Rohm (6963): J.P. Morgan reiterates Overweight on Rohm as semiconductor recovery and a potential Toshiba integration lift its FY2028 profit outlook.

Overview

J.P. Morgan maintains its Overweight rating and ¥8,000 December 2027 target for Rohm. Its thesis rests on a recovery in analog and discrete semiconductor markets, stronger power-semiconductor demand from AI servers, operational leverage from rising utilization and pricing actions, and the possible strategic value of integrating Toshiba Electronic Device Solutions' semiconductor business.

Core views

J.P. Morgan expects Rohm's earnings to expand from FY2027 as analog and discrete semiconductor demand recovers in industrial equipment and automotive applications and as power-semiconductor supply tightens, particularly for AI servers. It raises operating-profit forecasts to ¥63.9 billion for FY2026 from ¥62.8 billion, ¥115.7 billion for FY2027 from ¥93.8 billion, and ¥152.0 billion for FY2028 from ¥120.1 billion. The FY2027 and FY2028 forecasts stand well above Bloomberg consensus of ¥60.1 billion and ¥83.5 billion, respectively. The revised view also reflects a forex assumption change to ¥160/$ from ¥155/$ and less caution on profitability beyond FY2027. The operating recovery is expected to be driven by stronger utilization and a more favorable product mix. J.P. Morgan assumes utilization of 60% in 1Q and 70% in 2Q, compared with 55% in the prior fiscal year's 4Q, and estimates that every 10-percentage-point increase in utilization adds roughly ¥10 billion to quarterly operating profit. It sees spare front-end capacity for approximately 100V Si-MOSFETs at Rohm while Tier 1 producers face strain and OSAT back-end capacity becomes harder to secure. Rohm's high in-house back-end production ratio is viewed as a competitive advantage. The report expects growth in PMICs, hot-swap controllers and HDD DrMOS products within LSI, as well as 100V Si-MOSFETs and 1,200V SiC-MOSFETs in discrete devices. It also notes that faster development and commercialization may be needed in 3,000V and 1,700V SiC-MOSFETs and 650V and 100-150V GaN HEMTs as demand expands. The report expects the loss-making SiC business to improve from 2Q as the effects of selling inventory before prior impairments and the use of low-quality wafers fade, allowing fixed-cost reductions to take effect. It also models approximately ¥4.0 billion of FY2026 price pass-through for higher gold prices, within a ¥4.0-5.0 billion range. For FY2027, it assumes 70% of customers shift to copper wire, reducing costs by roughly ¥10-15 billion. Rohm plans around ¥5.0 billion of price increases in 2H, and J.P. Morgan believes further increases are possible because Rohm raised prices by only high single digits in 2020-2022 while competitors raised them 20-30%. A possible integration with Toshiba Electronic Device Solutions is the report's principal strategic upside. J.P. Morgan now estimates a potential acquisition price of ¥800 billion to ¥1 trillion, versus its prior ¥400-600 billion assumption, based on Toshiba's semiconductor business generating assumed next-fiscal-year operating profit of ¥50.0 billion and net profit just under ¥40 billion at a 20-25x P/E. It nevertheless considers the transaction worthwhile because Rohm's Toshiba shareholdings are estimated at about ¥1.2-1.3 trillion after tax at a Kioxia share price around ¥55,000. The acquisition could strengthen Rohm in low- and medium-voltage power semiconductors, including 100V Si-MOSFETs where Toshiba ranked second or third globally in April-June 2026; improve its position in 3,000V/1,700V SiC-MOSFETs for SST applications; add 12-inch discrete-production lines; and bring photocouplers, CIS, high-end logic products and engineering talent. The report is more cautious on potential integration with Mitsubishi Electric's power-semiconductor business, arguing that Rohm should reconsider it if it cannot control the combined operation. On a simple aggregate basis, J.P. Morgan estimates Rohm and Toshiba Electronic Device Solutions could generate nearly ¥1 trillion in sales and just under ¥100 billion in operating profit in FY2026. If tight analog and discrete supply for AI servers persists, combined FY2028 sales could reach around ¥1.2 trillion and operating profit around ¥220 billion; fixed-cost synergies could lift operating profit to around ¥250 billion and net profit to around ¥175 billion. Applying a 20x P/E to these FY2028 estimates, the report sees potential market capitalization of around ¥3.5 trillion. The unchanged ¥8,000 December 2027 target now combines a ¥4,000 per-share after-tax value for Rohm's Toshiba stake with ¥4,000 per share from a zero-growth ROIC model using FY2028 estimates. The model uses EV/IC = ROIC/WACC, with a 2.57% risk-free rate, 5.15% risk premium, beta of 1.0 and 7.15% WACC. J.P. Morgan estimates Rohm owns just under 15% of Toshiba, values Toshiba at about ¥8.5 trillion assuming FY2026 operating margin recovers to 12%, and estimates Rohm's Toshiba holding at about ¥1.8 trillion after tax, or ¥4,000 per share. This replaces the prior target construction of ¥4,600 per share for the stake and ¥3,400 from the ROIC model.

Analysis framework

J.P. Morgan updates earnings estimates after 1Q FY2026 and tests the recovery thesis through end-market demand, utilization, capacity constraints, product trends, cost actions and pricing. It then values Rohm by combining a ROIC-based operating-business valuation with the estimated after-tax value of Rohm's Toshiba holding, and separately models the potential earnings contribution of a Toshiba semiconductor-business integration.

• Rohm (6963.T)

  Primary covered company expected to benefit from recovering analog and discrete demand, AI-server power-semiconductor demand, higher utilization, pricing and copper-wire cost reductions.

  Strengths

  Spare Si-MOSFET front-end capacity, high in-house back-end production ratio, potential utilization leverage, and valuable Toshiba shareholdings.

  Weaknesses

  SiC remained significantly loss-making in 1Q, and Rohm may need faster product development in certain SiC and GaN categories.

  Risks

  Restructuring delays, a delayed semiconductor-cycle recovery, weaker AI-cycle conditions, yen appreciation and a decline in Toshiba's share price.

• Toshiba Electronic Device Solutions

  Potential acquisition and integration target whose semiconductor business could expand Rohm's low- and medium-voltage power-semiconductor portfolio and manufacturing capabilities.

  Strengths

  Position in 100V Si-MOSFETs, 12-inch discrete lines, additional products and engineering resources.

  Weaknesses

  Potential purchase price has risen to an estimated ¥800 billion to ¥1 trillion.

  Comparison

  The report estimates the combined entity could reach around ¥1.2 trillion in FY2028 sales and ¥220-250 billion in operating profit under favorable conditions.

  Risks

  The economic value depends on transaction execution, sustained semiconductor tightness and realization of fixed-cost synergies.

Impact & implications

The report argues that Rohm's valuation increasingly depends on both improving semiconductor-cycle fundamentals and the strategic and financial value embedded in its Toshiba holding. A successful Toshiba semiconductor-business integration could broaden Rohm's product capabilities and materially raise its earnings ceiling, while the existing ¥8,000 target is supported by the standalone recovery and stake valuation.

Risks

• Delays in Rohm's restructuring could weaken the earnings-recovery path.
• A decline in Toshiba's share price would reduce the value attributed to Rohm's Toshiba holding.
• A delayed recovery in the semiconductor cycle could reduce demand, utilization and profitability.
• A weaker AI cycle could soften demand for power semiconductors.
• Yen appreciation could be adverse to the outlook.

What to watch

• Whether analog and discrete semiconductor supply-demand conditions tighten further and support price increases.
• Rohm's utilization-rate progression and the resulting operating-profit leverage.
• Demand trends for AI-server-related Si-MOSFETs, industrial equipment, automotive applications and HDD DrMOS.
• Execution of copper-wire conversion and further price adjustments.
• Developments in a potential integration with Toshiba Electronic Device Solutions, including transaction price, control and fixed-cost synergies.
• Changes in Kioxia's share price and the resulting value of Rohm's Toshiba holding.
