Research and development expense

​

Research and development expense increased by $7.8 million, or 58.4%, for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. Research and development expense increased by $21.5 million, or 56.2%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increases were primarily due to increased personnel-related expense and increased  R&D related project costs. The increases in R&D expenses were driven by customer demand for new products as well as acceleration of previously-planned project expenditures which were necessary to accommodate accelerated demand projections for these products from certain customers.

The increases were primarily due to the increased business development effort in our CATV and data center businesses along with higher shipping costs.
