## Overview

**Nexi** is **Europe's largest payment processor + consolidation giant**, formed from successive mergers (Nets + SIA) into **continental Europe's #1 paytech** <sup>[1][1], [2][2], [global-cro]</sup>. **Nexi joint group metrics** (post-SIA + Nets mergers):
- **2M+ merchants** (Europe's largest by merchant count)
- **120M+ cards** issued
- **21B+ annual acquiring transactions**
- **Continent Europe's #1** by merchants + cards + acquiring + cross-border tx

**Nexi-SIA merger (2020)**: **€15B all-share deal** — Italy's largest paytech consolidation <sup>[2][2], [3][3]</sup>. **SIA focuses on services to financial intermediaries** while **Nexi deals directly with merchants** — combined coverage from issuer-rails to merchant-acquiring.

**May 2026 — Italian government CDP-protective stake increase** <sup>[4][4]</sup>: Italy moves to protect Nexi from private equity; "no formal takeover proposal but timing makes future PE acquisition more difficult." Italian government treats Nexi as **strategic payment infrastructure**.

**EPI shareholder**: Nexi is a member of EPI (European Payments Initiative) — backing [Wero](https://docs.barcoder.ai/docs/standards/wero).
