How did the Fund perform last year and what affected its performance?

For the fiscal year ended July 31, 2026, the Fund returned 40.20%, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared to the 36.44% return of a securities market index with investment characteristics similar to those of the Fund, the MSCI Emerging Markets Index (Net). The Fund's broad-based securities market index, the MSCI EAFE Net Index, returned 24.33% over the same period.

Markets navigated a resilient economic backdrop amid geopolitical and inflation uncertainty. Healthy consumer spending, labor markets, and corporate earnings supported the outlook, while artificial intelligence ("AI") disruption concerns and U.S.-Iran tensions drove volatility and higher energy prices. A June ceasefire stabilized oil markets, though geopolitical tensions continued to influence Treasury yields. Meanwhile, Kevin Warsh became Fed Chair, and the Fed held rates unchanged in July amid resilient economic data.

Top contributors to performance: Security selection within the Information Technology sector contributed to relative performance over the period, driven by an allocation to SK Hynix, a manufacturer of memory chips. Security selection within the Financials sector also contributed to relative performance, driven by an allocation to OTP Bank, a financial services company.

Top detractors from performance: Security selection within the Consumer Discretionary sector detracted from relative performance over the period, driven by an allocation to Sea Limited, an e-commerce company. Security selection within the Communication Services sector also detracted from relative performance, driven by an allocation to Bharti Airtel, a telecommunications company.

How did the Fund perform last year and what affected its performance?

For the fiscal year ended July 31, 2026, the Fund returned 6.55%, reflecting performance at the net asset value (NAV), with all distributions reinvested, compared to the 5.26% return of a securities market index with investment characteristics similar to those of the Fund, the Bloomberg Municipal Bond Index. The Fund's broad-based securities market index, the Bloomberg U.S. Aggregate Bond Index, returned 2.71% over the same period.

Positive factors for the municipal market included overall healthy demand for municipal bond funds and a strong fundamental backdrop. Negative factors included an above-average municipal bond supply that pressured the market at various times throughout the fiscal year and has created more dispersion across sectors within the municipal market.

Top contributors to performance: An overweight allocation to BBB-rated bonds contributed to relative performance. Security selection, particularly within the Tobacco sector, also contributed to relative performance.

Top detractors from performance: The Fund’s yield curve positioning, specifically an underweight allocation to longer-term bonds, detracted from relative performance. An overweight allocation to the Transportation sector also detracted from relative performance.

How did the Fund perform last year and what affected its performance?

For the fiscal year ended July 31, 2026, the Fund returned 5.06%, reflecting performance at the net asset value (NAV) of Class A shares with all distributions reinvested, compared to the 4.69% return of a securities market index with investment characteristics similar to those of the Fund, the Bloomberg U.S. Floating Rate Notes Index. The Fund's broad-based securities market index, the Bloomberg U.S. Aggregate Bond Index, returned 2.71% over the same period.

From August 2025 through July 2026, U.S. fixed income markets were supported by resilient economic growth, solid consumer spending, healthy corporate earnings and continued investment, particularly in artificial intelligence ("AI"). Markets also faced headwinds from rising inflation pressures and heightened geopolitical tensions, including the U.S.-Iran conflict and its impact on energy prices. These developments contributed to periods of elevated volatility and shifting expectations for Federal Reserve policy. Despite these challenges, credit markets remained broadly constructive, supported by resilient corporate fundamentals and continued demand for income. Overall, the period reflected a balance between economic resilience and growing concerns around inflation, geopolitical risk and potential AI-driven disruption.

Top contributors to performance: The Fund’s allocation to collateralized loan obligations was the primary contributor to relative performance. An allocation to asset-backed securities also contributed to relative performance.

Top detractors from performance: The Fund’s rates positioning detracted from relative performance. The Fund’s allocation to investment grade corporate bonds also detracted from relative performance.

How did the Fund perform last year and what affected its performance?

For the fiscal year ended July 31, 2026, the Fund returned 26.53%, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared to the 20.42% return of a securities market index with investment characteristics similar to those of the Fund, the MSCI All Country World ex USA Growth Index (Net). The Fund's broad-based securities market index, the MSCI EAFE Net Index, returned 24.33% over the same period.

Top contributors to performance: Security selection within the Information Technology sector contributed to relative performance over the period, driven by an allocation to SK Hynix, a semiconductor manufacturer. Security selection within the Financials sector also contributed to relative performance, driven by an allocation to OTP Bank, a financial services company.

Top detractors from performance: Security selection within the Materials sector detracted from relative performance over the period, driven by an allocation to Heidelberg Materials, a building materials company. Security selection within the Communication Services sector also detracted from relative performance, driven by an allocation to Meta Platforms, a technology company.

How did the Fund perform last year and what affected its performance?

For the fiscal year ended July 31, 2026, the Fund returned 5.74%, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared to the 5.56% return of a securities market index with investment characteristics similar to those of the Fund, the ICE BofA High Yield U.S. Corporate Cash Pay BB-B (1-5yrs) Index. The Fund's broad-based securities market index, the Bloomberg U.S. Aggregate Bond Index, returned 2.71% over the same period.

Over the period, U.S. fixed income markets were supported by resilient economic growth, solid consumer spending, healthy corporate earnings and continued investment, particularly in artificial intelligence. Markets also faced meaningful headwinds from rising inflation pressures and heightened geopolitical tensions, including the escalation of conflict between the U.S. and Iran and its impact on energy prices. During the fiscal year, these developments contributed to periods of elevated volatility and shifting expectations for Federal Reserve policy. Despite these challenges, credit markets remained broadly constructive, supported by resilient corporate fundamentals and continued demand for income.

Top contributors to performance: Security selection within the Energy, Capital Goods and Healthcare sectors contributed to relative performance. Credit selection within BB-rated bonds also contributed to relative performance. Allocation to convertible bonds also contributed to relative performance.

Top detractors from performance: Credit selection within Basic Industry, Retail and Automotive sectors detracted from relative performance. Allocation to bank loans also detracted from relative performance.

The following is a summary of the inputs used as of July 31, 2026 in valuing the Fund’s investments carried at fair value⁽¹⁾:

The Trust currently consists of eight funds as of July 31, 2026. This report covers the following four funds (each, a “Fund” and collectively, the “Funds”) and their respective active share classes:

Emerging Markets Equity Fund’s and International Growth Fund’s investment objective is to seek long-term capital appreciation. Investment Grade Floating Rate Fund’s investment objective is to seek a high level of current income. Short Duration High Yield Fund’s investment objective is to seek a high current income and the opportunity for capital appreciation to produce a high total return.

Each class of shares has 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, 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 each 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 Funds are investment companies and apply 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.

An operating segment is defined in ASC Topic 280 – Segment Reporting, 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 Funds is the Investment Committee of Lord, Abbett & Co. LLC (“Lord Abbett”), which represents the highest-level body responsible for evaluating each Fund’s operating performance and making decisions regarding resource allocation. The Investment Committee regularly reviews each Fund’s operating results, including investment performance and financial information, in making strategic and operational decisions.

The CODM has determined that each Fund has a single operating segment based on the fact that the CODM monitors the operating results of each Fund as a whole and that the Funds’ long-term strategic asset allocation is pre-determined in accordance with the terms of their prospectus, based on a defined investment strategy which is executed by the Funds’ portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with that presented within the Funds’ Schedules of Investments, Statements of Assets and Liabilities, Statements of Operations, Statements of Changes in Net Assets and Financial Highlights.

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. Exchange traded options and futures contracts are valued at the last quoted sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted

bid and ask prices is used. Fixed income securities are valued based on evaluated prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and the independent pricing services’ own electronic data processing techniques. Floating rate loans are valued at the average of bid and ask quotations obtained from dealers in loans on the basis of prices supplied by independent pricing services. Forward foreign currency exchange contracts are valued using daily forward exchange rates. Swaps, options and options on swaps are valued daily using independent pricing services or quotations from broker/dealers to the extent available.

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 observable inputs such as yield curves, broker quotes, observable trading activity, option adjusted spread models and other relevant information to determine the fair value of portfolio investments. The Pricing Committee may also 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 each 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. 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:

A summary of inputs used in valuing each Fund’s investments and other financial instruments as of July 31, 2026 and, if applicable, Level 3 rollforwards for the fiscal year then ended is included in each 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.

The loans in which each Fund invests may be subject to some restrictions on resale. For example, each Fund may be contractually obligated to receive approval from the Agent and/or Borrower prior to the sale of these investments. Each Fund generally has no right to enforce compliance with the terms of the loan agreement with the Borrower. As a result, each Fund assumes the credit risk of the Borrower, the selling participant and any other persons interpositioned between each Fund and the Borrower (“Intermediate Participants”). In the event that the Borrower, selling participant or Intermediate Participants become insolvent or enter into bankruptcy, each Fund may incur certain costs and delays in realizing payment or may suffer a loss of principal and/or interest.

Unfunded loan commitments represent the remaining obligation of each Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. Until demanded by the Borrower, unfunded loan commitments are not recognized as an asset on the Statements of Assets and Liabilities. Unrealized appreciation/(depreciation) on unfunded loan commitments is presented, if any, on the Statements of Assets and Liabilities and represents the mark to market of the unfunded portion of each Fund’s floating rate notes.

securities will fluctuate and assets consisting of cash and/or marketable securities (normally short-term U.S. Government or U.S. Government sponsored enterprise securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at each Fund’s custodian in order to pay for the commitment. At the time each Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the liability for the purchase and fair value of the security in determining its NAV. Each Fund, generally, has the ability to close out a purchase obligation on or before the settlement date rather than take delivery of the security. Under no circumstances will settlement for such securities take place more than 120 days after the purchase date.

Derivatives–During the fiscal year ended July 31, 2026, the Funds used derivative instruments including forward foreign currency exchange contracts, futures contracts, options and swaps contracts in connection with their investment strategies. Derivative instruments may be used as substitutes for securities in which the Funds can invest, to hedge portfolio investments or to generate income or gain to the Funds. Derivatives may also be used to manage duration, sector and yield curve exposures and credit and spread volatility.

The Funds may be subject to various risks from the use of derivatives, including the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index; counterparty credit risk related to derivatives counterparties’ failure to perform under contract terms; liquidity risk related to the potential lack of a liquid market for these contracts allowing the Funds to close out their position(s); and documentation risk relating to disagreement over contract terms. Investing in certain derivatives also results in a form of leverage and as such, the Funds’ risk of loss associated with these instruments may exceed their value, as recorded on the Funds’ Statements of Assets and Liabilities.

The Funds are party to various derivative contracts governed by International Swaps and Derivatives Association master agreements (“ISDA agreements”). The Funds’ ISDA agreements, which are separately negotiated with each dealer counterparty, may contain provisions allowing, absent other considerations, a counterparty to exercise rights, to the extent not otherwise waived, against the Funds in the event the Funds’ net assets decline over time by a pre-determined percentage or fall below a pre-determined floor. The ISDA agreements may also contain provisions allowing, absent other conditions, the Funds to exercise rights, to the extent not otherwise waived, against a counterparty (e.g., decline in a counterparty’s credit rating below a specified level). Such rights for both a counterparty and the Funds often include the ability to terminate (i.e., close out) open contracts at prices which may favor a counterparty, which could have an adverse effect on the Funds. The ISDA agreements give the Funds and a counterparty the right, upon an event of default, to close out all transactions traded under such agreements and to net amounts owed or due across all transactions and offset such net payable or receivable against collateral posted to a segregated account by one party for the benefit of the other.

Counterparty credit risk may be mitigated to the extent a counterparty posts additional collateral for mark-to-market gains to the Funds.

Forward Foreign Currency Exchange Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below were exposed to foreign currency risks associated with some or all of their portfolio investments and used forward foreign currency exchange contracts to hedge or manage certain of these exposures as part of an investment strategy. Forward foreign

currency exchange contracts represent obligations to purchase or sell foreign currency on a specified future date at a price fixed at the time the contracts are entered into. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without the delivery of the foreign currency.

The values of the forward foreign currency exchange contracts are adjusted daily based on the applicable exchange rate of the underlying currency. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract settlement date. When the forward foreign currency exchange contract is closed, the Funds record a realized gain or loss equal to the difference between the value at the time the contract was opened and the value at the time it was closed. The Funds also record a realized gain or loss, upon settlement, when a forward foreign currency exchange contract offsets another forward foreign currency exchange contract with the same counterparty.

The Funds’ forward foreign currency exchange contracts are subject to master netting arrangements (the right to close out all transactions with a counterparty and net amounts owed or due across transactions).

The Funds may be required to post or receive collateral for non-deliverable forward foreign currency exchange contracts.

Futures Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below entered into futures contracts to manage and hedge interest rate risk associated with portfolio investments. During the fiscal year ended July 31, 2026, the Funds also purchased futures contracts to invest incoming cash in the market or sold futures in response to cash outflows, thereby simulating an invested position in the underlying index while maintaining a cash balance for liquidity. Futures contracts provide for the delayed delivery of the underlying instrument at a fixed price or are settled for a cash amount based on the change in the value of the underlying instrument at a specific date in the future. Upon entering into a futures contract, the Funds are required to deposit with the broker, cash or securities in an amount equal to a certain percentage of the contract amount, which is referred to as the initial margin deposit. Subsequent payments, referred to as variation margin, are made or received by the Funds periodically and are based on changes in the market value of open futures contracts. Changes in the market value of open futures contracts are recorded as Net change in unrealized appreciation/(depreciation) on futures contracts on the Statements of Operations. Realized gains or losses, representing the difference between the value of the contract at the time it was opened and the value at the time it was closed, are reported on the Statements of Operations at the closing or expiration of the futures contract. Securities deposited as initial margin are designated on the Schedules of Investments, while cash deposited, which is considered restricted, is recorded on the Statements of Assets and Liabilities. A receivable from and/or a payable to brokers for the daily variation margin is also recorded on the Statements of Assets and Liabilities.

The use of futures contracts exposes the Funds to equity price, foreign exchange and interest rate risks. The Funds may be subject to the risk that the change in the value of the futures contract may not correlate perfectly with the underlying instrument. Use of long futures contracts subjects the Funds to risk of loss in excess of the amounts shown on the Statements of Assets and Liabilities, up to the notional amount of the futures contracts. Use of short futures contracts subjects the Funds to unlimited risk of loss. The Funds may enter into futures contracts only on exchanges or boards of trade. The exchange or board of trade acts as the counterparty to each futures transaction; therefore, the Funds’ credit risk is limited to failure

of the exchange or board of trade. Under some circumstances, futures exchanges may establish daily limits on the amount that the price of a futures contract can vary from the previous day’s settlement price, which could effectively prevent liquidation of positions.

The Funds’ futures contracts are not subject to master netting arrangements (the right to close out all transactions traded with a counterparty and net amounts owed or due across transactions).

Swap Contracts–The Funds may engage in swap transactions to manage credit and interest rate (e.g., duration, yield curve) risks within their respective portfolios. Swap transactions are contracts negotiated over-the-counter (“OTC”) between a fund and a counterparty or are centrally cleared (“centrally cleared swaps”) through a central clearinghouse managed by a Futures Commission Merchant (“FCM”) that exchange investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals.

Upfront payments made and/or received by the Funds are recorded as assets or liabilities, respectively, on the Statements of Assets and Liabilities and are amortized over the term of the swap. The value of OTC swap contract agreements are recorded as either an asset or a liability on the Statements of Assets and Liabilities at the beginning of the measurement period. Upon entering into a centrally cleared swap, the Funds are required to deposit with the FCM cash or securities, which is referred to as initial margin deposit. Securities deposited as initial margin are designated on the Schedules of Investments, while cash deposited, which is considered restricted, is reported as Deposits with brokers for swap contracts collateral on the Statements of Assets and Liabilities. Daily changes in valuation of centrally cleared swaps, if any, are recorded as a variation margin receivable or payable on the Statements of Assets and Liabilities. The change in the value of swaps, including accruals of periodic amounts of interest to be paid or received on swaps, is reported as Net change in unrealized appreciation/ (depreciation) on swap contracts on the Statements of Operations. A realized gain or loss is recorded upon payment or receipt of a periodic payment or payment made upon termination of a swap agreement.

The central clearinghouse acts as the counterparty to each centrally cleared swap transaction; therefore credit risk is limited to the failure of the clearinghouse.

The Funds’ OTC swap contract agreements are subject to master netting arrangements.

Credit Default Swap Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below entered into credit default swaps to simulate long and/or short bond positions or to take an active long and/or short position with respect to the likelihood of a default or credit event by the issuer of the underlying reference obligation.

The underlying reference obligation may be a single issuer of corporate or sovereign debt, a basket of issuers or a credit index. A credit index is a list of credit instruments or exposures that reference a fixed number of obligors with shared characteristics that represents some part of the credit market as a whole. Index credit default swaps have standardized terms including a fixed spread and standard maturity dates. The composition of the obligations within a particular index changes periodically.

Credit default swaps involve one party, the protection buyer, making a stream of payments to another party, the protection seller, in exchange for the right to receive a contingent payment if there is a credit event related to the underlying reference obligation. In the event that the reference obligation matures prior to the termination date of the contract, a similar security

will be substituted for the duration of the contract term. Credit events are defined under individual swap agreements and generally include bankruptcy, failure to pay, restructuring, repudiation/moratorium, obligation acceleration and obligation default.

If a credit event occurs, the Funds, as protection sellers, would be obligated to make a payment, which may be either: (i) a net cash settlement equal to the notional amount of the swap less the auction value of the reference obligation or (ii) the notional amount of the swap in exchange for the delivery of the reference obligation. Selling protection effectively adds leverage to the Fund’s portfolio up to the notional amount of swap agreements. The notional amount represents the maximum potential liability under a contract and is not reflected on the Statements of Assets and Liabilities. Potential liabilities under these contracts may be reduced by: the auction rates of the underlying reference obligations; upfront payments received at the inception of a swap; and net amounts received from credit default swaps purchased with identical reference obligations.

Inflation-Linked Swap Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below entered into inflation-linked derivatives, such as Consumer Price Index swap contract agreements (“CPI swap contracts”). A CPI swap contract is a contract in which one party agrees to pay a fixed rate in exchange for a variable rate, which is the rate of change in the CPI during the life of the contract. Payments are based on a notional amount of principal. Each Fund will normally enter into CPI swap contracts on a zero coupon basis, meaning that the floating rate will be based on the cumulative CPI during the life of the contract, and the fixed rate will compound until the swap contract’s maturity date, at which point the payments are netted. The swap contracts are valued daily and any unrealized gain/(loss) is included in the Net change in unrealized appreciation/(depreciation) on swap contracts in the Funds’ Statements of Operations. A liquidation payment received or made at the termination or maturity of the swap contract is recorded in realized gain/(loss) and is included in Net realized gain/(loss) on swap contracts in the Funds’ Statements of Operations. Daily changes in valuation of centrally cleared CPI swap contracts, if any, are recorded as a receivable or payable for the change in value as appropriate (“variation margin”) on the Statements of Assets and Liabilities. For the centrally cleared CPI swap contracts, there was minimal counterparty risk to the Funds since such CPI swap contracts entered into were traded through a central clearinghouse, which guarantees against default.

Interest Rate Swap Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below entered into interest rate swap contracts to manage fund exposure to interest rates or to either preserve or generate a return on a particular investment or portion of their portfolios. These are agreements between counterparties to exchange periodic interest payments based on interest rates. One cash flow stream will typically be a floating rate payment based upon a specified interest rate, while the other is typically based on a fixed interest rate.

Total Return Swap Contracts–During the fiscal year ended July 31, 2026, the Funds listed in the tables below entered into total return swap contract agreements to obtain exposure to a security or market without owning such security or investing directly in that market. The Funds may agree to make payments that are the equivalent of interest in exchange for the right to receive payments equivalent to any appreciation in the value of an underlying security, index or other asset, as well as receive payments equivalent to any distributions made on that asset, over the term of the swap contract. If the value of the asset underlying a total return swap contract declines over the term of the swap contract, the Funds also may be required to pay an amount equal to that decline in value to their counterparty.

Options–During the fiscal year ended July 31, 2026, the Funds listed in the tables below purchased over-the-counter put or call options on securities, stock indices, currencies and other financial instruments for hedging purposes, to enhance portfolio returns and reduce overall volatility.

When a Fund writes (sells) an option, an amount equal to the premium received by each Fund is recorded as a liability in the Statements of Assets and Liabilities. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When an option expires, each Fund realizes a gain on the option to the extent of the premium received. Premiums received from writing options which are exercised or closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option on a security is exercised, the premium reduces the cost basis of the security purchased by each Fund. If a call option is exercised, the premium is added to the proceeds of the security sold to determine the realized gain or loss. Each Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the underlying investment. Other risks include the possibility of an illiquid options market or the inability of the counterparties to fulfill their obligations under the contracts.

Put and call options purchased are accounted for in the same manner as portfolio securities. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain or loss when the underlying transaction is executed. The risk associated with purchasing an option is that each Fund pays a premium whether or not the option is exercised. Additionally, each Fund bears the risk of loss of the premium and change in market value should the counterparty not perform under the contract. Realized and net change in unrealized gains and losses on purchased options are included in Net realized and Net change in unrealized appreciation/ (depreciation) on investments, respectively, in the Funds’ Statements of Operations.

Summary of Derivatives Information–As of July 31, 2026, the Funds in the tables below had the following derivatives at fair value, grouped into appropriate risk categories and respective location on the Statements of Assets and Liabilities:

The following tables present the effect of derivatives for each Fund on the Statements of Operations for the fiscal year ended July 31, 2026:

Disclosures About Offsetting Assets and Liabilities–FASB requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the Statements of Assets and Liabilities, and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by the counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Funds’ accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the Statements of Assets and Liabilities across transactions between the Funds and the applicable counterparty.

The Trust has a management fee agreement with Lord Abbett, pursuant to which Lord Abbett provides each 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 each Fund’s investment portfolio. The management fee is accrued daily and payable monthly.

The management fee is based on each Fund’s average daily net assets at the following annual rates:

For the fiscal year ended July 31, 2026, the effective management fee, net of any applicable waivers, was at the following annualized rate of each Fund’s average daily net assets:

In addition, Lord Abbett provides certain administrative services to each Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of each Fund’s average daily net assets. The fund administration fee is accrued daily and payable monthly.

Lord Abbett voluntarily waived certain fees and expenses during the fiscal year ended July 31, 2026:

For the fiscal year ended July 31, 2026 and continuing through November 30, 2026, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit the total net annual operating expenses, excluding certain of the Funds’ expenses, to the following annual rates:

All contractual fee waivers and expense reimbursement agreements between the Funds and Lord Abbett may be terminated only upon the approval of the Board.

Each Fund has adopted a distribution plan with respect to Class A, C, F, 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:

Class F3, Class I, Class R5 and Class R6 shares do not have a distribution plan.

The Distributor received the following commissions on sales of shares of the Funds, after concessions were paid to authorized dealers, during the fiscal year ended July 31, 2026:

The Distributor received the following amounts of CDSCs for the fiscal year ended July 31, 2026:

One Trustee and certain of the Trust’s officers have an interest in Lord Abbett.

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.

The tax character of distributions paid during the fiscal year ended July 31, 2026 was as follows:

The tax character of distributions paid during the fiscal year ended July 31, 2025 was as follows:

As of July 31, 2026, the components of distributable earnings/(loss) on a tax basis were as follows:

Net capital losses recognized by the Funds may be carried forward indefinitely and retain their character as short-term and/or long-term losses. Capital losses incurred that will be carried forward are as follows:

As of July 31, 2026, the tax cost of investments and the breakdown of unrealized appreciation/(depreciation) for each Fund are shown below. The difference between book-basis and tax basis unrealized appreciation/(depreciation) is attributable to the tax treatment of certain securities, other financial instruments, amortization of premium, and wash sales.

Permanent items identified, as shown below, have been reclassified among the components of net assets based on their tax treatment. The permanent differences are primarily attributable to tax treatment of certain distributions and net operating loss.

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended July 31, 2026 were as follows:

Each 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 July 31, 2026, the Funds did not engage in cross-trade purchases or sales.

The Trust’s officers and one Trustee, who are associated with Lord Abbett, do not receive any compensation from the Trust for serving in such capacities. Independent Trustees’ 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 Trustees under which Independent Trustees may elect to defer receipt of a portion of Trustees’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the Funds. Such amounts and earnings accrued thereon are included in Trustees’ fees in the Statements of Operations and in Trustees’ fees payable in the Statements of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

For the period ended June 4, 2026, the Funds 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 $1.675 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, $300 million, $700 million or $1 billion, in each case based on past borrowings and likelihood of future borrowings, among other factors.

Effective June 5, 2026, the Participating Funds renewed the Syndicated Facility for $1.8 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, $500 million, $700 million or $1 billion, in each case based on past borrowings and likelihood of future borrowings, among other factors. The maturity date of the Syndicated Facility is June 4, 2027.

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 5, 2026, 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. The maturity date of the Bilateral Facility is June 4, 2027.

Interest associated with these credit facilities is charged to each Fund based on its borrowings generally at an amount above the Federal Funds rate or at the negotiated rate for swing line loans. In addition, there is a fee computed at an annual rate of 0.20% on the daily unused portion of the Syndicated Facility which is allocated among the Participating Funds at the end of each quarter and is included with Other Expenses on the Statements of Operations. There is no fee associated with the unused portion of the Bilateral Facility.

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 July 31, 2026, the Funds did not utilize the Syndicated Facility or Bilateral Facility.

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 each 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 July 31, 2026, the Funds did not participate as a borrower or lender in the Interfund Lending Program.

SSB is the Funds’ custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating each Fund’s NAV.

The Funds have 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 Funds’ 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 Funds on the next business day. As with other extensions of credit, the Funds may experience a delay in the recovery of their securities or incur a loss should the borrower of the securities breach its agreement with the Funds 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 each Fund’s Statement of Operations.

The initial collateral received by the Funds 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 Funds will bear the risk of loss with respect to the investment of the cash collateral. The advantage of such loans is that the Funds continue 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 July 31, 2026, the market value of securities loaned and collateral received were as follows:

Each of the Investment Grade Floating Rate Fund and Short Duration High Yield Fund is subject to the general risks and considerations associated with investing in debt securities and to the changing prospects of individual companies and/or sectors in which the Funds invest. The value of an investment will change as interest rates fluctuate and in response to market movements. When interest rates rise, the prices of debt securities are likely to decline; when rates fall, such prices tend to rise. Longer-term debt securities are usually more sensitive to interest rate changes. There is also the risk that an issuer of a debt security will fail to make timely payments of principal or interest to a Fund, a risk that is greater with high-yield securities (sometimes called “lower-rated bonds” or “junk bonds”), in which the Funds may substantially invest. Some issuers, particularly of high-yield securities, may default as to principal and/or interest payments after a fund purchases its securities. A default, or concerns in the market about an increase in the risk of default, may result in losses to the Funds. High-yield securities are subject to greater price fluctuations, as well as additional risks. The market for below investment grade securities may be less liquid, which may make such securities more difficult to sell at an acceptable price, especially during periods of financial distress, increased market volatility, or significant market decline.

Each Fund is subject to the general risks and considerations associated with equity investing. The value of the Funds’ investments will fluctuate in response to movements in the equity securities markets in general and to the changing prospects of individual companies in which the Funds invest. If a 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.

Large company stocks, in which the International Growth Fund may invest, may perform differently than the market as a whole and other types of stocks, such as small company stocks.

Each Fund is subject to the risks of investing in foreign securities. Foreign securities may pose greater risks than domestic securities, including greater price fluctuations, economic, political, and social instability and subject to less government supervision, lack of transparency, inadequate regulatory and accounting standards, foreign taxes, and higher transaction costs. The securities of foreign companies also may be subject to inadequate exchange control regulations, the imposition of economic sanctions, threat thereof 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. Foreign investments also may be affected by

changes in currency rates or currency controls. These risks are generally greater for securities issued by companies in emerging market countries.

Each of the Investment Grade Floating Rate Fund and Short Duration High Yield Fund is subject to the risk of investing in securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities (such as the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), or the Federal Home Loan Mortgage Corporation (“Freddie Mac”)). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. Government related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government would provide financial support to its agencies and instrumentalities if not required to do so by law. Consequently, the Funds may be required to look principally to the agency issuing or guaranteeing the obligation.

The mortgage-related and asset-backed securities in which the Investment Grade Floating Rate Fund and Short Duration High Yield Fund may invest may be particularly sensitive to changes in prevailing interest rates, and economic conditions, including delinquencies and/or defaults. These changes can affect the value, income, and/or liquidity of such positions. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive a Fund of income payments above current market rates. Alternatively, rising interest rates may cause prepayments to occur at a slower-than expected rate, extending the duration of a security and typically reducing its value. The payment rate will thus affect the price and volatility of a mortgage-related security. In addition, a Fund may invest in non-agency asset backed and mortgage related securities, which are issued by private institutions, not by government-sponsored enterprises.

Each of the Emerging Markets Equity Fund and International Growth Fund is subject to the risks of investing in growth stocks. Growth stocks typically trade at higher multiples of current earnings than other stocks. Growth stocks often are more sensitive to market fluctuations than other securities because their market prices are highly sensitive to future earnings expectations. At times when it appears that these expectations may not be met, prices of growth stocks typically fall. Growth stocks may be more volatile than securities of slower-growing issuers.

The Short Duration High Yield Fund may invest in convertible securities, which have both equity and fixed income risk characteristics, including market, credit, liquidity, and interest rate risks. Generally, convertible securities offer lower interest or dividend yields than non-convertible securities of similar quality and less potential for gains or capital appreciation in a rising equity securities market than equity securities. They tend to be more volatile than other fixed income securities and the market for convertible securities may be less liquid than the markets for stocks or bonds. A significant portion of convertible securities have below investment grade credit ratings and are subject to increased credit and liquidity risks.

Each Fund is subject to the risks associated with derivatives, which may be different from and greater than the risks associated with directly investing in securities. Derivatives may be subject to risks such as liquidity risk, leveraging risk, interest rate risk, market risk, and credit risk. Illiquid securities may lower the Funds’ returns since the Funds may be unable to sell these securities at their desired time or price. Derivatives also may involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the value of the underlying asset, rate or index. Whether a Fund’s use of derivatives is successful may depend on, among other things, the Fund’s ability to correctly

forecast market movements and other factors. Losses may also arise from the failure of a derivative counterparty to meet its contractual obligations. If the Fund incorrectly forecasts these and other factors, its performance could suffer. The Fund’s use of derivatives could result in a loss exceeding the amount of the Fund’s investment in these instruments.

The Investment Grade Floating Rate Fund and Short Duration High Yield Fund may invest in loans, which include, among other things, loans to U.S. or foreign corporations, partnerships, other business entities, or to U.S. and non-U.S. governments. Each Fund may invest in fixed rate and variable rate loans and floating or adjustable rate loans, including bridge loans, novations, assignments, and participations, which are subject to increased credit and liquidity risks. Floating rate or adjustable rate senior loans are subject to increased credit and liquidity risks. The loans in which the Short Duration High Yield Fund invests will usually be rated below investment grade or may also be unrated. Below investment grade loans, as in the case of high-yield debt securities, or junk bonds, are usually more credit sensitive than interest rate sensitive, although the value of these instruments may be impacted by broader interest rate swings in the overall fixed income market. The Short Duration High Yield Fund may also invest in, or obtain exposure to, obligations that may be “covenant-lite,” which means such obligations lack certain financial maintenance covenants. Should a loan held by the Fund begin to deteriorate in quality, the Fund’s ability to negotiate with the borrower may be delayed under a covenant-lite loan compared to a loan with full maintenance covenants. This may in turn delay the Fund’s ability to seek to recover its investment. The Investment Grade Floating Rate Fund may also invest in, or obtain exposure to, collateralized loan obligations (“CLOs”) and may be subject to the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments, and include interest rate risk, credit risk, liquidity risk, prepayment risk, and the risk of default of the underlying asset, among others.

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 a 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 each Fund’s 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 each 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 each Fund and its service providers, adversely affect the value and liquidity of each Fund’s investments and negatively impact each Fund’s performance and your investment in each Fund.

We have audited the accompanying statements of assets and liabilities of Lord Abbett Trust I comprising the Lord Abbett Emerging Markets Equity Fund, Lord Abbett International Growth Fund, Lord Abbett Investment Grade Floating Rate Fund, and Lord Abbett Short Duration High Yield Fund (the “Funds”), including the schedules of investments, as of July 31, 2026, the related statements 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 for Lord Abbett International Growth Fund and Lord Abbett Short Duration High Yield Fund, and for the periods indicated in the table below for Lord Abbett Emerging Markets Equity Fund and Lord Abbett Investment Grade Floating Rate Fund, 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 each of the funds constituting Lord Abbett Trust I as of July 31, 2026, and the results of their operations for the year then ended, the changes in their 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 (or for the periods listed in the table below), in conformity with accounting principles generally accepted in the United States of America.

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ 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 Funds 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 Funds are not required to have, nor were we engaged to perform, an audit of their 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 Funds’ 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 July 31, 2026, 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.

We have served as the auditor of one or more Lord Abbett Family of Funds’ investment companies since 1932.

Remuneration paid to trustees, officers, and others is included in “Trustees’ Remuneration” under Item 7 of this Form N-CSR.

The Board, including all of the Trustees who are not “interested persons” of the Company or of Lord Abbett, as defined in the Investment Company Act of 1940, as amended (the “Independent Trustees”), annually considers whether to approve the continuation of the existing management agreement between each Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about each Fund’s investment performance compared to the performance of a benchmark. Before making its decision as to each Fund, the Board had the opportunity to ask questions and request further information, taking into account its knowledge of Lord Abbett gained through its meetings and discussions. The Independent Trustees also met with their independent legal counsel in various private sessions at which no representatives of management were present.

The materials received by the Board as to each Fund included, but were not limited to: (1) for each Fund, information provided by Broadridge Financial Solutions (“Broadridge”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Broadridge, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of a benchmark; (2) information provided by Broadridge regarding the expense ratios, contractual and actual management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability to Lord Abbett of providing management and administrative services to the Fund; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund (in the case of Short Duration High Yield Fund); and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management and Related Services Generally. The Board considered the services provided by Lord Abbett to each Fund, including investment research, portfolio management, risk oversight and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements and investments undertaken to enhance its compliance oversight. The Board

Statement Regarding Basis for Approval of Investment Advisory Contract (continued)

also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business, although the Board was mindful that other conflicts of interest may exist. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to each Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. The Board observed that differences in fee rates between these clients and the Lord Abbett Funds are not uniform when examined on a fund-by-fund basis, suggesting that differences in the pricing of investment management services to these clients may reflect a variety of factors, including historical competitive forces operating in separate marketplaces. The Board considered the fact that in many instances, fee rates are higher on average for mutual fund clients than for other clients. The Board did not rely on these comparisons to any significant extent in reaching their decision. After reviewing these and related factors, the Board concluded that each Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed each Fund’s investment performance in relation to that of its performance peer group and a benchmark as of various periods ended June 30, 2025. As to Short Duration High Yield Fund, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-, three-and five-year periods. As to International Growth Fund, the Board observed that the Fund’s investment performance was below the median of the performance peer group for the one-and three-year periods. As to Emerging Markets Equity Fund, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the one- and three-year periods. As to Investment Grade Floating Rate Fund, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year period. In each case, the Board considered Lord Abbett’s explanation of the Fund’s performance. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board, and the willingness of Lord Abbett to take steps intended to improve performance when appropriate. After reviewing these and other factors, including those described below, the Board concluded that each Fund’s Agreement should be continued.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to each Fund, in light of its investment objective and strategy, and other services provided to each Fund by Lord Abbett. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s staff, the resources made available to them, Lord Abbett’s investment methodologies and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s oversight of third-party service providers, including each Fund’s transfer agent and custodian.

Statement Regarding Basis for Approval of Investment Advisory Contract (continued)

Expenses. The Board considered the expense level of each Fund, including the contractual and actual management fee rates, and the expense levels of the Fund’s expense peer group and the nature of the Fund’s expense peer group. It also considered how each of the expense level and the actual management fee rates of each Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. As to each Fund, the Board observed that the net total expense ratio and the actual management fee of the Fund were both below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the management fee schedule in place for each Fund was reasonable in light of all of the factors it considered, including the nature, quality and extent of services provided by Lord Abbett.

Profitability. As to each Fund, the Board considered the level of Lord Abbett’s operating margin in managing the Fund, including the administrative services it provides to the Fund, and reviewed Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether each Fund was profitable to Lord Abbett in connection with the Fund’s operation, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board considered Lord Abbett’s profit margins excluding Lord Abbett’s marketing and distribution expenses. The Board also considered Lord Abbett’s profit margins, without those exclusions, in comparison with available industry data and how those profit margins could affect Lord Abbett’s ability to recruit and retain personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified personnel to provide services to each Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to each Fund was not excessive.

Economies of Scale. As to each Fund, the Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from any such economies of scale, and whether, to the extent there were economies of scale, there was potential for realization of any further economies of scale. The Board also considered information provided by Lord Abbett regarding how it shares any potential economies of scale through its investments in its businesses supporting the Funds. The Board also considered each Fund’s existing management fee schedule, with one or more contractual breakpoints in the level of management fee, and, with respect to Emerging Markets Equity Fund and International Growth Fund, the Fund’s expense limitation agreement. Based on these considerations, the Board concluded that any economies of scale were adequately addressed in respect of each Fund.

Other Benefits to Lord Abbett. As to each Fund, the Board considered the amount and nature of the fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services, such as the fee that Lord Abbett receives from each Fund for providing administrative services to the Fund. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with each Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, that the Distributor may retain a portion of the 12b-1 fees it receives, and that the Distributor receives a portion of the sales charges on sales and redemptions of some classes of shares of the

Statement Regarding Basis for Approval of Investment Advisory Contract (concluded)

Lord Abbett Funds. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett has entered into revenue sharing arrangements with certain entities that distribute shares of the Lord Abbett Funds. The Board also took into consideration the investment research that Lord Abbett receives as a result of client brokerage transactions, including its mutual fund clients.

Alternative Arrangements. As to each Fund, the Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of each Fund and its shareholders and voted unanimously to approve the continuation of the Agreement on behalf of each Fund. As to each Fund, in considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

The following is a summary of the inputs used as of July 31, 2026 in valuing the Fund’s investments carried at fair value⁽¹⁾:

A reconciliation of Level 3 investments is presented when the Fund has a material amount of Level 3 investments at the beginning or end of the year in relation to the Fund’s net assets.

Lord Abbett Trust I (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company and was organized as a Delaware statutory trust on May 1, 2001. The Trust consists of eight funds as of July 31, 2026. This report covers Lord Abbett Diversification Shares: Enhanced Municipal Yield Completion Fund (the “Fund”). The Fund is diversified within the meaning of the 1940 Act. The Fund commenced operations on April 9, 2024.

Shares of the Fund may be purchased only by or on behalf of separately managed account clients. Lord, Abbett & Co. LLC (“Lord Abbett”) has an agreement with the managed account program sponsor, or directly with the client, to provide advisory and administrative and other similar services for compensation to the managed account.

The Fund’s investment objective is to seek a high level of income exempt from U.S. federal income tax.

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.

The CODM for the Fund is the Investment Committee of Lord Abbett, which represents the highest-level body responsible for evaluating the Fund’s operating performance and making decisions regarding resource allocation. The Investment Committee regularly reviews the Fund’s operating results, including investment performance and financial information, in making strategic and operational decisions.

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.

The Fund does not pay a management fee to Lord Abbett under the management fee agreement between the Trust and Lord Abbett.

For the fiscal year ended July 31, 2026, Lord Abbett has contractually agreed to waive all fees and to bear and/or reimburse all expenses of the Fund, but excluding acquired fund fees and expenses, brokerage fees and commissions and other portfolio transaction expenses, investment-related expenses including, but not limited to costs of borrowing money and other leveraging methods, interest-related expenses, taxes, governmental fees, expenses related to litigation and potential litigation, and extraordinary expenses. This agreement will continue in effect, unless sooner terminated by the Trust’s Board, for so long as Lord Abbett serves as the investment adviser to the Fund pursuant to the management agreement between the Trust and Lord Abbett.

One Trustee and certain of the Trust’s officers have an interest in Lord Abbett.

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.

The tax character of distributions paid during the fiscal year ended July 31, 2026 was as follows:

The tax character of distributions paid during the fiscal year ended July 31, 2025 was as follows:

As of July 31, 2026, the components of distributable earnings/(loss) on a tax basis were as follows:

As of July 31, 2026, the tax cost of investments and the breakdown of unrealized appreciation/(depreciation) for the Fund are shown below. The difference between book-basis and tax basis unrealized appreciation/(depreciation) is attributable to the tax treatment of certain securities, other financial instruments, amortization of premium, and wash sales.

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended July 31, 2026 were as follows:

There were no purchases or sales of U.S. Government securities during the fiscal year ended July 31, 2026.

The Trust’s officers and one Trustee, who are associated with Lord Abbett, do not receive any compensation from the Trust for serving in such capacities. Independent Trustees’ 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 Trustees under which Independent Trustees may elect to defer receipt of a portion of Trustees’ 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 Trustees’ fees in the Statement of Operations and in Trustees’ 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.

For the period ended June 4, 2026, 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 $1.675 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, $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 4, 2026, 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.

Interest associated with these credit facilities is charged to the Fund based on its borrowings generally at an amount above the Federal Funds rate or at the negotiated rate for swing line

loans. In addition, there is a fee computed at an annual rate of 0.20% on the daily unused portion of the Syndicated Facility which is allocated among the Participating Funds at the end of each quarter and is included with Other Expenses on the Statement of Operations. There is no fee associated with the unused portion of the Bilateral Facility.

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 July 31, 2026, the Fund did not utilize the Syndicated Facility or Bilateral Facility.

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 July 31, 2026, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

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.

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.

The Fund’s performance and the fair value of its investments will vary in response to changes in interest rates and other market factors. As interest rates rise, the Fund’s investments typically will lose value. This risk is usually greater for long-term bonds and particularly for TOB Residuals. As a result, the Fund, to the extent it invests in long-term bonds and TOB Residuals, is subject to such greater market risk. During periods of falling interest rates, the Fund’s investments may gain value.

There is the risk that an issuer of a municipal bond may fail to make timely payments of principal or interest to the Fund, a risk that is greater with municipal bonds rated below investment grade (sometimes called “lower rated bonds” or “junk bonds”). Some issuers, particularly of junk bonds, may default as to principal and/or interest payments after the Fund purchases their securities. A default, or concerns in the market about an increase in risk of default or the deterioration in the creditworthiness of an issuer, may result in losses to the Fund. Junk bonds are considered predominantly speculative by traditional investment standards. In addition, the market for lower rated municipal bonds generally is less liquid and more volatile than the market for higher rated bonds, subjecting them to greater price fluctuations which could result in losses.

The Fund may invest in private activity bonds (sometimes called “AMT paper”). The credit quality of AMT paper usually is directly related to the credit standing of the private user of the facilities.

The Fund may invest in TOB Residuals. A TOB Residual, sometimes referred to as an inverse floater or a residual interest bond, is a type of derivative debt instrument with a floating or variable interest rate that moves in the opposite direction of the interest rate on another specific fixed-rate security. Changes in the interest rate on the specific fixed-rate security inversely affect the residual interest paid on the TOB Residual, with the result that when interest rates rise, TOB Residuals’ interest payments are lowered and their value falls faster than securities similar to the specific fixed-rate security. When interest rates fall, not only do TOB Residuals generally provide interest payments that are higher than securities similar to the specific fixed-rate security, but their values generally also rise faster than such similar securities.

The Fund may purchase securities on a forward commitment or when-issued basis. Delivery and payment for such securities can take place a month or more after the transaction date. During this period such securities are subject to market fluctuations.

A widespread health crisis, such as a global pandemic, could cause substantial market volatility, impact the ability to complete redemptions, and adversely impact the Fund’s 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.

To the shareholders of Lord Abbett Diversification Shares: Enhanced Municipal Yield Completion Fund and the Board of Trustees of Lord Abbett Trust I

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Lord Abbett Diversification Shares: Enhanced Municipal Yield Completion Fund (the “Fund”), one of the funds constituting Lord Abbett Trust I, as of July 31, 2026, 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 the years ended July 31, 2026, 2025, and the period from April 9, 2024 (commencement of operations) through July 31, 2024, 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 July 31, 2026, 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 the years ended July 31, 2026, 2025, and the period from April 9, 2024 (commencement of operations) through July 31, 2024 in conformity with accounting principles generally accepted in the United States of America.

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.

We have served as the auditor of one or more Lord Abbett Family of Funds’ investment companies since 1932.

Remuneration paid to trustees, officers, and others is included in “Trustees’ Remuneration” under Item 7 of this Form N-CSR.

The Board, including all of the Trustees who are not “interested persons” of the Fund or of Lord Abbett, as defined in the Investment Company Act of 1940, as amended (the “Independent Trustees”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of a benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its knowledge of Lord Abbett gained through its meetings and discussions. The Independent Trustees also met with their independent legal counsel in various private sessions at which no representatives of management were present.

The materials received by the Board as to the Fund included, but were not limited to: (1) information provided by Broadridge Financial Solutions (“Broadridge”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Broadridge, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of a benchmark; (2) information provided by Broadridge regarding the expense ratios, contractual and actual management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability to Lord Abbett of providing management and administrative services to the Fund; and (8) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Statement Regarding Basis for Approval of Investment Advisory Contract (continued)

Investment Management and Related Services Generally. The Board considered the services provided by Lord Abbett to the Fund, including investment research, portfolio management, risk oversight, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements and investments undertaken to enhance its compliance oversight. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business, although the Board was mindful that other conflicts of interest may exist. The Board considered the investment advisory services provided by Lord Abbett to other clients and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and a benchmark as of the one-year period ended June 30, 2025. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year period. The Board considered Lord Abbett’s explanation of the Fund’s performance, especially the fact that, unlike most mutual funds, the Fund is used solely to facilitate the investment of a portion of a separately managed account’s investment strategy. The value of benchmark comparisons and peer group comparisons therefore is limited. The Board further considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board, and the willingness of Lord Abbett to take steps intended to improve performance when appropriate. After reviewing these and other factors, including those described below, the Board concluded that the Fund’s Agreement should be continued.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and strategy, and other services provided to the Fund by Lord Abbett. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s staff, the resources made available to them, Lord Abbett’s investment methodologies and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining personnel.

Expenses. The Board noted that the Fund is only available to separately managed account clients where Lord Abbett has an agreement with the separately managed account program sponsor, or directly with the client, to provide advisory and administrative and other similar services. The Board considered the expense level of the Fund and noted that the Fund does not pay a management or administrative fee to Lord Abbett. The Board also noted that Lord Abbett had agreed to waive fees and/or reimburse expenses of the Fund to the extent that expenses of the Fund (excluding certain items) exceed an annual rate of 0.00% of the Fund’s average net assets.

Statement Regarding Basis for Approval of Investment Advisory Contract (concluded)

Profitability. As to the Fund, the Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. The Board understood that, given that the Fund does not pay Lord Abbett an advisory or administrative fee and that Lord Abbett was obligated to pay certain expenses of the Fund, the Fund was not profitable to Lord Abbett based on revenues received from the Fund.

Economies of Scale. The Board understood that, given that the Fund does not pay Lord Abbett an advisory or administrative fee and that Lord Abbett was obligated to pay certain expenses of the Fund, the question of sharing of any economies of scale that might exist was not relevant.

Other Benefits to Lord Abbett. The Board considered the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund, including direct or indirect compensation by separately managed account program sponsors. The Board also observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of client brokerage transactions, including its mutual fund clients.

The following is a summary of the inputs used as of July 31, 2026 in valuing the Fund’s investments carried at fair value⁽¹⁾:

A reconciliation of Level 3 investments is presented when the Fund has a material amount of Level 3 investments at the beginning or end of the year in relation to the Fund’s net assets.

Lord Abbett Trust I (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company and was organized as a Delaware statutory trust on May 1, 2001. The Trust consists of eight funds as of July 31, 2026. This report covers Lord Abbett Diversification Shares: Core Completion Fund (the “Fund”). The Fund is diversified within the meaning of the 1940 Act. The Fund commenced operations on March 30, 2026.

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, Statement of Changes in Net Assets and Financial Highlights.

The Fund does not pay a management fee to Lord Abbett under the management fee agreement between the Trust and Lord Abbett.

For the period ended July 31, 2026, Lord Abbett has contractually agreed to waive all fees and to bear and/or reimburse all expenses of the Fund, but excluding acquired fund fees and expenses, brokerage fees and commissions and other portfolio transaction expenses, investment-related expenses including, but not limited to costs of borrowing money and other leveraging methods, interest-related expenses, taxes, governmental fees, expenses related to litigation and potential litigation, and extraordinary expenses. This agreement will continue in effect, unless sooner terminated by the Trust’s Board, for so long as Lord Abbett serves as the investment adviser to the Fund pursuant to the management agreement between the Trust and Lord Abbett.

One Trustee and certain of the Trust’s officers have an interest in Lord Abbett.

The tax character of distributions paid during the fiscal period ended July 31, 2026 was as follows:

As of July 31, 2026, the components of distributable earnings/(loss) on a tax basis were as follows:

The Fund is subject to the general risks and considerations associated with investing in fixed income securities and to the changing prospects of individual companies and/or sectors in which the Fund invests. The value of an investment will change as interest rates fluctuate and in response to market movements. When interest rates rise, the prices of fixed income securities are likely to decline, when interest rates fall, such prices tend to rise. Longer-term securities are usually more sensitive to interest rate changes. There is also the risk that an issuer of a fixed income security will fail to make timely payments of principal and/or interest to the Fund, a risk that is greater with high-yield bonds (sometimes called “junk bonds”) in which the Fund may invest. Some issuers, particularly of high-yield bonds may default as to principal and/or interest payments after the Fund purchases their securities. A default, or concerns in the market about an increase in risk of default may result in losses to the Fund. High-yield bonds are subject to greater price fluctuations and increase liquidity risk as well as additional risks.

The Fund’s investment exposure to foreign (which may include emerging markets) companies presents increased market, liquidity, currency, political, information and other risks. The cost of the Fund’s potential use of forward foreign currency exchange contracts varies with factors such as the currencies involved, the length of the contract period and the market conditions prevailing. The Fund is subject to the risks associated with derivatives, which may be different from and greater than the risks associated with directly investing in securities. Derivatives may be subject to risks such as liquidity risk, leveraging risk, interest rate risk, market risk, and credit risk. Illiquid securities may lower the Fund’s returns since the Fund may be unable to sell these securities at their desired time or price. Derivatives also may involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the value of the underlying asset, rate or index. Whether the Fund’s use of derivatives is successful may depend on, among other things, the Fund’s ability to correctly forecast market movements, changes in foreign exchange and interest rates, and other factors.

If the Fund incorrectly forecasts these and other factors, its performance could suffer. The Fund’s use of derivatives could result in a loss exceeding the amount of the Fund’s investment in these instruments.

The Fund may invest in swap contracts. Swap contracts are bi-lateral agreements between a fund and its counterparty. Each party is exposed to the risk of default by the other in addition to the risks associated with investing in derivatives discussed above. In addition, they may involve a small investment of cash compared to the risk assumed with the result that small changes may produce disproportionate and substantial gains or losses to the Fund.

The Fund is subject to the risks of investing in credit default swap contracts. The risks associated with the Fund’s investment in credit default swap contracts are greater than if the Fund invested directly in the reference obligation because they are subject to liquidity risk, counterparty risk, and credit risk at both the counterparty and underlying issuer levels in addition to the risks associated with investing in derivatives discussed above. The Fund’s exposure to inflation-linked investments, such as Treasury Inflation Protected Securities, may be vulnerable to changes in expectations of inflation or interest rates and there is no guarantee that the Fund’s use of these instruments will be successful.

The Fund is subject to the risks of investing in floating rate or adjustable rate senior loans, which are subject to increased credit and liquidity risks. Senior loans are business loans made to borrowers that may be U.S. or foreign corporations, partnerships or other business entities. The senior loans in which the Fund may invest may consist primarily of senior loans that are rated below investment grade or, if unrated, deemed by Lord Abbett to be equivalent to below investment grade securities. Below investment grade senior loans, as in the case of high-yield debt securities, or junk bonds, are usually more credit sensitive than interest rate sensitive, although the value of these instruments may be impacted by broader interest rate swings in the overall fixed income market.

The Fund is subject to the risk of investing in securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities (such as the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), or the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. Government-related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. Government and no assurance can be given that the U.S. Government would provide financial support to its agencies and instrumentalities if not required to do so by law. Consequently, the Fund may be required to look principally to the agency issuing or guaranteeing the obligation.

The Fund is subject to the risks of investing in asset backed securities and mortgage related securities, including those of such Government sponsored enterprises as Fannie Mae and Freddie Mac. In addition, the Fund may invest in non-agency backed and mortgage related securities, which are issued by the private institutions, not by the government-sponsored enterprises. Such securities may be particularly sensitive to changes in economic conditions, including delinquencies and/or defaults, and changes in prevailing interest rates. These changes can affect the value, income and/or liquidity of such positions. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive a Fund of income payments above current markets rates. The prepayment rate also will affect the price and volatility of a mortgage-related security. In addition, securities of government sponsored enterprises are guaranteed with respect to the timely payment of interest and principal by the particular enterprise involved, not by the U.S. Government.

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.

To the shareholders of Lord Abbett Diversification Shares: Core Completion Fund and the Board of Trustees of Lord Abbett Trust I

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Lord Abbett Diversification Shares: Core Completion Fund (the “Fund”), one of the funds constituting Lord Abbett Trust I, as of July 31, 2026, the related statement of operations, statement of changes in net assets, and financial highlights for the period from March 30, 2026 (commencement of operations) through July 31, 2026, 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 July 31, 2026, and the results of its operations, the changes in its net assets, and the financial highlights for the period from March 30, 2026 (commencement of operations) through July 31, 2026 in conformity with accounting principles generally accepted in the United States of America.

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.

We have served as the auditor of one or more Lord Abbett Family of Funds’ investment companies since 1932.
