ULTRALIFE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands except share and per share amounts)

(Unaudited)

1. BASIS OF PRESENTATION

The accompanying unaudited Consolidated Financial Statements of Ultralife Corporation and its subsidiaries (the “Company” or “Ultralife”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions to Rule 8-03 of Regulation S-X. Accordingly, they do not include all the information and footnotes for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair presentation of the Consolidated Financial Statements have been included. Results for interim periods should not be considered indicative of results to be expected for a full year. Reference should be made to the Consolidated Financial Statements and related notes thereto contained in our Form 10-K for the year ended December 31, 2020.

The December 31, 2020 consolidated balance sheet information referenced herein was derived from audited financial statements but does not include all disclosures required by GAAP.

Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation.

Recently Adopted Accounting Guidance

Effective January 1, 2021, the Company adopted Accounting Standards Update (“ASU”) 2019-12, “Simplifying the Accounting for Income Taxes (Topic 740)”. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. Adoption of the new standard did not materially impact the Company’s consolidated financial statements.

Recent Accounting Guidance Not Yet Adopted

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”, which requires entities to measure all expected credit losses for financial assets held at the reporting data based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company is currently assessing the impact that adopting this new accounting standard will have on our consolidated financial statements.

2. DEBT

On May 1, 2019, Ultralife, Southwest Electronic Energy Corporation, a Texas corporation (“SWE”), and CLB, INC., a Texas corporation and wholly owned subsidiary of SWE (“CLB”), as borrowers, entered into the First Amendment Agreement (the “First Amendment Agreement”) with KeyBank National Association (“KeyBank” or the “Bank”), as lender and administrative agent, to amend the Credit and Security Agreement by and among Ultralife and KeyBank dated May 31, 2017 (the “Credit Agreement”, and together with the First Amendment Agreement, the “Amended Credit Agreement”).

The Amended Credit Agreement, among other things, provides for a five-year, $8,000 senior secured term loan (the “Term Loan Facility”) and extends the term of the $30,000 senior secured revolving credit facility (the “Revolving Credit Facility”, and together with the Term Loan Facility, the “Credit Facilities”) through May 31, 2022. Up to six months prior to May 31, 2022, the Revolving Credit Facility may be increased to $50,000 with the Bank’s concurrence.

As of March 31, 2021, the Company had $1,081 outstanding principal on the Term Loan Facility, all of which is included in current portion of long-term debt on the consolidated balance sheet, and no amounts outstanding on the Revolving Credit Facility. As of March 31, 2021, total unamortized debt issuance costs of $88 associated with the Amended Credit Agreement, including placement, renewal and legal fees, are classified as a reduction of the current portion of long-term debt on the consolidated balance sheet. Debt issuance costs are amortized to interest expense over the remaining term of the Credit Facilities.

5

 

The Company is required to repay the borrowings under the Term Loan Facility in sixty (60) equal consecutive monthly payments which commenced on May 31, 2019, in arrears, together with applicable interest.  All unpaid principal and accrued and unpaid interest with respect to the Term Loan Facility is due and payable in full on April 30, 2024.  All unpaid principal and accrued and unpaid interest with respect to the Revolving Credit Facility is due and payable in full on May 31, 2022.  The Company may voluntarily prepay principal amounts outstanding at any time subject to certain restrictions.  The Company made voluntary prepayments of $4,200 during the year ended December 31, 2020. No other voluntary prepayments have been made as of March 31, 2021.

In addition to the customary affirmative and negative covenants, the Company must maintain a consolidated fixed charge coverage ratio equal to or greater than 1.15 to 1.0, and a consolidated senior leverage ratio equal to or less than 2.5 to 1.0, each as defined in the Amended Credit Agreement.  The Company was in full compliance with its covenants under the Amended Credit Agreement as of March 31, 2021.

Borrowings under the Credit Facilities are secured by substantially all the assets of the Company.  Availability under the Revolving Credit Facility is subject to certain borrowing base limits based on receivables and inventories.

Interest will accrue on outstanding indebtedness under the Credit Facilities at the Base Rate or the Overnight LIBOR Rate, as selected by the Company, plus the applicable margin.  The Base Rate is the higher of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 50 basis points, and (c) the Overnight LIBOR Rate plus 100 basis points.  The applicable margin ranges from zero (0) to negative 50 basis points for the Base Rate and from 185 to 215 basis points for the Overnight LIBOR Rate and are determined based on the Company’s senior leverage ratio.

The Company must pay a fee of 0.1% to 0.2% based on the average daily unused availability under the Revolving Credit Facility.

Payments must be made by the Company to the extent borrowings exceed the maximum amount then permitted to be drawn on the Credit Facilities and from the proceeds of certain transactions. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and the Bank will have other customary remedies including resort to the security interest the Company provided to the Bank.

3. EARNINGS PER SHARE

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Ultralife by the weighted average shares outstanding during the period.  Diluted EPS includes the dilutive effect of securities, if any, and is calculated using the treasury stock method.  For the three-month period ended March 31, 2021, 459,650 stock options and 20,832 restricted stock awards were included in the calculation of diluted EPS as such securities are dilutive.  Inclusion of these securities resulted in 178,781 additional shares in the calculation of fully diluted earnings per share.  For the comparable three-month period ended March 31, 2020, 878,408 stock options and 25,833 restricted stock awards were included in the calculation of diluted EPS resulting in 211,286 additional shares in the calculation of fully diluted earnings per share. There were 668,917 and 653,500 outstanding stock options for the three-month periods ended March 31, 2021 and March 31, 2020, respectively, which were not included in diluted EPS as the effect would be anti-dilutive.

4. SUPPLEMENTAL BALANCE SHEET INFORMATION

Fair Value Measurements and Disclosures

The fair value of financial instruments approximated their carrying values at March 31, 2021 and December 31, 2020. The fair value of cash, accounts receivable, accounts payable, accrued liabilities, and the current portion of long-term debt approximates carrying value due to the short-term nature of these instruments.

Restricted cash is included as a component of the cash balance for purposes of the consolidated statements of cash flows.

Inventories

Inventories are stated at the lower of cost or net realizable value, net of obsolescence reserves, with cost determined under the first-in, first-out (FIFO) method. The composition of inventories, net was:

Amortization included in research and development expenses was $33 and $31 for the three-month periods ended March 31, 2021 and March 31, 2020, respectively.

5. STOCK-BASED COMPENSATION

We recorded non-cash stock compensation expense in each period as follows:

	Three-month period ended
	March 31,		March 31,
	2021		2020
Stock options	$	163	$	192
Restricted stock grants		21		38
Total	$	184	$	230

We have stock options outstanding from various stock-based employee compensation plans for which we record compensation cost relating to share-based payment transactions in our financial statements. As of March 31, 2021, there was $407 of total unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted average period of 0.9 years.

The following table summarizes stock option activity for the three-month period ended March 31, 2021:

	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value
Outstanding at January 1, 2021		1,217,163		$	6.50
Granted		-			-
Exercised		(76,599	)		4.00
Forfeited or expired		(11,997	)		7.00
Outstanding at March 31, 2021		1,128,567		$	6.66	3.98	$	2,101
Vested and expected to vest at March 31, 2021		1,029,341		$	6.56	3.83	$	2,019
Exercisable at March 31, 2021		658,855		$	6.04	2.85	$	1,659

Cash received from stock option exercises under our stock-based compensation plans for the three-month periods ended March 31, 2021 and March 31, 2020 was $31 and $29, respectively.

In October 2020, 5,000 shares of restricted stock were awarded to an employee at a weighted-average grant date fair value of $6.08 per share. In April 2019, 20,000 shares of restricted stock were awarded to certain of our employees at a weighted-average grant date fair value of $11.12 per share. In January 2018, 17,500 shares of restricted stock were awarded to certain of our employees at a weighted-average grant date fair value of $7.16 per share. All outstanding restricted shares vest in equal annual installments over three (3) years. Unrecognized compensation cost related to these restricted shares was $50 at March 31, 2021, which is expected to be recognized over a weighted average period of 1.8 years.

6. INCOME TAXES

Our effective tax rate for the three-month periods ended March 31, 2021 and March 31, 2020 was 24.2% and 22.9%, respectively. The period-over-period change was primarily attributable to the geographic mix of earnings.

As of December 31, 2020, we have domestic net operating loss (“NOL”) carryforwards of $47,755, which expire 2021 thru 2035, and domestic tax credits of $2,070, which expire 2028 thru 2039, available to reduce future taxable income.  As of March 31, 2021, management has concluded it is more likely than not that these domestic NOL and credit carryforwards will be fully utilized. 

As of March 31, 2021, for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately $11,000, nearly all of which can be carried forward indefinitely. Utilization of the net operating losses may be limited due to the change in the past U.K. operation and cannot currently be used to reduce taxable income at our other U.K. subsidiary, Accutronics Ltd.  There are no other deferred tax assets related to the past U.K. operations.

As of March 31, 2021, we have not recognized a valuation allowance against our other foreign deferred tax assets, as realization is considered to be more likely than not.

As of March 31, 2021, the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations, other than earnings generated in the U.K.

There were no unrecognized tax benefits related to uncertain tax positions at March 31, 2021 and December 31, 2020.

As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions.  We are routinely subject to examination by taxing authorities in these various jurisdictions.  In August 2020, the Internal Revenue Service (“IRS”) completed its examination of the Company’s federal tax returns for 2016-2018 with no material adjustments identified.  Our U.S. tax matters for 2019 and 2020 remain subject to IRS examination.  Our U.S. tax matters for 2001, 2002, 2005-2007 and 2011-2015 also remain subject to IRS examination due to the remaining availability of NOL carryforwards generated in those years. Our U.S. tax matters for 2001, 2002, 2005-2007 and 2011-2020 remain subject to examination by various state and local tax jurisdictions. Our tax matters for the years 2010 through 2020 remain subject to examination by the respective foreign tax jurisdiction authorities.

7. OPERATING LEASES

The Company has operating leases predominantly for operating facilities. As of March 31, 2021, the remaining lease terms on our operating leases range from less than one year to less than four years. Renewal options not yet exercised and termination options are not reasonably certain of exercise by the Company. There is no transfer of title or option to purchase the leased assets upon expiration.

8. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

As of March 31, 2021, we have made commitments to purchase approximately $919 of production machinery and equipment.

Product Warranties

We estimate future warranty costs to be incurred for product failure rates, material usage and service costs in the development of our warranty obligations. Estimated future costs are based on actual past experience and are generally estimated as a percentage of sales over the warranty period. Changes in our product warranty liability during the first three months of 2021 and 2020 were as follows:

	Three-month period ended March 31,
	2021			2020
Accrued warranty obligations – beginning	$	149		$	195
Accruals for warranties issued		45			27
Settlements made		(23	)		(12	)
Accrued warranty obligations – ending	$	171		$	210

Contingencies and Legal Matters

We are subject to legal proceedings and claims that arise from time to time in the normal course of business. We believe that the final disposition of any such matters will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. However, recognizing that legal matters are subject to inherent uncertainties, there exists the possibility that ultimate resolution of these matters could have a material adverse impact on the Company’s financial position, results of operations or cash flows. We are not aware of any such situations at this time.

9. REVENUE RECOGNITION

Revenues are generated from the sale of products. Performance obligations are met and revenue is recognized upon transfer of control to the customer, which is generally upon shipment. When contract terms require transfer of control upon delivery at a customer’s location, revenue is recognized on the date of delivery. For products shipped under vendor managed inventory arrangements, revenue is recognized and billed when the product is consumed by the customer, at which point control has transferred and there are no further obligations by the Company. Revenue is measured as the amount of consideration we expect to receive in exchange for shipped product. Sales, value-added and other taxes billed and collected from customers are excluded from revenue. Customers, including distributors, do not have a general right of return.

Revenues recognized from prior period performance obligations for the three-month periods ended March 31, 2021 and 2020 were not material.

Deferred revenue, unbilled revenue and deferred contract costs recorded on our consolidated balance sheets as of March 31, 2021 and December 31, 2020 were not material. As of March 31, 2021 and December 31, 2020, the Company had no unsatisfied performance obligations for contracts with an original expected duration of greater than one year. Pursuant to Topic 606, we have applied the practical expedient with respect to disclosure of the deferral and future expected timing of revenue recognition for transaction price allocated to remaining performance obligations.

COVID-19

The COVID-19 pandemic has created significant economic disruption and uncertainty around the world.  The Company continues to closely monitor the developments surrounding COVID-19 and take actions to mitigate the business risks involved.  During this challenging time, we remain focused on ensuring the health and safety of our employees by implementing the protocols established by public health officials and meeting the demand of our customers.  As an essential supplier currently exempt from government-mandated shutdown directives, we are striving to ensure an uninterrupted flow of our mission critical products serving medical device, first responder, public safety, energy, and national security customers. We have maintained normal operations at all our facilities with the exception of an approximately one-month closure of our China facility as was mandated by the Chinese government through early March 2020. 

For the quarter ended March 31, 2021, we estimate that the net impact of COVID-19 was a reduction to sales of approximately $2,000, a reduction to operating income of approximately $900, a reduction of net income of approximately $700 and a reduction of diluted earnings per share of approximately $0.04. Demand for medical batteries, especially those used in ventilators, respirators, and infusion pumps, continued to be high; however, this increase was more than offset by the revenue declines in oil & gas and international industrial markets, some delays in medical battery orders for devices used for elective surgeries and the overall disruptions in supply chains and operations impacting both commercial and government/defense markets.

Overview

Consolidated revenues of $25,973 for the three-month period ended March 31, 2021, increased by $159 or 0.6%, over $25,814 during the three-month period ended March 31, 2020, reflecting a 19.4% increase in core battery sales across diversified end markets partially offset by continued softness in the oil & gas market and lower Communications Systems sales primarily due to the high shipments of vehicle amplifier-adaptor systems to support the U.S. Army’s Network Modernization initiatives in the 2020 first quarter. We have estimated that COVID-19 adversely impacted our first quarter 2021 sales by approximately $2,000.

Gross profit was $6,978, or 26.9% of revenue, compared to $7,334, or 28.4% of revenue, for the same quarter a year ago.  The 150-basis point decline primarily reflects incremental costs in 2021 associated with the transition of a multitude of new products to higher volume production as well as higher freight costs on incoming materials.  

Operating expenses increased to $6,026 during the three-month period ended March 31, 2021, compared to $5,849 during the three-month period ended March 31, 2020.  The increase of $177 or 3.0% was attributable to our continued investment in engineering and sales personnel for new product development and market launches.  Operating expenses as a percentage of sales increased 50 basis points from 22.7% for the first quarter of 2020 to 23.2% for the current quarter. 

Operating income for the three-month period ended March 31, 2021 was $952 or 3.7% of revenues compared to $1,485 or 5.7% of revenues for the year-earlier period. The 35.9% decline in operating income primarily resulted from revenue declines in oil & gas and international industrial markets, the overall disruptions in customer/third party logistics impacting both commercial and government/defense markets resulting from COVID-19 and the impact of a higher mix of new products in our Battery & Energy Products business segment.

Net income attributable to Ultralife was $671, or $0.04 per share – basic and diluted, for the three-month period ended March 31, 2021, compared to $1,059, or $0.07 per share – basic and diluted, for the three-month period ended March 31, 2020.  Adjusted EPS was $0.05 on a diluted basis for the first quarter of 2021, compared to $0.08 for the year-earlier period.  Adjusted EPS excludes the provision for deferred taxes which primarily represents non-cash charges of $168 and $242 for the 2021 and 2020 periods, respectively, for U.S. taxes which will be fully offset by net operating loss carryforwards and other tax credits for the foreseeable future.  See the section “Adjusted EPS” on Page 21 for a reconciliation of EPS to Adjusted EPS.  For the 2021 first quarter, the estimated net adverse impact of COVID-19 was approximately $0.04 on diluted EPS, and approximately $0.06 on Adjusted EPS.

Adjusted EBITDA, defined as net income attributable to Ultralife before net interest expense, provision for income taxes, depreciation and amortization, and stock-based compensation expense, plus/minus expenses/income that we do not consider reflective of our ongoing operations, amounted to $2,012 or 7.8% of revenues in the first quarter of 2021 compared to $2,522 or 9.8% of revenues for the first quarter of 2020. See the section “Adjusted EBITDA” beginning on Page 20 for a reconciliation of Adjusted EBITDA to net income attributable to Ultralife. For the first quarter of 2021, it is estimated that COVID-19 adversely impacted Adjusted EBITDA by approximately $900, or 3.6% of revenues.

As we continue to work on completing new product development projects and identify new target markets in emerging markets, we are steadily expanding our long-term opportunities to scale the business and realize the operating leverage inherent in our profitable business model.

Results of Operations

Three-Month Periods Ended March 31, 2021 and March 31, 2020

Revenues. Consolidated revenues for the three-month period ended March 31, 2021 amounted to $25,973 an increase of $159 or 0.6%, over $25,814 for the three-month period ended March 31, 2020. Overall, commercial sales decreased 3.1% while government/defense sales increased 5.6% from the 2020 period. For the quarter ended March 31, 2021, we estimate that the net adverse impact of COVID-19 on revenues was approximately $2,000. Demand for medical batteries, especially those used in ventilators, respirators and infusion pumps, continued to be high; however, this increase was more than offset by the revenue declines in oil & gas and the overall disruptions in customer and third-party logistics which delayed certain shipments.

17

Battery & Energy Products revenues increased $1,350, or 6.5%, from $20,761 for the three-month period ended March 31, 2020 to $22,111 for the three-month period ended March 31, 2021. Excluding oil & gas sales, revenues increased 19.4% over the prior year reflecting a 32.2% increase in medical sales resulting from an increase in demand for our batteries used in ventilators, respirators, infusion pumps and other medical devices associated with COVID-19, and a 30.3% increase in government/defense sales due primarily to higher demand from a large global defense contractor. This increase was more than offset by a 30.0% decrease in oil & gas market battery sales representative of current market conditions for that sector.

Communications Systems revenues decreased $1,191, or 23.6%, from $5,053 during the three-month period ended March 31, 2020 to $3,862 for the three-month period ended March 31, 2021. This decrease is primarily attributable to higher first quarter 2020 shipments of mounted power amplifiers to support the U.S. Army’s Network Modernization and other initiatives under the delivery orders announced in October 2018.  The October 2018 delivery orders to the U.S. Army were completed in the second quarter of 2020. 

Cost of Products Sold / Gross Profit.  Cost of products sold totaled $18,995 for the quarter ended March 31, 2021, an increase of $515, or 2.8%, from the $18,480 reported for the same three-month period a year ago. Consolidated cost of products sold as a percentage of total revenue increased from 71.6% for the three-month period ended March 31, 2020 to 73.1% for the three-month period ended March 31, 2021. Correspondingly, consolidated gross margin decreased from 28.4% for the three-month period ended March 31, 2020, to 26.9% for the three-month period ended March 31, 2021, primarily reflecting sales mix and costs associated with the transition of new products to higher volume production.          

For our Battery & Energy Products segment, gross profit for the first quarter of 2021 was $5,436, an increase of $120 or 2.3% over gross profit of $5,316 for the first quarter of 2020. Battery & Energy Products’ gross margin of 24.6% decreased by 100 basis points from the 25.6% gross margin for the year-earlier period, reflecting sales mix, incremental costs associated with the transition of new products to higher volume production and higher freight costs on incoming materials.

For our Communications Systems segment, gross profit for the first quarter of 2021 was $1,542 or 39.9% of revenues, compared to gross profit of $2,018 or 39.9% of revenues, for the first quarter of 2020.

Operating Expenses. Operating expenses for the three-month period ended March 31, 2021 were $6,026, an increase of $177 or 3.0% from the $5,849 for the three-month period ended March 31, 2020. The increase in operating expenses is attributable to a 6.4% increase in core engineering and technology expenses and a 9.6% increase in sales and marketing expenses reflecting our investment in engineering and sales resources for new product development and market launches.

Overall, operating expenses as a percentage of revenues were 23.2% for the quarter ended March 31, 2021 compared to 22.7% for the quarter ended March 31, 2020. Amortization expense associated with intangible assets related to our acquisitions was $154 for the first quarter of 2021 ($121 in selling, general and administrative expenses and $33 in research and development costs), compared with $149 for the first quarter of 2020 ($118 in selling, general, and administrative expenses and $31 in research and development costs). Research and development costs were $1,647 for the three-month period ended March 31, 2021, an increase of $99 or 6.4%, from $1,548 for the three-months ended March 31, 2020. The increase is largely attributable to the hiring of engineering resources to support new product development in our Battery & Energy Products business. Selling, general, and administrative expenses increased $78 or 1.8%, to $4,379 for the first quarter of 2021 from $4,301 for the first quarter of 2020. The increase is primarily attributable to increasing sales resources to support our new product market launches, while closely monitoring all discretionary spending.

Other Expense. Other expense totaled $56 for the three-month period ended March 31, 2021 compared to $92 for the three-month period ended March 31, 2020. Interest and financing expense decreased $118, or 67.8%, from $174 for the first quarter of 2020 to $56 for the comparable period in 2021. The decrease is primarily due to the continued reduction of debt incurred in connection with the financing of the SWE acquisition. Miscellaneous income, which primarily represents gains and losses on foreign currency transactions, amounted to $0 for the first quarter of 2021 compared with miscellaneous income of $82 for the first quarter of 2020, which primarily reflects the translation of U.S.-denominated transactions and balances of Accutronics (U.K.) for the respective periods. The U.S. dollar weakened against the Pound Sterling by 0.9% during the 2021 first quarter, whereas the U.S. dollar strengthened against the Pound Sterling by 6.2% during the 2020 first quarter.

18

Income Taxes. The tax provision for the 2021 first quarter was $217 compared to $319 for the first quarter of 2020. Our effective tax rate increased to 24.2% for the first quarter of 2021 as compared to 22.9% for the first quarter of 2020, primarily attributable to the geographic mix of earnings.  The income tax provision for the first quarter of 2021 is comprised of a $49 current provision for taxes expected to be paid on income from our foreign operations, representing a cash-based effective tax rate of 5.5%, and a $168 deferred tax provision which primarily represents non-cash charges for U.S. taxes which will be fully offset by NOL carryforwards and other tax credits for the foreseeable future.  For the 2020 period, the income tax provision was comprised of a $77 current tax provision, representing a cash-based effective tax rate of 5.5%, and a $242 deferred tax provision.  See Note 6 in the Notes to Consolidated Financial Statements in Item 1 of Part I of this Form 10-Q for additional information regarding our income taxes.

Adjusted EPS excludes the provision for deferred taxes of $168 and $242 for the 2021 and 2020 periods, respectively, which primarily represents non-cash charges for U.S. taxes which will be fully offset by NOL carryforwards and other tax credits for the foreseeable future.  See the section “Adjusted EPS” on Page 21 for a reconciliation of EPS to Adjusted EPS.

Net Income Attributable to Ultralife. Net income attributable to Ultralife was $671, or $0.04 per share – basic and diluted, for the three-month period ended March 31, 2021, compared to $1,059, or $0.07 per share – basic and diluted, for the three-month period ended March 31, 2020. Adjusted EPS was $0.05 on a diluted basis for the first quarter of 2021, representing a 35.8% decrease from Adjusted EPS on a diluted basis of $0.08 for the 2020 period. For the 2021 first quarter, the estimated net adverse impact of COVID-19 was approximately $0.04 on diluted EPS, and approximately $0.06 on Adjusted EPS. Weighted average shares outstanding used to compute diluted earnings per share increased from 16,086,744 in the first quarter of 2020 to 16,152,260 in the first quarter of 2021. The increase is attributable to stock option exercises since the first quarter of 2020 and an increase in the weighted average stock price used to compute weighted average shares outstanding from $6.71 for the first quarter of 2020 to $7.32 for the first quarter of 2021.

Adjusted EBITDA

In evaluating our business, we consider and use Adjusted EBITDA, a non-GAAP financial measure, as a supplemental measure of our operating performance. We define Adjusted EBITDA as net income attributable to Ultralife before interest expense, provision for income taxes, depreciation and amortization, and stock-based compensation expense. We also use Adjusted EBITDA as a supplemental measure to review and assess our operating performance and to enhance comparability between periods. We believe the use of Adjusted EBITDA facilitates investors’ understanding of operating performance from period to period by backing out potential differences caused by variations in such items as capital structures (affecting relative interest expense and stock-based compensation expense), the amortization of intangible assets acquired through our business acquisitions (affecting relative amortization expense and provision (benefit) for income taxes), the age and book value of facilities and equipment (affecting relative depreciation expense) and one-time charges/benefits relating to income taxes. We also present Adjusted EBITDA from operations because we believe it is frequently used by securities analysts, investors and other interested parties as a measure of financial performance. We reconcile Adjusted EBITDA to net income attributable to Ultralife, the most comparable financial measure under GAAP.

We use Adjusted EBITDA in our decision-making processes relating to the operation of our business together with GAAP financial measures such as operating income. We believe that Adjusted EBITDA permits a comparative assessment of our operating performance, relative to our performance based on our GAAP results, while isolating the effects of depreciation and amortization, which may vary from period to period without any correlation to underlying operating performance, and of stock-based compensation, which is a non-cash expense that varies widely among companies. We believe that by presenting Adjusted EBITDA, we assist investors in gaining a better understanding of our business on a going forward basis. We provide information relating to our Adjusted EBITDA so that securities analysts, investors and other interested parties have the same data that we employ in assessing our overall operations. We believe that trends in our Adjusted EBITDA are a valuable indicator of our operating performance on a consolidated basis and of our ability to produce operating cash flows to fund working capital needs, to service debt obligations and to fund capital expenditures.

The term Adjusted EBITDA is not defined under GAAP, and is not a measure of operating income, operating performance or liquidity presented in accordance with GAAP. Our Adjusted EBITDA has limitations as an analytical tool, and when assessing our operating performance, Adjusted EBITDA should not be considered in isolation or as a substitute for net income attributable to Ultralife or other consolidated statement of operations data prepared in accordance with GAAP. Some of these limitations include, but are not limited to, the following:

● Adjusted EBITDA does not reflect (1) our cash expenditures or future requirements for capital expenditures or contractual commitments; (2) changes in, or cash requirements for, our working capital needs; (3) the interest expense, or the cash requirements necessary to service interest or principal payments, on our debt; (4) income taxes or the cash requirements for any tax payments; and (5) all of the costs associated with operating our business;

● Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized often will have to be replaced in the future, and Adjusted EBITDA from continuing operations does not reflect any cash requirements for such replacements;

● While stock-based compensation is a component of cost of products sold and operating expenses, the impact on our consolidated financial statements compared to other companies can vary significantly due to such factors as assumed life of the stock-based awards and assumed volatility of our common stock; and

● Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

We compensate for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only on a supplemental basis. Neither current nor potential investors in our securities should rely on Adjusted EBITDA as a substitute for any GAAP measures and we encourage investors to review the following reconciliation of Adjusted EBITDA to net income attributable to Ultralife.

Adjusted EPS

In evaluating our business, we consider and use Adjusted EPS, a non-GAAP financial measure, as a supplemental measure of our business performance in addition to GAAP financial measures.  We define Adjusted EPS as net income attributable to Ultralife Corporation, excluding the provision for deferred taxes, divided by our weighted average shares outstanding on both a basic and diluted basis.  We believe that this information is useful in providing period-to-period comparisons of our results by reflecting the portion of our tax provision that will be offset by our U.S. NOL carryforwards and other tax credits for the foreseeable future.  We reconcile Adjusted EPS to EPS, the most comparable financial measure under GAAP.  Neither current nor potential investors in our securities should rely on Adjusted EPS as a substitute for any GAAP measures and we encourage investors to review the following reconciliation of Adjusted EPS to EPS and net income attributable to Ultralife.

Adjusted EPS is calculated as follows for the periods presented:

	Three-month period ended
	March 31, 2021						March 31, 2020

Liquidity and Capital Resources

As of March 31, 2021, cash totaled $13,662 (including restricted cash of $88), an increase of $3,009 as compared to $10,653 of cash held at December 31, 2020, primarily attributable to cash generated from operations, including the receipt of net proceeds of $1,593 awarded in a class action lawsuit.

During the three-month period ended March 31, 2021, we generated $3,903 from our operations, as compared to a net use of $365 in operations for the three-month period ended March 31, 2020. In 2021, the cash generated from operating activities reflects the Company’s receipt during the quarter of $1,593 awarded in a class action lawsuit, net income of $679, a deferred tax provision of $168, non-cash expenses of depreciation, amortization, and stock-based compensation totaling $1,094, and a $369 reduction in net working capital primarily due to the timing of collections and disbursements.

Cash used in investing activities for the three months ended March 31, 2021 was $489 for capital expenditures, primarily for investment in automation equipment for our Battery & Energy Products business, including 3-Volt cell and thionyl chloride cell production.

Net cash used by financing activities for the three-months ended March 31, 2021 was $420, consisting of $393 of principle payments against our remaining term loan balance and $58 of tax withholdings for stock awards, partially offset by net proceeds of $31 from stock options exercises.

We continue to have significant U.S. net operating loss carryforwards available to utilize as an offset to future taxable income.  See Note 6 to the Consolidated Financial Statements of this Form 10-Q for additional information.

Going forward, we expect positive operating cash flow and the availability under our Revolving Credit Facility will be sufficient to meet our general funding requirements for the foreseeable future. 

To provide flexibility in accessing the capital market, the Company filed a shelf registration statement on Form S-3 on March 30, 2021, which was declared effective by the SEC on April 2, 2021.  Under this registration statement, upon the filing of an appropriate supplemental prospectus, we may offer and sell certain of our securities from time to time in one or more offerings, at our discretion, of up to an aggregate offering price of $100 million. We intend to use the net proceeds resulting from any sales of our securities for general corporate purposes which may include, but are not limited to, potential acquisitions of complementary businesses or technologies, strategic capital expenditures to expand and protect our competitive position, and investments in the development of transformational, competitively-differentiated products for attractive growth markets.

Commitments

As of March 31, 2021, the Company had $1,081 outstanding principal on the Term Loan Facility, all of which is included in current portion of long-term debt on the consolidated balance sheet, and no amounts outstanding on the Revolving Credit Facility. The Company was in full compliance with all covenants under the Credit Facilities as of March 31, 2021.

As of March 31, 2021, we had made commitments to purchase approximately $919 of production machinery and equipment.

Critical Accounting Policies

Management exercises judgment in making important decisions pertaining to choosing and applying accounting policies and methodologies in many areas. Not only are these decisions necessary to comply with GAAP, but they also reflect management’s view of the most appropriate manner in which to record and report our overall financial performance. All accounting policies are important, and all policies described in Note 1 (“Summary of Operations and Significant Accounting Policies”) to our Consolidated Financial Statements in our 2020 Annual Report on Form 10-K should be reviewed for a greater understanding of how our financial performance is recorded and reported.

During the first quarter of 2021, there were no significant changes in the manner in which our significant accounting policies were applied or in which related assumptions and estimates were developed.

Notes to Financial Statements

Business Description and Accounting Policies [Text Block]

1. BASIS OF PRESENTATION

The accompanying unaudited Consolidated Financial Statements of Ultralife Corporation and its subsidiaries (the “Company” or “Ultralife”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions to Rule 8-03 of Regulation S-X. Accordingly, they do not include all the information and footnotes for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair presentation of the Consolidated Financial Statements have been included. Results for interim periods should not be considered indicative of results to be expected for a full year. Reference should be made to the Consolidated Financial Statements and related notes thereto contained in our Form 10-K for the year ended December 31, 2020.

The December 31, 2020 consolidated balance sheet information referenced herein was derived from audited financial statements but does not include all disclosures required by GAAP.

Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation.

Recently Adopted Accounting Guidance

Effective January 1, 2021, the Company adopted Accounting Standards Update (“ASU”) 2019-12, “Simplifying the Accounting for Income Taxes (Topic 740)”. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. Adoption of the new standard did not materially impact the Company’s consolidated financial statements.

Recent Accounting Guidance Not Yet Adopted

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”, which requires entities to measure all expected credit losses for financial assets held at the reporting data based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company is currently assessing the impact that adopting this new accounting standard will have on our consolidated financial statements.

Debt Disclosure [Text Block]

2. DEBT

On May 1, 2019, Ultralife, Southwest Electronic Energy Corporation, a Texas corporation (“SWE”), and CLB, INC., a Texas corporation and wholly owned subsidiary of SWE (“CLB”), as borrowers, entered into the First Amendment Agreement (the “First Amendment Agreement”) with KeyBank National Association (“KeyBank” or the “Bank”), as lender and administrative agent, to amend the Credit and Security Agreement by and among Ultralife and KeyBank dated May 31, 2017 (the “Credit Agreement”, and together with the First Amendment Agreement, the “Amended Credit Agreement”).

The Amended Credit Agreement, among other things, provides for a five-year, $8,000 senior secured term loan (the “Term Loan Facility”) and extends the term of the $30,000 senior secured revolving credit facility (the “Revolving Credit Facility”, and together with the Term Loan Facility, the “Credit Facilities”) through May 31, 2022. Up to six months prior to May 31, 2022, the Revolving Credit Facility may be increased to $50,000 with the Bank’s concurrence.

As of March 31, 2021, the Company had $1,081 outstanding principal on the Term Loan Facility, all of which is included in current portion of long-term debt on the consolidated balance sheet, and no amounts outstanding on the Revolving Credit Facility. As of March 31, 2021, total unamortized debt issuance costs of $88 associated with the Amended Credit Agreement, including placement, renewal and legal fees, are classified as a reduction of the current portion of long-term debt on the consolidated balance sheet. Debt issuance costs are amortized to interest expense over the remaining term of the Credit Facilities.

The Company is required to repay the borrowings under the Term Loan Facility in sixty (60) equal consecutive monthly payments which commenced on May 31, 2019, in arrears, together with applicable interest.  All unpaid principal and accrued and unpaid interest with respect to the Term Loan Facility is due and payable in full on April 30, 2024.  All unpaid principal and accrued and unpaid interest with respect to the Revolving Credit Facility is due and payable in full on May 31, 2022.  The Company may voluntarily prepay principal amounts outstanding at any time subject to certain restrictions.  The Company made voluntary prepayments of $4,200 during the year ended December 31, 2020. No other voluntary prepayments have been made as of March 31, 2021.

In addition to the customary affirmative and negative covenants, the Company must maintain a consolidated fixed charge coverage ratio equal to or greater than 1.15 to 1.0, and a consolidated senior leverage ratio equal to or less than 2.5 to 1.0, each as defined in the Amended Credit Agreement.  The Company was in full compliance with its covenants under the Amended Credit Agreement as of March 31, 2021.

Borrowings under the Credit Facilities are secured by substantially all the assets of the Company.  Availability under the Revolving Credit Facility is subject to certain borrowing base limits based on receivables and inventories.

Interest will accrue on outstanding indebtedness under the Credit Facilities at the Base Rate or the Overnight LIBOR Rate, as selected by the Company, plus the applicable margin.  The Base Rate is the higher of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 50 basis points, and (c) the Overnight LIBOR Rate plus 100 basis points.  The applicable margin ranges from zero (0) to negative 50 basis points for the Base Rate and from 185 to 215 basis points for the Overnight LIBOR Rate and are determined based on the Company’s senior leverage ratio.

The Company must pay a fee of 0.1% to 0.2% based on the average daily unused availability under the Revolving Credit Facility.

Payments must be made by the Company to the extent borrowings exceed the maximum amount then permitted to be drawn on the Credit Facilities and from the proceeds of certain transactions. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and the Bank will have other customary remedies including resort to the security interest the Company provided to the Bank.

Notes to Financial Statements

Earnings Per Share [Text Block]

3. EARNINGS PER SHARE

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Ultralife by the weighted average shares outstanding during the period.  Diluted EPS includes the dilutive effect of securities, if any, and is calculated using the treasury stock method.  For the three-month period ended March 31, 2021, 459,650 stock options and 20,832 restricted stock awards were included in the calculation of diluted EPS as such securities are dilutive.  Inclusion of these securities resulted in 178,781 additional shares in the calculation of fully diluted earnings per share.  For the comparable three-month period ended March 31, 2020, 878,408 stock options and 25,833 restricted stock awards were included in the calculation of diluted EPS resulting in 211,286 additional shares in the calculation of fully diluted earnings per share. There were 668,917 and 653,500 outstanding stock options for the three-month periods ended March 31, 2021 and March 31, 2020, respectively, which were not included in diluted EPS as the effect would be anti-dilutive.

The fair value of financial instruments approximated their carrying values at March 31, 2021 and December 31, 2020. The fair value of cash, accounts receivable, accounts payable, accrued liabilities, and the current portion of long-term debt approximates carrying value due to the short-term nature of these instruments.

Restricted cash is included as a component of the cash balance for purposes of the consolidated statements of cash flows.

Inventories

Inventories are stated at the lower of cost or net realizable value, net of obsolescence reserves, with cost determined under the first-in, first-out (FIFO) method. The composition of inventories, net was:

	March 31,		December 31,

6. INCOME TAXES

Our effective tax rate for the three-month periods ended March 31, 2021 and March 31, 2020 was 24.2% and 22.9%, respectively. The period-over-period change was primarily attributable to the geographic mix of earnings.

As of December 31, 2020, we have domestic net operating loss (“NOL”) carryforwards of $47,755, which expire 2021 thru 2035, and domestic tax credits of $2,070, which expire 2028 thru 2039, available to reduce future taxable income.  As of March 31, 2021, management has concluded it is more likely than not that these domestic NOL and credit carryforwards will be fully utilized. 

As of March 31, 2021, for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately $11,000, nearly all of which can be carried forward indefinitely. Utilization of the net operating losses may be limited due to the change in the past U.K. operation and cannot currently be used to reduce taxable income at our other U.K. subsidiary, Accutronics Ltd.  There are no other deferred tax assets related to the past U.K. operations.

As of March 31, 2021, we have not recognized a valuation allowance against our other foreign deferred tax assets, as realization is considered to be more likely than not.

As of March 31, 2021, the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations, other than earnings generated in the U.K.

There were no unrecognized tax benefits related to uncertain tax positions at March 31, 2021 and December 31, 2020.

As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions.  We are routinely subject to examination by taxing authorities in these various jurisdictions.  In August 2020, the Internal Revenue Service (“IRS”) completed its examination of the Company’s federal tax returns for 2016-2018 with no material adjustments identified.  Our U.S. tax matters for 2019 and 2020 remain subject to IRS examination.  Our U.S. tax matters for 2001, 2002, 2005-2007 and 2011-2015 also remain subject to IRS examination due to the remaining availability of NOL carryforwards generated in those years. Our U.S. tax matters for 2001, 2002, 2005-2007 and 2011-2020 remain subject to examination by various state and local tax jurisdictions. Our tax matters for the years 2010 through 2020 remain subject to examination by the respective foreign tax jurisdiction authorities.

Purchase Commitments

As of March 31, 2021, we have made commitments to purchase approximately $919 of production machinery and equipment.

Product Warranties

We estimate future warranty costs to be incurred for product failure rates, material usage and service costs in the development of our warranty obligations. Estimated future costs are based on actual past experience and are generally estimated as a percentage of sales over the warranty period. Changes in our product warranty liability during the first three months of 2021 and 2020 were as follows:

Contingencies and Legal Matters

We are subject to legal proceedings and claims that arise from time to time in the normal course of business. We believe that the final disposition of any such matters will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. However, recognizing that legal matters are subject to inherent uncertainties, there exists the possibility that ultimate resolution of these matters could have a material adverse impact on the Company’s financial position, results of operations or cash flows. We are not aware of any such situations at this time.

Notes to Financial Statements

Revenue from Contract with Customer [Text Block]

9. REVENUE RECOGNITION

Revenues are generated from the sale of products. Performance obligations are met and revenue is recognized upon transfer of control to the customer, which is generally upon shipment. When contract terms require transfer of control upon delivery at a customer’s location, revenue is recognized on the date of delivery. For products shipped under vendor managed inventory arrangements, revenue is recognized and billed when the product is consumed by the customer, at which point control has transferred and there are no further obligations by the Company. Revenue is measured as the amount of consideration we expect to receive in exchange for shipped product. Sales, value-added and other taxes billed and collected from customers are excluded from revenue. Customers, including distributors, do not have a general right of return.

Revenues recognized from prior period performance obligations for the three-month periods ended March 31, 2021 and 2020 were not material.

Deferred revenue, unbilled revenue and deferred contract costs recorded on our consolidated balance sheets as of March 31, 2021 and December 31, 2020 were not material. As of March 31, 2021 and December 31, 2020, the Company had no unsatisfied performance obligations for contracts with an original expected duration of greater than one year. Pursuant to Topic 606, we have applied the practical expedient with respect to disclosure of the deferral and future expected timing of revenue recognition for transaction price allocated to remaining performance obligations.

Effective January 1, 2021, the Company adopted Accounting Standards Update (“ASU”) 2019-12, “Simplifying the Accounting for Income Taxes (Topic 740)”. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. Adoption of the new standard did not materially impact the Company’s consolidated financial statements.

Recent Accounting Guidance Not Yet Adopted

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments”, which requires entities to measure all expected credit losses for financial assets held at the reporting data based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. This guidance is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company is currently assessing the impact that adopting this new accounting standard will have on our consolidated financial statements.
