LAS VEGAS. April 24, 2013 -Allegiant Travel Company (NASDAQ: ALGT) today reported the following financial results for the first quarter 2013, as well as comparisons to prior year equivalents.

“We are very proud to report our 41st consecutive profitable quarter,” stated Maurice J. Gallagher, Jr., Chairman and CEO of Allegiant Travel Company. “The month of March is typically our busiest month of the year, and this year was no different. Thanks to the tireless efforts of our Team Members, we have had another profitable quarter.”

Notable company quarterly highlights

Began flying our first A319 on March 1, 2013, the second A319 on April 4, 2013

Repurchased over 284,000 shares for $22.2 million dollars, average purchase price of $78.15

Received board approval to increase share repurchase authority to $100 million

Completed the 166 seat MD-80 conversion project in February

Added two new small cities Provo, UT and Reno, NV

Added eight routes in the quarter

Announced five routes which will start in the second quarter, including one new city, Little Rock, AR

Operated 198 routes in the first quarter of 2013. Expect to operate 203 routes in the second quarter of 2013

First quarter 2013 revenue performance

13th consecutive quarter of year over year increases in total average fare

First quarter 2013 average fare, average ancillary air per passenger, and total fare were the highest in the company’s history

First quarter TRASM increased by 1.2 percent even though we increased average scheduled service stage length by 4.9 percent and scheduled service ASMs grew by 17 percent

Load factor returned to a normalized rate closer to 90%

Same store markets, those which were operated in the first quarter 2012 and 2013, had a 4.3 percent TRASM increase versus the system average of 1.2 percent

Fixed fee revenue’s decline is attributable to no longer operating two aircraft in track charter programs as previously disclosed

First quarter 2013 cost performance

Operating CASM, excluding fuel increased only 0.2 percent to 5.18 cents despite an almost eight percent decrease in aircraft utilization for the same time period due to a higher concentration of flying during peak periods

Operating expense per ASM decreased by three percent even though our average fuel expense per gallon increased by three percent. System ASMs per gallon of fuel improved to 67.3; a 9.6 percent increase versus the first quarter 2012

Maintenance and repairs expense per passenger decreased by 19.2 percent due to a more normalized rate of engine overhaul expense compared to unusually high levels in the first quarter of 2012

Salary and benefits expense per passenger increased by 18.4 percent due mainly to increases in pilot compensation. As we reached a trailing twelve month operating margin of 14 percent in November of 2012, our pilots moved into a higher pilot pay rate band per our compensation agreement with our pilot work group. Additionally, higher flight attendant headcount resulting from the increased gauge of our MD-80 aircraft and operating six 757 aircraft as opposed to one during the first quarter 2012

Depreciation and amortization per passenger increased 35 percent primarily due to accelerated depreciation from the announced retirement of six MD-80s from first quarter 2013 through third quarter 2013, along with higher depreciation stemming from 51 converted 166 seat MD-80s at the end of the quarter versus 17 a year ago

Other expense per passenger increased 35 percent primarily attributable to a higher write-down of engine values in our consignment program

Second quarter 2013 cost trends

Salary and benefit expense is still subject to the same pressures as in the first quarter including the higher pilot pay band in effect

We expect the bulk of the engine and heavy airframe maintenance for the year will be incurred in the second and third quarters. For the full year, we are still anticipating maintenance per aircraft per month to be between $100 thousand and $110 thousand which has been our normalized historical run rate

Second quarter depreciation expense will still feel the impact of the accelerated depreciation reflected in the first quarter and to a lesser extent the higher depreciation from the converted 166 seat MD-80s as we had converted 27 aircraft by the end of June 2012. Four of the MD-80s driving the bulk of the accelerated depreciation are scheduled to be retired in the third quarter of 2013. In addition, we are expecting higher depreciation in the fourth quarter as we are currently expecting to place seven A320s into service by the fourth quarter of 2013

Third party products performance

Ancillary revenue third party products per passenger has seen year over year growth for 12 consecutive quarters

First quarter departures to Las Vegas decreased over 17 percent versus last year, while growth in Florida departures increased ten percent year over year. These changes drove our corresponding decrease in hotel room nights (Las Vegas is our largest hotel market) and increase in car rental days (Florida is our strongest rental car market in our system)
