Alphatec Holdings, Inc. (NASDAQ:ATEC), a provider of innovative solutions dedicated to revolutionizing the approach to spine surgery, today announced financial results for the quarter ended September 30, 2021, and recent corporate highlights.

Third Quarter 2021 Financial Results

Recent Highlights

• Advanced the adoption of the Prone Trans-Psoas (PTP) Technique, with ATEC lateral delivering over 50% of Q3 revenue growth;
• Expanded surgeon users by 20% compared to Q3 2020;
• Generated over $11 million in EOS-related revenue and continued to build demand with a 25% increase in the pipeline of interest since the transaction closed;
• Enhanced the versatility of the InVictus Posterior Fixation Platform with the release of Osseoscrew, the only expandable screw commercially available in the U.S.;
• Released the ALIF Standalone Interbody System, which improves intra-operative optionality and restores alignment at L4/L5 and L5/S1 where the majority of alignment is derived;
• Closed a convertible debt offering, reducing debt service and raising net proceeds of $188M for continued investment in growth.

"In the third quarter, ATEC continued to earn market share by delivering on our promise to create procedures that improve patient care," said Pat Miles, Chairman and Chief Executive Officer. "Despite ongoing market impacts, our surgeon customer base increased significantly. The accelerating uptake of PTP is testament to the reflected know-how and ATEC's ability to design technology for specific approach requirements. This is expanding adoption of the lateral approach by surgeons who have historically relied on posterior techniques. We are also making progress integrating EOS imaging, and are confident that system placements are laying the foundation for an improved clinical experience that will set the standard for surgical planning, intra-operative information and predictive analytics. I am incredibly bullish that ATEC's organic innovation machine will continue to drive long-term, multi-faceted growth. Despite our many successes to date, we know we are still only getting started."

Financial Outlook for the Full Year 2021

The Company now expects total revenue for the fiscal year ended December 31, 2021, to approximate $235 million, reflecting growth of approximately 62% compared to the prior full year. This includes an organic revenue contribution of approximately $208 million, or 47% growth compared to the prior full year, which has been updated to reflect the impact of the COVID pandemic in the third quarter 2021. The Company now anticipates about $26 million of revenue related to EOS imaging, which accounts for slightly stronger than expected EOS-related revenue in the third quarter 2021. Total revenue guidance for the full year also includes an approximate $1 million contribution from the Company's international supply agreement, which terminated on August 31, 2021.

Non-GAAP Financial 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, including non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating loss, and non-GAAP adjusted EBITDA. The Company believes that these non-GAAP financial measures provide 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. The Company's non-GAAP financial measures 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. Non-GAAP financial results 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 measures.
