3 different insiders at Limbach Holdings, Inc. just bought LMB.

1. The cluster: 3 people, $515,920 between them in the last 30 days, each paying their own price separately.
2. The biggest buy: Joshua Horowitz (Director), 3,346 shares at $50.61 on 15 September 2026. That is the entry above -- a Form 4 discloses the price actually paid, so this is a real fill, not an estimate. It is what they paid on their own trade date, though, not a price available now.

Also buying: David Richard Gaboury (Director, $99,619), Laurel J Krzeminski (Director, $25,288).
3. Filed: 16 September 2026.

Risk: several different people buying is the whole signal -- one person buying repeatedly is one decision. Grants, option exercises and tax withholdings are excluded, since none of those is anybody choosing to put money in. An automated tracker of public SEC filings, not a recommendation.
