While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.

Our Top 5 Analyst Questions From TransDigm’s Q3 Earnings Call

• Scott Mikus (Melius Research) asked if management would consider expanding M&A beyond aerospace and defense. CEO Michael J. Lisman replied that current efforts remain focused on core markets, though future diversification is possible.

• Kristine Liwag (Morgan Stanley) sought details on the F-47 program’s contribution and overall defense contract wins. Management noted a strong pipeline of new business but declined to share specifics, citing competitive reasons.
