Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]

Acquisition of Horizon Therapeutics plc

On October 6, 2023, Amgen completed its acquisition of Horizon by acquiring all of the outstanding shares of Horizon for $116.50 per share in cash, representing a total consideration of approximately $27.8 billion. Horizon is a global biotechnology company focused on the discovery, development and commercialization of medicines that address critical needs of patients impacted by rare, autoimmune and severe inflammatory diseases. The acquisition, which was accounted for as a business combination, aligns with Amgen’s core strategy of delivering innovative medicines that make a significant difference for patients suffering from serious diseases and strengthens Amgen’s leading rare disease portfolio by adding first-in-class, early-in-lifecycle medicines, including TEPEZZA for thyroid eye disease, KRYSTEXXA for chronic refractory gout and UPLIZNA for neuromyelitis optica spectrum disorder. Upon its acquisition, Horizon became a wholly owned subsidiary of Amgen, and its operations have been included in our consolidated financial statements commencing on the acquisition date.

During the nine months ended September 30, 2024, the purchase price allocation of the acquisition was completed and measurement period adjustments were finalized, which included changes to the purchase price allocation that resulted in a net increase of approximately $25 million to goodwill. The measurement period adjustments resulted primarily from adjustments to acquired assets and liabilities, including deferred tax attributes, based on facts and circumstances that existed as of the acquisition date and did not result from events subsequent to the acquisition date. The adjustments did not have a significant impact on Amgen’s results of operations during the nine months ended September 30, 2024, and would not have had a significant impact on prior period results if the adjustments had been made as of the acquisition date.

The following table summarizes the final total consideration and allocated acquisition date fair values of assets acquired and liabilities assumed, inclusive of measurement period adjustments (in millions):



Cash and cash equivalents	$	681
Inventories	5,014
Property, plant and equipment, net	318
Finite-lived intangible assets – developed-product-technology rights	19,590
IPR&D	1,060
Goodwill	3,136
Deferred tax asset	795
Deferred tax liability	(2,488)
Other assets and liabilities, net	(273)
Total assets acquired, net of liabilities assumed	$	27,833

The $27.8 billion total consideration for this transaction consisted of (i) cash consideration transferred to common shareholders of $26.7 billion; (ii) cash consideration transferred to vested and outstanding stock options, outstanding restricted stock unit (RSU) awards and outstanding performance stock unit (PSU) awards of $523 million; (iii) the fair value of Amgen replacement awards (based on conversion of outstanding employee RSU awards) of $180 million representing noncash consideration; and (iv) a portion of Horizon’s debt, settled by Amgen on the acquisition closing date, of $382 million. Amgen issued 1.7 million replacement equity awards with the original vesting conditions, the fair value of which was determined based on the acquisition date fair value based on the conversion calculation.

The estimated fair values of $20.7 billion for the developed-product-technology rights and IPR&D intangible assets were determined using a multi-period excess earnings income approach that discounts expected future cash flows to present value by applying a discount rate that represents the estimated rate that market participants would use to value the intangible assets. The projected cash flows were based on certain assumptions attributable to the respective intangible asset, including estimates of future revenues and expenses, the time and resources needed to complete development and the probabilities of obtaining marketing approval from the FDA and other regulatory agencies. The developed-product-technology rights are being amortized on a straight-line basis over a weighted-average period of approximately 10 years from the acquisition date using the straight-line methodology.

The estimated fair value of the acquired inventory of $5.0 billion was determined using the comparative sales method, which uses actual or expected selling prices of inventory as the base amount to which adjustments for selling effort and a profit on the buyer’s effort are applied. The inventory fair value adjustment is being amortized using a weighted-average inventory turnover, which we estimate to approximate 27 months from the acquisition date.

A deferred tax liability of $2.5 billion was recognized on the temporary differences related to the book bases and tax bases of the acquired identifiable assets and assumed liabilities, primarily driven by the intangible assets acquired, as well as an associated deferred tax asset for anticipatory foreign tax credits of $795 million.

The excess of the acquisition date consideration over the fair values assigned to the assets acquired and the liabilities assumed of $3.1 billion was recorded as goodwill, which is not deductible for tax purposes. The goodwill value represents expected synergies from the marketed products acquired and other benefits.

Supplemental Pro Forma Financial Information

The following table presents the unaudited supplemental pro forma results of a hypothetical combined Amgen and Horizon entity for the three and nine months ended September 30, 2023, as if the acquisition of Horizon had occurred on January 1, 2022 (in millions):


	Three months ended September 30, 2023		Nine months ended September 30, 2023
Total revenues	$	7,854	$	22,728
Net income	$	902	$	3,518

The unaudited supplemental pro forma combined financial information was prepared using the acquisition method of accounting and was based on the historical financial information of Amgen and Horizon. In order to reflect the occurrence of the acquisition on January 1, 2022, the unaudited supplemental pro forma financial information includes adjustments to reflect the following: (i) incremental amortization expense based on the fair values of the identifiable intangible assets and inventory step-up; (ii) the additional interest expense associated with the issuance of debt to finance the acquisition; and (iii) the income tax impact using an estimated effective tax rate applied to the combined entity. The unaudited supplemental pro forma financial information is not necessarily indicative of what the condensed consolidated results of operations would have been had the acquisition been completed on January 1, 2022. In addition, the unaudited supplemental pro forma financial information is not a projection of future results of operations of the combined company, nor does it reflect the expected realization of any synergies or cost savings associated with the acquisition.
