Basis of Presentation

The Company operates and controls all of the business and affairs of Topco LLC, and, through Topco LLC and its subsidiaries, conducts its business. Because we manage and operate the business and control the strategic decisions and day-to-day operations of Topco LLC, and also have a substantial financial interest in Topco LLC, we consolidate the financial results of Topco LLC, and a portion of our net loss is allocated to the non-controlling interests in Topco LLC held by MLSH 1.

The accompanying unaudited interim condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and accounts between the businesses comprising the Company have been eliminated in the accompanying consolidated financial statements. Certain prior period information has been reclassified to conform to the current period presentation.

Unaudited Interim Condensed Consolidated Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to Form 10-Q of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These unaudited condensed consolidated financial statements include all adjustments necessary to fairly state our financial position and the results of our operations and cash flows for interim periods in accordance with GAAP. All such adjustments are of a normal, recurring nature. Operating results for the three and six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2025 or for any future period.

The condensed consolidated balance sheet presented as of December 31, 2024 has been derived from the audited consolidated financial statements as of that date. The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain all information that is included in the annual financial statements and notes thereto of the Company. The condensed consolidated financial statements and notes included in this report should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”) filed with the SEC.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires the Company to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenue and expenses, and related disclosures. These estimates form the basis for judgments the Company makes about the carrying values of assets and liabilities that are not readily apparent from other sources. The Company bases its estimates and judgments on historical experience and on various other assumptions that the Company believes are reasonable under the circumstances. These estimates are based on management’s knowledge about current events and expectations about actions the Company may undertake in the future. Significant estimates include, but are not limited to, the measurement of right-of-use assets and lease liabilities and related incremental borrowing rate, the payable to related parties pursuant to the Tax Receivable Agreement (as defined in Note 11), the realizability of our net deferred tax assets, valuation of goodwill and intangible assets, valuation of assets acquired and liabilities assumed in business combinations, and determination of fair value of contingent consideration. Actual results could differ materially from those estimates.

Significant Accounting Policies

A description of the Company’s significant accounting policies is included in Note 1 of the Notes to the Consolidated Financial Statements included in the 2024 Form 10-K. There were no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2025.

Revenue Recognition

The Company generates revenue primarily from the sale of products, and to a much lesser extent, services in the fields of nucleic acid production and biologics safety testing. Products are sold primarily through a direct sales force and through distributors in certain international markets where the Company does not have a direct commercial presence.

Revenue is recognized when control of promised goods or services is transferred to a customer or distributor in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Distributors are the principal in all sales transactions with our customers. To determine revenue recognition for its arrangements with customers, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The majority of the Company’s contracts include only one performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition. The Company also recognizes revenue from other contracts that may include a combination of products and services, the provision of solely services, or from license fee arrangements which may be associated with the delivery of product. Where there is a combination of products and services, the Company accounts for the promises as individual performance obligations if they are concluded to be distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. As a practical expedient, we do not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below.

The Company recognizes revenue from sales to customers through distributors consistently with the policies and practices for direct sales to customers, as described above.

Nucleic Acid Production

Nucleic Acid Production revenue is generated from the manufacture and sale of highly modified, complex nucleic acid products to support the needs of our customers’ research, therapeutic and vaccine programs. The primary offering of products includes CleanCap®, mRNA, specialized oligonucleotides, and enzymes. Contracts typically consist of a single performance obligation. We also sell nucleic acid products for labeling and detecting proteins in cells and tissue samples research. The Company recognizes revenue from these products in the period in which the performance obligation is satisfied by transferring control to the customer or distributor. Revenue for nucleic acid catalog products is recognized at a single point in time, generally upon transferring control to the customer or distributor. Revenue for contracts for certain custom nucleic acid products, with an enforceable right to payment and a reasonable margin for work performed to date, is recognized over time, based on a cost-to-cost input method over the manufacturing period. Payments received from customers in advance of manufacturing their products is recorded as deferred revenue until the performance obligation is satisfied.

Biologics Safety Testing

The Company’s Biologics Safety Testing revenue is associated with the sale of host cell protein, bioprocess impurity detection, viral clearance prediction kits and associated products. We also enter into contracts that include custom antibody development, assay development, antibody affinity extraction and mass spectrometry services. These products and services enable the detection of impurities that occur in the manufacturing of biologic drugs and other therapeutics including cell and gene therapies. The Company recognizes revenue from the sale of kits and products in the period in which the performance obligation is satisfied by transferring control to the customer. Custom antibody development contracts consist of a single performance obligation, typically with an enforceable right to payment and a reasonable margin for work performed to date. Revenue is recognized over time based on a cost-to-cost input method over the contract term. Where an enforceable right to payment does not exist, revenue is recognized at a point in time when control is transferred to the customer. Assay development service contracts consist of a single performance obligation. Revenue is recognized at a point in time when a successful antigen test and report is provided to the customer. Affinity extraction, mass spectrometry and other analytical services, which generally occur over a short period of time, consist of a single performance obligation to perform the service and provide a summary report to the customer. Revenue is recognized upon delivery of the report to the customer or distributor.

The Company elected the practical expedient to not disclose the unfulfilled performance obligations for contracts with an original length of one year or less. The Company had no material unfulfilled performance obligations for contracts with an original length greater than one year for any period presented.

The Company accepts returns only if the products do not meet specifications and historically, the Company’s volume of product returns has not been significant. Further, no warranties are provided for promised goods and services other than assurance type warranties, which were not material for any period presented.

Revenue for an individual contract is recognized at the related transaction price, which is the amount the Company expects to be entitled to in exchange for transferring the products and/or services. The transaction price for product sales is calculated at the contracted product selling price. The transaction price for a contract with multiple performance obligations is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices for products are determined based on the prices charged to customers, which are directly observable. Standalone selling price of services are mostly based on time and materials. Generally, payments from customers are due when goods and services are transferred. As most contracts contain a single performance obligation, the transaction price is representative of the standalone selling price charged to customers. Revenue is recognized only to the extent that it is probable that a significant reversal of the cumulative amount recognized will not occur in future periods. Variable consideration has not been material to our consolidated financial statements.

Contract balances

Contract assets are generated when contractual billing schedules differ from revenue recognition timing and the Company records a contract receivable when it has an unconditional right to consideration. There wereno contract asset balances as of June 30, 2025 or December 31, 2024.

Contract liabilities include billings in excess of revenue recognized, such as customer deposits and deferred revenue. Customer deposits, which are included in accrued expenses and other current liabilities, are recorded when cash payments are received or due in advance of performance. Deferred revenue is recorded when the Company has unsatisfied performance obligations. Total contract liabilities were $2.6 million and $3.3 million as of June 30, 2025 and December 31, 2024, respectively. Contract liabilities are generally expected to be recognized into revenue within the next twelve months.

During the three and six months ended June 30, 2025, the Company recognized $0.6 million and $1.5 million, respectively, of revenue that was included in the contract liabilities balance of $3.3 million as of December 31, 2024. During the three and six months ended June 30, 2024, the Company didnot recognize a material amount of revenue that was included in the contract liabilities balance as of December 31, 2023.

Disaggregation of revenue

The following tables summarize the revenue by segment and region for the periods presented (in thousands):

Total revenue is attributed to geographic regions based on the bill-to location of the transaction. For all periods presented, the majority of our revenue was recognized at a point in time.

Non-Controlling Interests

Non-controlling interests represent the portion of profit or loss, net assets and comprehensive income or loss of our consolidated subsidiaries that is not allocable to the Company based on our percentage of ownership of such entities.

In November 2020, following the completion of a series of organizational transactions (the “Organizational Transactions”), we became the sole managing member of Topco LLC. As of June 30, 2025, we held approximately 56.6% of the outstanding LLC units of Topco LLC (“LLC Units”), and MLSH 1 held approximately 43.4% of the outstanding LLC Units. Therefore, we report non-controlling interests based on the percentage of LLC Units held by MLSH 1 on the condensed consolidated balance sheet as of June 30, 2025. Income or loss attributed to the non-controlling interest in Topco LLC is based on the LLC Units outstanding during the period for which the income or loss is generated and is presented on the condensed consolidated statements of operations and condensed consolidated statements of comprehensive loss.

MLSH 1 is entitled to exchange its LLC Units, together with an equal number of shares of our Class B common stock (together referred to as “Paired Interests”), for shares of our Class A common stock on aone-for-one basis or, at our election, for cash, from a substantially concurrent public offering or private sale (based on the price of our Class A common stock in such public offering or private sale). As such, future exchanges of Paired Interests by MLSH 1 will result in a change in ownership and reduce or increase the amount recorded as non-controlling interests and increase or decrease additional paid-in-capital when Topco LLC has positive or negative net assets, respectively.

Exchange of Topco LLC Units and Block Trade

In May 2024, MLSH 1 exchanged 8,409,946 LLC Units of Topco LLC (paired with an equal number of shares of our Class B common stock) for 8,409,946 shares of the Company’s Class A common stock. Upon receipt by the Company, the shares of our Class B common stock were subsequently cancelled and retired. Following the exchange, MLSH 1 and MLSH 2 sold an aggregate of 9,940,974 shares of our Class A common stock in a block trade (“May 2024 Block Trade”).

The Company did not receive any of the proceeds from the sale of shares of our Class A common stock by either MLSH 1 or MLSH 2, but did incur costs associated with the May 2024 Block Trade, which were not significant.

During the three and six months ended June 30, 2025, MLSH 1 did not exchange any Paired Interests.

Payments pursuant to Topco LLC Operating Agreement

Topco LLC is subject to an operating agreement put in place at the date of the Organizational Transactions (the “LLC Operating Agreement”). The LLC Operating Agreement includes a provision requiring cash distributions enabling its owners, including MLSH 1, to pay their taxes on income passing through from Topco LLC. No such cash distributions were made to MLSH 1 during the three and six months ended June 30, 2025. Cash distributions of $0.6 million for tax liabilities were made to MLSH 1 during each of the three and six months ended June 30, 2024.

Segment Information

The Company operates intwo reportable segments. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, allocates resources and assesses performance based upon discrete financial information at the segment level. Substantially all of our long-lived assets are located in the United States.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable primarily consist of amounts due from customers for product sales and services. The Company’s expected credit losses are developed using an estimated loss rate method that considers historical collection experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The estimated loss rates are applied to trade receivables with similar risk characteristics such as the length of time the balance has been outstanding, liquidity and financial position of the customer, and the geographic location of the customer. In certain instances, the Company may identify individual accounts receivable assets that do not share risk characteristics with other accounts receivable, in which case the Company records its expected credit losses on an individual asset basis.

The allowance for credit losses was approximately $0.8 million and $1.2 million as of June 30, 2025 and December 31, 2024, respectively. Write-offs of accounts receivable werenot significant during the three and six months ended June 30, 2025 and 2024. Recoveries werenot significant during the three and six months ended June 30, 2025, and there wereno recoveries during the three and six months ended June 30, 2024.

Goodwill represents the excess of consideration transferred over the estimated fair value of assets acquired and liabilities assumed in a business combination. Goodwill is not amortized but is reviewed for impairment. Goodwill is allocated to the Company’s reporting units, which are components of its business for which discrete cash flow information is available one level below its operating segment. The Company conducts a goodwill impairment analysis at least annually and more frequently if changes in facts and circumstances indicate that the fair value of the Company’s reporting units may be less than their respective carrying amount. In performing each annual impairment assessment and any interim impairment assessment, the Company determines if it should qualitatively assess whether it is more likely than not that the fair value of goodwill is less than its carrying amount (the qualitative impairment test). If it is more likely than not that the fair value of the reporting unit is less than its carrying amount, or if the Company elects not to perform the qualitative impairment test, the Company then performs a quantitative impairment test.

The quantitative impairment test is performed using a one-step process. The process is to compare the fair value of the reporting unit with its carrying amount. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of the reporting unit exceeds its fair value, goodwill of the reporting unit is impaired and an impairment loss is recognized in an amount equal to that excess up to the total amount of goodwill included in the reporting unit. During the three and six months ended 2025, the Company performed quantitative impairment tests and recorded goodwill impairment of $30.4 million and $42.9 million, respectively (see Note 3).

Fair Value of Financial Instruments

The Company defines fair value as the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The Company follows accounting guidance that has a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of the asset or liability as of the measurement date. Instruments with readily available actively quoted prices, or for which fair value can be measured from actively quoted prices in an orderly market, will generally have a higher degree of market price transparency and a lesser degree of judgment used in measuring fair value. The three levels of the hierarchy are defined as follows:

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets;

Level 2—Include other inputs that are directly or indirectly observable in the marketplace; and

Level 3—Unobservable inputs which are supported by little or no market activity.

As of June 30, 2025 and December 31, 2024, the fair values of cash and cash equivalents, which consisted primarily of money market funds, time and demand deposits, trade accounts receivable, net, and trade accounts payable, approximated their carrying amounts due to the short maturities of these instruments. As of June 30, 2025 and December 31, 2024, the fair value of the Company’s long-term debt approximated its carrying value, excluding the effect of unamortized debt discount, as it is based on borrowing rates currently available to the Company for debt with similar terms and maturities (Level 2 inputs). See Note 4 for the Company's financial assets and liabilities that are measured at fair value on a recurring basis.

Acquisitions

The Company evaluates mergers, acquisitions and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or an acquisition of assets. The Company first identifies the acquired entity by determining if the target is a legal entity or a group of assets or liabilities. If control over a legal entity is being evaluated, the Company also evaluates if the target is a variable interest or voting interest entity. For acquisitions of voting interest entities, the Company applies a screen test to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen test is met, the transaction is accounted for as an acquisition of assets. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs which would meet the definition of a business.

The Company accounts for its business combinations using the acquisition method of accounting which requires that the assets acquired and liabilities assumed of acquired businesses be recorded at their respective fair values at the date of acquisition. The purchase price, which includes the fair value of consideration transferred, is attributed to the fair value of the assets acquired and liabilities assumed. The purchase price may also include contingent consideration. The Company assesses whether such contingent consideration is subject to liability classification and fair value measurement or meets the definition of a derivative. Contingent consideration liabilities are recognized at their estimated fair value on the acquisition date. Contingent consideration meeting the criteria to be classified as equity in the consolidated balance sheets is not remeasured, as subsequent settlement is recorded within stockholders’ equity. Contingent consideration arrangements that are determined to be compensatory in nature are recognized as post combination expense in our consolidated statements of operations ratably over the implied service period beginning in the period it becomes probable such amounts will become payable. The excess of the purchase price of the acquisition over the fair value of the identifiable net assets of the acquiree is recorded as goodwill. The fair value of assets acquired and liabilities assumed in certain cases may be subject to revision based on the final determination of fair value during a period of time not to exceed twelve months from the acquisition date. The results of acquired businesses are included in the Company’s consolidated financial statements from the date of acquisition. Transaction costs directly attributable to acquired businesses are expensed as incurred.

Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates, including the selection of valuation methodologies and assumptions about future net cash flows, discount rates and selection of comparable companies. Each of these factors can significantly affect the value attributed to the identifiable intangible asset acquired in a business combination.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and accounts receivable. The Company maintains the majority of its cash balances at multiple financial institutions that management believes are of high-credit-quality and financially stable. Cash is deposited with major financial institutions in excess of Federal Deposit Insurance Corporation insurance limits. The Company believes it is not exposed to significant credit risk due to the financial strength of the depository institutions in which the cash is held. The Company provides credit, in the normal course of business, to international and domestic distributors as well as certain customers, which are geographically dispersed. The Company attempts to limit its credit risk by performing ongoing credit evaluations of its customers and maintaining adequate allowances for potential credit losses.

The following table summarizes revenue from each of our customers who individually accounted for 10% or more of our total revenue or accounts receivable for the periods presented:

*Less than 10%

For the three and six months ended June 30, 2024, all of the revenue recorded for Nacalai USA, Inc. was generated by the Nucleic Acid Production segment.

2. Acquisitions

Molecular Assemblies

On January 23, 2025, the Company completed the acquisition of assets from Molecular Assemblies, Inc. (“Molecular”) expanding TriLink Biotechnologies, LLC’s (“TriLink”) ability to enable customers to develop next-generation mRNA and clustered regularly interspaced short palindromic repeats nucleic acid-based therapies. The acquisition will complement the Company’s product portfolio and manufacturing capabilities. The acquisition will vertically integrate the Company’s supply chain and expand its product offerings for inputs used in the development of therapeutics and vaccines.

The Company acquired assets from Molecular for a total purchase consideration of $11.2 million. The total cash consideration of $9.2 million was paid using existing cash on hand. The transaction was accounted for as an acquisition of a business as the assets acquired from Molecular consisted of multiple types of long-lived assets, as well as inputs and processes applied to those inputs that had the ability to contribute to the creation of outputs.

For the three and six months ended June 30, 2025, the Company incurred $0.1 million and $0.7 million, respectively, in transaction costs associated with the acquisition of assets from Molecular, which were recorded within selling, general and administrative expenses in the condensed consolidated statements of operations.

The acquisition date fair value of consideration transferred to acquire the assets from Molecular consisted of the following (in thousands):

Pursuant to the Molecular Assemblies Asset Purchase Agreement (the “Molecular APA”), the Company maintained an indemnity and adjustment holdback of $2.0 million for the purpose of providing security against any adjustments to the amounts at closing, which has been recorded within accrued expenses and other current liabilities on the condensed consolidated balance sheet as of June 30, 2025. The indemnity holdback period extends to the later ofsix months from the closing date or when Molecular meets certain conditions, as defined in the Molecular APA, related to the wind down of Molecular.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands):

The acquisition was accounted for under the acquisition method of accounting, and therefore, the total purchase price was allocated to the identifiable tangible and intangible assets acquired and the liabilities assumed based on their respective fair values as of the acquisition date. Purchase consideration in excess of the amounts recognized for the net assets acquired was recognized as goodwill. Goodwill is primarily attributable to expanded synergies expected from the acquisition associated with vertical supply integration. All of the goodwill acquired in connection with the acquisition of Molecular was allocated to the Company’s Nucleic Acid Production segment. All of the goodwill recognized is expected to be deductible for income tax purposes.

The following table summarizes the estimated fair values of identifiable intangible assets acquired from Molecular as of the date of acquisition and their estimated useful life:

The developed technology intangible asset is related to its patented manufacturing process capability to both synthesize enzyme oligonucleotides and achieve quality standards. The fair value of the intangible asset was based on projected revenues for the acquired assets and was estimated using an income approach, specifically the multi-period excess earnings method for developed technology. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. The estimated fair value was developed by discounting future net cash flows to their present value at market-based rates of return utilizing Level 3 inputs. The useful lives for these intangible assets were determined based upon the remaining period for which the assets were expected to contribute directly or indirectly to future cash flows. Key quantitative assumptions used in the determination of fair value of the developed technology intangible included revenue growth rates ranging from 3.0% to 118.1%, a discount rate of 11.5%, and an assumed technical obsolescent curve of 5.0%.

The fair value of equipment was based on both cost and market approaches utilizing Level 2 inputs. The carrying value of the remaining assets acquired or liabilities assumed was estimated to equal their fair values based on their short-term nature. These estimates were based on assumptions that the Company believes to be reasonable; however, actual results may differ from these estimates.

Revenue and earnings from the assets acquired from Molecular included in the Company’s condensed consolidated statements of operations since the date of acquisition were immaterial.

No proforma revenue or earnings information for the three and six months ended June 30, 2025 and 2024 has been presented as the impact was determined not to be material to the Company’s condensed consolidated revenues and net loss for the respective periods.

Officinae Bio

On February 21, 2025, the Company completed the acquisition of the DNA and RNA business of Officinae Bio (“Officinae”), a privately held technology company with a proprietary digital platform designed with artificial intelligence and machine learning capabilities to support the biological design of therapeutics. The acquisition will complement the Company’s product portfolio and manufacturing capabilities by assisting TriLink customers to design and purchase the Company’s products.

The Company acquired Officinae for a total purchase consideration of $15.1 million. The total cash consideration of $9.9 million was paid using existing cash on hand. As a result of the acquisition, we own all the outstanding interest in Officinae. The transaction was accounted for as an acquisition of a business as Officinae consisted of inputs and processes applied to those inputs that had the ability to contribute to the creation of outputs.

For the three and six months ended June 30, 2025, the Company incurred $0.3 million and $0.5 million, respectively, in transaction costs associated with the acquisition of Officinae, which were recorded within selling, general and administrative expenses in the condensed consolidated statements of operations.

The acquisition date fair value of consideration transferred to acquire Officinae consisted of the following (in thousands):

Pursuant to the Officinae Securities Purchase Agreement (the “Officinae SPA”) between the Company and sellers of Officinae, additional payments to the sellers of Officinae are dependent upon certain milestones and meeting or exceeding defined revenue targets through December 31, 2028 (the “Officinae Contingent Consideration”). The Officinae SPA provides for a total maximum Officinae Contingent Consideration of $35.0 million, with $5.0 million of such contingent consideration payable in cash upon the achievement of a certain integration milestone (the “Milestone Consideration”) and up to an additional $30.0 million payable in a mix of cash and shares of the Company’s Class A common stock, such mix to be mutually agreed at the time of any payout, upon the achievement of certain revenue and license milestones (the “Earnout Considerations”). The Milestone Consideration was recorded as contingent consideration and was included as part of the purchase consideration. The acquisition date estimated fair value for the Milestone Consideration of $4.8 million was developed at a 100.0% probability of achievement and by discounting future net cash flows to their present value at a discount rate of 7.3%, which is a Level 3 input (see Note 4). The Earnout Considerations had no probability of achievement at the acquisition date and at June 30, 2025, the value was not measurable.

Upon closing of the acquisition, the Company deferred $0.3 million of the purchase price to cover potential working capital adjustments. During the three months ended June 30, 2025, this amount was fully paid.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands):

The acquisition was accounted for under the acquisition method of accounting, and therefore, the total purchase price was allocated to the identifiable tangible and intangible assets acquired and the liabilities assumed based on their respective fair values as of the acquisition date. Purchase consideration in excess of the amounts recognized for the net assets acquired was recognized as goodwill. Goodwill is primarily attributable to expanded synergies expected from the acquisition associated with integrating Officinae’s technology platform and manufacturing processes with the Company’s product offerings and assembled workforce. All of the goodwill acquired in connection with the acquisition of Officinae was allocated to the Company’s Nucleic Acid Production segment. None of the goodwill recognized is expected to be deductible for income tax purposes.

The following table summarizes the estimated fair values of Officinae’s identifiable intangible assets as of the date of acquisition and their estimated useful lives:

The customer relationships intangible assets are related to Officinae’s customer loyalty and customer relationships. The developed technology intangible asset is related to Officinae’s proprietary design and e-commerce platform to support the biological design of therapeutics and its unique manufacturing process optimizations. The fair value of these intangible assets was based on Officinae’s projected revenues and revenues for orders placed using the platform, and was estimated using an income approach, specifically the multi-period excess earnings method for developed technology and the distributor method for customer relationships. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. The estimated fair value was developed by discounting future net cash flows to their present value at market-based rates of return utilizing Level 3 inputs. The useful lives for these intangible assets were determined based upon the remaining period for which the assets were expected to contribute directly or indirectly to future cash flows. Key quantitative assumptions used in the determination of fair value of the developed technology intangible included revenue growth rates ranging from 3.0% to 89.3%, a discount rate of 19.0%, and a technical obsolescent curve of 5.0% in the first five years and 10.0% thereafter.

The carrying value of the remaining assets acquired or liabilities assumed was estimated to equal their fair values based on their short-term nature. These estimates were based on assumptions that the Company believes to be reasonable; however, actual results may differ from these estimates.

Revenue and earnings from Officinae included in the Company’s condensed consolidated statements of operations since the date of acquisition were immaterial.

No proforma revenue or earnings information for the three and six months ended June 30, 2025 and 2024 has been presented as the impact was determined not to be material to the Company’s condensed consolidated revenues and net loss for the respective periods.

3. Goodwill and Intangible Assets

The following table summarizes the activity in the Company’s goodwill by segment for the six months ended June 30, 2025 (in thousands):

(1)The Nucleic Acid Production segment had accumulated goodwill impairment of $209.0 million and $166.2 million as of June 30, 2025 and December 31, 2024, respectively.

(2)The Biologics Safety Testing segment hadno accumulated goodwill impairment as of June 30, 2025 and December 31, 2024.

As of June 30, 2025 and December 31, 2024, the Company hadfour reporting units, three of which are contained in the Nucleic Acid Production segment.

During the first quarter of 2025, the Company recorded goodwill of $3.4 million in connection with the acquisition of assets from Molecular, and goodwill of $8.8 million in connection with the acquisition of Officinae (see Note 2). These acquisitions were included within the TriLink reporting unit.

In connection with preparing its financial statements for the first quarter of 2025, the Company performed a qualitative goodwill impairment analysis on each of itsfour reporting units and concluded that it was more likely than not that the fair value of goodwill exceeded its carrying value forthree of the reporting units and no further testing was required. As a result, no impairment was recorded for these three reporting units. The Company performed a quantitative impairment test on the TriLink reporting unit in response to impairment indicators identified during the first quarter of 2025. The indicators of impairment primarily related to the Company’s long-term forecast which reflected lower projected near term revenues due to lower demand in research and discovery products within the TriLink reporting unit and slower than expected transition to new mRNA clinical trials as customers prioritize existing programs and more conservatively invest in new programs as the result of macroeconomic pressures. The Company performed the impairment test using a combination of the income and the market approach to determine whether the fair value of the TriLink reporting unit was less than its carrying value. The income approach utilizes a discounted cash flow model with inputs developed using both internal and market-based data, while the market approach utilizes comparable company information. The significant assumptions in the discounted cash flow models included, but are not limited to, discount rates, revenue projections, revenue growth rate assumptions (including terminal growth rates) and EBITDA margins. These assumptions were developed in light of then-current market conditions and future expectations which included, but were not limited to, new product and service developments, impact of competition and future economic conditions. These estimates and assumptions represented a Level 3 measurement because they were supported by little or no market activity and reflected our own assumptions in measuring fair value. Based on its interim quantitative assessment, the Company concluded that the TriLink reporting unit had a carrying value that exceeded its estimated fair value. As a result, during the first quarter of 2025, the Company recorded goodwill impairment of $12.4 million on the condensed consolidated statements of operations, which represented the entire remaining goodwill balance for the TriLink reporting unit.

In connection with preparing its financial statements for the quarter ended June 30, 2025, the Company performed a qualitative goodwill impairment analysis on each of thethree reporting units with goodwill balances. Fortwo of the reporting units (the Cygnus reporting unit and the Glen reporting unit), the Company concluded that it was more likely than not that the fair value of goodwill exceeded its carrying value for these reporting units and no further testing was required. As a result, no goodwill impairment was recorded for thesetwo reporting units. The Company performed a quantitative impairment test on the Alphazyme reporting unit in response to impairment indicators identified during the Company’s forecast process. As of June 30, 2025, the Company’s long-term forecast reflected lower projected revenues within its Nucleic Acid Production business due to lower anticipated demand in enzyme products. The Company performed the June 30, 2025 impairment test using a combination of the income approach and the market approach to determine whether the fair value of the Alphazyme reporting unit was less than its carrying value. The income approach utilizes a discounted cash flow model with inputs developed using both internal and market-based data, while the market approach utilizes comparable company information. The significant assumptions in the discounted cash flow model include, but are not limited to, discount rates, revenue, revenue growth rate assumptions (including terminal growth rates) and EBITDA margin. The selected discount rate was 19.5%, which was determined using a weighted average cost of capital specific to the Alphazyme reporting unit and other market and industry data. These assumptions were developed in light of current market conditions and future expectations which include, but were not limited to, new product and service developments, the impact of competition and future economic conditions. These estimates and assumptions represent a Level 3 measurement because they were supported by little or no market activity and reflected the Company’s own assumptions in measuring fair value. Based on its quantitative assessment, the Company concluded that the Alphazyme reporting unit had a carrying value that exceeded its estimated fair value. As a result, the Company recorded goodwill impairment of $30.4 million on the condensed consolidated statements of operations, which represented the entire remaining goodwill balance for the Alphazyme reporting unit.

Intangible Assets

In conjunction with the goodwill impairment tests performed in the first quarter of 2025 for TriLink and the second quarter of 2025 for Alphazyme, the Company also evaluated the recoverability of its long-lived assets (including finite-lived intangible assets). The Company performed the impairment tests by comparing the respective carrying value of the assets to the current and expected future cash flows, on an undiscounted basis, to be generated from such assets. Based on the impairment tests, it was determined that the carrying value of the asset groups did not exceed their respective current and expected future cash flows, on an undiscounted basis. No impairment for long-lived assets (including finite-lived intangible assets) was recorded as a result of these evaluations.

Intangible assets are being amortized on a straight-line basis, which reflects the expected pattern in which the economic benefits of the intangible assets are being obtained, over an estimated useful life ranging from 3 to 14 years.

The following are components of finite-lived intangible assets and accumulated amortization as of the periods presented (in thousands):

(1)Certain intangible assets are denominated in currencies other than U.S. dollar; therefore, their gross and net carrying values are subject to foreign currency movements.

During the first quarter of 2025, the Company recorded intangible assets of $3.2 million in connection with the acquisition of assets from Molecular, and intangible assets of $8.2 million in connection with the acquisition of Officinae (see Note 2).

The Company recognized $6.6 million and $13.0 million of amortization expense from intangible assets directly linked with revenue-generating activities within cost of revenue in the condensed consolidated statements of operations for the three and six months ended June 30, 2025, respectively. The Company recognized $6.2 million and $12.4 million of amortization expense from intangible assets directly linked with revenue-generating activities within cost of revenue in the condensed consolidated statements of operations for the three and six months ended June 30, 2024, respectively.

Amortization expense for intangible assets that are not directly related to revenue-generating activities of $0.6 million and $1.2 million was recorded as selling, general and administrative expenses for the three and six months ended June 30, 2025, respectively. Amortization expense for intangible assets that are not directly related to revenue-generating activities of $0.7 million and $1.3 million was recorded as selling, general and administrative expenses for the three and six months ended June 30, 2024, respectively.

As of June 30, 2025, the estimated future amortization expense for finite-lived intangible assets was as follows (in thousands):

4. Fair Value Measurements

The following tables summarize the Company’s financial assets and liabilities that are measured at fair value on a recurring basis by level within the fair value hierarchy as of the periods presented (in thousands):

Contingent Consideration

Alphazyme

In connection with the acquisition of Alphazyme, LLC (“Alphazyme”), which was completed in January 2023, the Company was initially required to make contingent payments to the sellers of Alphazyme of up to $75.0 million (the “Performance Payments”), subject to Alphazyme achieving certain revenue thresholds during each of the fiscal years 2023 through 2025. The preliminary fair value of the liability for the contingent consideration recognized upon the completion of the acquisition as part of the purchase accounting opening balance sheet was $5.3 million. The preliminary fair value of the contingent consideration was determined using a Monte-Carlo simulation-based model discounted to present value. Assumptions used to determine the fair value were expected revenue, a discount rate of 17.8% and various probability factors. The ultimate settlement of the contingent consideration could deviate from current estimates based on actual revenues. The contingent consideration consists ofthree Performance Payments for each of thethree annual performance periods, with the first and second payments (to the extent earned) due in 2024 and 2025, respectively. For the first and second performance periods which ended on December 31, 2023 and 2024, respectively, it was determined that the defined revenue targets were not achieved. Consequently, no Performance Payments were made to the sellers of Alphazyme for the first and second performance periods. As of June 30,

2025, the Company may be required to make Performance Payments to the sellers of Alphazyme of up to $25.0 million for the third performance period; however, based on Alphazyme’s current revenue expectations, no such payment is expected to be made.

This contingent consideration liability, which hadno fair value as of June 30, 2025, is considered to be a Level 3 financial liability that is remeasured each reporting period. Changes in fair value of contingent consideration are recognized as a gain or loss and recorded within change in estimated fair value of contingent consideration in the condensed consolidated statements of operations. During the three and six months ended June 30, 2024, the Company recorded a $1.2 million decrease in the estimated fair value of contingent consideration. This was due to a change in estimate associated with the expected achievement of the Alphazyme revenue thresholds that would require the Company to make a contingent consideration payment under the Alphazyme Securities Purchase Agreement.

Officinae

In connection with the acquisition of Officinae (see Note 2), the Company is required to make contingent payments to the sellers of $5.0 million payable in cash upon the achievement of a certain integration milestone. The preliminary fair value of the liability for the contingent payments recognized upon the acquisition as part of the purchase accounting opening balance sheet was $4.8 million. The estimated fair value was developed at a 100.0% probability of achievement and by discounting future net cash flows to their present value at a discount rate of 7.3%. The ultimate settlement of the contingent consideration could deviate from current estimates based on the actual results of these financial measures.

This contingent consideration liability is considered to be a Level 3 financial liability that is remeasured each reporting period. Changes in fair value of contingent consideration are recognized as a gain or loss and recorded within change in estimated fair value of contingent consideration in the condensed consolidated statements of operations. During the three and six months ended June 30, 2025, the Company recorded a $0.1 million increase in the estimated fair value of contingent consideration due to a change in its present value.

The following table provides a reconciliation of liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the period presented (in thousands):

6. Government Assistance

Cooperative Agreement

TriLink has a cooperative agreement (the “Cooperative Agreement”) with the U.S. Department of Health and Human Services (“HHS”), to advance the development of domestic manufacturing capabilities and to expand TriLink’s domestic production capacity in its San Diego manufacturing campus (the “Flanders San Diego Facility”) for products critical to the development and manufacture of mRNA vaccines and therapeutics. The Flanders San Diego Facility consists oftwo buildings (“Flanders I” and “Flanders II”), however, the Cooperative Agreement is exclusively involved in Flanders I.

The Cooperative Agreement requires the Company to provide the U.S. Government with conditional priority access and certain preferred pricing obligations for a 10-year period from the completion of the construction project for the production of a medical countermeasure (or a component thereof) that the Company manufactures in the Flanders San Diego Facility during a declared public health emergency.

Pursuant to certain requirements, TriLink was awarded an amount equal to $38.8 million or 50% of the construction and validation costs currently budgeted for the Flanders San Diego Facility. The contract period of performance is May 2022 through March 2035, which is the effective date of the Cooperative Agreement through the anticipated expiration of the 10-year conditional priority access period. Amounts reimbursed are subject to audit and may be recaptured by the HHS in certain circumstances.

During the six months ended June 30, 2025, the Company received $0.7 million ofreimbursements under the Cooperative Agreement, with an equal offset recorded to property and equipment on the condensed consolidated balance sheets. During the three and six months ended June 30, 2024, the Company received $3.4 million and $4.8 million, respectively, of reimbursements under the Cooperative Agreement, with equal offsets recorded to property and equipment on the condensed consolidated balance sheets. By the end of the first quarter of 2025, the Company had utilized and received the full amount of the award.

7. Commitments and Contingencies

Unconditional Purchase Obligations

In the ordinary course of business, we enter into certain unconditional purchase obligations with our suppliers. These are agreements to purchase products and services that are enforceable, legally binding, and specify terms that include provisions with respect to quantities, pricing and timing of purchases.

Amounts purchased under these obligations totaled $1.9 million and $3.0 million for the three and six months ended June 30, 2025, respectively. Amounts purchased under these obligations totaled $1.6 million and $3.5 million for the three and six months ended June 30, 2024, respectively.

As of June 30, 2025, future minimum commitments under these obligations totaled $0.9 million which relate to the six months ending December 31, 2025 and the year ending December 31, 2026.

Legal Proceedings

In addition to the proceedings described below, the Company is involved in various legal proceedings arising in the normal course of business. The Company accrues for a loss contingency when it determines that it is probable, after consultation with counsel, that a liability has been incurred and the amount of such loss can be reasonably estimated. As of the date of this report, none of such loss contingencies, either individually or in the aggregate, are expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

On March 3, 2025, a purported stockholder filed a putative class action lawsuit against the Company and certain former officers of the Company in the United States District Court for the Southern District of California, captioned Nelson v. Maravai Lifesciences Holdings, Inc., et al. (the “Securities Class Action”). The Securities Class Action generally alleges that the defendants violated federal securities laws by making allegedly materially false or misleading statements about the Company’s business, operations, and prospects, and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated under the Exchange Act. The plaintiff seeks to represent a putative class of investors who purchased or acquired the Company’s stock between August 7, 2024 and February 24, 2025. The Securities Class Action seeks, among other things, compensatory damages and attorneys’ fees and costs. On July 29, 2025, the lead plaintiff filed an amended complaint. Defendants intend to file a motion to dismiss the amended complaint on or around September 29, 2025.

On June 20, 2025, a purported stockholder derivative lawsuit was filed in the United States District Court for the Southern District of California for the benefit of the Company as the nominal defendant, captioned Mercer v. Martin, et al. (the “Mercer Derivative Action”). The plaintiff alleges breaches of fiduciary duties and violations of Section 14(a) of the Exchange Act by certain past and present officers and directors of the Company. The Mercer Derivative Action seeks, among other things, corporate governance reforms, restitution to be paid to the Company, and attorneys’ fees. On July 18, 2025, the court stayed the Mercer Derivative Action until October 1, 2025, or until 14 days after a ruling on the anticipated motion to dismiss in the Securities Class Action so long as the anticipated motion is filed before October 1, 2025. On July 16, 2025, another purported stockholder filed a substantially similar derivative lawsuit in the United States District Court for the Southern District of California, captioned Husurianto v. Martin, et al. (collectively with the Mercer Derivative Action, the “Derivative Actions”). On July 25, 2025, the parties moved to consolidate the Derivative Actions.

The Company intends to vigorously defend the Securities Class Action and the Derivative Actions. Currently, the Company cannot reasonably estimate any potential loss or range of loss that may arise from the Securities Class Action or the Derivative Actions.

Indemnification Agreements

In the ordinary course of business, we may provide indemnification of varying scope and terms to vendors, lessors, customers and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties, and losses arising from breach of representations, warranties and covenants to counterparties set forth in agreements with such parties. We have also agreed to indemnify our directors and officers to the maximum extent permitted under applicable state laws pursuant to standard director and officer indemnification agreements and our corporate charter and bylaws. The maximum potential amount of future payments that we could be required to make under these indemnification agreements is, in many cases, unlimited. We have not incurred any material costs as a result of such indemnifications and are not currently aware of any indemnification claims.

8. Long-Term Debt

Credit Agreement

Maravai Intermediate Holdings, LLC, a wholly-owned subsidiary of Topco LLC, along with certain of its subsidiaries are parties to a credit agreement (as amended, the “Credit Agreement”), which provides for a $600.0 million term loan facility, maturing October 2027 (the “Term Loan”), and a $167.0 million revolving credit facility, maturing October 2029 (subject to springing maturity provisions based on the maturity of the Term Loan) (the “Revolving Credit Facility”). Borrowings under the Credit Agreement bear interest at a variable rate based on Term Secured Overnight Financing Rate (“SOFR”) plus an applicable interest rate margin.

As of June 30, 2025, the effective interest rate on the Term Loan was 7.27% per annum.

The Revolving Credit Facility also provides availability for the issuance of letters of credit up to an aggregate limit of $20.0 million. As of June 30, 2025, the Company had a $0.5 million outstanding letter of credit as security for a lease agreement, which reduced the availability for the future issuance of letters of credit under the Revolving Credit Facility to $19.5 million.

Borrowings under the Credit Agreement are unconditionally guaranteed by Topco LLC, together with the existing and future material domestic subsidiaries of Topco LLC (subject to certain exceptions), as specified in the respective guaranty agreements. Borrowings under the Credit Agreement are also secured by a first-priority lien and security interest in substantially all of the assets (subject to certain exceptions) of existing and future material domestic subsidiaries of Topco LLC that are loan parties.

The Term Loan requires mandatory quarterly principal payments of $1.4 million which began in March 2022, and all remaining outstanding principal is due on maturity in October 2027.

As of June 30, 2025, unamortized debt issuance costs totaled $1.6 million and are recorded within other assets on the accompanying condensed consolidated balance sheet as there isno borrowing balance outstanding related to the Revolving Credit Facility.

The Credit Agreement requires prepayments on the Term Loan principal for certain excess cash flow, subject to certain step-downs based on the Company’s first lien net leverage ratio for the fiscal year. The excess cash flow prepayment is reduced to 25% or 0% of the calculated excess cash flow if the Company’s first lien net leverage ratio was equal to or less than 4.75:1.00 or 4.25:1.00, respectively, however, no prepayment is required to the extent excess cash flow calculated for the fiscal year is equal to or less than $10.0 million. As of June 30, 2025, the Company’s first lien net leverage ratio was negative and its excess cash flow was less than $10.0 million.

The Credit Agreement contains certain covenants, including, among other things, covenants limiting our ability to incur or prepay certain indebtedness, pay dividends or distributions, dispose of assets, engage in mergers and consolidations, make acquisitions or other investments and make changes to the nature of the business. Additionally, the Credit Agreement requires us to maintain a certain net leverage ratio if the outstanding debt balance on the Revolving Credit Facility exceeds 35.0% of the aggregate amount of available credit of $167.0 million, or $58.5 million. The Company was in compliance with these covenants as of June 30, 2025.

Interest Rate Cap

The Company was a party to an interest rate cap agreement to manage a portion of its variable interest rate risk on its outstanding long-term debt. Under the terms of the contract, the Company was entitled to receive from the counterparty, at each calendar quarter end, the amount, if any, by which a specified defined floating market rate exceeded the cap strike interest rate, applied to the contract’s notional amount of $500.0 million. The floating rate of interest was reset at the end of each three-month period. The contract expired on January 19, 2025.

The interest rate cap agreement was not designated as a hedging relationship and was recognized on the condensed consolidated balance sheet at fair value of $1.4 million, within prepaid expenses and other current assets, as of December 31, 2024. Changes in fair value were recognized within interest expense in the condensed consolidated statements of operations. Proceeds from the interest rate cap agreement were reflected in cash flows provided by (used in) financing activities in the condensed consolidated statements of cash flows.

The Company’s long-term debt consisted of the following as of the periods presented (in thousands):

There wereno borrowing balances outstanding on the Company’s Revolving Credit Facility as of June 30, 2025 and December 31, 2024.

As of June 30, 2025, the aggregate future principal maturities of the Company’s debt obligations based on contractual due dates, were as follows (in thousands):

9. Net Loss Per Class A Common Share Attributable to Maravai LifeSciences Holdings, Inc.

Basic net loss per Class A common share has been calculated by dividing net loss for the period, adjusted for net loss attributable to non-controlling interests, by the weighted average number of Class A common shares outstanding during the period. In periods in which the Company reports a net loss attributable to Maravai LifeSciences Holdings, Inc., diluted net loss per Class A common share attributable to the Company is the same as basic net loss per Class A common share attributable to the Company, since dilutive equity instruments are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to Maravai LifeSciences Holdings, Inc. during each of the three and six months ended June 30, 2025 and 2024.

The following table presents the computation of basic and diluted net loss per Class A common share attributable to the Company for the periods presented (in thousands, except per share amounts):

Shares of Class B common stock do not share in the earnings or losses of the Company and are therefore not participating securities. As such, a separate presentation of basic and diluted net loss per share for Class B common stock under the two-class method has not been presented.

The following table presents potentially dilutive securities excluded from the computation of diluted net loss per share for the periods presented because their effect would have been anti-dilutive for the periods presented (in thousands):

Shares underlying contingently issuable awards that have not met the necessary conditions as of the end of a reporting period are not included in the calculation of diluted net loss per Class A common share attributable to the Company for that period. The Company had contingently issuable performance stock units outstanding that did not meet the market and performance conditions as of June 30, 2025 and 2024, and therefore, were excluded from the calculation of diluted net loss per Class A common share attributable to the Company. The maximum number of potentially dilutive shares that could be issued upon vesting for such awards was 3.3 million as of June 30, 2025 and was an insignificant amount as of June 30, 2024. These share amounts were also excluded from the potentially dilutive securities in the table above.

10. Income Taxes

We are subject to U.S. federal, state and foreign income taxes with respect to our allocable share of any taxable income or loss of Topco LLC, as well as any stand-alone income or loss we generate. Topco LLC is organized as a limited liability company and treated as a partnership for U.S. federal tax purposes and generally does not pay income taxes on its taxable income in most jurisdictions. Instead, Topco LLC’s taxable income or loss is passed through to its members, including us.

The following table summarizes the Company’s income tax benefit and effective tax rate for the periods presented (in thousands, except percentages):

The Company’s effective tax rate of 5.8% and 3.3% for the three and six months ended June 30, 2025, respectively, differed from the U.S. federal statutory income tax rate of 21.0%, primarily due to loss associated with the non-controlling interest, the valuation allowance recorded against the Company’s deferred tax assets, and the release of a previous uncertain tax position due to statute expiration.

The Company’s effective tax rate of 11.7% and 5.0% for the three and six months ended June 30, 2024, respectively, differed from the U.S. federal statutory income tax rate of 21.0%, primarily due to loss associated with the non-controlling interest, the valuation allowance recorded against the Company’s deferred tax assets, and the release of a previous uncertain tax position due to statute expiration.

As of June 30, 2025 and December 31, 2024, the Company had $0.4 million and $3.6 million, respectively, of unrecognized tax benefits, all of which would affect the effective tax rate if recognized. The Company does not expect to recognize a material change to unrecognized tax benefits in the next twelve months. The Company recognizes interest related to uncertain tax benefits as a component of income tax expense (benefit), which was immaterial during each of the three and six months ended June 30, 2025 and 2024.

Tax Distributions to Topco LLC’s Owners

The LLC Operating Agreement has numerous provisions related to allocations of income and loss, as well as timing and amounts of distributions to its unit holders. This agreement also includes a provision requiring cash distributions enabling its owners to pay their taxes on income passing through from Topco LLC. These tax distributions are computed based on an assumed income tax rate equal to the sum of (i) the maximum combined marginal U.S. federal and state income tax rate applicable to an individual and (ii) the net investment income tax. The assumed income tax rate currently totals 46.7%, which may increase to 54.1% in certain cases where the qualified business income deduction is unavailable.

In addition, Topco LLC is subject to entity level taxation in certain states and certain of its subsidiaries are subject to entity level U.S. and foreign income taxes. As a result, the accompanying condensed consolidated statements of operations include income tax expense related to those states and to U.S. and foreign jurisdictions where Topco LLC or any of our subsidiaries are subject to income tax.

During each of the three and six months ended June 30, 2025, Topco LLC didnot pay any tax distributions to its unit holders. During each of the three and six months ended June 30, 2024, Topco LLC paid tax distributions of $1.3 million to its unit holders, including $0.7 million to the Company.

As of June 30, 2025, no amounts for tax distributions had been accrued.

Recent Legislation

On July 4, 2025, a budget and reconciliation bill commonly referred to as the One Big Beautiful Bill Act ("OBBBA") was enacted into law in the U.S. The OBBBA includes significant provisions, such as the extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business expenses, including research and development costs. The OBBBA has varying effective dates, with certain provisions effective in 2025 and others with multiple effective dates through 2027. We are currently assessing the impact of these provisions on our consolidated financial statements.

11. Related Party Transactions

MLSH 1’s majority owner is GTCR, LLC (“GTCR”). The Company’s General Counsel is an officer of MLSH 1 and MLSH 2.

Payable to Related Parties Pursuant to the Tax Receivable Agreement

We are a party to a TRA with MLSH 1 and MLSH 2. The TRA provides for the payment by us to MLSH 1 and MLSH 2, collectively, of 85% of the amount of certain tax benefits, if any, that we actually realize, or in some circumstances are deemed to realize, as a result of the Organizational Transactions, our initial public offering (“IPO”) and any subsequent purchases or exchanges of LLC Units. The Company expects to benefit from the remaining 15% of any cash tax savings that it realizes.

We recognize the amount of TRA payments expected to be paid within the next 12 months and classify this amount as current. This determination is based on our taxable income for the year ended December 31, 2024. As of June 30, 2025, there wasno current liability under the TRA.

As of December 31, 2023, the Company had derecognized the remaining $665.3 million non-current liability under the TRA after concluding it was not probable that the Company will be able to realize the remaining tax benefits based on estimates of future taxable income. As of December 31, 2024, the amount of the non-current liability amount that had been derecognized was $683.8 million. The estimation of liability under the TRA is by its nature imprecise and subject to significant assumptions regarding the amount, character, and timing of the taxable income in the future. If the Company concludes in a future period that the tax benefits are more likely than not to be realized and releases its valuation allowance, the corresponding TRA liability amounts may be considered probable at that time and recorded on the consolidated balance sheet and within earnings. There have been no changes to our position set forth in the 2024 Form 10-K. The impact of any activity for the year ending December 31, 2025, including any LLC Unit exchanges or changes to our estimated U.S. federal, state and local income tax rates, will be included in the Company’s Annual Report on Form 10-K for the year ending December 31, 2025 when amounts are determinable.

As of June 30, 2025 and December 31, 2024, there wereno liabilities outstanding under the TRA.

During the three and six months ended June 30, 2025 and 2024, no payments were made to MLSH 1 or MLSH 2 pursuant to the TRA.

Topco LLC Operating Agreement

MLSH 1 is party to the LLC Operating Agreement put in place at the date of the Organizational Transactions. This agreement includes a provision requiring cash distributions enabling its owners to pay their taxes on income passing through from Topco LLC. During each of the three and six months ended June 30, 2025, no such cash distributions were made for tax liabilities to MLSH 1 under this agreement. During each of the three and six months ended June 30, 2024, the Company made cash distributions of $0.6 million for tax liabilities to MLSH 1 under this agreement.

12. Segments

The Company’s financial performance is reported intwo segments. A description of each segment follows:

•Nucleic Acid Production: focuses on the manufacturing and sale of highly modified nucleic acids products to support the needs of customers’ research, therapeutic and vaccine programs. This segment also provides research products for labeling and detecting proteins in cells and tissue samples.

•Biologics Safety Testing: focuses on the manufacturing and sale of host cell protein, bioprocess impurity detection, viral clearance prediction kits and associated products. This segment also provides services for custom antibody development, assay development, antibody affinity extraction and mass spectrometry that are utilized by our customers in their biologic drug manufacturing spectrum.

The Company has determined that adjusted earnings before interest, tax, depreciation and amortization (“Adjusted EBITDA”) is the profit or loss measure that the CODM uses to make resource allocation decisions and evaluate segment performance. Adjusted EBITDA assists management in comparing the segment performance on a consistent basis for purposes of business decision-making by removing the impact of certain items that management believes do not directly reflect the Company’s core operations and, therefore, are not included in measuring segment performance. The Company defines Adjusted EBITDA as net loss before interest, taxes, depreciation and amortization, certain non-cash items and other adjustments that we do not consider in our evaluation of ongoing operating performance from period to period. Corporate costs, net of eliminations, are managed on a standalone basis and are not allocated to segments.

The following schedules include revenue, expenses, and Adjusted EBITDA for each of the Company’s reportable segments for the periods presented (in thousands):

(1)Expenses are adjusted to remove the impact of certain items that management believes do not directly reflect our core operations, and, therefore, are not included in measuring segment performance.

(2)Other segment items for each reportable segment include realized and unrealized (losses) gains on foreign exchange transactions.

(3)For both the three and six months ended June 30, 2025, stock-based compensation benefit of $3.3 million primarily related to forfeited stock awards in connection with the Executive Leadership Transition is included on the stock-based compensation line item.

(4)For the three months ended June 30, 2024, there was animmaterial amount of stock-based compensation expense in connection with the restructuring included in the stock based-compensation line item. For the six months ended June 30, 2024, stock-based compensation benefit of $1.2 million related to forfeited stock awards in connection with the restructuring is included on the stock-based compensation line item.

There wasno intersegment revenue during the three and six months ended June 30, 2025 and 2024.

The Company does not allocate assets to its reportable segments as they are not included in the review performed by the CODM for purposes of assessing segment performance and allocating resources.

13. Subsequent Event

On August 11, 2025, the Company announced a workforce reduction to reduce operating costs. The workforce reduction was committed to by management on August 8, 2025 and is expected to impact approximately 25% of the Company’s workforce. The Company currently estimates it will incur restructuring costs of approximately $8.0 million to $9.0 million, consisting primarily of employee severance, benefits, and related costs, the majority of which the Company expects to recognize in the second half of 2025.

The estimated expenses are subject to a number of assumptions and actual results may differ materially from the estimated amount. The Company may also incur additional costs not currently contemplated due to events that may occur as a result of, or in connection with, the workforce reduction.
