1. Overview of Business Results

   1. Overview of Business Results

      Consolidated Financial Results of FY2026 Q2 (Semi-Annual) (April 1, 2026 through September 30, 2026)

      (in billion yen)

      	Six months ended September 30, 2025	Six months ended September 30, 2026	As compared to the corresponding period of the previous fiscal year increase (decrease)
      Net sales	526.7	845.2	60.5%
      Operating income	232.4	456.8	96.5%
      Income before income taxes	230.5	510.2	121.3%
      Net income	169.8	368.1	116.8%

      During the six-month period ended September 30, 2026, the global economy as a whole maintained a steady growth trajectory, supported by increased investment related to AI, particularly in the United States. On the other hand, uncertainties persisted amid geopolitical risks, including the situation in the Middle East, and inflation concerns.

      Under such global economic conditions, the semiconductor market continued to grow robustly, driven by accelerating competition in AI technology and broader adoption across society. AI-related high-performance semiconductors such as SoC semiconductors and memory semiconductors for data centers drove market growth.

      In Advantest’s business, as production volumes of AI-related high-performance semiconductors increased and semiconductor complexity grew with the adoption of advanced packaging and other technologies, customers continued to invest actively in our testers. Advantest worked to expand production capacity throughout the supply chain to meet customers’ strong tester demand in a timely manner.

      As a result of the above, net sales were (Y) 845.2 billion (60.5% increase in comparison to the corresponding period of the previous fiscal year), and operating income was (Y) 456.8 billion (96.5% increase in comparison to the corresponding period of the previous fiscal year), due to factors including an increase in net sales and an improved sales mix. In addition, Advantest recorded financial income of approximately (Y) 57.0 billion, primarily attributable to valuation gains on investment securities. As a result, income before income taxes was (Y) 510.2 billion (121.3% increase in comparison to the corresponding period of the previous fiscal year) and net income was

      (Y) 368.1 billion (116.8% increase in comparison to the corresponding period of the previous fiscal year). The depreciation of the yen against the U.S. dollar also contributed to our financial performance, with net sales, operating income, income before income taxes, and net income all reaching record highs in a six-month period. Average currency exchange rates in the current period were 1 USD to 160 JPY (146 JPY in the corresponding period of the previous fiscal year), and 1 EUR to 185 JPY (166 JPY in the corresponding period of the previous fiscal year). The percentage of net sales to overseas customers was 99.4% (98.3% in the corresponding period of the previous fiscal year).

      Conditions of business segments are described below.

      (in billion yen)

      	Six months ended September 30, 2025	Six months ended September 30, 2026	As compared to the corresponding period of the previous fiscal year increase (decrease)
      Net sales	478.0	770.2	61.2%
      Segment income (loss)	240.6	455.6	89.4%

      In this segment, product sales recorded broad-based growth. In particular, sales of SoC test systems grew, driven primarily by rising production volumes and increasing complexity of AI-related SoC semiconductors. With regard to memory test systems, amid growing investment in data centers, sales of products for DRAM and non-volatile memory also increased.

      As a result of the above, net sales were (Y) 770.2 billion (61.2% increase in comparison to the corresponding period of the previous fiscal year), and segment income was (Y) 455.6 billion (89.4% increase in comparison to the corresponding period of the previous fiscal year).

      (in billion yen)

      	Six months ended September 30, 2025	Six months ended September 30, 2026	As compared to the corresponding period of the previous fiscal year increase (decrease)
      Net sales	48.8	75.0	53.7%
      Segment income (loss)	3.0	20.9	584.6%

      In this segment, sales of support services increased as the installed base grew. In addition, sales of consumables such as test interface boards for high-performance SoC semiconductors increased. The segment income in the corresponding period of the previous fiscal year included a gain of approximately (Y) 2.5 billion resulting from the partial divestiture of a business.

      As a result of the above, net sales were (Y) 75.0 billion (53.7% increase in comparison to the corresponding period of the previous fiscal year), and segment income was (Y) 20.9 billion (584.6% increase in comparison to the corresponding period of the previous fiscal year).

   2. Overview of Financial Condition

      Total assets as of September 30, 2026 were (Y) 1,732.1 billion, an increase of (Y) 560.3 billion from March 31, 2026. This was primarily attributable to increases in investment securities of (Y) 364.7 billion, inventories of (Y)

      120.7 billion, and cash and cash equivalents of (Y) 61.8 billion. Total liabilities were (Y) 586.9 billion, an increase of (Y) 210.9 billion from March 31, 2026. This was primarily attributable to increases in bonds of (Y) 89.5 billion, trade and other payables of (Y) 46.5 billion, other current liabilities of (Y) 45.2 billion and income taxes payable of

      (Y) 24.4 billion. Total equity was (Y) 1,145.1 billion. Ratio of equity attributable to owners of the parent was 66.1%, a decrease of 1.8 percentage points from March 31, 2026.

   3. Overview of Cash Flows

      Cash and cash equivalents as of September 30, 2026 were (Y) 401.8 billion, an increase of (Y) 61.8 billion from March 31, 2026. Significant cash flows during the first six months of the fiscal year are described below.

      Net cash provided by operating activities was (Y) 307.0 billion (net cash inflow of (Y) 139.9 billion in the corresponding period of the previous fiscal year). This cash inflow primarily reflected income before income taxes of (Y) 510.2 billion, adjusted for an increase in inventories of (Y) 119.5 billion, income taxes paid of (Y) 109.8 billion, increases in trade and other payables of (Y) 46.7 billion and advance receipts of (Y) 44.2 billion, and non-cash items such as depreciation and amortization and gain on valuation of financial instruments.

      Net cash used in investing activities was (Y) 210.9 billion (net cash outflow of (Y) 17.1 billion in the corresponding period of the previous fiscal year). This cash outflow primarily reflected (Y) 184.4 billion used for purchases of debt instruments.

      Net cash used in financing activities was (Y) 30.4 billion (net cash outflow of (Y) 87.2 billion in the corresponding period of the previous fiscal year). This cash outflow primarily reflected (Y) 105.9 billion used for purchases of treasury shares and (Y) 21.8 billion used for dividend payments, partially offset by proceeds of (Y)

      100.0 billion from issuance of convertible bonds with stock acquisition rights.

   4. Outlook

   Looking at Advantest’s business environment going forward, the semiconductor market is expected to achieve strong year-on-year growth in CY2026, driven by high-performance semiconductors for AI applications amid expanding AI-related investments. Advantest also expects the semiconductor tester market to reach a new record high in CY2026, particularly as inference AI evolves, driven by rising production volumes and increasing complexity of related high-performance semiconductors.

   Based on this outlook and the progress made in the six-month period ended September 30, 2026, Advantest has increased its full-year consolidated forecast for the current fiscal year from the forecast provided as of July 2026 as follows: net sales forecast of (Y) 1,863.0 billion from (Y) 1,714.0 billion; operating income of (Y) 967.0 billion from (Y) 846.0 billion; income before income taxes of (Y) 1,021.5 billion from (Y) 891.0 billion; net income of (Y)

   741.5 billion from (Y) 660.0 billion, respectively. This forecast is based on exchange rate assumptions of 1 USD to 150 JPY and 1 EUR to 170 JPY for the second half of the current consolidated fiscal year.

   While Advantest anticipates that the current situation in the Middle East will lead to increases in certain costs, including logistics expenses, the direct impact on our business and earnings is expected to be limited at this time.

   Meanwhile, demand for key components such as memory semiconductors continues to exceed supply as AI investments expand across industries. Advantest will accelerate efforts to expand production capacity while remaining focused on strengthening supply chain resilience to capture further growth opportunities.

   Advantest will closely monitor changes in the external environment and respond expeditiously and with agility. At the same time, Advantest will strive to expand the value it provides to stakeholders over the mid/long-term by pursuing the measures set out in the Third Mid-term Management Plan.
