Business News Reading Comprehension

Read the following excerpts from recent business news articles and answer the questions that follow.

Excerpt 1

Shares of Costco fell slightly on Thursday, despite the warehouse club posting quarterly earnings and revenue that topped estimates and reporting 8% year-over-year sales gains.

Costco's net income for the three-month period that ended May 11 rose to $1.90 billion, or $4.28 per share, compared with $1.68 billion, or $3.78 a year earlier. Revenue rose from $58.52 billion in the year-ago period.

Comparable sales, an industry metric that takes out one-time factors such as store openings and closures, rose 8%, and e-commerce sales rose nearly 16% compared with the year-ago period, excluding gas and the impact of changes to foreign exchange.

About a third of Costco's U.S. sales are goods brought in from other countries, CFO Gary Millerchip said on the company's earnings call. He said items imported from China represent about 8% of total US sales.

Excerpt 2

Lowe's on Wednesday stood by its full-year forecast, as growing sales among home professionals helped offset slower demand from do-it-yourself customers.

The home improvement retailer came in just shy of Wall Street's expectations for quarterly sales, but beat earnings estimates.

In the company's news release, CEO Marvin Ellison said investments in its stores, technology and customer service have helped the retailer get through "near-term uncertainty and housing market headwinds."

Home improvement demand has been in a sluggish stretch as high interest rates and slower housing turnover hurt U.S. consumers' appetite to spend on pricier projects. With its outlook, Lowe's predicted it will snap out of the sales slump this year, but only with slight year-over-year gains.

In the three-month period that ended May 2, Lowe's net income fell to $1.64 billion, or $2.92 per share, compared with $1.76 billion, or $3.06 per share, in the year-ago quarter. Revenue fell from $21.36 billion.

Comparable sales decreased 1.7% year over year. Unfavorable weather hurt sales demand, but sales on Lowe's website and among home professionals grew, Ellison said on the company's earnings call.

Sales to home professionals grew by mid single-digits in the quarter, he said. Ellison attributed those gains to investments Lowe's has made in the business since 2018, including expanding its merchandise lineup and launching a pro loyalty program.

4. The Lowe's article mentions that sales to home professionals helped "offset slower demand" from DIY customers. What does "offset" mean in this context?

9. Why is it important for a financial news report to mention a metric like comparable sales instead of just total revenue?

10. If you were an investor, which company's report would give you more confidence for short-term growth? Explain your reasoning in one or two sentences, using evidence from the text.
