Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of the Business	ORGANIZATION AND DESCRIPTION OF THE BUSINESS Seer, Inc. (the Company) was incorporated in Delaware on March 16, 2017, and is headquartered in Redwood City, California. In December 2020, the Company formed the wholly-owned subsidiary, Seer Securities Corporation, located in Massachusetts. The Company is a life sciences company focused on capturing deep molecular insights from the proteome to enable novel insights and breakthroughs in the understanding of biology and disease. Since inception, the Company has devoted its efforts principally to research, development and commercialization of its technology and products, recruiting management and technical staff, acquiring operating assets, and raising capital. The Company is subject to a number of risks, similar to other early-stage life science companies, including, but not limited to, development and commercialization of its products, market acceptance of its products, development by its competitors of new technological innovations, protection of its intellectual property, and raising additional capital. Public Offering On February 1, 2021, the Company completed an underwritten public offering of 1,650,000 shares of its Class A common stock at a public offering price of $67.00 per share. The Company received net proceeds of $103.0 million after deducting offering costs, underwriting discounts, and commissions of $7.6 million. Liquidity As of March 31, 2022, the Company has incurred significant losses and has had negative cash flows from operations. As of March 31, 2022, the Company had cash, cash equivalents and investments of $471.8 million and an accumulated deficit of $150.2 million. Management expects to continue to incur significant expenses for the foreseeable future and to incur operating losses in the near term while the Company makes investments to support its anticipated growth. The Company believes that its cash and cash equivalents balance as of March 31, 2022 provides sufficient capital resources to continue its operations for at least 12 months from the issuance date of the accompanying unaudited condensed consolidated financial statements.

Summary of Significant Accounting Policies and Basis of Presentation

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The Company has issued shares of Class A common stock, herein referred to as “Class A common stock” or “Class A,” and Class B common stock, herein referred to as “Class B common stock” or “Class B,” and collectively as “common stock.” The unaudited condensed consolidated financial statements include the accounts of Seer, Inc. and its wholly-owned subsidiary. All intercompany transactions and balances have been eliminated.

The condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements of the Company at that date. Certain information and footnote disclosures typically included in the Company’s audited consolidated financial statements have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations, comprehensive loss and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated for any future annual or interim period.

The accompanying unaudited condensed consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2021 included in our Annual Report on Form 10-K filed with the SEC on March 1, 2022.

The Company has also made certain presentation changes to retroactively adjust for the effects of Accounting Standards Codification No. 842, Leases (“ASC 842”), the adoption of which was disclosed in our Annual Report on

Form 10-K filed on March 1, 2022, with an adoption effective date of January 1, 2021, using the modified retrospective method. The following table shows the affected line items within the unaudited condensed consolidated statements of cash flows (in thousands):


	Three Months Ended March 31, 2021
	As Previously Reported		Adjustments		As Adjusted

Cash flows from operating activities:
Non-cash operating lease expense	$	—	$	78	$	78
Deferred rent	(15)		15		—
Operating lease liabilities	—		(93)		(93)
Net cash used in operating activities	$	(14,872)	$	—	$	(14,872)

Supplemental disclosure of non-cash activities:
Lease liability obtained in exchange for right-of-use assets	$	—	$	7,823	$	7,823

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and assumptions, including, but not limited to, those related to the determination of stand-alone selling price for revenue recognition, the fair value of common stock, stock-based compensation, accrued research and development expenses, allowance for credit losses, inventory valuation, useful lives and valuation of property and equipment, income tax uncertainties, and tax valuation allowances.

Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from those estimates.

Impact of the COVID-19 Pandemic

As a result of the COVID-19 pandemic (COVID-19), the Company’s operations experienced disruptions and restrictions on employees’ ability to work and on the hiring of additional personnel, particularly as it relates to the Company’s phased commercial release. The Company’s personnel has experienced delays in accessing customers in certain countries with strict COVID-19 policies to provide installation and training services. Continued disruptions from COVID-19 could harm the Company’s operations and the Company cannot anticipate all the ways in which it could be adversely impacted by health epidemics such as COVID-19. The Company continues to monitor and assess the effects of the COVID-19 pandemic on its business, financial condition, results of operations and cash flows.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of March 31, 2022 and December 31, 2021, all amounts recorded as cash and cash equivalents consist of money market funds and are stated at fair value.

Restricted cash as of March 31, 2022 and December 31, 2021 represents cash held by a financial institution as security for a letter of credit issued to the lessor for one of the Company’s operating leases and is classified as noncurrent.

The following table provides a reconciliation of cash and cash equivalents, and restricted cash reported within the unaudited condensed consolidated balance sheets that sum to the total of the same amounts shown in the unaudited condensed consolidated statements of cash flows (in thousands):


	March 31,		December 31,
	2022		2021

Cash and cash equivalents	$	225,334	$	232,813
Restricted cash	524		524
Total cash and cash equivalents and restricted cash	$	225,858	$	233,337

Accounts Receivable, Net

Accounts receivable consist of amounts due from customers for the sales of products and services, net of any allowance for credit losses. The Company’s expected loss allowance methodology for receivables is developed using its historical collection experience, current and future economic market conditions and a review of the current aging status and financial condition of its customers. Specific allowance amounts are established to record the appropriate allowance for customers that have an identified risk of default. General allowance amounts are established based upon an assessment of expected credit losses for the Company’s receivables by aging category. Balances are written off when they are ultimately determined to be uncollectible. There was no allowance for credit losses related to accounts receivable as of March 31, 2022 and December 31, 2021.

As of March 31, 2022, there were two customers that represented 29% and 18% of the total accounts receivable balance, including related party receivables. As of December 31, 2021, there were three customers that represented 34%, 23%, and 19% of the total accounts receivable balance, including related party receivables.

Revenue Recognition

The Company generates revenue from sales of products and services. The Company’s product, the Proteograph Product Suite, consists of an instrument with embedded software essential to the instrument's functionality, and consumables as well as platform evaluation agreements. The Company began recognizing revenue from shipments of its Proteograph Product Suite during the second quarter of 2021. The service revenue primarily consists of revenue received from the generation and analysis of proteomic data on behalf of the customer and revenue is recognized upon delivery of the reports.

The Company recognizes revenue when control of the products and services is transferred to its customers in an amount that reflects the consideration it expects to be entitled to receive from its customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the transaction price, allocating the transaction price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is distinct within the context of the contract. The Company considers a performance obligation satisfied once it has transferred control of a good or service to the customer, meaning the customer has the ability to direct the use and obtain substantially all the economic benefits from the good or service.

In instances where right of payment or transfer of title is contingent upon the customer’s acceptance of the product, revenue is deferred until all acceptance criteria have been met. Revenue is recorded net of discounts and sales taxes collected on behalf of governmental authorities. Customers are invoiced generally upon shipment, or upon order for services, and payment is typically due within 30 or 60 days. Cash received from customers in advance of product shipment or providing services is recorded as a contract liability. The Company’s contracts with its customers generally do not include rights of return or a significant financing component.

The Company elected the practical expedient to account for shipping and handling activities that occur after the customer has obtained control as a fulfillment activity and not a separate performance obligation. The Company

expenses the incremental costs of obtaining a contract as and when incurred if the expected amortization period is one year or less or the amount is immaterial. The Company excludes from the transaction price all taxes assessed by a governmental authority on revenue-producing transactions that are collected by the Company from a customer.

The Company regularly enters into contracts that include various combinations of products and services, which are generally distinct and accounted for as separate performance obligations. The transaction price is allocated to each performance obligation in proportion to its standalone selling price. The Company determines the standalone selling price using average selling prices with consideration of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, the Company relies upon prices set by management, adjusted for applicable discounts.

Grant and Other Revenue

Grant revenue represents funding under cost reimbursement programs from federal foundation sources for qualified research and development activities performed by the Company and are not based on estimates that are subject to change. Grants received are assessed to determine if the agreement should be accounted for as an exchange transaction or a contribution. An agreement is accounted for as a contribution if the resource provider does not receive commensurate value in return for the assets transferred. Such amounts are recorded as revenue as grant-funded activities are performed up to the amount of expenses incurred. Any advance funding payments are recorded as deferred revenue until the activities are performed.

The Company recognizes revenue for research and development services contracts when control is transferred, which is upon completion of the services and when results of the services have been transferred to the customer. Upfront payments and fees received are recorded as deferred revenue until the Company performs its obligations under its arrangements. Amounts payable to the Company are recorded as other receivables when its right to consideration is unconditional.

Income Taxes

Beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminates the option to deduct research and development expenditures in the period incurred and requires amortization over five years or fifteen years pursuant to Internal Revenue Code Section 174. Although Congress is considering legislation that would defer the amortization requirement to later years, there is no assurance that the requirement to amortize will be repealed or otherwise modified. The Company is currently assessing the impact of this provision but does not expect it to have a material impact on its financial position, results of operations or cash flows in 2022.

Recently Adopted Accounting Pronouncements

In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (ASC Topic 832): Disclosures by Business Entities about Government Assistance. This standard requires annual disclosures that increase the transparency of transactions involving government grants, including the type of transactions, the accounting for those transactions and the effect of those transactions on an entity’s financial statements. The Company adopted this standard as of January 1, 2022, which did not have a material impact on its financial statements as of the adoption date.

FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS

The following tables set forth the fair value of the Company’s financial assets that were measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands).

Total assets measured at fair value		$	232,813	$	260,447	$	—	$	493,260

There were no financial liabilities measured at fair value. The Company classifies money market funds within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The Company classifies its investments in U.S. Treasury securities (Treasury bills, Treasury notes, and Treasury bonds) as Level 2 instruments and obtains fair value from an independent pricing service, which may use quoted market prices for identical or comparable instruments or model-driven valuations using observable market data or inputs corroborated by observable market data.

The carrying amount of the Company’s accounts receivable, other receivables, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate fair value due to their short maturities.

As of March 31, 2022 and December 31, 2021, unrealized losses on available-for-sale investments are not attributable to credit risk and are considered to be temporary. No investments have been in a continuous unrealized loss position for 12 months or longer. The Company believes it is more likely than not that investments in an

unrealized loss position will be held until maturity or the recovery of the cost basis of the investment. To date, the Company has not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value. As of March 31, 2022, $26.6 million of available-for-sale investments had remaining maturities between one and two years. The remainder of the available-for-sale investments have a remaining maturity of one year or less. As of March 31, 2022 and December 31, 2021, the Company recorded $0.5 million and $0.3 million of accrued interest, respectively, related to its available-for-sale investments as a component of other receivables on the condensed consolidated balance sheets.

COMMITMENTS AND CONTINGENCIES

Facility Lease Agreement

The Company leases office and laboratory space in Redwood City, California with a lease term that is set to end on September 30, 2032. The Company has an option to renew for an additional five-year term at then-current market rates, which is not reasonably certain of being exercised. The lease of additional office and laboratory space pursuant to an amendment entered into in June 2020 commenced in February 2022 and the Company recorded a right-of-use asset of $8.8 million and lease liability of $6.9 million as of the commencement of the lease. This lease liability is based on the present value of lease payments over the lease term, which was estimated using an incremental borrowing rate of 7.4% based on information available at the commencement date. In connection with the leased space, the Company maintains a letter of credit issued to the lessor in the amount of $0.5 million as of March 31, 2022 and December 31, 2021, respectively, which is secured by restricted cash that is classified as noncurrent at each date based on the term of the underlying lease.

During the period from June 2020 through May 2021, the Company was provided with temporary space. The Company was not required to pay additional rent for the temporary space, but was required to pay property taxes, insurance and normal maintenance costs with respect to the temporary space.

As of March 31, 2022, the remaining weighted-average lease term was 10.5 years and the weighted-average incremental borrowing rate used to determine the operating lease liabilities was 6.2%.

The components of lease costs related to the Company’s operating leases were as follows (in thousands):


	Three Months Ended March 31,
	2022		2021
Operating lease costs	$	813	$	185
Variable lease costs	194		133
Short-term lease costs	69		3
Total lease costs	$	1,076	$	321

Variable lease costs are primarily comprised of common area maintenance and include costs associated with the temporary space.

As of March 31, 2022, future minimum commitments under the Company’s non-cancelable facility operating lease are as follows:


Years ending December 31,	(in thousands)
2022 (remaining nine months)	$	2,005

Total undiscounted future minimum lease payments	42,316
Present value adjustment for minimum lease commitments	(11,836)
Tenant improvement receivable	(256)
Total operating lease liabilities	$	30,224

Purchase Commitments and Obligations

The Company has certain purchase commitments related to its inventory management with certain manufacturing suppliers wherein the Company is required to purchase the amounts forecasted in a blanket purchase order within a certain time period. The contractual obligations represent future cash commitments and liabilities under agreements with third parties and exclude orders for goods and services entered into in the normal course of business that are not enforceable or subject to change. These outstanding commitments amounted to $5.7 million and $5.5 million as of March 31, 2022 and December 31, 2021, respectively.

Guarantees and Indemnifications

In the normal course of business, the Company enters into agreements that contain a variety of representations and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future. The Company has entered into indemnification agreements with certain directors and officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of the status or service as directors or officers. To date, the

Company has not paid any claims or been required to defend any action related to its indemnification obligations. As of March 31, 2022 and December 31, 2021, the Company does not have any material indemnification claims that were probable or reasonably possible and consequently has not recorded related liabilities.

Contingencies

From time to time, the Company may become involved in legal proceedings arising in the ordinary course of business. The Company is not currently a party to any material legal proceedings.

Prognomiq, Inc.	3 Months Ended
Prognomiq, Inc.	Mar. 31, 2022
Business Combinations [Abstract]
Prognomiq, Inc.	PROGNOMIQ, INC. In August 2020, the Company formed a new entity, PrognomIQ, Inc. (PrognomIQ), and entered into a stock purchase agreement with PrognomIQ, pursuant to which the Company transferred to PrognomIQ certain assets that comprise the Company’s human diagnostics activities in exchange for all the outstanding equity interests of PrognomIQ. The Company subsequently completed a pro-rata distribution to its stockholders of most of the shares of capital stock of PrognomIQ. The Company has concluded that PrognomIQ is a VIE due to its reliance on future financing and insufficient equity investment at risk. However, the Company is not the primary beneficiary of the VIE as it does not have the power to direct the activities that most significantly impact the economic performance of PrognomIQ and does not have control over the PrognomIQ board of directors. The Company has determined that it has the ability to exercise significant influence over PrognomIQ and therefore has accounted for its investment in PrognomIQ using the equity method. PrognomIQ constitutes a related party and, as of March 31, 2022 and December 31, 2021, the Company recorded $1.1 million and $1.3 million in related party receivables, respectively, on the condensed consolidated balance sheets representing amounts due from product sales and services and for general transition services and support provided. Revenue received from PrognomIQ is recorded as related party revenue on the condensed consolidated statements of operations and comprehensive loss and is comprised of the sale of instruments and consumables, and services performed.

Summary of Significant Accounting Policies and Basis of Presentation (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The Company has issued shares of Class A common stock, herein referred to as “Class A common stock” or “Class A,” and Class B common stock, herein referred to as “Class B common stock” or “Class B,” and collectively as “common stock.” The unaudited condensed consolidated financial statements include the accounts of Seer, Inc. and its wholly-owned subsidiary. All intercompany transactions and balances have been eliminated. The condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements of the Company at that date. Certain information and footnote disclosures typically included in the Company’s audited consolidated financial statements have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations, comprehensive loss and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated for any future annual or interim period.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and assumptions, including, but not limited to, those related to the determination of stand-alone selling price for revenue recognition, the fair value of common stock, stock-based compensation, accrued research and development expenses, allowance for credit losses, inventory valuation, useful lives and valuation of property and equipment, income tax uncertainties, and tax valuation allowances. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from those estimates.
Cash, Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of March 31, 2022 and December 31, 2021, all amounts recorded as cash and cash equivalents consist of money market funds and are stated at fair value. Restricted cash as of March 31, 2022 and December 31, 2021 represents cash held by a financial institution as security for a letter of credit issued to the lessor for one of the Company’s operating leases and is classified as noncurrent.
Revenue Recognition	Revenue Recognition The Company generates revenue from sales of products and services. The Company’s product, the Proteograph Product Suite, consists of an instrument with embedded software essential to the instrument's functionality, and consumables as well as platform evaluation agreements. The Company began recognizing revenue from shipments of its Proteograph Product Suite during the second quarter of 2021. The service revenue primarily consists of revenue received from the generation and analysis of proteomic data on behalf of the customer and revenue is recognized upon delivery of the reports. The Company recognizes revenue when control of the products and services is transferred to its customers in an amount that reflects the consideration it expects to be entitled to receive from its customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the transaction price, allocating the transaction price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is distinct within the context of the contract. The Company considers a performance obligation satisfied once it has transferred control of a good or service to the customer, meaning the customer has the ability to direct the use and obtain substantially all the economic benefits from the good or service. In instances where right of payment or transfer of title is contingent upon the customer’s acceptance of the product, revenue is deferred until all acceptance criteria have been met. Revenue is recorded net of discounts and sales taxes collected on behalf of governmental authorities. Customers are invoiced generally upon shipment, or upon order for services, and payment is typically due within 30 or 60 days. Cash received from customers in advance of product shipment or providing services is recorded as a contract liability. The Company’s contracts with its customers generally do not include rights of return or a significant financing component. The Company elected the practical expedient to account for shipping and handling activities that occur after the customer has obtained control as a fulfillment activity and not a separate performance obligation. The Company expenses the incremental costs of obtaining a contract as and when incurred if the expected amortization period is one year or less or the amount is immaterial. The Company excludes from the transaction price all taxes assessed by a governmental authority on revenue-producing transactions that are collected by the Company from a customer. The Company regularly enters into contracts that include various combinations of products and services, which are generally distinct and accounted for as separate performance obligations. The transaction price is allocated to each performance obligation in proportion to its standalone selling price. The Company determines the standalone selling price using average selling prices with consideration of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, the Company relies upon prices set by management, adjusted for applicable discounts. Grant and Other Revenue Grant revenue represents funding under cost reimbursement programs from federal foundation sources for qualified research and development activities performed by the Company and are not based on estimates that are subject to change. Grants received are assessed to determine if the agreement should be accounted for as an exchange transaction or a contribution. An agreement is accounted for as a contribution if the resource provider does not receive commensurate value in return for the assets transferred. Such amounts are recorded as revenue as grant-funded activities are performed up to the amount of expenses incurred. Any advance funding payments are recorded as deferred revenue until the activities are performed. The Company recognizes revenue for research and development services contracts when control is transferred, which is upon completion of the services and when results of the services have been transferred to the customer. Upfront payments and fees received are recorded as deferred revenue until the Company performs its obligations under its arrangements. Amounts payable to the Company are recorded as other receivables when its right to consideration is unconditional.
Income Taxes	Income Taxes Beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminates the option to deduct research and development expenditures in the period incurred and requires amortization over five years or fifteen years pursuant to Internal Revenue Code Section 174. Although Congress is considering legislation that would defer the amortization requirement to later years, there is no assurance that the requirement to amortize will be repealed or otherwise modified. The Company is currently assessing the impact of this provision but does not expect it to have a material impact on its financial position, results of operations or cash flows in 2022.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (ASC Topic 832): Disclosures by Business Entities about Government Assistance. This standard requires annual disclosures that increase the transparency of transactions involving government grants, including the type of transactions, the accounting for those transactions and the effect of those transactions on an entity’s financial statements. The Company adopted this standard as of January 1, 2022, which did not have a material impact on its financial statements as of the adoption date.
