How FDD analysts read a food and beverage business: gross margin and input-cost volatility, trade spend, shelf-life obsolescence, retailer concentration and QoE.
A food and beverage business looks deceptively simple. People buy things, eat them, buy more. But the margin between a healthy branded producer and a value-destroying one is thin, volatile and buried in places the headline P&L never shows you. Input costs swing on a bad harvest. Half the revenue line is quietly funded by payments back to the supermarket. Inventory has a use-by date stamped on it. If you run a generic Quality of Earnings playbook over an F&B target without adjusting for the sector, you will miss the very items that decide whether the multiple is defensible. This piece walks through what actually matters when you diligence a food or drink producer, and how to talk about it in an interview.
Most of what you learn in a general QoE 101 primer holds here: normalise EBITDA, understand the revenue base, build a defensible net debt and working capital picture. The difference is where the risk concentrates. In an F&B manufacturer, three forces dominate everything else:
Get those three right and you understand 80% of the deal. The gross margin bridge, not the EBITDA line, is where an F&B QoE lives or dies.
The first thing to build is a gross margin walk across the review period, decomposed into volume, price and cost. In a stable services business you might skip this. In F&B you cannot, because a flat gross margin percentage often hides two large forces cancelling each other out: a commodity spike absorbed by a price increase that customers have not fully accepted yet.
You are trying to answer one question: is the historical margin sustainable, or is it a snapshot of a favourable point in the commodity cycle? A dairy business that earned 34% gross margin in a year when milk prices were unusually low is not a 34% margin business. The buyer will own it through the next upswing.
Practical checks:
A stable gross margin percentage across a period of violent commodity movement is not reassuring - it is a question. Either the business has genuine pricing power, or it is riding a hedge, a mix change or a one-off supplier deal that will not repeat. Find out which before you trust the number.
Here is the item that separates people who have done an F&B deal from people who have not. Trade spend - also called promotional allowances, trade promotions or customer investment - is the money a producer pays retailers to run price promotions, feature products in a leaflet, secure end-of-aisle displays or hit volume targets. In a consumer branded business it can run to 15–25% of gross sales. It is enormous, it is judgemental, and it is frequently the single largest accounting soft spot in the whole target.
The accounting problem is twofold. First, classification: some producers net trade spend against revenue (correct under IFRS 15 for most promotional payments, which are variable consideration), while others park parts of it in cost of sales or even operating expenses, which flatters the reported gross margin. Second, cut-off and accrual: trade spend is accrued based on estimates of what promotions customers will claim. Under-accruing the promotional liability at period end pulls profit forward; catching up later creates a "surprise" cost the following year.
What you do about it:
The table below shows a simplified branded snack producer. Watch how a "£4.0m EBITDA" business becomes a very different number once trade spend is treated properly and an under-accrual is corrected.
| Line | As presented (£000) | Adjustment (£000) | Adjusted (£000) | Note |
|---|---|---|---|---|
| Gross sales | 40,000 | - | 40,000 | Invoiced value |
| Trade spend (promotions, rebates) | (6,000) | (900) | (6,900) | Closing accrual understated vs 17.25% run-rate |
| Returns & listing fees | (1,200) | - | (1,200) | |
| Net revenue | 32,800 | (900) | 31,900 | The real top line |
| Cost of goods sold | (22,000) | - | (22,000) | |
| Gross profit | 10,800 | (900) | 9,900 | Margin 33% → 31% |
| Operating costs | (6,800) | - | (6,800) | |
| Reported EBITDA | 4,000 | (900) | 3,100 | |
| Add back: owner's excess salary | - | 400 | 400 | Normalisation |
| Adjusted EBITDA | 4,000 | (500) | 3,500 | Basis for the multiple |
The takeaway: the £900k trade-spend under-accrual is worth more than a full turn of EBITDA at any realistic multiple. A buyer paying 8x would have overpaid by roughly £7.2m on that single item had it gone unchallenged. This is why trade spend earns its own workstream, and why it dovetails with a proper reading of revenue quality.
F&B inventory is not a warehouse of durable widgets. It has a use-by or best-before date, so a portion of it is always ageing toward zero value. Your job is to assess whether the obsolescence provision reflects reality.
Obsolescence also flows into working capital. A business carrying slow-moving stock has overstated its working capital investment, which matters when you agree the peg. This is exactly the kind of judgement that belongs in a serious net working capital analysis rather than being taken at face value.
Almost every F&B business is seasonal - ice cream in summer, confectionery at Christmas, drinks around events. Seasonality distorts two things: the run-rate you extrapolate from, and the working capital target.
If you look at a single balance-sheet date you will get a misleading picture of normal working capital. A confectioner on 31 December is drained of stock and flush with receivables; the same business in September is stuffed with inventory it built ahead of the peak. You must build a monthly average working capital profile across at least 24 months to set a fair peg, and a buyer who agrees a completion-date snapshot on a favourable month will overpay. This is central to how a working capital target is negotiated.
| Month | Inventory (£000) | Receivables (£000) | Payables (£000) | Net WC (£000) |
|---|---|---|---|---|
| March (trough) | 2,100 | 3,400 | (2,900) | 2,600 |
| September (build) | 5,800 | 3,100 | (4,200) | 4,700 |
| December (peak sell-through) | 1,900 | 5,600 | (2,700) | 4,800 |
| 12-month average | 3,300 | 4,000 | (3,300) | 4,000 |
Pegging on March's £2.6m rather than the £4.0m average would hand the seller roughly £1.4m of value at completion - the buyer funds the seasonal build with no compensation.
Whether the target sells its own brand or manufactures private label for retailers changes the risk profile entirely, and a business that does both needs the two analysed separately.
Model the two streams apart, and stress-test what happens to fixed-cost absorption if a major private-label contract is lost. This is where the sector-specific work meets classic customer concentration analysis.
In branded and private-label F&B alike, the customer base is the grocery retailers, and it is brutally concentrated. In some markets three or four chains represent the overwhelming majority of a producer's sales. That creates several linked risks:
Quantify the concentration, map the contract renewal dates, and read the actual supply agreements for termination and delisting clauses. A red-flag concentration profile can cap the multiple regardless of how good the margin looks - a theme that runs through the general red flags in FDD work.
Interviewers love F&B because it tests whether you can move past textbook QoE into commercial judgement. A typical prompt: "You're diligencing a branded biscuit maker. Reported EBITDA is £8m. Where do you focus?"
"I'd start with the gross margin bridge, because in food and drink the cost base moves with commodities and I want to know whether £8m sits on a normal point in the cycle or a favourable one. I'd rebuild margin by product family and overlay wheat, sugar and energy indices against cost of sales, and I'd check whether any hedge is flattering the current period and due to roll off. Then I'd go straight to trade spend - in a branded biscuit business it could easily be 15 to 20% of gross sales, so I'd move to a net revenue view and rebuild the promotional accrual to test whether the closing liability matches historical claim rates. An under-accrual there can be worth more than a full turn of EBITDA. On the balance sheet I'd age the inventory by remaining shelf life and check the obsolescence provision, and I'd build a monthly working capital profile because biscuits are seasonal around Christmas and I don't want to peg on an unrepresentative month. Finally I'd size customer concentration across the major grocers, map contract renewals and read the listing agreements for delisting clauses. My deliverable would be an adjusted EBITDA that strips out the hedge benefit and any accrual catch-up, plus a clear view on whether the margin and the top customers are sustainable."
That answer works because it names the sector-specific items in priority order and ties each back to value. If you want a structured way to rehearse this kind of response, the TS interview preparation plan is built for exactly this.
Food and beverage rewards the analyst who reads the P&L from the bottom up: net revenue after trade spend, a gross margin bridge that respects the commodity cycle, inventory valued against the calendar on the packaging, and a working capital peg that survives the seasons. Do that, and the EBITDA you present is one a buyer can actually stand behind. Skip it, and you are pricing biscuits at the wrong point in the harvest. In this sector, the value is in the deductions - the money paid back to the retailer, the stock that expires and the margin that only exists at a lucky moment in the cycle. Find those, and you have found the deal.
