Release-to-release sector shifts aggregate each edition's exact published rows inside stable broad NAICS sectors. They are descriptive changes in the federal review pipeline, not merger rates, market-power measures, or causal estimates. Industry codes and labels that enter, exit, or change between tables remain explicit rather than being silently crosswalked.

Clearances and Second Requests are administrative review stages. Their counts and row-level rates do not indicate liability, remedy, competitive harm, or agency effectiveness.

An intra-industry transaction means the acquiring and acquired persons both reported revenue in the same 3-digit NAICS code. It does not establish a horizontal overlap, relevant antitrust market, or competitive effect.

Classification passport

Exact labels before analytical joins

Code identity is not a silent crosswalk

The release label, adjacent-release label, and Census 2022 label are shown independently. A matching code supports navigation; it does not prove statistical continuity when labels or source universes differ.

A NAICS industry is a statistical classification, not a legally defined antitrust market. Use these national revenue concentration measures to screen where deeper product and geographic market analysis may be warranted, not to infer market power or liability.

The FY2023 and FY2024 acquired-entity tables classify adjusted HSR transactions by 3-digit NAICS. They describe the federal review pipeline, not industry-wide merger rates, market definitions, competitive harm, or agency performance. Published row shares are independently rounded to one decimal place and therefore sum to 100.3% and 101.5%, respectively, while each official table total remains 100.0%.
