MENLO PARK, Calif., June 25, 2026 /PRNewswire/ -- GRAIL, Inc. (NASDAQ:GRAL), a healthcare company whose mission is to detect cancer early when it can be cured, today announced the closing of its previously announced equity financing with Samsung affiliates including Samsung C&T Corporation.

GRAIL, Inc. is a healthcare company whose mission is to detect cancer early when it can be cured.

Pursuant to the definitive agreement, the Samsung entities invested $110 million in GRAIL through the purchase of shares of GRAIL common stock at a price of $70.05 per share, representing a long-term investment in support of GRAIL's growth and international expansion objectives.

"This investment from the Samsung entities further strengthens our balance sheet and extends our cash runway as we advance key priorities, including securing regulatory approval and reimbursement for Galleri^® in the United States and expanding access to multi-cancer early detection internationally," said Aaron Freidin, Chief Financial Officer of GRAIL. "We are pleased to complete this financing and look forward to deepening our strategic collaboration with Samsung as we work to bring Galleri to patients in Asia."

As previously announced, GRAIL and Samsung C&T Corporation intend to collaborate to commercialize the Galleri multi-cancer early detection test in South Korea, with the potential to expand into additional Asian markets, including Japan and Singapore, subject to regulatory approvals and other conditions. Initial testing will continue to be performed at GRAIL's clinical laboratory in Research Triangle Park, North Carolina.

"GRAIL is at a pivotal moment in its mission to transform early cancer detection. This investment in GRAIL, together with the strategic business collaboration, represents a significant milestone in advancing Samsung C&T's vision expanding access to cancer early detection. We are excited to bring the benefits of innovative screening technologies to more people in South Korea and Asia, and believe this partnership will bring us one step closer to GRAIL and Samsung C&T's shared goal of transforming cancer care through earlier detection," said Jaywoo Kim, Executive Vice President of Life Science Business at Samsung C&T.

Latham & Watkins LLP 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 Galleri^®

The Galleri^® multi-cancer early detection (MCED) test screens for more than 50 cancer types, including many deadly cancers that currently lack screening options, such as pancreatic, ovarian and liver/bile duct cancers¹. The Galleri test is the only MCED test clinically proven through a randomized controlled trial to increase earlier cancer detection (Stage I-III) and reduce Stage IV diagnoses - enabling more patients to have access to potentially curative treatment options². When added to standard-of-care screening, the Galleri test reduced Stage IV diagnosis by more than 20% after the first year of screening across all stageable cancers^2,*. The Galleri test increased cancer detection by screening four times versus standard of care screening alone². The Galleri test has the lowest false positive rate among MCED tests** and the ability to predict the Cancer Signal of Origin with greater than 90% accuracy, helping guide efficient diagnostic evaluation^1-³. The Galleri test is backed by a robust clinical evidence program, with more than 380,000 participants across multiple studies, including the NHS-Galleri trial, the first and only randomized controlled trial for an MCED test. The Galleri test has delivered consistent performance across these studies. 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, cervical or lung cancer screening. The Galleri test is recommended for adults with an elevated risk for cancer, such as those aged 50 or older.

*A statistically significant reduction was not observed in combined stage III–IV diagnoses across three screening rounds for 12 cancer types responsible for around two-thirds of cancer mortality in the US and UK.

**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.
