700 million or $1 billion, in each case based on past borrowings and likelihood of future borrowings, among other factors.
For the period ended June 5, 2025, the Participating Funds were also party to an additional uncommitted line of credit facility with SSB for $330 million (the "Bilateral Facility"). Under the Bilateral Facility, the Participating Funds were subject to graduated borrowing limits of the lesser of either one-third or one-fifth of unencumbered fund net assets and $250 million based on past borrowings and likelihood of future borrowings, among other factors.
Effective June 6, 2025, the Participating Funds renewed the Bilateral Facility in the same amount. The Participating Funds remain subject to the same borrowing limits as were in place prior to the renewal.
These credit facilities are to be used for short-term working capital purposes as additional sources of liquidity to satisfy redemptions.
For the fiscal year ended December 31, 2025, the Fund did not utilize the Syndicated Facility or Bilateral Facility.
18
Notes to Financial Statements (continued)
| 8. | INTERFUND LENDING PROGRAM |
Pursuant to an exemptive order issued by the U.S. Securities and Exchange Commission ("SEC exemptive order") certain registered open-end management investment companies managed by Lord Abbett, including the Fund, participate in a joint lending and borrowing program (the "Interfund Lending Program"). The SEC exemptive order allows the funds that participate in the Interfund Lending Program to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.
During the fiscal year ended December 31, 2025, the Fund did not participate as a borrower or lender in the Interfund Lending Program.
| 9. | CUSTODIAN AND ACCOUNTING AGENT |
SSB is the Fund's custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund's NAV.
| 10. | SECURITIES LENDING AGREEMENT |
The Fund has established a securities lending agreement with Citibank, N.A. for the lending of securities to qualified brokers in exchange for securities or cash collateral equal to at least the market value of securities loaned, plus interest, if applicable. Cash collateral is invested in an approved money market fund. In accordance with the Fund's securities lending agreement, the market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Fund on the next business day. As with other extensions of credit, the Fund may experience a delay in the recovery of its securities or incur a loss should the borrower of the securities breach its agreement with the Fund or the borrower becomes insolvent at a time when the collateral is insufficient to cover the cost of repurchasing securities on loan. Any income earned from securities lending is included in Securities lending net income, if any, in the Fund's Statement of Operations.
The initial collateral received by the Fund is required to have a value equal to at least 100% of the market value of the securities loaned. The collateral must be marked-to-market daily to cover increases in the market value of the securities loaned (or potentially a decline in the value of the collateral). In general, the risk of borrower default will be borne by Citibank, N.A.; the Fund will bear the risk of loss with respect to the investment of the cash collateral. The advantage of such loans is that the Fund continues to receive income on loaned securities while receiving a portion of any securities lending fees and earning returns on the cash amounts which may be reinvested for the purchase of investments in securities.
As of December 31, 2025, the Fund did not have any securities on loan.
| 11. | INVESTMENT RISKS |
The Fund is subject to the general risks and considerations associated with equity investing, as well as the particular risks associated with value and mid-sized company stocks. The value of an investment will fluctuate in response to movements in the equity securities market in general, and to the changing prospects of individual companies in which the Fund invests. The market may fail to recognize for a long time the intrinsic value of particular value stocks the Fund may hold. Value investing is also subject to the risk that a company judged to be undervalued may actually be appropriately priced or even overpriced. The mid-sized company stocks in which the Fund invests may be less able to weather economic shifts or other adverse developments than those of larger, more established companies.
19
Notes to Financial Statements (continued)
Accordingly, mid-sized company securities tend to be more sensitive to changing economic, market, and industry conditions and tend to be more volatile and less liquid than equity securities of larger companies, especially over the short term. In addition, if the Fund's assessment of a company's value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.
Because the Fund invests in real estate investment trusts ("REITS"), it may be subject to the risks that impact the value of the underlying properties or mortgages of the REITs in which it invests. These risks include loss to casualty or condemnation, and changes in supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Other factors that may adversely affect REITs include poor performance by management of the REIT, changes to the tax laws, or failure by the REIT to qualify for tax-free distribution of income, and changes in local, regional, or general economic conditions.
Due to the Fund's investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information, and other risks. As compared with companies organized and operated in the U.S., these companies may be more vulnerable to economic, political and social instability and subject to less government supervision, lack of transparency, inadequate regulatory and accounting standards, and foreign taxes. The securities of foreign companies also may be subject to inadequate exchange control regulations, the imposition of economic sanctions or other government restrictions, higher transaction and other costs, and delays in settlement to the extent they are traded on non-U.S. exchanges or markets.
Geopolitical and other events, such as war, acts of terrorism, tariffs and other restrictions on trade, natural disasters, the spread of infectious illnesses, epidemics and pandemics, environmental and other public health issues, supply chain disruptions, inflation, recessions or other events, and governments' reactions to such events, may lead to increased market volatility and instability in world economies and markets generally and may have adverse effects on the performance of the Fund and its investments.
A widespread health crisis, such as a global pandemic, could cause substantial market volatility, impact the ability to complete redemptions, and adversely impact Fund performance. For example, the effects to public health, business and market conditions resulting from the COVID-19 pandemic have had, and may in the future have, a significant negative impact on the performance of the Fund's investments, including exacerbating other pre-existing political, social and economic risks. In addition, the increasing interconnectedness of markets around the world may result in many markets being affected by events or conditions in a single country or region or events affecting a single or small number of issuers.
It is difficult to accurately predict or foresee when events or conditions affecting the U.S. or global financial markets, economies, and issuers may occur, the effects of such events or conditions, potential escalations or expansions of these events, possible retaliations in response to sanctions or similar actions and the duration or ultimate impact of those events. The foregoing could disrupt the operations of the Fund and its service providers, adversely affect the value and liquidity of the Fund's investments and negatively impact the Fund's performance and your investment in the Fund.

Report of Independent Registered Public Accounting Firm
To the shareholders and the Board of Directors of Lord Abbett Mid Cap Stock Fund, Inc.
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statement of assets and liabilities of Lord Abbett Mid Cap Stock Fund, Inc. (the "Fund"), including the schedule of investments, as of December 31, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2025, by correspondence with the custodian and counterparties; when replies were not received from counterparties, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.
