Butterfly Network (BFLY) Q4 2025 earnings review
Strategic Pivot Pays Off With Record Revenue and Positive Cash Flow
Butterfly Network reported a blowout Q4, with revenue accelerating 41% year-over-year to a record $31.5 million. The quarter validated management's strategic pivot toward semiconductor licensing: a new co-development partnership with Midjourney contributed $6.8 million, proving the 'Butterfly Embedded' thesis. Crucially, the company generated its first-ever positive operating cash flow ($6.3 million) and slashed its Adjusted EBITDA loss to $3.2 million. However, stripping out the Midjourney revenue reveals a more modest ~10% core growth, and international sales actually contracted. FY26 guidance suggests the momentum will continue, projecting 20-24% annual growth.
🐂 Bull Case
The $6.8M Q4 revenue injection from Midjourney proves Butterfly's 'Ultrasound-on-Chip' technology has massive licensing value outside traditional medical device sales. This single deal represents up to $74M over five years.
Achieving $6.3M in positive operating cash flow in Q4 removes near-term survival risks. With $150.5M in the bank, the company has ample runway to fund its path to sustained profitability.
🐻 Bear Case
International sales decreased 6% YoY, and core product revenue without the Midjourney licensing deal showed only incremental growth, suggesting the core medical hardware market remains tough to penetrate.
Total operating expenses rose 22% YoY to $37.9 million. While management cites investments in sales and client experience, rising costs could threaten the trajectory to GAAP profitability if licensing revenue is lumpy.
⚖️ Verdict: 🟢
Bullish. The successful monetization of their underlying semiconductor technology (Butterfly Embedded) drastically changes the company's total addressable market and margin profile. The leap to positive operating cash flow proves the model is viable.
Key Themes
Software & Services Growth Accelerating Dramatically
Accelerating. The Software and Other Services segment exploded, up 76% YoY from $7.6M in 24Q4 to $13.4M in 25Q4. This was primarily driven by the Midjourney partnership but also includes reduced software amortization costs. This mix shift is highly favorable for the company, pushing adjusted gross margins to a record 67.5%.
International Sales Trajectory Reversing
Reversing. While US revenue surged 55% YoY (buoyed by Midjourney), International revenue fell 6% YoY to $4.7M. This breaks a streak of positive international growth seen earlier in the year (+9% in Q1, +19% in Q2, +4% in Q3). Management attributed the decline to tough comparisons against initial stocking orders from new distributors in 24Q4, which flags a lack of sustained retail-level demand overseas.
HomeCare Commercialization Timeline Decelerating
Decelerating. Throughout early 2025, management explicitly guided toward finalizing the first commercial agreement for its Butterfly HomeCare initiative by 'year-end 2025'. In this Q4 release, the timeline has quietly slipped, with the company now 'anticipating finalizing its first commercial HomeCare agreement by mid-2026, with revenue contributions forecasted as early as late 2026.' This delay pushes a major potential catalyst (previously sized at $40M-$60M) further out.
Next-Gen Hardware Investment Stabilizing
Stable. The company is successfully maintaining its R&D roadmap without blowing out costs. R&D expense actually fell slightly to $36.3M for FY25 (down from $37.8M in FY24). Despite this cost control, Butterfly successfully moved its fifth-generation P5.1 chip into production and advanced the Apollo AI chip, securing its long-term hardware moat.
OpEx Base Expanding Despite Path to Profitability
Accelerating. Total operating expenses in Q4 reached $37.9M, up 22% from $31.0M a year ago. Even excluding stock-based compensation and other non-cash expenses, cash OpEx was $26.2M vs $25.4M. The company cited investments in the sales force and client experience. If licensing revenue proves to be lumpy, this higher fixed cost base could pressure margins in future quarters.
Other KPIs
Reversing drastically from Q3's negative margin (-17.5% due to inventory write-downs). More importantly, it is a significant expansion from 61.4% in 24Q4, driven heavily by the high-margin Midjourney licensing revenue and lower historical software amortization.
A massive improvement from the $88.8 million reported at the end of FY24. The increase was driven primarily by an $81 million equity raise in Q1, but defended fiercely throughout the year by strict operational discipline, culminating in the $6.3M positive operating cash flow in Q4.
Guidance
Accelerating. The midpoint of $119M implies a 21.9% YoY growth rate compared to FY25's $97.6M. This indicates management expects the combination of core growth and new Embedded/Midjourney revenue to outpace the 19% growth achieved in FY25.
Accelerating improvement. Down from a $26.5M loss in FY25 and a $38.9M loss in FY24. The midpoint ($23M) shows a clear, consistent trajectory toward operational breakeven, largely supported by the expanding gross margins of the software and licensing business.
Key Questions
Midjourney Deal Cadence
The Midjourney partnership added $6.8M in Q4 out of an expected $74M over five years. How should we model this revenue moving forward? Will it be lumpy milestone payments, or recognized ratably over the next 19 quarters?
International Contraction
International sales fell 6% this quarter. Was this entirely due to lapping an initial stocking order, or are you seeing pushback on the higher price point of the iQ3 in budget-constrained overseas markets?
HomeCare Agreement Delay
The commercialization timeline for HomeCare has shifted from 'year-end 2025' to 'mid-2026'. What specific hurdles are preventing the pilot partner from signing the commercial contract?
