HDSN Hudson Technologies Inc

Item 7.01. Regulation FD Disclosure

On December 5, 2016, Hudson Technologies, Inc. (the “Company”) issued a press release announcing a proposed underwritten public offering of its common stock (the “Offering”). A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

In connection with the Offering, the Company filed a preliminary prospectus supplement on December 5, 2016 (the “Prospectus Supplement”). The Prospectus Supplement sets forth the following disclosure under the heading “Prospectus Supplement Summary - Recent Developments”:

In conjunction with this offering, and given the proximity to the close of the fourth quarter of 2016, we have chosen to provide a range of estimated losses per share and revenues for the three months ending December 31, 2016, as well as additional refrigerant pricing trend information.  While we do not provide quarterly guidance, with respect to the fourth quarter of 2016, we estimate that the total loss per share, excluding the impact of this offering, will be between ($0.04) and ($0.05) and our revenues for the three months ending December 31, 2016, will be between $6.8 million and $7.5 million, which revenues are comparable to the prior year period.  In addition, we reiterate our expectation that the full-year 2017 will continue the trend of revenue growth and higher than average historical gross margins.  Moreover, during the fourth quarter of 2016, we are continuing to see further price increases for R-22 refrigerant.  No assurances can be given, however, that the results for the fourth quarter of 2016 will not differ from these estimated amounts. These estimated amounts and related trend information are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These estimated amounts and trends may or may not be realized, and they may be based upon judgments or assumptions that prove incorrect. Our results for this quarter or any future period may vary significantly from these amounts based on other unexpected issues in our business and operations.

The Company is furnishing the information in this Current Report on Form 8-K. Such information, including Exhibit 99.1, shall not be deemed “filed” for any purpose, including for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. The information in this Current Report on Form 8-K, including Exhibit 99.1, shall not be deemed incorporated by reference into any filing under the Securities Act or the Exchange Act, regardless of any general incorporation language in such filings.
