DigitalGlobe announced that it has signed a three-year extension of its existing EnhancedView Service Level Agreement (SLA) with the U.S. National Reconnaissance Office (NRO), reinforcing the U.S. Government's continuing demand for commercial imagery and confidence in DigitalGlobe's current and future capabilities. The agreement, now known as EnhancedView Follow-On (EVFO), adds three option years to the current contract under the same terms and value of $300 million per year, providing continuity of service and revenue visibility potentially through August 2023 and adding $900 million of cumulative backlog. The extended SLA continues DigitalGlobe's long-standing commitment to enabling U.S. Government users to make confident and informed decisions using the higher resolution and most accurate and reliable commercial satellite imagery available. The terms of EVFO provide for continuity of capacity as GeoEye-1, WorldView-1 and WorldView-2 satellites reach end of life, by accessing capacity on the WorldView Legion constellation currently under construction. WorldView Legion will provide increased imaging capacity for government and commercial customers and higher re-visit collections when the constellation is launched in 2021. As previously announced, the NRO assumed responsibility for the EnhancedView SLA on September 1, 2018 when it exercised the first of two remaining contract option years. DigitalGlobe has also finalized a separate contract to further integrate its imagery production, distribution and operations with U.S. Government systems through a secure, cloud-based infrastructure. The additional government-funded integration will allow for closer interoperability and facilitates continuity between current and future ground and space architectures.
