Samsung C&T (SCT), Samsung Electronics (SEC), and GRAIL, Inc. (Nasdaq: GRAL), today announced they have signed a binding Letter of Intent for a strategic collaboration to bring GRAIL’s GalleriⓇ multi-cancer early detection (MCED) test to key Asian markets. SCT and SEC have also agreed to invest $110 million into GRAIL, a healthcare company whose mission is to detect cancer early when it can be cured, at a price of $70.05 per share of common stock.1
"Guided by its commitment to advancing next-generation bio-technologies and improving quality of life, Samsung C&T has continuously invested in innovative companies. The collaboration with GRAIL represents a significant new step—moving beyond investment to a strategic business partnership that provides Samsung with a strong foothold for expanding into the cancer screening field and delivering one of these promising technologies to customers in South Korea and across Asia." said Jaywoo Kim, Executive Vice President of Life Science Business at Samsung C&T.
Subject to final execution of definitive agreements, GRAIL and SCT will work as exclusive partners to commercialize the Galleri test in South Korea, with a possible extension into other Asian geographies, including Japan and Singapore. SCT will undertake key activities to drive adoption of Galleri . Initially, tests will be performed in GRAIL’s clinical laboratory in Research Triangle Park, North Carolina.
“We look forward to partnering with Samsung to bring multi-cancer early detection to Asia, beginning in South Korea,” said Sir Harpal Kumar, President, International Business & Biopharma, at GRAIL. “Samsung’s significant equity investment strengthens our balance sheet and provides further cash runway as we advance through key milestones to secure reimbursement for Galleri in the U.S. and key international markets.”
In addition, SEC and GRAIL intend to explore potential strategic and operational collaborations such as supporting longitudinal genomic-lifestyle clinical research, and the integration of SEC’s health data platform with GRAIL’s technologies and data.
“Our investment in and strategic cooperation with GRAIL is part of our vision to improve the health of billions of people. A potential collaboration with GRAIL could allow for the integration of our AI, our digital care platform, and device ecosystem with GRAIL's clinical genetic data and technology, which could allow us to provide a level of personalization for our users to help them better understand their health,” said Hon Pak, Senior Vice President and Head of Digital Health Team, Mobile eXperience Business, at Samsung Electronics.
The terms of the collaborations are set forth in the term sheets between the parties. Definitive agreements will be negotiated in good faith pursuant to the term sheet and are intended to be entered into in early 2026. Commercial operations will begin soon after execution. Within South Korea, and potentially Japan and Singapore, GRAIL will partner with SCT as its sole distributor, subject to certain requirements, and GRAIL’s Galleri test will be the exclusive MCED test distributed by SCT.
The investment is subject to execution of the definitive collaboration agreements between the parties, as well as customary closing conditions and regulatory approvals. The investment is expected to close in early 2026.
Latham & Watkins served as legal advisor and Morgan Stanley & Co. LLC served as financial advisor to GRAIL. Samsung was advised by Covington & Burling, BKL, and E&Y Han Young (Korea).

About GRAIL
GRAIL is a healthcare company whose mission is to detect cancer early, when it can be cured. GRAIL is focused on alleviating the global burden of cancer by using the power of next-generation sequencing, population-scale clinical studies, and state-of-the-art machine learning, software, and automation to detect and identify multiple deadly cancer types in earlier stages. GRAIL’s targeted methylation-based platform can support the continuum of care for screening and precision oncology, including multi-cancer early detection in symptomatic patients, risk stratification, minimal residual disease detection, biomarker subtyping, treatment and recurrence monitoring. GRAIL is headquartered in Menlo Park, CA with locations in Washington, D.C., North Carolina, and the United Kingdom.

About Galleri®
The Galleri multi-cancer early detection test is a proactive tool to screen for cancer. With a simple blood draw, Galleri can detect more than 50 types of cancer before symptoms appear — when they can be easier to treat and are potentially curable2. Galleri is the only available MCED test with demonstrated performance in patients screened for cancer2,*. The Galleri test doubles the number of cancers detected when added to standard of care cancer screening, and has the lowest false positive rate of any MCED test1,2,3,4,**. When a cancer signal is found, Galleri provides a cancer signal of origin with high accuracy to help guide an efficient diagnostic work-up4,5,6. The Galleri test requires a prescription from a licensed healthcare provider and should be used in addition to recommended cancer screenings such as mammography, colonoscopy, prostate-specific antigen (PSA) test, or cervical cancer screening. The Galleri test is recommended for adults with an elevated risk for cancer, such as those aged 50 or older.

* The Galleri test performance metrics were derived from the outcomes of an interventional clinical study of patients presenting for screening without clinical suspicion of cancer, a study population that reflects the intended use population.
** Test performance metrics do not represent results of a head-to-head comparative study. Separate studies have different designs, objectives, and participant populations, which limits the ability to draw conclusions about comparative performance.
Important Galleri Safety Information
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those age 50 or older. The test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. The Galleri test is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of the test is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.
Results should be interpreted by a healthcare provider in the context of medical history, clinical signs, and symptoms. A test result of No Cancer Signal Detected does not rule out cancer. A test result of Cancer Signal Detected requires confirmatory diagnostic evaluation by medically established procedures (e.g., imaging) to confirm cancer.
If cancer is not confirmed with further testing, it could mean that cancer is not present or testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. False positive (a cancer signal detected when cancer is not present) and false negative (a cancer signal not detected when cancer is present) test results do occur. Rx only.
Laboratory/Test Information
The GRAIL clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988.
(CLIA) and accredited by the College of American Pathologists. The Galleri test was developed — and its performance characteristics were determined — by GRAIL. The Galleri test has not been cleared or approved by the Food and Drug Administration. The GRAIL clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
