MARINUS PHARMACEUTICALS, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of the Business and Liquidity

We are a commercial-stage pharmaceutical company dedicated to the development of innovative therapeutics for the treatment of seizure disorders, including rare genetic epilepsies and status epilepticus. On March 18, 2022, the U.S. Food and Drug Administration (FDA) approved our new drug application (NDA) for the use of ZTALMY (ganaxolone) oral suspension for the treatment of seizures associated with Cyclin-dependent Kinase-like 5 (CDKL5) Deficiency Disorder (CDD) in patients 2 years of age and older. In June 2022, the U.S. Drug Enforcement Administration (DEA) published an interim final rule in the Federal Register placing ganaxolone and its salts in schedule V (CV) of the Controlled Substances Act (CSA), which rule became final on December 9, 2022. ZTALMY, our first FDA approved product, became available for commercial sale and shipment in the third quarter of 2022. On July 28, 2023, the European Commission (EC) granted marketing authorization for ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age. ZTALMY may be continued in patients 18 years of age and older. With the EC marketing authorization granted for ZTALMY, Orion Corporation (Orion), our commercialization partner for ZTALMY in Europe, has announced it has begun preparations for the launch of ZTALMY, including engaging in the required processes for obtaining pricing and reimbursement approval in the various European countries. The pricing and reimbursement process can be time consuming and may delay Orion’s commercial launch of ZTALMY in one or more European countries. We are developing ganaxolone for the treatment of other rare genetic epilepsies, including Tuberous Sclerosis Complex (TSC), and for the treatment of status epilepticus (SE). We are developing ganaxolone in formulations for two different routes of administration: intravenous (IV) and oral. The different formulations are intended to maximize potential therapeutic applications of ganaxolone for adult and pediatric patient populations, in both acute and chronic care, and for both acute in-hospital care and chronic at home-administration settings. While the precise mechanism by which ganaxolone exerts its therapeutic effects in the treatment of seizures is unknown, its anticonvulsant effects are thought to result from positive allosteric modulation of the gamma-aminobutyric acid type A (GABA_A) receptor in the central nervous system (CNS). Ganaxolone is a synthetic analog of allopregnanolone, an endogenous neurosteroid. Ganaxolone acts at both synaptic and extrasynaptic GABA_A receptors, a target known for its anti-seizure, antidepressant and anxiolytic potential.

COVID-19 affected our clinical operations and timelines. For example, our RAISE trial for refractory SE (RSE) is conducted in hospitals, primarily intensive care units in academic medical centers, which experienced high rates of COVID-19 admissions. Several of these sites participating in the RAISE trial experienced COVID-related difficulties, including staff turnover and the need to devote significant resources to patients with COVID-19, which resulted in site initiation and enrollment delays for the RAISE trial. Given these COVID-19-related challenges and the interruption in drug supply in mid-2022, we previously adjusted our expectation for our top-line data readout for the RAISE trial. In May 2022, we resumed screening and recruitment for the RAISE trial. We now expect our interim analysis with top-line data readout for the RAISE trial to be available in the first quarter of 2024.

Liquidity

Since inception, other than for the three months ended September 30, 2022 due to a one-time net gain from the sale of our Priority Review Voucher (PRV), we have incurred net losses and negative cash flows from our operations. We incurred a net loss of $66.7 million for the six months ended June 30, 2023. There is no assurance that profitable operations will be achieved in the future, and if achieved, could be sustained on a continuing basis. In addition, development activities, clinical and preclinical testing, and commercialization of ganaxolone (in indications other than CDD in the U.S.) will require significant additional financing. Our accumulated deficit as of June 30, 2023 was $497.2 million, and we expect to incur substantial losses in future periods. We plan to finance our future operations with a combination of proceeds from the issuance of equity securities, the issuance of debt, government funding, collaborations, licensing transactions and other commercial transactions or other sources, and revenues from product sales. We have not generated positive cash flows from operations, and there are no assurances that we will be successful in obtaining an adequate level of financing for the continued development and commercialization of ganaxolone.

7

Management’s operating plan, which underlies the analysis of our ability to continue as a going concern, involves the estimation of the amount and timing of future cash inflows and outflows. Actual results could vary from the operating plan. We follow the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 205-40, Presentation of Financial Statements—Going Concern, which requires management to assess our ability to continue as a going concern within one year after the date the financial statements are issued. We believe that our existing cash, cash equivalents and short-term investments as of June 30, 2023, will be sufficient to fund our operating expenses and capital expenditure requirements, as well as maintain the minimum cash balance required under our debt facility, for the one-year period after the date the financial statements are issued. However, we will need to secure additional funding in the future, from one or more equity or debt financings, government funding, collaborations, licensing transactions, other commercial transactions or other sources in order to carry out all of our commercialization and planned research and development activities with respect to ganaxolone.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of Marinus Pharmaceuticals, Inc. (a Delaware corporation) as well as the accounts of Marinus Pharmaceuticals Emerald Limited (an Ireland company incorporated in February 2021), a wholly owned subsidiary requiring consolidation. Marinus Pharmaceuticals Emerald Limited serves as a corporate presence in the European Union for regulatory purposes. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all information and disclosures necessary for a presentation of our financial position, results of operations and cash flows in conformity with generally accepted accounting principles in the U.S. (GAAP) for annual financial statements. In the opinion of management, these unaudited interim consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of our financial position and results of operations and cash flows for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for the full year. These unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2022 and accompanying notes thereto included in our Annual Report on Form 10-K filed with the SEC on March 9, 2023.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from such estimates.

Product Revenue, net

We recognize ZTALMY revenue in accordance with ASC 606 – Revenue from contracts with customers. Our revenue recognition analysis consists of the following steps: (i) identification of the promised goods in the contract; (ii) determination of whether the promised goods are performance obligations, including whether they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

Our first FDA approved product, ZTALMY, became available for commercial sale and shipment in the third quarter of 2022. We have three customers, one of which, Orsini Pharmaceutical Services, LLC (Orsini), a specialty pharmacy that dispenses ZTALMY directly to patients, represents over 99% of our ZTALMY revenue to date. Our contract with Orsini has a single performance obligation to deliver ZTALMY upon receipt of a purchase order, which is satisfied when Orsini receives ZTALMY. We recognize ZTALMY revenue at the point in time when control of ZTALMY is transferred to Orsini, which is upon delivery to Orsini. The transaction price that we recognize for

8

ZTALMY revenue includes an estimate of variable consideration. Shipping and handling costs to Orsini are recorded as selling, general and administrative expenses. The components of variable consideration include:

Trade Discounts and Allowances. We provide an incentive prompt payment discount to Orsini as explicitly stated in the contract with Orsini. This discount is recorded as a reduction of ZTALMY revenue and accounts receivable in the period in which the related ZTALMY revenue is recognized. We estimate the amount of variable consideration for all discounts and allowances using the expected value method.

Product Returns and Recall. We provide for ZTALMY returns in accordance with our Return Good Policy. We estimate the amount of ZTALMY that may be returned using the expected value method, and we present this amount as a reduction of ZTALMY revenue in the period the related ZTALMY revenue is recognized. In the event of a recall, we will promptly notify Orsini and will reimburse Orsini for direct administrative expenses incurred in connection with the recall as well as the cost of replacement product.

Government Rebates. We are subject to discount obligations under state Medicaid programs, Medicare, and the Tricare Retail Refund Program. We estimate reserves related to these discount programs and record these obligations in the same period the related revenue is recognized, resulting in a reduction of product revenue.

Patient Assistance. We offer a voluntary co-pay patient assistance program intended to provide financial assistance to eligible patients with a prescription drug co-payment required by payors and coupon programs for cash payors. The calculation of the current liability for this assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with ZTALMY that has been recognized as revenue but remains in the distribution channel inventories at the end of each reporting period.

Federal Contract Revenue

We recognize federal contract revenue from the BARDA Contract in the period in which the allowable research and development expenses are incurred, and receivables associated with this revenue are included within accounts receivable on our interim consolidated balance sheets. This revenue is not within the scope of ASC 606 – Revenue from contracts with customers.

Short-term Investments

We classify our short-term investments as available-for-sale securities, which include U.S. government agency debt securities and U.S. treasury debt securities with original maturities of greater than three months. These securities are carried at fair market value, with unrealized gains and losses reported in comprehensive loss and accumulated other comprehensive income within stockholders’ equity. All of our investments were short-term in nature as of June 30, 2023.

Accounts Receivable, net

Net trade receivables related to ZTALMY sales, which are recorded in net accounts receivable on the consolidated balance sheets, were approximately $1.8 million and $1.3 million as of June 30, 2023 and December 31, 2022, respectively. As of both June 30, 2023 and December 31, 2022, we had no allowance for doubtful accounts. An allowance for doubtful accounts is determined based on our assessment of the creditworthiness and financial condition of our customers, aging of receivables, as well as the general economic environment. Any allowance would reduce the net receivables to the amount that is expected to be collected. Payment terms for Orsini are approximately 30 days from the shipment date.

Excluding net trade receivables, accounts receivable represents amounts due to us under the BARDA contract for valid expenditures expected to be reimbursed to us under the terms of the BARDA contract and current amounts due to us from Orion Corporation (Orion) under the collaboration agreement (Note 12).

9

Inventory

Inventories are recorded using actual costs and may consist of raw materials (ganaxolone API), work in process and finished goods. We began capitalizing inventory related to ZTALMY subsequent to the March 2022 FDA approval of ZTALMY, as the related costs were expected to be recoverable through the commercialization and subsequent sale of ZTALMY. Prior to FDA approval of ZTALMY, costs estimated at approximately $2 million for commercially saleable product and materials were incurred and included in research and development expenses. As a result, cost of product revenues related to ZTALMY will initially reflect a lower average per unit cost of materials into approximately the first half of 2024, as previously expensed inventory is utilized for commercial production and sold to customers.

Debt Issuance Costs

Debt issuance costs incurred in connection with Note payable (Note 10) and revenue interest financing payable (Note 11) are amortized to interest expense over the term of the respective financing arrangement using the effective-interest method. Debt issuance costs, net of related amortization, are deducted from the carrying value of the related debt.

Contract Liabilities, net

When consideration is received, or such consideration is unconditionally due, from a customer prior to completing our performance obligation to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities expected to be recognized as revenue or a reduction of expense within the 12 months following the balance sheet date are classified as current liabilities. Contract liabilities not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as long-term liabilities. In accordance with ASC 210-20, our contract liabilities are partially offset by our contract assets as further discussed in Note 12.

Liability Related to Revenue Interest Financing and Non-Cash Interest Expense

In October 2022, we recognized a liability related to the Revenue Interest Financing Agreement with Sagard Healthcare Royalty Partners, LP (Sagard) under ASC 470-10 Debt and ASC 835-30 Interest - Imputation of Interest. The initial funds we received from Sagard pursuant to the terms of the Revenue Interest Financing Agreement were recorded as a liability and will be accreted under the effective interest method upon the estimated amount of future royalty payments to be made pursuant to the Revenue Interest Financing Agreement. The issuance costs were recorded as a direct deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period the liability will be repaid as further discussed in Note 11. We estimated the total amount of future product revenue to be generated over the life of the Revenue Interest Financing Agreement, and a significant increase or decrease in these estimates could materially impact the liability balance and the related interest expense. If the timing or amounts of any estimated future revenue and related payments change, we will prospectively adjust the effective interest and the related amortization of the liability and related issuance costs.

Collaboration and Licensing Revenue

We may enter into collaboration and licensing arrangements for research and development, manufacturing, and commercialization activities with counterparties for the development and commercialization of our product candidates. These arrangements may contain multiple components, such as (i) licenses, (ii) research and development activities, and (iii) the manufacturing of certain material. Payments pursuant to these arrangements may include non-refundable and refundable payments, payments upon the achievement of significant regulatory, development and commercial milestones, sales of product at certain agreed-upon amounts, and royalties on product sales. The amount of variable consideration is constrained until it is probable that the revenue is not at a significant risk of reversal in a future period.

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under a collaboration agreement, we perform the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether

10

they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

We must develop estimates and assumptions that require judgment to determine the underlying stand-alone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the stand-alone selling price may include such estimates as forecasted revenues and costs, development timelines, discount rates and probabilities of regulatory and commercial success. We also apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations, allocating transaction price to performance obligations within a contract, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time.

3. Cash, Cash Equivalents and Short-Term Investments

As of June 30, 2023, our cash and cash equivalents included $1.0 million of cash accounts in banking institutions and $126.8 million in money market funds. As of December 31, 2022, our cash and cash equivalents included $10.6 million of cash accounts in banking institutions and $230.0 million in money market funds. Our cash and cash equivalents are maintained in federally insured financial institutions in excess of the federally insured limit. Included in other assets at June 30, 2023 was $0.2 million of accrued interest receivable related to our short-term investments.

The following table provides details regarding our portfolio of short-term investments (in thousands) as of June 30, 2023:

	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value
U.S. Treasury securities	$	34,353	$	67	$	(154)	$	34,266
U.S. Government Agency securities		13,310		7		(34)		13,283
Total	$	47,663	$	74	$	(188)	$	47,549

We did not have any short-term investments as of December 31, 2022.

4. Fair Value Measurements

FASB accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (the exit price) in an orderly transaction between market participants at the measurement date. The accounting guidance outlines a valuation framework and creates a fair value hierarchy in order to increase the consistency and comparability of fair value measurements and the related disclosures. In determining fair value, we use quoted prices and observable inputs. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources.

The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

● Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

● Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

● Level 3 — Valuations based on inputs that are unobservable and models that are significant to the overall fair value measurement.

11

If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. As of June 30, 2023, all of our financial assets and liabilities were classified as Level 1 or Level 2 valuations. As of December 31, 2022, all of our financial assets and liabilities were classified as Level 1 valuations.

We estimate the fair values of our financial instruments categorized as Level 2 in the fair value hierarchy, including U.S. Treasury securities and U.S. Government Agency securities, by taking into consideration valuations obtained from third-party pricing services. The pricing services use industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, benchmark yields, issuer credit spreads, benchmark securities, and other observable inputs. We obtain a single price for each financial instrument and do not adjust the prices obtained from the pricing service.

The following fair value hierarchy table presents information about each major category of our financial assets and liabilities measured at fair value on a recurring basis (in thousands):

	Level 1		Level 2		Level 3		Total

7. Net Loss Per Share of Common Stock

Basic net loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted net loss per share of common stock includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred stock, stock options, and unvested restricted stock, which would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are not included in the calculation.

The pre-funded warrants to purchase common stock issued in connection with the November 2022 offering are included in the calculation of basic and diluted net loss per share as the exercise price of $0.001 per share is non-substantive and is virtually assured. The pre-funded warrants are more fully described in Note 8.

The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares of common stock outstanding as they would be anti-dilutive:

	June 30,
	2023	2022
Convertible preferred stock	—	860,000
Restricted stock awards and restricted stock units	1,489,119	758,217
Stock options	7,220,150	5,721,407
	8,709,269	7,339,624

8. Stockholders’ Equity

In 2005, we adopted the 2005 Stock Option and Incentive Plan (2005 Plan) that authorizes us to grant stock options, restricted stock and other equity-based awards. As of June 30, 2023, 577 options to purchase shares of common stock were outstanding pursuant to grants in connection with the 2005 Plan. No additional shares are available for issuance under the 2005 Plan. The amount, terms of grants, and exercisability provisions are determined and set by our board of directors.

Effective August 2014, we adopted our 2014 Equity Incentive Plan, as amended (2014 Plan), that authorizes us to grant stock options, restricted stock, and other equity-based awards, subject to adjustment in accordance with the 2014 Plan. As of June 30, 2023, 5,087,086 options to purchase shares of common stock were outstanding pursuant to grants in connection with the 2014 Plan, and 757,155 shares of common stock were available for future issuance. The amount, terms of grants, and exercisability provisions are determined and set by our board of directors. In accordance with the 2014 Plan, on January 1, 2023, the shares of common stock available for future grants under the 2014 Plan was increased by 2,020,111.

Stock Options

There were 7,220,150 stock options outstanding as of June 30, 2023 at a weighted average exercise price of $9.74 per share, including 2,132,487 stock options outstanding outside of the 2014 Plan, granted as inducements to new employees. During the six months ended June 30, 2023, 1,841,540 options were granted to employees and directors at a weighted average exercise price of $6.20 per share. Of the options granted, 1,532,390 options were granted pursuant to the 2014 Plan and 309,150 were granted outside of the 2014 Plan as inducements for new employees.

Restricted Stock and Restricted Stock Units

All issued and outstanding restricted shares of common stock are time-based, and become vested within two years of the grant date, pursuant to the 2014 Plan. Compensation expense is recorded ratably over the requisite service period. Compensation expense related to restricted stock is measured based on the fair value using the closing market price of our common stock on the date of the grant. As of June 30, 2023, we did not have any restricted shares of common stock outstanding.

During the six months ended June 30, 2023, we granted 959,996 restricted stock units, which vest within three years of the grant date, pursuant to the 2014 Plan. As of June 30, 2023, we had 1,489,119 restricted stock units outstanding.

Total compensation cost recognized for all stock options, restricted stock awards and restricted stock units in the statements of operations is as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2023		2022		2023		2022
Research and development	$	1,468	$	1,397	$	2,810	$	2,675
Selling, general and administrative		2,423		2,420		4,822		4,521
Total	$	3,891	$	3,817	$	7,632	$	7,196

Preferred Stock

As of June 30, 2023 all shares of our Series A Convertible Preferred Stock (Preferred Stock) had been converted and none remained outstanding. In the six months ended June 30, 2023, 4,300 shares of our Preferred stock were converted into 860,000 shares of our common stock.

Stock Issued in Connection with Ovid License Agreement

On March 29, 2022, pursuant to an exclusive patent license agreement with Ovid Therapeutics Inc. (Ovid), we issued 123,255 shares of our common stock to Ovid. The shares were issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the Securities Act) provided by Section 4(a)(2) of the Securities Act and Regulation D thereunder as sales by an issuer not involving any public offering (see Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds). The fair value of these shares is reflected in operating expenses for the six months ended June 30, 2022.

Underwritten Public Offering

In connection with an underwritten public offering in November 2022 and the closing of the related exercise of the underwriters’ option in December 2022, we issued a total of 12,421,053 shares of common stock and 2,105,264 pre-funded warrants (the Pre-funded Warrants) resulting in aggregate net proceeds, after underwriting discounts and commissions in the public offering and fees, of $64.5 million. The exercise price and the number of shares of common stock issuable upon exercise of each Pre-funded Warrant (the Warrant Shares) are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock as well as upon any distribution of assets, including cash, stock or other property, to our stockholders. The Pre-funded Warrants are exercisable at any time, will not expire and are exercisable in cash or by means of a cashless exercise. A holder of Pre-funded Warrants may not exercise such Pre-funded Warrants if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of Pre-funded Warrants may increase or decrease this percentage not in excess of 19.99% by providing at least 61 days’ prior notice to us.

9. Leases

We have entered into one operating lease for real estate. This lease has a term of 78 months, and includes renewal terms which can extend the lease term by 60 months, which we include in the lease term when it is reasonably certain that we will exercise the option. As of June 30, 2023, our operating lease had a remaining lease term of 27 months. The right-of-use (ROU) asset is included in “Other assets” on our interim consolidated balance sheets as of June 30, 2023 and December 31, 2022, and represents our right to use the underlying asset for the lease term. Our obligations to make lease payments are included in both “Accrued expenses” and “Other long-term liabilities” on our interim consolidated balance sheets as of June 30, 2023 and December 31, 2022. The ROU asset was initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred, less any lease incentives received. The ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received.  

As of June 30, 2023 and December 31, 2022, ROU assets were $1.1 million and $1.3 million, respectively, and operating lease liabilities were $1.7 million and $2.0 million, respectively. We have entered into various short-term operating leases, primarily for clinical trial equipment, with an initial term of twelve months or less. These leases are not recorded on our balance sheets. All operating lease expense is recognized on a straight-line basis over the lease term. During each of the three months ended June 30, 2023 and 2022, we recognized $0.1 million in total lease costs. During each of the six months ended June 30, 2023 and 2022, we recognized $0.3 million in total least costs. In all periods, we recognized less than $0.1 million in short-term lease costs related to short-term operating leases.

Because the rate implicit in each lease is not readily determinable, we use our incremental borrowing rate to determine the present value of the lease payments. The weighted average incremental borrowing rate used to determine the initial value of ROU assets and lease liabilities was 11.0%, derived from a corporate yield curve based on a synthetic credit rating model using a market signal analysis. We have certain contracts for real estate which may contain lease and non-lease components which we have elected to treat as a single lease component.

15

ROU assets for operating leases are periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize.  As of June 30, 2023 and December 31, 2022, we have not recognized any impairment losses for our ROU assets.

Maturities of operating lease liabilities as of June 30, 2023 were as follows (in thousands):

Remaining six months of 2023	$	414
2024		840
2025		642
Thereafter		—
		1,896
Less: imputed interest		(225)
Total lease liabilities	$	1,671
Current operating lease liabilities	$	681
Non-current operating lease liabilities		990
Total lease liabilities	$	1,671

10. Notes Payable

On May 11, 2021 (Closing Date) and as amended on May 17, 2021, May 23, 2022 and October 28, 2022 (Credit Agreement) we entered into the Credit Agreement with Oaktree Fund Administration, LLC as administrative agent (Oaktree) and the lenders party thereto (collectively, the Lenders) that provides for a five-year senior secured term loan facility in an aggregate original principal amount of up to $100.0 million, available to us in four tranches (collectively, the Term Loans).

Upon entering into the Credit Agreement in May 2021, we borrowed $15.0 million in term loans from the Lenders (Tranche A-1 Term Loans); upon receipt of written acceptance by the FDA of our NDA filing relating to the use of ganaxolone in CDD in September 2021 we borrowed $30.0 million of tranche A-2 term loans from the Lenders (Tranche A-2 Term Loans); and in March 2022, we borrowed $30.0 million in term loans from the Lenders that became available as a result of the approval by the FDA of ZTALMY oral suspension for the treatment of seizures associated with CDD in patients two years of age and older (Tranche B Term Loans). In May 2022, we entered into an amendment to extend the commitment date for the tranche C term loans (Tranche C Term Loans) commitment from June 30, 2023 to December 31, 2023, and to eliminate the commitment fees associated with the Tranche C Term Loans. Also in May 2022, we delivered to Oaktree a separate notice of commitment termination with respect to the tranche D term loans (Tranche D Term Loans) commitment. In October 2022, we entered into an amendment to, among other things, allow for the consummation of a revenue interest financing agreement (Revenue Interest Financing Agreement) with Sagard Health Royalty Partners (Sagard) and the transactions thereunder. In addition, the October 2022 amendment increased the exit fee due by us upon any repayment, whether as a prepayment or a scheduled repayment, of the principal of the loans under the Credit Agreement from 2.00% to 2.67%. Under the terms of the Credit Agreement, we may, at our sole discretion, borrow from the Lenders up to an additional $25.0 million in term loans subject to the following milestone event:

● Through December 31, 2023, $25.0 million of Tranche C Term Loans will be available for draw if we complete one or more financings (including through the issuance of common stock, convertible debt, subordinated debt, a synthetic royalty, or a sublicense) resulting in gross proceeds to us of at least $40.0 million and net proceeds to us of at least $36.0 million (Qualified Financing Condition). However, the availability of this tranche is also subject to either our current Phase 3 trial in RSE or a Phase 3 trial in TSC achieving statistical significance (p value < 0.05) across all primary endpoints and ganaxolone must be generally well tolerated, with a safety profile generally consistent with previous clinical trials. We do not currently anticipate data from either Phase 3 trial prior to December 31, 2023.

16

We satisfied the Qualified Financing Condition in connection with our November 2022 underwritten public offering; however, if we are unable to satisfy the remaining condition, we will not be able to draw down the remaining tranche of loans and may not be able to obtain alternative financing on commercially reasonable terms or at all. In addition, the Credit Agreement contains a minimum liquidity covenant that requires us to maintain cash and cash equivalents of at least $15.0 million from the funding date of the Tranche B Term Loans until the maturity of the Term Loans.

The Term Loans will be guaranteed by certain of our future subsidiaries (Guarantors). Our obligations under the Credit Agreement are secured by a pledge of substantially all of our assets and will be secured by a pledge of substantially all of the assets of the Guarantors.

The Term Loans mature on May 11, 2026 (Maturity Date). The Term Loans bear interest at a fixed per annum rate (subject to increase during an event of default) of 11.50%, and we are required to make quarterly interest payments until the Maturity Date. We are also required to make quarterly principal payments beginning on June 30, 2024 in an amount equal to 5.0% of the aggregate amount of the Term Loans outstanding on June 30, 2024, and continuing until the Maturity Date. On the Maturity Date, we are required to pay in full all outstanding Term Loans and other amounts owed under the Credit Agreement.

At the time of borrowing any tranche of the Term Loans, we are required to pay an upfront fee of 2.0% of the aggregate principal amount borrowed at that time. In addition, a commitment fee of 75 basis points per annum began to accrue on each of the tranche B, C, and D commitments for the period beginning 120 days after the funding date of the Tranche A-2 Term Loans, and continued until the applicable tranche was either funded or terminated, at which time the related commitment fees were due. The Tranche A-2 Term Loans were funded on September 27, 2021, and as such, we began accruing the commitment fees for tranche B, C, and D Term Loans 120 days later, on January 25, 2022. We drew down the additional $30.0 million of Tranche B Term Loans in March 2022, and paid less than $0.1 million in commitment fees related to Tranche B Term Loans. The May 2022 amendment eliminated the commitment fees related to the Tranche C Term Loans, and separately, we terminated the Tranche D Term Loans in May 2022.

We may prepay all or any portion of the Term Loans, and are required to make mandatory prepayments of the Term Loans from the proceeds of asset sales, casualty and condemnation events, and prohibited debt issuances, subject to certain exceptions. All mandatory and voluntary prepayments of the Term Loans are subject to prepayment premiums equal to (i) 4% of the principal prepaid plus a “make-whole” amount equal to the interest that would have accrued through May 11, 2023 if prepayment occurred on or before May 11, 2023, (ii) 4% of the principal prepaid if prepayment occurs after May 11, 2023 but on or before May 11, 2024, or (iii) 2% of the principal prepaid if prepayment occurs after May 11, 2024 but on or before May 11, 2025. If prepayment occurs after May 11, 2025, no prepayment premium is due.

We are also required to make mandatory prepayments of the Term Loans upon an event of default under the Credit Agreement resulting from the occurrence of a change of control.

In addition, we are required to pay an exit fee in an amount equal to 2.67% of all principal repaid, whether as a mandatory prepayment, voluntary prepayment, or a scheduled repayment. Prior to the October 2022 amendment to the Credit Agreement, the exit fee was 2.0%. The increase in the exit fee resulted in an additional $0.5 million of debt issuance costs that are classified as a contra-liability on the consolidated balance sheets and is being recognized as interest expense over the term of the loan using the effective interest method.

In addition to the minimum liquidity covenant, we are subject to a number of affirmative and restrictive covenants under the Credit Agreement, including limitations on our ability and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions, and enter into affiliate transactions, subject to certain exceptions. As of June 30, 2023, we were in compliance with all covenants.

Upon the occurrence of certain events, including but not limited to our failure to satisfy our payment obligations under the Credit Agreement, the breach of certain of our other covenants under the Credit Agreement, the occurrence of cross defaults to other indebtedness, or defaults related to enforcement action by the FDA or other

17

Regulatory Authority or recall of ganaxolone, Oaktree and the Lenders will have the right, among other remedies, to accelerate all amounts outstanding under the Term Loans and declare all principal, interest, and outstanding fees immediately due and payable.

In March 2022, we borrowed $30.0 million upon the approval by the FDA of ZTALMY for CDD and incurred debt issuance costs of $1.8 million, including the exit fee of $0.6 million, that are classified as contra-liabilities on our consolidated balance sheets and are being recognized as interest expenses over the term of the loan using the effective interest method.

In September 2021, we borrowed $30.0 million upon receipt of written acceptance by the FDA of our NDA filing relating to the use of ganaxolone in the treatment of CDD and incurred debt issuance costs of $1.2 million, including the exit fee of $0.6 million, that are classified as contra-liabilities on our consolidated balance sheets and are being recognized as interest expenses over the term of the loan using the effective-interest method.

In May 2021, we borrowed $15.0 million upon entering into the Credit Agreement and incurred debt issuance costs of $4.4 million, including the exit fee of $0.3 million, that are classified as a contra-liabilities on the consolidated balance sheet and are being recognized as interest expenses over the term of the loan using the effective-interest method.

For the six months ended June 30, 2023, we recognized interest expense of $5.3 million, of which $4.3 million was interest on the Term Loans and $1.0 million was non-cash interest expense related to the amortization of debt issuance costs.

11. Revenue Interest Financing Agreement

On October 28, 2022 (Closing Date), we entered into the Revenue Interest Financing Agreement with Sagard pursuant to which we received $32.5 million (Investment Amount) to provide funding for our development and commercialization of ganaxolone and related pharmaceutical products, including the commercial launch of ZTALMY, and for working capital and general administrative purposes.

In  exchange for the Investment Amount, we have agreed to make quarterly payments to Sagard (Payments) as follows: (i) for each calendar quarter from and after the Closing Date through and including the quarter ended June 30, 2026, an amount equal to 7.5% of (a) our U.S. net sales of ZTALMY and all other pharmaceutical products that contain ganaxolone (Net Sales), in each case with any dosage form, dosing regimen, or strength, or any improvements related

18

thereto (collectively, Included Products) and (b) certain other payments received by us in connection with the manufacture, development and sale of the Included Products in the U.S. (Other Included Payments, and, together with Net Sales, Product Revenue); and (ii) for each calendar quarter following the calendar quarter ended June 30, 2026, an amount equal to (x) 15.0% of the first $100 million in annual Product Revenue of the Included Products and (y) 7.5% of annual Product Revenue of the Included Products in excess of $100 million.

The Payments are subject to a hard cap equal to 190% of the Investment Amount (Hard Cap) or $61.8 million. Sagard’s right to receive payments will terminate when Sagard has received payments in respect of the Included Products, including any additional payments described below, equal to the Hard Cap. Further, we have the right to make voluntary prepayments to Sagard, and such payments will be credited against the Hard Cap.

If Sagard has not received aggregate payments equaling at least 100% of the Investment Amount by December 31, 2027 or at least 190% of the Investment Amount by December 31, 2032 (each, a Minimum Amount), then we will be obligated to make a cash payment to Sagard in an amount sufficient to gross up Sagard up to the applicable Minimum Amount within a specified period of time after each reference date.

The obligations under the Revenue Interest Financing Agreement, including the Payments, will be guaranteed by certain of our future subsidiaries that are required to become a party thereto as guarantors (Guarantors).  Our obligations under the Revenue Interest Financing Agreement and the guarantee of such obligations are secured, subject to customary permitted liens and other agreed upon exceptions and subject to an intercreditor agreement with Oaktree as administrative agent for the lenders under our credit agreement (as described below, the Credit Agreement), by a pledge of substantially all of our and the Guarantors’ assets that relate to, or are used or held for use for, the development, manufacture, use and/or commercialization of ZTALMY and all other pharmaceutical products that contain ganaxolone in the U.S., including the Product Revenue, pursuant to the terms of the Security Agreement dated as of the Closing Date by and among us, the Guarantors from time to time party thereto, and Sagard (Security Agreement).

At any time, we have the right, but not the obligation (Call Option), to repurchase all, but not less than all, of Sagard’s interest in the Payments at a repurchase price (Put/Call Price) equal to: (a) on or before the third anniversary of the Closing Date, 160% of the Investment Amount; (b) after the third anniversary but on or prior to the fourth anniversary of the Closing Date, 180% of the Investment Amount; and (c) after the fourth anniversary of the Closing Date, 190% of the Investment Amount, in each case, less the aggregate of all of our payments in respect of the Payments made to Sagard prior to such date.

The Revenue Interest Financing Agreement contains certain restrictions on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions.  In addition, the Revenue Interest Financing Agreement contains a financial covenant that requires us to maintain at all times cash and cash equivalents in certain deposit accounts in an amount at least equal to (i) from the Closing Date until the repayment of the loans under the Credit Agreement, $15.0 million and (ii) thereafter, $10.0 million.

In connection with the Revenue Interest Financing Agreement, on the Closing Date, we entered into an amendment to the Credit Agreement with Oaktree, which is fully described in Note 10.

Issuance costs pursuant to the Revenue Interest Financing Agreement consisted primarily of advisory and legal fees and totaled $2.6 million. These issuance costs were recorded as a direct deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period the liability will be repaid. For the six months ended June 30, 2023, we estimated an effective annual interest rate of approximately 19%. Over the course of the Revenue Interest Financing Agreement, the actual interest rate will be affected by the amount and timing of net ZTALMY revenue recognized and changes in the timing of forecasted net ZTALMY revenue. On a quarterly basis, we will reassess the expected timing of the net ZTALMY revenue, recalculate the amortization and effective interest rate and adjust the accounting prospectively as needed.

12. Collaboration Revenue

Orion Collaboration Agreement

In July 2021, we entered into a collaboration agreement (Orion Collaboration Agreement) with Orion. The Orion Collaboration Agreement falls under the scope of ASC Topic 808, Collaborative Arrangements (ASC 808) as both parties are active participants in the arrangement that are exposed to significant risks and rewards. While this arrangement is in the scope of ASC 808, we analogize to ASC 606 for some aspects of this arrangement, including for the delivery of a good or service (i.e., a unit of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue on the consolidated statements of operations.

Under the terms of the Orion Collaboration Agreement, we granted Orion an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights with respect to commercializing biopharmaceutical products incorporating our product candidate ganaxolone (Licensed Products) in the European Economic Area, the United Kingdom and Switzerland (collectively, the Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially in the indications of CDD, TSC and RSE. We will be responsible for the continued development of Licensed Products and regulatory interactions related thereto, including conducting and sponsoring all clinical trials, provided that Orion may conduct certain post-approval studies in the Territory. Orion will be responsible, at Orion’s sole cost and expense, for the commercialization of any Licensed Product in the Field in the Territory.

Under the terms of the Orion Collaboration Agreement, we received a €25.0 million ($29.6 million) upfront payment from Orion in July 2021. In connection with the upfront fee, we agreed to provide Orion with the results of a planned genotoxicity study on the M2 metabolite of ganaxolone, a “Combined Micronucleus & Comet study in vivo.” In May 2022, the final study report was received, which confirmed that no genotoxicity was found, as measured by formation of micronuclei in the bone marrow or comet morphology in the liver. In the event that the results of the study were positive, based on the criteria set forth in the study’s protocol, Orion would have had the right to terminate the Orion Collaboration Agreement within ninety (90) days after its receipt of the final study report, and we would have been required to refund Orion seventy-five percent (75%) of the upfront fee. We are eligible to receive up to an additional €97 million in research and development reimbursement and cash milestone payments based on specific clinical and commercial achievements, as well as tiered royalty payments based on net sales ranging from the low double-digits to high teens for the oral programs and the low double-digits to low 20s for the IV program. Also, as part of the overall arrangement, we have agreed to supply the Licensed Products to Orion at an agreed upon price.

The Orion Collaboration Agreement shall remain effective until the date of expiration of the last to expire Royalty Term, which is defined as the period beginning on the date of the first commercial sale Licensed Product in such country and ending on the latest to occur of (a) the tenth (10th) anniversary of the first commercial sale of Licensed Product in such country, (b) the expiration of the last-to-expire licensed patent covering the manufacture, use or sale of such Licensed Product in such country, and (c) the expiration of regulatory exclusivity period, if any, for such Licensed

20

Product in such country. The Orion Collaboration Agreement has a term of at least ten (10) years since a commercial sale has yet to occur. The Orion Collaboration Agreement allows for termination in certain specific events, such as material breach, in the event Orion challenges the validity, enforceability or scope of the licensed patent rights, termination for forecast failure, insolvency and force majeure, none of which are probable at contract inception.

In accordance with the guidance, we identified the following commitments under the arrangement: (i) exclusive rights to develop, use, sell, have sold, offer for sale and import any product comprised of Licensed Product (License), (ii) development and regulatory activities (Development and Regulatory Activities), and (iii) requirement to supply Orion with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these three commitments represent distinct performance obligations for purposes of recognizing revenue or reducing expense, which we will recognize such revenue or expense, as applicable, as we fulfill these performance obligations.

At contract inception, we determined that the non-refundable portion of the upfront payment plus the research and development reimbursement constitutes the transaction price as of the outset of the Orion Collaboration Agreement. The refundable portion of the upfront payment and the future potential regulatory and development milestone payments were fully constrained at contract inception as the risk of significant revenue reversal related to these amounts had not yet been resolved. During 2022, the refundable portion of the upfront payment was determined to be included in the transaction price as the final genotoxicity study on the M2 metabolite of ganaxolone was received as described above, and the remaining $12.7 million of the upfront payment was recorded as collaboration revenue in the year ended December 31, 2022. The achievement of the future potential milestones is not within our control and is subject to certain research and development success and therefore carries significant uncertainty. As a result of the July 2023 EC approval of ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age, we are now eligible under the Orion Collaboration Agreement to receive a commercial milestone payment of 10 million Euro, if commercial sales of ZTALMY commence in the Territory, due upon the earlier of (1) the first commercial sale of ZTALMY within two of a select set of countries consisting of Germany, France, Italy, Spain, and the United Kingdom or (2) the 18-month anniversary of the first commercial sale of ZTALMY in the Territory. We will reevaluate the likelihood of achieving these milestones at the end of each reporting period and adjust the transaction price in the period the risk is resolved. In addition, we will recognize any consideration related to sales-based milestones and royalties when the subsequent sales occur since those payments relate primarily to the License, which was delivered by us to Orion upon entering into the Orion Collaboration Agreement.

The transaction price was allocated to the three performance obligations based on the estimated stand-alone selling prices at contract inception. The stand-alone selling price of the License was based on a discounted cash flow approach and considered several factors including, but not limited to, discount rate, development timeline, regulatory risks, estimated market demand and future revenue potential using an adjusted market approach. The stand-alone selling price of the Development and Regulatory Activities and the Supply of Licensed Product was estimated using the expected cost-plus margin approach.

As of December 31, 2022, we allocated the transaction price to the performance obligations as described below and recorded the remaining $12.7 million of the upfront payment as collaboration revenue during the year ended December 31, 2022. During 2022, we amortized $1.1 million of the transaction price associated with the Development and Regulatory Services as a reduction of research and development costs. These reductions to transaction price resulted in a total contract liability of $15.1 million as of December 31, 2022. In accordance with ASC 210-20, the contract liability of $15.1 million was offset by a contract asset of $5.1 million related to the reimbursement of research and development costs, resulting in a net contract liability of $10.0 million as of December 31, 2022.

Transaction Price and Net Contract Liability as of December 31, 2022:

			Cumulative Collaboration
	Transaction		Revenue Recognized		Contract
	Price		as of December 31, 2022		Liability

Net Contract Liability					$	9,983

During the six months ended June 30, 2023, we amortized $0.8 million of the transaction price associated with the Development and Regulatory Services as a reduction of research and development costs. These reductions to the transaction price resulted in a total contract liability of $14.2 million as of June 30, 2023. In accordance with ASC 210-20, the contract liability of $14.2 million is offset by a contract asset of $4.0 million related to the reimbursement of research and development costs, resulting in a net contract liability of $10.2 million as of June 30, 2023.

Transaction Price and Net Contract Liability as of June 30, 2023:

	$	37,880	$	23,655		14,225
Less Total Contract Asset						3,992
Net Contract Liability					$	10,233

We incurred $2.0 million of incremental costs in connection with obtaining the Orion Collaboration Agreement. These contract acquisition costs were allocated consistent with the transaction price, resulting in $1.1 million of expense recorded to selling, general and administrative expense commensurate with the recognition of the License performance obligation and $0.9 million recorded as capitalized contract costs, included in other current assets and other assets, which are being amortized as Development and Regulatory Services and Supply of Licensed Product obligations are met.

We reevaluate the transaction price and the total estimated costs expected to be incurred to satisfy the performance obligations and adjust the deferred revenue at the end of each reporting period. Such changes will result in a change to the amount of collaboration revenue recognized and deferred revenue.

Tenacia Collaboration Agreement

On November 16, 2022 (Effective Date), we entered into a Collaboration and Supply Agreement (Tenacia Collaboration Agreement) with Tenacia Biotechnology (Shanghai) Co., Ltd. (Tenacia). The Tenacia Collaboration Agreement falls under the scope of ASC Topic 808, Collaborative Arrangements (ASC 808) as both parties are active participants in the arrangement that are exposed to significant risks and rewards. While this arrangement is in the scope of ASC 808, we analogize to ASC 606 for some aspects of this arrangement, including for the delivery of a good or service (i.e., a unit of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue on the consolidated statements of operations.

22

Under the terms of the Tenacia Collaboration Agreement, we granted Tenacia an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights to develop, commercialize and otherwise exploit certain products incorporating certain oral and intravenous formulations of our product candidate ganaxolone (Licensed Products) in Mainland China, Hong Kong, Macau and Taiwan (collectively, Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially for the treatment of cyclin-dependent kinase-like 5 deficiency disorder, tuberous sclerosis complex and SE (including refractory and established SE) (collectively, the Initial Indications). The collaboration can be expanded to include additional indications and formulations of ganaxolone pursuant to a right of first negotiation.

Under the terms of the Tenacia Collaboration Agreement, Tenacia agreed to pay us an upfront cash payment of $10 million (the Upfront Fee) within forty-five (45) days after the Effective Date, which was paid in December 2022. In addition to the Upfront Fee, Tenacia has agreed to make cash payments to us upon the achievement of certain development, regulatory and sales-based milestones related to (i) the Initial Indications and (ii) the first new formulation or pro-drug of ganaxolone or any back-up compound of ganaxolone in a new indication (Selected Product) for which the parties amend the Tenacia Collaboration Agreement in connection with Tenacia’s exercise of its right of first negotiation and for which there is no other Licensed Product approved in China (for clarity, the milestone payments under this clause (ii) will only apply to one Selected Product), up to an aggregate amount of $256 million. Of the milestones, $15 million relates to regulatory approvals with separate milestones related to each of oral and intravenous formulations and the Selected Product, and an aggregate of $241 million of sales-based milestones are connected to annual revenue thresholds specific to each of the oral, intravenous and Selected Product formulations of ganaxolone. Tenacia has further agreed to pay us tiered royalty payments based on annual net sales of Licensed Products ranging from the low double digits to the mid-teens for each of the oral formulation, intravenous formulation and Selected Product formulation of Licensed Products. Tenacia’s obligations to pay royalties to us with respect to sales of a Licensed Product in each particular jurisdiction of the Territory will commence on the date of first commercial sale in such jurisdiction and expire upon the latest of (i) ten years following the first commercial sale of such Licensed Product in such jurisdiction, (ii) the expiration of the last-to-expire valid claim of any licensed patent rights that covers such Licensed Product in such jurisdiction and (iii) the expiration of all regulatory exclusivities for such Licensed Product in such jurisdiction. Royalty payments are subject to reduction in specified circumstances as set forth in the Tenacia Collaboration Agreement, including if net sales decrease by a certain percentage after the introduction of a generic product.

Tenacia will be primarily responsible for the development of Licensed Products in the Territory and regulatory interactions related thereto, including conducting and sponsoring clinical studies in the Field in the Territory to support regulatory filings in the Territory. All regulatory approvals filed by Tenacia in the Territory will be in the name of and owned by us unless otherwise required by applicable law, in which case such regulatory approvals would be in the name of and owned by Tenacia for the benefit of us. We and Tenacia agreed to enter into clinical and commercial supply agreements pursuant to which we will supply Tenacia with its requirements of Licensed Products necessary for Tenacia to develop and commercialize Licensed Products in the Field in the Territory. The parties entered into the clinical and commercial supply agreement in May 2023. The agreement contains pricing, delivery, acceptance, payment, termination, forecasting, and other terms consistent with the Tenacia Collaboration Agreement, as well as certain quality assurance, indemnification, liability and other standard industry terms. Tenacia will be responsible for, at Tenacia’s sole cost and expense, obtaining regulatory approval and commercializing the Licensed Product in the Field in Mainland China.

The term of the Tenacia Collaboration Agreement extends for so long as royalties are payable anywhere in the Territory. Subject to the terms of the Tenacia Collaboration Agreement, (i) for a specified period of time after the Effective Date, Tenacia may terminate the Tenacia Collaboration Agreement in its entirety for any or no reason upon written notice to us, and (ii) either party may terminate the Tenacia Collaboration Agreement for the other party’s material breach following a cure period or insolvency.

In accordance with the guidance, we identified the following commitments under the arrangement: (i) grant to Tenacia the exclusive rights to develop, commercialize and otherwise exploit Licensed Product in the Field in the Territory (License) and (ii) requirement to supply Tenacia with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these two commitments represent distinct performance obligations for purposes of recognizing revenue or reducing expense, which it will recognize such revenue or expense, as applicable, as it fulfills these performance obligations.

23

The transaction price was allocated to the two performance obligations based on the estimated stand-alone selling prices at contract inception. The stand-alone selling price of the License was based on a discounted cash flow approach and considered several factors including, but not limited to, discount rate, development timeline, regulatory risks, estimated market demand and future revenue potential using an adjusted market approach. The stand-alone selling price of the Supply of Licensed Product was estimated using the expected cost-plus margin approach.

As of December 31, 2022, we allocated the transaction price to the performance obligations as described below. There was no activity in the three and six months ended June 30, 2023. The cumulative collaboration revenue recognized as of June 30, 2023 is $3.0 million, which was the $3.0 million transaction price associated with the License as revenue for the year ended December 31, 2022. No license revenue was recorded in the three and six months ended June 30, 2023. There was a total contract liability of $7.0 million as of both June 30, 2023 and December 31, 2022. In accordance with ASC 210-20, the contract liability of $7.0 million is offset by a contract asset of $0.7 million, resulting in a net contract liability of $6.3 million as of both June 30, 2023 and December 31, 2022.

Transaction Price and Net Contract Liability as of June 30, 2023 and December 31, 2022:

			Cumulative Collaboration
	Transaction		Revenue Recognized		Contract
	Price		as of June 30, 2023 and December 31, 2022		Liability

	$	10,000	$	2,998		7,002
Less Total Contract Asset						700
Net Contract Liability					$	6,302

In December 2022, we incurred $1.0 million of incremental costs in obtaining the Tenacia Collaboration Agreement. These contract acquisition costs were allocated consistent with the transaction price, resulting in $0.1 million of expense recorded to General and administrative expense and $0.2 million recorded to cost of collaboration revenue in the period ended December 31, 2022, commensurate with the recognition of the License performance obligation, and $0.7 million recorded as capitalized contract costs, which will be amortized as Supply of License Product obligations are met.

We reevaluate the transaction price and the total estimated costs expected to be incurred to satisfy the performance obligations and adjust the deferred revenue at the end of each reporting period. Such changes will result in a change to the amount of collaboration revenue recognized and deferred revenue.

Biologix Distribution and Supply Agreement

In May 2023, we entered into an exclusive distribution and supply agreement (Biologix Agreement) with Biologix FZCo (Biologix), whereby Biologix has the right to distribute and sell ganaxolone in Algeria, Bahrain, Egypt, Iraq, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Tunisia and United Arab Emirates. In exchange for distribution rights, we will be the exclusive supplier of our products to Biologix on terms set forth in the respective agreements in exchange for a negotiated purchase price for the products. Upon execution of the Biologix Agreement, we received an upfront payment of $0.5 million which is to be amortized over the term of the agreement. We may be entitled to additional fees upon regulatory milestones. In the three and six months ended June 30, 2023, we recorded less than $0.1 million of collaboration revenue related to the Biologix Agreement.

Overview

We are a commercial-stage pharmaceutical company dedicated to the development of innovative therapeutics for the treatment of seizure disorders, including rare genetic epilepsies and status epilepticus. On March 18, 2022, the U.S. Food and Drug Administration (FDA) approved our new drug application (NDA) for the use of ZTALMY (ganaxolone) oral suspension CV for the treatment of seizures associated with Cyclin-dependent Kinase-like 5 (CDKL5) Deficiency Disorder (CDD) in patients 2 years of age and older. ZTALMY, our first FDA approved product, became available for commercial sale and shipment to patients in the third quarter of 2022. On July 28, 2023, the European Commission (EC) granted marketing authorization for ZTALMY for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age. ZTALMY may be continued in patients 18 years of age and older. We are developing ganaxolone for the treatment of other rare genetic epilepsies, including Tuberous Sclerosis Complex (TSC), and for the treatment of status epilepticus (SE). We are developing ganaxolone in formulations for two different routes of administration: intravenous (IV) and oral. The different formulations are intended to maximize potential therapeutic applications of ganaxolone for adult and pediatric patient populations, in both acute and chronic care, and for both acute in-hospital care and chronic at home-administration settings. While the precise mechanism by which ganaxolone exerts its therapeutic effects in the treatment of seizures is unknown, its anticonvulsant effects are thought to result from positive allosteric modulation of the gamma-aminobutyric acid type A (GABA_A) receptor in the central nervous system (CNS). Ganaxolone is a synthetic analog of allopregnanolone, an endogenous neurosteroid. Ganaxolone acts at both synaptic and extrasynaptic GABA_A receptors, a target known for its anti-seizure, antidepressant and anxiolytic potential.

COVID-19

COVID-19 affected our clinical operations and timelines. For example, our RAISE trial for refractory SE (RSE) is conducted in hospitals, primarily intensive care units in academic medical centers, which experienced high rates of COVID-19 admissions. Several of these sites participating in the RAISE trial experienced COVID-related difficulties, including staff turnover and the need to devote significant resources to patients with COVID-19, which resulted in site initiation and enrollment delays for the RAISE trial. Given these COVID-19-related challenges and the interruption in drug supply in mid-2022, we previously adjusted our expectation for our top-line data readout for the RAISE trial. In May 2022, we resumed screening and recruitment for the RAISE trial. We now expect our interim analysis with top-line data readout for the RAISE trial to be available in the first quarter of 2024.

ZTALMY was approved by the FDA in March 2022 for the treatment of seizures associated with CDD in patients 2 years of age and older. ZTALMY, our first FDA approved product, became available for commercial sale and shipment to patients in the third quarter of 2022. We recorded ZTALMY net product revenue of $4.2 million and $7.6 million in the three and six months ended June 30, 2023, respectively. On July 28, 2023, the EC granted marketing authorization for ZTALMY for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age. ZTALMY may be continued in patients 18 years of age and older. With the EC marketing authorization granted for ZTALMY, Orion Corporation (Orion), our commercialization partner for ZTALMY in Europe, has announced it has begun preparations for the launch of ZTALMY, including engaging in the required processes for obtaining pricing and reimbursement approval in the various European countries. The pricing and reimbursement process can be time consuming and may delay Orion’s commercial launch of ZTALMY in one or more European countries.

CDD is a serious and rare genetic disorder that is caused by a mutation of the CDKL5 gene, located on the X chromosome. CDD is a severely debilitating and potentially fatal genetic condition, which occurs with an estimated frequency of 1:40,000 live births in the U.S. It predominantly affects females and is characterized by early onset, difficult to control seizures and severe neurodevelopmental impairment. The CDKL5 gene encodes proteins essential for normal brain structure and function. Most children affected by CDD have neurodevelopmental deficits such as difficulty walking, talking and taking care of themselves. Many also suffer from scoliosis, gastrointestinal dysfunction or sleep disorders. Genetic testing is available to determine if a patient has a mutation in the CDKL5 gene.

In June 2017, we were granted FDA orphan drug designation for ganaxolone for the treatment of CDD. The designation provides the drug developer with a seven year period of U.S. marketing exclusivity, as well as tax credits for clinical research costs, the ability to apply for annual grant funding, clinical research trial design assistance and waiver of Prescription Drug User Fee Act filing fees. Additionally, in November 2019, the European Medicines Agency’s (EMA) Committee for Orphan Medicinal Products (COMP) granted orphan drug designation for ganaxolone for the treatment of CDD. Prior to the grant of the marketing authorization, the COMP is required to determine whether the orphan drug designation criteria are still met. On 26 May 2023, the COMP provided a positive opinion to maintain the orphan drug designation for ganaxolone in CDD in the EU. In July 2020, the FDA granted Rare Pediatric Disease Designation (RPD Designation) for ganaxolone for the treatment of CDD. The FDA grants RPD Designation for diseases that affect fewer than 200,000 people in the U.S. and in which the serious or life-threatening manifestations occur primarily in individuals 18 years of age and younger. The approval of ZTALMY in CDD is based on data from a Phase 3 double-blind placebo-controlled trial (Marigold study), in which 101 patients were randomized and treated with ZTALMY. Clinical trial patients receiving ZTALMY showed a median 30.7% reduction in 28-day major motor seizure frequency, compared to a median 6.9% reduction for those receiving placebo, achieving the trial’s primary endpoint (p=0.0036). At two years in the open label extension phase of the Marigold study, patients (n=50) treated with ZTALMY experienced a median 48.2% reduction in major motor seizure frequency. These data suggest that patients who remain on treatment long-term may demonstrate continued reductions in seizure frequency. The most common adverse events in the double-blind portion of the Marigold study were somnolence (36.0% in the ganaxolone group compared to 15.7% in the placebo group), pyrexia (18.0% and 7.8%, respectively) and salivary hypersecretion (6.0% and 2.0%, respectively).

We own families of patents and pending patent applications that claim certain formulations of ganaxolone and cover certain therapeutic uses of ganaxolone, including for treating CDD. The 20-year terms for patents, and applications that issue as patents, in these families run from 2026 through 2042, absent any available patent term adjustments or extensions. We have also licensed from Ovid certain patents that claim certain therapeutic uses of ganaxolone for the treatment of CDD. The licensed patents include a granted U.S. patent, and pending applications in the U.S. and Europe. The 20-year term for these licensed patents and applications that issue as patents will run through 2037, absent any available patent term adjustments.

U.S. Commercial Strategy. Since ZTALMY was approved by the FDA, we have been focused on the implementation and execution of an integrated launch plan to make ZTALMY available to U.S. CDD patients through a specialty pharmacy. Key launch strategies have included and continue to include: (1) establishing our supply chain network and quality management system to assure product is available to patients; (2) driving clinical awareness of ZTALMY as the first and only FDA approved product indicated specifically for seizures associated with CDD; (3) deploying our field sales force to target physicians who treat this rare pediatric patient population; (4) engaging commercial and government payers with the objective of obtaining insurance coverage; and (5) developing our internal capabilities (such as Finance, Human Resources, Information Technology, Data Analytics and Compliance) to support our first launch as a commercial company.

U.S. Marketing Strategy.  Our marketing strategy is to reinforce that seizures are central to the constellation of CDD symptoms, establish ZTALMY as central to the comprehensive management of seizures associated with CDD, and ensure that patients have seamless access to ZTALMY from prescription through fulfillment. Our marketing campaign for ZTALMY is active, and our integrated commercial launch activities initiated in the third quarter of 2022.

U.S. Sales Strategy.  Our U.S. commercial sales force includes 16 regional account managers experienced in rare disease. Our field force is targeting identified key accounts and centers of excellence for CDD. Based on our market research, we estimate the addressable patient population for ZTALMY in CDD in the U.S. is approximately 2,000 patients. As this is the first product approved by the FDA specifically for seizures associated with CDD and the International Classification of Diseases, Tenth Revision (ICD10) code for CDD was established in 2021, there is limited data available for this specific market. We have strengthened both our market access and field force teams, and both payer and customer engagement are ongoing.

U.S. Market Access.  We have established a cross-functional payer and reimbursement account team with the objective of obtaining and maintaining reimbursement (coverage) of ZTALMY in the U.S. We are focusing our efforts on reimbursement from commercial payers where pharmacy benefit managers (PBMs) control the majority of commercial pharmacy-benefit lives and government payers, primarily Medicaid for the target population for CDD.  We expect approximately 50% of the CDD patient population will access primary coverage through Fee-for-Service or Managed Medicaid, with the remaining approximately 50% accessing primary coverage through commercial payers, with the top PBMs having significant influence. The prescribing and fulfillment process for ZTALMY is managed through ZTALMY One™, a comprehensive patient support program. Enrollment in the program offers various support and information to help caregivers and patients prescribed ZTALMY access their ZTALMY prescription and assist in determining eligibility for and access to co-pay support or free drug programs.

U.S. Specialty Pharmacy.  We are utilizing Orsini Pharmaceutical Services, LLC (Orsini), a specialty pharmacy, to provide services for U.S. patients, including patient enrollment, benefit verification and investigation, prior authorization support, patient education and drug counseling, dispensing of product and shipment coordination. We recorded our first sales of ZTALMY to Orsini in the third quarter of 2022.

U.S. Specialty Distributor. We are utilizing ASD Specialty Healthcare, LLC (ASD), a specialty distributor, to provide distribution services in the U.S. in connection with ZTALMY to institutional inpatient pharmacies, U.S. governmental customers, including any Department of Veterans Affairs or Department of Defense sites, and Kaiser Permanente facilities.

Infrastructure.  We continue to enhance our internal capabilities and processes to support a commercial stage company.  We have implemented a healthcare compliance program to guide our compliance with rules and regulations regarding pharmaceutical sales. 

Manufacture of Commercial Supply. We have executed commercial supply agreements for ganaxolone active pharmaceutical ingredient (API) with our current manufacturer and also with our current supplier for finished bulk drug product. Additionally, we have executed a master supply agreement with a second API supplier to undertake certain process development activities and, if successful, provide commercial supplies of API and/or API intermediates.

Regulated as a Controlled Substance in the U.S. On June 1, 2022, the Drug Enforcement Administration (DEA) published an interim final rule in the Federal Register placing ganaxolone and its salts in schedule V of the Controlled Substances Act (CSA), which rule became final December 9, 2022. Under the CSA, drugs are classified into five (5) distinct categories or schedules depending upon the drug’s acceptable medical use and the drug’s abuse or dependency potential. Schedule V is defined by the DEA as drugs with lower potential for abuse than schedule IV and consist of preparations containing limited quantities of certain narcotics. ZTALMY became available for commercial sale and shipment to patients in the third quarter of 2022. As a controlled substance, ganaxolone is subject to the applicable CSA requirements such as registration, security, recordkeeping and reporting, storage manufacturing, distribution, importation and other requirements.

FDA Post-Marketing Requirements. In connection with FDA approval of ZTALMY for CDD, we have several post-marketing commitments. The Phase 1 renal impairment study commitment was completed and submitted to the FDA in May 2022, the Phase 1 hepatic impairment study and the thorough QTc study were completed and submitted to the FDA in December 2022 and the extractable/leachable study results on the container closure system were submitted to the FDA in July 2023. The remaining post-marketing requirements include: 2-year carcinogenicity studies of ganaxolone and the major human unconjugated plasma metabolite, M2, in rats; a 26-week carcinogenicity of ganaxolone in transgenic mice; a juvenile animal toxicity study of M2 in rats; a CNS distribution study of the M47 metabolite in rats; and in vitro studies to assess the drug interaction potential of the M47 metabolite. We expect to be able to complete these remaining required FDA studies within the requested FDA timeframe.

Marketing Authorization Application

In August 2021, the Committee for Medicinal Products for Human Use (CHMP) of the EMA granted our request for accelerated assessment of ganaxolone for the treatment of seizures associated with CDD. The marketing authorization application (MAA) for ganaxolone was submitted to the EMA on October 11, 2021 and on October 28, 2021 we received formal notification from the EMA that the CDD MAA was validated. With this validation, the EMA began its formal review of the MAA under the centralized procedure. On May 26, 2023, the CHMP adopted a positive opinion recommending approval of and on July 28, the EC approved ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age. ZTALMY may be continued in patients 18 years of age and older. The EC decision is applicable to all 27 EU member states plus Iceland, Norway and Liechtenstein. ZTALMY is the first treatment in the EU indicated for the treatment of seizures associated with CDD.

EC Post-Authorization Measures. In connection with the EC approval of ZTALMY for CDD, we have several post-marketing authorization measures including; submission of the clinical study report (CSR) for Study 1042-HME-1001 and the final Study 1042-CDD-3001 CSR with the open-label trial completion, participate in Study LLF001 (CANDID observational study) and provide annual updates, participate in the CDD-IPR-CDD-0 CDKL5 Deficiency Disorder International Patient Registry and provide six monthly updates, conduct a toxicity study with a sediment dwelling organism and an updated Environmental Risk Assessment, develop a sodium benzoate-free suspension, assess the compatibility of the oral suspension with food, drinks, enteral tubes, shake time and stand time, conduct a Ganaxolone Steady-State Metabolite Study, M17 in vitro drug-drug interaction (DDI) Studies, a M17 in vivo PK Study with Brain Penetrance, a 26-Week Oral Gavage Toxicity Study of M2, a M2 Embryo-fetal Development study, a 26-week Oral Gavage Carcinogenicity Study of ganaxolone and M2. The EMA also requested weight of evidence (WoE) assessments to evaluate the need for a 2-year carcinogenicity study in rats with ganaxolone, a 2-year carcinogenicity study in rats with M2, and a juvenile toxicity study with M2. We expect to be able complete the required studies within the requested EMA timeframe.

Our Pipeline

We are developing ganaxolone in indications where there is a mechanistic rationale for ganaxolone to provide a benefit, including the following indications:

Status Epilepticus (SE)

SE is a life-threatening condition characterized by continuous, prolonged seizures or rapidly recurring seizures without intervening recovery of consciousness. If SE is not treated urgently, permanent neuronal damage may occur, which contributes to high rates of morbidity and mortality. Patients with SE who do not respond to first-line benzodiazepine treatment are classified as having ESE and those who then progress to and subsequently fail at least one second-line antiepileptic drug (AED) are classified as having RSE. In RSE, synaptic GABA_A receptors are internalized into the neuron, resulting in decreased responsiveness to drugs such as benzodiazepines. RSE unresponsiveness to one or more second-line AEDs requires treatment with IV anesthesia to terminate seizures and prevent neuronal injury and other complications. The IV anesthetic is increased to a level that induces deep coma and is maintained at that rate for 24 hours or more. SE that recurs following an attempted wean of IV anesthesia is classified as super refractory status epilepticus (SRSE). In April 2016, we were granted FDA orphan drug designation for the IV formulation of ganaxolone for the treatment of SE, which includes RSE.

In January 2021, we enrolled the first patient in the Phase 3 pivotal RAISE trial. The RAISE trial is a randomized, double-blind, placebo-controlled clinical trial in patients with RSE. We expect approximately 70 trial sites in hospitals, primarily across the U.S. and Canada, to participate. The RAISE trial is designed to enroll approximately 124 patients, to be randomized to receive ganaxolone or placebo added to standard of care. With this number of patients, the trial is designed to provide over 90% power to detect a 30% efficacy difference between ganaxolone and placebo. We reached alignment with the FDA on a protocol amendment, including a proposal for a potential interim analysis when two-thirds of the patients (approximately 82) have completed the trial. We anticipate reaching the enrollment target for the interim analysis and announcing topline data in the first quarter of 2024. We believe positive interim RAISE trial results could be adequate for regulatory filing purposes in RSE.

The co-primary endpoints for the RAISE trial are (1) proportion of patients with RSE who experience seizure cessation within 30 minutes of treatment initiation without other medications for SE treatment, and (2) proportion of patients with no progression to IV anesthesia for 36 hours following initiation of the trial drug. In June 2022, we

31

announced that we amended the protocol for the RAISE trial to expand eligibility criteria to support recruitment. We broadened the inclusion criteria to permit patients previously treated with up to 18 hours of high-dose IV anesthesia to qualify for the trial, rather than excluding patients treated with anesthetics at high doses for any duration. We believe this will facilitate the enrollment of patients transferred to the ICU from other hospitals or the emergency room, who may already have received high doses of anesthetic medication for less than 18 hours.

Several academic medical centers and intensive care units participating in the RAISE trial experienced COVID-related difficulties, including staff turnover and the need to devote significant resources to patients with COVID-19, which resulted in site initiation and enrollment delays. Additionally, in February 2022, we temporarily paused the RAISE trial after routine monitoring of stability batches of clinical supply material indicated that it became necessary to reduce the shelf life to less than the anticipated 24 months to meet product stability testing specifications. We notified the FDA of this issue and our plans to proactively pause the trial, and we subsequently provided additional information to the FDA to support resuming trial activities. In May 2022, we announced that the trial had resumed utilizing new batches of the current IV formulation of ganaxolone, and we implemented a reduced shelf life of 12 months. In agreement with the FDA, ganaxolone clinical supplies with the current IV formulation will be stored under refrigerated conditions for the entire duration of clinical use. Based on ongoing stability data, the shelf life of the current IV formulation has been updated to 18 months under refrigerated conditions, which was submitted in the subsequent IND amendment in February 2023. We manufactured the IV ganaxolone formulation with a new buffer and are targeting a shelf life of 24 months at room temperature, pending the results of ongoing stability monitoring. The FDA agreed that in principle a buffer change in the ganaxolone IV formulation is acceptable but requested additional information be submitted prior to use of the new formulation in the clinical trials. An IND amendment was submitted to the FDA in May 2023, and we are in the process of resupplying sites with the new formulation, which we believe will not require refrigeration and is expected to have a two-year shelf life.

Planning continues for a separate Phase 3 RSE trial to support an MAA in Europe (RAISE II trial). We gained alignment on the trial design at a meeting with the EMA in the first quarter of 2021. Due to the delay in clinical trial supply mentioned for the RAISE trial, the RAISE II trial initiation is planned for the second half of 2023. The RAISE II trial will be a double blind, placebo-controlled pivotal registration trial expected to enroll 70 patients who have failed first-line benzodiazepine treatment and at least one second-line AED. Patients will receive either ganaxolone or placebo, administered in combination with a standard-of-care second-line AED. The simultaneous administration of a standard-of-care AED with the trial drug is expected to provide data complementary to that from the RAISE trial. There are two additional key differences between the RAISE and RAISE II trials. First, rather than specifying progression to IV anesthesia as a treatment failure, under the RAISE II protocol any escalation of care will constitute a treatment failure. This could be IV anesthesia or another second-line IV AED. Second, the primary analysis for the RAISE II trial will be a responder analysis, with response defined as SE cessation within 30 minutes and no escalation of care within 36 hours, rather than the co-primary endpoints in the RAISE trial, which require statistical significance to be achieved independently on both the 30-minute and 36-hour outcomes.

The FDA has indicated alignment on the overall trial design for a third SE trial, the RESET trial, a Phase 2 trial evaluating ganaxolone in the treatment of ESE, for which completion of the first cohort is expected by the end of 2023. The RESET trial will enroll patients with convulsive SE presenting to emergency departments and will be conducted under Exception from Informed Consent (EFIC) guidelines. The RESET trial will consist of two phases: an initial open-label, dose optimization phase and a subsequent double-blind placebo-controlled phase. In the open-label portion of the trial, sequential cohorts will receive IV ganaxolone for varying durations and at different doses. The dosing for each cohort will depend on the treatment effect and tolerability seen in the previous one, with the expected optimal dose and duration of ganaxolone incorporated in the double-blind phase of the trial to follow. We expect that the double-blind placebo-controlled phase will enroll approximately 80 ESE patients randomized equally to IV ganaxolone or placebo added to a standard-of-care AED. The primary efficacy endpoint will be the absence of electrographic (rapid EEG) evidence of SE or recurrence of generalized convulsions at 1 hour after the initiation of treatment.

We do not have a clinical trial ongoing in SRSE, however, physicians have requested ganaxolone for 19 patients in SRSE under emergency investigational new drug (EIND) applications that have been approved by the FDA.

32

In September 2021, the U.S. Patent and Trademark Office (USPTO) granted us a patent on a method of treating SE, including dosing regimens. This issued patent expires in 2040. That patent is a member of a patent family we own that includes pending patent applications that claim certain therapeutic regimens for the treatment of SE, including RSE, using intravenous ganaxolone. The USPTO granted us a second patent for SE on June 20, 2023, which includes claims related to our clinical therapeutic regimen for the treatment of SE using IV ganaxolone. These new claims cover therapeutic regiments in which high doses of ganaxolone are administered, which we believe is relevant for some patients, and strengthens our intellectual property portfolio for the treatment of SE, including SRSE, using ganaxolone.

In July 2022, the USPTO issued a patent to Ovid with claims that encompass our product candidate for the treatment of SE. On March 15, 2023, we filed a petition seeking post-grant review (PGR) of Ovid’s U.S. Patent No. 11,395,817 with the U.S. Patent and Trademark Office Patent Trial and Appeal Board (PTAB). Our petition for PGR argues that the claims of U.S. Patent No. 11,395,817 are unpatentable on multiple grounds as lacking novelty under 35 USC § 102 and being obvious under 35 USC § 103 and, if not invalid under § 102 or § 103, as lacking enablement under 35 USC § 112. Ovid filed a preliminary response to our petition on June 20, 2023, and the PTAB has until September 20, 2023 to decide whether to grant our petition and institute the PGR. If the PGR is instituted and we do not prevail, the decision can be appealed to the Court of Appeals for the Federal Circuit. If an appeal is not successful, our ability to challenge the Ovid patent in court will be limited in certain respects.

Ovid may file a lawsuit against us alleging infringement of its patents. Any such proceedings, in the PTAB or courts, regardless of their outcome, would likely result in the expenditure of significant financial resources and the diversion of management’s time and resources. In addition, any such proceeding may cause negative publicity, adversely impact patients, and we may be prohibited from marketing or selling ganaxolone for SE, RSE and ESE during such proceedings or if we are not successful in such proceedings. If Ovid does decide to bring an infringement lawsuit, we do not expect that it will be filed before a commercial launch of ganaxolone for SE, RSE or ESE based upon the “safe harbor” provisions of the Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Act). We may need to acquire or obtain a license to the Ovid patents to market or sell ganaxolone for SE, RSE and ESE, which may not be available on commercially acceptable terms or at all. If we are not able to acquire the Ovid patents or negotiate a license on acceptable terms, and if our product is determined to infringe Ovid’s patents and the patents are determined to be valid, then we may be forced to pay Ovid royalties, damages and costs, or we may be prevented from commercializing ganaxolone for SE, RSE and ESE altogether, which would have a material adverse impact on our business.

Tuberous Sclerosis Complex (TSC)

TSC is a rare genetic disorder that causes non-malignant tumors in the brain, skin, kidney, heart, eyes, and lungs. Rarely, patients may develop malignant tumors of the kidney, breast or thyroid gland. The condition is caused by inherited mutations in either the TSC1 or TSC2 gene. It occurs with a frequency of approximately 1:6,000 live births, with a mutation being found in 85% of patients. While the disease phenotype can be extremely variable, epilepsy occurs with a frequency of up to 85%. TSC is a leading cause of genetic epilepsy, often manifesting in the first year of life as either focal seizures or infantile spasms. There are currently few disease-specific treatments approved for seizures in TSC. Orphan drug designation for ganaxolone for the treatment in TSC was granted by the FDA in August 2021 and by the EMA in October 2021.

In August 2021, we announced top-line data from our open-label Phase 2 trial (CALM trial) evaluating the safety and efficacy of adjunctive oral ganaxolone in 23 patients with seizures associated with TSC. The CALM trial enrolled 23 patients ages 2 to 32 who entered a four-week baseline period followed by a 12-week treatment period, during which they received up to 600 mg of ganaxolone (oral liquid suspension) three times a day. Patients who met eligibility criteria were able to continue ganaxolone treatment during a 24-week extension. The primary endpoint was the percent change in 28-day TSC-associated seizure frequency during the 12-week treatment period relative to the four-week baseline period. Secondary outcome measures included the percentage of patients experiencing a greater than or equal to 50% reduction in 28-day TSC-associated seizure frequency through the end of the 12-week treatment period compared to the 4-week baseline period.

33

The primary endpoint showed a median 16.6% reduction in 28-day frequency of TSC-associated seizures relative to the four-week baseline period. A secondary endpoint showed that the proportion of patients that achieved at least a 50% seizure reduction was 30.4%. During the trial, patients with focal seizures (n=19) showed a median 25.2% reduction in focal seizure frequency. Ganaxolone was generally well-tolerated with somnolence reported as the most common AE. In addition, one serious adverse event (SAE) of worsening seizures occurred, which was assessed by the investigator as treatment related. Four patients discontinued the trial due to AEs. Additionally, the data from the trial suggested that in patients on concomitant Epidiolex, early elevation of ganaxolone blood levels occurred and appeared to be linked to greater somnolence. The interpretation of these findings is limited by the small sample size and open-label design of the trial. A formal Phase 1 drug-drug interaction trial was completed in the fourth quarter of 2022, demonstrating a lack of significant interaction between ganaxolone and Epidiolex. Additionally, the titration schedule for all subjects in the Phase 3 TSC trial has been adjusted to maximize tolerability.

In response to our request for an End of Phase 2 meeting with the FDA regarding a proposed Phase 3 TSC trial, the FDA provided written responses to our questions in lieu of a meeting. We believe the written responses show overall alignment on the clinical development plan in TSC. We believe that, based on the FDA’s written responses, and with the FDA approval of CDD, a single trial could serve as necessary support for regulatory approval for TSC in the U.S. In response to our request for Protocol Assistance, which is a special form of scientific advice available for developers of designated orphan medicines for rare diseases, the EMA provided written feedback in December 2021 in lieu of a meeting. We believe the written responses from the EMA, like those from the FDA, show overall alignment on the clinical development plan in TSC. After commencing site initiations in the first quarter of 2022 and dosing the first patient in the second quarter of 2022, we are actively enrolling patients in the U.S. and Western Europe for this global Phase 3 randomized, double blind, placebo-controlled trial (TrustTSC trial) of adjunctive ganaxolone in approximately 160 patients. We expect to expand the trial to include up to 90 sites, including several TSC centers of excellence, predominantly in the U.S., Western Europe, Canada, Australia, China and Israel. The primary endpoint for the TrustTSC trial is percent change in 28-day frequency of TSC-associated seizures. We plan to announce top-line data from the TrustTSC trial by mid-2024.

In July 2023, the USPTO granted us a patent on a method of treating TSC-related epilepsy by administering oral ganaxolone. This issued patent expires in 2040. This patent is a member of a patent family we own that includes pending patent applications that claim certain therapeutic regimens for the treatment of TSC.

Second-Generation Formulation, Clinical Development in Lennox-Gastaut Syndrome (LGS) and Prodrug Development

Top-line data from a single ascending dose (SAD) Phase 1 trial in healthy volunteers utilizing the first candidate for a second-generation formulation of ganaxolone demonstrated linear pharmacokinetic (PK) properties at doses of up to 1200 mg and PK characteristics that may allow for twice-daily dosing. Additionally, as shown in the figure below, while area under the curve (AUC), which quantifies the total exposure to drug over a period of time, demonstrated linear kinetics through the full range dosed, C_max, which is the maximum serum concentration that a drug achieves after administration, showed less substantial increases at the higher end of the dose range. These findings suggest that efficacy could be improved using higher doses of ganaxolone without corresponding increases in dose-related side effects, such as somnolence. This would permit greater individualization of dosing to optimize efficacy and tolerability.

34

We believe that the data support further clinical development of this formulation of ganaxolone. We received preliminary feedback from the FDA on the design of the multiple ascending dose (MAD) trial. The FDA requested additional data, including the SAD clinical trial report, prior to initiating the MAD trial. The information was provided to the FDA and, upon review, the FDA indicated that we may proceed with the proposed trial. We initiated the MAD trial in the third quarter of 2023 with preliminary data expected by the end of 2023.

The development of ganaxolone prodrug compounds continues to advance, with lead oral and IV candidates selected, and Phase 1 data targeted for 2024.

We plan to pursue the development of the second-generation formulation of ganaxolone for LGS, a severe form of epilepsy that typically begins between one and eight years of age. Affected children have neurodevelopmental impairments and intractable seizures, including focal, atonic, tonic, generalized tonic-clonic and atypical absence seizures. In March 2023, the FDA granted orphan drug designation to ganaxolone for the treatment of LGS. This designation applies to the active moiety of ganaxolone and is not dependent on the formulation. Given the overlap in seizure types and etiologies with other disorders where ganaxolone has potential to reduce seizures, such as CDD and TSC, we believe that LGS represents a promising opportunity for ganaxolone development. We expect to finalize the clinical program design for LGS in the first quarter of 2024, pending results of the MAD trial that we initiated in the third quarter of 2023.

Operations

Our operations to date have consisted primarily of organizing and staffing our company, developing ganaxolone, including conducting preclinical studies and clinical trials, and raising capital. We have funded our operations primarily through sales of equity and debt securities. ZTALMY, our first FDA approved product, became available for commercial sale and shipment to patients in the third quarter of 2022. We recorded $4.2 million and $7.6 million of net ZTALMY sales in the three and six months ended June 30, 2023, respectively. Since inception, other than for the three months ended September 30, 2022 due to a one-time net gain from the sale of our Priority Review Voucher (PRV), we have incurred net losses and negative cash flows from our operations. We have generated limited product revenues, and there is no assurance that profitable operations will be achieved in the future, and if achieved, could be sustained on a continuing basis. We incurred net losses of $31.9 million and $66.7 million for the three and six months ended June 30, 2023, respectively. We incurred net losses of $39.4 million and $58.8 million for the three and six months ended June 30, 2022 respectively. Our accumulated deficit as of June 30, 2023 was $497.2 million, and we expect to continue to incur substantial losses in future periods. We anticipate that our operating expenses will increase substantially as we carry out all of our planned commercialization and continued research and development activities with respect to ganaxolone.

We anticipate that our expenses will increase substantially as we:

● conduct multiple later stage clinical trials in targeted indications;

● continue the research, development and scale-up manufacturing capabilities to optimize ganaxolone and dose forms for which we may obtain regulatory approval;

● continue to establish and implement sales, marketing and distribution capabilities to commercialize ganaxolone;

● conduct other preclinical studies and clinical trials to support the filing of NDAs with the FDA, MAAs with the EMA and other marketing authorization filings with regulatory agencies in other countries;

● acquire the rights to other product candidates and fund their development;

● maintain, expand and protect our global intellectual property portfolio;

35

● hire additional clinical, manufacturing, scientific and commercial personnel; and

● add operational, financial and management information systems and personnel, including personnel to support our drug development efforts.

We had cash, cash equivalents and short-term investments of $175.3 million as of June 30, 2023. We believe that our existing cash, cash equivalents and short-term investments as of June 30, 2023 will be sufficient to fund our operating expenses and capital expenditure requirements, as well as maintain the minimum cash balance required under our debt facility, into the second half of 2024. However, we will need to secure additional funding in the future, from one or more equity or debt financings, government funding, collaborations, licensing transactions, other commercial transactions or other sources in order to carry out all of our commercialization and planned research and development activities with respect to ganaxolone.

Financial Overview

Product Revenue, net

Our first FDA approved product, ZTALMY, became available for commercial sale and shipment to patients in the third quarter of 2022. We have three customers, one of which, Orsini Pharmaceutical Services, LLC (Orsini), a specialty pharmacy that dispenses ZTALMY directly to patients, represents over 99% of our ZTALMY revenue to date. Our contract with Orsini has a single performance obligation to deliver ZTALMY upon receipt of a purchase order, which is satisfied when Orsini receives ZTALMY. We recognize ZTALMY revenue at the point in time when control of ZTALMY is transferred to Orsini, which is upon delivery to Orsini. The transaction price that we recognize for ZTALMY revenue includes an estimate of variable consideration. Shipping and handling costs to Orsini are recorded as selling, general and administrative expenses. The components of variable consideration include:

Trade Discounts and Allowances. We provide an incentive prompt payment discount to Orsini as explicitly stated in the contract with Orsini. This discount is recorded as a reduction of ZTALMY revenue and accounts receivable in the period in which the related ZTALMY revenue is recognized. We estimate the amount of variable consideration for all discounts and allowances using the expected value method.

Product Returns and Recall. We provide for ZTALMY returns in accordance with our Return Good Policy. We estimate the amount of ZTALMY that may be returned using the expected value method, and we present this amount as a reduction of ZTALMY revenue in the period the related ZTALMY revenue is recognized. In the event of a recall, we will promptly notify Orsini and will reimburse Orsini for direct administrative expenses incurred in connection with the recall as well as the cost of replacement product.

Government Rebates. We are subject to discount obligations under state Medicaid programs, Medicare, the Tricare Retail Refund Program. We estimate reserves related to these discount programs and record these obligations in the same period the related revenue is recognized, resulting in a reduction of product revenue.

Patient Assistance. We offer a voluntary co-pay patient assistance program intended to provide financial assistance to eligible patients with a prescription drug co-payment required by payors and coupon programs for cash payors. The calculation of the current liability for this assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with ZTALMY that has been recognized as revenue but remains in the distribution channel inventories at the end of each reporting period.

Federal Contract Revenue

In September 2020, we entered into a contract (BARDA Contract) with the Biomedical Advanced Research and Development Authority (BARDA), a division of the U.S. Department of Health and Human Services’ Office of the Assistant Secretary for Preparedness and Response. Under the BARDA Contract, we received an award of up to an estimated $51 million for development of IV-administered ganaxolone for the treatment of RSE. The BARDA Contract

36

provides for funding to support, on a cost-sharing basis, the completion of a Phase 3 clinical trial of IV-administered ganaxolone in patients with RSE, which covers the RAISE trial, funding of pre-clinical studies to evaluate IV-administered ganaxolone as an effective treatment for RSE due to chemical nerve gas agent exposure, and funding of certain ganaxolone manufacturing scale-up and regulatory activities. In March 2022, we entered into an amendment with BARDA to extend the end date of our base performance period for funding under the BARDA Contract from September 1, 2022 to December 31, 2023. In September 2022, we entered into an amendment with BARDA that, among other things, (i) provides for the exercise of BARDA’s option under the BARDA Contract to support U.S. onshoring of the manufacturing capabilities for ganaxolone API (Option 2), (ii) changes the end date of our performance period under Option 2 from December 31, 2026 to July 31, 2025, (iii) increases the government cost share amount under Option 2 from approximately $11.5 million to approximately $12.3 million, and (iv) increases our cost share amount under Option 2 from approximately $4.9 million to approximately $5.3 million.

The BARDA Contract consists of an approximately two-year base period, which was extended through December 31, 2023, during which BARDA will provide up to approximately $21 million of funding for the RAISE trial on a cost share basis and funding of additional preclinical studies of ganaxolone in nerve agent exposure models. Following successful completion of the RAISE trial and preclinical studies in the contract period the BARDA Contract provides for approximately $31 million of additional BARDA funding for three options in support of ganaxolone manufacturing, supply chain, clinical, regulatory and toxicology activities, including the $12.3 million exercise of Option 2 as described above. Under the BARDA Contract, we will be responsible for cost sharing in the amount of approximately $33 million and BARDA will be responsible for approximately $52 million if all development options are completed. The contract period-of-performance (base period plus option exercises) is up to approximately five years.

We recognize federal contract revenue from the BARDA Contract in the period in which the allowable research and development expenses are incurred. We expect federal contract revenue to increase as the costs associated with our RAISE trial increase.

Collaboration Revenue

In July 2021, we entered into a collaboration agreement (Orion Collaboration Agreement) with Orion Corporation (Orion). Under the terms of the Orion Collaboration Agreement, we granted Orion an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights with respect to commercializing biopharmaceutical products incorporating ganaxolone (Licensed Products) in the European Economic Area, the United Kingdom and Switzerland (collectively, the Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially in the indications of CDD, tuberous sclerosis complex (TSC) and RSE.

Under the terms of the Orion Collaboration Agreement, we received a €25.0 million ($29.6 million) upfront payment from Orion in July 2021. We are eligible to receive up to an additional €97 million in R&D reimbursement and cash milestone payments based on specific clinical and commercial achievements. Also, as part of the overall arrangement, we have agreed to supply the Licensed Products to Orion at an agreed upon price.

We identified the following commitments under the arrangement: (i) exclusive rights to develop, use, sell, have sold, offer for sale and import any product comprised of Licensed Product (License); (ii) development and regulatory activities (Development and Regulatory Activities); and (iii) requirement to supply Orion with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these three commitments represent distinct performance obligations for purposes of recognizing revenue and will recognize license and collaboration revenue or a reduction of expense as we fulfill each performance obligation.

On November 16, 2022, we entered into a Collaboration and Supply Agreement (Tenacia Collaboration Agreement) with Tenacia Biotechnology (Shanghai) Co., Ltd. (Tenacia). Under the terms of the Tenacia Collaboration Agreement, we granted Tenacia an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights to develop, commercialize and otherwise exploit certain products incorporating certain oral and intravenous formulations of the our product candidate ganaxolone (Licensed Products) in Mainland China, Hong Kong, Macau and Taiwan (collectively, Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially for the treatment of CDD, TSC and SE (including refractory and established SE)

37

(collectively, Initial Indications). The collaboration can be expanded to include additional indications and formulations of ganaxolone pursuant to a right of first negotiation.

Under the terms of the Tenacia Collaboration Agreement, Tenacia agreed to pay us an upfront cash payment of $10 million (Upfront Fee) within forty-five (45) days after the Effective Date, which was received in December 2022. In addition to the Upfront Fee, Tenacia has agreed to make cash payments to us upon the achievement of certain development, regulatory and sales-based milestones related to (i) the Initial Indications and (ii) the first new formulation or pro-drug of ganaxolone or any back-up compound of ganaxolone in a new indication (Selected Product) for which the parties amend the Tenacia Collaboration Agreement in connection with Tenacia’s exercise of its right of first negotiation and for which there is no other Licensed Product approved in China (for clarity, the milestone payments under this clause (ii) will only apply to one Selected Product), up to an aggregate amount of $256 million. Of the milestones, $15 million relates to regulatory approvals with separate milestones related to each of oral and intravenous formulations and the Selected Product, and an aggregate of $241 million of sales-based milestones are connected to annual revenue thresholds specific to each of the oral, intravenous and Selected Product formulations of ganaxolone. Tenacia has further agreed to pay us tiered royalty payments based on annual net sales of Licensed Products ranging from the low double digits to the mid-teens for each of the oral formulation, intravenous formulation and Selected Product formulation of Licensed Products. Tenacia’s obligations to pay royalties to us with respect to sales of a Licensed Product in each particular jurisdiction of the Territory will commence on the date of first commercial sale in such jurisdiction and expire upon the latest of (i) ten years following the first commercial sale of such Licensed Product in such jurisdiction, (ii) the expiration of the last-to-expire valid claim of any licensed patent rights that covers such Licensed Product in such jurisdiction and (iii) the expiration of all regulatory exclusivities for such Licensed Product in such jurisdiction. Royalty payments are subject to reduction in specified circumstances as set forth in the Tenacia Collaboration Agreement, including if net sales decrease by a certain percentage after the introduction of a generic product.

Tenacia will be primarily responsible for the development of Licensed Products in the Territory and regulatory interactions related thereto, including conducting and sponsoring clinical studies in the Field in the Territory to support regulatory filings in the Territory. All regulatory approvals filed by Tenacia in the Territory will be in the name of and owned by us unless otherwise required by applicable law, in which case such regulatory approvals would be in the name of and owned by Tenacia for the benefit of us. We and Tenacia agreed to enter into clinical and commercial supply agreements pursuant to which we will supply Tenacia with its requirements of Licensed Products necessary for Tenacia to develop and commercialize Licensed Products in the Field in the Territory. The parties entered into the clinical and commercial supply agreement in May 2023. The agreement contains pricing, delivery, acceptance, payment, termination, forecasting, and other terms consistent with the Tenacia Collaboration Agreement, as well as certain quality assurance, indemnification, liability and other standard industry terms. Tenacia will be responsible for, at Tenacia’s sole cost and expense, obtaining regulatory approval and commercializing the Licensed Product in the Field in Mainland China.

The term of the Tenacia Collaboration Agreement extends for so long as royalties are payable anywhere in the Territory. Subject to the terms of the Tenacia Collaboration Agreement, (i) for a specified period of time after the Effective Date, Tenacia may terminate the Tenacia Collaboration Agreement in its entirety for any or no reason upon written notice to us, and (ii) either party may terminate the Tenacia Collaboration Agreement for the other party’s material breach following a cure period or insolvency.

In accordance with the guidance, we identified the following commitments under the arrangement: (i) grant to Tenacia the exclusive rights to develop, commercialize and otherwise exploit Licensed Product in the Field in the Territory (License) and (ii) requirement to supply Tenacia with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these two commitments represent distinct performance obligations for purposes of recognizing revenue or reducing expense, which it will recognize such revenue or expense, as applicable, as it fulfills these performance obligations.

We have also entered into agreements for commercialization of ganaxolone in other territories with (i) NovaMedica LLC (NovaMedica), whereby NovaMedica has the right to market and sell ganaxolone in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan, and (ii) Biologix FZCo (Biologix), whereby Biologix has the right to distribute and sell ganaxolone in

38

Algeria, Bahrain, Egypt, Iraq, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Tunisia and United Arab Emirates. In exchange for distribution rights, we will be the exclusive supplier of our products to NovaMedica and Biologix on terms set forth in the respective agreements in exchange for a negotiated purchase price for the products. As of the first quarter 2023, we have initiated limited sales of ZTALMY to NovaMedica to support on-going early access programs associated with patients from the Marigold trial. We continue to assess opportunities in other markets to further expand the distribution and commercialization of ganaxolone globally.

Research and Development Expenses

Our research and development expenses consist primarily of costs incurred for the development of ganaxolone, which include:

● employee-related expenses, including salaries, benefits, travel and stock-based compensation expense;

● expenses incurred under agreements with clinical research organizations (CROs) and investigative sites that conduct our clinical trials and preclinical studies;

● the cost of acquiring, developing and manufacturing clinical trial materials;

● facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, and other supplies and services;

● costs associated with preclinical activities and regulatory operations; and

● costs associated with developing new formulations and prodrugs of ganaxolone.

We expense research and development costs when we incur them. We record costs for some development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations and information our vendors provide to us.

We have and will incur substantial costs beyond our present and planned clinical trials in order to file an NDA and Supplemental NDAs, or MAAs outside the U.S., for ganaxolone for various clinical indications, and in each case, the nature, design, size and cost of further clinical trials and other studies will depend in large part on the outcome of preceding studies and trials and discussions with regulators. It is difficult to determine with certainty the costs and duration of our current or future clinical trials and preclinical studies, or if, when or to what extent we will generate revenue from the commercialization and sale of ganaxolone if we obtain regulatory approval. We may never succeed in achieving regulatory approval for ganaxolone. The duration, costs and timing of clinical trials and development of ganaxolone will depend on a variety of factors, including the uncertainties of future clinical trials and preclinical studies, uncertainties in clinical trial enrollment rate and significant and changing government regulation.

In addition, the probability of success for our clinical programs will depend on numerous factors, including competition, manufacturing capability and commercial viability. See the “Risk Factors” section of our Annual Report on Form 10-K filed on March 9, 2023 for more information with respect to such factors. Our commercial success depends upon attaining significant market acceptance, if approved, among physicians, patients, healthcare payers and the medical community. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success, as well as an assessment of commercial potential.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist principally of salaries and related costs for executive, commercial and other administrative personnel and consultants, including stock-based compensation and travel expenses. Other selling, general and administrative expenses include professional fees for commercial, legal, patent review, consulting and accounting services. Selling, general and administrative expenses are expensed when incurred.

39

Cost of Product Revenue

Cost of product revenue includes the cost of inventory sold, which includes direct manufacturing and supply chain costs. Also included in cost of product revenue are royalty payments owed to Purdue Neuroscience Company (Purdue) and Ovid in accordance with the respective license agreements. We began capitalizing inventory related to ZTALMY subsequent to the March 2022 FDA approval of ZTALMY, as the related costs were expected to be recoverable through the commercialization and subsequent sale of ZTALMY. Prior to FDA approval of ZTALMY, costs estimated at approximately $2 million for commercially saleable product and materials were incurred and included in research and development expenses. As a result, cost of product revenues related to ZTALMY will initially reflect a lower average per unit cost of materials into approximately the first half of 2024, as previously expensed inventory is utilized for commercial production and sold to customers.

Cost of IP License Fee

In March 2022, we entered into an exclusive patent license agreement (License Agreement) with Ovid. Under the License Agreement, we have an exclusive, non-transferable (except as provided in the License Agreement), royalty-bearing, sublicensable license under certain of Ovid’s patent(s) and patent applications to develop, make, have made, commercialize, promote, distribute, sell, offer for sale and import, ganaxolone, including any analogues or derivatives, including its salts, and pharmaceutical formulations of the foregoing (Licensed Products), in the U.S., the member states of the EU, Iceland, Lichtenstein, Norway, the United Kingdom, and Switzerland (Territory) for the treatment of CDD in humans (Field). Under the License Agreement, we have the sole right and responsibility for, and control over, all development, manufacturing, and commercialization activities, including all regulatory activities, with respect to the Licensed Products in the Field in the Territory. In addition, all regulatory approvals and related filings with respect to the Licensed Products in the Field in the Territory will be in the name of, and be owned solely by, us. We were required, at Ovid’s option exercisable in accordance with the License Agreement, to (i) pay to Ovid the sum of $1.5 million in cash; or (ii) issue to Ovid 123,255 shares of our common stock, which option to obtain shares of our common stock was exercisable within the five-business day period following the filing of our Annual Report on Form 10-K for the year ended December 31, 2021 on March 24, 2022. On March 29, 2022, we issued 123,255 shares of our common stock to Ovid, per Ovid’s option in accordance with the License Agreement. As such, we recorded $1.2 million of IP license fee expenses related to the Ovid License Agreement in the six months ended June 30, 2022.

The License Agreement also provides for payment of royalties by us to Ovid in the low single digits on net sales by us, our affiliates and sublicensees, of Licensed Products in the Field in the Territory. Such royalties are subject to reduction in the event of generic competition in accordance with the License Agreement. We may terminate the License Agreement at any time without cause on thirty days’ prior written notice. Either party may terminate the License Agreement for the other party’s material breach or insolvency subject to certain cure periods. Also, Ovid has the right to terminate the License Agreement if there has not been a first commercial sale of any Licensed Products in the Field in the Territory on or before June 30, 2025. In the event of termination, all licenses granted under the License Agreement will terminate.

Interest Income

Interest income consists principally of interest income earned on cash and cash equivalents and investment balances.

Interest Expense

Interest expense consists of interest expense and amortization of debt discount related to our Notes Payable and our Revenue Interest Financing Payable.

Other Income (Expense), net

Other expense and income consists principally of gains or losses on disposal of fixed assets held for sale, foreign currency transactions, and fair value adjustments.

40

Benefit for Income Taxes

We recorded a $1.5 million benefit for income taxes due to the identification of a discrete item of tax determined upon preparation of our 2022 tax return in the three and six months ended June 30, 2023. We did not have a provision for income taxes in the three or six months ended June 30, 2022.

Results of Operations

Product Revenue, net

We recognized $4.2 million and $7.6 million of ZTALMY net product revenue for the three and six months ended June 30, 2023, respectively. As ZTALMY, our first FDA approved product, became available for commercial sale and shipment to patients in the third quarter of 2022, we did not recognize any product revenue in the three and six months ended June 30, 2022.

Federal Contract Revenue

We recognized $1.8 million and $8.9 million of federal contract revenue for the three and six months ended June 30, 2023 as a result of the BARDA Contract. We recognized $1.8 million and $3.3 million of federal contract revenue for the three and six months ended June 30, 2022, respectively, as a result of the BARDA Contract. The increase in the six months ended June 30, 2023 compared to the 2022 period primarily relates to expenses incurred in connection with on-going validation of a new third-party supplier of ganaxolone API.

Collaboration Revenue

Collaboration revenue, which resulted from our agreement with Biologix, was less than $0.1 million for each of the three and six months ended June 30, 2023. No collaboration revenue was recorded in the three months ended June 30, 2022. Collaboration revenue was $12.7 million for the six months ended June 30, 2022 a result of revenue recognition related to the previously refundable upfront payment pursuant to the Orion Collaboration Agreement. In connection with the upfront fee related to the Orion Collaboration Agreement, we agreed to provide Orion with the results of an ongoing genotoxicity study. In May 2022, the final study report showed that no genotoxicity was found, as measured by formation of micronuclei in the bone marrow or comet morphology in the liver. As a result of the study’s findings, we are not required to refund Orion any of the upfront fee and Orion does not have the right to terminate the Orion Collaboration Agreement based on the study outcome. During the six months ended June 30, 2022, we allocated the previously refundable portion of the upfront payment to the transaction price and recognized the related revenue.

41

Research and Development Expenses

We record direct research and development expenses, consisting principally of external costs, such as fees paid to investigators, consultants, central laboratories and CROs in connection with our clinical trials, and costs related to manufacturing, to specific product development programs. We do not allocate costs related to purchasing clinical trial materials, employee and contractor-related costs, costs associated with our facility expenses, including depreciation or other indirect costs, to specific product programs because these costs are deployed across multiple product programs under research and development and, as such, are not separately classified. The table below shows our research and development expenses incurred with respect to each active program, in thousands. The primary drivers of our research and development expenditures are currently in our product development programs in CDD, RSE, TSC and ESE. We did not allocate research and development expenses to any other specific product development programs during the periods presented (in thousands):

	Three Months Ended				Six Months Ended

(1) The decrease in the three months ended June 30, 2023 compared to the 2022 period was due primarily to decreased clinical trial activity. Costs for the six months ended June 30, 2023 compared to the 2022 period remained relatively flat as we had increased clinical site close-out activities related to the Marigold trial and increased activity associated with the MAA application and review in the first quarter of 2023, all of which were partially offset by the decrease in clinical trial activity in the three months ended June 30, 2023 compared to the 2022 period.

(2) The decrease in the three and six months ended June 30, 2023 compared to the 2022 period was due to reduced clinical activity, specifically completion of the open label extension portion of the PCDH-19 trial.

(3) The increase in the three and six months ended June 30, 2023 compared to the 2022 period was due primarily to increased Phase 3 TSC trial activity, including increased global site activity and an investigator meeting, as compared to more limited Phase 3 activity in the 2022 period.

(4) The increase in the three months ended June 30, 2023 compared to the 2022 period was due primarily to higher manufacturing development activity related to clinical trial batches than in the prior 2022 period. The decrease in the six months ended June 30, 2023 compared to the 2022 period was due primarily to higher manufacturing development activity related to pre-validation and registration batches in the 2022 period, partially offset by the higher manufacturing development activity related to clinical trial batches in the three months ended June 30, 2023.

42

(5) The increase in the three and six months ended June 30, 2023 compared to the 2022 period was due primarily to increased RAISE and RAISE II Phase 3 trial activity.

(6) The decrease in the three months ended June 30, 2023 compared to the 2022 period was primarily due to set-up fees at a new third party manufacturer in the 2022 period. The increase in the six months ended June 30, 2023 compared to the 2022 period was due primarily to start-up costs associated with validation of a new third-party supplier of ganaxolone API with no comparable costs in the prior 2022 period.

(7) Other research and development expenses include external expenses associated with preclinical development of ganaxolone, including safety studies, stability studies, preclinical studies, including animal toxicology and pharmacology studies, and other professional fees. The decrease in the three and six months ended June 30, 2023 compared to the 2022 period was due primarily to decreased activities associated with the Phase 1 clinical trials.

(8) The increase in the three and six months ended June 30, 2023 compared to the 2022 period was primarily related to increased personnel costs in support of our increased activity in preclinical, clinical, and manufacturing activities.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were $15.7 million and $30.9 million for the three and six months ended June 30, 2023, respectively, compared to $17.1 million and $28.8 million for the three and six months ended June 30, 2022, respectively. The primary drivers of the decrease for the three months ended June 30, 2023 compared to 2022 were $1.7 million in decreased commercial costs, primarily as a result of significant commercial-launch preparedness activities in 2022 and net other cost decreases of $0.2 million. These decreases were partially offset by $0.5 million in increased employee and personnel costs. The primary drivers of the increase for the six months ended June 30, 2023 compared to 2022 were $2.9 million in increased employee and personnel costs, $1.1 million in increased general costs including professional fees; and net other cost increases of $0.8 million. These increases were partially offset by $2.7 million in decreased commercial costs, primarily due to significant commercial-launch preparedness activities in 2022.

Interest Income

Interest income was $2.1 million and $4.5 million for the three and six months ended June 30, 2023, respectively, compared to less than $0.1 million for the three and six months ended June 30, 2022, respectively. The increase is due to the increase in cash, cash equivalent and short-term investments and increased yield.

Interest Expense

Interest expense was $4.2 million and $8.4 million for the three and six months ended June 30, 2023, respectively, compared to $2.7 million and $4.3 million for the three and six months ended June 30, 2022, respectively. Interest expense for the six months ended June 30, 2023 included $4.3 million of interest paid and $1.0 million of debt amortization in connection with our Note Payable (Note 10 in accompanying notes to consolidated financial statements), and $2.9 million of non-cash interest expense and $0.1 million of debt amortization related to our revenue interest financing payable (Note 11 in accompanying notes to consolidated financial statements). Interest expense for the six months ended June 30, 2022 included $3.5 million of interest paid, $0.7 million of debt amortization, and $0.1 million related to commitment fees paid in connection with our Note payable.

Other Income (Expense), net

Other income was not material for the three and six months ended June 30, 2023. Other expense was $1.1 million for the six months ended June 30, 2022, which consisted principally of foreign currency transaction losses, losses on fixed assets held for sale, and fair value adjustments. Other expense was not material for the three months ended June 30, 2022.

43

Liquidity and Capital Resources

Since inception, other than for the three months ended September 30, 2022 due to a one-time net gain from the sale of our PRV, we have incurred net losses and negative cash flows from our operations. We incurred a net loss of $66.7 million and $58.8 million for the six months ended June 30, 2023 and 2022, respectively. Our cash used in operating activities was $65.8 million for the six months ended June 30, 2023 compared to $61.3 million for the six months ended June 30, 2022. Historically, we have financed our operations principally through the sale of common stock, notes payable, preferred stock and convertible debt.

In July 2022, we entered into the PRV Asset Purchase Agreement to sell our PRV, pursuant to which Novo Nordisk, Inc. paid us $110.0 million upon the closing of the transaction. In August 2022, we received a letter from Purdue in which Purdue claimed that it was owed $5.5 million by us from the sale of the PRV pursuant to the Purdue License Agreement. Our position communicated to Purdue is that we do not owe Purdue any of the proceeds from the sale of the PRV. No associated payment by us has been made, and Purdue has not filed a specific claim to date.

In November 2022, in connection with an underwritten public offering of 10,526,316 shares of our common stock, pre-funded warrants to purchase 2,105,264 shares of common stock and the exercise of an option of 1,894,737 shares of common stock, we received approximately $64.5 million in total net proceeds after taking into account the exercise of the underwriters’ option, in each case deducting the underwriting discounts and commissions and after deducting offering expenses paid or payable by us. Additionally, in November 2022, we received an upfront payment of $32.5 million pursuant to the Revenue Interest Financing Agreement with Sagard, and in December 2022, we received an upfront payment of $10.0 million in connection with the Tenacia Collaboration Agreement.

As of June 30, 2023, we had cash, cash equivalents and short-term investments of $175.3 million. We believe that our existing cash, cash equivalents and short-term investments as of June 30, 2023 will be sufficient to fund our operating expenses and capital expenditure requirements, as well as maintain the minimum cash balance required under our debt facility, into the second half of 2024. However, we will need to secure additional funding in the future, from one or more equity or debt financings, government funding, collaborations, licensing transactions, other commercial transactions or other sources in order to carry out all of our commercialization and planned research and development activities with respect to ganaxolone.

Orion Commercialization Agreement

On July 30, 2021, we entered into the Orion Collaboration Agreement, whereby Orion received exclusive rights to commercialize the oral and IV dose formulations of ganaxolone in the European Economic Area, United Kingdom and Switzerland (collectively, Territory) in multiple seizure disorders, including CDD, TSC and RSE. Under the agreement, we received a €25 million ($29.6 million) upfront fee. We are eligible to receive up to an additional €97 million in research and development reimbursement and cash milestone payments based on specific clinical and commercial achievements, as well as tiered royalty payments based on net sales ranging from the low double-digits to high teens for the oral programs and the low double-digits to low 20s for the IV program. As a result of the July 2023 EC approval of ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age, we are now eligible under the Orion Collaboration Agreement to receive a commercial milestone payment of 10 million Euro, if commercial sales of ZTALMY commence in the Territory, upon the earlier of (1) the first commercial sale of ZTALMY within two of a select set of countries consisting of Germany, France, Italy, Spain, and the United Kingdom or (2) the 18-month anniversary of the first commercial sale of ZTALMY in the Territory. Also, as part of the overall arrangement, we have agreed to supply the Licensed Products to Orion at an agreed upon price.

Tenacia Commercialization Agreement

On November 16, 2022, we entered into a collaboration and supply agreement with Tenacia Biotechnology (Shanghai) Co., Ltd. (Tenacia), pursuant to which we granted Tenacia an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights to develop, commercialize and otherwise exploit certain products incorporating certain oral and intravenous formulations of our product candidate ganaxolone (Licensed Products) in Mainland China, Hong Kong, Macau and Taiwan (collectively, Territory) for the diagnosis, prevention and treatment of

44

certain human diseases, disorders or conditions (Field), initially for the treatment of cyclin-dependent kinase-like 5 deficiency disorder, tuberous sclerosis complex and SE (including refractory and established SE) (collectively, Initial Indications). The collaboration can be expanded to include additional indications and formulations of ganaxolone pursuant to a right of first negotiation.

In connection with the execution of the Tenacia Collaboration Agreement, Tenacia agreed to pay us an upfront cash payment of $10 million (Upfront Fee) within forty-five (45) days after the Effective Date and payment was received in December 2022. In addition to the Upfront Fee, Tenacia has agreed to make cash payments to us upon the achievement of certain development, regulatory and sales-based milestones related to (i) the Initial Indications and (ii) the first new formulation or pro-drug of ganaxolone or any back-up compound of ganaxolone in a new indication (Selected Product) for which the parties amend the Tenacia Collaboration Agreement in connection with Tenacia’s exercise of its right of first negotiation and for which there is no other Licensed Product approved in China (for clarity, the milestone payments under this clause (ii) will only apply to one Selected Product), up to an aggregate amount of $256 million. Of the milestones, $15 million relates to regulatory approvals with separate milestones related to each of oral and intravenous formulations and the Selected Product, and an aggregate of $241 million of sales-based milestones are connected to annual revenue thresholds specific to each of the oral, intravenous and Selected Product formulations of ganaxolone.

Tenacia has further agreed to pay us tiered royalty payments based on annual net sales of Licensed Products ranging from the low double digits to the mid-teens for each of the oral formulation, intravenous formulation and Selected Product formulation of Licensed Products. Tenacia’s obligations to pay royalties to us with respect to sales of a Licensed Product in each particular jurisdiction of the Territory will commence on the date of first commercial sale in such jurisdiction and expire upon the latest of (i) ten years following the first commercial sale of such Licensed Product in such jurisdiction, (ii) the expiration of the last-to-expire valid claim of any licensed patent rights that covers such Licensed Product in such jurisdiction and (iii) the expiration of all regulatory exclusivities for such Licensed Product in such jurisdiction. Royalty payments are subject to reduction in specified circumstances as set forth in the Tenacia Collaboration Agreement, including if net sales decrease by a certain percentage after the introduction of a generic product.

Biologix Distribution and Supply Agreement

In May 2023, we entered into an exclusive distribution and supply agreement (Biologix Agreement) with Biologix FZCo (Biologix), whereby Biologix has the right to distribute and sell ganaxolone in Algeria, Bahrain, Egypt, Iraq, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Tunisia and United Arab Emirates. In exchange for distribution rights, we will be the exclusive supplier of our products to Biologix on terms set forth in the Biologix Agreement in exchange for a negotiated purchase price for the products. Upon execution of the Biologix Agreement, we received an upfront payment of $0.5 million which is to be amortized over the term of the agreement. We may be entitled to additional fees upon regulatory milestones. In the six months ended June 30, 2023, we recorded less than $0.1 million of collaboration revenue related to the Biologix Agreement.

NovaMedica Agreement

In June 2013, we entered into a clinical development and collaboration agreement with NovaMedica LLC (NovaMedica) for commercialization of ganaxolone, and in December 2022, as amended in May 2023, we entered into a manufacturing and supply agreement with NovaMedica, whereby NovaMedica has the right to market and sell ganaxolone in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan. In exchange for distribution rights, we will be the exclusive supplier of our products to NovaMedica on terms set forth in the NovaMedica Agreement in exchange for a negotiated purchase price for the products. As of the first quarter of 2023, we have initiated limited sales of ZTALMY to NovaMedica to support on-going early access programs associated with patients from the Marigold trial.

Oaktree Credit Agreement

On May 11, 2021 (Closing Date) and as amended on May 17, 2021, May 23, 2022 and October 28, 2022 (Credit Agreement), we entered into the Credit Agreement with Oaktree Fund Administration, LLC as administrative agent (Oaktree) and the lenders party thereto (collectively, Lenders) that provides for a five-year senior secured term loan facility in an aggregate original principal amount of up to $100.0 million, available to us in four tranches (collectively, Term Loans). As of June 30, 2023, we had drawn on three tranches, and the following tranche remained available to us:

● Through December 31, 2023, $25.0 million of Tranche C Term Loans will be available for draw if we complete one or more financings (including through the issuance of common stock, convertible debt, subordinated debt, a synthetic royalty or a sublicense) resulting in gross proceeds to us of at least $40.0 million and net proceeds to us of at least $36.0 million (Qualified Financing Condition). However, the availability of this tranche is also subject to either our current Phase 3 trial in RSE or a Phase 3 trial in TSC achieving statistical significance (p value < 0.05) across all primary endpoints and ganaxolone must be generally well tolerated, with a safety profile generally consistent with previous clinical trials. We do not currently anticipate data from either Phase 3 trial prior to December 31, 2023.

We received $15.0 million of Tranche A-1 Term Loans on the Closing Date, $30.0 million of Tranche A-2 Term Loans in September 2021 after formal acceptance by the FDA of an NDA filing relating to the use of ganaxolone in the treatment of CDD, and $30.0 million of Tranche B Term Loans in March 2022 after FDA approval of ZTALMY for CDD. We satisfied the Qualified Financing Condition in connection with our November 2022 underwritten public offering, however, if we are unable to satisfy the remaining condition, we would not be able to draw down the remaining tranche of loans and may not be able to obtain alternative financing on commercially reasonable terms or at all.

The Term Loans mature on May 11, 2026 (Maturity Date). The Term Loans bear interest at a fixed per annum rate (subject to increase during an event of default) of 11.50%, and we are required to make quarterly interest payments until the Maturity Date. We are also required to make quarterly principal payments beginning on June 30, 2024 in an amount equal to 5.0% of the aggregate amount of the Term Loans outstanding on June 30, 2024, and continuing until the Maturity Date. On the Maturity Date, we are required to pay in full all outstanding Term Loans and other amounts owed under the Credit Agreement.

At the time of borrowing any tranche of the Term Loans, we are required to pay an upfront fee of 2.0% of the aggregate principal amount borrowed at that time.

In connection with the Revenue Interest Financing Agreement, on October 28, 2022, we entered into an amendment to the Credit Agreement to, among other things, allow for the consummation of the Revenue Interest Financing Agreement and the transactions thereunder, and paid $0.3 million in administrative fees in connection with the execution of the amendment. In addition, the amendment increased the exit fee due by us upon any repayment, whether as a prepayment or a scheduled repayment, of the principal of the loans under the Credit Agreement from 2.00% to 2.67%.

Sagard Financing Agreement

In October 2022, we entered into a revenue interest financing agreement (the Revenue Interest Financing Agreement) with Sagard Healthcare Royalty Partners, LP (Sagard) pursuant to which we received $32.5 million.

In  exchange for the Investment Amount, we have agreed to make quarterly payments to Sagard (Payments) as follows: (i) for each calendar quarter from and after the closing date of such financing through and including the quarter ended June 30, 2026, an amount equal to 7.5% of (a) our U.S. net sales of ZTALMY and all other pharmaceutical products that contain ganaxolone (Net Sales), in each case with any dosage form, dosing regimen, or strength, or any improvements related thereto (collectively, Included Products) and (b) certain other payments received by us in connection with the manufacture, development and sale of the Included Products in the U.S. (Other Included Payments,

46

and, together with Net Sales, Product Revenue); and (ii) for each calendar quarter following the calendar quarter ended June 30, 2026, an amount equal to (x) 15.0% of the first $100 million in annual Product Revenue of the Included Products and (y) 7.5% of annual Product Revenue of the Included Products in excess of $100 million.

The Payments are subject to a hard cap equal to 190% ($61.8 million) of the Investment Amount (Hard Cap). Sagard’s right to receive payments will terminate when Sagard has received payments in respect of the Included Products, including any additional payments described below, equal to the Hard Cap. Further, we have the right to make voluntary prepayments to Sagard, and such payments will be credited against the Hard Cap.

If Sagard has not received aggregate payments equaling at least 100% of the Investment Amount by December 31, 2027 or at least 190% of the Investment Amount by December 31, 2032 (each, Minimum Amount), then we will be obligated to make a cash payment to Sagard in an amount sufficient to gross up Sagard up to the applicable Minimum Amount within a specified period of time after each reference date.

BARDA Contract

In September 2020, we and BARDA entered into the BARDA Contract, under which we received an award of up to an estimated $51 million for development of IV-administered ganaxolone for the treatment of RSE. The BARDA Contract provides for funding to support, on a cost-sharing basis, the completion of a Phase 3 clinical trial of IV-administered ganaxolone in patients with RSE, which covers the RAISE trial, funding of pre-clinical studies to evaluate IV-administered ganaxolone as an effective treatment for RSE due to chemical nerve gas agent exposure, and funding of certain ganaxolone manufacturing scale-up and regulatory activities. In March 2022, we entered into an amendment with BARDA to extend the end date of our base performance period for funding under the BARDA Contract from September 1, 2022 to December 31, 2023. In September 2022, we entered into an amendment with BARDA that, among other things, (i) provides for the exercise of BARDA’s option under the BARDA Contract to support U.S. onshoring of the manufacturing capabilities for ganaxolone API (Option 2), (ii) changes the end of date of our performance period under Option 2 from December 31, 2026 to July 31, 2025, (iii) increases the government cost share amount under Option 2 from approximately $11.5 million to approximately $12.3 million, and (iv) increases our cost share amount under Option 2 from approximately $4.9 million to approximately $5.3 million.

The BARDA Contract consists of an approximately two-year base period, and an extension period through December 31, 2023, during which BARDA will provide up to approximately $21 million of funding for the RAISE trial on a cost share basis and funding of additional preclinical studies of ganaxolone in nerve agent exposure models. Following successful completion of the RAISE trial and preclinical studies in the base period and extension period, the BARDA Contract provides for approximately $31 million of additional BARDA funding for three options in support of ganaxolone manufacturing, supply chain, clinical, regulatory and toxicology activities, including the $12.3 million exercise of Option 2 as described above. Under the BARDA Contract, we will be responsible for cost sharing in the amount of approximately $33 million and BARDA will be responsible for approximately $52 million if all development options are completed. The contract period-of-performance (base period plus option exercises) is up to approximately five years.

Equity Financings

In connection with the closing of an equity financing in November 2022 and the December 2022 exercise of the related underwriters’ option, we issued a total of 12,421,053 shares of common stock and 2,105,264 pre-funded warrants

47

to purchase common stock in an underwritten public offering resulting in aggregate net proceeds of $64.5 million, after deducting the underwriting discounts and commissions and offering expenses paid or payable by us.

Equity Distribution Agreement

On July 9, 2020, we entered into an Equity Distribution Agreement (as subsequently amended on March 31, 2023, the EDA) with JMP Securities LLC (JMP) to create an at the market equity program under which we from time to time may offer and sell shares of our common stock without a maximum aggregate offering price through JMP, acting as agent and/or principal. Subject to the terms and conditions of the EDA, JMP will be entitled to a commission of up to 3.0% of the gross proceeds from each sale of shares of our common stock. We did not sell any shares of our common stock during the three and six months ended June 30, 2023 and 2022 under the EDA.

IP License Agreement

In March 2022, we entered into the License Agreement with Ovid. Under the License Agreement, we have an exclusive, non-transferable (except as provided in the License Agreement), royalty-bearing, sublicensable license under certain of Ovid’s patent(s) and patent applications to develop, make, have made, commercialize, promote, distribute, sell, offer for sale and import, ganaxolone, including any analogues or derivatives, including its salts, and pharmaceutical formulations of the foregoing (Licensed Products), in the U.S., the member states of the EU, Iceland, Lichtenstein, Norway, the United Kingdom, and Switzerland (Territory) for the treatment of CDD in humans (Field). Under the License Agreement, we have the sole right and responsibility for, and control over, all development, manufacturing, and commercialization activities, including all regulatory activities, with respect to the Licensed Products in the Field in the Territory. In addition, all regulatory approvals and related filings with respect to the Licensed Products in the Field in the Territory will be in the name of, and be owned solely by, us. We were required, at Ovid’s option exercisable in accordance with the License Agreement, to (i) pay to Ovid the sum of $1.5 million in cash; or (ii) issue to Ovid 123,255 shares of our common stock, which option to obtain shares of our common stock was exercisable within the five-business day period following the filing of our Annual Report on Form 10-K for the year ended December 31, 2021 on March 24, 2022. On March 29, 2022, we issued 123,255 shares of our common stock to Ovid, per Ovid’s option in accordance with the License Agreement. As such, we recorded $1.2 million of IP license fee expenses related to the Ovid License Agreement in the six months ended June 30, 2022.

The License Agreement also provides for payment of royalties by us to Ovid in the low single digits on net sales by us, our affiliates and sublicensees, of Licensed Products in the Field in the Territory. Such royalties are subject to reduction in the event of generic competition in accordance with the License Agreement. We may terminate the License Agreement at any time without cause on thirty days’ prior written notice. Either party may terminate the License Agreement for the other party’s material breach or insolvency subject to certain cure periods. Also, Ovid has the right to terminate the License Agreement if there has not been a first commercial sale of any Licensed Products in the Field in the Territory on or before June 30, 2025. In the event of termination, all licenses granted under the License Agreement will terminate.

Cash Flows

Operating Activities. Cash used in operating activities increased to $65.8 million for the six months ended June 30, 2023 compared to $61.3 million for the same period in 2022. Excluding the noncash impacts primarily related to depreciation and amortization, debt issuance costs, accretion of revenue interest financing and amortization of discounts on short-term investments, stock-based compensation, cost of license agreement and changes in the net contract assets/liabilities related to the Orion, Tenacia and Biologix collaboration agreements, the change in cash used in operating activities for the six months ended June 30, 2023 compared to the same period in 2022, was primarily the result of decreases in the changes in accounts payable, accrued expenses, other long term-liabilities, prepaid expenses, other current assets, inventory and accounts receivable and an increase in operating expenses.

Investing Activities. Cash used in investing activities for the six months ended June 30, 2023 represents $52.0 million in purchases of short-term investments partially offset by $5.0 million in maturities of short-term investments.

48

Cash used in investing activities for the three months ended June 30, 2022 represents $0.4 million in purchases of property and equipment.

Financing Activities. Cash provided by financing activities for the six months ended June 30, 2023 represents $0.5 million in proceeds from the exercise of stock options, partially offset by $0.4 million of payments in connection with the Revenue Interest Financing Agreement with Sagard. Cash provided by financing activities for the six months ended June 30, 2022 includes $29.4 million in proceeds from notes payable, net of issuance costs, and $1.7 million in proceeds from the exercise of stock options.

Funding Requirements

Since inception, other than for the three months ended September 30, 2022 due to a one-time net gain from the sale of our PRV, we have incurred net losses and negative cash flows from our operations. We incurred a net loss of $66.7 million for the six months ended June 30, 2023. We have generated limited product revenues, and there is no assurance that profitable operations will be achieved in the future, and if achieved, could be sustained on a continuing basis.

We had cash, cash equivalents and short-term investments of $175.3 as of June 30, 2023. We believe that our existing cash, cash equivalents and short-term investments as of June 30, 2023 will be sufficient to fund our operating expenses and capital expenditure requirements, as well as maintain the minimum cash balance required under our debt facility, into the second half of 2024. However, we will need to secure additional funding in the future, from one or more equity or debt financings, government funding, collaborations, licensing transactions, other commercial transactions or other sources in order to carry out all of our commercialization and planned research and development activities with respect to ganaxolone. In order to meet these additional cash requirements, we may seek to sell additional equity or convertible debt securities that may result in dilution to our stockholders, or engage in federal contracts or other partnerships. If we raise additional funds through the issuance of convertible debt securities, these securities could have rights senior to those of our common stock and could contain covenants that restrict our operations. There can be no assurance that we will be able to obtain additional equity or debt financing on terms acceptable to us, if at all. Further, the continued spread of COVID-19 has also led to severe disruption and volatility in the global capital markets, which could increase our cost of capital and adversely affect our ability to access the capital markets in the future. Our failure to obtain sufficient funds on acceptable terms when needed could have a negative impact on our business, results of operations, and financial condition.

Our future capital requirements will depend on many factors, including:

● the effects of the COVID-19 pandemic on our business, the medical community and the global economy;

● the results of our preclinical studies and clinical trials;

● the development, formulation and commercialization activities related to ganaxolone, including ZTALMY;

● the scope, progress, results and costs of researching and developing ganaxolone, including ZTALMY, or any other future product candidates, and conducting preclinical studies and clinical trials;

● the timing of, and the costs involved in, obtaining regulatory approvals for ganaxolone, including ZTALMY, or any other future product candidates;

● the cost of commercialization activities for ZTALMY in CDD in the U.S., including marketing, sales and distribution costs;

● the cost of commercialization activities for ZTALMY, ganaxolone in any other indications, or any other future product candidates, are approved for sale, including marketing, sales and distribution costs;

49

● the cost of manufacturing and formulating ganaxolone, or any other future product candidates, to internal and regulatory standards for use in preclinical studies, clinical trials and, if approved, commercial sale;

● our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such agreements;

● our ability to receive funding under the BARDA Contract;

● our expectations regarding the amount and timing of milestone and royalty payments pursuant to our exclusive license agreements with Orion and Tenacia.

● any product liability, infringement or other lawsuits related to ZTALMY or other indications being developed for ganaxolone and, if approved, products;

● capital needed to attract and retain skilled personnel;

● the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome of such litigation; and

● the timing, receipt and amount of sales of, or royalties on, ZTALMY in CDD and on future approved products, if any.

Please see the Risk Factors section included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 9, 2023 for additional risks associated with our substantial capital requirements.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Discussion of Critical Accounting Policies and Significant Judgments and Estimates

The preparation of financial statements in conformity with GAAP requires us to use judgment in making certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses in our financial statements and accompanying notes. Critical accounting policies are those that are most important to the portrayal of our financial condition and results of operations and require difficult, subjective and complex judgments by management in order to make estimates about the effect of matters that are inherently uncertain. During the three months ended June 30, 2023, there were no significant changes to our critical accounting policies from those described in our annual financial statements for the year ended December 31, 2022, which we included in our Annual Report on Form 10-K and was filed with the SEC on March 9, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended (Exchange Act) and are not required to provide the information under this item.

50

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2023.

(b) Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended June 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

51

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may become subject to litigation and claims arising in the ordinary course of business. We are not currently a party to any material legal proceedings, and we are not aware of any pending or threatened legal proceedings against us that we believe could have a material adverse effect on our business, operating results or financial condition.

Item 1A. Risk Factors

Except as set forth below, there have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Third parties, such as Ovid Therapeutics, Inc., may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could harm our business.

Our commercial success depends upon our ability to develop, manufacture, market and sell our products and product candidates, all of which contain ganaxolone and to use our related technologies. We may become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to one or more of our products, including interference or derivation proceedings before the U.S. Patent and Trademark Office (USPTO). Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future. If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue commercializing one or more of our products. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Under certain circumstances, we could be forced, including by court order, to cease commercializing one or more of our products. In addition, in any such proceeding or litigation, we could be found liable for monetary damages. A finding of infringement could prevent us from commercializing one or more of our products or force us to cease some of our business operations, which could materially harm our business. Any claims by third parties that we have misappropriated their confidential information or trade secrets could have a similar negative impact on our business.

While our product candidates are in preclinical studies and clinical trials, we believe that the use of our product candidates in these preclinical studies and clinical trials falls within the scope of the exemptions provided by 35 U.S.C. Section 271(e) in the U.S., which exempts from patent infringement liability activities reasonably related to the development and submission of information to the FDA (Federal Development Patent Infringement Exemption). As our product candidates progress toward commercialization, the possibility of a patent infringement claim against us increases. While ganaxolone itself is off patent, we attempt to ensure that our product candidates and the methods we employ to manufacture ganaxolone do not infringe other parties’ patents and other proprietary rights. There can be no assurance they do not, however, and competitors or other parties may assert that we infringe their proprietary rights in any event.

On July 26, 2022, the USPTO issued U.S. Patent No. 11,395,817 to Ovid Therapeutics, Inc. (Ovid) with claims that encompass our product candidate for the treatment of SE. On March 15, 2023, we filed a petition seeking post-grant review (PGR) of Ovid’s U.S. Patent No. 11,395,817 with the U.S. Patent and Trademark Office Patent Trial and Appeal Board (the PTAB). Our petition for PGR argues that the claims of U.S. Patent No. 11,395,817 are unpatentable on multiple grounds. Ovid filed a preliminary response to our petition on June 20, 2023, and the PTAB has until September 20, 2023 to decide whether to grant our petition and institute the PGR. If the PGR is instituted and we do not prevail, the decision can be appealed to the Court of Appeals for the Federal Circuit. If an appeal is not successful, our ability to challenge the validity of Ovid’s U.S. Patent No. 11,395,817 in court would be limited, or we may not be able challenge the validity of the patent in court at all.

Ovid may file a lawsuit against us alleging infringement of its patents. Any such proceeding, in the PTAB or courts, regardless of their outcome, would likely result in the expenditure of significant financial resources and the

52

diversion of management’s time and resources. In addition, any such proceeding may cause negative publicity, adversely impact patients, and we may be prohibited from marketing or selling ganaxolone for SE, RSE and ESE during such proceedings or if we are not successful in such proceedings. If Ovid does decide to bring an infringement lawsuit, we do not expect that it will be filed before a commercial launch of ganaxolone for SE, RSE or ESE based upon the “safe harbor” provisions of the Hatch-Waxman Act. We may need to acquire or obtain a license to the Ovid patents to market or sell ganaxolone for SE, RSE or ESE, which may not be available on commercially acceptable terms or at all. If we are not able to acquire the Ovid patents or negotiate a license on acceptable terms, and if our product is determined to infringe Ovid’s patents and the patents are determined to be valid, then we may be forced to pay Ovid royalties, damages and costs, or we may be prevented from commercializing ganaxolone for SE, RSE and ESE altogether, which would have a material adverse impact on our business.

MARINUS PHARMACEUTICALS, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of the Business and Liquidity

We are a commercial-stage pharmaceutical company dedicated to the development of innovative therapeutics for the treatment of seizure disorders, including rare genetic epilepsies and status epilepticus. On March 18, 2022, the U.S. Food and Drug Administration (FDA) approved our new drug application (NDA) for the use of ZTALMY (ganaxolone) oral suspension for the treatment of seizures associated with Cyclin-dependent Kinase-like 5 (CDKL5) Deficiency Disorder (CDD) in patients 2 years of age and older. In June 2022, the U.S. Drug Enforcement Administration (DEA) published an interim final rule in the Federal Register placing ganaxolone and its salts in schedule V (CV) of the Controlled Substances Act (CSA), which rule became final on December 9, 2022. ZTALMY, our first FDA approved product, became available for commercial sale and shipment in the third quarter of 2022. On July 28, 2023, the European Commission (EC) granted marketing authorization for ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age. ZTALMY may be continued in patients 18 years of age and older. With the EC marketing authorization granted for ZTALMY, Orion Corporation (Orion), our commercialization partner for ZTALMY in Europe, has announced it has begun preparations for the launch of ZTALMY, including engaging in the required processes for obtaining pricing and reimbursement approval in the various European countries. The pricing and reimbursement process can be time consuming and may delay Orion’s commercial launch of ZTALMY in one or more European countries. We are developing ganaxolone for the treatment of other rare genetic epilepsies, including Tuberous Sclerosis Complex (TSC), and for the treatment of status epilepticus (SE). We are developing ganaxolone in formulations for two different routes of administration: intravenous (IV) and oral. The different formulations are intended to maximize potential therapeutic applications of ganaxolone for adult and pediatric patient populations, in both acute and chronic care, and for both acute in-hospital care and chronic at home-administration settings. While the precise mechanism by which ganaxolone exerts its therapeutic effects in the treatment of seizures is unknown, its anticonvulsant effects are thought to result from positive allosteric modulation of the gamma-aminobutyric acid type A (GABA_A) receptor in the central nervous system (CNS). Ganaxolone is a synthetic analog of allopregnanolone, an endogenous neurosteroid. Ganaxolone acts at both synaptic and extrasynaptic GABA_A receptors, a target known for its anti-seizure, antidepressant and anxiolytic potential.

COVID-19 affected our clinical operations and timelines. For example, our RAISE trial for refractory SE (RSE) is conducted in hospitals, primarily intensive care units in academic medical centers, which experienced high rates of COVID-19 admissions. Several of these sites participating in the RAISE trial experienced COVID-related difficulties, including staff turnover and the need to devote significant resources to patients with COVID-19, which resulted in site initiation and enrollment delays for the RAISE trial. Given these COVID-19-related challenges and the interruption in drug supply in mid-2022, we previously adjusted our expectation for our top-line data readout for the RAISE trial. In May 2022, we resumed screening and recruitment for the RAISE trial. We now expect our interim analysis with top-line data readout for the RAISE trial to be available in the first quarter of 2024.

Since inception, other than for the three months ended September 30, 2022 due to a one-time net gain from the sale of our Priority Review Voucher (PRV), we have incurred net losses and negative cash flows from our operations. We incurred a net loss of $66.7 million for the six months ended June 30, 2023. There is no assurance that profitable operations will be achieved in the future, and if achieved, could be sustained on a continuing basis. In addition, development activities, clinical and preclinical testing, and commercialization of ganaxolone (in indications other than CDD in the U.S.) will require significant additional financing. Our accumulated deficit as of June 30, 2023 was $497.2 million, and we expect to incur substantial losses in future periods. We plan to finance our future operations with a combination of proceeds from the issuance of equity securities, the issuance of debt, government funding, collaborations, licensing transactions and other commercial transactions or other sources, and revenues from product sales. We have not generated positive cash flows from operations, and there are no assurances that we will be successful in obtaining an adequate level of financing for the continued development and commercialization of ganaxolone.

Management’s operating plan, which underlies the analysis of our ability to continue as a going concern, involves the estimation of the amount and timing of future cash inflows and outflows. Actual results could vary from the operating plan. We follow the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 205-40, Presentation of Financial Statements—Going Concern, which requires management to assess our ability to continue as a going concern within one year after the date the financial statements are issued. We believe that our existing cash, cash equivalents and short-term investments as of June 30, 2023, will be sufficient to fund our operating expenses and capital expenditure requirements, as well as maintain the minimum cash balance required under our debt facility, for the one-year period after the date the financial statements are issued. However, we will need to secure additional funding in the future, from one or more equity or debt financings, government funding, collaborations, licensing transactions, other commercial transactions or other sources in order to carry out all of our commercialization and planned research and development activities with respect to ganaxolone.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of Marinus Pharmaceuticals, Inc. (a Delaware corporation) as well as the accounts of Marinus Pharmaceuticals Emerald Limited (an Ireland company incorporated in February 2021), a wholly owned subsidiary requiring consolidation. Marinus Pharmaceuticals Emerald Limited serves as a corporate presence in the European Union for regulatory purposes. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all information and disclosures necessary for a presentation of our financial position, results of operations and cash flows in conformity with generally accepted accounting principles in the U.S. (GAAP) for annual financial statements. In the opinion of management, these unaudited interim consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of our financial position and results of operations and cash flows for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for the full year. These unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2022 and accompanying notes thereto included in our Annual Report on Form 10-K filed with the SEC on March 9, 2023.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from such estimates.

Product Revenue, net

We recognize ZTALMY revenue in accordance with ASC 606 – Revenue from contracts with customers. Our revenue recognition analysis consists of the following steps: (i) identification of the promised goods in the contract; (ii) determination of whether the promised goods are performance obligations, including whether they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

Our first FDA approved product, ZTALMY, became available for commercial sale and shipment in the third quarter of 2022. We have three customers, one of which, Orsini Pharmaceutical Services, LLC (Orsini), a specialty pharmacy that dispenses ZTALMY directly to patients, represents over 99% of our ZTALMY revenue to date. Our contract with Orsini has a single performance obligation to deliver ZTALMY upon receipt of a purchase order, which is satisfied when Orsini receives ZTALMY. We recognize ZTALMY revenue at the point in time when control of ZTALMY is transferred to Orsini, which is upon delivery to Orsini. The transaction price that we recognize for

ZTALMY revenue includes an estimate of variable consideration. Shipping and handling costs to Orsini are recorded as selling, general and administrative expenses. The components of variable consideration include:

Trade Discounts and Allowances. We provide an incentive prompt payment discount to Orsini as explicitly stated in the contract with Orsini. This discount is recorded as a reduction of ZTALMY revenue and accounts receivable in the period in which the related ZTALMY revenue is recognized. We estimate the amount of variable consideration for all discounts and allowances using the expected value method.

Product Returns and Recall. We provide for ZTALMY returns in accordance with our Return Good Policy. We estimate the amount of ZTALMY that may be returned using the expected value method, and we present this amount as a reduction of ZTALMY revenue in the period the related ZTALMY revenue is recognized. In the event of a recall, we will promptly notify Orsini and will reimburse Orsini for direct administrative expenses incurred in connection with the recall as well as the cost of replacement product.

Government Rebates. We are subject to discount obligations under state Medicaid programs, Medicare, and the Tricare Retail Refund Program. We estimate reserves related to these discount programs and record these obligations in the same period the related revenue is recognized, resulting in a reduction of product revenue.

Patient Assistance. We offer a voluntary co-pay patient assistance program intended to provide financial assistance to eligible patients with a prescription drug co-payment required by payors and coupon programs for cash payors. The calculation of the current liability for this assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with ZTALMY that has been recognized as revenue but remains in the distribution channel inventories at the end of each reporting period.

Federal Contract Revenue

We recognize federal contract revenue from the BARDA Contract in the period in which the allowable research and development expenses are incurred, and receivables associated with this revenue are included within accounts receivable on our interim consolidated balance sheets. This revenue is not within the scope of ASC 606 – Revenue from contracts with customers.

Short-term Investments

We classify our short-term investments as available-for-sale securities, which include U.S. government agency debt securities and U.S. treasury debt securities with original maturities of greater than three months. These securities are carried at fair market value, with unrealized gains and losses reported in comprehensive loss and accumulated other comprehensive income within stockholders’ equity. All of our investments were short-term in nature as of June 30, 2023.

Accounts Receivable, net

Net trade receivables related to ZTALMY sales, which are recorded in net accounts receivable on the consolidated balance sheets, were approximately $1.8 million and $1.3 million as of June 30, 2023 and December 31, 2022, respectively. As of both June 30, 2023 and December 31, 2022, we had no allowance for doubtful accounts. An allowance for doubtful accounts is determined based on our assessment of the creditworthiness and financial condition of our customers, aging of receivables, as well as the general economic environment. Any allowance would reduce the net receivables to the amount that is expected to be collected. Payment terms for Orsini are approximately 30 days from the shipment date.

Excluding net trade receivables, accounts receivable represents amounts due to us under the BARDA contract for valid expenditures expected to be reimbursed to us under the terms of the BARDA contract and current amounts due to us from Orion Corporation (Orion) under the collaboration agreement (Note 12).

Inventory

Inventories are recorded using actual costs and may consist of raw materials (ganaxolone API), work in process and finished goods. We began capitalizing inventory related to ZTALMY subsequent to the March 2022 FDA approval of ZTALMY, as the related costs were expected to be recoverable through the commercialization and subsequent sale of ZTALMY. Prior to FDA approval of ZTALMY, costs estimated at approximately $2 million for commercially saleable product and materials were incurred and included in research and development expenses. As a result, cost of product revenues related to ZTALMY will initially reflect a lower average per unit cost of materials into approximately the first half of 2024, as previously expensed inventory is utilized for commercial production and sold to customers.

Debt Issuance Costs

Debt issuance costs incurred in connection with Note payable (Note 10) and revenue interest financing payable (Note 11) are amortized to interest expense over the term of the respective financing arrangement using the effective-interest method. Debt issuance costs, net of related amortization, are deducted from the carrying value of the related debt.

Contract Liabilities, net

When consideration is received, or such consideration is unconditionally due, from a customer prior to completing our performance obligation to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities expected to be recognized as revenue or a reduction of expense within the 12 months following the balance sheet date are classified as current liabilities. Contract liabilities not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as long-term liabilities. In accordance with ASC 210-20, our contract liabilities are partially offset by our contract assets as further discussed in Note 12.

Liability Related to Revenue Interest Financing and Non-Cash Interest Expense

In October 2022, we recognized a liability related to the Revenue Interest Financing Agreement with Sagard Healthcare Royalty Partners, LP (Sagard) under ASC 470-10 Debt and ASC 835-30 Interest - Imputation of Interest. The initial funds we received from Sagard pursuant to the terms of the Revenue Interest Financing Agreement were recorded as a liability and will be accreted under the effective interest method upon the estimated amount of future royalty payments to be made pursuant to the Revenue Interest Financing Agreement. The issuance costs were recorded as a direct deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period the liability will be repaid as further discussed in Note 11. We estimated the total amount of future product revenue to be generated over the life of the Revenue Interest Financing Agreement, and a significant increase or decrease in these estimates could materially impact the liability balance and the related interest expense. If the timing or amounts of any estimated future revenue and related payments change, we will prospectively adjust the effective interest and the related amortization of the liability and related issuance costs.

Collaboration and Licensing Revenue

We may enter into collaboration and licensing arrangements for research and development, manufacturing, and commercialization activities with counterparties for the development and commercialization of our product candidates. These arrangements may contain multiple components, such as (i) licenses, (ii) research and development activities, and (iii) the manufacturing of certain material. Payments pursuant to these arrangements may include non-refundable and refundable payments, payments upon the achievement of significant regulatory, development and commercial milestones, sales of product at certain agreed-upon amounts, and royalties on product sales. The amount of variable consideration is constrained until it is probable that the revenue is not at a significant risk of reversal in a future period.

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under a collaboration agreement, we perform the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether

they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

We must develop estimates and assumptions that require judgment to determine the underlying stand-alone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the stand-alone selling price may include such estimates as forecasted revenues and costs, development timelines, discount rates and probabilities of regulatory and commercial success. We also apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations, allocating transaction price to performance obligations within a contract, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time.

Fair Value Measurements

4. Fair Value Measurements

FASB accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (the exit price) in an orderly transaction between market participants at the measurement date. The accounting guidance outlines a valuation framework and creates a fair value hierarchy in order to increase the consistency and comparability of fair value measurements and the related disclosures. In determining fair value, we use quoted prices and observable inputs. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources.

The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

● Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

● Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

● Level 3 — Valuations based on inputs that are unobservable and models that are significant to the overall fair value measurement.

If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. As of June 30, 2023, all of our financial assets and liabilities were classified as Level 1 or Level 2 valuations. As of December 31, 2022, all of our financial assets and liabilities were classified as Level 1 valuations.

We estimate the fair values of our financial instruments categorized as Level 2 in the fair value hierarchy, including U.S. Treasury securities and U.S. Government Agency securities, by taking into consideration valuations obtained from third-party pricing services. The pricing services use industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, benchmark yields, issuer credit spreads, benchmark securities, and other observable inputs. We obtain a single price for each financial instrument and do not adjust the prices obtained from the pricing service.

The following fair value hierarchy table presents information about each major category of our financial assets and liabilities measured at fair value on a recurring basis (in thousands):

Net Loss Per Share of Common Stock

Net Loss Per Share of Common Stock

7. Net Loss Per Share of Common Stock

Basic net loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted net loss per share of common stock includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred stock, stock options, and unvested restricted stock, which would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are not included in the calculation.

The pre-funded warrants to purchase common stock issued in connection with the November 2022 offering are included in the calculation of basic and diluted net loss per share as the exercise price of $0.001 per share is non-substantive and is virtually assured. The pre-funded warrants are more fully described in Note 8.

The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares of common stock outstanding as they would be anti-dilutive:

	June 30,
	2023	2022
Convertible preferred stock	—	860,000
Restricted stock awards and restricted stock units	1,489,119	758,217

8. Stockholders’ Equity

In 2005, we adopted the 2005 Stock Option and Incentive Plan (2005 Plan) that authorizes us to grant stock options, restricted stock and other equity-based awards. As of June 30, 2023, 577 options to purchase shares of common stock were outstanding pursuant to grants in connection with the 2005 Plan. No additional shares are available for issuance under the 2005 Plan. The amount, terms of grants, and exercisability provisions are determined and set by our board of directors.

Effective August 2014, we adopted our 2014 Equity Incentive Plan, as amended (2014 Plan), that authorizes us to grant stock options, restricted stock, and other equity-based awards, subject to adjustment in accordance with the 2014 Plan. As of June 30, 2023, 5,087,086 options to purchase shares of common stock were outstanding pursuant to grants in connection with the 2014 Plan, and 757,155 shares of common stock were available for future issuance. The amount, terms of grants, and exercisability provisions are determined and set by our board of directors. In accordance with the 2014 Plan, on January 1, 2023, the shares of common stock available for future grants under the 2014 Plan was increased by 2,020,111.

Stock Options

There were 7,220,150 stock options outstanding as of June 30, 2023 at a weighted average exercise price of $9.74 per share, including 2,132,487 stock options outstanding outside of the 2014 Plan, granted as inducements to new employees. During the six months ended June 30, 2023, 1,841,540 options were granted to employees and directors at a weighted average exercise price of $6.20 per share. Of the options granted, 1,532,390 options were granted pursuant to the 2014 Plan and 309,150 were granted outside of the 2014 Plan as inducements for new employees.

Restricted Stock and Restricted Stock Units

All issued and outstanding restricted shares of common stock are time-based, and become vested within two years of the grant date, pursuant to the 2014 Plan. Compensation expense is recorded ratably over the requisite service period. Compensation expense related to restricted stock is measured based on the fair value using the closing market price of our common stock on the date of the grant. As of June 30, 2023, we did not have any restricted shares of common stock outstanding.

During the six months ended June 30, 2023, we granted 959,996 restricted stock units, which vest within three years of the grant date, pursuant to the 2014 Plan. As of June 30, 2023, we had 1,489,119 restricted stock units outstanding.

Total compensation cost recognized for all stock options, restricted stock awards and restricted stock units in the statements of operations is as follows (in thousands):

As of June 30, 2023 all shares of our Series A Convertible Preferred Stock (Preferred Stock) had been converted and none remained outstanding. In the six months ended June 30, 2023, 4,300 shares of our Preferred stock were converted into 860,000 shares of our common stock.

Stock Issued in Connection with Ovid License Agreement

On March 29, 2022, pursuant to an exclusive patent license agreement with Ovid Therapeutics Inc. (Ovid), we issued 123,255 shares of our common stock to Ovid. The shares were issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the Securities Act) provided by Section 4(a)(2) of the Securities Act and Regulation D thereunder as sales by an issuer not involving any public offering (see Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds). The fair value of these shares is reflected in operating expenses for the six months ended June 30, 2022.

Underwritten Public Offering

In connection with an underwritten public offering in November 2022 and the closing of the related exercise of the underwriters’ option in December 2022, we issued a total of 12,421,053 shares of common stock and 2,105,264 pre-funded warrants (the Pre-funded Warrants) resulting in aggregate net proceeds, after underwriting discounts and commissions in the public offering and fees, of $64.5 million. The exercise price and the number of shares of common stock issuable upon exercise of each Pre-funded Warrant (the Warrant Shares) are subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock as well as upon any distribution of assets, including cash, stock or other property, to our stockholders. The Pre-funded Warrants are exercisable at any time, will not expire and are exercisable in cash or by means of a cashless exercise. A holder of Pre-funded Warrants may not exercise such Pre-funded Warrants if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of Pre-funded Warrants may increase or decrease this percentage not in excess of 19.99% by providing at least 61 days’ prior notice to us.

9. Leases

We have entered into one operating lease for real estate. This lease has a term of 78 months, and includes renewal terms which can extend the lease term by 60 months, which we include in the lease term when it is reasonably certain that we will exercise the option. As of June 30, 2023, our operating lease had a remaining lease term of 27 months. The right-of-use (ROU) asset is included in “Other assets” on our interim consolidated balance sheets as of June 30, 2023 and December 31, 2022, and represents our right to use the underlying asset for the lease term. Our obligations to make lease payments are included in both “Accrued expenses” and “Other long-term liabilities” on our interim consolidated balance sheets as of June 30, 2023 and December 31, 2022. The ROU asset was initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred, less any lease incentives received. The ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received.  

As of June 30, 2023 and December 31, 2022, ROU assets were $1.1 million and $1.3 million, respectively, and operating lease liabilities were $1.7 million and $2.0 million, respectively. We have entered into various short-term operating leases, primarily for clinical trial equipment, with an initial term of twelve months or less. These leases are not recorded on our balance sheets. All operating lease expense is recognized on a straight-line basis over the lease term. During each of the three months ended June 30, 2023 and 2022, we recognized $0.1 million in total lease costs. During each of the six months ended June 30, 2023 and 2022, we recognized $0.3 million in total least costs. In all periods, we recognized less than $0.1 million in short-term lease costs related to short-term operating leases.

Because the rate implicit in each lease is not readily determinable, we use our incremental borrowing rate to determine the present value of the lease payments. The weighted average incremental borrowing rate used to determine the initial value of ROU assets and lease liabilities was 11.0%, derived from a corporate yield curve based on a synthetic credit rating model using a market signal analysis. We have certain contracts for real estate which may contain lease and non-lease components which we have elected to treat as a single lease component.

ROU assets for operating leases are periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant, and Equipment – Overall, to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to recognize.  As of June 30, 2023 and December 31, 2022, we have not recognized any impairment losses for our ROU assets.

Maturities of operating lease liabilities as of June 30, 2023 were as follows (in thousands):

On May 11, 2021 (Closing Date) and as amended on May 17, 2021, May 23, 2022 and October 28, 2022 (Credit Agreement) we entered into the Credit Agreement with Oaktree Fund Administration, LLC as administrative agent (Oaktree) and the lenders party thereto (collectively, the Lenders) that provides for a five-year senior secured term loan facility in an aggregate original principal amount of up to $100.0 million, available to us in four tranches (collectively, the Term Loans).

Upon entering into the Credit Agreement in May 2021, we borrowed $15.0 million in term loans from the Lenders (Tranche A-1 Term Loans); upon receipt of written acceptance by the FDA of our NDA filing relating to the use of ganaxolone in CDD in September 2021 we borrowed $30.0 million of tranche A-2 term loans from the Lenders (Tranche A-2 Term Loans); and in March 2022, we borrowed $30.0 million in term loans from the Lenders that became available as a result of the approval by the FDA of ZTALMY oral suspension for the treatment of seizures associated with CDD in patients two years of age and older (Tranche B Term Loans). In May 2022, we entered into an amendment to extend the commitment date for the tranche C term loans (Tranche C Term Loans) commitment from June 30, 2023 to December 31, 2023, and to eliminate the commitment fees associated with the Tranche C Term Loans. Also in May 2022, we delivered to Oaktree a separate notice of commitment termination with respect to the tranche D term loans (Tranche D Term Loans) commitment. In October 2022, we entered into an amendment to, among other things, allow for the consummation of a revenue interest financing agreement (Revenue Interest Financing Agreement) with Sagard Health Royalty Partners (Sagard) and the transactions thereunder. In addition, the October 2022 amendment increased the exit fee due by us upon any repayment, whether as a prepayment or a scheduled repayment, of the principal of the loans under the Credit Agreement from 2.00% to 2.67%. Under the terms of the Credit Agreement, we may, at our sole discretion, borrow from the Lenders up to an additional $25.0 million in term loans subject to the following milestone event:

● Through December 31, 2023, $25.0 million of Tranche C Term Loans will be available for draw if we complete one or more financings (including through the issuance of common stock, convertible debt, subordinated debt, a synthetic royalty, or a sublicense) resulting in gross proceeds to us of at least $40.0 million and net proceeds to us of at least $36.0 million (Qualified Financing Condition). However, the availability of this tranche is also subject to either our current Phase 3 trial in RSE or a Phase 3 trial in TSC achieving statistical significance (p value < 0.05) across all primary endpoints and ganaxolone must be generally well tolerated, with a safety profile generally consistent with previous clinical trials. We do not currently anticipate data from either Phase 3 trial prior to December 31, 2023.

We satisfied the Qualified Financing Condition in connection with our November 2022 underwritten public offering; however, if we are unable to satisfy the remaining condition, we will not be able to draw down the remaining tranche of loans and may not be able to obtain alternative financing on commercially reasonable terms or at all. In addition, the Credit Agreement contains a minimum liquidity covenant that requires us to maintain cash and cash equivalents of at least $15.0 million from the funding date of the Tranche B Term Loans until the maturity of the Term Loans.

The Term Loans will be guaranteed by certain of our future subsidiaries (Guarantors). Our obligations under the Credit Agreement are secured by a pledge of substantially all of our assets and will be secured by a pledge of substantially all of the assets of the Guarantors.

The Term Loans mature on May 11, 2026 (Maturity Date). The Term Loans bear interest at a fixed per annum rate (subject to increase during an event of default) of 11.50%, and we are required to make quarterly interest payments until the Maturity Date. We are also required to make quarterly principal payments beginning on June 30, 2024 in an amount equal to 5.0% of the aggregate amount of the Term Loans outstanding on June 30, 2024, and continuing until the Maturity Date. On the Maturity Date, we are required to pay in full all outstanding Term Loans and other amounts owed under the Credit Agreement.

At the time of borrowing any tranche of the Term Loans, we are required to pay an upfront fee of 2.0% of the aggregate principal amount borrowed at that time. In addition, a commitment fee of 75 basis points per annum began to accrue on each of the tranche B, C, and D commitments for the period beginning 120 days after the funding date of the Tranche A-2 Term Loans, and continued until the applicable tranche was either funded or terminated, at which time the related commitment fees were due. The Tranche A-2 Term Loans were funded on September 27, 2021, and as such, we began accruing the commitment fees for tranche B, C, and D Term Loans 120 days later, on January 25, 2022. We drew down the additional $30.0 million of Tranche B Term Loans in March 2022, and paid less than $0.1 million in commitment fees related to Tranche B Term Loans. The May 2022 amendment eliminated the commitment fees related to the Tranche C Term Loans, and separately, we terminated the Tranche D Term Loans in May 2022.

We may prepay all or any portion of the Term Loans, and are required to make mandatory prepayments of the Term Loans from the proceeds of asset sales, casualty and condemnation events, and prohibited debt issuances, subject to certain exceptions. All mandatory and voluntary prepayments of the Term Loans are subject to prepayment premiums equal to (i) 4% of the principal prepaid plus a “make-whole” amount equal to the interest that would have accrued through May 11, 2023 if prepayment occurred on or before May 11, 2023, (ii) 4% of the principal prepaid if prepayment occurs after May 11, 2023 but on or before May 11, 2024, or (iii) 2% of the principal prepaid if prepayment occurs after May 11, 2024 but on or before May 11, 2025. If prepayment occurs after May 11, 2025, no prepayment premium is due.

We are also required to make mandatory prepayments of the Term Loans upon an event of default under the Credit Agreement resulting from the occurrence of a change of control.

In addition, we are required to pay an exit fee in an amount equal to 2.67% of all principal repaid, whether as a mandatory prepayment, voluntary prepayment, or a scheduled repayment. Prior to the October 2022 amendment to the Credit Agreement, the exit fee was 2.0%. The increase in the exit fee resulted in an additional $0.5 million of debt issuance costs that are classified as a contra-liability on the consolidated balance sheets and is being recognized as interest expense over the term of the loan using the effective interest method.

In addition to the minimum liquidity covenant, we are subject to a number of affirmative and restrictive covenants under the Credit Agreement, including limitations on our ability and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions, and enter into affiliate transactions, subject to certain exceptions. As of June 30, 2023, we were in compliance with all covenants.

Upon the occurrence of certain events, including but not limited to our failure to satisfy our payment obligations under the Credit Agreement, the breach of certain of our other covenants under the Credit Agreement, the occurrence of cross defaults to other indebtedness, or defaults related to enforcement action by the FDA or other

Regulatory Authority or recall of ganaxolone, Oaktree and the Lenders will have the right, among other remedies, to accelerate all amounts outstanding under the Term Loans and declare all principal, interest, and outstanding fees immediately due and payable.

In March 2022, we borrowed $30.0 million upon the approval by the FDA of ZTALMY for CDD and incurred debt issuance costs of $1.8 million, including the exit fee of $0.6 million, that are classified as contra-liabilities on our consolidated balance sheets and are being recognized as interest expenses over the term of the loan using the effective interest method.

In September 2021, we borrowed $30.0 million upon receipt of written acceptance by the FDA of our NDA filing relating to the use of ganaxolone in the treatment of CDD and incurred debt issuance costs of $1.2 million, including the exit fee of $0.6 million, that are classified as contra-liabilities on our consolidated balance sheets and are being recognized as interest expenses over the term of the loan using the effective-interest method.

In May 2021, we borrowed $15.0 million upon entering into the Credit Agreement and incurred debt issuance costs of $4.4 million, including the exit fee of $0.3 million, that are classified as a contra-liabilities on the consolidated balance sheet and are being recognized as interest expenses over the term of the loan using the effective-interest method.

For the six months ended June 30, 2023, we recognized interest expense of $5.3 million, of which $4.3 million was interest on the Term Loans and $1.0 million was non-cash interest expense related to the amortization of debt issuance costs.

Revenue Interest Financing Agreement

11. Revenue Interest Financing Agreement

On October 28, 2022 (Closing Date), we entered into the Revenue Interest Financing Agreement with Sagard pursuant to which we received $32.5 million (Investment Amount) to provide funding for our development and commercialization of ganaxolone and related pharmaceutical products, including the commercial launch of ZTALMY, and for working capital and general administrative purposes.

In  exchange for the Investment Amount, we have agreed to make quarterly payments to Sagard (Payments) as follows: (i) for each calendar quarter from and after the Closing Date through and including the quarter ended June 30, 2026, an amount equal to 7.5% of (a) our U.S. net sales of ZTALMY and all other pharmaceutical products that contain ganaxolone (Net Sales), in each case with any dosage form, dosing regimen, or strength, or any improvements related

thereto (collectively, Included Products) and (b) certain other payments received by us in connection with the manufacture, development and sale of the Included Products in the U.S. (Other Included Payments, and, together with Net Sales, Product Revenue); and (ii) for each calendar quarter following the calendar quarter ended June 30, 2026, an amount equal to (x) 15.0% of the first $100 million in annual Product Revenue of the Included Products and (y) 7.5% of annual Product Revenue of the Included Products in excess of $100 million.

The Payments are subject to a hard cap equal to 190% of the Investment Amount (Hard Cap) or $61.8 million. Sagard’s right to receive payments will terminate when Sagard has received payments in respect of the Included Products, including any additional payments described below, equal to the Hard Cap. Further, we have the right to make voluntary prepayments to Sagard, and such payments will be credited against the Hard Cap.

If Sagard has not received aggregate payments equaling at least 100% of the Investment Amount by December 31, 2027 or at least 190% of the Investment Amount by December 31, 2032 (each, a Minimum Amount), then we will be obligated to make a cash payment to Sagard in an amount sufficient to gross up Sagard up to the applicable Minimum Amount within a specified period of time after each reference date.

The obligations under the Revenue Interest Financing Agreement, including the Payments, will be guaranteed by certain of our future subsidiaries that are required to become a party thereto as guarantors (Guarantors).  Our obligations under the Revenue Interest Financing Agreement and the guarantee of such obligations are secured, subject to customary permitted liens and other agreed upon exceptions and subject to an intercreditor agreement with Oaktree as administrative agent for the lenders under our credit agreement (as described below, the Credit Agreement), by a pledge of substantially all of our and the Guarantors’ assets that relate to, or are used or held for use for, the development, manufacture, use and/or commercialization of ZTALMY and all other pharmaceutical products that contain ganaxolone in the U.S., including the Product Revenue, pursuant to the terms of the Security Agreement dated as of the Closing Date by and among us, the Guarantors from time to time party thereto, and Sagard (Security Agreement).

At any time, we have the right, but not the obligation (Call Option), to repurchase all, but not less than all, of Sagard’s interest in the Payments at a repurchase price (Put/Call Price) equal to: (a) on or before the third anniversary of the Closing Date, 160% of the Investment Amount; (b) after the third anniversary but on or prior to the fourth anniversary of the Closing Date, 180% of the Investment Amount; and (c) after the fourth anniversary of the Closing Date, 190% of the Investment Amount, in each case, less the aggregate of all of our payments in respect of the Payments made to Sagard prior to such date.

The Revenue Interest Financing Agreement contains certain restrictions on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions.  In addition, the Revenue Interest Financing Agreement contains a financial covenant that requires us to maintain at all times cash and cash equivalents in certain deposit accounts in an amount at least equal to (i) from the Closing Date until the repayment of the loans under the Credit Agreement, $15.0 million and (ii) thereafter, $10.0 million.

In connection with the Revenue Interest Financing Agreement, on the Closing Date, we entered into an amendment to the Credit Agreement with Oaktree, which is fully described in Note 10.

Issuance costs pursuant to the Revenue Interest Financing Agreement consisted primarily of advisory and legal fees and totaled $2.6 million. These issuance costs were recorded as a direct deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period the liability will be repaid. For the six months ended June 30, 2023, we estimated an effective annual interest rate of approximately 19%. Over the course of the Revenue Interest Financing Agreement, the actual interest rate will be affected by the amount and timing of net ZTALMY revenue recognized and changes in the timing of forecasted net ZTALMY revenue. On a quarterly basis, we will reassess the expected timing of the net ZTALMY revenue, recalculate the amortization and effective interest rate and adjust the accounting prospectively as needed.

Orion Collaboration Agreement

In July 2021, we entered into a collaboration agreement (Orion Collaboration Agreement) with Orion. The Orion Collaboration Agreement falls under the scope of ASC Topic 808, Collaborative Arrangements (ASC 808) as both parties are active participants in the arrangement that are exposed to significant risks and rewards. While this arrangement is in the scope of ASC 808, we analogize to ASC 606 for some aspects of this arrangement, including for the delivery of a good or service (i.e., a unit of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue on the consolidated statements of operations.

Under the terms of the Orion Collaboration Agreement, we granted Orion an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights with respect to commercializing biopharmaceutical products incorporating our product candidate ganaxolone (Licensed Products) in the European Economic Area, the United Kingdom and Switzerland (collectively, the Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially in the indications of CDD, TSC and RSE. We will be responsible for the continued development of Licensed Products and regulatory interactions related thereto, including conducting and sponsoring all clinical trials, provided that Orion may conduct certain post-approval studies in the Territory. Orion will be responsible, at Orion’s sole cost and expense, for the commercialization of any Licensed Product in the Field in the Territory.

Under the terms of the Orion Collaboration Agreement, we received a €25.0 million ($29.6 million) upfront payment from Orion in July 2021. In connection with the upfront fee, we agreed to provide Orion with the results of a planned genotoxicity study on the M2 metabolite of ganaxolone, a “Combined Micronucleus & Comet study in vivo.” In May 2022, the final study report was received, which confirmed that no genotoxicity was found, as measured by formation of micronuclei in the bone marrow or comet morphology in the liver. In the event that the results of the study were positive, based on the criteria set forth in the study’s protocol, Orion would have had the right to terminate the Orion Collaboration Agreement within ninety (90) days after its receipt of the final study report, and we would have been required to refund Orion seventy-five percent (75%) of the upfront fee. We are eligible to receive up to an additional €97 million in research and development reimbursement and cash milestone payments based on specific clinical and commercial achievements, as well as tiered royalty payments based on net sales ranging from the low double-digits to high teens for the oral programs and the low double-digits to low 20s for the IV program. Also, as part of the overall arrangement, we have agreed to supply the Licensed Products to Orion at an agreed upon price.

The Orion Collaboration Agreement shall remain effective until the date of expiration of the last to expire Royalty Term, which is defined as the period beginning on the date of the first commercial sale Licensed Product in such country and ending on the latest to occur of (a) the tenth (10th) anniversary of the first commercial sale of Licensed Product in such country, (b) the expiration of the last-to-expire licensed patent covering the manufacture, use or sale of such Licensed Product in such country, and (c) the expiration of regulatory exclusivity period, if any, for such Licensed

Product in such country. The Orion Collaboration Agreement has a term of at least ten (10) years since a commercial sale has yet to occur. The Orion Collaboration Agreement allows for termination in certain specific events, such as material breach, in the event Orion challenges the validity, enforceability or scope of the licensed patent rights, termination for forecast failure, insolvency and force majeure, none of which are probable at contract inception.

In accordance with the guidance, we identified the following commitments under the arrangement: (i) exclusive rights to develop, use, sell, have sold, offer for sale and import any product comprised of Licensed Product (License), (ii) development and regulatory activities (Development and Regulatory Activities), and (iii) requirement to supply Orion with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these three commitments represent distinct performance obligations for purposes of recognizing revenue or reducing expense, which we will recognize such revenue or expense, as applicable, as we fulfill these performance obligations.

At contract inception, we determined that the non-refundable portion of the upfront payment plus the research and development reimbursement constitutes the transaction price as of the outset of the Orion Collaboration Agreement. The refundable portion of the upfront payment and the future potential regulatory and development milestone payments were fully constrained at contract inception as the risk of significant revenue reversal related to these amounts had not yet been resolved. During 2022, the refundable portion of the upfront payment was determined to be included in the transaction price as the final genotoxicity study on the M2 metabolite of ganaxolone was received as described above, and the remaining $12.7 million of the upfront payment was recorded as collaboration revenue in the year ended December 31, 2022. The achievement of the future potential milestones is not within our control and is subject to certain research and development success and therefore carries significant uncertainty. As a result of the July 2023 EC approval of ZTALMY oral suspension for the adjunctive treatment of epileptic seizures associated with CDD in patients two to 17 years of age, we are now eligible under the Orion Collaboration Agreement to receive a commercial milestone payment of 10 million Euro, if commercial sales of ZTALMY commence in the Territory, due upon the earlier of (1) the first commercial sale of ZTALMY within two of a select set of countries consisting of Germany, France, Italy, Spain, and the United Kingdom or (2) the 18-month anniversary of the first commercial sale of ZTALMY in the Territory. We will reevaluate the likelihood of achieving these milestones at the end of each reporting period and adjust the transaction price in the period the risk is resolved. In addition, we will recognize any consideration related to sales-based milestones and royalties when the subsequent sales occur since those payments relate primarily to the License, which was delivered by us to Orion upon entering into the Orion Collaboration Agreement.

The transaction price was allocated to the three performance obligations based on the estimated stand-alone selling prices at contract inception. The stand-alone selling price of the License was based on a discounted cash flow approach and considered several factors including, but not limited to, discount rate, development timeline, regulatory risks, estimated market demand and future revenue potential using an adjusted market approach. The stand-alone selling price of the Development and Regulatory Activities and the Supply of Licensed Product was estimated using the expected cost-plus margin approach.

As of December 31, 2022, we allocated the transaction price to the performance obligations as described below and recorded the remaining $12.7 million of the upfront payment as collaboration revenue during the year ended December 31, 2022. During 2022, we amortized $1.1 million of the transaction price associated with the Development and Regulatory Services as a reduction of research and development costs. These reductions to transaction price resulted in a total contract liability of $15.1 million as of December 31, 2022. In accordance with ASC 210-20, the contract liability of $15.1 million was offset by a contract asset of $5.1 million related to the reimbursement of research and development costs, resulting in a net contract liability of $10.0 million as of December 31, 2022.

Transaction Price and Net Contract Liability as of December 31, 2022:

			Cumulative Collaboration
	Transaction		Revenue Recognized		Contract
	Price		as of December 31, 2022		Liability
License	$	21,660	$	21,660	$	-
Development and Regulatory Services		6,717		1,158		5,559
Supply of Licensed Product		9,503		-		9,503
	$	37,880	$	22,818		15,062
Less Total Contract Asset						5,079
Net Contract Liability					$	9,983

During the six months ended June 30, 2023, we amortized $0.8 million of the transaction price associated with the Development and Regulatory Services as a reduction of research and development costs. These reductions to the transaction price resulted in a total contract liability of $14.2 million as of June 30, 2023. In accordance with ASC 210-20, the contract liability of $14.2 million is offset by a contract asset of $4.0 million related to the reimbursement of research and development costs, resulting in a net contract liability of $10.2 million as of June 30, 2023.

Transaction Price and Net Contract Liability as of June 30, 2023:

	$	37,880	$	23,655		14,225
Less Total Contract Asset						3,992
Net Contract Liability					$	10,233

We incurred $2.0 million of incremental costs in connection with obtaining the Orion Collaboration Agreement. These contract acquisition costs were allocated consistent with the transaction price, resulting in $1.1 million of expense recorded to selling, general and administrative expense commensurate with the recognition of the License performance obligation and $0.9 million recorded as capitalized contract costs, included in other current assets and other assets, which are being amortized as Development and Regulatory Services and Supply of Licensed Product obligations are met.

We reevaluate the transaction price and the total estimated costs expected to be incurred to satisfy the performance obligations and adjust the deferred revenue at the end of each reporting period. Such changes will result in a change to the amount of collaboration revenue recognized and deferred revenue.

Tenacia Collaboration Agreement

On November 16, 2022 (Effective Date), we entered into a Collaboration and Supply Agreement (Tenacia Collaboration Agreement) with Tenacia Biotechnology (Shanghai) Co., Ltd. (Tenacia). The Tenacia Collaboration Agreement falls under the scope of ASC Topic 808, Collaborative Arrangements (ASC 808) as both parties are active participants in the arrangement that are exposed to significant risks and rewards. While this arrangement is in the scope of ASC 808, we analogize to ASC 606 for some aspects of this arrangement, including for the delivery of a good or service (i.e., a unit of account). Revenue recognized by analogizing to ASC 606 is recorded as collaboration revenue on the consolidated statements of operations.

Under the terms of the Tenacia Collaboration Agreement, we granted Tenacia an exclusive, royalty-bearing, sublicensable license to certain of our intellectual property rights to develop, commercialize and otherwise exploit certain products incorporating certain oral and intravenous formulations of our product candidate ganaxolone (Licensed Products) in Mainland China, Hong Kong, Macau and Taiwan (collectively, Territory) for the diagnosis, prevention and treatment of certain human diseases, disorders or conditions (Field), initially for the treatment of cyclin-dependent kinase-like 5 deficiency disorder, tuberous sclerosis complex and SE (including refractory and established SE) (collectively, the Initial Indications). The collaboration can be expanded to include additional indications and formulations of ganaxolone pursuant to a right of first negotiation.

Under the terms of the Tenacia Collaboration Agreement, Tenacia agreed to pay us an upfront cash payment of $10 million (the Upfront Fee) within forty-five (45) days after the Effective Date, which was paid in December 2022. In addition to the Upfront Fee, Tenacia has agreed to make cash payments to us upon the achievement of certain development, regulatory and sales-based milestones related to (i) the Initial Indications and (ii) the first new formulation or pro-drug of ganaxolone or any back-up compound of ganaxolone in a new indication (Selected Product) for which the parties amend the Tenacia Collaboration Agreement in connection with Tenacia’s exercise of its right of first negotiation and for which there is no other Licensed Product approved in China (for clarity, the milestone payments under this clause (ii) will only apply to one Selected Product), up to an aggregate amount of $256 million. Of the milestones, $15 million relates to regulatory approvals with separate milestones related to each of oral and intravenous formulations and the Selected Product, and an aggregate of $241 million of sales-based milestones are connected to annual revenue thresholds specific to each of the oral, intravenous and Selected Product formulations of ganaxolone. Tenacia has further agreed to pay us tiered royalty payments based on annual net sales of Licensed Products ranging from the low double digits to the mid-teens for each of the oral formulation, intravenous formulation and Selected Product formulation of Licensed Products. Tenacia’s obligations to pay royalties to us with respect to sales of a Licensed Product in each particular jurisdiction of the Territory will commence on the date of first commercial sale in such jurisdiction and expire upon the latest of (i) ten years following the first commercial sale of such Licensed Product in such jurisdiction, (ii) the expiration of the last-to-expire valid claim of any licensed patent rights that covers such Licensed Product in such jurisdiction and (iii) the expiration of all regulatory exclusivities for such Licensed Product in such jurisdiction. Royalty payments are subject to reduction in specified circumstances as set forth in the Tenacia Collaboration Agreement, including if net sales decrease by a certain percentage after the introduction of a generic product.

Tenacia will be primarily responsible for the development of Licensed Products in the Territory and regulatory interactions related thereto, including conducting and sponsoring clinical studies in the Field in the Territory to support regulatory filings in the Territory. All regulatory approvals filed by Tenacia in the Territory will be in the name of and owned by us unless otherwise required by applicable law, in which case such regulatory approvals would be in the name of and owned by Tenacia for the benefit of us. We and Tenacia agreed to enter into clinical and commercial supply agreements pursuant to which we will supply Tenacia with its requirements of Licensed Products necessary for Tenacia to develop and commercialize Licensed Products in the Field in the Territory. The parties entered into the clinical and commercial supply agreement in May 2023. The agreement contains pricing, delivery, acceptance, payment, termination, forecasting, and other terms consistent with the Tenacia Collaboration Agreement, as well as certain quality assurance, indemnification, liability and other standard industry terms. Tenacia will be responsible for, at Tenacia’s sole cost and expense, obtaining regulatory approval and commercializing the Licensed Product in the Field in Mainland China.

The term of the Tenacia Collaboration Agreement extends for so long as royalties are payable anywhere in the Territory. Subject to the terms of the Tenacia Collaboration Agreement, (i) for a specified period of time after the Effective Date, Tenacia may terminate the Tenacia Collaboration Agreement in its entirety for any or no reason upon written notice to us, and (ii) either party may terminate the Tenacia Collaboration Agreement for the other party’s material breach following a cure period or insolvency.

In accordance with the guidance, we identified the following commitments under the arrangement: (i) grant to Tenacia the exclusive rights to develop, commercialize and otherwise exploit Licensed Product in the Field in the Territory (License) and (ii) requirement to supply Tenacia with the Licensed Product at an agreed upon price (Supply of Licensed Product). We determined that these two commitments represent distinct performance obligations for purposes of recognizing revenue or reducing expense, which it will recognize such revenue or expense, as applicable, as it fulfills these performance obligations.

The transaction price was allocated to the two performance obligations based on the estimated stand-alone selling prices at contract inception. The stand-alone selling price of the License was based on a discounted cash flow approach and considered several factors including, but not limited to, discount rate, development timeline, regulatory risks, estimated market demand and future revenue potential using an adjusted market approach. The stand-alone selling price of the Supply of Licensed Product was estimated using the expected cost-plus margin approach.

As of December 31, 2022, we allocated the transaction price to the performance obligations as described below. There was no activity in the three and six months ended June 30, 2023. The cumulative collaboration revenue recognized as of June 30, 2023 is $3.0 million, which was the $3.0 million transaction price associated with the License as revenue for the year ended December 31, 2022. No license revenue was recorded in the three and six months ended June 30, 2023. There was a total contract liability of $7.0 million as of both June 30, 2023 and December 31, 2022. In accordance with ASC 210-20, the contract liability of $7.0 million is offset by a contract asset of $0.7 million, resulting in a net contract liability of $6.3 million as of both June 30, 2023 and December 31, 2022.

Transaction Price and Net Contract Liability as of June 30, 2023 and December 31, 2022:

			Cumulative Collaboration
	Transaction		Revenue Recognized		Contract
	Price		as of June 30, 2023 and December 31, 2022		Liability

	$	10,000	$	2,998		7,002
Less Total Contract Asset						700
Net Contract Liability					$	6,302

In December 2022, we incurred $1.0 million of incremental costs in obtaining the Tenacia Collaboration Agreement. These contract acquisition costs were allocated consistent with the transaction price, resulting in $0.1 million of expense recorded to General and administrative expense and $0.2 million recorded to cost of collaboration revenue in the period ended December 31, 2022, commensurate with the recognition of the License performance obligation, and $0.7 million recorded as capitalized contract costs, which will be amortized as Supply of License Product obligations are met.

We reevaluate the transaction price and the total estimated costs expected to be incurred to satisfy the performance obligations and adjust the deferred revenue at the end of each reporting period. Such changes will result in a change to the amount of collaboration revenue recognized and deferred revenue.

Biologix Distribution and Supply Agreement

In May 2023, we entered into an exclusive distribution and supply agreement (Biologix Agreement) with Biologix FZCo (Biologix), whereby Biologix has the right to distribute and sell ganaxolone in Algeria, Bahrain, Egypt, Iraq, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Tunisia and United Arab Emirates. In exchange for distribution rights, we will be the exclusive supplier of our products to Biologix on terms set forth in the respective agreements in exchange for a negotiated purchase price for the products. Upon execution of the Biologix Agreement, we received an upfront payment of $0.5 million which is to be amortized over the term of the agreement.

Summary of Significant Accounting Policies

Basis of Presentation

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of Marinus Pharmaceuticals, Inc. (a Delaware corporation) as well as the accounts of Marinus Pharmaceuticals Emerald Limited (an Ireland company incorporated in February 2021), a wholly owned subsidiary requiring consolidation. Marinus Pharmaceuticals Emerald Limited serves as a corporate presence in the European Union for regulatory purposes. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all information and disclosures necessary for a presentation of our financial position, results of operations and cash flows in conformity with generally accepted accounting principles in the U.S. (GAAP) for annual financial statements. In the opinion of management, these unaudited interim consolidated financial statements reflect all adjustments, consisting primarily of normal recurring accruals, necessary for a fair presentation of our financial position and results of operations and cash flows for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for the full year. These unaudited interim consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2022 and accompanying notes thereto included in our Annual Report on Form 10-K filed with the SEC on March 9, 2023.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from such estimates.

Product Revenue, net

Product Revenue, net

We recognize ZTALMY revenue in accordance with ASC 606 – Revenue from contracts with customers. Our revenue recognition analysis consists of the following steps: (i) identification of the promised goods in the contract; (ii) determination of whether the promised goods are performance obligations, including whether they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

Our first FDA approved product, ZTALMY, became available for commercial sale and shipment in the third quarter of 2022. We have three customers, one of which, Orsini Pharmaceutical Services, LLC (Orsini), a specialty pharmacy that dispenses ZTALMY directly to patients, represents over 99% of our ZTALMY revenue to date. Our contract with Orsini has a single performance obligation to deliver ZTALMY upon receipt of a purchase order, which is satisfied when Orsini receives ZTALMY. We recognize ZTALMY revenue at the point in time when control of ZTALMY is transferred to Orsini, which is upon delivery to Orsini. The transaction price that we recognize for

ZTALMY revenue includes an estimate of variable consideration. Shipping and handling costs to Orsini are recorded as selling, general and administrative expenses. The components of variable consideration include:

Trade Discounts and Allowances. We provide an incentive prompt payment discount to Orsini as explicitly stated in the contract with Orsini. This discount is recorded as a reduction of ZTALMY revenue and accounts receivable in the period in which the related ZTALMY revenue is recognized. We estimate the amount of variable consideration for all discounts and allowances using the expected value method.

Product Returns and Recall. We provide for ZTALMY returns in accordance with our Return Good Policy. We estimate the amount of ZTALMY that may be returned using the expected value method, and we present this amount as a reduction of ZTALMY revenue in the period the related ZTALMY revenue is recognized. In the event of a recall, we will promptly notify Orsini and will reimburse Orsini for direct administrative expenses incurred in connection with the recall as well as the cost of replacement product.

Government Rebates. We are subject to discount obligations under state Medicaid programs, Medicare, and the Tricare Retail Refund Program. We estimate reserves related to these discount programs and record these obligations in the same period the related revenue is recognized, resulting in a reduction of product revenue.

Patient Assistance. We offer a voluntary co-pay patient assistance program intended to provide financial assistance to eligible patients with a prescription drug co-payment required by payors and coupon programs for cash payors. The calculation of the current liability for this assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with ZTALMY that has been recognized as revenue but remains in the distribution channel inventories at the end of each reporting period.

Federal Contract Revenue

Federal Contract Revenue

We recognize federal contract revenue from the BARDA Contract in the period in which the allowable research and development expenses are incurred, and receivables associated with this revenue are included within accounts receivable on our interim consolidated balance sheets. This revenue is not within the scope of ASC 606 – Revenue from contracts with customers.

Short-term Investments

Short-term Investments

We classify our short-term investments as available-for-sale securities, which include U.S. government agency debt securities and U.S. treasury debt securities with original maturities of greater than three months. These securities are carried at fair market value, with unrealized gains and losses reported in comprehensive loss and accumulated other comprehensive income within stockholders’ equity. All of our investments were short-term in nature as of June 30, 2023.

Accounts Receivable, net

Accounts Receivable, net

Net trade receivables related to ZTALMY sales, which are recorded in net accounts receivable on the consolidated balance sheets, were approximately $1.8 million and $1.3 million as of June 30, 2023 and December 31, 2022, respectively. As of both June 30, 2023 and December 31, 2022, we had no allowance for doubtful accounts. An allowance for doubtful accounts is determined based on our assessment of the creditworthiness and financial condition of our customers, aging of receivables, as well as the general economic environment. Any allowance would reduce the net receivables to the amount that is expected to be collected. Payment terms for Orsini are approximately 30 days from the shipment date.

Excluding net trade receivables, accounts receivable represents amounts due to us under the BARDA contract for valid expenditures expected to be reimbursed to us under the terms of the BARDA contract and current amounts due to us from Orion Corporation (Orion) under the collaboration agreement (Note 12).

Inventory

Inventory

Inventories are recorded using actual costs and may consist of raw materials (ganaxolone API), work in process and finished goods. We began capitalizing inventory related to ZTALMY subsequent to the March 2022 FDA approval of ZTALMY, as the related costs were expected to be recoverable through the commercialization and subsequent sale of ZTALMY. Prior to FDA approval of ZTALMY, costs estimated at approximately $2 million for commercially saleable product and materials were incurred and included in research and development expenses. As a result, cost of product revenues related to ZTALMY will initially reflect a lower average per unit cost of materials into approximately the first half of 2024, as previously expensed inventory is utilized for commercial production and sold to customers.

Debt Issuance Costs

Debt Issuance Costs

Debt issuance costs incurred in connection with Note payable (Note 10) and revenue interest financing payable (Note 11) are amortized to interest expense over the term of the respective financing arrangement using the effective-interest method. Debt issuance costs, net of related amortization, are deducted from the carrying value of the related debt.

Contract Liabilities, net

Contract Liabilities, net

When consideration is received, or such consideration is unconditionally due, from a customer prior to completing our performance obligation to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities expected to be recognized as revenue or a reduction of expense within the 12 months following the balance sheet date are classified as current liabilities. Contract liabilities not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as long-term liabilities. In accordance with ASC 210-20, our contract liabilities are partially offset by our contract assets as further discussed in Note 12.

Liability Related to Revenue Interest Financing and Non-Cash Interest Expense

Liability Related to Revenue Interest Financing and Non-Cash Interest Expense

In October 2022, we recognized a liability related to the Revenue Interest Financing Agreement with Sagard Healthcare Royalty Partners, LP (Sagard) under ASC 470-10 Debt and ASC 835-30 Interest - Imputation of Interest. The initial funds we received from Sagard pursuant to the terms of the Revenue Interest Financing Agreement were recorded as a liability and will be accreted under the effective interest method upon the estimated amount of future royalty payments to be made pursuant to the Revenue Interest Financing Agreement. The issuance costs were recorded as a direct deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period the liability will be repaid as further discussed in Note 11. We estimated the total amount of future product revenue to be generated over the life of the Revenue Interest Financing Agreement, and a significant increase or decrease in these estimates could materially impact the liability balance and the related interest expense. If the timing or amounts of any estimated future revenue and related payments change, we will prospectively adjust the effective interest and the related amortization of the liability and related issuance costs.

Collaboration and Licensing Revenue

Collaboration and Licensing Revenue

We may enter into collaboration and licensing arrangements for research and development, manufacturing, and commercialization activities with counterparties for the development and commercialization of our product candidates. These arrangements may contain multiple components, such as (i) licenses, (ii) research and development activities, and (iii) the manufacturing of certain material. Payments pursuant to these arrangements may include non-refundable and refundable payments, payments upon the achievement of significant regulatory, development and commercial milestones, sales of product at certain agreed-upon amounts, and royalties on product sales. The amount of variable consideration is constrained until it is probable that the revenue is not at a significant risk of reversal in a future period.

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under a collaboration agreement, we perform the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether

they are capable of being distinct; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue as we satisfy each performance obligation.

We must develop estimates and assumptions that require judgment to determine the underlying stand-alone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the stand-alone selling price may include such estimates as forecasted revenues and costs, development timelines, discount rates and probabilities of regulatory and commercial success. We also apply significant judgment when evaluating whether contractual obligations represent distinct performance obligations, allocating transaction price to performance obligations within a contract, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time.
