    TNON is up 22.0%, with an 8.47% surge in the last five minutes, after commercially launching its titanium 3D-printed lateral screw. The Alpha launch generated approximately $1.2 million in incremental revenue, providing a concrete commercial validation for the full rollout.

    WHYA 22% move on a full commercial launch backed by approximately $1.2 million of incremental Alpha-launch revenue is substantial but proportionate, especially with a 667K-share float and extreme volume.
