Document

We have audited the accompanying statements of net assets available for benefits of RTX Savings Plan (the “Plan”) as of December 31, 2023 and 2022 and the related statement of changes in net assets available for benefits for the year ended December 31, 2023, including 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, 2023 and 2022, and the changes in net assets available for benefits for the year ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

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 of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our 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.

The supplemental schedule h, line 4i – schedule of assets (held at end of year) as of December 31, 2023 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental schedule 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 schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, 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 schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

The following description of the RTX Savings Plan (the Plan), formerly known as Raytheon Technologies Corporation Savings Plan, provides only general information. Participants should refer to the Plan documents for a complete description of the Plan's provisions, which can vary by participant location.

Prior to December 31, 2022, RTX Corporation (RTX, the Company, Employer, or the Plan Sponsor) maintained the United Technologies Corporation Employee Savings Plan (Legacy ESP), the United Technologies Corporation Represented Employee Savings Plan (Legacy RSP), and the Raytheon Savings and Investment Plan (Legacy RAYSIP). On December 31, 2022, the Legacy RSP and the Legacy RAYSIP merged into the Legacy ESP (the Plan Merger).

General. The Plan is a defined contribution savings plan sponsored by the Company. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Eligible participants of the Company are generally eligible to participate in the Plan immediately upon employment with RTX.

Contributions and Vesting. The percentages of eligible compensation that participants may elect to contribute, through payroll deductions, vary depending on the provisions of the Plan specific to a participant's location, but is generally any whole percentage up to 50%. Participants direct the investment of their contributions into various investment options offered by the Plan through the RTX Savings Plan Master Trust (Master Trust) (formerly Raytheon Technologies Corporation Savings Plan Master Trust). Participants may elect to make their contributions on a pre-tax, traditional after-tax, and/or Roth 401(k) basis.

Through the Master Trust, the Plan offers a stable value fund, a Government/Credit Bond Index Fund, four equity index funds (US large capitalization, US small company, international developed markets, international emerging markets), two multi-asset class funds (inflation sensitive assets and multi-market risk parity), two employer stock funds (RTX Stock Fund and RTX ESOP Fund, which is available only for the Company matching contributions made through the leveraged Employee Stock Ownership Plan (ESOP) described below), a suite of thirteen target retirement funds, and a brokerage window that offers participants the ability to invest in mutual funds and exchange traded products. The Plan also offers the Lifetime Income Strategy (LIS) investment option. The LIS includes an insurance component and is intended to provide participants with a steady stream of secure retirement income. The LIS is the Plan's qualified default investment option. In addition, the Master Trust includes a money market fund that is primarily used for transitioning or merging plans.

Participant contributions, plus actual earnings (losses) thereon, are fully vested at all times under the Plan. Certain new participants in the Plan are automatically enrolled at a pre-tax deferral rate of 6% of eligible compensation, per the provisions of the Plan. Generally, the contribution rate automatically increases by 1% each year thereafter until it reaches 10%. For certain employees, automatic enrollment and automatic contribution rate increases vary, based on the provisions of the Plan document. Participants may opt out of automatic enrollment at any time. Participants may opt in or out of automatic contribution rate increases at any time.

Generally, RTX matches 100% of the first 3%, and 33.3% thereafter, up to 6%, of eligible compensation that a participant contributes each pay period. Company matching contributions are made in stock and/or cash, and are invested based on the investment allocation elected by each participant. Company matching contributions, plus actual earnings thereon, become fully vested after two years of service. Participants should refer to the Plan documents for a complete description of the Plan's matching provisions, which can vary by participant location.

The Plan provides a Company retirement contribution, an automatic non-elective Company contribution, to certain eligible employees hired after December 31, 2009. Contributions as a percentage of the participant's eligible compensation, as defined in the Plan, will equal 3% - 9% based upon employee age as of December 31 of the current Plan year. Such contributions will be made regardless of an employee's election to participate in the Plan. Company retirement contributions are generally subject to the same terms and conditions applicable to Company matching contributions, provided, however, that the Company retirement contributions shall not be available for loans or hardship distributions. Participants should refer to the Plan

For certain legacy pension plan participants, RTX makes retirement contributions to the Plan account instead of adding pay credits to the cash balance account in the RTX Consolidated Pension Plan. The retirement contribution percentage is based upon the age of the participant as of December 31 of the current Plan year.

RTX has established a leveraged ESOP to fund certain Company matching contributions to the Plan. The ESOP is primarily invested in RTX Common Stock. Shares allocated to a participant's ESOP account may be re-allocated to other Plan investments without restriction, provided the participant has satisfied the Plan's vesting requirements.

Participants may also participate in the Student Loan Repayment Contribution (SLRC) program in the Plan. An SLRC participant who makes qualified student loan repayments may receive the SLRC employer contribution in an amount equal to the Company match the participant would otherwise be eligible to receive, reduced for any other Company matching contributions made during the year. Such contributions would be made in the following year.

Participant Accounts. Each participant account is credited with (a) the participant contributions, (b) Company contributions, and (c) Plan earnings and losses, or an allocation of Plan earnings (losses), reduced by expense charges/allocations. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Forfeited balances of terminated participants' non-vested Company contribution amounts are used to reduce future RTX contributions and/or to pay Plan expenses. For the year ended December 31, 2023, amounts forfeited from non-vested accounts for the Plan totaled approximately $8.6 million, of which $6.3 million was used to fund RTX's contributions. As of December 31, 2023 and 2022, the balance of forfeited non-vested accounts for the Plan was $6.6 million and $4.2 million, respectively.

Voting Rights. Common Stock held in the RTX Stock Fund and/or RTX ESOP Fund are voted by the Trustee at RTX shareowner meetings in accordance with the confidential instructions of the participants whose accounts are invested in these funds. All shares of Company stock in the RTX Stock Fund or in participants' ESOP accounts, for which the Trustee receives voting instructions from participants to whose accounts the shares are allocated, are voted in accordance with those instructions. All Company stock in the RTX Stock Fund for which the Trustee does not receive timely voting instructions are voted by the Trustee in accordance with the timely instructions it receives with respect to a plurality of the shares in the RTX Stock Fund. All Company stock in the RTX ESOP Fund that has been allocated to participants' ESOP accounts, but for which the Trustee does not receive timely voting instructions, and all shares in the unallocated ESOP account, are voted by the Trustee in accordance with the timely instructions it receives with respect to a plurality of the shares that are allocated to participants' ESOP accounts.

Notes Receivable from Participants. Under the terms of the Plan, certain participants are allowed to borrow up to the lesser of 50 percent of their vested account balances (excluding company retirement contributions) or $50,000, less the participant's highest outstanding loan balance over the previous 12 months. Minimum loan amounts start at $1,000, and participants must generally repay their loan within five years, except if the loan is used to acquire the participant's primary residence. Participants may have two loans outstanding at a time. Loans are secured by the balance in the participant's account, and bear interest at the prime rate published in the Wall Street Journal plus 1%. Interest rates generally remain fixed for the term of the loan. At December 31, 2023 and 2022, the interest rates on the outstanding loans ranged from approximately 3.24% to 10.5%, and approximately 3.25% to 10.5%, respectively. Principal and interest are paid ratably through payroll deductions by active participants or through direct payment by inactive participants. The Plan's balance of Notes receivable from participants as of December 31, 2023 and 2022 includes remaining participant balances from certain other plans previously transferred into the Plan.

Payment of Benefits. Generally, upon termination, benefits may be left in the Plan or paid in a lump sum to a terminating participant. A participant terminating due to retirement, who is invested in funds other than the LIS, may elect to receive benefits in installments over two to twenty years. At the participant's election, if applicable, the portion of a lump sum distribution attributable to an investment in the RTX Stock Fund and RTX ESOP Fund may be paid in shares of RTX Common Stock instead of cash. Distributions in RTX Common Stock for the year ended December 31, 2023 for the Plan were approximately $90 million at fair value as of the respective transaction date.

Retiring participants invested in the LIS can receive a lifetime guaranteed annual income benefit, which is calculated based on participants’ accumulated balances at retirement in the Secure Income Portfolio component of the LIS. The annual income benefit is secured with insurance contracts and is guaranteed for life, even if the participant's balance in the LIS becomes exhausted during retirement. Payment can be taken monthly or as-needed, however, participants cannot carry forward unused

Master Trust. The Plan's assets are kept in the Master Trust maintained by the Trustee. Under the Master Trust agreement, the assets of certain employee savings plans of RTX are combined. Participating plans purchase units of participation in the underlying investment funds based on their contribution to such funds and the unit value of the applicable investment fund at the end of the trading day in which a transaction occurs. The unit value of each fund is determined at the close of each day by dividing the sum of uninvested cash, accrued income and expenses, and the current value of investments, by the total number of outstanding units in such funds. Income or losses from the funds' investments, other than the RTX Stock Fund and RTX ESOP Fund for certain participants, increase or decrease the participating plans' unit values. RTX Stock Fund and RTX ESOP Fund dividends for certain participants increase the Plan's units in each fund. Distributions to participants reduce the number of participation units held by the participating plans. See Note 4 for additional information.

Fully Benefit-Responsive Investment Contracts. The Master Trust invests in a stable value fund that invests in synthetic guaranteed investment contracts (GICs) with financial institutions. Historically, the Master Trust also invested in managed separate account GICs with financial institutions, but transitioned to only synthetic GIC investments during 2023. Synthetic GICs provide for a variable crediting rate which resets quarterly. Managed separate account GICs are investment contracts invested in insurance company separate accounts established for the sole benefit of RTX stable value fund participants. The assets are wrapped by an insurance company. The Plan participates in the underlying experience of the separate account via future periodic rate resets, which once set, are guaranteed by the insurance company. In each case, the wrap contracts provide assurances that future adjustments to the crediting rate cannot result in a crediting rate of less than zero. As fully benefit-responsive investment contracts, the stable value fund investments are stated at contract value (the amount available to pay benefits). Contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan and includes contributions plus earnings, less Plan withdrawals and expenses. There are no reserves against contract value for credit risk. See Notes 3 and 5 for additional information.

Investment Valuation and Income Recognition. The fair value of a financial instrument is generally determined as the amount that could reasonably be expected to be realized from an orderly disposition of securities and other financial instruments over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the valuation in a current sale and may not reflect the actual market price. It is the amount 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.

Short-term investments represent cash and investments held by the Master Trust in commingled institutional funds and are valued at the reported net asset values (NAV) per unit as of the valuation date. The commingled institutional funds classified as short-term investments, known as short term investment funds, transact daily without restriction in a manner similar to money market funds with an objective of maintaining a constant $1.00 NAV through investment in high-quality securities with short durations. Although not traded on an active market, the NAVs of the short term investment funds are observable. Cash is valued at the amounts deposited in the account, plus accrued interest.

Commingled funds represent investments held in institutional funds and are valued at the NAV as a practical expedient as of the valuation date. The commingled funds are made up of a variety of index funds. The underlying holdings of the commingled funds are primarily marketable equity and fixed income securities. As of December 31, 2023 and 2022, there were no restrictions in place related to either participant or plan sponsor-directed redemption of these commingled funds. If the Plan were to initiate a trade of significant size, either into or out of the commingled funds, the investment adviser of the commingled fund reserves the right to request a reasonable period of notice to ensure that trading of securities will be implemented in an orderly business manner.

The Plan offers the LIS as an investment option, which includes an insurance component for participants who want to receive a steady stream of secure retirement income. The LIS consists of six sub-funds: US Equity (large and small capitalization), International Equity (developed and emerging markets and global REITs), Real Assets (commodities and natural resources), Core Bond (US government/credit and US TIPS), Cash (1-3 year US Treasury securities), and Secure Income Portfolio. Alliance Bernstein allocates each participant’s holding in the LIS among these six sub-funds using pre-determined glide paths based on the participant’s years until target retirement age and selected level of secure retirement income. The first five sub-funds are comprised of underlying investments of the Master Trust commingled funds and managed separate accounts. The Secure Income Portfolio represents a collective trust fund with an investment objective of long-term growth of capital and includes an insurance component that provides the guaranteed lifetime retirement income. As of December 31, 2023 and 2022, there were no restrictions in place related to either participant or plan sponsor-directed redemption of these funds unless certain

criteria are met. If the Plan were to initiate a trade of significant size, either into or out of the commingled funds, the investment adviser reserves the right to request a reasonable period of notice to ensure that trading of securities will be implemented in an orderly business manner.

The Master Trust invests in managed separate accounts established for the sole benefit of RTX participants. The investment valuation policy of these managed separate accounts is to value investments at fair value. Investments and other portfolio instruments are generally valued using a market approach. Common stock, preferred stock, and interest in real estate investment trusts are stated at fair value, determined using the closing sales prices for the investments as of the valuation date. Fixed income investments are valued on the basis of valuations furnished by Trustee-approved independent pricing services. These services determine valuations for normal institutional-size trading units of such securities using models or matrix pricing, which incorporates yield and/or price with respect to bonds that are considered comparable in characteristics such as rating, interest rate, and maturity date, and quotations from bond dealers to determine current value. If these valuations are deemed to be either not reliable or not readily available, the fair value will be determined in good faith by the Trustee.

Shares held in mutual funds and exchange traded funds through the self-directed brokerage window are valued at the published NAV as of the last business day of each period presented. Certain limitations are placed on balances and direct transfers into the mutual fund brokerage window. Participants may not take a distribution or a loan directly from the mutual fund brokerage window, however, if available, they may be initiated through the other investment options.

The RTX Stock Fund invests only in RTX common stock. The value of the units credited to participants' RTX Stock Fund accounts tracks the value of RTX common stock, and this Fund holds certain highly liquid short-term investments, which provide readily available cash to fund participants’ distributions, loans, and investment exchanges. At December 31, 2023 and 2022, RTX Stock Fund was stated at fair value determined using the closing sales price of RTX common stock as of the valuation date.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is accrued when earned. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) on the fair value of investments includes gains and losses on investments bought and sold as well as held during the year.

Plan Expenses. Certain Plan administrative expenses were paid directly by the Company in 2023. Master Trust specific expenses are charged at the Master Trust level. All other administrative, Trustee, legal, investment management, recordkeeper, and other expenses were paid from Plan assets or certain participant accounts during 2023, and are presented on the statement of changes in net assets available for benefits, either in Administrative expenses or Plan interest in net increase in net assets of Master Trust.

Use of Estimates. The preparation of the Plan's financial statements, in conformity with accounting principles generally accepted in the United States of America (US GAAP), requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the dates of the financial statements, and changes therein during the reporting period and, when applicable, disclosures of contingent assets and liabilities at the dates of the financial statements. Actual results could differ from those estimates.

Risks and Uncertainties. Through the Master Trust, the Plan provides for various investment options in any combination of stocks, bonds, mutual funds, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risk. These risks can be adversely impacted by shifts in the market's perception of the issuers, changes in interest rates, and global economic conditions. Due to the level of risk associated with certain investment securities, and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits. See Note 6 for discussion of risks and uncertainties related to derivatives.

only synthetic GIC investments during 2023. Under these contracts, each insurance company guarantees repayment in full of the principal amount plus interest credited at a fixed rate for a specified period. Interest is credited to each contract based on an interest rate set each quarter by the individual insurance companies. This rate, which differs among contracts, takes into account any difference between prior quarter credited interest and the actual amount of investment earnings allocable to the contract in accordance with the established allocation procedures of the insurance company. The crediting rate is primarily based on the current yield-to-maturity of the covered investments, plus or minus amortization of the difference between the market value and contract value of the covered investments over the duration of the covered investments at the time of computation. There are no reserves against contract value for credit risk.

Certain events could limit the ability of the Plan to transact at contract value with the issuer. Such events include the following: (i) certain amendments to the Plan documents that adversely impact the stable value fund; (ii) introduction of an investment option that competes with the stable value fund; (iii) certain Plan sponsor events (e.g. a significant divestiture) that cause a significant withdrawal from the Plan; (iv) the failure of the trust to qualify for exemption from federal income taxes; or, (v) material breach of contract provisions. RTX does not believe that the occurrence of any such event, which would limit the Plan's ability to transact at no less than contract value with participants, is probable. Certain events enable issuers to terminate their contracts with RTX and settle at an amount other than contract value. Under each contract, the Plan has the option to address and cure any such event within a specified period of time. RTX does not believe that the occurrence of any such event is probable.

RTX has entered into a Master Trust agreement with the Trustee. The Plan purchases units of participation in the investment options based on its contribution to such options, in addition to income or loss the investment options may earn or sustain, less distributions made to the plan participants and plan expenses.

The Plan’s interest in the Master Trust represented 100% of the Master Trust’s net assets at December 31, 2023 and 2022. Although the Plan is the only participating plan in the Master Trust as of December 31, 2023, the Company intends to keep the Master Trust for potential future acquired plans and file a Form 5500 for the Master Trust.

The Fair Value Measurements and Disclosure Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) establishes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. Classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. This hierarchy prioritizes the inputs into three broad levels:

The following tables provide the investments in the Master Trust carried at fair value measured on a recurring basis as of December 31, 2023 and 2022:

The investment managers retained by RTX have discretion to invest Master Trust assets in derivative financial instruments to manage risk and achieve trading and cost efficiency when the underlying security may not be accessible at a reasonable transaction cost or may be impractical to invest in from an administrative perspective. These derivatives consist of interest rate futures and swaps contracts contained in assets wrapped by insurance companies and reported at contract value within the stable value fund and index futures contracts held within the managed separate accounts.

Futures Contracts. The Master Trust uses fixed income and equity index and interest rate futures contracts to manage exposure to the market. Buying futures tends to increase the Master Trust's exposure to the underlying instrument. Selling futures tends to decrease the Master Trust's exposure to the underlying instrument held or offset the fair value of other fund investments. Futures contracts are valued at the last settlement price at the end of each day on the exchange upon which they are traded.

Upon entering into a futures contract, the Master Trust is required to deposit either in cash or securities an amount (initial margin) equal to a certain percentage of the nominal value of the contract. Pursuant to the futures contract, the Master Trust agrees to receive from or pay to the Futures Commission Merchant (FCM) an amount of cash equal to the daily fluctuation in

the value of the futures contract. Such receipts or payments are known as "variation margin" which are generally settled daily and are included in the net appreciation (depreciation) on fair value of investments. The Master Trust will record a variation margin receivable or payable in the Master Trust net assets for variation margins which have not yet been received or paid at the end of the year.

Futures contracts involve, to varying degrees, credit and market risks. The Master Trust enters into futures contracts on exchanges where the exchange acts as the counterparty to the transaction. Thus, credit risk on such transactions is limited to the failure of the exchange. Futures orders are executed on behalf of the Master Trust by FCM firms which determine margin requirements consistent with industry standards and the various rules and regulations of the exchanges on which trades occur. Initial and maintenance margin rates used in determining margin requirements may vary, but are established at levels no lower than those prescribed by U.S. Commodity Futures Trading Commission regulations. FCM relationships and operations (including treatment of customer capital and capital requirements) are overseen by both the investment managers and RTX. The daily settlement on the futures contracts serves to greatly reduce credit risk. Losses in value may arise from changes in the value of the underlying instruments or if there is an illiquid secondary market for the contracts. In addition, there is the risk that there may not be an exact correlation between a futures contract and the underlying index or security.

The Trustee executed a series of promissory notes (ESOP debt), which are internal financing arrangements designed to align the value of shares released from the reserve account, as described below, with plan matching contribution obligations. (See Note 8 for details on the portions of ESOP debt currently outstanding).

Shares of Common Stock are allocated to participant accounts of the Plan as certain participants earn RTX's matching contributions. Shares of Common Stock are released for allocation to participants as principal and interest payments are made on the ESOP debt. Cash dividends on Common Stock shares held by the ESOP and additional contributions from RTX are used to repay ESOP debt principal and interest. ESOP debt may be pre-paid or re-amortized to either increase or decrease the number of shares released so that the value of released shares equals the value of the plan benefit. The Company may also, at its option, contribute additional Common Stock or cash to the ESOP. RTX has provided certain guarantees related to the matching contribution formula and certain other commitments in connection with the ESOP debt. For the year ended December 31, 2023, certain participants were credited with matching contributions in Common Stock of approximately $261 million representing approximately 2,909,000 shares. Additionally, in lieu of receiving cash, participants' dividends are paid by allocating additional shares to participant accounts. Participants may elect to receive cash dividends. During 2023, participants earned dividends of approximately $56 million representing approximately 630,000 shares of Common Stock.

The RTX ESOP Fund's investment in RTX Common Stock shares at December 31, 2023 and 2022 is as follows:


	2023				2022
(thousands of dollars, except shares)	Allocated		Total		Allocated		Total
Number of Shares	24,313,167		26,232,044		24,434,891		29,341,164
Market Value	$	2,045,710	$	2,207,164	$	2,465,969	$	2,961,110

The net assets available for benefits in the RTX ESOP Fund related to RTX Common Stock at December 31, 2023 and 2022 include unrealized appreciation of approximately $2.0 billion and $2.7 billion, of which approximately $0.1 billion and $0.5 billion relates to unallocated shares, respectively.

Company matching contributions made through the ESOP are automatically invested in the same manner as participants' elective contributions, to provide an element of auto-diversification to reduce unintended concentration of participants' balances in Company stock. Participants may make an election to continue to receive their Company matching contributions in the ESOP.

The Plan invests in the RTX Stock Fund (the Fund), which is comprised of a short-term investment fund component and shares of common stock of RTX. The unit values of the Fund are recorded and maintained by the Trustee. The total value of the Plan's interest in the Fund was approximately $3.4 billion and $4.2 billion at December 31, 2023 and 2022, respectively. During the year ended December 31, 2023, the Plan purchased units of the Fund of approximately $389 million including dividends and interest of approximately $92 million, sold units of the Fund of approximately $546 million, and had net depreciation on the Fund of approximately $661 million.

The Plan invests in the ESOP, which is comprised of a short-term investment fund component and shares of common stock of RTX. The total value of the Plan's interest in the ESOP was approximately $2.2 billion and $3.0 billion at December 31, 2023 and 2022, respectively (see Notes 1, 7, and 8). In connection with the note payable financing (see Note 8), the Plan has an ESOP receivable of approximately $28 million and $15 million from RTX as of December 31, 2023 and 2022, respectively.

In addition, certain of the investment options are managed by State Street Global Advisors Trust Company, an affiliate of the Trustee. Transactions in such investments qualify as exempt party-in-interest transactions. Notes receivable from participants transactions also qualify as party-in-interest transactions.

Although it has not expressed any intent to do so, RTX has the right under the Plan to discontinue its contributions at any time, and to terminate the Plan, subject to the provisions of ERISA and certain Plan provisions that limit this right when certain ESOP loans remain outstanding. In the event of Plan termination, participants will become 100 percent vested in their accounts.

The Internal Revenue Service (IRS) determined and informed the Company by letter dated October 28, 2016 that the Plan is designed in accordance with applicable sections of the Internal Revenue Code. The Plan has been amended since receiving the determination letter. The Company believes that the current design and operation of the Plan are consistent with preservation of the qualification of the Plan and exemption of the Trust in the context of applicable IRS procedures.

US GAAP requires plan management to evaluate tax positions taken by the Plan and recognize a tax liability if the organization has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Company believes it is no longer subject to income tax examinations for years prior to 2020.
