We investigate whether voluntary disclosures of product and business expansion plans affect analyst coverage and forecasts. We find that the level of analyst coverage is positively associated with the incidence of disclosures of product and business expansion plans. We also find that product and business expansion disclosures increase the informativeness of analyst earnings forecasts. We find no evidence that product and business expansion disclosures increase analyst forecast errors. Overall, our study contributes to understanding the role of product and business expansion disclosures in analyst forecast behaviour.
