The first call you should make on day one of private equity ownership is to your sponsor, and it is one question long: what number did you underwrite? That is the whole answer to this post’s title, delivered up front. Everything else here is why that call matters, why almost nobody makes it, and what to do with your first hundred days once you have the answer. I am writing this to the CEO sitting in the seat the morning after close — whether you were retained through the deal, promoted into it, or recruited for it. I have been that CEO more than once, I now chair businesses on the other side of that phone call, and I have watched the first week under sponsor ownership set the trajectory of entire hold periods. Roughly seventy percent of PE-backed CEOs get replaced, most of them in months eighteen through twenty-four. The seeds of that statistic are planted in week one.
The Question Almost Nobody Asks
Your sponsor built a model to buy your company. In that model is a number — the EBITDA at exit that makes the fund’s math work, and behind it the entry assumptions about price, mix, growth, and cost that justify the multiple they paid. That number is the actual definition of your job. Not the budget, not the board deck language about “building a great business.” The underwriting case. And yet most CEOs never ask to see it. Some assume it is confidential. Some are afraid the answer will be unreasonable. Most simply do not think of the deal model as something that concerns them — it was the deal team’s document, and they are the operations person. That framing is the first mistake of the hold period. You cannot hit a number you have never seen, and you cannot push back on a number you have never seen either.
Here is what happens when you ask. In my experience, on both ends of the call, the sponsor’s respect for you goes up immediately. Sponsors spend their lives worrying that management does not understand the deal. A CEO who calls on day one and says, in effect, show me the model, tell me what you underwrote, walk me through the bridge you believe in — that CEO has just identified themselves as someone who understands that the enterprise value is the product. There is no downside. If the underwritten number is sane, you now have your true north. If it is aggressive, far better to discover that in week one, when you can still shape the plan, than in month eighteen, when it is being used as the case against you.
Listen carefully to how the answer arrives, because the call is also a diagnostic on your sponsor. A good sponsor walks you through the model without hesitation and tells you which two or three levers the deal actually depends on — every deal has them, and they are rarely the ones the investment memo leads with. A sponsor who hedges, delays, or sends you a summary instead of the model is telling you something about how this partnership will run, and you want that information in week one too. Either way, take notes and repeat the number back before you hang up. I have seen holds go sideways over a misunderstanding as basic as whether the underwritten figure was EBITDA or adjusted EBITDA, and which adjustments survived the quality of earnings work. Precision in this first conversation is not pedantry. It is the foundation everything else in this post stands on.
What to Do in Week One: Almost Nothing
After the call, the correct posture for your first week is strategic quiet. Request the data — the full deal model, the diligence reports, the quality of earnings work, customer and product profitability at whatever grain exists. Meet the team, one on one, and mostly listen. Say very little. Announce nothing. The pressure to perform arrival — the town hall with the new vision, the quick symbolic decision, the reorganization that shows energy — is enormous and almost entirely counterproductive. Every early announcement is a check your data has not yet cleared. I have watched new CEOs commit to “no facility closures” in week two and spend year two eating those words, and I have watched others declare a growth push before discovering that a third of the revenue was unprofitable. The market for day-one drama is your own anxiety. Decline to sell to it.
The Honeymoon Is a Trap
The most dangerous document of your first quarter is the budget somebody will ask you to bless before you have seen the concentration cut. Here is the trap in slow motion. The deal closes in, say, March. The company has an operating budget built by the prior regime, or the sponsor has a year-one plan derived from the deal model. Everyone is friendly — it is the honeymoon — and agreeing to the numbers feels like team play. But you have not yet run the 80/20 cut. You do not yet know that two customers produce most of the profit, that an entire product family loses money at full cost, that the backlog quality is worse than the diligence suggested. Agree to the budget now and you have signed your name to arithmetic you have never audited. Every miss for the next four quarters is yours, attached to a plan you inherited. The honeymoon is precisely the period when you have maximum permission to say “I do not know yet” — and it expires the moment you sign the number.
Negotiate the First Hundred Days as Discovery
So negotiate the frame explicitly. In that same first call, or the first board session, propose the deal: give me a hundred days of discovery, not performance. In that window I will run the full diagnostic — customer and product profitability at the transaction level, pricing tests, team assessment, operational walk-throughs of every major site. At the end of it I will bring you a value creation plan built on data we both trust, tied to the number you underwrote. In exchange, I am not defending a budget I did not build during those hundred days; we run the business on the prior plan and flag variances honestly. Every sponsor I have ever known accepts this deal when it is proposed with confidence, because it is obviously in their interest: they get a real plan instead of inherited fiction. The CEOs who get hurt are the ones who never propose the frame and drift into being measured from day one against numbers nobody validated.
Two objections come up when I coach CEOs on this frame, and both have clean answers. The first: my sponsor expects quick wins, and a hundred days of study looks passive. Fine — discovery is not passivity, and you should harvest the obvious money as you find it. Every business I have ever walked into had two or three pricing corrections and a couple of spending absurdities that required no study at all. Take them, report them, and be explicit that they are down payments, not the plan. The second objection: what if discovery reveals the deal thesis is wrong? Then you have just done the most valuable hundred days of work in the fund’s portfolio. A thesis that is wrong is wrong whether or not anyone says so; the only variable is whether it gets said while there is still time to build a different bridge. Sponsors do not shoot the messenger in month three. They shoot the messenger in month twenty, for having known and said nothing.
Build the Bridge With Them, Not for Them
When the discovery window ends, the deliverable is a five-lever EBITDA bridge — price, mix, share gain, M&A, cost — from current earnings to the underwritten exit number, with an owner and a date on every line. The critical word in this section is with. Do not disappear for a hundred days and return to present a finished plan for approval, and absolutely do not sit and wait to receive one. A plan presented to a sponsor gets audited; a plan built with a sponsor gets defended. Bring the deal team into the working sessions where the levers get sized. Let them argue you down from an aggressive price assumption; let them see the data that kills a growth fantasy from their own model. By the time the plan reaches the board, it should have no surprises in it for anyone, because its co-authors are sitting around the table. This is also, quietly, how you renegotiate an aggressive underwriting case — not by contesting it, but by rebuilding it together on better data.
The Reporting Offer That Buys Trust
Then make an offer no sponsor will refuse: I will show you the plan monthly, by lever, owners named. One page. Each lever’s target for the year, progress against it, variance, and the countermeasure for anything red — with the name of the executive who owns the line printed next to it. This costs you one page a month and buys you the single most valuable asset a PE-backed CEO can hold: a sponsor who is never surprised. Sponsors do not replace CEOs for missing numbers; they replace CEOs for missing numbers they did not see coming, explained by narratives that keep changing. The monthly lever report makes your performance legible. When a line goes red — and lines go red in every hold — the conversation starts from shared data and an existing countermeasure, not from suspicion. I have run this exact reporting rhythm in every sponsor-backed seat I have held, and it has bought me patience in bad quarters that other CEOs did not get.
- One page, monthly. The five levers, year-to-date progress, variance, countermeasures. If it needs a second page, it is hiding something.
- Owners named. Every lever line carries an executive’s name. Accountability that is visible to the board is accountability that actually operates.
- Red flagged by you first. The entire value of the system is that the sponsor never learns bad news from anyone but you, and never later than you knew it.
My First Call Done Right
Two stories, because I have run this play both ways. The one done right: taking over a sponsor-backed industrial company doing a bit under a billion, I made the underwriting call before I had a badge photo. The managing partner walked me through the model that afternoon — the exit EBITDA, the multiple assumptions, the three levers the deal actually depended on. Two of the three matched what I saw in the business. The third, a share-gain assumption in a segment I knew well, was fiction, and I said so in week one. We rebuilt that lever together during a ninety-day discovery window and replaced the missing EBITDA with a pricing program the model had barely touched. That plan held for the whole hold. The board meetings were boring in the best way. When we exited, the partner told me the week-one call was the moment he stopped worrying about the management risk in the deal. One phone call, made early, priced like that.
My First Call Done Wrong — and Repaired
The one done wrong: years earlier, younger, I took a seat and did what most CEOs do — put my head down and started operating. I assumed the budget I inherited reflected the deal, assumed the sponsor would tell me what mattered, and spent six months running hard at targets I had never audited. Then a soft quarter landed, and in the board meeting I discovered the real underwriting case for the first time — as the standard I was being measured against and missing. The trust deficit was entirely of my own making; nobody had hidden the model, I had simply never asked. The repair took most of a year: I requested the deal model retroactively, rebuilt the bridge from actual transaction data, brought the sponsor into every working session, and started the monthly lever report I should have started in week one. It worked — that hold ended well — but I bought back at a premium what I could have had for free in the first week. The tuition on that lesson is why this post exists.
The Mindset: Operator With Capital and a Clock
Underneath all the mechanics is a mindset shift that most first-time PE-backed CEOs never quite make. You are not an employee with a boss. You are an operator with capital and a clock. The sponsor is not management; they are the capital, with a defined return requirement and a defined time horizon, and you are the person deploying that capital through a business. Employees wait to be told the number. Operators ask for the model on day one, negotiate the discovery window, co-author the bridge, and report by lever because that is simply how a capital deployment gets governed. The seventy percent replacement statistic is, at bottom, a mindset statistic: most of the replaced CEOs were competent operators who related to their sponsor like a boss to be managed instead of capital to be deployed. The clock is real — five years, give or take — and it should discipline you, not frighten you. A clock is just a cadence with an ending.
The mindset also settles a question that quietly torments a lot of first-time PE-backed CEOs: how much deference do I owe these people? The answer is none, and all — none to their opinions about operations, all to their arithmetic. The sponsor knows things you should absorb completely: the return the fund needs, the exit environment they are steering toward, what buyers in your space are paying for and punishing. You know things they never will: what the machines can do, which customers are one price increase from leaving, which plant manager is holding a building together with willpower. The healthy relationship trades these honestly in both directions. The unhealthy versions are both failures of the same mindset — the CEO who treats the sponsor as a boss to be pleased stops surfacing bad news, and the CEO who treats the sponsor as an adversary to be managed stops surfacing anything at all. Capital and operator, each doing their actual job. It is not complicated. It is just rare.
Your First Week, in Order
So here is the whole playbook, compressed. Day one: call the sponsor, ask what they underwrote, request the model and the diligence file. Week one: meet the team one on one, request the transaction-level data, announce nothing. First board conversation: negotiate the hundred-day discovery window explicitly. Days one through one hundred: run the diagnostic, build the five-lever bridge with the sponsor in the room. Day one hundred: deliver the plan, propose the monthly lever report, and start the cadence that will run for the rest of the hold. None of this requires permission you do not already have, and all of it is easiest to do in the first weeks, when your questions are expected and your ignorance is free.
If you want to work through the playbook live — the call, the discovery window, the bridge, the report — I run a free biweekly workshop for PE-backed CEOs through The 80/20 Institute where we do exactly that, with sitting CEOs, on real situations. Bring the deal you are living. The first hundred days only happen once, and they are cheaper to get right than to repair. I have paid both prices, and I can tell you the difference to the decimal.
Frequently Asked Questions
What Should a Newly PE-Backed CEO Do on Day One?
Call the sponsor and ask one question: what number did you underwrite? Request the full deal model, diligence reports, and quality of earnings work. The underwriting case — not the budget — is the actual definition of the job, and sponsors consistently respect CEOs who ask for it immediately. Beyond that call, the correct day-one posture is quiet: meet the team, gather data, announce nothing.
Why Do Most PE-Backed CEOs Never See the Deal Model?
Most assume it is the deal team’s confidential document, fear the number will be unreasonable, or see themselves as the operations person rather than a party to the investment. That framing is the first mistake of the hold period. You cannot hit — or intelligently push back on — a number you have never seen, and discovering an aggressive underwriting case in month eighteen is far worse than discovering it in week one.
What Is the Honeymoon Trap After a PE Deal Closes?
Agreeing to a budget before seeing the concentration cut. In the friendly early weeks, blessing inherited numbers feels like team play, but until you have run 80/20 profitability analysis at the customer and product level, you are signing arithmetic you never audited — and every subsequent miss is yours. The honeymoon is exactly when you have maximum permission to say you do not know yet.
How Should a New CEO Structure the First 100 Days Under PE Ownership?
Negotiate it explicitly as a discovery window, not a performance window: a hundred days to run the full diagnostic — transaction-level profitability, pricing tests, team assessment, site walk-throughs — ending with a five-lever value creation plan built with the sponsor and tied to the underwritten number. Sponsors accept this frame when it is proposed confidently, because a real plan serves them better than inherited fiction.
How Does a PE-Backed CEO Build Trust With the Sponsor?
A monthly one-page report, by lever, with owners named: each value creation lever’s target, progress, variance, and countermeasure, with the responsible executive’s name on every line. Sponsors rarely replace CEOs for missing numbers; they replace CEOs for surprises. A reporting rhythm that guarantees the sponsor never learns bad news late — or from anyone else — buys patience in bad quarters that other CEOs do not get.
