We examine the relation between firms' voluntary guidance and mandatory 8K filings. We find a negative relation between guidance and 8Ks, which strengthens following the 2004 expansion of mandatory 8K requirements, consistent with firms using the disclosures as substitutes. Increases in 8Ks coincide with declines in firms’ profits, but this negative relation weakens after the 2004 regulation, consistent with firms broadening the scope of information conveyed through 8Ks. Together, our findings suggest firms became more reliant on 8Ks to convey general types of information after the 2004 regulation, rather than primarily negative news, which reduces their incentives to issue guidance.

Firms with central boards of directors earn superior risk-adjusted stock returns. A long (short) position in the most (least) central firms earns average annual returns of 4.68%. Firms with central boards also experience higher future return-on-assets growth and more positive analyst forecast errors. Return prediction, return-on-assets growth, and analyst errors are concentrated among high growth opportunity firms or firms confronting adverse circumstances, consistent with boardroom connections mattering most for firms standing to benefit most from information and resources exchanged through boardroom networks. Overall, our results suggest that director networks provide economic benefits that are not immediately reflected in stock prices.
