Struggling to write clean, audit-ready price–volume–mix commentary for your model bridges? This lesson gives you precise, repeatable phrasing to attribute revenue, margin, and EPS movements—separating PVM from FX, M&A, calendar, and one-offs with disciplined units and sign conventions. You’ll find a tight core explainer, reusable sentence frames, sharp examples, and targeted exercises (MCQ, fill‑in‑the‑blank, error fixes) to lock in buy-side–caliber language and speed-to-publish.
