Inthe opinion of the Company's Management Board, the immediate disclosureof the inside information could violate the Company's legitimateinterests, because the immediate public disclosure of the above insideinformation regarding the purpose of the Credit Agreement and the LoanAgreement could negatively affect the asset purchase negotiationprocess, particularly creating a significant risk of a possibledeterioration of the Company's negotiating position vis--vis InfraredAssociates Inc.. Furthermore, the immediate public disclosure of theinside information could lead to an improper assessment of thisinformation by the public, considering the then-current stage of theasset purchase negotiation process, the lack of a concluded assetacquisition agreement, and the lack of binding decisions regarding someelements of the asset acquisition agreement. Additionally, the partieshad not yet finalized the agreed terms of the potential transaction inthe asset purchase agreement, and there was a need to conduct aninternal coordination process and obtain the required corporateapprovals within the Company.

Thepublic disclosure of the above information before the occurrence of theindicated events could have led to market circumstances or third-partybehavior which, in the Company's assessment, would potentiallyjeopardize the ongoing negotiations and the outcome of the Process.Specifically, the public disclosure of the subject information couldhave misled the public as to the possible outcome of the process.

TheCompany's Management Board simultaneously assures that it has taken thesteps required by the MAR Regulation to maintain the confidentiality ofthe delayed inside information until its public disclosure, inparticular by applying internal procedures for information circulationand protection.
