As an innovation-driven lidar company, Ouster is led by an experienced management team with deep technical knowledge and strong business momentum. Since inventing their digital lidar in 2015, Ouster has revolutionized lidar technology, creating a digital solution that we believe is capable of disrupting the existing analog solutions in the market.

Simple is Elegant. Digital is Powerful.

Ouster is a leading provider of high-resolution digital lidar sensors that give advanced 3D vision to robots, vehicles, and fixed infrastructure assets, allowing each to understand and visualize the surrounding world, and enabling safe autonomy. With its patented digital lidar technology, Ouster designs and manufactures sensors that it believes are the highest performing, lowest cost lidar solution available today across each of its four target markets: 1) industrial automation; 2) smart infrastructure; 3) robotics; and 4) automotive.

Angus Pacala and Mark Frichtl founded Ouster with a vision that, with the right combination of lower prices and higher performance, lidar would become ubiquitous and make the world smarter, safer, and more efficient, like other sensor technologies before it. This vision required rethinking the architecture behind high-performance lidar with an explicit focus on manufacturability and affordability. Their work resulted in the invention of Ouster's high-performance digital lidar, based on custom-designed semiconductors and optical innovations, which they brought to market in 2018.

Ouster's digital lidar now allows for low-cost customization that enables broad industry applications while maintaining a streamlined manufacturing process designed for scalability. With over 75 combinations of range, field of view, and resolution configurations, Ouster has one of the most complete lineups of lidar sensors on the market today. Its sensors are currently used by hundreds of customers globally, providing vision to autonomous vehicles and robots in applications ranging from mining and construction to cars and trucks, to smart city infrastructure.

Transaction Overview

The business combination values Ouster at an approximately $1.6 billion pro forma post-money enterprise value at a share price of $10.00, assuming no redemptions by Colonnade shareholders and no purchase price adjustments. All current Ouster stockholders will roll the entirety of their existing equity holdings into the combined company. The $100 million fully committed common stock PIPE includes investments from existing investors, Cox Enterprises, Fontinalis Partners, and WWJr Enterprises. The boards of directors of both Ouster and Colonnade have unanimously approved the proposed business combination, which is expected to be completed in the first half of 2021, subject to, among other things, the approval by Colonnade's shareholders and Ouster's shareholders, satisfaction of the minimum cash condition, which is equal to the $100 million committed common stock PIPE investment at $10.00 per share obtained in connection with the entry into the Merger Agreement, and certain other customary closing conditions stated in the Merger Agreement.

Following completion of the business combination, Ouster will retain its experienced management team. Co-Founder Angus Pacala will continue to serve as CEO, co-founder Mark Frichtl will continue as CTO, and Anna Brunelle will continue to serve as CFO. Remy Trafelet will join the Ouster board of directors upon closing of the business combination.
