SPG has a real, profitable motor business and real precision-reducer production assets, but its disclosed numbers do not yet prove that robot reducers support a KRW 1.63 trillion equity value. At the November 6, 2026 KRX close of KRW 73,600, our present-value Bear/Base/Bull range is KRW 24,247 / KRW 63,518 / KRW 128,726 per share. The central uncertainty is not whether SPG can manufacture reducers; it is how much reducer and actuator revenue, margin and cash conversion the company can demonstrate separately from its established geared-motor business.
Prepared November 7, 2026 KST. This is our first Company Research baseline for SPG Co., Ltd. (KOSDAQ: 058610). Financial figures use consolidated K-IFRS unless stated otherwise; amounts are Korean won. The latest complete statutory financial filing available at the review date is the half-year report for the six months ended June 30, 2026. The third-quarter report is not yet due, so we do not treat an unfiled quarter as reported fact.
Three findings that matter
- The robotics option is tangible but not separately disclosed. SPG manufactures strain-wave, cycloidal and planetary reducers and integrated actuators, yet its filing does not isolate robot-reducer revenue, margin, orders or capacity utilization.
- Accounting profit improved while cash conversion weakened. H1 revenue fell 2.4% and operating profit rose 5.9%, but operating cash flow turned negative as inventory and receivables increased.
- The current price already requires a large 2029 earnings step-up. At our Base 28× 2029 EBITDA multiple and 12% margin, the November 6 price implies roughly KRW 659 billion of 2029 revenue—almost twice FY2025 revenue.
What SPG sells—and where the robot story begins
SPG began with small geared motors and still earns most of its disclosed revenue from motion components used in appliances and industrial automation. Its portfolio includes AC, DC and brushless DC motors; standard geared motors; controllers; planetary gearheads; KSH strain-wave reducers; KSR cycloidal reducers; and the company’s SDD integrated actuator. These products serve factory automation, semiconductor and display equipment, battery and logistics systems, appliances and robotic joints.
The established motor business matters because it provides manufacturing know-how, customer qualification experience and cash earnings while precision reducers scale. It also makes the investment case harder to read. In the parent-company H1 product table, “other” revenue was KRW 15.065 billion, or 13.2% of separate-company sales, but that bucket includes power motors, planetary and precision reducers, motion cameras and other items. Treating the entire amount as robot-reducer revenue would be false precision.
SPG’s July investor material lists Samsung Electronics, Hyundai Motor, Kia, Rainbow Robotics, LG CNS, LG Display, SEMES and other companies in its overall major-customer list. That list does not establish that each company buys precision reducers, how much it buys, or whether a named development relationship has reached revenue. The same caution applies to memoranda of understanding: collaboration can reduce technical and commercial uncertainty, but it is not an order, shipment or cash receipt.
The reducer ramp is real, but the economics remain opaque
| Company disclosure | Value | What it proves | What it does not prove |
|---|---|---|---|
| Precision-reducer revenue | KRW 7.6B in 2023; KRW 10.2B in 2024; KRW 14.0B 2025 estimate | Company-presented trajectory; 2023–2024 figures and a 2025 company estimate | 2026 revenue, margin, orders or cash collection |
| Annual capacity | Planetary about 100,000; strain-wave up to 150,000; cycloidal 10,000 | Installed production scope claimed by the company | Utilization, yield, qualified demand or unit economics |
| Precision-reducer equipment investment | KRW 27B | Meaningful manufacturing commitment | Cumulative period, return on capital or payback |
| SDD performance | 80.7% efficiency and 1.5% torque ripple in company comparison | Company test/simulation result | Independent certification or customer production economics |
The progression from KRW 7.6 billion to a KRW 14.0 billion estimate is useful evidence, but even the estimate would equal only about 4.1% of FY2025 consolidated revenue. A high valuation can still be justified if reducers and actuators compound rapidly at attractive margins. The missing bridge is disclosed 2026 revenue, orders converted to shipments, utilization of the added machines, segment margin and cash collection.
The company’s latest investor deck describes supplier registration and overseas supply-chain expansion through POSCO International’s network. We treat this as a route to possible business, not as an achieved customer order. The next evidence should move in sequence: registration, binding order, shipment, recognized revenue, margin and cash. Skipping steps converts a business-development plan into assumed earnings.
H1 2026: lower revenue, better margin
| Consolidated metric | H1 2026 | H1 2025 | Change |
|---|---|---|---|
| Revenue | KRW 169.602B | KRW 173.762B | −2.4% |
| Gross profit | KRW 30.720B | KRW 31.115B | −1.3% |
| Operating profit | KRW 8.483B | KRW 8.010B | +5.9% |
| Operating margin | 5.00% | 4.61% | +0.39 ppt |
| Net income | KRW 5.899B | KRW 5.526B | +6.8% |
| Basic EPS | KRW 266 | KRW 249 | +6.8% |
H1 shows cost and mix improvement rather than top-line acceleration. Revenue declined, while operating margin rose by 39 basis points. Q2 alone was stronger than Q1: revenue was KRW 88.770 billion, operating profit KRW 3.997 billion and net income KRW 2.435 billion. Compared with Q2 2025, revenue increased about 10.3%, but operating profit rose only about 2.0%. One quarter is insufficient to establish a new margin trend.
FY2025 revenue was KRW 341.670 billion and operating profit KRW 17.939 billion, versus KRW 388.477 billion and KRW 12.335 billion in FY2024. The two-year picture therefore combines a large 2025 revenue decline with better profitability. A reducer-led reacceleration must be demonstrated in reported sales, not inferred from product announcements.
Exports diversify demand—and add currency and regional exposure
| H1 2026 geography | Revenue | Share of consolidated revenue |
|---|---|---|
| South Korea | KRW 47.953B | 28.3% |
| United States | KRW 51.809B | 30.5% |
| China | KRW 51.400B | 30.3% |
| Europe | KRW 9.029B | 5.3% |
| Japan | KRW 4.333B | 2.6% |
| Other overseas | KRW 5.078B | 3.0% |
The export mix gives SPG a broader addressable market than a domestic-only supplier, but it also exposes earnings to appliance demand, industrial cycles, foreign exchange and Chinese competition. The filing does not provide a customer-concentration table that lets us verify whether any individual customer exceeded 10% of H1 consolidated revenue. We therefore do not infer concentration from the company’s customer-logo list.
Working capital is the immediate financial test
| June 30, 2026 item | Value | Change from FY2025 |
|---|---|---|
| Cash and equivalents | KRW 38.840B | −KRW 3.184B |
| Short-term financial assets | KRW 5.005B | +KRW 0.802B |
| Trade receivables, net | KRW 110.669B | +11.1% |
| Inventory | KRW 159.579B | +14.3% |
| Borrowings plus leases | KRW 74.096B | Higher |
| Net debt including leases | KRW 30.252B | AHNIM calculation |
Operating cash flow was negative KRW 3.495 billion in H1 2026, compared with positive KRW 6.131 billion a year earlier. Subtracting KRW 3.421 billion of tangible capex and KRW 0.204 billion of intangible purchases produces our simple negative KRW 7.121 billion free-cash-flow measure. It is not a company-defined metric. The main pressure was a KRW 14.368 billion working-capital outflow, including inventory and receivable increases.
The receivable detail requires attention. Contractually overdue trade and other receivables increased to KRW 32.391 billion from KRW 2.744 billion at FY2025, while the allowance was KRW 4.967 billion. Overdue does not automatically mean uncollectible, but the change is too large to dismiss. A genuine robotics ramp should eventually improve revenue and cash; if inventory and receivables keep absorbing cash, reported profit will be a weaker indicator of shareholder value.
Dilution is not the current problem. The filing shows 22,177,360 common shares, no treasury shares, no preferred stock, no outstanding convertible or warrant bonds and no unexercised stock options at the half-year date. The articles permit future financing instruments, but authorization is not outstanding dilution and is not included in our share count.
AHNIM valuation: what the robot option must earn
We value SPG with a 2029 enterprise-value-to-EBITDA framework because the current thesis depends on a multi-year reducer and actuator ramp. Formula: 2029 revenue × EBITDA margin × terminal EV/EBITDA multiple, discounted three years at 10%, less June 2026 net debt including leases, divided by 22.177 million shares. We hold that current net-debt amount constant rather than forecasting a separate 2029 balance. These are AHNIM assumptions, not company guidance or analyst estimates. The high multiples deliberately give credit to successful robotics growth; they are not measured peer medians.
| AHNIM scenario | 2029 revenue | EBITDA margin | EV/EBITDA | Present value/share |
|---|---|---|---|---|
| Bear | KRW 420B | 9% | 20× | KRW 24,247 |
| Base | KRW 570B | 12% | 28× | KRW 63,518 |
| Bull | KRW 800B | 15% | 32× | KRW 128,726 |
Bear assumes moderate revenue growth and limited reducer economics. Base requires 2029 revenue 66.8% above FY2025, a 12% EBITDA margin and a premium 28× terminal multiple. Bull requires revenue more than double FY2025, a 15% margin and a 32× multiple. It is a successful global robotics-supplier outcome, not a default extrapolation of current disclosures.
The November 6 KRX close of KRW 73,600 multiplied by reported shares gives a reproducible KRW 1.632 trillion market capitalization. To support that price under the Base 28× multiple and 12% margin, the model needs about KRW 79.0 billion of 2029 EBITDA and KRW 658.6 billion of 2029 revenue. That implied revenue is approximately 1.93× FY2025 revenue. The current price is 15.9% above our unrounded Base present value.
Broker targets are materially above our Base
Mirae Asset Securities initiated Buy with a KRW 129,000 target on August 21. Secondary reporting says iM Securities maintained Buy and KRW 160,000 on August 19; IBK initiated Buy and KRW 100,000 on July 20. A secondary tracker’s recent-three-month sample contained two brokers—Mirae and iM—and averaged KRW 144,500 as of November 5; the July 20 IBK report had aged outside that window. We reviewed the Mirae report page, but not the complete iM or IBK research models, so we do not invent the assumptions behind them.
Our unrounded KRW 63,518 Base is 56.0% below the KRW 144,500 two-report reference average, triggering AHNIM’s 20% divergence flag. The comparison is imperfect: broker targets may capitalize distant robotics earnings differently, while our model discounts a 2029 terminal value and retains current net debt. We would raise our Base only when disclosed reducer and actuator revenue, binding orders converted into sales, capacity utilization, segment margin and cash collection justify higher revenue or margin assumptions. A lower discount rate or higher terminal multiple would also lift value, but it would not create operating evidence.
What would change the thesis?
- Stronger: separately disclosed precision-reducer and actuator revenue, orders that reach shipment and cash, rising utilization, stable or improving unit margin, and receivables growing no faster than sales.
- Weaker: qualifications and MOUs that do not convert, inventory continuing to outgrow revenue, overdue receivables remaining elevated, or new capacity requiring financing before cash conversion improves.
- Next filing checks: Q3 product and geography disclosures, inventory, overdue receivables, operating cash flow, debt, and any quantified reducer or SDD order/revenue update.
Current conclusion: SPG deserves attention as a Korean motion-control manufacturer with a credible path into robot joints. The market already prices much more than the existing disclosed reducer economics. Our Base case requires substantial growth and a premium terminal multiple, yet still sits below the November 6 close. The next valuation upgrade should come from segment economics and cash conversion—not from another customer logo, capacity number or memorandum.
