Madison Air Solutions Corporation (MAIR) Q2 2026 — Reported the MORNING of July 30 (quarter ended June 30, 2026). Net sales $991.3M (+21.0% GAAP, +14% pro forma, +14.1% organic), adjusted EBITDA $265.8M at a 26.8% margin (DOWN from 27.5%), GAAP EPS $0.15 vs $0.31 adjusted, backlog $2,868.4M (+133.0%). FY26 sales guidance RAISED $75M to $3,825-3,925M while adjusted EBITDA guidance was REAFFIRMED unchanged at $1,020-1,065M. The stock closed down 7.9% at $29.14 (low $28.69 intraday, the widely-quoted -9.3%), then $29.06 on July 31 — the lowest close of its public life. Four numbers in circulation are wrong. The $0.31 EPS is ADJUSTED, not GAAP ($0.15), and the '$0.00 prior year' is a carve-out artifact (it was $0.07). 'Resilient residential' is false: Residential ORGANIC sales FELL 4.8%. And tariffs were a Q2 TAILWIND, not a headwind — the Supreme Court voided them in February and MAIR booked refunds as a reduction to cost of goods sold. THE CALL: HOLD (3/5, A FAIR PRICE FOR A REAL BUSINESS WITH A MARGIN QUESTION) — base-case value ~$31.0 vs ~$29.06 today. KEY METRICS: - CALL: HOLD 3/5 — fair value $31 vs $29.06 (+6.7%). STREET: Buy, 5 buy / 0 hold / 0 sell, but only ~5 firms cover it. Average target $44.63, median $45. Stifel CUT to $41 from $49 on 7/31 (the only post-print revision), RBC $47 (cut from $50), Wells Fargo $46 (cut from $47). We DIFFER: their $44.63 implies 24.2x EV/EBITDA — a Trane multiple. - THE REAL STORY: sales guidance RAISED $75M at the midpoint to $3,825-3,925M, adjusted EBITDA guidance REAFFIRMED unchanged at $1,020-1,065M. That is an implied FY margin cut from 27.43% to 26.90%, 53bps. More revenue at zero incremental profit. The market read it correctly. - COMMERCIAL INCREMENTAL MARGIN 13.5%: Commercial sales +$126.5M (+23.8%, 22.3% organic) but Commercial adjusted EBITDA only +$17.3M. Segment margin fell from 29.3% to 26.3%, down 303bps. Management: the comparison 'primarily reflects rapid growth in large data center programs, project mix, capacity addition investments and program ramp costs'. The record backlog and the lost margin are the SAME event. - RESIDENTIAL IS NOT RESILIENT: reported +16.2% but ORGANIC sales FELL 4.8% (-3.4% for the half). AprilAire contributed $56.4M against a $46.5M total increase. Residential backlog FELL from $71.5M to $66.0M. Its margin rose 423bps to 29.5% — but $21.8M of the $25.9M EBITDA gain was AprilAire, plus 'favorable net tariff impacts'. - TARIFFS WERE A TAILWIND: the Supreme Court invalidated certain emergency-authority tariffs in Feb 2026; MAIR began receiving REFUNDS in Q2 and booked them as a reduction to cost of goods sold. Adjusted gross margin STILL fell 120bps to 39.0%. Underlying margin is worse than printed, and the help does not repeat. - THE Q4 BET: guidance implies H2 margin of 27.72% vs 26.07% delivered in H1. Management guided Q3 'roughly flat'. Hold Q3 at Q2's 26.8% and Q4 must print ~28.6% — the highest margin ever disclosed, 180bps above the quarter just reported. - SHARE COUNT + STRUCTURE: 10-Q cover 7/28/26 — Class A 177,342,753 + Class B 324,379,859 = 501,722,612 shares, both fully economic (Class B is 10 votes, not a stub). Market cap $14.58B, net debt $2,791.9M ($3,053.7M debt less $261.8M cash), EV $17.37B = 16.7x FY26E EBITDA. Holdings (founder Larry Gies) has 64.7% of economics and 95.2% of votes. - UNUSUALLY CLEAN FOR A SPONSOR IPO: NO Tax Receivable Agreement at all. And the control block is NOT a 180-day cliff — the prospectus discloses TWO-YEAR lock-ups with Holdings and Kedge running to ~April 2028. Backlog $2,868.4M (+133.0%), book-to-bill 1.34x (1.51x Commercial), net leverage 2.8x after repaying $2,625.7M with IPO proceeds. - VALUATION: 2027E sales ~$4.19B at 27.0% = $1.13B EBITDA, less $50M recurring equity comp (the 10-Q shows $93.0M unrecognised over 2.65 yrs), $55M real depreciation, $175M cash interest, tax 25% = owner earnings ~$637M, or $1.27/share. DCF at 9.0% = $28 (bear $19, bull $40). Peer cross-check 16-18x = $28-32. Fair value $31. The REVERSE DCF at $29.06 demands ~$656M of 2027 owner earnings vs our $637M — almost exactly fair. What to watch: Bullish: Q4 adjusted EBITDA margin above 28%, Commercial incremental margins back above 20%, Residential organic sales returning to growth. Bearish: Q3 margin below 26%, any cut to the FY adjusted EBITDA range, or Commercial backlog converting at falling margins into 2027.
