AI Insight: POWI Financial Trends

Revenue has flatlined between $103M–$119M for eight quarters while operating income collapsed to near-zero, erasing the profitability seen in Q3 2024.

• Operating income fell from $12M in Q3 2024 to $1M in Q1 2026, with two consecutive loss quarters (Q2–Q3 2025) in between.

• Revenue range has been narrow — $103M to $119M across all eight quarters — signaling stalled top-line growth.

• Operating cash flow remained relatively resilient at $20M–$30M in recent quarters despite near-zero operating income.

• Equity declined from $750M in Q4 2024 to $672M in Q1 2026, a $78M erosion over five quarters.

⚠ Net income of $3M in Q1 2026 versus operating loss quarters in mid-2025 — watch whether profitability recovery is sustained.

⚠ Equity has contracted $78M since Q4 2024 with no debt visible; likely driven by buybacks or losses — monitor pace.

⚠ Revenue dipped to $103M in Q4 2025 then rebounded to $108M — any further sequential decline would confirm demand weakness.

AI Insight: POWI Ratio Trends

POWI's profitability remains structurally weak, with TTM operating margin at just 1.1% after two consecutive quarters of operating losses in mid-2025.

• Operating margin swung from -3.3% in Q3 2025 to 8.5% in Q4 2025, but collapsed back to 1.3% in Q1 2026.

• ROIC peaked at 6.2% in Q3 2024, turned negative at -2.4% in Q3 2025, and has only partially recovered to 0.9% in Q1 2026.

• TTM net profit margin of 3.7% and ROA of 2.1% reflect a full-year profitability picture that is deeply subdued versus Q3 2024 highs.

⚠ Q4 2025 showed sharp recovery (OpMargin 8.5%, ROIC 5.2%) — monitor whether Q2 2026 sustains this or reverts as Q1 2026 suggests.

⚠ Two straight quarters of negative operating income (Q2–Q3 2025) raise questions about cost structure and demand sustainability.
