Shares of casual sandwich chain Potbelly (NASDAQ: PBPB) jumped 22.6% in the afternoon session after the company reported strong first quarter 2025 results which significantly beat analysts' EPS and EBITDA and sales estimates. System-wide sales grew nearly 5%, powered by an increase in shop openings and solid performance from both company-owned and franchise locations. Franchise development was a particular strength in the quarter. Potbelly opened four new shops and secured commitments for 40 more, laying a solid foundation for scalable, recurring growth. Zooming out, we think this quarter featured some important positives.
