cause its views to change.

Use of Estimates

Unless otherwise indicated, information contained in this presentation concerning our industry, competitive position and the markets in which Ouster operates is based on information from independent industry and research organizations, other third-party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts and other third-party sources, as well as data from our internal research, and are based on assumptions made by the Company upon reviewing such data, and the Company's experience in, and knowledge of, such industry and markets, which the Company believes to be reasonable. In addition, projections, assumptions and estimates of the future performance of the industry in which Ouster operates and its future performance are necessarily subject to uncertainty and risk due to a variety of factors, including those described above and in our filings with the SEC. These and other factors could cause results to differ materially from those expressed in the estimates made by independent parties and by the Company.

• Strategic Customer Agreements" or "SCAs" establish a multi-year purchase and supply framework for Ouster and the customer, and include details about customer programs and applications where the customer intends to use Ouster products. SCAs also include multi-yearnon-binding customer forecasts (typically of three to five years in length) giving Ouster visibility to the customer's long-term purchasing requirements, mutually agreed upon pricing over the duration of the agreement, and in certain cases include multi-year binding purchase commitments. "Contracted revenue opportunity"
  represents the sum of both binding purchase commitments and non-binding forecasts. No assurances can be given that non-binding forecasts will mature into binding purchase commitments, or that any contracted revenue opportunity will result in revenue. No additional revenue opportunity beyond the customer's actual forecast has been imputed.
