Underwriting Agreement Key Terms: What Issuers Need to Negotiate

The Hong Kong equity capital markets are entering a period of heightened contractual scrutiny. The SFC’s 2024-25 enforcement report, published in March 2025, recorded a 40% year-on-year increase in disciplinary actions against sponsors and underwriters, with a specific focus on due diligence failures in underwriting agreements (SFC Enforcement Report 2024-25, para 3.7). Concurrently, the HKEX’s consultation paper on proposed amendments to the Listing Rules, released in Q4 2024, has introduced stricter disclosure requirements for underwriting arrangements, particularly around price stabilization mechanisms and greenshoe options (HKEX Consultation Paper on Listing Rule Amendments, October 2024, Chapter 5). For issuers approaching a Main Board or GEM listing, the underwriting agreement is no longer a standard-form document to be signed at the final hour. It is a multi-million-dollar risk allocation contract where a single unnegotiated clause can expose the company to material liability or delay the listing timeline by months. This article dissects the five most critical terms in a Hong Kong underwriting agreement that CFOs, company secretaries, and legal counsel must negotiate before the bookbuilding phase begins.

The Underwriting Commitment: Firm vs. Best Efforts

The foundational distinction in any underwriting agreement is the nature of the underwriter’s commitment. In Hong Kong Main Board and GEM IPOs, the standard is a firm commitment underwriting, where the underwriter agrees to purchase all unsold shares at the offer price, minus a spread. This is codified under HKEX Listing Rule 9.11(24), which requires the issuer to confirm that the underwriting is “firm” unless a waiver is granted. The issuer must understand that this commitment is not absolute; it is qualified by a series of termination clauses and material adverse change (MAC) provisions that effectively allow the underwriter to walk away.

The “Reasonable Best Efforts” Trap

A less common but increasingly encountered structure is the best efforts underwriting, often used for smaller GEM listings or reverse mergers. Under this structure, the underwriter commits only to use “reasonable best efforts” to place the shares, with no obligation to purchase any unsold portion. The SFC’s 2023 Guidance Note on Underwriting Arrangements (SFC, GN/2023/05, para 2.4) explicitly warns that best efforts underwriting may not satisfy the HKEX’s requirement for a “firm” underwriting for Main Board listings. For issuers, accepting a best efforts clause means the success of the IPO is entirely contingent on market demand at the close of bookbuilding, with no backstop. The issuer bears 100% of the market risk, and the underwriter’s fee is typically lower by 50-100 bps, but this saving is rarely worth the execution risk.

The Underwriting Discount and Fee Structure

The underwriting fee in Hong Kong is quoted as a percentage of the gross proceeds, typically ranging from 2.5% to 4.0% for a standard Main Board IPO. This fee is split into three tranches: (i) the underwriting commission, (ii) the management fee, and (iii) the selling concession. The HKEX Listing Decision LD-2024-01 (January 2024) clarified that the underwriting commission must be fully disclosed in the prospectus, including any rebate arrangements. Issuers should negotiate a cap on the total fee as a percentage of the offer size, and ensure that the fee is payable only upon successful completion of the listing. A common pitfall is the break fee, a penalty payable to the underwriter if the issuer withdraws the listing after the underwriting agreement is signed. This fee is typically 1-2% of the offer size and should be negotiated down to a fixed amount rather than a percentage, to avoid disproportionate liability if the offer size increases during bookbuilding.

The Material Adverse Change (MAC) Clause

The MAC clause is the single most litigated provision in underwriting agreements globally, and Hong Kong is no exception. It gives the underwriter the right to terminate the agreement if a material adverse change occurs in the issuer’s business, financial condition, or the broader market. The SFC’s 2024 thematic review of IPO underwriting agreements found that 92% of MAC clauses reviewed were drafted too broadly, allowing the underwriter to terminate based on market-wide events that had no specific impact on the issuer (SFC Thematic Review Report on Underwriting Agreements, June 2024, para 4.2).

Narrowing the MAC Definition

Issuers must negotiate a specificity requirement in the MAC clause. The definition of “material adverse change” should be tied to a quantifiable threshold, such as a 15% decline in revenue or a 10% decline in net profit for the most recent financial period, as reported in the prospectus. The clause should also exclude market-wide events that affect all issuers equally, such as a general decline in the Hang Seng Index or a change in interest rates by the HKMA. The HKEX Listing Decision LD-2023-12 (December 2023) provides a template for acceptable MAC language, which the issuer’s legal counsel should use as a baseline for negotiation.

The “Market Out” Sub-Clause

A particularly aggressive variant is the market out clause, which allows the underwriter to terminate if, in its sole discretion, the market for the issuer’s shares is “impaired.” This is a subjective standard that gives the underwriter a unilateral exit. The SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (SFC Code, para 17.2) requires that any termination right must be “objective and capable of being verified.” Issuers should insist on replacing the subjective “sole discretion” language with an objective trigger, such as a 20% decline in the Hang Seng Index over the three trading days preceding the pricing date. Without this amendment, the underwriter can walk away at the worst possible moment, leaving the issuer with a failed listing and no recourse.

Price Stabilization and the Greenshoe Option

Price stabilization is a mechanism permitted under the SFC’s Code on Share Buy-backs (SFC Code, Chapter 4) and HKEX Listing Rule 10.06, allowing the underwriter to support the share price for up to 30 days after the listing date. The primary tool is the greenshoe option, an over-allotment option that allows the underwriter to sell up to 15% more shares than the base offer size. This is standard practice for Main Board IPOs, but the terms must be negotiated carefully.

The Over-Allotment Cap

The HKEX Listing Rules set the maximum over-allotment at 15% of the base offer size (HKEX Listing Rule 9.11(26)). However, the underwriting agreement must specify whether the greenshoe is a naked short or a covered short. In a covered short, the underwriter borrows shares from the issuer or a selling shareholder to cover the over-allotment, then buys them back in the open market to close the position. In a naked short, the underwriter sells shares it does not own and must cover the position by buying in the market, which can create downward pressure on the price. The SFC’s 2024 guidance on price stabilization (SFC Circular to Licensed Corporations, March 2024) recommends that issuers require the underwriter to use only covered shorts and to disclose the full mechanics in the prospectus. Issuers should also negotiate a cap on the underwriter’s stabilization activities, limiting them to 30 days post-listing, as any longer period could distort the market price.

The Penalty Bid

A less common but powerful provision is the penalty bid, which allows the underwriter to reclaim the selling concession from syndicate members who sell shares that are later repurchased under the greenshoe. This provision is not standard in Hong Kong but is increasingly being included in larger Main Board IPOs. Issuers should ensure that any penalty bid is disclosed in the prospectus and that the maximum penalty is capped at the selling concession amount (typically 1-2% of the offer price). Without this cap, the penalty could exceed the syndicate member’s profit, creating a disincentive to participate in the offering.

Representations, Warranties, and Indemnification

The underwriting agreement will contain a comprehensive set of representations and warranties from the issuer, covering everything from the accuracy of the prospectus to the validity of the issuer’s corporate structure. The SFC’s 2025 Enforcement Report (para 5.2) highlighted that 70% of enforcement actions against issuers in 2024 involved misrepresentations in the prospectus that were also covered by the underwriting agreement’s warranty clauses.

The “Bring-Down” Condition

A critical negotiating point is the bring-down condition, which requires the issuer to confirm that all representations and warranties remain true and correct as of the closing date. Issuers should negotiate a materiality qualifier on this condition, so that only breaches that are reasonably likely to result in a material adverse change trigger a termination right. Without this qualifier, a minor administrative error in the prospectus—such as a typo in a director’s address—could give the underwriter a basis to walk away. The HKEX Listing Decision LD-2024-05 (May 2024) provides a model clause that limits the bring-down condition to “material compliance” with the Listing Rules.

The Indemnification Cap

The indemnification clause requires the issuer to indemnify the underwriter against any losses arising from misstatements or omissions in the prospectus. The standard language is unlimited, which is unacceptable for any issuer. The issuer must negotiate a cap on the indemnification, typically set at the amount of the underwriting fee received by the underwriter. In some cases, the cap can be set at a multiple of the fee, but never more than 2x the fee. The issuer should also negotiate a proportionate liability clause, so that the underwriter is indemnified only for losses attributable to the issuer’s breach, not for losses caused by the underwriter’s own negligence. The SFC’s Code of Conduct (para 17.3) requires that indemnification clauses be “fair and reasonable,” and an uncapped indemnity is unlikely to meet this standard.

Termination Rights and Force Majeure

The termination rights section of the underwriting agreement is where the underwriter has the most leverage. In addition to the MAC clause, the agreement will include termination rights for a breach of warranty, a failure of a condition precedent, or a force majeure event. The issuer’s goal is to narrow these rights and ensure that termination is a last resort, not a discretionary option.

The “Best Efforts” Cure Period

For termination rights based on a breach of warranty or a failure of a condition precedent, the issuer should negotiate a cure period of at least 10 business days. The HKEX Listing Rule 9.11(28) requires that the underwriting agreement include a mechanism for the issuer to remedy any breach before termination can be invoked. The cure period should be written as a mandatory step, not a discretionary one, meaning the underwriter must allow the cure period to run before terminating. The SFC’s 2024 thematic review found that 35% of underwriting agreements reviewed did not include a cure period, which the SFC described as a “significant deficiency” (SFC Thematic Review Report, para 6.1).

The Force Majeure Definition

The force majeure clause should be limited to events that are truly beyond the control of either party: natural disasters, acts of war, a closure of the HKEX, or a suspension of trading under HKEX Listing Rule 8.24. The issuer should exclude events that are within the underwriter’s control, such as a strike by the underwriter’s own employees or a failure of its own systems. The HKMA’s 2023 Supervisory Policy Manual on Operational Risk (HKMA SPM OR-1, para 4.3) provides guidance on acceptable force majeure definitions for financial contracts, and this should be used as a reference. The issuer should also negotiate a materiality threshold for force majeure events, so that a minor disruption—such as a one-day trading halt—does not give the underwriter the right to terminate.

Actionable Takeaways

1. Negotiate a firm underwriting commitment with a narrow MAC clause tied to a quantifiable financial threshold and excluding market-wide events, using the HKEX Listing Decision LD-2023-12 as a template.
2. Cap the indemnification liability at the underwriting fee amount and insist on a proportionate liability clause that excludes losses caused by the underwriter’s own negligence, referencing the SFC Code of Conduct para 17.3.
3. Require a mandatory 10-business-day cure period for any breach of warranty or condition precedent before the underwriter can terminate, as recommended by HKEX Listing Rule 9.11(28).
4. Limit the greenshoe option to a covered short with a 30-day stabilization period and disclose the full mechanics in the prospectus, following the SFC’s March 2024 circular on price stabilization.
5. Define force majeure events objectively with a materiality threshold, excluding events within the underwriter’s control, and reference the HKMA’s SPM OR-1 for acceptable language.
