KLA advances packaging revenue hits $950M with 70% growth, eyes mid-teens expansion in 2026

KLA is benefiting from strong advanced packaging growth driven by increasing demand for AI and high-performance computing chips. The company reported advanced packaging systems revenue of approximately $950 million in calendar 2025, representing over 70% year-over-year growth, with mid-to-high-teens growth expected in 2026. KLA forecasts the core wafer fabrication equipment market to reach the low $120 billion range in 2026, up from approximately $110 billion in 2025. Advanced packaging is expected to grow to around $12 billion, bringing the total market to the mid-$130 billion range. However, the company faces headwinds including supply constraints, rapidly increasing lead times and tariff impacts of roughly 100 basis points. KLA also faces stiff competition from ASML and Applied Materials in advanced packaging.

KLA leads cash efficiency while Bentley Systems and Paramount fall short

This article discusses three cash-producing stocks, recommending one buy and two sells. **Sell recommendations:** Bentley Systems (BSY), a digital infrastructure software provider, shows concerning signs with average ARR growth of just 12.3% and a projected 3.1 percentage point decline in free cash flow margin next year. Paramount Global (PSKY) struggles with annual sales growth of only 2.7% over five years and weakening returns on capital, with free cash flow margin expected to shrink by 2.7 percentage points. **Buy recommendation:** KLA Corporation (KLAC), a leading semiconductor inspection equipment supplier, maintains a strong 34.4% trailing 12-month free cash flow margin. The article notes that whilst strong cash flow indicates stability, it doesn't guarantee superior returns without proper capital allocation.

KLA stock drops 11.5% despite beating earnings as tariffs and component shortages cloud outlook

KLA Corporation shares fell 11.5% on Friday despite beating Wall Street expectations in its second-quarter earnings report. The semiconductor equipment maker posted revenue of $3.30 billion, up 7.1% year over year, and adjusted earnings of $8.85 per share, surpassing analyst forecasts. However, investors focused on operational challenges highlighted during the earnings call. CFO Bren Higgins warned that component shortages are extending equipment delivery lead times, whilst tariff expenses are pressuring margins. The company is also struggling to meet strong demand for memory-chip manufacturing tools. The sell-off follows a 140% stock gain over the previous 52 weeks. Analysts suggest the decline represents profit-taking rather than fundamental concerns, noting KLA's market position remains strong with limited alternatives for high-end chip-making equipment.
