“Hopper demand remains strong, and the anticipation for Blackwell is incredible,” said CEO Jensen Huang, “Blackwell samples are shipping to our partners and customers.” Earlier this month, The Information reported a potential delay in Blackwell’s delivery due to design flaws.

Nvidia expects the revenue for the current quarter to be $32.5 billion, topping the $31.7 billion estimated by analysts. However, Bernstein analyst Stacy Rasgon said that the buy-side was expecting a higher range of $33 billion to $34 billion, according to CNBC.

Dollar General has lowered its FY24 EPS guidance to a range of $5.5 to $6.2, down from the previous range of $6.8 to $7.55.

“We are not satisfied with our financial results, including top-line results below our expectations for the quarter,” said CEO Todd Vasos. “While we believe the softer sales trends are partially attributable to a core customer who feels financially constrained, we know the importance of controlling what we can control.”

On August 13, Loop Capital lowered Dollar General’s price target to $130 from $140 and kept a hold rating ahead of earnings. The analyst is “increasingly pessimistic” about Dollar General’s short-term prospects, citing growing macroeconomic pressure on the company’s core low-income customers.

The company earned $1.34 per share, up 10% from the expected $1.16. Revenue of $9.29 billion also topped the expected $9.24 billion but represented a 3% decline.
