INVESTOR ACTION NOTICE: Moore Law PLLC Encourages Investors in Fractyl Health, Inc. to Contact Law Firm

NEW YORK, Oct. 19, 2026 /PRNewswire/ --

What is the Investigation About?

On January 29, 2026, before the market opened, Fractyl Health, Inc. announced six-month data from its REMAIN-1 Midpoint Cohort evaluating Revita for weight maintenance after discontinuation of GLP-1 therapy. Revita-treated patients experienced 4.5% weight regain, compared with 7.5% in the sham-treatment group. The Company also stated that the cohort was not designed to be sufficiently powered for efficacy analysis. During an investor call that same day, management disclosed that one study site had higher-than-expected weight regain across both treatment groups and materially contributed to the results.

Following this news, the price of Fractyl stock fell $1.245 per share, or 68.03%, to close at $0.585 per share on January 29, 2026.

After the market closed that day, Canaccord Genuity reported that management attributed the variability at one site to a less robust diet and lifestyle counseling program. Morgan Stanley also downgraded Fractyl and reduced its price target from $8.00 to $2.00. The next day, Fractyl stock fell another $0.125 per share, or 21.37%, to close at $0.46 per share on January 30, 2026.
