SKYWEST, INC. ANNOUNCES FOURTH QUARTER 2014 RESULTS

St. George, Utah—SkyWest, Inc. (“SkyWest”) (NASDAQ: SKYW) today reported financial and operating results for the quarter ended December 31, 2014.  Highlights are as follows:

Excluding special items, SkyWest’s pre-tax income was $33.5 million for the December 2014 quarter, an increase of $18.4 million over the December 2013 quarter.  SkyWest’s net loss, including special items, was $(27.9) million, or $(0.54) per diluted share, for the December 2014 quarter, compared to net income of $8.6 million, or $0.17 per diluted share, for the December 2013 quarter.

The December 2014 quarter includes special item expenses of $70.0 million pre-tax ($43.6 million after-tax) due to the accelerated retirement of SkyWest’s EMB-120 turboprop aircraft and a code-share agreement modification that shortened the contract term for ExpressJet’s operation of the ERJ145 aircraft type.

SkyWest’s pre-tax income for the December 2014 quarter, excluding special items, increased 122% from the December 2013 quarter, despite a 6.6% reduction in departures and a 4.4% reduction in completed block hours, from the December 2013 quarter.  Excluding the special items, the increase in pre-tax income from the December 2013 quarter was primarily due to higher unit revenue from new and renewed flying arrangements at improved rates as described in more detail below.

For the 2014 year, SkyWest’s pre-tax income, excluding special items, was $58.4 million, compared to $98.5 million for the 2013 year.  SkyWest’s net loss, including special items, was $(24.2) million, or $(0.47) per diluted share, for the 2014 year, compared to net income of $59.0 million, or $1.12 per diluted share, for the 2013 year.

·                  Significant operational and commercial items related to the December 2014 quarter include:

·                  SkyWest Airlines took delivery of six E175 aircraft during the quarter under its flying contract with United, which resulted in a total of 20 E175 deliveries for calendar 2014.  SkyWest is scheduled to take delivery of the remaining 20 E175s under its United agreement during the first three quarters of 2015.

·                  SkyWest Airlines reached an agreement with Alaska to operate seven new E175 aircraft with deliveries scheduled between the third quarter of 2015 and the first quarter of 2016.

·                  SkyWest Airlines reached an agreement with Delta to operate 12 additional used CRJ200

aircraft that SkyWest Airlines intends to lease from Delta.  The aircraft deliveries started in December 2014 and are scheduled to continue through the second quarter of 2015.

·                  SkyWest Airlines started the removal of 43 EMB-120 turboprop aircraft from service and is expected to be an all-jet operator by the conclusion of the second quarter of 2015.  As of December 31, 2014, SkyWest owned 18 EMB-120s and leased 25 EMB-120s.

·                  For the second consecutive quarter, ExpressJet’s operational reliability improved year-over-year to a 99.6% adjusted completion rate for the December 2014 quarter compared to 99.1% for the December 2013 quarter.

·                  ExpressJet reached an agreement with American to operate 15 used ERJ145 aircraft that ExpressJet intends to lease from American.  The American ERJ145 operation is scheduled to begin during the first quarter of 2015.

·                  ExpressJet removed 10 ERJ145s from its United flying contract during the fourth quarter of 2014 and is returning the aircraft to United.  ExpressJet removed a total of 26 ERJ145s from its United flying contract during the 2014 year.  Additionally, 59 ERJ145s and nine ERJ135s are scheduled to be removed from service during 2015 and to be returned to United.  As of December 31, 2014, ExpressJet had 216 ERJ145s and nine ERJ135s operating under the United ERJ contract.

Commenting on the results, Jerry C. Atkin, SkyWest’s Chairman and CEO said, “SkyWest made significant progress in executing our long-term strategy in the fourth quarter, including reducing the total number of unprofitable aircraft and flying over time.  We expect these changes to continue through 2017, as we continue to work with our major airline partners to meet their needs with larger RJ opportunities during that same period.  We expect that reducing our total fleet count while improving the overall fleet composition will put us on a path of continued financial and operational improvement.”

·                  Other financial items related to the December 2014 quarter include:

·                  Total operating revenues, excluding the direct reimbursements for items such as fuel, landing fees, station rents, and engine maintenance received under the flying contracts, increased by approximately $19 million during the December 2014 quarter from the December 2013 quarter.  The improvement was primarily due to the new E175 aircraft operations, improvements in certain contract renewals, increased government subsidies for operating certain routes and financial incentives for operating performance under our flying contracts.

·                  Special item expenses (reflected in operating expenses) during the quarter included $70 million (pre-tax) associated with the accelerated removal of the EMB-120 aircraft and anticipated reduction in the future use of the ERJ145 aircraft, of which approximately $60 million consisted of non-cash write down of asset values and approximately $10 million consisted of obligations resulting from the accelerated removal of leased aircraft from service.

·                  Total operating expenses, after excluding expenses subject to direct reimbursement under the contract flying arrangements and special items, remained essentially constant during the December 2014 quarter from the December 2013 quarter.

·                  Capital and liquidity items related to the 2014 year include:

·                  SkyWest had $559 million in cash and marketable securities at December 31, 2014.  Cash and marketable securities decreased $111 million during 2014 primarily due to SkyWest’s investment of $82 million towards the E175 ownership and $42 million to acquire E175 spare parts, engines and tooling.

·                  Long-term debt increased $275 million from December 31, 2013 to December 31, 2014.  The increase was primarily due to the issuance of $454 million of long-term debt for the 20 E175 aircraft delivered in 2014, partially offset by principal payments made on total outstanding debt.
