Full Year and Fourth Quarter 2012 Results

The Company recorded record revenue for the year ended December 31, 2012, with revenue of $27.1 million, more than three times 2011 full year revenue of $7.8 million. Earnings before interest, taxes, depreciation, amortization, impairment of intangibles, earn-out liability and share based compensation (Adjusted EBITDA*) for the year ended December 31, 2012, were $2.4 million, a $8.7 million improvement as compared to the Adjusted EBITDA loss of $6.3 million for the year ended December 31, 2011.

The fourth quarter of 2012 marked the 8th consecutive quarter in which the Company reported improved gross margins. The Company’s 2012 gross margins of 81% are nearly a forty-two percentage point improvement over full year 2011 gross margins of 57%.

The Company recorded record revenue for the quarter ended December 31, 2012, with revenue of $10.5 million, an increase of 299% or $7.9 million over fourth quarter of 2011 revenue of $2.6 million, and a 32% increase over the third quarter of 2012.

Management Commentary on 2012 Results

Parker H. “Pete” Petit, Chairman and CEO, stated, “2012 was an excellent year by all measurements. We increased revenues quarter-over-quarter, produced revenue growth of over three times the previous year, improved our gross profit margins by over 40 percentage points, more than tripled the number of employees in key areas of the Company, and significantly improved the management quality and depth of our organization, particularly in the sales and management functions. Most importantly, we did this while increasing our positive Adjusted EBITDA. The largest portion of our 2012 revenue growth was primarily attributed to our EpiFix^® wound care allograft gaining physician acceptance in numerous Veterans Health Administration (“VA”) Hospitals. We made a strategic decision to add a direct sales force to focus on these government and military accounts since they are not dependent on third party reimbursement for our EpiFix^® tissue grafts. This has proven to be an especially beneficial strategy for the Company that should continue to produce quarter-over-quarter sales growth. Late in the second quarter, we added a national sales director to head up the government sector of our sales force, and we began adding sales executives to that team in early July. The government-focused team today consists of 27 sales executives. Also in the second quarter, we began expanding our direct sales teams focused on the commercial wound care market. That sales team consists today of 15 sales executives. Managing our surgical and sports medicine distributors and sales agents is a group of four sales executives. This group brings our total sales force to 46 people.”
