STOUGHTON, Mass., May 12, 2026 (GLOBE NEWSWIRE) -- Collegium Pharmaceutical, Inc. (Nasdaq: COLL), today announced that it has completed the acquisition of AZSTARYS (serdexmethylphenidate and dexmethylphenidate), a central nervous system (CNS) stimulant prescription medicine used for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in people 6 years of age and older. Collegium also raised its 2026 financial guidance to include the anticipated impact of the AZSTARYS acquisition.

“We are pleased to complete the acquisition of AZSTARYS, a highly strategic addition to our portfolio that strengthens our position in ADHD and further reinforces our long-standing commitment to improving patient care and delivering shareholder value,” said Vikram Karnani, President and Chief Executive Officer. “AZSTARYS is a complementary and differentiated therapy that expands the treatment options we can offer patients and prescribers, and we look forward to rapidly integrating it into our existing commercial infrastructure. This transaction aligns with our disciplined capital deployment approach, and we expect it to be immediately accretive, enabling us to raise our 2026 financial guidance.”

Strategic Rationale

• Strategically aligns with Collegium’s mission of building a leading, diversified biopharmaceutical company committed to improving the lives of people living with serious medical conditions by expanding its position in ADHD and further diversifying its commercial portfolio beyond responsible pain management.
• Leverages Collegium’s established ADHD commercial infrastructure and expertise to accelerate AZSTARYS’ growth trajectory and drive operational efficiencies, further strengthening Collegium’s financial position. Annual run rate synergies expected to be in excess of $50 million within twelve months.
• Strengthens Collegium’s position in ADHD. AZSTARYS generated more than 760,000 prescriptions in 2025 and adds a complementary medicine to Collegium’s ADHD portfolio. AZSTARYS is expected to generate $60 to $70 million of net revenue during the remainder of 2026.
• Expected to extend the longevity of Collegium’s revenue base as AZSTARYS is supported by six Orange Book-listed patents, most of which do not expire until December 2037.
• Further strengthens Collegium’s financial position by increasing revenues, supporting margin expansion, and enhancing future cash flow generation.

Collegium may also pay Corium Therapeutics up to $135 million in additional consideration if AZSTARYS achieves certain future commercial and manufacturing milestones.

Non-GAAP Financial Measures

To supplement our financial results presented on a GAAP basis, we have included information about certain non-GAAP financial measures. We believe the presentation of these non-GAAP financial measures, when viewed with our results under GAAP and the accompanying reconciliations, provide analysts, investors, lenders, and other third parties with insights into how we evaluate normal operational activities, including our ability to generate cash from operations, on a comparable year-over-year basis and manage our budgeting and forecasting. In addition, certain non-GAAP financial measures, primarily adjusted EBITDA, are used to measure performance when determining components of annual compensation for substantially all non-sales force employees, including senior management.

In this press release we discuss the following financial measures that are not calculated in accordance with GAAP.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that represents GAAP net income or loss adjusted to exclude interest expense, interest income, the benefit from or provision for income taxes, depreciation, amortization, stock-based compensation, and other adjustments to reflect changes that occur in our business but do not represent ongoing operations. Adjusted EBITDA, as used by us, may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

There are several limitations related to the use of adjusted EBITDA rather than net income or loss, which is the nearest GAAP equivalent, such as:

• adjusted EBITDA excludes depreciation and amortization, and, although these are non-cash expenses, the assets being depreciated or amortized may have to be replaced in the future, the cash requirements for which are not reflected in adjusted EBITDA;
• adjusted EBITDA does not reflect changes in, or cash requirements for, working capital needs;
• adjusted EBITDA does not reflect the benefit from or provision for income taxes or the cash requirements to pay taxes;
• adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;
• we exclude stock-based compensation expense from adjusted EBITDA although: (i) it has been, and will continue to be for the foreseeable future, a significant recurring expense for our business and an important part of our compensation strategy; and (ii) if we did not pay out a portion of our compensation in the form of stock-based compensation, the cash salary expense included in operating expenses would be higher, which would affect our cash position;
• we exclude impairment expenses from adjusted EBITDA and, although these are non-cash expenses, the asset(s) being impaired may have to be replaced in the future, the cash requirements for which are not reflected in adjusted EBITDA;
• we exclude restructuring expenses from adjusted EBITDA. Restructuring expenses primarily include employee severance and contract termination costs that are not related to acquisitions. The amount and/or frequency of these restructuring expenses are not part of our underlying business;
• we exclude litigation settlements and contingencies that are subject to recovery from adjusted EBITDA, as well as any applicable income items, credit adjustments, or recoveries due to subsequent changes in estimates. This does not include our legal fees to defend claims, which are expensed as incurred;
• we exclude acquisition related expenses as the amount and/or frequency of these expenses are not part of our underlying business. Acquisition related expenses include transaction costs, which primarily consisted of financial advisory, banking, legal, and regulatory fees, and other consulting fees, incurred to complete the acquisition, employee-related expenses (severance cost and benefits) for terminated employees after the acquisition, legal defense expenses for specific acquired claims that relate to acts that occurred prior to our acquisition, and miscellaneous other acquisition related expenses incurred;
• we exclude recognition of the step-up basis in inventory from acquisitions (i.e., the adjustment to record inventory from historic cost to fair value at acquisition) as the adjustment does not reflect the ongoing expense associated with sale of our products as part of our underlying business;
• we exclude changes in the fair value of contingent consideration, which are non‑cash, acquisition‑related items that are not part of our underlying business;
• we exclude losses on extinguishments of debt as these expenses are episodic in nature and do not directly correlate to the cost of operating our business on an ongoing basis;
• we exclude executive transition expenses from adjusted EBITDA as the amount and/or frequency of these expenses are episodic in nature and do not directly correlate to the cost of operating our business on an ongoing basis; and
• we exclude other expenses, from time to time, that are episodic in nature and do not directly correlate to the cost of operating our business on an ongoing basis.

The Company has not provided a reconciliation of its full-year 2026 guidance for adjusted EBITDA to the most directly comparable forward-looking GAAP measures, in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K, because the Company is unable to predict, without unreasonable efforts, the timing and amount of items that would be included in such a reconciliation, including, but not limited to, stock-based compensation expense, acquisition related expenses, amortization of acquired intangible assets, and changes in fair value of contingent consideration. These items are uncertain and depend on various factors that are outside of the Company’s control or cannot be reasonably predicted. While the Company is unable to address the probable significance of these items, they could have a material impact on GAAP net income and operating expenses for the guidance period. A reconciliation of adjusted EBITDA would imply a degree of precision and certainty as to these future items that does not exist and could be confusing to investors.

About AZSTARYS^®

AZSTARYS is a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 6 years and older. The use of AZSTARYS is not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage.

IMPORTANT SAFETY INFORMATION

BOXED WARNING: ABUSE, MISUSE, AND ADDICTION See full prescribing information for complete boxed warning. AZSTARYS has a high potential for abuse, misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including AZSTARYS, can result in overdose and death. Before prescribing, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and families about risks, proper storage, and proper disposal of any unused drug. Frequently monitor for signs and symptoms of abuse, misuse, and addiction throughout treatment.

CONTRAINDICATIONS

• Known hypersensitivity to serdexmethylphenidate, methylphenidate, or product components.
• Concurrent treatment with a monoamine oxidase inhibitor (MAOI), or use of an MAOI within the preceding 14 days.

WARNINGS AND PRECAUTIONS

• Risks to patients with serious cardiac disease: Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmias, coronary artery disease, or other serious cardiac disease.
• Increased blood pressure and heart rate: Monitor blood pressure and pulse.
• Psychiatric adverse reactions: Prior to initiating AZSTARYS, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing AZSTARYS.
• Priapism: If abnormally sustained or frequent and painful erections occur, patients should seek immediate medical attention.
• Peripheral vasculopathy, including Raynaud's Phenomenon: Careful observation for digital changes is necessary during AZSTARYS treatment with ADHD stimulants. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy (5.6)
• Long-term suppression of growth in pediatric patients: Monitor height and weight at appropriate intervals in pediatric patients.
• Acute angle closure glaucoma: AZSTARYS-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist.
• Increased intraocular pressure (IOP) and glaucoma: Prescribe AZSTARYS to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor patients with a history of increased IOP or open angle glaucoma.
• Motor and verbal tics, and worsening of Tourette’s syndrome: Before initiating AZSTARYS, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor patients for the emergence or worsening of tics or Tourette’s syndrome.
• Discontinue treatment if clinically appropriate.

ADVERSE REACTIONS

• The most common adverse reactions (≥5% and twice the rate of placebo) include decreased appetite, decreased weight, nausea, abdominal pain, dyspepsia, vomiting, insomnia, anxiety, affect lability, irritability, dizziness, increased blood pressure, and tachycardia.
