PART I. FINANCIAL INFORMATION

Item 1. Financial Statements

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, as amended on July 12, 2021. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with US 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,September 30, 2021, the Company had an accumulated deficit of approximately $230$275.0 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,September 30, 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 1-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 1-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 1 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 1 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 1 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”).US 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.

PIPE Investment

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

Note 2 – Summary of Significant Accounting Policies

Based on our public float as of EstimatesJune 30, 2021, we expect to become a large accelerated filer, and lose emerging growth company status, as of December 31, 2021. As of December 31, 2021, we will be required to adopt new or revised accounting standards when they are applicable to public companies that are not emerging growth companies.

The preparationIn 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 financial statements in conformity with US GAAP requires managementcurrent expected credit losses (“ECL”). Under the new model, an entity is required to make estimates and assumptions that affectestimate ECL on available-for-sale (AFS) debt securities only when the reported amounts of assets and liabilities atfair value is below the dateamortized cost of the financial statementsasset 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)is no longer based on an impairment being “other-than-temporary”. The Company bases its estimatesnew model also requires the impairment calculation on historical experiencean individual security level and on various other assumptions thatrequires an entity to use the Company believespresent value of cash flows when estimating the ECL. The credit-related losses are required to be reasonable under the circumstances. On an ongoing basis, the Company evaluates these assumptions, judgmentsrecognized through earnings and estimates. Actual results may differ from these estimates.

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. The Company increaseswill adopt ASC 2018-15 for the longerDecember 31, 2021 annual period. The Company does not believe the virus impactsadoption of this new guidance will have a material impact on its consolidated financial statements.

There have been no other newly issued or newly applicable accounting pronouncements that do not includerequire adoption until a future date that have had, or are expected to have, a significant financing component because the primary purpose is not to receive financing from the customers.

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:
