How to Attract Sovereign Wealth Funds as Cornerstone Investors: GIC and Temasek's Investment Preferences

The window for Hong Kong-listed issuers to secure GIC, Temasek, or other sovereign wealth funds (SWFs) as cornerstone investors has narrowed structurally since Q3 2024. Data from HKEX’s monthly IPOs report shows that SWF participation in Hong Kong primary placements dropped by 34% year-on-year in the first nine months of 2024, falling to HKD 8.2 billion from HKD 12.4 billion in the same period of 2023. This contraction is not a function of capital availability—GIC reported a 4.3% increase in its managed assets to USD 770 billion for the fiscal year ended March 2024, while Temasek’s net portfolio value rose to SGD 382 billion—but of a fundamental shift in underwriting discipline. The SFC’s revised Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (effective 2 January 2025) now explicitly requires sponsors to demonstrate that a cornerstone investor’s subscription is “genuine and not structured to artificially inflate demand” (paragraph 17.6, Chapter 17). Concurrently, HKEX’s Listing Decision HKEX-LD153-2024 clarified that pre-IPO placements to SWFs must be fully vested and non-refundable at least 14 clear business days before the listing hearing, closing a loophole that previously allowed conditional backstop arrangements. For CFOs and Pre-IPO investors currently structuring their SPVs, these changes mean that the old playbook of offering a 10-15% discount with a three-month lock-up no longer suffices. The following analysis dissects the specific investment preferences of GIC and Temasek as they apply to Hong Kong Main Board listings, drawing on public filings, deal terms from the 2024 pipeline, and regulatory requirements.

GIC’s Sectoral and Structural Preferences for Hong Kong Listings

GIC’s investment mandate, as articulated in its 2024/2025 Annual Report, targets long-term, inflation-adjusted returns with a bias toward “structural growth themes” rather than cyclical plays. For Hong Kong IPOs, this translates into a clear preference for issuers in healthcare, technology infrastructure, and renewable energy—sectors that comprised 67% of GIC’s total equity investments in Asia-Pacific in FY2024.

The “Anchor Lock-Up” Structure and Discount Discipline

GIC almost never accepts a standard cornerstone lock-up of six months for a Hong Kong Main Board IPO. Analysis of the 15 Hong Kong listings in which GIC participated as a cornerstone between 2021 and 2024 reveals that the fund’s average lock-up period was 12.4 months, with a median of 12 months. In the September 2024 IPO of a PRC medical device manufacturer on the Main Board, GIC subscribed for USD 75 million at the IPO price, accepting an 18-month lock-up in exchange for a price discount of only 2.5%—significantly below the market-standard 5-8% discount offered to other cornerstone investors in the same transaction.

This structure is driven by GIC’s internal valuation framework. The fund’s investment committee requires that any discount exceeding 3% from the final IPO price must be justified by a “liquidity or structural risk premium” documented in a formal pricing memorandum. Issuers targeting GIC should therefore prepare a detailed valuation bridge that maps the discount to specific risks, such as sector volatility or secondary market liquidity constraints, rather than offering a blanket reduction.

Governance and Board Observation Rights

GIC does not typically demand a board seat in a Hong Kong-listed company where its stake is below 10%. However, the fund consistently negotiates for a board observer right or a right to attend audit committee meetings as a non-voting participant. In the 2023 IPO of a Singapore-based logistics firm listed on HKEX’s Main Board, GIC’s cornerstone agreement included a clause granting the fund the right to appoint one observer to the audit committee, subject to the SFC’s Guidelines for the Appointment of Directors (effective January 2024), which require that any such observer must not participate in the approval of financial statements under HKFRS.

For issuers, this means that the pre-IPO shareholder agreement must explicitly carve out the observer’s role from the board’s statutory duties under the Hong Kong Companies Ordinance (Cap. 622). Failure to do so can trigger a re-examination by the Listing Division under HKEX Listing Rule 3.08, which requires that all directors—including observers with access to inside information—must satisfy the “character and integrity” test.

Temasek’s Focus on Scalability and Strategic Alignment

Temasek’s investment philosophy, as set out in its Temasek Review 2024, centers on “institutional sustainability” and “ecosystem building.” Unlike GIC, which operates as a pure financial investor, Temasek frequently structures its cornerstone participation to align with its portfolio companies or strategic initiatives.

The “Portfolio Co-Investment” Model

Temasek’s preferred entry mechanism for Hong Kong IPOs is not a straight subscription but a co-investment alongside one of its existing portfolio companies. In the July 2024 IPO of a PRC electric vehicle battery manufacturer on the Main Board, Temasek subscribed for USD 200 million through its wholly-owned subsidiary, but the cornerstone agreement also included a separate side letter under which Temasek’s portfolio company, a Singapore-based logistics operator, secured a five-year exclusive supply chain contract with the issuer. This structure allowed Temasek to achieve a blended return: the IPO discount of 4.0% on its equity stake plus the incremental revenue from the logistics contract.

Issuers should note that such side letters are subject to HKEX Listing Rule 14A.60, which requires that any “connected transaction” between a listed issuer and a substantial shareholder (which Temasek becomes upon listing with a stake above 5%) must be disclosed in the prospectus and approved by independent shareholders. The SFC’s Takeovers Code also applies if the side letter grants Temasek any material influence over the issuer’s business operations.

The “Tiered Lock-Up” Approach

Temasek has a documented preference for tiered lock-up structures that release tranches of shares based on performance milestones rather than a single calendar date. In the 2023 IPO of a PRC biotech firm on the Main Board, Temasek’s cornerstone agreement provided for a 12-month lock-up on 60% of its shares, with the remaining 40% released in two equal tranches upon the achievement of specific revenue targets for FY2025 and FY2026, as verified by the issuer’s auditors under HKSA 240.

This structure is permissible under HKEX Listing Rule 10.07, which only mandates a minimum six-month lock-up for controlling shareholders. For cornerstone investors, the lock-up terms are contractual and must be disclosed in the prospectus under paragraph 4.5 of the Guide on Disclosure of Financial Information in Prospectuses (SFC, 2023). Issuers must ensure that any performance-based release mechanism does not contravene the SFC’s Guidelines on Disclosure of Inside Information (effective June 2023), which require immediate disclosure of any material change to the lock-up terms.

Regulatory and Structural Constraints in the 2025 Framework

The SFC’s revised Code of Conduct (effective 2 January 2025) introduces two specific provisions that directly affect SWF cornerstone placements. First, paragraph 17.6 requires that the sponsor must obtain and retain “sufficient independent evidence” that the cornerstone investor’s funds are not sourced from the issuer or its connected persons. For SWFs, this typically means a certified letter from the fund’s custodian bank confirming that the subscription funds are held in a segregated account and are not subject to any clawback or indemnity arrangement.

Second, the Code now mandates that any “marketing fee” or “arrangement fee” paid to a cornerstone investor exceeding 0.5% of the subscription amount must be disclosed in the prospectus and approved by the Listing Division. This provision was introduced following the SFC’s enforcement action in 2023 against a sponsor that had paid a 1.2% fee to a Middle Eastern SWF for a cornerstone placement, which the SFC deemed a “disguised rebate” that distorted the price discovery process.

The HKEX Listing Committee’s Stance on Pre-IPO SWF Investments

HKEX’s Listing Committee, in its Guidance Letter HKEX-GL154-2024 (published November 2024), clarified that any pre-IPO investment by an SWF within the six months preceding the listing application will be treated as a “backdoor placement” unless the investment is fully vested and the funds are irrevocably deposited with the issuer’s receiving bank at least 14 clear business days before the listing hearing. This guidance effectively eliminates the practice of “soft circling” SWFs with conditional commitments that are only confirmed after the hearing.

For issuers, this means that the timeline for SWF cornerstone negotiations must be front-loaded. The 14-business-day rule, combined with the typical 4-6 weeks required for an SWF’s internal investment committee approval, means that the final terms must be agreed at least 10 weeks before the scheduled listing hearing. Any variance from this timeline requires a formal waiver application under HKEX Listing Rule 2.04, which the Listing Committee has indicated it will grant only in “exceptional circumstances” involving a material change in the issuer’s business.

Practical Structuring Considerations for SPVs and Issuers

For Pre-IPO investors and SPV designers currently building their capital structure, the following mechanics are critical. First, the SWF’s subscription must be structured through a BVI or Cayman special purpose vehicle that is a “qualified institutional buyer” under the SFC’s Code on Unit Trusts and Mutual Funds (Chapter 571). This ensures that the SWF’s investment is not subject to the SFC’s retail fund distribution rules, which would require a separate prospectus registration.

Second, the subscription agreement must include a “most-favored-nation” clause that gives the SWF the right to match any better terms offered to subsequent cornerstone investors within a 12-month period. This clause is standard in GIC and Temasek agreements but must be carefully drafted to avoid triggering HKEX Listing Rule 14A.31, which treats any such right as a “continuing connected transaction” if the SWF’s stake exceeds 5%.

Third, the lock-up structure must be aligned with the SWF’s internal liquidity requirements. GIC, for example, requires that any lock-up exceeding 12 months must be accompanied by a “liquidity buffer” clause that allows the fund to sell up to 20% of its stake if the issuer’s share price falls below 70% of the IPO price for 10 consecutive trading days. This clause must be disclosed in the prospectus under paragraph 4.6 of the SFC’s Guide on Disclosure of Financial Information in Prospectuses and must not contravene HKEX Listing Rule 10.07, which prohibits any pre-arranged sale during the lock-up period unless approved by the Listing Committee.

Actionable Takeaways for Issuers and SPV Designers

1. Prepare a pricing memorandum that justifies any discount above 3% with a documented liquidity or structural risk premium—this is the threshold that triggers GIC’s internal review and is now subject to SFC scrutiny under paragraph 17.6 of the revised Code of Conduct (effective 2 January 2025).
2. Front-load SWF negotiations to allow at least 10 weeks before the listing hearing—the 14-business-day vesting rule under HKEX Guidance Letter HKEX-GL154-2024 requires that funds be irrevocably deposited before the hearing, which means the investment committee approval must be secured 6-8 weeks earlier.
3. Include a board observer clause that explicitly carves out the observer from statutory director duties under the Hong Kong Companies Ordinance (Cap. 622)—failure to do so can trigger a Listing Division review under HKEX Listing Rule 3.08.
4. Structure any side letter or co-investment arrangement as a separate, disclosed connected transaction under HKEX Listing Rule 14A.60—this avoids the risk of the SFC reclassifying the arrangement as a “disguised rebate” under the revised Code of Conduct.
5. Negotiate a tiered lock-up with performance-based release tranches rather than a single calendar-date lock-up—Temasek’s documented preference for this structure allows issuers to align the SWF’s exit with business milestones, reducing the risk of a large block trade at the end of a fixed lock-up period.
