KLA stock holds its ground as fiscal 2025 shows higher revenue and profit

KLA Corporation (US4824801009) reported fiscal 2025 revenue of $10.49 billion and diluted EPS of $30.99, with fourth-quarter revenue at $3.06 billion and operating margin at 45.9% in the companys latest annual filing. The stock is tied to a business that still generates large, recurring demand from semiconductor process control, and the numbers frame the market case more clearly than any short-term headline.

Fiscal 2025 revenue at $10.49 billion

In fiscal 2025, KLA said revenue increased to $10.49 billion, compared with $9.67 billion in fiscal 2024. That is an increase of about 8.5%, a useful comparison for investors because it shows the company extending growth even after a strong prior year.

Net income for fiscal 2025 came in at $3.26 billion, versus $3.01 billion a year earlier, while diluted EPS rose to $30.99 from $24.35. The combination of higher sales and higher earnings per share matters because it points to operating leverage, not just top-line expansion.

Fourth-quarter margin stayed high

KLA reported fourth-quarter revenue of $3.06 billion for fiscal 2025, up from $2.57 billion in the same quarter of fiscal 2024. Operating margin in that quarter reached 45.9%, compared with 43.5% a year earlier, showing that profitability remained close to peak levels even as the business scaled.

The company also posted fourth-quarter diluted EPS of $8.53, up from $6.54 a year earlier. That 30.3% year-over-year increase is the clearest quantitative comparison in the latest period and helps explain why the market typically treats KLA as a margin story as much as a revenue story.

Margin over revenue growth

KLAs latest reported quarter suggests the market still values the company for discipline as much as for scale. With quarterly operating margin at 45.9% and full-year diluted EPS at $30.99, the earnings profile remained stronger than simple revenue growth might imply.

For context, the fourth quarter delivered $3.06 billion in sales after $2.57 billion in the same period a year earlier. That 19.1% revenue increase outpaced the full-year growth rate, which is a sign that the latest quarter was the stronger part of the fiscal 2025 run.

Semiconductor tools still lead

KLAs core business remains process control and related inspection tools for semiconductor manufacturing, the product set that supports the companys revenue and margin profile. The annual filing shows why that niche matters: fiscal 2025 gross profit, operating income, and EPS all moved higher alongside revenue.

The companys fiscal 2025 operating income reached $4.99 billion, up from $4.41 billion in fiscal 2024. That 13.2% increase was faster than revenue growth and is another indication that mix and scale continued to support profitability.

Stock level and valuation context

As of the latest reported annual data, KLA did not rely on a single quarter to make its case. Instead, the company paired $10.49 billion in fiscal 2025 revenue with $3.26 billion in net income and a 45.9% fourth-quarter operating margin, a combination that keeps the stock closely tied to execution in semiconductor capital equipment.

KLA Corporation shares traded on Nasdaq under the symbol KLAC. The latest dated price data should be read together with the fiscal 2025 earnings profile, because both the market value and the operating numbers point to the same question: whether high margins can hold through the next cycle.

Process control products

KLAs process control systems are the most representative product line for understanding the companys financial results. The business is built around inspection, metrology, and related tools used in chip fabrication, and that link between product depth and earnings quality is visible in the fiscal 2025 margin and EPS figures.

Nasdaq quote context

KLA Corporation shares are listed on Nasdaq as KLAC. The companys fiscal 2025 results provide the main numeric frame here: $10.49 billion in revenue, $3.26 billion in net income, and $30.99 in diluted EPS, all reported in the latest annual filing. Those figures matter more than a short-term slogan, because they show how the stock is being supported by a still-profitable core business.
