Amryt Pharma plc ("Existing Amryt") is a biopharmaceutical company focused on developing and delivering innovative new treatments to help improve the lives of patients with rare or orphan diseases. Existing Amryt is the marketing authorisation holder and has an exclusive licence to sell lomitapide across the European Economic Area, Middle East and North Africa, Switzerland, Turkey, Israel, Russia, the Commonwealth of Independent States and the non-EU Balkan states.

Lomitapide (under the brand LOJUXTA®) is an approved treatment for adult patients with the rare cholesterol disorder - Homozygous Familial Hypercholesterolaemia ("HoFH"). This disorder impairs the body's ability to remove low density lipoprotein ("LDL") cholesterol ("bad" cholesterol) from the blood. Existing Amryt has also been developing its lead development candidate, AP101, a potential treatment for Epidermolysis Bullosa ("EB"), a rare genetic skin disorder affecting young children and adults for which there is currently no treatment. AP101 is currently in Phase 3 clinical trials. In March 2018, Existing Amryt in-licenced a pre-clinical gene-therapy platform technology, AP103, which offers a potential treatment for patients with recessive dystrophic EB, a subset of EB, and is also potentially relevant to other genetic disorders.

Existing Amryt's shares are admitted to trading on Euronext Growth and the AIM market operated by the London Stock Exchange.

Existing Amryt has entered into agreements to acquire the entire issued share capital of Aegerion Pharmaceuticals, Inc. ("Aegerion"), further details of which are included in the admission document published by Existing Amryt on 27 August 2019 (the "Transaction").

The Transaction constitutes a reverse takeover under Rule 5.19 of the Euronext Growth Markets Rule Book ("Euronext Growth Rules"). The Transaction is conditional upon, inter alia, Existing Amryt receiving shareholder approval for the Transaction including the waiver of obligations under Rule 9 of the The City Code on Takeovers and Mergers, and certain other conditions being satisfied, including the completion of a Chapter 11 bankruptcy process ("Chapter 11") by Aegerion in the USA and a scheme of arrangement becoming effective pursuant to which a new holding company for the Existing Amryt group, as enlarged by the Transaction, will be put in place. The new holding company is currently registered as Amryt Pharma Holdings Limited ("New Amryt"). New Amryt will be re-registered as a public limited company prior to admission of its ordinary shares of 6 pence each ("Ordinary Shares") to trading on Euronext Growth ("Admission") and renamed to Amryt Pharma plc, exchanging its name with Existing Amryt prior to Admission.

Aegerion is a biopharmaceutical company dedicated to developing new standards of care for individuals living with rare and orphan diseases. Headquartered in Boston, Massachusetts, Aegerion maintains operations in the United States, Europe and certain countries in Latin America. Aegerion has two commercial products, metreleptin and lomitapide.

Metreleptin, a recombinant analog of human leptin, is marketed in the US under the brand name MYALEPT® and as MYALEPTA® in the EU. MYALEPT® is approved in the US as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalised lipodystrophy ("GL"). MYALEPTA® is approved in the EU as a treatment for leptin deficiency in patients with congenital or acquired GL in adults and children two years of age and above and familial or acquired partial lipodystrophy in adults and children 12 or over for whom standard treatments have failed to achieve adequate metabolic control.

Lomitapide is marketed in the US by Aegerion under the brand name JUXTAPID® as an

adjunct to a low-fat diet and other lipid-lowering treatments, including low-density lipoprotein to reduce low-density lipoprotein cholesterol, total cholesterol, apolipoprotein B and non-high-density lipoprotein cholesterol in adult patients with HoFH and in the EU under the brand name LOJUXTA®, for the treatment of adult patients with HoFH. JUXTAPID® is also approved in Argentina, Canada, Colombia, Japan and a limited number of other countries. LOJUXTA® is licenced to Existing Amryt for sale in the territories noted above.
