Here’s what to expect in the week ahead.

Signatures due for ballot measures to limit fracking.

Monday is the deadline for environmental activists in Colorado to submit the signatures required to put two proposals on the state’s ballot in November. Both would restrict hydraulic fracturing in oil and gas fields. Hydraulic fracturing, better known as fracking, allows oil companies to fracture shale and other hard rocks with water, chemicals and sand to free oil and gas. Environmentalists contend that the practice can pollute air and local water supplies, but the companies insist it is safe. The more aggressive of the two initiatives would amend the Colorado Constitution to within 2,500 feet of occupied buildings, water resources and public spaces like parks. Clifford Krauss

Valeant Pharmaceuticals will report its quarterly earnings on Tuesday, providing new clues about how and whether the company can climb out of its current morass. One focus will be on how Joseph C.

There is also speculation that Valeant will for 2016, having done so twice already. Mr. Papa was in late April, replacing J. Michael Pearson, who had built Valeant through serial acquisitions and aggressive price increases on old drugs. But the once high-flying company fell to earth starting last fall as about those price increases, the high debt from all those acquisitions and Valeant’s once-secret relationship with a mail-order pharmacy. Valeant faces various federal investigations and its stock has fallen more than 90 percent from its peak a year ago. Andrew Pollack

Iger, Disney’s chief executive, acknowledged that fewer people were subscribing to ESPN as part of a traditional cable package, about the future of television. Disney’s stock has since fallen 20 percent. So, when Mr. Iger again takes the mike on Tuesday to discuss its fiscal third-quarter results, all eyes will be on ESPN. Insight into Disney’s latest thoughts about piping its television networks to consumers over the internet is hoped for.

Wall Street will also be paying attention to Disney’s theme parks. How is the new doing? How strong is Disney World in Florida, where an led to negative headlines? Are safety fears (especially after the nightclub shooting in Orlando) taking any toll? Brooks Barnes
