Rocket Lab Gains 2.2% in the Past 3 Months: Should You Buy the Stock?

Rocket Lab (RKLB) shares gained 2.2% in three months, driven by 48% revenue growth in Q3 2025, successful NASA and iQPS missions, and the anticipated Neutron rocket launch in H2 2025. Despite strong growth potential and positive 2025 earnings estimate revisions, the company faces high operating costs from ongoing R&D and trades at a significant premium with a 26.59x forward Price/Sales ratio against an industry average of 9.28x. Analysts maintain a "Hold" rating, recommending investors await a more favorable entry point due to its valuation and persistent losses.

Analysis

Rocket Lab USA (RKLB) shares gained 2.2% in the past three months, outperforming its industry but lagging the broader Aerospace sector and S&P 500. This performance is driven by strong Q3 2025 results, which reported 48% year-over-year revenue growth and improved net losses. Key operational milestones, including successful NASA and iQPS missions, further support investor confidence.

The company's future growth trajectory is significantly tied to the anticipated launch of its Neutron rocket in the second half of 2025, which will expand launch capacity and enable competition with larger industry players. Analysts project a solid 36% revenue improvement for RKLB in 2025, with recent upward revisions to earnings estimates reflecting increasing confidence.

Despite growth indicators, RKLB faces significant financial headwinds from high operating costs due to extensive R&D investments in advanced technologies, leading to ongoing losses. The stock trades at a substantial premium, with a forward 12-month Price/Sales ratio of 26.59x, significantly above the industry average of 9.28x.

This premium valuation is evident compared to peers like AAR Corp. (AIR) and Curtiss-Wright Corporation (CW), which trade at P/S multiples of 0.98x and 5.57x, respectively. The current Zacks Rank #3 (Hold) reflects a cautious stance, suggesting that while long-term prospects are solid, the present valuation and cost structure warrant a disciplined approach for new investors.

Key Decisions for Investors

• New investors should consider waiting for a more attractive entry point, given Rocket Lab's significant premium valuation (26.59x P/S F12M) relative to its industry and ongoing high operating costs.
• Monitor the successful execution of the Neutron rocket launch in H2 2025, as this is a critical catalyst for expanding market share and achieving profitability.
• Existing investors may consider holding positions, acknowledging the company's strong long-term growth potential and robust sales expectations, while closely watching progress towards improved net losses.
