Revenue and comparable-store sales also exceeded Wall Street forecasts and Best Buy raised its full-year comparable sales forecast.

Snowflake (SNOW) – Snowflake lost 11 cents per share for the first quarter, smaller than the 16 cents a share loss that analysts were anticipating. The cloud computing company’s revenue also topped forecasts, but shares fell 3.3% in the premarket as losses grow at a similar rate as its sales.

Despite the beat, Dollar General shares fell 1.5% in premarket trading.

Medtronic (MDT) – The medical device maker beat estimates by 8 cents a share, with quarterly earnings of $1.50 per share. Revenue beat estimates as well, as medical procedures rebounded amid a receding pandemic. Medtronic also raised its dividend by 9%.

Dollar Tree (DLTR) – The discount retailer’s shares fell 2.7% in the premarket after it issued a lower-than-expected earnings outlook for the full year. Dollar Tree beat estimates on the top and bottom lines for its latest quarter, and comparable-store sales rose more than expected.

American Eagle (AEO) – American Eagle beat estimates by 2 cents a share, with quarterly profit of 48 cents per share. Revenue was slightly above Wall Street projections. The apparel retailer benefited from increased spending by customers who received stimulus checks, boosting demand and cutting the need for markdowns.

Nvidia (NVDA) – Nvidia reported quarterly profit of $3.66 per share, compared to a consensus estimate of $3.28 a share. Revenue exceeded Street forecasts, with the chip maker also issuing an upbeat revenue outlook.
