Lindblad Expeditions shares were up 15 percent at market open on Monday, August 3 as the company reported second quarter earnings and the best second quarter occupancy in 10 years at 91 percent. Occupancy climbed to 91 percent from 86 percent a year earlier, the highest second quarter rate in a decade and the second consecutive quarter the company topped its 90 percent target. Leahy said the gain came alongside a 12 percent increase in capacity, with the company driving both occupancy and yield despite the added berths. Net yield per available guest night rose 4 percent to $1,294, a second quarter record and the sixth straight quarter of record net yields. It lifted net yield guidance to between 4.5 and 5.5 percent while maintaining adjusted EBITDA guidance of $130 million to $140 million.
