SkyWest, Inc. Announces Third Quarter 2015 Results

St. George, Utah—SkyWest, Inc. (“SkyWest”) (NASDAQ: SKYW) today reported financial and operating results for the quarter ended September 30, 2015.

SkyWest generated $36 million of net income for Q3 2015, or $0.71 per diluted share.  Excluding special items, SkyWest’s net income for Q3 2014 was approximately $26 million, or $0.50 per diluted share.

Operating income for Q3 2015 was $78 million, an increase of 32% from Q3 2014 of $59 million.

SkyWest reported $77 million of net income for the nine months ended September 30, 2015, or $1.49 per diluted share, a $88 million improvement from the corresponding period of 2014, which had net loss of $11 million, excluding 2014 special items.

Commenting on the results, Chip Childs, SkyWest, Inc. President said, “Our third quarter results reflect continued progress in the optimization of our fleet and flying contract mix.  These improvements, along with solid operating performance, have contributed to our increasing operating margins. Additionally, we look forward to operating the E175 aircraft with three of our major partners by mid-2016, and we believe our operating performance continues to create additional opportunities to improve our fleet mix and operating margins.”

Q3 2015 Financial Highlights

·                  Operating margin increased to 9.9% in Q3 2015 compared to 7.1% in Q3 2014.  The improvement in operating income and operating margin was primarily due to additional flying contracts with improved profitability, improved operating performance and a reduction in the number of aircraft operating under unprofitable or less profitable flying contracts.

·                  SkyWest generated $145 million in cash from operations in Q3 2015, compared to $129 million in Q3 2014, excluding special items in 2014.  For the nine months of 2015, cash from operations was $314 million, compared to $161 million for the nine months of 2014, excluding special items in 2014.

·                  Q3 2015 revenue included the benefit of $31 million from additional Embraer dual-class jet aircraft (“E175”) operations, improved contract rates from renewals of SkyWest’s existing flying contracts, improved contract performance incentives, and $4 million from higher flight completion rates compared to Q3 2014.  These improvements provided a significant offset to the revenue

decrease from a reduced fleet size and lower scheduled production levels from Q3 2014.  Total revenue of $794 million for Q3 2015 decreased $41 million from Q3 2014.

·                  Operating expenses were down by $60 million, or 7.7%, compared to Q3 2014, primarily driven by operating efficiencies from improved completion rates, a net decrease in production, maintenance cost initiatives and a reduction in fuel costs.

Reconciliation of Non-GAAP financial measures

Although SkyWest’s financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”), SkyWest management believes that certain non-GAAP financial measures may provide investors with useful information regarding the underlying business trends and performance of SkyWest’s ongoing operations and may be useful for period-over-period comparisons of such operations.  The following table sets forth supplemental financial data and corresponding reconciliations to GAAP financial statements for the three and nine-month periods ended September 30, 2015 and 2014 (dollars in millions).  Readers should consider these non-GAAP measures in addition to, not a substitute for, financial reporting measures prepared in accordance with GAAP.  These non-GAAP financial measures exclude some, but not all, items that may affect SkyWest’s net income.  Additionally, these calculations may not be comparable with similarly titled measures of other companies.

The special item in Q3-2014 was a pre-tax gain of $24.9 million from the sale of SkyWest’s 20% equity interest in TRIP Linhas Aereas (“TRIP”), reflected as other income in the accompanying statements of income.
