Hyliion stock (ISIN US4491091074) is priced at USD 3.43, with a market capitalization of USD 635.81 million and a 52-week range of USD 1.56 to USD 8.49. A class action filing and related investor alerts have kept the shares in view, while the latest reported quarter showed revenue of USD 9.25 million and EBITDA of USD -52.23 million.

Litigation stays in view

On September 2, 2026, several investor notices said a securities class action had been filed over Hyliion Holdings Corp. and that the proposed class period ran from May 12, 2026 through June 23, 2026. One filing said the stock fell 17.2 percent to USD 6.10 on June 23, 2026 and then another 19.3 percent to USD 4.92 on June 24, 2026.

The market reaction gives the story its weight. The numbers are concrete: USD 7.37 on June 22, 2026, USD 6.10 on June 23, 2026, and USD 4.92 on June 24, 2026.

Quarterly figures matter

The latest figures visible in the current data set show Q2 2026 EPS of USD -0.08, missing the estimate of USD -0.07 by 14.29 percent. Revenue for the period stood at USD 9.25 million, while EBITDA was USD -52.23 million.

That combination is what investors have to weigh: a small revenue base, a negative earnings line, and a market value still above USD 600 million as of September 1, 2026. The gap between the Q2 2026 EPS result and the estimate was USD 0.01 per share.

KARNO stays central

Hyliion still ties much of its story to KARNO Power Modules and the data-center angle that surfaced in May 2026. The latest investor-alert language also points back to that same commercial narrative, not to a broader operating turnaround.
