related disorders (Poster View), Wednesday, June 12 at 3:30 p.m. CDT About KRYSTEXXA® (pegloticase) KRYSTEXXA ® (pegloticase) is the first and only biologic approved by the FDA to treat adults living with uncontrolled gout, a painful and debilitating inflammatory condition with which people continue to have abnormally high levels of uric acid and symptoms despite the use of conventional therapies. In 2022, the FDA approved expanding labeling to include co-administration with the immunomodulator methotrexate, based on results from the MIRROR randomized controlled trial, which showed significant improvements in efficacy and safety, including a reduction in infusion reactions. About Uncontrolled Gout Gout is a chronic, progressive inflammatory form of arthritis that is caused by high urate levels in the body. Tiny needle-like crystals can form and build up almost anywhere in the body. Patients with uncontrolled gout continue to have high levels of uric acid and ongoing symptoms of gout despite the use of oral urate-lowering therapies. Uncontrolled gout is a chronic, systemic disease, and if not addressed can have significant clinical consequences. KRYSTEXXA U.S. Indication KRYSTEXXA (pegloticase) is indicated for the treatment of chronic gout in adult patients who have failed to normalize serum uric acid and whose signs and symptoms are inadequately controlled with xanthine oxidase inhibitors at the maximum medically appropriate dose or for whom these drugs are contraindicated. Limitations of Use: KRYSTEXXA is not recommended for the treatment of asymptomatic hyperuricemia. KRYSTEXXA U.S. Important Safety Information WARNING: ANAPHYLAXIS AND INFUSION REACTIONS, G6PD DEFICIENCY ASSOCIATED HEMOLYSIS AND METHEMOGLOBINEMIA Anaphylaxis and infusion reactions have been reported to occur during and after administration of KRYSTEXXA. Anaphylaxis may occur with any infusion, including a first infusion and generally manifests within 2 hours of the infusion. Delayed hypersensitivity reactions have also been reported. KRYSTEXXA should be administered in healthcare settings and by healthcare providers prepared to manage anaphylaxis and infusion reactions. Patients should be premedicated with antihistamines and corticosteroids and closely monitored for anaphylaxis for an appropriate period after administration of KRYSTEXXA. Serum uric acid levels should be monitored prior to each infusion and treatment discontinued if levels increase to above 6 mg/dL, particularly when 2 consecutive levels above 6 mg/dL are observed. Patients at risk for glucose-6-phosphate dehydrogenase (G6PD) deficiency should be screened prior to starting KRYSTEXXA. Hemolysis and methemoglobinemia have been reported with KRYSTEXXA in patients with G6PD deficiency. KRYSTEXXA is contraindicated in patients with G6PD deficiency. CONTRAINDICATIONS In patients with G6PD deficiency. In patients with history of serious hypersensitivity reactions, including anaphylaxis, to KRYSTEXXA or any of its components. WARNINGS AND PRECAUTIONS Gout Flares: An increase in gout flares is frequently observed upon initiation of anti-hyperuricemic therapy, including KRYSTEXXA. Gout flare prophylaxis with a non-steroidal anti-inflammatory drug (NSAID) or colchicine is recommended starting at least 1 week before initiation of KRYSTEXXA therapy and lasting at least 6 months, unless medically contraindicated or not tolerated. Congestive Heart Failure: KRYSTEXXA has not been formally studied in patients with congestive heart failure, but some patients in the pre-marketing placebo-controlled clinical trials experienced exacerbation. Caution should be exercised in patients who have congestive heart failure and patients should be closely monitored following infusion. ADVERSE REACTIONS The most commonly reported adverse reactions (≥5%) are: KRYSTEXXA co-administration with methotrexate trial: gout flares, arthralgia, COVID-19, nausea and fatigue; KRYSTEXXA alone: gout flares, arthralgia, COVID-19, nausea, fatigue, infusion reactions, pain in extremity, hypertension and vomiting. KRYSTEXXA pre-marketing placebo-controlled trials: gout flares, infusion reactions, nausea, contusion or ecchymosis, nasopharyngitis, constipation, chest pain, anaphylaxis and vomiting. Please see Full Prescribing Information, including Boxed Warning. About Otezla® (apremilast) Otezla® (apremilast) is an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP). PDE4 inhibition results in increased intracellular cAMP levels, which is thought to indirectly modulate the production of inflammatory mediators. The specific mechanism(s) by which Otezla exerts its therapeutic action in patients is not well defined. Since its initial FDA approval in 2014, Otezla has been prescribed to more than 840,000 patients worldwide. About Psoriatic Arthritis Psoriatic arthritis is a chronic, inflammatory form of arthritis, which can cause swelling, stiffness and pain in and around the joints that worsens over time and can decrease physical function. It is estimated that nearly 38 million people worldwide have psoriatic arthritis. Around a third of people living with psoriasis may go on to develop psoriatic arthritis. If left untreated, psoriatic arthritis can cause disability. Otezla U.S. Indications Otezla (apremilast) is indicated for the treatment of adult patients with plaque psoriasis who are candidates for phototherapy or systemic therapy. Otezla is indicated for the treatment of adult patients with active psoriatic arthritis. Otezla is indicated for the treatment of adult patients with oral ulcers associated with Behçet's Disease. Otezla U.S. Important Safety Information Contraindications Otezla is contraindicated in patients with a known hypersensitivity to apremilast or to any of the excipients in the formulation Warnings and Precautions Hypersensitivity: Hypersensitivity reactions, including angioedema and anaphylaxis, have been reported during postmarketing surveillance. If signs or symptoms of serious hypersensitivity reactions occur, discontinue Otezla and institute appropriate therapy Diarrhea, Nausea, and Vomiting: Cases of severe diarrhea, nausea, and vomiting were associated with the use of Otezla. Most events occurred within the first few weeks of treatment. In some cases, patients were hospitalized. Patients 65 years of age or older and patients taking medications that can lead to volume depletion or hypotension may be at a higher risk of complications from severe diarrhea, nausea, or vomiting. Monitor patients who are more susceptible to complications of diarrhea or vomiting; advise patients to contact their healthcare provider. Consider Otezla dose reduction or suspension if patients develop severe diarrhea, nausea, or vomiting Depression: Carefully weigh the risks and benefits of treatment with Otezla for patients with a history of depression and/or suicidal thoughts/behavior, or in patients who develop such symptoms while on Otezla. Patients, caregivers, and families should be advised of the need to be alert for the emergence or worsening of depression, suicidal thoughts or other mood changes, and they should contact their healthcare provider if such changes occur Plaque Psoriasis: Treatment with Otezla is associated with an increase in depression. During clinical trials in patients with moderate to severe plaque psoriasis, 1.3% (12/920) of patients reported depression compared to 0.4% (2/506) on placebo. Depression was reported as serious in 0.1% (1/1308) of patients exposed to Otezla, compared to none in placebo-treated patients (0/506). Suicidal behavior was observed in 0.1% (1/1308) of patients on Otezla, compared to 0.2% (1/506) on placebo. One patient treated with Otezla attempted suicide; one patient on placebo committed suicide Psoriatic Arthritis: Treatment with Otezla is associated with an increase in depression. During clinical trials, 1.0% (10/998) reported depression or depressed mood compared to 0.8% (4/495) treated with placebo. Suicidal ideation and behavior was observed in 0.2% (3/1441) of patients on Otezla, compared to none in placebo-treated patients. Depression was reported as serious in 0.2% (3/1441) of patients exposed to Otezla, compared to none in placebo-treated patients (0/495). Two patients who received placebo committed suicide compared to none on Otezla Behçet's Disease: Treatment with Otezla is associated with an increase in depression. During the clinical trial, 1% (1/104) reported depression or depressed mood compared to 1% (1/103) treated with placebo. No instances of suicidal ideation or behavior were reported in patients treated with Otezla or treated with placebo Weight Decrease: Monitor body weight regularly; evaluate unexplained or clinically significant weight loss, and consider discontinuation of Otezla Plaque Psoriasis: Body weight loss of 5-10% occurred in 12% (96/784) of patients with moderate to severe plaque psoriasis treated with Otezla and in 5% (19/382) of patients treated with placebo. Body weight loss of ≥10% occurred in 2% (16/784) of patients treated with Otezla compared to 1% (3/382) of patients treated with placebo Psoriatic Arthritis: Body weight loss of 5-10% was reported in 10% (49/497) of patients taking Otezla and in 3.3% (16/495) of patients taking placebo Behçet's Disease: Body weight loss of >5% was reported in 4.9% (5/103) of patients taking Otezla and in 3.9% (4/102) of patients taking placebo Drug Interactions: Apremilast exposure was decreased when Otezla was co-administered with rifampin, a strong CYP450 enzyme inducer; loss of Otezla efficacy may occur. Concomitant use of Otezla with CYP450 enzyme inducers (e.g., rifampin, phenobarbital, carbamazepine, phenytoin) is not recommended Adverse Reactions Plaque Psoriasis: The most common adverse reactions (≥ 5%) are diarrhea, nausea, upper respiratory tract infection, and headache, including tension headache. Overall, the safety profile of Otezla in patients with mild to moderate plaque psoriasis was consistent with the safety profile previously established in adult patients with moderate to severe plaque psoriasis Psoriatic Arthritis: The most common adverse reactions (≥ 5%) are diarrhea, nausea, and headache Behçet's Disease: The most common adverse reactions (≥ 10%) are diarrhea, nausea, headache, and upper respiratory tract infection. Use in Specific Populations Otezla has not been studied in pregnant women. Advise pregnant women of the potential risk of fetal loss. Please click here for Otezla® Full Prescribing Information. About TAVNEOS® (avacopan) TAVNEOS® (avacopan), approved by the FDA as an adjunctive treatment of severe active ANCA-associated vasculitis (GPA/MPA), is a first-in-class, orally administered small molecule that employs a novel, highly targeted mode of action. TAVNEOS blocks the complement 5a receptor (C5aR) from binding C5a, the pro-inflammatory complement system fragment. This is presumed to block C5a-mediated neutrophil activation and migration. The precise mechanism of TAVNEOS in ANCA-associated vasculitis (GPA/MPA) has not been definitively established. About ANCA-Associated Vasculitis ANCA-associated vasculitis is an umbrella term for a group of multi-system autoimmune diseases with small vessel inflammation. Inflamed vessels may rupture or become occluded giving rise to a broad array of clinical symptoms and signs related to a systemic inflammatory response which may result in profound impairment in the kidneys, lungs and other organs. Prior to the approval of TAVNEOS in severe active ANCA-associated vasculitis (GPA/MPA), the combination of immunosuppressants most often used for the treatment of ANCA-associated vasculitis (GPA/MPA) include cyclophosphamide or rituximab, combined with daily glucocorticoids (steroids) for prolonged periods, which can be associated with significant clinical consequences. TAVNEOS U.S. Indication TAVNEOS is indicated as an adjunctive treatment of adult patients with severe active anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (granulomatosis with polyangiitis [GPA] and microscopic polyangiitis [MPA]) in combination with standard therapy including glucocorticoids. TAVNEOS does not eliminate glucocorticoid use. TAVNEOS U.S. Important Safety Information Contraindications Serious hypersensitivity to avacopan or to any of the excipients. Warning and Precautions Hepatotoxicity: Serious cases of hepatic injury have been observed in patients taking TAVNEOS, including life-threatening events. Obtain liver test panel before initiating TAVNEOS, every 4 weeks after start of therapy for six months and as clinically indicated thereafter. Monitor patients closely for hepatic adverse reactions, and consider pausing or discontinuing treatment as clinically indicated (refer to section 5.1 of the Prescribing Information). TAVNEOS is not recommended for patients with active, untreated and/or uncontrolled chronic liver disease (e.g., chronic active hepatitis B, untreated hepatitis C, uncontrolled autoimmune hepatitis) and cirrhosis. Consider the risk and benefit before administering this drug to a patient with liver disease. Serious Hypersensitivity Reactions: Cases of angioedema occurred in a clinical trial, including one serious event requiring hospitalization. Discontinue immediately if angioedema occurs and manage accordingly. TAVNEOS must not be re-administered unless another cause has been established. Hepatitis B Virus (HBV) Reactivation: Hepatitis B reactivation, including life threatening hepatitis B, was observed in the clinical program. Screen patients for HBV. For patients with evidence of prior infection, consult with physicians with expertise in HBV and monitor during TAVNEOS therapy and for six months following. If patients develop HBV reactivation, immediately discontinue TAVNEOS and concomitant therapies associated with HBV reactivation, and consult with experts before resuming. Serious Infections: Serious infections, including fatal infections, have been reported in patients receiving TAVNEOS. The most common serious infections reported in TAVNEOS group were pneumonia and urinary tract infections. Avoid use of TAVNEOS in patients with active, serious infection, including localized infections. Consider the risks and benefits before initiating TAVNEOS in patients with chronic infection, at increased risk of infection or who have been to places where certain infections are common. Adverse Reactions The most common adverse reactions (≥5% of patients and higher in the TAVNEOS group vs. prednisone group) were: nausea, headache, hypertension, diarrhea, vomiting, rash, fatigue, upper abdominal pain, dizziness, blood creatinine increased, and paresthesia. Drug Interactions Avoid coadministration of TAVNEOS with strong and moderate CYP3A4 enzyme inducers. Reduce TAVNEOS dose when co-administered with strong CYP3A4 enzyme inhibitors to 30 mg once daily. Monitor for adverse reactions and consider dose reduction of certain sensitive CYP3A4 substrates. Please see Full Prescribing Information and Medication Guide.

Amgen 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® (apremilast) (including anticipated Otezla sales growth and the timing of non-GAAP EPS accretion), our acquisitions of Teneobio, Inc., ChemoCentryx, Inc., or Horizon Therapeutics plc (including the prospective performance and outlook of Horizon's business, performance and opportunities, 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. 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, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. 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. 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. 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. The scientific information discussed in this news release related to our product candidates is preliminary and investigative. Such product candidates are not approved by the U.S. Food and Drug Administration, and no conclusions can or should be drawn regarding the safety or effectiveness of the product candidates. Further, any scientific information discussed in this news release relating to new indications for our products is preliminary and investigative and is not part of the labeling approved by the U.S. Food and Drug Administration for the products. The products are not approved for the investigational use(s) discussed in this news release, and no conclusions can or should be drawn regarding the safety or effectiveness of the products for these uses.

THOUSAND OAKS, Calif., May 2, 2024 /PRNewswire/ -- 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, including Repatha® (evolocumab), TEZSPIRE® (tezepelumab-ekko), EVENITY® (romosozumab-aqqg), BLINCYTO® (blinatumomab), and TAVNEOS® (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, including TEPEZZA® (teprotumumab-trbw), KRYSTEXXA® (pegloticase) and UPLIZNA® (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. 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® 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® (denosumab) generated $999 million of sales in the first quarter. Sales increased 8% year-over-year primarily driven by volume growth. EVENITY® sales increased 35% year-over-year to $342 million for the first quarter, primarily driven by volume growth. Oncology BLINCYTO® 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® (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® (carfilzomib) sales increased 5% year-over-year to $376 million for the first quarter, primarily driven by volume growth outside the U.S. LUMAKRAS®/LUMYKRAS™ (sotorasib) sales increased 11% year-over-year to $82 million for the first quarter, driven by volume growth. XGEVA® (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® (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® (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® 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® (apremilast) generated $394 million of sales in the first quarter. Sales increased 1% year-over-year for the first quarter. Enbrel® (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®/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®, the products listed below were added through the acquisition of Horizon on Oct. 6, 2023. TEPEZZA® (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® (pegloticase) generated $235 million of sales in the first quarter. KRYSTEXXA is the first and only FDA-approved treatment for chronic refractory gout. UPLIZNA® (inebilizumab-cdon) generated $80 million of sales in the first quarter. UPLIZNA is used to treat adults with neuromyelitis optica spectrum disorders. TAVNEOS® 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® (glycerol phenylbutyrate), PROCYSBI® (cysteamine bitartrate), ACTIMMUNE® (interferon gamma-1b), BUPHENYL® (sodium phenylbutyrate) and QUINSAIR® (levofloxacin), generated $169 million of sales in the first quarter. Established Products Our established products, which consist of EPOGEN® (epoetin alfa), Aranesp® (darbepoetin alfa), Parsabiv® (etelcalcetide) and Neulasta® (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. Product Sales Detail by Product and Geographic Region 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. Cash Flow and Balance Sheet The Company generated $0.5 billion of free cash flow in 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. The Company's first quarter 2024 dividend of $2.25 per share was declared on December 12, 2023, and was paid on March 7, 2024, to all stockholders of record as of February 16, 2024, representing a 6% increase from this same period in 2023.

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.
