NOTES TO FINANCIAL STATEMENTS

Note 1. Business Organization and Purpose

SCI Engineered Materials, Inc. (“SCI” or the “Company”), formerly Superconductive Components, Inc., an Ohio corporation, was incorporated in 1987. The Company manufactures ceramic and metal sputtering targets for a variety of industrial applications including: Photonics, Semiconductor, Thin Film Battery, and, to a lesser extent High Temperature Superconductive (HTS) materials. Photonics (which includes solar) currently represents the Company’s largest market for its targets. Thin Film Battery is a developing market where manufacturers of batteries use the Company’s targets to produce very small power supplies with small quantities of stored energy. Semiconductor is a developing market.

Note 2. Summary of Significant Accounting Policies

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation of the results of operations for the periods presented have been included. The financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2007. Interim results are not necessarily indicative of results for the full year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Equipment purchased with grant funding

In 2004, the Company received funds of $517,935 from the Ohio Department of Development’s Third Frontier Action Fund (TFAF) for the purchase of equipment related to the grant’s purpose. The Company has elected to record the funds disbursed as a contra asset; therefore, the assets are not reflected in the Company’s financial statements. As assets were purchased, the liability initially created when the cash was received was reduced with no revenue recognized or fixed asset recorded on the balance sheet. As of June 30, 2008, the Company had disbursed the entire amount received. The grant and contract both provide that as long as the Company performs in compliance with the grant, the Company retains the rights to the equipment. Management states that the Company will be in compliance with the requirements and, therefore, will retain the equipment at the end of the grant in 2008.

Note 2. Summary of Significant Accounting Policies (continued)

Stock Based Compensation

In December 2004, the FASB issued SFAS No. 123 (Revised), “Shared Based Payment” (SFAS No. 123R). SFAS No. 123R replaced SFAS No. 123, and superseded APB Opinion No. 25. Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R and related interpretations using the modified-prospective transition method. Under this method, compensation cost recognized in 2008 and 2007 includes compensation cost for all stock-based awards granted on or subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R. Non cash stock based compensation costs were $29,637 and $28,626 for the six months ended June 30, 2008 and 2007, respectively. The four non-employee board members each received compensation of 1,819 shares of the Company’s common stock and $5,000 in cash each year.

Reclassification

Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation.

NOTES TO FINANCIAL STATEMENTS

Note 6. Earnings Per Share

Basic income (loss) per share is calculated as income (loss) available to common stockholders divided by the weighted average of common shares outstanding. Diluted earnings per share is calculated as diluted income available to common stockholders divided by the diluted weighted average number of common shares. Diluted weighted average number of common shares has been calculated using the treasury stock method for Common Stock equivalents, which includes Common Stock issuable pursuant to stock options and Common Stock warrants. At June 30, 2008 all common stock options and warrants are anti-dilutive due to the net loss. The following is provided to reconcile the earnings per share calculations:

	Three months ended June 30, 2008			Three months ended June 30, 2007		Six months ended June 30, 2008			Six months ended June 30, 2007
(Loss) income applicable to common shares	$	(108,878	)	$	95,379	$	(187,245	)	$	156,695
Weighted average common shares outstanding – basic		3,510,964			3,462,073		3,500,419			3,451,032
Effect of dilutions – stock options/warrants		0			825,009		0			789,318
Weighted average common shares outstanding – basic		3,510,964			4,287,082		3,500,419			4,240,350

Note 7. Capital Requirements

The Company’s accumulated deficit since inception was $7,701,388 (unaudited) at June 30, 2008. Historically, the losses have been financed primarily from additional investments and loans by major shareholders and private offerings of common stock and warrants to purchase common stock. The Company cannot assure that it will be able to raise additional capital in the future to fund its operations.

As of June 30, 2008, cash on-hand was $846,333. Management believes, based on forecasted sales and expenses, that funding will be adequate to sustain operations at least through June 30, 2009.

Numerous factors may make it necessary for the Company to seek additional capital. In order to support the initiatives included in its business plan, the Company may need to raise additional funds through public or private financing, collaborative relationships or other arrangements. Its ability to raise additional financing depends on many factors beyond its control, including the state of capital markets, the market price of its common stock and the development or prospects for development of competitive products by others. Because the common stock is not listed on a major stock exchange, many investors may not be willing or allowed to purchase it or may demand steep discounts. The additional financing may not be available or may be available only on terms that would result in further dilution to the current owners of the common stock.

NOTES TO FINANCIAL STATEMENTS

Note 8. Subsequent Event

During the third quarter of 2006, the Company met with the Development Financing Advisory Council (DFAC) of the Ohio Department of Development (ODOD) and applied for a loan from the Innovation Ohio Loan Fund. The Company was subsequently approved for a 166 Direct Loan from the ODOD in the amount of $400,000. These funds were received in July of 2008. The funds will be used to reduce the balance on current outstanding capital lease obligations. The term of the loan is 84 months at an interest rate of 3%. There is also a one-quarter percent annual servicing fee to be charged monthly on the outstanding principal balance. During each of the first 12 months the Company will make only monthly servicing fee and interest payments. During months 13 through 84, the Company will make monthly servicing fee, interest and principal payments. The loan principal balance will be fully amortized over the last 72 months.

Overview

SCI Engineered Materials, Inc. (“SCI” or the “Company”), formerly Superconductive Components, Inc., an Ohio corporation, was incorporated in 1987. We manufacture ceramic and metal sputtering targets for a variety of industrial applications including: Photonics, Semiconductor, Thin Film Battery and, to a lesser extent HTS materials. Photonics (which includes solar) currently represents the largest market for our targets. Thin Film Battery is a developing market where manufacturers of batteries use our targets to produce very small power supplies with small quantities of stored energy. Semiconductor is a developing market. We hired additional marketing staff during late 2006 to develop opportunities in this market, and we added to our sales staff in late 2007 for the purpose of focusing on opportunities for our products in the Solar industry. We also added staff to our Technology group during the second half of 2007 for the development of innovative products.

Executive Summary

For the six months ended June 30, 2008, we had revenues of $3,231,453. This was a decrease of $2,626,298, or 44.8%, compared to the six months ended June 30, 2007. The decrease in revenues can be attributed to a reduction in the cost of a high value raw material. We anticipate that the cost of this high value raw material will continue to be lower for 2008 compared to 2007. Also, as disclosed on Form 8-K dated February 21, 2008, one of our largest customers notified us that its orders for 2008 will be significantly less than 2007. This is due to the customer’s improved utilization of targets in their manufacturing process coupled with lower planned inventory levels. Late in the second quarter of 2008 this customer began to increase its orders on certain targets. We anticipate an increase in revenues during the last half of 2008 compared to the first half of 2008.

Reflecting positive benefits from product mix, gross profit declined only 10.8% to $866,872 for the first half of 2008 from $971,748 for the first half of 2007. The decrease was attributable to higher depreciation expense related to investments made to develop new markets and the decrease in revenue mentioned above. Gross margin increased to 26.8% of total revenues for the first six months of 2008 from 16.6% for the same period in 2007.

For the second quarter of 2008 gross profit was $437,847 compared to $429,025 for the first quarter of 2008. This is an increase of 2.1% even though revenues decreased 11.4% during the same period. Gross margin increased to 28.9% for the second quarter of 2008 from 25.0% for the first quarter of 2008. The increase in gross profit and gross margin can be attributed to the product mix.

For the six months ended June 30, 2008, we had net loss applicable to common shares of $187,245 compared to net income of $156,695 for the same period in 2007. This decrease can be largely attributed to additional operating expenses of approximately $196,000 and the decrease in revenue along with the depreciation expense increase mentioned above. We continued to invest in R&D, marketing, and sales to take advantage of current and future market opportunities. During the past 21 months we have been actively marketing to additional customers in select markets. This has resulted in trial and qualification orders that were shipped to customers in the semiconductor and solar industries during the first half of 2008 which totaled approximately 13% of our revenues. We have received additional trial orders that should ship during the second half of 2008.

We received notification during the second quarter of 2007 from the Department of Energy of a Notice of Financial Assistance Award in the amount of $97,900. This award provides support for Phase I of a Small Business Innovative Research (SBIR) award entitled “Flux Pinning Additions to Increase Jc Performance in BSCCO-2212 Round Wire for Very High Field Magnets.” The work on the contract was completed during the first quarter of 2008.

We received notification during the second quarter of 2008 from the Department of Energy of a Notice of Financial Assistance Award in the amount of $99,961. This award provides support for Phase I of a Small Business Innovative Research (SBIR) award entitled “Homogenous BSCCO-2212 Round Wires for Very High Field Magnet Applications.” The work on the contract will begin during the third quarter of 2008.

RESULTS OF OPERATIONS

Six months ended June 30, 2008 (unaudited) compared to six months ended June 30, 2007 (unaudited):

Revenues

Revenues for the six months ended June 30, 2008 were $3,231,453 compared to $5,857,751, for the same period last year, a decrease of $2,626,298 or 44.8%. The revenue decline can be attributed to the ongoing purchase of raw materials whose prices have historically experienced periods of significant fluctuation. Cost changes for this high value raw material are fully reflected in the final selling price which insulates us from market risk associated with the raw material. We anticipate the cost of this high value raw material will continue to be lower in 2008 compared to 2007. This will result in lower revenues. As disclosed on Form 8-K dated February 21, 2008, one of our largest customers notified us that its orders for 2008 will be significantly less than 2007. This is due to the customer’s improved utilization of targets in their manufacturing process coupled with lower planned inventory levels. This customer has placed orders for the third quarter of 2008 and we anticipate an increase in revenues during the last half of 2008 compared to the first half of 2008.

Gross Profit

Gross profit for the six months ended June 30, 2008 was $866,872 compared to $971,748 for the six months ended June 30, 2007. The decrease in gross profit was attributable to the decrease in revenue and higher depreciation expense related to investments made to develop new markets. Gross margin as a percentage of revenue was 26.8% for the six months ended June 30, 2008 versus 16.6% for the six months ended June 30, 2007. The increase in gross margin was primarily due to less cost related to the high value raw material which has low margins and product mix.

Marketing and Sales Expense

Marketing and Sales expense for the six months ended June 30, 2008 increased 30.9% to $272,032 from $207,851 for the same period in 2007. The increase was due to the addition of staff and increased travel. We added a sales engineer late in 2007 to focus marketing efforts on applications in Thin Film Solar which is a rapidly expanding industry.

General and Administrative Expense

General and administrative expense for the six months ended June 30, 2008 increased to $510,461 from $456,312 for the six months ended June 30, 2007, or 11.9%. The increase was due to an increase in staff and professional fees.

Research and Development Expense

Research and development expense for the first six months of 2008 was $222,719 compared to $145,037 for the same period in 2007, an increase of 53.6%. The increase was due to increased staff and continued development efforts associated with applications in Photonic, Solar, Thin Film Battery and Semiconductor markets.

Interest Income and Expense

Interest income was $14,175 and $26,988 for the six months ended June 30, 2008 and 2007, respectively.

Interest expense was $51,997 and $24,116 for the six months ended June 30, 2008 and 2007, respectively. The increase was due to additional capital lease obligations incurred for the purchase of production equipment for increased production capacity.

(LOSS) INCOME APPLICABLE TO COMMON SHARES

(Loss) income applicable to common shares was $(187,245), or $(0.05) per basic common share compared to $156,695, or $0.05 per basic common share for the six months ended June 30, 2008 and 2007, respectively. Basic net (loss) income per common share before dividends on preferred stock was $(0.05) and $0.05 for the six months ended June 30, 2008 and 2007, respectively. The income applicable to common shares includes net (loss) income from operations and the accretion of Series B preferred stock dividends. Dividends on the Series B preferred stock accrue at 10% annually on the outstanding shares. Dividends accrued during the six months ended June 30, 2008 and 2007, was $12,283 and $12,592, respectively.

Basic net loss for the six months ended June 30, 2008 was $0.05 per common share based on 3,500,419 weighted average shares outstanding compared to income of $0.05 per common share based on 3,451,032 weighted average shares outstanding for the six months ended June 30, 2007.

Diluted net loss per common share for the six months ended June 30, 2008 was $0.05 based on 3,500,419 weighted average shares outstanding compared to income of $0.04 per share based on 4,240,350 weighted average shares outstanding for the six months ended June 30, 2007. All outstanding common stock equivalents were anti-dilutive for the three months and six months ended June 30, 2008 due to the net loss.

The following schedule represents our outstanding common shares during the period of 2008 through 2018 assuming all outstanding stock options and stock warrants are exercised during the year of expiration. If each shareholder exercises his or her options or warrants, it could increase our common shares by 1,154,807 to 4,714,878 by December 31, 2018. Exercise prices for options and warrants range from $1.00 to $4.00 at June 30, 2008. Assuming all such options and warrants are exercised in the year of expiration, the effect on shares outstanding is illustrated as follows:

	Options and Warrants due to expire		Potential Shares Outstanding

2008		0		3,560,071
2009		160,418		3,720,489

LIQUIDITY AND WORKING CAPITAL

At June 30, 2008, working capital was $1,347,791 compared to $1,590,286 at June 30, 2007. We used cash from operations of approximately $153,000 for the six months ended June 30, 2008. We provided cash from operations of approximately $752,000 for the six months ended June 30, 2007. Significant non-cash items including depreciation, accretion and amortization, stock based compensation expense, inventory reserve on excess and obsolete inventory, and provision for doubtful accounts were approximately $221,000 and $173,000, respectively, for the six months ended June 30, 2008 and 2007. Accounts receivable, inventory, prepaid expenses and other assets increased approximately $1,558,000 for the six months ended June 30, 2008. Accounts receivable, inventory, prepaid expenses and other assets decreased approximately $243,000 for the six months ended June 30, 2007. Accounts payable, accrued expenses and customer deposits increased approximately $1,360,000 for the six months ended June 30, 2008 and approximately $171,000 for the same period in 2007. Cash of approximately $75,000 and $63,000 was used for investing activities for the six months ended June 30, 2008 and 2007, respectively. The amounts invested were used to purchase machinery and equipment for increased production capacity and new product lines.

Cash of approximately $108,000 was used for financing activities during the six months ended June 30, 2008. Cash payments to third parties for capital lease obligations approximated $142,000. Proceeds received from the exercise of common stock warrants were approximately $68,000. Proceeds received from the exercise of common stock options were $10,250. Cash payments for services provided for the registration of common stock were approximately $20,000. A cash payment related to Series B preferred stock dividend was approximately $25,000.

We incurred new capital lease obligations of approximately $889,000 for new production equipment during the first six months ended June 30, 2007.

RISK FACTORS

We desire to take advantage of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The following factors, as well as the factors listed under the caption “Risk Factors” in our Form 10-KSB filed with the Securities and Exchange Commission on March 9, 2008, have affected or could affect our actual results and could cause such results to differ materially from those expressed in any forward-looking statements made by us. Investors should consider carefully these risks and speculative factors inherent in and affecting our business and an investment in our common stock.

Historically we have experienced significant operating losses and may continue to do so in the future.

While we have had profitable operations in 2007 and 2006, profits have not been consistent and we have financed the losses primarily from additional investments and loans by our major shareholders and private offerings of common stock and warrants to purchase common stock.

Item 2.

Management's Discussion and Analysis of Financial Condition and Results of Operations (continued)

We cannot assure you, however, that we will be able to raise additional capital in the future to fund our operations. While certain of our major shareholders have advanced funds in the form of secured debt, subordinated debt, accounts payable and guaranteeing bank debt in the past, there is no commitment by these individuals to continue funding us or guaranteeing bank debt in the future. We will continue to seek new financing or equity financing arrangements. However, we cannot be certain that it will be successful in efforts to raise additional funds.

Off Balance Sheet Arrangements

We have no off balance sheet arrangements including special purpose entities.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported in the Financial Statements and accompanying notes. Note 2 to the Financial Statements in our Annual Report on Form 10-KSB for the year ended December 31, 2007 describes the significant accounting policies and methods used in the preparation of the Financial Statements. Estimates are used for, but not limited to, accounting for the allowance for doubtful accounts, inventory allowances, property and equipment depreciable lives, patents and licenses useful lives, and assessing changes in which impairment of certain long-lived assets may occur. Actual results could differ from these estimates. The following critical accounting policies are impacted significantly by judgments, assumptions and estimates used in the preparation of the Financial Statements. The allowance for doubtful accounts is based on our assessment of the collectibility of specific customer accounts and the aging of the accounts receivable. If there is a deterioration of a major customer’s credit worthiness or actual defaults are higher than our historical experience, our estimates of the recoverability of amounts due us could be adversely affected. Inventory purchases and commitments are based upon future demand forecasts. If there is a sudden and significant decrease in demand for our products or there is a higher risk of inventory obsolescence because of rapidly changing technology and customer requirements, we may be required to increase our inventory allowances and our gross margin could be adversely affected. Depreciable and useful lives estimated for property and equipment, licenses and patents are based on initial expectations of the period of time these assets and intangibles will benefit us. Changes in circumstances related to a change in our business, change in technology or other factors could result in these assets becoming impaired, which could adversely affect the value of these assets.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation under the supervision and with the participation of our management, our principal executive officer and principal financial officer have concluded that the disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended ("Exchange Act") were effective as of June 30, 2008 to ensure that information required to be disclosed in reports that are filed or submitted under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Item 4. Controls and Procedures (continued)

Inherent Limitations Over Internal Controls

Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements.

Management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods is subject to the risk that those internal controls may become inadequate because of changes in business conditions or that the degree of compliance with the policies or procedures may deteriorate.

Additionally, there were no changes in our internal controls that could materially affect our disclosure controls and procedures subsequent to the date of their evaluation, nor were there any material deficiencies or material weaknesses in our internal controls. As a result, no corrective actions were required.
