UPDATES TO INFORMATION ABOUT FREENOME

The following amends and supplements page 232 of the Proxy Statement/Prospectus by adding the underlined bolded text (indicated textually in the same manner as the following example: underlined bolded text) as set forth below:

The last full paragraph under the subsection “SimpleScreen v2 — Comprehensive Upgrade of v1 to Drive Potentially Best-In-Class Performance Amongst Blood-Based CRC Screening Tests” shall be revised to read as follows:

Additional improvements in the updated test included increased sensitivity of 44% for APLs with high-grade dysplasia, a 2.6-fold reduction in the limit of detection, and meaningful improvements in projected patient outcomes (9% reduction in lifetime CRC cases and 10% reduction in CRC deaths). V2 will continue to be evaluated in analytical and clinical validation studies. For example, in July 2026, we announced results from a pivotal clinical validation study that assessed the performance of assay and algorithm improvements. The study successfully met its primary and secondary endpoints. The updated test showed 18.2% sensitivity in detecting advanced precancerous lesions (“APLs”), 41.9% sensitivity for APLs with high-grade dysplasia (“HGD”), and 80.4% sensitivity in detecting CRC, including 52% of Stage I cases (Stage I (T1) 39.9% and Stage I (T2) 81.2%), 100% of Stage II, 97.3% of Stage III and 100% of Stage IV. The results were adjusted to the age and sex distribution of the U.S. Census to better reflect the intended use population, and specificity for no findings on colonoscopy was 90%. The data are preliminary, and management’s review and analysis are ongoing.

The clinical validation of the updated SimpleScreen test includes blinded, previously unevaluated samples from participants who enrolled in PREEMPT CRC -- a prospective, registrational study -- as well as previously tested samples. Conducted at more than 200 sites, the PREEMPT CRC study enrolled 48,995 asymptomatic, average-risk adults between the ages of 45 and 85 scheduled to undergo a screening colonoscopy. The analysis included more than 85 individuals with CRC, 1,500 with APLs, and 150 with APLs with HGD.

Endpoint	Updated SimpleScreen CRC CV study (US Census Weighted Endpoints)		SimpleScreen CRC in PREEMPT CRC study (US Census Weighted Endpoints)
Endpoint	N	Value (95% CI)	N	Value (95% CI)
Sensitivity for CRC (Primary)	89	80.4% (70.2%, 87.7%)	72	81.1% (71.3%, 88.1%)
Sensitivity for APL (Primary)	1570	18.2% (16.3%, 20.4%)	2567	13.7% (12.4%, 15.0%)
Sensitivity for HGD (APL 2.1) (Secondary)	157	41.9% (34.0%, 50.3%)	110	30.5% (22.7%, 39.5%)

Detecting APLs, particularly those with HGD, is important because these lesions are more likely to progress to colorectal cancer if left untreated. The sensitivity results for APL and APL with HGD demonstrated in this study are the highest reported to date for any non-invasive screening blood test in a prospective registrational pivotal clinical study. With the improved detection of APLs and HGD, our published model suggests that the updated test would result in 7.7% more life-years gained, 9.5% more cases of cancer prevented, and 9.5% more cancer deaths prevented, compared to the first-generation CRC test version.
