Immutep Ltd (PRRUF) Risk Analysis

The market price of our ordinary shares and ADSs historically has been, and we expect will continue to be, subject to significant fluctuations over short periods of time. These fluctuations may be due to factors specific to us, to changes in analysts' recommendations and valuations, to arbitrage between our Australian-listed ordinary shares and our NASDAQ-listed ADSs, to changes in exchange rates, or to factors affecting the biopharmaceutical industry or the securities markets in general. Market fluctuations, as well as general political and economic conditions, such as a recession, interest rate or currency fluctuations, could adversely affect the market price of our securities. For example, during the last two fiscal years, the market price for our ordinary shares on the Australian Securities Exchange and ADSs on NASDAQ has ranged from a low of A$0.223 and US$1.320, respectively, to a high of A$0.485 and US$3.335, respectively. We may experience a material decline in the market price of our shares, regardless of our operating performance. Therefore, a holder of our ordinary shares or ADSs may not be able to sell those ordinary shares or ADSs at or above the price paid by such holder for such shares or ADSs. Price declines in our ordinary shares or ADSs could result from a variety of factors, including many outside our control. These factors include: -   the results of pre-clinical testing and clinical trials by us and our competitors;-   unforeseen safety issues or adverse side effects resulting from the clinical trials or the commercial use of our product candidates;-   regulatory actions in respect of any of our products or the products of any of our competitors;-   announcements of the introduction of new products by us or our competitors;-   market conditions, including market conditions in the pharmaceutical and biotechnology sectors;-   increases in our costs or decreases in our revenues due to unfavorable movements in foreign currency exchange rates;-   developments or litigation concerning patents, licenses and other intellectual property rights;-   litigation or public concern about the safety of our potential products;-   changes in recommendations or earnings estimates by securities analysts;-   actual and anticipated fluctuations in our quarterly operating results;-   deviations in our operating results from the estimates of securities analysts;-   rumors relating to us or our competitors;-   additions or departures of key personnel;-   changes in third-party reimbursement policies; and -   developments concerning current or future strategic alliances or acquisitions. In addition, volatility and low market price of our ordinary shares and/or ADSs may adversely impact investors' interest in our securities. A decline in investors' interest may prompt further volatility and decrease in market price.

The SEC has adopted regulations which generally define "penny stock" to be an equity security that has a market price of less than $5.00 per share, subject to specific exemptions. During the fiscal year ended June 30, 2025, our American Depository Shares traded on the NASDAQ from low of US$1.32 to a high of US$2.72 per share. Penny stock rules impose additional sales practice requirements on broker-dealers who sell to persons other than established customers and "accredited investors". The term "accredited investor" refers generally to institutions with assets in excess of US$5,000,000 or individuals with a net worth in excess of US$1,000,000 or annual income exceeding US$200,000 or US$300,000 jointly with their spouse in each of the prior two years. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC, which (a) contains a description of the nature and level of risk in the market for penny stocks in both public offerings and secondary trading; (b) contains a description of the broker's or dealer's duties to the customer and of the rights and remedies available to the customer with respect to a violation of such duties or other requirements of the securities laws; (c) contains a brief, clear, narrative description of a dealer market, including bid and ask prices for penny stocks and the significance of the spread between the bid and ask price;(d) contains a toll-free telephone number for inquiries on disciplinary actions; (e) defines significant terms in the disclosure document or in the conduct of trading in penny stocks; and (f) contains such other information and is in such form, including language, type size and format, as the SEC shall require by rule or regulation. The broker-dealer also must provide, prior to effecting any transaction in a penny stock, the customer with (a) bid and offer quotations for the penny stock; (b) the compensation of the broker-dealer and its salesperson in the transaction; (c) the number of shares to which such bid and ask prices apply, or other comparable information relating to the depth and liquidity of the market for such stock; and (d) a monthly account statement showing the market value of each penny stock held in the customer's account. In addition, the penny stock rules require that prior to a transaction in a penny stock not otherwise exempt from those rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written acknowledgment of the receipt of a risk disclosure statement, a written agreement as to transactions involving penny stocks, and a signed and dated copy of a written suitability statement. These disclosure requirements may significantly burden trading in, and delay the execution of transactions in, our ADSs. Thus, if our ADSs are considered penny stock, these disclosure requirements may adversely impact market trading in our ADSs.

Our ordinary shares are listed and traded on the ASX, NASDAQ and on Over The Counter markets within Germany. Price levels for our ordinary shares could fluctuate significantly on either market, independent of our share price on the other market. Investors could seek to sell or buy our shares to take advantage of any price differences between the three markets through a practice referred to as arbitrage. Any arbitrage activity could create unexpected volatility in our share prices on either exchange or the volumes of shares available for trading on either exchange. In addition, holders of shares in either jurisdiction will not be immediately able to transfer such shares for trading on the other markets without effecting necessary procedures with our transfer agent. This could result in time delays and additional cost for our shareholders. Further, if we are unable to continue to meet the regulatory requirements for listing on the ASX and NASDAQ, we may lose our listing on any of these exchanges, which could impair the liquidity of our shares.

The Bank of New York Mellon, as depositary, registers and delivers our American Depositary Shares, or ADSs. Our ADS holders are not treated as shareholders and do not have the rights of shareholders. The depositary is the holder of the shares underlying our ADSs. Holders of our ADSs have ADS holder rights. A deposit agreement among us, the depositary and our ADS holders, and the beneficial owners of ADSs, sets out ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs. For a description of ADS holder rights, see "Item 12. Description of Securities Other than Equity Securities-D. American Depositary Shares." Our shareholders have shareholder rights. Australian law and our constitution govern shareholder rights. For a description of our shareholders' rights, see "Item 10. Additional Information-B. Memorandum and Articles of Association." Shareholders are entitled to our notices of general meetings and to attend and vote at our general meetings of shareholders. At a general meeting, every shareholder present (in person or by proxy, attorney or representative) and entitled to vote has one vote on a show of hands. Every shareholder present (in person or by proxy, attorney or representative) and entitled to vote has one vote per fully paid ordinary share on a poll. This is subject to any other rights or restrictions which may be attached to any shares. Our ADS holders do not have the same voting rights as our shareholders. ADS holders may exercise voting rights with respect to the underlying ordinary shares only in accordance with the provisions of the deposit agreement. Under the deposit agreement, ADS holders vote by giving voting instructions to the depositary. Upon receipt of instructions, the depositary will try to vote in accordance with those instructions. Otherwise, ADS holders will not be able to vote unless they withdraw the ordinary shares underlying their ADSs. If we ask for our ADS holders' instructions, the depositary will notify our ADS holders of the upcoming vote and arrange to deliver our voting materials and form of notice to them. The depositary will try, as far as practical, subject to Australian law and the provisions of the depositary agreement, to vote the shares as our ADS holders instruct. The depositary will not vote or attempt to exercise the right to vote other than in accordance with the instructions of the ADS holders. We cannot assure our ADS holders that they will learn of ordinary shareholders' meetings and receive the voting materials in time to instruct the depositary or withdraw the underlying ordinary shares. This means that there is a risk that our ADS holders may not be able to exercise voting rights and there may be nothing they can do if their shares are not voted as they requested.

The deposit agreement with the depositary generally requires the depositary to convert foreign currency it receives in respect of deposited securities into U.S. dollars and distribute the U.S. dollars to ADS holders, provided the depositary can do so on a reasonable basis. If it does not convert foreign currency, the depositary may distribute the foreign currency only to those ADS holders to whom it is possible to do so. If a distribution is payable by us in Australian dollars, the depositary will hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid. It will not invest the foreign currency and it will not be liable for any interest. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, our ADS holders may lose some of the value of the distribution. The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. This means that our ADS holders may not receive any distributions we make on our shares or any value for them if it is illegal or impractical for us to make them available.

The ADSs are listed on the Nasdaq Global Market under the symbol "IMMP." In the past we have failed, and in the future we may again fail, to comply with the Nasdaq Global Market regulations and listing requirements as to minimum shareholders' equity, minimum market value, minimum total assets and revenue, minimum bid price, minimum public float and/or other requirements, and as a result Nasdaq may initiate procedures to delist the ADSs from the Nasdaq Global Market, which may adversely affect our business. If we fail to meet Nasdaq's continued listing rules, the ADSs may be delisted from the Nasdaq Global Market. Delisting from the Nasdaq Global Market could have an adverse effect on our business, including our ability to access future capital, and on the trading of the ADSs. If a delisting of the ADSs were to occur, the ADSs may trade in the over-the-counter market such as on the OTC Bulletin Board or on the "pink sheets". The over-the- counter market is generally considered to be a less efficient market, and this could diminish investors' interest in the ADSs as well as significantly impact the price and liquidity of the ADSs. Any such delisting may also adversely affect the trading of the ADSs by ADS holders or impede them from liquidating their holdings. Delisting may also adversely impact the success of future issues of securities or the possibility to receive additional financing, particularly in the United States.

We are a public company incorporated under the laws of Australia. Therefore, the rights of holders of our ordinary shares are governed by Australian law and our Constitution. These rights differ from the typical rights of shareholders in U.S. corporations. The rights of holders of ADSs are affected by Australian law and our Constitution but are governed by U.S. law. Circumstances that under U.S. law may entitle a shareholder in a U.S. company to claim damages may also give rise to a cause of action under Australian law entitling a shareholder in an Australian company to claim damages. However, this will not always be the case. Holders of our ordinary shares or ADSs may have difficulties enforcing, in actions brought in courts in jurisdictions located outside the U.S., liabilities under U.S. securities laws. In particular, if such a holder sought to bring proceedings in Australia based on U.S. securities laws, the Australian court might consider: -   that it did not have jurisdiction; and/or -   that it was not an appropriate forum for such proceedings; and/or -   that, applying Australian conflict of laws rule, U.S. law (including U.S. securities laws) did not apply to the relationship between holders of our ordinary shares or ADSs and us or our directors and officers; and/or -   that the U.S. securities laws were of a public or penal nature and should not be enforced by the Australian court. Holders of our ordinary shares and ADSs may also have difficulties enforcing in courts outside the U.S. judgments obtained in the U.S. courts against any of our directors and executive officers or us, including actions under the civil liability provisions of the U.S. securities laws.
