Accordingly, these statements involve estimates, assumptions, risks and uncertainties which could cause actual results to differ materially from those expressed in them.

This Quarterly Report on Form 10-Q contains forward-looking statements that are based on our management’s belief and assumptions and on information currently available to our management. These statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

•Our ability to enter into strategic partnerships for the commercialization, manufacturing and distribution of LUMRYZ in the U.S.;

•Our reliance on a single product, LUMRYZ;

•Our ability to finance our operations on acceptable terms, either through the raising of capital including the incurrence of convertible or other indebtedness, issuance of equity or royalty-based financings, or through strategic financing or commercialization partnerships;

•Competition existing today or that may arise in the future.

AVADEL PHARMACEUTICALS PLC

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share data)

NOTE 1: Summary of Significant Accounting Policies

Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. The Company is registered as an Irish public limited company. The Company’s headquarters are in Dublin, Ireland with operations in Dublin, Ireland and St. Louis, Missouri, United States (“U.S.”).

LUMRYZ is an extended-release formulation of sodium oxybate indicated to be taken once at bedtime for the treatment of cataplexy or excessive daytime sleepiness (“EDS”) in adults with narcolepsy. LUMRYZ was approved by the U.S. Food and Drug Administration (“FDA”) on May 1, 2023. The FDA also granted Orphan Drug Exclusivity (“ODE”) to LUMRYZ for a period of seven years until May 1, 2030. In June 2023, the Company commercially launched LUMRYZ in the U.S.

In approving LUMRYZ, the FDA approved a risk evaluation and mitigation strategy (“REMS”) for LUMRYZ to help ensure that the benefits of the drug in the treatment of cataplexy and EDS in narcolepsy outweigh the risks of serious adverse outcomes resulting from inappropriate prescribing, misuse, abuse, and diversion of the drug. Under this REMS, healthcare providers who prescribe the drug must be specially certified; pharmacies that dispense the drug must be specially certified; and the drug must be dispensed only to patients who have enrolled in the LUMRYZ REMS and completed all REMS requirements, including documentation of safe use conditions.

As of the date of this Quarterly Report, the Company’s only commercialized product is LUMRYZ. The Company continues to evaluate opportunities to expand its product portfolio.

Liquidity. The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

The adequacy of the Company’s cash resources depends on the outcome of certain business conditions including the cost of the Company’s ongoing LUMRYZ commercialization activities, the Company’s cost structure, and other factors set forth in “Risk Factors” within Part I, Item 1A of the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on February 29, 2024 (the “Annual Report on Form 10-K”).

Ordinary Shares

Effective April 15, 2024, the Company’s ordinary shares, nominal value $0.01 per share (“ordinary shares”), became directly listed on the Nasdaq Stock Market. The Company caused a mandatory exchange of its American Depositary Shares (“ADSs”) for the underlying ordinary shares on a one-for-one basis. Accordingly, the Bank of New York Mellon (“BNY Mellon”), as Depositary for the ADSs, issued a notice of termination of its American Depository Receipt program (“ADR Program”) of ADSs to the registered holders of ADSs according to the requirements under the deposit agreement dated January 3, 2017 (the “Deposit Agreement”) among the Company, BNY Mellon and holders of ADSs. The Deposit Agreement terminated on July 15, 2024.

At-the-Market Offering Program

On May 8, 2024, the Company entered into an Open Market Sale AgreementSM (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) pursuant to which the Company may offer and sell its ordinary shares, from time to time, with respect to an at-the-market offering program (“ATM Program”) under which Jefferies will act as sales agent. The Sales Agreement provides that Jefferies will be entitled to aggregate compensation for its services an amount up to 3.0% of the gross proceeds of any ordinary shares sold through Jefferies under the Sales Agreement. The Sales Agreement replaces the Company’s previous Open Market Sale AgreementSM with Jefferies, dated February 4, 2020 (the “ADS Sales Agreement”), which provided for the sale of ADSs by the Company. The Company terminated the ADS Sales Agreement upon effectiveness of the Sales Agreement following the mandatory exchange of the ADSs and the direct listing of the ordinary shares on the Nasdaq Stock Market on April 15, 2024.

The ordinary shares will be offered and sold pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-267198), filed with the SEC on August 31, 2022, as amended, and declared effective by the Commission on September 12, 2022, as supplemented by the prospectus supplement dated May 8, 2024 (the “Prospectus Supplement”). The Company may offer and sell ordinary shares having an aggregate offering price of up to $100,000 under the Prospectus Supplement.

- 10 -

Prior to termination, the Company issued and sold 640 ordinary shares pursuant to the ADS Sales Agreement during the three months ended March 31, 2024, resulting in net proceeds to the Company of approximately $9,250. The Company did not issue or sell ordinary shares during the three months ended June 30, 2024 under the Sales Agreement.

Preferred Shares

In March 2024, 5,194 Series A Non-Voting Convertible Preferred Shares and Series B Non-Voting Convertible Preferred Shares (“Series B Preferred Shares”) were converted to 5,194 ordinary shares at the option of the holders. Accordingly, there were no preferred shares issued and outstanding at June 30, 2024.

Basis of Presentation. The unaudited condensed consolidated balance sheet as of June 30, 2024 and the interim unaudited condensed consolidated financial statements presented herein, have been prepared in accordance with U.S. GAAP, the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by U.S. GAAP for complete financial statements or all the disclosures normally made in an Annual Report on Form 10-K. Accordingly, the unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Annual Report on Form 10-K.

Certain prior year amounts have been reclassified within the notes to the unaudited condensed consolidated financial statements to condense line items of the same nature to conform with the current year presentation.

The unaudited condensed consolidated financial statements include the accounts of the Company and subsidiaries and reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the dates and periods presented. All intercompany accounts and transactions have been eliminated. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period.

In March 2024, the SEC issued a final rule requiring public companies to disclose climate-related information in their registration statements and annual reports. For large accelerated filers, the initial disclosure rules are effective for annual periods for the year ending December 31, 2025. In April 2024, the SEC voluntarily stayed the final rule pending the completion of judicial review by the Court of Appeals for the Eighth Circuit. The Company is monitoring the development of litigation related to the SEC’s rule, and is currently evaluating the effects of the final rule on its disclosures, processes and procedures.

NOTE 2: Revenue Recognition

The Company’s source of net product revenue during the three and six months ended June 30, 2024 and 2023 consists solely of sales of LUMRYZ in the U.S.

For the three and six months ended June 30, 2024 and 2023, three customers accounted for 100% of sales. The following table presents a summary of the percentage of total gross sales to customers:


	Three Months Ended June 30,				Six Months Ended June 30,
Sales by Customer:	2024		2023		2024		2023

Caremark	52	%	42	%	48	%	42	%
Accredo	33	%	39	%	36	%	39	%
Optum	15	%	19	%	16	%	19	%

NOTE 3: Fair Value Measurement

The Company is required to measure certain assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. For example, the Company uses fair value extensively when accounting for and reporting certain financial instruments. Fair value is estimated by applying the hierarchy described below, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement.

- 11 -

ASC 820, Fair Value Measurement, defines fair value as a market-based measurement that should be determined based on the assumptions that marketplace participants would use in pricing an asset or liability. When estimating fair value, depending on the nature and complexity of the asset or liability, the Company may generally use one or each of the following techniques:

•Income approach, which is based on the present value of a future stream of net cash flows.

•Market approach, which is based on market prices and other information from market transactions involving identical or comparable assets or liabilities.

As a basis for considering the assumptions used in these techniques, the standard establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

•Level 1 - Quoted prices for identical assets or liabilities in active markets.

•Level 2 - Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are directly or indirectly observable, or inputs that are derived principally from, or corroborated by, observable market data by correlation or other means.

•Level 3 - Unobservable inputs that reflect estimates and assumptions.

The following table summarizes the financial instruments measured at fair value on a recurring basis classified in the fair value hierarchy (Level 1, 2 or 3) based on the inputs used for valuation in the accompanying unaudited condensed consolidated balance sheets:


	As of June 30, 2024						As of December 31, 2023
Fair Value Measurements:	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3

Marketable securities (see Note 4)


Government securities - U.S.	$	42,535	$	—	$	—	$	73,944	$	—	$	—

Total assets	$	42,535	$	—	$	—	$	73,944	$	—	$	—

A review of fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification for certain financial assets or liabilities. During the periods ended June 30, 2024 and December 31, 2023, respectively, there were no transfers in and out of Level 3. During the three and six months ended June 30, 2024 and 2023, respectively, the Company did not recognize any allowances for credit losses.

Some of the Company’s financial instruments, such as cash and cash equivalents, accounts receivable and accounts payable, are reflected in the balance sheet at carrying value, which approximates fair value due to their short-term nature.

Royalty Financing Obligation

As of June 30, 2024, the carrying value of the royalty financing obligation under the Royalty Purchase Agreement (“RPA”) approximated its fair value and was measured using the estimates of forecasted net product revenue based on current contractual and statutory requirements, specific known market events and trends, industry data, historical trends, current and expected patient demand and forecasted customer buying and payment patterns (Level 3 inputs). See Note 6: Royalty Financing Obligation for additional information regarding the Company’s royalty financing obligation.

NOTE 4: Marketable Securities

The Company has investments in available-for-sale debt securities which are recorded at fair market value. The change in the fair value of available-for-sale debt investments is recorded as accumulated other comprehensive loss in shareholders’ equity, net of income tax effects. As of June 30, 2024, the Company considered any decreases in fair value on its marketable securities to be driven by factors other than credit risk, including market risk.

The following tables show the Company’s available-for-sale securities’ adjusted cost, gross unrealized gains, gross unrealized losses and fair value by significant investment category as of June 30, 2024 and December 31, 2023, respectively:

- 12 -


	June 30, 2024
Marketable Securities:	Adjusted Cost		Unrealized Gains		Unrealized Losses		Fair Value



Government securities - U.S.	$	42,320	$	215	$	—	$	42,535

Total	$	42,320	$	215	$	—	$	42,535


	December 31, 2023
Marketable Securities:	Adjusted Cost		Unrealized Gains		Unrealized Losses		Fair Value



Government securities - U.S.	$	72,990	$	954	$	—	$	73,944

Total	$	72,990	$	954	$	—	$	73,944

The Company determines realized gains or losses on the sale of marketable securities on a specific identification method. The Company reflects these gains and losses as a component of investment and other income, net in the accompanying unaudited condensed consolidated statements of loss.

The Company recognized gross realized gains of $709 and no gross realized losses for the three months ended June 30, 2024. The Company recognized gross realized gains of $1,107 and no gross realized losses for the six months ended June 30, 2024. The Company recognized immaterial gross realized gains and losses for the three and six months ended June 30, 2023.

The following table summarizes the estimated fair value of the Company’s investments in marketable debt securities, accounted for as available-for-sale debt securities and classified by the contractual maturity date of the securities as of June 30, 2024:


	Maturities
Marketable Debt Securities:	Less than 1 Year		1-5 Years		5-10 Years		Greater than 10 Years		Total


Government securities - U.S.	$	42,535	$	—	$	—	$	—	$	42,535


Total	$	42,535	$	—	$	—	$	—	$	42,535

The Company has classified its investment in available-for-sale marketable debt securities as current assets in the condensed consolidated balance sheets as the securities need to be available for use, if required, to fund current operations. There are no restrictions on the sale of any securities in the Company’s investment portfolio.

NOTE 5: Inventories

The principal categories of inventories were comprised of the following:


Inventory:	June 30, 2024		December 31, 2023

Raw materials and supplies	$	2,566	$	5,291
Work in process	4,819		2,037
Finished goods	5,928		3,052
Total	$	13,313	$	10,380

The Company capitalizes inventory costs associated with products when future commercialization is considered probable and the future economic benefit is expected to be realized, which is typically when regulatory approval is obtained for a drug candidate. As such, the Company began capitalizing costs related to inventory in May 2023 upon FDA approval of LUMRYZ. Manufacturing costs associated with inventory purchased or produced prior to FDA approval were recorded as research and development expense in prior periods.

NOTE 6: Royalty Financing Obligation

On March 29, 2023, the Company and Avadel CNS Pharmaceuticals, LLC entered into the RPA with RTW Investments, L.P. (“RTW”) that could provide the Company up to $75,000 of royalty financing in two tranches. The first tranche of $30,000 became available upon satisfaction of certain conditions which included the Company’s first shipment of LUMRYZ. The second tranche is now available to use, at the Company’s election, as the Company has achieved quarterly net revenue of

- 13 -

$25,000 prior to the quarter ending June 30, 2024. The second tranche expires if the Company does not elect to use it by August 31, 2024.

On August 1, 2023, the Company received the first tranche of $30,000. As a result of receiving the first tranche, the Company is required to make quarterly royalty payments calculated as 3.75% of worldwide net product revenue of LUMRYZ, up to a total payback of $75,000.

The RPA is recorded as a royalty financing obligation on the unaudited condensed consolidated balance sheets based on the Company’s evaluation of the terms of the RPA. The accounts receivable and inventory balances of LUMRYZ are pledged as collateral for the RPA. There are no subjective acceleration clauses or provisions, and there are no covenants in violation or other clauses that would cause the full amount of the royalty financing obligation to be callable. As such, the RPA is recorded as a long-term obligation on the unaudited condensed consolidated balance sheets.

The Company imputes interest using the effective interest method and records interest expense based on the unamortized royalty financing obligation. The Company’s estimate of the interest rate under the RPA is based primarily on forecasted net revenue and the calculated amounts and timing of net royalty payments to reach the total payback of $75,000. As of June 30, 2024 and December 31, 2023 the effective interest rate is estimated as 30.4%. The Company will account for changes in the imputed interest rate resulting from changes in forecasted net product revenue using the prospective method.

The following table shows the activity within the royalty financing obligation account:


Royalty Financing Obligation:	June 30, 2024		December 31, 2023
Royalty financing obligation – beginning balance	$	33,490	$	—
Receipt of the first tranche of the royalty financing obligation	—		30,000
Accretion of imputed interest expense on royalty financing obligation	5,308		3,743
Less: royalty payments made to RTW	(1,748)		(253)
Royalty financing obligation – ending balance	37,050		33,490
Less: royalty payable to RTW classified within accrued expenses	(1,557)		(730)
Royalty financing obligation, non-current	$	35,493	$	32,760

The accretion of imputed interest expense is reflected as interest expense in the unaudited condensed consolidated statements of loss. For the three months ended June 30, 2024, the total interest expense related to the royalty financing obligation was $2,716. For the six months ended June 30, 2024, the total interest expense related to the royalty financing obligation was $5,308.

NOTE 7: Income Taxes

The income tax benefit was $509 for the three months ended June 30, 2024 resulting in an effective tax rate of 3.6%. The income tax provision was $90 for the three months ended June 30, 2023 resulting in an effective tax rate of (0.1)%. The change in the effective income tax rate for the three months ended June 30, 2024, as compared to the prior period in 2023, is primarily driven by the release of uncertain tax positions due to the expiration of their statute of limitations in the current period.

The income tax benefit was $416 for the six months ended June 30, 2024 resulting in an effective tax rate of 1.0%. The income tax benefit was $490 for the six months ended June 30, 2023 resulting in an effective tax rate of 0.5%. The change in the effective income tax rate for the six months ended June 30, 2024, as compared to the prior period in 2023, is primarily driven by the release of uncertain tax positions due to the expiration of their statute of limitations in the current period compared to a state tax refund received during the first quarter of the prior period.

The Company's cumulative loss position was significant negative evidence in assessing the need for a valuation allowance on its deferred tax assets. Given the weight of objectively verifiable historical losses from operations, the Company has a full valuation allowance on its deferred tax assets. The Company will be able to reverse the valuation allowance when it has shown its ability to generate taxable income on a consistent basis in future periods. The valuation allowance does not have an impact on the Company's ability to utilize any net operating losses or other tax attributes to offset cash taxes payable as these items are still eligible to be used.

NOTE 8: Other Assets and Liabilities

Various other assets and liabilities are summarized as follows:

- 14 -


Prepaid Expenses and Other Current Assets:	June 30, 2024		December 31, 2023

Prepaid and other expenses	$	6,109	$	4,373

Tax liabilities	$	4,985	$	5,407
Other	834		247
Total	$	5,819	$	5,654

NOTE 9: Net Loss Per Share

Basic net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding during each period. Diluted net loss per share is calculated by dividing net loss by the diluted number of shares outstanding during each period. Except where the result would be anti-dilutive to net loss, diluted net loss per share would be calculated assuming the impact of the conversion of the 4.50% exchangeable senior notes due February 2023 (“February 2023 Notes”) and the 4.50% exchangeable senior notes due October 2023 (“October 2023 Notes”, together, the “2023 Notes”), the conversion of the Company’s preferred shares, the exercise of outstanding equity compensation awards, and ordinary shares expected to be issued under the Company’s Employee Share Purchase Plan (“ESPP”).

The Company had a choice to settle the conversion obligations under the 2023 Notes in cash, shares or any combination of the two. The Company utilized the if-converted method to reflect the impact of the conversion of the 2023 Notes, unless the result was anti-dilutive. This method assumed the conversion of the 2023 Notes into shares of the Company’s ordinary shares and reflected the elimination of the interest expense related to the 2023 Notes.

The dilutive effect of the stock options, restricted stock units, preferred shares and ordinary shares expected to be issued under the Company’s ESPP has been calculated using the treasury stock method.

- 15 -

A reconciliation of basic and diluted net loss per share, together with the related shares outstanding in thousands is as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
Net Loss Per Share:	2024		2023		2024		2023

Net loss	$	(13,822)	$	(64,432)	$	(41,164)	$	(95,216)



Weighted average shares:
Basic shares	96,151		77,246		93,922		70,603
Effect of dilutive securities—employee and director equity awards outstanding, preferred shares and 2023 Notes	—		—		—		—

Diluted shares	96,151		77,246		93,922		70,603

Net loss per share - basic	$	(0.14)	$	(0.83)	$	(0.44)	$	(1.35)
Net loss per share - diluted	$	(0.14)	$	(0.83)	$	(0.44)	$	(1.35)

Potential ordinary shares of 1,140 and 2,212 were excluded from the calculation of weighted average shares for the three months ended June 30, 2024 and 2023, respectively, and 1,032 and 6,813 were excluded from the calculation of weighted average shares for the six months ended June 30, 2024 and 2023, respectively, because their effect was considered to be anti-dilutive or they were related to shares from performance share unit awards for which the contingent vesting condition had not been achieved. For the three and six months ended June 30, 2024 and 2023, the effects of dilutive securities were entirely excluded from the calculation of net loss per share as a net loss was reported in these periods.

NOTE 10: Comprehensive Loss

The following table shows the components of accumulated other comprehensive loss, net of tax effects:


	Three Months Ended June 30,				Six Months Ended June 30,
Accumulated Other Comprehensive Loss:	2024		2023		2024		2023

Foreign currency translation adjustment:
Beginning balance	$	(24,357)	$	(24,277)	$	(24,121)	$	(24,452)
Net other comprehensive (loss) income	(74)		8		(310)		183
Balance at June 30,	$	(24,431)	$	(24,269)	$	(24,431)	$	(24,269)

Unrealized gain (loss) on marketable debt securities, net
Beginning balance	$	601	$	(1,749)	$	954	$	(1,890)
Net other comprehensive (loss) income, net of income tax expense of $0, $0, $0, and $0 respectively	(385)		75		(738)		216
Balance at June 30,	$	216	$	(1,674)	$	216	$	(1,674)
Accumulated other comprehensive loss at June 30,	$	(24,215)	$	(25,943)	$	(24,215)	$	(25,943)

The effect on the Company’s unaudited condensed consolidated financial statements of amounts reclassified out of accumulated other comprehensive loss was immaterial for all periods presented.

NOTE 11: Commitments and Contingencies

Litigation

The Company is subject to potential liabilities generally incidental to its business arising out of present and future lawsuits and claims related to product liability, personal injury, contract, commercial, intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. The Company accrues for potential liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such costs can be reasonably estimated. At June 30, 2024 and December 31, 2023, there were no contingent liabilities with respect to any litigation, arbitration or administrative or other

- 16 -

proceeding that are reasonably likely to have a material adverse effect on the Company’s consolidated financial position, results of operations, cash flows or liquidity.

First Jazz Complaint

On May 12, 2021, Jazz Pharmaceuticals, Inc. (“Jazz”) filed a formal complaint (the “First Complaint”) initiating a lawsuit in the United States District Court for the District of Delaware (the “Court”) against Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Management Corporation, Avadel Legacy Pharmaceuticals, LLC, Avadel Specialty Pharmaceuticals, LLC, and Avadel CNS Pharmaceuticals, LLC (collectively, the “Avadel Parties”). In the First Complaint, Jazz alleges the sodium oxybate product (“Proposed Product”) described in the NDA owned by Avadel CNS Pharmaceuticals, LLC (“Avadel CNS”) will infringe at least one claim of U.S. Patent No. 8731963, 10758488, 10813885, 10959956 and/or 10966931 (collectively, the “patents-in-suit”). The First Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses.

On June 3, 2021, the Avadel Parties timely filed their Answer and Counterclaims (the “Avadel Answer”) with the Court in response to the First Complaint. The Avadel Answer generally denies the allegations set forth in the First Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patents-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of each patent-in-suit, and ii) a declaratory judgment of invalidity of each patent-in-suit.

On June 18, 2021, Jazz filed its Answer (“Jazz Answer”) with the Court in response to the Avadel Answer. The Jazz Answer generally denies the allegations set forth in the Avadel Answer and sets forth a single affirmative defense asserting that Avadel has failed to state a claim for which relief can be granted.

On June 21, 2021, the Court issued an oral order requiring the parties to i) confer regarding proposed dates to be included in the Court’s scheduling order for the case, and ii) submit a proposed order, including a proposal for the length and timing of trial, to the Court by no later than July 21, 2021.

On July 30, 2021, the Court issued a scheduling order establishing timing for litigation events including i) a claim construction hearing date of August 2, 2022, and ii) a trial date of October 30, 2023.

On October 18, 2021, consistent with the scheduling order, Jazz filed a status update with the Court indicating that Jazz did not intend to file a preliminary injunction with the Court at this time. Jazz further indicated that it would provide the Court with an update regarding whether preliminary injunction proceedings may be necessary after receiving further information regarding the FDA’s action on Avadel CNS’s NDA.

On January 4, 2022, the Court entered an agreed order dismissing this case with respect to Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Specialty Pharmaceuticals, LLC, Avadel Legacy Pharmaceuticals, LLC, and Avadel Management Corporation. A corresponding order was entered in the two below cases on the same day.

On February 25, 2022, Jazz filed an amended Answer to the Avadel Parties’ Counterclaims (“the Jazz First Amended Answer”). The Jazz First Amended Answer is substantially similar to the Jazz Answer except insofar as it adds an affirmative defense for judicial estoppel and unclean hands. Corresponding amended answers were filed in the two below cases on the same day.

On June 23, 2022, Avadel CNS filed a Renewed Motion for Judgment on the Pleadings, with respect to its counterclaim against Jazz seeking to have U.S. Patent No. 8731963 (the “REMS Patent”) delisted from the Orange Book and seeking to have the motion resolved concurrent with the parties’ Markman hearing on August 31, 2022. On July 7, 2022, Jazz filed a response styled as Objections to Avadel CNS’ Motion for Judgment on the Pleadings. On July 14, 2022, Avadel CNS replied to Jazz’s response, and on July 21, 2022, Avadel CNS requested oral argument on its delisting motion simultaneous with the Markman hearing. On August 24, 2022, the Court ordered Jazz to respond substantively to Avadel CNS’ motion, which Jazz did on August 26, 2022. Avadel CNS filed its reply on August 28, 2022.

On August 23, 2022, the Markman hearing was postponed. On September 7, 2022, the case was reassigned to a new judge, and the Markman hearing was held on October 25, 2022. At the Markman hearing, Avadel CNS reiterated its request for an expedited hearing on the Renewed Motion for Judgment on the Pleadings for the delisting of the REMS Patent. On October 28, 2022, the Court granted Avadel CNS’ request and scheduled the hearing for November 15, 2022.

- 17 -

The Court held the Markman hearing on November 15, 2022 and issued a claim construction ruling on November 18, 2022. Also, on November 18, 2022 the Court granted Avadel’s Renewed Motion for Judgment on the Pleadings and ordered Jazz to request delisting of the REMS Patent from the Orange Book. On November 22, 2022, Jazz appealed that decision and on December 14, 2022, the Federal Circuit issued a stay of the delisting order until further notice. Oral argument was held February 14, 2023. On February 24, 2023, the United States Court of Appeals for the Federal Court affirmed the previous ruling from the Court, ordering the delisting of the REMS Patent from the Orange Book, which has since occurred. On March 7, 2023, in response to a joint stipulation filed by the parties, the Court issued an order dismissing Jazz’s infringement claims against the Avadel Parties relating to the REMS Patent as well as Avadel Parties’ noninfringement and invalidity counterclaims relating to the REMS Patent.

On March 15, 2023, the parties submitted a Stipulation and Proposed Order Modifying the Case Schedule to accommodate additional claim construction proceedings. That stipulation remains pending before the Court. On April 26, 2023, the parties filed their Supplemental Joint Claim Construction Brief.

On July 3, 2023, the Court issued a modified scheduling order establishing a new trial date of February 26, 2024.

On July 21, 2023, in response to a Court order, the parties submitted a Stipulation and Proposed Order Modifying the Case Schedule with an updated proposed schedule to accommodate additional claim construction proceedings. On August 4, 2023, the Court entered a modified version of the parties’ proposed schedule, which was revised on August 28, 2023. The parties’ Second Supplemental Joint Claim Construction Brief was filed on October 10, 2023, and a Markman hearing regarding the disputed terms occurred on November 1, 2023. The Court issued its claim construction order on December 15, 2023.

On August 15, 2023, Avadel renewed its request to consolidate this litigation with the litigation described in the Avadel Complaint below. On November 3, 2023, the Court denied that request.

On November 30, 2023, the parties filed cross motions for summary judgment. The parties filed opposition briefs on December 15, 2023. The parties filed reply briefs on December 22, 2023. On February 14, 2024, the Court denied the parties’ summary judgment motions. On February 15, 2024, the Court held its Pretrial Conference. Trial was held from February 26, 2024 to March 1, 2024 (the “February Patent Trial”). On March 4, 2024, the jury returned a verdict of no infringement for U.S. Patent No. 10758488 and infringement of U.S. Patent No. 11147782, with damages of $234, which are included in the unaudited condensed consolidated balance sheets in other non-current liabilities at June 30, 2024.

On March 19, 2024, the Court issued a Supplemental Scheduling Order setting a June 4, 2024 hearing on Jazz’s request for a permanent injunction or ongoing royalty. An ongoing royalty, if any, will be determined by the Court, and a range of possible loss, if any, cannot be reasonably estimated at this time. Briefing on Jazz’s request closed on May 20, 2024, and the hearing was held June 4, 2024. Jazz’s request remains pending.

Second Jazz Complaint

On August 4, 2021, Jazz filed another formal complaint (the “Second Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Second Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of U.S. Patent No. 11077079. The Second Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses.

On September 9, 2021, the Avadel Parties timely filed their Answer and Counterclaims (the “Second Avadel Answer”) with the Court in response to the Second Complaint. The Second Avadel Answer generally denies the allegations set forth in the Second Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity of the patent-in-suit.

On October 22, 2021, the Court issued an oral order stating that this case should proceed on the same schedule as the case filed on May 12, 2021.

On September 7, 2022, the case was reassigned to a new judge.

Third Jazz Complaint

On November 10, 2021, Jazz filed another formal complaint (the “Third Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Third Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of U.S. Patent No. 11147782. The Third Complaint further includes typical relief requests such

- 18 -

as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. This case will proceed on the same schedule as the cases associated with the First and Second Complaints above.

On December 21, 2021, the Court entered a revised schedule for the First, Second and Third Complaints, setting a new claim construction date of August 31, 2022.

On January 7, 2022, Avadel CNS timely filed its Answer and Counterclaims (the “Third Avadel Answer”) with the Court in response to the Third Complaint. The Third Avadel Answer generally denies the allegations set forth in the Third Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity/unenforceability of the patent-in-suit.

On September 7, 2022, the case was reassigned to a new judge.

Fourth Jazz Complaint

On July 15, 2022, Jazz filed another formal complaint (the “Fourth Complaint”) initiating a lawsuit in the Court against Avadel CNS. In the Fourth Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of the REMS Patent, which was asserted in the First Complaint. The FDA required Avadel CNS to file a Paragraph IV certification against the REMS Patent, which Avadel CNS did under protest, consistent with its Renewed Motion for Judgment on the Pleadings for the delisting of the REMS Patent from the Orange Book, which was later ordered to be delisted in the above First Jazz Complaint action. Avadel CNS provided the required notice of its Paragraph IV certification to Jazz, and Jazz reasserted the REMS Patent in a separate action following receipt of that notice. The Fourth Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses.

On September 7, 2022, the case was reassigned to a new judge.

On September 21, 2022, Jazz served the Fourth Complaint. On October 21, 2022, Avadel CNS timely filed its Answer and Counterclaims (the “Fourth Avadel Answer”) with the Court in response to the Fourth Complaint. The Fourth Avadel Answer generally denies the allegations set forth in the Fourth Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims for i) a declaratory judgment of non-infringement of the patent-in-suit, ii) a declaratory judgment of invalidity/unenforceability of the patent-in-suit, iii) delisting of the patent-in-suit from the Orange Book; iv) monopolization under the Sherman Antitrust Act of 1890 (the “Sherman Act”); and v) attempted monopolization under the Sherman Act.

On December 9, 2022, Jazz filed a Motion to Dismiss Avadel’s Antitrust Counterclaims. Avadel filed its opposition brief on December 27, 2022, and Jazz filed its reply brief on January 6, 2022. On January 11, 2023, Avadel filed a request for oral argument on the motion. On May 24, 2024, the Court denied Jazz’s Motions to Dismiss. On June 7, 2024, Jazz filed its Answer to Avadel’s Counterclaims.

On May 19, 2023, the Court issued a scheduling order establishing timing for litigation events including i) completion of fact discovery by March 14, 2024, and ii) a deadline for case dispositive motions of September 20, 2024. On January 23, 2024, the parties submitted a stipulation to extend the case schedule. On January 24, 2024, the Court ordered an extension of the case schedule, including i) completion of fact discovery by June 20, 2024 and ii) a deadline for case dispositive motions by January 31, 2025. On January 24, 2024, the Court issued an order setting a pretrial conference for October 30, 2025 and a 5-day trial to begin on November 3, 2025. On April 22, 2024, the parties submitted a stipulation extending certain pretrial deadlines, including i) extending completion of fact discovery to September 27, 2024 and ii) extending the deadline for case dispositive motions to April 4, 2025.

On June 29, 2023, Jazz filed a Motion to Stay the case, pending resolution of its Motion to Dismiss. Briefing on that Motion to Stay closed on August 10, 2023. On March 13, 2024, Jazz filed a Supplemental Motion to Stay, pending the resolution of the post-trial briefing and any appeals from the February Patent Trial. On May 24, 2024, the Court denied Jazz’s Motions to Stay. On June 7, 2024, Jazz filed a Motion for Reargument or in the Alternative to Certify an Appeal. Avadel filed its opposition brief on June 28, 2024. Jazz filed its reply brief on July 12, 2024. Jazz’s motion remains pending.

Overview

General Overview

Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. LUMRYZ is an extended-release formulation of sodium oxybate indicated to be taken once at bedtime for the treatment of cataplexy or EDS in adults with narcolepsy.

As of the date of this Quarterly Report, LUMRYZ is the only commercialized product in our portfolio. We continue to evaluate opportunities to expand our product portfolio.

LUMRYZ

LUMRYZ was approved by the FDA on May 1, 2023 for the treatment of cataplexy or EDS in adults with narcolepsy. In approving LUMRYZ, the FDA required a REMS for LUMRYZ to help ensure that the benefits of the drug in the treatment of cataplexy and EDS in adults with narcolepsy outweigh the risks of serious adverse outcomes resulting from inappropriate prescribing, misuse, abuse, and diversion of the drug. Under this REMS, healthcare providers who prescribe the drug must be specially certified; pharmacies that dispense the drug must be specially certified; and the drug must be dispensed only to patients who have enrolled in the LUMRYZ REMS and completed all REMS requirements, including documentation of safe use conditions. Additionally, with its approval, the FDA also granted seven years of orphan drug exclusivity to LUMRYZ for the treatment of cataplexy or EDS in adults with narcolepsy due to a finding of clinical superiority of LUMRYZ relative to currently marketed oxybate treatments. In particular, the FDA found that LUMRYZ makes a major contribution to patient care over currently marketed, twice-nightly oxybate treatments by providing a once-nightly dosing regimen that avoids nocturnal arousal to take a second dose. The orphan exclusivity will continue until May 1, 2030. In June 2023, we announced the U.S. commercial launch of LUMRYZ for the treatment of cataplexy or EDS in adults living with narcolepsy.

Numerous LUMRYZ-related U.S. patents have been issued having expiration dates spanning from mid-2037 to early-2042, and there are additional patent applications currently in development and/or pending at the U.S. Patent and Trademark Office (“USPTO”), as well as foreign patent offices. We currently have numerous Orange Book listed patents.

We submitted a Supplemental New Drug Application (“sNDA”) for LUMRYZ in the pediatric narcolepsy population in November 2023. The sNDA was accepted by the FDA in January 2024 and an approval decision is expected in September 2024.

With respect to clinical data generated for LUMRYZ, we conducted a Phase 3 clinical trial of LUMRYZ (the “REST-ON trial”), which was a randomized, double-blind, placebo-controlled study that enrolled 212 patients who received at least one dose of LUMRYZ or placebo, and was conducted in clinical sites in the U.S., Canada, Western Europe and Australia. Positive top line data from the REST-ON trial were announced on April 27, 2020.

- 22 -

Additionally, our open-label extension/switch study of LUMRYZ (“RESTORE”) examined the long-term safety and maintenance of efficacy of LUMRYZ in patients with narcolepsy who participated in the REST-ON trial, as well as dosing and preference data for patients who switched from twice-nightly sodium oxybate to once-at-bedtime LUMRYZ, regardless of whether they participated in the REST-ON trial. In May 2021, inclusion criteria were expanded to allow for oxybate naïve patients to enter the study. An interim safety analysis from the ongoing RESTORE study showed that LUMRYZ has generally been well-tolerated, with some patients receiving therapy for more than 18 months. In addition, interim data from RESTORE were presented demonstrating that a high proportion of patients switching from twice-nightly oxybate formulations had difficulty in taking the second dose, with a high proportion (92.5%) stating a preference for the once-at-bedtime dosing regimen and that most participants switching from twice-nightly oxybate formulations had a stable dose equal to their starting dose. Subsequent interim data showed a preference (94.0%) for the once-at-bedtime dosing regimen. The last patient visit occurred in October 2023.

A discrete choice experiment (“DCE”) showed that once-at-bedtime dosing, when compared to twice-nightly dosing, was the most important attribute driving both patient and clinician preference for overall oxybate product choice, as well as patient quality of life and reduction of patient anxiety/stress; dosing frequency (twice-nightly versus once-at-bedtime) was also viewed as a more important attribute as compared to other attributes assessed, including sodium content. Accompanying the DCE was a background survey for both patients and clinicians, which showed that dosing frequency was noted as a significant stressor by both patients and clinicians.

Additional peer-reviewed publications have included data on improvement on disturbed nocturnal sleep (“DNS”), the first DCE and a Plain Language Summary reviewing sodium oxybate and cardiovascular health, which did not identify a signal of cardiovascular disease in the over twenty years that sodium oxybate has been available.

A second DCE among clinicians was published in May 2023, showing the dosing regimen was the most important driver of choice, with once-nightly preferred. Post-hoc analyses of narcolepsy Type 1 (“NT1”) and Type 2 (“NT2”) were also published, demonstrating consistent improvements regardless of narcolepsy type. A third plain language summary has been published; most recently evaluated the improvements of LUMRYZ on DNS.

At the 2024 SLEEP meeting, Avadel presented 11 posters, including 6 post-hoc analyses from the REST-ON trial, evaluating efficacy as a function of age and gender. New data were presented from the RESTORE end-of-study questionnaire, showing the positive impact that LUMRYZ had for participants switching from twice-nightly oxybates, as well as in vitro data showing comparable drug dissolution with diluents other than water for mixing, and a human factors study demonstrating that patients can reliably follow the Instructions for Use. A discrete choice experiment among caregivers of patients with narcolepsy showed preference for once-nightly dosing as a primary driver of treatment choice and a social listening analysis underscored the myriad challenges that people with narcolepsy face.

We believe LUMRYZ has the potential to demonstrate improved dosing compliance, safety, and patient satisfaction over other treatment options for cataplexy or EDS in patients with narcolepsy.

Avadel has initiated a Phase 3 pivotal trial in Idiopathic Hypersomnia (“IH”), REVITALYZ, which is a double-blind, placebo-controlled, randomized withdrawal, multicenter Phase 3 study designed to evaluate the efficacy and safety of LUMRYZ given as a once-at-bedtime dose, in IH. The study will enroll approximately 150 adults who are diagnosed with IH and includes an open label extension portion.

The primary objective of REVITALYZ is to demonstrate reduction in daytime sleepiness as measured by the primary endpoint, change in total score of the Epworth Sleepiness Scale at Week 14. Secondary endpoints will evaluate the effect of LUMRYZ on additional efficacy parameters including patient and clinician impression of change, idiopathic hypersomnia severity, and a measure of the functional outcomes of sleep.

Key Business Trends and Highlights

In operating our business and monitoring our performance, we consider a number of performance measures, as well as trends affecting our industry as a whole, which include the following:

•Healthcare and Regulatory Reform: Various health care reform laws in the U.S. may impact our ability to successfully commercialize our products and technologies. The success of our commercialization efforts may depend on the extent to which the government health administration authorities, the health insurance funds in the E.U. Member States, private health insurers and other third-party payers in the U.S. will reimburse consumers for the cost of healthcare products and services.

•Competition and Technological Change: Competition in the pharmaceutical and biotechnology industry continues to be intense and is expected to increase. We compete with academic laboratories, research institutions, universities, joint ventures, and other pharmaceutical and biotechnology companies, including other companies developing niche branded or generic specialty pharmaceutical products or drug delivery platforms. Furthermore, major technological changes can happen quickly in the pharmaceutical and biotechnology industries. Such rapid technological change, or the development by our competitors of technologically improved or differentiated products, could render our products, product candidates, or drug delivery platforms obsolete or noncompetitive.

•Pricing Environment for Pharmaceuticals: The pricing environment continues to be in the political spotlight in the U.S. As a result, the need to obtain and maintain appropriate pricing for pharmaceutical products may become more challenging due to, among other things, the attention being paid to healthcare cost containment and other austerity measures in the U.S. and worldwide.

•Generics Playing a Larger Role in Healthcare: Generic pharmaceutical products will continue to play a large role in the U.S. healthcare system. LUMRYZ may face competition from manufacturers of generic twice-nightly sodium oxybate formulations. In January 2023, Hikma Pharmaceuticals plc, announced that it launched an authorized generic version of Jazz Pharmaceuticals plc’s (“Jazz”) Xyrem (sodium oxybate). In July 2023, Amneal Pharmaceuticals, Inc. announced that it launched an authorized generic version of Jazz’s Xyrem (sodium oxybate).

•Access to and Cost of Capital: Similar to other businesses in our industry and at our stage of development, we will continue to rely on external sources of capital to fund our business. The process of raising capital and the associated cost of such capital for a company of our financial profile can be difficult and potentially expensive. If the need were to arise to raise additional capital, access to that capital may be difficult, expensive and/or dilutive and, as a result, could create liquidity challenges for us.

•Continuing Net Loss from Operations: We have a recent history of generating losses from operations and expect to continue generating losses until we are able to generate revenues sufficient to generate positive cash flow from the commercialization of LUMRYZ. LUMRYZ is the only commercialized product in our portfolio, and we will incur substantial expenses to continue our commercial launch of LUMRYZ.

Financial Highlights

Highlights of our consolidated results for the three and six months ended June 30, 2024 are as follows:

•Net product revenue was $41,504 and $68,682 during the three and six months ended June 30, 2024, respectively, compared to net product revenue of $1,496 for the three and six months ended June 30, 2023. LUMRYZ was approved by the FDA on May 1, 2023 and we began shipping product to our customers in June 2023.

•Operating loss was $12,741 and $38,776 for the three and six months ended June 30, 2024, respectively, compared to operating loss of $49,541 and $77,839 for the three and six months ended June 30, 2023, respectively. Selling, general and administrative expenses increased $24,783 during the six months ended June 30, 2024 compared to the six months ended June 30, 2023, driven by increased headcount and costs associated with the commercial launch of LUMRYZ and higher legal fees. Research and development expenses decreased $934 during the six months ended June 30, 2024, compared to the six months ended June 30, 2023 due to lower pre-commercial related expenses, offset by new clinical work to evaluate the efficacy and safety of LUMRYZ given as a once-at-bedtime dose in IH.

- 24 -

•Net loss was $13,822 and $41,164 for the three and six months ended June 30, 2024, respectively, compared to net loss of $64,432 and $95,216 in the same periods last year, respectively.

•Diluted net loss per share was $0.14 and $0.44 for the three and six months ended June 30, 2024, respectively, compared to diluted net loss per share of $0.83 and $1.35 in the same periods last year, respectively.

•Cash, cash equivalents and marketable securities decreased $33,729 to $71,382 at June 30, 2024 from $105,111 at December 31, 2023. The decrease in cash during the six months ended June 30, 2024 was driven primarily by net cash used in operating activities of $47,890, offset by net proceeds of $9,250 from the sale of ADSs under the ADS Sales Agreement $4,663 of proceeds from stock option exercises and employee share purchase plan issuances.

Critical Accounting Estimates

Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. To prepare these financial statements, management makes estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosures of contingent assets and liabilities. Actual results could be significantly different from these estimates.

Our significant accounting policies are described in Note 1 of the audited consolidated financial statements included in our Annual Report on Form 10-K. The SEC suggests companies provide additional disclosure on those accounting policies considered most critical. The SEC considers an accounting policy to be critical if it is important to our financial condition and results of operations and requires significant judgments and estimates on the part of management in its application. Our estimates are often based on complex judgments, probabilities and assumptions that management believes to be reasonable, but that are inherently uncertain and unpredictable. It is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. For a complete discussion of our critical accounting policies, see the “Critical Accounting Estimates” section of the Management’s Discussion & Analysis in our Annual Report on Form 10-K filed with the SEC on February 29, 2024.

Research and Development Expenses:	2024		2023		$		%

Research and development expense	$	7,119	$	8,053	$	(934)	(11.6)	%

Research and development expenses decreased $934 or 11.6% during the six months ended June 30, 2024 as compared to the same period in the prior year. This decrease was driven by lower pre-commercial related expenses of $3,600, offset by new clinical work during the period of $2,000 and higher compensation costs of $700 due to increased headcount.



	Six Months Ended June 30,				Change
					2024 vs. 2023
Selling, General and Administrative Expenses:	2024		2023		$		%

Selling, general and administrative expenses	$	96,029	$	71,246	$	24,783	34.8	%

Selling, general and administrative expenses increased $24,783 or 34.8% during the six months ended June 30, 2024 as compared to the same period in the prior year. This increase was driven by higher compensation costs of $10,400 due to increased headcount, higher costs associated with the commercial launch of LUMRYZ of $8,900, and higher legal fees of $1,800, offset by $1,300 of costs related to financing activities incurred in 2023 that did not recur in the current period. The increase in selling, general and administrative expense for the six months ended June 30, 2024 also includes $5,500 of nonrecurring fees associated with terminating our ADSs.

Investment and Other Income, net:	2024		2023		$		%

Investment and other income, net	$	2,504	$	816	$	1,688	206.9	%

Investment and other income, net increased $1,688 or 206.9% during the six months ended June 30, 2024 as compared to the same period in the prior year. This increase was driven by higher net realized gains of approximately $1,200 and higher accrued interest on marketable securities of approximately $200.



	Three and Six Months Ended June 30,				Change
					2024 vs. 2023
Loss on Extinguishment of Debt:	2024		2023		$		%

Loss on extinguishment of debt	$	—	$	(13,129)	$	13,129	(100.0)	%

Over the course of April 3 and April 4, 2023, we completed an exchange of $96,188 of our $117,375 4.50% exchangeable senior notes due October 2023 (the “October 2023 Notes”) for $106,268 of a new series of 6.0% exchangeable notes due April 2027 (the “April 2027 Notes”). We accounted for the exchange of the October 2023 Notes for the April 2027 Notes as an extinguishment of $96,188 of our October 2023 Notes. We recorded a loss on the extinguishment of $13,129 as a result of the exchange. On June 26, 2023, and in accordance with the terms of the Indenture, the Company completed the Mandatory Exchange of $106,268 of aggregate principal amount of the April 2027 Notes, which represents all of the April 2027 Notes outstanding under the Indenture. See Note 10: Long-term debt of the audited consolidated financial statements included in our Annual Report on Form 10-K for further details.

Liquidity and Capital Resources

Our cash flows from operating, investing and financing activities, as reflected in the unaudited condensed consolidated statements of cash flows, are summarized in the following table:



	Six Months Ended June 30,				Change
					2024 vs. 2023
Net cash (used in) provided by:	2024		2023		$		%

Operating activities	$	(47,890)	$	(62,256)	$	14,366	23.1	%
Investing activities	31,937		(87,842)		119,779		(136.4)	%
Financing activities	13,913		125,986		(112,073)		(89.0)	%

Operating Activities

Net cash used in operating activities was $47,890 and $62,256 for the six months ended June 30, 2024 and 2023, respectively. Net cash used in operating activities for the six months ended June 30, 2024 was driven by net loss of $41,164 and unfavorable changes in working capital of $17,347, offset by favorable non-cash adjustments of $10,621 driven primarily by share-based compensation expense. For the six months ended June 30, 2023, net cash used in operating activities was driven by net loss of $95,216, offset by favorable changes in working capital of $6,974 and favorable non-cash adjustments of $25,986 due to the loss on extinguishment of debt and share-based compensation expense.

Investing Activities

Net cash provided by investing activities was $31,937 for the six months ended June 30, 2024. Net cash used in investing activities was $87,842 for the six months ended June 30, 2023. Net cash provided by investing activities for the six months ended June 30, 2024 was due to net proceeds received from the excess of sales over purchases of marketable securities of $31,937. Net cash used in investing activities for the six months ended June 30, 2023 was due to net purchases of marketable securities over proceeds received from the excess of sales of $87,842 as a result of investing the proceeds of our financing activities.

Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2024 of $13,913 was a result of net proceeds of $9,250 from the sale of ADSs under the ADS Sales Agreement and $4,663 of proceeds from stock option exercises and employee share purchase plan issuances. Net cash provided by financing activities for the six months ended June 30, 2023 of $125,986 was a result of net proceeds of $134,151 received in exchange for issuing 12,205 ordinary shares and 4,706 Series B Preferred Shares in the April 3, 2023 public offering and net proceeds from the sale of ADSs under the ADS Sales Agreement of $11,913, offset by payments for the February 2023 Notes of $17,500 and debt issuance costs of $4,357.

Risk Management

The adequacy of our cash resources depends on the outcome of certain business conditions including the cost of our ongoing LUMRYZ commercialization activities, our cost structure, and other factors set forth in “Risk Factors” within Part I, Item 1A of our Annual Report on Form 10-K filed with the SEC on February 29, 2024. We will need to commit substantial resources to support the commercialization of LUMRYZ which could result in future losses or otherwise limit our opportunities or affect our ability to operate our business. Our assumptions concerning the outcome of certain business conditions may prove to be wrong or other factors may adversely affect our business, and as a result we could exhaust or significantly decrease our available cash and marketable securities balances which could, among other things, force us to raise additional funds and/or force us to reduce our expenses, either of which could have a material adverse effect on our business. Additionally, we are unable to estimate the near or long term impacts of inflation, and rising interest rates, which may have a material adverse impact on our business.

We believe our existing cash, cash equivalents and marketable securities, along with cash anticipated from sales of LUMRYZ, provides sufficient capital to meet our operating, royalty obligation and capital requirements for the next twelve months following the date of this Quarterly Report.

Other Matters

Litigation

We are subject to potential liabilities generally incidental to our business arising out of present and future lawsuits and claims related to product liability, personal injury, contract, commercial, intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. We accrue for potential liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such costs can be reasonably estimated. At June 30, 2024 and December 31, 2023, there were no contingent liabilities with respect to any litigation, arbitration or administrative or other proceeding that are reasonably likely to have a material adverse effect on our consolidated financial position, results of operations, cash flows or liquidity. For information regarding legal proceedings we are involved in, see Note 11: Commitments and Contingencies - Litigation to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Risk

We are subject to interest rate risk as a result of our portfolio of marketable securities. The primary objectives of our investment policy are as follows: safety and preservation of principal and diversification of risk; liquidity of investments sufficient to meet cash flow requirements; and competitive yield. Although our investments are subject to market risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or certain types of investment. Our investment policy allows us to maintain a portfolio of cash equivalents and marketable securities in a variety of instruments, including U.S. federal government and federal agency securities, European Government bonds, corporate bonds or commercial paper issued by U.S. or European corporations, money market instruments, certain qualifying money market mutual funds, certain repurchase agreements, tax-exempt obligations of states, agencies, and municipalities in the U.S. and Europe, and equities. A hypothetical 50 basis point change in interest rates would not result in a material decrease or increase in the fair value of our securities due to the general short-term nature of our investment portfolio.

Foreign Exchange Risk

We are exposed to foreign currency exchange risk as the functional currency financial statements of a non-U.S. subsidiary is translated to U.S. dollars. The assets and liabilities of this non-U.S. subsidiary having a functional currency other than the U.S. dollar is translated into U.S. dollars at the exchange rate prevailing at the balance sheet date, and at the average exchange rate for the reporting period for revenue and expense accounts. The cumulative foreign currency translation adjustment is recorded as a component of accumulated other comprehensive loss in shareholders’ equity. The reported results of this non-U.S. subsidiary will be influenced by their translation into U.S. dollars by currency movements against the U.S. dollar. Our primary currency translation exposure is related to one subsidiary that has functional currencies denominated in euro. A 10% strengthening/weakening in the rates used to translate the results of our non-U.S. subsidiaries that have functional currencies denominated in euro as of June 30, 2024 would have had an immaterial impact on net loss for the three and six months ended June 30, 2024.

Transactional exposure arises where transactions occur in currencies other than the functional currency. Transactions in foreign currencies are recorded at the exchange rate prevailing at the date of the transaction. The resulting monetary assets and liabilities are translated into the appropriate functional currency at exchange rates prevailing at the balance sheet date and the resulting gains and losses are reported in investment and other income, net in the consolidated statements of loss. As of June 30, 2024, our primary exposure is to transaction risk related to euro net monetary assets and liabilities held by subsidiaries with a U.S. dollar functional currency. Realized and unrealized foreign exchange gains resulting from transactional exposure were immaterial for the three and six months ended June 30, 2024.

Inflation Risk

Inflation generally affects us by increasing our costs of labor and supplies and the costs of our third parties we rely on for the development, manufacture and supply of our products. We do not believe that inflation had a material effect on our business, financial condition or results of operations during the three and six months ended June 30, 2024. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, we may experience some effect in the near future (especially if inflation rates continue to rise) due to an impact on the costs to conduct clinical trials, the costs to commercially launch LUMRYZ, labor costs we incur to attract and retain qualified personnel, and other operational costs. Inflationary costs could adversely affect our business, financial condition and results of operations.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Management of the Company, with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of June 30, 2024, the end of the period covered by this Quarterly Report on Form 10-Q. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to provide reasonable assurance that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Based on their evaluation, as of the end of the period covered by this Quarterly Report on Form 10-Q, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of June 30, 2024.

Other Changes in Internal Controls

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rule 13a-15 or 15d-15 that occurred during the three months ended June 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 29, 2024.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. The Company is registered as an Irish public limited company. The Company’s headquarters are in Dublin, Ireland with operations in Dublin, Ireland and St. Louis, Missouri, United States (“U.S.”). LUMRYZ is an extended-release formulation of sodium oxybate indicated to be taken once at bedtime for the treatment of cataplexy or excessive daytime sleepiness (“EDS”) in adults with narcolepsy. LUMRYZ was approved by the U.S. Food and Drug Administration (“FDA”) on May 1, 2023. The FDA also granted Orphan Drug Exclusivity (“ODE”) to LUMRYZ for a period of seven years until May 1, 2030. In June 2023, the Company commercially launched LUMRYZ in the U.S. In approving LUMRYZ, the FDA approved a risk evaluation and mitigation strategy (“REMS”) for LUMRYZ to help ensure that the benefits of the drug in the treatment of cataplexy and EDS in narcolepsy outweigh the risks of serious adverse outcomes resulting from inappropriate prescribing, misuse, abuse, and diversion of the drug. Under this REMS, healthcare providers who prescribe the drug must be specially certified; pharmacies that dispense the drug must be specially certified; and the drug must be dispensed only to patients who have enrolled in the LUMRYZ REMS and completed all REMS requirements, including documentation of safe use conditions. As of the date of this Quarterly Report, the Company’s only commercialized product is LUMRYZ. The Company continues to evaluate opportunities to expand its product portfolio. Liquidity. The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The adequacy of the Company’s cash resources depends on the outcome of certain business conditions including the cost of the Company’s ongoing LUMRYZ commercialization activities, the Company’s cost structure, and other factors set forth in “Risk Factors” within Part I, Item 1A of the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on February 29, 2024 (the “Annual Report on Form 10-K”). Ordinary Shares Effective April 15, 2024, the Company’s ordinary shares, nominal value $0.01 per share (“ordinary shares”), became directly listed on the Nasdaq Stock Market. The Company caused a mandatory exchange of its American Depositary Shares (“ADSs”) for the underlying ordinary shares on a one-for-one basis. Accordingly, the Bank of New York Mellon (“BNY Mellon”), as Depositary for the ADSs, issued a notice of termination of its American Depository Receipt program (“ADR Program”) of ADSs to the registered holders of ADSs according to the requirements under the deposit agreement dated January 3, 2017 (the “Deposit Agreement”) among the Company, BNY Mellon and holders of ADSs. The Deposit Agreement terminated on July 15, 2024. At-the-Market Offering Program On May 8, 2024, the Company entered into an Open Market Sale AgreementSM (the “Sales Agreement”) with Jefferies LLC (“Jefferies”) pursuant to which the Company may offer and sell its ordinary shares, from time to time, with respect to an at-the-market offering program (“ATM Program”) under which Jefferies will act as sales agent. The Sales Agreement provides that Jefferies will be entitled to aggregate compensation for its services an amount up to 3.0% of the gross proceeds of any ordinary shares sold through Jefferies under the Sales Agreement. The Sales Agreement replaces the Company’s previous Open Market Sale AgreementSM with Jefferies, dated February 4, 2020 (the “ADS Sales Agreement”), which provided for the sale of ADSs by the Company. The Company terminated the ADS Sales Agreement upon effectiveness of the Sales Agreement following the mandatory exchange of the ADSs and the direct listing of the ordinary shares on the Nasdaq Stock Market on April 15, 2024. The ordinary shares will be offered and sold pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-267198), filed with the SEC on August 31, 2022, as amended, and declared effective by the Commission on September 12, 2022, as supplemented by the prospectus supplement dated May 8, 2024 (the “Prospectus Supplement”). The Company may offer and sell ordinary shares having an aggregate offering price of up to $100,000 under the Prospectus Supplement. Prior to termination, the Company issued and sold 640 ordinary shares pursuant to the ADS Sales Agreement during the three months ended March 31, 2024, resulting in net proceeds to the Company of approximately $9,250. The Company did not issue or sell ordinary shares during the three months ended June 30, 2024 under the Sales Agreement. Preferred Shares In March 2024, 5,194 Series A Non-Voting Convertible Preferred Shares and Series B Non-Voting Convertible Preferred Shares (“Series B Preferred Shares”) were converted to 5,194 ordinary shares at the option of the holders. Accordingly, there were no preferred shares issued and outstanding at June 30, 2024. Basis of Presentation. The unaudited condensed consolidated balance sheet as of June 30, 2024 and the interim unaudited condensed consolidated financial statements presented herein, have been prepared in accordance with U.S. GAAP, the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by U.S. GAAP for complete financial statements or all the disclosures normally made in an Annual Report on Form 10-K. Accordingly, the unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Annual Report on Form 10-K. Certain prior year amounts have been reclassified within the notes to the unaudited condensed consolidated financial statements to condense line items of the same nature to conform with the current year presentation. The unaudited condensed consolidated financial statements include the accounts of the Company and subsidiaries and reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the dates and periods presented. All intercompany accounts and transactions have been eliminated. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. Newly Issued Climate-Related Disclosure Rule. In March 2024, the SEC issued a final rule requiring public companies to disclose climate-related information in their registration statements and annual reports. For large accelerated filers, the initial disclosure rules are effective for annual periods for the year ending December 31, 2025. In April 2024, the SEC voluntarily stayed the final rule pending the completion of judicial review by the Court of Appeals for the Eighth Circuit. The Company is monitoring the development of litigation related to the SEC’s rule, and is currently evaluating the effects of the final rule on its disclosures, processes and procedures.

Fair Value Disclosures [Abstract]

Fair Value Measurement

•Income approach, which is based on the present value of a future stream of net cash flows.

•Market approach, which is based on market prices and other information from market transactions involving identical or comparable assets or liabilities.

As a basis for considering the assumptions used in these techniques, the standard establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

•Level 1 - Quoted prices for identical assets or liabilities in active markets.

•Level 3 - Unobservable inputs that reflect estimates and assumptions.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax benefit was $509 for the three months ended June 30, 2024 resulting in an effective tax rate of 3.6%. The income tax provision was $90 for the three months ended June 30, 2023 resulting in an effective tax rate of (0.1)%. The change in the effective income tax rate for the three months ended June 30, 2024, as compared to the prior period in 2023, is primarily driven by the release of uncertain tax positions due to the expiration of their statute of limitations in the current period. The income tax benefit was $416 for the six months ended June 30, 2024 resulting in an effective tax rate of 1.0%. The income tax benefit was $490 for the six months ended June 30, 2023 resulting in an effective tax rate of 0.5%. The change in the effective income tax rate for the six months ended June 30, 2024, as compared to the prior period in 2023, is primarily driven by the release of uncertain tax positions due to the expiration of their statute of limitations in the current period compared to a state tax refund received during the first quarter of the prior period. The Company's cumulative loss position was significant negative evidence in assessing the need for a valuation allowance on its deferred tax assets. Given the weight of objectively verifiable historical losses from operations, the Company has a full valuation allowance on its deferred tax assets. The Company will be able to reverse the valuation allowance when it has shown its ability to generate taxable income on a consistent basis in future periods. The valuation allowance does not have an impact on the Company's ability to utilize any net operating losses or other tax attributes to offset cash taxes payable as these items are still eligible to be used.

Commitments and Contingencies	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company is subject to potential liabilities generally incidental to its business arising out of present and future lawsuits and claims related to product liability, personal injury, contract, commercial, intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. The Company accrues for potential liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such costs can be reasonably estimated. At June 30, 2024 and December 31, 2023, there were no contingent liabilities with respect to any litigation, arbitration or administrative or other proceeding that are reasonably likely to have a material adverse effect on the Company’s consolidated financial position, results of operations, cash flows or liquidity. First Jazz Complaint On May 12, 2021, Jazz Pharmaceuticals, Inc. (“Jazz”) filed a formal complaint (the “First Complaint”) initiating a lawsuit in the United States District Court for the District of Delaware (the “Court”) against Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Management Corporation, Avadel Legacy Pharmaceuticals, LLC, Avadel Specialty Pharmaceuticals, LLC, and Avadel CNS Pharmaceuticals, LLC (collectively, the “Avadel Parties”). In the First Complaint, Jazz alleges the sodium oxybate product (“Proposed Product”) described in the NDA owned by Avadel CNS Pharmaceuticals, LLC (“Avadel CNS”) will infringe at least one claim of U.S. Patent No. 8731963, 10758488, 10813885, 10959956 and/or 10966931 (collectively, the “patents-in-suit”). The First Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. On June 3, 2021, the Avadel Parties timely filed their Answer and Counterclaims (the “Avadel Answer”) with the Court in response to the First Complaint. The Avadel Answer generally denies the allegations set forth in the First Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patents-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of each patent-in-suit, and ii) a declaratory judgment of invalidity of each patent-in-suit. On June 18, 2021, Jazz filed its Answer (“Jazz Answer”) with the Court in response to the Avadel Answer. The Jazz Answer generally denies the allegations set forth in the Avadel Answer and sets forth a single affirmative defense asserting that Avadel has failed to state a claim for which relief can be granted. On June 21, 2021, the Court issued an oral order requiring the parties to i) confer regarding proposed dates to be included in the Court’s scheduling order for the case, and ii) submit a proposed order, including a proposal for the length and timing of trial, to the Court by no later than July 21, 2021. On July 30, 2021, the Court issued a scheduling order establishing timing for litigation events including i) a claim construction hearing date of August 2, 2022, and ii) a trial date of October 30, 2023. On October 18, 2021, consistent with the scheduling order, Jazz filed a status update with the Court indicating that Jazz did not intend to file a preliminary injunction with the Court at this time. Jazz further indicated that it would provide the Court with an update regarding whether preliminary injunction proceedings may be necessary after receiving further information regarding the FDA’s action on Avadel CNS’s NDA. On January 4, 2022, the Court entered an agreed order dismissing this case with respect to Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Specialty Pharmaceuticals, LLC, Avadel Legacy Pharmaceuticals, LLC, and Avadel Management Corporation. A corresponding order was entered in the two below cases on the same day. On February 25, 2022, Jazz filed an amended Answer to the Avadel Parties’ Counterclaims (“the Jazz First Amended Answer”). The Jazz First Amended Answer is substantially similar to the Jazz Answer except insofar as it adds an affirmative defense for judicial estoppel and unclean hands. Corresponding amended answers were filed in the two below cases on the same day. On June 23, 2022, Avadel CNS filed a Renewed Motion for Judgment on the Pleadings, with respect to its counterclaim against Jazz seeking to have U.S. Patent No. 8731963 (the “REMS Patent”) delisted from the Orange Book and seeking to have the motion resolved concurrent with the parties’ Markman hearing on August 31, 2022. On July 7, 2022, Jazz filed a response styled as Objections to Avadel CNS’ Motion for Judgment on the Pleadings. On July 14, 2022, Avadel CNS replied to Jazz’s response, and on July 21, 2022, Avadel CNS requested oral argument on its delisting motion simultaneous with the Markman hearing. On August 24, 2022, the Court ordered Jazz to respond substantively to Avadel CNS’ motion, which Jazz did on August 26, 2022. Avadel CNS filed its reply on August 28, 2022. On August 23, 2022, the Markman hearing was postponed. On September 7, 2022, the case was reassigned to a new judge, and the Markman hearing was held on October 25, 2022. At the Markman hearing, Avadel CNS reiterated its request for an expedited hearing on the Renewed Motion for Judgment on the Pleadings for the delisting of the REMS Patent. On October 28, 2022, the Court granted Avadel CNS’ request and scheduled the hearing for November 15, 2022. The Court held the Markman hearing on November 15, 2022 and issued a claim construction ruling on November 18, 2022. Also, on November 18, 2022 the Court granted Avadel’s Renewed Motion for Judgment on the Pleadings and ordered Jazz to request delisting of the REMS Patent from the Orange Book. On November 22, 2022, Jazz appealed that decision and on December 14, 2022, the Federal Circuit issued a stay of the delisting order until further notice. Oral argument was held February 14, 2023. On February 24, 2023, the United States Court of Appeals for the Federal Court affirmed the previous ruling from the Court, ordering the delisting of the REMS Patent from the Orange Book, which has since occurred. On March 7, 2023, in response to a joint stipulation filed by the parties, the Court issued an order dismissing Jazz’s infringement claims against the Avadel Parties relating to the REMS Patent as well as Avadel Parties’ noninfringement and invalidity counterclaims relating to the REMS Patent. On March 15, 2023, the parties submitted a Stipulation and Proposed Order Modifying the Case Schedule to accommodate additional claim construction proceedings. That stipulation remains pending before the Court. On April 26, 2023, the parties filed their Supplemental Joint Claim Construction Brief. On July 3, 2023, the Court issued a modified scheduling order establishing a new trial date of February 26, 2024. On July 21, 2023, in response to a Court order, the parties submitted a Stipulation and Proposed Order Modifying the Case Schedule with an updated proposed schedule to accommodate additional claim construction proceedings. On August 4, 2023, the Court entered a modified version of the parties’ proposed schedule, which was revised on August 28, 2023. The parties’ Second Supplemental Joint Claim Construction Brief was filed on October 10, 2023, and a Markman hearing regarding the disputed terms occurred on November 1, 2023. The Court issued its claim construction order on December 15, 2023. On August 15, 2023, Avadel renewed its request to consolidate this litigation with the litigation described in the Avadel Complaint below. On November 3, 2023, the Court denied that request. On November 30, 2023, the parties filed cross motions for summary judgment. The parties filed opposition briefs on December 15, 2023. The parties filed reply briefs on December 22, 2023. On February 14, 2024, the Court denied the parties’ summary judgment motions. On February 15, 2024, the Court held its Pretrial Conference. Trial was held from February 26, 2024 to March 1, 2024 (the “February Patent Trial”). On March 4, 2024, the jury returned a verdict of no infringement for U.S. Patent No. 10758488 and infringement of U.S. Patent No. 11147782, with damages of $234, which are included in the unaudited condensed consolidated balance sheets in other non-current liabilities at June 30, 2024. On March 19, 2024, the Court issued a Supplemental Scheduling Order setting a June 4, 2024 hearing on Jazz’s request for a permanent injunction or ongoing royalty. An ongoing royalty, if any, will be determined by the Court, and a range of possible loss, if any, cannot be reasonably estimated at this time. Briefing on Jazz’s request closed on May 20, 2024, and the hearing was held June 4, 2024. Jazz’s request remains pending. Second Jazz Complaint On August 4, 2021, Jazz filed another formal complaint (the “Second Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Second Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of U.S. Patent No. 11077079. The Second Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. On September 9, 2021, the Avadel Parties timely filed their Answer and Counterclaims (the “Second Avadel Answer”) with the Court in response to the Second Complaint. The Second Avadel Answer generally denies the allegations set forth in the Second Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity of the patent-in-suit. On October 22, 2021, the Court issued an oral order stating that this case should proceed on the same schedule as the case filed on May 12, 2021. On September 7, 2022, the case was reassigned to a new judge. Third Jazz Complaint On November 10, 2021, Jazz filed another formal complaint (the “Third Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Third Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of U.S. Patent No. 11147782. The Third Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. This case will proceed on the same schedule as the cases associated with the First and Second Complaints above. On December 21, 2021, the Court entered a revised schedule for the First, Second and Third Complaints, setting a new claim construction date of August 31, 2022. On January 7, 2022, Avadel CNS timely filed its Answer and Counterclaims (the “Third Avadel Answer”) with the Court in response to the Third Complaint. The Third Avadel Answer generally denies the allegations set forth in the Third Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity/unenforceability of the patent-in-suit. On September 7, 2022, the case was reassigned to a new judge. Fourth Jazz Complaint On July 15, 2022, Jazz filed another formal complaint (the “Fourth Complaint”) initiating a lawsuit in the Court against Avadel CNS. In the Fourth Complaint, Jazz alleges the Proposed Product described in the NDA owned by Avadel CNS will infringe at least one claim of the REMS Patent, which was asserted in the First Complaint. The FDA required Avadel CNS to file a Paragraph IV certification against the REMS Patent, which Avadel CNS did under protest, consistent with its Renewed Motion for Judgment on the Pleadings for the delisting of the REMS Patent from the Orange Book, which was later ordered to be delisted in the above First Jazz Complaint action. Avadel CNS provided the required notice of its Paragraph IV certification to Jazz, and Jazz reasserted the REMS Patent in a separate action following receipt of that notice. The Fourth Complaint further includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. On September 7, 2022, the case was reassigned to a new judge. On September 21, 2022, Jazz served the Fourth Complaint. On October 21, 2022, Avadel CNS timely filed its Answer and Counterclaims (the “Fourth Avadel Answer”) with the Court in response to the Fourth Complaint. The Fourth Avadel Answer generally denies the allegations set forth in the Fourth Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit), and asserts a number of counterclaims for i) a declaratory judgment of non-infringement of the patent-in-suit, ii) a declaratory judgment of invalidity/unenforceability of the patent-in-suit, iii) delisting of the patent-in-suit from the Orange Book; iv) monopolization under the Sherman Antitrust Act of 1890 (the “Sherman Act”); and v) attempted monopolization under the Sherman Act. On December 9, 2022, Jazz filed a Motion to Dismiss Avadel’s Antitrust Counterclaims. Avadel filed its opposition brief on December 27, 2022, and Jazz filed its reply brief on January 6, 2022. On January 11, 2023, Avadel filed a request for oral argument on the motion. On May 24, 2024, the Court denied Jazz’s Motions to Dismiss. On June 7, 2024, Jazz filed its Answer to Avadel’s Counterclaims. On March 6, 2023, the parties filed a stipulation of dismissal, dismissing Jazz’s claims with respect to the REMS Patent and Avadel CNS’s related non-infringement and invalidity counterclaims. The Court entered that stipulation on March 7, 2023. On May 19, 2023, the Court issued a scheduling order establishing timing for litigation events including i) completion of fact discovery by March 14, 2024, and ii) a deadline for case dispositive motions of September 20, 2024. On January 23, 2024, the parties submitted a stipulation to extend the case schedule. On January 24, 2024, the Court ordered an extension of the case schedule, including i) completion of fact discovery by June 20, 2024 and ii) a deadline for case dispositive motions by January 31, 2025. On January 24, 2024, the Court issued an order setting a pretrial conference for October 30, 2025 and a 5-day trial to begin on November 3, 2025. On April 22, 2024, the parties submitted a stipulation extending certain pretrial deadlines, including i) extending completion of fact discovery to September 27, 2024 and ii) extending the deadline for case dispositive motions to April 4, 2025. On June 29, 2023, Jazz filed a Motion to Stay the case, pending resolution of its Motion to Dismiss. Briefing on that Motion to Stay closed on August 10, 2023. On March 13, 2024, Jazz filed a Supplemental Motion to Stay, pending the resolution of the post-trial briefing and any appeals from the February Patent Trial. On May 24, 2024, the Court denied Jazz’s Motions to Stay. On June 7, 2024, Jazz filed a Motion for Reargument or in the Alternative to Certify an Appeal. Avadel filed its opposition brief on June 28, 2024. Jazz filed its reply brief on July 12, 2024. Jazz’s motion remains pending. Avadel Complaint On April 14, 2022, Avadel CNS and Avadel Pharmaceuticals plc (collectively the “Avadel Plaintiffs”) filed a formal complaint (the “Avadel Complaint”) initiating a lawsuit in the Court against Jazz and Jazz Pharmaceuticals Ireland Ltd. (collectively, the “Jazz Parties”). In the Avadel Complaint, the Avadel Plaintiffs allege that the Jazz Parties breached certain confidential disclosure agreements and misappropriated certain of the Avadel Plaintiffs’ trade secrets. The Avadel Complaint further includes typical relief requests such as injunctive relief, monetary damages and attorneys’ fees, costs and expenses, as well as seeking correction of inventorship of certain Jazz patents, for which the Jazz Parties claim ownership, to include former Avadel Plaintiffs’ scientists. On June 2, 2022, Jazz answered the Avadel Complaint. The Answer generally denies the allegations set forth in the Avadel Complaint and includes various affirmative defenses. On July 8, 2022, Jazz filed a Motion for Judgment on the Pleadings seeking to have all Counts dismissed for failure to state a claim upon which relief can be granted. The Avadel Plaintiffs’ response to that Motion was filed with the Court on July 29, 2022. Jazz’s reply was filed with the Court on August 5, 2022. On February 2, 2023, the Court held a hearing on Jazz’s Motion for Judgment on the Pleadings. On September 7, 2022, the case was reassigned to a new judge. On February 2, 2023, the Court held a hearing on Jazz’s Motion for Judgment on the Pleadings. On July 18, 2023, the Court denied Jazz’s Motion for Judgment on the Pleadings. On August 15, 2023, the parties submitted competing proposed scheduling orders, and Avadel requested consolidation with the above First Jazz Complaint litigation. That request for consolidation was denied on November 3, 2023. On November 17, 2023, the parties submitted an updated joint proposed scheduling order. On January 30, 2024, the parties agreed to a 6-week stay of discovery and submitted a proposed stipulation extending certain case deadlines to accommodate the same. On February 9, 2024, the parties submitted an updated proposed scheduling order consistent with that stipulation, setting the close of fact discovery for August 9, 2024 and a trial date of December 15, 2025. That proposed scheduling order remains pending before the Court as of the date of this Quarterly Report on Form 10-Q. On March 19, 2024, Jazz filed a Motion to Stay, pending the resolution of the post-trial briefing and any appeals from the February Patent Trial. On May 24, 2024, the Court denied Jazz’s Motions to Stay.

This suit alleges that the FDA’s approval of LUMRYZ was an unlawful agency action and asks the DC Court to set aside FDA’s approval of LUMRYZ. On June 28, 2023, the DC Court granted Avadel CNS’s unopposed motion to intervene in the case to defend the FDA’s decision. On August 14, 2023, the Court entered a scheduling order establishing timing for litigation events including early summary judgment briefing closing December 22, 2023. On September 22, 2023, Jazz filed its Motion for Summary Judgment. On October 20, 2023, the FDA and Avadel filed their Cross Motions for Summary Judgment. Briefing on the parties’ motions closed January 4, 2024. On February 14, 2024, the Court set hearing for oral argument on the parties’ motions for February 27, 2024.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. The Company is registered as an Irish public limited company. The Company’s headquarters are in Dublin, Ireland with operations in Dublin, Ireland and St. Louis, Missouri, United States (“U.S.”). LUMRYZ is an extended-release formulation of sodium oxybate indicated to be taken once at bedtime for the treatment of cataplexy or excessive daytime sleepiness (“EDS”) in adults with narcolepsy. LUMRYZ was approved by the U.S. Food and Drug Administration (“FDA”) on May 1, 2023. The FDA also granted Orphan Drug Exclusivity (“ODE”) to LUMRYZ for a period of seven years until May 1, 2030. In June 2023, the Company commercially launched LUMRYZ in the U.S. In approving LUMRYZ, the FDA approved a risk evaluation and mitigation strategy (“REMS”) for LUMRYZ to help ensure that the benefits of the drug in the treatment of cataplexy and EDS in narcolepsy outweigh the risks of serious adverse outcomes resulting from inappropriate prescribing, misuse, abuse, and diversion of the drug. Under this REMS, healthcare providers who prescribe the drug must be specially certified; pharmacies that dispense the drug must be specially certified; and the drug must be dispensed only to patients who have enrolled in the LUMRYZ REMS and completed all REMS requirements, including documentation of safe use conditions. As of the date of this Quarterly Report, the Company’s only commercialized product is LUMRYZ. The Company continues to evaluate opportunities to expand its product portfolio.
Liquidity	Liquidity. The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

Newly Issued Climate-Related Disclosure Rule	Newly Issued Climate-Related Disclosure Rule. In March 2024, the SEC issued a final rule requiring public companies to disclose climate-related information in their registration statements and annual reports. For large accelerated filers, the initial disclosure rules are effective for annual periods for the year ending December 31, 2025. In April 2024, the SEC voluntarily stayed the final rule pending the completion of judicial review by the Court of Appeals for the Eighth Circuit. The Company is monitoring the development of litigation related to the SEC’s rule, and is currently evaluating the effects of the final rule on its disclosures, processes and procedures.
