NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Basis of Presentation

The consolidated financial statements of Apogee Enterprises, Inc. (we, us, our or the Company) have been prepared in accordance with accounting principles generally accepted in the United States. The information included in this Form 10-Q should be read in conjunction with the Company’s Form 10-K for the year ended March 4, 2017. We use the same accounting policies in preparing quarterly and annual financial statements. All adjustments necessary for a fair presentation of quarterly operating results are reflected herein and are of a normal, recurring nature. The results of operations for the nine-month period ended December 2, 2017 are not necessarily indicative of the results to be expected for the full year.

Subsequent events

In connection with preparing the unaudited consolidated financial statements for the nine months ended December 2, 2017, we evaluated subsequent events for potential recognition and disclosure through the date of this filing. On December 20, 2017, the Tax Cuts and Jobs Act (the "2017 Act") was signed into law. We are in the process of preparing and analyzing information to determine the impact of the 2017 Act on our accounting for income taxes, including the remeasurement of our deferred tax assets and liabilities. The consolidated financial statements presented herein do not reflect any impact that may result from completing the accounting for the income tax effects of the 2017 Act.

Subsequent to the end of the quarter, in late December 2017 and early January 2018, we purchased 246,299 shares of stock under our authorized share repurchase program, at a total cost of $11.1 million.

On January 5, 2018, we announced a restructuring plan that involves the closure of our St. George, UT architectural glass manufacturing facility in March 2018, enabled by our investments in productivity and increased capabilities, which have led to an increase in capacity. This and other restructuring activities are expected to have an approximately $4.5 million pre-tax impact in our fiscal fourth quarter.

2. New Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2017, our fiscal 2019. We have undertaken a comprehensive assessment process at each of our businesses and have concluded on the application of the new guidance at nearly all of our businesses. We are in the process of quantifying the impact that this standard will have on our financial statements upon adoption. At this time:

• We plan to adopt the guidance following a modified retrospective transition method, with a cumulative effect adjustment to opening retained earnings in fiscal 2019. We are in the process of determining this retained earnings adjustment.

• We have determined that some of our business units will continue to recognize revenue at the point in time when goods are shipped, as that represents when control is transferred to the customer. We also have business units that continue to recognize revenue over time, following a cost-to-cost percentage of completion method of revenue recognition.

• We expect that two of our business units will change from recognizing revenue at a point in time to recognizing revenue over time, to better reflect transfer of control to the customer in line with the new guidance. We are continuing to assess the appropriate measure of progress toward completion, based on the facts and circumstances specific to the performance obligations and terms of sale of each business.

• We are in the process of evaluating how the revenue recognition guidance applies to EFCO, the business acquired in the second quarter of fiscal 2018.

In February 2016, the FASB issued ASU 2016-02, Leases, which provides for comprehensive changes to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, our fiscal year 2020, with a modified retrospective transition. The adoption of this standard will result in reflecting assets and liabilities for the value of our leased property and equipment on our consolidated balance sheet, but we do not currently expect this guidance to have a significant impact on our consolidated results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, and in November 2016, it issued 2016-18, Restricted Cash. Both standards provide guidance for presentation of certain topics within the statement of cash flows, including presenting

9

restricted cash within cash and cash equivalents, and are intended to improve consistency in presentation. The new classification guidance is effective for fiscal years beginning after December 15, 2017, our fiscal year 2019, and is to be applied retrospectively for comparability across all periods. We do not expect this guidance to have a significant impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairment by requiring impairment charges to be based on the first step in the current two-step impairment test process. The new guidance eliminates the current requirement to calculate a goodwill impairment charge using step 2. The standard is applicable to impairment tests performed in periods beginning after December 15, 2019, our fiscal 2021, with early adoption permitted. We are currently evaluating early adoption of this guidance for our future annual goodwill impairment review process.

3. Share-Based Compensation

Total share-based compensation expense included in the results of operations was $4.6 million for the nine-month period ended December 2, 2017 and $4.4 million for the nine-month period ended November 26, 2016.

Stock Options and SARs

Stock option and SAR activity for the current nine-month period is summarized as follows:

Stock Options and SARs	Number of Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value
Outstanding at March 4, 2017	229,901		$	9.90
Awards exercised	(100,000	)	8.34
Outstanding and exercisable at December 2, 2017	129,901		$	11.10	3.0 Years	$	4,878,738

Cash proceeds from the exercise of stock options were $0.8 million and $1.3 million for the nine months ended December 2, 2017 and November 26, 2016, respectively. The aggregate intrinsic value of securities exercised (the amount by which the stock price on the date of exercise exceeded the stock price of the award on the date of grant) was $4.8 million during the nine months ended December 2, 2017 and $4.5 million during the prior-year period.

Nonvested Shares and Share Units

Nonvested share activity for the current nine-month period is summarized as follows:

Nonvested Shares and Units	Number of Shares and Units		Weighted Average Grant Date Fair Value
Nonvested at March 4, 2017	279,204		$	44.79
Granted	124,416		55.40
Vested	(130,093	)	45.31
Canceled	(7,000	)	55.89
Nonvested at December 2, 2017	266,527		$	49.20

At December 2, 2017, there was $8.5 million of total unrecognized compensation cost related to nonvested share and nonvested share unit awards, which is expected to be recognized over a weighted average period of approximately 21 months. The total fair value of shares vested during the nine months ended December 2, 2017 was $7.0 million.

4. Earnings per Share

The following table presents a reconciliation of the share amounts used in the computation of basic and diluted earnings per share:

	Three Months Ended		Nine Months Ended
(In thousands)	December 2, 2017	November 26, 2016	December 2, 2017	November 26, 2016
Basic earnings per share – weighted average common shares outstanding	28,736	28,828	28,812	28,807
Weighted average effect of nonvested share grants and assumed exercise of stock options	82	64	50	109
Diluted earnings per share – weighted average common shares and potential common shares outstanding	28,818	28,892	28,862	28,916

10

There were no anti-dilutive stock options excluded from the calculation of earnings per share for any of the periods presented, as the average market price exceeded the exercise price of options outstanding.

5. Inventories

(In thousands)	December 2, 2017		March 4, 2017
Raw materials	$	35,565	$	22,761
Work-in-process	24,919		16,154
Finished goods	34,951		29,372
Costs and earnings in excess of billings on uncompleted contracts	2,627		5,122
Total inventories	$	98,062	$	73,409

6. Marketable Securities

Marketable securities are classified as available for sale:

(In thousands)	Amortized Cost	Gross Unrealized Gains	Gross Unrealized Losses		Estimated Fair Value
December 2, 2017
Municipal bonds	10,334	17	(103	)	10,248
March 4, 2017
Municipal bonds	9,595	91	(97	)	9,589

We have a wholly-owned insurance subsidiary, Prism Assurance, Ltd. (Prism), which holds municipal bonds. Prism insures a portion of our general liability, workers’ compensation and automobile liability risks using reinsurance agreements to meet statutory requirements. The reinsurance carrier requires Prism to maintain fixed-maturity investments, which are generally high-quality municipal bonds, for the purpose of providing collateral for Prism’s obligations under the reinsurance agreements.

The amortized cost and estimated fair values of municipal bonds at December 2, 2017, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities, as borrowers may have the right to call or prepay obligations with or without penalty.

(In thousands)	Amortized Cost		Estimated Fair Value
Due within one year	$	482	$	482
Due after one year through five years	4,418		4,385
Due after five years through 10 years	4,627		4,578
Due after 10 years through 15 years	141		141
Due beyond 15 years	666		662
Total	$	10,334	$	10,248

7. Fair Value Measurements

Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data). We do not have any Level 3 financial assets or liabilities.

Cash equivalents

Fair value of money market funds was determined based on quoted prices for identical assets in active markets. Commercial paper was measured at fair value using inputs based on quoted prices for similar securities in active markets.

Short- and long-term securities

Municipal bonds were measured at fair value based on market prices from recent trades of similar securities and are classified as short-term or long-term based on maturity date.

8. Acquisitions

EFCO

In line with our strategic objectives, on June 12, 2017, we acquired 100 percent of the stock of EFCO Corporation, a privately held U.S. manufacturer of architectural aluminum window, curtainwall, storefront and entrance systems for commercial construction projects, for $192 million in cash. The acquisition was funded through our committed revolving credit facility, with $7.5 million of the purchase price payable in equal installments over the next three years. EFCO's results of operations have been included in our consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Those results include $135.3 million of sales and $6.1 million of operating income since the date of acquisition.

The assets and liabilities of EFCO were recorded in our consolidated balance sheet as of the acquisition date, at their respective fair values. Fair value is estimated based on one or a combination of income, cost and/or market approaches, as determined based on the nature of the asset or liability, and the level of inputs available. With respect to assets and liabilities, the determination of fair value requires management to make subjective judgments as to projections of future operating performance, the appropriate discount rate to apply, long-term growth rates, etc. (i.e. - unobservable inputs classified as Level 3 inputs under the fair value hierarchy described in Note 7), which affect the amounts recorded in the purchase price allocation. The excess of the consideration transferred over the fair value of the identifiable assets, net of liabilities, is recorded as goodwill, which is indicative of the expected continued growth and development of EFCO. The purchase price allocation is based on these estimated fair values of assets acquired and liabilities assumed, as follows:

12

(In thousands)
Net working capital	$	34,156
Property, plant and equipment	43,815
Goodwill	57,460
Other intangible assets	71,500
Less: Long-term liabilities acquired, net	14,605
Net assets acquired	$	192,326

Other intangible assets reflect the following:

Customer relationships	$	34,800	16
Tradename	32,400		Indefinite
Backlog	4,300		1.5
	$	71,500

These fair values are based on preliminary estimates and are subject to change based on finalization of net working capital items included in the purchase price allocation.

Sotawall

On December 14, 2016, we acquired substantially all the assets of Sotawall, Inc., now operating under the name Sotawall Limited ("Sotawall"). Sotawall specializes in the design, engineering, fabrication, assembly and installation of unitized curtainwall systems for industrial, commercial and institutional buildings, primarily serving the Canadian and northeastern U.S. geographic regions. Sotawall's results of operations have been included in our consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Purchase accounting related to the acquisition of Sotawall was finalized during the the first quarter of fiscal 2018.

The following table sets forth certain unaudited pro forma consolidated data for the combined company for the third quarters and first nine-month periods of fiscal 2018 and 2017, as if the EFCO and Sotawall acquisitions were consummated pursuant to each of their respective same terms at the beginning of the fiscal year preceding their respective acquisition dates.

10. Debt

We maintain a committed revolving credit facility with maximum borrowings of up to $335.0 million, maturing in November 2021. Outstanding borrowings under our committed revolving credit facility were $209.0 million, as of December 2, 2017, and $45.0 million, as of March 4, 2017. Under this facility, we are subject to two financial covenants that require us to stay below a

14

maximum debt-to-EBITDA ratio and maintain a minimum ratio of interest expense-to-EBITDA. Both ratios are computed quarterly, with EBITDA calculated on a rolling four-quarter basis. At December 2, 2017, we were in compliance with both financial covenants. Additionally, at December 2, 2017, we had a total of $26.3 million of ongoing letters of credit related to industrial revenue bonds and construction contracts that expire in fiscal 2018 and reduce availability of funds under our committed credit facility.

At December 2, 2017, our debt also included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043 and $0.4 million of long-term debt in Canada. The fair value of the industrial revenue bonds approximated carrying value at December 2, 2017, due to the variable interest rates on these instruments. All debt would be classified as Level 2 within the fair value hierarchy described in Note 7.

We also maintain two Canadian revolving demand credit facilities totaling $12.0 million Canadian dollars. As of December 2, 2017, $1.5 million was outstanding under these facilities, and no borrowings were outstanding as of March 4, 2017. Borrowings under these facilities are made available at the sole discretion of the lenders and are payable on demand. The Company classifies any outstanding balances under this demand facility as long-term debt, as outstanding amounts can be refinanced through our committed revolving credit facility.

Interest payments were $3.6 million and $0.5 million for the nine months ended December 2, 2017 and November 26, 2016, respectively.

11. Employee Benefit Plans

The Company sponsors two frozen defined-benefit pension plans: an unfunded Officers’ Supplemental Executive Retirement Plan and the Tubelite Inc. Hourly Employees’ Pension Plan. Components of net periodic benefit cost were:

Net periodic benefit cost	$	180		$	185		$	540		$	555

12. Income Taxes

The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2015, or U.S. state and local income tax examinations for years prior to fiscal 2011. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2014, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions.

The total liability for unrecognized tax benefits at December 2, 2017 and March 4, 2017 was approximately $5.4 million and $4.5 million, respectively. Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. The total liability for unrecognized tax benefits is expected to decrease by approximately $0.3 million during the next 12 months due to lapsing of statutes.

14.Commitments and Contingent Liabilities

Operating lease commitments. As of December 2, 2017, the Company was obligated under non-cancelable operating leases for buildings and equipment. Certain leases provide for increased rental payments based upon increases in real estate taxes or operating costs. Future minimum rental payments under non-cancelable operating leases are:

(In thousands)	Remainder of Fiscal 2018		Fiscal 2019		Fiscal 2020		Fiscal 2021		Fiscal 2022		Thereafter		Total
Total minimum payments	$	3,615	$	13,546	$	11,493	$	8,477	$	7,626	$	21,232	$	65,989

Bond commitments. In the ordinary course of business, predominantly in our Architectural Services and Architectural Framing Systems segments, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At December 2, 2017, $86.4 million of our backlog was bonded by performance bonds with a face value of $310.0 million. Performance bonds do not have stated expiration dates, as we are generally released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our current portfolio of businesses.

Warranties. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims, for product warranty and rework cost, based on historical product liability claims as a ratio of sales. Claim costs are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, changes in product mix and any significant changes in sales volume. A warranty rollforward follows:

Acquired reserves	5,571			—
Balance at end of period	$	22,693		$	17,544

Letters of credit. At December 2, 2017, we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The total value of letters of credit under which we were obligated as of December 2, 2017 was approximately $26.3 million, all of which have been issued under our committed revolving credit facility. Availability under this credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility.

Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $120.9 million as of December 2, 2017.

Litigation. We are a party to various legal proceedings incidental to our normal operating activities. In particular, like others in the construction supply and services industry, our businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. We are also subject to litigation arising out of general liability, employment practices, workers' compensation and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on our results of operations, cash flows or financial condition.

The following selected financial data should be read in conjunction with the Company’s Form 10-K for the year ended March 4, 2017 and the consolidated financial statements, including the notes to consolidated financial statements, included therein.

Highlights of Third Quarter and First Nine Months of Fiscal 2018 Compared to Third Quarter and First Nine Months of Fiscal 2017

Net sales

Consolidated net sales increased 30.1 percent, or $82.4 million, for the third quarter ended December 2, 2017, and 21.5 percent, or $172.3 million, for the nine-month period ended December 2, 2017, compared to the same periods in the prior year. Sales growth was primarily due to the addition of EFCO in June 2017 and Sotawall in December 2016 within the Architectural Framing Systems segment, partially offset by the decline in our Architectural Services segment. Foreign currency did not have a meaningful impact on sales results in the current-year period or the prior-year period.

The relationship between various components of operations, as a percentage of net sales, is illustrated below:

	Three Months Ended				Nine Months Ended
(Percent of net sales)	December 2, 2017		November 26, 2016		December 2, 2017		November 26, 2016
Net sales	100.0	%	100.0	%	100.0	%	100.0	%

Gross profit	25.7		26.6		25.5		26.2
Selling, general and administrative expenses	16.0		14.5		16.6		14.7
Operating income	9.7		12.1		8.9		11.5
Interest and other (expense) income, net	(0.3	)	—		(0.3	)	—
Earnings before income taxes	9.4		12.1		8.6		11.5
Income tax expense	2.7		3.9		2.7		3.8
Net earnings	6.6	%	8.2	%	5.9	%	7.7	%
Effective tax rate	29.1	%	32.1	%	31.7	%	32.8	%

Gross profit

Gross profit as a percent of sales was 25.7 percent and 25.5 percent for the three- and nine-month periods, respectively, ended December 2, 2017, compared to 26.6 percent and 26.2 percent for the three- and nine-month periods ended November 26, 2016. Gross profit as a percent of sales declined from the prior-year periods primarily due to the inclusion of the lower gross margin EFCO business in the three-month period ended December 2, 2017, and reduced volume leverage in the Architectural Services segment in both the three- and nine-month periods ended December 2, 2017.

Selling, general and administrative (SG&A) expenses

SG&A expenses as a percent of sales were 16.0 percent and 16.6 percent in the three- and nine-month periods ended December 2, 2017, compared to 14.5 percent of sales and 14.7 percent of sales in the three- and nine-month periods, respectively, last year. The increases in the current year periods were primarily due to amortization of the intangible assets acquired in the Sotawall and EFCO transactions and EFCO acquisition-related costs. These two factors combined made up approximately 170 basis points of the increase in each of the three- and nine-month periods of fiscal 2018, compared to the prior-year periods.

Income tax expense

The effective tax rate in the third quarter of fiscal 2018 was 29.1 percent, compared to 32.1 percent in the same period last year, and 31.7 percent for the first nine months of fiscal 2018, compared to 32.8 percent in the prior-year period. The decline in both periods was due mainly to a tax benefit on the recognition of a foreign currency loss.

Segment Analysis

Architectural Framing Systems

	Three Months Ended								Nine Months Ended
(In thousands)	December 2, 2017			November 26, 2016			% Change		December 2, 2017		November 26, 2016		% Change
Net sales	$	194,157		$	90,850		113.7	%	493,672		264,212		86.8	%
Operating income	18,452			11,838			55.9	%	46,958		35,070		33.9	%
Operating margin	9.5		%	13.0		%			9.5	%	13.3	%

Architectural Framing Systems net sales increased $103.3 million, or 113.7 percent, and $229.5 million, or 86.8 percent, for the three- and nine-month periods, respectively, ended December 2, 2017, over the same periods in the prior year. The addition of the net sales of EFCO and Sotawall provided over 80 percent of the growth in both periods. The remaining growth was from share gains and geographic growth in North America within our legacy businesses.

Operating margin declined 350 basis points and 380 basis points for the three- and nine-month periods, respectively, of the current year, compared to the same periods in the prior year. The decline in the three-month period resulted from 280 basis points of amortization of acquired intangible assets and, for the nine-month period, the amortization of acquired intangible assets resulted in 240 basis points of the decline. Additionally, operating margin in both periods was impacted by the inclusion of EFCO at lower operating margins.

Backlog in this segment, as of December 2, 2017, was approximately $449 million, compared to approximately $245 million at fiscal year-end, with the addition of EFCO contributing over 90 percent of the increase.

Architectural Glass

	Three Months Ended								Nine Months Ended
(In thousands)	December 2, 2017			November 26, 2016			% Change		December 2, 2017			November 26, 2016			% Change

Operating income	9,107			11,708			(22.2	)%	28,687			30,855			(7.0	)%
Operating margin	9.4		%	10.9		%			9.8		%	10.3		%

Net sales declined $10.1 million, or 9.4 percent, for the quarter-ended December 2, 2017, over the same period in the prior year, due to delays in the timing of certain larger projects in the United States, partially as a result of hurricane-related project delays in Florida. Sales for the nine-month period ended December 2, 2017 decreased $7.5 million, or 2.5 percent, over the prior-year period due to delays in timing of larger projects, partly offset by share gains in mid-size projects. Foreign currency impact on sales was nominal in the current-year periods compared to the respective prior-year periods.

Operating margin declined 150 basis points and 50 basis points for the three- and nine-month periods, respectively, of the current year, compared to the same periods in the prior year. The declines in both periods were driven by reduced operating leverage on lower volume, and pricing and mix declines. These negative factors were partially offset by improved manufacturing productivity.

Given the short lead times in this segment, we do not consider backlog to be a significant metric.

Architectural Services

	Three Months Ended								Nine Months Ended

Operating margin	5.2		%	7.6		%			2.8		%	7.0		%

Architectural Services net sales decreased $15.3 million, or 23.8 percent, and $58.9 million, or 28.7 percent, for the three- and nine-month periods, respectively, ended December 2, 2017, over the same periods in the prior year, primarily due to year-on-year timing of project activity.

19

Operating margin declined 240 basis points and 420 basis points for the three- and nine-month periods, respectively, of the current year, over the same periods in the prior year, due to lower volume leverage on fixed project management, engineering and manufacturing costs.

As of December 2, 2017, backlog in this segment grew to approximately $346 million, compared to approximately $255 million at fiscal year-end.

Operating margin	25.9		%	26.8		%			23.1		%	24.6		%

LSO net sales increased $3.9 million, or 17.7 percent, and $1.5 million, or 2.4 percent, for the three- and nine-month periods ended December 2, 2017, respectively, over the comparable prior-year periods, as a result of strong customer orders, partly due to timing, and success in new display markets.

Operating margin declined 90 basis points and 150 basis points for the three- and nine-month periods of the current year, respectively, over the same periods in the prior year, due to accrual of additional incentive compensation on stronger current-year performance. In the current quarter, this was partially offset by improved operating leverage on increased volume.

Given the short lead times in this segment, we do not consider backlog to be a significant metric.

Operating Activities. Cash provided by operating activities was $66.2 million for the first nine months of fiscal 2018, decreasing $6.6 million compared to the prior-year period, as a result of increased working capital investment due to reduced accrued expenses.

Investing Activities. Net cash used in investing activities was $215.6 million the first nine months of fiscal 2018, primarily due to the cash paid for the acquisition of EFCO, while in the first nine months of the prior year, net cash used by investing activities of $59.2 million was driven by capital expenditures. Additionally, in fiscal 2018, we released the remaining $7.8 million of cash that was restricted for investment in our oversized glass fabrication project within our Architectural Glass segment. We estimate fiscal 2018 capital expenditures to be $55 to $60 million, as we continue to invest in productivity and capabilities.

We continually review our portfolio of businesses and their assets in comparison to our internal strategic and performance objectives. As part of this review, we may acquire other businesses, pursue geographic expansion, take actions to manage capacity and/or further invest in, fully divest and/or sell parts of our current businesses. As a result, on January 5, 2018 we announced a plan to close the St. George, UT architectural glass manufacturing facility in March 2018, enabled by our investments in productivity and increased capabilities, which have led to an increase in capacity.

20

Financing Activities. At December 2, 2017, we had outstanding borrowings under our credit facility of $209.0 million. As defined within our amended committed revolving credit facility, we are required to comply with two financial covenants. These financial covenants require us to stay below a maximum leverage ratio and to maintain a minimum interest coverage ratio. At December 2, 2017, we were in compliance with both financial covenants.

We paid dividends totaling $12.0 million ($0.42 per share) in the first nine months of fiscal 2018. As of December 2, 2017, we repurchased 200,000 shares under our authorized share repurchase program, for a total cost of $10.8 million; all such repurchases were made in the second quarter. In fiscal 2017, we repurchased 250,001 shares under this program, for a total cost of $10.8 million; all such repurchases were made in the third quarter. Subsequent to the end of the quarter, we purchased 246,299 shares under the program, at a total cost of $11.1 million. Including these shares, we have purchased a total of 3,753,932 shares, at a cost of $94.2 million, since the fiscal 2004 inception of this program. In January 2018, our repurchase authority under this program increased by 1,000,000 shares. As a result of both of these actions, we have remaining authority to repurchase 1,496,068 shares.

Other Financing Activities. The following summarizes our significant contractual obligations that impact our liquidity as of December 2, 2017:

	Payments Due by Fiscal Period
(In thousands)	Remainder of Fiscal 2018		Fiscal 2019		Fiscal 2020		Fiscal 2021		Fiscal 2022		Thereafter		Total
Long-term debt obligations	$	597	$	1,583	$	108	$	5,508	$	211,108	$	13,022	$	231,926
Operating leases (undiscounted)	3,615		13,546		11,493		8,477		7,626		21,232		65,989
Purchase obligations	48,572		67,615		2,247		1,230		1,230		—		120,894
Total cash obligations	$	52,784	$	82,744	$	13,848	$	15,215	$	219,964	$	34,254	$	418,809

The long-term debt obligations due in fiscal 2022 relate primarily to borrowings under our committed revolving credit facility. From time to time, we acquire the use of certain assets through operating leases, such as warehouses, vehicles, forklifts, office equipment, hardware, software and some manufacturing equipment. Many of these operating leases have termination penalties. However, because the assets are used in the conduct of our business operations, it is unlikely that any significant portion of these operating leases would be terminated prior to the normal expiration of their lease terms. Therefore, we consider the risk related to termination penalties to be minimal.

Purchase obligations in the table above relate to raw material commitments and capital expenditures.

We expect to make contributions of $1.0 million to our defined-benefit pension plans in fiscal 2018, which will equal or exceed our minimum funding requirements.

As of December 2, 2017, we had reserves of $5.4 million and $1.4 million for unrecognized tax benefits and environmental liabilities, respectively. We currently expect approximately $0.3 million of the unrecognized tax benefits to lapse during the next 12 months. We are unable to reasonably estimate in which future periods the remaining unrecognized tax benefits and environmental liabilities will ultimately be settled. We are currently in the process of evaluating information to determine the impact the recently enacted Tax Cuts and Jobs Act will have on our accounting for income taxes.

At December 2, 2017, we had a total of $26.3 million of ongoing letters of credit related to industrial revenue bonds and construction contracts that expire in fiscal 2018 and reduce availability of funds under our committed credit facility.

In addition to the above standby letters of credit, we are required, in the ordinary course of business, to provide surety or performance bonds that commit payments to our customers for any non-performance by us. At December 2, 2017, $86.4 million of our backlog was bonded by performance bonds with a face value of $310.0 million. Performance bonds do not have stated expiration dates, as we are generally released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our current portfolio of businesses.

Due to our ability to generate strong cash from operations and borrowing capability under our committed revolving credit facility, we believe that our sources of liquidity will continue to be adequate to fund our working capital requirements, planned capital expenditures and dividend payments for at least the next 12 months.

Non-GAAP Measures

We analyze non-GAAP measures for adjusted net earnings, adjusted earnings per diluted common share and adjusted operating income. These measures are used by management to evaluate the Company's financial performance on a more consistent basis and improve comparability of results from period to period, because they exclude certain amounts that management does not consider to be part of the Company's core operating results. Examples of items excluded to arrive at these adjusted measures may include the impact of acquisition-related costs, amortization of short-lived acquired intangibles associated with backlog and non-recurring restructuring costs. These non-GAAP measures should be viewed in addition to, and not as an alternative to, the reported financial results of the company prepared in accordance with GAAP. The non-GAAP measures presented below may differ from similar measures used by other companies.

The following table reconciles net earnings to adjusted net earnings and earnings per diluted common share to adjusted earnings per diluted common share.

Outlook

The following statements are based on our current expectations for full-year fiscal 2018 results, not including any estimated impact from the 2017 Tax Cuts and Jobs Act. These statements are forward-looking, and actual results may differ materially. We are currently expecting:

• Revenue growth of approximately 20 percent over fiscal 2017.

• Operating margin of 8.6 percent to 8.9 percent.

• Earnings per diluted share of $2.58 to $2.68.

• Adjusted operating margin of 10.1 to 10.4 percentand adjusted earnings per diluted share of $3.04 to $3.14⁽¹⁾.

• Capital expenditures of $55 to $60 million.

⁽¹⁾Adjusted operating margin and adjusted earnings per diluted share exclude the impact of amortization of short-lived acquired intangible assets associated with the acquired backlog of Sotawall and EFCO of $7 million (after tax, $0.24 per diluted share) and acquisition-related costs for EFCO of approximately $3.1 million (after tax, $0.11 per diluted share). These two adjustments have a combined approximate 100 basis point negative impact on operating margin. Adjusted operating margin and adjusted earnings per diluted share also exclude the impact of planned fourth-quarter restructuring charges of approximately $4.5 million (after tax, $0.11 per diluted share). These non-GAAP measures are used by management to evaluate the Company's historical and prospective financial performance, measure operational profitability on a more consistent basis, and provide enhanced transparency to the investment community. These non-GAAP measures should be viewed in addition to, and not as an alternative to, the financial results of the company prepared in accordance with GAAP.

Related Party Transactions

No material changes have occurred in the disclosure with respect to our related party transactions set forth in our Annual Report on Form 10-K for the fiscal year ended March 4, 2017.

Critical Accounting Policies

No material changes have occurred in the disclosure of our critical accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended March 4, 2017.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

No material changes have occurred to the disclosures of quantitative and qualitative market risk set forth in our Annual Report on Form 10-K for the fiscal year ended March 4, 2017.

Item 4. Controls and Procedures

a) Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this report (the Evaluation Date), we carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in applicable rules and forms, and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

b) Changes in internal controls: There was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended December 2, 2017, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company has been a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company’s construction supply and services businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is also subject to litigation arising out of employment practices, workers compensation, general liability and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.

Item 1A. Risk Factors

There have been no material changes or additions to our risk factors discussed in our Annual Report on Form 10-K for the fiscal year ended March 4, 2017.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The consolidated financial statements of Apogee Enterprises, Inc. (we, us, our or the Company) have been prepared in accordance with accounting principles generally accepted in the United States. The information included in this Form 10-Q should be read in conjunction with the Company’s Form 10-K for the year ended March 4, 2017. We use the same accounting policies in preparing quarterly and annual financial statements. All adjustments necessary for a fair presentation of quarterly operating results are reflected herein and are of a normal, recurring nature. The results of operations for the nine-month period ended December 2, 2017 are not necessarily indicative of the results to be expected for the full year.

Subsequent events

In connection with preparing the unaudited consolidated financial statements for the nine months ended December 2, 2017, we evaluated subsequent events for potential recognition and disclosure through the date of this filing. On December 20, 2017, the Tax Cuts and Jobs Act (the "2017 Act") was signed into law. We are in the process of preparing and analyzing information to determine the impact of the 2017 Act on our accounting for income taxes, including the remeasurement of our deferred tax assets and liabilities. The consolidated financial statements presented herein do not reflect any impact that may result from completing the accounting for the income tax effects of the 2017 Act.

Subsequent to the end of the quarter, in late December 2017 and early January 2018, we purchased 246,299 shares of stock under our authorized share repurchase program, at a total cost of $11.1 million.

On January 5, 2018, we announced a restructuring plan that involves the closure of our St. George, UT architectural glass manufacturing facility in March 2018, enabled by our investments in productivity and increased capabilities, which have led to an increase in capacity. This and other restructuring activities are expected to have an approximately $4.5 million pre-tax impact in our fiscal fourth quarter.

Accounting Changes and Error Corrections [Abstract]

New Accounting Standards

New Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Under the new standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2017, our fiscal 2019. We have undertaken a comprehensive assessment process at each of our businesses and have concluded on the application of the new guidance at nearly all of our businesses. We are in the process of quantifying the impact that this standard will have on our financial statements upon adoption. At this time:

• We plan to adopt the guidance following a modified retrospective transition method, with a cumulative effect adjustment to opening retained earnings in fiscal 2019. We are in the process of determining this retained earnings adjustment.

• We have determined that some of our business units will continue to recognize revenue at the point in time when goods are shipped, as that represents when control is transferred to the customer. We also have business units that continue to recognize revenue over time, following a cost-to-cost percentage of completion method of revenue recognition.

• We expect that two of our business units will change from recognizing revenue at a point in time to recognizing revenue over time, to better reflect transfer of control to the customer in line with the new guidance. We are continuing to assess the appropriate measure of progress toward completion, based on the facts and circumstances specific to the performance obligations and terms of sale of each business.

• We are in the process of evaluating how the revenue recognition guidance applies to EFCO, the business acquired in the second quarter of fiscal 2018.

In February 2016, the FASB issued ASU 2016-02, Leases, which provides for comprehensive changes to lease accounting. The new standard requires that a lessee recognize a lease obligation liability and a right to use asset for virtually all leases of property, plant and equipment, subsequently amortized over the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, our fiscal year 2020, with a modified retrospective transition. The adoption of this standard will result in reflecting assets and liabilities for the value of our leased property and equipment on our consolidated balance sheet, but we do not currently expect this guidance to have a significant impact on our consolidated results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, and in November 2016, it issued 2016-18, Restricted Cash. Both standards provide guidance for presentation of certain topics within the statement of cash flows, including presenting restricted cash within cash and cash equivalents, and are intended to improve consistency in presentation. The new classification guidance is effective for fiscal years beginning after December 15, 2017, our fiscal year 2019, and is to be applied retrospectively for comparability across all periods. We do not expect this guidance to have a significant impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairment by requiring impairment charges to be based on the first step in the current two-step impairment test process. The new guidance eliminates the current requirement to calculate a goodwill impairment charge using step 2. The standard is applicable to impairment tests performed in periods beginning after December 15, 2019, our fiscal 2021, with early adoption permitted. We are currently evaluating early adoption of this guidance for our future annual goodwill impairment review process.

Share-Based Compensation

Total share-based compensation expense included in the results of operations was $4.6 million for the nine-month period ended December 2, 2017 and $4.4 million for the nine-month period ended November 26, 2016.

Stock Options and SARs

Stock option and SAR activity for the current nine-month period is summarized as follows:

Outstanding and exercisable at December 2, 2017	129,901		$	11.10	3.0 Years	$	4,878,738

Cash proceeds from the exercise of stock options were $0.8 million and $1.3 million for the nine months ended December 2, 2017 and November 26, 2016, respectively. The aggregate intrinsic value of securities exercised (the amount by which the stock price on the date of exercise exceeded the stock price of the award on the date of grant) was $4.8 million during the nine months ended December 2, 2017 and $4.5 million during the prior-year period.

Nonvested Shares and Share Units

Nonvested share activity for the current nine-month period is summarized as follows:

Nonvested Shares and Units	Number of Shares and Units		Weighted Average Grant Date Fair Value
Nonvested at March 4, 2017	279,204		$	44.79
Granted	124,416		55.40

Canceled	(7,000	)	55.89
Nonvested at December 2, 2017	266,527		$	49.20

At December 2, 2017, there was $8.5 million of total unrecognized compensation cost related to nonvested share and nonvested share unit awards, which is expected to be recognized over a weighted average period of approximately 21 months. The total fair value of shares vested during the nine months ended December 2, 2017 was $7.0 million.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Financial assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1 (unadjusted quoted prices in active markets for identical assets or liabilities); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data). We do not have any Level 3 financial assets or liabilities.

Cash equivalents

Fair value of money market funds was determined based on quoted prices for identical assets in active markets. Commercial paper was measured at fair value using inputs based on quoted prices for similar securities in active markets.

Short- and long-term securities

Municipal bonds were measured at fair value based on market prices from recent trades of similar securities and are classified as short-term or long-term based on maturity date.

Acquisition

Acquisitions

EFCO

In line with our strategic objectives, on June 12, 2017, we acquired 100 percent of the stock of EFCO Corporation, a privately held U.S. manufacturer of architectural aluminum window, curtainwall, storefront and entrance systems for commercial construction projects, for $192 million in cash. The acquisition was funded through our committed revolving credit facility, with $7.5 million of the purchase price payable in equal installments over the next three years. EFCO's results of operations have been included in our consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Those results include $135.3 million of sales and $6.1 million of operating income since the date of acquisition.

The assets and liabilities of EFCO were recorded in our consolidated balance sheet as of the acquisition date, at their respective fair values. Fair value is estimated based on one or a combination of income, cost and/or market approaches, as determined based on the nature of the asset or liability, and the level of inputs available. With respect to assets and liabilities, the determination of fair value requires management to make subjective judgments as to projections of future operating performance, the appropriate discount rate to apply, long-term growth rates, etc. (i.e. - unobservable inputs classified as Level 3 inputs under the fair value hierarchy described in Note 7), which affect the amounts recorded in the purchase price allocation. The excess of the consideration transferred over the fair value of the identifiable assets, net of liabilities, is recorded as goodwill, which is indicative of the expected continued growth and development of EFCO. The purchase price allocation is based on these estimated fair values of assets acquired and liabilities assumed, as follows:

(In thousands)
Net working capital	$	34,156

Sotawall

On December 14, 2016, we acquired substantially all the assets of Sotawall, Inc., now operating under the name Sotawall Limited ("Sotawall"). Sotawall specializes in the design, engineering, fabrication, assembly and installation of unitized curtainwall systems for industrial, commercial and institutional buildings, primarily serving the Canadian and northeastern U.S. geographic regions. Sotawall's results of operations have been included in our consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Purchase accounting related to the acquisition of Sotawall was finalized during the the first quarter of fiscal 2018.

The following table sets forth certain unaudited pro forma consolidated data for the combined company for the third quarters and first nine-month periods of fiscal 2018 and 2017, as if the EFCO and Sotawall acquisitions were consummated pursuant to each of their respective same terms at the beginning of the fiscal year preceding their respective acquisition dates.

Debt

Debt

We maintain a committed revolving credit facility with maximum borrowings of up to $335.0 million, maturing in November 2021. Outstanding borrowings under our committed revolving credit facility were $209.0 million, as of December 2, 2017, and $45.0 million, as of March 4, 2017. Under this facility, we are subject to two financial covenants that require us to stay below a maximum debt-to-EBITDA ratio and maintain a minimum ratio of interest expense-to-EBITDA. Both ratios are computed quarterly, with EBITDA calculated on a rolling four-quarter basis. At December 2, 2017, we were in compliance with both financial covenants. Additionally, at December 2, 2017, we had a total of $26.3 million of ongoing letters of credit related to industrial revenue bonds and construction contracts that expire in fiscal 2018 and reduce availability of funds under our committed credit facility.

At December 2, 2017, our debt also included $20.4 million of industrial revenue bonds that mature in fiscal years 2021 through 2043 and $0.4 million of long-term debt in Canada. The fair value of the industrial revenue bonds approximated carrying value at December 2, 2017, due to the variable interest rates on these instruments. All debt would be classified as Level 2 within the fair value hierarchy described in Note 7.

We also maintain two Canadian revolving demand credit facilities totaling $12.0 million Canadian dollars. As of December 2, 2017, $1.5 million was outstanding under these facilities, and no borrowings were outstanding as of March 4, 2017. Borrowings under these facilities are made available at the sole discretion of the lenders and are payable on demand. The Company classifies any outstanding balances under this demand facility as long-term debt, as outstanding amounts can be refinanced through our committed revolving credit facility.

Interest payments were $3.6 million and $0.5 million for the nine months ended December 2, 2017 and November 26, 2016, respectively.

Income Taxes

The Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, Canada, Brazil and other international jurisdictions. The Company is no longer subject to U.S. federal tax examinations for years prior to fiscal 2015, or U.S. state and local income tax examinations for years prior to fiscal 2011. The Company is not currently under U.S. federal examination for years subsequent to fiscal year 2014, and there is very limited audit activity of the Company’s income tax returns in U.S. state jurisdictions or international jurisdictions.

The total liability for unrecognized tax benefits at December 2, 2017 and March 4, 2017 was approximately $5.4 million and $4.5 million, respectively. Penalties and interest related to unrecognized tax benefits are recorded in income tax expense. The total liability for unrecognized tax benefits is expected to decrease by approximately $0.3 million during the next 12 months due to lapsing of statutes.

Commitments and Contingent Liabilities

Operating lease commitments. As of December 2, 2017, the Company was obligated under non-cancelable operating leases for buildings and equipment. Certain leases provide for increased rental payments based upon increases in real estate taxes or operating costs. Future minimum rental payments under non-cancelable operating leases are:

Total minimum payments	$	3,615	$	13,546	$	11,493	$	8,477	$	7,626	$	21,232	$	65,989

Bond commitments. In the ordinary course of business, predominantly in our Architectural Services and Architectural Framing Systems segments, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At December 2, 2017, $86.4 million of our backlog was bonded by performance bonds with a face value of $310.0 million. Performance bonds do not have stated expiration dates, as we are generally released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our current portfolio of businesses.

Warranties. We reserve estimated exposures on known claims, as well as on a portion of anticipated claims, for product warranty and rework cost, based on historical product liability claims as a ratio of sales. Claim costs are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, changes in product mix and any significant changes in sales volume. A warranty rollforward follows:

Balance at end of period	$	22,693		$	17,544

Letters of credit. At December 2, 2017, we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The total value of letters of credit under which we were obligated as of December 2, 2017 was approximately $26.3 million, all of which have been issued under our committed revolving credit facility. Availability under this credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility.

Purchase obligations. Purchase obligations for raw material commitments and capital expenditures totaled $120.9 million as of December 2, 2017.

Litigation. We are a party to various legal proceedings incidental to our normal operating activities. In particular, like others in the construction supply and services industry, our businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. We are also subject to litigation arising out of general liability, employment practices, workers' compensation and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on our results of operations, cash flows or financial condition.
