“As we close the chapter on 2020, we reflect on several strategic shifts, including a move toward digital marketing, enhanced patient services, an increasing shift to our hub model, and a leaner operational profile with increased cash. These changes position us to be at the forefront of reinventing specialty pharma through engagement that physicians and patients find convenient and can access during their own time,” said Dan Peisert, President and Chief Executive Officer of Assertio.

“COVID-19 has rapidly accelerated the trend toward virtual engagement. We look forward to sharing more about how we are refining our commercial platform in the near future. We are also actively seeking additional assets that will address unmet needs for patients, be synergistic with our new commercial platform, and bring value to Assertio.”

Full Year 2020 and Subsequent Highlights:

  • Raised $45.3 Million in Cash, Net of Expenses, on Closing of Registered Direct Offerings: On February 9 and February 12, 2021, the Company announced the closing of registered direct offerings that resulted in Assertio receiving $45.3 million in cash, net of expenses. The proceeds from these offerings enhance the Company’s liquidity, accelerate its transformational business plan, and open up new avenues for mergers and acquisitions.
  • Realized $40.0 Million in Annual Cost Savings in 2020, Poised to Realize Additional $45.0 Million of Annualized Cost Savings After One-time Restructuring Costs: Assertio has achieved its stated target of $40.0 million of annual cost savings in 2020 after the closing of its merger with Zyla. The Company also reiterates its confidence in the ability to realize an additional $45.0 million of annualized cost savings, after the effect of one-time restructuring costs.
  • Restructuring: On December 15, 2020, the Company announced a comprehensive restructuring plan designed to further reduce its cost base and right size the organization. The Company realized restructuring charges of $11.2 million in the fourth quarter of 2020 for this plan and expects up to $12.0 million in total, which accounts for additional non-cash charges relating to the write-off of certain office lease and furniture assets.
  • Completed $505.2 Million in Strategic Asset Sales and Repaid $450.2 Million in Debt: In 2020, the Company completed several transactions that monetized its assets and paid down its debt.

    • $505.2 Million in Strategic Asset Sales

      - NUCYNTA® Franchise for $369.0 Million: On February 13, 2020, The Company completed the sale of the NUCYNTA franchise to Collegium for a total value of $369.0 million, including inventory and less royalties paid to Assertio in 2020.

      - Sale of Gralise® for $130.3 Million: On January 10, 2020, the Company completed the sale of Gralise to Alvogen for a total value of $130.3 million, including inventory.

      - Convertible Debt of $264.7 Million: With two separate transactions on February 19, 2020 and April 9, 2020, the Company retired substantially all of its $265.0 million outstanding Convertible Notes via privately negotiated purchase agreement and a tender.

      - Zyla Debt of $13.0 Million: Upon close of the Zyla merger on May 20, 2020, $13.0 million of Zyla’s debt was extinguished.

      - Prepayment of $10.0 Million of Current Senior Secured Debt: The Company prepaid $10.0 million of debt principal in July.
  • Efficient Merger Integration: The Company closed its merger with Zyla on May 20, 2020 and completed the integration of the two companies within a timeline of less than 12 weeks.
  • Continued Transition to Hub Model from Traditional Retail: Throughout 2020, the Company has increased the momentum in the transition of its business to a Hub Model from a traditional retail focus, resulting in increased profit per prescription.

COVID-19 Update

Following the outbreak of COVID-19 during early 2020, the Company’s priority was and remains the health and safety of its employees, their families, and the patients it serves. As a result, in March 2020, the Company initiated remote working arrangements and maintained flexible work arrangements for individuals, which continued through the remainder of 2020 and into 2021. In addition to the health and safety of its employees, the Company is focused on ensuring that it continues making its products accessible to the patients who need them. Because COVID-19 impacted its ability to see in-person providers who prescribe its products, the Company adapted its approach during 2020 and increased its virtual visits. Additionally, due to the limitations on elective surgeries, the Company has experienced a decline in prescriptions associated with those elective procedures.

Accordingly, given recent unfavorable changes in its product payor mix, as well as the continued near-term impact from the COVID-19 pandemic, the Company implemented a restructuring plan in December 2020 which, it believes, allows the business to continue to provide its differentiated products to patients and better positions itself for future success. The Company believes that it is prepared with sufficient product inventory, technology to facilitate virtual and / or digital communications, and operations prepared to adapt its work environment as needed. The extent to which its operations may continue to be impacted by the COVID-19 pandemic will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the outbreak, actions by government authorities to contain the outbreak or treat its impact, and the distribution, efficacy and public acceptance of COVID-19 vaccines.

Non-GAAP Financial Measures
To supplement the Company’s financial results presented on a U.S. generally accepted accounting principles (GAAP) basis, the Company has included information about non-GAAP measures of EBITDA and adjusted EBITDA as useful operating metrics. The Company believes that the presentation of these non-GAAP financial measures, when viewed with results under GAAP and the accompanying reconciliation, provides supplementary information to analysts, investors, lenders, and the Company’s management in assessing the Company’s performance and results from period to period. The Company uses these non-GAAP measures internally to understand, manage and evaluate the Company’s performance, and in part, in the determination of bonuses for executive officers and employees. These non-GAAP financial measures should be considered in addition to, and not a substitute for, or superior to, net income (loss) or other financial measures calculated in accordance with GAAP. Non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, non-GAAP measures used by other companies.

Specified Items
Non-GAAP measures presented within this release exclude specified items. The Company considers specified items to be significant income/expense items not indicative of current operations. Specified items include: interest expense; income tax expense (benefit); depreciation expense; amortization expense; adjustments to sales reserves for products the Company is no longer selling; non-cash adjustments to Collegium agreement revenue and cost of sales; amortization of fair value inventory step-up as result of purchase accounting; transaction-related costs; legal costs and expenses incurred in connection with opioid-related litigation, investigations and regulations pertaining to the Company’s historical commercialization of opioid products; non-cash gains or losses from adjustments to long-lived assets, intangible assets, goodwill and assets not part of current operations; gains or losses resulting from debt refinancing or extinguishment; stock-based compensation expense; restructuring and related costs; fair value adjustments to contingent consideration and investments; and gains or losses from sale of assets.

Pro forma Items
The Company is providing non-GAAP pro forma net product sales to show the net product sales as if the Zyla Merger had been completed as of January 1, 2019, and therefore the Company operated on a combined basis, including Zyla, for the entirety of 2019 and 2020 periods presented in this release. The Company believes this supplemental information is useful to help investors understand the results of the combined operations, including Zyla and the divestiture of NUCYNTA and Gralise, and assess the Company’s performance from period to period. Supplemental unaudited proforma information is based upon accounting estimates and judgments that the Company believes are reasonable. This supplemental unaudited pro forma financial information has been prepared for comparative purposes only, and is not necessarily indicative of what actual results would have occurred, or of results that may occur in the future.
