Notes to Condensed Consolidated Financial Statements

Unaudited - Amounts in thousands except per share data and percentages

(1) Basis of Presentation

The Condensed Consolidated Financial Statements of A.M. Castle & Co. and its consolidated subsidiaries (collectively, the "Company") included herein and the notes thereto have been prepared by the Company, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), and accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet at December 31, 2019 is derived from the audited financial statements at that date. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. In the opinion of the Company's management, the unaudited statements included herein contain all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of financial results for the interim period. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The operating results for the three and nine months ended September 30, 2020, as reported herein, may not necessarily be indicative of the Company’s operating results for the full year.

(2) New Accounting Standards

Standards Updates Adopted

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU No. 2018-13 amends Fair Value Measurement (Topic 820) to add, remove, and modify fair value measurement disclosure requirements. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 820's disclosure requirements under the aforementioned FASB disclosure framework project. The Company adopted the disclosure requirements of ASU No. 2018-13 in the first quarter of 2020. The Company determined the adoption of the disclosure requirements had no impact on its fair value disclosures herein.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 amends ASC 740 to simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations and interim calculations, and adding guidance to reduce complexity in the accounting standard under the FASB’s simplification initiative. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020. Upon adoption, the amendments in ASU 2019-12 should be applied on a prospective basis to all periods presented. Early adoption is permitted. The Company adopted the new guidance under ASU 2019-12 in the first quarter of 2020 and removed the exception for intraperiod allocations from its interim period tax provision calculation, accordingly.

On March 2, 2020, the SEC issued Final Rule Release No. 33-10762, "Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities" (the “final rule”). The final rule simplifies the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rules 3-10 and 3-16, which currently require separate financial statements for (1) subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met and (2) affiliates that collateralize registered securities offerings if the affiliates’ securities are a substantial portion of the collateral. Under the final rule, alternative financial disclosures or narrative disclosures (referred to collectively as “Alternative Disclosures”) may be provided in lieu of separate financial statements of the guarantors or affiliates. The amendments in the final rule are generally effective for filings on or after January 4, 2021, with early application permitted. The Company has elected to adopt the amendments of the final rule for the quarter ended March 31, 2020 and accordingly, has elected to present the alternative disclosures of the guarantors of its registered securities in Part I Item 2, Management's Discussion and Analysis, of this Form 10-Q.

Standards Updates Issued Not Yet Effective

In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 adds a current expected credit loss (“CECL”) impairment model to U.S. GAAP that is based on expected losses rather than incurred losses. Modified retrospective adoption is required with any cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. ASU 2016-13 is effective for smaller

Table of Contents

reporting companies for fiscal years beginning after December 15, 2022, including interim periods within the year of adoption. Early adoption is permitted. The Company will adopt the guidance and disclosure requirements of ASU 2016-13 in fiscal year 2023.

In August 2018, the FASB issued ASU No. 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans - General (Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plan.” ASU No. 2018-14 amends Compensation - Retirement Benefits (Topic 715) to add or remove certain disclosure requirements related to defined benefit pension and other postretirement plans. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 715's disclosure requirements under the FASB’s disclosure framework project. ASU No. 2018-14 is effective for public entities for fiscal years beginning after December 15, 2020. ASU No. 2018-14 does not impact the interim disclosure requirements of Topic 715. Early adoption is permitted. The Company will adopt the disclosure requirements of this new guidance in fiscal year 2021.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The purpose of ASU 2020-04 is to provide optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting. In response to concerns about structural risks of interbank offered rates, and, in particular, the risk of cessation of the London Interbank Offered Rate (LIBOR), reference rate reform refers to a global initiative to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a topic or an industry subtopic, the amendments in ASU 2020-04 must be applied prospectively for all eligible contract modifications for that topic or industry subtopic. The Company is currently assessing the accounting and financial impact of reference rate reform and will consider applying the optional guidance of ASU 2020-04 accordingly.

(3) Revenue

The Company recognizes revenue from the sale of products when the earnings process is complete and when the title and risk and rewards of ownership have passed to the customer, which is primarily at the time of shipment. Revenue recognized other than at the time of shipment represented less than 1% of the Company’s consolidated net sales in the three and nine months ended September 30, 2020 and September 30, 2019, respectively. Customer payment terms are established prior to the time of shipment. Provisions for allowances related to sales discounts and rebates are recorded based on terms of the sale in the period that the sale is recorded. The Company utilizes historical information and the current sales trends of the Company's business to estimate such provisions. The provisions related to discounts and rebates due to customers are recorded as a reduction within net sales in the Company’s Condensed Consolidated Statements of Operations and Comprehensive Loss.

The Company records revenue from shipping and handling charges in net sales. Costs incurred in connection with shipping and handling the Company’s products, which are related to third-party carriers or performed by Company personnel, are included in warehouse, processing and delivery expenses. In the three months ended September 30, 2020 and September 30, 2019, shipping and handling costs included in warehouse, processing and delivery expenses were $4,559 and $5,869, respectively. In the nine months ended September 30, 2020 and September 30, 2019, shipping and handling costs included in warehouse, processing and delivery expenses were $15,007 and $18,165, respectively. As a practical expedient under Accounting Standards Codification No. 606, "Revenue from Contracts with Customers (Topic 606)" ("ASC 606"), the Company has elected to account for shipping and handling activities as fulfillment costs and not a promised good or service. As a result, there is no change to the Company's accounting for revenue from shipping and handling charges under ASC 606.

The Company maintains an allowance for doubtful accounts related to the potential inability of customers to make required payments. The allowance for doubtful accounts is maintained at a level considered appropriate based on historical experience and specific identification of customer receivable balances for which collection is unlikely. The provision for doubtful accounts is recorded in sales, general and administrative expense in the Company’s Condensed Consolidated Statements of Operations and Comprehensive Loss. Estimates of doubtful accounts are based on historical write-off experience as a percentage of net sales and judgments about the probable effects of economic conditions on certain customers. The Company increased its allowance for doubtful accounts during the three months ended September 30, 2020 primarily in response to certain customers that declared bankruptcy due to ongoing financial hardship. The Company continues to consider the economic impact of the novel coronavirus

Table of Contents

("COVID-19") pandemic as well as the currently unfavorable economic conditions on the collectability of customer accounts receivable. The Company continues to experience slowing in payments from customers due to the financial uncertainties resulting from the COVID-19 pandemic and will continue to analyze any financial and commercial impacts of the COVID-19 pandemic, including any adverse impact the COVID-19 pandemic may have on the collectability of customer accounts receivable.

The Company also maintains an allowance for credit memos for estimated credit memos to be issued against current sales. Estimates of allowance for credit memos are based upon the application of a historical issuance lag period to the average credit memos issued each month.

The Company does not incur significant incremental costs when obtaining customer contracts and any costs that are incurred are generally not recoverable from its customers. Substantially all of the Company's customer contracts are for a duration of less than one year and individual customer purchase orders for contractual customers are fulfilled within one year of the purchase order date. As a practical expedient under ASC 606, the Company has elected to continue to recognize incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. The Company does not have any costs to obtain a contract that are capitalized under ASC 606.

(4) Loss Per Share

Diluted loss per common share is computed by dividing net loss by the weighted average number of shares of the common stock of A.M. Castle & Co. outstanding plus outstanding common stock equivalents. Common stock equivalents consist of restricted stock awards and other share-based payment awards, and shares that may be issued upon conversion of the Company’s outstanding 5.00% / 7.00% Convertible Senior Secured Paid-in-Kind ("PIK") Toggle Notes due 2022 (the “5.00%/7.00% Convertible Notes”) and the Company's outstanding 3.00% / 5.00% Convertible Senior Secured PIK Toggle Notes due 2024 (the “3.00%/5.00% Convertible Notes”), which are included in the calculation of weighted average shares outstanding using the if-converted method. Refer to Note 6 - Debt, for further description of the 5.00%/7.00% Convertible Notes and the 3.00%/5.00% Convertible Notes.

The following table is a reconciliation of the basic and diluted loss per common share calculations:

Excluded outstanding share-based awards having an anti-dilutive effect	986		1,429		1,083		1,488

The computation of diluted loss per common share does not include common shares issuable upon conversion of the Company’s 5.00%/7.00% Convertible Notes or 3.00%/5.00% Convertible Notes, as they were anti-dilutive under the if-converted method.

The 5.00%/7.00% Convertible Notes are convertible into shares of the Company’s common stock at any time at the initial conversion price of $3.77 per share. The 3.00%/5.00% Convertible Notes are convertible into shares of the Company’s common stock at any time at the initial conversion price of $0.46 per share. In future periods, absent a fundamental change as described in Note 6 - Debt, the outstanding 5.00%/7.00% Convertible Notes and 3.00%/5.00% Convertible Notes could increase diluted average shares outstanding by a maximum of approximately 215,090 shares.

(5) Goodwill and Intangible Asset

As of December 31, 2019, the Company had goodwill with a carrying value of $2,676, none of which was tax deductible. As a result of the COVID-19 pandemic, which has spread across the globe to many countries in which the Company does business and is impacting worldwide economic activity, the Company has determined that the potential impact on its business, including, but not limited to, a potential decrease in revenue, supply chain disruptions and/or facility closures, represented facts and circumstances indicating that it was likely that its goodwill and indefinite lived trade name could be impaired, and performed interim impairment tests. Based on the results of the Company's interim goodwill impairment test performed in the third quarter of 2020, the Company determined its one reporting unit's goodwill was impaired. The Company recorded a non-cash goodwill impairment charge of $2,676 during the three months ended September 30, 2020, reducing the remaining balance of its goodwill to zero as of September 30, 2020.

The gross carrying value of the Company's trade name intangible asset, which is not subject to amortization, was $5,500 at both September 30, 2020 and December 31, 2019. Based on the results of the interim impairment tests of the indefinite-lived trade name assets performed in the first, second and third quarters of 2020, the Company determined its one reporting unit's indefinite-lived trade name asset was not impaired as of September 30, 2020.

While the Company considered the impact the COVID-19 pandemic may have on its future cash flows when preparing its interim goodwill and intangible asset impairment tests, the full extent of the impact that the COVID-19 pandemic will have on the Company's business, operations and financial condition is currently unknown. The Company will continue to assess its indefinite-lived trade name intangible asset for impairment as events and circumstances change.

Credit Facilities

On June 1, 2018, the Company entered into an Amendment No. 1 to Original ABL Credit Agreement (the “Credit Agreement Amendment No. 1”) by and among the Company, the Borrowers and guarantors party thereto and the Agent and the other lenders party thereto, which amended the Original ABL Credit Agreement to provide for additional borrowing capacity. On March 27, 2020, the Company entered into an Amendment No. 2 to the Original ABL Credit Agreement (the "Credit Agreement Amendment No. 2") by and among the Company, the Borrowers and guarantors party thereto and the Agent and the other lenders party thereto, which amended the Original ABL Credit Agreement (as amended by the Credit Agreement Amendment No. 1 and Credit Agreement No. 2, the “ABL Credit Agreement”) to permit the Exchange Offer (defined below) to proceed.

The ABL Credit Agreement provides for an additional $25,000 last out Revolving B Credit Facility (the "Revolving B Credit Facility" and together with the Revolving A Credit Facility, the "Credit Facility"). The Credit Facility was made available in part by way of a participation in the Revolving B Credit Facility by certain of the Company’s stockholders. Borrowings under the Credit Facility will mature on February 28, 2022.

Table of Contents

Subject to certain exceptions and permitted encumbrances, the obligations under the ABL Credit Agreement are secured by a first priority security interest in substantially all of the assets of each of the Borrowers and certain subsidiaries of the Company that are named as guarantors. The proceeds of the advances under the ABL Credit Agreement may only be used to (i) pay certain fees and expenses to the Agent and the lenders under the ABL Credit Agreement, (ii) provide for the Borrowers' working capital needs and reimburse drawings under letters of credit, (iii) repay the obligations under the Debtor-in-Possession Revolving Credit and Security Agreement dated as of July 10, 2017, by and among the Company, the lenders party thereto, and PNC, and certain other existing indebtedness, and (iv) provide for the Borrowers' capital expenditure needs, in accordance with the ABL Credit Agreement.

The Company may prepay its obligations under the ABL Credit Agreement at any time without premium or penalty, and must apply the net proceeds of material sales of collateral in prepayment of such obligations. Payments made must be applied to the Company's obligations under the Revolving A Credit Facility, if any, prior to its obligations under the Revolving B Credit Facility. In connection with an early termination or permanent reduction of the Revolving A Credit Facility prior to March 27, 2021, a 0.50% fee shall be due and, for the period from March 28, 2021 through September 27, 2021, a 0.25% fee shall be due, in each case in the amount of such commitment reduction, subject to reduction as set forth in the ABL Credit Agreement. Indebtedness for borrowings under the ABL Credit Agreement is subject to acceleration upon the occurrence of specified defaults or events of default, including (i) failure to pay principal or interest, (ii) the inaccuracy of any representation or warranty of a loan party, (iii) failure by a loan party to perform certain covenants, (iv) defaults under indebtedness owed to third parties, (v) certain liability producing events relating to ERISA, (vi) the invalidity or impairment of the Agent’s lien on its collateral or of any applicable guarantee, and (vii) certain adverse bankruptcy-related and other events.

Interest on indebtedness under the Revolving A Credit Facility accrues at a variable rate based on a grid with the highest interest rate being the applicable LIBOR-based rate plus a margin of 3.0%, as set forth in the ABL Credit Agreement. Interest on indebtedness under the Revolving B Credit Facility accrues at a rate of 12.0% per annum, which will be paid in kind unless the Company elects to pay such interest in cash and the Revolving B payment conditions specified in the ABL Credit Agreement are satisfied. Additionally, the Company must pay a monthly facility fee equal to the product of (i) 0.25% per annum (or, if the average daily revolving facility usage is less than 50% of the maximum revolving advance amount, 0.375% per annum) multiplied by (ii) the amount by which the maximum revolving advance amount exceeds such average daily revolving facility usage for such month.

The weighted average interest rate on outstanding borrowings under the Revolving A Credit Facility for the three and nine months ended September 30, 2020 was 3.26% and 3.83%, respectively, and 5.29% and 5.47% for the three and nine months ended September 30, 2019, respectively. The weighted average facility fee for each such period was 0.25%. The Company pays certain customary recurring fees with respect to the ABL Credit Agreement. Interest expense related to the Revolving B Credit Facility of $840 and $2,428 was paid in kind in the three and nine months ended September 30, 2020. Interest expense related to the Revolving B Credit Facility of $744 and $2,145 was paid in kind in the three and nine months ended September 30, 2019, respectively.

The ABL Credit Agreement includes negative covenants customary for an asset-based revolving loan. Such covenants include limitations on the ability of the Borrowers to, among other things, (i) effect mergers and consolidations, (ii) sell assets, (iii) create or suffer to exist any lien, (iv) make certain investments, (v) incur debt and (vi) transact with affiliates. In addition, the ABL Credit Agreement includes customary affirmative covenants for an asset-based revolving loan, including covenants regarding the delivery of financial statements, reports and notices to the Agent. The ABL Credit Agreement also contains customary representations and warranties and event of default provisions for a secured term loan.

The Company's ABL Credit Agreement contains a springing financial maintenance covenant requiring the Company to maintain a Fixed Charge Coverage Ratio of 1.0 to 1.0 in any Covenant Testing Period (as defined in the ABL Credit Agreement) when the Company's cash liquidity (as defined in the ABL Credit Agreement) is less than $12,500. The Company was not in a Covenant Testing Period as of and for the three and nine months ended September 30, 2020.

Unamortized debt issuance costs of $189 associated with the ABL Credit Agreement were recorded as a reduction in long-term debt as of September 30, 2020.

Convertible Senior Secured Notes

On March 27, 2020, the Company completed an exchange offer and consent solicitation (the “Exchange Offer”) to issue its 3.00%/5.00% Convertible Notes and shares of its common stock in exchange for its 5.00%/7.00%

Table of Contents

Convertible Notes, including any accrued and unpaid interest on the 5.00%/7.00% Convertible Notes as of the date in which the Exchange Offer was completed. Pursuant to the terms of the Exchange Offer, $190,200 in aggregate principal amount of the 5.00%/7.00% Convertible Notes were tendered and accepted and in exchange, the Company issued $95,135 in aggregate principal amount of its 3.00%/5.00% Convertible Notes and 70,261 shares of its common stock. The 3.00%/5.00% Convertible Notes are guaranteed on a senior basis by all current and future domestic subsidiaries (other than those designated as "unrestricted subsidiaries") of the Company (the "Guarantors"). An aggregate principal amount of 5.00%/7.00% Convertible Notes in the amount of $3,693 were not tendered and remained outstanding at the date of Exchange Offer.

The 3.00%/5.00% Convertible Notes have substantially the same terms that the 5.00%/7.00% Convertible Notes had prior to the completion of the Exchange Offer except for the following primary differences: (i) the 3.00%/5.00% Convertible Notes are not exempt from the registration requirements of the Securities Act of 1933, as amended, and have the benefit of registration rights to the holders of the 3.00%/5.00% Convertible Notes, (ii) the interest on the 3.00%/5.00% Convertible Notes accrues at the rate of 3.00% per annum if paid in cash and at the rate of 5.00% per annum if paid in kind, compared to interest on the 5.00%/7.00% Convertible Notes, which accrues at the rate of 5.00% per annum if paid in cash and at the rate of 7.00% per annum if paid in kind, and (iii) the 3.00%/5.00% Convertible Notes have a maturity date of August 31, 2024, compared to the 5.00%/7.00% Convertible Notes, which have a maturity date of August 31, 2022.

In conjunction with the Exchange Offer, on March 27, 2020, the Company, the guarantors of the 5.00%/7.00% Convertible Notes and the trustee for the 5.00%/7.00% Convertible Notes entered into a supplemental indenture to the indenture governing the 5.00%/7.00% Convertible Notes (the “5.00%/7.00% Convertible Notes Indenture”) to provide for, among other things, the elimination or amendment of substantially all of the restrictive covenants, the release of all collateral securing the Company’s obligations under the 5.00%/7.00% Convertible Notes Indenture, and the modification of certain of the events of default and various other provisions contained in the 5.00%/7.00% Convertible Notes Indenture (the "Supplemental Indenture").

Also on March 27, 2020, PNC (in its capacity as “First Lien Agent”), the trustee for the 5.00%/7.00% Convertible Notes and the Company and certain of its subsidiaries executed an intercreditor agreement (the “New Intercreditor Agreement”) providing for the lien priority of the first lien facility over the 3.00%/5.00% Convertible Notes. The terms and conditions of the New Intercreditor Agreement are substantially consistent with those applicable to the intercreditor agreement between the First Lien Agent and the trustee for the 5.00%/7.00% Convertible Notes prior to the completion of the Exchange Offer (the “5.00%/7.00% Convertible Notes Intercreditor Agreement”). PNC and the trustee for the 5.00%/7.00% Convertible Notes also entered into an amendment of the 5.00%/7.00% Convertible Notes Intercreditor Agreement to, among other things, remove certain limitations and rights of the 5.00%/7.00% Convertible Notes with respect to the first lien facility.

The 3.00%/5.00% Convertible Notes were issued pursuant to an indenture (the “3.00%/5.00% Convertible Notes Indenture”), which the Company and the Guarantors entered into with Wilmington Savings Fund Society, FSB, as trustee and collateral agent ("Indenture Agent"), on March 27, 2020. The 3.00%/5.00% Convertible Notes are, secured by a lien on all or substantially all of the assets of the Company, its domestic subsidiaries and certain of its foreign subsidiaries, which lien the Indenture Agent has agreed will be junior to the lien of the Agent under the ABL Credit Agreement.

The 3.00%/5.00% Convertible Notes are convertible into shares of the Company’s common stock at any time at the initial conversion price of $0.46 per share, which rate is subject to adjustment as set forth in the 3.00%/5.00% Convertible Notes Indenture. Under the 3.00%/5.00% Convertible Notes Indenture, upon the conversion of the 3.00%/5.00% Convertible Notes in connection with a Fundamental Change (as defined in the 3.00%/5.00% Convertible Notes Indenture), for each $1.00 principal amount of the 3.00%/5.00% Convertible Notes, that number of shares of the Company’s common stock issuable upon conversion shall equal the greater of (a) $1.00 divided by the then applicable conversion price or (b) $1.00 divided by the price paid per share of the Company's common stock in connection with such Fundamental Change calculated in accordance with the 3.00%/5.00% Convertible Notes Indenture, subject to other provisions of the 3.00%/5.00% Convertible Notes Indenture. Subject to certain exceptions, under the 3.00%/5.00% Convertible Notes Indenture a “Fundamental Change” includes, but is not limited to, the following: (i) the acquisition of more than 50% of the voting power of the Company’s common equity by a “person” or “group” within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as amended; (ii) the consummation of any recapitalization, reclassification, share exchange, consolidation or merger of the Company pursuant to which the Company’s common stock will be converted into cash, securities or other property; (iii) the “Continuing Directors” (as defined in the 3.00%/5.00% Convertible Notes Indenture) cease to constitute at

Table of Contents

least a majority of the board of directors; and (iv) the approval of any plan or proposal for the liquidation or dissolution of the Company by the Company’s stockholders.

The 5.00%/7.00% Convertible Notes are convertible into shares of the Company’s common stock at any time at the initial conversion price of $3.77 per share, which rate is subject to adjustment as set forth in the Supplemental Indenture. Under the Supplemental Indenture, the conversion of the 5.00%/7.00% Convertible Notes in connection with a Fundamental Change (as defined in the Supplemental Indenture) is substantially the same as under the 3.00%/5.00% Convertible Notes Indenture, other than the applicable conversion price.

Upon conversion of the 3.00%/5.00% Convertible Notes and/or the 5.00%/7.00% Convertible Notes, the Company will pay and/or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, together with cash in lieu of fractional shares. The value of shares of the Company’s common stock for purposes of the settlement of the conversion right, if the Company elects to settle in cash, will be calculated as provided in the 3.00%/5.00% Convertible Notes Indenture or Supplemental Indenture, as applicable, using a 20 trading day observation period.

As discussed previously, the 3.00%/5.00% Convertible Notes are convertible into common stock at the option of the holder. As of March 27, 2020, the date of the Exchange Offer, the Company determined that the conversion option was not clearly and closely related to the economic characteristics of the 3.00%/5.00% Convertible Notes, nor did the conversion option meet the own equity scope exception as the Company did not have sufficient authorized and unissued common stock shares to satisfy the maximum number of common stock shares that could be required to be issued upon conversion. As a result, the Company concluded that the embedded conversion option must be bifurcated from the 3.00%/5.00% Convertible Notes, separately valued, and accounted for as a derivative liability, which was classified in long term debt and marked to fair value through earnings.

The 3.00%/5.00% Convertible Notes are fully and unconditionally guaranteed, jointly and severally, by certain subsidiaries of the Company. The 3.00%/5.00% Convertible Notes and the related guarantees are secured by a lien on substantially all of the Company’s and the guarantors’ assets, subject to certain exceptions pursuant to certain collateral documents pursuant to the 3.00%/5.00% Convertible Notes Indenture. The terms of the 3.00%/5.00% Convertible Notes contain numerous covenants imposing financial and operating restrictions on the Company's business. These covenants place restrictions on the Company’s ability and the ability of its subsidiaries to, among other things, pay dividends, redeem stock or make other distributions or restricted payments; incur indebtedness or issue certain stock; make certain investments; create liens; agree to certain payment restrictions affecting certain subsidiaries; sell or otherwise transfer or dispose assets; enter into transactions with affiliates; and enter into sale and leaseback transactions.

Neither the 3.00%/5.00% Convertible Notes nor the 5.00%/7.00% Convertible Notes may be redeemed by the Company in whole or in part at any time prior to maturity, except the Company may be required to make an offer to purchase the 3.00%/5.00% Convertible Notes using the proceeds of certain material asset sales involving the Company or one of its restricted subsidiaries, as described more particularly in the 3.00%/5.00% Convertible Notes Indenture. In addition, if a Fundamental Change (as defined in the 3.00%/5.00% Convertible Notes Indenture and the Supplemental Indenture, as applicable) occurs at any time, each holder of any 3.00%/5.00% Convertible Notes or 5.00%/7.00% Convertible Notes has the right to require the Company to repurchase such holder’s notes for cash at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest thereon, subject to certain exceptions.

The Company must use the net proceeds of material sales of collateral, which proceeds are not used for other permissible purposes, to make an offer of repurchase to holders of the 3.00%/5.00% Convertible Notes. Indebtedness for borrowings under the 3.00%/5.00% Convertible Notes Indenture and the Supplemental Indenture is subject to acceleration upon the occurrence of specified defaults or events of default as set forth under each such indenture, including failure to pay principal or interest, the inaccuracy of any representation or warranty of any

Table of Contents

obligor, failure by an obligor to perform certain covenants, the invalidity or impairment of the Agent’s lien on its collateral under the 3.00%/5.00% Convertible Notes Indenture, the invalidity or impairment of any applicable guarantee, and certain adverse bankruptcy-related and other events.

Upon satisfaction of certain conditions more particularly described in the 3.00%/5.00% Convertible Notes Indenture, including the deposit in trust of cash or securities sufficient to pay the principal of and interest and any premium on the 3.00%/5.00% Convertible Notes, the Company may effect a covenant defeasance of certain of the covenants imposing financial and operating restrictions on the Company’s business. In addition, and subject to certain exceptions as more particularly described in the 3.00%/5.00% Convertible Notes Indenture, the Company may amend, supplement or waive provisions of the 3.00%/5.00% Convertible Notes Indenture with the consent of holders representing a majority in aggregate principal amount of the 3.00%/5.00% Convertible Notes, and may in effect release collateral from the liens securing the 3.00%/5.00% Convertible Notes with the consent of holders representing 66.67% in aggregate principal amount of the 3.00%/5.00% Convertible Notes.

Interest on the 3.00%/5.00% Convertible Notes accrues at the rate of 3.00% per annum if paid in cash and at the rate of 5.00% per annum if paid in kind, payable quarterly beginning with the quarter ending June 30, 2020. Interest on the 5.00%/7.00% Convertible Notes continues to accrue at the rate of 5.00% per annum if paid in cash and at the rate of 7.00% per annum if paid in kind, payable quarterly. Pursuant to the terms of both the 3.00%/5.00% Convertible Notes Indenture and the Supplemental Indenture, the Company is currently paying interest on both the 3.00%/5.00% Convertible Notes and the 5.00%/7.00% Convertible Notes in kind. Interest expense related to the 5.00%/7.00% Convertible Notes of $67 and $3,415 was paid in kind in the three and nine months ended September 30, 2020 respectively. Interest expense related to the 5.00%/7.00% Convertible Notes of $3,277 and $9,664 was paid in kind in the three and the nine months ended September 30, 2019, respectively. Interest expense related to the 3.00%/5.00% Convertible Notes of $1,205 and $2,434 was paid in kind in the three and nine months ended September 30, 2020, respectively.

The Company determined that the Exchange Offer was considered to be a troubled debt restructuring within the scope of ASC No. 470-60, "Debt-Troubled Debt Restructurings". Accordingly, for the nine months ended September 30, 2020, the Company has expensed legal and other direct costs incurred in conjunction with the Exchange Offer in the amount of $1,376 in selling, general and administrative expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss and recognized additional legal and other direct costs incurred also in the amount $1,376 as a decrease to additional paid-in capital for the nine months ended September 30, 2020. The Company recorded no legal or other direct costs associated with the Exchange Offer in the three months ended September 30, 2020.

Other long-term debt

The Company qualified under the “alternative size standard” for a forgivable loan under the Paycheck Protection Program (“PPP”) administered by the Small Business Association (SBA) pursuant to the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act. On April 28, 2020, the Company entered into an unsecured PPP loan in the aggregate principal amount of $10,000, which is to be used only for payroll expenses, rent, utilities, mortgage interest, and interest on other pre-existing indebtedness (the "PPP Loan"). After taking into account, among other things, the disruptions to the Company’s business activities caused by the COVID-19 pandemic, the completed Exchange Offer, its available, committed primary sources of liquidity, and its lack of access to alternative sources of liquidity, economic conditions at that time made this loan request necessary and appropriate to support the Company’s ongoing U.S. operations and mitigate potentially significant detriment to the Company’s business. The PPP Loan, which is evidenced by a Paycheck Protection Program Term Note, matures on April 28, 2022 and bears interest at a fixed rate of 1.0% per annum, with the first six months of interest deferred. The PPP Loan is payable in 10 monthly payments commencing on August 15, 2021 and may be prepaid at any time prior to maturity with no prepayment penalties.

Under the terms of the CARES Act and the Paycheck Protection Program Flexibility Act passed on June 5, 2020 (the "PPPFA"), the PPP Loan, and interest accrued thereon, is forgivable, partially or in full, subject to certain conditions, including the extent to which the PPP Loan proceeds are used for permissible purposes within the 24 week period following loan disbursement (which period was extended by the PPPFA from the 8 week period originally allowed by the CARES Act). The Company believes it has used the PPP Loan proceeds for permissible purposes only and intends to apply for forgiveness of the PPP Loan in accordance with the terms of the PPP, the CARES Act and the PPPFA. As of September 30, 2020, the Company has recorded the amount of the PPP Loan due within one year in the current portion of long-term debt and the remainder in long-term debt on the Condensed Consolidated Balance Sheets.

On June 24, 2020, the Company's French subsidiary entered into a €6,000 term loan (the "France Term Loan"). The France Term Loan, which is fully guaranteed by the French government, is part of a relief program related to the COVID-19 pandemic. Similar to the PPP Loan, economic conditions resulting from the COVID-19 pandemic made this France Term Loan necessary and appropriate to support the Company’s ongoing operations in France and mitigate potentially significant detriment to the Company’s business in France. The France Term Loan, which is evidenced by a term note with HSBC Bank, matures on June 24, 2021 and bears no interest. However, in connection with the government guarantee of the France Term Loan, the Company must pay a commission to the French government of 0.5% per annum of the principal loan balance. Under the terms of the France Term Loan, the Company has the option to extend the maturity of the loan for a period of up to five years. As of September 30, 2020, the Company has the intent and ability to extend the maturity of the France Term Loan beyond twelve months and has therefore included the entire outstanding principal balance of the France Term Loan in long-term debt at the Condensed Consolidated Balance Sheets.

Short-term borrowings

On July 20, 2020, the Company's China subsidiary entered into a $3,000 local banking line of credit with the Bank of Communication Shanghai (the "China Credit Facility"). The China Credit Facility has an initial maturity date of January 20, 2021 and accrues interest at a rate of 3.6% per annum. As of September 30, 2020, borrowings under the China Credit Facility of $1,980 were classified as short-term borrowings in the Condensed Consolidated Balance Sheets.

The Company's French subsidiary is party to a local credit facility under which it may borrow against 100% of the eligible accounts receivable factored, with recourse, up to 6,500 Euros. The French subsidiary is charged a factoring fee of 0.16% of the gross amount of accounts receivable factored. Local currency borrowings on the French subsidiary's credit facility are charged interest at the daily 3-months Euribor rate plus a 1.0% margin and U.S dollar borrowings on the credit facility are 3-months LIBOR plus a 1.0% margin. The French subsidiary utilizes the local credit facility to support its operating cash needs. As of September 30, 2020, the French subsidiary had no borrowings under the local credit facility and had borrowings under the local credit facility of $2,888 as of December 31, 2019. The Company records borrowings under the local credit facility as short-term borrowings in the Condensed Consolidated Balance Sheets.

(7) Fair Value Measurements

The three-tier value hierarchy used by the Company, which prioritizes the inputs used in the valuation methodologies, is:

Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3—Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants.

The fair values of cash, accounts receivable and accounts payable approximate their carrying values. The fair value of cash equivalents is determined using the fair value hierarchy described above.

The Company’s pension plan asset portfolio as of September 30, 2020 and December 31, 2019 is primarily invested in fixed income securities, which generally fall within Level 2 of the fair value hierarchy. Fixed income securities are valued based on evaluated prices provided to the trustee of the pension plan by independent pricing services. Such prices may be determined by various factors which include, but are not limited to, market quotations, yields, maturities, call features, ratings, institutional size trading in similar groups of securities and developments related to specific securities.

Fair Value Measurements of Debt

As of September 30, 2020, the fair value of the Company's 3.00%/5.00% Convertible Notes, including the conversion option, was estimated to be $111,052, compared to a face value of $97,568. As of September 30, 2020, the fair value of the Company's 5.00%/7.00% Convertible Notes, including the conversion option, was estimated to

Table of Contents

be $3,457 compared to a face value of $3,890. As of December 31, 2019, the fair value of the Company's 5.00%/7.00% Convertible Notes, including the conversion option, was estimated to be $136,085 compared to a face value of $193,660. The fair value of the 3.00%/5.00% Convertible Notes as of September 30, 2020 and the 5.00%/7.00% Convertible Notes as of December 31, 2019 was determined using a binomial lattice model using assumptions based on market information and historical data, and a review of prices and terms available for similar debt instruments that do not contain a conversion feature, as well as other factors related to the callable nature of the 3.00%/5.00% Convertible Notes, which is a Level 3 input as defined by the fair value hierarchy. The fair value of the 5.00%/7.00% Convertible Notes as of September 30, 2020 was estimated based on a model that discounted future principal and interest payments at interest rates available to the Company at the end of the period for similar debt of the same maturity, which is a Level 2 input as defined by the fair value hierarchy.

The following valuation assumptions were used in determining the fair value of the 3.00%/5.00% Convertible Notes, including the conversion option, as of September 30, 2020:


Risk-free interest rate	0.24	%
Credit spread	9.47	%
PIK premium spread	2.00	%
Volatility	50.00	%

As of September 30, 2020, the fair value of the Company's Revolving B Credit Facility was estimated to be $27,558 compared to a face value of $28,216. As of December 31, 2019, the fair value of the Company's Revolving B Credit Facility was estimated to be $25,082 compared to a face value of $25,788. Also as of September 30, 2020, the fair value of the Company's PPP Loan was estimated to be $8,623 compared to a face value of $10,000 and the fair value of the Company's France Term Loan was estimated to be $3,417 compared to a face value of $7,020. The fair value of the Revolving B Credit Facility, the PPP Loan and the France Term Loan was estimated based on a model that discounted future principal and interest payments at interest rates available to the Company at the end of the period for similar debt of the same maturity, which is a Level 2 input as defined by the fair value hierarchy.

Given the short-term nature and/or the variable interest rates, the fair value of borrowings under the Revolving A Credit Facility and the China Credit Facility approximated their respective carrying values as of September 30, 2020.

Fair Value Measurement of Embedded Conversion Feature

On June 30, 2020, the Company filed articles of amendment to increase the number of shares of common stock authorized (see Note 8 - Stockholders' Equity). As a result of this increase, the number the Company's common stock shares available for issuance upon conversion of the 3.00%/5.00% Convertible Notes is sufficient to allow the conversion option to be share-settled in full. The Company has concluded that as of June 30, 2020, the conversion option qualifies for equity classification and the bifurcated derivative liability will no longer need to be accounted for as a separate derivative on a prospective basis from the date of reassessment. As of June 30, 2020, the fair value of the conversion option of $36,952 was classified to equity as additional paid-in capital. There was no tax impact of the reclassification of the conversion option to equity. The estimated fair value of the derivative liability for the embedded conversion feature of the 3.00%/5.00% Convertible Notes, which falls within Level 3 of the fair value hierarchy, is measured on a recurring basis using a binomial lattice model using the same assumptions as the 3.00%/5.00% Convertible Notes. The following reconciliation represents the change in fair value of the embedded conversion feature of the 3.00%/5.00% Convertible Notes for the nine months ended September 30, 2020. Prior to the reclassification of the embedded conversion feature to additional paid-in capital on June 30, 2020, the Company recognized a gain of $2,010 on the mark-to-fair value adjustment on the embedded debt conversion option.

(8) Stockholders’ Equity

Authorized Shares of Common Stock

On June 30, 2020, the Company's shareholders approved a proposal to amend the Company's charter to authorize an increase in the Company's authorized shares of common stock. Subsequent to this approval, also on June 30, 2020, the Company filed articles of amendment with the Secretary of State of the State of Maryland, which amended its Articles of Amendment and Restatement effective on such date to increase the Company's authorized common stock shares from 200,000 shares of common stock at $0.01 par value per share to 400,000 shares of common stock at $0.01 par value per share. The Company has concluded that as of June 30, 2020 the conversion option qualified for equity classification and the bifurcated derivative liability will no longer need to be accounted for as a separate derivative on a prospective basis from the date of reassessment. On June 30, 2020, the fair value of the conversion option of $36,952 was classified to equity as additional paid-in capital.

Exchange Offer

The Company issued 70,261 shares of its common stock on March 27, 2020 in connection with the Exchange Offer (see Note 6 - Debt). The issuance of these shares was recorded using the fair value of the Company's common stock on the date the shares were issued and resulted in an increase in the par value of common stock and additional paid-in capital of $703 and $24,606, respectively. The shares were issued in exchange for 5.00%/7.00% Convertible Notes, and, as such, the Company received no cash proceeds as part of the exchange.

(9) Share-based Compensation

Restricted Shares

The Company's Board of Directors (the "Board") has issued restricted shares of the Company's common stock ("Restricted Shares") and restricted 5.00%/7.00% Convertible Notes (the "Restricted 5.00%/7.00% Convertible Notes") to certain officers of the Company, as well as Restricted Shares to certain members of the Board. On March 27, 2020, in conjunction with the Exchange Offer, the Company issued restricted 3.00%/5.00% Convertible Notes (the "Restricted 3.00%/5.00% Convertible Notes") and Restricted Shares in exchange for all of the outstanding Restricted 5.00%/7.00% Convertible Notes, including any accrued and unpaid interest on the Restricted 5.00%/7.00% Convertible Notes as of the date in which the Exchange Offer was completed (the "Restricted Note Exchange"). Pursuant to the Restricted Note Exchange, $1,613 in aggregate principal amount of the Restricted 5.00%/7.00% Convertible Notes were tendered and accepted and in exchange, the Company issued $793 in aggregate principal amount of Restricted 3.00%/5.00% Convertible Notes and 586 shares of Restricted Shares. The Restricted 3.00%/5.00% Convertible Notes outstanding were convertible into an additional 1,740 shares of the Company's common stock as of September 30, 2020.

The Restricted Shares granted to certain officers of the Company on September 1, 2017 cliff vested on August 31, 2020. As they relate to the first tranche of Restricted 5.00%/7.00% Convertible Notes, the Restricted 3.00%/5.00% Convertible Notes and Restricted Shares issued as a result of the Restricted Note Exchange also cliff vested on August 31, 2020. As they relate to the second tranche of Restricted 5.00%/7.00% Convertible Notes, which were made available as lapsed incentive awards and awarded to certain officers of the Company on March 25, 2020, the Restricted 3.00%/5.00% Convertible Notes, and Restricted Shares issued as a result of the Restricted Note Exchange cliff vest on August 31, 2024.

Table of Contents

A summary of the activity of the Company's Restricted Shares as of September 30, 2020 and in the nine months then ended follows:



	Shares	Weighted-Average Grant Date Fair Value
Outstanding at January 1, 2020	1,429	$	3.13
Issued upon exchange of Restricted 5.00%/7.00% Convertible Notes	586	0.38
Forfeited	—	—
Vested	(1,899)	3.14
Outstanding at September 30, 2020	116	0.56
Expected to vest after September 30, 2020	116	0.56

Performance Share Units

The Board has granted performance share units ("PSUs") as awards under the MIP to non-executive senior level managers and other select personnel. The PSUs contain a performance-based condition tied to the enterprise value of the Company. Each PSU that vests entitles the participant to receive, at the discretion of the Company's Board, one share of the Company's common stock or cash equal to the fair market value of one share of the Company's common stock. Vesting occurs upon achievement of a defined enterprise value of the Company, with 50% vesting upon achievement of the defined enterprise value between the performance period September 30, 2020 and September 30, 2022, and the remaining 50% vesting upon the achievement of the defined enterprise value as a result of a specified transaction, as defined in the PSU agreement, on or before September 30, 2022.

As of September 30, 2020, there were 762 PSUs outstanding.

Share-Based Compensation Expense

Compensation expense recognized related to the PSUs is based on management’s expectation of future performance compared to the pre-established performance goals. If the performance goals are not expected to be met, no compensation expense is recognized and any previously recognized compensation expense is reversed. As of September 30, 2020, no compensation expense was recognized for these awards to date as the threshold for expense recognition for the performance-based condition had not been met.

As of September 30, 2020, the unrecognized share-based compensation expense related to unvested Restricted Shares was $45 and is expected to be recognized over a weighted-average period of approximately 1.8 years. Forfeitures are accounted for as they occur.

As of September 30, 2020, the unrecognized share-based compensation expense related to the outstanding Restricted 3.00%/5.00% Convertible Notes was $109 and is expected to be recognized over a weighted-average period of approximately 1.9 years. The Company will recognize this compensation expense on a straight-line basis over the remaining vesting period using the fair value of the Restricted 3.00%/5.00% Convertible Notes at the Restricted Note Exchange date.

The Company anticipates making no additional cash contributions to its pension plans in the remainder of 2020.

The Company was party to a multi-employer pension plan from which the Company determined to withdraw. At September 30, 2020, the total estimated liability to withdraw from the plan was $3,028. The current liability associated with the Company's withdrawal from the multi-employer pension plan of $240 is included in accrued and other current liabilities in the Condensed Consolidated Balance Sheets and the long-term liability of $2,788 is included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets.

(11) Income Taxes

The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items. The Company’s effective tax rate is expressed as income tax benefit as a percentage of loss before income taxes.

On March 27, 2020, the U.S. federal government signed into law the CARES Act, to provide economic relief to U.S. companies impacted by the COVID-19 pandemic. Pursuant to the provisions of the CARES Act, the Company filed a carryback claim to utilize its net operating losses from 2019 to offset taxable net income realized in 2018.

In the three months ended September 30, 2020, the Company recorded income tax benefit of $572 on a loss before income taxes of $15,316, for an effective tax rate of 3.7%. In the three months ended September 30, 2019, the Company recorded income tax benefit of $1,079 on a loss before income taxes of $13,275, for an effective tax rate of 8.1%.

In the nine months ended September 30, 2020, the Company recorded income tax benefit of $3,163 on a loss before income taxes of $33,001, for an effective tax rate of 9.6%. In the nine months ended September 30, 2019, the Company recorded income tax benefit of $1,479 on a loss before income taxes of $29,982, for an effective tax rate of 4.9%.

The most significant factors impacting the effective tax rate in the three months ended September 30, 2020 were (i) the recording of the period expense associated with the quasi territorial tax regime called the Global Intangible Low Taxed Income Inclusion (“GILTI”), (ii) the foreign rate differential, and (iii) changes in valuation allowances in the United States and Canada. Also impacting the effective tax rate in the nine months ended September 30, 2020 was the increase in net operating loss carrybacks due to the CARES Act.

The Company's U.S. federal corporate income tax rate is 21%.

(12) Commitments and Contingent Liabilities

From time to time, the Company is party to a variety of legal proceedings, claims, and inquiries, including proceedings or inquiries by governmental authorities, which arise from the operation of its business. These proceedings, claims, and inquiries are incidental to and occur in the normal course of the Company's business affairs. The majority of these proceedings, claims, and inquiries relate to commercial disputes with customers, suppliers, and others; employment and employee benefits-related disputes; product quality disputes with vendors and/or customers; and environmental, health and safety claims. Although the outcome of these proceedings is inherently difficult to predict, management believes that the amount of any judgment, settlement or other outcome of these proceedings, claims and inquiries, after taking into account recorded accruals and the availability and limits of our insurance coverage, will not have a material adverse effect on the Company’s consolidated results of operations, financial condition or cash flows.

(13) Subsequent Events (share and cash payment in lieu of fractional share amounts are presented as whole numbers)

On October 30, 2020, the Company announced that it will effect a reverse split of the Company’s outstanding shares of common stock (the “Common Stock”), pursuant to Section 2-309(e) of the Maryland General Corporation Law, whereby each 10 shares of Common Stock issued and outstanding as of the effective date of the reverse stock split will be combined into one whole share of Common Stock (the “Reverse Stock Split”). No fractional shares of Common Stock will be issued as a result of the Reverse Stock Split. In lieu of issuing any fractional shares to any stockholder as a result of the Reverse Stock Split, the Company will make, to any stockholder that would otherwise hold a fractional share after giving effect to the Reverse Stock Split, a cash payment in an amount equal to $0.70 multiplied by the number of pre-split shares held by such stockholder with respect to which a fractional share would be issued, which represents a premium of approximately 70% over the 20-day VWAP (volume weighted average price) of the Common Stock on the Best Market tier of the OTC Markets Group, Inc. beginning on October 9, 2020

Table of Contents

and ending on October 28, 2020. The Company expects the Reverse Stock Split to be completed in the fourth quarter of 2020 or early in the first quarter of 2021.

On November 16, 2020, the Company announced it had reached an agreement in principle with its first lien lender, PNC, and certain of its stockholders to provide for a new $8,000 term loan (the "Revolving B Term Loan") from such stockholders, subordinated only to the Revolving A Credit Facility. The Revolving B Term Loan will accrue at a rate of 15.0% per annum, which will be paid-in-kind unless the Company qualifies and elects to pay such interest in cash. As part of this agreement in principle, the Company and PNC also agreed to extend the maturity date of the Revolving A Credit Facility to February 28, 2023, and to (i) amend certain aspects of the facility to lower the minimum (on-hand) liquidity requirement that the Company must maintain by $3,750 under the terms the Revolving A Credit Facility, and (ii) increase the interest rate applicable to the Revolving Credit A Facility to LIBOR-base rate plus a margin of 4.0%. The agreement in principle is subject to customary conditions to closing, including execution of acceptable documentation and final approval, which the Company expects to occur during the fourth quarter of 2020.

The Company expects to pay an amendment fee of 0.20% on the $125,000 borrowing capacity of the amended Revolving A Credit Facility.

Overview

A. M. Castle & Co., together with its subsidiaries (the “Company,” “we” or “us”), is a global distributor of specialty metals and supply chain services, principally serving the producer durable equipment, commercial and military aircraft, heavy equipment, industrial goods, and construction equipment sectors of the global economy. The Company provides a broad range of product inventories as well as value-added processing and supply chain services to a wide array of customers, with a particular focus on the aerospace and defense, power generation, mining, heavy industrial equipment, and general manufacturing industries, as well as general engineering applications.

Impact of Coronavirus (COVID-19) Pandemic

Although there were some signs of recovery in the third quarter of 2020, the significantly lower demand for the Company's products experienced in the prior quarter continued into the third quarter as many of the industries the Company serves continue to be impacted economically, some significantly, by the novel coronavirus 2019 ("COVID-19") pandemic. The global health crisis caused by the COVID-19 pandemic continues to result in a decline in orders from and shipments to customers compared to pre-pandemic levels, as well as slower-than-normal payments from customers and disruptions at certain of the Company's suppliers. In addition, the pricing environment for the Company's products continues to be extremely competitive with lower average price per ton sold in the third quarter on both a quarter-over-quarter and year-over-year basis. The Company anticipates the recovery in economic activity to pre-pandemic levels will be slower than originally expected as its customers and suppliers struggle to return their own businesses to pre-pandemic levels. The Company expects COVID-19 to continue to have an unfavorable impact on its financial results and business in the fourth quarter of 2020, which is historically a seasonally slow quarter, and into 2021.

To date, the Company has taken actions to maintain operations through the pandemic and its network as a whole has remained operational, albeit at varying levels of volume aligned to customer orders and forecasts. The Company has prepared and regularly updates business continuity plans for ongoing operations and has taken steps to adjust its business to match the deteriorating economic conditions, including the implementation of enhanced

measures through its global supply and branch management teams to ensure the Company is efficiently utilizing inventory on hand and inbound, as well as its internal processing capabilities.

Given the expectation that the recovery to pre-pandemic levels may be longer than originally expected, the Company has begun to implement a long-term, permanently sustainable cost structure that does not rely on temporary cost reduction measures as significantly as those relied on during the early stages of the pandemic. The Company believes the permanent cost-cutting measures being implemented will not only align the Company with current demand, but also better prepare it for any market recovery once this pandemic has passed. Permanent cost-cutting measures, which are estimated to reduce the Company's operating expenses by at least $15.0 million on an annualized basis, primarily include staff reductions through layoffs, which were implemented in conjunction with the elimination of most of the temporary cost measures taken previously, including the temporary reduction in employee hours and/or salaries, deferral of periodic salary increases and/or incentive pay, and/or a combination of these actions. In an effort to protect the health and safety of its employees, the Company has adopted sanitization, social distancing and other behavioral best practices at its locations, including remote work arrangements, reducing the number of people in the Company's branch and corporate locations at any one time, and suspending non-essential employee travel. At the outset of the COVID-19 pandemic, the Company established a COVID-19 response team to closely monitor the local, regional, and national situations that impact the Company's various branches, monitor and advise on COVID-19 exposures and potential exposures within the Company's workspaces, direct and implement health and safety plans and business continuity plans, and establish pandemic-related guidelines and policies to best protect the Castle team and its business, including responsible return-to-work or restart plans. Variables that the Company is taking into consideration as some branches and the Corporate office begin to return to normal operations include local case trends, testing availability, number of employees and the workstation layout, productivity and engagement concerns, and most importantly, guidance and requirements from local, state, and federal government, medical and scientific authorities.

In an effort to bolster its liquidity position and mitigate potentially significant detriment to its business, the Company has and will continue to pursue a variety of government-sponsored support programs, such as tax deferrals, employment-related subsidies, government-backed loans and other government relief available in the U.S. and in other countries in which it operates. Actual relief under each of these measures varies in terms of timing and availability as governments continue to define, implement, extend and/or fund their relief programs.

The Company qualified under the “alternative size standard” for a forgivable loan under the Paycheck Protection Program (“PPP”) administered by the Small Business Association (SBA) pursuant to the CARES Act. On April 28, 2020, the Company entered into an unsecured PPP loan in the aggregate principal amount of $10.0 million, which is to be used only for payroll expenses, rent, utilities, mortgage interest, and interest on other pre-existing indebtedness (the "PPP Loan"). After taking into account, among other things, the disruptions to the Company’s business activities caused by the COVID-19 pandemic, the completed exchange offer and consent solicitation (the “Exchange Offer”) to issue its 3.00% / 5.00% Convertible Senior Secured Paid-in-Kind ("PIK") Toggle Notes due 2024 (the “3.00% / 5.00% Convertible Notes”) and shares of its common stock in exchange for its 5.00% / 7.00% Convertible Senior Secured PIK Toggle Notes due 2022 (the “5.00% / 7.00% Convertible Notes”), its available, committed primary sources of liquidity, and its lack of access to alternative sources of liquidity, economic conditions at that time made this loan request necessary and appropriate to support the Company’s ongoing U.S. operations and mitigate potentially significant detriment to the Company’s business. Under the terms of the CARES Act and the Paycheck Protection Program Flexibility Act passed on June 5, 2020 (the "PPPFA"), the PPP Loan, and interest accrued thereon, is forgivable, partially or in full, subject to certain conditions, including the extent to which the PPP Loan proceeds are used for permissible purposes within the 24 week period following loan disbursement (which period was extended by the PPPFA from the 8 week period originally allowed by the CARES Act). The Company believes it has used the PPP Loan proceeds for permissible purposes only and intends to apply for forgiveness of the full amount of the PPP Loan in accordance with the terms of the PPP, the CARES Act and the PPPFA.

and has therefore included the entire outstanding principal balance of the France Term Loan in long-term debt at the Condensed Consolidated Balance Sheets.

The Company will continue to actively monitor the situation as it relates to the COVID-19 pandemic and may take further actions altering the Company's business operations that we determine are in the best interests of the Company's employees, customers, business partners, suppliers, and shareholders, or as required by federal, state, or local authorities. It is not clear what the potential effects any such alterations or modifications may have on the Company's business, including the effects on the Company's customers, employees, and prospects, or on the Company's financial results for the remainder of fiscal 2020 or beyond.

Net Sales

Net sales of $79.5 million in the three months ended September 30, 2020 decreased $56.6 million, or 41.6%, compared to $136.1 million in the three months ended September 30, 2019. Net sales of $290.9 million in the nine months ended September 30, 2020 decreased $142.7 million, or 32.9%, compared to $433.6 million in the nine months ended September 30, 2019. The decrease in net sales in both the three and nine months ended September 30, 2020 compared to the same periods in the prior year was driven primarily by the macroeconomic impacts of the COVID-19 pandemic, which worsened already soft industrial end markets and further weakened demand for global aerospace products. The weakening of demand within the aerospace market is largely attributable to the impact of the COVID-19 pandemic on global air travel and the grounding of the Boeing 737 MAX, for which some of the Company's locations have customers that supply content. Tons sold per day for the Company's products decreased by 33.7% in the three months ended September 30, 2020 compared to the same quarter in the prior year and 31.4% in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019.

In the three months ended September 30, 2020 and the nine months ended September 30, 2020, overall average selling prices of the Company's product mix sold decreased 12.7% and 2.7%, respectively, compared to the same periods in 2019. The macroeconomic impact of the COVID-19 pandemic has resulted in a decrease in demand and availability of supply, which has led to increased price competition for all of the Company's core products. With the exception of aluminum, which had an increase in price per ton sold, the price per ton sold decreased for all of the products the Company sells in the three months ended September 30, 2020 and the nine months ended September 30, 2020, compared to the same periods in 2019.

The Company expects a long and slow market recovery to pre-pandemic levels. As a result, the Company believes that the unfavorable financial and business impacts of the pandemic that were experienced in the second and third quarters of 2020 will continue into the fourth quarter of 2020 and into 2021 as the Company's customers and suppliers continue to maintain reduced purchasing forecasts and output. In turn, the Company's expects the decrease in demand and availability and increase in competition in the markets that the Company serves to continue for the remainder of 2020 and into 2021.

Cost of Materials

Cost of materials (exclusive of depreciation) was $58.6 million in the three months ended September 30, 2020 compared to $103.0 million in the three months ended September 30, 2019. The $44.4 million, or 43.1%, decrease in the third quarter of 2020 compared to the third quarter of 2019 is primarily due to the decrease in net sales volume compared to the same period last year. Cost of materials (exclusive of depreciation) was 73.7% of net sales in the three months ended September 30, 2020 compared to 75.7% of net sales in the three months ended September 30, 2019.

Cost of materials (exclusive of depreciation) was $211.8 million in the nine months ended September 30, 2020 compared to $323.9 million in the nine months ended September 30, 2019, a decrease of $112.1 million, or 34.6%. Cost of materials (exclusive of depreciation) was 72.8% of net sales in the nine months ended September 30, 2020 compared to 74.7% of net sales in the nine months ended September 30, 2019.

The Company's focus on selectively pursuing higher margin sales that are more accretive to the business, particularly those including the Company's value added service offerings, resulted in sales of products with higher gross material margins (calculated as net sales less cost of materials divided by net sales) in both the three and nine months ended September 30, 2019, compared to the same periods last year. The Company expects its margins will remain relatively stable for the remainder of 2020 as its improved inventory management partially offsets the headwinds produced by reduced demand, a downward pricing environment and the unfavorable impacts of the COVID-19 pandemic on the overall global economy.

Operating Costs and Expenses and Operating Loss

In response to the unfavorable global economic conditions resulting from the COVID-19 pandemic, the Company began early in the second quarter of 2020 to take steps to align its operating costs and expenses with the decrease in customer and supplier forecasts and output, including the temporary reduction in employee hours and salaries, deferral of periodic salary increases and incentive pay, or a combination of these actions. As a result of the slower-than-expected recovery, the Company has elected to make many of the cost reduction steps permanent as it moves toward a permanently sustainable cost structure aligned for a longer period of reduced customer demand. The permanent steps taken by management include reductions in discretionary spending and additional staff reductions through layoffs at each of its branches and at its corporate offices. In addition, for the safety of its employees, the Company has suspended non-essential employee travel. The cost-cutting measures taken by the Company to date have resulted in a significant decrease in operating costs and expenses in the three and nine months ended September 30, 2020 compared to the same periods last year. The Company expects the permanent cost-cutting measures taken, which were primarily implemented in the latter half of September 2020, to result in a further decrease in operating costs and expenses in future periods.

Operating costs and expenses decreased by $5.4 million, or 14.6%, from $36.9 million in the three months ended September 30, 2019 to $31.5 million in the three months ended September 30, 2020, primarily as a result of the following:

•Warehouse, processing and delivery expense decreased by $5.4 million primarily due to a lower payroll and benefits costs and lower warehouse and freight costs in the three months ended September 30, 2020 compared to the same period last year. The 28.7% decrease was driven by cost cutting measures taken by the Company in response to the COVID-19 pandemic, as well as lower sales volume.

•Sales, general and administrative expense decreased by $2.5 million, primarily the result of lower payroll and benefits costs, as well as other reductions in employee expenses and discretionary spending in the three months ended September 30, 2020 compared to the three months ended September 30, 2019 driven mainly by the cost cutting measures taken by the Company in response to the COVID-19 pandemic, including staff reductions, reductions in employee work hours and/or salaries, furloughs, temporary layoffs, deferral of periodic salary increases and/or incentive pay, or a combination of these actions. The decreases were partially offset by severance costs of approximately $0.7 million and by legal and other direct fees of $0.3 million associated with the filing of a registration statement for the registration of additional shares of the Company's common stock.

•As described in Note 5, Goodwill and Other Intangibles, to the Notes to the Condensed Consolidated Financial Statements, due to the ongoing unfavorable economic impacts of the COVID-19 pandemic, which represented facts and circumstances indicating that it was likely that its goodwill and indefinite lived trade name intangible assets could be impaired, the Company performed an assessment of its goodwill as of September 30, 2020. As a result of the goodwill impairment assessment, the Company recorded a non-cash impairment charge of $2.7 million during the third quarter of fiscal 2020. The Company has no remaining goodwill as a result of the charge recognized in the period. This non-cash impairment charge does not result in any future cash expenditures, impact liquidity, affect ongoing business or financial performance of the Company, impact compliance with our lending arrangements or reduce borrowing capacity.

•Warehouse, processing and delivery expense decreased by $14.0 million primarily due to lower payroll and benefits costs and lower warehouse and freight costs in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019. The 23.5% decrease was driven by cost cutting measures taken by the Company beginning in the second quarter of 2020 in response to the COVID-19 pandemic, as well as lower sales volume.

Table of Contents

•Sales, general and administrative expense decreased by $7.2 million primarily the result of lower payroll and benefits costs in the nine months ended September 30, 2020 compared to nine months ended September 30, 2019 driven mainly by the cost cutting measures taken by the Company in response to the COVID-19 pandemic, including staff reductions, reductions in employee work hours and/or salaries, furloughs, temporary layoffs, deferral of periodic salary increases and/or incentive pay, or a combination of these actions. The decreases were partially offset by legal and other direct fees associated with the Exchange Offer in the amount of $1.4 million, severance costs of approximately $0.7 million, and legal and other direct fees of $0.3 million associated with the filing of a registration statement for the registration of additional shares of the Company's common stock.

•As described above, the Company recorded a non-cash goodwill impairment charge in the three and nine months ended September 30, 2020.

Operating loss in the three months ended September 30, 2020 was $10.6 million, compared to $3.8 million in the three months ended September 30, 2019. Operating loss in the nine months ended September 30, 2020 was $17.1 million, compared to $5.3 million in the nine months ended September 30, 2019.

Other Income and Expense, Income Taxes and Net Loss

Interest expense, net was $5.1 million in the three months ended September 30, 2020, compared to $10.2 million in the three months ended September 30, 2019. Interest expense includes the interest cost component of the net periodic benefit cost of the Company's pension and post retirement benefits of $1.0 million in the three months ended September 30, 2020 and $1.3 million in the three months ended September 30, 2019. As a result of the Exchange Offer, the Company reduced the aggregate principal amount of its long-term debt by $94.5 million and expects to reduce its annual interest expense by over $10.0 million. The decrease in interest expense in the three months ended September 30, 2020 compared to the three months ended September 30, 2019 is primarily due to a decrease in the overall non-cash interest expense on outstanding convertible debt as a result of the Exchange Offer of $2.0 million, a decrease in non-cash amortization of the outstanding convertible debt of $2.2 million, and a decrease in interest expense on the Company's variable rate revolving credit facility of $0.7 million as a result of both a lower revolving credit facility borrowings and a lower effective interest rate on revolving credit facility borrowings.

Interest expense, net was $20.1 million in the nine months ended September 30, 2020, compared to $29.5 million in the nine months ended September 30, 2019. Interest expense includes the interest cost component of the net periodic benefit cost of the Company's pension and post retirement benefits of $3.0 million in the nine months ended September 30, 2020 and $4.0 million in the nine months ended September 30, 2019. The decrease in interest expense net in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 is primarily due to the decrease in interest expense in the second and third quarters of 2020, for the reasons described above.

The unrealized gain on embedded conversion option of $2.0 million in the nine months ended September 30, 2020 is the result of the mark-to-market adjustment associated with the bifurcated embedded derivative liability of the Company's 3.00% / 5.00% Convertible Notes. As of June 30, 2020, the conversion option qualifies for equity classification and the bifurcated derivative liability will no longer need to be accounted for as a separate derivative on a prospective basis from the date of reassessment. Any remaining debt discount that arose at the date of debt issuance from the original bifurcation will continue to be amortized through interest expense.

Other income, net was $0.3 million in the three months ended September 30, 2020, compared to $0.7 million in the three months ended September 30, 2019. Included in other income, net in the three months ended September 30, 2020 and the three months ended September 30, 2019 was net pension benefit of $1.7 million and $1.5 million, respectively. The remaining other income, net for the comparative periods is the result of foreign currency transaction gains and losses. The Company recorded a net foreign currency loss of $1.3 million in the three months ended September 30, 2020, of which $1.5 million was attributable to unrealized losses on foreign currency transactions, partially offset by a $0.2 million unrealized gain on intercompany loan, compared to a net foreign currency loss of $0.8 million in the three months ended September 30, 2019, $0.3 million of which was attributable to unrealized gains on foreign currency transactions and $0.5 million to an unrealized gain on intercompany loan.

Table of Contents

Other income, net was $2.2 million in the nine months ended September 30, 2020, compared to other income, net of $4.8 million in the nine months ended September 30, 2019. Included in other income, net in the nine months ended September 30, 2020 and the nine months ended September 30, 2019 was net pension benefit of $5.0 million and $4.6 million, respectively. The remaining other income, net for the comparative periods is the result of foreign currency transaction gains and losses. The Company recorded a net foreign currency loss of $2.6 million in the nine months ended September 30, 2020, of which $1.9 million is attributable to unrealized losses on foreign currency transactions and $0.7 million is an unrealized loss on intercompany loan, compared to a foreign currency gain of $0.2 million in the nine months ended September 30, 2019, of which $0.4 was attributable to an unrealized gain on intercompany loan, partially offset by a $0.2 million unrealized loss on foreign currency transactions.

Loss before income taxes was $15.3 million in the three months ended September 30, 2020, compared to $13.3 million in the three months ended September 30, 2019. The decrease in the loss before income taxes in the three months ended September 30, 2020 compared to the same period in the prior year was primarily due to a $5.1 million decrease in interest expense, partially offset by an increase in the Company's operating loss in the three months ended September 30, 2020 and the larger unfavorable impact of foreign currency in the three months ended September 30, 2020, compared to the same period last year.

Loss before income taxes of $33.0 million in the nine months ended September 30, 2020 was virtually flat compared to the nine months ended September 30, 2019 as the increase in the operating loss in the nine months ended September 30, 2020 compared to the same period in the prior year was offset by a decrease in interest expense. Further, the decrease in other income, net, which was primarily due to the net unfavorable impact of foreign currency in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, was offset by the impact of the unrealized gain on the embedded debt conversion derivative liability recognized in the second quarter of 2020.

The Company recorded an income tax benefit of $0.6 million in the three months ended September 30, 2020, compared to an income tax benefit of $1.1 million in the three months ended September 30, 2019 and income tax benefit of $3.2 million in the nine months ended September 30, 2020, compared to an income tax benefit of $1.5 million in the nine months ended September 30, 2019. The Company’s effective tax rate is expressed as income tax expense as a percentage of loss before income taxes. The effective tax rate in the three months ended September 30, 2020 was 3.7% as compared to 8.1% in the three months ended September 30, 2019 and 9.6% in the nine months ended September 30, 2020 as compared to 4.9% in the nine months ended September 30, 2019. The change in the effective tax rate between periods resulted from changes in the geographic mix and timing of income or losses, the inclusion of foreign earnings under Internal Revenue Code ("IRC") Section 951A, the impact of the foreign income tax rate differential and, for the nine month period, the increase in the Company's net operating loss carrybacks due to the CARES Act, which was recognized in the nine months ended September 30, 2020.

Net loss was $14.7 million in the three months ended September 30, 2020, compared to $12.2 million in the three months ended September 30, 2019, and $29.8 million in the nine months ended September 30, 2020, compared to $28.5 million in the nine months ended September 30, 2019. Net loss in both the three and nine months ended September 30, 2020 includes a non-cash goodwill impairment charge of $2.7 million.

Liquidity and Capital Resources

Liquidity

Cash and cash equivalents increased (decreased) as follows:

The Company’s principal sources of liquidity are cash provided by operations and proceeds from borrowings under its revolving credit facilities. Given the economic uncertainty and disruptions resulting from the COVID-19 pandemic, the Company will continue to focus on maintaining liquidity to fund its normal operations and appropriately aligning its working capital with the changing economic conditions. In the second and third quarters of 2020, the average

Table of Contents

receivable days outstanding increased from levels in previous quarters, which the Company believes reflects some slowing in payments from customers due to the financial uncertainties resulting from the COVID-19 pandemic. The Company has fewer accounts receivables as of September 30, 2020 as a result of the decrease in demand resulting from the COVID-19 pandemic, which has decreased its borrowing base collateral attributable to accounts receivable under its revolving credit facility and, in the near term, could result in less cash provided by operations. Further decreases in the Company's accounts receivable could result in further reductions in its borrowing base collateral and therefore, the maximum amount it could borrow under its revolving credit facility could decrease accordingly. The decrease in demand has also resulted in a significant increase in average days sales in inventory in the third quarter compared to the previous quarter. The Company is focused on maintaining liquidity by purchasing a sufficient level of inventory to meet customer demand while not carrying excess inventory and lowering overall stock levels throughout the business. However, if the Company is unable to sufficiently manage its inventory levels and it begins to carry excess inventory, its liquidity could be unfavorably impacted. Conversely, a decrease in the Company's inventory could result in a reduction in its borrowing base collateral attributable to inventory and therefore, the maximum amount it could borrow under its revolving credit facility could decrease accordingly.

The ongoing duration and severity of the COVID-19 pandemic could have a significant unfavorable impact on the Company's suppliers' ability to deliver products and services and its customers' ability to purchase goods and services and pay their accounts receivable timely, if at all, which could have a significant adverse effect on the Company's operations, financial condition and liquidity. With the benefit of the various government-sponsored support programs such as tax deferrals, employment-related subsidies, government-backed loans and other government relief available in the U.S. and in other countries in which it operates, including the PPP Loan received in April 2020 and the France Term Loan received in June 2020, coupled with temporary and long-term cost-cutting initiatives implemented by the Company, the Company expects it will be able to maintain adequate liquidity and working capital to continue its normal operations over the next 12 months (see Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations - Impact of Coronavirus (COVID-19) Pandemic). However, given the current uncertain economic conditions, there can be no assurance that the Company will be able to achieve its strategic initiatives or obtain additional funding on favorable terms in the future, which could have a significant adverse effect on its operations, financial condition and liquidity.

Specific components of the change in working capital (defined as current assets less current liabilities), are highlighted below:

•A decrease in accounts receivable at September 30, 2020 compared to December 31, 2019 resulted in a cash flow source of $27.9 million in the nine months ended September 30, 2020, compared to a cash flow use of $8.4 million in the nine months ended September 30, 2019. Average receivable days outstanding was 58.3 days in the nine months ended September 30, 2020 compared to 55.4 days for the nine months ended September 30, 2019, which, the Company believes, reflects some slowing in payments from customers due to the financial uncertainties resulting from the COVID-19 pandemic. Although the Company expects slowness of payments from customers to continue, the Company considered the economic impact of the COVID-19 pandemic on the collectability of customer accounts receivable and determined that no specific additional allowance for doubtful accounts was required as of September 30, 2020. The full impact of the COVID-19 pandemic is unknown and rapidly evolving. The Company will continue to analyze any financial and commercial impacts of the COVID-19 pandemic, including any adverse impact the COVID-19 pandemic may have on the collectability of customer accounts receivable as well as the impact the level of accounts receivable may have on its borrowing capacity under the ABL Credit Agreement.

•Lower inventory levels at September 30, 2020 compared to December 31, 2019 resulted in a cash flow source of $4.7 million in the nine months ended September 30, 2020 compared to lower inventory levels at September 30, 2019 compared to December 31, 2018, which resulted in a cash flow source of $10.0 million in the nine months ended September 30, 2019. Average days sales in inventory was 172.0 days for the nine months ended September 30, 2020 compared to 133.4 days for the nine months ended September 30, 2019. The increase in average days sales in inventory is primarily due to the impact of the COVID-19 pandemic, which caused a significant decrease in sales volume beginning in March 2020. As the Company expects the markets to remain soft due to the impacts of the COVID-19 pandemic, it will continue to focus on managing inventory levels, primarily by reducing aged inventories, lowering overall stock levels throughout the business and the real-time facilitation of its branches in selling higher-priced inventory. The Company will continue to monitor the impact its inventory levels may have on its borrowing capacity under the ABL Credit Agreement.

•A decrease in total accounts payable and accrued and other current liabilities compared to December 31, 2019 resulted in a $1.9 million cash flow use in the nine months ended September 30, 2020 compared to a cash flow source of $1.6 million in the nine months ended September 30, 2019. Accounts payable days outstanding was 56.6 days for the nine months ended September 30, 2020 compared to 41.7 days for the same period last year. The improving financial condition of the Company prior to the impact of the COVID-19 pandemic, particularly the recent completion of the Exchange Offer (defined below), had resulted in improved credit terms with certain of its suppliers, including an extension of net payment dates and/or credit limits. Additionally, as the Company continues to align its cash flows in response to the economic impacts and uncertainties caused by the COVID-19 pandemic, it expects some variability in the timing of payments to vendors to continue.

Working capital and the balances of its significant components are as follows:


	As of
(Dollar amounts in millions)	September 30, 2020		December 31, 2019		Working Capital Increase (Decrease)
Working capital	$	160.2	$	173.7	$	(13.5)
Cash and cash equivalents	24.2		6.4		17.8

Operating lease liabilities	6.5		6.5		—

Approximately $12.7 million of the Company’s consolidated cash and cash equivalents balance of $24.2 million at September 30, 2020 resided in the United States.

The decrease in net cash used in investing activities to $2.3 million during the nine months ended September 30, 2020 from $3.1 million during the nine months ended September 30, 2019 is due to a decrease in cash paid for capital expenditures, primarily purchases of warehouse equipment. The Company expects capital expenditures to be approximately $3.0 million for the full-year 2020.

During the nine months ended September 30, 2020, net cash provided by financing activities of $0.1 million was attributable to net proceeds from long term borrowings made by the Company, which were partially offset by net repayments of short-term borrowings under the Company's foreign line of credit in France and payments of debt restructuring costs. In the nine months ended September 30, 2020, the Company entered into two new long-term debt agreements (PPP Loan and France Term Loan, discussed below), the proceeds of which were partially offset by net repayments under its revolving credit facilities. During the nine months ended September 30, 2019, the net cash used in financing activities of $2.7 million was primarily attributable to net principal repayments made by the Company on its revolving credit facility, as well as net repayments of short-term borrowings under the Company's foreign lines of credit.

Capital Resources

The Company's various credit arrangements are with well-established, global lenders. The Company does not expect the COVID-19 pandemic will have a significant impact on the ability of these lenders to continue to lend cash to the Company pursuant to the credit arrangements that the Company has with these lenders.

On August 31, 2017, the Company entered into the Revolving Credit and Security Agreement with PNC Bank, National Association ("PNC") as lender and as administrative and collateral agent (the “Agent”), and other lenders party thereto (the "Original ABL Credit Agreement"). The Original ABL Credit Agreement provided for a $125.0 million senior secured, revolving credit facility (the "Revolving A Credit Facility"), under which the Company and four of its subsidiaries each are borrowers (collectively, in such capacity, the “Borrowers”). The obligations of the Borrowers have been guaranteed by the subsidiaries of the Company named therein as guarantors. On June 1, 2018, the Company entered into an Amendment No. 1 to ABL Credit Agreement (the “Credit Agreement Amendment No. 1”) by and among the Company, the Borrowers and guarantors party thereto and the Agent and the other lenders party thereto, which amended the Original ABL Credit Agreement to provide for additional borrowing capacity. On March 27, 2020, the Company entered into an Amendment No. 2 to the Original ABL Credit Agreement (the "Credit Agreement Amendment No. 2) by and among the Company, the Borrowers and guarantors party thereto and the Agent and other lenders party thereto, which amended the Original ABL Credit Agreement (as amended by

Table of Contents

the Credit Agreement Amendment No. 1 and Credit Agreement Amendment No. 2, the "ABL Credit Agreement") to permit the Exchange Offer (defined below) to proceed. The ABL Credit Agreement provides for an additional $25.0 million last out Revolving B Credit Facility (the "Revolving B Credit Facility" and together with the Revolving A Credit Facility, the "Credit Facility") made available in part by way of a participation in the Revolving B Credit Facility by certain of the Company’s stockholders. Borrowings under the Credit Facility will mature on February 28, 2022.

The Company may prepay its obligations under the ABL Credit Agreement at any time without premium or penalty, and must apply the net proceeds of material sales of collateral in prepayment of such obligations. Payments made must be applied to the Company's obligations under the Revolving A Credit Facility, if any, prior to its obligations under the Revolving B Credit Facility. In connection with an early termination or permanent reduction of the Revolving A Credit Facility prior to March 27, 2021, a 0.50% fee shall be due and, for the period from March 28, 2021 through September 27, 2021, a 0.25% fee shall be due, in each case in the amount of such commitment reduction, subject to reduction as set forth in the ABL Credit Agreement. Indebtedness for borrowings under the ABL Credit Agreement is subject to acceleration upon the occurrence of specified defaults or events of default, including (i) failure to pay principal or interest, (ii) the inaccuracy of any representation or warranty of a loan party, (iii) failure by a loan party to perform certain covenants, (iv) defaults under indebtedness owed to third parties, (v) certain liability producing events relating to ERISA, (vi) the invalidity or impairment of the Agent’s lien on its collateral or of any applicable guarantee, and certain adverse bankruptcy-related and (vii) certain adverse bankruptcy-related and other events.

Interest on indebtedness under the Revolving A Credit Facility accrues at a variable rate based on a grid with the highest interest rate being the applicable LIBOR-based rate plus a margin of 3.0%, as set forth in the ABL Credit Agreement. Interest on indebtedness under the Revolving B Credit Facility accrues at a rate of 12.0% per annum, which will be paid-in-kind unless the Company elects to pay such interest in cash and the Revolving B payment conditions specified in the ABL Credit Agreement are satisfied. Additionally, the Company must pay a monthly facility fee equal to the product of (i) 0.25% per annum (or, if the average daily revolving facility usage is less than 50% of the maximum revolving advance amount of the Credit Facility, 0.375% per annum) multiplied by (ii) the amount by which the maximum advance amount of the Credit Facility exceeds such average daily Credit Facility usage for such month.

Under the ABL Credit Agreement, the maximum borrowing capacity of the Revolving A Credit Facility is based on the Company's borrowing base calculation. As of September 30, 2020, the weighted average advance rates used in the borrowing base calculation are 85.0% on eligible accounts receivable and 69.4% on eligible inventory.

The Company's ABL Credit Agreement contains certain covenants and restrictions customary to an asset-based revolving loan. Pursuant to the terms of the ABL Credit Agreement, the PPP Loan and the France Term Loan shall be excluded for all purposes from any covenant calculations.

The Company's ABL Credit Agreement contains a springing financial maintenance covenant requiring the Company to maintain a Fixed Charge Coverage Ratio of 1.0 to 1.0 in any Covenant Testing Period (as defined in the ABL Credit Agreement) when the Company's cash liquidity (as defined in the ABL Credit Agreement) is less than $12.5 million for five consecutive days. The Company was not in a Covenant Testing Period as of and for the three and nine months ended September 30, 2020.

Additionally, upon the occurrence and during the continuation of an event of default or upon the failure of the Company to maintain cash liquidity (as defined in the ABL Credit Agreement, inclusive of certain cash balances and the additional unrestricted borrowing capacity shown below) in excess of $12.5 million, the lender has the right to take full dominion of the Company’s cash collections and apply these proceeds to outstanding loans under the ABL Credit Agreement (“Cash Dominion”). A prolonged economic downturn due to the COVID-19 pandemic could result in the Company's cash liquidity decreasing to a level that would cause Cash Dominion to occur and/or the Company to enter into a Covenant Testing Period. The extent to which the COVID-19 pandemic will impact the Company's

Table of Contents

liquidity is currently unknown. Based on the Company's current cash projections, taking into consideration the benefit of the various government-sponsored support programs such as tax deferrals, employment-related subsidies, government-backed loans and other government relief available in the U.S. and in other countries in which it operates, including the PPP Loan received in April 2020, coupled with temporary and long-term cost-cutting initiatives implemented by the Company, it does not anticipate that Cash Dominion will occur, or that it will be in a Covenant Testing Period during the next 12 months.

On April 28, 2020, the Company entered into the PPP Loan, which provides additional cash to be used for payroll costs, interest on mortgages, rent and utilities. The Company intends to apply for forgiveness of the full amount of the PPP Loan in accordance with the terms of the PPP and the CARES Act; however, the Company cannot assure at this time that the PPP Loan will be fully forgiven. On June 24, 2020, the Company's French subsidiary entered into the France Term Loan, which is fully guaranteed by the French government, and provides additional capital to support the Company’s ongoing operations in France.

Considerable uncertainty exists with regards to the ultimate duration and severity of the COVID-19 pandemic as well as the full extent of the impact that the COVID-19 pandemic will have on the Company's business, operations and financial condition. However, with the benefit of the various government-sponsored support programs such as tax deferrals, employment-related subsidies, government-backed loans and other government relief available in the U.S. and in other countries in which it operates, including the PPP Loan received in April 2020 and the France Term Loan received in June 2020, coupled with the temporary and long-term cost-cutting initiatives implemented by the Company, the Company believes that its existing cash balances, together with cash generated from operations and proceeds from its various revolving credit facilities, will be sufficient to fund its normal business operations and service its debt over the next twelve months from the issuance of this report.

The Company's ability to borrow funds is dependent on its ability to maintain an adequate borrowing base. Accordingly, if the Company does not generate sufficient cash flow from operations to fund its working capital needs and planned capital expenditures, and its availability is depleted, it may need to take further actions, such as reducing or delaying capital investments, strategic investments or other actions. A prolonged economic downturn due to the COVID-19 pandemic could unfavorably impact the Company's ability to fund its working capital needs through operating cash flows, which could result in a reduction in its borrowing base. Although the extent to which the COVID-19 pandemic will impact the Company's operating cash flows and borrowing base is currently unknown, the Company anticipates it will be able to maintain an adequate borrowing base to support ongoing availability under its ABL Credit Agreement.

Additional unrestricted borrowing capacity under the Revolving A Credit Facility as of September 30, 2020 was as follows (in millions):


Maximum borrowing capacity	$	125.0
Collateral reserves	(32.7)
Letters of credit and other reserves	(2.4)

Current maximum borrowing capacity	89.9
Current borrowings	(89.2)
Additional unrestricted borrowing capacity(a)	$	0.7
(a) Subject to the cash dominion threshold noted above

On November 16, 2020, the Company announced it had reached an agreement in principle with its first lien lender, PNC, and certain of its stockholders to provide for a new $8.0 million term loan from such stockholders, subordinated only to the Revolving A Credit Facility. As part of this agreement in principle, the Company and PNC also agreed to extend the maturity date of the Revolving A Credit Facility to February 28, 2023 and to amend certain aspects of the facility to lower the minimum (on hand) liquidity requirement that the Company must maintain by $3.8 million under the terms of the Revolving A Credit Facility. Refer to Note 13 - Subsequent Events in the notes to the condensed consolidated financial statements for further details.

On March 27, 2020, the Company completed the Exchange Offer to issue its the 3.00%/5.00% Convertible Notes and shares of its common stock in exchange for its 5.00%/7.00% Convertible Notes, including any accrued and unpaid interest on the 5.00%/7.00% Convertible Notes as of the date in which the Exchange Offer was completed. Pursuant to the terms of the Exchange Offer, $190.2 million in aggregate principal amount of the 5.00%/7.00% Convertible Notes were tendered and accepted and in exchange, the Company issued $95.1 million in aggregate principal amount of its 3.00%/5.00% Convertible Notes and 70,261 shares of its common stock. An aggregate

Table of Contents

principal amount of 5.00%/7.00% Convertible Notes in the amount of $3.7 million were not tendered and remained outstanding at the date of Exchange Offer. As a result of the Exchange Offer, the Company reduced the aggregate principal amount of its long-term debt by $94.5 million and expects to reduce its annual interest expense by over $10.0 million.

The 3.00%/5.00% Convertible Notes were issued pursuant to an indenture (the “3.00%/5.00% Convertible Notes Indenture”), which the Company and the Guarantors (defined below) entered into with Wilmington Savings Fund Society, FSB, as trustee and collateral agent ("Indenture Agent"), on March 27, 2020. The 3.00%/5.00% Convertible Notes are, secured by a lien on all or substantially all of the assets of the Company, its domestic subsidiaries and certain of its foreign subsidiaries, which lien the Indenture Agent has agreed will be junior to the lien of the Agent under the ABL Credit Agreement.

The 3.00%/5.00% Convertible Notes have substantially the same terms that the 5.00%/7.00% Convertible Notes had prior to the completion of the Exchange Offer, except for the following primary differences: (i) the 3.00%/5.00% Convertible Notes are not exempt from the registration requirements of the Securities Act and have the benefit of registration rights to the holders of the 3.00%/5.00% Convertible Notes, (ii) the interest on the 3.00%/5.00% Convertible Notes accrues at the rate of 3.00% per annum if paid in cash and at the rate of 5.00% per annum if paid in kind, compared to interest on the 5.00%/7.00% Convertible Notes, which accrues at the rate of 5.00% per annum if paid in cash and at the rate of 7.00% per annum if paid in kind, and (iii) the 3.00%/5.00% Convertible Notes have a maturity date of August 31, 2024, compared to the 5.00%/7.00% Convertible Notes, which have a maturity date of August 31, 2022.

with a Fundamental Change (as defined in the Supplemental Indenture) is substantially the same as under the 3.00%/5.00% Convertible Notes Indenture, other than the applicable conversion price.

As discussed previously, the 3.00%/5.00% Convertible Notes are convertible into common stock at the option of the holder. The Company determined that the conversion option is not clearly and closely related to the economic characteristics of the 3.00%/5.00% Convertible Notes, nor does the conversion option meet the own equity scope exception as the Company does not currently have sufficient authorized and unissued common stock shares to satisfy the maximum number of common stock shares that could be required to be issued upon conversion. The initial value allocated to the derivative liability was $38,962, with a corresponding reduction in the carrying value of the 3.00%/5.00% Convertible Notes.

As a result of the Company's filing articles of amendment to increase the number of shares of common stock authorized, the number of the Company's common stock shares available for issuance upon conversion of the 3.00%/5.00% Convertible Notes is sufficient to allow the conversion option to be share-settled in full. The Company has concluded that as of June 30, 2020 the conversion option qualifies for equity classification and the bifurcated derivative liability will no longer need to be accounted for as a separate derivative on a prospective basis from the date of reassessment. As of June 30, 2020, the fair value of the conversion option of $36,952, was classified to equity as additional paid-in capital. There was no tax impact of the reclassification of the conversion option to equity. Any remaining debt discount that arose at the date of debt issuance from the original bifurcation will continue to be amortized through interest expense.

The terms of the 3.00%/5.00% Convertible Notes contain numerous covenants imposing financial and operating restrictions on the Company's business. These covenants place restrictions on the Company’s ability and the ability of its subsidiaries to, among other things, pay dividends, redeem stock or make other distributions or restricted payments; incur indebtedness or issue certain stock; make certain investments; create liens; agree to certain payment restrictions affecting certain subsidiaries; sell or otherwise transfer or dispose assets; enter into transactions with affiliates; and enter into sale and leaseback transactions.

Indebtedness for borrowings under the 3.00%/5.00% Convertible Notes Indenture and the Supplemental Indenture is subject to acceleration upon the occurrence of specified defaults or events of default as set forth under each such indenture, including failure to pay principal or interest, the inaccuracy of any representation or warranty of any obligor, failure by an obligor to perform certain covenants, the invalidity or impairment of the Agent’s lien on its collateral under the 3.00%/5.00% Convertible Notes Indenture, the invalidity or impairment of any applicable guarantee, and certain adverse bankruptcy-related and other events. Although the full extent that the COVID-19 pandemic will have on the Company's business, operations and financial condition is currently unknown, it does not anticipate that any specified defaults or events of default as set forth in the indenture will occur during the next 12 months.

holders representing a majority in aggregate principal amount of the 3.00%/5.00% Convertible Notes, and may in effect release collateral from the liens securing the 3.00%/5.00% Convertible Notes with the consent of holders representing 66-2/3% in aggregate principal amount of the 3.00%/5.00% Convertible Notes.

Interest on the 3.00%/5.00% Convertible Notes accrues at the rate of 3.00% per annum if paid in cash and at the rate of 5.00% per annum if paid in kind, payable quarterly. Interest on the 5.00%/7.00% Convertible Notes continues to accrue at the rate of 5.00% per annum if paid in cash and at the rate of 7.00% per annum if paid in kind, payable quarterly. Pursuant to the terms of both the 3.00%/5.00% Convertible Notes Indenture and the Supplemental Indenture, the Company is currently paying interest on both the 3.00%/5.00% Convertible Notes and the 5.00%/7.00% Convertible Notes in kind.

Summarized Parent and Guarantor Financial Information

As discussed above, the 3.00%/5.00% Convertible Notes issued by A.M. Castle and Co. (the "Parent") are unconditionally guaranteed on a joint and several basis by all current and future domestic subsidiaries of the Parent (other than those designated as unrestricted subsidiaries) and the parent’s subsidiaries in Canada and Mexico (collectively, the “Guarantors”). Each guarantor is 100% owned by the Parent.

The guarantees of the Guarantors are subject to release in limited circumstances, only upon the occurrence of certain customary conditions. There are no significant restrictions on the ability of the parent company or any guarantor to obtain funds from its subsidiaries by dividend or loan.

On March 31, 2020, the Company early adopted the guidance of the SEC Final Rule Release No. 33-10762, "Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant's Securities" (the "final rule") and has elected to present the summarized financial information of Parent and Guarantors (together, the "Obligors") as of and for the six months ended September 30, 2020 and as of and for the year ended December 31, 2019 (see Note 2 - New Accounting Standards, to the notes to the condensed consolidated financial statements for further information on the final rule).

The summarized financial information of the Obligors after elimination of (i) intercompany transactions and balances among the Parent and the Guarantors and (ii) equity in earnings from and investments in any subsidiary that is a Non-Guarantor follows:


	Obligors
(in millions)	As of and for the Nine Months Ended September 30, 2020		As of and for the Year Ended December 31, 2019

Included in non-current liabilities are $7.5 million and $8.6 million of non-current intercompany payables due to the Non-Guarantors from the Obligors as of September 30, 2020 and December 31, 2019, respectively.

Other Credit Facilities

In July 2017, the Company's French subsidiary entered into a local credit facility under which it may borrow against 100% of the eligible accounts receivable factored, with recourse, up to 6.5 million Euros, subject to factoring fees and floating Euribor or LIBOR interest rates, plus a 1.0% margin. The French subsidiary utilizes the local credit facility to support its operating cash needs. As of September 30, 2020, the French subsidiary had no borrowings under the local credit facility and had borrowings under the local credit facility of $2.9 million as of December 31, 2019. The Company records borrowings under the local credit facility as short-term borrowings at the Condensed Consolidated Balance Sheets.

Critical Accounting Policies

The preparation of our financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Part II, Item 7 of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019 includes a summary of the critical accounting policies we believe are the most important to aid in understanding our financial results. There have been no changes to those critical accounting policies that have had a material impact on our reported amounts of assets, liabilities, revenues or expenses during the nine months ended September 30, 2020.

Our business and operations, and the operations of our suppliers and customers, have been, and for an indefinite period of time may continue to be, adversely affected by the recent novel coronavirus (or COVID-19) pandemic.

We may face risks related to the ongoing outbreak of the Novel Coronavirus Disease 2019 (COVID-19), which has been declared a “pandemic” by the World Health Organization and a national public health emergency by governments throughout the world as the disease has spread across the globe and is substantially and materially impacting worldwide economic activity. The full impact of COVID-19 and the associated pandemic is unknown and rapidly evolving. Health epidemics or outbreaks of communicable diseases such as COVID-19 could result in widespread or localized health crises that could adversely affect general commercial activity and the economies and financial markets of many countries or localities in which the Company operates, sells, or purchases good and services. A public health epidemic, including COVID-19, poses the risk that we or our employees, contractors, suppliers, customers, transportation providers, and other business partners may from time to time be prevented or impaired from conducting ordinary course business activities for indefinite periods of time, either at specific branches or on a broader scale, including due to shutdowns necessitated for the health and well-being of our employees, the employees of our business partners, or shutdowns that may be requested or mandated by governmental authorities. Directives to “de-densify” worksites, “Shelter in Place,” “Safe at Home,” quarantine or similar orders or mandates that restrict workforce and/or require closures of “non-essential” businesses have been implemented by government authorities to one degree or another starting with China in January 2020 and quickly spreading in the following months through Europe, North America and most locations throughout the world. Such orders or mandates have been lifted in many geographies, but there is a continuing threat that such measures may again be required as the spread of the disease has also accelerated in certain geographies. Although the Company has already been adversely impacted by the COVID-19 pandemic, the situation is very fluid and subject to rapid change; the full extent of the impact that the COVID-19 pandemic may have on the Company's business, operations and financial condition is currently unknown.

While we have fortunately had only a small number of reported positive cases of COVID-19 among our workforce, and while our branches have as a whole generally remained operational at varying levels of volume, there can be no assurances that from time to time we will not have to close any branch or multiple branches for indefinite periods of time due to concerns over the health and well-being of our employees, due to further developments in government directives or due to continued drop in demand from our customers or disruptions from our suppliers. While we have implemented policies and practices to protect our employees at each of our locations, including sanitizing and cleaning protocols, requiring face coverings and other personal protective equipment, social distancing and other behavioral best practices, remote work arrangements, staggered and spaced work shifts, separating workspaces by distance and/or physical barriers, and suspending non-essential employee travel and visitors to our locations throughout the world, there can be no assurances that these efforts will be successful to

prevent a contamination from impacting or potentially closing any of our branches or corporate offices for a time. While each of our operations has prepared and regularly updates customized business continuity and return to work plans to address COVID-19 concerns, in an effort to ensure that we are protecting our employees, continuing to operate our business and service our customers’ needs, and mitigating the potential impacts of COVID-19 or other similar epidemics, there is no guarantee that such plans will anticipate or fully mitigate the various impacts the pandemic, much of which is still entirely uncertain. While it is not possible at this time to estimate the scope and severity of the impact that COVID-19 could have on our branches, the continued spread of COVID-19, the measures taken by the governments of countries affected, actions taken to protect employees, actions taken to continue operations, and the impact of the pandemic on various business activities in affected countries could adversely affect our financial condition, results of operations and cash flows.

In April 2020, we applied for and received a $10.0 million PPP Loan (see Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations - Impact of Coronavirus (COVID-19) Pandemic). After taking into account, among other things, the disruptions to our business activities caused by the COVID-19 pandemic, our completed Exchange Offer, available, committed primary sources of liquidity, and our lack of access to alternative sources of liquidity, we believed and certified that economic conditions at that time made this loan request necessary and appropriate to support our ongoing U.S. operations and mitigate potentially significant detriment to our business. Recipients of loans in excess of $2.0 million will be audited and, despite our good-faith belief that given our circumstances we then satisfied and continue to satisfy all eligible requirements for the PPP Loan as well as all conditions for loan forgiveness, the federal government may disagree and determine that we were ineligible to have applied for and received the PPP Loan and/or ineligible for loan forgiveness either in full and/or in part. In such event, we may be required to repay the PPP Loan in its entirety and could be subject to additional penalties, which could have a material adverse effect on our liquidity and financial condition.

While we have and continue to pursue government relief programs in addition to the PPP loan and the France Term Loan (including tax deferrals, subsidies, loans, etc.) and have and continue to implement a number of temporary and long-term cost-cutting initiatives to align our operations to current customer demand as well as be prepared for any market recovery once this pandemic has passed, including staff reductions, reduction in employee hours and/or salaries, furloughs, temporary layoffs, or a combination of these actions, at each of our locations there can be no assurances that such actions will be sufficient to stave off the economic impacts of the pandemic or that further such actions will not be warranted. We have seen a significant reduction in customer forecasts and orders as a result of the pandemic and there can be no assurances that we will not see further degradation in customer business in the short-term and it is uncertain how quickly customer forecasts and business will improve following this pandemic.

Our principal sources of liquidity are cash provided by operations and proceeds from borrowings under its revolving credit facilities. Starting in the second quarter of 2020, and continuing into the third quarter of 2020, the average receivable days outstanding increased from levels in previous quarters, which the Company believes reflects some slowing in payments from customers due to the financial uncertainties resulting from the COVID-19 pandemic. We also have fewer accounts receivables as of September 30, 2020 (as compared to the previous quarters) as a result of the decrease in demand resulting from the COVID-19 pandemic, which has decreased our borrowing base collateral attributable to accounts receivable under our revolving credit facility and, in the near term, could result in less cash provided by operations. Further decreases in our accounts receivable could result in further reductions in our borrowing base collateral and therefore, the maximum amount we could borrow under our revolving credit facility could decrease accordingly. The decrease in demand has also resulted in an increase in inventory and average days sales in inventory in the second and third quarters compared to previous quarters. We are focused on maintaining liquidity by purchasing a sufficient level of inventory to meet customer demand while not carrying excess inventory and lowering overall stock levels throughout the business. However, if we are unable to sufficiently manage our inventory levels and we begin to carry excess inventory, our liquidity could be unfavorably impacted. Conversely, a decrease in our inventory could result in a reduction in our borrowing base collateral attributable to inventory and therefore, the maximum amount we could borrow under our revolving credit facility could decrease accordingly.

The full extent to which COVID-19 impacts our business both in the short-term and long-term will depend on the continuing severity, location and duration of the spread of COVID-19 as well as resurgent outbreaks of COVID-19 which could result as communities reopen. The extent of the impact will further depend on, among other things, the rate, pace, and effectiveness of the actions undertaken by local and world governments and health officials to contain the virus or treat its effects, the nature of government public health guidelines and the public’s adherence to those guidelines, the impact of government economic relief on the US economy, unemployment levels, the success of businesses reopening, the timing for proven treatments and vaccines for COVID-19, consumer confidence and

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of PresentationThe Condensed Consolidated Financial Statements of A.M. Castle & Co. and its consolidated subsidiaries (collectively, the "Company") included herein and the notes thereto have been prepared by the Company, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), and accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet at December 31, 2019 is derived from the audited financial statements at that date. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. In the opinion of the Company's management, the unaudited statements included herein contain all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of financial results for the interim period. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The operating results for the three and nine months ended September 30, 2020, as reported herein, may not necessarily be indicative of the Company’s operating results for the full year.

New Accounting Standards	9 Months Ended
New Accounting Standards	Sep. 30, 2020
Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards Standards Updates Adopted In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU No. 2018-13 amends Fair Value Measurement (Topic 820) to add, remove, and modify fair value measurement disclosure requirements. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 820's disclosure requirements under the aforementioned FASB disclosure framework project. The Company adopted the disclosure requirements of ASU No. 2018-13 in the first quarter of 2020. The Company determined the adoption of the disclosure requirements had no impact on its fair value disclosures herein. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 amends ASC 740 to simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations and interim calculations, and adding guidance to reduce complexity in the accounting standard under the FASB’s simplification initiative. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020. Upon adoption, the amendments in ASU 2019-12 should be applied on a prospective basis to all periods presented. Early adoption is permitted. The Company adopted the new guidance under ASU 2019-12 in the first quarter of 2020 and removed the exception for intraperiod allocations from its interim period tax provision calculation, accordingly. On March 2, 2020, the SEC issued Final Rule Release No. 33-10762, "Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities" (the “final rule”). The final rule simplifies the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rules 3-10 and 3-16, which currently require separate financial statements for (1) subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met and (2) affiliates that collateralize registered securities offerings if the affiliates’ securities are a substantial portion of the collateral. Under the final rule, alternative financial disclosures or narrative disclosures (referred to collectively as “Alternative Disclosures”) may be provided in lieu of separate financial statements of the guarantors or affiliates. The amendments in the final rule are generally effective for filings on or after January 4, 2021, with early application permitted. The Company has elected to adopt the amendments of the final rule for the quarter ended March 31, 2020 and accordingly, has elected to present the alternative disclosures of the guarantors of its registered securities in Part I Item 2, Management's Discussion and Analysis, of this Form 10-Q. Standards Updates Issued Not Yet Effective In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 adds a current expected credit loss (“CECL”) impairment model to U.S. GAAP that is based on expected losses rather than incurred losses. Modified retrospective adoption is required with any cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. ASU 2016-13 is effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within the year of adoption. Early adoption is permitted. The Company will adopt the guidance and disclosure requirements of ASU 2016-13 in fiscal year 2023. In August 2018, the FASB issued ASU No. 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans - General (Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plan.” ASU No. 2018-14 amends Compensation - Retirement Benefits (Topic 715) to add or remove certain disclosure requirements related to defined benefit pension and other postretirement plans. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 715's disclosure requirements under the FASB’s disclosure framework project. ASU No. 2018-14 is effective for public entities for fiscal years beginning after December 15, 2020. ASU No. 2018-14 does not impact the interim disclosure requirements of Topic 715. Early adoption is permitted. The Company will adopt the disclosure requirements of this new guidance in fiscal year 2021. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The purpose of ASU 2020-04 is to provide optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting. In response to concerns about structural risks of interbank offered rates, and, in particular, the risk of cessation of the London Interbank Offered Rate (LIBOR), reference rate reform refers to a global initiative to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a topic or an industry subtopic, the amendments in ASU 2020-04 must be applied prospectively for all eligible contract modifications for that topic or industry subtopic. The Company is currently assessing the accounting and financial impact of reference rate reform and will consider applying the optional guidance of ASU 2020-04 accordingly.

Goodwill and Intangible Asset	Sep. 30, 2020
Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Asset	Goodwill and Intangible Asset As of December 31, 2019, the Company had goodwill with a carrying value of $2,676, none of which was tax deductible. As a result of the COVID-19 pandemic, which has spread across the globe to many countries in which the Company does business and is impacting worldwide economic activity, the Company has determined that the potential impact on its business, including, but not limited to, a potential decrease in revenue, supply chain disruptions and/or facility closures, represented facts and circumstances indicating that it was likely that its goodwill and indefinite lived trade name could be impaired, and performed interim impairment tests. Based on the results of the Company's interim goodwill impairment test performed in the third quarter of 2020, the Company determined its one reporting unit's goodwill was impaired. The Company recorded a non-cash goodwill impairment charge of $2,676 during the three months ended September 30, 2020, reducing the remaining balance of its goodwill to zero as of September 30, 2020. The gross carrying value of the Company's trade name intangible asset, which is not subject to amortization, was $5,500 at both September 30, 2020 and December 31, 2019. Based on the results of the interim impairment tests of the indefinite-lived trade name assets performed in the first, second and third quarters of 2020, the Company determined its one reporting unit's indefinite-lived trade name asset was not impaired as of September 30, 2020. While the Company considered the impact the COVID-19 pandemic may have on its future cash flows when preparing its interim goodwill and intangible asset impairment tests, the full extent of the impact that the COVID-19 pandemic will have on the Company's business, operations and financial condition is currently unknown. The Company will continue to assess its indefinite-lived trade name intangible asset for impairment as events and circumstances change.

Income Taxes	Sep. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items. The Company’s effective tax rate is expressed as income tax benefit as a percentage of loss before income taxes. On March 27, 2020, the U.S. federal government signed into law the CARES Act, to provide economic relief to U.S. companies impacted by the COVID-19 pandemic. Pursuant to the provisions of the CARES Act, the Company filed a carryback claim to utilize its net operating losses from 2019 to offset taxable net income realized in 2018. In the three months ended September 30, 2020, the Company recorded income tax benefit of $572 on a loss before income taxes of $15,316, for an effective tax rate of 3.7%. In the three months ended September 30, 2019, the Company recorded income tax benefit of $1,079 on a loss before income taxes of $13,275, for an effective tax rate of 8.1%. In the nine months ended September 30, 2020, the Company recorded income tax benefit of $3,163 on a loss before income taxes of $33,001, for an effective tax rate of 9.6%. In the nine months ended September 30, 2019, the Company recorded income tax benefit of $1,479 on a loss before income taxes of $29,982, for an effective tax rate of 4.9%. The most significant factors impacting the effective tax rate in the three months ended September 30, 2020 were (i) the recording of the period expense associated with the quasi territorial tax regime called the Global Intangible Low Taxed Income Inclusion (“GILTI”), (ii) the foreign rate differential, and (iii) changes in valuation allowances in the United States and Canada. Also impacting the effective tax rate in the nine months ended September 30, 2020 was the increase in net operating loss carrybacks due to the CARES Act. The Company's U.S. federal corporate income tax rate is 21%.

Commitments and Contingent Liabilities	Sep. 30, 2020
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent LiabilitiesFrom time to time, the Company is party to a variety of legal proceedings, claims, and inquiries, including proceedings or inquiries by governmental authorities, which arise from the operation of its business. These proceedings, claims, and inquiries are incidental to and occur in the normal course of the Company's business affairs. The majority of these proceedings, claims, and inquiries relate to commercial disputes with customers, suppliers, and others; employment and employee benefits-related disputes; product quality disputes with vendors and/or customers; and environmental, health and safety claims. Although the outcome of these proceedings is inherently difficult to predict, management believes that the amount of any judgment, settlement or other outcome of these proceedings, claims and inquiries, after taking into account recorded accruals and the availability and limits of our insurance coverage, will not have a material adverse effect on the Company’s consolidated results of operations, financial condition or cash flows.

Subsequent Events	Sep. 30, 2020
Subsequent Events [Abstract]
Subsequent Event	Subsequent Events (share and cash payment in lieu of fractional share amounts are presented as whole numbers)On October 30, 2020, the Company announced that it will effect a reverse split of the Company’s outstanding shares of common stock (the “Common Stock”), pursuant to Section 2-309(e) of the Maryland General Corporation Law, whereby each 10 shares of Common Stock issued and outstanding as of the effective date of the reverse stock split will be combined into one whole share of Common Stock (the “Reverse Stock Split”). No fractional shares of Common Stock will be issued as a result of the Reverse Stock Split. In lieu of issuing any fractional shares to any stockholder as a result of the Reverse Stock Split, the Company will make, to any stockholder that would otherwise hold a fractional share after giving effect to the Reverse Stock Split, a cash payment in an amount equal to $0.70 multiplied by the number of pre-split shares held by such stockholder with respect to which a fractional share would be issued, which represents a premium of approximately 70% over the 20-day VWAP (volume weighted average price) of the Common Stock on the Best Market tier of the OTC Markets Group, Inc. beginning on October 9, 2020 and ending on October 28, 2020. The Company expects the Reverse Stock Split to be completed in the fourth quarter of 2020 or early in the first quarter of 2021. On November 16, 2020, the Company announced it had reached an agreement in principle with its first lien lender, PNC, and certain of its stockholders to provide for a new $8,000 term loan (the "Revolving B Term Loan") from such stockholders, subordinated only to the Revolving A Credit Facility. The Revolving B Term Loan will accrue at a rate of 15.0% per annum, which will be paid-in-kind unless the Company qualifies and elects to pay such interest in cash. As part of this agreement in principle, the Company and PNC also agreed to extend the maturity date of the Revolving A Credit Facility to February 28, 2023, and to (i) amend certain aspects of the facility to lower the minimum (on-hand) liquidity requirement that the Company must maintain by $3,750 under the terms the Revolving A Credit Facility, and (ii) increase the interest rate applicable to the Revolving Credit A Facility to LIBOR-base rate plus a margin of 4.0%. The agreement in principle is subject to customary conditions to closing, including execution of acceptable documentation and final approval, which the Company expects to occur during the fourth quarter of 2020. The Company expects to pay an amendment fee of 0.20% on the $125,000 borrowing capacity of the amended Revolving A Credit Facility.

New Accounting Standards (Policies)	9 Months Ended
New Accounting Standards (Policies)	Sep. 30, 2020
Accounting Changes and Error Corrections [Abstract]
Standards Updates Adopted and Standards Updates Issued Not Yet Effective	Standards Updates Adopted In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU No. 2018-13 amends Fair Value Measurement (Topic 820) to add, remove, and modify fair value measurement disclosure requirements. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 820's disclosure requirements under the aforementioned FASB disclosure framework project. The Company adopted the disclosure requirements of ASU No. 2018-13 in the first quarter of 2020. The Company determined the adoption of the disclosure requirements had no impact on its fair value disclosures herein. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 amends ASC 740 to simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations and interim calculations, and adding guidance to reduce complexity in the accounting standard under the FASB’s simplification initiative. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020. Upon adoption, the amendments in ASU 2019-12 should be applied on a prospective basis to all periods presented. Early adoption is permitted. The Company adopted the new guidance under ASU 2019-12 in the first quarter of 2020 and removed the exception for intraperiod allocations from its interim period tax provision calculation, accordingly. On March 2, 2020, the SEC issued Final Rule Release No. 33-10762, "Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities" (the “final rule”). The final rule simplifies the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rules 3-10 and 3-16, which currently require separate financial statements for (1) subsidiary issuers and guarantors of registered debt securities unless certain exceptions are met and (2) affiliates that collateralize registered securities offerings if the affiliates’ securities are a substantial portion of the collateral. Under the final rule, alternative financial disclosures or narrative disclosures (referred to collectively as “Alternative Disclosures”) may be provided in lieu of separate financial statements of the guarantors or affiliates. The amendments in the final rule are generally effective for filings on or after January 4, 2021, with early application permitted. The Company has elected to adopt the amendments of the final rule for the quarter ended March 31, 2020 and accordingly, has elected to present the alternative disclosures of the guarantors of its registered securities in Part I Item 2, Management's Discussion and Analysis, of this Form 10-Q. Standards Updates Issued Not Yet Effective In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 adds a current expected credit loss (“CECL”) impairment model to U.S. GAAP that is based on expected losses rather than incurred losses. Modified retrospective adoption is required with any cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. ASU 2016-13 is effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within the year of adoption. Early adoption is permitted. The Company will adopt the guidance and disclosure requirements of ASU 2016-13 in fiscal year 2023. In August 2018, the FASB issued ASU No. 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans - General (Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plan.” ASU No. 2018-14 amends Compensation - Retirement Benefits (Topic 715) to add or remove certain disclosure requirements related to defined benefit pension and other postretirement plans. The ASU’s changes to disclosures aim to improve the effectiveness of Topic 715's disclosure requirements under the FASB’s disclosure framework project. ASU No. 2018-14 is effective for public entities for fiscal years beginning after December 15, 2020. ASU No. 2018-14 does not impact the interim disclosure requirements of Topic 715. Early adoption is permitted. The Company will adopt the disclosure requirements of this new guidance in fiscal year 2021. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The purpose of ASU 2020-04 is to provide optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting. In response to concerns about structural risks of interbank offered rates, and, in particular, the risk of cessation of the London Interbank Offered Rate (LIBOR), reference rate reform refers to a global initiative to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a topic or an industry subtopic, the amendments in ASU 2020-04 must be applied prospectively for all eligible contract modifications for that topic or industry subtopic. The Company is currently assessing the accounting and financial impact of reference rate reform and will consider applying the optional guidance of ASU 2020-04 accordingly.
