1. Iran decision: President Donald Trump will announce his decision on whether to scrap the Iran nuclear deal at 2:00 p.m. ET.

Trump is widely expected to stop waiving sanctions on Iran's energy and banking sector that were lifted as part of the 2015 agreement in exchange for curbs on Tehran's nuclear program. US allies have urged Trump to stick with the deal.

Trump's decision could have a major impact on energy markets. Oil prices have surged nearly 13% over the past month to their highest level since 2014 on fears of supply disruptions.

"[The] decision on whether to pull out of the deal to limit sanctions on Iran in return for limits to its nuclear program will hang over markets," said Kit Juckes, a strategist at Societe Generale.

2. Disney earnings: Disney (DIS) will report its quarterly earnings after the closing bell.

The company is likely to boast about the success of "Black Panther," which has made more than $688 million domestically. Its "Avengers: Infinity War" and the upcoming Star Wars movie "Solo" are also expected to be huge hits.

Investors will be looking for updates on Disney's plan to buy most of 21st Century Fox (FOX), which is scheduled to report on Wednesday.

Shares in Fox surged nearly 5% in extended trading after Reuters reported that Comcast (CMCSA) is speaking to investment banks about obtaining financing to potentially crash the Disney-Fox deal.

3. Pharma deal: Japan's Takeda (TKPHF) said it has finalized a deal to buy Dublin-based biotech firm Shire (SHPG) for £46 billion ($64.3 billion).

Shire's board had said that previous takeover bids from Shire had undervalued the company and put its future growth at risk.

Shares in Takeda gained 4% in Tokyo, while Shire stock was up 3.6% in London.

4. Global market overview: US stock futures were flat.

European markets opened mixed, following a mostly positive trading session in Asia.

The Dow Jones industrial average and the S&P 500 both gained 0.4% on Monday. The Nasdaq added 0.8%.
