RECOMMENDED SCHEME OF ARRANGEMENT

of

ACACIA PHARMA GROUP PLC

by

EAGLE PHARMACEUTICALS, INC.

to be effected by means of a Scheme of Arrangement

under Part 26 of the Companies Act 2006

Summary

This summary should be read in conjunction with, and is subject to, the full text of the following announcement (including its Appendices).

Key highlights

• Acacia Pharma Group PLC (“Acacia”) met its formulary goals for both Barhemsys® and Byfavo® in FY2021 and continues to be encouraged that feedback for both products is indicative of significant future commercial potential.
• However, Acacia’s standalone financial condition has been negatively impacted by physical access limitations caused by the global COVID-19 pandemic, and a significant latency of demand due to postponement of surgical procedures. Accordingly, Acacia expects it would require a minimum of approximately US$115m of additional cash to fund operations to break-even (based on projections assuming break-even by early FY2025).
• As a result, the Acacia Board appointed Greenhill to undertake a comprehensive review of strategic alternatives available to maximise value for Acacia Shareholders. The review included consideration of options to raise additional capital, but found that the terms on which such capital was likely to be available would have led to significant dilution and potential destruction of value for Acacia Shareholders.
• Following this comprehensive exploration and assessment of all strategic alternatives, the board of directors of Acacia and the board of directors of Eagle Pharmaceuticals, Inc. (“Eagle”) hereby announce that they have reached agreement on the terms of a transfer of the entire issued and to be issued share capital of Acacia to Eagle by way of a scheme of arrangement under Part 26 of the Companies Act 2006 (the “Proposed Transaction”).
• Under the terms of the Proposed Transaction, each Scheme Shareholder will receive as consideration (the “Consideration”):

for each Scheme Share, €0.68 in cash and 0.0049 New Eagle Shares

• The Proposed Transaction values Acacia’s existing issued and to be issued share capital at approximately €94.7 million on a fully diluted basis.
• The cash portion of the Consideration represents approximately 75 per cent. of the total Consideration, and the New Eagle Shares that Acacia Shareholders would receive represent approximately 25 per cent. of the total Consideration, which represents approximately 3.8 per cent. of the enlarged Eagle share capital in issue immediately following completion of the Scheme. The total Consideration equates to €0.90 for each Scheme Share.
• The Consideration provides Acacia Shareholders with both up-front cash and, through the New Eagle Shares to be acquired by Acacia Shareholders, equity participation in the value creation potential for the enlarged business through de-risked funding requirements, enlarged group synergies, and being part of a well-funded entity with shares trading on a liquid exchange.
• Having considered all of the available alternatives as part of its strategic review, the Acacia Board believes that the Proposed Transaction represents the best option for Acacia Shareholders to maximise the value of their shares, and therefore unanimously recommends the Proposed Transaction. 
• Furthermore, the Acacia Board considers that there is a significant risk that if the Scheme is not approved by the necessary number of Acacia Shareholders, this could lead to a very material reduction in the value attributable to Acacia Shares and/or an insolvency procedure relating to the Acacia Group, which could in turn result in negligible (if any) value being attributable to Acacia Shares.
• In making its recommendation, the board of Acacia has considered the financial position of Acacia given the significant operational challenges as a result of the limited physical access to institutions resulting from the global COVID-19 pandemic, as well as the significant latency of demand due to the postponement of non-essential surgical procedures, as a result of which the Acacia Group has experienced a significant reduction in its available liquidity as the net revenue in 2021 and so far in 2022 continues to lag behind expectations.

Recommendation, irrevocable undertakings and shareholder support for the Proposed Transaction

• The Acacia Directors consider the Proposed Transaction to be the best available option for Acacia Shareholders. In making this assessment, the Acacia Directors have received financial advice from Greenhill who, in providing its financial advice, has taken into account the commercial assessments of the Acacia Directors. Accordingly, the Acacia Directors intend unanimously to recommend that Acacia Shareholders vote in favour of the Scheme at the Court Meeting and the Resolutions to be proposed at the General Meeting, as the Acacia Directors have irrevocably undertaken to do in respect of the 217,543 Acacia Shares which they hold and which they control (or can procure the control of) the voting rights, representing approximately 0.22 per cent. of the issued share capital of Acacia on 25 March 2022, being the last business day before this announcement.
• In addition to the irrevocable undertakings referred to above, Eagle has also received irrevocable undertakings from the three largest shareholders of Acacia to vote in favour of the Scheme at the Court Meeting and the Resolutions to be proposed at the General Meeting in respect of the 49,012,875 Acacia Shares which they hold and which they control (or can procure the control of) the voting rights, representing approximately 48.56 per cent. of the issued share capital of Acacia on 25 March 2022, being the last business day before this announcement.
• Therefore, Eagle has received irrevocable undertakings representing, in aggregate, 49,230,418 Acacia Shares representing approximately 48.78 per cent. of the issued share capital of Acacia.
• Further details of these irrevocable undertakings, including the circumstances in which they cease to be binding, are set out in Appendix 3 to this announcement.

Comments on the Proposed Transaction

• Commenting on the Proposed Transaction, Scott Byrd, Chairman of Acacia, said:

“I am proud of the progress that Acacia has achieved in bringing Barhemsys® through clinical trials to the market and in the progress it has subsequently made in launching both this product and Byfavo® in the US. Both products are designed to address clear and important hospital needs and to date have received positive feedback from customers and strong formulary acceptance, positioning them well for future success. However, the global COVID-19 pandemic has resulted in significant and sustained challenges that have significantly disrupted hospital operations, limited access, and dramatically increased the time and investment required for product launches.

The Acacia Board believes this Proposed Transaction represents an opportunity for Acacia shareholders to realise value for their investment in cash and, through Eagle, retain an interest in the future value that may be generated from Barhemsys® and Byfavo® being part of a larger portfolio of hospital products, in the hands of a well-capitalised company. We are therefore unanimously recommending this Proposed Transaction to our shareholders.”

• Commenting on the Proposed Transaction, Scott Tarriff, President and Chief Executive Officer of Eagle, said:

“We are delighted to announce that we have agreed to terms for the proposed acquisition of Acacia. This will be a very important acquisition for us, both financially and strategically. In recent years, the pharmaceutical industry has witnessed slower uptake of new products and longer ramp periods. In the face of further challenges brought about by the COVID-19 pandemic, many smaller underfunded companies experienced significant hurdles launching products. We therefore believe that Eagle is well suited to drive uptake of these two new products, building from Acacia’s established foundation since its launch, through our experienced and specialised hospital-based sales organisation with minimal additional infrastructure.”

Timetable

• The Proposed Transaction will be implemented by means of a Court-sanctioned scheme of arrangement between Acacia and the Scheme Shareholders under Part 26 of the Companies Act.
• The Scheme Document, containing further information about the Proposed Transaction and notices of the Court Meeting and General Meeting, together with the Forms of Proxy, will be sent to Acacia Shareholders and (for information only) participants in the Acacia Share Schemes as soon as reasonably practicable. An expected timetable of principal events will be included in the Scheme Document.
• The Scheme is expected to become effective between the middle of May 2022 and 30 June 2022, subject to the satisfaction (or, where applicable, waiver) of the terms set out in Appendix 1 to this announcement.

This summary should be read in conjunction with, and is subject to, the full text of the following announcement (including its Appendices). The Proposed Transaction will be subject to the terms set out in Appendix 1 and to the full terms and conditions to be set out in the Scheme Document. Appendix 2 contains the sources and bases of certain information contained in this summary and the following announcement. Appendix 3 contains details of the irrevocable undertakings received by Eagle. Appendix 4 contains the definitions of certain terms used in this summary and the following announcement.

Additional information for United States investors

The Proposed Transaction relates to the securities of an English company and is proposed to be effected by means of a scheme of arrangement provided for under English law and which will be subject to procedural and disclosure requirements and practices applicable in the UK to schemes of arrangement, which are different from those that may be applicable in the United States. The financial information included in this announcement and the Scheme documentation, if any, has been or will have been prepared in accordance with International Financial Reporting Standards and thus may not be comparable to financial information of United States companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

The New Eagle Shares are being offered pursuant to the Scheme and will be issued in reliance on the exemption from the registration requirements of the United Stated Securities Act of 1933, as amended, provided by Section 3(a)(10) thereof.

Each Acacia Shareholder is urged to consult his or her tax adviser regarding the tax consequences of the Proposed Transaction applicable to him or her.

It may be difficult for United States holders to enforce their rights and any claims they may have arising under the United States federal securities laws.

Forward looking statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Proposed Transaction, and other information published by Eagle and/or Acacia contain statements which are, or may be deemed to be, “forward-looking statements”. Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Eagle and Acacia about future events, and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. The forward-looking statements contained in this announcement may include statements relating to the expected effects of the Proposed Transaction on Eagle and Acacia, the expected timing and scope of the Proposed Transaction and other statements other than historical facts. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as “plans”, “expects” or “does not expect”, “is expected”, “is subject to”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “should”, “would”, “might” or “will” be taken, occur or be achieved. These statements include, but are not limited to, statements regarding future events such as: the strategic fit of Barhemsys® and Byfavo® with Eagle’s specialised hospital-based salesforce; statements regarding the addressable market size and commercial potential for Barhemsys® and Byfavo® and other products or product candidates; the expected structure, anticipated synergies, terms, timing and closing of the Proposed Transaction; Eagle’s marketing, product development, partnering and growth strategy, including relating to the commercialisation of Barhemsys® and Byfavo®, and the ability of Acacia’s technology and know-how to help Eagle achieve its strategy; the expectation that the addition of Barhemsys® and Byfavo® will be accretive to Eagle, and the timing thereof; the expected sources of financing for the Proposed Transaction; the ability of Eagle to expand the application of the Acacia products; the timing, scope or likelihood and timing of regulatory filings and approvals from the FDA for Eagle’s product candidates, including landiolol; the ability of Barhemsys® and Byfavo® to address unmet clinical needs; the ability of Barhemsys® to offer significant economic savings to hospitals and ambulatory centres; the ability of Byfavo® to offer potential health economic benefits and enable shorter procedure times and greater patient throughput; the ability of the Proposed Transaction to create value for Eagle’s shareholders; and the ability of Eagle’s executive team to execute on Eagle’s strategy and build stockholder value.

Although Eagle and Acacia believe that the expectations reflected in such forward-looking statements are reasonable, Eagle and Acacia can give no assurance that such expectations will prove to be correct. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, changes in the global political, economic, business and competitive environments (including, but not limited to, the impacts of the COVID-19 pandemic and geopolitical events such as the conflict in Ukraine); inability to obtain, or meet conditions imposed for, required governmental and regulatory approvals; interruptions or other adverse effects to clinical trials; legal or regulatory developments and changes, including, but not limited to, changes in environmental and health and safety regulations; government actions; foreign exchange rate and interest rate fluctuations; changes in tax rates; weak, volatile or illiquid capital and/or credit markets; market position of the companies comprising the Acacia Group; earnings; financial position; cash flows; return on capital and operating margins; anticipated investments; the ability of Eagle or the Acacia Group to obtain capital/additional finance; an unexpected decline in revenue or profitability; retention of senior management; the maintenance of labour relations; fluctuations in commodity prices and other input costs; operating and financial restrictions as a result of financing arrangements; changes in consumer habits and preferences including a reduction in demand by customers; competitive product and pricing pressures; future business combinations or disposals; success of business and operating initiatives; changes in the level of capital investment; manufacturing and supply chain interruptions, adverse effects on healthcare systems, disruption in the operations of third party partners and disruption of the global economy, and the overall impact of the COVID-19 pandemic or other events on Eagle or Acacia’s business, financial condition and results of operations; whether Eagle will successfully implement its development plan for, and successfully market and commercialise, its product candidates; the success of relationships with partners; the availability and pricing of third party sourced products and materials; the outcome of litigation involving any products or that may have an impact on any of Eagle or Acacia’s products; successful compliance with the FDA and other governmental regulations applicable to product approvals, manufacturing facilities, products and/or businesses; the strength and enforceability of Eagle or Acacia’s intellectual property rights or the rights of third parties; competition from other pharmaceutical and biotechnology companies and the potential for competition from generic entrants into the market; the risks inherent in the early stages of drug development and in conducting clinical trials; the outcome of Acacia’s shareholder vote, the Court and other closing conditions; and factors in addition to the foregoing that may impact Eagle or Acacia’s expectations, including, among other things, any potential business development transactions, acquisitions, restructurings or legal settlements, in addition to any unanticipated factors, that may cause actual results and outcomes to materially differ.

Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. Such forward-looking statements should therefore be construed in the light of such factors. Neither Eagle nor Acacia, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur. You are cautioned not to place undue reliance on these forward-looking statements. Other than in accordance with their legal or regulatory obligations, neither Eagle or Acacia is under any obligation, and Eagle and Acacia expressly disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
