SUMMARY RISK FACTORS

Our business is subject to numerous risks and uncertainties, including those described in Part I, Item 1A. “Risk Factors” in this Annual Report on Form 10-K. You should carefully consider these risks and uncertainties when investing in our common stock. The principal risks and uncertainties affecting our business include the following:

•Our products are frequently used in applications that are subject to evolving regulations and standards.

•Our limited operating history makes it difficult to evaluate our future prospects and the risks and challenges we may encounter.

•We have incurred significant losses to date and may never achieve or sustain profitability. If we are unable to overcome our limited sales history and establish and maintain confidence in our long-term business prospects among customers in our target markets or if our revenue opportunity does not materialize into sales and revenue, then our financial condition, operating results, business prospects and access to capital may suffer materially.

•Our revenue and margins could be adversely affected if we fail to maintain competitive average selling prices, high sales volumes, and/or fail to reduce product costs.

•We are subject to the risk of cancellation or postponement of our contracts with customers or the unsuccessful implementation of our products, which may adversely affect our business, results of operations and financial condition.

•We currently target many customers that are large corporations with substantial negotiating power and exacting product standards. If we are unable to sell our products to these customers, our prospects and results of operations will be adversely affected.

•We compete against established market participants that have substantially greater resources than us and against known and unknown market entrants who may disrupt our target markets. If our products are not selected for inclusion in our target markets, our business will be materially and adversely affected.

•Market adoption of lidar remains uncertain, and it is difficult to forecast long-term end-customer adoption rates and demand for our products.

•Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide and could cause our stock price to fluctuate or decline.

•If we choose to acquire or invest in other new businesses, products, or technologies, such acquisitions or investments may not be completed or result in the anticipated benefits and may present risks not originally contemplated and adversely impact our business.

•Key components in our products come from limited or single source third-party suppliers, and we expect to rely on third parties to manufacture a significant portion of our products for the foreseeable future. Interruptions in our relationships with these third parties could adversely impact our business.

•We may require additional capital in order to execute our business plan, which may not be available on terms acceptable to us, or at all.

•We may not be able to adequately protect orenforce our intellectual property rights or prevent competitors or other unauthorized parties from copying or reverse engineering our technology.
