Capitol Investment Thesis

Capitol Investment Thesis ▪ Compelling Market Opportunity. The proven success and compelling ROI of earned media to build brands in recent years, combined with the declining efficacy of traditional paid media advertising, is driving CMOs to shift their focus and marketing budgets toward e arn ed media, thereby expanding Cision’s market opportunity beyond PR software and services to include the $32 billion marketing software and ultimately the $195 billion(+) digital marketing and data markets ▪ Global Cloud - Based PR Solutions Leader. Cision is a leader in the $3 billion global communications intelligence software and services market with over $600 million of annual revenue (1) generated from a complete platform of products covering each major PR category: media monitoring, analysis, database, and distribution ▪ Highly Attractive, Heavily Diversified, Recurring Revenue Model . SaaS delivery model with subscription and recurring revenue representing approximately 82% of total revenue base, renewal rates of 82% (2) , and top 25 of 75,000+ customers representing 3% of revenues ▪ Substantial Free Cash Flow Generation . Cision’s EBITDA growth and strong free cash flow conversion (87% Adjusted EBITDA to unlevered FCF (3) ) drive rapid debt paydown, which provides an attractive base equity return ▪ Industry Standard Platform Poised for Significant Growth. Cision with the Cision Communications Cloud™ (C3), is a reference platform for earned media. With an increased focus on influencer and audience data tracking, C3 plans to deliver valuable analytics on en d u ser reach and engagement, and ultimately attribute purchase data back to key sources and provide an additional potential significant layer of recurring revenue for Cision ▪ Attractive M&A Platform and Synergy Opportunity. Cision and GTCR have deep expertise in acquiring and integrating complementary businesses and management has a successful track record of technology integration. The team is currently delivering on its i nte gration plan for PR Newswire, which is expected to bring significant cost and cross - selling synergies. Cision also has a robust pipeline of accretive and strategic acquisitions that are expected to be a meaningful contributor to growth going forward ▪ Experienced Leadership Team with a Proven Track Record . Kevin Akeroyd , CEO, built the Oracle Marketing Cloud prior to joining Cision . He has 25 years of experience in reshaping modern digital, social and mobile marketing globally. Jack Pearlstein boasts a highl y s uccessful track record as CFO of four GTCR backed companies (of which three completed IPOs) ▪ Top Tier Sponsorship. Capitol has completed two prior highly successful SPAC transactions and has a long history of building and investing in growth companies. GTCR is one of the most successful private equity firms in the nation with a long track record of investin g i n, building and growing technology companies ▪ Attractive Valuation.
