What happened with Align this quarter

Everything seemed to go right for Align in the second quarter. The biggest driver of its revenue growth, though, was international sales of its Invisalign clear aligners. Align's international Invisalign revenue soared to $83.7 million in the second quarter from $61.9 million in the prior-year period -- a 35.2% increase.

The company also recorded North American clear aligner revenue of $143.9 million in the second quarter, up 14% from the $126.1 million posted in the same quarter of 2015.

Align's scanner and services revenue nearly tripled year over year, increasing to $26 million from $8.7 million in the prior-year period. This impressive growth stemmed from high demand for the company's iTero Element scanner.

The company reported$685 millionin cash, cash equivalents, and marketable securities on hand at the end of the second quarter. Align still has no debt on its balance sheet.

What management had to say

Joe Hogan, Align's president and CEO,highlighted the great numbers from his company's second-quarter results:

Looking forward

Align expressed a positive outlook for the third quarter. The company projected Invisalign case shipments will be between174,200 and 176,900, up18.1%-19.9% from the third quarter of 2015. Net revenue for the third quarter is expected to be between$267.2 millionand$273.5 million, with diluted earnings per share of $0.49-$0.52.

Two factors in the details of Align's quarterly results bode well for the company's prospects. First, the number of doctors to which Align shipped Invisalign cases jumped nearly 13% year over year. The biggest growth came from international markets. Second, the utilization rate by doctors for the second quarter was 5.1%, a significant increase from the 4.6% rate reported a year ago.

Continued success for iTero Element also indicates that Align is competing well against a bigger rival, Dentsply Sirona (NASDAQ: XRAY). The merger earlier this year of Dentsply, a leader in the dental consumables market, and Sirona, which makes dental technology and equipment, might have made some Align investors a little nervous, because Dentsply Sirona's Cerec scanners compete against Align's iTero scanners. So far, though, it appears the market is big enough for both companies to succeed.

Even though it's smaller than Dentsply Sirona, Align is in better shape in terms of its cash position. What will the company do with its sizable cash stockpile? Over the last couple of years, Align has spent $250 million repurchasing its shares. It plans to keep the repurchase program going by buying back another $50 million in stock soon. Align also recently authorized another $300 million buyback.

Not every quarter will be as positive as Align's second quarter. However, if the company keeps its momentum going with Invisalign and scanner sales, it should give long-term investors confidence in Align's future.
