McPhy Energy, specialized in low-carbon H₂ production and distribution equipment (electrolyzers and refueling stations), announces that it has been formally notified by Siemens Energy of the exercise of a contractual clause allowing the suspension of the execution of its order for the 16-MW electrolyzer under construction as part of the CEOG project (Western Guiana Power Plant). This suspension is beyond McPhy's control and is not linked to the execution of the contract by McPhy.

The completion of the project to date has already provided an important learning curve for the scaling up of McPhy's tool and industrial experience. The company is ready to take over the execution of the project as soon as its client, Siemens Energy, expresses its intention.

As a reminder, the CEOG project includes the production of H₂ thanks to a high-power electrolyzer, Augmented McLyzer 16 MW, supplied by McPhy, linked to a solar photovoltaic park, coupled with a H₂ storage unit and high-power fuel cells to reduce the carbon footprint related to the supply of electricity to 10,000 households in French Guiana.

Pending further information from Siemens Energy on the follow-up of this project, McPhy must assume at this stage a negative impact on its first half revenue of €2 MM. In this context, McPhy estimates that its revenue for the first half of the year will be between €6 MM and €8 MM. McPhy specifies that it has recorded approximately 60% of the CEOG project revenue as of December 31, 2022, which is not affected by the suspension.
