Letter from the President

Dear Shareholder: We hope you find the semiannual report for PGIM Jennison Mid-Cap Growth Fund informative and useful. The report covers performance for the six-month period ended February 28, 2022. Regarding your investments with PGIM, we believe it is important to maintain a diversified portfolio of funds consistent with your tolerance for risk, time horizon, and financial goals.

Your financial advisor can help you create a diversified investment plan that may include funds covering all the basic asset classes and that reflects your personal investor profile and risk tolerance. However, diversification and asset allocation strategies do not assure a profit or protect against loss in declining markets. At PGIM Investments, we consider it a great privilege and responsibility to help investors participate in opportunities across global markets while meeting their toughest investment challenges. PGIM is a top-10 global investment manager with more than $1 trillion in assets under management. This investment expertise allows us to deliver actively managed funds and strategies to meet the needs of investors around the globe. Thank you for choosing our family of funds. Sincerely, Stuart S. Parker, President PGIM Jennison Mid-Cap Growth Fund April 15, 2022

The returns in the tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or following the redemption of Fund shares. The average annual total returns take into account applicable sales charges, which are described for each share class in the table below.

Benchmark Definitions

Russell Midcap Growth Index—The Russell Midcap Growth Index is an unmanaged index, which is a market value-weighted index that measures the performance of those Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values.

Russell Midcap Index—The Russell Midcap Index is an unmanaged index that measures the performance of the 800 smallest companies in the Russell 1000 Index, which represent approximately 25% of the total market capitalization of the Russell 1000 Index.

Investors cannot invest directly in an index. The returns for the Indexes would be lower if they included the effects of sales charges, operating expenses of a mutual fund, or taxes that may be paid by an investor.

Fees and Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemptions, as applicable, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses, as applicable. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 held through the six-month period ended February 28, 2022. The example is for illustrative purposes only; you should consult the Prospectus for information on initial and subsequent minimum investment requirements.

Actual Expenses

The first line for each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information on 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 ÷$1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each share class in the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

The Fund’s transfer agent may charge additional fees to holders of certain accounts that are not included in the expenses shown in the table on the following page. These fees apply to individual retirement accounts (IRAs) and Section 403(b) accounts. As of the close of the six-month period covered by the table, IRA fees included an annual maintenance fee of $15 per account (subject to a maximum annual maintenance fee of $25 for all accounts held by the same shareholder). Section 403(b) accounts are charged an annual $25 fiduciary maintenance fee. Some of the fees may vary in amount, or may be waived, based on your total account balance or the number of PGIM funds, including the Fund, that you own. You should consider the additional fees that were charged to your Fund account over the six-month period when you estimate the total ongoing expenses paid over the period and the impact of these fees on your ending account value, as these additional expenses are not reflected in the information

PGIM Jennison Mid-Cap Growth Fund 7

Fees and Expenses (continued)

provided in the expense table. Additional fees have the effect of reducing investment returns.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads). Therefore, the second line for each share class 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.

*Fund expenses (net of fee waivers or subsidies, if any) for each share class are equal to the annualized expense ratio for each share class (provided in the table), multiplied by the average account value over the period, multiplied by the 181 days in the six-month period ended February 28, 2022, and divided by the 365 days in the Fund’s fiscal year ending August 31, 2022 (to reflect the six-month period). Expenses presented in the table include the expenses of any underlying portfolios in which the Fund may invest.

Notes to Financial Statements (unaudited)

1.    Organization

Prudential Jennison Mid-Cap Growth Fund, Inc. (the “Registered Investment Company” or “RIC”) is registered under the Investment Company Act of 1940, as amended (“1940 Act”), as an open-end management investment company. The RIC is organized as a Maryland Corporation and PGIM Jennison Mid-Cap Growth Fund (the “Fund”) is the sole series of the RIC. The Fund is classified as a diversified fund for purposes of the 1940 Act.

The investment objective of the Fund is to achieve long-term capital appreciation.

2.    Accounting Policies

The Fund follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 946 Financial Services — Investment Companies. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The policies conform to U.S. generally accepted accounting principles (“GAAP”). The Fund consistently follows such policies in the preparation of its financial statements.

Securities Valuation: The Fund holds securities and other assets and liabilities that are fair valued as of the close of each day (generally, 4:00 PM Eastern time) the New York Stock Exchange (“NYSE”) is open for trading. As described in further detail below, the Fund’s investments are valued daily based on a number of factors, including the type of investment and whether market quotations are readily available. The RIC’s Board of Directors (the “Board”) has adopted valuation procedures for security valuation under which fair valuation responsibilities have been delegated to PGIM Investments LLC (“PGIM Investments” or the “Manager”). Pursuant to the Board’s delegation, the Manager has established a Valuation Committee responsible for supervising the fair valuation of portfolio securities and other assets and liabilities. The valuation procedures permit the Fund to utilize independent pricing vendor services, quotations from market makers, and alternative valuation methods when market quotations are either not readily available or not deemed representative of fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. A record of the Valuation Committee’s actions is subject to the Board’s review at its first quarterly meeting following the quarter in which such actions take place.

For the fiscal reporting period-end, securities and other assets and liabilities were fair valued at the close of the last U.S. business day. Trading in certain foreign securities may occur when the NYSE is closed (including weekends and holidays). Because such foreign securities trade in markets that are open on weekends and U.S. holidays, the values of some

PGIM Jennison Mid-Cap Growth Fund 27

Notes to Financial Statements (unaudited) (continued)

of the Fund’s foreign investments may change on days when investors cannot purchase or redeem Fund shares.

Various inputs determine how the Fund’s investments are valued, all of which are categorized according to the three broad levels (Level 1, 2, or 3) detailed in the Schedule of Investments and referred to herein as the “fair value hierarchy” in accordance with FASB ASC Topic 820 - Fair Value Measurement.

Common or preferred stocks, exchange-traded funds and derivative instruments, if applicable, that are traded on a national securities exchange are valued at the last sale price as of the close of trading on the applicable exchange where the security principally trades. Securities traded via NASDAQ are valued at the NASDAQ official closing price. To the extent these securities are valued at the last sale price or NASDAQ official closing price, they are classified as Level 1 in the fair value hierarchy. In the event that no sale or official closing price on valuation date exists, these securities are generally valued at the mean between the last reported bid and ask prices, or at the last bid price in the absence of an ask price. These securities are classified as Level 2 in the fair value hierarchy.

Investments in open-end funds (other than exchange-traded funds) are valued at their net asset values as of the close of the NYSE on the date of valuation. These securities are classified as Level 1 in the fair value hierarchy since they may be purchased or sold at their net asset values on the date of valuation.

Securities and other assets that cannot be priced according to the methods described above are valued based on pricing methodologies approved by the Board. In the event that unobservable inputs are used when determining such valuations, the securities will be classified as Level 3 in the fair value hierarchy. Altering one or more unobservable inputs may result in a significant change to a Level 3 security’s fair value measurement.

When determining the fair value of securities, some of the factors influencing the valuation include: the nature of any restrictions on disposition of the securities; assessment of the general liquidity of the securities; the issuer’s financial condition and the markets in which it does business; the cost of the investment; the size of the holding and the capitalization of the issuer; the prices of any recent transactions or bids/offers for such securities or any comparable securities; any available analyst media or other reports or information deemed reliable by the Manager regarding the issuer or the markets or industry in which it operates. Using fair value to price securities may result in a value that is different from a security’s most recent closing price and from the price used by other unaffiliated mutual funds to calculate their net asset values.

28

Master Netting Arrangements: The RIC, on behalf of the Fund, is subject to various Master Agreements, or netting arrangements, with select counterparties. These are agreements which a subadviser may have negotiated and entered into on behalf of all or a portion of the Fund. A master netting arrangement between the Fund and the counterparty permits the Fund to offset amounts payable by the Fund to the same counterparty against amounts to be received; and by the receipt of collateral from the counterparty by the Fund to cover the Fund’s exposure to the counterparty. However, there is no assurance that such mitigating factors are easily enforceable. In addition to master netting arrangements, the right to set-off exists when all the conditions are met such that each of the parties owes the other determinable amounts, the reporting party has the right to set-off the amount owed with the amount owed by the other party, the reporting party intends to set-off and the right of set-off is enforceable by law.

Securities Lending: The Fund lends its portfolio securities to banks and broker-dealers. The loans are secured by collateral at least equal to the market value of the securities loaned. Collateral pledged by each borrower is invested in an affiliated money market fund and is marked to market daily, based on the previous day’s market value, such that the value of the collateral exceeds the value of the loaned securities. In the event of significant appreciation in value of securities on loan on the last business day of the reporting period, the financial statements may reflect a collateral value that is less than the market value of the loaned securities. Such shortfall is remedied as described above. Loans are subject to termination at the option of the borrower or the Fund. Upon termination of the loan, the borrower will return to the Fund securities identical to the loaned securities. The remaining maturities of the securities lending transactions are considered overnight and continuous. Should the borrower of the securities fail financially, the Fund has the right to repurchase the securities in the open market using the collateral.

The Fund recognizes income, net of any rebate and securities lending agent fees, for lending its securities in the form of fees or interest on the investment of any cash received as collateral. The borrower receives all interest and dividends from the securities loaned and such payments are passed back to the lender in amounts equivalent thereto, which are reflected in interest income or unaffiliated dividend income based on the nature of the payment on the Statement of Operations. The Fund also continues to recognize any unrealized gain (loss) in the market price of the securities loaned and on the change in the value of the collateral invested that may occur during the term of the loan. In addition, realized gain (loss) is recognized on changes in the value of the collateral invested upon liquidation of the collateral. Net earnings from securities lending are disclosed in the Statement of Operations.

Securities Transactions and Net Investment Income: Securities transactions are recorded on the trade date. Realized gains (losses) from investment and currency transactions are calculated on the specific identification method. Dividend income is recorded on the ex-date, or for certain foreign securities, when the Fund becomes aware of such dividends. Expenses are recorded on an accrual basis, which may require the use of certain estimates by management that may differ from actual. Net investment income or loss (other than class

PGIM Jennison Mid-Cap Growth Fund 29

Notes to Financial Statements (unaudited) (continued)

specific expenses and waivers, which are allocated as noted below) and unrealized and realized gains (losses) are allocated daily to each class of shares based upon the relative proportion of adjusted net assets of each class at the beginning of the day. Class specific expenses and waivers, where applicable, are charged to the respective share classes. Such class specific expenses and waivers include distribution fees and distribution fee waivers, shareholder servicing fees, transfer agent’s fees and expenses, registration fees and fee waivers and/or expense reimbursements, as applicable.

Taxes: It is the Fund’s policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net investment income and capital gains, if any, to its shareholders. Therefore, no federal income tax provision is required. Withholding taxes on foreign dividends, interest and capital gains, if any, are recorded, net of reclaimable amounts, at the time the related income is earned.

Dividends and Distributions: Dividends and distributions to shareholders, which are determined in accordance with federal income tax regulations and which may differ from GAAP, are recorded on the ex-date. Permanent book/tax differences relating to income and gain (loss) are reclassified between total distributable earnings (loss) and paid-in capital in excess of par, as appropriate. The chart below sets forth the expected frequency of dividend and capital gains distributions to shareholders. Various factors may impact the frequency of dividend distributions to shareholders, including but not limited to adverse market conditions or portfolio holding-specific events.

Expected Distribution Schedule to Shareholders*	Frequency
Net Investment Income	Annually
Short-Term Capital Gains	Annually
Long-Term Capital Gains	Annually

* Under certain circumstances, the Fund may make more than one distribution of short-term and/or long-term capital gains during a fiscal year.

Estimates: The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

3.    Agreements

The RIC, on behalf of the Fund, has a management agreement with the Manager. Pursuant to this agreement, the Manager has responsibility for all investment advisory services and supervises the subadviser’s performance of such services.

30

The Manager has entered into a subadvisory agreement with Jennison Associates LLC (“Jennison” or “subadviser”). The Manager pays for the services of Jennison.

Fees payable under the management agreement are computed daily and paid monthly. For the reporting period ended February 28, 2022, the contractual and effective management fee rates were as follows:

Contractual Management Rate	Effective Management Fee, before any waivers and/or expense reimbursements
0.60% of average daily net assets up to $1 billion;		0.57%
0.55% of average daily net assets over $1 billion.

The Manager has contractually agreed, through December 31, 2022, to limit transfer agency, shareholder servicing, sub-transfer agency, and blue sky fees, as applicable. This contractual expense limitation excludes interest, brokerage, taxes (such as income and foreign withholding taxes, stamp duty and deferred tax expenses), acquired fund fees and expenses, extraordinary expenses, and certain other Fund expenses such as dividend and interest expense and broker charges on short sales.

Where applicable, the Manager agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives such expenses on any other share class. In addition, total annual operating expenses for Class R6 shares will not exceed total annual operating expenses for Class Z shares. Fees and/or expenses waived and/or reimbursed by the Manager may be recouped by the Manager within the same fiscal year during which such waiver and/or reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the recoupment for that fiscal year. The expense limitations attributable to each class are as follows:

Class	Expense Limitations
A		—	%
C		—
R		—
Z		—
R2		1.08
R4		0.83
R6		—

The RIC, on behalf of the Fund, has a distribution agreement with Prudential Investment Management Services LLC (“PIMS”), which acts as the distributor of the Class A, Class C, Class R, Class Z, Class R2, Class R4 and Class R6 shares of the Fund. The Fund compensates PIMS for distributing and servicing the Fund’s Class A, Class C, Class R and Class R2 shares, pursuant to the plans of distribution (the “Distribution Plans”), regardless of expenses actually incurred by PIMS.

Pursuant to the Distribution Plans, the Fund compensates PIMS for distribution related activities at an annual rate based on average daily net assets per class. PIMS has

PGIM Jennison Mid-Cap Growth Fund 31

Notes to Financial Statements (unaudited) (continued)

contractually agreed through December 31, 2022 to limit such expenses to 0.50% of the average daily net assets of the Class R shares.The distribution fees are accrued daily and payable monthly. The Fund’s annual distribution contractual rate and limit where applicable are as follows:

Class	Contractual Rate		Limit
A		0.30%		—	%
C		1.00		—
R		0.75		0.50
Z		N/A		N/A
R2		0.25		—
R4		N/A		N/A
R6		N/A		N/A

The Fund has adopted a Shareholder Services Plan with respect to Class R2 and Class R4 shares. Under the terms of the Shareholder Services Plan, Class R2 and Class R4 shares are authorized to pay to Prudential Mutual Fund Services LLC (“PMFS”), its affiliates or third-party service providers, as compensation for services rendered to the shareholders of such Class R2 or Class R4 shares, a shareholder service fee at an annual rate of up to 0.10% of the average daily net assets attributable to Class R2 and Class R4 shares. The shareholder service fee is accrued daily and paid monthly, as applicable.

For the reporting period ended February 28, 2022, PIMS received front-end sales charges (“FESL”) resulting from sales of certain class shares and contingent deferred sales charges (“CDSC”) imposed upon redemptions by certain shareholders. From these fees, PIMS paid such sales charges to broker-dealers, who in turn paid commissions to salespersons and incurred other distribution costs. The sales charges are as follows where applicable:

FESL by Class	Amount
A		$162,990
C		—

CDSC by Class	Amount
A		$223
C		419

PGIM Investments, PIMS and Jennison are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. (“Prudential”).

4.    Other Transactions with Affiliates

PMFS serves as the Fund’s transfer agent. Transfer agent’s fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates, where applicable.

32

The Fund may invest its overnight sweep cash in the PGIM Core Ultra Short Bond Fund (the “Core Fund”), and its securities lending cash collateral in the PGIM Institutional Money Market Fund (the “Money Market Fund”), each a fund of Prudential Investment Portfolios 2, registered under the 1940 Act and managed by PGIM Investments. PGIM Investments and/or its affiliates are paid fees or reimbursed for providing their services to the Core Fund and the Money Market Fund. In addition to the realized and unrealized gains on investments in the Core Fund and Money Market Fund, earnings from such investments are disclosed on the Statement of Operations as “Affiliated dividend income” and “Income from securities lending, net”, respectively.

The Fund may enter into certain securities purchase or sale transactions under Board approved Rule 17a-7 procedures. Rule 17a-7 is an exemptive rule under the 1940 Act, that subject to certain conditions, permits purchase and sale transactions among affiliated investment companies, or between an investment company and a person that is affiliated solely by reason of having a common (or affiliated) investment adviser, common directors/trustees, and/or common officers. For the reporting period ended February 28, 2022, no 17a-7 transactions were entered into by the Fund.

6.     Tax Information

The United States federal income tax basis of the Fund’s investments and the net unrealized appreciation as of February 28, 2022 were as follows:

Tax Basis	Gross Unrealized Appreciation	Gross Unrealized Depreciation	Net Unrealized Appreciation
$1,999,228,637	$706,262,180	$(131,270,588)	$574,991,592

The GAAP basis may differ from tax basis due to certain tax-related adjustments.

The Manager has analyzed the Fund’s tax positions taken on federal, state and local income tax returns for all open tax years and has concluded that no provision for income tax is required in the Fund’s financial statements for the current reporting period. Since tax authorities can examine previously filed tax returns, the Fund’s U.S. federal and state tax returns for each of the four fiscal years up to the most recent fiscal year ended August 31, 2021 are subject to such review.

7.    Capital and Ownership

The Fund offers Class A, Class C, Class R, Class Z, Class R2, Class R4 and Class R6 shares. Class A shares are sold with a maximum front-end sales charge of 5.50%. Investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are subject to a contingent deferred sales charge (“CDSC”) of 1%, although they are not subject to an initial sales charge. The Class A CDSC is waived for certain retirement and/or benefit plans. A special exchange privilege is also available for shareholders who qualified to purchase Class A shares at net asset value. Class C shares are sold with a CDSC of 1% on sales made within 12 months of purchase. Class C shares will automatically convert to Class A shares on a monthly basis approximately eight years (ten years prior to January 22, 2021) after purchase. Class R, Class Z, Class R2, Class R4 and Class R6 shares are not subject to any sales or redemption charges and are available exclusively for sale to a limited group of investors.

Under certain circumstances, an exchange may be made from specified share classes of the Fund to one or more other share classes of the Fund as presented in the table of transactions in shares of common stock, below.

(a)    On December 27, 2021, the Fund declared a 4 to 1 reverse stock split.

On December 27, 2021, the Fund’s Class C shares implemented a four-into-one reverse stock split the net effect of which was to decrease the number of the Fund’s outstanding shares and increase the net asset value per share by a proportionate amount. While the number of the Fund’s outstanding shares decreased, neither the Fund’s holdings nor the total value of shareholders’ investments in the Fund were affected. Immediately after the reverse stock split, each shareholder maintained the same percentage of the Fund’s net assets prior to the reverse stock split. Capital share activity referenced in the Statement of Changes in Net Assets and in Note 7, as well as per share data in the Financial Highlights

38

for Class C shares have been restated to reflect the reverse stock split.

8. Borrowings

The RIC, on behalf of the Fund, along with other affiliated registered investment companies (the “Participating Funds”), is a party to a Syndicated Credit Agreement (“SCA”) with a group of banks. The purpose of the SCA is to provide an alternative source of temporary funding for capital share redemptions. The table below provides details of the current SCA in effect at the reporting period-end as well as the prior SCA.

	Current SCA	Prior SCA
Term of Commitment	10/1/2021 – 9/29/2022	10/2/2020 – 9/30/2021
Total Commitment	$ 1,200,000,000	$ 1,200,000,000
Annualized Commitment Fee on the Unused Portion of the SCA	0.15%	0.15%
Annualized Interest Rate on Borrowings	1.20% plus the higher of (1) the effective federal funds rate, (2) the one-month LIBOR rate or (3) zero percent	1.30% plus the higher of (1) the effective federal funds rate, (2) the one-month LIBOR rate or (3) zero percent

Certain affiliated registered investment companies that are parties to the SCA include portfolios that are subject to a predetermined mathematical formula used to manage certain benefit guarantees offered under variable annuity contracts. The formula may result in large scale asset flows into and out of these portfolios. Consequently, these portfolios may be more likely to utilize the SCA for purposes of funding redemptions. It may be possible for those portfolios to fully exhaust the committed amount of the SCA, thereby requiring the Manager to allocate available funding per a Board-approved methodology designed to treat the Participating Funds in the SCA equitably.

The Fund utilized the SCA during the reporting period ended February 28, 2022. The average daily balance for the 3 days that the Fund had loans outstanding during the period was approximately $7,345,333, borrowed at a weighted average interest rate of 1.30%. The maximum loan outstanding amount during the period was $12,621,000. At February 28, 2022, the Fund had an outstanding loan balance of $104,000.

9. Risks of Investing in the Fund

The Fund’s risks include, but are not limited to, some or all of the risks discussed below. For further information on the Fund’s risks, please refer to the Fund’s Prospectus and Statement of Additional Information.

Economic and Market Events Risk: Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth or the functioning of the securities markets, may at times result in

PGIM Jennison Mid-Cap Growth Fund 39

Notes to Financial Statements (unaudited) (continued)

unusually high market volatility, which could negatively impact performance. Relatively reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.

Equity and Equity-Related Securities Risk: Equity and equity-related securities may be subject to changes in value, and their values may be more volatile than those of other asset classes. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Growth Style Risk: The Fund’s growth style may subject the Fund to above-average fluctuations as a result of seeking higher than average capital growth. Growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Growth company stocks also typically lack the dividend yield that can lessen price declines in market downturns. Since the Fund follows a growth investment style, there is the risk that the growth investment style may be out of favor for a period of time. At times when the style is out of favor, the Fund may underperform the market in general, its benchmark and other mutual funds.

Increase in Expenses Risk: Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table in the Fund’s prospectus for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. Active and frequent trading of Fund securities can increase expenses.

Large Shareholder and Large Scale Redemption Risk: Certain individuals, accounts, funds (including funds affiliated with the Manager) or institutions, including the Manager and its affiliates, may from time to time own or control a substantial amount of the Fund’s shares. There is no requirement that these entities maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy. The Fund’s ability to pursue its investment objective after one or more large scale redemptions may be impaired and, as a result, the Fund may invest a larger portion of its assets in cash or cash equivalents.

40

Management Risk: The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

Market Disruption and Geopolitical Risks: Market disruption can be caused by economic, financial or political events and factors, including but not limited to, international wars or conflicts (including Russia’s military invasion of Ukraine), geopolitical developments (including trading and tariff arrangements, sanctions and cybersecurity attacks), instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health epidemics (including the outbreak of COVID-19 globally).

The extent and duration of such events and resulting market disruptions cannot be predicted, but could be substantial and could magnify the impact of other risks to the Fund. These and other similar events could adversely affect the U.S. and foreign financial markets and lead to increased market volatility, reduced liquidity in the securities markets, significant negative impacts on issuers and the markets for certain securities and commodities and/or government intervention. They may also cause short- or long-term economic uncertainties in the United States and worldwide. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively impacted. Further, due to closures of certain markets and restrictions on trading certain securities, the value of certain securities held by the Fund could be significantly impacted, which could lead to such securities being valued at zero.

COVID-19 and the related governmental and public responses have had and may continue to have an impact on the Fund’s investments and net asset value and have led and may continue to lead to increased market volatility and the potential for illiquidity in certain classes of securities and sectors of the market. They have also had and may continue to result in periods of business disruption, business closures, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the issuers in which the Fund invests. The occurrence, reoccurrence and pendency of public health epidemics could adversely affect the economies and financial markets either in specific countries or worldwide.

Market Risk: Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.

Medium Capitalization (Mid-Cap) Company Risk: The Fund’s investments in mid-cap companies carry more risk than investments in larger capitalized companies. Investments in mid-cap companies carry additional risks because earnings of these companies tend to be less predictable; they often have limited product lines, markets, distribution channels or financial resources; and the management of such companies may be dependent on one or a few key people. The market movements of these companies’ securities may be more

PGIM Jennison Mid-Cap Growth Fund 41

Notes to Financial Statements (unaudited) (continued)

abrupt or erratic than the market movements of securities of larger, more established companies or the stock market in general. Historically, mid-cap companies have sometimes gone through extended periods when they did not perform as well as larger companies. Mid-cap companies generally are comparatively less liquid than larger companies, which may make such investments more difficult to sell at the time and price that the Fund would like. Also, the stocks of mid-cap companies may fall out of favor relative to those of small- or large-capitalization companies, causing the Fund to underperform other equity funds that focus on small or large-capitalization companies.

10. Recent Regulatory Developments

On December 3, 2020, the SEC announced that it voted to adopt a new rule that establishes an updated regulatory framework for fund valuation practices (the “Rule”). The Rule, in part, provides (i) a framework for determining fair value in good faith and (ii) provides for a fund Board’s assignment of its responsibility for the execution of valuation-related activities to a fund’s investment adviser. Further, the SEC is rescinding previously issued guidance on related issues. The Rule took effect on March 8, 2021, with a compliance date of September 8, 2022. Management is currently evaluating the Rule and its impact to the Fund.
