Conference call and webcast today at 0830 EST / 1330 GMT

DUBLIN, Ireland, and Boston MA, March 9, 2022, Amryt (NASDAQ:AMYT), a global, commercial-stage biopharmaceutical company dedicated to acquiring, developing and commercializing novel treatments for rare diseases, today provides a business update and unaudited financial results for Q4 2021 and the full year ended December 31, 2021.

Joe Wiley, CEO of Amryt Pharma, commented: "I am very pleased with today's strong results for 2021 which demonstrate the positive performance and growth that our three commercial products are delivering across a host of metrics including revenue, EBITDA, cash generation and market expansion. Our revenues grew 22% in the year and in particular, metreleptin delivered very impressive 32% revenue growth in 2021. This strong revenue performance drove our eighth consecutive quarter of positive EBITDA and generated full year operating cash flows before Chiasma deal costs of $29.8M.

During the year, we completed the acquisition of Chiasma and I am pleased to report that the integration process is well advanced. We are making significant progress both with the relaunch of Mycapssa® and in advancing new growth opportunities for this key product. Yesterday, we announced the completion of a successful bioavailability study for Mycapssa®. These data support a planned Phase 3 study for Mycapssa® in the treatment of patients with carcinoid symptoms due to neuroendocrine tumors (NET). Mycapssa® is the only FDA approved oral formulation of octreotide for the treatment of acromegaly. The current pharmaceutical standard of care for NET patients with carcinoid symptoms is injectable somatostatin anologs (SSAs). This potential additional indication, if approved, creates a substantial new market opportunity for Amryt.

We also recently refinanced our term debt facilities which further strengthens our balance sheet, significantly reduces our interest costs and extends the maturity profile of those facilities through 2027.

Given the strength of our balance sheet and the sustained performance and growth of our business, the board has approved a share repurchase program of up to $30M that reflects the confidence we have in Amryt's future.

Finally, today we are issuing revenue guidance for FY 2022 of $260M-$270M million which represents growth of 17%-21% on 2021."

³EBITDA, as applied in the above table, is defined as earnings before interest, tax, depreciation, amortisation, impairment, restructuring and severance related costs and share based compensation expenses. To supplement Amryt's financial results presented in accordance with IFRS generally accepted accounting principles, the Company uses EBITDA as a key measure of company performance as the Company believes that this measure is most reflective of the operational profitability or loss of the Company and provides management and investors with useful supplementary information which can enhance their ability to evaluate the operating performance of the business. EBITDA, as measured by the Company, is not meant to be considered in isolation or as a substitute to operating profit / loss attributable to Amryt and should be read in conjunction with the Company's condensed consolidated financial statements prepared in accordance with IFRS.

Oleogel-S10

On February 28, 2022, Amryt announced that the FDA communicated that it had completed its review of the NDA for Oleogel-S10 and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB. During Q2 2022, Amryt intends to discuss with the FDA the nature of the data required to address the Agency's concerns. The EMA review process for Oleogel-S10 in EB is ongoing and Amryt has responded to outstanding questions. Given the rarity of the disease without any approved therapies, the EMA has proposed that an Ad-Hoc Expert Group, comprised of both EB clinical experts and patients with EB, be consulted to provide external and independent EB specific advice. The Ad-Hoc Expert Group is scheduled to meet on March 15, 2022.

Financial Position

In February 2022, the Company completed a $125M non-dilutive debt refinancing which will generate significant annual interest cost savings and extend the maturity of Amryt's debt facilities through February 2027. The facilities also provide strategic flexibility as Amryt looks to grow its global rare disease presence.

Cash generated from operating activities before Chiasma deal costs in 2021 was $29.8M. During the year, the Company paid $12.3M in net finance payments, $3.9M in residual payments related to legacy fines levied on Aegerion, $116.6M on the payment of Chiasma related debt, $16.9M acquisition & restructuring costs and $1.5M in capital expenditure.

Cash of $113.0M at December 31, 2021 (2020: $118.8M) is after repayment of outstanding Chiasma debt, transaction and integration related costs in the period.

Share Repurchase Program

The board of directors has approved a stock repurchase program for the purchase of up to $30 million of the Company's shares at any time. The shares may be repurchased from time to time in the open market or in privately negotiated transactions. The timing, number of shares repurchased, and prices paid for the stock under this program will depend on a variety of factors, including general business and market conditions as well as corporate and regulatory limitations. The Company anticipates funding for this program to come from available corporate funds, including cash on hand and future cash flow.

The term of the board authorization of the repurchase program is until March 8, 2023. There is no guarantee as to the number of shares that will be repurchased, and the repurchase program may be extended, suspended, or discontinued at any time without prior notice at the Company's discretion.

Guidance & Outlook

Given the continued strong performance of the Company's three commercial products, the board is today issuing revenue guidance for FY 2022 in the range of $260M - $270M which represents growth of 17% to 21% on FY 2021.

Amryt is a global commercial-stage biopharmaceutical company focused on acquiring, developing and commercializing innovative treatments to help improve the lives of patients with rare and orphan diseases. Amryt comprises a strong and growing portfolio of commercial and development assets.

Amryt's commercial business comprises three orphan disease products – metreleptin (Myalept®/ Myalepta®); oral octreotide (Mycapssa®); and lomitapide (Juxtapid®/ Lojuxta®).

Myalept®/Myalepta® (metreleptin) is approved in the US (under the trade name Myalept®) as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy (GL) and in the EU (under the trade name Myalepta®) as an adjunct to diet for the treatment of 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 (PL) in adults and children 12 years of age and above for whom standard treatments have failed to achieve adequate metabolic control. For additional information, please follow this link.

Mycapssa® (octreotide capsules) is approved in the US for long-term maintenance therapy in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide. Mycapssa® is the first and only oral somatostatin analogapproved by the FDA. Mycapssa® has also been submitted to the EMA and is not yet approved in Europe. For additional information, please follow this link.

Juxtapid®/Lojuxta® (lomitapide) is approved as an adjunct to a low-fat diet and other lipid-lowering medicinal products for adults with the rare cholesterol disorder, Homozygous Familial Hypercholesterolaemia ("HoFH") in the US, Canada, Colombia, Argentina and Japan (under the trade name Juxtapid®) and in the EU, Israel, Saudi Arabia and Brazil (under the trade name Lojuxta®).

1. General information

Amryt is a global commercial-stage biopharmaceutical company focused on acquiring, developing and commercializing innovative treatments to help improve the lives of patients with rare and orphan diseases. Amryt comprises a strong and growing portfolio of commercial and development assets.

As used herein, references to ‘‘we,'' ‘‘us,'' ‘‘Amryt'' or the ‘‘Group'' in these condensed consolidated interim financial statements shall mean Amryt Pharma plc and its global subsidiaries, collectively. References to the ‘‘Company'' in these condensed consolidated interim financial statements shall mean Amryt Pharma plc.

Amryt Pharma plc is a company incorporated in England and Wales. The Company is listed on Nasdaq (ticker: AMYT).

Amryt acquired Chiasma, Inc. ("Chiasma") in August 2021. The combined company will be a global leader in rare and orphan diseases with three on-market commercial products, a global commercial and operational footprint and a significant development pipeline of therapies with the financial flexibility to execute its growth plans. Amryt's commercial business comprises three orphan disease products – metreleptin (Myalept®/ Myalepta®); oral octreotide (Mycapssa®); and lomitapide (Juxtapid®/ Lojuxta®).

Amryt's lead development candidate, Oleogel-S10 is a potential treatment for the cutaneous manifestations of Junctional and Dystrophic Epidermolysis Bullosa (EB), a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment. Filsuvez® has been selected as the brand name for Oleogel-S10. The product does not currently have regulatory approval to treat EB. On February 28, 2022, Amryt announced that the FDA communicated that it had completed its review of the NDA for Oleogel-S10 and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB. Amryt intends to discuss with the FDA the nature of the data required to address the Agency's concerns. The European Medicines Agency ("EMA") review process for Oleogel-S10 in EB is ongoing and Amryt has responded to outstanding questions. Given the rarity of the disease without any approved therapies, the EMA has proposed that an Ad-Hoc Expert Group, comprised of both EB clinical experts and patients with EB, be consulted to provide external and independent EB specific advice. The Committee for Medicinal Products for Human Use ("CHMP") opinion is now anticipated in March 2022.

2. Accounting policies

Basis of preparation

The condensed consolidated interim financial statements of the Group have been prepared in accordance with IAS 34: Interim Financial Reporting. They do not include all of the information required in annual financial statements in accordance with International Financial Reporting Standards (‘‘IFRS'') and should be read in conjunction with the annual consolidated financial statements for the year ended December 31, 2020. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the Group's financial position and performance since the last annual financial statements. The accounting policies used in the preparation of the interim financial information are the same as those used in the Group's audited financial statements for the year ended December 31, 2020, and those which are expected to be used in the financial statements for the year ended December 31, 2021.

Basis of going concern

Having considered the Group's current financial position and cash flow projections, the Board of Directors believes that the Group will be able to continue in operational existence for at least the next 12 months from the date of approval of these condensed consolidated interim financial statements and that it is appropriate to continue to prepare the condensed consolidated interim financial statements on a going concern basis.

As part of their inquiries, the Board of Directors reviewed budgets, projected cash flows, and other relevant information for a period not less than 12 months from the date of approval of the condensed consolidated interim financial statements for the year ended December 31, 2021.

Basis of consolidation

The condensed consolidated interim financial statements comprise the financial statements of the Group for the year ended December 31, 2021. Subsidiaries are entities controlled by the Company. Where the Company has control over an investee, it is classified as a subsidiary. The Company controls an investee if all three of the following elements are present: power over an investee, exposure, or rights to variable returns from its involvement with the investee and the ability to use its power to affect those variable returns. Control is reassessed whenever facts and circumstances indicate that there may be a change in any of these elements of control.

Subsidiaries are fully consolidated from the date that control commences until the date that control ceases. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group. Intergroup balances and any unrealized gains or losses, income or expenses arising from intergroup transactions are eliminated in preparing the condensed consolidated interim financial statements.

Presentation of balances

The condensed consolidated interim financial statements are presented in U.S. dollars (‘‘US$''), rounded to the nearest thousand, which is the functional currency of the Company and presentation currency of the Group.

The following table discloses the major exchange rates of those currencies other than the functional currency of US$ that are utilized by the Group:

Changes in accounting policies and disclosures

There are no new standards and amendments to IFRS effective as of January 1, 2021, that are relevant to the Group.

Critical accounting judgements and key sources of estimation uncertainty

In preparing these condensed consolidated interim financial statements in conformity with IFRS management is required to make judgements, estimates and assumptions that affect the application of policies and amounts reported in the condensed consolidated interim financial statements and accompanying notes. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgements about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and future periods if the revision affects both current and future periods.

The significant estimates, assumptions or judgements, applied in the condensed consolidated interim financial statements were the same as those applied in the Group's audited financial statements for the year ended December 31, 2020.

Principal accounting policies

The condensed consolidated interim financial statements have been prepared in accordance with the accounting policies adopted in the Group's audited financial statements for the year ended December 31, 2020.

3. Segment information

The Group is a global, commercial-stage biopharmaceutical company dedicated to commercializing and developing novel therapeutics to treat patients suffering from serious and life-threatening rare diseases.

The Group currently operates as one business segment, pharmaceuticals, and is focused on the development and commercialization of three commercial products and a number of development products. The Group derives its revenues primarily from one source, being the pharmaceutical sector with high unmet medical need.

The Group's Chief Executive Officer, Joseph Wiley, is currently the Company's chief operating decision maker (‘‘CODM''). The Group does not operate any separate lines of business or separate business entities with respect to its products. Accordingly, the Group does not accumulate discrete financial information with respect to separate service lines and does not have separate reportable segments.

4. Share based payments

Share-based Compensation Plans

Amryt's Equity Incentive Plan

Amryt's Equity Incentive Plan was established by a special resolution on September 23, 2019, and was subsequently amended by the Board on May 18, 2020, and August 3, 2021. The purpose of the Plan is to provide for the granting of Equity Incentives to Directors and Employees of, and Consultants to, the Company or any Associated Company.

Chiasma Equity Incentive Plan

When Amryt acquired Chiasma in August 2021, the Chiasma Stock Option and Incentive Plan transferred across to Amryt. Each outstanding and unexercised Chiasma Stock Option or RSU, whether vested or not vested, ceased to represent a right to acquire shares of Chiasma common stock and were converted into an option to purchase Amryt ADSs on the same terms and conditions as were applicable under such Chiasma Stock Option and Incentive Plan immediately prior to the acquisition.

No new stock option or RSUs will be granted under the Chiasma stock option and incentive plan.

Terms and Conditions of New Grants and Grants Under the Chiasma Equity Incentive Plan

The terms and conditions of new grants are as follows, whereby all options are settled by physical delivery of shares:

Vesting conditions

The employee share options vest following a period of service by the officer or employee. The required period of service is determined by the Remuneration Committee at the date of grant of the options (usually the date of approval by the Remuneration Committee). There are no market conditions associated with the share option vesting periods.

Contractual life

The term of an option is determined by the Remuneration Committee provided that the term may not exceed a period of seven to ten years from the date of grant. All options will terminate 90 days after termination of the option holder's employment, service or consultancy with the Group except where a longer period is approved by the Board of Directors. Under certain circumstances involving a change in control of the Group, some options will automatically accelerate and become exercisable in full as of a date specified by the Board of Directors.

The number and weighted average exercise price (in Sterling pence) of share options per ordinary share granted under Amryt's Equity Incentive Plan and the Chiasma stock option and incentive plan is as follows:

	Amryt Equity Incentive Plan		Chiasma Stock Option and Incentive Plan

The fair value of the Amryt equity award is estimated at the date of grant using the Black-Scholes pricing model, taking into account the terms and conditions attached to the grant. The fair value of the Chiasma equity awards transferred to Amryt on acquisition were measured in accordance with IFRS 2. The portion of the value of the equity transferred to Amryt attributable to pre-combination service is included in the consideration at the date of acquisition. The portion of the equity awards transferred to Amryt attributable to post combination service is estimated at the date of transfer using Black Scholes pricing model, taking into account the terms and conditions attached to the grant.

The following are the inputs to the model for the equity instruments granted during the period:

Under the terms of Amryt's Equity Incentive Plan, restricted share units ("RSUs") to purchase 1,568,755 ordinary shares were outstanding at December 31, 2021. Under the terms of this plan, RSUs are granted to officers, consultants and employees of the Group at the discretion of the Remuneration Committee. For the year ended December 31, 2021, a total of 625,205 RSUs were granted to employees of the Company. For the year ended December 31, 2020, a total of 1,556,960 RSUs were granted to employees of the Company. The fair value of the RSUs is based on the share price at the date of grant, with the expense spread over the vesting period. The fair value of RSUs granted in the year ended December 31, 2021, was US$1,636,000. At December 31, 2021, the total RSUs granted to date have a weighted remaining contractual life of 1.9 years.

Warrants

There are no outstanding warrants at December 31, 2021 (December 31, 2020: 9,312,062). In August 2021, an Amryt institutional investor exercised subscription rights relating to 8,966,520 zero cost warrants. These warrants were issued in September 2019 as part of the Company's acquisition of Aegerion. Certain institutional investors elected to receive warrants to subscribe for new ordinary shares of £0.06 each in Amryt ("Ordinary Shares"), in place of the same number of Ordinary Shares, as consideration for the Company's acquisition of Aegerion and their equity investments in the Company in September 2019. Each warrant entitled the holder to subscribe for one Ordinary Share for no additional consideration.

Separate warrants consisting of 345,542 as at December 31, 2020, which were issued in connection with the admission to the AIM in 2016, are no longer outstanding; 283,389 warrants were exercised in March 2021 and 62,153 warrants lapsed in April 2021.

5. Business combinations and asset acquisitions

Acquisition of Chiasma

On May 5, 2021, Amryt announced that it had signed a definitive agreement to acquire Chiasma, Inc. (NASDAQ:CHMA) in an all-stock combination. Under the terms of the transaction, each share of Chiasma common stock issued and outstanding prior to the consummation of the transaction was exchanged for 0.396 Amryt American Depositary Shares ("ADSs"), each representing five Amryt ordinary shares.

On August 5, 2021, Amryt completed the acquisition of Chiasma, Inc. and, in conjunction with the completion, Amryt allotted and issued a total of 127,733,680 ordinary shares as consideration for the acquisition. Following the completion, shareholdings in Chiasma were rounded in being converted to Amryt shares using the exchange ratio of 0.396. Roundings in converting Chiasma shareholdings to Amryt shares were finalized in August 2021 and resulted in an additional 7,015 ordinary shares being allotted and issued by Amryt as consideration for the acquisition. In total, these ordinary shares were issued to the former Chiasma Shareholders in the form of 25,548,139 ADSs at US$10.19 per share, to acquire Chiasma for a value of US$260,336,000.

On August 5, 2021, Chiasma had outstanding equity awards that were held by Chiasma employees. The fair value of these awards transferred to Amryt on acquisition were measured in accordance with IFRS 2. The portion of the value of the equity transferred to Amryt attributable to pre-combination service is included in the consideration at the date of acquisition and this amounted to US$10,157,000.

On August 5, 2021, the Group repaid US$116,629,000 of Chiasma long term debt.

The combined company will be a global leader in rare and orphan diseases with three on-market commercial products, a global commercial and operational footprint and a significant development pipeline of therapies with the financial flexibility to execute its growth plans.

The table below reflects the fair value of the identifiable net assets acquired in respect of the acquisition completed during the period. Any amendments to fair values will be made within the twelve-month period from the date of acquisition, as permitted by IFRS 3: Business Combinations.

The acquired goodwill is attributable principally to the profit generating potential of the businesses, the assembled workforce and benefits arising from embedded infrastructure, that are expected to be achieved from integrating the acquired businesses into the Group's existing business. No amount of goodwill is expected to be deductible for tax purposes.

In the post-acquisition period to December 31, 2021, the business acquired during the current year contributed revenue of US$6,407,000 and a trading loss of US$22,602,000 including restructuring and acquisition costs, to the Group's results. The full year unaudited revenue and trading loss for the Group had the acquisitions taken place at the start of the year, would have been US$228,554,000 and US$82,532,000 respectively.

The gross contractual value of trade and other receivables as at the dates of acquisition amounted to US$7,180,000, which approximated the fair value of these accounts as the amount not expected to be collected was insignificant.

The Group incurred acquisition and restructuring related costs of US$2,268,000 and US$16,947,000 for the three-month period and year ended December 31, 2021, respectively, relating to external legal fees, advisory fees, due diligence costs and severance costs related to the acquisition of Chiasma. These costs have been included in operating costs in the Condensed Consolidated Statement of Comprehensive Income/(Loss).

The initial assignment of fair values to identifiable net assets acquired has been performed on a provisional basis due to the relative size of the acquisition and the timing of the transaction. Any amendments to these fair values within the twelve-month timeframe from the date of acquisition will be disclosed in the 2022 consolidated financial statements, as stipulated by IFRS 3.

Acquisition of Aegerion Pharmaceuticals

On May 20, 2019, Amryt entered into a Restructuring Support Agreement (as subsequently amended on June 12, 2019) and Plan Funding Agreement pursuant to which, among other matters, Amryt agreed to the acquisition of Aegerion Pharmaceuticals, Inc. (‘‘Aegerion'', subsequently renamed as Amryt Pharmaceuticals Inc.), a former wholly-owned subsidiary of Novelion Therapeutics Inc. (‘‘Novelion''). On May 20, 2019, Aegerion and its U.S. subsidiary, Aegerion Pharmaceuticals Holdings, Inc., filed voluntary petitions under Chapter 11 of Title 11 of the U.S. Code in the Bankruptcy Court. On September 24, 2019, Amryt completed the acquisition of Aegerion. Amryt acquired Aegerion upon its emergence from bankruptcy in an exchange for ordinary shares and zero cost warrants in Amryt. Amryt issued 85,092,423 effective shares at US$1.793 per share, which is made up of 77,027,423 ordinary shares and 8,065,000 zero cost warrants, to acquire Aegerion for a value of US$152,615,000.

As part of the acquisition of Aegerion, it was agreed, for certain Aegerion creditors who wished to restrict their percentage share interest in Amryt's issued share capital, to issue to the relevant Aegerion creditor, as an alternative to Amryt's ordinary shares, an equivalent number of new zero cost warrants to subscribe for Amryt's ordinary shares to be constituted on the terms of the zero cost warrant. As at December 31, 2021, no zero cost warrants were remaining.

During the three-month period and year ended December 31, 2021, the Group incurred no additional acquisition and restructuring related costs relating to external legal fees, advisory fees, due diligence costs and severance costs related to the acquisition of Aegerion (December 31, 2020: US$12,000 and US$1,017,000, respectively).

Contingent Value Rights

Related to the Aegerion acquisition, Amryt issued Contingent Value Rights (‘‘CVRs'') pursuant to which up to US$85,000,000 may become payable to Amryt's shareholders and optionholders, who were on the register prior to the completion of the acquisition on September 20, 2019, if certain approval and revenue milestones are met in relation Oleogel-S10, Amryt's lead product candidate. If any such milestone is achieved, Amryt may elect to pay the holders of CVRs by the issue of Amryt shares or loan notes. If Amryt elects to issue Loan Notes to holders of CVRs, it will settle such loan notes in cash 120 days after their issue. If none of the milestones are achieved, scheme shareholders and optionholders will not receive any additional consideration under the terms of the CVRs. In these circumstances, the value of each CVR would be zero.

The terms of the CVRs are as follows:

The total CVR payable is up to US$85,000,000

This is divided into three milestones which are related to the success of Oleogel-S10 (the Group's lead development asset)

FDA approval
- US$35,000,000 upon FDA approval
- 100% of the amount due if approval is obtained before December 31, 2021, with a sliding scale on a linear basis to zero if before July 1, 2022
EMA approval
- US$15,000,000 upon EMA approval
- 100% of the amount due if approval is obtained before December 31, 2021, with a sliding scale on a linear basis to zero if before July 1, 2022
Revenue targets
- US$35,000,000 upon Oleogel-S10 revenues exceeding US$75,000,000 in any 12-month period prior to June 30, 2024
Payment can at the Board's discretion be in the form of either:
- 120-day loan notes (effectively cash), or
- Shares valued using the 30 day / 45-day VWAP.

The CVRs were contingent on the successful completion of the acquisition and, accordingly, have been based on fair value as at September 24, 2019. The CVRs have been classified as a financial liability in the Condensed Consolidated Statement of Financial Position. Given that CVRs were issued to legacy Amryt shareholders in their capacity as owners of the identified acquirer as opposed to the seller in the transaction, management concluded that the most appropriate classification would be to recognize the CVR as a distribution on consolidation instead of goodwill.

Measurement of CVRs

As at December 31, 2021, the carrying value of the CVRs was US$18,734,000 (December 31, 2020: US$61,417,000). The value of the potential payout was calculated using the probability-weighted expected returns method. Using this method, the potential payment amounts were multiplied by the probability of achievement and discounted to present value. The probability adjusted present values took into account published orphan drug research data and statistics which were adjusted by management to reflect the specific circumstances applicable to the type of product acquired in the Amryt GmbH transaction. The probability chance of success, based on management's expertise and experience for orphan drugs and taking into account the unique circumstances applying to approval process of this product, was estimated at 60% in the year ended December 31, 2021 (2020: 89%). This estimate reflects the current facts and circumstances at the time of preparation of the unaudited Condensed Consolidated Financial Statements and may change for updated facts and circumstances up until the point in time of filing the Group's audited annual Consolidated Financial Statements for the year ended December 31, 2021. Discount rates of 10% and 16.5%, as applicable, were used in the calculation of the present value of the estimated contractual cash flows for the year ended December 31, 2021, based on the applicable rates determined on the acquisition date. Management was required to make certain estimates and assumptions in relation to revenue forecasts, timing of revenues and probability of achievement of commercialization of Oleogel-S10. However, management notes that, due to issues outside their control (i.e. regulatory requirements and the commercial success of the product), the timing of when such revenue targets may occur may change. Such changes may have a material impact on the assessment of the expected cash flows of the CVRs. The impact of a 20% increase in the probability of success used would result in an increase to the fair value of US$6,245,000, whereas a decrease would have the opposite effect.

Amryt reviews the expected cash flows on a regular basis as the discount on initial recognition is being unwound as financing expenses in the Condensed Consolidated Statement of Comprehensive Income/(Loss) over the life of the obligation. It is reviewed on a quarterly basis and the appropriate finance charge or gain is booked in the Condensed Consolidated Statement of Comprehensive Income/(Loss) on a quarterly basis. The Group received positive topline data from the phase 3 EASE trial of Oleogel-S10 in September 2020. The product does not currently have regulatory approval to treat EB but has been submitted to the FDA for approval and in June 2021, Amryt received confirmation from the FDA that its NDA for Oleogel-S10 had been accepted and granted priority review. On February 28, 2022, Amryt announced that the FDA communicated that it had completed its review of the NDA for Oleogel-S10 and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB. Amryt intends to discuss with the FDA the nature of the data required to address the Agency's concerns. In Europe, a MAA for Oleogel-S10 was accepted for assessment by the EMA in March 2021. The EMA review process for Oleogel-S10 in EB is ongoing and Amryt has responded to outstanding questions. Given the rarity of the disease without any approved therapies, the EMA has proposed that an Ad-Hoc Expert Group, comprised of both EB clinical experts and patients with EB, be consulted to provide external and independent EB specific advice. The CHMP opinion is now anticipated in March 2022.

The total non-cash gain recognized in the Condensed Consolidated Statement of Comprehensive Income/(Loss) for the three months and year ended December 31, 2021, is US$48,198,000 and US$42,683,000 (December 31, 2020: charge US$7,506,000 and US$12,004,000, respectively).

Acquisition of Amryt GmbH (previously ‘‘Birken'')

Amryt DAC signed a conditional share purchase agreement to acquire Amryt GmbH on October 16, 2015 (‘‘Amryt GmbH SPA''). The Amryt GmbH SPA was completed on April 18, 2016, with Amryt DAC acquiring the entire issued share capital of Amryt GmbH. The consideration included contingent consideration comprising milestone payments and sales royalties as follows:

Milestone payments of:
- €10,000,000 on receipt of marketing approval by the EMA or FDA of a pharmaceutical product containing Betulin as its API for the treatment of EB;
- €10,000,000 once net ex-factory sales/net revenue of Oleogel S-10 first exceed €50,000,000 in any calendar year;
- €15,000,000 once net ex-factory sales/net revenue of Oleogel S-10 first exceed €100,000,000 in any calendar year;
Royalties of 9% on sales of Oleogel-S10 products for 10 years from first commercial sale.

Fair Value Measurement of Contingent Consideration

As at December 31, 2021, the fair value of the contingent consideration was estimated to be US$52,989,000 (December 31, 2020: US$86,906,000). The fair value of the contingent consideration included milestone payments determined using probability adjusted present values and probability weighted revenue forecasts (see Note 16, Fair value measurement and financial risk management, for fair value hierarchy applied and impact of key unobservable impact data). The probability adjusted present values took into account published orphan drug research data and statistics which were adjusted by management to reflect the specific circumstances applicable to the type of product acquired in the Amryt GmbH transaction. The probability chance of success, based on management's expertise and experience for orphan drugs and taking into account the unique circumstances applying to approval process of the product, was estimated at 60% for the period ended December 31, 2021 (December 31, 2020: 89%). This estimate reflects the current facts and circumstances at the time of preparation of the unaudited Condensed Consolidated Financial Statements and may change for updated facts and circumstances up until the point in time of filing the Group's audited annual Consolidated Financial Statements for the year ended December 31, 2021. A discount rate of 7.9% was used in the calculation of the fair value of the contingent consideration for the year ended December 31, 2021 (December 31, 2020: 14.4%).

Amryt reviews the expected cash flows on a regular basis as the discount on initial recognition is being unwound as financing expense/gain in the Condensed Consolidated Statement of Comprehensive Income/(Loss) over the life of the obligation. It is reviewed on a quarterly basis and the appropriate finance charge or gain is booked in the Condensed Consolidated Statement of Comprehensive Income/(Loss) on a quarterly basis. The Group received positive topline data from the phase 3 EASE trial of Oleogel-S10 in September 2020. The product does not currently have regulatory approval to treat EB but has been submitted to the FDA for approval and in June 2021, Amryt received confirmation from the FDA that its NDA for Oleogel-S10 had been accepted and granted priority review. On February 28, 2022, Amryt announced that the FDA communicated that it had completed its review of the NDA for Oleogel-S10 and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB.

Given the rarity of the disease without any approved therapies, the EMA has proposed that an Ad-Hoc Expert Group, comprised of both EB clinical experts and patients with EB, be consulted to provide external and independent EB specific advice. The CHMP opinion is now anticipated in March 2022.

The total non-cash finance gain recognized in the Condensed Consolidated Statement of Comprehensive Income/(Loss) for the three months and year ended December 31, 2021, is US$35,520,000 and US$26,623,000 (December 31, 2020: charge of US$19,677,000 and US$27,827,000, respectively).

6. Earnings/(loss) per share – basic and diluted

The weighted average number of shares in the earnings and loss per share (‘‘LPS'') calculation, reflects the weighted average total actual shares of Amryt Pharma plc in issue at December 31, 2021.

Issued share capital – ordinary shares of £0.06 each

	Number of shares	Weighted average shares
	As at December 31	Three months ended December 31,	Year ended December 31,

2020 (unaudited)	178,801,593	166,974,713	158,591,356

The calculation of earnings/(loss) per share is based on the following:

	Three months ended December 31,		Year ended December 31,
	2021 (unaudited)	2020 (unaudited)	2021 (unaudited)	2020 (audited)
Profit/(loss) after tax attributable to equity holders of the Company (US$'000)	22,374	(46,990)	(18,171)	(104,527)
Weighted average number of ordinary shares in issue	318,881,440	166,974,713	235,852,023	158,591,356
Fully diluted average number of ordinary shares in issue	328,050,794	166,974,713	235,852,023	158,591,356
Basic earnings/(loss) per share (US$)	0.07	(0.28)	(0.08)	(0.66)
Diluted earnings/(loss) per share (US$)	0.07	(0.28)	(0.08)	(0.66)

Where a loss has occurred, basic and diluted LPS are the same because the outstanding share options and warrants are anti-dilutive. Accordingly, diluted LPS equals the basic LPS. The share options, RSUs and warrants outstanding as at December 31, 2021, totaled 40,898,377 (December 31, 2020: 29,615,620) and are potentially dilutive.

Developed technology on commercially marketed products

In connection with the acquisition of Aegerion in September 2019, the Group acquired developed technology, metreleptin and lomitapide. These intangible assets are amortized over their estimated useful lives and the remaining useful lives for metreleptin and lomitapide are approximately 4.2 and 5.7 years, respectively, as of December 31, 2021 (December 31, 2020: 5.2 and 6.7 years, respectively).

In connection with the acquisition of Chiasma in August 2021, the Group acquired developed technology, octreotide. This intangible asset is amortized over its estimated useful life and the remaining useful life is approximately 14.2 years as of December 31, 2021.

In-process R&D

As a result of the acquisition of Amryt GmbH, in 2016, the Group recognized in-process R&D costs of €48,453,000/US$54,872,000 which is related to the Group's lead development asset, Oleogel-S10. During the three-month period and year ended December 31, 2021, an impairment charge was recognized on the in-process R&D intangible asset related to Oleogel-S10. This was determined following the receipt of a Complete Response Letter (CRL) from the FDA, in which the FDA communicated that it had completed its review of the NDA for Oleogel-S10 and has determined that the application cannot be approved in its present form. The impairment charge recognized in the Condensed Consolidated Statement of Comprehensive Income/(Loss) was €28,867,000/US$32,623,000, there was no impairment charge recognized in the three-month period and year ended December 31, 2020.

The remaining in-process R&D is a result of the acquisition of Cala Medical Limited in October 2020.

Goodwill

During 2019, the Group completed the acquisition of Aegerion which resulted in the recognition of goodwill that has a carrying value of US$18,080,000. On August 5, 2021, the Group completed the acquisition of Chiasma, which resulted in aggregate goodwill of US$38,608,000.

The Group reviews events or changes in circumstances that may indicate a triggering event for impairment, at each reporting date, and conducts an annual impairment review to determine any impairment charge required. Management completed an impairment review by determining recoverable amounts from value in use calculations. The recoverable amount of an asset or cash generating unit is estimated in order to determine the extent of an impairment charge. As noted above, in the three months and year ended December 31, 2021, there was an impairment charge recognized on In-process R&D intangible assets related to Oleogel-S10. There was no other impairment charge recognized during the three months and year ended December 31, 2021.

Work in progress	12,986	3,903
Finished goods	65,933	11,627
Inventories	115,769	40,992

The increase in inventories for the year ended December 31, 2021, reflected the fair value of inventory acquired as part of the acquisition of Chiasma on August 5, 2021. The fair value of the acquired inventory amounted to US$65,907,000. Inventory on hand at the date of acquisition was valued at the expected selling price less the sum of remaining costs of disposal, cost to complete and a reasonable profit margin for the selling effort of the acquiring entity. The costs to complete were calculated based on costs incurred on recently completed finished goods. The costs to dispose include sales and marketing expenses required to sell the product to the customer in addition to certain general and administrative expenses expected to be incurred by Amryt. This resulted in a non-cash step up at the valuation of inventory at August 5, 2021, of US$44,794,000. The non-cash step up in inventory is being unwound to the Condensed Consolidated Statement of Comprehensive Income/(Loss) over the period in which this saleable inventory is sold. At December 31, 2021, US$41,581,000 of this non-cash inventory step up is included in inventory.

Cash and cash equivalents include cash at bank available on demand and restricted cash.

At December 31, 2021, there was US$261,000 restricted cash (December 31, 2020: US$223,000). The restricted cash balance as at December 31, 2021, consists of a deposit on a company credit card facility for an amount of US$126,000 (December 31, 2020: US$150,000), a lease deposit for US$85,000 (December 31, 2020: nil) and a letter of credit related to US customs which was put in place for an amount of US$50,000 (December 31, 2020: nil). The restricted cash balance as at December 31, 2020, included US$73,000 held by a third-party distributor that was received in January 2021. There was no cash in transit held by a third-party distributor as at December 31, 2021.

Share Capital

Share capital represents the cumulative par value arising upon issue of ordinary shares of Sterling 6 pence each.

The ordinary shares have the right to receive notice of, attend and vote at general meetings and participate in the profits of the Company.

Share Premium

Share premium represents the consideration that has been received in excess of the nominal value on issue of share capital net of issue costs and transfers to distributable reserves.

Warrant reserve

The warrant reserve represents zero cost warrants issued as part of the equity raise on September 24, 2019, net of issue costs apportioned to warrants issued and additional warrants issued to certain shareholders on November 14, 2019. Each warrant entitles the holder to subscribe for one ordinary share at zero cost. The Company issued 4,000,000 and 4,229,753 ordinary shares on July 15, 2020, and September 22, 2020, respectively, in exchange for certain warrants. The remaining warrants were exchanged on August 5, 2021, and the Company issued 8,966,520 ordinary shares, 4,208,314 of which were issued from treasury shares. There were no remaining warrants outstanding as at December 31, 2021.

Treasury Shares

In October 2020, the Company issued 72,953 ordinary shares from treasury shares following the exercise of share options. In March 2021, the Company issued a total of 583,389 ordinary shares from treasury shares, 300,000 ordinary shares relating to the exercise of share options and 283,389 ordinary shares following the exchange of certain warrants. In August 2021, the company issued 4,208,314 ordinary shares from treasury shares in conjunction with the exchange of warrants. There were no treasury shares held as at December 31, 2021.

Share based payment reserve

Share based payment reserve relates to the charge for share based payments in accordance with IFRS 2. In March 2021, the Company issued 283,389 ordinary shares in exchange for certain warrants. In April 2021, 62,153 warrants lapsed. During the year ended December 31, 2021, the Company issued 3,722,550 ordinary shares in relation to the exercise of share options and RSUs.

As part of the acquisition of Chiasma, the Company replaced share awards that were existing at the time of the acquisition. This resulted in the recognition of a share-based payment reserve of US$10,157,000 on acquisition.

Merger reserve

The merger reserve was created on the acquisition of Amryt DAC by Amryt Pharma plc in April 2016. Ordinary shares in Amryt Pharma plc were issued to acquire the entire issued share capital of Amryt DAC. Under section 612 of the UK Companies Act 2006, the premium on these shares has been included in a merger reserve.

Reverse acquisition reserve

The reverse acquisition reserve arose during the period ended December 31, 2016, in respect of the reverse acquisition of Amryt Pharma plc by Amryt DAC. Since the shareholders of Amryt DAC became the majority shareholders of the enlarged Group, the acquisition is accounted for as though there is a continuation of Amryt DAC's financial statements. The reverse acquisition reserve is created to maintain the equity structure of Amryt Pharma plc in compliance with UK company law.

Equity component of convertible notes

The equity component of convertible notes represents the equity component of the US$125,000,000 convertible debt and is measured by determining the residual of the fair value of the instrument less the estimated fair value of the liability component. The equity component is recognized in equity and is not subsequently remeasured.

Other distributable reserves

Other distributable reserves comprise the following:

Distribution of the share premium amount on 6 November 2019 of US$268,505,000. By special resolution of the Company duly passed on 23 September 2019, it was resolved that the entire amount outstanding to the credit of the share premium account and capital redemption reserve of the Company be cancelled. The reduction in capital, amounting to US$268,505,000, representing the entire amount of share premium at that time, was approved by the High Court of Justice of England and Wales on 5 November 2019.
A deemed distribution of US$47,902,000 arising from the issuance of CVRs in September 2019.
A deemed distribution of US$2,969,000 arising from the scheme of arrangement in September 2019 whereby Amryt Pharma plc, which was incorporated in July 2019, became a 100% shareholder of Amryt Pharma Holdings Limited (formerly named Amryt Pharma plc) (the "Acquisition of subsidiary without a change of control")

Currency translation reserve

The currency translation reserve arises on the retranslation of non-U.S. dollar denominated foreign subsidiaries.

Accumulated deficit

Accumulated deficit represents losses accumulated in previous periods and the current year.

As part of the acquisition of Aegerion on September 24, 2019, Aegerion entered into a new U.S. dollar denominated US$81,021,000 secured term loan debt facility (‘‘Term Loan'') with various lenders. The Term Loan was made up of a US$54,469,000 loan that was in place prior to the acquisition, which was refinanced as part of the acquisition, and a US$26,552,000 additional loan that was drawn down on September 24, 2019. The Term Loan had a five-year term from the date of the draw down, September 24, 2019, and a maturity date of September 24, 2024. Under the Term Loan, interest was payable at the option of the Group at the rate of 11% per annum paid in cash on a quarterly basis or at a rate of 6.5% paid in cash plus 6.5% paid in kind, which rolls up and is included in the principal balance outstanding, on a quarterly basis. Unpaid accrued interest of US$1,536,000 as at December 31, 2021 is recognized in current liabilities within trade and other payables (December 31, 2020: $1,439,000). The Term Loan agreement includes an option to prepay the loan in whole or in part at any time subject to payment of an exit fee, which depending on the stage of the loan term, ranges from 5.00% to 0.00% of the principal then outstanding on the Term Loan. On February 18, 2022, the Term Loan was repaid in full and the Group secured a $125,000,000 senior credit facility of which US$105,000,000 was drawn down to facilitate the prepayment of the existing Term Loan. See further details on the $125,000,000 senior credit facility entered into by Amryt in Note 16, Events after the reporting period.

In connection with the Term Loan, the Group incurred approximately US$870,000 of debt issuance costs, which primarily consisted of underwriting, legal and other professional fees. These costs are amortized over the expected life of the loan using the effective interest method.

The Term Loan was guaranteed by Amryt and certain subsidiaries of the Group. In connection with the loan agreement, fixed and floating charges have been placed on property and undertakings of Amryt and certain subsidiaries of the Group.

The Term Loan agreement included affirmative and negative covenants, including prohibitions on the incurrence of additional indebtedness, granting of liens, certain asset dispositions, investments, and restricted payments, in each case, subject to certain exceptions set forth in the Loan Agreement. The Term Loan agreement also includes customary events of default for a transaction of this type and includes (i) a cross-default to the occurrence of any event of default under material indebtedness of Amryt and certain subsidiaries of the Group and Amryt, including the convertible notes, and (ii) Amryt or any of its subsidiaries being subject to bankruptcy or other insolvency proceedings. Upon the occurrence of an event of default, the lenders may declare all of the outstanding Term Loan and other obligations under the Term Loan agreement to be immediately due and payable and exercise all rights and remedies available to the lenders under the Term Loan agreement and related documentation. There were no events of default or breaches of the covenants occurring for the three months and year ended December 31, 2021 (December 31, 2020: no events).

As part of the Aegerion acquisition, Aegerion issued convertible notes with an aggregate principal amount of US$125,000,000 to Aegerion creditors.

The convertible notes are senior unsecured obligations and bear interest at a rate of 5.0% per year, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2020. The convertible notes will mature on April 1, 2025, unless earlier repurchased or converted.

The convertible notes are convertible into Amryt's ordinary shares at a conversion rate of 386.75 ordinary shares per US$1,000 principal amount of the convertible notes. If the holders elect to convert the convertible notes, Amryt can settle the conversion of the convertible notes through payment or delivery of cash, common shares, or a combination of cash and common shares, at its discretion. As a result of the conversion feature in the convertible notes, the convertible notes were assessed to have both a debt and an equity component. The two components were assessed separately and classified as a financial liability and equity instrument. The financial liability component was measured at fair value based on the discounted cash flows expected over the expected term of the notes using a discount rate based on a market interest rate that a similar debt instrument without a conversion feature would be subject to. Refer to Note 11, Share capital and reserves, for further details on the equity component of the convertible notes.

From September 24, 2019, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their convertible notes, in multiples of US$1,000 principal amount, at the option of the holder.

The indenture does not contain any financial covenants or restrict the Group's ability to repurchase securities, pay dividends or make restricted payments in the event of a transaction that substantially increases the Group's level of indebtedness in certain circumstances.

The indenture contains customary terms and covenants and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving Aegerion, Amryt and certain subsidiaries of the Group) occurs and is continuing, the trustee by notice to Amryt, or the holders of at least 25% in principal amount of the outstanding convertible notes by written notice to Amryt and the trustee, may declare 100% of the principal of and accrued and unpaid interest, if any, on all of the convertible notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving Amryt, 100% of the principal and accrued and unpaid interest, if any, on the convertible notes will become due and payable automatically. Notwithstanding the foregoing, the indenture provides that, upon Amryt's election, and for up to 180 days, the sole remedy for an event of default relating to certain failures by Amryt to comply with certain reporting covenants in the indenture consists exclusively of the right to receive additional interest on the convertible notes. There have been no events of default or breaches of the covenants occurring for the year ended December 31, 2021 (2020: no events).

Legal matters

Prior to the acquisition of Aegerion by Amryt, Aegerion entered into settlement agreements with governmental entities including the Department of Justice (‘‘DOJ'') and the FDA in connection with Juxtapid investigations. The settlement agreements require Aegerion to pay specified fines and engage in regulatory compliance efforts. Subsequent to the acquisition, Aegerion made US$23,036,000 of settlement payments, including interest. The settlements have been paid in full with the last payment completed in Q1 2021. As at December 31, 2021, there is no DOJ liability outstanding. The remaining liability outstanding as at December 31, 2020, of US$3,976,000 was included in current provisions and other liabilities.

Other matters

The Group recognizes a liability for legal contingencies when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss. The Group reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. To the extent new information is obtained and the Group's views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in the Group's liability accrual would be recorded in the period in which such determination is made. At December 31, 2021 the Group had recognized liabilities of US$6,000,000 in relation to ongoing legal matters (2020: US$6,000,000). At December 31, 2020, the Group had recognized liabilities of $6,000,000 in relation to ongoing legal matters as well as a non-current liability of US$21,382,000 for revenue rebates due on metreleptin sales in a country in the EMEA region following on from agreeing a reimbursement price with the government authorities. The reimbursement agreement, which was agreed in March 2021, results in a one-off revenue rebate payment on sales up to the date of approval. The one-off payment is due to be paid to the authorities in July 2022 and this is included within accrued expenses, see Note 15, Trade and other payables.

The Group has a liability, included in accrued expenses above, for revenue rebates due on Myalepta sales in a country in the EMEA region from agreeing a reimbursement price with the government authorities resulting in a one-off payment related to sales up to the date of approval, which occurred in March 2021. The Group has recognized a liability of US$21,348,000 as at December 31, 2021. At December 31, 2020 the liability was included in provisions as the underlying agreement was not finalized and it was recognized as a non-current liability for an amount of US$21,382,000 as payment was agreed to be made in July 2022. Other accruals mainly consist of costs related to government revenue rebates due within one year, convertible note interest, term loan interest, royalty expenses, restructuring costs, clinical and R&D activities.

Net	(277,456)	(305,046)

Financial instruments evaluated at fair value can be classified according to the following valuation hierarchy, which reflects the extent to which the fair value is observable:

Level 1: fair value evaluations using prices listed on active markets (not adjusted) of identical assets or liabilities.
Level 2: fair value evaluations using input data for the asset or liability that are either directly observable (as prices) or indirectly observable (derived from prices), but which do not constitute listed prices pursuant to Level 1.
Level 3: fair value evaluations using input data for the asset or liability that are not based on observable market data (unobservable input data).

The contingent consideration has been valued using Level 3. The contingent consideration comprises:

Contingent consideration relating to the acquisition of Amryt GmbH (see Note 5, Business combinations and asset acquisitions) that was measured at US$52,989,000 as at December 31, 2021 (December 31, 2020: US$86,906,000). The fair value comprises royalty payments which was determined using probability weighted revenue forecasts and the fair value of the milestones payments which was determined using probability adjusted present values. It also included a revision to the discount rate used, and revenue and costs forecasts have been amended to reflect management's current expectations.

Impact of key unobservable input data on the contingent consideration:

An increase of 10% in estimated revenue forecasts would result in an increase to the fair value of US$3,359,000. A decrease would have the opposite effect.
A 5% increase in the discount factor used would result in a decrease to the fair value of US$8,826,000. A decrease of 5% would result in an increase to the fair value of US$11,696,000.
A six-month delay in the launch date for Oleogel-S10 would result in a decrease to the fair value of US$4,770,000.
A 20% increase in the probability of success used would result in an increase to the fair value of US$17,660,000. A decrease would have the opposite effect.

17. Events after the reporting period

Development Pipeline

As noted above, Amryt received a Complete Response Letter from the (FDA) regarding its (NDA) for Oleogel-S10, for the treatment of the cutaneous manifestations of EB, a rare, genetic skin disease characterized by extremely fragile skin that blisters and tears from minor friction or trauma for which there are no approved treatment options.

The FDA communicated that it had completed its review of the application and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB. Amryt intends to discuss with the FDA the nature of the data required to address the Agency's concerns.

On March 8, 2022, Amryt announces the completion of a successful pharmacokinetic (PK) study for Mycapssa® (oral octreotide). The data supports a planned Phase 3 study of Mycapssa® in the treatment of patients with carcinoid symptoms due to Neuroendocrine Tumors (NET).

Debt refinancing

On February 22, 2022, Amryt announced that it secured US$125,000,000 of senior credit facilities from funds managed by the Credit Group of Ares Management Corporation ("Ares"). Amryt used a portion of the proceeds to refinance its previous secured term debt facility, which has an outstanding balance of US$93,988,000 as at February 22, 2022, an interest rate of 13.00% and a maturity date of September 2024. The new facilities will generate significant annual interest cost savings as well as provide for important strategic flexibility as Amryt looks to continue to grow its global rare disease presence.

Key features of the new facilities include:

Total new facilities of $125 million, consisting of:
- $85 million Term Loan Facility with interest rate of Secured Overnight Financing Rate ("SOFR")+6.75%, subject to a 0.90% SOFR floor
- $40 million Revolving Credit Facility with $20 million drawn at close and interest rate of SOFR+4.00%, subject to a 0.90% SOFR floor
- Quarterly blended cash interest rate of SOFR+5.87% (assuming fully drawn), subject to a 0.90% SOFR floor, substantially lower than Amryt's current secured term debt facility at 13.00% interest
Requires interest-only payments until facility matures in February 2027
There are no warrants or any equity conversion features associated with the new facilities
The proceeds will be used to refinance existing debt, for general corporate and product development purposes; and potentially for shareholder approved share repurchase programs.

Charges were taken over certain assets of the company and its material entities as guarantee and collateral for the provision of the debt.

There were no other significant events since the end of the reporting period.
