“Our business continues to gain momentum. Sequentially, our second quarter performance included a 17.7% revenue increase, a 210 basis point improvement in gross margin to 20%, and an 82% increase in net income to $8.5M, all with just 4.3 million pounds shipped.” Michael L. Shor, President and CEO of Haynes International From our conference call We have invested in manpower and inventory increases, which, when combined with our on-going, relentless pursuit of customer service, innovation, quality, pricing for value, and cost improvements, positions us very well for the future. The recovery we are seeing in our three core markets, led by aerospace, continues to accelerate and drive backlog growth, increasing 99%, year over year. We continue to expect our monthly aerospace shipping volumes to reach our fiscal year 2019 company record run-rate levels by the end of our fiscal year. Higher production rates driven by the backlog growth, along with significant increases in raw material costs, led to cash investments in inventory. Liquidity remains strong at $90.7 million, including $78.5 million available from the credit facility and $12.2 million in cash as of March 31, 2022. FY21 to FY25 projections estimate revenue growth at a 15% CAGR, with aerospace at 25% (highest growth this year from FY21-22). Gross margins remaining over 20% with incremental growth. Operating cash flow positive in FY23. U.S. Pension is at zero-net liability in two years. FY2022 3

Our products are out of this world...literally. Our mission-critical alloys have flown on every Apollo and space shuttle flights, lowered the first Viking Mars Lander on August 20, 1975, and continue to be a part of historic space exploration missions. The Perseverance Rover Landed February 18, 2021 The Curiosity Rover Landed August 6, 2012 February 18, 2021 marked the touchdown of the Perseverance rover at the Jezero Crater on Mars. Like NASA’s Curiosity Mission, our high-temperature, HAYNES® 230® alloy was used in the descent thrusters of the Sky Crane vehicle that safely lowered Perseverance to the Martian surface. FY2022 6

Reasons for optimism about the long-term future of Haynes Encouraging to see expanding profitability with the recovery of gross margin at 20.0%, now exceeding pre-pandemic levels. Further growth in volume and revenue are still ahead. This is driven by expected aerospace returning to pre-pandemic levels by the end of this fiscal year, and additional margin % expansion as process improvements are more fully realized. Significant capital investments have already been made to position us for growth post-pandemic. CapEx approaching depreciation level this year. Our alloy and application development is among the best in the industry. We continue our focus on high-value, differentiated applications and products. Our business model is well-suited for a recovery with ability to provide customers with smaller quantities from service centers, value-added cutting, and JIT delivery. Significant value creation is achieved from our capital allocation strategy combined with margin recovery, which results in a truly different company. Our company has an impressive earnings power potential and a transformed, strong balance sheet. This is the foundation for growth and continued value creation for our shareholders. FY2022 15
