TransDigm Group (TDG -4.1%) slips today after its FQ4 missed estimates across the board. The company also issued a downbeat view for FY13. It now forecasts its EPS to come in around $6.54 - $6.98 on revenues of $1.8B - $1.9B. The Street view is for an EPS of $7.58 on revenues of $1.95B. The stock has been hammered over the past few weeks due to concerns about a potential sequestration if the fiscal cliff issue isn't resolved. The company's products include military aircraft components, and the already deep Pentagon budget cuts are liable to get worse if that happens.
