**Cautionary Note Regarding Forward-Looking Statements**

This Quarterly Report on Form 10-Q (this "Form 10-Q") contains forward-looking statements. In some cases, you can identify these statements by forward-looking words such as "aim," "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "potential," "predict," "should," "would," or "will," the negative of these terms, and other comparable terminology. These forward-looking statements, which are subject to risks, uncertainties, and assumptions about us, may include expectations and projections of our future financial performance, future tests or products, technology, clinical studies, regulatory landscape, compliance and strategy, potential market opportunity, increased competition, anticipated growth strategies, sufficiency of cash on hand to finance our business, seasonality, cost savings, facilities plans and lease commencement, budgets and strategies, restructuring and stock-based compensation costs, legal proceedings, impact of the restructuring on our operations, expected closing of the Samsung Investment (defined below), and anticipated trends in our business.

These statements are only predictions based on our current expectations and projections about future events and trends. There are important factors that could cause our actual results, level of activity, performance, or achievements to differ materially and adversely from those expressed or implied by the forward-looking statements, including those factors discussed under Item 1A. "Risk Factors" in this Form 10-Q and in our Annual Report on Form 10-K (filed on March 12, 2026) for the year ended December 31, 2025 (the "2025 Form 10-K"). You should specifically consider the numerous risks described under these sections. Moreover, we operate in a dynamic and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results, level of activity, performance, or achievements to differ materially and adversely from those contained in any forward-looking statements we may make.

Forward-looking statements relate to the future and, accordingly, are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict and many of which are outside of our control. Although we believe the expectations and projections expressed or implied by the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, or achievements. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Except to the extent required by law, we undertake no obligation to update any of these forward-looking statements after the date of this Form 10-Q to conform our prior statements to actual results or revised expectations or to reflect new information or the occurrence of unanticipated events.

GRAIL, Inc. ("GRAIL" or the "Company"), is an innovative commercial-stage healthcare company focused on shifting the paradigm of early cancer detection. The Company's Galleri blood test is a commercially available screening test for early detection of multiple types of cancer.

GRAIL was previously acquired by Illumina, Inc. ("Illumina") in August 2021, at which point it became a 100% owned subsidiary of Illumina, and held separate as a part of binding hold separate commitments implemented pursuant to orders issued by the European Commission (the "Acquisition").

On June 24, 2024, Illumina completed a spin-off (the "Spin-Off") through the distribution of shares of GRAIL's common stock to Illumina stockholders. In connection with the Spin-Off, the Company entered into several agreements with Illumina that govern the relationship of the parties following the Spin-Off. After the Spin-Off GRAIL became an independent public entity and GRAIL's stock began trading on the Nasdaq Stock Exchange under the ticker symbol "GRAL".

The Company had $69.3 million of cash and cash equivalents and $753.8 million of short-term marketable securities as of March 31, 2026. The Company believes that its existing cash, cash equivalents and short-term marketable securities will be sufficient to meet its working capital and capital expenditure needs for at least the next 12 months, as of the date these condensed consolidated financial statements were filed.

**NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

***Basis of Presentation and Principles of Consolidation***

The accompanying condensed consolidated financial statements and related footnotes have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary to fairly present the Company's financial position and results of operations for the interim periods presented. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, and all intercompany balances and transactions have been eliminated in consolidation. Due to the application of pushdown accounting, the Company's balance sheet includes intangible assets recognized by Illumina in connection with Illumina's acquisition of the Company.

The Company's accounting policies are described in *Note 2 — Summary Of Significant Accounting Policies*, included in the Company's Annual Report on Form 10-K (filed on March 12, 2026) for the year ended December 31, 2025 (the "2025 Form 10-K"). There have been no changes to these accounting policies during the three months ended March 31, 2026, except as described below.

***Accounts Receivable, Net***

Accounts receivable represent unconditional rights to consideration from customers. Accounts receivable are evaluated regularly for collectability and potential credit losses. Allowance for credit losses is estimated based on management's assessment of historical collection trends and current financial conditions of customers assuming those conditions as of the balance sheet date do not change for the remaining life of the asset, among other factors. These reserves are re-evaluated on a regular basis and adjusted, as needed. Once a receivable is deemed to be uncollectible, the receivable balance is charged against the reserve. As of March 31, 2026, and December 31, 2025, the Company had $3.7 million and $3.6 million of allowance for credit losses.

***Concentration of Credit Risk***

*Financial Instruments*

The Company is subject to credit risk from its portfolio of cash, cash equivalents and short-term marketable securities held at three accredited financial institutions. As of March 31, 2026, the Company had $69.3 million of cash and cash equivalents, and short-term marketable securities of $753.8 million. The Company limits its exposure to credit losses by investing in money market funds and United States ("U.S.") government treasury securities through U.S. banks with high credit ratings. The Company's cash consists of deposits held with banks that may at times exceed federally insured limits, however, its exposure to credit risk in the event of default by the financial institution is limited to the extent of amounts recorded on the condensed consolidated balance sheets. The Company performs evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company has not experienced any losses in such accounts.

As of March 31, 2026, the Company had no off-balance sheet concentrations of credit risk.

*Customers*

The Company is subject to credit risk related to its accounts receivable. Accounts receivable primarily arise from testing services performed in the U.S. and are primarily with biopharmaceutical companies, healthcare organizations, employers, digital health platforms, concierge medicine practices, life insurance companies, Centers for Medicare & Medicaid Services, and individuals. The Company does not require collateral. Accounts receivable are recorded net of the allowance for credit losses.

Significant customers are those that represent more than 10% of total revenue or accounts receivable, net for the periods and as of each consolidated balance sheet date presented, respectively.

For the quarter ended March 31, 2026, one customer accounted for 11% of the Company's revenue. For the quarter ended March 31, 2025, no single customer accounted for 10% or more of the Company's revenue.

As of March 31, 2026, and December 31, 2025 no single customer accounted for 10% or more of the Company's account receivable, net.

*Suppliers*

The Company is subject to a concentration risk for equipment, supplies and reagents that are available from a limited number of sources. The Company sources certain laboratory equipment, supplies and reagents used to perform testing services and research and development from single vendors. Historically, the Company has not experienced significant issues sourcing equipment and supplies needed to perform testing services.

***Reclassification***

Certain amounts within the segment disclosure in the footnote to the condensed consolidated financial statements for the period ended March 31, 2025 have been conformed to the current period presentation.

***Recently Adopted Accounting Pronouncements***

In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update provides entities with a practical expedient related to developing reasonable and supportable forecasts as part of estimating expected credit losses, in which entities may elect to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. The Company adopted the standard on a prospective basis effective January 1, 2026, and elected the practical expedient. Adoption of this guidance did not have a material impact on the Company's condensed consolidated financial statements.

**Long-lived assets**

On February 19, 2026, the Company issued a press release announcing top-line results from its NHS-Galleri trial. Immediately following the release of this information, the Company's market capitalization decreased materially. This sustained decrease in market capitalization represented a possible impairment indicator that warranted a quantitative impairment analysis of the Company's long-lived assets.

The Company performed a recoverability test at the asset group level, which was determined to be equivalent to its reporting unit to assess potential impairment of long-lived assets, which consist primarily of intangible assets with finite lives.

The Company performed an undiscounted cash flow analysis to assess whether the expected cash flows generated over the remaining estimated useful life of the primary asset within the asset group are sufficient to recover its carrying value. Significant assumptions underlying the forecasted cash flows include estimates of future revenues, costs, and expenses. These estimates involve a high degree of judgment regarding future events and are based on assumptions that management believes are reasonable. Changes in these estimates or assumptions could materially affect the recoverability assessment.

The results of the recoverability test showed that the estimated undiscounted net cash flows to be generated from the use of the Company's long-lived assets exceeded its net carrying value. As a result, no write-down of long-lived assets was recognized during the quarter ended March 31, 2026.

All of the Company's marketable securities had maturities of less than one year.

The Company had eight securities with a fair value of $404.6 million in an unrealized loss position as of March 31, 2026 and no securities in unrealized loss position as of December 31, 2025. None of the Company's marketable securities had been in an unrealized loss position for more than one year as of March 31, 2026. It was determined that no credit losses exist as of March 31, 2026 because the change in market value for those securities that were in an unrealized loss position resulted from fluctuating interest rates rather than a deterioration of the credit worthiness of the issuers. The Company does not intend to sell the money market funds and short term investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis.

**NOTE 6. LEGAL PROCEEDINGS, COMMITMENTS, AND CONTINGENCIES**

The Company is subject to various claims, complaints, regulatory proceedings, and legal actions that arise from time to time in the ordinary course of business.

***Federal Securities Class Actions***

On November 11, 2023, the first of three securities class action complaints was filed against Illumina and certain of its current and former executive officers in the United States District Court for the Southern District of California. The first-filed case is captioned Kangas v. Illumina, Inc. et al., the second-filed case is captioned Roy v. Illumina, Inc. et al., and the third-filed case is captioned Louisiana Sheriffs' Pension & Relief Fund v. Illumina, Inc. et al. (collectively, the "Actions"). The complaints generally allege, among other things, that defendants made materially false and misleading statements and omitted material facts relating to Illumina's acquisition of Grail. The complaints seek unspecified damages, interest, fees, and costs. On January 9, 2024, four movants filed motions to consolidate the Actions and to appoint a lead plaintiff ("Lead Plaintiff Motions"). On April 11, 2024, the Court issued an order consolidating the Actions into a single action (captioned in re Illumina, Inc. Securities Litigation No. 23-cv-2082-LL-MMP), and appointed Universal-Investment-Gesellschaft mbH, UI BVK

Kapitalverwaltungsgesellschaft mbH, and ACATIS Investment Kapitalverwaltungsgesellschaft mbH as lead

plaintiffs. (the "Lead Plaintiffs"). On June 21, 2024, the Lead Plaintiffs filed a consolidated amended complaint. The amended complaint alleges that GRAIL, in addition to Illumina, and certain of their respective current and former directors and others violated sections 10(b) and 20(a) of the Securities Exchange Act and SEC Rule 10b-5 in connection with Illumina's acquisition of GRAIL and disclosures concerning the same. GRAIL has an indemnification obligation for certain current and former directors and officers involved in the matter pursuant to indemnification agreements entered into by these individuals and GRAIL. On September 13, 2024 the plaintiffs further amended the complaint. On November 12, 2024, the Company moved to dismiss Lead Plaintiffs' second amended complaint for failure to state a claim under Sections 10(b) and 20(a) of the Exchange Act. Lead Plaintiffs filed their opposition to the motion to dismiss on December 20, 2024, and the Company filed its reply in support of its motion to dismiss on February 3, 2025. On September 26, 2025, the court granted the motion to dismiss for failure to state a claim with leave to amend, and ordered the plaintiffs to file an amended complaint, if any, by October 27, 2025. On October 27, 2025, the Lead Plaintiffs filed their third amended complaint. On December 11, 2025, the Company filed a motion to dismiss Lead Plaintiffs' third amended complaint. On February 4, 2026, the Lead Plaintiffs opposed the motion to dismiss, and on March 6, 2026, the Company filed a reply in support of its motion to dismiss. In light of the fact that the lawsuits are in an early stage, the Company cannot predict the ultimate outcome of the suits.

***Other Legal Matters***

Legal matters include various claims, complaints, and legal actions that arise from time to time. The Company has entered into indemnification agreements with each of its current and former directors, executive officers, and certain other officers, to provide, among other things, for indemnification to the fullest extent permitted by law and our certificate of incorporation and bylaws, and has certain obligations to these individuals, which may give rise to liability for the Company even if the Company is not directly named. The Company has indemnification obligations in respect of the Actions and with respect to other legal matters that may arise, or have arisen, from time to time. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on the Company's business, financial position, results of operations, or cash flows.

The Company is involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to employment matters. In connection with these matters, the Company assesses, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the consolidated financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Since litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. The Company regularly reviews outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures. The Company may change its estimates if its assessment of the various factors changes and

(unaudited)

the amount of ultimate loss may differ from estimates, resulting in a material effect on the Company's business, financial condition, results of operations, and/or cash flows. As of March 31, 2026, the Company is unable to estimate a range of possible loss in excess of the amounts accrued.

***Contingencies***

Contingencies primarily correspond to claims arising in the ordinary course of business. If necessary, these contingencies will be accrued, to the extent believed to be reasonably estimable to resolve the matter. The accrued contingency amounts are included in other current liabilities. Should the Company not be able to secure the terms it expects, these estimates may change and will be recognized in the period in which they are identified.

On June 21, 2024, in connection with the Spin-Off, Illumina and the Company entered into the Tax Matters Agreement to govern the respective rights, responsibilities and obligations of Illumina and the Company after the Spin-Off with respect to all tax matters and will include restrictions to preserve the tax-free status of the Distribution. The Tax Matters Agreement included a number of restrictions on the Company to preserve the intended tax treatment of the Spin-Off. Breach of any covenant or representation contained in the Tax Matters Agreement will result in liability to specific separation taxes. As of March 31, 2026, as it was not probable that the Company will breach the agreement, no contingent liability was recorded in connection with the Tax Matters Agreement.

***Samsung Stock Purchase Obligations***

On October 16, 2025, the Company entered into a stock purchase agreement (the "Samsung SPA"), by and among the Company, Samsung C&T Corporation ("Samsung C&T"), Samsung Electronics Singapore Pte. Ltd. (together with Samsung C&T, the "Samsung Investors") and Samsung Electronics Co., Ltd. ("Samsung Electronics"), providing for the issuance and sale by the Company to the Samsung Investors in a private placement of an aggregate of 1,570,308 shares of GRAIL's common stock, at a purchase price of $70.05 per share, upon the terms and conditions set forth in the Samsung SPA, for aggregate gross proceeds of approximately $110.0 million (the "Samsung Investment"). The Samsung Investment is subject to the satisfaction of certain closing conditions set forth in the Samsung Stock Purchase Agreement, including, but not limited to the satisfaction of certain regulatory approvals or clearances, including with respect to the Committee on Foreign Investment in the United States.

The Company is also subject to a number of obligations described in the Samsung Stock Purchase Agreement. The Samsung Stock Purchase Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Samsung Investors for liabilities under the Securities Act of 1933, as amended (the "Securities Act"), and other obligations of the parties.

Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share, as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive.

The following common stock equivalents were excluded from the calculation of diluted net loss per share for the periods presented as they had an anti-dilutive effect:

**NOTE 8. TAXES**

For interim financial statement purposes, U.S. GAAP provision (benefit) for taxes related to ordinary income (loss) is determined by applying an estimated annual effective income tax rate against a company's ordinary income (loss), subject to certain limitations on the benefit of losses. Provision (benefit) for taxes related to items not characterized as ordinary income is recognized as a discrete item when incurred. The estimation of the Company's income tax provision requires the use of management forecasts and other estimates, application of statutory income tax rates, and an evaluation of valuation allowances. The Company's estimated annual effective income tax rate may be revised, if necessary, in each interim period.

The worldwide effective income tax rates for the three months ended March 31, 2026 and March 31, 2025 were 26.93% and 27.41%, respectively. The decrease in benefit from income taxes was primarily driven by decrease in the loss before taxes and a lower effective tax rate primarily due to fewer discrete tax items related to stock-based compensation expenses.

The effective tax rate was higher than the 21% U.S. federal statutory rate for the three months ended March 31, 2026, primarily due to state taxes and discrete tax benefits from stock-based compensation.

The Company accounts for uncertain tax positions using a more-likely-than-not threshold for recognizing and

resolving uncertain tax positions. This evaluation is based on factors including, but not limited to, changes in facts

or circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. Interest and

penalties related to unrecognized tax benefits are included within income tax expense. For the three months

ended March 31, 2026, the Company recorded an income tax benefit related to its Federal and California R&D

Credits of $0.7 million and $0.4 million, respectively.

The Company files income tax returns in the U.S. federal jurisdiction and various states. As of the date of

this filing, the Company is not currently under examination by income tax authorities in federal, state, or other

jurisdictions. All tax returns will remain open for examination by the federal and state authorities for three and four

years, respectively, from the date of utilization of any net operating loss or credits.

**NOTE 9. SEGMENT INFORMATION**

The Company operates and manages its business as one reportable operating segment. The Company's chief operating decision maker ("CODM") is the chief executive officer. The CODM reviews financial information on an aggregate basis for the purposes of evaluating financial performance and allocating resources based on net income (loss), adjusted gross margin and adjusted EBITDA. Net income (loss) is the measure of segment profit most consistent with U.S. GAAP that is regularly reviewed by the CODM to allocate resources and assess performance. The CODM does not evaluate operating segment performance using asset information.

The following table includes the significant expense categories regularly provided to the CODM when managing the Company's single reporting segment. A reconciliation to the consolidated net loss for the three months ended March 31, 2026 and March 31, 2025 is included in the table below:

**NOTE 10. RELATED PARTY TRANSACTIONS**

The Company was a subsidiary of Illumina, Inc. between August 19, 2021 to June 23, 2024. Subsequent to the Spin-Off, Illumina retained a 14.5% stake in the Company and was considered a related party. During the fourth quarter of 2025, Illumina reduced its ownership to less than 10%. As a result, Illumina is no longer considered a related party of the Company.

Illumina was both a customer and a major supplier of the Company's reagents and capital equipment during the relevant periods. Goods and services transactions with Illumina are invoiced and paid when due.

Goods and services transactions with Illumina for the period during which Illumina qualified as a related party of the Company were as follows:

---

| | |
|:---|:---|
| | **Three Months Ended** |
| (in thousands) | **March 31,<br>2025** |
| Screening revenue | $77 |
| Cost of screening revenue | 1511 |
| Cost of development services revenue | 163 |
| Operating expenses—Research and development | 1396 |

---

In June 2024, the Company entered into an amendment to its Supply and Commercialization Agreement with Illumina (the "Illumina Supply Agreement"). Under the terms of the Illumina Supply Agreement, regardless of whether our products incorporate any Illumina technology, we will be obligated to pay Illumina a 9% royalty, subject to certain reductions and floors, in perpetuity on net sales generated by our products or revenues otherwise generated or received by us, subject to certain exceptions, in the field of oncology. The royalty is subject to anti-stacking provisions that allow royalty payments we make to other third parties to be deducted from the 9% royalty rate, to a floor of 7%. We expect that the royalty payments we will make to Illumina in the foreseeable future will result in a 7% royalty rate. After we have cumulatively paid Illumina royalties totaling $1 billion, the royalty rate will be reduced to 5%, without further adjustment.

Pursuant to the fourth amendment to the Illumina Supply Agreement, the perpetual royalty payment obligation to Illumina is suspended until December 24, 2026 or any earlier change of control of GRAIL, at which time royalty payments to Illumina will resume, without retroactive effect. Any royalty payments that we would have made under the Illumina Supply Agreement during the suspension period are deemed to have been paid for purposes of the cumulative $1 billion in royalty payments required to reduce the royalty rate to 5%.

**Overview**

***Our Business***

We are an innovative commercial-stage healthcare company focused on shifting the paradigm in early cancer detection at population scale. We believe screening individuals for many types of cancer with a single test represents a significant opportunity to reduce the global burden of cancer. Our multi-cancer early detection test ("Galleri") can screen for many types of cancer, accurately predicting the specific organ or tissue type where the cancer signal originated (the "Cancer Signal of Origin", or "CSO"), with high positive predictive values ("PPV") and low false positive rates, all from a simple blood draw. Galleri has detected some of the most aggressive cancers in early stages including, among others, endometrial, esophageal, gastrointestinal, head and neck, liver, pancreatic, and rectal cancers. We have conducted what we believe is the largest clinical program in genomic medicine to date with data from over 385,000 participants that we believe demonstrate the clinical validation and clinical utility of Galleri in its intended use population. We have deep operational experience with over 860,000 tests processed across this clinical program and from our commercial experience, including through partnerships with leading healthcare systems, employers, digital health platforms, payors, and life insurance providers.

Recently we announced results from two of our large clinical trials, PATHFINDER 2 and NHS-Galleri Trial, and included certain results from those studies in our pre-market approval application ("PMA") to the Food and Drug Administration ("FDA"), the last module of which we submitted in January 2026. Performance and safety data focused on the first approximately 25,000 participants of our approximately 35,000 participant PATHFINDER 2 study were presented at the European Society for Medical Oncology ("ESMO") in October 2025 (the "PATHFINDER 2 Initial Results") and demonstrated that adding Galleri to recommended (breast, cervical, colorectal and lung) screenings led to a more than seven-fold increase in the number of cancers found within a year, and an approximately three-fold increase when prostate screening was included. Results from the full approximately 35,000 participants in the PATHFINDER 2 study were generally consistent with the results presented at ESMO. We also announced topline results from our three year, randomized controlled NHS-Galleri Trial which demonstrated a substantial reduction in stage 4 cancer diagnoses, increased stage 1 and 2 detection of deadly cancers, and four-fold higher cancer detection rate when compared to recommended screenings alone, although the primary endpoint of statistically significant combined stage 3 and 4 reduction was not observed. However, there was a favorable trend toward fewer combined stage 3 and 4 cancers in a pre-specified group of

------

12 deadly cancers in the intervention arm after the prevalent screening round. The PATHFINDER 2 Initial Results and the performance and safety metrics from the first year (prevalent screening round) of our NHS-Galleri Trial were included in our PMA submission, along with results of a bridging study.

We designed Galleri to detect cancer early, when it is more amenable to curative treatment, and we launched Galleri in the United States in mid-2021. Galleri works by detecting DNA fragments shed into the bloodstream by tumor cells and analyzing specific methylation patterns that can be used to both identify a general cancer signal and localize that signal to a specific organ or tissue type. We have sold over 530,000 commercial Galleri tests through March 31, 2026, with over 56,000 sold during the three months ended March 31, 2026. These tests have detected some of the most aggressive cancers in early stages including, among others, endometrial, esophageal, gastrointestinal, head and neck, liver, pancreatic, and rectal cancers.

As an early pioneer of MCED testing, we have established strong relationships within the cancer and primary care community, including through partnerships with academic and community medical centers, key opinion leaders, and governmental policy and advocacy partners. We have shared evidence supporting our MCED testing at renowned medical conferences, such as the American Association of Cancer Research ("AACR"), American Society of Clinical Oncology ("ASCO"), ESMO, and American Academy of Family Physicians ("AAFP"). We have also published results from our studies in leading scientific and medical journals, including The Lancet, Nature, Nature Medicine, Cancer Cell, and The Lancet Oncology.

Since our inception, we have incurred net losses each year. We incurred net losses of $93.2 million and $106.2 million for the three months ended March 31, 2026 and March 31, 2025. Substantially all of our net losses resulted from the application of pushdown accounting, including goodwill and intangible asset impairments and the amortization of intangible assets, as well as our research and development programs, general and administrative costs associated with our operations, and sales and marketing costs associated with commercializing our products. As a result of the application of push down accounting, our balance sheet includes intangible assets, which may be subject to additional impairment over time. We expect to continue to incur operating losses for at least the next several years as we invest in research and development and the commercialization of existing products.

Adjusted EBITDA was $(79.9) million and $(98.7) million for the three months ended March 31, 2026 and March 31, 2025. Adjusted EBITDA is a non-GAAP financial measure. For a reconciliation of Adjusted EBITDA to the most directly comparable U.S. generally accepted accounting principle ("GAAP") financial measure, information about why we consider Adjusted EBITDA useful and a discussion of the material risks and limitations of these measures, please see "Non-GAAP Financial Measures" below.

***Key Factors Affecting Performance***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***FDA and other regulatory approval and reimbursement****.* Our performance will be impacted by the extent to which we can secure reimbursement and coverage for Galleri. Prior to broader coverage and reimbursement in the United States, we will continue our work with clinics and health systems to accelerate utilization, and with self-insured employers and health insurers to offer and cover Galleri. Galleri is currently available as a laboratory developed test ("LDT") in the United States and we have established coverage and reimbursement from a number of self-insured employers and health plans, including coverage from TRICARE, but we do not currently have broader coverage and reimbursement by Medicare or large commercial insurers. While Galleri has not been approved or cleared by the FDA, FDA approval is currently not required to market our test in the United States. We are pursuing FDA approval to help support broad access for Galleri in the United States and we submitted a PMA for Galleri to the FDA in January 2026. Obtaining PMA approval can take several months or years from the time an application is submitted, if at all. Moreover, the regulatory requirements surrounding the pathway to PMA for laboratory tests has in the recent past, and may in the future, be subject to change. We believe that FDA approval, if obtained, could unlock coverage from large commercial payors in the United States. In February 2026, a new law created a coverage benefit category to enable coverage of FDA-approved MCED tests by Medicare, with authority for Centers for Medicare and Medicaid Services

------

("CMS") to initiate coverage as early as January 1, 2029 for the aged 50-65 Medicare population and expanding one age-year at a time annually. If we obtain FDA approval, we expect to pursue coverage through this new law and, subsequently, inclusion of Galleri in the United States Preventive Services Task Force ("USPSTF") guideline recommendation, although such inclusion may take years and is not certain even with FDA approval. Should USPSTF recommend Galleri with an A or B recommendation, CMS would then have the authority to expand coverage beyond what is covered under the MCED benefit category. We believe FDA approval and, to a greater extent, inclusion in USPSTF guideline recommendations would further increase adoption and market acceptance of our tests. Over time, we have and may continue to opt to provide rebates or discounts to certain customers, or reduce pricing in order to access a broader population base and accelerate adoption. In the United Kingdom, NHS England (which is being merged with the Department of Health and Social Care) (the "NHS") will evaluate the final results from the NHS-Galleri Trial before determining whether to implement the Galleri test in the NHS. Under our agreement with the NHS, these results have met certain success criteria and missed others. As a result, we and NHS England will convene meetings of our joint steering committee to discuss how best to proceed with deployment to the UK population, if at all, considering deployment approaches and which population groups would most benefit. We believe the decision will include considerations such as NHS budget, political priorities, cost-effectiveness and implementation constraints in addition to an evaluation of the final results. We also believe our work with the NHS and the data generated from our NHS-Galleri Trial could help facilitate adoption in other single-payor systems around the world and support evidence of clinical utility worldwide. Although the primary endpoint of statistically significant combined stage 3 and 4 reduction was not observed in the NHS-Galleri Trial, we believe other results from the trial could be compelling to these systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***International expansion***. A component of our long-term growth strategy is to expand our commercial reach internationally. We have expanded our research internationally into the United Kingdom through our partnership with NHS England in the NHS-Galleri Trial, and we expect to launch Galleri in the United Kingdom, following any positive NHS evaluation of the final results from the NHS-Galleri Trial. We continue to evaluate international expansion opportunities and we have begun expansion in select additional geographies through distributors, including Israel and Canada, and proposed expansion in South Korea through our partnership with Samsung. We expect to continue selectively engaging with international opportunities over time. Our ability to expand into new regions and jurisdictions, drive commercial sales and growth within those regions and jurisdictions and navigate economic, political, regulatory, and other risks, including geopolitical conflict associated with international operations, will be an important driver of our performance.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Continued development of, and competition within, the market for MCED testing****.* Multi-cancer early detection is a novel technology and the market for MCED tests is evolving. We continue to drive MCED as a solution to one of healthcare's most important challenges. Our performance depends on the extent to which key stakeholders, including current and potential commercial partners, payors and health systems, regulators, policy makers, academic and community medical centers, and key opinion leaders and advocates, understand and support MCED testing as an effective solution for cancer screening. We make significant efforts to educate these key stakeholders regarding the benefits of MCED and the clinical and economic value of our products, which we believe will continue to drive awareness of MCED and expand the commercial opportunity for our products. Additionally, new MCED products from new market entrants launched commercially in the second half of 2025. We believe that the addition of new market entrants will help develop the market for MCED testing. However, these competitors will also be targeting similar markets as us and may compete with us for customers on characteristics of their tests, such as test performance, ease of use and cost. These companies may also present clinical or other information, such as test performance information, that differs from our own presentation of similar information. Our ability to differentiate Galleri from other MCED products and any such presented data will be a key factor in our success. We believe we are differentiated by our extensive and robust datasets generated from our clinical studies, our rigorous and objective approach to test development and research, our multidisciplinary capabilities leveraging the power of next-generation sequencing and advanced and trained machine learning algorithms and data science, our robust intellectual property portfolio, and our investment in our facilities and operational workflows. However, certain new market entrants may have greater financial resources, quicker reimbursement timelines, larger sales forces, more successful marketing campaigns, more experience in screening or international commercialization, lower prices or other advantages. Our ability to succeed will depend on our market success. See Item 1A. "Risk Factors".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Demand for our products and customer mix****.* A key factor to our future success is and will be our ability to increase demand for, and sales of, Galleri from new and existing customers. Our commercial strategy is focused on innovative value-oriented partnerships and targets primary care physicians, health systems, employers, digital health platforms, payors, and life insurance providers. As Galleri is not currently broadly reimbursed, our ability to drive demand from these customers is directly linked to our ability to demonstrate the clinical and economic value of our test through clinical validation and real-world experience. As of March 31, 2026, we have entered into commercial partnerships, including with leading healthcare systems, digital health platforms, employers, payors, and life insurance providers, and have established a network of approximately 19,000 prescribers across the United States in a pre-reimbursement setting. We believe this commercial network represents a significant opportunity to drive further demand for Galleri. The mix of customers from which we generate revenue from period to period has an impact on our revenue and gross margin. Galleri test pricing is generally based on our list price, with discounts in certain channels, or, for certain customers, such as larger, higher-volume customers or international distributors, negotiated contractual rates. For certain customers, we also offer rebates. Revenue generated from customers with negotiated contractual rates, or with rebates or discounts, is generally lower margin as compared to revenue generated based on list pricing. We expect the number or magnitude of these rates, discounts and rebates to reduce our average selling price ("ASP") over time. In addition, we have entered into a number of biopharmaceutical research partnerships for our research-use-only ("RUO") offering under our precision oncology portfolio. Large customers, such as healthcare systems, employers, and biopharmaceutical partners, generally begin using our products by initiating pilots involving a limited number of tests. We believe that our ability to convert these initial pilots into long-term customer relationships has the potential to drive substantial long-term revenue. Termination of these pilots or clinical trials can have a significant impact on our revenue and results of operations. For example, in late 2025, one of our pharmaceutical partners terminated its phase 3 trial due to low enrollment, for which our methylation technology was used as a potential companion diagnostic for enrolling participants. We also expect to increase demand from new customers through our efforts to further develop the market for MCED testing.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Investment in clinical studies and innovation to support our strategy and growth****.* A significant aspect of our business is our investment in research and development and the ongoing evidence generation supporting the clinical performance and utility of Galleri. In particular, we have invested heavily in clinical studies and designed and executed what we believe is the largest clinical program in genomic medicine to date. These studies include: NHS-Galleri, PATHFINDER, PATHFINDER 2, CCGA, REACH/Galleri-Medicare, REFLECTION, STRIVE, SUMMIT, and SYMPLIFY. We have established and maintained a leading voice in conversations regarding the early detection of multiple cancer types in the peer-reviewed literature. We have published data from these studies in high-profile journals and have presented such data at renowned medical conferences. We believe these studies are critical to driving adoption of our tests, as well as favorable coverage decisions, and expect to continue investment in data generation. In addition, we have invested heavily in the development of our methylation platform and extensive technological infrastructure. We expect our research and development expenses to decrease over the next three years as, following our Spin-Off, in conjunction with a portfolio review, we determined to decrease investment in product programs beyond Galleri. Additionally, we expect to see a relative decrease in research and development expenses as we have progressed most of our large clinical trials into the data follow-up phase, development of our automated platform has substantially concluded and we have substantially completed development of enhanced versions of our Galleri test, including the version that we use in commercial channels and the updated version that was submitted with our PMA. We will continue to prioritize key objectives for Galleri, including generating and reporting clinical utility evidence to support broad adoption of Galleri and progressing our PMA towards potential approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Leverage our operational infrastructure***. We have made significant investments to build a scalable infrastructure capable of meeting significant demand of up to one million tests per year while satisfying applicable certification and licensing requirements and accreditation standards. Our Durham, North Carolina facility is CAP-accredited and CLIA-certified. In addition, we engineered custom technology infrastructure and cloud-based tools to enable scalable data collection and analysis capabilities. With this foundational infrastructure in place, we have been able to generate scale efficiencies as the volume of tests sold has increased. As demand for our products increases, we expect to further leverage the scale efficiencies of our infrastructure and platform technology, which we believe will positively impact margins over time. In late 2024, we began using an updated version of Galleri in commercial channels. This version incorporates a highly-automated industrial scale platform and is intended to enable us to scale more efficiently with future demand. In connection with implementation of this new version of Galleri, we have experienced and may continue to experience increased turnaround times, re-processing costs and sample failures. We continually monitor and evaluate laboratory operations and performance in an effort to achieve our intended sample processing metrics and costs; however from time to time, processing issues may arise that could impact our operations. In the future, it is possible that we may invest significant amounts in infrastructure to support new products or existing products in new markets.

Seasonal fluctuations and underlying business trends have also affected, and are likely to continue to affect, our business. We may experience this seasonality, in particular in the third quarter due to primary care physician and patient summer vacation periods, with relatively lower volume in the first and third quarters, and relatively higher volume in the second and fourth quarters. These seasonal trends have caused, and will likely continue to cause, fluctuations in our quarterly results, including fluctuations in sequential revenue growth rates.

While each of these areas presents significant opportunities for us, they also pose significant risks and challenges that we must address. See Item 1A. "Risk Factors" for more information.

------

***Components of Results of Operations***

*Screening Revenue*

We currently derive screening revenue through the sale of Galleri primarily within the United States and primarily through primary care physicians, health systems, employers, digital health platforms, payors, and life insurance providers. Galleri is not currently broadly reimbursed. Galleri test pricing is generally based on our list price, with discounts in certain channels, or, for certain customers, such as larger, higher-volume customers or international distributors, negotiated contractual rates. For certain customers, we also offer rebates. We expect the number or magnitude of these rates, discounts and rebates to reduce our ASP over time. We identify each sale of our test to our customer as a single performance obligation; therefore, revenue is recognized at the point of time when the test result report is delivered. For self-pay patients, we have concluded that an implied contract exists, however the transaction price for the implied contract represents variable consideration as there are situations in which we do not expect to collect the full invoiced amounts from self-pay patients due to price concessions. We utilize the expected value approach to estimate the transaction price and apply a constraint for such variable consideration, on a portfolio basis. We monitor the estimated amounts to be collected at each reporting period based on actual cash collections in order to assess whether a revision to the estimate is required.

*Development Services Revenue*

We also derive revenue through our development services, which consist of research services we provide to biopharmaceutical and clinical customers including support of ongoing clinical studies, pilot testing, research, and therapy development. We evaluate the terms and conditions included within our development services contracts with biopharmaceutical customers to ensure appropriate revenue recognition, including whether services are considered distinct performance obligations that should be accounted for separately versus together. Revenue from pilot and research services performed is recognized as performance obligations are achieved. We recognize revenue from development service agreements related to regulatory filings to support clinical study and companion diagnostic device development and regulatory submissions for the developed product(s) using an input method based on costs incurred to measure its progress toward the completion and satisfaction of the performance obligations.

*Cost of Screening Revenue (Exclusive of Amortization of Intangible Assets) and Cost of Development Services Revenue*

Cost of revenue represents expenses that are incurred to produce and sell our products and services. For screening revenue, these costs consist of materials, labor including salaries and wages, bonus, benefits and stock-based compensation, blood collection kits and shipping, phlebotomy, royalties, electronic medical records, equipment depreciation, and allocations of overhead expenses such as facilities and information technology costs. For development services, these costs consist of materials and patient sample acquisition, labor including salaries and wages, bonus, benefits and stock-based compensation, royalties, equipment depreciation, and allocations of overhead expenses such as facilities and information technology costs. As demand for our products increases, we expect to further leverage the scale efficiencies of our infrastructure and platform technology, which we believe will positively impact margins over time. These margin improvements from scale efficiencies will at least be partially offset when we commence recognition of royalties owing under the terms of the Illumina Supply Agreement on December 24, 2026.

*Cost of Revenue—Amortization of Intangible Assets*

As a result of the application of pushdown accounting, intangible assets recognized in our standalone financial statements relate to our own technology, and consist of developed technologies and in-process research and development that were measured at fair value upon the Acquisition. Our developed technology includes intangible assets related to Galleri, designed as a cancer screening test for asymptomatic individuals over 50 years of age, as well as our diagnostic aid for cancer ("DAC") product that is being designed to accelerate diagnostic resolution for patients for whom there is a clinical suspicion of cancer. As part of our restructuring plan designed to reprioritize our resources to focus on our core MCED business and reduce overall spend as we pursue a PMA approval from the FDA for Galleri and broad reimbursement, we have reduced investment in the development of products beyond Galleri, including DAC. The cost of identifiable intangible assets with finite lives,

------

such as developed technology assets, are amortized on a straight-line basis over the assets' respective estimated useful lives of 18 years.

*Research and Development* 

Research and development expenses include costs incurred to develop our technology (prior to establishing technological feasibility), collect clinical samples, and conduct clinical studies to develop and support our products. These costs consist of personnel costs, including salaries, benefits, and stock-based compensation expense associated with our research and development personnel, costs associated with setting up and conducting clinical studies at domestic and international sites, laboratory supplies, consulting costs, depreciation, and allocated overhead including facilities and information technology expenses, which we do not allocate by product. We expense both internal and external research and development costs in the periods in which they are incurred. Nonrefundable advance payments for goods and services that will be used or rendered in future research and development activities are deferred and recognized as expenses in the period in which the related goods are delivered or services are performed. We expect our research and development expenses to decrease over the next three years as, following our Spin-Off, in conjunction with a portfolio review, we determined to decrease investment in product programs beyond Galleri. Additionally, we expect to see a relative decrease in research and development expenses as we have progressed most of our large clinical trials into the data follow-up phase, development of our automated platform has substantially concluded and we have substantially completed development of enhanced versions of our Galleri test, including the version that we use in commercial channels and the updated version that was submitted with our PMA.

*Sales and Marketing*

Sales and marketing expenses consist primarily of personnel costs, including salaries, benefits and stock- based compensation expense, consulting costs, allocated overhead including facilities and information technology expenses, and travel associated with our commercial organization. Also included are costs associated with advertising programs that consist of brand and product awareness activities and trade events and conferences. Sales and marketing expense also includes amortization of the trade name intangible asset that was recognized upon the Acquisition, which has been recorded in our financial statements as a result of the application of pushdown accounting. The cost of identifiable intangible assets with finite lives, such as trade names, are amortized on a straight-line basis over the assets' respective estimated useful lives of 9 years. We expect our sales and marketing expenses to increase following the release of positive study results as we invest in initiatives to drive awareness and demand generation of Galleri and to continue to decrease as a percentage of revenue over the next three years and long term.

*General and Administrative* 

General and administrative expenses consist of personnel expenses, including salaries, benefits and stock-based compensation expenses, for executive, finance and accounting, legal, human resources, business development, corporate communications, portfolio management, medical affairs, and management information systems personnel. Also included are professional fees, legal costs, including patent and trademark-related expenses and educational activities. We have incurred and will incur additional expenses as a result of operating as a public company, including expenses related to compliance with the rules and regulations of the SEC, director and officer insurance premiums, investor relations activities, and other expenses related to administrative and professional services. We expect our G&A expenses to increase as we continue to invest in corporate infrastructure to support public company operations and the commercialization of Galleri and to continue to decrease as a percentage of revenue over the next three years and long term.

*Interest Income*

Interest income consists primarily of interest income earned on our cash, cash equivalents, and short-term marketable securities.

------

*Other Income (Expense), Net*

Other income (expense), net primarily consists of foreign currency gains and losses as a result of our intercompany agreements.

*Benefit from Income Taxes*

Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences of events that have been included in the consolidated financial statements. Deferred tax assets are recognized for deductible temporary differences and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portions or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

| Screening revenue | $39832 | $29133 | 37% |
| Development services revenue | $953 | $2704 | (65%) |

---

*Screening Revenue*

The increase in screening revenue of $10.7 million or 37% was primarily driven by a 50% increase in Galleri sales volume, partially offset by a 9% decrease in ASP. Galleri sales volume increased in the first three months of 2026 as a result of the continued ramp in our commercial activity following the release of the PATHFINDER 2 and SYMPLIFY positive study results, implementation of new pricing strategies, increased adoption of enhanced ordering pathways enabled by EHR integrations, expansion of our partnerships with digital health platforms, and increased enrollment in our REACH/Galleri-Medicare clinical study, alongside growth in orders within the employer channel and self-pay patients driven by rising awareness of early cancer detection.

*Development Services Revenue*

The decrease in development services revenue of $1.8 million or 65% was primarily driven by a $1.4 million decrease in revenue from pilots with biopharmaceutical partners and a $0.4 million decrease in revenue from clinical development and research services.

*Cost of Screening Revenue (Exclusive of Amortization of Intangible Assets)*

| Cost of screening revenue (exclusive of amortization of intangible assets) | $21244 | $17123 | 24% |

---

The increase in cost of screening revenue (exclusive of amortization of intangible assets) of $4.1 million or 24% was primarily driven by a 50% increase in Galleri sales volume, partially offset by improved fixed cost leverage due to the increase in volumes, and a decrease in sample reprocessing costs.

Cost of screening revenue (exclusive of amortization of intangible assets) as a percent of revenue decreased 5% in the first three months of 2026 mainly due to improved fixed cost leverage due to the increase in volumes, and a decrease in sample reprocessing costs, partially offset by a 9% decrease in ASP.

*Cost of Development Services Revenue*

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Change** |
| (in thousands) | **March 31,<br>2026** | **March 31,<br>2025** | $**%** |
| Cost of Development Services Revenue | $376 | $1171 | (68)% |

---

The decrease in cost of development services revenue of $0.8 million or 68% was primarily due to a decrease in pilots with biopharmaceutical partners and a decrease in the number of research samples processed.

*Research and Development* 

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Change** |
| (in thousands) | **March 31,<br>2026** | **March 31,<br>2025** | $**%** |
| Research and development | 48021 | 53625 | (10)% |

---

The decrease in research and development expenses of $5.6 million or 10% was primarily attributable to a $2.8 million reduction in compensation expenses, driven by reduced headcount, a $2.4 million reduction in laboratory supplies and research collaboration expenses primarily due to lower research sample volumes as a result of validation samples run in the prior year to support our Premarket Approval ("PMA") submission, and a $1.0 million decrease in allocated information technology expenses primarily related to ongoing cost reduction efforts and a change in mix between research and development and commercial samples, as well as reduced headcount within the research and development function. These decreases were partially offset by a $0.7 million increase in stock-based compensation expense primarily due to new equity grants.

*Sales and Marketing*

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Change** |
| (in thousands) | **March 31,<br>2026** | **March 31,<br>2025** | $**%** |
| Sales and marketing | $30668 | $34979 | (12)% |

---

The decrease in sales and marketing expenses of $4.3 million or 12% was primarily attributable to a $3.7 million decrease in non-recurring marketing event expenses and a $0.7 million decrease in compensation expenses, driven by reduced headcount.

*General and Administrative*

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Change** |

| General and administrative | $42769 | $45074 | (5%) |

---

The decrease in general and administrative expenses of $2.3 million or 5% was primarily attributable to a $3.5 million decrease in legal and professional services expenses and a $1.4 million decrease in costs associated with the use of contractors and temporary labor, both driven by cost optimization efforts. These decreases were partially offset by a $2.3 million increase in compensation expenses, due to annual wage adjustments and non-recurring bonuses.

| Interest income | $7986 | $7779 | 3% |

---

The increase in interest income of $0.2 million or 3% was primarily due to a $147.7 million increase in average balances in money market funds and short-term marketable securities, partially offset by decreases in average rates of return.

*Benefit from Income Taxes*

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Change** |

| Benefit from income taxes | $34336 | $40199 | (15%) |

---

The decrease in benefit from income taxes was primarily driven by a decrease in our loss before taxes and a lower effective tax rate primarily due to fewer discrete tax items related to stock-based compensation expenses.

**Non-GAAP Financial Measures and Royalty Payment Suspension**

In addition to the results provided throughout this Form 10-Q that are determined in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), this Form 10-Q also includes non-GAAP financial measures for the three months ended March 31, 2026 and March 31, 2025. This information should be read in conjunction with our unaudited Condensed Consolidated Financial Statements and the related notes included elsewhere in this Form 10-Q.

The non-GAAP financial measures, definitions, and explanations to the adjustments to comparable GAAP measures are included below:

***Adjusted Gross Profit***

Adjusted Gross Profit is a key performance measure that our management uses to assess our operational performance, as it represents the results of revenues and direct costs, which are key components of our operations. We believe that this non-GAAP financial measure is useful to investors and other interested parties in analyzing our financial performance because it reflects the gross profitability of our operations, and excludes the costs associated with our sales and marketing, product development, general and administrative activities and the impact of our financing methods and income taxes.

We calculate Adjusted Gross Profit as gross profit/(loss) (as defined below) adjusted to exclude amortization of intangible assets and stock-based compensation allocated to cost of revenue. Adjusted Gross Profit should be viewed as a measure of operating performance that is a supplement to, and not a substitute for, operating income or loss from operations, net earnings or loss and other GAAP measures of income (loss) or profitability. The following table presents a reconciliation of gross loss, the most directly comparable financial measure calculated in accordance with GAAP, to Adjusted Gross Profit.

------

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| (in thousands) | **March 31, 2026** <sup>(2)</sup> | **March 31,<br>2025** |
| **Gross loss** <sup>(1)</sup> | $(14307) | $(19929) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Amortization of intangible assets | 33472 | 33472 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Stock-based compensation | 533 | 762 |
| **Adjusted Gross Profit** | $19698 | $14305 |

---

<sup>(1)</sup> Gross loss is calculated as total revenue less cost of screening revenue (exclusive of amortization of intangible assets), cost of &nbsp;&nbsp;&nbsp;&nbsp;development services revenue and cost of revenue — amortization of intangible assets.

<sup>(2)</sup> Gross loss excludes $2.9 million of royalty expense, calculated in accordance with the Illumina Supply Agreement, that would have been incurred if such royalties had been payable during the first quarter of 2026.

***Adjusted EBITDA***

Adjusted EBITDA is a key performance measure that our management uses to assess our financial performance and is also used for internal planning and forecasting purposes. We believe that this non-GAAP financial measure is useful to investors and other interested parties in analyzing our financial performance because it provides a comparable overview of our operations across historical periods. In addition, we believe that providing Adjusted EBITDA, together with a reconciliation of net loss to Adjusted EBITDA, helps investors make comparisons between our company and other companies that may have different capital structures, different tax rates, different operational and ownership histories, and/or different forms of employee compensation.

Adjusted EBITDA is used by our management team as an additional measure of our performance for purposes of business decision-making, including managing expenditures. Period-to-period comparisons of Adjusted EBITDA help our management identify additional trends in our financial results that may not be shown solely by period-to-period comparisons of net income (loss) or income (loss) from operations. Our management recognizes that Adjusted EBITDA has inherent limitations because of the excluded items, and may not be directly comparable to similarly titled metrics used by other companies.

The Company defines Adjusted EBITDA as net loss adjusted for amortization of intangible assets, &nbsp;&nbsp;&nbsp;&nbsp; stock-based compensation, depreciation, benefit from income taxes, interest income and restructuring expenses. These adjustments include non-cash items, significant non-recurring charges and/or other non-operating expenses that we do not believe are indicative of ongoing or future business operations.

------

Adjusted EBITDA should be viewed as a measure of operating performance that is a supplement to, and not a substitute for, operating income or loss from operations, net earnings or loss and other U.S. GAAP measures of income (loss). Additionally, it is not intended to be a measure of free cash flow for management's discretionary use, as it does not consider certain cash requirements such as interest and tax payments. Further, our definition of Adjusted EBITDA may differ from similarly titled measures used by other companies and therefore may not be comparable among companies. The following table presents a reconciliation of net loss, the most directly comparable financial measure calculated in accordance with U.S. GAAP, to Adjusted EBITDA on a consolidated basis.

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Amortization of intangible assets <sup>(1)</sup>  | 34584 | 34584 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Stock-based compensation | 16793 | 16211 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Depreciation | 4210 | 4695 |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Restructuring |  | (34) |
| **Adjusted EBITDA** | $(79922) | $(98735) |

---

<sup>(1)</sup> Represents amortization of intangible assets, including developed technology and trade names.

***Royalty Payment Suspension***

In addition to providing non-GAAP financial measures, we believe certain additional information relating to the royalty we are required to pay to Illumina in the future is useful to investors to understand the impact of the royalty suspension on our performance. Under the terms of the Illumina Supply Agreement, regardless of whether our products incorporate any Illumina technology, we will be obligated to pay Illumina a royalty. We expect that the royalty payments we will make to Illumina in the foreseeable future will result in a 7% royalty rate. The royalty obligation is currently suspended until December 24, 2026 or any earlier change of control of GRAIL, at which time royalty payments to Illumina will resume, without retroactive effect. Notwithstanding the suspension of the royalty, had we been required to pay the royalty to Illumina for the three month period ended March 31, 2026, we would have made payments of $2.9 million. Refer to *Note 10 — Related Party Transactions* for further details.

------

**Liquidity and Capital Resources**

***Sources of Liquidity***

From inception through Illumina's acquisition of GRAIL, we funded operations primarily through the issuance of redeemable convertible preferred stock. Following the acquisition and until completion of the Spin-Off, we received quarterly funding from Illumina. Subsequent to the Spin-Off, we have primarily funded our operations through the sale of common stock and prefunded warrants, as well as generation of revenue from commercial activities. Although we generate revenue from screening and development services, such revenues have not been sufficient to fund our operations.

During 2025, we raised capital through equity financing, including a private investment in public equity ("PIPE") and sales under an at-the-market ("ATM") program, generating aggregate net proceeds of $418.8 million. As of March 31, 2026, $189.3 million worth of shares of common stock remained available for issuance under the ATM program.

As of March 31, 2026, our cash and cash equivalents totaled $69.3 million and our short-term marketable securities totaled $753.8 million.

In October 2025, we signed the Samsung Stock Purchase Agreement providing for the purchase by the Samsung Investors of 1,570,308 shares for aggregated net proceeds of $110.0 million, excluding any issuance costs. The Samsung Investment has not closed, and remains subject to the satisfaction of certain closing conditions set forth in the Samsung Stock Purchase Agreement, including, but not limited to the satisfaction of certain regulatory approvals or clearances, including with respect to the Committee on Foreign Investment in the United States.

***Future Funding Requirements***

We began generating revenue in mid-2021, but we have continued to incur significant losses and negative cash flows from operations. Subsequent to the acquisition of GRAIL by Illumina, we have incurred net losses of $10.3 billion which includes cumulative charges of $7.5 billion for impairment of goodwill and intangible assets and amortization of intangible assets. We expect to continue to incur operating losses over at least the next several years as we continue to invest in research and development and seek to achieve broad reimbursement of our current commercialized products. We believe that our existing cash, cash equivalents and short-term marketable securities will be sufficient to meet our working capital and capital expenditure needs into 2030, as of the date of this Form 10-Q. However, we anticipate that we will need to raise additional financing in the future to fund our operations. Our future capital requirements will depend on many factors, including the timing and extent of spending to support commercialization and pipeline product development, market acceptance of our products prior to broad reimbursement, and the timing of broad reimbursement. We are subject to typical risks associated with an early-stage commercial company and are developing the market for multi-cancer early detection. We may encounter complications with executing our business plans that may cause unforeseen expenses and adversely affect our business.

We may in the future enter into arrangements to acquire or invest in complementary businesses, services, technologies, and intellectual property rights. We may be required to seek additional capital through equity or debt financing. In the event that additional financing is required, we may not be able to raise it on terms acceptable to us or at all. If we raise additional funds through the issuance of additional debt or equity securities, it could result in dilution to our existing stockholders, increased fixed payment obligations, and the existence of securities with rights that may be senior to those of our common stock. If we incur indebtedness, we could become subject to covenants that would restrict our operations. Until June 25, 2026, we are also restricted in our ability to raise money through certain transactions or with certain parties pursuant to the terms of the Tax Matters Agreement we entered into with Illumina on June 21, 2024 in connection with the Spin-Off. We may also choose to raise funds through collaborations and licensing arrangements, in which case we may relinquish significant rights or grant licenses on terms that are not favorable to us. If we are unable to raise additional capital when desired, our business, results of operations, and financial condition would be adversely affected.

------

The following table summarizes our cash flows for the periods presented:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| (in thousands) | **March 31,<br>2026** | **March 31,<br>2025** |
| Net cash used in operating activities | $(86989) | $(95012) |
| Net cash (used in) provided by investing activities | (93438) | 14611 |
| Effect of exchange rate changes on cash, cash equivalents, and restricted cash | 44 | 62 |
| **Net decrease in cash, cash equivalents, and restricted cash** | $(180383) | $(80339) |

---

Generally, our net cash provided by financing activities is used to fund our day to day operating activities. First quarter operating cash requirements are generally higher due to payment in the first quarter of our annual bonuses accrued during the prior year. During the three months ended March 31, 2026 and March 31, 2025, $23.4 million and $24.2 million was paid out related to annual bonuses.

***Net Cash Used in Operating Activities***

The decrease in net cash used in operating activities was primarily driven by a reduction in the net loss, adjusted for non-cash charges of $4.7 million, partially offset by working capital changes of $9.7 million. The improvement in operating cash flow was primarily attributable to increased revenue collections and lower operating expenses, including decreases in marketing expenses, legal and professional services, and costs associated with contractors and temporary labor, driven by cost optimization efforts, as well as lower compensation expenses reflecting a reduction in headcount.

***Net Cash Used in Investing Activities***

The change in net cash used in investing activities was primarily related to the purchase of marketable securities, net of proceeds from maturities of marketable securities.

**Material Cash Requirements**

There have been no material changes to our material cash requirements from those disclosed in our 2025 Form 10-K. Refer to Notes 9 and 10 to our Consolidated Financial Statements of our 2025 Form 10-K for a discussion of our operating lease obligations and purchase commitments.

**Critical Accounting Estimates**

There have been no material changes to our critical accounting estimates during the three months ended March 31, 2026. For a complete discussion of our critical accounting estimates, refer to the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of the 2025 Form 10-K.

------

**JOBS Act**

We are an emerging growth company ("EGC") under the Jumpstart our Business Startups Act of 2012 (the "JOBS Act"). As an emerging growth company, we may delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have nonetheless irrevocably elected not to avail ourselves of this exemption and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

We will remain an EGC until the earliest to occur of the following: (i) the last day of the fiscal year in which our total annual gross revenues first meet or exceed at least $1.235 billion (as adjusted for inflation), (ii) the date on which we have, during the prior three-year period, issued more than $1.0 billion in non-convertible debt, (iii) the last day of the fiscal year in which we (a) have an aggregate worldwide market value of common stock held by non-affiliates of $700 million or more (measured at the end of each fiscal year) as of the last business day of our most recently completed second fiscal quarter and (b) have been a reporting company under the Exchange Act for at least one year (and have filed at least one annual report under the Exchange Act and are not smaller reporting company), or (iv) the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common stock pursuant to an effective registration statement under the Securities Act. We expect to cease to be an EGC effective December 31, 2026.

**Recent Accounting Pronouncements**

See *Note 2 — Summary Of Significant Accounting Policies* to our unaudited Condensed Consolidated Financial Statements included in *Item 1. Financial Statements* for details of recent accounting pronouncements.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

***Interest Rate Sensitivity***

We are exposed to market risk related to changes in interest rates related primarily to our cash, cash equivalents and marketable securities. We had cash and cash equivalents of $69.3 million as of March 31, 2026, which consisted primarily of bank deposits, money market funds and marketable securities. As of March 31, 2026, we had short-term marketable securities of $753.8 million. Our marketable securities are held in U.S. government treasury bills. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of the interest rates in the United States. The primary objective of our investment activities is to preserve capital to fund our operations. We do not enter into investments for trading or speculative purposes.

Our investments are subject to interest rate risk and could fall in value if market interest rates increase. Due to the short-term duration of our investment portfolio and the low-risk profile of our investments, a hypothetical 10% relative change in interest rates during any of the periods presented would not have had a material impact on our Condensed Consolidated Financial Statements.

***Foreign Currency Sensitivity***

The majority of our transactions occur in U.S. dollars. However, we do have certain transactions that are denominated in currencies other than the U.S. dollar, primarily the British pound, and we therefore are subject to foreign exchange risk. The fluctuation in the value of the U.S. dollar against the foreign currencies affects the reported amounts of expenses, assets, and liabilities associated with certain activities. We do not currently engage in any hedging activity to reduce our potential exposure to currency fluctuations, although we may choose to do so in the future. A hypothetical 10% change in foreign exchange rates during any of the periods presented would not have had a material impact on our Condensed Consolidated Financial Statements.

**Item 4. Controls and Procedures**

***Limitation on Effectiveness of Controls and Procedures***

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect

------

the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

***Evaluation of Disclosure Controls and Procedures***

Our management, with the participation of our principal executive officer and principal financial officer, evaluated, as of the end of the period covered by this Form 10-Q, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our principal executive officer and principal financial officer concluded that, as of March 31, 2026, our disclosure controls and procedures were effective at the reasonable assurance level.

**C*hanges in Internal Control over Financial Reporting***

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

------

**Part II - Other Information**

**Item 1. Legal Proceedings**

For information with respect to Legal Proceedings, see *Note 6 — Legal Proceedings, Commitments, and Contingencies* to our condensed consolidated financial statements included in this Form 10-Q.

**Item 1A. Risk Factors** 

Our business, financial condition and operating results are affected by a number of factors, whether currently known or unknown, including risks specific to us or the healthcare industry as well as risks that affect businesses in general. In addition to the information set forth in this Form 10-Q, you should consider carefully the factors discussed in Part I, Item 1A, "Risk Factors" in our 2025 Form 10-K (filed with the SEC on March 12, 2026). The risks and uncertainties disclosed in such Annual Report and in this Form 10-Q could materially adversely affect our business, financial condition, cash flows or results of operations and thus our stock price. During the first quarter of fiscal year 2026, there were no material changes to our previously disclosed risk factors.

These risk factors may be important to understanding other statements in this Form 10-Q and should be read in conjunction with the unaudited condensed consolidated financial statements and related notes in Part I, Item 1, "Financial Statements" and Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Form 10-Q. Because of such risk factors, as well as other factors affecting our financial condition and operating results, past financial performance should not be considered to be a reliable indicator of future performance, and investors should not use historical trends to anticipate results or trends in future periods.
