Olympus Partners Sells $513 Million of Accelevation's IPO and Keeps 85% of the Votes
The data center supplier's $720 million Nasdaq listing sends at most $207 million gross to the company itself, and that slice goes first to buyout-era debt. Public buyers inherit the growth, 61% revenue concentration in two customers, and about one vote in eight.

A $720 million ask, mostly addressed to sellers
Accelevation launched its IPO roadshow on Tuesday: 30 million shares at $20 to $24, up to $720 million gross, Nasdaq ticker ACCV 1. The Miamisburg, Ohio maker of data-center power, cooling and white-space gear, founded in 2017 by Michael and Shawn Rubiera, wants a valuation of up to $5.37 billion 12. Investors have paid for this story all year, with data-center names Innio and Madison Air each raising more than $2.5 billion 1.
Accelevation's ask is the smallest of the year's data-center listings

Most of the money never reaches the factory
The filing splits the deal. Accelevation offers 8,635,165 shares; selling stockholders led by Olympus Partners offer 21,364,835, or 71% of it 34. Across the range, that works out to $427 million to $513 million gross for the sellers against $173 million to $207 million for the company. The prospectus says it in one line: Accelevation "will not receive any of the proceeds" from the sellers' shares 3.
The company's own net proceeds, about $180 million at the $22 midpoint, go to repay debt, cover offering costs and fund general corporate purposes 47. The credit agreement being repaid is dated 2 January 2025, the day Olympus bought the company 38. The underwriters' 30-day option covers 4.5 million more shares, every one from the sellers 34.
Sellers collect up to $513 million; Accelevation itself tops out at $207 million

| At $20 | At $24 | Change | |

| Company shares (8.6M) | $172.7M | $207.2M | +20.0% |
| Selling stockholders (21.4M) | $427.3M | $512.8M | +20.0% |
| Sellers' option (4.5M) | $90.0M | $108.0M | +20.0% |
What the new owners inherit
Olympus keeps about 85% of the voting power after listing, 83% if the option is exercised in full, leaving Accelevation a controlled company under Nasdaq rules 3. On the filing's counts, the 30 million shares on sale carry roughly 13% of the 223.6 million votes outstanding 37.
The business underneath is real but concentrated. First-half revenue of $437.5 million nearly tripled from $158.6 million a year earlier and swung to $18.8 million of net income, backlog sits near $1.1 billion, and two customers provided 61% of last year's direct revenue 13. The range top prices that at roughly six times annualized first-half revenue, and a tax receivable agreement with Olympus entities is expected to require "substantial" cash payments 3.
The bull case, and the test
The trajectory is genuine: revenue grew 147% in 2025 36, and Forgent Power Solutions, which raised $1.74 billion in its February debut, trades about 40% higher 12. Buyers are getting pickier about AI supply-chain names, weighing backlog quality and cash conversion over the label, said IPOX 25. The range is being read as a stress test of what the sector can still charge, in a fall market jolted by the first US rate hike in three years 25.
Watch the print
Pricing is expected in the week of 28 September 6. The tell is blunt: if the deal clears at $24 and the sellers' option is fully used, Olympus-led holders collect about $621 million, and the company that builds the data centers collects none of it 34.
