SPAC vs IPO Post-Listing Analyst Coverage: Differences in Research Report Volume

The divergence in post-listing analyst coverage between SPAC mergers and traditional IPOs has become a material factor in valuation discovery for issuers and investors on the NYSE and NASDAQ. A September 2025 study by the SEC’s Division of Economic and Risk Analysis (DERA) found that companies listing via SPAC mergers in 2024 received an average of 4.2 sell-side research initiations within the first 12 months post-de-SPAC, compared to 8.7 for traditional IPOs of comparable market capitalisation in the same period. This 52% gap in coverage volume directly impacts liquidity, price stability, and institutional investor demand. For Hong Kong-based issuers and cross-border sponsors evaluating US listing routes, the coverage differential is not an academic curiosity but a structural consequence of differing regulatory frameworks, fee structures, and analyst incentive models. The SFC’s 2023 consultation paper on sponsor due diligence (SFC, 2023) highlighted that Hong Kong’s sponsor regime under the Listing Rules imposes a higher standard of ongoing responsibility on sponsors, which has no direct equivalent in the US SPAC structure. This article examines the specific mechanisms driving the coverage gap, the data behind it, and the actionable implications for issuers choosing between a traditional IPO and a SPAC merger on US exchanges.

The Structural Origins of Coverage Asymmetry

The coverage gap originates in the fundamental economics of the two listing mechanisms. In a traditional US IPO, the underwriting syndicate — typically a lead left bookrunner and several co-managers — receives a gross spread averaging 5.5% to 7.0% of gross proceeds (Jay Ritter, University of Florida, 2024 IPO Underwriter Fee Database). This fee pool directly funds the syndicate’s research department through a practice known as “bundled” or “soft-dollar” research support. The lead underwriter’s research analyst is contractually obligated to initiate coverage within 25 to 40 calendar days of listing under FINRA Rule 2241, which governs research analyst independence but does not prohibit initiation tied to underwriting revenue.

In a SPAC merger, the sponsor — a special purpose acquisition company’s founding entity — typically receives a 20% promote (founder shares) in the combined entity, with no underwriting fee for the merger itself. The PIPE investors (private investment in public equity) and the SPAC’s IPO underwriters receive separate fees, but these are structurally smaller and not linked to post-merger research coverage. A 2025 analysis by the NYSE’s Market Quality team found that SPAC sponsors allocate an average of $0.8 million to post-merger investor relations and research support, versus $4.2 million for comparable traditional IPO issuers.

Regulatory Constraints on SPAC Research Initiation

FINRA Rule 2241 imposes specific restrictions on research coverage for SPACs that do not apply to traditional IPOs. The rule’s “quiet period” provisions for IPOs (25 days after listing) are well-defined. However, for de-SPAC transactions, the quiet period calculation is more ambiguous. The SEC’s 2024 Staff Accounting Bulletin No. 121 clarified that a de-SPAC transaction is treated as a “reverse merger” for research initiation purposes, meaning the quiet period begins at the shareholder vote date, not the listing date. This creates a window of 45 to 60 days where analysts cannot publish initiation reports, compared to 25 days for IPOs.

Data from Bloomberg’s sell-side research database confirms the impact: de-SPAC companies in Q1 2025 saw a 38% reduction in research reports published in the first 90 days post-listing compared to IPOs, with the gap narrowing to 22% by day 180 but never fully closing.

Empirical Evidence from 2023-2025 US Listings

Coverage Volume by Sector and Market Cap

The coverage gap is most pronounced in the technology and healthcare sectors, which account for 62% of all SPAC mergers in the 2023-2025 period (SPAC Research, 2025). For issuers with market capitalisations between $500 million and $2 billion at listing — the sweet spot for Hong Kong-based cross-border deals — traditional IPOs received a mean of 7.3 research initiations in the first 12 months, while de-SPAC companies received 3.8. This represents a 48% reduction.

Sector-specific data shows even wider gaps:

Healthcare/Biotech: IPOs: 9.1 initiations; de-SPACs: 4.0 initiations (56% gap)
Technology/Software: IPOs: 8.4 initiations; de-SPACs: 4.5 initiations (46% gap)
Financial Services: IPOs: 6.2 initiations; de-SPACs: 3.1 initiations (50% gap)

The data is sourced from the NYSE’s 2025 Post-Listing Research Coverage Report, which tracked 847 US listings (312 IPOs, 535 de-SPACs) from January 2023 through March 2025.

Quality Metrics Beyond Volume

Coverage volume alone understates the disparity. Analyst report quality — measured by the number of financial model updates per report, the inclusion of discounted cash flow (DCF) analysis, and the frequency of earnings model revisions — also diverges. A 2024 study by the CFA Institute’s US Research Committee found that sell-side reports on de-SPAC companies contained 22% fewer financial metrics on average than IPO coverage reports, with a 31% lower probability of including a full three-statement model.

This quality gap has direct market consequences. Companies with fewer than five sell-side analysts at 12 months post-listing experienced a 14% higher bid-ask spread (measured in basis points) and a 19% lower institutional ownership ratio compared to those with five or more analysts, according to data from the SEC’s Market Information Data Analytics System (MIDAS) for 2024.

The Hong Kong Cross-Border Dimension

Implications for PRC and Hong Kong Issuers

For companies incorporated in the Cayman Islands or BVI with operations in the PRC — the typical structure for Hong Kong-based issuers listing in the US — the coverage gap carries specific risks. The US-China Economic and Security Review Commission’s 2024 annual report noted that PRC-headquartered de-SPAC companies received an average of 2.3 analyst initiations in the first 12 months, compared to 5.1 for PRC companies that completed traditional US IPOs in the same period.

This reduced coverage creates a “visibility penalty” for these issuers. Institutional investors surveyed by the HKEX in its 2024 Market Structure Report (HKEX, 2024) ranked “sell-side research coverage” as the third most important factor in their investment decision for US-listed PRC companies, behind only “financial reporting quality” and “corporate governance standards.” The survey covered 147 institutional investors managing a combined $4.2 trillion in assets.

The Sponsor’s Role in Mitigating the Gap

Hong Kong-based sponsors and financial advisors structuring US SPAC mergers have begun incorporating research coverage commitments into the merger agreement. A review of 47 de-SPAC transactions involving PRC issuers from 2023 to 2025 found that 22% included a contractual commitment from the SPAC sponsor to retain at least one sell-side research firm for 12 months post-merger. These transactions saw a 34% higher analyst coverage count than those without such commitments.

The SFC’s 2023 consultation on SPAC regulation in Hong Kong (SFC, 2023) explicitly referenced the US coverage gap as a risk factor for Hong Kong investors, noting that “the absence of mandatory post-listing research coverage in the US SPAC framework may impair price discovery for retail investors.” The SFC’s subsequent SPAC Listing Rules (effective January 2024) required Hong Kong-listed SPACs to disclose their post-merger research coverage plan in the listing document, a requirement with no US equivalent.

Practical Implications for Issuers and Investors

Issuer Strategy: Pre-Listing Research Commitments

Issuers choosing the SPAC route should negotiate research coverage commitments as a material term of the business combination agreement. The data shows that a contractual commitment from the SPAC sponsor to fund at least three sell-side research firms for a minimum of 12 months post-merger increases the probability of achieving coverage levels comparable to a traditional IPO by 41 percentage points (from 22% to 63%), based on the 2023-2025 NYSE dataset.

Investor Due Diligence: Adjusting Valuation Models

Institutional investors should apply a coverage-adjusted discount to de-SPAC companies when building valuation models. Analysis by the CFA Institute (2024) suggests that a one-standard-deviation reduction in analyst coverage (approximately 3.5 analysts) corresponds to a 12% to 18% increase in the cost of equity capital for mid-cap issuers. For PRC-headquartered de-SPAC companies, this discount should be applied at the upper end of the range.

Regulatory Arbitrage: The Hong Kong Alternative

For issuers with a genuine Hong Kong connection — defined by the SFC as having principal operations in Hong Kong or the PRC — the Hong Kong Stock Exchange’s SPAC regime (effective January 2024) may offer a superior research coverage environment. The HKEX’s Listing Rules require SPAC sponsors to disclose post-merger research arrangements and impose a 12-month lock-up on sponsor shares that aligns sponsor incentives with post-listing performance. Early data from the first five Hong Kong SPAC mergers (completed through June 2025) shows an average of 6.2 analyst initiations in the first 12 months, exceeding the US de-SPAC average of 4.2.

Actionable Takeaways

Issuers pursuing a US SPAC listing should negotiate a contractual research coverage commitment from the SPAC sponsor as a non-negotiable term of the business combination agreement, targeting at least three sell-side firms for 12 months.
Institutional investors should apply a 12-18% coverage-adjusted discount to the cost of equity for de-SPAC companies with fewer than five analyst initiations in the first post-listing year.
PRC-headquartered issuers should expect a 55% reduction in analyst coverage compared to traditional IPOs and factor this into their listing route decision.
Hong Kong-based sponsors structuring US SPAC deals should incorporate research funding provisions into the merger agreement, as the 2023-2025 data shows this increases coverage probability by 41 percentage points.
The HKEX’s SPAC regime, with its mandatory research disclosure requirements, offers a materially superior post-listing coverage environment for issuers eligible to list in Hong Kong.
