SKYWEST, INC. ANNOUNCES FOURTH QUARTER 2011 RESULTS

St. George, Utah—SkyWest, Inc. (“SkyWest”) (NASDAQ: SKYW) today reported operating revenues of $899.9 million for the quarter ended December 31, 2011, compared to $796.3 million for the same period last year.  SkyWest also reported a net loss of $(18.0) million, or $0.35 per basic and diluted share, for the quarter ended December 31, 2011, compared to $37.2 million of net income, or $0.67 per diluted share, for the same period last year.

During the quarter ended December 31, 2011, SkyWest experienced a reduction of approximately $79.2 million in pretax earnings (of which $32.8 million relates to items that positively impacted the results for the fourth quarter of 2010) compared to the same period last year.  Additionally $6.8 million of the difference between the comparable quarters is non-operational and is related to SkyWest’s foreign investments. The combination of these items is $39.6 million or approximately 50% of the difference for the comparable quarters.  Following are the significant items that contributed to the pretax reduction:

·                  Recorded $15.6 million gain in the fourth quarter of 2010, attributable to the acquisition of ExpressJet Holdings

·                  Recorded $17.2 million of additional revenue from contract settlement issues in the fourth quarter of 2010

·                  Incurred $15.6 million in additional maintenance costs during the fourth quarter of 2011, primarily related to labor, aircraft paint, parts and airframe heavy check costs

·                  Recorded $15.2 million increase in the pretax loss from ExpressJet operations (acquired in November 2010) for the fourth quarter of 2011

·                  Incurred $8.0 million in additional crew-related costs due to additional staffing needs during the fourth quarter of 2011

·                  Recorded additional $6.8 million loss attributable to SkyWest’s minority investments in Trip Linhas Aereas (“TRIP”) and Mekong Aviation Joint Stock Company (“Air Mekong”)

Commenting on the results, Jerry C. Atkin, Chairman and CEO said, “We experienced some unanticipated expenses in the fourth quarter, however, I remain confident in our ability to respond to these challenges.”  He continued, “We have an action plan in place for 2012 that we have started to execute and is expected to return us to profitability for the year.  Having said that,

we expect the first quarter of 2012, to be challenged but somewhat mitigated from our fourth quarter 2011 results.”

On November 12, 2010, SkyWest completed the acquisition of ExpressJet Holdings, Inc. (“ExpressJet Holdings”) and ExpressJet Holdings became a subsidiary of Atlantic Southeast Airlines, Inc. (“Atlantic Southeast”), a wholly-owned subsidiary of SkyWest.  During the fourth quarter of 2011, the operations conducted by ExpressJet Holdings and its subsidiaries were combined into Atlantic Southeast, and the combined operations are now conducted as ExpressJet Airlines, Inc. (“ExpressJet Airlines”), which is a wholly-owned subsidiary of SkyWest.  The acquisition of ExpressJet Holdings included 244 regional jet aircraft and SkyWest’s consolidated operations and financial results for the quarter ended December 31, 2011 include significant increases related to revenues, expenses and statistical data compared to the quarter ended December 31, 2010.

Financial and Operating Results

SkyWest’s operating revenues increased $103.6 million, or 13.0%, during the quarter ended December 31, 2011, over the same period in 2010.  The increase in operating revenues was largely due to having a full quarter of ExpressJet Holdings’ operations in the fourth quarter of 2011 compared to a partial quarter in 2010 (consisting of the period between the acquisition date, November 12, 2010, and December 31, 2010), which contributed approximately $128.2 million of additional revenues. The increase was offset, in part, by recording approximately $24.5 million in rate settlement and other contractual issues as additional revenue the fourth quarter of 2010.

Total airline expenses (consisting of total operating and interest expenses) increased $158.8 million, or 20.7%, during the quarter ended December 31, 2011, over the same period in 2010.  The increase in total operating and interest expenses was largely due to including the entire quarter of ExpressJet Holdings’ operations in the fourth quarter of 2011 compared to a partial quarter in 2010 (consisting of the period between the acquisition date, November 12, 2010, and December 31, 2010), which generated $141.8 million of additional expenses. SkyWest also experienced cost increases in several cost categories including, crew costs, airframe and engine maintenance costs and pro-rate fuel costs, as previously outlined.

Under United Express agreements for SkyWest Airlines and ExpressJet Airlines, SkyWest recognizes revenue at a fixed hourly rate for mature engine maintenance on regional jet engines and SkyWest recognizes engine maintenance expense on its CRJ200 regional jet engines on an as-incurred basis as maintenance expense.  During the quarter ended December 31, 2011, CRJ200 engine expense under these agreements decreased $1.9 million to $19.3 million compared to $21.2 million for the quarter ended December 31, 2010, as a result of decreased engine overhaul expense due to the timing of scheduled engine maintenance events.  SkyWest was reimbursed approximately $8.9 million and $8.5 million under its United Express agreements in each of the periods ended December 31, 2011 and 2010, respectively.

Liquidity

At December 31, 2011, SkyWest had $646.5 million in cash and marketable securities, compared to $804.9 million as of December 31, 2010. The reduction in cash and marketable securities during the year ended December 31, 2011 was primarily related to paying $60.7 million in

authorized share repurchases and from increases in its prepaid aircraft lease amounts and changes in certain other working capital accounts of approximately $43.5 million.  SkyWest’s long-term debt was $1.61 billion as of December 31, 2011, compared to $1.74 billion as of December 31, 2010.  The decrease in long-term debt was due primarily to SkyWest’s payment of normal recurring debt obligations.  SkyWest has significant long-term lease obligations that are recorded as operating leases and are not reflected as liabilities on SkyWest’s consolidated balance sheets.  At a 5.2% discount rate, the present value of these lease obligations was approximately $2.0 billion as of December 31, 2011.

Other Items

During the quarter ended December 31, 2011, SkyWest also achieved the following milestones:

·                  Added two new CRJ700 regional jets and four used CRJ200 regional jets and removed one CRJ200 regional jet from service

·                  Repurchased 375,084 shares of outstanding common stock at a cost of $4.5 million

·                  Total fleet as of December 31, 2011 consisted of 732 total aircraft compared to 710 aircraft for the same period last year, primarily as a result of the acquisition of ExpressJet Holdings

·                  Completed contractual agreement with US Airways for 14 CRJ200 regional jets and began operations in December 2011with first two aircraft

·                  Achieved Single Operating Carrier (SOC) Certificate November 18, 201, for ExpressJet and Atlantic Southeast
