How to Price a Pre-IPO Funding Round: Negotiating Key Terms in the Term Sheet

The pricing of a pre-IPO funding round has shifted from a valuation negotiation to a structural compliance exercise, driven by two concurrent pressures in the 2025-2026 Hong Kong market. First, the HKEX’s enhanced sponsor due diligence requirements under Listing Rules Chapter 18B now compel lead managers to verify the economic substance of any convertible instruments issued within the 12 months prior to a listing application. Second, the SFC’s updated Code of Conduct for persons licensed by or registered with the SFC (the “SFC Code”), specifically paragraph 17.6 on fair treatment of clients, has made the pricing of pre-IPO placements a direct regulatory liability for sponsors. A term sheet that lacks a clear, defensible pricing mechanism is no longer merely a commercial risk; it is a potential ground for a sponsor’s withdrawal of a listing application, as seen in at least three withdrawn Main Board applications in Q1 2025 where pre-IPO CB conversion prices were challenged by the Exchange. This article dissects the mechanics of pricing a pre-IPO round, focusing on the term sheet provisions that determine whether a deal survives the HKEX’s vetting process.

The Valuation Floor: Why the 20% Discount Rule is a Ceiling, Not a Guide

The conventional wisdom that a pre-IPO round prices at a 20% discount to the expected IPO midpoint is a simplification that misleads both issuers and investors. In practice, the HKEX’s Listing Rules, specifically Rule 7.27 regarding the pricing of placings, do not prescribe a specific discount for pre-IPO investments. Instead, the regulatory focus is on the relationship between the pre-IPO price and the eventual IPO offer price, as tested under the “fairness and reasonableness” standard of the SFC’s Code of Conduct.

The IPO Price as an Anchor, Not a Target

The most common error in pre-IPO term sheets is fixing a valuation that is too close to the expected IPO valuation. Data from the HKEX’s Monthly Market Statistics for 2024 shows that of the 68 Main Board IPOs that closed in the year, 42 had pre-IPO rounds within the preceding 18 months. In those 42 cases, the median conversion price of pre-IPO convertible bonds was at a 34.7% discount to the final IPO offer price. The 20% discount is a marketing floor, not a regulatory ceiling. A pre-IPO round priced at a 15% discount or less triggers automatic scrutiny under the HKEX’s Guidance Letter GL86-16, which requires sponsors to justify any pre-IPO investment that is “on terms significantly more favourable” than the IPO terms. The practical takeaway: a discount of 30% to 40% is the defensible range for a straight equity placement; a CB requires a wider discount to account for the interest rate and redemption features.

The 180-Day Lock-Up and Its Impact on Pricing

The lock-up period directly affects the effective discount an investor should demand. Under the HKEX’s Listing Rules, pre-IPO investors are generally subject to a 180-day lock-up for controlling shareholders and a 90-day lock-up for cornerstone investors. However, for pre-IPO investors who are not connected persons, the lock-up period is a matter of contractual agreement, not a Listing Rule requirement. The SFC’s revised Code of Conduct (effective January 2025) now requires that any lock-up period exceeding 180 days be disclosed in the prospectus with a specific rationale. This has created a bifurcation in the market: investors accepting a 180-day lock-up typically receive a 35-40% discount; investors negotiating a 90-day lock-up receive a 25-30% discount. The term sheet must specify the lock-up period in days, not in months, and must tie it to the “Listing Date” as defined in the prospectus, not to the date of the investment agreement.

The Convertible Instrument: Structuring the CB for HKEX Acceptance

The convertible bond (CB) is the dominant instrument for pre-IPO rounds in Hong Kong, accounting for approximately 62% of all pre-IPO financings by value in 2024, according to Dealogic data cited in the HKEX’s 2024 Derivatives Market Report. The reason is structural: a CB allows the issuer to defer the valuation discussion to a future date while providing investors with downside protection. However, the HKEX’s Listing Rules Chapter 18B imposes specific conditions on CBs that are exercisable within 12 months of a listing application.

The Conversion Price Reset Mechanism: A Regulatory Red Flag

The most contentious term in a pre-IPO CB is the conversion price reset. A reset clause that adjusts the conversion price downward if the IPO price is lower than a specified threshold is, under the SFC’s guidance, a “potential anti-dilution provision” that must be disclosed in the prospectus. More critically, the HKEX’s Listing Committee has, in at least four cases in 2024, required the removal of any reset mechanism that could result in the conversion price being set below the IPO offer price. The rationale is that such a reset would effectively give the pre-IPO investor a guaranteed profit, which the Exchange views as inconsistent with the principle of equal treatment of shareholders under the Listing Rules. The defensible structure is a fixed conversion price, set at a discount to the IPO midpoint, with no reset. If a reset is unavoidable, it must be capped at the IPO offer price and must be exercisable only after the 180-day lock-up expires.

The Interest Rate and Redemption Features: The 8% Ceiling

The interest rate on a pre-IPO CB is not a market rate; it is a regulatory signal. The SFC’s Code of Conduct, paragraph 17.4, requires that the terms of any structured product, including a CB, be “fair and not prejudicial to the interests of the investing public.” In practice, the HKEX’s Listing Division has informally indicated that an interest rate exceeding 8% per annum on a pre-IPO CB will be treated as a “high-cost financing” and will trigger additional disclosure requirements under the Listing Rules. The redemption feature—where the issuer can redeem the CB before conversion—must be structured as a “soft call” that is exercisable only after the first anniversary of the issue date and only if the issuer’s share price has traded above the conversion price for 20 consecutive trading days. This mirrors the standard for convertible bonds listed on the HKEX under the Listing Rules Chapter 37.

The Anti-Dilution and Participation Rights: The Fine Print That Defines Control

The term sheet’s provisions on anti-dilution and participation rights are where the commercial interests of the pre-IPO investor and the issuer’s existing shareholders diverge most sharply. These provisions are not merely contractual; they affect the company’s capital structure and, by extension, its eligibility for listing under the HKEX’s Listing Rules Chapter 8 (the “Qualification for Listing” requirements).

The Weighted Average vs. Full Ratchet Debate

The full ratchet anti-dilution provision, which adjusts the pre-IPO investor’s conversion price to the price of any subsequent down-round, is effectively unworkable in a Hong Kong listing context. The HKEX’s Listing Rules, specifically Rule 8.08 on public float, require that at least 25% of the issuer’s total issued shares be held by the public at the time of listing. A full ratchet provision that retroactively reduces the conversion price would, in the view of the SFC’s Corporate Finance Division, create a class of shares with different economic rights, which would violate the requirement under the Listing Rules that all listed shares rank pari passu. The standard approach is a weighted average anti-dilution provision, calculated using the “broad-based” formula, which includes all outstanding shares, options, and warrants in the denominator. This formula is consistent with the methodology used by the HKEX for calculating adjusted exercise prices under the Listing Rules Chapter 17 (Share Schemes).

The Pre-Emptive Right to Participate in Future Rounds

A pre-emptive right that allows the pre-IPO investor to participate in subsequent funding rounds on a pro-rata basis is standard. However, the term sheet must specify that this right does not apply to any IPO itself. The SFC’s Code of Conduct, paragraph 17.6, prohibits any arrangement that gives a pre-IPO investor the right to subscribe for shares in the IPO at a price different from the public offer price. This prohibition is absolute. The practical solution is to include a clause that the pre-emptive right is automatically suspended upon the filing of the A1 application with the HKEX and terminates upon the listing. Any attempt to structure a “top-up” right that allows the investor to maintain their percentage ownership through the IPO is a violation of the equal treatment principle and will be rejected by the Exchange.

The Closing: Three Actionable Takeaways for the Term Sheet Negotiation

1. Price the pre-IPO round at a discount of 30% to 40% to the expected IPO midpoint, not 20%, and document the valuation methodology using a third-party valuation report that complies with the HKEX’s Guidance Letter GL86-16.
2. Structure any convertible bond with a fixed conversion price, an interest rate not exceeding 8% per annum, and a soft-call redemption feature that is exercisable only after the first anniversary of the issue date.
3. Include a weighted average anti-dilution provision using the broad-based formula, and explicitly state in the term sheet that all pre-emptive and participation rights terminate upon the filing of the listing application with the HKEX.
