"Ouster, Inc. (OUST) is a company at the forefront of sensing technology, primarily known for its advanced digital LiDAR (Light Detection and Ranging) sensors. These sensors act like eyes for machines, using lasers to create detailed 3D maps of their surroundings.\n\n1. The Business Model (How They Make Money)\n\nOuster's core business revolves around designing and selling these high-tech digital LiDAR sensors. These sensors are crucial components for a wide range of applications, including self-driving cars, industrial robots that automate tasks in factories and warehouses, and ""smart city"" infrastructure that can monitor traffic or detect hazards.\n\nThe company's main way of making money is through the sale of these physical sensors. However, Ouster is also expanding its reach. They recently acquired Stereolabs, which added vision-based cameras, artificial intelligence (AI) computing power, and specialized software to their offerings. This move aims to create a more complete ""sensing and perception platform"" for what they call ""Physical AI,"" which helps machines understand and interact with the real world. Ouster is also focusing on developing ""software-attached"" services, like their Gemini and BlueCity platforms, which provide analytics for smart infrastructure and could lead to more recurring revenue in the future.\n\nIn the first quarter of 2026, Ouster reported total revenue of $49 million. Of this, product revenue, which comes directly from selling their sensors and related hardware, was $48 million. For the full year 2025, Ouster's total revenue was $169.4 million. This included $147 million from product sales and approximately $22.8 million from intellectual property (IP) royalties, which were largely one-time payments related to long-term licensing agreements.\n\n2. The Metrics That Matter Most\n\nFor Ouster, a growing technology company that is still investing heavily in its future, here are the most important numbers to watch:\n\n* Revenue: This metric simply tells you the total amount of money the company brings in from selling its products and services. For Ouster, it's a critical indicator of how quickly they are growing and how much demand there is for their LiDAR sensors and new software solutions. Since they are a growth company, increasing revenue shows they are successfully getting their technology into more hands and applications. In Q1 2026, Ouster's revenue was $49 million, a 49% increase from the same period last year.\n\n* Gross Margin: This number shows how much profit Ouster makes from its products after subtracting the direct costs of making and selling them (like materials and manufacturing). It's expressed as a percentage of revenue. A higher gross margin means the company is more efficient at producing its goods and has more money left over to cover other business costs like research and development, and sales. For a hardware company like Ouster, improving gross margin is key to becoming profitable. Ouster's GAAP gross margin was 43% in Q1 2026.\n\n* R&D Expenses (Research & Development Expenses): This represents the money Ouster spends on creating new and improved products and technologies. For a company in a rapidly evolving tech sector like LiDAR, investing in R&D is absolutely vital to stay competitive and develop the next generation of sensors and software. High R&D spending indicates the company is committed to innovation, which is crucial for its long-term success. While specific Q1 2026 R&D figures were not explicitly detailed, Ouster's operating expenses, which include R&D, were noted to be elevated as they scale their platform. In Q3 2025, R&D expenses increased by 18% year-over-year to $17.8 million.\n\n* Operating Cash Flow: This metric shows how much cash the company generates from its regular business operations before accounting for things like investments or financing activities. For a company that isn't consistently profitable yet, positive operating cash flow is a sign that the core business is starting to stand on its own feet and can fund its day-to-day activities without needing to borrow more money or sell new stock. In Q1 2026, Ouster reported net cash used in operating activities of $7.3 million.\n\n3. How to Value This Company\n\n* P/Sales (Price-to-Sales Ratio): This valuation metric compares the company's total stock market value (its ""market capitalization"") to its total revenue over the last year. You calculate it by dividing the company's market capitalization by its total revenue. We use P/Sales for Ouster because the company is still in a growth phase and has not yet achieved consistent profits (meaning its net income is often negative). When a company isn't consistently profitable, traditional valuation metrics like the Price-to-Earnings (P/E) ratio don't make sense. P/Sales allows investors to compare Ouster's value relative to its sales, giving an idea of how much investors are willing to pay for each dollar of revenue the company generates. A lower P/Sales ratio might suggest the stock is ""cheaper"" compared to its sales, while a higher ratio could mean investors expect very strong future growth."
