Goldman Sachs maintains its Buy rating on MARUWA and sees room for upward revisions to AI and semiconductor application guidance

Overview

This report reviews Goldman Sachs’ takeaways from MARUWA’s 1Q3/27 results briefing. The company disclosed the latest demand and capacity plans for AI, CPO, automotive, and semiconductor applications. Goldman Sachs viewed the tone of the briefing as positive, particularly regarding order visibility, inquiry strength, and accelerated capacity deployment in AI and semiconductor applications, supporting the possibility of further upward guidance revisions.

Core views

Goldman Sachs maintains its Buy rating on MARUWA. The core thesis is that the company’s structural growth story centered on AI applications is not yet fully reflected in the current share price. MARUWA has shifted from highly commoditized, cyclical products subject to intense price competition toward customized, high-margin niche ceramic products, establishing competitive advantages in high-growth segments. Earnings growth in FY3/27-FY3/29 is expected to be driven mainly by thermal substrates for optical transceivers, xEVs, and quartz/SiC products for semiconductor equipment.

Analysis framework

The report’s assessment is based primarily on the company’s 1Q3/27 results briefing, management commentary on demand and capacity in each application area, and Goldman Sachs’ existing earnings forecasts and valuation framework. Goldman Sachs did not change its FY3/27-FY3/29 operating profit forecasts, but adjusted quarterly phasing and made minor downward revisions of less than 1% to EPS and net profit forecasts.

Methodology notes

• Valuation methodologyEV/EBITDA

  Target price based on FY28E EBITDA and a 12.5x multiple

  Goldman Sachs’ 12-month target price is ¥89,000, implying FY27/28E P/E multiples of 29x/23x; the applicable EV/EBITDA multiple is derived from the historical correlation between EBITDA margins and EV/EBITDA multiples.

• Factor analysisGS Factor Profile

  Comparison of growth, financial returns, valuation multiples, and composite percentile rankings

  Goldman Sachs’ factor framework measures growth using forward sales, EBITDA, and EPS growth; financial returns using ROE, ROCE, and CROCI; and valuation multiples using P/E, P/B, and EV/EBITDA, producing composite percentile rankings.

• M&A frameworkM&A Rank

  A score from 1 to 3 measuring the probability of becoming a potential acquisition target

  Goldman Sachs uses its global M&A framework to assess the likelihood of a company being acquired; 1 represents high probability, 2 medium probability, and 3 low probability. Some ratings incorporate the target price.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• MARUWA (5344.T)

  Covered company; a Japanese supplier of ceramic materials and electronic components benefiting from demand for AI, CPO, xEVs, and semiconductor equipment.

  Strengths

  High share in customized, high-margin niche markets; improved order visibility for AI applications; strong semiconductor and CPO demand; multiple capacity deployment plans brought forward.

  Weaknesses

  1Q operating margin declined sequentially, mainly due to low-margin work-in-process inventory produced in 4Q and shipped in 1Q; execution of capacity expansion remains important.

  Comparison

  The rating is relative to Goldman Sachs’ universe of covered Japanese electronic component and related companies, including Kyocera, Murata Mfg., TDK, Renesas Electronics, and Rohm.

  Risks

  End-market investment in AI/general-purpose servers, xEVs, and SPE may fall below expectations; supply-chain disruptions and inventory adjustments may reduce end-product demand; substitution technologies may emerge.

Key data

• Full-year sales growth guidance for AI applications+110%Previously +50%; the increase reflects the conversion of strong initial-year forecasts into confirmed orders and improved visibility.
• 1Q sales for the communications business¥9.2 bnFull-year year-on-year sales growth guidance for the business was raised from +23% to +48%.
• Launch timing for CPO-related products4QThe company confirmed a 4Q launch; orders are already substantial, with mass production planned for FY3/28.
• 1Q sales for the automotive business¥3.5 bnSales of xEV applications remained solid, with full-year year-on-year sales growth guidance raised from +2% to +6%.
• 1Q sales for the semiconductor business¥2.2 bnThe company expects approximately ¥3 bn in 2Q and more than ¥3 bn per quarter in 2H.
• Full-year sales growth guidance for semiconductor applications+20%Previously +14%; management’s comments suggest further upside remains possible amid strong current inquiries.
• Miharu plant capacity increaseAt least +50%The planned start-up of two new buildings has been brought forward from 2H to 2Q.
• 12-month target price¥89,000Goldman Sachs maintains its target price and Buy rating.

Impact & implications

For investment implications, the briefing strengthened the medium-term growth thesis that MARUWA will benefit from demand related to AI servers, CPO, thermal materials for optical transceivers, and semiconductor equipment. If capacity at Seto and Miharu comes online ahead of schedule and orders continue to convert, the company’s revenue and profit guidance could still be raised; however, investors should continue to monitor end demand, supply chains and inventory cycles, as well as substitution risks.

Risks

• Declining application investment supporting end-market demand, including AI/general-purpose servers, xEVs, and semiconductor manufacturing equipment.
• Weaker end-product demand caused by supply-chain disruptions or inventory adjustments.
• Emergence of substitution technologies that weaken the competitiveness of MARUWA’s existing products.
• If the accelerated start-up of new plants and buildings falls short of expectations, sales growth and earnings delivery could be affected.

What to watch

• Progress toward 3Q mass production and sales contribution at the Seto No.2 plant.
• Whether the Seto No.3 plant can begin production ahead of schedule and the pace of its FY3/28 start-up.
• Order conversion following the 4Q launch of CPO-related products and readiness for FY3/28 mass production.
• Capacity and sales ramp-up for semiconductor applications after the start-up of the two new Miharu plant buildings in 2Q.
• Whether margins improve from 2Q as management expects.
