EY-Parthenon Expands Services for Comprehensive Client Support
In a significant move to enhance its strategic consulting and transaction services, EY-Parthenon is set to undergo a major restructuring on July 1, 2025. EY Strategy and Consulting Co., Ltd., based in Chiyoda, Tokyo, will expand EY-Parthenon’s offerings to provide unified support spanning from strategy formulation to M&A assistance. This integration is aimed at fortifying the firm’s capabilities in delivering end-to-end services under the EY-Parthenon brand, reaching clients across the globe.
Redefining Strategy and Transactions
The restructuring will see EY-Parthenon redefined as a one-stop brand that combines strategy consulting and transaction services. With this new framework, EY-Parthenon will deliver high-quality, comprehensive services across various domains, including:
- - Strategy formulation and execution support
- - M&A transactions, divestitures, and corporate finance
- - Value creation, business revitalization, and portfolio optimization
- - Sector-specific strategic advisory and transformation support
This expansion comes on the heels of EYSC’s previous integration of the Strategy and Transactions and Consulting service lines in 2020, fostering collaboration with industry-specific teams. The goal is to provide clients and society with sustainable value through a cohesive integration of strategic planning, M&A activities, and organizational transformation.
Vision from Leadership
Hiroshi Kawaguchi, who will lead EY-Parthenon starting July 2025, emphasized the brand’s commitment to excellence in professional services. He noted that while EY-Parthenon has traditionally focused on strategy consulting, post-M&A financial advisory, value modeling, and financial due diligence will also fall under its umbrella.
Kawaguchi stated, "We aim to harness the collective intelligence of EY-Parthenon professionals to not only identify and evaluate challenges through effective due diligence but also to provide solutions that enhance the value of acquired businesses and assets post-transaction. Our enhanced service offerings will create more seamless support for our clients, ultimately striving to boost their corporate value."
