Business General Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutionsto recurring problems within the refrigeration industry. The Company’s operations consist of one reportable segment. The Company's products and servicesare primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerantmanagement services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer's site, consisting of systemdecontamination to remove moisture, oils and other contaminants. In addition, the Company’s SmartEnergy OPSTM service is a web-based real timecontinuous monitoring service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and ChillSmart® services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also participatesin the generation of carbon offset projects. The Company operates principally through its wholly-owned subsidiary, Hudson Technologies Company. Unlessthe context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and itssubsidiaries. The Company's executive offices are located at One Blue Hill Plaza, Pearl River, New York and its telephone number is (845) 735-6000. Industry Background The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results.Currently the Company purchases virgin, hydro chlorofluorocarbon (“HCFC”) and hydro fluorocarbon (“HFC”) refrigerants and reclaimable, primarilyHCFC, HFC and chlorofluorocarbon (“CFC”) refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act, as amended (the“Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act furtherlimited the production of virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances forHCFC refrigerants and which imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFCrefrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased outby 2030. In April 2013, the Environmental Protection Agency (“EPA”) published a final rule providing for the production or importation of 63 million and51 million pounds of HCFC-22 in 2013 and 2014, respectively. In October 2014, the EPA published a final rule providing further reductions in theproduction and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA hasestablished a linear annual phase down schedule for the production or importation of virgin HCFC-22 that started at approximately 22 million pounds in2015 and reduces by approximately 4.5 million pounds each year and ends at zero in 2020. HFC refrigerants are used as substitutes for CFC and HCFC refrigerants in certain applications. As a result of the increasing restrictions and limitations on theproduction and use of CFC and HCFC refrigerants, various segments of the air conditioning and refrigeration industry have been replacing or modifyingequipment that utilize CFC and HCFC refrigerants and have been transitioning to equipment that utilize HFC refrigerants and hydrofluoro-olefins (“HFO”).HFC refrigerants are not ozone depleting chemicals and are not currently regulated under the Act. However, certain HFC refrigerants are highly weightedgreenhouse gases that are believed to contribute to global warming and climate change and, as a result, are now subject to various state and federalregulations relating to the sale, use and emissions of HFC refrigerants. In addition, federal legislation has been proposed that, if enacted, would imposelimitations on the production and importation of certain virgin HFC refrigerants. The Company expects that HFC refrigerants eventually will be replaced byHFOs or other types of products with lower global warming potentials. The Act, and the federal regulations enacted under authority of the Act, have mandated and/or promoted responsible use practices in the air conditioning andrefrigeration industry, which are intended to minimize the release of refrigerants into the atmosphere and encourage the recovery and re-use of refrigerants.The Act prohibits the venting of CFC, HFC and HCFC refrigerants, and prohibits and/or phases down the production of CFC and HCFC refrigerants. The Act also mandates the recovery of CFC and HCFC refrigerants and also promotes and encourages re-use and reclamation of CFC and HCFC refrigerants.Under the Act, owners, operators and companies servicing cooling equipment utilizing CFC and HCFC refrigerants are responsible for the integrity of thesystems regardless of the refrigerant being used. In November 2015, the EPA published a proposed rule that, if enacted, will extend these requirements toHFCs and to certain other refrigerants that are approved by the EPA as alternatives for CFC and HCFC refrigerants. 3 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Products and Services From its inception, the Company has sold refrigerants, and has provided refrigerant reclamation and refrigerant management services that are designed torecover and reuse refrigerants, thereby protecting the environment from release to the atmosphere and the corresponding ozone depletion and global warmingimpact. The reclamation process allows the refrigerant to be re-used thereby eliminating the need to destroy or manufacture additional refrigerant andeliminating the corresponding impact to the environment associated with the destruction and manufacturing. The Company believes it is the largestrefrigerant reclaimer in the United States. Additionally, the Company has created alternative solutions to reactive and preventative maintenance proceduresthat are performed on commercial and industrial refrigeration systems. These services, known as RefrigerantSide® Services, complement the Company’srefrigerant sales and refrigerant reclamation and management services. The Company has also developed SmartEnergy OPSTM that identify inefficiencies inthe operation of air conditioning and refrigeration systems and assists companies to improve the energy efficiency of their systems and save operating costsand improve system reliability. In addition, the Company is pursuing potential opportunities for the creation and monetization of verified emissionreductions. Refrigerant and Industrial Gas Sales The Company sells reclaimed and virgin (new) refrigerants to a variety of customers in various segments of the air conditioning and refrigeration industry,and sells industrial gases to a variety of industry segments. The Company continues to sell reclaimed CFC based refrigerants, which are no longermanufactured. Virgin, non-CFC refrigerants, including HCFC and HFC refrigerants, are purchased by the Company from several suppliers and resold by theCompany, typically at wholesale. Additionally, the Company regularly purchases used or contaminated refrigerants, some of which are CFC based, frommany different sources, which refrigerants are then reclaimed using the Company's high speed proprietary reclamation equipment, its proprietary Zugibeast®system, and then are resold by the Company. Refrigerant Management Services The Company provides a complete offering of refrigerant management services, which primarily include reclamation of refrigerants, laboratory testingthrough the Company’s laboratory, which has been certified by the Air Conditioning, Heating and Refrigeration Institute (“AHRI”), and banking (storage)services tailored to individual customer requirements. Hudson also separates “crossed” (i.e. commingled) refrigerants and provides re-usable cylinderrefurbishment and hydrostatic testing services. RefrigerantSide® Services The Company provides decontamination and recovery services that are performed at a customer's site through the use of portable, high volume, high-speedproprietary equipment, including the patented Zugibeast® system. Certain of these RefrigerantSide® Services, which encompass system decontamination,and refrigerant recovery and reclamation are also proprietary and are covered by process patents. In addition to the decontamination and recovery services previously described, the Company also provides predictive and diagnostic services for itscustomers. The Company offers diagnostic services that are intended to predict potential problems in air conditioning and refrigeration systems before theyoccur. The Company’s Chiller Chemistry® offering integrates several fluid tests of an operating system and the corresponding laboratory results into anengineering report providing its customers with an understanding of the current condition of the fluids, the cause for any abnormal findings and the potentialconsequences if the abnormal findings are not remediated. Fluid Chemistry®, an abbreviated version of the Company’s Chiller Chemistry® offering, isdesigned to quickly identify systems that require further examination. The Company has also been awarded several US patents for its SmartEnergy OPSTM, which is a system for measuring, modifying and improving theefficiency of energy systems, including air conditioning and refrigeration systems, in industrial and commercial applications. This service is a web-based realtime continuous monitoring service applicable to a facility’s chiller plant systems. The SmartEnergy OPSTM offering enables customers to monitor andimprove their chiller plant performance and proactively identify and correct system inefficiencies. SmartEnergy OPSTM is able to identify specificinefficiencies in the operation of chiller plant systems and, when used with Hudson’s RefrigerantSide® Services, can increase the efficiency of the operatingsystems thereby reducing energy usage and costs. Improving the system efficiency reduces power consumption thereby directly reducing CO2 emissions atthe power plants or onsite. Lastly, the Company’s ChillSmart® offering, which combines the system optimization with the Company’s Chiller Chemistry®offering, provides a snapshot of a packaged chiller’s operating efficiency and health. ChillSmart® provides a very effective predictive maintenance tool andhelps our customers to identify the operating chillers that cause higher operating costs. The Company’s engineers who developed and support Smart Energy OPSTM are recognized as Energy Experts and Qualified Best Practices Specialists by theUnited States Department of Energy (“DOE”) in the areas of Steam and Process Heating under the DOE “Best Practices” program, and are the LeadInternational Energy Experts for steam, chillers and refrigeration systems for the United Nations Industrial Development Organization (“UNIDO”). TheCompany’s staff have trained more than 4,000 industrial plant personnel in the US and internationally, and have developed and are currently deliveringtraining curriculums in 12 different countries. The Company’s staff have completed more than 200 industrial ESAs in the US and internationally. 4 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Thedestruction of CFC refrigerants may be eligible for verified emission reductions that can be converted and monetized into carbon offset credits that may betraded in the emerging carbon offset markets. The Company is pursuing opportunities to acquire CFC refrigerants and is developing relationships within theemerging environmental markets in order to develop opportunities for the creation and monetization of verified emission reductions from the destruction ofCFC refrigerants. In October 2015, the American Carbon Registry (“ACR”) established a methodology to provide, among other things, a quantification framework for thecreation of carbon offset credits for the use of certified reclaimed HFC refrigerants. The Company is pursuing opportunities to acquire HFC refrigerants and isdeveloping relationships within the emerging environmental markets in order to develop opportunities for the creation and monetization of verified emissionreductions from the reclamation of HFC refrigerants.

The Company has Alliances in Europe and South Africa, and over time, the Company expects to introduce its technology and offerings toseveral other markets around the world. Suppliers The Company's financial performance and its ability to sell refrigerants is in part dependent on its ability to obtain sufficient quantities of virgin, non-CFCbased refrigerants, and of reclaimable CFC and non-CFC based, refrigerants from manufacturers, wholesalers, distributors, bulk gas brokers and from othersources within the air conditioning, refrigeration and automotive aftermarket industries, and on corresponding demand for refrigerants. The Company'srefrigerant sales include CFC based refrigerants, which are no longer manufactured. Additionally, the Company's refrigerant sales include non-CFC basedrefrigerants, including HCFC and HFC refrigerants, which are the most-widely used refrigerants. Effective January 1, 1996, the Act limited the production ofvirgin HCFC refrigerants, which production was further limited in January 2004. Federal regulations enacted in January 2004 established production andconsumption allowances for HCFCs and imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certainvirgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020 and production of all virgin HCFC refrigerants is scheduled tobe phased out by 2030. In October 2014, the EPA published the Final Rule providing further reductions in the production and consumption allowances forvirgin HCFC refrigerants for the years 2015 through 2019. In the Final Rule, the EPA has established a linear annual phase down schedule for the productionor importation of virgin HCFC-22 that will start at approximately 22 million pounds in 2015 and reduce by approximately 4.5 million pounds each year andend at zero in 2020. 5 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Customers The Company provides its services to commercial, industrial and governmental customers, as well as to refrigerant wholesalers, distributors, contractors andto refrigeration equipment manufacturers. Agreements with larger customers generally provide for standardized pricing for specified services. For the year ended December 31, 2015, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 33% of the Company’s revenues. At December 31, 2015, there were no outstanding receivables from these customers. For the year ended December 31, 2014, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 25% of the Company’s revenues. At December 31, 2014, there were $688,000 in outstanding receivables from these customers. Marketing Marketing programs are conducted through the efforts of the Company's executive officers, Company sales personnel, and third parties. Hudson employsvarious marketing methods, including direct mailings, technical bulletins, in-person solicitation, print advertising, response to quotation requests and theinternet through the Company’s website (www.hudsontech.com). Information on the Company's website is not part of this report. The Company's sales personnel are compensated on a combination of a base salary and commission. The Company's executive officers devote significanttime and effort to customer relationships. Competition The Company competes primarily on the basis of the performance of its proprietary high volume, high-speed equipment used in its operations, the breadth ofservices offered by the Company, including proprietary RefrigerantSide® Services and other on-site services, and price, particularly with respect torefrigerant sales. The Company competes with numerous regional and national companies that market reclaimed and virgin refrigerants and provide refrigerant reclamationservices. Certain of these competitors possess greater financial, marketing, distribution and other resources for the sale and distribution of refrigerants than theCompany and, in some instances, serve a more extensive geographic area than the Company. Hudson's RefrigerantSide® Services provide new and innovative solutions to certain problems within the refrigeration industry and, as such, the demand andmarket acceptance for these services are subject to uncertainty. Competition for these services primarily consists of traditional methods of solving theindustry's problems. The Company’s marketing strategy is to educate the marketplace that its alternative solutions are available and that RefrigerantSide®Services are superior to traditional methods. Insurance The Company carries insurance coverage that it considers sufficient to protect the Company's assets and operations. The Company currently maintainsgeneral commercial liability insurance and excess liability coverage for claims up to $11,000,000 per occurrence and $12,000,000 in the aggregate. TheCompany attempts to operate in a professional and prudent manner and to reduce potential liability risks through specific risk management efforts, includingongoing employee training. The refrigerant industry involves potentially significant risks of statutory and common law liability for environmental damage and personal injury. TheCompany, and in certain instances, its officers, directors and employees, may be subject to claims arising from the Company's on-site or off-site services,including the improper release, spillage, misuse or mishandling of refrigerants classified as hazardous or non-hazardous substances or materials. TheCompany may be held strictly liable for damages, which could be substantial, regardless of whether it exercised due care and complied with all relevant lawsand regulations. Hudson maintains environmental impairment insurance of $10,000,000 per occurrence, and $10,000,000 annual aggregate, for events occurring subsequentto November 1996. Government Regulation The business of refrigerant sales, reclamation and management is subject to extensive, stringent and frequently changing federal, state and local laws andsubstantial regulation under these laws by governmental agencies, including the EPA, the United States Occupational Safety and Health Administration(“OSHA”) and the United States Department of Transportation (“DOT”). 6 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Among other things, these regulatory authorities impose requirements which regulate the handling, packaging, labeling, transportation and disposal ofhazardous and non-hazardous materials and the health and safety of workers, and require the Company and, in certain instances, its employees, to obtain andmaintain licenses in connection with its operations. This extensive regulatory framework imposes significant compliance burdens and risks on the Company. Hudson and its customers are subject to the requirements of the Act, and the regulations promulgated thereunder by the EPA, which make it unlawful for anyperson in the course of maintaining, servicing, repairing, and disposing of air conditioning or refrigeration equipment, to knowingly vent or otherwise releaseor dispose of ozone depleting substances, and non-ozone depleting substitutes, used as refrigerants. Pursuant to the Act, reclaimed refrigerant must satisfy the same purity standards as newly manufactured, virgin refrigerants in accordance with standardsestablished by AHRI prior to resale to a person other than the owner of the equipment from which it was recovered. The EPA administers a certificationprogram pursuant to which applicants certify to reclaim refrigerants in compliance with AHRI standards. The Company is one of only three certifiedrefrigerant testing laboratories in the United States under AHRI’s laboratory certification program, which is a voluntary program that certifies the ability of alaboratory to test refrigerant in accordance with the AHRI 700 standard. In addition, the EPA has established a mandatory certification program for air conditioning and refrigeration technicians. Hudson's technicians have appliedfor or obtained such certification. The Company may also be subject to regulations adopted by the EPA which impose certain reporting requirements arising out of the importation of certainHCFCs, and arising out of the importation, purchase, production, use and/or emissions of certain greenhouse gases, including HFCs. The Company is also subject to regulations adopted by the DOT which classify most refrigerants handled by the Company as hazardous materials orsubstances and imposes requirements for handling, packaging, labeling and transporting refrigerants and which regulate the use and operation of theCompany’s commercial motor vehicles used in the Company’s business. The Resource Conservation and Recovery Act of 1976, as amended ("RCRA"), requires facilities that treat, store or dispose of hazardous wastes to complywith certain operating standards. Before transportation and disposal of hazardous wastes off-site, generators of such waste must package and label theirshipments consistent with detailed regulations and prepare a manifest identifying the material and stating its destination. The transporter must deliver thehazardous waste in accordance with the manifest to a facility with an appropriate RCRA permit. Under RCRA, impurities removed from refrigerantsconsisting of oils mixed with water and other contaminants are not presumed to be hazardous waste. The Emergency Planning and Community Right-to-Know Act of 1986, as amended, requires the annual reporting by the Company of Emergency andHazardous Chemical Inventories (Tier II reports) to the various states in which the Company operates and requires the Company to file annual ToxicChemical Release Inventory Forms with the EPA. The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”), establishes liability for clean-up costs andenvironmental damages to current and former facility owners and operators, as well as persons who transport or arrange for transportation of hazardoussubstances. Almost all states have similar statutes regulating the handling and storage of hazardous substances, hazardous wastes and non-hazardous wastes.Many such statutes impose requirements that are more stringent than their federal counterparts. The Company could be subject to substantial liability underthese statutes to private parties and government entities, in some instances without any fault, for fines, remediation costs and environmental damage, as aresult of the mishandling, release, or existence of any hazardous substances at any of its facilities. The Occupational Safety and Health Act of 1970, as amended mandates requirements for a safe work place for employees and special procedures andmeasures for the handling of certain hazardous and toxic substances. State laws, in certain circumstances, mandate additional measures for facilities handlingspecified materials. The Company is also subject to regulations adopted by the California Air Resources Board which impose certain reporting requirements arising out of thereclamation and sale of refrigerants that takes place within the State of California. The Company believes that it is in material compliance with all applicable regulations material to its business operations. Quality Assurance & Environmental Compliance The Company utilizes in-house quality and regulatory compliance control procedures. Hudson maintains its own analytical testing laboratory, which isAHRI certified, to assure that reclaimed refrigerants comply with AHRI purity standards and employs portable testing equipment when performing on-siteservices to verify certain quality specifications. The Company employs ten persons engaged full-time in quality control and to monitor the Company'soperations for regulatory compliance. 7 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

None of the Company's employees are represented by a union. The Company believes that its employee relations aregood. Patents and Proprietary Information The Company holds several U.S. and foreign patents, as well as pending patent applications, related to certain RefrigerantSide® Services and supportingsystems developed by the Company for systems and processes for measuring and improving the efficiency of refrigeration systems, and for certain refrigerantrecycling and reclamation technologies. These patents will expire between February 2017 and April 2032. The Company believes that patent protection is important to its business. There can be no assurance as to the breadth or degree of protection that patents mayafford the Company, that any patent applications will result in issued patents or that patents will not be circumvented or invalidated. Technologicaldevelopment in the refrigerant industry may result in extensive patent filings and a rapid rate of issuance of new patents. Although the Company believesthat its existing patents and the Company's equipment do not and will not infringe upon existing patents or violate proprietary rights of others, it is possiblethat the Company's existing patent rights may not be valid or that infringement of existing or future patents or violations of proprietary rights of others mayoccur. In the event the Company's equipment or processes infringe, or are alleged to infringe, patents or other proprietary rights of others, the Company maybe required to modify the design of its equipment or processes, obtain a license or defend a possible patent infringement action. There can be no assurancethat the Company will have the financial or other resources necessary to enforce or defend a patent infringement or proprietary rights violation action or thatthe Company will not become liable for damages. The Company also relies on trade secrets and proprietary know-how, and employs various methods to protect its technology. However, such methods may notafford complete protection and there can be no assurance that others will not independently develop such know-how or obtain access to the Company'sknow-how, concepts, ideas and documentation. Failure to protect its trade secrets could have a material adverse effect on the Company. Item 1A. Risk Factors There are many important factors, including those discussed below (and above as described under “Patents and Proprietary Information”), that have affected,and in the future could affect Hudson’s business including, but not limited to, the factors discussed below, which should be reviewed carefully together withthe other information contained in this report. Some of the factors are beyond Hudson’s control and future trends are difficult to predict. Our existing and future debt obligations could impair our liquidity and financial condition. Our existing credit facility, which currently expires in June 2018, is secured by substantially all of our assets and contains formulas that limit the amount ofour borrowings under the facility. Moreover, the terms of our credit facility also include negative covenants that, among other things, may limit our ability toincur additional indebtedness. If we violate any loan covenants and do not obtain a waiver from our lender, our indebtedness under the credit facility wouldbecome immediately due and payable, and the lender could foreclose on its security, which could materially adversely affect our business and futurefinancial condition and could require us to curtail or otherwise cease our existing operations. We may need additional financing to satisfy our future capital requirements, which may not be readily available to us. Our capital requirements may be significant in the future. In the future, we may incur additional expenses in the development and implementation of ouroperations. Due to fluctuations in the price, demand and availability of new refrigerants, our existing credit facility that expires in June 2018 may not in thefuture be sufficient to provide all of the capital that we need to acquire and manage our inventories of new refrigerant. As a result, we may be required to seekadditional equity or debt financing in order to develop our RefrigerantSide® Services business, our refrigerant sales business and our other businesses. Wehave no current arrangements with respect to, or sources of, additional financing other than our existing credit facility. There can be no assurance that we willbe able to obtain any additional financing on terms acceptable to us or at all. Our inability to obtain financing, if and when needed, could materiallyadversely affect our business and future financial condition and could require us to curtail or otherwise cease our existing operations. 8 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Weather is a significant factor in determining market demand for therefrigerants sold by us, and to a lesser extent, our RefrigerantSide® Services. Unusually cool temperatures in the spring and summer tend to depress demandfor, and price of, refrigerants we sell. Protracted periods of cooler than normal spring and summer weather could result in a substantial reduction in our saleswhich could adversely affect our financial position as well as our results of operations. An economic downturn could cause customers to postpone or cancelpurchases of the Company’s products or services. Either or both of these conditions could have severe negative implications to our business that mayexacerbate many of the risk factors we identified in this report but not limited, to the following: Liquidity These conditions could reduce our liquidity and this could have a negative impact on our financial condition and results of operations. Demand These conditions could lower the demand and/or price for our product and services, which would have a negative impact on our results of operations. The nature of our business exposes us to potential liability. The refrigerant recovery and reclamation industry involves potentially significant risks of statutory and common law liability for environmental damage andpersonal injury. We, and in certain instances, our officers, directors and employees, may be subject to claims arising from our on-site or off-site services,including the improper release, spillage, misuse or mishandling of refrigerants classified as hazardous or non-hazardous substances or materials. We may bestrictly liable for damages, which could be substantial, regardless of whether we exercised due care and complied with all relevant laws and regulations. Ourcurrent insurance coverage may not be sufficient to cover potential claims, and adequate levels of insurance coverage may not be available in the future at areasonable cost. A partially or completely uninsured claim against us, if successful and of sufficient magnitude would have a material adverse effect on ourbusiness and financial condition. Our business and financial condition is substantially dependent on the sale and continued environmental regulation of refrigerants. Our business and prospects are largely dependent upon continued regulation of the use and disposition of refrigerants. Changes in government regulationsrelating to the emission of refrigerants into the atmosphere could have a material adverse effect on us. Failure by government authorities to otherwisecontinue to enforce existing regulations or significant relaxation of regulatory requirements could also adversely affect demand for our services and products. Our business is subject to significant regulatory compliance burdens. The refrigerant reclamation and management business is subject to extensive, stringent and frequently changing federal, state and local laws and substantialregulation under these laws by governmental agencies, including the EPA, the OSHA and DOT. Although we believe that we are in material compliance withall applicable regulations material to our business operations, amendments to existing statutes and regulations or adoption of new statutes and regulationswhich affect the marketing and sale of refrigerant could require us to continually alter our methods of operation and/or discontinue the sale of certain of ourproducts resulting in costs to us that could be substantial. We may not be able, for financial or other reasons, to comply with applicable laws, regulations andpermit requirements, particularly as we seek to enter into new geographic markets. Our failure to comply with applicable laws, rules or regulations or permitrequirements could subject us to civil remedies, including substantial fines, penalties and injunctions, as well as possible criminal sanctions, which would, ifof significant magnitude, materially adversely impact our operations and future financial condition. A number of factors could negatively impact the price and/or availability of refrigerants, which would, in turn, adversely affect our business and financialcondition. Refrigerant sales continue to represent a significant portion of our revenues. Therefore, our business is substantially dependent on the availability of bothnew and used refrigerants in large quantities, which may be affected by several factors including, without limitation: (i) commercial production andconsumption limitations imposed by the Act and legislative limitations and ban on HCFC refrigerants; (ii) the ban on production of CFC based refrigerantsunder the Act; (iii) the proposed legislation which, if enacted, could impose limitations on production and consumption of HFC refrigerants; (iv) introductionof new refrigerants and air conditioning and refrigeration equipment; (v) price competition resulting from additional market entrants; (vi) changes ingovernment regulation on the use and production of refrigerants; and (vii) reduction in demand for refrigerants. We do not maintain firm agreements with anyof our suppliers of refrigerants and we do not hold allowances permitting us to purchase and import HCFC refrigerants from abroad. Sufficient amounts of newand/or used refrigerants may not be available to us in the future, particularly as a result of the further phase down of HCFC production, or may not beavailable on commercially reasonable terms. Additionally, we may be subject to price fluctuations, periodic delays or shortages of new and/or usedrefrigerants. Our failure to obtain and resell sufficient quantities of virgin refrigerants on commercially reasonable terms, or at all, or to obtain, reclaim andresell sufficient quantities of used refrigerants would have a material adverse effect on our operating margins and results of operations. 9 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. As a result of competition, and the strength of some of our competitors in the market, we may not be able to compete effectively. The markets for our services and products are highly competitive. We compete with numerous regional and national companies which provide refrigerantrecovery and reclamation services, as well as companies which market and deal in new and reclaimed alternative refrigerants, including certain of oursuppliers, some of which possess greater financial, marketing, distribution and other resources than us. We also compete with numerous manufacturers ofrefrigerant recovery and reclamation equipment. Certain of these competitors have established reputations for success in the service of air conditioning andrefrigeration systems. We may not be able to compete successfully, particularly as we seek to enter into new markets. Issues relating to potential global warming and climate change could have an impact on our business. Refrigerants are considered to be strong greenhouse gases that are believed to contribute to global warming and climate change and are now subject tovarious state and federal regulations relating to the sale, use and emissions of refrigerants. In addition, federal legislation has been proposed that, if enacted,would impose limitations on the production and importation of certain virgin HFC refrigerants, and current and future global warming and climate change orrelated legislation and/or regulations may impose additional compliance burdens on us and on our customers and suppliers which could potentially result inincreased administrative costs, decreased demand in the marketplace for our products, and/or increased costs for our supplies and products. The loss of key management personnel would adversely impact our business. Our success is largely dependent upon the efforts of our Chief Executive Officer and Chairman. The loss of his services would have a material adverse effecton our business and prospects. We have the ability to designate and issue preferred stock, which may have rights, preferences and privileges greater than Hudson’s common stock andwhich could impede a subsequent change in control of us. Our Certificate of Incorporation authorizes our Board of Directors to issue up to 5,000,000 shares of “blank check” preferred stock and to fix the rights,preferences, privileges and restrictions, including voting rights, of these shares, without further shareholder approval. The rights of the holders of our commonstock will be subject to, and may be adversely affected by, the rights of holders of any additional preferred stock that may be issued by us in the future. Ourability to issue preferred stock without shareholder approval could have the effect of making it more difficult for a third party to acquire a majority of ourvoting stock, thereby delaying, deferring or preventing a change in control of us. If our common stock were delisted from NASDAQ it would be subject to “penny stock” rules which could negatively impact its liquidity and ourshareholders’ ability to sell their shares. Our common stock is currently listed on the NASDAQ Capital Market. We must comply with numerous NASDAQ Marketplace rules in order to continue thelisting of our common stock on NASDAQ. There can be no assurance that we can continue to meet the rules required to maintain the NASDAQ listing of ourcommon stock. If we are unable to maintain our listing on NASDAQ, the market liquidity of our common stock may be severely limited. Our management has significant control over our affairs. Currently, our officers and directors collectively own approximately 20% of our outstanding common stock. Accordingly, our officers and directors are in aposition to significantly affect major corporate transactions and the election of our directors. There is no provision for cumulative voting for our directors. We may fail to successfully integrate any acquisitions made by us into our operations. As part of our business strategy, we may look for opportunities to grow by acquiring other product lines, technologies or facilities that complement or expandour existing business. We may be unable to identify suitable acquisition candidates or negotiate acceptable terms. In addition, we may not be able tosuccessfully integrate any assets, liabilities, customers, systems or management personnel we may acquire into our operations and we may not be able torealize related revenue synergies and cost savings within expected time frames. There can be no assurance that we will be able to successfully integrate anyprior or future acquisition. 10 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Legal Proceedings On April 1, 1999, the Company reported a release of approximately 7,800 lbs. of R-11 refrigerant (the “1999 Release”), at its former leased facility inHillburn, NY (the “Hillburn Facility”), which the Company vacated in June 2006. Since September 2000, last modified in March 2013, the Company signed an Order on Consent with the New York State Department of EnvironmentalConservation (“DEC”) whereby the Company agreed to operate a remediation system to reduce R-11 refrigerant levels in the groundwater under and aroundthe Hillburn Facility and agreed to perform periodic testing at the Hillburn Facility until remaining groundwater contamination has been effectively abated.The Company accrued, as an expense in its consolidated financial statements, the costs that the Company believes it will incur in connection with itscompliance with the Order of Consent through December 31, 2018. There can be no assurance that additional testing will not be required or that theCompany will not incur additional costs and such costs in excess of the Company’s estimate may have a material adverse effect on the Company financialcondition or results of operations. The Company has exhausted all insurance proceeds available for the 1999 Release under all applicable policies. In May 2000 the Hillburn facility, as a result of the 1999 release, was nominated by EPA for listing on the National Priorities List (“NPL”) pursuant toCERCLA. In September 2003, the EPA advised the Company that it had no current plans to finalize the process for listing of the Hillburn facility on the NPL. During the year ended December 31, 2014 the Company incurred $53,000 in additional remediation costs in connection with the matters above. There wereno costs incurred during the year ended December 31, 2015. There can be no assurance that the ultimate outcome of the 1999 Release will not have a materialadverse effect on the Company's financial condition and results of operations. There can be no assurance that the EPA will not change its current plans andseek to finalize the process of listing the Hillburn Facility on the NPL, or that the ultimate outcome of such a listing will not have a material adverse effect onthe Company's financial condition and results of operations.

Item 6. Selected Financial Data Not Applicable Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Certain statements, contained in this section and elsewhere in this Form 10-K, constitute “forward-looking statements” within the meaning of the PrivateSecurities Litigation Reform Act of 1995. Such forward-looking statements involve a number of known and unknown risks, uncertainties and other factorswhich may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance orachievements expressed or implied by such forward-looking statements. Such factors include, but are not limited to, changes in the laws and regulationsaffecting the industry, changes in the demand and price for refrigerants (including unfavorable market conditions adversely affecting the demand for, and theprice of refrigerants), the Company's ability to source refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplieror customer arrangements that become available to the Company in the future, adverse weather conditions, possible technological obsolescence of existingproducts and services, possible reduction in the carrying value of long-lived assets, estimates of the useful life of its assets, potential environmental liability,customer concentration, the ability to obtain financing, any delays or interruptions in bringing products and services to market, the timely availability of anyrequisite permits and authorizations from governmental entities and third parties as well as factors relating to doing business outside the United States,including changes in the laws, regulations, policies, and political, financial and economic conditions, including inflation, interest and currency exchangerates, of countries in which the Company may seek to conduct business, the Company’s ability to successfully integrate any assets it acquires from thirdparties into its operations, and other risks detailed in the this report and in the Company’s other subsequent filings with the Securities and ExchangeCommission (“SEC”).

Past financial performance is no guarantee of future results. Critical Accounting Policies The Company's discussion and analysis of its financial condition and results of operations are based upon its consolidated financial statements, which havebeen prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statementsrequires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure ofcontingent assets and liabilities. Several of the Company's accounting policies involve significant judgments, uncertainties and estimations. The Companybases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of whichform the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under differentassumptions or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on theCompany. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtfulaccounts, inventory reserves, and valuation allowance for the deferred tax assets relating to its net operating loss carry forwards (“NOLs”) and commitmentsand contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical andanticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current andanticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company’s valuationallowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future. Goodwill represents the excess of the purchaseprice over the fair value of the net assets acquired in business combinations accounted for under the purchase method of accounting. The Company tests forany impairment of goodwill annually. Intangibles with determinable lives are amortized over the estimated useful lives of the assets currently ranging from 2to 10 years. The Company reviews these useful lives annually to determine that they reflect future realizable value. The Company utilizes both internal andexternal sources to evaluate potential current and future liabilities for various commitments and contingencies. In the event that the assumptions orconditions change in the future, the estimates could differ from the original estimates. Overview Sales of refrigerants continue to represent a significant portion of the Company’s revenues. The Company’s refrigerant sales are primarily HCFC and HFCbased refrigerants and to a lesser extent CFC based refrigerants that are no longer manufactured. Currently the Company purchases virgin HCFC and HFCrefrigerants and reclaimable HCFC, HFC and CFC refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”)prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants, which production was further limited in January2004. Federal regulations enacted in January 2004 established production and consumption allowances for HCFCs and imposed limitations on theimportation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during theperiod 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In April 2013 the EPA published a finalrule providing for the production or importation of 63 million and 51 million pounds of HCFC-22 in 2013 and 2014, respectively. In October 2014, the EPApublished the Final Rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through2019. In the Final Rule, the EPA has established a linear annual phase down schedule for the production or importation of virgin HCFC-22 that started atapproximately 22 million pounds in 2015 and is being reduced by approximately 4.5 million pounds each year and ends at zero in 2020. The Company has created and developed a service offering known as RefrigerantSide® Services. RefrigerantSide® Services are sold to contractors and end-users whose refrigeration systems are used in commercial air conditioning and industrial processing. These services are offered in addition to refrigerant salesand the Company's traditional refrigerant management services, which consist primarily of reclamation of refrigerants. The Company has created a network ofservice depots that provide a full range of the Company's RefrigerantSide® Services to facilitate the growth and development of its service offerings. The Company focuses its sales and marketing efforts for its RefrigerantSide® Services on customers who the Company believes most readily appreciate andunderstand the value that is provided by its RefrigerantSide® Services offering. In pursuing its sales and marketing strategy, the Company offers itsRefrigerantSide® Services to customers in the following industries: petrochemical, pharmaceutical, industrial power, manufacturing, commercial facility andproperty management and maritime. The Company may incur additional expenses as it further develops and markets its RefrigerantSide® Services offering. 14 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The increase in revenues was attributable to an increase in refrigerant revenues of $24,694,000 offset in part by a decrease in RefrigerantSide®Services revenues of $782,000. The increase in refrigerant revenue is related to both an increase in the selling price per pound of certain refrigerants sold,which accounted for an increase in revenues of $17,374,000, as well as an increase in the number of pounds of certain refrigerants sold, which accounted foran increase in revenues of $7,320,000. The decrease in RefrigerantSide® Services was primarily attributable to a decrease in the price of jobs completed whencompared to the same period in 2014. Cost of sales for the year ended December 31, 2015 was $61,233,000 or 77% of sales. Cost of sales for year ended December 31, 2014 was $49,364,000, or88% of sales. The decrease in the cost of sales percentage, from 88% in 2014 to 77% in 2015, is related to the increase in the selling price per pound ofrefrigerants, as described in the revenue discussion above. Operating expenses for the year ended December 31, 2015 were $10,308,000, an increase of $2,877,000 from the $7,431,000 reported during the comparable2014 period. The increase in operating expenses is primarily attributable to payroll expenses of $2,400,000 of which approximately $1,100,000 is associatedwith payroll for the recent acquisitions completed in late 2014 and early 2015 as well as approximately $500,000 of amortization of intangibles associatedwith these same recent acquisitions. Other income (expense) for the year ended December 31, 2015 was ($474,000), compared to the ($641,000) reported during the comparable 2014 period.Other income (expense) consists of interest expense of $776,000 and $641,000 for the comparable 2015 and 2014 periods, respectively. The increase ininterest expense is due to increased borrowing on the PNC credit facility. Additionally, other income (expense) includes other income of $302,000 in 2015related to the 2015 acquisition earn out that was less than the total amount that had been recorded as part of the purchase price accounting for the acquisitionof a supplier of refrigerants and compressed gases. Income tax expense for the year ended December 31, 2015 was $2,944,000 compared to an income tax benefit of $906,000 reported during the comparable2014 period. For 2015 the income tax expense of $2,944,000 was for federal and state income tax at statutory rates applied to the pre-tax income. For 2014the income tax benefit of $906,000 was for federal and state income tax at statutory rates applied to the pre-tax loss, as well as state income tax refunds for2013 that had not been accrued in 2013. Net income for the year ended December 31, 2015 was $4,763,000, an increase of $5,483,000 from $720,000 net loss reported during the comparable 2014period, primarily due to the increase in revenue and gross profit partially offset by increases in operating expenses, interest expense and income tax expense. Liquidity and Capital Resources At December 31, 2015, the Company had working capital, which represents current assets less current liabilities of $38,509,000, an increase of $6,395,000from the working capital of $32,114,000 at December 31, 2014. The increase in working capital is primarily attributable to the net income for 2015. Inventory and trade receivables are principal components of current assets. At December 31, 2015, the Company had inventories of $61,897,000, an increaseof $24,880,000 from $37,017,000 at December 31, 2014. The increase in the inventory balance is primarily due to the increase in the cost of refrigerants, aswell as the timing and availability of inventory purchases and the sale of refrigerants. The Company's ability to sell and replace its inventory on a timelybasis and the prices at which it can be sold are subject, among other things, to current market conditions and the nature of supplier or customer arrangementsand the Company's ability to source CFC based refrigerants (which are no longer being produced), HCFC refrigerants (which are currently being phased downleading to a full phase out of virgin production), or non-CFC based refrigerants. At December 31, 2015, the Company had trade receivables, net of allowancefor doubtful accounts, of $4,414,000, an increase of $446,000 from $3,968,000 at December 31, 2014. The Company's trade receivables are concentrated withvarious wholesalers, brokers, contractors and end-users within the refrigeration industry that are primarily located in the continental United States. The Company has historically financed its working capital requirements through cash flows from operations, the issuance of debt and equity securities, andbank borrowings. 15 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Net cash used by operating activities for the 2015 period was primarily attributable to an increase in inventorypartially offset by net income, the utilization of the deferred tax assets, as well as increases in accounts payable and accrued expenses. Net cash used by investing activities for the year ended December 31, 2015, was $3,325,000 compared with net cash used by investing activities of$8,031,000 for the comparable 2014 period. The net cash used by investing activities for the 2015 period was primarily related to the January 2015acquisition as well as investment in general purpose equipment for the Company’s production facilities. The net cash used by investing activities for the2014 period was primarily related to the acquisition of Polar Technologies, as well as investment in general purpose equipment for the Company’sChampaign, Illinois facility. Net cash provided by financing activities for the year ended December 31, 2015, was $14,151,000 compared with net cash provided by financing activities of$6,596,000 for the comparable 2014 period. The net cash provided by financing activities for the 2015 period was primarily due to increased borrowings onthe PNC credit facility. At December 31, 2015, the Company had cash and cash equivalents of $1,258,000. The Company continues to assess its capital expenditure needs. TheCompany may, to the extent necessary, continue to utilize its cash balances to purchase equipment primarily for its operations. The Company estimates thatthe total capital expenditures for 2016 will be approximately $1,750,000. The following is a summary of the Company's significant contractual cash obligations for the periods indicated that existed as of December 31, 2015 (in000’s): Twelve Month Period Ended December 31, Long and short term debt and capital leaseobligations: 2016 2017 2018 2019 2020 Total Principal $20,573 $184 $4,077 $30 $2 $24,866 Estimated interest (1) 750 737 368 0 0 1,855 Operating leases 1,297 1,085 421 165 150 3,118 Acquisition earn out /License payable 1,568 333 0 0 0 1,901 Total contractual cash obligations $24,188 $2,339 $4,866 $195 $152 $31,740 (1) The estimated future interest payments on all debt other than revolving debt are based on the respective interest rates applied to the declining principalbalances on each of the notes. On June 22, 2012, a subsidiary of Hudson entered into a Revolving Credit, Term Loan and Security Agreement (the “PNC Facility”) with PNC Bank,National Association, as agent (“Agent” or “PNC”), and such other lenders as may thereafter become a party to the PNC Facility. Under the terms of the PNCFacility, as amended by the First Amendment to the PNC Facility, dated February 15, 2013, Hudson may borrow up to a maximum of $40,000,000 consistingof a term loan in the principal amount of $4,000,000 and revolving loans in a maximum amount up to $36,000,000. Amounts borrowed under the PNCFacility may be used by Hudson for working capital needs and to reimburse drawings under letters of credit. Fees and expenses relating to the creation of thePNC Facility of approximately $38,000 are being amortized over the life of the loan. At December 31, 2015, total borrowings under the PNC Facility wereapproximately $24,227,000, and there was approximately $15,773,000 available to borrow under the revolving line of credit. The effective interest rateunder the PNC Facility was 3.75% at December 31, 2015. Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as setforth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar Rate (as defined in the PNC Facility)or, for Eurodollar Rate Loans (as defined in the PNC Facility) with an interest period in excess of three months, at the earlier of (a) each three months from thecommencement of such Eurodollar Rate Loan or (b) the end of the interest period. Interest charges with respect to loans are computed on the actual principalamount of loans outstanding during the month at a rate per annum equal to (A) with respect to Domestic Rate Loans (as defined in the PNC Facility), the sumof the Alternate Base Rate (as defined in the PNC Facility) plus one half of one percent (.50%) and (B) with respect to Eurodollar Rate Loans, the sum of theEurodollar Rate plus two and one quarter of one percent (2.25%). Hudson granted to PNC, for itself, and as agent for such other lenders as may thereafter become a lender under the PNC Facility, a security interest inHudson’s receivables, intellectual property, general intangibles, inventory and certain other assets. 16 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. The PNC Facility contains certain financial and non-financial covenants relating to Hudson, including limitations on Hudson’s ability to pay dividends oncommon stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties,covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts,impairments to guarantees and a change of control. The PNC Facility contains a financial covenant to maintain at all times a Fixed Charge Coverage Ratio ofnot less than 1.10 to 1.00, tested quarterly on a rolling twelve month basis. Fixed Charge Coverage Ratio is defined in the PNC Facility, with respect to anyfiscal period, as the ratio of (a) EBITDA of Hudson for such period, minus unfinanced capital expenditures (as defined in the PNC Facility) made by Hudsonduring such period, minus the aggregate amount of cash taxes paid by Hudson during such period, minus the aggregate amount of dividends anddistributions made by Hudson during such period, minus the aggregate amount of payments made with cash by Hudson to satisfy soil sampling andreclamation related to environmental cleanup at the Company’s former Hillburn, NY facility during such period (to the extent not already included in thecalculation of EBITDA as determined by the Agent) to (b) the aggregate amount of all principal payments due and/or made, except principal paymentsrelated to outstanding revolving advances with regard to all funded debt (as defined in the PNC Facility) of Hudson during such period, plus the aggregateinterest expense of Hudson during such period. EBITDA as defined in the PNC Facility shall mean for any period the sum of (i) earnings before interest andtaxes for such period plus (ii) depreciation expenses for such period, plus (iii) amortization expenses for such period, plus (iv) non-cash charges. On October 25, 2013, the Company entered into the Second Amendment to the PNC facility (the “Second PNC Amendment”) which, among other things,waived the requirement to comply with the minimum fixed charge coverage ratio covenant of 1.10 to 1.00 for the fiscal quarter ended September 30, 2013,under the PNC Facility, and suspended the minimum fixed charge ratio covenant until the quarterly period ended March 31, 2015. On July 2, 2014, the Company entered into the Third Amendment to the PNC Facility (the “Third PNC Amendment”) which, among other things, extendedthe term of PNC Facility. Pursuant to the Third PNC Amendment, which was effective June 30, 2014, the Termination Date of the PNC Facility (as defined inthe PNC Facility) has been extended to June 30, 2018. On July 1, 2015, the Company entered into the Fourth Amendment to the PNC Facility (the “Fourth PNC Amendment”). The Fourth PNC Amendmentredefined the “Revolving Interest Rate” as well as the “Term Loan Rate” (as defined in the PNC Facility) as follows: “Revolving Interest Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate (as defined in the PNC Facility) plus one halfof one percent (.50%) with respect to Domestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and one quarter of one percent (2.25%) withrespect to the Eurodollar Rate Loans. “Term Loan Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate plus one half of one percent (.50%) with respect to theDomestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and one quarter of one percent (2.25%) with respect to Eurodollar Rate Loans. The Company was in compliance with all covenants, as amended, under the PNC Facility as of December 31, 2015. The Company’s ability to comply withthese covenants in future quarters may be affected by events beyond the Company’s control, including general economic conditions, weather conditions,regulations and refrigerant pricing. Although we expect to remain in compliance with all covenants in the PNC Facility, as amended, depending on our futureoperating performance and general economic conditions, we cannot make any assurance that we will continue to be in compliance. The commitments under the PNC Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, aredue and payable in full on June 30, 2018, unless the commitments are terminated for any reason or the outstanding principal amount of the loans areaccelerated sooner following an event of default. On June 6, 2014 the Company entered into an Underwriting Agreement with an investment banking firm for itself and as representative for two otherinvestment banking firms (collectively, the “Underwriters”), in connection with an underwritten offering (the “Offering”) of 6,000,000 shares of theCompany’s common stock, par value $0.01 per share (the “Firm Shares”). Pursuant to the Underwriting Agreement, the Company agreed to sell to theUnderwriters, and the Underwriters agreed to purchase from the Company, an aggregate of 6,000,000 shares of common stock at a price of $2.3375 per share,and the price to the public was $2.50 per share. Pursuant to the Underwriting Agreement, the Company also granted the Underwriters a 30 day option topurchase up to 900,000 additional shares of its common stock to cover over-allotments, if any. The Company also agreed to reimburse certain expensesincurred by the Underwriters in the Offering. The closing of the Offering was held on June 11, 2014, at which time the Company sold 6,900,000 shares of its common stock to the Underwriters (including900,000 shares to cover over-allotments) at a price of $2.3375 per share, and received gross proceeds of $16,128,750. The Underwriters receivedreimbursement of expenses of $150,000, and the Company also incurred approximately $400,000 of additional expenses in connection with the Offering. The Company believes that it will be able to satisfy its working capital requirements for the foreseeable future from anticipated cash flows from operationsand available funds under the PNC Facility. In addition, the proceeds from the Offering may be used for working capital and general corporate purposeswhich may include, among other things, funding additional acquisitions, although we have no present commitments or agreements with respect to any suchtransactions. Any unanticipated expenses, including, but not limited to, an increase in the cost of refrigerants purchased by the Company, an increase inoperating expenses or failure to achieve expected revenues from the Company's RefrigerantSide® Services and/or refrigerant sales or additional expansion oracquisition costs that may arise in the future would adversely affect the Company's future capital needs. There can be no assurance that the Company'sproposed or future plans will be successful, and as such, the Company may require additional capital sooner than anticipated, which capital may not beavailable on acceptable terms, or at all. 17 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Reliance on Suppliers and Customers The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results.Currently the Company purchases virgin HCFC and HFC refrigerants and reclaimable, primarily HCFC and CFC, refrigerants from suppliers and itscustomers. Under the Act the phase-down of future production of certain virgin HCFC refrigerants commenced in 2010 and is scheduled to be fully phasedout by the year 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by the year 2030. To the extent that the Company isunable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demandand/or price for refrigerants sold by it, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect onthe Company’s operating results and financial position. For the year ended December 31, 2015, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 33% of the Company’s revenues. At December 31, 2015, there were no outstanding receivables from these customers. For the year ended December 31, 2014, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 25% of the Company’s revenues. At December 31, 2014, there were $688,000 in outstanding receivables from these customers. The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company's products or services by any suchcustomer could have a material adverse effect on the Company's operating results and financial position. Seasonality and Weather Conditions and Fluctuations in Operating Results The Company's operating results vary from period to period as a result of weather conditions, requirements of potential customers, non-recurring refrigerantand service sales, availability and price of refrigerant products (virgin or reclaimable), changes in reclamation technology and regulations, timing inintroduction and/or retrofit or replacement of refrigeration equipment, the rate of expansion of the Company's operations, and by other factors. TheCompany's business is seasonal in nature with peak sales of refrigerants occurring in the first half of each year. During past years, the seasonal decrease insales of refrigerants has resulted in losses particularly in the fourth quarter of the year. In addition, to the extent that there is unseasonably cool weatherthroughout the spring and summer months, which would adversely affect the demand for refrigerants, there would be a corresponding negative impact on theCompany. Delays or inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, decliningrefrigerant prices and a loss of a principal customer could result in significant losses. There can be no assurance that the foregoing factors will not occur andresult in a material adverse effect on the Company's financial position and significant losses. The Company believes that to a lesser extent there is a similarseasonal element to RefrigerantSide® Service revenues as refrigerant sales. The Company is continuing to assess its RefrigerantSide® Service revenuesseasonal trend. Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The core principle of ASU 2014-09 is that an entityshould recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entityexpects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify thecontract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price tothe performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also specifiesthe accounting for some costs to obtain or fulfill a contract with a customer. The new standard also will result in enhanced disclosures about revenue, provideguidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improveguidance for multiple-element arrangements. For a public entity, the amendments in this Update are effective for annual reporting periods beginning afterDecember 15, 2017, including interim periods within that reporting period. Early application is not permitted. An entity should apply the amendments inASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09recognized at the date of initial application. The Company is currently evaluating the effects of ASU 2014-09 and therefore cannot estimate the effects, ifany, on historical or future revenue recognition at this time. 18 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs.”ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carryingamount of that debt liability, consistent with debt discounts. For public business entities, the amendments in ASU 2015-03 are effective for financialstatements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, with early adoption permitted for financialstatements that have not been previously issued. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of eachindividual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required tocomply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change inaccounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the changeon the financial statement line items (that is, debt issuance cost asset and the debt liability). The adoption of ASU 2015-03 will have no impact on theCompany’s results of operations and an immaterial impact on the consolidated Balance Sheets. In September 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2015-16, Business Combinations (Topic805): Simplifying the Accounting for Measurement-Period Adjustments, or ASU 2015-16. This amendment requires the acquirer in a business combination torecognize in the reporting period in which adjustment amounts are determined, any adjustments to provisional amounts that are identified during themeasurement period, calculated as if the accounting had been completed at the acquisition date. Prior to the issuance of ASU 2015-16, an acquirer wasrequired to restate prior period financial statements as of the acquisition date for adjustments to provisional amounts. The amendments in ASU 2015-16 are tobe applied prospectively upon adoption. The Company adopted ASU 2015-16 in the fourth quarter of 2015. The adoption of the provisions of ASU 2015-16did not have a material impact on its results of operations or financial position. In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 requires thatdeferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in ASU 2015-17 apply to allentities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component ofan entity be offset and presented as a single amount is not affected. For public business entities, the amendments in ASU 2015-17 are effective for financialstatements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted forall entities as of the beginning of an interim or annual reporting period. Under ASU 2016-02, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-useasset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make anaccounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognizelease expense for such leases generally on a straight-line basis over the lease term. For finance leases, a lessee is required to do the following: 1. Recognize a right-of-use asset and a lease liability, initially measured at the present value of thelease payments, in the statement of financial position; 2. Recognize interest on the lease liability separately from amortization of the right-of-use asset in thestatement of comprehensive income; and 3. Classify repayments of the principal portion of the lease liability within financing activities and payments ofinterest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to do the following:1. Recognize a right-of-use asset and a lease liability, initially measured at the present value ofthe lease payments, in the statement of financial position; 2. Recognize a single lease cost, calculated so that the cost of the lease is allocated over the leaseterm on a generally straight-line basis; and 3. Classify all cash payments within operating activities in the statement of cash flows. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospectiveapproach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practicalexpedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commencedbefore the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. Anentity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance withprevious GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases ateach reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlyapplication of the amendments in this Update is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on itsconsolidated financial statements. 19 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Quantitative and Qualitative Disclosures about Market Risk Interest Rate Sensitivity We are exposed to market risk from fluctuations in interest rates on the PNC Facility. The PNC Facility is a $40,000,000 secured facility. Interest on loansunder the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as set forth in the PNCFacility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar rate (as set forth in the PNC Facility) or, for Eurodollarrate loans with an interest period in excess of three months, at the earlier of (a) each three months from the commencement of such Eurodollar rate loan or (b)the end if he interest period. As of December 31, 2015 interest charges with respect to loans are computed on the actual principal amount of loans outstandingduring the month at a rate per annum equal to (A) with respect to Domestic Rate Loans (as defined in the PNC Facility), the sum of the Alternate Base Rate (asdefined in the PNC Facility) plus one half of one percent (.50%) and (B) with respect to Eurodollar Rate Loans, the sum of the Eurodollar Rate plus two andone quarter of one percent (2.25%). The outstanding balance on the PNC Facility as of December 31, 2015 was $24,227,000. Future interest rate changes onour borrowing under the PNC Facility may have an impact on our consolidated results of operations. Refrigerant Market We are also exposed to market risk from fluctuations in the demand, price and availability of refrigerants. To the extent that the Company is unable to sourcesufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms, or experiences a decline in demand and/or price forrefrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales or write downs of inventory, which could have amaterial adverse effect on our consolidated results of operations. Item 8. Financial Statements and Supplementary Data The financial statements appear in a separate section of this report following Part IV. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure Not Applicable Item 9A. Controls and Procedures Disclosure Controls and Procedures The Company, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and ChiefFinancial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) of the SecuritiesExchange Act of 1934, as amended (“Exchange Act”), as of the end of the period covered by this report. Based on that evaluation, the Chief ExecutiveOfficer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective and provided reasonableassurance that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the timeperiods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to theCompany’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding requireddisclosure. Because of the inherent limitations in all control systems, any controls and procedures, no matter how well designed and operated, can provideonly reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Furthermore, the Company’s controls and procedures can be circumvented by the individual acts ofsome persons, by collusion of two or more people or by management override of the control and misstatements due to error or fraud may occur and not bedetected on a timely basis. Changes in Internal Control over Financial Reporting There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarterended December 31, 2015 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. 20 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The Company’s internal control over financial reporting is designed to provide reasonable assurance to theCompany’s management and board of directors regarding the preparation and fair presentation of published financial statements and the reliability offinancial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systemsdetermined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The Company’s Chief Executive Officer and Chief Financial Officer have assessed the effectiveness of the Company’s internal control over financialreporting as of December 31, 2015. In making this assessment, the Company’s Chief Executive Officer and Chief Financial Officer have used the criteria setforth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control – Integrated Framework (2013). Based onour assessment, the Company’s Chief Executive Officer and Chief Financial Officer believe that, as of December 31, 2015, the Company’s internal controlover financial reporting is effective based on those criteria. BDO USA, LLP, the independent registered public accounting firm which audits our financial statements, has audited our internal control over financialreporting as of December 31, 2015 and has expressed an unqualified opinion thereon. 21 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all materialrespects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, andtesting and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such otherprocedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate. In our opinion, Hudson Technologies Inc. and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as ofDecember 31, 2015, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheetsof Hudson Technologies Inc. and Subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of operations, stockholders’equity, and cash flows for the years then ended and our report dated March 11, 2016 expressed an unqualified opinion thereon.

In the case of restricted stock, deferred stock or other stock-based awards, the Committee, within the limitations of the 2014 Plan, determines the persons to whom awards will be granted, the number of shares of stocksubject to the award, and the restrictions on issuance and transfer of such shares. Unless the 2014 Plan is sooner terminated, the ability to grant options orother awards under the 2014 Plan will expire on September 17, 2024. ISOs granted under the 2014 Plan may not be granted at a price less than the fair market value of our common stock on the date of grant (or 110% of fairmarket value in the case of ISO’s granted to a 10% shareholder). In the case of ISOs, the aggregate fair market value of shares for which ISOs granted to anyemployee are exercisable for the first time by such employee during any calendar year (under all of our stock option plans) may not exceed $100,000. Non-qualified options granted under the 2014 Plan may not be granted at a price less than the fair market value of our common stock. Options granted under the2014 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% shareholder). Except as otherwiseprovided by the Committee with respect to non-qualified options, all options, restricted stock, deferred stock or other stock-based awards granted under the2014 Plan are not transferable during a grantee’s lifetime but are transferable at death by will or by the laws of descent and distribution. In general, upontermination of employment of a grantee, all options, restricted stock, deferred stock or other stock-based awards granted to such person which are notexercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination ofemployment. As of December 31, 2015, no options have been issued under the 2014 Plan and 3,000,000 shares are reserved for future issuances under the 2014 Plan.

The Company’s operations consist of one reportable segment. The Company's products and servicesare primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerantmanagement services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer's site, consisting of systemdecontamination to remove moisture, oils and other contaminants. In addition, the Company’s SmartEnergy OPSTM service is a web-based real timecontinuous monitoring service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and ChillSmart® services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also participatesin the generation of carbon offset projects. The Company operates principally through its wholly-owned subsidiary, Hudson Technologies Company. Unlessthe context requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and itssubsidiaries. In preparing the accompanying consolidated financial statements, and in accordance with ASC855-10 “Subsequent Events”, the Company’s management hasevaluated subsequent events through the date that the financial statements were filed. In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments werenormal and recurring. Consolidation The consolidated financial statements represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls.Significant intercompany accounts and transactions have been eliminated. The Company's consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc. and Hudson Technologies Company. The Company does not present a statement of comprehensive income as itscomprehensive income is the same as its net income. Fair Value of Financial Instruments The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at December 31, 2015 andDecember 31, 2014, because of the relatively short maturity of these instruments. The carrying value of short and long-term debt approximates fair value, dueto the variable rate nature of the debt, as of December 31, 2015 and December 31, 2014. Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and tradeaccounts receivable. The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDICinsurance coverage. The Company's trade accounts receivable are primarily due from companies throughout the United States. The Company reviews eachcustomer's credit history before extending credit. The Company establishes an allowance for doubtful accounts based on factors associated with the credit risk of specific accounts, historical trends, and otherinformation. The carrying value of the Company’s accounts receivable is reduced by the established allowance for doubtful accounts. The allowance fordoubtful accounts includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accountsreceivable balances. The Company adjusts its reserves based on factors that affect the collectability of the accounts receivable balances. For the year ended December 31, 2015, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 33% of the Company’s revenues. At December 31, 2015, there were no outstanding receivables from these customers. For the year ended December 31, 2014, two customers each accounted for 10% or more of the Company’s revenues and, in the aggregate these two customersaccounted for 25% of the Company’s revenues. At December 31, 2014, there were $688,000 in outstanding receivables from these customers. 43 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company's products or services by any suchcustomer could have a material adverse effect on the Company's operating results and financial position. Cash and Cash Equivalents Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents. Inventories Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or market. Where themarket price of inventory is less than the related cost, the Company may be required to write down its inventory through a lower of cost or market adjustment,the impact of which would be reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment would be based on management’sjudgment regarding future demand and market conditions and analysis of historical experience. Property, Plant and Equipment Property, plant and equipment are stated at cost, including internally manufactured equipment. The cost to complete equipment that is under construction isnot considered to be material to the Company's financial position. Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets. Leasehold improvements are amortized on a straight-line basis over the shorter of economic life orterms of the respective leases. Costs of maintenance and repairs are charged to expense when incurred. Due to the specialized nature of the Company's business, it is possible that the Company's estimates of equipment useful life periods may change in thefuture. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchasemethod of accounting. The Company performed the annual goodwill impairment assessment using a qualitative approach to determine whether it is morelikely than not that the fair value of goodwill is less than its carrying value. In performing the qualitative assessment, we identify and consider thesignificance of relevant key factors, events, and circumstances that affect the fair value of our goodwill. These factors include external factors such asmacroeconomic, industry, and market conditions, as well as entity-specific factors, such as our actual and planned financial performance. If the results of thequalitative assessment conclude that it is not more likely than not that the fair value of goodwill exceeds its carrying value, additional quantitativeimpairment testing is performed. Revenues and Cost of Sales Revenues are recorded upon completion of service or product shipment and passage of title to customers in accordance with contractual terms. The Companyevaluates each sale to ensure collectability. In addition, each sale is based on an arrangement with the customer and the sales price to the customer is fixed.License fees are recognized over the period of the license based on the respective performance measurements associated with the license. Royalty revenuesare recognized when earned. Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of theCompany's facilities. To the extent that the Company charges its customers shipping fees, such amounts are included as a component of revenue and thecorresponding costs are included as a component of cost of sales. The Company's revenues are derived from refrigerant and reclamation sales and RefrigerantSide® Services, including license and royalty revenues. Therevenues for each of these lines are as follows: Years Ended December 31, 2015 2014 (in thousands) Refrigerant and reclamation sales $75,154 $50,460 RefrigerantSide® Services 4,568 5,350 Total $79,722 $55,810 Income Taxes The Company utilizes the asset and liability method for recording deferred income taxes, which provides for the establishment of deferred tax asset orliability accounts based on the difference between tax and financial reporting bases of certain assets and liabilities. The tax benefit associated with theCompany's net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company is expected to recognize future taxable income. TheCompany assesses the recoverability of its deferred tax assets based on its expectation that it will recognize future taxable income and adjusts its valuationallowance accordingly. As of December 31, 2015 and 2014, the net deferred tax asset was $3,663,000 and $6,428,000, respectively. 44 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Certain states either do not allow or limit NOLs and as such the Company will be liable for certain state taxes. To the extent that the Company utilizes itsNOLs, it will not pay tax on such income but may be subject to the federal alternative minimum tax. In addition, to the extent that the Company’s netincome, if any, exceeds the annual NOL limitation it will pay income taxes based on existing statutory rates. Moreover, as a result of a “change in control”, asdefined by the Internal Revenue Service, the Company’s ability to utilize its existing NOLs is subject to certain annual limitations. Approximately$6,750,000 of the Company’s $9,000,000 of NOLs are subject to annual limitations of $1,300,000. As a result of an Internal Revenue Service audit, the 2013 and prior federal tax years have been closed. The Company operates in many states throughout theUnited States and, as of December 31, 2015, the various states’ statutes of limitations remain open for tax years subsequent to 2009. The Company recognizesinterest and penalties, if any, relating to income taxes as a component of the provision for income taxes. The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by the taxingauthorities. As of December 31, 2015 and 2014, the Company had no uncertain tax positions. Income per Common and Equivalent Shares If dilutive, common equivalent shares (common shares assuming exercise of options and warrants) utilizing the treasury stock method are considered in thepresentation of diluted earnings per share. The reconciliation of shares used to determine net income per share is as follows (dollars in thousands): Years ended December 31, 2015 2014 Net income (loss) $4,763 $(720) Weighted average number of shares - basic 32,546,840 29,122,746 Shares underlying warrants 300,846 0 Shares underlying options 1,088,413 0 Weighted average number of shares outstanding - diluted 33,936,099 29,122,746 During the years ended December 31, 2015 and 2014, certain options and warrants aggregating 106,290 and 4,449,624 shares, respectively, have beenexcluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive. Estimates and Risks The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to makeestimates and assumptions that affect reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the results ofoperations during the reporting period. Actual results could differ from these estimates. The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies. Inthe event that the assumptions or conditions change in the future, the estimates could differ from the original estimates. Several of the Company's accounting policies involve significant judgments, uncertainties and estimations. The Company bases its estimates on historicalexperience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for makingjudgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To theextent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis,the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, andvaluation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Companyestimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer tofulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventoryto net realizable value is necessary. In determining the Company’s valuation allowance for its deferred tax assets, the Company assesses its ability to generatetaxable income in the future. 45 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited theproduction of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the productionof virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants whichimposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to bephased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In April 2013, theEnvironmental Protection Agency (“EPA”) published a final rule providing for the production or importation of 63 million and 51 million pounds of HCFC-22 in 2013 and 2014, respectively. In October 2014, the EPA published a final rule providing further reductions in the production and consumptionallowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA has established a linear draw down forthe production or importation of virgin HCFC-22 that started at approximately 22 million pounds in 2015 and reduces by approximately 4.5 million poundseach year and ends at zero in 2020. To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms orexperiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales,which could have a material adverse effect on its operating results and its financial position. The Company is subject to various legal proceedings. The Company assesses the merit and potential liability associated with each of these proceedings. Inaddition, the Company estimates potential liability, if any, related to these matters. To the extent that these estimates are not accurate, or circumstanceschange in the future, the Company could realize liabilities, which could have a material adverse effect on its operating results and its financial position. Impairment of Long-lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not berecoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flowsexpected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which thecarrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less thecost to sell. Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The core principle of ASU 2014-09 is that an entityshould recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entityexpects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify thecontract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price tothe performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also specifiesthe accounting for some costs to obtain or fulfill a contract with a customer. The new standard also will result in enhanced disclosures about revenue, provideguidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improveguidance for multiple-element arrangements. For a public entity, the amendments in this Update are effective for annual reporting periods beginning afterDecember 15, 2017, including interim periods within that reporting period. Early application is not permitted. An entity should apply the amendments inASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09recognized at the date of initial application. The Company is currently evaluating the effects of ASU 2014-09 and therefore cannot estimate the effects, ifany, on historical or future revenue recognition at this time. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs.”ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carryingamount of that debt liability, consistent with debt discounts. For public business entities, the amendments in ASU 2015-03 are effective for financialstatements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, with early adoption permitted for financialstatements that have not been previously issued. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of eachindividual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required tocomply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change inaccounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the changeon the financial statement line items (that is, debt issuance cost asset and the debt liability). The adoption of ASU 2015-03 will have no impact on theCompany’s results of operations and an immaterial impact on the Company’s Balance Sheets. 46 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

This amendment requires the acquirer in a business combination torecognize in the reporting period in which adjustment amounts are determined, any adjustments to provisional amounts that are identified during themeasurement period, calculated as if the accounting had been completed at the acquisition date. Prior to the issuance of ASU 2015-16, an acquirer wasrequired to restate prior period financial statements as of the acquisition date for adjustments to provisional amounts. The amendments in ASU 2015-16 are tobe applied prospectively upon adoption. The Company adopted ASU 2015-16 in the fourth quarter of 2015. The adoption of the provisions of ASU 2015-16did not have a material impact on its results of operations or financial position. In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 requires thatdeferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in ASU 2015-17 apply to allentities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component ofan entity be offset and presented as a single amount is not affected. For public business entities, the amendments in ASU 2015-17 are effective for financialstatements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted forall entities as of the beginning of an interim or annual reporting period. Under ASU 2016-02, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-useasset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make anaccounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognizelease expense for such leases generally on a straight-line basis over the lease term. For finance leases, a lessee is required to do the following: 1. Recognize a right-of-use asset and a lease liability, initially measured at the present value of thelease payments, in the statement of financial position; 2. Recognize interest on the lease liability separately from amortization of the right-of-use asset in thestatement of comprehensive income; and3. Classify repayments of the principal portion of the lease liability within financing activities and payments ofinterest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to do the following:1. Recognize a right-of-use asset and a lease liability, initially measured at the present value ofthe lease payments, in the statement of financial position; 2. Recognize a single lease cost, calculated so that the cost of the lease is allocated over the leaseterm on a generally straight-line basis; and 3. Classify all cash payments within operating activities in the statement of cash flows. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospectiveapproach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practicalexpedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commencedbefore the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. Anentity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance withprevious GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases ateach reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlyapplication of the amendments in this Update is permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on itsconsolidated financial statements. 47 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The income tax expense(benefit) for each of the years ended December 31, 2015 and 2014 were for federal and state income tax at statutory rates applied to the pre-tax income (loss)for each of the periods. The following summarizes the (benefit) / provision for income taxes: Years Ended December 31, 2015 2014 (in thousands) Current: Federal $174 $0 State and local 2 (49) 176 (49)Deferred: Federal 2,460 (767)State and local 308 (90) 2,768 (857)Expense (benefit) for income taxes $2,944 $(906) Reconciliation of the Company's actual tax rate to the U.S. Federal statutory rate is as follows: Years ended December 31, 2015 2014 Income tax rates - Statutory U.S. federal rate 34% 34%- States, net U.S. benefits 4% 4%- Tax benefit from prior year 0% 18%Total 38% 56% As of December 31, 2015, the Company had NOL's of approximately $9,000,000 expiring through 2034. Approximately $6,750,000 of the Company’s$9,000,000 of NOL’s are subject to annual limitations of $1,300,000. Elements of deferred income tax assets (liabilities) are as follows: December 31, 2015 2014 (in thousands) Deferred tax assets (liabilities) - Depreciation & amortization $(412) $(428)- Reserves for doubtful accounts 127 92 - Inventory reserve 250 305 - Non qualified stock options 108 215 - NOL 3,430 6,244 - AMT credit carryforward 160 0 Total $3,663 $6,428 The Company considered its projected future taxable income, and associated annual limitations, in determining the amount of deferred tax assets torecognize. The Company believes that given the extended time period that it may recognize its deferred tax assets, it is more likely than not it will realize thebenefit of these assets prior to their expiration. Note 3 - Trade accounts receivable - net At December 31, 2015 and 2014, trade accounts receivable are net of reserves for doubtful accounts of $335,000 and $244,000, respectively. 48 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Note 6 – Goodwill and intangible assets Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchasemethod of accounting. The Company performed the annual goodwill impairment assessment using a qualitative approach to determine whether it is morelikely than not that the fair value of goodwill is less than its carrying value. In performing the qualitative assessment, we identify and consider thesignificance of relevant key factors, events, and circumstances that affect the fair value of our goodwill. These factors include external factors such asmacroeconomic, industry, and market conditions, as well as entity-specific factors, such as our actual and planned financial performance. If the results of thequalitative assessment conclude that it is not more likely than not that the fair value of goodwill exceeds its carrying value, additional quantitativeimpairment testing is performed. The impairment test was performed at the operating segment level as the acquired businesses have been fully integrated into our existing structure. Based onthe results of the impairment assessment performed, we concluded that it is more likely than not that the fair value of our goodwill significantly exceeds thecarrying value. At December 31, 2015 the Company had $856,000 of goodwill, of which $435,000 is attributable to the acquisition of Polar Technologies, LLC and$421,000 is attributable to the acquisition of a supplier of refrigerants and compressed gases. 49 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Under the terms of the PNCFacility, as amended by the First Amendment to the PNC Facility, dated February 15, 2013, Hudson may borrow up to a maximum of $40,000,000 consistingof a term loan in the principal amount of $4,000,000 and revolving loans in a maximum amount up to $36,000,000. Amounts borrowed under the PNCFacility may be used by Hudson for working capital needs and to reimburse drawings under letters of credit. Fees and expenses relating to the creation of thePNC Facility of approximately $38,000 are being amortized over the life of the loan. At December 31, 2015, total borrowings under the PNC Facility wereapproximately $24,227,000, and there was approximately $15,773,000 available to borrow under the revolving line of credit. The effective interest rateunder the PNC Facility was 3.75% at December 31, 2015. Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as setforth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar Rate (as defined in the PNC Facility)or, for Eurodollar Rate Loans (as defined in the PNC Facility) with an interest period in excess of three months, at the earlier of (a) each three months from thecommencement of such Eurodollar Rate Loan or (b) the end of the interest period. Interest charges with respect to loans are computed on the actual principalamount of loans outstanding during the month at a rate per annum equal to (A) with respect to Domestic Rate Loans (as defined in the PNC Facility), the sumof the Alternate Base Rate (as defined in the PNC Facility) plus one half of one percent (.50%) and (B) with respect to Eurodollar Rate Loans, the sum of theEurodollar Rate plus two and one quarter of one percent (2.25%). 50 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The PNC Facility contains a financial covenant to maintain at all times a Fixed Charge Coverage Ratio ofnot less than 1.10 to 1.00, tested quarterly on a rolling twelve month basis. Fixed Charge Coverage Ratio is defined in the PNC Facility, with respect to anyfiscal period, as the ratio of (a) EBITDA of Hudson for such period, minus unfinanced capital expenditures (as defined in the PNC Facility) made by Hudsonduring such period, minus the aggregate amount of cash taxes paid by Hudson during such period, minus the aggregate amount of dividends anddistributions made by Hudson during such period, minus the aggregate amount of payments made with cash by Hudson to satisfy soil sampling andreclamation related to environmental cleanup at the Company’s former Hillburn, NY facility during such period (to the extent not already included in thecalculation of EBITDA as determined by the Agent) to (b) the aggregate amount of all principal payments due and/or made, except principal paymentsrelated to outstanding revolving advances with regard to all funded debt (as defined in the PNC Facility) of Hudson during such period, plus the aggregateinterest expense of Hudson during such period. EBITDA as defined in the PNC Facility shall mean for any period the sum of (i) earnings before interest andtaxes for such period plus (ii) depreciation expenses for such period, plus (iii) amortization expenses for such period, plus (iv) non-cash charges. On October 25, 2013, the Company entered into the Second Amendment to the PNC facility (the “Second PNC Amendment”) which, among other things,waived the requirement to comply with the minimum fixed charge coverage ratio covenant of 1.10 to 1.00 for the fiscal quarter ended September 30, 2013,under the PNC Facility, and suspended the minimum fixed charge ratio covenant until the quarterly period ended March 31, 2015. On July 2, 2014, the Company entered into the Third Amendment to the PNC Facility (the “Third PNC Amendment”) which, among other things, extendedthe term of PNC Facility. Pursuant to the Third PNC Amendment, which was effective June 30, 2014, the Termination Date of the PNC Facility (as defined inthe PNC Facility) has been extended to June 30, 2018. On July 1, 2015, the Company entered into the Fourth Amendment to the PNC Facility (the “Fourth PNC Amendment”). The Fourth PNC Amendmentredefined the “Revolving Interest Rate” as well as the “Term Loan Rate” (as defined in the PNC Facility) as follows: “Revolving Interest Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate (as defined in the PNC Facility) plus one halfof one percent (.50%) with respect to Domestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and one quarter of one percent (2.25%) withrespect to the Eurodollar Rate Loans. “Term Loan Rate” shall mean an interest rate per annum equal to (a) the sum of the Alternate Base Rate plus one half of one percent (.50%) with respect to theDomestic Rate Loans and (b) the sum of the Eurodollar Rate plus two and one quarter of one percent (2.25%) with respect to Eurodollar Rate Loans. The Company was in compliance with all covenants, as amended, under the PNC Facility as of December 31, 2015. The Company’s ability to comply withthese covenants in future quarters may be affected by events beyond the Company’s control, including general economic conditions, weather conditions,regulations and refrigerant pricing. Although we expect to remain in compliance with all covenants in the PNC Facility, as amended, depending on our futureoperating performance and general economic conditions, we cannot make any assurance that we will continue to be in compliance. The commitments under the PNC Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, aredue and payable in full on June 30, 2018, unless the commitments are terminated for any reason or the outstanding principal amount of the loans areaccelerated sooner following an event of default. Building and Land Mortgage On June 1, 2012, the Company entered into a mortgage note with Busey Bank for $855,000.

In addition to the properties above, the Company does at times utilize public warehouse space on amonth to month basis. The Company typically enters into short-term leases for the facilities and wherever possible extends the expiration date of such leases. Future commitments under operating leases are summarized as follows: Years ended December 31, Amount (in thousands) -2016 $1,297 -2017 1,085 -2018 421 -2019 165 -2020 150 Total $3,118 Legal Proceedings On April 1, 1999, the Company reported a release of approximately 7,800 lbs. of R-11 refrigerant (the “1999 Release”), at its former leased facility inHillburn, NY (the “Hillburn Facility”), which the Company vacated in June 2006. Since September 2000, last modified in March 2013, the Company signed an Order on Consent with the New York State Department of EnvironmentalConservation (“DEC”) whereby the Company agreed to operate a remediation system to reduce R-11 refrigerant levels in the groundwater under and aroundthe Hillburn Facility and agreed to perform periodic testing at the Hillburn Facility until remaining groundwater contamination has been effectively abated.The Company accrued, as an expense in its consolidated financial statements, the costs that the Company believes it will incur in connection with itscompliance with the Order of Consent through December 31, 2018. There can be no assurance that additional testing will not be required or that theCompany will not incur additional costs and such costs in excess of the Company’s estimate may have a material adverse effect on the Company financialcondition or results of operations. The Company has exhausted all insurance proceeds available for the 1999 Release under all applicable policies. In May 2000, the Hillburn facility as a result of the 1999 release, was nominated by EPA for listing on the National Priorities List (“NPL”) pursuant toCERCLA. In September 2003, the EPA advised the Company that it had no current plans to finalize the process for listing of the Hillburn facility on the NPL. 53 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Zugibe, which currently expires in October 2018and is automatically renewable for successive two-year terms unless either party gives notice of termination at least ninety days prior to the then expirationdate of the then current term.

Note 10 - Share-Based Compensation Share-based compensation represents the cost related to share-based awards, typically stock options or stock grants, granted to employees, non-employees,officers and directors. Share-based compensation is measured at grant date, based on the estimated aggregate fair value of the award on the grant date, andsuch amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period. For the years 2015and 2014, the share-based compensation expense of $173,000 and $708,000, respectively, is reflected in general and administrative expenses in theconsolidated Statements of Operations. Share-based awards have historically been made as stock options, and recently during the third quarter 2015 as stock grants, issued pursuant to the terms ofthe Company’s stock option and stock incentive plans, (collectively, the “Plans”), described below. The Plans may be administered by the Board of Directorsor the Compensation Committee of the Board or by another committee appointed by the Board from among its members as provided in the Plans. Presently,the Plans are administered by the Company’s Compensation Committee of the Board of Directors. As of December 31, 2015, the Plans authorized theissuance of stock options to purchase 6,000,000 shares of the Company’s common stock and, as of December 31, 2015 there were 4,439,023 shares of theCompany’s common stock available for issuance for future stock option grants or other stock based awards. Stock option awards, which allow the recipient to purchase shares of the Company’s common stock at a fixed price, are typically granted at an exercise priceequal to the Company’s stock price at the date of grant. Typically, the Company’s stock option awards have vested from immediately to two years from thegrant date and have had a contractual term ranging from three to ten years. During the years 2015 and 2014, the Company issued options to purchase 164,506 shares and 1,055,500 shares, respectively. During the years 2015 and2014, the Company issued stock grants of 9,835 shares and no shares, respectively. As of December 31, 2015 there was $15,000 of unrecognizedcompensation cost related to non-vested previously granted option awards.

All stock options have been granted to employees and non-employees at exercise prices equal to or in excess of the market value on the date of the grant. The Company determines the fair value of share based awards at the grant date by using the Black-Scholes option-pricing model, and is incorporating thesimplified method to compute expected lives of share based awards with the following weighted-average assumptions: Years ended December 31, 2015 2014 Assumptions Dividend yield 0% 0%Risk free interest rate 0.83%-1.03% 1.00%-1.69%Expected volatility 49%-60% 59%-66%Expected lives 3 years 3-5 years A summary of the activity for the Company's Plans for the indicated periods is presented below: Stock Option Plan Totals Shares WeightedAverageExercise Price Outstanding at December 31, 2013 2,517,911 $1.33 -Exercised (292,537) $1.03 -Granted 1,055,500 $3.28 Outstanding at December 31, 2014 3,280,874 $1.98 -Cancelled (132,500) $3.72 -Exercised (679,291) $1.65 -Granted 164,506 $3.28 Outstanding at December 31, 2015 2,633,589 $2.06 The following is the weighted average contractual life in years and the weighted average exercise price at December 31, 2015 of: Weighted Average Number of Remaining Weighted Average Options Contractual Life Exercise Price Options outstanding 2,633,589 2.8 years $2.06 Options vested 2,612,755 2.8 years $2.05 55 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Note 11 - Acquisitions On November 5, 2014 the Company purchased certain assets from Polar Technologies, LLC (“Polar”) related to its refrigerant reclamation business andfacilities in Nashville, Tennessee; Ontario, California, and San Juan, Puerto Rico; hiring approximately thirty-two Polar employees associated with thebusiness. The purchase price for this acquisition was $8,035,000. A portion of the purchase price is to be paid in the future pursuant to the purchaseagreement. The preliminary asset allocation reflected in the December 31, 2014 financial statements was approximately $5,435,000 of tangible assets,approximately $2,335,000 of intangible assets, and approximately $265,000 of goodwill. The intangible assets will be amortized over a period of 2 to 10years. The goodwill recognized as part of the acquisition, is deductible for tax purposes. As of December 31, 2015 the valuation and allocation of the purchase price for Polar has been finalized resulting in an increase in tangible assets of$165,000, as well as an increase in goodwill of $170,000 and a decrease in intangible assets of $335,000. This final valuation has been reflected in theDecember 31, 2015 financial statements. The results of the Polar operations are included in the Company’s consolidated statement of operations from the date of acquisition and are not material tothe Company’s financial position or results of operations. On January 16, 2015, the Company acquired certain assets of a supplier of refrigerants and compressed gases, and also hired three employees associated withthe business. The purchase price for this acquisition was $2,424,000 cash paid at closing and the assumption of a liability of $20,000, and a maximum of anadditional $3,000,000 earn-out. The preliminary asset allocation was approximately $1,606,000 of tangible assets, approximately $1,500,000 of intangibleassets, and approximately $2,338,000 of goodwill. As of December 31, 2015 the valuation and allocation of the purchase price for this acquisition has been finalized. As part of that process it has beendetermined that the earn-out payable that had been previously recorded at the maximum earn out of $3,000,000 per the purchase agreement was overstatedby approximately $1,000,000. This adjustment to the earn-out payable resulted in lowering the purchase price from approximately $5,400,000 toapproximately $4,400,000. The final valuation resulted in a reduction in goodwill by approximately $1,900,000, and increase in intangible assets ofapproximately $800,000 and an increase in current assets of approximately $100,000. This final valuation as well as the respective changes in theamortization of intangibles has been reflected in the December 31, 2015 financial statements. The adjusted earn-out payable of approximately $2,000,000 consists of approximately $1,100,000 for the fiscal year ended December 31, 2015 andapproximately $900,000 for the fiscal year ending December 31, 2016. For the fiscal year ended December 31, 2015 the actual earn-out was approximately$800,000 resulting in a year end adjustment to reduce the payable by approximately $300,000 which has been reflected in the December 31, 2015Statements of Operations as Other Income. As of December 31, 2015 approximately $445,000 of the 2015 earn-out has been paid and the remaining balanceof $371,000 is recorded as a current liability on the December 31, 2015 balance sheet. The earn out payable for the fiscal year ending December 31, 2016 of approximately $900,000 has been recorded in other current liabilities on the December31, 2015 balance sheet. The intangible assets are being amortized over a period ranging from two to ten years. The goodwill recognized as part of the acquisition will be deductiblefor tax purposes. The transaction also provides for additional employee compensation for years 2017 through 2019, based on certain revenue performance.The total additional employee compensation, if any, cannot exceed $3,000,000. The results of the acquired business operations are included in the Company’s consolidated Statements of Operations from the date of acquisition, and are notmaterial to the Company’s financial position or results of operations. Pro Forma Information Pro forma revenues and results of operations as if the businesses had been acquired on January 1, 2014 are not presented, as the acquisition is not material toour financial position or our results of operations. 56 Source: HUDSON TECHNOLOGIES INC /NY, 10-K, March 11, 2016Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.
