Thesis: fraud, analyst: snowcap-research, sector: construction.
We are short Sterling Infrastructure (NASDAQ:STRL), a poster child for the AI bubble. Data center exposure appears exaggerated. Backlog growth is not supported by contract win data. Margins appear grossly inflated through abnormal accounting revisions. We see 60-80% downside.

Sterling Infrastructure (NASDAQ:STRL) - Snowcap Research short thesis, Feb 2026.
Key Points:
Not really a data center company. Sterling owns regional contractors specializing in site preparation and excavation services. Despite claiming data centers drive a "step change improvement" in gross margins, Snowcap's review of hundreds of projects found just 18 data center projects since 2020 - far below the "100 or so" implied by management.
Data center exposure exaggerated. The second largest subsidiary (Petillo) appears to have completed just ONE data center project since acquisition in 2021. Recently published data indicates 40% of E-Infrastructure revenues are from generic warehouses (lower-margin), contradicting management's claim that the "vast majority" are mission critical.
Backlog growth suspicious. Sterling claims 40% CAGR backlog growth, but self-reported data to ENR shows new contract wins at flagship subsidiaries are in decline. ~75% of claimed backlog growth since 2021 is unexplained.
Margins implausibly high. If half of e-infra revenues are lower-margin warehouse work (~15% gross margins), the implied data center margins would be 45%+. Competitors say 30% is best-case and express skepticism over durability.
Abnormal accounting revisions driving margins. ~7% of revenues are from "changes to contract estimates" - accounting assumptions flagged by the auditor as a key uncertainty area. These revisions drove 45-48% of FY24 EBIT and 9M25 EBIT. The revisions are way out of sync with peers and represent a substantial uptick from previous periods.
CFO instability. Two CFO departures since May 2024, with the most recent lasting less than a year.
Cash flow misleading. Propped up by one-time benefit from advanced billings. Strip these out and cash conversion collapses to just 40% in 9M25.
Valuation extreme. E-Infrastructure business trading at ~29x NTM EV/EBITDA - a premium to NVIDIA and on par with Vertiv (pure-play data center infrastructure with vastly superior growth).
Downside: 60% downside even if margins are sustainable. Further downside if margins normalize to industry peers. Snowcap sees 60-80% downside.
