25.0%, from $669 million for the nine months ended September 30, 2024 to $836 million for the nine months ended September 30, 2025. This increase was largely driven by the “customer appreciation” program deployed in the nine months ended September 30, 2024 at a value of $46 million, which lowered revenue due to the provision of a discount on one month of services to affected customers, enabling higher year -on-yeargrowth in the nine months ended September 30, 2025. In addition, revenue for the nine months ended September 30, 2025 was higher due to repricing of customer offers launched in December 2024 and the consolidation of revenue from Uklon in the nine months ended September 30, 2025, which accounted for approximately 6.9 percentage points of our 25.0% period -to-periodincrease in service revenues.
