While the impact of inflation has been challenging, the Company has taken actions to limit this pressure, including adjusting the pricing of its products and services. Changes in macroeconomic conditions arising from various reasons, such as the ongoing wars between Russia and Ukraine and Israel and Hamas, inflation, rising interest rates, labor force availability, sourcing, material delays and global supply chain disruptions could have a material adverse effect on the Company’s business, financial condition and results of operations. The Company believes that based on the information presented above and its quarterly management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next twelve six September 30, 2024 may no
