(1) On March 1, 2024, we completed the acquisition of 100% of the shares Elpis2, Inc. (Elpis Squared), a privately held software and services company. The purchase resulted in the addition of intangible assets of $15.0 million including $12.5 million identified core-developed technology and $2.5 million of customer contracts and relationships. The core-developed technology and customer contract and relationships will be amortized over the weighted-average five-year and three-year useful lives, respectively, using the straight-line method. Refer to Note 5: Goodwill and Note 17: Business Combination for additional information.
