**STOUGHTON, Mass., May 7, 2026** -- Collegium Pharmaceutical, Inc. (Nasdaq: COLL) today reported its financial results for the quarter ended March 31, 2026, and provided a business update.

"In the first quarter, we made meaningful progress on our 2026 strategic priorities, including delivering strong performance for JORNAY PM and continued durability from our pain portfolio" said Vikram Karnani, President and Chief Executive Officer. "We generated additional growth for JORNAY PM, with net revenue up 36% and prescriptions rising 14% driven by gains in both new prescribers and market share. We are encouraged by the impact of our expanded ADHD salesforce and marketing initiatives and look forward to integrating AZSTARYS following the expected close of the transaction. The pending acquisition of AZSTARYS represents an important next step in strengthening our ADHD portfolio, extending revenues into the late 2030s, and expanding our growth profile. At the same time, our pain portfolio delivered another solid quarter of durable revenues, driven by differentiated products and deliberate actions taken to enhance profitability. We remain focused on executing our strategy to build a leading diversified biopharmaceutical company while improving the lives of people living with serious medical conditions."

"We delivered strong first quarter results, marked by significant net revenue growth for JORNAY PM, robust contributions from our pain portfolio, and impressive operating cash flows," said Colleen Tupper, Chief Financial Officer. "Our strong financial position enabled us to continue to execute on our capital deployment strategy, fueling the proposed acquisition of AZSTARYS. We expect the acquisition to be immediately accretive upon close and to extend our revenues into the late 2030s. Following an encouraging start to the year, we are well positioned to achieve our strategic priorities and financial commitments as we work to drive long-term shareholder value."

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adjusted EBITDA does not reflect changes in, or cash requirements for, working capital needs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adjusted EBITDA does not reflect the benefit from or provision for income taxes or the cash requirements to pay taxes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we exclude litigation settlements and contingencies that are subject to recovery from adjusted EBITDA, as well as any applicable income items or, 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)The income tax effect of the adjustments was calculated by applying our blended federal and state statutory rate to the items that have a tax effect. The blended federal and state statutory rate for the three months ended March 31, 2026 and 2025 were 24.9% and 25.8%, respectively. As such, the non-GAAP effective tax rates for the three months ended March 31, 2026 and 2025 were 25.4% and 25.4%, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Adjusted weighted-average shares - diluted were calculated using the "if-converted" method for our convertible notes in accordance with ASC 260, *Earnings per Share*. As such, adjusted weighted-average shares – diluted includes shares related to the assumed conversion of our convertible notes and the associated cash interest expense is added-back to non-GAAP adjusted net income. For the three months ended March 31, 2026 and 2025, adjusted weighted-average shares – diluted includes 6,606,305 shares attributable to our convertible notes. In addition, adjusted earnings per share includes other potentially dilutive securities to the extent that they are not antidilutive.

These and other risks are described under the heading "Risk Factors" in our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q and other filings with the SEC. Any forward-looking statements that we make in this presentation speak only as of the date of this presentation. We assume no obligation to update our forward-looking statements whether as a result of new information, future events or otherwise, after the date of this presentation. 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 presentation, we discuss the following financial measures that are not calculated in accordance with GAAP, to supplement our consolidated financial statements presented on a GAAP basis. 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 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. Adjusted Operating Expenses Adjusted operating expenses is a non-GAAP financial measure that represents GAAP operating expenses adjusted to exclude stock-based compensation expense, and other adjustments to reflect changes that occur in our business but do not represent ongoing operations. Adjusted Net Income and Adjusted Earnings Per Share Adjusted net income is a non-GAAP financial measure that represents GAAP net income or loss adjusted to exclude significant income and expense items that are non-cash or not indicative of ongoing operations, including consideration of the tax effect of the adjustments. Adjusted earnings per share is a non-GAAP financial measure that represents adjusted net income per share. Adjusted weighted-average shares - diluted is calculated in accordance with the treasury stock, if-converted, or contingently issuable accounting methods, depending on the nature of the security. Reconciliations of adjusted EBITDA to the most directly comparable GAAP financial measures are included in this presentation. 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, and litigation settlements. 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. 2
