Basis of Presentation and Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2022

On June 1, 2021, the Company closed its initial public offering (“IPO”) in which it sold 11,730,000 shares of common stock (which included 1,530,000 shares that were sold pursuant to the full exercise of the IPO underwriters’ option to purchase additional shares) at a public offering price of $22.00 per share. The Company received net proceeds of approximately $237.2 million after deducting offering costs, underwriting discounts and commissions of $20.9 million.

Concurrent with the closing of the IPO:

•

38,826,388 outstanding shares of convertible preferred stock converted into an equivalent number of shares of common stock;

•

outstanding principal and interest amount of convertible promissory notes (the “2021 Convertible Notes”) converted into 7,531,777 shares of common stock; and

•

a warrant to purchase 129,156 shares of convertible preferred stock (the “SVB Warrant”) was automatically adjusted to become a warrant to purchase an equivalent number of shares of common stock.

Liquidity and Capital Resources

The Company has incurred net losses since inception and, as of March 31, 2022 and December 31, 2021, had an accumulated deficit of $173.9 million and $151.9 million, respectively. The Company has a limited operating history, and the revenue and income potential of the Company’s business are unproven. From incorporation in June 2016 through March 31, 2022, substantially all of the Company’s operations have been funded by the sales of equity securities and issuances of debt. As of March 31, 2022, the Company had cash, cash equivalents and short-term investments of $316.0 million. The Company believes that its cash, cash equivalents and short-term investments as of March 31, 2022 are sufficient to fund its operations for at least 12 months from the issuance date of the accompanying unaudited condensed financial statements.

Basis of Presentation and Use of Estimates

The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures required by GAAP for annual financial statements have been omitted. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for fair presentation, have been included. Interim financial results are not necessarily indicative of results anticipated for the full year.

The preparation of the Company’s unaudited condensed financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed financial statements and accompanying notes. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may significantly differ from these estimates and assumptions. For the year ended December 31, 2021, significant estimates and assumptions include the fair value of the 2021 Convertible Notes, the fair value of the liability for the SVB Warrant, the fair value of the Company’s preferred and common stock and stock-based compensation. After December 31, 2021, significant estimates and assumptions include stock-based compensation and the value of lease liabilities and right-of-use lease assets.

The Company determined there was no other-than-temporary impairment of any of its investments.

Inventory

Inventory includes raw materials, which are goods to be consumed directly or indirectly in production, work in process, which are goods in the course of production, and finished goods, which are goods awaiting sale. Inventory is recorded at the lower of cost or net realizable value. Costs are based on standard costs that are adjusted regularly to reflect current conditions so that at the balance-sheet date standard costs reasonably approximate costs under a first-in, first-out basis. Standard costs include acquisition and production costs. Raw materials include inventories that may be used in research and development activities, and such items are expensed as consumed or capitalized as property and equipment and depreciated.

Inventory in the prior year’s financial statements have been reclassified to conform to the current presentation on the condensed balance sheets and condensed statements of cash flows. No subtotals in the prior year financial statements were impacted as a result.

Leases

The Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC 842”), effective January 1, 2022. ASC 842 requires the Company to recognize on the balance sheet lease liabilities and corresponding right-of-use (“ROU”) lease assets for its operating leases where the Company is the lessee. The initial impact of the adoption is discussed below in the section titled “Recent Accounting Pronouncements—Adopted.”

The Company determines if an arrangement is or contains a lease at contract inception. Lease liabilities represent the Company’s obligation to make payments under its operating leases. ROU lease assets represent the Company’s right to use assets under its operating leases. The Company determines the value of lease liabilities and ROU lease assets on a lease-by-lease basis. A lease liability is recognized at the commencement date of an operating lease based on the present value of the future lease payments over the expected lease term. A corresponding ROU lease asset is recognized at the commencement date of an operating lease based on the value of the lease liability, adjusted for any lease incentives received, any initial direct costs incurred and any lease payments made at or before the lease commencement date. The Company made a policy election to not recognize lease liabilities and ROU lease assets for operating leases with an expected lease term of twelve months or less.

The Company calculates the present value of lease payments using the discount rate implicit in the lease, unless that rate cannot be readily determined. In that case, the Company uses its incremental borrowing rate based on information available at the date of lease commencement. The incremental borrowing rate is the estimated rate of interest that the Company would pay to borrow, on a collateralized basis, an amount equal to the lease payments over the expected lease term.

After lease commencement, the Company measures its operating leases as follows: (i) the lease liability based on the present value of the remaining lease payments using the incremental borrowing rate determined at lease commencement; and (ii) the ROU lease asset based on the remeasured lease liability, adjusted for any unamortized lease incentives received, any unamortized initial direct costs and the cumulative difference between lease expense and amounts paid under the lease. Lease expense is recognized on a straight-line basis over the expected lease term. Any lease incentives received and any initial direct costs are amortized on a straight-line basis over the expected lease term. Variable lease payments such as those related to property taxes, insurance and common area maintenance are recognized as expense when incurred.

Recent Accounting Pronouncements—Adopted

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (“ASU 2016-02”), codified as ASC 842. ASC 842 requires the Company to recognize on the balance sheet lease liabilities and corresponding ROU lease assets for its operating leases where the Company is the lessee. The Company adopted this standard effective January 1, 2021 using the modified retrospective method by applying the new standard to all leases existing as of January 1, 2022 and not restating any prior comparative periods. The Company elected the practical expedients to carry forward its historical lease classification, not reassess whether any expired or existing contracts are or contain leases and not reassess initial direct costs for existing leases. On January 1, 2022, the Company recorded operating lease liabilities of $7.1 million, ROU lease assets of $6.4 million, and derecognized deferred rent of $0.7 million. The additional disclosures required by the standard have been included in the section above titled “Leases” and in Note 9. Prior comparative periods have not been adjusted and continue to be reported under ASC 840.

Recent Accounting Pronouncements—Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. ASU 2016-13 is effective for the Company’s annual periods beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and related disclosures.
