IPO Underwriter Selection Process: A 2026 CFO Walkthrough

If your company is targeting a public offering in the next 12 to 24 months, the single most consequential decision you will make is which investment bank leads your deal. Get it right and you have a credible bookrunner, a deep institutional order book, and a stable aftermarket. Get it wrong and you risk a broken deal, a first-day pop that leaves money on the table, or a stock that trades below the offer price within 30 days.

This guide walks through the IPO underwriter selection process step by step: when to start, how to run a bakeoff, what to ask, how to evaluate track records quantitatively, and how to negotiate the economics. It is written for CFOs and finance teams who need to make this decision, not just understand it.

Key takeaway: The bakeoff checklist every law firm publishes covers only half the job. The other half is understanding the economics (the 7% spread, the greenshoe, the lockup), the SEC registration mechanics the underwriter relationship drives, and how to read aftermarket data to separate a strong bookrunner from a convincing pitch.

When Should You Start the IPO Underwriter Selection Process?

Start building bank relationships 12 to 24 months before your target IPO date, not when you decide to file. RSM advises that the selection process should begin well in advance of the proposed offering to allow proper assessment of the underwriter relationship. Starting early also maximises the pool of banks willing to compete for your business.

The practical reason is simple: underwriters are selective. They vet companies before agreeing to take them public because their institutional clients hold them accountable for every deal they bring. A bank that brings a weak deal loses credibility with the buy-side. So the underwriter is simultaneously evaluating you as you evaluate them.

In the 12 to 24 months before a formal process, the goal is informal relationship-building:

• Accept meetings with investment bankers who reach out. These are intelligence-gathering sessions for both sides.
• Ask your auditors and SEC counsel for introductions. RSM notes that independent accountants and SEC counsel can make introductions to qualified underwriters with whom they have worked successfully.
• Meet the research analysts, not just the bankers. Orrick emphasises that developing relationships with research analysts at lead candidates is as important as the banker relationships, because those analysts will drive post-IPO coverage.
• Limit the number of banks you engage. Talking to too many firms risks the offering becoming widely known prematurely.

One structural advantage available to most growth companies: under the JOBS Act of 2012, emerging growth companies (EGCs) with less than approximately $1.07 billion in annual gross revenues can submit a draft S-1 confidentially to the SEC before any public filing. This means you can run a bakeoff, select your underwriter, and begin the SEC review process without any public disclosure, dramatically reducing market risk during the selection phase.

How to Run a Bakeoff: The Step-by-Step Process

A bakeoff is the structured competitive pitch process through which a company evaluates and selects its underwriting syndicate. Orrick describes it as a formal underwriter selection process that ideally follows months of informal relationship-building.

Here is how to run one effectively:

1. Define your criteria before the first pitch. Agree internally on how you will weight valuation, distribution capability, analyst quality, sector expertise, and team quality. If you do not set weights in advance, the highest valuation pitch will win by default, which is the most common mistake.
2. Invite three to five banks. Fewer than three limits competition; more than five creates noise and signals that your process is not serious.
3. Send a consistent briefing document. Give each bank the same financial information, your target timeline, and a list of specific questions you want answered. This makes pitches comparable.
4. Run presentations over two to three days. Each session should be two to three hours. Insist that the named individuals who will actually work the deal attend, not just the senior relationship banker.
5. Ask the hard questions (see the section below).
6. Check references. Call the CFOs of two or three companies whose IPOs the bank led in the past two years. Ask specifically about responsiveness during SEC comment letter rounds and aftermarket support.
7. Make the decision within two weeks. Delays signal indecision to the market.

Warning: RSM flags a critical caution that an underwriter who proposes to price the offering at an amount significantly higher than others may not be able to get the IPO completed at the quoted price or sustain the stock price in the market following the offering. The highest valuation pitch is a red flag, not a selling point.

What to Ask Underwriters in the Bakeoff

Most bakeoff questions focus on valuation methodology and peer group selection. Those matter, but they are table stakes. The questions that differentiate strong bookrunners from convincing pitches are the ones about execution and accountability.

Orrick's bakeoff framework structures the evaluation across four dimensions:

1. Understanding Your Business

• Does the bank have a dedicated institutional sales team and trading desk covering your sector?
• Does the research analyst's existing coverage of comparable companies demonstrate genuine sector insight?
• What are the bank's views on the biggest risk factors to a successful completion in the current market?

2. Ability to Position Your Story

• Which peer group would the bank use, and how would it position you relative to those peers to achieve the best valuation?
• What are the two or three key concerns investors will raise on the roadshow, and how would the bank guide your response?
• What is the bank's view on deal size, use of proceeds, and post-money valuation?

3. Track Record and Execution

• For each lead-managed IPO in your sector in the past three years, provide: initial filing range, final offer price, oversubscription multiple, overallotment option utilisation, and aftermarket price at 1, 2, 7, and 30 days.
• How many of those companies have done a follow-on offering, and how many months after IPO before the first follow-on?
• Have any of your publicly filed transactions been withdrawn or failed to price after the roadshow? What happened?
• What is your lockup waiver history? How often and under what circumstances have you waived the 180-day lockup?

4. Team Quality

• Who specifically will be on the deal team, day to day? Not the managing director who pitches, but the vice president and associate who will draft the S-1 sections and respond to SEC comments.
• What is the research analyst's institutional investor following, and what is their track record of initiating coverage promptly after the quiet period?

How to Evaluate Underwriter Track Records Quantitatively

Do not rely on the bank's self-reported data alone. Renaissance Capital recommends evaluating underwriter IPO performance over the first 90 days of trading as the primary track-record metric. That window is long enough to separate pricing discipline from first-day hype.

The data points to pull for each bookrunner, using platforms like Renaissance Capital IPO Pro, Dealogic, or Bloomberg:

Renaissance Capital puts it plainly: when the investment bank underwrites an IPO it is giving an implied endorsement of the company, signalling to investors "we like this deal." That endorsement is only worth something if the bank's prior endorsements have held up.

Understanding the Underwriting Economics

This is the section most bakeoff guides skip entirely. Understanding the economics is not just about cost, it is about incentives.

The Gross Spread

The standard underwriting gross spread for US mid-size IPOs is approximately 7% of gross proceeds, a convention that has persisted for decades and is documented in the underwriting agreement exhibits filed with every S-1 on SEC EDGAR. For IPOs over $1 billion in proceeds, spreads are typically negotiated down to 4 to 5%.

The 7% spread is divided into three components:

• Management fee (approximately 20%): paid to the bookrunners for managing the process.
• Underwriting discount (approximately 20%): retained by underwriters for bearing placement risk.
• Selling concession (approximately 60%): paid to syndicate members who actually sell shares to investors.

The selling concession allocation is where syndicate economics get political. Co-managers receive a share of the selling concession proportional to their role, which is why banks lobby for co-manager positions on deals they expect to perform well.

The Overallotment Option (Greenshoe)

The overallotment option, commonly called the greenshoe, allows underwriters to sell up to 15% more shares than the base offering size, the maximum permitted under SEC Regulation M. Granting it is standard practice and expected by institutional investors.

Here is how it works mechanically:

• The underwriter sells 115% of the base offering into the market at IPO.
• If the stock trades above the offer price, the underwriter exercises the option and purchases the additional 15% from the company (or selling shareholders) at the offer price, generating additional proceeds.
• If the stock trades below the offer price, the underwriter buys shares in the open market to support the price (stabilisation), using the short position created by the overallotment. This is the aftermarket stabilisation mechanism.

The greenshoe is not a cost to the company when the stock performs well. It is a price support mechanism when it does not. Companies should grant it.

The Lockup Period

The standard lockup period is 180 days, during which insiders and pre-IPO shareholders cannot sell shares. This is a contractual underwriter requirement, not an SEC mandate. Orrick flags that lockup waiver history is a key due diligence question: frequent waivers signal poor aftermarket discipline.

Lockup terms are negotiable. Common negotiating points include:

• Carve-outs for estate planning transfers or charitable donations.
• Tiered release schedules (e.g., 25% released at 90 days if the stock is above the offer price).
• Differentiated lockup periods for different shareholder classes.

Warning: The underwriter's firm commitment only becomes a commitment when the underwriting agreement is signed, as RSM emphasises. Everything before that, including the pitch valuation, is non-binding. Banks can and do walk away before signing if market conditions deteriorate.

How to Structure the Syndicate

The syndicate structure determines who gets paid, who does the work, and whose institutional relationships you access. Getting it right is a strategic decision, not an administrative one.

The left lead bookrunner carries the most responsibility and the most reputational exposure. Orrick notes that the lead underwriter coordinates the syndicate, assists in preparing the registration statement, conducts due diligence, provides the initial draft of the underwriting agreement and lockup agreements, and leads the selling efforts.

When to add a boutique co-manager: If your company operates in a specialised sector (life sciences, fintech, defence technology), a sector-specialist boutique as co-manager can add credibility with a specific institutional investor base that the bulge-bracket bookrunner may not reach as effectively. The boutique's research analyst may also carry more weight with that investor segment post-IPO.

Dual-class share structures: If your founders are retaining supervoting shares, tell every bank in the bakeoff. Some institutional investors (and certain index providers) have policies against dual-class shares, which limits the investor base a bookrunner can access. Ask each bank specifically about their experience placing dual-class IPOs and which institutional investors they can reach.

Firm Commitment vs. Best-Efforts: Which Structure Applies to You?

For a credible IPO, the answer is almost always firm commitment. Under a firm commitment, the underwriters agree to buy all shares at the offering price and bear the placement risk if they cannot resell them. Under a best-efforts arrangement, the underwriter acts as agent and the company bears the risk if shares cannot be sold.

RSM identifies the firm commitment as the optimal form because it provides more assurance that the company's stock will be sold. Institutional investors read the underwriting structure as a signal of the bookrunner's conviction in the deal.

What the Underwriter Does During the SEC Registration Process

The underwriter is not just a salesperson. It is a co-author of your legal disclosure and a defendant in waiting.

Under Section 11 of the Securities Act of 1933, underwriters can be held liable if the registration statement contains a material misstatement or omission, unless they can demonstrate they conducted a reasonable investigation (the "due diligence defense"). This legal exposure is why underwriters take their vetting process seriously and why their due diligence is thorough.

The underwriter's role in the SEC registration process maps to the following sequence:

1. S-1 drafting: The underwriter co-authors the registration statement, particularly the business description, risk factors, and MD&A sections. For the financial statement requirements that gate this process, see our IPO Financial Statement Requirements walkthrough.
2. Due diligence: The underwriter reviews material contracts, IP, litigation, and financial statements. It obtains comfort letters from the company's auditors (PCAOB-standard comfort letters confirming financial data in the prospectus).
3. Confidential submission (EGCs): Under the JOBS Act, EGCs can submit the draft S-1 confidentially. The underwriter manages this process and the SEC's initial review before any public filing.
4. SEC comment letter responses: The SEC staff will issue comment letters on the registration statement. The underwriter's legal team works alongside company counsel to draft responses. For a step-by-step playbook on this process, see our SEC Comment Letter Response guide.
5. Effectiveness and pricing night: The underwriting agreement is signed the night before pricing, after the SEC declares the registration statement effective. This is the moment the firm commitment becomes binding.
6. Roadshow: The underwriter manages the two-week institutional roadshow, scheduling one-on-ones with large institutional investors and building the order book.
7. Pricing: The underwriter prices the deal based on orders received, typically setting the final price after the market closes on pricing night.

The Research Analyst and the Quiet Period

For traditional issuers, underwriters cannot publish research for 25 days after IPO pricing (the quiet period). For EGCs under the JOBS Act, this restriction is significantly relaxed: underwriters may publish research before and immediately after the IPO. This makes the quality and institutional reach of the underwriter's research analyst even more important for EGC issuers, who represent the majority of technology and growth company IPO candidates.

ESG and Sustainability Diligence: What Underwriters Now Expect

Institutional investors, particularly large asset managers, now routinely ask about climate risk, governance structure, and DEI policies during the IPO roadshow. Underwriters with dedicated ESG advisory capabilities are better positioned to help companies frame these disclosures in the prospectus and respond to investor questions.

In the bakeoff, ask each bank:

• Does the bank have a dedicated ESG advisory team that works on IPO prospectus disclosure?
• Which institutional investors in the bank's distribution network have formal ESG screening criteria, and how would the bank position your company to those investors?
• What ESG disclosures have the bank's recent IPO clients included in their prospectuses, and what investor questions arose on the roadshow?

This is not a box-checking exercise. An underwriter that cannot help you anticipate ESG questions on the roadshow is leaving you exposed in front of the institutional investors whose orders you need to fill the book.

FAQ

What is the difference between a left lead bookrunner and a co-manager? The left lead bookrunner coordinates the entire syndicate, leads S-1 drafting, manages the SEC process, and prices the deal. Co-managers have smaller roles, typically contributing retail distribution capability or sector-specific research coverage, and receive a smaller share of the underwriting spread.

Is the 7% underwriting spread negotiable? For mid-size IPOs, the 7% convention is sticky. For deals over $1 billion in proceeds, spreads are typically negotiated to 4 to 5%. The structure of the spread (management fee, underwriting discount, selling concession) is also negotiable, particularly the allocation among syndicate members.

What happens if we need to withdraw the offering after filing? Withdrawing a publicly filed S-1 is costly in multiple dimensions: legal and accounting fees already incurred, reputational signal to the market, and damage to the underwriter relationship. Ask each bank in the bakeoff about their withdrawn deal history and the circumstances. A bank with multiple withdrawn deals may have a pattern of overpromising on market conditions.

How do we avoid picking an underwriter who will underprice our deal? Pull the bank's 30-day and 90-day aftermarket performance data for its last 10 lead-managed IPOs. Consistent first-day pops above 20 to 25% are a sign of systematic underpricing. Also ask the bank directly: what is its philosophy on pricing relative to the midpoint of the filing range, and how does it handle an oversubscribed book?

Does the JOBS Act affect which underwriters we can work with? Not directly, but EGC status changes the timeline and the research analyst rules. If you qualify as an EGC (under approximately $1.07 billion in annual gross revenues), your underwriter can publish research before and immediately after the IPO without the standard 25-day quiet period restriction. This makes the quality of the bank's research analyst more important, not less.

What post-IPO obligations does the underwriter carry? The underwriter's formal obligations end at closing, but the relationship should not. RSM emphasises that the underwriter must be capable of making a market for the company's shares and providing research and financial advice post-IPO. The frequency of follow-on offerings a bank leads for its IPO clients is the best proxy for whether it actually delivers on this commitment.

The 2026 IPO window has continued to open after the 2022 to 2023 drought, and companies that delayed their offerings are now competing for top bookrunner attention and calendar slots. Starting the selection process early, running a disciplined bakeoff, and understanding the economics before you sit across the table from a bank are the three things that separate companies that get the deal they deserve from those that get the deal they were sold.
