Thank you, Santiago. Hello, everyone. Starting with our financial performance on Page 22, I'd like to highlight our revenue growth. We recorded BRL 1.8 billion of gross revenues in the quarter, which is a run rate level of BRL 7.2 billion. Percentage-wise, it means a 40% growth year-on-year or 23% growth on a net of funding cost basis. This dynamic has been led mainly by the ongoing repricing of our portfolio, as mentioned earlier by Alexandre.
On Page 23, we can see that the ARPAC on a cohort basis continues to increase over time with newer cohorts outperforming older cohorts. This reflects our improvements in engagement and cross-sell initiatives, leading to higher monetization.
Jumping to Page 24, we discussed the evolution of our interest margins and CD effect of our repricing strategy moving forward. Starting on the left side, we see our NIM 1.0. It considers all portfolio, including cash receivables that do not accrue interest, also known as [indiscernible] balance in Brazil.
On a quarter-on-quarter basis, our NIM 1.0, improved 20 bps. On the left side, we show our NIM 2.0, which considers only the interest-earning portfolio. In this metric, we saw a 30 bps increase compared to the prior quarter and a 70% -- a 70 bps increase compared to a year ago. It is worth noting that the growth in funding was skewed towards most expensive deposits this quarter. So delivering this NIM increase in such context is a testament of the strong ongoing repricing exercise that we are thoroughly executing.
Flipping to Page 25, in the expense side, we report what we believe is a very strong progress. Our expenses decreased 13% compared to the prior quarter, showing a nominal decrease in most significant lines. In particular, personnel expenses decreased by 17% despite having the impact of the annual increase in the fourth quarter, known as [Foreign Language] in Portuguese. The other lines remained under control, reflecting the strong focus on expense management to deliver the best to our customers in a cost-efficient manner.
Going to Page 26, the improvements can be seen in our operational leverage. The evolution of our ratio of active clients per employee is in a positive trend and has even accelerated further this year. We went from a ratio of 2,600 active clients per employee a year ago to 3,500 active clients per employee in the first quarter. As a result, we have lowered the cost to serve, which now stands at 13.8.
Finally, I would like to highlight the impressive improvement in our efficiency ratio. This is a result of our repricing strategy and cost control initiatives. We reached 62% in this metric, an improvement of 9 percentage points. This is a strong sign of our commitment towards our 5-year business plan presented in the last Investor Day and also as highlighted by Joao.
Moving to Page 27. We recorded a 23% CET1 ratio in the quarter with the lowest level of capital consumption since our IPO. Additionally, if we consider the impact that we expect from the new BACEN rules, taking effect in July of this year, our CET1 ratio on a pro forma basis would increase by an additional 150 bps.
Finally, if we put in context our capital, which is fully comprised of top quality core equity without any hybrid capital instruments. We see that it is, price is higher as the medium of the 5 incumbent banks in Brazil.
On Page 28, I will walk you through our profitability profile. Net income continues trending positively, reaching BRL 24 million. On a pretax basis, we ended the quarter with BRL 6 million income. Our ROE drilling underwriting are efficient funding at scale and our obsession on operational excellence are the foundations to these improvements, which is just getting started.
I'll pass the word back to Joao for his closing remarks.
João Vitor Nazareth Teixeira de Souza: Thank you, Helena. Closing on Page 30, I would like, I would just conclude by saying that, as we mentioned previously, we are harvesting the results of our solid foundations. Across metrics, I see very encouraging improvements on market share, client activation, operational leverage, NIMs and bottom line with the best yet to come.
And last but not least, I would like to thank our amazing team that is motivated, engaged and excited to continue with us on this journey. Many thanks to all for hearing our earnings call.
Operator, we can open it up for questions. Thank you very much.
