This discussion contains forward-looking statements based upon current plans, expectations and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including, but not limited to, those discussed in the section entitled “Risk Factors” and elsewhere in this Form 10-Q. In preparing this MD&A, we presume that readers have access to and have read the MD&A in our Annual Report on Form 10-K, pursuant to Instruction 2 to paragraph (b) of Item 303 of Regulation S-K.

Overview

We provide customizable solutions across the biological continuum that enable scientific discovery and development across therapeutics, diagnostics, and other high-growth markets. Our proprietary silicon-based platform delivers precision, scale, and speed, supporting consistent, high-quality performance across a broad range of applications.

At the core of our platform is a differentiated method of manufacturing synthetic DNA by “writing” DNA on a silicon chip. By integrating proprietary hardware, software, and scalable infrastructure, including our e-commerce platform, we achieve high levels of precision, automation, and throughput at a lower cost relative to legacy methods.

We have extended this platform beyond DNA synthesis to offer an integrated portfolio that includes synthetic genes, next-generation sequencing, or NGS, applications, sample preparation tools, antibody libraries, and biologics discovery services. These solutions are designed to improve research efficiency, accelerate development timelines, and deliver reproducible, high-quality data. Leveraging the same platform, we also manufacture synthetic RNA, express antibody proteins, perform characterization assays and deliver data to customers and partners.

Our solutions support a wide range of applications, including traditional and AI-enabled therapeutics discovery, diagnostic development, industrial and applied research, agricultural biotechnology, and academic research. By increasing efficiency and scalability in research and development, we support efforts to improve human health and sustainability.

We serve more than 3,800 customers annually across therapeutics, diagnostics, industrial and applied markets, academia, government, and global supply partners. Our multi-channel commercial strategy includes direct sales teams aligned to key markets and an e-commerce platform that enables customers to design, validate, and order customized products on demand, with real-time pricing and order tracking.

We generate revenue primarily from DNA synthesis and protein solutions and NGS applications. As we have expanded from DNA fragments to genes, sample preparation, protein expression, and biologics discovery, the integration of our offerings has strengthened. Beginning in fiscal 2026, we combined synthetic biology tools and biopharma services into a single category, DNA synthesis and protein solutions, and renamed NGS tools to NGS applications to reflect their role in sequencing workflows.

In February 2026, we entered into a license agreement with Invenra Inc. for its proprietary B-Body bispecific antibody discovery platform and simultaneously acquired a 6.24% ownership interest on a fully-diluted basis in Invenra through the purchase of Series B Preferred Stock. Together, these transactions represent a total commitment of $33.8 million, settled through a combination of cash and common stock.

Since our inception, we have incurred net losses each year. Our net loss for the three and six months ended March 31, 2026 was $44.0 million and $74.5 million, respectively. As of March 31, 2026, we have an accumulated net deficit of $1,394.1 million and cash, cash equivalents and short-term investments of $171.7 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 therapeutics, diagnostics, industry and applied, academic research and government, and global supply partners revenue industries as well as leveraging our investment in our manufacturing infrastructure.

Overview

We are a leading, rapidly growing synthetic biology company that has 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 ("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 antibody proteins to disrupt and innovate within larger market opportunities, in addition to discovery partnerships for biologic drugs.

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 healthcare, chemicals/materials, food/agriculture, academic research, and technology. 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 biopharma solutions as well. 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.

As we have moved further up the value chain from fragments to genes to preps to proteins and beyond, the strategic connection between our SynBio and Biopharma products tightens. More customers now leverage both products and services to accelerate discovery and identify breakthrough therapeutics. This growing convergence highlights the power of our integrated platform and reinforces Twist’s unique position to serve the full spectrum of innovation in discovery.

We currently generate revenue through our synthetic biology and NGS tools product lines as well as biopharma services for antibody discovery, optimization and development.

We generated revenues of $376.6 million, $313.0 million, and $245.1 million in the years ended September 30, 2025, September 30, 2024, and September 30, 2023, respectively, while incurring net losses of $77.7 million, $208.7 million and $204.6 million in the years ended September 30, 2025, 2024 and 2023, respectively. Since our inception, we have incurred significant operating losses and have accumulated a net deficit of $1,319.6 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.

We sold our DNA data storage business to Atlas Data Storage, Inc. ("Atlas"), a newly formed company, that will focus solely on DNA data storage technology and commercialization, with $155.0 million in seed financing round from third-party investors. The purpose of the transaction was to unlock value by accelerating data storage technology development and allowing each company to focus strategically on its unique products, customers and investors. Under the terms of the contribution agreement executed with Atlas, we assigned and licensed our DNA data storage technology to Atlas in exchange of receiving a minority ownership interest upon close, an upfront cash payment and a secured promissory note. We retained an ownership stake in Atlas and may participate in the upside of DNA data storage through future technology and commercial milestone payments, and a revenue share through royalties on future sales of Atlas’ products and services.

Financial highlights from fiscal year 2025 compared with fiscal year 2024 include:

•Revenue growth of 20% to $376.6 million from $313.0 million, primarily due to growth in NGS tools and synthetic genes;

•Gross margin increased to 50.7% from 42.6%, mainly due to increase in revenues and holding fixed manufacturing costs relatively flat and driving additional cost savings through continuous process improvement initiatives;

•Loss from operations decreased to $(136.3) million from $(220.8) million primarily due to an increase in both revenues and gross profit for the year ended September 30, 2025, and impairment of long-lived assets recognized in the year ended September 30, 2024. Additional contributing factors were a decrease in research and development expenses offset by an increase in selling, general and administrative expenses for the year ended September 30, 2025;

•Net cash used in operating activities for the year ended September 30, 2025 decreased to $47.6 million from $64.1 million for the year ended September 30, 2024; and

•Gain on the sale of DNA digital data storage business of $48.8 million.

Key Business Metrics

We regularly review the following key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions. We believe that the following metrics are representative of our current business. However, we anticipate these will change or may be substituted for additional or different metrics as our business grows.

Number of Genes Shipped

We believe that the number of genes shipped serves as a direct indicator of our operational efficiency and market demand. This metric is crucial for assessing our performance in meeting customer demand and generating revenues. Shipments of number of genes in years ended September 30, 2025 and 2024 were as follows:

Revenues increased 20% to $376.6 million for the year ended September 30, 2025, as compared to $313.0 million for the year ended September 30, 2024. The increase in revenue primarily reflects growth in NGS tools revenue of $39.0 million, growth in synthetic genes revenue of $20.9 million and growth in antibody discovery revenue of $3.1 million. These improvements in revenues from NGS tools and synthetic gene are largely due to higher sales to our customers in the healthcare, industrial chemicals/materials and academic research industries, as well as an increase in the number of customers. The number of our genes shipped for the year ended September 30, 2025 increased to approximately 938,000 genes, compared to approximately 772,000 genes for the year ended September 30, 2024, an increase of 22%.

Cost of Revenues

Cost of revenues reflects the aggregate cost incurred in the production and delivery of our products and consists of production materials, personnel costs, cost of expensed equipment and consumables, laboratory supplies, consulting costs, depreciation, production overhead costs, information technology (“IT”), maintenance and facility costs. Personnel costs consist of salaries, employee benefit costs, bonuses, and stock-based compensation expense. In addition, cost of revenue includes royalty costs for licensed technologies included in the Company’s products and provisions for slow-moving and obsolete inventory. We expect that our cost of revenues will vary with changes in our revenues and our revenue mix.

Cost of revenues increased 3% to $185.6 million for the year ended September 30, 2025, as compared to $179.6 million for the year ended September 30, 2024. The increase is primarily attributable to an increase in material costs of $9.4 million, due to higher sales volume and an increase in stock-based compensation expense of $3.0 million. These cost increases were partially offset by decreases in depreciation and amortization of $4.6 million and a decrease in outside service costs of $2.2 million. Gross margin increased 8.1% to 50.7% for the year ended September 30, 2025, as compared to 42.6% for the year ended September 30, 2024, mainly due to an increase in revenue, holding fixed manufacturing costs relatively flat, and driving additional cost savings through continuous process improvement initiatives.

Research and development expenses decreased 12% to $80.3 million for the year ended September 30, 2025, as compared to $90.9 million for the year ended September 30, 2024. This reduction is primarily attributed to lower personnel costs of $4.9 million and a decrease in stock-based compensation expense of $2.2 million, both driven by the sale of DNA digital data storage business. The remaining decrease is attributable to a reduction in outside services costs of $1.1 million and a reduction of depreciation and amortization of $1.8 million. The decrease in depreciation and amortization is mainly due to impairment of Biopharma assets in 2024 and the sale of DNA digital data storage business in the current year.

Selling, General and Administrative Expenses

Selling expenses consist of personnel costs, customer service expenses, direct marketing expenses, educational and promotional expense, market research and analysis. General and administrative expenses are incurred for executive, finance and accounting, legal and human resources functions and consist of personnel costs, audit and legal expenses, consulting costs, depreciation, insurance costs, travel expenses, rent, IT, maintenance and facility costs. Personnel costs consist of salaries, employee benefit costs, bonuses, commissions and stock-based compensation expense. We expense all selling, general and administrative expenses as incurred. We expect our selling costs will continue to increase in absolute dollars, primarily driven by our efforts to expand our commercial capability, with an increased presence both within and outside the United States, and to expand our brand awareness and customer base through targeted marketing initiatives.

Liquidity and Capital Resources

To date, we have financed our operations principally through public equity raises, private placements of our convertible preferred stock, borrowings from credit facilities and revenue from our commercial operations. As of September 30, 2025, we had a balance of $183.0 million of cash and cash equivalents and $49.4 million in short-term investments.

On October 21, 2024, the Company executed the Royalty Purchase Agreement with XOMA (US) LLC ("XOMA Royalty"). Under the Royalty Purchase Agreement, XOMA Royalty provided Twist Bioscience an upfront payment of $15.0 million in cash in exchange for the right to receive half of the future potential milestone and royalty payments resulting from certain antibody discovery and biopharma services agreements between the Company and its customers (see note 17 of the consolidated financial statements included elsewhere in this Form 10-K).

On May 2, 2025, the Company executed the Contribution Agreement with Atlas for the sale and transfer of its DNA digital data storage assets including the related intellectual property, equipment and contracts and the license of certain other intellectual property and the license of certain other intellectual property for a consideration of 73.0 million shares of Series Seed-1 Preferred Shares of Atlas, upfront cash consideration of $2.5 million, promissory notes of $2.0 million issued by Atlas, contingent manufacturing and commercial milestone payments of up to $75.0 million, and royalty payments based on a percentage of Atlas sales of the DNA data storage products (see note 6 of the consolidated financial statements included elsewhere in this Form 10-K).

Our primary cash needs are for operating expenses, working capital and capital expenditures to support the growth in our business. We believe that our existing cash, cash equivalents, restricted cash and short-term investments and anticipated cash flows from operations, will be sufficient to meet our anticipated cash requirements for more than 12 months from the date of this Form 10-K. In the future, we may still need to obtain additional financing to fund operations beyond this period, and there can be no assurance that we will be successful in raising additional financing on terms which are acceptable to us. In addition, our operating plans may change as a result of factors currently unknown to us, and we may need to seek additional funds sooner than planned. Such financing may result in dilution to stockholders, imposition of debt covenants and repayment obligations, or other restrictions that may adversely affect our business. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Our future capital requirements will depend on many factors. See “Risk Factors—We may require additional financing to achieve our goals, and such additional financing may not be available acceptable terms, or at all, which could have an adverse effect on our business".

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 and the capital expenditures. We had $17.5 million in commitments for capital expenditures as of September 30, 2025.

In fiscal year 2025, our net cash used in the investing activities was $24.8 million primarily as a result of purchases of property and equipment of $28.0 million, offset by the proceeds from the sale of our data storage business of $2.5 million, and the net result of purchases and maturity of investments of $0.7 million.

In fiscal year 2024, our net cash used in the investing activities was $3.1 million primarily as a result of the net result of purchases and maturity of investments of $2.0 million and purchases of property and equipment of $5.1 million.

Financing Activities

Net cash provided by financing activities was $28.5 million in fiscal year 2025, which consisted of $15.0 million from XOMA for the sale of future revenue, $9.3 million from the exercise of stock options, and $4.2 million from proceeds from issuance of shares under our employee stock purchase plan.

Net cash provided by financing activities was $6.9 million in fiscal year 2024, which consisted of $7.1 million from the exercise of stock options and $3.8 million from proceeds from issuance of shares under our employee stock purchase plan, offset by $4.0 million in repurchases of common stock for income tax withholdings.

Off-balance Sheet Arrangements

We do not have any off-balance sheet arrangements other than our indemnification agreements as described in Note 10 of the consolidated financial statements included elsewhere in this Form 10-K.

Contractual Obligations and Other Commitments

As of September 30, 2025, our operating lease obligation was $75.6 million related to various operating lease arrangements for facilities. See Note 9, Leases, of the notes to the consolidated financial statements included elsewhere in this Form 10-K for further discussion relating to these lease obligations.

On November 13, 2025, we entered into a lease amendment for our facilities in South San Francisco, California. This amendment increases the leased premises by approximately 33,000 square feet in order to consolidate other offices in South San Francisco into a single location and extends the termination date of the lease until June 30, 2036. The amendment also gives us the right, on or before December 31, 2026, to elect to expand the premises to include the entire fourth floor of the building containing approximately 33,000 square feet. For more information, please see Part II, Item 9B and Note 19, Subsequent Events of the notes to our consolidated financial statements included elsewhere in this Form 10-K.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, management evaluates the reasonableness of its estimates. Management bases its estimates on historical experience and on various assumptions that are believed 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 available from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

We believe the following critical accounting policies require that we make significant judgments and estimates in preparing our consolidated financial statements.

Revenue Recognition

Our revenue is generated through the sale of synthetic biology tools, such as synthetic genes, or clonal genes and fragments, oligonucleotide pools, or oligo pools, NGS tools, DNA libraries, and biopharma services for antibody discovery, optimization and development ("Biopharma").

We recognize revenue for synthetic biology tools, NGS tools, and DNA libraries when control of the products is transferred to the customer and at a transaction price that is determined based on the agreed upon rates in the applicable order or master supply agreement. Our sales are primarily subject to Ex Works delivery terms and is recorded at the point in time when products are picked up by the customer’s freight forwarder, as we have determined that this is the point in time that product control transfers to the customer. Shipping and handling are considered fulfillment costs and included in revenue. Taxes are excluded, and no significant financing components exist due to short payment terms.

Our Biopharma revenue consists of research and development agreements that may include up-front payments, milestone payments, or payments based on the timing of the development activities. Our research and development agreements may include more than one performance obligation. At the inception of the agreement, we assess whether each obligation represents a separate performance obligation or whether such obligations should be combined as a single performance obligation. The transaction price for each agreement is determined based on the amount of consideration we expect to be entitled to for satisfying all performance obligations within the agreement. We assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. In agreements where we satisfy performance obligation(s) over time, we recognize development revenue typically using an input method based on our costs incurred relative to the total expected cost which determines the extent of our progress toward completion. As part of the accounting for these arrangements, we must develop estimates and assumptions that require judgment to determine the transaction price and progress towards completion. We review our estimate of the transaction price and progress toward completion based on the best information available to recognize the cumulative progress toward completion as of the end of each reporting period and make revisions to such estimates as necessary.

Stock-based Compensation

We have granted stock-based awards, consisting of restricted stock and stock options, to our employees, certain non-employee consultants and certain members of our board of directors. We measure stock-based compensation expense for restricted stock and stock options granted to our employees and directors on the date of grant and recognize the corresponding compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. We measure stock-based compensation expense for restricted stock and stock options granted to non-employee consultants on the date of grant and recognize the corresponding compensation expense of those awards over the period in which the related services are received. We adjust for actual forfeitures as they occur.

We grant performance-based restricted stock units (PRSUs) to employees. We value PRSUs using a grant date fair value equal to the closing share price of our common stock on the date of grant and the probability of the achievement of the performance conditions.

We did not grant any options during the years ended September 30, 2025 and 2024.

55

Table of Contents

Goodwill

We test goodwill for impairment in our fourth quarter each year, or more frequently if indicators of an impairment exist. Evaluating goodwill for impairment involves the determination of the fair value of our reporting unit in which goodwill is recorded using a qualitative or quantitative analysis. If the fair value of the reporting unit exceeds its carrying value, goodwill is considered not impaired. If the carrying value of the reporting unit exceeds its fair value, we would record an impairment loss up to the difference between the carrying value and implied fair value.

We have an unconditional option to bypass the qualitative assessment in any period and proceed directly to performing the first step of the goodwill impairment test. For 2025, we elected to proceed directly to the step-one assessment which indicated that the fair value of our reporting unit substantially exceeded the carrying value.

Valuation of Long-lived Assets

We recorded impairment charges totaling $44.9 million related to property and equipment and finite-lived intangible assets which are included in “Impairment of long-lived assets” on our consolidated statements of operations and comprehensive loss for the year ended September 30, 2024.

During the year ended September 30, 2024, we identified an impairment indicator with respect to an asset group associated with our antibody discovery services product line (“Biopharma asset group”) due to lower than forecasted revenues. Therefore, we performed a recoverability test of long-lived assets by comparing the net book value of the Biopharma asset group, to the future undiscounted net cash flows attributable to such assets. We concluded that the carrying value of the asset group was not recoverable as it exceeded the future undiscounted cash flows the assets are expected to generate from the use and eventual disposition of the asset group.

To measure the impairment loss, we estimated the fair value of the Biopharma asset group by applying a discounted cash flow method. Calculating the fair value of an asset group involves making certain estimates and assumptions. These estimates and assumptions include, among others, the level and timing of revenues, operating expenses, working capital and discount rates, we believe to be consistent with the inherent risks associated with the Biopharma asset group, which was approximately 14%. Changes in these factors and assumptions used can materially affect the amount of impairment loss recognized in the period the asset group was considered impaired.

The implied allocated impairment loss to any individual asset within the long-lived asset group shall not reduce the carrying amount of that asset below its fair value. We estimated the fair value of the developed technology intangible asset and the customer relationships intangible assets using an excess earnings model (income approach). We estimated the fair value of the trade name intangible asset using a relief from royalty approach. Key assumptions include the level and timing of expected future revenue, conditions and demands specific to each intangible asset over its remaining useful life. The fair value of these intangible assets is primarily affected by the projected revenues, gross margins, operating expenses, and the anticipated timing of the projected income associated with each intangible asset coupled with the discount rates used to derive their estimated present values.

After consideration of the impairment charge recorded during the year ended September 30, 2024, the remaining carrying amount of long-lived assets within the Biopharma asset group was approximately $11.6 million, which primarily comprises of operating lease right-of-use assets.

Calculation of the fair value of investment in equities

On May 2, 2025, we measured the fair value of our investment in Series Seed-1 Preferred Stock of Atlas using the backsolve method with consideration for a lack of marketability. The backsolve method was used to solve for the implied total equity value based on the May 2025 financing by Atlas to third parties. Consideration was given to the rights and preferences of each of the classes of equity of Atlas and the expected time to a liquidity event. An option pricing allocation method, or OPM, was selected to allocate the total equity value. The OPM treats ordinary shares and preferred shares as call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various holders of a company’s securities changes.

56

Table of Contents

Equity investments held by the Company lack readily determinable fair values and therefore the securities are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar equity securities of the same issuer. We review the carrying value of our equity investments for impairment whenever events or changes in business circumstances indicate the carrying amount of such asset may not be fully recoverable. Impairments, if any, are based on the excess of the carrying amount over the recoverable amount of the asset.
