Current Thesis

The post-Q2 advance kept going: the ADR closed $40.29 on 2026-08-21 after $38.51 on 2026-08-14 and $34.80 on the 2026-08-05 print session (+7.94% that day). RSI(14) reads 74.0 and the price sits 12.4% below the $46.00 52-week high, with a three-month price change of +7.4%.

The substantive change since the last note is not in the tape. The 2026-07-10 6-K said a follow-up disclosure on the KKR AI-data-center equity investment and the contemplated "capital increase of approximately Won 1 trillion" would come when determined "or within one month of the date of this report." The 2026-08-07 6-K reported no determinations and reset that commitment to "within three months of the date of this report." The ~2026-09-07 follow-up that a one-month cadence implied is therefore not company-committed; the outer bound is roughly 2026-11-07. The narrative leg an investor is buying — operating leverage from AI data-center (AIDC) scaling inside a shrinking Korean carrier — is intact in the reported numbers, but the dilution option attached to it is now unresolved and undated for the next month.

Bullish and bearish views on SK Telecom Co., Ltd.

The model's bull view on SK Telecom Co., Ltd. (SKM), in brief: Reported operating leverage: Q2 2026 operating income ₩566.0B, +67.3% YoY; net income ₩466.0B; revenue ₩4.3591T, +0.5% YoY (results release, 2026-08-05). The bear view: The mean target has been met: 017670 traded at ₩100,200 on 2026-08-21 against an average 12-month analyst target of ₩100,588 (high ₩150,000, low ₩55,000; 14 buy, 4 sell). Both cases follow in full.

Bull Case

• Reported operating leverage: Q2 2026 operating income ₩566.0B, +67.3% YoY; net income ₩466.0B; revenue ₩4.3591T, +0.5% YoY (results release, 2026-08-05).
• AIDC accelerated in percentage terms: ₩136.2B, +92.5% YoY in Q2 versus ₩131.4B, +89.3% YoY in Q1 (reported 2026-05-09).
• No forced issuance in the near window: the 2026-08-07 filing states no specific determinations have been made, which removes an imminent dilution print from the next 30 days even as it defers resolution.
• The estate has an outside price: reported talks to sell up to 49% of Ulsan for ₩2T — KKR 29%, IMM Investment and Stonebridge 20% — with 41MW available by November 2027 and 103MW by February 2029 under a 15-year AWS partnership; SK Group's allocation to the project is reported at roughly ₩7T with AWS contributing about $4B (DataCenterDynamics / Telecompaper, July 2026).
• A vehicle exists that can take partner capital without touching the parent's share count: SK Hyper, a wholly-owned AIDC subsidiary, board-approved with ₩750B planned through 2030 (2026-07-27).
• Capital return held through the capex ramp: ₩830/share declared for Q2 on 2026-08-05, unchanged from Q1.
• Capex has not yet run away on a YoY view: Q2 2026 capex ₩487B, −23.3% YoY (Q2 earnings presentation, 2026-08-05), though it stepped up +256.7% QoQ.
• Sell-side anchor above spot in local terms: JPMorgan's ₩110,000 target (Stanley Yang, upgrade to Overweight ~2026-07-16) against the ₩100,200 Seoul close of 2026-08-21.

Bear Case

• The mean target has been met: 017670 traded at ₩100,200 on 2026-08-21 against an average 12-month analyst target of ₩100,588 (high ₩150,000, low ₩55,000; 14 buy, 4 sell). Upside to consensus is effectively gone in the primary listing.
• The stake sale has been "near" for eight months: KED Global reported the process at up to $1.4B with KKR interested on 2025-12-15; reports of a share purchase agreement by end-June 2026 had not produced a confirmed signing as of the 2026-08-07 6-K.
• The clock got longer, not shorter: extending from one month to three months on 2026-08-07 means the market can wait until roughly 2026-11-07 — past the Q3 print — for the funding structure to be named.
• Issuance into strength remains the shape of the risk: a ~₩1T primary increase, if chosen, would be priced against a tape that has closed higher at every reference point since 2026-07-17 ($30.62 → $34.80 → $38.51 → $40.29).
• The operating income surge is not a revenue surge: revenue rose 0.5% YoY in Q2. INFERRED: with the top line flat, the +67.3% move is dominated by cost-base and comparison effects as year-ago USIM-breach remediation costs roll off, and AIDC at ₩136.2B is a small fraction of a ₩4.3591T quarterly base.
• The base business is contracting: FY2025 revenue −4.69% to ₩17.10T with earnings −68.41% to ₩388.61B.
• The June supply zone is untested: the $46.00 close of 2026-06-02, set after the +18.85% GTC-driven gap on 2026-06-01, has not been revisited.

Setup & Price Structure

• Reference sequence of closes: $30.62 (2026-07-17), $34.80 (2026-08-05), $38.51 (2026-08-14), $40.29 (2026-08-21). The last leg came without a named company disclosure in the window — the only filing between 2026-08-07 and 2026-08-21 on the record is a Schedule 13G/A dated 2026-08-13.
• Momentum is stretched on the standard measure: RSI(14) at 74.0 on the 2026-08-21 close, with price still 12.4% under the 52-week high.
• The narrative is maturing. The narrative is well known and still working, but the new-information flow has thinned. Dates that fix the label: the stake-sale story has been in trade press since 2025-12-15; the JPMorgan upgrade landed ~2026-07-16; the Q2 print on 2026-08-05 delivered the numbers; and on 2026-08-07 the one event that would expand participation — the funding determination — was pushed to a three-month outer window. Price is making higher closes into a consensus target that has already been reached.
• Crowding and positioning observables (stated as observables): RSI(14) 74.0; the Seoul line at ₩100,200 versus a ₩100,588 average target; a contemplated primary equity increase of approximately ₩1T that would, if executed, be sold into a tape well above its 2026-07-17 level; no company-committed disclosure date inside 30 days; the next earnings print estimated ~2026-11-05, so there is no imminent earnings gate to compress the move. The ADR also carries USD/KRW, so an ADR-only read mixes FX with fundamentals.

Catalyst Calendar (next 30 days)

• ~2026-08-26 (est.) — Nvidia fiscal Q2 results (historically the last week of August; not confirmed). SKM now trades with AI data-center capex sentiment, so a hyperscaler-capex scare reaches the name through the narrative channel even though AIDC is ₩136.2B of a ₩4.3591T quarterly top line.
• No company-committed SKM disclosure falls inside the window. The 2026-08-07 6-K sets the outer bound at roughly 2026-11-07; the earlier ~2026-09-07 expectation was an inference from a one-month cadence the company has since replaced.
• ~2026-11-05 (est.) — Q3 2026 results. Outside the 30-day window; re-marks AIDC YoY (+89.3% Q1, +92.5% Q2) and the capex path after the +256.7% QoQ step.

Elapsed catalysts

• Undated, could land any session — signing or collapse of the Ulsan 49% stake sale to the KKR/IMM/Stonebridge consortium. Reported as in final stages since mid-2026 without a confirmed agreement as of the 2026-08-07 6-K. (passed 19d ago)

What Would Change Our Mind

The funding structure is what settles this. A 6-K naming an issuance size and an offer price for a primary equity increase converts the overhang into a fact and resets the share count against a flat revenue line; a signed Ulsan agreement near the reported ₩2T does the opposite and removes it. Either filing is a bigger input than any of the price action since 2026-08-05.

On the tape, the thesis-break level is a weekly close below $34.80 — that hands back the entire 2026-08-05 print-session re-rating and returns the ADR to the range it traded before the Q2 numbers. Secondary conditions that would matter independently: the ~2026-11-07 outer deadline arriving with another "no specific determinations" filing, which would leave the AIDC funding question open into a third quarter and mark the theme saturated by attrition; AIDC revenue growth printing below roughly 50% YoY at Q3; a cut or suspension of the ₩830 quarterly dividend; or repeated failure to close above the mid-$40s on positive AIDC headlines, repeating the July pattern where the 15GW plan (2026-07-05) and the JPMorgan upgrade (~2026-07-16) both landed and the tape closed lower.

Correlation Notes

• Primary listing is Seoul 017670; the NYSE ADR adds USD/KRW. Weeks where 017670 closes higher in won while the ADR closes lower are FX, not fundamentals.
• AWS is the anchor partner at Ulsan under a reported 15-year arrangement, so Amazon's capex commentary is a more direct read-through than the general AI complex.
• SK Square holds roughly 20% of SK Hynix — group-level HBM/memory-cycle exposure that never appears on SKM's own P&L but colours how the group is priced.
• Domestic telco comps KT and LG Uplus share the Korean tariff and regulatory cycle; the AIDC premium is the variable that separates SKM from them.
• Anthropic's $100M strategic investment (2024-08-05) keeps the name over-weighted in Western AI-partnership screens relative to what AI contributes to revenue today.
