FuelCell Energy reported lower-than-expected revenue for 1Q due to a decrease in licensing revenue as well as the temporary closure of fuel cell plants. Shares of the manufacturer of fuel cell technology platforms were down about 9% in the pre-market trading session today. FuelCell Energy’s (FCEL) revenue decreased by 9% year-over-year to $14.88 million, from $16.26 million in the comparable year-ago period, and lagged analysts’ estimates of $22.11 million.
