Supernus Pharmaceuticals, Inc.

Notes to Consolidated Financial Statements

For the Three and Nine months ended September 30, 2016 and 2015

(unaudited)

1. Organization and Business

Supernus Pharmaceuticals, Inc. (the Company) was incorporated in Delaware on March 30, 2005, and commenced operations on December 22, 2005. The Company is a specialty pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, including neurological and psychiatric disorders. The Company markets two epilepsy products, Oxtellar XR and Trokendi XR, and has several proprietary product candidates in clinical development that address the psychiatry market.

The Company commenced the commercialization of Oxtellar XR and Trokendi XR in 2013.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc. and Supernus Europe Ltd., collectively referred to herein as “Supernus” or “the Company.” All significant intercompany transactions and balances have been eliminated in consolidation. The Company’s unaudited consolidated financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim financial information.

As permitted under Generally Accepted Accounting Principles in the United States (U.S. GAAP), certain notes and other information have been omitted from the interim unaudited consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the SEC.

In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the Company’s financial position, results of operations, and cash flows for the periods presented. These adjustments are of a normal recurring nature. The Company currently operates in one business segment.

The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the Company’s future financial results.

Marketable Securities

Marketable securities consist of investments in U.S. Treasuries, various U.S. governmental agency debt securities, corporate bonds and other fixed income securities. The Company’s investments are classified as available for sale. Such securities are carried at estimated fair value, with any unrealized holding gains or losses reported, net of any tax effects reported, as accumulated other comprehensive income, which is a separate component of stockholders’ equity. Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available for sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value, which is charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized when earned. The cost of securities sold is calculated using the specific identification method. The Company places all investments with government, industrial, or financial institutions whose debt is rated as investment grade. The Company classifies all available-for-sale marketable securities with maturities greater than one year from the balance sheet date as non-current assets.

The Company established the Supernus Supplemental Executive Retirement Plan (SERP) for the sole purpose of receiving funds for executives from a previous SERP and providing a continuing deferral program under the Supernus SERP. As of September 30, 2016 and December 31, 2015, the fair value of the SERP was $277,000, and $263,000, respectively. The SERP assets were held in mutual fund investments. The fair value of these assets is included within other non-current assets on the consolidated balance sheets. A corresponding noncurrent liability is also included in the consolidated balance sheets to reflect the Company’s obligation for the SERP. The Company has not made, and has no plans to make, contributions to the SERP. The securities are restricted in nature and can only be used for purposes of paying benefits under the SERP.

Table of Contents

Accounts Receivable, net

Accounts receivable are reported on the consolidated balance sheets at outstanding amounts, less an allowance for doubtful accounts and discounts. The Company extends credit without requiring collateral. The Company writes off uncollectible receivables when the likelihood of collection is remote. The Company evaluates the collectability of accounts receivable on a regular basis. An allowance, when needed, is based upon various factors including the financial condition and payment history of customers, an overall review of collections experience on other accounts, and economic factors or events expected to affect future collections experience. The Company recorded an allowance for bad debt of approximately $38,000 as of September 30, 2016. The Company recorded an allowance for expected sales deductions of approximately $5.2 million and $3.8 million as of September 30, 2016 and December 31, 2015, respectively.

Deferred Financing Costs

Deferred financing costs consist of financing costs incurred by the Company in connection with the closing of the Company’s 7.50% Convertible Senior Secured Notes due 2019 (the Notes) (see Note 8). The Company amortizes deferred financing costs over the term of the related debt using the effective interest method. When extinguishing debt, the related deferred financing costs are written off.

Revenue Recognition

Revenue from product sales is recognized when persuasive evidence of an arrangement exists; delivery has occurred and title to the product and associated risk of loss has passed to the customer; the price is fixed or determinable; collection from the customer has been reasonably assured; all performance obligations have been met; and returns and allowances can be reasonably estimated. Product sales are recorded net of estimated rebates, chargebacks, discounts, co-pay assistance and other deductions as well as estimated product returns (collectively, “sales deductions”).

Our products are distributed through wholesalers and pharmaceutical distributors. Each of these wholesalers and distributors will take title and ownership to the product upon physical receipt of the product and then distribute our products to pharmacies.

Sales Deductions

Allowances for estimated sales deductions are provided for the following:

· Rebates. Rebates include mandated discounts under the Medicaid Drug Rebate Program and the Medicare coverage gap program, as well as negotiated discounts with commercial healthcare providers. Rebates are amounts owed after the final dispensing of products to a benefit plan participant and are based upon contractual agreements or legal requirements with the public sector (e.g. Medicaid) and with private sector benefit providers. The allowance for rebates is based on statutory and contractual discount rates and expected claimed rebates paid based on a plan provider’s utilization. Rebates are generally invoiced and paid quarterly in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for known or estimated prior quarters’ unpaid rebates. If actual future rebates vary from estimates, we may need to adjust balances of such rebates to reflect the actual expenditures of the Company with respect to these programs, which would affect revenue in the period of adjustment.

· Chargebacks. Chargebacks are discounts that occur when contracted customers purchase directly from an intermediary distributor or wholesaler. Contracted customers, which currently consist primarily of Public Health Service institutions and federal government entities purchasing via the Federal Supply Schedule, generally purchase the product at a discounted price. The distributor or wholesaler, in turn, charges back the difference between the price initially paid by the distributor or wholesaler and the discounted price paid to the distributor or wholesaler by the customer. The allowance for distributor/wholesaler chargebacks is based on known sales to contracted customers.

· Distributor/Wholesaler deductions and discounts. U.S. specialty distributors and wholesalers are offered various forms of consideration including allowances, service fees and prompt payment discounts for distributing our products. Distributor allowances and service fees arise from contractual agreements with distributors and are generally a percentage of the purchase price paid by the distributors and wholesalers. Wholesale customers are offered a prompt pay discount for payment within a specified period.

· Co-pay assistance. Patients who pay in cash or have commercial insurance and meet certain eligibility requirements may receive co-pay assistance from the Company. The intent of this program is to reduce the patient’s out of pocket costs. Liabilities for co-pay assistance are based on actual program participation and estimates of program redemption using data provided by third-party administrators.

Table of Contents

· Returns. Sales of our products are not subject to a general right of return; however, the Company will accept product that is damaged or defective when shipped directly from our warehouse. The Company will accept expired product six months prior and up to 12 months subsequent to its expiry date. Product that has been used to fill patient prescriptions is no longer subject to any right of return.

Royalty Revenue

In the third quarter of 2014, the Company received a $30.0 million payment pursuant to a royalty agreement related to the purchase by HealthCare Royalty Partners III, L.P. (HC Royalty) of certain of the Company’s rights under the agreement with United Therapeutics Corporation related to the commercialization of Orenitram. We have recorded a non-recourse liability related to this transaction and have begun to amortize this amount to recognize royalty revenue as royalties are received by HC Royalty from United Therapeutics. We also recognize non-cash interest expense related to this liability that accrues at an effective interest rate determined based on projections of HC Royalty’s rate of return. We recognized royalty revenue of $3.5 million and royalty revenue of $2.0 million for the nine months ended September 30, 2016 and 2015, respectively. We recognized interest expense of $3.6 million and $2.5 million for the nine months ended September 30, 2016 and 2015, respectively.

Milestone Payments

Milestone payments on licensing agreements are recognized as revenue when the collaborative partner acknowledges completion of the milestone and substantive effort (i.e., effort consistent with amount of the milestone) was necessary to achieve the milestone. Management may recognize revenue contingent upon the achievement of a milestone in its entirety in the period in which the milestone is achieved only if the milestone meets all the criteria to be considered substantive. The Company recorded no milestone revenue during the three months and nine months ended September 30, 2016, and zero and $750,000 of milestone revenue during the three and nine months ended September 30, 2015, respectively.

Cost of Product Sales

The cost of product sales consists primarily of materials, third-party manufacturing costs, freight and distribution costs, allocation of labor, quality control and assurance, and other manufacturing overhead costs.

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities. These are measured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets to the amounts expected to be realized. (See Note 12)

The Company accounts for uncertain tax positions in its consolidated financial statements when it is more-likely-than-not that the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. The Company’s policy is to recognize any interest and penalties related to income taxes in income tax expense.

Recently Issued Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements.

In February 2016, FASB issued ASU No. 2016-02, “Leases (Topic 842).” The standard requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements.

In April 2015, FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU more closely aligns the treatment of debt issuance costs with debt discounts and premiums and requires debt issuance costs to be presented as a direct deduction from the carrying amount of the related debt. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. This guidance was applied on a retrospective basis. The adoption of ASU 2015-03 resulted in a reclassification of deferred financing costs of $104,000 from asset to liability classification on the Company’s consolidated December 31, 2015 financial statements.

In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”. ASU 2014-09 will eliminate transaction-and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principles-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016. The FASB has voted to approve a one-year deferral, changing the effective date to annual reporting periods beginning after December 15, 2017, with early adoption being permitted for periods beginning after December 15, 2016. Entities can transition to the standard either retrospectively or as a cumulative effect adjustment as of the date of adoption. Presently, the Company is assessing what effect the adoption of ASU 2014-09 will have on our consolidated financial statements and accompanying notes and has not yet selected a method of adoption.

3. Fair Value of Financial Instruments

The fair value of an asset or liability should represent the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Such transactions to sell an asset or transfer a liability are assumed to occur in the principal or most advantageous market for the asset or liability. Accordingly, fair value is determined based on a hypothetical transaction at the measurement date, considered from the perspective of a market participant rather than from a reporting entity’s perspective.

The Company reports assets and liabilities that are measured at fair value using a three tier or level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

· Level 1—Inputs are unadjusted quoted prices in active markets for identical assets that the Company has the ability to access at the measurement date.

· Level 2—Inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (interest rates, yield curves, etc.) and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

· Level 3—Unobservable inputs that reflect the Company’s own assumptions, based on the best information available, including the Company’s own data.

In accordance with the fair value hierarchy described above, the following tables show the fair value of the Company’s financial assets and liabilities that are required to be measured at fair value, in thousands:

The fair value of the restricted marketable securities is included within other non-current assets in the consolidated balance sheets.

The Company’s Level 1 assets include cash held with banks and money market funds.

Level 2 assets include the SERP assets, commercial paper and investment grade corporate bonds and other fixed income securities. Level 2 securities are valued using third-party pricing sources that apply applicable inputs and other relevant data into their models to estimate fair value.

Level 3 liabilities include the estimated fair value of the interest make-whole liability associated with the Company’s Notes, which are recorded as derivative liabilities.

The fair value of the interest make-whole liability of the Notes was calculated using a binomial-lattice model with the following key assumptions as of September 30, 2016, unaudited:

Volatility		45%
Stock Price as of September 30, 2016		$24.73 per share
Credit Spread		900 bps
Term		7 months
Dividend Yield		0.0%

Significant changes to these assumptions could result in increases/decreases to the fair value of the derivative liabilities.

Changes in the fair value of the interest make-whole liability are recognized as a component of other income (expense) in the Consolidated Statements of Operations. The following table presents information about the Company’s Level 3 liabilities as of December 31, 2015 and September 30, 2016 that are included in the non-current liabilities section of the consolidated balance sheets, in thousands:

Table of Contents

The carrying value, face value and estimated fair value of the Notes was approximately $5.8 million, $6.6 million and $31.2 million, respectively, as of September 30, 2016. The fair value was estimated based on actual trade information as well as quoted prices provided by bond traders, which would be characterized within Level 2 of the fair value hierarchy. This fair value amount gives recognition to the value of the interest make-whole liability and the value of the conversion option, which upon issuance were accounted for as derivative liabilities and additional paid-in-capital, respectively.

The carrying amounts of other financial instruments, including accounts receivable, accounts payable and accrued expenses, approximate fair value due to their short-term maturities. Unrestricted marketable securities held by the Company were as follows, in thousands:

The Company prevailed in a lawsuit related to Oxtellar XR in February 2016, at which time the Company reduced deferred legal fees and began amortizing the costs associated with that litigation.

Table of Contents

The net book value of intangible assets was $15.5 million as of September 30, 2016 and was $1.0 million as of December 31, 2015. The increase in intangible assets reflects the successful outcome of the lawsuit related to Oxtellar XR in February 2016. There is an offsetting reduction in the amount carried as deferred legal fees, as described above.

Amortization expense on intangible assets was approximately $0.3 million and $0.9 million for the three and nine months ended September 30, 2016 and was approximately $0.1 million and $0.2 million for the three and nine months ended September 30, 2015, respectively.

10. Share-Based Payments

The Company has adopted the Supernus Pharmaceuticals, Inc. 2012 Equity Incentive Plan (the 2012 Plan), which is stockholder approved, and provides for the grant of stock options and certain other awards, including stock appreciation rights (SAR), restricted and unrestricted stock, stock units, performance awards, cash awards and other awards that are convertible into or otherwise based on the Company’s common stock, to the Company’s key employees, directors, and consultants and advisors. The 2012 Plan is administered by the Company’s Board of Directors and provides for the issuance of up to 8,000,000 shares of the Company’s common stock upon the exercise of stock awards. Option awards are granted with an exercise price equal to the estimated fair value of the Company’s common stock at the grant date. Those option awards generally vest in four annual installments, starting on the first anniversary of the date of grant and have ten year contractual terms. Option awards granted to the directors generally vest over a one-year-term. Share-based compensation recognized related to the grant of employee and non-employee stock options, SAR, potential Employee Stock Purchase Plan (ESPP) awards and non-vested stock was as follows, in thousands:

11. Earnings per Share

Basic income per common share is determined by dividing income attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted income per share is computed by dividing the income attributable to common stockholders by the weighted-average number of common share equivalents outstanding for the period. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants, SARs, and potential ESPP awards, and the if-converted method is used to determine the dilutive effect of the Company’s Notes.

The following common stock equivalents were excluded in the calculation of diluted income per share because their effect would be anti-dilutive as applied to the income from continuing operations applicable to common stockholders for the three and nine months ended September 30, 2016 and 2015:

12. Income Taxes

During the three and nine months ended September 30, 2016, the Company had pre-tax income of $19.1 million and $34.8 million, respectively. The provision for federal and state income taxes related to the pre-tax income has been largely offset by the utilization of available net operating loss carryforwards (NOLs).

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. As of September 30, 2016, primarily because in the current year we achieved three years of cumulative pretax income in the U.S. federal tax jurisdiction, management determined that there is sufficient positive evidence to conclude that it is more likely than not that deferred taxes of $42.3 million are realizable. The Company therefore reduced the valuation allowance accordingly.

Our effective income tax rates were (120.9%) and 6.0% for the nine months ended September 30, 2016 and 2015, respectively. During the third quarter, we recorded an income tax benefit of approximately $42.7 million as a result of the company releasing the valuation allowance on the deferred taxes that are realizable. This valuation allowance release causes the effective tax rate to be significantly different from our historical annual effective tax rate.

13. Commitments and Contingencies

The Company has concurrent leases for office and lab space that extend through April 2020. The Company may elect to extend the term of the leases for an additional five-year term. The leases provide for a tenant improvement allowance of approximately $2.1 million in aggregate. During the three and nine months ended September 30, 2016, none of the allowance was utilized. During the three and nine months ended September 30, 2015, $107,000 and $215,000, respectively, of the allowance was utilized and is included in fixed assets and deferred rent. As of September 30, 2016, $0.5 million remains available for tenant improvements.

Rent expense for the leased facilities and leased vehicles for the Company’s sales representatives for the three and nine months ended September 30, 2016 were approximately $0.7 million and $2.0 million, respectively. Rent expense for the leased facilities and leased vehicles for the three and nine months ended September 30, 2015 were approximately $0.7 million and $2.0 million, respectively.

The Company has obtained exclusive licenses from third parties for proprietary rights to support the product candidates in the Company’s psychiatry portfolio. Under license agreements with Afecta Pharmaceuticals, Inc. (Afecta), the Company has obtained exclusive worldwide rights to selected product candidates, including an exclusive license to SPN-810 (molindone hydrochloride). The Company does not owe any future milestone payments for SPN-810. The Company is obligated to pay royalties in the low-single digits to Afecta based on worldwide net sales of SPN-810.

The Company has also entered into a purchase and sale agreement with Rune Healthcare Limited (Rune), where the Company obtained the exclusive worldwide rights to a product concept from Rune. There are no future milestone payments due to Rune under this agreement. If the Company receives approval to market and sell any products based on the Rune product concept for SPN-809 (viloxazine hydrochloride), the Company is obligated to pay royalties to Rune based on net sales worldwide in the low-single digits.

14. Subsequent Event

Subsequent to September 30, 2016, holders of the Notes converted approximately $3.0 million of the Notes. We issued a total of approximately 0.6 million shares of common stock in conversion of the principal amount of the Notes and accrued interest thereon resulting in a remaining Note balance of $3.6 million.

Overview

We are a specialty pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases.

Oxtellar XR and Trokendi XR are the first once-daily extended release oxcarbazepine and topiramate products indicated for patients with epilepsy in the U.S. market. These products differ from immediate release products by offering once-daily dosing and unique pharmacokinetic characteristics which we believe can result in very positive clinical outcomes for some patients. We believe a once-daily dosing regimen improves adherence, making it more probable that patients maintain sufficient levels of medication in their bloodstream to protect against seizures. In addition, the unique smooth and steady pharmacokinetic profiles of our once-daily formulations reduce the peak to trough fluctuation in blood level that are typically associated with immediate release products, which we believe may result in increased adverse events (AEs), more symptomatic side effects and decreased efficacy.

In addition, we are developing multiple product candidates in psychiatry to address large unmet medical needs and market opportunities. With SPN-810 (molindone hydrochloride), we are developing a product candidate to treat impulsive aggression (IA) in patients who have attention deficit hyperactivity disorder (ADHD). There are currently no approved products indicated for the treatment of IA. We subsequently plan to develop SPN-810 for treatment of IA in other CNS diseases, such as autism, bipolar disorder, schizophrenia, and some forms of dementia. With SPN-812 (viloxazine hydrochloride), we are developing this product candidate to treat patients who have ADHD.

The table below summarizes our current pipeline of novel products and product candidates.

Product	Indication	Status
Oxtellar XR	Epilepsy	Launched
Trokendi XR	Epilepsy	Launched
Trokendi XR	Migraine Prophylaxis	Tentative Approval
SPN-810	Impulsive Aggression*	Phase III
SPN-812	ADHD	Phase IIb completed
SPN-809	Depression	Phase II ready

* Initial program is in patients with ADHD, with a plan to follow on in other indications, such as IA in patients with autism, bipolar disorder, schizophrenia, and some forms of dementia.

Table of Contents

We are continuing to expand our intellectual property portfolio to provide additional protection for our technologies, products, and product candidates. We currently have seven U.S. patents issued covering Oxtellar XR and six U.S. patents issued covering Trokendi XR, providing patent protection expiring no earlier than 2027 for each product.

Commercial Products

Trokendi XR

Trokendi XR, the first once-daily extended release topiramate product indicated for patients with epilepsy in the U.S. market, is designed to improve patient adherence over immediate release products, as these must be taken multiple times per day.

In August 2016, we received tentative approval to expand the label for Trokendi XR to include the indication of prophylaxis of migraine headache in adults. We continue to prepare and will be ready to launch the migraine indication soon after receiving full FDA approval.

Oxtellar XR

Oxtellar XR is the only once-daily extended release oxcarbazepine product indicated for the treatment of patients with epilepsy in the U.S. as adjunctive therapy.

In a retrospective medical chart review of 200 patients treated with immediate release oxcarbazepine or Oxtellar XR, Oxtellar XR was associated with a significantly lower rate of inpatient hospitalization stays, lower rate of emergency department visits, and a higher rate of compliance. The patient charts were obtained from 17 geographically and clinically diverse sites across the U.S. and included non-academic and academic affiliated practices, general neurology, pediatric neurology, and epilepsy centers.

We expect the number of prescriptions filled for Oxtellar XR and Trokendi XR to continue to increase through the end of 2016 and in subsequent years. Data from Intercontinental Marketing Services (IMS) shows 370,397 prescriptions filled for both drugs during the nine months ended September 30, 2016, representing a growth of 39% as compared to the 266,546 prescriptions reported for the nine months ended September 30, 2015. For the three months ended September 30, 2016, data from IMS shows 131,308 prescriptions filled for both drugs, representing a growth of 30.3% as compared to the 100,770 prescriptions reported for the three months ended September 30, 2015.

We have received Paragraph IV Notice Letters concerning Oxtellar XR and Trokendi XR from various third-parties, asserting that our patents are invalid, or that our patents are not infringed by their formulations, or both. In response to these Paragraph IV notice letters, we have initiated litigation against these third parties alleging infringement of our intellectual property rights. We intend to vigorously defend our intellectual property rights in each of these cases. We anticipate continuing to incur substantial amounts of legal fees and related expenses for these cases as they progress. On February 8, 2016, the Company announced a court ruling that three patents covering Oxtellar XR were valid and that Actavis, plc infringed two of these three patents by submitting an abbreviated new drug application (ANDA) to the FDA. (See Part II, Item 1—Legal Proceedings in this Quarterly Report on Form 10-Q for additional information).

Product Candidates

SPN-810

We are developing SPN-810 as a novel treatment for IA in patients who have ADHD. Our Phase III clinical trial (P301) is being conducted under a Special Protocol Assessment (SPA). SPN-810 has been granted fast-track designation by the FDA. We initiated two Phase III clinical trials in 2015 (P301 and P302) and began dosing patients during the first quarter of 2016. In addition, we began enrolling patients in the open-label extension study during 2016. We expect patient enrollment to continue into 2017.

SPN-812

SPN-812 is being developed as a novel non-stimulant treatment for ADHD. We completed a Phase IIb dose ranging trial and recently announced topline results. The trial met the primary endpoint, demonstrating that SPN-812 at daily doses of 400 mg, 300 mg, and 200 mg achieved a statistically significant improvement in the symptoms of ADHD when compared to placebo. All SPN-812 doses tested in the trial were well tolerated. Of the patients treated with SPN-812, only 6.7% discontinued due to an AE. In addition, 87% of patients who completed the trial elected to enroll in the ongoing open-label extension.

At the end of the SPN-812 study, 400 mg, 300 mg and 200 mg doses were statistically significant compared to placebo in the primary endpoint. Patients receiving SPN-812 400 mg, 300 mg and 200 mg had a -19.0 point change (p=0.021), -18.6 point change (p=0.027) and a -18.4 point change (p=0.031) from baseline, respectively, in the primary endpoint vs. -10.5 for placebo.

Table of Contents

With respect to the effect size, patients receiving SPN-812 400 mg, 300 mg and 200 mg had a median effect size of 0.63, 0.60 and 0.55, respectively. Patients receiving SPN-812 100 mg had a -16.7 point change from baseline in the primary endpoint and a median effect size of 0.46, which did not quite reach statistical significance (p=0.089) in this relatively low number of patients.

In addition, SPN-812 400 mg, 300 mg and 200 mg met the Clinical Global Impression Severity (CGI-S) secondary endpoint with p- values of 0.014, 0.015 and 0.031, respectively, compared to placebo.

Based on these positive results in children with ADHD and the positive Phase IIa results in adults with ADHD, Supernus plans to have an end-of-Phase II meeting with the U.S. Food and Drug Administration (FDA) after which it will initiate Phase III clinical testing.

We expect to incur increasing amount of research and development expenses related to the continued development of each of our product candidates, with a total cost of approximately $100 million for each of the two programs, from 2016 through FDA approval.

Collaboration Update

Shire announced positive results of SHP465 Safety and Efficacy Study in Children and Adolescents with ADHD. The study addresses a key FDA requirement, keeping SHP465 on track for resubmission in the fourth quarter of 2016 and potential launch in second half of 2017, if it is approved by the FDA. SHP465 was originally developed by Shire Laboratories, the former division of Shire which subsequently became Supernus Pharmaceuticals. Based on the agreement between Supernus and Shire, Shire will pay to Supernus a single digit percentage royalty on net sales of the product.

Critical Accounting Policies and the Use of Estimates

The significant accounting policies and bases of presentation for our consolidated financial statements are described in Note 2 “Summary of Significant Accounting Policies.” The preparation of our consolidated financial statements in accordance with Generally Accepted Accounting Principles (GAAP), requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

We believe the following accounting policies and estimates to be critical:

Revenue Recognition

Revenue from product sales is recognized when: persuasive evidence of an arrangement exists; delivery has occurred and title to the product and associated risk of loss has passed to the customer; the price is fixed or determinable; collection from the customer has been reasonably assured; all performance obligations have been met; and returns and allowances can be reasonably estimated. Product sales are recorded net of estimated rebates, chargebacks, discounts, co-pay assistance and other deductions as well as estimated product returns (collectively, “sales deductions”).

We derive our estimated sales deductions from an analysis of historical levels of deductions specific to each product. In addition, we also consider the impact of anticipated changes in product price, sales trends and changes in managed care coverage and co-pay assistance.

Accounting for Non-Recourse Liability related to Sale of Future Royalties

In July 2014, we sold certain royalty rights for $30.0 million to HealthCare Royalty Partners (HC Royalty). These royalty rights related to the approved product Orenitram, marketed by United Therapeutics, Inc. Under the relevant accounting guidance, due to a limit on the rate of return that HC Royalty can earn under the arrangement, this transaction is accounted for as debt in accordance with ASC 470-10-25 and is amortized using the effective interest method over the expected life of the arrangement. We have no obligation to repay any amounts to HC Royalty. In order to record the amortization of the liability, we are required to estimate the total amount of future royalty payments to be received by HC Royalty under the License Agreement. The sum of these amounts less the net proceeds we received of $30.0 million will be recorded as non-cash interest expense over the life of the liability. Consequently, we impute interest on the unamortized portion of the liability and record non-cash interest expense using an imputed effective interest rate. We will periodically assess the expected royalty payments, and to the extent such payments are greater or less than our initial estimate, we will adjust the amortization of the liability and interest rate. As a result of this accounting, even though we do not retain HC Royalty’s share of the royalties, we will continue to record non-cash revenue related to those royalties until the amount of the associated liability and related interest is fully amortized.

Deferred Legal Fees

Deferred legal fees are comprised of costs incurred in connection with the defense of patents for Oxtellar XR and Trokendi XR. Amortization of the deferred legal fees will begin upon successful outcome of the on-going litigation. Deferred legal fees will be charged to expense in the event of an unsuccessful outcome of the on-going litigation.

Research and Development Expenses

Research and development (R&D) expenditures are expensed as incurred. Research and development costs consist primarily of employee-related expenses, including salaries and benefits; share-based compensation expense; expenses incurred under agreements with clinical research organizations (CROs), investigative sites, consultants and other vendors that conduct the Company’s clinical trials; the cost of acquiring and manufacturing clinical trial materials; the cost of manufacturing materials used in process validation, to the extent that those materials are manufactured prior to receiving regulatory approval for those products and are not expected to be sold commercially; facilities costs that do not have an alternative future use; related depreciation and other allocated expenses; license fees for and milestone payments related to in-licensed products and technologies; and costs associated with animal testing activities and regulatory approvals.

Table of Contents

Accrued Clinical Expenses

Clinical trials are inherently complex, often involve multiple service providers, and can include payments made to investigator physicians at study sites. Because billing for services often lags by a substantial amount of time, we often are required to estimate a significant portion of our accrued clinical expenses. This process involves reviewing open contracts and communicating with our subject matter expert personnel and the appropriate service provider personnel to identify services that have been performed on our behalf. We accrue for the estimated but unbilled services performed and the associated costs incurred.

Payments to service providers can either be based on hourly rates for services or based on performance driven milestones. When accruing clinical expenses, we estimate the time period over which services will be performed during the life of the entire clinical program, the total cost of the program, and the level of effort to be expended in each intervening period. To the maximum extent possible, we work with each service provider to provide an estimate for unbilled services as of the end of the calendar quarter. This includes estimates for payments to site investigators. We work diligently to minimize, if not eliminate, estimates based solely on company generated calculations. If the service provider underestimates or overestimates the cost associated with a trial or service at any given point in time, adjustments to research and development expenses may be necessary in future periods. Historically, our estimated accrued clinical expenses have closely approximated actual expenses incurred.

Net Product Sales. The increase in net product sales for the three months ended September 30, 2016 as compared to the three months ended September 30, 2015 was primarily driven by increased prescriptions. Price increases also contributed to the period over period increases in net product sales. Net product sales are based on gross revenue from shipments to distributors, less estimates for discounts, rebates, other sales deductions and returns. The table below lists our net product sales by product comparison, in thousands, unaudited:

Oxtellar XR	13,928		8,710		59.9	%
Total	$	55,618	$	38,551	44.3	%

Royalty Revenue. Revenue of $1.1 million and $0.8 million generated during the three months ended September 30, 2016 and September 30, 2015, respectively, was non-cash revenue generated pursuant to an agreement with Healthcare Royalty Partners III, L.P. (HC Royalty).

Cost of Product Sales. Cost of product sales during the three months ended September 30, 2016 was $3.4 million as compared to $2.2 million for the three months ended September 30, 2015, an increase of $1.2 million or 52.5%. This increase is primarily due to sales increases.

Research and Development Expenses. R&D expenses during the three months ended September 30, 2016 were $7.9 million as compared to $9.1 million for the three months ended September 30, 2015, a decrease of $1.2 million or 13.8%. This decrease was primarily due to the completion of the Phase IIb trial for SPN-812. We expect R&D costs to increase going forward into 2017, as we continue to advance these trials and the related development activities for both of these programs.

Selling, General and Administrative Expenses. Our selling, general and administrative (SG&A) expenses were $25.7 million during the three months ended September 30, 2016 as compared to $22.9 million for the three months ended September 30, 2015, an increase of $2.8 million or 12.1%. The increase in SG&A expenses is primarily due to support of our commercial products, and development of promotional material in preparation for the launch of the migraine indication for Trokendi XR soon after receiving FDA approval.

Interest Income. During the three months ended September 30, 2016 and 2015, we recognized $0.4 million and $0.2 million, respectively, of interest income earned on our cash and marketable securities.

Interest Expense. Interest expense was $0.2 million during the three months ended September 30, 2016 as compared to $0.3 million incurred for the three months ended September 30, 2015. The decrease was due to a decrease in the principal amount of our outstanding 7.5% Convertible Senior Secured Notes due in 2019 (the Notes) from $9.7 million at September 30, 2015 to $6.6 million at September 30, 2016.

Interest Expense-non-recourse royalty liability - Interest expense related to our non-recourse royalty liability was $1.0 million and $1.0 million for the three months ended September 30, 2016 and 2015, respectively. This non-cash expense item was primarily due to an increase in the expected royalties forecast related to Orenitram.

Changes in Fair Value of Derivative Liability. During the three months ended September 30, 2016, we recognized a non-cash gain of $0.1 million related to a change in estimated fair value of the interest make-whole derivative liability related to our Notes. This gain is primarily due to the passage of time.

Loss on Extinguishment of Debt. During the three months ended September 30, 2016, there was no loss on extinguishment of debt as no Notes were converted. During the three months ended September 30, 2015, we recognized a non-cash loss on extinguishment of debt of $25,000 related to the conversion of $1.0 million of our Notes.

Income Tax. During the three months ended September 30, 2016, we recorded $42.7 million of current tax benefit related to releasing all of our valuation allowance on deferred tax assets. During the three months ended September 30, 2015, we recorded $0.1 million of current tax expense related to an increase in our reserve for an uncertain tax position related to the Alternative Minimum Tax.

Net Income. We realized net income of $61.8 million during the three months ended September 30, 2016, compared to net income of $3.9 million during the three months ended September 30, 2015, an increase of $57.9 million. This change was primarily due to the revenue generated from our two commercial products, Oxtellar XR and Trokendi XR, and the release of valuation allowance on deferred tax assets of $42.3 million.

Royalty Revenue. Revenue of $3.5 million and $2.0 million generated during the nine months ended September 30, 2016 and 2015, respectively, was non-cash revenue generated pursuant to an agreement with HC Royalty.

Cost of Product Sales. Cost of product sales during the nine months ended September 30, 2016 was $8.2 million as compared to $5.6 million for the nine months ended September 30, 2015, an increase of $2.6 million or 45.9%. This increase was primarily due to sales increases.

Table of Contents

Research and Development Expenses. R&D expenses during the nine months ended September 30, 2016 were $29.5 million as compared to $19.7 million for the nine months ended September 30, 2015, an increase of $9.8 million or 50.0%. This increase was due to the continuation of two Phase III trials for SPN-810; a Phase IIb trial for SPN-812; manufacture of SPN-810 and SPN-812 clinical trial materials, and manufacturing scale-up activities. We expect R&D costs to continue to increase into 2017, as we continue to advance these trials and the related development activities for both of these programs.

Selling, General and Administrative Expenses. Our SG&A expenses were $77.0 million during the nine months ended September 30, 2016 as compared to $65.5 million for the nine months ended September 30, 2015, an increase of $11.5 million or 17.2%. The increase in SG&A expenses was primarily due to support of our commercial products, the development of promotional material in preparation for the launch of the migraine indication for Trokendi XR soon after receiving full FDA approval, as well as supply chain and medical affairs programs to support our commercial products.

Interest Income. During the nine months ended September 30, 2016 and September 30, 2015, we recognized $1.1 million and $0.4 million, respectively, of interest income earned on our cash and marketable securities.

Interest Expense. Interest expense was $0.6 million during the nine months ended September 30, 2016 as compared to $1.0 million incurred for the nine months ended September 30, 2015. The decrease of $0.4 million was primarily due to a decrease in the principal amount of our outstanding Notes from $9.7 million at September 30, 2015 to $6.6 million at September 30, 2016.

Interest Expense-non-recourse royalty liability - Interest expense related to our non-recourse royalty liability was $3.6 million and $2.5 million for the nine months ended September 30, 2016 and 2015, respectively. This non-cash expense item was primarily due to an increase in the expected royalties forecast related to Orenitram.

Changes in Fair Value of Derivative Liability. During the nine months ended September 30, 2016, we recognized a non-cash gain of $0.3 million related to a change in estimated fair value of the interest make-whole derivative liability related to our Notes. This gain was primarily due to the passage of time. During the nine months ended September 30, 2015, we recognized a non-cash credit of $0.1 million related to a change in estimated fair value of the warrant liability of $0.4 million, offset by $0.5 million of interest make-whole derivative liability related to our Notes. This loss was primarily due to the increase of our stock price.

Loss on Extinguishment of Debt. During the nine months ended September 30, 2016, we recognized a non-cash loss on extinguishment of debt of $0.4 million related to the conversion of $2.0 million of our Notes. During the nine months ended September 30, 2015, we recognized a non-cash loss on extinguishment of debt of $2.4 million related to the conversion of $26.3 million of our Notes.

Income Tax. During the nine months ended September 30, 2016, we recorded $42.1 million of current tax benefit related to releasing all of our valuation allowance on deferred tax assets. During the nine months ended September 30, 2015, we recorded $0.5 million of current tax expense related to an increase in our reserve for an uncertain tax position related to the Alternative Minimum Tax.

Net Income. We realized net income of $76.9 million during the nine months ended September 30, 2016, compared to net income of $7.1 million during the nine months ended September 30, 2015, an increase of $69.8 million. This change was primarily due to the revenue generated from our two commercial products, Oxtellar XR and Trokendi XR, and the release of the valuation allowance on deferred tax assets.

Liquidity and Capital Resources

We believe with continued increased levels of net product sales, we will have sufficient resources to finance our operations, including the increased R&D expenses for our clinical programs. We expect to incur significantly higher R&D expenses to support the development of SPN-810 and SPN-812 including the late stage trials for each.

Our working capital at September 30, 2016 was $66.6 million, an increase of $17.6 million compared to our working capital of $49.0 million at December 31, 2015. Our long term marketable securities at September 30, 2016 were $67.0 million, an increase of $12.0 million compared to our long term marketable securities of $55.0 million at December 31, 2015.

Our stockholders’ equity increased by $85.4 million during the nine months ended September 30, 2016 primarily as a result of the issuance of shares related to the conversion of our Notes, coupled with net income of $76.9 million.

We expect to continue to incur significant sales and marketing expenses related to the commercial support of Oxtellar XR and Trokendi XR. In addition, we expect to incur substantial expenses related to our R&D efforts, primarily related to the development of SPN-810 and SPN-812 as we continue to advance these clinical programs.

In addition to income from operations, we have historically financed our business through the sale of our debt and equity securities. Our most recent financing occurred on May 3, 2013, when we issued $90.0 million aggregate principal amount of Notes to qualified institutional buyers, the initial purchasers of the Notes (Initial Purchasers). We issued the Notes under an Indenture, dated May 3, 2013. The Notes provide for 7.50% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on May 1 and November 1 of each year. The Notes are secured by a first-priority lien, other than customary permitted liens, on substantially all of our assets, whether now owned or hereafter acquired. In July 2014, we raised $30.0 million non-recourse liablity related to the sale of future royalties.

Table of Contents

Through September 30, 2016, holders of the Notes have converted a total of approximately $83.4 million of the Notes. Cumulatively, through September 30, 2016, we issued a total of approximately 15.7 million shares of common stock in conversion of the principal amount of the Notes and issued an additional 2.2 million shares of common stock and paid approximately $1.7 million cash in settlement of the interest make-whole provision related to the converted Notes.

We believe our current cash resources coupled with increasing revenues from increasing product sales, will be sufficient to finance the Company.

We expect continued profitability in 2016 as we continue to increase sales while also increasing activities and spending to advance our clinical product candidates. We expect significant variability from quarter to quarter in our level of profitability primarily due to variability in R&D expenditures for clinical trials and variability in SG&A expenditures for marketing activities.

On December 17, 2014, the SEC declared effective our registration statement on Form S-3. We have not sold any securities under the registration statement and as of the filing date of this Amended From 10-Q, we are no longer eligible to use the Form S-3 registration statement to sell any securities.

(1) Our commitments for operating leases relate to our lease of fleet vehicles and office and laboratory space as of September 30, 2016.

(2) Relates primarily to agreements and purchase orders with contractors for the conduct of clinical trials, other research and development activities and sales and marketing activities.

(3) This table does not include (a) any milestone payments which may become payable to third parties under license agreements or contractual agreements regarding our clinical trials as the timing and likelihood of such payments are not known, (b) any royalty payments to third parties as the amounts, timing and likelihood of such payments are not known and (c) contracts that are entered into in the ordinary course of business which are not material in the aggregate in any period presented above.

In addition to the above table, we are contractually obligated to allow all royalty payments earned under a licensing agreement with United Therapeutics Corporation to be paid to HC Royalty. Although we have recorded a liability of $30.6 million at September 30, 2016 related to this obligation, it is a non-recourse liability for which we have no obligation to make any payments to HC Royalty. Accordingly, this obligation will have no impact on our liquidity at any time. As a result, the non-recourse liability has not been included in the table above

We have obtained exclusive licenses from third parties for proprietary rights to support the product candidates in our psychiatry portfolio. Under license agreements with Afecta Pharmaceuticals, Inc. (Afecta), we have an exclusive option to evaluate Afecta’s CNS pipeline and to obtain exclusive worldwide rights to selected product candidates, including an exclusive license to SPN-810. We do not owe any future milestone payments for SPN-810. We will be obligated to pay royalties to Afecta based on net sales worldwide of our product candidates in the low-single digits.

We have also entered into a purchase and sale agreement with Rune HealthCare Limited (Rune), where we obtained the exclusive worldwide rights to a product concept from Rune. There are no future milestone payments owing to Rune under this agreement. If we receive approval to market and sell any products based on the Rune product concept for SPN-809 (viloxazine hydrochloride), we will be obligated to pay royalties to Rune based on net sales worldwide in the low-single digits.

Off-Balance Sheet Arrangements

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts.

Recently Issued Accounting Pronouncements

For a discussion of new accounting pronouncements, see Note 2 in the notes to the consolidated financial statements in Part I, Item 1 of this report.

Jumpstart Our Business Startups Act of 2012

The JOBS Act permits an “emerging growth company” such as ours to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have chosen to “opt out” of this provision. As a result, we will continue to comply with new or revised accounting standards as required when they are adopted. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The primary objective of our investment activities is to preserve our capital and to fund operations. We also seek to maximize income from our investments without assuming significant interest rate or default risk. Our exposure to market risk is confined to our cash, cash equivalents, marketable securities and long term marketable securities. As of September 30, 2016, we had unrestricted cash, cash equivalents, marketable securities and long term marketable securities of $147.4 million. We do not engage in any hedging activities against changes in interest rates. Because of the short-term maturities of our cash, cash equivalents and marketable securities, and because typically we hold these securities and our long term marketable securities to maturity, we do not believe that an increase in market rates would have any significant impact on the realized value of our investments. We do not have any currency or other derivative financial instruments other than the interest make-whole payment associated with our Notes.

We engage with a limited number of vendors where we pay for services recorded in currencies other than the U.S. dollars and may be subject to fluctuations in foreign currency rates. We do not hedge our foreign currency exchange rate risk. A hypothetical 10% appreciation in Euro exchange rates against the U.S. dollar from prevailing market rates would have decreased our net income by approximately $4,000 for the three months ended September 30, 2016. Conversely, a hypothetical 10% depreciation in Euro exchange rates against the U.S. dollar from prevailing market rates would have increased our net income by approximately $4,000 for the three months ended September 30, 2016. We do not believe that inflation and changing prices over the three and nine months ended September 30, 2016 and September 30, 2015 had a significant impact on our consolidated results of operations.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO and our CFO, as appropriate, to allow timely decisions regarding required disclosures.

Our management, including the CEO and CFO, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected.

We conducted an evaluation, under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rules 13a-15(b) and 15d-15(b) under the Exchange Act. Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of September 30, 2016 and 2015 due to the material weakness described below.

Table of Contents

In November 2016, management identified a material weakness in internal control over financial reporting. Management’s review revealed that our risk assessment process and our review controls over the accounting for significant, complex, and unusual accounting transactions was deficient, in that these controls were not designed to ensure that sufficient technical accounting expertise was applied to assess and document the appropriate accounting over such transactions. These control deficiencies resulted in a previously reported material misstatement within the Company’s consolidated financial statements. The presence of these control deficiencies created a reasonable possibility that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis. Therefore, we concluded that the deficiencies represented a material weakness in the Company’s internal control over financial reporting and that our internal control over financial reporting was not effective as of September 30, 2016.

Management’s Remediation Initiatives

During 2016, we took action to strengthen our control procedures and risk assessment process regarding the review of the accounting for significant, complex, and unusual transactions. We have engaged, and going forward will continue to engage, expert third party accounting service providers and relevant subject matter experts to supplement the Company’s existing expertise and resources. This will include, amongst other actions, thorough considerations of potential alternative accounting treatment regarding significant, complex, and unusual transactions.

We will continue to devote time and attention to these remediation efforts. As we continue to evaluate and work to improve our controls, management may implement additional measures to enhance the

Table of Contents

remediation plans described above, and will continue to review and make necessary changes to improve the overall design of our controls.

Changes in Internal Control over Financial Reporting

In the first quarter of 2016, we implemented a new financial accounting system. The software package which was selected has been implemented in numerous publicly held manufacturing and service companies within the U.S. It is supported by a major software provider in the U.S.

The primary impetus for this change was to retire a platform that the Company had outgrown and which lacked much of the additional functionality required to support the Company’s expanded operations. We believe incorporating this additional functionality into an upgraded system will provide a stronger base and enhance our overall control environment. The implementation was not made in response to any significant deficiency or material weakness in our internal control over financial reporting.

Management believes the new system has been successfully implemented and is functioning as required.

Other than the changes described above under “Management’s Remediation Initiatives” and the new financial accounting system implementation, during the three months September 30, 2016, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

From time to time and in the ordinary course of business, we are subject to various claims, charges and litigation. We may be required to file infringement claims against third parties for the infringement of our patents. We have filed such claims for infringement of the Orange Book patents listed for our products Oxtellar XR and Trokendi XR.

Supernus Pharmaceuticals, Inc. v. Actavis, Inc., et al., C.A. Nos. 13-4740; 14-1981 (RMB)(JS) (D.N.J.)
Supernus Pharmaceuticals, Inc. v. Actavis, Inc., et al., Appeal No. 2016-1619 (Fed. Cir.)

We received a Paragraph IV Notice Letter against two of our Oxtellar XR Orange Book patents (United States Patent Nos. 7,722,898 and 7,910,131) from generic drug maker Watson Laboratories, Inc.—Florida (WLF) n/k/a Actavis Laboratories FL, Inc. (Actavis Labs FL) on June 26, 2013. On August 7, 2013, we filed a lawsuit against Actavis, Inc., Actavis Labs FL, Actavis Pharma, Inc., Watson Laboratories, Inc., and ANDA, Inc. (collectively Actavis) alleging infringement of United States Patent Nos. 7,722,898 and 7,910,131. We received a second Paragraph IV Notice Letter against a later-issued Oxtellar XR Orange Book Patent (United States Patent No. 8,617,600) on February 20, 2014. On March 28, 2014, we filed a second lawsuit against Actavis alleging infringement of United States Patent No. 8,617,600. We have since listed four additional Orange Book patents: United States Patent Nos. 8,821,930, 9,119,791, 9,351,975, and 9,370,525. Our United States Patent Nos. 7,722,898, 7,910,131, 8,617,600, 8,821,930, 9,119,791, 9,351,975, and 9,370,525 generally cover once-a-day oxcarbazepine formulations and methods of treating seizures using those formulations. The FDA Orange Book lists all seven of our Oxtellar XR patents as expiring on April 13, 2027.

Both Complaints—filed in the U.S. District Court for the District of New Jersey—alleged, inter alia, that Actavis infringed our Oxtellar XR patents by submitting to the FDA an Abbreviated New Drug Application (ANDA) seeking to market a generic version of Oxtellar XR prior to the expiration of our patents. The two cases were consolidated for all purposes on October 8, 2015.

A seven-day bench trial for the consolidated action involving United States Patent Nos. 7,722,898, 7,910,131, and 8,617,600 was held between November 18 and December 4, 2015. On February 5, 2016, the Court issued an opinion and order finding that: (i) Actavis’s ANDA products infringe United States Patent Nos. 7,722,898 and 7,910,131; (ii) Actavis’s ANDA products do not infringe U.S. Patent No. 8,617,600; and (iii) United States Patent Nos. 7,722,898, 7,910,131, and 8,617,600 are not invalid. The Court entered a final judgment on February 18, 2016: (i) enjoining the FDA from approving Actavis’s ANDA before the expiration date of United States Patent Nos. 7,722,898 and 7,910,131; and (ii) enjoining Actavis from commercially manufacturing, using, offering to sell, or selling within the United States, or importing into the United States, Actavis’s ANDA products until the expiration of United States Patent Nos. 7,722,898 and 7,910,131. On February 19, 2016, Actavis filed a Notice of Appeal to the United States Court of Appeals for the Federal Circuit. The parties executed a Partial Settlement Agreement in May 2016 that provided for the dismissal of all appeals, cross-appeals, claims, and counterclaims concerning U.S. Patent Nos. 8,617,600, 8,821,930, and 9,119,791. The appeal with respect to United States Patent Nos. 7,722,898 and 7,910,131 (docketed on February 24, 2016) was argued on December 8, 2016. On December 12, 2016, the United States Court of Appeals for the Federal Circuit affirmed the District Court’s February 18, 2016 Final Judgment.

Supernus Pharmaceuticals, Inc. v. Actavis, Inc., et al., C.A. No. 15-2499 (RMB)(JS) (D.N.J.)

We received a Paragraph IV Notice Letter against United States Patent No. 8,821,930 from Actavis Labs FL on February 21, 2015. On April 7, 2015, we filed a third lawsuit against Actavis alleging infringement of United States Patent No. 8,821,930.

The Complaint—filed in the U.S. District Court for the District of New Jersey—alleged, inter alia, that Actavis infringed United States Patent No. 8,821,930 by submitting to the FDA an ANDA seeking to market a generic version of Oxtellar XR prior to the expiration of United States Patent No. 8,821,930.

The parties executed a Partial Settlement Agreement in May 2016 that provided for the dismissal of both parties’ claims and counterclaims concerning U.S. Patent No. 8,821,930.

Supernus Pharmaceuticals, Inc. v. TWi Pharmaceuticals, Inc., et al., C.A. No. 15-369 (RMB)(JS) (D.N.J.)

We received a Paragraph IV Notice Letter against United States Patent Nos. 7,722,898, 7,910,131, 8,617,600, and 8,821,930 from generic drug maker TWi Pharmaceuticals, Inc. on December 9, 2014. On January 16, 2015, we filed a lawsuit against TWi Pharmaceuticals, Inc. and TWi International LLC (d/b/a TWi Pharmaceuticals USA) (collectively TWi) alleging infringement of United States Patent Nos. 7,722,898, 7,910,131, 8,617,600, and 8,821,930.

The Complaint—filed in the U.S. District Court for the District of New Jersey—alleged, inter alia, that TWi infringed our Oxtellar XR patents by submitting to the FDA an ANDA seeking to market a generic version of Oxtellar XR prior to the expiration of our patents. Filing the Complaint within 45 days of receiving TWi’s Paragraph IV certification notice entitles Supernus to an automatic stay preventing the FDA from approving TWi’s ANDA for 30 months from the date of our receipt of the first Paragraph IV certification notice. On February 13, 2015, TWi answered the Complaint and denied the substantive allegations of the Complaint. TWi also asserted Counterclaims seeking declaratory judgments of non-infringement and invalidity of United States Patent Nos. 7,722,898 and 7,910,131. On March 20, 2015, we filed our Reply, denying the substantive allegations of those Counterclaims.

The parties have completed fact and expert discovery, and are preparing final joint pretrial submissions. The District Court has set March 27, 2017 as the trial start date.

Supernus Pharmaceuticals, Inc. v. Actavis, Inc., et al., C.A. No. 15-8342 (RMB)(JS) (D.N.J.)

We received a Paragraph IV Notice Letter against United States Patent No. 9,119,791 from Actavis Labs FL on October 15, 2015. On November 25, 2015, we filed a fourth lawsuit against Actavis alleging infringement of United States Patent No. 9,119,791.

The Complaint—filed in the U.S. District Court for the District of New Jersey—alleged, inter alia, that Actavis infringed United States Patent No. 9,119,791 by submitting to the FDA an ANDA seeking to market a generic version of Oxtellar XR prior to the expiration of United States Patent No. 9,119,791. On January 29, 2016, Actavis answered the Complaint, denying the substantive allegations of that Complaint. Actavis Labs FL also asserted Counterclaims seeking declaratory judgments of non-infringement and invalidity of United States Patent No. 9,119,791. On March 4, 2016, we filed our Reply, denying the substantive allegations of those Counterclaims.

The parties executed a Partial Settlement Agreement in May 2016 that provided for the dismissal of both parties’ claims and counterclaims concerning U.S. Patent No. 9,119,791.

Supernus Pharmaceuticals, Inc. v. Actavis, Inc., C.A. No. 14-6102 (SDW)(LDW) (D.N.J.)

We received three Paragraph IV Notice Letters against six Trokendi XR Orange Book patents, namely United States Patent Nos. 8,298,576, 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989 from generic drug maker Actavis Laboratories FL, Inc. These patents cover once-a-day topiramate formulations and methods of treating seizures using those formulations. On October 1, 2014, we initiated a lawsuit against Actavis; the lawsuit alleges infringement of the Trokendi XR Orange Book patents. The FDA Orange Book currently lists United States Patent No. 8,298,576 as expiring on April 4, 2028 and United States Patent Nos. 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989 as expiring on November 16, 2027.

This action for patent infringement—filed in the U.S. District Court for the District of New Jersey—alleges that Actavis infringed the Trokendi XR patents by, inter alia, submitting to the FDA an ANDA seeking to market a generic version of Trokendi XR prior to the expiration of these patents. Actavis answered these allegations with affirmative defenses and counterclaims of noninfringement and invalidity of the patents in suit. Filing its October 1, 2014 Complaint within 45 days of receiving the first of three Actavis Laboratories FL, Inc. Paragraph IV Notice Letters entitles Supernus to an automatic stay preventing the FDA from approving Actavis’s ANDA for 30 months from the date of our receipt of such Notice Letter.

This case has been consolidated for pretrial purposes with two other actions pending in the District of New Jersey concerning infringement of the Trokendi XR Orange Book patents, those actions being C.A. No. 14-7272 (against Zydus Pharmaceuticals (USA) Inc. and Cadila Healthcare Limited) and C.A. No. 15-326 (against Par Pharmaceutical Companies, Inc. and Par Pharmaceutical, Inc.). The Company has since entered into a settlement agreement with Par (see below). A Rule 16 scheduling conference was held on April 14, 2015. The Court issued a Scheduling Order on May 22, 2015, which was amended several times, most recently on July 15, 2016. The Court issued its Markman Opinion and Order on March 9, 2016. The Court adopted Supernus’s definitions of five of the seven disputed terms, and did not adopt any of Actavis’s definitions. Fact discovery ended on May 4, 2016. The case is proceeding through expert discovery. The Court’s Amended Scheduling Order states that no summary judgment motions shall be filed. No date has been set for trial.

Supernus Pharmaceuticals, Inc. v. Zydus Pharmaceuticals (USA) Inc., C.A. No. 14-7272 (SDW)(LDW) (D.N.J.)

We received three Paragraph IV Notice Letters against six Trokendi XR Orange Book patents, namely United States Patent Nos. 8,298,576, 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989 from generic drug maker Zydus Pharmaceuticals (USA) Inc. These patents cover once-a-day topiramate formulations and methods of treating seizures using those formulations. On November 21, 2014, we initiated a lawsuit against Zydus Pharmaceuticals (USA) Inc. and Cadila Healthcare Limited (collectively Zydus); the lawsuit alleges infringement of the Trokendi XR Orange Book patents. The FDA Orange Book currently lists United States Patent No. 8,298,576 as expiring on April 4, 2028 and United States Patent Nos. 8,298,580, 8,663,683, 8,877,248, 8,889,191 and 8,992,989 as expiring on November 16, 2027.

This action for patent infringement—filed in the U.S. District Court for the District of New Jersey—alleges that Zydus infringed the Trokendi XR patents by, inter alia, submitting to the FDA an ANDA seeking to market a generic version of Trokendi XR prior to the expiration of these patents. Zydus answered these allegations with affirmative defenses and counterclaims of noninfringement and invalidity of the patents in suit. Filing its November 21, 2014 Complaint within 45 days of receiving the first of three Paragraph IV Notice Letters from Zydus Pharmaceuticals (USA) Inc. entitles Supernus to an automatic stay preventing the FDA from approving Zydus’s ANDA for 30 months from the date of our receipt of such Notice Letter.

Supernus Pharmaceuticals, Inc. v. Par Pharmaceutical Companies, Inc., C.A. No. 15-326 (SDW)(LDW) (D.N.J.)

We received three Paragraph IV Notice Letters against six Trokendi XR Orange Book patents, namely United States Patent Nos. 8,298,576, 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989 from generic drug maker Par Pharmaceutical, Inc. These patents cover once-a-day topiramate formulations and methods of treating seizures using those formulations. On January 16, 2015, we initiated a lawsuit against Par; the lawsuit alleges infringement of the Trokendi XR Orange Book patents. The FDA Orange Book currently lists United States Patent No. 8,298,576 as expiring on April 4, 2028 and United States Patent Nos. 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989 as expiring on November 16, 2027.

This action for patent infringement—filed in the U.S. District Court for the District of New Jersey—alleges that Par infringed the Trokendi XR patents by, inter alia, submitting to the FDA an ANDA seeking to market a generic version of Trokendi XR prior to the expiration of these patents. Par answered these allegations with affirmative defenses and counterclaims of noninfringement and invalidity of the patents in suit. Filing its January 16, 2015 Complaint within 45 days of receiving the first of three Paragraph IV Notice Letters from Par Pharmaceutical, Inc. entitles Supernus to an automatic stay preventing the FDA from approving Par’s ANDA for 30 months from the date of our receipt of such Notice Letter.

The Company announced on October 15, 2015 that it has entered into a settlement agreement with Par regarding this case. The settlement permits Par to begin selling a generic version of Trokendi XR on April 1, 2025, or earlier under certain circumstances. The agreement is subject to a consent judgment that was entered by the U.S. District Court for the District of New Jersey. In the consent judgment, Par acknowledges that the Orange Book-listed patents for Trokendi XR owned by Supernus, namely United States Patent Nos. 8,298,576, 8,298,580, 8,663,683, 8,877,248, 8,889,191, and 8,992,989, are valid and enforceable with respect to Par’s ANDA product, and would be infringed by Par’s ANDA product. The agreement has been submitted to the applicable governmental agencies.

Item 1A. Risk Factors

Any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our condensed consolidated financial statements and related notes, and the additional information in the other reports we file with the Securities and Exchange Commission along with the risks described in our Annual Report on Form 10-K/A for the year ended December 31, 2015.
