Taco Bell sales fell 4% after its lettuce outbreak, but Yum says customers are coming back

Yum Brands reported third-quarter earnings on Tuesday that beat Wall Street expectations, but the quarter carried a visible scar. According to CNBC, a cyclospora outbreak linked to iceberg lettuce at Taco Bell pushed the chain\'s same-store sales down 4% as diners temporarily stayed away. The Wall Street Journal frames it the same way: revenue rose despite the outbreak fallout.

The numbers

• Net income was $1.62 billion, or $5.92 a share, against $397 million a year earlier. That jump includes gains from selling Pizza Hut. Excluding those and other items, Yum earned $1.56 a share (CNBC).
• Excluding Pizza Hut, Yum\'s same-store sales were flat for the quarter. Taco Bell\'s fell 4%.
• Taco Bell\'s smaller international business grew same-store sales 5%. KFC\'s same-store sales rose 1%, while KFC U.S. system sales shrank 6%.

Yum closed the sale of Pizza Hut\'s mainland China business to Yum China on August 7 and sold the rest of Pizza Hut to LongRange Capital on September 1, so third-quarter results include Pizza Hut only until those dates.

How fast customers came back

This is the part a restaurant owner should read closely. Yum executives said the weekend of July 18 was the worst for sales, and trends have improved since. On the earnings call, CFO Ranjith Roy said Taco Bell\'s same-store sales are up about 1% so far in the fourth quarter, and up 3% over the four weeks ended Friday. CEO Chris Turner said Taco Bell U.S. has outpaced the quick-service industry since the end of September.

The recovery was uneven by customer type, per CNBC\'s account of the call:

• Heavy users: visits are back to normal.
• Medium and light users: visits are about 95% of prior levels.

Yum credited weekly Tuesday deals for loyalty members for pulling its most loyal customers back faster, and a pink Mountain Dew Baja Blast tie-in with Olivia Rodrigo for reaching casual diners. In plain terms: the regulars forgave quickly, and the occasional customer is the one still being won back, roughly three months on.

What it means for an independent restaurant

Taco Bell has a loyalty program, national advertising and a company with the resources to run promotions for months. A single-location owner does not. The lesson from the call is about the customers who matter most: the repeat base returned fastest, which argues for knowing who your regulars are and reaching them directly before a problem hits. The Chronicle\'s data shows how crowded that field is: we hold records for 605,380 independent restaurants in the U.S. (chains excluded), and each of them competes for the same occasional diner Taco Bell is trying to win back.

What we could not confirm

Yum\'s call comments are the company\'s own account of its recovery; we have not independently verified the traffic percentages. For the outbreak itself, including current case counts, use the CDC outbreak page and the FDA, which first linked the illnesses to iceberg lettuce served at Taco Bell. Counts have been reported differently as states update, so we are not repeating a figure here.
