    On Simply Wall St's most followed narrative, Gibraltar Industries screens as materially undervalued, with a fair value of $75.25 against the last close at $32.47 and a discount rate of 11.38% applied to its future cash flows.

    The plan to reduce net leverage from roughly 3.9x to about 2.5x adjusted EBITDA within 24 months of the OmniMax close, funded by free cash flow of about 8% of sales, working capital initiatives, and possible non core divestitures, is aimed at lowering interest expense and lifting future net income.

    Result: Fair Value of $75.25 (UNDERVALUED)

    Still, Gibraltar Industries carries about US$1.2b in net debt and leans heavily on Residential exposure, so weaker roofing demand or slower deleveraging could quickly challenge this thesis.
