GRIFFON CORPORATION AND SUBSIDIARIES ------------------------------------ NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ---------------------------------------------------- (Unaudited) (1) Basis of Presentation - --------------------- The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the 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 generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three-month and six-month periods ended March 31, 2003 are not necessarily indicative of the results that may be expected for the year ending September 30, 2003. The balance sheet at September 30, 2002 has been derived from the audited financial statements at that date. For further information, refer to the consolidated financial statements and footnotes thereto included in the company's annual report to shareholders for the year ended September 30, 2002. Effective October 1, 2001, the company adopted Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets," (SFAS 142). SFAS 142 addresses accounting and reporting for acquired goodwill. It eliminates the previous requirement to amortize goodwill and establishes new requirements with respect to the recognition and valuation of goodwill. With the assistance of a third-party valuation expert, the company ascertained the fair value of its reporting units as part of adopting SFAS 142 and determined that goodwill of the installation services segment was impaired pursuant to the new standard. Results for the six-month period ended March 31, 2002 include the related cumulative effect of a change in accounting principle in the amount of $24,118,000 (net of an income tax benefit of $2,457,000) to reflect the impairment. Recent accounting pronouncements: The Financial Accounting Standards Board has issued Interpretations Nos. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees including Indirect Guarantees of Indebtedness of Others" and 46, "Consolidation of Variable Interest Entities." Interpretation No. 45 elaborates on disclosures to be made by a guarantor in its financial statements about its obligations under certain guarantees that it has issued. As a part of some transactions, the company may provide routine indemnifications in which it retains certain environmental, tax and other liabilities whose terms range in duration and for which the company's ultimate obligation is not quantifiable. To date, the company has not made any significant payments in connection with such indemnifications. Interpretation No. 46 addresses consolidation of variable interest entities and related disclosure. A subsidiary of the company is a party to lease and other agreements with a variable interest entity for the purpose of renting one of the company's facilities which has a total cost of $10.5 million. The company does not anticipate incurring any liabilities in connection with such agreements beyond its obligations for rental payments pursuant to the lease. The company does not anticipate that adopting Interpretations Nos. 45 and 46 will have a material effect on results of operations or financial condition.

Statement of Financial Accounting Standards No. 123, "Accounting for Stock- Based Compensation", as amended by Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure", permits an entity to continue to account for employee stock-based compensation under APB Opinion No. 25, "Accounting for Stock Issued to Employees", or adopt a fair value based method of accounting for such compensation. The company has elected to continue to account for stock-based compensation under Opinion No. 25. Accordingly, no compensation expense has been recognized in connection with options granted. Had compensation expense for options granted been determined based on the fair value at the date of grant in accordance with Statement No. 123, the company's net income and earnings per share would have been as follows: Three Months Ended Six Months Ended March 31 March 31 ------------------ ---------------- 2003 2002 2003 2002 ---- ---- ---- ---- Net income(loss), as reported $ 4,617,000 $ 4,815,000 $15,537,000 $(8,721,000) Deduct total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects (653,000) (641,000) (1,279,000) (1,171,000) ----------- ----------- ----------- ----------- Pro forma net income $ 3,964,000 $ 4,174,000 $14,258,000 $(9,892,000) =========== =========== =========== =========== Earnings per share: Basic - as reported $.14 $.14 $.47 $(.26) ==== ==== ==== ===== Basic - pro forma $.12 $.13 $.43 $(.30) ==== ==== ==== ===== Diluted - as reported $.14 $.14 $.46 $(.25) ==== ==== ==== ===== Diluted - pro forma $.12 $.12 $.42 $(.28) ==== ==== ==== ===== (2) Inventories - ----------- Inventories, stated at the lower of cost (first-in, first-out or average) or market, are comprised of the following: March 31, September 30, 2003 2002 ------------ ------------- Finished goods......................... $ 46,558,000 $ 45,288,000 Work in process........................ 42,704,000 37,870,000 Raw materials and supplies............. 20,022,000 21,634,000 ----------- ------------ $109,284,000 $104,792,000 ============ ============

(3) Earnings per share (EPS) - ------------------------ Basic EPS is calculated by dividing income by the weighted average number of shares of common stock outstanding during the period. The weighted average number of shares of common stock used in determining basic EPS was 32,934,000 and 33,208,000 for the three months ended March 31, 2003 and 2002, respectively, and 33,028,000 and 33,132,000 for the six months ended March 31, 2003 and 2002, respectively. Diluted EPS is calculated by dividing income by the weighted average number of shares of common stock outstanding plus additional common shares that could be issued in connection with potentially dilutive securities. The weighted average number of shares of common stock used in determining diluted EPS was 34,009,000 and 35,276,000 for the three months ended March 31, 2003 and 2002, respectively and 34,025,000 and 34,924,000 for the six months ended March 31, 2003 and 2002, respectively, and reflects additional shares issuable in connection with stock option and other stock based compensation plans. Options to purchase approximately 1,656,425 and 1,857,650 shares of common stock were not included in the computations of diluted earnings per share for the three and six months ended March 31, 2003 because the effects would have been antidilutive. (4) Business segments - ----------------- The company's reportable business segments are as follows - Garage Doors (manufacture and sale of residential and commercial/industrial garage doors, and related products); Installation Services (sale and installation of building products primarily for new construction, such as garage doors, garage door openers, manufactured fireplaces and surrounds, and cabinets); Electronic Information and Communication Systems (communication and information systems for government and commercial markets) and Specialty Plastic Films (manufacture and sale of plastic films and film laminates for baby diapers, adult incontinence care products, disposable surgical and patient care products and plastic packaging).

(5) Comprehensive income - -------------------- Comprehensive income, which consists of net income (loss) and foreign currency translation adjustments, was $6.2 million and ($4.6) million for the three-month periods and $19.6 and $9.9 million for the six-month periods ended March 31, 2003 and 2002, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2003 Operating results (in thousands) by business segment were as follows for the three-month periods ended March 31: Segment Net Sales Operating Profit ----------------- ------------------ 2003 2002 2003 2002 ---- ---- ---- ---- Garage doors $ 82,886 $ 93,302 $ 2,966 $ 336 Installation services 66,672 63,520 528 721 Specialty plastic films 92,129 68,948 9,156 10,064 Electronic information and communication systems 40,612 46,675 2,894 3,086 Intersegment revenues (4,969) (5,137) - - -------- -------- ------- ------- $277,330 $267,308 $15,544 $14,207 ======== ======== ======= ======= Garage Doors - ------------ Net sales of the garage door segment decreased by $10.4 million or 11.2%. The decrease was primarily due to the 2002 divestiture of Atlas, an unprofitable commercial operation ($6.4 million) and the net effect ($4.0 million) of lower unit sales attributable to inclement weather conditions partly offset by favorable pricing and product mix. Operating profit of the garage doors segment increased $2.6 million compared to last year. The Atlas divestiture accounted for $1.6 million of the increase. Gross margin percentage increased to approximately 31.9% in 2003 from 29.1% last year. The increased margin was due primarily to the effect of the Atlas divestiture, improved pricing and product mix, and increased manufacturing efficiencies. Selling, general and administrative expenses decreased principally due to the Atlas divestiture and as a percentage of sales was 28.4% compared to 28.7% last year. Installation Services - --------------------- Net sales of the installation services segment increased by $3.2 million or 5.0% compared to last year. The increase was principally due to the segment's expanded product offering and increased market share, partly offset by the effect of inclement weather conditions. Operating profit of the installation services segment decreased $.2 million compared to last year. Gross margin percentage decreased to 26.7% from 27.3% last year. Selling, general and administrative expenses as a percentage of sales was 26.0% compared to 26.2% last year. The decreased profitability was principally due to costs incurred by the segment to adjust inventory levels and make structural changes in certain locations which have been unprofitable. Specialty Plastic Films - ----------------------- Net sales of the specialty plastic films segment increased $23.2 million or 33.6% compared to the prior year. Higher unit volume and product mix ($10 million), the effect of a weaker U.S. dollar on translated foreign sales ($8 million), the addition of the Brazilian operation in the latter half of fiscal 2002 ($3 million) and selling price adjustments to pass through raw material (resin) cost increases to customers ($2 million), were the principal reasons for the increase.

Operating profit of the specialty plastic films segment decreased $.9 million compared to last year. Gross margin percentage decreased to 22.0% from 27.3% last year. The lower margin percentage principally reflects the excess ($3.5 million) of raw material cost increases over related selling price adjustments. In addition to the effect of resin, segment operating profit was also affected by costs associated with manufacturing facility expansion for current and new products, and by the positive effect of increased volume and product mix, and exchange rate differences. Selling, general and administrative expenses as a percentage of sales was 12.2% compared to 12.4% last year. Electronic Information and Communication Systems - ------------------------------------------------ Net sales of the electronic information and communication systems segment decreased $6.1 million or 13.0% compared to last year. The decrease was primarily due to delays in anticipated awards of new orders. Operating profit of the electronic information and communication systems segment decreased $.2 million. The decrease is principally attributable to the sales decrease and higher research and development expenditures. Gross margin percentage increased to 27.2% from 24.2% last year due primarily to manufacturing efficiencies and lower margins last year in connection with certain development phase programs. Selling, general and administrative expenses as a percentage of sales was 20.9% compared to 17.8% due to the sales decrease. SIX MONTHS ENDED MARCH 31, 2003 Operating results (in thousands) by business segment were as follows for the six-month periods ended March 31: Net Sales Operating Profit ----------------- ------------------ 2003 2002 2003 2002 ---- ---- ---- ---- Garage doors $196,349 $213,039 $13,883 $ 9,581 Installation services 138,992 134,630 2,207 3,105 Specialty plastic films 179,471 141,514 19,822 19,884 Electronic information and communication systems 76,373 92,362 4,616 5,526 Intersegment revenues (11,701) (12,335) - - -------- -------- ------- ------- $579,484 $569,210 $40,528 $38,096 ======== ======== ======= ======= Garage Doors - ------------ Net sales of the garage doors segment decreased by $16.7 million or 7.8% compared to last year. The decrease was principally due to the Atlas divestiture ($11.6 million) and the net effect ($5.1 million) of lower unit volumes attributable to inclement weather partly offset by favorable pricing and product mix. Operating profit of the garage doors segment increased approximately $4.3 million compared to last year. The Atlas divestiture accounted for $2.3 million of the increase. Gross margin percentage increased to 32.3% in 2002 from 29.9% last year. The increased margin was due primarily to the Atlas divestiture, improved pricing and product mix, and manufacturing efficiencies. Selling, general and administrative expenses as a percentage of sales was 25.2% compared to 25.4% last year.

Installation Services - --------------------- Net sales of the installation services segment increased by $4.4 million or 3.2% compared to last year. The increase was principally due to the segment's expanded product offering and increased market share, partly offset by the effect of winter weather conditions. Operating profit of the installation services segment decreased $.9 million compared to last year. Gross margin percentage was 27.0% compared to 27.5% last year. Selling, general and administrative expenses as a percentage of sales was 25.5% compared to 25.2% last year. The decreased profitability was principally due to a lag in adjusting labor levels as sales softened at the end of the first quarter, and costs to adjust inventory levels and make structural changes in certain locations which have been unprofitable. Specialty Plastic Films - ----------------------- Net sales of the specialty plastic films segment increased $38.0 million or 26.8% compared to the prior year. Increased unit volume and product mix ($16 million), the effect of a weaker U.S. dollar on translated foreign sales ($13 million), the addition of the Brazilian operation ($6 million) and selling price adjustments to pass raw material cost increases to customers ($3 million) were the principal reasons for the increase. Operating profit of the specialty plastic films segment was approximately the same as last year. Gross margin percentage decreased to 23.1% from 25.9% last year. The lower margin percentage was principally due to the excess ($4.4 million) of raw material cost increases over related selling price adjustments. In addition to the effect of resin, segment operating profit was also affected by costs associated with manufacturing facility expansion for current and new products, and by the positive effect of increased volume and product mix, and exchange rate differences. Selling, general and administrative expenses as a percentage of sales was 12.2% compared to 11.7% last year. The increase was due to higher freight and administrative costs associated with the segment's European operation. Electronic Information and Communication Systems - ------------------------------------------------ Net sales of the electronic information and communication systems segment decreased $16.0 million or 17.3% compared to last year. The decrease was primarily due to delays in anticipated awards of new orders. Operating profit of the electronic information and communication systems segment decreased $.9 million compared to last year. The decrease is principally attributable to the sales decrease and increased research and development expenditures. Gross margin percentage increased to 26.3% from 22.6% last year due primarily to manufacturing efficiencies and lower margins last year in connection with certain development phase programs. Selling, general and administrative expenses as a percentage of sales was 21.1% compared to 16.9% last year due to the sales decrease. Net Interest Expense - -------------------- Net interest expense decreased by $.3 million compared to last year due to the effect of debt repayments and lower interest rates.

LIQUIDITY AND CAPITAL RESOURCES Cash flow generated by operations for the six months ended March 31, 2003 was $12.5 million compared to $44.0 million last year and working capital was $196.9 million at March 31, 2003. Operating cash flows decreased compared to last year due primarily to changes in operating assets and current liabilities. During the six months ended March 31, 2003, the company paid $13.1 million for the balance of the Brazilian operation's purchase price which was funded by bank borrowings. The company also had capital expenditures of approximately $22.1 million, principally by the specialty plastic films segment made in connection with increasing production capacity and for capital programs to support new opportunities with its major customers. Financing cash flows principally consisted of net bank borrowings of approximately $6.6 million, treasury stock purchases of $6.9 million and distributions to minority shareholders of $5.1 million. Additional purchases of the company's Common Stock under its stock buyback program will be made, depending upon market conditions, at prices deemed appropriate by management. At March 31, 2003, future minimum payments under noncancellable operating leases and payments to be made for notes payable and maturities of long-term debt over the next five years are as follows (000's omitted): Operating Debt Year Leases Repayments Total ---- --------- ---------- ----- 2004 $21,200 $ 6,300 $27,500 2005 15,700 9,300 25,000 2006 10,300 2,900 13,200 2007 7,400 9,600 17,000 2008 3,500 58,800 62,300 The $58.8 million of debt repayments reflected as payable in 2008 is primarily due to the scheduled expiration of the company's revolving credit agreement. The company anticipates that all or a substantial portion of that amount will be refinanced. Anticipated cash flows from operations, together with existing cash, bank lines of credit and lease line availability, should be adequate to finance presently anticipated working capital and capital expenditure requirements and to repay debt as it matures. ACCOUNTING POLICIES AND PRONOUNCEMENTS Critical Accounting Policies - ---------------------------- The company's significant accounting policies are set forth in Note 1 of Notes to Consolidated Financial Statements in the company's annual report to shareholders for the year ended September 30, 2002. The following discussion of critical accounting policies addresses those policies that require management judgment and estimates and are most important in determining the company's operating results and financial condition. The company recognizes revenues for most of its operations when title and the risks of ownership pass to its customers. Provisions for estimated losses resulting from the inability of our customers to remit payments are recorded in the company's consolidated financial statements. Judgement is required to estimate the ultimate realization of receivables. The company's electronic information and communication systems segment does a significant portion of its business under long-term contracts with government agencies. This unit generally recognizes contract-related revenue and profit using the percentage of completion method of accounting, which relies primarily on estimates of total expected contract costs. The company follows this method since reasonably dependable estimates of costs applicable to various elements of a contract can be made. Since the financial reporting of these contracts depends on estimates, recognized revenues and profit are

subject to revisions as contracts progress to completion. Contract cost estimates are generally updated quarterly. Revisions in revenue and profit estimates are reflected in the period in which the circumstances requiring the revision become known. Provisions are made currently for anticipated losses on uncompleted contracts. Inventory is stated at the lower of cost (principally first-in, first-out) or market. Inventory valuation requires the company to use judgment to estimate any necessary allowances for excess, slow-moving and obsolete inventory, which estimates are based on assessments about future demands, market conditions and management actions. Recent Accounting Pronouncements - -------------------------------- The Financial Accounting Standards Board has issued a number of other Financial Accounting Standards and Interpretations. See Note 1 of Notes to Condensed Consolidated Financial Statements for a discussion of these pronouncements. The company does not anticipate that adopting these pronouncements, where applicable, will have a material effect on results of operations or financial condition. FORWARD-LOOKING STATEMENTS All statements other than statements of historical fact included in this report, including without limitation statements regarding the company's financial position, business strategy, and the plans and objectives of the company's management for future operations, are forward-looking statements. When used in this report, words such as "anticipate", "believe", "estimate", "expect", "intend" and similar expressions, as they relate to the company or its management, identify forward-looking statements. Such forward-looking statements are based on the beliefs of the company's management, as well as assumptions made by and information currently available to the company's management. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors, including but not limited to, business and economic conditions, competitive factors and pricing pressures, capacity and supply constraints. Such statements reflect the views of the company with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to the operations, results of operations, growth strategy and liquidity of the company. Readers are cautioned not to place undue reliance on these forward-looking statements. The company does not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect future events or circumstances or to reflect the occurrence of unanticipated events. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK Management does not believe that there is any material market risk exposure with respect to derivative or other financial instruments that is required to be disclosed.
