Shake Shack (Shake Shack (SHAK)) is having a rough Thursday. Shares are down about 28% after the company's first-quarter results came in a bit softer than Wall Street expected. The market is not in a forgiving mood when a growth story stumbles, even if the stumble is small.

Q1 By The Numbers

The burger chain reported first-quarter sales of $366.7 million, up 14.3% from a year ago but short of the $371.9 million analysts were looking for. That $5 million gap is enough to spook investors. Within that total, Shack sales contributed $354 million and licensing revenue added $12.7 million.

System-wide sales hit $558.3 million, up 14.1% year over year. Same-Shack sales — a key metric for restaurant chains — grew 4.6%, which is solid. Restaurant-level profit margins improved to 21.2% from 20.7% a year ago, so the core business is running efficiently.

The problem is on the bottom line. Adjusted EBITDA dropped to $37 million from $40.7 million a year ago, and the adjusted EBITDA margin shrank to 10.1% from 12.7%. That's a meaningful contraction, and it's likely what's weighing on the stock today.

Shake Shack opened 17 new company-operated Shacks and five licensed locations during the quarter. The company ended the period with $313.7 million in cash and equivalents, against $248 million in long-term debt.

"The strength of our pipeline and the compelling cash-on-cash returns provide the confidence to raise our full-year development guidance to 60-65 new Company-operated Shacks, up from our prior range of 55 to 60," the company said in a statement. That's a vote of confidence in the expansion strategy.

On the cost front, Shake Shack expects food and paper inflation to be in the low single digits for 2026, even with higher beef costs. Beef inflation is projected to stay at high single-digit levels, but supply chain initiatives should help offset some of that pressure.

Outlook

For the full year 2026, Shake Shack expects revenue between $1.6 billion and $1.7 billion, with restaurant-level profit margins of 23% to 23.5%. Adjusted EBITDA is forecast at $230 million to $245 million. For the second quarter, the company sees revenue of $424 million to $428 million.

New CFO On Board

In a separate announcement, Shake Shack named Michelle Hook as its new chief financial officer, effective May 11. Hook comes from Portillo's, where she served as CFO since 2020 and helped take the company public in 2021. Before that, she spent over 17 years at Domino's Pizza in various finance and investor relations roles.

CEO Rob Lynch said Hook's restaurant industry and public company experience will support Shake Shack's long-term expansion plans. It's a hire that signals the company is thinking about scaling up.

Technical Picture

The stock is trading well below its moving averages. The 20-day simple moving average is $100.11, and the stock is 24.2% below that level. The 50-day SMA is $94.80, with the stock 20% below it. That's a bearish setup.

The Relative Strength Index (RSI) sits at 48.47, which is neutral — not oversold, not overbought. That leaves room for more volatility.

MarketDash Edge Rankings

Here's how Shake Shack stacks up on key metrics compared to the broader market:

• Value Rank: 44.56 — The stock trades at a moderate premium to peers.
• Growth Rank: 86.51 — Strong growth potential relative to the market.
• Momentum Rank: 24.67 — The stock is underperforming the broader market.

The Verdict: Shake Shack's profile is mixed. Strong growth potential is there, but weak momentum and a value rank that's not screaming cheap suggest the market is waiting for proof that the expansion can translate into better profitability.

Shake Shack shares were down 28.38% at $69.13 at the time of publication on Thursday, hitting a new 52-week low.
