Item 8.01. Other Events.

As previously disclosed, on August 22, 2022, Aerie Pharmaceuticals, Inc., a Delaware corporation ("Aerie", the "Company", "we", "our" or "us"), entered into an Agreement and Plan of Merger (such agreement, as it may be amended, modified or supplemented from time to time, the "Merger Agreement") with Alcon Research, LLC, a Delaware limited liability company ("Alcon"), and Lyon Merger Sub, Inc., a Delaware corporation and a wholly owned direct subsidiary of Alcon ("Merger Sub"). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions described therein, Merger Sub will merge with and into Aerie, with Aerie surviving the merger as a wholly owned subsidiary of Alcon (the "Merger"). On September 21, 2022, Aerie filed a preliminary proxy statement (the "Preliminary Proxy Statement") with the Securities and Exchange Commission ("SEC"), and on October 7, 2022, Aerie filed a definitive proxy statement (the "Proxy Statement") with the SEC, in each case, in connection with the Merger.

Since the filing of the Preliminary Proxy Statement, three complaints have been filed in the United States District Court for the Southern District of New York by purported Aerie stockholders against Aerie and members of Aerie's board of directors (the "Aerie Board") in connection with the Merger: Stein v. Aerie Pharmaceuticals, Inc., et al., Case No. 1:22-cv-08103(filed September 22, 2022) (S.D.N.Y.); O'Dell v. Aerie Pharmaceuticals, Inc., et al., Case No. 1:22-cv-08261(filed September 27, 2022) (S.D.N.Y.); and Weiss v. Aerie Pharmaceuticals, Inc., et al., Case No. 1:22-cv-09235(filed October 27, 2022) (S.D.N.Y.) (collectively, the "Stockholder Litigation"). Each of the complaints in the Stockholder Litigation alleges that, among other things, the Preliminary Proxy Statement and/or the Proxy Statement omitted certain material information in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14a-9promulgated thereunder. In addition, Aerie has received from certain purported Aerie stockholders several demand letters alleging similar insufficiencies in the Preliminary Proxy Statement and/or the Proxy Statement as those noted in the complaints referenced above (such demand letters, collectively with the Stockholder Litigation, the "Litigation Matters"). The plaintiffs in the Stockholder Litigation seek various remedies, including an order enjoining the defendants from proceeding with the Merger, requiring the defendants to disclose allegedly material information that was allegedly omitted from the Proxy Statement, rescinding the Merger in the event that it is consummated or granting rescissory damages, declaring that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9promulgated thereunder, awarding costs, including attorneys' and expert fees and expenses, and granting such other and further relief as the court may deem just and proper.

Aerie believes that the claims asserted in the Litigation Matters are without merit and that no additional disclosures were or are required under applicable laws. However, in order to avoid the risk of the Litigation Matters delaying or adversely affecting the Merger and to minimize the costs, risks, and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, Aerie has determined to voluntarily make the following supplemental disclosures to the Proxy Statement, as described in this Current Report on Form 8-K. Nothingin this Current Report on Form 8-Kshall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein.

These supplemental disclosures will not change the consideration to be paid to Aerie stockholders in connection with the Merger or the timing of the special meeting of Aerie stockholders (the "Special Meeting") to be held virtually on November 17, 2022, beginning at 8:00 a.m. Eastern Time. The Special Meeting can be accessed by visiting www.virtualshareholdermeeting.com/AERI2022SM. The Aerie Board continues to unanimously recommend that you vote "FOR" the proposals to be voted on at the Special Meeting described in the Proxy Statement.

The disclosure on pages 1 through 9 of the Proxy Statement in the section entitled "Summary-Opinion of Goldman Sachs & Co LLC" is hereby supplemented by revising the second paragraph of such section on page 6 of the Proxy Statement as follows:

The full text of the written opinion of Goldman Sachs, dated August 22, 2022, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B. Goldman Sachs provided advisory services and its opinion for the information and assistance of the Board in connection with its consideration of the Merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Aerie's common stock should vote with respect to the Merger or any other matter. Pursuant to an engagement letter between Aerie and Goldman Sachs, Aerie has agreed to pay Goldman Sachs a transaction fee of approximately$25.50million$20.0 million, $2.0 million of which became payable at announcement of the Merger, and the remainder of which is contingent upon consummation of the Merger.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the second paragraph of such section on page 23 of the Proxy Statement as follows:

As part of the Board's regular evaluation of potential strategic opportunities, Aerie management has periodically engaged in discussions with participants in the biopharmaceutical and healthcare industries regarding potential opportunities for business combinations, acquisitions, licensing transactions, commercial arrangements, and other financial and strategic transactions for Aerie, regularly updating the Board on such discussions. As described more fully below, in the course of such discussions, Aerie has periodically entered into confidentiality agreements with potential strategic transaction counterparties to facilitate such discussions. Additionally, representatives of an internationally recognized investment bank, which served as Aerie's financial advisor through October 2021 (the "Prior Financial Advisor"), had periodically reviewed with the Board market views with respect to Aerie, as well as strategic updates within the broader biopharmaceutical industry generally. The Prior Financial Advisor performed customary financial advisory services for Aerie on a periodic basis, including reviewing with the Board market views with respect to Aerie, providing the Board with strategic updates within the broader biopharmaceutical industry generally, reviewing Aerie's defensive profile, and discussing various potential strategic alternatives with Aerie management and the Board, including certain of the proposals described below.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the fourth full paragraph of such section on page 26 of the Proxy Statement as follows:

The Board met twice during mid-April2021. During such meetings, the Board discussed, among other things, (i) Alcon's request for valuation guidance, (ii) the potential use of a contingent value right (a "CVR") tied to the read-outof topline data from the COMET-1Phase 2b clinical trial of AR-15512expected in the third quarter of 2021, and (iii) the status of a potential collaboration transaction in respect of Aerie's glaucoma franchise in Europe. During this period, at the request of the Board, Aerie management updated the December 2020 Forecasts (taking into account management's pro forma assumptions regarding such a European collaboration transaction and including management estimates relating to projected revenue for Aerie's AR-14034pipeline product candidate). Aerie management presented such updated management forecasts to the Board at a meeting held on April 16, 2021, during which the Prior Financial Advisor also provided the Board with an updated preliminary financial analysis for Aerie based upon such updated management forecast scenarios. The Board engaged in discussion with Aerie management regarding the updated forecasts and the assumptions underlying such updated forecasts. At a meeting of the Board held on April 20, 2021, the Board discussed with Aerie management the execution of Aerie's business plan and corporate goals. Based on Aerie management's views on such execution, the valuation range for Aerie resulting from Aerie management's forecast scenarios, and the Prior Financial Advisor's preliminary financial analysis for Aerie previously presented to the Board based on such management forecast scenarios, the Board instructed the Prior Financial Advisor to inform J.P. Morgan that the Board would be willing to engage with Alcon with respect to a potential transaction at a price range per share of common stock meaningfully in the $30's and with a CVR tied to the clinical research data readout for AR-15512that would result in a total valuation, upon achievement of the applicable milestone(s) underlying the CVR, of approximately $40 per share of common stock. On April 12, 2021, the Prior Financial Advisor provided the Board with information concerning its relationships with Alcon over the prior two-yearperiod, noting that the financial advisory business of the Prior Financial Advisor had not entered into any engagement agreements with, and had not received any fees from, Alcon during such two-yearperiod.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the fourth full paragraph of such section on page 27 of the Proxy Statement as follows:

On June 21, 2021, the Prior Aerie Chair/CEO met with Mr. Ball at Mr. Ball's request. At that meeting, the Prior Aerie Chair/CEO and Mr. Ball discussed the April 1, 2021 Proposal and the Prior Aerie Chair/CEO reiterated the Board's valuation feedback by noting that, were Alcon to reengage, Alcon would need to promptly finalize its due diligence in light of Aerie's other available strategic alternatives, including Aerie's potential 2021 consummation of a collaboration transaction in respect of Aerie's glaucoma franchise in Europe. Thereafter, on June 24, 2021, the Board held a meeting attended by representatives of Fried Frank and Aerie management at which the Prior Aerie Chair/CEO provided the Board with a summary of his recent discussions with Mr. Ball. At the direction of the Board, on June 25, 2021, the Prior Aerie Chair/CEO had a follow-upcall with Mr. Ball in which the Prior Aerie Chair/CEO further indicated that in order for Aerie to meet its other strategic priorities, should Alcon wish to reopen negotiations with respect to a potential transaction, Alcon should submit an updated proposal as soon as possible and that a transaction price of $32.00-34.00in cash per share of common stock plus a $5.00 per share CVR may be sufficient to consummate a transaction between the parties. During late June 2021, Aerie management and the Prior Financial Advisor finalized the terms of the Prior Financial Advisor's engagement letter, which such engagement letter included a customary "tail" fee payable to the Prior Financial Advisor, and the engagement letter was entered into by Aerie and the Prior Financial Advisor on June 29, 2021. The engagement letter between Aerie and the Prior Financial Advisor, as amended through October 20, 2022, provides for a transaction fee of approximately $20.0 million, approximately $3.5 million of which became payable at the announcement of the Merger, and the remainder of which is contingent upon consummation of the Merger. In addition, Aerie agreed, pursuant to the terms of the engagement letter between Aerie and the Prior Financial Advisor, to customary indemnification and expense reimbursement provisions.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the fifth full paragraph of such section on page 31 of the Proxy Statement as follows:

On October 1, 2021, the Board held a meeting attended by representatives of Goldman Sachs and Fried Frank. During the meeting, the Board was provided with a summary of Aerie management's updated financial forecasts, which included two forecast scenarios known as Case 1 and Case 2 (the "October 2021 Forecasts"), and which had been preliminarily prepared by Aerie's Interim Executive Chairman with input from additional members of Aerie management. The Board engaged in discussion with Aerie management regarding Aerie management's October 2021 Forecasts, and the Board did not adopt these forecasts and insteadrequested that theythe October 2021 Forecastsbe further updated by Aerie management taking into account certain additional assumptions, including with respect to product candidate approval probability and Aerie's future financing requirements. The Board was updated on the ongoing negotiations with respect to Goldman Sachs' engagement letter, with the Board approving Aerie's continued negotiations of such engagement. The Board also engaged in discussion regarding Aerie's ongoing negotiations with Santen in respect of the Santen Transaction, including key terms such as upfront consideration, milestone payments, royalties, upfront costs, and operational costs.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the sixth full paragraph of such section on page 31 of the Proxy Statement as follows:

Between October 1, 2021 and October 16, 2021, Aerie management engaged with Goldman Sachs on the Goldman Sachs engagement letter and the Board approved the final terms of the engagement letter and Aerie's termination of its engagement letter with the Prior Financial Advisor. During that period, Goldman Sachs provided the Board with certain information about its relationships with Alcon over the prior two-yearperiod. An engagement letter between Aerie and Goldman Sachs was executed on October 22, 2021. Aerie engaged Goldman Sachs, and terminated its engagement of the Prior Financial Advisor, to obtain fresh perspectives on Aerie's potential strategic alternatives.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the fifth full paragraph of such section on page 32 of the Proxy Statement as follows:

On November 19, 2021, the Board held a meeting attended by representatives of Goldman Sachs, Fried Frank, and Aerie management. The Board reviewed the material terms of the Santen Transaction and the status of the Aerie's ongoing negotiations with Santen. Dr. McGraw provided the Board with a review of the updates toan overview of the updatedthe draftmanagement projections for Aerie that had been discussed with the Board at the October 1, 2021 meetingand noted certain differences between the forecasts prepared by Aerie's prior management team and the current Aerie management team. After discussion, the Board determined not to adopt these forecasts and insteadthat the person to be appointed as Aerie's new Chief Executive Officer should have the opportunity to review and update Aerie's strategic plan and provide input on Aerie's updated management projections. The Board discussed with representatives of Goldman Sachs, Fried Frank and Aerie management the November 15, 2021 Proposal from Alcon as well as the current status of the Santen Transaction, including that Alcon had conditioned the November 15, 2021 Proposal on Aerie not entering into the Santen Transaction. The Board discussed that, in connection with the submission of the November 15, 2021 Proposal, Alcon had communicated to Aerie that (i) the price in Alcon's prior July 23, 2021 Proposal ($28.00 in cash per share of common stock plus a $4.00 per share CVR) would likely have been lowered by Alcon upon completion of its due diligence based on Aerie's recent commercialization results for Rhopressa® and Rocklatan®, and (ii) Alcon would not have moved forward with the July 23, 2021 Proposal prior to Aerie's release of results from the COMET-1Phase 2b clinical trial of AR-15512in mid-September2021. The Board determined, given Aerie's advanced negotiations with Santen on the Santen Transaction and Aerie's near-term liquidity requirements (taking into account Aerie's cash position, cash-burn metrics, and need to fund the commencement of Phase 3 clinical trials for AR-15512and further clinical trials for AR-1105),that Aerie should prioritize finalizing the Santen Transaction and that the November 15, 2021 Proposal from Alcon did not, at that time, reflect a valuation of Aerie that the Board believed was sufficient in order to transact particularly given the requirement, expressed in Alcon's November 15, 2021 Proposal, that Aerie abandon the Santen Transaction as a condition of engaging with Alcon in respect of its proposal.

The disclosure on pages 23 through 39 of the Proxy Statement in the section entitled "The Merger-Background of the Merger" is hereby supplemented by revising the last paragraph of such section on page 39 of the Proxy Statement as follows:

Later that day, Aerie and Alcon executed the Merger Agreement and issued a joint press release announcing the execution of the Merger Agreement. Prior to the entry into the Merger Agreement and through the date of this filing, and except for the rights of Aerie security holders to receive consideration for their securities pursuant to the terms and conditions of the Merger Agreement, there has been no material agreement, arrangement or understanding between Aerie or any of its executive officers or directors, on the one hand, and Alcon or any of its executive officers or directors, on the other hand, regarding post-closing employment or directorships for, or compensation of, Aerie's executive officers or directors, and there were no material discussions regarding the same prior to the entry into the Merger Agreement. Beginning in late October 2022, Alcon and Casey C. Kopczynski, Ph.D., Aerie's Chief Innovation Officer, Head of Research and External Innovation, have had preliminary discussions regarding a potential role for Dr. Kopczynski following Closing.

(dollars in millions)

The disclosure on pages 44 through 48 of the Proxy Statement in the section entitled "The Merger-Financial Projections" is hereby supplemented by revising the first full paragraph set forth on page 48 of the Proxy Statement as follows:

EBIT and unlevered free cash flow contained in the Forecasts set forth above are each "non-GAAPfinancial measures," which are financial performance measures that are not calculated in accordance with GAAP. These non-GAAPfinancial measures are not intended to be considered in isolation from, or as a substitute for, financial information prepared and presented in accordance with GAAP. These measures may be different from non-GAAPfinancial measures used by other companies, limiting their usefulness for comparison purposes. Furthermore, there are limitations inherent in non-GAAPfinancial measures because they exclude charges and credits that are required to be included in a GAAP presentation. Accordingly, these non-GAAPfinancial measures should be considered together with, and not as an alternative to, financial measures prepared in accordance with GAAP. In certain circumstances, including those applicable to the Forecasts, financial measures included in forecasts provided to a financial advisor and a board of directors in connection with a business combination transaction are excluded from the definition of "non-GAAPfinancial measures" under applicable SEC rules and regulations. As a result, the financial measures included in the Forecasts are not subject to SEC rules regarding disclosures of non-GAAPfinancial measures, which would otherwise require a reconciliation of a non-GAAPfinancial measure to a GAAP financial measure. Reconciliations of non-GAAPfinancial measures were not provided to or relied upon by the Board or Goldman Sachs.

The disclosure on pages 49 through 53 of the Proxy Statement in the section entitled "The Merger-Opinion of Goldman Sachs & Co LLC" is hereby supplemented by revising the paragraph entitled "Illustrative Discounted Cash Flow Analysis" beginning on page 50 of the Proxy Statement as follows:

Illustrative Discounted Cash Flow Analysis. Using the Financial Information, Goldman Sachs performed an illustrative discounted cash flow analysis on Aerie. Using a mid-yearconvention and discount rates ranging from 10.0% to 12.0%, reflecting estimates of Aerie's weighted average cost of capital, Goldman Sachs discounted to present value as of June 30, 2022 estimates of unlevered free cash flow for Aerie for the third and fourth quarters of 2022 and years 2023 through 2040 as reflected in the Final 2022 Case 1 Forecasts. No implied terminal value was calculated because the Final 2022 Case 1 Forecasts were forecasted to 2040 and management of Aerie did not forecast that Aerie would have any revenues after 2040. In addition, using discount rates ranging from 10.0% to 12.0%, reflecting estimates of Aerie's weighted average cost of capital, Goldman Sachs discounted to present value as of June 30, 2022 the estimated benefits of Aerie'sthe usage of approximately $759 million federal and foreign net operating losses as well as $674 million in state net operating losses (as of June 30, 2022)net operating losses for the third and fourth quarters of 2022 and years 2023 through 2040, as reflected in the Financial Information. Goldman Sachs derived such discount rates by application of the Capital Asset Pricing Model, which requires certain company-specific inputs, including Aerie's target capital structure weightings, the cost of long-term debt, after-taxyield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for Aerie, as well as certain financial metrics for the United States financial markets generally. Goldman Sachs derived ranges of illustrative enterprise values for Aerie by adding the ranges of the present values it derived above. Goldman Sachs then subtracted from the range of illustrative enterprise values it derived for Aerie the net debt of $131.9 million as of June 30, 2022 of Aerie as reflected in the Financial Information, as provided by the management of Aerie, to derive a range of illustrative equity values for Aerie. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of Aerie of approximately 50.4 to 50.6 million, as provided by the management of Aerie and approved for Goldman Sachs' use by the management of Aerie, to derive a range of illustrative present values per share ranging from $14.30 to $16.97.

The disclosure on pages 49 through 53 of the Proxy Statement in the section entitled "The Merger-Opinion of Goldman Sachs & Co LLC" is hereby supplemented by revising the last paragraph of such section on page 52 of the Proxy Statement as follows:

The Board selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the Merger. Pursuant to a letter agreement dated October 16, 2021, Aerie engaged Goldman Sachs to act as its financial advisor in connection with the Merger. The engagement letter between Aerie and Goldman Sachs provides for a transaction fee ofthat is estimated, based on the information available as of the date of announcement, atapproximately $25.50million$20.0 million, $2.0 million of which became payable at the announcement of the Merger, and the remainder of which is contingent upon consummation of the Merger. In addition, Aerie has agreed to reimburse Goldman Sachs for certain of its expenses, including attorneys' fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.
