The company’s intrinsic value of $73.0 suggests potential upside if operational challenges are addressed. LGI’s gross margin of 23.3% remains healthy, but negative free cash flow and high leverage (total debt to equity of 85.9%) highlight the need for prudent financial management in a cyclical sector.

The company posted a strong 24.5% one-year return and remarkable revenue growth of 341.8%, reflecting successful commercialization efforts. However, negative free cash flow and a low ROIC -12.2% indicate ongoing investment needs.
