Yes. the key point here is book value per share and not just book value. Banks are generally valued on price/book basis so book value is important for banks. Managements generally exclude the per share numbers and only present the numerator. For financial companies, if the numerator (book value, assets, earnings etc) has to grow faster than sustainable growth rate, the denominator also has to grow although not at the same rate.
These presentations generally give a clue on what growth opportunities managements sees which a good piece of information. However financial companies on one hand have to comply with capital adequacy norms so they cannot leverage their equity too much and on the other hand borrowing-lending business being a commodity business they cannot earn a high ROE. Which means to actually realize these high growth opportunities they have to regularly issue capital.
Large private sector banks have routinely issued capital as they saw opportunities to grow faster than their sustainable rate and PSU banks have issued capital whenever they were bailed out by government after a crisis.
Growth in book value per share = EPS - DPS plus any premium they received by selling shares at a premium to book value. So EPS is important as it determines growth in book value. the last term becomes more important when shares are selling at a high p/b ratio. By selling shares at a huge premium to book (Yes bank raised Rs 5000 Cr at 4 times book), a bank can grow it book value much faster than earnings growth. If shares are selling close to book value, there is not much benefit to existing shareholders as growth in book value is offset by growth in number of shares so per share book value does not grow much.
