Performance Analysis
ATEC’s Q1 performance demonstrated significant operational and financial momentum, with total revenue reaching $169 million, driven by 24% growth in surgical revenue and 8% growth in EOS, the company’s imaging and informatics platform. Notably, procedural volume rose 17% and average revenue per procedure climbed 6%, reflecting both new surgeon adoption and richer procedural mix. Same-store sales, a measure of mature territory performance, grew 23%, underscoring penetration in established markets.
Margin expansion was a highlight, as non-GAAP operating margin improved by 900 basis points year-over-year, reflecting both top-line growth and a disciplined expense profile. Operating expenses increased just 8% despite double-digit revenue growth, with SG&A as a percentage of sales dropping 400 basis points. Adjusted EBITDA reached $11 million, yielding a 6% margin and marking the twelfth consecutive quarter of margin expansion. Free cash use was at the favorable end of guidance, and refinancing of convertible notes extended maturity while preserving balance sheet flexibility.
- Sales Force Productivity: Continued investments in sales infrastructure and territory buildout are yielding higher productivity and deeper market reach.
- EOS Order Book Surges: A 28% year-over-year increase in EOS orders signals growing demand for end-to-end informatics solutions and future pull-through on implants.
- Cash Burn Reduces Sharply: $15 million cash use represents a $55 million improvement over the prior year, with working capital headwinds viewed as transient.
ATEC is now leveraging its scale and procedural innovation to deliver consistent profit growth, while maintaining a strong liquidity position and executing against long-term goals.
Executive Commentary
"Our thesis is working and where we have representation that's been established, we continue to compel adoption and so. The durable revenue growth drives profitability and cash flow clearly. EOS order growth was also a record for which we're very, very encouraged. It's a foundation of our strategy."
Pat Miles, Chairman and CEO
"This quarter also marks our second consecutive period with an over 40% drop through on a year-over-year revenue growth to adjusted EBITDA, reflecting both infrastructure scalability and an improving variable selling expense profile."
Todd Koenig, CFO
Strategic Positioning
1. Procedural Platform and Surgeon Adoption
ATEC’s differentiated procedural strategy—anchored by platforms like PTP (Prone Transpsoas Procedure), LTP (Lateral Transpsoas Procedure), and the new corpectomy system—continues to drive new surgeon adoption and deeper engagement. The company’s approach bundles implants, customized exposure tools, monitoring, and soon navigation, creating a comprehensive solution that addresses surgical complexity and predictability. This “convoy sales” model, where multiple products are used per procedure, is expanding both revenue per case and account stickiness.
2. EOS Informatics and Market Access
EOS, ATEC’s imaging and informatics platform, is emerging as a key access lever, opening doors to academic institutions and new surgeon groups previously underpenetrated. Record EOS order growth and the launch of ES Insight software are enabling pre-, intra-, and post-op informatics integration, with predictive analytics and alignment planning poised to reduce revision rates and enhance clinical outcomes. The majority of new EOS placements are with previously non-ATEC accounts, broadening the company’s reach in both adult deformity and pediatric markets.
3. Operating Leverage and Cost Discipline
ATEC’s focus on infrastructure scalability and cost management is translating revenue growth into profit at an accelerating rate. SG&A and R&D spend have remained relatively flat as a percentage of sales, and asset utilization—particularly with sets and instrumentation—continues to improve. The Memphis facility investment and operational maturity are yielding tangible gains in working capital efficiency and cash flow.
4. Commercial Execution and Sales Force Dynamics
ATEC’s reputation as the “preferred destination” in spine is attracting high-quality reps from competitors, with new hires delivering incremental volume and expanding the company’s geographic and procedural footprint. The onboarding process, while requiring 12-18 months for full productivity, is delivering on expectations, and increased set efficiency is enabling broader placement and faster ramp.
5. Innovation Pipeline and Robotics
The company’s robotics and navigation roadmap is on track for a year-end launch, with the alpha phase underway and early feedback emphasizing workflow efficiency and seamless integration. Management is focused on ensuring that automation enhances, rather than impedes, surgical throughput—a critical differentiator in the spine robotics landscape.
Key Considerations
ATEC’s Q1 results reinforce its strategic thesis, but investors should weigh the following considerations as the company advances toward its 2027 goals:
Key Considerations:
- Margin Progression: Twelve straight quarters of EBITDA margin expansion signal a sustainable shift in profitability, yet further scale is needed to reach long-term targets.
- EOS Pull-Through Potential: EOS placement in new accounts is driving implant pull-through, but the full revenue impact will materialize over multiple years as procedural adoption deepens.
- Tariff Exposure: Tariffs on French-manufactured EOS units will hit COGS in the second half, though management expects the impact to be low single-digit millions and limited in scope.
- Sales Force Buildout: Continued rep onboarding and training are critical to sustaining high growth, with a lag between hiring and territory maturity.
- International Opportunity: ATEC’s “narrow and deep” approach in Australia, New Zealand, and Japan is showing early traction, but broader international expansion remains measured and capital-light.
Risks
Tariff volatility remains a near-term cost risk, particularly as U.S. trade policy evolves. Competitive dynamics in spine—especially from larger, diversified players—could slow surgeon conversion or pressure pricing. Execution risk around robotics launch and further EOS integration also persists, alongside the challenge of maintaining rapid growth as the business scales. Macroeconomic downturns, while historically less impactful to spine, could still affect hospital capital budgets and procedural volumes.
Forward Outlook
For Q2 2025, ATEC guided to:
- Cash flow in the range of $0 to $5 million
For full-year 2025, management raised guidance:
- Revenue of approximately $734 million (20% growth)
- Surgical revenue of $658 million (21% growth)
- EOS revenue of $76 million
- Adjusted EBITDA of $78 million (11% margin)
Management highlighted several factors that underpin their outlook:
- Mid-teen surgical volume growth and mid-single digit revenue per surgery growth
- Continued leverage of infrastructure and operating expense discipline
Takeaways
ATEC’s Q1 marks a pivotal step in its transformation, with margin inflection and operating discipline now matching the company’s innovation-led growth narrative.
- Profitability Leverage: Revenue growth is translating into outsized EBITDA gains, with cost discipline and infrastructure scale driving sustainable margin expansion.
- Procedural and Informatics Distinction: EOS and procedural platforms are opening new account doors and deepening surgeon engagement, validating ATEC’s differentiated model.
