## Exhibit 99.1

**Exhibit 99.1**

## Eikon Therapeutics Reports First Quarter 2026 Financial Results and Provides Clinical Updates
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Maintained strong financial position with $596 million in cash, cash equivalents and marketable securities as of March 31, 2026*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Continued execution across the oncology pipeline, with a strategic focus on three priority programs: EIK1001, a Toll-like receptor 7/8 (TLR7/8) agonist, EIK1003, a next-generation, highly selective PARP1 inhibitor, and EIK1005, a WRN helicase inhibitor*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Six abstracts accepted for the American Society of Clinical Oncology (ASCO) annual meeting highlighting new data from the company's lead programs including new safety, tolerability, and efficacy data* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Publication of a manuscript in the Journal of Medicinal Chemistry on the use of single molecule tracking (SMT) to advance chemical matter for discovery programs in the absence of robust biochemical assays*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Roger M. Perlmutter, Board Chair and CEO, to participate in the Bank of America Securities 2026 Global Healthcare Conference in Las Vegas, May 12, 2026*

**MILLBRAE, Calif., May 11, 2026 --** Eikon Therapeutics, Inc. (Nasdaq: EIKN) ("Eikon"), a late-stage clinical biopharmaceutical company dedicated to developing innovative medicines to address serious unmet medical needs, today reported first quarter 2026 financial results and provided updates on its lead clinical programs.

"We made meaningful progress in the first quarter advancing our oncology programs and expanding the clinical evidence supporting their potential," said Roger M. Perlmutter, M.D., Ph.D., Chief Executive Officer and Board Chair of Eikon Therapeutics. "We are particularly encouraged by the breadth of data emerging across our pipeline, which will be featured at the ASCO annual meeting, and we believe these programs are well positioned to address important unmet needs in oncology. With a strong balance sheet, we remain focused on disciplined execution as we advance toward additional clinical milestones this year."

**Clinical Updates**

Eikon continues to advance its lead programs and reports the following updates through the end of the first quarter of 2026:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**EIK1001** is a systemically administered dual-agonist of Toll-like receptors 7 and 8 designed to stimulate both innate and adaptive immune responses. Phase 1 studies have previously shown that EIK1001 exhibits single-agent activity in patients with advanced malignancy. This mechanism may complement the antitumor immune response engendered by PD-(L)1 blockade. The program continues to advance across multiple clinical trials in melanoma and non-small cell lung cancer ("NSCLC"). Three abstracts have been accepted for presentation at the American Society of Clinical Oncology ("ASCO") annual meeting, including an updated data set from a now fully enrolled Phase 2 trial evaluating EIK1001 in combination with pembrolizumab and chemotherapy for NSCLC. The updated data set includes a full interim data readout of the non-squamous cohort and a partial interim data readout of the squamous cohort. In addition, we expect to make a Trial-in-Progress presentation to highlight an ongoing Phase 2/3 trial of EIK1001 in combination with pembrolizumab for advanced melanoma, as well as the initiation of a Phase 2/3 trial in combination with pembrolizumab and chemotherapy for stage 4 NSCLC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**EIK1003** is a next-generation, highly selective PARP1 inhibitor that has been observed to leave PARP2 signaling intact. PARP2 inhibition may be a key driver of the hematological toxicity associated with first

------

generation, non-selective PARP inhibitors. The program is advancing through an ongoing Phase 1/2 trial in patients with breast, ovarian, prostate, or pancreatic cancer. An abstract has been accepted for presentation at the ASCO annual meeting, including updated data from Cohort 1A evaluating EIK1003 as a monotherapy and Cohort 1C evaluating EIK1003 in combination with paclitaxel in patients with platinum-resistant ovarian cancer, or breast cancer patients who are either Her-2 negative, ER+, and hormonal therapy-experienced, or ER- and chemotherapy-experienced. The dose escalation portion of the trial has been completed for Cohorts 1A, 1B (in prostate cancer patients in combination with the novel hormonal agent, abiraterone, and prednisone), and 1C, with backfill nearing completion. Separately, the first patient has been dosed in a Phase 2 dose optimization trial. In addition, global site selection has been initiated for Cohort 1D, which will evaluate EIK1003 in combination with paclitaxel and platinum-based chemotherapeutic agents in patients with breast or ovarian cancer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**EIK1005** is a WRN helicase inhibitor with demonstrated in vitro activity in MSI-high cancer cells. EIK1005 was optimized using Eikon's technology platform, which includes its imaging instruments that permit single molecule tracking in living cells. The program has advanced into clinical development, with a Phase 1/2 trial underway in patients with advanced solid tumors, which began dosing in February 2026. Two abstracts have been accepted for presentation or publication at the ASCO annual meeting, including data on pharmacokinetics and pharmacodynamics in healthy volunteers and resulting dose modeling, as well as a Trial-in-Progress presentation for the ongoing Phase 1/2 trial.

**First Quarter 2026 Financial Results** 

**Cash Position:** As of March 31, 2026, Eikon had cash, cash equivalents, and marketable securities of $596.0 million. Eikon expects its current cash, cash equivalents, and marketable securities, to fund operations into the second half of 2027.

**Research and Development ("R&D") expenses:** R&D expenses were $70.0 million for the first quarter of 2026 compared to $56.6 million for the first quarter of 2025, an increase of $13.5 million, or 24%. The increase was primarily due to accelerating clinical trial activity and a $5.0 million milestone payment to Impact Therapeutics (Shanghai) Inc. in the first quarter of 2026 for advancement of EIK1003 into Phase 2 development.

**General and Administrative ("G&A") expenses:** G&A expenses were $17.3 million for the first quarter of 2026 compared to $14.8 million for the first quarter of 2025, an increase of $2.5 million, or 17%. The increase was primarily due to higher depreciation expense following the occupation of Eikon's Millbrae headquarters in April 2025 and higher professional fees, insurance expenses, and recruitment fees.

**Net Loss:** Net loss attributable to common stockholders was $83.0 million for the first quarter of 2026, as compared to $74.5 million for the prior-year period.

HRRD = Sensitive Selective EIK1003: Eikon's PARP1 selective inhibitor has potential to overcome current limitations and expand usage setting PARP1 inhibition and subsequent trapped PARP1 leads to DNA double strand breaks In HR competent cells, DSBs are repaired, in HR deficient cells, DNA damage accumulates driving cell death EIK1003 is designed to be highly selective for PARP1 over PARP2, in contrast to currently approved agents PARP2 activity is thought to be a major driver of hematotoxicity Observed improved tolerability could provide potential for use beyond maintenance setting (Lynparza's, the leading PARP inhibitor, current usage maintenance setting yielded $3.7B1 in 2024 revenue) and in combination with chemotherapy 1: AstraZeneca FY 2024 results; HR: homologous recombination; HRRD: HRR deficient

Improved PARP1 selectivity may mitigate liabilities of currently approved agents Normal Hematopoiesis Anemia (reduced red blood cells), neutropenia (low neutrophils) and thrombocytopenia (reduction in platelets) are all associated with the use of non-selective PARP inhibitors 1.
