Public Comps: 2026 Trading Comparables Methodology for M&A Bankers

Public Comps: How to Build a Public Company Trading Comps Set

public-comps

Public comps, short for public company comparable trading multiples, is the valuation method that benchmarks a target business against publicly traded peers using market-derived multiples such as EV/Revenue, EV/EBITDA, EV/EBIT, and P/E. It is the first valuation any sell-side analyst pulls up when a banker asks “where does this trade?” because it answers a different question than a discounted cash flow: not what the business is worth in theory, but what the market is pricing right now for businesses that look like it. The Goldman Sachs M&A practice, the Morgan Stanley equity research desks, and every bulge-bracket pitch book published between 2020 and 2026 lead with a public comps table on page 4 or 5 for exactly that reason (Goldman Sachs Insights).

This guide walks through how to build a defensible public comps set the way a first-year IB analyst at Houlihan Lokey or Lazard is taught to build one: peer screening, capital structure normalization, calendarization, multiple calculation, scrubbing for one-time items, and presenting a tight median/mean/quartile table that a managing director will not red-pen at 11pm the night before a fairness opinion goes out.

Public Comps in 60 Seconds: Quick-Reference Table

Element What It Is Typical Source Key Watch-Out
Peer set size 6-12 pure-play companies Capital IQ, FactSet, Bloomberg Too few = noisy median, too many = diluted comparability
Equity value (market cap) Shares outstanding x current price 10-Q cover page + closing price Use diluted shares via treasury stock method
Enterprise value (EV) Equity + debt + preferred + minority interest – cash Most recent 10-Q balance sheet Subtract only excess cash if operating cash is material
EV/Revenue EV / LTM or NTM revenue Filings + sell-side consensus Pre-profit SaaS uses this; mature industrials rarely
EV/EBITDA EV / LTM or NTM EBITDA Calculate EBITDA, do not trust GAAP Add back stock-based comp only when peers do
P/E Share price / diluted EPS Income statement Distorted by capital structure, tax rate, one-timers
Calendarization Align all peers to same fiscal year-end Manual stub-period math Required when one peer has Jan FYE and another Dec FYE
Output benchmark Median + mean + 25th/75th percentile Excel PERCENTILE.INC Median is the headline, mean shows skew

The full mechanics for each row are in the sections below. If you want to see how this same logic gets applied to a take-private LBO, the LBO model from scratch guide picks up where this one ends.

Why Public Comps Exist: The Market-Based Valuation Anchor

The three valuation methods every banker is trained on are intrinsic (DCF), market (public comps + precedents), and transaction (LBO). A DCF tells you what a business is worth based on a forecast of free cash flows and a discount rate; public comps tell you what the market is willing to pay today for businesses that share the same growth, margin, and risk profile (CFA Institute Curriculum, Equity Valuation).

The reason public comps anchor the football-field valuation chart that every banker shows their client is simple: a DCF is a hostage to its assumptions. Change the perpetuity growth rate from 2.5% to 3.0% and the implied equity value swings 15-25% in a typical industrial model. Public comps, by contrast, are observable. Apple closed at $234.41 on a given day, that is its price, no assumption required. The discipline of public comps is therefore not in the calculation but in the peer selection and the scrubbing.

A Morgan Stanley research note dated March 2025 on US software valuations noted that the median EV/NTM Revenue multiple for the 25-company SaaS coverage universe had compressed from 12.5x in late 2021 to 6.8x by Q1 2025, even as median revenue growth held steady at 18% (Morgan Stanley Insights). That kind of multiple compression is invisible in a DCF unless you are willing to mark your discount rate to market every quarter. Public comps make it impossible to ignore.

Step 1: Define the Peer Set

Peer selection is where most junior analyst comps sets fail their first review. The default temptation is to type the target’s industry code into Capital IQ and dump the top 25 results into the table. A managing director will throw that table back in five seconds. The correct screen is multidimensional.

The Five-Filter Peer Screen

  1. Industry classification (GICS or NAICS): Start with the target’s six-digit GICS sub-industry code. The S&P Global GICS taxonomy, jointly maintained by S&P and MSCI, is the institutional standard (S&P Dow Jones GICS).
  2. Business model: Recurring vs transactional, B2B vs B2C, asset-heavy vs asset-light. A pure-play SaaS peer is not a comp for a hybrid hardware-plus-services business even if both sit in the same GICS code.
  3. Size band: Target revenue +/- 50% is a reasonable starting band; widen to +/- 75% if the peer set comes back below 6. A $200M revenue target should not have $20B revenue Microsoft in its peer set even if the GICS code matches.
  4. Geographic mix: A US-only operator should not be benchmarked against a peer with 60% emerging-markets revenue, since FX and country risk premiums distort the multiple.
  5. Growth and margin profile: A 30% grower at 25% EBITDA margins is not a comp for a 5% grower at 25% EBITDA margins. Filter the long list down to peers within +/- 500 bps of revenue growth and +/- 500 bps of EBITDA margin.

A typical screen takes the 25-company industry universe down to 6-10 names. If you end up with 3, the target is genuinely unique and you should disclose that in the footnotes and supplement with precedent transactions. The sell-side analyst career guide covers how junior bankers are evaluated on the rigor of this screen during their performance reviews.

Step 2: Pull the Financials From the Right Source

Three data pulls drive every comps table: balance sheet (for the EV bridge), income statement (for the denominator), and shares outstanding (for the market cap). The source hierarchy is filings first, data provider second.

For UK and EU peers, the equivalent of EDGAR is Companies House and the ESMA filings portal. Annual reports filed under IFRS need a separate set of adjustments for capitalized R&D and IFRS 16 lease accounting before they are comparable to US GAAP filings (IFRS Standards List).

Step 3: Calculate Equity Value and Enterprise Value

Equity Value (Market Capitalization)

Equity value is diluted shares outstanding times current share price. Diluted is the key word: basic share count ignores options, RSUs, convertible notes, and warrants that are in the money. The treasury stock method (TSM) is the GAAP-mandated approach for options and RSUs; the if-converted method handles convertible bonds (ASC 260, Earnings Per Share).

Worked example: a company with 100M basic shares, 8M options struck at $20 with current price $50, has TSM-diluted shares of 100M + 8M – (8M x $20 / $50) = 100M + 8M – 3.2M = 104.8M. At $50 share price, equity value = $5,240M. This same logic feeds into the LBO sources-and-uses table covered in the LBO model step-by-step guide.

Enterprise Value (EV)

EV = Equity Value + Total Debt + Preferred Stock + Minority Interest – Cash and Equivalents. The Damodaran framework that every banker learns in training adds a few refinements: include capitalized operating leases (post-ASC 842 these sit on the balance sheet anyway), subtract only excess cash if the business needs working cash to operate, and include the unfunded portion of pension obligations as a debt-like item (Aswath Damodaran NYU Stern).

EV Bridge Line Item Source on 10-Q Treatment
Diluted equity value Cover page + closing price Add
Short-term debt Current liabilities Add at book value
Long-term debt Long-term liabilities Add at book value (use market value if bonds trade)
Operating lease liability Current + long-term lease liability Add (post-ASC 842)
Preferred stock Equity section Add at liquidation value
Non-controlling interest Equity section Add at book value
Cash and equivalents Current assets Subtract
Short-term investments Current assets Subtract if marketable
Unfunded pension Pension footnote Add (debt-like)

Step 4: Calculate the Numerator Multiples (EV/Revenue, EV/EBITDA, EV/EBIT, P/E)

Once EV and equity value are nailed, the multiples are arithmetic. The art is in choosing which multiple to feature.

EV/Revenue

EV / LTM Revenue and EV / NTM Revenue. Used when the business is unprofitable (early-stage SaaS, biotech, hyper-growth) or when EBITDA is too volatile to be meaningful. Bessemer’s State of the Cloud 2025 report tracked median EV/NTM Revenue for public cloud companies at 6.2x with a top-quartile of 11.4x (Bessemer Venture Partners State of the Cloud).

EV/EBITDA

The workhorse multiple for mature businesses. EV / LTM EBITDA is the headline; EV / NTM EBITDA gets the most attention from buy-side investors because it reflects forward earnings power. The Lincoln International Private Market Index publishes quarterly multiples that benchmark middle-market private deals against public peers; the Q1 2025 reading showed public EV/EBITDA at 10.8x median versus private at 7.5x (Lincoln Private Market Index).

EV/EBIT

Sometimes called EV/Operating Income. Used in capital-intensive industries (cement, steel, telecom infrastructure) where depreciation policy varies enough that EBITDA becomes misleading. A 10x EV/EBITDA business with $50M of D&A is a 16.7x EV/EBIT business if the D&A is real maintenance capex.

P/E (Price to Earnings)

Equity multiple, not an enterprise multiple. Share price / diluted EPS. The single most cited multiple in equity research, but the least useful for M&A because it folds capital structure into the denominator. A highly levered company will have a low P/E for the same EV/EBITDA, which makes apples-to-apples cross-peer comparison hard. Useful for sanity-checking the equity research target prices that consensus expects (S&P Dow Jones Indices).

PEG (P/E to Growth)

P/E divided by the projected EPS growth rate. A PEG of 1.0 is considered fair value in the Lynch framework; below 1.0 is cheap, above is expensive. Useful as a tiebreaker between two peers with similar P/E but different growth (SEC Investor.gov).

Step 5: Calendarize

Public companies have different fiscal year-ends. Apple closes its fiscal year in late September; Microsoft in late June; Costco in late August; most US industrials in late December. If you pull “LTM revenue” from Capital IQ for a peer set spanning these year-ends without calendarizing, you are comparing different time periods. In a rapidly growing or rapidly declining market, that mis-comparison is enough to move the median multiple by 10-20%.

The Calendarization Formula

To calendarize a peer with a non-December fiscal year-end to a December year-end, you stub-period the financials:

Calendar-year revenue = Most recent annual revenue + (Most recent stub period revenue) – (Prior-year same stub period revenue)

Worked example: Apple’s FY2024 ended September 28, 2024. To calendarize to December 31, 2024:

Apple actual figures from the 10-K filed November 2024 and 10-Q filed January 2025 (Apple SEC Filings). This same logic applies to EBITDA, EBIT, and EPS calendarization, applied line by line.

Step 6: Scrub for One-Time Items and Non-Recurring Adjustments

Reported GAAP EBITDA is almost never the “real” EBITDA a buyer would underwrite. The scrub list is long and industry-specific, but the common adjustments are:

The AICPA Audit and Accounting Guide on Revenue Recognition and the SEC’s Compliance and Disclosure Interpretations on non-GAAP measures both provide the regulatory boundary on what can and cannot be presented as “adjusted EBITDA” in a public filing (SEC Non-GAAP C&DIs).

Step 7: Build the Output Table

The final comps table that goes in a pitch book or fairness opinion has a standardized format. Banker convention is rows = companies, columns = multiples + operating metrics. The bottom rows show high, mean, median, low, and the target company itself (boxed and bolded).

Company Ticker Market Cap EV LTM Rev EV/Rev EV/EBITDA EV/EBIT P/E Rev Growth EBITDA Margin
Peer A PXA $4,250M $4,800M $1,200M 4.0x 14.5x 17.2x 22.5x 14% 27.6%
Peer B PXB $2,100M $2,400M $650M 3.7x 13.8x 16.1x 21.0x 11% 26.7%
Peer C PXC $8,900M $10,200M $2,800M 3.6x 12.1x 15.0x 19.4x 9% 30.1%
Peer D PXD $1,500M $1,650M $420M 3.9x 15.2x 18.0x 23.1x 16% 25.8%
Peer E PXE $6,200M $7,100M $1,950M 3.6x 13.0x 15.8x 20.2x 10% 27.9%
Peer F PXF $3,300M $3,750M $985M 3.8x 14.0x 16.5x 21.7x 12% 27.4%
High 4.0x 15.2x 18.0x 23.1x 16% 30.1%
75th pct 3.9x 14.4x 17.0x 22.3x 14% 27.9%
Mean 3.8x 13.8x 16.4x 21.3x 12% 27.6%
Median 3.8x 13.9x 16.3x 21.3x 11.5% 27.5%
25th pct 3.7x 13.2x 15.9x 20.4x 10% 26.9%
Low 3.6x 12.1x 15.0x 19.4x 9% 25.8%
Target TGT $2,750M $3,100M $780M 4.0x 14.2x 16.8x 22.0x 13% 28.0%

The Excel functions to populate the summary stats are PERCENTILE.INC(range, 0.25), MEDIAN(range), AVERAGE(range), MAX(range), MIN(range). Most bulge-bracket templates also include a Z-score column flagging any peer that is more than 2 standard deviations from the mean as a potential outlier to be excluded.

Steps 8 and 9: Choose LTM vs NTM and Apply to the Target

Step 8: LTM vs NTM

Two flavors of every multiple: trailing (LTM, last twelve months) and forward (NTM, next twelve months, or FY+1 and FY+2). LTM is fact-based, NTM is consensus-based. The choice depends on the deal context.

Context LTM or NTM Why
Sell-side pitch to client NTM Forward multiples typically lower, sets up the “your business deserves more” narrative
Buy-side fairness opinion LTM + NTM Show both, board needs the full picture
Cyclical business at trough NTM and FY+2 LTM understates earnings power at trough
Cyclical business at peak LTM only, or normalized NTM consensus often anchors to peak; LTM more conservative
Hyper-growth (SaaS) NTM Revenue + NTM ARR LTM is stale for a 50%+ grower
Distressed / restructuring LTM, then forward case Consensus often hasn’t reset; use management’s forward case separately

Step 9: Apply to the Target (Imply Equity Value)

Once you have median EV/LTM EBITDA and EV/NTM EBITDA from the peer set, multiply by the target’s LTM EBITDA and NTM EBITDA to imply a target EV range. Then bridge back to equity value by subtracting net debt.

Worked example: target LTM EBITDA = $55M, NTM EBITDA = $62M. Peer median EV/LTM EBITDA = 13.9x, EV/NTM EBITDA = 12.5x. Target net debt = $80M.

This implied equity range gets layered into the football-field chart alongside DCF, precedent transactions, and (if relevant) LBO floor analysis. The business valuation formula, methods, and math guide walks through how the four methods get reconciled on a single page.

Step 10: Trading Comps vs Transaction Comps

Public comps measure what the market pays for a public company on a normal trading day. Transaction comps (also called precedent transactions or M&A comps) measure what an acquirer paid in a control transaction, which by definition includes a control premium. The two should never be conflated.

Dimension Public Trading Comps Precedent Transaction Comps
Reflects control premium No (minority stake) Yes (typically 20-40% above trading)
Data freshness Real-time market Stale (months to years old)
Strategic synergies Not included Included in buyer’s price
Sample size 6-12 active peers 5-15 deals over 2-5 year window
Use case Where does it trade today What would a buyer pay

The Wachtell, Lipton, Rosen and Katz takeover compendium discusses how trading comps establish the floor for board negotiations and transaction comps establish the strategic-buyer ceiling (Wachtell, Lipton, Rosen and Katz). The control premium gap between the two is one of the most-debated topics in any fairness opinion, with empirical studies from the Deloitte Recap database showing a 28% median control premium across US public-target deals over the 2019-2024 window (Deloitte Recap M&A Database).

How Multiples Differ by Sector

There is no universal “right” EV/EBITDA. Sector economics drive the multiple. The McKinsey Valuation: Measuring and Managing the Value of Companies textbook, now in its 7th edition, devotes three chapters to how sector multiples should be interpreted (McKinsey Strategy and Corporate Finance).

Sector Headline Multiple Typical Range (2024-2026) Why That Multiple
SaaS / Cloud Software EV/NTM Revenue 4x-12x Pre-profit or rule-of-40 driven
Mature Software EV/EBITDA 14x-22x High margin, sticky revenue
Consumer Staples EV/EBITDA + P/E 11x-16x EBITDA, 18x-24x P/E Defensive, low growth, dividend-heavy
Industrials EV/EBITDA 8x-13x Cyclical, capital-intensive
REITs P/AFFO or P/FFO 15x-22x AFFO GAAP earnings distort due to depreciation
Banks P/Tangible Book Value + P/E 1.2x-2.0x TBV, 10x-14x P/E Balance sheet driven, regulatory capital
Insurance P/Book Value + P/E 1.0x-1.8x BV, 9x-14x P/E Float economics, reserve adequacy
Biotech (pre-commercial) Risk-adjusted DCF, not comps N/A No revenue, binary outcomes
Media and Entertainment EV/EBITDA 9x-14x Cord-cutting transition, mixed growth
Healthcare Services EV/EBITDA 10x-15x Reimbursement risk + roll-up dynamics
Energy (E&P) EV/EBITDAX 3x-6x Commodity-price exposed
Energy (Midstream) EV/EBITDA + Distribution Yield 9x-12x Fee-based, MLP structure

Sector-Specific Operating KPIs You Will Be Asked About

Beyond the standard EV/EBITDA, every sector has a banker-favorite operating KPI that the comp table needs to surface. Skipping these will get the table sent back.

Common Comps Mistakes That Get Junior Bankers in Trouble

Every analyst program at Goldman, Morgan Stanley, JP Morgan, Lazard, Houlihan Lokey, and Lincoln teaches the same comps mistakes to avoid. The list has not changed in 20 years (Lazard Insights).

  1. Pulling Capital IQ at face value: The standardized financials are a starting point, not a finished product. Always tie back to the 10-Q.
  2. Forgetting operating leases post-ASC 842: Pre-2019 comp tables ignore lease debt. Post-2019 they should not.
  3. Mixing GAAP and adjusted EBITDA across peers: If you add back SBC for peer A, do it for peer F.
  4. Not calendarizing: Especially fatal in a moving market.
  5. Including a peer that just announced a deal: The stock price has the bid premium baked in; the comp is no longer “trading” comp.
  6. Letting outliers drive the median: A 25x EBITDA peer in a 13x median set should be flagged and discussed, not silently included.
  7. Using stale forward estimates: Consensus refreshes after every earnings call. A pre-earnings NTM multiple may not match a post-earnings one.
  8. Not adjusting for IPO float dynamics: A company that IPO’d six months ago may have a low float and an inflated trading multiple. Use 30-day VWAP rather than closing price for IPO peers.
  9. Treating equity multiples as enterprise multiples: P/E and PEG are equity multiples and cannot be mixed in a table that otherwise uses EV-based metrics without flagging the inconsistency.
  10. Missing dual-class share structures: Companies like Alphabet, Meta, and Snap have multiple share classes with different voting rights but the same economic interest; sum all classes for diluted equity value.

When Public Comps Do Not Work (and What Replaces Them)

Public comps fail when (a) there are no good public peers, (b) the target is structurally different from any public peer, or (c) the market is dislocated (a 2008 or 2020 type event).

In each of these cases, the football-field chart will show a wider valuation range because the methodologies that work disagree more. That is honest valuation. Forcing public comps into a deal where they do not work is the most common cause of valuation overrun reported in Tax Court 280G excise tax cases involving golden parachute payments (see also the golden parachute 280G guide).

Who Uses Public Comps and How

How Public Comps Feed Into the Sell-Side and Buy-Side Process

Public comps are not a one-time pull. They get updated continuously through a transaction process and at multiple decision gates.

Process Stage Who Updates Comps Frequency Purpose
Pre-mandate pitch Sell-side analyst Once Establish valuation range to win the mandate
Kickoff after mandate Associate + analyst Weekly Refresh for IM and management presentation
Buyer outreach Associate Weekly Update bid range guidance for each round
First-round bids VP + associate Continuous Reconcile bids to comp-derived expected range
Final bids MD + VP Daily Negotiate final price against current trading
Fairness opinion FO committee Once at signing Defensible record for board minutes
Closing Junior banker Once Final comp snapshot for the bible

The work is most intense in the first-round and final-round bid stages because the trading multiples can move 5-10% in a quarter and a stale comp can result in advising a board to accept too low a price. The Delaware Chancery Court has been clear in cases like the 2024 Mindbody appraisal decision that boards relying on stale or methodologically weak comps face heightened fiduciary scrutiny (Delaware Court of Chancery).

How Public Comps Differ From DCF and Precedent Transactions

Method What It Tells You Strength Weakness
Public Comps What the market pays today for similar businesses Market-based, observable, current No control premium, peer set quality drives result
Precedent Transactions What acquirers have paid in control deals Includes control premium, real cash paid Stale, deal-specific synergies, often limited disclosure
Discounted Cash Flow Intrinsic value based on future cash flows Forward-looking, fundamental Assumption-sensitive, no market check
LBO Analysis What a financial sponsor could pay to hit IRR target Sets a floor in competitive auctions Only relevant when sponsor is a likely buyer

The four methods are complements, not substitutes. The discounted cash flow business valuation and DCF valuation business sale 2026 guides go deep on the DCF side; the paper LBO example walkthrough covers the LBO floor; and the how to determine the value of a business guide is the executive-level synthesis.

How a Buy-Side Analyst Uses Public Comps Differently

Sell-side bankers use comps to pitch a value; buy-side analysts at private equity firms and hedge funds use comps to test whether the market is mispricing a stock. The mechanics are identical but the conclusion is opposite. Where a banker says “the median is 13.9x, your business deserves 15x,” a hedge fund analyst says “my target trades at 11x, the median is 13.9x, there is 25% upside if the gap closes.”

The private equity analyst career guide covers how PE associates use trading comps as the entry-point screen for take-private opportunities. Apollo, KKR, Blackstone, Bain Capital, and TPG all run quantitative screens against the Russell 3000 looking for companies trading at 30%+ discounts to their sector median EV/EBITDA, then have associates dig into the bottom-quartile names to find the ones where the discount is unjustified (and therefore an LBO opportunity). The Pitchbook 2025 PE outlook noted that take-private deals as a share of US PE deal volume rose from 18% in 2023 to 26% in 2024, with valuation-arbitrage being the most-cited driver (PitchBook Reports).

How M&A Advisors Position Public Comps in a Pitch

An M&A advisor pitching a private business owner uses public comps to anchor the valuation conversation around objective data the owner can verify on Yahoo Finance. The structure of the pitch is consistent across boutique and bulge-bracket firms:

  1. Identify 6-10 publicly traded comparables.
  2. Show their current trading multiples (EV/Rev, EV/EBITDA, NTM Rev growth, NTM EBITDA margin).
  3. Apply a private-company discount of 15-30% (also called the marketability discount) to derive a private trading range.
  4. Add a strategic premium of 10-25% for the synergies a buyer would realize.
  5. Present the range as the expected outcome from a competitive auction process.

The marketability discount has been the subject of dozens of Tax Court opinions; the Mandelbaum v. Commissioner (T.C. Memo 1995-255) decision laid out the 10-factor framework still cited today by valuation firms in family limited partnership and gift-tax cases (US Tax Court).

TLDR: Public Comps Takeaways

Public comps are the market-based discipline that keeps every other valuation method honest. Master the peer screen, the EV bridge, the calendarization, and the scrub, and you can build a defensible trading multiples table for any business in any sector.
