Nippon Gear sells valve actuators, then services them for up to 50 years
Nippon Gear’s best-known product is a valve actuator: an electric motor and gearbox mounted on an industrial valve. The actuator supplies the force that opens, closes or positions the valve when a control system sends a command. If the actuator fails, the plant can lose remote or automatic control of the steam, fuel, chemicals or water passing through that line.
The company also makes jacks, speed reducers and custom gears for equipment that must move accurately under demanding loads and operating conditions. Together, these products generated ¥7.51 billion of revenue and ¥1.69 billion of OP in FY03/26.
Nippon Gear then earns a second stream of revenue from equipment already in the field. Its service segment inspects, diagnoses, repairs and modifies gear devices and other products the company previously sold. In FY03/26, service generated ¥2.37 billion of revenue and ¥771 million of OP.03
The figures show the business plainly: products provide most of the revenue, while maintenance of previously sold equipment contributes almost one-third of company OP at a 32.5% margin. At the August 21 close of ¥1,299, the operating business was valued at 4.69x FY03/27 guided OP after subtracting net cash.
Profit and cash changed faster than revenue
Revenue rose from ¥7.57 billion to ¥9.88 billion between FY03/22 and FY03/26. Over the same period, group OP rose from ¥0.12 billion to ¥2.46 billion and net cash more than doubled to ¥6.05 billion. Shares ex treasury remained at about 14.24 million.07151617

Margins improved before nuclear policy drove the shares to ¥2,200
Earnings started the re-rating. Expectations of U.S. nuclear projects then pushed the shares far beyond the value of any disclosed Nippon Gear order.
The shares still priced Nippon Gear as a low-return machinery maker.
Product economics had improved enough for the market to change its view.
Reports of nuclear projects in the next U.S.-investment package ignited the theme.
Forty-one percent below the peak close, yet 143.3% above two years earlier.
Nippon Gear closed at ¥534 on July 31, 2024. The shares remained below ¥500 through much of the following year even as the product business became steadily more profitable. Recognition began during FY03/26. The stock was ¥466 when Nippon Gear released its FY03/25 results on May 13, 2025. By July 31 it had reached ¥629, and it closed at ¥850 when the FY03/26 first-half result was released on October 31.
The next move came from nuclear policy rather than company earnings. At 10:21 a.m. on February 19, Minkabu Press reported that Japan was considering nuclear plants and next-generation reactors for the second U.S.-investment package and wrote that Nippon Gear was bid limit-up.11 The shares closed at ¥1,092 that day, up 15.9%, rose another 22.4% to ¥1,337 on February 20 and reached a peak close of ¥2,200 on March 9.
On March 19, Japan and the United States confirmed up to $40 billion of small-modular-reactor projects in Tennessee and Alabama.12 The investment package gave investors a concrete reason to expect more demand for the valve actuators used in nuclear plants. Nippon Gear’s shares subsequently fell to a post-peak closing low of ¥1,177 on April 7.
Company earnings remained strong. FY03/26 OP reached ¥2.46 billion, up 16.7% YoY. FY03/27 first-quarter orders rose 12.1% YoY, and backlog reached ¥7.50 billion at June 30.04 At ¥1,299, the stock retains the earnings re-rating from ¥534 but has shed most of the premium attached to the ¥2,200 nuclear-policy peak. The next re-rating now depends on product margin remaining near 20% and management putting ¥6.77 billion of net cash to work.
One actuator can generate scheduled service work for 30 to 50 years
Nippon Gear sells the actuator once, then returns for inspections, diagnostics, parts, overhauls and modifications throughout its operating life.
Nippon Gear says its products normally last 10 to 20 years and can remain in use for 30 to 50 years with continued maintenance.01 That long life creates recurring work because the actuator’s gears, bearings, stem nut, seals, lubricant and electrical components wear at different rates.
The company gives customers a defined inspection cycle. A Level A inspection is performed on site every year. Level B work is performed on site every three to five years and includes removing the motor to inspect gears and electrical parts. Every seven to ten years, a Level C inspection brings the actuator back to Nippon Gear’s factory for a complete overhaul, replacement of worn parts and performance testing.02
Nippon Gear also sells diagnostic services between overhauls. MAC measures torque while a motor-operated valve moves and identifies problems in the drive train or valve. eMAC uses an initial torque measurement as a baseline, then checks motor current from the control center to track deterioration at lower cost. MOVDAS uses a built-in torque sensor and waveform analysis to monitor wear and abnormal operation while the valve remains in service.02
More than 300,000 electric actuators have been produced, and Nippon Gear supports them with service offices, maker parts, repair procedures and factory testing. Each installed unit can therefore produce a sequence of annual checks, periodic detailed inspections, replacement parts, repairs and eventual modifications. FY03/26 service revenue of ¥2.37 billion and OP of ¥771 million show that this installed-base work already contributes materially to earnings.
Has the product business reset above a 20% margin?
Service was already profitable. The large change in Nippon Gear’s earnings came from the product segment.
Product OP margin rose from 1.2% in FY03/22 to 11.3% in FY03/23, 17.4% in FY03/24, 17.9% in FY03/25 and 22.4% in FY03/26. Product OP increased by ¥393 million in FY03/26, while service OP declined by ¥43 million. Products therefore supplied the entire increase in company OP.0317
The group income statement shows the same improvement. FY03/26 revenue rose 3.4% YoY while cost of sales fell 4.0% YoY. Gross margin increased 4.0ppt from 44.6% to 48.6%, and OP rose 16.7% YoY. Nippon Gear earned more from each yen of revenue rather than relying on volume alone.
Management’s May 2024 plan set company-wide cumulative targets for FY03/25–FY03/27. If FY03/27 guidance is achieved, the three-year total will reach 98.1% of the revenue target, 117.7% of the OP target and 126.5% of the net-income target.05 The improvement in profit has already run well ahead of the original plan.
FY03/27 first-quarter product OP margin was 22.6%. Valve-actuator orders rose 16.6% YoY, and total backlog increased 31.5% from March to ¥7.50 billion. Backlog now equals 75% of full-year sales guidance.
Headline company OP rose ¥117 million YoY in the quarter. A favorable ¥75 million swing in pension accounting supplied roughly two-thirds of that increase.04 The cleaner operating measure is therefore the product-segment margin itself.
The next result should show whether the ¥7.50 billion backlog can move through production while product OP margin remains around 20%. Holding that level would confirm that the five-year improvement has become the normal earnings base.
Will management return surplus capital or keep accumulating it?
Nippon Gear had ¥6.83 billion of cash and only ¥63 million of interest-bearing debt at June 30, 2026. Net cash was ¥6.77 billion, equal to 36.6% of the company’s ¥18.49 billion market capitalization. The company also held ¥1.77 billion of investment securities.04
Nippon Gear is funding product development, equipment replacement and a new heat-treatment facility. The largest disclosed project is ¥1.48 billion of seismic work at the Fujisawa factory, scheduled for completion after December 2027.08 That project equals about 22% of current net cash and will be paid over several years. Meanwhile, the business generated ¥1.79 billion of FCF in FY03/26 after spending on tangible and intangible assets.
Shareholders received ¥10 per share, an 8.1% payout, and Nippon Gear has no active buyback. The company also held ¥1.77 billion of investment securities, including 19 listed cross-shareholdings with an FY03/26 book value of ¥1.48 billion. Cash and securities are therefore likely to keep growing unless management changes its return policy.
The controlling shareholder is Seiwa Co., Ltd., a Tokyo-based industrial-valve distributor that also sells Nippon Gear actuators, jacks and gears.14 Seiwa holds 39.69% of voting rights. Nippon Gear President Haruo Terada13 is also a Seiwa director, and Nippon Gear sold ¥1.23 billion of products through Seiwa in FY03/26.06
Capital allocation therefore depends on a controlling shareholder that is also a commercial counterparty. A stated cash ceiling, a higher payout, a buyback or a timetable for reducing listed cross-shareholdings would convert surplus capital into a measurable benefit for minority shareholders. If management continues to retain the cash, investors are likely to keep valuing the operating business at a discount.
Subtracting ¥475 of net cash leaves ¥824 per share for the operating business
At a 20% product margin, the operating business is valued at 5.10x group OP. At 22.6% the multiple is 4.69x; at 15%, 6.11x.
| Product OP margin | Normalized group OP | Group OP per share | EV / OP at ¥1,299 |
|---|---|---|---|
| 15.0% | ¥1.92bn | ¥135 | 6.11x |
| 20.0% | ¥2.30bn | ¥162 | 5.10x |
| 22.6% | ¥2.50bn | ¥176 | 4.69xFY03/27 Q1 margin |
Net cash per share is ¥6.77 billion ÷ 14.237 million shares = ¥475. The table subtracts ¥475 from the ¥1,299 close, then divides the remaining ¥824 by normalized OP per share.
At the August 21 close, each Nippon Gear share cost ¥1,299. At June 30, the company had ¥6.77 billion of net cash, equal to ¥475 per share. Subtracting the cash leaves ¥824 per share for the operating business. Across 14.237 million shares, that is an EV of ¥11.73 billion.
How much OP does that ¥824 buy? Using FY03/27 revenue guidance, the FY03/26 segment mix and the 32.5% service margin, a 15% product margin produces ¥1.92 billion of group OP, or ¥135 per share. A 20% product margin produces ¥2.30 billion, or ¥162 per share. Holding the first-quarter product margin of 22.6% produces the company’s ¥2.50 billion guidance, or ¥176 per share.
At the current price, those three earnings outcomes correspond to EV/OP multiples of 6.11x, 5.10x and 4.69x. The stock therefore remains near 5x normalized OP if product margin settles at 20%. The multiple rises above 6x once product margin falls below roughly 15.5%.
The ¥824 operating-business price deducts the full ¥475 per share of net cash. Investors may still value that cash below face value if management leaves it idle. Nippon Gear currently pays out 8.1% of profit and has no active buyback. A stated cash ceiling, higher payout or buyback would give shareholders a clearer route to the cash and reduce the reason for a discount.
What to watch in future disclosure
A breakdown of inspections, diagnostics, parts, repair and modification, together with the active installed base, would clarify the scale of recurring revenue.
The contributions from price, mix, procurement, productivity and pension effects would help investors judge whether the margin can persist.
A stated operating cash requirement and policy for using the remainder on dividends, buybacks and cross-holding reductions would clarify the value of surplus capital.
