Acquisitions | D. ACQUISITIONS Automated Test Equipment Technology On January 31, 2025, Teradyne acquired from Infineon Technologies AG ("Infineon") its automated test equipment technology and associated development team ("AET") based in Regensburg, Germany for a total purchase price of 17.6 million Euros, equivalent to $18.3 million, subject to customary adjustments. AET adds resources and expertise to Teradyne and strengthens the relationship between Teradyne and Infineon. The AET acquisition was accounted for as a business combination and, accordingly, the results have been included in Teradyne's Semiconductor Test segment from the date of acquisition. As of the acquisition date, Teradyne's preliminary purchase price allocation was goodwill of $1.3 million for expected synergies from combining operations, acquired intangible assets of $6.4 million, consisting of developed technology and customer relationships, with a weighted average estimated useful life of 4.6 years, and $10.7 million of net tangible assets, including $11.7 million of inventory. The fair values of the tangible and identifiable intangible assets acquired and liabilities assumed are based on management's estimates and assumptions. These estimates are based on preliminary information and may be subject to further revision as additional information is obtained during the measurement period, which may last up to 12 months from the date of acquisition. The acquisition was not material to Teradyne's condensed consolidated financial statements.
