(e) (1) Audit Committee Pre-ApprovalPolicies and Procedures

THE PGIM MUTUAL FUNDS

AUDIT COMMITTEE POLICY

on

Pre-Approvalof Services Provided by the Independent

Accountants

The Audit Committee of each PGIM Mutual Fund is charged with the responsibility to monitor the independence of the Fund's independent accountants. As part of this responsibility, the Audit Committee must pre-approvethe independent accounting firm's engagement to render audit and/or permissible non-auditservices, as required by law. In evaluating a proposed engagement of the independent accountants, the Audit Committee will assess the effect that the engagement might reasonably be expected to have on the accountant's independence. The Committee's evaluation will be based on:

Policy for Audit and Non-AuditServices Provided to the Funds

On an annual basis, the scope of audits for each Fund, audit fees and expenses, and audit-related and non-auditservices (and fees proposed in respect thereof) proposed to be performed by the Fund's independent accountants will be presented by the Treasurer and the independent accountants to the Audit Committee for review and, as appropriate, approval prior to the initiation of such services.

Such presentation shall be accompanied by confirmation by both the Treasurer and the independent accountants that the proposed non-auditservices will not adversely affect the independence of the independent accountants. Such proposed non-auditservices shall be described in sufficient detail to enable the Audit Committee to assess the appropriateness of such services and fees, and the compatibility of the provision of such services with the auditor's independence. The Committee shall receive periodic reports on the progress of the audit and other services which are approved by the Committee or by the Committee Chair pursuant to authority delegated in this Policy.

The categories of services enumerated under "Audit Services", "Audit-related Services", and "Tax Services" are intended to provide guidance to the Treasurer and the independent accountants as to those categories of services which the Committee believes are generally consistent with the independence of the independent accountants and which the Committee (or the Committee Chair) would expect upon the presentation of specific proposals to pre-approve.The enumerated categories are not intended as an exclusive list of audit, audit-related or tax services, which the Committee (or the Committee Chair) would consider for pre-approval.

Audit Services

The following categories of audit services are considered to be consistent with the role of the Fund's independent accountants:

Audit-related Services

The following categories of audit-related services are considered to be consistent with the role of the Fund's independent accountants:

Individual audit-related services that fall within one of these categories (except for fund merger support services) and are not presented to the Audit Committee as part of the annual pre-approvalprocess are subject to an authorized pre-approvalby the Audit Committee so long as the estimated fee for those services does not exceed $30,000. Any services provided under such pre-approvalwill be reported to the Audit Committee at its next regular meeting. Should the amount of such services exceed $30,000 any additional fees will be subject to pre-approvalby the Committee Chair (or any other Committee member on whom this responsibility has been delegated). Fees related to fund merger support services are subject to a separate authorized pre-approvalby the Audit Committee with fees determined on a per occurrence and merger complexity basis.

Tax Services

The following categories of tax services are considered to be consistent with the role of the Fund's independent accountants:

Individual tax services that fall within one of these categories and are not presented to the Audit Committee as part of the annual pre-approvalprocess are subject to an authorized pre-approvalby the Audit Committee so long as the estimated fee for those services does not exceed $30,000. Any services provided under such pre-approvalwill be reported to the Audit Committee at its next regular meeting. Should the amount of such services exceed $30,000 any additional fees will be subject to pre-approvalby the Committee Chair (or any other Committee member on whom this responsibility has been delegated).

Other Non-AuditServices

Certain non-auditservices that the independent accountants are legally permitted to render will be subject to pre-approvalby the Committee or by one or more Committee members to whom the Committee has delegated this authority and who will report to the full Committee any pre-approvaldecisions made pursuant to this Policy. Non-auditservices presented for pre-approvalpursuant to this paragraph will be accompanied by a confirmation from both the Treasurer and the independent accountants that the proposed services will not adversely affect the independence of the independent accountants.

Proscribed Services

The Fund's independent accountants will not render services in the following categories of non-auditservices:

Pre-approvalof Non-AuditServices Provided to Other Entities Within the PGIM Fund Complex

Certain non-auditservices provided to PGIM Investments LLC or any of its affiliates that also provide ongoing services to the PGIM Mutual Funds will be subject to pre-approvalby the Audit Committee. The only non-auditservices provided to these entities that will require pre-approvalare those related directly to the operations and financial reporting of the Funds. Individual projects that are not presented to the Audit Committee as part of the annual pre-approvalprocess will be subject to pre-approvalby the Committee Chair (or any other Committee member on whom this responsibility has been delegated) so long as the estimated fee for those services does not exceed $30,000. Services presented for pre-approvalpursuant to this paragraph will be accompanied by a confirmation from both the Treasurer and the independent accountants that the proposed services will not adversely affect the independence of the independent accountants.

Although the Audit Committee will not pre-approveall services provided to PGIM Investments LLC and its affiliates, the Committee will receive an annual report from the Fund's independent accounting firm showing the aggregate fees for all services provided to PGIM Investments and its affiliates.

NOTES TO FINANCIAL STATEMENTS

1. Organization

Prudential's Gibraltar Fund, Inc. (the "Fund") was originally incorporated in the State of Delaware on March 14, 1968 and was reincorporated in the State of Maryland effective May 1, 1997. It is registered as an open-end,management investment company under the Investment Company Act of 1940, as amended ("1940 Act") and is a diversified fund for purposes of the 1940 Act. The Fund was organized by The Prudential Insurance Company of America ("PICA") to serve as the investment medium for the variable contract accounts of The Prudential Financial Security Program. The Fund does not sell its shares to the public.

The investment objective of the Fund is growth of capital to the extent compatible with a concern for preservation of principal. Current income, if any, is incidental.

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.

The Fund adopted FASB Accounting Standards Update 2023-07,Segment Reporting (Topic 280)-Improvements to Reportable Segment Disclosures ("ASU 2023-07").Adoption of ASU 2023-07exclusively impacted financial statement disclosures only and did not affect the Fund's financial position or performance. The intent of ASU 2023-07is, through improved segment disclosures, to enable investors to better understand an entity's overall performance. The officers of the Fund, as listed in the Fund's Statement of Additional Information, act as the Fund's chief operating decision maker ("CODM"). The CODM has determined that the Fund has a single operating segment as the CODM monitors the operating results of the Fund as a whole and the Fund's long-term strategic asset allocation is pre-determinedin accordance with the terms of its respective prospectus, based on a defined investment strategy which is executed by the Fund's subadviser.

The CODM allocates resources and assesses performance based on the operating results of the Fund, which is consistent with the results presented in the Fund's Schedule of Investments, Statement of Changes in Net Assets and Financial Highlights.

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 Fund's Board of Directors (the "Board") has approved the Fund's valuation policies and procedures for security valuation and designated PGIM Investments LLC ("PGIM Investments", the "Investment Manager" or the "Manager") as the "Valuation Designee," as defined by Rule 2a-5(b)under the 1940 Act, to perform the fair value determination relating to all Fund investments. Pursuant to the Board's oversight, the Valuation Designee has established a Valuation Committee to perform the duties and responsibilities of the Valuation Designee under Rule 2a-5.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 estimated 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.

For the fiscal reporting year-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 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 ("ETFs") 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

B1

hierarchy. In the event that no sale or official closing price on a 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-endfunds (other than ETFs) 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 policies and procedures 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; and any available analyst media or other reports or information deemed reliable by the Valuation Designee 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.

Master Netting Arrangements: 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-offexists 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-offthe amount owed with the amount owed by the other party, the reporting party intends to set-offand the right of set-offis 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 the 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 open loans 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. Interest income, including amortization of premium and accretion of discount on debt securities, as required, is recorded on the accrual basis. Expenses are recorded on an accrual basis, which may require the use of certain estimates by management that may differ from actual expense amounts.

B2

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 substantially 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-incapital 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.

* 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 Fund has a management agreement with the Manager pursuant to which it has responsibility for all investment advisory services, including supervision of the subadviser's performance of such services, and for rendering administrative services.

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

The management fee paid to the Manager is accrued daily and payable monthly at an annual rate of 0.55% of average daily net assets of the Fund. All amounts paid or payable by the Fund to the Manager, under the agreement, are reflected in the Statement of Operations.

The Fund has a distribution agreement with Prudential Investment Management Services LLC ("PIMS"), which acts as the distributor of the shares of the Fund. No distribution or service fees are paid to PIMS as distributor of shares of the Fund.

The Fund has entered into brokerage commission recapture agreements with certain registered broker-dealers. Under the brokerage commission recapture program, a portion of the commission is returned to the Fund. Such amounts are included within realized gain (loss) on investment transactions presented in the Statement of Operations. For the reporting period ended December 31, 2025, brokerage commissions recaptured under these agreements was $1,457.

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

4. Other Transactions with Affiliates

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"). The Core Fund and the Money Market Fund are each a series 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-7procedures. Rule 17a-7is 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 year ended December 31, 2025, no Rule 17a-7transactions were entered into by the Fund.

5. Portfolio Securities

The aggregate cost of purchases and proceeds from sales of portfolio securities (excluding short-term investments and U.S. Government securities) for the year ended December 31, 2025, were as follows:

A summary of the cost of purchases and proceeds from sales of shares of affiliated investments for the year ended December 31, 2025, is presented as follows:

6. Distributions and Tax Information

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.In order to present total distributable earnings (loss) and paid-incapital in excess of par on the Statement of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to total distributable earnings (loss) and paid-incapital in excess of par for the Fund. The adjustments were due to net operating loss.

For the year ended December 31, 2025, the adjustments were as follows:

For the year ended December 31, 2025, the tax character of dividends paid as reflected in the Statement of Changes in Net Assets were as follows:

For the year ended December 31, 2024, the tax character of dividends paid as reflected in the Statement of Changes in Net Assets were as follows:

B4

For the year ended December 31, 2025, the Fund had the following amounts of accumulated undistributed earnings on a tax basis:

The United States federal income tax basis of the Fund's investments and the net unrealized appreciation (depreciation) as of December 31, 2025 were as follows:

The difference between GAAP and tax basis is primarily attributable to deferred losses on wash sales.

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 December 31, 2025 are subject to such review.

7. Borrowings

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-endas well as the prior SCA.

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 did not utilize the SCA during the year ended December 31, 2025.

8. Capital and Ownership

Pursuant to the Fund's Articles of Incorporation, the Fund is authorized to issue 75,000,000 shares, with a par value of $0.01 per share, and an aggregate par value of $750,000.

As of December 31, 2025, all shares of record of the Fund were owned by PICA on behalf of the owners of the three variable insurance products: Prudential's Investment Plan Account, Prudential's Annuity Plan Account and Prudential's Annuity Plan Account-2.

9. Risks of Investing in the Fund

The Fund's principal 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.

Equity Securities Risk: The value of a particular stock or equity-related security held by the Fund could fluctuate, perhaps greatly, in response to a number of factors, such as changes in the issuer's financial condition or the value of the equity markets or a sector of those markets. Such events may result in losses to the Fund. In addition, due to decreases in liquidity, the Fund may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price.

Exchange-Traded Fund (ETF) Risk: Exchange-Traded Funds (ETF) Risk. An investment in an ETF generally presents the same primary risks as an investment in a mutual fund that has the same investment objective, strategies, and policies. In addition, the market price of an ETF's shares may trade above or below its net asset value and there may not be an active trading market for an ETF's shares. The Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.

Expense Risk: The actual cost of investing in the Fund may be higher than the expenses shown in the "Annual Fund Operating Expenses" table above for a variety of reasons, including, for example, if the Fund's average net assets decrease.

Fixed Income Securities Risk: Investment in fixed income securities involves a variety of risks, including that: an issuer or guarantor of a security will be unable or unwilling to pay obligations when due; due to decreases in liquidity, the Fund may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price; and the Fund's investment may decrease in value when interest rates rise. Volatility in interest rates and in fixed income markets may increase the risk that the Fund's investment in fixed income securities will go down in value. In recent years, the US government began implementing increases to the federal funds interest rate and there may be further rate increases. To the extent rates increase substantially and/or rapidly, a fund with significant investment in fixed income investments may be subject to significant losses. Changes in interest rates may also affect the liquidity of the Fund's investments in fixed income securities.

Inflation and Deflation Risk: The Fund may be subject to inflation and deflation risk. Inflation risk is the risk that the value of assets or income from its investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund's holdings could decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund's holdings. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy (or expectations that such policies will change), and the Fund's investments may not keep pace with inflation, which may result in losses to Fund investors. Fiscal, economic, monetary or other governmental policies or measures have in the past, and may in the future, cause or exacerbate risks associated with interest rates, including changes in interest rates. Generally, securities issued in emerging markets are subject to a greater risk of inflationary or deflationary forces, and more developed markets are better able to use monetary policy to normalize markets.

Investment Style Risk: Securities held by the Fund as a result of a particular investment style, such as growth or value, tend to perform differently (i.e., better or worse than other segments of, or the overall, stock market) depending on market and economic conditions and investor sentiment. At times when the investment style is out of favor, the Fund may underperform other funds that invest in similar asset classes but use different investment styles.

Large Company Risk: Large-capitalization stocks as a group could fall out of favor with the market, causing the Fund to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies. Investments in securities of certain issuers with the largest market capitalizations can result in greater investment exposure to a limited number of issuers and sectors, primarily the technology sector, which can result in greater losses in the event of a market downturn or deteriorating fundamentals in those issuers or sectors.

Liquidity and Valuation Risk: The Fund may hold one or more securities for which there are no or few buyers and sellers or the securities are subject to limitations on transfer. The Fund may be unable to sell those portfolio holdings at the desired time or price and may have difficulty determining the value of such securities for the purpose of determining the Fund's net asset value. In such cases, investments owned by the Fund may be valued at fair value pursuant to policies and procedures adopted and implemented by the investment manager. No assurance can be given that the fair value prices accurately reflect the value of the security. The Fund is subject to a liquidity risk management program, which limits the ability of the Fund to invest in illiquid investments.

B6

Market and Management Risk: Markets in which the Fund invests may experience volatility and go down in value, and possibly sharply and unpredictably. Investment techniques, risk analyses, and investment strategies, which may include quantitative models or methods, used by a subadviser in making investment decisions for the Fund are subject to human error and may not produce the intended or desired results. While a Portfolio Manager or Subadviser(s) may make efforts to control the risks associated with market changes, and may attempt to identify changes as they occur, market environment changes can be sudden and extreme. The value of the Fund's investments may be negatively affected by the occurrence of domestic or global events, including war, terrorism, significant or unexpected failures, near-failures or credit downgrades of key institutions, unexpected changes in the prices of key commodities, government actions, environmental or natural disasters, sanctions, cybersecurity events, supply chain disruptions, political or civil instability, and public health emergencies, among others. Such events may reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and have a significant adverse impact on the economy. These events can adversely affect the liquidity and volatility of investments held by the Portfolio, and there is no guarantee that the investment objective of the Fund will be achieved. In periods of market volatility and/or declines, the Portfolio may experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices.

Mid-SizedCompany Risk: The shares of mid-sizedcompanies tend to trade less frequently than those of larger, more established companies, which can have an adverse effect on the pricing and volatility of these securities and on the Fund's ability to sell the securities.

Regulatory Risk: The Fund is subject to a variety of laws and regulations that govern its operations. The Fund is subject to regulation by the Securities and Exchange Commission (the SEC). Similarly, the businesses and other issuers of the securities and other instruments in which the Fund invests are also subject to considerable regulation. Changes in laws and regulations may materially impact the Fund, a security, business, sector, or market.

10. Recent Accounting Pronouncement and Regulatory Developments

During the reporting period, the Fund adopted Accounting Standards Update 2023-09,Income Taxes (Topic 740) -Improvements to Income Tax Disclosures ("ASU 2023-09").The amendments enhance income tax disclosures by requiring greater disclosure of income taxes paid by jurisdiction. The Fund did not pay a significant amount of foreign or U.S. federal, state or local income taxes and therefore did not include any additional disclosures in these financial statements.

11. Subsequent Event

The Fund's management evaluated subsequent events through the date of issuance of the financial statements. There have been no subsequent events that occurred during such period that would require disclosure in, or would be required to be recognized in, the financial statements as of December 31, 2025.

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Prudential's Gibraltar Fund, Inc.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements 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 of these financial statements 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 are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, 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.

Our procedures included confirmation of securities owned as of December 31, 2025 by correspondence with the custodian, transfer agent and broker.
