Core Viewpoint - The recent sell-off in space stocks has created investment opportunities as many companies have become cheaper to invest in, despite the overall challenges in the space industry [1][3]. Investment Opportunities - The article highlights three of the cheapest space stocks that may offer upside potential: BlackSky, Redwire, and Spire Global [5]. BlackSky - BlackSky has a market capitalization of less than $270 million and a price-to-sales (P/S) ratio of 2.6, making it one of the cheapest space stocks [6]. - The company is currently unprofitable and is not expected to earn its first profit before 2027, with an annual negative free cash flow of approximately $56 million and only $52 million in cash reserves [7]. - BlackSky may need to raise additional capital through debt or stock sales, or potentially sell itself to a larger company [8]. Redwire - Redwire has a market capitalization of $863 million and a P/S ratio of 2.8, with three times the annual revenue of BlackSky [9]. - The company is also unprofitable, with cash reserves of less than $34 million, but it burned less than $24 million last year [10]. - Analysts suggest that Redwire could become free cash flow-positive as early as this year and achieve GAAP profitability by 2026, which would be a significant milestone for the company [11][12]. Spire Global - Spire Global has a market capitalization of $345 million and a P/S ratio of 3.1, which may change significantly in the near future [14]. - The company is negotiating to sell its maritime data business to Kpler, which could yield a cash windfall of $241 million, allowing it to pay off debts and fund operations for the next three years [15]. - Successfully closing this deal could serve as a near-term catalyst for Spire's stock price, potentially leading to significant gains [16].
