Diversified Revenue Streams: Value‑Added Services & Solutions grew 20% in Q2 2026 (18% currency‑neutral) and 23% in 2025, outpacing Payment Network growth. This mix shift adds a faster‑growing second engine alongside the core network.

Resilient & Sustainable Growth: Users and engagement are trending up, with about 59 million monthly actives at end‑2025 and accelerating inflows per active alongside rising “primary banking” usage.
