Using sample of Chinese listed firms from Q1 2017 to Q4 2022, this article examines the impact of economic policy uncertainty on share repurchases. We find that economic policy uncertainty significantly increases the probability and scale of open market share repurchases. Private enterprises, government-supported enterprises, innovative enterprises, and investment hotspot enterprises repurchased more shares during periods of high economic policy uncertainty. Additionally, the market value of repurchase programs issued during periods of high economic policy uncertainty is larger. We also discover that economic policy uncertainty substantially influences the characteristics, timing, and outcomes of the repurchase programs. Lastly, this article confirms that share repurchase behavior has a similar effect to voluntary disclosures and can alleviate the information asymmetry triggered by economic policy uncertainty. In summary, Chinese listed firms have resorted to more share repurchases during periods of high economic policy uncertainty to convey their actual value and boost investor confidence, aligning with the signaling motive. Open market share repurchases surface as an efficacious instrument to cope with the risk from economic policy uncertainty.
