Other Investments

Veeco has an ownership interest of less than 20% in a non-marketable investment in a separate entity, with a carrying value of $2.0 million at December 31, 2023 and 2022. The Company does not exert significant influence over this entity. This equity investment does not have a readily observable market price, and therefore the Company has elected to measure this investment at cost, adjusted for changes in observable market prices minus impairment. The investment is included in “Other assets” on the Consolidated Balance Sheets. The investment is subject to periodic impairment reviews which require judgment. The analyses include assessments of the companies’ financial condition, the business outlooks for their products and technologies, their projected results and cash flows, business valuation indications from recent rounds of financing, the likelihood of obtaining subsequent rounds of financing, and the impact of equity preferences held by Veeco relative to other investors. During the year ended December 31, 2021, the Company identified impairment indicators on the Company’s investment, and recorded a non-cash impairment charge of $1.0 million. This impairment charge was included in “Other income (expense), net” in the Consolidated Statement of Operations.
