Adjusted EBITDA by Segment

We use Adjusted EBITDA as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from, and is not intended to represent an alternative to, our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for investors about our operating performance, better facilitates period to period comparisons and is widely used by analysts, lenders, rating agencies and other interested parties. Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies, including those in our industry. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of Strategic Land Solutions acres sold and special items.

We reconcile Adjusted EBITDA to net earnings for the consolidated company and to operating income (loss) for the business segments, as those are the most directly comparable U.S. GAAP measures for each.

The table below reconciles Adjusted EBITDA for the quarter ended September 30, 2026:

Adjusted FAD

We use Adjusted Funds Available for Distribution (Adjusted FAD) to evaluate the company’s liquidity and measure cash generated during the period (net of capital expenditures and significant non-recurring items) that is available for dividends, repurchases of common shares, debt reduction, acquisitions and other discretionary and nondiscretionary capital allocation activities. Adjusted FAD should not be considered in isolation from, and is not intended to represent an alternative to, our results reported in accordance with U.S. GAAP. However, we believe the measure provides meaningful supplemental information for investors about our liquidity. Adjusted FAD, as we define it, is net cash from operations adjusted for capital expenditures and significant non-recurring items. Our definition of Adjusted FAD may be different from similarly titled measures reported by other companies, including those in our industry. We reconcile Adjusted FAD to net cash from operations, as that is the most directly comparable U.S. GAAP measure.

The table below reconciles Adjusted FAD to net cash from operations:

Net Earnings and Net Earnings per Diluted Share Before Special Items

We use net earnings before special items and net earnings per diluted share before special items as key performance measures to evaluate the performance of the consolidated company. These measures should not be considered in isolation from, and are not intended to represent an alternative to, our results reported in accordance with U.S. GAAP. However, we believe the measures provide meaningful supplemental information for investors about our operating performance, better facilitate period to period comparisons and are widely used by analysts, lenders, rating agencies and other interested parties.
