Executive Summary / Key Takeaways

• A Well-Armed Blank Check: OTG Acquisition Corp. I completed its $230 million IPO in September 2025, placing $231.15 million in trust and positioning itself as a well-capitalized player in the digital infrastructure SPAC space, with a broader mandate than many narrowly-focused competitors.

• The Clock Is Ticking: With a 24-month combination period that began in September 2025 and no target identified yet, OTGA faces intense time pressure to find and close a deal in a hyper-competitive acquisition environment where private equity and other SPACs are hunting the same assets.

• Sector Tailwinds Create Opportunity: The AI data center boom—projected to consume 9.1% of U.S. electricity by 2030—has created a rich pipeline of acquisition targets in power generation, digital infrastructure, and communications technology, exactly where OTGA's sponsor team has deep operational experience.

• Capital Advantage vs. Niche Rivals: OTGA's ~$231 million trust provides superior firepower compared to smaller, more specialized SPACs like AI Infrastructure Acquisition Corp. ($138M) and Bitcoin Infrastructure Acquisition Corp. ($100-150M), enabling pursuit of larger, more strategic targets.

• Critical Variables to Monitor: Investors should watch for target announcement timing (each month reduces runway), redemption rates (which could shrink the trust), and the sponsor's ability to leverage its infrastructure expertise to secure a deal before the deadline forces liquidation.

Setting the Scene: The SPAC That Aims to Power the AI Revolution

OTG Acquisition Corp. I is a Cayman Islands blank check company that completed its initial public offering on September 15, 2025, raising $230 million by selling 23 million units at $10 each. Unlike operating companies, OTGA generates no revenue and has no business operations—its sole purpose is to identify and acquire a target in the digital infrastructure services sector within 24 months. This structure means investors aren't buying a business; they're buying a management team's ability to find and execute a value-creating merger in a specific, high-growth vertical.

The company sits at the intersection of two powerful trends: the resurgence of SPACs as a viable public market entry path and the explosive demand for digital infrastructure driven by AI expansion. Data centers are projected to consume 9.1% of U.S. electricity by 2030, up from 4% today, while utility capital expenditure is forecast to grow from $174 billion in 2024 to $202 billion in 2025. This creates a target-rich environment of private companies needing capital to scale power generation, fiber networks, and compute infrastructure. OTGA's sponsor, OTG Acquisition Sponsor LLC, brings deep investment and operational experience in these exact sectors, which is the real asset investors are purchasing.

In the competitive landscape, OTGA faces direct rivalry from four primary SPACs that IPO'd in 2025: AI Infrastructure Acquisition Corp. (AIIA) with its narrow AI focus, Bitcoin Infrastructure Acquisition Corp. (BIXI) targeting crypto-related infrastructure, Republic Digital Acquisition Company (RDAG) with a broader digital economy mandate, and Thayer Ventures Acquisition Corporation II (TVAI) focusing on venture-stage tech. Each has raised between $100-200 million, making OTGA's $231 million trust a meaningful differentiator. Indirect competitors include private equity giants like Blackstone (BX) and DigitalBridge (DBRG), which have been aggressively acquiring digital infrastructure assets, potentially reducing the pool of available targets and inflating valuations.

Business Model & Strategy: Capital Deployment in a Seller's Market

OTGA's business model is straightforward yet execution-critical: preserve capital, identify an attractive target, negotiate favorable terms, and close a merger before the 24-month deadline expires. The company generates minimal non-operating income from interest on its trust account—$343,797 in the three months ended September 30, 2025—while incurring public company expenses of $119,427. This dynamic will persist until a business combination is consummated, at which point the acquired company's operations become the investment thesis.

The strategic focus on digital infrastructure services is deliberately broad, covering data centers, power generation, communication technology, and related ecosystems. This breadth provides flexibility that narrower SPACs lack. While AIIA is confined to AI-specific targets and BIXI to crypto-related infrastructure, OTGA can pursue opportunities across the entire value chain—from renewable power projects serving data centers to fiber optic networks to edge computing facilities. This flexibility becomes crucial in a competitive acquisition environment where specialization can become a strategic straitjacket.

The sponsor's experience, led by Scott Troeller with extensive infrastructure deal expertise, represents OTGA's primary intangible asset. In SPAC investing, you're betting on the sponsor's network, due diligence capability, and post-merger value creation skills. The sponsor's $25,000 investment for 5.75 million founder shares—now worth over $57.5 million at IPO price—creates powerful alignment, but also concentration risk. These founder shares will be worthless if no deal is completed, creating urgency, yet the sponsor's indemnification obligations for trust account shortfalls are backed only by its securities holdings, raising questions about its ability to satisfy claims if needed.

Financial Performance: The Pre-Combination Waiting Game

For the three months ended September 30, 2025, OTGA reported net income of $224,370, derived entirely from $343,797 in interest earned on marketable securities held in the trust account, offset by $119,427 in general and administrative costs. For the period from inception (June 12, 2025) through September 30, net income was $209,856 on $343,797 interest income and $133,941 in expenses. These figures are meaningless for evaluating business performance—they simply reflect the mechanics of holding IPO proceeds in trust.

What matters is the balance sheet and capital preservation. As of September 30, 2025, the company held $231.49 million in the trust account and reported total assets of $231.75 million. The working capital surplus of $46,435 appears precariously thin, but this is misleading. The sponsor had deposited the remaining $971,902 from the private placement subscription receivable on October 22, 2025, providing adequate working capital for the search process. Management asserts it has sufficient funds for one year of operations, which is standard SPAC practice but assumes the search process doesn't exceed budget.

Transaction costs from the IPO totaled $5.37 million, including a $4.60 million underwriting fee. The underwriters are due an additional $9.20 million cash fee upon consummation of the initial business combination, representing 4% of IPO gross proceeds. This fee structure aligns underwriter incentives with deal completion but also adds to acquisition costs. If no deal is completed, the underwriters receive no additional compensation, and the trust account is liquidated at approximately $10.05 per public share.

Competitive Positioning: Size and Scope as Strategic Weapons

OTGA's competitive advantages begin with its trust size. At $231.15 million, it can pursue targets too large for AIIA's $138 million trust or BIXI's estimated $100-150 million, but remains nimble enough to avoid the bureaucratic complexity that can plague larger SPACs. This mid-tier positioning is optimal for the digital infrastructure sector, where many attractive assets require $150-300 million in growth capital. The full exercise of the 3 million unit over-allotment option signals strong IPO demand, providing a psychological edge in negotiations with target companies.

The broader ecosystem focus creates a second advantage. While TVAI concentrates on venture-stage software and RDAG on general digital economy plays, OTGA can target integrated infrastructure assets that combine power generation with data center operations or communication networks with edge computing. This vertical integration potential appeals to sellers seeking strategic value beyond just capital. In a market where private equity firms are paying premium multiples for data center platforms, OTGA's ability to offer public market access plus strategic positioning in the power ecosystem can differentiate it from financial buyers.

However, OTGA faces significant competitive disadvantages. Its September 2025 IPO date means it started searching four to five months later than RDAG and TVAI, which IPO'd in May 2025. These early movers have had more time to build pipelines, conduct due diligence, and establish relationships with potential targets. In a 24-month race, a four-month head start is material. Additionally, OTGA lacks the specialized branding of AIIA (pure-play AI) or BIXI (crypto infrastructure), which can attract sellers specifically seeking partners with deep domain expertise in their niche.

The sponsor's network and execution track record must overcome these timing and branding deficits. While the competitive analysis suggests OTGA's team has superior infrastructure experience compared to AIIA's tech-focused sponsors or BIXI's crypto-native team, this advantage only materializes if it leads to a signed deal. The SPAC market's revival in 2025—with 107 IPOs through October—means more competition for fewer quality assets, increasing the risk of either overpaying or settling for a suboptimal target.

Risks and Asymmetries: Where the SPAC Structure Creates Tension

The most significant risk is time. With approximately 21 months remaining in the combination period, OTGA must identify, negotiate, and close a deal in an environment where due diligence on infrastructure assets can take 6-9 months. If the company fails to complete a business combination by September 2027, it will liquidate, returning trust funds at roughly $10.05 per share while the sponsor loses its entire $25,000 investment and $7.75 million private placement. This binary outcome creates urgency but also pressure to compromise on target quality.

Redemption risk compounds the time pressure. If a large portion of public shareholders redeem their shares at the business combination vote, the trust account could shrink substantially, leaving less capital for the target company. High redemption rates plagued SPACs in 2022-2023 and remain a threat, particularly if market conditions deteriorate or if investors view the announced target skeptically. AIIA and TVAI face identical risks, but OTGA's later IPO means it has less time to build investor confidence before the redemption decision point.

Target identification risk is acute. The company has not selected any specific business combination target and has not engaged in substantive discussions with any target. This "pure blind pool" status means investors have zero visibility into potential acquisition quality. While the sponsor's expertise provides some comfort, the digital infrastructure sector's rapid evolution means yesterday's expertise may not translate to tomorrow's best opportunities. The risk of overpaying for a data center operator at peak cycle valuations is real, especially with private equity competition driving up multiples.

Geopolitical and macroeconomic factors could derail the search. The company explicitly notes that Russia-Ukraine and Israel-Hamas conflicts create market volatility, supply chain disruptions, and increased cyberattack risks. Additionally, potential tariff changes—recalling the prior Trump administration's 10% baseline tariffs and up to 145% on China—could adversely affect target companies' operations and valuations. These factors are largely outside OTGA's control but could make sellers more reluctant to transact or buyers more cautious on valuation.

Valuation Context: Pricing a Promise, Not a Business

At $10.00 per share, OTGA trades exactly at its IPO price, reflecting the market's neutral assessment of its prospects pre-combination. The market capitalization of approximately $295 million includes both the 23.77 million public shares and the 5.75 million founder shares held by the sponsor. This structure means the public float is valued at roughly $238 million (23.77 million shares × $10.00), while the sponsor's stake represents the remaining equity value.

The trust account provides a hard floor for public shareholders. With $231.15 million held in trust representing $10.05 per public share, the downside is theoretically limited to a 0.5% gain from current levels if the company liquidates. This structure makes OTGA a risk-defined bet on the sponsor's ability to deliver a deal that justifies the opportunity cost of tying up capital for up to 24 months. The price-to-book ratio of 2000x is meaningless for a pre-combination SPAC and should be ignored; book value consists almost entirely of cash held in trust.

Comparing OTGA to its SPAC peers reveals similar valuation mechanics. AIIA trades near its $10.00 IPO price with a $191.55 million market cap and a similarly meaningless 4965x price-to-book ratio. RDAG shows a negative book value due to its structure, rendering its -33.12x ratio nonsensical. TVAI's -35.38x ratio tells the same story. For all these pre-combination SPACs, valuation metrics based on operating performance are irrelevant; the only meaningful metrics are trust value per share, time remaining, and sponsor quality.

The key valuation question is opportunity cost. With 10-year Treasuries yielding around 4%, investors earn minimal interest on the trust while waiting for a deal. The sponsor's $7.75 million private placement investment, purchased at $10.00 per unit alongside public investors, represents meaningful skin in the game. However, the sponsor's 5.75 million founder shares, acquired for just $25,000, create a potential misalignment if a suboptimal deal is pursued simply to avoid liquidation.

Conclusion: A Time-Sensitive Bet on Infrastructure Expertise

OTG Acquisition Corp. I offers investors a defined-risk vehicle to gain exposure to the AI infrastructure boom, with $231 million in trust and a sponsor team possessing deep sector expertise. The company's broader mandate and larger trust size provide competitive advantages over narrower, smaller SPACs targeting similar digital infrastructure assets. However, the September 2025 IPO date means OTGA started the race several months behind early movers like RDAG and TVAI, intensifying pressure to identify and close a deal within the remaining 21 months.

The central thesis hinges on whether the sponsor's network and due diligence capabilities can overcome the timing deficit to secure an attractive target before the deadline forces liquidation. Success would provide public market access to a company benefiting from data center power demand growth and utility capex expansion; failure means a 0.5% gain and capital returned. For investors, the critical variables are target announcement timing, redemption rates at the business combination vote, and the sponsor's ability to negotiate favorable terms in a competitive acquisition landscape. The digital infrastructure opportunity is real, but OTGA's window to capture it is rapidly narrowing.
