owned consolidated subsidiaries for the quarter ended September 30, 2023 due to the sale of Changzhou Eminence Biotechnology Co., Ltd. (Eminence) in the first quarter of fiscal 2023. Revenue from partially-owned consolidated subsidiaries was $2.0 million for the quarter ended September 30, 2022.
Our non-GAAP financial measures for adjusted gross margin, adjusted operating margin, and adjusted net earnings, in total and on a per share basis, exclude stock-based compensation, the costs recognized upon the sale of acquired inventory, amortization of acquisition intangibles, acquisition related expenses inclusive of the changes in fair value of contingent consideration, and other non-recurring items including non-recurring costs, goodwill and long-lived asset impairments, and gains. Stock-based compensation is excluded from non-GAAP adjusted net earnings because of the nature of this charge, specifically the varying available valuation methodologies, subjection assumptions, variety of award types, and unpredictability of amount and timing of employer related tax obligations. The Company excludes amortization of purchased intangible assets, purchase accounting adjustments, including costs recognized upon the sale of acquired inventory and acquisition-related expenses inclusive of the changes in fair value contingent consideration, and other non-recurring items including gains or losses on legal settlements, goodwill and long-lived asset impairment charges, and one-time assessments from this measure because they occur as a result of specific events, and are not reflective of our internal investments, the costs of developing, producing, supporting and selling our products, and the other ongoing costs to support our operating structure. Additionally, these amounts can vary significantly from period to period based on current activity. The Company also excludes revenue and expense attributable to partially owned consolidated subsidiaries in the calculation of our non-GAAP financial measures as the revenues and expenses are not fully attributable to the Company.
The Company’s non-GAAP adjusted operating margin and adjusted net earnings, in total and on a per share basis, also excludes stock-based compensation expense, which is inclusive of the employer portion of payroll taxes on those stock awards, restructuring, gain and losses from investments, as they are not part of our day-to-day operating decisions (excluding our equity method investment in Wilson Wolf as it is certain to be acquired in the future) and certain adjustments to income tax expense. Additionally, gains and losses from investments that are either isolated or cannot be expected to occur again with any predictability are excluded. Costs related to restructuring activities, including reducing overhead and consolidating facilities, are excluded because we believe they are not indicative of our normal operating costs. The Company independently calculates a non-GAAP adjusted tax rate to be applied to the identified non-GAAP adjustments considering the impact of discrete items on these adjustments and the jurisdictional mix of the adjustments. In addition, the tax impact of other discrete and non-recurring charges which impact our reported GAAP tax rate are adjusted from net earnings. We believe these tax items can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs and/or income associated with historical trends and future results.
The Company periodically reassesses the components of our non-GAAP adjustments for changes in how we evaluate our performance, changes in how we make financial and operational decisions, and considers the use of these measures by our competitors and peers to ensure the adjustments are still relevant and meaningful.
Readers are encouraged to review the reconciliations of the adjusted financial measures used in management's discussion and analysis of the financial condition of the Company to their most directly comparable GAAP financial measures provided within the Company's consolidated financial statements.
