Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

FormFactor reports that production at its Farmers Branch, Texas site began late in the third quarter, and its first customer shipment occurred in the fourth quarter. The site is still ramping toward target production levels through fiscal 2027; underutilization costs during the ramp are expected to weigh on gross profit and margin.

The restructuring is at different stages across the two sites: Baldwin Park manufactured through January 2026, while Carlsbad was expected to continue manufacturing through December 2026 as production shifts elsewhere.

As of September 26, 2026, cash, cash equivalents and marketable securities totaled $395.4 million, and no borrowings were outstanding under the $150 million revolving credit facility.

remaining performance obligations financial
"we had $13.3 million of remaining performance obligations"
Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.
cash flow hedge financial
"qualifies for, and is designated as, a cash flow hedge"
A cash flow hedge is an accounting label for a contract or arrangement used to offset expected future swings in a company’s cash payments or receipts — for example from variable-rate interest, foreign currency sales, or forecasted purchases. It matters to investors because it aims to smooth future cash and earnings volatility: gains or losses on the hedge are held out of current profit and reported separately until the underlying transaction affects results, much like buying insurance to steady future bills.
net contribution financial
"uses net contribution for each reportable segment"
SOFR financial
"forward-looking secured overnight financing rate (“SOFR”) term"
The Secured Overnight Financing Rate (SOFR) is a market benchmark that measures the cost of borrowing cash overnight using U.S. Treasury securities as collateral. Investors watch SOFR because it acts like a speedometer for short-term interest costs—affecting loan rates, bond yields and the pricing of interest-rate contracts—so movements change borrowing expenses, cash returns and the value of interest-sensitive investments.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1 — Basis of Presentation and Significant Accounting Policies
 
Basis of Presentation
The accompanying condensed consolidated financial information of FormFactor, Inc. is unaudited and has been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). However, such information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. The condensed consolidated financial statements included herein should be read in conjunction with the consolidated financial statements and the notes thereto included in our 2025 Annual Report on Form 10-K filed with the SEC on February 20, 2026. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
 
Fiscal Year 
We operate on a 52/53 week fiscal year, whereby the fiscal year ends on the last Saturday of December. Fiscal 2026 and 2025 each contain 52 weeks and the nine months ended September 26, 2026 and September 27, 2025 each contained 39 weeks. Fiscal 2026 will end on December 26, 2026.

Significant Accounting Policies
Our significant accounting policies have not changed during the nine months ended September 26, 2026 from those disclosed in our Annual Report on Form 10-K for the year ended December 27, 2025.

New Accounting Pronouncements
ASU 2024-03
In November 2024, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU requires an entity to disclose, in tabular format in the notes to the financial statements, specific information about certain costs and expenses. Although the ASU does not change the expense captions an entity presents on the face of the income statement, it requires disaggregation of certain expense captions into specified categories. The amendments in the ASU are effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. An entity may apply the amendments prospectively for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. This ASU will impact only our disclosures and not our financial condition and results of operations. We are currently evaluating the effect the adoption of this ASU may have on our disclosures.

Reclassifications
Certain immaterial reclassifications were made to prior-year amounts to conform to the current-year presentation. These reclassifications included presenting accrued restructuring charges separately from other accrued liabilities in Note 6, Accrued Liabilities. These reclassifications had no impact on previously reported results of operations, financial position, or cash flows.

Note 2 — Concentration of Credit and Other Risks

Each of the following customers accounted for 10% or more of our revenues for the periods indicated:

Note 4 — Acquisition

On December 15, 2025, we acquired 100% of the shares of Keystone Photonics for total consideration of $20.6 million, net of cash acquired of $1.7 million. Keystone Photonics provides optical probing technology used in the testing of silicon photonics (“SiPh”), co‑packaged optics (“CPO”), and near-packaged optics (“NPO”) devices. The acquisition expands the Company’s testing capabilities in these areas and supports customers as SiPh, CPO, and NPO technologies transition from development into high‑volume manufacturing, including applications related to artificial intelligence data-center infrastructure.

The acquisition was accounted for under the acquisition method of accounting, which requires that assets acquired and liabilities assumed be recognized on the consolidated balance sheets at their fair values as of the acquisition date. The purchase price was initially allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on management's estimates of their fair values as of the acquisition date, including goodwill representing the excess of consideration transferred over the fair value of identifiable net assets acquired. During the measurement period, the Company recorded adjustments to the purchase price allocation as additional information became available and certain valuation analyses were finalized. See Note 5, Goodwill and Intangible Assets, for information regarding changes to identifiable intangible assets and goodwill resulting from these adjustments. No portion of the goodwill is expected to be deductible for tax purposes.

The purchase price allocation was finalized during the second quarter of fiscal 2026. The table below summarizes the assets acquired, including goodwill and intangibles, and liabilities assumed as of December 15, 2025 (in thousands):

Note 7 — Restructuring Charges

On January 5, 2026, we adopted restructuring plans (the “2026 Restructuring Plans”) that are intended to better align our cost structure and support gross margin improvement to the Company’s target financial model, while also aligning manufacturing capabilities with current and anticipated business needs and the Company's strategic priorities. As part of this restructuring plan, the Company is consolidating the manufacturing facilities located in Carlsbad, California and Baldwin Park, California, to other manufacturing facilities.

The restructuring plans are expected to result in the Company recording restructuring charges in the aggregate amount of approximately $32.0 million to $40.0 million, estimated to be comprised primarily of $16.0 million to $18.5 million of costs related to the impairment and accelerated depreciation of property and equipment, $10.0 million to $12.5 million of costs relating to employee severance and benefits, $1.0 million to $2.0 million of impairment and accelerated amortization of right-of-use assets, and $5.0 million to $7.0 million of other costs. These restructuring charges relate primarily to the Company’s Probe Cards segment, and the Company expects the majority of charges to be incurred in fiscal 2026.

Total restructuring charges included in our Condensed Consolidated Statements of Income for the three and nine months ended September 26, 2026 were as follows (in thousands):

Note 8 — Debt

Revolving Credit Agreement
On July 29, 2025, we entered into a Revolving Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association, as Administrative Agent, and the lenders party thereto, providing us with a $150 million revolving credit facility (the “Facility”). The Facility has a maturity date of July 29, 2030. The Facility may be used for working capital and other
12


general corporate purposes, subject to the terms and conditions set forth in the Credit Agreement. No amounts were outstanding under the Facility as of September 26, 2026.

Borrowings under the Facility will bear interest at a fluctuating rate per annum equal to, at our option, (i) the forward-looking secured overnight financing rate (“SOFR”) term, (ii) a base rate set forth in the Credit Agreement, or (iii) a combination thereof, plus, in each case, an applicable margin calculated based on our leverage ratio. Voluntary prepayments are permissible without penalty, subject to certain conditions pertaining to minimum notice and minimum prepayment and reduction amounts as described in the Credit Agreement.

The Facility also bears a quarterly commitment fee ranging from 0.15% to 0.25% on the daily amount by which the commitments under the Facility exceed the outstanding amount. The commitment fee as of September 26, 2026 was 0.15%.

The Credit Agreement contains customary representations and warranties, and affirmative and negative covenants and events of default, including limitations on subsidiary indebtedness and liens, and the requirement to maintain specified financial ratios including the requirement to maintain a consolidated total net leverage ratio not exceeding 3.50 to 1.00 as of the last day of each fiscal quarter with an increase to 4.00 to 1.00 for four quarters following a permitted acquisition.

Building Term Loan and Interest Rate Swap
On June 22, 2020, we entered into an $18.0 million 15-year credit facility loan agreement (the “Building Term Loan”). The proceeds of the Building Term Loan were used to purchase a building adjacent to our leased facilities in Livermore, California. On May 19, 2023, we amended the Building Term Loan, replacing the benchmark reference rate London Interbank Offered Rate (“LIBOR”) with the term SOFR, with no change to the amount or timing of contractual cash flows.

The Building Term Loan bears interest at a rate equal to the applicable SOFR rate plus 1.86% per annum. Interest payments are payable in monthly installments over a fifteen-year period. The interest rate at September 26, 2026, before consideration of interest rate swap discussed in the next paragraph, was 5.55%. As of September 26, 2026, the balance outstanding pursuant to the Building Term Loan was $11.4 million.

On March 17, 2020, we entered into an interest rate swap agreement to hedge the interest payment on the Building Term Loan for the notional amount of $18.0 million, and an amortization period that matches the debt. As future levels of LIBOR over the life of the loan were uncertain, we entered into this interest-rate swap agreement to hedge the exposure in interest rate risks associated with movement in LIBOR rates. This agreement was amended on May 19, 2023 to replace the benchmark reference rate LIBOR with SOFR to match the Building Term Loan agreement (as amended). After the amendment, the interest rate swap continues to convert our floating-rate interest into a fixed-rate at 2.75%. As of September 26, 2026, the notional amount of the loan that is subject to this interest rate swap is $11.4 million.

Note 9 — Fair Value and Derivative Instruments

Whenever possible, the fair values of our financial assets and liabilities are determined using quoted market prices of identical securities or quoted market prices of similar securities from active markets. The three levels of inputs that may be used to measure fair value are as follows:
•Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving identical securities;
•Level 2 valuations utilize significant observable inputs, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
•Level 3 valuations utilize unobservable inputs to the valuation methodology and include our own data about assumptions market participants would use in pricing the asset or liability based on the best information available under the circumstances.

We did not have any transfers of assets or liabilities measured at fair value on a recurring basis to or from Level 1, Level 2 or Level 3 during the nine months ended September 26, 2026 or the year ended December 27, 2025.

The carrying values of Cash, Accounts receivable, net, Restricted cash, Prepaid expenses and other current assets, Accounts payable, and Accrued liabilities approximate fair value due to their short maturities. The carrying value of debt approximates fair value due to its variable interest rate.

No changes were made to our valuation techniques during the first nine months of fiscal 2026.

Cash Equivalents
The fair value of our cash equivalents is determined based on quoted market prices for similar or identical securities.

Marketable Securities
We classify our marketable securities as available-for-sale and value them utilizing a market approach. Our investments are priced by pricing vendors who provide observable inputs for their pricing without applying significant judgment. Broker pricing is used mainly when a quoted price is not available, the investment is not priced by our pricing vendors or when a broker price is more reflective of fair value. Our broker-priced investments are categorized as Level 2 investments because fair value is based on similar assets without applying significant judgments. In addition, all investments have a sufficient trading volume to demonstrate that the fair value is appropriate.

Unrealized gains and losses were immaterial and were recorded as a component of Accumulated other comprehensive loss in our Condensed Consolidated Balance Sheets. We did not have any other-than-temporary unrealized gains or losses at either
14


period end included in these financial statements.

Interest Rate Swap
The fair value of our interest rate swap contract is determined at the end of each reporting period based on valuation models that use interest rate yield curves as inputs. For accounting purposes, our interest rate swap contract qualifies for, and is designated as, a cash flow hedge. The hedged risk is the interest rate exposure to changes in interest payments attributable to changes in our variable-rate interest over the interest rate swap term. The changes in cash flows of the interest rate swap are expected to exactly offset changes in cash flows of the variable-rate debt. Cash settlements, in the form of cash payments or cash receipts, are recognized as a component of interest expense. The cash flows associated with the interest rate swaps are reported in Net cash provided by operating activities in our Condensed Consolidated Statements of Cash Flows and the fair value of the interest rate swap contracts are recorded within Prepaid expenses and other current assets and Other assets in our Condensed Consolidated Balance Sheets.

Foreign Exchange Derivative Contracts
We operate and sell our products in various global markets. As a result, we are exposed to changes in foreign currency exchange rates. We utilize foreign currency forward contracts to hedge against future movements in foreign exchange rates that affect certain existing foreign currency denominated assets and liabilities and forecasted foreign currency revenue and expense transactions. Under this program, our strategy is to have increases or decreases in our foreign currency exposures mitigated by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with foreign currency transaction gains or losses.

We do not use derivative financial instruments for speculative or trading purposes. For accounting purposes, certain of our foreign currency forward contracts are not designated as hedging instruments and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded within Other income (expense), net in our Condensed Consolidated Statement of Income for both realized and unrealized gains and losses. Certain of our foreign currency forward contracts are designated as cash flow hedges, and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded as a component of Accumulated other comprehensive loss and reclassified into earnings in the same period in which the hedged transaction affects earnings, and in the same line item on the Condensed Consolidated Statements of Income as the impact of the hedge transaction.

The fair value of our foreign exchange derivative contracts was determined based on current foreign currency exchange rates and forward points. All of our foreign exchange derivative contracts outstanding at September 26, 2026 will mature by the second quarter of fiscal 2027.

The following table provides information about our foreign currency forward contracts outstanding as of September 26, 2026 (in thousands):

Taiwan DollarSell141,237 4,450 

Our foreign currency contracts are classified within Level 2 of the fair value hierarchy as they are valued using pricing models that utilize observable market inputs.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis
We measure and report our non-financial assets such as Property, plant and equipment, Equity investment, Goodwill and Intangible assets at fair value on a non-recurring basis if we determine these assets to be impaired or in the period when we make a business acquisition. Other than as discussed in Note 4, Acquisition, there were no assets or liabilities measured at fair value on a nonrecurring basis during the three and nine months ended September 26, 2026 or September 27, 2025.

Note 10 — Warranty
We offer warranties on certain products and record a liability for the estimated future costs associated with warranty claims at the time revenue is recognized. The warranty liability is based upon historical experience and our estimate of the level of future
15


costs. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery costs. We regularly monitor product returns for warranty and maintain a reserve for the related expenses based upon our historical experience and any specifically identified failures. As we sell new products to our customers, we must exercise considerable judgment in estimating the expected failure rates. This estimating process is based on historical experience of similar products, as well as various other assumptions that we believe to be reasonable under the circumstances. We provide for the estimated cost of product warranties at the time revenue is recognized as a component of Cost of revenues in our Condensed Consolidated Statement of Income.

Changes in our warranty liability were as follows (in thousands):

Note 12 — Equity Investment

On February 21, 2025, Frontier Investments Co., Ltd (“HoldCo”), a joint holding company in which we hold a 20% share of the equity and an affiliate of MBK Partners holds an 80% share of the equity, through HoldCo’s wholly-owned subsidiary, FM Holdings Co., Ltd., acquired 100% of the shares of FICT Limited (“FICT”) from Advantage Partners Inc. Our initial $67.2 million equity investment comprised of the funding of our share of the purchase price of $59.6 million, subject to changes in foreign currency fluctuations, and acquisition costs of $7.5 million.

During the three and nine months ended September 26, 2026, we recorded income of $2.1 million and $5.9 million, respectively, from our equity share of the HoldCo using lag reporting. As of September 26, 2026, the carrying value of our investment was $70.5 million.

We engage in transactions with FICT, a related party and a supplier, in the normal course of business. Total related party purchases of inventory from FICT during the three and nine months ended September 26, 2026 was $4.1 million and $12.3 million, respectively.

Note 13 — Stockholders’ Equity and Stock-Based Compensation

Common Stock Repurchase Programs
On October 30, 2023, our Board of Directors authorized a two-year program to repurchase up to $75.0 million of outstanding common stock, with the primary purpose of offsetting potential dilution from issuance of common stock under our stock-based compensation programs. On March 29, 2025, our Board of Directors approved an increase to the repurchase program, authorizing the repurchase of an additional $1.6 million in shares of common stock. During the first fiscal quarter of 2025, we repurchased and retired 665,000 shares of common stock for $22.1 million, utilizing the remaining shares available for repurchase under the program.

On April 24, 2025, our Board of Directors authorized a new two-year program to repurchase up to $75.0 million of outstanding common stock to offset potential dilution from issuance of common stock under our stock-based compensation programs. This share repurchase program will expire on April 24, 2027. During fiscal 2025, we repurchased and retired 135,000 shares of common stock for $4.1 million. During the nine months ended September 26, 2026, we did not repurchase shares of common stock under this plan, and as of September 26, 2026, $70.9 million remained available for future repurchases.

Our policy related to repurchases of our common stock is to charge the excess of cost over par value to additional paid-in capital once the shares are retired. Share repurchases are subject to an excise tax enabled by the Inflation Reduction Act that is generally 1% of the fair market value of the shares repurchased at the time of the repurchase, net of the fair market value of certain new stock issuances during the same taxable year. Certain exceptions apply to the excise tax. The excise tax incurred, if applicable, is included in the cost of shares repurchased in the Condensed Consolidated Statement of Stockholders Equity. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

Restricted Stock Units

RSUs at September 26, 2026
1,406,487 59.35 

Performance Restricted Stock Units
We may grant Performance RSUs (“PRSUs”) to certain executives, which vest based upon us achieving certain market performance criteria.

On August 6, 2026, we granted 65,616 PRSUs to certain senior executives for a total grant date fair value of $11.3 million which will be recognized ratably over the requisite service period. The performance criteria are based on Total Shareholder Returns (“TSR”) for the period of July 1, 2026 - June 30, 2029, relative to the TSR of the companies identified as being part of the S&P Semiconductors Select Industry Index (FormFactor peer companies) as of the grant date.

Of the 172,680 PRSUs granted in 2023, 58,152 shares were forfeited during the requisite service period, resulting in 114,528 shares that were subject to the achievement of certain TSR performance criteria, assuming 100% achievement of such criteria. We achieved 200% TSR performance, which resulted in a total of 229,056 shares vested and issued in fiscal 2026 related to the fiscal 2023 PRSU grant.

PRSUs are included as part of the RSU activity above.

Note 15 — Commitments and Contingencies

Legal Matters
From time to time, we are subject to legal proceedings and claims in the ordinary course of business, the outcomes of which cannot be estimated with certainty. Our ability to estimate the outcomes may change in the near term and the effect of any such change could have a material adverse effect on our financial position, results of operations or cash flows.

Note 16 — Leases

We lease real estate space under non-cancelable operating lease agreements for commercial and industrial space, as well as for a portion of our corporate headquarters located in Livermore, California. Our leases have remaining terms of one to eight years, and some leases include options to extend up to 20 years. We did not include any of our renewal options in our lease terms for calculating our lease liability as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options at this time. The weighted-average remaining lease term for our operating leases was three years as of September 26, 2026 and the weighted-average discount rate was 5.3%.

Note 17 — Revenue

Transaction price allocated to the remaining performance obligations: On September 26, 2026, we had $13.3 million of remaining performance obligations, which were comprised of deferred service contracts, extended warranty contracts, and contracts with overtime revenue recognition that are not yet delivered. We expect to recognize approximately 37.4% of our remaining performance obligations as revenue in the remainder of fiscal 2026, approximately 57.6% in fiscal 2027, and approximately 5.0% in fiscal 2028 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.

Contract balances: The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable is recorded at the invoiced amount, net of an allowance for credit losses. A receivable is recognized in the period we deliver goods or provide services or when our right to consideration is unconditional. A contract asset is recorded when we have performed under the contract but our right to consideration is conditional on something other than the passage of time. Contract assets as of September 26, 2026 and December 27, 2025 were $3.2 million and $2.3 million, respectively, and are reported on the Condensed Consolidated Balance Sheets as a component of Prepaid expenses and other current assets.

Contract liabilities include payments received and payments due in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets at the end of each reporting period as a component of Deferred revenue and Other liabilities. Contract liabilities as of September 26, 2026 and December 27, 2025 were $37.3 million and $21.4 million, respectively. During the nine months ended September 26, 2026, we recognized $15.6 million of revenue that was included in contract liabilities as of December 27, 2025.

Costs to obtain a contract: We generally expense sales commissions when incurred as a component of Selling, general and administrative expense, as the amortization period is typically less than one year.

Revenue by category: Refer to Note 18, Operating Segments and Enterprise-Wide Information, for further details.

Note 18 — Operating Segments and Enterprise-Wide Information

We operate in two reportable segments consisting of the Probe Cards segment and the Systems segment.
19



Our chief operating decision maker (“CODM”) is our President and Chief Executive Officer, who assesses the reportable segments' performance by using each reportable segment's net contribution to make decisions about allocating resources and assessing performance for the entire company. The CODM uses net contribution for each reportable segment predominantly in the annual budget and forecasting process, as well as consideration of budget-to-actual variances on a quarterly basis when making decisions for assessment of our performance and results of operations. Certain components of net contribution are utilized to determine executive compensation along with other measures.

The following table provides net contribution by reportable segment and includes a reconciliation to net income before income taxes (dollars in thousands):

The following discussion and analysis should be read in conjunction with our condensed consolidated financial statements and the accompanying notes contained in this Quarterly Report on Form 10-Q. Unless expressly stated or the context otherwise requires, the terms “we,” “our,” “us” and “FormFactor” refer to FormFactor, Inc. and its subsidiaries.

Overview

FormFactor, Inc., headquartered in Livermore, California, is a leading provider of essential test and measurement technologies along the full semiconductor product lifecycle — from characterization, modeling, reliability, and design de-bug, to qualification and production test. We provide a broad range of high-performance probe cards, analytical probes, probe stations, thermal systems, and cryogenic systems to both semiconductor companies and scientific institutions. Our products provide electrical and optical information from a variety of semiconductor and electro-optical devices and integrated circuits from early research, through development, to high-volume production. Customers use our products and services to optimize device performance and advance yield learning.

We operate in two reportable segments consisting of the Probe Cards segment and the Systems segment. Sales of our probe cards and analytical probes are included in the Probe Cards segment, while sales of our probe stations, thermal systems and cryogenic systems are included in the Systems segment.

We generated net income of $150.4 million in the first nine months of fiscal 2026, compared to $31.1 million in the first nine months of fiscal 2025. The increase in net income was primarily attributable to higher revenues, with each quarter of fiscal 2026 achieving record quarterly revenue and surpassing the prior quarter's performance, as well as improved gross margins. These favorable factors were partially offset by higher restructuring charges associated with initiatives to better align our cost structure and support gross margin improvement.

Recent Developments

Tariff refunds — Beginning in 2025, the United States imposed additional tariffs on a wide range of imported products under various legal authorities, including the International Emergency Economic Powers Act (“IEEPA”). These tariffs were subsequently modified through incremental increases, decreases, pauses, and limited exemptions.

23


On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under IEEPA were not authorized by the statute. While the ruling did not establish a refund process, the U.S. Court of International Trade subsequently ordered U.S. Customs and Border Protection (“CBP”) to implement a process to administer refunds, which CBP began executing with the April 20, 2026 deployment of the Consolidated Administration and Processing of Entries (“CAPE”) system for certain IEEPA refund claims. We paid tariffs under IEEPA, and are following the established refund filing and validation process through the CAPE system, along with other importers seeking IEEPA refunds.

As of September 26, 2026, we received approximately $9.9 million in IEEPA refunds. While the majority of our anticipated IEEPA refunds have been received, we expect to receive an additional $1.8 million during the fourth quarter of fiscal 2026.

2026 Restructuring Plans — In January 2026, we adopted restructuring plans that are intended to better align cost structure and support gross margin improvement to our target financial model, while also aligning manufacturing capabilities with current and anticipated business needs and our strategic priorities. As part of this restructuring plan, we are consolidating the manufacturing facilities located in Carlsbad and Baldwin Park, California to other sites. The Baldwin Park site manufactured through January 2026 and the Carlsbad site is expected to manufacture through December 2026.

Factory Expansion — In June 2025, we purchased a manufacturing site in Farmers Branch, Texas. We commenced production at this site late in the third quarter of fiscal 2026, with the first customer shipment occurring in the fourth quarter of fiscal 2026. We expect production to continue ramping throughout fiscal 2027. The facility expands our manufacturing footprint and is expected to support incremental production capacity and a more favorable cost structure overall, once ramped to initial target production levels.

Critical Accounting Estimates

Management’s Discussion and Analysis and Note 2, Summary of Significant Accounting Policies, to the Consolidated Financial Statements in our 2025 Annual Report on Form 10-K describe the significant accounting estimates and significant accounting policies used in preparation of the Consolidated Financial Statements. Actual results in these areas could differ from management’s estimates. During the nine months ended September 26, 2026, there were no significant changes in our significant accounting policies or estimates from those reported in our Annual Report on Form 10-K for the year ended December 27, 2025.

Foundry & Logic — The increase in Foundry & Logic product revenues for the three and nine months ended September 26, 2026, compared to the three and nine months ended September 27, 2025, was driven by stronger probe-card demand for networking and server CPU designs.

DRAM — The increase in DRAM product revenues for the three months ended September 26, 2026, compared to the three months ended September 27, 2025, was primarily driven by increased demand for non-HBM DRAM designs, specifically DDR5. The increase in DRAM product revenues for the nine months ended September 26, 2026, compared to the nine months ended September 27, 2025, was driven by increased demand for high-bandwidth memory (“HBM”) designs utilized in generative artificial intelligence applications and higher demand for non-HBM DRAM designs, specifically DDR5.

Flash — The decrease in Flash product revenues for the three and nine months ended September 26, 2026, compared to the three and nine months ended September 27, 2025, was primarily driven by our strategic focus on other end markets and resulting reduced manufacturing activity for Flash products. A portion of Flash product revenues during the period was associated with manufacturing activity at our Baldwin Park manufacturing facility, which was closed in connection with our 2026 Restructuring Plans. As a result of this strategic focus and the expected growth of our other end markets, we expect Flash revenues to represent a smaller percentage of our overall revenue mix in future periods.

Systems — The increase in Systems market revenues for the three months ended September 26, 2026, compared to the three months ended September 27, 2025, was primarily driven by sales of Triton, our recently introduced high-volume photonics testing solution, with smaller increases in revenues from sales of cryogenic and thermal systems. The increase in Systems market revenues for the nine months ended September 26, 2026, compared to the nine months ended September 27, 2025, was also primarily driven by sales of Triton, with a smaller increase in revenues from sales of thermal subsystems, partially offset
25


by lower revenues from legacy product offerings as manufacturing capacity and customer demand increasingly shifted toward the Triton platform.

Geographic revenue information is based on the location to which we ship the product. For example, if a certain Taiwan customer purchases through its U.S. subsidiary and requests the products to be shipped to an address in Taiwan, this sale will be reflected in the revenue for Taiwan rather than the U.S.

Changes in revenues by geographic region for the three and nine months ended September 26, 2026, compared to the three and nine months ended September 27, 2025, were primarily attributable to changes in customer demand, product sales mix, and the timing of customer shipments and revenue recognition. Specifically, the changes in revenues by geographic region were attributable to the following:
•Taiwan — Increased demand for our Foundry & Logic and DRAM probe card products and increased demand for Triton, our recently introduced high-volume photonics testing platform within Systems, contributed to the increase in revenues.
•South Korea — Revenues for the three months ended September 26, 2026, were relatively consistent with the corresponding prior-year period, while stronger demand for certain DRAM probe card products, including those supporting HBM designs, earlier in the year contributed to higher revenues for the nine months ended September 26, 2026.

Cost of Revenues and Gross Margins
Cost of revenues consists primarily of manufacturing materials, compensation and benefits, shipping and handling costs, manufacturing-related overhead (including equipment costs, related occupancy, and computer services), warranty costs, inventory adjustments (including write-downs for inventory obsolescence), and amortization of certain intangible assets. Our manufacturing operations rely on a limited number of suppliers to provide key components and materials for our products, some of which are a sole source. We order materials and supplies based on backlog and forecasted customer orders. Tooling and setup costs related to changing manufacturing lots at our suppliers are also included in the cost of revenues. We expense all warranty costs, inventory provisions and amortization of certain intangible assets as cost of revenues.

We have been executing initiatives for gross margin improvements through operational effectiveness and financial discipline, including:
•Deploying our workforce and existing manufacturing footprint more effectively, which included the execution of our 2026 Restructuring Plans. During the three and nine months ended September 26, 2026, cost of revenues included $2.8 million and $28.6 million of restructuring costs, respectively, in connection with the 2026 Restructuring Plans.
•Driving improvement in manufacturing yields in key process areas, innovating to reduce manufacturing spending, and reducing cycle times in key manufacturing operations.

As explained further below in Factory Start-up Costs, we commenced production at our newly purchased manufacturing site in Farmers Branch, Texas late in the third quarter of fiscal 2026, with production expected to continue to ramp to initial target capacity throughout fiscal 2027. As production ramps, operating costs associated with the facility will largely be reflected in cost of revenues. During the period before the facility reaches its expected or normal utilization level, we expect certain
26


operating costs will not be absorbed into the cost of inventory. These underutilization costs will be expensed as incurred to cost of revenues and are expected to be substantial as we ramp the facility. As a result, we expect underutilization costs associated with the Farmers Branch facility to impact gross profit and gross margin during our ramp to initial target capacity.

Probe Cards — For the three and nine months ended September 26, 2026, gross profit and gross margins increased compared to the corresponding periods in the prior year, primarily due to increased revenue, favorable product mix, and higher factory utilization, including benefits from our gross margin improvement initiatives described earlier, as well as favorable impacts from IEEPA tariff refunds received during the third quarter of 2026. The tariff refunds increased Probe Cards gross profit by approximately $6.6 million and $7.4 million and gross margin by approximately 3.0 and 1.2 percentage points for the three and nine months ended September 26, 2026, respectively.

Systems — For the three and nine months ended September 26, 2026, gross profit and gross margins increased compared to the corresponding periods in the prior year, primarily due to increased revenue, favorable product mix, and favorable impacts from IEEPA tariff refunds received during the third quarter of 2026, partially offset by an increase in manufacturing spending. The tariff refunds increased Systems gross profit by approximately $2.0 million and gross margin by approximately 3.4 and 1.5 percentage points for the three and nine months ended September 26, 2026, respectively.

Corporate and Other — Corporate and Other includes unallocated expenses relating to restructuring charges, net, stock-based compensation expense, and amortization of intangible assets and fixed asset fair value adjustments due to acquisitions, which are not used in evaluating the results of, or in allocating resources to, our reportable segments. The increase in Corporate and Other costs for the three and nine months ended September 26, 2026, compared to the corresponding periods in the prior year, was primarily attributable to restructuring charges of $2.8 million and $28.6 million, respectively, incurred in connection with the 2026 Restructuring Plans.

Overall — Gross profit and gross margins fluctuate with revenue levels, product mix, selling prices, factory loading, material costs, and operational efficiencies. For the three and nine months ended September 26, 2026, compared to the corresponding periods in the prior year, gross profit and gross margins increased due to increased revenue, favorable product mix, higher factory utilization, and benefits from our gross margin improvement initiatives, including improved manufacturing yields, manufacturing spending innovation, and reduced cycle times, and favorable impacts from IEEPA tariff refunds received during the third quarter of 2026, partially offset by restructuring charges incurred in connection with the 2026 Restructuring Plans. The
27


tariff refunds related to tariffs incurred in prior periods and are not expected to provide a similar benefit in future periods. The tariff refunds increased gross profit by approximately $8.6 million and $9.4 million and gross margin by approximately 3.1 and 1.2 percentage points for the three and nine months ended September 26, 2026, respectively.

Research and development expenses increased for the three months ended September 26, 2026, compared to the corresponding period in the prior year, primarily due to higher general operating costs, mainly reflecting lower grant reimbursements, and higher performance-based compensation, partially offset by lower project material costs and lower stock-based compensation expense.

For the nine months ended September 26, 2026, research and development expenses increased compared to the corresponding prior-year period, primarily due to higher performance-based compensation, higher restructuring charges, including $1.3 million incurred in connection with the 2026 Restructuring Plans, and higher general operating costs. These increases were partially offset by lower project material costs and lower stock-based compensation expense.

Stock-based compensation expense was lower for the nine months ended September 26, 2026, primarily due to the reversal of previously recognized equity compensation expense resulting from the departure of our former Chief Financial Officer in the first quarter of fiscal 2026.

Factory start-up costs are costs associated with our newly purchased manufacturing site in Farmers Branch, Texas. The start-up costs consist of employee compensation costs, consulting costs, utilities, taxes and licenses, facility maintenance, and other expenses being incurred while the site is being brought to its intended use. These costs are expected to continue throughout the build-out, and will move to cost of revenues as the production ramps begin. We commenced production at this site late in the third quarter of fiscal 2026 with production to continue to ramp throughout fiscal 2027.

Interest income is earned on our cash, cash equivalents, restricted cash, and marketable securities. Interest income increased for the three and nine months ended September 26, 2026, compared to the corresponding period in the prior year, primarily due to higher average invested balances and interest income recognized on tariff refunds, partially offset by lower yields.

Interest expense primarily includes interest on our term loan, interest rate swap derivative contracts, commitment fee on our revolving credit facility, term loan issuance costs amortization charges, and our revolving credit facility issuance costs amortization charges. The interest expense for the three and nine months ended September 26, 2026 increased compared with the corresponding period in the prior year due to our entry into the revolving credit facility in the third quarter of fiscal 2025.

Other Income (Expense), Net
Other income (expense), net, primarily includes the effects of foreign currency and various other gains and losses. We partially mitigate our risks from currency movements by hedging certain balance sheet exposures, which minimizes the impacts during periods of foreign exchange volatility.

Provision for income taxes$13,114 $5,937 $20,239 $9,384 
Effective tax rate15.5 %29.1 %12.3 %21.9 %

Provision for income taxes reflects the tax provision on our operations in foreign and U.S. jurisdictions, offset by tax benefits from tax credits and the foreign-derived deduction eligible income (“FDDEI”) deduction. Our effective tax rate may vary from period to period based on changes in estimated taxable income or loss by jurisdiction, changes to the valuation allowance, changes to U.S. federal, state or foreign tax laws, changes in the benefit or expense related to stock-based compensation, future expansion into areas with varying country, state, and local income tax rates, and the deductibility of certain costs and expenses by jurisdiction. The decrease in our effective tax rate for the three and nine months ended September 26, 2026, compared to the corresponding periods in the prior year was primarily driven by changes in estimated taxable income by jurisdiction in the prior year and the prior-year impact of implementing tax law changes under the One Big Beautiful Bill Act, which did not recur in the current year.

Liquidity and Capital Resources

Capital Resources
Our working capital increased to $527.3 million at September 26, 2026, compared to $433.2 million at December 27, 2025.

Cash and cash equivalents primarily consist of deposits held at banks and money market funds. Marketable securities primarily consist of corporate bonds, U.S. treasuries, U.S. agency securities, and commercial paper. We typically invest in highly rated securities with low probabilities of default. Our investment policy requires investments to be rated single A or better, and limits the types of acceptable investments, issuer concentration and duration of the investment.

Our cash, cash equivalents and marketable securities totaled approximately $395.4 million at September 26, 2026, compared to $275.2 million at December 27, 2025. We have the full amount available under our $150 million revolving credit facility as of September 26, 2026. Based on our historical results of operations, we expect that our cash, cash equivalents, and marketable securities on hand, the cash we expect to generate from operations, and the available capacity under our revolving credit facility, will be sufficient to fund our short-term and long-term liquidity requirements primarily arising from: research and development, capital expenditures, including the Farmers Branch expansion, working capital, outstanding commitments, and other liquidity requirements associated with existing operations. However, we cannot be certain that our cash, cash equivalents, and marketable securities on hand, and cash generated from operations, will be available in the future to fund all of our capital and operating requirements. In addition, any future strategic investments and significant acquisitions may require additional cash and capital resources. To the extent necessary, we may consider entering into short and long-term debt obligations, raising cash through a stock issuance, or obtaining new financing facilities, which may not be available on terms favorable to us. If we are unable to obtain sufficient cash or capital to meet our needs on a timely basis and on favorable terms, our business and operations could be materially and adversely affected.

If we are unsuccessful in maintaining or growing our revenues, maintaining or reducing our cost structure, or increasing our available cash through debt or equity financings, our cash, cash equivalents and marketable securities may decline.

We utilize a variety of tax planning and financing strategies to manage our worldwide cash and deploy funds to locations where needed. As part of these strategies, we indefinitely reinvest a portion of our foreign earnings. Should we require additional capital in the United States, we may elect to repatriate indefinitely-reinvested foreign funds or raise capital in the United States.

Cash Flows
The following table sets forth our net cash flows from operating, investing and financing activities:

Net cash used in investing activities$(150,749)$(156,495)
Net cash used in financing activities$(25,375)$(9,560)

Operating Activities 
Net cash provided by operating activities consists of net income for the period, adjusted for certain non-cash items and changes in certain operating assets and liabilities. Net cash provided by operating activities for the nine months ended September 26, 2026 was attributable to net income of $150.4 million and net non-cash expenses of $77.5 million, partially offset by the increase in net working capital of $16.8 million. The cash used in net working capital was primarily driven by increased inventories of $30.2 million, increased accounts receivable, net, of $27.5 million, and decreased operating lease liabilities of $5.9 million, partially offset by increased deferred revenue of $15.9 million, increased other liabilities of $11.2 million, increased accrued liabilities of $9.5 million, and increased accounts payable of $9.3 million. The non-cash expenses mainly consisted of depreciation and amortization, stock-based compensation, non-cash restructuring, and the provision for excess and obsolete inventories.

Investing Activities
Net cash used in investing activities for the nine months ended September 26, 2026 primarily related to $87.2 million in net purchases of marketable securities and $64.4 million of property, plant and equipment purchases.

Financing Activities
Net cash used in financing activities for the nine months ended September 26, 2026 primarily related to $35.6 million used to pay tax withholdings for net share settlements of employee stock awards, partially offset by $11.1 million received from issuances of common stock under our employee stock purchase plan.

Debt

Revolving Credit Agreement
On July 29, 2025, we entered into a Revolving Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association, as Administrative Agent, and the lenders party thereto, providing us with a $150 million revolving credit facility (the “Facility”). The Facility has a maturity date of July 29, 2030. The Facility may be used for working capital and other general corporate purposes, subject to the terms and conditions set forth in the Credit Agreement. No amounts were outstanding under the Facility as of September 26, 2026.

Borrowings under the Facility will bear interest at a fluctuating rate per annum equal to, at our option, (i) the forward-looking secured overnight financing rate (“SOFR”) term, (ii) a base rate set forth in the Credit Agreement, or (iii) a combination thereof, plus, in each case, an applicable margin calculated based on our leverage ratio. Voluntary prepayments are permissible without penalty, subject to certain conditions pertaining to minimum notice and minimum prepayment and reduction amounts as described in the Credit Agreement.

The Facility also bears a quarterly commitment fee ranging from 0.15% to 0.25% on the daily amount by which the commitments under the Facility exceed the outstanding amount. The commitment fee as of September 26, 2026 was 0.15%.

The Credit Agreement contains customary representations and warranties, and affirmative and negative covenants and events of default, including limitations on subsidiary indebtedness and liens, and the requirement to maintain specified financial ratios including the requirement to maintain a consolidated total net leverage ratio not exceeding 3.50 to 1.00 as of the last day of each fiscal quarter with an increase to 4.00 to 1.00 for four quarters following a permitted acquisition. We were in compliance with the Facility's covenants as of September 26, 2026.

Building Term Loan and Interest Rate Swap
On June 22, 2020, we entered into an $18.0 million 15-year credit facility loan agreement (the “Building Term Loan”). The proceeds of the Building Term Loan were used to purchase a building adjacent to our leased facilities in Livermore, California.
32


On May 19, 2023, we amended the Building Term Loan, replacing the benchmark reference rate London Interbank Offered Rate (“LIBOR”) with the term SOFR, with no change to the amount or timing of contractual cash flows.

The Building Term Loan bears interest at a rate equal to the applicable SOFR rate plus 1.86% per annum. Interest payments are payable in monthly installments over a fifteen-year period. The interest rate at September 26, 2026, before consideration of interest rate swap discussed in the next paragraph, was 5.55%. As of September 26, 2026, the balance outstanding pursuant to the Building Term Loan was $11.4 million.

On March 17, 2020, we entered into an interest rate swap agreement to hedge the interest payment on the Building Term Loan for the notional amount of $18.0 million, and an amortization period that matches the debt. As future levels of LIBOR over the life of the loan were uncertain, we entered into this interest-rate swap agreement to hedge the exposure in interest rate risks associated with movement in LIBOR rates. This agreement was amended on May 19, 2023 to replace the benchmark reference rate LIBOR with SOFR to match the Building Term Loan agreement (as amended). After the amendment, the interest rate swap continues to convert our floating-rate interest into a fixed-rate at 2.75%. As of September 26, 2026, the notional amount of the loan that is subject to this interest rate swap is $11.4 million.

Stock Repurchase Programs

On October 30, 2023, our Board of Directors authorized a two-year program to repurchase up to $75.0 million of outstanding common stock, with the primary purpose of offsetting potential dilution from issuance of common stock under our stock-based compensation programs. On March 29, 2025, our Board of Directors approved an increase to the repurchase program, authorizing the repurchase of an additional $1.6 million in shares of common stock. During the first fiscal quarter of 2025, we repurchased and retired 665,000 shares of common stock for $22.1 million, utilizing the remaining shares available for repurchase under the program.

On April 24, 2025, our Board of Directors authorized a new two-year program to repurchase up to $75.0 million of outstanding common stock to offset potential dilution from issuance of common stock under our stock-based compensation programs. This share repurchase program will expire on April 24, 2027. During fiscal 2025, we repurchased and retired 135,000 shares of common stock for $4.1 million. During the nine months ended September 26, 2026, we did not repurchase shares of common stock under this program as we prioritized capital investments associated with the ramp of our Farmers Branch manufacturing facility. As of September 26, 2026, $70.9 million remained available for future repurchases.

(2) Represents our quarterly commitment fee of 0.15% on the daily amount by which the commitments under the Facility exceed the outstanding amount. This commitment assumes no borrowings.

The table above excludes our gross liability for unrecognized tax benefits and our deferred grant. The gross liability for unrecognized tax benefits was $55.4 million as of September 26, 2026. The timing of any payments which could result from these unrecognized tax benefits will depend upon a number of factors and, accordingly, the timing of payment cannot be estimated. The deferred grant was $18.0 million as of September 26, 2026, and consists of cash received from a California Competes Grant awarded from the California Governor's Office of Business and Economic Development. The timing of any potential repayments is dependent upon a number of factors, including the number of employees and capital investments within California over the 5-year term. Accordingly, the timing of any repayment cannot be estimated.

Off-Balance Sheet Arrangements
 
Historically, we have not participated in transactions that have generated relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of September 26, 2026, we were not involved in any such off-balance sheet arrangements.

Recent Accounting Standards

For a description of a recent change in accounting standards, including the expected dates of adoption and estimated effects, if any, in our condensed consolidated financial statements, see Note 1, Basis of Presentation and Significant Accounting Policies, in Part I, Item 1 of this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
 
For financial market risks related to changes in interest rates and foreign currency exchange rates, reference is made to Item 7A “Quantitative and Qualitative Disclosures about Market Risk” contained in Part II of our Annual Report on Form 10-K for the fiscal year ended December 27, 2025. Our exposure to market risk has not changed materially since December 27, 2025.

Item 4. Controls and Procedures
 
Evaluation of Disclosure Controls and Procedures
 
Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting
 
There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls
 
Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems’ objectives are being met. Further, the design of any control systems must reflect the fact that there are resource constraints, and the benefits of all controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of a simple error or mistake. Control systems can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

CEO and CFO Certifications
 
We have attached as exhibits to this Quarterly Report on Form 10-Q the certifications of our Chief Executive Officer and Chief Financial Officer, which are required in accordance with the Exchange Act. We recommend that this Item 4 be read in conjunction with the certifications for a more complete understanding of the subject matter presented.

PART II - OTHER INFORMATION
 
Item 1A. Risk Factors

There have been no material changes during the three months ended September 26, 2026 to the risk factors discussed in our Annual Report on Form 10-K for the year ended December 27, 2025. If any of the identified risks actually occur, our business, financial condition and results of operations could suffer. The trading price of our common stock could decline and you may lose all or part of your investment in our common stock. The risks and uncertainties described in our Annual Report on Form 10-K for the year ended December 27, 2025 are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.

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

Repurchase of Common Stock

We did not repurchase any shares of our common stock during the third quarter of fiscal 2026.

Item 5. Other Information

Rule 10b5-1 Trading Arrangements

During the quarter ended September 26, 2026, no director or officer of the Company adopted, modified, or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” as each term is defined in Item 408(a) of Regulation S-K, except as follows:

On September 1, 2026, Aric McKinnis, the Company's Chief Financial Officer, adopted a Rule 10b5-1 trading arrangement. Under this arrangement, a total of up to 3,600 shares of our common stock may be sold, subject to certain conditions, after December 8, 2026 and before the arrangement expires on November 12, 2027.

The above arrangement is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) of the Exchange Act.
