SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements related to present facts or current conditions or historical facts, contained in this Quarterly Report on Form 10-Q, including statements regarding our strategy, future operations, future financial position, projected costs, potential indications for our drug product candidates, expectations regarding the development of our drug product candidates and the launch of our consumer product, the expected timing for the reporting of data from ongoing and future studies, prospects, plans and objectives of management, are forward looking statements. The words "anticipate," "believe," "estimate," "expect," "intend," "may," "plan," "predict," "project," "target," "potential," "will," "would," "could," "should," "continue" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

Forward-looking statements are not guarantees of future performance and our actual results could differ materially from the results discussed in the forward-looking statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, the status, timing, costs, results and interpretation of our clinical studies; the uncertainties inherent in conducting clinical studies; results from our ongoing and planned preclinical development; expectations of our ability to make regulatory filings and obtain and maintain regulatory approvals; our ability to develop and commercialize our consumer products; anticipated positioning and attributes of our consumer products; results of early clinical studies as indicative of the results of future trials; availability of funding sufficient for our foreseeable and unforeseeable operating expenses and capital expenditure requirements; other matters that could affect the availability or commercial potential of our consumer or drug product candidates; the inherent uncertainties associated with intellectual property; and other factors discussed in this Quarterly Report on Form 10-Q, our Annual Report on Form 10-K and other filings with the Securities and Exchange Commission, or SEC.

As a result of these and other factors, we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. We do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

FLEX PHARMA, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
1. Organization and operations
The Company
Flex Pharma, Inc. (the "Company") is a biotechnology company that is developing innovative and proprietary treatments for nocturnal leg cramps, muscle cramps and spasms associated with severe neuromuscular conditions, and exercise-associated muscle cramps. The Company's product candidates are based on the potential mechanism of action described as Chemical Neuro Stimulation, which is the process by which a small molecule chemical signal, acting topically, induces a neuronal sensory signal that produces a beneficial effect. The Company's product candidates activate certain receptors in primary sensory neurons, which then act via neuronal circuits to reduce the repetitive firing, or hyperexcitability, of alpha-motor neurons in the spinal cord, thereby preventing or reducing the frequency and intensity of muscle cramps and spasms. The Company intends to initially focus drug development efforts on developing products to treat nocturnal leg cramps, spasms, spasticity and cramping associated with multiple sclerosis and motor neuron disease, such as amyotrophic lateral sclerosis. In the second quarter of 2016, the Company also expect to launch a consumer brand with a cornerstone product to prevent and treat exercise-associated muscle cramps.

The Company is subject to risks common to companies in the biotechnology and consumer products industries, including, but not limited to, risks of failure of pre-clinical studies, clinical studies and clinical trials, the need to obtain marketing approval for its drug product candidates, the need to successfully commercialize and gain market acceptance of its drug product candidates and its consumer products, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations and ability to transition from pilot-scale manufacturing to large-scale production of products.
In February 2015, the Company sold 5,491,191 shares of common stock (inclusive of 91,191 shares of common stock sold by the Company pursuant to the exercise of an overallotment option granted to the underwriters in connection with the offering) through an underwritten initial public offering ("IPO") at a price of $16.00 per share. The aggregate net proceeds received by the Company from the offering were approximately $79,900,000, after deducting underwriting discounts and commissions and offering expenses payable by the Company of approximately $8,000,000 (See Note 2).
Liquidity
The Company has incurred an accumulated deficit of $46,744,951 since inception and will require substantial additional capital to fund its research and development and the launch and growth of its consumer brand and cornerstone consumer product. The Company had unrestricted cash, cash equivalents and marketable securities of $84,376,806 at March 31, 2016. The Company believes its existing cash, cash equivalents and marketable securities will be sufficient to allow the Company to fund its current operating plan for at least the next 12 months.
2. Summary of significant accounting policies and recent accounting pronouncements
The accompanying unaudited condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the condensed consolidated financial statements. As of March 31, 2016, the Company’s significant accounting policies, which are detailed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (the “2015 10-K”), have not changed, other than as noted below.
Inventory
The Company expects to launch its cornerstone consumer product in the second quarter of 2016 and began capitalizing inventory costs associated with this product in the first quarter of 2016, when it was determined that the inventory costs had probable future economic benefit. Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out ("FIFO") basis.
The Company outsources the manufacture of its consumer product to a co-packer. Inventory at March 31, 2016 includes raw materials and work-in-process related to the initial production run of its consumer product that will be sold upon launch.

8

The Company periodically analyzes its inventory levels and writes down inventory that has become obsolete, has a cost basis in excess of its estimated realizable value, or exceeds projected sales. Estimates of excess inventory consider factors such as inventory levels, production requirements, projected sales and the estimated shelf-lives of inventory components. Inventory write-offs are recorded as a component of cost of production (or cost of product revenue upon revenue generation).
Unaudited interim financial information

Certain information and footnote disclosures normally included in the Company’s annual financial statements have been condensed or omitted. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the 2015 10-K.

The condensed consolidated financial statements as of March 31, 2016, for the three months ended March 31, 2016 and 2015, and the related information contained within the notes to the condensed consolidated financial statements, are unaudited. The unaudited condensed consolidated financial statements have been prepared on the same basis as annual audited consolidated financial statements, and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s condensed consolidated financial position as of March 31, 2016, and the statements of operations, comprehensive loss and cash flows for the three months ended March 31, 2016 and 2015. The results for the three months ended March 31, 2016 are not necessarily indicative of results to be expected for the year ending December 31, 2016, or any other future annual or interim periods.
Initial public offering
On February 3, 2015, the Company completed its IPO, whereby the Company sold 5,491,191 shares of its common stock (inclusive of 91,191 shares of common stock sold by the Company pursuant to the exercise of an overallotment option granted to the underwriters in connection with the IPO) at a price of $16.00 per share. The shares began trading on the Nasdaq Global Market on January 29, 2015. The aggregate net proceeds received by the Company from the IPO were approximately $79,900,000, after deducting underwriting discounts and commissions and other offering expenses payable by the Company. Upon the closing of the IPO, all outstanding shares of convertible preferred stock converted into 6,971,108 shares of common stock. Additionally, the Company is now authorized to issue 100,000,000 shares of common stock.
Deferred IPO issuance costs, which primarily consisted of direct incremental legal and accounting fees related to the Company's IPO, were previously capitalized at December 31, 2014. Upon the closing of the IPO in February 2015, IPO issuance costs, which totaled $1,848,737, were offset against the IPO proceeds within additional paid-in capital.
Basis of presentation and use of estimates
The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, the Company's management evaluates its estimates, which include, but are not limited to, estimates related to clinical study accruals, estimates related to inventory realizability, stock-based compensation expense, and amounts of expenses during the reported period. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Actual results may differ from those estimates or assumptions.
Principles of consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries: TK Pharma, Inc., a Massachusetts Securities Corporation, and Flex Innovation Group LLC, which contains the

9

Company's consumer-related operations. All significant intercompany balances and transactions have been eliminated in consolidation.

Concentration of Risk
The Company outsources the manufacture of its cornerstone consumer product to a co-packer that produces bottled finished goods. The Company also sources certain raw materials from sole suppliers. A disruption in the supply of materials or the production of finished goods could significantly impact the Company's revenues in the future as alternative sources of raw materials and co-packing may not be available at commercially reasonable rates or within a reasonably short period of time.
Recent accounting pronouncements

In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330). This ASU simplifies the measurement of inventory by requiring certain inventory to be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016 and for interim periods therein. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The Company is currently in the process of evaluating the impact of the guidance related to the Company's consumer product launch.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU provides for a single comprehensive model for use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for interim and annual periods beginning after December 15, 2016 with no early adoption permitted. In July 2015, the FASB deferred the effective date of this accounting update to annual periods beginning after December 15, 2017, along with an option to permit early adoption as of the original effective date. The Company is required to adopt the amendments in the ASU using one of two acceptable methods: retrospectively to all prior reporting periods presented, with certain practical expedients permitted; or retrospectively with the cumulative effect of initially adopting the ASU recognized at the date of initial application. The Company is currently in the process of evaluating the impact of the guidance related to the Company's anticipated launch of its consumer product in the second quarter of 2016.

In August 2014, the FASB issued ASU No. 2014-15 Presentation of Financial Statements - Going Concern (Subtopic 205-40) . The ASU requires management of public and private companies to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, and substantial doubt is not alleviated after consideration of management’s plans, an entity should include a statement in the footnotes indicating that there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The new standard is effective for annual periods ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company has concluded, that if this standard had been adopted as of March 31, 2016, substantial doubt about the Company’s ability to continue as a going concern does not exist.

In February 2016, the FASB issued ASU No. 2016-02 Leases. The ASU requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by most leases and continue to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements and disclosures.

10

In March 2016, the FASB issued ASU No. 2016-09 Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The ASU simplifies several aspects of the accounting for employee share-based payment transactions. The amendments in the update include income tax consequences related to excess tax benefits and tax deficiencies, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all entities in any interim or annual period. The Company is currently evaluating the impact of ASU 2016-09 on its consolidated financial statements and disclosures.

The Company believes that the impact of other recently issued standards that are not yet effective will not have a material effect on its consolidated financial position or results of operations upon adoption.
3. Fair value measurements
The Company records cash equivalents and marketable securities at fair value. ASC Topic 820 Fair Value Measurements and Disclosures  established a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). The hierarchy consists of three levels:
Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, directly or indirectly, for substantially the full term of the asset or liability.
Level 3 – Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.
The following tables summarize the cash equivalents and marketable securities measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015:

Cash equivalents and marketable securities have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third-party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. The majority of the Company's cash equivalents consist of money market funds that are valued based on publicly available quoted market prices for identical

11

securities as of March 31, 2016. After completing its validation procedures, the Company did not adjust or override any fair value carrying amounts of as of March 31, 2016.
The Company evaluates transfers between levels at the end of each reporting period. There were no transfers of assets or liabilities between Level 1 and Level 2 during the three months ended March 31, 2016 or the year ended December 31, 2015. The Company had no financial assets or liabilities that were classified as Level 3 at any point during the three months ended March 31, 2016 or the year ended December 31, 2015.
4. Cash equivalents and marketable securities
The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash equivalents as of March 31, 2016 and December 31, 2015 consisted of money market funds.
Marketable securities as of March 31, 2016 consisted of corporate debt securities and U.S. government agency securities. Marketable securities as of December 31, 2015 consisted of corporate debt securities. Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. The Company classifies its marketable securities as available-for-sale pursuant to ASC 320,  Investments – Debt and Equity Securities . Marketable securities are recorded at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive income (loss) in stockholders’ equity and a component of total comprehensive income (loss) in the condensed consolidated statement of comprehensive income (loss), until realized. Realized gains and losses are included in investment income on a specific-identification basis. There were immaterial realized gains on marketable securities during the three months ended March 31, 2016. The Company did not have marketable securities during the three months ended March 31, 2015.
The Company reviews marketable securities for other-than-temporary impairment whenever the fair value of a marketable security is less than the amortized cost and evidence indicates that a marketable security’s carrying amount is not recoverable within a reasonable period of time. Other-than-temporary impairments of investments are recognized in the consolidated statement of operations if the Company has experienced a credit loss, has the intent to sell the marketable security, or if it is more likely than not that the Company will be required to sell the marketable security before recovery of the amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company’s investment policy, the severity and the duration of the impairment and changes in value subsequent to the end of the period.
Marketable securities at March 31, 2016 and December 31, 2015 consisted of the following:

 	Amortized Cost	 	Unrealized Gains	 	Unrealized Losses	 	Fair Value

At March 31, 2016, all investments held by the Company were classified as current. The Company had $24,652,348 of marketable securities classified as current and $2,312,949 of marketable securities classified as noncurrent as of December 31, 2015. Investments classified as current have maturities of less than one year. Investments classified as noncurrent are those that (i) have a maturity greater than one year and (ii) management

12

does not intend to liquidate within the next year, although these funds are available for use and therefore classified as available-for-sale.
The Company held two and eleven debt securities that were in an unrealized loss position at March 31, 2016 and December 31, 2015, respectively, all of which have been in a continuous loss position for less than 12 months. The aggregate fair value of debt securities in an unrealized loss position was $4,611,360 and $24,967,915 at March 31, 2016 and December 31, 2015, respectively. There were no individual securities that were in a significant unrealized loss position as of March 31, 2016 or December 31, 2015. The Company evaluated its securities for other-than-temporary impairment and considered the decline in market value for the securities to be primarily attributable to current economic and market conditions. The Company has the intent and ability to hold such securities until recovery. Based on this analysis, these marketable securities were not considered to be other-than-temporarily impaired as of March 31, 2016.
5. Inventory
The Company began capitalizing inventory as of March 31, 2016, as it was determined that the inventory had a probable future economic benefit. Inventory has been recorded at cost as of March 31, 2016. Costs capitalized at March 31, 2016 relate to the initial production run of the Company's cornerstone consumer product that will be sold upon launch. The Company held no inventory at December 31, 2015. Work in process is calculated based upon a buildup of cost for each stage of production.
The following table presents inventory:

7. Common stock
As of March 31, 2016, the Company had authorized 100,000,000 shares of common stock, $0.0001 par value per share. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the board of directors. The Company does not intend to declare dividends for the foreseeable future.

13

Restricted common stock to founders
In March 2014, the Company sold 4,553,415 shares of restricted common stock to the founders of the Company ("recipients"), for $0.0004 per share, for total proceeds of $1,950. In April 2014, based upon anti-dilution provisions granted to the recipients, an additional 867,314 shares of restricted common stock were sold to the same recipients, after which the anti-dilution provisions were terminated. The restricted common stock vested 25% upon issuance, and the remaining 75% vests ratably over four years, during which time the Company has the right to repurchase the unvested shares held by a recipient if the relationship between such recipient and the Company ceases. If the relationship terminates, the Company has 90 days to repurchase unvested shares at $0.0004 per share. Such shares are not accounted for as outstanding until they vest. There were 3,472,543 shares of restricted common stock outstanding as of March 31, 2016. Unvested restricted common stock awards to non-employees are re-measured at each vest date and each financial reporting date.
The following is a summary of restricted common stock activity:

Restricted common stock to consultants
During the three months ended March 31, 2016,the Company issued 18,194 shares of restricted common stock to non-employee consultants and advisors. The Company has the right to repurchase any unvested shares held by a recipient if the relationship between such recipient and the Company ceases. If the relationship terminates, the Company has 90 days to repurchase unvested shares at $0.0001 per share. Such shares are not accounted for as outstanding until they vest. There were 3,235 shares of restricted common stock outstanding as of March 31, 2016. Unvested restricted common stock awards to non-employees are re-measured at each vest date and each financial reporting date.

8. Stock-based compensation
In March 2014, the Company adopted the Flex Pharma, Inc. 2014 Equity Incentive Plan (the "2014 Plan"), under which it had the ability to grant incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units and stock appreciation rights to purchase up to 116,754 shares of common stock. In April

14

2014, the Company amended the 2014 Plan to reserve for the issuance of up to 1,451,087 shares of common stock pursuant to equity awards. In September 2014, the Company further amended the 2014 Plan to reserve for the issuance of up to 2,070,200 shares of common stock pursuant to equity awards. Terms of stock award agreements, including vesting requirements, were determined by the board of directors, subject to the provisions of the 2014 Plan. For options granted under the 2014 Plan, the exercise price equaled the fair market value of the common stock as determined by the board of directors on the date of grant. No further awards will be granted under the 2014 Plan.
In January 2015, the Company's board of directors adopted, and the Company's stockholders approved, the 2015 Equity Incentive Plan (the "2015 Plan"), which became effective immediately prior to the closing of the Company's IPO. The 2015 Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance-based stock awards, and other stock-based awards. Additionally, the 2015 Plan provides for the grant of performance-based cash awards. ISOs may be granted only to the Company's employees. All other awards may be granted to the Company's employees, including officers, and to non-employee directors and consultants. As of March 31, 2016, there were 388,604 shares remaining available for the grant of stock awards under the 2015 Plan.
The Company has awarded stock options to its employees, directors, advisors and consultants, pursuant to the plans described above. Stock options subsequent to the completion of the Company's IPO are granted with an exercise price equal to the closing market price of the Company's common stock on the date of grant. Stock options generally vest over one to four years and have a contractual term of ten years. Stock options are valued using the Black-Scholes option pricing model and compensation cost is recognized based on the resulting value over the service period. Unvested awards to non-employees are re-measured at each vest date and at each financial reporting date. The following table summarizes stock option activity for employees and non-employees for the three months ended March 31, 2016:

15

 	

As of March 31, 2016, there was approximately $15,752,157 of total unrecognized compensation cost related to unvested equity awards. Total unrecognized compensation cost will be adjusted for the re-measurement of non-employee awards as well as future changes in employee and non-employee forfeitures, if any. The Company expects to recognize that cost over a remaining weighted-average period of 2.46 years.
In November 2015, the Company granted 150,000 performance-based stock options to an employee which are included in the table of stock option activity above. The options will vest based upon the achievement of certain future revenue milestones. As of March 31, 2016, the achievement of these vesting milestones was not considered probable. Unrecognized stock-based compensation expense related to this award was approximately $1,000,000 as of March 31, 2016. The Company records stock-based compensation expense for stock option grants subject to performance-based vesting over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates when the achievement of a performance-based milestone is probable based on the relative satisfaction of the performance conditions as of the reporting date.
Employee stock purchase plan
In January 2015, the Company's board of directors adopted, and the Company's stockholders approved, the 2015 Employee Stock Purchase Plan (the "ESPP"), which became effective upon the date of execution of the underwriting agreement pursuant to which the Company's common stock was priced in connection with the IPO. As of March 31, 2016, the Company had not yet instituted any offering periods under the ESPP and no shares of the Company's common stock have been purchased under the ESPP.
9. Income taxes
Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Based upon the Company's history of operating losses and the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against the Company’s otherwise recognizable net deferred tax assets. There was no significant income tax provision or benefit for the three months ended March 31, 2016 or March 31, 2015.

10. Net loss per share
Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and dilutive common stock equivalents outstanding for the period, determined using the treasury stock method and the if-converted method, for convertible securities, if inclusion of these is dilutive.
Because the Company has reported a net loss for the periods presented, diluted net loss per common share is the same as basic net loss per common share.
The following potentially dilutive securities outstanding, prior to the use of the treasury stock method or if-converted method, have been excluded from the computation of diluted weighted-average shares outstanding for the periods indicated, because including them would have had an anti-dilutive impact:

Item 2.	Management’s Discussion and Analysis of Financial Condition and Results of Operations	
The following discussion and analysis should be read in conjunction with the unaudited financial information and the notes thereto included herein, as well as our audited consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2015. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under "Risk Factors" discussed in our Annual Report on Form 10-K for the year ended December 31, 2015.
Introduction
Our Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is provided in addition to the accompanying condensed consolidated financial statements and notes to assist readers in understanding our results of operations, financial condition, and cash flows. MD&A is organized as follows:
Overview - A discussion of our business and overall analysis of financial and other highlights affecting the company in order to provide context for the remainder of MD&A.
Results of Operations - An analysis of our financial results comparing the three months ended March 31, 2016 to the three months ended March 31, 2015.
Liquidity and Capital Resources - An analysis of changes in our condensed consolidated balance sheets and cash flows, and discussion of our financial condition and potential sources of liquidity.
Critical Accounting Policies and Significant Judgments and Estimates - A discussion of critical accounting policies that require us to make subjective estimates and judgments.
Overview
We are a biotechnology company that is developing innovative and proprietary treatments for nocturnal leg cramps, muscle cramps and spasms associated with severe neuromuscular conditions, and exercise-associated muscle cramps. Our product candidates are based on the potential mechanism of action we describe as Chemical Neuro Stimulation, which is the process by which a small molecule chemical signal, acting topically, induces a neuronal sensory signal that produces a beneficial effect. Our product candidates activate certain receptors in primary sensory neurons, which then act via neuronal circuits to reduce the repetitive firing, or hyperexcitability, of alpha-motor neurons in the spinal cord, thereby preventing or reducing the frequency and intensity of muscle cramps and spasms. We intend to initially focus our drug development efforts on developing products to treat nocturnal leg cramps, spasms, spasticity and cramping associated with multiple sclerosis and motor neuron disease, such as amyotrophic lateral sclerosis.

In the second quarter of 2016, we expect to launch a consumer brand with a cornerstone product to prevent and treat exercise-associated muscle cramps, or EAMCs. Using our extract formulation, we developed a consumer product that will be marketed primarily to endurance athletes experiencing EAMCs. Our cornerstone consumer product will be a 50 milliliter beverage containing a proprietary formulation of organic transient receptor potential, or TRP, ion channel activators. We expect to launch our consumer brand with our cornerstone product in the three select markets of Los Angeles, California, Boulder, Colorado and Boston, Massachusetts, and also expect a significant online presence. We have conducted pre-launch activities in each of these locations, which have

included, among other things, attending athletic events, providing product samples, gathering feedback, educating potential consumers of our product and launching a print and digital media campaign.
We have incurred an operating loss since our inception and we anticipate that we will continue to incur operating losses for at least the next several years. Our net loss was $9.6 million for the three months ended March 31, 2016 and $6.0 million for the three months ended March 31, 2015. Our accumulated deficit was $46.7 million as of March 31, 2016. To date, we have financed our operations with net proceeds from the private placement of our preferred stock and our initial public offering. We expect that our research and development and selling, general and administrative expenses will continue to increase from their current levels as we continue the development of our drug product candidates, and we will incur significant selling and marketing expense associated with the launch of our consumer brand, the launch of our cornerstone product in the second quarter of 2016 and any future consumer products. As a result, we will need additional capital to fund our future operations.
Recent Developments
On February 2, 2016, we announced that our extract formulation demonstrated efficacy in treating subjects with nocturnal leg cramps in a randomized, controlled, blinded study. In April 2016, we presented results from this study at the American Academy of Neurology (AAN) 68 th  Annual Meeting, where it had been selected for a late-breaking presentation. The extract formulation resulted in a median reduction of six total cramps over a two-week period compared with four cramps while the subjects were on vehicle control (p<0.05). During the treatment period, subjects saw a median increase of two total cramp-free nights compared with only one cramp free night while the subjects were on vehicle control (p<0.01). Statistically significant effects were also demonstrated on the following key endpoints: the physician-rated Clinical Global Impression of Change (CGI-C) (p<0.01); specific sleep disturbance measures (p<0.05); and specific pain measures (p<0.01). Additionally, the extract formulation appeared to be safe and well-tolerated and there were no serious adverse events reported. The positive effects were seen across a broad range of enrolled subjects; in addition, a subset of patients showed pronounced benefit.

Later this year, we expect to initiate another study in subjects with nocturnal leg cramps with a single molecule, TRP activator, with results expected in the first half of 2017. We expect this study will be a randomized, controlled, blinded, cross-over design and will be slightly larger than the previous study of our extract formulation. The study article will likely be formulated as an orally disintegrating tablet, or ODT. In addition, as part of our nocturnal leg cramps development program, we are also concurrently conducting smaller studies, exploring potentially alternative study designs, delivery mechanisms, dosage amounts and product formulations. We believe these studies will help inform the formal clinical trials that we expect to begin next year following the filing of an investigational new drug application, or IND, with the U.S. Food and Drug Administration.
In March 2016, we announced that Michelle Stacy, former President of Keurig Inc., had joined our Board of Directors.
In April 2016, we announced that results from a study showing our extract formulation prevented volitional muscle cramps were presented at the Experimental Biology conference. In the study, run by academics at The Pennsylvania State University, our extract formulation showed a statistically significant benefit in reducing muscle cramps in athletes as compared to vehicle control (as measured by the intensity-duration profile of voluntarily induced muscle cramps). Additionally, subject ratings of muscle soreness resulting from cramps were also lower compared to vehicle control. The research at the Noll Laboratory at Pennsylvania State University supports the development of our consumer product and complements our electrically-induced cramp model.
Components of Operating Results
Revenue
To date, we have not generated any revenue. In the future, we may generate revenue from a combination of consumer product sales, drug product sales, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements, or a combination of these sources. To the extent any of our products are successfully commercialized, we expect that any revenue we generate will fluctuate from quarter to quarter as a result of the amount and timing of payments that we receive from the sale of our products, the timing and amount of license fees, milestone and other payments. If we fail to complete the development of our drug product candidates in a timely manner or obtain regulatory approval for them or fail to successfully commercialize our consumer products, our ability to generate future revenue, and our results of operations and financial position, would be materially adversely affected.
Cost of Production

18

Table of Contents

We outsource the manufacture of our cornerstone consumer product to a co-packer. We began the initial production run of our cornerstone consumer product in the first quarter of 2016, in advance of our planned launch in the second quarter of 2016. The cost of production for the first quarter of 2016 includes an inventory write-off related to materials purchased for finished goods that, upon completion of production, are not expected to be sold based upon projected sales, a 12 month product shelf life and production requirements. Cost of production also includes depreciation expense related to manufacturing equipment purchased to support production.

Upon the launch of our cornerstone consumer product, cost of production (or cost of product revenue upon revenue generation) will include the cost of raw materials utilized in the manufacture of our consumer product, co-packing fees, repacking fees, in-bound freight charges, as well as other expenses incurred during the manufacture of the Company's finished goods. Also included in this cost will be any future write-offs of inventory that has become obsolete, that has a cost basis in excess of its estimated realizable value, or exceeds projected sales. The amount of any future inventory write-off will vary based upon factors such as inventory levels, production levels, projected sales of our consumer product and shelf-lives of our inventory components. If we are not successful in generating sufficient levels of revenue from our consumer product or if our other estimates prove to be inaccurate, additional inventory write-downs may be required.
Research and Development Expenses
Our research and development expenses to date have related primarily to the development and testing of our extract formulation for muscle cramps in the United States. We also incurred research and development expenses related to the testing and development of a single molecule, chemically synthesized, TRP ion channel activator, including FLX-787, our clinical candidate outside the United States. Research and development costs include salaries and other compensation-related costs, such as stock-based compensation, for research and development employees, costs of clinical studies of our extract formulation and drug product candidates including costs of clinical studies outside of the United States, costs for consultants who we utilize to supplement our personnel, fees paid to third-parties, facilities and overhead expenses, cost of laboratory supplies and other outside expenses.

Research and development activities are central to our business model. Drug product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase in the future as we increase personnel and compensation costs, increase our research efforts, conduct clinical studies and trials in multiple indications, and perform preclinical work on our drug product candidates. It is difficult to determine, with certainty, the duration and completion costs of our current or future preclinical programs, clinical studies and clinical trials of our product candidates.

In addition, the probability of success for each drug product candidate will depend on numerous factors, including competition, product safety and efficacy, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of our drug product candidates, as well as an assessment of each product candidate's commercial potential.

Research and development expenses also include costs incurred related to our cornerstone consumer product, including athlete-based efficacy studies, product formulation work, stability studies and other efforts.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of salaries and other compensation-related costs, including stock-based compensation, for personnel in executive, finance and accounting, legal, corporate communications and general administration roles. Other significant costs include professional service fees including legal fees relating to patent and corporate matters, accounting fees, insurance costs, costs for consultants who we utilize to supplement our personnel, travel costs, and facility and office-related costs not otherwise included in research and development expenses.
Selling, general and administrative expenses also include costs related to our consumer brand and our cornerstone product. To date, these costs have included personnel costs, brand development costs, market research costs, product design costs, pre-launch activity costs and other external costs. We are preparing to launch our cornerstone consumer product in the second quarter of 2016 and expect to initially target the following select geographic markets: Los Angeles, California, Boulder, Colorado and Boston, Massachusetts. We have continued pre-launch activities through March 31, 2016, which have included, among other things, attending athletic events, providing product samples, gathering feedback, educating potential consumers of our product, and launching a print a

nd digital media campaign. As we prepare to launch our cornerstone consumer product in the second quarter of 2016, costs will increase as we hire additional personnel to support our pre-launch and launch activities and incur costs related to branding, packaging, distribution, print and digital media and other related sales and promotion activities. In the future, we may also pursue relationships with endurance athletes, figures or teams prominent in the athletic community.

We anticipate that our selling, general and administrative expenses will increase in the future to support the commercialization of our cornerstone consumer product, the potential commercialization of future consumer products and drug product candidates and the increased general and administrative needs of the organization.
Interest Income, Net
Interest income, net primarily consists of interest income from our cash, cash equivalents and marketable securities, amortization and accretion of investment premiums and realized gains and losses.

Cost of Production
Cost of production was $0.2 million for the three months ended March 31, 2016 and primarily related to an inventory write-off of material purchased for finished goods that, upon completion of production, are not expected to be sold based upon projected sales, a 12 month product shelf life and production requirements. There was no cost of production for the three months ended March 31, 2015.

Research and Development Expenses
Research and development expenses were $4.4 million for the three months ended March 31, 2016 compared to $2.8 million for the three months ended March 31, 2015. The increase of $1.6 million was primarily related to:
 	 	
•	$1.3 million of increased costs related to IND-supporting pre-clinical activities for our drug product candidate, clinical studies of our extract formulation and clinical studies of alternate formulations of our extract formulation;	
 	 	
•	$0.4 million of costs for clinical studies of our clinical candidate outside the United States, FLX-787;	
 	 	
•	$0.3 million increase in salaries expense related to increased headcount; and	

20

Table of Contents
 	 	
•	$0.4 million decrease in stock-based compensation expense, primarily due to the impact of the lower current year stock price on the revaluation of non-employee stock awards, partially offset by current quarter stock option awards.	
Selling, General and Administrative Expenses
Selling, general and administrative expenses were $5.1 million for the three months ended March 31, 2016 compared to $3.2 million for the three months ended March 31, 2015. The increase of $1.9 million was primarily related to:
 	 	
•	$0.9 million of increased personnel costs including salaries and other compensation-related costs, including stock-based compensation, as we added personnel to support the launch of our consumer brand with a cornerstone product, as well as additional administrative personnel hired to support our growth and increased activities;	
 	 	
•	$0.8 million of increased external costs related to developing our consumer brand and cornerstone consumer product, including brand development and strategy costs, marketing and promotional costs and pre-launch activities. These costs increased in the current quarter in advance of the consumer launch in the second quarter of 2016;	
 	 	
•	$0.1 million of increased external consulting costs incurred to supplement our general and administrative personnel due to increased personnel and activity; and	
 	 	
•	$0.1 million increase in other costs, including professional service fees such as legal costs, due to increased activity versus the prior year.	
Liquidity and Capital Resources
Overview
Since inception, we have incurred an operating loss and we anticipate that we will continue to incur operating losses for at least the next several years. To date, we have not generated any revenues. We expect that our research and development and selling, general and administrative expenses will continue to increase, and we will incur significant sales and marketing expense associated with the launch and commercialization of our consumer brand with our cornerstone consumer product. As a result, we will need additional capital to fund our operations, which we may raise through a combination of equity offerings, debt financings, other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements.
Since our inception, we have financed our operations through private placements of equity securities and our IPO, which we completed in February 2015. As of March 31, 2016, we had $84.4 million in cash, cash equivalents and marketable securities, which were held in bank deposit accounts, money market funds, corporate debt and U.S. government agency securities.

Table of Contents

The increase in cash used in operations for the three months ended March 31, 2016 compared to the three months ended March 31, 2015 was primarily due to our significant increase in operations. For the three months ended March 31, 2016, we incurred increased costs related to our personnel, increased costs related to our research and development efforts including clinical study costs, increased costs associated with our consumer product development and launch efforts and increased costs needed to support our operations.
Investing Activities
Net cash used in investing activities for the three months ended March 31, 2016 related to $3.4 million of net purchases and sales of marketable securities. We did not hold any marketable securities during the three months ended March 31, 2015. Property and equipment acquisitions increased $0.1 million primarily related to manufacturing equipment used to produce our consumer product.
Financing Activities
Net cash provided by financing activities was $7,594 during the three months ended March 31, 2016 compared to $80.8 million for the three months ended March 31, 2015. During the three months ended March 31, 2015, we completed our IPO, which resulted in net proceeds of $79.9 million.
As of March 31, 2016, we had no long-term debt.
We currently have no ongoing material financial commitments, such as lines of credit or guarantees that are expected to affect our liquidity over the next five years, other than leases.
Funding Requirements
We expect that we will require additional funding to support the launch and growth of our consumer brand and products and to develop and commercialize our drug product candidates. In addition, if we receive regulatory approval for any of our drug product candidates, and if we choose not to grant rights to commercialize our drug products to partners, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution activities. We also expect to incur additional costs to support our operations as well as the costs associated with operating as a public company.
Until we can generate a sufficient amount of revenue from our products, if ever, we expect to finance future cash needs through public or private equity or debt offerings. Additional capital may not be available on reasonable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of one or more of our product candidates. If we raise additional funds through the issuance of additional debt or equity securities, it could result in dilution to our existing stockholders, increased fixed payment obligations and these securities may have rights senior to those of our common stock. If we incur indebtedness, we could become subject to covenants that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any of these events could significantly harm our business, financial condition and prospects.
Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, clinical costs, third-party research and development costs, legal and other regulatory expenses, manufacturing, marketing, promotion and selling costs related to our consumer brand and products, external consulting costs and general administrative and overhead costs. Our future funding requirements will be heavily reliant upon the resources required to support our drug product candidates as well as our consumer brand and products.
Pre-Clinical Drug Product Candidates
The successful development of any drug product candidate is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the development of our future drug product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from the sale of drug product candidates. This is due to the numerous risks and uncertainties associated with developing drug products, including the uncertainty of:
 	 	
•	successfully enrolling, and completing, clinical studies and trials;	
 	 	
•	receiving marketing approvals from applicable regulatory authorities;	
 	 	
•	establishing arrangements with third-party manufacturers;	

22

Table of Contents
 	 	
•	obtaining and maintaining patent and trade secret protection and regulatory exclusivity; and	
 	 	
•	launching commercial sales of our products, if and when approved, whether alone or in collaboration with others.	
A change in the outcome of any of these variables with respect to the development of any of our drug product candidates would significantly change the costs and timing associated with the development of that drug product candidate.
As all of our drug product candidates are in the early stage of development and the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our drug product candidates.
Consumer Brand and Products
The development and launch of our consumer brand, our cornerstone product and future products is uncertain, including the timing and resources needed to support successful commercialization. Our future success depends, in large part, on our ability to implement a launch and growth strategy that establishes distribution and placement of our products, attracts consumers to our cornerstone product and future product offerings and maintains brand loyalty for our consumer products.
Our future funding requirements will be impacted by our ability to successfully launch and grow our consumer brand and products. Delays or unexpected costs related to the consumer brand and cornerstone product launch and growth plans could significantly change the costs and the timing of such costs associated with our consumer products
Outlook
Based on our research and development plans, our consumer brand and cornerstone product launch plans and our expectations of timing related to the progress of our clinical programs, we expect that our existing cash resources and marketable securities will enable us to fund our costs and expenses and capital expenditure requirements through mid-2018. We have based this estimate on assumptions that may prove to be wrong, however, and we could use our capital resources sooner than we expect. Additionally, the process of testing drug product candidates in clinical trials is costly, as are the resources required to launch a consumer brand and products, and the timing of progress of these efforts is uncertain.
Contractual Obligations
There have been no material changes to our contractual obligations from those described in our Annual Report on Form 10-K for the year ended December 31, 2015.
Off-Balance Sheet Arrangements
We did not have during the period presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules.
Critical Accounting Policies and Significant Judgments and Estimates
Our management's discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the condensed consolidated balance sheet and the reported amounts of expenses during the reporting period. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances at the time such estimates are made. Actual results may differ materially from our estimates and judgments under different assumptions or conditions. We periodically review our estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in our consolidated financial statements prospectively from the date of the change in estimate.
There have been no material changes to our critical accounting policies from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K for the year ended December 31, 2015, other than as noted below.

Inventory
Inventory consists of costs related to the manufacture of our cornerstone consumer product, which is produced for us by a co-packer.
Beginning in the first quarter of 2016, we began to capitalize inventory costs associated with our cornerstone consumer product when it was determined that the inventory had a probable future economic benefit. Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, basis. We periodically analyze our inventory levels, and write down inventory that has become obsolete, that has a cost basis in excess of its estimated realizable value or exceeds projected sales.
We may need to record additional inventory write-downs in the future which will vary based upon factors such as inventory levels, production levels, projected sales of our consumer product and shelf-lives of our inventory components. Our cornerstone consumer product is expected to have a 12 month shelf life upon launch. If we are not successful in generating sufficient levels of sales from our consumer product or if our other estimates prove to be inaccurate, additional inventory write-downs may be required.
During the first quarter of 2016, we recorded an inventory write-down of excess inventory totaling $0.2 million, based upon our analysis of projected sales, a 12 month product shelf life and production requirements.

Item 3.	Quantitative and Qualitative Disclosures about Market Risk	

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates. As of March 31, 2016, we had cash, cash equivalents and marketable securities of $84.4 million. We invest our cash in a variety of financial instruments, principally money market funds, U.S. government securities, investment-grade corporate notes and commercial paper. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. Available for sale securities that we invest in are subject to interest rate risk and may fall in value if market interest rates increase. Due to the short-term duration of our investment portfolio and the low risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our portfolio.

Item 4.	Controls and Procedures	

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure.

As of March 31, 2016, we have evaluated, under the supervision and with the participation of our management, including the chief executive officer and the principal financial and accounting officer, the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based upon our evaluation, the chief executive officer and the principal financial and accounting officer concluded that our disclosure controls and procedures were effective. Accordingly, management believes that the condensed consolidated financial statements included in this report fairly present in all material respects our consolidated financial condition, results of operations and cash flow for the periods presented

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2016, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

You should carefully review and consider the information regarding certain factors that could materially affect our business, financial condition or future results set forth under Item 1A. (Risk Factors) in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

There have been no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, except as follows:

Risks Related to Our Business Operations and Industry

We depend on third party manufacturers and suppliers, including sole source manufacturers and suppliers, for our consumer product. We may not be able to maintain these relationships and could experience supply disruptions outside of our control.

We rely on a network of third-party manufacturers to supply materials and manufacture our cornerstone consumer product. Our supply chain for sourcing raw materials and manufacturing is a multi-step endeavor. Third-party contract suppliers provide us with raw materials, and our co-packer converts these raw materials into finished goods available for sale. Establishing and managing this supply chain requires a significant financial commitment and the creation and maintenance of numerous third-party contractual relationships. Although we attempt to effectively manage the business relationships with companies in our supply chain, we do not have control over their operations. As a result of our reliance on these third-party manufacturers and suppliers, including a sole source co-packer and sole source suppliers of certain components of our consumer product, we could be subject to significant supply disruptions.

We currently rely, and expect to continue to rely, on a sole source third-party co-packer to manufacture, bottle and package our consumer product and have entered into a production agreement with this co-packer. We rely on other third-parties as the sole source of the raw materials for our consumer product and we have not yet entered into long term arrangements with these suppliers. There can be no assurance any of our sole source third-party manufacturers and suppliers will meet our commercial demands in a timely manner or that we will be to identify and establish relationships with qualified additional or back-up suppliers and manufacturers. Any supply or manufacturing disruptions could disrupt the sales of our consumer product, which could have a material, adverse impact on our business.

Item 2.	Unregistered Sales of Equity Securities and Use of Proceeds	
Recent sales of unregistered securities.
None.
Use of Proceeds
In February 2015, we completed our initial public offering pursuant to a registration statement on Form S-1 (File No. 333-201276), which the SEC declared effective on January 28, 2015. In our initial public offering, we issued and sold 5,491,191 shares of common stock (inclusive of 91,191 shares of common stock sold by us pursuant to the exercise of an overallotment option granted to the underwriters in connection with the offering) at a public offering price of $16.00 per share, for aggregate gross offering proceeds of $87.9 million. The managing underwriters for our initial public offering were Jefferies LLC, Piper Jaffray & Co., JPM Securities LLC, Cantor Fitzgerald & Co., and Roth Capital Partners, LLC.

Table of Contents

The aggregate net proceeds received by us from our initial public offering were $79.9 million, after deducting underwriting discounts and commissions and offering expenses payable by us. No offering expenses were paid directly or indirectly to any of our directors or officers (or their associates) or persons owning 10% or more of any class of our equity securities or to any other affiliates or to any other persons.

There has been no material change in the use of proceeds from our initial public offering as described in our final prospectus dated January 28, 2015 and filed with the SEC pursuant to Rule 424(b)(4) on January 29, 2015.
