The CFO's open-market purchase alongside two directors within days of a mixed earnings report is a strong conviction signal. Monitor for additional insider filings in the next 2 weeks — if more C-suite buys emerge, it would reinforce the bullish thesis. The raised revenue guidance ($880-900M) provides a catalyst timeline through year-end, but margin trajectory remains the key risk to watch on the next 10-Q.
Price Chart
Executive Summary

Key Financial Metrics
Key Facts
- Three insiders (CFO + 2 directors) purchased $1.21M in open-market shares over 7 days
- Purchases occurred 6 days after Q2 2026 earnings: record revenue $226.9M (+114% YoY) but adjusted EBITDA margin fell to 12.4% from 18.6%
- Total insider buying of $1.21M represents ~0.06% of $1.9B market cap, below the 0.1% materiality threshold but amplified by cluster dynamics
- CFO Rowe Michael Bruce Jr. purchased $256K at $36.53 — a C-suite open-market buy carries strong signal weight
Financial Impact
Insider cluster of $1.21M in open-market purchases, ~0.06% of market cap, but amplified by C-suite participation and post-earnings timing
Risk Factors
- Adjusted EBITDA margin collapsed to 12.4% from 18.6% YoY, with guidance lowered to 16-18% from 20%+
- Insider buying at 0.06% of market cap is below the 0.1% materiality threshold on a standalone basis
- Q2 margin compression from one-time subcontractor costs and weather disruptions may persist into H2
