The adjacent values separate the outliers from the rest of the data. They are the 25th or 75th percentiles plus 1.5 times the Inter-Quartlile range, which is the distance between the 25th and 75th percentiles. However, the adjacent value indicated on the graph, by convention, is "rolled back" to an actual data point, so that there is always real data underneath the adjacent value.

So the adjacent values are not actually percentiles....but "adjust" to the characteristics of the data.
