About this report
While sovereign guarantees and innovation grants reshape the macro landscape, a critical bottleneck remains on the factory floor: liquidity. On 17 September 2025, the European Investment Fund (EIF) fundamentally altered the financing equation for defence supply chains by anchoring the Sienna Hephaistos private credit fund with €30 million.
This move signals the rise of a new asset class: non-dilutive private debt specifically structured for dual-use SMEs that are "too strategic to fail" but often too complex for traditional banks. With bank lending still lagging, private credit funds are stepping in to finance working capital, inventory, and M&A for the mid-market.

- How does non-dilutive private debt work as a financing mechanism for dual-use SMEs 'too strategic to fail' but too complex for traditional banks?
- Which working-capital, inventory and M&A needs of the defence mid-market does this instrument finance in 2025-2026?
- What are the risks and limits of private credit filling the gap left by lagging bank lending?
