Opthea Business Snapshot Opthea Ltd Public company listed on ASX (ASX:OPT; Nasdaq:OPT) developing sozinibercept (OPT-302) for wet Age-related Macular Degeneration (“AMD”) Sozinibercept has the potential to be the first product in more than 15 years to improve visual outcomes for wet AMD patients Market capitalization prior to capital raise of approximately A$338M on 31 May 2024 and cash on hand of US$102M at 31 March 2024  (unaudited) Sozinibercept has a novel mechanism of action Sozinibercept is a ‘Trap’ inhibitor of VEGF-C and VEGF-D designed specifically for the eye Sozinibercept is intended for administration in combination with standard of care anti-VEGF-A therapies Large commercial potential and limited competition  Current and growing market opportunity estimated at ~US$15B worldwide for wet AMD Sozinibercept is being developed for use in combination with any of the existing anti-VEGF-A agents, biosimilars, or novel therapies in development for wAMD Innovative approach seeking to provide additional visual acuity benefit over standard of care Potential future extension to Diabetic Macular Edema (“DME”), and co-formulation with a VEGF-A inhibitor Positive endpoints in Phase 2b trial in wet AMD basis for Phase 3 Pivotal Program Sozinibercept combination therapy demonstrated superiority in visual acuity over ranibizumab (Lucentis®) alone at week 24 in a global, randomized, controlled, double-masked trial with 366 subjects. Secondary endpoint results also supportive of primary outcome Pre-specified sub-group analyses suggest greater activity of sozinibercept in lesion-types considered more difficult to treat with anti-VEGF-A  therapy and highest unmet need, which represent approximately 75% of the wet AMD population Two global pivotal phase 3 trials underway and fully enrolled: COAST (n=998) and ShORe (n=986) Phase 3 top-line data for 52-week safety and efficacy results expected for COAST (anticipated in early 2Q CY 2025) and ShORe (anticipated in mid-CY2025) with the pre-specified subgroup as first primary endpoint Hierarchical primary analysis first conducted in the occult and minimally classic population (RAP absent), followed by total patient population Intellectual  property  covering Sozinibercpet to 2034 and beyond Granted patents in the USA (2), Europe (validated in all countries), Australia, Brazil, Canada, China, Columbia, Indonesia, Israel, India, Japan, Korea, Mexico, Malaysia (2), New Zealand, Russia, Singapore & South Africa Divisional applications pending in Europe & USA. Application allowed in Philippines Potential for patent term extensions. In addition, data and market exclusivity of 12 years for biologic in the US after FDA approval  6


Slide 7

Opthea Update Development  Funding  Agreement  (“DFA”) with  Carlyle/Abingworth Signed in August 2022 and amended in December 2023 and fully drawn for a total funding of US$170 million Provided non-equity funding for the development of sozinibercept for wet AMD Amounts repaid capped at 4x following receipt of regulatory approval in the United States or EU No amounts owed if the clinical trials do not meet the primary endpoint or if regulatory approval is not received. In certain circumstances, upon or following the termination of the DFA, the Company may owe the DFA investors a multiple of amounts paid to the Company under the DFA.  Please refer to the description of the DFA included in the Company’s Form 6-K filed with the SEC on August 15, 2022 and the DFA filed as Exhibit 4.14 to the Company’s Annual Report on Form 20-F filed with the SEC on September 29, 2022 for more information. Repayment split between fixed payments (with first payment at approval and 6 annual payments) and variable payments at 7% of net revenues Cash runway (pro forma)(1) Net proceeds from the Offer of US$138.3 million, along with existing cash balance of US$101.6 million at March 31, 2024 (unaudited), are expected to fund the company into Q3 CY 2025, through the anticipated top-line data readout mentioned immediately below, assuming expenses, primarily clinical and CMC related, meet current estimates Announcement of top-line data for COAST (anticipated in early 2Q CY 2025) and ShORe (anticipated in mid-CY2025) trials is expected within the cash runway timelines Preliminary unaudited estimated cash used in operations for FY 2024 between US$170 - $180 million reflects completion of enrollment for the COAST and ShORe trials in February 2024 and May 2024, respectively, assuming expenses, primarily clinical and CMC related, meet current estimates. Clinical trials update and timelines  Global pivotal Phase 3 clinical trials are fully enrolled: COAST enrollment completed in February 2024 with 998 patients ShORe enrollment completed in May 2024 with 986 patients Top-line data (TLD) announcement is expected after patients complete 52-week treatment period, which is anticipated to be for COAST in early 2Q CY 2025 and for ShORe in mid-CY2025 Global phase 3 program primary endpoint is based on the subgroup, representing ~75% of wet AMD patients that demonstrated the highest statistically significant benefit of +5.7 letter change in BCVA(2) from baseline at 24 weeks, potentially increasing the probability of Phase 3 success  With Fast Track Designation, and assuming positive TLD, Opthea can potentially submit a rolling BLA filing which accelerates potential US FDA approval. Sozinibercept safety update Safety data from our completed trials show sozinibercept combination therapy has a safety and tolerability profile comparable to standard of care anti-VEGF-A  monotherapy Note (1): See Risk Factors starting on slide 45 for a discussion of factors that may cause us to require additional funding earlier than expected, including additional delays in completing our phase 3 clinical trials or higher than expected CRO expenses and related costs to run such trials, increases in CMC costs, BLA preparation expenses, and increases in corporate costs (2): Best Corrected Visual Acuity 7

Upon allotment of the Retail Entitlement Offer and subject to satisfying spread requirements set out in ASX Listing Rule 2.5, condition 6, the New Options are intended to be quoted on the ASX. Offer Price The Equity Raising will be conducted at A$0.40 per New Share representing a: 17.5% discount to the last traded price of $0.4852 33.9% discount to the 30 day VWAP price of $0.6053 10.3% discount to TERP of A$0.4464 Use of Proceeds To continue advancing the clinical development of sozinibercept for the  treatment of wet AMD, including to progress the Phase 3 clinical program, CMC (chemistry, manufacturing, and controls) activities, Biologics License Application (BLA) preparations, and for general corporate purposes.

Sozinibercept, a Proprietary VEGF-C/D “Trap” Inhibitor, Has the Potential to Address the Limitations of Anti-VEGF-A Therapies The Problem The Solution Wet AMD is a multi-factorial disease. Treatment with VEGF-A inhibitors upregulates VEGF-C/D, driving angiogenesis and vascular permeability. When used in combination with any VEGF-A inhibitor, OPT-302 completely blocks VEGFR-2 and VEGFR-3 signaling. 1 Faricimab also has inhibitory effect on Ang-2. a Bevacizumab is used ’off-label’ for the treatment of neovascular (wet) AMD Faricimab (Vabysmo®)1

Key Risks 48 Future capital requirements Opthea’s activities will require substantial expenditures. Opthea’s losses from operations, including from clinical trial activities, and negative cash flows, raise substantial doubt about the ability for Opthea to continue as a going concern without additional capital raising activities (for further detail, see “Going concern” risk below). While Opthea expects that the proceeds of the Offer, together with Opthea’s current cash and cash equivalents, will provide funding to progress the activities set out in this presentation into Q3 CY 2025 (assuming expenses, primarily clinical and CMC related, meet current estimates), such proceeds will not be sufficient to fully fund all anticipated costs of the Phase 3 clinical trials and Opthea will require additional funding to reach commercialization of sozinibercept in any indication, including wet AMD. In addition, Opthea will require additional external funding to meet the minimum cash condition under the DFA, including prior to the readout of top-line results for Opthea’s Phase 3 clinical trials for sozinibercept. Further, Opthea’s forecast of its cash runway, following receipt of the proceeds from the Offer, is subject to a number of assumptions, including the timing of Opthea’s top-line data for its Phase 3 clinical trial, as well as assumptions and forecasts regarding Opthea’s Clinical Research Organization (“CRO”), contract manufacturer and labor costs, costs to retain and attract any required personnel and costs to engage additional consultants and advisors. CRO, contract manufacturer and related costs for the Phase 3 clinical trials have also significantly fluctuated from estimates in the past, including due to factors outside Opthea’s control, and efforts to mitigate issues relating to CRO and contract manufacturer activities and other factors described above have resulted, and may continue to result, in higher than expected costs and cash outflows, particularly with respect to CRO and contract manufacturer activities. If these or any additional factors cause the Phase 3 clinical trials to be further delayed or more costly or result in additional operational costs, then Opthea will need to obtain additional capital earlier than the readout of top-line data (which is anticipated for COAST in early 2Q CY 2025 and for ShORe in mid-CY2025). In addition, if Opthea is unable to complete the Offer as contemplated in this presentation, then Opthea will need to seek additional capital from other sources, which may not be available on a timely basis or at all. In such case, Opthea could be forced to delay, limit or terminate its operations, liquidate all or a portion of its assets and/or seek insolvency protection in the near term. Opthea’s failure to raise capital, if and when needed, could delay or suspend Opthea’s business strategy and could have a material adverse effect on Opthea’s activities. If additional funds are raised by issuing equity, this may result in additional dilution to the Shareholders. The pricing of future security issues will also depend on the results of Opthea's scientific research and clinical projects, market factors, demand for securities and the need for capital. If Opthea is unable to secure funding in the short term, there is a risk that Opthea will not be able to continue operating. This section outlines some of the key risks associated with an investment in Opthea, together with the risks relating to participation in the Offer. Some can be mitigated by the use of safeguards and appropriate systems and controls, but some are outside the control of Opthea and cannot be mitigated. These risks should be read in conjunction with the Risk Factors included in Opthea’s 20-F filing for the fiscal year ending 30 June 2023 as filed with the Securities and Exchange Commission on 29 September 2023 and Opthea’s 2024 Half Year Report included as an exhibit to the Form 6-K filed with the SEC on 29 February 2024. Opthea’s business is subject to a number of risk factors both specific to its business and of a general nature which may impact on its future performance and forecasts. This is not an exhaustive list of the relevant risks and the risks set out below are not presented in order of importance. The risks set out below and other risks not specifically referred to may in the future materially adversely affect the value of Opthea shares and ADSs and their performance. Accordingly, no assurance or guarantee of future performance or profitability is given by Opthea in respect of Opthea shares and ADSs. Before subscribing for Opthea shares and ADSs, prospective investors should carefully consider and evaluate Opthea and its business and whether Opthea shares and ADSs are suitable to acquire having regard to their own investment objectives and financial circumstances and taking into consideration the material risk factors, as set out below. The risk factors set out below are not exhaustive, and many of them are outside the control of Opthea and its directors. In deciding whether to participate in the Offer, you should read this presentation in its entirety and carefully consider the risks outlined in this section. Prospective investors should also consider publicly available information on Opthea, examine the full content of this presentation and consult their financial, tax and other professional advisers before making an investment decision. Business Risks


Slide 46

Going concern For the half year ended 31 December 2023, Opthea incurred a loss after income tax of US$  96.2 million and had net cash outflows from operating activities of $69.4 million. At 31 December 2023, Opthea had cash and cash equivalents of US$157.1 million and was in a net liability position of US$46.9 million. At 31 March 2024, Opthea had cash and cash equivalents of US$101.6 million. As Opthea is still in the research and development phase, its ability to continue its development activities as a going concern is dependent upon its ability to raise sufficient capital. Opthea does not have any other committed external sources of funds and expects to fund future cash needs through this Offer, additional capital raising activities or collaborations within the US and Australian markets to leverage greater market exposure and to commercialize sozinibercept. Opthea will need to raise additional funds or reduce expenditures to continue as a Going concern. Based on that, a material uncertainty exists which may cast significant doubt as to whether Opthea will continue as a going concern. If Opthea is unable to continue as a going concern Opthea’s investors may suffer a total loss of their investment. Underwriting risk Opthea has entered into an underwriting agreement with MST Financial Services Pty Ltd (“Underwriter”). The Underwriter has agreed to act as placement agent in relation to the Placement, lead manager and bookrunner in relation to the Entitlement Offer and underwriter in relation to a portion of the Entitlement Offer, subject to certain terms and conditions. Details of the fees payable to the Underwriter are included in the Appendix 3B released to ASX on the date of this presentation. If certain customary conditions are not satisfied or certain customary termination events occur, then the Underwriter may terminate the underwriting agreement. Termination of the underwriting agreement will also effectively terminate any subunderwriting arrangements then in place between the underwriter and any subunderwriters. A summary of the underwriting agreement including events which may trigger termination of the underwriting agreement is set out in “Summary of underwriting agreement” below. If the underwriting agreement is terminated by the Underwriter, Opthea would need to find alternative financing to meet its future funding requirements. There is no guarantee that alternative funding could be sourced, either at all or on satisfactory terms and conditions. See also the ‘Future capital requirements’ disclosure above. Termination of the underwriting agreement could materially adversely affect Opthea’s business, cash flow, financial condition and results of operations. It should also be noted that the Entitlement Offer is only partially underwritten and the Placement is not underwritten. Accordingly, the amount that will be raised under the Offer is uncertain and as such could be insufficient to fund all anticipated costs of the Phase 3 clinical trials to top-line data (anticipated for COAST in early 2Q CY 2025 and for ShORe in mid-CY2025). See “Future capital requirements” risk noted above. Development Funding Agreement The DFA, which amounts to US$170 million (see below for further details), contains several terms that require compliance by the company in conduct of the study including the governance by a Joint Steering Committee (“JSC”) for changes in the original protocols, study design or timelines. Certain modifications require JSC approval and it will be difficult for the company to make modifications on their own. The DFA also contains terms that require Opthea to maintain a minimum cash and cash equivalents balance of US$60 million, or the Minimum Amount, and to provide notice to Ocelot (the SPV established by Carlyle and Abingworth for the purposes of providing funding to Opthea) and the co-investor of Carlyle and Abingworth if Opthea’s cash and cash equivalents balance drops below US$50 million. Following such notice Opthea needs to use its best efforts to commence a public offering or private placement to make up the shortfall of the Minimum Amount and if Opthea is unable to consummate such financing each investor has the right, but not the obligation to increase funding under the DFA to make up for such shortfall. The termination provisions in the DFA on the part of Ocelot and the co-investor are extensive and give Ocelot and the co-investor a wide range of conditions to terminate the agreement. In the event of termination, unless mutual or for breach by Ocelot or the co-investor, amounts owed by Opthea will be multiples of the invested capital to date. As of 31 December 2023, Ocelot has invested US$120 million, and the co-investor has invested US$50 million. Key Risks – Business Risks (cont’d)


Slide 47

Access to capital The Opthea business model requires ongoing re-investment into clinical trials with no revenues currently contracted. As such, Opthea will continue to rely upon cash, raised through equity or debt, on acceptable terms, to fund the business as an on-going concern, including in respect of its Phase 3 clinical trials. However, the DFA limits the type of financing Opthea may pursue in the future and Opthea may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favourable terms, or at all. Any unforeseen events which restrict the ability of Opthea to access capital is likely to affect Opthea’s ability to continue operating. Clinical development Clinical trials are inherently risky, and may prove unsuccessful or non-efficacious, impracticable or costly, which may impact profitability and commercial potential. Operating our clinical trials can be impacted by in part by supply chain issues, global and regional inflation, national and local recessions, hiring qualified staff at sites, Opthea’s CRO and distribution locations, local regulatory approvals, importation and custom requirements and administrative delays. Failure, or negative or inconclusive results, missing data or data quality issues, can occur at many stages in development, and the results of earlier clinical trials are not necessarily predictive of future results and data from clinical trials to date may not be indicative of results obtained when these trials are completed or in later - stage trials. A clinical trial may fail to meet its primary or secondary endpoints and as a result inhibit product development, prevent regulatory requirements being met for marketing approval and restrict successful commercialisation. In addition, data obtained from trials is susceptible to varying interpretations, and regulators may not interpret the data as favourably as Opthea, which may delay, limit or prevent regulatory approval. Sozinibercept may fail to demonstrate a safety profile or sufficient evidence of therapeutic efficacy in future clinical studies to support its ongoing clinical development. In addition, the ability to recruit DME, or other types, of patients into future clinical studies, or secure clinical locations in which to conduct those studies, may not occur at a sufficient rate to maintain future program timelines. Clinical data Opthea maintains sensitive clinical data. Opthea or systems used by Opthea may be subject to a cyber security attack or data breaches by employees or external parties with either permitted or unauthorized access. There is therefore a risk that sensitive data may be exposed to the public or be permanently lost. A cyber security attack or data breach may also have implications for Opthea’s obligations under any relevant data protection or privacy legislation. Failure to comply with such legislation or regulations can result in penalties, negative publicity and damage to its brand and reputation. Research and development activities Opthea’s future success is dependent on the performance of sozinibercept in clinical trials and whether it proves to be a safe and effective treatment. Sozinibercept is an experimental product in clinical development and product commercialisation resulting in potential product sales and revenues is not likely to occur until some time in the future  , if ever, and there is no guarantee that it will be successful. Sozinibercept requires additional research and development, including ongoing clinical evaluation of safety and efficacy in clinical trials and regulatory approval prior to marketing authorisation. Drug development is associated with a high failure rate and until Opthea is able to provide further clinical evidence of sozinibercept’s ability to improve outcomes in patients with eye disease, the future success of the product developed remains speculative. Research and development risks include uncertainty of the outcome of results, difficulties or delays in development and general uncertainty around the scientific development of novel pharmaceutical products and any of these risks, if they were to materialize, could impact Opthea’s progress and could have a material adverse effect on Opthea’s future financial performance. Key Risks – Business Risks (cont’d)


Slide 48

50 Regulatory approval   Opthea operates within a highly regulated industry, relating to the manufacture, distribution and supply of pharmaceutical products. There is no guarantee that Opthea will obtain or maintain the required approvals, licenses and registrations from all relevant regulatory authorities in all jurisdictions in which it operates. Further clinical trials may be delayed and Opthea may incur further costs if the Food and Drug Administration (FDA) and other regulatory agencies observe deficiencies that require resolution or request additional studies be conducted in addition to those that are currently planned. Furthermore, Opthea is exposed to the risk of changes to existing, or the introduction of new, government policies, regulations and legislation in all jurisdictions in which it operates. A failure to obtain or maintain any required approvals, licenses and registrations or any change in regulation may adversely affect Opthea’s ability to commercialise and manufacture its treatments. Competition The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change in Australia, the United States and elsewhere, and there are no guarantees about Opthea’s ability to successfully compete. Opthea's products may compete with existing alternative treatments that are already available to customers. In addition, a number of companies, both in Australia and internationally, are pursuing the development of products that target wet AMD and DME. Some of these companies may have, or may develop, technologies superior to Opthea’s own technology. Some competitors of Opthea may have substantially greater financial, technical and human resources than Opthea does, as well as broader product offerings and greater market and brand presence. Opthea’s services, expertise or products may be rendered obsolete or uneconomical or decrease in attractiveness or value by advances or entirely different approaches developed by either Opthea or its competitors. Intellectual property Securing rights in technology and patents is an integral part of securing potential product value in the outcomes of biotechnology research and development. Competition in retaining and sustaining protection of technology and the complex nature of technologies can lead to patent disputes. Opthea’s success depends, in part, on its ability to obtain patents, maintain trade secret protection and operate without infringing the proprietary rights of third parties. Because the patent position of biotechnology companies can be highly uncertain and frequently involves complex legal and factual questions, neither the breadth of claims allowed in biotechnology patents nor their enforceability can be predicted. There can be no assurance that any patents which Opthea may own, access or control will afford Opthea commercially significant protection of its technology or its products, have commercial application, or that access to these patents will mean that Opthea will be free to commercialize its drug candidates. The granting of a patent does not guarantee that the rights of others are not infringed or that competitors will not develop technology or products to avoid Opthea's patented technology. Patenting strategies do not cover all countries which may lead to generic competition arising in those markets. Manufacturing Scale-up of sozinibercept manufacture to support potential commercialization of sozinibercept. Process performance qualification or “PPQ” will need to be completed as part of the filing for marketing approval. As such, there is a risk that the PPQ may present technical difficulties. Technical difficulties could include the inability to generate material that meets regulatory specifications for human administration, the product yield from manufacturing batches may be insufficient to conduct the clinical studies and support commercialization as currently planned and there could be inconsistency in batch production such that batches do not meet commercial specifications due to deviations from the process during manufacture. Any unforeseen difficulties relating to manufacturing, including changes in methods of product candidate manufacturing or formulation, disruption to supply, shortages of raw materials or changes to arrangements with, or capacity of, any third-party manufacturers, may negatively impact Opthea’s ability to generate revenue in the future. Key Risks – Business Risks (cont’d)


Slide 49

51 Commercialization Sozinibercept has not been approved for commercial sale, and Opthea does not expect commercial sales to occur until some time in the future, if ever. If sozinibercept is approved for commercial sale, Opthea’s commercialization expenses will increase significantly as it establishes sales, marketing, distribution, manufacturing, supply chain and other commercial infrastructure. In addition, sozinibercept may not achieve adequate market acceptance among physicians, patients, healthcare payors and others in the medical community necessary for commercial success. In addition, sozinibercept may become subject to unfavourable pricing regulation, third party reimbursement practices or healthcare reform initiatives which could impact ability to achieve profitability. Health Epidemics Opthea’s business was and may in the future be negatively affected by the effects of health epidemics in regions where Opthea or third parties on which Opthea relies have significant manufacturing facilities, concentrations of clinical trial sites or other business operations. Health epidemics in regions where Opthea has concentrations of clinical trial sites or other business operations could negatively affect its business, including by causing significant disruption in the operations of third-party manufacturers and CROs upon whom Opthea relies (for example, Covid-19 negatively impacted Opthea’s ability to initiate clinical trial sites, maintain patient enrollment and enroll new patients). Reliance on Third Parties, including Agents, Suppliers, Distributors, Contractors and Joint Venture Partners Opthea may engage with various third parties to assist with different stages of the research and development and manufacturing process, including agents, suppliers, distributors and contractors, and there is no guarantee that these third parties will comply with their respective contractual obligations. Transition of certain of these third parties could cause delay or disruption in the clinical trials or manufacturing. This could adversely impact Opthea’s progress and cause delays in or impede research or production, or result in cost increases. Opthea is unable to predict the risk of financial failure or default by a participant in any joint venture to which Opthea may become a party or the insolvency or managerial failure by any of the contractors used by Opthea in any of its activities or the insolvency or other managerial failure by any of the other service providers used by Opthea for any activity. Reliance on key personnel Opthea is reliant on key personnel it employs or engages. Loss of such personnel may have a material adverse impact on the performance of Opthea. In addition, recruiting qualified personnel is critical to Opthea’s success. This includes attracting and retaining staff with sufficient skills to develop intellectual property. As Opthea’s business grows and progresses through Phase 3 development, it will require additional key staff in clinical development, commercial, and administrative functions. There can be no assurance that Opthea will be successful in attracting and retaining qualified personnel. The loss of key personnel or the inability to attract suitably qualified additional personnel could have a material adverse effect on Opthea’s financial performance. Commercial risk Opthea may, from time to time, consider acquisition, licensing, partnership or other corporate opportunities for Opthea’s development programs. There can be no assurance that any such acquisition, licensing, partnership or corporate opportunities can be concluded on terms that are, or are believed by Opthea to be, commercially acceptable. In the case of licensing and partnership opportunities, even if such terms are agreed there is a risk that the performance of distributors and the delivery of contracted outcomes by collaborators will not occur due to a range of unforeseen factors relating to environment, technology and market conditions. Future success will also depend on Opthea’s ability to achieve market acceptance and attract and retain customers, which includes convincing potential consumers and partners of the efficacy of Opthea’s products and Opthea’s ability to manufacture a sufficient quantity and quality of products at a satisfactory price. Key Risks – Business Risks (cont’d)


Slide 50

Information technology Opthea relies on effective information technology, software, data centres and communication systems. There is a risk that these systems may be adversely affected by disruption, failure, service outages or data corruption that could occur as a result of computer viruses, “bugs” or “worms”, malware, internal or external misuse by websites, cyber-attacks or other disruptions including natural disasters, power outages or other similar events. Opthea may be significantly impacted by disruption to any of these systems or platforms. Insurance and uninsured risks Although Opthea maintains insurance to protect against certain risks in such amounts as it considers to be reasonable, its insurance will not cover all the potential risks associated with its operations and insurance coverage may not continue to be available, commercially acceptable, or may not be adequate to cover any resulting liability. It is not always possible to obtain insurance against all such risks and Opthea may decide not to insure against certain risks because of high premiums or other reasons. Product safety and efficacy Serious or unexpected health, safety or efficacy concerns with products may expose Opthea to reputational harm or reduced market acceptance of its products, and may lead to product recalls and/or product liability claims and resulting liability, and increased regulatory reporting. There can be no guarantee that unforeseen adverse events or manufacturing defects will not occur. Opthea may seek to obtain product liability insurance at the appropriate time in order to seek to minimise its liability to such claims, however there can be no assurance that adequate insurance coverage will be available at an acceptable cost. Any health, safety or efficacy concerns are likely to lead to reduced customer demand and impact on the potential future profitability of Opthea. Litigation In the ordinary course of conducting its business, Opthea is exposed to potential litigation and other proceedings, including through claims of breach of agreements, intellectual property infringement or in relation to employees (through personal injuries, occupational health and safety or otherwise). If such proceedings were brought against Opthea, it could incur considerable defence costs (even if successful), with the potential for damages and costs awards against Opthea if it were unsuccessful, which could have a significant adverse financial impact on Opthea’s business. Changes in laws can heighten litigation risk (for example, antitrust and intellectual property). Circumstances may also arise in which Opthea, having received legal advice, considers that it is reasonable or necessary to initiate litigation or other proceedings, including for example to protect its intellectual property rights. There has been substantial litigation and other proceedings in the pharmaceutical industry, including class actions from purchasers and end users of pharmaceutical products.

Slide 51

Offer and General Risks Key Risks – Offer and General Risks Effects of Offer on control Regal has informed the Company that its current voting power in the Company is 23.56% (constituted by holdings of 132,902,835 ordinary shares and 2,907,403 ADSs). Regal will have a pro rata entitlement under the Entitlement Offer of 108,936,750. Regal has also entered into a sub-underwriting arrangement with the Underwriter under which it will sub-underwrite : the subscription of up to 137,607,736 shares under the Retail Entitlement Offer; and the subscription of up to 75,000,000 shares under the Institutional Entitlement Offer. Through its participation in the Entitlement Offer, and any subscription of New Shares as a sub-underwriter of the Entitlement Offer, it is likely that the voting power of Regal will increase. It is not possible to determine at this stage the extent of that increase, and Regal will need to comply with the provisions of Chapter 6 of the Corporations Act. The potential effect that the issue of the New Shares will have on the control of the Company, and the consequences of that effect, will depend on a number of factors, including: the extent to which Eligible Shareholders other than Regal take up their Entitlements; the extent to which Eligible Retail Shareholders participate in the Top-Up Facility; the number of New Shares placed to institutional and/or sophisticated investors under the Institutional Shortfall Bookbuild and the Placement; and the extent to which any other investors or existing Eligible Shareholders agree to sub-underwrite the Entitlement Offer. Share price fluctuations The market price and trading volume of Opthea ordinary shares and ADSs may fluctuate due to various economic factors, many of which are non-specific to Opthea and beyond the control of the Company, including, but not limited to Australian and international general economic conditions, inflation rates, interest rates, changes in government, fiscal, monetary and regulatory policies, global geo-political events and hostilities and acts of terrorism, and investor perceptions. The trading volume of ordinary shares and ADSs may fluctuate and cause significant price variations to occur. Fluctuations such as these may adversely affect the market price of Opthea ordinary shares and ADSs. Neither Opthea nor the directors warrant the future performance of Opthea or any return on investment in Opthea.  Specific factors that could negatively affect the price of ordinary shares and ADSs or result in fluctuations in their price and trading volume include: actual or anticipated fluctuations in our financial condition and operating results; actual or anticipated changes in our growth rate relative to our competitors; competition from existing products or new products that may emerge; announcements by us or our competitors of significant acquisitions, divestitures, spin-offs, strategic partnerships, joint ventures, collaborations, capital commitments or changes in business strategy; adverse results or delays in our or any of our competitors’ preclinical studies or clinical trials;


Slide 52

Offer and General Risks Key Risks – Offer and General Risks Share price fluctuations (continued) adverse regulatory decisions, including failure to receive regulatory approval for any of our product candidates; the termination of a strategic alliance or the inability to establish additional strategic alliances; failure to meet or exceed financial estimates and projections of the investment community or that we provide to the public; issuance of new or updated research or reports by securities analysts; fluctuations in the valuation of companies perceived by investors to be comparable to us; changes in trading volume and price of ADSs on the Nasdaq and of ordinary shares on the ASX; additions or departures of key management or scientific personnel; disruptions in our supply or manufacturing arrangements; disputes or other developments related to proprietary rights, including patents, litigation matters and our ability to obtain patent and other intellectual property protection for our technologies; changes to coverage policies or reimbursement levels by commercial third-party payors and government payors and any announcements relating to coverage policies or reimbursement levels; litigation involving Opthea; announcement or expectation of additional debt or equity financing efforts; natural disasters or other calamities or disease outbreaks; sales of ADSs by the Company, its affiliates or its other shareholders; and general economic and market conditions.


Slide 53

53 New Options Opthea has applied or will apply for quotation of the New Options within seven days of the Prospectus being lodged with ASIC. ASX requires Opthea to meet certain conditions for quotation of New Options as a new class on ASX. There is a risk that Opthea may not be able to meet those requirements. The fact that ASX may agree to grant official quotation of the New Options is not to be taken in any way as an indication of the merits of Opthea or its securities. If Opthea’s application for the New Options to be quoted on ASX is granted, the trading price of the New Options may be affected by the ongoing performance, financial position, and solvency of Opthea. Should the ASX grant official quotation of the New Options, the liquidity of trading in New Options on the ASX may be limited at times and may affect an eligible participant’s ability to buy or sell New Options. In addition, Opthea’s share price may not exceed the exercise price of the New Options during the exercise period. In such circumstances the New Options lapse without any value being realised. Dilution risk Investors who do not participate in the Offer, or do not take up all of their entitlement under the Entitlement Offer, will have their percentage security holding in Opthea diluted (in addition to the dilution resulting from the Placement). In addition, Opthea’s need to raise additional capital in the future in order to meet its operating or financing requirements, including by way of additional borrowings may change over time. Future equity raisings or equity funded acquisitions may dilute the holdings of particular shareholders to the extent that such shareholders do not subscribe for additional equity, or are otherwise not invited to subscribe for additional equity. Risks related to ownership of the ADSs The rights of our shareholders may be different from the rights of shareholders in companies governed by the laws of U.S. jurisdictions. As a foreign private issuer and as permitted by the listing requirements of Nasdaq, we will rely on certain home country corporate governance practices rather than the corporate governance requirements of Nasdaq. We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses. Both foreign private issuers and emerging growth companies are also exempt from certain more stringent executive compensation disclosure rules for U.S. public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Even if we no longer qualify as an emerging growth company, so long as we remain a foreign private issuer, we will continue to be exempt from such compensation disclosures. The following risks are also relevant in relation to the ownership of ADSs: ADS holders may be subject to additional risks related to holding ADSs rather than ordinary shares; We do not currently intend to pay dividends on our securities and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of the ADSs; If the Company becomes classified as a passive foreign investment company, the Company’s U.S. security holders may suffer adverse tax consequences; and U.S. investors may have difficulty enforcing civil liabilities against the Company and its directors. Key Risks – Offer and General Risks (cont’d)


Slide 54

Economic risks Opthea is exposed to economic factors in the ordinary course of business. A number of economic factors and conditions, both Australian and global, affect the performance of financial markets generally, which could affect the price at which Opthea shares and ADSs trade on ASX and Nasdaq, respectively. Among other things, adverse changes in macroeconomic conditions, including movements on international and domestic stock markets, interest rates, exchange rates, cost and availability of credit, general consumption and consumer spending, input costs, employment rates and industrial disruptions, inflation and inflationary expectations and overall economic conditions, economic cycles, trade tariffs and restrictions, investor sentiment, political events and levels of economic growth, both domestically and internationally, as well as government taxation, fiscal, monetary, regulatory and other policy changes may affect the demand for, and price of, Opthea shares and ADSs and adversely impact Opthea’s business, financial position and operating results. Trading prices can be volatile and volatility can be caused by general market risks such as those that have been mentioned. New Shares and New ADSs in Opthea may trade at or below the price at which they commence trading on ASX including as a result of any of the factors that have been mentioned, and factors such as those mentioned may also affect the income, expenses and liquidity of Opthea. Additionally, the stock market can experience price and volume fluctuations that may be unrelated or disproportionate to the operating performance of Opthea. Cost inflation Higher than expected inflation rates generally, or specific to the biotechnology and pharmaceuticals industry in particular, could be expected to increase operating and development costs and potentially reduce the value of future project developments. While, in some cases, such cost increases might be offset by increased selling prices, there is no assurance that this would be possible or that Opthea will be in its production and supply phase of its business when this occurs. Taxation Future changes in Australian taxation law, including changes in interpretation or application of the law by the courts or taxation authorities in Australia, may affect taxation treatment of an investment in Opthea shares and ADSs, or the holding and disposal of those shares. Further, changes in tax law, or changes in the way tax law is expected to be interpreted, in the various jurisdictions in which Opthea operates, may impact the future tax liabilities of Opthea. Opthea projects that it will receive cash refunds under the Research and Development Tax Incentive scheme (the “Scheme and R&D Tax Credits”) to offset the costs of its clinical programs and other qualifying expenditure, incurred both in Australia and overseas. The assumptions underlying Opthea’s projected Scheme and R&D Tax Credits are based on actual amounts received for the 2023 financial year as a proportion of qualifying expenditure under the scheme. The Commonwealth Government and/or the Australian Taxation Office could change the rules of the regulatory regime with the effect that future amounts paid to Opthea as a proportion of its expenses could be materially lower than assumed in the Company’s projections. Any rule changes made that materially reduce the amount Opthea was able to claim for the current scheme would have a material effect on the cash flows of the Company. Opthea believes that it is not a passive foreign investment company (PFIC) for U.S. federal income tax purposes for its current taxable year and it expects that it will likely not be a PFIC in the foreseeable future, although there can be no assurance in this regard and this determination  depends on legal and factual considerations that cannot be predicted. If the Company becomes classified as a passive foreign investment company, the Company’s U.S. security holders may suffer adverse tax consequences. Accounting standards Opthea prepares its general purpose financial statements in accordance with Australian International Financial Reporting Standards (AIFRS) and the Corporations Act, which may differ significantly from the accounting standards applied by other companies (such as U.S. GAAP). Australian Accounting Standards are subject to amendment from time to time, and any such changes may impact on Opthea's statement of financial position or statement of financial performance.

Forward-looking statements There can be no guarantee that the assumptions and contingencies on which the forward-looking statements, opinions and estimates are based will ultimately prove to be valid or accurate. The forward-looking statements, opinions and estimates included in this presentation depend on various factors, including known and unknown risks, many of which are outside the control of Opthea. Actual performance of Opthea may materially differ from expected performance. Dividends No assurances can be given in relation to the payment of future dividends. Future determinations as to the payment of dividends by Opthea will be at the discretion of Opthea and will depend upon the availability of profits, the operating results and financial conditions of Opthea, future capital requirements, covenants in relevant financing agreements, general business and financial conditions and other factors considered relevant by Opthea. No assurance can be given in relation to the level of tax deferral of future dividends. Tax deferred capacity will depend upon the amount of capital allowances available and other factors. Changes in applicable law and regulations Opthea will be subject to changes in laws, regulations and government policy which may affect its operations and/or financial performance. Such changes may impact Opthea’s income or operational expenditure. Opthea is also subject to changes in taxation regimes and Accounting Standards. There can be no assurance that such changes will not have a material adverse effect on Opthea’s business, operational performance or financial results or returns to shareholders. As noted above under “Taxation”, adverse changes to tax law may also reduce Opthea’s capacity to claim research and incentive grants or rebates, thereby increasing expenses and reducing Opthea’s assets.
