NextFin News - The speculative fervor that once defined the U.S. "space SPAC" boom has crossed the Atlantic, finding a new and more concentrated home in the London and Frankfurt markets. Seraphim Space Investment Trust, the world’s first listed space-tech fund, has seen its share price quadruple over the past twelve months, hitting a peak of 250.50p this May after languishing near 58p a year ago. The rally signals a shift in investor appetite toward European aerospace suppliers that have successfully integrated into the global supply chains of giants like SpaceX and the U.S. Department of Defense.
The surge is not limited to diversified funds. Filtronic, a British manufacturer of high-frequency communications equipment, has seen its stock climb 130% since the start of 2026. The company’s momentum accelerated following a strategic partnership with SpaceX and a recent £0.4 million contract with a major European defense prime for wide-bandwidth solutions. In Germany, OHB SE has similarly benefited from the "orbital tailwind," as European governments ramp up sovereign satellite capabilities to reduce reliance on foreign infrastructure. This localized craze suggests that while the initial U.S. space bubble was driven by pre-revenue startups, the European iteration is focusing on established "picks and shovels" providers.
James Bruegger, Chief Investment Officer at Seraphim Space, has been a vocal proponent of the sector's long-term viability, consistently arguing that the "New Space" economy is reaching a commercial inflection point. Bruegger, who has managed the trust since its 2021 IPO, maintains a structurally bullish stance, viewing the current rally as a market correction toward the true value of satellite data and orbital logistics. However, his optimism is not universally shared. Some analysts at London-based boutiques have noted that Seraphim’s valuation remains highly sensitive to interest rate expectations, given the long-duration nature of its underlying venture capital holdings. The fund’s recent performance, while spectacular, still reflects a recovery from a period where it traded at a deep discount to its net asset value.
The current enthusiasm faces significant headwinds that could derail the "space-tech" narrative. Unlike the software-as-a-service (SaaS) boom, space remains a capital-intensive industry with binary risks; a single launch failure or a canceled government contract can wipe out years of projected earnings. Furthermore, the European market lacks the depth of the U.S. private capital ecosystem, making these firms more dependent on public market sentiment. If U.S. President Trump’s administration shifts its procurement strategy toward domestic-only suppliers, European firms like Filtronic could see their primary growth engine—U.S. commercial contracts—stutter.
From a historical perspective, the 314% annual return of Seraphim Space is more reminiscent of the 2020-2021 tech mania than a stable industrial recovery. While the fundamental demand for low-earth orbit (LEO) connectivity is undeniable, the pace of share price appreciation has outstripped revenue growth for many of these mid-cap players. Investors are currently pricing in a "goldilocks" scenario where defense spending remains elevated and commercial satellite constellations continue to expand without technical or regulatory delays. Any deviation from this path, particularly a tightening of credit conditions, would likely expose the fragility of these high-multiple valuations.
