(Corrects to show sales were weaker, not weaker than expected in first paragraph; and in headline, that sales fall)
May 21 (Reuters) - Best Buy Co Inc reported weaker quarterly sales on Tuesday and warned that a slew of investments to win back shoppers could squeeze profits in the near term.
The news overshadowed a better-than-expected profit from the world's largest consumer electronics chain in the first quarter and sent its shares down 4 percent in premarket trading.
Net earnings from continuing operations fell to $97 million, or 29 cents a share, from $169 million, or 49 cents a share a year earlier. Excluding restructuring and other charges but including Europe, it earned 36 cents a share, beating the analysts average estimate of 25 cents a share, according to Thomson Reuters I/B/E/S.
