| Squeeze measure | Latest reading | Investor read |
|---|---|---|
| Monday close | $16.60, gain of 20.20% | 3.5% over WSJ/FactSet consensus |
| Tuesday premarket | Trading at $18.13, up 9.22% | Shares have risen 31.3% since Friday close |
| Monday volume | 3.65 million shares traded | 4.1x 65-day average |
| June 15 short interest | 6.72 million shares short | 40.17% of the float |
| Next short-interest publication | July 10 | Will include June 30 settlement |
This is important for the stock, which has already pushed past most sell-side targets. WSJ/FactSet data had a Hold consensus, with 4 Buys and 14 Holds, a $15 median price target and a $16.04 average. The premarket quote Tuesday was trading roughly 13% above that average.
Jack in the Box is now in the Russell Microcap Index, FTSE Russell said, under consumer discretionary. The June 2026 Russell reconstitution kicked off at the U.S. open Monday.
| Russell Microcap lens | Number | JACK comparison |
|---|---|---|
| Russell Microcap median market cap | $291.9 mln | JACK’s $316.6 mln market cap is 8.5% higher |
| Russell Microcap high market cap | $1.1 bln | JACK is roughly 29% of that |
| JACK market cap | $316.6 mln | Works out to about $149,000 per system restaurant |
| JACK restaurant count | 2,128 | Spans 24 states, Guam, and Mexico |
The per-restaurant metric here is equity market value divided by total system units, not individual store price. That’s a big reason why even a known brand can have a microcap-like trade profile. After shares jumped Monday, Jack’s public equity value was still just above the Russell Microcap median.
Jack in the Box wrapped up the debt part of the trade last week, finishing a $500 million sale of Series 2026-1 7.624% fixed-rate senior secured notes. The company plans to use the cash to pay off its Series 2019-1 4.476% notes and part of its Series 2022-1 3.445% notes. Executive chairman and interim chief executive Mark King said the refinancing “cleared our near-term maturities” and pushed the next scheduled repayment out to 2029. investors.jackinthebox.com
| Capital item | Amount | Ratio to $316.6 mln market cap |
|---|---|---|
| Market cap in equity | $316.6 mln | 1.0x |
| Issued new fixed-rate notes | $500 mln | 1.6x |
| Class A-1 notes max capacity | up to $150 mln | 0.5x |
| Total fixed notes and class capacity | $650 mln | 2.1x |
The operating numbers are still weak. In May, the company posted a 3.8% drop in second-quarter same-store sales, restaurant-level margin slipped to 16.4% from 19.6%, and total revenue fell 4.3% to $254.3 million. “Second quarter results did not meet expectations,” King said then. The company said it will speed up its “JACK on Track” actions. investors.jackinthebox.com
The recent rally gives investors a bit of a price buffer as Jack works through debt and trims its store count. The company’s 2026 targets remain at 2,050 to 2,100 locations, with plans for about 20 new stores and 50 to 100 closures, mostly at franchised spots.
