Customer Concentration and Payment Terms - The company has a high customer concentration, with revenue from the top five customers accounting for 79.4% in 2022, decreasing to 73.7% in the first half of 2025 [23][25]. - The average collection period for receivables has increased from 126 days in 2022 to 200 days in the first half of 2025, indicating pressure from high customer concentration [25]. Market Position and Future Outlook - Mainline Technology is positioned as a leader in the autonomous truck market, but it must demonstrate a sustainable business model to attract investor confidence as it approaches its IPO [26][27].
