Jeff Bezos may have vacated the CEO chair, but Amazon.com Inc. keeps humming along.

Amazon today released its first quarterly earnings report since Andy Jassy succeeded Bezos as CEO July 5, and it shows Amazon increased its net income by 48.4% in the second quarter compared with the same period last year, while total revenue rose 27.2%.

North American revenue increased 21.9% and international sales by 35.5%. North American sales had grown year over year by at least 39% over the previous four quarters, driven by the surge in online shopping during the COVID-19 pandemic. With brick-and-mortar stores opening up—particularly in the U.S.—this spring, online shopping growth has tapered.

However, Amazon juiced its Q2 revenue by moving its annual Prime Day sale, which is normally in July, into June, putting that revenue in the second quarter. (The 2020 sale took place in October because of the pandemic.) Consumers worldwide spent $11.19 billion on Amazon sites during the two-day Prime Day event in June, up 7.6% from $10.39 billion during the October 2020 sale, according to Digital Commerce 360.

North American operating income increased 47.0% compared with the second quarter last year. Amazon’s profits, while strong during the pandemic, were impacted in the second quarter of 2020 by Amazon’s heavy spending to protect workers and customers during the pandemic. The company reported with its Q2 release last year that it had incurred $4 billion in such expenses from March to June 2020.

As usual, a big part of Amazon’s profits came from its industry-leading cloud computing unit, Amazon Web Services. AWS increased its revenue by 37.0% and its operating income by 24.9% in the second quarter. While AWS accounted for only 13.1% of Amazon’s Q2 sales, it contributed 54.4% of operating income, down from 57.5% in the same quarter last year.

Also contributing to the profit surge was an increase of nearly $3.7 billion, or 87.5%, in what Amazon calls its “Other” category, which is mainly revenue from ads retailers and brands purchase to promote their goods to Amazon shoppers on the company’s websites. Facebook Inc. and Google parent Alphabet Inc. also reported big increases in online advertising this week as companies increased their ad spend this spring in response to a surge in post-pandemic online shopping.

Amazon’s Q2 net income of $7.8 billion was just shy of its record profit of $8.1 billion in the first quarter of 2021.
