The annual tariff adjustment process consists of passing on to consumers the uncontrollable costs of the concession (Part A - energy purchase, sector charges, and transmission charges) and updating the controllable costs (Part B - distribution) by the variation of the IGPM minus the X Factor, which transfers to consumers the annual productivity gains of the concessionaire.

The variation in Part A costs was +2.56%, totaling R$ 4,721.6 million, due to the new

transport tariffs. The average price of energy purchase contracts ("PMix") was set at R$ 272.74/MWh.

The variation in Part B was -6.8%, totaling R$ 2,804.06 million, reflecting the accumulated inflation (IGPM) since the last adjustment, of -4.26% deducted from the X Factor of 2.55%.
