5 terms

comparable sales financial

"Comparable sales for the periods ended May 31, 2026, were as follows:"

"Comparable sales" are the total sales from stores or products that have been open for a certain period, usually the same time last year or last quarter. They help show whether a business is growing by comparing similar locations or products over time, much like checking if your favorite store's sales are going up compared to previous years.

digitally-enabled technical

"Digitally-Enabled | 21.1% | | 21.6%"

"Digitally-enabled" refers to products, services, or systems that use digital technology, like computers or smartphones, to work more efficiently or offer new features. It matters because it allows companies to provide faster, more convenient experiences for customers—like shopping online or managing bank accounts from a phone—changing how we do everyday tasks.

foreign exchange financial

"Comparable sales excluding the impacts from changes in gasoline prices and foreign exchange"

Foreign exchange is the process of swapping one country's money for another’s, like exchanging dollars for euros when traveling. It matters because it determines how much your money is worth in another country, affecting prices, investments, and international trade. This system helps businesses and governments buy and sell across borders smoothly.

forward-looking statements regulatory

"Certain statements contained in this document and the pre-recorded message constitute forward-looking statements"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

U.S. GAAP financial

"are not a substitute for net sales presented in accordance with U.S. GAAP."

U.S. GAAP is a set of rules and standards that companies in the United States follow to prepare their financial reports. It helps ensure that financial information is consistent and clear, so investors and others can compare and understand a company's financial health easily.
