Samsung Electronics: Labor Overhang – A Clearing Event

Core Conclusion

Samsung Electronics’ ongoing labor strike is a clearing event: the risk has been largely priced in through a 49ppt relative underperformance vs. SK hynix since April, while fundamental support from the AI-driven memory cycle, HBM market share recovery, and foundry optionality remains intact. Under our base case (70% probability), short-term disruption is limited; even a worst-case extended strike (20% probability) reduces 2026e EPS by only ~1% with no material impact on 2027-28. The stock offers an attractive entry point with 43% upside to our W381,000 price target.

Evidence Chain

1. The labor overhang is already discounted in the stock.
Since strike-related news intensified, Samsung has underperformed SK hynix by 49 percentage points (Exhibit 5 in the full report). The 18-day general strike (May 21–June 7) has affected wafer transfers in foundry but left memory operations relatively untouched. We view this relative underperformance as fully reflecting the uncertainty, making the stock a “clearing event” play where a resolution triggers sentiment reversal.

2. Fundamental earnings impact is contained even in adverse scenarios.

• Base case (70%): a short-duration agreement with a W40tr labor cost write-off (~9.5% of 2026e OP) allows quick normalization. Our updated EPS forecasts are W53,985 for 2026e, W74,381 for 2027e, and W74,499 for 2028e – revisions upward by 3%, 4%, 5% vs. prior estimates due to stronger 1Q26.
• Extended strike case (20%): if the impasse extends 2-3 weeks beyond the strike, downtime would reduce full-year DRAM/NAND supply by 2-4%, given Samsung’s ~36% DRAM and ~31% NAND market share. Implied 2026e EPS drops only ~1% to W51,909, while 2027-28e EPS remain largely unchanged (Exhibit 6).
  Thus, even the worst case does not derail the structural upcycle.

3. The valuation case is compelling on normalized earnings.
Our residual income model (cost of equity 11.5%, terminal growth 3%) yields a base-case target of W381,000 – implying 2.1x 2027e P/B (5x 2027e P/E), consistent with the stock’s commodity cycle peak multiple of 2.0x. The extended-strike scenario still gives W365,000 (37% upside). Structural improvements – long-term contracts (LTAs), renewed HBM leadership, and foundry optionality – should support a multiples re-rating beyond current levels.

Key Divergence and Risks

What the market may be missing:

• The “clearing” nature of the strike: once terms are agreed (likely aligning with SK hynix’s model of 10% profit sharing and no bonus cap), the overhang dissipates quickly, driving a valuation catch-up.
• The positive structural shift: LTAs smooth memory cyclicality, HBM market share recovery from 2026 (HBM bit growth revised down for 2026 but up for 2027 in our model) and foundry optionality are not yet reflected in multiples.

Risks to our thesis:

• Strike extends beyond the 18 days + 2-3 weeks, causing deeper production cuts than modeled (EPS impact >1%).
• Memory demand disappoints due to AI inference delays, macro slowdown, or Chinese competition.
• HBM share recovery proves slower than expected, capping margin expansion.
• Foundry losses widen or fail to achieve scale economies.

Valuation or Trade Implication

We recommend Overweight. Current price W266,000 offers 43% upside to our base target. Even under the extended-strike scenario, upside remains 37%. The risk/reward is attractive given the downside is limited by the strong cyclical earnings backdrop and the stock’s low valuation (2027e P/E of 4.0x). We incorporate a W40tr labor cost deduction in 2026 OP but see no permanent earnings damage. Preferred shares (005935.KS) are also rated Overweight with a target of W304,800 (20% discount to common, 2-year average).

Residual Income Model Sensitivity (Exhibit 3)
Base case: Target W381,000 (W2,514tn equity value / 6,607mn shares). Extended strike: W365,000. The model assumes ROE of 34.3% in FY27E, declining to 13.7% terminal.
