(Unaudited)

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, 2024.

The December 31, 2024 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

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” to expand the disclosure requirements for reportable segments. The standard expands reportable segment disclosure requirements for public business entities primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment operating profit (loss). This standard is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The adoption of this new accounting standard did not have an impact on the Company's results of operations, financial position or cash flows.

Recent Accounting Guidance Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topics 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for the Company’s annual reporting period beginning January 1, 2025, however, these disclosures are not required for interim periods. The amendments are to be applied on a prospective basis, although retrospective adoption is permitted. The Company is currently evaluating the impact that ASU 2023-09 will have on its consolidated financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03 “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” which requires public entities to disclose specified information about certain costs and expenses. ASU 2024-03 is effective for the Company’s annual reporting period beginning January 1, 2027 and interim reporting periods beginning January 1, 2028, with early adoption permitted. The Company is currently evaluating the impact that ASU 2024-03 will have on its consolidated financial statements.

On October 31, 2024, the Company completed the acquisition of all issued and outstanding shares of Electrochem Solutions, Inc., a Massachusetts corporation (“Electrochem”), pursuant to a stock purchase agreement (the “Agreement”) with Greatbatch Ltd., a New York corporation (the “Seller”), dated September 27, 2024 (the “Acquisition”). The Agreement established a purchase price of $50,000 for the Acquisition subject to customary working capital adjustments. The Company completed the Acquisition for $48,022 in cash, inclusive of working capital adjustment reductions of $1,978.

Based in Raynham, MA and with over forty years of battery technology experience in critical applications, Electrochem designs and manufactures primary lithium metal and ultracapacitor cells and battery packs serving energy, military and various environmental, industrial and utility end markets on a global basis. Acquiring Electrochem advances our strategy of more fully realizing the operating leverage of our business model through scale and manufacturing cost efficiencies. Electrochem brings a blue-chip customer base with little or no overlap with Ultralife’s customers, long-tenured technical resources which we plan to utilize in progressing our global new product initiatives, and a complimentary portfolio of highly engineered thionyl, sulfuryl and bromine chloride cells and packs which can be commercially cost prohibitive to substitute or switch out. We view this acquisition as an avenue to create highly attractive opportunities to drive revenue growth through heightened cross-selling platforms and extend our reach into underserved adjacent markets that demand uncompromised safety, service, reliability and quality. In addition, the combination of Electrochem and Ultralife creates achievable opportunities for gross margin expansion through the realization of vertical integration, supply chain synergies and lean initiatives. With Electrochem we are increasing our value to our customers and significantly strengthening our competitive position in our end markets.

The Company funded the purchase price for the Acquisition through the New Credit Agreement (refer to Note 3).

The Acquisition was accounted for in accordance with the accounting treatment of a business combination pursuant to FASB ASC Topic 805, “Business Combinations” (“ASC 805”). Accordingly, the purchase price was allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values on the acquisition date. The excess of the purchase price over the estimated fair value of the separately identifiable assets acquired and liabilities assumed was allocated to goodwill. Management is responsible for determining the acquisition date fair value of the assets acquired and liabilities assumed, which requires the use of various assumptions and judgments that are inherently subjective. The purchase price allocation presented below reflects all known information about the fair value of the assets acquired and liabilities assumed as of the acquisition date.

The goodwill included in the Company’s purchase price allocation presented above represents the value of Electrochem’s assembled and trained workforce, the incremental value that Electrochem engineering and technology will bring to the Company and the revenue growth which is expected to occur over time which is attributable to increased market penetration from future new products and customers. The goodwill acquired in connection with the acquisition is not deductible for income tax purposes.

Other intangible assets were valued using the income approach which requires a forecast of all expected future cash flows and the use of certain assumptions and estimates. The following table summarizes the estimated fair value and annual amortization for each of the identifiable intangible assets acquired.

We acquired right-of-use assets and assumed operating lease liabilities of $230. Right-of-use assets are classified as other noncurrent assets, and current and long-term lease liabilities are classified as accrued expenses and other current liabilities and other noncurrent liabilities, respectively, on the Company’s consolidated balance sheets.

The operating results and cash flows of Electrochem are reflected in the Company’s consolidated financial statements from the date of acquisition. Electrochem is included in the Battery & Energy Products segment.

For the three-month period ended September 30, 2025, Electrochem contributed revenue of $6,797 and net loss before income taxes of $251, inclusive, among other expenses, of amortization expense of $178 on acquired identifiable intangible assets and a $40 increase in cost of products sold for the fair value step-up of acquired finished goods inventory sold during the period.

For the nine-month period ended September 30, 2025, Electrochem contributed revenue of $23,718 and net income before income taxes of $2,118, inclusive, among other expenses, of amortization expense of $535 on acquired identifiable intangible assets, an $120 increase in cost of products sold for the fair value step-up of acquired finished goods inventory sold during the period, and a $54 increase in cost of products sold for one-time lean consulting costs.

During the three and nine-month periods ended September 30, 2025, the Company incurred transaction costs and other non-recurring expenses of $345 and $607, respectively, directly attributable to the acquisition, including accounting and consulting services. These costs are included in selling, general and administrative expense on the consolidated statement of income (loss) and comprehensive income (loss) for the three and nine-month periods ended September 30, 2025.

On October 31, 2024, Ultralife, SWE, CLB, Excell USA, and Electrochem, as borrowers, and certain other subsidiaries of the Company, entered into a new Credit and Security Agreement with KeyBank National Association (“KeyBank” or the “Bank”), as lender and administrative agent (the “New Credit Agreement”). The proceeds of the loans under the New Credit Agreement, were used, in part, to repay outstanding indebtedness under the Company’s Amended Credit Agreement.

The New Credit Agreement, among other things, provides in its term loan provisions for a 5-year, $55 million senior secured term loan (the “Term Loan” or “Term Loan Facility”). The Term Loan is subject to repayment in quarterly installments commencing March 31, 2025 in amounts as set forth in the New Credit Agreement. Interest is payable on the unpaid principal outstanding under the Term Loan. All amounts of unpaid principal and accrued and unpaid interest remaining due under the Term Loan are scheduled to be paid in full October 31, 2029.

Upon closing of the Acquisition on October 31, 2024 (see Note 2), the Company borrowed the full amount of the Term Loan Facility.

As of September 30, 2025, the Company had $50,937 outstanding principal on the Term Loan, $3,781 of which is included in current portion of long-term debt on the consolidated balance sheets, andno amounts outstanding on the Revolving Credit Facility. As of September 30, 2025, unamortized debt issuance costs associated with the Term Loan of $638 are classified on the consolidated balance sheets as a reduction of long-term debt, and unamortized debt issuance costs associated with the Revolving Credit Facility of $441 are classified on the consolidated balance sheets as other noncurrent assets. Debt issuance costs include lender fees and certain costs paid to third parties, including legal and accountant fees, and are amortized to interest expense over the term of the New Credit Agreement.

The New Credit Agreement also provides under its revolving credit provisions for revolving loans, letters of credit, and swing loans (“Revolving Credit Facility”). Upon the effectiveness of the New Credit Agreement, any amounts outstanding under letters of credit issued pursuant to the Amended Credit Agreement became issued under the New Credit Agreement. The availability under the Revolving Credit Facility is subject to certain borrowing base limits based on trade receivables and inventories. All unpaid principal and accrued and unpaid interest with respect to the Revolving Credit Facility is due and payable in full on October 31, 2029.

The Company may voluntarily prepay principal amounts outstanding under the New Credit Agreement at any time subject to certain advance notifications and other restrictions.

In addition to the customary affirmative and negative covenants, the Company must maintain a consolidated fixed charge coverage ratio, as defined in the New Credit Agreement, of equal to or greater than 1.15 to 1.00 for the fiscal quarter ending March 31, 2025, and for each fiscal quarter thereafter, as calculated for the four (4) consecutive fiscal quarters ending on such date, and a consolidated senior leverage ratio, as defined in the New Credit Agreement, not to exceed (i)3.50 to 1.00 for the fiscal quarters ending March 31, 2025 through December 31, 2025, (ii)3.25 to 1.00 for the fiscal quarters ending March 31, 2026 through December 31, 2026, (iii)3.00 to 1.00 for the fiscal quarter ending March 31, 2027 and on the last day of each fiscal quarter thereafter, for the remaining term of the New Credit Agreement. The Company was in full compliance with its covenants under the New Credit Agreement as of September 30, 2025.

Borrowings under the New Credit Agreement are secured by substantially all the assets of the Company and certain of its present and future subsidiaries who are or become parties to, or guarantors under the new Credit Agreement.

Interest will accrue on outstanding indebtedness under the Term Loan Facility and Revolving Credit Facilities at a variable rate of interest based on designated interest rate benchmarks plus a varying margin determined by reference to the consolidated senior leverage ratio in effect from time to time. Our borrowing rate was 6.62% as of September 30, 2025.

The Company must pay a fee of twenty, twenty-five or thirty basis points (depending on the consolidated senior leverage ratio in effect from time to time) based on the average daily unused availability under the Revolving Credit Facility.

The Company must make payments to the extent borrowings exceed the maximum amount then permitted to be borrowed 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.

Future minimum principal repayment obligations on our Amended Credit Facilities as of September 30, 2025 are as follows:

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 when the average market price exceeds the exercise price of the securities, if any, and is calculated using the treasury stock method.

For the three-month period ended September 30, 2025, there wereno outstanding awards included in the calculation of diluted weighted average shares outstanding and no potential common shares included in the calculation of diluted EPS, as no securities were dilutive. For the comparable three-month period ended September 30, 2024,864,854 outstanding stock options and 5,229 unvested restricted stock awards were included in the calculation of diluted weighted average shares outstanding, as such securities were dilutive, resulting in 249,082 potential common shares included in the calculation of diluted EPS. There were 384,124 outstanding stock options for the three-month period ended September 30, 2025, andno outstanding stock options for the comparable three-month period ended September 30, 2024, that were not included in the calculation of diluted weighted average shares outstanding as the effect would be anti-dilutive.

For the nine-month period ended September 30, 2025, there were 304,054 outstanding stock options and 34,819 unvested restricted stock awards included in the calculation of diluted weighted average shares outstanding, resulting in 60,915 potential common shares included in the calculation of diluted EPS. For the comparable nine-month period ended September 30, 2024, there were 786,854 outstanding stock options and 5,229 unvested restricted stock awards included in the calculation of diluted weighted average shares outstanding, resulting in 212,072 potential common shares included in the calculation of diluted EPS. There were 683,043 and 78,000 outstanding stock options for the nine-month periods ended September 30, 2025 and 2024, respectively, not included in the calculation of diluted weighted average shares outstanding as the effect would be anti-dilutive.

Fair Value Measurements and Disclosures

The fair value of financial instruments approximated their carrying values at September 30, 2025 and December 31, 2024. 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.

Inventories, Net

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:

Property, Plant and Equipment, Net

Major classes of property, plant and equipment consisted of the following:

Depreciation expense for property, plant and equipment was as follows:

Goodwill

The following table summarizes the goodwill activity by segment for the nine-month period ended September 30, 2025.

Other Intangible Assets, Net

The composition of other intangible assets was:

The change in the cost of total intangible assets from December 31, 2024 to September 30, 2025 is the effect of foreign currency translations.

Amortization expense for other intangible assets was as follows:

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

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 September 30, 2025, there was $542 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 nine-month period ended September 30, 2025:

Cash received from stock option exercises under our stock-based compensation plans for the three-month periods ended September 30, 2025 and 2024 was $37 and $24, respectively. Cash received from stock option exercises under our stock-based compensation plans for the nine-month periods ended September 30, 2025 and 2024 was $98 and $1,960, respectively.

Restricted stock awards vest in equal annual installments over three(3) years. Unrecognized compensation cost related to unvested restricted shares at September 30, 2025 and 2024, respectively, was $126 and $19.

Our effective tax rate for the nine-month periods ended September 30, 2025 and 2024 was 16.9% and 20.9%, respectively. The period-over-period change was primarily attributable to the geographic mix of our operating results.

As of December 31, 2024, we have domestic net operating loss (“NOL”) carryforwards of $15,000, which expire 2031 through 2035, and domestic tax credits of $3,200, which expire 2028 through 2044, available to reduce future taxable income. As of September 30, 2025, management has concluded it is more likely than not that these domestic NOL and credit carryforwards will be fully utilized.

As of September 30, 2025, for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately $9,600, 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 September 30, 2025, we havenot recognized a valuation allowance against our other foreign deferred tax assets, as realization is considered to be more likely than not.

As of September 30, 2025, 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 wereno unrecognized tax benefits related to uncertain tax positions at September 30, 2025 and December 31, 2024.

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 2021 thru 2023 remain subject to IRS examination. Our U.S. tax matters for 2001-2002, 2005-2007, 2009, 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 2014 thru 2023 remain subject to examination by various state and local tax jurisdictions. Our tax matters for the years 2014 thru 2023 remain subject to examination by the respective foreign tax jurisdiction authorities.

In July 2025, the One Big Beautiful Bill Act (the “Tax Act”) was enacted, introducing a series of corporate tax changes in the U.S., including 100% bonus depreciation on qualified property and full expensing for research and development expenditures. The impacts of the Tax Act are reflected in our results for the period ended September 30, 2025, and there was no material impact to our income tax expense or effective tax rate. Due to the existing net operating loss, we do not expect an impact on cash taxes paid in the current year, however certain provisions may change the timing of cash tax payments in future periods.

The Company has operating leases predominantly for operating facilities. As of September 30, 2025, the remaining lease terms on our operating leases range from approximately one (1) year to six (6) 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:

Supplemental cash flow information related to leases was as follows:

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

Future minimum lease payments as of September 30, 2025 are as follows:

Purchase Commitments

As of September 30, 2025, we have made commitments to purchase approximately $677 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 nine months of 2025 and 2024 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.

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 sheets. For the three-month and nine-month periods ended September 30, 2025, revenue recognized on extended warranties was $74 and $223, respectively.

As of September 30, 2025, there was deferred revenue on extended warranty contracts of $930, comprised of $298 expected to be recognized as revenue within one (1) year and classified as accrued expenses and other current liabilities on our consolidated balance sheets, and $632 expected to be recognized as revenue over the remaining duration of the respective contracts and classified as other noncurrent liabilities on our consolidated balance sheets.

As of December 31, 2024, there was deferred revenue on extended warranty contracts of $1,153, comprised of $298 expected to be recognized as revenue within one (1) year and classified as accrued expenses and other current liabilities on our consolidated balance sheets, and $855 expected to be recognized as revenue over the remaining duration of the respective contracts and classified as other noncurrent liabilities on our consolidated balance sheets.

As of September 30, 2025 and December 31, 2024, 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.

Operating segments represent a component of the Company that engages in business activities from which it may recognize revenues and incur expenses whose operating results are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. Once operating segments are identified, the Company determined which of those operating segments are required to be presented as reportable segments based on the quantitative thresholds.

We structure our operations primarily around the products we sell and report our financial results in the followingtwo reportable segments: Battery & Energy Products and Communications Systems. The Battery & Energy Products segment includes Lithium 9-volt, cylindrical and various 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.

Our CODM is Mike Manna, President & Chief Executive Officer. Both of our operating segments are regularly reviewed by the CODM through weekly revenue, gross margin and consolidated financial forecast updates, bi-weekly business and financial reviews to assess business performance, top priorities, utilization of resources and to regularly communicate with segment management, who are part of the CODM’s executive leadership team, and monthly meetings with the executive leadership team. In his role as CODM, Mr. Manna is deeply involved in business operations through daily updates by the segment management and ongoing financial, revenue and operations discussions.

The primary financial measures used by the CODM to monitor and evaluate the performance of the operating segments is segment contribution, as defined by gross profit less direct selling, general and administrative (“SG&A”) and research and development expenses. This metric is used as a consistent benchmark for comparison across reporting periods.

Corporate general and administrative (“G&A”) expenses, including costs associated with our acquisitions, include corporate functions including board of directors, executive officers, accounting & finance, human resources, legal, information technology and their related functional expenses. These costs are not directly allocable to the operating segments.

The CODM does not review segment assets at a level other than that presented in the Company’s consolidated balance sheets.
