UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introductory Note

Description of the Transaction

On August 21, 2015, Medivation, Inc. (the “Company”) entered into an Asset Purchase Agreement (the “Agreement”) with BioMarin Pharmaceutical Inc. (“BioMarin”) pursuant to which the Company acquired all rights to talazoparib (“talazoparib research program”), an orally available poly-ADP ribose polymerase (“PARP”) inhibitor from BioMarin. The acquired talazoparib assets include all patents, data, know-how, third party agreements, regulatory materials, and pre-commercial inventories. The Company also assumed certain costs related to talazoparib to the extent they arise after the closing of the transaction, including costs for the ongoing clinical trials of talazoparib, and commitments under certain agreements previously entered into by BioMarin and assigned to the Company.

On October 6, 2015, the Company completed the acquisition of the talazoparib research program from BioMarin. In connection with the closing of the transaction, the Company paid BioMarin an upfront cash payment of $410.0 million, and will pay BioMarin up to an additional $160.0 million upon the achievement of defined regulatory and sales-based milestones, and mid-single digit royalties on net sales of products that contain talazoparib during the royalty term specified in the Agreement.

Basis of Presentation

The determination of the accounting for the talazoparib research program acquisition as a business acquisition was based on a review of all of the pertinent facts and circumstances and was based on a number of factors outlined in Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 805, “Business Combinations,” which provides guidance in identifying a transaction as an asset acquisition or a business acquisition. After consideration of the factors outlined in the prescribed ASC guidance as well as the state of the development of the late-stage molecule acquired from BioMarin pursuant to the Agreement, it was determined that the talazoparib research program acquisition should be accounted for as a business acquisition and accounted for using the “acquisition method” of accounting.

The following unaudited pro forma condensed combined financial statements combine the historical financial information of the Company and the talazoparib research program. The unaudited pro forma condensed combined balance sheet at September 30, 2015 gives effect to the acquisition as if the acquisition had been consummated on that date. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2014 and the nine months ended September 30, 2015 are presented as if the acquisition had been completed on January 1, 2014. The unaudited pro forma condensed combined financial statements were prepared using the acquisition method of accounting are also in accordance with Article 11 of Regulation S-X.

The unaudited pro forma condensed combined financial information presented below is based on, and should be used in conjunction with (i) the Company’s historical audited consolidated financial statements, and related notes thereto, for the year ended December 31, 2014, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, (ii) the Company’s historical unaudited condensed consolidated financial statements, and related notes thereto, for the nine months ended September 30, 2015, included in the Company’s Quarterly Report for the nine months ended September 30, 2015, (iii) the historical audited financial statements, and related notes thereto, of the talazoparib research program for the year ended December 31, 2014 included as Exhibit 99.1 to this Form 8-K/A, and (iv) the historical unaudited financial statements, and related notes thereto, of the talazoparib research program for the nine months ended September 30, 2015 included as Exhibit 99.2 to this Form 8-K/A.

The Company is not aware of any material differences between the accounting policies of the Company and the talazoparib research program. Accordingly, the accompanying unaudited pro forma condensed combined financial statements do not assume any material differences in accounting policies between the Company and the talazoparib research program.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

(UNAUDITED)

(in thousands)

1. Basis of Presentation

On September 15, 2015, Medivation, Inc. (the “Company”) effected a two-for-one stock split of its common stock in the form of a stock dividend. The information of the Company’s common stock (except par value per share), par, and additional paid-in capital as of September 30, 2015 and the information of the net income per common share for the periods presented include the effect of the stock split.

2. Accounting Policies

During the preparation of the accompanying unaudited pro forma condensed combined financial statements, the Company was not aware of any material differences between the accounting policies of the Company and the talazoparib research program. Accordingly, the accompanying unaudited pro forma condensed combined financial statements do not assume any material differences in accounting policies between the Company and the talazoparib research program. The Company has not finalized its review of the historical accounting policies of the talazoparib research program. Any differences between the Company’s accounting policies and the talazoparib research program’s historical accounting policies could be significant.

3. Purchase Price Allocation

The acquisition of the talazoparib research program is accounted for as a business acquisition using the acquisition method of accounting in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic No. 805, “Business Combinations,” whereby the net assets acquired were recognized based their estimated fair values on the acquisition date. Transaction costs associated with the acquisition of the talazoparib asset were not significant.

In connection with the closing of the transaction, the Company made an upfront cash payment of $410.0 million to BioMarin Pharmaceutical Inc. (“BioMarin”). In addition, BioMarin is entitled to contingent payments totaling up to $160.0 million upon the achievement of defined regulatory and sales-based milestones, and mid-single digit royalties on net sales of products that contain talazoparib during the royalty term specified in the Agreement.

The following table presents the preliminary allocation of the purchase consideration, including the contingent consideration payable, based on fair value:

Purchase consideration:
Upfront cash payment	$	410,000
Acquisition-date fair value of contingent consideration		171,942
Total purchase consideration	$	581,942
Allocation of the purchase consideration:
Assets:
Identifiable intangible assets- IPR&D	$	573,299
Net identifiable assets acquired		573,299
Goodwill		8,643
Net assets acquired	$	581,942

The acquisition-date fair value of the contingent consideration payments totaled $171.9 million and was estimated by applying a probability-based income model using a discounted cash flow analysis for contingent regulatory and royalty payments and a Monte Carlo simulation model for the contingent sales milestone payments. Both models utilize key assumptions that included estimated revenues or completion of certain regulatory and sales milestone targets during the earn-out period, volatility, and estimated discount rates corresponding to the periods of expected payments.

Identifiable intangible assets totaled $573.3 million and consist entirely of in-process research and development (“IPR&D”) for talazoparib. As of the valuation date, the Company determined that talazoparib was the only research and development (“R&D”) project with substance, such that the project had undergone conceptual stages, and research, development, and preproduction had been started for the project. As such, no other intangible assets were identified in the transaction other than talazoparib separate from goodwill. The excess of the preliminary purchase consideration over the fair values assigned to the net assets acquired was $8.6 million, which represents the amount of goodwill resulting from the acquisition.

4. Pro Forma Adjustments

The following is a summary of the adjustments included under the heading “Pro Forma Adjustments” in the unaudited pro forma condensed combined financial statements. The fair values of the net assets acquired are based on a preliminary valuation of their fair value and may change when the final valuation is determined. Any such adjustments to the preliminary valuation could be significant.

a. Represents a $410.0 million reduction to the Company’s cash and cash equivalents for the upfront cash payment to BioMarin upon closing of the transaction.

b. Reflects the elimination of the talazoparib research program’s historical assets, liabilities, and equity, which were not acquired or assumed by the Company in connection with the Agreement and as a result are not directly attributable to the transaction.

c. Represents the preliminary estimate of the purchase price allocated to IPR&D for the talazoparib research program totaling $573.3 million and the elimination of the historical intangible assets of the talazoparib research program totaling $35.2 million. The historical talazoparib research program’s statements of operations do not include amortization of the IPR&D related to talazoparib. As of the valuation date, the Company determined that talazoparib was the only R&D project with substance, such that the project had undergone conceptual stages, and research, development, and preproduction had been started for the project. As such, no other intangible assets were identified in the transaction other than talazoparib separate from goodwill. The amount represents the preliminary estimate of the fair value assigned to the incomplete project acquired from BioMarin, which at the time of acquisition, had not yet reached technological feasibility. The fair value assigned to the IPR&D was determined using the “income approach,” which is a valuation technique that provides an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Some of the more significant assumptions used in the income approach from the perspective of a market participant include the estimated net cash flows for each year (including revenues, costs of sales, research and development costs, selling, general, and administrative costs, and working capital/contributory asset charges), the discount rate that measures the risk inherent in each future cash flow stream, the assessment of the asset’s life cycle, and competitive trends impacting the asset and each cash flow stream, as well as other factors.

The amounts are capitalized and accounted for as indefinite-lived long-term assets subject to impairment testing until completion or abandonment of the project. Upon successful completion of the project, the Company will make a determination as to the then useful life of the intangible asset and begin amortization over that period. No amortization of IPR&D is included in the pro forma financial statements.

d. Reflects the preliminary estimate of the goodwill totaling $8.6 million resulting from the difference between the purchase price and the fair value of the net assets acquired as a result of the Agreement and the elimination of historical goodwill of the talazoparib research program totaling $16.3 million.

e. Represents the preliminary fair value estimate of contingent consideration associated with the Agreement totaling $171.9 million and the elimination of historical contingent consideration of the talazoparib research program totaling $11.5 million. A portion of the contingent consideration included on the historical talazoparib balance sheet is associated with potential future financial obligations that have been assumed by the Company. These potential future obligations are included in the estimated fair value of the IPR&D described above. The preliminary fair value of the contingent consideration was estimated utilizing a model with key assumptions that included estimated revenues or completion of certain regulatory and sales-based milestones during the earn-out period,

volatility, and estimated discount rates corresponding to the periods of expected payments. The contingent consideration has been classified as long-term based upon the Company’s estimate of the timing of the potential contingent payments.

f. Reflects the elimination of changes in the fair value of contingent consideration reflected in the historical statement of operations of the talazoparib research program.

g. Reflects the estimated income tax impact of the talazoparib research program’s research and development expense and general and administrative expense, computed at the Federal statutory tax rate of approximately 35%.

h. For the year ended December 31, 2014, the computation of diluted net income per share includes the impact of the Company’s convertible notes. Additional information regarding the computation of diluted net income per common share is included in the Company’s Annual Report on Form 10-K
