If there's a 10 to 1 reverse split and there's 4 billion shares how many will there be after the split

After a 10-to-1 reverse split, the number of shares will be reduced to approximately 40 million shares.

1. **Reverse Stock Split Ratio**: A reverse stock split ratio of 10-to-1 means that each existing share will be consolidated into one new share.
2. **Initial Share Count**: The initial number of shares was 4 billion shares.
3. **Post-Split Share Count**: Applying the reverse split ratio, the post-split number of shares can be calculated as follows:
- New shares = (4 billion shares) / (10 × 1) = 40 million shares.
