PROSPECTUS SUPPLEMENT
(To Prospectus dated February 12, 2020)
14,000,000 Ordinary Shares
Warrants to Purchase 14,000,000 Ordinary Shares
We are offering 14,000,000 of our ordinary shares, and warrants to purchase 14,000,000 ordinary shares, in this offering. The public offering price for each ordinary share and accompanying warrant to purchase one ordinary share is $2.50. The warrants have an exercise price of $3.10 per share, are exercisable immediately and will expire three and one-half years from the date of issuance. We are also offering the ordinary shares that are issuable from time to time upon exercise of the warrants.
The ordinary shares and the accompanying warrants can only be purchased together in this offering but will be issued separately upon issuance. There is no established public trading market for the warrants, and we do not expect a market to develop.
Our ordinary shares are listed on the Nasdaq Global Select Market under the trading symbol “OSMT.” On October 6, 2021, the last reported sale price of our ordinary shares on the Nasdaq Global Select Market was $3.06 per share. We do not intend to apply for listing of the warrants on the Nasdaq Global Select Market or any securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be limited.
The public offering price per ordinary share and the public offering price per warrant will be determined by us, the underwriter, and investors based on market conditions at the time of pricing.
We are an “emerging growth company” as defined by the Jumpstart Our Business Startups Act of 2012 and, as such, we are subject to reduced public company reporting requirements for this prospectus supplement and future filings.
The offering is being underwritten on a firm commitment basis. The underwriter may offer the ordinary shares and warrants from time to time to purchasers directly or through agents, or through brokers in brokerage transactions on the Nasdaq Global Select Market, or to dealers in negotiated transactions or in a combination of such methods of sale, or otherwise, at fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices.
Investing in our ordinary shares and warrants involves a high degree of risk. Please read the “Risk Factors” beginning on page S-6 of this prospectus supplement, as well as in the accompanying prospectus and the documents incorporated by reference herein and therein, for a discussion of the factors you should carefully consider before deciding to purchase our ordinary shares and warrants.
