AltStreet Analysis

·

Generated from EDGAR primary sources

Slate Infrastructure Fund LP is a Delaware limited partnership filing under Rule 506(b) and Section 3(c)(1), indicating a private pooled investment fund. This is an original pre-open filing with no capital raised or investor count disclosed at the time of submission. The fund is managed by Slate Infrastructure Fund GP LLC, with five executive officers listed: Peter Tsoulogiannis, Lisa Rowe, Jerry Cain, Jeff Rodgers, and Blair Welch.

This energy transition infrastructure fund uses the 506(b) exemption, which permits general solicitation restrictions typical of institutional private funds. Pre-open filings in infrastructure are common for establishing compliance posture before capital deployment; the absence of disclosed minimums and amounts on initial Form D is standard practice in this category.

Questions About Slate Infrastructure Fund LP

Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.

What is Slate Infrastructure Fund LP?

Slate Infrastructure Fund LP is a Delaware limited partnership that filed a Form D with the SEC on March 16, 2026 as a private equity fund. The filing claims Rule 506(b), Section 3(c), Section 3(c)(1), Section 3(c)(7) for an offering of equity and pooled investment fund interests. AltStreet links the issuer to Slate Infrastructure Fund LP.

Is Slate Infrastructure Fund LP legit?

AltStreet does not rate legitimacy; it reports the public record. Slate Infrastructure Fund LP filed a Form D with the SEC on March 16, 2026 claiming Rule 506(b), Section 3(c), Section 3(c)(1), Section 3(c)(7). A Form D is a notice of an exempt offering, not a review or approval of it. No sales had been reported as of that notice. AltStreet's enforcement record (SEC, FINRA and state actions) shows no action naming the issuer as of today. The issuer is linked to Slate Infrastructure Fund LP, which AltStreet has reviewed. Before investing, confirm the filing on EDGAR, check the seller's registration on FINRA BrokerCheck, and read the offering documents, which a Form D does not include.

Is Slate Infrastructure Fund LP registered with or approved by the SEC?

No. A Form D is a notice that an issuer is selling securities under an exemption from registration, and the SEC does not review, approve, or pass on the merits of the offering. The filing shows that Slate Infrastructure Fund LP claimed Rule 506(b), Section 3(c), Section 3(c)(1), Section 3(c)(7) and disclosed the items the form requires, such as the amount sold, the minimum investment, related persons, and anyone paid to sell the securities. It does not verify the issuer's claims or its business.

How much has Slate Infrastructure Fund LP raised?

Slate Infrastructure Fund LP reported that the first sale had not yet occurred as of the Form D filed March 16, 2026, so no amount sold or investor count is on file. The total offering amount is listed as indefinite.

Who can invest in Slate Infrastructure Fund LP?

The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. The filing checks both Section 3(c)(1), which caps the fund at 100 beneficial owners, and Section 3(c)(7), which requires every investor to be a qualified purchaser, generally an individual with at least $5 million in investments. A fund normally relies on one or the other. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated.

What is the minimum investment in Slate Infrastructure Fund LP?

The Form D lists the minimum investment as $0, which means the issuer did not state a minimum on the form. The offering documents, not the Form D, set the actual subscription terms.

Who is selling Slate Infrastructure Fund LP and how are they paid?

The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly. Sales commissions are reported as $0 and finders' fees as $0. Form D allows these to be estimates.

Who is behind Slate Infrastructure Fund LP?

The Form D lists 6 related persons: Slate Infrastructure Fund GP LLC, promoter (General Partner of the Issuer); Peter Tsoulogiannis, executive officer (Vice President of General Partner of Issuer); Lisa Rowe, executive officer (Vice President of General Partner of Issuer); Jerry Cain, executive officer (Vice President of General Partner of Issuer); Jeff Rodgers, executive officer (Vice President of General Partner of Issuer); Blair Welch, executive officer (President of General Partner of Issuer). Form D Item 3 requires executive officers, directors, and promoters of the issuer to be listed.

Where is Slate Infrastructure Fund LP located?

The issuer's address on its SEC filings is C/O Slate Asset Management, 150 N Wacker Dr., Suite 3100, Chicago, IL. Its phone number of record is (312) 847-1480. It is organized under the laws of Delaware.

How long is the Slate Infrastructure Fund LP offering open?

The issuer indicated that the offering is intended to last more than one year. An issuer must amend its Form D annually while a continuing offering stays open, and no amendment is on record yet.

How large is Slate Infrastructure Fund LP?

The issuer declined to disclose its revenue range on the Form D, which the form permits.
