The group is made up of three operating companies: Pax Lubrificantes Ltda., Elvin Lubrificantes Industria e Comercio Ltda. and Lubripack Industria e Comercio Ltda., which manufacture and sell greases and lubricating oils for automotive and industrial use, as well as a plastic blow molding unit.

On February 8, 2025, a fire incident occurred at the Industrial Complex (“CIG”) of the subsidiary CLE, located in Rio de Janeiro, Brazil.

The fire affected part of the production area and administrative offices, that were not operational on the day, representing 10% of the total complex area.

All emergency and risks protocols during the crisis have been put into practice immediately to control the incident and all containment measures through the execution of the Company’s contingency plan worked satisfactorily to minimize more serious damages, including our structure, local community and environmental. There were no victims or injured people in the incident and no material environmental or social impacts were identified.

The bulk operations for lubricants and base oils, tanks terminal, marine operations, pier operations, which represent around one third of production, did not have their operations affected and continue to operate regularly.

The Company has already started its continuity plan to reestablish the blending & filling operations.

Due to effective containment and safety measures, the fire was controlled and just the finished lubricants products manufacturing was impacted and is closed at the moment for inspections and assessments, thus maintaining the operation of the entire rest of the industrial complex – bulk operations for lubricants and base oils, tanks terminal, marine operations, pier operations – which is currently estimated to represent 30% to 35% of production.

As part of Company´s continuity and response plan for a crisis of this nature, there are essentially four counter measures, which are already in implementation: i) Reallocate blending & filling to Company´s affiliates; ii) Product availability and supply chain directly through our strategic alliance; iii) Production by third-party partners approved by the Company; iv) Safety Inventory Level spread across its distribution centers network.

Due to the complexity of Moove's operating segment, all global operations have comprehensive insurance coverage, with policies covering operational risks, business interruption damage, civil liability and environmental liability. The company has started evaluating and carrying out inspections with insurance companies. The indemnity limit totals approximately R$1,200,000 for this incident in the affected region.

As a result of the event, Moove will record, in 2025, the write-off of the affected assets at the CIG lubricants plant, which are part of its South American cash-generating unit, impacting the balance sheet and income statement. The amount of the write-off/loss is being analyzed, with a current estimate of between R$190,413 and R$285,620 for inventory and fixed asset losses. Business interruption losses are not quantifiable at this time.

The company has hired a specialized company, which has mastery and knowledge of our operation, in order to carry out a physical inventory of the assets in the CIG that were damaged and of the entire perimeter that was not affected. The aim is to ascertain the real extent of the loss with greater precision, accurately identify the assets affected and catalog them, and measure the losses due to devaluation (cost value - accumulated depreciation), as provided for in IAS 36 - Impairment of Assets. In addition, the specialized company will issue a loss assessment report to support the appropriate accounting records. At the time of issuing these financial statements, the appraisal work had not been completed.

The Company reassessed the assumptions of its long-term financial modeling, considering the incident and reviewing scenarios with multiple variants, including stress tests. The main assumption tested was the volume of sales in liters, with a variation in the Compound Annual Growth Rate (“CAGR”) from 2.4% to 1.6% over 5 years. After this review and considering the information available, it is highly probable that there will be no need to recognize provisions for impairment on December 31, 2024. The Company maintains its operations on a going concern basis.
