VIAVI Solutions Inc stock surged 6.37% to $39.60 on September 25, 2026, driven by the company's announcement that it achieved CMMC Level 2 certification across key product lines.

What Happened

VIAVI announced it had successfully achieved CMMC Level 2 certification for multiple Aerospace and Defense product lines, including radio test, avionics, synthetic and modular, and PNT. CMMC, or Cybersecurity Maturity Model Certification, is a mandatory standard for entities working with the U.S. Department of Defense.

The stock opened at $38.08 and climbed steadily through the session, reaching its high before settling near the top of the range.

What The Data Shows

The stock has traded in a 52-week range of $12.05 to $60.43 and is currently valued at a market cap of $9.0B. Despite a 40.0% year-to-date revenue increase, the company remains unprofitable with a net margin of -2.0% and an EPS TTM of -0.13. The recent session saw volume of 0.3M shares, which is 0.1x the 3-month average. Over the last 8 sessions, the stock has gained 10.1% from $33.69 to $37.08. Additionally, the 52-week tape recorded 9 fresh 52-week highs and 2 fresh 52-week lows on the same day.
