LRMR · Larimar Therapeutics, Inc. · Shareholders & Ownership
Substantial doubt about the company's ability to continue as a going concern.
“While the Company expects its cash, cash equivalents and marketable securities will fund its forecasted operating expenses and capital expenditure requirements into the third quarter of 2027, these cash resources are not sufficient to fund the Company's planned operations for a period of at least one year from the date these unaudited condensed consolidated financial statements are issued. The Company will need to raise additional capital to fund its ongoing operations. The Company continues to evaluate opportunities to further finance its operating cash needs through a combination of some, or all, of the following: equity or debt offerings, royalty financings, collaborations, strategic alliances, and/or marketing, distribution or licensing arrangements. In addition, the Company believes it will be eligible for the FDA's rare pediatric disease priority review voucher which could then be sold if nomlabofusp receives FDA approval. There is no assurance, however, that additional financing will be available when needed or that the Company will be able to obtain financing on terms acceptable to the Company. If the Company is unable to obtain funding when required in the future, the Company could be required to delay, reduce, or eliminate research and development programs, or commercialization efforts, which could adversely affect its business prospects. These conditions raise substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Aug 4, 2026

Shares are restated onto today's split basis. Change compares each row with the same holder's previous filing in the same source; a dash means there is none to compare. Nested 13D/G, insider and fund rows are not summed, since a 13F report already holds them.
