Morgan,Jefferies, Mizuho, Scotiabank, Stifel and Truist, as forward sellers (each, in its capacity as agent for its affiliated forward purchaser, a“Forward Seller” and, collectively, the “Forward Sellers”), relating to the offer and sale of shares of our Class A common stock, $0.01par value (“Class A common stock”), offered by this prospectus supplement and the accompanying prospectus, having an aggregateoffering price of up to $300,000,000 from time to time through the sales agents, through the Forward Sellers, acting as sales agents forthe relevant Forward Purchasers, or directly to one or more of the sales agents, acting as principal. Upon entering into the salesagreements, we simultaneously terminated the sale agreements relating to our prior at-the-market offering program established inNovember 2022. Our Class A common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “PSTL.” The last reported saleprice of our Class A common stock on the NYSE on August 4, 2026 was $23.11 per share. Sales of shares of our Class A common stock, if any, as contemplated by this prospectus supplement made through the sales agents orthe Forward Sellers will be made by means of ordinary brokers’ transactions on the NYSE or otherwise at market prices prevailing atthe time of sale, at prices related to prevailing market prices, including in transactions deemed to be “at the market offerings” asdefined in Rule 415(a)(4) under the Securities Act, or at negotiated prices, by privately negotiated transactions (including block sales)or by any other methods permitted by applicable law. The sales agreements contemplate that, in addition to the issuance and sale by usof shares of our common stock to or through the sales agents, we may enter into separate forward sale agreements under the applicablemaster forward confirmation and the related supplemental confirmation (each, a “forward sale agreement” and, collectively, the“forward sale agreements”), with the Forward Purchasers. If we enter into a forward sale agreement with any Forward Purchaser, weexpect that such Forward Purchaser or its affiliate will borrow from third parties and sell, through the relevant Forward Seller, actingas sales agent for such Forward Purchaser, shares of our common stock to hedge such Forward Purchaser’s exposure under suchforward sale agreement. Unless otherwise expressly stated or the context otherwise requires, the “appointed,” “applicable” or“relevant” Forward Seller with respect to a particular Forward Purchaser will be the Forward Seller entity that is the same entity as, oran affiliate of, such Forward Purchaser. We will not receive any proceeds from any sale of shares of our common stock borrowed by aForward Purchaser or its affiliate and sold through the appointed Forward Seller, but we may receive contingency premiums from theapplicable Forward Purchaser for the contingent forward transactions described below. In one form of forward sale agreement, which we refer to as a “contingent forward transaction” that we may enter into with theForward Purchasers, our obligation to sell and the applicable Forward Purchaser’s obligation to purchase, shares of our Class Acommon stock underlying such forward sale agreement at the applicable forward sale price, is contingent on the applicable ForwardPurchaser’s exercise (or deemed exercise) of such contingency, which may occur in whole or in part from time to time prior tospecified contingency expiration dates. We refer to such Forward Purchaser when acting in such capacity as the “Contingent ForwardPurchaser.” To the extent such contingency is exercised with respect to a portion of such contingent forward transaction, we refer tosuch portion as the “contingency exercised portion” of such contingent forward transaction, and the remaining portion to the extentsuch contingency is not yet exercised but may be exercised as the “contingent portion.” We expect that the initial forward price of thecontingent forward transactions will be above, but not substantially above, the volume-weighted average sale price per share at whichthe
