Analysis: the clock, not the multiple, sets the terms

The hard constraint in this filing set is a date. Newbury Street II’s amended articles give it until November 4, 2026 to complete a business combination, and its own June 30, 2026 quarterly report calls that a mandatory liquidation date. The merger agreement’s outside date of May 17, 2027 therefore assumes something the merger agreement cannot deliver on its own, an extension approved by shareholders. Any extension vote is also a redemption event. That sequencing, rather than the headline valuation, is what a reader should track in the Form S-4 when it appears.

The trust is the second thing to watch. The quarterly report shows $185,070,108 held in trust at June 30, 2026, a redemption value of $10.73 per share on 17,250,000 public shares, up from $10.54 at December 31, 2025. Every no-redemption dollar is therefore worth more than the $10.00 at which PIPE shares are priced, and the Sponsor Letter Agreement provides for non-redemption arrangements to be incentivized in founder shares rather than in cash. The $201 million gross proceeds figure assumes no redemptions at all, an assumption the presentation itself flags as possibly not indicative of final redemption levels. BTIG’s deferred underwriting fee of $6,037,500 comes out of the trust only if the deal closes, and sits inside the $19.0 million of estimated transaction costs.

The disclosure establishes growth rates, margins and concentration for 2025 but not an absolute revenue figure, a cash position beyond a rolled-over net cash balance of $4.0 million at March 31, 2026, or any forward guidance that has been filed rather than presented. Percentage growth without a denominator is compatible with a wide range of businesses. The peer set the company selected for comparison consists of robotics companies with 2025 revenue below $100 million, which places an implied bound on the discussion but is not the same as a disclosed number. The registration statement will have to supply audited financials, and those, together with the redemption result at the extension vote, will determine whether the $556.6 million enterprise value survives contact with a shareholder vote.

What the documents say

Newbury Street II Acquisition Corp (Nasdaq: NTWO) signed an Agreement and Plan of Merger with Fort Robotics, Inc. on August 17, 2026, and disclosed the terms in a Form 8-K filed the following day. The blank check company will move out of the Cayman Islands and domesticate as a Delaware corporation before closing, a Delaware merger subsidiary will merge into Fort Robotics, and the surviving business will take the name FORT Robotics Holdings, Inc. The combined company is expected to trade on Nasdaq under the ticker FROB, subject to regulatory approvals. The announcement puts the pro forma enterprise value at $556.6 million against a pre-money equity value of $500.0 million.

Terms of the merger agreement

Fort Robotics security holders will receive shares of Newbury Street II common stock with an aggregate value of $500,000,000, each share valued at $10.00. Existing Fort Robotics shareholders roll all of their equity into the deal and are expected to hold about 67 percent of the issued and outstanding shares at closing on a no-redemption basis. The pro forma ownership table in the investor presentation splits the rest between Newbury Street II public shareholders at 21.3 percent, PIPE and non-redemption agreement holders at 5.9 percent, and the sponsor at 5.4 percent.

The post-closing board will have at least five and no more than seven members. Newbury Street II designates two, at least one of whom must qualify as independent under Nasdaq rules; Fort Robotics designates three, at least two of them independent; and the parties may agree on up to two more. Directors will serve staggered terms across three classes. The company said the expected board includes Sally Miller, global chief information officer at DHL Supply Chain, Jennifer Vescio, a former Uber executive, Vijay Kumar, dean of engineering at the University of Pennsylvania, and Karl Iagnemma, chief executive of Vecna Robotics.

Closing conditions include approval by both shareholder groups, expiry of the waiting period under the Hart-Scott-Rodino Act, an effective Form S-4 registration statement, conditional listing approval from Nasdaq or the New York Stock Exchange, and completion of the domestication. Either party may terminate if conditions are not met by an outside date of May 17, 2027, subject to extension if Newbury Street II wins more time to complete a business combination. The parties expect to close in the fourth quarter of 2026.

The financing package

Initial PIPE investors agreed to buy 3,125,000 shares at $10.00 for an aggregate $31.25 million, with an option to satisfy the commitment by buying shares in the market and not redeeming them at the shareholder meeting. The press release describes signed commitments of over $31 million of common equity split between PIPE and non-redemption agreements, and the presentation puts the pro forma enterprise value on an assumption of $15.8 million of PIPE investment and $15.5 million of non-redemption agreements. Investors named include Tiger Global, Prologis Ventures and Mark Cuban. Total gross transaction proceeds are put at roughly $201 million assuming no redemptions, leaving about $182 million of net cash on the balance sheet after estimated transaction costs of $19.0 million.

The sponsor carries much of the cost. Under the Sponsor Letter Agreement it forfeits 348,917 founder shares at closing, places 453,159 founder shares under an earnout, and must use up to 2,038,424 further founder shares to incentivize transaction financing investors or secure non-redemption arrangements. Any of those incentive shares still held at closing leave 302,110 subject to the same earnout. Up to 980,012 incentive founder shares transfer to the initial PIPE investors for no additional consideration. The earnout vests half at a volume weighted average price at or above $12.50 per share for 20 trading days in any 30 trading day window, and the balance at $15.00.

What FORT Robotics disclosed about the business

FORT Robotics was founded in 2018 and sells safety systems for autonomous machines under a platform it calls The Trust Layer. The company said the platform is backed by 25 patents, is certified to Safety Integrity Level 3 under IEC 61508, and is deliberately machine and application agnostic. More than 19,500 units are deployed to over 600 customers, a list the company says includes Agility Robotics, Google DeepMind, Zoox, Textron, Ocado and DoorDash. In May 2026 it acquired Mapless AI, a teleoperation company, adding remote human-in-the-loop control.

On the numbers the company chose to release, 2025 revenue grew 62 percent year over year while operating expenses grew 19 percent. Gross margin was 66 percent in 2025 against 70 percent in 2024. Revenue per employee was $276,000. Mature enterprise accounts, defined as customers spending more than $100,000 a year, grew 91 percent and increased per-account spend 27 percent. No single customer accounted for more than 9 percent of 2025 revenue, cohorts acquired before 2025 contributed an estimated 68 percent of 2025 bookings, and cumulative customers and deployed units have grown 2.6 times and 3.7 times respectively since 2021.
