SALT LAKE CITY, March 5, 2015 (GLOBE NEWSWIRE) — Amedica Corporation (Nasdaq:AMDA), a company that develops and commercializes silicon nitride ceramics as a biomaterial platform, today announced financial results for the fourth quarter and full year ended December 31, 2014.
“This past year has been remarkable for Amedica and I’m pleased to see that momentum carry into 2015,” said Dr. Sonny Bal, chairman and CEO of Amedica Corporation. “We believe the recent clinical, financial, and regulatory developments position Amedica to capture additional market share, enhance our ability to demonstrate the benefits of silicon nitride and promote wider adoption of the material across a number of biomedical platforms. I’m proud of the significant achievements our dedicated team has accomplished to-date, as we seek to leverage the opportunities these achievements provide throughout the balance of this year.”
Total product revenue increased by 2% during 2014 to $22.8 million, as compared to $22.3 million in 2013. This was primarily attributable to a 41% increase, or $3.2 million, in silicon nitride ceramic product revenue over the prior-year period due to increased market adoption of the Valeo™ spinal interbody devices and the Company’s focus on its core silicon nitride technology. 
Gross profit for the full year 2014 totaled $14.9 million, compared to $15.3 million in the same period last year. Gross margin percentage for the full year 2014 was 65%, compared to 68% for the full year 2013. Excluding the impact of excess or obsolete inventory for both years, full year 2014 gross margins improved by 3 percentage points to 77%, as compared to the prior year period, due to production efficiencies and quality improvements.
Net loss for the full year 2014 was $32.6 million, compared to $8.3 million in the prior-year period, primarily as a result of a non-cash stock compensation expense of approximately $10.2 million, higher operating expenses, increased interest expense, a loss on the extinguishment of debt and offering costs incurred during the year.
Adjusted EBITDA, which is defined as earnings before deductions for interest, taxes, depreciation, amortization, non-cash stock compensation expense, change in fair value of our derivative liabilities, offering costs, and loss on extinguishment of debt for the full year 2014 was ($11.9) million, compared to ($7.7) million for the full year 2013.
Cash and cash equivalents totaled $18.2 million, while total principal debt obligations were $24.5 million as of December 31, 2014.
