1. Q2 FY2026 Financial Highlights (Non-GAAP)

In the second quarter (April–June), Renesas recorded high growth rates in both revenue and profit. Revenue reached ¥405.3 billion (+24.8% YoY, +8.8% QoQ) , surpassing the median company forecast (¥388 billion) by 4.5% .

In terms of profitability, the gross margin was 58.1% (+1.1 points vs. forecast) and the operating margin was 32.7% (+3.7 points vs. forecast), with gross profit reaching ¥132.7 billion (+¥40.9 billion, +44.5% YoY) .

[Why this slide is important]

The slide above (Page 4) provides the most fundamental and critical data for an overview of the consolidated Non-GAAP performance. It covers comparisons with the same period last year (YoY) and the previous quarter (QoQ), as well as deviations from company forecasts.

Beyond the revenue-boosting effect of a weaker yen , the background to these figures includes improved product mix toward high-margin products and manufacturing cost reduction efforts that supported profit margins. While the exchange rate environment—¥159 to the US dollar (a ¥13 depreciation YoY) and ¥185 to the euro (a ¥23 depreciation YoY)—contributed positively, the high operating margin of over 30% is fundamentally supported by volume growth and an improved business structure.

3. Segment Performance Analysis

The trends for the two core segments supporting Renesas' performance are as follows:

[Why this slide is important]

The slide above (Page 12) provides a detailed breakdown of revenue and gross profit fluctuations by segment. It is essential for structurally understanding the sources of the company's earning power.

① Industrial, Infrastructure, and IoT Business

• Revenue : ¥216.3 billion (+40.0% YoY, +10.4% QoQ)
• Gross Margin : 60.7% (+0.3 points YoY)
• Operating Profit : ¥69.0 billion (Operating Margin 31.9%)

Driven by increased demand for analog ICs and power semiconductors for data centers, as well as the recovery of industrial IoT equipment, this segment has made a significant leap forward, acting as the main engine accounting for more than half of total company revenue . With a gross margin exceeding 60%, its contribution as a high-profit segment is remarkable.

② Automotive Business

• Revenue : ¥187.1 billion (+15.9% YoY, +9.0% QoQ)
• Gross Margin : 55.3% (+2.9 points YoY)
• Operating Profit : ¥64.4 billion (Operating Margin 34.4%)

Demand for automotive domain control MCUs and power ICs for ECUs remained solid. The operating margin improved significantly by +11.1 points YoY, demonstrating excellent profitability (34.4% operating margin) in the automotive business as well .

4. Inventory Status and Channel Control

Inventory metrics (internal inventory and sales channel inventory), which are closely watched as leading indicators for semiconductor manufacturers, are being appropriately controlled.

• Days of Inventory (DOI) : While the inventory value increased in Q2 due to higher work-in-progress, the turnover days are being controlled within an appropriate range in line with revenue expansion.
• Weeks of Inventory (WOI) : As a result of very strong sell-through (actual demand) in both the Automotive and Industrial/Infrastructure/IoT segments, WOI showed a slight decrease (trending toward optimization) compared to the previous quarter, despite ongoing inventory replenishment to channels.

For Q3, the company plans to continue expanding finished goods and die bank inventory to meet robust market demand.

5. Front-end Utilization and CapEx Trends

On the production side, front-end utilization rates are being gradually increased in line with the recovery in demand. In particular, the increase in utilization of the 12-inch lines is notable, and the absorption of fixed manufacturing costs has contributed to the maintenance and improvement of gross margins.

Regarding Capital Expenditure (CapEx), after a temporary peak in Q1 (¥94 billion), it returned to normal investment discipline in Q2 at ¥22.6 billion (5.6% of revenue) . This demonstrates a commitment to avoiding unnecessary capacity expansion while focusing resources on advanced processes and high-efficiency lines.

6. Structural Reform: Phased Closure of Takasaki Factory and R&D Enhancement

As a key decision for mid-to-long-term profitability improvement and production system optimization, the phased production termination of the Takasaki factory was announced (Page 18).

• Background : To address structural environmental changes, including the aging of the 6-inch line, the end of maintenance support for manufacturing equipment and utilities, and the discontinuation of production material supplies.
• Plan : Production is scheduled to be phased out over the next 2–3 years , leading to the factory's closure.
• Maintenance of R&D Functions : The company plans to maintain and strengthen the technical capabilities and R&D functions currently housed at the Takasaki factory (analog ICs and power semiconductors for data centers and automotive) by keeping them at the current or nearby locations.
• Personnel Considerations : The basic policy is to maintain and secure employment, providing maximum support for career transitions and reassignments.

By phasing out the aging small-diameter (6-inch) line and shifting resources to high-efficiency production lines such as 12-inch, further improvements in gross margins are expected in the future.

7. Disaster Response: Impact of the Kumamoto Earthquake (As of July 30)

The impact of the "Reiwa 8 Kumamoto Earthquake" that occurred in July 2026 and the company's response have been reported (Page 19).

• Human Impact : Safety of all employees has been confirmed; no human casualties .
• Kawashiri Factory (Kumamoto City, Front-end site) : Safety checks in the cleanroom are complete, and impact assessments on equipment and work-in-progress are underway. Production is scheduled to resume sequentially from August 5 .
• Nishiki Factory (Kuma District, Back-end site) : Safety checks in the cleanroom are complete, and production resumed sequentially from the night of July 29 .

Through the rapid activation of the Business Continuity Plan (BCP), a system is in place to minimize the impact on the supply chain.
