Summary
SL remains fundamentally an automotive supplier. The company generated KRW 5.24 trillion in 2025 revenue, with lamp-related products accounting for 78.2% of the total.
But its robotics exposure is becoming more tangible. SL has secured work across Hyundai Motor Group Robotics LAB’s MobED and Boston Dynamics platforms, moving from individual components into battery-pack assemblies, LiDAR modules, leg assemblies and robot production.
The potential scale is beginning to matter. Samsung Securities estimates that production of MobED and PluD could eventually generate KRW 250–400 billion in annual revenue for SL, equivalent to roughly 4.5–7% of projected 2026 sales. This is a brokerage estimate, not company guidance.
The investment question is therefore no longer whether SL has robotics exposure. It is whether the company can convert its automotive manufacturing capabilities into a meaningful second growth engine beyond auto parts.
Key Takeaways
- ✓ Automotive lamps remain SL’s core business, representing 78.2% of 2025 revenue.
- ✓ Robotics exposure is expanding from component supply toward modules and contract manufacturing, increasing the potential content value per robot.
- ✓ Samsung Securities estimates MobED and PluD could eventually contribute KRW 250–400 billion in annual revenue, but the estimate should not be treated as company guidance.
- ✓ Atlas remains an opportunity rather than a confirmed program, with SL participating in related bidding and product discussions.
- ✓ Using a KRW 50,600 reference price and FnGuide’s September 23 consensus, SL trades at approximately 6.4x 2026E P/E and 0.84x P/B, while the six-broker consensus target price stands at KRW 83,667.
What Happened
SL entered 2026 with a profitable core automotive business and an expanding robotics pipeline.
Second-quarter revenue reached KRW 1.37 trillion, up 5.6% year over year, while operating profit rose 18.8% to KRW 125.8 billion. Operating margin reached 9.2%. First-half revenue totaled approximately KRW 2.76 trillion and operating profit KRW 269.6 billion, implying a 9.8% operating margin.
The first-half margin should not be extrapolated mechanically. First-quarter earnings included one-off compensation related to the cancellation of a customer EV project, lifting reported profitability during the period.
At the same time, SL has been building a commercial position in robotics.
SL’s official sustainability report states that the company had already won Stretch indicator-lamp business and, in September 2024, secured MobED battery-pack assembly and LiDAR work together with OEM assembly and inspection. It also secured full leg assembly for Boston Dynamics’ Spot.
Samsung Securities later reported that SL had expanded its exposure to Hyundai Motor Group Robotics LAB’s PluD through battery-pack, LiDAR-module and contract-manufacturing work, while also participating in Atlas-related bidding. These later-stage opportunities remain subject to program schedules and customer decisions.
Why It Matters
The strategic significance is not simply that SL is supplying parts to robot makers.
It is that the company’s role is moving further down the manufacturing value chain.
A single component provides limited content per platform. Supplying integrated modules increases that content. Taking responsibility for robot assembly and production expands it again.
SL’s progression can therefore be viewed as:
Component → Module → Assembly / Production
For MobED, SL’s role already combines LiDAR-related equipment, battery-pack assembly and production responsibilities. Samsung Securities sees a similar structure developing around PluD.
That is why the brokerage’s KRW 250–400 billion revenue estimate matters. At roughly 4.5–7% of projected 2026 revenue, robotics would still be much smaller than the automotive business, but it would be large enough to begin affecting consolidated growth and revenue mix if realized.
More importantly, SL does not need to build a robotics business from zero.
Its existing competencies in high-volume manufacturing, module integration, electronics, sensing, battery systems and global automotive quality control can be applied to physical machines moving from development into mass production.
The economic opportunity is therefore not primarily robot intelligence.
It is robot industrialization.
SL should not yet be valued as a robotics company.
Robotics is commercially real, but its revenue and margins are still not separately disclosed.
The more important change is SL’s move from individual components toward modules and robot assembly.
A rerating requires visible robotics revenue, repeat program wins and evidence that those sales can generate attractive margins.
The opportunity is visible; the earnings proof is still ahead.
