On January 28, 2026, the Registration Statement on Form S-1 ("the Registration Statement") filed with respect to our IPO was declared effective and on January 29, 2026, our stock began trading on the New York Stock Exchange (the "NYSE") under the ticker “YSS”. Refer to Note 1 – Description of Business and Basis of Presentation of the accompanying notes to the unaudited condensed consolidated financial statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional information.

Reworded

York is a leading, U.S.-based, national defense and commercial prime providing a comprehensive suite of mission-critical solutions for national security, government and commercial customers. York is one of the only space and defense primes with proprietary hardware and software capabilities designed to address customers’ complex mission requirements across the critical elements of the entire space ecosystem throughout the mission lifecycle. York is a partner of choice for our customers, with differentiated performance versus traditional primes based on price, speed to deployment, and sophistication of capabilities. For contracts which we have been awarded, our price per satellite has been approximately half the price per satellite of our competitors. We have also been the first to deliver and launch satellites for multiple PWSADoW programs. York is the first and only company to demonstrate Link-16 connectivity from space, highlighting our unique and innovative capabilities.

Reworded

York is purpose built to address evolving national security space challenges and to adapt to the ongoing shift in the U.S. government’s mission needs and procurement processes, where economics, agility, rapid capabilities, and heritage drive customer decision making. We deliver mission-critical solutions in a zero-tolerance for error environment where systems must work, and we believe we are well positioned to capturewin outsizedawards growthto successfully leverage production capabilities at scale in our core markets. York provides customers a vertically integrated, full technology stack of solutions including design, production, integration, and operation of spacecraft with turnkey offerings to manage spacecraft and constellations throughout their entire mission lifecycle. York has significant space heritage, having 74 missions with flight heritage, created 17 products with flight heritage, and logged over four million on-orbit hours. York’s position as a prime enables us to monetize the entire space vertical from launch to mission operations, from spacecraft to payloads, and from edge computing to data transfer.

Reworded

Our model allows us to capture recurring revenue driven by ongoing satellite-based software and services as well as hardware replacement cycles. Once spacecraft are fielded, we provide continuous operational support, downlinkground antennaterminal usage, and proprietary software solutions, including on-spacecraft upgrades during the full orbital lifespan. Contracts have historically provided a fixed cost for software maintenance with upgrade options available for purchase. The expected replacement cycle for the current portfolio of space vehicles is approximately five to six years. Our full lifecycle solution and ongoing operational support distinguishes us from our competitors, positioning us to act as prime for the replacement and potential expansion of competitors’ aging constellations. As a result, we expect our recurring revenue to increase as the installed base of spacecraft in orbit grows, creating a highly visible revenue model, accelerating growth and increasing margins.

Reworded

We have significant production capability and believe we will be able to meet demand to manufacture and test over 1,000 satellites annually, supporting our position as a leader in rapid, high volume spacecraft delivery. This investment in infrastructure and inventory is meant to create a durable competitive advantage, enabling us to capitalize on the rapidly growing space economy with the ability to reliably deliver spacecraft faster and more affordably than traditional primes.

Reworded

The increase in backlog as of MarchJune 31,30, 2026 compared to December 31, 2025 was primarily due to the execution of a new commercial contract during the period partially offset by revenue recognized during the period. We expect to recognize over 55% of our backlog as of MarchJune 31,30, 2026 as revenue within the next 12 months, and the balance thereafter.

Corporate Conversion and Common Control Reorganization

Removed

Prior to January 28, 2026, we operated as a Delaware limited liability company under the name Yellowstone Midco Holdings II, LLC (“Midco II”). On January 28, 2026, prior to the effectiveness of the Registration Statement, Midco II converted into a Delaware corporation pursuant to a statutory conversion and changed its name to York Space Systems Inc.

Removed

At the time of the Corporate Conversion, all units of Midco II were converted into shares of the Company's common stock, and immediately following the Corporate Conversion, Holdings distributed all shares of the Company's common stock received upon conversion of the common units of Midco II to its limited partners and liquidated. As a result of the Holdings Liquidation, all partners of Holdings, including investment funds managed by AE Industrial Partners, LP became direct holders of the Company's common stock.

New Commercial Contract

Removed

In February 2026, we executed a contract with a commercial customer for M-CLASS satellites from which we expect to generate revenue of approximately $187 million over the course of the contract.

Contract Award Outlook

Added

Through 2026, and increasingly into the second quarter of 2026, we have seen the U.S. Government transition from a linear constellation deployment approach to one where Indefinite Delivery, Indefinite Quantity contracts ("IDIQs") are awarded as on-boarding opportunities for large operational systems. We had previously expected Congress to pass a new budget resolution which we anticipated to have funding for new contract awards in several key areas where we have competitive advantages. However, we believe it is more likely for Congress to pass smaller program specific funding bills as well as continuing resolutions in order to incrementally fund existing programs. As a result, we, as well as other space primes, have not been awarded the large contracts that we expected in 2026, and instead have been awarded several IDIQs.

Added

We were awarded three IDIQ’s in the second quarter of 2026 and another in the third quarter and have been awarded two task orders against those IDIQs thus far. While these initial task orders are for less dollars than the contract awards we had expected to win earlier in the year, we believe these on-ramp task orders with these new classified customers will lead to more significant task orders in 2027.

Added

With the success of our Dragoon program, the SDA recently shifted priorities away from T1DES and has subsequently descoped the planned launch for the remaining T1DES constellation. The SDA has also indicated that it intends to make available hardware originally designated for T1DES to support other U.S. government priorities. While negotiations with us are ongoing regarding how this contract change will be implemented, we do not currently anticipate any material financial impact to our consolidated financials based on the terms of our effective contract with the SDA.

Reworded

To continue gaining market share and attracting customers, we plan to continue investing in our infrastructure to expand our production capabilities, including our satellite-based services, and to create a durable competitive advantage with the goal of enabling us to capitalize on the rapidly growing space economy. Our growth opportunity is dependent on our continued ability to expand our addressable market, winincluding but not limited to, space data network, space-based sensing and targeting, as well as Golden Dome missions, and to develop our portfolio of products and services related to our offerings. We intend to expand our operations and offerings significantly, but any difficulties in achieving or effectively managing our growth could have a negative effect on our operating results.

Reworded

We consider strategic acquisitions of businesses and other investments to expand our software and services footprint, deepen vertical integration, and accelerate entry into adjacent mission areas, with the goal of expanding our current portfolio and accessing new customers and technologies. We target companies that not only enhance our technical capabilities but also embed us more deeply into our customers’ mission workflows. By integrating strategic acquisitions with our strong internal execution, we aim to build a broader product and service offering with a goal of enhancing our growth and market share. We also may explore the divestiture of businesses that no longer meet our needs or strategy or that could perform better outside of our organization. These strategic transactions may beare costly, time consuming and challenging to consummate and/or integrate with our existing businesses, and may result in fluctuations in our operating results and financial position across periods that may be unrelated to our underlying performance. A portion of the consideration of the acquisitions we have completed recently has consisted of shares of our common stock, which dilute existing stockholders. Any particular acquisition or other investment we make could prove less successful than anticipatedanticipated, cause further stockholder dilution and have a negative effect on our business.

Comparison of the Six Months Ended June 30, 2026 to the Six Months Ended June 30, 2025

Added

The following table sets forth a summary of our unaudited condensed consolidated results of operations for the periods indicated, and the changes between periods.

Added

Net EAC Adjustments

Added

We record changes in costs estimated at completion (net EAC adjustments) using the cumulative catch-up method of accounting. Net EAC adjustments have in the past had, and may in the future have, a significant effect on reported revenues and gross profit. The table below presents the aggregate amounts for the following periods:

Added

Two contracts accounted for 60% and 28%, respectively, of the gross favorable EAC adjustment for the six months ended June 30, 2026 which were primarily due to lower‑than‑anticipated labor, materials, and subcontractor costs required to meet customer requirements in our sale of satellites. In contrast, two contracts accounted for 64% and 36% respectively, of the gross unfavorable EAC adjustment for the six months ended June 30, 2026, primarily due to additional unplanned labor, materials and subcontractor costs. Two contracts accounted for 49% and 33% of the gross unfavorable EAC adjustment for the six months ended June 30, 2025, due to additional unplanned labor, materials and subcontractor costs. Refer to Note 3 - Revenues of the accompanying notes to the unaudited condensed consolidated financial statements included in Item 1 of Part I in this Quarterly Report on Form 10-Q for additional information related to our net EAC adjustments.

The period-over-period increase in revenue was primarily driven by increases in progress towards completion and achievement of certain milestones and revenue generated from recently acquired businesses during the six months ended June 30, 2026, as compared to the six months ended June 30, 2025. These increases were partially offset by a decrease in progress as a significant project was completed during the six months ended June 30, 2026. The period-over-period increase in revenue was largely driven by existing contracts, with 55% of the revenue growth related to contracts that were already in place at June 30, 2025. Refer to Note 3 - Revenues of the accompanying notes to the unaudited condensed consolidated financial statements in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional information related to our net EAC adjustments.

The period-over-period increase in cost of revenues was primarily driven by increases of $5.9 million in direct labor related to larger contracts that have increased progress towards the design and build of satellites during the period. Other increases were attributed to depreciation and amortization of $4.0 million, other overhead costs of $3.7 million and the impact of the Company's acquisition activity partially offset by a decrease in direct materials and subcontractor costs of $5.0 million.

Added

Gross Profit

Added

Gross profit increased by $10.2 million, or 30%, to $44.3 million for the six months ended June 30, 2026, as compared to $34.1 million for the six months ended June 30, 2025. As a percentage of revenues, gross margin was 21% and 18% for the six months ended June 30, 2026 and 2025, respectively. The period-over-period increase in gross margin as a percentage of revenues was primarily attributed to lower unfavorable EAC adjustments during the six months ended June 30, 2026, as compared to the same period in 2025.

Added

Selling, General and Administrative (“SG&A”) Expenses

Added

SG&A expenses increased by $24.9 million, or 47%, to $77.5 million for the six months ended June 30, 2026, as compared to $52.6 million for the six months ended June 30, 2025.
