Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments necessary to present fairly the financial position as of July 31, 2026 and April 30, 2026, the results of operations for the three months ended July 31, 2026 and 2025, and shareholders' equity and cash flows for the three months ended July 31, 2026 and 2025. Although management believes that the disclosures are adequate to make the information presented not misleading, it is suggested that these interim condensed consolidated financial statements be read in conjunction with the Company’s most recent audited financial statements and notes thereto. Additionally, see the most recent audited financial statements for our consideration of new accounting pronouncements issued prior to this fiscal year. During the quarter, the Company elected to early adopt ASU 2026‑02, Environmental Credits and Environmental Credit Obligations (Topic 818). The standard establishes guidance for the recognition, measurement, presentation, and disclosure of environmental credits and environmental credit obligations. The new standard impacts the Company's accounting for renewable identification numbers ("RINs"). The Company adopted the guidance on a retrospective basis effective May 1, 2026. The effect of applying the guidance to prior-period financial statements was not material and no cumulative-effect adjustment to the opening balance of retained earnings was required. Refer to Note 3 for the required disclosures and details of the new accounting policy.
