So what

Arco Platform had its initial public offering last August, and shares are up roughly 37% from its closing price on the day of the company's market debut, thanks to impressive sales momentum. The company has a market capitalization of roughly $1.6 billion and trades at roughly 42 times this year's expected earnings and roughly 13 times expected sales, so while the company is growing very fast, expectations for more strong growth are also already factored into its stock price.

Now what

Because the use of education services tends to correspond with the academic calendar and schools need their systems set up beforehand, much of Arco Platform's business tends to be booked a year in advance. The company's expects bookings of R$440.9 million in 2019, an increase of 37% compared to 2018's academic calendar bookings. Investors can also look forward to the company growing its sales through acquisitions, as management has stated that it is looking for outside assets that can bolster its strength in education services.
