On March 24, 2025, Alcon closed on agreements with certain existing shareholders of Aurion Biotech, Inc. ("Aurion") to acquire approximately 58.7% of outstanding equity for approximately $486 million and outstanding convertible notes from the same shareholders for approximately $36 million, totaling $522 million cash paid at closing. When combined with Alcon's existing 40.3% investment in Aurion, the transaction resulted in 99% ownership of Aurion on an outstanding basis. Aurion's ownership on a fully diluted basis at closing was approximately 85.0% held by Alcon and 15.0% held by non-controlling interests. This transaction supports Alcon's ophthalmic pharmaceutical portfolio expansion, including biopharmaceutical applications, with the potential to advance the first-ever corneal cell therapy candidate. The acquisition of majority interest was accounted for as a business combination that resulted in goodwill of $140 million after the preliminary purchase price allocation ("PPA") of the consideration to the fair values of acquired assets and assumed liabilities. The fair values of the acquired assets and assumed liabilities are provisional primarily due to pending final measurement of the non-controlling interests and valuation of acquired tax attributes. Total cash paid at closing, net of cash acquired, was $496 million. Refer to Note 11 for additional information, including preliminary PPA and details related to the associated non-controlling interests. Surgical - Acquisition of Cylite Pty Ltd.

The acquisition of the remaining equity interest was accounted for as a business combination that resulted in goodwill of $90 million after the preliminary PPA of the consideration to the fair values of acquired assets and assumed liabilities.
