What happened

Shares of radio-frequency company Qorvo (NASDAQ:QRVO) rose as much as 18.8% on Thursday, following the company's third-quarter financial results for fiscal 2018. The stock is up 13.6% at the time of this writing.

Optimism toward Qorvo's stock on Thursday likely reflected its better-than-expected revenue and non-GAAP earnings per share.

Shares initially traded lower after the results because of weaker-than-expected guidance for the company's fourth quarter. But Drexel Hamilton analyst Cody Acree released a note to clients saying expectations for guidance to be weak were already baked into the stock, as shares pulled back about 20% from highs in November. The note may have helped the stock rebound.

So what

Qorvo reported third-quarter revenue and adjusted earnings per share of $845.7 million and $1.69, respectively. These results compared to consensus analyst estimates for revenue of $840.9 million and adjusted earnings per share of $1.60.

Qorvo's non-GAAP gross margin was 48%, up from 47.4% in its second quarter of fiscal 2018.

It's also worth noting that Qorvo's results compared well to its own guidance for the quarter. Management had guided for revenue between $830 million and $850 million, and a gross profit margin of 47.5%.

Now what

Management said it expects fiscal fourth-quarter revenue to be between $645 million and $665 million. Management forecast gross margin to be between flat and up 50 basis points sequentially.

Acknowledging its weaker-than-expected guidance, management is optimistic about longer-term prospects.

"While near-term market demand has weakened in handsets," said Qorvo CEO Bob Bruggeworth, "our longer-term outlook has improved on recent developments with mid/high-band PADs [power-amplifier duplexers], Phase 6 design wins, and cellular IoT [Internet of Things] and other connectivity applications."
