Did a financial advisor recommend APX New Harmony Partners-D, LP to you? Investors in this oil and gas partnership may have suffered major losses. Soreide Law Group is investigating potential FINRA arbitration claims on behalf of investors who bought this investment through a FINRA-registered brokerage firm.

APX New Harmony Partners-D Will Be Dissolved

APX Energy sent a letter to investors on July 31, 2026. In it, the company admitted that the Partnership's performance fell short of expectations.

According to APX, the wells did not produce the expected volumes of oil. The Partnership also ran a negative operating cash flow for more than a year.

The numbers tell the story. APX reported an operating deficit of $1,638,294 as of December 31, 2025. By June 30, 2026, that deficit had shrunk only slightly, to about $1,548,814.

The most troubling admission came next. APX concluded that the Partnership could not reach sustained profits or repay the deficit, even if oil sold for about $100 per barrel.

As a result, APX decided that dissolving the Partnership is in the best interests of the partners. The company has a tentative deal to sell the Partnership's assets to its operator. APX told investors that any cash from that sale is expected to be “de minimis.” In plain terms, investors should expect little or nothing. Any proceeds would first go toward the Partnership's existing debts.
