TL;DR - SCK Company (Starbucks Korea, 2,115 stores) is expected to post an operating loss of ₩22.9 billion (~$15M) in Q2 2026, swinging from profit a year earlier, following the "Tank Day" boycott - Workers on July 18 formed South Korea's first-ever union at a coffee franchise; all 23,000 Starbucks Korea employees are directly hired, with no franchise buffer - Emart (139480.KS), which holds 67.5% of SCK, had its target price cut 14.8% to ₩115,000 by Korea Investment & Securities on July 10 - Starbucks Inc. holds a clause allowing it to repurchase Emart's stake at a 35% discount to appraised value if the licensing agreement is terminated for cause
Part A: From "Tank Day" to the First Picket Line
On July 18, 2026, baristas at Starbucks Korea took a step that 23,000 employees had never managed in 27 years of the chain's Korea operations: they formed a union.
The Korean Chemical, Textile and Food Workers' Union (KCTFU), affiliated with the Korean Confederation of Trade Unions (KCTU), announced the formation of a Starbucks Korea chapter — the first labor union at any coffee chain in South Korea.
The timing follows a damaging sequence of events. In May 2026, Starbucks Korea launched a promotion that social media users said evoked imagery from the military's deadly crackdown on pro-democracy protesters in Gwangju in 1980 — one of the most sensitive episodes in modern Korean history. The backlash was immediate. Shinsegae Group Chairman Chung Yong-jin issued a public apology, and stores temporarily closed nationwide for employee training on "historical awareness and social sensitivity." Customers staged organized boycotts.
The commercial fallout has been significant. SCK Company — the legal entity running Starbucks Korea, owned 67.5% by Emart (139480.KS) and 32.5% by Singapore sovereign wealth fund GIC — is expected to swing to an operating loss of ₩22.9 billion in Q2 2026, against a profit in the year-earlier period, according to Seoul Economic Daily. May and June sales declined as foot traffic fell.
SCK Company Key Financials
| Metric | FY2025 | YoY Change |
|---|---|---|
| Revenue | ₩3.24T (~$2.1B) | +4.4% |
| Operating Profit | ₩173B (~$114M) | -9.3% |
| Net Profit | ₩142.5B (~$94M) | -5.9% |
| Stores | 2,115 | — |
| Employees | ~23,000 | — |

FY2025 was already SCK's first earnings decline since 2022. Q2 2026 data now points to an accelerating downturn.
Workers say the crisis crystallized pre-existing grievances. The newly formed union cites: chronic understaffing; wages near the minimum wage level; scheduling that prevents secondary employment; and a growing stream of promotional campaigns — including the campaign that triggered the Tank Day backlash — that add workload without proportional pay. Workers had staged informal collective actions in 2021 and 2024 through anonymous online communities, including truck protests and funeral wreaths sent to headquarters, before formalizing in July 2026.
Part B: What Investors in Emart (139480.KS) Need to Watch
1. Direct Earnings Exposure
Emart consolidates SCK at 67.5%, meaning Starbucks Korea's operating results feed directly into Emart's consolidated income statement. Korea Investment & Securities on July 10 cut its Emart target 14.8% to ₩115,000, citing the Starbucks drag alongside stagnation at SSG.com, Emart's e-commerce arm. The sell-side consensus target stands around ₩123,000–₩130,000, implying meaningful upside from the mid-July ₩102,600 range, but conviction has declined since the Tank Day incident.
Emart faces an unusual structural constraint: SCK cannot pass labor costs down to franchisees because all 23,000 Starbucks Korea employees are directly employed by the company. Every ₩1 of wage increase from collective bargaining negotiations lands on SCK's income statement — and via Emart's 67.5% stake, on Emart's consolidated P&L.
2. Estimating the Union Wage Pressure
KCTU-affiliated unions in Korea's food-service sector typically open bargaining with demands of 10–15% above current compensation. If Starbucks Korea baristas earn at or near the 2026 minimum wage (₩10,030/hour), a 10% increase across approximately 23,000 employees at an estimated 30-hour average weekly schedule would add roughly ₩35–40 billion annually to the labor bill — equivalent to 20–23% of FY2025 operating profit. This estimate assumes no offsetting productivity changes or headcount reduction.
No strike has been announced. But the union's formation without prior management engagement — against the backdrop of the Tank Day apology and persistent foot-traffic weakness — gives workers unusual leverage entering first-round collective bargaining.
3. The License Risk Is a Tail but a Visible One
The most severe downside scenario relates to the Starbucks Inc. licensing structure. As reported by The Investor, if Starbucks Inc. determines that Emart bears liability for the Tank Day controversy sufficient to constitute a breach of the licensing agreement, it holds an option to repurchase Emart's 67.5% stake at a 35% discount to independently appraised valuation. Analysts estimate this discount clause could expose Emart to a write-down in the range of ₩500–640 billion — a significant sum relative to Emart's market capitalization.
This outcome is not the base case; it requires a formal finding of breach. But The Investor reported in June 2026 that Starbucks Inc. was evaluating strategic options for the Korea franchise, and the licensing risk has remained an overhang on Emart shares through H1 2026.
4. Broader Sector Implications
The KCTFU affiliation makes the Starbucks Korea union meaningful beyond one company. South Korea's coffee shop sector employs hundreds of thousands of workers across Twosome Place, Compose Coffee, Mega Coffee, and smaller chains. A successful first union at the category's premium-segment leader would set organizational and wage-benchmark precedents across the industry.
South Korea's labor landscape has been in motion since the Bank of Korea's July 16 rate hike to 2.75%, which raised household debt-service burdens and amplified workers' cost-of-living concerns — the same environment in which the Starbucks Korea union explicitly cited "wages insufficient to cover living expenses."
5. Recovery Catalysts Exist
Emart bulls point to: - Traffic repair measures: SCK paused its Summer Frequency loyalty program and issued 15 million complimentary drink coupons in June 2026 to rebuild customer visits — a direct comp-sales stimulus heading into H2 - Store count growth: SCK planned 100+ new openings in 2026, which would sustain revenue even under per-store sales pressure - Market position: At 2,115 locations, Starbucks Korea remains the category leader in Korea's premium coffee segment, with no near-term substitute at scale
A credible labor settlement and the Tank Day episode receding from public attention would likely restore sell-side confidence and support Emart's target-price recovery by Q4 2026.
