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,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “may,” “would,” “could,” “might,” “will,” “should” 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, including statements regarding the timing of initiation and completion of the studies and trials;

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

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

• our expectations related to the use of proceeds from our initial public offering (“IPO”) in October 2013;

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

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

• our commercialization, marketing and manufacturing capabilities and strategy;

• third-party payor reimbursement for our product candidates;

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

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

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

• the potential advantages of our product candidates;

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

• our expectations regarding licensing, acquisitions and strategic activities.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics and industry change, and depend on regulatory approvals and economic and other environmental circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. We discuss many of these risks in greater detail 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, 2013, as filed with the Securities and Exchange Commission (“SEC”) on March 26, 2014. You should not rely upon forward-looking statements as predictions of future events.

Although we believe that we have a reasonable basis for each forward-looking statement contained in this report, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the 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 are as of the date of this report. Except as required by law, we are under no duty to update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this report.

AERIE PHARMACEUTICALS, INC.

(A Development Stage Company)

Notes to the Financial Statements

(Unaudited)

1. The Company

Aerie Pharmaceuticals, Inc. (the “Company”) is a development stage pharmaceutical company focused on the discovery, development and commercialization of topical, small molecule products to treat patients with glaucoma and other diseases of the eye. Incorporated in the State of Delaware on June 22, 2005, the Company maintains its corporate headquarters in Bedminster, New Jersey, conducts research in Research Triangle Park, North Carolina, and also has an office in Newport Beach, California.

To date, the Company is in the development stage and has not yet commenced primary operations or generated product revenue. The Company’s activities since inception primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company has no current source of revenue to sustain its present activities, and it does not expect to generate revenue until and unless it receives regulatory approval of and successfully commercializes its product candidates. The Company has incurred losses and experienced negative operating cash flows since inception, and has cumulative net cash flows used in operating activities of $88.2 million and cumulative net losses of $113.4 million for the period from inception (June 22, 2005) to June 30, 2014.

The Company has funded its operations primarily through the sale of equity securities and issuance of convertible notes. In October 2013, the Company completed its initial public offering (“IPO”) and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. The Company estimates that it has sufficient funding to sustain operations through approximately mid-2016.

Accordingly, the Company will be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or commercialization efforts.

2. Significant Accounting Policies

Basis of Presentation

The Company’s interim 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 financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K. The results for the three months and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Use of Estimates

The preparation of 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 financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of money market funds, certificates of deposit, commercial paper and corporate notes 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 balance sheet. Investments are classified as long-term assets on the balance sheet if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three months and six months ended June 30, 2014 or 2013 or for the period from inception (June 22, 2005) to June 30, 2014.

4

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2014, 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 measures 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 Company’s material financial instruments consist primarily of cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses, all of which approximate their respective carrying values due to the short-term nature of these instruments.

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-10, which eliminates the concept of a development stage entity in its entirety from current accounting guidance. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2014, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, which is an amendment to the accounting guidance on income taxes. This guidance provides clarification on the financial statement presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment is effective for the Company for interim and annual periods beginning after December 15, 2013. The adoption of the provisions of this guidance did not have a material impact on the Company’s financial statements.

In February 2013, the FASB issued ASU 2013-02 Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires that public and non-public companies present information about reclassification adjustments for accumulated other comprehensive income in their annual financial statements in a note or on the face of the financial statements. Public companies are also required to provide this information in interim financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. The adoption of the provisions of this guidance did not have a material impact on the Company’s results of operations, cash flows and financial position.

Net Loss per Share Attributable to Common Stock

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

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

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

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

⁽¹⁾  In connection with the completion of the Company’s IPO, the outstanding shares of convertible preferred stock and outstanding convertible notes and accrued interest thereon were converted into 12,120,531 and 1,860,363 shares of common stock, respectively.

The Company did not hold any investments at December 31, 2013.

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:

8. Stock-based Compensation

The Company maintains two equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”) and the 2013 Omnibus Incentive Plan (the “2013 Equity Plan”). The 2005 Plan and the 2013 Equity Plan are referred to collectively as the “Plans.”

On October 30, 2013, the effective date of the 2013 Equity Plan, the 2005 Plan was frozen and no additional awards will be made under the 2005 Plan. Any shares remaining available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan. The 2013 Equity Plan provides for the granting of up to 3,229,068 equity awards for common stock of the Company. The Company granted stock options to employees to purchase 1,143,700 and 304,800 shares of common stock during the six months ended June 30, 2014 and 2013, respectively.

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

	NUMBER OF SHARES			WEIGHTED AVERAGE EXERCISE PRICE		AGGREGATE INTRINSIC VALUE
						(000’s)
Options outstanding at December 31, 2013		3,189,660		$	2.1634	$	50,386
Granted		1,143,700			20.0385
Exercised		(512,640	)		0.8295
Cancelled		(11,350	)		7.8096
Options outstanding at June 30, 2014		3,809,370		$	7.8841	$	64,325
Options exercisable at June 30, 2014		759,654		$	1.8800	$	17,388

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 re-measured at each financial reporting period until required service is performed.

Stock-based compensation expense for options granted, restricted stock and stock purchase rights are reflected in the statement of operations as follows:

	THREE MONTHS ENDED JUNE 30,				SIX MONTHS ENDED JUNE 30,				PERIOD FROM INCEPTION (JUNE 22, 2005) TO JUNE 30,
(in thousands)	2014		2013		2014		2013		2014
Research and development	$	237	$	22	$	852	$	44	$	1,252
General and administrative		2,145		215		3,452		357		6,940
Total	$	2,382	$	237	$	4,304	$	401	$	8,192

As of June 30, 2014, the Company had $26.1 million of unrecognized compensation expense related to options granted under the Plans. This cost is expected to be recognized over a weighted average period of 3.0 years as of June 30, 2014. The weighted average remaining contractual life on all outstanding options as of June 30, 2014 was 8.8 years.

Restricted Common Stock

On March 21, 2013, concurrent with the cancellation of 345,000 stock options, the Company issued 371,034 shares of restricted stock to an employee. The vesting of these awards is time-based with terms of two to four years. These restricted stock awards are subject to repurchase, such that the Company has the right, but not the obligation, to repurchase unvested shares upon the employee’s termination. As of June 30, 2014, 174,566 shares of restricted stock awards were unvested and subject to repurchase.

Compensation expense related to these restricted stock awards is based on the market value of the Company’s common stock on the date of grant and is expensed on a straight-line basis (net of estimated forfeitures) over the vesting period. The weighted average remaining contractual term for restricted stock awards as of June 30, 2014 was 1.6 years. Compensation expense related to restricted stock awards for the three months and six months ended June 30, 2014 was $97,000 and $195,000, respectively and was included in general and administrative expense.

As of June 30, 2014, the Company had $437,000 of unrecognized compensation expense, related to unvested restricted stock awards. This cost is expected to be recognized over a weighted average period of 1.6 years as of June 30, 2014.

9. Commitments and Contingencies

Lease Commitment

In June 2014, the Company entered into a lease agreement (the “Agreement”) to expand its existing headquarters located in Bedminster, New Jersey. The Agreement will provide the Company with an additional 7,000 square feet of leased office space under a lease that expires in August 2020. Additionally, as part of the Agreement, the Company extended the term of the lease on its existing headquarters from July 2018 to August 2020. Total additional rental payments under the Agreement are approximately $1.5 million and are expected to be incurred from August 2014 to August 2020.

Litigation

The Company is not party to any known litigation, is not aware of any unasserted claims and does not have contingency reserves established for any litigation liabilities.

Contract Service Providers

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

10. Related-Party Transactions

In connection with the completion of the Company’s IPO in October 2013, the outstanding shares of convertible preferred stock and outstanding convertible notes and accrued interest thereon were converted into 12,120,531 and 1,860,363 shares of common stock, respectively. Prior to their conversion into common stock in connection with the IPO, the Company’s convertible notes were due to holders of the Company’s convertible preferred stock. Interest expense on those obligations for the three months and six months ended June 30, 2013 was $161,000 and $222,000, respectively.

On September 6, 2013, the Company terminated its agreement to exclusively license its intellectual property for non-ophthalmic indications to Novaer Holding, Inc. Since September 6, 2013, the Company owns all of the worldwide rights to its current product candidates for all indications, both ophthalmic and non-ophthalmic.

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

The following discussion and analysis should be read in conjunction with our unaudited 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, 2013, as filed with the SEC on March 26, 2014. 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, 2013 for a discussion of certain risk factors applicable to our business, financial condition and results of operations. Past operating results are not necessarily indicative of operating results in any future periods.

Overview

We are a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with glaucoma and other diseases of the eye. Our lead product candidate, once-daily, triple-action Rhopressa™, successfully completed a Phase 2b clinical trial in patients with open-angle glaucoma and ocular hypertension in May 2013. The first patients enrolled in our Phase 3 registration trials of Rhopressa™ were dosed in early July 2014. There will be two trials conducted in the United States and one safety-only study in Canada. We are also developing a second product candidate, once-daily, quadruple-action Roclatan™, which is a fixed-dose combination of Rhopressa™ and latanoprost, the most commonly prescribed drug for the treatment of patients with glaucoma. Roclatan™ successfully completed a Phase 2b clinical trial in June 2014 and preparatory steps for Phase 3 registration trials have commenced. We are focused on glaucoma because we believe our product candidates provide important new opportunities to improve the treatment of the disease.

We are developing Rhopressa™ as the first of a new class of compounds that is designed to lower intraocular pressure, or IOP, through novel biochemical targets. By inhibiting these targets, we believe Rhopressa™ reduces IOP via three separate mechanisms of action, or MOAs: (i) it increases fluid outflow through the trabecular meshwork, the diseased tissue of the eye, (ii) it reduces episcleral venous pressure, which represents the pressure of the blood in the episcleral veins of the eye where eye fluid drains into the bloodstream, and (iii) it reduces the production of eye fluid. Roclatan™ is a combination of Rhopressa™ and latanoprost and is designed to lower IOP through the same three MOAs as Rhopressa™ and, with a fourth MOA, through the ability of latanoprost to increase fluid outflow through the uveoscleral pathway, the eye’s secondary drain. In addition to our primary product candidates, Rhopressa™ and Roclatan™, we are in the preclinical development stage with AR-13533.

We have incurred net losses since our inception in June 2005. Our operations to date have been limited to research and development and raising capital. As of June 30, 2014, we had a deficit accumulated during the development stage of $113.6 million. We recorded net losses of $11.8 million and $18.5 million for the three months and six months ended June 30, 2014, respectively, and net losses of $6.3 million and $10.1 million for the three months and six months ended June 30, 2013, respectively. We anticipate that a substantial portion of our capital resources and efforts in the foreseeable future will be focused on completing development activities, obtaining regulatory approval and preparing for potential commercialization of our product candidates.

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

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

We expect our research and development expenses to increase as we initiate and conduct clinical trials for our Rhopressa™ and Roclatan™ product candidates and pursue regulatory approval. As we prepare for commercialization, we will likely incur significant commercial, sales, marketing and outsourced manufacturing expenses. Since our IPO in October 2013, we are also incurring additional expenses associated with operating as a public company. As a result, we expect to continue to incur significant and increasing operating losses at least for the next several years. To date, we have not generated product revenue and we do not expect to generate product revenue unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates.

10

We estimate that we have sufficient funding to sustain operations through approximately mid-2016 but that the cash and cash equivalents and investments on our balance sheet as of June 30, 2014 will not be sufficient to enable us to complete all necessary development or commercially launch our product candidates. Accordingly, we will be required to obtain further funding through public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our research and development programs or commercialization efforts.

Financial Overview

Revenue

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

General and Administrative Expenses

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

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

Research and Development Expenses

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

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

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

• costs associated with preclinical activities and development activities;

• costs associated with regulatory operations; and

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

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

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

11

The following table shows our research and development expenses by product candidate and type of activity for the three months and six months ended June 30, 2014 and 2013:

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

Total research and development expense	$	6,676	$	3,173	$	12,046	$	6,328

From inception through June 30, 2014, we did not incur any direct non-clinical or direct clinical costs for AR-13533. Costs for this product candidate were primarily comprised of internal personnel costs and were included in unallocated costs. Discontinued product candidates relate to previously developed AR-12286 and related compounds, which did not meet their primary endpoints in clinical trials. We may continue to incur immaterial costs for these discontinued product candidates related to the enforcement of patent protection and general record maintenance.

From inception through June 30, 2014, we have incurred approximately $67.1 million in research and development expenses.

Research and development activities associated with the discovery and development of new drugs and products for the treatment of diseases of the eye are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase as we conduct future clinical trials for our product candidates, or if the FDA requires us to conduct additional trials for approval.

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

• number of trials required for approval;

• number of sites included in the trials;

• length of time required to enroll suitable patients;

• number of patients that participate in the trials;

• drop-out or discontinuation rates of patients;

• duration of patient follow-up;

• costs related to compliance with regulatory requirements;

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

• phase of development of the product candidate; and

• efficacy and safety profile of the product candidate.

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

12

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 of our products. We may never succeed in achieving regulatory approval for one or more of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of future preclinical studies and clinical trials, uncertainties in the clinical trial enrollment rate and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including efficacy and tolerability profiles, manufacturing capability, competition, and commercial viability.

Other Income (Expense), Net

Other income consists of interest earned on our cash and cash equivalents and investments as well as the net proceeds from the sale of our net operating loss tax benefits for the state of New Jersey. Interest income is not considered significant to our historical financial statements and consists of interest earned on our cash and cash equivalents. Refer to Note 3 to our unaudited financial statements appearing elsewhere in this report for further information.

Other expense consists of interest accrued under convertible notes, amortization of debt discounts and non-cash expense related to changes in the fair value of our warrants liability arising from the stock purchase warrants. Upon closing of the IPO in October 2013, the principal and accrued interest outstanding under our convertible notes were converted into 1,860,363 shares of common stock at a conversion price equal to the IPO price of $10.00 per share. Prior to the IPO, we recognized all of our outstanding warrants as liabilities on our balance sheet as they were subject to price protection provisions. The liability was revalued at each reporting period and changes in the fair value of the warrant liability were included as a component of Other income (expense), net. Upon closing of the IPO, the remaining outstanding warrants to purchase convertible preferred stock were automatically converted into warrants to purchase common stock and all price protection provisions associated with the warrants were removed, at which time the liabilities were revalued and reclassified to equity.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The preparation of 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 the fair value measurement of stock purchase warrants, stock-based compensation and certain research and development expenses. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are more fully described in Note 2 to our unaudited financial statements included elsewhere in this report and Note 2 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013.

13

General and administrative expenses

General and administrative expenses increased by $3.2 million for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013. This increase was primarily attributable to an increase of $2.2 million in personnel costs, including employee stock-based compensation expense of $1.9 million and new salaried employees and related expenses of $0.3 million. As a result of increased audit fees, legal fees, board expenses and other business related activities in connection with operating as a public company, fees related to professional, consulting and service providers increased by $0.9 million and travel expenses increased by $0.1 million.

Research and development expenses

During the three months ended June 30, 2014, our research and development activity was primarily associated with the preparation of Phase 3 registration trials for Rhopressa^TM and the completion of the Phase 2b clinical trial of Roclatan^TM. Research and development expenses increased by $3.5 million for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013. Costs for Rhopressa^TM increased by $3.1 million as direct clinical costs and direct non-clinical costs increased $1.7 million and $1.4 million, respectively. Costs for Roclatan^TM increased $1.0 million as direct clinical and direct non-clinical costs increased $0.9 million and $0.1 million. Additionally, unallocated expenses including employee salary and related expenses increased by $1.0 million. Research and development expenses for product candidates for which further advancement was discontinued during the second quarter of 2013 decreased by $1.6 million.

Other income (expense), net

Other income (expense), net increased by $1.2 million for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013. The increase was mainly due to a decrease of $1.1 million in non-cash interest expense relating to the amortization of debt discounts and accrued interest and a $0.1 million decrease in non-cash expense related to the change in the fair value of warrant liabilities. Upon closing of the IPO in October 2013, the principal and accrued interest outstanding under our convertible notes were converted into 1,860,363 shares of common stock and the remaining outstanding warrants to purchase convertible preferred stock were automatically converted into warrants to purchase common stock at which time the liabilities were revalued and reclassified to equity.

Comparison of the Six Months Ended June 30, 2014 and 2013

The following table summarizes the results of our operations for the six months ended June 30, 2014 and 2013:

General and administrative expenses

General and administrative expenses increased by $5.4 million for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013. This increase was primarily attributable to an increase of $3.7 million in personnel costs, including employee stock-based compensation expense of $3.1 million and new salaried employees and related expenses of $0.6 million. As a result of increased audit fees, legal fees, board expenses and other business related activities in connection with operating as a public company, fees related to professional, consulting and service providers increased by $1.5 million and travel expenses increased by $0.2 million.

Research and development expenses

During the six months ended June 30, 2014, our research and development activity was primarily associated with the preparation of Phase 3 registration trials for Rhopressa^TM and the initiation and completion of the Phase 2b clinical trial of Roclatan^TM. Research and development expenses increased by $5.7 million for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013. Costs for Rhopressa^TM increased by $4.5 million as direct non-clinical costs and direct clinical costs increased $3.6 million and $0.9 million, respectively. Costs for Roclatan^TM increased $2.0 million as direct clinical and direct non-clinical costs increased $1.9 million and $0.1 million. Additionally, unallocated expenses including employee salary and related expenses increased by $2.2 million. Research and development expenses for product candidates for which further advancement was discontinued during the second quarter of 2013 decreased by $3.0 million.

14

Other income (expense), net

Other income (expense), net increased by $2.7 million for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013. The increase was mainly due to a $1.0 million increase in income generated as a result of our participation in the New Jersey Economic Development Authority’s sponsored Technology Business Tax Certificate Transfer Program. Additionally, there was a decrease of $1.4 million in non-cash interest expense relating to the amortization of debt discounts and accrued interest and a $0.3 million decrease in non-cash expense related to the change in the fair value of warrant liabilities. Upon closing of the IPO in October 2013, the principal and accrued interest outstanding under our convertible notes were converted into 1,860,363 shares of common stock and the remaining outstanding warrants to purchase convertible preferred stock were automatically converted into warrants to purchase common stock at which time the liabilities were revalued and reclassified to equity.

Liquidity and Capital Resources

Since our inception, we have funded operations primarily through the sale of equity securities, including our IPO, and the issuance of convertible promissory notes. We have incurred losses and experienced negative operating cash flows since our inception and anticipate that we will continue to incur losses for at least the next several years. For the period from inception (June 22, 2005) to June 30, 2014, we have cumulative net cash used in operating activities of $88.2 million and cumulative net losses of $113.4 million.

As of June 30, 2014, our principal sources of liquidity were our cash and cash equivalents and investments, which totaled approximately $56.6 million.

We believe that our cash and cash equivalents and investments as of June 30, 2014 will be sufficient to fund our operations through approximately mid-2016. Our ability to continue as a going concern will depend, in large part, on our ability to obtain and maintain the necessary capital resources to fund our business and generate positive cash flow from operations, neither of which is certain.

On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. We received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. Prior to our IPO, we raised net cash proceeds of $78.6 million from the private placement of $43.8 million of convertible preferred stock and $34.8 million of convertible notes. Subsequent to their issuance, we paid $0.5 million in cash payments on the convertible notes, $16.2 million of the convertible notes were converted into shares of convertible preferred stock, which were subsequently converted into shares of common stock in connection with our IPO, and $18.0 million of the convertible notes were converted into shares of common stock in connection with our IPO. In connection with our IPO, all outstanding shares of convertible preferred stock were converted into shares of common stock.

The following table summarizes our sources and uses of cash:

	SIX MONTHS ENDED JUNE 31,
	2014			2013
	(unaudited)
	(in thousands)
Net cash (used in) provided by:
Operating activities	$	(12,921	)	$	(7,577	)
Investing activities		(28,926	)		(17	)
Financing activities		74			7,046
Net change in cash and cash equivalents	$	(41,773	)	$	(548	)

During the six months ended June 30, 2014 and 2013, our operating activities used net cash of $12.9 million and $7.6 million, respectively. The use of net cash in each of these periods primarily resulted from our net losses. The increase in net loss from operations for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 was due to increases in general and administrative and research and development expenses. For the six months ended June 30, 2014 and 2013, we received $2.3 million and $1.3 million, respectively, of cash proceeds from the sale of deferred state tax benefits to an unrelated third party, which decreased net loss for the respective periods.

During the six months ended June 30, 2014, our investing activities used net cash of $28.9 million primarily related to purchases of available-for-sale investments of $31.9 million, which was partially offset by maturity of available-for-sale investments of $3.0 million. During the six months ended June 30, 2013, our investing activities primarily related to purchases of office furnishings and equipment to accommodate our business growth.

During the six months ended June 30, 2014 and 2013, our financing activities provided net cash of $0.1 million and $7.0 million, respectively. The net cash provided by financing activities during the six months ended June 30, 2014 was primarily related to proceeds of $0.1 million from the exercise of stock purchase rights under our employee stock purchase plan. The net cash provided by financing activities during the six months ended June 30, 2013 was related to proceeds of $7.5 million from the sale of convertible notes, partially offset by $0.5 million in payments made in preparation for our IPO.

Operating Capital Requirements

We expect to incur increasing operating losses for at least the next several years as we conduct Phase 3 clinical trials for Rhopressa™ and prepare for Phase 3 clinical trials for Roclatan™. We expect that our existing cash and cash equivalents and investments will enable us to fund our operating expenses and capital expenditure requirements through approximately mid-2016 and that we will need to raise additional capital to fund Phase 3 clinical development of Roclatan™ and our operations.

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

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

• costs of any follow-on development or products;

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

• outcome, timing and costs of seeking regulatory approval;

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

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

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

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

We expect that we will need to obtain substantial additional funding in order to obtain regulatory approvals for any product candidates and support commercialization and ongoing business activities. 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. In addition, debt financing, if available, would result in increased fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business. If we are unable to raise capital when needed or on acceptable terms, we could be forced to significantly delay, scale back or discontinue the development or commercialization of our product candidates.

We will also continue to incur costs as a public company that we have not previously incurred or previously incurred at lower rates, including but not limited to, increased costs and expenses for directors fees, increased personnel costs, increased directors and officers insurance premiums, audit and legal fees, investor relations fees, expenses for compliance with reporting requirements under the Exchange Act and rules implemented by the SEC and NASDAQ and various other costs.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations at June 30, 2014:

	TOTAL		LESS THAN 1 YEAR		1 TO 3 YEARS		3 TO 5 YEARS		MORE THAN 5 YEARS
	(in thousands)
Operating lease obligations(1)	$	2,294	$	470	$	666	$	692	$	466

(1) Our operating lease obligations are related to our corporate headquarters in New Jersey, research facility in North Carolina and office in Newport Beach, California.

In June 2014, we entered into a lease agreement (the “Agreement”) to expand our existing headquarters located in Bedminster, New Jersey. The Agreement will provide us with an additional 7,000 square feet of leased office space under a lease that expires in August 2020. Additionally, as part of the Agreement, we extended the term of the lease on our existing headquarters from July 2018 to August 2020. Total additional rental payments under the Agreement are approximately $1.5 million and are expected to be incurred from August 2014 to August 2020.

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

Off-Balance Sheet Arrangements

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

Jumpstart Our Business Startups Act of 2012

The Jumpstart Our Business Startups Act of 2012 provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. Our cash and cash equivalents as of June 30, 2014, totaled $27.9 million and consisted primarily of cash and money market funds with original maturities of three months or less from the date of purchase. Our investments totaled $28.7 million as of June 30, 2014 and consisted of certificates of deposit, commercial paper and corporate notes. We had cash and cash equivalents on hand of $69.6 million as of December 31, 2013. Given the short-term nature of our cash equivalents and investments, 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. We do not have any foreign currency or 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 June 30, 2014, the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act, is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Changes in Internal Control Over Financial Reporting

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

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any legal proceedings.

Item 1A. Risk Factors

There have been no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

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

Unregistered Sales of Equity Securities

None.

Use of Proceeds from Registered Securities

On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The shares were registered under the Securities Act on a Registration Statement on Form S-1 (Registration No. 333-191219). The SEC declared the registration statement effective on October 24, 2013. Shares of our common stock began trading on the NASDAQ Global Market on October 25, 2013.

We received net proceeds from the IPO of $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. None of the expenses associated with the IPO were paid to directors, officers, persons owning 10% or more of any class of equity securities, or their respective associates, or to our affiliates.

As of June 30, 2014, we have used a portion of the proceeds from the sale of these securities to fund the direct clinical and non- clinical costs associated with the development of our lead product candidates and for working capital and general corporate purposes. We have invested the balance of the net proceeds from the IPO in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities. There has been no material change in our planned use of the net proceeds from our IPO as described in our final prospectus filed with the SEC on October 28, 2013 pursuant to Rule 424(b) under the Securities Act.

The Company

1. The Company

Aerie Pharmaceuticals, Inc. (the “Company”) is a development stage pharmaceutical company focused on the discovery, development and commercialization of topical, small molecule products to treat patients with glaucoma and other diseases of the eye. Incorporated in the State of Delaware on June 22, 2005, the Company maintains its corporate headquarters in Bedminster, New Jersey, conducts research in Research Triangle Park, North Carolina, and also has an office in Newport Beach, California.

To date, the Company is in the development stage and has not yet commenced primary operations or generated product revenue. The Company’s activities since inception primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company has no current source of revenue to sustain its present activities, and it does not expect to generate revenue until and unless it receives regulatory approval of and successfully commercializes its product candidates. The Company has incurred losses and experienced negative operating cash flows since inception, and has cumulative net cash flows used in operating activities of $88.2 million and cumulative net losses of $113.4 million for the period from inception (June 22, 2005) to June 30, 2014.

The Company has funded its operations primarily through the sale of equity securities and issuance of convertible notes. In October 2013, the Company completed its initial public offering (“IPO”) and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. The Company estimates that it has sufficient funding to sustain operations through approximately mid-2016.

Accordingly, the Company will be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or commercialization efforts.

Significant Accounting Policies

2. Significant Accounting Policies

Basis of Presentation

The Company’s interim 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 financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K. The results for the three months and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Use of Estimates

The preparation of 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 financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of money market funds, certificates of deposit, commercial paper and corporate notes 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 balance sheet. Investments are classified as long-term assets on the balance sheet if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three months and six months ended June 30, 2014 or 2013 or for the period from inception (June 22, 2005) to June 30, 2014.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2014, 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 measures 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 Company’s material financial instruments consist primarily of cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses, all of which approximate their respective carrying values due to the short-term nature of these instruments.

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-10, which eliminates the concept of a development stage entity in its entirety from current accounting guidance. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2014, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, which is an amendment to the accounting guidance on income taxes. This guidance provides clarification on the financial statement presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment is effective for the Company for interim and annual periods beginning after December 15, 2013. The adoption of the provisions of this guidance did not have a material impact on the Company’s financial statements.

In February 2013, the FASB issued ASU 2013-02 Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires that public and non-public companies present information about reclassification adjustments for accumulated other comprehensive income in their annual financial statements in a note or on the face of the financial statements. Public companies are also required to provide this information in interim financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. The adoption of the provisions of this guidance did not have a material impact on the Company’s results of operations, cash flows and financial position.

Net Loss per Share Attributable to Common Stock

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

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

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

Stock-based Compensation

8. Stock-based Compensation

The Company maintains two equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”) and the 2013 Omnibus Incentive Plan (the “2013 Equity Plan”). The 2005 Plan and the 2013 Equity Plan are referred to collectively as the “Plans.”

On October 30, 2013, the effective date of the 2013 Equity Plan, the 2005 Plan was frozen and no additional awards will be made under the 2005 Plan. Any shares remaining available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan. The 2013 Equity Plan provides for the granting of up to 3,229,068 equity awards for common stock of the Company. The Company granted stock options to employees to purchase 1,143,700 and 304,800 shares of common stock during the six months ended June 30, 2014 and 2013, respectively.

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

	NUMBER OF SHARES			WEIGHTED AVERAGE EXERCISE PRICE		AGGREGATE INTRINSIC VALUE
						(000’s)
Options outstanding at December 31, 2013		3,189,660		$	2.1634	$	50,386

Options exercisable at June 30, 2014		759,654		$	1.8800	$	17,388

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 re-measured at each financial reporting period until required service is performed.

Stock-based compensation expense for options granted, restricted stock and stock purchase rights are reflected in the statement of operations as follows:

	THREE MONTHS ENDED JUNE 30,				SIX MONTHS ENDED JUNE 30,				PERIOD FROM INCEPTION (JUNE 22, 2005) TO JUNE 30,

Total	$	2,382	$	237	$	4,304	$	401	$	8,192

As of June 30, 2014, the Company had $26.1 million of unrecognized compensation expense related to options granted under the Plans. This cost is expected to be recognized over a weighted average period of 3.0 years as of June 30, 2014. The weighted average remaining contractual life on all outstanding options as of June 30, 2014 was 8.8 years.

Restricted Common Stock

On March 21, 2013, concurrent with the cancellation of 345,000 stock options, the Company issued 371,034 shares of restricted stock to an employee. The vesting of these awards is time-based with terms of two to four years. These restricted stock awards are subject to repurchase, such that the Company has the right, but not the obligation, to repurchase unvested shares upon the employee’s termination. As of June 30, 2014, 174,566 shares of restricted stock awards were unvested and subject to repurchase.

Compensation expense related to these restricted stock awards is based on the market value of the Company’s common stock on the date of grant and is expensed on a straight-line basis (net of estimated forfeitures) over the vesting period. The weighted average remaining contractual term for restricted stock awards as of June 30, 2014 was 1.6 years. Compensation expense related to restricted stock awards for the three months and six months ended June 30, 2014 was $97,000 and $195,000, respectively and was included in general and administrative expense.

As of June 30, 2014, the Company had $437,000 of unrecognized compensation expense, related to unvested restricted stock awards. This cost is expected to be recognized over a weighted average period of 1.6 years as of June 30, 2014.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Company’s interim 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 financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K. The results for the three months and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Use of Estimates

Use of Estimates

The preparation of 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 financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from these estimates.

Investments

Investments

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of money market funds, certificates of deposit, commercial paper and corporate notes 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 balance sheet. Investments are classified as long-term assets on the balance sheet if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the three months and six months ended June 30, 2014 or 2013 or for the period from inception (June 22, 2005) to June 30, 2014.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of June 30, 2014, 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

Fair Value Measurements

The Company measures 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 Company’s material financial instruments consist primarily of cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses, all of which approximate their respective carrying values due to the short-term nature of these instruments.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-10, which eliminates the concept of a development stage entity in its entirety from current accounting guidance. The new standard is effective for the Company for interim and annual periods beginning after December 15, 2014, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, which is an amendment to the accounting guidance on income taxes. This guidance provides clarification on the financial statement presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment is effective for the Company for interim and annual periods beginning after December 15, 2013. The adoption of the provisions of this guidance did not have a material impact on the Company’s financial statements.

In February 2013, the FASB issued ASU 2013-02 Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires that public and non-public companies present information about reclassification adjustments for accumulated other comprehensive income in their annual financial statements in a note or on the face of the financial statements. Public companies are also required to provide this information in interim financial statements. The new disclosure requirements are effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. The adoption of the provisions of this guidance did not have a material impact on the Company’s results of operations, cash flows and financial position.

Net Loss per Share Attributable to Common Stock

Net Loss per Share Attributable to Common Stock

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

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

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

Fair Value Measurements

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:
