Report of Independent Registered Public Accounting Firm

To the Administrator and Plan Participants of AstraZeneca Savings and Security Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of AstraZeneca Savings and Security Plan (the “Plan”) as of December 31, 2022 and 2021 and the related statement of changes in net assets available for benefits for the year ended December 31, 2022, 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, 2022 and 2021, and the changes in net assets available for benefits for the year ended December 31, 2022 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 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.

Supplemental Information

The supplemental schedule of assets (held at end of year) as of December 31, 2022 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.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

__________

General:

The following description of the AstraZeneca Savings and Security Plan (the “Plan”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions. The Plan, formerly known as the Zeneca Deferred Compensation Plan, was established on April 1, 1958, and was designed to provide a systematic means of saving and investing for the future.

Effective July 1, 2000, the Zeneca Deferred Compensation Plan was amended and restated as the Plan sponsorship transferred from Zeneca Inc. to AstraZeneca Pharmaceuticals LP (the “Company”). Regular full-time and part-time employees of the Company are immediately eligible to participate in the Plan. The Company is an indirect wholly owned subsidiary of AstraZeneca PLC. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

The Plan is intended as a plan described in Section 404(c) of ERISA and Section 2550.404c-1 of Title 29 of the Code of Federal Regulations. Because the Plan allowed participants to invest both before-tax and after-tax contributions in AstraZeneca PLC American Depositary Receipts (“ADRs”), the Plan and the stock offered thereunder are registered under the Securities Act of 1933 (the “Act”). Participants have not been able to make new investments in, or transfer funds to the ADRs on or after December 15, 2015.

The AstraZeneca Investment Committee is the Plan’s named fiduciary for investment and certain administrative duties, and the AstraZeneca Administration Committee is the Plan’s named fiduciary for claims administration and certain other duties. Both committees are appointed by and subject to review by the AstraZeneca North America HR Sub-Committee.

Administrative Expenses:

Some costs and expenses incident to the administration of the Plan and the management of the trust, including the compensation of the trustee, are paid by the Company. Brokerage charges and fees incurred in connection with the purchase and sale of securities are included as an element of the cost of securities purchased or as a reduction in the proceeds of securities sold. Investment advisory fees are paid by the Company. Administrative expenses included in the statement of changes in net assets available for benefits relate to participant distribution mailings and short-term trading fees applicable to certain investment options. These amounts are paid by the Plan, as a reduction from the participants’ account.

Contributions:

Participants can make before-tax or after-tax (including ROTH) contributions of up to 50% of annual eligible compensation. The maximum amount of the Company match is one dollar for each dollar of the first 6% of eligible compensation that a participant contributes to the Plan. Participants age 50 and over are eligible to contribute additional before-tax and ROTH contributions (“catch-up contributions”) above the annual Internal Revenue Service ("IRS") limitations up to $6,500 in 2022. The contribution limit for participants is $20,500 and the limitation on benefits and contributions under Section 415(c)(1)(A) of the Internal Revenue Code is $61,000 in 2022.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

__________

Certain employees of the Company are eligible to receive “AZ Retirement Company Contributions.” A participant’s employer contribution is equal to a specified percentage of a participant’s eligible compensation for the Plan year, based on a participant’s points. Participant’s points are calculated as the aggregate age and service credits allocated to a participant for a plan year determined as of December 31 of the prior plan year. A participant shall receive one point for each year of attained age and one point for each completed year of points service. A participant shall also receive one point for full months of attained age and completed service that aggregate 12. During 2022, the specific employer contribution percentage was determined by the basis of the participant’s points for the Plan year as set forth in the following chart:

The amount of contributions is subject to the limitations imposed by the Internal Revenue Code (“IRC”). Both employee and Company contributions are allocated to each participant account. Participants direct the investment of their employee and Company contributions into the various investment options offered by the Plan.

Participant Accounts:

Each participant’s account is adjusted periodically to reflect his or her allocated portion of participant and Company contributions and investment earnings or losses. Investment income or losses allocated to each participant’s account are based on the portion of income and expenses and gains and losses of each investment in which the assets represented by the participant’s account are invested.

Vesting:

Participants are immediately vested in their contributions and all Company matching contributions, plus actual earnings thereon. A participant who is credited with at least one hour of service on or after January 1, 2007 becomes fully vested in his or her AZ Retirement Company Contributions after the completion of three years of service. If a participant is involuntarily terminated as a result of a Company restructuring, layoff or job elimination, their account will become fully (100%) vested if they would have otherwise become fully vested under the terms of the Plan no later than the six month anniversary of the date of their involuntary termination.

__________

Participant Loans:

The Plan allows plan loans pursuant to Section 408(b)(1) of ERISA and the regulations thereunder. The maximum loan amount is the lesser of 50% of a participant’s account balance or $50,000, excluding any amounts in the AZ Retirement Company Contributions and reduced by the participant’s highest outstanding plan loan balance over the previous 12 months. The minimum loan amount is $1,000 and the maximum is two loans outstanding at any time for any eligible borrower. Loans must generally be repaid over a period of up to five years, except for loans to purchase a principal residence which may be repaid over a period of up to 10 years. Interest rates are based on the “prime rate” published in the Wall Street Journal on the first calendar day of the month in which the loan is taken and remains fixed over the life of the loan. The principal amount and interest on a loan shall be repaid by level payroll deductions during each payroll period in which the loan is outstanding. As of December 31, 2022, the interest rates on the participant loans range from 3.25% to 6.5%. The AZ Retirement Company Contributions are not available for loans.

Payment of Benefits:

In the case of death, disability, termination, or retirement, a participant or, if applicable, the participant’s beneficiary, may receive a distribution of the vested portion of his or her accounts in a lump-sum amount or in installments (excluding termination). In addition, a participant may elect to withdraw all or part of his or her account in special circumstances, as defined by the Plan.

Forfeited Accounts:

If participants terminate employment prior to becoming fully vested in their AZ Retirement Company Contributions, then those contributions will be forfeited and used to reduce future employer company contributions to the Plan for the remaining participants. At December 31, 2022 and 2021, forfeited nonvested accounts totaled $878 and $22,063 respectively. Forfeitures used to reduce employer company contributions were $135,162 for the year ended December 31, 2022.

The significant accounting policies employed in the preparation of the accompanying financial statements are as follows:

Basis of Accounting:

The financial statements of the Plan are prepared in compliance with the Department of Labor’s (“DOL”) Rules and Regulations for Reporting and Disclosure under ERISA and under the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Investment Valuation and Income Recognition:

Investments are reported at fair value (except for the fully benefit-responsive investment contracts, which are reported at contract 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. The Plan’s Investment Committee determines the Plan’s valuation policies utilizing information provided by the investment advisers, custodians and insurance companies. See note 4 for discussion of fair value measurements.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

__________

Investment Valuation and Income Recognition, continued:

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are record on the ex-dividend date. Net appreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Notes Receivable from Participants:

Notes receivable from participants (loans) are measured at their unpaid principal balance plus any accrued but unpaid interest. Defaulted participant loans are reclassified as benefits paid based upon the terms of the Plan document.

Payment of Benefits:

Benefit payments are recorded when paid.

Use of Estimates:

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The Plan invests in a portfolio of fully benefit-responsive guaranteed investment contracts (“GICs”) issued by insurance companies that is required to be reported at contract value. PFM Asset Management LLC served as the investment manager for the portfolio through December 15, 2022 and was replaced by Invesco Advisers, Inc., with oversight from the AstraZeneca Investment Committee. The portfolio is credited with interest on the GICs and debited for participant withdrawals.

Participants may direct the withdrawal or transfer of all or a portion of their investment. Participants cannot transfer their balance to a competing investment option without the amount of such transfer first being directed to one of the Plan’s other investment options and held thereunder for at least 90 days.

The Plan holds two types of investment contracts: traditional GICs and synthetic wraps. A traditional GIC is an investment contract issued by an insurance company or bank that provides for the payment of a specified rate of interest to the Plan and for the repayment of principal when the contract matures. A synthetic wrap unbundles the investment and insurance components of a traditional GIC. The plan invests in and retains ownership of a pool of fixed income securities (e.g., government securities, pooled separate accounts, private and public mortgage-backed securities, other asset-backed securities and investment grade corporate obligations, etc.).

These securities are “wrapped” by a synthetic investment contract issued by a bank or insurance company that insures that participant-initiated withdrawals from the synthetic investment contract will be paid at contract value. The gain or loss on the underlying investments is recognized over time by adjusting the interest rate credited to the Plan under the synthetic wrap.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

The following table lists the investment contract values as of December 31, 2022 and 2021:

Fully benefit-responsive investment contracts guarantee that (1) the crediting rate provided under the contract will not fall below zero and (2) participant-initiated withdrawals from the fund (i.e., withdrawals as a result of death, disability, retirement, termination of employment, hardship withdrawal, loan, and transfers to a non-competing fund) will be covered at contract value.

Certain events might limit the ability of the Plan to transact at contract value with the issuer. In certain circumstances, the amount withdrawn from the contract would be payable at fair value rather than at contract value. These events may include, but are not limited to, the redemption of all or a portion of the interests in the Fund at the direction of the Plan Sponsor (including partial termination of the Plan), withdrawals due to the removal of a specifically identifiable group of employees from coverage under the Plan (such as a group layoff or early retirement incentive program), the closing or sale of a subsidiary or unit, the bankruptcy or insolvency of the Plan Sponsor, or if the terms of a successor plan (in the event of the spin-off or sale of a division) do not meet the contract issuer’s underwriting criteria for issuance of a clone contract. The events described above that could result in the payment of benefits at fair value rather than at contract value are not currently probable of occurring.

In addition, certain events allow the issuer to terminate the contract with the Plan and settle at an amount different from contract value. Examples of such events include the Plan’s loss of its qualified status, material breaches of contractual obligations that are not cured, delivery of any communication to plan participants to influence a participant not to invest in the Stable Value option, the issuer’s determination that the agreement constitutes a nonexempt prohibited transaction as defined under ERISA, a material and adverse change to the provisions of the Plan, or termination of the Plan. If one of these events were to occur, the contract issuer could terminate the contract at the market value of the underlying investments (or in the case of a traditional GIC, at the hypothetical market value based upon a contractual formula).

The Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurement, establishes a framework for measuring fair value and enhances disclosures about fair value measurements. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820 are described as follows:

Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

Level 2: Inputs to the valuation methodology include:

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of relevant observable inputs and minimize the use of unobservable inputs.

The following is a description of the valuation methodologies used for assets measured at fair value:

Common stock: Funds are invested in the common stock of AstraZeneca PLC (“AZ Common Stock”). The fair value is a quoted price in an active market.

Mutual funds: Valued at fair value of shares held by the Plan at year end. The fair value is a quoted price in an active market. The net asset value (“NAV”) is based upon the assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.

Commingled funds: Valued at the NAV of shares held by the Plan at year end. The NAVs, provided by external investment managers as a practical expedient, are based on quoted prices for the fund’s underlying securities (some of which are marketable), estimates, appraisals, assumptions, and methods that are reviewed by management. This investment category has no unfunded commitments and there are no redemption restrictions.

Collective trusts: Valued at the NAV of shares held by the Plan at year end. The NAVs, provided by external investment managers as a practical expedient, are based on quoted prices for the funds’ underlying securities (some of which are marketable), estimates, appraisals, assumptions, and methods that are reviewed by management. This investment category has no unfunded commitments and there are no redemption restrictions.

Money market funds: Valued at fair value of shares held by the Plan at year end. The fair value is a quoted price in an active market.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

__________

The following table lists the fair values of investments as of December 31, 2022 and 2021:

(a) In accordance with Subtopic 820-10, collective trusts and commingled funds that were measured at net asset value per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the line items presented in the statement of net assets available for benefits.

The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another.

For the years ended December 31, 2022 and 2021, there were no transfers in or out of level 3 as there were no level 3 investments noted.

ASTRAZENECA SAVINGS AND SECURITY PLAN

Notes to Financial Statements

__________

The IRS has determined and informed the Company by a letter dated February 8, 2018, that the Plan and related trust are designed in accordance with applicable sections of the IRC. Although the Plan has been amended since receiving the determination letter, the Plan administrator and the Plan’s tax counsel believe that the Plan is designed and restated, and is currently being operated, in compliance with the applicable requirements of the IRC and, therefore, believe that the Plan is qualified, and the related trust is tax-exempt.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the plan and recognize a tax liability (or asset) if the plan has taken an uncertain tax position that more likely than not would not be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2022, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2019.

Although it has not expressed any intent to do so, the AstraZeneca North America HR Sub-Committee has the right under the Plan to amend or terminate the Plan at any time, subject to the provisions of ERISA and other applicable laws. In the event of Plan termination, participants would be 100 percent vested in their employer contributions.

Certain Plan investments are shares of mutual funds managed by affiliates of Fidelity Investment Management Company. Fidelity Investment Management Company is the trustee as defined in the Plan, and therefore, these transactions qualify as party-in-interest transactions.

The Plan also invests in shares of AZ Common Stock, which qualifies as a party-in-interest transaction. As of December 31, 2022 and December 31, 2021, the fair value of investments in AZ Common Stock was $167,148,357 and $151,257,134, respectively. During the year ended December 31, 2022, the Plan had no purchases and had sales of $11,917,739 of AZ Common Stock. The total dividend income received during 2022 was $3,681,473. The total realized and unrealized gain/(loss) during 2022 was $24,272,749.

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. 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 the amounts reported in the statement of net assets available for benefits.

Effective January 1, 2021, the Plan document was amended and restated in order to incorporate the prior plan amendments (#1-12) and supercedes the prior version of the Plan document which was the second restatement of the Plan effective January 1, 2016.

Plan Amendment No. 1 was executed on August 4, 2022 and revised the Plan compensation definition for purposes of determining participants’ AZ Retirement Company Contributions as well as allowed for post-severance loan repayments.
