What does it do?
Astronics is a growth business that earns money by designing and manufacturing specialized components for aircraft cabins, airframes, and military testing platforms. The company primarily sells power generation systems that let passengers charge devices, lighting systems for cabins and cockpits, and connectivity hardware for in-flight internet. Most revenue comes from original equipment manufacturers like Boeing and Airbus, who pay Astronics to install these systems during the initial build. A smaller but significant portion comes from airlines that pay for "retrofits" to upgrade older planes with modern amenities.
Where does revenue come from?
The vast majority of revenue is generated by the Aerospace segment, which accounted for 92% of sales in the most recent quarter. Within this segment, commercial transport is the dominant market, driven by lighting, power, and seat motion systems. The remaining 8% comes from the Test Systems segment, which sells diagnostic equipment to the U.S. military and transit agencies. Most of this revenue is earned in North America, though the company serves airlines and manufacturers globally.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Astronics serves a concentrated group of global airframe manufacturers, major airlines, and military branches. Its top customers include industry giants like Boeing, which is a major driver of the company’s airframe power and lighting sales. In the most recent quarter, the company reported record quarterly bookings of $306.2 million, resulting in a book-to-bill ratio of 1.18. The total backlog reached a record $780.6 million at the end of the second quarter, with 82% of that expected to be converted into revenue over the next twelve months.
What gives it staying power?
Astronics has staying power because its products are "designed-in" to specific aircraft platforms and require complex FAA certifications to be replaced. Once a part is certified and installed, airlines rarely switch suppliers due to the extreme costs and regulatory hurdles of recertifying a different component.
Where is it headed?
Management is making a significant bet on expanding its role in next-generation military programs and advanced cabin motion systems. By acquiring Bühler Motor Aviation, the company is moving deeper into the seat actuation market to capture more value from luxury cabin upgrades. If these programs scale, they will diversify revenue away from traditional commercial transport lighting.
Astronics is experiencing a sharp revenue acceleration, with sales growing 27% to a record $260 million in the most recent quarter. This growth is finally moving the company past its pandemic-era struggles as it leverages a record $781 million backlog to drive higher production volumes.
Free cash flow has turned positive and reached $30.1 million in the latest quarter, signaling that the business is no longer burning cash to support its growth. While the company is investing heavily in a new Seattle facility, its underlying operations are now generating enough cash to fund these capital projects internally.
The balance sheet is in a position of manageable leverage, with $310.3 million in long-term debt offset by $253.2 million in available liquidity. While a debt-to-equity ratio of 1.78 is high, the recent refinancing and improving cash flows have significantly reduced the risk of a liquidity crunch.
Astronics is a business in a clear financial upturn where record sales are finally translating into record operating income.
Astronics does not pay a dividend and has historically used its cash to fund acquisitions and internal growth. The company does not have an active share buyback program, and the share count rose by approximately 6.6% over the last year, primarily due to the conversion of notes and employee stock awards. This means an owner's slice of the company has been slightly diluted as the business scales. Investors should hold this stock for potential share price gains rather than for any cash return in the near term.
The Aerospace segment achieved a record 20.3% operating margin as higher production volumes allowed the company to spread fixed costs over more units. This operating leverage is the engine of the current thesis, proving that the company can generate significant profits once it reaches a certain scale.
The Test Systems segment continues to be a drag on overall performance, contributing only $0.6 million in operating profit despite a large increase in sales. Profitability in this division is currently held back by "under-absorption," meaning the company has a large fixed cost base that won't be fully profitable until more government contracts move into full production.
The aerospace and defense materials market is currently worth approximately $45 billion and is projected to exceed $60 billion by 2028. It is a rationally structured industry where high technical requirements allow for stable pricing, though the race for lighter materials creates constant pressure to innovate. Astronics stands as a dominant niche player in cabin electronics, enjoying a long growth runway as airlines prioritize device charging and high-end seat features.
The competitive dynamic in this market is rationally structured because the costs of failure are too high for a race to the bottom on price. Barriers to entry are high due to the years of testing required to get any part certified for flight. This creates a market where competition happens over new designs rather than current production.
Heico is the most dangerous threat because it specializes in creating cheaper, FAA-approved alternatives to original parts, which could erode aftermarket margins. Safran and Woodward use their massive scale to bundle products together, making it harder for a smaller player like Astronics to win entirely new airframe programs. Ducommun competes for the same engineering talent and defense contracts, though it focuses more on structural parts than cabin electronics.
Astronics is holding its ground and gaining share in cabin power, evidenced by a book-to-bill ratio of 1.18 in the most recent quarter.
The primary source of protection is switching costs tied to the regulatory environment of commercial aviation. Once Astronics is selected for a plane like the 737 MAX, the cost for an airline to swap out the wiring and certification is prohibitive. This creates a "sticky" revenue stream that lasts for the decades-long life of the aircraft.
Collectively, a 20.4% ROIC and rising operating margins prove that the business has real pricing power during this part of the cycle. However, Astronics lacks a strong moat because its revenue is heavily concentrated in a few major customers who can demand pricing concessions when new contracts are negotiated.
The moat is strengthening as the record backlog locks in several years of guaranteed revenue. New military contract finalizations, like the MV-75 FLRAA program, provide evidence that the company is winning long-term positions on next-generation platforms.
Raised 2026 revenue guidance to record $1.03B following three straight record backlog quarters.
Acquired Bühler Motor Aviation for $40M cash to expand into growing seat actuation market.
CEO Peter Gundermann has led the company since 2003 and holds a significant personal stake.
Capital Allocation Track Record
Peter Gundermann has led Astronics for over two decades, demonstrating a rare ability to navigate the extreme cycles of the aerospace industry without diluting the core business. His strategic judgment was visible in the decision to invest in cabin power and connectivity years before they became industry standards, a bet that is now yielding record margins. Management has successfully repaired the balance sheet following the pandemic, using a mix of disciplined cost-cutting and timely acquisitions to position the company for the current production ramp.
Governance risk is concentrated in the person of Peter Gundermann, who serves as Chairman, CEO, and President, creating a high level of key-person dependency. While there is a deep bench of experienced segment presidents, the dual-role structure limits the board's independent oversight compared to larger peers. However, the alignment remains high as the founding family’s interests are tied to long-term share performance rather than short-term bonuses.
We expect revenue to grow from $1.0B in FY2026 to $1.3B in FY2031 (~4% CAGR), with EPS growing from $2.71 to $4.51 (~11% CAGR). Revenue grows as the company maintains its leading share of the recovering commercial aircraft lighting and power market. Margins expand as higher production volumes allow the company to better cover its fixed manufacturing and engineering costs. EPS grows faster than revenue because profit margins are recovering from a cyclical low point. Operating margin expected to reach ~15% by FY2031.
Record backlog converts to high-margin revenue as supply chains stabilize. The $781 million backlog represents guaranteed future work that will drop more profit to the bottom line as production volume increases.
Military radio test program ramps to full-rate production through 2028. Moving the TS-4549 T program from development to production will turn the Test segment from a drag on earnings into a growth driver.
Cabin power demand grows as devices require higher wattage charging. As passengers bring more power-hungry devices on board, airlines are forced to upgrade to Astronics' higher-wattage power modules.
Boeing production delays or quality issues stall aircraft deliveries. Since Boeing is a major customer, any halt in its production line immediately stops the flow of revenue for airframe components.
Labor and material inflation erode the profitability of fixed-price contracts. If the cost to build parts rises faster than the company can raise prices on long-term contracts, margins will shrink.
Competitors successfully certify low-cost alternative power systems for the aftermarket. If rivals like HEICO break into the cabin power niche, Astronics will lose its lucrative recurring revenue from replacement parts.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We value Astronics based on the cash and profits it is expected to produce over the next five years. This method is the best fit because the company is currently in a "ramp-up" phase with a record backlog that a simple look at next year's earnings would understate.
Multiplying the expected 2031 profit of $4.51 by a 25x multiple gives a future price of $113, which equals $72 today after adjusting for time and risk. We chose a 25x multiple because high-quality aerospace peers like HEICO and Curtiss-Wright typically trade between 20x and 30x. This calculation also adds in the value of the cash the company earns in the years leading up to 2031, discounted back to today's value at a 10% rate.
Priced instead on next year's earnings of $3.12 at a 20x multiple, we get a value of $62 — very close to the current stock price. This second method uses a slightly lower multiple than its rivals to account for the company's high debt levels. Because our primary $72 target and this $62 cross-check sit within 15% of each other, it gives us confidence that the stock is currently entering a "fair value" zone as the business recovers.
The biggest risk is a prolonged production slowdown at Boeing, which is a major customer for Astronics' cabin and power systems. A drop in aircraft deliveries would force the company to carry too much inventory and would likely compress the valuation multiple from 25x down to 15x. This would knock roughly $25 off the per-share fair value. Watch the monthly Boeing delivery reports for any signs of a sustained dip below 30 planes.
Bear case ($54): Boeing 737 MAX delivery rates fall below 30 planes per month for two consecutive quarters; or Operating margins stall below 10% due to persistent labor or supply chain costs.
Bull case ($92): Test Systems segment revenue exceeds $150 million annually as military demand ramps; or Debt reduction happens faster than expected, lowering interest costs by over 40%.
