Supernus Pharmaceuticals, Inc.
Notes to Consolidated Financial Statements

For the Three and Nine months ended September 30, 2014 and 2013
(unaudited)

1. Organization and Business

Supernus Pharmaceuticals, Inc. (the Company) is a specialty pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system 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.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc. and Supernus Europe Ltd. These are 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, 2013.

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, 2014 are not necessarily indicative of the Company’s future financial results.

Accounts Receivable, net

Accounts receivable are reported in the consolidated balance sheets at outstanding amounts, less allowances for doubtful accounts and prompt pay 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. No accounts have been written off in 2014 or 2013. No allowance for uncollectible receivables is recorded at September 30, 2014 or December 31, 2013. The Company recorded an allowance of approximately $0.3 million and $0.1 million for expected prompt-pay discounts as of September 30, 2014 and December 31, 2013, respectively.

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 (collectively, “sales deductions”) as well as estimated product returns.

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. Beginning in the fourth quarter of 2013, the Company began recognizing revenue for Oxtellar XR, net of estimated sales deductions, at the time of shipment to wholesalers. Beginning in the second quarter of 2014, the Company began recognizing revenue for Trokendi XR, net of

Table of Contents

estimated sales deductions, at the time of shipment to wholesalers. Prior to these changes in accounting estimate, the Company recognized revenue once delivery had occurred and all sales deductions were known or reasonably estimated.

In the third quarter of 2014, the Company recognized $30.0 million in revenue from a royalty agreement related to HealthCare Royalty Partners III, L.P.’s purchase of certain of the Company’s rights under the Royalty Interest Acquisition Agreement with United Therapeutics Corporation related to the commercialization of Orenitram. The Company determined to recognize this revenue immediately because (1) the executed contract constituted persuasive evidence of an arrangement, (2) the delivery of the license occurred and the Company has no current or future performance obligations, (3) the total consideration for the license amendment was fixed and known at the time of its execution and there were no rights of return, and (4) the cash was received and is non-refundable.

Milestone Payments

Milestone payments on licensing agreements are recognized as revenue when the collaborative partner acknowledges completion of the milestone and substantive effort 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 zero and $2.0 million in milestone revenue during the three and nine months ended September 30, 2014, respectively, and no milestone revenue during the three and nine months ended September 30, 2013.

Income Taxes

During the nine months ended September 30, 2014, the Company had pre-tax net income of $15.5 million. The provision for Federal and state income taxes related to such pre-tax net income has been offset by the utilization of available net operating loss carryovers. Accordingly, the Company reduced its valuation allowance against its deferred tax assets and recognized an income tax benefit in an amount equal to the provision for income taxes.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 will eliminate transaction- and industry-specific revenue recognition guidance under current 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. Early adoption is not permitted. 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.

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-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 or liabilities 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).

Table of Contents

· 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:

Liabilities:
Derivative liabilities	$	12,644	$	—	$	—	$	12,644

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 money market funds and U.S. Treasury and government agency debt securities with quoted prices in active markets.

Level 2 assets include mutual funds in which the SERP (Supplemental Executive Retirement Plan) assets are invested, 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.

Table of Contents

Level 3 liabilities include the fair market value of the interest make-whole liability associated with the Company’s 7.50% Convertible Senior Secured Notes due 2019 (the Notes) and the outstanding warrants to purchase Common Stock, which are recorded as derivative liabilities. The fair value of the common stock warrant liability was calculated using a Monte-Carlo simulation with a Black-Scholes model with the following assumptions as of September 30, 2014:

Exercise Price		$4 - $5 per share
Volatility		50%
Stock Price as of September 30, 2014		$8.69 per share
Term		6.3 - 7.2 years
Dividend Yield		0.0%
Risk-Free Rate		2.03% - 2.18%

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, 2014:

Volatility		45%
Stock Price as of September 30, 2014		$8.69 per share
Credit Spread		1254 bps
Term		2.6 years
Dividend Yield		0.0%

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

Changes in the fair value of the warrants and 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, 2013 and September 30, 2014 that are included in the Non-Current Liabilities section of the Consolidated Balance Sheets, in thousands:

	Nine Months ended
	September 30, 2014
	(unaudited)

Balance at December 31, 2013	$	12,644
Changes in fair value of derivative liabilities included in earnings	(2,115		)
Reduction due to conversion of debt to equity	(3,271		)
Balance at September 30, 2014	$	7,258

The carrying value, face value and estimated fair value of the Notes was approximately $26.5 million, $36.1 million and $65.3 million, respectively, as of September 30, 2014. 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. These items have been 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.

10. Income (Loss) Per Share

Basic income/ (loss) per common share is determined by dividing income/ (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted income/ (loss) per share is computed by dividing the income/ (loss) 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, SAR, potential Employee Stock Purchase Plan (ESPP) awards and warrants, and the if-converted method (which reflects a calculated loss on debt extinguishment) is used to determine the dilutive effect of the Company’s Notes. The following common stock equivalents were excluded in the calculation of diluted loss per share because their effect would be anti-dilutive for the periods ended September 30, 2014 and 2013:

Overview

We are a specialty pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system, or CNS, diseases. In 2013, we launched Oxtellar XR (extended-release oxcarbazepine) and Trokendi XR (extended-release topiramate), our two novel treatments for epilepsy.

In addition, we are developing multiple product candidates in psychiatry to address the large market opportunity in the treatment of attention deficit hyperactivity disorder, or ADHD, including the unmet clinical need in impulsive aggression in patients who have ADHD.

Marketed Products. Oxtellar XR and Trokendi XR are the first once-daily extended release oxcarbazepine and topiramate products, respectively, indicated for epilepsy in the U.S. market. The products are differentiated from the immediate release products by offering once-daily dosing and unique pharmacokinetic profiles that can be very important for patients with epilepsy. A once-daily dosing regimen has been shown to improve compliance allowing patients to more completely benefit from their medications, and the unique smooth and steady pharmacokinetic profiles reduce the blood level fluctuations that are associated with immediate release products and their symptomatic side effects. To date, we have received positive feedback from patients and physicians regarding the clinical benefits and outcomes they are experiencing with our products, and no new safety signals have arisen.

We expect the number of prescriptions filled for Oxtellar XR and Trokendi XR to increase throughout 2014 and in later years. Data from Wolters-Kluwer/Symphony show 57,776 prescriptions filled for the three months ended September 30, 2014, representing a growth of 26.1% as compared to the three months ended June 30, 2014, which totaled 45,813 prescriptions filled.

Total prescriptions, as reported by an alternative source of prescription data, IMS Health, or IMS, (aggregating Trokendi XR and Oxtellar XR), grew from 43,207 during the three months ended June 30, 2014 to 56,261 during the three months ended September 30, 2014, an increase of 30.2%.

We have incurred losses from ongoing operations in 2013 and, excluding our licensing revenues, the first nine months of 2014 as part of our investment in and commitment to successful product launches for Oxtellar XR and Trokendi XR as well as expenditures to develop our product candidates. We expect to be cash flow break even from ongoing operations by year-end 2014, and profitable in 2015 and beyond.

Table of Contents

We believe our working capital and long term marketable securities balance of $96.6 million as of September 30, 2014, along with increased revenues from increasing product sales, will be sufficient to finance the Company. Beyond 2014, we expect the business to be cash flow positive.

We are progressing with our Phase IV post-marketing commitments for Oxtellar XR and Trokendi XR. The work we are doing to meet the Food and Drug Administration, or FDA, commitments may also have applicability in life-cycle management.

We entered into a Royalty Interest Acquisition Agreement in July 2014 with HealthCare Royalty Partners III, L.P., or HC Royalty. Pursuant to this Agreement, HC Royalty made a $30.0 million cash payment to the Company in consideration for acquiring from the Company certain royalty and milestone rights related to the commercialization of Orenitram (treprostinil) Extended-Release Tablets by the Company’s partner United Therapeutics Corporation. We will retain full ownership of the royalty rights after a certain threshold has been reached per the terms of the Agreement.

We have received several Paragraph IV Notice Letters from various third-parties. (See Part II, Item 1, Legal Proceedings for additional information.)

We received a Paragraph IV Notice Letter on August 20, 2014 from generic drug maker Actavis Laboratories FL, Inc. against United States Patent Nos. 8,298,576, 8,298,580, and 8,663,683, our three Trokendi XR Orange Book patents that cover once-a-day topiramate formulations and methods of treating seizures using those formulations. On October 1, 2014, we filed a lawsuit in the United States District Court for the District of New Jersey against Actavis, Inc., Actavis Laboratories FL, Inc., Actavis plc, Actavis Pharma, Inc., Watson Laboratories, Inc., and Anda, Inc. (collectively “Actavis”) for infringement of these three patents.

We received a Paragraph IV Notice Letter on October 13, 2014 against our three Trokendi XR Orange Book patents from generic drug maker Zydus Pharmaceuticals (USA) Inc. We are reviewing the details of this Notice Letter and intend to vigorously enforce our intellectual property rights relating to Trokendi XR.

Product Candidates. We are developing SPN-810 (molindone hydrochloride) as a treatment for impulsive aggression in patients who have attention deficit hyperactivity disorder, or ADHD. We completed a Phase IIb trial in 2012 demonstrating both safety and efficacy. During the third quarter of 2014, we met with the FDA to discuss commercial manufacturing requirements. In preparation for starting Phase III clinical trials in 2015, we have conducted technology transfer and completed scale up at the commercial manufacturing site. We expect to commence patient dosing in the second half of 2015.

Based on ongoing dialogue, and in close collaboration with the FDA, we have created a new and specific outcome and assessments scale for use in this first-in class development program for the treatment of impulsive aggression in patients with ADHD. We completed a clinical trial to validate this scale during 2014, and are analyzing the results.

The Company has an End of Phase II clinical meeting scheduled with the FDA during December.

The Phase III program will undergo a Special Protocol Assessment. The FDA has granted fast track designation for SPN-810 for the treatment of impulsive aggression in ADHD. Fast track designation is for products that are being investigated for treatment of serious conditions, and for which nonclinical or clinical data suggest that they may address an unmet medical need. Whether a disease or condition is serious is a matter of clinical judgment, based on its impact on such factors as survival, day-to-day functioning, or the likelihood that the disease, if left untreated, will progress from a less severe condition to a more serious one. The fast track designation allows for more frequent interactions between the FDA and us, allows for the early submission of some sections of the marketing application, and carries the potential for an expedited review category for the New Drug Application.

In addition to SPN-810, we are developing SPN-812 for the treatment of ADHD. In the second quarter of 2014, we initiated and completed a pharmacokinetics study for extended release formulations for SPN-812. The study was successful and we have selected an extended release formulation that will be the basis of the product. We expect to start the first pivotal trial during the second half of 2015. In addition, both pipeline programs continue to move forward with the customary animal toxicology studies, including carcinogenicity programs.

We expect to incur significant research and development expenses related to the continued development of each of our product candidates.

Critical Accounting Policies and the Use of Estimates

The significant accounting policies and basis of presentation for our consolidated financial statements are described in Note 2 “Summary of Significant Accounting Policies.” The preparation of our financial statements in accordance with U.S. generally accepted accounting principles, or 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 in our financial statements. Actual results could differ from those estimates.

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

Inventories

We carry inventories at the lower of cost or market using the first-in, first-out method. Inventory values include materials, labor, and direct and indirect overhead. Inventory is evaluated for impairment through consideration of factors such as net realizable value, obsolescence and expiry. The value of our inventories does not exceed either replacement cost or net realizable value. We believe Oxtellar XR and Trokendi XR have limited risk of obsolescence or expiry based on current demand, our projection for future demand, and product dating. We provide reserves and allowances for items we consider to be obsolete.

Revenue Recognition

Revenue from product sales is recognized when persuasive evidence of an arrangement exists; delivery has occurred and title of 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 (collectively, “sales deductions”) as well as estimated product returns.

Our products are distributed through wholesalers and pharmaceutical distributors. Each of these wholesalers and distributors will take title and ownership of the product upon physical receipt of the product and then distribute our products to pharmacies. Beginning in the fourth quarter of 2013, we began recognizing revenue for Oxtellar XR, net of estimated sales deductions, at the time of shipment to wholesalers. Beginning in the second quarter of 2014, we began recognizing revenue for Trokendi XR, net of estimated sales deductions, at the time of shipment to wholesalers.

In the third quarter of 2014, the Company recognized $30.0 million in revenue from a royalty agreement related to HealthCare Royalty Partners III, L.P.’s purchase of certain of the Company’s rights under the license agreement with United Therapeutics Corporation related to the commercialization of Orenitram. The Company determined to recognize this revenue immediately because (1) the executed contract constituted persuasive evidence of an arrangement, (2) the delivery of the license occurred and the Company has no current or future performance obligations, (3) the total consideration for the license amendment was fixed and known at the time of its execution and there were no rights of return, and (4) the cash was received and is non-refundable.

Net Product Sales. Our net product sales of $22.5 million for the three months ended September 30, 2014 are based on $7.2 million of revenue from shipments of Oxtellar XR to distributors, less estimates for discounts, rebates, other sales deductions and returns, and $15.3 million of revenue from shipments of Trokendi XR to distributors, less estimates for discounts, rebates, other sales deductions and returns.

We launched Oxtellar XR in February 2013 and recognized $1.1 million of revenue in the third quarter of 2013 based on prescriptions filled at the patient level during the second quarter of 2013 for which all sales deductions had become known.

Revenue from Royalty Agreement. The revenue for the three month period ended September 30, 2014 resulted from the Royalty Interest Acquisition Agreement that we entered into with HC Royalty for Orenitram, which is marketed by United Therapeutics Corporation. We received $30.0 million upon execution of that Agreement.

Research and Development Expense. Research and development expenses during the three months ended September 30, 2014 were $4.7 million as compared to $3.8 million for the three months ended September 30, 2013, an increase of $0.9 million or 23.2%. This increase is due to preclinical and clinical trials and manufacturing scale up for both of our product candidates, SPN-810 and SPN-812.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses were $17.3 million during the three months ended September 30, 2014 as compared to $14.6 million for the three months ended September 30, 2013, an increase of $2.7 million or 18.6%. This increase was mainly due to an increase in marketing expenses such as sample distribution and expenses related to the increase in compensation and travel due to the expansion of our sales force to support the growth of Oxtellar XR and Trokendi XR.

Table of Contents

Interest Expense. Interest expense was $1.3 million during the three months ended September 30, 2014 as compared to $2.9 million for the three months ended September 30, 2013. The decrease of $1.6 million was primarily due to a decrease in the interest on the aggregate principal amount of 7.50% Convertible Senior Secured Notes due 2019, or the Notes, which were issued in May 2013. Through September 30, 2014, approximately $53.9 million of the original $90.0 million of the Notes has been converted into equity.

Changes in Fair Value of Derivative Liability. During the three months ended September 30, 2014, we recognized a non-cash credit of $0.8 million associated with the interest make-whole derivative liability related to our Notes. The change in fair value, which reduces interest expense in periods subsequent to conversion, is primarily due to the passage of time and because our stock price remains above the $5.30 conversion price. We recognized a non-cash charge of $4.1 million associated with the interest make-whole derivative during the third quarter of 2013, primarily due to the effect of the increase in our stock price on the valuation of its derivative liability.

Loss on Extinguishment of Debt. During the three months ended September 30, 2014, we recognized a non-cash charge of $0.9 million related to the conversion of $3.7 million of our Notes.

Net Income (Loss). We realized net income of $27.9 million during the three months ended September 30, 2014 as compared to a net loss of $24.1 million during the three months ended September 30, 2013, an increase of $52.0 million. This change was due primarily to the revenue generated from our two commercial products, Oxtellar XR and Trokendi XR, and $30 million in revenue as a result of the HC Royalty Agreement.

Net Product Sales. Our net product sales of $59.1 million for the nine months ended September 30, 2014 are based on $17.1 million of revenue from shipments of Oxtellar XR to distributors, less estimates for discounts, rebates, other sales deductions and returns, and $42.0 million of revenue from shipments of Trokendi XR to distributors, less estimates for discounts, rebates, other sales deductions and returns.

Table of Contents

We launched Oxtellar XR in February 2013 and recognized $1.3 million of revenue in the nine months ended September 30, 2013 based on prescriptions filled at the patient level during the first and second quarters of 2013 for which all sales deductions had become known.

Revenue for Trokendi XR of $42.0 million includes revenue from prescriptions filled at the patient level during the fourth quarter of 2013 ($4.1 million) for which sales deductions became known in 2014. We transitioned to contemporaneously recognizing revenue upon shipment of finished product to wholesalers, net of allowances for estimated sales deductions and returns in the second quarter of 2014.

Revenue from Royalty Agreement. The revenue for the nine month period ended September 30, 2014 resulted from the Royalty Interest Acquisition Agreement that we entered into with HC Royalty for Orenitram, which is marketed by United Therapeutics Corporation. We received $30.0 million upon execution of that Agreement.

Licensing Revenue. The licensing revenue for the nine month period ended September 30, 2014 consisted primarily of the United Therapeutics Corporation milestone payment of $2 million under their license agreement with Supernus.

Research and Development Expense. Research and development expenses during the nine months ended September 30, 2014 were $13.8 million as compared to $11.8 million for the nine months ended September 30, 2013, an increase of $2.0 million or 16.6%. This increase is due to preclinical and clinical trials and manufacturing scale up for both of our product candidates, SPN-810 and SPN-812.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses were $54.5 million during the nine months ended September 30, 2014 as compared to $40.4 million for the nine months ended September 30, 2013, an increase of $14.1 million or 34.9%. This increase was mainly due to the increase in compensation and travel due to the expansion of our sales force during the nine months ended September 30, 2014 from 90 sales representatives in 2013 to more than 150 sales representatives in 2014, and an increase in marketing expenses such as sample distribution to support the growth of Oxtellar XR and Trokendi XR.

Interest Expense. Interest expense was $3.8 million during the nine months ended September 30, 2014 as compared to $5.7 million for the nine months ended September 30, 2013. The decrease of $1.9 million was primarily due to interest relating to the $90.0 million aggregate principal amount of Notes which were issued in May 2013. Through September 30, 2014, approximately $53.9 million of Notes were converted into equity, which reduces interest expense in the periods subsequent to conversions.

Changes in Fair Value of Derivative Liability. During the nine months ended September 30, 2014, we recognized a non-cash credit of $2.1 million associated with the interest make-whole derivative liability related to our Notes. This credit is primarily due to the passage of time and because our stock price remains above the $5.30 conversion price. We recognized a non-cash charge of $12.7 million associated with the interest make-whole derivative during the nine months ended September 30, 2013, due primarily to the effect of the increase in our stock price on the valuation of its derivative liability.

Loss on Extinguishment of Debt. During the nine months ended September 30, 2014, we recognized a non-cash charge of $2.6 million related to the conversion of $13.4 million of our Notes. During the nine months ended September 30, 2013, we incurred a loss of $1.2 million on extinguishment of our secured credit facility.

Net Loss. We realized net income of $15.5 million during the nine months ended September 30, 2014 as compared to a net loss of $69.9 million during the nine months ended September 30, 2013, an increase of $85.4 million. This increase in net income was primarily due to the revenue generated from our two commercial products, Oxtellar XR and Trokendi XR, and $30 million in revenue associated with the HC Royalty Agreement, offset by expenses incurred associated with the hiring of our sales force as well as an increase in marketing expenditures associated with ongoing support of Oxtellar XR and Trokendi XR.

Liquidity and Capital Resources

Our working capital at September 30, 2014 was $80.8 million, an increase of $10.0 million compared to our working capital of $70.8 million at December 31, 2013. This increase was primarily attributable to the increase in accounts receivable related to increased sales of both Oxtellar XR and Trokendi XR.

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 research and development efforts, primarily related to development of SPN-810 and SPN-812 as we continue to advance these clinical programs.

Table of Contents

In July 2014, we entered into a Royalty Interest Acquisition Agreement with HealthCare Royalty Partners III, L.P., or HC Royalty. Pursuant to this Agreement, HC Royalty paid us $30.0 million in consideration for acquiring certain royalty and milestone rights related to the commercialization of Orenitram (treprostinil) Extended-Release Tablets by our partner United Therapeutics Corporation. We will retain full ownership of the royalty rights after a certain threshold has been reached per the terms of the Agreement.

In addition to revenues, we have historically financed our business through the sale of our debt and equity securities. On May 3, 2013, we issued $90.0 million aggregate principal amount of Notes. We issued the Notes under an Indenture, dated May 3, 2013, or the Indenture, that we entered into with U.S. Bank National Association, as Trustee and Collateral Agent.

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, beginning on November 1, 2013. Interest will accrue on the Notes from and including May 3, 2013 and the Notes will mature on May 1, 2019, unless earlier converted, redeemed or repurchased by the Company. The Notes are secured by a first-priority lien, other than customary permitted liens, on substantially all of our and our domestic subsidiaries’ assets, whether now owned or hereafter acquired. For a full description of the Notes and the Indenture, see Note 8 to the Consolidated Financial Statements included in Part II, Item 8 of Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 21, 2014.

Through September 30, 2014, holders of the Notes have converted a total of approximately $53.9 million of the Notes. Cumulatively, through September 30, 2014, we issued a total of approximately 10.2 million shares of common stock in conversion of the principal amount of the Notes and issued an additional 1.7 million shares of common stock and paid approximately $1.7 million cash in settlement of interest make-whole provision related to the converted Notes.

We believe our current working capital and long term marketable securities, along with increased revenues from increasing product sales, will be sufficient to finance the Company. We anticipate achieving cash flow break even by year end and being profitable in 2015.

Operating Activities

Net cash used in operating activities is comprised of two components; cash used to fund operating loss and cash used/provided by changes in working capital. Results for the nine months ended September 30, 2014 and September 30, 2013 are summarized below, in thousands:

	Nine Months ended September 30,						Increase
	2014			2013			(decrease)

Net cash provided by (used in) operating activities	$	739		$	(48,528	)

The decrease in net cash used in operating activities is primarily driven by increased revenue for Trokendi XR and Oxtellar XR offset by increases in sales and marketing expenditures associated with the commercialization of these products in 2014.

The changes in certain operating assets and liabilities are, in thousands:

Investing Activities

Our investing activities are principally driven by cash provided by our financing activities. We invest excess cash in accordance with our investment policy. Marketable securities consist of investments which generally mature in fifteen months or less, including U.S. Treasury and various government agency debt securities, as well as investment grade securities in industrial and financial institutions. Fluctuations in investing activities between periods relate exclusively to the timing of marketable security purchases and the related maturities of these securities.

Net cash provided by investing activities for the nine months ended September 30, 2014 of $3.8 million related to marketable securities decreasing by $7.4 million offset by the increase in capitalized patent defense costs of $3.1 million and property and equipment purchases of $0.5 million. Cash used in investing activities for the nine months ended September 30, 2013 of $33.0 million related to the increase in marketable securities of $31.3 million, property and equipment purchases of $1.4 million and $0.3 million in patent defense costs.

Table of Contents

Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2014 was $0.3 million, primarily the result of proceeds received from stock option exercises. For the nine months ended September 30, 2013, net cash provided of $64.2 million consisted of proceeds from the issuance of the Notes of $90.0 million and $2.1 million from issuance of common stock, offset by $24.3 million in repayment of secured notes payable and payment of the related financing costs and $3.6 million upon issuance of common stock.

Off-Balance Sheet Arrangements

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as 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.

Recent Accounting Pronouncements

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 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 to fund operations. We also seek to maximize income from our investments without assuming significant risk. Our exposure to market risk is confined to our cash, cash equivalents, marketable securities and long term marketable securities. As of September 30, 2014, we had unrestricted cash, cash equivalents, marketable securities and long term marketable securities of $88.3 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 we hold these 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 outstanding warrants to purchase common stock and the interest make-whole payment associated with our Notes.

We contract with contract research organizations and investigational sites globally. We may be subject to fluctuations in foreign currency rates in connection with these agreements, primarily with respect to Euro denominated contracts. 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 increased our net loss by approximately $4,000 for the three months ended September 30, 2014. Conversely, a hypothetical 10% depreciation in Euro exchange rates against the U.S. dollar from prevailing market rates would have decreased our net loss by approximately $4,000 for the three months ended September 30, 2014. We do not believe that inflation and changing prices over the three and nine months ended September 30, 2014 and 2013 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 Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

We conducted an evaluation, and under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, 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 Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2014.

Our management, including the Chief Executive Officer and Chief Financial Officer, 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.

Changes in Internal Control over Financial Reporting

There have been no significant changes in our internal control over financial reporting during the three months ended September 30, 2014, that have 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.

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., WLF n/k/a 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 our 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 a fourth patent, United States Patent No. Our United States Patent Nos. 7,722,898, 7,910,131, 8,617,600, and 8,821,930 generally cover once-a-day oxcarbazepine formulations and methods of treating seizures using those formulations. The FDA Orange Book lists all four 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—allege, 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. Filing its August 7, 2013 Complaint within 45 days of receiving Actavis’s Paragraph IV certification notice entitles Supernus to an automatic stay preventing the FDA from approving Actavis’s ANDA for 30 months from the date of our receipt of the first Paragraph IV certification notice. On September 25, 2013, Actavis answered the August 7, 2013 complaint, denying the substantive allegations of that Complaint. One defendant, WLF n/k/a Actavis Labs FL, asserted Counterclaims, seeking declaratory judgments of non-infringement and invalidity of United States Patent Nos. 7,722,898 and 7,910,131. On October 30, 2013, we filed its Reply, denying the substantive allegations of those Counterclaims. On April 30, 2014, Actavis answered the March 28, 2014 complaint, denying the substantive allegations of that Complaint. WLF n/k/a Actavis Labs FL also asserted Counterclaims seeking declaratory judgments of non-infringement and invalidity of United Sates Patent No. 8,617,600. On June 4, 2014, we filed our Reply, denying the substantive allegations of those Counterclaims.

On June 4, 2014, the District Court issued a consolidated scheduling order for both cases. This consolidated case is in its early stages and discovery is proceeding.

We received a Paragraph IV Notice Letter against three Trokendi XR Orange Book patents (United States Patent Nos. 8,298,576; 8,298,580; and 8,663,683) from generic drug maker Actavis Laboratories FL, Inc. on August 20, 2014. On October 1, 2014, we filed a lawsuit against Actavis, Inc.; Actavis Laboratories FL, Inc.; Actavis plc; Actavis Pharma, Inc.; Watson Laboratories, Inc.; and Anda, Inc. (collectively “Actavis”) alleging infringement of United States Patent Nos. 8,298,576; 8,298,580; and 8,663,683. Our United States Patent Nos. 8,298,576; 8,298,580; and 8,663,683 cover once-a-day topiramate formulations and methods of treating seizures using those formulations. The FDA Orange Book currently lists U.S. Patent No. 8,298,576 as expiring on March 18, 2029 and U.S. Patent Nos. 8,298,580 and 8,663,683 as expiring on November 16, 2027.

The Complaint—filed in the U.S. District Court for the District of New Jersey—alleges, inter alia, that Actavis infringed our Trokendi XR patents by submitting to the FDA an ANDA seeking to market a generic version of Trokendi XR prior to the expiration of our patents. Filing its October 1, 2014 Complaint within 45 days of receiving Actavis’s Paragraph IV certification notice entitles Supernus to an automatic stay preventing the FDA from approving Actavis’s ANDA for 30 months from the date of our receipt of Actavis’s Paragraph IV certification notice.

We received a Paragraph IV Notice Letter against three Trokendi XR Orange Book patents (United States Patent Nos. 8,298,576; 8,298,580; and 8,663,683) from generic drug maker Zydus Pharmaceuticals (USA) Inc. on or about October 13, 2014. We are currently reviewing the details of this Notice Letter and will continue to vigorously enforce our intellectual property rights relating to Trokendi XR.

Item 1A. Risk Factors

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

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(a) Sales of Unregistered Securities.

During the three months ended September 30, 2014, the Company granted options to employees to purchase an aggregate of 15,900 shares of common stock at an exercise price of $8.36 per share. The options are exercisable for a period of ten years from the grant date. These issuances were exempt from registration in reliance on Section 4(a)(2) of the Securities Act as transactions not involving any public offering.
