PWR — what changed in the latest 10-Q

A section-by-section comparison of PWR's newest periodic SEC filing (10-K/10-Q) against the prior same-form filing: paragraphs added and removed per section, with verbatim excerpts. Purely a deterministic text diff — no similarity scores, no directional read, not investment advice.

How to read Risk Factors (Item 1A) in a 10-Q

A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:

  • Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
  • Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
  • Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.

This describes the filing structure only — it is never a judgement on whether risk went up or down.
