Operating Details

Operating expenses were $162.7 billion, up 15% from the year-ago quarter. As a percentage of revenues, the figure expanded 130 basis points (bps) on a year-over-year basis to 90.3%.

The cost of sales, fulfillment and technology and infrastructure expenses increased 9.5%, 12.2% and 30.2% year over year to $88.6 billion, $27.6 billion and $28.9 billion, respectively.

However, this figure included two substantial special charges, including $2.5 billion related to a legal settlement with the Federal Trade Commission (FTC) and $1.8 billion in estimated severance costs primarily related to planned role eliminations. Excluding these charges, operating income would have reached $21.7 billion, representing strong operational performance. As a percentage of revenues, the figure contracted 150 basis points (bps) on a year-over-year basis to 9.7%.
