The working capital adjustment: how 5% of headline price quietly disappears

A founder closes a sell-side deal at ₹500 crore headline. The SPA has a working capital target of ₹62 crore. Trailing 12-month working capital, on the seller's calculation, sits at ₹50 crore. The ₹12 crore gap comes off the cash at closing.

The founder's bank balance reads ₹488 crore. The headline price was real; the cash was not.

This is the working capital adjustment doing exactly what the buyer designed it to do. Sometimes legitimate, sometimes manipulative, often both. Worth understanding the mechanics — because the number is recoverable if you fight it at the right moment.

What the working capital adjustment is

Every M&A deal has a working capital mechanism. The buyer is paying for a business that comes with operating assets and liabilities — receivables, inventory, payables, accrued expenses. These items move daily. The buyer wants the business delivered with a normalised working capital base; the seller doesn't want to leave excess cash on the table.

The mechanism: agree a target working capital amount in the SPA, calculated as the trailing 12-month or 24-month average. At closing, calculate the actual working capital. Difference settles cash — if actual is above target, seller receives the excess; if actual is below target, buyer reduces the closing payment.

In theory, this is neutral. In practice, the target is where the negotiation happens, and the buyer has a structural advantage in setting it.

How buyers sandbag the target

Sandbagging is industry slang for setting the working capital target artificially high. The mechanics vary, but the patterns are consistent.

Method 1: Use a period that includes a seasonal peak. Working capital fluctuates with the business cycle. A consumer brand carries higher inventory pre-festival, lower post. A B2B services business carries higher receivables before March-end book-closing pressure. If the trailing 12 months end in the seasonal peak, the average is inflated.

Buyer fix: use trailing 12-month period ending at closing date.

Seller fix: insist on a seasonally-adjusted 24-month average, or specifically exclude defined peak quarters.

Method 2: Define working capital broadly. Standard definition: current assets less current liabilities. But which assets? Includes inventory, but at gross or net of provisions? Includes deferred tax assets? Includes prepaid expenses? Different inclusions can shift the calculation by 5-10%.

We have seen buyer-drafted SPAs include items like 'finished goods at standard cost including allocated overhead' (inflates inventory and therefore working capital) and exclude items like 'deferred revenue' (which should reduce working capital because it represents cash received against future services).

Method 3: Treat normalised items as part of working capital. One-off receivables (a large customer payment that's not recurring), one-off inventory build (raw material stockpile before a price increase), trade discounts not yet adjusted. The buyer includes these in trailing working capital, inflates the target, and then excludes the same items from closing working capital because they've normalised.

Method 4: Pick a moment in time, not an average. Some SPAs measure target as 'working capital on the date 12 months prior to signing'. A single point in time is volatile and easy to manipulate.

The pre-LOI fight

The single most leveraged moment to negotiate working capital is at LOI, before exclusivity. Most sellers don't because they don't realise it matters yet.

At LOI, the buyer's deal team is still selling the deal internally. They don't want to lose the asset to a competing bid over a 2-3% structural issue. They will agree to defined working capital methodology in the LOI in ways they won't at SPA.

The LOI should specify:

(a) Calculation period. Trailing 12 months ending at closing date, with monthly averages used to compute the trailing average. Not point-in-time, not period ending at a fixed historical date.

(b) Components included and excluded. Specifically list what's in (trade receivables net of provisions, raw material inventory, finished goods at lower of cost or net realisable value, trade payables) and what's out (one-off items, deferred tax, cash and equivalents).

(c) Seasonality adjustment. If the business is materially seasonal (consumer brands, agri, hospitality), the SPA must adjust for it. Most clean methodology: 24-month average rather than 12-month.

(d) Working capital expert. Disputes are referred to a neutral working capital expert — typically a senior Big Four partner — whose decision is binding within a defined timeline (usually 30-45 days).

Sellers who get (a)-(d) into the LOI lose 0.5-1% in working capital adjustment on average. Sellers who leave it for SPA negotiation lose 3-5%.

The seasonality trap

We have run sell-side processes for consumer brands where 60-70% of annual sales happen in October-December. Working capital peaks in August-September (raw material build for the festival season) and troughs in February-March (post-season inventory liquidation).

The buyer's first SPA draft uses trailing 12 months ending September. The seller's actual closing working capital is calculated as of February. The buyer is comparing the trailing peak average to the post-season trough — a structural mismatch that costs the seller 6-8% of working capital before any business issues.

Fix: 24-month average, computed monthly, with the average matched to the same calendar position as closing. Or even simpler: if closing is in Q4, the target is the Q4 average of the prior two years. The Big Four advisor on the seller side should build this model and have it ready at LOI.

The collar and the floor

Even with a fair target, working capital at closing can swing. A surprise customer payment delay, an inventory write-down, a seasonal cash crunch — actual working capital can deviate from target by 5-10% in either direction for legitimate reasons.

Sellers should negotiate a working capital collar — a dead band where small deviations don't trigger price adjustments. Typical: ±2% of target. Deviations within the collar don't move closing cash. Deviations outside the collar move closing cash dollar-for-dollar.

Floor protection: a maximum working capital adjustment. The total adjustment cannot exceed, say, 3% of headline price. This caps the seller's downside if a working capital dispute spirals.

Buyer pushback: collars and floors limit the buyer's downside protection. The negotiation is real and usually settles at ±1% collar and 5% cap. Worth pushing for both.

The Big Four advisor on your side

Most sellers use the buyer's QoE numbers as a starting point. This is a mistake. The buyer's QoE is built to support the buyer's working capital target.

What sellers should do: engage a Big Four advisor on the sell-side to build a vendor working capital analysis at the start of the process. The analysis should establish, in advance:

Trailing 12 and 24-month working capital, calculated under the seller's accounting policies, with monthly granularity.

Seasonality decomposition: which months drive the variation, which are recurring vs one-off.

Normalisation adjustments: items the buyer might claim are non-recurring (and should therefore be excluded from target).

Closing-period forecast: what working capital is expected to be at the planned closing date, and what the variance to target would look like under different methodologies.

This pre-emptive analysis arms the seller in two ways. First, it sets a defensible target the seller can anchor to. Second, when the buyer's QoE arrives, the seller has independent analysis to counter-propose against — not just disagreement.

We have seen sellers recover 50-70% of working capital sandbagging through pre-emptive Vendor WC analysis. The cost (₹15-30 lakh in advisor fees) is dwarfed by the recovery (₹3-8 crore on a mid-market deal).

The acquisition accounting reality

Worth noting why buyers care so much. The working capital adjustment is the single largest non-price lever in M&A. On a ₹500 crore deal, a 1% working capital swing is ₹5 crore in cash. The deal team gets credit internally for landing the working capital favourable. Bonuses are sometimes tied to it.

The seller's deal team — internal CFO, external banker, external counsel — should treat working capital with the same seriousness. We have seen sell-side teams celebrate a 1x EBITDA multiple uplift while losing 5% of headline price in working capital. Net effect: zero.

What we do at engagement

Four-step workflow:

Step 1: Build the Vendor WC analysis at pre-LOI stage. 24-month monthly working capital, seasonality decomposition, normalisation schedule.

Step 2: Negotiate the working capital methodology into the LOI. Period, components, seasonality, expert.

Step 3: Track buyer's QoE in real time. When the buyer's working capital target lands in the SPA, we compare it against our Vendor WC analysis and identify each discrepancy.

Step 4: Negotiate the discrepancies item by item. Most buyer adjustments don't survive direct technical challenge. The ones that do, we negotiate as collar items or specific exclusions rather than baseline target changes.

The headline price is the negotiation founders pay attention to. The working capital target is the negotiation that decides how much of the headline price actually arrives in the bank account. The first is loud and visible. The second is quiet and structural. The second is where 3-5% goes.

What ready looks like at closing

By closing, the seller should have: (a) a fully reconciled working capital calculation under SPA methodology, with monthly history attached, (b) a closing-period forecast filed with the buyer 10 days before closing for joint review, (c) a working capital expert nominated and pre-engaged, ready to arbitrate any dispute within 30 days post-closing.

Anything less and the seller is negotiating from defensive ground for 60-90 days post-close, when the headline deal is done and the leverage is gone.
