What does Archimedes Tech SPAC Partners II do?
Archimedes Tech SPAC Partners II Co. is a Nasdaq-listed special purpose acquisition company rather than an operating technology business. Its securities trade under ATII for ordinary shares, ATIIU for units, and ATIIW for warrants. The company raised capital from public investors, placed most of that money in a trust account, and began searching for a private business to take public through a merger. Its official Nasdaq listing therefore represents a claim on trust cash, redemption rights, warrants, and a proposed transaction—not a mature stream of product revenue.
How is the SPAC structured?
The February 2025 IPO sold 23.0 million units at $10.00 each, including the underwriters’ 3.0 million-unit over-allotment. Each unit contained one ordinary share and one-half of one warrant; a whole warrant carries an $11.50 exercise price after a qualifying combination. A simultaneous private placement sold 840,000 units for $8.4 million. The trust initially received $231.15 million, or $10.05 per public unit. These terms, together with the sponsor economics and redemption mechanics, are detailed in the company’s 2025 Form 10-K.
| Element | Official terms | Analytical meaning |
|---|---|---|
| Public units | 23.0M units at $10.00, February 2025 | Created the cash pool and 23.0M redeemable public shares. |
| Public warrants | 11.5M warrants; $11.50 strike | Provide upside participation but can dilute the post-merger company. |
| Private units | 840,000 units for $8.4M | Funded transaction expenses and aligned the sponsor and underwriter with closing. |
| Target focus | AI, cloud services, automotive technology, and adjacent technology | Explains the eventual selection of advanced-materials company Forge Nano. |
Why ATII must be analyzed differently from an operating company
ATII had no operating revenue, customers, factories, or gross margin through March 31, 2026. Its value depends on trust cash, redemption rights, financing, and completion of an acceptable merger before the deadline.
How does ATII make money, and what does the latest quarter show?
ATII has no operating revenue before a merger. Its reported income comes mainly from interest on the trust account, while unrestricted cash pays legal, accounting, listing, diligence, and transaction costs. The latest filed snapshot is the quarter ended March 31, 2026. The first-quarter 2026 Form 10-Q shows positive interest-driven net income, declining cash outside the trust, and liabilities dominated by the deferred underwriting fee.
How did the quarter compare with the prior year?
| Metric | Q1 2026 | Q1 2025 | Interpretation |
|---|---|---|---|
| General and administrative expense | $448,673 | $157,451 | Higher transaction and public-company workload increased pre-closing cost. |
| Trust interest income | $2,141,962 | $1,305,884 | A larger fully funded trust and prevailing yields lifted non-operating income. |
| Net income | $1,704,803 | $1,159,223 | The increase was interest-driven, not evidence of product-market traction. |
| Operating cash used | $(208,688) | $(254,007) | Cash burn improved, but the company still consumed unrestricted liquidity. |
Why the balance-sheet composition matters
At March 31, 2026, total assets were $243.222 million, including $242.003 million in trust and $140,921 of prepaid expenses. Liabilities included $305,087 of accrued expenses, $4,283 due to a related party, and an $8.05 million deferred underwriting fee. The 23.0 million redeemable public shares carried an aggregate redemption balance of $242.003 million, equivalent to about $10.52 per share. Shareholders’ deficit was $7.141 million because redeemable shares are classified outside permanent equity. This presentation can look weak in isolation, but it is structural for a SPAC: the more important liquidity questions are unrestricted cash sufficiency, redemption levels, and access to transaction financing.

deal update
How did the Forge Nano transaction reshape the ATII story?
On April 20, 2026, ATII signed a business-combination agreement with Forge Nano, an advanced-materials and manufacturing-technology company. The announcement assigned Forge Nano a $1.2 billion pre-money equity valuation and contemplated a combined equity value of about $1.595 billion assuming no redemptions. The proposed company is expected to operate as Forge Nano and trade under NANO and NANOW after closing. The official transaction announcement transformed ATII from a broad technology acquisition vehicle into a financing and listing route for a capital-intensive battery and semiconductor platform.
Which turning points explain today’s transaction?
-
June 2024ATII formed as a Cayman Islands blank-check company with a technology mandate.
-
February 2025The $230M IPO and $8.4M private placement funded a $231.15M trust.
-
December 2025Pubco and merger subsidiaries were formed for a future business combination.
-
April 2026The Forge Nano agreement introduced a $1.2B pre-money valuation and $100M PIPE.
-
June 2026An amended Form S-4 and Samsung relationship advanced disclosure and industrial validation.
-
July 2026An additional $23M PIPE raised total commitments to $123M before the deadline.
What are the transaction economics?
The earnout links dilution to five-year share-price thresholds of $15, $20, and $25 or trailing-revenue thresholds of $400M, $600M, and $800M. These milestones show that the negotiated valuation assumes substantial future scale.
What changed in the latest financing update?
On July 14, 2026, the parties announced an additional $23 million PIPE, increasing total PIPE commitments to $123 million. Samsung SDI committed $20 million across a $10 million PIPE investment and a $10 million Forge Nano Series D investment. Forge Nano’s Series D closed at $97 million. Assuming no redemptions, the parties described more than $367 million of pro forma cash, comprising approximately $244 million in ATII trust cash and $123 million of PIPE commitments. The latest terms appear in the July 14, 2026 Form 8-K.
Why Forge Nano, and what business would ATII shareholders inherit?
Forge Nano applies atomic layer deposition and related surface engineering to semiconductor tools, battery products, and coating services. Closing would therefore convert ATII from a trust-backed shell into a capital-intensive advanced-manufacturing company.
How large is the commercialization plan?
The SEC-filed investor-presentation transcript describes more than 120 employees and roughly 200 patents, while management estimates an addressable market above $359 billion across the targeted applications. It also presents a 2025 revenue base of approximately $14.5 million and a 2027 target of $76 million, including $45 million from semiconductor equipment and $25 million from battery cells. These are company forecasts and strategic estimates, not audited assurances. The SEC-filed presentation transcript is useful because it exposes both the growth thesis and the execution gap investors must model.
| Management scenario | Operating assumption | Revenue indication | Research implication |
|---|---|---|---|
| Semiconductor base | 40 tools at about $1.5M each | About $60M | Commercial scale depends on bookings converting into installations and acceptance. |
| Semiconductor mid | 106 tools | About $185M | Requires manufacturing capacity, service capability, and repeat customer demand. |
| Battery facility base | 3 GWh at $150/kWh | About $399M | Revenue potential depends on utilization, qualification, price, and yield. |
| Combined Phase 2 | Equipment plus battery production | About $460M base; above $1.0B high case | These figures are long-range management scenarios and require substantial capital. |
Why the Samsung relationship matters
Forge Nano’s planned 3 GWh Morrisville, North Carolina battery facility is expected to require roughly $300 million to $330 million and has been associated with a $100 million U.S. Department of Energy grant. Samsung SDI’s investment, conditional procurement support, and authorized-distributor relationship add strategic validation and potential market access. The official Samsung SDI partnership announcement states that manufacturing is expected in 2028. The schedule highlights the valuation challenge: current capital must fund several years of construction, qualification, customer conversion, and production ramp before the facility can support mature cash flow.
Who owns ATII, and why does governance matter?
ATII uses one ordinary share, one vote, but influence is concentrated. The sponsor and leadership hold founder and private securities, while public shareholders hold redeemable shares and decide whether to remain invested through the merger.
Sponsor control and public-holder protections
| Holder or group | Reported stake | Source period | Why it matters |
|---|---|---|---|
| Archimedes Tech SPAC Sponsors II LLC / Long Long | 6.28M shares; 21.2% | 2025 Form 10-K ownership table | Founder and private securities create a strong incentive to close and influence the vote. |
| Directors and executive officers as a group | 6.28M shares; 21.2% | 2025 Form 10-K | Management’s economic exposure is concentrated in sponsor-related securities. |
| Tenor Capital Management | 1.50M shares; 5.1% | 2025 Form 10-K | A disclosed outside holder can affect meeting participation and redemption outcomes. |
| Public shareholders | 23.00M redeemable shares | March 31, 2026 | Each holder can vote and generally redeem for trust value, changing closing cash. |
Founder and private-placement holders waived redemption and liquidation rights for those securities and agreed to support a business combination, while public investors retain redemption rights. A public holder may not redeem more than 15% of the issued public shares without company consent. This structure can help prevent one holder from dominating redemptions, but it does not remove aggregate redemption risk. Sponsor shares are also subject to transfer restrictions, which defer liquidity but do not erase dilution.
How governance changes post-merger interpretation
After closing, ownership analysis shifts to the combined capitalization. Public shares, PIPE shares, sponsor securities, warrants, earnout shares, and possible contribution shares create several dilution layers, so basic and fully diluted share counts must be reconciled.
Which KPIs matter most for ATII?
Traditional revenue-growth and margin dashboards are not sufficient before the merger. The most informative ATII metrics track transaction certainty, cash availability, dilution, and the operating milestones of Forge Nano. A useful dashboard should separate pre-close SPAC indicators from post-close manufacturing indicators so that trust-account strength is not mistaken for operating-company strength.
Pre-closing SPAC dashboard
| KPI | Latest anchor | How to interpret it |
|---|---|---|
| Trust value per public share | About $10.52 at March 31, 2026 | Sets the approximate pre-vote redemption reference before taxes and permitted withdrawals. |
| Cash outside trust | $1.078M at March 31, 2026 | Measures capacity to fund filing, meeting, legal, and closing work without new support. |
| PIPE commitments | $123M announced July 14, 2026 | Reduces dependence on public trust cash and adds third-party validation. |
| Combination deadline | November 12, 2026 | Concentrates execution risk into a limited regulatory and shareholder timetable. |
| Redemption rate | Not yet disclosed for the merger vote | Directly determines cash delivered at closing and can alter financing needs. |
Post-closing operating dashboard
The KPI set changes by phase: redemptions and financing before closing; bookings, capex, and cash runway during the ramp; then utilization, margins, working capital, and free cash flow at scale.
What risks could change the outcome?
ATII combines deadline-driven SPAC risk with early-stage industrial execution risk. Failure to close by November 12, 2026 could lead to liquidation, while a completed merger would still face redemption, funding, manufacturing, and dilution pressure.
Closing, redemption, and dilution risks
| Risk | Financial line affected | Concrete watch item |
|---|---|---|
| High public redemptions | Cash delivered at closing | Redemption percentage and any replacement financing. |
| Missed deadline or failed conditions | Liquidation versus merger value | Registration effectiveness, shareholder meeting date, approvals, and closing timetable. |
| Warrant and earnout dilution | Fully diluted share count and per-share value | 11.92M ATII warrants, PIPE-linked warrants, sponsor securities, and up to $900M earnout value. |
| Unrestricted liquidity pressure | Pre-close cash runway | Cash outside trust, transaction expenses, and any sponsor working-capital loans. |
Forge Nano execution and capital-intensity risks
Forge Nano must move rapidly from a small revenue base to equipment scale and battery manufacturing. Orders can be delayed by qualification and acceptance, while plant economics depend on construction cost, yield, utilization, pricing, and customer demand.
Why does ATII matter for valuation?
ATII should be valued in layers: trust-backed redemption value, transaction optionality, and warrant exposure before closing; then Forge Nano’s operating cash flows and dilution after closing. A single deterministic DCF is fragile at this stage.
A practical pre-close valuation map
A pre-close model can begin with trust value and probability-weight the merger outcome. The $1.2B valuation is a negotiated input, while the announced $367M no-redemption cash figure is financing—not free cash flow—and must fund transaction costs, operations, and capex.
How a post-close DCF should be built
| DCF driver | Base evidence | Modeling treatment |
|---|---|---|
| Revenue ramp | 2025 base near $14.5M; management 2027 target $76M | Use staged probabilities for bookings, deliveries, qualification, and plant ramp. |
| Gross margin | Different economics across equipment, services, and batteries | Model segment margins separately rather than applying one blended mature margin immediately. |
| Reinvestment | 3 GWh facility budget of $300M–$330M | Link capex to construction milestones, capacity, utilization, depreciation, and funding needs. |
| Dilution | Public, private, PIPE, warrant, sponsor, and earnout securities | Reconcile fully diluted shares under share-price and performance scenarios. |
| Terminal risk | Early commercialization and concentrated project execution | Use a conservative terminal margin, return on capital, and discount rate until scale is demonstrated. |
Comparable analysis is difficult because Forge Nano spans semiconductor equipment, batteries, and advanced materials. Until segment disclosure matures, valuation should emphasize probability-weighted commercialization, cash runway, reinvestment, and fully diluted per-share value.
What is the key takeaway from ATII analysis?
Archimedes Tech SPAC Partners II bridges protected trust capital and a high-ambition industrial technology company. Pre-close statements demonstrate restricted liquidity, not operating performance; Forge Nano adds semiconductor, battery, patent, and manufacturing exposure.
The strongest anchors are the approximately $244M trust cited in July 2026, $123M of committed PIPE capital, Samsung SDI participation, and an experienced deal team. The main pressures are the November deadline, redemptions, dilution, a small revenue base, and a $300M–$330M battery-facility plan.
