AeroVironment, a company that provides unmanned aircraft systems and tactical missile systems for defense, government, and commercial customers, saw its stock jump in after-hours trading, having risen about 10% as of 6 p.m. EST. The stock's gain followed the company's fiscal 2019 third-quarter results, which boasted better-than-expected earnings per share and strong guidance.

Revenue for the period rose 38% year over year to $75.3 million, putting the company's top line slightly above the consensus analyst estimate for the key metric. Earnings per share for the period, however, crushed analysts' estimates. EPS was $0.35, up from $0.02 in the year-ago quarter and beating analysts' average forecast for $0.14.

Management also notably raised its outlook for full-year fiscal earnings per share. The company now expects fiscal 2019 EPS between $1.60 and $1.80, up from a previous forecast for EPS between $1.30 and $1.50. 

The company's profitability benefited from a higher gross profit margin. AeroVironment's gross margin rose seven percentage points year over year, from 33% to 40%. A higher gross profit margin, the company said, was a function of higher sales, demonstrating the scalability of AeroVironment's business.

Though Ambarella's overall business is still in decline, investors betting on the company's turnaround plans may have been given a glimmer of hope on Tuesday.

Shares of semiconductor company Ambarella shot about 6% higher as of 6 p.m. EST in after-hours trading. The stock's gain followed the company's fourth-quarter results, which featured higher-than-anticipated non-GAAP earnings per share.

Fourth-quarter revenue fell 28% year over year to $51.1 million, while non-GAAP earnings per share declined from $0.47 in the year-ago quarter to $0.14. Revenue barely beat analysts' average forecast for $50.9 million, and non-GAAP earnings per share was 10 cents higher than the consensus estimate.

"Strategically, fiscal 2019 was one of the most important years in Ambarella's 15-year history as the company continued to execute on its transformation from a pure video processing company to a computer vision company," said Ambarella CEO Fermi Wang in the company's earnings release.

For its first quarter of fiscal 2020, management expects revenue to be about $47 million, plus or minus 3%. In addition, the company guided for a non-GAAP gross margin between 59% and 60%.
