NEC Corporation has announced a definitive agreement to acquire CSG Systems International, Inc. in an all-cash transaction valued at approximately US$2.9 billion (JPY 438.5 billion), including debt. Under the terms of the deal, NEC will pay US$80.70 per share, representing a 17.4% premium to CSG’s closing price on October 28, 2025, and a 23.1% premium to its 30-day volume-weighted average price.
The acquisition will significantly strengthen NEC’s position as a global leader in digital transformation and expand its footprint in AI- and cloud-driven software and services. By combining CSG’s proven SaaS product portfolio and customer base with NEC’s digital innovation capabilities and its subsidiary Netcracker’s deep expertise in Business Support Systems (BSS) and Operational Support Systems (OSS), the companies aim to deliver a more comprehensive and competitive offering to communication service providers and enterprise clients in high-growth sectors such as media, financial services, healthcare, retail, and logistics.
Both companies’ boards of directors have unanimously approved the transaction, which is expected to close within the 2026 calendar year, pending regulatory and shareholder approvals.
The acquisition underscores NEC’s strategy to enhance its global software-as-a-service portfolio and accelerate its transformation into a next-generation digital solutions provider.
