**Mallinckrodt Reports Third Quarter 2025 Financial Results**

*Delivers Third Quarter Net Sales of $753.1 Million, Driven by Acthar*<sup>®</sup> *Gel (repository corticotropin injection) Growth and the Inclusion of Two Months of Endo Product Net Sales*

*Expects Fourth Quarter 2025 Net Sales of $485 Million to $505 Million and Adjusted EBITDA <br>of $155 Million to $165 Million for Keenova*

*Raises Full-Year Acthar Gel Net Sales Growth Guidance to 30% to 35%, Reflecting Strong Brand Momentum*

*Conference Call and Webcast Today at 8:00 a.m. ET*

**DUBLIN, November 10, 2025** – <u>Mallinckrodt plc</u> ("Mallinckrodt" or the "Company") today reported its financial results for the third quarter of 2025, which include combined business results following the completion of Mallinckrodt's merger with Endo, Inc. ("Endo") on July 31, 2025. As announced today in a separate press release, Mallinckrodt has completed the spin-off of its combined generics and sterile injectables businesses under the name Par Health, Inc. ("Par Health") and is introducing the combined branded therapeutics business, Keenova Therapeutics ("Keenova").

"We are excited to begin our next chapter as Keenova Therapeutics, a pure-play branded therapeutics company focused on addressing unmet patient needs," said Siggi Olafsson, President and Chief Executive Officer. "The third-quarter results of our branded therapeutics portfolio reflect the promise that our future holds. Our team delivered another quarter of robust double-digit growth in Acthar Gel, driven by growing demand and a broadening prescriber base. We were also pleased to advance our XIAFLEX<sup>®</sup> (collagenase clostridium histolyticum) pipeline with the initiation of a new clinical program focused on hammertoe for which we have already recruited over 30 patients. We are on track to have a strong finish to the year, as reflected in the fourth quarter guidance we are providing for Keenova."

Mr. Olafsson added, "Following the merger with Endo and the Par Health spin-off, we are moving forward with enhanced resources, focus and scale to bring important therapies to our patients. The energy our teams have for Keenova's future is inspiring, and I am grateful for their deep dedication as we strive to deliver greater benefits for our patients and enhanced value for partners and shareholders."

**Segment Updates**

The Company's consolidated and segment operating results for the three months ended September 26, 2025 reflect the inclusion of two months of Endo's performance. The Company operated its business in three reportable segments, as a result of the merger:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The **Specialty Brands** segment, which represents a combination of Mallinckrodt's historical "Specialty Brands" reportable segment and Endo's historical "Branded Pharmaceuticals" reportable segment, is focused on autoimmune and rare diseases across a range of therapeutic areas and includes Acthar Gel, XIAFLEX, and other branded therapeutics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The **Generics** segment represents a combination of Mallinckrodt's historical "Specialty Generics" reportable segment and Endo's historical "Generic Pharmaceuticals" reportable segment and includes a product portfolio consisting of certain controlled substances, patches, solid oral extended-release products, solid oral immediate-release products, liquids, semi-solids, powders and opthalmics that treat and manage a wide variety of medical conditions, as well as active pharmaceutical ingredients ("API").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The **Sterile Injectables** segment, which represents Endo's historical "Sterile Injectables" reportable segment, consists primarily of branded and generic sterile injectable products.

Going forward, Keenova comprises the Specialty Brands segment, and Par Health comprises the Generics and Sterile Injectables segments.

------

**Third-Quarter 2025 Financial Results**

The Company's total **net sales** in the third quarter of 2025 were $753.1 million, compared to $505.5 million in the third quarter of 2024, an increase of 49.0%. This includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Specialty Brands net sales of $416.0 million, compared to $286.0 million in the third quarter of 2024, a 45.5% increase. Growth was primarily driven by an increase in Acthar Gel net sales of $55.0 million, or 43.5%, compared to the third quarter of 2024, to $181.4 million, and the inclusion of XIAFLEX net sales of $90.1 million as a result of the merger with Endo, partially offset by the divestiture of Therakos<sup>®</sup>; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Generics and Sterile Injectables net sales of $337.1 million, compared to $219.5 million in the third quarter of 2024, an increase of 53.6%.

The Company's **net loss** for the third quarter of 2025 was $291.1 million compared to a net loss of $26.2 million in the third quarter of 2024, primarily due to $123.3 million of compensation expenses related to the merger of Mallinckrodt and Endo, approximately $93.8 million of cash costs related to the merger of Mallinckrodt and Endo and separation of Par Health, and approximately $148.8 million of non-cash expenses related to the fair value adjustments of inventory and intangible assets, partially offset by strength in Acthar Gel.

The Company's **adjusted EBITDA** in the third quarter of 2025 was $111.3 million, compared to $160.6 million in the third quarter of 2024, with the decrease primarily due to the aforementioned $123.3 million of compensation expenses related to the merger of Mallinckrodt and Endo, partially offset by strength in Acthar Gel and two months of adjusted EBITDA contribution from XIAFLEX and Endo's other products.

**Financial Guidance and Update on Transaction Synergies**

Keenova is raising 2025 full-year net sales growth guidance for Acthar Gel from a range of 20% to 30% to a range of 30% to 35%.

Keenova is also providing guidance for the fourth quarter of 2025 for net sales and adjusted EBITDA.

---

| | |
|:---|:---|
| | Fourth Quarter 2025 <sup>1</sup> |
| Net Sales | $485 million to $505 million |
| Adjusted EBITDA <sup>2</sup> | $155 million to $165 million |

---

Keenova remains on track to realize and benefit from approximately $75.0 million of pre-tax, run-rate synergies in the first 12 months post-merger and at least $150.0 million of annual pre-tax, run-rate synergies by year three post-merger, primarily driven by business function integration and savings from economies of scale, among other areas, in connection with Mallinckrodt's merger with Endo.

The Company does not provide comparable GAAP measures for its forward-looking non-GAAP guidance or a reconciliation of such measures because the reconciling items described in the definition of adjusted EBITDA provided below are inherently uncertain and difficult to estimate and cannot be predicted without unreasonable effort. The variability of such items may have a significant impact on our future GAAP results.

Please see "Non-GAAP Financial Measures" included in this release for a discussion of non-GAAP measures and reconciliation of GAAP and non-GAAP financial measures for the third quarter.

Please see the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections of the Company's Quarterly Report on Form 10-Q for the quarter ended September 26, 2025, to be filed with the U.S. Securities and Exchange Commission ("SEC") for additional information.

<sup>1</sup> Guidance for fourth quarter of 2025 provided on a go-forward basis, excluding Par Health results from September 27, 2025 to November 10, 2025.

<sup>2</sup> Represents adjusted EBITDA as calculated in accordance with Mallinckrodt GAAP-Adjusted policy (i.e., employee cash compensation not considered an add-back).

**About Keenova**

Keenova Therapeutics is a leading global developer and manufacturer of branded therapeutics that strives to help patients with rare or unaddressed conditions live happier and healthier lives.

The Company's diversified brands portfolio is focused across a wide range of therapeutic areas of significant unmet need, including endocrinology, gastroenterology, hepatology, immunology, neonatal respiratory critical care, nephrology, neurology, pulmonology, ophthalmology, orthopedics, rheumatology, and urology. Globally headquartered in Dublin, Ireland, Keenova benefits from a strong U.S. manufacturing footprint with facilities in Louisiana, New Jersey, New York, Pennsylvania and Wisconsin. To learn more, please visit <u>www.keenova.com</u>.

Keenova uses its website as a channel of distribution of important company information, such as press releases, investor presentations and other financial information. It also uses its website to expedite public access to time-critical information regarding the Company in advance of or in lieu of distributing a press release or a filing with the SEC disclosing the same information. Therefore, investors should look to the Investor Relations page of the website for important and time-critical information. Visitors to the website can also register to receive automatic e-mail and other notifications alerting them when new information is made available on the Investor Relations page of the website.

**Non-GAAP Financial Measures**

This press release contains financial measures, including adjusted EBITDA, adjusted gross profit, adjusted selling, general, and administrative ("SG&A") expenses, adjusted research and development ("R&D") expenses, and net debt, which are considered "non-GAAP" financial measures under applicable SEC rules and regulations.

The Company has provided these adjusted financial measures because they are used by management, along with financial measures in accordance with GAAP, to evaluate the Company's operating performance and liquidity. In addition, the Company believes that they will be used by investors to measure the Company's operating results. Management believes that presenting these adjusted measures provides useful information about the Company's performance across reporting periods on a consistent basis by excluding items that the Company does not believe are indicative of its core operating performance.

These adjusted measures should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. The Company's definition of these adjusted measures may differ from similarly titled measures used by others.

Because adjusted financial measures exclude the effect of items that will increase or decrease the Company's reported results of operations, management strongly encourages investors to review the Company's unaudited condensed consolidated financial statements and publicly filed reports in their entirety. A reconciliation of certain of these historical adjusted financial measures to the most directly comparable GAAP financial measures is included in the tables accompanying this release.

Further information regarding non-GAAP financial measures can be found on the Investor Relations page of the Company's website.

*Adjusted EBITDA* 

Adjusted EBITDA represents net income or loss prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP") and adjusted for certain items that management believes are not reflective of the operational performance of the business. Adjustments to GAAP amounts include, as applicable to each measure, interest expense, net; income tax expense; depreciation and amortization; combination, integration, and other related expenses; restructuring charges, net; liabilities management and separation costs; gains/losses on debt extinguishment; gains/losses on divestitures; income from discontinued operations; fresh-start inventory-related expenses; business combination inventory-related expense; share-based compensation; changes in fair value of contingent consideration obligations; changes in derivative assets and liabilities fair value; unrealized gain/loss on equity investments; reorganization items, net; recovery of bad debt - customer bankruptcy; and other items identified by the Company.

*Adjusted gross profit, adjusted SG&A expenses and adjusted R&D expenses*

Adjusted gross profit, adjusted SG&A expenses and adjusted R&D expenses represent amounts prepared in accordance with GAAP, adjusted for certain items that management believes are not reflective of the operational performance of the business. Adjustments to GAAP amounts include, as applicable to each measure, the aforementioned items in the adjusted EBITDA paragraph. The adjustments for these items are on a pre-tax basis for adjusted gross profit and adjusted SG&A expenses.

*Net debt*

Net debt of $2,657.0 million as of September 26, 2025, reflects $3,685.0 million in total debt outstanding and $19.9 million in undiscounted finance lease liabilities less $1,047.9 million in cash and cash equivalents (unrestricted cash) on a GAAP basis.
