32 Two Complementary Engines of Growth

Software Business Cloud Business (Dominance Engine) (Transformation Engine)

Altium’s strong software business is our dominance engine, and our new cloud platform Altium 365 is our transformation engine 33 Altium’s Move to the Cloud is Unlike Any Other

• Software Tools for • Collaboration Platform for Design of Electronics Realization of Electronics

• Traditional Software • Premium Services and Software Business Licensing Model Direct Monetization Cloud Business (Dominance Engine) (Transformation Engine)

On-premises Cloud Hybrid

Built-in Data Governance

Altium’s move to the cloud is from a position of strength and does not force its customers to change either their licensing model or the way they use Altium’s existing software

34 The Impact of the Move to Cloud on Altium’s Revenue

Indirect Monetization Direct Monetization

Indirect Monetization of Maintenance the Altium 365 Platform Subscription AD/365 “SaaS-like” 49.8% Subscription (6.5% as at end of Dec 2020) Software Business Cloud Business (Dominance Engine) Currently, there (Transformation Engine) Altium PCB is no direct Software Revenue monetization of 12.2% the Altium 365 Term-based Licenses platform

38.0%

Perpetual Software Licenses

Altium’s move to the Cloud will bring “SaaS-like” revenue Altium 365 provides future opportunities without changing its software licensing model for direct monetization 35 Financial data as at first half fiscal 2021 (NEXAR revenue is excluded) Altium 365 Direct Monetization
