Paris, January 6, 2026. Diapason, pioneer in Treasury Value Management and provider of the myDiapason platform, announces the completion of its acquisition of DeftHedge, a SaaS solution specialized in FX Risk Management, Forex Automation, and commodity hedging.

Following consultation with employee representative as required, the transaction has been finalized according to the announced timeline. The DeftHedge team has joined Diapason, strengthening Diapason’s position as the go-to partner for finance departments in Treasury Management and Financial Risk control.

• Monitor and control FX, interest rate, and commodity exposures in real time
• Neutralize financial risks while capturing favorable market movements
• Ensure data accuracy and standardize financial reporting
• Accelerate hedge strategy implementation
• Optimize hedging costs through advanced analytics tools

The two complementary SaaS platforms now provide corporations with tailored solutions to their treasury management and financial risk challenges.

With this acquisition, Diapason now offers a comprehensive Treasury Value Management solution covering the full range of corporate treasury needs:

• Financial Risk Management: FX and Commodity exposure management with Forex automation (DeftHedge and myDiapason Risk)
• Liquidity Management: Financial resource optimization and advanced forecasting, beyond traditional cash management (myDiapason Liquidity)
• Payment Security: Centralized payment flows and protection (myDiapason Payment)
• Guarantees: Strategic tracking of off-balance-sheet commitments (myDiapason Guarantees)
• Investments: Portfolio and equity holdings management (myDiapason Invest)

This comprehensive approach enables Diapason to support companies across their entire financial value chain, from day-to-day treasury operations to sophisticated market risk hedging.

“This acquisition is fully aligned with our Treasury Value Management strategy,” says Raphaël de Talhouët, CEO of Diapason. “Our mission is to help finance departments transform their treasury function into a genuine value creation lever. By strengthening our FX risk management and Forex automation capabilities through DeftHedge, we can deliver an even more comprehensive and powerful solution to our clients.

“Joining Diapason is excellent news for our clients and our team,” adds Olivier Lechevalier, CEO of DeftHedge. “We share the same vision: financial risk management should be a performance driver, not a constraint.
