Insights

Mallinckrodt's Q4 and FY2024 results demonstrate a company successfully executing its strategic priorities while managing a complex product portfolio. The 6.1% annual revenue growth to $2.0 billion represents solid performance, particularly in key product segments. The standout performers were Acthar Gel with 14.2% growth and the Specialty Generics division with an impressive 15.4% growth.

What's particularly notable is Mallinckrodt's significant deleveraging, reducing total debt by 47% and net debt by approximately 64%. This substantially strengthens the balance sheet and provides greater financial flexibility going forward. With a year-end cash position of $382.6 million against $865.6 million in debt, the company has dramatically improved its debt-to-cash ratio.

However, there are some concerning signals in the 2025 guidance. The projected revenue range of $1.7-1.8 billion represents a potential 10-15% decline from 2024's $2.0 billion. Similarly, the $480-520 million Adjusted EBITDA guidance suggests potential contraction from the $603.7 million achieved in 2024. This guidance requires careful scrutiny, as it may reflect anticipated competitive pressures, particularly for INOmax which saw a 13.8% sales decline due to competition.

The 41.8% decrease in Q4 net income to $612.8 million warrants attention, though the stable Adjusted EBITDA suggests this may be due to non-operational factors. The successful SelfJect device launch for Acthar Gel demonstrates effective product lifecycle management, which is essential for maintaining growth in mature pharmaceutical products.

Mallinckrodt's 2024 performance reveals important dynamics within their specialized pharmaceutical portfolio. The resurgence of Acthar Gel is particularly significant - achieving four consecutive quarters of growth and a 33% increase in Q4 sales signals successful rejuvenation of this mature product. The SelfJect device introduction represents effective lifecycle management, driving new prescription growth by improving the administration experience for patients using this complex biologic.

The contrasting trajectories of key products highlight the competitive challenges in specialty pharmaceuticals. While Acthar Gel and Terlivaz are gaining momentum, INOmax faces significant headwinds with a 14% sales decline due to competitive pressure in the nitric oxide market. The company's strategy to stabilize INOmax through the EVOLVE DS delivery system deployment shows awareness of the need for differentiation beyond the molecule itself in maintaining market position.

The exceptional performance in Specialty Generics (15.4% growth) deserves particular attention. In an industry plagued by quality issues and supply disruptions, Mallinckrodt has successfully positioned itself as a reliable supplier of controlled substances and finished dosage products. This reliability premium has translated into substantial growth, though the anticipated moderation to flat or low-single digit growth in 2025 suggests the company expects competitors to resolve their manufacturing challenges.

The mention of a "proposed transaction with Endo" in the final paragraph is noteworthy, as consolidation in specialty pharmaceuticals could significantly reshape Mallinckrodt's competitive position and strategic direction. The substantial debt reduction achieved in 2024 likely improves their strategic flexibility in pursuing such corporate development opportunities.

Achieved High End of Full-Year Net Sales Guidance Range and Midpoint of Adjusted EBITDA Guidance Range

Grew Full-Year Net Sales by 6.1% to $2.0 Billion, with 14.2% Growth in Acthar^® Gel (repository corticotropin injection) and 15.4% Growth in Specialty Generics; Reduced Total Debt by 47% and Net Debt by Approximately 64%

Acthar Gel Returned to Growth with Successful Launch of SelfJect™ Device; Uptake of INOmax^®EVOLVE™ DS Delivery System Accelerated in Second Half of the Year

Expects 2025 Net Sales of $1.7 Billion to $1.8 Billion and Adjusted EBITDA of $480 Million to $520 Million

DUBLIN, March 13, 2025 /PRNewswire/ -- Mallinckrodt plc ("Mallinckrodt" or the "Company"), a global specialty pharmaceutical company, today reported its financial results for the fourth quarter and fiscal year ended December 27, 2024.¹

"Our strong performance in 2024 reflects the disciplined execution of our strategy to position Mallinckrodt for long-term success," said Siggi Olafsson, President and Chief Executive Officer. "In Specialty Brands, Acthar Gel returned to growth, marking a key milestone for the brand, with four consecutive quarters of rising net sales. This was driven by prescriber enthusiasm, patient demand and the launch of SelfJect for Acthar Gel, which has exceeded our expectations. We are continuing the commercial rollout of our INOmax EVOLVE DS delivery system to U.S. hospitals nationwide and are pleased with the positive feedback to date. Additionally, we meaningfully grew Terlivaz^® (terlipressin) for injection in 2024 and continue to engage with providers about the benefits of early patient identification and treatment."

Mr. Olafsson added, "In Specialty Generics, we closed out an exceptional year, with double-digit net sales growth driven by rising demand and our ability to consistently and reliably deliver high-quality products. As we move through 2025 and beyond, we will continue to advance our strategic priorities as we build toward long-term sustainable growth and value creation for all our stakeholders."

Fourth Quarter 2024 Financial Results

Mallinckrodt's net sales in the fourth quarter of 2024 were $492.1 million, as compared to $469.3 million in the fourth quarter of 2023. This reflects 4.9% growth on a reported basis and 4.8% growth on a constant currency basis.

The Company's Specialty Brands segment reported net sales of $265.6 million, as compared to $270.7 million in the fourth quarter of 2023. This 1.9% decrease includes the impact of the Therakos^® sale. Excluding Therakos, Specialty Brands net sales grew by 8.9%, driven by growth in Acthar Gel and uptake in SelfJect and Terlivaz.

Mallinckrodt's Specialty Generics segment reported net sales of $226.5 million, as compared to $198.6 million in the fourth quarter of 2023. This 14.0% growth was driven by the Company's established track record as a reliable and consistent producer of high-quality products amidst market shortages due to quality and other disruptions, in both the finished dosage products and Controlled Substances active pharmaceutical ingredient (API) businesses, partially offset by a decline in the Acetaminophen (APAP) business as a result of overall softening of the market.

The Company's net income for the fourth quarter was $612.8 million, a 41.8% decrease as compared to net income of $1.05 billion in the fourth quarter of 2023.

Mallinckrodt's Adjusted EBITDA in the fourth quarter was $124.2 million, essentially flat compared to $123.8 million in the fourth quarter of 2023. This stability was driven by strength in both the Specialty Generics segment and Acthar Gel, largely offset by approximately $9.0 million of transaction-related compensation expenses related to the sale of Therakos, the impact of the Therakos transaction, incremental commercial investments for Acthar Gel and Terlivaz, and the impact of nitric oxide competition in the U.S.

Gross profit as a percentage of net sales was 50.2% for the fourth quarter, as compared to 17.2% for the fourth quarter of 2023. Adjusted gross profit as a percentage of net sales was 63.0% for the fourth quarter, as compared to 62.3% for the fourth quarter of 2023.

Mallinckrodt's cash balance at the end of the fourth quarter of 2024 was $382.6 million. Total outstanding principal debt was $865.6 million, a reduction of 47% compared to the end of 2023, and outstanding net debt was $492.1 million, a reduction of approximately 64% compared to the end of 2023.

Fiscal Year 2024 Results¹

Mallinckrodt's net sales were $1.98 billion, an increase of 6.1% compared to $1.87 billion in fiscal 2023.

Full-year net sales in the Specialty Brands segment were $1.08 billion in fiscal 2024, essentially flat compared to $1.09 billion in fiscal 2023. Excluding Therakos, Specialty Brands net sales grew 1.4%. Full-year net sales in the Specialty Generics segment were $896.3 million, an increase of 15.4% compared to $776.9 million in fiscal 2023 reflecting the factors discussed above.

The Company recorded net income of $477.9 million in fiscal 2024, a substantial improvement as compared to a net loss of $1.67 billion in fiscal 2023.

Mallinckrodt's Adjusted EBITDA was $603.7 million in fiscal 2024, an increase of 5.6% compared to $571.9 million in fiscal 2023. Excluding the impact of the Therakos business, Adjusted EBITDA grew by 12.9%.

Business Segment Updates & Outlook

Specialty Brands

Acthar Gel net sales were $138.8 million in the fourth quarter, an increase of 33.0% versus the prior year period, and $485.7 million for the full year, an increase of 14.2%. Growth in the fourth quarter was driven by the successful launch of SelfJect, which accounted for more than 70% of new Acthar Gel prescriptions, as well as prescriber enthusiasm and patient demand. The Company expects Acthar Gel to continue its momentum and grow in the low-single digits in 2025.

Terlivaz net sales were $6.1 million in the fourth quarter, up from $5.6 million in the same period last year, and $24.7 million for the full year, up from $15.6 million. The Company continues to engage with healthcare providers to highlight the benefits of early patient identification and treatment initiation.

INOmax (nitric oxide) net sales were $60.8 million in the fourth quarter, down 14.0% compared to the prior year period, and full-year net sales were $261.4 million, down 13.8%, primarily due to competitive pressures in the U.S. The Company remains focused on the multi-year rollout of the INOmax EVOLVE DS delivery system and continues to believe this new offering will help stabilize the brand.

Specialty Generics

Mallinckrodt expects the Specialty Generics segment to deliver flat to low-single digit sales growth in full-year 2025, driven by the Company's strong market position and performance in finished-dosage products, demand for Controlled Substance APIs and the Company's differentiated position as a consistent supplier of high-quality products, moderated by softness in the APAP market, which is expected to continue.

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 fourth quarter.

Please see the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections of the Company's Annual Report on Form 10-K for the year ended December 27, 2024 filed with the U.S. Securities and Exchange Commission (SEC) for additional information.

2025 Financial Guidance

For the full-year fiscal 2025, Mallinckrodt expects:

	2025 Guidance
Total Net Sales	$1.7 billion to $1.8 billion
Adjusted EBITDA	$480 million to $520 million

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.

Update on Fourth Quarter and Fiscal Year 2024 Conference Call and Webcast

Mallinckrodt will no longer host its previously planned quarterly conference call and webcast this morning. Mallinckrodt has issued a separate press release this morning in conjunction with a proposed transaction with Endo, Inc. which includes the details of a joint conference call and webcast to be held this morning. The Company has posted prepared remarks regarding its fourth quarter and fiscal year 2024 financial results on the Investor Relations section of its website at https://ir.mallinckrodt.com/.

Mallinckrodt 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.

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, net sales growth (loss) on a constant-currency basis, and net debt, which are considered "non-GAAP" financial measures under applicable SEC rules and regulations.

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 taxes; depreciation; amortization from intangible assets and right-of use asset resulting from finance leases; restructuring charges, net; non-restructuring impairment charges; inventory step-up expense; discontinued operations; changes in fair value of contingent consideration obligations; significant legal and environmental charges; divestitures; liabilities management and separation costs; losses on debt extinguishment, net; unrealized gain or loss on equity investment; reorganization items, net; share-based compensation; fresh-start inventory related expenses; and other items identified by the Company.

Full-year 2024 adjusted EBITDA for Therakos is calculated consistently with the Company Adjusted EBITDA and also includes operating expenses allocated to the Therakos business.

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.

Segment net sales growth (loss) on a constant-currency basis measures the change in segment net sales between current- and prior-year periods using a constant currency, the exchange rate in effect during the applicable prior-year period.

Net debt of $492.1 million as of December 27, 2024, reflects $865.6 million in total debt principal outstanding and $9.1 million in undiscounted finance lease liabilities on a GAAP basis less $382.6 million in cash and cash equivalents (unrestricted cash) on a GAAP basis.

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 Mallinckrodt'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.

Predecessor and Successor Periods

Mallinckrodt's financial results presented in this press release include Successor and Predecessor periods.

The year ended December 27, 2024 and the period from November 15, 2023 through December 29, 2023 reflect the Successor periods, while the period December 31, 2022 through, and including, November 14, 2023 reflects the Predecessor period. We do not believe that reviewing the results of the Successor period in isolation would be useful in identifying trends in or reaching conclusions regarding our overall operating performance. Management believes that our key performance metrics such as net sales and segment operating income (loss) for the year ended December 27, 2024 (Successor) provide a meaningful comparison and are useful in identifying current business trends when compared to the year ended December 29, 2023 (Successor).

The Company reports its results based on a "52-53 week" year ending on the last Friday of December. The year ended December 27, 2024 (Successor) ("fiscal 2024") and the combined periods of December 31, 2022 through November 14, 2023 (Predecessor) and November 15, 2023 through December 29, 2023 (Successor) ("fiscal 2023") consisted of 52 weeks. The three months ended December 27, 2024 and the combined periods of September 30, 2023 through November 14, 2023 and November 15, 2023 through December 29, 2023 ("three months ended December 29, 2023") consisted of 13 weeks.

Mallinckrodt's results of operations as reported in its unaudited consolidated financial statements for the Successor and Predecessor periods are in accordance with GAAP. The comparison of the Predecessor and Successor periods for the periods presented here is not in accordance with GAAP. However, the Company believes that the comparison is useful for management and investors to assess Mallinckrodt's ongoing financial and operational performance and trends.
