Accelevation Targets a $4.9 Billion Valuation as Olympus Sells Into AI Infrastructure Demand

MIAMISBURG, Ohio, September 23, 2026

Accelevation Holdings is asking IPO investors to pay a growth multiple for a business sitting directly in the data-center construction rush, while most of the shares on offer come from existing owners. The Ohio manufacturer launched 30 million shares at $20 to $24, a $660 million deal at the midpoint that would value the company at about $4.9 billion. Only 8.6 million shares are being issued by Accelevation; selling stockholders are offering 21.4 million, or 71% of the base deal, according to the September 22 prospectus.

That split is the central fact in this IPO. Accelevation brings a compelling operating curve: revenue rose 147% to $447.8 million in 2025, then reached $437.5 million in the first half of 2026, up 176% from the prior-year period. Backlog stood at $1.11 billion on June 30. Yet the offering is also a substantial liquidity event for holders after Olympus Partners acquired control in early 2025. Renaissance Capital expects pricing during the week of September 28.

Fast growth, expensive capital

Accelevation designs, manufactures and installs the power distribution and white-space infrastructure inside hyperscale, colocation and AI data centers. Its portfolio ranges from remote power panels and distribution units to containment, thermal management and field installation. The company says it operates about 1.5 million square feet across Ohio, Virginia, Tennessee and Mississippi, with the vertically integrated design-to-install model presented on its corporate website.

The prospectus numbers show why the deal has attracted a top-tier bank group. Adjusted EBITDA was $90.9 million in 2025 and $68.4 million in the first six months of 2026. The six-month book-to-bill ratio was 2.5 times, and management says roughly $700 million of modular-solution bookings arrived in the nine months after that offering was first developed. Morgan Stanley and J.P. Morgan are representatives, with Goldman Sachs, Barclays and BofA Securities among the broader roster.

Cash conversion is the counterweight. Free cash flow was negative $16.4 million in 2025 and negative $15.8 million in the first half of 2026. Accelevation had $651.5 million outstanding under its term facility at June 30, carrying a weighted average rate of 8.772%. At the $22 midpoint, the issuer expects roughly $180 million of net proceeds before its offering expenses, substantially all of which is slated to repay borrowings. IPOGrid reads this as useful deleveraging, but not a balance-sheet reset: pro forma long-term debt remains about $464.5 million.

A concentrated bet on buildout cadence

The backlog gives the growth story visibility, though it is neither contracted revenue nor evenly diversified demand. One customer generated 35.2% of first-half 2026 revenue, and four disclosed major customers together represented 56.6%. In 2025, the two customers individually above the disclosure threshold supplied 61.2% of revenue. The reviewer’s concern is that a delay, redesign or purchasing pause at one hyperscale program can move results sharply even while the broader AI infrastructure market remains healthy.

There is also execution risk inside the growth itself. Revenue recognized over time reached $363.1 million in the first half, 83% of the total, as Accelevation handled more customized infrastructure contracts at higher values. These projects require estimates of progress and cost to complete. The company has expanded through acquisitions, including Aura Energy for $18.7 million and SteelPro for $43.5 million in 2025, while adding manufacturing capacity and launching newer products that now account for most of backlog. Our interpretation is that investors are underwriting rapid scaling across engineering, factories and job sites, not simply unit demand for standardized electrical equipment.

Public float, private control

The governance terms preserve sponsor control. The IPO uses an Up-C arrangement, and Olympus is expected to hold about 85% of combined voting power after the base offering, leaving Accelevation a Nasdaq controlled company. A tax receivable agreement will direct 85% of certain realized tax benefits to pre-IPO holders; the prospectus estimates an $82.5 million pro forma liability. Those terms are familiar in sponsor-backed flotations, but they matter when public investors are contributing fresh capital largely for debt reduction while insiders provide most of the stock sold.

At the midpoint valuation, the market is being asked to reward Accelevation’s rare combination of triple-digit growth, domestic manufacturing capacity and exposure to AI power density. The $1.11 billion backlog and deep underwriting bench give the book substance. The structure appears to us to leave less room for error: a mostly secondary sale, continued sponsor control, customer concentration and negative free cash flow all sit beside the growth. ACCV deserves attention because it offers one of the clearest public-market reads on the physical AI buildout. The pricing decision will show how much investors are willing to pay for that exposure when the sponsor is also heading for the exit window.
