Precursor B-Cell Lymphoblastic Leukemia-Lymphoma

Iomab-B significantly improved outcomes in TP53 positive patients with a median overall survival of 5.49 months versus 1.66 months in those not receiving Iomab-B (hazard ratio = 0.23, p-value=0.0002) in the Phase 3 SIERRA Trial The results demonstrate Iomab-B's ability to overcome the negative impact of a TP53 mutation in these patients who otherwise would have limited treatment options and dismal prognosis Five presentations include two upcoming oral presentations detailing improved outcomes in SIERRA trial patients ages 65+ and demonstration of robust engraftment with Iomab-B NEW YORK, Feb. 23, 2024 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a leader in the development of targeted radiotherapies, today highlighted results from three poster presentations at the 2024 Tandem Meetings | Transplantation & Cellular Therapy (TCT) Meetings of ASTCT® (American Society for Transplantation and Cellular Therapy and CIBMTR® (Center for International Blood and Marrow Transplant Research) being held in San Antonio, Texas. The posters detailed results and findings from the Phase 3 SIERRA trial of Iomab-B (131I-Apamistamab) including; improved rates of Complete Remission (CR), durable Complete Remission (dCR) and survival in patients with a TP53 mutation, key aspects of radiopharmaceutical dosimetry as related to Iomab-B, and early results from a Phase 1 study demonstrating safety and lymphodepletion from Iomab-ACT conditioning with CD19 CAR-T therapy. Dr. Avinash Desai, Actinium's Chief Medical Officer, said, "Patients with a TP53 mutation have a desperate need for viable treatment options to improve outcomes. As seen in the SIERRA trial, Iomab-B led bone marrow transplant can overcome the negative impact of a TP53 mutation, producing complete remissions in more than 50% of patients as well as significant durable complete remissions. This is in stark contrast to the 0% complete remission and durable complete remission rate seen in the TP53 positive patients on the control arm who received best available treatment based on physician's choice. We are excited to further highlight these important outcomes to the transplant community and look forward to presenting additional findings from the SIERRA trial in our upcoming oral presentations." The presented Iomab-B Phase 3 SIERRA trial results and highlights include: Response Rate by TP53 Mutational Status and Treatment CR = Complete Remission Improved Survival with Iomab-B Upcoming Iomab-B Phase 3 SIERRA Trial 2024 TCT Oral Presentations: Title: 131I-Apamistamab Improves Outcomes in Patients 65 Years and Older with Relapsed or Refractory AML Date & Time: Saturday, February 24, 2024, at 11:45 AM Title: Targeted Myeloablative Radiation Using 131I-Apamistamab Prior to Allogeneic Hematopoietic Cell Transplant for Patients with R/R AML Results in Robust Engraftment Date & Time: Saturday, February 24, 2024, at 10:30 AM In addition, Actinium presented results from its ongoing phase 1 trial using Iomab-ACT as conditioning prior to CD19 CAR-T therapy for patients with relapsed or refractory B-cell Acute Lymphoblastic Leukemia or Diffuse Large B-cell Lymphoma. Importantly, no patients (0/4) developed immune effector cell-associated neurotoxicity syndrome (ICANS) of any grade, a major safety measure of the study, as ICANS is observed in 25% or more of pts w/ R/R B-ALL and DLBCL treated with various CAR T-cell products. Iomab-ACT demonstrated transient depletion of peripheral blood lymphocytes and monocytes. Persistence of CAR T-cells up to 8 weeks and minimal non-hematologic toxicities have been observed to date.

THOUSAND OAKS, Calif., Feb. 6, 2024 /PRNewswire/ -- 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 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. (1) Includes product sales for the full fourth quarter of 2023 from UPLIZNA and KRYSTEXXA in connection with Horizon acquisition. 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. EVENITY® sales increased 41% year-over-year to a record $318 million for the fourth quarter and 47% for the full year, driven by strong volume growth. U.S. volume grew 44% year-over-year and volume outside the U.S. grew 55% for the full year. Aimovig® (erenumab-aooe) sales decreased 32% year-over-year for the fourth quarter and 22% for the full year, driven by lower net selling price. 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. 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% 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. Product Sales Detail by Product and Geographic Region 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%. Tax Rate increased 2.5 percentage points in the fourth quarter and increased 2.7 percentage points for the full year primarily due to the 2022 Puerto Rico tax law change that replaced the excise tax with an income tax beginning in 2023. Cash Flow and Balance Sheet The Company generated $0.3 billion of free cash flow in the fourth quarter of 2023 versus $2.3 billion in the fourth quarter of 2022, primarily driven by timing of federal and repatriation tax payments. The Company generated $7.4 billion of free cash flow for the full year 2023 versus $8.8 billion in 2022. The Company's fourth quarter 2023 dividend of $2.13 per share was declared on October 24, 2023, and was paid on December 8, 2023, to all stockholders of record as of November 17, 2023, representing a 10% increase from 2022. During the fourth quarter, there were no repurchases of shares of common stock. Cash and investments totaled $10.9 billion and debt outstanding totaled $64.6 billion as of December 31, 2023. Debt leverage was approximately 4.4 times EBITDA as of December 31, 2023. 2024 Guidance For the full year 2024, the Company expects: Total revenues in the range of $32.4 billion to $33.8 billion. On a GAAP basis, EPS in the range of $8.42 to $9.87, and a tax rate in the range of 11.5% to 13.0%. On a non-GAAP basis, EPS in the range of $18.90 to $20.30, and a tax rate in the range of 16.0% to 17.0%. Capital expenditures to be approximately $1.1 billion. Share repurchases not to exceed $500 million. Fourth Quarter Product and Pipeline Update The Company provided the following updates on selected product and pipeline programs: General Medicine Maridebart cafraglutide (AMG 133) A Phase 2 study of maridebart cafraglutide, a multispecific molecule that inhibits the gastric inhibitory polypeptide receptor (GIPR) and activates the glucagon like peptide 1 (GLP-1) receptor, in overweight or obese adults with or without type 2 diabetes mellitus has completed enrollment, with topline data anticipated in late 2024. The Company recently added a Part 2 to this study which explores durable weight loss beyond 52 weeks. Planning for a comprehensive Phase 3 program across multiple indications remains on track. In February 2024, results of preclinical studies and the Phase 1 study of maridebart cafraglutide were published in Nature Metabolism. AMG 786 A Phase 1 study of AMG 786, a small molecule obesity program, is ongoing with initial data readout anticipated in H1 2024. This molecule has a different target than maridebart cafraglutide and is not an incretin-based therapy. Olpasiran (AMG 890) A Phase 3 cardiovascular outcomes study of olpasiran, a potentially best-in-class small interfering ribonucleic acid (siRNA) molecule that reduces lipoprotein(a) (Lp(a)) synthesis in the liver, in patients with atherosclerotic cardiovascular disease and elevated Lp(a) continues to enroll patients. To date, over 7,000 patients have been enrolled, with enrollment completion anticipated in H1 2024. Repatha EVOLVE-MI, a Phase 4 study of Repatha administered within 10 days of an acute myocardial infarction to reduce the risk of cardiovascular events, continues to enroll patients. A Phase 3 cardiovascular outcomes study (VESALIUS-CV) in patients at high cardiovascular risk without prior myocardial infarction or stroke is ongoing. Oncology Tarlatamab (AMG 757) The U.S. Food and Drug Administration (FDA) has granted Priority Review for the Company's Biologics License Application (BLA) for tarlatamab, a first-in-class investigational delta-like ligand 3 (DLL3) targeting BiTE® (bispecific T-cell engager) molecule. The BLA is based on the results from the Phase 2 DeLLphi-301 clinical trial, which demonstrated antitumor activity with a durable response and encouraging survival outcomes in previously treated small cell lung cancer (SCLC). The safety profile was consistent with the Phase 1 trial. Based on the Priority Review designation, the Prescription Drug User Fee Act (PDUFA) date for tarlatamab is June 12, 2024.

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 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. ### CONTACT: Amgen, Thousand Oaks Jessica Akopyan, 805-440-5721 (media) Justin Claeys, 805-313-9775 (investors) * The known adjustments are presented net of their related tax impact, which amount to approximately $2.60 per share.
