Tandem Diabetes Care Inc's operating return on assets (operating ROA) has shown a declining trend over the past eight quarters. The company experienced a significant decrease in operating ROA from Q1 2022 to Q4 2022, followed by further decreases in subsequent quarters. The operating ROA values were negative in the last four quarters, indicating that Tandem Diabetes Care Inc's operating income generated from its assets was insufficient to cover the operating expenses and investment costs. This negative trend in operating ROA points to potential inefficiencies in the company's operations and asset utilization, which may require management's attention to improve profitability and efficiency in the future.
