"To ensure that they are paid as soon as possible, SLI encourages shareholders and option-holders who have not accepted ESW's offer to promptly return the transfer form to ESW," chair Greg Cross said in a statement.
The offer was a substantial premium to the 30 cents the stock was trading at before ESW made its bid and more than the 37-to-53 cents a share valuation range put on the software firm by Northington Partners. SLI shares ended 2018 at 64 cents, having started the year at just 20 cents.
SLI has been a perennial underachiever since listing in 2013, when it raised $27m at $1.50 a share. Early investors Pioneer Capital and New Zealand Venture Investment Fund sold out of SLI earlier last year at 25 cents a share, ending a decade-long involvement.
They injected $1 million into the start-up to help fund its global expansion plans, held 16 per cent of SLI before its initial public offering and were among shareholders who sold $12m of shares into the IPO.
The New Zealand software-as-a-service firm was on the road to recovery before the ESW offer emerged, reporting a maiden profit last year.
In 2017, SLI changed tack to focus on a self-service model where customers can more easily build their own search capabilities as retailers facing the pinch refrained from deploying a number of different technologies at once.
Austin, Texas-based ESW buys and grows software companies, targeting firms with an enterprise value of between US$10m and US$250m.
It has said it plans to invest in SLI's global business to ensure long-term viability, new product innovation and using its existing top-tier retail relationships to expand the business. The Texan firm will also review SLI's capital structure and replace the chief executive and chief financial officer.
