Delta Air Lines, Inc.

DAL

FAVORABLE

May 27, 2026

Research Conclusion

BUY — Moderate-High Conviction. Delta is a Premium Airline + Loyalty Compounder, with the AmEx remuneration agreement ($8.5B FY2025 → $10.3B FY2028) representing ~14% of revenue at near-100% margin. At ~$70 vs. PWFV $85-90, upside +21-29%. The variant frame: market values DAL as cyclical airline (10x P/E); reality is loyalty compounder with contractually protected AmEx flywheel through 2035 — deserving 12-13x. Berkshire's re-entry (6.1% stake, $2.6B) validates the variant. Bull case +66%; bear (credit card cap) -29-43%. Position 2-4%.

Company Overview & Moat Assessment

Delta Air Lines (NYSE: DAL) is a premium global airline with the highest PRASM among Big 3 US carriers (17.65 vs. UAL 16.66). The unique strategic asset is the AmEx co-brand partnership (contracted through 2035) generating $8.5B in remuneration (FY2025, ~14% of revenue at near-100% margin). FY2025: revenue $61.5B, op income $6.0B, adj. EPS $5.25, FCF $3B. Net debt $16B / 2.0x EBITDA. Ed Bastian is CEO (since 2016); Erik Snell new CFO (March 2026); Berkshire Hathaway re-entered with 6.1% stake (~$2.6B).

▲ Bull Case

  • ◆AmEx grows to $10B+ + variant multiple expansion: EPS $9 FY2027; multiple 13x → $117 (+66%)
  • ◆Credit card cap legislation fails + management transition smooth: Multiple expansion to 12-13x; FY2027 EPS $7.50 → $90+
  • ◆Buyback re-initiation in FY2027: Debt drops to $11B; ~$3B annual buyback; 4-5% annual share reduction → +15-25%

▼ Bear Case

  • ◆Credit card cap passes: AmEx falls to $6-7B; EPS $5; multiple 10x → $50 (-29%)
  • ◆Recession + fuel spike: EPS $4.50; multiple 9x → $40 (-43%)
  • ◆Management transition disrupts revenue management: Multiple compression on uncertainty → -7-14%
Primary Debate on Wall Street

“Bulls: AmEx flywheel + premium pricing + Berkshire re-entry = compounder; SOTP unlocks 30-40%+. Bears: airline cyclicality + credit card cap + management transition = cyclical re-rating risk. Decision-margin: does AmEx remuneration get capped by federal legislation. The 25% probability bull case generates +66%; the 20% bear case is -29%. R/R asymmetric.”

Top Catalysts
  • ◆Q2 2026 EPS + guidance (July 2026): HIGH impact if AmEx >$2.1B/qtr and EPS >$1.25
  • ◆Credit card rate cap legislation outcome: EXTREME impact if passed
  • ◆Berkshire Hathaway 13F quarterly disclosures: MEDIUM impact if stake maintained
  • ◆FY2026 actual EPS (reported Feb 2027): HIGH impact if >$6.50
  • ◆Snell CFO investor day (TBD 2026): MEDIUM-HIGH impact if AmEx continuity confirmed
  • ◆Buyback initiation authorization (FY2027): HIGH impact
  • ◆Boeing 787-10 deliveries (2031+): LOW-MEDIUM impact if on schedule
  • ◆Premium revenue mix quarterly trend: MEDIUM impact if growing
Top Risks
  • ◆Credit card rate cap legislation (15-20% probability): EXTREME severity — direct AmEx impairment
  • ◆Recession (20% probability): HIGH severity — demand and EPS destruction
  • ◆Fuel spike Brent $100+ (20% probability): HIGH severity — margin compression
  • ◆Bastian early departure (10% probability): MEDIUM severity — strategic uncertainty
  • ◆AmEx 2035 renewal pressure (30% probability): MEDIUM severity
  • ◆Multiple compression (25% probability): MEDIUM severity
  • ◆Boeing delivery delays (30% probability): LOW-MEDIUM severity
  • ◆Berkshire exit (25% probability): MEDIUM severity — negative sentiment signal
