Corporate Presentation May 2022

Any historical or projected financial information contained in this presentation are not intended to be indicative of future financial results. The events and circumstances reflected in these forward-looking statements, may not be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. Undue reliance should not be placed on the forward-looking statements. Moreover, we operate in a dynamic industry and economy. New risk factors could emerge from time to time, and it is not possible for our management to predict all uncertainties that the Company may face. Non-GAAP Measures To supplement our financial results determined by U.S. generally accepted accounting principles (“GAAP”), we have included certain non-GAAP information for our business, including EBITDA, as adjusted. We believe this non-GAAP financial measure is helpful in understanding our business as it is useful to investors in allowing for greater transparency of supplemental information used by management. Non-GAAP financial measures should be considered in addition to, but not as a substitute for, reported GAAP results. Please see the “Reconciliation of GAAP to Non-GAAP Financial Measures” at the end of this presentation for a reconciliation of non-GAAP adjusted EBITDA to its most directly comparable GAAP measure. This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements, among other things, relate to the Company’s growth drivers and expected levels of our organic growth; synergies and value creation potential created by our acquisition of IRISYS, LLC (“IRISYS”) (the “Acquisition”); the impact of our investment in development and commercial initiatives; financial guidance, including timing of revenues and EBITDA from the Acquisition; our ability to manage costs and to achieve our financial goals; our ability to operate under increased leverage and associated lending covenants; our ability to pay our debt under our credit agreement and to maintain relationships with CDMO commercial partners and develop additional commercial and development partnerships. The words "anticipate", "believe", "could", "estimate", “upcoming”, "expect", "intend", "may", "plan", "predict", "project", "will" and similar terms and phrases may be used to identify forward-looking statements in this presentation. The forward-looking statements in this presentation are only predictions. Our operations involve risks and uncertainties, many of which are outside our control, and any one of which, or a combination of which, could materially affect our results of operations, and the forward-looking statements contained herein could ultimately prove to be incorrect. Factors that could cause our actual outcomes to differ materially from those expressed in or underlying these forward-looking statements include the ability to successfully integrate IRISYS with the Company (including achievement of synergies and cost reductions), the ongoing economic and social consequences of the COVID-19 pandemic, including any adverse impact on customer ordering patterns or inventory rebalancing or disruption in raw materials or supply chain; demand for our services, which depends in part on customers’ research and development and the clinical plans and market success of their products; customers' changing inventory requirements and manufacturing plans; customers’ and prospective customers’ decisions to move forward with our manufacturing services; the average profitability, or mix, of the products we manufacture; our ability to enhance existing or introduce new services in a timely manner; fluctuations in the costs, availability, and suitability of the components of the products we manufacture, including active pharmaceutical ingredients, excipients, purchased components and raw materials, or our customers facing increasing or new competition. These forward-looking statements should be considered together with the risks and uncertainties that may affect our business or the business of IRISYS and future results presented herein along with those risks and uncertainties discussed in our filings with the Securities and Exchange Commission (the “SEC”) at www.sec.gov. These forward-looking statements are based on information currently available to us, and we assume no obligation to update any forward-looking statements except as required by applicable law.

See reconciliation page 20 of presentation. Q1 2022 financial results Revenues were $21.2 million, an increase of 26% from Q1 2021 EBITDA, as adjusted, was $1.4 million, down $1.3 million from Q1 2021 due to lower than expected sales of Verapamil by our marketing partner, Lannett Gross margin was 24% compared to 14% in Q1 2021 Other highlights Rebranded to Societal CDMO, signifying the organization’s evolving outlook and our approach to doing business Signed multiple new business agreements spanning early stage through commercial manufacturing Launching aseptic fill-finish and lyophilization service in Q2 2022; facilities upgrades continue

Reconciliation of Non-GAAP Financial Measures (unaudited) To supplement our financial results determined by U.S. generally accepted accounting principles (“GAAP”), we have disclosed in the tables below the following non-GAAP information about EBITDA, as adjusted. EBITDA, as adjusted, is net income or loss as determined under GAAP excluding interest, depreciation, amortization, non-cash stock-based compensation, charges related to reductions in force and costs related to the acquisition and integration of IriSys, as well as the impact of Accounting Standards Update 2014-09 in order to remove the impact of the timing of revenue recognized from profit-sharing arrangements upon transfer of control of the product, which more closely aligns revenue with expected cash receipt. We believe that non-GAAP financial measures are helpful in understanding our business as it is useful to investors in allowing for greater transparency of supplemental information used by management. EBITDA, as adjusted, is used by investors, as well as management in assessing our performance. Non-GAAP financial measures should be considered in addition to, but not as a substitute for, reported GAAP results. Further, Non-GAAP financial measures, even if similarly titled, may not be calculated in the same manner by all companies, and therefore should not be compared. To exclude the impact of Accounting Standards Update 2014-09, "Revenue Recognition," related to non-cash changes in our contract asset. Costs related to the acquisition and integration of IriSys. In October 2020, the Company submitted a forgiveness application for its note under the Paycheck Protection Program of the Coronavirus Aid, Relief and Economic Security Act of 2020. In June 2021, the PPP Note and all accrued interest thereon was forgiven. Upon receiving the decision, the Company recorded a gain on extinguishment of debt for the forgiveness of $3,316 of principal and $36 of accrued interest.
