Abstract
Purpose The purpose of this paper is to analyze and compare the performance of corporate acquisitions between the pre- and post-SOX periods, using both short-term and long-term analyses. Design/methodology/approach The sample includes 9,463 mergers and tender offers undertaken by publicly traded US firms between 1996 and 2009. The authors used the standard event study methodology for short-term performance analysis; Berkovitch and Narayanan (1993) method to identify merger motives; and standard benchmark adjusted return on assets (sales) (Barber and Lyon, 1996) and buy-and-hold abnormal returns (Mitchell and Stafford, 2000) to analyze long-term performance. Findings Compared to the pre-SOX period, US acquirers experience significantly higher announcement returns in the post-SOX period; the results are robust to various controls like bidder, target and deal characteristics, bidder management quality, and product market competition. Similar results (in favor of post-SOX US acquirers) are obtained with long-term post-acquisition operating and stock performance analyses. Research limitations/implications This paper only addressed domestic acquisitions. Originality/value This paper adds to the growing body of research on the impact of SOX on publicly traded US corporations. By examining corporate acquisitions, an important long-term investment decision for a firm, the paper shows that despite the complex nature of SOX, substantial compliance costs and the unintended negative consequence it engendered, the act had a beneficial impact in an important area of corporate finance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
