Aug 15 (Reuters) - Australian vitamin maker Blackmores Ltd's BKL.AX annual profit fell 23.6% and missed analysts' estimates on Thursday, hurt by decline in sales and tough e-commerce regulations in China, its largest offshore market.
Net profit attributable for the year ended June 30 fell to A$53.5 million ($36.12 million) compared with A$70 million a year earlier. An average of nine analysts expected profit of A$59.9 million, according to IBES data from Refinitiv.
The 87-year-old firm declared a final dividend of 70 Australian cents per share, down from 155 cents last year.
