Starbucks' Same-Store Sales Surge, But Margin Squeeze Clouds the Turnaround

What happened

Starbucks reported a strong Q2 with North America comparable sales up 7.1%, driven by a 4.4% transaction increase that the filing attributes primarily to higher delivery sales. However, North America operating margin fell to 10.0% from 11.6%, weighed down by ~260 bps of labor investments, product mix shift, and inflation. The stock has rallied strongly year-to-date as investors embrace the "turn in the turnaround" narrative, but the underlying profitability challenge remains unresolved. Meanwhile, the China business was restructured via a $3.1B JV with Boyu Capital, converting 7,991 company-operated stores to licensed economics, which will mechanically lower revenue and lift reported margins starting Q3. Despite the top-line momentum, the company still trades at 26.2x EV/EBITDA with net leverage of 4.3x, leaving limited room for error if transaction growth proves unsustainable without delivery tailwinds.

Implication

The headline strength in same-store sales masks a fragile profitability picture — operating margins are still compressing even as comps accelerate. The stock's 17% year-to-date rally has already priced in a sustained recovery, but the 10-Q reveals that labor investments and mix headwinds are consuming a large share of sales leverage. Investors should demand proof that transaction growth is broad-based and not delivery-dependent, and that North America margin can recover toward 11%+ in coming quarters. The China JV reset adds further opacity, as the deconsolidation will inflate reported margins but obscure underlying earnings power without a clear disclosure bridge. Given the elevated valuation and leverage, the risk-reward is unattractive until either margins inflect or the stock pulls back toward the $85 attractive entry zone.

Thesis delta

The thesis remains WAIT, as the Q2 results confirm both the demand recovery and the margin headwind. The market is pricing in the bull scenario (margin recovery) without sufficient evidence, while the 10-Q details underscore that the turnaround is still in its investment phase. No material change from the DeepValue assessment; near-term monitors are margin inflection and transaction sustainability.
