FOR IMMEDIATE RELEASE

Cerillion recognised in two Gartner Market Guide reports

London, 22^nd May 2023Cerillion (AIM: CER), a leading provider of BSS/OSS-as-a-Service solutions to the telecoms industry, announced today that it has been named by Gartner in two recent Market Guide reports the Market Guide for CSP Customer Management and Experience Solutions¹ (CM&X) and the Market Guide for CSP Revenue Management and Monetization Solutions² (RM&M). Representative Vendors were identified for the reports based on product portfolio, geographic spread and progress in the last year.

Management believes that Cerillions inclusion in these two reports acknowledges the companys growing reputation and the breadth and completeness of the companys product portfolio. Cerillion BSS/OSS Suite covers all major modules of CM&X and RM&M solutions, supporting both modular delivery and end-to-end pre-integrated solutions, including a set of pre-packaged SaaS editions designed around the needs of specific market segments, which provide the fastest possible time-to-value.

According to Gartner, Inquiries with CSPs and our survey of RM&M vendors suggest that CSPs are increasingly asking for TM Forum Open APIs and TM Forum Open Digital Architecture (ODA) compliance.²

Already at gold-level certification for TM Forum Open APIs, Cerillion is leading this charge as one of only two BSS/OSS vendors with real-world certifications of its Open APIs in live customer deployments.

We are delighted to be recognised again in the latest Gartner Market Guide reports, commented Louis Hall, CEO, Cerillion. Gartner is a trusted resource, and we believe our inclusion confirms our burgeoning reputation in the industry backed up by our consistent track record of success and growth.
