   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech, Inc. and subsidiaries ("Fuel Tech", the "Company", "we", "us" or "our") develops and provides&#160;proprietary technologies for air pollution control, process optimization, water treatment, and advanced engineering services. These technologies enable customers to operate in a cost-effective and environmentally sustainable manner.</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The Company&#8217;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#160;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#160;The Company also&#160;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#8217;s FUEL CHEM&#174; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity.&#160; Water treatment technologies include DGI&#174;&#160;Dissolved Gas Infusion Systems which utilize a patented gas-infusing saturator vessel and a patent-pending channel injector to deliver supersaturated oxygen-water solutions and potentially other gas-liquid combinations to target process applications or environmental issues within the municipal and industrial water sectors. The infusion process has a variety of potential applications in the water and wastewater treatment sector, including aquaculture, agriculture/horticulture, pulp &amp; paper, tanneries, landfill leachate, irrigation, treatment of natural waters, wastewater odor management as well as supplying oxygen or other gases for biochemical reactions and pH adjustment.</p>

For trade receivables and other financial instruments, we are&#160;required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted these ASUs on <em style="font: inherit;"> January 1, 2023 </em>using the prospective method. Application of the amendments did <em style="font: inherit;">not</em> require a cumulative-effect adjustment to retained earnings as of the effective date and did <em style="font: inherit;">not</em> have a material impact on our financial statements.&#160;</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">For the general risk categories, the Company uses historical losses over a fixed period, excluding certain write-off activity that was&#160;<em style="font: inherit;">not</em> considered a credit loss event, to determine the historical credit loss. Historical loss rates are then adjusted to consider current economic conditions&#160;and past, current, and future events and circumstances when determining expected credit losses. Investments in financial assets issued by US Government and Government Agency are considered as having <em style="font: inherit;">zero</em> expected credit losses and are excluded from the allowance for credit loss calculation.</p>

The Company experienced recovery&#160;in&#160;the FUEL CHEM segment&#160;as dormant accounts returned to service as a result of outage completions and&#160;increased dispatch..&#160;We continue to invest in development of new technologies to expand our product offerings into the water and waste-water treatment market. Our capital resources are sufficient for our immediate and longer-term needs, and we continue to enjoy the services and support of a dedicated workforce.&#160;We expect that our cost control efforts will maintain our existing levels of operating expenditures&#160;<span style="background-color:#ffffff;">and that new business opportunities will lead to an improved market outlook.</span></p>

We continue to experience a challenging operational environment resulting from customers delaying the timing of purchasing decisions.&#160; Our Consolidated APC backlog at </span>June 30, 2024<span style="background-color:#ffffff;"> was $</span>4,250<span style="background-color:#ffffff;">&#160;and</span> our global sales pipeline is in the $50 -75 million range.</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;"><span style="background-color:#ffffff;">In&#160;2022, the Board of Directors approved an investment plan that would hold $20,000 in funds at BMO Harris Bank (BMO Harris) to be invested in held-to-maturity debt securities of United States (US) Treasuries, including Notes, Bonds, and Bills, or US Government Agency securities. The funds are held in money market funds until they are invested in those securities. The investments are structured to create a maturity &#8220;ladder&#8221; where the proceeds from maturities are re-invested to maintain a balance of short- and long-term investments based on&#160;expected business needs. Maturities are between three and thirty-six months. This strategy allows the Company to provide returns on excess cash, while managing liquidity and minimizing exposure to interest rate fluctuations.</span></p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;"><span style="background-color:#ffffff;">On June 30, 2022, the Company entered into the Investment Collateral Security agreement&#160;to use for the sole purpose of issuing standby letters of credit, which replaces the Cash Collateral Security agreement with BMO Harris Bank, N.A. (the Former Collateral agreement). The Investment Collateral Security agreement requires us to pledge our investments as collateral for 150% of the aggregate face amount of outstanding standby letters of credit. The Company pays 250 basis points on the face values of outstanding letters of credit. There are no financial covenants set forth in the Investment Collateral Security agreement. At </span>June 30, 2024<span style="background-color:#ffffff;">, the Company had outstanding standby letters of credit totaling approximately $</span>480<span style="background-color:#ffffff;">&#160;under the Investment Collateral Security agreement. At </span>June 30, 2024<span style="background-color:#ffffff;">, the investments held as collateral totaled $</span>720<span style="background-color:#ffffff;">. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments.</span></p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The Company&#8217;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#160;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#160;The Company also&#160;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#8217;s FUEL CHEM&#174; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity.&#160; Water treatment technologies include DGI&#174;&#160;Dissolved Gas Infusion Systems which utilize a patented gas-infusing saturator vessel and a patent-pending channel injector to deliver supersaturated oxygen-water solutions and potentially other gas-liquid combinations to target process applications or environmental issues within the municipal and industrial water sectors. The infusion process has a variety of potential applications in the water and wastewater treatment sector, including aquaculture, agriculture/horticulture, pulp &amp; paper, tanneries, landfill leachate, irrigation, treatment of natural waters, wastewater odor management as well as supplying oxygen or other gases for biochemical reactions and pH adjustment.</p>

HTM debt investments with original maturities of approximately <em style="font: inherit;">three</em> months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately <em style="font: inherit;">three</em> months and remaining maturities of less than <em style="font: inherit;">one</em> year are classified as short-term investments. HTM debt investments with remaining maturities beyond <em style="font: inherit;">one</em> year are classified as long-term investments. Interest income, including amortization of premium and accretion of discount, is&#160;included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method. Accrued interest is included in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Due to the creditworthiness of the entities issuing these securities, there is <em style="font: inherit;">no</em> impairment recorded related to the unrealized losses.</span></p>

For trade receivables and other financial instruments, we are&#160;required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted these ASUs on <em style="font: inherit;"> January 1, 2023 </em>using the prospective method.

Historical loss rates are then adjusted to consider current economic conditions&#160;and past, current, and future events and circumstances when determining expected credit losses.

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Condensed Consolidated Balance Sheets. In our Air Pollution Control (APC) technology segment, amounts are billed as work progresses&#160;in accordance with agreed-upon contractual terms. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered contract assets.&#160;These assets are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.&#160;At <em style="font: inherit;"> June 30, 2024</em>,&#160;<em style="font: inherit;"> December 31, 2023</em>, and <em style="font: inherit;"> December 31, 2022, </em>contract assets for APC technology projects were approximately $1,543,&#160;$2,285, and $3,082, respectively.

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The Company will periodically bill in advance of costs incurred before revenue is recognized, resulting in contract liabilities. These liabilities are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.

Participants in the Incentive Plan <em style="font: inherit;"> may </em>be our directors, officers, employees, consultants, or advisors (except consultants or advisors in capital-raising transactions) as the directors determine are key to the success of our business. There are a maximum of 5,742,376&#160;shares that <em style="font: inherit;"> may </em>be issued or reserved for awards to participants under the Incentive Plan.

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Stock options granted to employees under the Incentive Plans have a 10-year life and they vest as follows: 50% after the <em style="font: inherit;">second</em> anniversary of the award date, 25% after the <em style="font: inherit;">third</em> anniversary, and the final 25% after the <em style="font: inherit;">fourth</em> anniversary of the award date. Fuel Tech calculates stock compensation expense for employee option awards based on the grant date fair value of the award, less expected annual forfeitures, and recognizes expense on a straight-line basis over the <em style="font: inherit;">four</em>-year service period of the award. Stock options granted to members of our board of directors vest immediately. Stock compensation for these awards is based on the grant date fair value of the award and is recognized in expense immediately.</p>
   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech uses the Black-Scholes option pricing model to estimate the grant date fair value of employee stock options. The principal variable assumptions utilized in valuing options and the methodology for estimating such model inputs include: (<em style="font: inherit;">1</em>)&#160;risk-free interest rate &#8211; an estimate based on the yield of zero&#8211;coupon treasury securities with a maturity equal to the expected life of the option; (<em style="font: inherit;">2</em>)&#160;expected volatility &#8211; an estimate based on the historical volatility of Fuel Tech&#8217;s Common Stock for a period equal to the expected life of the option; and (<em style="font: inherit;">3</em>)&#160;expected life of the option &#8211; an estimate based on historical experience including the effect of employee terminations.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech is subject to various claims and contingencies related to, among other things, workers compensation, general liability (including product liability), and lawsuits. The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when <em style="font: inherit;">no</em> amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is <em style="font: inherit;">not</em> probable or the amount is <em style="font: inherit;">not</em> estimable, or both, if there is a reasonable possibility that a material loss <em style="font: inherit;"> may </em>have been incurred.</p>

   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;">From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business. In the opinion of management, based upon presently available information, either adequate provision for anticipated costs have been accrued or the ultimate anticipated costs will <em style="font: inherit;">not</em> materially affect our consolidated financial position, results of operations, or cash flows.&#160;We do <em style="font: inherit;">not</em> believe we have any pending loss contingencies that are probable or reasonably possible of having a material impact on our consolidated financial position, results of operations or cash flows.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.</p>

The Company has the positive intent and ability to hold these investments to maturity and does&#160;<em style="font: inherit;">not</em> expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from <span style="-sec-ix-hidden:c115175439">three</span> to <span style="-sec-ix-hidden:c115175440">thirty-six</span> months. HTM debt investments with original maturities of approximately <em style="font: inherit;">three</em> months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately <em style="font: inherit;">three</em> months and remaining maturities of less than <em style="font: inherit;">one</em> year are classified as short-term investments. HTM debt investments with remaining maturities beyond <em style="font: inherit;">one</em> year are classified as long-term investments. Interest income, including amortization of premium and accretion of discount, is&#160;included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method. Accrued interest is included in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Due to the creditworthiness of the entities issuing these securities, there is <em style="font: inherit;">no</em> impairment recorded related to the unrealized losses.</span></p>

For trade receivables and other financial instruments, we are&#160;required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted these ASUs on <em style="font: inherit;"> January 1, 2023 </em>using the prospective method. Application of the amendments did <em style="font: inherit;">not</em> require a cumulative-effect adjustment to retained earnings as of the effective date and did <em style="font: inherit;">not</em> have a material impact on our financial statements.&#160;</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">For the general risk categories, the Company uses historical losses over a fixed period, excluding certain write-off activity that was&#160;<em style="font: inherit;">not</em> considered a credit loss event, to determine the historical credit loss. Historical loss rates are then adjusted to consider current economic conditions&#160;and past, current, and future events and circumstances when determining expected credit losses. Investments in financial assets issued by US Government and Government Agency are considered as having <em style="font: inherit;">zero</em> expected credit losses and are excluded from the allowance for credit loss calculation.</p>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The Company&#x2019;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#160;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#160;The Company also&#160;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#x2019;s FUEL CHEM&#xae; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity.&#160; Water treatment technologies include DGI&#xae;&#160;Dissolved Gas Infusion Systems which utilize a patented gas-infusing saturator vessel and a patent-pending channel injector to deliver supersaturated oxygen-water solutions and potentially other gas-liquid combinations to target process applications or environmental issues within the municipal and industrial water sectors. The infusion process has a variety of potential applications in the water and wastewater treatment sector, including aquaculture, agriculture/horticulture, pulp &amp;amp; paper, tanneries, landfill leachate, irrigation, treatment of natural waters, wastewater odor management as well as supplying oxygen or other gases for biochemical reactions and pH adjustment.&lt;/p&gt;

The CARES Act provides tax relief, along with other stimulus measures, including a provision for an Employee Retention Credit (&#x201c;ERC&#x201d;), which allows for employers to claim a refundable tax credit against the employer share of Social Security tax for qualifying periods in &lt;em style="font: inherit;"&gt;2020&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2021.&lt;/em&gt;&#160;Under the provisions of the CARES Act, the Company is eligible for a refundable employee retention credit subject to certain criteria.&lt;/p&gt;

In accordance with IAS &lt;em style="font: inherit;"&gt;20,&lt;/em&gt; management determined it has reasonable assurance for receipt of the ERC and recorded the ERC benefit of $1,677 as other income on the Statement of Operations for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2024 &lt;/em&gt;and as a component of Accounts Receivable on the Balance Sheet as of &lt;em style="font: inherit;"&gt; June 30, 2024.&lt;/em&gt;&lt;/p&gt;

Carrying value of cash equivalents approximates fair value due to the maturities of &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less.&lt;/span&gt;&lt;/p&gt;

The Company has the positive intent and ability to hold these investments to maturity and does&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from &lt;span style="-sec-ix-hidden:c115175439"&gt;three&lt;/span&gt; to &lt;span style="-sec-ix-hidden:c115175440"&gt;thirty-six&lt;/span&gt; months. HTM debt investments with original maturities of approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months and remaining maturities of less than &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as short-term investments. HTM debt investments with remaining maturities beyond &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as long-term investments. Interest income, including amortization of premium and accretion of discount, is&#160;included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method. Accrued interest is included in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Due to the creditworthiness of the entities issuing these securities, there is &lt;em style="font: inherit;"&gt;no&lt;/em&gt; impairment recorded related to the unrealized losses.&lt;/span&gt;&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;Inventories consist primarily of equipment constructed for resale&#160;and spare parts and are stated at the lower of cost or net realizable value, using the weighted-average cost method. &lt;span style="background-color:#ffffff;"&gt;At&#160;&lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;&#160;and &lt;/span&gt;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;, inventory included equipment constructed for resale of $&lt;/span&gt;197&lt;span style="background-color:#ffffff;"&gt;&#160;and $&lt;/span&gt;207&lt;span style="background-color:#ffffff;"&gt;, respectively, and spare parts, net of reserves, of $&lt;/span&gt;265&lt;span style="background-color:#ffffff;"&gt;&#160;and $&lt;/span&gt;232&lt;span style="background-color:#ffffff;"&gt;, respectively. Usage is recorded in cost of sales in the period that parts were issued to a project,&#160;used to service equipment, or sold to customers. Equipment constructed for resale that is in process is recorded in Other assets. In process equipment for inventory recorded as Other assets was $613&#160;and $618&#160;as of&#160;&lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;&lt;span style="background-color:#ffffff"&gt;&#160;and &lt;/span&gt;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;, respectively. In&lt;/span&gt;ventories are periodically evaluated to identify obsolete or otherwise impaired parts and are written off when management determines usage is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable. The Company estimates the balance of excess and obsolete inventory by analyzing inventory by age using last used and original purchase date and existing sales pipeline for which the inventory could be used.&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;&lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;In &lt;em style="font: inherit;"&gt; June 2016, &lt;/em&gt;the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;13,&lt;/em&gt;&#160;Financial Instruments - Credit Losses (Topic &lt;em style="font: inherit;"&gt;326&lt;/em&gt;): Measurement of Credit Losses on Financial Instruments, and in &lt;em style="font: inherit;"&gt; November 2019, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;2019&lt;/em&gt;-&lt;em style="font: inherit;"&gt;10,&lt;/em&gt; Financial Instruments - Credit Losses (Topic &lt;em style="font: inherit;"&gt;326&lt;/em&gt;), Derivatives and Hedging (Topic &lt;em style="font: inherit;"&gt;815&lt;/em&gt;), and Leases (Topic &lt;em style="font: inherit;"&gt;842&lt;/em&gt;).&#160;This guidance&#160;requires the measurement of all expected losses based on historical experience, current conditions and reasonable and supportable forecasts. For trade receivables and other financial instruments, we are&#160;required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted these ASUs on &lt;em style="font: inherit;"&gt; January 1, 2023 &lt;/em&gt;using the prospective method. Application of the amendments did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; require a cumulative-effect adjustment to retained earnings as of the effective date and did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; have a material impact on our financial statements.&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;For the general risk categories, the Company uses historical losses over a fixed period, excluding certain write-off activity that was&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; considered a credit loss event, to determine the historical credit loss. Historical loss rates are then adjusted to consider current economic conditions&#160;and past, current, and future events and circumstances when determining expected credit losses. Investments in financial assets issued by US Government and Government Agency are considered as having &lt;em style="font: inherit;"&gt;zero&lt;/em&gt; expected credit losses and are excluded from the allowance for credit loss calculation.&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;

Carrying value of cash equivalents approximates fair value due to the maturities of &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less.&lt;/span&gt;&lt;/p&gt;

The Company has the positive intent and ability to hold these investments to maturity and does&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from &lt;span style="-sec-ix-hidden:c115175439"&gt;three&lt;/span&gt; to &lt;span style="-sec-ix-hidden:c115175440"&gt;thirty-six&lt;/span&gt; months. HTM debt investments with original maturities of approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months and remaining maturities of less than &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as short-term investments. HTM debt investments with remaining maturities beyond &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as long-term investments. Interest income, including amortization of premium and accretion of discount, is&#160;included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method. Accrued interest is included in Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Due to the creditworthiness of the entities issuing these securities, there is &lt;em style="font: inherit;"&gt;no&lt;/em&gt; impairment recorded related to the unrealized losses.&lt;/span&gt;&lt;/p&gt;

Usage is recorded in cost of sales in the period that parts were issued to a project,&#160;used to service equipment, or sold to customers. Equipment constructed for resale that is in process is recorded in Other assets. In process equipment for inventory recorded as Other assets was $613&#160;and $618&#160;as of&#160;&lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;&lt;span style="background-color:#ffffff"&gt;&#160;and &lt;/span&gt;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;, respectively. In&lt;/span&gt;ventories are periodically evaluated to identify obsolete or otherwise impaired parts and are written off when management determines usage is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable. The Company estimates the balance of excess and obsolete inventory by analyzing inventory by age using last used and original purchase date and existing sales pipeline for which the inventory could be used.&#160;&lt;/p&gt;

For trade receivables and other financial instruments, we are&#160;required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted these ASUs on &lt;em style="font: inherit;"&gt; January 1, 2023 &lt;/em&gt;using the prospective method. Application of the amendments did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; require a cumulative-effect adjustment to retained earnings as of the effective date and did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; have a material impact on our financial statements.&#160;&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;For the general risk categories, the Company uses historical losses over a fixed period, excluding certain write-off activity that was&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; considered a credit loss event, to determine the historical credit loss. Historical loss rates are then adjusted to consider current economic conditions&#160;and past, current, and future events and circumstances when determining expected credit losses. Investments in financial assets issued by US Government and Government Agency are considered as having &lt;em style="font: inherit;"&gt;zero&lt;/em&gt; expected credit losses and are excluded from the allowance for credit loss calculation.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&lt;i&gt;Contract Balances&lt;/i&gt;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Condensed Consolidated Balance Sheets. In our Air Pollution Control (APC) technology segment, amounts are billed as work progresses&#160;in accordance with agreed-upon contractual terms. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered contract assets.&#160;These assets are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.&#160;At &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;,&#160;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;, and &lt;em style="font: inherit;"&gt; December 31, 2022, &lt;/em&gt;contract assets for APC technology projects were approximately $1,543,&#160;$2,285, and $3,082, respectively. There were &lt;span style="-sec-ix-hidden:c115175501"&gt;&lt;span style="-sec-ix-hidden:c115175523"&gt;&lt;span style="-sec-ix-hidden:c115175524"&gt;no&lt;/span&gt;&lt;/span&gt;&lt;/span&gt; contract assets for the FUEL CHEM technology segment as of&#160;&lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;,&#160;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;, and &lt;em style="font: inherit;"&gt; December 31, 2022.&#160;&#160;&lt;/em&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The Company will periodically bill in advance of costs incurred before revenue is recognized, resulting in contract liabilities. These liabilities are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Contract liabilities were $276,&#160;$1,279, and $372&#160;at &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;,&#160;&lt;em style="font: inherit;"&gt; December 31, 2023&lt;/em&gt;, and &lt;em style="font: inherit;"&gt; December 31, 2022, &lt;/em&gt;respectively, and are included in other accrued liabilities on the&#160;Condensed Consolidated Balance Sheets.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;

Revenue recognized that was included in the contract liability balance at the beginning of the period was $438&#160;and $1,221&#160;for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;, respectively, and $9&#160;and $368 for the&#160;&lt;em style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2023&lt;/em&gt;, respectively, which represented primarily revenue from progress towards completion of our APC technology contracts.&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt;"&gt;&#160;&lt;/p&gt;

Diluted earnings per share includes the dilutive effect of the &lt;em style="font: inherit;"&gt;nil&lt;/em&gt; coupon non-redeemable convertible unsecured loan notes, RSUs, warrants, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive.

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Under our stock-based employee compensation plan, referred to as the Fuel Tech, Inc. &lt;em style="font: inherit;"&gt;2014&lt;/em&gt; Long-Term Incentive Plan (Incentive Plan), awards &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be granted to participants in the form of Non-Qualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, RSUs, Performance Awards, Bonuses or other forms of share-based or non-share-based awards or combinations thereof. Participants in the Incentive Plan &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be our directors, officers, employees, consultants, or advisors (except consultants or advisors in capital-raising transactions) as the directors determine are key to the success of our business. There are a maximum of 5,742,376&#160;shares that &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be issued or reserved for awards to participants under the Incentive Plan. As of &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;, Fuel Tech had 1,239,000&#160;shares available for issuance&#160;under the Incentive&#160;Plan.&lt;/p&gt;

Given the Company has a full valuation allowance on its deferred tax assets, there were &lt;em style="font: inherit;"&gt;no&lt;/em&gt; excess tax benefits to record for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt;&#160;and &lt;em style="font: inherit;"&gt;2023&lt;/em&gt;. In addition, we account for forfeitures of awards based on an estimate of the number of awards expected to be forfeited and adjust&#160;the estimate when it is &lt;em style="font: inherit;"&gt;no&lt;/em&gt; longer probable that the employee will fulfill the service condition.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Stock options granted to employees under the Incentive Plans have a 10-year life and they vest as follows: 50% after the &lt;em style="font: inherit;"&gt;second&lt;/em&gt; anniversary of the award date, 25% after the &lt;em style="font: inherit;"&gt;third&lt;/em&gt; anniversary, and the final 25% after the &lt;em style="font: inherit;"&gt;fourth&lt;/em&gt; anniversary of the award date. Fuel Tech calculates stock compensation expense for employee option awards based on the grant date fair value of the award, less expected annual forfeitures, and recognizes expense on a straight-line basis over the &lt;em style="font: inherit;"&gt;four&lt;/em&gt;-year service period of the award. Stock options granted to members of our board of directors vest immediately. Stock compensation for these awards is based on the grant date fair value of the award and is recognized in expense immediately.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech uses the Black-Scholes option pricing model to estimate the grant date fair value of employee stock options. The principal variable assumptions utilized in valuing options and the methodology for estimating such model inputs include: (&lt;em style="font: inherit;"&gt;1&lt;/em&gt;)&#160;risk-free interest rate &#x2013; an estimate based on the yield of zero&#x2013;coupon treasury securities with a maturity equal to the expected life of the option; (&lt;em style="font: inherit;"&gt;2&lt;/em&gt;)&#160;expected volatility &#x2013; an estimate based on the historical volatility of Fuel Tech&#x2019;s Common Stock for a period equal to the expected life of the option; and (&lt;em style="font: inherit;"&gt;3&lt;/em&gt;)&#160;expected life of the option &#x2013; an estimate based on historical experience including the effect of employee terminations.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech is subject to various claims and contingencies related to, among other things, workers compensation, general liability (including product liability), and lawsuits. The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when &lt;em style="font: inherit;"&gt;no&lt;/em&gt; amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable or the amount is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; estimable, or both, if there is a reasonable possibility that a material loss &lt;em style="font: inherit;"&gt; may &lt;/em&gt;have been incurred.&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;"&gt;From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business. In the opinion of management, based upon presently available information, either adequate provision for anticipated costs have been accrued or the ultimate anticipated costs will &lt;em style="font: inherit;"&gt;not&lt;/em&gt; materially affect our consolidated financial position, results of operations, or cash flows.&#160;We do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; believe we have any pending loss contingencies that are probable or reasonably possible of having a material impact on our consolidated financial position, results of operations or cash flows.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;

The warranty liability balance was $159 at &lt;em style="font: inherit;"&gt; June 30, 2024&lt;/em&gt; and &lt;em style="font: inherit;"&gt; December 31, &lt;/em&gt;&lt;em style="font: inherit;"&gt;2023&lt;/em&gt;.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The Company&#x2019;s effective tax rate is approximately 13.8%&lt;span style="background-color:#ffffff;"&gt;&#160;and&#160;&lt;/span&gt;0.0%&lt;span style="background-color:#ffffff;"&gt; for the &lt;/span&gt;&lt;em style="font: inherit;"&gt;six&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;-month periods ended &lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2024 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2023&lt;/em&gt;, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt;-month periods ended &lt;em style="font: inherit;"&gt; June 30, 2024 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2023&lt;/em&gt; primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with &lt;em style="font: inherit;"&gt;no&lt;/em&gt; related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt;-month periods ended &lt;em style="font: inherit;"&gt; June 30, 2024 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2023&lt;/em&gt;.&lt;/p&gt;
