Item 2.02 Results of Operations and Financial Condition.
Fourth Quarter 2023 Earnings Press Release and Reconciliation of Non-GAAP Financial Measures
On February 6, 2024, the Company issued a press release announcing its unaudited results of operations for the three months and year ended December 31, 2023, and its unaudited financial position as of December 31, 2023. 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 income (expense), 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 also included Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) for the year ended December 31, 2023, 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. Further, the Company believes its debt leverage ratio provides a supplemental operating metric for the full year period as it compares the amount of cash generated by our operations during the year ended December 31, 2023. 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:
Acquisition-related expenses: Acquisition-related charges are primarily associated with assets acquired in connection with business acquisitions, including intangible assets and acquired inventory. Such charges include amortization of developed-product-technology rights, licensing rights, R&D technology rights, marketing-related rights and step-up to fair value of acquired inventory, as well as net impairment charges of in-process R&D assets. Net 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 net charges may vary in amount from period to period. The Company excludes these net 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 noncash net charges related to those intangible assets and inventory 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 these acquired assets are treated in a comparable manner to the Company's internally developed or produced assets.
Net charges pursuant to the Company’s restructuring and cost savings initiatives: Costs from restructuring and cost savings initiatives are primarily related to facilities charges, including asset impairments and 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.



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 (i) certain gains and losses on our investments in equity securities and (ii) amortization from the basis difference that arose in prior periods from certain equity method investments, 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) (i) interest expense and income on senior notes issued in March 2023 and (ii) debt issuance costs and other fees related to our bridge credit agreement and term loan credit agreement, incurred prior to the closing of our acquisition of Horizon Therapeutics plc. 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.
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 and certain gains and losses on our investments in equity securities, whereas the tax impact of other adjustments, including expenses related to restructuring and 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.
This information and the information contained in the press release 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.

AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2023 FINANCIAL RESULTS

THOUSAND OAKS, Calif. (Feb. 6, 2024) - Amgen (NASDAQ:AMGN) today announced financial results for the fourth quarter and full year 2023 versus comparable periods in 2022.
“2023 was another year of performance and progress for our company.” said Robert A. Bradway, chairman and chief executive officer. “Our marketed products are reaching many more patients around the world, and we anticipate more than a dozen significant pipeline milestones in 2024.”

Key results include:
For the fourth quarter, total revenues increased 20% to $8.2 billion in comparison to the fourth quarter of 2022. Product sales grew 20%, driven by 23% volume growth, partially offset by 3% lower net selling price.
Nine brands(1) achieved record sales in the quarter, and Repatha® (evolocumab), EVENITY® (romosozumab-aqqg), Prolia® (denosumab) and BLINCYTO® (blinatumomab) delivered double-digit volume growth globally.
U.S. volume grew 26% and ex-U.S. volume grew 15%, including 46% volume growth in the Asia Pacific region.
Our performance included $954 million of sales for the period of Oct. 6 - Dec. 31 from our recent Horizon Therapeutics (Horizon) acquisition, driven by several first-in-class, early-in-lifecycle medicines such as TEPEZZA® (teprotumumab-trbw), KRYSTEXXA® (pegloticase) and UPLIZNA® (inebilizumab-cdon). Excluding the impact of these sales from Horizon, our product sales grew 5%, driven by volume growth of 9%.
For the full year, total revenues increased 7% to $28.2 billion, resulting from a 9% increase in product sales. Product sales growth was driven by 15% volume growth, partially offset by 3% lower net selling price, 1% unfavorable changes from estimated sales deductions and 1% negative impact from foreign exchange.
GAAP earnings per share (EPS) decreased 53% from $3.00 to $1.42 in the fourth quarter, driven by acquisition-related expenses and incremental operating expenses from Horizon, partially offset by increased revenues. For the full year, GAAP EPS increased 3% from $12.11 to $12.49 driven by net gains on our BeiGene, Ltd equity investment in 2023 and higher revenues, partially offset by higher operating expenses, including acquisition-related expenses and incremental expenses from Horizon.
For the fourth quarter, GAAP operating income decreased from $2.2 billion to $1.3 billion, and GAAP operating margin decreased 17.8 percentage points to 16.2%. For
(1) Includes product sales for the full fourth quarter of 2023 from UPLIZNA and KRYSTEXXA in connection with Horizon acquisition.

the full year, GAAP operating income decreased from $9.6 billion to $7.9 billion, and GAAP operating margin decreased 9.3 percentage points to 29.3%.
Non-GAAP EPS increased 15% from $4.09 to $4.71 in the fourth quarter and increased 5% from $17.69 to $18.65 for the full year, driven by increased revenues, partially offset by higher operating expenses, including incremental expenses from Horizon. Fourth quarter non-GAAP EPS was also unfavorably impacted by higher interest expense.
For the fourth quarter, non-GAAP operating income increased from $3.0 billion to $3.7 billion, and non-GAAP operating margin increased 0.8 percentage points to 46.7%. For the full year, non-GAAP operating income increased from $12.8 billion to $13.4 billion, and non-GAAP operating margin decreased 1.7 percentage points to 49.8%.
The Company generated $7.4 billion of free cash flow for the full year versus $8.8 billion in 2022. The decrease in 2023 was primarily driven by transaction expenses related to the Horizon acquisition and higher repatriation tax payments.
References in this release to “non-GAAP” measures, measures presented “on a non-GAAP basis,” “free cash flow” (computed by subtracting capital expenditures from operating cash flow), “EBITDA, or earnings before interest, taxes, depreciation and amortization” (computed 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) refer to non-GAAP financial measures. Adjustments to the most directly comparable GAAP financial measures and other items are presented on the attached reconciliations. Refer to Non-GAAP Financial Measures below for further discussion.

Product Sales Performance

Total product sales increased 20% for the fourth quarter of 2023 versus the fourth quarter of 2022. Volume grew 23%, partially offset by 3% lower net selling price. Full year product sales increased 9% versus 2022, driven by 15% volume growth, partially offset by 3% lower net selling price, 1% unfavorable changes from estimated sales deductions and 1% negative impact from foreign exchange.

General Medicine

Repatha® sales increased 25% year-over-year for the fourth quarter, driven by 35% volume growth, partially offset by lower net selling price. Full year sales increased 26%, driven by 37% volume growth, partially offset by lower net selling price. Repatha remains the global proprotein convertase subtilisin/kexin type 9 (PCSK9) segment leader, with over 2.5 million patients treated since launch.

Prolia® sales increased 12% year-over-year, to a record $1.1 billion for the fourth quarter, and 12% for the full year, primarily driven by volume growth and higher net selling price. Volume grew 10% for the quarter and 9% for the full year. In 2023, over 7.5 million patients were treated with Prolia.

Oncology

BLINCYTO® sales increased 47% year-over-year to a record $241 million for the fourth quarter and 48% for the full year, driven by 55% and 49% volume growth, respectively. Volume growth was supported by broad prescribing across academic and community settings for patients with B-cell precursor acute lymphoblastic leukemia.

Vectibix® (panitumumab) sales increased 5% year-over-year for the fourth quarter and 10% for the full year, driven by 5% and 10% volume growth, respectively.

KYPROLIS® (carfilzomib) sales increased 8% year-over-year for the fourth quarter and 13% for the full year, driven by 8% and 12% volume growth, respectively.

LUMAKRAS®/LUMYKRAS™ (sotorasib) sales increased 8% year-over-year for the fourth quarter, driven by 5% volume growth and higher net selling price. Full year sales decreased 2%, driven by unfavorable changes to estimated sales deductions, including changes related to ongoing reimbursement negotiations in France. Full year sales were also impacted by lower net selling price and lower inventory levels, partially offset by 16% volume growth.

XGEVA® (denosumab) sales increased 9% year-over-year for the fourth quarter and 5% for the full year, primarily driven by higher net selling price.

Nplate® (romiplostim) sales decreased 18% year-over-year for the fourth quarter, driven by volume decline related to timing of orders placed by the U.S. government, partially offset by volume growth across our U.S. and ex-U.S. regions. U.S. government orders were $207 million in Q4’22 compared to $62 million in Q4’23. Full year sales increased 13%, primarily driven by volume growth, including U.S. government orders. U.S. government orders were $207 million for FY’22 compared to $286 million for FY’23. Excluding these U.S. government orders, Nplate sales grew 23% year-over-year for the fourth quarter and 8% for the full year.

MVASI® (bevacizumab-awwb) sales decreased 8% year-over-year for the fourth quarter, primarily driven by lower net selling price, partially offset by 12% volume growth. Full year sales decreased 11%, primarily driven by lower net selling price, partially offset by 13% volume growth. Going forward, we expect continued net selling price erosion driven by increased competition.

KANJINTI® (trastuzumab-anns) sales decreased 33% year-over-year for the fourth quarter and 50% for the full year, driven by lower net selling price and volume decline.

Inflammation

TEZSPIRE® (tezepelumab-ekko) generated $177 million of sales in the fourth quarter. Quarter-over-quarter sales increased 10%, driven by 18% volume growth that benefited from the pre-filled, single-use pen, which was approved for self-administration by the U.S. Food and Drug Administration (FDA) in the first quarter. Healthcare providers recognize 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.





AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2023 FINANCIAL RESULTS
Page 4
Otezla® (apremilast) sales increased 2% year-over-year for the fourth quarter, driven by favorable changes to estimated sales deductions and 3% volume growth, partially offset by lower inventory levels and lower net selling price. Full year sales decreased 4%, driven by lower net selling price and lower inventory levels, partially offset by 2% volume growth.

We expect future growth for Otezla to be driven by its established efficacy and safety profile, strong payer coverage with limited prior authorization requirements and ease of administration. Otezla remains the only approved oral systemic therapy with a broad indication and is well-positioned to help the 1.5 million U.S. patients with mild-to-moderate psoriasis who cannot be optimally addressed by a topical and can benefit from a systemic treatment like Otezla.

Enbrel® (etanercept) sales decreased 8% year-over-year for the fourth quarter, driven by a 4% impact from unfavorable changes to estimated sales deductions and lower net selling price. Full year sales decreased 10%, driven by lower net selling price, lower inventory levels and a 3% impact from unfavorable changes to estimated sales deductions. Year-over-year volume remained flat, with U.S. volume growing 1% in the fourth quarter, supported by an increase in new patients starting treatment as a result of improved payer coverage. Going forward, we expect net selling price to continue to decline year-over-year, driven by higher rebates to maintain broad first-line payer coverage and changes in patient mix.

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.

AMJEVITA®/AMGEVITA™ (adalimumab) sales increased 34% year-over-year for the fourth quarter and 36% for the full year, primarily driven by 35% and 46% volume growth, respectively. Ex-U.S. sales increased 9% for the full year, driven by 20% volume growth, partially offset by lower net selling price. U.S. sales increased 43% quarter-over-quarter, driven by higher inventory levels and higher net selling price, partially offset by volume decline.

Rare Disease

Excluding TAVNEOS®, the products listed below were acquired from our Horizon transaction on Oct. 6, 2023. Sales figures reflect only sales in the period from Oct. 6 2023 through the end of the year, and not the full quarter.

TEPEZZA® (teprotumumab-trbw) generated $448 million of sales for the period. TEPEZZA is the first and only FDA-approved treatment for thyroid eye disease (TED).

KRYSTEXXA® (pegloticase) generated $272 million of sales for the period. KRYSTEXXA is the first and only FDA-approved treatment for chronic refractory gout.

UPLIZNA® (inebilizumab-cdon) generated $65 million of sales for the period. UPLIZNA is used to treat adults with neuromyelitis optica spectrum disorders (NMOSD).

TAVNEOS® (avacopan) generated $44 million of sales in the fourth quarter. Quarter-over-quarter sales increased 19%, primarily driven by volume growth. U.S. volume grew 23%




AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2023 FINANCIAL RESULTS

quarter-over-quarter. In the U.S., approximately 2,700 patients have now been treated with TAVNEOS.

Ultra rare products, which consist of RAVICTI® (glycerol phenylbutyrate), PROCYSBI® (cysteamine bitartrate), ACTIMMUNE® (interferon gamma-1b), BUPHENYL® (sodium phenylbutyrate) and QUINSAIR® (levofloxacin) generated $164 million of sales for the period.

Established Products

Total sales of our established products, which consist of EPOGEN® (epoetin alfa), Aranesp® (darbepoetin alfa), Parsabiv® (etelcalcetide) and Neulasta® (pegfilgrastim), decreased 10% year-over-year for the fourth quarter, primarily driven by lower net selling price and volume declines, partially offset by favorable changes to estimated sales deductions. Full year sales decreased 19%, driven by lower net selling price and volume declines. In the aggregate, we expect the year-over-year net selling price and volume declines for this portfolio of products to continue.

Operating Expense, Operating Margin and Tax Rate Analysis
On a GAAP basis:
Total Operating Expenses increased 50% year-over-year for the fourth quarter. For the full year, Total Operating Expenses increased 21%. Cost of Sales as a percentage of product sales increased 13.0 percentage points in the fourth quarter primarily driven by higher amortization expense from acquisition-related assets as well as higher profit share and royalties, partially offset by Puerto Rico excise tax, changes in product mix, and lower manufacturing cost. For the full year, cost of sales as a percentage of product sales increased 5.6 percentage points primarily driven by higher amortization expense from acquisition-related assets, higher profit share and royalties, and changes in product mix, partially offset by Puerto Rico excise tax. Research & Development (R&D) expenses increased 16% in the fourth quarter and increased 8% for the full year driven by higher spend in later-stage clinical programs and marketed products support, including spend from programs acquired from the Horizon acquisition. Selling, General & Administrative (SG&A) expenses increased 45% in the fourth quarter and increased 14% for the full year primarily driven by higher acquisition-related costs, in addition to commercial and general administrative expenses related to the Horizon acquisition. For the full year, this was partially offset by a decline in other marketed product spend. Other operating expenses for the full year consisted of net impairment charges for AMG 340 and Teneobio IPR&D assets in addition to expenses related to our restructuring plan initiated in the first quarter of 2023.
Operating Margin as a percentage of product sales decreased 17.8 percentage points to 16.2% in the fourth quarter and decreased 9.3 percentage points for the full year to 29.3%.
Tax Rate increased 2.4 percentage points in the fourth quarter and increased 3.7 percentage points for the full year, primarily driven by the 2022 Puerto Rico tax law change that replaced the excise tax with an income tax beginning in 2023. For the fourth quarter this was partially offset by the change in earnings mix.
On a non-GAAP basis:
Total Operating Expenses increased 18% for the fourth quarter and increased 9% for the full year. Cost of Sales as a percentage of product sales remained flat in the fourth quarter primarily driven by higher profit share and royalties, offset by Puerto Rico excise tax, changes in product mix, and lower manufacturing cost. For the full year, cost of sales as a percentage of product sales increased 1.1 percentage points primarily driven by higher profit share and royalties and changes in product mix, partially offset by Puerto Rico excise tax. R&D expenses increased 16% in the fourth quarter and increased 8% for the full year driven by higher spend in later-stage clinical programs and marketed products support, including spend from programs acquired from the Horizon acquisition. SG&A expenses increased 20% in the fourth quarter and increased 5% for the full year primarily driven by higher commercial and general administrative expenses related to the Horizon acquisition. For the full year, this was partially offset by a decline in other marketed product spend.
Operating Margin as a percentage of product sales increased 0.8 pts. percentage points to 46.7% in the fourth quarter and decreased 1.7 percentage points for the full year to 49.8%.

Non-GAAP Financial Measures
In this news release, management has presented its operating results for the fourth quarters and full years of 2023 and 2022, in accordance with U.S. Generally Accepted Accounting Principles (GAAP) and on a non-GAAP basis. In addition, management has presented its full year 2024 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 in-process research and development (IPR&D) expenses of pre-approval programs related to licensing, collaboration and asset acquisition transactions from its non-GAAP financial measures. Management has presented Free Cash Flow (FCF), which is a non-GAAP financial measure, for the fourth quarters and full years of 2023 and 2022. FCF is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP. Management has also presented Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and debt leverage ratio for 2023, 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 normal and recurring business activities by facilitating comparisons of results of normal and recurring 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 its debt leverage ratio provides a supplemental operating metric for the full year period as it compares the amount of cash generated by our operations for the year.
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.

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




AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2023 FINANCIAL RESULTS
Page 18
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. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such integration may take longer, be more difficult or cost more than expected. 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. Our business and operations may be negatively affected by the failure, or perceived failure, of achieving our environmental, social and governance objectives.

(a)The adjustments related primarily to noncash amortization of intangible assets from business acquisitions.
(b)For the three and twelve months ended December 31, 2023, the adjustments related primarily to acquisition-related costs related to our Horizon acquisition.
(c)For the three and twelve months ended December 31, 2023, the adjustments related primarily to separation costs associated with our restructuring plan initiated in early 2023.
(d)For the twelve months ended December 31, 2023, the adjustments related primarily to a net impairment charge for AMG 340. 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 the divestiture of Gensenta.
(e)For the three and twelve months ended December 31, 2023, the adjustments included (i) interest expense and income on senior notes issued in March 2023 and (ii) debt issuance costs and other fees related to our bridge credit and term loan credit agreements, incurred prior to the closing of our acquisition of Horizon.
(f)For the twelve months ended December 31, 2023, the adjustments related primarily to our BeiGene, Ltd. equity fair value adjustment.
(g)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 and certain gains and losses on our investments in equity securities, whereas the tax impact of other adjustments, including expenses related to restructuring and cost savings 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, 2023, were 18.6% and 20.3%, respectively, compared to 20.5% and 18.4% for the corresponding periods of the prior year.
(h)The adjustments related to certain acquisition items, prior period and other items excluded from GAAP earnings.
