Shell on Friday reported a 28% drop in first-quarter net profit to $5.58 billion, beating analyst expectations, and kept the pace of its share buyback programme steady amid falling oil prices and lower refining margins than last year.

Amazon exceeded Wall Street’s revenue and profit expectations for the first quarter — but delivered a new warning about the potential future impact of tariff and trade policies on its future financial guidance.

Amazon guided for $159 billion to $164 billion in Q2 sales and $13 billion and $17.5 billion in Q2 operating income, compared to estimates of $161.2 billion in sales and $17.6 billion operating profit for Amazon’s current quarter.
