By October of that year, he'd found it: a $9.4 billion plan to buy Rite Aid Corp. that would have vaulted Walgreens past CVS Health Corp. to become by far the largest U.S. drugstore chain.

在当年的10月份，他发现了一项价值94亿美元，收购医药连锁店来德爱公司（Rite Aid Corp.）的计划，该计划将使沃尔格林超越西维斯健康集团（CVS Health Corp.），成为迄今为止美国最大的药品连锁店。

Pessina, who owns 15.9 percent of Walgreens shares, lost $1.2 billion of his personal wealth in one day; the stock's total decline since his Britain-centered Alliance Boots drugstore chain merged with the U.S.- based chain has reached 28 percent.

佩斯纳拥有沃尔格林15.9%的股份，他一天内损失了12亿美元的个人财富；自从他将以英国为中心的博姿联合药品连锁店与美国连锁店合并以来，这只股票的总跌幅已达28%。
