Previous Earnings Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Mar 02 | Q4/FY 2025 earnings | Positive | +0.1% | Revenue growth, lower net loss, royalty financing and Ziihera approvals highlighted. |
| Nov 06 | Q3 2025 earnings | Positive | -8.0% | Higher revenue with milestone and royalty income plus narrowed net loss. |
| Aug 07 | Q2 2025 earnings | Positive | -1.1% | Strong revenue growth, net income, growing cash and global Ziihera approvals. |
| May 08 | Q1 2025 earnings | Positive | -0.1% | Higher revenue from milestones, reduced net loss, solid cash runway guidance. |
| Mar 05 | FY 2024 earnings | Positive | -8.0% | Ziihera accelerated approval, robust cash, active early pipeline development. |
Earnings updates have often seen negative price reactions despite generally constructive fundamentals, with only one of the last five earnings events trading higher the next day.
Across the last five earnings releases from Mar 05, 2025 through Mar 02, 2026, Zymeworks highlighted growing revenue, reduced net losses, expanding cash resources, and milestone-driven income from Ziihera. Despite this, shares typically moved lower the following day, with an average move of about -3.44%. Today’s Q1‑2026 update extends that narrative with lower near-term revenue but strengthened liquidity and clearer visibility on future royalty and milestone streams.
Historical Comparison
Past earnings releases averaged a -3.44% next-day move. A solidly positive reaction to this Q1‑2026 report would mark a stronger response than typical.
Earnings updates show a progression from early Ziihera approvals and heavy losses toward higher revenue, milestone and royalty contributions, and strengthened cash resources supported by royalty financing.
Market Pulse Summary
This announcement combined a sharp revenue step-down with detailed guidance on cost discipline and liquidity of $403.8M, alongside expanding ZW191 data and regulatory momentum for Ziihera with up to $440.0M in potential milestones. Investors may focus on how quickly royalty and milestone streams replace legacy milestone revenue, the execution of the $125.0M buyback, and future clinical updates on ZW191 and RAS-targeting ADCs.

VANCOUVER, British Columbia, May 07, 2026 (GLOBE NEWSWIRE) -- Zymeworks Inc. (Nasdaq: ZYME), a biotechnology company managing a portfolio of licensed healthcare assets, while developing a diverse pipeline of novel, multifunctional biotherapeutics, today reported financial results for the first quarter March 31, 2026 and provided a summary of recent business highlights.
“Having a U.S. PDUFA date established under priority review by the FDA for zanidatamab for the treatment of first-line HER2-positive advanced GEA, represents a significant regulatory and strategic milestone for Zymeworks. Zanidatamab's progress across additional clinical indications continues to highlight the value of our strategy to accumulate long-term cash flows from differentiated assets, whether generated internally or externally, with meaningful clinical and commercial potential. Pending global approvals in GEA, we expect zanidatamab to contribute significant milestone payments and to generate long-term, high-quality royalty revenues,” said Kenneth Galbraith, Chair and Chief Executive Officer of Zymeworks. “Over the past quarter, we have further strengthened our leadership team with the addition of individuals bringing extensive experience in strategic capital allocation, investment execution, and deal-making, enhancing our ability to identify and maximize value for our emerging royalty and R&D portfolios. We look forward to the potential of bringing an important new therapy to patients.”
Recent Developments
Wholly-Owned Programs
In April 2026, we shared new preclinical and clinical data at the American Association for Cancer Research (AACR) Annual Meeting. Presentations included new preclinical combination insights from ZW191, as well as additional clinical data from Part 1 of our Phase 1 trial of ZW191:
- In Part 1 of our Phase 1 trial of ZW191 in platinum resistant ovarian cancer (PROC) patients, ZW191 demonstrated a confirmed objective response rate of
56% across all dose levels, with tumor regression observed in68% of patients and disease control achieved in94% . Notably, ZW191 demonstrated compelling efficacy in the 6.4-9.6 mg/kg dose range regardless of FRα expression, with confirmed objective response rates of61% observed in both ovarian and57% in endometrial cancers, with disease control observed in100% of patients, and no new safety signals. These findings highlight the potential for ZW191 to benefit a broad patient population, including those with low or heterogeneous target expression. In March 2026, we announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to ZW191, for the treatment of patients with advanced or metastatic PROC. - Part 2 of our Phase 1 study evaluating both 6.4 mg/kg and 9.6 mg/kg dose regimens in PROC is fully-enrolled with 60 total patients and remains ongoing.
- ZW191’s differentiated clinical profile in nonclinical studies, including favorable tolerability, bodes well for combination strategies including chemotherapy, targeted therapies, and immunotherapies that are mechanistically supported by preclinical studies.
At AACR, we also presented preclinical data from our emerging RAS inhibitor antibody-drug conjugate (ADC) platform and three novel candidates designed to target treatment of RAS mutated cancers:
- A pan-RASi ADC platform with high anti-tumor activity against RAS-driven cancers
- ZW418, a biparatopic PTK7-targeting ADC incorporating a novel pan-RAS inhibitor payload for the treatment of non-small cell lung cancer (NSCLC)
- ZW427, a Ly6E-targeting ADC bearing a novel pan-RAS inhibitor payload for the treatment of RAS mutated cancers including colorectal, pancreatic, and NSCLC
- ZW439, a novel CLDN18.2-targeting pan-RAS inhibitor ADC for the treatment of RAS mutated pancreatic cancer
“At AACR, our team presented three posters highlighting novel preclinical RAS-targeting ADC candidates, demonstrating the breadth of our capabilities in antibody engineering, linker chemistry, and the development of new proprietary payloads. These programs reflect a modular, highly tunable platform designed to address historically challenging targets. In parallel, updated Phase 1 data for ZW191 continue to reinforce the differentiated profile we have seen to date, with breadth and durability of responses, along with activity across varying levels of FRα expression, that we believe position ZW191 as a potential best-in-class therapy,” stated Adam Schayowitz, Ph.D., MBA., Head of R&D at Zymeworks. “Taken together, these data reflect the strength and scalability of our ADC platform and open up a range of future opportunities for both our ADC platforms and product candidates.”

Pending approval, Jazz expects to commercially launch zanidatamab in the U.S. in this indication. Zymeworks is entitled to receive a
In April 2026, BeOne announced that the U.S. FDA has granted Priority Review to a sBLA for TEVIMBRA® (tislelizumab) in combination with Ziihera and chemotherapy for the first-line treatment of unresectable locally advanced/metastatic HER2+ gastric, gastroesophageal junction, or esophageal adenocarcinoma. In April 2026, BeOne also received acceptance for the filing of the sBLA for zanidatamab by the Center for Drug Evaluation of the China National Medical Products Administration (NMPA) to seek approval for zanidatamab for the first-line treatment for HER2+ locally advanced or metastatic GEA, including cancers of the stomach, gastroesophageal junction, and esophagus. BeOne has also received filing acceptance for an sBLA for tislelizumab by the CDE in China based on the HERIZON-GEA-01 data. Zymeworks is entitled to receive a
In April 2026, Jazz presented three posters and an oral presentation at AACR exploring zanidatamab’s utility across HER2-expressing solid tumors beyond biliary tract cancer and GEA. Jazz also announced that they will present multiple presentations on zanidatamab at the American Society of Clinical Oncology Annual Meeting, including a rapid oral presentation of PD-L1 subgroup data from HERIZON-GEA-01 evaluating zanidatamab combinations, and additional analyses of tolerability, biomarker response and real-world treatment patterns in first-line HER2+ GEA. The second interim overall survival analysis for the HERIZON-GEA-01 trial is expected in mid-2026.

Explanation of Non-GAAP Financial Information
In addition to reporting financial information in accordance with U.S. generally accepted accounting principles (GAAP) in this press release, we have elected to present selected non-GAAP, or adjusted, financial measures on a forward-looking basis. Zymeworks believes that estimated adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense, which are non-GAAP financial measures, may be helpful to investors because they provide consistency and comparability with financial performance across periods. These non-GAAP financial measures are not defined by GAAP and should not be considered as alternatives to operating expenses, research and development expenses, and general and administrative expenses or any other indicators of Zymeworks’ performance required to be reported under GAAP. In addition, other companies, including companies in Zymeworks’ industry, may calculate similarly titled non-GAAP or adjusted measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense as financial measures. Investors and others are encouraged to review Zymeworks’ financial information in its entirety and not rely on a single financial measure. As defined by Zymeworks, adjusted gross operating expense represents the aggregate of adjusted research and development expense and adjusted general and administrative expense, each of which excludes stock-based compensation expense for equity- and liability-classified equity instruments. Zymeworks excludes stock-based compensation expense, which is a non-cash expense, because Zymeworks believes that excluding this item provides meaningful supplemental information regarding operational performance.
A reconciliation of historical adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense to the most directly comparable GAAP measures is set forth below. A reconciliation of anticipated adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense to the most directly comparable GAAP measures is not available without unreasonable effort due to the uncertainty of expenses that may be incurred in the future, and we are also unable to predict the probable significance of such adjusted measures. Accordingly, in reliance on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K, we have not provided a reconciliation for the adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense guidance provided in this press release.
