 Driver  Key Elements  Comments  5G  Converged coreCloud RANInfrastructure investmentsNetwork slicingOptimizing capex/opex  Investment in 5G is a big factor driving the telecoms software and services industry. Such investments drive software spending for the network itself, for network orchestration and automation and for improvements to OSS and BSS.   Cloud  Moving current payloads to public cloudCloud native developmentCloud technology for telecoms networksPlatform data services/AIEdge computing  Cloud is disrupting the way in which all industries work, including telecoms. The biggest near-term issue is moving existing payloads to the cloud. However, there is a greater emphasis on using software offered as a service, generally in the public cloud and for new cloud-native development, including of the network itself.   Enterprise Services  SD WANIoT ecosystemsCloud IT servicesEnterprise digital experience/self servicePrivate 5G  Communications service providers ("CSPs") are placing a greater emphasis on enterprise services. There are a range of drivers including cloud IT services and IoT. SD-WAN provides lower costs and faster deployments, thereby enabling new use cases. Enterprises now expect self-service through a digital experience.   Digital Transformation  Digital experienceAutomated customer journeysCloud loop automation/lower TCOUse of cloud services/SaaSCulture change (to be like cloud providers)  The telecoms industry has been pushing digital transformation for some time and is now getting significant pay-off. Nearly all CSPs have deployed and are improving digital customer channels. Increased levels of automation lower network operational costs. All this has been made possible by underlying changes to enable the use of cloud methods and more cloud services.   Network Disaggregation  Impact of virtual networksInfrastructure capex changesInfrastructure as real estateCell densificationPrivate 5G  Digital transformation has led to network disaggregation. The full vertical integration of networks and services is no longer necessary nor always efficient. Investors such as towercos, fibrecos and hosting centres provide wholesale access to fundamental infrastructure used by many retail service providers.   Telecoms Services Industry Drivers  10  Source: Analysys Mason

 Research Analyst ViewsSelected Analyst Comments  19      Analyst  Selected Comments  Underlying ThemesInvestors are focused on 5G rollouts and SASS as a beacon for future growthLab testing for a Tier-1 U.S. service provider is seen positivelyBookings appear to show a recovery from COVID headwinds, pandemic continues to impact near-term visibility    "T&M benefited from continued fiber deployments from communication service providers. The Company also saw some catch-up spending as delayed projects from 2020 resumed. T&M bookings are returning to pre-pandemic levels and management continues to believe that there will be growth opportunities in H2/F21 from fiber network deployments, 5G infrastructure, and data center growth."  Daniel ChanApril 8, 2021"Hold"    Source: Research Reports  Robert YoungApril 8, 2021"Hold"  "…we believe [the recent run-up in EXFO shares] is driven by expectations of post-COVID recovery and 5G investment. EXFO continues to target EBITDA margins of 15% despite steady gross margin erosion. Pressure on R&D to maintain position at the front end of new technology and potential for SG&A to return to higher pre-pandemic levels exiting 2021 may pressure margins further. We believe a catalyst for valuation re-rating would be a return to margins recovery on the back of higher margin SASS sales."    "While results were a touch light, we think this is overshadowed by an acceleration in SASS bookings, and the fact that a U.S. Tier 1 operator has shortlisted EXFO's monitoring solution for its 5G network. We remain on the sidelines but view the stock's valuation as undemanding, particularly if EXFO can demonstrate a sustained acceleration in its SASS business."  Thanos MoschopoulosApril 7, 2021"Market Perform"  "In our opinion, EXFO has the potential to benefit from a valuation re-rating by harvesting incremental opportunities with the pending scale up in global 5G deployments. That said, there’s uncertainty around the timing of those deployments given COVID-19. In addition, even prior to this pandemic, this was a highly competitive market that’s historically seen constrained on operating leverage."  Richard TseApril 7, 2021"Sector Perform"
