DRONE VOLT, a manufacturer of professional civilian drones and an expert in onboard solutions, announces the signing of a cooperation and investment agreement with Sol.One (Sol1 BV), a Belgian company partnering in the development of the Saboteur UAV drone system.

This strategic partnership includes the following key elements:

• A firm order of at least 50 million euros spread over the next five years;
• The marketing of the Saboteur UAV system in France to designated customers;
• Cross-investment and cross-ownership between the two companies.

The purpose of this agreement is to jointly develop Sol.One's Saboteur UAV drone system (civilian and military versions).

As part of this agreement, Sol.One also commits to ordering propulsion systems and components from DRONE VOLT for a minimum of 10 million euros per year for five consecutive years, representing a cumulative firm commitment of at least 50 million euros. DRONE VOLT thereby becomes the exclusive supplier of these components for the Saboteur UAV.

Sol.One also grants DRONE VOLT the exclusive right to market the Saboteur UAV systems to designated customers in France as an independent reseller.

As part of this agreement, Sol.One will acquire a stake in DRONE VOLT valued at 2.5 million euros, based on the latest stock prices prior to the transaction. Additionally, DRONE VOLT will participate in a 2.5 million euro capital increase by Sol.One in the coming weeks.

Marc COURCELLE, CEO of DRONE VOLT, stated: “We are very pleased to sign this historic agreement with Sol.One, which will enable us to contribute to the development of the cutting-edge Saboteur UAV system and to become a key supplier of its components through the firm order of at least 50 million euros over five years included in the partnership. This agreement once again demonstrates the excellence of DRONE VOLT's expertise, developed over many years, and we would like to thank Sol.One for their trust.”
