[1] Certain general and administrative costs (including executive compensation, corporate legal fees, audit fees, investor relations, and insurance) are shared across both segments. For internal reporting purposes, such costs are allocated to each segment based on an estimate of the proportion of management time and corporate resources utilized by each segment. Costs directly attributable to a segment are charged directly to that segment. For the three and six months ended June 30, 2026 and 2025, the Regenerative Biotech segment bore substantially all general and administrative expense, as the Consumer Health Products segment incurred minimal shared corporate overhead.
[2] “Other segment items” for the Regenerative Biotech segment consists primarily of net interest income earned on money market balances and other miscellaneous income, partially offset by interest expense on insurance premium financing. For the Consumer Health Products segment, other segment items consist of foreign currency transaction effects and other minor income items. The other segment items line represents the arithmetic difference between segment revenues, less the significant expense categories disclosed above, and the reported segment net loss, in accordance with ASC 280-10-50-26B.
