There are no earnings announcements on my watchlist after the close today (April 29) and before the open on Monday (May 2). The next earnings from my list are after the close on Monday.
My list is composed of 143 stocks from the CBOE's penny increment options list. The goal in harvesting them was to get issues with volumes down to around AMZN's.
So, there may well be significant earnings announcements in this period -- they're just not on my current list. I make to claims to thoroughness in this matter.
