On May 24, 2022, we acquired all outstanding equity interests of Antares Pharma, Inc. according to the terms and conditions of the Agreement and Plan of Merger, dated as of April 12, 2022 (the “Merger Agreement”). Antares is a specialty pharmaceutical company focused primarily on the development and commercialization of pharmaceutical products and technologies that address patient needs in targeted therapeutic areas. We acquired Antares as a part of our strategy to expand as a drug delivery company and include specialty products.

The total purchase consideration of Antares was $1,045.7 million. Each share of Antares common stock issued and outstanding was converted into the right to receive $5.60 in cash without interest, less any applicable withholding taxes (“Merger Consideration”). Additionally, in connection with the transaction, each Antares equity award granted and outstanding as of May 24, 2022 under the Antares’ equity compensation plans was converted into the right to receive Merger Consideration. Other components of purchase consideration include cash paid at closing to settle Antares existing debt of $19.7 million and seller transaction costs paid by us on behalf of Antares of $22.9 million.

The acquisition of Antares was funded by cash on hand and borrowings under the new credit agreement with Bank of America, N.A. (“BofA”) and other lenders that provides for (i) a $350 million revolving credit facility (the “Revolving Credit Facility”) and (ii) a $250 million term loan facility (the “Term Facility”, collectively with the Revolving Credit Facility, the “2022 Facility”) as described in Note 8. We recognized transaction costs of $0.4 million and $20.5 million in the three and nine months ended September 30, 2022, respectively. These costs are reported in selling, general and administrative expenses in our condensed consolidated statements of income. Transaction costs include, but are not limited to, investment banker, advisory, legal, and other professional fees.

(a) Consideration for Antares equity compensation awards consists of $32.2 million paid for vested equity awards as well as $13.6 million paid for the pre-combination portion of unvested equity awards that were accelerated as part of the Merger Agreement. The fair value of the unvested equity awards attributable to the post-combination period of $8.7 million is included in our condensed consolidated statements of income in Q2 2022 and the nine months ended September 30, 2022.

The acquisition of Antares has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, with Halozyme treated as the accounting acquirer, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their fair value on the acquisition date. Acquisition accounting is dependent upon certain valuations and other studies that have yet to commence or progress to a stage where there is sufficient information for a definitive measurement. The process for estimating the fair values of identifiable intangible assets and certain tangible assets and assumed liabilities requires the use of judgment in determining the appropriate assumptions and estimates.

The table below presents the preliminary estimated fair values of assets acquired and liabilities assumed on the acquisition date based on preliminary valuations and management estimates that are subject to change when formal valuations and other studies are finalized. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact our results of operations. These preliminary estimates may be revised during the measurement period as third-party valuations are finalized, additional information becomes available, and as additional analyses are performed. These differences could change the value of the intangible assets acquired, the contingent liability assumed, and the tax impacts related to the acquisition and could have a material impact on our results of operations and financial position.

Deferred tax liabilities, net	159,094
Other long-term liabilities	135,088
Net assets acquired, excluding goodwill	$	799,639
Goodwill	199,481

Goodwill is the excess of the consideration transferred over the net assets recognized and represents the expected revenue and cost synergies of the combined company and assembled workforce. Goodwill will be allocated entirely to the single reportable segment. Goodwill recognized as a result of the acquisition is not deductible for tax purposes.

The estimated fair values of identifiable intangible assets were prepared using the excess earnings method which calculates the present value of the incremental after-tax cash flows attributable solely to each intangible asset. The estimated useful lives are based on forecasted periods of benefit for each intangible asset which consider commercialization dates, the estimated revenue cycle based on the products’ competitiveness in the market, and the loss of exclusivity timing with subsequent trending down of revenue. For the ATRS-1902 IPR&D, the useful life is considered indefinite as the asset has not been placed into service. As such, the ATRS-1902 IPR&D will be tested annually for impairment and will not be amortized. Useful lives and preliminary values are presented in the table below.

A contingent liability with a preliminary value of $130.0 million was assumed related to TLANDO. We assumed an obligation to pay development milestone payments as well as commercial milestone payments and minimum tiered royalty payments based on TLANDO net sales which are contingent upon future events. The acquisition date fair value was measured using the income approach, specifically the probability weighted expected return method for the development milestone payments and the option pricing methodology using the Monte Carlo simulation for commercial milestone payments and royalty payments.

The unaudited pro forma financial information for all periods presented includes the business combination accounting effects resulting from this acquisition. The unaudited pro forma results include adjustments to reflect the amortization of the inventory step-up and the incremental intangible asset amortization to be incurred based on preliminary valuations of assets as well as certain material non-recurring transaction adjustments related to the acquisition. Adjustments to interest expense, financing costs and investment income were made to reflect the capital structure of the combined entity. Adjustments to income tax expense also were made to reflect the anticipated effective tax rate of the combined entity. The unaudited pro forma financial information as presented is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of fiscal year 2021, nor is it necessarily an indication of trends in future results for a number of reasons, including, but not limited to, differences between the assumptions used to prepare the pro forma information, cost savings from operating efficiencies, potential synergies, and the impact of incremental costs incurred in integrating the businesses.
