Overview

We are a fully integrated commercial-stage innovative oncology company with an approved next-generation PD-1 inhibitor, LOQTORZI, and a pipeline that includes two mid-stage clinical candidates targeting liver, lung, head & neck, and other cancers. Our strategy is to expand the use of LOQTORZI in NPC and advance the development of new indications for LOQTORZI in combination with both our pipeline candidates as well as our industry partners, driving synergies from proprietary combinations, including first-in-class anticancer agents. On May 29, 2025 we changed our corporate name from Coherus BioSciences, Inc. to Coherus Oncology, Inc. to better align with our exclusive focus on proprietary innovative immuno-oncology medicines following the completion of the recent divestitures of our biosimilar businesses and the transition to an exclusive focus on immuno-oncology.

We primarily operate in the United States and partner with companies that operate in other countries.

Product and Product Candidates** **

Our portfolio includes the following product and product candidates:

Oncology

On December 11, 2023 we announced that NCCN updated the clinical practice guidelines for NPC to include LOQTORZI as a preferred, category 1 first-line treatment option for adults with metastatic or recurrent locally advanced NPC when used in combination with cisplatin and gemcitabine. On November 26, 2024, NCCN made a further update to the clinical practice guidelines for NPC to specify that LOQTORZI is the only preferred category 1 first-line treatment option for adults with metastatic or recurrent locally advanced NPC when used in combination with cisplatin and gemcitabine. The guidelines also recommend LOQTORZI monotherapy as the only preferred treatment in subsequent lines of therapy with disease progression on or after a platinum-containing therapy.

Further evaluation of LOQTORZI is expected through multiple current and planned clinical studies by us and our partners. We have a post marketing commitment study active and enrolling patients in locations in the U.S. and Canada in order to further evaluate the efficacy of toripalimab in combination with chemotherapy

(cisplatin and gemcitabine) in patients with advanced NPC (clinicaltrials.gov identifier# NCT06457503). Junshi Biosciences is currently enrolling in a multiregional Phase 3 clinical study evaluating the treatment of LOQTORZI with its investigational anti-BTLA antibody in LS-SCLC (clinicaltrials.gov identifier# NCT06095583). INOVIO Pharmaceuticals, Inc. plans a randomized Phase 3 study of INO-3112 and toripalimab in locally advanced, high risk HPV16/18+ oropharyngeal squamous cell carcinoma. Cancer Research Institute plans to evaluate toripalimab in combination with ENB Therapeutics’ investigational agent ENB-003 in its Phase 2 trial titled, “Immunotherapy Platform Study in Platinum Resistant High Grade Serous Ovarian Cancer (IPROC)” (clinicaltrials.gov identifier# NCT04918186) that is being performed in collaboration with Canadian Cancer Trials Group. STORM Therapeutics, Ltd. is evaluating its METTL3 inhibitor STC-15 in combination with LOQTORZI in a Phase 1b/2 study (clinicaltrials.gov identifier# NCT06975293) for the treatment of non-small cell lung cancer and head and neck squamous cell carcinoma (“HNSCC”), and has plans for melanoma and endometrial cancer. On June 27, 2024, we entered into the Canada License Agreement with Apotex, Inc. (“Apotex”), pursuant to which, we granted to Apotex an exclusive license under our rights to toripalimab to commercialize toripalimab within Canada.

License Agreement with Junshi Biosciences

On February 1, 2021, we entered into the Collaboration Agreement with Junshi Biosciences for the co-development and commercialization of LOQTORZI, Junshi Biosciences’ anti-PD-1 antibody in the United States and Canada.

Under the terms of the Collaboration Agreement, we paid $150.0 million upfront for exclusive rights to LOQTORZI in the United States and Canada, an option in these territories to Junshi Biosciences’ anti-TIGIT antibody CHS-006, an option in these territories to a next-generation engineered IL-2 cytokine, and certain negotiation rights to two undisclosed preclinical immuno-oncology drug candidates. On January 10, 2024, we announced that we had delivered a notice of termination of CHS-006 to Junshi Biosciences. We obtained the right to conduct all commercial activities of

LOQTORZI in the United States and Canada. We are obligated to pay Junshi Biosciences up to an aggregate $380.0 million in one-time payments for the achievement of various regulatory and sales milestones, of which we have already paid $25.0 million, and a royalty in the low twenty percent range on net sales of LOQTORZI. On June 27, 2024, we entered into the Canada License Agreement pursuant to which, we granted to Apotex an exclusive license under our rights to toripalimab to commercialize toripalimab within Canada.

Closing of UDENYCA Sale

On December 2, 2024, we and Intas entered into the UDENYCA Purchase Agreement, pursuant to which the Company agreed to divest the UDENYCA Business to Intas. On the UDENYCA Closing Date, we completed the divestiture of the UDENYCA Business to Intas for upfront, all-cash consideration of $483.4 million, inclusive of $118.4 million for UDENYCA product inventory. In addition, we are also eligible to receive two additional Earnout Payments. The first such payment is payable by Intas to us if Net Sales of UDENYCA for four consecutive fiscal quarters from July 1, 2025 through September 30, 2026 are equal to or greater than $300 million, and the second such payment is payable by Intas to us if Net Sales of UDENYCA for four consecutive fiscal quarters from July 1, 2025 through March 31, 2027 are equal to or greater than $350 million.

Revenue Purchase and Sale Agreement

On April 15, 2025, we paid $47.7 million to buy out the Purchaser Group’s right to receive the Revenue Payments with respect to UDENYCA in accordance with the Revenue Purchase and Sale Agreement. The Purchaser Group’s right to receive up to 5.0% of U.S. net sales of LOQTORZI with respect to a specified threshold of LOQTORZI net sales during an applicable year and 0.5% of U.S. net sales of LOQTORZI that exceeded the specified threshold during that year was unaffected by the UDENYCA Sale.

2026 Convertible Notes

On April 1, 2025, we announced we entered into privately negotiated repurchases with certain holders of our 2026 Convertible Notes, pursuant to which we agreed to repurchase certain 2026 Convertible Notes from such holders at a cash repurchase price equal to 100% of their principal amount, together with the accrued and unpaid interest to, but excluding, the date of repurchase. At the closing of these repurchases on April 15, 2025, we repurchased $170.0 million aggregate principal amount of the 2026 Convertible Notes. On May 15, 2025, pursuant to the Fundamental Change Repurchase Right (as defined in the Indenture), we repurchased $59.9 million aggregate principal amount of the 2026 Convertible Notes, at a cash repurchase price of $59.9 million, which amount was equivalent to 100% of the principal amount of the repurchased notes, together with the accrued and unpaid interest. As of June 30, 2025, the outstanding principal amount of the 2026 Convertible Notes was $0.1 million and consisted of the remaining notes that were not tendered for repurchase.

Financial Operations Overview

Discontinued Operations

UDENYCA Sale represented the last and most significant divestiture of the Company’s biosimilar businesses, which comprised the UDENYCA, YUSIMRY and CIMERLI franchises; therefore, the strategic shift criteria had been met. Accordingly, for all prior periods presented, the results of the discontinued operations have been reported as a separate component of income on the condensed consolidated statements of operations, and the assets and liabilities of the discontinued operations have been presented separately in the condensed consolidated balance sheets.

Revenue

LOQTORZI was approved in October 2023 and was launched in the United States in December 2023.

Cost of Goods Sold

Cost of goods sold consists primarily of third-party manufacturing, distribution, royalties and certain overhead costs. Cost of goods sold includes a royalty in the low twenty percent range on net sales of LOQTORZI.

Research and Development Expense

Research and development expense represents costs incurred to conduct research, such as the discovery and development of our product candidates. We recognize all research and development costs as they are incurred. We currently track research and development costs incurred on a product candidate basis only for external research and development expenses. Our external research and development expense consists primarily of:

Internal costs are associated with activities performed by our research and development organization and generally benefit multiple programs. These costs are not separately allocated by product candidate. Unallocated, internal research and development costs consist primarily of:

The process of conducting the necessary clinical research to obtain regulatory approval is costly and time consuming. Furthermore, in the past, we have entered into collaborations with third parties to participate in the development and commercialization of our product candidates, and we may enter into additional collaborations in the future. In situations in which third parties have substantial influence over the development activities for product candidates, the estimated completion dates are not fully under our control. For example, our partners in licensed

territories may exert considerable influence on the regulatory filing process globally. Therefore, we cannot forecast with any degree of certainty the duration and completion costs of these or other current or future clinical trials of our product candidates. We may never succeed in achieving regulatory approval for any of our pipeline product candidates. In addition, we may enter into other collaboration arrangements for our other product candidates, which could affect our development plans or capital requirements.

Selling, General and Administrative Expense

Selling, general and administrative expense consists primarily of personnel costs, allocated facilities costs and other expense for outside professional services, including legal, insurance, human resources, outside marketing, advertising, audit and accounting services, acquisition-related costs, and costs associated with establishing commercial capabilities in support of the commercialization of LOQTORZI. Personnel costs consist of salaries, benefits and stock-based compensation. Reimbursement of expenses from counterparties to the TSAs are recorded as reductions to selling, general and administrative expense.

Interest Expense

Interest expense consists primarily of interest incurred on our outstanding indebtedness, our Revenue Purchase and Sale Agreement, and non-cash interest related to the amortization of debt discount and debt issuance costs associated with our outstanding debt agreements.

Other Income (Expense), Net

Other income (expense), net consists primarily of interest earned on our cash and cash equivalents, non-cash accretion of discount on our investments in marketable securities, foreign exchange gains (losses) resulting from currency fluctuations, gains (losses) from financial instruments including the change in fair value of the Royalty Fee Derivative Liability, gains (losses) from disposal of long-lived assets, and income related to certain services provided under transition service agreements.
