The pullback reflects profit-taking and renewed focus on the substantial capital expenditure required for nearly one million square feet of new manufacturing capacity, alongside ongoing valuation concerns and insider selling trends. Volume of 446,683 shares remains normal for this point in the session (0.92x average).
