SKYWEST INC (SKYW) stock intrinsic value fair value estimate & owner earnings analysis

SkyWest is the largest regional airline in the United States. It flies regional jets of up to 76 seats (Embraer E175s and Bombardier CRJs) for four major airlines under capacity purchase agreements. At the end of 2025, 216 of its 487 contracted aircraft flew for United, 137 for Delta, 92 for American and 42 for Alaska. About 84% of 2025 flying revenue came from these fixed-fee agreements, under which the partner airline pays for fuel and compensates SkyWest for the cost of owning the aircraft; the rest is route-share (prorate) flying and charter. SkyWest generally buys and finances its aircraft itself, mostly with debt, and also leases aircraft and engines to third parties. The four airlines are, in effect, the whole customer base and they set the rates. Contracts end aircraft by aircraft; the latest scheduled termination dates are 2033 for United, 2034 for Delta, 2032 for American and 2034 for Alaska. In January 2026 the contract dates on 40 United E175s and 13 Delta E175s were extended. Signed placements already include eight new E175s with United and one with Alaska in 2026, 16 new E175s with Delta (ten in 2027, six in 2028) and 23 used CRJ550s with United by the end of 2026, which SkyWest is converting from CRJ700s it already owns. Earnings follow pilot availability and contract rates rather than fuel or ticket prices. In 2022 and 2023 a shortage of captains kept SkyWest from flying its full schedules: operating income was $181 million in 2022 (after a $51 million write-down of aircraft held for sale) and $104 million in 2023. By the end of 2025 it was flying full schedules again, with completed departures up from about 692,000 in 2023 to about 864,000 in 2025, and operating income reached $618 million on $4.06 billion of revenue. In the first half of 2026 revenue rose 6.7% to $2.12 billion, but operating income fell 9.7% to $280 million because labor expense grew 10.6%. How we measured the business. For each year we took what the business produces for all of its financiers: operating cash flow, less working-capital swings, less stock compensation, less the aircraft spending needed to keep the fleet going, then added back cash interest, and finally subtracted what is owed to lenders. Judgements that matter: working-capital swings were removed (2023 included a $313 million inflow, of which $230 million was an increase in deferred revenue that we could not trace to a specific contract, and 2024 included a $125 million outflow); deposits on aircraft on order were counted as capital spending; spending to grow the fleet was separated from replacement spending using SkyWest's own ten-year ratio of capital spending to revenue (about 21%); federal payroll support grants of $345.5 million in 2020 and $422.7 million in 2021 distort those years, so they are excluded; and the January 2019 sale of ExpressJet changed the business, so earlier years are not used. Cash taxes have run well below book taxes because of accelerated depreciation on aircraft (deferred taxes added $123 million to 2025 operating cash flow). We left that in, but it would reverse if aircraft purchases stopped. Normal level. On this basis, cash earnings before interest were $256 million in 2019, $162 million in 2022, $230 million in 2023, $710 million in 2024 and $482 million in 2025. We use the median of those five years, $256 million a year (about $6.46 per share on today's 39.6 million diluted shares). That window includes a pre-pandemic year, the captain shortage, the recovery, and both light and heavy years of aircraft buying. Cash earnings fell 32% in 2025, driven by aircraft spending that doubled from $328 million to $653 million (including seven new E175s); before aircraft spending they rose 12%, and cash from operations in the first half of 2026 was $436 million against $428 million a year earlier. We therefore start at the normal level with no growth, which is 47% below 2025. Base case. The $256 million continues unchanged through 2040 and then winds down evenly to zero by 2050. We credit no growth: the January 2026 extensions and the conversion of owned CRJ700s for United show aircraft being kept in service, but nothing in the filings secures more flying than today's. We left out the 44 E175 delivery positions for 2028 to 2032 that have no airline contract yet, margin gains, share gains, and any value after 2050. The business is worth about $2.88 billion. SkyWest owes about $1.91 billion net: $2.30 billion of debt at June 30, 2026, less $301 million of cash and securities above the roughly $300 million (about a month of operating costs) needed to run the airline, less about $90 million because the debt costs an average of only 4.4%. The difference is about $0.97 billion, or $24.54 a share. Bear case. A shutdown like 2020 arrives in 2027 and 2028. Without government grants, cash earnings in 2020 and 2021 would have been roughly negative $147 million and negative $156 million, so we use negative $150 million for two years (against about $100 million of annual interest), then $100 million in 2029. After that earnings settle at $196 million a year, the average of the two captain-shortage years and about a quarter below the normal level, which is also roughly what losing a quarter of today's flying as contracts end would cost; this lasts through 2040 and then winds down to zero by 2050. We give no credit for the low cost of the existing debt and instead add about $90 million for refinancing in a downturn. The business is worth about $1.59 billion, SkyWest owes about $2.09 billion net, and it owes roughly $0.5 billion more than the business is worth, or negative $12.62 a share: shareholders would receive nothing and could be diluted by new shares or forced asset sales along the way. Two years of losses plus interest would use roughly $500 million of the $601 million of cash and securities while $550 million (2026) and $506 million (2027) of scheduled debt principal comes due. Bull case. The $482 million earned in 2025, with full schedules, continues unchanged through 2045 (partners keep extending contracts as in January 2026, and E175 deliveries are scheduled to 2032), then winds down to zero by 2055. The business is worth about $6.08 billion against $1.91 billion owed, leaving about $4.17 billion, or $105.35 a share. First-half 2026 operating income is running 10% below 2025, so this case needs that level to be recovered or held. Commitments and what we tested. SkyWest has firm commitments for 69 new E175s through 2032, $2.28 billion of aircraft and spare-engine purchases ($278 million in 2026 and $323 million in 2027), which it plans to finance 75% to 85% with debt. Twenty-five of these have airline contracts; 44 do not. We treat the purchases as replacement spending already inside the normal level and credit no earnings to the unplaced aircraft. We tested the normal level and the duration. If cash earnings run 14% below normal ($220 million), the base value falls to about $14 a share; if they stay at the 2022-23 average of $196 million, about $7.52; and if the normal level lasts only through 2034 and then winds down over ten years, about $9.87. The aircraft purchase prices and the economics of the partner contracts are redacted in the filed exhibits, so we could not test the returns on new aircraft. Our earlier published estimate was prepared on a different basis and is not comparable. Why the margin-of-safety price is $14. We are only moderately sure of the earnings level: it is a median across years ranging from $162 million to $710 million. The worst plausible outcomes are another pilot shortage or a 2020-style shutdown while SkyWest owes about $1.9 billion net, has $2.28 billion of aircraft commitments and depends on four customers. The aircraft-backed debt and $601 million of liquidity would survive a repeat of 2022-23, but a shutdown without grants could force expensive refinancing or new shares and wipe out shareholders, as in the bear case. SkyWest has no dividend we can count on (the filing gives no assurance one will resume); at the normal level it generates about $155 million a year after interest (about $3.90 a share), which can go to repay debt and repurchase stock ($213 million of authorization remained at the end of 2025). The price assumes a three-to-five-year holding period. At $14 that cash is a yield of about 28% a year; the price still implies about 20% a year if cash earnings run 14% below normal for fifteen years with nothing after 2040, and about 15% if they stay at the 2022-23 average. At a higher price, even a modest disappointment no longer implies 20%, while the bear case leaves shareholders with nothing.
