Check out the companies making headlines after the bell on Tuesday:
Shares of La-Z-Boy plummeted 15 percent in extended trading after the company reported a same-store sales decline.
In the fiscal first quarter, La-Z-Boy saw same-store sales drop by 1.9 percent. During the comparable period last year, the company had comparable-sales growth of 5.3 percent.
La-Z-Boy also posted earnings that missed analysts' expectations on Tuesday. The company reported adjusted earnings of 28 cents a share on revenues of $341 million, below Wall Street projections of 29 cents a share on $359 million in revenue, according to Thomson Reuters.
Shares of Tesla whipsawed in extended trading, last edging higher by 0.10 percent following Tesla CEO Elon Musk's announcement of a new Model S and X.
The company claims its Model S P100D with Ludicrous mode is the fastest production car in the world, in terms of acceleration. Tesla compared it to the likes of the LaFerrari and the Porsche 918 Spyder, which were faster, but were limited-run cars, while the Tesla will be factory-produced for the general public.
Shares of Intuit slid 3 percent in extended trading after the company reported a very weak first-quarter guidance.
The financial management solutions company reported first-quarter revenue guidance between $740 million and $760 million. Analysts expected $772.7 million for the first quarter of fiscal 2017, according to a Thomson Reuters estimate.
Intuit also reported an earnings and revenue beat for its fiscal fourth-quarter with earnings of 8 cents per share on revenue of $754 million. Analysts expected a loss of 2 cents per share on revenues of $744 million.
Shares of Nimble Storage popped 2.2 percent in extended trading following the company's second quarter results that beat expectations.
Nimble Storage reported a second quarter loss of 19 cents per share ex-items on revenue of $97.1 million. Analysts expected a loss of 20 cents per share on revenue of $95 million.
Shares of Best Buy edged lower by 0.25 percent in extended trading after the company beat second quarter earnings and revenue estimates earlier in the day.
Best Buy reported second-quarter earnings of 57 cents per share ex-items on revenue of $8.53 billion, compared to analysts' projections for earnings of 43 cents per share on revenues of $8.39 billion, according to a Thomson Reuters consensus estimate.
