In this context and as part of the Bank's capital planning, it is reported that in the extraordinary meeting held today, the Bank's Board of Directors agreed to propose the Ordinary Shareholders' Meeting to be held in the first quarter of next year, the distribution of an amount not exceeding 30% of the profits corresponding to year 2021.

The Board of Directors also agreed that this shareholders' meeting will be held remotely, so that the technological means that will be used will constitute the sole and exclusive mechanism to participate and vote, in order to prevent any exposure to contagion, in accordance with the recommendations and mandatory measures of the Chilean authorities. The information regarding how to register, connect and participate remotely in this meeting, will be available and will be communicated timely in the notices of summons to the meeting and on the Bank's website www.itau.cl.
