Crimmins had been serving as interim financial chief, executive vice president of finance and chief accounting officer. Crimmins has been with the company since 2011. Marc Katz had been chief financial officer until early September when he stepped down.
"Given John's financial acumen, expertise, and tenure with Burlington Stores, he is the natural choice to serve as CFO," said CEO Michael O'Sullivan in a press release. "John is an exceptionally talented and well-respected leader and we are confident he will continue to play a key role as we drive growth and profitability at Burlington Stores."
Crimmins said, "I look forward to continuing to work alongside Burlington's board and management team to build on the company's progress. With Burlington's strong financial foundation and talented management team, I am confident in the company's prospects for continued growth and value creation."
Burlington shares have returned 674% since October 2013, far outpacing the S&P 500's gain of 71%, when it returned to the public market after having been owned by private-equity firm Bain Capital.
