In this sense, it is possible to infer that the market as a whole presented a growth of 10% in volume over the average of the last 3 months. Additionally, when analyzing the transactions with the Santander Brasil’s securities, as well as the transactions with the securities of other issuers in the same segment, it can be seen that the average of the volumes recorded in the period from 01/12/2022 to 01/25/2022 is in line with the averages of business volumes carried out in the last 90, 180 and 360 days.

The Company has not yet identified any movement outside the normal course of its business that represented or could result in an out of ordinary variation in its volume of transactions. On this occasion, it is important to highlight that the Company has been in its restricted period to negotiate with its managers and employees since January 3rd, due to the fact that it is in the 30 days prior to the publication of the results for 4Q21 and for the fiscal year ended on 31 December 2021, which is why, among the positions indicated in the tables above, there is no movement on the part of its controllers and managers.

The Company concludes, based on the information it has at the present date, that the domestic market is going through a period of growth and that Santander Brasil has been capturing part of this growth based on its usual course of business.

In view of the above-mentioned Official Letter, we renew on this occasion our highest assurances of distinguished esteem and sincere consideration, and we remain at your disposal to resolve any doubts and additional requests.
