Company Overview
Trasteel Holding S.A. describes itself as a “People Behind Steel” platform and, in the deal materials, as a European leader in steel trading and processing. It was formed in 2009, is headquartered in Lugano, Switzerland and Luxembourg, and operates in over 60 countries. The business is split roughly evenly between trading operations and industrial steel transformation, with trading covering steel and raw materials, steel-related consumables, non-ferrous metals, and energy trading. It also trades materials including alumina, silicon carbide, graphite, cassiterite, bauxite, copper, zinc, nickel, chromium, titanium, and tin.
On the industrial side, Trasteel says it owns 13 factories in 6 countries and sells to more than 4,000 customers worldwide. The operating model is straightforward: buy, move, process, and sell across the steel value chain. That makes the company more than a pure trader, but it also ties results to global industrial demand, logistics, and steel pricing. The deck frames the market as large and cyclical, with 2024 crude steel production of 1,885 million metric tons, finished steel consumption of 1,742 million metric tons, and exports of about 435 million metric tons. Construction is the biggest end market at 52% of demand.
The SPAC Deal
Trasteel is merging with Sizzle Acquisition Corp. II, which currently trades under the ticker SZZL. The transaction presentation says the deal implies a pro forma combined enterprise value of approximately $1.32 billion. Existing Trasteel shareholders will roll over 100% of their equity, so this is not a cash-out deal for the owners; it is a public listing event for the operating business.
The SPAC trust is the key retail variable. Sizzle II raised $230 million in its IPO, and its trust account held $230,000,000 as of March 31, 2026, or $10.39 per public share. That is the cash pool available to fund the merger, but it can shrink if shareholders redeem. No filing reviewed disclosed expected redemption levels for the Trasteel vote, and the presentation’s funding model assumes $230 million remains in trust, which is a 0% redemption assumption rather than a disclosed outcome. I did not find a disclosed PIPE or other committed outside financing, so the deal appears to rely on trust cash.
Dilution matters here. Sizzle II sold 23,000,000 public units at $10.00 each, and the sponsor plus Cantor bought 600,000 private placement units at $10.00 each, creating additional overhang. Public units include one public share and one public right, with each right converting into 1/10 of a Class A share upon a business combination. The 425 also says that at closing, public units split and rights convert into Class A shares, and all Class A shares are exchanged for Pubco ordinary shares. The combined company is expected to list on Nasdaq under TSTL. The deal was announced on April 13, 2026, and the company says closing is expected by the end of 2026, so the first trading window is most likely late 2026 if the vote and closing process stays on track.

The company says deal proceeds will be used for accretive strategic acquisitions and investments, working capital, and other general corporate purposes. For a business like Trasteel, the SPAC route can be faster than a traditional IPO and can provide a public currency for expansion across trading and industrial processing.
Another practical reason is that de-SPAC materials often allow management to present a fuller operating story than a standard IPO roadshow. Trasteel’s deck includes 2025 segment revenue, industrial throughput, and management financials, all of which help frame the scale of the platform. That said, the tradeoff is that SPAC investors must underwrite redemption risk, dilution from rights and private placement securities, and the possibility that the trust cash available at closing is materially lower than the headline $230 million.
Financial Highlights
Trasteel’s reported total revenues were $1.417 billion in 2023, $1.495 billion in 2024, and $1.821 billion in 2025. That implies growth of about 5.5% in 2024 and 21.8% in 2025 versus the prior year. The deck also breaks out 2025 revenue by segment: General Trading at about $621 million, Consumables at about $394 million, and Non-Ferrous at about $35.6 million, with industrial activities shown separately and processing about 800,000 metric tons per year.
On profitability, the presentation shows EBITDA of $137.8 million in 2023, $123.3 million in 2024, and $147.5 million in 2025. Cash and cash equivalents were $312.8 million in 2025, up from $261.8 million in 2024 and $222.7 million in 2023. The deck shows total assets of $1.184 billion, total liabilities of $987.4 million, and total equity of $196.5 million in 2025. These are management accounts based on Swiss GAAP FER and are not audited under IFRS/PCAOB. The presentation excerpts I found do not include explicit forward revenue or EBITDA projections.
Risk Factors
The biggest de-SPAC risk is redemption. Sizzle II’s trust held $230 million, or $10.39 per public share as of March 31, 2026, but that cash can leave if public shareholders redeem ahead of the vote. If redemptions are heavy, the company may have less cash than the deal presentation assumes, and the transaction economics can change quickly. There is also no disclosed PIPE in the materials reviewed, which makes trust retention even more important.
Dilution and execution risk are the other major issues. Public rights convert into shares, and the sponsor and Cantor already own private placement units, both of which add to the post-close share count. Trasteel shareholders are also subject to a 6-month lock-up after closing. Beyond the SPAC mechanics, the business itself is exposed to global steel cycles, construction demand, logistics, and cross-border execution across 60+ countries. The deal can still fail to close on time or at all, and the combined company must satisfy Nasdaq listing standards before it can trade as TSTL.
Comparable Public Companies
Trasteel’s closest public peers are metals and steel names with trading, processing, or distribution exposure. The most relevant comps are Ternium (TX), Cleveland-Cliffs (CLF), Steel Dynamics (STLD), Reliance (RS), and Ryerson (RYI). These are not perfect matches, but they help frame how the market values steel-cycle exposure versus service-center and processing businesses.
I did not pull live trading multiples in the source materials, so I am not assigning a current EV/EBITDA range here. In broad terms, the comp set spans integrated steel producers at lower-cycle multiples and distribution/processing names that can trade differently depending on margins, inventory turns, and the steel price backdrop. For retail investors, the key question is whether Trasteel deserves a producer-style multiple, a distributor-style multiple, or something in between given its split between trading and industrial transformation.

The setup is interesting because Trasteel is not a concept story; it is a real operating platform with $1.821 billion of 2025 revenue, $147.5 million of EBITDA, and a footprint across more than 60 countries. The deal also gives investors a cleaner way to underwrite a global steel trading and processing business than a typical IPO would, especially with the company’s segment detail and operating scale already laid out in the presentation.
What shareholders should watch now is simple: how much of the $230 million trust survives redemption, whether the deal stays on track without a disclosed PIPE, and how much dilution comes through from rights and private placement securities. The current SPAC ticker is SZZL, the expected post-merger ticker is TSTL, and the company says closing should happen by the end of 2026. If the trust cash holds up, the setup favors a meaningful public debut for a scaled industrial platform; if redemptions are heavy, the valuation case gets harder fast.
