NATIONAL INDUSTRIES FOR THE BLIND

National Industries for the Blind triggered four detectors. Benford's law analysis of leading digits in 252 award amounts showed no significant anomaly, with a p-value of 0.356. Modification growth on contract HQ003421D0011 was extreme: the parent award's modifications grew at a ratio of 957.66, roughly 25 times faster than the median ratio of 38.35 for peers in the same NAICS code, yielding a z-score of 7.74. Isolation Forest flagged the entity as a multivariate outlier with a score of 0.875, driven by its high modification frequency and concentration of awards among few agencies. Sole-source concentration was also elevated: 246 of 252 awards were sole-source, placing the entity 2.54 standard deviations above the median of zero for its 30-entity peer group.

The entity holds 271.9 million dollars across 252 lifetime awards, averaging 1.08 million per award. The worst-performing contract shows modifications totaling 957 times the initial award value. The isolation anomaly reflects a feature vector with log total dollars of 8.43, awards concentrated among only two agencies, and 37.7 percent of awards modified. Sole-source awards comprise 97.6 percent of the portfolio versus a peer median of zero percent.

These signals warrant scrutiny but require context. National Industries for the Blind is a congressionally chartered nonprofit employing blind workers, which may legitimately justify sole-source awards under federal procurement law. The modification growth spike on a single contract deserves investigation but could reflect legitimate scope changes on a large production contract. The small peer group of 30 entities in cut-and-sew apparel contracting may not capture comparable business models. The entity's 271-million-dollar lifetime portfolio and 252-award history suggest an established contractor rather than a fly-by-night operator.
