Small companies raised their 2026 outlooks in a cluster, and one cut its own
Hyliion, KORU, Amprius and Energy Vault all lifted their 2026 numbers in filings this week. Seer went the other way, blaming pressure on academic and government funding.
- Hyliion Holdings reported third-quarter 2026 revenue of $7.5 million and raised its full-year 2026 revenue guidance to about $18 million, the company says. Self-reported m:…3733
- Amprius Technologies reported third-quarter revenue of $39.1 million, up 83% year over year, and raised its 2026 revenue outlook to $145 million, the company says. Self-reported m:…6929
- Energy Vault reported a contract backlog of $2.3 billion and gave preliminary 2027 revenue guidance of $600 million to $700 million, the company says. Self-reported m:…6910
- KORU Medical Systems reported third-quarter revenue of $11.6 million, up 11.2% on the prior-year period, and revised full-year guidance to $48.0 million to $48.5 million, the company says. Self-reported m:…3498
- Seer cut its full-year 2026 revenue guidance to $13.5 million to $14.5 million, attributing the cut to pressure on academic and government funding that extended sales cycles, the company says. Self-reported m:…2370
What the filings said
Four small public companies raised their 2026 outlooks in filings this week, and the raises share a pattern: each one pointed to orders already in hand rather than hope. Hyliion Holdings reported third-quarter revenue of $7.5 million and lifted its full-year 2026 revenue guidance to about $18 million, while Amprius Technologies reported $39.1 million in third-quarter revenue, up 83% on a year earlier, and raised its 2026 revenue outlook to $145 million. m:…3733 m:…6929
KORU Medical Systems reported third-quarter revenue of $11.6 million, up 11.2% on the prior-year period, and revised its full-year guidance to $48.0 million to $48.5 million. The company also reported net income of $0.2 million against a net loss of $0.8 million a year earlier, and adjusted EBITDA of $1.3 million against $0.1 million. Energy Vault reported third-quarter revenue of $13.1 million, affirmed full-year 2026 guidance of $290 million to $310 million, and gave preliminary 2027 revenue guidance of $600 million to $700 million. m:…3498 m:…6910
Seer went the other way. The company reported third-quarter revenue of $4.0 million and cut its full-year 2026 revenue guidance to $13.5 million to $14.5 million, attributing the reduction to continued pressure on academic and government funding that has stretched out sales cycles. It reported a net loss of $13.7 million for the quarter, though operating expenses fell 23% to $16.5 million, and it ended the quarter with about $198.1 million in cash, cash equivalents and investments. m:…2370
The orders behind the raises
The orders behind the numbers are concrete. Amprius says it secured a $75 million contract from the U.S. Department of War, and Hyliion says it expects about $8 million in additional military contract awards before the end of 2026. Energy Vault says its contract backlog reached $2.3 billion as of November 10, 2026, and that it completed the acquisition of 2.3 GW of U.S. battery storage development projects from Goshe Energy Storage. m:…6929 m:…3733 m:…6910
Cash is not the constraint in this group. Hyliion ended the quarter with $121.4 million in cash and investments, and Energy Vault reported total cash and cash equivalents of $236 million as of September 30, 2026. KORU expects its year-end cash balance to be greater than $8.0 million. That matters because the question for these companies is rarely survival; it is whether a raised outlook turns into collected revenue, and the filings give readers the backlog and the cash to check against next quarter. m:…3733 m:…6910 m:…3498
The details that cut against a simple growth story
There are details that cut against a simple growth story. Seer's board completed a review and the company will remain an independent public company, and the investigative staff of the International Trade Commission recommended granting the exclusion and cease-and-desist orders Seer sought against Nanomics Biotechnology. Amprius introduced a new battery model, the SiCore 500, and expanded its relationship with Quantum Systems, while Hyliion delivered an early adopter KARNO power module to the U.S. Navy and expects to complete an 800-kW system for a Navy vessel in early 2027. m:…2370 m:…6929 m:…3733
The pattern to watch is narrow. Four raises and one cut in a single filing day do not make a small-cap recovery, but they do show where demand is firm enough for companies to put a higher number in a filing: defense power, medical devices with a recurring patient base, batteries and storage. Seer's cut shows the other side of the same week: when the customer is a university or a government lab, the sales cycle is the risk. The next check is the fourth quarter, when KORU's Adam Kalbermatten said revenue growth is expected to reaccelerate and Hyliion's military awards are due to land. m:…3498 m:…3733 m:…2370
What is still unresolved
- Whether Hyliion's expected $8 million in additional military awards arrives before the end of 2026.
- Whether Seer's extended sales cycles shorten, or funding pressure persists into 2027.
- Whether Energy Vault's $2.3 billion backlog converts into the $600 million to $700 million of 2027 revenue it guided.
- Whether KORU's expected fourth-quarter reacceleration in revenue growth materialises.
