Under Armour picks up the pace

Under Armour's quarterly revenue grew 2.4% to $1.443 billion, while net income jumped over 40% to $75.3 million, or $0.17 per share. On an adjusted (non-GAAP) basis -- which excludes items like stock-based compensation and restructuring expenses -- Under Armour's earnings were $112 million, or $0.25 per share.

Chairman and CEO Kevin Plank claimed the company's performance indicates the its "multi-year transformation is on track," adding:

As we work through this chapter, we are staying sharply focused on our brand by connecting even more deeply with our consumers while delivering industry-leading, innovative products and premium experiences. Coupled with increasingly greater business discipline and resulting efficiencies, we continue to gain confidence in our long-term path and ability to deliver for our consumers, customers and shareholders.

To that end, Under Armour now sees adjusted full-year earnings per share in the range of $0.19 to $0.22, up from its previous guidance for $0.14 to $0.19.

Akama distributes an impressive beat

Akamai stock gained 17% after the content distribution leader handily beat expectations in its third-quarter report. Revenue grew 7% to $670 million, helped by a 37% increase in cloud security solutions (to $169 million). On the bottom line, adjusted net income soared 43% to $157.8 million, or $0.94 per share. Most analysts were modeling earnings of $0.83 per share on revenue of $664 million. 

CEO Dr. Tom Leighton called the results "excellent," noting this marks the company's fourth straight quarter of adjusted operating margin expansion.

"We are well on our way to achieving our 30% margin goal in 2020," Leighton added, "while continuing to invest in innovation and new products to drive future growth."

Akamai's board further approved a new $1.1 billion share repurchase program, adding to the $124 million remaining on its existing authorization. The new program will start next month and remain in effect through the end of 2021.

Chegg passes with flying colors

"We had a great Q3, driven by 37% Chegg Services revenues growth and 45% subscriber growth, year-over-year," stated co-Chairman and CEO Dan Rosensweig. "As we come out of another back to school season, the success we experienced gives us confidence to, once again, raise our guidance for the year, as well as provide a strong initial outlook for 2019."

In particular, Chegg now expects full-year 2018 revenue of $315 million to $318 million, up from its previous range of $306 million to $311 million. For 2019, it's targeting 2019 revenue of $388 million, around $8 million above Wall Street's models.
