All statements contained in this Quarterly Report on Form 10-Q other than statements of historical fact, including statements regarding our future operating results and financial position, our business strategy and plans, potential acquisitions, market growth and trends, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “preliminary,” “likely,” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including Ouster’s limited operating history and history of losses; the negotiating power and product standards of its customers; fluctuations in its operating results; cancellation or postponement of contracts or unsuccessful implementations; the adoption of its products and the growth of the lidar market generally; its ability to grow its sales and marketing organization; substantial research and development costs needed to develop and commercialize new products; the competitive environment in which it operates; selection of our products for inclusion in target markets; its future capital needs; its ability to use tax attributes; its dependence on key third party suppliers, in particular Benchmark Electronics, Inc., and manufacturers; ability to maintain inventory and the risk of inventory write-downs; inaccurate forecasts of market growth; its ability to manage growth; the creditworthiness of our customers; risks related to acquisitions; risks related to international operations; risks of product delivery problems or defects; costs associated with product warranties; its ability to maintain competitive average selling prices or high sales volumes or reduce product costs; conditions in its customers industries; its ability to recruit and retain key personnel; its use of professional employer organizations; its ability to adequately protect and enforce its intellectual property rights; its ability to effectively respond to evolving regulations and standards; risks related to operating as a public company; risks related to the COVID-19 pandemic; and risks related to certain of our warrants being accounted for as liabilities. Other risk factors include the important factors described in the section titled “Risk Factors” in the final prospectus and definitive proxy statement, dated February 12, 2021 (the “Proxy Statement/Prospectus”), as updated by the risk factors disclosed in the section titled “Risk Factors” in our Form 8-K, filed with the Securities and Exchange Commission (the “SEC”) on February 12, 2021 and March 15, 2021, respectively, and as further updated in this Quarterly Report on Form 10-Q under Part II. Item 1A. “Risk Factors,” and in our other filings with the SEC, that may cause our actual results, performance or achievements to differ materially and adversely from those expressed or implied by the forward-looking statements.

Any forward-looking statements made herein speak only as of the date of this Quarterly Report on Form 10-Q, and you should not rely on forward-looking statements as predictions of future events.

OUSTER, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1 – Description of Business and Basis of Presentation

Description of Business

Ouster, Inc. was incorporated in the state of Delaware on June 4, 2020. The Company’s operating subsidiary, Ouster Technologies, Inc. (“OTI” and prior to the Merger (as defined below), named Ouster, Inc.), was incorporated in the state of Delaware on June 30, 2015. The Company is a leading provider of high-resolution digital lidar sensors that offer advanced 3D vision to machinery, vehicles, robots, and fixed infrastructure assets, allowing each to understand and visualize the surrounding world and ultimately enabling safe operation and ubiquitous autonomy. Unless the context otherwise requires, references in this subsection to “the Company” refer to the business and operations of OTI (formerly known as Ouster, Inc.) and its consolidated subsidiaries prior to the Merger (as defined below) and to Ouster, Inc. (formerly known as Colonnade Acquisition Corp.) and its consolidated subsidiaries following the consummation of the Merger.

Colonnade Acquisition Corp. (“CLA”), the Company’s predecessor, was originally a blank check company incorporated as a Cayman Islands exempted company on June 4, 2020. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On March 11, 2021, CLA consummated a merger with the Company pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) dated as of December 21, 2020, details of which are included below.

Basis of Presentation and Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries (all of which are wholly owned) and have been prepared in conformity with U.S. generally accepted accounting principles (“US GAAP”) applicable to interim periods. The functional currency for the Company is the United States dollar. All intercompany balances and transactions have been eliminated in consolidation.

The unaudited condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the periods shown. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2020 and the notes related thereto, included as Exhibit 99.1 to the Form 8-K filed with the Securities and Exchange Commission (“SEC”) on March 15, 2021. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. The results of operations for any interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any other future years or interim periods.

Liquidity

The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis. The Company has experienced recurring losses from operations, and negative cash flows from operations. As of March 31, 2021, the Company had an accumulated deficit of approximately $230 million. The Company has historically financed its operations primarily through the Merger and related transactions, the sale of convertible notes, equity securities, proceeds from debt and, to a lesser extent, cash received from sales. Management expects significant operating losses and negative cash flows from operations to continue for the foreseeable future. The Company expects to continue investing in product development and sales and marketing activities. The long-term continuation of the Company’s business plan is dependent upon the generation of sufficient revenues from its products to offset expenses. In the event that the Company does not generate sufficient cash flows from operations and is unable to obtain funding, the Company will be forced to delay, reduce, or eliminate some or all of its discretionary spending, which could adversely affect the Company’s business prospects, ability to meet long-term liquidity needs or ability to continue operations. The Company has concluded that its cash and cash equivalents as of March 31, 2021 are sufficient for the Company to continue as a going concern for at least one year from the date these unaudited condensed consolidated financial statements are available for issuance.

Merger Agreement with Colonnade Acquisition Corp. and Beam Merger Sub, Inc.

On December 21, 2020, OTI entered into the Merger Agreement with CLA and Beam Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and subsidiary of CLA. OTI’s board of directors unanimously approved OTI’s entry into the Merger Agreement, and on March 11, 2021, the transactions contemplated by the Merger Agreement were consummated. Pursuant to the terms of the Merger Agreement, (i) CLA domesticated as a corporation incorporated under the laws of the State of Delaware and changed its name to “Ouster, Inc.” and (ii) Merger Sub merged with and into OTI (such transactions contemplated by the Merger Agreement, the “Merger”), with OTI surviving the Merger.

As a result of the Merger, among other things, (1) each of the then issued and outstanding 5,000,000 CLA Class B ordinary shares, par value $0.0001 per share, of CLA (the “CLA Class B ordinary shares”) converted automatically, on a one-for-one basis, into a CLA Class A ordinary share (as defined below), (2) immediately following the conversion described in clause (1), each of the then issued and outstanding 25,000,000 Class A ordinary shares, par value $0.0001 per share, of CLA (the “CLA Class A ordinary shares”), converted automatically, on a one-for-one basis, into a share of common stock, par value $0.0001 per share, of Ouster (the “Ouster common stock”), (3) each of the then issued and outstanding 10,000,000 redeemable warrants of CLA (the “CLA warrants”) converted automatically into a redeemable warrant to purchase one share of Ouster common stock (the “Public warrants”) pursuant to the Warrant Agreement, dated August 20, 2020 (the “Warrant Agreement”), between CLA and Continental Stock Transfer & Trust Company (“Continental”), as warrant agent, and (4) each of the then issued and outstanding units of CLA that had not been previously separated into the underlying CLA Class A ordinary shares and underlying CLA warrants upon the request of the holder thereof (the “CLA units”), were cancelled and entitled the holder thereof to one share of Ouster common stock and one-half of one Public warrant, and (5) each of the then issued and outstanding 6,000,000 private placement warrants of CLA (the “Private Placement warrants”) converted automatically into a Public warrant pursuant to the Warrant Agreement. No fractional Public warrants were issued upon separation of the CLA units.

Immediately prior to the effective time of the Merger, (1) each share of OTI’s Series B Preferred Stock, par value $0.00001 per share (the “OTI Preferred Stock”), converted into one share of common stock, par value $0.00001 per share, of OTI (the “OTI common stock” and, together with OTI Preferred Stock, the “OTI Capital Stock”) (such conversion, the “OTI Preferred Conversion”) and (2) all of the outstanding warrants to purchase shares of OTI Capital Stock were exercised in full or terminated in accordance with their respective terms (the “OTI Warrant Settlement”).

As a result of and upon the closing of the Merger, among other things, all shares of OTI Capital Stock (after giving effect to the OTI Warrant Settlement) outstanding immediately prior to the closing of the Merger together with shares of OTI common stock reserved in respect of options to purchase shares of OTI common stock and restricted shares of OTI common stock (together, the “OTI Awards”) outstanding immediately prior to the closing of the Merger that were converted into awards based on Ouster common stock, were cancelled in exchange for the right to receive, or the reservation of, an aggregate of 150,000,000 shares of Ouster common stock (at a deemed value of $10.00 per share), which, in the case of OTI Awards, were shares underlying awards based on Ouster common stock, representing a fully-diluted pre-transaction. Upon closing of the Merger, the Company received gross proceeds of $299.9 million from the Merger and private offering, offset by $8.5 million of pre-merger costs relating to CLA and offerings costs of $26.6 million.

The Merger was accounted for as a reverse recapitalization under generally accepted accounting principles (“GAAP”). Under this method of accounting, CLA is treated as the “acquired” company for financial reporting purposes. This determination is primarily based on OTI stockholders comprising a relative majority of the voting power of the Company and having the ability to nominate the members of the board of directors of the Company after the Merger, OTI’s operations prior to the Merger comprising the only ongoing operations of the Company following the Merger, and OTI’s senior management prior to the Merger comprising a majority of the senior management of the Company following the Merger. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of OTI with the Merger being treated as the equivalent of OTI issuing stock for the net assets of CLA, accompanied by a recapitalization whereby no goodwill or other intangible assets are recorded. Transactions and balances prior to the Merger are those of OTI. The shares and net loss per share available to holders of OTI’s common stock prior to the Merger have been retroactively restated as shares reflecting the exchange ratio established in the Merger Agreement.

On December 21, 2020, concurrently with the execution of the Merger Agreement, CLA entered into subscription agreements with certain institutional and accredited investors (collectively, the “PIPE Investors”), pursuant to which the PIPE Investors agreed to purchase, in the aggregate, 10,000,000 shares of Ouster common stock at $10.00 per share for an aggregate commitment amount of $100,000,000 (the “PIPE Investment”), a portion of which was funded by certain affiliates of

10

Colonnade Sponsor LLC, CLA’s sponsor (the “Sponsor”). The PIPE Investment was consummated substantially concurrently with the closing of the Merger.

Note 2 – Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Items subject to such estimates and assumptions include, but are not limited to, the useful lives of long-lived assets, revenue recognition, sales return reserve, allowances for inventory valuation, the realizability of deferred tax assets, the measurement of stock-based compensation, and the valuation of the Company’s various financial instruments (including preferred stock and warrants). The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. On an ongoing basis, the Company evaluates these assumptions, judgments and estimates. Actual results may differ from these estimates.

The Company is not aware of any specific event or circumstances that would require an update to estimates, judgments or assumptions or a revision to the carrying value of the Company’s assets or liabilities as of the date these financial statements were available to be issued. These estimates, judgments and assumptions may change in the future, as new events occur, or additional information is obtained.

Impact of the COVID-19 Pandemic

The Company has been actively monitoring the COVID-19 situation and its impact on the Company’s business. In response to the pandemic, numerous state and local jurisdictions have imposed “shelter-in-place” orders, quarantines and other restrictions. In the United States, governmental authorities have recommended, and in certain cases required, that elective, specialty and other procedures and appointments, be suspended or canceled. Similarly, in March and December 2020, the governor of California, where the Company’s headquarters are located, issued “stay at home” orders limiting non-essential activities, travel and business operations. Such orders or restrictions have resulted in reduced operations at the Company’s headquarters (including its manufacturing facility), work stoppages, slowdowns and delays, travel restrictions and cancellation of events and have restricted the efforts of the Company’s sales representatives, thereby significantly and negatively impacting the Company’s operations.

The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain it or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets. The situation surrounding COVID-19 remains fluid and the potential for a material impact on the Company increases the longer the virus impacts the level of economic activity in the United States and globally.

Foreign Currencies

The functional currency of the Company and its subsidiaries is the U.S. dollar. Accordingly, non-U.S. dollar denominated monetary assets and liabilities are re-measured into U.S. dollars at the exchange rates in effect at the reporting date, non-monetary assets and liabilities are recorded at historical rates, and revenue and expenses are recorded at average exchange rates in effect during each reporting period. Foreign currency transaction gains and losses are recorded in other income (expense), net in the unaudited condensed consolidated statements of operations and comprehensive loss.

Net loss per common share

The Company follows the two-class method when computing net loss per common share. The two-class method determines net loss per common share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

Basic net loss per common share attributable to common stockholders is computed by dividing the net loss by the weighted average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders is

11

computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per common share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of common stock equivalents.

The Company’s redeemable convertible preferred stock contractually entitled the holders of such shares to participate in dividends but does not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the three months ended March 31, 2021 and 2020.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive income (loss). The Company has no components of other comprehensive loss. Therefore, net loss equals comprehensive loss for all periods presented and, accordingly, the Consolidated Statements of Comprehensive Loss is not presented in a separate statement.

Segment Information

The Company operates as one reportable and operating segment, which relates to the sale of lidar sensor kits. The Company’s chief operating decision maker is its chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Revenue Recognition

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, the Company performs the following five steps:

1) Identify the contract with a customer

The Company considers the terms and conditions of revenue contracts and its customary business practices in identifying contracts under ASC 606. It is determined that a contract with a customer exists when the contract is approved, each party’s rights regarding the product or services to be transferred and the payment terms for the product or services can be identified, it is determined that the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgement in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer.

2) Identify the performance obligations in the contract

Performance obligations promised in a contract are identified based on the product or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or services is separately identifiable from other promises in the contract. The Company’s performance obligations consist of (i) sale of lidar sensor kits and (ii) product development and validation services.

3) Determine the transaction price

The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring product or services to the customer. Variable consideration is included in the transaction price if the Company judges that it is probable that a significant future reversal of cumulative revenue under the contract will not occur. The Company does not have a material amount of variable consideration in its agreements with customers. None of the Company’s contracts contain a significant financing component. All taxes assessed by a governmental authority on a specific revenue-producing transaction collected by the Company from a customer are excluded from the transaction price.

12

4) Allocate the transaction price to performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). In each of the three months ended March 31, 2021 and 2020, the Company did not have a material volume of contracts that required the allocation of transaction price to multiple performance obligations.

5) Recognize revenue when or as the Company satisfies a performance obligation

Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Revenue is recognized when control of products or services is transferred to customers, in an amount that reflects the consideration that the Company expects to receive in exchange for those products or services. The Company generates all of its revenue from contracts with customers and applies judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition.

Nature of Products and Services and Revenue Recognition

The majority of the Company’s revenue comes from product sales of lidar sensor kits to customers. Revenue is recognized at a point in time when control of the goods is transferred to the customer, generally occurring upon shipment. Product sales to certain customers may require customer acceptance due to performance acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon the expiration of the customer acceptance period. Amounts billed to customers related to shipping and handling are classified as revenue, and the Company has elected to recognize the cost of shipping activities that occur after control has transferred to the customer as a fulfillment cost rather than a separate performance obligation. All related shipping costs are accrued and recognized within cost of revenue when the related revenue is recognized. Taxes collected from customers and remitted to governmental authorities are excluded from revenue on the net basis of accounting. Accounts receivable are due under normal trade terms, typically three months or less. Revenue from sale of lidar sensor kits, which are recognized at a point in time, was approximately $6.6 million and $2.3 million in the three months ended March 31, 2021 and 2020, respectively.

Arrangements with Multiple Performance Obligations

When a contract involves multiple performance obligations, the Company accounts for individual performance obligation separately if the customer can benefit from the performance obligation on its own or with other resources that are readily available to the customer and the performance obligation is separately identifiable from other promises in the arrangement. The consideration is allocated between separate performance obligations in proportion to their estimated standalone selling price. The standalone selling price reflects the price the Company would charge for a specific performance obligation if it were sold separately in similar circumstances and to similar customers.

The Company provides standard product warranties for a term of typically two years to ensure that its lidar sensors comply with agreed-upon specifications. Standard warranties are considered to be assurance type warranties and are not accounted for as separate performance obligations.

Costs to obtain a contract

The Company expenses the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are expensed as incurred in sales and marketing expense in the Company’s consolidated statements of operations and comprehensive loss. The expense was $0.3 million for the three months ended March 31, 2021. No commission plan was in place and no expense was recognized for the three months ended March 31, 2020.

Right of return

The Company’s general terms and conditions for its contracts do not contain a right of return that allows the customer to return products and receive a credit, however it has in practice permitted returns of its sensor kits in limited circumstances up to six months after purchase. Allowances for sales returns, which reduce revenue, are estimated using historical experience and were immaterial as of March 31, 2021 and December 31, 2020. Actual returns in subsequent periods have been consistent with estimated amounts.

13

Remaining performance obligations

Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. The customer is not considered committed where they are able to terminate for convenience without payment of a substantive penalty under the contract. Additionally, as a practical expedient, the Company has not disclosed the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

Significant financing component

In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied. The expected timing difference between the payment and satisfaction of performance obligations for the vast majority of the Company’s contracts is one year or less; therefore, the Company applies a practical expedient and does not consider the effects of the time value of money. The Company’s contracts with customer prepayment terms do not include a significant financing component because the primary purpose is not to receive financing from the customers.

Contract modifications

The Company may modify contracts to offer customers additional products or services. Each of the additional products and services are generally considered distinct from those products or services transferred to the customer before the modification. The Company evaluates whether the contract price for the additional products and services reflects the standalone selling price as adjusted for facts and circumstances applicable to that contract. In these cases, the Company accounts for the additional products or services as a separate contract. In other cases where the pricing in the modification does not reflect the standalone selling price as adjusted for facts and circumstances applicable to that contract, the Company accounts for the additional products or services as part of the existing contract primarily on a prospective basis.

Judgments and estimates

Accounting for contracts recognized over time under ASC 606 involves the use of various techniques to estimate total contract revenue and costs. Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. The Company reviews and updates its contract-related estimates regularly, and records adjustments as needed. For those performance obligations for which revenue is recognized using a cost-to- cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made.

Contract assets

The Company had no contract assets as of March 31, 2021 or December 31, 2020.

Disaggregation of Revenues

The following table presents total revenues by geographic area based on the location products were shipped to and services provided (in thousands):

	Three Months Ended March 31,
	2021		2020
United States	$	1,858	$	1,274
Americas, excluding United States	366		71
Europe, Middle East and Africa	3,133		581
Asia and Pacific	1,254		374
Total	$	6,611	$	2,300

Restricted Cash

Restricted cash consists of certificates of deposit held by a bank as security for outstanding letters of credit. The Company had a restricted cash balance of $1.3 million and $1.3 million as of March 31, 2021 and December 31, 2020, respectively, which has been excluded from the Company’s cash and cash equivalents balances. The Company presented $0.3 million of the total amount of restricted cash within current assets on the condensed consolidated balance sheets as of March 31, 2021 and

14

December 31, 2020. The remaining restricted cash balance of $1.0 million and $1.0 million is included in non-current assets on the condensed consolidated balance sheets as of March 31, 2021 and December 31, 2020, respectively.

Concentrations of credit risk

Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, and restricted cash, and accounts receivable. Cash, cash equivalents and restricted cash are deposited with federally insured commercial banks in the United States and at times cash balances may be in excess of federal insurance limits. The Company generally does not require collateral or other security deposits for accounts receivable.

To reduce credit risk, the Company considers customer creditworthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms when determining the collectability of specific customer accounts. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to valuation allowance. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

Accounts receivable from the Company’s major customers representing 10% or more of total accounts receivable was as follows:

	March 31, 2021		December 31, 2020
Customer A	14	%	13	%
Customer B	*		23	%

* Customer accounted for less than 10% of total accounts receivable in the period.

Revenue from the Company’s major customers representing 10% or more of total revenue was as follows:

	March 31, 2021		March 31, 2020
Customer B	*		12	%
Customer C	28	%	*
Customer D	*		18	%

* Customer accounted for less than 10% of total revenue in the period.

Concentrations of supplier risk

One supplier accounted for approximately 17% of total purchases during the three months ended March 31, 2021 and accounted for 48% of total accounts payable as of March 31, 2021. One supplier accounted for approximately 11% of total purchases during the three months ended March 31, 2020 and accounted for 23% of total accounts payable balance as of December 31, 2020.

Recently Issued Accounting Pronouncements not yet adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), to introduce a new impairment model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses (“ECL”). Under the new model, an entity is required to estimate ECL on available-for-sale (AFS) debt securities only when the fair value is below the amortized cost of the asset and is no longer based on an impairment being “other-than-temporary”. The new model also requires the impairment calculation on an individual security level and requires an entity to use the present value of cash flows when estimating the ECL. The credit-related losses are required to be recognized through earnings and non-credit related losses are reported in other comprehensive income. The ASU will be effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The Company does not believe the adoption of this new guidance will have a material impact on its unaudited condensed consolidated financial statements.

15

In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This ASU is effective for the Company for fiscal years beginning after December 15, 2020 and interim periods within annual periods beginning after December 15, 2021. Early adoption is permitted. The Company is currently evaluating the effect of the guidance on its unaudited condensed consolidated financial statements and disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and by improving consistent application of other areas of Topic 740. The new standard is effective for the Company for annual periods beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the effect of the guidance on its condensed consolidated financial statements and disclosures.

In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06). ASU 2020-06 simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separately present certain conversion features in equity. In addition, the amendments in the ASU also simplify the guidance in ASC 815-40, Derivatives and Hedging: Contracts in Entity’s Own Equity, by removing certain criteria that must be satisfied in order to classify a contract as equity, which is expected to decrease the number of freestanding instruments and embedded derivatives accounted for as assets or liabilities. Finally, the amendments revise the guidance on calculating earnings per share, requiring use of the if-converted method for all convertible instruments and rescinding an entity’s ability to rebut the presumption of share settlement for instruments that may be settled in cash or other assets. The new standard is effective for the Company for annual periods beginning December 15, 2023 and can be early adopted at the beginning of an annual period. The Company is currently evaluating the impact of the adoption of this ASU on the Company’s condensed consolidated financial statements.

Note 3. Fair Value of Financial Instruments

The Company applies the fair value measurement accounting standard whenever other accounting pronouncements require or permit fair value measurements. Fair value is defined in the accounting standard as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

•Level 1 - Quoted prices for identical instruments in active markets.

•Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•Level 3 - Instruments whose significant value drivers are unobservable.

On March 31, 2021, the Company’s Level 3 liabilities consisted of the Private Placement warrant liability. The determination of the fair value of warrant liability is discussed in Note 6.

On December 31, 2020, the Company’s Level 3 liabilities consisted of the redeemable convertible preferred stock warrant liability. The determination of the fair value of warrant liability is discussed in Note 6.

Money market funds are included within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

The fair value of the Private Placement warrant and redeemable convertible preferred stock warrant liabilities is based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. In determining the fair value of the warrant liabilities, the Company used the Black-Scholes option pricing model to estimate the fair value using unobservable inputs including the expected term, expected volatility, risk-free interest rate and dividend yield (see Note 6).

The following table presents a summary of the changes in the fair value of the Company’s Level 3 financial instruments (in thousands):

	Redeemable Convertible Preferred Stock Warrant Liability		Private Placement Warrant Liability		Derivative Liability

Note 5. Debt

Runway Growth Loan Agreement

On November 27, 2018, the Company entered into a Loan and Security Agreement with Runway Growth Credit Fund Inc. (“Runway Loan and Security Agreement”). The Runway Loan and Security Agreement provided for loans in an aggregate principal amount up to $10.0 million with a loan maturity date of November 15, 2021. The loan carried an interest rate equal to LIBOR plus 8.5%, unless LIBOR becomes no longer attainable or ceases to fairly reflect the costs of the lender, in which case the applicable interest rate shall be Prime Rate plus 6.0%. In an event of default, annual interest is increased by 5.0% above the otherwise applicable rate. The loan’s annual effective interest rate was approximately 16.4% for each of the three months ended March 31, 2021 and 2020.

In conjunction with the Runway Loan and Security Agreement, the Company issued a warrant to purchase 35,348 shares of Series A redeemable convertible preferred stock (the “Series A Preferred Stock”) of the Company (4.0% of original principal amount of $10.0 million, divided by the exercise price), with an exercise price of $11.3518 per share. The fair value of this warrant was estimated to be $0.1 million and accounted for as a debt discount. On August 5, 2019, in connection with the second amendment to the Runway Loan and Security Agreement, the Company amended the warrant issued to Runway Growth to increase the number of shares available to purchase to 53,023 shares of Series A Preferred Stock of the Company. The aggregate value of the warrants increased by $0.1 million after the warrant modification.

The warrants were exercised on March 11, 2021 and the warrant liability was remeasured to fair value with the increase recognized as a loss of $0.6 million for the three months ended March 31, 2021 within other income (expense), net in the consolidated statements of operations and comprehensive loss. The warrant liability was remeasured to fair value as of March 31, 2020 and the reduction was recognized as a gain of $0.2 million.

19

On March 26, 2021 the Company terminated the Runway Loan and Security Agreement and repaid the $7.0 million principal amount outstanding as well as interest and fees amounting to $0.4 million. The Company incurred no prepayment fees in connection with the termination and all liens and security interests securing the loan made pursuant to the Runway Loan and Security Agreement were released upon termination. As of March 31, 2021 and December 31, 2020, the outstanding principal balance of the loan was nil and $7.0 million, respectively.

Promissory notes

The Company issued a $5 million promissory note in January 2021 to certain current investors of the Company (or their respective affiliates) to help continue to fund the Company’s ongoing operations through the consummation of the Merger. The note accrued interest at a rate equal to LIBOR plus 8.5% per annum and was repaid on March 11, 2021 in accordance with its terms in connection with the consummation of the Merger.

Note 6. Warrants

Series A and B Redeemable Convertible Preferred Stock Warrants

On November 27, 2018, in connection with the execution of the Runway Loan and Security Agreement, OTI issued a warrant to purchase 35,348 shares of Series A Preferred Stock of OTI at an exercise price of $11.3518 per share (the “Runway warrant”). On August 5, 2019, in connection with the second amendment to the Runway Loan and Security Agreement, OTI amended the Runway warrant to increase the number of shares available to purchase to 53,023 shares of Series A Preferred Stock of OTI at an exercise price of $11.3518 per share.

The Runway warrants included a cashless exercise provision under which their holders could, in lieu of payment of the exercise price in cash, surrender the Runway warrant and receive a net amount of shares based on the fair market value of OTI’s stock at the time of exercise of the warrants after deduction of the aggregate exercise price. The Runway warrants contained provisions for adjustment of the exercise price and number of shares issuable upon the exercise of the Runway warrants in the event of certain stock dividends, stock splits, reorganizations, reclassifications, and consolidations.

The fair value of the warrants issued was recorded as of the date of initial issuance in the amount of $0.1 million. The subsequent issuance of warrants pursuant to the August 5, 2019 amendment to the Runway Loan and Security Agreement was recorded in the amount of $0.1 million. Immediately prior to the Merger, the warrants were exercised in full in accordance with their terms.

On April 3, 2020, in connection with the closing of the Series B redeemable convertible preferred stock, OTI issued a warrant to purchase 4,513,993 shares of Series B redeemable convertible preferred stock of the Company at an exercise price of $0.3323 per share (the “Series B warrants”). The Series B warrants could be exercised prior to the earliest to occur of (i) the 10 year anniversary of the date of issuance, (ii) the consummation of a liquidation transaction, or (iii) the consummation of an initial public offering. The Series B warrants included a cashless exercise provision under which their holders may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of the Company’s stock at the time of exercise of the warrants after deduction of the aggregate exercise price. The Series B warrants contained provisions for adjustment of the exercise price and number of shares issuable upon the exercise of the Series B warrants in the event of certain stock dividends, stock splits, reorganizations, reclassifications, and consolidations.

The Series B warrants were initially recognized as a liability at a fair value of $0.7 million. The Series B warrants were exercised on February 11, 2021 and the warrant liability was remeasured to fair value as of that date, resulting in a loss of $8.3 million for the three months ended March 31, 2021, classified within other income (expense), net in the consolidated statements of operations and comprehensive loss. Upon exercise redeemable convertible preferred stock converted into common stock pursuant to the conversion rate effective immediately prior to the Merger.

Historically, value was assigned to each class of equity securities using an option pricing model method (“OPM”). In September 2020, OTI began allocating the equity value using a hybrid method that utilizes a combination of the OPM and the probability weighted expected return method (“PWERM”). The PWERM is a scenario-based methodology that estimates the fair value of equity securities based upon an analysis of future values for OTI, assuming various outcomes. As the probability of a transaction with a special purpose acquisition company (“SPAC”) increased, the fair value of the redeemable convertible preferred stock warrant liability increased as of the date of the exercise.

The redeemable convertible preferred stock warrants were valued using the following assumptions under the Black-Scholes option-pricing model:

	Initial Issuance Date			Subsequent Issuance Date			December 31, 2020			February 11, 2021			March 11, 2021
Stock price	$	5.80		$	5.80		$	7.11		$	10.27		$	8.44

Private Placement Warrants

Simultaneously with the closing of the Company’s initial public offering (the “IPO”) in August 2020, the sponsor of CLA, Colonnade Sponsor LLC, purchased an aggregate of 6,000,000 Private Placement warrants at a price of $1.00 per warrant, for an aggregate purchase price of $6,000,000. The Private Placement warrants will become exercisable 12 months following the closing of the Company’s IPO, and will expire five years from the completion of the Merger, or earlier upon redemption or liquidation. Each Private Placement warrant will be exercisable for one Class A ordinary share at a price of $11.50 per share. On March 11, 2021, each outstanding Private Placement warrant automatically converted into a warrant to purchase one share of Ouster common stock pursuant to the Warrant Agreement.

The Private Placement warrants were initially recognized as a liability at a fair value of $19.4 million and the Private Placement warrant liability was remeasured to fair value as of March 31, 2021, resulting in a gain of $4.6 million for the three months ended March 31, 2021, classified within other income (expense), net in the condensed consolidated statements of operations and comprehensive loss.

The Private Placement warrants were valued using the following assumptions under the Black-Scholes option-pricing model:

	March 11, 2021			March 31, 2021
Stock price	$	12.00		$	8.50
Exercise price of warrant	11.5			11.5
Expected term (years)	5.00			4.95
Expected volatility	27.00		%	43.00		%
Risk-free interest rate	0.78		%	0.92		%

Public Warrants

The Company, in its IPO in August 2020, issued 20,000,000 units that each consisted one Class A ordinary share and one half warrant to purchase a Class A ordinary share, which we refer to as CLA warrants before the Merger and Public warrants after the Merger. These warrants may only be exercised for a whole number of shares, and no fractional warrants were issued or issuable upon separation of the units and only whole warrants will trade. The warrants will become exercisable 12 months following the closing of the Company’s IPO, and will expire five years from the completion of the Merger, or earlier upon redemption or liquidation. Each Public warrant will be exercisable at a price of $11.50 per share. On March 11, 2021, upon the closing of the Merger pursuant to the Merger Agreement (Note 1), each of the 9,999,996 outstanding warrants, as adjusted for any fractional warrants that were not issued upon separation, was converted automatically into a redeemable Public warrant to purchase one share of the Company’s common stock. The Public warrants were recognized as equity upon the Merger in the amount of $17.9 million.

Once the Public warrants become exercisable and prior to their expiration, the Company may redeem the Public warrants at a price of $0.01 per warrant, provided that the closing price of the Company’s common stock equals or exceeds $18.00 per share for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which the Company gives proper notice of such redemption to the warrants holders.

Note 7. Commitments and Contingencies

Letters of credit

In connection with two leases, the Company obtained two letters of credit from a bank as required by the lease agreements. If the Company defaults under the terms of the applicable lease, the lessor will be entitled to draw upon the letters of credit in the amount necessary to cure the default. The amounts covered by the letters of credit are collateralized by certificates of deposit, which are included in restricted cash on the condensed consolidated balance sheets as of March 31, 2021 and December 31, 2020. The outstanding amount of the letters of credit was $1.3 million as of March 31, 2021 and December 31, 2020.

Non-cancelable purchase commitments

As of March 31, 2021, the Company had non-cancelable purchase commitments to a third-party contract manufacturer for approximately $5.5 million and other vendors for approximately $4.0 million.

Litigation

From time to time, the Company is involved in certain legal actions arising in the ordinary course of business. In management’s opinion, based upon the advice of counsel, the outcome of such actions is not expected to have a material adverse effect on the Company’s future financial position or results of operations. As of March 31, 2021 and December 31, 2020 there are no material litigation matters.

Indemnification

From time to time, the Company enters into agreements in the ordinary course of business that include indemnification provisions. Generally, in these provisions the Company agrees to defend, indemnify, and hold harmless the indemnified parties for claims and losses suffered or incurred by such indemnified parties for which the Company is responsible under the applicable indemnification provisions. The terms of the indemnification provisions vary depending upon negotiations between the Company and its counterpart; however, typically, these indemnification obligations survive the term of the contract and the maximum potential amount of future payments the Company could be required to make pursuant to these provisions are uncapped. To date, the Company has never incurred costs to defend lawsuits or settle claims related to these indemnification provisions.

The Company has also entered into indemnity agreements pursuant to which it has indemnified its directors and officers, to the extent legally permissible, against all liabilities reasonably incurred in connection with any action in which such individual may be involved by reason of such individual being or having been a director or executive officer, other than liabilities arising from willful misconduct of the individual. To date, the Company has never incurred costs to defend lawsuits or settle claims related to these indemnity agreements. The unaudited condensed consolidated financial statements do not include a liability for any potential obligations under the indemnification agreements at March 31, 2021 and December 31, 2020.
