London’s Top 2025 Listings Tumble in Blow to IPO Revival Hopes

Why It Matters

The weak debut of London’s marquee listings undermines confidence in the city’s capital‑raising hub, potentially deterring future primary offerings and limiting private‑equity exit options. A sustained downturn could shift IPO activity toward more resilient markets such as the United States or Hong Kong.

Key Takeaways

• Top 2025 IPOs fell average 26% in Q1 2026
• FTSE 250 down 5.4%, FTSE 100 up 2%
• Fermi leads declines, down 40% since year start
• MHA's £360m float rose 25%, only IPO above price
• Geopolitical tension in Iran dampens global IPO enthusiasm

Pulse Analysis

London’s IPO market entered 2026 on shaky footing, as the five biggest 2025 listings collectively shed roughly a quarter of their market capitalisation in the first quarter. The decline starkly contrasts with the FTSE 250’s modest 5.4% dip and the FTSE 100’s 2% gain, underscoring a bifurcated market where blue‑chip resilience fails to lift newer, mid‑size issuers. Companies such as Fermi, a dual‑listed data‑centre energy provider, have seen shares tumble 40%, while Shawbrook Bank slipped a third, reflecting investor scepticism toward growth‑oriented equities in a volatile macro environment.

The slump cannot be viewed in isolation; it mirrors a broader global slowdown in primary listings triggered by heightened geopolitical uncertainty after Iran’s February conflict. Even seasoned financiers like JPMorgan’s Jamie Dimon expressed surprise at private‑equity firms’ reluctance to capitalize on historically strong equity markets, warning that an extended bear market could further erode IPO appetite. The war‑induced risk premium has tightened capital flows, prompting investors to favour established, dividend‑paying stocks over speculative new issues, thereby compressing valuation multiples for fresh floats.

Despite the gloom, market participants remain cautiously optimistic. Peel Hunt’s head of capital markets, Brian Hanratty, cites the strongest IPO pipeline in years, suggesting a potential second‑half revival if geopolitical tensions ease and macro‑economic conditions stabilise. For issuers, timing will be critical: aligning secondary offerings with periods of reduced volatility could restore confidence and attract the institutional demand needed for successful listings. Meanwhile, investors should monitor policy responses and currency dynamics, as a resolved conflict could reignite cross‑border capital flows and re‑establish London as a competitive venue for equity fundraising.
