TDG — TransDigm Group Incorporated

The earnings story is positive: FQ3 2026 revenue rose 22.5% YoY to $2.741B, adjusted EPS beat at $10.87 vs. $10.33 consensus, and FY26 guidance was raised to $10.47-10.55B sales and $40.62-41.46 adjusted EPS. But the tape is cautious: TDG is down ~9.2% YTD and below all major moving averages as of 2026-08-27. Analyst consensus is Buy/Moderate Buy with no Sell ratings, so sentiment is split between strong fundamentals and a de-risking price pattern.

Revenue is clearly inflecting upward: quarterly sales went from $2.237B (Jun 2025) to $2.437B (Sep 2025), $2.285B (Dec 2025), $2.544B (Mar 2026) and $2.741B (Jun 2026), with YoY growth accelerating from ~9% to 22.5%. Operating margin has remained remarkably stable in a 43-49% range (latest 44.8%), while diluted EPS rose from $8.47 to $9.39 YoY. Net margin dipped to 19.7% in the latest quarter, likely on interest/tax items, and quarterly free cash flow is volatile with a consistently weak fiscal Q2; TTM FCF is about $1.93B. The acceleration looks structural enough to be reflected in management's raised FY26 guidance rather than a one-off blip.

As of 2026-08-27, TDG sells at 36.0x TTM EPS of $36.77 and roughly 28.9x the consensus forward EPS of $41.07, both below its own 5-year averages of 46.9x P/E and 7.93x P/S (current P/S is 6.63). That is cheap relative to its own history, though not cheap in absolute terms; the PEG of 3.8 is elevated, and the 12.6% yield is mostly special distributions, not an ordinary dividend. Price-to-book is meaningless given negative stockholders' equity.

Earnings estimates are moving up while the stock has fallen from $1,463 to $1,186.48, so the market is effectively ignoring the beat-and-raise cadence and focusing on leverage and rate risk. TDG is priced at ~29x forward EPS, historically a discount; continued execution could drive multiple normalization back toward the mid-30s, whereas an aftermarket slowdown or guidance cut would justify the current de-rating. The playbook favors buying earnings momentum at a technical low only if you can tolerate balance-sheet volatility.

As of 2026-08-27, RSI(14) is 39.76, which is weak but not oversold. Price is -3.62% vs. the 20-day SMA, -5.84% vs. the 50-day SMA, and -6.86% vs. the 200-day SMA, so the stock is in a clear near- and medium-term downtrend below key moving averages. There is no strong timing signal to add yet; a reclaim of the 50-day or an RSI move back above 50 would be a more constructive entry trigger.

• Commercial aftermarket cycle: robust global air travel and fleet utilization keep TDG's high-margin spares and replacement demand strong, and this is the main earnings driver.
• Interest rates and leverage: TDG carries roughly $32.6B in long-term debt and negative equity, so higher-for-longer rates raise interest expense and cap multiple expansion.
• Defense budgets: elevated geopolitical tensions support steady defense OEM and aftermarket demand, providing a countercyclical ballast.
• Supply chain and OEM production: Boeing/Airbus build-rate recovery and airline MRO spending affect both OE shipments and aftermarket attach, creating potential quarterly noise.
• Capital allocation and M&A: the serial bolt-on acquisition model, including the pending $1.07B Prince & Izant deal announced in late July 2026, is integral to the equity story but adds integration and leverage risk.

• FQ4 2026 and full-year earnings expected in early November 2026, plus initial FY2027 commentary; another guidance raise would confirm the inflection.
• Closing and early integration of the pending Prince & Izant acquisition, announced late July 2026, and any further bolt-on deals.
• Continued commercial aftermarket strength and global passenger traffic data.
• Potential Fed rate cuts, which would reduce interest expense and ease debt-service concerns.

• High leverage and negative stockholders' equity: $32.6B long-term debt against -$12.2B equity creates real balance-sheet risk if demand stalls or rates stay high.
• Multiple compression: even at 36x trailing earnings, a growth slowdown or guidance cut could push the stock back toward the low end of its 52-week range near $1,123.61.
• Integration and execution risk on M&A, including paying premium prices for niche acquisitions and relying on pricing power to generate returns.
• Customer concentration and OEM production/supply-chain disruptions, especially around Boeing/Airbus build rates and airline MRO timing.
• Special dividends create a high indicated yield but are discretionary and often debt-funded, not a bond-like recurring dividend.

TransDigm remains one of the highest-quality franchises in aerospace: 59.6% gross margins, 46.2% operating margins, 15.2% ROIC, revenue growth accelerating to 22.5% YoY, and management raising FY26 guidance. As of 2026-08-27, the pullback to $1,186.48 leaves the stock below its own historical multiples despite stronger fundamentals, so it is attractive for long-term investors willing to accept balance-sheet volatility, though the weak technical trend argues for patience on entry timing.

Calculated by applying a 37.0x forward P/E multiple to the consensus forward EPS input of $41.07. The multiple is a deliberate discount to TDG's 5-year average P/E of 46.9x to reflect its negative equity, $32.6B debt load, and weak technical momentum, but a premium to the current ~29x forward multiple to reflect the accelerating aftermarket cycle and raised guidance.
