Note 4. Goodwill and Intangible Assets

On April 3, 2023, we acquired all outstanding equity of Voyantic Oy for an aggregate purchase price of $32.7 million. Our acquisition of Voyantic Oy adds label design, manufacturing and testing to our systems offerings, to advance the quality, reliability and readability of partner inlays. The consideration comprised (i) $3.6 million in shares of our common stock valued using the market price on the date of the acquisition, (ii) $4.6 million in deferred payments contingent upon revenue and gross margin performance over a one-year period from the acquisition date and (iii) the remainder in cash paid at closing.

We recorded the assets acquired and liabilities assumed at their estimated fair values as of the acquisition date. We recorded the excess of the purchase price over the assets acquired and liabilities assumed as goodwill. The fair value of net assets acquired, goodwill, intangible assets and deferred tax liability were $2.4 million, $15.6 million, $18.4 million and $3.7 million, respectively. The goodwill amount represents synergies we expect to realize from the business combination and assembled workforce. We allocated the goodwill to our one reporting unit and reportable segment. The acquired goodwill and intangible assets were not deductible for tax purposes.

The transaction-related costs for the acquisition were $0.1 million and $1.0 million for the three and six months ended June 30, 2024. These costs are related to the revaluation of the contingent consideration subsequent to the acquisition date and are included in general and administrative expenses in the condensed consolidated statements of operations. See Note 2. Fair Value Measures for additional information on the contingent consideration.

This acquisition did not have a material impact on our reported revenue or net loss amounts for any period presented; therefore, we have not presented historical and pro forma disclosures.

Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchase method of accounting. The following table presents goodwill as of June 30, 2024 (in thousands):

We amortize identifiable intangible assets with finite lives over their useful lives on a straight-line basis. The weighted average life of our intangible assets is approximately six years. Amortization of intangible assets was $0.5 million and $1.9 million for the three and six months ended June 30, 2024, respectively and $2.1 million for the three and six months ended June 30, 2023.
