Calix Inc. has announced its financial results for the second quarter of 2025, reporting a revenue of $241.9 million, which marks a 10% increase from the previous quarter and a 22% rise compared to the same quarter last year. The company's U.S. revenue accounted for 91% of the total revenue for the quarter, showing a 4% increase in absolute dollars sequentially and a 20% increase from the year-ago quarter. Meanwhile, international revenue represented 9% of the total, experiencing a significant rise of 152% from the prior quarter and a 48% increase compared to the same period last year, primarily due to increased shipments to a European customer. Calix's GAAP gross margin reached a record 56.3%, reflecting an increase of 60 basis points sequentially and 200 basis points year-over-year. On a non-GAAP basis, which excludes stock-based compensation and intangible asset amortization, the gross margin was slightly higher at 56.8%, up 60 basis points sequentially and 170 basis points from the previous year. The company reported a net income per diluted common share of $0.332 on a non-GAAP basis, surpassing the provided guidance range of $0.18 to $0.24. The growth in subscriber revenue and healthy demand for network technology investment have been significant contributors to the financial performance. Looking ahead, Calix plans to accelerate the adoption of its platform, cloud, and managed services, aiming for expansion into new markets such as MDUs, sovereign geographies, and new customer segments, while maintaining a strong operating discipline.
