Direct Answer: A price haircut in M&A occurs when the purchase price is reduced below the number agreed in the Letter of Intent, typically during due diligence. The most common causes in technology M&A fall into two categories: quantitative adjustments — net working capital shortfalls, debt-like items including deferred revenue, and indebtedness — and qualitative adjustments driven by customer risk, key-man dependency, and IP issues discovered during diligence. Understanding these mechanisms before you sign an LOI is the single most effective way to protect your valuation.
Why Price Haircuts Happen
Most founders who experience a price haircut do not see it coming. The LOI felt like the finish line. The number was agreed. The press release was being drafted in their head.
Then diligence started.
Price haircuts are almost never the result of bad faith from the buyer. They are the result of a gap between what the seller believed about their business and what a forensic financial review reveals. Buyers do not create these gaps — they find gaps that already exist. The sellers who avoid haircuts are the ones who found those gaps first.
The mechanisms that drive price haircuts fall into two categories: quantitative adjustments that are calculated mathematically from financial data, and qualitative adjustments that are negotiated based on judgment about risk.
Quantitative Price Adjustments
1. Net Working Capital (NWC) Shortfalls — and Premiums
The working capital peg is one of the most frequently misunderstood mechanisms in M&A, and one of the most common sources of closing-day surprises.
Here is how it works: the purchase agreement establishes a target working capital amount — the level of net current assets the business should deliver at closing to operate normally. This target is set based on historical average working capital, typically calculated over the trailing twelve months. If actual working capital at closing comes in below the target, the purchase price adjusts down dollar for dollar.
Working Capital Peg Example — Price Reduction:
| Item | Amount |
|---|---|
| Agreed purchase price | $25,000,000 |
| Target working capital peg | $2,500,000 |
| Actual working capital at closing | $1,800,000 |
| Working capital shortfall | ($700,000) |
| Adjusted purchase price | $24,300,000 |
Working Capital Peg Example — Price Premium:
| Item | Amount |
|---|---|
| Agreed purchase price | $25,000,000 |
| Target working capital peg | $2,500,000 |
| Actual working capital at closing | $3,100,000 |
| Working capital surplus | $600,000 |
| Adjusted purchase price | $25,600,000 |
The working capital peg is not inherently adversarial. When a seller delivers more working capital than the target, the price goes up. The problem arises when sellers take actions before closing — accelerating collections, deferring vendor payments, or drawing down cash — that artificially inflate closing-day working capital relative to what the trailing twelve-month average would predict. Buyers identify these patterns and challenge them aggressively.
Common reasons closing NWC comes in below peg:
- Seasonal patterns not properly reflected in the peg calculation
- Accounts receivable aged beyond normal collection cycles
- Vendor payments accelerated before signing that created a liability now due at closing
- Pre-closing expenses paid from operating cash that would normally have been in the business at closing
2. Deferred Revenue and Indebtedness
Deferred revenue is one of the most consistently misunderstood items in SaaS M&A, and it is one of the most common sources of unexpected price adjustment.
What deferred revenue is: When a customer pays for twelve months of software access upfront, you collect the cash but have only earned the first month of revenue. The remaining eleven months sit on your balance sheet as deferred revenue — a liability, because you still owe the customer eleven months of service.
Why buyers treat it as debt-like: In a cash-free, debt-free transaction (the standard structure in most M&A), deferred revenue is treated as a debt-like item that reduces the purchase price. The buyer is acquiring the obligation to deliver eleven months of service without receiving additional cash for it. They price this obligation as a reduction to net proceeds.
Deferred Revenue Impact Example:
| Item | Amount |
|---|---|
| Enterprise value agreed in LOI | $20,000,000 |
| Deferred revenue balance at closing | $1,200,000 |
| Deferred revenue treated as debt-like | ($1,200,000) |
| Net proceeds to seller | $18,800,000 |
This adjustment surprises many founders because deferred revenue looks like cash on the balance sheet. It is cash you have already collected — but cash you owe to customers in the form of future service. In M&A, it is a liability, not an asset.
Other debt-like items that reduce proceeds:
| Item | Typical Treatment |
|---|---|
| Outstanding debt and credit facilities | Full deduction |
| Unpaid accrued bonuses and commissions | Deduction for amounts owed at closing |
| Unfunded pension obligations | Deduction |
| Capital lease obligations | Deduction |
| Customer prepayments for services not yet delivered | Debt-like; reduces proceeds |
| Tax liabilities for periods pre-closing | Seller’s obligation; deducted |
| Deferred rent obligations | Deduction in some structures |
Qualitative Price Adjustments
Qualitative adjustments are harder to quantify precisely, which often makes them more contentious than the mathematical adjustments above. They arise from risks the buyer identifies during diligence that were not fully reflected in the agreed valuation.
3. Customer Risk Discovered in Diligence Calls
Buyers conduct customer reference calls as a standard part of technology M&A diligence. The stated purpose is to verify customer satisfaction and product fit. The real purpose is to identify customer concentration risk, product dependency risk, and key-man risk before closing.
What buyers are listening for:
- “We work with you because of [founder name]” — flags key-man dependency; revenue may not transfer
- “We’re evaluating alternatives right now” — flags churn risk not visible in the ARR schedule
- “We’re not using the full product yet” — flags usage risk and expansion assumption problems
- “We’ve had some issues with [specific feature]” — flags product risk that may not appear in NRR data
- “Our contract is up for renewal next quarter” — flags near-term revenue risk not visible at first glance
When customer calls reveal meaningful risk — particularly at customers that represent a significant portion of ARR — buyers have two options: reduce the purchase price to compensate for the risk, or restructure the deal to include an earnout tied to customer retention post-close.
Customer concentration compounds the risk. If your top three customers represent 60% of ARR and one of them expresses ambivalence in a reference call, the buyer has identified a specific, quantifiable exposure. They will not ignore it.
4. IP Issues and Change-of-Control Provisions
Intellectual property issues discovered during diligence are one of the most deal-threatening categories of qualitative risk, and also one of the most preventable.
Common IP issues that drive price adjustments or deal restructuring:
- Unassigned contractor IP: Code written by contractors who did not sign IP assignment agreements. The contractor may technically own the IP they created, leaving the buyer acquiring a product with unclear ownership of core components.
- Open source license conflicts: Use of open source components under licenses that impose restrictions on commercial distribution or require disclosure of proprietary source code.
- Missing invention assignment agreements: Employees who joined before IP assignment agreements were standard practice may have claims to technology they developed.
- Third-party license dependencies: Critical functionality that depends on licenses from third parties that may not be transferable to a new owner without renegotiation.
Change-of-control provisions in customer contracts create a different category of qualitative risk. Many enterprise software contracts include a clause that allows the customer to terminate or renegotiate their agreement if the company is acquired without the customer’s consent. When a significant customer has this clause and the buyer cannot get comfort that the customer will waive it, the contract is treated as at-risk ARR — which is discounted or excluded from the adjusted revenue calculation.
5. Key-Man Dependency
Key-man dependency is the qualitative risk that the business performance depends on the continued involvement of one or two people — almost always including the founder — in ways that create material operational risk post-close.
Buyers assess key-man dependency by examining who has the customer relationships, who is the product decision-maker, who manages the key vendor relationships, and who the engineering team reports to. When the honest answer to most of these questions is “the founder,” buyers see a business that may perform differently under new ownership than it has under the founder’s direct management.
Key-man dependency does not automatically reduce the purchase price — it affects deal structure. Buyers address it through retention packages for key employees, extended earnout periods tied to business performance, employment or consulting agreements that keep the founder engaged post-close, and escrow arrangements that hold a portion of proceeds against post-closing performance.
How to Protect Yourself From Each Risk
| Category | Protective Action | Timeline |
|---|---|---|
| NWC shortfall | Calculate trailing twelve-month average NWC; understand what the peg will be before the buyer proposes it | 6–12 months before process |
| Deferred revenue surprise | Model the debt-like treatment of your deferred revenue balance; understand net proceeds vs enterprise value | Before LOI |
| Customer reference call risk | Know which customers may express ambivalence; address issues proactively; strengthen key relationships before going to market | 12–18 months before process |
| IP issues | Conduct an IP audit; ensure all contractor and employee IP is formally assigned; review open source usage | 12–18 months before process |
| Change-of-control provisions | Review all significant customer contracts; identify which contain change-of-control clauses; assess probability of customer consent | Before engaging buyers |
| Key-man dependency | Build management team depth; reduce concentration of founder relationships; document processes | 12–18 months before process |
Frequently Asked Questions
What is a price haircut in M&A? A price haircut is a reduction in the purchase price below the number agreed in the Letter of Intent, typically resulting from issues identified during due diligence. Common causes include working capital shortfalls, debt-like items such as deferred revenue, customer risk, and IP issues.
What is a working capital peg in M&A? A working capital peg is a target level of net current assets established in the purchase agreement. If actual working capital at closing is below the target, the purchase price adjusts down dollar for dollar. If it is above the target, the price adjusts up.
Why is deferred revenue treated as debt in M&A? Deferred revenue represents cash already collected from customers for services not yet delivered. In a cash-free, debt-free transaction structure, the buyer acquires the obligation to deliver those services without receiving additional cash. This obligation is treated as a liability that reduces net proceeds to the seller.
Can customer reference calls reduce my purchase price? Yes. If customer calls reveal that significant revenue is at risk — due to product dissatisfaction, relationship dependency on the founder, or near-term churn risk — buyers will adjust the valuation or restructure the deal to include an earnout tied to post-close customer retention.
What IP issues most commonly cause price adjustments in tech M&A? Unassigned contractor IP, missing employee invention assignment agreements, open source license conflicts, and third-party license dependencies that may not transfer to a new owner. IP issues discovered late in a process can cause significant restructuring or price adjustment.
Can a working capital adjustment increase my purchase price? Yes. If actual working capital at closing exceeds the target peg, the purchase price adjusts up by the surplus amount. The mechanism works in both directions.
