Warburg Pincus

The take-home investment memo Warburg Pincus is reported to set against a confidential information memorandum, graded on the ability to synthesize and present, on identifying the merits, on identifying the key risks with the diligence steps that would get comfortable with them, on model integrity and the rationale for assumptions, and on the IRR analysis and choice of sensitivity.

Structure and exercise format are modeled after Warburg Pincus — the take-home memo format the firm is reported to use. The company, the financials and every figure in this case are entirely our own.

Key Concepts

The ideas this case is built on. Know these cold and the case becomes a question of execution rather than knowledge.

The Deal Alert versus the investment memorandum

In a live process there are two memos, written weeks apart. The first is a Deal Alert: two to three pages, written when the book lands, whose job is to get permission to spend money on diligence. The second is the full investment memorandum, written much later before a binding bid — after the data room, after management meetings, after a quality-of-earnings report has come back. Writing the second document from the first document's information makes every page of it decoration, because the things that would fill it are not yet known. The commonest way to fail this case is to produce thirty excellent pages of the wrong document.

One company, three earnings numbers

Reported EBITDA is what the accounts show. Adjusted EBITDA is what the memorandum presents. The earnings you underwrite is a third number, and it is the one every multiple, every turn of leverage and the whole debt quantum should be struck on. A multiple quoted without its denominator is the single easiest thing to be misled by in a sell-side process, which is why a good memo prints all three side by side wherever a multiple appears rather than picking the flattering one.

An adjustment that recurs is not an adjustment

The test on each line of a bridge is whether the cost stops, and what stops it. A monitoring fee that terminates by contract on a change of control stops. The annualized effect of businesses already owned is arithmetic and verifiable. Deal costs, integration costs, severance and greenfield start-up losses at a company that buys four to six businesses a year do not stop, because the plan you are being sold assumes more of the same deals. Calling those exceptional is calling the strategy exceptional.

A plan that buys revenue must charge the cash

When a memorandum states a revenue plan and, separately, an organic growth rate, the difference between them is revenue the plan intends to buy. Buying it costs cash — at the acquired margin and the multiple the company itself discloses — and a plan that shows the revenue without the consideration has shown you the benefit and hidden the price. This is the second-largest thing in the case and it is one subtraction away from two numbers the book prints.

The same benefit sold twice

Watch for a synergy that is both added back to historical earnings as unrealized and embedded in the forecast as margin expansion. Each statement is defensible on its own page; together they charge you for the same improvement in two places. This is the kind of error you only catch by reading a book for internal consistency rather than for content, and it is worth saying out loud in the memo because it changes what the plan is worth rather than merely what it looks like.

Solve for the price, do not pick it

'What is the return at this price?' and 'what would you pay?' are different questions. In this structure the entry price enters in exactly one place — the size of the equity check — so holding the return at the hurdle and inverting gives a closed-form answer rather than a goal seek. And because the output is a ceiling, it truncates to its printed precision: rounding it up, even by a tenth, puts a price on the table the hurdle does not support, which is the one direction that figure is not allowed to move in.

Sensitivities are chosen, not defaulted

The reflex grid is entry price against exit multiple. Here it tests nothing, because the entry price is the output of the exercise and sweeping it against the exit sweeps one variable twice. The two things actually in dispute are how much of the memorandum's bridge survives diligence and where a larger, more diversified business trades on the way out. Choosing the axes is itself a graded judgment, and the choice tells a reviewer whether you understood the case or reached for a template.

Every risk carries its diligence step

A risk list with no diligence attached is a list of reasons to do nothing, and it is the fastest way to look junior on a committee paper. Each risk should name the document, the file or the analysis that would resolve it — three years of monthly management accounts, the pipeline log with the multiple paid on each signed letter of intent, the accreditation body correspondence file. And where a risk cannot be diligenced, say so and price it instead, because a discipline stated is worth more than a diligence item made up.

The memo must be able to say the good things

A Deal Alert that agrees with its own CIM has not done the exercise. But a memo that omits the genuine merits to make its objections look stronger is a worse memo, not a tougher one. Revenue retention, framework coverage, customer diversification and a margin that improves on your own basis as well as the seller's are checkable facts and they belong in the paper. The committee is not asking you to dislike the asset. It is asking whether the price is right.

Frequently Asked Questions

How long should the memo actually be?

Two to three pages, and the cap is the exercise rather than an inconvenience. This is the first investment committee review of a live process: the paper exists to get permission to spend diligence money, not to conclude anything. The thirty-page memorandum belongs weeks later, before a binding bid, when you have had the data room, management meetings and a quality-of-earnings report. Writing it now means most of its pages are decoration, because the facts that would fill them do not exist yet.

Why does the memorandum not contain a price?

Because no memorandum does. The price is what the process is for, and a seller that publishes its own number has made an opening bid and capped itself at it. The same reasoning explains the other omissions: no multiple applied to its own earnings, no capital structure, no return and no recommendation. Those are all the buyer's work, and a book that did them would be arguing with its recipients in advance. The price in this case arrives the way it usually does — verbally, from the advisor, after the book.

Should I take the add-backs at face value?

No, and you should not reject them wholesale either. The memorandum presents all of them without distinction, which is exactly what a memorandum does; the judgment is yours. Test each one on whether the cost stops and what stops it, and be ready to defend the split in both directions. Accepting everything reproduces the seller's answer. Rejecting everything prices the company off reported EBITDA and ignores charges that really do terminate at close. Neither extreme is defensible, and the memo should say which lines moved and why.

The memorandum discloses the multiple the company paid for its own acquisitions. Is that a valuation?

No, and keeping the two apart matters. It is a fact about transactions already completed, on the acquired businesses' earnings at the time, and the memorandum is entitled to disclose it because it describes the economics of the strategy being sold. It is not a view on what this company is worth, and a candidate who anchors on it has been handed a number and mistaken it for an answer. What it is useful for is pricing the acquisitions the plan assumes — and for asking whether an average is hiding a wide spread.

Should I build a discounted cash flow?

No. A first-round Deal Alert prices the asset off what it returns to the fund, not off a cost-of-capital debate, and the hurdle is the discount rate in a sponsor's language. There are no comparable companies and no precedent transactions either — the memorandum contains no peer set to inherit, and a first-round paper that invents one has substituted a screen for the analysis it was asked for. One output price, expressed as a ceiling.

How do I choose the sensitivity axes?

Ask what you might actually lose an argument about. Here it is how much of the memorandum's bridge survives diligence, and where a larger and more diversified version of this business trades when you come to sell it. Do not sweep the entry price: it is the output of the exercise, and running it against the exit multiple sweeps one variable twice while looking like thorough work. Choosing the axes is itself graded, and the choice is the clearest signal in the paper of whether you understood the case.

What does 'every risk gets the diligence step' mean in practice?

It means naming the document or the analysis that would settle it. Not 'we should diligence the add-backs' but a quality-of-earnings review scoped at the specific lines in dispute, with three years of monthly management accounts behind it. Not 'the pipeline is a risk' but the pipeline log and the last twelve signed letters of intent with the multiple paid on each. Where nothing can settle it — the exit multiple you assume, for instance — say so and price it in the grid instead of pretending it is a diligence item.

Is it acceptable to recommend proceeding while expecting to lose?

Yes, and on this case it is often the strongest answer available. If the price your hurdle supports sits well below what the vendor has described, the committee is better served by a paper that says so and asks for a bounded diligence budget than by one that manufactures a yes. The reviewer's next question is always why you chose that assumption, and 'because the deal otherwise did not work' is the answer no workbook can rescue.

I loved IB Vine. I’m going into Private Capital Advisory (PCA); you have the lessons on there for PCA and that was actually a game changer. I went into those interviews and knew about the core PCA concepts like net asset value, primary fundraising vs. secondary advisory, etc. I swear I was on IB Vine like a few hours a day. The opportunity to have that learning section and go through the questions people submit and everything — there’s no better tool out there. I loved the guides/lessons. The user interface is amazing. The way you’ve simplified it is so spectacular — it’s just so much easier to digest. It’s fun to use too; I’d rather use IB Vine than scroll through a guide. To be honest, I think the product is perfect. I genuinely owe you a big thanks.

IB Vine is a tool we really love to use in the club I’m a part of, and there’s really no other resource like it. You guys do a phenomenal job with the question bank. I recruited specifically for Energy banking, and IB Vine was my most used resource for generalist questions (which were about 50% of my interview questions; the rest being Energy-specific); the majority of such questions I saw in interviews were at least similar (if not the same) to the ones on IB Vine.

Once I read through the BIWS learning guides, I really didn’t refer to them again. I didn’t even really run through the 400 question guide once I found IB Vine, which I heard about through one of my classmates. We even get a free subscription (like most business schools) to Wall Street Prep, and if I’m being completely honest, I never even logged in to WSP. IB Vine is pretty much the only tool I used (along with our club question bank & mock interviews with peers) and it was invaluable for recruiting.
