Business Acquisitions, Disclosure	3. Business Acquisitions In May 2023, we acquired 100% of the shares of Evolar AB (“Evolar”), a developer of perovskite technology, for cash payments of $35.5 million, net of cash acquired of $0.5 million, and a promise to pay additional consideration of up to $42.5 million contingent on the achievement of certain technical milestones. The fair value of such contingent consideration was determined to be $18.5 million at the acquisition date. In connection with applying the acquisition method of accounting, $47.0 million of the purchase price consideration was assigned to an IPR&D intangible asset to be amortized over its useful life upon successful completion of the underlying project, $15.0 million was assigned to goodwill, $9.2 million was assigned to a deferred tax liability, and $2.0 million was assigned to property, plant and equipment. The acquired IPR&D includes technical information, know-how, and other proprietary information associated with certain production capabilities for perovskite technology. The acquisition is expected to accelerate the development of high efficiency multi-junction devices by integrating Evolar’s know-how with our existing R&D capabilities, intellectual property portfolio, and expertise in developing and commercially scaling thin film PV products. The goodwill is attributable to the acquired technical workforce of Evolar and the synergies we expect through integrating the acquired technology to accelerate the development of next-generation PV technology. The goodwill resulting from this transaction is not deductible for income tax purposes.

The entire disclosure for business combination.
