China Tower Corp. said Tuesday that its first-half net profit rose 17% from a year earlier, helped by an accelerated rollout of 5G networks in China and efficiency gains.

Net profit was 2.98 billion yuan ($428.0 million), while operating revenue rose 4.8% to CNY39.79 billion, said the company, which builds 5G base stations.

China Tower said it expects the deployment of 5G networks in the country to accelerate, which could help it achieve stable growth in its operating results.
