Share-Based Payment Arrangement [Abstract]

Equity Incentive Plan

8. Equity Incentive Plan

Equity Incentive Plans

As of March 31, 2023, 5,046,000 shares were reserved for future issuance under the 2020 Equity Incentive Plan (2020 Plan).

Employee Share Purchase Plan (ESPP)

As of March 31, 2023, 1,456,000 shares of common stock were reserved for issuance in connection with the current and future offering periods under the ESPP.

Restricted Stock

The Company issues restricted stock units (RSUs) and performance stock units (PSUs), both of which are considered restricted stock. The Company grants restricted stock pursuant to the 2020 Plan and satisfies such grants through the issuance of new shares. RSUs are share awards that, upon vesting, will deliver to the holder shares of our common stock.

RSUs with a service-based vesting condition granted to a grantee, beginning in February 2022, generally vest over a three-year period as follows either: (i) 25% on the first anniversary of the original vesting date, 25% quarterly over the course of the second year, and 50% quarterly over the course of the third year, or (ii) 33% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining two years. Prior to February 2022, RSUs with a service-based vesting condition granted to a grantee generally vest at a rate of 25% on the first anniversary of the original vesting date, with the balance vesting quarterly over the remaining three years.

In 2022, the Company issued a mix of 50% PSUs and 50% RSUs to its CEO, and a mix of 20% PSUs and 80% RSUs to its other executive officers and certain other senior leaders. These PSUs are earned and vest over performance and vesting periods extending through 2024 based on achievement against two metrics: (1) an operational metric tied to the number of patients treating at home on Tablo as of the end of 2023, with 50% of earned units vesting after certification of the achievement level following the end of 2023 and the remaining 50% of earned units vesting at the end of 2024 (performance-based vesting conditions, referred to as the 2022 Home PSUs) and (2) the Company's relative total stockholder return (relative TSR) over a two-year performance period as compared to companies in a pre-determined index of medical device companies, with 100% of earned units vesting at the end of 2024 (market-based vesting conditions, referred to as the 2022 Relative TSR PSUs). In 2023, the Company issued additional PSUs (2023 Home PSUs and 2023 Relative TSR PSUs) and RSUs to its CEO, other executive officers and certain other senior leaders under terms that are substantially the same except that the performance and vesting periods extending through 2025.

The 2023 target for the 2022 Home PSUs was approved by the Compensation Committee in early 2023. Therefore, the grant date and the fair value for these 2022 Home PSUs were established and the associated expense is being recognized over the remaining service period.

The 2024 target for the 2023 Home PSUs is expected to be determined and approved by the Compensation Committee in late 2023 or early 2024. Given such target has not yet been established, the grant date for these 2023 Home PSUs will only be established when the Compensation Committee approves and the Company communicates the target to the award recipients, which will then trigger the service inception date, the fair value of the awards, and the associated expense recognition period. Therefore, no expense is expected to be recognized for these 2023 Home PSUs until the grant date is established.

Income Tax Disclosure [Abstract]

Income Taxes

9. Income Taxes

For each of the three months ended March 31, 2023 and 2022, the Company incurred an income tax provision of an insignificant amount, which primarily related to foreign income taxes related to the Company’s Mexico operations. The U.S. federal and state net deferred tax assets have been fully offset by a valuation allowance, as the Company believes it is not more likely than not that the deferred tax assets will be realized.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Remaining Performance Obligations and Contract Liabilities

6. Commitments and Contingencies

Litigation

From time to time, the Company may become involved in legal proceedings or investigations, which could have an adverse impact on its reputation, business and financial condition and divert the attention of the Company’s management from the operation of the Company’s business. The Company is not presently a party to any legal proceedings that, if determined adversely to the Company, would individually or taken together have a material adverse effect on its business, results of operations, financial condition or cash flows.

Indemnification

In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with its partners, customers and suppliers. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of representations or covenants, intellectual property infringement or other claims made against such parties. These provisions may limit the time within which an indemnification claim can be made. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, the Company has not incurred any material costs as a result of such indemnification obligations and has not accrued any liabilities related to such obligations in these financial statements.

The maximum amount the Company is permitted to borrow under the SLR Credit Facilities is subject to certain overall borrowing limitations. The Company is permitted to borrow up to $200.0 million under the SLR Credit Facilities on the Closing Date. If the Company achieves a certain net revenue milestone, calculated on a trailing six-month basis (First Revenue Milestone), on or before June 30, 2024 and the Additional Tranche (as defined below) under the SLR Revolver has been approved, the Company will be permitted to borrow up to $250.0 million under the SLR Credit Facilities. If the Company achieves a subsequent additional net revenue milestone, calculated on a trailing six-month basis (Second Revenue Milestone), on or before June 30, 2025 and obtains lenders' credit approval, the Company will be permitted to borrow up to $300.0 million under the SLR Credit Facilities.

SLR Term Loan Facility

Pursuant to the terms and conditions of the SLR Loan Agreement, the Term Loan Lenders agreed to extend term loans to the Company in an aggregate principal amount of up to $250.0 million, comprised of (i) a term loan of $100.0 million (the Term A Loan), (ii) one or more term loans (in minimum increments of $20.0 million each) in the aggregate of up to $100.0 million (each, a Term B Loan) and (iii) one or more term loans in the aggregate of up to $50.0 million (each, a Term C Loan). Each Term A Loan, Term B Loan and Term C Loan is referred to single as a Term Loan and are referred to collectively as the Term Loans. The Term A Loan was funded on the Closing Date. The Term B Loan(s) are available for funding until August 22, 2024. The Term C Loan(s) are available subject to the lenders’ credit approval and the achievement of the Second Revenue Milestone on or before June 30, 2025. The Term C Loan will remain available for funding until one business day prior to November 1, 2027.

Any principal amount outstanding under the Term Loans will accrue interest at a rate per annum equal to one-month term Secured Overnight Financing Rate (term SOFR) (subject to a 2.75% floor), plus 5.15% (9.81% as of March 31, 2023), payable monthly in arrears. The Company is permitted to make interest-only payments on the Term Loans through November 30, 2026, which may be extended at the Company's option to May 31, 2027; provided that the Company meets the First Revenue Milestone. Any

principal amounts outstanding under the Term Loans, if not repaid sooner, are due and payable on November 1, 2027 (the Maturity Date). The Company is obligated to pay Agent (i) a non-refundable facility fee in the amount of $750,000 in respect of the Term A Loan, (ii) a non-refundable facility fee in the amount of $750,000 in respect of the Term B Loan(s), to be due and payable upon the earliest to occur of (a) the funding of the first Term B Loan, (b) December 20, 2023 and (c) the prepayment of the Term Loans and (iii) a non-refundable facility fee in the amount of $375,000 in respect of the Term C Loan, to be due and payable upon the earliest to occur of (a) the funding of the first Term C Loan, (b) one day prior to the Maturity Date and (c) the prepayment of the Term Loans. In addition, the Company is obligated to pay a final fee equal to 4.75% of the aggregate amount of the Term Loans funded, such final fee to be due and payable upon the earliest to occur of (i) the Maturity Date, (ii) the acceleration of the Term Loans and (iii) the prepayment of the Term Loans. The Company may voluntarily prepay the outstanding Term Loans, subject to a prepayment premium of (i) 3.0% of the principal amount of the Term Loan, if prepaid prior to or on the first anniversary of the Closing Date, (ii) 2.0% of the principal amount of the Term Loan, if prepaid after the first anniversary of the Closing Date through and including the second anniversary of the Closing Date, or (iii) 1.0% of the principal amount of the Term Loan if prepaid after the second anniversary of the Closing Date and prior to the Maturity Date.

SLR Revolver

The SLR Revolving Credit Agreement provides for an asset-based revolving credit facility with aggregate revolving commitments of $25.0 million (the Initial Revolver Commitment). The Company may request to increase the aggregate revolving commitments by $25.0 million (the Additional Tranche) to an aggregate amount of $50.0 million, subject to ABL Lender’s approval. Amounts available to be drawn under the SLR Revolver are equal to the lesser of (i) outstanding revolving commitments under the SLR Revolving Credit Agreement and (ii) a borrowing base (the Borrowing Base) equal to the sum of (a) 85% of eligible accounts receivable, plus (b) 25% of eligible inventory (not to exceed the lesser of 50% of the Borrowing Base and $5.0 million), minus (c) customary reserves, minus (d) unposted cash.

Any principal amount outstanding under the SLR Revolver will accrue interest at a rate per annum equal to one-month term SOFR (subject to a 2.75% floor), plus 3.20%, payable monthly in arrears. Interest on any borrowing is payable monthly. The Company is obligated to pay Lender (i) a non-refundable facility fee in the amount of $187,500 in respect of the Initial Revolver Commitment, (ii) a non-refundable facility fee in the amount of $187,500 in respect of the Additional Tranche, to be due and payable upon activation of the Additional Tranche, (iii) a commitment fee of 0.50% per annum of the average daily unused portion of the then commitment amount, payable monthly and (iv) a collateral monitoring fee of 0.10% per month of the average daily Borrowing Base during the prior month, payable monthly. The Company may terminate the SLR Revolver at any time, subject to a termination fee of (i) 2.0% of the aggregate revolving commitments then in effect, if terminated prior to or on the first anniversary of the Closing Date, (ii) 1.0% of the aggregate revolving commitments then in effect, if terminated after the first anniversary of the Closing Date through and including the second anniversary of the Closing Date, or (iii) 0.5% of the aggregate revolving commitments then in effect, if terminated after the second anniversary of the Closing Date through and including the third anniversary of the Closing Date. Such termination fee is waived if the SLR Revolver is terminated after the third anniversary of the Closing Date and prior to the Maturity Date.

Subject to customary exceptions and restrictions, the Company may borrow, repay and reborrow varying amounts under the SLR Revolver at any time. If at any time the outstanding amount under the SLR Revolver exceeds the lesser of (i) the aggregate revolving commitments then in effect and (ii) the Borrowing Base then in effect, the Company will be required to prepay outstanding amounts under the SLR Revolver.

The SLR Revolver shall expire on November 1, 2027.

Other Terms of the SLR Credit Facilities

As security for its obligations under the SLR Credit Facilities, the Company granted Agent, for the benefit of the Term Loan Lenders, and ABL Lender a continuing security interest in substantially all of the assets of the Company, including the Company’s intellectual property, subject to certain exceptions.

The SLR Credit Facility Agreements contain customary representations and warranties and customary affirmative and negative covenants, including, among others, requirements as to financial reporting and insurance and restrictions on the Company’s ability to dispose of its business or property, to change its line of business, to liquidate or dissolve, to enter into any change in control transaction, to merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, to incur additional indebtedness, to incur liens on its property or to pay any dividends or other distributions on capital stock, in each case with certain exceptions. The Company has also agreed to a financial covenant whereby, beginning with the fiscal quarter ending December 31, 2023, the Company must either (i) maintain certain levels of cash and cash equivalents in accounts subject to control agreements in favor of Agent and ABL Lender of at least 50% of the sum of (a) the outstanding obligations under the Term Loans (as defined below) and (b) the amount of the Company’s accounts payable that have not been paid within 120 days from the invoice date thereof or (ii) generate net product and product related revenue (or maintain gross profit margins) in excess of specified amounts (or percentages) for applicable measuring periods.

In addition, the SLR Credit Facility Agreements contain customary events of default that entitle Agent, under the SLR Loan Agreement, and ABL Lender, under the SLR Revolving Credit Agreement, to cause the Company’s indebtedness under the SLR Loan Agreement or SLR Revolving Credit Agreement, as applicable, to become immediately due and payable, and to exercise remedies against the Company and the collateral securing the obligations owed under the applicable SLR Credit Facility Agreement. Under the SLR Credit Facility Agreements, an event of default will occur if, among other things, the Company fails to make payments under either SLR Credit Facility Agreement, the Company breaches certain covenants under either SLR Credit Facility Agreement, subject to specified cure periods with respect to certain breaches, the Agent or ABL Lender, as applicable, determine that a material adverse change has occurred under the SLR Loan Agreement or SLR Revolving Credit Agreement, as applicable, or the Company or its assets become subject to certain legal proceedings, such as bankruptcy proceedings. Upon the occurrence and for the duration of an event of default, an additional default interest rate equal to 4.0% per annum will apply to all obligations owed under the SLR Credit Facility Agreements.

In November 2022, the Company borrowed $100.0 million under the Term A Loan on the Closing Date and incurred debt issuance costs of $3.8 million which were recorded as a direct deduction from the Term A Loan on the balance sheets and are being recognized as non-cash interest expense over the term of the loan using the effective interest method, along with the final payment fee. The facility fees of $0.9 million related to the Term B Loan and the Initial Revolver Commitment were recorded as deferred financing costs and are being recognized as non-cash interest expense over their respective commitment period using straight-line method.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2023
Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires an entity to utilize a new impairment model known as the current expected credit loss (CECL) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial assets and certain other instruments, including but not limited to available-for-sale debt securities. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company adopted ASU 2016-13 during the first quarter of fiscal year 2023. The adoption did not have a material impact on the Company's financial statements. Please see the description of the Company’s "Credit Losses” accounting policy in the “Significant Accounting Policies” section below.
Significant Accounting Policies	Significant Accounting Policies With the exception of the change from accounting for credit losses as a result of the adoption of ASU 2016-13, there have been no new or material changes to the Company’s significant accounting policies as described in its 2022 Annual Report that have had a material impact on the Company’s condensed financial statements and related notes.
Credit Losses	Credit Losses Accounts receivable. The allowance for doubtful accounts is based on the Company’s assessment of the Company’s best estimate of the amount of credit losses in customer accounts. The Company regularly reviews the allowance by considering factors such as existing contractual payment terms, historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. The allowance for doubtful accounts was not significant as of March 31, 2023 and December 31, 2022. Available-for-sale debt securities. The Company primarily holds U.S. government-sponsored enterprises debt securities, corporate debt securities, commercial paper, U.S. Treasury securities and money market funds. The Company regularly reviews the securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as historical experience, market data, financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government-sponsored enterprises debt securities. The basis for this assumption is that these securities have consistently high credit ratings by rating agencies, have a long history with no credit losses, are explicitly guaranteed by a sovereign entity, which can print its own currency, and are denominated in a currency that is routinely held by central banks, used in international commerce, and commonly viewed as a reserve currency. Additionally, all of the Company’s investments in corporate debt securities are in securities with high-quality credit ratings, which have historically experienced low rates of default. For the three months ended March 31, 2023 and 2022, the Company did not recognize credit loss related to available-for-sales debt securities.

- Definition

Disclosure of accounting policy for credit loss on financial instrument measured at amortized cost basis, net investment in lease, off-balance sheet credit exposure, and available-for-sale debt security. Includes, but is not limited to, methodology used to estimate allowance for credit loss, how writeoff of uncollectible amount is recognized, and determination of past due status and nonaccrual status.

The unrealized losses on the Company’s available-for-sale debt securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. As of March 31, 2023, the Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity. Additional factors considered in determining the treatment of unrealized losses include the financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which requires an entity to utilize a new impairment model known as the current expected credit loss (CECL) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial assets and certain other instruments, including but not limited to available-for-sale debt securities. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company adopted ASU 2016-13 during the first quarter of fiscal year 2023. The adoption did not have a material impact on the Company's financial statements. Please see the description of the Company’s "Credit Losses” accounting policy in the “Significant Accounting Policies” section below. Significant Accounting Policies With the exception of the change from accounting for credit losses as a result of the adoption of ASU 2016-13, there have been no new or material changes to the Company’s significant accounting policies as described in its 2022 Annual Report that have had a material impact on the Company’s condensed financial statements and related notes. Credit Losses Accounts receivable. The allowance for doubtful accounts is based on the Company’s assessment of the Company’s best estimate of the amount of credit losses in customer accounts. The Company regularly reviews the allowance by considering factors such as existing contractual payment terms, historical experience, credit quality, the age of the accounts receivable balances, and current economic conditions that may affect a customer’s ability to pay. The allowance for doubtful accounts was not significant as of March 31, 2023 and December 31, 2022. Available-for-sale debt securities. The Company primarily holds U.S. government-sponsored enterprises debt securities, corporate debt securities, commercial paper, U.S. Treasury securities and money market funds. The Company regularly reviews the securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as historical experience, market data, financial condition and near-term prospects of the investee, the extent of the loss related to the credit of the issuer, and the expected cash flows from the security. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government-sponsored enterprises debt securities. The basis for this assumption is that these securities have consistently high credit ratings by rating agencies, have a long history with no credit losses, are explicitly guaranteed by a sovereign entity, which can print its own currency, and are denominated in a currency that is routinely held by central banks, used in international commerce, and commonly viewed as a reserve currency. Additionally, all of the Company’s investments in corporate debt securities are in securities with high-quality credit ratings, which have historically experienced low rates of default. For the three months ended March 31, 2023 and 2022, the Company did not recognize credit loss related to available-for-sales debt securities.
