| Aggregators. The Management Members include Jeffrey Sprau, Stephen Butz, Gregory Barnes and Bryce Seki, in addition to other employees of Legence Parent. |

We and the selling stockholder have granted the underwriters a 30-dayoption to purchase up to additional shares of Class A Common Stock from us and additional shares of Class A Common Stock from the selling stockholder. We intend to contribute the net proceeds received from the sale of any additional shares by us to Legence Holdings in exchange for additional LGN Units being issued to Legence Sub, and Legence Holdings will use such net proceeds to purchase LGN Units, together with an equal number of shares of Class B Common Stock, from Aggregator I at a purchase price per LGN Unit and share of Class B Common Stock equal to the public offering price per share of Class A Common Stock in this offering, net of underwriting discounts and commissions. We will not receive any proceeds from the sale of additional shares by the selling stockholder. Offering Only Class A Common Stock will be sold to investors pursuant to this offering. Immediately following this offering, there will be shares of Class A Common Stock issued and outstanding and shares of Class A Common Stock reserved for exchanges of LGN Units (and the cancellation of the corresponding shares of Class B Common Stock pursuant to the Legence Holdings LLC Agreement). We estimate that our net proceeds from this offering, after deducting estimated underwriting discounts and commissions and other offering-related expenses, will be approximately $ million. We intend to contribute all of the net proceeds of this offering (not including the exercise of the underwriters’ option to purchase additional shares) to Legence Holdings in exchange for LGN Units. Legence Holdings intends to use approximately $ million for the repayment of outstanding borrowings under our Term Loan Credit Facility and the remaining proceeds for general corporate purposes. “Use of Proceeds” contains more information. As a result of the Corporate Reorganization and the offering described above (and prior to any exchanges of LGN Units):

 Stock (or      shares of Class A Common Stock if the underwriters exercise in full their option to purchase additional shares of Class A Common Stock); |
