Ouster (OUST) Q1 2026 earnings review
Core Product Accelerates While One-Time Royalties Roll Off
Ouster delivered $49 million in Q1 revenue, a 49% YoY increase but a 22% sequential drop. However, the sequential decline is entirely optical, driven by the absence of a $21 million one-time IP royalty recognized in 24Q4. Stripping out the royalty noise, core Product Revenue is actually accelerating, growing 55% YoY and 18% sequentially to $48 million. Profitability metrics took a sequential hit as the 100% margin royalty revenue rolled off, driving GAAP net loss down to $17 million and Adjusted EBITDA loss to $7 million. Q2 guidance of $49.5-$52.5 million indicates a stable trajectory as the newly acquired Stereolabs business fully integrates into the top line.
🐂 Bull Case
Product revenue grew 18% sequentially and 55% YoY. Moving 12,600 sensors in a single quarter proves Ouster is successfully shifting customers from pilot testing to volume production.
The integration of Stereolabs provides a complete camera vision portfolio, allowing Ouster to sell unified perception packages rather than standalone hardware components.
🐻 Bear Case
Without the padding of the Q4 royalty payment, Net Income immediately reversed back to a $17 million loss, highlighting the persistent cash burn inherent to scaling hardware production.
Total operating expenses rose to $40 million from $36.5 million sequentially, largely due to integration costs and R&D for next-generation silicon.
⚖️ Verdict: 🟢
Bullish. The optical revenue miss sequentially hides a fundamental breakout in product unit economics. Moving 12,600 sensors in Q1 and guiding for $51 million at the midpoint in Q2 shows the core hardware and software business is rapidly scaling.
Key Themes
Stereolabs Integration Opens Vision Market
The newly closed Stereolabs acquisition immediately impacted Q1. Management cited 'rapid integration and commercial success' of the expanded camera vision portfolio. This represents a strategic shift from being a pure lidar manufacturer to a unified 'Physical AI' perception platform, significantly increasing cross-sell opportunities across advanced robotics platforms.
Rev8 OS and L4 Silicon Rollout
Ouster announced its new Rev8 OS family, powered by the next-generation L4 Silicon. This is a massive product upgrade, bringing the world's first native-color lidar sensors to market. By doubling resolution and range while integrating native color, Ouster is creating a hardware moat that forces competitors into a cycle of catch-up.
AI Macro Tailwinds Accelerating Demand
The company explicitly called out macro-level demand from 'companies building foundational AI models'. As broader tech shifts toward physical AI and spatial computing, Ouster's unified sensing solutions are becoming critical infrastructure, providing durable secular growth outside of traditional automotive or defense constraints.
Gross Margins Reversing to Baseline
GAAP gross margin compressed dramatically, falling 1,700 basis points sequentially to 43% from 60% in 25Q4. While management cites volume growth and operating efficiencies lifting profitability YoY (up from 41% in 25Q1), the sequential drop highlights how reliant the company was on the Q4 one-time IP license royalty to project high profitability.
Inventory Build Contradicts Efficiency Claims
Despite management touting volume growth and operating efficiencies, inventory spiked from $23.6 million in 25Q4 to $29.9 million in 26Q1, a 27% sequential increase. This rate of inventory build outpaces the 18% sequential product revenue growth, suggesting either a strategic buildup for Stereolabs integration, supply chain friction, or slower-than-expected sensor sell-through.
Operating Expense Creep
Total operating expenses rose to $40.1 million in Q1, up 10% sequentially from $36.5 million in Q4. The increase was broad-based, with General and Administrative expenses hitting $16.1 million (up from $14.5 million sequentially). If OpEx continues accelerating, it will push the timeline for operational cash flow breakeven further into the future.
Other KPIs
Decelerating. While it is an improvement from the -$7.8 million recorded a year ago (25Q1), it is a sharp sequential decline from the +$13.1 million generated in 25Q4. Adjusting for the massive Q4 royalty, core business unit economics are stable but remain fundamentally cash-negative.
Accelerating. The company shipped over 12,600 total sensors (lidar + cameras), with lidar representing 65% of the mix. This translates to roughly 8,190 lidar sensors, beating the previous Q4 record of 8,100 units. Volume scale is clearly executing.
Guidance
Accelerating sequentially. At the midpoint of $51 million, this implies a 5% QoQ increase over Q1's $48.6 million and a 45% YoY increase compared to 25Q2's $35 million. Management notes this includes the first full quarter of Stereolabs operations.
Key Questions
Stereolabs Revenue Contribution
How much of the $48 million in Q1 product revenue was organically generated by Ouster hardware versus the initial consolidated weeks of Stereolabs operations?
Rev8 Margin Impact
With the rollout of the Rev8 OS and native-color lidar sensors, what is the expected impact on ASPs (Average Selling Prices) and structural gross margins in the back half of 2026?
Inventory Management
Inventory rose 27% sequentially to nearly $30 million. Is this a deliberate pre-build ahead of expected Q2 volume ramps, or a byproduct of integrating Stereolabs' supply chain?
