Service Stream secures multi-year (3+1+1) Field Optimisation Agreement with Telstra

Leading essential network services company Service Stream Limited ( ASX: SSM ) is pleased to announce that it has secured a multi-year agreement with Telstra for the provision of design and construction services.

Under Telstra’s new commercial framework, Service Stream will be a key delivery partner responsible for performing design, construction and maintenance activities associated with its wireless and fixed-line infrastructure networks.

Under Telstra’s new Field Optimisation Program, Service Stream will be responsible for the provision of the following services:

• Site acquisition, design, construction and upgrade services of wireless infrastructure

The five-year agreement is for an initial period of three years, with two x one-year extension options, at Telstra’s election. The agreement is expected to transition on or around April 2021.
