Morgan Stanley has established a price target of ¥56,314 for Mitsui Kinzoku (TSE:5706), basing that figure on a fiscal year 2028 earnings-per-share forecast of ¥1,942 and an overall price-to-earnings multiple of 29.0 times.
The brokerage used a sum-of-the-parts framework to arrive at its valuation, assigning a 36.5 times P/E multiple to the company’s copper foil operations while applying a 15.5 times multiple to its other businesses. Taken together, those multiples produce an overall valuation that corresponds to an implied price-to-book ratio of roughly 5.5 times.
Morgan Stanley pointed to recent trade data as supportive of the copper foil thesis. In May, Malaysia’s copper foil export value rose 91% year-over-year. The bank noted that shipments to Taiwan remained at record high levels, a pattern Morgan Stanley attributed primarily to copper clad laminate production that uses Mitsui Kinzoku’s copper foil.
Looking at combined copper foil and copper clad laminate exports out of Malaysia to China, Hong Kong, Taiwan and Japan, Morgan Stanley reported a 91% increase year-over-year in May, while month-over-month shipments fell 2% for the same period. Regional detail provided by the firm showed:
- China: exports up 40% year-over-year and up 2% month-over-month in May.
- Taiwan: exports up 184% year-over-year but down 25% month-over-month in May.
- Japan: exports up 95% year-over-year and up 77% month-over-month in May.
Separately, Japan’s copper foil export volume reached 4,248 tons in May, which represented a 9% decline from the prior month but a 6% increase compared with the same month a year earlier. The export value from Japan totaled ¥28.2 billion in May, down 9% month-over-month but up 46% year-over-year.
Morgan Stanley also flagged broader commodity market moves: LME copper prices rose 42% on a year-over-year basis. The bank highlighted specific product lines from Mitsui Kinzoku - MicroThin and VSP copper foil - as contributors to earnings growth, noting their application in AI server markets.
The valuation approach and the trade flow data together form the basis for Morgan Stanley’s outlook for Mitsui Kinzoku, with the copper foil segment carrying a substantially higher earnings multiple than the firm's other operations.
