And, according to new insights from S&P Global Market Intelligence released last week, there are more to come.

"The convenience of online shopping, and the downward pressure it has put on pricing, has radically altered consumer behavior," S&P analysts wrote. "Most shoppers now browse for value online, and the younger cohort of the prized millennial demographic, some of whom may never have developed a penchant for long afternoons at the mall, clearly prefers that channel."

To determine which companies are most at risk for being next to file bankruptcy, S&P researchers used a statistical model — the Probability of Default (PD) Fundamentals model — that calculates companies’ PDs over a one- to five-year period.

They identified the 10 U.S. retailers with one-year PDs ranging from 6.11 percent (significant risk) to 23.84 percent (highly leveraged credit risk).
