Viasat stock (ISIN US92542V1007) closed at USD 76.38 on Nasdaq on September 18, 2026, up 4.6 percent on the day and far above its 52-week low of USD 26.10 but still below the recent high of USD 93.03.

New ViaSat-3 F2 satellite boosts network capacity

On September 18, 2026, Viasat, Inc. announced that its ViaSat-3 F2 satellite has entered service across the Americas, substantially expanding the company's network capacity, flexibility and resilience in the region according to BNamericas.

According to BNamericas, the ViaSat-3 F2 satellite is designed to provide more than one terabit per second of throughput capacity over the Americas, significantly increasing Viasat's ability to meet growing demand for connectivity in aviation, maritime and terrestrial markets.

As BNamericas reports, management emphasizes that the ViaSat-3 constellation now fully operational has effectively tripled the bandwidth available across Viasat's global fleet compared with the pre-constellation state, creating a broader foundation for growth in aviation, maritime, government and broadband services.

Valuation context and recent stock performance

On September 18, 2026, GuruFocus noted that Viasat stock was trading at USD 76.38, implying a gain of 4.6 percent on that day and a sharp recovery from the 52-week low of USD 26.10, while still below the 52-week high of USD 93.03 according to GuruFocus.

According to GuruFocus, the proprietary GF Value metric estimates a fair value of USD 18.83 per share for Viasat, implying that the stock at USD 76.38 is about 305.6 percent above that fair-value estimate.

As GuruFocus explains, Viasat's GF Score stands at 61 out of 100, reflecting above-average overall potential but weakened financial strength and profitability scores of 4 out of 10 each, while the valuation score is only 1 out of 10, underscoring concerns about the current pricing relative to fundamentals.

According to GuruFocus, insiders have sold approximately USD 69.9 million worth of Viasat shares over the past 12 months with no recorded insider buying, which for many investors is a notable risk factor when combined with a valuation more than three times the GF Value estimate.

Operational scale and investor perspective

As BNamericas notes, completion of the ViaSat-3 constellation, including ViaSat-3 F1 in service and ViaSat-3 F3 entering service across Asia-Pacific in August 2026, has effectively tripled the bandwidth available across Viasat's global fleet compared with the pre-constellation level.

According to the same BNamericas report, Viasat operates offices in 24 countries and serves aviation, maritime, government and broadband markets, so the added capacity from ViaSat-3 F2 supports higher-speed connections and adaptive beamforming to allocate capacity dynamically where demand is strongest.

For investors, the combination of a stock price that has risen from USD 26.10 at the 52-week low to USD 76.38 and is still some distance below the USD 93.03 52-week high, together with insider selling of USD 69.9 million and a GF Value of USD 18.83, frames a tension between strong operational expansion and valuation risk, as highlighted by GuruFocus.
