Amgen (NASDAQ:AMGN) today announced financial results for the first quarter 2024.

"With many of our innovative products delivering strong growth and promising new medicines advancing through our pipeline, we are excited about delivering attractive long-term growth," said Robert A.Bradway, chairman and chief executive officer.

Key results include:

-- For the first quarter, total revenues increased 22% to $7.4 billion in comparison to the first quarter of 2023. Product sales grew 22%, driven by 25% volume growth.

-- Ten products delivered at least double-digit volume growth in the first quarter, includingRepatha(R) (evolocumab), TEZSPIRE(R) (tezepelumab-ekko), EVENITY(R) (romosozumab-aqqg), BLINCYTO(R) (blinatumomab), and TAVNEOS(R) (avacopan).

-- U.S. volume grew 29% and ex-U.S. volume grew 17%.

-- Our performance included $914 million of sales from our Horizon Therapeutics (Horizon) acquisition, driven by several first-in-class, early-in-lifecycle medicines, includingTEPEZZA(R) (teprotumumab-trbw), KRYSTEXXA(R) (pegloticase) and UPLIZNA(R) (inebilizumab-cdon).

-- Excluding sales from Horizon, our product sales grew 6%, driven by volume growth of 9%.

-- GAAP loss per share was $0.21 for the first quarter of 2024 compared with GAAP earnings per share (EPS) of $5.28 for the first quarter of 2023, driven by a mark-to-market loss on our BeiGene, Ltd. equity investment and higher operating expenses, including higher amortization expense from Horizon-acquired assets and incremental expenses from Horizon, partially offset by higher revenues.

-- GAAP operating income decreased from $1.9 billion to $1.0 billion, and GAAP operating margin decreased 19.0 percentage points to 13.9%.

-- Non-GAAP EPS decreased 1% from $3.98 to $3.96, due to higher operating and interest expenses driven by the Horizon acquisition, partially offset by higher revenues.

-- Non-GAAP operating income increased from $2.8 billion to $3.1 billion, and non-GAAP operating margin decreased 5.1 percentage points to 43.2%.

-- The Company generated $0.5 billion of free cash flow for the first quarter of 2024 versus $0.7 billion in the first quarter of 2023. This decrease was driven by an $800 million tax deposit, partially offset by timing of working capital items.

References in this release to "non-GAAP" measures, measures presented "on a non-GAAP basis" and "free cash flow" (computed by subtracting capital expenditures from operating cash flow) 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 22% for the first quarter of 2024 versus the first quarter of 2023, driven by 25% volume growth.

General Medicine

-- Repatha(R) sales increased 33% year-over-year to $517 million in the first quarter, driven by 44% volume growth, partially offset by 13% lower net selling price. Repatha remains the global proprotein convertase subtilisin/kexin type 9 (PCSK9) segment leader, with over 2.9 million patients treated since launch.

-- Prolia(R) (denosumab) generated $999 million of sales in the first quarter. Sales increased 8% year-over-year primarily driven by volume growth.

-- EVENITY(R) sales increased 35% year-over-year to $342 million for the first quarter, primarily driven by volume growth.

Oncology

-- BLINCYTO(R) sales increased 26% year-over-year to $244 million for the first quarter, driven by broad prescribing across academic and community segments for patients with B-cell precursor acute lymphoblastic leukemia (B-ALL).

-- Vectibix(R) (panitumumab) generated $247 million of sales in the first quarter. Sales increased 6% year-over-year driven by higher net selling price and volume growth, partially offset by unfavorable foreign exchange impact.

-- KYPROLIS(R) (carfilzomib) sales increased 5% year-over-year to $376 million for the first quarter, primarily driven by volume growth outside the U.S.

-- LUMAKRAS(R)/LUMYKRAS™ (sotorasib) sales increased 11% year-over-year to $82 million for the first quarter, driven by volume growth.

-- XGEVA(R) (denosumab) sales increased 5% year-over-year to $561 million for the first quarter, primarily driven by volume growth outside the U.S. and higher net selling price, partially offset by lower volume in the U.S.

-- Nplate(R) (romiplostim) generated $317 million of sales in the first quarter. Sales decreased 12% year-over-year, primarily driven by volume decline in comparison to the first quarter of 2023, which included a U.S. government order of $82 million. Excluding the U.S. government order from this comparison, Nplate sales grew 13% year-over-year, primarily driven by volume growth.

-- MVASI(R) (bevacizumab-awwb) generated $202 million of sales in the first quarter. Sales were flat year-over-year for the first quarter. Volume growth was largely offset by lower net selling price and unfavorable changes to estimated sales deductions. Going forward we expect continued net selling price erosion driven by competition.

Inflammation

-- TEZSPIRE(R) generated $173 million of sales in the first quarter. Sales increased 80% year-over-year, primarily driven by volume growth. 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.

-- Otezla(R) (apremilast) generated $394 million of sales in the first quarter. Sales increased 1% year-over-year for the first quarter.

-- Enbrel(R) (etanercept) generated $567 million of sales in the first quarter. Sales decreased 2% year-over-year driven by volume decline, partially offset by higher inventory levels. Moving forward, we expect modest volume growth offset by declining net selling price.

Otezla and Enbrel typically have lower sales in the first quarter relative to subsequent quarters due to the impact of benefit plan changes, insurance reverifications and increased co-pay expenses as U.S. patients work through deductibles.

-- AMJEVITA(R)/AMGEVITA™ (adalimumab) generated $168 million of sales in the first quarter. Sales increased 2% year-over-year primarily driven by international growth, partially offset by lower inventory levels and unfavorable change to estimated sales deductions.

Rare Disease

Except for TAVNEOS(R), the products listed below were added through the acquisition of Horizon on Oct. 6, 2023.

-- TEPEZZA(R) (teprotumumab-trbw) generated $424 million of sales in the first quarter. TEPEZZA is the first and only FDA-approved treatment for thyroid eye disease (TED).

-- KRYSTEXXA(R) (pegloticase) generated $235 million of sales in the first quarter. KRYSTEXXA is the first and only FDA-approved treatment for chronic refractory gout.

-- UPLIZNA(R) (inebilizumab-cdon) generated $80 million of sales in the first quarter. UPLIZNA is used to treat adults with neuromyelitis optica spectrum disorders.

-- TAVNEOS(R) generated $51 million of sales in the first quarter. Sales increased 122% year-over-year, driven by volume growth.

-- Ultra rare products, which consist of RAVICTI(R) (glycerol phenylbutyrate), PROCYSBI(R) (cysteamine bitartrate), ACTIMMUNE(R) (interferon gamma-1b), BUPHENYL(R) (sodium phenylbutyrate) and QUINSAIR(R) (levofloxacin), generated $169 million of sales in the first quarter.

Established Products

-- Our established products, which consist of EPOGEN(R) (epoetin alfa), Aranesp(R) (darbepoetin alfa), Parsabiv(R) (etelcalcetide) and Neulasta(R) (pegfilgrastim), generated $613 million of sales. Sales decreased 19% year-over-year for the first quarter, driven by unfavorable changes to estimated sales deductions and volume declines. In the aggregate, we expect the year-over-year 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 54%. Cost of Sales as a percentage of product sales increased 15.6 percentage points driven by higher amortization expense from Horizon acquisition-related assets and, to a lesser extent, higher profit share and royalty expense, partially offset by the Puerto Rico excise tax. Research & Development (R&D) expenses increased 27% due to higher spend in later-stage clinical programs and marketed product support, including Horizon-acquired programs. Selling, General & Administrative (SG&A) expenses increased 44% primarily driven by commercial expenses related to Horizon-acquired products, general and administrative expenses, and acquisition-related costs. Other operating expenses consisted primarily of a net impairment charge for an in-process R&D asset and changes in contingent consideration liabilities, both related to our Teneobio, Inc. acquisition from 2021.

-- Operating Margin as a percentage of product sales decreased 19.0 percentage points in the first quarter to 13.9%.

-- Tax Rate decreased 83.7 percentage points primarily due to the GAAP net loss described above and the change in earnings mix as a result of the inclusion of the Horizon business.

On a non-GAAP basis:

-- Total Operating Expenses increased 33%. Cost of Sales as a percentage of product sales increased 1.4 percentage points driven by higher profit share and royalty expense, partially offset by the Puerto Rico excise tax. R&D expenses increased 26% due to higher spend in later-stage clinical programs and marketed product support, including Horizon-acquired programs. SG&A expenses increased 40%, primarily driven by commercial expenses related to Horizon-acquired products, and general and administrative expenses.

-- Operating Margin as a percentage of product sales decreased 5.1 percentage points in the first quarter to 43.2%.

-- Tax Rate decreased 2.4 percentage points primarily due to the change in earnings mix as a result of the inclusion of the Horizon business and net favorable items in the quarter.

Non-GAAP Financial Measures

In this news release, management has presented its operating results for the first quarters of 2024 and 2023, 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. Management has presented Free Cash Flow (FCF), which is a non-GAAP financial measure, for the first quarters of 2024 and 2023. FCF is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP.

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 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

This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. 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. or Kyowa Kirin Co., Ltd.), the performance of Otezla(R) (apremilast) (including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion), our acquisitions of Teneobio, Inc., ChemoCentryx, Inc., or Horizon (including the prospective performance and outlook of Horizon's business, performance and opportunities and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition, and any projected impacts from the Horizon acquisition on our acquisition-related expenses going forward), 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 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. 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. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.

AmgenInc. GAAP to Non-GAAPReconciliations (In millions, except per-share data) (Unaudited) The following table presents the computations for GAAP and non-GAAP diluted earnings per share: Three months ended Three months ended March 31, 2024 March 31, 2023 GAAP Non-GAAP GAAP Non-GAAP Net (loss) income $ (113) $ 2,140 $ 2,841 $ 2,141 Shares (Denominator): Weighted-average shares for basic (loss) earnings per share 536 536 534 534 Effect of dilutive securities (i) — 5 4 4 Weighted-average shares for diluted (loss) earnings per share (i) 536 541 538 538 Diluted (loss) earnings per share $ (0.21) $ 3.96 $ 5.28 $ 3.98

(a) The adjustments related primarily to noncash amortization of intangible assets and fair value step-up of inventory acquired from business acquisitions. (b) For the three months ended March 31, 2024, the adjustments related primarily to acquisition-related costs related to our Horizon acquisition. For the three months ended March 31, 2023, the adjustments related primarily to noncash amortization of intangible assets from business acquisitions. (c) For the three months ended March 31, 2023, the adjustments related primarily to separation costs associated with our restructuring plan initiated in early 2023. (d) For the three months ended March 31, 2024, the adjustments related primarily to a net impairment charge for an in-process R&D asset and changes in contingent consideration liabilities, both related to our Teneobio, Inc. acquisition from 2021. For the three months ended March 31, 2023, the adjustments related to changes in contingent consideration liabilities. (e) For the three months ended March 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 three months ended March 31, 2024 and 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 the amortization of acquired inventory and 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 months ended March 31, 2024, was 13.8% compared to 14.0% for the corresponding period of the prior year. (h) The adjustments related to certain acquisition items, prior period and other items excluded from GAAP earnings. (i) During periods of net loss, diluted loss per share is equal to basic loss per share as the anti-dilutive effect of potential common shares is disregarded.
