Martha Stewart Living Omnimedia Reports Fourth Quarter and Full Year 2013 Results

NEW YORK, Feb. 25, 2014 /PRNewswire/ — Martha Stewart Living Omnimedia, Inc. (NYSE: MSO) today announced its results for the fourth quarter and full year ended December 31, 2013. The Company reported net income for the fourth quarter of $7.0 million and net loss of $(1.8) million.

“We ended the full year with a $54.5 million improvement in Operating Income from the prior year. In the fourth quarter just completed, growth in Merchandising was offset by anticipated lower revenues from Publishing which was expected due to the restructuring that took place in the prior year to reduce our print title count from four to two,” said Dan Dienst, Chief Executive Officer. “As promised, we also took some aggressive and important steps in the last quarter of 2013 to align our cost structure with marketplace realities and more importantly to become nimbler, more efficient, generators of ideas, inspirations, content and product. We also promised to put to bed several pieces of notable and distracting litigation, and we did so.” Mr. Dienst continued, “With some of the best, brightest and most passionate employees in our business lines – all of whom have embraced our new way of chasing opportunities as One Company—we are very excited about the groundwork we will lay in 2014 for tapping our esteemed brand’s fullest potential.”

Fourth Quarter 2013 Summary

Total revenues were $47.4 million in the fourth quarter of 2013, compared to $56.4 million in the fourth quarter of 2012 as the 2012 publishing restructuring resulted in lower revenues partially offset by growth in Merchandising.

Merchandising

Revenues increased 12% to $18.2 million for the fourth quarter of 2013, as compared to $16.2 million in the prior year’s fourth quarter, benefitting from royalty revenue recognition, new in 2013, from the Company’s relationship with J.C. Penney.

Corporate

Corporate expenses were $(6.3) million in the fourth quarter of 2013 compared to $(10.6) million in the prior year’s quarter, due to a reimbursement from our insurance carrier related to the Macy’s litigation and lower executive compensation.
