Organization, Consolidation and Presentation of Financial Statements [Abstract]

Segments

On February 27, 2026 (the “Closing Date”), the Company entered into a Securities Purchase Agreement with Event Risk LLC, an Indiana limited liability company (“Event Risk”) and a provider of security guarding, executive protection, investigations, and risk mitigation services operating throughout the United States, and Eric Rose (together with Event Risk, the “Seller”), pursuant to which the Company acquired all of the issued and outstanding membership interests of Event Risk (the “Acquired Interests”) for total purchase consideration of approximately $18.0 million (the “KSF Acquisition”). Event Risk operates as a wholly owned subsidiary of the Company doing business as Knightscope Security Force (“KSF” or “Security Force”).

Subsequent to March 31, 2026 and in connection with the integration of Security Force operations into the Company's broader Autonomous Security Force strategy, management, including the Company’s Chief Executive Officer who is its chief operating decision maker (“CODM,”) reassessed the Company's operating and reportable segments. As the Company has continued to combine its autonomous machines, orchestration software, and licensed armed and unarmed security agents into a single, integrated managed services offering, the CODM began reviewing consolidated operating results, including consolidated revenue and profitability measures, as one operating unit rather than two operating segments, which were previously identified as Core Technology Development and Operations and Acquired Security Force. Accordingly, effective for the quarter ended June 30, 2026, the Company determined that it operates as a single reportable segment, consistent with how the CODM allocates resources to, and assesses the performance of, the combined platform.

This change in reportable segments did not result from a divestiture, discontinuation, or other change in the underlying business, but rather reflects the evolution of the Company's internal reporting structure as KSF operations became increasingly integrated with the Company's core technology offerings, as contemplated at the time of the KSF Acquisition. The change did not affect the Company's previously reported consolidated financial results. The Company operates as a single reportable segment for the three months ended June 30, 2026 and thereafter. Prior period segment information has been recast to conform to the current presentation, where applicable.

All of the Company’s long-lived assets are located in the United States, and all of the Company’s revenue is derived from customers located in the United States.

Comprehensive Loss

Net loss was equal to comprehensive loss for the three and six months ended June 30, 2026 and 2025.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The Company places its cash and cash equivalents in highly liquid instruments with, and in the custody of, financial institutions with high credit ratings.

Inventory

Inventory, principally purchased components, is stated at the lower of cost or net realizable value. Cost is determined using an average cost, which approximates actual cost on a first-in, first-out basis. Inventory in excess of salable amounts and inventory which is considered obsolete based upon changes in existing technology is written off. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the new cost basis. The following table presents the components of inventory (in thousands):


	June 30,		December 31,
	2026		2025
Raw materials	$	2,528	$	2,051
Work in process		49		131
Finished goods		107		137
	$	2,684	$	2,319

Goodwill and Intangible Assets, net

The Company recorded goodwill of $1.9 million related to the Case Emergency Systems (“CASE”) acquisition completed in 2022. On February 27, 2026, the Company recorded goodwill of $7.7 million related to the KSF Acquisition. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any interim indicators of impairment. There was no impairment of goodwill during the six months ended June 30, 2026 and 2025.

The gross carrying amounts and accumulated amortization of the intangible assets with determinable lives are as follows (in thousands, except years):


		June 30, 2026
	Amortization	Gross
	Period	carrying		Accumulated		Carrying
Intangible assets with determinable lives	(years)	amount		amortization		amount, net
Developed technology	5	$	990	$	(734)	$	256
Customer relationships	6.7 - 8		16,450		(1,215)		15,235
Non-compete	5		570		(39)		531
Total		$	18,010	$	(1,988)	$	16,022


				December 31, 2025
		Amortization		Gross
		Period		carrying			Accumulated			Carrying
Intangible assets with determinable lives		(years)		amount			amortization			amount, net
Developed technology		5		$	990		$	(635)		$	355
Customer relationships		8			950			(381)			569
Total				$	1,940		$	(1,016)		$	924

Intangible assets amortization expense totaled $0.7 million and $0.1 million for the three months ended June 30, 2026 and 2025, respectively. Intangible assets amortization was recorded in sales, general and administrative and cost of revenue - service on the Company’s Condensed Consolidated Statements of Operations.

Intangible assets amortization expense totaled $1.0 million and $0.2 million for the six months ended June 30, 2026 and 2025, respectively. Intangible assets amortization was recorded in sales, general and administrative and cost of revenue - service on the Company’s Condensed Consolidated Statements of Operations.

As of June 30, 2026, future intangible assets amortization expense for each of the next five years and thereafter is as follows (in thousands):


Year ending December 31,		Amount
2026 (remaining six months)		$	1,377
2027			2,714
2028			2,557
2029			2,558
2030			2,534
2031 and thereafter			4,282
Total		$	16,022

Warranty Liability

The liability for estimated warranty claims is accrued at the time of sale, and the expense is recorded in the Condensed Consolidated Statements of Operations in cost of revenue - product. The liability is established using historical warranty claim experience. The current provision may be adjusted to take into account unusual or non-recurring events in the past or anticipated changes in future warranty claims. Adjustments to the warranty accrual are recorded if actual claim experience indicates that adjustments are necessary. Warranty reserves are reviewed to ensure critical assumptions are updated for known events that may impact the potential warranty liability.

Change in the warranty liability for the six months ended June 30, 2026 consisted of the following (in thousands):


		June 30,
		2026			2025
Balance January 1,		$	354		$	364
Provision for warranties issued			134			123
Warranty services provided			(206)			(125)
		$	282		$	362

Deferred revenue

In connection with the Company’s Machine-as-a-Service (“MaaS”) subscription for the Company’s ASRs, the Company’s standard billing terms are 1) annual in advance; 2) quarterly; or 3) monthly. In these situations, the Company records the invoices as deferred revenue and amortizes the subscription amount when the services are delivered, which generally is a 12-month period.

The Company derives its revenue from the lease subscription of its proprietary ASRs along with access to its browser and mobile based software interface, KSOC. MaaS subscription agreements typically have a 12-month term.

The Company also records deferred revenue from unfinished contracts for certain ECD and Security Force-related services.

Deferred revenue includes billings in excess of revenue recognized. Revenue recognized at a point in time generally does not result in significant increases in deferred revenue. Revenue recognized over a period generally results in a majority of the increases in deferred revenue as the performance obligations are fulfilled after the billing event. Deferred revenue was as follows (in thousands):


		Six Months Ended
		June 30,
		2026			2025
Deferred revenue, beginning of period		$	1,286		$	1,883
Revenue recognized in the six months ended related to amounts included in deferred revenue at the beginning of the period			(823)			(1,416)
Deferred revenue, KSF Acquisition			655			—
Revenue deferred, net of revenue recognized on contracts in the respective period			744			1,354
Deferred revenue, end of period		$	1,862		$	1,821

The Company expects the balance of deferred revenue to be recognized in the next 12 months.

Deferred revenue represents amounts invoiced to customers for contracts for which revenue has yet to be recognized based on subscription services to be delivered to the Company’s clients. Typically, the timing of invoicing is based on the terms of the contract.

Basic and Diluted Net Loss per Share

Net loss per share of common stock is computed using the two-class method required for participating securities based on their participation rights. All series of convertible preferred stock are participating securities as the holders are entitled to participate in common stock dividends with common stock on an as converted basis. The voting, dividend, liquidation and other rights and powers of the common stock are subject to and qualified by the rights, powers and preferences of any series of preferred stock as may be designated by the Company’s Board of Directors and outstanding from time to time. In accordance with the two-class method, earnings allocated to these participating securities, which include participation rights in undistributed earnings with common stock, are subtracted from net loss to determine net loss attributable to common stockholders upon their occurrence.

Basic net loss per share is computed by dividing net loss attributable to common stockholders (net adjusted for preferred stock dividends declared or accumulated) by the weighted average number of common shares outstanding during the period. All participating securities are excluded from basic weighted average shares outstanding. In computing diluted net loss attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by diluted weighted average shares outstanding, including potentially dilutive securities, unless anti-dilutive. Potentially dilutive securities that were excluded from the computation of diluted net loss per share for the three and six months ended June 30, 2026 and 2025 consist of the following:


		June 30,		June 30,
		2026		2025
Warrants to purchase common stock (convertible to Class A Common Stock)		186,411		186,411
Stock options		3,285,642		314,951
Total potentially dilutive shares		3,472,053		501,362

As all potentially dilutive securities are anti-dilutive as of June 30, 2026 and 2025, diluted net loss per common share is the same as basic net loss per common share for each period.
