REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of

Cleveland, Ohio

Opinion on the Financial Statements

We have audited the accompanying Statements of Net Assets Available for Benefits of the Parker Retirement Savings Plan (the “Plan”) as of December 31, 2025 and 2024, and the related Statement of Changes in Net Assets Available for Benefits for the year ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

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

Supplemental Information

The supplemental information in the accompanying Schedule of Assets (Held at End of Year) as of December 31, 2025 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement

Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

We have served as the Plan’s auditor since 2019.

1. Description of the Plan

General

The Parker Retirement Savings Plan ("the Plan") is sponsored by Parker Hannifin Corporation ("the Company"). The Plan is subject to Sections 401(a) and 401(k) of the Internal Revenue Code and the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. The following description of the Plan provides only general information and participants should refer to the Plan document or Summary Plan Description for a more complete description of the Plan’s provisions.

The Plan is a defined contribution plan available to U.S. domestic regular full-time and part-time non-union employees, and some union employees (if negotiated). Employees are eligible for participation in the Plan from their date of hire and are generally automatically enrolled in the Plan after completion of 30 days from the initial hire or rehire date. A separate Retirement Income Account ("RIA") also exists within the Plan. Some of the Company’s employees participate in the RIA in lieu of participating in a defined benefit plan. Similar to a defined benefit plan, participants do not make contributions to the RIA.

Participant Contributions

Participants may elect to contribute, through payroll deductions, not less than one percent nor more than 75 percent of their total compensation for a plan year, and may change such percentage upon request. Participants can elect to make before-tax, after-tax, and/or Roth contributions. Employee contributions and their associated Company matching contributions are primarily recorded in the period that payroll deferrals are deducted from participants. Contributions are subject to certain limitations.

Participants may designate one or more of several available funds within the Plan in which their contributions are to be invested, and may suspend their employee contributions at any time. Investment fund elections may be changed at any time. Employees have the flexibility to invest their RIA contributions in any investment fund offered by the Plan. The available investment funds are:

Common/Collective funds:

(a)Vanguard Institutional 500 Index Trust: A Collective Investment Trust ("CIT") invested in Institutional Select shares of the Vanguard 500 Index Fund which employs a "passive management" or indexing investment approach designed to track the performance of the S&P's 500 Index.

(b)Vanguard Institutional Extended Market Index Trust: A collective investment trust invested in Institutional Select shares of the Vanguard Institutional Extended Market Index Fund which employs an indexing investment approach designed to track the performance of the S&P's Completion Index.

(c)Vanguard Institutional Total Bond Market Index Trust: A collective investment trust invested in Institutional Select shares of the Vanguard Total Bond Market Index Fund which employs an indexing investment approach designed to track the performance of the Bloomberg U.S. Aggregate Float Adjusted Bond Index. The fund maintains a dollar-weighted average maturity consistent with that of the index.

(d)Vanguard Institutional Total International Stock Market Index Trust: A collective investment trust invested in Institutional Select shares of the Vanguard Total International Stock Index Fund which employs an indexing investment approach designed to track the performance of the FTSE Global All Cap ex US Index.

(e)State Street S&P 500 Index Trust: A CIT invested in Class X shares of the State Street S&P 500 Index Fund which employs a "passive management" or indexing investment approach designed to track the performance of the S&P's 500 Index.

(f)State Street U.S. Extended Market Index Trust: A CIT invested in Class X shares of the State Street U.S. Extended Market Index Fund which employs an indexing investment approach designed to track the performance of the Dow Jones U.S. Completion Total Stock Index.

(g)State Street U.S. Bond Index Trust: A CIT invested in Class X shares of the State Street U.S. Bond Index Fund which employs an indexing investment approach designed to track the performance of the Bloomberg U.S. Aggregate Bond Index. The fund maintains a dollar-weighted average maturity consistent with that of the index.

(h)State Street Global All Cap Equity Ex-U.S. Index Trust: A CIT invested in Class X shares of the State Street Global All Cap Equity Ex-U.S. Index Fund which employs an indexing investment approach designed to track the performance of the MSCI ACWI ex-U.S. IMI Index.

(i)Callan GlidePath Funds: Twelve common/collective funds which provide a target retirement date investment option to help participants diversify their assets. These funds invest in a diversified mix of asset classes and investment styles that become increasingly conservative over time using both actively and passively managed investments. These GlidePath funds allocate their assets across a broad range of underlying strategies, including global equities, broadly diversified fixed income and private real estate.

(j)Callan Small Cap Equity Fund: A common/collective fund which utilizes underlying funds that primarily invest in the equity securities of small and mid-capitalization companies across diversified economic sectors. This fund holds stocks issued by small and mid-sized companies domiciled primarily within the United States.

(k)Callan Diversified Real Assets Fund: The fund invests in underlying funds that allocate to asset classes expected to perform well in periods of rising or high inflation, including: infrastructure equity, natural resources equity, public real estate equity, private commercial real estate, and certain bonds and fixed income securities (such as inflation-indexed bonds, U.S. Treasury and agency bonds, and floating rate debt). The underlying funds used in this investment fund manage diversified portfolios of equity, fixed income and private commercial real estate.

(l)Callan Core Bond Fund: The fund invests in high quality bonds and other fixed-income securities, including U.S. government obligations, corporate bonds, mortgages and asset-backed securities.

(m)Callan International Equity Fund: The fund is a low-cost institutional CIT sponsored and maintained by Great Gray Trust Company, LLC as Trustee. The Fund is completely open-architecture and all underlying funds are managed by third party investment management firms. The Fund utilizes a broad range of underlying strategies managed by a diverse group of investment management organizations, each with a demonstrated expertise in their area of focus.

Equity securities funds:

(n)Parker Stock Fund: Invested primarily in common shares of the Company purchased on the open market. The Plan restricts participants from investing more than 50 percent of their account balance in the Parker Stock Fund.

(o)JPMorgan Analyst Large Cap Core Fund: A managed account with an objective of outperforming the S&P 500 Index by approximately two percent annualized over a market cycle; generally, a three to five-year time frame.

Other:

(p)BrokerageLink Account: This account allows participants to invest in a vast array of investments, including mutual funds, closed-end funds and real estate investment trusts offered from Fidelity Investments (Fidelity) and other companies.

Fully benefit-responsive contract fund:

(q)Contract Income Fund: A fully benefit-responsive investment contract fund invested primarily in high-quality fixed income investments, such as contracts issued by insurance companies and banks which provide a return guaranteed by the issuer, and debt securities such as notes and bonds issued by Federal agencies or mortgage and other asset-backed securities. Each of these investments typically provide a stable rate of return for a specific period. Refer to Note 6 for a further description of this fund.

Participant Accounts

The Plan utilizes the unit value method for allocating Plan earnings for all funds. Unit values are determined daily and exclude contributions receivable and benefits payable.

Parker-Hannifin Corporation Contributions

The Company generally contributes matching contributions to provide an amount equal to 100 percent of the first five percent of participants' pre-tax or Roth contributions. The Company does not match after-tax contributions. Participants may direct their Company matching funds to any investment fund within the Plan; the default option is the investment fund designated by the Company's Investment Committee. Matching contributions made in company stock are held in an Employee Stock Ownership Plan ("ESOP"). Similar to participant contributions, Company matching contributions may be changed at any time. Also, the Company makes an annual contribution to eligible participants' RIA accounts. A flat three percent annual contribution of eligible compensation, with some grandfathered participants receiving annual contributions calculated at a higher percent of eligible compensation. Under the RIA, no participant receives less than the flat three percent contribution.

Notes Receivable from Participants

Generally, the Plan has a loan provision which allows active participants to borrow a minimum of five hundred dollars up to the lesser of (a) 50 percent of their account balance or (b) fifty thousand dollars less the largest outstanding loan balance in the last 12 months. Participants may not borrow or withdraw any funds from their RIA account. Participant loans must be repaid over a period from one year to 4 1/2 years for general purpose loans and up to 10 years for residential loans. The applicable interest rate is equal to one percent above the published prime rate on the last day of the previous quarter. Due to various acquired plan transfers, some participant loans may have interest rates and repayment terms that differ from the Plan’s loan provisions. Notes receivable from participants are measured at their unpaid principal balance plus any accrued interest. Upon final liquidation of participant accounts, delinquent loans are reclassified as distributions.

2. Summary of Significant Accounting Policies

The financial statements of the Plan are prepared using the accrual method of accounting.

Investment Valuation

The Plan’s investments, except for the fully benefit-responsive investment contract, are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Refer to Note 7 for further discussion. The fully benefit-responsive investment contract is measured at contract value. Contract value is the amount participants normally would receive if they were to initiate permitted transactions under the terms of the Plan. Refer to Note 6 for further discussion.

Purchases and sales of securities are reflected on a trade-date basis. Dividend income is recorded on the ex-dividend date. Interest and other income are recorded as earned on the accrual basis.

Costs incidental to the purchase and sale of securities, such as brokerage commissions and stock transfer taxes, as well as investment advisory fees, are charged to the investment fund to which they relate and are netted against dividend and interest income. Certain administrative costs and expenses incurred by the Plan are paid out of the Plan’s assets, and the Company pays the remainder.

Risks and Uncertainties

Management believes the Plan’s investments are well diversified and do not create a significant concentration of interest rate, market, or credit risk. However, due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ accounts and the amount reported in the Statements of Net Assets Available for Benefits. Participants assume all risk in connection with any decrease in the fair value of any securities in all the investment funds. Although the annual rates of return for the contracts held in the Contract Income Fund are guaranteed by major insurance companies and banks, the Company does not make any

representations as to the financial capability of such companies or their ability to make payments under the contracts.

Other

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Benefit distributions are recorded when paid.

Subsequent Events

The Plan has evaluated subsequent events that have occurred through the date these financial statements were issued. Effective January 1, 2026, the former US employees of Curtis Instruments, Inc. became eligible to participate in the Plan. On January 24, 2026, investments of $89,642 were transferred from the Curtis Instruments, Inc. 401(k) Retirement Plan into the Plan. Additionally, the Plan assumed notes receivable from participants in the amount of $424. No subsequent events occurred that required adjustment to these financial statements.

3. Vesting, Withdrawals and Distributions

Contributions are always fully vested, except for the RIA contributions. Upon completion of three years of employment, RIA contributions become fully vested and may be withdrawn from the Plan only after termination. In general, participants’ accounts are disbursed from the Plan after termination of employment, but under certain circumstances, a portion of their accounts may be withdrawn while still actively employed, subject to certain limitations and restrictions.

After participants terminate employment for any reason, accounts may be distributed to the participant or to the participant’s designated beneficiary. Distribution from the Plan may be deferred until the age of 73, if the participant’s account exceeds five thousand dollars. Distributions are made either in a single payment, quarterly installments, or annuity purchase. Upon participant request, the Plan also allows the distribution of Parker common shares for amounts held in the Parker Stock Fund and Parker Stock Match Fund. The Plan provides that mandatory or involuntary lump-sum distributions in an amount less than one thousand dollars shall only be made in the form of an automatic rollover IRA. Dividends received by the Parker Stock Match Fund are either paid to the participants quarterly, annually, or reinvested quarterly, at the participants’ election.

4. Plan Transfers

On November 4, 2024, the Company announced it had completed the sale of its North America Composites and Fuel Containment Division to SK Capital Partners. The remaining Plan assets were transferred to the Axillon 401(k) Plan between March and August 2025.

On November 21, 2024, the Company completed the sale of its Total Filtration Services Division to the Flow Control Group. Plan assets related to this transaction were merged into the Flow Control Group 401(k) Plan on April 30, 2025.

The following represents the fair value of Plan investments at December 31, 2025 and 2024:


	2025		2024
Cash and cash equivalents	$	382	$	394

Equity securities	4,068,928		3,460,935
Common/Collective funds	5,249,674		4,638,894
Self-directed brokerage account	331,278		269,785

Total Plan investments at fair value	$	9,650,262	$	8,370,008

6. Contract Income Fund

The Contract Income Fund holds a portfolio of separate account and synthetic guaranteed investment contracts ("GICs") and other short-term securities. The fund is fully benefit-responsive and associated investments are reported at contract value. Contract value is the relevant measure for fully benefit-responsive investment contracts since it is the amount received by participants if they were to initiate permitted transactions under the terms of the Plan. Contract value represents contributions, plus earnings, less participant withdrawals and administrative expenses.

The following represents the disaggregation of contract value between types of investment contracts held by the Plan at December 31, 2025 and 2024:


	2025		2024
Short-term investment fund	$	18,655	$	14,140
Separate Account GICs	—		34,382
Fixed maturity synthetic GICs	74,699		71,819
Constant duration synthetic GICs	370,725		367,550
	$	464,079	$	487,891

Separate account GICs are investments in a segregated account of assets maintained by an insurance company for the benefit of the investors. The total return of the segregated account assets supports the separate account GICs’ return. The crediting rate on this product will reset periodically and it will have an interest rate of not less than zero percent.

Fixed maturity synthetic GICs generally consist of an asset or collection of assets and a benefit responsive, book value wrap contract purchased for the portfolio. The wrap contract provides book value accounting for the asset and assures that book value, benefit responsive payments will be made for participant directed withdrawals. The crediting rate of the contract is set at the start of the contract and typically resets every quarter. Generally, fixed maturity synthetics are held to maturity. The initial crediting rate is established based on the market interest rates at the time the initial asset is purchased, and it will have an interest crediting rate of not less than zero percent.

Constant duration synthetic GICs consist of a portfolio of securities and a benefit responsive, book value wrap contract purchased for the portfolio. The wrap contract amortizes gains and losses of the underlying securities over the portfolio duration, and assures that benefit responsive payments will be made at book value for participant directed withdrawals. The crediting rate on a constant duration synthetic GIC resets every quarter based on the book value of the contract, the market yield of the underlying assets, the market value of the underlying assets and the average duration of the underlying assets.

Withdrawals and transfers resulting from certain events, including employer-initiated events and changes in the qualification of the Plan may limit the ability of the fund to transact at book or contract value. These events may cause liquidation of all or a portion of a contract at market value. The Plan Administrator does not believe that the occurrence of any event which would limit the Plan’s ability to transact at book or contract value is probable.

7. Fair Value Measurements

The following is a summary of Plan investments measured at fair value on a recurring basis at December 31, 2025:


	Total		Quoted Prices In Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Cash and cash equivalents	$	382	$	382	$	—	$	—

Equity securities	4,068,928		4,068,928		—		—

Plan investments measured at net asset value (a)	5,249,674
Plan investments at fair value	$	9,650,262

The following is a summary of Plan investments measured at fair value on a recurring basis at December 31, 2024:


	Total		Quoted Prices In Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Cash and cash equivalents	$	394	$	394	$	—	$	—

Plan investments measured at net asset value (a)	4,638,894
Plan investments at fair value	$	8,370,008

(a) Plan investments measured at net asset value per share (or its equivalent) as a practical expedient to fair value have not been classified in the fair value hierarchy. These amounts are being presented in the tables above to permit reconciliation of the fair value hierarchy to the amounts presented in the Statement of Net Assets Available for Benefits.

Refer to Note 1 for fund information included in the fair value tables above. The following is a description of the valuation methodologies used to measure the fair values in the tables above. There have been no changes in the methodologies used to measure fair value at December 31, 2025 and 2024.

Cash and cash equivalents: Valued at cost, which approximates fair value.

Equity securities: Measured at fair value using quoted market prices.

Self-directed brokerage account: Valued at the closing price reported on the open market of the individual securities.

Plan investments measured at net asset value per share are excluded from the fair value hierarchy. These Plan investments can be redeemed daily, without restriction on the timing of the redemption. Redemption of the entire investment balance generally requires at least 30-days' notice. At December 31, 2025 and 2024, the Plan had no unfunded commitments related to these investments.

The primary investment objective of all investment funds is to obtain a maximum total return and capital appreciation in an amount that at least equals various market-based benchmarks.

8. Tax Status

The Internal Revenue Service has determined and informed the Company, by letter dated April 4, 2017, that the terms of the Plan and related trust, outlined in its determination filing on January 26, 2016, comply with applicable sections of the Internal Revenue Code ("IRC"). Since the filing, the Plan has been amended to provide for various administrative changes. The Plan Administrator believes that the Plan continues to be designed and operated in compliance with the applicable provisions of the IRC.

United States generally accepted accounting principles require plan management to evaluate uncertain tax positions taken by the Plan. The Plan Administrator has concluded that, as of December 31, 2025 and 2024, there were no uncertain tax positions taken or expected to be taken by the Plan. The Plan has not recognized any interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits in progress.

9. Plan Termination

Although it has not expressed any intent to do so, the Company, by action of its Board of Directors, without further approval by the shareholders, has the right to amend, modify, suspend, or terminate the Plan in its entirety, or for any subsidiary or operating location. No amendment, modification, suspension, or termination may permit assets held in trust by the trustee to be used for or diverted to purposes other than for the exclusive benefit of participants or their beneficiaries. If the Plan is terminated, all participant accounts would become fully vested.

10. Party-In-Interest

Certain Plan investments are managed by Fidelity. Fidelity Management Trust Company, a subsidiary of Fidelity, is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Callan LLC is the Plan's investment advisor. The Plan invests in several Callan sponsored funds which qualify as party-in-interest transactions.

The Plan also holds shares of Parker-Hannifin Corporation common stock. Investment activity related to these shares qualify as party-in-interest transactions.

11. Reconciliation of Financial Statements to Form 5500

The following is a reconciliation of Net Assets Available for Benefits per the financial statements at December 31, 2025 and 2024, to Form 5500:


	2025		2024
Net Assets Available for Benefits per Financial Statements	$	10,296,756	$	9,038,626
Adjustment from contract value to fair value for fully benefit-responsive GICs	(13,534)		(22,738)
Adjustment for deemed distributed participant loans(1)	(6,251)		(5,815)
Net Assets Available for Benefits per Form 5500	$	10,276,971	$	9,010,073

(1) Notes receivable from participants are reported on the Form 5500 as participant loans and are considered to be plan investments, while classified as notes receivable from participants in the Plan’s financial statements.

As a result of the adjustments above, Net income per Form 5500 is $1,292,230, a $8,768 increase from the net increase per the Statement of Changes in Net Assets Available for Benefits.
