Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and accompanying notes and other financial information included elsewhere in this Annual Report on Form 10-K. In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. You should review the sections titled “Note Regarding Forward-Looking Statements” for a discussion of forward-looking statements and in Part I, Item 1A, “Risk Factors” for a discussion of factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and elsewhere in this Annual Report on Form 10-K.

Overview

We develop and market advanced cancer genomic tests and analytics. Our tests and analytics are used by pharmaceutical companies for translational research, biomarker discovery, the development of personalized cancer therapies, and we expect in the near future, for clinical trial enrollment. Our advanced tests are used by physicians to detect cancer recurrence, monitor cancer evolution, and uncover insights for therapy selection. We also provide sequencing and data analysis services to support population sequencing initiatives.

Today, our products are routinely used by many of the largest oncology-focused pharmaceutical companies for analysis of patient samples in their clinical trials and drug development programs. Our advanced genomic sequencing and analytics also support the development of personalized cancer vaccines and other next-generation cancer immunotherapies. For example, we are providing genomic testing to Moderna, Inc. ("Moderna") in its ongoing clinical trials evaluating a personalized cancer vaccine. In addition, we partner with diagnostics companies by providing our advanced tumor profiling and analysis capabilities as an input to their products. More recently, we launched new diagnostic offerings for the clinical setting and, in November 2023, entered into an agreement with Tempus AI, Inc. (formerly known as Tempus Labs, Inc., and referred to herein as "Tempus") to commercialize NeXT Personal Dx in the clinical diagnostics market. Finally, we have also pursued non-cancer related business opportunities, specifically within the population sequencing market, by providing whole genome sequencing ("WGS") services under contract with the U.S. Department of Veterans Affairs Million Veteran Program ("VA MVP").

As part of one of our new strategies for 2023 and beyond, we are working with a growing number of leading cancer centers and world-class academic research institutions to build and publish the clinical evidence-base to support our products and our key indications, as well as to obtain reimbursement coverage from Medicare and other payors. Because of the ultra-high analytical sensitivity of our technology, we are initially focusing on three indications: breast cancer, lung cancer, and immunotherapy (IO) monitoring. We have collaborations with Cancer Research UK, University College London, and the Francis Crick Institute (the TRACERx study); The Royal Marsden; the Vall d'Hebron Institute of Oncology (VHIO); Duke University; the Dana-Farber Cancer Institute; University Medical Center Hamburg-Eppendorf (also known as UKE); and Criterium and the Academic Breast Cancer Consortium that will focus on building the evidence-base for our technology and these indications. If the key opinion leaders ("KOLs") we are collaborating with have a positive experience using our products, we are optimistic this will support broader use of our products by other KOLs, as well as clinicians in the future.

Our work in oncology is underpinned by our experience and capacity for next-generation sequencing at scale. We have the capacity to sequence and analyze over 300 trillion bases of DNA per week in our facility. We believe that our capacity is already larger than most cancer genomics companies, and we continue to build automation and other infrastructure to scale further as demand increases. To date, we have sequenced more than 385,000 human samples, of which more than 175,000 were whole human genomes.

2023 Highlights

Total revenue increased 13%, or $8.4 million, during 2023 compared to 2022, primarily driven by higher revenue from enterprise sales and pharma tests. Revenue from enterprise sales was $31.7 million in 2023 compared to $26.6 million in 2022, an increase of 19%. Revenue from pharma tests was $31.9 million in 2023 compared to $29.6 million in 2022, an increase of 8%.

Key business accomplishments and financial updates in 2023 and early 2024 include:

•

Received Medicare coverage for NeXT Dx.

•

Amended Natera agreement to extend volume commitments through the end of 2024.

•

Signed key partnership agreement with Tempus to commercialize NeXT Personal Dx in clinics or with oncologists.

•

Factors Affecting Our Performance

We believe there are several important factors that we expect to impact our operating performance and results of operations, including:

•

The continued development of the market for genomic-based tests. Our performance depends on the willingness of pharmaceutical companies, enterprise customers, and oncologists to continue to seek more comprehensive molecular information to develop more efficacious cancer therapies.

•

Increasing adoption of our products and solutions by existing customers. Our performance depends on our ability to retain and broaden adoption with existing customers. Because our technology is novel, some customers begin using our products by initiating pilot studies involving a small number of samples to gain experience with our service. As a result, historically a significant portion of our revenue has come from existing customers. We believe that our ability to convert initial pilots into larger orders from existing customers has the potential to drive substantial long-term revenue. We expect there may be some variation in the number of samples they choose to test each quarter.

•

Adoption of our products and solutions by new customers. While new customers initially may not account for significant revenue, we believe that they have the potential to grow substantially over the long term as they gain confidence in our service. Our ability to engage new customers is critical to our long-term success. Our publications, posters and presentations at scientific conferences lead to engagement at the scientific level with potential customers who often make the initial decision to gain experience with our products. Accessing these new customers through scientific engagement and marketing to gain initial buy-in is critical to our success and gives us the opportunity to demonstrate the utility of our products.

•

Our revenue and cost are affected by the volume of samples we receive from customers from period to period. The timing and size of sample shipments received after orders have been placed is variable. Since sample shipments can be large, and are often received from a third party, the timing of arrival can be difficult to predict over the short term. Although our long-term performance is not affected, we see quarter-to-quarter volatility due to these factors. Samples arriving later than expected may not be processed in the quarter proposed and result in revenue the following quarter. Since many of our customers request defined turnaround times, we employ project managers to coordinate and manage the complex process from sample receipt to sequencing and delivery of results.

•

Investment in product innovation to support growth. Investment in research and development, including the development of new products and capabilities is critical to establish and maintain our leading position. We have invested significantly in our NeXT platform, introducing new products and additional capabilities. We are also collaborating with KOLs to support the clinical utility of our products. We believe this work is critical to gaining customer adoption and expect our investments in these efforts to continue.

•

Leverage our operational infrastructure. We have invested significantly in our sample processing capabilities and commercial infrastructure. With our current operating model and infrastructure, we can increase our production and commercialize new generations of our products. We expect to grow our revenue and spread our costs over a larger volume of services.

Components of Operating Results

Revenue

We derive our revenue from sales of advanced sequencing and analytics to the following four customer types:

•

Pharma tests and services includes sales of testing services and data analytics for clinical trials and research to pharmaceutical companies in support of their drug development programs.

•

Enterprise sales includes sales of tumor profiling and diagnostic tests directly to another business as an input to their products. Revenue from our partnership with Natera to provide advanced tumor analysis for use in Natera's MRD test currently makes up substantially all of the revenue in this category.

•

Population sequencing includes sales of genomic sequencing services and data analytics to support large-scale genetic research programs. All of the revenue in this category is from our partnership with the VA MVP.

•

Other includes sales of genomic tests and analytics to universities and non-profits. This category also includes sales of diagnostics tests ordered by healthcare providers for cancer patients, which was insignificant for periods presented.

Our ability to increase revenue will depend on our ability to further increase sales to these groups of customers, expand our customer base within each group, and expand our business in the clinical diagnostics market. To do this, we are developing a growing set of state-of-the-art services and products; advancing our operational infrastructure; building our regulatory credentials; focusing our marketing efforts on large pharmaceutical companies; building and publishing the clinical evidence-base to support our products and our key indications, as well as to obtain reimbursement coverage from Medicare and other payors; and seeking additional partnerships such

as ours with Natera. We sell through a small direct sales force. In late 2023, we entered into an agreement with Tempus to commercialize NeXT Personal Dx in the clinical diagnostics market and will be leveraging Tempus' significantly larger sales force.

We have one reportable segment from the sale of sequencing and data analysis services. Most of our revenue to date has been derived from sales in the United States.

Costs and Expenses

Cost of Revenue

Cost of revenue consists of raw materials costs, personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and benefits), laboratory supplies and consumables, depreciation and maintenance on equipment, and allocated facilities and information technology (“IT”) costs. We expect variability in our gross margins over the medium-term due to fluctuations in customer mix and volume, investments in newer sequencing platforms and new capabilities such as automation of laboratory workflows, processing of diagnostic tests for the clinical market while we work to secure reimbursement, and costs related to our new Fremont facility. Over the long-term, we anticipate higher gross margins as growing revenue leads to economies of scale.

Research and Development Expenses

Research and development expenses consist of costs incurred for the research and development of our services and products and costs related to conducting studies and collaborations with partners to validate the clinical utility of our offerings. The expenses primarily consist of personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and benefits); laboratory supplies and consumables; costs of processing samples for research, product development, collaborations and studies; depreciation and maintenance on equipment; and allocated facilities and IT costs. We include in research and development expenses the costs to further develop software we use to operate our laboratory, analyze the data it generates, and automate our operations.

We expense our research and development costs in the period in which they are incurred. We expect research and development expenses to decrease as a result of our reductions in workforce initiated in 2023 and our closure of operations in China.

Selling, General and Administrative Expenses

Selling expenses consist of personnel costs (salaries, commissions, bonuses, stock-based compensation, payroll taxes, and benefits), customer support expenses, direct marketing expenses, and market research. Our general and administrative expenses include costs for our executive, accounting, finance, legal, and human resources functions. These expenses consist of personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and benefits), corporate insurance, audit and legal expenses, consulting costs, and allocated facilities and IT costs. We expense all selling, general and administrative costs as incurred.

Selling, general and administrative expenses have decreased significantly since the completion of our first quarter 2023 reduction in workforce. We expect expenses to remain around this lower level over the next couple of years.

Lease Impairment

We recognized an impairment loss for operating lease right-of-use assets as a result of the change in use of our Menlo Park facility during the third quarter of 2023.

Restructuring and Other Charges

Restructuring and other charges consists of charges in connection with our two reductions in workforce initiated in 2023 and charges in connection with the closure of our China operations.

Interest Income and Interest Expense

Interest income consists primarily of interest earned on our cash and cash equivalents and short-term investments. Interest expense is the recognition of imputed interest on noninterest bearing loans.

Other Income (Expense), Net

Other income (expense), net consists primarily of charges related to the issuance and remeasurement of warrants to Tempus during the year ended December 31, 2023. Otherwise, other income (expense), net consists primarily of foreign currency exchange gains and losses.

Pharma tests and services

Revenue from pharma tests and services increased 8%, or $2.4 million, in 2023. Growth from new customers drove the revenue increase. Notably, three customers that were either new in 2023 or 2022, accounted for an increase of $3.8 million in revenue as these customers selected our advanced genomic tests for their clinical trials and research projects. Additionally, revenue from one of our customers developing personalized cancer therapies increased by $2.3 million. Those increases were partially offset by decreases in revenue from multiple customers due to non-recurring projects and variability in timing and spending levels on clinical trial projects in general.

Enterprise sales

Revenue from enterprise sales increased 19%, or $5.1 million, in 2023. This was due to an increase in the volume of samples we tested for Natera, partially offset by lower selling prices. The number of samples we processed for Natera increased by over 55% in 2023.

We amended our agreement with Natera during the fourth quarter of 2023 to extend minimum volume commitments through the end of 2024. Previously, Natera's volume commitments extended only through the first quarter of 2024. In addition, we plan to introduce a lower-cost version of our exome product offering for Natera in the first half of 2024 in order to support their price requirements, and we expect our total revenue from Natera in 2024 to decline, due to the lower prices.

Population sequencing

Population sequencing revenue is made up entirely of sales to the VA MVP. The increase in revenue was driven by an increase in samples we tested, which offset a nearly 50% reduction in selling prices in 2023 as compared to 2022.

Revenue recognized each period is also impacted by timing of our fulfillment of samples under each annual task order. Our annual task orders received in 2023, 2022, and 2021 were $7.5 million, $10.0 million, and $9.7 million, respectively. Our contract with the VA MVP does not include specific testing turnaround times. Therefore, we have the ability to modulate the volume of samples processed from the VA MVP up or down to complement sample volumes from other customers, which can vary from period to period. As of the end of 2023, our remaining unfulfilled task orders amounted to $7.4 million, which we expect to recognize as revenue within the next 12 months.

Cost of revenue

The increase in cost of revenue of 7%, or $3.6 million, was primarily due to higher revenue levels (revenue increased 13% over the same period), partially offset by dedication of more laboratory resources to support sample processing required for clinical evidence generation, which is a non-revenue generating activity and thus reported as R&D expense. Specific components of the increase were a $4.9 million increase in direct material costs due to higher revenue levels, a $2.0 million increase in facilities and equipment costs (partly due to movement of our laboratory from our prior Menlo Park facility to the new Fremont facility), and a $2.0 million increase in laboratory supplies and consumables (enterprise customer orders require more supplies to process as compared to other customer categories); partially offset by a $5.3 million decrease in shared laboratory costs due to greater usage of our laboratory capacity for R&D activities.

Table of Contents

Research and development

Research and development expenses remained flat in 2023 as compared to 2022. Increases in costs associated with clinical evidence generation and collaborations, and increases in facility costs (as a result of the R&D function moving into our Fremont facility during 2023), were offset by cost savings from our reductions in workforce initiated in 2023.

Specific offsetting components of research and development expense include a $5.0 million increase in sample processing costs incurred in our laboratory for product development, collaborations, and clinical evidence generation, and a $2.2 million increase in facilities costs; offset by a $7.3 million decrease in personnel-related costs driven by our reductions in workforce.

Selling, general and administrative

The decrease in selling, general and administrative expenses of 22%, or $14.2 million was primarily due to cost savings from our reductions in workforce initiated in 2023.

Specific components of the decrease were a $11.7 million decrease in personnel-related costs driven by our reductions in workforce, a $5.1 million decrease in facilities costs as a result of the R&D function and additional lab teams moving into our Fremont facility and consequently receiving a share of such facility costs that were previously allocated to SG&A, and a $1.5 million decrease in professional services; partially offset by a $2.9 million increase in depreciation of office-related fixtures and furniture (driven by our Fremont headquarters), a $1.0 million increase in software and subscriptions costs, and a $0.2 million increase in marketing costs such as trade shows expenses.

Lease impairment

During the third quarter of 2023, we completed the move of our laboratory operations from our Menlo Park facility to our Fremont facility and began actively marketing the Menlo Park space for sublease. Accordingly, we evaluated the ongoing value of the operating lease right-of-use asset associated with the Menlo Park facility. Based on this evaluation, we determined that the right-of-use asset with a carrying amount of $6.7 million was no longer recoverable and was impaired and wrote it down to its estimated fair value of $1.1 million, which resulted in a noncash impairment loss of $5.6 million. Estimated fair value was based on expected future sublease cash flows (with the assistance of a third-party real estate broker), net of brokerage commissions and estimated tenant incentives, discounted at a market rate of return on similar assets. The estimation of fair value also included expected downtime prior to the commencement of a future sublease.

Restructuring and other charges

During 2023, we initiated two rounds of workforce reductions to reduce our cash burn and increase operating efficiencies. Combined, our headcount was reduced by almost 50% from 2022 levels. We also closed our China operations.

The $8.1 million in restructuring and other charges recognized in 2023 is comprised of $7.5 million in one-time employee termination benefits (including costs related to termination of our former China employees) and $0.6 million of other noncash charges (primarily asset disposals and impairments in connection with the closure of our China operations).

Interest income and interest expense

The increase in interest income was due to increased yields on our investments. Interest expense is the recognition of imputed interest on noninterest bearing loans.

Other income (expense), net

In connection with our November 2023 agreement with Tempus, we issued two warrants to purchase, in the aggregate, up to 9,218,800 shares of our common stock. If Tempus acquires any shares of common stock directly from us other than by exercising the warrants, then the total number of shares issuable upon exercise of the warrants will be reduced by such shares. Because the number of shares issuable upon settlement are subject to adjustment, the warrants are classified as liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as other income (expense). Additionally, since the initial fair value of the warrants of $6.9 million exceeded the total proceeds received from Tempus of $6 million, a loss of $0.9 million was immediately recognized within other income (expense).

Table of Contents

Fair value of the warrants increased by $3.1 million as of December 31, 2023. The increase in fair value, plus the immediate loss of $0.9 million recognized upon issuance, resulted in a $4.0 million expense recognized in other income (expense), net during the year ended December 31, 2023.

During 2022 and 2021, other income (expense), net consisted mainly of foreign currency remeasurements.

Liquidity and Capital Resources

The following table presents selected financial information (in thousands):

December 31,

From our inception through December 31, 2023, we have funded our operations primarily from $279.0 million in net proceeds from our follow-on equity offerings in August 2020 and January 2021, $144.0 million in net proceeds from our IPO in June 2019, $89.6 million from issuance of redeemable convertible preferred stock, $3.5 million in net proceeds from our ATM facility (see Note 2, Summary of Significant Accounting Policies), as well as cash from operations and debt financings. As of December 31, 2023, we had cash and cash equivalents of $57.0 million and short-term investments of $57.2 million.

We have incurred net losses since our inception. We anticipate that our current cash and cash equivalents and short-term investments, together with cash provided by operating activities, are sufficient to fund our near-term capital and operating needs for at least the next 12 months.

We have based these future funding requirements on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. If our available cash balances and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, including because of lower demand for our services or other risks described in this Annual Report on Form 10-K, we may seek to sell additional common or preferred equity or convertible debt securities, enter into an additional credit facility or another form of third-party funding or seek other debt financing. We filed a sales agreement prospectus in December 2023 pursuant to which we may offer and sell up to $50.0 million of shares of our common stock through our ATM facility. The sale of equity and convertible debt securities may result in dilution to our stockholders and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. The terms of debt securities issued or borrowings pursuant to a credit agreement could impose significant restrictions on our operations. Additional capital may not be available on reasonable terms, or at all.

Our short-term investments portfolio is primarily invested in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. Our investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer.

As of December 31, 2023, cash and cash equivalents held by foreign subsidiaries was $1.2 million, most of which was held by our China subsidiary. During the first half of 2023, we closed our China operations and, in February 2024, we completed the dissolution of the China entity and repatriated all cash that was held at the entity back to our headquarters.

Cash Flows

Year Ended December 31,

The $14.0 million decrease in cash used in operating activities during 2023 as compared to 2022 was primarily due to lower spend on operating expenses (particularly lower payroll expenses after our reductions in workforce initiated in 2023), higher customer deposits received (mostly in connection with our agreement with Moderna to support its ongoing clinical trials evaluating a personalized cancer vaccine), and efficient management of working capital; partially offset by lower landlord contributions received during 2023 versus 2022 in connection with our Fremont facility build-out.

The $39.4 million decrease in cash provided by investing activities during 2023 as compared to 2022 was due to significantly lower net proceeds from short-term investment maturities, partially offset by a $39.0 million reduction in capital expenditures.

The $9.7 million increase in cash provided by financing activities during 2023 as compared to 2022 was driven by $6 million in proceeds from issuance of warrants to Tempus and $3.5 million in net proceeds from sales of common stock under our ATM facility, both of which did not occur during 2022.

Table of Contents

Material Cash Requirements

Our material cash requirements in the short- and long-term consist primarily of variable costs of revenue, operating expenditures, capital expenditures, property leases, and other. We plan to fund our material cash requirements with our existing cash and cash equivalents and short-term investments, which amounted to $114.2 million as of December 31, 2023, as well as anticipated cash receipts from customers. To fund our material cash requirements in the short- and long-term, we may also seek to sell additional common or preferred equity or convertible debt securities, enter into an additional credit facility or another form of third-party funding or seek other debt financing.

Variable costs of revenue. From time to time in the ordinary course of business, we enter into agreements with vendors for the purchase of raw materials, laboratory supplies and consumables to be used in the sequencing of customer samples. However, we generally do not have binding and enforceable purchase orders beyond the short term, and the timing and magnitude of purchase orders beyond such period is difficult to accurately project. We currently expect spending in this area to increase in 2024 relative to 2023 to support expected higher levels of revenue.

Operating expenditures. Our primary use of cash relates to employee compensation, spend on professional services, spend related to research and development projects, and other costs related to our research and development, selling, general and administrative functions. We currently expect to decrease our spend in these areas as a result of our workforce reductions initiated in 2023. On a long-term basis, we manage future cash requirements relative to our long-term business plans.

Capital expenditures. Capital expenditures are expected to decrease from 2023 levels as we have completed significant laboratory capacity additions. Going forward, our capital expenditures are expected to consist primarily of laboratory equipment and computer equipment. We currently expect capital expenditures to be approximately $1 million in 2024 and between $4 million to $6 million in each of the years 2025 and 2026.

Property leases. Our noncancelable operating lease payments were $78.6 million as of December 31, 2023. The timing of these future payments, by year, can be found in Part II, Item 8 of this Form 10-K in the Notes to Consolidated Financial Statements in Note 7, “Leases.”

Other. As of December 31, 2023, we have an outstanding noninterest bearing loan that was used to finance the purchase of equipment for our laboratory. We owe a total of $2.5 million, with half of that amount owed in 2024 and the other half in 2025. Additionally, we had an outstanding noninterest bearing loan that was used to finance the purchase of internal use software licenses and related ongoing support. We will make a payment of $0.4 million in September 2024 to pay off this loan. Further discussion of this loan can be found in Part II, Item 8 of this Form 10-K in the Notes to Consolidated Financial Statements in Note 6, “Loans.”

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably possible could materially impact the financial statements. We believe that the assumptions and estimates associated with revenue recognition, leases, and common stock warrants have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

Revenue Recognition

We generate our revenue from selling sequencing and data analysis services. We agree to provide services to our customers through a contract, which may be in the form of a combination of a signed agreement, statement of work and/or a purchase order.

We have evaluated the performance obligations contained in contracts with customers to determine whether any of the performance obligations are distinct, such that the customers can benefit from the obligations on their own, and whether the obligations can be separately identifiable from other obligations in the contract. For the significant majority of our contracts to date, the customer orders a specified quantity of a sequencing; therefore, the delivery of the ordered quantity per the purchase order is accounted for as one performance obligation. Our contracts include only one performance obligation—the delivery of the sequencing and data analysis services to the customer.

Fees for our sequencing and data analysis services are predominantly based on a fixed price per sample. The fixed prices identified in the arrangements only change if a pricing amendment is agreed with a customer. In limited cases we provide our customers a discount if samples received above a certain volume are purchased. In such cases, the discount applies prospectively. We have analyzed such discounts if they represent a material right provided to a customer. We have concluded that such discounts generally do not represent a material right provided to a customer since they are not deemed to be incremental to the pricing offered to the customer or are not enforceable options to acquire additional goods. As a result, these discounts do not constitute a material right and do not meet the definition of a separate performance obligation, except in limited instances. We do not offer retrospective discounts or rebates.

Table of Contents

Accordingly, all of the transaction price, net of any discounts, is allocated to one performance obligation. Therefore, upon delivery of the services, there are no remaining performance obligations.

Leases

Lease liabilities are recognized at the present value of the fixed lease payments, reduced by landlord incentives, using a discount rate based on our current borrowing rate at the lease commencement date (the incremental borrowing rate), unless the rate implicit in the lease is readily determinable.

In August 2021, we entered into a 13.5-year lease for our new corporate headquarters in Fremont, California. We estimated our incremental borrowing rate as the rate implicit in the lease was not readily determinable. To determine the incremental borrowing rate, we estimated our credit rating by comparing certain financial ratios and metrics of the Company to those of other issuers with publicly-available credit ratings from Standard & Poor’s (S&P). We then adjusted yields from publicly traded corporate bonds of companies of similar size and credit rating over a term approximating the term of our lease for the nature of the collateral. Our concluded incremental borrowing rate for this lease was 5.8%, which resulted in a lease liability and right-of-use asset of $44.7 million.

In September 2022, the lease commencement date for our new facility in Fremont, California was delayed from the original intended date due to delays in the completion of the work necessary for us to move into the facility, which resulted in a reassessment of the lease term and consequently a remeasurement of the lease liability and corresponding adjustment to the carrying amount of the right-of-use asset based on an updated incremental borrowing rate. We estimated our incremental borrowing rate by using the same method described above and concluded that the incremental borrowing rate for the remeasured lease was 10.5%. The lease reassessment resulted in a $12.9 million reduction to right-of-use assets in 2022. The increase in our estimated borrowing rate between August 2021 and September 2022 mostly reflects the higher interest rate environment in 2022 as compared to 2021.

Common Stock Warrants

In November 2023, we entered into an agreement with Tempus to commercialize NeXT Personal Dx in the clinical diagnostics market. In connection with this agreement, we issued to Tempus two warrants to purchase, in the aggregate, up to 9,218,800 shares of our common stock. If Tempus acquires any shares of common stock directly from us other than by exercising the warrants, then the total number of shares issuable upon exercise of the warrants will be reduced by such shares. Because the number of shares issuable upon settlement are subject to adjustment, the warrants are classified as liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as other income (expense).

The Black-Scholes option-pricing model was used to estimate fair value of the warrants issued to Tempus at the date of issuance, November 28, 2023, and at each subsequent balance sheet date. Estimating fair value using the Black-Scholes option-pricing model requires a number of assumptions. Changes in the assumptions can materially affect the fair value and ultimately how much other income (or expense) is recognized. The inputs generally require analysis to develop.

•

Expected Term—The expected term assumption represents the contractual period of each of the two warrants.

•

Expected Volatility—Expected volatility was based on the Company's actual historical volatility over the expected terms of the warrants.

•

Expected Dividend Yield—The Black-Scholes option-pricing valuation model calls for a single expected dividend yield as an input. We currently have no history or expectation of paying cash dividends on our common stock.

•

Risk-Free Interest Rate—The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the warrants.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Company and Nature of Business

Personalis, Inc. (the "Company" or "Personalis") develops and markets advanced genomic tests and analytics for precision oncology and personalized testing. The Company also provides sequencing and data analysis services to support population sequencing initiatives. Genomic tests are sold primarily to pharmaceutical companies, biopharmaceutical companies, diagnostics companies, universities, non-profits, and government entities, while services for population sequencing initiatives are sold primarily to government entities. The principal markets for the Company’s services are in the United States and Europe.

The Company is expanding its business model to offer genomic tests directly to cancer patients in a clinical setting. However, revenue generated from clinical customers was not significant for any periods presented in these consolidated financial statements.

The Company was incorporated in Delaware in February 2011 and began operations in September 2011. The Company formed a wholly owned subsidiary, Personalis (UK) Ltd., in August 2013 and a wholly owned subsidiary, Shanghai Personalis Biotechnology Co., Ltd., which is referred to as “Personalis (Shanghai) Ltd” herein, in October 2020. During the first half of 2023, the Company terminated its operations in China and the Company completed the process of dissolving the Personalis (Shanghai) Ltd entity in February 2024. Refer to Note 9 for further information. The Company operates and manages its business as one reportable operating segment, which is the sale of sequencing and data analysis services.

The Company has incurred losses to date and expects to incur additional losses for the foreseeable future. The Company continues to invest the majority of its resources in the development and growth of its business, including investments in product development and studies to prove the clinical validity and utility of the Company's tests. The Company’s activities have been financed to date primarily through the sale of its equity securities and cash from operations.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding annual reporting. The consolidated financial statements include the accounts of Personalis, Inc. and its wholly owned subsidiaries, Personalis (UK) Ltd. and Personalis (Shanghai) Ltd. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The estimates include, but are not limited to, revenue recognition, useful lives assigned to long-lived assets, discount rates for lease accounting, the valuation of stock options, the valuation of common stock warrants, provisions for income taxes, and fair value of lease right-of-use assets. Actual results could differ from these estimates, and such differences could be material to the Company’s consolidated financial position and results of operations.

Follow-On and At-the-Market Equity Offerings

In January 2021, the Company completed a follow-on equity offering in which it issued and sold 4,542,500 shares of its common stock at a public offering price of $38.00 per share. The Company received net proceeds of $162.3 million after deducting underwriting discounts and commissions.

In December 2021, the Company entered into an At-the-Market ("ATM") Sales Agreement (the “Sales Agreement”) with BTIG, LLC (“BTIG”) under which it may offer and sell its common stock from time to time through BTIG as its sales agent. The Sales Agreement initially capped the amount of common stock that could be sold under the Sales Agreement to $100.0 million. In December 2023, the Sales Agreement was amended to, among other things, remove the maximum dollar amount of common stock that can be sold under the Sales Agreement. BTIG will use commercially reasonable efforts to sell the Company’s common stock from time to time, based upon instructions from the Company (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company will pay BTIG a commission of up to 3% of the gross sales proceeds of any common stock sold through BTIC under the Sales Agreement. The Company is not obligated to make any sales of common stock under the Sales Agreement.

During 2023, the Company issued and sold 1,935,214 shares of its common stock at a weighted-average price of $1.85 per share under the Sales Agreement and received $3.5 million in proceeds, net of commissions.

Concentration of Credit Risk and Other Risks and Uncertainties

The Company is subject to credit risk from its portfolio of cash and cash equivalents. The Company’s cash and cash equivalents are deposited with high-quality financial institutions. Deposits at these institutions may, at times, exceed federally insured limits. Management believes these financial institutions are financially sound and, accordingly, that minimal credit risk exists.

The Company also invests in investment‐grade debt instruments and has policy limits for the amount it can invest in any one type of security, except for securities issued or guaranteed by the U.S. government. The goals of the Company’s investment policy are as follows: preservation of principal; liquidity of investments sufficient to meet cash flow requirements; avoidance of inappropriate concentration and credit risk; competitive after‐tax rate of returns; and fiduciary control of cash and investments. Under its investment policy, the Company limits the amounts invested in such securities by credit rating, maturity, investment type, and issuer. As a result, management believes that these financial instruments do not expose the Company to any significant concentrations of credit risk.

The Company purchases various reagents and sequencing materials from sole source suppliers. Any extended interruption in the supply of these materials could result in the Company’s inability to secure sufficient materials to conduct business and meet customer demand.

The Company routinely assesses the creditworthiness of its customers and does not require collateral. Historically, the Company has not experienced significant credit losses from accounts receivable. Multiple customers have provided more than 10% of total revenue in the periods presented, or accounted for more than 10% of accounts receivable at each respective balance sheet date, as follows:

Revenue Accounts Receivable

Year Ended December 31, December 31,

Merck & Co., Inc. * 11% * * *

GSK plc * * * * 12%

Pfizer Inc. * * * * 10%

* Less than 10% of revenue or accounts receivable

Revenue Recognition

The Company applies the revenue recognition guidance in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”).

The Company derives revenue from the sale of sequencing and data analysis services. Contracts are in the form of a combination of signed agreements, statements of work, and/or purchase orders. The Company accounts for a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and it is probable that the Company will collect substantially all of the consideration to which it will be entitled.

The sequencing and data analysis services are the only distinct services that meet the definition of a performance obligation and are accounted for as one performance obligation under Topic 606. Revenue is recognized at a point in time when test results are transferred to the customer. The Company has elected to exclude all sales and value added taxes from the measurement of the transaction price.

Standard payment terms are typically 90 days or less from the invoice date, but may vary. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised services to the customer will be one year or less. After assessing each of its revenue-generating arrangements to determine whether a significant financing component exists, the Company concluded that a significant financing component does not exist in any of its arrangements. The primary purpose of the Company's invoicing terms is to provide customers with simplified and predictable ways of purchasing services and to provide payment protection for the Company.

Practical Expedients and Exemptions

As a practical expedient, the Company recognizes the incremental costs of obtaining contracts, such as sales commissions, as an expense when incurred since the amortization period of the asset the Company otherwise would have recognized is one year or less. Sales commissions are recorded within selling, general and administrative expenses in the consolidated statements of operations.

Cost of Revenue

Cost of revenue consists of raw materials costs, personnel costs (salaries, bonuses, benefits, payroll taxes, and stock-based compensation), laboratory supplies and consumables, depreciation and maintenance on equipment, and allocated facilities and information technology (“IT”) costs.

Table of Contents

Research and Development Expenses

The Company charges research and development costs to expenses as incurred, including lab and automation development costs. The expenses primarily consist of personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and benefits); laboratory supplies and consumables; costs of processing samples for research, product development, collaborations, and studies; depreciation and maintenance on equipment; and allocated facilities and IT costs.

Stock-Based Compensation

For options granted to employees, non-employees, and directors, stock-based compensation is measured at grant date based on the fair value of the award. The Company determines the grant-date fair value of options using the Black-Scholes option-pricing model, except for certain performance-based awards for which an alternative valuation method may be used. The Company determines the fair value of restricted stock unit awards using the closing market price of the Company’s common stock on the date of grant. Grant-date fair value of awards is amortized over the employees’ requisite service period on a straight-line basis, or the non-employees’ vesting period as the goods are received or services rendered. Forfeitures are accounted for as they occur. Additionally, the Company’s 2019 Employee Stock Purchase Plan (the “ESPP”) is deemed to be a compensatory plan and therefore is included in stock-based compensation expense.

Inputs used in Black-Scholes option-pricing models to measure fair value of options are summarized as follows:

Expected Term. The expected term is calculated using the simplified method, which is available if there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting tranche for awards with graded vesting. The midpoint of the vesting date and the contractual expiration date is used as the expected term under this method. For awards with multiple vesting tranches, the assumed period for each tranche is computed separately and then averaged together to determine the expected term for the award.

Expected Volatility. The Company used an average historical stock price volatility of a peer group of publicly traded companies to be representative of its expected future stock price volatility, as sufficient trading history for the Company's common stock does not yet exist. For purposes of identifying these peer companies, the Company considered the industry, stage of development, size, and financial leverage of potential comparable companies. For each grant, the Company measured historical volatility over a period equivalent to the expected term.

Risk-Free Interest Rate. The risk-free interest rate is based on the implied yield currently available on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of a stock award.

Expected Dividend Rate. The Company has not paid and does not anticipate paying any dividends in the near future. Accordingly, estimated dividend yield is zero.

Foreign Currency Translation

The Company considers the functional currencies of its foreign subsidiaries to be the local currency. Assets and liabilities recorded in foreign currencies are translated at the exchange rate as of the balance sheet date, and costs and expenses are translated at average exchange rates in effect during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the consolidated balance sheets.

Comprehensive Loss

Comprehensive loss includes all changes in equity (net assets) during the period from nonowner sources. Comprehensive loss consists of net loss, cumulative translation adjustments, and unrealized gains or losses on available-for-sale debt securities.

Income Taxes

The Company uses the asset and liability method under ASC Topic 740, Income Taxes, in accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expenses or benefits are the result of changes in the deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where it is more likely than not that the deferred tax assets will not be realized.

ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC Topic 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon audit, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. ASC Topic 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the consolidated statements of operations. Accrued interest and penalties are included within the related liability line in the consolidated balance sheets.

Table of Contents

Undistributed earnings of foreign subsidiaries are assumed to be indefinitely reinvested and, accordingly, no U.S. income taxes have been provided thereon.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with original maturities at the time of purchase of three months or less. Cash equivalents include bank demand deposits and money market accounts that invest primarily in cash, U.S. Treasury bills, notes, and other obligations issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, and repurchase agreements secured by such obligations or cash. Cash equivalents also include commercial paper and U.S. Treasury bills, which are marketable debt securities recorded at fair value and accounted for in the same manner as other marketable debt securities described below.

Short-term Investments

Investments in marketable debt securities are classified as available-for-sale and recorded at fair value. Investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. Investments with maturities beyond one year are also classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. Short-term investments primarily consist of U.S. Treasury notes, U.S. Treasury bills, commercial paper, and U.S. government agency bonds.

Any discount or premium arising at purchase is accreted or amortized to interest income or expense. Unrealized gains and losses are included in accumulated other comprehensive income (loss) in stockholders’ equity. Realized gains and losses are reported in other income (expense), net. When securities are sold, any associated unrealized gain or loss initially recorded as a separate component of stockholders’ equity is reclassified out of stockholders’ equity on a specific-identification basis and recorded in earnings for the period. If an available-for-sale debt security's fair value is less than its amortized cost basis, the Company evaluates whether the decline is the result of a credit loss, in which case an impairment is recorded through an allowance for credit losses.

Fair Value Measurements

Financial assets and liabilities are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. Observable inputs reflect market data obtained from independent sources while unobservable inputs reflect market assumptions made by the reporting entity.

The three-level hierarchy for the inputs to valuation techniques used to measure fair value is briefly summarized as follows:

Level 1 — Unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets and liabilities.

Level 2 — Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 2 inputs include the following:

•

Quoted prices for similar assets and liabilities in active markets.

•

Quoted prices for identical or similar assets or liabilities in markets that are not active.

•

Observable inputs other than quoted prices that are used in the valuation of the assets or liabilities (e.g., interest rate and yield curve quotes at commonly quoted intervals).

•

Inputs that are derived principally from or are corroborated by observable market data by correlation or other means.

Level 3 — Unobservable inputs for the assets or liabilities (i.e., supported by little or no market activity). Level 3 inputs include management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk).

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

Accounts Receivable, Net

Trade accounts receivable are recorded at the invoiced amount and are noninterest bearing. The Company maintains an allowance for credit losses, consisting of known specific troubled accounts as well as an amount based on overall estimated potential uncollectible accounts receivable based on historical experience and review of their current credit quality. Expected credit losses are recorded as selling, general and administrative expenses in the consolidated statements of operations.

Table of Contents

Inventory and Other Deferred Costs

Inventory consists of raw materials and supplies used to fulfill customer contracts and the Company's research and development activities, and is valued at the lower of cost or net realizable value. Cost is determined using actual costs, on a first-in, first-out basis. Other deferred costs relate to materials consumed and work performed on customer orders that have yet to be completed and recognized as revenue and cost of revenue. Other deferred costs are also comprised of direct labor and overhead costs incurred.

Property and Equipment, Net

Property and equipment are recorded at cost, less accumulated depreciation and amortization, and are depreciated on a straight-line basis over the estimated useful lives of the related assets, which is generally three to five years for computer equipment, two years for software, three years for furniture and equipment, and five years for machinery and equipment. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the consolidated balance sheet, and the resulting gain or loss is reflected in the consolidated statements of operations. Maintenance and repairs that are not considered improvements and do not extend the useful lives of the assets are charged to expense as incurred.

Construction-in-process assets consist primarily of laboratory equipment and computer equipment that have not yet been placed in service. These assets are stated at cost and are not depreciated. Once the assets are placed into service, assets are reclassified to the appropriate asset class based on their nature and depreciated in accordance with the useful lives above.

Leases

The Company categorizes leases with contractual terms longer than 12 months as either operating or finance leases. Finance leases are generally those leases that allow the Company to substantially utilize or pay for the entire asset over its estimated life. All other leases are categorized as operating leases. As of December 31, 2023, the Company had no finance leases.

Certain lease contracts include obligations to pay for other services, such as maintenance. The Company elected to account for these other services as a component of the lease (i.e., the Company elected the practical expedient not to separate lease and non-lease components).

Lease liabilities are recognized at the present value of the fixed lease payments using a discount rate based on the Company’s current borrowing rate at the lease commencement date, adjusted for various factors including level of collateralization and term (the “incremental borrowing rate”), unless the rate implicit in the lease is readily determinable. The current portion of lease liabilities is included in “Accrued and other current liabilities.” Lease assets are recognized based on the initial present value of the fixed lease payments plus any direct costs from executing the leases and any lease prepayments. Lease assets are presented as “Operating lease right-of-use assets” as a long-term asset. Leasehold improvements are capitalized at cost and amortized over the lesser of their expected useful life or the lease term. Costs associated with operating lease assets are recognized on a straight-line basis within operating expenses over the term of the lease.

The Company has made an accounting policy election not to recognize right-of-use assets and lease liabilities that arise from leases with a term of 12 months or less. Fixed lease payments are recognized as an expense on a straight-line basis over the lease term. Variable lease costs are amounts owed by us to a lessor that are not fixed, such as reimbursement for common area maintenance, operating expenses, utilities, or other costs that are subject to fluctuation from period to period. The Company has also elected to include expenses related to leases with a term of one month or less in the short-term lease cost disclosure.

Warrant Liability

Changes in fair value of liability classified warrants are recognized within "Other income (expense), net" in the consolidated statements of operations. Warrant liabilities are classified as short-term or long-term based on their remaining contractual periods. Cash proceeds in connection with the issuance of warrants for the Company's common stock are presented as financing activities in the consolidated statements of cash flows.

Recent Accounting Pronouncements

New Accounting Pronouncements Adopted

In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, 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. The accounting update also made minor changes to the impairment model for available-for-sale debt securities. The Company adopted the new guidance as of the beginning of the first quarter of 2023 by means of a cumulative-effect adjustment to opening retained earnings. The adoption did not have a significant impact on the consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances transparency about income tax information through improvements to income tax disclosures primarily related to the rate

Table of Contents

reconciliation and income taxes paid information. The guidance will be effective for the Company's annual period ending December 31, 2025. The Company is currently evaluating the impact of the new guidance on its income tax disclosures.

Note 3. Revenue

The Company disaggregates revenue by the following four customer types:

•

Pharma tests and services includes sales of testing services and data analytics for clinical trials and research to pharmaceutical companies in support of their drug development programs. Contracts typically contemplate a single project and involve a range of tests and analytics to fulfill the requirements of each particular project.

•

Enterprise sales includes sales of tumor profiling and diagnostic tests directly to another business as an input to their products. The Company is typically contracted to deliver specified tests and analytics in high volume over time. Revenue from the Company's partnership with Natera to provide advanced tumor analysis for use in Natera's MRD test makes up substantially all of the revenue in this category.

•

Population sequencing includes sales of genomic sequencing services and data analytics to support large-scale genetic research programs. The Company is typically contracted to perform whole genome sequencing and provide data that can be used for analysis across a large volume of samples. All of the revenue within this category is from the Company's partnership with the VA MVP.

•

Other includes sales of genomic tests and analytics to universities and non-profits. Other also includes sales of diagnostics tests ordered by healthcare providers for cancer patients, which was insignificant for periods presented.

The following table presents revenue disaggregated by customer type (in thousands):

Year Ended December 31,

Revenue from countries outside of the United States, based on the billing addresses of customers, represented 10%, 9%, and 8% of the Company’s revenue for the years ended December 31, 2023, 2022 and 2021, respectively.

Contract Assets and Liabilities

The opening and closing balances of receivables and contract liabilities from contracts with customers are shown below (in thousands). Contract assets were immaterial for all periods presented.

Opening balances:

Short-term contract liabilities $ 1,264 $ 3,982

Closing balances:

Short-term contract liabilities $ 3,288 $ 1,264

Long-term contract liabilities (included in other long-term liabilities) 3,928 —

Amounts collected in advance of services being provided are deferred as contract liabilities in the consolidated balance sheets. The associated revenue is recognized, and the contract liability is reduced, as the services are subsequently performed. As of December 31, 2023, amounts related to unfulfilled services under contracts with an original expected duration of more than one year was $5.7 million. The Company expects to recognize approximately $1.8 million of this amount in the next 12 months, and the remaining $3.9 million in the 12 months after that. Revenue recognized that was included in the contract liability balance at the beginning of each reporting period was $0.4 million, $3.5 million, and $19.1 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Tempus Warrants

The Black-Scholes option-pricing model was used to estimate fair value of the warrants issued to Tempus AI, Inc. (formerly known as Tempus Labs, Inc., and referred to herein as "Tempus") at the date of issuance, November 28, 2023, and at each subsequent balance sheet date. Assumptions used are listed below, which are Level 3 fair value inputs. Expected term is equal to the remaining contractual periods of each of the two warrants. Expected volatility was based on the Company's actual historical volatility over the expected terms of the warrants. The risk-free interest rate was based on the U.S. Treasury yield curve over the expected term of the warrants. Refer to Note 8 for further information about the warrants issued to Tempus.

Equipment and Software Loans

In April 2021, the Company entered into a secured payment agreement with a financing entity to finance the purchase of $2.4 million of internal use software licenses and related software maintenance from a vendor. The financing entity and vendor are not related. The Company repaid the financed amount in three equal payments of $0.8 million in May 2021, May 2022, and May 2023. The payment agreement was noninterest bearing and the Company concluded that such interest rate (zero) did not represent fair and adequate compensation to the financing entity for the use of the related funds. Accordingly, the Company approximated the rate at which it could obtain financing of a similar nature from other sources at the date of the transaction. The resulting imputed interest rate was 7% and was used to establish the present value of the payment agreement. The discount is recognized as interest expense in the consolidated statements of operations over the life of the payment agreement.

The Company entered into two more secured payment agreements in April 2021 and July 2022, with the same financing entity, to finance the purchase of $3.1 million of computer hardware and related hardware maintenance and $1.3 million of internal use software licenses and related ongoing support, respectively. The Company is required to pay three equal payments of $1.0 million in July 2021, June 2022, and June 2023 for the first agreement, and three equal payments of $0.4 million in September 2022, September 2023, and September 2024 for the second agreement. The nature of these agreements and resulting accounting treatment are the same as the payment agreement described in the preceding paragraph, except the imputed interest rate was 9% for the July 2022 agreement.

The total initial present value of the payment agreements was $6.4 million and presented as proceeds from loans in the financing activities section of the consolidated statements of cash flows. Such proceeds were used to purchase equipment, software, and related maintenance and are reflected as cash outflows in the investing and operating activities sections. Repayments are presented as financing cash outflows. Interest expense was $0.1 million for the year ended December 31, 2023 and $0.2 million for each of the years ended December 31, 2022 and 2021.

Lab Equipment Loan

In November 2023, the Company purchased lab equipment from one of its main vendors for $3.4 million. Extended payment terms were provided to the Company through a financial solutions partner of the vendor. Terms included a 30% down payment and 24 equal monthly payments for the remaining balance, with such monthly payments commencing in January 2024, and no interest or financing charges. Title for the lab equipment transferred immediately upon delivery to the Company. The financial solutions partner retains a security interest until payoff is complete at the end of 2025. The purchase price for the lab equipment was equal to the cash price and thus the impact of imputing interest would have been de minimis.

The total financed amount of $3.4 million is presented as proceeds from loans in the financing activities section of the consolidated statements of cash flows. Such amounts were used to purchase lab equipment and are reflected as cash outflows in the investing activities section. Repayments, including both the down payment and future monthly payments, are presented as financing cash outflows.

Note 7. Leases

In 2021, the Company entered into a noncancelable operating lease for approximately 100,000 square feet in Fremont, California used for laboratory operations and its corporate headquarters. The lease term is 13.5 years and commenced in October 2022. The Company gained early access to the premises for the purpose of constructing and installing tenant improvements, for which the landlord

Table of Contents

contributed $15.1 million. Such contributions were accounted for as lease incentives and are recognized as reductions to lease expense over the lease term. The lease expires at the end of March 2036 and includes two options to extend the term for a period of five-years per option at market rates. The Company determined the extension options are not reasonably certain to be exercised. The lease includes escalating rent payments.

The Company has a noncancelable operating lease expiring in November 2027 for 31,280 square feet in Menlo Park, California previously used for laboratory operations and its former corporate headquarters. The lease includes escalating rent payments. In 2021, the Company expanded the leased premises by an additional 14,710 square feet of space (the “Expansion Lease”). The Expansion Lease expired at the end of December 2022 and was not extended. The Company moved all laboratory operations to the Fremont facility during the third quarter of 2023 and is actively marketing the vacated Menlo Park space for sublease.

The Company has noncancelable operating leases for data center space expiring between 2025 and 2026. The leases include renewal options that the Company determined are not reasonably certain to be exercised. During 2023, the data center operator agreed to terminate a portion of the lease at no cost. The Company remeasured the remaining lease liability and derecognized $0.6 million of operating lease liabilities and right-of-use assets.

The Company had an operating lease for laboratory space in Shanghai, China that was terminated early upon both parties' approval during 2023. The early termination did not result in any material penalties or charges in the Company's consolidated statements of operations. Separately, the Company also has various other short-term leases.

As of December 31, 2023, operating leases had a weighted-average remaining lease term of 10.4 years and a weighted-average discount rate of 10.5%. Discount rates are based on estimates of the Company's incremental borrowing rate, as the discount rates implicit in the leases cannot be readily determined. Future lease payments under operating leases as of December 31, 2023 were as follows (in thousands):

Amount

Total future minimum lease payments 78,623

Less: imputed interest (32,541 )

Present value of future minimum lease payments 46,082

Long-term operating lease liabilities $ 38,321

Cash paid for operating lease liabilities, included in cash flows from operating activities in the consolidated statements of cash flows, for the years ended December 31, 2023, 2022, and 2021 was $6.0 million, $4.4 million, and $3.3 million, respectively. Right-of-use assets obtained in exchange for new operating lease liabilities during the years ended December 31, 2023, 2022, and 2021 were $1.3 million, $3.1 million, and $46.5 million, respectively.

Components of lease cost were as follows (in thousands):

Year Ended December 31,

Lease cost

During the year ended December 31, 2023, the Company also recorded a $5.6 million impairment loss for operating lease right-of-use assets as a result of the change in use of the Menlo Park office.

Lease Impairment

During 2023, the Company completed the move of its laboratory operations from its Menlo Park facility to its Fremont facility and began actively marketing the Menlo Park space for sublease. Accordingly, the Company evaluated the ongoing value of the operating lease right-of-use asset associated with the Menlo Park facility. Based on this evaluation, the Company determined that the right-of-use asset with a carrying amount of $6.7 million was no longer recoverable and was impaired and wrote it down to its estimated fair value of $1.1 million, which resulted in a noncash impairment loss of $5.6 million. Estimated fair value was based on expected future sublease cash flows (with the assistance of a third-party real estate broker), net of brokerage commissions and estimated tenant incentives,

Table of Contents

discounted at a market rate of return on similar assets. The estimation of fair value also included expected downtime prior to the commencement of a future sublease.

Note 8. Tempus Agreement

Overview

On November 25, 2023, the Company entered into a Commercialization and Reference Laboratory Agreement (the “Tempus Agreement”) with Tempus pursuant to which Tempus will market the Company's Personal Dx test in the United States and the Company will conduct development activities to analytically validate the test in breast cancer, lung cancer and immuno-oncology monitoring indications. The Company will perform tests ordered by patients through Tempus and the Company will bill such patients or payors.

In consideration of the Company performing development activities, Tempus will pay the Company fees of up to $12 million (the "Market Development Fees"), consisting of an activation fee of $3 million, a first milestone fee of $3 million (upon achievement of a specified clinical validation), and a second milestone fee payable in six quarterly installments totaling $6 million (subject to achieving two additional clinical validations). If the Company does not achieve the second milestone by June 2024, Tempus may withhold installment payments, and Tempus will have the right to terminate the Tempus Agreement or convert it to a non-exclusive arrangement. Upon termination or conversion, the Company will refund to Tempus fees received other than the activation fee, subject to certain reductions.

The Company will compensate Tempus for the fair market value of order requisition services (Tempus will enable its base of ordering providers to order the Personalis test and provide specimen collection and procurement support) and results delivery services (Tempus will provide results delivery services from test completion to report delivery) on a per-test basis. In addition, the parties will perform co-promotion activities and the Company will compensate Tempus for the fair market value of promotional and commercialization services provided by Tempus in an amount up to $9.6 million.

The Tempus Agreement also grants Tempus access to initial and longitudinal genomic data derived from performance of the tests and Tempus will have the right to use such data. If Tempus licenses such data to a third party and Tempus recognizes revenue from such license, Tempus will pay the Company a percentage of its gross revenues attributable to such license that is in the range of 10 to 20 percent. Such revenue share shall be payable during the term of the agreement and for 10 years thereafter.

Additionally, in consideration of Tempus' obligations to the Company under the agreement, on November 28, 2023, the Company issued warrants to Tempus. See "Tempus Warrants" section further below for discussion.

Pursuant to the agreement, the Company will not allow another third party to market the test in such indications and Tempus will not market another tumor-informed molecular residual disease test for use in such indications (whether its own or that of a third party), in each case subject to certain exceptions. These exclusivity obligations terminate on December 31, 2027, to the extent they do not expire earlier. In addition, each party has the right to convert the Tempus Agreement to a non-exclusive arrangement upon the occurrence of certain specified events.

The term of the Tempus Agreement is five years, which may be extended for successive one-year terms. Either party may terminate the Tempus Agreement for convenience upon 18 months prior written notice. Tempus may terminate the agreement if the Company does not achieve the second milestone by a specified date.

Impact of Tempus Agreement on the Consolidated Financial Statements

The Company had achieved the first clinical validation milestone at the time of entering the Tempus Agreement and was therefore entitled to Market Development Fees of $6 million, consisting of the first milestone fee of $3 million and the activation fee of $3 million. These proceeds of $6 million were received in 2023 and allocated to the Tempus Warrants (described below). Except for receipt of the proceeds and issuance of the warrants, there were no other activities under the Tempus Agreement that impacted the Company's consolidated balance sheets or consolidated statements of operations for periods presented.

Tempus Warrants

In consideration of Tempus’ obligations to Personalis under the agreement, on November 28, 2023, the Company issued to Tempus (1) a warrant to purchase up to 4,609,400 shares of Personalis common stock at an exercise price per share of $1.50, with an expiration date of December 31, 2024 (the “First Warrant”), and (2) a warrant to purchase up to 4,609,400 shares of Personalis common stock at an exercise price per share of $2.50, with an expiration date of December 31, 2025 (the “Second Warrant” and, together with the First Warrant, the “Tempus Warrants”). The Tempus Warrants are exercisable for cash at any time prior to the applicable expiration date, may be net exercised in certain circumstances, and will be automatically net exercised in connection with a change of control of Personalis if the value ascribed to the consideration to be paid for one share of common stock is greater than the applicable exercise price. If Tempus acquires any shares of common stock directly from the Company other than by exercising the Warrants (any such shares, “Non-Warrant Shares”), then the total number of shares issuable upon exercise of the Tempus Warrants will be reduced by the Non-Warrant Shares on a share-for-share basis, proportionally between the First Warrant and the Second Warrant based on how many shares are then underlying the Warrants. Subject to limited exceptions, neither the warrants nor any interest therein may be transferred or assigned without the prior written consent of Personalis.

Table of Contents

Because the number of shares issuable upon settlement are subject to adjustment if Tempus acquires Non-Warrant Shares, the Tempus Warrants are classified as liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as Other Income (Expense) in the consolidated statements of operations. Fair value of the two warrants were estimated at the date of issuance, November 28, 2023, using the Black-Scholes option-pricing model. Since the initial fair value of $6.9 million exceeded the total proceeds from Tempus of $6 million, a loss of $0.9 million was immediately recognized within Other Income (Expense). None of the remaining Market Development Fees of $6 million were allocated to the warrants as such proceeds are contingent upon the Company achieving additional clinical validation milestones.

See Note 5 Fair Value Measurements for discussion of inputs used in the measurement of the Tempus Warrants as well as the remeasurement at December 31, 2023. Fair value of the Tempus Warrants increased by $3.1 million as of December 31, 2023. The increase in fair value, plus the immediate loss of $0.9 million recognized upon issuance, resulted in a $4.0 million expense recognized in Other Income (Expense) in the consolidated statements of operations during the year ended December 31, 2023.

Note 9. Restructuring and Other Charges

Costs related to the Company's reductions in workforce and closure of its China operations are included within Restructuring and Other Charges in the consolidated statements of operations. A reconciliation of the beginning and ending related liability balances, included within Accrued and Other Current Liabilities in the consolidated balance sheets, is as follows (in thousands):

Restructuring liability balance—December 31, 2022 $ — $ — $ —

Costs paid or otherwise settled (4,338 ) (610 ) (4,948 )

Restructuring

In January 2023, the Company initiated a reduction in workforce to reduce operating costs and improve operating efficiency. The workforce reduction affected nearly 100 employees and was substantially completed during the first quarter of 2023. The Company recognized $3.1 million in one-time employee termination benefits in connection with the reduction in workforce, comprising separation pay and healthcare benefits payable in cash, all of which were paid by the end of the second quarter of 2023.

In December 2023, the Company initiated a second reduction in workforce to further reduce operating costs and improve operating efficiency. The workforce reduction affected approximately 60 employees and will be completed during the first quarter of 2024. The Company recognized $4.0 million in one-time employee termination benefits in connection with the reduction in workforce, comprising separation pay and healthcare benefits payable in cash. Approximately $3.1 million of such expenses were unpaid as of December 31, 2023 and are expected to be paid during the first quarter of 2024. The Company does not expect to incur any material additional costs in connection with the second reduction in workforce.

Closure of China Operations

During the first half of 2023, the Company terminated its operations in China with the objective of streamlining international operations and reducing operating costs. The disposal does not qualify for reporting as a discontinued operation because it does not represent a strategic shift that has or will have a major effect on our operations and financial results. The Company completed the process of dissolving the Personalis (Shanghai) Ltd entity in February 2024.

Expenses of $0.9 million were recognized in connection with closure activities, of which $0.3 million was related to one-time employee termination benefits for the Company's 12 former employees located in China and were payable in cash. Substantially all of the terminations were completed during the first quarter of 2023, along with the related cash outlays. The remaining $0.6 million in expenses were comprised primarily of noncash charges, including losses on disposal of fixed assets and impairments of other assets.

Note 10. Stock-Based Compensation

The Company maintains the following equity incentive plans:

2011 Equity Incentive Plan

In 2011, the Company established its 2011 Equity Incentive Plan (the “2011 Plan”) that provided for the granting of stock options to employees and nonemployees of the Company. Under the 2011 Plan, the Company had the ability to issue incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, and restricted stock unit awards (“RSUs”). Options under the 2011 Plan could be granted for periods of up to 10 years. The ISOs could be granted at a price per share not less than the fair value at the date of grant.

2019 Equity Incentive Plan

The Company’s board of directors adopted and the Company’s stockholders approved the 2019 Equity Incentive Plan (the “2019 Plan”) in May 2019 and June 2019, respectively. The 2019 Plan became effective in June 2019 in connection with the Company’s IPO, and no further grants were made under the 2011 Plan. Shares reserved and remaining available for issuance under the 2011 Plan were added to the 2019 Plan reserve upon its effectiveness.

The 2019 Plan provides for the grant of ISOs, NSOs, stock appreciation rights, restricted stock awards, RSUs, performance-based stock awards, and other forms of equity compensation. Additionally, the 2019 Plan provides for the grant of performance cash awards. ISOs may be granted only to the Company’s employees and to any of the Company’s parent or subsidiary corporation’s employees. All other awards may be granted to employees, including officers, and to non-employee directors and consultants of the Company and any of the Company’s affiliates. The exercise price of a stock option generally cannot be less than 100% of the fair market value of the Company’s common stock on the date of grant. Options under the 2019 Plan may be granted for periods of up to 10 years.

2020 Inducement Plan

The Compensation Committee of the Company’s board of directors adopted the 2020 Inducement Plan (the “Inducement Plan”) in May 2020, which became effective upon adoption. The Inducement Plan was adopted without stockholder approval, as permitted by the Nasdaq Stock Market rules. The Inducement Plan provides for the grant of equity-based awards, including NSOs, stock appreciation rights, restricted stock awards, RSUs, performance-based stock awards, and other forms of equity compensation, and its terms are substantially similar to the stockholder-approved 2019 Plan. In accordance with relevant Nasdaq Listing Rules, awards under the Inducement Plan may only be made to individuals not previously employees or non-employee directors of the Company (or following such individuals’ bona fide period of non-employment with the Company), as an inducement material to the individuals' entry into employment with the Company.

2019 Employee Stock Purchase Plan

The Company’s board of directors adopted and the Company’s stockholders approved the 2019 Employee Stock Purchase Plan (the “ESPP”) in May 2019 and June 2019, respectively. Subject to any plan limitations, the ESPP allows eligible employees to contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of the Company’s common stock at a discounted price per share. The price at which common stock is purchased under the ESPP is equal to 85% of the fair market value of the Company’s common stock on the first or last day of the offering period, whichever is lower. The ESPP provides for separate six-month offering periods beginning on May 1 and November 1 of each year.

Shares of common stock available for issuance under the Company’s equity incentive plans at December 31, 2023 were as follows:

Reserved for future award grants 5,239,303

Reserved for future ESPP 83,756

Total common stock reserved for stock awards 12,382,471

Stock Option Activity

A summary of the Company’s stock option activity (excluding performance-based stock option activity summarized further below) for the years ended December 31, 2023, 2022, and 2021 is as follows:

Outstanding Options

Options exercised (8 ) 2.44

Options granted to new hires generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly thereafter. Options granted as merit awards generally vest monthly over a three- or four-year period.

The aggregate intrinsic value of unexercised stock options is calculated as the difference between the closing price of the Company’s common stock of $2.10 on December 31, 2023 and the exercise prices of the underlying stock options. Out-of-the money stock options are excluded from aggregate intrinsic value.

The weighted-average grant date fair value of options granted was $1.81, $3.21, and $13.14 per share for the years ended December 31, 2023, 2022, and 2021, respectively. As of December 31, 2023, the unrecognized stock-based compensation of unvested options was $7.2 million, which is expected to be recognized over a weighted-average period of 2.02 years.

Valuation of Stock Options

The Company estimated the fair value of stock options (excluding performance-based stock options discussed below) using the Black-Scholes option-pricing model. Fair value of stock options is recognized as compensation expense on a straight-line basis over the requisite service periods of the awards. Fair value of stock options was estimated using the following range of assumptions:

RSU Activity and Valuation

A summary of the Company’s RSU activity for the years ended December 31, 2023, 2022 and 2021 is as follows:

Unvested Restricted Stock Units

The Company grants RSUs to employees to receive shares of the Company’s common stock. The RSUs awarded are subject to the individual’s continued service to the Company through each applicable vesting date. RSUs granted to new hires generally vest annually over a four-year period. RSUs granted as merit awards generally vest semi-annually over a three- or four-year period. The Company accounts for the fair value of RSUs using the closing market price of the Company’s common stock on the date of grant.

The aggregate fair value of unvested RSUs is calculated using the closing price of the Company’s common stock of $2.10 on December 31, 2023. As of December 31, 2023, the unrecognized stock-based compensation cost of unvested RSUs was $9.5 million, which is expected to be recognized over a weighted-average period of 1.87 years.

The Company’s default tax withholding method for RSUs is the sell-to-cover method, in which shares with a market value equivalent to the tax withholding obligation are sold on behalf of the holder of the RSUs upon vesting and settlement to cover the tax withholding liability and the cash proceeds from such sales are remitted by the Company to taxing authorities.

Note 11. Commitments and Contingencies

Contingencies

On August 2, 2022, the Company filed a complaint in the U.S. District Court for the District of Colorado (the "District Court") against Foresight Diagnostics Inc. (“Foresight”) for patent infringement. The complaint is based on the Company’s U.S. Patent No. 10,450,611 (the “’611 Patent”), entitled “Personalized Genetic Testing,” our U.S. Patent No. 11,299,783 (the “’783 Patent”), entitled “Methods and Systems For Genetic Analysis,” and our U.S. Patent No. 11,384,394 (the “’394 Patent”), entitled “Methods and Systems for Genetic Analysis.” The ‘611 Patent was granted on October 22, 2019, and relates to methods for personalized genetic testing by performance of sequencing assays on biological samples. The ‘783 Patent was granted on April 12, 2022, and relates to methods for sample processing and data analysis by performance of sequencing assays on biological samples that can aid in the diagnosis, monitoring, treatment, and prevention of one or more diseases. The ‘394 Patent was granted on July 12, 2022, and relates to methods for sample processing and analysis to aid in the diagnosis, monitoring, treatment, and prevention of disease. On August 17, 2022, the Company filed an amended complaint for patent infringement against Foresight. The amended complaint added our U.S. Patent No. 11,408,033 (the “’033 Patent”), entitled “Methods and Systems for Genetic Analysis.” The ‘033 Patent was granted on August 9, 2022, and relates to methods for sample processing and analysis to aid in the diagnosis, monitoring, treatment, and prevention of disease. The Company is seeking remedies including injunctive relief, damages and costs. On October 12, 2022, Foresight filed its answer and counterclaims in the matter, seeking declaratory judgment and alleging that its solid tumor recurrence test does not infringe the Company’s asserted patents and that the claims of our asserted patents are invalid and/or unenforceable. On November 2, 2022, the Company filed its answer to Foresight’s counterclaims. The Company intends to vigorously defend against these counterclaims.

Between November 30, 2022 and February 10, 2023, inclusive, Foresight filed four inter partes review petitions with the USPTO, seeking to invalidate the four patents that we are asserting against Foresight in our first patent infringement action. Also on November 30, 2022, Foresight filed a motion to stay our first patent infringement action in the District Court pending the resolution of the inter partes review proceedings that Foresight has requested. On January 24, 2023, the District Court granted Foresight’s motion to stay. On June 13, 2023, the USPTO issued decisions granting inter partes reviews of the '394 and '033 Patents. On August 8, 2023, the USPTO issued decisions granting inter partes reviews of the '611 and '783 Patents.

On June 26, 2023, the Company filed a second complaint in the District Court against Foresight for patent infringement. The complaint is based on the Company’s U.S. Patent No. 11,584,968 (the “’968 Patent”), entitled “Methods For Using Mosaicism in Nucleic Acids Sampled Distal to Their Origin,” our U.S. Patent No. 11,649,507 (the “’507 Patent”), entitled “Methods for Using Mosaicism in

Table of Contents

Nucleic Acids Sampled Distal to Their Origin,” and our U.S. Patent No. 11,643,685 (the “’685 Patent”), entitled “Methods and Systems For Genetic Analysis.” The ’968 Patent was granted on February 21, 2023, and relates to methods for improving detection and monitoring of human diseases. The ’507 Patent was granted on May 16, 2023, and relates to methods for detection and monitoring of human disease by providing spatial or developmental localization of mutations within the body which is used in monitoring states of health in tissues of the body. The ’685 Patent was granted on May 9, 2023, and relates to methods for sample processing and analysis to aid in the diagnosis, monitoring, treatment, and prevention of disease. The Company is seeking remedies including injunctive relief, damages and costs. On August 10, 2023, Foresight filed a motion to dismiss the Company’s second complaint. On August 31, 2023, the Company filed a response to Foresight’s motion and also filed an amended complaint. On September 6, 2023, the District Court denied Foresight’s motion as moot in light of the Company’s amended complaint. On September 14, 2023, Foresight filed its answer and counterclaims in the matter, seeking declaratory judgment and alleging that its solid tumor recurrence test does not infringe the Company’s asserted patents in the Company’s second patent infringement action and that the Company’s asserted patents in that action are invalid and/or unenforceable. On October 5, 2023, the Company filed its answer to Foresight’s counterclaims. The Company intends to vigorously defend against these counterclaims.

On October 20, 2023, Foresight filed a motion to consolidate the Company’s two patent infringement actions in the District Court, and if consolidated, to maintain the stay as to all of the Company’s asserted patents pending the resolution of the first four inter partes review proceedings and the three additional inter partes review petitions that Foresight has alleged it will file as soon as it is permitted by statute to do so, seeking to invalidate the three patents that the Company is asserting against Foresight in the Company’s second patent infringement action. The Company filed its opposition to Foresight’s motion to consolidate and stay the infringement actions on November 8, 2023. On November 22, 2023, Foresight filed its fifth inter partes review petition with the USPTO, seeking to invalidate the ’968 Patent that we are asserting against Foresight in our second patent infringement action. On January 23, 2024, the District Court granted Foresight’s motion to consolidate and stay our two infringement actions against Foresight. The USPTO has yet to issue a decision regarding whether it will institute an inter partes review of our ’968 Patent.
