Case 014Stock pitch and thesis defenceCore
Pitch a trucking company on operating leverage: revenue Rs 3,000 crore, fixed costs Rs 600 crore, variable costs 70% of revenue. If revenue rises 15%, what happens to operating profit, and how do you answer when the interviewer attacks each assumption?
1The situation
You pitch Sarathi Freightways, a road freight company, as the interesting company you have looked at recently. Revenue is Rs 3,000 crore. Fixed costs, depots, owned trucks, head office and salaried staff, are Rs 600 crore a year. Variable costs, fuel, tolls, drivers' trip pay and hired trucks, run at 70% of revenue.
Your thesis: a manufacturing upcycle will lift Sarathi's revenue by 15% next year. The interviewer asks for the profit impact, then attacks every assumption you made.
2Your task
What does a 15% rise in revenue do to operating profit, and how do you defend the number under attack?
Quick check
Revenue rises 15%. What happens to Sarathi's operating profit?
Worked solution
Try it on paper, then open one step at a time.
30-second answerThe answer to give first
Operating profit rises 45%, from Rs 300 crore to Rs 435 crore. Each rupee of revenue contributes 30 paise after variable costs, and fixed costs do not move, so contribution of Rs 900 crore on a profit of Rs 300 crore gives operating leverage of 3. The defence is to show which assumption each attack changes and by how much, and to say first that the same leverage cuts profit 45% if revenue falls 15%.
Step 1Why does profit move three times as fast as revenue?
Because a fifth of Sarathi's costs do not change with the work it does. The degree of operating leverageHow much operating profit changes for a given change in revenue: contribution divided by operating profit. is contribution over profit: Rs 900 crore over Rs 300 crore, 3 times. A wedding caterer who owns the kitchen and pays the chefs a salary works the same way: the tenth wedding of the month costs only food and serving staff, so almost all of its fee is profit, and a month with two weddings fewer is painful for the same reason.
Step 2What do you say before the interviewer attacks?
Volunteer the downside. If revenue falls 15% instead, operating profit falls to Rs 165 crore, down 45%, and revenue of Rs 2,000 crore, a third below today, wipes it out. A pitch built on operating leverage is a pitch on the direction of revenue, and saying so first shows the interviewer you understand the instrument you are using rather than just the upside it produces.
Step 3How do you answer each attack?
Treat each one as a change to one input and give the new number. An attack is a request for a sensitivity, and the strongest reply is a figure, not an adjective. Fixed costs are not fixed: if 15% more freight needs Rs 60 crore of extra depots and trucks, profit rises to Rs 375 crore, 25%. Diesel rises and variable costs go to 72%: Rs 366 crore, 22%. The growth is price, not volume: then costs barely move and profit could rise far more, which is the upside to test with the company's contract terms.
| Attack | What changes | Operating profit, Rs crore | Growth |
|---|---|---|---|
| Base case | Revenue +15% | 435 | +45% |
| Fixed costs step up | +Rs 60 crore of depots and trucks | 375 | +25% |
| Diesel costs more | Variable costs 72% of revenue | 366 | +22% |
| All growth is price | No extra variable cost | 750 | +150% |
| The upcycle does not come | Revenue -15% | 165 | -45% |
Step 4How do you close the pitch?
Restate the thesis with its condition. Sarathi's profit grows two to three times as fast as its revenue, so the pitch stands or falls on whether the upcycle arrives, and the evidence to watch is freight volumes and truck utilisation month by month. Say what the market already expects if you know it, because operating leverage only makes money for an investor when revenue beats what the price assumes.
Where candidates lose it
Candidates defend every assumption with confidence instead of numbers. When the interviewer says fixed costs are not fixed, the answer is a revised profit figure, not a restatement of the original view.
The second loss is pitching only the upside. Operating leverage is symmetrical; a candidate who does not mention the 45% fall on a 15% revenue drop looks like they found the multiplier and stopped thinking.
What the interviewer asks next
- What would Sarathi's operating leverage be if it hired all its trucks instead of owning them?
- How does operating leverage combine with financial leverage if Sarathi has large interest costs?
- Which line in the quarterly results would tell you first that the thesis is working?
Asked at Wellington Management, Portfolio Management, Boston, 2019 (Wall Street Oasis): The one on one was not like banking with technical's per say, but was more of stock pitch where they grille into that.
