received ONA 1; and DF Star, São Luiz Anália Franco and São Luiz Morumbi received their first certification by the Joint Commission International - JCI).

Our investments in service quality, excellent medical staff, technology and safety allowed us to maintain our NPS in line with 2020 results, especially for the assessment of appointment and exam scheduling, showcasing our capacity to grow with high-quality standards. It is also important to note the progress of our digital channels, as a way to attract new customers and obtain loyalty from the current ones. One third of appointments and exams at Rede D'Or are scheduled through these channels. We recorded 200 million visits to the internet portal in 2021, versus 9 million in 2020. On social media, we consolidated our profiles' performance, reaching a high engagement level and strengthening Rede D'Or's role as a benchmark in health and prevention. The results achieved give us a lot to celebrate, and we remain prepared to go further in the pursuit to consolidate our leadership in the industry as well as the social and environmental sustainability of our business. We are one of Brazil's largest employers and our investments are increasing every year. I would like to thank all of Rede D'Or's employees for their relentless dedication to bring excellence to our patients. We have even greater expectations for 2022 and are already excited to come back here to share all the achievements and advancements that are yet to come. Good reading!
