POET Technologies Completes C$13.8 Million “Bought Deal” Financing

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISSEMINATION IN THE UNITED STATES

Toronto, March 21, 2018 - POET Technologies Inc. (the "Company" or "POET") (TSXV: PTK; OTCQX: POETF) announces that it has completed its previously announced bought-deal financing of C$11,999,900 (the "Offering") plus the exercise in-full by a syndicate of underwriters led by Cormark Securities Inc. and including X.X. Xxxxxxxxxx & Co., LLC (the “Underwriters”) of the overallotment option of C$1,799,985 for a total gross proceeds of C$13,799,885. The total number of units of the Company ("Units") issued under the Offering was 25,090,700. Each Unit consisted of one common share of the Company (each a "Share") and one-half of one common share purchase warrant (each whole common share purchase warrant, a "Warrant"). Each Warrant entitles the holder to purchase one Common Share at a price equal to C$0.75 for a period of 24 months following the closing of the Offering which took place today.

The Units were offered in accordance with the terms of a prospectus supplement filed in all provinces in Canada except Quebec and in the United States on a private placement basis pursuant to an exemption from the registration requirements of the United States Securities Act of 1933, as amended, and in those jurisdictions outside of Canada and the United States which were agreed to by the Company and the Underwriters, where the securities were issued on a private placement basis, exempt from any prospectus, registration or other similar requirements.

The Company intends to use the net proceeds from the Offering for general corporate purposes, which may include, among other things, increased operating expenses from hiring of additional staff, capital equipment purchases, increased working capital requirements and further product development and sales activities, as well as potential business or intellectual property acquisitions in support of strategic growth.

The Underwriters were paid a cash commission equal to 6% of the gross proceeds raised under the Offering (including the exercise of the over-allotment option) and have also been issued broker warrants entitling them to purchase, in the aggregate, that number of Units as is equal to 6% of the number of Units sold in the Offering (including the Units sold pursuant to the over-allotment option) at price of $0.55 per Unit for a period of 24 months from the closing of the Offering.

This press release is not an offer or a solicitation of an offer of securities for sale in the United States. The securities have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and may not be offered or sold in the United States or to, or for the account or benefit of, any "U.S. person" (as defined in Regulation S under the U.S. Securities Act) absent registration or an applicable exemption from registration.

The Prospectus Supplement relating to the Offering is available free of charge on the SEDAR website at xxx.xxxxx.xxx and on the Company's website at xxx.xxxx-xxxxxxxxxxxx.xxx and electronic copies may also be obtained from the offices of Cormark Securities Inc. at 000 Xxx Xxxxxx, Xxxxxxx, Xxxxxxx, Xxxxxx (or by emailing xxxx@xxxxxxx.xxx) and from of X.X. Xxxxxxxxxx & Co., LLC at 000 Xxxx Xxxxxx, 0xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000 (or by emailing xxxxxxxxxx@xxxxx.xxx).
