SpacBrain’s read on the price

No multiple can be computed

We hold no revenue figure in US dollars for SL BIO Ltd., so there is nothing to divide the price by and no multiple can be struck. It is not recorded as pre-revenue either — this is a gap in our record, not a finding that the company has no sales. The deal values it at $5.57bn regardless.

We have not extracted a revenue figure for this company from its filings yet. That is our gap, not a statement about the business.
