Why sell-side M&A processes fail in India: the five reasons we keep seeing

Roughly one in five sell-side processes we see in the Indian mid-market does not close. The reasons are not random. They cluster around five patterns that are visible early — sometimes at the buyer-list stage, often by the management presentation, almost always before the LOI is signed.

Worth knowing the patterns. Founders who recognise them stop deals before they become expensive failures. Founders who don't recognise them spend six to nine months and ₹3-5 crore in advisor fees discovering them the slow way.

Reason 1: Diligence reveals undisclosed problems

The single most common failure pattern. The seller goes to market with an information memorandum that paints a clean picture. Diligence finds the gap between the IM and the reality.

What this looks like in practice. A B2B services company shows top-3 customer concentration of 28%. Diligence finds it's 42% once white-labelled revenue is correctly attributed. The IM said the customer base was diversified; the data doesn't support it.

A consumer brand shows 18% EBITDA. Diligence finds the EBITDA includes a recurring marketing spend the founder treats as 'investment' but the buyer treats as opex. Normalised EBITDA: 11%. Multiple haircut: 30%.

A technology platform shows ₹15 crore of recognised revenue from large customers. Diligence finds the revenue was recognised on contract signing rather than service delivery. Under buyer's accounting, ₹8 crore reverses out. Revenue restated.

The pattern: the founder isn't lying. The founder is presenting the business through the lens that makes the business look best. Diligence applies a different lens. The gap surfaces, and the deal either re-prices or dies.

How to prevent: vendor due diligence. Run a Big Four QoE on the business before going to market. The findings will be uncomfortable. Fix what's fixable, disclose what isn't. The IM and data room then reflect a defensible position, not an optimistic one. Costs ₹50-80 lakh. Saves the deal at a 5x multiple of the cost when it works.

Reason 2: Regulatory delays

Indian M&A has more regulatory touch-points than most jurisdictions. FDI sectoral approvals, CCI notification, FEMA pricing certificates, RBI for NBFC transfers, IRDAI for insurance, SEBI for listed targets, sectoral regulators for telecom/aviation/defence/media.

Each touch-point has timelines that the seller's optimistic plan ignores. CCI Phase I takes 30 working days (six weeks elapsed). CCI Phase II adds 210 working days (ten months). FDI approval route adds 8-16 weeks. RBI sectoral approval adds 6-12 weeks. Sectoral regulators add 4-12 weeks depending on the sector and the complexity.

What founders underestimate. A deal that looks like it can close in 60 days signing-to-closing turns into 180 days when CCI requests additional information mid-Phase I. The buyer's funding may be committed, but a foreign LP's reserve allocation is time-sensitive. Or the buyer's currency hedge expires and the rupee moves 4%. Or the buyer's investment committee shifts focus to another opportunity.

Indian regulatory drag has killed more deals than founders realise. Not because the regulator denies approval — most do approve, eventually — but because the time between signing and closing creates space for buyer's remorse, market shifts, or financing exhaustion.

How to prevent. Pre-clear regulatory at IOI stage, not at SPA. Engage CCI counsel early to assess whether thresholds are met (Section 5 of the Competition Act — turnover and asset tests, revised in March 2024 with the deal-value threshold). Pre-file informal queries where possible. Map sectoral approvals on the IOI timeline. If the regulatory path adds 90 days, the seller should know on day one, not day forty-five.

Reason 3: Management departure during the process

A sell-side process is a stress test on the senior team. The founder is distracted. The CFO is preparing the data room while running normal close cycles. The COO is fielding diligence calls while running operations. Sales leadership is being interviewed by buyer reps. Some senior people quit.

When the departure is the CFO mid-process, the deal usually survives but at a discount — the buyer questions financial integrity. When the departure is a senior commercial leader, the deal can re-price. When the departure is a co-founder, the deal often dies.

We have seen a CFO resign in week five of a sell-side process. The buyer's QoE was 80% done. The CFO's reasons were unrelated to the deal — personal, valid, irrevocable. The buyer used the departure as a re-trade trigger and reduced the offer by 7%. The seller accepted because the alternative was restarting the process with no CFO, no QoE, and a 5-month gap.

How to prevent. Retention packages signed before the process starts. Specifically: cash retention bonuses tied to closing date for the top 5-8 leaders, with sizes ranging from 6 months' to 18 months' base salary. The cost is real (₹3-8 crore on a mid-market process) but the alternative is worse. Some bankers fold the retention pool into the deal economics as a transaction cost; others bill it separately.

Reason 4: Market shifts mid-process

Indian sell-side processes run 6-9 months end-to-end. Public market multiples can move 20-40% in that window. Sector multiples can compress or expand. Comparable transactions can land at higher or lower numbers than the seller assumed.

The buyer's investment committee re-bases the bid range to current market. The seller's expectation was set 6 months earlier when conditions were different. The gap is sometimes recoverable through structuring (more earn-out, deferred consideration) and sometimes not.

What founders underestimate. The seller psychologically anchors to the IOI number. The buyer's IC, eight months later, has no obligation to anchor anywhere. They underwrite to current market.

How to prevent. Compress the timeline. A 60-day pre-marketing prep, 30 days of buyer outreach, 45 days to LOI, 60 days to signing. Total: 195 days, roughly 6.5 months. Anything longer creates window risk. Sellers who let the process drift to 9-10 months end up renegotiating against a market they hadn't priced.

Secondary prevention: lock in milestone payments at IOI. If the buyer wants exclusivity, the buyer should commit to specific dollar amounts at specific milestones — IOI signing, SPA signing, signing-to-closing. Each milestone reduces the buyer's optionality to walk away cheaply.

Reason 5: Retro-trading on price

The most cynical failure mode and the hardest to recover from. The buyer never intended to pay the IOI price. They used the IOI to win exclusivity and to lock the seller out of other conversations. Eight weeks in, with diligence ostensibly running, the buyer surfaces a series of findings — vague, additive, persistent — and reduces the bid by 8-15%.

Indicators of a retro-trader at IOI stage:

The IOI price is meaningfully above other bids. A buyer bidding 15% above the next-highest bid is either a strategic with a unique synergy case or a buyer who plans to re-trade. Worth asking which.

The buyer's deal team is junior. The IOI is signed by a vice-president or director, with limited partner sponsorship. The seller will be negotiating with someone who has authority to walk but not authority to commit.

Diligence findings are qualitative. A retro-trader's findings cluster around vague concerns — 'management depth', 'customer churn trajectory', 'integration risk' — rather than specific quantifiable issues. Hard to refute because there's no specific number to attack.

The retro lands in week 7-9. Buyer's leverage peaks just before SPA signing. Re-trade lands when the seller's BATNA (restart with another buyer) is most expensive.

How to prevent. Reference the buyer's recent transactions. Have they re-traded on previous deals? Talk to founders of companies they've acquired. The pattern usually shows up.

Pre-LOI: structure the LOI with deposit (₹2-5 crore in escrow, refundable only on specific named conditions), narrow CP list, and short exclusivity (45 days, not 90). The seller should price the option the buyer is asking for.

Mid-process: if the buyer's diligence questions cluster around qualitative concerns, escalate. Request a written summary of issues from the buyer's investment committee. A real concern will be backed by numbers; a retro-trade gambit usually won't.

Twenty percent of sell-side processes fail. Eighty percent of failures cluster around five patterns. Each pattern is visible early. The sellers who don't fail are the ones who recognise the pattern and act on it before it crystallises.

The honest version

Worth saying plainly. Some deals should not close. A buyer who finds real diligence issues and walks is not the failure — the deal was wrong. A regulatory environment that doesn't allow the transaction is not a failure — the structure was wrong. A market shift that re-prices the asset is not a failure — the timing was wrong.

The failures we treat as preventable are the ones where the seller could have foreseen the issue and didn't. Vendor due diligence that surfaces problems early. Retention packages that hold the team. CCI pre-clearance that maps the regulatory path. LOI structures that price the buyer's optionality.

Each of these costs money upfront. Sellers without bankers usually skip them. Sellers with bankers sometimes still skip them, depending on the banker.

What we run at engagement start

Three-week pre-marketing window. Week 1: alignment between founder and board on outcome, retention package for senior team, regulatory pre-clearance plan. Week 2: vendor due diligence kickoff (QoE, legal, tax). Week 3: IM, teaser, data room, buyer list with archetype distribution.

Then 30 days of outreach. Then LOI. Then 60 days to signing. Then 30-90 days to closing depending on regulatory.

Eight months from kickoff to cash in the bank, run cleanly. Twelve months when something slips. Eighteen months when two things slip. Each slipped milestone increases the failure probability by 5-10 percentage points.

Sellers who treat the pre-marketing window as the cheap part of the process underinvest in the most leveraged 21 days of the deal. Sellers who treat it as the deal-defining window run cleaner processes and close at higher percentages of the headline price.
