The meal kit industry is a tale of two brands these days. On one side is Blue Apron Holdings, Inc. (NYSE: APRN), a busted IPO that has lost nearly 80% of its share value since its market debut last June. On the other is HelloFresh, the German company that is quickly taking market share from Blue Apron and has seen its stock move steadily higher since its IPO on the Frankfurt Stock Exchange in November.While Blue Apron is losing customers and sales, HelloFresh just posted a blowout earnings report with revenue jumping 69% in its fourth quarter on a constant-currency basis.
