CHICAGO (Reuters) - German grocery chain Aldi Inc [ALDIEI.UL] said on Sunday it would invest $3.4 billion to expand its U.S. store base to 2,500 by 2022, raising the stakes for rivals caught in a price war. 
  
 Aldi operates 1,600 U.S. stores and earlier this year said it would add another 400 by the end of 2018 and spend $1.6 billion to remodel 1,300 of them. 
  
 The investment, which raises Aldi’s capital expenditure to at least $5 billion so far this year, comes at a time of intense competition and disruption in the industry. 
  
 German rival Lidl will open the first of its 100 U.S. stores on June 15. In May, Lidl said it would price products up to 50 percent lower than rivals. 
  
 Wal-Mart Stores Inc (WMT.N), the largest U.S. grocer, is testing lower prices in 11 U.S. states and pushing vendors to undercut rivals by 15 percent. Wal-Mart, the world’s biggest retailer, is expected to spend about $6 billion to regain its title as the low-price leader, analysts said. 
  
 The furious pace of expansion by Aldi and Lidl is likely to further disrupt the U.S. grocery market, which has seen 18 bankruptcies since 2014. The two chains are also upending established UK grocers like Tesco Plc (TSCO.L) and Wal-Mart’s UK arm, ASDA. 
  
 In May, Aldi Chief Executive Jason Hart told Reuters the chain intended to have prices at least 21 percent lower than rivals and would focus on adding in-house brands to win over price-sensitive customers.

 “We’re growing at a time when other retailers are struggling,” Hart said in a statement. Hart added that Aldi’s prices were also up to 50 percent lower than traditional grocery chains, a move that appeared to follow rival Lidl’s announcement on prices. 
  
 The latest store expansion will create 25,000 U.S. jobs and make Aldi the third-largest grocery chain operator in the country behind Wal-Mart and Kroger Co (KR.N), the German chain said in a statement. Aldi’s 2,500 stores would equal about 53 percent of Wal-Mart’s U.S. outlets. 
  
 “As we continue to expand and grow, our purchasing power continues to increase and allows us to bring products at better prices for consumers,” Scott Patton, Aldi’s head of corporate buying, said in an interview. ||||| In this June 5, 2017, photo, a woman and child walk from Aldi food market, in Salem, N.H.

 NEW YORK (AP) — Low-cost grocery chain Aldi says it plans to add more stores in the U.S. over the next five years, meaning more competition for traditional grocers, Walmart and organics-focused chains like Whole Foods. 
  
 The German company focuses on private-label goods, like Trader Joe's does — so no Kraft macaroni and cheese — and has 1,650 stores in the United States. Aldi says it aims to give customers organic produce and meat raised without antibiotics. 
  
 It was already planning on expanding to 2,000 stores by the end of 2018. The company now says it will be at 2,500 locations by the end of 2022. 
  
 In comparison, Kroger, one of the largest U.S. grocery companies, owns chains including Kroger, Fry's, Ralphs and Harris Teeter and has about 2,800 supermarkets. |||||
A:
You definitely know Walmart, and you likely know Kroger. If you don't know Aldi, that will probably change by 2022. The low-cost grocery chain was already planning on expanding its 1,650 stores to 2,000 by the end of 2018. The company now says it will be at 2,500 locations by the end of 2022 thanks to a $3.4 billion investment. Reuters reports that count will make it the third largest grocery chain in America. Kroger—which also owns Fry's, Ralphs, and Harris Teeter—has about 2,800 supermarkets; Walmart is at about 4,700. The German company focuses on private-label goods, as Trader Joe's does—so no Kraft macaroni and cheese—and says it aims to give customers organic produce and meat raised without antibiotics. How the AP paints the move: more competition for traditional grocers, Walmart, and organics-focused chains like Whole Foods. CEO Jason Hart in May told Reuters its prices were in some cases half of what supermarkets charge. "We're growing at a time when other retailers are struggling."
