Should You Buy InoBat Before the SPAC Merger Closes?
InoBat, a Slovakia-based battery company focused on automotive, aviation, UAV, and eVTOL applications, is being discussed in connection with a SPAC merger involving Cartesian Growth Corp II (ticker: REEUF). The setup could give InoBat a faster path to public markets, but investors should watch closely for redemption risk, dilution, and whether the deal is actually confirmed in the SEC record.

Deal at a Glance
SPAC partner: Cartesian Growth Corp II
SPAC ticker (trades now): REEUF
Deal status: Shareholder vote scheduled
Source filing: SEC 425 (2026-07-27)
Company Overview
InoBat describes itself as a battery company serving high-performance automotive and aviation markets, with a growing focus on UAV and eVTOL use cases. The company says its headquarters, R&D, and production center are in Voderady, Slovakia, and it entered the UAV/defense drone market in May 2025 with its E10 Cell, which it describes as Europe’s first homegrown battery for drones.
The company profile information available also says InoBat was founded in 2019 and is based in Bratislava, Slovakia. That puts it in a capital-intensive part of the battery supply chain, where scale, manufacturing execution, and customer qualification matter as much as product performance. The broader battery market is crowded and cyclical, with investors typically rewarding companies that can show commercial traction, manufacturing reliability, and a credible path to volume production.
The SPAC Deal
The only verified SEC record provided here is that Cartesian Growth Corp II filed a definitive proxy for an extraordinary general meeting on July 27, 2026 to approve an extension of its deadline to complete a business combination from August 5, 2026 to August 5, 2027. The SPAC trades today under REEUF. However, the filing trail supplied does not verify an InoBat merger agreement, so the deal should be treated as unconfirmed until an S-4, proxy, 8-K, or 425 explicitly ties InoBat to Cartesian Growth Corp II.
Because no merger agreement, valuation, PIPE, or post-merger ticker was disclosed in the materials provided, those key de-SPAC terms are not available here. What is known is that Cartesian Growth Corp II had $38,145,039 in trust as of March 31, 2026, plus $105,287 in operating cash, and a $5,611,464 working capital deficit. It also disclosed 4,173,618 Class A shares redeemed in connection with the prior extension vote, leaving $37,750,814.08 in trust immediately afterward. The sponsor also provided a $250,000 unsecured promissory note dated May 5, 2026, convertible into working capital warrants at the sponsor’s option upon closing. If a business combination is later confirmed, the first trading window would likely be shortly after shareholder approval and closing, but that timing cannot be pinned down from the current record.

If InoBat is in fact the target, the SPAC route would give it a faster path to public capital than a traditional IPO and could let management present long-range growth plans in the merger materials. That matters for a battery company, where commercialization timelines can be long and the market often wants to see a detailed roadmap before assigning value.
SPAC mergers also allow companies to market projections in the proxy materials, which can be useful for a business still scaling manufacturing and customer adoption. The tradeoff is that the structure can be more dilutive and more fragile than a standard IPO, especially if trust redemptions are heavy or if the deal needs extra financing to make the balance sheet workable at close.
Financial Highlights
No InoBat financial statements, revenue figures, or profit metrics were provided in the materials here, so the company’s current scale cannot be quantified from the disclosed record. Based on the company description alone, InoBat appears to be in a development-and-commercialization phase rather than a mature, cash-generating industrial business.
For Cartesian Growth Corp II, the balance sheet data are clear: $38.1 million in trust as of March 31, 2026, $105,287 in operating cash, and a $5.6 million working capital deficit. That trust balance is the main cash pool available to a target at closing, but the amount that survives depends on redemption levels. The sponsor loan suggests the SPAC needed extra working capital to keep the process moving, which is common late in a de-SPAC timeline but still a sign that cash management is tight.
Risk Factors
The biggest de-SPAC risk is that the transaction may not be fully confirmed in the public filing trail provided here. Even if an InoBat deal exists privately, investors should wait for the actual merger agreement, valuation, and closing conditions before assuming the combination will happen. If the deal is later announced, redemption risk will matter a lot: the more Class A holders redeem, the less cash remains from the trust and the more pressure falls on any outside financing.
Dilution is the other major issue. SPAC structures typically include sponsor promote economics and warrants, and this deal also includes a sponsor promissory note that can convert into working capital warrants at closing. That means the public float can be diluted before the combined company has proven its operating model. Shareholders should also watch for a deal-break if financing is not sufficient, and for the possibility that the trust cash is too thin after redemptions to support InoBat’s manufacturing and growth plans.
Comparable Public Companies
A reasonable peer set for InoBat includes QuantumScape (QS), Solid Power (SLDP), Microvast (MVST), and SES AI (SES). These names sit in the broader advanced battery and electrification bucket, where investors tend to focus on commercialization progress, customer validation, and cash burn rather than near-term earnings.
As a group, these comps have generally traded as high-volatility, story-driven stocks rather than steady industrial compounders. That matters because InoBat, if it comes public, will likely be judged against the same standard: how quickly it can turn product claims into repeatable revenue, and whether the market believes its technology can scale into real manufacturing economics.

Bottom line: the setup is interesting, but the current record does not yet prove that InoBat is actually the confirmed target of Cartesian Growth Corp II. Until the merger agreement and valuation are filed, the most important thing shareholders should watch is whether the company can move from an extension vote to a real transaction without excessive redemptions or financing gaps.
Why this matters now is simple: the SPAC has already burned time, has a modest trust balance relative to the needs of a battery manufacturer, and has shown signs of capital strain through the sponsor note and prior redemptions. If a deal is confirmed, the key question becomes whether the post-close cash stack and dilution profile still leave enough upside for public investors. If no deal is filed soon, the extension just buys time, not certainty.
