SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We may, in some cases, use terms such as “predicts,” “believes,” “potential,” “proposed,” “continue,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “may,” “would,” “could,” “might,” “will,” “should,” “exploring,” “pursuing” or other words that convey uncertainty of future events or outcomes to identify these forward-looking statements.

Forward-looking statements appear in a number of places throughout this report and include statements regarding our intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things:

• the success, timing and cost of our ongoing and anticipated preclinical studies and clinical trials for our current product candidates and potential future product candidates, including statements regarding the timing of initiation and completion of the studies and trials;

• our expectations regarding the clinical effectiveness of our product candidates and results of our clinical trials;

• the timing of and our ability to obtain and maintain U.S. Food and Drug Administration (“FDA”) or other regulatory authority approval of, or other action with respect to, our product candidates;

• our expectations related to the use of proceeds from our initial public offering (“IPO”) in October 2013, the issuance and sale of our 2014 Convertible Notes (as defined herein) in September 2014 and the issuance and sale of common stock under our shelf registration statement on Form S-3 and “at-the-market” sales agreement;

• our estimates regarding anticipated capital requirements and our needs for additional financing;

• the commercial launch and potential future sales of our current or any other future product candidates;

• our commercialization, marketing and manufacturing capabilities and strategy;

• third-party payor reimbursement for our product candidates;

• the glaucoma patient market size and the rate and degree of market adoption of our product candidates by eye-care professionals and patients;

• the timing, cost or other aspects of the commercial launch of our product candidates;

• our plans to pursue development of our product candidates for additional indications and other therapeutic opportunities;

• the potential advantages of our product candidates;

• our plans to explore possible uses of our existing proprietary compounds beyond glaucoma;

• our ability to protect our proprietary technology and enforce our intellectual property rights;

• our expectations regarding collaborations, licensing, acquisitions and strategic operations, including our ability to in-license or acquire additional opthalmic products or product candidates; and

• our stated objective of building a major opthalmic pharmaceutical company.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics and industry change, and depend on regulatory approvals and economic and other environmental circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. We discuss many of these risks under the heading “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as filed with the Securities and Exchange Commission (“SEC”) on February 27, 2015, and in Part II, Item 1A of our Quarterly Report on Form 10-Q for the period ended March 31, 2015, as filed with the SEC on May 7, 2015. You should not rely upon forward-looking statements as predictions of future events.

Although we believe that we have a reasonable basis for each forward-looking statement contained in this report, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the evolution of the industry in which we operate may differ materially from the forward-looking statements contained in this report. In addition, even if our results of operations, financial condition and liquidity, and events in the industry in which we operate are consistent with the forward-looking statements contained in this report, they may not be predictive of results or developments in future periods.

ii

Any forward-looking statements that we make in this report are as of the date of this report. Except as required by law, we are under no duty to update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this report.

AERIE PHARMACEUTICALS, INC.

Notes to the Consolidated Financial Statements

(Unaudited)

1. The Company

Aerie Pharmaceuticals, Inc. (“Aerie”), with its wholly-owned subsidiaries Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Limited” and “Aerie Ireland Limited”, respectively, together with Aerie, the “Company”), is a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of topical, small molecule products to treat patients with glaucoma and other diseases of the eye. The Company has its principal executive offices in Irvine, California and operates as one business segment.

The Company has not yet commenced commercial operations and therefore has not generated product revenue. The Company’s activities since inception primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company does not expect to generate revenue until and unless it receives regulatory approval of and successfully commercializes its product candidates. The Company has incurred losses and experienced negative operating cash flows since inception.

The Company has funded its operations primarily through the sale of equity securities and issuance of convertible notes. In October 2013, the Company completed its initial public offering (“IPO”) and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. On September 30, 2014, the Company issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”). The Company received net proceeds from the issuance of the 2014 Convertible Notes of approximately $124.1 million, after deducting discounts and certain expenses of $875,000. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

On November 3, 2014, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale of up to a maximum aggregate offering price of $150.0 million of the Company’s common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock that may be issued and sold under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by the Company under the “at-the-market” sales agreement is included in the $150.0 million of common stock that may be offered, issued and sold by the Company under the shelf registration statement. As of and for the six months ended June 30, 2015, the Company issued and sold 1,224,548 shares of its common stock under the “at-the-market” sales agreement. The Company received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million.

In March 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands. In addition, Aerie assigned the beneficial rights to its non-U.S. and Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, Aerie and Aerie Limited entered into a research and development cost sharing agreement pursuant to which Aerie and Aerie Limited will share the costs of the development of intellectual property. Refer to Note 9 for a description of the tax impact of the IP Assignment. Additionally, in April 2015, the Company continued to prepare for foreign-based activities and established Aerie Ireland Limited as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited.

If the Company does not successfully commercialize any of its product candidates, it may be unable to generate product revenue or achieve profitability. Accordingly, the Company may be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or commercialization efforts. The Company currently estimates that it has sufficient funding to sustain operations through product commercialization of Rhopressa™ and Roclatan™, pending successful outcome of their clinical trials and U.S. Food and Drug Administration (“FDA”) approval.

2. Significant Accounting Policies

Basis of Presentation

The Company’s interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K. The results for the three and six months endedJune 30, 2015 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Principles of Consolidation

The interim consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of certificates of deposit, commercial paper, corporate bonds and government agency securities that are classified as available-for-sale in accordance with ASC 320, Investments—Debt and Equity Securities. The Company classifies investments available to fund current operations as current assets on its consolidated balance sheets. Investments are classified as long-term assets on the consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s consolidated balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three and six months endedJune 30, 2015 or 2014.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2015, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.

Deferred Financing Costs

Deferred financing costs consist of financing costs incurred by the Company in connection with the closing of Aerie’s 2014 Convertible Notes and are included in Other assets. The Company amortizes deferred financing costs through the earlier of maturity or the conversion of the 2014 Convertible Notes using the effective interest method. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

5

Fair Value Measurements

The Company records certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair value of the Company’s financial instruments, including cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses approximate their respective carrying values due to the short-term nature of these instruments. The carrying amounts of long-term investments represent their estimated fair values. The estimated fair value of Aerie’s 2014 Convertible Notes was $111.1 million and $163.8 million as of June 30, 2015 and December 31, 2014, respectively. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on June 30, 2015 as compared to December 31, 2014. As of June 30, 2015 and December 31, 2014, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets.

Software Capitalization

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software including external direct costs of materials and services involved with the software development. Capitalized software costs are included in Furniture, fixtures, and equipment and are amortized beginning when the software project is substantially complete and the asset is ready for its intended use. Costs incurred during the preliminary project stage and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (the “FASB”) issued ASU 2015-03, which simplifies the presentation of debt issuance costs. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2015, with early adoption permitted. Upon adoption of ASU 2015-03, the Company will present debt issuance costs as a direct reduction to the debt liability rather than as an asset on its consolidated balance sheets.

In August 2014, the FASB issued ASU 2014-15, which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for the Company for the annual period ending after December 15, 2016 and for annual and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements.

Net Loss per Share Attributable to Common Stock

Basic net loss per share attributable to common stock (“Basic EPS”) is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration, and shares that are unequivocally issuable under the Company’s equity compensation plans and are therefore included in the calculation of the weighted-average number of shares of common stock as common stock equivalents. Diluted net loss per share attributable to common stock (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss attributable to common stockholders used in calculating Basic EPS is adjusted for certain items related to the dilutive securities.

For all periods presented, the Company’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have the effect of reducing the net loss per share of common stock. Therefore, the denominator used to calculate Basic EPS and Diluted EPS is the same in all periods presented.

6

The Company’s potential common stock equivalents that have been excluded from the computation of Diluted EPS for all periods presented consist of the following:

5. Fair Value Measurements

The Company records certain financial assets and liabilities at fair value in accordance with the provisions of ASC Topic 820 on fair value measurements. As defined in the guidance, fair value, defined as an exit price, represents the amount that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, the guidance defines a three-tier value hierarchy that prioritizes the inputs used in the valuation methodologies in measuring fair value.

• Level 1—Unadjusted quoted prices in active, accessible markets for identical assets or liabilities.

• Level 2—Other inputs that are directly or indirectly observable in the marketplace.

• Level 3—Unobservable inputs that are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following tables summarize the fair value of financial assets and liabilities that are measured at fair value and the classification by level of input within the fair value hierarchy:

As of June 30, 2015 and December 31, 2014, the estimated fair value of Aerie’s 2014 Convertible Notes was $111.1 million and $163.8 million, respectively. The estimated fair value of the 2014 Convertible Notes was determined using a scenario analysis and Monte Carlo simulation model to capture the various features of the 2014 Convertible Notes. The scenario analysis and Monte Carlo simulation require the use of Level 3 unobservable inputs and subjective assumptions, including but not limited to the probability of conversion, stock price volatility, the risk free interest rate and credit spread. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on June 30, 2015 as compared to December 31, 2014. The estimates presented are not necessarily indicative of amounts that could be realized in a current market exchange. The use of alternative market assumptions and estimation methodologies could have a material effect on these estimates of fair value.

8. Convertible Notes

On September 30, 2014, Aerie issued the 2014 Convertible Notes to Deerfield Partners, L.P., Deerfield International Master Fund, L.P., Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. and Deerfield Special Situations International Master Fund, L.P. (collectively, “Deerfield”). On January 1, 2015, Deerfield Special Situations International Master Fund, L.P. transferred all of its rights under the 2014 Convertible Notes to Deerfield Special Situations Fund, L.P.

The 2014 Convertible Notes bear interest at a rate of 1.75% per annum payable quarterly in arrears on the first business day of each January, April, July and October. The 2014 Convertible Notes mature on the seventh anniversary from the date of issuance, unless earlier converted.

The 2014 Convertible Notes constitute a senior secured obligation of Aerie, collateralized by a first priority security interest in substantially all of the assets of Aerie. The 2014 Convertible Notes provide that, upon the request of Aerie, Deerfield will release all of the liens on the collateral if both of the following occur: (i) beginning one month after FDA approval of either Rhopressa™ or Roclatan™, shares of Aerie’s common stock have traded at a price above $30 per share (subject to adjustment for any subdivision or combination of outstanding common stock) for 30 consecutive trading days, and (ii) Aerie is prepared to close a financing that will be secured by a lien on Aerie’s assets, subject only to the release of the lien on Aerie’s assets held by Deerfield.

10

In connection with the IP Assignment, Aerie granted Deerfield a security interest in an intercompany promissory note and pledged 65% of the voting stock of Aerie Limited. Upon the request of Aerie, Deerfield will release the lien on the intercompany promissory note under certain circumstances.

At closing, Aerie paid Deerfield a one-time transaction fee of $625,000. In addition, Aerie reimbursed Deerfield in the amount of $250,000 for certain expenses incurred by Deerfield in connection with the transaction. Aerie also incurred $1.3 million of legal and advisory fees in connection with the transaction.

The 2014 Convertible Notes are convertible at any time at the option of Deerfield, in whole or in part, into shares of common stock, including upon the repayment of the 2014 Convertible Notes at maturity (the “Conversion Option”). However, upon conversion, Deerfield (together with their affiliates) is limited to a 9.985% ownership cap in shares of common stock (the “9.985% Cap”). The 9.985% Cap would remain in place upon any assignment of the 2014 Convertible Notes by Deerfield.

The initial conversion price is $24.80 per share of common stock (equivalent to an initial conversion rate of 40.32 shares of common stock per $1,000 principal amount of 2014 Convertible Notes), representing a 30% premium over the closing price of the common stock on September 8, 2014. The conversion rate and the corresponding conversion price are subject to adjustment for stock dividends (other than a dividend for which Deerfield would be entitled to participate on an as-converted basis), stock splits, reverse stock splits and reclassifications. In addition, in connection with certain significant corporate transactions, Deerfield, at its option, may (i) require Aerie to prepay all or a portion of the principal amount of the 2014 Convertible Notes, plus accrued and unpaid interest, or (ii) convert all or a portion of the principal amount of the 2014 Convertible Notes into, depending upon the type of transaction, shares of common stock or the right to receive upon consummation of the transaction the consideration Deerfield would have received had Deerfield converted the 2014 Convertible Notes immediately prior to the consummation of the transaction. The 2014 Convertible Notes provide for an increase in the conversion rate if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction. The maximum increase to the initial conversion rate, in connection with a significant corporate transaction, is 12.07 shares of common stock per $1,000 principal amount of 2014 Conversion Notes, which decreases over time and is determined by reference to the price of the common stock prior to the consummation of the significant corporate transaction or the value of the significant corporate transaction.

The agreement governing the 2014 Convertible Notes contains various representations and warranties, and affirmative and negative covenants, customary for financings of this type, including restrictions on the incurrence of additional debt and liens on Aerie’s assets. As of June 30, 2015, Aerie was in compliance with the covenants. The agreement governing the 2014 Convertible Notes also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie; the suspension, cancellation or revocation of governmental authorizations that are reasonably expected to have a material adverse effect on Aerie’s business; the acceleration of a specified amount of indebtedness; and the failure to deliver shares of common stock upon conversion of the 2014 Convertible Notes. If any event of default were to occur, and continue beyond any applicable cure period, the holders of more than 50% of the aggregate principal amount of the then outstanding 2014 Convertible Notes would be permitted to declare the principal and accrued and unpaid interest to be immediately due and payable.

The Company recorded the 2014 Convertible Notes as long-term debt at face value less debt discounts relating to fees and certain expenses paid to Deerfield in connection with the transaction. The Conversion Option is a derivative that qualifies for an exemption from bifurcation and liability accounting as provided for in ASC Topic 815, Derivatives and Hedging – Contracts in Entity’s Own Equity (“ASC 815”). Since the Conversion Option is not bifurcated as a derivative pursuant to ASC 815, the Company further evaluated the Conversion Option to determine whether it is considered a beneficial conversion feature (“BCF”). The Company determined that the initial accounting conversion price was greater than the fair value of the common stock at the close of trading on the date of issuance, therefore no BCF existed at inception. However, if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction, the increase to the initial conversion rate may cause a contingent BCF to exist at the time of conversion. The contingent BCF, if any, will be recognized in earnings when the contingency is resolved and will be measured using the fair value of the common stock at the close of trading on the date of issuance and the accounting conversion price as adjusted for such an increase to the initial conversion rate.

As of June 30, 2015, the Company recognized unamortized debt discounts of $782,000. Debt discounts are amortized using the effective interest method through the earlier of maturity or the conversion of the 2014 Convertible Notes.

11

The table below summarizes the carrying value of the 2014 Convertible Notes as of June 30, 2015:

(in thousands)	JUNE 30, 2015
Gross proceeds	$	125,000
Initial value of issuance costs recorded as debt discount	(875		)
Amortization of debt discount	93
Carrying value	$	124,218

For the three and six months endedJune 30, 2015, interest expense related to the 2014 Convertible Notes was $545,000 and $1.1 million, respectively.

9. Income Taxes

The IP Assignment resulted in the recognition of a taxable gain for U.S. federal and state income tax purposes. As of June 30, 2015, the estimated income tax liability was $8.7 million after utilization of net operating loss carry-forwards, current year losses generated through June 30, 2015 and quarterly estimated payments made through June 30, 2015. Under ASC 810, Consolidation, the income tax expense of $9.0 million for the six months ended June 30, 2015 was recorded as a prepaid asset. The income tax liability and prepaid asset are expected to be substantially reduced by current year losses projected after June 30, 2015. In accordance with ASC 810, Consolidation, the remaining estimated prepaid asset will be amortized into income tax expense over the estimated remaining patent life of the intellectual property subject to the IP Assignment, through approximately 2030.

As a result of the IP Assignment, the Company reversed approximately $40.8 million of its valuation allowance on certain deferred tax assets, primarily federal and state net operating losses, as of June 30, 2015. Due to the Company’s history of operating losses and lack of available evidence supporting future taxable income, the Company believes that a valuation allowance on its remaining deferred tax assets as of June 30, 2015 remains appropriate.

In addition, the IP Assignment is subject to complex tax and transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with the Company’s determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and the Company’s position were not sustained, the Company could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates and reduced cash flows than otherwise would be expected.

10. Stock Purchase Warrants

As of June 30, 2015, the following equity classified warrants were outstanding:

NUMBER OF UNDERLYING SHARES	EXERCISE PRICE PER SHARE		WARRANT EXPIRATION DATE	TYPE OF EQUITY SECURITY
2,006	$	5.00	March 2016	Common Stock
75,000	$	5.00	February 2019	Common Stock
75,000	$	5.00	November 2019	Common Stock
7,500	$	5.00	August 2020	Common Stock
408,295	$	0.05	December 2019	Common Stock

The warrants outstanding as of June 30, 2015 are all currently exercisable with weighted-average remaining lives of 4.32 years.

11. Stock-based Compensation

Stock-based compensation expense for options granted and restricted stock awards (“RSAs”) is reflected in the consolidated statement of operations as follows:

	THREE MONTHS ENDED   JUNE 30,				SIX MONTHS ENDED   JUNE 30,
(in thousands)	2015		2014		2015		2014
Research and development	$	583	$	237	$	1,094	$	852
General and administrative	2,893		2,145		5,123		3,452
Total	$	3,476	$	2,382	$	6,217	$	4,304

The estimated fair value of options granted is determined on the date of grant using the Black-Scholes option pricing model. Options granted to non-employees are revalued at each financial reporting period until required service is performed. Compensation expense related to RSAs is based on the market value of the Company’s common stock on the date of grant and is expensed on a straight-line basis (net of estimated forfeitures) over the vesting period.

As of June 30, 2015, the Company had $31.4 million of unrecognized compensation expense related to options granted under its equity plans. This cost is expected to be recognized over a weighted average period of 2.8 years as of June 30, 2015. The weighted average remaining contractual life on all outstanding options as of June 30, 2015 was 8.3 years.

As of June 30, 2015, the Company had $2.4 million of unrecognized compensation expense, related to unvested RSAs. This cost is expected to be recognized over a weighted average period of 3.3 years as of June 30, 2015. The weighted average remaining contractual term for RSAs as of June 30, 2015 was 3.3 years.

Equity Plans

The Company maintains two equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”) and the 2013 Omnibus Incentive Plan (the “2013 Equity Plan”), which was amended and restated as the Aerie Pharmaceuticals, Inc. Amended and Restated Omnibus Incentive Plan (the “Amended and Restated Equity Plan”). The 2005 Plan and the Amended and Restated Equity Plan are referred to collectively as the “Plans.”

On October 30, 2013, the effective date of the 2013 Equity Plan, the 2005 Plan was frozen and no additional awards will be made under the 2005 Plan. Any shares remaining available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan.

At the 2015 Annual Meeting of Stockholders held on April 10, 2015, the Company’s stockholders approved the adoption of the Amended and Restated Equity Plan and no additional awards will be made under the 2013 Equity Plan. Any shares remaining available under the 2013 Equity Plan were allocated to the Amended and Restated Equity Plan.

The Amended and Restated Equity Plan provides for the granting of up to 5,729,068 equity awards in respect of common stock of the Company, including equity awards that were available for issuance under the 2013 Equity Plan. The Company granted stock options to employees to purchase 921,400 and 1,143,700 shares of common stock during the six months ended June 30, 2015 and 2014, respectively. The Company granted 99,027 RSAs to employees during the six months ended June 30, 2015. No RSAs were granted by the Company during the six months ended June 30, 2014.

Options outstanding at June 30, 2015	4,601,831		$	12.14	$	25,356
Options exercisable at June 30, 2015	1,962,997		$	6.45	$	21,986

The following table summarizes the RSA activity under the Plans:

	NUMBER OF SHARES		WEIGHTED AVERAGE FAIR VALUE PER SHARE
RSAs outstanding at December 31, 2014	103,064		$	2.47
Granted	99,027		28.00
Vested	(46,539	)	2.74
Canceled	(1,538	)	32.30
RSAs outstanding at June 30, 2015	154,014		$	18.50

The vesting of the RSAs is time and service based with terms of two to four years. The RSAs are subject to repurchase, such that the Company has the right, but not the obligation, to repurchase unvested shares upon the employee’s termination.

12. Commitments and Contingencies

Litigation

The Company may periodically become subject to legal proceedings and claims arising in connection with its business. Except as set forth below, the Company is not a party to any known litigation, is not aware of any unasserted claims and does not have contingency reserves established for any litigation liabilities.

 A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey on April 29, 2015, on behalf of a purported class of persons and entities who purchased or otherwise acquired the Company’s publicly traded securities between August 6, 2014 and April 23, 2015. The complaint asserts claims under the Securities Exchange Act of 1934 and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of the Company’s initial Phase 3 registration trial of Rhopressa^TM, named “Rocket 1,” and Rhopressa^TM.

The Company believes that the claims asserted in the action are without merit and intends to defend the lawsuit vigorously, and the Company expects to incur costs associated with defending the action. In addition, the Company has various insurance policies related to the risks associated with its business, including directors’ and officers’ liability insurance policies. However, there is no assurance that the Company will be successful in its defense of the action, and there is no assurance that the Company’s insurance coverage, which contains a self-insured retention, will be sufficient or that its insurance carriers will cover all claims or litigation costs. At this time, the Company cannot accurately predict the ultimate outcome of this matter. Due to the inherent uncertainties of litigation, the Company cannot reasonably predict the timing or outcomes, or estimate the amount of loss, or range of loss, if any, or their effect, if any, on the Company’s financial statements.

14

Contract Service Providers

In the course of the Company’s normal business operations, it has agreements with contract service providers to assist in the performance of its research and development, clinical research and manufacturing activities. Substantially all of these contracts are on an as-needed basis.

13. Subsequent Events

On August 4, 2015, the Company and GrayBug, Inc. (“GrayBug”) entered into a research collaboration and license agreement to deliver certain of the Company’s preclinical stage product candidates to both the front and back of the eye using GrayBug’s proprietary technology. The Board of Directors of the Company and that of GrayBug have a common Board member.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following management’s discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and related notes that appear elsewhere in this report and with our audited financial statements and related notes and management’s discussion and analysis of financial condition and results of operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as filed with the SEC on February 27, 2015. This discussion and analysis contains forward-looking statements that involve risks and uncertainties. Please see “Special Note Regarding Forward-Looking Statements” for additional factors relating to such statements, and see “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and our Quarterly Report on Form 10-Q for the period ended March 31, 2015, as filed on May 7, 2015, for a discussion of certain risk factors applicable to our business, financial condition and results of operations. Past operating results are not necessarily indicative of operating results in any future periods.

Overview

We are a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with glaucoma and other diseases of the eye. Our lead product candidate, once-daily, triple-action Rhopressa^TM, successfully completed a Phase 2b clinical trial in patients with open-angle glaucoma and ocular hypertension in May 2013. Phase 3 registration trials commenced in July 2014 and we completed our initial Phase 3 registration trial, named “Rocket 1,” which was designed to measure efficacy over three months. The Rocket 1 trial did not meet its primary efficacy endpoint of demonstrating non-inferiority of IOP lowering for once-daily Rhopressa^TM compared to twice-daily timolol. We evaluated the data and results from Rocket 1 and obtained agreement from the U.S. Food and Drug Administration (“FDA”) to change the IOP range used for the primary endpoint of our second Phase 3 registration trial, named “Rocket 2.” Rocket 2 is designed to measure efficacy over three months and assess safety over 12 months. The modified clinical endpoint range for Rocket 2 was set to a level where Rocket 1 would have been successful. Three-month efficacy results for Rocket 2 are expected in September 2015. In addition, we are currently conducting a one year, safety-only study in Canada, named “Rocket 3,” and will conduct an additional Phase 3 registration trial for Rhopressa^TM, “Rocket 4,” which we plan to commence in the United States in the third quarter of 2015.

Our second product candidate, once-daily, quadruple-action Roclatan^TM, which is a fixed-dose combination of Rhopressa^TM and latanoprost, the most commonly prescribed drug for the treatment of patients with glaucoma, successfully completed a Phase 2b clinical trial in patients with open-angle glaucoma and ocular hypertension in June 2014. We expect the first Phase 3 registration trial, named “Mercury 1,” to commence in the third quarter of 2015. Preparatory steps for this trial are underway.

We are developing Rhopressa^TM as the first of a new class of compounds that is designed to lower intraocular pressure, or IOP, through novel biochemical targets. By inhibiting these targets, we believe Rhopressa^TM reduces IOP via three separate mechanisms of action, or MOAs: (i) it increases fluid outflow through the trabecular meshwork, the diseased tissue of the eye, (ii) it reduces episcleral venous pressure, which represents the pressure of the blood in the episcleral veins of the eye where eye fluid drains into the bloodstream, and (iii) it reduces the production of eye fluid. Roclatan^TM is a combination of Rhopressa^TM and latanoprost and is designed to lower IOP through the same three MOAs as Rhopressa^TM and, with a fourth MOA, through the ability of latanoprost to increase fluid outflow through the uveoscleral pathway, the eye’s secondary drain.

Our stated objective is to build a major ophthalmic pharmaceutical company. In addition to our primary product candidates, Rhopressa^TM and Roclatan^TM, we are also exploring the longer-term impact of Rhopressa^TM on the diseased trabecular meshwork as well as neuroprotection, and evaluating possible uses of our existing proprietary portfolio of Rho Kinase inhibitors beyond glaucoma. In February 2015, we issued a research update on preclinical results demonstrating the potential for Rhopressa^TM to have disease-modifying activity in glaucoma by stopping fibrosis in the trabecular meshwork, and also increasing perfusion in the trabecular outflow pathway thus increasing the delivery of nutrients to the diseased tissue. Additionally, an early-stage molecule, AR-13154, has shown preclinically the potential to decrease lesions in wet age-related macular degeneration at numerically higher levels than current market leading products. Our strategy includes developing our business outside of North America, including potentially obtaining clinical approval on our own for our lead compounds in Europe and possibly Japan. Regarding commercialization strategy, if our products are successful, we may potentially commercialize ourselves or with a partner in Europe, and likely with a partner in Japan.

In March 2015, we revised our corporate structure to align with our business strategy outside of North America by establishing Aerie Pharmaceuticals Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands (“Aerie Limited”). In addition, we assigned the beneficial rights to our non-U.S. and Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, we and Aerie Limited entered into a research and development and cost sharing agreement pursuant to which we and Aerie Limited will share the costs of the development of intellectual property. Additionally, in April 2015, we continued to prepare for foreign-based activities and established Aerie Pharmaceuticals Ireland

16

Limited (“Aerie Ireland Limited”) as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited.

We may license, acquire or develop additional product candidates to broaden our presence in ophthalmology. In August 2015, we entered into a collaboration and license arrangement with GrayBug, Inc. We continually explore and discuss additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners.

We have incurred net losses since our inception in June 2005. Our operations to date have been limited to research and development and raising capital. As of June 30, 2015, we had an accumulated deficit of $179.2 million. We recorded net losses of $18.8 million and $36.0 million for the three and six months endedJune 30, 2015, respectively, and net losses of $11.8 million and $18.5 million for the three and six months endedJune 30, 2014, respectively. We anticipate that a substantial portion of our capital resources and efforts in the foreseeable future will be focused on completing the development and obtaining regulatory approval and preparing for potential commercialization of our product candidates.

We expect our research and development expenses to increase as we continue to initiate and conduct clinical trials for our Rhopressa™ and Roclatan™ product candidates and pursue regulatory approval. As we prepare for commercialization, we will likely incur significant commercial, sales, marketing and outsourced manufacturing expenses. Since our initial public offering (“IPO”) in October 2013, we are also incurring additional expenses associated with operating as a public company. As a result, we expect to continue to incur significant and increasing operating losses at least for the next several years.

Prior to our IPO, we raised net cash proceeds of $78.6 million from the private placement of $43.8 million of convertible preferred stock and $34.8 million of convertible notes. Subsequent to the issuance of the convertible notes, we made $0.5 million in cash payments, $16.2 million of the convertible notes were converted into shares of convertible preferred stock, which were subsequently converted into shares of common stock in connection with our IPO, and $18.0 million of convertible notes initially sold in 2012 were converted into shares of common stock in connection with our IPO. In connection with our IPO, all outstanding shares of convertible preferred stock were converted into shares of common stock.

On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. Our shares began trading on the NASDAQ Global Market on October 25, 2013. We received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million.

On September 30, 2014, we issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”). We received net proceeds from the issuance of the 2014 Convertible Notes of approximately $124.1 million, after deducting discounts and certain expenses of $875,000.

On November 3, 2014, we filed a shelf registration statement on Form S-3, which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale by us of up to a maximum aggregate offering price of $150.0 million of our common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by us under the “at-the-market” sales agreement is included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement. As of and for the six months ended June 30, 2015, we issued and sold 1,224,548 shares of our common stock under the “at-the-market” sales agreement. We received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million.

Proceeds from the “at-the-market” sales, the 2014 Convertible Notes financing in September 2014 and our IPO in October 2013, are currently expected to provide sufficient resources to complete all currently known non-clinical and clinical requirements for our development programs advancing Rhopressa^TM and Roclatan^TM, and approval by the FDA and product commercialization, pending successful outcome of the trials. We also intend to use the proceeds in part for general corporate purposes and potentially for strategic growth opportunities.

To date, we have not generated product revenue and we do not expect to generate product revenue unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates. If we do not successfully commercialize any of our product candidates, we may be unable to generate product revenue or achieve profitability.

17

We may be required to obtain further funding through public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our research and development programs or commercialization efforts.

Financial Overview

Revenue

We have not generated any revenue from the sale of any products, and we do not expect to generate any revenue unless or until we obtain regulatory approval of and commercialize our products.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries, benefits and stock-based compensation for all officers and employees in general management, finance and administration. Other significant expenses include facilities expenses and professional fees for accounting, legal and other services.

We expect that our general and administrative expenses will increase with the continued advancement of our product candidates and with our increased management, legal, compliance, accounting and investor relations expenses as we continue to grow. We expect these increases will likely include higher expenses for insurance, expenses related to the hiring of additional personnel and payments to outside service providers, lawyers and accountants.

Research and Development Expenses

Since our inception, we have focused on our development programs. Research and development expenses consist primarily of costs incurred for the research and development of our preclinical and clinical candidates, which include:

• employee-related expenses, including salaries, benefits, travel and stock-based compensation expense for research and development personnel;

• expenses incurred under agreements with contract research organizations (“CROs”), contract manufacturing organizations and service providers that assist in conducting clinical trials and preclinical studies;

• costs associated with preclinical activities and development activities;

• costs associated with regulatory operations; and

• depreciation expense for assets used in research and development activities.

We expense research and development costs to operations as incurred. The costs for certain development activities, such as clinical trials, are recognized based on the terms of underlying agreements as well as an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations along with additional information provided to us by our vendors.

Expenses relating to activities, such as manufacturing and stability and toxicology studies, that are supportive of the product candidate itself, are classified as direct non-clinical. Expenses relating to clinical trials and similar activities, including costs associated with CROs, are classified as direct clinical. Expenses relating to activities that support more than one development program or activity such as personnel costs, stock-based compensation and depreciation are not allocated to direct clinical or non-clinical expenses and are separately classified as “unallocated.”

18

The following table shows our research and development expenses by product candidate and type of activity for the three and six months endedJune 30, 2015 and 2014:

	THREE MONTHS ENDED   JUNE 30,				SIX MONTHS ENDED   JUNE 30,

Total research and development expense	$	10,627	$	6,676	$	22,245	$	12,046

For the periods presented, we did not incur significant direct non-clinical or direct clinical costs for our exploration of the longer-term impact of Rhopressa^TM on the diseased trabecular meshwork and neuroprotection or for possible uses of our existing proprietary portfolio of Rho Kinase inhibitors beyond glaucoma. Costs for these activities were primarily comprised of internal personnel costs and were included in unallocated costs. Discontinued product candidates relate to previously developed AR-12286 and related compounds for which further development for the treatment of glaucoma was discontinued in 2013.

Research and development activities associated with the discovery and development of new drugs and products for the treatment of diseases of the eye are central to our business model. 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 as we continue to conduct clinical trials for our product candidates, or if the FDA requires us to conduct additional trials for approval.

Our research and development expenditures are subject to numerous uncertainties in timing and cost to completion. Development timelines, the probability of success and development expenses can differ materially from expectations. The cost of clinical trials may vary significantly over the life of a project as a result of differences arising during clinical development, including, among others, the following:

• number of trials required for approval;

• number of sites included in the trials;

• length of time required to enroll suitable patients;

• number of patients that participate in the trials;

• drop-out or discontinuation rates of patients;

• duration of patient follow-up;

• costs related to compliance with regulatory requirements;

• number and complexity of analyses and tests performed during the trial;

• phase of development of the product candidate; and

• efficacy and safety profile of the product candidate.

19

Our expenses related to clinical trials are based on estimates of patient enrollment and related expenses at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with research institutions, consultants and CROs that assist in conducting and managing our clinical trials. We generally accrue expenses related to clinical trials based on contracted amounts applied to the level of patient enrollment and activity according to the protocol. If future timelines or contracts are modified based upon changes in the clinical trial protocol or scope of work to be performed, we modify our estimates of accrued expenses accordingly on a prospective basis. Historically, such modifications have not been material.

As a result of the uncertainties discussed above, we are unable to determine with certainty the duration and completion costs of our development programs or precisely when and to what extent we will receive revenue from the commercialization and sale of our products. We may never succeed in achieving regulatory approval for one or more of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of future preclinical studies and clinical trials, uncertainties in the clinical trial enrollment rate and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including efficacy and tolerability profiles, manufacturing capability, competition, and commercial viability.

Other Income (Expense), Net

Other income consists of interest earned on our cash and cash equivalents and investments as well as the net proceeds from the sale of our net operating loss tax benefits for the state of New Jersey. Refer to Note 3 to our unaudited consolidated financial statements appearing elsewhere in this report for further information.

Other expense consists of interest expense under the 2014 Convertible Notes, amortization of debt discounts and other miscellaneous expense.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, costs and expenses and related disclosures. We evaluate our estimates and judgments on an ongoing basis. Significant estimates include assumptions used in the determination of stock-based compensation and certain research and development expenses. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are more fully described in Note 2 to our unaudited consolidated financial statements included elsewhere in this report and Note 2 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014.

General and administrative expenses

General and administrative expenses increased by $2.3 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014. This increase was primarily associated with the expansion of our employee base to support the growth of our operations. Personnel costs increased by $1.2 million, including employee stock-based compensation expense of $0.7 million and new salaried employees and related expenses of $0.5 million. As a result of the IP Assignment and other business related activities in connection with operating as a public company, travel expenses increased by $0.5 million and outside professional fees increased by $0.4 million.

Research and development expenses

During the three months ended June 30, 2015, our research and development activity was primarily associated with Phase 3 clinical trials for Rhopressa™ and preparatory activities for our Phase 3 clinical trials for Roclatan™. Research and development expenses increased by $4.0 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014. Costs for Rhopressa™ increased by $1.7 million as direct clinical costs increased by $2.4 million and direct non-clinical costs decreased by $0.8 million. Costs for Roclatan™ increased by $0.5 million as direct non-clinical costs increased by $0.8 million and direct clinical costs decreased by $0.3 million as a result of our preparatory activities for our Phase 3 clinical trials and completion of our Phase 2b clinical trial in 2014. Additionally, unallocated expenses, including employee salary, consulting costs and related expenses, increased by $1.8 million.

Other income (expense), net

Other income (expense), net decreased by $0.5 million for the three months ended June 30, 2015 as compared to the three months ended June 30, 2014. The decrease was mainly due to an increase in interest and amortization expense of $0.6 million.

21

Comparison of the Six Months Ended June 30, 2015 and 2014

The following table summarizes the results of our operations for the six months ended June 30, 2015 and 2014:

	SIX MONTHS ENDED   JUNE 30,						INCREASE			% INCREASE

Net loss before income taxes	$	(35,873	)	$	(18,485	)

General and administrative expenses

General and administrative expenses increased by $6.7 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014. This increase was primarily associated with the expansion of our employee base to support the growth of our operations. Personnel costs increased by $2.8 million, including employee stock-based compensation expense of $1.7 million and new salaried employees and related expenses of $1.1 million. As a result of the IP Assignment and other business related activities in connection with operating as a public company, outside professional fees increased by $2.5 million and travel expenses increased by $0.8 million.

Research and development expenses

During the six months ended June 30, 2015, our research and development activity was primarily associated with Phase 3 clinical trials for Rhopressa™ and preparatory activities for our Phase 3 clinical trials for Roclatan™. Research and development expenses increased by $10.2 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014. Costs for Rhopressa™ increased by $6.6 million as direct clinical costs increased by $7.7 million and direct non-clinical costs decreased by $1.0 million. Costs for Roclatan™ decreased by $0.2 million as direct clinical costs decreased by $1.3 million and direct non-clinical costs increased by $1.1 million as a result of our completion of a Phase 2b clinical trial in 2014 and preparatory activities for our Phase 3 clinical trials. Additionally, unallocated expenses including employee salary, consulting costs and related expenses, increased by $3.7 million.

Other income (expense), net

Other income (expense), net decreased by $0.4 million for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014. The decrease was mainly due to an increase in interest and amortization expense of $1.2 million partially offset by an increase in income of $0.8 million related to the sale of deferred state tax benefits to unrelated third parties and an increase in investment income.

Liquidity and Capital Resources

Since our inception, we have funded operations primarily through the sale of equity securities, including our IPO, and the issuance of convertible notes. We have incurred losses and experienced negative operating cash flows since our inception and anticipate that we will continue to incur losses for at least the next several years.

Prior to our IPO, we raised net cash proceeds of $78.6 million from the private placement of $43.8 million of convertible preferred stock and $34.8 million of convertible notes. Subsequent to their issuance, we paid $0.5 million in cash payments on the convertible notes, $16.2 million of the convertible notes were converted into shares of convertible preferred stock, which were subsequently converted into shares of common stock in connection with our IPO, and $18.0 million of convertible notes initially sold in 2012 were converted into shares of common stock in connection with our IPO. In connection with our IPO, all outstanding shares of convertible preferred stock were converted into shares of common stock.

22

On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. We received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million.

On September 30, 2014, we issued $125.0 million aggregate principal amount of 2014 Convertible Notes. We received net proceeds from the issuance of the 2014 Convertible Notes of approximately $124.1 million, after deducting discounts and certain expenses of $875,000.

On November 3, 2014, we filed a shelf registration statement on Form S-3, which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale by us of up to a maximum aggregate offering price of $150.0 million of our common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by us under the “at-the-market” sales agreement is included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement. As of and for the six months ended June 30, 2015, we issued and sold 1,224,548 shares of our common stock under the “at-the-market” sales agreement. We received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million.

As of June 30, 2015, our principal sources of liquidity were our cash and cash equivalents and investments, which totaled approximately $162.9 million.

We currently estimate that our cash and cash equivalents and investments as of June 30, 2015 will provide sufficient resources to complete all currently known non-clinical and clinical requirements for our development programs advancing Rhopressa™ and Roclatan™, and approval by the FDA and product commercialization, pending successful outcome of the trials. Our ability to continue as a going concern will depend, in large part, on our ability to successfully commercialize our product candidates and generate positive cash flow from operations, neither of which is certain.

The following table summarizes our sources and uses of cash:

	SIX MONTHS ENDED   JUNE 30,
	2015			2014
	(unaudited) (in thousands)
Net cash (used in) provided by:
Operating activities	$	(29,588	)	$	(12,921	)
Investing activities	9,310			(28,926		)
Financing activities	35,608			74
Net change in cash and cash equivalents	$	15,330		$	(41,773	)

During the six months ended June 30, 2015 and 2014, our operating activities used net cash of $29.6 million and $12.9 million, respectively. The use of net cash in each of these periods primarily resulted from our net losses, adjusted for certain non-cash items. The increase in net loss from operations for the six months ended June 30, 2015 as compared to the six months ended June 30, 2014 was due to increases in general and administrative and research and development expenses as previously described, see “—Results of Operations.” For the six months ended June 30, 2015 and 2014, we received $2.9 million and $2.3 million, respectively, of cash proceeds from the sale of deferred state tax benefits to unrelated parties, which decreased net cash used in operating activities.

During the six months ended June 30, 2015, our investing activities provided net cash of $9.3 million primarily related to maturities of available-for-sale investments of $24.1 million, which was partially offset by purchases of available-for-sale investments of $14.0 million and by purchases of office furnishings, software and equipment of $1.1 million to facilitate our increased research and development and corporate activities. During the six months ended June 30, 2014, our investing activities used net cash of approximately $28.9 million primarily related to purchases of available-for-sale investments, which was partially offset by maturities of available-for-sale investments of $3.0 million.

23

During the six months ended June 30, 2015 and 2014, our financing activities provided net cash of $35.6 million and $0.1 million, respectively. The net cash provided by financing activities during the six months ended June 30, 2015 was primarily related to the issuance and sale of common stock under the “at-the-market” sales agreement pursuant to our shelf registration statement. We received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million. The net cash provided by financing activities during the six months ended June 30, 2014 was related to proceeds of approximately $0.1 million from exercise of stock purchase rights under our employee stock purchase plan.

Operating Capital Requirements

We expect to incur increasing operating losses for at least the next several years as we continue to conduct Phase 3 clinical trials for Rhopressa^TM and initiate and complete for Phase 3 clinical trials for Roclatan^TM. We currently expect that our existing cash and cash equivalents and investments will provide sufficient resources to complete all currently known non-clinical and clinical requirements for our development programs advancing Rhopressa™ and Roclatan™, and approval by the FDA and product commercialization, pending successful outcome of the trials.

We expect to continue to incur increasing costs associated with the growth of our operations, including but not limited to, increased costs and expenses for directors fees associated with the expansion of our board, increased personnel costs, increased business development activities, increased directors and officers insurance premiums, audit and legal fees, investor relations fees, expenses for compliance with reporting requirements under the Exchange Act and rules implemented by the SEC and NASDAQ and various other costs.

Due to the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. We based our projections on assumptions that may prove to be incorrect or unreliable or may change due to circumstances beyond our control, and as a result we may consume our available capital resources earlier than we originally projected. Our future funding requirements will depend on many factors, including, but not limited to the following:

• timing and costs of our future preclinical studies and clinical trials for our product candidates;

• costs of any follow-on development or products;

• timing and cost of the ongoing supportive preclinical studies and activities for our product candidates;

• outcome, timing and costs of seeking regulatory approval;

• costs of commercialization activities for our product candidates, if we receive regulatory approval, including the costs and timing of establishing product sales, marketing, manufacturing and distribution capabilities;

• costs of operating as a public company, including legal, compliance, accounting and investor relations expenses;

• terms and timing of any future collaborations, licensing, consulting or other arrangements that we may establish; and

• filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against intellectual property related claims.

We may need to obtain additional financing to fund our future operations, including supporting our international operations and sales and marketing activities, as well as funding the ongoing development of any additional product candidates we might license, acquire or develop internally. To the extent that we raise additional capital through the sale of common stock, convertible securities or other equity securities, the ownership interests of our existing stockholders may be materially diluted and the terms of these securities could include liquidation or other preferences that could adversely affect the rights of our existing stockholders. If we are unable to raise capital when needed or on acceptable terms, we could be forced to delay, reduce or discontinue our research and development programs or commercialization efforts.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations at June 30, 2015:

	TOTAL		LESS THAN 1 YEAR		1 TO 3 YEARS		3 TO 5 YEARS		MORE THAN 5 YEARS
(in thousands)
Operating lease obligations(1)	$	7,513	$	1,055	$	2,518	$	2,746	$	1,194
2014 Convertible Notes(2)	125,000		—		—		—		125,000
	132,513		1,055		2,518		2,746		126,194

(1) Our operating lease obligations are primarily related to our principal executive offices in Irvine, California, corporate offices in New Jersey and research facility in North Carolina.

(2) On September 30, 2014, we issued the 2014 Convertible Notes to Deerfield Partners, L.P., Deerfield International Master Fund, L.P., Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. and Deerfield Special Situations International Master Fund, L.P. The 2014 Convertible Notes mature on the seventh anniversary from the date of issuance, unless earlier converted. On January 1, 2015, Deerfield Special Situations International Master Fund, L.P. transferred all of its rights under the 2014 Convertible Notes to Deerfield Special Situations Fund, L.P. Refer to Note 8 to our unaudited consolidated financial statements appearing elsewhere in this report for further information.

We have no other contractual obligations or commitments that are not subject to our existing financial statement accrual processes.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements as defined under SEC rules.

Jumpstart Our Business Startups Act of 2012

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) provides that an emerging growth company can take advantage of certain exemptions from various reporting and other requirements that are applicable to public companies that are not emerging growth companies. We currently take advantage of some, but not all, of the reduced regulatory and reporting requirements that are available to us for as long as we qualify as an emerging growth company. We have irrevocably elected under Section 107 of the JOBS Act not to take advantage of the extension of time to comply with new or revised financial accounting standards available under Section 102(b) of the JOBS Act and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Our independent registered public accounting firm will not be required to provide an attestation report on the effectiveness of our internal control over financial reporting for as long as we qualify as an emerging growth company.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. Our cash and cash equivalents as of June 30, 2015, totaled $100.9 million and consisted of cash and money market funds with original maturities of three months or less from the date of purchase. Our investments totaled $62.0 million as of June 30, 2015 and consisted of certificates of deposit, commercial paper, corporate bonds and government agency securities. We had cash and cash equivalents and investments of $158.2 million as of December 31, 2014. Given the short-term nature of our cash equivalents and investments and our investment policy, a sudden change in market interest rates would not be expected to have a material impact on our financial condition or results of operations. We do not engage in any hedging activities against changes in interest rates. The 2014 Convertible Notes carry a fixed interest rate and, as such, are not subject to interest rate risk. We do not have any foreign currency or other derivative financial instruments.

25

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15(d)-15(e)), as of the end of the period covered by this report. Based upon the evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2015, the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act, is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, 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 benefits of possible controls and procedures relative to their costs.

Changes in Internal Control Over Financial Reporting

There have been no significant changes in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We may periodically become subject to legal proceedings and claims arising in connection with our business. Except as set forth below, we are not a party to any known litigation, are not aware of any unasserted claims and do not have contingency reserves established for any litigation liabilities.

A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against us and certain of our officers and directors in the United States District Court for the District of New Jersey on April 29, 2015, on behalf of a purported class of persons and entities who purchased or otherwise acquired our publicly traded securities between August 6, 2014 and April 23, 2015. The complaint asserts claims under the Exchange Act and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of Rocket 1 and Rhopressa^TM.

We believe that the claims in the asserted action are without merit and intend to defend the lawsuit vigorously, and we expect to incur costs associated with defending the action. In addition, we have various insurance policies related to the risks associated with our business, including directors’ and officers’ liability insurance policies. However, there is no assurance that we will be successful in our defense of the action, and there is no assurance that our insurance coverage, which contains a self-insured retention, will be sufficient or that our insurance carriers will cover all claims or litigation costs. At this time, we cannot accurately predict the ultimate outcome of this matter. Due to the inherent uncertainties of litigation, we cannot reasonably predict the timing or outcomes, or estimate the amount of loss, or range of loss, if any, or their effect, if any, on our financial statements.

Item 1A. Risk Factors

You should consider carefully the risks set forth under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on February 27, 2015, as supplemented and updated by the risks set forth under "Risk Factors" in our Quarterly Report on Form 10-Q for the period ended March 31, 2015, filed with the SEC on May 7, 2015.

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

Unregistered Sales of Equity Securities

None.

Use of Proceeds from Registered Securities

On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The shares were registered under the Securities Act on a registration statement on Form S-1 (Registration No. 333-191219). The SEC declared the registration statement effective on October 24, 2013.

We have invested the net proceeds from the IPO in a variety of capital preservation investments, including short-term and long-term, investment grade, interest bearing instruments. There has been no material change in our planned use of the net proceeds from our IPO as described in our final prospectus filed with the SEC on October 28, 2013 pursuant to Rule 424(b) under the Securities Act.

On November 3, 2014, we filed a shelf registration statement on Form S-3 (Registration No. 333-199821), which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale by us of up to a maximum aggregate offering price of $150.0 million of our common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by us under the “at-the-market” sales agreement is included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement.

During the six months ended June 30, 2015, we issued and sold 1,224,548 shares of our common stock under the “at-the-market” sales agreement. We received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million.

27

We currently hold the net proceeds from the “at-the-market” sales as cash deposits and intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities. There has been no material change in our planned use of the net proceeds as described in our shelf registration statement filed on November 3, 2014.

Item 3. Defaults Upon Senior Securities

The Company

The Company

Aerie Pharmaceuticals, Inc. (“Aerie”), with its wholly-owned subsidiaries Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Limited” and “Aerie Ireland Limited”, respectively, together with Aerie, the “Company”), is a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of topical, small molecule products to treat patients with glaucoma and other diseases of the eye. The Company has its principal executive offices in Irvine, California and operates as one business segment.

The Company has not yet commenced commercial operations and therefore has not generated product revenue. The Company’s activities since inception primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company does not expect to generate revenue until and unless it receives regulatory approval of and successfully commercializes its product candidates. The Company has incurred losses and experienced negative operating cash flows since inception.

The Company has funded its operations primarily through the sale of equity securities and issuance of convertible notes. In October 2013, the Company completed its initial public offering (“IPO”) and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. On September 30, 2014, the Company issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”). The Company received net proceeds from the issuance of the 2014 Convertible Notes of approximately $124.1 million, after deducting discounts and certain expenses of $875,000. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

On November 3, 2014, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale of up to a maximum aggregate offering price of $150.0 million of the Company’s common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock that may be issued and sold under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by the Company under the “at-the-market” sales agreement is included in the $150.0 million of common stock that may be offered, issued and sold by the Company under the shelf registration statement. As of and for the six months ended June 30, 2015, the Company issued and sold 1,224,548 shares of its common stock under the “at-the-market” sales agreement. The Company received net proceeds of approximately $35.4 million, after deducting commissions of approximately $1.0 million.

In March 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands. In addition, Aerie assigned the beneficial rights to its non-U.S. and Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, Aerie and Aerie Limited entered into a research and development cost sharing agreement pursuant to which Aerie and Aerie Limited will share the costs of the development of intellectual property. Refer to Note 9 for a description of the tax impact of the IP Assignment. Additionally, in April 2015, the Company continued to prepare for foreign-based activities and established Aerie Ireland Limited as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited.

If the Company does not successfully commercialize any of its product candidates, it may be unable to generate product revenue or achieve profitability. Accordingly, the Company may be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or commercialization efforts. The Company currently estimates that it has sufficient funding to sustain operations through product commercialization of Rhopressa™ and Roclatan™, pending successful outcome of their clinical trials and U.S. Food and Drug Administration (“FDA”) approval.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of Presentation

The Company’s interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K. The results for the three and six months endedJune 30, 2015 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Principles of Consolidation

The interim consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of certificates of deposit, commercial paper, corporate bonds and government agency securities that are classified as available-for-sale in accordance with ASC 320, Investments—Debt and Equity Securities. The Company classifies investments available to fund current operations as current assets on its consolidated balance sheets. Investments are classified as long-term assets on the consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s consolidated balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three and six months endedJune 30, 2015 or 2014.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2015, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.

Deferred Financing Costs

Deferred financing costs consist of financing costs incurred by the Company in connection with the closing of Aerie’s 2014 Convertible Notes and are included in Other assets. The Company amortizes deferred financing costs through the earlier of maturity or the conversion of the 2014 Convertible Notes using the effective interest method. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

Fair Value Measurements

The Company records certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair value of the Company’s financial instruments, including cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses approximate their respective carrying values due to the short-term nature of these instruments. The carrying amounts of long-term investments represent their estimated fair values. The estimated fair value of Aerie’s 2014 Convertible Notes was $111.1 million and $163.8 million as of June 30, 2015 and December 31, 2014, respectively. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on June 30, 2015 as compared to December 31, 2014. As of June 30, 2015 and December 31, 2014, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets.

Software Capitalization

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software including external direct costs of materials and services involved with the software development. Capitalized software costs are included in Furniture, fixtures, and equipment and are amortized beginning when the software project is substantially complete and the asset is ready for its intended use. Costs incurred during the preliminary project stage and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (the “FASB”) issued ASU 2015-03, which simplifies the presentation of debt issuance costs. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2015, with early adoption permitted. Upon adoption of ASU 2015-03, the Company will present debt issuance costs as a direct reduction to the debt liability rather than as an asset on its consolidated balance sheets.

In August 2014, the FASB issued ASU 2014-15, which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for the Company for the annual period ending after December 15, 2016 and for annual and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements.

Net Loss per Share Attributable to Common Stock

Basic net loss per share attributable to common stock (“Basic EPS”) is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration, and shares that are unequivocally issuable under the Company’s equity compensation plans and are therefore included in the calculation of the weighted-average number of shares of common stock as common stock equivalents. Diluted net loss per share attributable to common stock (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss attributable to common stockholders used in calculating Basic EPS is adjusted for certain items related to the dilutive securities.

For all periods presented, the Company’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have the effect of reducing the net loss per share of common stock. Therefore, the denominator used to calculate Basic EPS and Diluted EPS is the same in all periods presented.

The Company’s potential common stock equivalents that have been excluded from the computation of Diluted EPS for all periods presented consist of the following:

In addition to the common stock equivalents presented above, the 2014 Convertible Notes provide for an increase in the conversion rate if conversion is elected in connection with a significant corporate transaction. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

Litigation

The Company may periodically become subject to legal proceedings and claims arising in connection with its business. Except as set forth below, the Company is not a party to any known litigation, is not aware of any unasserted claims and does not have contingency reserves established for any litigation liabilities.

 A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey on April 29, 2015, on behalf of a purported class of persons and entities who purchased or otherwise acquired the Company’s publicly traded securities between August 6, 2014 and April 23, 2015. The complaint asserts claims under the Securities Exchange Act of 1934 and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of the Company’s initial Phase 3 registration trial of Rhopressa^TM, named “Rocket 1,” and Rhopressa^TM.

The Company believes that the claims asserted in the action are without merit and intends to defend the lawsuit vigorously, and the Company expects to incur costs associated with defending the action. In addition, the Company has various insurance policies related to the risks associated with its business, including directors’ and officers’ liability insurance policies. However, there is no assurance that the Company will be successful in its defense of the action, and there is no assurance that the Company’s insurance coverage, which contains a self-insured retention, will be sufficient or that its insurance carriers will cover all claims or litigation costs. At this time, the Company cannot accurately predict the ultimate outcome of this matter. Due to the inherent uncertainties of litigation, the Company cannot reasonably predict the timing or outcomes, or estimate the amount of loss, or range of loss, if any, or their effect, if any, on the Company’s financial statements.

Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2015

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Company’s interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K. The results for the three and six months endedJune 30, 2015 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Principles of Consolidation

Principles of Consolidation

The interim consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of certificates of deposit, commercial paper, corporate bonds and government agency securities that are classified as available-for-sale in accordance with ASC 320, Investments—Debt and Equity Securities. The Company classifies investments available to fund current operations as current assets on its consolidated balance sheets. Investments are classified as long-term assets on the consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s consolidated balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three and six months endedJune 30, 2015 or 2014.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2015, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.

Deferred Financing Costs

Deferred Financing Costs

Deferred financing costs consist of financing costs incurred by the Company in connection with the closing of Aerie’s 2014 Convertible Notes and are included in Other assets. The Company amortizes deferred financing costs through the earlier of maturity or the conversion of the 2014 Convertible Notes using the effective interest method. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

Fair Value Measurements

Fair Value Measurements

The Company records certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair value of the Company’s financial instruments, including cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses approximate their respective carrying values due to the short-term nature of these instruments. The carrying amounts of long-term investments represent their estimated fair values. The estimated fair value of Aerie’s 2014 Convertible Notes was $111.1 million and $163.8 million as of June 30, 2015 and December 31, 2014, respectively. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on June 30, 2015 as compared to December 31, 2014. As of June 30, 2015 and December 31, 2014, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets.

Software Capitalization

Software Capitalization

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software including external direct costs of materials and services involved with the software development. Capitalized software costs are included in Furniture, fixtures, and equipment and are amortized beginning when the software project is substantially complete and the asset is ready for its intended use. Costs incurred during the preliminary project stage and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (the “FASB”) issued ASU 2015-03, which simplifies the presentation of debt issuance costs. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2015, with early adoption permitted. Upon adoption of ASU 2015-03, the Company will present debt issuance costs as a direct reduction to the debt liability rather than as an asset on its consolidated balance sheets.

In August 2014, the FASB issued ASU 2014-15, which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for the Company for the annual period ending after December 15, 2016 and for annual and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements.

Net Loss per Share Attributable to Common Stock

Net Loss per Share Attributable to Common Stock

Basic net loss per share attributable to common stock (“Basic EPS”) is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration, and shares that are unequivocally issuable under the Company’s equity compensation plans and are therefore included in the calculation of the weighted-average number of shares of common stock as common stock equivalents. Diluted net loss per share attributable to common stock (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss attributable to common stockholders used in calculating Basic EPS is adjusted for certain items related to the dilutive securities.

For all periods presented, the Company’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have the effect of reducing the net loss per share of common stock. Therefore, the denominator used to calculate Basic EPS and Diluted EPS is the same in all periods presented.

Debt Disclosure [Abstract]

Convertible Notes

Convertible Notes

On September 30, 2014, Aerie issued the 2014 Convertible Notes to Deerfield Partners, L.P., Deerfield International Master Fund, L.P., Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. and Deerfield Special Situations International Master Fund, L.P. (collectively, “Deerfield”). On January 1, 2015, Deerfield Special Situations International Master Fund, L.P. transferred all of its rights under the 2014 Convertible Notes to Deerfield Special Situations Fund, L.P.

The 2014 Convertible Notes bear interest at a rate of 1.75% per annum payable quarterly in arrears on the first business day of each January, April, July and October. The 2014 Convertible Notes mature on the seventh anniversary from the date of issuance, unless earlier converted.

The 2014 Convertible Notes constitute a senior secured obligation of Aerie, collateralized by a first priority security interest in substantially all of the assets of Aerie. The 2014 Convertible Notes provide that, upon the request of Aerie, Deerfield will release all of the liens on the collateral if both of the following occur: (i) beginning one month after FDA approval of either Rhopressa™ or Roclatan™, shares of Aerie’s common stock have traded at a price above $30 per share (subject to adjustment for any subdivision or combination of outstanding common stock) for 30 consecutive trading days, and (ii) Aerie is prepared to close a financing that will be secured by a lien on Aerie’s assets, subject only to the release of the lien on Aerie’s assets held by Deerfield.

In connection with the IP Assignment, Aerie granted Deerfield a security interest in an intercompany promissory note and pledged 65% of the voting stock of Aerie Limited. Upon the request of Aerie, Deerfield will release the lien on the intercompany promissory note under certain circumstances.

At closing, Aerie paid Deerfield a one-time transaction fee of $625,000. In addition, Aerie reimbursed Deerfield in the amount of $250,000 for certain expenses incurred by Deerfield in connection with the transaction. Aerie also incurred $1.3 million of legal and advisory fees in connection with the transaction.

The 2014 Convertible Notes are convertible at any time at the option of Deerfield, in whole or in part, into shares of common stock, including upon the repayment of the 2014 Convertible Notes at maturity (the “Conversion Option”). However, upon conversion, Deerfield (together with their affiliates) is limited to a 9.985% ownership cap in shares of common stock (the “9.985% Cap”). The 9.985% Cap would remain in place upon any assignment of the 2014 Convertible Notes by Deerfield.

The initial conversion price is $24.80 per share of common stock (equivalent to an initial conversion rate of 40.32 shares of common stock per $1,000 principal amount of 2014 Convertible Notes), representing a 30% premium over the closing price of the common stock on September 8, 2014. The conversion rate and the corresponding conversion price are subject to adjustment for stock dividends (other than a dividend for which Deerfield would be entitled to participate on an as-converted basis), stock splits, reverse stock splits and reclassifications. In addition, in connection with certain significant corporate transactions, Deerfield, at its option, may (i) require Aerie to prepay all or a portion of the principal amount of the 2014 Convertible Notes, plus accrued and unpaid interest, or (ii) convert all or a portion of the principal amount of the 2014 Convertible Notes into, depending upon the type of transaction, shares of common stock or the right to receive upon consummation of the transaction the consideration Deerfield would have received had Deerfield converted the 2014 Convertible Notes immediately prior to the consummation of the transaction. The 2014 Convertible Notes provide for an increase in the conversion rate if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction. The maximum increase to the initial conversion rate, in connection with a significant corporate transaction, is 12.07 shares of common stock per $1,000 principal amount of 2014 Conversion Notes, which decreases over time and is determined by reference to the price of the common stock prior to the consummation of the significant corporate transaction or the value of the significant corporate transaction.

The agreement governing the 2014 Convertible Notes contains various representations and warranties, and affirmative and negative covenants, customary for financings of this type, including restrictions on the incurrence of additional debt and liens on Aerie’s assets. As of June 30, 2015, Aerie was in compliance with the covenants. The agreement governing the 2014 Convertible Notes also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie; the suspension, cancellation or revocation of governmental authorizations that are reasonably expected to have a material adverse effect on Aerie’s business; the acceleration of a specified amount of indebtedness; and the failure to deliver shares of common stock upon conversion of the 2014 Convertible Notes. If any event of default were to occur, and continue beyond any applicable cure period, the holders of more than 50% of the aggregate principal amount of the then outstanding 2014 Convertible Notes would be permitted to declare the principal and accrued and unpaid interest to be immediately due and payable.

The Company recorded the 2014 Convertible Notes as long-term debt at face value less debt discounts relating to fees and certain expenses paid to Deerfield in connection with the transaction. The Conversion Option is a derivative that qualifies for an exemption from bifurcation and liability accounting as provided for in ASC Topic 815, Derivatives and Hedging – Contracts in Entity’s Own Equity (“ASC 815”). Since the Conversion Option is not bifurcated as a derivative pursuant to ASC 815, the Company further evaluated the Conversion Option to determine whether it is considered a beneficial conversion feature (“BCF”). The Company determined that the initial accounting conversion price was greater than the fair value of the common stock at the close of trading on the date of issuance, therefore no BCF existed at inception. However, if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction, the increase to the initial conversion rate may cause a contingent BCF to exist at the time of conversion. The contingent BCF, if any, will be recognized in earnings when the contingency is resolved and will be measured using the fair value of the common stock at the close of trading on the date of issuance and the accounting conversion price as adjusted for such an increase to the initial conversion rate.

As of June 30, 2015, the Company recognized unamortized debt discounts of $782,000. Debt discounts are amortized using the effective interest method through the earlier of maturity or the conversion of the 2014 Convertible Notes.

The table below summarizes the carrying value of the 2014 Convertible Notes as of June 30, 2015:

(in thousands)	JUNE 30, 2015
Gross proceeds	$	125,000
Initial value of issuance costs recorded as debt discount	(875		)
Amortization of debt discount	93
Carrying value	$	124,218

For the three and six months endedJune 30, 2015, interest expense related to the 2014 Convertible Notes was $545,000 and $1.1 million, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The IP Assignment resulted in the recognition of a taxable gain for U.S. federal and state income tax purposes. As of June 30, 2015, the estimated income tax liability was $8.7 million after utilization of net operating loss carry-forwards, current year losses generated through June 30, 2015 and quarterly estimated payments made through June 30, 2015. Under ASC 810, Consolidation, the income tax expense of $9.0 million for the six months ended June 30, 2015 was recorded as a prepaid asset. The income tax liability and prepaid asset are expected to be substantially reduced by current year losses projected after June 30, 2015. In accordance with ASC 810, Consolidation, the remaining estimated prepaid asset will be amortized into income tax expense over the estimated remaining patent life of the intellectual property subject to the IP Assignment, through approximately 2030.

As a result of the IP Assignment, the Company reversed approximately $40.8 million of its valuation allowance on certain deferred tax assets, primarily federal and state net operating losses, as of June 30, 2015. Due to the Company’s history of operating losses and lack of available evidence supporting future taxable income, the Company believes that a valuation allowance on its remaining deferred tax assets as of June 30, 2015 remains appropriate.

In addition, the IP Assignment is subject to complex tax and transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with the Company’s determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and the Company’s position were not sustained, the Company could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates and reduced cash flows than otherwise would be expected.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-based Compensation

Stock-based Compensation

Stock-based compensation expense for options granted and restricted stock awards (“RSAs”) is reflected in the consolidated statement of operations as follows:

	THREE MONTHS ENDED   JUNE 30,				SIX MONTHS ENDED   JUNE 30,
(in thousands)	2015		2014		2015		2014
Research and development	$	583	$	237	$	1,094	$	852
General and administrative	2,893		2,145		5,123		3,452
Total	$	3,476	$	2,382	$	6,217	$	4,304

The estimated fair value of options granted is determined on the date of grant using the Black-Scholes option pricing model. Options granted to non-employees are revalued at each financial reporting period until required service is performed. Compensation expense related to RSAs is based on the market value of the Company’s common stock on the date of grant and is expensed on a straight-line basis (net of estimated forfeitures) over the vesting period.

As of June 30, 2015, the Company had $31.4 million of unrecognized compensation expense related to options granted under its equity plans. This cost is expected to be recognized over a weighted average period of 2.8 years as of June 30, 2015. The weighted average remaining contractual life on all outstanding options as of June 30, 2015 was 8.3 years.

As of June 30, 2015, the Company had $2.4 million of unrecognized compensation expense, related to unvested RSAs. This cost is expected to be recognized over a weighted average period of 3.3 years as of June 30, 2015. The weighted average remaining contractual term for RSAs as of June 30, 2015 was 3.3 years.

Equity Plans

The Company maintains two equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”) and the 2013 Omnibus Incentive Plan (the “2013 Equity Plan”), which was amended and restated as the Aerie Pharmaceuticals, Inc. Amended and Restated Omnibus Incentive Plan (the “Amended and Restated Equity Plan”). The 2005 Plan and the Amended and Restated Equity Plan are referred to collectively as the “Plans.”

On October 30, 2013, the effective date of the 2013 Equity Plan, the 2005 Plan was frozen and no additional awards will be made under the 2005 Plan. Any shares remaining available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan.

At the 2015 Annual Meeting of Stockholders held on April 10, 2015, the Company’s stockholders approved the adoption of the Amended and Restated Equity Plan and no additional awards will be made under the 2013 Equity Plan. Any shares remaining available under the 2013 Equity Plan were allocated to the Amended and Restated Equity Plan.

The Amended and Restated Equity Plan provides for the granting of up to 5,729,068 equity awards in respect of common stock of the Company, including equity awards that were available for issuance under the 2013 Equity Plan. The Company granted stock options to employees to purchase 921,400 and 1,143,700 shares of common stock during the six months ended June 30, 2015 and 2014, respectively. The Company granted 99,027 RSAs to employees during the six months ended June 30, 2015. No RSAs were granted by the Company during the six months ended June 30, 2014.

The following table summarizes the stock option activity under the Plans:

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company records certain financial assets and liabilities at fair value in accordance with the provisions of ASC Topic 820 on fair value measurements. As defined in the guidance, fair value, defined as an exit price, represents the amount that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, the guidance defines a three-tier value hierarchy that prioritizes the inputs used in the valuation methodologies in measuring fair value.

• Level 1—Unadjusted quoted prices in active, accessible markets for identical assets or liabilities.

• Level 2—Other inputs that are directly or indirectly observable in the marketplace.

• Level 3—Unobservable inputs that are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following tables summarize the fair value of financial assets and liabilities that are measured at fair value and the classification by level of input within the fair value hierarchy:

As of June 30, 2015 and December 31, 2014, the estimated fair value of Aerie’s 2014 Convertible Notes was $111.1 million and $163.8 million, respectively. The estimated fair value of the 2014 Convertible Notes was determined using a scenario analysis and Monte Carlo simulation model to capture the various features of the 2014 Convertible Notes. The scenario analysis and Monte Carlo simulation require the use of Level 3 unobservable inputs and subjective assumptions, including but not limited to the probability of conversion, stock price volatility, the risk free interest rate and credit spread. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on June 30, 2015 as compared to December 31, 2014. The estimates presented are not necessarily indicative of amounts that could be realized in a current market exchange. The use of alternative market assumptions and estimation methodologies could have a material effect on these estimates of fair value.
