Business Acquisitions	Note 4. Business Acquisitions OpNet We historically owned 47.4% of the common shares and 50.0% of the voting rights of OpNet, a fixed wireless broadband service provider in Italy, and various classes of convertible preferred stock issued by OpNet (the “preferred shares”). On November 30, 2023, we provided notice of our intent to convert certain classes of our preferred shares into common shares and, as a result, we obtained control of OpNet. Upon conversion on May 7, 2024, our ownership increased to 57.5% of the common shares and our voting rights increased to 72.5% of the aggregate voting rights of OpNet. Upon obtaining control of OpNet on November 30, 2023, the assets and liabilities of OpNet have been included in our consolidated financial statements under the acquisition method of accounting. The initial consolidation of OpNet was accounted for under the acquisition method of accounting and we remeasured our previously existing interests at fair value and recognized a gain of $115.8 million, representing the excess of the fair value of our previously existing interests over the carrying value of our investment of $201.6 million. The fair value of the previously existing interests was measured based on an estimate of what could be recognized in a sale transaction for wholesale net operating assets operating assets of OpNet, which have been classified as held for sale. The remaining identifiable assets and assumed liabilities of OpNet represented the assets and liabilities of Tessellis S.p.A. (“Tessellis”), a telecommunications company publicly listed on the Italian stock exchange. An enterprise value for Tessellis was estimated based on its market capitalization at November 30, 2023, which was then allocated to the identifiable assets, including intangible assets, liabilities, and noncontrolling interests of Tessellis using an income approach, which calculates the present value of the estimated economic benefit of future cash flows, in order to determine the fair value of the identified customer relationships and Tessellis trade name. Property and equipment and developed technology assets were valued using a replacement cost methodology. Critical estimates included future expected cash flows, including forecasted revenues and expenses, and applicable discount rates. Discount rates used to compute the present value of expected net cash flows were based upon estimated weighted average cost of capital. The initial allocation of the purchase price resulted in the recognition of goodwill relating to Tessellis of $127.1 million. No consideration was transferred in connection with the consolidation. The initial estimated purchase price allocation as of November 30, 2023 for Tessellis was revised during the first quarter of 2024 as new information was received and analyzed resulting in an increase in intangible assets of $39.3 million, a decrease in property and equipment of $12.3 million, and a decrease in goodwill of $27.0 million. In February 2024, OpNet agreed to sell substantially all of its wholesale operating assets to Wind Tre S.p.A., a subsidiary of CK Hutchison Group Telecom Holdings Ltd. The sale closed in August 2024 and we received net cash proceeds of $322.8 million and recognized a pre-tax gain on sale of $3.5 million. The sale of OpNet’s operating assets did not include our interest in Tessellis. During 2024, Tessellis executed various acquisitions and, as a result, recognized assets and liabilities of $27.9 million and $20.2 million, respectively, on the acquisition dates. Total assets primarily relate to goodwill, property and equipment, intangible assets, and short-term trade receivables. Total liabilities primarily relate to financial debt assumed and trade payables. The primary acquisition executed during 2024 was the acquisition of a 97.2% ownership interest in Go Internet S.p.A. (“Go Internet”) for a total consideration of €4.2 million. During the second quarter of 2025, purchase price allocation adjustments were finalized.
