Check out the companies making headlines before the bell:
Biogen — Biogen shares are tumbling after the drugmaker and Japanese partner Eisai discontinued late-stage trials of an Alzheimer's treatment. That came after an independent data monitoring committee said the treatment was unlikely to meet its primary goal.
Conagra — The food producer beat estimates by 2 cents a share, with adjusted quarterly profit of 51 cents per share. Revenue was slightly below Street forecasts, however, and the company lowered its full-year organic sale outlook.
Darden Restaurants — The parent of Olive Garden, Longhorn Steakhouse, and other restaurant chains reported quarterly profit of $1.80 per share, 5 cents a share above estimates. Revenue and same-restaurant sales also beat forecasts, and Darden also increased its full-year outlook.
Lands' End — The apparel retailer reported adjusted quarterly profit of 50 cents per share, above the 41 cents a share consensus estimate. Revenue also beat Wall Street forecasts. Comparable-store sales rose 9.1 percent, compared to a Refinitiv consensus estimate of a 2.0 percent increase.
Boeing — Boeing remains under pressure in the aftermath of the most recent 737 MAX crash, with NBC News confirming that the FBI has joined the investigation into the certification process for the jet.

Levi Strauss — Levi Strauss will begin trading Thursday after the jeans maker's initial public offering priced at $17 per share, above the expected range of $14 to $16. That gives the company a market value of $6.6 billion.
Micron Technology — Micron reported adjusted quarterly profit of $1.71 per share, 4 cents a share above estimates. The chipmaker's revenue also topped Street forecasts. Micron's revenue forecast for the current quarter was below estimates, however, and the company is also trimming its capital expenditures as well as idling some production lines amid what it calls a challenging market environment.
Williams-Sonoma — Williams-Sonoma earned an adjusted $2.10 per share for its latest quarter, beating the consensus estimate of $1.96 a share.

The company announced a 5 cents a share dividend hike to 48 cents per share, and increased its stock buyback program by $500 million.
