I believe that one factor that has held back share price growth has been the probability that the company would need to issue new equity to accommodate its rapid capital investment growth (which has been more rapid than expected earlier this year or even three months ago), or the possibility of equity sales or secondary offerings by large holder(s).
In responding to a question at the conference call, the CFO said that the company is comfortable with a range of debt-to-equity ratios of 3.0 to 3.5 times. Q2 ended at 2.9 times. This means that there can be a lot of growth ahead without potential dilution from the issuance of new equity.
Some analysts have already increased earnings projections for Q3 and for the full year and have raised their share target prices.
