The underwriting syndicate is not just a transaction mechanic — it is the company's interface with the institutional investor market. The lead bookrunner's sales force, analyst franchise, and investor relationships determine which funds hear the equity story first, how the story is framed, and which investors end up as long-term core shareholders. Getting this selection right matters far beyond the IPO itself.
What Underwriters Actually Do
Investment bank underwriters serve several functions simultaneously in an IPO — and understanding all of them helps management evaluate which banks are best positioned to serve the company's specific needs.
They guarantee the offering. In a firm commitment underwriting — the standard structure for U.S. IPOs — the underwriting syndicate commits to purchase the offered shares from the company at the offering price. The underwriters bear the risk that they cannot resell those shares at or above the offering price. This guarantee is why the underwriting spread exists.
They manage the bookbuild. The lead bookrunner's sales force contacts institutional investor clients, presents the investment thesis, collects orders at various price points, and builds the order book that determines final pricing. The quality of the underwriter's institutional investor relationships is the primary determinant of bookbuild quality.
They allocate shares. The lead bookrunner controls how shares are allocated among investors — deciding which funds get large allocations and which get nothing. This power gives underwriters significant influence over the company's initial shareholder base.
They provide analyst coverage. The bank's research analysts initiate coverage after the quiet period ends, providing ongoing fundamental analysis that institutional investors use to evaluate and hold the stock. Strong analyst coverage from well-regarded banks directly supports post-IPO stock performance.
They stabilize the price. After pricing, the lead underwriter can use the overallotment option (greenshoe) — the right to purchase up to 15% additional shares — to stabilize the stock price in the early days of trading by covering their short position in the open market.
The Syndicate Structure — Roles and Economics
Most IPOs involve a syndicate of multiple investment banks with clearly defined roles and economic splits. Understanding the structure helps management negotiate terms and set expectations about how the deal will be managed.
Lead Left Bookrunner
The lead left bookrunner is the dominant bank — the one whose name appears leftmost in the tombstone announcement. They control the bookbuild, set the price range, allocate shares, and manage the green shoe. They bear the most responsibility and receive the largest share of the underwriting spread — typically 50–70% of the total fee on a two-bank deal.
This is the single most important hiring decision in the underwriting process. The lead left's institutional sales force, research franchise, and investor relationships determine the quality of the book.
Lead Right / Co-Lead Bookrunner
The second bookrunner contributes their institutional investor relationships and sales capacity to the bookbuild. They provide diversification of investor access — reaching accounts the lead left bank may not cover as deeply. On a $300M+ offering, two bookrunners is standard; larger offerings may have three or four.
The lead right typically receives 25–45% of the underwriting spread. Their research analyst franchise is nearly as important as the lead left — two strong research voices post-IPO sustain more durable institutional interest.
Co-Managers
Co-managers appear in the syndicate in smaller roles — typically 3–5 banks for a mid-size IPO. They receive small economic allocations (1–5% each) and contribute niche investor relationships — sector specialists, regional accounts, or specific international investors. Co-managers often include smaller boutique banks with specialized research coverage in the company's sector.
Their post-IPO research coverage adds breadth to analyst coverage and can be disproportionately valuable for reaching niche investor audiences that large banks do not prioritize.
Underwriting Economics — What Banks Get Paid
The underwriting spread — typically 5–7% of gross IPO proceeds — is the primary compensation for the underwriting syndicate. On a $300M IPO with a 6% spread, total underwriting fees are $18M, split among all banks in the syndicate according to agreed percentages.
| Component | Typical Structure | Notes |
|---|---|---|
| Gross Spread | 5–7% of gross proceeds (most commonly 6–7% for U.S. IPOs) | All-in fee covering all underwriting services. Paid at closing from IPO proceeds. Non-negotiable below 5% for most deals; occasionally 5–5.5% for very large offerings ($1B+) |
| Management Fee | ~20% of gross spread | Paid to bookrunners for managing the offering process — S-1 review, investor targeting, pricing, allocation. Split among bookrunners per agreed percentages |
| Underwriting Fee | ~20% of gross spread | Paid proportionally to all syndicate members for underwriting commitment. Reflects the risk assumed by guaranteeing to purchase the offered shares |
| Selling Concession | ~60% of gross spread | Largest component — paid to the banks that actually sell shares to investors. Bookrunners that build the most orders receive the most selling concession, creating strong incentives for active selling |
| Greenshoe / Overallotment | 15% additional shares | Lead bookrunner has the right (not obligation) to purchase up to 15% additional shares at the IPO price within 30 days. Used for price stabilization. Generates additional fee income for the lead if exercised |
How to Evaluate Underwriters — The Five Criteria That Matter Most
Institutional Investor Relationships in Your Sector
The lead bookrunner's value is ultimately their access to the institutional investors who will own your stock. Ask every bank to show you specifically which long-only funds and fundamental investors they have placed IPOs with in your sector in the last 24 months — and what those investors' current positions are. A bank with strong relationships in consumer technology investors may be the wrong lead for an industrials company, regardless of their overall prestige.
Research Analyst Quality and Coverage Commitment
The bank's equity research analyst who will cover your stock post-IPO is one of the most important members of your extended public markets team. Evaluate the analyst's franchise — their Institutional Investor ranking, the quality of their research, and the investor base they influence. A top-ranked analyst in your sector can be worth more to post-IPO stock performance than any other single factor in the underwriter selection.
Recent IPO Execution Track Record
Ask for the bank's IPO performance data for the last 18–24 months — specifically: (a) how many of their IPOs priced above the range, within the range, and below the range; (b) average first-day performance; and (c) average 6-month and 12-month stock performance. Banks with strong recent IPO track records — in your deal size range and sector — are empirically better positioned to deliver strong outcomes.
Team Quality and Continuity Commitment
The managing director presenting in the bake-off is often not the banker who will run the day-to-day process. Ask explicitly who will be your day-to-day contact, who will be in the S-1 drafting sessions, who will attend roadshow prep, and who is responsible for the order book during the roadshow. Get commitment on continuity — banker turnover during an IPO process is a real and damaging risk.
Valuation View and Equity Story Framing
Different banks will frame your equity story differently and arrive at meaningfully different valuation opinions. A bank that sees you as a high-growth SaaS company may produce a very different valuation range than one that frames you as a legacy software business. The bank's view of your business — and their ability to convince institutional investors to share that view — has a direct impact on your offering price. Ask each bank to walk you through their valuation methodology in detail, including comparable company selection and adjustments.
The Bake-Off Process — How to Run It
The "bake-off" or "beauty contest" is the formal process by which management interviews potential underwriters and makes its selection. It is one of the most important management activities in the 12–18 months before the IPO and deserves careful preparation.
Prepare the Invitation List — Typically 6–8 Banks
Working with M&A or IPO advisors, identify the banks with the strongest combination of sector expertise, institutional investor relationships, and research franchise for your specific company. Include 2–3 bulge bracket candidates, 2–3 strong sector-specialist banks, and potentially 1–2 boutiques with exceptional coverage in your niche. Budget 3 hours per bank presentation in your calendar.
Distribute the Presentation Request — The "Pitch Parameters"
Send each bank a standardized set of materials and questions to ensure comparability of presentations. Provide the same business overview, financial summary, and ask each bank to present: their view of the equity story, comparable company analysis and valuation, proposed syndicate structure, targeted investor list, and the research analyst's preliminary view of the company. A 60–90 minute presentation followed by 30 minutes of Q&A is typical.
Conduct the Presentations — CEO and CFO Both Present
Both the CEO and CFO should be present for all bake-off presentations. The CEO evaluates cultural fit and investor story; the CFO evaluates financial analysis rigor, valuation methodology, and the banker's understanding of the financial model. After each presentation, debrief immediately before the next one while impressions are fresh. Score each bank on the criteria that matter most to your company.
Negotiate Economics and Engagement Terms
After selecting lead bookrunner and co-bookrunner candidates, negotiate the economics — underwriting spread, management fee split, and co-manager allocations. The spread is relatively standard (5.5–7%) but the fee split among banks is negotiable. Agree explicitly on banker and analyst continuity commitments, testing-the-waters meeting approach, and roadshow structure before signing engagement letters.
Sign Engagement Letters and Begin S-1 Process
Engagement letters are signed with all bookrunners. The S-1 drafting process begins immediately — an organizational meeting is held with all advisors to align on timeline, section responsibilities, and key issues. The underwriters' legal counsel (underwriter counsel) begins their own diligence process on the company.
Questions to Ask Every Bank in the Bake-Off
On Investor Relationships
On Research Coverage
On Execution and Team
On Valuation and Pricing
⚠️ Common Underwriter Selection Mistakes
- Choosing the bank with the highest valuation opinion — banks are incentivized to win the engagement; aggressive valuation views in the bake-off frequently convert into lower pricing expectations once the roadshow reveals actual market demand
- Selecting based on prestige rather than sector fit — the "best bank in the world" may not have the best institutional investor relationships or research franchise for your specific sector
- Not meeting the research analyst before selection — the analyst is one of the most important post-IPO relationships; selecting without meeting them is a significant oversight
- Failing to get continuity commitments in writing — verbal commitments about which banker will run your process are worth nothing unless they are in the engagement letter
- Choosing a co-manager for relationship reasons without evaluating their research franchise — a co-manager who cannot initiate meaningful research coverage adds limited post-IPO value
Underwriter Selection — Notable Cases
Snowflake — Goldman + Morgan Stanley Dual Lead (2020)
Snowflake's September 2020 IPO used Goldman Sachs and Morgan Stanley as joint lead managers — the most prestigious two-bank pairing in US investment banking. The selection reflected Snowflake's tier-one positioning and its access to the most coveted institutional investor relationships. Both banks had strong enterprise software research analysts (Katie Huberty at Morgan Stanley, who had covered cloud infrastructure extensively, and Goldman's software team) who would initiate coverage after the 25-day quiet period. The joint lead structure also meant that Snowflake had access to both banks' institutional distribution — their combined long-only fund relationships were the largest in the market. The decision to use two co-equals rather than a "Goldman lead, Morgan Stanley left" structure (where one bank has slightly higher billing and economic share) reflected Snowflake's leverage in the bake-off and the competitive pressure both banks applied to win the mandate.
Arm — 28-Bank Syndicate (2023)
Arm's September 2023 IPO used a syndicate of 28 banks — one of the largest ever assembled for a US IPO. The lead managers were Goldman Sachs, JPMorgan, Barclays, and Mizuho. The large syndicate served a specific purpose: SoftBank wanted to maximize Arm's post-IPO shareholder distribution globally, ensuring that institutions across the US, Europe, and Asia all had allocations and therefore had ongoing reasons to follow the stock and maintain research coverage. Mizuho's inclusion as a co-lead (rather than just a bookrunner) reflected the importance of Japanese institutional investors in the deal, given SoftBank's Japanese corporate identity and the significant Japanese pension and insurance fund appetite for the offering. The 28-bank structure also meant significant fee revenue was distributed broadly, which incentivized a large number of sell-side sales forces to actively market the deal to their institutional clients.
WeWork — Goldman Withdrew as Lead (2019)
WeWork's planned IPO originally included Goldman Sachs and JPMorgan as co-lead managers. As the S-1 was filed and the market reaction turned sharply negative, Goldman Sachs reduced its public involvement in the transaction — a highly unusual development in which an investment bank effectively distanced itself from a deal it had agreed to lead. JPMorgan maintained its role and provided the emergency credit facility that kept WeWork operational after the IPO was cancelled. The Goldman withdrawal (more accurately, a significant reduction in its visible involvement) was read by the market as a signal of how serious the problems with the offering had become — when one of the two lead banks signals reluctance, institutional investors who respected Goldman's judgment took note. The WeWork case is cited by ECM practitioners as an example of the reputational stakes for lead underwriters: being associated with a failed or fraudulent IPO has long-lasting consequences for the bank's relationship with institutional investors who trusted its judgment.
