Performance Analysis
ATEC’s third quarter results reflect a business scaling efficiently on all fronts. Revenue reached $197 million, with surgical revenue comprising $177 million and EOS, imaging and informatics platform, contributing $20 million. Surgical growth was underpinned by a 28% increase in procedural volume, driven by a 26% rise in net new surgeon users—evidence of both new account wins and deeper wallet share with existing surgeons. Notably, same store sales in established territories grew 30%, signaling that ATEC’s differentiated offering is resonating even in mature markets.
Profitability inflected sharply upward as operating discipline and infrastructure leverage took hold. Non-GAAP gross margin held steady at 70%, while SG&A, selling, general and administrative expense, as a percent of sales dropped to 57% from 67% a year ago, driving 980 basis points of improvement. Operating margin expanded by over 1100 basis points year over year, and adjusted EBITDA hit a record $26 million, representing 13% of sales. Free cash flow turned positive for the third time in four quarters, and the balance sheet remains robust with $156 million in cash and $60 million in undrawn revolver capacity.
- Procedural Volume Outpaces Market: 28% volume growth and 26% net new surgeon users reflect competitive share gains and product pull-through.
- SG&A Leverage Accelerates: Operating expense discipline and sales force efficiency yielded nearly 10 percentage points of margin improvement.
- Cash Flow Turns Structural: Positive free cash flow and asset efficiency signal a transition to self-funded growth.
ATEC’s revenue growth algorithm is proving durable across cycles, with operating leverage and cash generation now compounding as the business scales.
Executive Commentary
"We are creating value through creating clinical distinction which compels surgeon adoption. And we continue to just get better from a field perspective. So we like to say around here that the spine market needs ATEC. And I've never been a bigger believer in that view since I've started. And you got to realize the spine field is highly complex. ... Our view is that the industry needs a focal leader obsessed with mitigating variables in spine, and we are it."
Pat Miles, Chairman and CEO
"Our operating expense investment reflect continued prioritization of strategic growth initiatives supporting sales expansion and new product development. While our foundational infrastructure is in place, we continue to expand the sales force, build out procedural solutions, and integrate technology, data, and information into the operating room experience. ... The evidence of the company's inflection to cash flow generation is undeniable with our trailing 12 months of free cash flow turning positive for the first time in company history."

Strategic Positioning
1. Spine-Only Focus as a Competitive Moat
ATEC’s 100% spine focus is a key differentiator, enabling every operational and R&D decision to reinforce procedural depth and surgeon relevance. This singularity is increasingly rare as larger medtech peers consolidate or diversify, and management repeatedly emphasized that this focus underpins both innovation velocity and market share gains.
2. Proceduralization Drives ASP and Predictability
ATEC’s proceduralization strategy—integrating multiple products into cohesive surgical workflows— is expanding both average selling price (ASP) per case and predictability of outcomes. Lateral, cervical, and now deformity segments are all benefiting from this approach, with new launches like Corpectomy and Identity II broadening addressable pathologies and deepening surgeon loyalty.
3. Technology Integration and Data-Driven Ecosystem
ATEC’s investment in technology platforms—EOS, Valence navigation and robotics, and SafeOp neurophysiology— is creating a data-rich, fully integrated surgical ecosystem. The upcoming Valence launch is positioned to democratize advanced procedures for a broader surgeon base, while EOS Insight’s informatics are already driving both implant and imaging pull-through.
4. Operating Model Built for Scale and Leverage
Prior investments in infrastructure, sales force, and systems are now yielding consistent margin expansion, with SG&A and R&D leveraged against accelerating top-line growth. Management highlighted that current EBITDA levels enable self-funding of future instrument and inventory needs, reducing capital intensity and supporting a path to de-levering.
5. Early-Stage Deformity and International Upside
Deformity and international remain in early innings, with EOS-driven preoperative planning and patient-specific implants just beginning to influence market share. The international footprint, while still small, is tracking to long-term targets, and product innovation in deformity offers a multi-year growth catalyst.
Key Considerations
This quarter’s results reinforce ATEC’s strategic thesis—a spine-only, technology-enabled, proceduralized model that is now compounding operating leverage and cash flow. Investors should weigh the durability of this growth algorithm, the timing and scale of new product ramps, and the competitive dynamics as industry consolidation accelerates.
Key Considerations:
- Surgeon Adoption as a Forward Indicator: 26% net new surgeon users and robust same store sales growth signal ongoing share capture and future revenue durability.
- Technology Platforms as Differentiators: EOS and Valence integration are central to ATEC’s “ecosystem” thesis, driving both procedural adoption and informatics leadership.
- Operating Leverage Now Structural: Margin gains are not one-off; they result from years of foundational investment now yielding scale benefits.
- Guidance Philosophy Remains Conservative: Management continues to guide with a “beat and raise” approach, leaving room for upside as new launches ramp.
- Industry Disruption as Tailwind: Ongoing consolidation among legacy players is viewed as an opportunity to hire talent and win share amid market disruption.
Risks
Key risks include execution on major product launches—particularly Valence and further deformity innovation—alongside the challenge of sustaining high surgeon adoption rates as the base grows. Tariff impacts, while managed, remain a cost headwind, and competitive responses from larger, consolidated spine players could intensify. Management’s conservative guidance approach leaves room for upside but also reflects caution amid industry volatility and macro uncertainties.
Forward Outlook
For Q4 2025, ATEC guided to:
- Free cash flow of $6 million to $8 million
- Continued positive adjusted EBITDA and margin expansion
For full-year 2025, management raised guidance:
- Revenue to $760 million (up $18 million from prior guidance)
- Adjusted EBITDA to $91 million (up $8 million)
