As of today's close, NEOS @$1.26 is overpriced. The merger calls for NEOS shareholders t receive 0.1088 shares of AYTU for each share of NEOS, which equates to $0.98 per NEOS share at today's closing price of AYTU.
A second bidder for NEOS is unlikely (IMO), so there's no reason NEOS should be trading about its buyout value.
