Aurora Diagnostics has canceled its long-delayed plans for an IPO. The Palm Beach Gardens-based diagnostics services company filed IPO documents with the U.S. Securities and Exchange Commission in April 2010, seeking to raise up to $150 million. Although it never set a date or price for that offering, the company updated its financial results every quarter to keep its eligibility for the offering current. It even held several conference calls for prospective investors. Aurora Diagnostics raised $200 million in December 2010 through a private bond placement.
