How Sponsors Evaluate Deals: IRR, MOIC and the IC Process

Introduction

A sponsor's bid is the last link in a chain of promises. The fund has promised its limited partners (LPs) a return after fees and carried interest; the deal team has to show its investment committee (IC) a gross return wide enough to cover that gap; and lenders decide how much of the price debt can carry. KKR's annual report for 2025 shows how wide the first gap runs: across the private equity and real assets funds in its performance table, dating back to 1976, a 25.5% gross internal rate of return (IRR) became 18.6% net to investors. A sponsor therefore works from the return it must earn back to the price it can pay, and its return hurdle, its debt capacity, the cash the company throws off and the exit multiple it believes each move that ceiling. The approvals that test those inputs, from the first screen to the final IC, run on the seller's timetable, which lets a sell-side or coverage banker estimate each bidder's limit before the bids arrive.

The underwriting hurdle a sponsor applies to a deal is set by what its investors expect to receive, not by the deal itself. LPs judge a fund on net returns, what reaches them after management fees, fund expenses and the general partner's carry. Every one of those costs is paid out of the gross return the portfolio companies earn, so the deal-level target has to sit well above the number the fund will eventually report.

Gross Returns Must Cover Fees and Carry

KKR's fund table puts figures on the gap for individual vehicles. Asian Fund III, a 2017 vintage, shows a 24.1% gross IRR and an 18.8% net IRR; European Fund IV, from 2015, shows 21.0% gross and 16.0% net. About five points of annual return disappear between the companies and the LPs. A deal underwritten at 15% gross would leave investors near what public equities might offer, without the liquidity, so the gross-to-net spread is the first reason hurdles sit where they do. The fee and carry mechanics behind it are traced in how sponsors make money from fees and carry, and the net measures LPs compare across managers are set out in the Private Capital Advisory guide's article on reading a fund track record.

Where 25% and 2.5x Come From

The figures quoted for buyout hurdles have a documented source. In a survey of 79 private equity investors by Paul Gompers, Steven Kaplan and Vladimir Mukharlyamov, conducted between 2011 and 2013 and published in the Journal of Financial Economics in 2016, firms said they target a median IRR of 25% and a median multiple of invested capital (MOIC) of 2.5x, with a mean of 2.85x; over five years, 2.5x is roughly 20% a year. Fewer than 20% of respondents valued deals with discounted cash flow methods, and more than 85% said they adjust their target IRR for the riskiness of the company. The authors also noted that because fees come out of gross returns, sponsors must target well above a cost-of-capital rate to deliver a competitive net result.

The survey records stated practice from more than a decade ago, not a rule, and hurdles move with the asset and the strategy. Funds buying contracted or regulated cash flows accept lower targets, as infrastructure and real assets funds show; smaller firms in the survey targeted higher IRRs; and a sponsor may lower its bar for a defensive asset or raise it for a cyclical one.

Hurdle Rate (Private Equity)

The minimum return a private equity firm requires before it approves an investment, usually stated as a gross IRR and a gross multiple of invested capital over an assumed holding period. It differs from a fund's preferred return, which governs when the general partner begins to earn carried interest.

Two sponsors looking at the same company can therefore carry different ceilings before either opens the data room: one with a 20% target and cheap debt from a lender it has used for years, another with 25%, a smaller fund and less certain financing.

A sponsor does not value a company and then check whether the price works. It starts from the exit, subtracts the debt that will remain, divides by the multiple its hurdle requires and adds back the debt it can raise today. The full ability-to-pay method, including its place on a valuation football field, is set out in the valuation guide's article on what financial buyers can afford. Stripped of fees and interim cash flows, the logic fits on one line:

Each term has an owner. The required MOIC comes from the hurdle and the holding period, the debt from lenders, the net debt at exit from the company's cash generation, and the exit value from a multiple nobody can know in advance.

A Base Case in Round Numbers

Consider an illustrative company earning $100 million of EBITDA today, with lenders willing to provide 5.0x, or $500 million. The sponsor's plan takes EBITDA to $150 million in year five and assumes a sale at 10x, an exit value of $1.5 billion. Free cash flow after interest repays $250 million of debt over the hold, leaving $250 million of net debt and $1.25 billion of exit equity. With a hurdle of 2.5x over five years, about 20% a year, the most the sponsor can invest is $1.25 billion divided by 2.5, or $500 million. Add the $500 million of debt and the maximum price is $1.0 billion, 10.0x today's EBITDA.

How Each Input Moves the Ceiling

Changing one input at a time, with everything else held at the base case, shows which assumptions a sponsor's bid is most sensitive to:

Four readings follow from the grid:

The multiple arbitrage claimed by buy-and-build strategies is one exit argument an IC will test, and the operating plan behind EBITDA growth is the subject of the sponsor value creation playbook.

Debt Capacity: What Lenders Will Actually Lend

Lenders size a buyout loan with two main tests: total leverage, debt divided by EBITDA as the credit agreement defines it (often including adjustments the sponsor negotiates), and interest coverage, EBITDA divided by cash interest. For more than a decade, US bank regulators' 2013 interagency guidance on leveraged lending, which said leverage above 6x raised concerns for most industries, acted as a practical ceiling for many regulated banks. The Office of the Comptroller of the Currency (OCC) and the Federal Deposit Insurance Corporation (FDIC) rescinded that guidance in December 2025, telling banks to manage leveraged lending under general principles of safe and sound lending. For banks those two agencies supervise, and for direct lenders that were never subject to the guidance, the limit is now each lender's own credit appetite, the market-practice question explored in a guide to debt capacity analysis.

That sensitivity is why sponsors sound out lenders before the first round. Applied to the base case, the 12% scenario cuts debt to about $417 million while interest stays at $50 million a year, and the maximum price falls to about $950 million: roughly $50 million lost before any diligence finding, more than most management presentations can add.

ICs look at both measures because each conceals something the other reveals. The definitions and arithmetic are in the valuation guide's article on LBO returns; the coverage question is which one is the binding constraint for a given deal and which timing effects can make a result look better than it is.

IRR Rewards Speed, Including Borrowed Speed

IRR measures how fast money compounds, so anything that returns cash earlier raises it. A dividend recapitalization in year two can lift a deal's IRR while leaving its MOIC flat or lower, since the dividend is borrowed against the exit value, a trade-off examined in dividend recapitalizations from the coverage seat. Fund-level borrowing has the same effect: KKR's filing notes that financing facilities at fund level, by delaying when investors' capital is called, shorten the period over which IRRs are measured and tend to increase them when values grow. A quick flip shows the dollar problem: 1.5x in eighteen months is an IRR of about 31% on a profit too small to move a fund.

MOIC Ignores the Calendar, So the Binding Test Changes

MOIC counts dollars without dates: 2.0x over three years is an IRR of about 26%, while 2.0x over eight years is about 9%. Because most ICs require both a minimum IRR and a minimum multiple, which test binds depends on the expected hold. A 2.5x requirement on a three-year hold already implies about 36% a year, so the multiple is the binding test for short holds; on a seven-year hold, 2.5x is only about 14%, and clearing a 20% IRR would need about 3.6x, so the IRR test binds for long holds. A sponsor that expects a quick sale therefore argues about the multiple, and one that expects a long hold argues about the years. Longer holding periods have pushed many sponsors to emphasize the multiple and the cash actually returned, which is where the two measures meet the LP's view of the fund.

"Why do sponsors look at both IRR and MOIC?" is a common interview question, and the useful answer explains what each measure hides rather than defining both; the full verbal walkthrough of a sponsor's evaluation is in walk me through how a sponsor evaluates a deal.

Every sponsor bid is the output of staged approvals inside the firm, and the shape of those approvals varies from one sponsor to the next. KKR's annual report states the principle in one sentence: an investment team presents the investment and its risks to an investment committee or a portfolio manager, "which must approve each investment before it may be made."

Who Sits on the IC and How It Decides

ICs are usually made up of the firm's most senior investment partners, sometimes including founders, while the deal team that worked the opportunity presents and answers questions. Large multi-strategy managers tend to run separate committees by strategy or region; others centralize. Rhode Island's treasury staff, recommending a commitment to CVC Capital Partners IX in April 2023, described a centralized investment committee that lets the firm compare opportunities across 15 country teams. Voting rules (unanimity, majority, or a chair's veto) are rarely published and differ from firm to firm.

Approval thresholds come from two places. A firm's own policies decide which deals need its most senior committee, and fund agreements carry concentration limits on how much can go into one investment; KKR's filing lists such limitations among the policies each vehicle follows. A deal too large for one fund needs co-investors or a consortium, and some cross-fund or affiliated transactions need consent from the fund's LP advisory committee. Who does what inside a sponsor, from deal teams to operating partners, is mapped in inside a sponsor.

From Screening to Final Approval

Most sponsors approve a deal in stages, each committing more money and more of the firm's credibility with the seller. A screening discussion decides whether the asset fits the fund and deserves a diligence budget; a preliminary IC authorizes a first-round range and outside advisers; and a final IC approves the binding price, the equity commitment and the financing. Some firms add a further check before closing. How bidders position themselves between the rounds is the subject of sponsor bidders inside a sell-side auction; the stages line up with a banker-run auction as follows:

A final bid usually arrives with commitment papers from lenders, so the debt sizing in the IC memo is a negotiated term rather than an estimate; how those letters allocate closing risk is covered in sponsor deal terms and commitment letters. In a UK public-to-private, the Takeover Code goes further: a firm offer announcement must include a third party's cash confirmation, so financing is committed before the bid is public, as UK take-privates and the Takeover Code explains.

What an IC Memo Contains

Each approval stage rests on a written case that grows from a few pages at screening to a full document at final IC, and the committee's questions are aimed at the assumptions in the price grid above.

Investment Committee Memo (IC Memo)

The document a private equity deal team submits to its investment committee to request approval of an investment. A preliminary memo supports a first-round range; the final memo supports a binding bid and sets out the thesis, the returns cases, the financing and the risks the committee is asked to accept.

Formats differ, but final memos tend to cover the same ground:

Smartsheet: The Process Seen From the Seller's Side

A sponsor's IC never appears in a seller's filings, but its decisions do. The Smartsheet merger proxy traces how a consortium of Blackstone and Vista Equity Partners reached a $56.50 per share agreement in September 2024. The consortium's January 2024 indication at $56.25 was rejected. Its July 8 indication at $56.50 said it was highly confident of obtaining debt commitments before signing. The board's transaction committee then invited three more sponsors and one strategic buyer, and opened a data room with management's three-year forecast.

The other bidders fell away for the reason the ceiling arithmetic predicts. Two sponsors told the company's adviser, Qatalyst Partners, that they could not offer a premium to the share price, citing retention trends, slowing growth and recent changes to the business; a third later said the same. The consortium did not meet a July 26 deadline for a revised proposal, saying it needed more time to understand bookings trends and the next quarter's results, the kind of cash-generation question a final IC wants answered. On August 21 it repeated $56.50 as its "best and final offer," said it could sign four weeks after being allowed to approach lenders, and was cleared to contact them on August 24. The finalized debt commitment arrived the evening before signing, alongside equity commitments of up to $4.76 billion from Blackstone, Vista and an Abu Dhabi Investment Authority (ADIA) subsidiary. The transaction, valued at about $8.4 billion, completed in January 2025; the story of the Smartsheet acquisition covers the deal itself.

Almost every input in a sponsor's ability-to-pay calculation arrives through the sell-side bank, which makes the process design itself a way of influencing the price.

The Materials That Feed the Sponsor's Model

The CIM and the accompanying model frame the forecast every bidder starts from, which is why their construction matters, as this guide to preparing a CIM explains. Management meetings and the data room test whether the cash generation in that model is credible. Sell-side sensitivities, run on the bank's own version of the bidders' arithmetic, show the seller which assumptions carry the price. On financing, the bank can offer staple financing, which gives every bidder a leverage benchmark, or pass on lender feedback gathered from soundings; in Europe, vendor due diligence reports prepared for the seller let bidders' advisers confirm rather than rebuild the work.

Estimating What Each Sponsor Can Pay

With those inputs, a sell-side or coverage banker can rebuild each bidder's ceiling: the hurdle its strategy and fund position suggest, the leverage it can raise from the staple or its own lenders, the cash generation it will accept, and the exit multiple it is likely to believe. A sponsor late in its investment period with capital to deploy, read through the deployment and distribution clocks, may accept a lower hurdle; a sponsor that owns a related portfolio company may count cost savings from combining the two, which lets it bid more like a strategic buyer.

The output is a range for each bidder rather than a single number, and it is used at each decision point of the sale. It tells the seller whether the first-round bids are near the top of what each sponsor can pay or well short of it, which bidders deserve a place in the second round, and where price guidance can be set without driving the field away. It also shows which input separates the highest bidder from the next: if the gap is leverage, better lender feedback helps; if it is conviction about cash generation, more management time does.

Of the inputs behind a sponsor's ceiling, only the hurdle belongs to the sponsor alone. Leverage is set by lenders, cash generation by the diligence the seller controls, and the exit multiple by what the bidder can be brought to believe. A well-run sale process is largely an effort to move those three before each bidder's final IC meets, because once that committee has approved a number, a higher one usually needs a new approval.
