In recent months, there’s been much discussion in reputed business journals1 about potentially separating the Consulting businesses of the Big Four firms (Deloitte2, PwC, EY, and KPMG) for multiple reasons, including regulatory and financial. More recently, the Wall Street Journal’s reporting on PwC’s Global Mobility divestment and E&Y’s Project Everest3 have brought the shape of the Big Four into sharper focus. As potential acquirers of the carved-out business, Private Equities have the opportunity to acquire a select part of the Advisory arms, as well as carve-out specific service lines within Advisory to unlock their high growth potential, unburdened by Security and Exchange Commission (SEC), or Public Company Accounting Oversight Board (PCAOB), independence and compliance restrictions.
The Advisory lines of business for each of the Big Four firms are of significant size, revenue diversified, and complex (see the revenue chart below). Potential acquirers, whether individual funds or a consortium of funds, need to factor the operational complexity to determine the right valuation of these service lines and ensure that they are able to deliver investor value.
In a post-Sarbanes Oxley world, the Big Four have leveraged their Network-of-Firms model and limited liability structure to minimize risk and tax exposure across the geographies in which they operate. As a result, each country runs almost entirely independently across sales and operations, while leveraging common brand identity and marketing. This creates a network that operates with a small, central, global leadership and oversight function to provide direction. That said, its decisions are often driven by the largest territory markets (US, UK, Germany, and China), or larger revenue clusters like Western Europe. This current operating structure works well to limit liabilities and tax exposure, while avoiding major top-down decisions across the network.

Over the years, the authors have restructured and carved-out business from the Big Four firms. Here’s what they’ve learnt.
Carving-out an entity requires untangling the current legal entity and cross-holdings to determine the simplified, post-separation new legal entity structure that covers dozens of territories in more than 100 countries. This results in potentially significant tax exposure and demands multi-country tax expertise and knowledge. In select instances, closing down a legal entity might lead to a loss of tax revenue, which may attract additional scrutiny from country-specific regulators.
In each country or territory, the vendor footprint, application landscape, and tools, which are shaped by country preferences, and often, client relationships, also vary. Driving an integrated, standardized, flexible, scalable model takes time, and requires convergence with several internal and external stakeholders. The firms have integrated common infrastructure across their three core lines of service (Assurance, Tax, and Advisory) over time. Untangling it requires intimate knowledge of the environment and internal negotiations. Unlike traditional, corporate M&A transactions, acquiring a business from the Big Four requires factoring in this country-by-country negotiation, and consequently, change management, into the deal timeline.
Each country or territory has an equal vote on every decision – from agreeing to the separation, in principle, and the structure of the separation, down to transition service agreements, hardware or software options, service delivery locations, etc. Coming to an agreement with each country or territory can be a Herculean task. Country-specific privacy, security, and independence requirements only add to the complexity. We estimate that it will take about 15-20% longer, on average, than comparably complex M&A transactions.
One of the biggest benefits of the Big Four model has been the synergies it created, minimizing seasonality and revenue variability with three unique lines of service. Separating one or more lines from the whole puts the Big Four’s ability to weather economic headwinds at risk. Buyers also need to factor in incremental sales and marketing costs for building new relationships, fending off increased competition for existing or new business, sustaining current clients and acquiring new logos.
Attempting to carve-out of a Big Four network makes managing security, accessing controls, data and client consents, data and technology migration, technology infrastructure, branding and rebranding, among other challenges, more complex. The time sensitive nature of these transactions needs to be considered carefully when making critical decisions. These operations were not designed for M&A, and over the years, the Big Four have tightly integrated using technology to create a “closed” environment. The buyer, consequently, needs to use the Remain Company for Day 0 and Day 1 activities, which results in higher one-time separation costs.
Valuation Erosion

For Private Equities and other buyers looking to carve-out portions of a Big Four firm, there are many factors to consider while developing the valuation model – the structuring of the Sales Purchase Agreement (SPA), the cost to separate and stand-up an independent entity, TSA arrangements, and operational investments needed to run a truly global and independent organization.
Prospective investors would do well to think through:
Acquirers should expect much higher one-time separation costs, and longer time to close given the regulatory, structural, and infrastructural complexities. Getting third parties to handle separation depends heavily on support from the Parent Company, who will charge a premium for it. Similarly, simplifying the Network-of-Firms business model into a single firm requires significant management, and Private Equity mindset reinforcement, to get all the territories to buy in and implement the New Company vision, while ensuring strict adherence to time-consuming independence requirements and complying with dozens of regulatory bodies. All said and done, success depends heavily on the New Company’s ability to develop synergies beyond the Big Four’s ideas, personnel and processes, so they can create a collective, new vision for the future.
While there are several challenges, significant value can be generated by separating Big Four Consulting and Advisory services from the Assurance or Tax businesses. Specifically:
Value Capture

The limitations of the Big Four’s current operating structure are significant, but not unsurmountable, challenges for the acquirer. Carving-out the business lines on a global scale requires different considerations, from the due diligence to the value capture stages of the transaction, to deliver investor value. That said, the prospect of carving-out a business line from the Big Four presents considerable opportunities for Private Equities.
