TransDigm Group Incorporated (NYSE:TDG) is seeking M&A. Kevin Stein President and Chief Executive Officer said during the Fourth Quarter 2021 Earnings Conference Call, "Additionally, we continued to generate significant cash in Q4. We had strong operating cash flow generation of almost $300 million and closed the quarter with approximately $4.8 billion of cash. We expect to steadily generate significant additional cash through 2022.

We continue to look at possible M&A opportunities and are always attentive to our capital allocation. Both the M&A and capital markets are always difficult to predict, but especially so in these times. In regard to the current M&A pipeline, we are still actively looking for M&A opportunities that fit our model.

Acquisition opportunities in the last quarter was still slower than pre-COVID, but we are starting to see some pickup in activity. We remain confident that there is a long runway for acquisitions that fit our portfolio, primarily in the small to midsize opportunities, and look forward to continued M&A activity far into the future".
