Further, the average revenue per active earning OPTAVIA Coach improved by +9.7%. Management’s long term goal is to have 30,000 Health Coaches by the end of 2019 which would be a growth level of 50% over the next two years. Due to the strong customer response, management increased Q1 18 revenues and EPS estimates above consensus. Operating profits are now expected to improve by +27% YoY (previous was +19% growth), and sales to gain between +25%-30%. Management also increased FY 18 EPS and sales guidance; EPS is now expected to be between $3.15-3.25 (above consensus estimate of $2.73), and sales are pegged to grow between 16-19% (above consensus of 11%). Management’s Take According to Dan Chard, CEO, “ Our financial results exceeded our expectations and we are pleased to report a strong finish to the year with revenue through our OPTAVIA Coaches model generating record growth.
