Trainer becoming a distraction, but core business solid

AIRLINES Sector Weighting Market Overweight DELTA AIR LINES, INC. (DAL $20.80 Outperform) Trainer becoming a distraction, but core business solid Clean beat with EPS of $0.98 above our estimate of $0.93 mostly on non-fuel cost savings that, importantly, don t appear to be one-time in nature. More importantly, DAL grew EBIT margins y/y and guided to another quarter of y/y EBIT margin growth in 3Q. We believe investors including ultra-short term ones are more willing to accept the premise of margin expansion carrying more weight than second derivative PRASM changes (though PRASM guidance for July/Aug was good, too). Margin guidance. DAL has now come within around ~100bp of its initial margin guidance in each of the last six quarters. DAL s earnings are by far the most stable of the network airlines we cover, which we believe will help attract the incremental investor to the sector and more specifically, DAL s stock. DAL s 3Q EBIT margin guide of +11% to +13% was above our estimate by about 100bp. Trainer becoming a distraction. RIN-related issues exacerbated refinery losses, causing Trainer to lose $51M in the quarter and bringing the trailing 3Q loss there to $136M. This was an area of focus on the analyst call. There is no doubt that Trainer s jet fuel output has contributed somewhat to lower east coast jet fuel prices via higher overall domestic supply, but it s hard to quantify that benefit (which is shared by DAL s competitors, of course). Trainer might work out in the long run for DAL, but in the near term it seems to be stealing thunder from what is an otherwise compelling execution story at the core airline business. As of now, we do not view Trainer risk as a reason to avoid shares of DAL. Demand trends solid. DAL expects July/Aug PRASM growth of ~3% y/y, which was ~150bp above our expectations. That, combined with a good trajectory of nonfuel CASM means our estimates move up, as does our target price. Raising estimates and target price to $25. We affirm DAL as our top idea in airlines, a space we rate as Market Overweight, because of DAL s cash flow. DAL isn t perfect (who is?), but upside catalysts far outweigh risks, in our opinion, and the equity markets still don t seem to be extending DAL the benefit of the doubt on fiveyear cash generation potential. Our target price is based on merely 7x our higher 2014 cash EPS estimate (see estimate changes in table below).

Investment Conclusion DAL closed up 2% following its 2Q earnings and earnings call, versus our WR Airline Index (ex-dal) up less than 1% and the S&P 500 down slightly. DAL is now up 75% YTD, versus our WR Airline Index (ex- DAL) up 36% and the S&P 500 up 18%. On our upwardly revised estimates DAL is trading at 6.5x rolling twelve month forward EPS versus its one and five year averages of 5.0x and 6.3x, while trading at 5.2x rolling twelve month forward EV/EBITDAR versus its one and five year averages of 4.6x and 5.1x. Key takeaways from the report and the conference call Three positive surprises: 1. July & August PRASM guidance of +3% y/y was about 150bp better than we expected it would be 2. The CASM ex-fuel beat didn t appear to be timing driven and should accelerate into 2H13 3. Fuel guidance of $3.05 to $3.10/gal was much lower than we thought, especially when factoring in what should be another tough quarter for the Trainer refinery due to RINs and core refining losses (though we are struggling to reconcile this guidance with the spot price of jet fuel, DAL s hedge book, Trainer, and other jet fuel-related expenses like taxes, etc.) Three negative surprises: 1. Higher interest rates don t appear to be having a material impact on pension savings for DAL s P&L 2. Trainer is becoming more and more complicated and hard for general investors to follow/model 3. Lots of talk of corporate market share gains for an industry that has supposedly moved past market share battles Conclusion: Today s earnings call was positive. Trainer may or may not work out for DAL in the long run, but we ll be the last analysts to play Monday morning quarterback on this issue. DAL took a risk with the Trainer acquisition, and that risk was taken with the intention of creating shareholder value (as opposed to, say, making customers happy). For now, the strategy isn t working. DAL s estimate of $300M of annual fuel savings likely won t happen, at least this year, and as the refinery losses accumulate it is distracting from what is otherwise a strong transformational story. In the meantime, DAL s network is functioning strongly and cash generation is robust. Guidance for near-term demand trends exceeded even the most bullish of estimates, in our opinion, and consensus estimates likely have room to expand. We are optimistic about the near and long term prospects for shares of DAL, and our new target price of $25 is based on 7x our higher 2014 cash EPS estimate. Longer term we can see this multiple expanding to 10x cash EPS estimates when DAL s margins are sustainably in the low double digits, as we expect will occur. We reiterate our Outperform rating on shares of DAL. More below. WolfeResearch.com Page 2 of 6
