MICROSOFT CORP · 2026-04-29 · Importance 55 · Surprise 50 · No source text
Operating expenses increased $1.5 billion or 9% in the quarter primarily driven by investments in R&D compute capacity, AI talent, and data to support product development across the portfolio. Research and development expense was $8,915 million for the quarter, up $717 million or 9% year-over-year, and sales and marketing increased $602 million or 10% driven by higher Copilot advertising. General and administrative expense rose $194 million or 11% for the quarter, primarily due to higher legal expenses; total company headcount declined year‑over‑year despite these cost increases. Management attributes operating expense growth to strategic AI and product investments and higher advertising for Copilot.
