Ouster Announces Results for First Quarter 2026

Record product revenue, achieving 13th straight quarter of growth

Lidar and camera shipments of more than 12,600 units

New Rev8 OS digital lidar with native color sensing, 2x range and resolution, and functional safety

SAN FRANCISCO, CA – [May 5, 2026 at 4:05 PM ET] – Ouster, Inc. (Nasdaq: OUST) (“Ouster” or the “Company”), a leader in sensing and perception for Physical AI, announced today financial results for the three months ended March 31, 2026.

“Our first quarter demonstrated strong execution across our portfolio, delivering record product revenue and validating the growing demand for our solutions across key markets. We won new million-dollar contracts for Ouster BlueCity and secured several million-dollar deals to power industrial automation. Stereolabs has already proven to be a perfect complement, and the rapid integration and commercial success of our expanded camera vision portfolio was a tailwind during the quarter, with strong demand from companies building foundational AI models and advanced robotics platforms,” said Ouster CEO Angus Pacala.

“We are continuing the momentum of our unified sensing and perception platform with the introduction of our revolutionary Rev8 OS family, powered by our next-generation L4 Ouster Silicon. This launch represents a paradigm shift in AI perception as Rev8 sets a new standard for sensing, featuring the world’s first native-color lidar sensors with industry-leading resolution, range, and reliability designed for functional safety, affordability, and scale. By combining native color and perception across our entire product portfolio, we have solidified Ouster’s role as the foundational sensing and perception platform for Physical AI as we provide unified products and solutions that accelerate customer innovation and unlock new applications that sense, think, act, and learn in the physical world.”
