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 request, 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 in the U.S., Canada, Europe, Japan and elsewhere;

• our expectations related to the use of proceeds from our financing activities;

• our estimates regarding anticipated operating expenses and 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, manufacturing and supply management capabilities and strategy;

• third-party payor coverage and 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 ophthalmic products or product candidates; and

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

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics, industry change and other factors beyond our control, 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, 2016, as filed with the Securities and Exchange Commission (“SEC”) on March 9, 2017, and other documents we have filed or furnished with the SEC. You should not rely upon forward-looking statements as predictions of future events.

ii

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 development 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.

Any forward-looking statements that we make in this report speak only 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 Distribution, Inc., Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Distribution,” “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 small molecule products to treat patients with glaucoma and other diseases of the eye.

In 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited and Aerie Ireland Limited. Aerie assigned the beneficial rights to its non-U.S. and non-Canadian intellectual property for its lead product candidates 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 and Aerie Limited and Aerie Ireland Limited entered into a license arrangement pursuant to which Aerie Ireland Limited will develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment.

In 2016, Aerie assigned the beneficial rights to certain of Aerie’s intellectual property in the U.S. and Canada to Aerie Distribution, and amended and restated the research and development cost sharing agreement to transfer Aerie’s rights and obligations under the agreement to Aerie Distribution.

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 have 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 current 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 (Note 7).

If the Company does not successfully commercialize any of its current 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 may be forced to delay, reduce or eliminate its research and development programs or commercialization efforts.

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 consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K. The results for the three months endedMarch 31, 2017 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.

4

Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from the Company’s 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 Comprehensive loss on the consolidated statements of operations and comprehensive loss and in Accumulated other comprehensive loss on the consolidated balance sheets. For the three months endedMarch 31, 2017 and 2016, the Company recorded unrealized losses of $37,000 and unrealized gains of $111,000, respectively.

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 months endedMarch 31, 2017 or 2016.

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 March 31, 2017, 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.

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 and other current assets, approximate their respective carrying values due to the short-term nature of these instruments. The estimated fair value of the 2014 Convertible Notes (as defined in Note 7) was $255.4 million and $209.6 million as of March 31, 2017 and December 31, 2016, respectively. The increase 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 March 31, 2017 as compared to December 31, 2016. As of March 31, 2017 and December 31, 2016, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-03, which amends the FASB’s Accounting Standard Codification for SEC Staff announcements made at recent Emerging Issues Task Force (EITF) meetings. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, additional qualitative disclosures should be considered. The Company adopted this accounting standard update as of March 31, 2017. The adoption of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09, which provides guidance related to how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted this accounting standard update as of March 31, 2017. The provisions of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

5

In October 2016, the FASB issued ASU 2016-16, which eliminates the exception to the principle in ASC 740, Income Taxes,that generally requires comprehensive recognition of current and deferred income taxesfor all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. The new standard is effective for the Company for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted, and must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the loss is probable of occurring. Under this new standard, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The new standard is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and for those leases that have lease terms of more than 12 months. The guidance is effective for annual periods beginning after December 15, 2018, and all annual and interim periods thereafter, with early adoption permitted, and must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In January 2016, the FASB issued ASU 2016-01, which provides guidance related to the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual periods beginning after December 15, 2017, and all annual and interim periods thereafter, with early adoption permitted. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

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 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, Aerie’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

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

(1) Conversion is limited to a 9.985% ownership cap in shares of common stock by the holder. 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.

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 March 31, 2017 and December 31, 2016, the estimated fair value of the 2014 Convertible Notes was $255.4 million and $209.6 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 increase 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 March 31, 2017 as compared to December 31, 2016. 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.

6. Accounts Payable & Other Current Liabilities

7. Convertible Notes

On September 30, 2014, Aerie issued $125.0 million aggregate principle amount of senior secured convertible notes (“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. 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. (together with the other Deerfield entities listed above, “Deerfield”). The 2014 Convertible Notes were issued pursuant to a note purchase agreement (as amended and supplemented from time to time, the “Note Purchase Agreement”), dated as of September 8, 2014, among Aerie and the Deerfield entities party thereto.

9

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 are guaranteed on a senior secured basis by Aerie Distribution. The 2014 Convertible Notes constitute the senior secured obligations of Aerie and Aerie Distribution, collateralized by a first priority security interest in substantially all of the assets of Aerie and Aerie Distribution. The Note Purchase Agreement provides that, upon the request of Aerie, Deerfield will release all of the liens on the collateral and the security agreement will terminate 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.

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 shares of common stock or receive 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 current 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 Note Purchase Agreement 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 and its subsidiaries’ assets. As of March 31, 2017, Aerie was in compliance with the covenants. The Note Purchase Agreement also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s or Aerie Distribution’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s or Aerie Distribution’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie and its subsidiaries; 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.

10

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.

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

Unamortized debt discounts were $1.4 million as of March 31, 2017. 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 March 31, 2017:

(in thousands)	MARCH 31, 2017
Gross proceeds	$	125,000
Initial value of issuance costs recorded as debt discount	(2,146		)
Amortization of debt discount and issuance costs	761
Carrying value	$	123,615

For the three months endedMarch 31, 2017 and 2016 interest expense related to the 2014 Convertible Notes was $521,000 and $545,000, respectively.

8. Build-to-Suit Lease

In January 2017, the Company entered into a lease agreement, expiring in September 2037, for a new manufacturing plant in Athlone, Ireland under which the Company is leasing approximately 30,000 square feet of interior floor space for build-out. The Company is permitted to terminate the lease beginning in September 2027. Total expected rental payments through September 2027 are approximately $2.5 million. Total expected rental payments through the expiration of the lease are approximately $5.7 million.

The Company is not the legal owner of the leased space. However, in accordance with ASC 840, Leases, the Company is deemed to be the owner of the leased space, including the building shell, during the construction period because of the Company’s expected level of direct financial and operational involvement in the substantial tenant improvements required. As a result, the Company capitalized approximately $4.2 million as a build-to-suit asset within property, plant and equipment, net and recognized a corresponding build-to-suit facility lease obligation within other non-current liabilities on its consolidated balance sheets equal to the estimated replacement cost of the building at the inception of the lease.

Additionally, construction costs incurred as part of the build-out and tenant improvements will also be capitalized within property, plant and equipment, net. Rental payments made under the lease will be allocated to interest expense and the build-to-suit facility lease obligation, based on the implicit rate of the build-to-suit facility lease obligation. The build-to-suit facility lease obligation was approximately $4.2 million as of March 31, 2017.

9. Stock Purchase Warrants

As of March 31, 2017, the following equity classified warrants were outstanding:

NUMBER OF UNDERLYING SHARES	EXERCISE PRICE PER SHARE		WARRANT EXPIRATION DATE	TYPE OF EQUITY SECURITY
75,000	$	5.00	February 2019	Common Stock
75,000	$	5.00	November 2019	Common Stock
7,500	$	5.00	August 2020	Common Stock
223,482	$	0.05	December 2019	Common Stock

The warrants outstanding as of March 31, 2017 are all currently exercisable with weighted-average remaining lives of 2.5 years.

10. Stock-based Compensation

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

	THREE MONTHS ENDED   MARCH 31,
(in thousands)	2017		2016
Research and development	$	1,064	$	712
Selling, general and administrative	3,786		2,822
Total	$	4,850	$	3,534

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 the required service is performed. The fair value of RSAs granted is based on the market value of Aerie’s common stock on the date of grant. Compensation expense related to time-based RSAs is expensed on a straight-line basis over the vesting period. For RSAs with non-market performance conditions, the Company evaluates the criteria for each grant to determine the probability that the performance condition will be achieved. Compensation expense for RSAs with non-market performance conditions is recognized over the respective service period when it is deemed probable that the performance condition will be satisfied.

As of March 31, 2017, the Company had $43.4 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 3.0 years as of March 31, 2017. The weighted average remaining contractual life on all outstanding options as of March 31, 2017 was 7.5 years.

As of March 31, 2017, the Company had $11.9 million of unrecognized compensation expense, related to unvested RSAs. This cost is expected to be recognized over the weighted average contractual term period of 3.4 years as of March 31, 2017.

Equity Plans

The Company maintains three equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”), 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”), as described below, and the Aerie Pharmaceuticals, Inc. Inducement Award Plan (the “Inducement Award Plan”), as described below. The 2005 Plan, the Amended and Restated Equity Plan and the Inducement Award 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 have been or will be made under the 2005 Plan. Any remaining shares available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan.

12

At the 2015 Annual Meeting of Stockholders held on April 10, 2015, Aerie’s stockholders approved the adoption of the Amended and Restated Equity Plan and no additional awards have been or will be made under the 2013 Equity Plan. Any remaining shares 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 Aerie, including equity awards that were available for issuance under the 2013 Equity Plan.

On December 7, 2016, Aerie’s Board of Directors approved the Inducement Award Plan which provides for the granting of up to 418,000 equity awards in respect of common stock of Aerie, which was increased by 250,000 shares on March 30, 2017. Awards granted under the Inducement Award Plan are intended to qualify as employment inducement awards under NASDAQ Listing Rule 5635(c)(4).

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

	NUMBER OF SHARES		WEIGHTED AVERAGE EXERCISE PRICE		WEIGHTED AVERAGE REMAINING CONTRACTUAL LIFE (YEARS)	AGGREGATE INTRINSIC VALUE (000’s)

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, 2016, as filed with the SEC on March 9, 2017. 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, 2016 and other documents we have filed or furnished with the SEC 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 two advanced stage product candidates are designed to lower intraocular pressure, or IOP, in patients with open-angle glaucoma or ocular hypertension. Both product candidates are small molecule eye drops dosed once-daily and have shown in preclinical and clinical trials to be effective in lowering IOP, with novel mechanisms of action, or MOAs, and a positive safety profile.

Our first product candidate is once-daily Rhopressa™ (netarsudil ophthalmic solution) 0.02% (“Rhopressa^TM”). We resubmitted our new drug application (“NDA”) with the U.S. Food and Drug Administration (“FDA”) for Rhopressa™ on February 28, 2017 and expect a standard 12-month FDA review period for the NDA from the date of resubmission. Our initial submission, announced in September 2016, was withdrawn as a result of a contract manufacturer of our drug product not being prepared for pre-approval inspection by the FDA. The NDA submission included our second Phase 3 registration trial for Rhopressa^TM, named “Rocket 2,” as the pivotal clinical trial and our initial Phase 3 registration trial, named “Rocket 1,” as supportive in nature. We successfully completed the 90-day efficacy component of Rocket 2 in September 2015 when the trial achieved its primary efficacy endpoint of demonstrating non-inferiority of Rhopressa™ compared to timolol. The final primary baseline IOP ranges for Rocket 2 were above 20 millimeters of mercury (“mmHg”) to below 25 mmHg. We also included as supportive data the 90-day efficacy results of Rocket 4 and Mercury 1, each as further discussed below, with the NDA submission for Rhopressa^TM.

In Rocket 2, in addition to successfully achieving non-inferiority to timolol at the primary efficacy endpoint range, the 12-month safety data from this registration trial also confirmed a positive safety profile for the drug and demonstrated a consistent IOP lowering effect throughout the 12-month period at the specified 8 a.m. measurement time points. In the 90-day efficacy results from Mercury 1, Rhopressa™ demonstrated non-inferiority to latanoprost, the most commonly prescribed drug for the treatment of patients with glaucoma, at baseline IOPs from above 20 mmHg to below 25 mmHg.

We recently completed our fourth Phase 3 registration trial for Rhopressa™, named “Rocket 4,” in the U.S., which was designed to generate adequate six-month safety data for European regulatory approval, which we expect to file for in the second half of 2018. The six-month safety data were consistent with observations in previous Rhopressa™ three-month and 12-month Phase 3 registration trials. Additionally, the diurnal efficacy measurements at months four, five and six remained within the non-inferiority range compared to timolol at baseline IOPs ranging from above 20 mmHg to below 25 mmHg, and also from above 20 mmHg to below 27 mmHg. In October 2016, we announced the 90-day efficacy results from Rocket 4 where Rhopressa™ achieved its primary efficacy endpoint of demonstrating non-inferiority of Rhopressa™ compared to timolol for patients with baseline IOPs ranging from above 20 mmHg to below 25 mmHg, and final 90-day efficacy results also demonstrated non-inferiority of Rhopressa^TM to timolol at the range of above 20 mmHg to below 30 mmHg. A third Phase 3 registration trial for Rhopressa^TM, named “Rocket 3,” was a small 12-month safety-only study in Canada that was not necessary for the NDA submission and for which we have discontinued enrollment.

The Rhopressa^TM Phase 3 registration trial results have shown no drug-related serious adverse events or drug related systemic adverse events, with the most common adverse event reported being conjunctival hyperemia, or eye redness, with incidence rates of approximately 50% across all Phase 3 registration trials for Rhopressa^TM, the majority of which was reported as mild.

In a 24-hour, 12-patient pilot study comparing Rhopressa^TM efficacy to that of placebo, Rhopressa™ demonstrated similar levels of IOP lowering during nocturnal and diurnal periods. This is potentially a further differentiating feature of Rhopressa™ when considering that currently marketed products have demonstrated little or no efficacy at night and eye pressure is typically highest when patients are asleep.

14

We are developing Rhopressa™ as the first of a new class of compounds that is designed to lower IOP in patients through novel MOAs. We believe that, if approved, Rhopressa™ will represent the first new MOAs for lowering IOP in patients with glaucoma in over 20 years. Based on preclinical studies and clinical data to date, we expect that Rhopressa™, if approved, will have the potential to compete with non-PGA (prostaglandin analogue) products as a preferred adjunctive therapy to PGAs, due to its targeting of the diseased tissue known as the trabecular meshwork, or TM, its demonstrated IOP-lowering ability at consistent levels across tested baselines with once-daily dosing, its potential synergistic effect with PGA products, and its lack of serious drug related adverse events. In addition, if approved, we believe that Rhopressa™ may also potentially become a preferred therapy where PGAs are contraindicated, for patients who do not respond to PGAs and for patients who choose to avoid the cosmetic issues associated with PGA products.

Our second product candidate, once-daily Roclatan™ (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% (“Roclatan™”), is a fixed-dose combination of Rhopressa™ and latanoprost. We currently have two Phase 3 registration trials for Roclatan™ in process. The first Phase 3 registration trial for Roclatan™, named “Mercury 1,” which is a 12-month safety trial with a 90-day efficacy readout, commenced in September 2015, and in September 2016 we announced that Mercury 1 achieved its primary efficacy endpoint of demonstrating superiority of Roclatan™ to each of its components.

The Mercury 1 trial evaluated patients with maximum baseline IOPs ranging from above 20 mmHg to below 36 mmHg at nine measured time points over the 90-day efficacy period. In the 90-day efficacy results, the IOP-lowering effect of Roclatan^TM exceeded that of the latanoprost monotherapy in a range of 1.3 mmHg to 2.5 mmHg and that of the Rhopressa^TM monotherapy in a range of 1.8 mmHg to 3.0 mmHg.  Roclatan^TM reduced mean diurnal IOPs to 16 mmHg or lower in 61% of patients, a significantly higher percentage than observed in the comparator arms in the study.

The safety and tolerability results for Roclatan™ from the90-day efficacy period of Mercury 1 showed no drug-related serious adverse events or drug related systemic adverse events. The most common adverse event observed in the Roclatan^TM arm was conjunctival hyperemia, or eye redness, which was reported in approximately 50% of patients, approximately 80% of which was reported as mild. There were no drug-related serious adverse events for any of the comparators in the trial. We expect to report Mercury 1 topline 12-month safety data in the third quarter of 2017.

The second Phase 3 registration trial for Roclatan™, named “Mercury 2,” commenced in March 2016. Mercury 2 is a 90-day efficacy and safety trial designed to demonstrate superiority of Roclatan™ to each of its components. The Mercury 2 trial design is identical to that of Mercury 1, except that Mercury 2 is a 90-day trial without the additional nine-month safety extension included in Mercury 1. We expect to report the topline 90-day efficacy data for Mercury 2 in the second quarter of 2017. If both Mercury 1 and Mercury 2 are successful, we expect to submit an NDA for Roclatan™ in late 2017 or early 2018, which may be prior to obtaining approval for Rhopressa^TM. We are permitted to submit the Roclatan™ NDA while the Rhopressa^TM NDA is still being reviewed by the FDA.

Mercury 1 and Mercury 2 will also be used for European approval of Roclatan™, and we plan to initiate a third Phase 3 registration trial for Roclatan™, named “Mercury 3,” in Europe in mid-2017. Mercury 3 will be designed to compare Roclatan™ to Ganfort^®, a fixed dose combination product of bimatoprost and timolol marketed in Europe, which if successful, is expected to improve our commercialization prospects in that region.

We believe, based on our preclinical studies and clinical trials to date, that Roclatan™, if approved, will be the only glaucoma product that covers the full spectrum of currently known IOP-lowering MOAs, giving it the potential to provide a greater IOP-lowering effect than any currently marketed glaucoma product. Therefore, we believe that Roclatan^TM, if approved, could compete with both PGA and non-PGA therapies for patients requiring maximal IOP lowering, including those with higher IOPs and those who present with significant disease progression despite currently available therapies.

In addition to our continued use of product sourced from our current contract manufacturer based in the U.S., in January 2017, we announced that we are building out a new manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, expected to produce commercial supplies of our current product candidates, Rhopressa^TM and Roclatan^TM. If we obtain regulatory approval, commercial product supply of Rhopressa^TM from the plant is expected to be available by 2020. We are also in the process of adding a second contract manufacturer.

Our stated objective is to build a major ophthalmic pharmaceutical company. In addition to our primary product candidates, Rhopressa™ and Roclatan™, we continue to explore the impact of Rhopressa™ on the diseased TM. We have issued several research updates on preclinical results demonstrating that Rhopressa™ may have the potential for disease modification, including stopping and potentially reversing fibrosis in the TM, and also increasing perfusion in the trabecular outflow pathway thus increasing both drainage and the delivery of nutrients to the diseased tissue. We are also conducting ongoing

15

research to evaluate injectable sustained release formulation technologies with the potential capability of delivering Rhopressa™ internally in the eye over several months for the treatment of glaucoma.

We are also evaluating possible uses of our existing proprietary portfolio of Rho kinase inhibitors beyond glaucoma. Our owned preclinical small molecule, AR-13154, has demonstrated the potential for the treatment of wet age-related macular degeneration (AMD) by inhibiting Rho kinase and Protein kinase C and has shown lesion size decreases in an in vivo preclinical model of wet AMD at levels similar to the current market-leading wet AMD anti-VEGF product, and even greater lesion size reduction in combination with the current market-leading wet AMD anti-VEGF product. Further, in our preclinical studies, we have seen a promising potential of this molecule to reduce neovascularization in a model of proliferative diabetic retinopathy. Pending additional studies, AR-13154 may have the potential to provide an entirely new mechanism and pathway to treat this disease.

We may enter into research collaboration arrangements, license, acquire or develop additional product candidates and technologies to broaden our presence in ophthalmology, and we continually explore and discuss potential additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners. Our approach has consistently been to explore opportunities with minimal initial investment allowing us to more fully evaluate the probability of success prior to making a material commitment. We are currently focused on the evaluation of technologies for the delivery of our owned molecules to the front and back of the eye over sustained periods.

Our strategy includes developing our business outside of North America, including obtaining regulatory approval in Europe and Japan on our own for our current product candidates. For commercialization outside of North America, we expect to explore partnership opportunities through collaboration and licensing arrangements in Europe and Japan.

In 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 (“Aerie Limited”), and Aerie Pharmaceuticals Ireland Limited, a wholly-owned subsidiary (“Aerie Ireland Limited”). We assigned the beneficial rights to our non-U.S. and non-Canadian intellectual property for our lead product candidates to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, we and Aerie Limited entered into a research and development cost sharing agreement pursuant to which we and Aerie Limited will share the costs of the development of intellectual property and Aerie Limited and Aerie Ireland Limited entered into a license arrangement pursuant to which Aerie Ireland Limited will develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment. In 2016, we assigned the beneficial rights to certain of our intellectual property in the U.S. and Canada to Aerie Distribution, Inc., a wholly owned subsidiary (“Aerie Distribution”), and amended and restated the research and development cost sharing agreement to transfer our rights and obligations under the agreement to Aerie Distribution.

We have incurred net losses since our inception in June 2005. Our operations to date have primarily been limited to research and development and raising capital. As of March 31, 2017, we had an accumulated deficit of $342.4 million. We recorded net losses of $25.8 million and $22.7 million for the three months endedMarch 31, 2017 and 2016, 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 and manufacturing of our product candidates.

We expect to continue to incur significant operating losses until such a time when our product candidates are commercially successful, if at all. In 2017, we expect our selling, general and administrative expenses to increase as we prepare for potential commercialization of our product candidates, including increases in personnel costs and increases in expenses and costs related to expanded infrastructure, pre-launch commercial operations and manufacturing activities. Additionally, we anticipate that our clinical expenses will decline in 2017 as we complete clinical trials and pursue regulatory approval for our product candidates in the U.S.

Our cash, cash equivalents and investments totaled $207.9 million as of March 31, 2017 and are currently expected to provide sufficient resources for our ongoing needs. See “—Operating Capital Requirements.”

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 current product candidates. If we do not successfully commercialize any of our current product candidates, we may be unable to generate product revenue or achieve profitability.

16

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 or manufacturing 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 product candidates.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries, benefits and stock-based compensation for all officers and employees in general management, sales and marketing, finance, and administration. Other significant expenses include commercial related manufacturing costs, including building commercial inventory in preparation for the potential launch of Rhopressa^TM, pre-launch sales and marketing activities, facilities expenses and professional fees for audit, tax, legal and other services.

We expect that our selling, general and administrative expenses will increase with the continued advancement of our product candidates and as we prepare for potential commercialization. We expect these increases will likely be associated with the hiring of additional personnel, increased levels of legal, compliance and accounting expenses, and preparatory commercial operations and manufacturing activity.

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 research and development 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 and FDA related fees, are classified as direct clinical. Direct costs associated with our former collaboration arrangements and pipeline activities, including our ongoing preclinical activities, are included in Other research and development activities. Internal personnel costs associated with these activities are classified as “unallocated.” 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.”

17

The following table shows our research and development expenses by product candidate and type of activity for the three months endedMarch 31, 2017 and 2016:

	THREE MONTHS ENDED   MARCH 31,
	2017		2016
	(unaudited) (in thousands)
RhopressaTM
Direct non-clinical	$	255	$	655
Direct clinical	895		3,383
Total	$	1,150	$	4,038
RoclatanTM
Direct non-clinical	$	574	$	501
Direct clinical	2,837		3,001
Total	$	3,411	$	3,502
Other research and development activities	$	121	$	521
Unallocated	$	6,272	$	4,248
Total research and development expense	$	10,954	$	12,309

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.

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 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 any products that we may develop. 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 any product candidate 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, market acceptance and commercial viability.

18

Other Income (Expense), Net

Other income primarily consists of interest earned on our cash and cash equivalents and investments. 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 and accretion of debt discounts and premiums 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 operating expense accruals. 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 consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Results of Operations

Comparison of the Three Months Ended March 31, 2017 and 2016

The following table summarizes the results of our operations for the three months ended March 31, 2017 and 2016:

	THREE MONTHS ENDED   MARCH 31,						INCREASE			% INCREASE

Net loss before income taxes	$	(25,741	)	$	(22,658	)

Selling, general and administrative expenses

Selling, general and administrative expenses increased by $4.7 million for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016. This increase was primarily associated with the expansion of our employee base and preparatory commercial operations and manufacturing activities. 

Personnel costs increased by $1.8 million, including an increase in employee stock based compensation expense of $1.0 million and an increase in salaries and related expenses of $0.8 million. Additionally, outside professional fees and facility expenses increased by $0.3 million and $0.1 million, respectively, to support the growth in our operations. 

Our direct preparatory commercial operations and manufacturing activities were approximately $2.7 million for the three months ended March 31, 2017 and included scale-up of our current manufacturing activities and building commercial inventory in preparation for the potential launch of Rhopressa^TM. This represented an increase of $1.6 million for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016. Additionally, pre-launch sales and marketing planning increased by $0.7 million for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016.

19

Research and development expenses

Research and development expenses decreased by $1.4 million for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016. During the three months ended March 31, 2017, our research and development activity was primarily associated with Phase 3 registration trials for Rhopressa™ and Roclatan™. We resubmitted our NDA for Rhopressa™ in February 2017. As such, costs for Rhopressa™ decreased by $2.9 million as direct clinical costs decreased by $2.5 million and direct non-clinical costs decreased by $0.4 million due to the timing of our clinical trials. Costs for Roclatan™ decreased by $0.1 million as direct clinical costs decreased by $0.2 million and direct non-clinical costs increased by $0.1 million associated with the commencement of Mercury 1 and Mercury 2 in September 2015 and March 2016, respectively, and preparatory activities for Mercury 3 which is anticipated to commence in mid-2017. Unallocated expenses increased by $2.0 million as personnel costs, consulting expenses and travel increased by $1.1 million, $0.4 million and $0.2 million, respectively.

Liquidity and Capital Resources

Since our inception, we have funded operations primarily through the sale of equity securities 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 until such a time when our product candidates are commercially successful, if at all.

Prior to our IPO, we raised net cash proceeds of $78.6 million from the private placement of convertible preferred stock and convertible notes. Prior to and in connection with our IPO, all outstanding shares of convertible preferred stock and all convertible notes were converted into shares of common stock. On October 30, 2013, we completed our IPO and raised net proceeds of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million.

Since our IPO, we have issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”), for which we received net proceeds of approximately $122.9 million, after deducting discounts and certain expenses of $2.1 million, have issued 5,933,712 shares of our common stock under our former “at-the-market” sales agreements, for which we received net proceeds of approximately $146.6 million, after deducting commissions at a rate of up to 3% of the gross sales price per share sold and other fees and expenses, and have issued 2,542,373 shares of our common stock pursuant an underwriting agreement, dated September 15, 2016, with Cantor Fitzgerald & Co., for which we received net proceeds of approximately $71.0 million, after deducting the underwriting discount, fees and expenses of approximately $4.0 million.

As of March 31, 2017, our principal sources of liquidity were our cash, cash equivalents and investments, which totaled approximately $207.9 million. We believe that our cash and cash equivalents and investments as of March 31, 2017 will provide sufficient resources for our ongoing needs. See “—Operating Capital Requirements.”

The following table summarizes our sources and uses of cash:

	THREE MONTHS ENDED   MARCH 31,
	2017			2016
	(unaudited) (in thousands)
Net cash (used in) provided by:
Operating activities	$	(24,854	)	$	(19,358	)
Investing activities	(33,605		)	2,436
Financing activities	48			128
Net change in cash and cash equivalents	$	(58,411	)	$	(16,794	)

During the three months ended March 31, 2017 and 2016, our operating activities used net cash of $24.9 million and $19.4 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 three months ended March 31, 2017 as compared to the three months endedMarch 31, 2016 was primarily due to increased selling, general and administrative expenses associated with the expansion of our employee base and preparatory commercial operations and manufacturing activities as previously described, see “—Results of Operations.” Additionally, in connection with the initial NDA submission for Rhopressa^TM, announced in September 2016, we paid the FDA a user fee of $2.4 million, of which $1.8 million was reimbursed to us during the three

20

months ended March 31, 2017. The $0.6 million retention by the FDA results from our withdrawal of the initial NDA submission prior to FDA acceptance of the NDA for review.

During the three months ended March 31, 2017, our investing activities used net cash of $33.6 million primarily related to purchases of available-for-sale investments of $45.6 million and purchases of fixed assets of $0.9 million primarily associated with equipment related to our manufacturing activities. These purchases were partially offset by maturities of available-for-sale investments of $12.9 million During the three months endedMarch 31, 2016, our investing activities provided net cash of approximately $2.4 million primarily related to maturities of available-for-sale investments of $16.0 million, which were partially offset by purchases of available-for-sale investments of $13.3 million.

During the three months ended March 31, 2017 and 2016, our financing activities provided net cash of $48,000 and $0.1 million, respectively. The net cash provided by financing activities for the three months ended March 31, 2017 was primarily related to proceeds of $0.7 million from exercises of stock options and stock purchase rights under our employee stock purchase plan, which were offset by the repurchase of shares of restricted stock to settle statutory employee tax withholding obligations of $0.7 million. The net cash provided by financing activities for the three months endedMarch 31, 2016 was primarily related to proceeds of $0.3 million from exercises of stock purchase rights under our employee stock purchase plan, which were partially offset by the repurchase of shares of restricted stock to settle statutory employee tax withholding obligations of $0.1 million.

Operating Capital Requirements

We expect to incur on-going operating losses as we continue to conduct and complete Phase 3 clinical trial activity primarily for Roclatan^TM, and further prepare in 2017 for the potential commercialization in the U.S. of Rhopressa^TM as early as 2018. Clinical trial expenses for trials conducted in the U.S. are expected to decrease in 2017 and we expect to incur additional clinical and other expenses abroad as we execute our strategy for future commercialization in Europe and Japan. Additionally, in January 2017, we entered into a lease agreement for a new manufacturing plant in Ireland under which we are leasing approximately 30,000 square feet of interior floor space for build-out. Estimated project-wide construction and equipment costs are expected to total approximately $25.0 million (excluding ongoing labor-related and lease expenses), of which approximately $16.0 million is expected to be spent in 2017.

We currently expect that our existing cash and cash equivalents and investments will provide sufficient resources for our ongoing needs to complete all currently known non-clinical and clinical requirements for our development programs and advancing Rhopressa^TM and Roclatan^TM to approval and product commercialization in the U.S., pending successful outcome of the remaining trials. We also intend to use these funds for general corporate purposes and for strategic growth opportunities, including the execution of clinical trials in Japan, the construction of our manufacturing plant in Ireland as described above and the continuation of preclinical activity in support of our product pipeline. In the future, we may decide based on ongoing forecast updates, new strategic initiatives, market conditions, or for other reasons that additional financings are desirable or needed.

We also expect to continue to incur increasing costs associated with the growth of our operations, including but not limited to, increased costs and expenses for personnel associated with the expected commercialization of our product candidates, costs associated with our new manufacturing plant in Ireland and other third-party expenses and fees.

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 ongoing and future preclinical studies and clinical trials for our product candidates;

• costs of any follow-on development or products, including the exploration and/or development of any additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas;

• costs of any new business strategies;

• costs to build-out our new manufacturing plant in Ireland;

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

• outcome, timing and costs of seeking regulatory approval;

21

• 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 acquisitions, collaborations, licensing, consulting or other arrangements; 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, funding our internal manufacturing capabilities, funding the ongoing development of any additional product candidates and technologies that we might license, acquire or develop internally or through research and collaboration arrangements. 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 and manufacturing efforts.

Outstanding Indebtedness

As of March 31, 2017, our total indebtedness consisted of our $125.0 million aggregate principal amount of 2014 Convertible Notes. For a discussion of the 2014 Convertible Notes, see Note 7 to our unaudited consolidated financial statements appearing elsewhere in this report.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations at March 31, 2017:

	TOTAL		LESS THAN 1 YEAR		1 TO 3 YEARS		3 TO 5 YEARS		MORE THAN 5 YEARS
(in thousands)
Lease obligations(1)	$	9,069	$	1,601	$	3,407	$	2,603	$	1,458
2014 Convertible Notes(2)	125,000		—		—		125,000		—
	$	134,069	$	1,601	$	3,407	$	127,603	$	1,458

(1) Our lease obligations are primarily related to our principal executive office in Irvine, California, corporate offices in Bedminster, New Jersey and Dublin, Ireland and our research facility in Durham, North Carolina. Additionally, in January 2017, we entered into a lease agreement for a new manufacturing plant in Athlone, Ireland under which we are leasing approximately 30,000 square feet of interior floor space for build-out. We are permitted to terminate the lease agreement beginning in September 2027.

(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 7 to our unaudited consolidated financial statements appearing elsewhere in this report for further information.

In April 2017, we entered into a lease agreement to expand our principal executive office in Irvine, California. Total additional rental payments through January 2022 are approximately $1.7 million and are excluded from the table above.

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

22

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.

We may take advantage of these exemptions until we are no longer an “emerging growth company.” We would cease to be an “emerging growth company” upon the earliest of: (i) December 31, 2018; (ii) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more; (iii) the date on which we have, during the previous three-year period, issued more than $1 billion in non-convertible debt securities; or (iv) as of the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million as of the end of the second quarter of that fiscal year.

If the market value of our common stock held by non-affiliates continues to exceed $700 million as of June 30, 2017, then as of the year ending December 31, 2017, we would cease to be an “emerging growth company.” If we cease to be an “emerging growth company,” beginning with our annual report on Form 10-K for the year ending December 31, 2017, we will be subject to Section 404(b) of the Sarbanes-Oxley Act, which requires that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting.

Recent Accounting Pronouncements

For a discussion of recently issued accounting standards, see Note 2 to our unaudited consolidated financial statements included elsewhere in this report.

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 March 31, 2017, totaled $139.5 million and consisted of cash, money market funds and commercial paper with original maturities of three months or less from the date of purchase. Our investments totaled $68.3 million as of March 31, 2017 and consisted of certificates of deposit, commercial paper and corporate bonds. We had cash, cash equivalents and investments of $233.7 million as of December 31, 2016. Given the short-term nature of our cash, 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 material foreign currency or any other derivative financial instruments.

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 March 31, 2017, 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.

23

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.

24

PART II. OTHER INFORMATION

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The Company

The Company

Aerie Pharmaceuticals, Inc. (“Aerie”), with its wholly-owned subsidiaries Aerie Distribution, Inc., Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Distribution,” “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 small molecule products to treat patients with glaucoma and other diseases of the eye.

In 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited and Aerie Ireland Limited. Aerie assigned the beneficial rights to its non-U.S. and non-Canadian intellectual property for its lead product candidates 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 and Aerie Limited and Aerie Ireland Limited entered into a license arrangement pursuant to which Aerie Ireland Limited will develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment.

In 2016, Aerie assigned the beneficial rights to certain of Aerie’s intellectual property in the U.S. and Canada to Aerie Distribution, and amended and restated the research and development cost sharing agreement to transfer Aerie’s rights and obligations under the agreement to Aerie Distribution.

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 have 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 current 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 (Note 7).

If the Company does not successfully commercialize any of its current 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 may be forced to delay, reduce or eliminate its research and development programs or commercialization efforts.

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 consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K. The results for the three months endedMarch 31, 2017 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 the Company’s 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 Comprehensive loss on the consolidated statements of operations and comprehensive loss and in Accumulated other comprehensive loss on the consolidated balance sheets. For the three months endedMarch 31, 2017 and 2016, the Company recorded unrealized losses of $37,000 and unrealized gains of $111,000, respectively.

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 months endedMarch 31, 2017 or 2016.

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 March 31, 2017, 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.

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 and other current assets, approximate their respective carrying values due to the short-term nature of these instruments. The estimated fair value of the 2014 Convertible Notes (as defined in Note 7) was $255.4 million and $209.6 million as of March 31, 2017 and December 31, 2016, respectively. The increase 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 March 31, 2017 as compared to December 31, 2016. As of March 31, 2017 and December 31, 2016, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-03, which amends the FASB’s Accounting Standard Codification for SEC Staff announcements made at recent Emerging Issues Task Force (EITF) meetings. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, additional qualitative disclosures should be considered. The Company adopted this accounting standard update as of March 31, 2017. The adoption of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09, which provides guidance related to how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted this accounting standard update as of March 31, 2017. The provisions of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

In October 2016, the FASB issued ASU 2016-16, which eliminates the exception to the principle in ASC 740, Income Taxes,that generally requires comprehensive recognition of current and deferred income taxesfor all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. The new standard is effective for the Company for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted, and must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the loss is probable of occurring. Under this new standard, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The new standard is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and for those leases that have lease terms of more than 12 months. The guidance is effective for annual periods beginning after December 15, 2018, and all annual and interim periods thereafter, with early adoption permitted, and must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In January 2016, the FASB issued ASU 2016-01, which provides guidance related to the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual periods beginning after December 15, 2017, and all annual and interim periods thereafter, with early adoption permitted. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

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 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, Aerie’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.

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

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 March 31, 2017 and December 31, 2016, the estimated fair value of the 2014 Convertible Notes was $255.4 million and $209.6 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 increase 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 March 31, 2017 as compared to December 31, 2016. 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.

Debt Disclosure [Abstract]

Convertible Notes

Convertible Notes

On September 30, 2014, Aerie issued $125.0 million aggregate principle amount of senior secured convertible notes (“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. 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. (together with the other Deerfield entities listed above, “Deerfield”). The 2014 Convertible Notes were issued pursuant to a note purchase agreement (as amended and supplemented from time to time, the “Note Purchase Agreement”), dated as of September 8, 2014, among Aerie and the Deerfield entities party thereto.

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 are guaranteed on a senior secured basis by Aerie Distribution. The 2014 Convertible Notes constitute the senior secured obligations of Aerie and Aerie Distribution, collateralized by a first priority security interest in substantially all of the assets of Aerie and Aerie Distribution. The Note Purchase Agreement provides that, upon the request of Aerie, Deerfield will release all of the liens on the collateral and the security agreement will terminate 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.

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 shares of common stock or receive 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 current 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 Note Purchase Agreement 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 and its subsidiaries’ assets. As of March 31, 2017, Aerie was in compliance with the covenants. The Note Purchase Agreement also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s or Aerie Distribution’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s or Aerie Distribution’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie and its subsidiaries; 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.

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

Unamortized debt discounts were $1.4 million as of March 31, 2017. 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 March 31, 2017:

(in thousands)	MARCH 31, 2017
Gross proceeds	$	125,000

For the three months endedMarch 31, 2017 and 2016 interest expense related to the 2014 Convertible Notes was $521,000 and $545,000, respectively.

Leases [Abstract]

Built-to-Suit Lease

Build-to-Suit Lease

In January 2017, the Company entered into a lease agreement, expiring in September 2037, for a new manufacturing plant in Athlone, Ireland under which the Company is leasing approximately 30,000 square feet of interior floor space for build-out. The Company is permitted to terminate the lease beginning in September 2027. Total expected rental payments through September 2027 are approximately $2.5 million. Total expected rental payments through the expiration of the lease are approximately $5.7 million.

The Company is not the legal owner of the leased space. However, in accordance with ASC 840, Leases, the Company is deemed to be the owner of the leased space, including the building shell, during the construction period because of the Company’s expected level of direct financial and operational involvement in the substantial tenant improvements required. As a result, the Company capitalized approximately $4.2 million as a build-to-suit asset within property, plant and equipment, net and recognized a corresponding build-to-suit facility lease obligation within other non-current liabilities on its consolidated balance sheets equal to the estimated replacement cost of the building at the inception of the lease.

Additionally, construction costs incurred as part of the build-out and tenant improvements will also be capitalized within property, plant and equipment, net. Rental payments made under the lease will be allocated to interest expense and the build-to-suit facility lease obligation, based on the implicit rate of the build-to-suit facility lease obligation. The build-to-suit facility lease obligation was approximately $4.2 million as of March 31, 2017.

Stock-based Compensation

Stock-based Compensation

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

	THREE MONTHS ENDED   MARCH 31,
(in thousands)	2017		2016
Research and development	$	1,064	$	712
Selling, general and administrative	3,786		2,822
Total	$	4,850	$	3,534

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 the required service is performed. The fair value of RSAs granted is based on the market value of Aerie’s common stock on the date of grant. Compensation expense related to time-based RSAs is expensed on a straight-line basis over the vesting period. For RSAs with non-market performance conditions, the Company evaluates the criteria for each grant to determine the probability that the performance condition will be achieved. Compensation expense for RSAs with non-market performance conditions is recognized over the respective service period when it is deemed probable that the performance condition will be satisfied.

As of March 31, 2017, the Company had $43.4 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 3.0 years as of March 31, 2017. The weighted average remaining contractual life on all outstanding options as of March 31, 2017 was 7.5 years.

As of March 31, 2017, the Company had $11.9 million of unrecognized compensation expense, related to unvested RSAs. This cost is expected to be recognized over the weighted average contractual term period of 3.4 years as of March 31, 2017.

Equity Plans

The Company maintains three equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”), 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”), as described below, and the Aerie Pharmaceuticals, Inc. Inducement Award Plan (the “Inducement Award Plan”), as described below. The 2005 Plan, the Amended and Restated Equity Plan and the Inducement Award 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 have been or will be made under the 2005 Plan. Any remaining shares 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, Aerie’s stockholders approved the adoption of the Amended and Restated Equity Plan and no additional awards have been or will be made under the 2013 Equity Plan. Any remaining shares 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 Aerie, including equity awards that were available for issuance under the 2013 Equity Plan.

On December 7, 2016, Aerie’s Board of Directors approved the Inducement Award Plan which provides for the granting of up to 418,000 equity awards in respect of common stock of Aerie, which was increased by 250,000 shares on March 30, 2017. Awards granted under the Inducement Award Plan are intended to qualify as employment inducement awards under NASDAQ Listing Rule 5635(c)(4).

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

	NUMBER OF SHARES		WEIGHTED AVERAGE EXERCISE PRICE		WEIGHTED AVERAGE REMAINING CONTRACTUAL LIFE (YEARS)	AGGREGATE INTRINSIC VALUE (000’s)

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 consolidated financial statements and accompanying notes for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K. The results for the three months endedMarch 31, 2017 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 the Company’s 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 Comprehensive loss on the consolidated statements of operations and comprehensive loss and in Accumulated other comprehensive loss on the consolidated balance sheets. For the three months endedMarch 31, 2017 and 2016, the Company recorded unrealized losses of $37,000 and unrealized gains of $111,000, respectively.

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 months endedMarch 31, 2017 or 2016.

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.

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 and other current assets, approximate their respective carrying values due to the short-term nature of these instruments.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-03, which amends the FASB’s Accounting Standard Codification for SEC Staff announcements made at recent Emerging Issues Task Force (EITF) meetings. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, additional qualitative disclosures should be considered. The Company adopted this accounting standard update as of March 31, 2017. The adoption of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09, which provides guidance related to how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted this accounting standard update as of March 31, 2017. The provisions of this accounting standard update did not have a material effect on the Company’s consolidated financial statements and disclosures.

In October 2016, the FASB issued ASU 2016-16, which eliminates the exception to the principle in ASC 740, Income Taxes,that generally requires comprehensive recognition of current and deferred income taxesfor all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. The new standard is effective for the Company for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted, and must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the loss is probable of occurring. Under this new standard, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. The new standard is effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and for those leases that have lease terms of more than 12 months. The guidance is effective for annual periods beginning after December 15, 2018, and all annual and interim periods thereafter, with early adoption permitted, and must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

In January 2016, the FASB issued ASU 2016-01, which provides guidance related to the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual periods beginning after December 15, 2017, and all annual and interim periods thereafter, with early adoption permitted. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and disclosures.

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 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, Aerie’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.
