ALGER MID CAP GROWTH PORTFOLIO

Dear Shareholders,

“Information is the resolution of uncertainty.” – Claude Shannon

At Alger, we integrate our focus on change and the uncertainty that it brings with a deep commitment to fundamental bottom-up research. In the realm of investing, where uncertainty and change are constant companions, we recognize the significance of making well-informed decisions on corporate fundamentals—such as sales, earnings, and cash flow—to seek alpha generation and long-term wealth creation. Our approach is centered on diligently gathering and analyzing information to identify companies not only with a strong potential for sustained earnings growth over the long-term, but also those adept at navigating and capitalizing on market disruption. By focusing on businesses poised to gain market share and compound their earnings growth—decisions we hope are made clearer through our deep commitment to resolving investment uncertainties with solid information— we aim to construct portfolios that are resilient in various economic scenarios, including periods of significant change. This approach is not just about avoiding risk; it is about actively seeking out opportunities where information aligns with a potential for growth amidst change. Ultimately, our goal is to enhance long-term value for our shareholders, guided by the beacon of well-resolved information in a sea of market uncertainties and ever-evolving change.

Reflecting on the fiscal year ended December 31, 2023, the narrative of the market was one of resilience and recovery, with the S&P 500 Index finishing up 26.29%. Following a turbulent 2022, in which higher interest rates dampened equity valuations, investor sentiment turned positive in 2023, driven by easing inflation, stabilizing corporate earnings, and the increasing likelihood of a soft landing (i.e., an economic slowdown without a recession). Further, a surge of enthusiasm around Artificial Intelligence ("AI") contributed to outsized returns for certain of the largest companies within the Information Technology and Communication Services sectors. Not all sectors shared in this rally, as the Energy and Utilities sectors underperformed the S&P 500 Index. As for interest rates, the yield on U.S. 10-year note started the year at 3.88%, peaked at 4.99% in mid-October, and then fell 111 basis points back to 3.88%, ending the year precisely where it began.

During the first quarter of 2023, we saw a reversal in the bearish sentiment that had marked much of the previous year. In February, the Federal Reserve (the “Fed”) slowed down its rate hikes to 25 basis point increments, a reduction from the 50 basis point hike in December 2022. In March, concerns around bank funding and liquidity emerged following the collapse of two regional banks, leading to significant deposit outflows across many regional banks. The Fed, U.S. Treasury, and Federal Deposit Insurance Corporation (FDIC) took steps to alleviate market concerns, including announcing an emergency liquidity program, guaranteeing uninsured deposits, and allowing some bank mergers and acquisitions.

Transitioning into the second quarter of 2023, U.S. economic data released in June reinforced the soft landing narrative with signs of (1) disinflation, as evidenced by the May Consumer Price Index (“CPI”) report coming in softer than expected with headline CPI posting the lowest annual increase in more than two years, (2) resilient labor markets, as May payrolls beat estimates for a 14th straight month, and (3) a stronger housing market, with builder confidence at the highest in nearly a year, housing starts at the highest in over a year, and multi-unit starts at the highest in nearly four decades.

Despite the strong rally in the first-half of 2023, U.S. equities fell during the third quarter. While investors initially embraced a continuation of prevailing narratives around AI and expectations of a soft landing in July, mounting concerns surrounding aggressive Fed policy and a sharp rise in interest rates led to declining equity prices in August and September. Moreover, the resumption of student loan payments, diminished savings from the pandemic, and higher energy prices reignited worries that a decline in U.S. consumer spending could lead to the possibility of an upcoming recession. Rising interest rates were seen as one of the largest headwinds to risk assets during the third quarter, as the yield on the U.S. 10-year note increased by 76 basis points to 4.57% and the yield on the two-year note increased nearly 20 basis points to 5.04%. While the rate of inflation decelerated meaningfully year-over- year, the monthly CPI readings for July and August rose 0.2% and 0.6%, respectively. That said, the rise in interest rates was driven more by real yields (i.e., nominal yields excluding inflation), as opposed to rising inflation expectations during the third quarter.

In the final quarter of 2023, U.S. equities experienced a strong rally, driven in large part by considerable easing in financial conditions. This shift was primarily driven by Fed officials’ acknowledgment in October that the tightening financial measures implemented throughout 2023 had reduced the need for further rate hikes. Moreover, disinflation remained a high- profile market theme throughout the quarter, as the October Core CPI report came in below consensus estimates. Further, the October Core Personal Consumption Expenditure Price Index, the Fed’s preferred inflation measure, also fell to its lowest level since March 2021. In late November, Fed Governor Christopher Waller said continued disinflation over the next several months could lead to rate cuts in 2024. The December Federal Open Market Committee (FOMC) meeting reinforced this dovish stance, as the median 2024 Fed Funds rate projection implied 75 basis points worth of easing. Additionally, consumer resilience, strong third quarter corporate earnings and an anticipated rebound in earnings growth in 2024 were other contributors to the fourth quarter market rally.

Among non-U.S. equities, developed markets saw strong performance during the fiscal twelve-month period ended December 31, 2023. Notable strength was driven by Europe avoiding an energy crisis due to a mild winter, and Japan’s economy being bolstered by well-received corporate reforms to improve governance. As such, the MSCI ACWI ex- USA rose 16.21% during the fiscal twelve-month period ended December 31, 2023, with the Information Technology and Industrials sectors showing strong results, while the Real Estate and Consumer Staples sectors saw weaker performance. Within Emerging Markets, technology focused countries like Taiwan and Korea, performed strongly as evidence of a cyclical recovery in the semiconductor industry. Moreover, India benefited from strong household consumption, moderating inflation, and increased foreign investment, as we believe the country continues to show strong structural growth from increased government spending and a growing middle class. However, there was notable weakness in China as the country faced challenges in their property sector, and weaker-than-expected economic recovery data weighed on investor sentiment throughout 2023. As such, the MSCI Emerging Markets Index was up 10.27% during the fiscal twelve-month period ended December 31, 2023. Strong performance within the Energy and Information Technology sectors was partially offset by relative weakness in the Real Estate and Consumer Discretionary sectors.

Going Forward

We continue to believe that an unprecedented level of innovation is creating compelling investment opportunities – corporations are digitizing their operations, cloud computing growth continues to support future innovation, and artificial intelligence, which, in our view, is at an inflection point, potentially enabling significant increases in productivity. In the Health Care sector, we believe that advances in surgical technologies and innovations within biotechnology offer attractive opportunities ahead. As such, we intend to continue to focus on conducting in-depth fundamental research as we seek leaders of innovation. We believe this strategy embodies Claude Shannon’s insight, obtaining information to make well- informed decisions that help our shareholders achieve their long-term investment goals.

Separately, 2024 marks Alger’s 60th anniversary in our pursuit of growth investing. Over the past six decades, we have seen much change, including change itself. We believe accelerating change is one of the key reasons why growth stocks have outperformed value investing over the past 20 years. As innovations in areas like artificial intelligence, genomics, and surgical technologies evolve, we see a bright future for our style of growth investing.

Portfolio Matters

Alger Mid Cap Growth Portfolio

The Alger Mid Cap Growth Portfolio returned 23.17% for the fiscal twelve-month ended December 31, 2023, compared to the 25.87% return of the Russell Midcap Growth Index. During the reporting period, the largest sector weightings were Information Technology and Industrials. The largest sector overweight was Real Estate and the largest sector underweight was Consumer Discretionary.

Contributors to Performance

The Materials and Real Estate sectors provided the largest contributions to relative performance. Regarding individual positions, Constellation Software Inc.; Cadence Design Systems, Inc.; Chipotle Mexican Grill, Inc.; TransDigm Group Inc.; and Palo Alto Networks, Inc. were among the top contributors to absolute performance.

Palo Alto Corporation is a leading network security vendor that specializes in multi- function “next-generation” firewall appliances which streamline protection by replacing multiple point solutions with a single, comprehensive application. The company has also expanded into cloud security through its Prisma Cloud offering, software-defined wide-area networking (SD-WAN) via Prisma SD-WAN, and secure web gateway (SWG) with Prisma Access. As a pioneer in application control technology, the company enables firewalls to implement selective usage policies for applications, rather than blocking them entirely. During the period, shares contributed to performance as the company reported better-than- expected operating results, as revenues and total billings beat analyst estimates. Management also raised fiscal 2023 guidance on total billings and free cash flow margin, underscoring its commitment to profitability and margin expansion. Separately, we believe that the surge in enthusiasm around AI helped propel shares higher. In our view, as AI and data become more important, the security needed to protect these technologies could continue to grow in importance.

Detractors from Performance

The Industrials and Financials sectors were the largest detractors from relative performance. Regarding individual positions, Insulet Corp; Paycom Software, Inc.; First Republic Bank; TransUnion; and WillScot Mobile Mini Holdings Corp. were among the top detractors from absolute performance.

 - 3 -

Insulet is a medical device company focused on commercializing its Omnipod portfolio of insulin delivery devices. The company’s Omnipod device is a tubeless insulin pump that is in the shape of a pod – this device is directly attached to a patient’s body. The key differentiator between Insulet’s insulin delivery devices and those of competitors is the tubeless feature – this enables a more discrete administration of insulin. Insulet’s Omnipod portfolio includes three key product lines: Classic Omnipod, Omnipod DASH, and Omnipod 5. The Omnipod technology is also used as a subcutaneous drug delivery system to deliver certain therapeutics. During the period, shares detracted from performance as investors became concerned about the long-term impact of GLP-1 drugs, a newer class of drugs that are highly effective in treating diabetes and obesity.

Thank you for putting your trust in Alger.

Sincerely,

Daniel C. Chung, CFA

Risk Disclosures

Investing in the stock market involves risks, including the potential loss of principal. Growth stocks may be more volatile than other stocks as their prices tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political, and economic developments. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases and similar public health threats, recessions, or other events could have a significant impact on investments. A significant portion of assets may be invested in securities of companies in related sectors, and may be similarly affected by economic, political, or market events and conditions and may be more vulnerable to unfavorable sector developments. Investing in companies of medium capitalizations involves the risk that such issuers may have limited product lines or financial resources, lack management depth, or have limited liquidity. Foreign securities involve special risks including currency fluctuations, inefficient trading, political and economic instability, and increased volatility. Active trading may increase transaction costs, brokerage commissions, and taxes, which can lower the return on investment. At times, the Portfolio may hold a large cash position, which may underperform relative to equity securities.

For a more detailed discussion of the risks associated with the Portfolio, please see the Portfolio’s prospectus.

Before investing, carefully consider the Portfolio’s investment objective, risks, charges, and expenses. For a prospectus containing this and other information about The Alger Portfolios, call us at (800) 992-3863 or visit us at www.alger.com. Read the prospectus and summary prospectus carefully before investing.

Alger Mid Cap Growth Portfolio

NOTES TO FINANCIAL STATEMENTS

NOTE 1 — General:

The Alger Portfolios (the “Fund”) is an open-end registered investment company organized as a business trust under the laws of the Commonwealth of Massachusetts. The Fund qualifies as an investment company as defined in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946 – Financial Services – Investment Companies. The Fund operates as a series company currently offering six series of shares of beneficial interest: Alger Capital Appreciation Portfolio, Alger Large Cap Growth Portfolio, Alger Growth & Income Portfolio, Alger Mid Cap Growth Portfolio, Alger Small Cap Growth Portfolio and Alger Balanced Portfolio (collectively, the “Portfolios”). These financial statements include only the Alger Mid Cap Growth Portfolio (the “Portfolio”). The Portfolio invests primarily in equity securities and has an investment objective of long-term capital appreciation. Shares of the Portfolio are available to investment vehicles for variable annuity contracts and variable life insurance policies offered by separate accounts of life insurance companies, as well as qualified pension and retirement plans.

The Portfolio only offers Class I-2 shares. After the close of business on June 3, 2022, Class S shares of the Portfolio were converted into Class I-2 shares with the same relative aggregate net asset value as the Class S shares held immediately prior to the conversion. Upon completion of the conversion, Class S shares of the Portfolio were no longer offered.

On May 23, 2023, the Board of Trustees of the Fund (the “Board”) approved the transition of the Fund’s custodian and administrator from Brown Brothers Harriman & Company (the “Custodian”) to The Bank of New York Mellon. This change is anticipated to become effective in early 2024.

NOTE 2 — Significant Accounting Policies:

(a) Investment Valuation: The Portfolio values its financial instruments at fair value using independent dealers or pricing services under policies approved by the Board. Investments held by the Portfolio are valued on each day the New York Stock Exchange (the “NYSE”) is open, as of the close of the NYSE (normally 4:00 p.m. Eastern Time).

The Board has designated, pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended (the “1940 Act”), the Portfolio’s investment adviser, Fred Alger Management, LLC (“Alger Management” or the “Investment Manager”) as its valuation designee (the “Valuation Designee”) to make fair value determinations subject to the Board’s review and oversight. The Valuation Designee has established a Valuation Committee (“Committee”) comprised of representatives of the Investment Manager and officers of the Portfolio to assist in performing the duties and responsibilities of the Valuation Designee.

The Valuation Designee has established valuation processes including but not limited to: (i) making fair value determinations when market quotations for financial instruments are not readily available in accordance with valuation policies and procedures adopted by the Board; (ii) assessing and managing material risks associated with fair valuation determinations; (iii) selecting, applying and testing fair valuation methodologies; and (iv) overseeing and evaluating pricing services used by the Portfolio. The Valuation Designee regularly reports its fair valuation determinations and related valuation information to the Board. The Committee generally meets quarterly and on an as-needed basis to review and evaluate the effectiveness of the valuation policies and procedures in accordance with the requirements of Rule 2a-5.

-20-

Alger Mid Cap Growth Portfolio

NOTES TO FINANCIAL STATEMENTS (Continued)

Investments in money market funds and short-term securities held by the Portfolio having a remaining maturity of sixty days or less are valued at amortized cost which approximates market value.

Equity securities, including traded rights, warrants and option contracts for which valuation information is readily available, are valued at the last quoted sales price or official closing price on the primary market or exchange on which they are traded as reported by an independent pricing service. In the absence of quoted sales, such securities are generally valued at the bid price or, in the absence of a recent bid price, the equivalent as obtained from one or more of the major market makers for the securities to be valued.

Securities in which the Portfolio invests may be traded in foreign markets that close before the close of the NYSE. Developments that occur between the close of the foreign markets and the close of the NYSE may result in adjustments to the closing foreign prices to reflect what the Valuation Designee, through its Committee, believes to be the fair value of these securities as of the close of the NYSE. The Portfolio may also fair value securities in other situations, for example, when a particular foreign market is closed but the NYSE is open.

FASB Accounting Standards Codification 820 – Fair Value Measurements and Disclosures (“ASC 820”) defines fair value as the price that the Portfolio would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. ASC 820 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability and may be observable or unobservable. Observable inputs are based on market data obtained from sources independent of the Portfolio. Unobservable inputs are inputs that reflect the Portfolio’s own assumptions based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

The Portfolio’s valuation techniques are generally consistent with either the market or the income approach to fair value. The market approach considers prices and other relevant information generated by market transactions involving identical or comparable assets to measure fair value. The income approach converts future amounts to a current, or discounted, single amount. These fair value measurements are determined on the basis of the value indicated by current market expectations about such future events. Inputs for Level 1 include exchange-listed prices and broker quotes in an active market. Inputs for Level 2 include the last trade price in the case of a halted security, an exchange-listed price which has been adjusted for fair value factors, and prices of closely related securities. Additional Level 2 inputs include an evaluated price which is based upon a compilation of observable market information such as spreads for fixed income and preferred securities. Inputs for Level 3 include, but are not limited to, revenue multiples, earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples, discount rates, time to exit and the probabilities of success of certain outcomes. Such unobservable market information may be obtained from a company’s financial statements and from industry studies, market data, and market indicators such as benchmarks and indexes. Because of the inherent uncertainty and often limited markets for restricted securities, the valuations assigned to such securities by the Portfolio may significantly differ from the valuations that would have been assigned by the Portfolio had there been an active market for such securities.

NOTES TO FINANCIAL STATEMENTS (Continued)

(b) Cash and Cash Equivalents: Cash and cash equivalents include U.S. dollars, foreign cash and overnight time deposits.

(c) Securities Transactions and Investment Income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recognized on the ex-dividend date and interest income is recognized on the accrual basis.

Premiums and discounts on debt securities purchased are amortized or accreted over the lives of the respective securities.

(d) Foreign Currency Transactions: The books and records of the Portfolio are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the prevailing rates of exchange on the valuation date. Purchases and sales of investment securities and income and expenses are translated into U.S. dollars at the prevailing exchange rates on the respective dates of such transactions.

Net realized gains and losses on foreign currency transactions represent net gains and losses from the disposition of foreign currencies, currency gains and losses realized between the trade dates and settlement dates of security transactions, and the difference between the amount of net investment income accrued and the U.S. dollar amount actually received. The effects of changes in foreign currency exchange rates on investments in securities are included in realized and unrealized gain or loss on investments in the accompanying Statement of Operations.

(e) Lending of Fund Securities: The Portfolio may lend its securities to financial institutions (other than to the Investment Manager or its affiliates), provided that the market value of the securities loaned will not at any time exceed one third of the Portfolio’s total assets including borrowings, as defined in its prospectus. The Portfolio earns fees on the securities loaned, which are included in interest income in the accompanying Statement of Operations. In order to protect against the risk of failure by the borrower to return the securities loaned or any delay in the delivery of such securities, the loan is collateralized by cash or securities that are maintained with the Custodian, in an amount equal to at least 102% of the current market value of U.S. loaned securities or 105% for non-U.S. loaned securities. The market value of the loaned securities is determined at the close of business of the Portfolio. Any required additional collateral is delivered to the Custodian each day and any excess collateral is returned to the borrower on the next business day. In the event the borrower fails to return the loaned securities when due, the Portfolio may take the collateral to replace the securities. If the value of the collateral is less than the purchase cost of replacement securities, the Custodian shall be responsible for any shortfall, but only to the extent that the shortfall is not due to any diminution in collateral value, as defined in the securities lending agreement. The Portfolio is required to maintain the collateral in a segregated account and determine its value each day until the loaned securities are returned. Cash collateral may be invested as determined by the Portfolio. Collateral is returned to the borrower upon settlement of the loan. There were no securities loaned as of December 31, 2023.

NOTES TO FINANCIAL STATEMENTS (Continued)

(f) Dividends to Shareholders: Dividends and distributions payable to shareholders are recorded by the Portfolio on the ex-dividend date. The Portfolio declares and pays dividends from net investment income, if available, annually. Dividends from net realized gains, offset by any loss carryforward, are declared and paid annually.

The characterization of distributions to shareholders for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Portfolio’s distributions may be shown in the accompanying financial statements as either from, or in excess of, net investment income, net realized gain on investment transactions, or return of capital, depending on the type of book/tax differences that may exist. Capital accounts within the financial statements are adjusted for permanent book/ tax differences. Reclassifications result primarily from the differences in tax treatment of net operating losses. The reclassifications are done annually at year-end and have no impact on the net asset value of the Portfolio and are designed to present the Portfolio’s capital accounts on a tax basis.

(g) Federal Income Taxes: It is the Portfolio’s policy to comply with the requirements of the Internal Revenue Code Subchapter M applicable to regulated investment companies and to distribute all of its taxable income to its shareholders. Provided that the Portfolio maintains such compliance, no federal income tax provision is required.

FASB Accounting Standards Codification 740 – Income Taxes (“ASC 740”) requires the Portfolio to measure and recognize in its financial statements the benefit of a tax position taken (or expected to be taken) on an income tax return if such position will more likely than not be sustained upon examination based on the technical merits of the position. No tax years are currently under investigation. The Portfolio files income tax returns in the U.S. Federal jurisdiction, as well as the New York State and New York City jurisdictions. The statute of limitations on the Portfolio’s tax returns remains open for the tax years 2019-2022. Management does not believe there are any uncertain tax positions that require recognition of a tax liability.

(h) Allocation Methods: The Fund accounts separately for the assets, liabilities and operations of the Portfolio. Expenses directly attributable to the Portfolio are charged to the Portfolio’s operations; expenses which are applicable to all Portfolios are allocated among them based on net assets.

^(a) Tier 1 rate is paid on assets up to $1 billion and Tier 2 rate is paid on assets in excess of $1 billion.

^(b) Alger Management has agreed to waive fees owed to it by, or to reimburse expenses of, the Portfolio in an amount corresponding to the management fee borne by the Portfolio as an investor in any underlying Alger Management-sponsored fund. This agreement will remain in effect for the life of any investment by the Portfolio in any Alger Management-sponsored fund. For the year ended December 31, 2023, the Portfolio waived $30,812 of such advisory fees. The “Actual Rate” shown above includes the impact of such waiver.

As of December 31, 2023, the components of accumulated gains (losses) on a tax basis were as follows:

During the year ended December 31, 2023, the Portfolio, for federal income tax purposes, had capital loss carryforwards of $45,787,551. This amount will not be subject to expiration under the Regulated Investment Company Modernization Act of 2010, and this amount may be applied against future net realized gains until its utilization.

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is determined annually and is attributable primarily to the tax deferral of losses on wash sales.

The Portfolio accrues tax on unrealized gains in foreign jurisdictions that impose a foreign capital tax. For the year ended December 31, 2023, there were no accrued taxes on foreign capital gains.

Permanent differences, primarily from net operating losses resulted in the following reclassifications among the Portfolio’s components of net assets at December 31, 2023:

* Prosetta Biosciences, Inc., Series D shares are classified as a Level 3 investment and are fair valued at zero as of December 31, 2023.

The significant unobservable inputs used in the fair value measurement of the Portfolio’s securities are revenue and EBITDA multiples, discount rates, and the probability of success of certain outcomes. Significant increases and decreases in these inputs in isolation and interrelationships between these inputs would have resulted in significantly higher or lower fair value measurements than those noted in the table above. Generally, all other things being equal, increases in revenue and EBITDA multiples, decreases in discount rates, and increases in the probability of success result in higher fair value measurements, whereas decreases in revenues and EBITDA multiples, increases in discount rates, and decreases in the probability of success result in lower fair value measurements. For the year ended December 31, 2023, there were no changes in valuation methodology on Level 3 investments.

Certain of the Portfolio’s assets and liabilities are held at carrying amount or face value, which approximates fair value for financial reporting purposes. As of December 31, 2023, such assets were categorized within the ASC 820 disclosure hierarchy as follows:

NOTE 9 — Principal Risks:

Investing in the stock market involves risks, including the potential loss of principal. Your investment in Portfolio shares represents an indirect investment in the securities owned by the Portfolio. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Portfolio shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Portfolio dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases and similar public health threats, recessions, or other events could have a significant impact on investments. Growth stocks may be more volatile than other stocks as their prices tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political, and economic developments. A significant portion of assets may be invested in securities of companies in related sectors, and may be similarly affected by economic, political, or market events and conditions and may be more vulnerable to unfavorable sector developments. Investing in companies of medium capitalizations involves the risk that such issuers may have limited product lines or financial resources, lack management depth, or have limited liquidity. Foreign securities involve special risks including currency fluctuations, inefficient trading, political and economic instability, and increased volatility. Active trading may increase transaction costs, brokerage commissions, and taxes, which can lower the return on investment. At times, the Portfolio may hold a large cash position, which may underperform relative to equity securities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders of Alger Mid Cap Growth Portfolio and the Board of Trustees of The Alger Portfolios:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Alger Mid Cap Growth Portfolio, (the “Fund”) one of the portfolios constituting The Alger Portfolios, as of December 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2023, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2023, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

ADDITIONAL INFORMATION (Unaudited)

Shareholder Expense Example

As a shareholder of the Portfolio, you incur two types of costs: transaction costs, if applicable; and ongoing costs, including management fees, distribution (12b-1) fees, if applicable, and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds.

The example below is based on an investment of $1,000 invested at the beginning of the six-month period starting July 1, 2023 and ending December 31, 2023 and held for the entire period.

Actual Expenses

The first line for each class of shares in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six Months Ended December 31, 2023” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each class of shares in the table below provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio for each class of the Portfolio’s shares and an assumed rate of return of 5% per year before expenses, which is not the Portfolio’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Portfolio and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs or deduction of insurance charges against assets or annuities. Therefore, the second line under each class of shares in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Board Approval of Investment Advisory Agreement

At a meeting held on September 19, 2023 (the “Meeting”), the Board of Trustees (the “Board”) of The Alger Portfolios (the “Trust”), including a majority of the trustees who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Trust (the “Independent Trustees”), reviewed and approved the continuation of the investment advisory agreement between Fred Alger Management, LLC (“Fred Alger Management” or the “Manager”) and the Trust, on behalf of the Fund (the “Management Agreement”), for an additional one-year period.

In considering the continuation of the Management Agreement, the Board reviewed and considered information provided by the Manager and its representatives at the Meeting and throughout the year at meetings of the Board and its committees. The Board also reviewed and considered information the Manager provided in response to a request for information Independent Trustee counsel submitted to the Manager on behalf of the Independent Trustees in connection with the Board’s annual contract consideration, as well as information provided in response to a supplemental request from Independent Trustee counsel on behalf of the Independent Trustees. The materials for the Meeting included a presentation and analysis of the Fund and the Manager by FUSE Research Network LLC (“FUSE”), an independent consulting firm. The Board also received a presentation from FUSE representatives at the Meeting and, among other things, received a description of the methodology FUSE used to select the mutual funds included in the Fund’s Peer Universe and Peer Group (as described below).

The Independent Trustees also received advice from, and met separately with, their Independent Trustee counsel in considering whether to approve the continuation of the Management Agreement. The Independent Trustees also received a memorandum from Independent Trustee counsel discussing the legal standards and their duties in considering the continuation of the Management Agreement, and counsel reviewed those standards with the Independent Trustees during their separate meeting. The Independent Trustees also met separately with senior management of the Manager, during which time the Independent Trustees discussed various matters related to proposed continuation of the Management Agreement.

The Board reviewed the materials provided and considered all of the factors it deemed relevant in approving the continuance of the Management Agreement, including, but not limited to: (i) the nature, extent and quality of the services provided by the Manager; (ii) the short- and long-term investment performance of the Fund; (iii) the costs of the services the Manager provided and profits it realized; (iv) the extent to which economies of scale are realized as the Fund grows; and (v) whether fee levels reflect these economies of scale for the benefit of Fund shareholders. The Board did not identify any one factor as dispositive, and each Board member may have attributed different weights to the factors considered.

In the discussions that follow, reference is made to the “median” in the Peer Group and Peer Universe categories. With respect to performance, below median performance represents performance that is worse relative to the median, and above median performance represents performance that is better relative to the median of the funds in the relevant Performance Universe. With respect to expenses, below median fees or expenses represent fees or expenses that are lower relative to the median, and above median fees or expenses represent fees or expenses that are higher relative to the median of the funds in the relevant Expense Group (as described below). FUSE information is calculated on a share class basis.

-38-

THE ALGER PORTFOLIOS | Alger Mid Cap Growth Portfolio
ADDITIONAL INFORMATION (Unaudited) (Continued)

In particular, in approving the continuance of the Management Agreement, the Board considered the following factors:

Nature, Extent and Quality of Services

The Board reviewed and considered information regarding the nature, extent and quality of investment management services provided by the Manager to the Fund. This information included, among other things, the qualifications, background and experience of the professional personnel who perform services for the Fund; the structure of investment professional compensation; oversight of third-party service providers; short- and long-term investment performance, fee and expense information; fees and payments to intermediaries for fund administration, transfer agency and shareholder services; legal and compliance matters; risk controls; pricing and other services provided by the Manager; and the range of advisory fees the Manager charged to other funds and accounts under its management, including the Manager’s explanation of differences among such funds and accounts and the Fund, where relevant. The Board noted that it received information at regular meetings throughout the year regarding the services rendered by the Manager concerning the management of the Fund’s affairs, including certain portfolio manager presentations, and the Manager’s role in coordinating and overseeing providers of other services to the Fund. The Board also noted the work undertaken by the Manager with respect to implementing new regulatory requirements applicable to the Fund.

The Board noted Fred Alger Management’s history and expertise in the “growth” style of investment management, as well as Fred Alger Management’s consistency in applying its “growth” style investment philosophy and process. The Board noted the length of time the Manager had provided services as an investment adviser to the Fund and also noted FUSE’s analysis that the long-term performance record of certain series in the Alger Family of Funds supports Fred Alger Management’s view on its overall investment capabilities.

The Board also reviewed and considered the benefits provided to Fund shareholders of investing in a Fund that is part of the Alger Family of Funds. The Board noted the continuing strong financial position of the Manager and its commitment to the fund business.

Following consideration of such information, the Trustees determined that they remain satisfied with the nature, extent and quality of services provided by the Manager to the Fund under the Management Agreement.

Fund Performance

The Board reviewed and considered the performance results of the Fund over various time periods. The Board considered the performance returns for the Fund in comparison to the performance returns of a universe of mutual funds deemed comparable to the Fund based on various investment, operational, and pricing characteristics (“Peer Universe”), and a group of mutual funds from within such Peer Universe deemed comparable to the Fund based primarily on investment strategy similarity (“Peer Group”), each as selected by FUSE, as well as to the Fund’s benchmark index. The Board noted that long-term performance could be impacted by one period of significant outperformance or underperformance.

-39-

THE ALGER PORTFOLIOS | Alger Mid Cap Growth Portfolio
ADDITIONAL INFORMATION (Unaudited) (Continued)

The Board also reviewed and considered Fund performance reports provided by management and discussions that occurred with investment personnel and senior management at Board meetings throughout the year. The Board further noted that representatives of the Manager review with the Trustees the recent and longer-term performance of the Fund, including contributors to and detractors from Fund performance at every quarterly meeting of the Board throughout the year.

In considering the Fund’s performance generally, the Board observed the Manager’s consistency in implementing its growth style investment process and philosophy for the Fund and considered how a strategy’s “growthiness” as compared to peers can impact relative performance results, even among comparisons that either FUSE or the Manager already have identified as having growth characteristics. In this regard, the Board considered FUSE’s commentary regarding the Fund’s growth investment style as compared to a universe of peers comprised of actively managed funds within the Fund’s Morningstar category and as compared to the Fund’s benchmark index, as measured by Morningstar’s Raw Value-Growth score.

The Trustees concluded that the Fund’s performance was acceptable, including particularly in the context of management’s plans to address underperformance where applicable. The Board noted that the Fund’s annualized total return for the one-, three-, five- and ten-year periods underperformed the median of its Peer Group. The Board also noted that the Fund’s annualized total return for the one- and ten-year periods was in the third quartile of its Peer Universe, and for the three- and five-year periods was in the fourth quartile of its Peer Universe. The Board considered FUSE’s commentary that the Fund is among the “growthiest” funds in its Peer Universe and the correlation to excess performance for mid cap growth funds with a lower growth style factor.

Comparative Fees and Expenses

The Board reviewed and considered the contractual management fee (the “Contractual Management Fee”) payable by the Fund to Fred Alger Management in light of the nature, extent and quality of the services provided by the Manager pursuant to the Management Agreement. The Board also considered the actual fee rate (after taking any waivers and reimbursements into account, if any) payable by the Fund (the “Actual Management Fee”). Additionally, the Board received and considered information comparing the Fund’s Contractual Management Fee, Actual Management Fee and overall expenses, including administrative fees payable to Fred Alger Management, with those of the funds in the Peer Group provided by FUSE. The Board reviewed the methodology used by FUSE in calculating expense information, including that for purposes of the comparisons below, the Contractual Management Fee used by FUSE for the Fund and peers includes the advisor fee and administrative fee, if a fund reports both.

-40-

THE ALGER PORTFOLIOS | Alger Mid Cap Growth Portfolio
ADDITIONAL INFORMATION (Unaudited) (Continued)

The Board discussed the factors that could contribute to the Fund’s Contractual Management Fee, Actual Management Fee or total expenses being above or below the median of the Fund’s Peer Group and concluded that the Contractual Management Fee charged to the Fund is reasonable in relation to the services rendered by Fred Alger Management and is the product of arm’s length negotiations.

The Board noted that the Contractual Management Fee and total expenses for the Fund were above the median and in the third quartile of its Peer Group.

In connection with its consideration of the Fund’s fees payable under the Management Agreement, the Board also received information on the range of fees charged by the Manager for funds and accounts of a similar investment strategy to the Fund that are under its management. The Board noted management’s explanation that comparisons with such accounts may be of limited relevance given the different structures and regulatory requirements of mutual funds, such as the Fund, versus those accounts and the differences in the levels of services required by the Fund as compared to those accounts.

Profitability

The Board reviewed and considered information regarding the profits realized by Fred Alger Management in connection with the operation of the Fund. In this respect, the Board considered overall profitability, including in comparison to certain investment advisory peers, as well as the profits of Fred Alger Management in providing investment management and other services to the Fund during the year ended June 30, 2023. The Board also reviewed the profitability methodology and any changes thereto, noting that management maintains a consistent methodology year to year. The Board considered FUSE’s view that Fred Alger Management’s expense allocation policies align with accepted industry practices.

The Board noted that costs incurred in establishing and maintaining the infrastructure necessary for the mutual fund operations conducted by Fred Alger Management may not be fully reflected in the expenses allocated to the Fund in determining Fred Alger Management’s profitability.

The Board also considered the extent to which the Manager might derive ancillary benefits from Fund operations, including, for example, through soft dollar arrangements. Based upon its consideration of all these factors, the Trustees concluded that the level of profits realized by Fred Alger Management and its affiliates from providing services to the Fund was not excessive in view of the nature, extent and quality of services provided to the Fund.

Economies of Scale

The Board reviewed and considered the extent to which the Manager may realize economies of scale, if any, as the Fund grows larger and whether the Fund’s management fee structure reflects any economies of scale for the benefit of Fund shareholders. The Board noted the existence of a management fee breakpoint for the Fund, which operates to share economies of scale with the Fund’s shareholders by reducing the Fund’s effective management fees as the Fund grows in size. The Board considered the Manager’s view that the overall size of Fred Alger Management allows it to realize other economies of scale, such as with office space, purchases of technology, and other general business expenses.

-41-

THE ALGER PORTFOLIOS | Alger Mid Cap Growth Portfolio
ADDITIONAL INFORMATION (Unaudited) (Continued)

The Trustees concluded that for the Fund, to the extent economies of scale may be realized by Fred Alger Management, the benefits of such economies of scale would be shared with the Fund and its shareholders as the Fund grows, including through the management fee breakpoint in place for the Fund.

Conclusion

The Board’s consideration of the Contractual Management Fee for the Fund also had the benefit of a number of years of reviews of the Management Agreement, during which lengthy discussions took place between the Board and representatives of the Manager. Certain aspects of the arrangements may receive greater scrutiny in some years than in others, and the Board’s conclusions may be based, in part, on its consideration of the Fund’s arrangements in prior years.

Based on its review, consideration and evaluation of all factors it believed relevant, including the above-described factors and conclusions, the Board, including the Independent Trustees voting separately, unanimously approved the continuation of the Management Agreement for an additional one-year period.

Fund Holdings

The Board has adopted policies and procedures relating to disclosure of the Portfolio’s securities. These policies and procedures recognize that there may be legitimate business reasons for holdings to be disclosed and seek to balance those interests to protect the proprietary nature of the trading strategies and implementation thereof by the Portfolio.

Generally, the policies prohibit the release of information concerning portfolio holdings, which have not previously been made public, to individual investors, institutional investors, intermediaries that distribute the Portfolio’s shares and other parties which are not employed by the Investment Manager or its affiliates except when the legitimate business purposes for selective disclosure and other conditions (designed to protect the Portfolio) are acceptable.

The Portfolio files its complete schedule of portfolio holdings with the SEC semi-annually in shareholder reports on Form N-CSR and after the first and third fiscal quarters as an exhibit to its reports on Form N-PORT. The Portfolio’s Forms N-CSR and N-PORT are available online on the SEC’s website at www.sec.gov.

No compensation or other consideration is directly received for the non-public disclosure of portfolio holdings information.

In accordance with the foregoing, the Portfolio provides portfolio holdings information to third parties including financial intermediaries and service providers who need access to this information in the performance of their services and are subject to duties of confidentiality (1) imposed by law, including a duty not to trade on non-public information, and/or (2) pursuant to an agreement that confidential information is not to be disclosed or used (including trading on such information) other than as required by law. From time to time, the Fund will communicate with these third parties to confirm that they understand the Portfolio’s policies and procedures regarding such disclosure. These agreements must be approved by the Portfolio’s Chief Compliance Officer.

The Board periodically reviews a report disclosing the third parties to whom the Portfolio’s holdings information has been disclosed and the purpose for such disclosure, and it considers whether or not the release of information to such third parties is in the best interest of the Portfolio and its shareholders.

Liquidity Risk Management Program

In accordance with Rule 22e-4 under the 1940 Act (the “Liquidity Rule”), the Fund has adopted and implemented a liquidity risk management program (the “LRMP”), which is reasonably designed to assess and manage the Portfolio’s liquidity risk.

The Board met on December 12, 2023 (the “Meeting”) to review the LRMP. The Board previously appointed Alger Management as the program administrator for the LRMP and approved an agreement with ICE Data Services (“ICE”), a third party vendor that assists the Portfolio with liquidity classifications required by the Liquidity Rule. Alger Management also previously delegated oversight of the LRMP to the Liquidity Risk Committee (the “Committee”). At the Meeting, the Committee, on behalf of Alger Management, provided the Board with a report that addressed the operation of the LRMP and assessed its adequacy and effectiveness of implementation, and any material changes to the LRMP (the “Report”). The Report covered the period from December 1, 2022 through November 30, 2023 (the “Review Period”).

The Report stated that the Committee assessed the Portfolio’s liquidity risk by considering qualitative factors such as the Portfolio’s investment strategy, holdings, diversification of investments, redemption policies, cash flows, cash levels, shareholder concentration, and access to borrowings, among others, in conjunction with the quantitative classifications generated by ICE. In addition, in connection with the review of the Portfolio’s liquidity risks and the operation of the LRMP and the adequacy and effectiveness of its implementation, the Committee also evaluated the levels at which to set the reasonably anticipated trade size (“RATS”) and market price impact. The Report described the process for determining that the Portfolio primarily holds investments that are highly liquid. The Report noted that the Committee also performed stress tests on the Portfolio, concluded that the Portfolio remained primarily highly liquid. The Report stated that during the Reporting Period, based on updates to Alger Management’s Rule 144A Policy and Procedures, the reporting of Rule 144A securities was updated to reflect the factors used to determine whether such securities, which are deemed illiquid, are liquid and freely tradeable.
