**STOUGHTON, Mass., February 23, 2023** – Collegium Pharmaceutical, Inc. (Nasdaq: COLL), a leading, diversified specialty pharmaceutical company committed to improving the lives of people living with serious medical conditions, today reported its financial results for the quarter and full-year ended December 31, 2022 and provided a corporate update.

"2022 was a pivotal year for Collegium Pharmaceutical. We acquired and seamlessly integrated BDSI, recognizing approximately $85 million in annual run-rate synergies; renegotiated Xtampza ER contracts, significantly reducing gross-to-net while maintaining broad access; and resolved all 27 opioid industry-related lawsuits brought against the Company," said Joe Ciaffoni, President, and Chief Executive Officer of Collegium. "We expect 2023 to be a banner year highlighted by an acceleration of top- and bottom- line growth as we capitalize on lower Xtampza ER<sup>®</sup> gross-to-net and grow Xtampza ER and Belbuca<sup>®</sup> prescriptions on a full-year basis. We are committed to executing on our strategic priorities, including deploying capital in a disciplined manner, to create long-term value for shareholders."

"Our fourth quarter results demonstrate Collegium's financial strength as we delivered record net revenue, record adjusted EBITDA and robust operating cash flows," said Colleen Tupper, Chief Financial Officer of Collegium. "We returned $19.1 million of capital to shareholders in 2022 and remain committed to strategically deploying capital with business development as our top priority, followed by rapid debt paydown and returning capital to shareholders through our $100 million share repurchase program. Our 2023 financial guidance conveys our confidence that 2023 will be a banner year."

**Full Year 2022 and 2023 Business Highlights**

● Completed Xtampza ER contract renegotiations, maintaining broad access while significantly decreasing rebates; Xtampza ER gross-to-net is expected to be in the range of 61% to 63% in 2023.

● Acquired and seamlessly integrated BDSI and achieved annual run-rate synergies of approximately $85 million.

● Returned $19.1 million in capital to shareholders in 2022, including $7.6 million in the quarter ended December 31, 2022, under the share repurchase program authorized by Collegium's Board of Directors in August 2021.

● Authorized a new share repurchase program in January 2023 to repurchase up to $100 million in common stock.

● Completed a $241.5 million convertible senior note offering due in 2029. Net proceeds from the notes were used to partially repurchase outstanding convertible senior notes due in 2026 and the remainder of the net proceeds are expected to be used for general corporate purposes, including implementation of Collegium's capital deployment strategy.

● Achieved dismissal, pursuant to a master settlement agreement, of all 27 opioid industry-related lawsuits brought against the Company by cities, counties, and other subdivisions in the United States, in March 2022.

● Announced the Federal Circuit's decision upholding the judgment of the U.S. District Court for the District of Delaware regarding the validity of certain claims of the patents protecting Belbuca in December 2022. Collegium expects that, by virtue of the Federal Circuit's decision, Alvogen will be barred from entering the market with its product until 2032.

● Issued inaugural environmental, social and governance (ESG) report in February 2023.

**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 use these non-GAAP financial measures to understand, manage and evaluate our business as we believe they provide additional information on the performance of our business. We believe that the presentation of these non-GAAP financial measures, taken in conjunction with our results under GAAP, provide analysts, investors, lenders and other third parties insight into our view and assessment of our ongoing operating performance. In addition, we believe that the presentation of these non-GAAP financial measures, when viewed with our results under GAAP and the accompanying reconciliations, provide supplementary information that may be useful to analysts, investors, lenders, and other third parties in assessing our performance and results from period to period. We report these non-GAAP financial measures to portray the results of our operations prior to considering certain income statement elements. These non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, net income or other financial measures calculated in accordance with GAAP.

In our quarterly and annual reports, earnings press releases and conference calls, we may 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 (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 (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;

● we exclude stock-based compensation expense from adjusted EBITDA although (a) 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 (b) 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;

● 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 impairment expenses from adjusted EBITDA and, although these are non-cash expenses, the asset 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 from adjusted EBITDA, as well as any applicable income items or credit adjustments 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, and miscellaneous other acquisition related expenses incurred; and

● 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.

*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 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, adjusted operating expenses, adjusted net income, and adjusted earnings per share to the most directly comparable GAAP financial measures are included in this press release.

The Company has not provided a reconciliation of its full-year 2023 guidance for adjusted EBITDA or adjusted operating expenses 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 expense 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 or adjusted operating expenses 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 of 26% to the items that have a tax effect. As such, the non-GAAP effective tax rates for the three months ended December 31, 2022 and 2021 were 25.4% and 24.8%, respectively, and the non-GAAP effective tax rates for the years ended December 31, 2022 and 2021 were 25.4% and 22.8%, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Adjusted weighted-average shares - diluted were calculated using the "if-converted" method for the convertibles notes in accordance with ASC 260, *Earnings per Share*. As such, for periods where non-GAAP adjusted income (loss) was in an income position, adjusted earnings per share includes 4,925,134 shares related to the assumed conversion of the convertible notes and the associated cash interest expense added-back to non-GAAP adjusted net income, as well as other potentially dilutive securities to the extent that they are not antidilutive.

We use these non-GAAP financial measures to understand, manage and evaluate our business as we believe they provide additional information on the performance of our business. We believe that the presentation of these non-GAAP financial measures, taken in conjunction with our results under GAAP, provide analysts, investors, lenders and other third parties insight into our view and assessment of our ongoing operating performance. In addition, we believe that the presentation of these non-GAAP financial measures, when viewed with our results under GAAP and the accompanying reconciliations, provide supplementary information that may be useful to analysts, investors, lenders, and other third parties in assessing our performance and results from period to period. We report these non-GAAP financial measures to portray the results of our operations prior to considering certain income statement elements. These non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, net income or other financial measures calculated in accordance with GAAP. 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 (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 (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; • we exclude stock-based compensation expense from adjusted EBITDA although (a) 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 (b) 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; • 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 impairment expenses from adjusted EBITDA and, although these are non-cash expenses, the asset 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 from adjusted EBITDA, as well as any applicable income items or credit adjustments 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, and miscellaneous other acquisition related expenses incurred; and • 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. 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 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, adjusted operating expenses, adjusted net income, and adjusted earnings per share to the most directly comparable GAAP financial measures are included in this presentation. The Company has not provided a reconciliation of its full-year 2023 guidance for adjusted EBITDA or adjusted operating expenses 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 expense 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 or adjusted operating expenses would imply a degree of precision and certainty as to these future items that does not exist and could be confusing to investors. |

Reconciliation of GAAP Net Income to Adjusted Net Income and Adjusted Earnings Per Share (in thousands, except share and per share amounts) (unaudited) 1. The income tax effect of the adjustments was calculated by applying our blended federal and state statutory rate of 26% to the items that have a tax effect. As such, the non-GAAP effective tax rates for the three months ended December 31, 2022 and 2021 were 25.4% and 24.8%, respectively, and the non-GAAP effective tax rates for the years ended December 31, 2022 and 2021 were 25.4% and 22.8%, respectively. 2. Adjusted weighted-average shares - diluted were calculated using the "if-converted" method for the convertibles notes in accordance with ASC 260, Earnings per Share. As such, for periods where non-GAAP adjusted income (loss) was in an income position, adjusted earnings per share includes 4,925,134 shares related to the assumed conversion of the convertible notes and the associated cash interest expense added-back to non-GAAP adjusted net income, as well as other potentially dilutive securities to the extent that they are not antidilutive. 22 GAAP net (loss) income $(7199) $(25034) $(25002) $71,517 Adjustments: Non-cash interest expense 2,383 779 8,285 3,406 Amortization 37,493 16,795 131,469 67,181 Impairment expense 4,786 — 4,786 — Stock-based compensation expense 5,670 4,912 22,874 24,255 Restructuring — 4,578 — 4,578 Litigation settlements — 2,935 — 2,935 Acquisition related expenses 88 — 31,297 — Recognition of step-up basis in inventory 15,824 — 39,584 — Discrete deferred tax benefit from valuation allowance release — — — (62649) Income tax effect of above adjustments (1) (16855) (7445) (60553) (9071) Total adjustments $49,389 $22,554 $177,742 $30,635 Non-GAAP adjusted net income (loss) $42,190 $(2480) $152,740 $102,152 Adjusted weighted-average shares — diluted (2) 39,644,115 34,123,309 39,531,814 41,045,805 Adjusted earnings (loss) per share (2) $1.09 $(0.07) $3.96 $2.58 Three Months Ended December 31, Years Ended December 31, 2022 2021 2022 2021 |
