AI Chip Demand Lifts Miraial's Profit 52%, But a Marine-Instrument Buyout Adds Debt

Generative-AI datacenter demand pushed first-half net income at resin maker Miraial up 52% to ¥431mn, even as its April acquisition of a marine-instrument maker piled on ¥1.9bn of new borrowing and forced the company to introduce an adjusted-profit metric to smooth out the deal's goodwill and M&A costs.

Miraial, a Tokyo Stock Exchange-listed maker of high-function resin components mostly sold into the semiconductor supply chain, said first-half sales climbed 25.9% to ¥7.98bn and net income attributable to shareholders rose 52.0% to ¥431mn, as generative-AI datacenter investment kept lifting demand for advanced chip-handling parts through the six months to the end of July.

Adjusted operating profit excludes goodwill amortization and acquisition-related costs, a metric Miraial introduced this period; the prior-year figure shown equals reported operating profit before the new metric existed.
MetricFirst half to July 2025First half to July 2026Change
Net sales¥6.34bn¥7.98bn+25.9%
Operating profit¥334mn¥559mn+67.3%
Adjusted operating profit¥334mn¥640mn+91.7%
Net income attributable to owners¥283mn¥431mn+52.0%

The company's plastic-molding segment, which sells semiconductor-related products alongside fluid-system parts, electronic components and molds, reported segment sales of ¥7.36bn, up 29.7%, with segment operating profit rising 60.6% to ¥967mn. The smaller molding-machine business, whose order environment is shaped by the auto industry's slowing shift to EVs, grew a slower 1.5% to ¥774mn.

Miraial has started reporting a new headline figure, adjusted operating profit, that strips out goodwill amortization and acquisition-related costs; it rose 91.7% to ¥640mn, running ahead of the reported operating profit of ¥559mn, up 67.3%. The gap exists because Miraial bought a marine-navigation-instrument maker on April 30, 2026, along with two of its own subsidiaries, which became grandchild companies of Miraial and were consolidated for the first time this half. The purchase, worth about ¥1.91bn in cash, generated ¥826mn of goodwill that the company still calls provisional because it has not finished allocating the price to identifiable assets and liabilities. Miraial funded part of the deal with a new ¥1.9bn syndicated loan carrying covenants that require it to keep consolidated net assets at 75% or more of the higher of the prior fiscal year-end or the January 2026 fiscal year-end net-asset level, and avoid two consecutive years of an ordinary-income loss.

Two one-off items also ran through the half: a ¥41mn loss tied to the July 28 Kumamoto earthquake, which damaged inventory and idled production for a day and a half, and a ¥158mn gain from selling cross-held shares as part of a balance-sheet efficiency push. Separately, Miraial's board approved on June 1, 2026 the buyback of ¥499mn of its own shares and the cancellation of 1,010,000 treasury shares worth ¥1.57bn during the half, trimming capital surplus and retained earnings without changing total net worth. Total assets rose to ¥31.49bn and liabilities jumped to ¥9.02bn, largely reflecting the new subsidiaries and the loan, pushing the equity ratio down to 71.3% from 85.7%.

Management raised the interim dividend to ¥30 a share from ¥10 a year earlier but left the year-end payout undecided, and it declined to issue a full-year profit forecast, arguing that its semiconductor-exposed business swings too fast for a reliable annual estimate. Instead, it will keep disclosing results only one quarter at a time: the next checkpoint is cumulative nine-month sales of ¥13.05bn, adjusted operating profit of ¥1.28bn (operating profit ¥1.17bn) and net income of ¥850mn, all well above the prior year's nine-month figures but not a stand-in for a full annual guide. Company-wide sales to the semiconductor market rose to ¥6.97bn from ¥5.34bn, evidence that AI-linked chip investment is filtering down to component suppliers well outside the familiar chipmaking and equipment names.
