What happened with Amazon this quarter?

Three months ago, Amazon guided its second-quarter revenue toward roughly $61.5 billion. The actual top-line result exceeded that guidance projection by 3%.

Further down Amazon's income statement, management had aimed its operating income at approximately $3.1 billion. Here, the company delivered a $3.01 billion result -- 3% below the midpoint of a roomy guidance range.

The e-commerce giant also reported $9.12 billion of operating cash flows and $2.64 billion in capital expenses for the second quarter, which works out to $6.48 billion of free cash flows. That's a 103% year-over-year increase. Amazon's stated long-term goal is to "optimize free cash flows," giving this metric a seat of paramount importance.

North American retail sales rose 20% above the year-ago period's, landing at $38.7 billion. International sales of $16.4 billion delivered a 12% year-over-year boost. Meanwhile, the Amazon Web Services segment (AWS) posted 37% sales growth, stopping at $8.38 billion.

Beyond the dry figures

The Amazon Prime free shipping program upgraded the age-old promise of two-day delivery to next-day shipping across the entire system, including in the just-added United Arab Emirates market.

"Free one-day delivery is now available to Prime members on more than ten million items, and we're just getting started," said CEO Jeff Bezos in a prepared statement. "We've received a lot of positive feedback and seen accelerating sales growth."

On that note, the Amazon Prime Day event in early July were the two busiest days of Prime sign-ups in the program's history. Management did not provide an updated tally of Prime members, which was last reported as "more than 100 million" in the spring of 2018.

Looking ahead

Based on general business trends and on the record-setting Prime day event, Amazon provided the usual set of next-quarter guidance ranges.

At the midpoint of each range, Amazon expects to see third-quarter revenue near $68 billion while operating profits should stop in the neighborhood of $2.6 billion. These targets compare to $56.4 billion in top-line revenue and $3.7 billion of operating income in the same period of fiscal year 2018.
