Semiconductor Equipment: What ROIC Doesn't Tell You About AMAT's Risk
The semiconductor equipment ROIC spread (LRCX 54% vs AMAT 27%) is observable in any screener. But SEC filings reveal four hidden signals: AMAT faces TWO government investigations plus $181M restructuring, KLAC's AI packaging segment grew 37% with 401bps margin expansion (proving AI demand is real), LRCX's cash conversion is declining -23.7% (hidden stress beneath high ROIC), and ASML's 4-customer concentration creates feast-or-famine cycles.
