Overview

Business Operations

We are a provider of specialty activated carbon technologies, delivering innovative solutions for air and water purification. We provide patented and proprietary technologies for mercury emissions capture to the coal-fired utility sector, and are developing disruptive water purification technologies with a specialization on forever chemicals such as PFAS and PFOS.

Mercury Emissions

We provide mercury capture solutions for coal-fired power plants driven by our patented two-part SEA® process using a powerful combination of science and engineering. Our leading-edge services have been shown to achieve mercury emissions removal at a significantly lower cost and with less operational impact to coal-fired power plants than other used methods, while maintaining and/or increasing power plant output and preserving the marketability of byproducts for beneficial use. We design systems and materials tailored and formulated specifically to each customer's coal-fired units. North America is currently the largest market for our emissions technologies. The market for mercury removal from power plant emissions in the United States have largely been driven by federal regulations. The MATS rule, proposed by the EPA in May 2011 and which became effective in April 2012, is intended to reduce air emissions of heavy metals, including Hg, from all major U.S. power plants burning coal or oil, which are the leading source of non-natural mercury emissions in the U.S. Our mercury removal technologies and systems achieve mercury removal levels which meet or exceed the MATS requirements with lower cost and plant systems impacts than typical PAC or BAC sorbent injection systems. Our products have been shown to be successful across a myriad of fuel and system types, tunable to any configuration, and environmentally friendly, allowing for the recycling of fly ash for beneficial use.

Our SEA® technology provides total mercury control with solutions that are based on a thorough scientific understanding of actual and probable interactions involved in mercury capture in coal-fired flue gas. A complete understanding of the complexity of mercury-sorbent-flue gas interactions and chemisorption mechanisms allows for optimal control strategy and product formulation, resulting in effective mercury capture. Combined with a thorough proprietary audit of the plant and its configuration and instrumentation, we believe our complete science and engineering approach for mercury-sorbent-flue gas interactions are well-understood, highly predictive, and critical to delivering total mercury control.

We believe that a significant percentage of coal-fired power plants in the United States have adopted and are infringing upon our two-part Sorbent Enhancement Additive (SEA®) process for mercury removal from coal-fired power plants.

Beginning in 2019, we began to actively enforce our patent rights against unauthorized use of our patented technologies, and have since initiated patent litigation in various jurisdictions against multiple infringers, claiming infringement of our patents related to our two-part process for mercury removal from coal-fired power plants. We view such litigation as a last resort. Our goal and overall strategy is to convert infringers to our supply chain of sorbent products for mercury removal, or otherwise license our patents to them on a non-exclusive basis in connection with their respective coal-fired power plants.

28

In April 2023, the EPA issued a proposal to strengthen and update MATS. Such proposal was finalized and published in May 2024 with an effective date of July 8, 2024 which, among other things, strengthens and updates MATS for coal-fired power plants and tightens the emission standard for mercury for existing lignite-fired power plants to a level that is aligned with the mercury standard that other coal-fired power plants have been achieving under MATS.

On March 12, 2025, the newly appointed EPA administrator under the Trump Administration announced plans to roll back dozens of environmental regulations including the reconsideration of the MATS regulation. On April 8, 2025, President Trump signed a Proclamation exempting certain stationary sources, identified in Annex 1 of the Proclamation, from compliance with the 2024 updated MATS Rule. As set out in the Proclamation, the President's exemption lasts for a period of two years beyond the updated Rule's compliance date (i.e., for the period beginning July 8, 2027, and concluding July 8, 2029). During the two-year period these stationary sources identified in Annex 1 are subject to the compliance obligations that they are currently subject to under MATS as the MATS Rule existed prior to the 2024 update. Annex 1 identifies 47 plant owners and over 60 power plants provided such exemption, which list includes a number of our customers.

In June 2025, the EPA proposed to repeal certain amendments finalized in 2024 to the MATS Rule and return compliance obligations to the MATS standards which existed prior to the 2024 update. The EPA intends to finalize action on this proposal by December 2025.

Water Treatment

In April 2024, the EPA under the Biden Administration issued the first-ever national, enforceable drinking water standard to protect communities from exposure to harmful PFAS, also known as "forever chemicals". The Rule established legally enforceable MCLs for six PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, and HFPO-DA as contaminants with individual MCLs, and PFAS mixtures containing at least two or more of PFHxS, PFNA, HFPO-DA, and PFBS using a Hazard Index MCL to account for the combined and co-occurring levels of these PFAS in drinking water. Under the Rule, public water systems must monitor these PFAS and must complete initial monitoring by 2027, followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of these PFAS in their drinking water beginning in 2027.

In April 2024, we announced the introduction of our new water treatment business to address the growing potable (drinking) water market with next-generation sorbent technologies. These new solutions are being designed to use significantly less activated carbon, offering a more environmentally sustainable approach to water treatment while maintaining or improving contaminant removal performance. Our products target not only compliance with emerging PFAS regulations, but also broader opportunities in water quality improvement positioning us to serve a large and expanding market.

As part of this strategic pivot, we have invested in the commissioning of two state-of-the-art laboratory facilities-one in Pennsylvania and one in North Dakota-referred to as our "Design Centers." The Design Centers are dedicated sites for water treatment innovation and development. Together, we believe these facilities represent the only known facilities that have integrated capability in North America to thermally reactivate spent GAC under controlled conditions and subsequently conduct RSSCTs to directly compare reactivated GAC performance against virgin carbon counterpart. This combination allows us to evaluate reactivated GAC as a sustainable and cost-effective alternative to virgin carbon and address key water utility questions including how to optimize media changeout schedules, strategies to reduce operational costs, and provide lab-based validation of treatment performance for PFAS and other contaminants.

These Design Centers will also function as a direct resource for the water treatment industry, offering thermal reactivation, contaminant analysis, and carbon performance evaluations. By enabling municipal and industrial utilities to lower compliance costs and improve operational efficiency, we expect to build strong technical credibility and customer engagement ahead of large-scale market adoption. Importantly, we believe our technology platform is not solely dependent on PFAS regulations as market demand for improved water treatment solutions is broad.

29

Our investment in our Design Centers also serves as the basis for our planned commercial thermal reactivation plants which we intend to open and operate in the future. Data generated from the Design Centers is being used to define permitting requirements, capital expenditure parameters, and projected operating costs accelerating the commercialization timeline while avoiding costly future reliance on third-party providers.

On May 14, 2025, the EPA under the new Trump Administration announced the agency will keep the regulations for PFOA and PFOS. As part of this action, the EPA also announced its intent to extend the PFOA and PFOS MCL compliance deadlines and establish a federal exemption framework. Additionally, the EPA announced its intent to rescind the regulations and reconsider the regulatory determinations for PFHxS, PFNA, HFPO-DA (commonly known as GenX), and the Hazard Index mixture of these three PFAS plus PFBS to ensure the determinations and any resulting drinking water regulation follow the Safe Drinking Water Act process.

In light of evolving water regulations and funding dynamics, we believe the Company is well positioned to capture a meaningful share in the rapidly growing water treatment sector.

Additional Information

In May 2024, we announced the appointment of David Mazyck to head our new business line to address the potable (drinking) water market with new sorbent technologies under development. In June 2025, he was appointed our Executive Director of Innovation and Commercialization. In addition, in May 2024, we announced the appointment of Dennis Baranik as Director of National Sales. Mr. Baranik oversees product sales and IP licensing in the Company's core business for mercury emissions capture as well as support both product and business development for the water market. Also, in June 2025, we announced the appointment of Christopher Rinaldi as Director of Strategic Operations, with a focus on our water treatment business.

Effective on October 17, 2024, as part of our rebranding, we changed our corporate name from Midwest Energy Emissions Corp. to Birchtech Corp. pursuant to a certificate of amendment to our certificate of incorporation filed with the State of Delaware, and on October 17, 2024 our common stock commenced trading under the ticker symbol "BCHT".

On October 9, 2024, we received conditional approval to list our shares of common stock on the TSX and graduate from the TSXV to the TSX. On November 12, 2024, our shares commenced trading on the TSX under the ticker symbol "BCHT".

Other Recent Developments

On February 27, 2024, and pursuant to a Debt Restructuring Agreement entered into on such date with AC Midwest Energy LLC ("AC Midwest"), we made an approximate $9.0 million principal payment against an approximate $13.2 million unsecured note held by AC Midwest and repaid in full the remaining principal balance of approximately $272,000 due on a secured note held by AC Midwest. As part of the restructuring, we negotiated a reduction in the profit participation preference held by AC Midwest from approximately $17.7 million to $7.9 million (the "Restructured Profit Share"). Such Restructured Profit Share is "non-recourse" and shall only be paid from net litigation proceeds from claims relating to our intellectual property. In addition, pursuant to the Debt Restructuring Agreement, in March 2024, we were able to facilitate the private sale of certain shares of common stock held by AC Midwest and received a $960,000 credit toward the remaining balance due on the unsecured note. In August 2024, we repaid in full the remaining principal balance of approximately $3.2 million due on the unsecured note held by AC Midwest. As a result, the only remaining debt obligation to AC Midwest is the "non-recourse" Restructured Profit Share.

Following a five-day trial, on March 1, 2024, we were awarded a $57.1 million patent infringement verdict by a federal jury in the U.S. District Court for the District of Delaware against a remaining group of defendants in the lawsuit commenced by us in 2019. Such group of affiliated defendants included multiple limited liability companies with refined coal industry operations, including CERT Operations II LLC, CERT Operations IV LLC, CERT Operations V LLC, and CERT Operations RCB LLC. The jury determined that these defendants infringed our patented technologies for mercury emissions and were liable for willful infringement, along with inducing and contributory infringement. Following the trial, the Court entered non-final judgments on the verdict against the CERT defendants and the parties submitted post-trial motions relating to the jury trial. The CERT defendants also asserted that the Company's claims were barred due to their defense that they had an implied license to the asserted patents. A bench trial was held on such issue. On June 10, 2025, the Court ruled that the CERT defendants failed to prove that they had such an implied license and denied their motion to alter or amend the non-final judgment. In addition, on September 25, 2025, the Court issued a Memorandum Opinion and Order that denied the CERT defendants' post-trial motion that they should not be held liable as a matter of law for induced infringement, contributory infringement or willful infringement. We are awaiting the Court's determination as to the final judgment.

30

In July 2024, we commenced three additional patent infringement lawsuits in U.S. District Courts in Arizona, Iowa and Missouri against multiple utilities and related entities. These actions allege willful infringement of our patents related to mercury emissions control. In October 2024, we entered into an agreement with one of the utility defendants and an affiliated entity in the Arizona action, and in January 2025, we entered into an agreement with another utility named in the Arizona action. Such agreements provide such parties and their affiliates with a non-exclusive license to certain Company patents related to our two-part SEA® process for use in connection with a certain designated coal-fired power plant operated by them. The agreements include one-time license fees which have been received by us. One agreement provides us with a right of first refusal for certain of such utility's product supply for mercury emissions capture at such designated power plant and the other agreement provides us with the right to be included in such party's bidding process for certain product supply for mercury emissions capture at such party's designated power plant.

On December 17, 2024, the U.S. Judicial Panel on Multidistrict Litigation ordered the consolidation of the three lawsuits in the U.S. District Court for the Southern District of Iowa for coordinated pretrial proceedings. In January 2025, we initiated an additional infringement suit in the Western District of Missouri against several Evergy-affiliated entities. One of such defendants was dismissed from the Western District of Missouri action and named as a defendant in a separate case commenced in the U.S. District Court for the District of Kansas. Such cases were transferred to the Iowa court pursuant to the existing transfer order.

Between January and July 2025, certain defendants in the consolidated Iowa actions filed IPR petitions with the U.S. Patent and Trademark Office seeking to invalidate various asserted claims.

On March 19, 2025, we announced that our Board of Directors authorized a share repurchase program under which the Company may purchase up to $5.0 million of its common stock. Purchases under the share repurchase program may be made from time to time, in such amounts as management deems appropriate, through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades, accelerated share repurchase transactions, purchases through 10b5-1 trading plans, or by any combination of such methods. The timing and amount of any repurchases pursuant to the share repurchase program will be determined based upon a variety of factors, including general market conditions, share price, corporate and regulatory requirements and limitations, corporate liquidity requirements and priorities, and other factors. The share repurchase program does not have an expiration date, does not require the Company to repurchase any specific number of shares of its common stock, if any, and may be modified, suspended or terminated at any time without notice. During the three and nine months ended September 30, 2025, there were no repurchases made under the program.

Effective as of August 5, 2025, we entered into separate agreements with two utilities, which are affiliated with each other, and named as defendants in the Southern District of Iowa action. In addition, as of September 9, 2025, we entered into an agreement with a utility and its affiliated entities, named as defendants in the Western District of Missouri and District of Kansas actions. Such agreements provide such parties and their affiliates with a non-exclusive license to certain Company patents related to our two-part Sorbent Enhancement Additive (SEA®) process for use in connection with certain designated coal-fired power plants operated by them. Each agreement includes a one-time license fee. The agreements effective as of August 5, 2025 entered into with the two utilities, provide us with the right to be included in each utility's bidding process for certain product supply for mercury emissions capture at such party's operated power plants. Such utilities have also agreed to withdraw from the IPR petitions.

Effective as of September 30, 2025, we entered into an agreement with another utility not named as a defendant in our patent litigations, but a party to the IPR petitions filed with the U.S. Patent and Trademark Office. Such agreement provides such utility and its affiliates with a with a non-exclusive license to certain Company patents related to the Company's two-part SEA® process for use in connection with a certain designated coal-fired power plant operated by them. Such agreement includes a one-time license fee and provides the Company with the right to be included in such party's bidding process for certain product supply for mercury emissions capture at such party's designated power plant. Such party has agreed to withdraw from IPR petitions.

31

Effective as of October 15, 2025, we entered into an agreement with another utility named as a defendant in the Southern District of Iowa action. While the terms of the agreement are confidential, it includes a resolution of the disputes between the Company and that utility and its affiliates and provides for their withdrawal from related proceedings. As a result of this and the other agreements described above, the Company and several defendants have resolved their respective claims, and those defendants have been dismissed from the applicable actions. There remain two utilities in the consolidated Iowa actions.

As described above, between January and July 2025, certain defendants in the consolidated Iowa actions filed IPR petitions seeking to invalidate various asserted claims. In September and October 2025, the U.S. Patent Trial and Appeal Board ("PTAB") granted the institution of the review of certain of the Company's asserted patents. On October 13, 2025, the Court in the consolidated Iowa actions ruled to stay the litigation pending completion of the IPR process in the PTAB. No assurance can be given as to the ultimate outcome of these proceedings.

Results of Operations

Revenues

We generated revenues of approximately $7,362,000 and $5,237,000 for the three months ended September 30, 2025 and 2024, respectively, and approximately $13,837,000 and $11,840,000 for the nine months ended September 30, 2025 and 2024, respectively. Such revenues were primarily derived from sorbent product sales which were approximately $4,716,000 and $5,092,000 for the three months ended September 30, 2025 and 2024, respectively and approximately $10,637,000 and $11,479,000 for the nine months ended September 30, 2025 and 2024, respectively. Revenues from product sales can be dependent on natural gas prices, extreme weather, and the maintenance and downtime requirements of customer plants. The decrease in product sales from the prior year was primarily due to the mix of plants running, unexpected customer forced outages and products sold in the first nine months of 2025 resulting in decreased product revenues for the nine months ended September 30, 2025 compared to the prior year period. This decrease was offset by an increase in licensing revenues for the nine months ended September 30, 2025 compared to September 30, 2024, resulting in an overall increase in the revenues for the nine months ended September 30, 2025 compared to the prior year period.

Licensing revenues were approximately $2,600,000 and $133,000 for the three months ended September 30, 2025 and 2024, respectively and approximately $3,125,000 and $274,000 for the nine months ended September 30, 2025 and 2024, respectively. Such increase was primarily due to new licensing agreements which were entered into during the nine months ended September 30, 2025 with primarily utility defendants.

Other revenues, consisting of demonstration, consulting and equipment sales, for the three months ended September 30, 2025 and 2024 were approximately $46,000 and $12,000, respectively and approximately $75,000 and $87,000 for the nine months ended September 30, 2025 and 2024, respectively. Other revenues have not been material in relation to total revenues.

Cost of Sales

Cost of sales were approximately $3,330,000 and $3,642,000 for the three months ended September 30, 2025 and 2024, respectively, and approximately $7,602,000 and $8,056,000 for the nine months ended September 30, 2025 and 2024, respectively. This decrease in cost of sales of approximately $454,000 for the nine months ended September 30, 2025 was primarily attributable to decreased product sales in the first nine months of 2025 compared to the prior year period, together with a change in the mix of products sold in the first nine months of 2025 compared to the first nine months of 2024.

Gross Profit

Gross profit was approximately $4,032,000 and $1,595,000 for the three months ended September 30, 2025 and 2024, respectively, and approximately $6,235,000 and $3,784,000 for the nine months ended September 30, 2025 and 2024. The increase in gross profit for the three and nine months ended September 30, 2025 was primarily due to significantly higher licensing revenues in 2025 compared to 2024, which typically carry higher margins than product sales, thus contributing to the overall improvement in gross profit.

32

Operating Expenses

Operating expenses consisted of selling, general and administrative expenses ("SG&A") and research and development expenses ("R&D") in 2025 and SG&A and in 2024. Operating expenses decreased significantly in the nine months ended September 30, 2025 compared to the prior year period, despite incurring costs related to the development of the Company's water treatment business. SG&A expenses were approximately $2,748,000 and $2,702,000 for the three months ended September 30, 2025 and 2024, respectively, and approximately $6,617,000 and $10,863,000 for the nine months ended September 30, 2025 and 2024, respectively. Total SG&A expenses decreased in the first nine months of 2025 compared to the prior year period, as a result of variances in individual categories. This included decreases in salaries and wages, professional fees and consulting fees. The decrease in salaries and wages was primarily due to the payment of bonus compensation in the first nine months of 2024 for which there were no comparable expenses in the first nine months of 2025, along with greater stock-based compensation in the first nine months of 2024 compared to the comparable period in 2025. The decrease in professional fees was primarily due to lower legal fees in the first nine months of 2025 in connection with the Company's patent litigation compared to the prior year period which had greater legal fees due to trial preparation and the jury trial in the U.S. District Court for the District of Delaware.

Total R&D expenses were approximately $473,000 and $0 for the three months ended September 30, 2025 and 2024, respectively, and $1,335,000 and $0 for the nine months ended September 30, 2025 and 2024, respectively. R&D expenses relate to research conducted to develop water treatment products utilizing new sorbent technologies, and increased in the first nine months of 2025 compared to the prior year period as the Company had not incurred any research related costs during the first nine months of 2024. The Company began incurring research and development costs when the lab equipment at the Company's labs was placed into service.

Operating Income (Loss)

Our operating income was approximately $811,000 for the three months ended September 30, 2025 compared to a loss of $1,107,000 for the three months ended September 30, 2024. For the nine months ended September 30, 2025 and 2024, we had an operating loss of approximately $1,717,000 and $7,079,000, respectively. Such decrease in operating loss was primarily due to our increased license fee revenue in 2025 compared to 2024 coupled with a decrease in total operating expenses during the first nine months of 2025 as discussed above.

Other Income (Expense)

Interest expense related to the financing of capital was approximately $Nil and $7,000 for the three months ended September 30, 2025 and 2024, respectively, and $54 and $259,000 for the nine months ended September 30, 2025 and 2024, respectively. The approximate breakdown of interest expense for the three and nine months ended September 30, 2025 and 2024 is as follows:

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
		2025				2024				2025				2024
		(In thousands)								(In thousands)
Interest expense on notes payable		$	-			$	-			$	-			$	4
Amortization of discount of notes payable			-				-				-				242
Other interest			-				7				-				13
		$	-			$	7			$	-			$	259

Gain (Loss) on change in fair value of profit share liability and unsecured note was approximately $(38,000) and $282,000 for the three months ended September 30, 2025 and 2024, respectively, and $(767,000) and $(2,672,000) for the nine months ended September 30, 2025 and 2024, respectively. The change is primarily attributed to the modification of the terms of the profit share liability (see Note 7 to the unaudited condensed consolidated financial statements).

33

Net Income (Loss)

For the three months ended September 30, 2025, we had a net income of approximately $788,000 compared to a net loss of approximately $458,000 for the three months ended September 30, 2024. For the nine months ended September 30, 2025, we had a net loss of approximately $2,433,000, an improvement from a net loss of approximately $9,459,000 for the nine months ended September 30, 2024. This improvement was primarily due an increase in license fee revenues in 2025 compared to 2024, and a decrease in SG&A.

Liquidity and Capital Resource

We had approximately $1,768,000 in cash on our balance sheet at September 30, 2025 compared to approximately $3,456,000 at December 31, 2024. Total current assets were approximately $6,027,000 and total current liabilities were approximately $11,054,000 at September 30, 2025, resulting in a working capital deficiency of approximately $5,027,000. This compares to total current assets of approximately $6,099,000 and total current liabilities of approximately $8,806,000 at December 31, 2024, resulting in a working capital deficiency of approximately $2,707,000. Our accumulated deficit was approximately $75,186,000 at September 30, 2025 compared to $72,753,000 at December 31, 2024. Additionally, we had a net loss in the amount of approximately $2,433,000 and cash used in operating activities of approximately $1,664,000 for the nine months ended September 30, 2025.

Based on the Company's current cash levels and burn rate, discussed above, the Company believes its cash and financial resources may be insufficient to meet the Company's anticipated needs for the twelve months following the date of issuance of the financial statements for the quarterly period ended September 30, 2025, included elsewhere in this Form 10-Q, which raises substantial doubt about the Company's ability to continue as a going concern within one year from the issuance date of the financial statements.

In addition to maintaining the revenue stream from our legacy mercury emissions control business, our plans and expectations over the next twelve months to mitigate such financial condition include receiving additional cash inflows from the judgment expected in connection with the $57.1 million jury verdict awarded to us in March 2024, additional licensing revenues and product sales from the other patent litigation recently commenced, and revenues from our entry into the water treatment business. During 2024, we opened two new state of the art laboratories and have added personnel to support our entry into the water business which we believe will lead to a vibrant new revenue stream. In addition, management is exploring additional financing opportunities. While management believes these plans will alleviate substantial doubt, there is no assurance that they will be successfully realized or implemented.

Total Assets

Total assets were approximately $10,138,000 at September 30, 2025 versus approximately $10,261,000 at December 31, 2024. The change in total assets is primarily attributable to an approximate $1,688,000 decrease in cash, a $153,000 decrease in intellectual property, offset by an approximate $1,808,000 increase in accounts receivable.

Total Liabilities

Total liabilities were approximately $11,280,000 at September 30, 2025 versus approximately $9,069,000 at December 31, 2024. The increase is primarily attributable to an increase in accounts payable and accrued liabilities and an increase in the fair value of the non-recourse profit share liability.

Operating Activities

Net cash used in operating activities consists of net loss, adjusted by certain non-cash items, and changes in operating assets and liabilities.

Net cash used by operating activities was approximately $1,664,000 for the nine months ended September 30, 2025 compared to net cash used by operating activities of approximately $3,275,000 for the nine months ended September 30, 2024. The decrease in net cash provided by operating activities was primarily due to the following: (i) a net loss of $2.4 million for the nine months ended September 30, 2025 compared to net loss of $9.5 million for the nine months ended September 30, 2024; and (ii) certain other changes in operating assets and liabilities including accounts receivable, inventory, prepaid expenses and other assets, accrued salaries, and accounts payable and accrued liabilities.

34

Investing Activities

The Company had net cash used in investing activities of approximately $23,000 for the nine months ended September 30, 2025 for the purchase of lab equipment compared to net cash used in investing activities of approximately $702,000 for the nine months ended September 30, 2024 for the purchase of a truck and lab equipment.

Financing Activities

Net cash used in financing activities was approximately $Nil for the nine months ended September 30, 2025 compared to approximately $12,569,000 used in financing activities for the nine months ended September 30, 2024. During the nine months ended September 30, 2024, we repaid the remaining principal of approximately $272,000 on the AC Midwest secured note and approximately $12,195,000 of the principal remaining on the AC Midwest unsecured note.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimated are discussed in our Annual Report on Form 10-K for the year ended December 31, 2024, and there have been no material changes to such policies or estimates during the nine months ended September 30, 2025.

Non-GAAP Financial Measures

Adjusted EBITDA

To supplement our consolidated financial statements presented in accordance with GAAP and to provide investors with additional information regarding our financial results, we consider and are including herein Adjusted EBITDA, a Non-GAAP financial measure. We view Adjusted EBITDA as an operating performance measure and, as such, we believe that the GAAP financial measure most directly comparable to it is net income (loss). We define Adjusted EBITDA as net income adjusted for interest and financing fees, income taxes, depreciation, amortization, stock-based compensation, and other non-cash income and expenses. We believe that Adjusted EBITDA provides us an important measure of operating performance because it allows management, investors, debtholders and others to evaluate and compare ongoing operating results from period to period by removing the impact of our asset base, any asset disposals or impairments, stock based compensation and other non-cash income and expense items associated with our reliance on issuing equity-linked debt securities to fund our working capital.

Our use of Adjusted EBITDA has limitations as an analytical tool, and this measure should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP, as the excluded items may have significant effects on our operating results and financial condition. Additionally, our measure of Adjusted EBITDA may differ from other companies' measure of Adjusted EBITDA. When evaluating our performance, Adjusted EBITDA should be considered with other financial performance measures, including various cash flow metrics, net income and other GAAP results. In the future, we may disclose different non-GAAP financial measures in order to help our investors and others more meaningfully evaluate and compare our future results of operations to our previously reported results of operations.
