The Founding and Growth of Legence
Legence traces its roots back to 1963, when Joe and Nicki Parisi founded Therma Holdings, a company specializing in engineering solutions for buildings. Over the decades, the small firm evolved into a major player in infrastructure engineering and services. In 2020, the business was acquired by investment giant Blackstone and rebranded as Legence, reflecting its new focus on sustainability and decarbonization.
From the very beginning, Legence prioritized energy efficiency and institutional trust: it was among the first to provide integrated engineering solutions aimed at reducing the carbon footprint of buildings, delivering not only modernization but also significant cost savings on energy consumption. Today, Legence serves more than 5,900 clients, including over 60% of Nasdaq-100 companies, demonstrating the demand for its solutions at the highest corporate level.
The name Legence combines legacy and intelligence — symbolizing continuity and smart technologies. The company has built an architecture of “sustainability-driven engineering,” where buildings are equipped with advanced systems for heating, ventilation, power supply, and lighting that outperform traditional alternatives in efficiency and reliability.


In recent years, Legence has grown from a regional contractor into a national leader with a network of 70 offices across 20 states. Its team includes more than 1,200 engineers and 3,400 installation and service specialists, completing over 50,000 projects annually. The company’s portfolio features energy-efficiency projects for technology hubs, data centers, healthcare facilities, and industrial enterprises.
Today, Legence stands as one of the flagships of sustainable engineering in the U.S. The company is preparing for an IPO on Nasdaq with a target valuation of approximately $2.8 billion and plans to raise up to $702 million. For investors, this is a chance to participate in a business at the forefront of the low-carbon transition and setting the standards for the future of infrastructure. The IPO of Legence will serve as a key indicator of market demand for projects in energy efficiency and decarbonization.
Frequently Asked Questions (FAQ)
— What is an IPO?
An IPO (Initial Public Offering) is when a private company lists its shares on a stock exchange for the first time to raise capital from investors. From that point onward, the company’s shares can be freely bought and sold on the open market.
— Where are IPOs conducted?
IPOs take place on the world’s largest stock exchanges. In the U.S., the primary venues are the NYSE (New York Stock Exchange) and NASDAQ. Once a company goes public, its shares are freely traded on these exchanges, and the market price is established after the offering.
— What is allocation?
Allocation (from “allocation” — distribution) refers to the process of distributing resources, assets, or capital for maximum efficiency. In investing, allocation usually means distributing the available amount of shares among investors in an IPO or private placement.
— How much allocation does an investor receive?
The allocation size depends on the specific deal and typically ranges from 2% to 30% of the submitted order. Information about the actual allocation becomes available roughly one day before the offering, approximately six hours prior to the trade.
Example — Bullish IPO:
An investor placed an order for $10,000. The allocation was 29.6%, meaning $2,960 was invested in the IPO. The remaining $7,040, including the purchase commission, was refunded to the balance and became available for withdrawal.
— Why do companies go public?
To raise growth capital, increase brand visibility, and provide early investors and employees with an opportunity to sell part of their shares.
— How is participating in an IPO different from buying shares on the exchange?
When you participate in an IPO, you buy shares before they start trading publicly. This provides an opportunity to purchase at the fixed offering price but also carries the risk that the price may drop once trading begins.
— What do I get by participating in an IPO through Regolith?
You become an investor in the company at the IPO stage via our U.S. partner infrastructure. After the transaction is completed and the lock-up period expires, profits from the share sale are distributed among investors proportionally to their stake in the deal.
— What is a lock-up period and how long does it last?
A lock-up period is a timeframe set by the issuer and underwriters during which shares cannot be sold. For IPOs offered through our platform, this period is 93 days. Once it ends, the shares are sold on the exchange and proceeds are distributed among investors.
— How is participating through the platform different from buying shares independently?
To buy independently, you would need access to a U.S. broker, a significant investment amount, and approval from underwriters. The platform pools capital from investors, providing access to IPOs that are otherwise unavailable to most individuals.
— Through whom is IPO participation carried out?
We operate through a U.S.-based structure that works with a licensed broker in the U.S. Our partner selects promising IPOs and participates in the offering under its own name.
— How is the deal structured legally?
An investor signs an agreement/offer to participate in the investment product. Regolith then transfers funds to its partner entity — Wealthy Labs Limited (the provider), which enters into a forward contract with the broker and executes all operational activities. The provider delivers the financial outcome to Regolith, which then distributes proceeds among investors.
— Is there a minimum investment amount?
Yes. Each IPO has a defined minimum entry threshold, shown on the offering page. On average, Regolith provides access starting from $500.
— Do I receive shares into my personal brokerage account?
No. Shares are purchased and held in the partner’s brokerage account. After the lock-up period, the broker sells the shares and transfers proceeds for distribution among investors.
— Can shares be transferred directly to my brokerage account?
No. Participation is structured via a forward contract with the partner’s brokerage infrastructure. The deal is executed on behalf of the partner, and settlements with investors are carried out through the platform.
— How can I sell my shares after the IPO?
Sales are processed automatically: once the lock-up expires, the partner broker sells the shares on the exchange, and proceeds are distributed proportionally among investors.
— What are the risks of investing in IPOs?
IPOs are high-risk investments. While they may offer high returns, they also carry significant volatility. Share prices on the first trading day — and after the lock-up — can fluctuate sharply. There is a risk that the market price will fall below the offering price. In addition, macroeconomic and sector-specific factors can affect outcomes.
— Can I know in advance how much I will earn?
IPO returns are not guaranteed. The final result depends on the share price at the time of sale after the lock-up, overall market conditions, and the company’s performance.
— How can I verify that Regolith participates in IPOs?
We publish all available deal information in the client dashboard. Additionally, we provide an agreement disclosing the infrastructure used for transactions. Broker and partner documents are not shared, as they contain confidential data protected by contractual obligations.
