Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Eyenovia, Inc. (“Eyenovia” or the “Company”) is a clinical stage ophthalmic company developing a pipeline of advanced therapeutics based on the Company’s proprietary microdose array print (MAP<sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;">TM</sup>) platform technology. The Company aims to achieve clinical microdosing of next-generation formulations of novel and existing ophthalmic pharmaceutical agents using its high-precision targeted ocular delivery system, branded the Optejet®. Optejet µ-therapeutics have the potential to replace conventional eye dropper delivery and improve safety, tolerability, patient compliance and topical delivery success for ophthalmic eye treatments. In the clinic, the Optejet has demonstrated that its targeted horizontal microdose delivery can achieve a significantly higher rate of successful ocular topical delivery compared to the established rate reported with traditional eye drops (~ <ix:nonFraction contextRef="Duration_1_1_2022_To_3_31_2022_-nbUFkCulEiWdLbyxgCCUg" decimals="2" format="ixt:numdotdecimal" id="Narr_HLSHM5EBvU-LRBc_kuKjgQ" name="eyen:PercentageOfSuccessRateOfOptejet" scale="-2" unitRef="Unit_Standard_pure_32hPaEeXwk-rKMmjY4x3Rw">90</ix:nonFraction>% vs. ~ <ix:nonFraction contextRef="Duration_1_1_2022_To_3_31_2022_-nbUFkCulEiWdLbyxgCCUg" decimals="2" format="ixt:numdotdecimal" id="Narr_-UCkiMGZxUKuJxGTQ6ljhQ" name="eyen:PercentageOfSuccessfulRateOfTraditionalEyeDrops" scale="-2" unitRef="Unit_Standard_pure_32hPaEeXwk-rKMmjY4x3Rw">50</ix:nonFraction>%). The Company’s technology is designed to achieve single-digit µl-volume physiologic drug delivery with up to a 75% reduction in ocular drug and preservative topical dosing and has demonstrated significant improvement in the therapeutic index in drugs used for presbyopia, mydriasis and intraocular pressure (“IOP”) lowering through six Phase II and Phase III trials. Conventional eye formulations lack high-precision micro-volume delivery and expose the ocular surface to approximately 300% more medication and preservatives than are physiologically indicated leading to clinically recognized ocular and non-ocular side effects. Using the Optejet, the Company is developing the next generation of smart ophthalmic therapeutics which target new indications or new combinations where there are currently no or few drug therapies approved by the U.S. Food and Drug Administration (“FDA”). The Company’s microdose therapeutics follow the FDA-designated combination product registration and regulatory process. The Company’s products are classified by the FDA as drug-device combination products with drug primary mode of action, meaning that the Center for Drug Evaluation and Research (“CDER”) is designated as the lead center with primary jurisdictional oversight. Accordingly, the product candidates are submitted to the FDA CDER for premarket review and approval under new drug applications, or NDAs. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X.

The Company does not have recurring revenue and has not yet achieved profitability. The Company expects to continue to incur cash outflows from operations. The Company expects that its research and development and general and administrative expenses will continue to increase and, as a result, it will eventually need to generate significant product revenues to achieve profitability. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern for at least one year from the date that these financial statements are issued.

The terms of such agreements may contain multiple promised goods and services, which may include (i) licenses to its intellectual property, and (ii) in certain cases, payment in connection with the manufacturing and delivery of clinical supply materials.

For collaboration arrangements that are deemed to be within the scope of Accounting Standards Codification (“ASC”) Topic 808, “Collaborative Arrangements” (“ASC 808”), the Company allocates the contract consideration between such joint operating activities and elements that are reflective of a vendor-customer relationship and, therefore, within the scope of ASC Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). The Company’s policy is to recognize amounts allocated to joint operating activities as a reduction in research and development expense.</p></ix:nonNumeric></ix:continuation></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">7</p></div></div> <div style="background-color:#000000;clear:both;height:2pt;page-break-after:always;width:88.24%;border:0;margin:30pt 5.88% 30pt 5.88%;"/><div style="max-width:100%;padding-left:5.88%;padding-right:5.88%;position:relative;"><div style="margin-top:21.6pt;min-height:14.4pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><a href="#TOC"><span style="font-style:normal;font-weight:normal;">Table of Contents</span></a></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:0pt 0pt 10pt 0pt;"><b style="font-weight:bold;">EYENOVIA, INC.</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:0pt 0pt 10pt 0pt;"><b style="font-weight:bold;">NOTES TO CONDENSED FINANCIAL STATEMENTS</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:0pt 0pt 10pt 0pt;"><b style="font-weight:bold;">(UNAUDITED)</b></p></div><div style="clear:both;max-width:100%;position:relative;"><ix:continuation id="Tb_lxNOKohi1EuAkI-QXaJNuw_cont2"><ix:continuation id="Tb_L-T2NlN9G06pSmw3Gqp4LA_cont1"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Under ASC 606, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services.

This standard is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard prospectively to modifications or exchanges occurring after the effective date of the new standard. The Company adopted ASU 2021-04 effective January 1, 2022.

Option forfeitures are accounted for at the time of occurrence. The expected term is the estimated period of time that options granted are expected to be outstanding. The Company utilizes the “simplified” method to develop an estimate of the expected term of “plain vanilla” employee option grants. The Company uses a blended volatility calculation, the components of which are the Company’s historical volatility for the period from its initial public offering through the valuation date and the average peer-group data of six comparable entities to supplement the Company’s own historical data for the preceding years in computing the expected volatility. Accordingly, the Company is utilizing an expected volatility figure based on a review of the historical volatility of comparable entities over a period of time equivalent to the expected life of the instrument being valued. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.</p><p

We aim to achieve clinical microdosing of next-generation formulations of novel and existing ophthalmic pharmaceutical agents using our high-precision targeted ocular delivery system, branded the Optejet®. Optejet µ-therapeutics have the potential to replace conventional eye dropper delivery and improve safety, tolerability, patient compliance and topical delivery success for ophthalmic eye treatments. In the clinic, the Optejet has demonstrated that its targeted horizontal microdose delivery can achieve a significantly higher rate of successful ocular topical delivery compared to the established rate reported with traditional eye drops (~ 90% vs. ~ 50%). Our technology is designed to achieve single-digit µl-volume physiologic drug delivery with up to a 75% reduction in ocular drug and preservative topical dosing and has demonstrated significant improvement in the therapeutic index in drugs used for presbyopia, mydriasis and IOP lowering through six Phase II and Phase III trials. Conventional eye formulations lack high-precision micro-volume delivery and expose the ocular surface to approximately 300% more medication and preservatives than are physiologically indicated leading to clinically recognized ocular and non-ocular side effects. Using the Optejet, we are developing the next generation of smart ophthalmic therapeutics targeting new indications or new combinations where there are currently no or few drug therapies approved by the U.S. Food and Drug Administration (the “FDA”). Our microdose therapeutics follow the FDA’s regulatory and approval process for combination products. Our products are classified by the FDA as drug-device combination products with drug primary mode of action, meaning that the Center for Drug Evaluation and Research (“CDER”), is designated as the lead center with primary jurisdictional oversight of our products. Accordingly, the product candidates are submitted to the FDA CDER for premarket review and approval under new drug applications, or NDAs.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">Our pipeline is currently focused on the late-stage development of novel, potential first-in-class therapeutic indications for an estimated 25 million potential pediatric patients with progressive myopia in the United States and an estimated over 100 million potential patients with age-related near vision impairment, or presbyopia—indications where there is tremendous unmet need and, to our knowledge, there exists only one known FDA-approved therapy, developed by Allergan. We are also developing the first microdose fixed combination ophthalmic pharmaceutical for mydriasis to address the estimated over 100 million annual comprehensive eye exams involving pupil dilation.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;">MicroPine is our first-in-class topical therapy for the treatment of progressive myopia, a back-of-the-eye ocular disease associated with pathologic axial elongation and sclero-retinal stretching. In the United States, myopia is estimated to affect approximately 25 million children, with up to five million considered to be at high risk for progressive myopia. In February 2019, the FDA accepted our investigational new drug application (“IND”) to initiate a Phase III registration trial of MicroPine (the CHAPERONE study) to reduce the progression of myopia in children. We enrolled the first patient in the CHAPERONE study in June 2019. Due to the COVID-19 pandemic, there have been delays in trial enrollment as a result of supply chain issues with our third party suppliers, which in turn diminished our inventory supply.</p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">15</p></div></div> <div style="background-color:#000000;clear:both;height:2pt;page-break-after:always;width:88.24%;border:0;margin:30pt 5.88% 30pt 5.88%;"/><div style="max-width:100%;padding-left:5.88%;padding-right:5.88%;position:relative;"><div style="margin-top:21.6pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 30pt 0pt;"><a href="#TOC"><span style="font-style:normal;font-weight:normal;">Table of Contents</span></a></p></div><div style="clear:both;max-width:100%;position:relative;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;">On October 9, 2020, we entered into the Bausch License Agreement, pursuant to which Bausch Health may develop and commercialize MicroPine in the United States and Canada. Under the terms of the Bausch License Agreement, we received an upfront payment of $10.0 million and we may receive up to a total of $35.0 million in additional payments, based on the achievement of certain regulatory and launch-based milestones. Bausch Health also will pay us royalties on a tiered basis (ranging from mid-single digit to mid-teen percentages) on gross profits from sales of MicroPine in the United States and Canada, subject to certain adjustments. Under the terms of the Bausch License Agreement, Bausch Health assumed sponsorship of the IND as well as oversight and the costs related to the ongoing CHAPERONE study.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;">MicroLine (or Apersure) is our investigational pharmacologic treatment for presbyopia. Presbyopia is a non-preventable, age-related hardening of the lens, which causes the gradual loss of the eye’s ability to focus on near objects and impairs near visual acuity. Allergan recently received FDA approval for and launched Vuity<sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;">TM</sup>, a pilocarpine solution for the treatment of presbyopia.

We have completed two Phase III trials for Mydcombi and announced positive results from these studies, known as MIST-1 and MIST-2, and have submitted an NDA to the FDA seeking approval to market the product in the U.S. In October 2021, we received a complete response letter (“CRL”) in response to our NDA, which in part informed us that pre-filled or co-packaged ophthalmic drug dispenser products like Mydcombi have been reclassified as drug-device combination products. This reclassification was based upon the U.S. Court of Appeals for the D.C. Circuit’s decision in Genus Medical Technologies v. FDA, not involving Eyenovia, which ordered that products meeting the statutory definition of a device but were previously classified by the FDA as drugs must be regulated as devices. Before this ruling, the FDA regulated pre-filled or co-packaged ophthalmic dispensers as part of the approved ophthalmic drug distributed and sold with the dispenser. After the ruling, however, the dispenser must be considered as a distinct device constituent part of a drug-device combination product. We are in the process of providing additional non-clinical device information and expect to file our NDA resubmission in the third quarter of 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;">On August 10, 2020, we entered into the Arctic Vision License Agreement, which was amended on September 14, 2021, with Arctic Vision, pursuant to which Arctic Vision may develop and commercialize MicroPine, MicroLine and Mydcombi in Greater China (mainland China, Hong Kong, Macau and Taiwan) and South Korea. Under the terms of the Arctic Vision License Agreement, as amended, we received an upfront payment of $4.25 million before any payments to Senju Pharmaceutical Co., Ltd. (“Senju”). In addition, we may receive up to a total of $43.75 million in additional payments, based on various development and regulatory milestones, including the initiation of clinical research and approvals in Greater China and South Korea, and development costs. Arctic Vision also will purchase its supply of MicroPine, MicroLine and Mydcombi from us or, for such products not supplied by us, pay us a mid-single digit percentage royalty on net sales of such products, subject to certain adjustments. We will pay between 30 and 40 percent of such payments, royalties, or net proceeds of such supply to Senju pursuant to the Exclusive License Agreement with Senju dated March 8, 2015, as amended.  For a description of the Senju license agreement, see Note 2— Summary of Significant Accounting Policies—Arctic Vision License Agreement and Note 10—Related Party Transactions—Senju License Agreement to our audited financial statements included in this Annual Report on Form 10-K on March 30, 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;">Historically, we have financed our operations principally through equity offerings. We have also generated cash through licensing arrangements and our credit facility with Silicon Valley Bank (“SVB”). However, based upon our current operating plan, there is substantial doubt about our ability to continue as a going concern for at least one year from the date that the financial statements included elsewhere in this Quarterly Report on Form 10-Q are issued. Our ability to continue as a going concern depends on our ability to complete additional licensing or business development transactions or raise additional capital, through the sale of equity or debt securities to support our future operations. If we are unable to secure additional capital, we may be required to curtail our research and development initiatives and take additional measures to reduce costs.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:32.4pt;margin:0pt 0pt 12pt 0pt;">Our net losses were $7.3 million and $5.4 million for the three months ended March 31, 2022 and 2021.

a decrease of $0.6 million, or 14.0%, as compared to $4.3 million recorded for the three months ended March 31, 2021. The decrease was primarily attributable to a $1.1 million decrease in direct clinical and non-clinical expenses primarily due to production and testing for Mydcombi and the formulation of MicroLine in 2021, whereas no new batches were manufactured in 2022, offset by an increase of $0.5 million in personnel-related expenses resulting from new hires and stock-based compensation expense.</p><p

an increase of $1.3 million, or 59.1%, as compared to $2.2 million recorded for the three months ended March 31, 2021. This increase was primarily attributable to a $0.7 million increase in professional fees associated with an increase of legal and accounting activity in connection with the March 2022 Offering and the At-the-Market Offering facility, and increased recruiting fees for newly hired employees and directors, a $0.4 million increase in salaries and benefits which resulted from new hires, a $0.1 million

Our financial statements do not include adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. Our ability to continue as a going concern depends on our ability to raise additional capital through the sale of equity or debt securities to support our future operations. Our operating needs include the planned costs to operate our business, including amounts required to fund research and development activities including clinical studies, working capital and capital expenditures. Our future capital requirements and the adequacy of our available funds will depend on many factors, including our ability to successfully commercialize our products and services, competing technological and market developments, and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings.
