Thirty trades went through for 4332619 shares in the closing auction. The last trade listed was 1 share and it was almost certainly a partial order to make up the total of someone's order rather than an order for one single share.
Even if it was a single share order - that would have made no difference to the closing price. The closing auction matches up the buy and sell orders and all 4332619 shares sold for the same price - 14c.
