Executive Summary
- Q1 2025 delivered strong top-line and profitability progress: revenue $47.29M (+24.9% y/y), gross margin 79.7% (+80 bps y/y), and positive adjusted EBITDA $0.47M, with net loss improving to $6.54M (-40% y/y) .
- Wall Street estimates were exceeded: revenue beat consensus (~$45.13M*) and EPS beat (-$0.22* vs actual -$0.15), continuing the beat from Q4 and reversing a slight revenue miss in Q3*.
- Guidance raised at the upper end: FY25 revenue to $193.5–$197.5M (prior $193.5–$195.5M), FY25 gross margin lifted to 78% (prior 77–78%), OpEx growth ~10% (prior ~9%), with positive adjusted EBITDA expected for the full year .

What Went Well and What Went Wrong
What Went Well
- Broad-based growth with strong U.S. execution: U.S. revenue $44.8M (+26.6% y/y), driven by robust procedure demand and new product rollouts (INTRA, Granite 9.5, TNT) .
- Margin expansion and operating leverage: gross margin 79.7% (+80 bps y/y) on mix/ASP and supply chain efficiencies; revenue growth ~3x OpEx growth (7.8%) enabled positive adjusted EBITDA in a seasonally heavier cash-use quarter .
- Physician engagement inflecting: record >1,400 active U.S. physicians and +300 adds in the quarter (+27.3% y/y), with increasing cross-modality usage and territory productivity reaching ~$2M per territory; “Our momentum continues unabated…” – Laura Francis .
What Went Wrong
- International remains modest: international revenue $2.5M vs $2.4M y/y; growth outside U.S. remains small relative to the business mix .
- GAAP loss persists: net loss was $6.54M (EPS -$0.15), though improved materially from prior year; depreciation and growing surgical capacity will weigh on reported margins as the year progresses .
- Seasonality and prudent stance temper guidance cadence: management assumes a 3–5% sequential decline in Q3 on normal seasonality and is maintaining the lower end of FY revenue guidance pending macro clarity .

Earnings Call Themes & Trends
Management Commentary
- “We delivered another quarter of stellar revenue growth, expanded our gross margins and exceeded profitability targets.” — Laura Francis, CEO .
- “Our worldwide revenue was $47.3 million... enabled us to deliver positive adjusted EBITDA.” — Laura Francis .
- “The 80-basis points improvement [in GM] ... better-than-expected ASP [mix of 4-implant Granite cases] and supply chain efficiencies.” — Anshul Maheshwari, CFO .
- “We currently do not anticipate any material impact on gross margins or our supply chain from the proposed tariffs.” — Anshul Maheshwari .
- “We are updating our full year revenue guidance to $193.5–$197.5 million... and expect full year gross margin to be 78%.” — Anshul Maheshwari .
Q&A Highlights
- Growth drivers: Broad-based adoption across SI joint fusion, pelvic fixation, and trauma; Laura emphasized new products from 2024 (INTRA, Granite 9.5, TNT) contributing to accelerating growth, while declining to provide product-level revenue splits .
- Gross margin trajectory: Q1 strength came from ASP/mix and efficiencies; outlook embeds potential ASP moderation and depreciation, with upside possible if 4-implant Granite case mix rises further .
- Cadence and seasonality: Management assumes typical Q3 seasonality (-3% to -5% q/q) and maintained lower-end FY revenue guide to account for macro uncertainty despite strong execution .
- OpEx growth drivers: FY25 OpEx ~10% reflects elevated R&D for two products, higher commissions on revenue growth, and higher G&A vs Q1 run-rate .
- Market development: TAM expansion and physician funnel strategy; interventionalists additively engage SI procedures; record adds and increasing multi-procedure usage support sustained growth .
Estimates Context
- Q1 2025 beat: revenue $47.29M vs ~$45.13M* consensus; EPS -$0.15 vs -$0.218* consensus.
- Q4 2024 beat: revenue $49.00M vs ~$48.87M* consensus; EPS -$0.11 vs -$0.134* consensus.

Key Takeaways for Investors
- Strong execution with successive quarterly profitability progression (AEBITDA positive back-to-back), supported by margin expansion and operating discipline .
- Reimbursement tailwinds (NTAP for TNT; TPT for Granite; CMS DRG proposal) are likely to support ASP/mix and procedure economics, particularly in pelvic fixation and trauma .
- Physician growth and density are key structural drivers; record adds and multi-procedure adoption should sustain double-digit volume growth and support mix/ASP .
- FY25 guidance prudence leaves room for upward revision if macro holds and mix benefits persist; watch Q3 seasonality and depreciation effects on GM .
- Pipeline visibility improves the medium-term thesis: Q1 2026 SI joint solution and third BDD device broaden the portfolio and call points, enhancing growth durability .
- Near-term trading implications: Evidence of consistent beats, raised gross margin guidance, and favorable CMS proposals are positive catalysts; monitor confirmation of NTAP finalization and DRG changes .
- Cash profile improving with lower net cash usage and path to FCF in 2026; leverage likely continues as revenue growth outpaces OpEx .
