Regulatory filings reveal that Berkshire Hathaway has made a $55 million investment in Macy's. While the scale of this investment is relatively modest, it holds significant meaning. The stake comprises approximately 3 million shares, representing about 1.1% of Macy's total outstanding shares. Notably, this marks Berkshire's first investment in a publicly traded department store company since 1966. In that year, Warren Buffett and his partner Charlie Munger, through a company called Diversified Retail Companies, spent about $6 million to acquire the Baltimore-based department store chain Hochschild Kohn. However, Buffett sold the department store after three years at a price close to the original cost. Munger later candidly stated that the department store business was a "lousy business," as such operations often require continuous capital investment while yielding low profit margins. Given that Macy's is at a critical juncture in its "Bold New Chapter" transformation strategy, the timing of Berkshire's investment is particularly noteworthy. The department store chain has been executing an ambitious turnaround plan, which includes closing approximately 150 underperforming stores by 2028 while concentrating resources on about 350 higher-performing "future-focused" stores. Macy's reached a turning point in the first quarter, achieving its first year-over-year comparable sales growth in several years, with total sales reaching their highest level in over three years. Furthermore, revenue contributions from pilot stores now account for about 75% of the strategic transformation's target revenue. Analysts note this indicates significant progress by Macy's in enhancing the shopping experience and optimizing its merchandise mix. Following the news, Macy's stock price rose nearly 4% during Monday's trading session before paring gains to close up 0.6%. It is reported that Berkshire Hathaway disclosed its first-quarter U.S. stock portfolio on May 15, which represents the first full quarter under Greg Abel's formal leadership following Buffett. Berkshire's investment portfolio showed several notable changes, including a renewed investment in airline stocks after six years and a reduction in long-term holdings such as Bank of America and Chevron. However, Apple, American Express, and Coca-Cola remain its top three holdings.
