How to Choose an IPO Underwriter: Five Criteria for Evaluating Investment Bank Capabilities

The selection of an IPO underwriter has shifted from a relationship-driven decision to a compliance-weighted one, following the SEC’s finalised amendments to Rule 10b-5 liability standards for gatekeepers in late 2024 and the PCAOB’s 2025 enforcement focus on foreign issuer audits. For Hong Kong-based companies and cross-border sponsors eyeing a NYSE or NASDAQ listing, the margin for error in underwriter diligence has narrowed significantly. The SEC’s Division of Corporation Finance reported a 34% increase in deficiency letters related to underwriter due diligence procedures in the first half of 2025 compared to the same period in 2023. This regulatory tightening coincides with a resurgence in US IPO volume: 147 listings raised USD 38.2 billion on US exchanges in 2024, according to data from the NYSE and NASDAQ, and the first quarter of 2025 has already seen 41 offerings with aggregate proceeds of USD 9.7 billion. Against this backdrop, evaluating an investment bank’s capabilities requires a structured framework that goes beyond league table rankings. The following five criteria provide a systematic approach for CFOs and company secretaries to assess whether a bulge bracket, a mid-market specialist, or a boutique sponsor is the correct fit for their specific deal profile.

Criterion One: Sector-Specific Execution Track Record

Deal Volume in the Issuer’s Industry Vertical

An underwriter’s general league table position is a poor proxy for its ability to price and distribute a deal in a specific sector. The relevant metric is the number of IPOs completed in the issuer’s GICS sub-industry over the preceding 24 months, measured by both count and total proceeds. For example, a biotechnology company seeking a NASDAQ listing should examine the underwriter’s involvement in NASDAQ-listed biotech IPOs since January 2023. According to Dealogic data, the top five banks by biotech IPO count in that period accounted for 62% of all such offerings, but the bank ranked sixth by volume had a 100% execution rate for deals under USD 100 million—a more relevant statistic for a mid-cap issuer.

Aftermarket Performance of Comparable Deals

The underwriter’s track record should be evaluated not only on the IPO price and first-day pop but on the 90-day and 180-day post-listing performance of its sector-specific deals. A study published by the NYSE in 2024 found that deals led by underwriters with a concentrated sector focus experienced 12% less volatility in the first 180 trading days compared to those led by generalist syndicates. Issuers should request the underwriter’s pricing range versus actual offer price for the last five comparable transactions, as well as the percentage of deals that closed below the offer price at the end of the first quarter of trading.

Criterion Two: Distribution Network and Institutional Investor Access

Quality of Institutional Book Composition

The composition of the underwriter’s institutional book is more important than its size. An issuer should require the potential underwriter to provide a breakdown of its last three IPOs by investor type: long-only funds (e.g., Fidelity, Capital Group), hedge funds, sovereign wealth funds, and retail aggregators. The Hong Kong Securities and Futures Commission’s Code of Conduct for Persons Licensed by or Registered with the SFC (paragraph 17.6) mandates that sponsors in Hong Kong exercise due diligence to ensure that the placing and distribution of securities are conducted in a manner that is fair and orderly. While this code applies to Hong Kong-licensed sponsors, the principle of verifying the quality of the book is directly transferable to US listings. A book with over 40% hedge fund participation typically signals higher volatility in the aftermarket, as these investors are more likely to flip shares within the first 30 days.

Geographic and AUM Distribution of the Investor Base

For a Hong Kong-headquartered company listing in the US, the underwriter’s ability to attract US-based institutional capital is critical. The issuer should request a geographic breakdown of the underwriter’s investor base for its last three cross-border IPOs. A bank that consistently places 60% or more of its allocation with US-based accounts—as opposed to Asian or European accounts—demonstrates stronger domestic demand, which tends to support post-listing price stability. The SEC’s Regulation M (Rule 101) prohibits underwriters from bidding for or purchasing the offered security during the restricted period, but the quality of the institutional book built before the pricing date is a direct function of the bank’s distribution network.

Criterion Three: Pricing Discipline and Valuation Support

Track Record of Final Pricing Within the Range

An underwriter’s pricing discipline is measured by the percentage of its IPOs that price within the initial filing range. Data from the SEC’s EDGAR system for 2024 shows that the top 10 underwriters by proceeds priced 78% of their deals within the range, compared to 62% for banks ranked 11th to 25th. An issuer should ask for the underwriter’s specific percentage for deals in its sector and market capitalisation bracket. A bank that consistently prices at the top of the range may indicate aggressive marketing, but it also carries the risk of a subsequent price decline if the initial demand was overstated.

Valuation Methodology and Comparable Company Analysis

The underwriter’s valuation team should present a detailed comparable company analysis (CCA) and discounted cash flow (DCF) model during the bake-off process. The CCA must include at least five publicly traded peers with similar revenue profiles, growth rates, and margins. The issuer should verify that the underwriter’s valuation range is consistent with the current trading multiples of those peers. For example, if the selected peers trade at an average EV/Revenue multiple of 5.0x for the trailing twelve months, the underwriter’s proposed IPO valuation range should fall within 0.8x to 1.2x of that multiple, unless a clear premium is justified by superior growth or margin profile. The HKMA’s Supervisory Policy Manual on risk management (CA-S-1) emphasises the importance of independent valuation processes; the same principle applies to the underwriter’s valuation work in a US listing context.

Criterion Four: Research Coverage and Post-IPO Analyst Support

Quality and Independence of the Research Department

Post-IPO analyst coverage is a key determinant of secondary market liquidity. The issuer should evaluate the underwriter’s equity research department based on the number of analysts covering the issuer’s industry, the average tenure of those analysts, and the accuracy of their earnings estimates over the past 24 months. The SEC’s Regulation AC (Analyst Certification) requires analysts to certify that the views expressed in their reports accurately reflect their personal views, and the issuer should verify that the underwriter has no history of SEC or FINRA enforcement actions related to research independence. A study by the CFA Institute in 2024 found that IPOs with at least three sell-side analysts initiating coverage within 90 days of listing had 23% higher average daily trading volume in the subsequent six months.

Initiation Coverage Commitment and Timeline

The underwriter should commit in the engagement letter to initiating research coverage within 30 days of the listing date. The issuer should also request the underwriter’s track record of maintaining coverage for at least 12 months post-IPO. Data from FINRA’s TRACE system shows that 18% of IPOs from 2022 to 2024 lost all sell-side coverage within the first year, with the highest rate of coverage drop-off occurring among banks that ranked outside the top 15 by research department headcount. The underwriter’s research budget and the number of analysts dedicated to the issuer’s sector are therefore material factors in the selection process.

Criterion Five: Legal and Regulatory Compliance History

SEC and FINRA Enforcement Actions

The underwriter’s regulatory history is a direct indicator of its internal controls and risk management culture. The issuer should conduct a search of the SEC’s administrative proceedings database and FINRA’s enforcement actions database for the preceding five years. Specific attention should be paid to actions related to IPO allocations, underwriting due diligence failures, or violations of Regulation M. According to the SEC’s 2024 Annual Report, the Division of Enforcement brought 784 actions in fiscal year 2024, of which 112 involved broker-dealers or underwriters. An underwriter with more than two enforcement actions in the past three years related to underwriting practices should be subject to enhanced scrutiny.

Due Diligence Procedures and Document Retention

The SFC’s Code of Conduct (paragraph 17.2) requires sponsors in Hong Kong to conduct reasonable due diligence to ensure that the listing document contains all material information. While this code applies to Hong Kong listings, the SEC’s Rule 10b-5 and the Securities Act of 1933 impose similar obligations on US underwriters. The issuer should request the underwriter’s due diligence checklist and document retention policy as part of the selection process. A bank that cannot provide a standardised due diligence framework—covering areas such as revenue verification, legal compliance, intellectual property ownership, and related-party transactions—raises a material red flag. The PCAOB’s 2025 inspection reports have specifically highlighted deficiencies in audit documentation related to revenue recognition for foreign issuers, and the underwriter’s due diligence procedures should be designed to cross-reference these audit findings.

Actionable Takeaways

1. Require the underwriter to provide a sector-specific execution track record covering the last 24 months, including the 90-day and 180-day aftermarket performance of comparable deals, not just the first-day pop.
2. Verify the underwriter’s institutional book composition for its last three cross-border IPOs, demanding a breakdown by investor type and geography, with a target of at least 60% US-based institutional allocation.
3. Confirm that the underwriter’s proposed valuation range falls within 0.8x to 1.2x of the current trading multiples of at least five publicly traded comparable companies.
4. Secure a contractual commitment in the engagement letter for research initiation within 30 days of listing and a minimum of 12 months of continued coverage.
5. Conduct a regulatory history search across SEC and FINRA databases for the preceding five years, and request the underwriter’s standardised due diligence checklist and document retention policy before signing the engagement letter.
