Question · Q3 2025
Dave Kang asked for quantification of the impact of foreign exchange (FX) and tariffs on Ribbon's financials. He also sought clarification on whether the 'mid to high single digit' percentage for federal business referred to Cloud and Edge revenue or overall revenue. Additionally, he inquired about the specific components (IP or Optical) that contributed to the decline in North America IP Optical sales in Q3 and questioned the sustainability of the strong performance in India.
Answer
CEO Bruce McClelland and CFO John Townsend clarified that the FX impact on operating expenses was just under $3 million year-over-year, primarily due to the shekel. Tariffs represented a roughly $0.5 million per quarter headwind, mainly on items like cables and steel. Mr. McClelland confirmed that the 'mid to high single digit' percentage for federal business was based on Cloud and Edge revenue, specifically high single digits of Cloud and Edge revenue in 2024. For North America IP Optical, he explained that most sales are IP or IP over DWDM, and the business tends to be lumpy, with Q3 focusing on rural broadband after a Q2 critical infrastructure project. Regarding India, Mr. McClelland noted five consecutive quarters of sustained momentum, driven by customer diversification, a strong partnership with Bardi, and a more linear deployment of IP routing, suggesting sustainability.
