Deal structuring: earnouts, representations & price adjustments

When Microsoft closed its $68.7 billion acquisition of Activision Blizzard in October 2023, **the final price was actually $750 million *lower* than the headline figure announced two years earlier**, not because Microsoft renegotiated, but because the deal's structure included specific adjustments for cash, debt, and working capitalworking capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → movements during the unprecedented 21-month regulatory delay. That $750 million swing, roughly the GDP of Liechtenstein, is the difference between an average CFO and a great one. It lives entirely in the deal mechanics that most boards don't read carefully enough.

In 2026's deal environment, with interest rates still elevated above pre-pandemic norms, valuation gaps between buyers and sellers at decade-highs (Bain's 2026 M&A Report shows a 23% bid-ask spread in mid-market deals), and OECD Pillar TwoOECD Pillar TwoOECD-backed rules imposing a 15% minimum effective tax rate on large multinational groups, jurisdiction by jurisdiction.View full definition → reshaping cross-border tax structuring, the CFO who masters deal structuring captures value that no synergy model can replicate.

The three pricing mechanisms every CFO must master

Before negotiating earnouts or insurance, the CFO must decide how the *purchase price itself* moves from signing to closing. This single choice can swing final consideration by 5-10% of enterprise value.

Locked-box vs. completion accounts

The completion accounts mechanism, dominant in U.S. deals, calculates the final price at closing based on actual cash, debt, and working capital. The seller delivers, the buyer counts, and adjustments flow 60-90 days post-close. The risk: post-closing disputes. KPMG's 2025 M&A Dispute Survey found that 41% of completion accounts deals trigger a price dispute, with an average swing of 3.2% of EV.

The locked-box mechanism, preferred in 78% of European deals per CMS's 2025 European M&A Study, fixes the price at a historical balance sheet date (typically the last audited year-end). The seller bears no closing-date risk; the buyer pays "interest" (a daily ticker, usually 4-6% in current rate environment) from locked-box date to closing. The seller commits to "no leakage", no dividends, related-party payments, or unusual transactions between locked-box date and closing.

When CVC acquired The Authentic Brands Group stake in 2024, the locked-box mechanism, set against December 31, 2023 accounts, saved an estimated 90 days of post-closing audit work and eliminated a contentious working capital negotiation. The trade-off: CVC had to get comfortable with a balance sheet that was eight months old at signing.

The CFO's decision rule: Use locked-box when the target has clean audited accounts, stable working capital, and the seller is a sophisticated PE house. Use completion accounts when the target is carve-out, has volatile working capital, or audited financials are stale.

The working capital trap

Even in completion accounts deals, the working capital "peg", the normalized level above which excess cash flows to the seller and below which the buyer claws back, is where deals are won and lost. The standard methodology averages 12 months of monthly working capital. But seasonal businesses get murdered by this.

When Kraft Heinz acquired several smaller brands in 2024, then-CFO Andre Maciel restructured working capital pegs to use a 24-month seasonally-adjusted average, capturing roughly $40 million in value that a naive 12-month average would have transferred to sellers. The lesson: the peg methodology, not just the headline EV, is where CFO scrutiny pays off.

Earnouts: the negotiation tool that bridges valuation gaps

In 2026's environment, earnouts appear in 34% of private deals, up from 19% in 2021, according to SRS Acquiom's 2026 Deal Terms Study. They're the structural answer to the bid-ask spread problem: sellers believe in their forecasts, buyers don't, and earnouts let both sides bet on the truth.

But earnouts are also where the most litigation happens. The Delaware Court of Chancery handled 47 earnout disputes in 2025 alone. Why? Because the metric, the measurement period, and the operational controls during the earnout period create endless ambiguity.

Designing an earnout that actually works

The Bristol-Myers Squibb acquisition of Celgene in 2019 included a CVRCVRThe percentage of visitors or prospects who complete a desired action (purchase, sign-up, contact form), calculated as conversions divided by total opportunities.View full definition → (contingent value right) tied to FDA approval of three specific drugs by specific dates. When one drug missed its March 2021 deadline by months, $6.4 billion in CVR payments evaporated. Celgene shareholders sued. They lost, because the milestones were drafted with surgical precision: specific drug, specific indication, specific date, specific regulatory action.

That's the gold standard. Contrast it with the typical "EBITDAEBITDAEBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) measures a company's operating profitability before financing and accounting decisions, used to compare core performance across firms.View full definition → earnout", pay 5x incremental EBITDA over a $50M baseline for three years post-closing. Sounds clean. It isn't. Whose EBITDA definition? Allocated corporate costs? New product investments? Acquisitions the buyer makes that boost the target's reported EBITDA?

The CFO's earnout checklist:

1. Prefer revenue or operational metrics over EBITDA. Revenue is harder to manipulate. Better still: customer count, regulatory milestones, product launches.
2. Define accounting policies explicitly, don't say "in accordance with GAAPGAAPThe standard set of accounting rules companies follow to prepare consistent, comparable financial statements, dominant in US reporting.View full definition →." Say "applying the accounting policies set forth in Schedule 4.7."
3. Cap and floor the earnout. Unbounded earnouts create perverse incentives.
4. Address operational covenants. Will the buyer be required to "use commercially reasonable efforts"? Or can it integrate, restructure, and reallocate freely?
5. Shorter is better. 12-24 months. Three-year earnouts almost always end in dispute.

Representations, warranties & the rise of W&I insurance

The reps and warranties section of an SPA is 60-80 pages of the seller telling the buyer what's true. Title to assets, no undisclosed litigation, tax compliance, environmental matters, IP ownership, employee benefits. Every rep is a potential claim if it turns out to be false.

The traditional structure: the seller escrows 10-15% of purchase price for 12-24 months. Buyer makes claims. Lawyers fight. Sellers, especially PE sellers desperate for clean exits, hate this.

Enter Warranty & Indemnity (W&I) insurance, now standard in roughly 65% of European deals and 50% of U.S. deals above $50M EV. The insurer takes the risk, the seller walks away clean, and the buyer gets a deeper-pocketed counterparty.

In 2026, W&I pricing has shifted dramatically. After a soft market in 2021-2022 (premiums of 0.7-1.0% of policy limit), 2025 saw rates rise to 1.4-1.8% as insurers absorbed claims from the 2021 deal vintage. Current expected loss ratios are running at 19% across major underwriters, the highest in a decade.

When W&I pays off

Brookfield's 2024 acquisition of Network International included a $35M W&I policy that paid out within 14 months on a tax matter the seller's diligence had missed. Total premium: roughly $490K. Net benefit to Brookfield: north of $30M, plus zero litigation overhead.

But W&I has gaps.

The CFO must layer specific indemnities, kept with the seller, over the W&I policy for these gaps.

Putting it together: the "project horizon" case

Consider a composite case based on three 2025 mid-market deals. "Horizon Industrial", a $480M EV carve-out from a European conglomerate, sold to a U.S. strategic acquirer. The CFO of the acquirer faces:

• Seller demands $480M, locked-box at June 30, 2025
• Forecasts show $52M EBITDA in 2025, with the seller projecting $68M by 2027
• Three customer contracts (representing 31% of revenue) are up for renewal in 2026
• The carve-out involves shared IT systems and a TSA (Transition Services Agreement)
• A pending environmental remediation at a German site has uncertain cost ($5M, $25M range)

The naive structure: pay $480M, take W&I insurance, close. The CFO who structures well does this instead:

Headline price: $420M (locked-box at June 30, 2025), with ticker interest of 5.5% per annum to closing.

Earnout: up to $80M, payable in two tranches:

• $40M if 2026 revenue exceeds $245M (tied to customer renewal success)
• $40M if 2027 EBITDA exceeds $62M, with EBITDA defined in a 14-page schedule

Specific indemnity: Seller retains 100% liability for the environmental remediation, uncapped, surviving 10 years. Not insurable, must be seller-backed with a $20M parent guarantee.

W&I insurance: $48M limit (10% of EV), 0.5% retention, premium ~$770K, covering general reps for 24 months and fundamental/tax reps for 7 years.

TSA pricing: Cost-plus-7%, with declining service commitments over 18 months and break fees if buyer terminates early.

The structural result: the buyer's day-one cash outlay drops from $480M to $420M. The seller has skin in the game for the customer renewals and EBITDA growth they promised. Environmental tail risk stays with the party that created it. W&I covers unknown risks at a fraction of the historical escrow opportunity cost.

If the business performs as the seller forecasts, total consideration reaches $500M, a premium to headline. If it underperforms, the buyer paid $420M for an asset worth $420M. Both sides win in their respective scenarios. *This* is structuring.

The tax layer: pillar two changes everything

Any 2026 deal structuring discussion must address OECD Pillar Two, now in force across the EU, UK, Japan, Canada, Australia, and 35+ other jurisdictions. The 15% global minimum tax has rendered obsolete several classic structures:

• IP migration to low-tax holdcos, largely neutralized
• Debt push-down to high-tax jurisdictions, still works but interest deductibility caps (ATAD III in Europe, Section 163(j) in U.S.) limit benefit
• Tax step-ups in asset deals, still valuable, but model the GloBE (Global Anti-Base Erosion) impact carefully

The practical CFO move in 2026: model both the pre-Pillar Two and post-Pillar Two effective tax rate of the combined entity. Deals that looked accretive on a 22% blended ETR may be 280-400bps less accretive at the 15% floor, particularly if the target has historically used IP regimes in Ireland, Switzerland, or Singapore.

The CFO's action checklist

1. Map the pricing mechanism to the asset. Locked-box for clean, audited, stable targets with sophisticated counterparties. Completion accounts for carve-outs, volatile working capital, or unaudited targets. Negotiate the working capital peg methodology with the same intensity as the headline EV, it's a 3-5% l
