The e-commerce company says the increase means it raised a total of US$823.5-million before underwriting commission and offering costs.
The size of the share offering was initially set at seven million subordinate voting shares, but was later increased to 7.7 million shares at a price of US$93 per share.
The underwriters were also granted an over-allotment option for up to 1,155,000 additional shares, up from an initial 1,050,000.
Lightspeed says the money raised will be used primarily to strengthen its financial position and pursue its growth strategies.
Last week, the company raised its outlook as it reported revenue in the first quarter of its 2022 financial year more than tripled to US$115.9-million compared with US$36.2-million in the same quarter last year.
