Recent Form 8-K reports furnish quarterly and annual results announcements, including management updates on KARNO development, testing, customer applications, military programs, and related business milestones.
The company’s proxy materials cover board matters, shareholder voting items, executive compensation, equity awards, pay-versus-performance tables, and governance disclosures.

Hyliion Holdings Corp. has established an at-the-market equity program to offer and sell up to $100,000,000 of common stock from time to time through Needham & Company, LLC and Northland Securities, Inc. as sales agents. Sales may be made on NYSE American under the symbol HYLN or through other permitted methods, with the sales agents earning up to 3% of gross proceeds as commissions. As of June 30, 2026, Hyliion had 178,597,218 shares outstanding; at an assumed price of $3.93 per share this program would add up to 25,445,293 new shares. Net tangible book value was $166.5 million or $0.93 per share, and would increase on an as-adjusted basis to $263.2 million or $1.29 per share, implying $2.64 per-share dilution to new investors at the assumed price. The company plans to use any net proceeds for general corporate purposes, including potential capital expenditures, and warns that investing in its stock involves a high degree of risk.
Hyliion Holdings Corp. reported higher R&D services revenue while remaining loss-making as it advances commercialization of its KARNO Power Module. Second-quarter 2026 revenue was $4.9 million, up from $1.5 million a year earlier, driven by U.S. government R&D contracts. For the first six months of 2026, revenue rose to $7.8 million from $2.0 million, while net loss improved to $25.7 million from $30.7 million, reflecting lower R&D spending and exit benefits from its powertrain wind-down.
At June 30, 2026 Hyliion held $13.2 million in cash and cash equivalents and $119.2 million in investments, with total current liabilities of $9.4 million, supporting a going-concern outlook for at least 12 months. All revenue currently comes from R&D services, heavily concentrated in a single U.S. government customer. The company has a cost-plus-fixed-fee Navy contract of up to $16.0 million plus a Phase II contract of up to $1.5 million, and in July 2026 won a new ONR contract of up to $41.7 million to develop multi-megawatt KARNO systems through 2029.
To fund commercialization and additive manufacturing capacity, Hyliion is pursuing up to $15 million of equipment financing and established a $100 million at-the-market equity program, which it expects to use opportunistically and which would dilute existing stockholders if utilized.
Hyliion Holdings Corp. reported strong second-quarter 2026 progress tied to its KARNO™ Power Module platform and military programs.

Gross profit was $0.4 million, with operating expenses of $15.7 million and a net loss of $13.9 million. For the first half of 2026, revenue reached $7.8 million and the net loss improved to $25.7 million.
The company secured a $41.7 million U.S. Navy contract to develop multi-megawatt KARNO Power Modules and expects additional military awards that could bring total 2026 military funding to nearly $50 million. Hyliion increased full-year 2026 revenue guidance to approximately $15 million, a 50% increase, and now forecasts year-end cash and investments of $115 million to $120 million after expected net cash use of $30 million to $35 million. It ended the quarter with $132.4 million in cash and investments and highlighted additive manufacturing advances that could improve printer throughput by up to three times while enabling capital-efficient production scaling.
