Strategic Objectives

Our 2026 main objectives are to grow revenue and expand gross margins through the following five activities. These initiatives are designed to improve the economics of HiFi sequencing, expand adoption across clinical and research markets, and drive durable growth across our platform portfolio.

•Accelerate samples onto the Revio platform through SPRQ-Nx chemistry and application kits. SPRQ-Nx is designed to lower the cost of sequencing and improve sequencing efficiency, which we believe will support higher throughput, increased sample volumes, and broader adoption of HiFi sequencing in large-scale research studies and clinical applications.

•Expand the capabilities of the Vega benchtop platform to broaden our market reach. We plan to enable faster run times and enhanced user experience through software improvements, which are intended to support broader adoption and improve the overall economics of HiFi sequencing.

•Progress our clinical strategy to improve outcomes and create durability. Revio is increasingly being adopted in laboratory-developed test ("LDT") and clinical research settings, supporting consolidation of multiple tests, addressing complex genetic challenges, and driving sustained utilization of HiFi sequencing. This includes in the Americas, where we continue to aggressively shift our strategy to clinical and commercial accounts where we believe the funding dynamics are more favorable.

•Advance data-driven interpretation through scalable HiFi datasets and analytics. We are focused on leveraging the accuracy of HiFi sequencing and growing datasets to support advanced data analysis and AI-assisted interpretation approaches. Collaborative initiatives such as the HiFi Solves Global Consortium are designed to aggregate large, well-characterized HiFi datasets, which we believe can support improved understanding of complex genetic variation and disease biology while maintaining expert oversight.

•Invest in future product launches to drive platform innovation. We continue to develop sequencing solutions designed to increase throughput, simplify workflows, lower the cost to sequence a genome, and enhance downstream data analysis and interpretation capabilities, which we believe will allow us to address a larger portion of the market.

We continue to believe that with the capabilities of our technology, we can be a market leader in whole-genome clinical sequencing. Leading institutions have adopted our products to study rare and inherited disease. We believe the market opportunity for clinical sequencing is significant and could drive substantial revenue growth for the Company. We plan to continue to pursue partner collaborations where the technologies being developed or applications being considered extend beyond whole-genome clinical sequencing. Collaborative arrangements add to the awareness of our products and service offerings and may drive new applications for use of our technology.

Financial Overview

Key highlights of the three months ended March 31, 2026 consolidated financial results include the following:

Revenue of

Gross profit of

Operating loss of

Cash, cash equivalents, and investments of

$37.2 M

$12.8 M

$8.4 M

$276.0 M

compared to $37.2 M during the same period of 2025

compared to gross loss of $1.4 M during the same period of 2025

compared to $428.9 M during the same period of 2025

compared to $279.5 M at December 31, 2025

•Revenue was comprised of $9.7 million in instrument revenue, $21.8 million in consumables revenue and $5.6 million in service and other revenue during the three months ended March 31, 2026. Revenue was comprised of $11.0 million in instrument revenue, $20.1 million in consumables revenue and $6.0 million in service and other revenue during the three months ended March 31, 2025. An increase in Consumable revenue and higher Revio unit sales were offset by lower Vega unit sales and a decrease in service and other revenue.

•We recorded a gross profit of $12.8 million during the three months ended March 31, 2026 compared to a gross loss of $1.4 million during the same period of 2025. We recorded approximately $12.0 million of restructuring charges during the three months ended March 31, 2025. See Note 5. Restructuring in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information. Gross margins may be affected by product mix, manufacturing efficiencies, changes in warranty costs, average selling price fluctuations, product promotions, future product launches, changes to inventory reserves, costs of raw materials, computing costs, specifically memory, and tariffs.

•Loss from operations decreased $420.6 million during the three months ended March 31, 2026, compared with the same period of 2025, primarily due to a $406.4 million decrease in operating expenses. Operating expenses of $21.2 million for the three months ended March 31, 2026 included litigation settlement expenses of $15.4 million. Operating expenses were mostly offset by a $45.8 million gain on disposal of assets to Illumina Cambridge Limited due to the Asset Sale. See Note 2. Financial Instruments in Part I, Item I of this Quarterly Report on Form 10-Q for more information. Operating expenses of $427.6 million during the three months ended March 31, 2025 included $381.8 million of costs incurred in connection with the restructuring and strategic shift, which included $359.3 million of accelerated amortization of acquired intangibles, $15.0 million of impairment charges, and $4.6 million of employee separation costs, partially offset by an $18.7 million decrease in the change in the fair value of the contingent consideration.

•Cash, cash equivalents, and short-term investments were $276.0 million at March 31, 2026, which represents a 1% decrease compared to the balance at December 31, 2025. During the three months ended March 31, 2026 we received net cash proceeds of approximately $48.1 million in conjunction with the gain on disposal of assets discussed above.

We believe that demand for our instruments (particularly Vega) remains constrained due to, among other reasons, the funding environment in the United States, contributing to elongated sales cycles, or in certain cases, customers not placing instrument orders. Additionally, sales cycles have been and continue to be impacted by, among other reasons, continued capital funding constraints in academic and research markets, procurement timing considerations, and longer adoption cycles among new customers, which have affected the timing of certain instrument orders. We believe these challenges will impact second quarter 2026 revenue with approximately single-digit to low double-digit sequential revenue growth. However, we believe that revenues will be greater in the back half of 2026, which we expect will be driven by continued clinical adoption, SPRQ-Nx consumable growth, and revenue associated with the Basecamp Research program, which we believe will start to materialize in the second and third quarters of 2026. We are continuing development of a high-throughput, HiFi sequencer, which we believe could launch in 2027.

Macroeconomic dynamics that have impacted and could continue to impact the Company include rising inflation, higher computing component costs, specifically memory, which may result in material cost pressures and supply constraints in future periods, geopolitical tensions, including recent conflicts in the Middle East (including Iran), volatile capital markets, tariffs, uncertainty in the United States related to NIH and academic funding, and fluctuating exchange rates. These factors could continue to impact our revenues and results of

operations in future periods; however, the magnitude and duration of these impacts is highly uncertain and inherently unpredictable.

On an ongoing basis, we evaluate our significant estimates, including those related to the valuation of goodwill, indefinite-lived and finite-lived assets. However, these estimates could change in future periods based on events or changes in circumstances, which could result in material future impairment charges. We recorded $15.0 million of impairment charges during the three months ended March 31, 2025. See additional discussion below in Results of Operations, as well as Note 3. Balance Sheet Components in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information.

OVERVIEW AND OUTLOOK

About PacBio

We are a premier life science technology company that designs, develops, and manufactures advanced sequencing solutions that enable scientists and clinical researchers to improve their understanding of the genome and ultimately, resolve genetically complex problems.

Our products and technology, which include our HiFi long-read sequencing technology, address a broad set of applications including human germline sequencing, plant and animal sciences, infectious disease and microbiology, oncology, and other emerging applications.

Our focus is on creating some of the world’s most advanced sequencing systems to provide our customers with the most complete and accurate view of genomes, transcriptomes, and epigenomes.

Our customers include academic and governmental research institutions, commercial testing and service laboratories, genome centers, public health labs, hospitals and clinical research institutes, CROs, pharmaceutical companies, and agricultural companies.

Recent Developments

On January 30, 2026, we completed a disposition of assets to Buyer in accordance with the terms of the Asset Purchase Agreement, pursuant to which, among other matters, Buyer acquired certain intellectual property and other assets related to our short-read DNA sequencing technology and related clustering, sequencing reagent, and detection technologies. As consideration for the Asset Sale, Buyer paid us $50.0 million in cash and assumed certain liabilities. In addition, Buyer granted us a non-exclusive license to certain intellectual property included in the purchased assets. In connection with the Asset Sale, Buyer will pay at our direction 4% of the net proceeds from the Purchase Price to the former equity holders of Apton related to the waiver of all remaining milestone obligations associated with our purchase of Apton in August 2023, which payment is expected in the first quarter of 2026. As a result, we received approximately $48.1 million in net cash proceeds from the Asset Sale.

Strategic Objectives

Looking ahead to 2026, our main objectives are to grow revenue and expand gross margins through the following five activities. These initiatives are designed to improve the economics of HiFi sequencing, expand adoption across clinical and research markets, and drive durable growth across our platform portfolio.

•Accelerate samples onto the Revio platform through SPRQ-Nx chemistry and application kits. SPRQ-Nx is designed to lower the cost of sequencing and improve sequencing efficiency, which we believe will support higher throughput, increased sample volumes, and broader adoption of HiFi sequencing in large-scale research studies and clinical applications.

•Expand the capabilities of the Vega benchtop platform to broaden our market reach. We plan to enable faster run times and enhanced user experience through software improvements, which are intended to support broader adoption and improve the overall economics of HiFi sequencing.

•Progress our clinical strategy to improve outcomes and create durability. Revio is increasingly being adopted in laboratory-developed test ("LDT") and clinical research settings, supporting consolidation of multiple tests, addressing complex genetic challenges, and driving sustained utilization of HiFi sequencing.

•Advance data-driven interpretation through scalable HiFi datasets and analytics. We are focused on leveraging the accuracy of HiFi sequencing and growing datasets to support advanced data analysis and AI-assisted interpretation approaches. Collaborative initiatives such as the HiFi Solves Global Consortium are designed to aggregate large, well-characterized HiFi datasets, which we believe can support improved understanding of complex genetic variation and disease biology while maintaining expert oversight.

•Invest in future product launches to drive platform innovation. We continue to develop sequencing solutions designed to increase throughput, simplify workflows, lower the cost to sequence a genome, and enhance downstream data analysis and interpretation capabilities, which we believe will allow us to address a larger portion of the market.

We continue to believe that with the capabilities of our technology, we can be a market leader in whole-genome clinical sequencing. Leading institutions have adopted our products to study rare and inherited disease. We believe the market opportunity for clinical sequencing is significant and could drive substantial revenue growth for the company. We plan to continue to pursue partner collaborations where the technologies being developed or applications being considered extend beyond whole-genome clinical sequencing. Collaborative arrangements add to the awareness of our products and service offerings and may drive new applications for use of our technology.

Financial Overview

•Revenue was comprised of approximately $82.0 million in consumables revenue, $53.8 million in instrument revenue, and $24.2 million in service and other revenue for the year ended December 31, 2025. Revenue was comprised $70.3 million in consumables revenue, $65.8 million in instrument revenue, and $17.9 million in service and other revenue for the year ended December 31, 2024. The increase in total revenue was primarily due to higher consumable sales, Vega instrument sales, and

Fiscal 2025 Form 10-K

Table of Contents

service and other revenue, partially offset by lower Revio instrument sales as compared to the prior year.

•Gross profit increased for the year ended December 31, 2025 compared to the year ended December 31, 2024. The increase was primarily driven by higher consumable volumes, which drove a more favorable product mix. Gross margins may be affected by product mix, manufacturing efficiencies, changes in warranty costs, average selling price fluctuations, future product launches, changes to inventory reserves, costs of raw materials, and tariffs.

•Loss from operations increased for the year ended December 31, 2025 compared to the year ended December 31, 2024 primarily due to $383.1 million of restructuring-related costs. See Note 6. Restructuring in Part II, Item 8 of this Annual Report on Form 10-K for additional information about restructuring activities. These restructuring-related costs were partially offset by a $169.5 million decrease in impairment charges and a $17.9 million change in fair value of contingent consideration. As a result of the restructuring, core operating expenses, consisting of research and development and sales, general and administrative expenses, decreased by $71.1 million.

•Cash, cash equivalents, and investments were $279.5 million at December 31, 2025, which represents a 28% decrease compared to the balance of $389.9 million at December 31, 2024.

We believe that our sales cycles for Revio instruments continues to be elongated due to, among other reasons, continued capital funding constraints in academic and research markets, procurement timing considerations, and longer adoption cycles among new customers, which have affected the timing of certain instrument orders.

Macroeconomic dynamics impacting the Company in the future may include rising inflation, geopolitical tensions, volatile capital markets, tariffs, uncertainty in the United States related to NIH and academic funding, and fluctuating exchange rates. These factors could continue to impact our revenues and results of operations in future periods; however, the magnitude and duration of these impacts is highly uncertain and inherently unpredictable.

On an ongoing basis, we evaluate our significant estimates, including those related to the valuation of goodwill, indefinite-lived and finite-lived assets. However, these estimates could change in future periods based on events or changes in circumstances, which could result in material future impairment charges. We recorded $15.0 million of impairment charges during the first quarter of 2025. See additional discussion below in Results of Operations, as well as Note 4. Balance Sheet Components in Part II, Item 8 of this Annual Report on Form 10-K for further information. Additionally, refer to the Critical Accounting Policies and Estimates section later in this Item 7 for further discussion on the Company's asset impairment assessments.

Revenue

Total Revenue

Total revenue increased $6.0 million for the year ended December 31, 2025, as compared to the year ended December 31, 2024.

Product revenue decreased slightly compared to prior year. Instrument revenue decreased $12.0 million, or 18% and consumables revenue increased $11.6 million, or 16%.

Service and other revenue increased $6.4 million, or 36%, primarily driven by an increase in Revio service contracts.

Consumables Revenue

The increase in consumables revenue for the year ended December 31, 2025 as compared to the year ended December 31, 2024 was primarily driven by higher Revio consumables sales, reflecting the continued expansion of the Revio instrument installed base.

Looking ahead, we expect consumables revenue to increase as we execute against our strategic objectives and expand utilization of our sequencing platforms. This growth is expected to be driven by a growing installed base of Revio and Vega instruments, enhancing platform economics that support higher throughput, and broader adoption across research and clinical research applications. In addition, continued investments in chemistry, application kits, and workflow enhancements are intended to expand addressable applications and increase consumables usage per instrument over time.

Instrument Revenue

Instrument revenue decreased for the year ended December 31, 2025 compared to the year ended December 31, 2024 primarily due to a lower number of Revio systems sold—61 units during the year ended December 31, 2025 compared to 97 Revio systems during the year ended December 31, 2024. This decline primarily reflects variability in customer purchasing behavior resulting from uncertainty surrounding the funding for new capital equipment, particularly among academic and research institutions.

The decrease was partially offset by sales of Vega systems, with 140 units sold during the year ended December 31, 2025 following its commercial launch in the fourth quarter of 2024.

We expect that instrument revenue may fluctuate based on timing of customer purchasing decisions, sales mix, and funding dynamics.

Table of Contents

Cost of Revenue and Gross Profit

Total cost of revenue decreased $2.5 million, or 2%, during the year ended December 31, 2025, compared to the year ended December 31, 2024 primarily due to more favorable product mix driven by higher consumable sales and a decrease in amortization of acquired intangible assets. These decreases were partially offset by $8.1 million of excess inventory charges resulting from reduced external demand and $3.9 million of estimated losses on purchase commitments associated with anticipated excess inventory in connection with the Company’s expense reduction and strategic initiatives. Excess inventory charges were $3.6 million for the year ended December 31, 2024. Total cost of revenue included share-based compensation expense of $3.8 million and $5.7 million during the years ended December 31, 2025 and 2024, respectively.

Gross profit increased $8.5 million, or 23%, for the year ended December 31, 2025, compared to the year ended December 31, 2024 driven by higher consumable volumes and the resulting improvement in product mix, partially offset by restructuring-related charges. See Note 6. Restructuring in Part II, Item 8 of this Annual Report on Form 10-K for additional information about restructuring activities. Gross margins may be affected by product mix, manufacturing efficiencies, changes in warranty costs, average selling price fluctuations, future product launches, changes to inventory reserves, costs of raw materials and tariffs.

Research and Development Expense

Research and development expense decreased by $37.6 million, or 28%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The decrease was primarily driven by a decrease in personnel and related expenses, including share-based compensation expense, lower product development costs due to the transition of launched products from development to commercialization, and lower restructuring-related charges, partially offset by an increase in future product development activities. We recorded $2.8 million of restructuring-related charges during the year ended December 31, 2025 compared to $5.9 million for the year ended December 31, 2024. Research and development expense included share-based compensation of $11.2 million and $19.2 million during the years ended December 31, 2025 and 2024, respectively.

Sales, General, and Administrative Expense

Sales, general and administrative expense decreased by $33.5 million, or 19%, during the year ended December 31, 2025, compared to the year ended December 31, 2024. The decrease was primarily due to a decrease in personnel and related expenses, including share-based compensation expense, and lower restructuring-related charges. We recorded $6.1 million of restructuring-related charges during the year ended December 31, 2025 compared to $14.9 million for the year ended December 31, 2024. Sales, general, and administrative expense included share-based compensation expenses of $26.6 million and $46.2 million during the years ended December 31, 2025 and 2024, respectively.

Impairment Charges

We recorded impairment charges of $15.0 million during the first quarter of 2025, related to in-process research and development (“IPR&D”). These charges resulted from an interim impairment assessment performed in response to identified indicators of impairment during the period. The impairment test concluded that the fair value of our IPR&D assets was $0. See Note 4. Balance Sheet Components in Part II, Item 8 of this Annual Report on Form 10-K for further details.

We recorded impairment charges of $184.5 million during the year ended December 31, 2024 including $144.5 million of goodwill and $40.0 million of IPR&D as a result of quantitative interim impairment tests.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets during the year ended December 31, 2025 included $359.3 million of accelerated amortization recorded during the first quarter of 2025 which was related to developed technology from the 2021 Omniome acquisition, reflecting our revised estimate that the asset will no longer generate economic benefit. We expect significantly lower amortization expense in future periods.

Fiscal 2025 Form 10-K

65

Table of Contents

Change in Fair Value of Contingent Consideration

During the first quarter of 2025 we recognized a change in fair value of contingent consideration of $18.7 million, resulting in a contingent consideration liability of $0. This was primarily due to management's decision to cease development of the high-throughput short-read system, the associated changes in expected future revenues, and the requirement that the milestone event occur prior to the five-year anniversary of the acquisition closing date.

On January 30, 2026, we completed a disposition of assets to Buyer in accordance with the terms of the Asset Purchase Agreement. In connection with the Asset Sale, Buyer will pay at our direction 4% of the net proceeds from the Purchase Price to the former equity holders of Apton related to the waiver of all remaining milestone obligations associated with our purchase of Apton in August 2023, which payment is expected in the first quarter of 2026. See Note 12. Subsequent Events in Part II, Item 8 of this Annual Report on Form 10-K for further details.

Gain on Debt Restructuring

Gain on debt restructuring of $154.4 million during the year ended December 31, 2024, represents the gain resulting from the Exchange Transaction, which qualified as a troubled debt restructuring under Accounting Standards Codification ("ASC") 470-60, Debt - Troubled Debt Restructurings by Debtors. Since the undiscounted cash flows of the new 2029 Notes were less than the carrying amount of the exchanged 2028 Notes, the carrying value of the 2029 Notes was determined based on the total undiscounted cash flows. The gain was calculated as the difference between the carrying amount of the old debt and the carrying amount of the new debt, adjusted for debt issuance costs. See Note 5. Convertible Senior Notes in Part II, Item 8 of this Annual Report on Form 10-K for further details.

Interest Expense

Interest expense during the years ended December 31, 2025 and 2024 was primarily comprised of interest on the convertible senior notes. The decrease was due to lower convertible notes balances as a result of the notes exchange transaction in November 2024. See Note 5. Convertible Senior Notes in Part II, Item 8 of this Annual Report on Form 10-K for additional information.

Other Income, Net

The decrease in other income, net was primarily driven by lower investment income due to lower cash and investment balances.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity, other than our holdings of cash, cash equivalents, and investments, has primarily been through the issuance of debt or equity securities, together with cash flow from operating activities. For example, in January 2023, as discussed in Note 9. Stockholders’ Equity in Part II, Item 8 of this Annual Report on Form 10-K, we issued and sold an aggregate of 20,125,000 shares of our common stock in a follow-on public offering for aggregate gross proceeds of approximately $201.3 million. We have historically incurred, and expect to continue to incur, operating losses and generate negative cash flows from operations on an annual basis due to the investments we intend to make as described in Results of Operations above, and as a result, we may require additional capital resources to execute our strategic initiatives to grow our business.

We approved and implemented certain efficiency and expense reduction initiatives during 2025 and 2024. These expense reduction initiatives included workforce reductions, facilities downsizing and a refined pipeline of development programs.

Cash, Cash Equivalents, and Investments

As of December 31, 2025, we had $279.5 million in cash, cash equivalents, and investments, compared to $389.9 million at December 31, 2024. The decrease was primarily attributable to $111.2 million cash used in operating activities during the year ended December 31, 2025.

Convertible Senior Notes

On February 9, 2021, we entered into an investment agreement with SB Northstar LP (“SBN”), a subsidiary of SoftBank Group Corp., relating to the issuance and sale to SBN of $900.0 million in aggregate principal amount of our 2028 Notes. The 2028 Notes were issued on February 16, 2021 and, as of November 21, 2024, no 2028 Notes were outstanding.

In June 2023, we entered into a privately negotiated exchange agreement with a holder of our outstanding 2028 Notes, pursuant to which we issued $441.0 million in aggregate principal amount of our 2030 Notes in exchange for $441.0 million principal amount of the 2028 Notes, leaving approximately $459.0 million in aggregate principal amount outstanding of our 2028 Notes. Interest on the 2030 Notes is payable semi-annually in arrears on June 15 and December 15 commencing on December 15, 2023. The 2030 Notes will mature on December 15, 2030, subject to earlier conversion, redemption, or repurchase.

In November 2024, we entered into an exchange agreement with SBN, pursuant to which we agreed to exchange the remaining approximately $459.0 million in aggregate principal amount of 2028 Notes outstanding for (i) $200.0 million aggregate principal amount of the 2029 Notes, (ii) 20,451,570 shares of common stock (the “Exchange Shares”) and (iii) $50.0 million of cash. The exchange and issuances closed on November 21, 2024 (the “Closing Date”). The 2029 Notes, the Exchange Shares, and shares of common stock issuable upon conversion of the 2029 Notes were subject to certain lock-up restrictions for a six-month period (the “Lock-Up Period”) beginning on the Closing Date of the Exchange Transaction; the lock-up restrictions will terminate immediately prior to the consummation of any change in control of the Company. The 2029 Notes bear interest at a rate of 1.50% per annum. Interest on the 2029 Notes is payable semi-annually in arrears on February 15 and August 15 and commencing on February 15, 2025. The 2029 Notes will mature on August 15, 2029, subject to earlier conversion, redemption or repurchase.

The 2029 Notes are convertible at the option of the holder at any time from the expiration of the Lock-Up Period until the second scheduled trading day prior to the maturity date, including in connection with a redemption by the Company. The 2029 Notes are convertible into shares of our common stock based on an initial conversion rate of 204.5157 shares of common stock per $1,000 principal amount of the 2029 Notes (which is equal to an initial conversion price of approximately $4.89 per share of common stock), in each case subject to customary anti-dilution and other adjustments as a result of certain extraordinary transactions. Upon conversion of the 2029 Notes, we may elect to settle such conversion obligation in shares of our common stock, cash or a combination of shares of our common stock and cash.

The 2030 Notes are convertible at the option of the holder at any time until the second scheduled trading day prior to the maturity date, including in connection with a redemption by the Company. The 2030 Notes are convertible into shares of our common stock based on an initial conversion rate of 46.5116 shares of common stock per $1,000 principal amount of the 2030 Notes (which is equal to an initial conversion price of approximately $21.50 per share of common stock), in each case subject to customary anti-dilution and other adjustments as a result of certain extraordinary transactions. Upon conversion of the 2030 Notes, we may elect to settle such conversion obligation in shares of our common stock, cash or a combination of shares of our common stock and cash.

With certain exceptions, upon a change of control of our company or the failure of our common stock to be listed on certain stock exchanges, the holders of the Notes may require that we repurchase all or part of the principal amount of those Notes at a purchase price of par plus unpaid interest up to, but excluding, the maturity date.

The indenture governing the 2029 Notes and the 2030 Notes include customary “events of default,” which may result in the acceleration of the maturity of the Notes under the respective indentures. The indentures also include customary covenants for convertible notes of this type.

Additionally, on November 21, 2024, in connection with the issuance of the 2029 Notes, the Company and SBN entered into the Letter Agreement pursuant to which the Company and SBN agreed that, for so long as SBN and its affiliates hold at least $180 million aggregate principal amount of the 2029 Notes, the Company and its subsidiaries are subject to certain negative covenants that restrict the Company’s and its subsidiaries’ ability to incur additional indebtedness and create liens, in each case, subject to the exceptions set forth in the Letter Agreement, including exceptions which permit the Company to incur up to $75 million in aggregate principal amount of secured indebtedness pursuant to Credit Facilities (as defined in the Letter Agreement). In addition, the Letter Agreement restricts the ability of the Company and its subsidiaries from guaranteeing any

indebtedness or incurring certain indebtedness outside of the ordinary course of business unless, in each case, the Company and its subsidiaries concurrently provide a guarantee of the Company’s obligations under the 2029 Notes.

See Note 5. Convertible Senior Notes in Part II, Item 8 of this Annual Report on Form 10-K for further details.

Additional Capital Requirements

We believe that our existing cash, cash equivalents, and investments will be sufficient to fund our projected operating and capital requirements for at least the next 12 months from the date of filing of this Annual Report on Form 10-K for the year ended December 31, 2025. Operating needs include planned costs to operate our business, including costs to fund working capital and capital expenditures. Recent and expected working and other capital requirements, in addition to the above matters, include:

•Our purchase orders and contractual obligations of approximately $71.3 million as of December 31, 2025, which consist of open purchase orders and contractual obligations in the ordinary course of business, including commitments with contract manufacturers and suppliers for which we have not received the goods or services. A majority of these purchase obligations are due within a year. Although open purchase orders are considered enforceable and legally binding, the terms generally allow us the option to cancel, reschedule and adjust our requirements based on our business needs prior to the delivery of goods or performance of services.

•As described in Note 7 - Commitments and Contingencies in Part II, Item 8 of this Annual Report on Form 10-K, we have a Supply Agreement, that includes minimum annual purchase commitments for certain products through 2031. To secure supply under the agreement, we paid deposits totaling $15.0 million, of which $4.0 million and $3.0 million were refunded in 2025 and 2024, respectively. The supplier may retain all or a portion of the deposit if we fail to meet our minimum purchase commitments.

•As described in Note 4 - Balance Sheet Components in Part II, Item 8 of this Annual Report on Form 10-K the Company entered into an agreement to acquire certain developed technology and related intellectual property from The Chinese University of Hong Kong for a total consideration of $9.7 million. In addition, the Company entered into a license agreement for complementary developed technology during the three months ended March 31, 2025. Both the acquired technology and license are classified as intangible assets and are being amortized over an estimated useful life of three years. As of December 31, 2025, $5.0 million of these intangible assets remained unpaid. This amount is included in accrued liabilities on the condensed consolidated balance sheets and is expected to be paid in 2026.

•Our research and development expenditures of $97.3 million in 2025 and $134.9 million in 2024. We expect to continue our investment in research and development in 2026, including enhancements of our existing products, and continued development of other new technology and products.

•Cash outflows for capital expenditures of $2.7 million in 2025 and $6.2 million in 2024. We expect to continue to invest in capital expenditures in fiscal 2026 to continue to support manufacturing and expansion of our business.

•Amounts related to future lease payments for operating lease obligations at December 31, 2025, totaling $98.2 million, with $4.0 million expected to be paid within the next 12 months.

•Payments related to licensing and other arrangements, which are cancellable license agreements with third parties for certain patent rights and technology. Under the terms of these agreements, we may be obligated to pay royalties based on revenue from the sales of licensed products, or minimum royalties, whichever is greater, and license maintenance fees. The future license maintenance fees and minimum royalty payments under the license agreements are not deemed to be material.

Our future capital requirements and the adequacy of our available funds will depend on many factors, including:

•our ability to successfully commercialize and develop products and solutions that address customer needs;

•the pace of adoption of our products and our ability to obtain new customers in markets;

•the progress of our research and development programs and our ability to initiate or expand research programs;

•our ability to manage manufacturing and production costs, including purchase obligations, and litigation costs, including the costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and

•the extent to which we engage in collaborations with partners and acquire other businesses or technologies.

If economic, financial, business, or other factors adversely affect our ability to fund our projected operating cash requirements, we may be required to obtain funding through traditional or alternative sources of financing. Raising additional funds may result in dilution to existing shareholders. We cannot be certain that funds will be available on favorable terms, or at all. If we are required and unable to raise additional capital when desired, our business, operating results, and financial condition may be adversely affected. See our risk factor captioned “We are not cash flow positive and may not have sufficient cash to make required payments under the terms of our debt or fund our long-term planned operations” for more information.

Operating Activities

Our primary uses of cash in operating activities include the development of future products and product enhancements, manufacturing, and support functions related to our sales, general, and administrative activities.

Cash used in operating activities for the year ended December 31, 2025, of $111.2 million was due primarily to a $546.4 million net loss that included non-cash items such as impairment charges of $15.0 million, share-based compensation of $41.7 million, amortization of intangible assets of $369.4 million, depreciation of $13.0 million, amortization of right-of-use assets of $4.0 million, and $4.4 million from changes in net operating assets and liabilities primarily driven by a decrease in prepaid expenses and other assets as well as increases in accrued expenses and accounts payable partially offset by increases in accounts receivable and inventory. These changes in non-cash items were partially offset by an $18.7 million decrease in the change in the fair value of the contingent consideration and accretion of discount and amortization of premium on marketable securities, net of $4.4 million.

Cash used in operating activities for the year ended December 31, 2024, of $206.1 million was due primarily to a $309.9 million net loss that included non-cash items such as impairment charges of $184.5 million, share-based compensation of $71.0 million, amortization of intangible assets of $27.4 million, depreciation of $13.8 million, and amortization of right-of-use assets of $12.2 million, offset by a gain on debt restructuring of $154.4 million, and accretion of discount and amortization of premium on marketable securities, net of $13.0 million. Cash flow impact from changes in net operating assets and liabilities of $40.6 million, was primarily driven by an increase of $8.3 million in inventory, net, as well as decreases of $26.3 million in accrued expenses and $11.9 million in operating lease liabilities. These uses of cash were partially offset by a decrease of $9.1 million in accounts receivable, net.

Investing Activities

Our investing activities consist primarily of purchases, sales and maturities of investments as well as capital expenditures.

Cash provided by investing activities for the year ended December 31, 2025, was due primarily to maturities of investments of $340.1 million partially offset by purchases of investments of $216.9 million, $5.0 million in purchases of intangible assets, and capital expenditures of $2.7 million.

Cash provided by investing activities for the year ended December 31, 2024, was due primarily to maturities of investments of $594.0 million partially offset by purchases of investments of $498.6 million and capital expenditures of $6.2 million.

Financing Activities

Cash provided by financing activities during the year ended December 31, 2025 resulted from $3.4 million of proceeds from the issuance of common stock through our equity compensation plans.

Cash used in financing activities during the year ended December 31, 2024, was primarily due to payments made in conjunction with the convertible notes exchange of $50.2 million partially offset by proceeds of $7.7 million from the issuance of common stock through our equity compensation plans.

OFF-BALANCE SHEET ARRANGEMENTS

As of December 31, 2025, we did not have any off-balance sheet arrangements.

In the ordinary course of business, we enter into standard indemnification arrangements. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology, or from claims relating to our performance or non-performance under a contract, any defective products supplied by us, or any acts or omissions, or willful misconduct, committed by us or any of our employees, agents or representatives. The term of these indemnification agreements is generally perpetual after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these agreements is not determinable because it involves claims that may be made against us in future periods but have not yet been made. To date, we have not incurred costs to defend lawsuits or settle claims related to these indemnification agreements.

We also enter and have entered into indemnification agreements with our directors and officers that may require us to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law. In addition, we may have obligations to hold harmless and indemnify third parties involved with our fundraising efforts and their respective affiliates, directors, officers, employees, agents or other representatives against any and all losses, claims, damages and liabilities related to claims arising against such parties pursuant to the terms of agreements entered into between us and such third parties in connection with such fundraising efforts. To the extent that such indemnification obligations apply to the lawsuits described in Legal Proceedings in Part I, Item 3 of this Annual Report on Form 10-K, any associated expenses incurred are included within the related accrued litigation expense amounts. No additional liability associated with such indemnification agreements has been recorded as of December 31, 2025.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our consolidated financial statements, which we have prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, cost of revenue, and operating expenses, and related disclosure of contingent assets and liabilities. Management based its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially 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 likely to occur could materially impact the financial statements.

Revenue Recognition

Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of our instruments and related consumables; service and other revenue consist primarily of revenue earned from product maintenance agreements.

Fiscal 2025 Form 10-K

Table of Contents

We account for a contract with a customer when there is a legally enforceable contract between us and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. Revenues are recognized when control of the promised goods is transferred to our customers, or services are performed, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Invoicing typically occurs upon shipment, or delivery in the case of an instrument, and payment is typically due within 30 days from invoice. In instances where the right to payment or transfer of title is contingent upon customer acceptance of the product, revenue is deferred until the acceptance criteria has been met. Revenue from instrument service contracts is recognized as the services are rendered, typically evenly over the contract term. Revenue from development agreements generally includes upfront and milestone payments. Revenue for these agreements is recognized when each separate performance obligation is satisfied.

We may enter into, or periodically modify, contracts with customers that include a combination of promised products and services, resulting in arrangements containing multiple performance obligations. We determine whether each product or service is distinct, in order to identify the performance obligations in the contract and allocate the contract transaction price among the separate performance obligations. A product or service is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. Therefore, instrument revenue is recognized upon transfer of control of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers and upon shipment for sales made to our distributor customers.

The consideration for contracts with multiple performance obligations is allocated between separate performance obligations based on their individual standalone selling price. We determine the best estimate of standalone selling price primarily using historical average selling prices combined with an assessment of current market conditions. If the standalone selling price is not directly observable, we rely on estimates by considering multiple factors including, but not limited to, overall market conditions, including geographic or regional specific factors, internal costs, profit objectives, pricing practices, and other observable inputs. We recognize revenues as performance obligations are satisfied by transferring control of the product or service to the customer or over the term of a product maintenance agreement with a customer. Our revenue arrangements generally do not provide a right of return. Revenue is recorded net of discounts and sales taxes collected on behalf of governmental authorities. We update the transaction price for expected consideration, subject to constraint. Where we expect, at contract inception, the timing of payments to be consistent with the transfer of goods or services or the contract duration to be one year or less, we do not adjust the transaction price for the effects of a significant financing component.

Modification of existing contracts with customers could change the scope or the price of the contract, or both. When a contract modification occurs, we exercise judgment to determine if the modification should be accounted for as: (i) a separate contract, (ii) the termination of the original contract and creation of a new contract, (iii) a cumulative catch-up adjustment to the original contract, or a combination thereof. Further, contract modifications require the identification and evaluation of the performance obligations of the modified contract, allocation of revenue to the remaining performance obligations and determination of the period of recognition for each identified performance obligation.

Certain of our agreements provide options to customers which can be exercised at a future date, such as the option to purchase our product at discounted prices, among others. In accounting for customer options, we determine whether an option is a material right and this may require us to exercise judgment. If a contract provides the customer an option to acquire additional goods or services at a discount that exceeds the range of discounts that we typically give for that product or service for the same class of customer, or if the option provides the customer certain additional goods or services for free, the option is considered a material right and, therefore, a performance obligation. If the standalone selling price of the option is not directly observable, an estimated standalone selling price is utilized which considers adjustments for discounts that the customer could receive without exercising the option and the likelihood that the option will be exercised.

Additionally, we generally provide a one-year warranty on instruments. We accrue the cost of the assurance warranty when revenue of the instrument is recognized. Employee sales commissions are generally recorded as selling, general, and administrative expense when incurred as the amortization period for such costs, if capitalized, would have been one year or less.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (“FIFO”) method. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess or obsolete balances. Cost includes depreciation, labor, material, and overhead costs, including product and process technology costs. Determining net realizable value of inventories involves judgements, including projecting future average selling prices, sales volumes, and costs to complete products in work in process inventories.

We make inventory purchases and commitments to meet future shipment schedules based on forecasted demand for our products. The business environment in which we operate is subject to rapid changes in technology and customer demand. We perform a detailed assessment of inventory each period, which includes a review of, among other factors, demand requirements, product life cycle and development plans, component cost trends, product pricing, product expiration, and quality issues. Based on our analysis, we record adjustments to inventory for potentially excess, obsolete, or impaired goods, when appropriate, to report inventory at net realizable value. Inventory adjustments may be required if actual demand, component costs, supplier arrangements, or product life cycles differ from our estimates. Any such adjustments would result in a charge to our results of operations.

Business Combinations

Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. Costs that we incur to complete the business combination, such as legal and other professional fees, are expensed as they are incurred.

In connection with certain acquisitions, contingent consideration can be earned by the sellers upon completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition date fair value of the contingent consideration. Changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in operating expenses on our consolidated statements of operations and comprehensive loss.

We typically use the discounted cash flow method to value our acquired intangible assets. This method requires significant management judgment to forecast future operating results and utilizes significant assumptions such as assumed revenue projections, discount rates and obsolescence factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expense could be accelerated or extended. We capitalize IPR&D, which is considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon reaching the end of the relevant research and development project (i.e., upon commercialization), the IPR&D asset is amortized over its estimated useful life. If the relevant research and development project is abandoned, the IPR&D asset is expensed in the period of abandonment.

If the initial accounting for a business combination is incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. We record these adjustments to the provisional amounts with a corresponding offset to goodwill. Any adjustments identified after the measurement period are recorded on our consolidated statements of operations and comprehensive loss.

We acquired $55.0 million of IPR&D, and $52.3 million of goodwill in connection with the acquisition of Apton Biosystems, Inc. in the third quarter of 2023.

Goodwill and Intangible Assets with Indefinite Lives — Impairment Assessment

Goodwill and other intangible assets with indefinite useful lives (i.e., IPR&D) are not amortized, however they are tested annually for impairment, as of the first day of the second and third quarter of our fiscal year, respectively, and whenever events or changes in circumstances indicate that it is more likely than not that the fair value is less than the carrying value. Events that could indicate impairment and trigger an interim impairment test include, but are not limited to, adverse changes in business or economic conditions, lower-than-expected performance of a product line or business, changes in strategic direction, unanticipated technological or competitive developments, loss of key personnel, and actions by governments or courts.

We perform our goodwill impairment analysis at the reporting unit level. We have one reporting unit, which aligns with our reporting structure and availability of discrete financial information. During the goodwill impairment review, we assess qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than the carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and our overall financial performance. If, after assessing the totality of these qualitative factors, we determine that it is not more likely than not that the fair value of our reporting unit is less than the carrying amount, then no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the reporting unit with the carrying value, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, we record an impairment loss based on the difference. We generally perform our impairment test using a combination of an income and a market approach to determine the fair value of goodwill. The income approach utilizes estimated discounted cash flows, while the market approach utilizes comparable company information. If a quantitative assessment is performed, the evaluation includes management estimates of cash flow projections based on internal future projections and/or use of a market approach by looking at market values of comparable companies, including the observable implied multiples of those companies. Key assumptions include, but are not limited to, revenue and operating income growth rates, discount rates and other factors. We consider peer revenues and earnings trading multiples from companies that have operational and financial characteristics that are similar to the asset under measurement and estimated weighted-average costs of capital. Different assumptions from those made in our analysis could materially affect projected cash flows and the evaluation of assets for impairment. We also consider our market capitalization as a part of our analysis. We may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative goodwill impairment test.

We recognized $144.5 million of impairment charges to goodwill during the year ended December 31, 2024, as a result of quantitative interim impairment tests.

Based primarily on the decline in our stock price and overall market capitalization during the first quarter of 2025, driven in part by macroeconomic uncertainties, as well as our updated strategic plans and restructuring initiatives that prioritize accelerating adoption of HiFi sequencing and ceasing development of our high-throughput short-read platform, we concluded that changes to the timing and amount of expected future cash flows, among other factors, indicated that it was more likely than not that the fair value of the reporting unit was less than its carrying amount, requiring an interim goodwill impairment assessment. As a result of the quantitative interim impairment test performed as of March 31, 2025, we concluded that there was no impairment, as the estimated fair value of the entity-level reporting unit exceeded the carrying value.

To determine the fair value of the entity-level reporting unit as of March 31, 2025, we performed our impairment test using a combination of an income approach and a market approach to determine the fair value of the reporting unit. The income approach utilized estimated discounted cash flows, while the market approach utilized comparable company information. Significant assumptions used in the income approach included revenue growth expectations and a selected discount rate of 12.0%. The discount rate was based on the weighted average cost of capital, determined using market, industry data, and related risk factors. The assumptions used were inherently subject to uncertainty. The assessment is a level 3 measurement due to its reliance on certain unobservable inputs and management judgment. The assessed fair value was deemed reasonable based on a market capitalization reconciliation and a supportable control premium.

We performed our annual assessment for goodwill impairment in the second quarter of 2025, noting no impairment. See Note 4. Balance Sheet Components in Part II, Item 8 of this Annual Report on Form 10-K for further information.

During the IPR&D impairment review, we assess qualitative factors to determine whether it is more likely than not that the fair value of the IPR&D is less than the carrying amount. The qualitative factors include, but are not limited to, macroeconomic conditions, industry-specific conditions, and company-specific conditions. If, after assessing the totality of these qualitative factors, we determine that it is not more likely than not that the fair value of the IPR&D is less than the carrying amount, then no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the IPR&D with the carrying value. If the carrying amount of the IPR&D exceeds the fair value, we record an impairment loss based on the difference. We generally perform our impairment test using an income approach to determine the fair value of IPR&D. The income approach utilizes estimated discounted cash flows. If a quantitative assessment is performed, the evaluation includes management estimates of cash flow projections based on internal future projections. Key assumptions include, but are not limited to, revenue projections, revenue growth rates, discount rates and other factors. Different assumptions from those made in our analysis could materially affect projected cash flows and the evaluation of assets for impairment. We may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative impairment test. There is substantial risk inherent in forecasting revenues and spend associated with research and development, including assumptions around the timing and level of resources and investment to be made.

We recognized a $40.0 million impairment charge during the year ended December 31, 2024 as a result of a quantitative interim impairment test.

During the first quarter of 2025, based on our decision to cease development of the high-throughput short-read sequencing platform, which would utilize the IPR&D, and the resulting changes to the expected future cash flows, among other factors, we concluded that it was more likely than not that the fair value of the IPR&D was less than its carrying amount, requiring an interim impairment assessment. Using a discounted cash flow model under the income approach, we determined the fair value was $0 and recorded a $15.0 million impairment charge. The decline in the fair value of the IPR&D to $0 as of March 31, 2025 resulted primarily from changes in the timing of expected future cash flows as compared to the fair value as of December 31, 2024, driven by the restructuring initiatives that prioritize accelerating adoption of HiFi sequencing and resulted in ceasing development of our high-throughput short-read sequencing platform. The impairment charge is included on our consolidated statements of operations and comprehensive loss for the year ended December 31, 2025. Significant estimates and assumptions used in the income approach include timing of future cash flows, revenue growth assumptions, a selected discount rate of 14.0%, and a selected obsolescence factor of 11 years. The discount rate was based primarily on the weighted average cost of capital, determined using market, peer company, industry data, and related risk factors. The assessment is a level 3 measurement due to its reliance on certain unobservable inputs and management judgment. The assumptions used were inherently subject to uncertainty. See Note 4. Balance Sheet Components in Part II, Item 8 of this Annual Report on Form 10-K for further information.

Assumptions and estimates about future values are complex and often subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of our reporting unit, we may be required to record future impairment charges for goodwill. Impairment charges could materially decrease our future results of operations and result in lower asset values on our balance sheet.

Intangible Assets and Other Finite-Lived Assets — Impairment Assessment

We capitalize finite-lived intangible assets and generally amortize such assets on a straight-line basis over their estimated useful lives. We review intangible assets with finite lives and other finite-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. We assess the recoverability of assets based on the estimated undiscounted future cash flows expected to result from the use and eventual disposition of the asset. If the undiscounted future cash flows are less than the carrying amount, we estimate the fair value of the assets and record an impairment loss if the carrying value exceeds the fair value. In light of the changes in circumstances that led to the recoverability assessment, we also assess the remaining estimated useful life of the assets. Factors that may indicate potential impairment include a significant decline in our stock price and market capitalization compared to net book value, significant changes in the ability of an asset to generate positive cash flows for our strategic business objectives, and the pattern of utilization of a particular asset.

Fiscal 2025 Form 10-K

Table of Contents

In order to estimate the fair values of identifiable intangible assets with finite lives and other finite-lived assets, we estimate the present value of future cash flows from those assets. The key assumptions that we use in our cash flow model are the amount and timing of estimated future cash flows to be generated by the asset over an extended period of time and a rate of return that considers the relative risk of achieving the cash flows, the time value of money, and other factors that a willing market participant would consider. Management judgment is required to estimate the amount and timing of future cash flows and the relative risk of achieving those cash flows.

Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of the asset group, we may be required to record future impairment charges. Impairment charges could materially decrease our future results of operations and result in lower asset values on our balance sheet.

Contingent Consideration

In connection with the acquisition of Omniome in the third quarter of 2021, we entered into an arrangement where we were obligated to pay $200 million in cash and equity dependent upon the achievement of a milestone event upon the first commercial shipment of products developed from our acquired sequencing technology. In the third quarter of 2023, we commenced customer shipments of the Onso short-read sequencing instrument. The milestone payment associated with PacBio’s acquisition of Omniome was triggered in September 2023 once both the Onso instrument and related consumables had been shipped to one customer. Consequently, we paid the former Omniome securityholders milestone consideration of an aggregate of approximately $100.9 million in cash and approximately 9.0 million shares of our common stock in October 2023.

In connection with the acquisition of Apton, we entered into an arrangement where we are obligated to pay former holders of Apton's outstanding equity interests $25.0 million upon the achievement of $50 million in revenue associated with a high throughput sequencer using Apton's technology, provided that the milestone event occurs prior to the five-year anniversary of the closing date of the acquisition, which we may elect to pay in cash, shares of our common stock or a combination of cash and shares of our common stock. See Note 2. Business Acquisitions in Part II, Item 8 of this Annual Report on Form 10-K for further information.

We estimate the fair value of the contingent consideration liability based on the simulated revenue of the Company through the five-year anniversary of the closing date of the acquisition. The key input used in the determination of the fair value included projected revenues of the high-throughput short-read products and services leveraging Apton's technology. Primarily due to management's decision to cease development of the high-throughput short-read system, and the resulting changes in the expected future revenues, among other factors, and as the milestone event must occur prior to the five-year anniversary of the closing date of the acquisition, the estimated fair value of the contingent consideration liability is $0. An increase in the fair value of the liability may result from changes in projected revenues, including accelerated timing or higher expected amounts, and from decreases in discount rates, including the risk-free rate and the estimated subordinated credit spread for a CCC credit rating. Refer to Note 3. Financial Instruments in Part II, Item 8 of this Annual Report on Form 10-K for further discussion on valuation assumptions.

On January 30, 2026, we completed a disposition of assets to Buyer in accordance with the terms of an Asset Purchase Agreement. In connection with the Asset Sale, Buyer will pay at our direction 4% of the net proceeds from the Purchase Price to the former equity holders of Apton related to the waiver of all remaining milestone obligations associated with our purchase of Apton in August 2023, which payment is expected in the first quarter of 2026. See Note 12. Subsequent Events in Part II, Item 8 of this Annual Report on Form 10-K for further details.
