NOTE 1 – DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

About Griffon Corporation

Griffon Corporation (the “Company” or “Griffon”) is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital.

Headquartered in New York, N.Y., the Company was founded in 1959 and is incorporated in Delaware. Griffon is listed on the New York Stock Exchange and trades under the symbol GFF.

On September 5, 2017, Griffon announced it would explore strategic alternatives for Clopay Plastic Products Company, Inc. ("PPC") and on November 16, 2017, announced it entered into a definitive agreement to sell PPC to Berry Global Group, Inc. (NYSE:BERY) ("Berry") for $475 million in cash. The transaction is subject to regulatory approval and customary closing conditions, and is expected to close in the first quarter of calendar 2018. As a result, Griffon classified the results of operations of the PPC business as discontinued operations in the Consolidated Statements of Operations for all periods presented and classified the related assets and liabilities associated with the discontinued operations as held for sale in the consolidated balance sheets. All results and information presented exclude PPC unless otherwise noted. PPC is a global leader in the development and production of embossed, laminated and printed specialty plastic films for hygienic, health-care and industrial products and sells to some of the world's largest consumer products companies. See Note 14, Discontinued Operations.

On October 2, 2017, Griffon acquired ClosetMaid LLC ("ClosetMaid"). ClosetMaid, founded in 1965, is a leading North American manufacturer and marketer of closet organization, home storage, and garage storage products, and sells to some of the largest home center retail chains, mass merchandisers, and direct-to-builder professional installers in North America. ClosetMaid's accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations are included in the Company’s consolidated financial statements from the date of acquisition of October 2, 2017. See Note 3, Acquisitions.

Griffon currently conducts its operations through two reportable segments:

• Home & Building Products (“HBP”) consists of three companies, The AMES Companies, Inc. (“AMES”), Clopay Building Products Company, Inc. (“CBP”) and ClosetMaid LLC ("ClosetMaid"):

  • AMES, founded in 1774, is the leading US manufacturer and a global provider of long-handled tools and landscaping products for homeowners and professionals.

  • CBP, since 1964, is a leading manufacturer and marketer of residential and commercial garage doors and sells to professional dealers and some of the largest home center retail chains in North America.

  • ClosetMaid, founded in 1965, is a leading North American manufacturer and marketer of closet organization, home storage, and garage storage products, and sells to some of the largest home center retail chains, mass merchandisers, and direct-to-builder professional installers.

• Telephonics Corporation ("Telephonics"), founded in 1933, is recognized globally as a leading provider of highly sophisticated intelligence, surveillance and communications solutions for defense, aerospace and commercial customers.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by US GAAP for complete financial statements. As such, they should be read together with Griffon’s Annual Report on Form 10-K for the year ended September 30, 2017 , which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year.

The condensed consolidated balance sheet information at September 30, 2017 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2017 .

The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated on consolidation.

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of assets and liabilities of discontinued operations, acquisition assumptions used and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates.

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

NOTE 2 – FAIR VALUE MEASUREMENTS

The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit and variable rate debt is based upon current market rates.

Applicable accounting guidance establishes a fair value hierarchy requiring the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows:

• Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets.

• Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

• Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

6

The fair values of Griffon’s 2022 senior notes approximated $1,020,000 on December 31, 2017 . Fair values were based upon quoted market prices (level 1 inputs).

On January 17, 2017, Griffon's 4% convertible subordinated notes settled for a total of $173,855 . The total settlement value for the convertible notes was based on the sum of the daily Volume Weighted Average Price multiplied by the conversion rate over a 40-day observation period (level 1 inputs). The settlement value was split between $125,000 in cash and $48,858 , or 1,954,993 shares, of common stock issued from treasury.

Insurance contracts with values of $3,000 at December 31, 2017 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets on the Consolidated Balance Sheets.

Items Measured at Fair Value on a Recurring Basis

At December 31, 2017 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $3,352 ( $2,824 cost basis), were included in Prepaid and other current assets on the Consolidated Balance Sheets. Realized and unrealized gains and losses on trading securities are included in Other income in the Consolidated Statements of Operations and Comprehensive Income (Loss).

In the normal course of business, Griffon’s operations are exposed to the effects of changes in foreign currency exchange rates. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. During the quarter ended December 31, 2017, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade and inter-company liabilities payable in US dollars.

At December 31, 2017 , Griffon had $15,000 and $1,422 of Australian dollar and British Pound Sterling contracts, respectively, at a weighted average rate of $1.28 and $0.74 , respectively, which qualified for hedge accounting. These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Accumulated other comprehensive income (loss) ("AOCI") and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred gains of $130 ( $42 , net of tax) at December 31, 2017 and a loss of $7 was recorded in COGS during the quarter ended December 31, 2017 for all settled contracts. All contracts expire in 15 to 179 days.

At December 31, 2017 , Griffon had $4,129 of Canadian dollar contracts at a weighted average rate of $1.25 . The contracts, which protect Canadian operations from currency fluctuations for US dollar based purchases, do not qualify for hedge accounting. For the quarter ended December 31, 2017 , a fair value gain of $237 was recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). Realized losses of $29 were recorded in Other income during the quarter ended December 31, 2017 for all settled contracts. All contracts expire in 28 to 238 days.

NOTE 3 – ACQUISITIONS

Griffon accounts for acquisitions under the acquisition method, in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition using a method substantially similar to the goodwill impairment test methodology (level 3 inputs). The operating results of the acquired companies are included in Griffon’s consolidated financial statements from the date of acquisition; in each instance, Griffon is in the process of finalizing the initial purchase price allocation.

On November 6, 2017, AMES acquired Harper Brush Works (“Harper”), a division of Horizon Global, for approximately $5,000 . Harper is a leading U.S. manufacturer of cleaning products for professional, home, and industrial use. The acquisition will broaden AMES’ long-handled tool offering in North America to include brooms, brushes, and other cleaning tools and accessories.

On October 2, 2017, Griffon Corporation completed the acquisition of ClosetMaid, a market leader of home storage and organization products, for approximately $185,700 , inclusive of post-closing adjustments, or $165,000 net of the estimated present value of tax benefits under the current tax law. There is no other contingent consideration arrangement relative to the acquisition of ClosetMaid. ClosetMaid adds to Griffon's Home and Building Products segment, complementing and diversifying Griffon's portfolio of leading consumer brands and products. During the quarter ended December 31, 2017, SG&A and Cost of goods and services included acquisition costs of $1,612 and $1,500 , respectively. ClosetMaid is part of the HBP segment.

ClosetMaid's accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations are included in the Company’s consolidated financial statements from the date of acquisition

7

of October 2, 2017. The Company has recorded a preliminary allocation of the purchase price to the Company’s tangible and identifiable intangible assets acquired and liabilities assumed based on their fair market values (level 3 inputs) at the acquisition date. The excess of the purchase price over the fair value of the net tangible and intangible assets was recorded as goodwill and is deductible for tax purposes. Goodwill recognized at the acquisition date represents the other intangible benefits that the Company will derive from the ownership of ClosetMaid, however, such intangible benefits do not meet the criteria for recognition of separately identifiable intangible assets.

The following unaudited proforma summary from continuing operations presents consolidated information as if the Company acquired ClosetMaid on October 1, 2016:

Proforma For the three months ended December 31, 2016 (unaudited)
Revenue $ 429,178
Income from continuing operations 7,980

Griffon did not include any material, nonrecurring proforma adjustments directly attributable to the business combination included in the proforma revenue and earnings. These proforma amounts have been compiled by adding the historical results from continuing operations of Griffon, restated for classifying the results of operations of the PPC business as a discontinued operation, to the historical results of ClosetMaid after applying Griffon’s accounting policies and the following proforma adjustments:

• Additional depreciation and amortization that would have been charged assuming the preliminary fair value adjustments to property, plant, and equipment, and intangible assets had been applied from October 1, 2016.

• Elimination of intercompany interest income recorded on ClosetMaid’s financial statements earned on an intercompany receivable due from ClosetMaid’s former parent.

• Additional interest and related expenses from the add-on offering of $275,000 aggregate principal amount of 5.25% senior notes due 2022 that Griffon used to acquire ClosetMaid.

• Removal of $600 of restructuring costs from ClosetMaid's historical results.

• The consequential tax effects of the above adjustments using a 59% tax rate.

The calculation of the preliminary purchase price allocation, which is pending finalization of tax-related items and completion of the related final valuation, is as follows:

Cash and cash equivalents $
Accounts receivable 32,234
Inventories 28,772
Property, plant and equipment 48,260
Goodwill 66,147
Intangible assets 72,465
Other current and non-current assets 3,852
Total assets acquired 257,729
Accounts payable and accrued liabilities 63,281
Long-term liabilities 8,719
Total liabilities assumed 72,000
Total $ 185,729

8

The amounts assigned to goodwill and major intangible asset classifications, all of which are tax deductible, for the ClosetMaid acquisition are as follows:

Goodwill $ 66,147 Average Life (Years) — N/A
Indefinite-lived intangibles 48,920 N/A
Definite-lived intangibles 23,545 18
Total goodwill and intangible assets $ 138,612

On September 29, 2017, AMES Australia completed the acquisition of Tuscan Landscape Group Pty, Ltd. ("Tuscan Path") for approximately $18,000 (AUD 22,250 ). Tuscan Path is a leading Australian provider of pots, planters, pavers, decorative stone, and garden decor products. The acquisition of Tuscan Path broadens AMES' outdoor living and lawn and garden business, and will strengthen AMES' industry leading position in Australia. The purchase price was primarily allocated to intangible assets of AUD 3,900 and inventory and accounts receivable of AUD 7,900 .

On July 31, 2017, The AMES Companies, Inc. acquired La Hacienda Limited, a leading United Kingdom outdoor living brand of unique heating and garden decor products, for approximately $11,400 (GBP 9,175 ), including an approximate contingent earn out payment of $790 (GBP 600 ). The acquisition of La Hacienda broadens AMES' global outdoor living and lawn and garden business and supports AMES' UK expansion strategy. The purchase price allocation was primarily allocated to intangible assets of approximately GBP 3,100 .

On December 30, 2016, AMES Australia acquired Hills Home Living ("Hills") for approximately $6,051 (AUD 8,400 ). The purchase price has been allocated to acquired assets and assumed liabilities and primarily consists of inventory, tooling and identifiable intangible assets, including trademarks, intellectual property and customer relationships.

NOTE 7 – INCOME TAXES

On December 22, 2017, the "Tax Cuts and Jobs Act" ("TCJA") was signed into law, significantly impacting several sections of the Internal Revenue Code. ASC 740, Accounting for Income Taxes , requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions, January 1, 2018. Though certain key aspects of the TCJA are effective January 1, 2018 and have an immediate accounting effect, other significant provisions are not effective or may not result in accounting effects for September 30 fiscal year companies until October 1, 2018.

Given the significance of the TCJA, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period”. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared or analyzed.

Among the significant changes to the U.S. Internal Revenue Code, the TCJA lowers the U.S. federal corporate income tax rate (“Federal Tax Rate”) from 35% to 21% effective January 1, 2018. The Company will compute its income tax expense for the September 30, 2018 fiscal year using a blended Federal Tax Rate of 24.5% . The 21% Federal Tax Rate will apply to fiscal years ending September 30, 2019 and each year thereafter.

The Company has recorded provisional amounts for the effects of the TCJA where accounting is not complete but a reasonable estimate has been determined. The company recorded a $23,941 benefit on the revaluation of deferred tax liabilities as a provisional amount for the re-measurement of deferred tax assets and liabilities, as well as an amount for deductible executive compensation expense, both of which have been reflected in the tax benefit for the quarter ended December 31, 2017.

A reasonable estimate cannot yet be made and therefore taxes are reflected based on the law in effect prior to the enactment of the Tax Cuts and Jobs Act for the impact of the one-time mandatory repatriation transition tax on the net accumulated earnings and profits of a U.S. taxpayer’s foreign subsidiaries, bonus depreciation expensing for qualified property placed in service after September 27, 2017 and the impact on state income taxes.

The provisional amounts incorporate assumptions made based upon the Company’s current interpretation of the TCJA and may change as the Company receives additional clarification and implementation guidance.

In accordance with SAB 118 adjustments recorded to the provisional amounts will be reflected within the measurement period through the quarter ended December 31, 2018 and will be included in income from continuing operations and net income as an adjustment to tax expense.

In the quarter ended December 31, 2017, the Company recognized a tax benefit of $24,904 on a Loss before taxes from continuing operations of $2,073 , compared to a tax benefit of $2,613 on Income before taxes from continuing operations of $4,431 in the comparable prior year quarter.

The quarters ended December 31, 2017 and 2016 tax rates included net tax benefits that affect comparability of $23,018 and $4,421 , respectively. The current year quarter ended December 31, 2017 included net tax benefits from the December 22, 2017 tax reform bill primarily from approximately $23,941 related to revaluation of deferred tax liabilities. The prior year quarter ended December 31, 2016 included discrete benefits from the adoption of Financial Accounting Standards Board guidance which requires the Company to recognize excess tax benefits from the vesting of equity awards within income tax expense. Excluding these tax items, the effective tax rates for the quarters ended December 31, 2017 and 2016 were 35.4% and 40.8% , respectively.

(a) On October 2, 2017, in an unregistered offering through a private placement under Rule 144A, Griffon completed the add-on offering of $275,000 principal amount of its 5.25% senior notes due 2022, at 101.00% of par, to Griffon's previously issued $125,000 principal amount of its 5.25% senior notes due 2022, at 98.76% of par, completed on May 18, 2016 and $600,000 5.25% senior notes due 2022, at par, completed on February 27, 2014 (collectively the “Senior Notes”). As of December 31, 2017 , outstanding Senior Notes due totaled $1,000,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the $275,000 add-on offering were used to acquire ClosetMaid with the remaining proceeds used to pay down outstanding loan borrowings under Griffon's revolving credit facility (the "Credit Agreement"). The net proceeds of the previously issued $125,000 add-on offering were used to pay down outstanding revolving loan borrowings under the Credit Agreement.

The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On December 18, 2017, Griffon commenced an offer to exchange all of the $275,000 Senior Notes issued on October 2, 2017 for substantially identical Senior Notes registered under the Securities Act of 1933. On July 20, 2016 and June 18, 2014, Griffon exchanged all of the $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of the Senior Notes approximated $1,020,000 on December 31, 2017 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $275,000 senior notes, Griffon capitalized $8,434 of underwriting fees and other expenses; Griffon capitalized $3,016 of underwriting fees and other expenses in connection with the $125,000 senior notes; and Griffon capitalized $10,313 in connection with the previously issued $600,000 senior notes. All capitalized fees will amortize over the term of the notes.

(b) On March 22, 2016, Griffon amended the Credit Agreement to increase the credit facility from $250,000 to $350,000 , extend its maturity date from March 13, 2020 to March 22, 2021 and modify certain other provisions of the facility. On October 2, 2017, Griffon further amended the Credit Agreement in association with the ClosetMaid acquisition to modify the net leverage covenant through the quarter ended March 31, 2019. The facility includes a letter of credit sub-facility with a limit of $50,000 and a multi-currency sub-facility of $50,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.25% for base rate loans and 2.25% for LIBOR loans. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon's material domestic subsidiaries securing a limited amount of the debt under the Credit Agreement relating to Griffon's Employee Stock Ownership Plan ("ESOP") ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (e) below). At December 31, 2017 , under the Credit Agreement, there were $147,743 in outstanding borrowings; standby letters of credit were $14,938 ; and $187,319 was available, subject to certain loan covenants, for borrowing at that date.

(c) On December 21, 2009, Griffon issued $100,000 principal amount of 4% convertible subordinated notes due 2017 (the “2017 Notes”). On July 14, 2016, Griffon announced that it would settle, upon conversion, up to $125,000 of the conversion value of the 2017 Notes in cash, with amounts in excess of $125,000 , if any, to be settled in shares of Griffon common stock. On January 17, 2017, Griffon settled the convertible debt for $173,855 with $125,000 in cash, utilizing borrowings under the Credit Agreement, and $48,858 , or 1,954,993 shares, of common stock issued from treasury.

(d) In September 2015 and March 2016, Griffon entered into mortgage loans in the amounts of $32,280 and $8,000 , respectively. The mortgage loans are secured by four properties occupied by Griffon's subsidiaries. The loans mature in September 2025 and April 2018, respectively, are collateralized by the specific properties financed and are guaranteed by Griffon. The loans bear interest at a rate of LIBOR plus 1.50% . At December 31, 2017 , mortgage loans outstanding relating to continuing operations was $22,743 , net of issuance costs.

(e) In August 2016, Griffon’s ESOP entered into an agreement that refinanced the existing ESOP loan into a new Term Loan in the amount of $35,092 (the "Agreement"). The Agreement also provided for a Line Note with $10,908 available to purchase shares of Griffon common stock in the open market. During 2017, Griffon's ESOP purchased 621,875 shares of common stock for a total of $10,908 or $17.54 per share, under a borrowing line that has now been fully utilized. On June 30, 2017,

14

the Term Loan and Line Note were combined into a single Term Loan. The Term Loan bears interest at LIBOR plus 2.50% . The Term Loan requires a quarterly principal payment of $569 with a balloon payment due at maturity on March 22, 2020. As of December 31, 2017 , $41,827 , net of issuance costs, was outstanding under the Term Loan. The Term Loan is secured by shares purchased with the proceeds of the loan and with a lien on a specific amount of Griffon assets (which lien ranks pari passu with the lien granted on such assets under the Credit Agreement) and is guaranteed by Griffon.

(f) Two Griffon subsidiaries have capital leases outstanding for real estate located in Troy, Ohio and Ocala, Florida. The leases mature in 2021 and 2022 , respectively, and bear interest at fixed rates of approximately 5.0% and 8.0% , respectively. The Troy Ohio lease is secured by a mortgage on the real estate and is guaranteed by Griffon. The Ocala, Florida lease contains two five -year renewal options. At December 31, 2017 , $9,606 was outstanding, net of issuance costs.

(g) In November 2012, Garant G.P. (“Garant”) entered into a CAD $15,000 ( $11,901 as of December 31, 2017 ) revolving credit facility. The facility accrues interest at LIBOR (USD) or the Bankers Acceptance Rate (CDN) plus 1.3% per annum ( 2.98% LIBOR USD and 2.78% Bankers Acceptance Rate CDN as of December 31, 2017 ). The revolving facility matures in October 2019. Garant is required to maintain a certain minimum equity. At December 31, 2017 , there were no borrowings under the revolving credit facility with CAD 15,000 ( $11,901 as of December 31, 2017) available for borrowing.

In July 2016, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries ("Griffon Australia") entered into an AUD 30,000 term loan and an AUD 10,000 revolver. The term loan refinanced two existing term loans and the revolver replaced two existing lines. In December 2016, the amount available under the revolver was increased from AUD 10,000 to AUD 20,000 and, in March 2017, the term loan commitment was increased by AUD 5,000 to AUD 33,500 . In September 2017, the term commitment was increased by AUD 15,000 to AUD 46,750 . The term loan requires quarterly principal payments of AUD 1,250 plus interest, with a balloon payment of AUD 37,125 due upon maturity in June 2019, and accrues interest at Bank Bill Swap Bid Rate “BBSY” plus 2.00% per annum ( 3.84% at December 31, 2017 ). As of December 31, 2017, the term loan had an outstanding balance of AUD 44,625 ( $34,765 as of December 31, 2017 ). The revolving facility matures in November 2018, but is renewable upon mutual agreement with the bank, and accrues interest at BBSY plus 2.0% per annum ( 3.70% at December 31, 2017 ). At December 31, 2017, the revolver had an outstanding balance of AUD 6,000 ( $4,675 at December 31, 2017). The revolver and the term loan are both secured by substantially all of the assets of Griffon Australia and its subsidiaries. Griffon guarantees the term loan. Griffon Australia is required to maintain a certain minimum equity level and is subject to a maximum leverage ratio and a minimum fixed charges cover ratio.

(h) Other long-term debt consists primarily of a loan with the Pennsylvania Industrial Development Authority, with the balance consisting of capital leases.

At December 31, 2017 , Griffon and its subsidiaries were in compliance with the terms and covenants of all credit and loan agreements.

NOTE 9 — SHAREHOLDERS’ EQUITY

During the first quarter of 2018, the Company paid a quarterly cash dividend of $0.07 per share. During 2017, the Company paid quarterly cash dividends of $0.06 per share, totaling $0.24 per share for the year. Dividends paid on shares in the ESOP were used to offset ESOP loan payments and recorded as a reduction of debt service payments and compensation expense. A dividend payable was established for the holders of restricted shares; such dividends will be released upon vesting of the underlying restricted shares.

On January 30, 2018, the Board of Directors declared a quarterly cash dividend of $0.07 per share, payable on March 22, 2018 to shareholders of record as of the close of business on February 22, 2018.

Compensation expense for restricted stock is recognized ratably over the required service period based on the fair value of the grant, calculated as the number of shares granted multiplied by the stock price on the date of grant and, for performance shares, the likelihood of achieving the performance criteria. Compensation cost related to stock-based awards with graded vesting, generally over a period of three to four years, is recognized using the straight-line attribution method and recorded within SG&A expenses.

On January 29, 2016, shareholders approved the Griffon Corporation 2016 Equity Incentive Plan ("Incentive Plan") under which awards of performance shares, performance units, stock options, stock appreciation rights, restricted shares, restricted stock units, deferred shares and other stock-based awards may be granted. On January 31, 2018, shareholders approved Amendment No. 1 to the Incentive Plan pursuant to which, among other things, 1,000,000 shares were added to the Incentive Plan. Options granted under the Incentive Plan may be either “incentive stock options” or nonqualified stock options, generally expire ten years after the date of grant and are granted at an exercise price of not less than 100% of the fair market value at the date of grant. The maximum number of shares of common stock available for award under the Incentive Plan is 3,350,000 ( 600,000 of which may

15

be issued as incentive stock options), plus (i) any shares reserved for issuance under the 2011 Equity Incentive Plan as of the effective date of the Incentive Plan, and (ii) any shares underlying awards outstanding on such effective date under the 2011 Incentive Plan that are canceled or forfeited. As of December 31, 2017 , there were 305,512 shares available for grant; after giving effect to Amendment No. 1 to the Incentive Plan, there would have been 1,260,622 shares available for grant as of such date, contemplating 44,890 of restricted share awards granted on January 31, 2018.

All grants outstanding under former equity plans will continue under their terms; no additional awards will be granted under such plans.

During the first quarter of 2018, Griffon granted 1,008,756 shares of restricted stock and restricted stock units. This included 480,756 shares of restricted stock and restricted stock units, subject to certain performance conditions, with vesting periods of three years , with a total fair value of $9,980 , or a weighted average fair value of $20.76 per share. This also included 528,000 shares of restricted stock granted to two senior executives with a vesting period of four years and a two year post-vesting holding period, subject to the achievement of certain absolute and relative performance conditions relating to the price of Griffon's common stock. So long as the minimum performance condition is attained, the amount of shares that can vest will range from 384,000 to 528,000 . The total fair value of these restricted shares is approximately $7,008 , or a weighted average fair value of $13.27 .

For the quarters ended December 31, 2017 and 2016, stock based compensation expense totaled $2,555 and $2,452 , respectively.

During the quarter ended December 31, 2017 , 191,332 shares, with a market value of $4,332 or $22.64 per shares were withheld to settle employee taxes due to the vesting of restricted stock, and were added to treasury.

On December 21, 2009, Griffon issued $100,000 principal amount of 4% convertible subordinated notes due 2017 (the “2017 Notes”). On July 14, 2016, Griffon announced that it would settle, upon conversion, up to $125,000 of the conversion value of the 2017 Notes in cash, with amounts in excess of $125,000 , if any, to be settled in shares of Griffon common stock. On January 17, 2017, Griffon settled the convertible debt for $173,855 with $125,000 in cash, utilizing borrowing under the Credit Agreement, and $48,858 , or 1,954,993 shares of common stock issued from treasury.

On August 3, 2016, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this share repurchase program, the Company may purchase shares in the open market, including pursuant to a 10b5-1 plan, or in privately negotiated transactions. There were no repurchases under this program during the quarter ended December 31, 2017. As of December 31, 2017 , $49,437 remains under the August 3, 2016 Board authorization.

From August 2011 to December 31, 2017 , Griffon repurchased 15,984,854 shares of common stock, for a total of $211,621 or $13.24 per share, under Board authorized repurchase programs.

In addition to repurchases under Board authorized programs, on December 10, 2013, Griffon repurchased 4,444,444 shares of its common stock for $50,000 from GS Direct, L.L.C. (“GS Direct”), an affiliate of The Goldman Sachs Group, Inc.

NOTE 10 – EARNINGS PER SHARE (EPS)

Basic EPS (and diluted EPS in periods when a loss exists) was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that were issued in connection with stock based compensation and upon the settlement of the 2017 convertible notes.

The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share:

Three Months Ended December 31, — 2017 2016
Weighted average shares outstanding - basic 41,923 39,336
Incremental shares from stock based compensation 1,413 1,922
Convertible debt matured 2017 1,054

Prior to settlement, Griffon had the intent and ability to settle the principal amount of the 2017 Notes in cash, and as such, the issuance of shares related to the principal amount of the 2017 Notes did not affect diluted shares.

NOTE 11 – BUSINESS SEGMENTS

Griffon’s reportable segments from continuing operations are as follows:

• HBP is a leading manufacturer and marketer of residential and commercial garage doors to professional dealers and to some of the largest home center retail chains in North America; a global provider of long-handled tools and landscaping products for homeowners and professionals; and a leading North American manufacturer and marketer of closet organization, home storage, and garage storage products to home center retail chains, mass merchandisers, and direct-to builder professional installers.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(US dollars and non US currencies in thousands, except per share data)

(Unaudited)

(Unless otherwise indicated, references to years or year-end refer to Griffon’s fiscal period ending September 30)

As a result of the recent passing of our Chairman of the Board, who participated in a Supplemental Executive Retirement Plan relating to his tenure as Chief Executive Officer (a position from which he retired in 2008), the pension benefit liability was reduced by $13,715 at December 31, 2017, with the offset, net of tax, recorded in Other Comprehensive Income.

NOTE 13 – RECENT ACCOUNTING PRONOUNCEMENTS

Issued but not yet effective accounting pronouncements

In May 2017, the FASB issued guidance to address the situation when a company modifies the terms of a stock compensation award previously granted to an employee. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The new guidance is effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires companies to retrospectively present the service cost component of net periodic benefit cost for pension and retiree medical plans along with other compensation costs in operating income and present the other components of net periodic benefit cost below operating income in the income statement. The guidance also allows only the service cost component of net periodic benefit cost to be eligible for capitalization within inventory or fixed assets on a prospective basis. This guidance is effective, and should be applied retroactively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The new guidance is effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In January 2017, the FASB issued guidance that simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those periods and will be effective for the Company beginning in 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In January 2017, the FASB issued guidance that clarifies the definition of a business, which will impact many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The new standard is intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods and will be effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In August 2016, the FASB issued guidance on the Statement of Cash Flows Classification of certain cash receipts and cash payments (a consensus of the FASB Emerging Issues Task Force). This guidance addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance will be effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In February 2016, the FASB issued guidance on lease accounting requiring lessees to recognize a right-of-use asset and a lease liability for long-term leases. The liability will be equal to the present value of lease payments. This guidance must be applied using a modified retrospective transition approach to all annual and interim periods presented and is effective for the Company

20

beginning in 2020. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures.

In May 2014, the FASB issued guidance on revenue from contracts with customers. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved, in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. This guidance permits the use of either the retrospective or cumulative effect transition method and is effective for the Company beginning in 2019; early adoption is permitted beginning in 2018. The Company has commenced its initial assessment to assess the impact, if any, the new revenue standard will have on the Company’s consolidated financial statements. During this initial assessment, the Company has identified certain differences that will likely have the most impact; however, how significant of an impact cannot be determined during this phase of the Company’s implementation process. These differences relate to the new concepts of variable consideration, consideration payable and the focus on control to determine when and how revenue should be recognized (i.e. point in time versus over time). The FASB has also issued the following additional guidance clarifying certain issues on revenue from contracts with customers; Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients and Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing. The Company expects to complete its initial assessments by the end of the third quarter of 2018 and expects to finalize its implementation process prior to the adoption of the new revenue standard on October 1, 2018.

The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements, and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.

NOTE 14 – DISCONTINUED OPERATIONS

PPC

On September 5, 2017, Griffon announced it would explore strategic alternatives for PPC and on November 16, 2017, announced it entered into a definitive agreement to sell PPC to Berry for $475 million in cash. The transaction is subject to regulatory approval and customary closing conditions, and is expected to close in the first quarter of calendar 2018. As a result, Griffon classified the results of operations of the PPC business as discontinued operations in the Consolidated Statements of Operations for all periods presented and classified the related assets and liabilities associated with the discontinued operations as held for sale in the consolidated balance sheets.

NOTE 18 — COMMITMENTS AND CONTINGENCIES

Legal and environmental

Department of Environmental Conservation of New York State (“DEC”), with ISC Properties, Inc. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted operations at a location in Peekskill in the Town of Cortlandt, New York (the “Peekskill Site”) owned by ISC Properties, Inc. (“ISC”), a wholly-owned subsidiary of Griffon. ISC sold the Peekskill Site in November 1982.

Subsequently, ISC was advised by the DEC that random sampling at the Peekskill Site and in a creek near the Peekskill Site indicated concentrations of solvents and other chemicals common to Lightron’s prior plating operations. ISC then entered into a consent order with the DEC in 1996 (the “Consent Order”) to perform a remedial investigation and prepare a feasibility study. After completing the initial remedial investigation pursuant to the Consent Order, ISC was required by the DEC, and did accordingly conduct over the next several years, supplemental remedial investigations, including soil vapor investigations, under the Consent Order.

In April 2009, the DEC advised ISC’s representatives that both the DEC and the New York State Department of Health had reviewed and accepted an August 2007 Remedial Investigation Report and an Additional Data Collection Summary Report dated January 30, 2009. With the acceptance of these reports, ISC completed the remedial investigation required under the Consent Order and was authorized, accordingly, by the DEC to conduct the Feasibility Study required by the Consent Order. Pursuant to the requirements of the Consent Order and its obligations thereunder, ISC, without acknowledging any responsibility to perform any

24

remediation at the Site, submitted to the DEC in August 2009, a draft feasibility study which recommended for the soil, groundwater and sediment media, remediation alternatives having a current net capital cost value, in the aggregate, of approximately $5,000 . In February 2011, DEC advised ISC it has accepted and approved the feasibility study. Accordingly, ISC has no further obligations under the consent order.

Upon acceptance of the feasibility study, DEC issued a Proposed Remedial Action Plan (“PRAP”) that sets forth the proposed remedy for the site. The PRAP accepted the recommendation contained in the feasibility study for remediation of the soil and groundwater media, but selected a different remediation alternative for the sediment medium. The approximate cost and the current net capital cost value of the remedy proposed by DEC in the PRAP is $10,000 . After receiving public comments on the PRAP, the DEC issued a Record of Decision (“ROD”) that set forth the specific remedies selected and responded to public comments. The remedies selected by the DEC in the ROD are the same remedies as those set forth in the PRAP.

It is now expected that DEC will enter into negotiations with potentially responsible parties to request they undertake performance of the remedies selected in the ROD, and if such parties do not agree to implement such remedies, then the State of New York may use State Superfund money to remediate the Peekskill site and seek recovery of costs from such parties. Griffon does not acknowledge any responsibility to perform any remediation at the Peekskill Site.

Improper Advertisement Claim involving Union Tools ® Products. Beginning in December 2004, a customer of AMES had been named in various litigation matters relating to certain Union Tools products. The plaintiffs in those litigation matters asserted causes of action against the customer of AMES for improper advertisement to end consumers. The allegations suggested that advertisements led the consumers to believe that Union Tools’ hand tools were wholly manufactured within boundaries of the United States. The complaints asserted various causes of action against the customer of AMES under federal and state law, including common law fraud. At some point, the customer may seek indemnity (including recovery of its legal fees and costs) against AMES for an unspecified amount. Presently, AMES cannot estimate the amount of loss, if any, if the customer were to seek legal recourse against AMES.

Union Fork and Hoe, Frankfort, NY site. The former Union Fork and Hoe property in Frankfort, NY was acquired by Ames in 2006 as part of a larger acquisition, and has historic site contamination involving chlorinated solvents, petroleum hydrocarbons and metals. AMES has entered into an Order on Consent with the New York State Department of Environmental Conservation. While the Order is without admission or finding of liability or acknowledgment that there has been a release of hazardous substances at the site, AMES is required to perform a remedial investigation of certain portions of the property and to recommend a remediation option. At the conclusion of the remediation phase to the satisfaction of the DEC, the DEC will issue a Certificate of Completion. AMES has performed significant investigative and remedial activities in the last few years under work plans approved by the DEC, and the DEC has approved the final remedial investigation report. AMES submitted a Feasibility Study, evaluating a number of remedial options, and recommending excavation and offsite disposal of lead contaminated soils, capping of other areas of the site impacted by other metals and performing limited groundwater monitoring. The Company is now awaiting a DEC decision on the Feasibility Study and the issuance of a Record of Decision. Implementation of the selected remedial alternative is expected to occur following regulatory approval. AMES has a number of defenses to liability in this matter, including its rights under a previous Consent Judgment entered into between the DEC and a predecessor of AMES relating to the site.

US Government investigations and claims

In general, departments and agencies of the US Government have the authority to investigate various transactions and operations of Griffon, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory or treble damages. US Government regulations provide that certain findings against a contractor may lead to suspension or debarment from future US Government contracts or the loss of export privileges for a company or an operating division or subdivision. Suspension or debarment could have a material adverse effect on Telephonics because of its reliance on government contracts.

25

General legal

Griffon is subject to various laws and regulations relating to the protection of the environment and is a party to legal proceedings arising in the ordinary course of business. Management believes, based on facts presently known to it, that the resolution of the matters above and such other matters will not have a material adverse effect on Griffon’s consolidated financial position, results of operations or cash flows.

NOTE 19 — CONSOLIDATING GUARANTOR AND NON-GUARANTOR FINANCIAL INFORMATION

Griffon’s Senior Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by the domestic assets of Clopay Building Products Company, Inc., Clopay Plastic Products Company, Inc. ("PPC"), Telephonics Corporation, The AMES Companies, Inc., ATT Southern, Inc., Clopay Ames True Temper Holding Corp., and ClosetMaid, LLC, all of which are indirectly 100% owned by Griffon. In accordance with Rule 3-10 of Regulation S-X promulgated under the Securities Act of 1933, presented below are condensed consolidating financial information as of December 31, 2017 and September 30, 2017 and for the three months ended December 31, 2017 and 2016 .

The guarantor companies and the non-guarantor companies include the consolidated financial results of their wholly-owned subsidiaries accounted for under the equity method.

The indenture relating to the Senior Notes (the “Indenture”) contains terms providing that, under certain limited circumstances, a guarantor will be released from its obligations to guarantee the Senior Notes. These circumstances include (i) a sale of at least a majority of the stock, or all or substantially all the assets, of the subsidiary guarantor as permitted by the Indenture; (ii) a public equity offering of a subsidiary guarantor that qualifies as a “Minority Business” as defined in the Indenture (generally, a business the EBITDA of which constitutes less than 50% of the segment adjusted EBITDA of the Company for the most recently ended four fiscal quarters), and that meets certain other specified conditions as set forth in the Indenture; (iii) the designation of a guarantor as an “unrestricted subsidiary” as defined in the Indenture, in compliance with the terms of the Indenture; (iv) Griffon exercising its right to defease the Senior Notes, or to otherwise discharge its obligations under the Indenture, in each case in accordance with the terms of the Indenture; and (v) upon obtaining the requisite consent of the holders of the Senior Notes. Accordingly, at the time of closing of the sale of PPC, the guarantee given by PPC relating to the Senior Notes will be released.

Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations

BUSINESS OVERVIEW

Griffon Corporation (the “Company” or “Griffon”) is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital.

Headquartered in New York, N.Y., the Company was founded in 1959 and is incorporated in Delaware. Griffon is listed on the New York Stock Exchange and trades under the symbol GFF.

On September 5, 2017, Griffon announced it would explore strategic alternatives for Clopay Plastic Products Company, Inc. ("PPC") and on November 16, 2017, announced it entered into a definitive agreement to sell PPC to Berry Global Group, Inc. (NYSE:BERY) ("Berry") for $475 million in cash. The transaction is subject to regulatory approval and customary closing conditions, and is expected to close in the first quarter of calendar 2018. As a result, Griffon classified the results of operations of the PPC business as discontinued operations in the Consolidated Statements of Operations for all periods presented and classified the related assets and liabilities associated with the discontinued operations as held for sale in the consolidated balance sheets. All results and information presented exclude PPC unless otherwise noted. PPC is a global leader in the development and production of embossed, laminated and printed specialty plastic films for hygienic, health-care and industrial products and sells to some of the world's largest consumer products companies. See Note 14, Discontinued Operations.

On October 2, 2017, Griffon acquired ClosetMaid LLC ("ClosetMaid"). ClosetMaid, founded in 1965, is a leading North American manufacturer and marketer of closet organization, home storage, and garage storage products, and sells to some of the largest home center retail chains, mass merchandisers, and direct-to-builder professional installers in North America. The accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations of ClosetMaid are included in the Company’s consolidated financial statements from the date of acquisition of October 2, 2017. See Note 3, Acquisitions.

Griffon currently conducts its operations through two reportable segments:

• Home & Building Products (“HBP”) consists of three companies, The AMES Companies, Inc. (“AMES”), Clopay Building Products Company, Inc. (“CBP”) and ClosetMaid:

  • AMES, founded in 1774, is the leading US manufacturer and a global provider of long-handled tools and landscaping products for homeowners and professionals.

  • CBP, since 1964, is a leading manufacturer and marketer of residential and commercial garage doors and sells to professional dealers and some of the largest home center retail chains in North America.

  • ClosetMaid, founded in 1965, is a leading North American manufacturer and marketer of closet organization, home storage, and garage storage products, and sells to some of the largest home center retail chains, mass merchandisers, and direct-to-builder professional installers.

• Telephonics Corporation ("Telephonics"), founded in 1933, is recognized globally as a leading provider of highly sophisticated intelligence, surveillance and communications solutions for defense, aerospace and commercial customers.

We are focused on acquiring, owning and operating businesses in a variety of industries. We are long-term investors that have substantial experience in a variety of industries. Our intent is to continue the growth of our existing segments and diversify further through investments and acquisitions.

As a result of the decline in the U.S. housing market, in May 2008, we announced the divestiture of our Installation Services business, which was consummated by September 2008. In September 2008, Griffon strengthened its balance sheet by raising $248,600 in equity through a common stock rights offering and a related investment by GS Direct L.L.C., an affiliate of The Goldman Sachs Group, Inc. Since that time, Griffon has continued to refine and enhance the strategic direction and operating

performance of its companies, while strengthening its balance sheet. During this period, Griffon has grown revenue and earnings through organic growth, cost containment and acquisitions, while returning capital to its shareholders through dividends and stock buybacks.

From October 2008 through May 10, 2017, Griffon's Employee Stock Ownership Plan ("ESOP") purchased 4,562,371 shares of Griffon's common stock, for a total of $54,186 or $11.88 per share. During the year ended September 30, 2017, Griffon's ESOP purchased 621,875 shares of common stock for a total of $10,908 or $17.54 per share. As of December 31, 2017 , the ESOP holds 5,784,229 allocated and unallocated shares, or 12% of Griffon's outstanding shares, with a related loan balance of $41,827 , net of issuance costs.

On September 30, 2010, Griffon purchased AMES for $542,000. Subsequently, Griffon acquired seven businesses complementary to AMES: the pots and planters business of Southern Sales & Marketing ("Southern Patio"), Northcote Pottery ("Northcote"), the Australian Garden and Tools division of Illinois Tool Works, Inc. ("Cyclone"), Hills Home Living ("Hills"), La Hacienda Limited ("La Hacienda"), Tuscan Landscape Group Ltd ("Tuscan Path") and Harper Brush Works (“Harper”).

On October 17, 2011, AMES acquired Southern Patio for approximately $23,000. Southern Patio, is a leading designer, manufacturer and marketer of landscape accessories.

In January 2013, AMES announced its intention to close certain U.S. manufacturing facilities and consolidate affected operations primarily into its Camp Hill and Carlisle, PA locations. These actions, which were completed at the end of the first quarter of 2015, improved manufacturing and distribution efficiencies, allowed for in-sourcing of certain production previously performed by third party suppliers, and improved material flow and absorption of fixed costs. Savings began in the second quarter of 2015 and have exceeded $10,000 on an annual basis.

On December 31, 2013, AMES acquired Northcote, founded in 1897 and a leading brand in the Australian outdoor planter and decor market, for approximately $22,000.

On May 21, 2014, AMES acquired Cyclone for approximately $40,000. Cyclone offers a full range of quality garden and hand tool products sold under various leading brand names including Cyclone®, Nylex® and Trojan®, designed to meet the requirements of both the Do-it-Yourself and professional trade segments. The Northcote and Cyclone acquisitions complement Southern Patio and add to AMES' existing lawn and garden operations in Australia.

On December 30, 2016, AMES Australia acquired Hills for approximately $6,051 (AUD 8,400). Hills, founded in 1946, is a market leader in the supply of clothesline, laundry and garden products. The Hills acquisition adds to AMES' existing broad category of products and enhances its lawn and garden product offerings in Australia.

On July 31, 2017 AMES acquired La Hacienda, a leading United Kingdom outdoor living brand of unique heating and garden decor products, for approximately $11,400 (GBP 9,175). The acquisition of La Hacienda broadens AMES' global outdoor living and lawn and garden business and supports AMES' UK expansion strategy. La Hacienda is expected to generate approximately GBP 14,000 of revenue in the first twelve months after the acquisition.

On September 29, 2017, AMES Australia acquired Tuscan Path for approximately $18,000 (AUD 22,250). Tuscan Path is a leading Australian provider of pots, planters, pavers, decorative stone, and garden decor products. The acquisition of Tuscan Path broadens AMES' outdoor living and lawn and garden business, and will strengthen AMES' industry leading position in Australia. Tuscan Path is expected to generate approximately AUD 25,000 in revenue in the first twelve months after the acquisition.

On November 6, 2017, AMES acquired Harper, a division of Horizon Global, for approximately $5,000. Harper is a leading U.S. manufacturer of cleaning products for professional, home, and industrial use. The acquisition will broaden AMES’ long-handled tool offering in North America to include brooms, brushes, and other cleaning tools and accessories. The acquisition is expected to contribute approximately $10,000 in revenue in the first twelve months after the acquisition.

From August 2011 through December 31, 2017 , Griffon repurchased 20,429,298 shares of its common stock, for a total of $261,621 or $12.81 per share. This included the repurchase of 15,984,854 shares on the open market, as well as the December 10, 2013 repurchase of 4,444,444 shares from GS Direct for $50,000 , or $11.25 per share.

Under these programs, the Company may purchase shares in the open market, including pursuant to a 10b5-1 plan, or in privately negotiated transactions. At December 31, 2017 , $49,437 remains under the August 3, 2016 Board authorization.

On October 2, 2017, Griffon completed the acquisition of ClosetMaid, a market leader of home storage and organization products, for approximately $185,700, inclusive of post-closing adjustments, or $165,000 net of the estimated present value of tax benefits under the current tax law. ClosetMaid adds to Griffon's Home and Building Products segment, complementing and diversifying Griffon's portfolio of leading consumer brands and products. ClosetMaid is expected to generate approximately $300,000 in revenue in the first twelve months after the acquisition.

OVERVIEW

Revenue for the quarter ended December 31, 2017 was $437,303 compared to $352,277 in the prior year quarter, an increase of 24%, primarily driven by increased revenue at Home & Building Products from both recent acquisitions and organic growth, partially offset by decreased revenue at Telephonics. Income from continuing operations was $22,831 or $0.53 per share, compared to $7,044 or $0.17 per share, in the prior year quarter. The current quarter results from continuing operations included the following:

– Acquisition costs of $3,185 ( $2,348 , net of tax, or $0.05 per share);

– Cost of life insurance benefit of $2,614 ( $248 , net tax, or $0.01 ); and

– Discrete and certain other tax benefits, net, of $(23,018) or $(0.53) per share.

The prior year quarter included net tax benefits of $4,421 or $0.10 per share, primarily related to discrete benefits for the adoption of recent Financial Accounting Standards Board guidance, which requires the Company to recognize excess tax benefits from the vesting of equity awards within income tax expense.

Excluding these items from the respective quarterly results, Income from continuing operations would have been $2,409 or $0.06 per share in the current quarter compared to $2,623 or $0.06 per share in the prior year quarter.

Griffon evaluates performance based on Income from Continuing operations and the related Earnings per share excluding restructuring charges, loss on debt extinguishment, acquisition related expenses and discrete and certain other tax items, as well as other items that may affect comparability, as applicable. Griffon believes this information is useful to investors for the same reason.

Revenue $ 66,325 $ 88,093
Segment operating profit $ 1,480 2.2 % $ 5,391 6.1%
Depreciation and amortization 2,719 2,717
Segment adjusted EBITDA $ 4,199 6.3 % $ 8,108 9.2%

For the quarter ended December 31, 2017 , revenue decreased $21,768 or 25% compared to the prior year quarter, primarily due to decreased maritime surveillance radar and airborne intercommunications systems revenue.

For the quarter ended December 31, 2017 , Segment operating profit decreased $3,911 or 73% compared to the prior year quarter, primarily driven by reduced margin on decreased revenue noted above.

During the three months ended December 31, 2017 , Telephonics was awarded several new contracts and received incremental funding on existing contracts approximating $47,500. Contract backlog was $332,000 at December 31, 2017 , with 70% expected to be fulfilled in the next 12 months. Backlog was $350,900 at September 30, 2017. Backlog is defined as unfilled firm orders for products and services for which funding has been both authorized and appropriated by the customer or Congress, in the case of US government agencies. The decrease in backlog was primarily due to the timing of various US and international contract awards associated with radar and surveillance opportunities.

Unallocated

For the quarter ended December 31, 2017 , unallocated amounts totaled $10,436 compared to $10,311 in the prior year. The increase in the current quarter compared to the respective prior year period primarily relates to compensation and incentive expenses.

Segment Depreciation and Amortization

Segment depreciation and amortization increased $968 for the quarter ended December 31, 2017 compared to the comparable prior year period, primarily due to depreciation and amortization on acquired assets acquired in acquisitions.

Other Income (Expense)

For the quarters ended December 31, 2017 and 2016 , Other income (expense) included $(437) and ($132) , respectively, of net currency exchange losses in connection with the translation of receivables and payables denominated in currencies other than the functional currencies of Griffon and its subsidiaries as well as $(5) and $87 , respectively, of net investment income (loss).

Provision for income taxes

On December 22, 2017, the “Tax Cuts and Jobs Act” ("TCJA") was signed into law, significantly impacting several sections of the Internal Revenue Code. ASC 740, Accounting for Income Taxes , requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions, January 1, 2018. Though certain key aspects of the TCJA are effective January 1, 2018 and have an immediate accounting effect, other significant provisions are not effective or may not result in accounting effects for September 30 fiscal year companies until October 1, 2018.

Given the significance of the TCJA, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period”. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared or analyzed.

Among the significant changes to the U.S. Internal Revenue Code, the TCJA lowers the U.S. federal corporate income tax rate (“Federal Tax Rate”) from 35% to 21% effective January 1, 2018. The Company will compute its income tax expense for the September 30, 2018 fiscal year using a blended Federal Tax Rate of 24.5%. The 21% Federal Tax Rate will apply to fiscal years ending September 30, 2019 and each year thereafter.

Table of Contents

The Company has recorded provisional amounts for the effects of the TCJA where accounting is not complete but a reasonable estimate has been determined. The company recorded a $23,941 benefit on the revaluation of deferred tax liabilities as a provisional amount for the re-measurement of deferred tax assets and liabilities, as well as an amount for deductible executive compensation expense, both of which have been reflected in the tax benefit for the quarter ended December 31, 2017.

A reasonable estimate cannot yet be made and therefore taxes are reflected based on the law in effect prior to the enactment of the TCJA for the impact of the one-time mandatory repatriation transition tax on the net accumulated earnings and profits of a U.S. taxpayer’s foreign subsidiaries, bonus depreciation expensing for qualified property placed in service after September 27, 2017 and the impact on state income taxes.

The provisional amounts incorporate assumptions made based upon the Company’s current interpretation of the TCJA and may change as the Company receives additional clarification and implementation guidance.

In accordance with SAB 118 adjustments recorded to the provisional amounts will be reflected within the measurement period through the quarter ended December 31, 2018 and will be included in income from continuing operations and net income as an adjustment to tax expense.

In the quarter ended December 31, 2017, the Company recognized a tax benefit of $24,904 on a Loss before taxes from continuing operations of $2,073 , compared to a tax benefit of $2,613 on Income before taxes from continuing operations of $4,431 in the comparable prior year quarter.

The quarters ended December 31, 2017 and 2016 tax rates included net tax benefits that affect comparability of $23,018 and $4,421 , respectively. The current year quarter ended December 31, 2017 included discrete tax benefits from the December 22, 2017 tax reform bill primarily from approximately $23,941 related to revaluation of deferred tax liabilities. The prior year quarter ended December 31, 2016 included discrete benefits from the adoption of Financial Accounting Standards Board guidance which requires the Company to recognize excess tax benefits from the vesting of equity awards within income tax expense. Excluding these tax items, the effective tax rates for the quarters ended December 31, 2017 and 2016 were 35.4% and 40.8% , respectively.

Stock based compensation

For the quarters ended December 31, 2017 and 2016 , stock based compensation expense totaled $2,555 and $2,452 , respectively.

Comprehensive income (loss)

For the quarter ended December 31, 2017 , total other comprehensive income, net of taxes, of $8,358 , included a $1,289 loss from foreign currency translation adjustments primarily due to the weakening of the Australian and Canadian currencies, offset by the strengthening of the Euro currency, all in comparison to the US Dollar, a $9,559 benefit from pension amortization of actuarial losses and a $88 gain on cash flow hedges.

For the quarter ended December 31, 2016, total other comprehensive loss, net of taxes, of $11,312, included a $13,479 loss from foreign currency translation adjustments primarily due to the weakening of the Euro, Canadian and Australian currencies, all in comparison to the US Dollar, a $544 benefit from pension amortization of actuarial losses and a $1,623 gain on cash flow hedges.

Discontinued operations

Plastic Products Company

On September 5, 2017, Griffon announced it would explore strategic alternatives for Clopay Plastic Products Company, Inc. ("PPC") and on November 16, 2017, announced it entered into a definitive agreement to sell PPC to Berry for $475 million in cash. As a result, the following PPC results have been classified PPC as a discontinued operation.

For the Three Months Ended December 31, — 2017 2016
Revenue $ 120,430 $ 114,823
Segment operating profit $ 12,448 10.3 % $ 8,031 7.0 %
Depreciation and amortization 6,406
Segment adjusted EBITDA $ 12,448 10.3 % $ 14,437 12.6 %

For the quarter ended December 31, 2017 , revenue increased $5,607 or 5% compared to the prior year quarter driven by increased volume in North America, favorable product mix in Europe and favorable resin pricing of $1,500, or 1%, partially offset by reduced volume in Europe and unfavorable mix in North America. PPC adjusts selling prices based on underlying resin costs on a delayed basis.

For the quarter ended December 31, 2017 , Segment operating profit increased $4,417 or 55% compared to the prior year quarter. Depreciation and amortization was excluded from the current year results since PPC is classified as a discontinued operations and accordingly, the Company ceased depreciation and amortization in accordance with discontinued operations accounting guidelines. Depreciation and amortization would have been approximately $7,400 in the quarter ended December 31, 2017. Including depreciation and amortization in the current year results, Segment operating profit would have been approximately $5,048, a decrease of $2,983 or 37%, driven by unfavorable product mix. Resin pricing did not have a material impact on EBITDA for the quarter.

Installation Services and Other Discontinued Activities

In 2008, as a result of the downturn in the residential housing market, Griffon exited substantially all operating activities of its Installation Services segment which sold, installed and serviced garage doors and openers, fireplaces, floor coverings, cabinetry and a range of related building products, primarily for the new residential housing market. Griffon sold eleven units, closed one unit and merged two units into CBP. Operating results of substantially this entire segment have been reported as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income (Loss) for all periods presented; Installation Services is excluded from segment reporting.

Griffon substantially concluded remaining disposal activities in 2009. There was no revenue or income from the Installation Services’ business for the quarters ended December 31, 2017 and 2016 .

During the year ended September 30, 2017, Griffon recorded $5,700 of reserves in discontinued operations related to historical environmental remediation efforts and to increase the reserve for homeowner association claims (HOA) related to installation services.

At December 31, 2017, Griffon’s assets and liabilities for discontinued operations primarily related to income taxes and product liability, warranty and environmental reserves. Future net cash outflows to satisfy liabilities related to disposal activities accrued as of December 31, 2017 are estimated to be $5,679 .

LIQUIDITY AND CAPITAL RESOURCES

Management assesses Griffon’s liquidity in terms of its ability to generate cash to fund its operating, investing and financing activities. Significant factors affecting liquidity are: cash flows from operating activities, capital expenditures, acquisitions, dispositions, bank lines of credit and the ability to attract long-term capital under satisfactory terms. Griffon believes it has sufficient liquidity available to invest in its existing businesses and execute strategic acquisitions, while managing its capital structure on both a short-term and long-term basis.

The following table is derived from the Condensed Consolidated Statements of Cash Flows:

On October 2, 2017, in an unregistered offering through a private placement under Rule 144A, Griffon completed the add-on offering of $275,000 principal amount of its 5.25% senior notes due 2022, at 101.00% of par, to Griffon's previously issued $125,000 principal amount of its 5.25% senior notes due 2022, at 98.76% of par, completed on May 18, 2016 and $600,000 5.25% senior notes due 2022, at par, completed on February 27, 2014 (collectively the “Senior Notes”). As of December 31, 2017 , outstanding Senior Notes due totaled $1,000,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the $275,000 add-on offering were used, among other things, to acquire ClosetMaid with the remaining proceeds used to pay down outstanding loan borrowings under Griffon's Credit Agreement. The net proceeds of the previously issued $125,000 add-on offering were used to pay down outstanding revolving loan borrowings under Griffon's Credit Agreement.

The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On December 18, 2017, July 20, 2016 and June 18, 2014, Griffon exchanged all of the $275,000 , $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of the Senior Notes approximated $1,020,000 on December 31, 2017 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $275,000 senior notes, Griffon capitalized $8,434 of underwriting fees and other expenses; Griffon capitalized $3,016 of underwriting fees and other expenses in connection with the $125,000 senior notes; and Griffon capitalized $10,313 in connection with the previously issued $600,000 senior notes. All capitalized fees will amortize over the term of the notes.

On March 22, 2016, Griffon amended the Credit Agreement to increase the credit facility from $250,000 to $350,000 , extend its maturity from March 13, 2020 to March 22, 2021, and modify certain other provisions of the facility. On October 2, 2017, Griffon further amended the Credit Agreement in association with the ClosetMaid Acquisition to modify the net leverage covenant through the quarter ended March 31, 2019. The facility includes a letter of credit sub-facility with a limit of $50,000 and a multi-currency sub-facility of $50,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.25% for base rate loans and 2.25% for LIBOR loans. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon's material domestic subsidiaries securing a limited amount of the debt under the Credit Agreement relating to Griffon's Employee Stock Ownership Plan ("ESOP") ranks pari passu with the lien granted on such assets under the Credit Agreement). At December 31, 2017 , there were $147,743 in outstanding borrowings and standby letters of credit were $14,938 under the Credit Agreement; $187,319 was available, subject to certain loan covenants, for borrowing at that date.

As of December 31, 2017 , $41,827 , net of issuance costs, was outstanding under the Term Loan.

The leases both mature in 2022 , and bear interest at a fixed rates of approximately 5.0% and 8.0%, respectively.

In July 2016, Griffon Australia Holdings Pty Ltd and its Australian subsidiaries ("Griffon Australia") entered into an AUD 30,000 term loan and an AUD 10,000 revolver. The term loan refinanced two existing term loans and the revolver replaced two existing lines. In December 2016, the amount available under the revolver was increased from AUD 10,000 to AUD 20,000 and, in March 2017, the term loan commitment was increased by AUD 5,000 to AUD 33,500 . In September 2017, the term commitment was increased by AUD 15,000 to AUD 46,750. The term loan requires quarterly principal payments of AUD 1,250 plus interest, with a balloon payment of AUD 37,125 due upon maturity in June 2019, and accrues interest at Bank Bill Swap Bid Rate “BBSY” plus 2.00% per annum ( 3.84% at December 31, 2017 ).

Other long-term debt consists primarily of a loan with the Pennsylvania Industrial Development Authority, with the balance consisting of capital leases.

On August 3, 2016, Griffon’s Board of Directors authorized the repurchase of up to $50,000 of Griffon’s outstanding common stock. Under this share repurchase program, the Company may, from time to time, purchase shares of its common stock in the open market, including pursuant to a 10b5-1 plan, or in privately negotiated transactions. There were no repurchases under these programs during the quarter ended December 31, 2017. From August 2011 through December 31, 2017 , Griffon repurchased 20,429,298 shares of its common stock, for a total of $261,621 or $12.81 per share.

GS Direct continues to hold approximately 5.6 million shares of Griffon’s common stock.

Subject to certain exceptions, if GS Direct intends to sell its remaining shares of Griffon common stock at any time prior to December 31, 2018, it will first negotiate in good faith to sell such shares to the Company.

In addition, during the quarter ended December 31, 2017 , 191,332 shares, with a market value of $4,332 , or $22.64 per share, were withheld to settle employee taxes due upon the vesting of restricted stock, and were added to treasury stock.

During the quarter ended December 31, 2017, the Board of Directors approved a quarterly cash dividend of $0.07 per share. The Company currently intends to pay dividends each quarter; however, payment of dividends is determined by the Board of Directors at its discretion based on various factors, and no assurance can be provided as to the payment of future dividends.

On January 30, 2018, the Board of Directors declared a quarterly cash dividend of $0.07 per share, payable on March 22, 2018 to shareholders of record as of the close of business on February 22, 2018.

CRITICAL ACCOUNTING POLICIES

The preparation of Griffon’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the use of estimates, assumptions, judgments and subjective interpretations of accounting principles that have an impact on assets, liabilities, revenue and expenses. These estimates can also affect supplemental information contained in public disclosures of Griffon, including information regarding contingencies, risk and its financial condition. These estimates, assumptions and judgments are evaluated on an ongoing basis and based on historical experience, current conditions and various other assumptions, and form the basis for estimating the carrying values of assets and liabilities, as well as identifying and assessing the accounting treatment for commitments and contingencies. Actual results may materially differ from these estimates. There have been no changes in Griffon’s critical accounting policies from September 30, 2017 .

Griffon’s significant accounting policies and procedures are explained in the Management Discussion and Analysis section in the Annual Report on Form 10-K for the year ended September 30, 2017 . In the selection of the critical accounting policies, the objective is to properly reflect the financial position and results of operations for each reporting period in a consistent manner that can be understood by the reader of the financial statements. Griffon considers an estimate to be critical if it is subjective and if changes in the estimate using different assumptions would result in a material impact on the financial position or results of operations of Griffon.

RECENT ACCOUNTING PRONOUNCEMENTS

The FASB issues, from time to time, new financial accounting standards, staff positions and emerging issues task force consensus. See the Notes to Condensed Consolidated Financial Statements for a discussion of these matters.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, especially “Management’s Discussion and Analysis”, contains certain “forward-looking statements” within the meaning of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Such statements relate to, among other things, income (loss), earnings, cash flows, revenue, changes in operations, operating improvements, industries in which Griffon Corporation (the “Company” or “Griffon”) operates and the United States and global economies. Statements in this Form 10-Q that are not historical are hereby identified as “forward-looking statements” and may be indicated by words or phrases such as “anticipates,” “supports,” “plans,” “projects,” “expects,” “believes,” “should,” “would,” “could,” “hope,” “forecast,” “management is of the opinion,” “may,” “will,” “estimates,” “intends,” “explores,” “opportunities,” the negative of these expressions, use of the future tense and similar words or phrases. Such forward-looking statements are subject to inherent risks and uncertainties that could cause actual results to differ materially from those expressed in any forward-looking statements. These risks and uncertainties include, among others: current economic conditions and uncertainties in the housing, credit and capital markets; Griffon’s ability to achieve expected savings from cost control, restructuring, integration and disposal initiatives; the ability to identify and successfully consummate and integrate value-adding acquisition opportunities; increasing competition and pricing pressures in the markets served by Griffon’s operating companies; the ability of Griffon’s operating companies to expand into new geographic and product markets and to anticipate and meet customer demands for new products and product enhancements and innovations; reduced military spending

by the government on projects for which Griffon’s Telephonics Corporation supplies products, including as a result of defense budget cuts or other government actions; the ability of the federal government to fund and conduct its operations; increases in the cost of raw materials such as resin, wood and steel; changes in customer demand or loss of a material customer at one of Griffon’s operating companies; the potential impact of seasonal variations and uncertain weather patterns on certain of Griffon’s businesses; political events that could impact the worldwide economy; a downgrade in Griffon’s credit ratings; changes in international economic conditions including interest rate and currency exchange fluctuations; the reliance by certain of Griffon’s businesses on particular third party suppliers and manufacturers to meet customer demands; the relative mix of products and services offered by Griffon’s businesses, which impacts margins and operating efficiencies; short-term capacity constraints or prolonged excess capacity; unforeseen developments in contingencies, such as litigation, regulatory and environmental matters; unfavorable results of government agency contract audits of Telephonics Corporation; Griffon’s ability to adequately protect and maintain the validity of patent and other intellectual property rights; the cyclical nature of the businesses of certain of Griffon’s operating companies; and possible terrorist threats and actions and their impact on the global economy. Additional important factors that could cause the statements made in this Quarterly Report on Form 10-Q or the actual results of operations or financial condition of Griffon to differ are discussed under the caption “Item 1A. Risk Factors” and “Special Notes Regarding Forward-Looking Statements” in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2017 . Readers are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements speak only as of the date made. Griffon undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Item 3 - Quantitative and Qualitative Disclosure About Market Risk

Griffon’s business’ activities necessitates the management of various financial and market risks, including those related to changes in interest rates, foreign currency rates and commodity prices.

Interest Rates

Griffon’s exposure to market risk for changes in interest rates relates primarily to variable interest rate debt and investments in cash and equivalents.

The Credit Agreement and certain other of Griffon’s credit facilities have a LIBOR-based variable interest rate. Due to the current and expected level of borrowings under these facilities, a 100 basis point change in LIBOR would not have a material impact on Griffon’s results of operations or liquidity.

Foreign Exchange

Griffon conducts business in various non-US countries, primarily in Canada, Australia, Mexico and China; therefore, changes in the value of the currencies of these countries affect Griffon's financial position and cash flows when translated into US Dollars. Griffon has generally accepted the exposure to exchange rate movements relative to its non-US operations. Griffon may, from time to time, hedge its currency risk exposures. A change of 10% or less in the value of all applicable foreign currencies would not have a material effect on Griffon’s financial position and cash flows.

Item 4 - Controls and Procedures

Under the supervision and with the participation of Griffon’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), were evaluated as of the end of the period covered by this report. Based on that evaluation, Griffon’s CEO and CFO concluded that Griffon’s disclosure controls and procedures were effective at the reasonable assurance level.

During the period covered by this report, there were no changes in Griffon’s internal control over financial reporting which materially affected, or are reasonably likely to materially affect, Griffon’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

Griffon believes that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all controls issues and instances of fraud, if any, within a company have been detected. Griffon’s disclosure controls and procedures, as defined by Exchange Act Rule 13a-15(e) and 15d-15(e), are designed to provide reasonable assurance of achieving their objectives.

Amendment No. 1 to the Griffon Corporation 2016 Equity Incentive Plan

On January 31, 2018, Griffon’s stockholders approved Amendment No. 1 to the Griffon Corporation Equity Incentive Plan (the "Incentive Plan") at the 2018 annual meeting of stockholders (the “Annual Meeting”), pursuant to which 1,000,000 shares were added to the Incentive Plan and which provided that any dividend or other distribution payable with respect to a restricted share award (or with respect to any other award), will be paid if, and only at such time as, the restricted share award (or other award) vests.

This summary description of Amendment No. 1 to the Incentive Plan is qualified in its entirety by reference to (i) the description of the Incentive Plan and Amendment No. 1 to the Incentive Plan included in Griffon’s Proxy Statement relating to its Annual Meeting filed with the Securities and Exchange Commission on December 18, 2017 (the “Proxy Statement”), and (ii) the actual Incentive Plan and Amendment No. 1 to the Incentive Plan, a copy of each which were included as Annexes A and B to the Proxy Statement, respectively, and are incorporated herein by reference.

Submission of Matters to a Vote of Security Holders.

On January 31, 2018, Griffon held its Annual Meeting. Of the 47,310,984 shares of common stock outstanding and entitled to vote, 45,393,721 shares, or 96%, were represented at the meeting in person or by proxy, and therefore a quorum was present. The final results for each of the matters submitted to a vote of stockholders at the Annual Meeting are as follows:

45,003,081 244,632 146,008

*As previously disclosed, Harvey R. Blau, who was up for re-election as a Class II director, passed away prior to the Annual Meeting. In accordance with the Proxy Statement, the Board, upon the recommendation of the Nominating and Corporate Governance Committee, designated Mr. Henry A. Alpert as the substitute nominee for the Class II directorship for which Mr. Blau was nominated. As a result, any shares voted by proxy FOR the election of Mr. Blau as a Class II director at the Annual Meeting were instead voted for the election of Mr. Alpert as a Class II director. Because Mr. Alpert was elected as a Class II director at the Annual Meeting, concurrently with such election, he ceased to serve as a Class III director. The Board intends to appoint a successor director to fill the resulting Class III director vacancy in due course in accordance with the terms of the Company’s certificate of incorporation and by-laws.

48

Mr. Blau was also the Company’s Chairman of the Board. The Board has appointed Ronald J. Kramer, the Company’s Chief Executive Officer, to succeed Mr. Blau as Chairman of the Board.
