Share is lost in a segment, not in a market. The first job is to name which customers left and why they were winnable.
A competitor taking customers is a win-rate and loss-reason problem, not a brand problem. If losses concentrate in one segment, one price band, or one product, the response is specific. If losses are even, you have a broader offer problem. Discounting to win them back converts a share problem into a margin problem and teaches the remaining book that price is negotiable.
The move that usually makes it worse: Matching the competitor on price across the whole book, which trains your best customers to wait for the next cut.
Percision is the wrong tool if you already know the answer and only need execution capacity, or if the business is pre-revenue — then the constraint is evidence about the market, not analysis of your own figures.

Strategy School lesson: competitor-undercutting
Only in the segment where you are actually losing and only if your cost to serve supports it. A book-wide match is how a competitor's promotion becomes your new list price.
Read the loss reasons by segment. If the same competitor wins on price in one band and on product in another, those are two problems and one deck will not fix both.
