Lowe’s Companies Inc. (LOW) is an American home retailing company that provides customers with an extensive range of home improvement products, including home decorating, repair, remodeling, property maintenance, and installation services. Lowe's offers its products and services to both retail and wholesale customers. Lowe's reported fiscal third-quarter earnings on November 20, 2018. The home retailing company reported $17.42 billion in revenues this quarter, reflecting a 3.8% increase from the same period last year.

On Nov. 5, 2018, Lowe's announced that the company will close 51 underperforming stores in North America, with 20 locations in the U.S. and 31 in Canada. Lowe's will close the locations by Feb. 1, 2019, says CEO Marvin R. Ellison, as part of the company's efforts to focus "on its most profitable stores and improve the overall health of its store portfolio." The store closures come as the most recent update from Lowe's Companies, whose CEO of 13 years Robert Niblock retired in March. Lowe's Companies is now headed by Ellison, former CEO of J.C. Penney.

Following news of the store closures, Lowe's announced on Dec. 12, 2018 that the company would buy back $10 billion in company stock. Lowe's shares were down about 1.5% leading up to the company announcement and shot up by nearly 3% in afternoon trading. The company buyback suggests that the company may be confident heading into fiscal year 2019, despite shares having fallen about 5 percent so far this year.

Throughout the company's business and structural changes, Lowe's has remained committed to the belief that a diverse portfolio of products better meets customer needs. Most of Lowe's 106 suppliers are located within the United States, but the company also has suppliers based in South Korea, Canada, China, and Taiwan.
