Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1 - Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all material adjustments (consisting of normal, recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the quarter and nine months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending September 30, 2022. The accompanying Condensed Consolidated Balance Sheet at September 30, 2021 has been derived from the audited financial statements at that date but does not include all of the information and notes required by generally accepted accounting principles for complete financial statements. On October 1, 2020, the Company acquired the Blaw-Knox paver line and associated assets, including inventory, fixed assets and related intellectual property, from Volvo CE. The acquisition provided the Company entry into the asphalt paver sector of the asphalt industry. The acquisition was accounted for as a business combination under ASC 805, “Business Combinations.” The initial purchase price of approximately $14.4 million, which was subject to post-closing adjustments, was funded by cash on hand. After post-closing adjustments transacted during the quarter ended March 31, 2021, the final purchase price was $13.8 million, including $10.4 million in inventory and $3.4 million in fixed assets. There were no liabilities assumed. The accompanying condensed consolidated financial statements as of June 30, 2022 and September 30, 2021, and for the quarters and nine months ended June 30, 2022 and 2021, include the assets, liabilities and operating results of the paver line as of and for the periods then ended. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended September 30, 2021 filed with the Securities and Exchange Commission on December 17, 2021. Recent Accounting Pronouncements There were no accounting pronouncements recently issued or newly effective that had or are expected to have a material impact on the Company’s consolidated financial statements. COVID-19 Pandemic The Company continues to monitor and evaluate the risks to public health and the overall business activity related to the COVID-19 pandemic, including impacts on its employees, customers, suppliers and financial results. As of the date of issuance of this Quarterly Report, the Company’s operations have not been significantly impacted. However, the full impact of the COVID-19 pandemic continues to evolve subsequent to the quarter ended June 30, 2022 and as of the date this Quarterly Report is issued. As such, the full magnitude that the COVID-19 pandemic will have on the Company’s financial condition and future results of operations is uncertain. Management continues to monitor the situation on the Company’s financial condition, operations, suppliers, industry, customers, and workforce. As the spread of COVID-19 and its variants continues, the Company’s ability to meet customer demands for products may be impacted or its customers may experience adverse business consequences due to COVID-19 and its variants. Reduced demand for products or ability to meet customer demand (including as a result of disruptions at the Company’s suppliers) could have a material adverse effect on its business operations and financial performance. Global, market and economic conditions may negatively impact our business, financial condition and share price Concerns over inflation, geopolitical issues, global financial markets and the COVID-19 pandemic have led to increased economic instability and expectations of slower global economic growth. Our business may be adversely affected by any such economic instability or unpredictability. Russia’s invasion of Ukraine and related sanctions has led to increased oil and natural gas prices. Such sanctions and disruptions to the global economy may lead to additional inflation and may disrupt the global supply chain and could have a material adverse effect on our ability to secure supplies. The increased cost of oil, along with increased or prolonged periods of inflation, would likely increase our costs in the form of higher wages, further inflation on supplies and equipment necessary to operate our business. There is a risk that one or more of our suppliers could be negatively affected by global economic instability, which could adversely affect our ability to operate efficiently and timely complete our operational goals.
