**Notes to Unaudited Condensed Consolidated Financial Statements**

**1. Organization and Description of Business**

Twist Bioscience Corporation (the Company) was incorporated in the state of Delaware on February 4, 2013. The Company is a leading, rapidly growing synthetic biology company that has developed a disruptive DNA synthesis platform to industrialize the engineering of biology. The Company's fiscal year ends on September 30 .

The core of the Company's platform is a proprietary technology that pioneers a new method of manufacturing synthetic DNA by "writing" DNA on a silicon chip. The Company has combined our silicon-based DNA writing technology with proprietary software, scalable commercial infrastructure and an e-commerce platform to create an integrated technology platform that enables us to achieve high levels of quality, precision, automation, and manufacturing throughput at a significantly lower cost than our competitors. The Company has applied its unique technology to manufacture a broad range of synthetic DNA-based products, including synthetic genes, tools for next generation sequencing, or NGS, sample preparation, and antibody libraries for drug discovery and development, all designed to enable its customers to conduct research more efficiently and effectively. The Company has leveraged the same technology to expand its footprint beyond DNA synthesis to manufacture synthetic RNA as well as express antibody proteins and conduct many diverse assays to characterization these proteins to disrupt and innovate within larger market opportunities, in addition to discovery partnerships for biologic drugs. The Company has further expanded its offering to deliver data from the characterization of antibody proteins to our customers and partners.

The Company has recognized annual losses from operations since inception and has an accumulated deficit of $1,350.1 million as of December 31, 2025. For the three months ended December 31, 2025, the Company reported net loss of $30.5 million. The Company incurred net losses of $31.6 million for the same period in 2024.

As of December 31, 2025, the Company had cash and cash equivalents of $148.6 million and short-term investments of $49.4 million. The Company expects that its current cash, cash equivalents, and short-term investments will be sufficient to fund its operations for a period of at least one year from the date the condensed consolidated financial statements are issued.

**2. Summary of Significant Accounting Policies&nbsp;&nbsp;&nbsp;&nbsp;**

***Basis of Presentation***

The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2025 (the Annual Report on Form 10-K) filed with the Securities and Exchange Commission on November 17, 2025. The condensed consolidated financial statements are unaudited and have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet at September 30, 2025 is derived from audited consolidated financial statements but does not include all disclosures required by GAAP. The operating results for the three months ended December 31, 2025 are not necessarily indicative of the results expected for the full year ending September 30, 2026 or any interim period. Beginning fiscal 2026, the Company updated its revenue disaggregation disclosures and recast the comparative figures in the disclosure to conform to the current-period presentation (see Note 3, Revenue).

***Use of Estimates***

The presentation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

***Principles of Consolidation***

The Company's unaudited condensed consolidated financial statements include its wholly owned subsidiaries. All intercompany balances and accounts are eliminated in consolidation.

***Cash and Cash Equivalents and Restricted Cash***

The following table provides a reconciliation of the Company's cash and cash equivalents and non-current portion of restricted cash reported within the unaudited condensed consolidated balance sheets that sum to the total cash, cash equivalents and restricted cash shown in the Company's condensed consolidated statements of cash flows:

---

| | | |
|:---|:---|:---|
| **(in thousands)** | **December 31, 2025** | **September 30, 2025** |
| Cash and cash equivalents | $148591 | $183049 |
| Restricted cash, non-current | 2394 | 2376 |
| Total cash, cash equivalents and restricted cash | $150985 | $185425 |

---

***Significant Accounting Policies***

There have been no material changes in the accounting policies from those disclosed in the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K.

***Recent Accounting Pronouncements***

*New Accounting Pronouncements Not Yet Adopted* 

In December 2023, the FASB issued ASU No. 2023-09 "Income Taxes (Topic 740)". The amendments in this ASU require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. The amendments in this update are effective for annual periods beginning after December 15, 2024. The standard is not expected to have a material impact to the Company's consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, which will require additional expense disclosures for all public entities. The amendments require that at each interim and annual reporting period, an entity will disclose certain disaggregated expenses included in each relevant expense caption, as well as the total amount of selling expenses and, in annual periods, an entity's definition of selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the incremental disclosures that will be required in its consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software ("ASU 2025-06"), which became effective and simplifies the capitalization guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. The standard is effective for all entities for annual periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this standard to its consolidated financial statements.

The Company has evaluated other recently issued accounting pronouncements and has concluded that the impact of recently issued standards that are not yet effective will not have a material impact on the Company's financial position or results of operations upon adoption.

**3. Revenue**

The Company's revenue is generated through the sale of DNA synthesis and protein solutions and NGS applications.

---

(1) Consists of unbilled amounts primarily related to contracts where the Company has satisfied the performance obligations, but do not yet have the right to bill for.

(2) Consists of receipt of advance payments before the Company's performance obligations related to revenue contracts are met.

For the three months ended December 31, 2025 and December 31, 2024, the Company recognized revenue of $2.3 million and $1.7 million, respectively, from the amount that was included in the contract liability balance at the beginning of each period.

In addition, for all periods presented, there was no revenue recognized in a reporting period from performance obligations satisfied in previous periods. The aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied as of December 31, 2025 was $19.0 million. The Company expects to recognize revenue over the next twelve months relating to performance obligations unsatisfied as of December 31, 2025.

**5. Fair Value Measurement**

The Company assesses the fair value of financial instruments based on the provisions of ASC 820, *Fair Value Measurements*. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

*Level 1*—Quoted prices in active markets for identical assets or liabilities.

*Level 2*—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

*Level 3*—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considering counterparty credit risk in its assessment of fair value.

***Assets Measured at Fair Value on a Recurring Basis***

As of December 31, 2025, financial assets measured and recognized at fair value are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **(in thousands)** | **Level 1** | **Level 2** | **Level 3** | **Fair value** |
| **Assets** | | | | |
| Money market funds | $117597 | $— | $— | $117597 |
| U.S. government treasury bills | 49358 |  |  | 49358 |
| &nbsp;&nbsp;Total financial assets | $166955 | $— | $— | $166955 |

---

As of September 30, 2025, financial assets measured and recognized at fair value are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|

| U.S. government treasury bills | 49385 |  |  | 49385 |
| &nbsp;&nbsp;Total financial assets | $199757 | $— | $— | $199757 |

---

Contractual maturities of short-term investments, as of December 31, 2025, were less than 12 months. 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. Accrued interest receivable balances included in the prepaid expenses and other current assets within the condensed consolidated balance sheets were $0.8 million and $1.2 million as of December 31, 2025 and September 30, 2025, respectively.

As of December 31, 2025 and September 30, 2025, there were no financial liabilities measured and recognized at fair value.

There were no transfers between Level 1, Level 2 and Level 3 in the periods presented.

**6. Investment in Equity Securities**

The Company holds investments in privately-held companies in the form of equity securities without readily determinable fair values and in which the Company does not have a controlling interest or significant influence.

<u>[**Table of Contents**](#ic8b5f208d6c948d2a69d10088dd25388_1)</u>

The Company elected to account for its investment in these privately-held companies using the measurement alternative method. These investments had a net carrying value of $54.3 million and $54.3 million as of December 31, 2025 and September 30, 2025, respectively. There were no upward or downward adjustments for observable price changes or impairment charges recorded during the three months ended December 31, 2025 and 2024 related to these equity securities. The Company concluded that these entities are variable interest entities (VIEs) and the Company holds variable interests in these VIEs but is not their primary beneficiary. The Company does not have the power, whether through contractual relationships or other factors, to direct the activities that most significantly impact the economic performance of these VIEs. The Company's maximum exposure to loss from these VIEs consist of equity investments, promissory note receivable and other receivables of $56.4 million. See Note 11 for assets and liabilities of these VIEs.

**9. Leases**

The Company leases certain of its facilities under non-cancellable operating leases expiring at various dates through 2044. The Company is also responsible for utilities, maintenance, insurance, and property taxes under these leases. The lease payments consist primarily of fixed rental payments for the right to use the underlying leased assets over the lease terms, as well as payments for common-area-maintenance and administrative services. The Company often receives customary incentives from its landlords, such as reimbursements for tenant improvements and rent abatement periods, which effectively reduce the total lease payments owed for these leases. Leases are classified as operating or financing at commencement. The Company does not have any material financing leases.

On November 13, 2025, the Company entered into an amendment to a lease agreement for the Company's premises in South San Francisco, California, in order to consolidate other offices in South San Francisco into a single location. This amendment increases the leased premises by approximately 33,000 square feet ("Additional Premises") and extends the termination date of the lease until June 30, 2036. In accordance with the amended lease agreement, the monthly base rent for the entire premises is approximately $0.5 million at commencement and includes provisions for rent increases by 3% annually and provides for base rent abatement with respect to the original premises for 15 months and base rent abatement with respect to the Additional Premises for 12 months. The Company is also responsible for utilities, maintenance, insurance, and property taxes. The landlord will provide the Company with a tenant improvement allowance in connection with the Company's improvements to the premises of approximately $24.4 million. The amendment also gives the Company the right, on or before December 31, 2026, to elect to expand the premises to include additional space in the building of approximately 33,000 square feet.

Certain leases include options to renew or terminate at the Company's discretion. The lease terms include periods covered by these options if it is reasonably certain the Company will renew or not terminate. The Company's lease agreements do not contain any material residual value guarantees or restrictive covenants.

As part of the sale of DNA data storage business, the Company subleased specific office and lab space in South San Francisco.

Future minimum lease payments and sublease income under all non-cancelable operating leases as of December 31, 2025 are as follows:

**10. Commitments and Contingencies**

***Legal Proceedings***

The Company may be subject to litigation, claims and disputes in the ordinary course of business. Certain significant matters are described below. The Company recognizes accruals for matters to the extent that the Company concludes that a loss is both probable and reasonably estimable. If the Company determines that a material loss is reasonably possible and the loss or range of loss can be estimated, the Company discloses the possible loss.

*Securities Class Action*

On December 12, 2022, a putative securities class action lawsuit captioned Peters v. Twist Bioscience Corporation, et al., Case No. 22-cv-08168 (N.D. Cal.) ("Securities Class Action") was filed in federal court in the Northern District of California ("Court") against the Company, its Chief Executive Officer, and its Chief Financial Officer (the "Defendants") alleging violations of federal securities laws. The Securities Class Action's claims are based in large part on allegations made in a report issued on November 15, 2022 by Scorpion Capital ("Scorpion Report") concerning, among other things, the Company's DNA chip technology and accounting practices. The initial complaint filed in the Securities Class Action alleges that various statements that the

------

<u>[**Table of Contents**](#ic8b5f208d6c948d2a69d10088dd25388_1)</u>

Defendants made between December 13, 2019 and November 14, 2022 were materially false and misleading in light of the allegations in the Scorpion Report. The plaintiff who initiated the lawsuit sought to represent a class of shareholders who acquired shares of the Company's common stock between December 13, 2019 and November 14, 2022 and sought damages as well as certain other costs. On July 28, 2023, the Court appointed a new plaintiff, not the original plaintiff who filed the case, as lead plaintiff in the case and appointed a new law firm as lead counsel. On October 11, 2023, the lead plaintiff filed an amended complaint. The amended complaint is purportedly brought on behalf of all persons other than the Defendants who acquired the Company's securities between December 20, 2018 and November 15, 2022. The amended complaint alleges that certain statements regarding, among other things, the Company's DNA products and accounting practices were false and misleading. On December 6, 2023, the Company filed a motion to dismiss the amended complaint and a hearing on the motion to dismiss was held on November 13, 2024. On September 3, 2025, the Court issued an order granting in part and denying in part Defendants' motion to dismiss and granted the plaintiff leave to further amend by September 24, 2025. The plaintiff did not file a second amended complaint. The Company is engaged in discovery and intends to continue vigorously defending the remaining claims under this action in all respects.

Given the inherent uncertainty of litigation and the legal standards that must be met, including class certification and success on the merits, the Company cannot express an opinion on the likelihood of an unfavorable outcome or on the amount or range of any potential loss.

*Derivative Action*

On September 25, 2023, a shareholder derivative suit captioned Shumacher vs. Leproust et al., No. 1:23-cv-01048-UNA, was filed in the United States District Court for the District of Delaware against directors of the Company and an employee (the "Shumacher Action"). The suit is based on substantially the same allegations in the Securities Class Action and seeks to recover, on behalf of the Company, damages to the Company arising from, among other things, the Securities Class Action. On November 13, 2023, the parties to the Shumacher Action entered into a stipulation staying the Shumacher Action pending further proceedings in the Securities Class Action. On November 13, 2025, another derivative lawsuit captioned Sell v. Leproust, et al., Case No. 1:25-cv-01380-MN was filed in the Delaware Court of Chancery, averring similar claims and seeking similar recovery as the Shumacher Action (the "Sell Action"), and on December 2, 2025 the Sell Action was consolidated with the Shumacher Action and stayed pending further proceedings in the Securities Class Action.

**15. Segment Information** 

The Company operates in one operating segment, which also represents one reportable segment with the Company's Chief Executive Officer as the chief operating decision maker (CODM). The CODM reviews the Company's operating results on a consolidated basis for purposes of allocating resources and evaluating financial performance. Specifically, the CODM evaluates the Company's financial performance and decides how to allocate resources based on consolidated net income (loss), which enables the CODM to assess both the overall level of resources available and optimize distribution of resources across functions, product lines, regions and research and development programs in line with our long-term corporate-wide strategic goals. The CODM also reviews disaggregated revenue by product line, geographic regions, and industry (see Note 3).

**Overview**

We offer customizable solutions across the biological continuum. We have developed a disruptive DNA synthesis platform to industrialize the engineering of biology. The core of our platform is a proprietary technology that pioneers a new method of manufacturing synthetic DNA by "writing" DNA on a silicon chip. We have combined our silicon-based DNA writing technology with proprietary software, scalable commercial infrastructure and an e-commerce platform to create an integrated technology platform that enables us to achieve high levels of quality, precision, automation, and manufacturing throughput at a significantly lower cost than our competitors. We have applied our unique technology to manufacture a broad range of synthetic DNA-based products, including synthetic genes, tools for next generation sequencing, or NGS, sample preparation, and antibody libraries for drug discovery and development, all designed to enable our customers to conduct research more efficiently and effectively. Leveraging our same technology, we have expanded our footprint beyond DNA synthesis to manufacture synthetic RNA as well as express antibody proteins and conduct many diverse assays to characterize these proteins. We have further expanded our offering to deliver data from the characterization of antibody proteins to our customers and partners.

We believe our products enable a broad range of applications that may ultimately improve health and the sustainability of the planet across multiple industries including therapeutics, diagnostics, industry and applied, academic research and government, and global supply partners revenue. We sell our synthetic DNA and synthetic DNA-based products to a customer base of more than 3,800 customers annually across a broad range of industries. In order to address this diverse customer base, we employ a multi-channel strategy comprised of a direct sales force targeting synthetic DNA customers, a direct sales force focusing on the NGS market and an e-commerce platform that serves both commercial channels. We employ business development and sales representatives for our protein solutions and biologics discovery service offering. Our easy-to-use e-commerce platform allows customers to design, validate and place on-demand orders of customized DNA online, and enables them to receive real-time customized quotes for their products and track their order status through the manufacturing and delivery process. This is a critical part of our strategy to address our large markets and diverse customer base, as well as drive commercial productivity, enhance the customer experience, and promote loyalty.

We generate revenue through our DNA synthesis and protein solutions as well as our NGS applications. As we have moved further up the value chain from fragments to genes to preps to proteins and beyond, the strategic connection between what we previously described as our "synthetic biology" portfolio and "biopharma services" tightens. Beginning fiscal 2026, we combined revenue from synthetic biology tools and biopharma services into a new category called DNA synthesis and protein solutions. Additionally, we renamed NGS tools to NGS applications to better reflect their role in DNA sequencing workflows.

Since our inception, we have incurred net losses each year. Our net loss for the three months ended December 31, 2025 was $30.5 million compared to a net loss of $31.6 million for the three months ended December 31, 2024. As of December 31, 2025, we have accumulated net deficit of $1,350.1 million and cash, cash equivalents and short-term investments of $197.9 million. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the success of our existing products and the development and commercialization of additional products in the synthetic biology and biologic drug industries as well as leveraging our investment in our manufacturing facility in Wilsonville, Oregon.

Financial highlights from three months ended December 31, 2025, compared to the three months ended December 31, 2024, include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenues growth of 16.9% to $103.7 million from $88.7 million, primarily due to growth in NGS Applications and DNA Synthesis and Protein Solutions revenues;

------

<u>[**Table of Contents**](#ic8b5f208d6c948d2a69d10088dd25388_1)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin increased to 52.0% from 48.3% primarily due to increases in revenues and driving additional cost savings through continuous process improvement initiatives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss from operations decreased to $32.9 million from $34.6 million primarily due to an increase in both revenues and gross profit. Additionally, contributing factors were a decrease in research and development expenses, offset by an increase in selling, general and administrative expenses for the three months ended December 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net cash used in operating activities increased to $24.8 million from $21.4 million.

***Revenues by Products***

We historically reported our revenue by the following products: synthetic genes, oligo pools and DNA libraries (collectively, synthetic biology), antibody discovery, and NGS tools. Beginning fiscal 2026, we combined revenue from synthetic genes, oligo pools, DNA libraries, and biopharma services for antibody discovery into DNA synthesis and protein solutions. We also changed the name of NGS tools to NGS applications, as these products and services facilitate DNA reading and sequencing workflows. The table below summarizes revenues by the new products:

***Revenues by Industry***

------

<u>[**Table of Contents**](#ic8b5f208d6c948d2a69d10088dd25388_1)</u>

We historically reported revenue by industrial chemicals/materials, academic research, healthcare, and food/agriculture. Beginning fiscal 2026, we will disclose revenue by therapeutics, diagnostics, industry and applied, academic research and government, and global supply partners revenue. These updated categories better align with our operations and increase clarity around our key customer groups. The table below summarizes revenues by industry:

---

| | | | | |
|:---|:---|:---|:---|:---|

***Product Shipments Including Synthetic Genes***

The table below summarized product shipments including synthetic genes:

---

| | | |
|:---|:---|:---|
| | **Three months ended December 31,** | **Three months ended December 31,** |
| **(in thousands)** | **2025** | **2024** |
| Number of genes shipped | 271 | 205 |

---

The number of customers who purchased products from us were approximately 2,538 and 2,376 customers for the three months ended December 31, 2025 and 2024, respectively.

Revenues increased 16.9% to $103.7 million for the three months ended December 31, 2025, as compared to $88.7 million for the three months ended December 31, 2024. The increase in revenues primarily reflects growth in NGS Applications revenue of 8.2% and growth in DNA Synthesis and Protein Solutions revenue of 27.4%, both of which are primarily attributable to increase in revenues from our customers in therapeutics, global supply partners, and industry and applied industries, primarily driven by an increase in number of customers. The number of genes shipped in the three months ended December 31, 2025, increased to approximately 271,000 genes, compared to approximately 205,000 genes in the three months ended December 31, 2024, an increase of 32.2%.

**Cost of Revenues**

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three months ended December 31,** | **Three months ended December 31,** | **Three months ended December 31,** | **Three months ended December 31,** |
| **(in thousands, except percentages)** | **2025** | **2024** | **Change** | **%** |

| Gross profit | $53972 | $42840 | $11132 | 26% |
| Gross margin | 52.0% | 48.3% | 3.7% |  |

---

Cost of revenues increased 8% to $49.7 million for the three months ended December 31, 2025, as compared to $45.9 million for the three months ended December 31, 2024. The increase is primarily attributable to an increase in material costs of $2.7 million driven by increased sales and a $1.4 million increase in personnel costs. Gross margin increased 3.7% to 52.0% for the three months ended December 31, 2025, as compared to 48.3% in the same period of the prior year, mainly due to increase in revenues and driving additional cost savings through continuous process improvement initiatives.

**Research and Development Expenses**

| Research and development | $17130 | $21307 | $(4177) | (20)% |

---

Research and development expenses decreased 20% to $17.1 million for the three months ended December 31, 2025, as compared to $21.3 million for the three months ended December 31, 2024. The decrease is primarily driven by a $2.6 million decrease in personnel costs, including a $1.1 million decrease in stock-based compensation expenses, a $0.9 million decrease in outside services costs, and a $0.6 million decrease in costs for facilities and depreciation and amortization. These decreases are largely attributable to the sale of our DNA digital data storage business in fiscal year 2025.

**Selling, General and Administrative Expenses**

| Selling, general and administrative | $69742 | $56177 | $13565 | 24% |

---

Selling, general and administrative expenses increased 24% to $69.7 million for the three months ended December 31, 2025, as compared to $56.2 million for the three months ended December 31, 2024. The increase is primarily attributable to a $7.7 million increase in personnel costs, including a $2.4 million increase in stock-based compensation expense, and a $5.4 million increase in outside services costs as we continue to scale our commercial organization and invest into our corporate infrastructure.

**Interest and Other Income (Expense), net**

| Total interest and other income (expense), net | $2646 | $3147 | $(501) | (16)% |

---

Interest income decreased 33% to $2.2 million for the three months ended December 31, 2025, as compared to $3.2 million for the three months ended December 31, 2024, due to lower cash equivalents and short-term investments balances and lower interest rates.

We recorded an income tax provision of $0.3 million and $0.1 million for the three months ended December 31, 2025 and December 31, 2024, respectively.

**Liquidity and Capital Resources**

**Sources of Liquidity**

To date, we have financed our operations principally through public equity raises, private placements of our convertible preferred stock, borrowings from credit facilities, proceeds from the royalty purchase agreement, sale of DNA digital data storage assets and revenue from our commercial operations. At December 31, 2025, we had a balance of $148.6 million of cash and cash equivalents and $49.4 million in short-term investments.

------

<u>[**Table of Contents**](#ic8b5f208d6c948d2a69d10088dd25388_1)</u>

**Operating Capital Requirements**

Our primary uses of capital are, and we expect will continue to be for the near future, compensation and related expenses, manufacturing costs, laboratory and related supplies, legal and other regulatory expenses and general overhead costs, including facilities costs and capital expenditures. We had $12.9 million in commitments for capital expenditures as of December 31, 2025.

**Cash Flows**

The following table summarizes our sources and uses of cash and cash equivalents:

| Net cash provided by (used in) investing activities | (9933) | (1536) |
| Net cash provided by financing activities | 298 | 17944 |

---

***Operating Activities***

Net cash used in operating activities was $24.8 million during the three months ended December 31, 2025, which was primarily due to a net loss of $30.5 million, adjusted for non-cash items, including depreciation and amortization of $6.2 million, stock-based compensation expense of $13.3 million, and a net cash outflow from operating assets and liabilities of $13.4 million. The net cash outflow from operating assets and liabilities was mainly due to increases in inventories of $4.6 million and prepaid and other current assets of $7.7 million, and a decrease in accrued compensation of $12.4 million, partially offset by increase in accounts receivable of $6.8 million, due to the increase in revenues and the timing of collections, and decreases in accounts payable of $1.5 million, other liabilities of $1.3 million and accrued expenses of $1.5 million. The changes in accrued compensation, accrued expenses, and accounts payable are due to timing of payments to vendors and employees.

Net cash used in operating activities was $21.4 million during the three months ended December 31, 2024, which was primarily due to a net loss of $31.6 million, adjusted for non-cash items, including depreciation and amortization of $6.4 million, stock-based compensation expense of $12.0 million, and a net cash outflow from operating assets and liabilities of $8.2 million. The net cash outflow from operating assets and liabilities was mainly due to an increase in accounts receivable of $4.5 million due to timing of collections, a decrease in accrued compensation of $11.9 million offset by increases in accrued expenses of $3.1 million and accounts payable of $5.7 million. The changes in accrued compensation, accrued expenses, and accounts payable are due to timing of payments to vendors and employees.

***Investing Activities***

Net cash used in investing activities was $9.9 million during the three months ended December 31, 2025, which consisted of the purchases of property and equipment of $10.0 million.

Net cash used in investing activities was $1.5 million during the three months ended December 31, 2024, which consisted of the purchases of laboratory property, equipment and computers of $2.3 million offset by the proceeds from the net impact of purchases and maturity of investments of $0.7 million.

***Financing Activities***

Net cash provided by financing activities was $0.3 million in the three months ended December 31, 2025, which consisted of $0.3 million from the exercise of stock options.

Net cash provided by financing activities was $17.9 million in the three months ended December 31, 2024, which consisted of $15.0 million from sale of future revenue and $3.0 million from the exercise of stock options.

**Off-balance Sheet Arrangements**

We do not have any off-balance sheet arrangements.

**Contractual Obligations and Other Commitments**

Our contractual obligations have not materially changed from those reported in our Annual Report on Form 10-K except for lease commitments. As of December 31, 2025, our operating lease liability was $98.1 million. See note 9, Leases of the notes to our condensed consolidated financial statements included elsewhere in this Form 10-Q for information on our operating lease commitments.

**Critical Accounting Policies and Significant Management Estimates**

The preparation of our Condensed Consolidated Financial Statements in accordance with generally accepted accounting principles in the United States of America requires management to make estimates and judgments that affect the reported amounts in the financial statements and related disclosures. On an ongoing basis, we evaluate our significant accounting policies and estimates. We base our estimates on historical experience and on various market-specific and other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Estimates are assessed each period and updated to reflect current information. Actual results may differ significantly from these estimates. A summary of our critical accounting policies and estimates is presented in Part II, Item 7 of our Annual Report on Form 10-K. There were no changes to our critical accounting policies and estimates during the three months ended December 31, 2025.

**Recent Issued Accounting Pronouncements**

For a description of accounting changes and recent accounting pronouncements, including the expected dates of adoption and estimated effects, if any, on our condensed consolidated financial statements, see Note 2, "Summary of Significant Accounting Policies" in Item 1 of Part I of this Form 10-Q.

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

Information about our market risk is presented in Part II, Item 7A "Quantitative and Qualitative Disclosures about Market Risk" of our Annual Report on Form 10-K. Our exposure to market risk has not changed materially since September 30, 2025.

**Item 4. *Controls and Procedures***

**Evaluation of Disclosure Controls and Procedures**

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2025, which is the end of the period covered by this Form 10-Q. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures to ensure that information required to be disclosed by the Company in reports we file or submit under the Exchange Act is (i) recorded, processed, summarized, evaluated and reported, as applicable, within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures were effective as of December 31, 2025.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Limitations on Effectiveness of Controls and Procedures**

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, as specified above. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met.

In addition, we are subject to various legal proceedings and claims arising in the ordinary course of business. Although occasional adverse decisions or settlements may occur, management believes that the final disposition of such matters will not have a material adverse effect on our business, financial position, results of operations or cash flows.

**Item 1A. *Risk Factors***
