ECM Technical Questions: Valuation, IPO Process, and Product Mechanics

Introduction

ECM technical interviews probe four principal topic areas:

Strong technical preparation requires conversational fluency across all four areas plus the ability to handle follow-up probing on specific 2025-2026 deal applications. The technical question style in ECM is conversational rather than modeling-test heavy, with interviewers probing 5-10 minute discussions on each topic that test conceptual understanding rather than computational mastery. This article provides a comprehensive technical reference organized by topic area, with the answer fluency expected at first-round and Super Day technical interviews.

ECM bankers use the same valuation methods as broader IBD with specific emphasis on IPO-pricing applications.

Public Comparable Companies

Public comparable companies analysis values the issuer using trading multiples of similar publicly-traded companies. Principal multiples include P/E (price-to-earnings, used for profitable companies), EV/EBITDA (enterprise value to EBITDA, the most common multi-sector multiple), EV/Sales (used for unprofitable growth companies), P/B (price-to-book, used for financial-services companies), and sector-specific multiples (EV/ARR for SaaS, P/AUM for asset managers). The analysis identifies a peer group of 5-10 closest comparable companies, calculates their multiples, applies the median or selected average to the issuer's financials, and produces an implied valuation range. Public comps is the primary IPO valuation method because the issuer will trade at public-market multiples post-IPO.

Discounted Cash Flow

DCF analysis values the issuer based on projected future cash flows discounted at the weighted average cost of capital. The analysis projects 5-10 years of free cash flows, applies a terminal value (Gordon growth or exit multiple), discounts at WACC, and produces an intrinsic enterprise value. ECM bankers use DCF as a secondary check on the public comps valuation; DCF is typically less influential in IPO pricing because public-market valuations are anchored to comparable trading multiples rather than intrinsic value calculations.

Precedent Transactions

Precedent transactions analysis values the issuer using transaction multiples from comparable M&A deals or prior IPOs. The analysis identifies 5-10 comparable transactions, calculates the transaction multiples, applies them to the issuer's financials, and produces an implied valuation. Precedent M&A multiples typically include a 20-40 percent control premium plus synergy pricing, so they run materially above trading comps; the typical ranking from low to high is trading comps < DCF < precedent M&A transactions, though hot markets can invert this with comps exceeding transactions. ECM bankers use precedent IPOs (recent IPOs in the same sector) as the more directly relevant precedent set, with precedent M&A as a directional ceiling check rather than the primary valuation anchor.

The IPO Discount

IPO Discount

The discount applied to comparable public-market multiples to set the IPO price range, typically 10-20 percent of the comparable trading multiple. The discount serves three structural purposes: compensating IPO investors for primary-market risk, supporting first-day positive trading momentum, and absorbing the valuation uncertainty inherent in the private-to-public transition. The discount level varies with market conditions (wider in difficult markets), issuer quality (narrower for premier issuers), and demand expectations (narrower for oversubscribed deals).

The IPO discount is the discount applied to the comparable public-market multiple to set the IPO price range. The standard discount runs 10-20 percent depending on market conditions, issuer quality, and demand expectations. Stronger-quality issuers with high cornerstone demand may price at the lower end (10 percent discount); weaker-quality or high-uncertainty issuers may require larger discounts (20 percent or more). The discount serves three structural functions: compensating IPO investors for taking primary-market risk, supporting first-day positive trading momentum, and absorbing the inherent valuation uncertainty of a transitioning private-to-public company.

The IPO process has specific mechanical elements that ECM technical interviews routinely probe.

S-1 Registration Statement

The S-1 is the principal SEC filing for IPO registration, containing the prospectus that describes the issuer's business, financial statements, risk factors, use of proceeds, MD&A, executive compensation, and other required disclosures. S-1 drafting typically takes 2-3 months from kickoff and involves the issuer's senior management, multiple legal teams, the bookrunner banks, and the auditor. The S-1 is filed with the SEC and made publicly available; emerging growth companies under the JOBS Act can file confidentially first and only make the S-1 public when ready to launch the formal marketing process.

SEC Review and Comments

The SEC's Division of Corporation Finance reviews the S-1 over typically 8-12 weeks, issuing comment letters that the issuer responds to with revised filings. The review process iterates through 2-4 comment letter rounds before the SEC declares the registration statement effective. The 2025 federal shutdown's effect on the IPO calendar (43 days of suspended SEC review) illustrated how SEC review is a structural gating function for the broader market.

The Roadshow

The roadshow is the 1-2 week marketing process during which issuer management plus the bookrunner team meet institutional investors to build demand. Roadshows typically include 50-100 investor meetings across major financial centers (NY, Boston, San Francisco, London, Hong Kong for international deals). The roadshow output is investor demand data that supports the bookbuilding process and final pricing call.

Bookbuilding

Bookbuilding is the process by which the bookrunner banks collect and analyze investor demand at different price points. The book typically includes long-only mutual funds, hedge funds, sovereign wealth funds, pension funds, and increasingly retail investors through mobile broker access. The bookrunner team analyzes demand quality (price sensitivity, holding period intent, fundamental view), oversubscription levels, and demand distribution to inform the pricing decision.

The Pricing Call

The pricing call is the night-before-IPO conference call where the issuer's senior management, the bookrunner team, and selected investors finalize the IPO price. The decision considers final demand data, overnight market conditions, comparable trading dynamics, and the issuer's specific objectives. Pricing decisions can fall within the indicated range, above the range (when demand justifies an upsize), or below the range (when market conditions weaken or the issuer specifically prioritizes clean post-IPO trading).

Greenshoe and Stabilization

Greenshoe Option

The overallotment option built into IPO underwriting agreements that allows the bookrunner banks to sell up to 115 percent of the offered shares (15 percent additional) and use the additional shares to support post-IPO price stabilization through open-market purchases if needed. The greenshoe is exercised in full when the stock trades above the offering price (the underwriters complete the additional 15 percent issuance at the IPO price); the greenshoe is partially or fully unexercised when the stock trades below the offering price, with the stabilization agent using the additional 15 percent to buy shares in the open market.

The greenshoe option (formally an overallotment option) allows the underwriters to sell up to 115 percent of shares (15 percent additional) to support post-IPO price stabilization. The mechanism creates a covered short position for the syndicate: underwriters sell the additional 15 percent at IPO price, then use the proceeds to either buy shares in the open market (if the stock trades below offering price, supporting the price floor) or exercise the greenshoe at IPO price (if the stock trades above offering, completing the additional issuance). Rule 104 of Regulation M (which replaced former Rule 10b-7 in 1996) provides the conditional safe harbor for stabilizing transactions: underwriters may bid at or below the offering price and create the covered short position up to 15 percent without immediate covering obligations, provided activities support stabilization rather than manipulation.

Lockup Periods

Lockup periods restrict insider selling for typically 180 days post-IPO, with selected modifications (early-release provisions for top-quartile aftermarket performers, staggered releases). The lockup expiration is a known supply event that affects post-IPO trading; ECM bankers track the lockup calendar as a structural input into broader market analysis.

Beyond IPOs, ECM bankers execute multiple follow-on equity products, each with distinct pricing economics and execution speed.

Marketed Follow-On Offerings

Marketed follow-ons are publicly-marketed equity issuances by already-listed issuers, typically completed in 2-3 weeks with a compressed roadshow. Pricing typically includes a 5-10 percent discount to the prevailing market price; the bookrunner mix often differs from the original IPO syndicate based on subsequent franchise positioning.

Overnight Bought Deals

Overnight bought deals are accelerated equity issuances completed after market close in a single overnight window. The bookrunner banks commit to buying the shares at a fixed price (the bought-deal price) and then immediately resell to institutional investors. The structure provides execution speed and pricing certainty at the cost of a deeper discount (typically 5-15 percent below market).

Block Trades

Block trades are large secondary share sales by existing shareholders (selling stockholders) executed through a single broker. The structure varies from accelerated bookbuilds (overnight execution similar to bought deals) to standalone block trades (executed during market hours through a broker desk). Block trades are common for sponsor sell-downs post-lockup, founder secondary monetization, and cornerstone investor exits.

ATM Programs

At-the-Market (ATM) programs allow already-listed issuers to issue equity in small dribble-out tranches over time at prevailing market prices. The structure provides flexibility (issuer controls timing and size) without the pricing discount of marketed follow-ons. ATM programs typically run for 2-3 years and authorize issuance up to a specified dollar amount or share count.

Accelerated Share Repurchases (ASRs)

ASRs are share buybacks executed in a single transaction (rather than open-market repurchases over time) where the issuer pre-pays for a specified dollar amount of shares and the bank delivers them based on a forward-pricing formula. The structure provides immediate share-count reduction (supporting EPS) at predictable pricing.

Rights Offerings

Rights offerings give existing shareholders the right (but not obligation) to purchase additional shares at a fixed price, typically below market. The structure protects existing shareholders from dilution if they participate; non-participating shareholders see their stake diluted. Rights offerings are common in Europe and for distressed-issuer recapitalizations in the US.

The following question bank reflects the most-frequently-asked technical questions in ECM Super Day rounds, organized by topic area. Candidates should drill 60-90 second answers on each.

Process Questions

"Walk me through the IPO process from kickoff to first day of trading." (Expect a 90-second answer covering kickoff and bake-off, S-1 drafting, SEC review, roadshow, bookbuilding, pricing call, allocation, first day trading.) "What's the difference between a confidential and public S-1 filing?" (Confidential filing is available to JOBS Act EGCs allowing pre-public review; the issuer can stay confidential through SEC review and only make the S-1 public when ready to launch the formal marketing.) "What is testing the waters and when can it happen?" (TTW meetings allow EGCs to communicate with QIBs and institutional accredited investors before the S-1 is publicly filed, supporting early demand calibration.)

Pricing Questions

"How would you price an IPO?" (Build comparable public companies analysis, calibrate the IPO discount of 10-20 percent against market conditions, validate against DCF as secondary check, set initial range for marketing, refine through bookbuilding demand data.) "What is the IPO discount and why does it exist?" (10-20 percent below comparable multiples; compensates IPO investors for primary risk, supports first-day momentum, absorbs valuation uncertainty.) "Why are most IPOs underpriced?" (Information asymmetry between issuer and investors, primary-market risk premium, the IPO discount mechanism, demand-curve calibration during bookbuilding, structural preference for clean post-IPO trading over absolute proceeds maximization.)

Product Questions

"What is the difference between a marketed follow-on and an overnight bought deal?" (Marketed FOs use 2-3 week public marketing with 5-10 percent discount; bought deals execute overnight at fixed bank-committed price with 5-15 percent discount but speed and certainty.) "When would an issuer use an ATM versus a marketed FO?" (ATM provides flexibility and small-tranche execution at market prices; marketed FO provides large-size execution with deeper discount.) "How does a capped call affect convertible bond economics?" (Synthetically raises the effective conversion price by buying calls at conversion strike and selling calls at the cap; produces dilution protection up to the cap level.)

Equity-linked products combine equity and debt characteristics through embedded options.

Convertible Bonds

Convertible bonds are debt instruments that include an embedded option to convert to a specified number of issuer common shares at a fixed conversion price. Principal terms include the coupon (typically 0-5 percent in current markets, with high-vol issuers like CoreWeave and Strategy at 0-2 percent), the conversion premium (typically 25-45 percent above the issuance-date stock price), the maturity (typically 5-7 years), and any embedded call or put features.

Convertible Bond Valuation

Convertible bonds are valued using the bond-plus-option approach: the bond component is valued using straight-debt yields for the issuer's credit rating; the embedded option is valued using Black-Scholes or binomial tree methods with inputs including the stock price, conversion price, time to expiration, stock price volatility, and dividend yield. The total convertible value equals the bond value plus the option value.

Capped Calls

Capped Call

An equity derivative executed concurrent with convertible bond issuance to synthetically raise the effective conversion price for dilution purposes. The capped call buys call options at the conversion price and sells call options at a higher cap price, producing dilution protection up to the cap. CoreWeave's December 2025 convertible used capped calls at 150 percent above issuance, raising the effective conversion price from $107.80 to $215.60. The structure is common in modern AI capex convertibles where issuers want to preserve the economic benefit of equity upside without the underlying convertible's full dilution exposure.

Capped calls are equity derivatives executed concurrent with convertible issuance to effectively raise the conversion price for dilution purposes. The capped call buys call options on the issuer's stock at the conversion price and sells call options at a higher cap price (typically 50-100 percent above the conversion price). The structure produces synthetic dilution protection up to the cap price; CoreWeave's December 2025 convertible included capped calls at 150 percent above issuance, raising the effective conversion price to $215.60 per share versus the $107.80 stated conversion price.

Exchangeable Bonds

Exchangeable bonds are similar to convertibles but exchangeable into shares of a different company (typically a subsidiary or strategic holding) rather than the issuer's own shares. Alibaba's HK$12 billion 2025 exchangeable into Alibaba Health shares illustrates the cross-holding monetization use case for the structure.

Mandatory Convertibles and Preferreds

Mandatory convertibles automatically convert to common stock at maturity (typically 3-5 years), providing the issuer with equity-credit treatment from rating agencies. Perpetual preferreds (Strategy's STRC, STRK, STRF, STRD suite illustrates the modern variants) provide structural equity-credit benefits with fixed-dividend or variable-dividend mechanics.
