In today’s rapidly evolving corporate landscape, divestiture advisory has emerged as a strategic imperative for businesses seeking to optimize portfolios and sharpen their competitive focus. A comprehensive approach to divestiture consulting enables boards to make highly informed decisions where portfolio simplification or strategic exits can create meaningful shareholder value. With global divestiture activity rising sharply in 2025 and 2026, driven by heightened market dynamics and activist investor pressure, advisory expertise is no longer a back‑office support function but a board‑level strategic enabler.
Central to effective divestiture outcomes is the role of seasoned advisors who bring analytical depth, execution discipline, and industry insight to complex separation processes. Organizations that engage sophisticated divestiture consulting teams are better equipped to evaluate risk, assess multiple strategic alternatives, and project economic outcomes with precision. In 2025, companies around the world announced more than one trillion U.S. dollars worth of asset sales which marked the highest level of divestiture activity in three years, underscoring the heightened reliance on advisory engagement for these decisions.
What Is Divestiture Advisory and Why It Matters
Divestiture advisory refers to specialized professional guidance provided throughout the lifecycle of a corporate divestment. This process includes identifying non‑core or underperforming business units, evaluating strategic alternatives, preparing assets for sale, executing transactions, and supporting post‑divestiture integration or carve‑out transitions. Unlike traditional M&A advisory, which often focuses on acquisitions, divestiture advisory centers on optimizing portfolios, enhancing shareholder value, and helping boards make structurally important decisions with confidence.
For boards of directors, divestiture decisions are inherently complex. They require balancing financial objectives, stakeholder expectations, regulatory considerations, potential buyer landscapes, and internal capability assessments. Here, the advisory role transcends traditional financial analysis; it incorporates market benchmarking, scenario planning, operational readiness reviews, and strategic positioning. For instance, a 2026 corporate divestiture survey shows a shift toward more creative strategic alternatives, such as joint ventures and multistage separation models, further complicating the decision environment.
Quantitative Landscape: Divestiture Activity in 2025‑2026
The broader M&A market provides a backdrop to divestiture trends. Global mergers and acquisitions saw a significant uptick in the first nine months of 2025, with total deal value increasing by approximately ten percent compared to 2024, reflecting nearly two trillion dollars in transaction value. This expanded deal volume has created parallel momentum in divestiture mandates as corporations reassess their strategic portfolios and consider sales to unlock capital for growth or innovation investments.
Divestiture transactions specifically have been trending upward: Deloitte’s divestiture reports indicate that divestiture deal volume accounted for more than twenty‑five percent of total M&A activity in the third quarter of 2025, up substantially from earlier quarters, while larger transactions over one billion dollars have become a greater proportion of total activity. The magnitude of this trend demonstrates why divestiture advisory is increasingly essential at the board level complex deals warrant thorough preparation and execution oversight.
Market research further quantifies the expanding relevance of divestiture and related advisory services. The global divestiture advisory market was valued at roughly 4.9 billion U.S. dollars in 2025, and is projected to grow at a compound annual growth rate (CAGR) of 14.5% through 2033, approaching an estimated 9.3 billion dollars by the end of that period. Such growth reflects not only increased demand for divestiture services but also the rising complexity and sophistication of corporate separation strategies.
Strategic Drivers Behind Divestiture Decisions
Several key forces are driving the surge in divestiture activity and shaping the role of advisory services:
1. Activist Investor Pressure:
Activist investor engagement has increasingly focused on operational restructuring, asset sales, or corporate break‑ups to unlock shareholder value. In the latter half of 2025, more than half of activist campaigns included demands for mergers, acquisitions, or sales, indicating how divestiture strategies are now a mainstream lever for improving performance. Boards seeking to respond effectively to these pressures are turning to advisory firms to provide defensible analyses and strategic roadmaps.
2. Portfolio Simplification:
Corporations are reassessing sprawling, conglomerate structures in favor of focused business models. Major companies in 2025 including multinational consumer goods and industrial firms announced large‑scale divestitures as part of strategic refocusing efforts. Such decisions require careful valuation, buyer identification, negotiation expertise, and risk management capabilities that advisory teams provide.
3. Regulatory and Market Dynamics:
In an era of evolving regulatory scrutiny and fluctuating capital markets, boards must make decisions with heightened awareness of compliance, timing, and competitive implications. Divestiture advisory teams help interpret regulatory environments, forecast market reaction, and ensure robust execution strategies that withstand external scrutiny.
How Divestiture Advisory Improves Board‑Level Confidence
Delivering confidence to boardrooms begins with establishing clarity around strategic intent and ends with achieving measurable outcomes. Divestiture advisory contributes to board‑level confidence in several essential ways:
Comprehensive Strategic Assessment:
Advisors help boards frame divestiture decisions within the context of long‑term strategy rather than short‑term financial performance. This includes contrasting multiple strategic options, such as full divestitures, partial sales, carve‑outs, spin‑offs, or joint ventures. In 2026, many organizations have shifted toward “always‑on” portfolio evaluation mindsets, though fewer than half of executives are currently conducting reviews multiple times per year.
Rigorous Valuation and Diligence:
Accurate valuation is the cornerstone of any successful divestiture. Advisory teams bring quantitative rigor to financial modeling, scenario analysis, and due diligence, enabling boards to understand the intrinsic and strategic value of business units with a level of precision that supports risk‑adjusted decision making.
Market and Buyer Intelligence:
Understanding potential buyers and market likelihoods is critical. Advisory teams leverage databases, industry expertise, and competitive insights to position assets effectively and identify realistic strategic partners or buyers. This reduces execution risk and enhances transaction certainty.
Execution Discipline:
Divestiture processes are operationally and legally complex. Professional advisory teams coordinate multiple stakeholders, manage deal timelines, address regulatory requirements, and mitigate execution risks—giving boards assurance that implementation will match strategic plans.
Best Practices for Board Engagement
To fully harness the value of divestiture advisory, boards and executives must foster effective collaboration with their advisory partners:
Aligned Strategic Objectives:
Establish clear, shared strategic intent before engaging advisors. Boards should articulate long‑term goals so advisors can craft tailored frameworks and valuation methodologies that match desired outcomes.
Robust Governance Mechanisms:
Boards should implement governance structures that support swift decision making and oversight throughout divestiture planning and execution. Regular checkpoint reviews with advisory teams ensure alignment and transparency.
Scenario Planning and Stress Testing:
Advisors should present not only base‑case forecasts but also alternative scenarios reflecting market volatility, regulatory changes, and buyer behavior. This exercise strengthens board confidence and readiness for unexpected developments.
Integrated Communication:
Clear internal and external communication strategies are essential during divestiture processes. Advisory teams often support boards in shaping messaging to investors, employees, and stakeholders to preserve reputation and maintain business continuity.
Looking Ahead: Divestiture Trends in 2026 and Beyond
The role of divestiture advisory is set to expand even further in 2026 as companies navigate market normalization and evolving strategic imperatives. Boards will continue to rely on advisors not only to execute transactions, but to advise on holistic portfolio management strategies that anticipate industry disruptions and long‑term growth opportunities.
Industry forecasts indicate that corporate divestitures are likely to remain elevated as a portion of overall M&A activity, driven by strategic portfolio realignments and continued shareholder activism. As economies adjust to post‑pandemic realities and technological transformation accelerates, boards that proactively engage with experienced advisory partners will be better positioned to make confident decisions that balance risk with value creation.
The Strategic Edge of Divestiture Advisory
In an environment defined by rapid change, volatility, and rising investor expectations, divestiture advisory plays an essential role in elevating board‑level decision confidence. Organizations that invest in expert divestiture consulting benefit from deeper analytical insight, disciplined execution, and enhanced strategic clarity. Advisory partners help boards assess complex trade‑offs, benchmark against market dynamics, and ultimately make decisions that drive portfolio performance and long‑term shareholder value.
With divestiture activity reaching unprecedented levels across industries in 2025 and early 2026, and with divestiture advisory market growth projected at a double‑digit CAGR over the coming decade, companies that embed these services into their strategic playbooks will gain a measurable edge. Boards seeking to improve confidence, reduce transaction risk, and unlock value in an uncertain global economy should continue to prioritize and integrate divestiture consulting into their highest‑impact governance decisions. As we progress through 2026, the expertise and strategic foresight brought by professional advisory engagements will remain indispensable to corporate leaders navigating complex divestiture landscapes through divestiture consulting frameworks and disciplined execution methodologies.
