Making a deal more attractive: Some partnership deals include a stake in the biotech as part of the upfront payment. Issuing additional shares can facilitate this arrangement and provide the partner with an equity position.
Maybe the s3 is purely for funding and the share increase is to provide enough available shares for a large commitment from a partner? I would think a partner would want to have a financial stake that enables a board seat at minimum.
Just a thought
