**Item 1.01 Entry into a Material Definitive Agreement.**

As a consequence of BeiGene, Ltd.'s (BeiGene) ongoing growth, effective January 30, 2023, we entered into Amendment No. 3 (Amendment No. 3) to the Share Purchase Agreement, dated October 31, 2019 (the Share Purchase Agreement), by and between Amgen Inc. (the Company) and BeiGene, to relinquish our right to appoint a director to the Board of Directors (Board) of BeiGene, and as a result, our equity investment in BeiGene will move from the equity method of accounting to the fair value method of accounting. The foregoing description of the terms of Amendment No. 3 does not purport to be complete and is qualified in its entirety by reference to the full text of the agreement, which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

**Item 2.02 Results of Operations and Financial Condition.**

<u>Fourth Quarter 2022 Earnings Press Release and Reconciliation of Non-GAAP Financial Measures</u>

On January 31, 2023, the Company issued a press release announcing its unaudited results of operations for the three months and year ended December 31, 2022, and its unaudited financial position as of December 31, 2022. The full text of the press release is furnished as Exhibit 99.1 hereto.

In its press release the Company included certain non-U.S. Generally Accepted Accounting Principles (GAAP) financial measures as defined in Regulation G promulgated by the Securities and Exchange Commission. The non-GAAP financial measures included in the press release are non-GAAP earnings per share, non-GAAP operating income, non-GAAP operating margin, non-GAAP tax rate, non-GAAP net income, non-GAAP other (expense) income, net, non-GAAP interest expense, net, non-GAAP operating expenses and sub-components of non-GAAP operating expenses such as non-GAAP cost of sales, non-GAAP research and development (R&D) expenses and non-GAAP selling, general and administrative expenses. Reconciliations for such non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the press release. The Company included Free Cash Flow (FCF), which is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP. The Company included Total Revenues and Product Sales Adjusted for Foreign Currency Exchange Rate Impact, which is computed by converting our current period local currency product sales using the prior period foreign currency exchange rates and comparing that to our current period product sales. The Company also included Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA), calculated by adding interest expense, provision for income taxes, and depreciation and amortization expense to GAAP net income, and debt leverage ratio, calculated as the ratio of GAAP total debt to EBITDA.

The Company believes that this presentation of non-GAAP financial measures provides useful supplementary information to and facilitates additional analysis by investors. The Company uses certain non-GAAP financial measures to enhance an investor's overall understanding of the financial performance and prospects for the future of the Company's ongoing business activities by facilitating comparisons of results of ongoing business operations among current, past and future periods. The Company believes that FCF provides a further measure of the Company's liquidity. The Company believes that Total Revenues and Product Sales Adjusted for Foreign Currency Exchange Rate Impact provides supplementary information on the Company's product sales performance by excluding changes in foreign currency exchange rates between comparative periods. Further, the Company believes its debt leverage ratio provides an important ongoing operating metric as it compares the amount of cash generated by our operations during a given period relative to our debt obligations outstanding for the same period. The Company uses non-GAAP financial measures in connection with its own budgeting and financial planning internally to evaluate the performance of the business, including to allocate resources and to evaluate results relative to incentive compensation targets. The non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

The following is a summary of the costs and other items excluded from the most directly comparable GAAP financial measures to calculate non-GAAP financial measures:

&nbsp;&nbsp;&nbsp;&nbsp;• Acquisition-related expenses: Acquisition-related charges are primarily associated with intangible assets acquired in connection with business acquisitions. Such charges include amortization of developed-product-technology rights, licensing rights, R&D technology rights, and marketing-related rights, as well as impairments of in-process R&D assets. Charges for purchased intangible assets are significantly impacted by the timing and magnitude of the Company's acquisitions and potential product approvals as they relate to in-process R&D projects acquired. Accordingly, these charges may vary in amount from period to period. The Company excludes these charges for purposes of calculating the non-GAAP financial measures presented to facilitate a more meaningful evaluation of the Company's current operating performance and comparisons to past operating performance. The Company believes that excluding the noncash charges related to those intangible assets acquired in business acquisitions treats those assets as if the Company had developed them internally in the past and, thus, provides a supplemental measure of profitability in which the Company's acquired intellectual property is treated in a comparable manner to its internally-developed-intellectual property.

------

&nbsp;&nbsp;&nbsp;&nbsp;• Net charges pursuant to the Company's costs savings initiatives: Costs from cost savings initiatives are primarily related to facilities charges, including accelerated depreciation, and severance and benefits for employees terminated pursuant to our transformation and process improvement efforts. Costs from such initiatives are inconsistent in amount and are significantly impacted by the timing and nature of these events. Therefore, although the Company may incur these types of expenses in the future, it believes that eliminating these charges for purposes of calculating the non-GAAP financial measures provides a supplemental evaluation of the Company's current operating performance and facilitates comparisons to past operating performance.

&nbsp;&nbsp;&nbsp;&nbsp;• Other items: The Company adjusts GAAP financial results for certain income and expenses (or gains and losses). These adjustments include (1) certain items from investment transactions, including amortization and impairments from the basis difference that arises from certain equity method investments and certain gains and losses on our investments in equity securities that are recorded to other income and expense; (2) the impact of nonstrategic divestitures, which includes cumulative foreign currency translation adjustments; (3) certain items associated with judgments and/or settlements for legal proceedings discussed in our filings; and (4) amortization of the bridge credit facility fee associated with our proposed acquisition of Horizon Therapeutics plc (Horizon) that is recorded to interest expense. The Company excludes these items for the purpose of calculating the non-GAAP financial measures presented because the Company believes these items are outside the ordinary course of business. The Company believes eliminating these items provides a supplemental evaluation of the Company's current operating performance and facilitates comparisons to past operating performance.

&nbsp;&nbsp;&nbsp;&nbsp;• The tax effect of the adjustments between GAAP and non-GAAP results take into account the tax treatment and related tax rate(s) that apply to each adjustment in the applicable tax jurisdiction(s). Generally, this results in a tax impact at the U.S. marginal tax rate for certain adjustments, including the majority of amortization of intangible assets, whereas the tax impact of other adjustments, including expenses related to cost savings initiatives, depends on whether the amounts are deductible in the respective tax jurisdictions and the applicable tax rate(s) in those jurisdictions.

The press release also contains a discussion of the additional purposes for which the Company's management uses these non-GAAP financial measures.

<u>Presentation of Non-GAAP Financial Results to Reflect Updated Non-GAAP Policy</u>

Beginning with the first quarter of 2022, the Company has modified its presentation of non-GAAP results and no longer excludes any upfront or milestone payments for licensing or collaboration agreements (regardless of the dollar amount), asset acquisitions of pre-approval, in-process R&D assets, or premiums paid on equity investments to the extent that such premiums are expensed as part of an upfront payment, from its non-GAAP measures. This change in our non-GAAP policy does not affect the Company's non-GAAP results for the three months and year ended December 31, 2022, however it does affect previously presented three months and year ended December 31, 2021, non-GAAP results, as the Company had charges related to those items during those periods. Prior period results have been recast to conform to this new non-GAAP policy. Furnished pursuant to this Item 2.02 as Exhibit 99.2 hereto is the recast presentation of the Company's 2021 non-GAAP results to reflect our updated non-GAAP policy.

This information and the information contained in the press release and recast presentation of the Company's 2021 non-GAAP financial results shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section. The information in Item 2.02 of this Current Report is not incorporated by reference into any filings of the Company made under the Securities Act of 1933, as amended, whether made before or after the date of this Current Report, regardless of any general incorporation language in the filing unless specifically stated so therein.

**Item 8.01 Other Events.**

On January 30, 2023, the Company and Horizon each received a request for additional information and documentary materials (the Second Request) from the Federal Trade Commission (the FTC) in connection with the FTC's review of the Company's proposed acquisition of Horizon (the Transaction). The effect of the Second Request is to extend the waiting period imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the HSR Act), until 30 days after the Company and Horizon have substantially complied with the Second Request, unless that period is extended voluntarily by the Company and Horizon or terminated sooner by the FTC. Both the Company and Horizon expect to promptly respond to the Second Request and to continue to work cooperatively with the FTC in its review of the Transaction. Completion of the Transaction remains subject to the expiration or termination of the waiting period under the HSR Act and the satisfaction or waiver of the other closing conditions specified in the Transaction Agreement, dated December 11, 2022, by and among the Company, Pillartree Limited and Horizon.

**AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2022 FINANCIAL RESULTS**

 **AMGEN ALSO PROVIDES 2023 GUIDANCE EXCLUDING ANY CONTRIBUTION FROM THE ANNOUNCED ACQUISITION OF HORIZON THERAPEUTICS**

THOUSAND OAKS, Calif. (January 31, 2023) - Amgen (NASDAQ:AMGN) today announced financial results for the fourth quarter and full year 2022 versus comparable periods in 2021.

***"We executed effectively in 2022, delivering strong volume growth, advancing numerous first-in-class medicines in our pipeline, and staying on track to achieve our long-term growth objectives," said Robert A. Bradway, chairman and chief executive officer. "The announced acquisition of Horizon Therapeutics, which we expect to complete in the first half of this year, represents a compelling opportunity to serve more patients and strengthen our growth profile."***

Key results include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For the fourth quarter, total revenues were $6.8 billion, largely unchanged from Q4 2021. Q4 revenues benefited from a 4% increase in product sales, offset by lower Other Revenue from our COVID-19 manufacturing collaboration. Product sales growth was driven by 10% volume growth, partially offset by 3% lower net selling price and 2% negative impact from foreign exchange. Excluding the 2% negative impact of foreign exchange on product sales, total revenues increased 2%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Volume growth of 10% included double-digit volume growth for a number of products including LUMAKRAS<sup>®</sup>/LUMYKRAS™ (sotorasib), Nplate<sup>®</sup> (romiplostim), EVENITY<sup>®</sup> (romosozumab-aqqg), Repatha<sup>®</sup> (evolocumab), Parsabiv<sup>®</sup> (etelcalcetide), AMGEVITA™ (adalimumab), KYPROLIS<sup>®</sup> (carfilzomib), and Prolia<sup>®</sup> (denosumab).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** For the full year, total revenues increased 1% to $26.3 billion, resulting from a 2% increase in product sales driven by a 9% increase in volume, partially offset by 5% lower net selling price and 2% negative impact from foreign exchange. Excluding the 2% negative impact of foreign exchange on product sales, total revenues increased 3% for the full year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GAAP earnings per share (EPS) decreased 11% from $3.36 to $3.00 in the fourth quarter driven by increased other expense, partially offset by lower weighted-average shares outstanding in Q4 2022. For the full year, GAAP EPS increased 18% from $10.28 to $12.11, primarily driven by the write-off of $1.5 billion in Acquired In-Process Research & Development (Acquired IPR&D) associated with our acquisition of Five Prime Therapeutics in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ For the fourth quarter, GAAP operating income decreased from $2.3 billion to $2.2 billion, and GAAP operating margin decreased 2.7 percentage points to 34.0%. For the full year, GAAP

operating income increased from $7.6 billion to $9.6 billion, and GAAP operating margin increased 7.2 percentage points to 38.6%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Non-GAAP EPS decreased 7% from $4.40 to $4.09 in the fourth quarter, driven by increased other expense, partially offset by lower weighted-average shares outstanding in Q4 2022. For the full year, non-GAAP EPS increased 27% from $13.92 to $17.69 driven by the write-off of $1.5 billion in Acquired IPR&D associated with our acquisition of Five Prime Therapeutics in 2021 and lower weighted-average shares outstanding in 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ For the fourth quarter, non-GAAP operating income remained unchanged at $3.0 billion, and non-GAAP operating margin decreased 1.9 percentage points to 45.9%. For the full year, non-GAAP operating income increased from $10.5 billion to $12.8 billion, and non-GAAP operating margin increased 8.2 percentage points to 51.5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** The Company generated $8.8 billion of free cash flow for the full year versus $8.4 billion in 2021.

*Non-GAAP EPS has been recast due to an update to our non-GAAP policy effective January 1, 2022, resulting in a $0.04 increase for the fourth quarter of 2021 and a $3.18 decrease for the full year 2021 of previously-reported non-GAAP EPS.

***General Medicine***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Prolia**<sup>®</sup> sales increased 14% year-over-year to a record $992 million for the fourth quarter and 12% for the full year, primarily driven by volume growth. Volumes grew 11% for the quarter and 10% for the full year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **EVENITY**<sup>®</sup> sales increased 57% year-over-year to a record $225 million for the fourth quarter and 48% for the full year, driven by strong volume growth across our markets. Volumes grew 62% for the quarter and 52% for the full year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Repatha**<sup>®</sup> sales increased 22% year-over-year to a record $333 million for the fourth quarter and 16% for the full year. Volume growth of 31% for the quarter and 47% for the full year was partially offset by lower net selling price. In the U.S., sales grew 9% for the full year, driven by 36% volume growth, partially offset by lower net selling price resulting from higher rebates to support and improve access for patients. Outside the U.S., sales grew 23% for the full year, driven by 58% volume growth, partially offset by lower net selling price. This volume growth and lower net selling price were both impacted by the inclusion of Repatha on China's National Reimbursement Drug List as of January 1, 2022. Repatha remains the global proprotein convertase subtilisin/kexin type 9 (PCSK9) segment leader, with over 1.5 million patients treated since launch.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Aimovig**<sup>®</sup> **(erenumab-aooe)** sales increased 27% year-over-year to a record $114 million for the fourth quarter and 31% for the full year, driven by higher net selling price, partially offset by lower volume. Going forward, we expect net selling price to decline to maintain broad formulary access for patients due to competitive dynamics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **EPOGEN**<sup>®</sup> **(epoetin alfa)** sales decreased 11% year-over-year for the fourth quarter, primarily driven by lower net selling price. For the full year, sales decreased 3%, driven by lower net selling price and lower inventory levels, partially offset by a 4% increase in volume. Going forward, we expect further declines in net selling price and volume erosion as we transition through the expiration of our contract with DaVita.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Aranesp**<sup>®</sup> **(darbepoetin alfa)** sales decreased 4% year-over-year for the fourth quarter, driven by unfavorable foreign exchange and lower net selling price, partially offset by increased volume. Sales decreased 4% for the full year, driven by lower net selling price and unfavorable foreign exchange impact, partially offset by favorable changes to estimated sales deductions and increased volume.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Parsabiv**<sup>®</sup> sales increased 35% year-over-year for the fourth quarter and 36% for the full year, primarily driven by volume growth resulting from 2022 purchases from a large dialysis organization following decreased usage in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Sensipar**<sup>®</sup>**/Mimpara™ (cinacalcet)** sales decreased 61% year-over-year for the fourth quarter, primarily driven by unfavorable changes in estimated sales deductions and unfavorable foreign exchange impact. Full year sales decreased 24%, primarily driven by volume declines in response to generic competition.

***Inflammation***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **TEZSPIRE**<sup>®</sup> **(tezepelumab-ekko)** generated $79 million of sales in the fourth quarter and $170 million in its first year of launch, driven by strong adoption in the U.S. by both allergists and pulmonologists across patients with all types of severe asthma. Healthcare providers acknowledge TEZSPIRE's unique, differentiated profile and its broad potential to treat the 2.5 million patients worldwide with severe asthma who are uncontrolled, without any phenotypic or biomarker limitation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **TAVNEOS**<sup>®</sup> **(avacopan)** was acquired on October 20, 2022 and generated $21 million of sales in the fourth quarter. TAVNEOS is a recently launched, first-in-class treatment for severe active ANCA-associated vasculitis (AAV), an autoimmune disease that leads to inflammation and eventual destruction of small blood vessels.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Otezla**<sup>®</sup> **(apremilast)** sales decreased 2% year-over-year for the fourth quarter, driven by lower net selling price and unfavorable changes to estimated sales deductions, partially offset by 7% volume growth. Full year sales increased 2%, primarily driven by 7% volume growth, partially offset by lower net selling price largely because of enhancements to our co-pay and patient assistance programs to support new patients starting treatment as well as additional rebates to improve the quality of coverage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Enbrel**<sup>®</sup> **(etanercept)** sales decreased 1% year-over-year for the fourth quarter, driven by declines in volume and net selling price, partially offset by higher year-end inventory levels. Full year sales decreased 8%, driven by a 5% unfavorable impact of changes to estimated sales deductions related to prior periods, 3% decline in volume and lower net selling price. Going forward, we expect further declines in net selling price year-over-year, driven by increased competition.

We expect Otezla and Enbrel to follow the historical pattern of lower sales in the first quarter relative to subsequent quarters due to the impact of benefit plan changes, insurance reverification and increased co-pay expenses as U.S. patients work through deductibles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **AMGEVITA™** sales increased 3% year-over-year to a record $119 million for the fourth quarter and 5% for the full year, driven by 25% volume growth for both periods, partially offset by unfavorable foreign exchange impact and lower net selling price resulting from increased competition. AMGEVITA continued to be the most prescribed adalimumab biosimilar in Europe.

***Hematology-Oncology***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **LUMAKRAS**<sup>®</sup>**/LUMYKRAS™** generated $71 million of sales for the fourth quarter and $285 million for the full year. Quarter-over-quarter sales declined 5%, driven by lower net selling price and unfavorable changes to estimated sales deductions, partially offset by 12% volume growth. Outside the U.S., LUMYKRAS has been approved in over 45 countries around the world. We are actively launching in 30 markets and pursuing reimbursement in the remaining countries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **KYPROLIS**<sup>®</sup> sales increased 14% year-over-year to a record $325 million for the fourth quarter and 13% for the full year, driven by 13% and 14% volume growth, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **XGEVA**<sup>®</sup> **(denosumab)** sales decreased 11% year-over-year for the fourth quarter, primarily driven by 4% decline in volume and unfavorable changes to estimated sales deductions, partially offset by higher net selling price. Full year sales were relatively unchanged year-over-year as higher net selling price was offset by a 2% decline in volume and unfavorable foreign exchange impact. Going forward, we expect volume will continue to be impacted by competitive dynamics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Vectibix**<sup>®</sup> **(panitumumab)** sales decreased 2% year-over-year for the fourth quarter, driven by unfavorable foreign exchange impact, partially offset by higher net selling price. Full year sales increased 2% year-over-year, driven by higher net selling price and volume growth, partially offset by unfavorable foreign exchange impact.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Nplate**<sup>®</sup> sales increased 66% year-over-year to a record $469 million for the fourth quarter and 27% for the full year, driven by volume growth. Nplate sales in the fourth quarter included $207 million related to a one-time order from the U.S. government.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BLINCYTO**<sup>®</sup> **(blinatumomab)** sales increased 24% year-over-year to a record $164 million for the fourth quarter, primarily driven by favorable changes to estimated sales deductions and higher net selling price. Sales increased 24% for the full year, driven by volume growth and higher net selling price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **MVASI**<sup>®</sup> **(bevacizumab-awwb)** sales decreased 33% year-over-year for the fourth quarter, primarily driven by lower net selling price. Sales decreased 23% for the full year, driven by lower net selling price, partially offset by volume growth. The most recently published Average Selling Price (ASP) for MVASI in the U.S. declined 38% year-over-year and 12% quarter-over-quarter. Looking forward, we expect continued net selling price erosion and declining volume driven by increased competition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **KANJINTI**<sup>®</sup> **(trastuzumab-anns)** sales decreased 55% year-over-year for the fourth quarter, driven by lower net selling price and unfavorable changes to estimated sales deductions. Sales decreased 45% for the full year, driven by lower net selling price and decline in volume. The most recently published ASP for KANJINTI in the U.S. declined 51% year-over-year and 22% quarter-over-quarter. Going forward, we expect continued net selling price deterioration and volume declines driven by increased competition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Neulasta**<sup>®</sup> **(pegfilgrastim)** sales decreased 37% year-over-year for the fourth quarter and 35% for the full year, driven by declines in both net selling price and volume. The most recent published Average Selling Price for Neulasta in the U.S. declined 29% year-over-year and 16% quarter-over-quarter. Going forward, we expect increased competition to result in further declines in net selling price and volume.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **NEUPOGEN**<sup>®</sup> **(filgrastim)** sales increased 10% year-over-year for the fourth quarter, primarily driven by favorable changes in estimated sales deductions, partially offset by volume declines.

AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2022 FINANCIAL RESULTS

**Operating Expense, Operating Margin and Tax Rate Analysis**

On a GAAP basis:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Total Operating Expenses** increased 1% year-over-year for the fourth quarter. For the full year, Total Operating Expenses decreased 9%. **Cost of Sales** margin decreased 0.7 percentage points in the fourth quarter and decreased 0.8 percentage points for the full year, primarily driven by lower COVID-19 antibody shipments and lower manufacturing cost, partially offset by acquisition-related charges and changes in our product mix. **Research & Development (R&D)** expenses decreased 2% in the fourth quarter and decreased 8% for the full year, primarily due to higher business development activity in 2021 and lower marketed product support, partially offset by higher late stage program support and research and early pipeline spend. **Selling, General & Administrative (SG&A)** expenses increased 10% in the fourth quarter and increased 1% for the full year primarily driven by expenses related to the ChemoCentryx acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Operating Margin** as a percentage of product sales decreased 2.7 percentage points to 34.0% in the fourth quarter and increased 7.2 percentage points for the full year to 38.6%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Tax Rate** decreased 3.3 percentage points in the fourth quarter and decreased 1.3 percentage points for the full year. The fourth quarter tax rate decrease was primarily due to the Five Prime Therapeutics non-deductible Acquired IPR&D expense in the prior year and net favorable items, partially offset by a nondeductible loss from a nonstrategic divestiture. The full year tax rate decrease was primarily due to the Five Prime Therapeutics non-deductible Acquired IPR&D expense in the prior year, partially offset by a nondeductible loss from a nonstrategic divestiture and net unfavorable items.

On a non-GAAP basis:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Total Operating Expenses** were unchanged for the fourth quarter and decreased 12% for the full year. **Cost of Sales** margin decreased 1.2 percentage points in the fourth quarter and decreased 0.5 percentage points for the full year, driven by lower COVID-19 antibody shipments and lower manufacturing cost, partially offset by changes in our product mix. **R&D** expenses decreased 2% in the fourth quarter and decreased 8% for the full year, primarily due to higher business development activity in 2021 and lower marketed product support, partially offset by higher late-stage program support and research and early pipeline spend. **SG&A** expenses increased 2% in the fourth quarter driven by higher marketed product support. For the full year, SG&A expenses were unchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Operating Margin** as a percentage of product sales decreased 1.9 percentage points in the fourth quarter to 45.9%, and increased 8.2 percentage points to 51.5% for the full year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Tax Rate** increased 2.8 percentage points in the fourth quarter and decreased 0.7 percentage points for the full year. The fourth quarter tax rate increase was primarily due to earnings mix and net favorable items in the prior year as compared to the current quarter. The full year tax rate decrease is primarily due to the Five Prime Therapeutics non-deductible Acquired IPR&D expense in the prior year, partially offset by net unfavorable items in the current year as compared to the prior year.

AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2022 FINANCIAL RESULTS

**Fourth Quarter Product and Pipeline Update**

The Company provided the following updates on selected product and pipeline programs:

**General Medicine**

**Repatha**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In November, results were presented from the Repatha FOURIER and FOURIER-open label extension studies demonstrating a direct relationship between lower achieved low-density lipoprotein cholesterol (LDL-C) levels, down to very low LDL-C levels <20 mg/dL, with a lower risk of cardiovascular outcomes in the long term. There was no increase in adverse safety events during the extended follow-up period of up to 8.6 years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The 2022 American College of Cardiology Expert Consensus Decision Pathway on the Role of Non-statin Therapies for LDL-Cholesterol Lowering indicated that "there appears to be no LDL-C level below which benefit ceases" for atherosclerotic cardiovascular disease patients at very high risk. Additionally, LDL-C recommendations were updated to reflect a reduction in target LDL-C levels in highest risk patients from 70 mg/dl to 55 mg/dl; a level that is not attainable for a large number of patients without PCSK9 inhibitor therapy.

**Olpasiran (AMG 890)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In November, results were presented from a Phase 2 study of olpasiran, a small interfering RNA molecule that reduces Lipoprotein(a) (Lp(a)) synthesis in the liver, demonstrating that patients with very high Lp(a) levels who received olpasiran dosed at 75 mg or above every 12 weeks had a 95% or greater reduction in Lp(a) compared to placebo at week 36. Overall, the rates of adverse events were similar in the olpasiran and placebo arms. The most common treatment-related adverse events were injection site reactions, primarily pain. These data were presented at the American Heart Association Scientific Sessions and simultaneously published in *The New England Journal of Medicine*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company has begun enrolling the double-blind, randomized, placebo-controlled, multicenter Phase 3 cardiovascular outcomes study that assesses the impact of olpasiran treatment on major cardiovascular events in participants with atherosclerotic cardiovascular disease and elevated Lp(a).

**AMG 133**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In December, results were presented from a Phase 1 study of AMG 133 a multispecific that inhibits the gastric inhibitory polypeptide receptor (GIPR) and activates the glucagon-like peptide 1 (GLP-1) receptor, demonstrating that following three monthly doses of AMG 133, participants experienced a mean percentage reduction in body weight of 14.5% at the highest dose (420 mg Q4W) by day 85. Weight loss was durable at the higher doses tested, with reductions observed for up to 150 days after the final (third) AMG 133 administration. Most treatment-emergent adverse events were mild and transient, with the majority being GI-related and resolving within 48 hours.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company has begun enrolling patients in a randomized, placebo-controlled, double-blind, dose-ranging Phase 2 study to evaluate the efficacy, safety, and tolerability of AMG 133 in overweight or obese adult patients, with or without type 2 diabetes mellitus.

**AMG 786**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A small molecule, continues to enroll patients in a Phase 1 study. This molecule has a different target than AMG 133 and other incretin based therapies.

AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2022 FINANCIAL RESULTS

**Non-GAAP Financial Measures**

In this news release, management has presented its operating results for the fourth quarters and full years of 2022 and 2021, in accordance with U.S. Generally Accepted Accounting Principles (GAAP) and on a non-GAAP basis. In addition, management has presented its full year 2023 EPS and tax guidance in accordance with GAAP and on a non-GAAP basis. These non-GAAP financial measures are computed by excluding certain items related to acquisitions, divestitures, restructuring and certain other items from the related GAAP financial measures. Beginning January 1, 2022, following industry guidance from the U.S. Securities and Exchange Commission, the Company no longer excludes adjustments for upfront license fees, development milestones and IPR&D expenses of pre-approval programs related to licensing, collaboration and asset acquisition transactions from its non-GAAP financial measures. For purposes of comparability, the non-GAAP financial results for the fourth quarter and full year of 2021 have been updated to reflect this change. Reconciliations for these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the news release. Management has presented Free Cash Flow (FCF), which is a non-GAAP financial measure, for the fourth quarters and full years of 2022 and 2021. FCF is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP. Management has presented Total Revenues and Product Sales Adjusted for Foreign Currency Exchange Rate Impact, which is a non-GAAP financial measure, for the fourth quarter and full year of 2022. Total Revenues and Product Sales Adjusted for Foreign Currency Exchange Rate Impact is computed by converting our current period local currency product sales using the prior period foreign currency exchange rates and comparing that to our current period product sales. Management has also presented Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and debt leverage ratio for 2022, both of which are non-GAAP financial measures. EBITDA is computed by adding interest expense, provision for income taxes, and depreciation and amortization expense to GAAP net income. Debt leverage ratio is calculated as the ratio of GAAP total debt to EBITDA.

The Company believes that its presentation of non-GAAP financial measures provides useful supplementary information to and facilitates additional analysis by investors. The Company uses certain non-GAAP financial measures to enhance an investor's overall understanding of the financial performance and prospects for the future of the Company's ongoing business activities by facilitating comparisons of results of ongoing business operations among current, past and future periods. The Company believes that FCF provides a further measure of the Company's liquidity. The Company believes Total Revenues and Product Sales Adjusted for Foreign Currency Exchange Rate Impact provides supplementary information on the Company's product sales performance by excluding changes in foreign currency exchange rates between comparative periods. The Company believes its debt leverage ratio provides an important ongoing operating metric as it compares the amount of cash generated by our operations during a given period relative to our debt obligations outstanding for the same period.

The Company uses the non-GAAP financial measures set forth in the news release in connection with its own budgeting and financial planning internally to evaluate the performance of the business, including to allocate resources and to evaluate results relative to incentive compensation targets. The non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeiGene, Ltd., Kyowa-Kirin Co., Ltd., or any collaboration to manufacture therapeutic antibodies against COVID-19), the performance of Otezla<sup>®</sup> (apremilast) (including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion), the Five Prime Therapeutics, Inc. acquisition, the Teneobio, Inc. acquisition, the ChemoCentryx, Inc. acquisition, or the proposed acquisition of Horizon Therapeutics plc, as well as estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes, effects of pandemics or other widespread health problems such as the ongoing COVID-19 pandemic on our business, outcomes, progress, and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. If we fail to meet the compliance obligations in the corporate integrity agreement between us and the U.S. government, we could become subject to significant sanctions. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, such as COVID-19, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing

activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful. A breakdown, cyberattack or information security breach of our information technology systems could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events.

**(a)** The adjustments related primarily to noncash amortization of intangible assets from business acquisitions.

**(b)** For the three months ended December 31, 2022, the adjustments related primarily to the change in fair values of contingent consideration liabilities. For the twelve months ended December 31, 2022, the adjustments related primarily to cumulative foreign currency translation adjustments from a nonstrategic divestiture. For the three and twelve months ended December 31, 2021, the adjustments related primarily to the change in fair values of contingent consideration liabilities.

**(c)** The adjustments related to certain acquisition items, prior period and other items excluded from GAAP earnings.

**(d)** The tax effect of the adjustments between our GAAP and non-GAAP results takes into account the tax treatment and related tax rate(s) that apply to each adjustment in the applicable tax jurisdiction(s). Generally, this results in a tax impact at the U.S. marginal tax rate for certain adjustments, including the majority of amortization of intangible assets, whereas the tax impact of other adjustments, including restructuring initiatives, depends on whether the amounts are deductible in the respective tax jurisdictions and the applicable tax rate(s) in those jurisdictions. Due to these factors, the effective tax rate for the adjustments to our GAAP income before income taxes, for the three and twelve months ended December 31, 2022, were 20.5% and 18.4%, respectively, compared to 12.0% and 20.7% for the corresponding period of the prior year.
