Our growth is fueled by an unwavering focus on the core of our business—designing and manufacturing high-quality medical products for critical, niche applications. By any financial measure, 2010 was an outstanding year. Compared to the prior year, we achieved an 8% organic increase in sales, with 40% of this increase originating outside of North America. Our profit margins also increased from 45% to 47%, while our operating costs remained flat. Diluted earnings per share increased by 19%, excluding a non-cash pre-tax pension termination charge of $.32 per share in 2009. Cash, short and long term investments increased by $5.3 million to $41.7 million. Finally, on top of $3.2 million in regular quarterly dividends, in 2010 our stockholders shared $18.1 million in special cash distributions. Investing for the Future Our strong 2010 performance is the result of exceedingly careful planning: We study opportunities in order to be in position to capitalize on them, and we anticipate obstacles in order to be prepared to overcome them. This approach has helped us tame the inherent risks of the business cycle, guiding us well through the past several years of economic turmoil. During those years, we chose to make significant investments in our people, facilities, and manufacturing technologies. These investments increased the diversity of our offerings, while raising the quality of our products and improv- ing our profit margins. Those results inspire us to remain relentless in seeking opportunities to improve ourselves, our processes, and our products—regard- less of the macroeconomic conditions. Innovation at the Foundation Level True innovation is an outcome of the close association of design and produc- tion. Creating high-quality, high-performance products requires both an understanding of the needs of our customers, as well as the knowledge we gain by facing day-to-day manufacturing challenges. The two are inextricably linked. For this reason, Atrion continues to conduct research and development at each of our three U.S. locations in order to create new products. In 2011 we plan to substantially add to our manufacturing capacity and increase automation at each of our three facilities. In fact, investments planned for the year should approach the combined total of such expendi- tures over the previous three years. These increases will come at a time when This approach has helped us tame the inherent risks of the business cycle, guiding us well through the past several years of economic turmoil. 2 ATRION 2010 ANNUAL REPORT we also expect to maintain higher levels of working capital, since our market- ing efforts continue to target the development of long-term contracts with significant domestic and international customers. Large customers typically require increased inventory levels as a safety stock, while international sales are traditionally associated with longer payment terms. This will produce a reversal of our 2010 experience, when we were able to reduce working capital despite the overall increase in sales. However, given our very strong financial position, we can readily fund the increased capital requirements. Prepared for Progress Looking ahead, we anticipate changes and uncertainty in our industry. One reason for this is the still-unclear impact of healthcare reform on hospital reimbursements. Hospitals ultimately consume the majority of our products; changes in their reimbursement structure therefore hold the potential to impact our results. Additionally, the United States Food and Drug Administra- tion is currently reviewing its process for approving medical devices, which could further lengthen the approval process and delay the introduction of new products. And, of course, the overall global economy remains unsettled. Despite these concerns, we plan to keep working quietly and intently, engi- neering innovations to broaden and improve our product offerings and to have the needed capacity to produce them. This should leave us prepared to meet the growing demand for medical services both domestically, as the uninsured gain greater access to healthcare, and also in developing countries where governments are allocating increasing resources to medical care. We will continue to devote our energy and attention to our customers, our products, and our employees, as well as to our duty to manage risk and deliver superior performance. We are grateful to our stockholders for their continued trust in our ability to do so, and to our employees whose hard work makes it all possible.

or the “Company”) develop and manufacture products primarily for medical applications. We market our products throughout the United States and internationally. Our customers include hospitals, distributors, and other manufacturers. Atrion Corpora- tion’s principal subsidiaries through which these operations are conducted are Atrion Medical Products, Inc., Halkey-Roberts Corporation and Quest Medical, Inc. Principles of Consolidation The consolidated financial statements include the accounts of Atrion Corporation and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Estimates 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 and disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amount of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Cash and Cash Equivalents Cash equivalents include cash on hand and in the bank as well as money market accounts and debt securities with original maturities of 90 days or less. Trade Receivables Trade accounts receivable are recorded at the original sales price to the customer. We maintain an allowance for doubtful accounts to reflect estimated losses resulting from the failure of customers to make required payments. On an ongoing basis, the collectability of accounts receivable is assessed based upon historical collection trends, current economic factors and the assessment of the collectability of specific accounts. We evaluate the collectability of specific accounts and determine when to grant credit to our customers using a combination of factors, including the age of the outstanding balances, evaluation of customers’ current and past financial condition, recent payment history, current economic environ- ment, and discussions with appropriate Company personnel and with the customers directly. Accounts are written off when we determine the receivable will not be collected. Investments Our investments consist of taxable high-grade corporate bonds and certificates of deposits. Our investment policy is to seek to preserve principal and maintain adequate liquidity while at the same time maximizing yields without significantly increasing risk. We are required to classify our investments as trading, available-for-sale or held-to-maturity. Our investments are accounted for as held-to-maturity since we have the positive intent and ability to hold these investments to maturity. These investments are reported at cost, adjusted for premiums and discounts that are recognized in interest income, using a method that approximates the effective interest method, over the period to maturity and unrealized gains and losses are excluded from earnings. We consider as current assets those investments which will mature in the next 12 months. The remaining investments are considered non-current assets. Notes to Consolidated Financial Statements ATRION 2010 ANNUAL REPORT 9 Inventories Inventories are stated at the lower of cost (including materials, direct labor and applicable overhead) or market. Cost is determined by using the first-in, first-out method. The follow- ing table details the major components of inventory (in thousands): December 31, 2010 2009 Raw materials $ 7,888 $ Work in process Finished goods 3,985 5,527 Total inventories $ 17,400 $ 8,541 4,078 6,056 18,675 Accounts Payable We reflect disbursements as trade accounts payable until such time as payments are presented to our bank for payment. At December 31, 2010 and 2009, disbursements totaling approximately $282,000 and $498,000, respectively, had not been presented for payment to our bank. Income Taxes We account for income taxes utilizing Accounting Standards Codification (ASC) 740, Income Taxes (“ASC 740”). ASC 740 requires the asset and liability method for the recording of deferred income taxes, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statement and the tax bases of assets and liabilities, as measured at current enacted tax rates. When appropriate, we evaluate the need for a valuation allowance to reduce deferred tax assets. ASC 740 also requires the accounting for uncertainty in income taxes recognized in an enterprise’s financial state- ments and prescribes a recognition threshold and measurement attributes of income tax positions taken or expected to be taken on a tax return. Under ASC 740, the impact of an uncertain tax position taken or expected to be taken on an income tax return must be recognized in the financial statements at the largest amount that is more-likely- than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more-likely- than-not of being sustained. Our uncertain tax positions are recorded as “Other non-current liabilities.” We classify interest expense on underpayments of income taxes and accrued penalties related to unrecognized tax benefits in the income tax provision. Property, Plant and Equipment Property, plant and equipment is stated at cost and depreci- ated using the straight-line method over the estimated useful lives of the related assets. Additions and improvements are capitalized, including all material, labor and engineering costs to design, install or improve the asset. Expenditures for repairs and maintenance are charged to expense as incurred. The following table represents a summary of property, plant and equipment at original cost (in thousands): Land Buildings Machinery and equipment Total property, plant and equipment December 31, 2010 2009 Useful Lives $ 5,260 $ 5,260 — 29,798 29,662 30-40 yrs 68,731 64,940 3-15 yrs $ 103,789 $ 99,862 Depreciation expense of $6,769,000, $6,820,000 and $6,055,000 was recorded for the years ended December 31, 2010, 2009 and 2008, respectively. Depreciation expense is recorded in either cost of goods sold or operating expenses based on the associated assets’ usage. Patents and Licenses Costs for patents and licenses acquired are determined at acquisition date. Patents and licenses are amortized over the useful lives of the individual patents and licenses, which are from 7 to 19 years. Patents and licenses are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Goodwill Goodwill represents the excess of cost over the fair value of tangible and identifiable intangible net assets acquired. Annual impairment testing for goodwill is done using a fair-value-based test. Goodwill is also reviewed whenever events or changes in circumstances indicate a change in value may have occurred. We have identified three reporting units where goodwill was recorded for purposes of testing goodwill impairment annually: (1) Atrion Medical Products, Inc., (2) Halkey-Roberts Corporation and (3) Quest Medical, Inc. The total carrying amount of goodwill in each of the years ended December 31, 2010, 2009 and 2008 was $9,730,000. 10 ATRION 2010 ANNUAL REPORT Notes to Consolidated Financial Statements Current Accrued Liabilities The items comprising current accrued liabilities are as follows (in thousands): December 31, 2010 2009 Accrued payroll and related expenses $ 3,833 $ 2,935 Accrued vacation Accrued professional fees Other accrued liabilities Total accrued liabilities 171 215 431 159 45 457 $ 4,650 $ 3,596 Revenues We recognize revenue when our products are shipped to our customers, provided an arrangement exists, the fee is fixed and determinable and collectability is reasonably assured. All risks and rewards of ownership pass to the customer upon shipment. Net sales represent gross sales invoiced to customers, less certain related charges, including discounts, returns and other allowances. Revenues are recorded exclusive of sales and similar taxes. Returns, discounts and other allowances have been insignificant historically. Shipping and Handling Policy Shipping and handling fees charged to customers are reported as revenue and all shipping and handling costs incurred related to products sold are reported as cost of goods sold. Research and Development Costs Research and development costs relating to the development of new products and improvements of existing products are expensed as incurred. Advertising Advertising production costs are expensed as incurred. Costs for print placement media are expensed in the period the advertising first appears. Total advertising expenses were approximately $117,000, $126,000 and $251,000 for the years ended December 31, 2010, 2009 and 2008, respectively. Stock-Based Compensation We have stock-based compensation plans covering certain of our officers, directors and key employees. As explained in detail in Note 8, we account for stock-based compensation utilizing the fair value recognition provisions of ASC 718, Compensation-Stock Compensa- tion, (“ASC 718”). Pension Plan We terminated our pension plan in 2007 and had settled all obligations under the plan, and no assets, liabilities or stock- holders equity accounts remained for the plan, as of December 31, 2009. Prior to final settlement in the fourth quarter of 2009, our pension plan benefits were expensed as applicable employ- ees earned benefits. The recognition of expenses was significantly impacted by estimates made by management, such as discount rates used to value certain liabilities and expected return on assets. We used third-party specialists to assist management in appropriately measuring the expense associated with our pension plan benefits. All unrecognized losses, net of tax, were recorded as accumulated other compre- hensive loss within stockholders’ equity. Comprehensive Income Comprehensive income includes net income plus other compre- hensive income, which for us in 2009 and 2008 consisted of the amortization of unrecognized pension gains and recogni- tion of losses as a result of pension plan settlement transactions. There were no comprehensive income items during 2010. New Accounting Pronouncements In October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force, which amends the criteria for when to evaluate individual delivered items in a multiple deliverable arrangement and how to allocate consideration received. This ASU is effective for fiscal years beginning on or after June 15, 2010. The adoption of the guidance on January 1, 2011 is not expected to have a material impact on our consolidated financial statements. From time to time, new accounting pronouncements appli- cable to us are issued by the FASB or other standards setting bodies, which we will adopt as of the specified effective date. Unless otherwise discussed, we believe the impact of recently issued standards that are not yet effective will not have a mate- rial impact on our consolidated financial statements upon adoption. Notes to Consolidated Financial Statements ATRION 2010 ANNUAL REPORT 11 Fair Value Measurements Accounting standards use a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers are: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists therefore requiring an entity to develop its own assumptions. As of December 31, 2010 and 2009, we held certain invest- ments that were required to be measured for disclosure purposes at fair value on a recurring basis. These investments are considered Level 2 assets. The fair value of our investments is estimated using recently executed transactions and market price quotations. At December 31, 2010 and 2009, the fair value of our investments approximated or exceeded the carrying value of the investments (see Note 2). The carrying values of our other financial instruments includ- ing cash and cash equivalents, money market accounts, accounts receivable, accounts payable, accrued liabilities, and accrued income and other taxes approximated fair value due to their liquid and short-term nature. Concentration of Credit Risk Financial instruments that potentially subject us to concentra- tions of credit risk consist primarily of cash, cash equivalents, investments, and accounts receivable. Our cash is held in high credit quality financial institutions. As of December 31, 2010, $3.6 million in cash and cash equiva- lents was maintained in two separate municipal money market mutual funds, and $7.1 million in cash and cash equivalents was maintained at two major financial institutions in the United States. At times, deposits held with financial institutions exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and, therefore, bear minimal risk. At December 31, 2010, our uninsured cash and cash equivalents totaled approximately $9.0 million. We have invested a portion of our cash in fully insured certificates of deposits and in debt instruments of corporations with strong credit ratings. For accounts receivable, we perform ongoing credit evalua- tions of our customers’ financial condition and generally do not require collateral. We maintain reserves for possible credit losses. As of December 31, 2010 and 2009, we had allow- ances for doubtful account balances of approximately $36,000 and $61,000, respectively. The carrying amount of the receivables approximates their fair value. Our largest customer accounted for 14.1%, 15.0% and 11.6% of operating revenues in 2010, 2009 and 2008, respec- tively. That same customer accounted for 16.2%, 16.1% and 12.8% of accounts receivable as of December 31, 2010, 2009 and 2008, respectively. No other customer exceeded 10% of our operating revenues for the years ended, or accounts receivable as of, December 31, 2010, 2009 or 2008. 12 ATRION 2010 ANNUAL REPORT Notes to Consolidated Financial Statements (2) Investments As of December 31, 2010 and 2009, we held certain invest- ments that were required to be measured for disclosure purposes at fair value on a recurring basis. These investments were considered Level 2 investments. We consider as current assets those investments which will mature in the next 12 months. The remaining investments are considered non-cur- rent assets. The amortized cost and fair value of our investments that are being accounted for as held-to-maturity securities, and the related gross unrealized gains and losses, were as follows as of the dates shown below (in thousands): (3) Patents and Licenses Purchased patents and licenses paid for the use of other entities’ patents are amortized over the useful life of the patent or license. The following tables provide information regarding patents and licenses (dollars in thousands): December 31, 2010 Weighted Average Original Life (years) Gross Carrying Amount Accumulated Amortization 14.76 $ 11,668 $ 10,419 Gross Unrealized December 31, 2009 Cost Gains Losses As of December 31, 2010 Fair Value Weighted Average Original Life (years) Gross Carrying Amount Accumulated Amortization 14.76 $ 11,668 $ 10,147 Short-term Investments: Corporate bonds $ 10,715 $ 178 $ — $ 10,893 Long-term Investments: Corporate bonds $20,291 $ 602 $ — $20,893 As of December 31, 2009 Short-term Investments: Corporate bonds $ 1,193 $ 8 $ — $ 1,201 Bank certificates of deposit 3,037 $ 4,230 $ — 8 — 3,037 — $ 4,238 Long-term Investments: Corporate bonds $ 11,477 $ 164 $ — $ 11,641 At December 31, 2010, the length of time until maturity of these securities ranged from one to 20 months. Aggregate amortization expense for patents and licenses was $272,000 for 2010, $343,000 for 2009 and $298,000 for 2008. Estimated future amortization expense for each of the years set forth below ending December 31, is as follows (in thousands): 2011 2012 2013 2014 2015 $ 272 $ 160 $ 160 $ 160 $ 160 (4) Line of Credit We have a revolving credit facility (“Credit Facility”) with a money center bank. Under the Credit Facility, we have a line of credit of $25 million which is secured by substantially all our inventories, equipment and accounts receivable. Interest under the Credit Facility is assessed at 30-day, 60-day or 90-day LIBOR, as selected by us, plus one percent (1.30 percent at December 31, 2010) and is payable monthly. We had no outstanding borrowings under the Credit Facility at December 31, 2010 or 2009. The Credit Facility expires November 12, 2012 and may be extended under certain circumstances. At any time during the term, we may convert any or all outstanding amounts under the Credit Facility to a term loan with a maturity of two years. Our ability to borrow funds under the Credit Facility from time to time is contingent on meeting certain covenants in the loan agreement, the most restrictive of which is the ratio of total debt to earnings before interest, income tax, depreciation and amortization. At December 31, 2010, we were in compliance with all financial covenants.

The basic-income-per-share amounts for 2008 shown above have been retrospectively recalculated to also reflect the inclusion of participating securities in the basic-income-per-share computation. Application of this treatment had an insignificant effect in all periods. Income- per-share amounts are computed independently for each quarter. As a result, the sum of the per-share amounts for each quarter may not equal the year-to-date amounts. Incremental shares from stock options, unvested restricted stock, restricted stock units and deferred stock units were included in the calculation of weighted average diluted shares outstanding using the treasury stock method. The computa- tion of weighted average diluted shares outstanding excludes options to purchase 16,000 shares of common stock for the year ended December 31, 2008, because the exercise price of those options was greater than the average market price, resulting in an anti-dilutive effect on diluted income per share. As of December 31, 2010 all of the unrecognized tax benefits, which were comprised of uncertain tax positions, would impact the effective tax rate if recognized. Unrecognized tax benefits that are affected by statutes of limitation that expire within the next 12 months are immaterial. We are subject to U.S. federal income tax as well as to income tax of multiple state jurisdictions. We have concluded all U.S. federal income tax matters for years through 2005. In January 2009, the Internal Revenue Service (“IRS”) began examining certain of our U.S. federal income tax returns for 2006, 2007 and 2008. To date, no proposed adjustments have been issued. All material state and local income tax matters have been concluded for years through 2006. We recognize interest and penalties, if any, related to unrecog- nized tax benefits in income tax expense. The liability for unrecognized tax benefits included accrued interest of $84,000, $61,000 and $73,000 at December 31, 2010, 2009 and 2008, respectively. Tax expense for the years ended December 31, 2010 and 2008 included net interest expense of $23,000 and $23,000, respectively. Tax expense for the year ended December 31, 2009 included a net interest benefit of $12,000. (6) Stockholders’ Equity Our Board of Directors has at various times authorized repurchases of our stock in open-market or negotiated transac- tions at such times and at such prices as management may from time to time decide. In 2010 we repurchased 9,995 shares in the open market. No repurchases were made in 2009 and 2008. As of December 31, 2010, authorization for the repurchase of up to an additional 58,105 shares remained. We have increased our quarterly cash dividend payments in September of each of the past three years. The quarterly dividend was increased to $.30 per share in September 2008, to $.36 per share in September 2009 and to $.42 in Septem- ber 2010. On January 29, 2010 and December 23, 2010 we made special cash dividend payments to stockholders of $6.00 and $3.00 per share, respectively. We have a Rights Plan, which is intended to protect the interests of stockholders in the event of a hostile attempt to take over the Company. The rights, which are not presently exercisable and do not have any voting powers, represent the right of our stockholders to purchase at a substantial discount, upon the occurrence of certain events, shares of our common stock or of an acquiring company involved in a business combination with us. This plan, which was adopted in August 2006, expires in August 2016. Notes to Consolidated Financial Statements ATRION 2010 ANNUAL REPORT 15 (8) Stock Plans At December 31, 2010, we had four stock-based compensation plans which are described more fully below. We account for our plans under ASC 718, and the disclosures that follow are based on applying ASC 718. ASC 718 requires that cash flows from the exercise of stock-based compensation resulting from tax benefits in excess of recognized compensation cost (excess tax benefits) be classified as financing cash flows. We recorded $1,239,000, $121,000 and $1,635,000 of such excess tax benefits as financing cash flows in 2010, 2009 and 2008, respectively. Our 1997 Stock Incentive Plan (the “1997 Plan”) provides for the grant to key employees of incentive and nonqualified stock options, stock appreciation rights, restricted stock and perfor- mance shares. In addition, under the 1997 Plan, outside directors (directors who are not employees of the Company or any subsidiary) each received automatic annual grants of nonquali- fied stock options to purchase 2,000 shares of common stock until 2005 when that plan was amended to provide that no additional stock options may be granted to outside directors thereunder. Under the 1997 Plan, 624,425 shares, in the aggregate, of common stock were reserved for grants. The purchase price of shares issued on the exercise of incentive options was required to be at least equal to the fair market value of such shares on the date of grant. The purchase price for shares issued on the exercise of nonqualified options and restricted and performance shares was fixed by the Compensation Committee of the Board of Directors. The options granted become exercis- able as determined by the Compensation Committee and expire no later than 10 years after the date of grant. Our Amended and Restated 2006 Equity Incentive Plan (the “2006 Plan”) provides for the grant to key employees, non- employee directors and consultants of incentive and nonqualified stock options, restricted stock, restricted stock units, deferred stock units, stock appreciation rights, performance shares and other stock-based awards. Under the 2006 Plan, 200,000 shares, in the aggregate, of common stock have been reserved for awards. The purchase price of shares issued on the exercise of options must be at least equal to the fair market value of such shares on the date of grant. The purchase price for restricted and performance shares is fixed by the Compensation Committee of the Board of Directors. The options granted become exercisable and expire as determined by the Compensa- tion Committee except that incentive options expire no later than 10 years after the date of grant. In May 2007, we adopted our Deferred Compensation Plan for Non-Employee Directors and 2,500 shares of our common stock were reserved for issuance thereunder. This plan, as amended (the “Deferred Compensation Plan”), allows our non-employee directors to elect to receive stock units in lieu of all or part of the cash fees they are receiving for their services as directors. On the first business day of each calendar year, each participating non-employee director is credited with a number of stock units equal to the cash fees such director has elected to forego for such year divided by the closing price of our common stock on the next preceding date on which shares of our stock were traded. The stock units are convertible to shares of our common stock on a one-for-one basis at a future date as elected in advance by the director, but no later than the January following the year in which the director ceases to serve on the Board of Directors. In May 2007, we also adopted our Non-Employee Director Stock Purchase Plan (as amended, the “Director Stock Purchase Plan”) pursuant to which our non-employee directors may elect to receive on the first business day of the calendar year fully-vested stock and restricted stock in lieu of some or all of their fees payable to them during such year. The foregone fees are converted into shares of fully-vested stock and restricted stock on the first business day of such calendar year based on the closing price of our common stock on the next preceding date on which shares of our stock were traded. The restricted stock vests in equal amounts on the first day of the next three succeeding calendar quarters, provided the non-employee director is then serving on our Board of Directors. At the time the Director Stock Purchase Plan was adopted, 2,500 shares were reserved for the issuance thereunder. As of December 31, 2010, there remained 1,363 shares reserved for issuance under such plan. Option transactions for the three years ended December 31, 2010 are as follows: Options outstanding at January 1, 2008 152,430 $ 33.96 Weighted Average Exercise Price Shares Granted in 2008 Exercised in 2008 Options outstanding at December 31, 2008 Granted in 2009 Exercised in 2009 Options outstanding at December 31, 2009 Granted in 2010 Exercised in 2010 Options outstanding at December 31, 2010 Exercisable options at December 31, 2008 Exercisable options at December 31, 2009 Exercisable options at December 31, 2010 16,000 $ 111.16 (69,430) $ 26.09 99,000 $ 51.96 — — (14,000) $ 42.29 85,000 $ 53.56 — — (62,792) $ 42.80 22,208 $ 83.96 70,500 $ 35.00 66,750 $ 41.49 14,208 $ 68.65 16 ATRION 2010 ANNUAL REPORT Notes to Consolidated Financial Statements All unvested options outstanding at December 31, 2010 are expected to vest. As of December 31, 2010, there remained 137,157 shares for which options may be granted in the future under the 1997 Plan and the 2006 Plan. The following table summarizes information about stock options outstanding at December 31, 2010: Range of exercise prices $26.13-$43.75 $111.06-$111.50 Options Outstanding Options Exercisable Number outstanding Weighted average remaining contractual life Weighted average exercise price Number exercisable Weighted average exercise price 8,000 14,208 22,208 2.8 years 2.4 years 2.5 years $ $ $ 35.73 111.12 83.96 8,000 6,208 14,208 $ $ $ 35.73 111.06 68.65 We estimate the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. None of our grants includes performance- based or market-based vesting conditions. The expected life represents the period that our stock-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The fair value of stock-based payments, funded with options, is valued using the Black-Scholes valuation method with a volatil- ity factor based on our historical stock trading history. We base the risk-free interest rate using the Black-Scholes valuation method on the implied yield currently available on U.S. Treasury securities with an equivalent term. We base the dividend yield used in the Black-Scholes valuation method on our dividend history. There were no options granted in 2010 and 2009. The fair value for the options granted in 2008 was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions for 2008: The weighted average grant date fair value of the options granted in 2008 was $24.31. The total intrinsic values of options exercised during 2010, 2009 and 2008 were $7.5 million, $.6 million and $7.0 million, respectively. The total intrinsic values of options outstanding and options currently exercisable at December 31, 2010, were $1.5 million and $1.2 million, respectively. During 2010, we made one award of restricted stock under the 2006 Plan. Under the terms of the award, the restrictions lapse over a two-year period. During 2008, we made one award of restricted stock under the 2006 Plan. Under the terms of the award, the restrictions lapse over a four-year period. In both cases, during the vesting period, holders of restricted stock have voting rights and earn dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Unvested shares are generally forfeited on termination of employment unless otherwise provided in the participant’s employment agreement or, in certain instances, if the termination is in connection with a change in control. Changes in restricted stock for the years ended December 31, 2008, 2009 and 2010 were as follows: Risk-free interest rate Dividend yield Volatility factor Expected life 2010 2009 2008 — — — — — — — — 2.70% 0.90% 25.00% 4 years Weighted Average Award Date Fair Value Per Share Shares Restricted stock at January 1, 2008 Granted in 2008 Vested in 2008 6,000 4,000 $ $ (1,500) $ Restricted stock at December 31, 2008 8,500 $ Granted in 2009 Vested in 2009 Restricted stock at December 31, 2009 Granted in 2010 Vested in 2010 — $ (2,500) $ 113.90 6,000 200 $ $ 91.46 150.23 (2,500) $ 144.94 71.86 111.06 71.86 90.31 — Restricted stock at December 31, 2010 3,700 $ 97.29 Notes to Consolidated Financial Statements ATRION 2010 ANNUAL REPORT 17 All shares of unvested restricted stock outstanding at December 31, 2010 are expected to vest. The total intrinsic value of unvested restricted stock awards at December 31, 2010, 2009 and 2008 was $556,000, $827,000 and $815,000, respectively. The total fair value of restricted stock vested during 2010, 2009 and 2008 was $362,000, $285,000 and $161,000, respectively. During 2009, restricted stock units were granted to certain employees under the 2006 Plan. All of these stock units are convertible to shares of stock on a one-for-one basis when the restrictions lapse, which is generally after a five-year period. Unvested stock units are forfeited on termination of employment. During the vesting period, holders of all restricted stock units earn dividends as additional units. During 2008, 2009 and 2010, certain non-employee directors elected to receive stock units in lieu of cash fees for their services as members of the Board of Directors. Changes in stock units for the years ended December 31, 2008, 2009 and 2010 were as follows: Restricted Stock Units Weighted Average Award Date Fair Value Per Unit Directors’ Stock Units Weighted Average Award Date Fair Value Per Unit Unvested stock units at January 1, 2008 10,010 $ 96.03 Granted in 2008 Vested in 2008 107 — $ 100.91 Unvested stock units at December 31, 2008 10,117 $ 96.09 Granted in 2009 Vested in 2009 825 — $ 102.08 Unvested stock units at December 31, 2009 10,942 $ 96.53 Granted in 2010 Forfeited in 2010 Vested in 2010 736 (469) — $ 157.43 $ 104.94 Unvested stock units at December 31, 2010 11,209 $ 100.19 — 341 (341) — 81 (81) — 60 (60) — $ $ $ $ $ $ 124.58 124.58 99.35 99.35 155.04 155.04 All unvested restricted stock units at December 31, 2010 are expected to vest. No restricted stock units vested during 2010. The total intrinsic value of all outstanding stock units which are not yet convertible at December 31, 2010, including 211 stock units held for the accounts of non-employee directors, was $2,049,000. The total fair value of directors’ stock units that vested was $9,000, $8,000 and $43,000 during 2010, 2009 and 2008, respectively. As of December 31, 2010, there remained 1,808 shares of common stock reserved for issuance at the end of deferral periods of stock units which may be credited in the future to non-employee directors. Compensation related to stock options is based on the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. Compensation related to restricted stock and restricted stock units is based on the fair market value of the stock on the date of the grant. These fair values are then amortized on a straight-line basis over the requisite service periods of the entire awards, which is generally the vesting period. For the years ended December 31, 2010, 2009 and 2008, we recorded share-based compensation expense as a “General and Administrative expense” in the amount of $606,000, $668,000 and $637,000, respectively, for all of the above mentioned share-based compensation arrangements. The total tax benefit recognized in the income statement from share-based compensation arrangements for the years ended December 31, 2010, 2009 and 2008, was $204,000, $226,000 and $218,000, respectively. Unrecognized compensation cost information for our various share-based compensation types is shown below as of December 31, 2010: Unrecognized Compensation Cost Weighted Average Remaining Years in Amortization Period Stock options Restricted stock Restricted stock units Total $ $ 130,000 232,000 311,000 673,000 1.7 1.7 1.8 We have a policy of utilizing treasury shares to satisfy stock option exercises, stock unit conversions and restricted stock awards. 18 ATRION 2010 ANNUAL REPORT Notes to Consolidated Financial Statements A summary of revenues by product line for 2010, 2009 and 2008 is as follows (in thousands): Fluid Delivery Cardiovascular Ophthalmology Other Total 2010 2009 2008 $ 39,442 $ 35,540 $ 32,209 31,280 19,370 18,477 29,051 19,452 16,600 29,263 15,192 19,231 $ 108,569 $ 100,643 $ 95,895 (11) Employee Retirement and Benefit Plans In September 2007, we terminated our pension plan that was maintained for all our regular employees except those of Quest Medical, Inc. and employees hired after May 2005. Prior to termination, our funding policy was to make the annual contributions required by applicable regulations and recommended by our actuary. We used a December 31 measurement date for the plan. Affected employees accrued pension benefits through December 31, 2007, but did not accrue any additional benefits under the plan after that date. However, participants continued to earn interest credits on their account balances until all our obligations to plan partici- pants were settled in October 2009. A pension termination settlement charge of $989,000 was recorded as a general and administrative expense in the fourth quarter of 2009 when all remaining plan obligations were settled. All assets remaining in the plan after the settlement was completed were trans- ferred to our 401(k) plan in December 2009. (9) Revenues From Major Customers We had one major customer which represented approximately $15.3 million (14.1 percent), $15.1 million (15.0 percent) and $11.1 million (11.6 percent) of our operating revenues during 2010, 2009 and 2008, respectively. (10) Industry Segment and Geographic Information We operate in one reportable industry segment: developing and manufacturing products primarily for medical applications and have no foreign operating subsidiaries. We have other product lines which include pressure relief valves and inflation systems, which are sold primarily to the aviation and marine industries. Due to the similarities in product technologies and manufacturing processes, these products are managed as part of our medical products segment. We recorded incidental revenues from our gaseous oxygen pipeline, which totaled approximately $961,000 in 2010, $958,000 in 2009 and $957,000 in 2008. Pipeline net assets totaled $1.9, $2.0 and $2.1 million at December 31, 2010, 2009 and 2008, respec- tively. Our revenues from sales to customers outside the United States totaled approximately 40 percent, 39 percent and 35 percent of our total revenues in 2010, 2009 and 2008, respectively. We have no assets located outside the United States.

Our pension plan assets at December 31, 2008 were invested in a money market account so that the settlement of the termination obligations could be completed after regulatory approvals were received. Final settlement of the plan termina- tion occurred in the fourth quarter of 2009 when benefit distributions totaling $3.7 million were made to participants. After all plan obligations were settled, the remaining plan assets of $263,000 were transferred to our 401(k) plan to be used for contributions and plan expenses. We sponsor a defined contribution 401(k) plan for all employees. Each participant may contribute certain amounts of eligible compensation. We make a matching contribution to the plan. Our contributions under this plan were $482,000, $499,000 and $498,000 in 2010, 2009 and 2008, respectively. 20 ATRION 2010 ANNUAL REPORT Notes to Consolidated Financial Statements (13) Subsequent Events We evaluated all events or transactions that occurred after December 31, 2010 and determined we did not have any material recognizable subsequent events. (12) Commitments and Contingencies From time to time and in the ordinary course of business, we may be subject to various claims, charges and litigation. In some cases, the claimants may seek damages, as well as other relief, which, if granted, could require significant expenditures. We accrue the estimated costs of settlement or damages when a loss is deemed probable and such costs are estimable, and accrues for legal costs associated with a loss contingency when a loss is probable and such amounts are estimable. Otherwise, these costs are expensed as incurred. If the estimate of a probable loss or defense costs is a range and no amount within the range is more likely, we accrue the mini- mum amount of the range. As of December 31, 2010, we had accrued $177,000 for legal fees and expenses that we expect to incur in connection with the litigation or arbitration of two such matters. We had a dispute which was favorably settled in the third quarter of 2007. This settlement was amended in December 2008. The amended settlement agreement provides that we may receive annual payments from 2009 through 2024. We have not recorded $7.0 million in potential future payments under this settlement as of December 31, 2010 due to the uncertainty of payment. We have arrangements with three of our executive officers pursuant to which the termination of their employment under certain circumstances would result in lump sum payments to them. Termination under such circumstances at December 31, 2010 could have resulted in payments aggregating $3.8 million.

Our audits of the basic consolidated financial statements included the financial statement schedule (not presented separately herein) listed in the index appearing under Item 15. Exhibits and Financial Statement Schedules. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Atrion Corporation and subsidiaries as of Decem- ber 31, 2010 and 2009, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material aspects, the informa- tion set forth therein. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Atrion Corporation’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 11, 2011 expressed an unqualified opinion. Grant Thornton LLP Dallas, Texas March 11, 2011 Report of Independent Registered Public Accounting Firm ATRION 2010 ANNUAL REPORT 23 MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2010 using the criteria set forth by the Committee of Sponsoring Organi- zations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on this assessment, our management concluded that, as of December 31, 2010, our internal control over financial reporting was effective. Our management, including our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. Our internal control system 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. All internal control systems, no matter how well designed, have inherent limitations. A system of internal control may become inadequate over time because of changes in conditions or deterioration in the degree of compliance with the policies or procedures. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 24 ATRION 2010 ANNUAL REPORT Management’s Report on Internal Control Over Financial Reporting REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Stockholders of Atrion Corporation We have audited Atrion Corporation’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Tread- way Commission (COSO). Atrion Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on Atrion Corporation’s internal control over financial report- ing based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understand- ing of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the com- pany’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, Atrion Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Atrion Corporation and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in stockholders’ equity and comprehensive income, and cash flows for each of the three years in the period ended Decem- ber 31, 2010, and our report dated March 11, 2011, expressed an unqualified opinion on those financial statements. Grant Thornton LLP Dallas, Texas March 11, 2011 Report of Independent Registered Public Accounting Firm ATRION 2010 ANNUAL REPORT 25 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview We develop and manufacture products, primarily for medical applications. We market components to other equipment manufacturers for incorporation in their products and sell finished devices to physicians, hospitals, clinics and other treatment centers. Our medical products primarily serve the fluid delivery, cardiovascular, and ophthalmology markets. Our other medical and non-medical products include instrumentation and disposables used in dialysis and valves and inflation devices used in marine and aviation safety products. In 2010 approxi- mately 40 percent of our sales were outside the United States. Our products are used in a wide variety of applications by numerous customers. We encounter competition in all of our markets and compete primarily on the basis of product quality, price, engineering, customer service and delivery time. Our strategy is to provide a broad selection of products in the areas of our expertise. Research and development efforts are focused on improving current products and developing highly-engineered products that meet customer needs in niche markets that are large enough to provide meaningful increases in sales. Proposed new products may be subject to regulatory clearance or approval prior to commercialization and the time period for introducing a new product to the marketplace can be unpredictable. We also focus on controlling costs by investing in modern manufacturing technologies and controlling purchasing processes. We have been successful in consistently generating cash from operations and have used that cash to reduce indebtedness, to fund capital expenditures, to make investment purchases, to repurchase stock and to pay dividends. Our strategic objective is to further enhance our position in our served markets by: Focusing on customer needs; Expanding existing product lines and developing new products; Maintaining a culture of controlling cost; and Preserving and fostering a collaborative, entrepreneurial management structure. For the year ended December 31, 2010, we reported revenues of $108.6 million, operating income of $31.0 million and net income of $21.0 million. Results of Operations Our net income was $21.0 million, or $10.38 per basic and $10.32 per diluted share, in 2010, compared to net income of $16.8 million, or $8.51 per basic and $8.36 per diluted share, in 2009 and net income of $15.7 million, or $7.99 per basic and $7.82 per diluted share, in 2008. The 2009 results included a $643,000 net of tax pension termination settlement charge, or $0.32 per diluted share, related to the termination of our defined benefit pension plans. Revenues were $108.6 million in 2010, compared with $100.6 million in 2009 and $95.9 million in 2008. The 8 percent revenue increase in 2010 over 2009 and the 5 percent revenue increase in 2009 over 2008 were generally attributable to higher sales volumes. Annual revenues by product lines were as follows (in thou- sands): Fluid Delivery Cardiovascular Ophthalmology Other Total 2010 2009 2008 $ 39,442 $ 35,540 $ 32,209 31,280 19,370 18,477 29,051 19,452 16,600 29,263 15,192 19,231 $ 108,569 $ 100,643 $ 95,895 26 ATRION 2010 ANNUAL REPORT Management’s Discussion and Analysis of Financial Condition and Results of Operations Our cost of goods sold was $57.7 million in 2010, compared with $55.3 million in 2009 and $53.3 million in 2008. Increased sales volume, increased material costs, and increased manufacturing overhead costs were the primary contributors to the 4 percent increase in cost of goods sold for 2010 over 2009 and the 4 percent increase in cost of goods sold for 2009 over 2008. Gross profit in 2010 increased $5.6 million to $50.9 million, compared with $45.3 million in 2009 and $42.5 million in 2008. Our gross profit was 47 percent of revenues in 2010, 45 percent of revenues in 2009 and 44 percent of revenues in 2008. The increases in gross profit percentage in each of 2010 and 2009 from the prior year was primarily due to a favorable product mix, improvements in manufacturing efficiencies and the impact of cost-savings projects. Operating expenses were $19.9 million in 2010, compared with $20.3 million in 2009 and $19.6 million in 2008. In 2010, decreases in selling expenses and research and development, or R&D, expenses were partially offset by increases in general and administrative, or G&A, expenses. R&D expenses decreased $385,000 in 2010 as compared to 2009 primarily related to decreased compensation costs and decreased outside services. R&D expenses consist primarily of salaries and other related expenses of the R&D personnel as well as costs associated with regulatory matters. In 2010, selling expenses decreased $282,000 primarily related to decreased compensation, advertising and promotional expenses. Selling expenses consist primarily of salaries, commissions and other related expenses for sales and marketing personnel, marketing, advertising and promotional expenses. In 2010, G&A expenses increased $277,000 over 2009 G&A expenses. G&A expenses in 2009 included a $989,000 settlement loss related to the termination of our defined benefit pension plans. Excluding the 2009 pension termination settlement charge; G&A expenses in 2010 increased $1.3 million, primarily as a result of increased compensation costs and outside services. G&A expenses consist primarily of salaries and other related expenses of administrative, executive and financial personnel and outside professional fees. In 2009, increases in G&A expenses and R&D expenses were partially offset by decreases in selling expenses. G&A expenses increased $297,000, excluding the previously mentioned pension termination settlement charge, primarily as a result of increased compensation costs, outside services and taxes partially offset by decreased travel costs. R&D expenses increased $85,000 in 2009 as compared to 2008 primarily as a result of increased compensation costs and increased outside services. In 2009, selling expenses decreased $618,000 primarily as a result of decreased compensation, travel, advertising and promotional expenses. Our operating income for 2010 was $31.0 million, compared with $25.0 million in 2009 and $23.0 million in 2008. The increase in 2010 gross profit in addition to the decrease in operating expenses described above were the major contribu- tors to the operating income improvement in 2010 compared to the previous year. The increase in gross profit partially offset by the increase in operating expenses described above were the major contributors to the operating income improvements in 2009 compared to the previous year. Our interest income for 2010 was $1.0 million compared with $578,000 in 2009 and $299,000 in 2008. The increases in 2010 and 2009 were primarily related to the increased level of cash and investments during 2010 and 2009. Results for 2010 were also favorably impacted by investing in bonds with slightly longer maturities and higher yields. Income tax expense in 2010 totaled $11.0 million, compared with $8.7 million in 2009 and $7.6 million in 2008. The effective tax rates for 2010, 2009 and 2008 were 34.5 percent, 34.2 percent and 32.7 percent, respectively. Benefits from tax incentives for domestic production and R&D expendi- tures totaled $977,000 in 2010, $776,000 in 2009 and $896,000 in 2008. Expenses from changes in uncertain tax positions totaled $255,000 in 2010, $143,000 in 2009 and $231,000 in 2008. We expect our effective tax rate for 2011 to be approximately 35.0 percent. Management’s Discussion and Analysis of Financial Condition and Results of Operations ATRION 2010 ANNUAL REPORT 27 Liquidity and Capital Resources We have a $25.0 million revolving credit facility with a money center bank to be utilized for the funding of operations and for major capital projects or acquisitions, subject to certain limitations and restrictions (see Note 4 of Notes to Consoli- dated Financial Statements). Borrowings under the credit facility bear interest that is payable monthly at 30-day, 60-day or 90-day LIBOR, as selected by us, plus one percent. We had no outstanding borrowings under our credit facility as of or for the years ended December 31, 2010 and December 31, 2009. The credit facility, which expires November 12, 2012, and may be extended under certain circumstances, contains various restrictive covenants, none of which is expected to impact our liquidity or capital resources. At December 31, 2010, we were in compliance with all financial covenants and had $25.0 million available for borrowing under the credit facility. We believe that the bank providing the credit facility is highly- rated and that the entire $25.0 million under the credit facility is currently available to us. If that bank were unable to provide such funds, we expect that we would still be able to fund operations. Capital expenditures for property, plant and equipment totaled $4.3 million in 2010, compared with $6.6 million in 2009 and $5.4 million in 2008. These expenditures were primarily for the addition of machinery and equipment. We expect 2011 capital expenditures, primarily machinery and equipment, to increase substantially over the average of the levels expended during each of the past three years. We paid cash dividends totaling $21.3 million, $2.6 million and $2.1 million during 2010, 2009 and 2008, respectively. In January 2010, our Board of Directors declared a special cash dividend of $6.00 per share on our outstanding common stock. This dividend which totaled $12.1 million was paid on January 29, 2010. In December 2010, our Board of Directors declared a special cash dividend of $3.00 per share on our outstanding common stock. This dividend which totaled $6.0 million was paid on December 23, 2010. We expect to fund future dividend payments with cash flows from operations. The table below summarizes debt, lease and other contractual obligations outstanding at December 31, 2010: At December 31, 2010, we had a total of $41.7 million in cash and cash equivalents, short-term investments and long-term investments, an increase of $5.3 million from December 31, 2009. The principal contributor to this increase was the cash generated by operating activities, which was partially offset by payments for acquisitions of property, plant and equipment and the payment of dividends. Payments Due by Period Contractual Obligations Total 2011 2012– 2013 2014 and thereafter (in thousands) Purchase Obligations $ 11,909 $ 11,828 Total $ 11,909 $ 11,828 $ $ 78 78 $ $ 3 3 In the current credit and financial markets, many companies are finding it difficult to gain access to capital resources. In spite of the current economic conditions, we believe that our cash, cash equivalents, short-term investments and long-term investments, cash flows from operations and available borrowings of up to $25.0 million under our credit facility will be sufficient to fund our cash requirements for at least the foreseeable future. We believe that our strong financial position would allow us to access equity or debt financing should that be necessary. Additionally, we expect that our cash and cash equivalents and investments, as a whole, will continue to increase in 2011. Off-Balance Sheet Arrangements We have no off-balance sheet financing arrangements. Cash flows provided by operations of $31.2 million in 2010 were primarily comprised of net income plus the net effect of non-cash expenses plus net changes in working capital items. Inventories, accounts payable and accrued liabilities were the primary contributors to the positive net change in working capital items. The change in inventories was primarily related to increased sales volumes during December 2010. The change in accounts payable and accrued liabilities was primarily related to increases in accrued compensation. At December 31, 2010, we had working capital of $44.2 million, including $10.7 million in cash and cash equivalents and $10.7 million in short-term investments. The $5.3 million decrease in working capital during 2010 was primarily related to decreases in cash and cash equivalents and inventories partially offset by increases in short-term investments. The net increase in cash and short-term investments was primarily related to amounts generated from operations. The decrease in inventories was primarily related to increased sales volumes at year end. Working capital items consisted primarily of accounts receivable, short-term investments, accounts payable, inventories and other current assets and other current liabilities. 28 ATRION 2010 ANNUAL REPORT Management’s Discussion and Analysis of Financial Condition and Results of Operations Impact of Inflation We experience the effects of inflation primarily in the prices we pay for labor, materials and services. Over the last three years, we have experienced the effects of moderate inflation in these costs. At times, we have been able to offset a portion of these increased costs by increasing the sales prices of our products. However, competitive pressures have not allowed for full recovery of these cost increases. New Accounting Pronouncements In October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force, which amends the criteria for when to evaluate individual delivered items in a multiple deliverable arrangement and how to allocate consideration received. This ASU is effective for fiscal years beginning on or after June 15, 2010. The adoption of the guidance on January 1, 2011 is not expected to have a material impact on our consolidated financial statements. From time to time, new accounting standards updates applicable to us are issued by the FASB, which we will adopt as of the specified effective date. Unless otherwise discussed, we believe the impact of recently issued standards updates that are not yet effective will not have a material impact on our consolidated financial statements upon adoption. Critical Accounting Policies The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. In the preparation of these financial statements, we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. We believe the following discussion addresses our most critical accounting policies and estimates, which are those that are most impor- tant to the portrayal of our financial condition and results and require management’s most difficult, subjective and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Actual results could differ significantly from those estimates under different assumptions and conditions. From time to time, we accrue legal costs associated with certain litigation. In making determinations of likely outcomes of litigation matters, we consider the evaluation of legal counsel knowledgeable about each matter, case law and other case-specific issues. We believe these accruals are adequate to cover the legal fees and expenses associated with litigating these matters. However, the time and cost required to litigate these matters as well as the outcomes of the proceedings may vary from what we have projected. We maintain an allowance for doubtful accounts to reflect estimated losses resulting from the failure of customers to make required payments. On an ongoing basis, the collectability of accounts receivable is assessed based upon historical collection trends, current economic factors and the assessment of the collectability of specific accounts. We evaluate the collectability of specific accounts and determine when to grant credit to our customers using a combination of factors, including the age of the outstanding balances, evaluation of customers’ current and past financial condition, recent payment history, current economic environment, and discussions with our personnel and with the customers directly. Accounts are written off when it is determined the receivable will not be collected. If circumstances change, our estimates of the collectability of amounts could be changed by a material amount. We are required to estimate our provision for income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax exposure, including assessing the risks associated with tax audits, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the balance sheet. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is more likely than not, do not establish a valuation allowance. In the event that actual results differ from these estimates, the provision for income taxes could be materially impacted. We assess the impairment of our long-lived identifiable assets, excluding goodwill which is tested for impairment as explained below, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. This review is based upon projections of anticipated future cash flows. Although we believe that our estimates of future cash flows are reasonable, different assumptions regarding such cash flows or future changes in our business plan could materially affect our evaluations. No such changes are anticipated at this time. We assess goodwill for impairment pursuant to ASC 350, Intangibles—Goodwill and Other, which requires that goodwill be assessed whenever events or changes in circumstances indicate that the carrying value may not be recoverable, or, at a minimum, on an annual basis by applying a fair value test. Management’s Discussion and Analysis of Financial Condition and Results of Operations ATRION 2010 ANNUAL REPORT 29 During 2008, 2009 and 2010, none of our critical accounting policy estimates required significant adjustments. We did not note any events or changes in circumstances indicating that the carrying value of material long-lived assets were not recoverable. Quantitative and Qualitative Disclosures About Market Risks Foreign Exchange Risk We are not exposed to material fluctuations in currency exchange rates because the payments from our international customers are received primarily in United States dollars. Principal and Interest Rate Risk Our cash equivalents and short-term and long-term invest- ments consist of money-market accounts and taxable high-grade corporate bonds. Our investment policy is to seek to manage these assets to achieve the goal of preserving principal, maintaining adequate liquidity at all times, and maximizing returns subject to established investment guide- lines. In general, the primary exposure to market risk is interest rate sensitivity. This means that a change in prevailing interest rates may cause the value of and the return on the investment to fluctuate. In recent years, there has been concern in the credit markets regarding the value of a variety of mortgage-backed securities and the resultant effect on various securities markets. We believe that our cash, cash equivalents, and investments do not have significant risk of default or illiquidity. However, our cash equivalents and investments may be subject to adverse changes in market value. Forward-looking Statements Statements in this Management’s Discussion and Analysis and elsewhere in this Annual Report that are forward-looking are based upon current expectations, and actual results or future events may differ materially. Therefore, the inclusion of such forward-looking information should not be regarded as a representation by us that our objectives or plans will be achieved. Such statements include, but are not limited to, our expectations regarding increases in our manufacturing capacity and equipment in 2011, increases in working capital levels, funding increased capital requirements, changes and uncertainly in the medical products industry, the effect of changes in reimbursement on financial results, the effect of regulatory changes on the approval process for the introduc- tion of new medical products, our plans to broaden and improve product offerings and to be in a position to meet demands for medical services, our efforts to manage risk and deliver superior performance, our research and development expenditures in 2011, our 2011 effective tax rate, our 2011 capital expenditures, funding future dividend payments with cash flows from operations, availability of equity and debt financing, our ability to meet our cash requirements for the foreseeable future, our ability to fund operations if the bank providing our credit facility were unable to lend funds to us and increases in 2011 in cash, cash equivalents and invest- ments. Words such as “expects,” “believes,” “anticipates,” “intends,” “should,” “plans,” and variations of such words and similar expressions are intended to identify such forward-look- ing statements. Forward-looking statements contained herein involve numerous risks and uncertainties, and there are a number of factors that could cause actual results or future events to differ materially, including, but not limited to, the following: changing economic, market and business condi- tions; acts of war or terrorism; the effects of governmental regulation; the impact of competition and new technologies; slower-than-anticipated introduction of new products or imple- mentation of marketing strategies; implementation of new manufacturing processes or implementation of new informa- tion systems; our ability to protect our intellectual property; changes in the prices of raw materials; changes in product mix; intellectual property and product liability claims and product recalls; the ability to attract and retain qualified personnel and the loss of any significant customers. In addition, assumptions relating to budgeting, marketing, product development and other management decisions are subjective in many respects and thus susceptible to interpretations and periodic review which may cause us to alter our marketing, capital expendi- tures or other budgets, which in turn may affect our results of operations and financial condition. 30 ATRION 2010 ANNUAL REPORT Management’s Discussion and Analysis of Financial Condition and Results of Operations SELECTED FINANCIAL DATA (in thousands, except per share amounts) Operating Results for the Year ended December 31, Revenues Operating income Income from continuing operations Net income Depreciation and amortization Per Share Data: Income from continuing operations, per diluted share Net income per diluted share Cash dividends per common share Average diluted shares outstanding Financial Position at December 31, Total assets Long-term debt 2010 2009 2008 2007 2006 $ 108,569 $ 100,643 $ 95,895 $ 88,540 $ 81,020 30,977 20,952 20,952 7,041 10.32 10.32 25,004a 16,843a 16,843a 7,163 8.36a 8.36a 22,973 15,667 15,667 6,353 7.82 7.82 20,195b 14,006b 14,006b 5,534 7.06b 7.06b $ 10.56 $ 1.32 $ 1.08 $ .88 $ 14,338 10,600 10,765 5,005 5.43 5.51 .74 2,030 2,015 2,004 1,985 1,953 $ 134,652 $ 132,749 $ 115,353 $ 99,313 $ 95,772 — — — — $ 11,399 a) Included a non-cash charge for the settlement of the 2007 termination of pension plans that subtracted $1.0 million from operating income, $643,000 from net income and $0.32 from net income per diluted share.
