The latest data point for ONTO's net income in Q1'26 shows $33.75M USD, reflecting a decline from the previous quarter's $10.53M USD in Q4'25 but remaining above the lows seen in late 2025. This value indicates a year-over-year decrease of -47.34%, highlighting ongoing challenges in maintaining profitability momentum. Over the period from Q2'23 to Q1'26, net income started at $25.90M USD and peaked at $64.10M USD in Q1'25, demonstrating strong growth in 2024 with quarterly highs around $53M USD, driven by positive YoY changes up to +104% in Q2'24. However, a sharp reversal occurred from Q2'25 onward, with values dropping to $28.22M USD in Q3'25 and further to $10.53M USD in Q4'25 amid negative YoY growth exceeding -78%, suggesting volatility and potential sector headwinds despite the bar chart's visualization of an initial upward trend.
