MESSAGE FROM OUR CEO

Dear Fellow Stockholders:

On behalf of the entire board of directors, I would like to express our appreciation for the trust you have placed in us to act as stewards of our company. This year brought important changes to our business.

◾

Maritime Business Divested and All Debt Eliminated. We completed the divestiture of our maritime business, enabling us to retire all debt, including a substantial amount of high-interest debt, while further strengthening our balance sheet.

◾

Achieved Technical, Operational, and Business Successes.

o

We conducted six launches to deploy 39 satellites, including a single-satellite radio frequency geolocation (RFGL) demonstrator — a capability historically requiring two to three satellites to achieve.

o

We expanded our RFGL capabilities to collect and process unencrypted, publicly broadcast voice transmissions from space using AI to transcribe, translate, and summarize even short or noisy signals in near real time.

o

We successfully demonstrated two-way laser communication between our satellites in orbit using optical intersatellite links, marking an advancement in high-speed, space-based data transfer.

o

We announced the launch of AI-driven weather models, advancing next-generation climate simulation and forecasting capabilities.

o

We were awarded significant new contracts which included:

▪

an $11.2 million one-year NOAA contract for RO data;

▪

a $2.5 million NOAA contract for ocean winds data;

▪

a €3 million renewal from EUMETSAT for satellite weather data; and

▪

an award from Deloitte to expand their on-orbit cyber and data operations;

o

We were selected for the Missile Defense Agency SHIELD IDIQ Contract.

◾

Leadership Transitioned. I was appointed as Chief Executive Officer in January 2025, succeeding our founder, Peter Platzer, who transitioned to Executive Chairman. The board of directors has confidence in our leadership team and I am committed to building on the strong foundation that has been established.

◾

Board Refreshed. Dr. Toni Rinow joined our board of directors in October 2025 bringing extensive expertise in financial and accounting strategy, capital markets, and global expansion. John Martinez also joined our board of directors in March 2026 bringing deep government and commercial expertise across national defense, security, and intelligence markets. We are excited to have Dr. Rinow and Mr. Martinez on our board of directors.

◾

New Independent Auditors Appointed. We have engaged KPMG LLP as our independent registered public accounting firm for fiscal year 2025, following PwC’s resignation. We appreciate KPMG LLP’s expertise and look forward to a productive relationship.

We continue to advance our position as a leading global provider of space-based data, analytics, and space services. Our constellation of satellites provides critical data and insights to customers across space reconnaissance, aviation, and weather markets. We remain committed to innovation and operational excellence as we execute on our strategic priorities.

I and the rest of the board of directors invite you to the 2026 Annual Meeting of Stockholders, which will be held virtually. Regardless of whether you are able to join the meeting, we encourage you to vote by proxy. These proxy materials contain detailed information about the matters on which we are asking you to vote.

Thank you for the confidence you place in us through your investment in Spire.

Sincerely,

/s/ Theresa Condor
