Executive Summary

Q4 2023 revenue was $47.27M, up 18% YoY; gross margin improved to 74% from 73% YoY, with net loss of $13.0M and EPS of -$0.33. Management guided FY 2024 revenue to $194–$198M, citing deepening TCAR adoption and policy tailwinds from CMS expanded coverage .
The quarter delivered a revenue/EPS beat versus third-party consensus: Zacks reported EPS consensus at -$0.40 (actual -$0.33, a 17.5% beat) and revenue beat of 11.93% (actual $47.27M), implying a strong demand backdrop and operating leverage tailwind .
Strategic highlights: expanded CMS coverage for TCAR, limited market release of tapered ENROUTE Transcarotid Stent configurations, and new distribution agreements in Japan and China following product clearances—positioning for broader access and international channel development .
Management noted a temporary favorable stent cost-of-goods purchase price variance boosting Q4 gross margin, expected to persist through Q1 and normalize in Q2; modest full-year gross margin improvement anticipated versus 2023 .
Stock reaction catalysts: demonstrated beat on EPS and revenue against consensus, improved margins, CMS coverage expansion, and FY24 guide above FY23 actuals—all potential positive drivers as estimates adjust to the higher growth trajectory .

What Went Well and What Went Wrong

What Went Well

TCAR adoption deepened; 2023 procedures exceeded 25,000 with cumulative >85,000, supporting 28% FY revenue growth to $177.1M and Q4 revenue of $47.27M (+18% YoY) .
Gross margin improved sequentially to 74% in Q4 (vs. 73% Q3 and 71% Q2), aided by higher production volumes and a temporary favorable stent COGS variance; management anticipates modest full-year margin improvement .
CEO tone was confident on policy and evidence tailwinds: “With the right team in place, broad reimbursement, and extensive evidence in support of TCAR, we are laser focused on deepening adoption…” (Chas McKhann, CEO) .

What Went Wrong

OpEx rose 18% YoY in Q4 to $49.17M, driven by headcount and commercial expansion; net loss remained elevated at $13.01M (EPS -$0.33) despite margin gains .
Management flagged normalization of stent cost benefits after Q1 and called out typical Q1 seasonality (mid-single-digit sequential revenue decline), implying near-term EBITDA pressure before improving through the year .
Q2/Q3 margin pressures reflected dual manufacturing facilities and prior period cost revaluation impacts, underscoring sensitivity to production variances and cost structure while scaling .

Management Commentary

CEO strategic message: “With the right team in place, broad reimbursement, and extensive evidence in support of TCAR, we are laser focused on deepening adoption in physicians who perform TCAR” (Chas McKhann) .
CFO commentary on margin/near-term cadence: Q4 gross margin benefited from larger production volumes and a temporary favorable stent purchase price variance; expect this to continue through Q1 before normalizing in Q2, with modest full-year gross margin improvement versus 2023 .
Liquidity/profitability outlook: Ended 2023 with $190.9M in cash and investments; management expressed confidence in achieving profitability with existing capital, while flagging a larger adjusted EBITDA loss in Q1 given seasonal revenue patterns .

Q&A Highlights

Seasonality and Q1 setup: Management expects a mid-single-digit sequential revenue decline in Q1 versus Q4, consistent with historical seasonality; this implies a larger adjusted EBITDA loss in Q1 before improvement later in the year .
Gross margin sustainability: Temporary stent COGS tailwind to persist through Q1, normalize in Q2; overall modest margin expansion expected for 2024 as volumes and efficiency improve .
Adoption drivers: Focus on deepening TCAR usage among trained physicians; CMS expanded coverage expected to reduce administrative barriers and support broader access .
International ramp: New distribution partners in Japan and China after product clearances; early steps to broaden global reach and diversify revenue channels .
Capital and profitability: Confidence in path to profitability with current cash/investment balance and modest burn profile .

Estimates Context

S&P Global consensus data was unavailable via our tool for SILK in Q4 2023 (mapping issue). As a third-party proxy, Zacks reported EPS consensus at -$0.40, with actual EPS -$0.33 (17.5% beat), and revenue beat of 11.93% on actual $47.27M—suggesting a material top- and bottom-line beat versus expectations .
Given the FY24 revenue guide of $194–$198M versus FY23 actual $177.1M, estimates are likely to adjust upward for 2024 revenues and modestly for margins, while Q1 expectations should reflect seasonality and normalization of temporary COGS benefits .

Key Takeaways for Investors

Q4 print showed robust demand and operating leverage: revenue +18% YoY; gross margin 74% with strong beats vs third-party consensus—supportive for estimate revisions and sentiment into FY24 guidance range [$194–$198M] .
Watch near-term cadence: management flagged Q1 seasonality and temporary COGS tailwind normalization, implying a softer Q1 margin/EBITDA profile before improvement resumes .
Policy tailwinds: CMS expanded coverage reduces administrative barriers and broadens access—likely to sustain adoption momentum in TCAR over 2024+ .
Portfolio and channel expansion: Limited release of tapered ENROUTE stent configurations and new Japan/China distribution agreements add product differentiation and international optionality .
Cost discipline will be key: OpEx rose 18% YoY in Q4; investors should monitor hiring pace, commercial spend efficacy, and manufacturing efficiency as volumes scale .
Liquidity supports execution: $190.9M cash/investments and modest burn profile underpin management’s confidence in achieving profitability without incremental capital .
Trading implications: Near-term strength may hinge on continued revenue beats and gross margin resilience; medium-term thesis rests on TCAR category penetration, policy support, international ramp, and operating leverage as temporary COGS benefits fade .
