Schrodinger Inc

Notes to Consolidated Financial Statements

For the years ended December 31, 2023, 2022, and 2021

(in thousands, except for share and per share amounts and note 3(c))

(1)Description of Business

Schrödinger, Inc. (the “Company”) has developed a differentiated, physics-based computational platform that enables discovery of high-quality, novel molecules for drug development and materials applications more rapidly and at a lower cost, compared to traditional methods. The Company's software platform is licensed by biopharmaceutical and industrial companies, academic institutions, and government laboratories around the world. The Company is also applying its computational platform to advance a broad pipeline of drug discovery programs in collaboration with leading biopharmaceutical companies. In addition, the Company uses its computational platform to discover novel molecules for its pipeline of proprietary drug discovery programs, which the Company is advancing through preclinical and clinical development.

(2)Significant Accounting Policies

(a)Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2023-07, Segment Reporting (Topic 280) —Improvements to Reportable Segment Disclosures, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This standard is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted. The Company has not yet adopted ASU 2023-07 and is still evaluating the impact of the adoption on its consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) —Improvements to Income Tax Disclosures, which requires public business entities to disclose specific categories in the tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This standard is effective for annual periods beginning after December 15, 2024, and interim periods within annual periods beginning after December 15, 2025, on a prospective basis, with early adoption permitted. The Company has not yet adopted ASU 2023-09 and is still evaluating the impact of the adoption on its consolidated financial statements.

(b)Basis of Presentation and Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the assumptions used in the allocation of revenue and estimates regarding the progress of completing performance obligations under collaboration agreements. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.

(c)Principles of Consolidation

The Company’s consolidated financial statements include the accounts of Schrödinger, Inc., its wholly owned subsidiaries, and its variable interest entity. All intercompany balances and transactions have been eliminated in consolidation. The functional currency for foreign entities is the United States dollar. The Company accounts for investments over which it has significant influence, but not a controlling financial interest, using the equity method.

(d)Cash and Cash Equivalents and Marketable Securities and Restricted Cash

Included in cash and cash equivalents were cash equivalents of $85,497 and $78,066 as of December 31, 2023 and 2022, respectively, which consisted of money market funds and certificates of deposit, and are stated at cost, which approximates market value. The Company classifies all highly liquid investments with an original maturity of 90 days or less to be cash equivalents. The Company classifies all marketable securities, which consist of fixed income securities, as available for sale securities.

At times, cash balances held at financial institutions were in excess of the Federal Deposit Insurance Corporation’s insured limits; however, the Company primarily places its cash with high-credit quality financial institutions.

Restricted cash consists of letters of credit held with the Company’s financial institution related to facility leases and is classified as current in the Company’s balance sheets based on the maturity of the underlying letters of credit. Additionally, funds received from certain grants are restricted as to their use and are therefore classified as restricted cash.

(e)Accounts Receivable

Accounts receivable are stated at original invoice amount less an allowance for doubtful accounts. Management estimates the allowance for doubtful accounts by evaluating individual customer receivables and considering a customer’s financial condition, credit history, and current economic conditions. Account balances are considered delinquent if payment is not received by the due date. Accounts receivable are written off when deemed uncollectible. Recovery of accounts receivable previously written off is recorded when received. Changes in the balance of accounts deemed uncollectible were deemed immaterial as of December 31, 2023 and 2022. Interest is not charged on accounts receivable.

(f)Fair Value of Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short maturities.

(g)Property and Equipment

Property and equipment are stated at cost. The Company didnot capitalize any interest during 2023 and 2022. Maintenance and repairs are expensed as incurred.

Depreciation is calculated using the straight‑line method over the estimated useful lives of the assets, which range from 3 to 10 years. Amortization of leasehold improvements is calculated using the straight‑line method over the remaining life of the lease or the useful life of the asset, whichever is shorter.

Property and equipment are reviewed for impairment as discussed below under Accounting for the Impairment of Long‑Lived Assets.

(h)Goodwill

Goodwill represents the excess purchase price over the fair value of net assets acquired which is not allocable to separately identifiable intangible assets. Other identifiable intangible assets are separately recognized if the intangible asset is obtained through contractual or other legal right or if the intangible asset can be sold, transferred, licensed or exchanged.

Goodwill is not amortized but tested for impairment at least annually, and more frequently if events or circumstances indicate the carrying amount more likely than not exceeds the fair value. The Company has the option to qualitatively or quantitatively assess its goodwill for impairment.

The Company tests its goodwill for impairment on October 1 of each year. In 2023, the Company evaluated its goodwill using a qualitative process. If the qualitative factors determine that it is more likely than not that the fair value exceeds the carrying amount, goodwill is not impaired. If the qualitative assessment determines it is more likely than not the fair value is less than the carrying amount, the Company would further evaluate for potential impairment. The Company has deemed its goodwill not impaired for the year ended December 31, 2023.

(i)Accounting for the Impairment of Long‑Lived Assets

Long-lived assets, such as property and equipment and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for potential impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that carrying value exceeds fair value. Fair value is determined using various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, depending on the nature of the asset. No impairment was identified for the years ended December 31, 2023, 2022, and 2021.

(j)Warranties

The Company typically warrants that its products will perform in a manner consistent with the product specifications provided to the customer for a period of 30 days. Historically, the Company has not been required to make payments under these obligations. Therefore, no liabilities for such obligations are presented in the consolidated financial statements.

(k)Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade receivables and contract assets, which represent contracted unbilled receivables.

The Company does not require customers to provide collateral to support accounts receivable. If deemed necessary, credit reviews of significant new customers may be performed prior to extending credit. The determination of a customer’s ability to pay requires judgment, and failure to collect from a customer can adversely affect revenue, cash flows, and results of operations.

As of December 31, 2023, two customers accounted for 15% and 11% of total accounts receivable, respectively. As of December 31, 2022, one customer accounted for 26% of total accounts receivable. As of December 31, 2023, two customers accounted for 42% and 22% of total contract assets, respectively. As of December 31, 2022, two customers accounted for 23% and 17% of total contract assets, respectively. For the year ended December 31, 2023, two customers accounted for 26% and 11% of total revenues, respectively. For the year ended December 31, 2022, one customer accounted for 16% of total revenues. For the year ended December 31, 2021, one customer accounted for more than 14% of total revenues.

(l)Royalties

Royalties represent a component of cost of revenues and consist of royalties paid to owners of intellectual property used in or bundled with the Company’s software. Generally, royalties are incurred and recorded at the time a customer enters into a binding purchase agreement, although some royalty agreements are based instead on cash collections. Royalty expense was $13,349, $9,191, and 9,826 for the years ended December 31, 2023, 2022, and 2021, respectively.

(m)Software Development Costs

Costs to develop new software products and substantial enhancements to existing software products are expensed as incurred. Historically, the Company has not capitalized any software development costs because the software development process was essentially completed concurrent with the establishment of technological feasibility.

(n)Research and Development and Advertising

Research and development and advertising costs are expensed as incurred. The Company did not incur any significant advertising costs in 2023, 2022, and 2021.

(o)Stock‑Based Compensation

The Company calculates stock‑based compensation expense utilizing fair value–based methodologies and recognizes expense over the vesting period of such awards. For performance-based restricted stock units, the Company records stock-based compensation expense with a cumulative catch-up at the time when performance conditions are considered probable of achievement, and on a straight-line basis over the remaining period for which the performance criteria are expected to be completed.

(p)Commissions

Commissions represent a component of sales and marketing expense and consist of the variable compensation paid to the Company’s sales representatives. Generally, sales commissions are earned and recorded as expense at the time that a customer has entered into a binding purchase agreement. Commissions paid to sales representatives are recoverable only in the case that the Company cannot collect against any invoiced fee associated with a sales order. Commission expense was $1,636, $2,291, and $1,829 in 2023, 2022, and 2021, respectively.

(q)Income Taxes

The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of the assets and liabilities. Deferred tax assets are reduced by a valuation allowance when it is estimated to become more likely than not that a portion of the deferred tax assets will not be realized. Accordingly, the Company currently maintains a full valuation allowance against existing net deferred tax assets.

The Company recognizes the effect of income tax positions only if such positions are deemed “more likely than not” capable of being sustained. Interest and penalties accrued on unrecognized tax benefits are included within income tax expense in the consolidated financial statements.

(r)Comprehensive Income (Loss)

Comprehensive income (loss) includes net income (loss) and changes in equity related to changes in unrealized gains or losses on marketable securities.

(s)Equity Investments

In the normal course of business, the Company has entered, and may continue to enter, into collaboration agreements with companies to perform drug design services for such companies in exchange for equity ownership stakes in such companies. If it is determined that the Company has control over the investee, the investee is consolidated in the financial statements. If the investee is consolidated with the Company and less than 100% of the equity is owned by the Company, the Company will present non-controlling interest to represent the portion of the investee owned by other investors. If it is determined that the Company does not have control over the investee, the Company evaluates the investment for the ability to exercise significant influence.

Equity investments over which the Company has significant influence may be accounted for under equity method accountingin accordance with Accounting Standards Codification ("ASC") Topic 323, Equity Method and Joint Ventures. If it is determined that the Company does not have significant influence over the investee, and there is no readily determinable fair value for the investment, the equity investment may be accounted for at cost less impairment, in accordance with ASC Topic 321 ("Topic 321"), Equity Securities.

For further information regarding the Company’s equity investments, see Note 6, Fair Value Measurements and Note 13, Equity Investments.

(t)Net Income (Loss) per Share Attributable to Common and Limited Common Stockholders

The outstanding equity of the Company consists of common stock and limited common stock. Under the Company’s certificate of incorporation, the rights of the holders of common stock and limited common stock are identical, except with respect to voting and conversion. Holders of limited common stock are precluded from voting such shares in any election of directors or on the removal of directors. Limited common stock may be converted into common stock at any time at the option of the stockholder.

Undistributed earnings allocated to the participating securities are subtracted from net income in determining net income (loss) attributable to common and limited common stockholders. Basic net income (loss) per share is computed by dividing net income (loss) attributable to common and limited common stockholders by the weighted-average number of shares of common and limited common stock outstanding during the period.

For the calculation of diluted net income, net income attributable to common and limited common stockholders for basic net income is adjusted by the effect of dilutive securities, including awards under the Company’s equity compensation plans. Diluted net income per share attributable to common and limited common stockholders is computed by dividing the resulting net income attributable to common and limited common stockholders by the weighted-average number of fully diluted shares of common and limited common stock outstanding.

(3)Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time or at a point in time, which can result in different revenue recognition patterns.

The following table illustrates the timing of the Company’s revenue recognition patterns:

(a) Software Products and Services

The Company enters into contracts that can include various combinations of licenses, products and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation on a relative standalone selling price (“SSP”) basis. Revenue is recognized net of any sale and value-added taxes collected from customers and subsequently remitted to governmental authorities.

The Company’s software business derives revenue from five sources: (i) on-premise software license fees, (ii) hosted software subscription fees, (iii) software maintenance fees, (iv) professional services fees, and (v) contributions.

On-premise software. The Company’s on-premise software license arrangements grant customers the right to use its software on their own in-house servers or their own cloud instances for a specified term, typically forone year, though in recent years, the Company has entered into a small number of large multi-year on-premise software license agreements. The Company recognizes revenue for on-premise software license fees upfront, either upon transfer of control of the license or the effective date of the agreement, whichever is later. In instances where the timing of delivery differs from the timing of invoicing, the Company considers whether a significant financing component exists. The Company has elected the practical expedient to not assess for significant financing where the term is less than one year. The Company’s updates and upgrades are not integral to maintaining the utility of the software licenses. Payments typically are received upfront or annually.

Hosted software. Hosted software revenue consists primarily of fees to provide the Company’s customers with hosted licenses, which allows these customers to access the Company's cloud-based software solution on their own hardware without taking control of the licenses, and is recognized ratably over the term of the arrangement, which is typically one year, though in recent years, the Company has entered into a small number of large multi-year hosted software license agreements. When a customer enters into a hosted arrangement for which revenue is recognized over time, the amount paid upfront that is not recognized in the current period is included in deferred revenue in the Company's statement of financial position until the period in which it is recognized.

Software maintenance. Software maintenance includes technical support, updates, and upgrades related to the Company's on-premise software licenses. Software maintenance revenue is recognized ratably over the term of the arrangement. Software maintenance activities are performed in connection with the use of the Company's on-premise software, and may fluctuate from period to period.

Professional services. Professional services include training, technical setup, installation or assisting customers with modeling services, where the Company uses its software to perform tasks such as virtual screening on behalf of the Company’s customers. These services are generally not related to the core functionality of the Company’s software and are recognized as revenue when resources are consumed. Since each professional services agreement represents a unique, ad hoc engagement, professional services revenue may fluctuate from period to period.

Software contribution revenue. Software contribution revenue consists of funds received under a non-reciprocal agreement with Gates Ventures, LLCoriginally entered into in June 2020 and further extended through August 2026. The agreement is an unconditional non-exchange contribution without restrictions. Revenue was recognized annually from June 2020 through June 2022 and upon extension of the agreement in August 2023, when invoiced, in accordance with ASC Topic 958, Not-for-Profit Entities as the agreement is not an exchange transaction.

The agreement with Gates Ventures, LLC initially covered the period from June 23, 2020 through June 22, 2023 for total consideration of up to $3,000. The Company recognized revenue of $1,000 upon entry into the agreement and $1,000 upon each of the first and second anniversary of the agreement. During the period ended September 30, 2023, the agreement was extended through August 13, 2026 and provides for total additional consideration of up to $6,000. The Company recognized revenue of $1,800 upon extension of the agreement. As of December 31, 2023, the Company hadno deferred revenue balance related to this agreement. As of December 31, 2023 and 2022, the Company hadno accounts receivable related to this agreement.

The following table presents the revenue recognized from the sources of software products and services revenue:

(b) Drug Discovery

Drug discovery services. Revenue from drug discovery and collaboration services contracts is recognized either over time or at a point in time, typically by using costs incurred, hours expended to measure progress, or based on the achievement of milestones. Payments for services are generally due upfront at the start of a contract, upon achieving milestones stated in a contract, or upon consumption of resources. Services may at times include variable consideration, and the Company has estimated the amount of consideration that is variable using the most likely amount method. The Company evaluates milestones on a case-by-case basis, including whether there are factors outside the Company’s control that could result in a significant reversal of revenue, and the likelihood and magnitude of a potential reversal. If achievement of a milestone is not considered probable, the Company constrains (reduces) variable consideration to exclude the milestone payment until it is probable to be achieved. Upon removal of the constraint on variable consideration, revenue may be recognized at a point in time or over time by applying the allocation guidance of ASC Topic 606, Revenue from Contracts with Customers ("Topic 606").

As of December 31, 2023, 2022, and 2021, milestones not yet achieved that were determined to be probable of achievement totaled $350, $4,000, and $2,250, respectively, and $350, $3,939, and $2,250 of those milestones were recognized as revenue for the years ended December 31, 2023, 2022, and 2021, respectively.

Drug discovery contribution revenue. Drug discovery contribution revenue consists of funds received under an agreement with the Bill and Melinda Gates Foundation on a cost reimbursement basis, to perform services aimed at accelerating drug discovery in women’s health. The initial agreement began in November 2021 and expired in September 2023. In September 2023, the Company entered into a new agreement with the Bill and Melinda Gates Foundation to perform services aimed at accelerating drug discovery in women's health that expires in October 2025. Revenue is recognized as conditions are met in accordance with ASC Topic 958, Not-for-Profit Entities. As of December 31, 2023 and 2022, the Company had deferred revenue balances related to these agreements of $1,581 and $1,718, respectively.

The following table presents the revenue recognized from the sources of drug discovery revenue:

(c) Collaboration and License Agreement

On November 22, 2020, the Company entered into an exclusive, worldwide collaboration and license agreement with Bristol-Myers Squibb Company (“BMS”), pursuant to which the Company and BMS have agreed to collaborate in the discovery, research and preclinical development of new small molecule compounds for disease indications in oncology, neurology, and immunology therapeutics areas. Under the agreement, the Company was initially responsible, at its own cost and expense, for the discovery of small molecule compounds directed tofive specified biological targets pursuant to a mutually agreed research plan for each such target. The initial targets included HIF-2 alpha and SOS1/KRAS, which weretwo of the Company’s proprietary programs. In November 2021, the Company and BMS mutually agreed to replace the HIF-2 alpha target with another precision oncology target. Following the replacement election, all rights to the HIF-2 alpha target program reverted to the Company. In September 2022, BMS elected not to proceed with further development of another target and all rights to this program reverted to the Company, which increased revenue recognition in the third quarter of 2022 due to the accelerated completion of the Company's obligations related to the program. In December 2022, the Company and BMS entered into an amendment to the agreement to include an additional target in neurology on terms similar to the original agreement. In September 2023, BMS elected not to proceed with further development oftwo related oncology programs and all rights to these programs reverted to the Company, which increased revenue recognition in the third quarter of 2023 due to the accelerated completion of the Company's obligations related to those programs.

Once a development candidate meeting specified criteria for a target under the agreement has been identified by the Company, BMS will be solely responsible for the further development, manufacturing and commercialization of such development candidate at its own cost and expense.

Under the terms of the agreement, as amended, BMS paid the Company an initial upfront fee payment of $55.0 million in November 2020 and an additional upfront payment in December 2022. The Company also is eligible to receive up to $1.5 billion in total milestone payments across the potential currently targets subject to the collaboration, consisting of: a) up to $585.0 million in milestone payments per oncology target, consisting of $360.0 million in the aggregate for the achievement of certain specified research, development, and regulatory milestones and $225.0 million in the aggregate for the achievement of certain specified commercial milestones; and b) up to $489.0 million in milestone payments per neurology and immunology target, consisting of $264.0 million in the aggregate for the achievement of certain specified research, development, and regulatory milestones and $225.0 million in the aggregate for the achievement of certain specified commercial milestones. As of December 31, 2023, the Company has recognized $25.0 million in revenue related to milestones under this agreement.

The Company is also entitled to a tiered percentage royalty on annual net sales ranging from mid-single digits to low-double digits, subject to certain specified reductions. Royalties are payable by BMS on a licensed product-by-licensed product and country-by-country basis until the later of the expiration of the last valid claim covering the licensed product in such country, expiration of all applicable regulatory exclusivities in such country for such licensed product and the tenth anniversary of the first commercial sale of such licensed product in such country.

The Company assessed the collaboration and license agreement in accordance with Topic 606, and concluded that BMS is a customer based on the agreement structure. At inception, the Company identifiedone performance obligation for each of thefive programs initially covered under the agreement, which includes research activities for each program and a license grant for the underlying intellectual property. The Company determined that the license grant for intellectual property is not separable from the research activities, as the research activities are expected to significantly modify or enhance the license grant over the period of service, and therefore are not distinct in the context of the contract.

The Company determined that the transaction price at the onset of the agreement is $55.0 million. Additional consideration to be paid to the Company upon the achievement of future milestone payments were excluded from the transaction price as they represent milestone payments that are not considered probable as of the inception date such that there is not a significant risk of revenue reversal.

The Company has allocated the transaction price of $55.0 million to each performance obligation based on the SSP of each performance obligation at inception, which was determined based on each performance obligation’s estimated SSP. The Company determined the estimated SSP at contract inception of the research activities based on internal estimates of the costs to perform the services, inclusive of a reasonable profit margin. Significant inputs used to determine the total costs to perform the research activities included the length of time required, the internal hours expected to be incurred on the services and the number and costs of various studies that will be performed to complete the research plan.

Revenue associated with the research activities is recognized on a proportional performance basis over the period of service for research activities, using input-based measurements of total costs of research incurred to estimate the proportion performed. Progress towards completion is remeasured at the end of each reporting period.

During the years ended December 31, 2023, 2022, and 2021, the Company recognized $43.2 million, $22.1 million, and $13.7 million of revenue, respectively, associated with the agreement based on the research activities performed and milestones achieved. As of December 31, 2023 and 2022, there was $7.3 million and $25.5 million of deferred revenue related to the agreement, which was classified as either current or non-current in the consolidated balance sheet based on the period the services are expected to be performed. There wereno outstanding receivables for this collaboration as of December 31, 2023.

(d) Significant Judgments

Significant judgments and estimates are required under Topic 606. Due to the complexity of certain contracts, the actual revenue recognition treatment required under Topic 606 for the Company’s arrangements may be dependent on contract-specific terms and may vary in some instances.

The Company’s contracts with customers often include promises to transfer multiple software products and services, including training, professional services, technical support services, and rights to unspecified updates. Determining whether licenses and services are distinct performance obligations that should be accounted for separately, or are not distinct and therefore should be accounted for together, requires significant judgment. In some arrangements, such as most of the Company’s term-based software license arrangements, the Company has concluded that the licenses and associated services are distinct from each other. In other arrangements, including collaboration services arrangements, the licenses and certain services may not be distinct from each other. The Company’s time-based software arrangements may include multiple software licenses and a right to updates or upgrades to the licensed software products, and technical support. The Company has concluded that such promised goods and services are separate distinct performance obligations.

The Company is required to estimate the total consideration expected to be received from contracts with customers, including any variable consideration. For collaborative arrangements, under which the Company is eligible to receive variable consideration in the form of milestones payments, judgment is required to evaluate whether the milestones are considered probable of being achieved. If it is probable that a significant revenue reversal would not occur, the constraint is removed and value of the associated milestone is included in the estimated transaction price using the most likely amount method based on contractual requirements and historical experience. Once the estimated transaction price is established, amounts are allocated to the performance obligations that have been identified. The transaction price is allocated to each separate performance obligation on a relative SSP basis consistent with the allocation objectives of Topic 606.

Judgment is required to determine the SSP for each distinct performance obligation. The Company rarely licenses or sells products on a standalone basis, so the Company is required to estimate the range of SSPs for each performance obligation. In instances where the SSP is not directly observable because the Company does not sell the license, product, or service separately, the Company determines the SSP using information that includes historical discounting practices, market conditions, cost-plus analysis, and other observable inputs. The Company typically has more than one SSP for individual performance obligations due to the stratification of those items by volume of sales, classes of customers and other relevant circumstances. In these instances, the Company may use information such as the size and geographic region of the customer in determining the SSP. Professional service revenue is recognized as costs and hours are incurred, and judgment is required in estimating both the project status and the costs incurred or hours expended.

If a group of agreements are so closely related to each other that they are, in effect, part of a single arrangement, such agreements are deemed to be one arrangement for revenue recognition purposes. The Company exercises significant judgment to evaluate the relevant facts and circumstances in determining whether the separate agreements should be accounted for separately or as, in substance, a single arrangement. The Company’s judgments about whether a group of contracts comprises a single arrangement can affect the allocation of consideration to the distinct performance obligations, which could have an effect on results of operations for the periods involved.

Judgment is required to determine the total costs to perform research activities, which include the length of time required, the internal hours expected to be incurred on the services, and the number and costs of various studies that may be performed by third-parties to complete the research plan.

Generally, the Company has not experienced significant returns or refunds to customers.

The Company’s estimates related to revenue recognition may require significant judgment and a change in these estimates could have an effect on the Company’s results of operations during the periods involved.

(e) Contract Balances

The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in receivables, contract assets, or contract liabilities (deferred revenue) on the consolidated balance sheets. The Company records a contract asset when revenue is recognized prior to invoicing. A deferred revenue liability is recorded when revenue is expected to be recognized subsequent to invoicing. For the Company’s time-based software agreements, customers are generally invoiced at the beginning of the arrangement for the entire term, though when the term spans multiple years the customers may be invoiced on an annual basis. For certain drug discovery agreements where the milestones are deemed probable in a period prior to when the milestone is achieved, the Company records a contract asset for the full value of the milestone.

Contract assets are included in unbilled and other receivables within the consolidated balance sheets and are transferred to receivables when the Company invoices the customer.

Contract balances were as follows:

For the years ended December 31, 2023 and 2022, the Company recognized $64,120 and $60,039 of revenue, respectively, that was included in deferred revenue at the end of the respective preceding periods. All other deferred revenue activity is due to the timing of invoices in relation to the timing of revenue, as described above. The Company expects to recognize as revenue approximately 86% of its December 31, 2023 deferred revenue balance in the next 12 months and the remainder thereafter. Additionally, contracted but unsatisfied performance obligations that had not yet been billed to the customer or included in deferred revenue were $36,357 as of December 31, 2023.

Payment terms and conditions vary by contract type, although terms typically require payment within 30 to 60 days. In instances where the timing of revenue recognition differs from that of invoicing, the Company has determined that its contracts generally do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to facilitate financing arrangements.

(f) Deferred Sales Commissions

The Company has applied the practical expedient for sales commission expense, as any material compensation paid to sales representatives to obtain a contract relates to a period of one year or less. The Company has not capitalized any costs related to sales commissions.

(4)Property and Equipment

Property and equipment consisted of the following:

Depreciation expense for 2023, 2022, and 2021 was $4,965, $3,831, and $2,847, respectively, and is included within cost of revenues and research and development, sales and marketing, and general and administrative expenses within the consolidated statements of operations.

(5)Business Acquisition

On January 14, 2022, the Company used cash on hand to acquire all outstanding shares of XTAL BioStructures, Inc. (“XTAL”), a company that provides structural biology services, including biophysical methods, protein production and purification, and X-ray crystallography. The transaction qualified as a business combination for accounting purposes, which involves application of the acquisition method described in ASC 805, Business Combinations("Topic 805"). The cash purchase price was approximately $7,429 which included $6,427 in upfront purchase price, net of cash acquired. The acquisition of XTAL enables the Company to pursue scientific advancements in the field of structural biology, augment its ability to produce high quality target structures for its proprietary drug discovery programs, and expand its offerings to include an advanced and differentiated service that provides customers access to protein structures that have been computationally validated and are ready for structure-based virtual screening and lead optimization, giving rise to expected benefits supporting the amount of acquired goodwill.

The following table summarizes the fair values of the assets acquired and liabilities assumed by the Company as of the January 14, 2022 acquisition date. The business combination accounting under Topic 805 was finalized for this acquisition during the three months ended June 30, 2022, with no changes to the provisional amounts disclosed for the three months ended March 31, 2022. The Company elected to use both practical expedients provided by ASU No. 2021-08 for the valuation of contract assets and contract liabilities from contracts with customers, with no material impact to the consolidated financial statements.

The following table summarizes the purchase price allocation to the identifiable intangible assets and their estimated useful lives as of the January 14, 2022 acquisition date. All intangibles have been fully amortized as of December 31, 2023:

The results of operations for XTAL beginning as of the January 14, 2022 acquisition date are included in these consolidated financial statements. For the fiscal year ended December 31, 2022, the amount of revenues and net income of XTAL were not material to the consolidated financial statements taken as a whole. Because the pro forma results of operations of the Company for the periods presented in these consolidated financial statements would not be materially different as a result of the acquisition, such information is not presented. The costs incurred to acquire XTAL were not material and have been fully expensed and are included in general and administrative expenses in the consolidated statements of operations. Amortization of intangibles was $587 and $513 in general and administrative expenses as of December 31, 2023 and 2022, respectively.

(6)Fair Value Measurements

Various inputs are used in determining the fair value of the Company’s financial assets and liabilities. These inputs are summarized into the following three broad categories:

Level 1 – quoted prices in active markets for identical securities

Level 2 – other significant observable inputs, including quoted prices for similar securities, interest rates, credit risk, etc.

Level 3 – significant unobservable inputs, including the Company’s own assumptions in determining fair value

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Marketable securities, which consist primarily of corporate and U.S. government agency bonds, are classified as available for sale and fair value did not differ significantly from carrying value as of December 31, 2023 and 2022. The following table presents information about the Company’s assets measured at fair value as of December 31, 2023:

The following table presents information about the Company’s assets measured at fair value as of December 31, 2022:

The following table sets forth changes in fair value of the Company’s Level 3 investments:

The fair value of the Company’s investment in Nimbus Therapeutics, LLC (“Nimbus”), classified as Level 3 in the fair value hierarchy, was recorded as an equity method investment under ASC Topic 323, Investments - Equity Method and Joint Ventures, using the hypothetical liquidated book value method (“HLBV method”) through June 30, 2023, as further described in Note 13, Equity Investments. Significant unobservable inputs used to determine Nimbus’ fair value under the HLBV method were the entity's annual financial statements and the Company’s liquidation preference. During the year ended December 31, 2023, the Company recorded a gain of $147,213 on account of its equity position in Nimbus following the closing of Takeda's acquisition of Nimbus Lakshmi, Inc., a wholly-owned subsidiary of Nimbus, and its tyrosine kinase 2 inhibitor, NDI-034858. On February 13, 2023, the Company reported receipt of a $111,328 cash distribution from Nimbus related to the sale. On April 6, 2023, the Company reported receipt of a $35,789 cash distribution from Nimbus related to the sale. On November 9, 2023, the Company reported receipt of a $96 cash distribution from Nimbus related to the sale. The realized gain on Level 3 investment during the year ended December 31, 2023 relates to these cash distributions from Nimbus. Following the dilution of the Company's investment in Nimbus during the three months ended September 30, 2023, the fair value of the Company's investment is recorded under ASC Topic 321 as a non-marketable equity security as the Company no longer exercises significant influence over Nimbus. This change in accounting method resulted in an unrealized gain of $1,928.

During the three months ended March 31, 2023, the Company recorded a transfer of $1,629 from a Level 3 investment to a Level 1 investment due to the completion of Structure Therapeutics Inc.'s, ("Structure Therapeutics"), initial public offering ("IPO"). The Company's investment in Structure Therapeutics was previously recorded using the HLBV method. Following the completion of Structure Therapeutics' IPO, the Company's investment in Structure Therapeutics is recorded under Topic 321 because there is an observable price of the investment. During the year ended December 31, 2022 there were no transfers between Level 1, Level 2 and Level 3 investments.

Unrealized gains and losses arising from changes in fair value of the Company’s equity investments are classified within change in fair value in the consolidated statements of operations. Realized gains arising from distributions receivable from the Company's equity investments are classified within gain on equity investments in the consolidated statements of operations.

For further information regarding the Company’s equity investments, see Note 13, Equity Investments.

(7)Commitments and Contingencies

(a) Leases

The Company has multiple operating leases for office space and a finance lease for equipment that expire at various dates through 2037. The Company has elected the package of practical expedients under the transition guidance of ASC Topic 842, Leases, to exclude short-term leases from the balance sheet and to combine lease and non-lease components. The Company classifies finance lease right of use assets under property and equipment, net and finance short-term and long-term lease liabilities under other accrued liabilities and other liabilities, long-term, respectively.

Upon inception of a lease, the Company determines if an arrangement is a lease, if it is classified as an operating or finance lease, if it includes options to extend or terminate the lease, and if it is reasonably certain that the Company will exercise the options. Lease cost, representing lease payments over the term of the lease and any capitalizable direct costs less any incentives received, is recognized on a straight-line basis over the lease term as lease expense.

In determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date if the rate implicit in the lease is not readily determinable. Upon execution of a new lease, the Company performs an analysis to determine its incremental borrowing rate using its current borrowing rate, adjusted for various factors including level of collateralization and lease term. As of December 31, 2023, the remaining weighted average lease term for operating and finance leases was 12 years.

During the year ended December 31, 2023, operating lease right of use (“ROU”) assets increased by $15,173 due to the accounting commencement offive new leases and by $4,388 due to contingency resolutions associated with office leases. During the same period, operating lease liabilities increased by $15,085 due the accounting commencement of the new leases. During the year ended December 31, 2023, finance lease right of use assets increased by $579 and finance lease liabilities increased by $279 due to the accounting commencement of an equipment lease for the Company's Framingham, Massachusetts lab.

Variable and short-term lease costs for the Company's operating and finance leases were immaterial for the year ended December 31, 2023. Additional details of the Company’s operating and finance leases are presented in the following table:

Maturities of operating and finance lease liabilities as of December 31, 2023 under noncancelable operating leases were as follows:

(b) Legal Matters

From time to time, the Company may become involved in routine litigation arising in the ordinary course of business. While the results of such litigation cannot be predicted with certainty, management believes that the final outcome of such matters is not likely to have a material adverse effect on the Company’s financial position or results of operations or cash flows.

(c) Contingencies

The Company is currently under audit with a royalty partner. As of December 31, 2023, the Company believes a contingency is probable and has accrued $2,500 related to this audit.

(8)Income Taxes

Income tax expense is comprised of the following:

Components of income (loss) before income taxes by tax jurisdiction were as follows:

Reconciliation of income tax expense at the applicable statutory income tax rates to the effective income tax rate is as follows:

Income tax expense for the year ended December 31, 2023 represents our federal and certain state income tax obligations and taxes in foreign jurisdictions for which we conduct business. Income tax expense for the years ended December 31, 2022 and 2021 represents our income tax obligations in certain states and taxes in foreign jurisdictions in which we conduct business. As of December 31, 2023, the Company has a full valuation allowance on U.S. federal and state deferred tax assets.

The total change in valuation allowance for the year ended December 31, 2023 was $1,926, which was primarily due to temporary differences for capitalized research and development expenses and share based compensation, partially offset by adjustments to equity method investments.

Tax effects of temporary differences that give rise to significant portions of deferred income tax assets and deferred income tax liabilities were as follows:

As of December 31, 2023, the Company had federal and state net operating loss (“NOL”) carryforwards of $179,076 and $98,576, respectively. The state NOL carryforwards will expire between 2025 and 2042, if not utilized. The federal NOL carryforwards are limited to 80% of taxable income generated in a given year and carry forward indefinitely. As of December 31, 2023, the Company had federal and state research and development tax credit carryforwards of $23,336 and $1,598, respectively. These carryforwards will expire between 2024 and 2043 if not utilized.

Pursuant to Internal Revenue Code Sections 382 and 383, the utilization of NOLs and other tax attributes may be substantially limited due to cumulative changes in ownership greater than 50% that may have occurred or could occur during applicable testing periods. The Company has performed an analysis through December 31, 2023 and determined that such an ownership change occurred on March 31, 2021. There was no material impact to the financial statements due to this ownership change.

The Company has not recognized a deferred tax liability for the undistributed earnings of its foreign operations as the Company considers these earnings to be indefinitely reinvested.

The Company classifies interest and penalties related to unrecognized tax benefits within income tax expense in the consolidated statement of operations. Following is a reconciliation of total gross unrecognized tax benefits:

The Company does not anticipate any significant increases or decreases in its uncertain tax positions within the next 12 months.

The Company and its subsidiaries file U.S. federal income tax returns and various state, local and foreign income tax returns. As of December 31, 2023, the Company’s statutes of limitations are open for all federal and state years tax returns filed after the years ended December 31, 2020 and 2019, respectively. NOL and credit carryforwards for all years are subject to examination and adjustments for the three years following the year in which the carryforwards are utilized. The Company is not currently under Internal Revenue Service or state examination.

As of December 31, 2023, the Company’s stock incentive plans included the 2010 Stock Plan (the “2010 Plan”), the 2020 Equity Incentive Plan (the “2020 Plan”), the 2021 Inducement Equity Incentive Plan, as amended (the “2021 Plan”), and the 2022 Equity Incentive Plan (the “2022 Plan”) (together, the “Plans”).

The 2022 Plan provides for the award of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units, other stock-based awards, and cash-based awards to employees, directors, consultants or advisors. Shares of common stock subject to outstanding awards granted under the 2020 Plan and the 2010 Plan that expire, terminate, or are otherwise surrendered, cancelled, forfeited, or repurchased by the Company are available for issuance under the 2022 Plan.

The 2021 Plan provides for the award of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units, and other stock-based awards to persons who were not previously an employee or director of the Company or who are commencing employment with the Company following a bona fide period of non-employment, in either case, as an inducement material to such person’s entry into employment with the Company and in accordance with the requirements of the Nasdaq Stock Market Rule 5635(c)(4).

As of December 31, 2023, there were 3,472,195 shares available for grant under the Plans. The following table presents classification of stock-based compensation expense within the consolidated statements of operations:

Restricted Stock Units

Each restricted stock unit (“RSU”) represents the right to receive one share of the Company’s common stock upon vesting. The fair value of RSUs granted by the Company was calculated based upon the Company’s closing stock price on the date of the grant, and the stock-based compensation expense is recognized over the vesting period. RSUs generally vest over four years with 25% of the grants vesting at the end of the first year and the remaining vesting annually over the following three years.

Restricted stock unit activity was as follows:

The weighted average grant date fair value for each RSU granted during the years ended December 31, 2023 and 2022 was $26.09 and $26.86, respectively.

As of December 31, 2023, there was $15,375 of unrecognized compensation cost related to RSUs granted under the Plans, which is expected to be recognized over a weighted average period of 3 years. During the year ended December 31, 2023,13,241 RSUs vested. The fair value of RSUs vested during the year ended December 31, 2023 was $355. No RSUs vested during year ended December 31, 2022.

Performance-Based Restricted Stock Units

In February 2023, the Company awarded performance-based restricted stock units ("PRSUs") under the 2022 Plan. Each PRSU represents a contingent right to receive one share of common stock upon the achievement of specified performance goals. The fair value of PRSUs granted by the Company was calculated based upon the Company's closing stock price on the date of the grant, and the stock-based compensation expense is recognized when the grant date is determined and performance conditions are probable of achievement.

In February 2023, the Company awarded to certain executive officers PRSUs for a maximum of 62,693 shares (based on 150% achievement of the applicable performance conditions outlined in the awards), with a target award of 41,795 PRSUs (based on 100% achievement of the applicable performance conditions), and a threshold award of 20,898 PRSUs (based on 50% achievement of the applicable performance conditions). All PRSUs were considered granted under ASC 718, Compensation—Stock Compensation("Topic 718") in February 2023. The PRSUs granted in February 2023 are scheduled to vest, if at all, upon the certification by the Company's compensation committee of the achievement of the applicable performance conditions following the filing of the Company's Annual Report on Form 10-K for the fiscal year ending December 31, 2025.

In August 2022, the Company awarded 90,000 PRSUs to an executive officer of which 30,150 PRSUs were considered granted under Topic 718 at the time the PRSUs were awarded. In March 2023, of the 90,000 PRSUs awarded in August 2022, an additional 45,000 PRSUs were considered granted under Topic 718. Of the 45,000 PRSUs that were considered granted in March 2023,18,000 PRSUs are scheduled to vest, if at all, upon the certification by the Company's compensation committee of the achievement of the applicable performance conditions following the filing of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and 27,000 PRSUs are scheduled to vest, if at all, upon the certification by the Company's compensation committee of the achievement of the applicable performance conditions following the filing of the Company's Annual Report on Form 10-K for the fiscal year ending December 31, 2025.

Performance based restricted stock unit activity was as follows:

The weighted average grant date fair value for each PRSU granted during the years ended December 31, 2023 and 2022 was $22.48 and $28.55, respectively. No PRSUs vested during the years ended December 31, 2023 and 2022.

Stock Options

Stock options must be granted at an exercise price not less than 100% of the fair market value per share at the grant date. The board of directors or compensation committee determines the exercise price of the Company’s stock options based on the closing price of the common stock as reported on the Nasdaq Global Select Market on the date of the grant. The maximum contractual term of options granted under the Plans is typically 10 years, options generally vest over four years with 25% of the shares underlying the option vesting at the end of the first year and the remaining vesting monthly over the following three years. In February 2023, the Company granted the chief executive officer a premium priced option to purchase 65,525 shares of common stock with an exercise price equal to 110% of the closing price of the Company's common stock on the date of grant.

During the years ended December 31, 2023, 2022, and 2021,800,336,329,224, and 1,120,981 options under the Plans were exercised for total proceeds of $9,440, $2,110, and $7,927, respectively.

The fair value of each option award is determined on the date of grant using the Black Scholes Merton option-pricing model. The calculation of fair value includes several assumptions that require management’s judgment. The expected terms of options granted to employees during the years ended December 31, 2023, 2022, and 2021 were calculated using an average of historical exercises. Estimated volatility for 2023, 2022, and 2021 incorporates a calculated volatility derived from the historical closing prices of shares of common stock of similar entities whose share prices were publicly available for the expected term of the option. The risk-free interest rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option. The Company accounts for forfeitures as they occur; as such, the Company does not estimate forfeitures at the time of grant.

Following are the weighted average valuation assumptions used for option awards during the periods presented:

Stock option activity was as follows:

The weighted average grant date fair value per share of options granted during the years ended December 31, 2023, 2022, and 2021 was $15.79, $13.67, and $45.07, respectively. The intrinsic value of options exercised during the years ended December 31, 2023, 2022, and 2021 was $16,213, $6,548, and $71,308, respectively.

As of December 31, 2023, there was $62,992 of unrecognized compensation cost related to unvested stock options granted under the Plans, which is expected to be recognized over a weighted average period of 2.10 years. The fair value of shares vested during the years ended December 31, 2023, 2022, and 2021 was $46,877, $43,559, and $19,080, respectively.

(11)Noncontrolling Interest

The Company reviews each legal entity formed by parties related to the Company to determine whether or not the Company has a variable interest in the entity and whether or not the entity would meet the definition of a variable interest entity (“VIE”) in accordance with ASC Topic 810, Consolidation. If the entity is a VIE, the Company assesses whether or not the Company is the primary beneficiary of that VIE based on a number of factors, including (i) which party has the power to direct the activities that most significantly affect the VIE’s economic performance, (ii) the parties’ contractual rights and responsibilities pursuant to any contractual agreements and (iii) which party has the obligation to absorb losses or the right to receive benefits from the VIE. If the Company determines it is the primary beneficiary of a VIE, the Company consolidates the financial statements of the VIE into the Company’s consolidated financial statements at the time that determination is made. The Company evaluates whether it continues to be the primary beneficiary of any consolidated VIEs on a quarterly basis. If the Company were to determine that it is no longer the primary beneficiary of a consolidated VIE, or no longer has a variable interest in the VIE, it would deconsolidate the VIE in the period that the determination is made.

If the Company determines it is the primary beneficiary of a VIE that meets the definition of a business, the Company measures the assets, liabilities and noncontrolling interests of the newly consolidated entity at fair value in accordance with Topic 805 at the date the reporting entity first becomes the primary beneficiary.

In October 2018, Faxian Therapeutics, LLC (“Faxian”) was formed in the United States. In April 2019, upon consummation of the joint venture, the Company and WuXi AppTech ("WuXi"), each received a 50% equity interest in the entity in exchange for their contributions to the entity. The Company determined that Faxian was a VIE and concluded that it is the primary beneficiary of the VIE. As such, the Company has consolidated Faxian's results into the consolidated financial statements, and eliminated WuXi's ownership as a non-controlling interest.

(12)Net Income (Loss) per Share Attributable to Common and Limited Common Stockholders

The following table presents the calculation of basic and diluted net income (loss) per share attributable to common and limited common stockholders for the years presented (in thousands, except for share and per share data):

For the year ended December 31, 2023, in order to calculate diluted net income per share, the weighted average shares used to compute net income is adjusted by the effect of dilutive securities, including awards under the Plans. Diluted net income per share is computed by dividing the resulting net income by the weighted average number of fully diluted common and limited shares outstanding.

Since the Company was in a loss position for the years ended December 31, 2022 and 2021, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares and limited common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows:

(13)Equity Investments

(a) Nimbus

The Company previously provided collaboration services for Nimbus under the terms of a master services agreement executed on May 18, 2010, as amended. Collaboration agreements are separate from the transaction that resulted in equity ownership and related fees are paid in cash to the Company. Nimbus was previously recorded as an equity method investment under the HLBV method, as the entity is a limited liability company and the Company was determined to have significant influence due to the Company's collaboration with Nimbus on a number of drug discovery targets, as well as the Company's level of ownership in Nimbus. During the period ended September 30, 2023, the Company's equity ownership in Nimbus was diluted to the point that the Company no longer has significant influence over the entity. As the Company no longer has significant influence over Nimbus, after June 30, 2023, the equity investment in Nimbus is valued as a non-marketable equity security.

The carrying value of the Nimbus investment was $1,928 andzero as of December 31, 2023 and December 31, 2022, respectively. The Company has no obligation to fund Nimbus losses in excess of its investment. For the year ended December 31, 2023, the Company reported a realized gain of $147,213 on the Nimbus investment, which reflected the total cash distribution the Company was eligible to receive from Nimbus on account of Takeda's acquisition of Nimbus Lakshmi, Inc., a wholly-owned subsidiary of Nimbus, and its tyrosine kinase 2 inhibitor NDI-034858, as well as an unrealized gain of $1,928 due to the change in accounting method. The Company reportedno gains or losses on the Nimbus investment during the years ended December 2022 and 2021.

(b) Morphic

The Company accounts for its investment in Morphic Holding, Inc. (“Morphic”) at fair value based on the share price of Morphic’s common stock at the measurement date.

As of each of December 31, 2023 and December 31, 2022, the carrying value of the Company’s investment in Ajax was $1,700.

(d) Structure Therapeutics

In July 2021, the Company purchased 494,035 shares of Series B preferred stock of Structure Therapeutics for $2,000 in cash. In April 2022, the Company purchased an additional 148,210 shares of Series B preferred stock for $600 in cash. On February 7, 2023, Structure Therapeutics completed its IPO. Immediately upon the closing of Structure Therapeutics' IPO, all of the outstanding Series B preferred stock automatically converted into ordinary shares on aone-for-one basis. As of December 31, 2023, the Company owned 3,260,495 ordinary shares of Structure Therapeutics. The Company purchased 275,000 American Depository Shares ("ADS") at $15.00 per ADS in the IPO. Each ADS represents three ordinary shares.

Upon completion of Structure Therapeutics' IPO, the Company changed the valuation methodology used to value the Structure Therapeutics investment from an equity method investment under the HLBV method to an equity investment reported at fair value as the Company no longer exerts significant influence over Structure after the IPO. As there is a readily available market price for Structure Therapeutics' ADSs, the Company values its investment based on the closing price of Structure Therapeutics' ADSs as of the reporting date.

The carrying value of Structure Therapeutics was $55,509 and $1,629 as of December 31, 2023 and December 31, 2022, respectively.

(16)Segment Reporting

The Company has determined that its chief executive officer (“CEO”) is its chief operating decision maker (“CODM”). The Company’s CEO evaluates the financial performance of the Company based ontwo reportable segments: Software and Drug Discovery. The Software segment is focused on licensing the Company’s software to transform molecular discovery. The Drug Discovery segment is focused on building a portfolio of preclinical and clinical drug programs, internally and through collaborations.

The CODM reviews segment performance and allocates resources based upon segment revenue and segment gross profit of the Software and Drug Discovery reportable segments. Segment gross profit is derived by deducting operational expenditures, with the exception of research and development, sales and marketing, and general and administrative activities from U.S. GAAP revenue. Operational expenditures are expenditures made that are directly attributable to the reportable segment. These expenditures are allocated to the segments based on headcount. The reportable segment expenditures include compensation, supplies, and services from contract research organizations.

Certain cost items are not allocated to the Company’s reportable segments. These cost items primarily consist of non-drug discovery program related compensation and general operational expenses associated with the Company’s research and development, sales and marketing, and general and administrative. These costs are incurred by both segments and due to the integrated nature of the Company’s Software and Drug Discovery segments, any allocation methodology would be arbitrary and provide no meaningful analysis.

Segment revenue is primarily earned in the United States and there are no intersegment revenues. Additionally, the Company reports assets on a consolidated basis and does not allocate assets to its reportable segments for purposes of assessing segment performance or allocating resources.
