"I’m happy to report we had our 64th consecutive profitable quarter," stated Maurice J. Gallagher, Jr., chairman and CEO of Allegiant Travel Company. "The past 18 to 24 months have been challenging as we pushed through a successful onetime changeover to an all Airbus fleet. This was a major undertaking by our team. During this period we sustained a number of one-time transition costs but still maintained among industry leading operating margins on our airline activity of 15.3 percent despite a 27 percent increase in the cost per gallon of fuel in 2018.

"And these returns were accomplished despite the added challenges of our fleet transition years. I couldn’t be more pleased with where we find ourselves today as we look forward to 2019 and beyond. We are also pleased with our EPS-based reporting approach which we started in 2018. You will see our estimates for 2019 below.

"Finally, my hat is off to our team. They not only rose up to the logistical challenge of the fleet changeover during the past 18 months, but at the same time continued to elevate our operational performance and customer service standards across the board."

Non-GAAP Presentation

Airline-only operating income excluding write down, airline-only revenue and airline-only operating margin excluding write down all eliminate non-airline revenue and expenses, and the effect of the non-cash impairment charge for the accelerated retirement of the MD-80 fleet in 2017, which are not reflective of our principal operating performance. As such, all of these are non-GAAP financial measures.

The SEC has adopted rules (Regulation G) regulating the use of non-GAAP financial measures. Because of our use of non-GAAP financial measures in this press release to supplement our consolidated financial statements presented on a GAAP basis, Regulation G requires us to include in this press release a presentation of the most directly comparable GAAP measure, which is operating income and total revenue. Our utilization of non-GAAP measurements is not meant to be considered in isolation or as a substitute for operating income or other measures of financial performance prepared in accordance with GAAP. Neither operating income, total revenue, or operating margin less non-airline items and write down are GAAP measurements, and our use of these measures may not be comparable to similarly titled measures employed by other companies in the airline and travel industry.
