@ Security exempt from registration under Rule 144A of the Securities Act of 1933, as amended. At June 30, 2026, the aggregate value of Rule 144A securities was $259,034,509, which represents 5.3% of the Fund’s net assets.
* Non-income producing security.
†† At June 30, 2026, all or a portion of this security is pledged as collateral for OTC derivatives.
(1) The value of this security was determined using significant unobservable inputs and is reported as a Level 3 security in the Valuation Hierarchy table located at the end of the Schedule of Investments.
# Restricted Security. These investments are in securities not registered under the Securities Act of 1933, as amended, and have certain restrictions on resale which may limit their liquidity. At June 30, 2026, the aggregate value of restricted securities was $48,148,518 which represented 1.0% of the Fund's net assets. The Fund has various registration rights (exercisable under a variety of circumstances) with respect to these securities.

Variable rate security. The rate disclosed is the rate in effect on the report date. The information in parenthesis represents the benchmark and reference rate for each relevant security and the rate floats based upon the reference rate and spread. The security may be further subject to interest rate floors and caps. For loan agreements, the rate shown may represent a weighted average interest rate. Certain variable rate securities are not based on a published reference rate and spread, but are determined by the issuer or agent and are based on current market conditions, or, for mortgage-backed securities, are impacted by the individual mortgages which are paying off over time. These securities do not indicate a reference rate and spread in their descriptions.
Loan Agreements in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the Prime Rate offered by one or more major U.S. banks, (ii) the lending rate offered by one or more European banks such as the Secured Overnight Financing Rate (“SOFR”) or (iii) the Certificate of Deposit rate. Rate shown represents the actual rate at June 30, 2026. Loan Agreements, while exempt from registration under the Security Act of 1933, as amended (the “1933 Act”), contain certain restrictions on resale and cannot be sold publicly. Floating rate Loan Agreements often require repayments from excess cash flow or permit the borrower to repay at its election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturity shown.
× This loan will settle after June 30, 2026, at which time the interest rate, based on the SOFR and the agreed upon spread on trade date, will be reflected.

(1) Other financial instruments are derivative instruments not reflected in the value of total investments in securities in the Schedule of Investments such as future contracts and forward foreign currency contracts which are valued at the unrealized appreciation (depreciation) on the instrument.
^ A reconciliation of Level 3 instruments is presented when the Fund has a significant amount of Level 3 investments at the beginning and/or end of the period in relation to the net assets. Management has concluded that Level 3 investments are not material in relation to net assets.
It is the Fund's practice to recognize transfers into and transfers out of Level 3 fair value hierarchy as of the beginning of period. The Fund did not have any transfers into and transfers out of Level 3 fair value hierarchy during the reporting period.

Total returns may reflect adjustments to conform with generally accepted accounting principles.
3 The ratio includes expenses waived/reimbursed net of amount recaptured and fees paid indirectly, where applicable; if expenses waived/ reimbursed net of amount recaptured and fees paid indirectly were excluded, the ratio would have been higher (lower), respectively, than the ratio shown.

2 Total investment return is based on the change in net asset value of a share during the period and assumes reinvestment of dividends and distributions at net asset value. Total returns do not reflect expenses associated with variable contracts such as administrative fees, account charges and surrender charges, which if reflected would reduce the total returns for all periods presented. Total returns may reflect adjustments to conform with generally accepted accounting principles.
3 The ratio includes expenses waived/reimbursed net of amount recaptured and fees paid indirectly, where applicable; if expenses waived/ reimbursed net of amount recaptured and fees paid indirectly were excluded, the ratio would have been higher (lower), respectively, than the ratio shown.

1 —  Organization
Penn Series Funds, Inc. (“Penn Series”) was incorporated in Maryland on April 22, 1982. Penn Series is registered under the Investment Company Act of 1940 ("1940 Act"), as amended, as an open-end, diversified management investment company. Penn Series is open only to purchasers of The Penn Mutual Life Insurance Company (“Penn Mutual”) and The Penn Insurance and Annuity Company insurance contracts and certain of Penn Mutual’s employee benefit plans.
Penn Series is presently offering shares in its Money Market, Limited Maturity Bond, Quality Bond, High Yield Bond, Flexibly Managed, Balanced, Large Growth Stock, Large Cap Growth, Large Core Growth, Large Cap Value, Large Core Value, Index 500, Mid Cap Growth, Mid Cap Value, Mid Core Value, SMID Cap Growth, SMID Cap Value, Small Cap Growth, Small Cap Value, Small Cap Index, Developed International Index, International Equity, Emerging Markets Equity, Real Estate Securities, Aggressive Allocation, Moderately Aggressive Allocation, Moderate Allocation, Moderately Conservative Allocation and Conservative Allocation Funds (each a “Fund” and collectively, the “Funds”). Penn Series also has the authority to issue shares in three additional funds, each of which would have their own investment objective and policies.
Fund of Funds (“FOFs”) – Each Penn Series FOF seeks to achieve its investment objective by investing in other Penn Series Funds (“Underlying Funds”) and uses asset allocation strategies to determine how much to invest in the Underlying Funds. Each of the following is a Penn Series FOFs: Balanced, Aggressive Allocation, Moderately Aggressive Allocation, Moderate Allocation, Moderately Conservative Allocation and Conservative Allocation Funds.
2 —  Significant Accounting Policies
The following significant accounting policies are followed by Penn Series in the preparation of its financial statements. The preparation of financial statements in accordance with the accounting principles generally accepted in the United States (“U.S. GAAP”) 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 and those differences could be material. The Funds are investment companies and follow the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 946.
Security Valuation:
In conjunction with and pursuant to the requirements of the 1940 Act and Rule 2a-5 (the “Rule”), the Board of the Penn Series Funds, Inc. (“Board”) has designated Penn Mutual Asset Management LLC (“PMAM” or the “Adviser”) as the Valuation Designee for the Funds. As Valuation Designee, PMAM has the responsibility for the fair value determination with respect to all Fund investments that do not have readily available market quotations or quotations that are no longer reliable.  PMAM has adopted policies and procedures related to the Rule, and established a Valuation Committee for Registered Investment Companies to oversee valuation practices including fair valuation of all Fund investments.
Money Market Fund — Investments in securities are valued using the amortized cost method as permitted by Rule 2a-7 under the Investment Company Act of 1940, which involves initially valuing investments at cost and thereafter assuming a constant amortization to maturity of any premium or discount. This method approximates market value.
Limited Maturity Bond, Quality Bond, High Yield Bond, Flexibly Managed, Large Growth Stock, Large Cap Growth, Large Core Growth, Large Cap Value, Large Core Value, Index 500, Mid Cap Growth, Mid Cap Value, Mid Core Value, SMID Cap Growth, SMID Cap Value, Small Cap Growth, Small Cap Value, Small Cap Index, Developed International Index, International Equity, Emerging Markets Equity, Real Estate Securities Funds — Portfolio securities listed on a securities exchange or an automated quotation system for which quotations are readily available, including securities traded over the counter, are valued at the last quoted sale price on the principal exchange or market on which they are traded on the valuation date or, if there is no such reported sale on the valuation date, at the most recent quoted bid price. Securities valued according to these valuation methods are categorized as Level 1 in the fair value hierarchy described below. Debt and fixed income securities are valued by recognized independent third-party valuation services, employing valuation methodologies that utilize actual market transactions, broker-dealer supplied valuations, and matrix pricing. Matrix pricing for corporate bonds, floating rate notes, municipal securities and

Notes to Financial Statements — June 30, 2026(Unaudited)

U.S. government and government agency obligations considers yield or price of bonds of comparable quality, coupon, maturity and type and, for asset backed securities, commercial mortgage securities and U.S. government agency mortgage securities, also considers prepayment speed assumptions and attributes and performance of the underlying collateral. Securities valued according to these valuation methods are generally categorized as Level 2 in the fair value hierarchy described below. To the extent that bid prices are provided by the pricing service, the Funds will use the bid price. Debt obligations with remaining maturities of sixty days or less may be valued at their amortized cost, which approximates market value. The prices for foreign securities are reported in local currency and converted to U.S. dollars using currency exchange rates as of the valuation date.
Options are valued at the last traded price on the market where such options are principally traded or, if there was no trade on such day, at the last bid quote. Futures contracts are valued at the last settlement price on the market where such futures contracts are principally traded. Although derivatives may be subject to netting provisions, as discussed further in Note 7, derivatives held are valued at their gross amounts.
Certain events may occur between the time that foreign markets close, on which securities held by the Fund principally trade, and the time at which the Fund’s NAV is calculated. These securities are valued at a fair value utilizing an independent third party valuation service in accordance with procedures adopted by the Fund’s Board of Directors. The methodology and procedures followed by the valuation service consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments such as ADRs, financial futures, ETFs, and certain indexes as well as prices for similar securities. Securities valued using such valuation service are classified as Level 2 of the fair value hierarchy as these adjustment factors are considered other observable inputs to the valuation. Values from the valuation service are applied in the event that there is a movement in the U.S. market that exceeds a specific threshold that has been established by the Valuation Committee. The Valuation Committee has also established a “confidence interval”, which is used to determine the level of historical correlation between the value of a specific foreign security and movements in the U.S. market before a particular security will be fair valued when the threshold is exceeded. In the event that the threshold established by the Valuation Committee is exceeded on a specific day, the Funds shall value the non-U.S. securities in their portfolios that exceed the applicable “confidence interval” based upon the adjusted prices provided by the fair valuation service.
The determination of a security’s fair value price often involves the consideration of a number of subjective factors, and is therefore subject to the unavoidable risk that the value assigned to a security may be higher or lower than the security’s value would be if a reliable market quotation for the security was readily available.
Balanced, Aggressive Allocation, Moderately Aggressive Allocation, Moderate Allocation, Moderately Conservative Allocation and Conservative Allocation Funds — The valuation of each Fund’s investment in its Underlying Funds is based on the net asset values of the Underlying Funds each business day.
Fair value measurements are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Funds’ investments. Inputs refer broadly to the assumptions that market participants would use in pricing an asset. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. These inputs are summarized into three broad levels as follows:
Level 1 — quoted prices in active markets for identical securities
Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)
Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)
Level 3 items at June 30, 2026 consist of equities in the High Yield Bond Fund, Flexibly Managed Fund, Large Growth Stock Fund and Small Cap Index Fund, respectively which were not publicly trading. The unobservable inputs used in valuing these securities include new rounds of financing, negotiated transactions of significant size between
159

Notes to Financial Statements — June 30, 2026(Unaudited)

other investors in the company, relevant market valuations of peer companies and strategic events affecting the company. Significant increases (decreases) in the valuation indicated by the new rounds of financing, valuations observed through negotiated transactions between other investors in the company or changes in the market valuation of relevant peer companies would result in directionally similar changes to the fair value. Fair value determinations are reviewed and updated on a regular basis and as information becomes available, including actual purchase and sale transactions of the issue. For certain loan agreements where observable inputs are limited, assumptions about market activity and risk are used and are categorized as Level 3 in the hierarchy.
Foreign Currency Translation The books and records of the Funds are maintained in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on the following basis: market value of investment securities, assets and liabilities at the current rate of exchange; purchases and sales of investment securities, income and expenses at the relevant rates of exchange prevailing on the respective dates of such transactions.
The Funds do not isolate the portion of realized and unrealized gains and losses on investments which is due to changes in the foreign exchange rate from that which is due to changes in market prices of all securities. Such fluctuations are included with net realized and unrealized gain or loss from investments.
Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of, among other factors, the level of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability.
Loan Agreements Certain Funds may invest in loan agreements, also known as bank loans, which represent an interest in amounts owed by a borrower to a syndication of lenders. Bank loans may involve multiple loans with the same borrower under a single credit agreement (each loan, a tranche), and each tranche may have different terms and associated risks. A bank or other financial institution typically acts as the agent and administers a bank loan in accordance with the associated credit agreement. Bank loans are generally noninvestment grade and often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Funds may buy and sell bank loans in the form of either loan assignments or loan participations. A loan assignment transfers all legal, beneficial, and economic rights to the buyer. Although loan assignments continue to be administered by the agent, the buyer acquires direct rights against the borrower. In many cases, a loan assignment requires the consent of both the borrower and the agent. In contrast, a loan participation generally entitles the buyer to receive the cash flows from principal, interest, and any fee payments that the seller is entitled to receive from the borrower; however, the seller continues to hold legal title to the loan. As a result, with loan participations, the buyer generally has no right to enforce compliance with terms of the credit agreement against the borrower, and the buyer is subject to the credit risk of both the borrower and the seller. Bank loans often have extended settlement periods, during which the Fund is subject to nonperformance by the counterparty.
Security Transactions, Investment Income and Expenses Security transactions are accounted for on the trade date. Dividend income is recorded on the ex-dividend date and interest income is accrued as earned. Discounts and premiums on debt and fixed income securities are accreted and amortized using the effective interest method. Premiums on callable debt securities are amortized to interest income to the earliest call date using the effective interest method. The cost of investment securities sold is determined by using the specific identification method for both financial reporting and income tax purposes. Expenses directly attributable to a Fund are directly charged. Expenses included in the accompanying financial statements reflect the expenses of each Fund and do not include any expenses associated with the Underlying Funds of the FOFs. Other expenses attributable to the Funds are allocated in accordance with methodologies, which are reviewed with the Board of Directors no less than annually.
Foreign dividends are recorded on the ex-dividend date or as soon after the ex-dividend date that the Funds are aware of such dividends, net of all tax withholdings, a portion of which may be reclaimable. Withholding taxes and reclaims on foreign dividends have been recorded in accordance with the Funds’ understanding of the applicable country’s tax rules and rates. The Funds file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. The Funds may record a reclaim receivable based on collectability, which includes factors such as the jurisdiction’s applicable laws, payment history and market convention. The "Statement of operations" includes tax reclaims recorded as well as professional and other fees, if any, associated with recovery of foreign withholding taxes. Income and capital gain distributions from any investment companies (Underlying Funds) in which the Funds invest are recorded on the ex-dividend date. The Funds declare and pay dividends from net investment

income and distributions from net realized gain on investments, if any, at least annually. The Funds may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.
Dividends to Shareholders Except for the Money Market Fund, all or a portion of each Fund’s undistributed net investment income and accumulated net realized gain on investment and foreign exchange transactions, if any, at June 30, 2026 were deemed distributed as consent dividends to each respective Fund’s shareholders in place of regular distributions. As consent dividends, shareholders of each Fund agree to treat their share of undistributed net investment income and accumulated net realized gain on investment and foreign exchange transactions, if any, at June 30, 2026, respectively, as dividend income and net capital gains for tax purposes. In the case of the Money Market Fund, dividends paid from undistributed net investment income and accumulated net realized gain on investments are declared daily and paid monthly.
Dividends from net investment income and distributions from net realized gains are determined in accordance with federal income tax regulations which may differ from net investment income and net realized capital gains recorded in accordance with accounting principles generally accepted in the United States. To the extent that these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification. Distributions from net realized gains may involve short-term capital gains, which are included as ordinary income for tax purposes.
The character of distributions received from Real Estate Investment Trusts (“REITs”) held by a Fund is generally comprised of net investment income, capital gains, and return of capital. It is the policy of the Funds to estimate the character of distributions received from the underlying REITs based on historical data provided by the REITs.
Foreign Capital Gains Taxes The International Equity Fund and Emerging Markets Equity Fund accrue capital gains tax on unrealized and realized gains for certain securities of issuers domiciled in India. For the six months ended June 30, 2026, the International Equity Fund and Emerging Markets Equity Fund had realized capital gains tax expense of $263 and $130,892, respectively, which is reflected in the Net realized gain (loss) on Investments line item in the Statement of Operations.
Segment ReportingAn operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by a public entity’s chief operating decision maker (the “CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Funds’ President, Treasurer and Chief Compliance Officer act together as the Funds’ CODM, which has determined that the Funds operates as a single segment. The CODM monitors the operating results of the Funds, as a whole, and the Funds’ long-term strategic asset allocation is pre-determined in accordance with the terms of its Prospectuses, based on the defined investment strategies that are executed by the Portfolios’ various portfolio management teams. The financial information, in the form of the Portfolios’ holdings, total returns, expense ratios, and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions) are used by the CODM to assess the segment’s performance versus the Portfolios’ various benchmarks and to make resource allocation decisions for the Fund’s single segment, which is consistent with that presented within the Funds’ financial statements. Segment assets are reflected on the Funds’ Statements of Assets and Liabilities as “Total Assets” and significant segment expenses are listed on the Statements of Operations.
Income Taxes— The Funds adopted FASB Accounting Standards Update (ASU), No. 2023-09, Income Taxes (Topic 740) – Improvements to Income Taxes Disclosures for the annual period ended December 31, 2025. ASU No. 2023-09 requires public business entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction if material. Because the Funds do not pay a material amount of income taxes, there was not a significant impact to the income tax disclosure.

Effective September 10, 2009, Penn Series, on behalf of its Money Market Fund, PMAM, and Penn Mutual, entered into an agreement whereby PMAM and Penn Mutual may temporarily and voluntarily waive fees and/or reimburse expenses in excess of their current fee waiver and expense reimbursement commitments in an effort to maintain a minimum net distribution yield for the Money Market Fund. Under the agreement, PMAM and Penn Mutual may, subject to certain minimum yield criteria, as well as a prospective three-year reimbursement period, recapture from the Money

Table of Contents

Penn Series Funds, Inc.
Notes to Financial Statements — June 30, 2026(Unaudited)

Market Fund any fees or expenses waived and/or reimbursed under this arrangement. These reimbursement payments by the Fund to PMAM and/or Penn Mutual are not subject to any net operating expense limitations in effect at the time of such payment. This recapture could negatively affect the Fund’s future yield.
If, at the end of each month, there is no liability of PMAM and Penn Mutual to pay the Funds such excess amount, and if payments of the advisory fee or administrative and corporate services fee at the end of prior months during the preceding three fiscal years have been reduced in excess of that required to maintain expenses within the expense limitation, such excess reduction is eligible to be recaptured by PMAM and Penn Mutual and, if recaptured, would become payable by the Funds to PMAM and Penn Mutual along with the advisory fee or administrative and corporate services fee for that month, as applicable. Penn Mutual and/or PMAM’s election not to recapture the amount of any reduction and reimbursement to which it is entitled in no way impairs the rights of Penn Mutual and/or PMAM to subsequently recapture such amount, provided that such amount remains eligible for recapture and would not cause the Fund to exceed its expense limit for that fee payment period.
As of June 30, 2026, the Mid Cap Value Fund and Developed International Index Fund had waived and/or reimbursed advisory fees that are subject to potential recapture by PMAM through the periods stated below. If not recaptured, the waived and/or reimbursed advisory fees will expire according to the table below:

During the six months ended June 30, 2026, previously waived advisory fees were recaptured by PMAM. The recaptured fees are shown as recaptured advisory fees on the statement of operations and are as follows:
   
Mid Cap Value Fund $ 1,370

6 — Federal Income Taxes
Each Fund has qualified and intends to continue to qualify as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code for federal income tax purposes. As such, each Fund is required to distribute all investment company taxable income and net capital gains, if any, to its shareholders in order to avoid the imposition of entity-level federal, state, and local income taxes as well as an entity-level excise tax. Except for the Money Market Fund, to the extent any Fund had undistributed investment company taxable income and net capital gains at December 31, 2025, such undistributed investment company taxable income and net capital gains were deemed distributed as consent dividends in place of regular distributions. Accordingly, no provision has been made for federal, state, or local income and excise taxes.
Reclassification of Capital Accounts:
Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined under U.S. GAAP. These book/ tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in capital or accumulated net realized gain or net investment income, as appropriate, in the period that the differences arise. Accordingly, the following permanent differences as of December 31, 2025, primarily attributable to consent dividends, were reclassed between the following accounts:

The differences between book basis and tax basis appreciation are primarily due to wash sales, Passive Foreign Investment Companies, Partnership Investments, Trust Preferred Securities, real estate investment trust adjustments, and the treatment of certain corporate actions.
It is each Fund’s policy to continue to comply with the requirements of the Internal Revenue Code under Subchapter M, applicable to regulated investment companies, and to distribute all of its taxable income, including any net realized gains on investments, to its shareholders. Therefore, no provision is made for federal income taxes.
Management of the Funds has reviewed tax positions taken in tax years that remain subject to examination by all major tax jurisdictions, including federal (i.e., the last four tax year ends and the interim tax period since then, as applicable). Management believes that there is no tax liability resulting from unrecognized tax benefits related to uncertain tax positions taken.
7 — Derivative Financial Instruments
The Funds may trade derivative financial instruments in the normal course of investing activities to assist in managing exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include purchase options, written options, forward foreign currency exchange contracts and futures contracts.
The notional or contractual amounts of these instruments represent the investment the Funds have in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.
Futures ContractsA futures contract is a standardized contract between two parties to buy or sell a specified asset at a specified future date at a price agreed today (the future price). The party agreeing to buy the underlying asset in the future assumes a long position. The price is determined by the instantaneous equilibrium between the forces of supply and demand among competing buy and sell orders on the exchange at the time of the purchase or sale of the contract.
To the extent permitted by the investment objective, restrictions and policies set forth in the Funds’ Prospectus and Statement of Additional Information, the Funds may participate in various derivative-based transactions. The Index 500, Developed International Index and Small Cap Index Funds employ futures to maintain market exposure and otherwise assist in attempting to replicate the performance of their respective indices. These derivatives offer unique characteristics and risks that assist the Funds in meeting their investment objectives. The Funds typically use derivatives in two ways: cash equitization and return enhancement. Cash equitization is a technique that may be used by the Funds through the use of futures contracts to earn “market-like” returns with the Funds’ excess and liquidity reserve cash balances and receivables. Return enhancement can be accomplished through the use of derivatives in the Funds. By purchasing these instruments, the Funds may more effectively achieve the desired fund characteristics that assist in meeting the Funds’ investment objectives.
Futures contracts involve a number of risks, such as possible default by the counterparty to the transaction, credit risk with respect to initial and variation margins held in a brokerage account, market movement and the potential of

greater loss than if these techniques had not been used by a Fund. These investments can also increase the Fund’s share price and expose the Fund to significant additional costs.
The Limited Maturity Bond, Quality Bond, Index 500, Small Cap Index and Developed International Index Funds have entered into futures contracts during the six months ended June 30, 2026. Open futures contracts held by the Quality Bond, Index 500, Small Cap Index and Developed International Index Funds at June 30, 2026 are listed after the Fund’s Schedule of Investments. 
OptionsAn option establishes a contract between two parties concerning the buying or selling of an asset at a reference price. The buyer of the option gains the right, but not the obligation, to engage in some specific transaction on the asset, while the seller incurs the obligation to fulfill the transaction if so requested by the buyer. The price of an option derives from the difference between the reference price and the value of the underlying asset plus a premium based on the time remaining until the expiration of the option. The Funds may buy and sell options, or write options.
Options are valued daily based upon the last sale price on the principal exchange on which the option is traded. The difference between the premium received or paid, and market value of the option, is recorded as unrealized appreciation or depreciation. The net change in unrealized appreciation or depreciation is reported in the Statements of Operations. When an option is exercised, the cost of the security purchased or the proceeds of the security sale are adjusted by the amount of premium received or paid. Upon the expiration or closing of the option transaction, a gain or loss is reported in the Statements of Operations.
The Flexibly Managed Fund received premiums for options written. The risk in writing a call option is that the Funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing a put option is that the Funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying an option is that the Funds pay a premium whether or not the option is exercised. The Funds also have the additional risk that there may be an illiquid market where the Funds are unable to close the contract.
The total market value of written options held in the Flexibly Managed Fund as of June 30, 2026 can be found on the Schedule of Investments.
Forward Foreign Currency ContractsA forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are traded directly between currency traders and their customers. The contract is marked-to-market daily and the change in market value is recorded by each Fund as an unrealized gain or loss. When the contract is closed or offset with the same counterparty, the Fund records a realized gain or loss equal to the change in the value of the contract when it was opened and the value at the time it was closed or offset.
The Mid Core Value Fund and Developed International Index Fund entered into forward currency contracts in conjunction with the planned purchase or sale of foreign denominated securities in order to hedge the U.S. dollar cost or proceeds. The Fund hedged currencies in times of base currency weakness in order to reduce the volatility of returns for the local securities which the Fund owns.
Foreign forward currency contracts involve a number of risks, including the possibility of default by the counterparty to the transaction and, to the extent the portfolio manager’s judgment as to certain market movements is incorrect, the risk of losses that are greater than if the investment technique had not been used. For example, there may be an imperfect correlation between the Fund’s portfolio holdings of securities denominated in a particular currency and the forward contracts entered into by the Fund. An imperfect correlation of this type may prevent the Fund from achieving the intended hedge or expose the Fund to the risk of currency exchange loss. These investment techniques also tend to limit any potential gain that might result from an increase in the value of the hedged position. These investments can also increase the volatility of the Fund’s share price and expose the Fund to significant additional costs. The forward foreign currency contracts outstanding are listed after the Fund’s Schedule of Investments.

In order to better define their contractual rights and to secure rights that will help the Funds mitigate their counterparty risk, the Funds may participate in International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement” or “ISDA”) with derivative contract counterparties or enter into similar agreements covering foreign exchange contracts (“Fx Letters”). An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs over-the-counter (“OTC”) traded derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, a Fund may, under certain circumstances, offset with the counterparty certain derivative financial instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (closeout netting) including the bankruptcy or insolvency of the counterparty. Also, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events. An Fx Letter is also a bilateral agreement between a Fund and a counterparty and is limited to cover only foreign exchange contracts. Fx Letters typically contain netting provisions covering events of default and do not require collateral to be posted. ISDAs and Fx Letters containing netting provisions may be referred to as Master Netting Agreements (“MNA”).
Collateral and margin requirements differ by type of derivative. Margin requirements are established by the broker for OTC traded derivatives or by the clearing house for exchange traded derivatives. Brokers can ask for margining in excess of the minimum in certain circumstances. Collateral terms are contract specific for OTC derivatives (foreign currency exchange contracts and options). For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by a Fund and the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold before a transfer has to be made. To the extent amounts due to a Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty non-performance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

In third party Margin Direct ACA arrangement, the collateral provider (the Pledgor) posts collateral to a segregated account in the name of the Pledgor designated as pledged for the benefit of the collateral receiver (the “Secured Party”). Prior to an event of default, The Secure Party is not permitted to re-sell, re-use or re-pledge the collateral.

8 — Credit and Market Risk
The Funds may invest a portion of their assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended,
178

Table of Contents

Penn Series Funds, Inc.
Notes to Financial Statements — June 30, 2026(Unaudited)

and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Funds’ ability to dispose of them in a timely manner and at a fair price when it is necessary or preferable to do so.
The high yield securities in which the High Yield Bond Fund may invest are predominantly speculative as to the issuer’s continuing ability to meet principal and interest payments. The value of the lower quality securities in which the High Yield Bond Fund may invest will be affected by the credit worthiness of individual issuers, general economic and specific industry conditions, and will fluctuate inversely with changes in interest rates. In addition, the secondary trading market for lower quality bonds may be less active and less liquid than the trading market for higher quality bonds.
The funds may invest in securities of foreign issuers in various countries. These investments may involve certain considerations and risks not typically associated with investments in the United States, as a result of, among other factors, the possibility of future political and economic developments and the level of governmental supervision and regulation of securities markets in the respective countries.
Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Funds or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded.
9 —  Contractual Obligations
In the general course of business, the Funds enter into contracts that contain a variety of representations and warranties and which provide general indemnification. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds and/or its affiliates that have not yet occurred. However, based on experience, management of the Funds expects the risk of loss to be remote.
10 —  Subsequent Events
Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that no additional subsequent events require recognition or disclosure in the financial statements.

Board Approval of New Sub-Advisory Agreements
Nomura Investments Fund Advisers - Mid Cap Growth Fund and Large Core Growth Fund.
On December 1, 2025, Nomura Holding America Inc. (“Nomura”) completed its acquisition of Macquarie Asset Management’s U.S. and European public investments business, including Macquarie Management Holdings, Inc. (“MMHI”), the parent company of Delaware Investments Fund Advisers (“DIFA”) (the “Nomura Acquisition”), investment sub-adviser to the Mid Cap Growth Fund and Large Core Growth Fund (for this section only, each, a “Fund” and together, the “Funds”). The Nomura Acquisition constituted a change of control of DIFA, which, in turn, caused the assignment and, pursuant to Section 15 of the Investment Company Act of 1940 (the “1940 Act”), the automatic termination of the Funds’ investment sub-advisory agreement between Penn Mutual Asset Management, LLC (“PMAM” or the “Adviser”) and DIFA (the “Prior DIFA Sub-Advisory Agreement”). In addition, as part of the Nomura Acquisition, DIFA was renamed Nomura Investments Fund Advisers (“NIFA”). In anticipation of the Nomura Acquisition and the automatic termination of the Prior DIFA Sub-Advisory Agreement, at a meeting of the Penn Series Funds, Inc.’s (the “Company”) Board of Directors (the “Board”) held on September 17, 2025 (for this section only, the “Meeting”), PMAM recommended, and the Board, including a majority of the Directors who are not “interested persons,” as defined by the 1940 Act, of the Company (collectively, the “Independent Directors”), approved a new sub-advisory agreement between PMAM and NIFA with respect to the Funds, which became effective December 1, 2025 (for this section only, the “New Sub-Advisory Agreement”).
Board Considerations. Prior to the approval of the New Sub-Advisory Agreement, the Board received written and oral information from PMAM and NIFA1, as well as considered information provided by NIFA at the May 2025 board meeting (the “May Board Meeting”) in connection with the annual renewal of the firm’s investment sub-advisory agreement. PMAM reviewed with the Board the basis for its recommendation, including NIFA’s performance with respect to its management of the Funds. The Board also reviewed and considered information about NIFA’s portfolio managers, research, investment and risk management processes, as well as other factors. The Board then considered information about the Nomura Acquisition and its anticipated effect on NIFA, including that according to NIFA, no changes were expected to its advisory business. The Board discussed the written materials provided in advance of the meeting, as well as other information the Board received during the meeting, and deliberated on the approval of the New Sub-Advisory Agreement in light of this information. As further outlined below, in approving the New Sub-Advisory Agreement, the Board carefully evaluated: (1) the nature, extent and quality of the services rendered by NIFA to each Fund to date and the expectation of the continuation of such services; (2) each Fund’s performance, as well as the performance of similar accounts managed by NIFA; (3) the costs of the services provided by NIFA and the profitability of NIFA with respect to each Fund; and (4) the extent to which economies of scale would be realized as each Fund grows and whether each Fund’s sub-advisory fee levels reflect those economies of scale for the benefit of each Fund’s investors. The Board evaluated the foregoing information, as well as such other information as the Directors considered to be relevant in the exercise of their reasonable judgment, in their decision to approve the New Sub-Advisory Agreement.
Nature, Extent and Quality of Advisory Services. In considering the nature, extent and quality of the services to be provided by NIFA, the Board evaluated, among other things, NIFA’s business, personnel, experience, investment decision process, brokerage practices, compliance program, and the resources of NIFA to be dedicated to each Fund. The Board also noted that NIFA planned to retain the same investment processes, portfolio management personnel and other support systems as are currently in place. The Board observed that it had previously approved NIFA’s code of ethics and compliance program, that the Chief Compliance Officer of the Funds continues to monitor the code and the program, and that no material changes to the code of ethics or compliance program are anticipated post-Nomura Acquisition. The Board reviewed the change in control at NIFA noting PMAM’s comfort with the financial strength of Nomura. The Board recalled its considerations regarding the firm at the May Board Meeting, including its conclusion that the Sub-Adviser was in a position to provide a high quality level of services to the Funds. The Board noted its view that, based on the information it has received, the Nomura Acquisition should not affect that conclusion. Based on its evaluation, the Board concluded, within the context of its full deliberations, that the nature, extent and quality of services to be provided by NIFA to each Fund, supported the approval of the New Sub-Advisory Agreement.
Performance Record. The Board considered each Fund’s performance in determining whether to approve the New Sub-Advisory Agreement. In this regard, the Board considered its review of each Fund’s performance at the May Board Meeting. For the May Board Meeting review, PMAM engaged an independent third party to prepare a report (the “Comparative Report”) to help the Board evaluate, among other information, each Fund’s performance and the performance of its peer funds (“Peer Funds”).
1 At the time of the Board’s review prior to December 1, 2025, NIFA was named DIFA, but for ease of reference, this document hereinafter references NIFA even for periods prior to December 1, 2025.

Board Approval of New Sub-Advisory Agreements (continued)
Specifically, the Board considered each Fund’s recent and long-term performance relative to the Fund’s applicable benchmark and to its Peer Funds. In evaluating performance, the Board considered recent market conditions, economic and market trends, as well as both market risk and shareholder risk expectations for a Fund. The Board also reviewed more recent performance information since the May Board Meeting. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the performance of the Funds, both compared to the applicable benchmark and to Peer Funds, supported the approval of the New Sub-Advisory Agreement.
Costs of Advisory Services. In considering the cost of the sub-advisory services to be provided by NIFA, the Board evaluated (a) the services to be provided by NIFA; (b) the sub-advisory fees to be paid to NIFA, including the breakpoints in the sub-advisory fee schedule under the New Sub-Advisory Agreement; (c) the advisory fees to be paid to PMAM in comparison to advisory fees charged to other comparable mutual funds and other types of comparable accounts; and (d) the fact that NIFA will be compensated by PMAM and not by each Fund directly and that such compensation reflects an arms-length negotiation between PMAM and NIFA. The Board noted that the sub-advisory fee payable to NIFA would remain the same under the New Sub-Advisory Agreement as it was under the Prior DIFA Sub-Advisory Agreement, and that each Fund’s shareholders would not experience a change in the advisory fee rate in connection with the approval of the New Sub-Advisory Agreement. The Board recalled its review, at the May Board Meeting, of comparative fees and the costs of services to be provided under the Prior DIFA Sub-Advisory Agreement. The Board observed that fees paid under the New Sub-Advisory Agreement are identical to those paid under the Prior DIFA Sub-Advisory Agreement, which were reviewed and approved in May 2025. Based on its evaluation, the Board concluded, within the context of its full deliberations, that the sub-advisory fee charged under the New Sub-Advisory Agreement is reasonable and supported approval of the New Sub-Advisory Agreement.
Profitability and Other Benefits. Noting that NIFA is compensated by PMAM at a rate negotiated at arm’s length, the Board determined the profits realized by NIFA are not unreasonable. The Board also considered the other or fall-out benefits that may accrue to NIFA because of its relationship with each Fund, including the receipt of indirect benefits for portfolio securities trades placed with each Fund’s assets. In addition, the Board considered that NIFA may benefit from the development of additional investment advisory business with PMAM or the Company as a result of its relationship with each Fund. Based on its evaluation, the Board concluded that the profitability of and any fall-out benefits that may be realized by NIFA would be reasonable.
Economies of Scale. The Board considered the existence of any economies of scale and whether any such economies of scale would be passed along to each Fund’s shareholders through a graduated investment advisory fee schedule (i.e., breakpoints) or other means. The Board also noted that PMAM and The Penn Mutual Life Insurance Company (“Penn Mutual”) have contractually committed to waive fees and/or reimburse certain expenses of the Mid Cap Growth Fund and the Large Core Growth Fund to maintain each Fund’s total expense ratio at 1.00% and 0.90%, respectively. Based on its evaluation, the Board concluded, within the context of its full deliberations, that each Fund and its shareholders obtain a reasonable benefit from any economies of scale realized by PMAM and NIFA.
Based on the Board’s deliberations and its evaluation of the information described above, the Board, including all of the Independent Directors, unanimously approved the New Sub-Advisory Agreement and concluded that the compensation under the New Sub-Advisory Agreement is fair and reasonable in light of such services and such other matters as the Board considered to be relevant in the exercise of the Directors’ reasonable judgment. In the course of its deliberations, the Board did not identify any particular information or single factor that was all-important or controlling.
Janus Henderson Investors US LLC - Mid Cap Value Fund and Small Cap Growth Fund.
On June 30, 2026, a consortium of investors led by Trian Fund Management, L.P. (“Trian”) and General Catalyst Group Management, LLC (“General Catalyst”) completed an acquisition of Janus Henderson Group plc (the “Janus Acquisition”), the indirect parent company of Janus Henderson Investors US LLC (“Janus”). At the closing, Janus Henderson Group plc changed its name to Janus Henderson Group Ltd. and became an indirect, wholly owned subsidiary of Jupiter Topco LLC. Janus remains an indirect wholly-owned subsidiary of Janus Henderson Group Ltd. (formerly plc), but the Janus Acquisition constituted a change of control of Janus, which, in turn, caused the assignment and, pursuant to Section 15 of the 1940 Act, the automatic termination of the Funds’ investment sub-advisory agreement between PMAM and Janus dated May 1, 2020, as amended (the “Prior Janus Sub-Advisory Agreement”). PMAM and Janus entered into the Prior Janus Sub-Advisory Agreement with respect to the Mid Cap Value Fund and the Small Cap Growth Fund on May 1, 2020. Under the terms of the Prior Janus Sub-Advisory Agreement, Janus was responsible for making the day-to-day investment decisions for the assets of

each Fund and continuously reviewing, supervising and administering each Fund’s investment program. At a meeting of the Company’s Board held on May 21, 2026, PMAM recommended, and the Board, including the Independent Directors, approved a new Sub-Advisory Agreement, which became effective June 30, 2026 (for this section only, the “New Sub-Advisory Agreement”).
Board Considerations.Prior to the approval of the New Sub-Advisory Agreement, the Board received written and oral information from PMAM and Janus, as well as considered information provided by Janus in connection with the annual renewal of Janus’s investment sub-advisory agreement. PMAM reviewed with the Board the basis for its recommendation, including Janus’s performance with respect to its management of the Funds. The Board also reviewed and considered information about Janus’s portfolio managers, research, investment and risk management processes, as well as other factors. The Board then considered information about the Janus Acquisition and its anticipated effect on Janus, including that, according to Janus, no changes were expected to its advisory business, and that as a private company, Janus Henderson Group Ltd. (formerly plc) would continue to be led by the current management team and would maintain its main presence in both London, England, and Denver, Colorado. The Board discussed the written materials provided in advance of the meeting, as well as other information the Board received during the meeting, and deliberated on the approval of the New Sub-Advisory Agreement in light of this information. As further outlined below, in approving the New Sub-Advisory Agreement, the Board carefully evaluated: (1) the nature, extent and quality of the services rendered by Janus to each Fund to date and the expectation of the continuation of such services; (2) each Fund’s performance, as well as the performance of similar accounts managed by Janus; (3) the costs of the services provided by Janus and the profitability of Janus with respect to each Fund; and (4) the extent to which economies of scale would be realized as each Fund grows and whether each Fund’s sub-advisory fee levels reflect those economies of scale for the benefit of each Fund’s investors. The Board evaluated the foregoing information, as well as such other information as the Directors considered to be relevant in the exercise of their reasonable judgment, in their decision to approve the New Sub-Advisory Agreement. 
Nature, Extent and Quality of Advisory Services. In considering the nature, extent and quality of the services to be provided by Janus, the Board evaluated, among other things, Janus’s business, personnel, experience, investment decision process, brokerage practices, compliance program, and the resources of Janus to be dedicated to each Fund. The Board also noted that Janus planned to retain the same investment processes, portfolio management personnel and other support systems as are currently in place and considered Janus’ commitment to allocate the resources necessary to ensure services remain at least at current levels. The Board noted that Janus intends to take appropriate steps to retain key personnel supporting the Funds, including key investment, compliance, operational and administrative personnel who support Fund oversight. The Board observed that it had previously approved Janus’s code of ethics and compliance program, that the Chief Compliance Officer of the Funds continues to monitor the code and the program, and that no material changes to the code of ethics or compliance program are anticipated post-Janus Acquisition. The Board also considered certain materials related to its renewal of Janus’s investment sub-advisory agreement, which occurred at the same Board Meeting, including its conclusion that Janus was in a position to provide a high-quality level of services to the Funds. The Board noted its view that, based on the information it has received, the Janus Acquisition should not affect that conclusion. Based on its evaluation, the Board concluded, within the context of its full deliberations, that the nature, extent and quality of services to be provided by Janus to each Fund supported the approval of the New Sub-Advisory Agreement.
Performance Record. The Board considered each Fund’s performance in determining whether to approve the New Sub-Advisory Agreement. PMAM engaged an independent third party to prepare the Comparative Report to help the Board evaluate, among other information, each Fund’s performance and the performance of its Peer Funds. Specifically, the Board considered each Fund’s recent and long-term performance relative to the Fund’s applicable benchmark and to its Peer Funds. In evaluating performance, the Board considered recent market conditions, economic and market trends, as well as both market risk and shareholder risk expectations for a Fund. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the performance of the Funds, both compared to the applicable benchmark and to Peer Funds, supported the approval of the New Sub-Advisory Agreement.
Costs of Advisory Services. In considering the cost of the sub-advisory services to be provided by Janus, the Board evaluated (a) the services to be provided by Janus; (b) the sub-advisory fees to be paid to Janus; (c) the advisory fees to be paid to PMAM in comparison to advisory fees charged to other comparable mutual funds and other types of comparable accounts; and (d) the fact that Janus will be compensated by PMAM and not by each Fund directly and that such compensation reflects an arms-length negotiation between PMAM and Janus. The Board noted that the sub-advisory fee payable to Janus would remain

the same under the New Sub-Advisory Agreement as it was under the Prior Janus Sub-Advisory Agreement, and that each Fund’s shareholders would not experience a change in the advisory fee rate in connection with the approval of the New Sub-Advisory Agreement. The Board reviewed comparative fees and the costs of services to be provided under the Prior Janus Sub-Advisory Agreement, which were reviewed and approved at the same meeting. Based on its evaluation, the Board concluded, within the context of its full deliberations, that the sub-advisory fee charged under the New Sub-Advisory Agreement is reasonable and supported the approval of the New Sub-Advisory Agreement.
Profitability and Other Benefits. Noting that Janus is compensated by PMAM at a rate negotiated at arm’s length, the Board determined the profits realized by Janus were not unreasonable. The Board also considered the other or fall-out benefits that may accrue to Janus because of its relationship with each Fund, including that Janus may benefit from the development of additional investment advisory business with PMAM or the Company. Based on its evaluation, the Board concluded that the profitability of and any fall-out benefits that may be realized by Janus would be reasonable.
Economies of Scale. The Board considered the existence of any economies of scale and whether any such economies of scale would be passed along to each Fund’s shareholders through a graduated investment advisory fee schedule (i.e., breakpoints) or other means. The Board also noted that PMAM and Penn Mutual have contractually committed to waive fees and/or reimburse certain expenses of the Mid Cap Value Fund and Small Cap Growth Fund to maintain each Fund’s total expense ratio at 0.83% and 1.13%, respectively. Based on its evaluation, the Board concluded, within the context of its full deliberations, that each Fund and its shareholders obtain a reasonable benefit from any economies of scale realized by PMAM and Janus.
Based on the Board’s deliberations and its evaluation of the information described above, the Board, including all of the Independent Directors, unanimously approved the New Sub-Advisory Agreement and concluded that the compensation under the New Sub-Advisory Agreement is fair and reasonable in light of such services and such other matters as the Board considered to be relevant in the exercise of the Directors’ reasonable judgment. In the course of its deliberations, the Board, and each Director thereof, did not identify any particular piece of information or single factor that was all-important or controlling.

Annual Board Approval of Investment Advisory and Sub-Advisory Agreements
The Company and PMAM have entered into an investment advisory agreement (the “Advisory Agreement”) pursuant to which PMAM serves as the investment adviser to each series of the Company (each, a “Fund” and collectively, the “Funds”). As the investment adviser to the Funds, PMAM is primarily responsible for (i) providing day-to-day investment management services to certain of the Funds (collectively, the “Directly Managed Funds”) and (ii) selecting and overseeing the investment sub-advisers who perform day-to-day investment management services for the remaining Funds (collectively, the “Sub-Advised Funds”). The Directly Managed Funds consist of the Money Market, Limited Maturity Bond, Quality Bond, High Yield Bond, Balanced, Aggressive Allocation, Moderately Aggressive Allocation, Moderate Allocation, Moderately Conservative Allocation, and Conservative Allocation Funds. The Sub-Advised Funds consist of the Flexibly Managed, Large Growth Stock, Large Cap Growth, Large Core Growth, Large Cap Value, Large Core Value, Index 500, Mid Cap Growth, Mid Cap Value, Mid Core Value, SMID Cap Growth, SMID Cap Value, Small Cap Value, Small Cap Growth, Small Cap Index, Developed International Index, International Equity, Emerging Markets Equity, and Real Estate Securities Funds.           
PMAM has entered into, and the Company’s Board has approved, separate sub-advisory agreements (each, a “Sub-Advisory Agreement”, collectively, the “Sub-Advisory Agreements”, and together with the Advisory Agreement, the “Agreements”) with each sub-adviser identified below (each, a “Sub-Adviser”, collectively, the “Sub-Advisers”, and together with PMAM, the “Advisers”). Each Sub-Adviser is primarily responsible for the day-to-day management of its Sub-Advised Funds subject to the oversight of both PMAM and the Board. PMAM serves as “manager of managers” with respect to the Sub-Advisers and the Sub-Advised Funds. As such, PMAM, pursuant to an exemptive order issued by the U.S. Securities and Exchange Commission and subject to certain conditions and the approval of the Board, may hire and terminate unaffiliated investment sub-advisers without shareholder approval for each of the Sub-Advised Funds. The Sub-Advised Funds’ “manager of managers” structure facilitates PMAM’s regular review of each Sub-Adviser’s overall performance with respect to the Sub-Advised Fund(s) it manages. When selecting a new investment sub-adviser, PMAM quantitatively and qualitatively evaluates, among other factors, each sub-adviser’s (i) investment expertise and resources, (ii) investment results in managing assets for relevant asset classes, investment styles and strategies, and (iii) regulatory compliance infrastructure and culture. PMAM engages in a

substantially similar evaluation process when determining whether to retain a Sub-Adviser. PMAM also oversees each Sub-Adviser’s investment activities with respect to each Fund it manages to seek to ensure compliance with the Fund’s investment policies and guidelines and to monitor each Sub-Adviser’s adherence to its investment style and the Fund’s investment strategies.

The 1940 Act requires that each Fund’s initial Advisory Agreement and Sub-Advisory Agreement, as well as the continuation thereof, be specifically approved by: (i) the vote of the Board or by a vote of the shareholders of the Fund; and (ii) the vote of a majority of the Independent Directors, cast in person at a meeting called for the purpose of voting on such approval. In connection with its consideration of such approvals, the Board must request and evaluate, and the Advisers are required to furnish, such information as may be reasonably necessary for the Board to evaluate the terms of the Agreements.
Board Approval of the Continuance of Investment Advisory and Sub-Advisory Agreements
The Board held a special meeting on May 12, 2026 (the “Pre-15(c) Meeting”) via web conference and an in-person meeting on May 21, 2026 (the “May Meeting” and together with the Pre-15(c) Meeting, the “Meetings”) to consider the approval of each Agreement with respect to each Fund. In preparation for the Pre-15(c) Meeting, the Board provided PMAM with a written request for information relating to both PMAM and each Sub-Adviser and received and reviewed, in advance of the Pre-15(c) Meeting, extensive written materials in response to that request. After the Pre-15(c) Meeting, the Independent Directors also requested additional follow-up information from PMAM. The materials provided included information pertaining to (i) PMAM’s and each Sub-Adviser’s leadership, organizational structure, corporate changes, and financial condition, (ii) the performance of each Fund versus its benchmark and Peer Funds, as identified by an independent third party, (iii) the level of the investment advisory fees, sub-advisory fees and overall expense ratios of each Fund, as applicable, as well as comparisons of such fees and expenses with those incurred by each Fund’s Peer Funds, (iv) the costs to each Adviser of providing such services, including a profitability analysis applicable to PMAM and its affiliates, (v) each Adviser’s risk management and compliance program, and (vi) various other matters relevant to the operations of and services provided by each Adviser.
In addition to the information provided by the Advisers, the Board also considered the detailed Fund information the Board receives and reviews during the course of the year, including Fund-specific performance and fees and expenses information provided on a quarterly basis. The Board also received and reviewed a memorandum from legal counsel discussing the responsibilities of the Independent Directors in connection with their consideration of the continuation of the Agreements. In

Board Approval of the Continuance of Investment Advisory and Sub-Advisory Agreements (continued)
the course of their deliberations, the Independent Directors met both with senior representatives of PMAM and in executive session outside the presence of management to discuss the information submitted to the Board in connection with the renewal of the Agreements.
At the May Meeting, following its deliberations, the Board, including all of the Independent Directors voting separately, unanimously determined, in the exercise of the Directors’ business judgment, to approve the continuance and renewal of the applicable Agreements for another year with respect to each Fund.
Board Considerations
With respect to each Adviser, the Board evaluated a number of factors, including among others: (a) the nature, extent and quality of each Adviser’s investment management and other services and, with respect to PMAM, its services as a “manager of managers” of the Sub-Advised Funds; (b) the quantity and quality of each Adviser’s investment management personnel; (c) each Adviser’s operations and financial condition; (d) each Adviser’s brokerage practices (including best execution policies, evaluating execution quality, average commission rates on fund trades, soft dollar arrangements, if any, and affiliated and directed brokerage arrangements) and investment strategies; (e) an independently prepared report comparing the Funds’ advisory and sub-advisory fees and overall expense ratios to the fees and expenses charged to comparable funds and accounts, including breakpoints; (f) the level of each Adviser’s cost of services provided and estimated profitability from its fund-related operations; (g) other benefits that may accrue to each Adviser and its affiliates as a result of their relationship with the Funds; (h) the extent to which the Funds’ advisory and sub-advisory fees reflect economies of scale and the extent to which any such economies of scale are shared with fund investors; (i) each Adviser’s risk management and compliance programs and, if applicable, a description of the material changes made to, and material compliance violations under, the compliance program; (j) each Adviser’s investment reputation, expertise and resources; and (k) an independently-prepared report of each Fund’s performance compared with that of its Peer Funds. In its deliberations, the Directors did not identify any single piece of information that was all-important or controlling, noting that each Director could attribute different weights to the various factors considered.
During the Meetings, representatives from PMAM commented on the information delivered to the Board and answered questions from the Directors to help the Board evaluate each Adviser’s fees and other aspects of the services provided, including the services provided by PMAM’s affiliates and the fees related to such services. The Board then deliberated on the continuation of the Agreements in light of all of the information provided.
In considering the continuance and renewal of the Agreements, the Board considered the following factors and reached the following conclusions:
Nature, Extent and Quality of Services. The Board considered the nature, extent and quality of the services provided by each Adviser to the Funds. In this regard, the Board evaluated, among other things, each Adviser’s: business; personnel; experience; investment decision processes; past performance; brokerage practices; compliance infrastructure and program; and resources to be dedicated to each Fund, as applicable. The Board reviewed the scope of services to be provided by each Adviser under the Agreements and noted that there would be no significant differences between the scope of services provided by the Advisers for the past year and the scope of services to be provided during the upcoming year. The Board also considered each Adviser’s representations to the Board that the Adviser would continue to provide investment and related services that were of materially the same nature and quality as services provided to the Funds in the past, and that these services are appropriate in scope and extent for the Funds’ operations, the competitive landscape of the investment company business, and investor needs. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the nature, extent and quality of services provided by each Adviser to the Funds supported renewal of the Agreements.
Fund Performance. The Board considered fund performance in determining whether to continue the Agreements. PMAM engaged an independent third party to prepare the Comparative Report to help the Board evaluate, among other information, each Fund’s performance and the performance of its Peer Funds. Specifically, the Board considered each Fund’s recent and long-term performance relative to the Fund’s applicable benchmark and to its Peer Funds. In evaluating performance, the Board considered the market conditions of the past year, economic and market trends, as well as both market risk and shareholder risk expectations for a given Fund. Where a Fund significantly underperformed or outperformed its Peer Funds, the Board considered the Adviser’s explanation as to the reasons for the underperformance or outperformance. The Board also considered the Adviser’s explanation as to why certain Peer Funds selected by the independent provider may not have provided
186

Board Considerations (continued)
a close comparison, due to differences in investment quality or the style of investment strategy followed by the Fund. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the performance of the Funds, both compared to the applicable benchmark and to Peer Funds, supported renewal of the Agreements.
Costs of Advisory and Sub-Advisory Services. The Board considered the cost of the advisory and sub-advisory services provided to the Funds by each Adviser. The Board considered, in particular, the expense information for the Funds and the corresponding Peer Funds included in the Comparative Report. The Board evaluated (a) the advisory and sub-advisory services provided; (b) the advisory and sub-advisory fees paid, as well as the impact of recently reduced advisory and sub-advisory fees to be charged for certain Funds to the extent not yet completely reflected in the Comparative Report; (c) the advisory and sub-advisory fees paid in comparison to the advisory and sub-advisory fees charged to the Peer Funds; and (d) the fact that each Sub-Adviser is compensated by PMAM and not directly by the relevant Sub-Advised Fund, and that such compensation reflects an arms-length negotiation between each Sub-Adviser and PMAM. The Board also considered PMAM and its affiliates’ ongoing agreement to waive the Funds’ management and other fees to prevent total fund expenses from exceeding a specified cap. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the advisory and sub-advisory fees charged to the Funds are fair and reasonable and supported the renewal of the Agreements.
Profitability and Other Benefits. With regard to profitability and fall-out benefits, the Board considered all compensation paid by a Fund, directly or indirectly, to each Adviser and its affiliates, and any benefits derived or to be derived by each Adviser and its affiliates, as well as the cost of Fund services provided by each Adviser. The Board noted that PMAM’s overall profitability had slightly decreased during the past year. In its consideration of the profitability of PMAM and its affiliates, the Board was provided with and considered information pertaining to the profitability of the administrative and servicing arrangements between the Funds and PMAM and Penn Mutual. The Board also considered the expense allocation methodology, which was unchanged from that used in the prior year, used to determine the profitability of PMAM and its affiliates and the Peer Fund expense information included in the Comparative Report, which included servicing-related expenses. The Board noted that while such information may not constitute a perfect comparison due to differences in the types and extent of the services provided to the Peer Funds, the information nonetheless provided a useful data point. When considering the profitability of each Sub-Adviser, the Board considered the fact that each Sub-Adviser is compensated by PMAM, and not by the Funds directly, and such compensation reflects an arms-length negotiation between the Sub-Adviser and PMAM. In evaluating the other or fall-out benefits that may accrue to the Sub-Advisers and their affiliates because of their relationship with the Funds, the Board noted that certain of the Sub-Advisers may receive indirect benefits in the form of soft dollar arrangements for portfolio securities trades placed with the Funds’ assets. In addition, the Board considered that the Sub-Advisers may benefit from the development of additional investment advisory business with PMAM or the Company as a result of their relationships with the Funds. Based on this evaluation, the Board concluded, within the context of its full deliberations, that the profitability of and any fall-out benefits realized by the Advisers are reasonable in relation to the quality of their respective services and supported renewal of the Agreements.
Economies of Scale. The Board considered the existence of any economies of scale and whether the benefits of any such economies of scale are shared with a Fund and its shareholders, including through breakpoints in the advisory and sub-advisory fee schedules. The Board noted the existing breakpoints provided in certain advisory and sub-advisory fee schedules, as applicable. The Board further noted PMAM’s continued focus on evaluating advisory and sub-advisory fee breakpoints to allow each Fund and its shareholders to benefit from economies of scale, as applicable. The Board also noted PMAM’s expectations for a projected asset decline for the Funds based on the outlook for sales of Penn Mutual’s existing variable products that offer the Funds as investment options. As a result, the Board concluded that should an Adviser realize economies of scale in connection with its management of one or more Funds, the existing fee structures of the Funds adequately ensure that the benefits derived from any such economies of scale are reasonably shared with the Fund and its shareholders.

Board Approval of Amended Sub-Advisory Agreements with GSAM, AllianceBernstein, American Century, NIFA, Eaton Vance, Cohen & Steers, MFS, Vontobel, and TRP
At the May Meeting, the Board, including all of the Independent Directors, considered and unanimously approved: (i) an amendment to the Investment Sub-Advisory Agreement (the “Amended GSAM Agreement”) between the Adviser and Goldman Sachs Asset Management, L.P. (“GSAM”) modifying the sub-advisory fee rates paid by the Adviser to GSAM for the services provided to the Small Cap Value Fund and SMID Cap Growth Fund; (ii) an amendment to the Investment Sub-Advisory

Board Approval of Amended Sub-Advisory Agreements with GSAM, AllianceBernstein, American Century, NIFA, Eaton Vance, Cohen & Steers, MFS, Vontobel, and TRP (continued)
Agreement (the “Amended AB Agreement”) between the Adviser and AllianceBernstein L.P. (“AllianceBernstein”) modifying the sub-advisory fee rates paid by the Adviser to AllianceBernstein for the services provided to the Large Cap Value Fund and SMID Cap Value Fund; (iii) an amendment to the Investment Sub-Advisory Agreement (the “Amended American Century Agreement”) between the Adviser and American Century Investment Management, Inc. (“American Century”) modifying the sub-advisory fee rate paid by the Adviser to American Century for the services provided to the Mid Core Value Fund; (iv) an amendment to the Investment Sub-Advisory Agreement (the “Amended NIFA Agreement”) between the Adviser and NIFA modifying the sub-advisory fee rate paid by the Adviser to NIFA for the services provided to the Large Core Growth Fund; (v) an amendment to the Investment Sub-Advisory Agreement (the “Amended Eaton Vance Agreement”) between the Adviser and Eaton Vance Management (“Eaton Vance”) modifying the sub-advisory fee rate paid by the Adviser to Eaton Vance for the services provided to the Large Core Value Fund; (vi) an amendment to the Investment Sub-Advisory Agreement (the “Amended Cohen & Steers Agreement”) between the Adviser and Cohen & Steers Capital Management, Inc. (“Cohen & Steers”) modifying the sub-advisory fee rate paid by the Adviser to Cohen & Steers for the services provided to the Real Estate Securities Fund; (vii) an amendment to the Investment Sub-Advisory Agreement (the “Amended MFS Agreement”) between the Adviser and MFS Investment Management (“MFS”) modifying the sub-advisory fee rate paid by the Adviser to MFS for the services provided to the Large Cap Growth Fund; (viii) an amendment to the Investment Sub-Advisory Agreement (the “Amended Vontobel Agreement”) between the Adviser and Vontobel Asset Management, Inc. (“Vontobel”) modifying the sub-advisory fee rates paid by the Adviser to Vontobel for the services provided to the International Equity Fund and Emerging Markets Equity Fund; and (ix) an amendment to the Investment Sub-Advisory Agreement (the “Amended TRP Agreement”) between the Adviser and T. Rowe Price Associates, Inc. (“TRP”) modifying the sub-advisory fee rate paid by the Adviser to TRP for the services provided to the Large Growth Stock Fund (collectively, the “Amended Agreements”). Each Amended Agreement, if approved, was scheduled to take effect on June 1, 2026.
In preparation for the Meetings, the Board received and reviewed written materials related to the proposed changes to the sub-advisory fee rates. The materials provided included information pertaining to (i) each Sub-Adviser’s leadership, organizational structure, corporate changes, and financial condition, (ii) the performance of each Fund versus its benchmark and Peer Funds, as identified by an independent third party, (iii) the level of the investment advisory fees, sub-advisory fees and overall expense ratios of each Fund, as applicable, as well as comparisons of such fees and expenses with those incurred by each Fund’s Peer Funds, (iv) the costs to each Sub-Adviser of providing such services, including a profitability analysis applicable to PMAM and the Sub-Adviser, (v) each Sub-Adviser’s risk management and compliance program, and (vi) various other matters relevant to the operations of and services provided by each Sub-Adviser.
The Directors recognized that the existing sub-advisory agreements (the “Existing Sub-Advisory Agreements”) for the Small Cap Value Fund, SMID Cap Growth Fund, Large Cap Value Fund, SMID Cap Value Fund, Mid Core Value Fund, Large Core Growth Fund, Real Estate Securities Fund, Large Core Value Fund, Large Cap Growth Fund, International Equity Fund, Emerging Markets Equity Fund, and Large Growth Stock Fund (each, a “Fund,” and collectively, the “Funds”) were reviewed by the Board and discussed with the Adviser earlier in the Meetings in connection with their annual renewal and that the Directors’ conclusions may take into account conclusions reached during their consideration of these Existing Sub-Advisory Agreements.
In considering whether to approve the Amended Agreements, the Board considered and discussed a substantial amount of information and analysis provided by the Adviser at the Meetings, as well as at prior Board meetings. The Board had the opportunity to request additional information in connection with its considerations and to discuss this information with Adviser personnel, including representatives from the compliance and finance departments, and investment personnel. The Board engaged in substantive discussions with them concerning the proposal. The Board also was advised of its legal responsibilities and obligations by Fund counsel.
The Board also recognized that, except for the effective date, the fee schedule, and minor non-material updates, the terms of the Amended Agreements and the terms of the corresponding Existing Sub-Advisory Agreement were substantially identical. In determining to approve the Amended Agreements with respect to each Fund, the Board considered at the Meetings the same factors it reviewed and conclusions it reached, as applicable, in connection with its annual renewal of the Existing Sub-Advisory Agreements, including the Board’s general satisfaction with the nature and quality of the services being provided by the applicable Sub-Adviser, and focused its review on the potential impact of the change in sub-advisory fees on these factors and conclusions. In connection with its evaluation of each Amended Agreement, the Board considered the following factors:

Nature, Extent and Quality of Services. The Board considered the nature, extent and quality of the services provided by each Sub-Adviser to the Funds and the resources of the Sub-Adviser dedicated to the support of the applicable Funds. In this regard, the Directors evaluated, among other things, the Sub-Adviser’s personnel, experience, track record and compliance program. The Directors found the level of each Sub-Adviser’s professional staff and culture of compliance satisfactory. The Board also considered that each Sub-Adviser had provided a certification to the Board that there would be no changes to the type and quality of services provided by the Sub-Adviser in connection with the proposed fee modifications. Following its evaluation, the Board concluded that, within the context of its full deliberations, the nature, extent and quality of services provided by each Sub-Adviser to each respective Fund and the resources of each Sub-Adviser supported the approval of each Amended Agreement.
Fund Performance. The Board considered each Fund’s performance in determining whether to approve the corresponding Amended Agreement. Specifically, the Directors considered each Fund’s performance relative to its peer groups and appropriate indices/benchmarks, in light of total return, yield and market trends. For purposes of evaluating the performance of each Fund, the Board also considered discussions with the Adviser and each Sub-Adviser about Fund investment performance that occurred earlier at the Meetings and at prior Board meetings. The Board also noted that it had reviewed each Sub-Adviser’s performance through its oversight of its management of the applicable Funds since its appointment as sub-adviser to the Funds. In evaluating performance, the Directors considered both market risk and shareholder risk expectations for the Funds. The Board also took into account factors including general market conditions, interest rate and inflation levels, and credit conditions. Following evaluation, the Board concluded that, within the context of its full deliberations, the performance of each Fund supported the approval of the applicable Amended Agreement.
Fund Expenses. With respect to each Fund’s expenses, the Directors considered the effect of the proposed modifications to the Fund’s sub-advisory fee rate schedules. In particular, the Board noted that the sub-advisory fees are paid by the Adviser, and that the modifications to the sub-advisory fee rates would have no impact on the fees and expenses borne by shareholders of any Fund. The Board considered that the Amended American Century Agreement, the Amended MFS Agreement and the Amended Vontobel Agreement each reflected a reduction of the annual sub-advisory fee rate paid to the Sub-Adviser. In addition, under the Amended AllianceBernstein Agreement, the Amended Cohen & Steers Agreement, the Amended Eaton Vance Agreement, the Amended GSAM Agreement, and the Amended NIFA Agreement, certain breakpoints were being eliminated and the Sub-Adviser would be paid an annual percentage rate on assets under management that was lower than the Sub-Adviser currently received at the first tier of assets under management. The Board considered that the Amended TRP Agreement eliminated certain upper level breakpoints on assets over $1 billion, but noted that T. Rowe Price had agreed to a lower fee rate on all assets once assets under management reach $200 million (with the Large Growth Stock Fund currently benefitting since its assets were over $200 million). The Board considered the Adviser’s explanation for the changes, noting that the Funds have been experiencing outflows and are expected to continue to experience such outflows. In that context, removing an upper level breakpoint in favor of having a lower fee rate at the first tier provides a more favorable position for these Funds, since their assets are no longer expected to grow to reach the first breakpoint. The Board noted that the fee modifications were expected to result in a reduction in sub-advisory fees paid for each Fund at current assets under management. Following its evaluation, the Board concluded that, within the context of its full deliberations, the proposed sub-advisory fee schedule of each Fund was reasonable and supported the approval of the Amended Agreement.
Profitability. With regard to profitability, the Directors were presented with information about the effect of the proposed new sub-advisory fee schedule, if approved, on each Sub-Adviser and Adviser’s profitability in connection with its management of the Funds. The Directors considered all compensation flowing to each Sub-Adviser, as well as the Adviser and its affiliates, directly and indirectly. The Directors also noted that the Adviser had agreed to offer certain contractual advisory fee waivers to the Large Core Value Fund, the Large Cap Value Fund, the Mid Core Value Fund, the SMID Cap Value Fund, and the International Equity Fund through May 1, 2027, which would at least partially pass along the benefits of the sub-advisory fee reductions to Fund shareholders. The Directors also considered whether these levels of compensation and profitability under the Amended Agreement were reasonable and justified in light of the quality of all services to be rendered to each Fund by the applicable Sub-Adviser and its affiliates. Based on this evaluation, the Board concluded that, within the context of its full deliberations, the expected profitability of the Adviser and each applicable Sub-Adviser is reasonable and supported approval of each applicable Amended Agreement.

Economies of Scale. Management noted that the assets in each Fund were not expected to increase because the variable products in which the Funds are offered are no longer actively marketed and are slowly losing assets. The Directors concluded that the proposed modifications to each Fund’s sub-advisory fee rate schedule were reasonable in the context of Funds that were expected to lose further assets, but agreed to continue to monitor asset levels going forward to determine if restoration of breakpoints for certain Funds would be warranted again in the future.
Based on the Directors’ deliberations and their evaluation of the information described above, the Board, including all of the Independent Directors, unanimously approved each Amended Agreement. The Board concluded, in the exercise of its reasonable judgment, that each proposed sub-advisory fee rate schedule is fair and reasonable in relation to the services provided to each Fund and that approval of the applicable Amended Agreement would be in the best interests of each Fund and its shareholders. In its deliberations, the Board did not identify any particular factor (or conclusion with respect thereto) or single piece of information that was all-important, controlling or determinative of its decision and each Director may have attributed different weights to the various factors (and conclusions with respect thereto) and information.
                                                                                           *              *              *                         
On the basis of the information provided to it in advance of the Meetings and its evaluation of that information, as well as additional information provided by PMAM in response to the Board’s questions during the Meetings, the Board, including the Independent Directors, concluded that the terms of each Agreement were fair and reasonable, and that approval of each Agreement was in the best interests of each Fund and its shareholders.

Change in Independent Registered Public Accounting Firm 

At a meeting held on May 21, 2026, the Board of Directors (the “Board”) of Penn Series Funds, Inc.

KPMG’s audit reports on the Company’s financial statements as of and for the fiscal years ended December 31, 2024 and December 31, 2025 did not contain any adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal years ended December 31, 2024 and December 31, 2025 and the subsequent interim period through May 22, 2026, there were no: (i) disagreements with KPMG as described in Item 304(a)(1)(iv) on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to KPMG’s satisfaction would have caused KPMG to make reference to the subject matter of the disagreement in connection with its reports on the Company’s financial statements; or (ii) reportable events described in Item 304(a)(1)(v).

During the fiscal years ended December 31, 2024 and December 31, 2025 and during the subsequent interim period through May 22, 2026, neither the Company nor anyone on its behalf consulted with EY with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was the subject of a disagreement, as defined in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event, as described in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided KPMG with a copy of the foregoing disclosures and requested that KPMG furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not KPMG agrees with the above statements.
