CARLSBAD, Calif., November 9, 2017 -- Alphatec Holdings, Inc.

Third Quarter 2017 Financial Highlights

Organizational, Commercial, and Product Highlights

“I am pleased with the execution of our team during the third quarter. Our financial results were in-line with our pre-announced ranges. In spite of the revenue challenges presented by weather and the sequential loss of two selling days in the quarter, we successfully managed operating expenses and improved cash burn,” Said Terry Rich, CEO, “We also drove momentum in the transition of our sales channel and made excellent progress on the initiatives that remain priorities as we reimagine Alphatec, keeping us on track to grow revenue sequentially in the fourth quarter.”   

“I am especially excited to welcome Pat Miles, one of the spine industry’s most respected leaders, to our team,” added Rich. “Under his leadership, and with his passionate contribution to Alphatec’s product development, marketing, and surgeon engagement, we will lead the industry in terms of spine experience, driving innovation that improves the surgical experience and patient outcomes.  We are exceptionally well-positioned to take market share in the U.S. spine segment.”  

Comparison of Financial Results for the Third Quarter 2017 to Second Quarter 2017

Following is a table, comparing key third quarter 2017 results to second quarter 2017 results.  At this time, the Company believes that sequential results are the best indicators of performance. These are the comparisons management uses in its own evaluation of continuing operating performance given the re-focus of the Company’s strategy under a new leadership team.

U.S. commercial revenue for the third quarter of 2017 was $20.7 million, down $1.2 million compared to $21.9 million in the second quarter of 2017.  The sequential decline was driven primarily by the impact of two less surgery days in the third quarter, weather-related impacts, and deliberate decisions to discontinue non-strategic relationships.

U.S. gross profit and gross margin for the third quarter of 2017 were $14.3 million and 69.1%, respectively, compared to $15.5 million and 70.9%, respectively, for the second quarter of 2017. The decrease in gross margin was due to lower sales volume, changes in product mix, and the impact of variations in inventory write-offs as the Company continues to optimize its supply chain.

Total operating expenses for the third quarter of 2017 were $15.8 million, reflecting a decrease of $0.7 million compared to $16.5 million in the second quarter of 2017.  On a non-GAAP basis, excluding restructuring charges and a gain on sale of assets, total operating expenses in the third quarter improved by $1.2 million compared to the second quarter of 2017. The improvements reflected the execution of operational improvement initiatives, including workforce reductions, facilities consolidation, and the success of ongoing efforts to reduce expenses.

GAAP loss from continuing operations for the third quarter of 2017 was $3.1 million, compared to a loss of $2.6 million for the second quarter of 2017.

Non-GAAP Adjusted EBITDA in the third quarter of 2017 was $1.1 million, compared to $1.2 million in the second quarter of 2017.  For more detailed information, please refer to the table, "Alphatec Holdings, Inc. Reconciliation of Non-GAAP Financial Measures", that follows.

Current and long-term debt includes $33.0 million in term debt and $9.2 million outstanding under the Company’s revolving credit facility at September 30, 2017. This compares to $33.6 million in term debt and $8.9 million outstanding under the Company’s revolving credit facility at June 30, 2017.

Cash and cash equivalents were $15.4 million at September 30, 2017, compared to $19.1 million reported at June 30, 2017.  In October 2017, the Company secured a commitment for additional equity investments of $3.5 million to $4.0 million, payable on or before January 1, 2018, and generated cash proceeds of $1.7 million from the exercise of warrants.

Comparison of Financial Results for the Three and Nine Months Ended September 30, 2017 and 2016

Revenue decreased on a year-over-year basis as a result of the Company’s execution of its sales organization transition and the impact of lost revenue related to the financial and operational challenges the Company faced in 2016 prior to the sale of its international business.  The year-over-year improvement in operating expenses is the result of a comprehensive initiative to reduce costs and drive operational efficiencies.  For additional information, please reference the following financial statement tables and the Company’s Quarterly Report on Form 10-Q to be filed with the Securities and Exchange Commission on November 10, 2017.

Non-GAAP Information

To supplement the Company’s financial statements presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company reports certain non-GAAP financial measures such as Adjusted EBITDA.  Adjusted EBITDA included in this press release is a non-GAAP financial measure that represents net income (loss), excluding the effects of interest, taxes, depreciation, amortization, stock-based compensation expenses, and other non-recurring income or expense items, such as sale of assets, impairments, restructuring expenses, severance expenses and transaction-related expenses.  The Company believes that non-GAAP Adjusted EBITDA provides investors with an additional tool for evaluating the Company's core performance, which management uses in its own evaluation of continuing operating performance, and a baseline for assessing the future earnings potential of the Company.  For completeness, management uses non-GAAP Adjusted EBITDA in conjunction with GAAP earnings and earnings per common share measures. The Company’s Adjusted EBITDA measure may not provide information that is directly comparable to that provided by other companies in the Company’s industry, as other companies in the industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. Adjusted EBITDA should be considered in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Included below are reconciliations of the non-GAAP financial measures to the comparable GAAP financial measure.
