Positive Topline Phase 3 Results Across All Doses Studied For All Co - Primary Endpoints 9 Once - Nightly FT218 at 9 g demonstrated a high degree of statistical significance, compared to placebo, for each of the three co - primary endpoints: • Maintenance of Wakefulness Test (MWT) (p<0.001) • Clinical Global Impression - Improvement (CGI - I) (p<0.001) • Mean weekly reduction in cataplexy attacks (p<0.001) FT218 7.5 g and 6 g also demonstrated statistical significance for the three co - primary endpoints, compared to placebo FT218 was generally well - tolerated; commonly known sodium oxybate adverse reactions occurred at low rates at the highest dose (9 g)

REST - ON Phase 3 Study – Key Inclusion and Exclusion Criteria • Age: 16 and over • Documented diagnosis of narcolepsy (NT1 or NT2) as defined by the International Classification of Sleep Disorders - 3 criteria • Epworth Sleepiness Score (ESS): >10 • May be on stimulants, as long as stable for three weeks prior to entry • Prior to randomization − Maintenance of Wakefulness Test (MWT): < 11 minutes − A mean of at least 8 cataplexy attacks per week during the Baseline Period 11 Key Inclusion Criteria Key Exclusion Criteria • Prior use of sodium oxybate - In 2018, protocol amended to allow prior use of sodium oxybate of 4.5 g or less, for less than 2 weeks and at least 1 year prior to study entry • Current use of sodium oxybate • Must be tapered off any medications for the treatment of cataplexy – SSRIs, SNRIs, TCAs, MAO inhibitors

REST - ON Study – Three Co - Primary Endpoints and Statistical Analysis Plan Change from baseline to endpoint for FT218 compared to placebo at 9 g for: 1. Maintenance of Wakefulness Test 2. Clinical Global Impression - Improvement (% of patients “much” or “very much” improved) 3. Mean weekly cataplexy attacks If 9 g dose was positive, then each of the three endpoints will be assessed at the 7.5 g dose level in the same hierarchical manner If 7.5 g dose was positive, then each of the three endpoints will be assessed at the 6 g dose level in the same hierarchical manner 12
