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 notes 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, 2022.

The December 31, 2022 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.

Significant Accounting Policies

During the quarter ended June 30, 2023, in consultation with third party experts, the Company completed an analysis to determine and verify its eligibility for the Employee Retention Credit (“ERC”), which is a refundable tax credit against certain employment taxes under Section 2301 of the Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”) and the American Rescue Plan of 2021, and filed the necessary amended payroll tax forms with the Internal Revenue Service to claim a refund for the credit. The ERC refund receivable of $1,544 is included in prepaid expenses and other current assets on our consolidated balance sheet as of June 30, 2023, and the benefit is recognized as other income (expense) on our consolidated statement of income for the three and six-month periods ended June 30, 2023.

Recently Adopted Accounting Guidance

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 date 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 adoption of this new accounting standard did not have a material impact on our consolidated financial statements.

2.	*DEBT*

On December 13, 2021, Ultralife, Southwest Electronic Energy Corporation, a Texas corporation and wholly owned subsidiary of Ultralife (“SWE”), CLB, INC., a Texas corporation and wholly owned subsidiary of SWE (“CLB”), Ultralife Excell Holding Corp., a Delaware corporation and wholly owned subsidiary of Ultralife (“UEHC”), Ultralife Canada Holding Corp., a Delaware corporation and wholly owned subsidiary of UEHC (“UCHC”), and Excell Battery Corporation USA, a Texas corporation and wholly owned subsidiary of UEHC (“Excell USA”), as borrowers, entered into the Second Amendment Agreement with KeyBank National Association (“KeyBank” or the “Bank”), as lender and administrative agent, to amend the Credit and Security Agreement dated May 31, 2017 as amended by the First Amendment Agreement by and among Ultralife, SWE, CLB and KeyBank dated May 1, 2019 (the “Credit Agreement”). On November 28, 2022, Ultralife, SWE, CLB, UEHC, UCHC, Excell USA, and Excell Battery Canada ULC, a British Columbia unlimited liability corporation and wholly owned subsidiary of UCHC (“Excell Canada”), entered into that certain Third Amendment Agreement with KeyBank, to further amend the Credit Agreement to, among other things, facilitate the joinder of Excell Canada as a guarantor under the Credit Agreement and to replace the LIBOR benchmark thereunder with SOFR (the “Third Amendment Agreement”, and together with the Second Amendment Agreement and the Credit Agreement, the “Amended Credit Agreement”).

The Amended Credit Agreement, among other things, provides for a 5-year, $10,000 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 “Amended Credit Facilities”) through May 30, 2025. Up to six months prior to May 30, 2025, the Revolving Credit Facility may be increased to $50,000 with the Bank’s concurrence.

As of June 30, 2023, the Company had $7,167 outstanding principal on the Term Loan Facility, $2,000 of which is included in current portion of long-term debt on the balance sheet, and $17,630 outstanding on the Revolving Credit Facility. As of June 30, 2023, total unamortized debt issuance costs of $155, including placement, renewal and legal fees associated with the Amended Credit Agreement, are classified as a reduction of long-term debt on the balance sheet. Debt issuance costs are amortized to interest expense over the term of the Amended Credit Facilities.

The remaining availability under the Revolving Credit Facility is subject to certain borrowing base limits based on trade receivables and inventories.

The Company is required to repay the borrowings under the Term Loan Facility in equal consecutive monthly payments commencing on February 1, 2022, 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 January 1, 2027. All unpaid principal and accrued and unpaid interest with respect to the Revolving Credit Facility is due and payable in full on May 30, 2025. The Company may voluntarily prepay principal amounts outstanding at any time subject to certain restrictions.

In addition to the customary affirmative and negative covenants, the Company must maintain a Consolidated Senior Leverage Ratio, as defined in the Amended Credit Agreement, of equal to or less than 3.5 to 1.0 for the fiscal quarters ending December 31, 2022 and March 31, 2023, and equal to or less than 3.0 to 1.0 for the fiscal quarters ending June 30, 2023 and thereafter. The Company was in full compliance with its covenants under the Amended Credit Agreement as of June 30, 2023.

Borrowings under the Amended Credit Facilities are secured by substantially all the assets of the Company and its subsidiaries.

Upon the effectiveness of the Third Amendment Agreement, interest accrues on outstanding indebtedness under the Amended Credit Facilities at the Daily Simple SOFR Rate, plus an index spread adjustment of 0.10%, plus the applicable margin. The applicable margin ranges from 185 to 215 basis points and is determined based on the Company’s senior leverage ratio.

The Company must pay a fee of 0.15% to 0.25% 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 Amended 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 (loss) per share (“EPS”) is computed by dividing net income (loss) 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 June 30, 2023, there were 4,166 outstanding stock options and 2,500 unvested restricted stock awards included in the calculation of diluted weighted average shares outstanding, as such securities were dilutive, resulting in 2,334 potential common shares included in the calculation of diluted EPS. For the comparable three-month period ended June 30, 2022, 135,163 outstanding stock options and unvested 5,000 restricted stock awards were included in the calculation of diluted EPS, resulting in 20,352 potential common shares included in the calculation of diluted EPS. There were 1,289,862 and 1,073,077 outstanding stock options for the three-month periods ended June 30, 2023 and 2022, respectively, not included in EPS as the effect would be anti-dilutive.

For the six-month period ended June 30, 2023, there were no outstanding stock options and 2,500 unvested restricted stock awards included in the calculation of diluted weighted average shares outstanding, resulting in 2,157 potential common shares included in the calculation of diluted EPS. For the comparable six-month period ended June 30, 2022, 135,163 outstanding stock options and 5,000 unvested restricted stock awards were included in the calculation of diluted EPS, resulting in 24,751 potential common shares included in the calculation of diluted EPS. There were 1,294,028 and 1,073,077 outstanding stock options for the six-month periods ended June 30, 2023 and 2022, respectively, not included in EPS as the effect would be anti-dilutive.

5.	*STOCK-BASED COMPENSATION*

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

	Three-month period ended				Six-month period ended
	June 30,		June 30,		June 30,		June 30,
	2023		2022		2023		2022

Restricted stock		1		3		2		11
Total	$	154	$	184	$	293	$	373

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 June 30, 2023, there was $438 of total unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted average period of 1.1 years.

The following table summarizes stock option activity for the six-month period ended June 30, 2023:

	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding at January 1, 2023		1,425,693		$	6.72
Granted		12,500		$	4.07
Exercised		(44,390	)	$	4.29
Forfeited or expired		(99,775	)	$	4.84
Outstanding at June 30, 2023		1,294,028		$	6.93		3.66	$	15,640
Vested and expected to vest at June 30, 2023		1,188,048		$	7.01		3.52	$	13,124
Exercisable at June 30, 2023		858,695		$	7.44		2.45	$	2,304

Cash received from stock option exercises under our stock-based compensation plans for the three-month periods ended June 30, 2023 and June 30, 2022 was $62 and $0, respectively. Cash received from stock option exercises under our stock-based compensation plans for the six-month periods ended June 30, 2023 and June 30, 2022 was $62 and $113, respectively.

Outstanding restricted shares vest in equal annual installments over three (3) years. Unrecognized compensation cost related to outstanding restricted shares at June 30, 2023 was $1.

6.	*INCOME TAXES*

Our effective tax rate for the six-month periods ended June 30, 2023 and June 30, 2022 was 29.2% and (30.5%), respectively. The period-over-period change was primarily attributable to the geographic mix of our operating results and the larger impact of discrete adjustments in the prior year.

As of December 31, 2022, we have domestic net operating loss (“NOL”) carryforwards of $40,952, which expire 2025 through 2035, and domestic tax credits of $2,600, which expire 2028 through 2042, available to reduce future taxable income. As of June 30, 2023, management has concluded it is more likely than not that these domestic NOL and credit carryforwards will be fully utilized.

As of June 30, 2023, for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately $10,000, 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 June 30, 2023, 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 June 30, 2023, 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 June 30, 2023 and December 31, 2022.

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. Our U.S. tax matters for 2019-2022 remain subject to IRS examination. Our U.S. tax matters for 2005-2007 and 2011-2015 also remain subject to IRS examination due to the remaining availability of net operating loss carryforwards generated in those years. Our U.S. tax matters for 2005-2007 and 2011-2022 remain subject to examination by various state and local tax jurisdictions. Our tax matters for the years 2013 through 2022 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 June 30, 2023, the remaining lease terms on our operating leases range from approximately one (1) year to eight (8) years. Lease terms include renewal options reasonably certain of exercise. There is no transfer of title or option to purchase the leased assets upon expiration. There are no residual value guarantees or material restrictive covenants.

The components of lease expense for the current and prior-year comparative periods were as follows:

	Three months ended				Six months ended
	June 30, 2023		June 30, 2022		June 30, 2023		June 30, 2022
Operating lease cost	$	239	$	226	$	480	$	458
Variable lease cost		29		23		57		47
Total lease cost	$	268	$	249	$	537	$	505

Cash paid for amounts included in the measurement of lease liabilities:
Operating cash flows from operating leases	$	494	$	449
Right-of-use assets obtained in exchange for lease liabilities:	$	310	$	-

Supplemental consolidated balance sheet information related to leases was as follows:

	Balance sheet classification	June 30, 2023			December 31, 2022

8.	*COMMITMENTS AND CONTINGENCIES*

Purchase Commitments

As of June 30, 2023, we have made commitments to purchase approximately $1,023 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 six months of 2023 and 2022 were as follows:

	Six-month period ended June 30,
	2023			2022
Accrued warranty obligations – beginning	$	323		$	133
Accruals for warranties issued		172			25
Settlements made		(62	)		(26	)
Accrued warranty obligations – ending	$	433		$	132

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.

Separately priced extended warranty contracts are offered on certain Communications Systems products for a duration of up to eight (8) years. Extended warranties are treated as separate performance obligations and recognized to revenue evenly over the term of the respective contract. Revenue not yet recognized on extended warranty contracts is recorded as deferred revenue on the consolidated balance sheet.

As of June 30, 2023, there was deferred revenue on extended warranty contracts of $944, comprised of $164 expected to be recognized as revenue within one (1) year and classified as accrued expenses and other current liabilities on our consolidated balance sheet, and $780 expected to be recognized as revenue over the remaining duration of the respective contracts and classified as other noncurrent liabilities on our consolidated balance sheet.

As of December 31, 2022, there was deferred revenue on extended warranty contracts of $682, comprised of $119 expected to be recognized as revenue within one (1) year and classified as accrued expenses and other current liabilities on our consolidated balance sheet, and $563 expected to be recognized as revenue over the remaining duration of the respective contracts and classified as other noncurrent liabilities on our consolidated balance sheet.

As of June 30, 2023 and December 31, 2022, the Company had no other 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.

General

We offer products and services ranging from power solutions to communications and electronics systems to customers across the globe in the government, defense and commercial sectors. With an emphasis on strong engineering and a collaborative approach to problem solving, we design and manufacture power and communications systems including: rechargeable and non-rechargeable batteries, charging systems, communications and electronics systems and accessories, and custom engineered systems related to those product lines. We continually evaluate ways to grow, including the design, development and sale of new products, expansion of our sales force to penetrate new markets and territories, as well as seeking opportunities to expand through acquisitions.

We sell our products worldwide through a variety of trade channels, including original equipment manufacturers (“OEMs”), industrial and defense supply distributors, and directly to U.S. and foreign defense departments. We enjoy strong name recognition in our markets under our Ultralife® Batteries, Lithium Power®, McDowell Research®, AMTI^TM, ABLE^TM, ACCUTRONICS™, ACCUPRO™, ENTELLION™, SWE Southwest Electronic Energy Group™, SWE DRILL-DATA™, SWE SEASAFE™, Excell Battery Group™ and Criterion Gauge brands. We have sales, operations and product development facilities in North America, Europe and Asia.

We report our results in two operating segments: Battery & Energy Products and Communications Systems. The Battery & Energy Products segment includes Lithium 9-volt, cylindrical, thin cell and other non-rechargeable batteries, in addition to rechargeable batteries, uninterruptable power supplies, charging systems and accessories. The Communications Systems segment includes RF amplifiers, power supplies, cable and connector assemblies, amplified speakers, equipment mounts, case equipment, man-portable systems, integrated communication systems for fixed or vehicle applications and communications and electronics systems design. We believe that reporting performance at the gross profit level is the best indicator of segment performance. As such, we report segment performance at the gross profit level and operating expenses as Corporate charges (See Note 10 in the notes to consolidated financial statements.)

Our website address is www.ultralifecorporation.com. We make available free of charge via a hyperlink on our website (see Investor Relations link on the website) our annual reports on Form 10-K, proxy statements, quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports and statements as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission (“SEC”). We will provide copies of these reports upon written request to the attention of Philip A. Fain, CFO, Treasurer and Secretary, Ultralife Corporation, 2000 Technology Parkway, Newark, New York, 14513. Our filings with the SEC are also available through the SEC website at www.sec.gov or at the SEC Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549 or by calling 1-800-SEC-0330.

Overview

Consolidated revenues of $42,692 for the three-month period ended June 30, 2023, increased by $10,566 or 32.9%, over $32,126 for the three-month period ended June 30, 2022, reflecting increases in government/defense sales of 111.5% and commercial sales of 9.2%. Sales for our Battery & Energy Products segment increased 12.3% from $30,140 in the second quarter of 2022 to $33,861 for the second quarter of 2023, and sales for our Communications Systems segment increased 344.6% from $1,986 to $8,831.

Gross profit was $10,588, or 24.8% of revenue, for the three-month period ended June 30, 2023, compared to $7,646, or 23.8% of revenue, for the same quarter a year ago. The 100-basis point improvement primarily resulted from higher factory volume and favorable product mix for our Communications Systems business.

Operating expenses increased to $6,923 for the three-month period ended June 30, 2023, compared to $6,853 for the three-month period ended June 30, 2022. The increase of $70 or 1.0% was primarily attributable to slightly higher new product development investments in the 2023 period. Operating expenses represented 16.2% of revenues compared to 21.3% of revenues for the year-earlier period.

Operating income for the three-month period ended June 30, 2023 was $3,665, or 8.6% of revenues, compared to $793, or 2.5% of revenues, for the year-earlier period. The increase in operating income resulted from the 32.9% increase in revenues leveraged by the 100-basis point improvement in gross margin and the 510-basis point improvement in operating expenses to revenues ratio.

Other income (expense) for the second quarter of 2023 includes an Employee Retention Credit of $1,544 under Section 2301 of the Coronavirus Aid, Relief and Economic Security Act which was filed with the Internal Revenue Service during the period.

Net income was $3,340 or $0.21 per share – basic and diluted on a GAAP basis, compared to net income of $512 million or $0.03 per share – basic and diluted for the second quarter of 2022. Adjusted EPS was $0.29 - basic and diluted for the second quarter of 2023, compared to $0.03 - basic and diluted for the 2022 period. Adjusted EPS excludes the provision for deferred taxes of $1,278 which primarily represents non-cash charges 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 23 for a reconciliation of adjusted EPS to EPS.

Adjusted EBITDA, defined as net income attributable to Ultralife before net interest expense, provision (benefit) 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 $6,296, or 14.7% of revenues, for the second quarter of 2023, compared to $2,185, or 6.8% of revenues, for the second quarter of 2022. See the section “Adjusted EBITDA” beginning on Page 21 for a reconciliation of adjusted EBITDA to net income attributable to Ultralife.

With backlog increasing to $110,875 and durable demand across our diverse end markets, the near-term highest priority remains to recapture gross margin through continued execution of price realization activities, qualification of alternate component suppliers, and lean manufacturing initiatives. These actions position us to deliver high-quality, sustainable profitable growth for 2023 generating incremental cash flow to pay down our acquisition debt and further invest in our businesses.

Three-Month Periods Ended June 30, 2023 and June 30, 2022

Revenues. Consolidated revenues for the three-month period ended June 30, 2023 were $42,692, an increase of $10,566, or 32.9%, over $32,126 for the three-month period ended June 30, 2022. Overall, government/defense sales increased 111.5% and commercial sales increased 9.2%.

Battery & Energy Products revenues increased $3,721, or 12.3%, from $30,140 for the three-month period ended June 30, 2022 to $33,861 for the three-month period ended June 30, 2023, reflecting increases of $2,268 or 9.2% in commercial sales and $1,453 and 26.6% in government/defense sales. The increase in commercial sales was driven by a $1,966 or 25.2% increase in medical sales reflecting an increased demand for our batteries used in ventilators, respirators, infusion pumps and other medical devices and a $1,694 or 17.9% increase in oil & gas sales reflecting a rebound in the energy sector. These increases in commercial sales were partially offset by a $1,392 or 18.8% decrease in industrial and other commercial sales primarily attributable to 9-Volt and our new Thionyl Chloride and thin cell battery cells for which sales are expected to rebound in future periods.

Communications Systems sales increased $6,845, or 344.6%, from $1,986 for the three-month period ended June 30, 2022 to $8,831 for the three-month period ended June 30, 2023. The increase was primarily attributable to shipments of vehicle-amplifier adaptor orders to a global defense contractor for the U.S. Army and of integrated systems of amplifiers and radio vehicle mounts to a major international defense contractor for an ongoing allied country government/defense modernization program.

Our total backlog at June 30, 2023 was $110,875 representing a 40.1% increase over the comparable $79,147 for the same period last year, with $76,400 due to ship over the remaining six months of 2023. Total backlog increased $2,772 or 2.6% compared to the backlog of $108,102 at March 31, 2023.

Cost of Products Sold / Gross Profit. Cost of products sold totaled $32,104 for the quarter ended June 30, 2023, an increase of $7,624, or 31.1%, from the $24,480 reported for the same three-month period a year ago. Consolidated cost of products sold as a percentage of total revenue decreased from 76.2% for the three-month period ended June 30, 2022 to 75.2% for the three-month period ended June 30, 2023. Correspondingly, consolidated gross margin increased from 23.8% for the three-month period ended June 30, 2022, to 24.8% for the three-month period ended June 30, 2023, primarily reflecting higher factory volume and favorable product mix for our Communications Systems business.

For our Battery & Energy Products segment, gross profit for the second quarter of 2023 was $7,543, an increase of $392 or 5.5% from gross profit of $7,151 for the second quarter of 2022. Battery & Energy Products’ gross margin of 22.3% decreased by 140-basis points from the 23.7% gross margin for the year-earlier period, primarily reflecting lingering inefficiencies resulting from the January 2023 cyberattack, disposition of certain non-conforming materials and continued investments in the transition of new products to high volume production, partially offset by improved price realization.

For our Communications Systems segment, gross profit for the second quarter of 2023 was $3,045 or 34.5% of revenues, compared to gross profit of $495 or 24.9% of revenues for the second quarter of 2022. The 960-basis point increase in gross margin was primarily due to higher factory volume and favorable product mix compared to last year’s second quarter.

Operating Expense. Overall, operating expenses were 16.2% of revenue for the quarter ended June 30, 2023 compared to 21.3% of revenue for the quarter ended June 30, 2022. Amortization expense associated with intangible assets related to our acquisitions was $227 for the second quarter of 2023 ($203 in selling, general and administrative expenses and $24 in research and development costs), compared with $323 for the second quarter of 2022 ($298 in selling, general, and administrative expenses and $25 in research and development costs). Research and development costs were $1,778 for the three-month period ended June 30, 2023, an increase of $106 or 6.3%, from $1,672 for the three-months ended June 30, 2022. The increase is largely attributable to an increase in new product development in our Communications Systems business to pursue both government/defense major programs and commercial opportunities. Selling, general, and administrative expenses were essentially flat year over year, decreasing from $5,181 for the second quarter of 2022 to $5,145 for the second quarter of 2023.

Other Income (Expense). Other income (expense) totaled $1,058 for the three-month period ended June 30, 2023 compared to ($115) for the three-month period ended June 30, 2022. Other income for the 2023 period includes an Employee Retention Credit (“ERC”) of $1,544 under Section 2301 of the Coronavirus Aid, Relief and Economic Security Act which was filed with the Internal Revenue Service during the second quarter of 2023. Interest and financing expense increased $263, or 148.6%, from ($177) for the second quarter of 2022 to ($440) for the comparable period in 2023. The increase is primarily due to the financing of our acquisition of Excell in December 2021, working capital funding resulting from the January 2023 cyberattack and rising interest rates. Excluding the $1,544 gain for the ERC, miscellaneous income (expense) amounted to ($46) for the second quarter of 2023 compared to $62 for the second quarter of 2022, primarily attributable to foreign exchange gains and loss due to fluctuations in foreign currency exchange rates.

Income Taxes. The tax provision for the 2023 second quarter was $1,375 compared to $170 for the second quarter of 2022. Our effective tax rate increased to 29.1% for the second quarter of 2023 as compared to 25.1% for the second quarter of 2022, primarily attributable to the magnitude of our income reported in the 2023 quarter, including the Employee Retention Credit, and the geographic mix of our operating results. The income tax provision for the second quarter of 2023 is comprised of a $97 current provision for taxes expected to be paid on income primarily in foreign jurisdictions, representing a cash-based effective tax rate of 2.1%, and a $1,278 deferred tax provision which primarily represents non-cash charges for U.S. taxes that will be fully offset by net operating loss carryforwards and other tax credits for the foreseeable future. For the comparable 2022 period, the income tax provision was comprised of a $143 current tax provision, representing a cash-based effective tax rate of 21.1%, and a $27 deferred tax provision. The period over period change in the cash-based effective tax rate is primarily attributable to the geographic mix of our operating results. See Note 6 to the consolidated financial statements in Item 1 of Part I of this Form 10-Q for additional information regarding our income taxes.

Net Income Attributable to Ultralife. Net income attributable to Ultralife was $3,340, or $0.21 per share – basic and diluted on a GAAP basis for the three-month period ended June 30, 2023, compared to $512, or $0.03 per share – basic and diluted, for the three-month period ended June 30, 2022. Adjusted EPS was $0.29 on a diluted basis for the second quarter of 2023, compared to $0.03 for the second quarter of 2022. Adjusted EPS excludes the provision for deferred taxes of $1,278 and $27 for the 2023 and 2022 periods, respectively, which primarily represent non-cash charges for U.S. taxes that will be fully offset by net operating loss carryforwards and other tax credits for the foreseeable future. See the section “Adjusted EPS” on Page 23 for a reconciliation of adjusted EPS to EPS.

Weighted average shares outstanding used to compute diluted earnings per share decreased from 16,149,278 for the second quarter of 2022 to 16,143,686 for the second quarter of 2023. The decrease is attributable to stock option exercises since the second quarter of 2022 offset by a decrease in the average stock price used to compute diluted shares from $4.93 for the second quarter of 2022 to $4.52 for the second quarter of 2023. Accordingly, dilutive shares of 20,352 were added to basic weighted average shares for the 2022 period compared to 2,334 for the 2023 period.

Six-Month Periods Ended June 30, 2023 and June 30, 2022

Revenues. Consolidated revenues for the six-month period ended June 30, 2023 were $74,608, an increase of $12,109, or 19.4%, over $62,499 for the six-month period ended June 30, 2022. Overall, government/defense sales increased $10,216 or 67.1% and commercial sales increased $1,893 or 4.0% . On January 25, 2023, the Company experienced a ransomware cyberattack which impacted our ability to process orders, ship products, provide services to our customers and effectively manage our sales and operating planning process over a several week period for our Newark, NY location and an even longer period for our Virginia Beach, VA location. A large portion of our time during the quarter was devoted to data restoration, systems security augmentation, and regulatory reporting of the cyberattack, all of which were successfully accomplished with no ransom paid. Management continues to work on its cybersecurity insurance claim covering the cost of engaging external cybersecurity experts and the business interruption impact.

Battery & Energy Products revenues increased $3,041, or 5.1%, from $59,290 for the six-month period ended June 30, 2022 to $62,331 for the six-month period ended June 30, 2023. The increase was attributable to a $1,893 or 4.0% increase in commercial sales and a $1,148 or 9.6% increase in government/defense sales. The increase in commercial sales was driven by a $3,601 or 19.5% increase in oil & gas sales reflecting the recent rebound in the energy sector and a $597 or 3.9% increase in medical battery sales due to the high demand for our batteries used in ventilators, respirators, infusion pumps and other medical devices. These increases in commercial sales were partially offset by a $2,305 or 16.9% decrease in industrial and other commercial market sales primarily due to timing of demand for 9-Volt and our new Thionyl Chloride and thin cell battery cells which are expected to rebound in future periods.

Communications Systems revenues increased $9,068, or 282.6%, from $3,209 for the six-month period ended June 30, 2022 to $12,277 for the six-month period ended June 30, 2023. This increase was primarily attributable to shipments of vehicle-amplifier adaptor orders to a global defense contractor for the U.S. Army and of integrated systems of amplifiers and radio vehicle mounts to a major international defense contractor for an ongoing allied country government/defense modernization program.

Cost of Products Sold / Gross Profit. Cost of products sold totaled $56,584 for the six-month period ended June 30, 2023, an increase of $8,689, or 18.1%, from the $47,895 reported for the same six-month period a year ago. Consolidated cost of products sold as a percentage of total revenue decreased from 76.6% for the six-month period ended June 30, 2022 to 75.8% for the six-month period ended June 30, 2023. Correspondingly, consolidated gross margin increased from 23.4% for the six-month period ended June 30, 2022, to 24.2% for the six-month period ended June 30, 2023, primarily reflecting higher factory volume and favorable product mix for our Communications Systems segment, tempered by the inefficiencies experienced at our Newark, NY and Virginia Beach, VA facilities resulting from the January 2023 cyberattack.

For our Battery & Energy Products segment, gross profit for the first six months of 2023 was $14,055, an increase of $183 or 1.3% over gross profit of $13,872 for the comparable 2022 period. Battery & Energy Products’ gross margin of 22.5% decreased by 90 basis points from the 23.4% gross margin for the year-earlier period, primarily reflecting lingering supply chain disruptions, inefficiencies resulting from the January 2023 cyberattack, disposition of certain non-conforming materials and continued investments in the transition of new products to high volume production, partially offset by improved price realization.

For our Communications Systems segment, gross profit for the first six months of 2023 was $3,969 or 32.3% of revenues, compared to gross profit of $732 or 22.8% of revenues, for the comparable 2022 period. The increase was primarily due to higher factory volume and favorable product mix compared to last year’s second quarter.

Operating Expenses. Operating expenses for the six-month period ended June 30, 2023 were $14,333, an increase of $227 or 1.6% from the $14,106 for the six-month period ended June 30, 2022. The increase is primarily attributable to increased new product development investments and the recording of the $100 deductible on our cybersecurity insurance policy for expenses incurred associated with the January 2023 cyberattack. Both periods reflected continued tight control over discretionary spending.

Overall, operating expenses as a percentage of revenues were 19.2% for the six-month period ended June 30, 2023 compared to 22.6% for the six-month period ended June 30, 2022. Amortization expense associated with intangible assets related to our acquisitions was $436 for the first six months of 2023 ($388 in selling, general and administrative expenses and $48 in research and development costs), compared with $651 for the first six months of 2022 ($600 in selling, general, and administrative expenses and $51 in research and development costs). Research and development costs were $3,810 for the six-month period ended June 30, 2023, an increase of $281 or 8.0%, from $3,529 for the six-months ended June 30, 2022. The increase is largely attributable to an increase in new product development in our Communications Systems business to pursue both government/defense major programs and commercial opportunities. Selling, general, and administrative expenses were essentially flat year over year, decreasing from $10,577 for the first six months of 2022 to $10,523 for the first six months of 2023, a decrease of $54 or 0.05%.

Other Income (Expense). Other income (expense) totaled $564 for the six-month period ended June 30, 2023 compared to ($232) for the six-month period ended June 30, 2022. Other income for the 2023 period includes an Employee Retention Credit for $1,544 under Section 2301 of the Coronavirus Aid, Relief and Economic Security Act which was filed with the Internal Revenue Service during the second quarter of 2023. Interest and financing expense increased $553, or 177.8%, from ($311) for the first six months of 2022 to ($864) for the comparable period in 2023. The increase is primarily due to the financing of our acquisition of Excell in December 2021, working capital funding resulting from our January 2023 cyberattack and rising interest rates. Excluding the ERC gain in the 2023 period, miscellaneous income (expense) amounted to ($116) for the 2023 period compared to $79 for the 2022 period, primarily attributable to foreign exchange gains and loss due to fluctuations in foreign currency exchange rates.

Income Taxes. The income tax provision for the 2023 six-month period was $1,242 compared to an income tax benefit of ($81) for the 2022 six-month period. Our effective tax rate increased to 29.2% for the 2023 period as compared to (30.5%) for the 2022 period, primarily attributable to the magnitude of our income reported in the first six-months of 2023, including the Employee Retention Credit, and the geographic mix of our operating results. The income tax provision for the first six months of 2023 is comprised of a $354 current provision for taxes expected to be paid on income primarily in foreign jurisdictions, representing a cash-based effective tax rate of 8.3%, and an $888 deferred tax provision which primarily represents non-cash charges for U.S. taxes that will be fully offset by net operating loss carryforwards and other tax credits for the foreseeable future. For the comparable 2022 period, the income tax benefit was comprised of a $294 current tax provision, representing a cash-based effective tax rate of 110.5%, and a ($375) deferred tax benefit. The period over period change in the cash-based effective tax rate is primarily attributable to the geographic mix of our operating results. See Note 6 to the consolidated financial statements in Item 1 of Part I of this Form 10-Q for additional information regarding our income taxes.

Net Income Attributable to Ultralife. Net income attributable to Ultralife was $2,994, or $0.19 per share – basic and diluted on a GAAP basis for the six-month period ended June 30, 2023, compared to $344, or $0.02 per share – basic and diluted, for the six-month period ended June 30, 2022. Adjusted EPS was $0.24 on a diluted basis for the 2023 period, compared to $0.00 for the 2022 period. Adjusted EPS excludes the provision (benefit) for deferred taxes of $888 and ($375) for the 2023 and 2022 periods, respectively, which primarily represents non-cash charges (benefits) for U.S. taxes that will be fully offset by net operating loss carryforwards and other tax credits for the foreseeable future. See the section “Adjusted EPS” on Page 23 for a reconciliation of adjusted EPS to EPS.

Weighted average shares outstanding used to compute diluted earnings per share decreased from 16,141,083 for the first six-months of 2022 to 16,140,528 for the first six-months of 2023. The decrease is attributable to stock option exercises since the second quarter of 2022 offset by a decrease in the average stock price used to compute diluted shares from $5.11 for the six-month period ended June 30, 2022 to $4.25 for the six-month period ended June 30, 2023. Accordingly diluted shares of 24,751 were added to basic weighted average shares in 2022 compared to 2,157 in 2023.

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 (loss) attributable to Ultralife before interest expense, provision (benefit) for income taxes, depreciation and amortization, and stock-based compensation expense, plus/minus expense/income that we do not consider reflective of our ongoing continuing operations. 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 (loss) attributable to Ultralife Corporation, 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 (loss). We believe that adjusted EBITDA permits a comparative assessment of our operating performance, relative to our performance based on our GAAP results, while eliminating 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 (loss), 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 (loss) attributable to Ultralife Corporation 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 loss attributable to Ultralife.

Adjusted EBITDA is calculated as follows for the periods presented:

Adjusted Earnings Per Share

In evaluating our business, we consider and use adjusted EPS, a non-GAAP financial measure, as a supplemental measure of our business performance. We define adjusted EPS as net income attributable to Ultralife Corporation excluding the provision (benefit) for deferred income 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 predominantly offset by our U.S. net operating loss 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 Corporation.

Adjusted EPS is calculated as follows for the periods presented:

	Three-Month Period Ended
	June 30, 2023						June 30, 2022
	Amount		Per Basic Share		Per Diluted Share		Amount		Per Basic Share		Per Diluted Share

Liquidity and Capital Resources

As of June 30, 2023, cash totaled $8,283 (including restricted cash of $81), an increase of $2,570 as compared to $5,713 of cash held at December 31, 2022, primarily attributable to draws on our credit facility and net income generated during the period.

During the six-month period ended June 30, 2023, cash provided by our operations was $386, as compared to $3,400 used in operations for the six-month period ended June 30, 2022. For the 2023 period, cash provided by our operations was comprised of net income of $3,013 plus non-cash items totaling $3,171 for depreciation, amortization, stock-based compensation, and deferred taxes, largely offset by a $5,798 increase in net working capital. The increase in working capital was driven by the procurement of inventory to proactively manage our supply chain, reduce lead times and the impact of potential cost increases on components and raw materials, and enhance our position to service customer orders, as well as the effects of the January 2023 cyberattack.

Cash used in investing activities for the six months ended June 30, 2023 was $1,013 for capital expenditures, primarily reflecting investments in equipment for new products transitioning to high-volume manufacturing.

Cash provided by financing activities for the six months ended June 30, 2023 was $3,362, largely attributable to draws on our credit facility primarily due to the sales impact of the January 2023 cyberattack as well as the advance purchase of certain critical raw materials, partially offset by principle payments on our term loan during the period.

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 June 30, 2023, the Company had $17,630 outstanding borrowings on the Revolving Credit Facility and $7,167 on the Term Loan Facility. The Company was in full compliance with all covenants under the Credit Facilities as of June 30, 2023.

As of June 30, 2023, we had made commitments to purchase approximately $1,023 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 to the consolidated financial statements in our 2022 Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q should be reviewed for a greater understanding of how our financial performance is recorded and reported.

During the first six months of 2023, 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.
