Kevin Stein - President, CEO, and Director
Good morning. Thanks for calling in today. First, I'll start off with the usual quick overview of our strategy, a few comments about the quarter and discuss our fiscal 2023 outlook. Then Jorge and Mike will give additional color on the quarter. To reiterate, we are unique in the industry in both the consistency of our strategy in good times and bad as well as our steady focus on intrinsic shareholder value creation through all phases of the aerospace cycle.
To summarize, here are some of the reasons why we believe this. About 90% of our net sales are generated by unique proprietary products. Most of our EBITDA comes from aftermarket revenues, which generally have significantly higher margins and over any extended period have typically provided relative stability in the downturns. We follow a consistent long-term strategy, specifically, we own and operate proprietary aerospace businesses with significant aftermarket content. We utilize a simple, well-proven value-based operating methodology.
