The whole Firehouse Subs filing, read.

FIREHOUSE OF AMERICA LLC's 2026 Franchise Disclosure Document, read for someone about to sign, with every figure cited to the page it came from.

Every fee. 27 rows for Firehouse Subs: initial, royalty, advertising, technology, transfer, renewal, audit, late, termination. The brand page shows the two headline rates; the report shows all of them.
Item 19, decoded. What the revenue figure measures, which units are in the sample and which were left out, and what it doesn't include.
Three years of units. Openings, terminations, non-renewals, reacquisitions, transfers, and whether the filing's own totals foot.
Every lawsuit, in plain words. Item 3 and Item 4, one line per matter.
Territory, renewal, transfer, termination. What is protected, what it costs to renew or sell, what they can terminate you for, and the non-compete.
The questions to ask existing franchisees that this filing's own numbers raise.
