So what

Confluent completed its initial public offering in June, and the lockup period on selling stock for company employees ended on Aug. 9. Despite potential selling pressures created by the lockup expiration, encouraging second-quarter results and guidance helped power the stock to big gains last month.

Confluent provides expanded capabilities and cross-platform functionality built on the Apache Kafka open source technology used for data sorting and analytics. Selling what essentially amounts to a more advanced, more versatile version of base software that's available for free might sound like a tall order, but the company's Q2 results suggest that its services are seeing strong uptake in the enterprise sector. 

Sales were up 64% year over year in the second quarter, and revenue for the company's cloud segment tripled to come in at $20 million. The company ended the June quarter with 617 customers with annual recurring revenue contract values of $100,000 or more, an increase of 51% year over year. 

Now what

Confluent stock has continued to make gains early in September's trading. The company's share price is up roughly 5.5% in the month so far.

For the third quarter, the company expects sales to come in between $89 million and $91 million. Management expects the business' adjusted loss per share to come in between $0.23 and $0.24 in the period. 

For the full year, Confluent is guiding for its adjusted loss per share to be between $1.05 and $1.07 on sales between $347 million and $351 million. Confluent has a market capitalization of roughly $15.4 billion and is valued at roughly 44 times the company's midpoint sales target for the current fiscal year.
