Factors](index=53&type=section&id=Item%203.4.%20Risk%20Factors) The company faces various risks including R&D failure, talent loss, business development challenges, revenue volatility, accounts receivable recovery, market competition, macroeconomic environment, and underperformance of fundraising projects - **R&D failure risk**: CAE software and Physical AI products have high technical thresholds, significant R&D difficulty, and long cycles; if R&D does not align with trends or fails, market competitiveness may be affected[143](index=143&type=chunk)[144](index=144&type=chunk) - **Talent loss and rising technical personnel costs risk**: High-caliber technical talent is scarce; inability to maintain R&D personnel stability or attract excellent talent may impact technological competitive advantage[145](index=145&type=chunk) - **Business development risk**: Downstream customers are primarily concentrated in the military industry; if procurement budgets decrease or new customers are not acquired, revenue growth may fall short of expectations or even decline[146](index=146&type=chunk) - **Annual and seasonal revenue fluctuation risk**: Downstream customers often accelerate project progress in the second half of the year, with concentrated acceptance and settlement in the fourth quarter, leading to seasonal revenue and potential impact on full-year performance[147](index=147&type=chunk)[148](index=148&type=chunk) - **Accounts receivable recovery risk**: Downstream customer payment approval processes are complex and lengthy, resulting in large accounts receivable balances and the risk of non-recovery leading to bad debt losses[149](index=149&type=chunk) - **Increased market competition risk**: National policies encourage independent and controllable industrial software, increasing market participants; foreign competitors have significant advantages, potentially intensifying competition[150](index=150&type=chunk) - **Macroeconomic environment risk**: Complex international situations and impacts on manufacturing development may lead to weak demand from customers for informatization and R&D design software[151](index=151&type=chunk) - **Implementation risk of fundraising investment projects**: Fundraising projects have long construction cycles and require time to realize benefits; if implementation is not smooth or technical development falls short of expectations, profitability may be affected, especially for the "Annual Production of 260 DEMX Underwater Noise Testers Project," which involves production and carries risks of insufficient production management experience[153](index=153&type=chunk) [Key Operating
