LAUSANNE, Switzerland, March 10, 2026 /PRNewswire/ — ADC Therapeutics SA (NYSE: ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today reported financial results for the fourth quarter and full year ended December 31, 2025, and provided recent operational updates. “Building off the meaningful progress achieved across our ZYNLONTA clinical program in DLBCL and through investigator-initiated trials in indolent lymphomas this past year, we believe we have laid the foundation for multiple anticipated value-creating catalysts,” said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. “We expect topline LOTIS-5 results in the second quarter, followed by full LOTIS-5 and LOTIS-7 results in 2L+ DLBCL by the end of 2026 and, assuming positive data, potential compendia inclusions in first half of 2027 with LOTIS-5 regulatory approval to follow. Supported by an expected cash runway at least into 2028, we are confident we will drive significant potential long-term growth beginning in 2027.” Fourth Quarter 2025 Operational Updates and Upcoming Milestones LOTIS-5 topline results anticipated in 2Q 2026. The Company expects to provide topline data in 2Q 2026 from the LOTIS-5 Phase 3 confirmatory trial of ZYNLONTA® (loncastuximab tesirine-lpyl) in combination with rituximab in patients with 2L+ diffuse large B-cell lymphoma (DLBCL) once the pre-specified number of approximately 262 progression-free survival events is reached and data are available. Full results are anticipated to be published by the end of 2026. Assuming positive results, the Company will file a supplemental Biologics License Application (sBLA) submission with the U.S. Food and Drug Administration (FDA), with potential compendia inclusion in the first half of 2027 and confirmatory approval in 2L+ DLBCL to follow in mid-2027. LOTIS-7 trial ongoing with data anticipated by year-end. In December 2025, the Company reported updated data from the LOTIS-7 Phase 1b trial evaluating ZYNLONTA in combination with the bispecific antibody glofitamab (COLUMVI®) in patients with relapsed or refractory (r/r) DLBCL. The data demonstrated an 89.8% best overall response rate and a 77.6% complete response rate across 49 efficacy evaluable patients with a minimum of six months follow-up. The LOTIS-7 trial is ongoing at the selected 150 µg/kg dose and the Company plans to share full data at a medical meeting and through publication by the end of 2026. The Company plans to assess regulatory and compendia strategies. Ongoing investigator-Initiated trials (IITs) evaluating ZYNLONTA in additional B-cell malignancies. The Company anticipates publication of data from the University of Miami Sylvester Comprehensive Cancer Center-led multi-center trials of ZYNLONTA in combination with rituximab to treat r/r follicular lymphoma (FL) and as a monotherapy to treat marginal zone lymphoma (MZL) between the end of 2026 and mid-2027. Assuming positive data, the Company intends to assess potential regulatory and compendia pathways. Fourth Quarter and Full Year 2025 Financial Results Product Revenues: Net product revenues were $22.3 million and $73.6 million for the fourth quarter and full year ended December 31, 2025, as compared to $16.4 million and $69.3 million for the same periods in 2024. The quarter-over-quarter increase in revenue primarily reflected variability in customer ordering, with underlying demand broadly stable. The increase for the full year was driven by higher selling price and relatively flat volume year-over-year. Research and Development (R&D) Expense: R&D expense was $18.2 million and $104.0 million for the fourth quarter and full year ended December 31, 2025, respectively. This compares to R&D expense of $27.1 million and $109.6 million for the same periods in 2024. The decrease in R&D costs quarter-over quarter was primarily driven by a reduction in spending on discontinued programs and completion of the IND-enabling activities for our PSMA-targeting ADC. The decrease in R&D costs for the full year was driven by a reduction in spending on discontinued programs, partially offset by expenditure associated with completion of the IND-enabling activities for our PSMA-targeting ADC and our ongoing ZYNLONTA clinical trials. Selling and Marketing (S&M) Expense: S&M expense was $12.0 million and $43.4 million for the fourth quarter and full year ended December 31, 2025, respectively. This compares to S&M expense of $11.3 million and $44.0 million for the same periods in 2024. S&M expense remained relatively flat period-over-period. General & Administrative (G&A) Expense: G&A expense was $9.5 million and $36.6 million for the fourth quarter and full year ended December 31, 2025, respectively. This compares to G&A expense of $9.6 million and $41.9 million for the same periods in 2024. G&A expense remained relatively flat quarter-over-quarter. The reduction in G&A expense for the full year was primarily due to lower external professional fees. Restructuring, impairment and other related costs: In connection with the strategic reprioritization and restructuring plan announced in June 2025, the Company incurred $0.3 million in income for the fourth quarter and $13.1 million in restructuring, impairment and other related costs for the full year ended December 31, 2025, which consisted of $6.0 million in employee severance and related benefit costs, $5.8 million in non-cash impairment of assets and $1.3 million in dilapidations, lease termination, legal fees, and other related costs in connection with the closure of the UK facility. Total operating expenses and adjusted total operating expenses: Total operating expenses were $41.0 million and $202.9 million for the fourth quarter and full year ended December 31, 2025, respectively, as compared to $49.3 million and $201.5 million for the fourth quarter and full year ended December 31, 2025, respectively. On a non-GAAP basis, total adjusted operating expenses were $39.4 million and $181.3 million for the quarter and full year ended December 31, 2025, respectively, as compared to $46.6 million and $193.8 million for the quarter and full year ended December 31, 2024, respectively. The reduction in total adjusted operating expenses for the fourth quarter was primarily driven by lower R&D expenses. The decrease in total adjusted operating expenses for the full year was a result of lower R&D, G&A and S&M expenses. Net Loss: Net loss for the quarter ended December 31, 2025, was $6.4 million, or a net loss of $0.04 per basic and diluted share, as compared to net loss of $30.7 million, or a net loss of $0.29 per basic and diluted share for the same period in 2024. Net loss for the full year ended December 31, 2025, was $142.6 million, or a net loss of $1.12 per basic and diluted share, as compared to net loss of $157.8 million, or a net loss of $1.62 per basic and diluted share for the full year ended December 31, 2024. The lower net loss over both periods was primarily due to a higher cumulative catch-up adjustment gain associated with our deferred royalty obligation and reduced R&D expense, partially offset by the restructuring, impairment and related costs incurred in connection with the strategic reprioritization and restructuring plan. Adjusted Net Loss: Adjusted net loss, which is a non-GAAP financial measure, was $13.5 million, or an adjusted net loss of $0.09 per basic and diluted share for the quarter ended December 31, 2025, as compared to an adjusted net loss of $26.5 million, or $0.25 per basic and diluted share, for the same period in 2024. Adjusted net loss for the full year ended December 31, 2025, was $91.7 million, or an adjusted net loss of $0.72 per basic and diluted share, as compared to net loss of $111.4 million, or an adjusted net loss of $1.15 per basic and diluted share for the full year ended December 31, 2024. The decrease in adjusted net loss over both periods was due to lower operating expenses and a higher number of weighted average shares outstanding. Cash and cash equivalents: As of December 31, 2025, cash and cash equivalents were $261.3 million, compared to $250.9 million as of December 31, 2024, providing expected cash runway at least into 2028. The Company significantly strengthened its cash and cash equivalents position by entering into a $100 million PIPE financing in June 2025 and a $60.0 million PIPE financing in October 2025 with certain institutional investors, which raised $150.8 million in total after deducting placement agent fees and offering expenses. Subsequent event Amended HealthCare Royalty Financing Agreement. In February 2026, ADC Therapeutics entered into an amendment to its royalty purchase agreement with entities managed by HealthCare Royalty, offering greater strategic flexibility to the Company. The new agreement reduces the change of control payment from $750 million to $150 million through the end of 2027, and to $200 million thereafter. In the event of a change of control, HealthCare Royalty will continue to receive royalties on sales by the acquirer until the original royalty cap is reached. In return, HealthCare Royalty has been granted warrants to purchase approximately 9.8 million common shares, with an exercise price of $3.81 per share. These warrants are exercisable until December 31, 2030, and are subject to a lock-up through the end of 2027.

(i) |
Share-based compensation expense represents the cost of equity awards issued to our directors, management and employees. The fair value of awards is computed at the time the award is granted and is recognized over the requisite service period less actual forfeitures by a charge to the statement of operations and a corresponding increase in additional paid-in capital within equity. These accounting entries have no cash impact. |
|
(ii) |
Change in the fair value of the Deerfield warrant obligation results from the valuation at the end of each accounting period. There are several inputs to these valuations, but those most likely to result in significant changes to the valuations are changes in the value of the underlying instrument (i.e., changes in the price of our common shares) and changes in expected volatility in that price. These accounting entries have no cash impact. |
|
(iii) |
Effective interest expense on senior secured term loans relates to the increase in the value of our loans in accordance with the amortized cost method. |
|
(iv) |
Deferred royalty obligation interest expense relates to the accretion expense on our deferred royalty obligation pursuant to the royalty purchase agreement with HCR and cumulative catch-up adjustments related to changes in the expected payments to HCR based on a periodic assessment of our underlying revenue projections. |
|
(v) |
Restructuring charges consist primarily of employee severance, contract termination costs and other costs associated with the strategic reprioritization and restructuring plan approved by the Board of Directors on June 11, 2025 (“2025 Restructuring”). |
|
(vi) |
Impairment charges consist of write downs of long-lived and prepaid assets associated with the 2025 Restructuring. These accounting entries have no cash impact. |
